DETAILED DESCRIPTION

[0029] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] The following will fully describe the embodiments of the present invention with reference to the accompanying drawings. It should be noted that the present invention can be implemented in different forms and is not limited to the embodiments explained herein. These embodiments are provided to make the present disclosure thorough and complete and to fully convey the scope of the present invention to those skilled in the art.

[0031] The utility model provides a faucet with a detachable filter, such as Figure 1-8 As shown, it includes a base 1, a water pipe assembly 2, a decorative cover assembly 3 and a filter element 4;

[0032] The base 1 can be a structure for fixing the faucet on a wash basin, a sink or a wall, and a water inlet cavity 5 is formed in the base 1. The water inlet cavity 5 is used to connect to a water source device. The water source device can be any existing device or system that can provide water flow, such as a household water pipe network. One end of the water inlet cavity 5 is opened to form a water pipe socket 7. Specifically, in this embodiment, the base 1 is used to be installed on the top surface of the wash basin. The water inlet cavity 5 is a cylindrical cavity extending longitudinally. A water inlet cavity water inlet 18 is opened at the bottom of the water inlet cavity 5. The water inlet cavity water inlet 18 is connected to the water source device, and the water pipe socket 7 is located at the top of the water inlet cavity 5.

[0033] The water pipe assembly 2 includes a water pipe 8 and a sealing ring 9; one end of the water pipe 8 is a water inlet end 10, and the water inlet end 10 is provided with a water pipe water inlet 11, and the other end of the water pipe 8 is provided with a water pipe water outlet 12, and the water pipe water inlet 11 and the water pipe water outlet 12 are connected through the water pipe 8; the sealing ring 9 is sleeved on the outer pipe wall of the water inlet end 10, and the water inlet end 10 can be inserted and pulled out from the water pipe socket 7 into the water inlet cavity 5, and after being inserted into the water inlet cavity 5, the sealing ring 9 is clamped between the outer wall of the water pipe 8 and the inner wall of the water inlet cavity 5, and the water pipe assembly 2 forms a sealing match with the inner wall of the water inlet cavity 5 through the sealing ring 9, so that the water flow in the water inlet cavity 5 can only flow out from the water pipe water inlet 11, and then enter the water pipe 8, and then flow out to the outside from the water pipe water outlet 12;

[0034] The decorative cover assembly 3 is cylindrical and is sleeved on the outer periphery of the water inlet end 10 of the water pipe 8. One end of the decorative cover assembly 3 is detachably mounted on the base 1. The decorative cover assembly 3 and the base 1 can be mounted on the base 1 by any existing detachable connection method such as threaded connection, screw connection, and clamping connection. The water supply pipe 8 passes through the other end of the decorative cover assembly 3. After the decorative cover assembly 3 is installed on the base 1, it is pressed against the water pipe assembly 2. Specifically, it can be the water pipe 8 of the water pipe assembly 2, or the sealing ring 9 on the water pipe assembly 2, or a push-up member 19 separately mounted on the water pipe 8, as long as it can limit the water inlet end 10 of the water pipe 8 from being pulled out of the water inlet cavity 5.

[0035] The filter element 4 can be any existing filter element, as long as it can be detachably mounted on the water pipe inlet 11, so that when it is mounted on the water pipe inlet 11, water can only enter the water pipe inlet 11 after passing through the filter element 4 for filtration. The preferred embodiment is given below.

[0036] Therefore, when the filter element needs to be removed and replaced, it is only necessary to first remove the decorative cover from the base, and then pull the water pipe assembly together with the filter element out of the water inlet cavity, and then the filter element can be removed from the water inlet of the water pipe and replaced, making the filter element more convenient to disassemble and assemble.

[0037] In order to facilitate the disassembly and assembly of the decorative cover assembly 3, it is preferred that the decorative cover assembly 3 is threadedly screwed on the base 1 so as to be detachably installed with the base 1. Specifically, the inner wall of the decorative cover assembly 3 is provided with an internal thread, and the outer wall of the base 1 is formed with an external thread. The internal thread cooperates with the external thread so that the decorative cover assembly 3 is threadedly screwed on the base 1.

[0038] Since the water pipes 8 of the basin faucets are all bent, that is, one end of the water pipe outlet 12 is bent downward, in order to be able to adjust the direction of the water pipe outlet 12, it is preferred that the decorative cover assembly 3 is rotatably sleeved on the water pipe 8, and the water pipe 8 is rotatably inserted into the water inlet cavity 5, so that the water pipe 8 and the base 1 form a rotatable connection, and then the direction of the water pipe outlet 12 can be adjusted by rotating the water pipe 8. Since the filter element 4 is installed on the water pipe inlet 11, during the adjustment process, the filter element 4 will rotate with the rotation of the water pipe 5, and the connection between the filter element 4 and the water pipe inlet 11 will not be loosened and leaked due to frequent rotation of the water pipe 8;

[0039] Since the decorative cover assembly 3 needs to push down the water pipe assembly 2, when the water pipe 8 rotates, the abutment between the decorative cover assembly 3 and the water pipe assembly 2 will be worn. Therefore, for the convenience of maintenance, the water pipe assembly 2 preferably also includes a push-pull member 19, which can be detachably installed on the outer tube wall of the water inlet end 10 of the water pipe 8, and after the push-pull member 19 is installed, it can be axially limited on the water pipe 8. After the decorative cover assembly 3 is installed on the base 1, the water inlet end 10 of the water pipe 8 is limited by pushing down the push-pull member 19 to be pulled out of the water inlet cavity 5. After wear, the push-pull member 19 can be replaced. The more specific structure of the push-pull member 19 is not limited. Specifically in this embodiment, the push-pull member 19 is a C-shaped elastic clamping ring, and the outer tube wall of the water pipe 8 is provided with a ring groove for its sleeve and clamping;

[0040] To facilitate replacement of easily worn parts on the decorative cover assembly 3, the decorative cover assembly 3 includes a decorative cover body 13 and a pressure ring 14. The decorative cover body 13 is cylindrical and is sleeved on the outer periphery of the water inlet pipe 8 of the water pipe 8. One end is detachably mounted on the base 1, and the other end is for the water supply pipe 8 to pass through. The pressure ring 14 is detachably mounted in the decorative cover body 13, movably sleeved on the water pipe 8, and can rotate and move axially relative to the water pipe 8. After the decorative cover body 13 is mounted on the base 1, at least a portion of the pressure ring 14 is clamped between the inner wall of the decorative cover body 13 and the outer wall of the water pipe 8. The decorative cover body 13 presses against the pressure ring 14, and the pressure ring 14 presses against the push piece 19 to limit the water inlet end 10 of the water pipe 8 from being pulled out of the water inlet chamber 5. Therefore, when wear is caused by rotation of the water pipe 8, only the pressure ring 14 needs to be replaced.

[0041] Preferably, the sealing ring 9 is provided in plurality, and the plurality of sealing rings 9 are sequentially sleeved on the outer wall of the water pipe 8 along the axial direction of the water pipe 8, and in the direction away from the water inlet chamber 5, the size of each sealing ring 9 protruding from the water pipe 8 along the radial direction of the water pipe 8 is increasing, thereby further ensuring the sealing effect. More preferably, the position of the inner wall of the water inlet chamber 5 for cooperating with the sealing ring 9 is in the shape of a cone that gradually retracts inward toward the inner side of the water inlet chamber 5, so that when water leakage occurs between the outer wall of the water pipe 8 and the inner wall of the water inlet chamber 5 due to aging or the like, it is only necessary to continue to tighten the decorative cover assembly 3 downward, and the decorative cover assembly 3 further presses down the water pipe assembly 2, so that the interval between the outer wall of the water pipe 8 and the inner wall of the water inlet chamber 5 is further reduced, thereby further clamping the sealing ring 9, and the water seal between the outer wall of the water pipe 8 and the inner wall of the water inlet chamber 5 can be restored.

[0042] Specifically in this embodiment, a filter element inner cavity 15 is formed in the filter element 4, and a filter element side wall 16 (the side wall described here is not limited to the side outer wall of the filter element, and can also include the bottom outer wall, etc.) can allow water to flow through for filtration, and the water flow outside the filter element 4 can only reach the filter element inner cavity 15 through the filter element side wall 16, and the filter element side wall 16 can be made of any one or several existing water filtration materials, such as common PP cotton, activated carbon, etc., one side of the filter element inner cavity 15 is open to form a filter element water outlet 17, and one side of the filter element 4 where the filter element water outlet 17 is provided can be detachably plugged into the water pipe inlet 11, so that the filter element 4 can be detachably installed on the water pipe inlet 11, in order to avoid water leakage at the plug-in point, it is preferably provided with a sealing ring between the two for sealing, and, specifically in this embodiment, in order to reduce manufacturing costs, only the side wall of the filter element 4 is configured to filter water, and the bottom wall of the filter element 4 is blocked.

[0043] The above description is only a preferred embodiment of the present utility model and is not a limitation on the design of the present case. Any equivalent changes made based on the key design of the present case shall fall within the protection scope of the present case.
