Detailed Description

Referring to fig. 1, the present application provides a technical solution: the utility model provides an inside has filter of multistage layer-stepping filter screen, includes cartridge filter 1, and cartridge filter 1's inner wall slidable mounting has layering filter screen 2, and layering filter screen 2's surface is equipped with assembly structure 3, and cartridge filter 1's inner wall is equipped with push-and-pull structure 4.

The specific arrangement and function of the mounting structure 3 and the push-pull structure 4 will be described in detail below.

Referring to fig. 1 and 2 and fig. 4 and 5, in the present embodiment: the assembly structure 3 comprises three support rods 33, the three support rods 33 are fixedly connected with the inner wall of the layered filter screen 2, the surfaces of the three support rods 33 are rotatably provided with a rotary drum 34, the side wall of the rotary drum 34 is fixedly connected with a fan plate 32, and the inner side of the filter cartridge 1 is provided with a clamping groove 31. After the inner wall of the filter cartridge 1 is sleeved with the layered filter screen 2, after the fan plate 32 moves to the position on the same horizontal plane with the clamping groove 31, the fan plate 32 rotates to the position on the inner wall of the clamping groove 31, and the fan plate 32 is clamped on the inner wall of the clamping groove 31, so that the assembly between the filter cartridge 1 and the layered filter screen 2 is realized. A handle 35 is slidably inserted into the interior of the rotating cylinder 34, and circular blocks 36 are fixedly connected to both ends of the handle 35. By lifting and twisting the handle 35, the handle 35 rotates the drum 34 on the side wall of the rod 33.

The handle 35 is sleeved with a first spring 37 on the outer peripheral surface thereof, and both ends of the first spring 37 are fixedly connected with the circular block 36 and the rotary drum 34 respectively. The provision of the first spring 37 serves to drive the circular block 36 to move away from the drum 34. The inner wall of the handle 35 is fixedly connected with a rectangular strip 38, and the end side of the support rod 33 is provided with a limit groove 39. The rectangular strip 38 on the handle 35 is clamped on the inner wall of the limiting groove 39, and the fixing work of the turnover back fan plate 32 can be realized.

Referring to fig. 3 and 6, specifically, the push-pull structure 4 includes three positioning blocks 42, the three positioning blocks 42 are all fixedly connected with the inner wall of the layered filter screen 2, slide rods 43 are all slidably connected inside the three positioning blocks 42, and push plates 41 are fixedly connected to the end surfaces of the three slide rods 43. The impurity that push pedal 41 will be close to two port positions of cartridge filter 1 layering filter screen 2 surfaces is cleared up to the mediation effect that is close to two port positions of cartridge filter 1 in the cartridge filter 1 use has been guaranteed. The surface of the sliding rod 43 is sleeved with a second spring 44, and two ends of the second spring 44 are respectively fixedly connected with the positioning block 42 and the push plate 41. The provision of the second spring 44 serves to reset the drive push plate 41.

The side wall of the push plate 41 is glued with a rubber ring 45, and the rubber ring 45 is positioned between the layered filter screen 2 and the push plate 41. The rubber ring 45 is arranged to improve the tightness of the contact between the push plate 41 and the layered filter screen 2.

The working principle is as follows: when needs are installed the layering filter screen 2 in cartridge filter 1, with the inner wall of layering filter screen 2 cover income cartridge filter 1 after, after fan board 32 removed to the position that is in same horizontal plane with draw-in groove 31, hand handle 35, lift and twist handle 35, handle 35 can drive rotary drum 34 rotatory at the lateral wall of branch 33, rotate the position to draw-in groove 31 inner wall when fan board 32, fan board 32 card is at the inner wall of draw-in groove 31, thereby realized the assembly to between cartridge filter 1 and the layering filter screen 2, through setting up assembly structure 3, made things convenient for the rapid Assembly to between filter screen and the layering filter screen 2, thereby made things convenient for the dismantlement clearance of user to layering filter screen 2 in cartridge filter 1.

When the handle 35 is loosened, the rectangular strip 38 on the handle 35 is clamped on the inner wall of the limiting groove 39 under the elastic force action of the first spring 37 between the circular block 36 and the rotary drum 34, so that the fixed work of the turnover back fan plate 32 can be realized, and the stability of the fan plate 32 clamped on the inner wall of the clamping groove 31 is improved.

In-process at rivers flow, rivers can impact push pedal 41 and slide to the one side that is close to locating piece 42, and flow from the both sides of tee bend structure filter tube, when closing the valve, push pedal 41 can receive elasticity effect promotion push pedal 41 and reset at 2 inner walls of layered filter screen on locating piece 42, push pedal 41 can clear up the impurity that is close to two port position layered filter screen 2 surfaces of cartridge filter 1, thereby guaranteed the mediation effect that is close to two port positions of cartridge filter 1 in the cartridge filter 1 use, setting up of rubber circle 45 has improved the compactness that pastes between push pedal 41 and the layered filter screen 2, and then improved the clearance effect to 2 inner wall impurity of layered filter screen, through setting up push-and-pull structure 4, the mediation effect that is close to two port positions of cartridge filter 1 in the cartridge filter 1 use has been guaranteed.
