Description

Technical Field

[0001] This utility model relates to water-using equipment, and more particularly to water-using equipment with a water tank. Background Technology

[0002] Water-using equipment typically uses water tanks to store purified water or mineral water. A valve is located at the bottom of the tank; it opens when the tank is placed on a base and automatically closes when the tank is removed to prevent leakage. Because a vacuum zone, creating a negative pressure chamber, exists within the tank after water is drawn from it, this chamber makes water extraction difficult. Therefore, an air inlet is needed to release pressure from this chamber. However, this air inlet must also prevent water from flowing out. A common practice is to install a separate one-way valve at the air inlet to prevent liquid from flowing out of the tank. This method requires more parts and has a more complex structure. Utility Model Content

[0003] The main technical problem to be solved by this utility model is to provide a water tank assembly that enables the synchronous opening and closing of the air inlet channel and the water outlet channel, and the structure is relatively simple.

[0004] To solve the above-mentioned technical problems, this utility model provides a water tank assembly, including a water tank and a base; a valve is provided at the bottom of the water tank, and a top abutment that cooperates with the valve is provided on the side of the base facing the water tank; the base is also provided with an air inlet and a water outlet.

[0005] The water tank and valve define an air inlet channel and a water outlet channel. When the valve is disengaged from the abutment, the valve closes the air inlet channel and the water outlet channel. When the valve is engaged with the abutment, the valve opens the air inlet channel and the water outlet channel, so that the air inlet is connected to the inner cavity of the water tank through the air inlet channel, and the inner cavity of the water tank is connected to the water outlet through the water outlet channel.

[0006] In a preferred embodiment: the water tank includes a water tank body and a water tank cover, the water tank cover is disposed at the bottom of the water tank body and is joined with the water tank body through a sealing gasket to form the inner cavity of the water tank.

[0007] In a preferred embodiment: the water tank cover is provided with a chamber for installing the valve, and the two ends of the chamber are open faces; the valve is provided with an air inlet channel, and the water outlet channel is formed between the side wall of the valve and the inner wall of the chamber.

[0008] In a preferred embodiment: the valve is provided with a sealing surface, and when the valve and the top abutment are disengaged, the sealing surface fits against the inner wall of the chamber to close the air inlet channel and the water outlet channel.

[0009] In a preferred embodiment: the sealing surface is located higher than the air outlet of the air inlet channel and the water inlet of the water outlet channel.

[0010] In a preferred embodiment, the opening of the chamber facing the inner cavity has a structure in which the inner diameter gradually decreases along the direction of water flow.

[0011] In a preferred embodiment: the upper end of the valve opens radially outward to form a plug, and when the valve and the abutment are released from their abutment engagement, the plug fits and seals against the opening surface of the chamber facing the inner cavity.

[0012] In a preferred embodiment: the top abutment is provided with a first through channel along its thickness for connecting the air intake channel and the air intake hole.

[0013] In a preferred embodiment: the base is further provided with a second through channel spaced apart from the first through channel, for connecting the water outlet channel and the water outlet hole;

[0014] In a preferred embodiment: when the valve and the abutment are engaged, the resulting abutment force causes the valve to deform in order to open the air inlet channel and the water outlet channel.

[0015] This invention also provides a sprayer that uses the water tank assembly described above.

[0016] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0017] This invention provides a water tank assembly that uses a single valve to simultaneously seal and open the air inlet and water outlet channels. This allows the air inlet and water outlet channels to remain normally closed when the water tank is not installed on the base, preventing water from flowing out of the air inlet channel. Existing technologies typically require two separate parts to seal the air inlet and water outlet channels, such as a one-way valve on the air inlet channel. This invention uses a single part to close both channels, simplifying the structure. Attached Figure Description

[0027] To make the technical solution and features of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific examples. It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.

[0028] refer to Figures 1-7 A water tank assembly includes a water tank 1 and a base 2; a valve 11 is provided at the bottom of the water tank 1, and a top abutment 21 that cooperates with the valve 11 is provided on the side of the base 2 facing the water tank 1; the base 2 is also provided with an air inlet 22 and a water outlet 23.

[0029] The water tank 1 and valve 11 define an air inlet channel 12 and a water outlet channel 13. When the valve 11 is disengaged from the abutment member 21, the valve 11 closes the air inlet channel 12 and the water outlet channel 13. When the valve 11 is engaged with the abutment member 21, the valve 11 opens the air inlet channel 12 and the water outlet channel 13, so that the air inlet 22 is connected to the inner cavity of the water tank 1 through the air inlet channel 12, and the inner cavity of the water tank 1 is connected to the water outlet 23 through the water outlet channel 13. In this way, when both the air inlet channel 12 and the water outlet channel 13 are open, the terminal device can draw water out of the inner cavity of the water tank 1 through the water outlet channel 13. After the water in the water tank 1 is drawn out, a negative pressure chamber is formed. Outside air enters the negative pressure chamber through the air inlet 22 and the air inlet channel 12 to release pressure. In this way, the water in the water tank 1 can be continuously drawn out by the terminal device, and outside air can also be continuously replenished into the water tank 1.

[0030] The aforementioned water tank 1 assembly achieves simultaneous sealing and opening of the air inlet channel 12 and the water outlet channel 13 through a valve 11. This allows the air inlet channel 12 and the water outlet channel 13 to remain normally closed when the water tank 1 is not installed on the base 2. Compared with the prior art, which uses two parts to close the air inlet channel 12 and the water outlet channel 13 respectively, the structure is simplified.

[0031] In this embodiment, the water tank 1 includes a water tank body 14 and a water tank cover 15. The water tank cover 15 is disposed at the bottom of the water tank body 14 and is joined with the water tank body 14 through a sealing gasket 16 to form the inner cavity of the water tank 1. The sealing gasket 16 prevents water in the inner cavity from leaking out from the joint between the water tank body 14 and the water tank cover 15.

[0032] To define the air inlet channel 12 and water outlet channel 13 with valve 11, the water tank cover 15 is provided with a chamber for installing valve 11, with open faces at both ends of the chamber; the air inlet channel 12 is provided inside valve 11, and the water outlet channel 13 is formed between the side wall of valve 11 and the inner wall of the chamber. Thus, when valve 11 is installed in the chamber, valve 11 and water tank cover 15 together form the air inlet channel 12 and water outlet channel 13.

[0033] Specifically, the opening 151 of the chamber facing the inner cavity has a structure with a gradually decreasing inner diameter along the direction of water flow. The upper end of the valve 11 opens radially outward to form a plug 111. When the valve 11 and the abutment 21 are disengaged, the side wall of the plug 111 forms a sealing surface that fits and seals against the opening 151 of the chamber facing the inner cavity. Since the air outlet of the air inlet channel 12 and the water inlet of the water outlet channel 13 are both lower than the opening 151 of the chamber facing the inner cavity, the sealing surface is also higher than the air outlet of the air inlet channel 12 and the water inlet of the water outlet channel 13. Therefore, when the sealing surface fits and seals against the opening 151, both the air inlet channel 12 and the water outlet channel 13 are closed.

[0034] In this embodiment, valve 11 is made of a flexible material, preferably silicone. When valve 11 is engaged with the abutment member 21, valve 11 deforms upward due to the action of the abutment member 21, causing the plug 111 to move upward. This causes the side wall of plug 111 to separate from the opening surface 151 of the chamber facing the inner cavity, thus releasing the seal and opening the opening surface 151 of the chamber facing the inner cavity. Since the air outlet of air inlet channel 12 and the water inlet of water outlet channel 13 are both lower than the opening surface 151 of the chamber facing the inner cavity, opening the opening surface 151 of the chamber facing the inner cavity opens both air inlet channel 12 and water outlet channel 13.

[0035] To connect the air intake channel 12 and the air intake hole 22, the top abutment 21 is provided with a first through channel 211 along its thickness to connect the air intake channel 12 and the air intake hole 22. Similarly, to connect the water outlet channel 13 and the water outlet hole 23, the base 2 is also provided with a second through channel 24 spaced apart from the first through channel to connect the water outlet channel 13 and the water outlet hole 23. Since the first through channel 211 and the second through channel 24 are spaced a certain distance apart, the independence of the water and air paths can be ensured, and water leakage will not occur.

[0036] The aforementioned water tank assembly 1 can be applied to various water-using devices, such as coffee machines, water dispensers, sprayers, etc. This embodiment uses a sprayer as an example. Figure 8-9 In addition to the water tank assembly 3, the sprayer also includes an air pump 4, a hose 5, and a nozzle 6. The nozzle 6 is provided with a liquid spray port 61 and an air spray port 62, which are connected to the water outlet 23 of the water tank assembly 3 and the air outlet of the air pump 4, respectively, through the hose 5.

[0037] It should be noted that the water tank in this embodiment is not limited to water in the conventional sense. Any liquid that can flow can be loaded into the water tank, such as skin care water, toner, beauty serum, etc.

[0038] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
