The disposable vacuum fresh-keeping soft barrel and the vacuum fresh-keeping water taking device provided by the embodiment of the invention have the following advantages:

1. the bottom of the disposable vacuum fresh-keeping soft barrel is provided with the first reinforcing groove which is perpendicular to the side wall of the barrel body, so that the bottom of the hollow barrel is not easy to deform, and the production and the transportation of products are facilitated; when the barrel body of the disposable vacuum fresh-keeping soft barrel product is compressed, the first reinforcing groove perpendicular to the side wall of the barrel body can reinforce the strength of the barrel bottom, so that the barrel bottom is prevented from deforming to influence the contraction effect of the barrel wall during compression.

2. The bucket bottom is characterized in that a first concave part is arranged in the middle area of the bucket bottom, the first concave part comprises a first arc-shaped concave area and a second arc-shaped concave area, and the curvature radius of the first arc-shaped concave area is larger than that of the second arc-shaped concave area.

3. The first reinforcement groove is provided as a first groove portion and a second groove portion. The first groove body part is arranged at the barrel bottom and is vertically arranged with the corresponding barrel side wall, so that the strength of the barrel bottom in the transverse direction is enhanced. The second groove portion is provided on the first arc-shaped depressed region to enhance both strength of the tub bottom in the axial direction and strength in the lateral direction.

4. And setting the included angle range between the tangent plane of the joint of the bucket shoulder and the side walls of the bucket body and the side wall of the bucket body corresponding to the joint to be 20-70 degrees, so that the bucket shoulder is inclined to the side wall of the bucket body, and the shoulder of the disposable vacuum fresh-keeping soft bucket is contracted. According to the arrangement mode, when the strength of the barrel shoulder area is enhanced, the phenomenon that the corners of the polygonal column are whitened due to excessive stretching can be avoided when the barrel shoulder area is stretched too much, and the damage of the disposable vacuum preservation soft barrel can be caused seriously. In addition, because the shoulder part of the disposable vacuum fresh-keeping soft barrel is in a contraction shape, the distance between the connecting part of the barrel shoulder and the side walls of the barrel body and the central axis of the barrel body is greater than or equal to the distance between the trough end of the wavy fold and the central axis of the barrel body, but is less than or equal to the distance between the peak end of the wavy fold and the central axis of the barrel body. The design mode can enable the barrel shoulder and the barrel body to be smoothly transited. In addition, as the barrel shoulder of the disposable vacuum refreshing soft barrel shrinks inwards, the transverse stretching ratio of the barrel shoulder at the blowing time is smaller than that of the barrel body during the manufacturing process of the disposable vacuum refreshing soft barrel. Therefore, when the barrel is stretched, relatively more material is accumulated in the barrel shoulder area, so that the thickness of the barrel shoulder area is increased, and the strength of the barrel shoulder is enhanced. And the design of the inclined barrel shoulder can ensure that when the disposable vacuum fresh-keeping soft barrel is compressed to a position close to the limit position, the drinking water in the water barrel can also effectively flow to the barrel opening.

When the disposable vacuum fresh-keeping soft barrel is placed on the vacuum fresh-keeping water taking device, the barrel shoulder can not deform under the pressure action of water.

6. The second reinforcing groove is arranged to be inwards recessed from the barrel shoulder, and a plurality of second rib structures are formed in an accommodating cavity formed by the barrel body, the barrel bottom and the barrel shoulder. Flow guide portions may be formed between adjacent second rib structures. When the water amount in the disposable vacuum fresh-keeping soft barrel is less and less, the flow guide part can guide the drinking water out of the barrel more conveniently.

7. Because a flow guide part is formed between the adjacent second rib structures, and the projection of the first rib structure in the axial direction of the barrel body is positioned in the projection of the flow guide part in the axial direction of the barrel body. When the disposable vacuum fresh-keeping soft barrel is compressed to the end, the first convex edge structure can be embedded into the flow guide part. On one hand, the first rib structure and the flow guide part are arranged in a matched mode, so that the compressibility degree of the barrel body can be increased; on the other hand, when the first rib structure is embedded into the flow guide part, the first rib structure can extrude the water flow in the flow guide part, so that the drinking water in the barrel can better flow out.

8. When the disposable vacuum fresh-keeping soft barrel is arranged on a vacuum fresh-keeping water taking device, the arrangement length of a water guide core of the vacuum fresh-keeping water taking device is required to satisfy the following relation: when the disposable vacuum fresh-keeping soft barrel is compressed to the state that the first reinforcing groove is contacted with the barrel shoulder area, the distance between the tail end of the water guide core and the bottommost end of the second arc-shaped sunken area is larger than or equal to zero. The purpose of the arrangement is that when the disposable vacuum fresh-keeping soft barrel is compressed to the limit, the water guide core of the vacuum fresh-keeping water taking device cannot prop against the barrel bottom, so that the barrel body cannot be compressed continuously.

Referring to fig. 1 and 5, an embodiment of the present invention provides a disposable vacuum refreshing soft barrel 100. The disposable vacuum fresh-keeping soft barrel 100 comprises a barrel body 110 and a barrel bottom 120. The tub bottom 120 is disposed at one end of the tub 110 and is hermetically connected to the tub 110. The tub body 110 and the tub bottom 120 together form a receiving chamber 200 for storing water.

Referring to fig. 2 to 5, the tub 110 includes a plurality of tub sidewalls 111 to 116. The plurality of barrel side walls 111-116 are connected end to form a polygonal prism structure. Each of the tub side walls 111-116 is provided with a wave-shaped corrugation 1111 distributed in an axial direction of the tub 110 so that the tub side walls 111-116 can be compressed in an axial direction. By the arrangement of the wavy folds 1111, when the disposable vacuum fresh-keeping soft barrel 100 is used, the disposable vacuum fresh-keeping soft barrel 100 can be continuously compressed along the extending direction of the wavy folds 1111 under the action of atmospheric pressure along with the continuous outflow of the drinking water in the accommodating cavity 200. The arrangement mode can prevent the outside air from entering the disposable vacuum fresh-keeping soft barrel 100 in the process of flowing out the drinking water, thereby influencing the water quality in the disposable vacuum fresh-keeping soft barrel 100. In addition, the disposable vacuum refreshing soft tub 100 can be discarded after the drinking water therein is used up, thereby ensuring the quality of the stored drinking water. In this embodiment, the bowl sidewalls 111-116 are rounded to form a hexagonal prism shape. The corrugations 1111 include peak ends 1112 and valley ends 1113, and the peak ends 1112 and the valley ends 1113 between two adjacent barrel sidewalls 111-116 are alternately arranged in the axial direction of the barrel 110. At this time, the peak ends 1112 and the valley ends 1113 of the adjacent barrel sidewalls 111-116 are not pressed against each other when the barrel 110 is compressed, so that the change rate of the inner circumference and the outer circumference of the barrel 110 is low. That is, when the disposable vacuum refreshing soft barrel 100 is used, the barrel 110 is linearly compressed, and the deformation amount is small, so that the compression of the barrel 110 is easier. It is understood that the number of the side walls of the barrel is not limited to 6 as described in the present embodiment, and may be 4, or 8, or more than 10. In this case, the side wall of the barrel may be formed into a quadrangular prism, an octagonal prism, a decaprism, or the like.

Referring to fig. 3 and 4, the barrel bottom 120 includes a plurality of first reinforcement grooves 121-126. The plurality of first reinforcement grooves 121-126 are disposed around a middle region of the tub bottom 120 and extend outward from the middle region of the tub bottom 120. The number of the plurality of first reinforcing grooves 121-126 corresponds to the number of the plurality of barrel sidewalls 111-116, and each first reinforcing groove 121-126 is perpendicular to its corresponding barrel sidewall 111-116. In this embodiment, the first reinforcement groove 121 is disposed perpendicular to the tub side wall 111; the first reinforcement groove 122 is disposed perpendicular to the tub side wall 112; the first reinforcement groove 123 is disposed perpendicular to the tub side wall 113; the first reinforcement groove 124 is disposed perpendicular to the tub side wall 114; the first reinforcement groove 125 is disposed perpendicular to the tub side wall 115; the first reinforcement groove 126 is disposed perpendicular to the tub side wall 116.

Specifically, the tub bottom 120 includes a bottom portion 127 and a connection portion 128. The bottom 127 has the same shape as the end surface of the polygonal prism structure formed by the plurality of barrel side walls 111-116. When the size of the bottom 127 is smaller than the size of the end surface of the polygonal prism structure formed by the plurality of barrel sidewalls 111-116. The connecting portion 128 is arc-shaped and is connected between the bottom 127 and the plurality of barrel sidewalls 111-116. That is, in the present embodiment, since the tub side walls 111 to 116 are rounded to form a hexagonal prism shape, the bottom 127 is also formed in a hexagonal shape accordingly. The distance between each edge of the bottom 127 and the midpoint of the bottom 120 is less than the distance between the plurality of barrel sidewalls 111-116 and the midpoint of the bottom 120. The plurality of first reinforcement grooves 121-126 are provided at the bottom 127 of the tub bottom 120. And the ends of the plurality of first reinforcing grooves 121 to 126 extend to a boundary between the bottom 127 of the tub bottom 120 and the connection portion 128 of the tub bottom 120.

The first reinforcing grooves 121-126 are arranged on the bottom 120 of the disposable vacuum refreshing soft barrel 100 for the purpose of:

in one aspect, the first reinforcement grooves 121-126 can increase the strength of the bottom 120, so that the disposable vacuum refreshing soft barrel 100 is not easily deformed when being empty, thereby facilitating the production and transportation of the product. Without the first reinforcement grooves 121-126, the disposable soft vacuum pail 100 is easily deformed in an empty state, thereby causing a great change in height of each pail. After the disposable vacuum fresh-keeping soft barrel 100 is filled and sealed, the barrel body is easy to incline, so that the phenomena of unstable barrel moving and easy barrel dumping are generated on a production line.

On the other hand, since the first reinforcement grooves 121-126 are disposed perpendicular to the corresponding barrel sidewalls 111-116, when the bottom 120 of the soft disposable vacuum refreshing barrel 100 is compressed, the first reinforcement grooves 121-126 disposed perpendicular to the barrel sidewalls 111-116 can make the bottom 120 an integral body to prevent the bottom 120 from being deformed when compressed. In addition, the first reinforcement grooves 121 to 126 disposed perpendicular to the barrel sidewalls 111 to 116 may also serve as guides when the barrel 120 is compressed, allowing the barrel sidewalls 111 to 116 to be compressed uniformly as a whole. Without the first reinforcement grooves 121-126, the bottom 120 of the disposable vacuum freshener drum 100 is first susceptible to irregular deformation when collapsed, thereby affecting the compression effect of the drum sidewalls 111-116.

On the other hand, the ends of the first reinforcing grooves 121 to 126 extend only to the boundary between the bottom 127 of the tub bottom 120 and the connecting portion 128 of the tub bottom 120. When the disposable vacuum freshener drum 100 is compressed, the connecting portion 128 of the bottom 120 is first deformed. When the disposable vacuum refreshing soft barrel 100 continues to be compressed, the barrel body 110 continues to deform, so that the whole disposable vacuum refreshing soft barrel 100 is compressed. The above arrangement further increases the compressibility of the disposable vacuum refreshing soft barrel 100.

Referring to fig. 3 and 5, in the present embodiment, the barrel bottom 120 further includes a first recess 129. The first recess 129 is provided at a middle region of the tub bottom 120. The first recess 129 includes a first arcuate recess region 1291 and a second arcuate recess region 1292. The radius of curvature of the first curved recessed region 1291 is greater than the radius of curvature of the second curved recessed region 1292. The first recess 129 is provided in the middle region of the tub bottom 120 to enhance the strength of the tub bottom 120 in the axial direction, so that the tub bottom 120 is not easily deformed in the axial direction even when compressed. Also, since the first recess 129 includes a first arc-shaped recess region 1291 and a second arc-shaped recess region 1292, the radius of curvature of the first arc-shaped recess region 1291 is greater than that of the second arc-shaped recess region 1292. The segmented first and second arcuate recessed

regions

1291 and 1292 may further enhance the strength of the bucket bottom 120 in the axial direction.

When the tub bottom 120 is provided with the first recess 129, one or more of the plurality of first reinforcement grooves 121 to 126 may further include a first groove portion and a second groove portion, as needed. The first groove portion is disposed at the bottom 127 of the tub bottom 120 and perpendicular to the corresponding side wall of the tub body. The second groove portion is disposed on the first arc-shaped depression region 1291 and forms a first preset angle with the bottom 127 of the tub bottom 120. In this embodiment, the first preset angle is in a range of 10 degrees to 45 degrees. Specifically, the first reinforcement groove 121 includes a first groove portion 1211 and a second groove portion 1212; the first reinforcing groove 122 includes a first groove portion 1221 and a second groove portion 1222; the first reinforcing groove 123 includes a first groove body portion 1231 and a second groove body portion 1232; the first reinforcement groove 124 includes a first groove portion 1241 and a second groove portion 1242; the first reinforcing groove 125 includes a first groove portion 1251 and a second groove portion 1252; the first reinforcement channel 126 includes a first channel portion 1261 and a second channel portion 1262. The first channel portions 1211-1261 are disposed at the bottom 127 of the tub bottom 120 and are disposed perpendicular to the tub side walls 111-116 to which they correspond. The second slot portions 1212-1262 are disposed in the first arc-shaped recessed region 1291 and respectively form a first predetermined angle with the bottom 127 of the tub bottom 120. The first reinforcement grooves 121 to 126 are provided as a first groove portion and a second groove portion for the purpose of: while reinforcing the strength of the tub bottom 120 in the lateral direction and the strength in the axial direction. The first channel portions 1211-1261 are provided at the tub bottom 120 and are disposed perpendicular to the corresponding tub side walls 111-116 to reinforce the strength of the tub bottom 120 in the lateral direction. The second slot portions 1212-1262 are provided on the first arcuate recessed region 1291 to simultaneously increase the strength of the tub bottom 120 in the axial direction and the strength in the transverse direction.

The first reinforcement grooves 121 to 126 are recessed from the bottom 127 of the tub bottom 120 toward the extension direction of the tub side walls 111 to 116, and first rib structures 1213 to 1263 are formed in the accommodation chamber 200 formed by the tub bottom 120 and the tub 110. In this embodiment, since the plurality of first reinforcement grooves 121-126 are disposed perpendicular to the corresponding tub sidewalls 111-116, the plurality of first rib structures 1213-1263 formed by the plurality of first reinforcement grooves 121-126 being inwardly recessed are also disposed perpendicular to the corresponding tub sidewalls 111-116. Specifically, the first rib structures 1213 to 1263 are located on the symmetry plane of the corresponding barrel sidewalls 111 to 116, and the symmetry plane passes through the central axis of the disposable vacuum freshener 100.

Referring to fig. 5 to 8, the disposable vacuum freshen-up soft barrel 100 further includes a barrel shoulder 130 and a barrel opening 140. The barrel shoulder 130 and the barrel bottom 120 are respectively disposed at opposite ends of the barrel body 110. The barrel body 110, the barrel bottom 120 and the barrel shoulder 130 together form an accommodating cavity 200 for storing water. The bung 140 is disposed on the bung 130, and the bung 130 extends inwardly from the bung 110 to connect the bung 110 and the bung 140 together. In addition, since the shoulder of the disposable vacuum refreshing soft barrel 100 is contracted, the distance between the connection position of the barrel shoulder 130 and the plurality of barrel side walls 111-116 and the central axis of the barrel 110 is greater than or equal to the distance between the trough end 1113 of the wavy corrugation 1111 and the central axis of the barrel 110, but less than or equal to the distance between the peak end 1112 of the wavy corrugation 1111 and the central axis of the barrel 110. This arrangement allows the shoulder 130 to be disposed obliquely to the barrel sidewalls 111-116, thereby allowing the shoulder of the soft, disposable vacuum refreshing barrel 100 to collapse to provide a smooth transition between the shoulder 130 and the barrel 110. In this embodiment, the connection between the shoulder 130 and the barrel sidewalls 111-116 is hexagonal. It is understood that the shape of the connection between the shoulder 130 and the plurality of barrel sidewalls 111-116 may be other shapes, which are determined by the sectional pattern of the prism surrounded by the plurality of barrel sidewalls 111-116. Specifically, an included angle θ between a tangent plane of a connection between the barrel shoulder 130 and the barrel side walls 111 to 116 corresponding to the connection ranges from 20 degrees to 70 degrees. Wherein the connection between the shoulder 130 and the plurality of barrel side walls 111-116 is located between the peak end 1112 and the valley end 1113 of the corrugated corrugation 1111. The purpose of setting the included angle between the tangent plane of the connection between the barrel shoulder 130 and the barrel side walls 111-116 corresponding to the connection between 20 degrees and 70 degrees is to: the shoulders 130 are disposed obliquely to the barrel sidewalls 111-116 to retract the shoulders of the soft disposable vacuum refreshing barrel 100. The disposable vacuum fresh-keeping soft barrel 100 is placed at the upper part of the water taking device when in use. That is, the weight of the disposable vacuum fresheners 100 enclosing the drinking water is applied to the shoulder 130 of the disposable vacuum fresheners 100. Therefore, the shape and strength of the shoulder 130 of the disposable vacuum refreshing soft barrel 100 are important. The inclined shape at the connection of the bucket shoulder 130 can enhance the strength of the bucket shoulder 130, and simultaneously avoid that when the area of the bucket shoulder 130 is too stretched, the stretching range of the polygonal prism corners transiting between the bucket shoulder 130 and the bucket body 110 is larger, so that the polygonal prism corners are whitened due to excessive stretching, and if serious, the disposable vacuum refreshing soft bucket 100 is damaged. In addition, since the shoulder of the disposable vacuum freshener drum 100 is contracted, the connection between the shoulder 130 and the plurality of drum sidewalls 111-116 is located between the peak end 1112 and the valley end 1113 of the wavy corrugation 1111. At this time, the distance between the connection point of the shoulder 130 and the plurality of barrel sidewalls 111-116 and the central axis of the barrel 110 is greater than or equal to the distance between the valley end 1113 of the wave-shaped corrugation 1111 and the central axis of the barrel 110, but less than or equal to the distance between the peak end 1112 of the wave-shaped corrugation 1111 and the central axis of the barrel 110. The above design may make the transition between the shoulder 130 and the barrel 110 smooth. In addition, since the shoulder 130 of the soft vacuum disposable bucket 100 is inwardly contracted, the lateral stretching ratio at the shoulder 130 is smaller than that at the barrel body 110 during the manufacturing process of the soft vacuum disposable bucket 100. As a result, more material accumulates in the shoulder 130 area during stretching, thereby increasing the thickness of the shoulder 130 area and thus increasing the strength of the shoulder 130. Specifically, the disposable vacuum refreshing soft tub 100 is manufactured through a blow molding process. In the blow molding process, factors influencing the thickness of the barrel body include the heating temperature of the blank body, the stretching ratio of the barrel body to the blank body and the like. Under the condition that other influence factors are unchanged, the larger the diameter of the barrel body is, the smaller the thickness of the barrel body is; the smaller the diameter of the barrel body is, the larger the thickness of the barrel body is. Therefore, in the present embodiment, since the shoulder 130 is obliquely contracted from the barrel 110 to the bung, the thickness of the shoulder 130 is greater than that of the barrel 110, so that the strength to the shoulder 130 is increased. The disposable vacuum refreshing soft barrel 100 may also be manufactured in other manners as required. At this time, the barrel thickness at the barrel shoulder 130 may also be directly greater than the barrel thickness at the barrel body 120 to enhance the strength of the barrel shoulder 130. Moreover, the shoulder 130 of the disposable vacuum freshener 100 is disposed to be inclined, and when the disposable vacuum freshener 100 is compressed to a position close to the limit, the inclined shoulder 130 can make the drinking water inside flow to the bung 140 more effectively. Meanwhile, as the barrel shoulder 130 is not easy to deform, when the disposable vacuum fresh-keeping soft barrel 100 is placed upside down on the water collector, the water guide core of the water collector can effectively push open the sealing cover of the disposable vacuum fresh-keeping soft barrel 100.

Specifically, the distance between the connection of the shoulder 130 and the

side wall

111, 113, 115 of the tub and the central axis of the tub 110 is substantially equal to the distance between the valley end 1113 of the wave-shaped corrugation 1111 in the

side wall

111, 113, 115 of the tub and the central axis of the tub 110. The distance between the connection of the shoulder 130 and the

side walls

112, 114, 116 of the tub body and the central axis of the tub body 110 is greater than the distance between the valley end 1113 of the undulated pleat 1111 and the central axis of the tub body 110 in the

side walls

112, 114, 116 of the tub body, but is smaller than the distance between the peak end 1112 of the undulated pleat 1111 and the central axis of the tub body 110. The shoulder 130 extends obliquely from the barrel sidewall 111-116 to the bung 140 location. That is, the distance between the shoulder 130 and the central axis of the barrel 110 gradually decreases from the peak end 1112 toward a direction away from the plurality of barrel sidewalls 111-116.

Specifically, the shoulder 130 includes several shoulder regions 131-136. The plurality of shoulder regions 131-136 are disposed in one-to-one correspondence with the plurality of barrel sidewalls 111-116. One or more of the several shoulder regions 131-136 is provided with a second reinforcement groove 1311-1361. The second reinforcement grooves 1311-1361 extend from the corresponding barrel sidewalls 111-116 to the bung 140, and the channel widths of the second reinforcement grooves 1311-1361 decrease from the barrel sidewalls 111-116 to the bung 140. In this embodiment, the second reinforcement slots 1311-1361 are disposed around the bung 140. The second reinforcing grooves 1311-1361 can reinforce the strength of the bucket shoulder 130, so as to avoid the situation that the bucket shoulder 130 is deformed due to excessive pressure bearing when the disposable vacuum refreshing soft bucket 100 is placed on a water taking device.

Each shoulder region 131-136 includes two second reinforcement grooves 1311-1361, as desired. Taking the shoulder region 131 as an example, it includes two second reinforcement grooves 1311. The second reinforcement groove 1311 includes a bottom edge 1312, a top edge 1213, and a first side edge 1314 and a second side edge 1315 disposed between the bottom edge 1312 and the top edge 1313. The bottom edge 1312 is disposed proximate to the bowl sidewall 111 and is substantially parallel to the bowl sidewall 111. The top edge 1313 is disposed proximate the bung 140. Specifically, the two second reinforcing grooves 1311 in the shoulder region 131 are symmetrically disposed, and a symmetry plane is a plane that passes through the central axis of the barrel 110 and is perpendicular to the barrel sidewall 111 corresponding to the shoulder region 131. Similarly, the shoulder region 132 includes two second reinforcement slots 1321; the shoulder region 133 includes two second stiffening grooves 1331; the shoulder region 134 includes two second stiffening channels 1341; the shoulder region 135 includes two second reinforcement grooves 1351; the shoulder region 136 includes two second stiffening channels 1361. The shape and arrangement of the second stiffening grooves 1321-1361 are similar to the second stiffening groove 1311 and will not be described again. In this embodiment, the second reinforcing grooves 1311-1361 are recessed inward from the shoulder regions 131-136, and a plurality of second rib structures 1316-1366 are formed in the receiving cavity 200 formed by the barrel 110, the bottom 120 and the shoulder 130. Specifically, flow guides 1317-1367 are formed between adjacent second fin structures 1316-1366. Projections of the first rib structures 1213-1263 in the axial direction of the tub 110 are located within projections of the flow guides 1317-1367 in the axial direction of the tub 110. That is, a projection of the first rib structure 1213 in the axial direction of the tub 110 is located within a projection of the flow guide 1317 in the axial direction of the tub 110; a projection of the first rib structure 1223 in the axial direction of the tub 110 is located within a projection of the flow guide 1327 in the axial direction of the tub 110; a projection of the first rib structure 1233 in the axial direction of the tub 110 is located within a projection of the guide part 1337 in the axial direction of the tub 110; a projection of the first rib structure 1243 in the axial direction of the tub 110 is located within a projection of the flow guide 1347 in the axial direction of the tub 110; a projection of the first bead structure 1253 in the axial direction of the tub 110 is located within a projection of the flow guide portion 1357 in the axial direction of the tub 110; a projection of the first rib structure 1263 in the axial direction of the tub 110 is located within a projection of the flow guide 1367 in the axial direction of the tub 110. The second reinforcement grooves 1311-1361 are disposed to be recessed inward from the shoulder 130, and a plurality of second rib structures 1316-1366 are formed in the receiving cavity 200 formed by the barrel body 110, the barrel bottom 120 and the shoulder 130, so as to: flow guides 1317-1367 may be formed between adjacent second fin structures 1316-1366. When the water amount in the disposable vacuum refreshing soft barrel 100 is less and less, the diversion parts 1317-1367 can more conveniently lead the drinking water out of the disposable vacuum refreshing soft barrel 100. In addition, since the projections of the first fin structures 1213 to 1263 in the axial direction of the tub 110 are located within the projections of the flow guides 1317 to 1367 in the axial direction of the tub 110. When the disposable vacuum fresheners cartridge 100 is compressed to the end, the first fin structures 1213-1263 can be inserted into the flow guides 1317-1367. In one aspect, the first rib structures 1213-1263 and the flow guides 1317-1367 are cooperatively arranged to increase the compressibility of the tub 110. On the other hand, when the first rib structures 1213-1263 are inserted into the diversion parts 1317-1367, the first rib structures 1213-1263 can squeeze the water flow inside the diversion parts 1317-1367, so that the drinking water in the disposable vacuum freshener 100 can flow out better to reduce the residual water in the disposable vacuum freshener 100. The first reinforcement grooves 121-126 have a length less than the second reinforcement grooves 1311-1361, as desired, so that the first rib structures 1213-1263 can be fully received within the flow guides 1317-1367 when the disposable vacuum refreshing soft tub 100 is under extreme compression.

As required, a holding portion 141 is disposed at a position of the barrel opening 140 close to the barrel shoulder 130. The grip portion 141 is recessed inward from an outer side surface of the bung 140. When the user lifts the disposable vacuum refreshing soft barrel 100, the holding part 141 on the barrel mouth 140 can provide a stress part for the user.

According to the requirement, the disposable vacuum fresh-keeping soft barrel 100 is made of one or more of PET (Polyethylene terephthalate), HDPE (high density Polyethylene), PP (polypropylene), PEN (Polyethylene naphthalate), PEF (Polyethylene furan dicarboxylate) and PPT (polypropylene naphthalate).

Referring to fig. 9, an embodiment of the present invention further provides a vacuum fresh-keeping water intake apparatus 300, which includes a vacuum fresh-keeping water intake apparatus 310 and the disposable vacuum fresh-keeping soft barrel 100 according to the above embodiment. The disposable vacuum fresh-keeping soft barrel 100 is arranged above the vacuum fresh-keeping water taking device 310.

Specifically, the vacuum fresh-keeping water intake device 310 includes a water guiding core 311. The bottom 120 of the disposable vacuum refreshing soft barrel 100 comprises a first concave part 129. The first recess 129 is provided at a middle region of the tub bottom 120. The first recess 129 includes a first arcuate recess region 1291 and a second arcuate recess region 1292. The radius of curvature of the first curved recessed region 1291 is greater than the radius of curvature of the second curved recessed region 1292. When the disposable vacuum refreshing soft barrel 100 is compressed until the first reinforcing grooves 121-126 contact with the barrel shoulder regions 131-136, the distance between the end of the water guiding core 311 and the lowest end of the second arc-shaped recessed region 1292 is greater than zero. When the disposable vacuum refreshing soft barrel 100 is compressed to the point that the first reinforcing grooves 121-126 are in contact with the barrel shoulder regions 131-136, the distance between the end of the water guiding core 311 and the lowest end of the second arc-shaped concave region 1292 is set to be greater than zero, so that: when the disposable vacuum fresh-keeping soft barrel 100 is compressed to the limit, the water guiding core 311 of the vacuum fresh-keeping water collector 310 does not prop against the barrel bottom 120, so that the barrel body 110 cannot be compressed any more.

The vacuum fresh-keeping water collector 310 may be the vacuum fresh-keeping water collector described in the patent application with application number 2020106966560.0 (publication number: CN 111794313A) filed by the applicant on 7, 17.2020 and year, according to requirements.

In the actual working process, after the disposable vacuum fresh-keeping soft barrel 100 is filled with the drinking water, a sealing cover 320 may be disposed at the barrel mouth 140 of the disposable vacuum fresh-keeping soft barrel 100 to seal the disposable vacuum fresh-keeping soft barrel 100. When in use, the disposable vacuum fresh-keeping soft barrel 100 is placed on the water collector 310. The water guiding core 311 of the water collector 310 pushes open the inner wall of the cylinder body in the sealing cover 320, so that the drinking water enters the water collector 310 from the water guiding hole 312 on the water guiding core 311. The sealing cover 320 is in sealing connection with the water guide core 311, so that when the disposable vacuum fresh-keeping soft barrel 100 is used, air cannot enter the interior of the disposable vacuum fresh-keeping soft barrel 100, and therefore the water quality of drinking water in the interior of the disposable vacuum fresh-keeping soft barrel 100 is kept fresh. The water collector 310 further comprises a water collector tray 330, and the bucket shoulder 130 of the disposable vacuum refreshing soft bucket 100 is placed on the water collector tray 330.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
