[0023] The following further describes the embodiments of the present utility model in conjunction with the accompanying drawings.

[0024] Embodiment:

[0025] As Figures 1 - 4As shown in the figure, a scale-inhibiting reverse osmosis water purifier includes a filtering component, a vibration component and a water purification component 60. The filtering component includes a water tank 10, a support drawer 20 and a filter screen 30. The top of the water tank 10 is provided with a water inlet pipe, which includes a main pipe 11 and branch pipes 12 corresponding to the number of filter screens 30 on the main pipe 11. The ends of the branch pipes 12 are respectively aligned with each filter screen 30. The bottom is provided with a water outlet pipe 13. A pull-out port matching the support drawer 20 is opened on one side wall of the water tank 10. The support drawer 20 passes through the pull-out port and forms a drawer-type connection with the inner side wall of the water tank 10. A sealing ring for sealingly connecting the support drawer 20 can be arranged at the pull-out port, and a handle 21 convenient for pulling can be arranged on the outer side of the support drawer 20. A water passing port penetrating up and down is arranged in the middle of the support drawer 20. A plurality of partition plates 22 are arranged at intervals in the water passing port, dividing the water passing port into a plurality of installation cavities 23. The filter screen 30 includes a plurality of inverted trapezoids with a wider top and a narrower bottom, and are respectively lapped in the installation cavities 23. Among them, a lapping edge is arranged at the top edge of the filter screen 30, and lapping grooves matching the lapping edge are respectively reserved at the partition plates 22 and the edges of the water passing port, ensuring that after the filter screen 30 is lapped, the top is flush with the pull-out drawer, facilitating the smooth extraction of the pull-out drawer from the pull-out port. The vibration component includes a housing 41, a motor 42, a transmission shaft 43 and a cam lifting mechanism 50. The housing 41 is arranged in the middle of the bottom of the support drawer 20 and is respectively connected to the inner wall of the water tank 10 at both ends. The width of the housing 41 is smaller than that of the water passing port, facilitating water to pass through the filter screen 30. The motor 42 is arranged at one end inside the housing 41 and is in transmission connection with the transmission shaft 43. The other end of the transmission shaft 43 is rotatably connected to the side wall of the housing 41. The cam lifting mechanism 50 is arranged on the transmission shaft 43 and is aligned with the bottom of the filter screen 30. The cam lifting mechanism 50 includes a cam 51, a contact member 52, a push rod 53, a top block 54, a limit frame 55 and a limit sleeve 56. The cam 51 is sleeved on the transmission shaft 43. The contact member 52 is attached to the top of the cam 51 and is arranged on the top of the cam 51. The push rod 53 is arranged on the top of the contact member 52. The top block 54 is arranged at the top end of the push rod 53. The limit sleeve 56 is sleeved in the middle of the push rod 53 and is arranged on the limit frame 55. The limit frame 55 is connected to the inner wall of the housing 41. When the top block 54 runs to the highest position, it can just collide with the top wall of the housing 41. The water purification component 60 selects an existing reverse osmosis filtration structure and is connected to the water outlet pipe 13 for purifying water.

[0026] The working principle of the above technical solution is as follows:

[0027] During use, water from the water source enters through the water inlet pipe and flows into each branch pipe 12 from the main pipe 11. When flowing through the filter screen 30, the water can be evenly distributed. The water passing through the filter screen 30 flows to the bottom of the water tank 10 from a position outside the housing 41 and enters the water purification component 60 through the water outlet pipe 13 for multi-layer filtration. The debris blocked on the filter screen 30 is distributed on its inclined surface and bottom surface. The motor 42 can be started to drive the transmission shaft 43 to rotate. The cam 51 on the transmission shaft 43 rotates and contacts the contact member 52. Under the action of the limit sleeve 56 on the limit frame 55, the ejector rod 53 and the ejector block 54 make repeated up-and-down movements. When the ejector block 54 contacts the top wall of the housing 41, it impacts and generates vibrations, vibrating each filter screen 30 respectively, and vibrating the debris on the inclined surface of the filter screen 30 to fall to the bottom surface of the filter screen 30 for concentration. After use, the handle 21 of the support drawer 20 can be pulled to pull out the support drawer 20, which is convenient for handling the concentrated debris.

[0028] In another embodiment, as Figure 4 shown, the contact member 52 is selected as a roller. This reduces the friction with the cam 51 and ensures the service life.

[0029] In another embodiment, as Figure 1 shown, a bearing seat 44 for supporting the transmission shaft 43 is provided at the inner bottom of the housing 41 between two adjacent cams 51. This ensures the stability of the movement of the transmission shaft 43.

[0030] In another embodiment, as Figure 4 shown, a rubber pad 57 can be provided on the top of the ejector block 54. This reduces the impact wear between the ejector block 54 and the top wall of the housing 41.

[0031] The above-described embodiments only represent the specific implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
