Description

Technical Field

[0001] The utility model relates to the technical field of suction tip filter cores, in particular to a suction tip filter core that can prevent falling off. Background Art

[0002] A filter element is a component used in water filtration equipment. It is usually composed of multiple layers of filter materials and can effectively remove impurities, chlorine, odor and other pollutants in water. It is used in a wide range of scenarios, including food, medical, chemical, etc. The filter element is connected to the pipe or equipment through the suction head.

[0003] However, in the prior art, the traditional filter element has no anti-falloff mechanism during use. Therefore, under the impact of water pressure, the filter element is easily caused to fall off during use, resulting in the inability to filter the water flow. In addition, during use, because the traditional filter element has no anti-accidental touch mechanism, the staff may accidentally touch the filter element's fixing mechanism when touching the filter element, causing the fixing mechanism to release the filter element, thereby affecting subsequent work.

The outer wall of the sliding column 23 is slidably connected to the inner wall of the sliding ring 35. The fixing mechanism 5 includes a fixed cylinder 56, the inner wall of the fixed cylinder 56 is fixedly connected to the soft claw 53, the inner wall of the fixed cylinder 56 is fixedly connected to the limiting block 54, the inner wall of the fixed cylinder 56 is fixedly connected to the outer wall of the resistance rod 34, the inner wall of the fixed cylinder 56 is fixedly connected to the end of the tension spring 33 away from the slider 32, the outer wall of the slider 32 is slidably connected to the inner wall of the fixed cylinder 56, and the inner wall of the fixed cylinder 56 is provided with a groove corresponding to the slider 32.

[0037] Working principle:

[0038] When in use, first install the filter element mechanism 4 into the suction head body 1, slide the anti-slip mechanism 3 upwards so that the anti-slip mechanism 3 slides upwards and out of the fixing mechanism 5. After the anti-slip mechanism 3 slides out, place the filter element mechanism 4 on the fixing mechanism 5, and then rotate the filter element mechanism 4 so that the fixing block 43 in the filter element mechanism 4 slides into the fixing hook 31 in the anti-slip mechanism 3. Then release the force on the anti-slip mechanism 3 so that the anti-slip mechanism 3 slides back into the fixing mechanism 5. During the sliding process of the anti-slip mechanism 3, the filter element mechanism 4 is brought into the fixing mechanism 5 by the fixing hook 31. When the filter element mechanism 4 slides into the fixing mechanism 5, the installation of the filter element mechanism 4 is completed. Then use the locking mechanism 2 to lock the anti-slip mechanism 3, thereby further fixing the filter element mechanism 4, and then the filtering work can be carried out.

[0039] When installing the filter element mechanism 4, it is necessary to align the fixing block 43 on the fixing ring 42 with the limiting groove 51. After the fixing block 43 slides into the limiting groove 51, the sliding ring 35 is slid upward. The sliding ring 35 drives the slider 32 to slide synchronously through the connecting column 36. The positioning groove 52 in the fixing cylinder 56 is used to limit the sliding position of the connecting column 36. During the sliding process of the slider 32, the tension spring 33 under the slider 32 is stretched. A fixing hook 31 is fixed on the slider 32. Therefore, during the upward sliding process of the slider 32, the fixing hook 31 is extended out of the fixing cylinder 56. After the fixing hook 31 is extended, the fixing ring 42 is rotated to make the fixing block 43 slide The slider 32 is inserted between the two fixing hooks 31, and then the force on the slip ring 35 is released. When the slip ring 35 is released, the stretched tension spring 33 pulls the slider 32 downward under the action of elasticity, so that the slider 32 is reset. In the process of resetting the slider 32, the fixing block 43 is synchronously driven to slide downward, so that the fixing block 43 slides into the fixing cylinder 56, and a resistance rod 34 is fixed between the slider 32 and the fixing cylinder 56. Under the resistance of the resistance rod 34, the slider 32 reduces the displacement caused by shaking. During the sliding process, the slider 32 drives the filter shell 41 on the fixing ring 42 to slide into the suction head body 1. At this time, the filter element mechanism 4 is installed.

[0040] After the filter element mechanism 4 is installed, the anti-slip mechanism 3 needs to be locked to further fix the filter element mechanism 4. At this time, the locking ring 21 is rotated so that the locking ring 21 drives the sliding post 23 to rotate synchronously. The top of the locking ring 21 is connected to the sliding ring 35 through the sliding post 22, thereby assisting the sliding of the locking ring 21. The sliding post 23 is located in the slide groove 55 in the fixed cylinder 56. Therefore, during the sliding process of the sliding post 23, the sliding post 23 first contacts the soft claw 53, causing the soft claw 53 to deform. Under the continuous rotation of the sliding post 23, the sliding post 23 is turned into the slot in the slide groove 55. After the sliding post 23 slides into the slot, the sliding post 23 does not contact the soft claw 53, so under the elastic action of the soft claw 53, the soft claw 53 is reset. When the sliding post 23 is located in the slot, because the limiting block 54 is fixed in the fixing cylinder 56, the sliding post 23 cannot slide from the slot into the sliding groove 55 without external force due to the obstruction of the limiting block 54. When disassembling the filter element mechanism 4, it is only necessary to rotate the locking ring 21 with force to make the sliding post 23 slide over the limiting block 54, and then slide the locking ring 21 upward to make the sliding post 23 slide over the soft claw 53, and the fixing of the sliding post 23 can be released.
