[0027] The technical solution of the present utility model will be further described below in conjunction with the embodiments and drawings.

[0028] Please also refer to Figures 1 to 3The embodiment of the present utility model discloses a water purifier, including a water purifier body and a faucet, which is arranged on the water purifier body. The fully enclosed faucet of this scheme includes a faucet body 1 and a water outlet assembly, and the water outlet assembly includes a water outlet body 3 and a one-way valve 2. The water outlet body 3 is provided with a water outlet channel having a first water inlet 312 and a first water outlet 33. The one-way valve 2 is arranged in the water outlet channel. The one-way valve 2 is used to conduct water from the first water inlet 312 to the first water outlet 33 under the action of water pressure. The faucet body 1 is provided with a second water inlet 111 and a second water outlet 121 that are interconnected. The water outlet body 3 is connected to the faucet body 1, and the first water inlet 312 is connected to the second water outlet 33. The water outlet 121 and the one-way valve 2 are used to open under the action of the water pressure in the faucet body 1. Specifically, when the user turns on the faucet, the pure water in the faucet flows through the second water inlet 111, the second water outlet 121, the first water inlet 312 in sequence and enters the water outlet channel. The one-way valve 2 will automatically open under the action of the water pressure, so that the pure water can flow out from the second water outlet 121. When the user turns off the faucet, the one-way valve 2 is no longer affected by the water pressure in the faucet, and the one-way valve 2 automatically closes, thereby preventing bacteria from entering the faucet from the second water outlet 121. With such a design, by adding a one-way valve 2 at the water outlet position of the faucet, it can be ensured that only pure water can flow out of the faucet, preventing bacteria from entering the faucet, thereby maintaining the hygiene of the pure water inside the faucet.

[0029] Furthermore, the fully enclosed faucet further includes a filter 4, which is arranged in the water outlet body 3 and between the one-way valve 2 and the first water outlet 33. With such a design, the filter 4 can filter the pure water to be discharged, thereby further improving the water quality of the discharged pure water.

[0030] In some embodiments, to facilitate installation of the one-way valve 2 and the filter 4 on the spout body 3, a first cavity 31 and a second cavity 32 are sequentially provided within the spout body 3, extending from the faucet body 1 toward the faucet body 1. The one-way valve 2 and the filter 4 are both located within the first cavity 31, while the second cavity 32 forms a first water outlet 33. With this design, water at the second water outlet 121 first enters the first cavity 31, passes through the one-way valve 2 and the filter 4, and then enters the second cavity 32 before being discharged.

[0031] Furthermore, to ensure proper installation and positioning of the one-way valve 2 and the filter screen 4 on the water outlet body 3, the inner diameter of the first cavity 31 is larger than the inner diameter of the second cavity 32, and the outer diameters of the one-way valve 2 and the filter screen 4 are both larger than the inner diameter of the second cavity 32. This design prevents the one-way valve 2 and the filter screen 4 from falling off the first water outlet 33, as both the outer diameters of the one-way valve 2 and the filter screen 4 are larger than the inner diameter of the second cavity 32.

[0032] Furthermore, the outer edge of the filter screen 4 abuts between the stepped surface of the first cavity 31 and the one-way valve 2, and the middle area of the filter screen 4 bulges outward toward the second cavity 32. With this design, a space for pure water to flow can be formed between the one-way valve 2 and the filter screen 4.

[0033] In some embodiments, to achieve a detachable connection between the spout body 3 and the faucet body 1, a first thread 122 is provided on the faucet body 1, and a second thread 311 is provided on the spout body 3. The spout body 3 is detachably connected to the faucet body 1 through the cooperation of the second thread 311 and the first thread 122. The threaded connection method, on the one hand, has a simple structure and high sealing performance; on the other hand, by disposing the one-way valve 2 in the spout body 3 and detachably connecting the spout body 3 to the faucet body 1, the spout assembly can be detachably connected to the faucet body 1. When dirt accumulates on the one-way valve 2 and the spout body 3, the spout assembly can be disassembled to clean the spout body 3 and the one-way valve 2, thereby further ensuring the cleanliness and hygiene of the faucet.

[0034] It is understandable that in other optional implementations, the water spout body 3 and the faucet body 1 may be integrally formed, which is not limited here.

[0035] Specifically, the first thread 122 is an external thread provided at the second water outlet 121 of the faucet body 1, and the second thread 311 is an internal thread provided in the first cavity 31 of the spout body 3. It is understood that in other embodiments, the first thread 122 may be an internal thread and the second thread 311 may be an external thread, and this is not limited here.

[0036] In some embodiments, the faucet body 1 includes a faucet housing 11 and a rotating arm 12. The rotating arm 12 and the faucet housing 11 are rotatably connected. The second water inlet 111 is provided on the faucet housing 11, the second water outlet 121 is provided on the rotating arm 12, and the spout body 3 is connected to the rotating arm 12. With this design, the position of the second water outlet 121 can be adjusted by rotating the rotating arm 12, thereby conveniently meeting the different usage needs of users.

[0037] Furthermore, in order to fix the fully enclosed faucet on the water purifier body, the fully enclosed faucet also includes a threaded tube 5, the faucet housing 11 is fixed to the threaded tube 5, and the threaded tube 5 is used to connect with the water purifier body to fix the fully enclosed faucet on the water purifier body.

[0038] The utility model provides a water purifier, which includes a faucet body 1 and a water outlet assembly, the water outlet assembly includes a water outlet body 3 and a one-way valve 2, the water outlet body 3 is provided with a water outlet channel having a first water inlet 312 and a first water outlet 33, the one-way valve 2 is provided in the water outlet channel, the one-way valve 2 is used to conduct along the direction from the first water inlet 312 to the first water outlet 33 under the action of water pressure, the faucet body 1 is provided with a second water inlet 111 and a second water outlet 121 that are interconnected, the water outlet body 3 is connected to the faucet body 1 and the first water inlet 312 Connected to the second water outlet 121, the one-way valve 2 is used to open under the action of the water pressure in the faucet body 1. Specifically, when the user turns on the faucet, the pure water in the faucet flows through the second water inlet 111, the second water outlet 121, the first water inlet 312 in sequence and enters the water outlet channel. The one-way valve 2 will automatically open under the action of the water pressure, so that the pure water can flow out from the second water outlet 121. When the user turns off the faucet, the one-way valve 2 is no longer affected by the water pressure in the faucet, and the one-way valve 2 automatically closes, thereby preventing bacteria from entering the faucet from the second water outlet 121. With this design, by adding a one-way valve 2 at the water outlet position of the faucet, it can be ensured that only pure water can flow out of the faucet, preventing bacteria from entering the faucet, thereby maintaining the hygiene of the pure water inside the faucet.

[0039] The above is a detailed introduction to a fully enclosed faucet and a water purifier disclosed in the embodiment of the present invention. This article uses individual examples to illustrate the principle and implementation method of the present invention. The description of the above embodiment is only used to help understand the fully enclosed faucet and the water purifier and its core idea of the present invention; at the same time, for general technical personnel in this field, according to the idea of the present invention, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
