[0017] The present invention will be further described and explained below in conjunction with specific embodiments and accompanying drawings:

[0018] Please refer to Figures 1 to 3 A quick-detachable filter, a filter tube 10 is sealed with a first mounting disk 11 at one end, a filter mesh group 20 is provided in the filter tube 10, one end of the filter mesh group 20 is detachably connected to the first mounting disk 11, and a second mounting disk 12 is sealed at the other end of the filter tube 10. A through opening is opened on the second mounting disk 12, and a door cover 30 is detachably and sealed at the through opening. The other end of the filter mesh group 20 is detachably connected to the door cover 30, a water inlet is opened on one side of the top of the outer peripheral wall of the filter tube 10, and a water inlet pipe 13 is provided at the water inlet. A water outlet is opened on the side of the bottom of the outer peripheral wall of the filter tube 10 away from the water inlet, and a water outlet pipe 14 is provided at the water outlet.

[0019] In the above scheme, the filter tube 10 is installed through the first mounting plate 11 and the second mounting plate 12. Water flows into the filter tube 10 from the water inlet pipe 13, flows through the filter mesh group 20 to filter impurities, and finally flows out from the water outlet pipe 14. When the filter mesh group 20 needs to be cleaned or replaced, it is only necessary to open the door cover 30, take out the filter mesh group 20 for cleaning or replacement, and at the same time flush the inside of the filter cartridge with water, and then reinstall the new filter mesh group 20 back into the inside of the filter cartridge. The maintenance efficiency is high and the use cost is low.

[0020] Please refer to Figure 2 The filter assembly 20 includes a first mounting plate 21 and a second mounting plate 22 spaced apart. A connecting rod assembly 23 is disposed between the first and second mounting plates 21, 22. A plurality of first filters 24 and a plurality of second filters 25 are mounted on the connecting rod assembly 23. The first filters 24 and the second filters 25 are arranged in an alternating pattern. Specifically, a gap is formed in the middle of the first filter 24, and the second filter 25 is disposed correspondingly to the middle of the first filter 24.

[0021] In the above solution, impurities can be filtered out when the water flows through the first filter 24 and the second filter 25. At the same time, the first filter 24 and the second filter 25 arranged at intervals can not only ensure the flow of water, but also improve the filtration quality, making the water filtered more cleanly.

[0022] Please refer to Figure 3 The first mounting plate 11 is provided with a first slot on the surface close to the filter tube 10 , and the first mounting plate 21 cooperates with the first slot. The door cover 30 is provided with a second slot 31 on the surface close to the filter tube 10 , and the second mounting plate 22 cooperates with the second slot 31 .

[0023] In the above embodiment, when installing the filter assembly 20, the first mounting plate 21 snaps into the first slot. Simultaneously, when closing the door cover 30, the second mounting plate 22 snaps into the second slot 31, thereby securing the filter assembly 20 and facilitating assembly and disassembly. In this embodiment, both the first mounting plate 21 and the second mounting plate 22 are runway-shaped, and the first and second slots 31 act as retaining bars during installation.

[0024] Specifically, the door cover 30 is detachably connected to the second mounting plate 12 by a plurality of screws 33. Furthermore, a sealing ring 32 is provided on the door cover 30 to match the inner peripheral wall of the through opening. The sealing ring 32 can improve the sealing performance of the connection between the door cover 30 and the second mounting plate 12 to prevent water leakage.

[0025] Specifically, two supports 15 are provided at intervals on the bottom of the outer peripheral wall of the filter tube 10 , which can support the filter tube 10 and improve the bearing capacity.

[0026] The utility model provides a quick-detachable filter, in which the filter tube is installed through a first mounting plate and a second mounting plate, water flows into the filter tube from the water inlet pipe, flows through the filter mesh group to filter impurities, and finally flows out from the water outlet pipe. When the filter mesh group needs to be cleaned or replaced, it is only necessary to open the door cover, take out the filter mesh group for cleaning or replacement, and at the same time flush the inside of the filter cartridge with water to clean it, and then reinstall the new filter mesh group into the inside of the filter cartridge, which has high maintenance efficiency and low use cost.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
