For example, "upper" and "lower" are not necessarily limited to the directions opposite to or consistent with the direction of gravity.

[0032] As Figures 1 to 5 shown, it is a preferred embodiment of a faucet to which the heat tank exhaust structure of the present utility model is applied. The faucet includes a water box 1, a hot water pipe 2, an exhaust pipe 3, a one-way valve 4 and a cold water pipe 5, and the above-mentioned hot water pipe 2, exhaust pipe 3 and one-way valve 4 form a heat tank exhaust structure.

[0033] The above faucet is installed above the cabinet and is the water outlet component of a water purifier (not shown in the figure). The main body of the water purifier is installed below the cabinet, which has a heat tank and has a hot water outlet, a hot air outlet and a cold water outlet. This is a conventional structure and will not be elaborated here.

[0034] Among them, the water box 1 includes a box body 11, a cover body 12 covering the top of the box body 11 and a hot water connecting pipe 13 arranged inside the box body 11.

[0035] Specifically, the rear side of the box body 11 has a hot water joint 111 and a cold water joint 112 communicating with the inner cavity of the box body 11. The above-mentioned hot water joint 111 and cold water joint 112 are arranged side by side. A hot water inlet 1111 is formed at the port of the hot water joint 111, and a cold water inlet 1121 is formed at the port of the cold water joint 112;

[0036] The bottom of the box body 11 has a water outlet seat 113. The water outlet seat 113 includes an outer cylinder 1131, an inner cylinder 1132 arranged inside the outer cylinder 1131 and a connecting piece 1133 connecting between the outer cylinder 1131 and the inner cylinder 1132. A hot water outlet 1134 is formed inside the inner cylinder 1132, and a cold water outlet 1135 is formed between the outer cylinder 1131, the inner cylinder 1132 and the connecting piece 1133; the inlet end and the outlet end of the above-mentioned hot water connecting pipe 13 are respectively connected to the above-mentioned hot water inlet 1111 and hot water outlet 1134.

[0037] The hot water pipe 2 is used for discharging the hot water generated by the heat tank. Its inlet end is connected to the hot water outlet of the water purifier body, and its outlet end is connected to the above-mentioned hot water joint 111, so as to communicate with the hot water inlet 1111. The middle part of the hot water pipe 2 has a vent 21.

[0038] The exhaust pipe 3 is used for discharging the hot air generated by the heat tank. Its inlet end is connected to the hot air outlet of the water purifier body, and its outlet end is connected to the vent 21 of the hot water pipe 2.

[0039] The one-way valve 4 is installed at the outlet end of the exhaust pipe 3 and only allows the fluid to enter the hot water pipe 2 from the exhaust pipe 3. In this embodiment, the one-way valve 4 includes a valve seat 41 and a valve plate 42.

[0040] Specifically, the valve seat 41 is installed at the air outlet end of the exhaust pipe 3, and its circumference is sealingly fitted with the inner peripheral wall of the exhaust pipe 3; a clamping hole 411 is formed in the middle of the valve seat 41, and a plurality of flow holes 412 are arranged at intervals along the circumference of the clamping hole 411 on the surface of the valve seat 41;

[0041] The valve disc 42 includes an installation part 421 and an elastic part 422; the installation part 421 is a buckle, which is clamped in the clamping hole 411 and is sealingly fitted with the clamping hole 411; the elastic part 422 is in a sheet shape and covers the outside of the flow hole 412;

[0042] In a state without external force, the elastic part 422 is closely attached to the surface of the valve seat 41 facing the hot water pipe 2 under the action of its own elastic force to cover the flow hole 412, so as to close the flow hole 412;

[0043] In a state where the pressure on the exhaust pipe 3 side is greater than the pressure on the hot water pipe 2 side, the elastic part 422 is bent and deformed under the action of the pressure difference to disengage from the flow hole 412, so as to open the flow hole 412.

[0044] For the above-mentioned valve disc 42, the elastic part 422 can be made of an elastic material only, or the whole valve disc 42 can be made of an elastic material. In this embodiment, for the convenience of processing, the valve disc 42 is an integral part with elasticity.

[0045] The cold water pipe 5 is used for discharging the cold water of the water purifier body. Its water inlet end is connected to the cold water outlet of the water purifier body, and its water outlet end is connected to the above-mentioned cold water joint 112, so as to communicate with the cold water inlet 1121.

[0046] The working principle of this embodiment is as follows:

[0047] When the water purifier body works, hot air will be generated when the hot water tank heats the water. At this time, the hot air generated by heating will reach the one-way valve 4 through the exhaust pipe 3. At this time, the hot air will generate a certain pressure to push open the elastic part 422 of the valve disc 42 and open the flow hole 412. At this time, the hot air can enter the ventilation port 21 through the flow hole 412, and then be discharged through the hot water pipe 2 and the hot water connection pipe 13 through the hot water outlet 1134 to achieve internal and external pressure balance;

[0048] When the hot water tank finishes heating and does not generate a large amount of hot air, the elastic part 422 will reset under the action of its own elastic force to close the flow hole 412. At this time, the water intake operation can be carried out;

[0049] In the above solution, although the exhaust and the hot water outlet share a hot water outlet 1134, the one-way valve 4 can be used to ensure that the two do not affect each other; through such an integrated method, the internal space of the faucet can be greatly utilized, and the size of the faucet is basically the same as that of a normal hot water faucet.
