Description

Technical Field

[0001] The utility model relates to the technical field of filtering faucets, in particular to a filtering faucet which is convenient for replacing a filter element. Background Art

[0002] The filtered faucet monitors the change of the pressure difference between the inlet and outlet through the pressure difference switch. When the pressure difference reaches the set value, the electronic controller gives the hydraulic control valve and drives the motor signal.

[0003] For example, the authorization announcement number is "CN220505929U", which is a filtering faucet that is easy to replace the filter element. A double-layer filter is detachably connected in the water outlet pipe, and the double-layer filter includes an inner sleeve and an outer sleeve. The inner sleeve is located in the water outlet pipe, and a sliding groove that runs through the lower end of the water outlet pipe is opened in the side wall of the water outlet pipe. The outer sleeve is slidably connected in the sliding groove. A fixing mechanism for fixing the double-layer filter is provided between the outer sleeve and the water outlet pipe. The structure is simple, and disassembly and assembly are convenient. Quick disassembly and assembly can be achieved without auxiliary tools such as screwdrivers. However, when the filtering faucet is used, the filter will move downward a distance due to the sliding groove after installation. When the filter is blocked, water will accumulate at the water outlet, causing the water level to rise. The water overflows through the gap between the filter and the water nozzle. The increased water pressure will cause the water to shoot out at the gap, which needs to be cleaned later, reducing the sealing performance of the filtering faucet and affecting the normal use of the filtering faucet. Summary of the invention

[0020] The utility model is further described below in conjunction with the accompanying drawings: Embodiment 1:

[0021] See also Figure 1-6 In the present embodiment, a filtering faucet which is convenient for replacing a filter element comprises a faucet 1 and a collar 4. The outer wall of the faucet 1 is plugged into the inner wall of the collar 4. The model of the faucet 1 needs to be selected according to usage requirements. A vertical pipe 5 is fixedly connected to the outer wall of the collar 4. The collar 4 is a rubber ring that serves as a connection seal. A threaded pipe 6 is connected to the bottom of the vertical pipe 5. A filtering structure 2 is connected to the outer wall of the threaded pipe 6. A screw 7 is fixedly connected to the top right side of the vertical pipe 5. A reinforcement structure 3 is connected above the outer wall of the screw 7. The inner wall of the reinforcement structure 3 fits the outer wall of the faucet 1.

[0022] The filtering structure 2 includes a cylinder 201 and a round pad 202. The inner wall of the cylinder 201 is threadedly connected to the outer wall of the threaded tube 6. The cylinder 201 is subjected to force to rotate up and down through the outer wall of the threaded tube 6. The bottom of the inner wall of the cylinder 201 is fixedly connected to the bottom of the round pad 202. The round pad 202 is made of rubber. The through hole in the middle ensures that the raw water passes normally. The inner side of the top of the round pad 202 is fixedly connected with a filter element 203. The filter element 203 is PP cotton. The outer wall of the filter element 203 is plugged into the inner wall of the threaded tube 6. The outer wall of the round pad 202 fits the bottom of the outer wall of the cylinder 201.

[0023] Through the filtering structure 2, the cylinder 201 is rotated downward on the outer wall of the threaded tube 6 until the cylinder 201 is separated from the threaded tube 6, and then the cylinder 201 is turned downward to make the filter element 203 and the round pad 202 fall out, and then the new filter element 203 and the round pad 202 are inserted into the cylinder 201, so that the inner wall of the cylinder 201 is threadedly connected with the outer wall of the threaded tube 6 until the cylinder 201 cannot be screwed. At this time, the bottom of the threaded tube 6 is tightly pressed against the top of the round pad 202, and the round pad 202 plays a sealing role through the rubber material, which makes it easy to replace the filter element 203 of the filtering faucet, ensures the sealing performance of the filtering faucet, and ensures the normal use of the filtering faucet.

[0024] The reinforcement structure 3 includes a protruding rod 301 and a circular ring 302. The inner wall of the protruding rod 301 is threadedly connected to the outer wall of the screw rod 7. The protruding rod 301 can rotate up and down on the outer wall of the screw rod 7. The top of the outer wall of the protruding rod 301 is rotatably connected to the inner wall of the circular ring 302. The top of the outer wall of the protruding rod 301 is subjected to force to rotate through the bearing on the inner wall of the circular ring 302. An arc plate 303 is fixedly connected to the left side of the circular ring 302. The arc plate 303 can be adjusted to the highest position to prevent the filter structure 2 from conflicting with the position of the faucet 1 during installation. The inner wall of the arc plate 303 fits with the outer wall of the faucet 1.

[0025] Working principle:

[0026] The water source of the faucet 1 enters the vertical pipe 5 through the water nozzle, and then enters the cylinder 201 through the threaded pipe 6. The filter element 203 inside the cylinder 201 filters the water source, and finally the water source is discharged at the bottom of the cylinder 201.

[0027] Filter faucet installation reinforcement:

[0028] The inner wall of the vertical pipe 5 is inserted into the water spout of the faucet 1 from bottom to top. At this time, the ring 4 will be clamped between the vertical pipe 5 and the water spout. The ring 4 plays a sealing role through its own rubber material. After the vertical pipe 5 is plugged into the faucet 1, the arc plate 303 is located above the outer wall of the faucet 1 and fits in. At this time, the protruding rod 301 is rotated downward on the outer wall of the screw rod 7. Since the top of the outer wall of the protruding rod 301 is rotationally connected with the inner wall of the circular ring 302, the circular ring 302 will move downward with the protruding rod 301. The moving circular ring 302 moves downward with the arc plate 303 against the outer wall of the faucet 1 until the bottom of the arc plate 303 is tightly against the top of the water spout of the faucet 1, completing the installation and reinforcement of the filtering structure 2.

[0029] Filter faucet filter replacement:

[0030] The cylinder 201 is rotated downward on the outer wall of the threaded tube 6 until the cylinder 201 is separated from the threaded tube 6, and then the cylinder 201 is turned downward to make the filter element 203 and the round pad 202 fall out, and then a new filter element 203 and the round pad 202 are inserted into the cylinder 201, so that the inner wall of the cylinder 201 is threadedly connected with the outer wall of the threaded tube 6 until the cylinder 201 cannot be screwed. At this time, the bottom of the threaded tube 6 is tightly pressed against the top of the round pad 202, and the round pad 202 plays a sealing role through the rubber material, which facilitates the replacement of the filter element 203 of the filtering faucet, and the round pad 202 plays a sealing role through its own rubber material. Embodiment 2:

[0031] See also Figure 1-6 In this embodiment, the filtering structure 2 further includes a curved block 2a1, and the inner sides of the two curved blocks 2a1 are respectively fixedly connected to the left and right sides of the cylinder 201.

[0032] Working principle:

[0033] If slippage occurs when the cylinder 201 is rotated, two fingers can be stuck on the curved block 2a1, and then the fingers can exert force to cooperate with the curved block 201 to make the cylinder 201 rotate on the outer wall of the threaded tube 6.

[0034] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
