Description

Technical Field

[0001] The utility model relates to the technical field of kitchen faucets, in particular to a water purification faucet with a filter element that can be repeatedly cleaned and used. Background Technique

[0002] A faucet is a common name for a water valve, which is used to control the size of the water flow and has the function of saving water. In order to purify tap water to remove impurities therein and ensure the safety of water use, existing faucets usually use a filter element to filter impurities in tap water. The filtered impurities accumulate on the outside of the filter element. In order to ensure the purification efficiency of the filter element, the filter element needs to be replaced regularly. However, replacing the filter element increases the use cost of the device. For this reason, a water purification faucet with a filter element that can be repeatedly cleaned and used is proposed. However, most of the filter elements in existing water purification faucets that can be repeatedly cleaned and used are cleaned on the outside of the filter element with a steel wool ball or a rag, which is easy to damage the filter element and reduce the service life of the filter element. Content of the Utility Model

[0003] Aiming at the above problems, the purpose of the utility model is to provide a water purification faucet with a filter element that can be repeatedly cleaned and used, and solve the problem that most of the filter elements in existing water purification faucets that can be repeatedly cleaned and used are cleaned on the outside of the filter element with a steel wool ball or a rag, which is easy to damage the filter element and reduce the service life of the filter element.

[0004] In order to achieve the above purpose, the technical scheme adopted by the utility model is: a water purification faucet with a filter element that can be repeatedly cleaned and used, including a faucet body and a filter element mounting seat. A valve is installed at the bottom of the faucet body, and a first sealing gasket is connected above the valve. The top of the faucet body is bolted with a water purification chamber, and a second sealing gasket is installed on the top of the water purification chamber. An arc-shaped brush plate is welded and installed inside the water purification chamber, and a scraping ring is installed inside the upper half of the water purification chamber. A circular scraping piece is welded below the scraping ring, and a brush ring is installed inside the scraping ring. The filter element mounting seat is installed inside the water purification chamber, and a first filter element is installed on the outside of the filter element mounting seat. A second filter element is arranged inside the first filter element. An outlet pipe is threadedly connected above the filter element mounting seat, and a sealing ring is installed at the connection between the outlet pipe and the filter element mounting seat.

[0005] The beneficial effect of the utility model is: rotate the filter element mounting seat to remove the filter element mounting seat from the water purification chamber. During the process of screwing out the filter element mounting seat, the arc-shaped brush plate cleans the bottom of the first filter element. During the process of pulling out the first filter element, the circular scraping piece and the brush ring installed on the scraping ring can clean the outside of the first filter element. The above process can comprehensively and reliably clean the outside of the first filter element, and the damage to the first filter element during cleaning is relatively small.

[0006] In order to facilitate the installation of the first sealing gasket:

[0007] As a further improvement of the above technical solution: a snap-fit installation structure is adopted between the first sealing gasket and the water purification chamber.

[0008] The beneficial effect of this improvement is that the snap-fit installation structure can make the connection between the first sealing gasket and the water purification chamber more reliable and firm.

[0009] For the convenience of installing the filter element mounting seat:

[0015] As a further improvement of the above technical solution: the first filter element and the water purification chamber are arranged with their axes coincident.

[0016] The beneficial effect of this improvement is that the arrangement with coincident axes can enable the first filter element to be comprehensively and reliably cleaned in cooperation with the scraping ring and the annular scraping blade when the first filter element is drawn out from the inside of the water purification chamber.

[0017] As a further improvement of the above technical solution: the arc-shaped brush plate is closely attached to the bottom of the first filter element.

[0018] The beneficial effect of this improvement is that the close attachment can make the cleaning of the first filter element by the arc-shaped brush plate more comprehensive and reliable.

[0019] To ensure the tightness at the connection between the faucet body and the water purification chamber:

[0020] As a further improvement of the above technical solution: a plug-in connection is adopted between the faucet body and the water purification chamber.

[0021] The beneficial effect of this improvement is that the faucet body and the water purification chamber are sealed at their connection by the first sealing gasket, and the plug-in connection can ensure the tightness at the connection between the faucet body and the water purification chamber.

[0022] To ensure the tightness at the connection between the filter element mounting seat and the water outlet pipe:

[0023] As a further improvement of the above technical solution: the number of the sealing rings is two.

[0024] The beneficial effect of this improvement is that two sealing rings can effectively ensure the tightness of the connection between the filter element mounting seat and the water outlet pipe. Description of the Drawings

A second filter element 32 is arranged inside the first filter element 31. An outlet pipe 4 is threadedly connected above the filter element mounting seat 3, and a sealing ring 41 is installed at the connection between the outlet pipe 4 and the filter element mounting seat 3. Rotate the filter element mounting seat 3 to remove the filter element mounting seat 3 from the water purification tank 2. During the process of screwing out the filter element mounting seat 3, the arc-shaped brush plate 22 cleans the bottom of the first filter element 31. During the process of pulling out the first filter element 31, the circular scraping piece 24 and the brush ring 25 installed on the scraping ring 23 can clean the outside of the first filter element 31. The above process can comprehensively and reliably clean the outside of the first filter element 31, and the damage to the first filter element 31 during cleaning is relatively small. The first sealing gasket 12 and the water purification tank 2 are in a snap-fit installation structure. The snap-fit installation structure can make the connection between the first sealing gasket 12 and the water purification tank 2 more reliable and firm. The filter element mounting seat 3 and the water purification tank 2 are in a threaded connection. The threaded connection can make the connection between the filter element mounting seat 3 and the water purification tank 2 more reliable and can also ensure the tightness at the connection between the filter element mounting seat 3 and the water purification tank 2. The bottom of the scraping ring 23 is inclined, and the scraping ring 23 and the water purification tank 2 are arranged with their axes coinciding. The inclined scraping ring 23 can cooperate with the circular scraping piece 24 to comprehensively clean the outside of the first filter element 31. The first filter element 31 and the water purification tank 2 are arranged with their axes coinciding. The axis-coinciding arrangement can enable the first filter element 31 to cooperate with the scraping ring 23 and the circular scraping piece 24 to comprehensively and reliably clean the first filter element 31 when being pulled out from the inside of the water purification tank 2. The arc-shaped brush plate 22 is in close contact with the bottom of the first filter element 31.

The two sealing rings 41 can effectively ensure the tightness at the connection between the filter element mounting seat 3 and the outlet pipe 4.

[0033] The working principle of the present utility model is as follows: When using this device, water enters the interior of the water purification chamber 2 through the faucet body 1. At this time, the first filter element 31 cooperates with the second filter element 32 and the filter element mounting seat 3 to purify tap water. The purified water flows out through the water outlet pipe 4. When it is necessary to clean the first filter element 31 and the second filter element 32, the water purification chamber 2 is unscrewed from the faucet body 1. At this time, the water outlet pipe 4 is removed from the filter element mounting seat 3. Then, the filter element mounting seat 3 is rotated to remove it from the water purification chamber 2. During the process of unscrewing the filter element mounting seat 3, the arc-shaped brush plate 22 cleans the bottom of the first filter element 31. During the process of pulling out the first filter element 31, the annular scraping piece 24 installed on the scraping ring 23 and the brush ring 25 can clean the outer side of the first filter element 31. By this way, the first filter element 31 can be quickly cleaned during the removal process. After the cleaning is completed, water is injected into the filter element mounting seat 3 from the top of the filter element mounting seat 3 for backwashing. Repeating the installation process of the filter element mounting seat 3 can comprehensively and reliably clean the outer side of the first filter element 31, and the damage to the first filter element 31 during cleaning is relatively small. After the cleaning is completed, the interior of the water purification chamber 2 is rinsed, and then the device is reset to realize the reuse of the filter element.
