Detailed Implementation

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] This utility model relates to a water tank, including a water tank body 100, a water inlet mechanism, and a foam generating mechanism 300.

[0030] like Figure 1 , Figure 2 and Figure 3As shown, a bubble outlet 110 is provided on the side wall of the sink body 100. The shape of the bubble outlet 110 is not limited; it can be a strip-shaped opening, a round hole, etc. The bubble outlet 110 can be flush with the inner wall of the sink body 100, or it can extend partially into the inner cavity of the sink body 100. The water inlet mechanism includes a water inlet pipe 210 and a control valve 220. The control valve 220 can be a mechanical manual valve or a sensor-operated electronic valve, etc. The control valve 220 can be installed on the edge 120 of the sink body 100. The control valve 220 is connected to the water inlet pipe 210, one end of which can be connected to a tap water pipe, and the other end can be connected to the foam generating mechanism 300. The foam generating mechanism 300 can be placed below the sink body 100, without occupying the space above the sink body 100. The control valve 220 controls the opening and closing of the water inlet pipe 210, thereby controlling whether water is supplied to the foam generating mechanism 300. The foam generating mechanism 300 can be connected to the foam outlet 110 via a hose or similar means. In use, the user opens the control valve 220, allowing tap water to flow into the foam generating mechanism 300 through the inlet pipe 210. This water mixes with the foaming liquid in the mechanism, forming foam that is then transported to the foam outlet 110 and discharged from there into the inner cavity of the sink body 100 for the user's use. When the control valve 220 is closed, water supply to the foam generating mechanism 300 stops, and foam generation ceases. The location of the foam outlet 110 allows the foam to be discharged directly into the inner cavity of the sink body 100 for use, preventing splashing onto the outside of the sink body 100. Furthermore, the location of the foam outlet 110 does not occupy the space above the sink body 100 and will not interfere with other objects above or around the sink body 100. The foam generating mechanism 300 generates foam for users to use directly, eliminating the need for users to manually mix the foaming liquid with water, making it very convenient to use.

[0031] In one embodiment, such as Figure 1 , Figure 2 and Figure 3As shown, the foam generating mechanism 300 includes a liquid supply section 310, a functional section 320, and a mixing section 330. The liquid supply section 310, functional section 320, and mixing section 330 all have internal cavities. The liquid supply section 310 is a storage container for storing the foaming liquid. The interior of the functional section 320 is divided into a water passage chamber 321 and a solvent chamber 322 by a piston member 400. The liquid supply section 310, mixing section 330, and water inlet pipe 210 are all connected to the functional section 320. Specifically, the liquid supply section 310 and the solvent chamber 322 can be connected by a pipe, allowing the liquid supply section 310 to unidirectionally supply foaming liquid to the solvent chamber 322. A check valve can be installed at the outlet of the liquid supply section 310 to ensure that the foaming liquid in the liquid supply section 310 can only flow unidirectionally towards the solvent chamber 322. The water inlet pipe 210 is connected to the water passage chamber 321, allowing the water inlet pipe 210 to supply water to the water passage chamber 321. The water passage chamber 321 can be connected to the mixing section 330 via a pipe. Water from the water passage chamber 321 is unidirectionally supplied to the mixing section 330. A check valve can be installed at the interface between the water passage chamber 321 and the mixing section 330 to ensure that the water in the water passage chamber 321 can only flow unidirectionally towards the mixing section 330. The solvent chamber 322 and the mixing section 330 can be connected via a pipe. The foaming liquid in the solvent chamber 322 can be unidirectionally supplied to the mixing section 330. A check valve can be installed at the connection between the solvent chamber 322 and the mixing section 330 to ensure that the foaming liquid in the solvent chamber 322 can only flow unidirectionally towards the mixing section 330. The mixing section 330 can be connected to the foam outlet 110 via a hose. The piston 400 moves within the functional section 320 according to changes in the water pressure in the water passage chamber 321. During this movement, the volumes of the water passage chamber 321 and the solvent chamber 322 change accordingly. Figure 4As shown, during use, control valve 220 is opened, and water is supplied to the water passage chamber 321 through the water inlet pipe 210. The water pressure in the water passage chamber 321 increases, causing the piston 400 to move in the direction of decreasing volume in the solvent chamber 322. The volume of the water passage chamber 321 gradually increases, while the volume of the solvent chamber 322 gradually decreases. At this time, the foaming liquid in the solvent chamber 322 is squeezed out and flows into the mixing section 330. Simultaneously, the water in the water passage chamber 321 also gradually flows into the mixing section 330. The water and foaming liquid in the mixing section 330 mix to form foam, which is discharged from the foam outlet 110 for user use. After closing control valve 220, water supply to the water passage chamber 321 stops, the water pressure in the water passage chamber 321 decreases, and the piston 400 returns to its original position in the direction of increasing volume in the solvent chamber 322. The volume of the solvent chamber 322 gradually increases, while the volume of the water passage chamber 321 gradually decreases. At this time, the expansion of the solvent chamber 322 creates a negative pressure, drawing the foaming liquid from the supply section 310 towards the solvent chamber 322, thus replenishing the foaming liquid in the solvent chamber 322. The speed of water flow to the water passage chamber 321 can be controlled by the control valve 220. Utilizing the Bernoulli effect, the pressure exerted by the water in the water passage chamber 321 on the piston 400 is controlled, and the foaming liquid is drawn into or pushed out of the solvent chamber 322 by the pressure change. By simply operating the control valve 220, the foam generating mechanism 300 can automatically mix and form foam and replenish the foaming liquid in the solvent chamber 322. The user only needs to periodically replenish the supply section 310 with new foaming liquid. Specifically, an elastic element 410 can be provided between the piston 400 and the functional section 320. The elastic element 410 can be a spring, etc. The elastic element 410 applies an elastic force to the piston element 400, causing the piston element 400 to move in the direction that increases the size of the solvent cavity 322. When the water pressure in the water cavity 321 increases, the piston element 400 moves in the direction that decreases the size of the solvent cavity 322, and the elastic element 410 elastically contracts. When the water pressure in the water cavity 321 decreases, the elastic element 410 elastically returns to its original position, pushing the piston element 400 back to its original position in the direction that increases the size of the solvent cavity 322.

[0032] In one embodiment, such as Figure 2 , Figure 3 and Figure 4As shown, the functional unit 320 includes a first housing 500 and a cover 600. The interior of the first housing 500 is divided into a first cavity 510, a second cavity 520, and a third cavity 530. A first liquid passage 540 is provided between the first cavity 510 and the third cavity 530, and a second liquid passage 550 is provided between the second cavity 520 and the third cavity 530. A piston member 400 is slidably mounted in the third cavity 530. The first cavity 510, the second cavity 520, the third cavity 530, and the piston member 400 together form a solvent cavity 322. In this embodiment, the first liquid passage 540 and the second liquid passage 550 are located on the same side wall of the third cavity 530 and are positioned opposite the piston member 400. When the piston member 400 moves toward the side where the first liquid passage 540 and the second liquid passage 550 are located, the space formed by the piston member 400 and the third cavity 530 shrinks, thereby reducing the size of the solvent cavity 322. A cover 600 is fitted onto the first housing 500. The cover 600 has a first connector 610 and a second connector 620. The first connector 610 and the second connector 620 can be integrally formed on the cover 600. One end of the first connector 610 is inserted into the first cavity 510, and the liquid supply section 310 is connected to the first connector 610; alternatively, the other end of the first connector 610 can be inserted into the liquid supply section 310. One end of the second connector 620 is inserted into the second cavity 520, and the mixing section 330 is connected to the second connector 620; alternatively, the other end of the second connector 620 can be inserted into the mixing section 330. The foaming liquid in the liquid supply section 310 is delivered to the first cavity 510 through the first connector 610, and then flows into the third cavity 530 through the first liquid passage 540. The foaming liquid in the third cavity 530 flows into the second cavity 520 through the second liquid passage 550, and then is delivered to the mixing section 330 through the second connector 620.

[0033] Based on the above embodiments, a first one-way valve 710 is provided between the first connector 610 and the first liquid passage 540. The first one-way valve 710 controls the first connector 610 to unidirectionally deliver foaming liquid towards the first chamber 510. A second one-way valve 720 is provided between the second liquid passage 550 and the second connector 620. The second one-way valve 720 controls the solvent chamber 322 to unidirectionally deliver foaming liquid towards the second chamber 520 through the second liquid passage 550.

[0034] A third connector 311 may be provided at the bottom of the liquid supply section 310. The third connector 311 is vertically connected to the first connector 610. The liquid supply section 310 overlaps the functional section 320 and / or the mixing section 330. The functional section 320 and / or the mixing section 330 support the liquid supply section 310. The foaming liquid in the liquid supply section 310 is transported to the solvent chamber 322 by its own weight and the negative pressure of the solvent chamber 322.

[0035] Furthermore, the functional unit 320 also includes a second housing 800 and a fourth connector 810. The second housing 800 is fitted onto the outside of the first housing 500. The interior of the second housing 800 is divided into a fourth cavity 820 and a fifth cavity 830. The fourth cavity 820 and the fifth cavity 830 are connected by a third liquid passage hole 840. The third cavity 830, the fourth cavity 820, the fifth cavity 830, and the piston member 400 define a water passage cavity 321. When the piston member 400 moves in the direction where the solvent cavity 322 becomes smaller, a portion of the third cavity 530 communicates with the fourth cavity 820 to form part of the water passage cavity 321. One end of the fourth connector 810 is inserted into the fifth cavity 830, and the other end of the fourth connector 810 can be connected to the mixing unit 330 via a hose. A third one-way valve 730 is provided between the third liquid passage 840 and the fourth connector 810. The third one-way valve 730 controls the water to flow from the third liquid passage 840 into the fifth chamber 830 and then flow unidirectionally toward the mixing section 330.

[0036] Based on the above embodiments, such as Figure 3 As shown, one end of the piston 400 extends into the water passage cavity 321. When the piston 400 moves in the direction where the volume of the solvent cavity 322 increases, the end of the piston 400 can move to abut against the inner wall of the second housing 800, thereby limiting the stroke of the piston 400 in the direction where the solvent volume of the solvent cavity 322 increases. Figure 4 As shown, when the piston 400 moves in the direction where the volume of the solvent chamber 322 decreases, the end of the piston 400 leaves the inner wall of the second housing 800, one end of the elastic member 410 can abut against the piston 400, and the other end abuts against the cavity wall of the third cavity 530.
