[0028] Example

[0029] like Figures 1-4 As shown, a water filter according to this application includes:

[0030] The screen 1 has multiple screen holes 11 for the first filtration of water; the screen 1 is circular and the multiple screen holes 11 are strips with their ends pointing to the center of the circle.

[0031] Sandbox 2 is disposed on the water outlet side of the sieve plate 1, with the water inlet side of the sandbox 2 facing the water outlet side of the sieve plate 1. The water inlet side of the sandbox 2 is provided with a first mesh 21 for second filtration of the water, and the first mesh 21 is facing the plurality of sieve holes 11. The interior of the sandbox 2 is provided with sand for third filtration of the water, and the water outlet side of the sandbox 2 is provided with a second mesh 22 for fourth filtration of the water.

[0032] Specifically, the sandbox 2 is equipped with a partition 23, which divides the internal space of the sandbox 2 into a vortex-shaped filtration channel. One end of the filtration channel faces the second mesh 22, and the other end faces the first mesh 21. By setting the partition, this application increases the length of the filtration channel, forcing water to flow from one end of the filtration channel to the other, increasing the contact time between the water and the sand, thereby enhancing the filtration effect.

[0033] The housing 3 has a sand box 2 disposed inside it. The sieve plate 1 is detachably connected to the opening of the housing 3. The sand box 2 is fixed between the sieve plate 1 and the housing 3. The housing 3 is provided with a water outlet 31 that is directly opposite the second mesh 22. The water outlet 31 is used to discharge filtered water.

[0034] Specifically, the inner wall of the opening of the housing 3 is provided with a plurality of screw grooves 32, and the edge of the screen 1 is provided with a plurality of screws 12 that match the screw grooves 32. The screen 1 and the opening of the housing 3 are detachably connected through the screw grooves 32 and the screws 12.

[0035] The screw groove 32 is an L-shaped groove provided on the inner wall of the opening of the housing 3. The screw 12 slides to the first part of the screw groove 32 and is rotated to slide to the second part of the screw groove 32. The first part is perpendicular to the second part.

[0036] During installation, the buckle 12 is aligned with the first part of the buckle groove 32 and pushed into the starting point of the second part. Then, the screen plate 1 is rotated to screw the buckle 12 into the second part of the buckle groove 32, thereby locking the screen plate 1 at the opening of the housing.

[0037] The screen plate 1 is provided with a knob 13 on the water inlet side. The end of the knob 13 is provided with an indicator inscription for indicating the rotation direction. By setting the knob 13, this application makes it easier for users to rotate the screen plate 1.

Users can know which rotation direction is the tightening direction and which rotation direction is the direction to remove the screen plate 1 from the opening of the housing 3 according to the indicator inscription.

[0038] In one embodiment of this application, the sandbox 2 is further provided with an annular first sealing rib 24 surrounding the second mesh 22 on the water outlet side, and a second sealing rib 33 is provided at a corresponding position on the inner side of the housing 3. The first sealing rib 24 and the second sealing rib 33 are engaged to seal the connection between the second mesh 22 and the water outlet 31.

[0039] Specifically, the first sealing rib 23 is provided with a groove. When the first sealing rib 24 and the second sealing rib 33 are engaged, the second sealing rib 33 is engaged into the groove, thereby achieving engagement. By engaging the first sealing rib 24 and the second sealing rib 33, the connection between the second mesh 22 and the water outlet 31 can be effectively sealed, preventing water from leaking into the housing 3.

[0040] This application discloses a water filter comprising a screen, a sandbox, and a housing. The filter performs a first filtration of water through the screen openings on the screen. The filtered water then enters through the first mesh opening of the sandbox for a second filtration. The sand inside the sandbox further filters the water a third time. Finally, the water exits through the second mesh opening of the sandbox, achieving a fourth filtration, and is discharged from the outlet of the housing. The screen and housing are detachably connected, with the sandbox fixed between them. After prolonged use, the sandbox can be removed by disassembling the screen, facilitating cleaning of both the sandbox and screen. Furthermore, this application uses sand for water filtration, resulting in lower sand replacement costs and suitability for large-scale applications.

[0041] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application.
