DETAILED DESCRIPTION

[0020] A self-cleaning filter core of a water purifier

[0021] As shown in Figure 1 , 2 the embodiment, a device shell 1 and a filter core cylinder 2 are included, the filter core cylinder 2 is arranged in the device shell 1, an outer sealing cover 8 is arranged on the upper end of the device shell 1, a water inlet pipe 7 is fixedly penetrated through the upper end of the outer sealing cover 8, a water outlet valve 26 is communicated with the lower left end of the device shell 1, a lower butt joint pipe 11 is fixedly penetrated through the right side of the upper end of an inner sealing cover 9, a sealing ring 16 is connected to the upper end of the lower butt joint pipe 11, an elastic pipe 10 is communicated with the lower end of the water inlet pipe 7, an upper butt joint pipe 12 is communicated with the lower end of the elastic pipe 10, the upper butt joint pipe 12 is sleeved on the upper end of the outer periphery of the lower butt joint pipe 11, spring elastic rods 13 are fixedly arranged on both sides of the upper end of the upper butt joint pipe 12, the upper ends of the spring elastic rods 13 are connected to the lower end of the water inlet pipe 7, a pressing block 15 is fixedly arranged on the right side of the upper butt joint pipe 12, and a threaded pressing rod 14 is arranged on the outer sealing cover 8 above the pressing block 15.

[0022] When water is filtered through the filter core, the water enters the elastic pipe 10, the upper butt joint pipe 12, the lower butt joint pipe 11 and the filter core cylinder 2 through the water inlet pipe 7, and then the water is filtered by the filter core cylinder 2, and the filtered water is discharged for use through the water outlet valve 26. The sealing ring 16 is arranged at the joint of the upper butt joint pipe 12 and the lower butt joint pipe 11, at this time, the spring elastic rods 13 press the upper butt joint pipe 12 downward by the elastic force, so that the upper butt joint pipe 12 is pressed tightly on the sealing ring 16 of the lower butt joint pipe 11, thereby ensuring the sealing property of the upper butt joint pipe 12 sleeved on the lower butt joint pipe 11. When the upper butt joint pipe 12 is sleeved on the upper end of the outer periphery of the lower butt joint pipe 11, the threaded pressing rod 14 is screwed downward, and the threaded pressing rod 14 presses the pressing block 15 downward, thereby avoiding the loosening of the upper butt joint pipe 12 on the lower butt joint pipe 11, and better ensuring the tightness of the connection between the upper butt joint pipe 12 and the lower butt joint pipe 11.

[0023] As shown in Figure 1As shown, in this embodiment, the filter cartridge 2 is provided with a shaft tube 22. A cleaning brush 25 is fixed on the left side of the shaft tube 22, and several upwardly inclined nozzles 24 are connected to the right side of the shaft tube 22. The upper end of the filter cartridge 2 is covered with an inner sealing cover 9, and a sealing cover 17 is fixed to the upper end of the inner sealing cover 9. The shaft tube 22 rotates through the inner sealing cover 9 and the sealing cover 17 in sequence. A water pump 18 is fixed to the left side of the sealing cover 17, and the water pump 18 has a water inlet connected to a downwardly extending water pipe 19. The outlet of 8 is connected to a water supply pipe 27. The upper end of the shaft tube 22 is rotatably connected to and communicates with the water supply pipe 27. The sealing cover 17 is provided with a rotary drive assembly, which includes a motor 20, a main gear 21 and a secondary gear 23. The motor 20 is fixed to the upper end of the inner sealing cover 9. The main gear 21 is connected to the power end of the motor 20. The secondary gear 23 is fixedly sleeved on the outside of the shaft tube 22. The main gear 21 and the secondary gear 23 mesh. The side of the cleaning brush 25 contacts the inner wall of the filter cartridge 2.

[0024] When it is necessary to clean the impurities on the inner wall of the filter cartridge 2, the operation of the motor 20 drives the main gear 21, the auxiliary gear 23, the shaft tube 22, the nozzle 24, and the cleaning brush 25 to rotate. This allows the cleaning brush 25 to easily sweep and clean the impurities on the inner wall of the filter cartridge 2. The water pump 18 is then started, and water from the housing 1 is pumped into the water supply pipe 27, the shaft tube 22, and the nozzle 24 through the water pumping pipe 19. Since the nozzle 24 can rotate with the shaft tube 22, the water is sprayed onto the inner wall of the filter cartridge 2, effectively flushing the inner wall of the filter cartridge 2. Combined with the sweeping and cleaning of the filter cartridge 2 by the cleaning brush 25, the inner wall of the filter cartridge 2 is cleaned more thoroughly. In summary, this effectively reduces the hassle of disassembling and cleaning the filter cartridge 2 and improves the convenience of cleaning the filter cartridge 2.

[0025] like Figure 1 As shown, in this embodiment, the lower end of the filter cartridge 2 is connected to a water collection hopper 3, the lower end of the water collection hopper 3 is connected to an external threaded pipe 4, an internal threaded pipe 5 is fixedly inserted through the middle of the lower end of the housing 1, the external threaded pipe 4 and the internal threaded pipe 5 are threadedly connected, and a sealing ring is provided at the connection between the external threaded pipe 4 and the internal threaded pipe 5, and a wastewater valve 6 is installed at the lower end of the internal threaded pipe 5.

[0026] When it is necessary to discharge the wastewater containing impurities from the filter cartridge 2, the outlet valve 26 is closed and the wastewater valve 6 is opened. The wastewater containing impurities enters the external threaded pipe 4 and the internal threaded pipe 5 through the water collection hopper 3. Therefore, the wastewater can be easily discharged from the internal threaded pipe 5 through the wastewater valve 6. Moreover, a sealing ring is set at the connection between the external threaded pipe 4 and the internal threaded pipe 5 to ensure the sealing of the connection between the external threaded pipe 4 and the internal threaded pipe 5.

[0027] like Figure 1 , 3As shown, in this embodiment, the outer sealing cover 8 is fixed with the casing 1 by bolts, and the inner sealing cover 9 is fixed with the filter core cylinder 2 by bolts.

[0028] When the cleaning brush 25 needs to be cleaned and maintained, the bolts on the outer sealing cover 8 and the inner sealing cover 9 are removed, and then the outer sealing cover 8 and the inner sealing cover 9 can be conveniently removed. When the outer sealing cover 8 is removed upwards, the upper butt joint pipe 12 is moved away from the lower butt joint pipe 11, and when the inner sealing cover 9 is removed upwards, the shaft pipe 22 and the cleaning brush 25 can be conveniently moved out of the filter core cylinder 2. Therefore, the cleaning brush 25 can be conveniently cleaned and maintained, and the filter core cylinder 2 is rotated to drive the water collecting hopper 3 and the outer threaded pipe 4 to rotate, and the outer threaded pipe 4 is separated from the inner threaded pipe 5 in a threaded manner. Therefore, the filter core cylinder 2 can be conveniently removed from the casing 1, so that the damaged filter core cylinder 2 can be conveniently replaced and maintained.
