Description

Technical Field

[0001] This utility model belongs to the field of faucet technology, and specifically relates to a kitchen faucet with a quick-release filter structure. Background Technology

[0002] A faucet is a common name for a water valve. Its main function is to control the water flow and the amount of water coming out of the pipe. It has the effect of saving water and is widely used in various occasions. Traditional tap water contains a lot of impurities, and simple filter screens are not enough to effectively filter these impurities. In order to improve the filtration effect of impurities, existing technologies usually install filter cartridges inside the faucet.

[0003] Chinese patent CN222277597U discloses a faucet for easy filter replacement. The installation assembly includes a fixing ring fixedly installed inside the water outlet pipe, a housing, a sealing sleeve fitted on the housing, a locking sleeve, and an installation sleeve. The filter element is located inside the housing. A locking ring is fixedly installed below the locking sleeve. Threads are provided on both the inner side of the housing and the outer side of the locking sleeve. After the locking sleeve is screwed into the housing, the locking ring is fixedly connected to the filter element. After the housing is inserted into the water outlet pipe, the sealing sleeve abuts against the water outlet pipe and the fixing ring. An installation ring is fixedly installed below the installation sleeve. Threads are provided on both the outer side of the water outlet pipe and the inner side of the installation sleeve. When the installation sleeve is screwed into the water outlet pipe, the installation ring is fixedly connected to the locking ring. Several anti-slip strips are fixedly installed on the outer side of the installation sleeve.

[0004] The above technical solution has the following drawbacks: When disassembling and replacing the filter element of this faucet, the installation sleeve must first be unscrewed to separate the water outlet pipe from the water outlet pipe. Then, the hook plate is inserted into the hook groove and hooks the locking ring. Pulling the hook plate downwards causes the locking ring to move downwards. After the ball is compressed, it will compress the spring and retract into the telescopic hole, causing the locking ring and the outer shell to separate from the water outlet pipe. At this time, the filter element can be replaced together with the outer shell, or the filter element can be replaced after unscrewing the locking sleeve. When installing the filter element, the sealing sleeve must first be placed on the outer shell, then the filter element is placed inside the outer shell, and then the locking sleeve is screwed into the outer shell and fixed with the outer shell threads. The process involves several steps: first, connecting the filter element by pressing the locking ring against it; second, inserting the outer casing into the outlet pipe, causing the sealing sleeve to contact the outlet pipe and the fixing ring for a sealing effect; and third, when the outer casing is inside the outlet pipe, aligning the expansion hole with the slot, inserting the ball into the slot to contact the outlet pipe for a pre-locking effect; and fourth, screwing the mounting sleeve into the outlet pipe for a threaded connection, causing the mounting ring to press against the locking ring for a fixed connection, thus completing the filter element installation. The filter element installation and replacement process involves numerous steps and is complex, making it difficult for users to quickly replace and maintain the filter element.

[0027] 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.

[0028] Example 1:

[0029] A kitchen faucet with a quick-release filter structure, such as Figures 1 to 6 As shown, it includes the faucet body 1, the water outlet pipe 2, the aerator 3, and the filter element 4.

[0030] The water outlet pipe 2 is rotatably connected to the faucet body 1. Specifically, the inlet end of the water outlet pipe 2 is threaded with a connector 13, and the faucet body 1 is threaded with a connector cap 14. The connector 13 passes through the connector cap 14, and the end of the connector 13 is located inside the faucet body 1. The connector cap 14 is used to limit the connector 13 along the axial direction, thereby preventing the connector 13 from detaching from the faucet body 1. The connector 13 can rotate relative to the faucet body 1. That is, when the user rotates the water outlet pipe 2 with external force, the water outlet pipe 2 drives the connector 13 to rotate relative to the faucet body 1, thereby adjusting the water outlet position and improving the ease of use of the faucet.

[0031] Specifically, the connector cap 14 is provided with a positioning step 15 on the connector 13. The inner bottom surface of the connector cap 14 abuts against the step surface of the positioning step 15. The abutting action of the two achieves the limitation of the connector 13.

[0032] The inlet end of the water outlet pipe 2 abuts against the upper end face of the connecting cap 14 to ensure a stable relative position between the water outlet pipe 2 and the connecting cap 14, facilitating assembly.

[0033] An annular flange 19 is provided inside the water outlet pipe 2, and a filter screen 20 is detachably installed inside the water outlet pipe 2. The connector 13 presses the filter screen 20 tightly onto the end face of the annular flange 19, which can effectively ensure the stability of the filter screen 20. Moreover, when disassembling and assembling the filter screen 20, it is only necessary to rotate the connector cap 14 by external force to release its threaded connection with the faucet body 1, and then rotate the connector 13 by external force to release its threaded connection with the water outlet pipe 2, so that the filter screen 20 can be removed from the water outlet pipe 2.

[0034] During assembly, first place the filter screen 20 into the water outlet pipe 2, then pass the connector 13 through the connector cap 14 and thread it to the water inlet end of the water outlet pipe 2 until the connector 13 presses the filter screen 20 tightly onto the end face of the annular flange 19. Then insert the connector 13 into the faucet body 1 and complete the threaded connection between the connector cap 14 and the faucet body 1. The operation is simple, the assembly is convenient, and it is also convenient to disassemble and maintain the filter screen 20.

[0035] Furthermore, the outer wall of the connecting cap 14 is provided with several arc-shaped force grooves 21. The arc-shaped force grooves 21 serve as force points, making it convenient for users to rotate the connecting cap 14 for assembly and disassembly.

[0036] The main body 1 of the faucet is provided with a support step 16. A sealing ring 17 is provided between the lower end face of the connecting cap 14 and the step surface of the support step 16. The sealing ring 17 is restricted by the support step 16 and the connecting cap 14, thereby ensuring the stability of the sealing ring 17 and thus ensuring the reliability of the seal.

[0037] A sealing protrusion 18 extends from the outer wall of the connector 13. The sealing protrusion 18 seals the outer wall of the connector 13 with the inner wall of the faucet body 1. The double seal of the sealing protrusion 18 and the sealing ring 17 further ensures the airtightness and prevents leakage.

[0038] The aerator 3 is detachably installed inside the outlet end of the water outlet pipe 2. The outlet end of the water outlet pipe 2 is provided with a limiting step 5 for limiting the position of the aerator 3. The limiting step 5 restricts the position of the aerator 3 to ensure the stability of the position of the aerator 3.

[0039] The aerator 3 is provided with a receiving groove 6, and the filter element 4 is placed in the receiving groove 6. The upper surface of the filter element 4 abuts against the step surface of the limiting step 5, and the lower surface of the filter element 4 abuts against the bottom of the receiving groove 6, thereby ensuring the stability of the filter element 4.

[0040] The water in the outlet pipe 2 flows through the filter screen 20, the filter element 4 and the aerator 3 in sequence. The filter screen 20 filters the water passing through the outlet pipe 2, trapping large particles of impurities in the water. The filter element 4 adsorbs small particles, thereby improving the purity of the water.

[0041] Two opposing slots 7 are provided inside the outlet end of the water pipe 2. The slots 7 are "L" shaped. Two opposing connecting blocks 8 are provided on the outer wall of the aerator 3. When the aerator 3 is rotated and moved downward, the two connecting blocks 8 can be disengaged from the corresponding slots 7 respectively. When the aerator 3 is moved upward and rotated, the two connecting blocks 8 can be locked in the corresponding slots 7 respectively.

[0042] Both slots 7 are provided with positioning protrusions 9, which are used to limit the connection block 8. When the bubbler 3 is rotated, the connection block 8 can pass through the positioning protrusions 9.

[0043] When the connecting block 8 is locked in the slot 7, one side of the connecting block 8 abuts against the side wall of the slot 7, and the other side of the connecting block 8 abuts against the side wall of the positioning protrusion 9. Through the abutting action of the positioning protrusion 9, the slot 7, and the connecting block 8, the position of the connecting block 8 in the slot 7 is kept stable, thereby locking the connecting block 8, that is, the positioning protrusion 9 restricts the connecting block 8 from leaving the slot 7.

[0044] The positioning protrusion 9 is provided with a guide arc surface 12 for guiding the connecting block 8. Through the guiding effect of the guide arc surface 12, the connecting block 8 can pass through the positioning protrusion 9 more easily, that is, the assembly and disassembly of the bubbler 3 is more labor-saving and convenient.

[0045] During disassembly, simply rotate and then move the aerator 3 downwards using external force to disengage the two connecting blocks 8 from their respective slots 7, and then remove the aerator 3. Then, remove the filter element 4 from the receiving slot 6 for replacement. During installation, align the connecting block 8 with the entrance of the slot 7, then move and rotate the aerator 3 upwards using external force to allow the connecting block 8 to pass through the positioning protrusion 9 until one side of the connecting block 8 abuts against the side wall of the slot 7 and the other side of the connecting block 8 abuts against the side wall of the positioning protrusion 9.

[0046] Example 2:

[0047] The difference between Example 2 and Example 1 is that, as Figures 7 to 8 As shown, each of the two slots 7 has a magnetic block 10 embedded in it, and each of the two connecting blocks 8 has a magnetic block 21 embedded in it. Magnetic blocks 10 and 21 are magnetically attracted to each other. Through the magnetic attraction between magnetic blocks 10 and 21, the connecting block 8 is prevented from leaving the slot 7, thus locking the connecting block 8 in the slot 7. At this time, magnetic block 10 is aligned with magnetic block 21. When disassembling the bubbler 3, it is only necessary to overcome the magnetic attraction between magnetic blocks 10 and 21 by external force, so that the connecting block 8 can leave the slot 7.

[0048] The specific embodiments described herein are merely illustrative examples of the spirit of this utility model; those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
