Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] Please refer to Figures 1-7 The utility model discloses a kind of filter core filter without disassembling pipe, including filter 1, the filter 1 including the inside of filter cartridge 11 is provided with central flow guide pipe 13 and several filter cores 12, one end of the filter cartridge 11 is detachably connected with cover 16.

[0027] Specifically, several filter cores 12 are annularly distributed outside the central flow guide pipe 13, and an air permeation gap 2 is arranged between adjacent two filter cores 12, the central flow guide pipe 13 is coaxially arranged with the filter cartridge 11, and an air permeation space 3 is arranged between the central flow guide pipe 13 and the filter core 12.

[0028] In the embodiment, the annular layout makes the water flow uniformly pass through the surface of all filter cores 12, the filtration area is increased compared with the vertically distributed filter cores 12, the filtration efficiency is improved, the air permeation gap 2 avoids the blockage between filter cores 12 due to impurity accumulation, prolongs the cleaning cycle, the central flow guide pipe 13 forms a high-speed water flow channel, the flow rate is improved, the air permeation space 3 assists the filter core 12 to filter, and reduces the blockage.

[0029] Specifically, the central flow guide pipe 13 is provided with a filter core head 14 and a filter core sealing head 19 at both ends respectively, the filter core head 14 is provided with a water inlet nozzle 15 coaxially arranged with the central flow guide pipe 13 on the side away from the central flow guide pipe 13.

[0030] In the embodiment, the inside of the filter head 14 is provided with a hole position in communication with the filter element 12, and the filter sealing head 19 is used to block water in the inside of the filter cartridge 11. The water filtered by the filter element 12 enters the inside of the cover 16 through the filter head 14, and the water in the inside of the cover 16 enters the central flow guide pipe 13 through the water inlet nozzle 15 and is discharged at high speed. The end of the water inlet nozzle 15 away from the filter head 14 is in a trumpet shape, which can guide the water flow and control the water inlet rate.

[0031] Specifically, the opposite ends of the filter cartridge 11 and the cover 16 are both provided with annular sealing grooves 18, and the inner circles of the two sealing grooves 18 are jointly provided with a sealing ring one 181 which is in abutment with the outside of the filter head 14. The outside of the filter sealing head 19 is provided with a sealing ring two 191.

[0032] In the embodiment, the sealing grooves 18 not only limit the sealing ring one 181 and prevent unfiltered water from flowing out through the gap between the filter head 14 and the filter cartridge 11, but also ensure the sealing of the connection between the filter cartridge 11 and the cover 16, and provide a mounting position for the clamp 17. The two sealing grooves 18 are combined in a semicircular shape, and the sealing ring two 191 is used to seal between the filter sealing head 19 and the filter cartridge 11.

[0033] Specifically, the outer circles of the two sealing grooves 18 are jointly provided with the clamp 17, and the clamp 17 includes two semicircular clamps which are hingedly connected at one end and locked at the other end by a locking screw 171 and a locking nut 172.

[0034] In the embodiment, the design that the two semicircular clamps are hingedly connected at one end shortens the disassembly and assembly time. The inner walls of the two semicircular clamps are both provided with inclined surfaces. This design makes the two semicircular clamps abut against the sealing grooves 18, which exerts a relative moving force on the two sealing grooves 18, so that the two sealing grooves 18 further press the sealing ring one 181, thereby further ensuring the sealing of the connection between the filter cartridge 11 and the cover 16. The end of one of the semicircular clamps away from the hinged connection is hingedly connected to the locking screw 171, the locking screw 171 is threadedly provided with the locking nut 172, the locking nut 172 is provided with a butterfly handle, and rotating the locking nut 172 abuts against the other semicircular clamp. The two semicircular clamps are relatively moved away from the hinged connection, so that the clamp 17 tightly holds the two sealing grooves 18. When replacing the filter element 12, the locking nut 172 is loosened to open the clamp 17, the cover 16 is disassembled, the filter element 12 is replaced, and the effect of later maintenance is greatly improved.

[0035] Specifically, the top of the filter cartridge 11 is provided with a water inlet 111 and a water outlet 112. The water inlet 111 is located above the side of the filter head 14 away from the water inlet nozzle 15, and the water outlet 112 is located above the side of the filter sealing head 19 away from the central pipe flow guide.

[0036] In the embodiment, the water to be filtered enters the inside of the filter cartridge 11 through the water inlet 111, flows through the filter element 12, and then enters the inside of the center flow guide pipe 13 from the water inlet nozzle 15 on the side of the filter element head 14, and then flows through the center flow guide pipe 13 to the water outlet 112, and then flows out from the water outlet 112.

[0037] Specifically, one side of the filter cartridge 11 is provided with a drain port 113, the drain port 113 is sleeved with a drain cover 114, and the bottom of the filter cartridge 11 is fixedly connected with a plurality of supports 116 through a screw rod 115 and a nut.

[0038] In the embodiment, the drain cover 114 is connected with the drain port 113 in a threaded manner, the drain port 113 is used for discharging sewage when the filter element 12 is washed, the screw rod 115 is welded on the bottom of the filter cartridge 11, and the top of the support 116 is concave and arc-shaped and is matched with the shape of the filter cartridge 11.

[0039] In summary, the filter without disassembling the pipe to take out the filter element has multiple filter elements 12 arranged in a ring shape outside the center flow guide pipe 13, so that the water flow is uniformly distributed, the filtering area is greatly improved compared with the traditional vertical arrangement, the air gap 2 and the high-speed flow guide channel are combined, impurity accumulation is effectively reduced, the cleaning cycle is prolonged, the hinged clamp 17 is extruded and sealed in the sealing groove 18 through the inclined surface, the double-sealing ring structure is matched, the sealing performance is improved, unfiltered water leakage is avoided, the disassembly and assembly time is shortened, the structure is simple and compact, the economic benefits are met, and the application prospect is wide.
