Detailed ways

The implementation of the utility model will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and implement the implementation process of how to apply technical means to solve technical problems and achieve corresponding technical effects in the utility model. The embodiments of the utility model and the various features in the embodiments can be combined with each other under the premise of not conflicting, and the formed technical solutions are all within the protection scope of the utility model.

The liquid supply device of the embodiment of the utility model is mainly used to provide heated liquid (mainly water), including a liquid container, a one-way sealing member that allows the liquid to enter the liquid container, and a heating device that is mainly used to heat the liquid container. source. The liquid container is provided with a liquid inlet and a liquid outlet, and the one-way sealing member controls liquid to enter the liquid container through the liquid inlet on the liquid container. When the one-way sealing member is opened, the liquid enters the liquid container through the liquid inlet. When the one-way sealing member is closed, the liquid cannot reversely flow out of the liquid container through the liquid inlet. The one-way sealing member may be, for example, a one-way valve. When the liquid container contains liquid (such as water), the heating source is mainly used to heat the liquid in the liquid container.

When the one-way sealing member is opened, the external liquid enters into the liquid container through the liquid inlet. Since the liquid outlet of the liquid container is open, the pressure of the liquid container is equal to that of the external environment (the external space relative to the inside of the liquid container). Close the liquid inlet of the liquid container, and use the heating source to heat the liquid container, and the liquid container will transfer the heat to the liquid therein. As the liquid is heated, the temperature of the liquid in the liquid container gradually rises. During this process, the liquid in the liquid container will generate a small amount of vapor, and the pressure of the liquid container and the external environment will remain roughly equal.

For a liquid container with a small volume, an exhaust port is also arranged on it. Usually, the liquid container is not filled to the brim, and there is still a certain amount of free space. As the temperature of the liquid in the liquid container gradually rises, the internal pressure of the liquid container will gradually increase. In order to continue to maintain the pressure balance inside and outside the liquid container, the gas in the empty space in the liquid container will be discharged from the exhaust port of the liquid container. The vent port on the liquid container may be a vent valve or a vent hole connecting the interior of the liquid container with the external environment. For larger liquid containers, an exhaust port may or may not be provided.

As the heating source continues to heat the liquid in the liquid container, the temperature of the liquid in the liquid container continues to rise, and the internal pressure of the liquid container will also continue to increase. In order to continue to maintain the pressure balance inside and outside the liquid container, the gas discharged from the vent port of the liquid container will be accelerated. Until the gas generated by heating in the liquid container is difficult to be discharged from the exhaust port in time, such as when the exhaust valve is automatically closed or the exhaust hole cannot discharge all the gas generated by heating in the liquid container in time, the liquid container The heated liquid will pass through the liquid outlet of the liquid container and be pressed out of the liquid container.

A safety valve can also be arranged on the liquid container. When the air pressure inside the liquid container exceeds the safe air pressure, the safety valve will be opened to release the pressure, effectively preventing the possible explosion hazard caused by the high air pressure in the liquid container. For example, under abnormal conditions such as a blockage of the liquid outlet pipe or a slow liquid outlet speed, as the heating source continues to heat, the air pressure in the liquid container will gradually increase. The existence of the safety valve can effectively avoid the danger that the heating source continues to heat and the air pressure in the liquid container is too high. Typically, a safety valve can be located adjacent to the exhaust port. For example, the safety valve and the exhaust port are adjacently arranged on the top of the liquid container.

In the embodiments of the present application, the heating source can be a heating plate, a heating pot, a heating rod extending into the liquid container, a heating tube connected to the liquid container, or even these Various combinations of heating elements. For the heating plate, it is usually arranged at the bottom of the liquid container; for the heating pot, it is usually arranged at the bottom of the liquid container or around the liquid container, which is convenient for evenly heating the liquid in the liquid container. The heating tube is usually arranged outside the liquid container and communicated with the liquid container, such as a U-shaped tube, and the like. The typical setting methods are described above by taking various common heating devices as examples. In fact, it is feasible that the heating source is partly located inside the liquid container, partly outside the liquid container, or even embedded in the wall of the liquid container, as long as it can directly heat the liquid in the liquid container, or pass through the liquid container. It is feasible to heat the liquid in the liquid container by heat conduction.

The heating tube communicates with the liquid container, and at least part of the liquid entering the liquid container through the liquid inlet will enter the heating tube. By heating the liquid flowing into the heating tube, and the convection and circulation of the liquid in the heating tube and the liquid in the liquid container, the entire liquid in the heating container can be heated finally.

In some embodiments, a liquid outlet tube is also connected to the liquid outlet. The first end of the liquid outlet pipe extends into the liquid container, and the second end provides an outlet for the liquid. Certainly, the first end of the liquid outlet pipe may not protrude into the liquid container. A certain amount of liquid is injected into the liquid container through the one-way sealing member, and then the one-way sealing member is closed to heat the liquid in the liquid container through the heating source, a part of the liquid is heated and vaporized, and the gas is exhausted The pressure of the whole container is equivalent to that of the external environment. As the liquid in the liquid container continues to be heated, the temperature of the liquid in the container increases and the gasification intensifies, and the exhaust valve closes (or the exhaust hole cannot discharge all the generated steam in time), the pressure in the container will make the liquid in the container The hot water is pressed out of the machine through the outlet pipe to brew beverages.

As shown in FIG. 1 , the liquid supply device of the embodiment of the present invention mainly includes a liquid container 1 , and the liquid inlet 14 of the liquid container 1 is provided with a one-way valve 2 that can inject external liquid into the liquid container 1 . The one-way valve 2 allows external liquid, such as water, to flow into the liquid container 1 in the direction of entering the liquid container 1 , but does not allow the liquid in the liquid container 1 to flow out of the liquid container 1 through the one-way valve 2 .

The liquid outlet pipe 3 extends into the liquid container 1 through the liquid outlet 15 of the liquid container 1 .

Typically, liquid can enter the liquid container 1 through the one-way valve 2 . That is, when the liquid supply device or the product containing the liquid supply device is placed naturally, the one-way valve 2 is usually located above the liquid level of the liquid container 1 filled with water or other liquids. In this way, the liquid enters the liquid container 1 by its own gravity or partly by its own gravity, which can reduce the difficulty and implementation cost of liquid entering the liquid container 1 . As shown in Figure 1, when the liquid supply device or the product containing the liquid supply device is placed naturally, the one-way valve 2 is arranged at the highest position of the liquid container 1 (of course, it is also feasible to be arranged at a higher position of the liquid container 1 ). If there is no special statement, the following descriptions will be made by taking the case where the liquid supply device or the product containing the liquid supply device is placed naturally as an example.

The liquid supply device of the embodiment shown in FIG. 1 further includes a heating tube 4 located outside the liquid container 1 and used for heating the liquid in the liquid container 1 . The heating tube 4 has a first port 41 and a second port 42 . The heating tube 4 communicates with the liquid container 1 through the first port 41 and the second port 42 . Preferably, the part where the liquid container 1 is connected to the heating tube 4, that is, the part where the liquid container 1 is connected to the first port 41 and the second port 42 of the heating tube 4, is located where the liquid supply device is naturally placed or contains The product of the liquid supply device and the position below the liquid surface when the liquid container 1 is filled with liquid.

As shown in FIG. 1 , the part where the liquid container 1 is connected to the first port 41 of the heating tube 4 is the first interface 11 , and the part that is connected to the second port 42 of the heating tube 4 is the first interface 12 . When the liquid supply device or the product containing the liquid supply device is placed naturally, both the first interface 11 and the second interface 12 are located at the lowest part of the liquid container 1 . The liquid, such as water, entering the liquid container 1 through the one-way valve 2 will automatically enter the heating tube 4 under the action of gravity.

The liquid outlet pipe 3 is tightly connected with the liquid outlet 15 of the liquid container 1 . When the liquid supply device or the product containing the liquid supply device is placed naturally, the first end 31 of the liquid outlet pipe 3 extends into a deeper position in the liquid container 1, and is closer to the bottom wall of the liquid container 1, which is convenient for the liquid container. When the liquid in 1 is less, it can also be discharged to the outside through the liquid outlet pipe 3.

The second end 32 of the outlet pipe 3 can be inserted into the raw material container 9 . Powder and/or granular food materials are contained in the raw material container 9, which is convenient for brewing into beverages. Of course, it is also feasible that the second end 32 of the liquid outlet pipe 3 is configured as an open structure.

As shown in Figure 1, the liquid container 1 is configured with a low-lying area 13, which is lower than other parts of the liquid container 1, so as to ensure that the liquid can be preferentially accumulated in the low-lying area after the liquid container 1 is filled with the heating tube 4 13. After filling the low-lying area 13, the liquid container 1 can also be filled with a relatively large amount of liquid. The first end 31 of the liquid outlet pipe 3 protrudes into the bottom wall of the liquid container 1 and is close to the depression 13 .

The bottom of the liquid container can also be configured as a non-parallel slope with the horizontal plane (the horizontal plane formed when a certain amount of water is filled in the liquid container), or a part thereof is configured with a non-parallel slope with the horizontal plane. For liquid containers of this shape and structure, the lowest position of the slope is the low-lying area.

As shown in FIG. 1 , the liquid container 1 is also provided with a safety valve 5 and an exhaust valve 6 . Preferably, the exhaust valve 6 is arranged on the top wall of the liquid container 1 . When the liquid container 1 was just beginning to be heated, the exhaust valve 6 ensured that the pressure of the liquid container 1 was equal to the external environment, and the gas in the liquid container 1 mainly entered the external environment from the exhaust valve 6 earlier (a small amount would pass through the liquid outlet 3 into the external environment). As the heating time prolongs, the internal air pressure of the liquid container 1 increases gradually, and the speed of the gas ejected from the exhaust valve 6 also increases. Until the pressure generated by the air pressure difference between the inside of the liquid container 1 and the external environment acts on the exhaust valve 6, when it is greater than the gravity of the exhaust valve 6, the exhaust valve 6 will be closed, so that the gas in the liquid container 1, And the heated liquid can only enter the external environment through the liquid outlet pipe 3 . The exhaust valve 6 ensures that the liquid in the liquid container 1 will not flow out of the liquid container when it is heated at the beginning; only after being heated to a certain temperature, it will be pressed out from the liquid container 1 and used to prepare beverages . The exhaust valve 6 in the embodiment shown in Figure 1 can also be replaced by an exhaust hole. During the heating process, although the exhaust hole will not be closed, the liquid in the liquid container is continuously heated to a certain degree, and the liquid container Most of the gas generated by heating in 1 and the heated liquid will also enter the external environment through the outlet pipe 3 to prepare beverages, and only a small amount of gas generated by heating will be discharged from the vent hole to the external environment.

FIG. 1 shows a state of waiting for liquid (such as water) to be introduced into the liquid supply device. In this state, the one-way valve 2 and the exhaust valve 6 are opened, and the safety valve 5 is closed. External water enters the liquid container 1 through the one-way valve 2 .

Fig. 2 shows that an appropriate amount of water has been injected into the liquid supply device and the heating tube 4 is in a heating state. In this state, the one-way valve 2 and the safety valve 5 are closed, and the exhaust valve 6 is opened. The temperature of the water in the liquid container 1 increases gradually under the heating effect of the heating tube 4 . As the heating time increases, at least a portion of the water will be heated to a gaseous state. As the heating time of the heating tube 4 continues to prolong, the pressure in the liquid container 1 will continue to rise.

FIG. 3 shows a state in which an appropriate amount of water injected into the liquid supply device has been heated and the water is discharged through the liquid outlet pipe 3 . In this state, the one-way valve 2, the safety valve 5 and the exhaust valve 6 are all closed. Under the action of the pressure difference between the liquid container and the external environment, the high-temperature liquid in the liquid container 1 will quickly flow into the raw material container 9 through the liquid outlet pipe 3 to prepare a beverage.

Fig. 4 shows a state where the pressure in the liquid container 1 in the liquid supply device rises too fast and is in a state of pressure release. In this state, the one-way valve 2 and the exhaust valve 6 are closed, and the safety valve 5 is opened. Arrows in FIGS. 2 to 4 show the flow direction of the liquid in the liquid container 1 when heating and brewing beverages.

Usually, the liquid outlet pipe 3 extends into the liquid container 1 through a higher position of the liquid container 1, at least to ensure that the highest part of the liquid outlet pipe 3 needs to be higher than the highest part of the liquid container 1, so as to ensure that it is not heated by the heating pipe 4 Before the liquid in the liquid container 1 is full, it will not be discharged into the raw material container 9 through the liquid outlet pipe 3.

The one-way valve 2 on the liquid container 1 can effectively prevent the pre-heated or heated liquid in the liquid container 1 from flowing out of the liquid container 1 through the one-way valve 2 in reverse, and can also effectively prevent the pressure in the closed environment from passing through the one-way valve. valve 2 to release the pressure.

The liquid supply device of the embodiment of the present invention can prepare various beverages, such as coffee, tea or fruit juice, by means of containing different powder and/or granular raw materials.
