Description

Technical Field

[0001] This utility model belongs to the field of faucet structure technology, and relates to a faucet, particularly a water filter faucet. Background Technology

[0002] In order to ensure water safety, many families connect external filter devices to the faucet inlet through corrugated connecting pipes or directly choose faucet outlets with built-in filters.

[0003] Both of these filtration structures have drawbacks. External filtration equipment requires the installation of a relatively large filter, and the cost of regular replacement is relatively high. The filter screen outlet is usually difficult to disassemble, and after long-term use, scale and impurities adhere to the filter screen, resulting in poor filtration performance. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a water filter faucet that combines the advantages of easy disassembly and replacement of the filter screen with reduced replacement costs.

[0005] The purpose of this utility model can be achieved through the following technical solution: A water filter faucet, including a faucet base and a faucet bend, characterized in that a filter assembly is provided between the faucet base and the faucet bend, the filter assembly including a shell and a water-passing plate integrally formed inside the shell, a water-passing cylinder integrally formed at the bottom of the water-passing plate, an external thread at the lower end of the water-passing cylinder, multiple pre-filter water-passing holes on the water-passing cylinder between the external thread and the water-passing plate, multiple post-filter water-passing holes on the water-passing plate, a sealing sleeve threadedly connected to the water-passing cylinder inside the shell, a sealing ring installed on the sealing sleeve to seal between the sealing sleeve and the shell, a water purification filter material provided between the sealing sleeve and the water-passing plate, and the water purification filter material is sleeved on the filter cylinder and fills the space between the filter cylinder and the shell, and the bottom of the water-passing cylinder has a water inlet opening.

[0006] In the aforementioned water filter faucet, the top and bottom outer edges of the outer shell are provided with connecting flanges, and the faucet bend and the faucet base are provided with flange portions that connect to the corresponding connecting flanges.

[0007] In the aforementioned water filter faucet, the top of the sealing sleeve has a positioning step, and the bottom of the water purification filter material has a corresponding step groove.

[0008] In the aforementioned water filter faucet, a sealing gasket is provided between the connecting flange and the flange portion.

[0009] In one of the aforementioned water filter faucets, the bottom end of the faucet's curved pipe extends into the outer casing.

[0010] In the aforementioned water filter faucet, a second sealing ring is provided at the top of the sealing sleeve and between it and the filter cylinder.

[0011] Compared with existing technologies, this water filter faucet has the following advantages: 1. The filter structure is easy to replace, improving performance and lifespan; 2. Reduce the cost of using the filtration function; only the filter media needs to be replaced. Attached Figure Description

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figure 1-3 As shown, this water filter faucet includes a faucet base 1 and a faucet bend 2. A filter assembly is provided between the faucet base 1 and the faucet bend 2. The filter assembly includes a housing 3 and a water-passing plate 4 integrally formed inside the housing 3. A water-passing cylinder 5 is integrally formed at the bottom of the water-passing plate 4. An external thread is provided at the lower end of the water-passing cylinder 5. Multiple pre-filter water-passing holes 6 are provided on the water-passing cylinder 5 between the external thread and the water-passing plate 4. Multiple post-filter water-passing holes 7 are provided on the water-passing plate 4. A sealing sleeve 8 is provided inside the housing 3 and threadedly connected to the water-passing cylinder 5. A sealing ring 9 is installed on the sealing sleeve 8 to seal between the housing 3 and the sealing sleeve 8. A water purification filter material 10 is provided between the sealing sleeve 8 and the water-passing plate 4. The water purification filter material 10 is sleeved on the filter cylinder and fills the space between the filter cylinder and the housing 3. The bottom of the water-passing cylinder 5 has a water inlet opening 11.

[0018] To elaborate further, the outer edges of the top and bottom of the outer casing 3 are equipped with connecting flanges 12. The faucet bend 2 and the faucet base 1 are equipped with flange portions 13 that connect to the corresponding connecting flanges 12. When the water purification filter material 10 needs to be replaced, the screws of the connecting flanges 12 and flange portions 13 are unscrewed, and the faucet bend 2, the outer casing 3, and the sealing sleeve 8 inside the outer casing 3 are removed in sequence. The water purification filter material 10 is then replaced, and the components are reassembled in sequence.

[0019] To elaborate further, the top of the sealing sleeve 8 has a positioning step 14, and the bottom of the water purification filter material 10 has a corresponding step groove 15, achieving a higher positioning and installation effect for the water purification filter material 10.

[0020] Preferably, a sealing gasket 16 is provided between the connecting flange 12 and the flange portion 13.

[0021] Preferably, the bottom end of the faucet bend 2 extends into the outer casing 3.

[0022] Preferably, a sealing ring 17 is provided at the top of the sealing sleeve 8 and between it and the filter cylinder.
