Simultaneously, the handle moves the rotating rod, which in turn moves the piston rod upward, causing the sealing block to move upward, opening the water outlet. Water enters the water chamber through the outlet, then flows into the flow path, passes through the filter screen, and enters the water outlet pipe, achieving the purpose of water filtration. After using the water, turning the handle again closes the water outlet, moving the connecting rod downward. The connecting rod moves the filter plate downward, ultimately positioning it in the sediment chamber. During the up-and-down movement of the filter plate, the cleaning mechanism cleans the filter screen, removing impurities that fall into the sediment box. Cleaning is simple: just remove the sediment box, clean it, and then reinstall it. Using a bathroom faucet with this structure keeps the filter screen clean and prevents clogging, extending the filter screen's lifespan without affecting the user's access to tap water.

[0026] Reference Figure 1-6 As shown, the bathroom faucet with self-cleaning function according to this utility model includes a shell 1, a handle 2 on the shell 1, a water outlet pipe 3 fixed on the shell 1, a water-containing cavity 4 inside the shell 1, a passage 5 on the shell 1 for connecting the water outlet pipe 3 and the water-containing cavity 4, a water outlet switch 6 inside the shell 1, a filter device 7 inside the shell 1, a water outlet hole 8 on the shell 1, and a hollow ball 9 on the shell 1. The filter device 7 includes a connecting rod 71 rotatably mounted on the handle 2 at one end, a filter plate 72 rotatably mounted on the other end of the connecting rod 71, a filter screen 73 fixed on the filter plate 72, a container cavity 74 inside the shell 1, two sealing plates 75 fixed on the shell 1, a cleaning mechanism 76 inside the shell 1 for cleaning the filter screen 73, and a detachable impurity box on the shell. The handle 2 and the hollow ball 9 are tightly fitted together.

[0027] Specifically, the water outlet switch 6 includes a rotating rod 61 rotatably mounted on the handle 2, a piston rod 62 movably mounted inside the housing 1, and a sealing block 63 fixedly mounted on one end of the piston rod 62; the other end of the piston rod 62 is rotatably connected to the other end of the rotating rod 61; and the sealing block 63 is located inside the water-containing cavity 4.

[0028] When using the faucet, turn the handle 2. The handle 2 is tightly fitted with the hollow ball 9, which keeps the handle 2 in one position. The handle 2 drives the connecting rod 71 to move, and the connecting rod 71 drives the filter plate 72 to move upward, so that the filter screen 73 is exactly in the passage 5. The handle 2 drives the rotating rod 61 to move, and the rotating rod 61 drives the piston rod 62 to move upward. The piston rod 62 drives the sealing block 63 to move upward, opening the water outlet 8. Water enters the water chamber 4 from the water outlet, then enters the passage 5, passes through the filter screen 73, and enters the water outlet pipe 3, thus achieving the purpose of filtering water. After using the water, the user pulls handle 2 again, causing connecting rod 71 to move downwards, which in turn moves filter plate 72 downwards. Filter plate 72 enters the container cavity 74 through passage 5. During the movement of filter plate 72, cleaning mechanism 76 cleans the filter screen, removing impurities from filter screen 73. The impurities fall into impurity box 77. To clean, simply remove impurity box 77, clean it, and then reinstall it. Using a bathroom faucet with the above structure can keep the filter screen clean and prevent clogging, thus extending the service life of the filter screen without affecting the user's use of tap water.

[0029] Specifically, the cleaning mechanism 76 includes two movable rods 761 movably mounted on the housing 1, a cleaning brush assembly 762 fixedly mounted on one end of the two movable rods 761, a lifting assembly 763 mounted inside the housing 1 for driving the two movable rods 761 to move up and down, and a reciprocating assembly 764 mounted inside the housing 1 for driving the cleaning brush 762 to move horizontally.

[0030] Specifically, the lifting assembly 763 includes two first racks 7631 disposed on both sides of the filter plate 72, two transmission rods 7632 rotatably disposed on the outer casing 1, two first gears 7633 respectively fixedly disposed on the two transmission rods 7632 and meshing with the two first racks 7631, two second racks 7634 respectively disposed on the two moving rods 761, two first intermittent gears 7635 respectively fixedly disposed on the two transmission rods 7632 and meshing with the two second racks 7634, two first springs 7636 respectively fixed at both ends on the outer casing 1 and the two moving rods 761, a fixing plate 7637 fixedly disposed on the outer casing 1, and two second springs 7638 respectively fixed at both ends on the fixing plate 7637 and the cleaning brush assembly 762.

[0031] The user pulls handle 2, causing connecting rod 71 to move upward, which in turn moves filter plate 72 upward. Filter plate 72 drives two first gears 7633 to rotate, which in turn drives two transmission rods 7632 to rotate. The two transmission rods 7632 drive two first intermittent gears 7635 to rotate. When the two first intermittent gears 7635 rotate to mesh with the two second racks 7634 respectively, they will drive two moving rods 761 to move downward, which in turn causes the cleaning brush assembly 762 to move downward, stretching the two first springs 7636 and compressing the two second springs 7636. 638. When the two first intermittent gears 7635 rotate to the point where they no longer mesh with the two second racks 7634, the two first springs 7636 contract and the two second springs 7638 rebound, driving the two moving rods 761 to move upward, which in turn drives the cleaning brush assembly 762 to move upward, enabling the cleaning brush assembly 762 to reciprocate vertically. When the filter plate 72 moves downward, the cleaning brush assembly 762 also reciprocates, meaning that the cleaning brush assembly 762 repeatedly cleans the filter screen 73 during the movement of the filter plate 72, resulting in a better cleaning effect.

[0032] Specifically, the cleaning brush assembly 762 includes a first slide groove 7621 fixedly disposed at one end of two movable rods 761, a first slider 7622 movably disposed on the first slide groove 7621, a second slide groove 7623 fixedly disposed on two second springs 7638, a first slider 7624 movably disposed on the second slide groove 7623, and a cleaning brush 7625 whose two ends are respectively fixed on the first slider 7622 and the second slider 7624.

[0033] Specifically, the reciprocating assembly 764 includes a third gear 7641 fixedly mounted on one of the transmission rods 7632, a third rack 7642 movably mounted on the housing 1 and meshing with the second gear 7641, a telescopic rod 7643 with its two ends fixedly mounted on the third rack 7642 and the cleaning brush 7615 respectively, and a third spring 7644 with its two ends fixedly mounted on the housing 1 and the third rack 7642 respectively.

[0034] The filter plate 72 moves upward, causing the two transmission rods 761 to rotate, which in turn drives the first intermittent gear 7641 to rotate. When the second intermittent gear 7641 rotates to mesh with the third rack 7642, it drives the third rack 7642 to move horizontally, stretching the third spring 7644. The third rack 7642 then drives the telescopic rod 7643 to move horizontally, which in turn drives the cleaning brush 7625 to move horizontally. When the second intermittent gear 7641 rotates to the point where it no longer meshes with the third rack 7642, the third spring 7644 contracts, causing the third rack 7642 to move in the opposite direction, which in turn drives the cleaning brush 7625 to move in the opposite direction, thus achieving the purpose of the cleaning brush 7625 reciprocating in the horizontal direction. When the filter plate 72 moves downward, the cleaning brush 7625 also reciprocates in the same way. Therefore, during the movement of the filter plate 72, the cleaning brush 7625 can simultaneously perform reciprocating motion in both the vertical and horizontal directions, allowing for repeated cleaning of the filter screen 73. This makes the filter screen 73 cleaner, less prone to clogging, and does not affect the user's daily use.
