In response to the problem of insufficient cleaning force of the rotating brush on the existing cleaning machine, a first embodiment of the present utility model provides a cleaning mechanism comprising a drive assembly 20 and a cleaning assembly 30. Referring to fig. 1, the cleaning assembly 30 includes a support plate 31 and a flexible cleaning member 32. The supporting plate 31 is connected with the driving assembly 20 and is inclined to the surface to be cleaned (such as ground, desktop, wall surface, etc.), the flexible cleaning member 32 is paved on one side of the supporting plate 31 far away from the driving assembly 20, and the driving assembly 20 drives the supporting plate 31 to drive the flexible cleaning member 32 to rotate, so that the cleaning assembly 30 can complete the cleaning work of the surface to be cleaned in the rotating process. Because the cleaning component 30 in the rotary cleaning work is inclined to the surface to be cleaned, the cleaning force of the cleaning component 30 on the surface to be cleaned can be reduced, and the cleaning force of the cleaning component 30 on the surface to be cleaned can be improved, so that the cleaning component 30 can remove stubborn stains with high efficiency.

Wherein the flexible cleaning member 32 has a cleaning portion 321 away from the support plate 31, and a cross section of the cleaning portion 321 is gradually reduced in a direction parallel to the support plate 31 in a direction away from the support plate 31, a surface of the cleaning portion 321 away from the support plate 31 will be at least in contact with a surface to be cleaned, thereby improving cleaning efficiency of the surface to be cleaned.

As can be seen, in the cleaning mechanism provided in the present embodiment, the supporting plate 31 of the cleaning assembly 30 is connected with the driving assembly 20 and is inclined to the surface to be cleaned, and the flexible cleaning member 32 is disposed on a side of the supporting plate 31 away from the driving assembly 20, so that the supporting plate 31 drives the flexible cleaning member 32 to rotate under the driving of the driving assembly 20. Since the supporting plate 31 is inclined to the surface to be cleaned, the flexible cleaning member 32 can be inclined to the surface to be cleaned under the supporting action of the supporting plate 31, the surface area of the cleaning assembly 30 is reduced, and the pressure applied to the surface to be cleaned per unit area of the cleaning assembly 30 is increased. Therefore, in the process that the supporting plate 31 drives the flexible cleaning member 32 to rotate for cleaning, the supporting plate 31 can apply larger cleaning force to the surface to be cleaned through the flexible cleaning member 32, so that the cleaning effect of the surface to be cleaned is improved, and the smooth cleaning of stubborn stains is realized. Second, while the support plate 31 applies a large cleaning force to the surface to be cleaned through the flexible cleaning member 32, since the cross-sectional area of the cleaning portion 321 is gradually reduced in a direction away from the support plate 31, at least a portion of the surface of the cleaning portion 321 away from the support plate 31 can be in contact with the surface to be cleaned, and the cleaning area of the surface to be cleaned by the flexible cleaning member 32 is increased to further increase the cleaning efficiency of the cleaning assembly 30 in the inclined state.

Therefore, the cleaning device of the present embodiment can clean the surface to be cleaned with a larger cleaning area and a larger cleaning force, so that the cleaning efficiency and the cleaning effect of the inclined cleaning assembly 30 are both higher, and the cleaning efficiency is not lower than that of the ground-attached planar rotary brush. The cleaning portion 321 of the flexible cleaning member 32 has a certain thickness in a direction away from the support plate 31, so that the contact area between the surface of the cleaning portion 321 and the surface to be cleaned can be increased under the condition that the cross-sectional area of the cleaning portion 321 is gradually reduced in the direction away from the support plate 31, thereby realizing efficient cleaning of the surface to be cleaned.

The flexible cleaning elements 32 in this embodiment may be mops, glue brushes, sponge brushes, etc. When the flexible cleaning member 32 is a mop, the cleaning portion 321 is a portion of the mop away from the support plate 31, so that the cleaning efficiency of the cleaning mechanism provided in the present embodiment is improved by the contact of the cleaning portion 321 of the mop with the surface to be cleaned.

The cleaning portion 321 has a circular cross section in a direction parallel to the support plate 31. Therefore, in the process that the supporting plate 31 drives the flexible cleaning member 32 to rotate, the friction resistance between the cleaning part 321 and the surface to be cleaned can be reduced, so that the cleaning part 321 of the flexible cleaning member 32 can rotate rapidly to realize efficient cleaning of the surface to be cleaned.

In the present embodiment, the cleaning portion 321 has an isosceles trapezoid cross section in the axial direction thereof in the direction perpendicular to the support plate 31. That is, the cleaning portion 321 is a cylindrical structure with a gradually decreasing cross-sectional area, and since the cross-section of the cleaning portion 321 along the direction perpendicular to the supporting plate 31 is isosceles trapezoid, in the process that the cleaning portion 321 rotates with the flexible cleaning member 32, a larger contact area is provided between each portion of the outer peripheral surface of the cleaning portion 321 and the surface to be cleaned, and the contact areas are the same, so that the cleaning efficiency is higher.

Specifically, a first included angle (the first included angle is an angle denoted by a symbol α in fig. 1) is formed between the supporting plate 31 and the surface to be cleaned, and the first included angle is greater than 0 ° and less than 45 °. Thereby ensuring that the support plate 31 can apply a large cleaning force to the flexible cleaning member 32 in an inclined state. The first included angle may specifically include one of 3 °,4 °, 5 °, 8 °, 13 °, 15 °, 20 °, 24 °, 26 °, 28 °, 30 °, 32 °, 35 °, 37 °, 38 °, 40 °, 41 °, 43 °, 45 °, and the like. The preferred angle of the first included angle of this embodiment is 5 ° in combination with the spatial layout and cleaning effect on the cleaning apparatus body 10. That is, when the first included angle is 5 °, the cleaning force of the cleaning assembly 30 is ensured to be large, the cleaning effect is good, and the volume of the cleaning mechanism is not increased, so that the assembly difficulty of the cleaning mechanism on the cleaning device is reduced.

The second embodiment of the present utility model also provides a cleaning apparatus, referring to fig. 2 to 7, which includes a body 10, a cleaning tray 40, and a cleaning mechanism according to the first embodiment of the present utility model. The cleaning tray 40 is connected to the body 10, and a cleaning chamber is defined between the cleaning tray and the body 10. The drive assembly 20 of the cleaning mechanism is disposed in the body 10, and the cleaning assembly 30 of the cleaning mechanism is at least partially disposed in the cleaning chamber so that the cleaning tray 40 cleans the cleaning assembly 30.

The supporting plate 31 of the cleaning assembly 30 is connected with the driving assembly 20 and is inclined to the surface to be cleaned, the flexible cleaning member 32 is paved on one side of the supporting plate 31 far away from the driving assembly 20, and the driving assembly 20 drives the supporting plate 31 to drive the flexible cleaning member 32 to rotate, so that the cleaning assembly 30 can complete the cleaning work of the surface to be cleaned in the rotating process. Because the cleaning component 30 in the rotary cleaning work is inclined to the surface to be cleaned, the cleaning force of the cleaning component 30 on the surface to be cleaned can be reduced, the cleaning force of the cleaning equipment on the surface to be cleaned can be improved, and the cleaning component 30 can remove stubborn stains with high efficiency.

Therefore, in the cleaning apparatus provided in this embodiment, the cleaning assembly 30 is inclined to the surface to be cleaned, and in the process of driving the cleaning assembly 30 to rotate by the driving assembly 20 to clean the surface to be cleaned, the area of the cleaning assembly 30 can be reduced, the pressure applied to the surface to be cleaned by the cleaning assembly 30 per unit area can be increased, the cleaning force of the cleaning assembly 30 can be greatly increased, and the cleaning of stubborn stains can be smoothly achieved. Next, a cleaning tray 40 is connected to the cleaning apparatus body 10, and a cleaning chamber is defined between the cleaning tray 40 and the cleaning apparatus body 10. During rotation of the cleaning assembly 30 for cleaning, portions of the cleaning assembly 30 are continually rotated into the cleaning chamber to self-clean the flexible cleaning elements 32. Therefore, the cleaning device can complete the cleaning operation of the cleaning assembly 30 in the cleaning process without returning to the base station, so that the cleaning efficiency of the cleaning assembly 30, the cleaning effect and the cleaning capability of the surface to be cleaned are improved, and the surface to be cleaned is cleaner and tidier.

As shown in fig. 3 and 5, a cleaning tank 41 is disposed on one side of the cleaning tray 40 near the main body 10, and a cleaning chamber is defined between the cleaning tank 41 and the main body 10. It can be seen that, in this embodiment, the cleaning tray 40 is connected to the main body 10, so as to obtain a cleaning chamber for cleaning the cleaning assembly 30, and the assembly is efficient and convenient. And an opening 42 through which the cleaning assembly 30 passes is provided on one side of the cleaning tank 41 adjacent to the cleaning assembly 30. In the process of driving the cleaning assembly 30 to rotate by the driving assembly 20, the cleaning assembly 30 can penetrate into the cleaning chamber through the opening 42 to clean, and the part of the cleaning assembly 30 outside the cleaning chamber is responsible for cleaning the surface to be cleaned, so that the purpose of self-cleaning the flexible cleaning member 32 while cleaning the surface to be cleaned is achieved. Compared with the prior art that the base station cleans the flexible cleaning member 32 and then returns to the base station to clean the surface to be cleaned, the cleaning efficiency is higher, and the flexible cleaning member 32 always keeps in a cleaner state in the cleaning process, so that the cleaning effect of the flexible cleaning member 32 on the surface to be cleaned is better.

In some embodiments of the present utility model, the body 10 of the cleaning apparatus may include a main body portion 11, a mounting portion 12, and a grip portion 13. The main body 11 is connected to the grip 13 via the attachment 12, and an attachment chamber is provided in the main body 11. The driving assembly 20 may include a driving portion and a rotating shaft 23, the driving portion is disposed in the mounting cavity, one end of the rotating shaft 23 is connected with the driving portion, and the other end extends out of one end of the main body 11 far away from the holding portion 13 to be connected with the cleaning assembly 30, and the driving portion drives the rotating shaft 23 to drive the cleaning assembly 30 to rotate. The rotating shaft 23 is perpendicular to the supporting plate 31 when connected with the supporting plate 31 of the cleaning assembly 30, so as to drive the supporting plate 31 to rotate. The end surface of the main body 11 far away from the end of the holding portion 13 may enclose with the cleaning tank 41 of the cleaning tray 40 to form a cleaning chamber, so that the cleaning assembly 30 can continuously enter the cleaning chamber for cleaning during rotation, thereby improving the cleaning degree of the cleaning assembly 30 during cleaning and further improving the cleaning effect of the surface to be cleaned.

When the angle of the first included angle between the support plate 31 of the cleaning assembly 30 and the surface to be cleaned is large, such as one of 20 °, 24 °, 26 °, 28 °, 30 °, 32 °, 35 °, 37 °, 38 °, 40 °, 41 °, 43 °, 45 °, etc. Since the driving part mainly comprises the motor 21 and the gear box 22, the motor 21 and the gear box 22 have relatively large volumes, and if the driving part is obliquely installed in the body 10 to ensure that the cleaning assembly 30 can be obliquely installed at a large angle, a large installation cavity space is occupied, and certain difficulties are brought to the design and installation of the body 10 and the driving part. In this regard, the present embodiment can save the layout space occupied by the driving assembly 20 in the main body 11 by providing a transmission member between the driving portion and the cleaning assembly 30. At this time, the rotating shaft 23 in the present embodiment includes a first shaft section and a second shaft section, the first shaft section is located in the body 10 and connected with the driving portion, and the first shaft section is specifically located in the mounting cavity of the main body 11 to be connected with the driving portion. One end of the second shaft section positioned in the body 10 is in transmission connection with the first shaft section through a transmission part, the first shaft section and the second shaft section form a second included angle, the other end of the second shaft section is positioned in the cleaning chamber and is connected with the supporting plate 31, and the driving part drives the first shaft section to drive the second shaft section to rotate. Therefore, in this embodiment, the rotating shaft 23 with smaller volume is split into the first shaft section and the second shaft section, when the first shaft section and the second shaft section are connected through the transmission component, the first shaft section and the second shaft section form the second included angle, and at this time, the installation angle of the driving assembly 20 in the main body 11 can be kept at a smaller angle, so that the cleaning assembly 30 can be inclined at a larger angle through the set second included angle. The driving part installation angle is prevented from being too large to bring additional production cost to the main body part 11 of the body 10, or the cost and inconvenience brought by redesigning the driving part to adapt to the space size of the installation cavity of the main body part 11. If the first included angle of the cleaning assembly 30 is required to be 24 °, the driving portion may still maintain a mounting angle of 5 ° or even less than 5 ° in the mounting cavity, and the second included angle may be set to one of 19 °, 20 °, 21 °, etc.

Wherein the transmission member may include a first bevel gear and a second bevel gear. The first bevel gear is connected to an end of the first shaft section remote from the drive portion, and the second bevel gear is connected to an end of the second shaft section remote from the cleaning assembly 30 and is meshed with the first bevel gear. In the embodiment, when the first bevel gear and the second bevel gear are used for realizing transmission connection of the first shaft section and the second shaft section, the meshing relationship between the first bevel gear and the second bevel gear is utilized to enable the first shaft section and the second shaft section to form a second included angle, so that the space of an installation cavity in the main body part 11 is saved, and the cleaning assembly 30 can be ensured to have a larger inclination angle under the drive of the second shaft section.

The tank bottom of the cleaning tank 41 is provided with a cleaning flow channel 43, one side of the cleaning flow channel 43 along the width direction is provided with a water scraping part 430, at least one of clean water, cleaning liquid and the like can be introduced into the cleaning flow channel 43 to wet and clean the flexible cleaning member 32, the water scraping part 430 is in interference fit with the flexible cleaning member 32, so that sewage and dirt on the flexible cleaning member 32 are scraped into the cleaning flow channel 43 through the water scraping part 430 in the rotating process of the flexible cleaning member 32, the flexible cleaning member 32 always keeps good cleanliness, and the scraped sewage and dirt are discharged through the cleaning flow channel 43.

As shown in fig. 5, the cleaning tray 40 is further provided with a first opening 44 and a second opening 45, and the cleaning flow path 43 has one end communicating with the first opening 44 and the other end communicating with the second opening 45. In this embodiment, clean water, cleaning liquid, etc. can be introduced into the cleaning flow channel 43 through the first opening 44, and the second opening 45 is used as a dirt suction port to discharge the sewage, garbage, etc. cleaned from the flexible cleaning member 32 out of the cleaning flow channel 43. The wiper 430 may be specifically disposed on a side of the cleaning flow channel 43 near the second opening 45, so that when the flexible cleaning member 32 is in interference fit with the wiper 430 of the cleaning flow channel 43 near the second opening 45, the wiper 430 scrapes the sewage and dirt on the flexible cleaning member 32 to one end of the cleaning flow channel 43 near the second opening 45, so as to timely discharge the dirt through the second opening 45, thereby reducing or even avoiding the dirt deposited on the cleaning flow channel 43, and improving the cleaning effect of the cleaning assembly 30. For stubborn stains such as carbonized greasy dirt, the flexible cleaning member 32 can be cleaned by introducing hot water or cleaning liquid into the first opening 44, so that the cleaning effect of the flexible cleaning member 32 is improved.

The bottom of the washing chamber, which is remote from the body 10 (i.e., the bottom of the washing tub 41), is further provided with a first boss 46, and the first opening 44 and the second opening 45 are located at opposite sides of the first boss 46, respectively. The length of the purge flow channel 43 extends along the outer periphery of the first boss 46 from the first opening 44 to the second opening 45. At this time, the wiper 430 may be specifically disposed on a side of the first boss 46 near the second opening 45, so as to timely scrape dirt and sewage into the cleaning flow channel 43 near the second opening 45. Specifically, as shown in fig. 5, the wiper 430 may be disposed on a side of the first boss 46 near the cleaning flow channel 43 and located at the second opening 45, so as to facilitate scraping dirt and sewage into the cleaning flow channel 43 and timely discharging the dirt and sewage from the second opening 45.

As shown in fig. 5, the bottom of the cleaning chamber far away from the body 10 is further provided with a second boss 47, the second boss 47 protrudes from the surface of the first boss 46 and is located at one side of the first boss 46, which is dislocated from the cleaning flow channel 43, and the first opening 44 and the second opening 45 are arranged on the second boss 47 at intervals, so that the processing difficulty of the cleaning tray 40 is reduced. Specifically, the cleaning tray 40 may be connected to the mounting portion 12 of the cleaning apparatus through the second boss 47, and at this time, a liquid inlet channel communicating with the first opening 44 and a dirt suction channel communicating with the second opening 45 are provided in the mounting portion 12. In the mounting process, the first opening 44 and the second opening 45 on the second boss 47 are arranged corresponding to the liquid inlet flow channel and the sewage pumping flow channel respectively. Clean water and cleaning liquid can be conveyed to the first opening 44 along the liquid inlet channel in the mounting part 12 to enter the cleaning channel 43, and dirt and sewage can be pumped out along the dirt pumping channel from the second opening 45 through the dirt pumping channel.

The purge flow path 43 in this embodiment includes a first flow path section 431 and a second flow path section 432. The second flow path section 432 is closer to the second opening 45 than the first flow path section 431 and is communicated with the second opening 45, and the width of the second flow path section 432 is larger than that of the first flow path section 431 along the rotation direction of the cleaning component 30, so that the stains and sewage can be discharged from the second flow path section 432 through the second opening 45 quickly, and the stains are prevented from being deposited on the first flow path section 431 or the second flow path section 432. As shown in fig. 5, the water scraping portion 430 is specifically disposed on a side of the first boss 46 near the second flow path section 432, so as to scrape dirt and sewage into the second flow path section 432 and timely discharge the dirt from the second opening 45, so as to avoid the dirt from being deposited in the cleaning flow path 43.

The width of the second channel section 432 in the direction of rotation of the cleaning assembly 30 increases gradually in a direction approaching the second opening 45 so that dirt can be quickly washed into the second channel section 432 and discharged from the second opening 45 along the second channel section 432. A first space is provided between the bottom of the first flow path section 431 and the apex of the first boss 46, and a second space is provided between the bottom of the second flow path section 432 and the apex of the first boss 46, the first space being smaller than the second space. Namely, the highest water level point of the cleaning flow channel 43 is positioned on the first flow channel section 431, and the lowest water level point is positioned on the second flow channel section 432, so that clean water, cleaning liquid and the like can flow from the first flow channel section 431 with the highest water level to the second flow channel section 432, and the dirt and sewage can be discharged from the second flow channel section 432 while the cleaning assembly 30 is cleaned efficiently.

The cleaning tray 40 provided in this embodiment may specifically be a structure having only one second opening 45 as shown in fig. 5, and the cleaning tray 40 may also be a structure having two second openings 45 as shown in fig. 6 and 7. When the number of the second openings 45 of the cleaning tray 40 is two, the dirt sucking operation can be performed simultaneously through the two second openings 45, so that the dirt sucking efficiency is improved, and the cleaning effect of the cleaning tray 40 on the cleaning assembly 30 is further improved. The first opening 44 and the two second openings 45 are disposed on the second boss 47, and the first opening 44 is located between the two second openings 45, and the first flow channel section 431 is disposed on the first boss 46 and is in communication with the first opening 44. The second flow path section 432 extends from one of the second openings 45 to the other second opening 45 along the outer periphery of the first boss 46. The two ends of the second flow channel section 432 close to the second opening 45 are the lowest water level points of the cleaning flow channel 43, the highest water level points are located on the first flow channel section 431, and the distance from the bottom of the first flow channel section 431 to the top of the first boss 46 can be gradually increased along the direction away from the first opening 44, so that clean water, cleaning liquid and the like can better flow into the second flow channel section 432. The wiper portion 430 may be disposed on a side of the second flow path segment 432 that is remote from the first boss 46 and proximate to one of the second openings 45 (as shown in fig. 6). The cleaning assembly 30 rotates to the end of the second flow channel section 432 where the water scraping part 430 is not arranged, then rotates to the end of the second flow channel section 432 where the water scraping part 430 is arranged to scrape water, so that sewage and stains can be conveniently scraped into the second flow channel section 432, and can be timely discharged through the second opening 45, so that the dirt deposited in the second flow channel section 432 is reduced, and the cleaning effect on the flexible cleaning member 32 is improved.

When the cleaning tray 40 is of the structure shown in fig. 6 and 7, the first flow path section 431 provided on the first boss 46 divides the first boss 46 into a first land 461 and a second land 462. The first and second mesas 461 and 462 are each inclined in a direction approaching the bottom of the second flow path section 432 so that the clean water, cleaning liquid, etc. overflowed from the first flow path section 431 can enter the second flow path section 432 along the first and second mesas 461 and 462, clean the first and second mesas 461 and 462, and then timely discharge the cleaned sewage along the second flow path section 432 through the corresponding two second openings 45.

The flexible cleaning member 32 of the present embodiment is interference fit with the cleaning tank 41 to close the cleaning flow path 43. After the cleaning flow channel 43 is sealed, the cleaning device can be used perpendicular to a surface to be cleaned, for example, when the cleaning device is used for cleaning a vertical surface such as a wall surface, clean water or sewage in the cleaning flow channel 43 is not easy to overflow, and the cleaning device is convenient to use and good in user experience. When the flexible cleaning member 32 is a mop, the cleaning chamber cooperates with a mop of appropriate interference to prevent the clean water or dirty water from the cleaning channel 43 from escaping.

The flexible cleaning member 32 in this embodiment is provided with the avoiding hole 322, so that friction resistance between the flexible cleaning member 32 and the cleaning tray 40 is reduced through the avoiding hole 322, and smooth rotation of the flexible cleaning member 32 is ensured to perform cleaning and self-cleaning. The avoiding hole 322 may penetrate or not penetrate the flexible cleaning member 32 in a direction approaching the support plate 31, so long as friction between the flexible cleaning member 32 and the cleaning chamber can be reduced, and the present embodiment is not limited only herein.

It can be seen that, in this embodiment, while the flexible cleaning member 32 and the cleaning chamber have a larger interference to close the cleaning flow channel 43, the friction between the flexible cleaning member 32 and the cleaning chamber is reduced by the avoiding hole 322, so as to improve the self-cleaning efficiency of the flexible cleaning member 32 and the cleaning efficiency and effect of cleaning the surface to be cleaned. The avoidance hole 322 may be specifically provided at the middle of the flexible cleaning member 32, so that at least a portion of the outer circumferential surface of the cleaning portion 321 of the flexible cleaning member 32 can be in contact with the surface to be cleaned, thereby improving cleaning efficiency.

Therefore, the present embodiment can reduce the floor area of the cleaning assembly 30 by tilting the cleaning assembly 30 (commonly called a rotating brush), thereby greatly improving the cleaning force of the cleaning assembly 30. Meanwhile, the cleaning efficiency of the inclined cleaning assembly 30 is not lower than that of the planar rotary brush by designing the flexible cleaning member 32 with a trapezoidal structure in cross section. In addition, by providing the cleaning tray 40, the self-cleaning requirements of the cleaning assembly 30 are met, enhancing cleaning ability.

A third embodiment of the present utility model provides a base station, which includes a cleaning device, and the structure of the cleaning device is specifically referred to the content provided in the second embodiment of the present utility model, and this embodiment is not described herein again.
