Description

Technical Field

[0001] The utility model relates to the technical field of filtering, and more specifically to a filter element with a replaceable filter element. Background Art

[0002] A filter element is a component of a device used to purify water, air or other fluids, usually made of various materials such as fiber, activated carbon, ceramic, etc. They are designed to remove impurities, odors, microorganisms, etc. from water or air to improve water or air quality. Commonly used ones include activated carbon filter elements, ceramic filter elements, PP cotton filter elements, and composite filter elements, etc. Filters with replaceable filter elements are usually used in water purifiers, air purifiers and other equipment. Their main function is to filter impurities and pollutants from water or air.

[0003] The filter element is an important component of the air filter element. However, the existing air filter element mainly includes a filter element and a filter element frame for fixing the filter element. After the air filter element has been used for a period of time, its filter element is affected by dust and other pollutant particles, and the filtering performance is reduced, and it needs to be replaced regularly. Since the filter element and the filter element frame for fixing the filter element are designed as an integral whole, at this time, it is necessary to replace them as a whole. However, the overall replacement of the filter element is relatively wasteful and has low economic efficiency. For this reason, we propose a filter element with a replaceable filter element to solve the above problem. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a filter element with a replaceable filter element to solve the problems existing in the above-mentioned background technology.

[0005] The filter element is a filter element having a plurality of independently controlled filters, each of which has a plurality of independently controlled filters, and a plurality of independently controlled filters are provided on the filter element.

[0006] Preferably, the retaining ring, the spring and the moving plate are all arranged inside the moving groove, and the spring is arranged between the moving plate and the retaining ring.

[0007] Preferably, slots are symmetrically provided on both sides of the outer walls of the upper cover plate and the lower cover plate, and the slots match the insertion rods.

[0008] Preferably, the upper fixing plate and the lower fixing plate are of the same size and shape, the upper cover plate and the lower cover plate are of the same size and shape, and the diameter of the upper fixing plate and the lower fixing plate is larger than the diameter of the upper cover plate and the lower cover plate.

[0009] Preferably, the support rod is symmetrically provided with limit sliding grooves at the upper and lower ends of a side away from the filter element, and the inner wall of the limit sliding groove is slidably connected to a limit fixed sliding block.

[0010] Preferably, the position-limiting fixed slider and the position-limiting sliding groove form a sliding connection structure, and a slot matching the handle is provided on a side of the position-limiting fixed slider close to the handle.

[0011] Technical effects and advantages of the utility model:

[0012] 1. The utility model is provided with a fixing mechanism. When the device is used, when the filter element needs to be replaced, the handle is first pulled outward to make the insertion rod move outward and disengage from the slot. The above operation is repeated to disengage the insertion rods fixedly connected to both sides of the upper cover plate and the lower cover plate from the slot in turn. Then the filter element can be easily removed and a new filter element can be replaced between the upper fixed plate and the lower fixed plate. At this time, under the resetting action of the rebound force of the spring, the movable plate is pushed to move along the movable groove toward the filter element, thereby pushing the insertion rod to be inserted into the slot, and the replacement and installation of the filter element can be completed. The operation is convenient, the maintenance is convenient, and the installation and disassembly efficiency of the filter element can be improved. There is no need to replace the entire filter element. Only the filter element needs to be removed and replaced, which is beneficial to saving the use cost and improving the practicality of the device.

[0013] 2. The utility model is provided with a limit sliding groove and a limit fixing slider. When the device is used, the limit fixing slider is moved toward the pull handle by sliding the limit fixing slider so that the groove provided on one side of the limit fixing slider clamps the pull handle, thereby completing the limit fixation of the pull handle, thereby facilitating the limiting of the insertion rod and facilitating the subsequent replacement and maintenance of the filter element.

[0021] In the embodiment of the present application, during actual use, when the filter element needs to be replaced, the handle 61 is first pulled outward, and the handle 61 drives the pull rod 62 to move outward, thereby driving the movable plate 65 to move outward along the movable groove 9 to squeeze the spring 64. At this time, the spring 64 is in a compressed state, so that the insertion rod 66 moves outward and disengages from the slot 8. Subsequently, the sliding limit fixing slider 11 is moved toward the handle 61, so that the slot opened on one side of the limit fixing slider 11 clamps the handle 61, thereby completing the limit fixation of the handle 61, and repeating the above operation to fix the upper cover 2 and the upper cover 2 in turn. The insertion rods 66 on both sides of the lower cover plate 3 are disengaged from the slots 8, and then the filter element 1 can be easily removed, and a new filter element 1 can be replaced between the upper fixed plate 4 and the lower fixed plate 5. Thereafter, it is only necessary to pull the limit fixing slider 11 in sequence so that the limit fixing slider 11 slides along the limit sliding groove 10 to disengage from the limit fixation of the pull handle 61. At this time, under the resetting action of the rebound force of the spring 64, the moving plate 65 will be pushed along the moving groove 9 toward the filter element 1, thereby pushing the insertion rod 66 to be inserted into the slot 8, and the replacement and installation of the filter element 1 can be completed. The operation is convenient, maintenance is convenient, and it is convenient to improve the installation and disassembly efficiency of the filter element 1.

[0022] Furthermore, the retaining ring 63, the spring 64 and the movable plate 65 are all arranged inside the movable groove 9, and the spring 64 is arranged between the movable plate 65 and the retaining ring 63. When in use, the retaining ring 63 is arranged to facilitate the telescopic movement of the spring 64.

[0023] Furthermore, slots 8 are symmetrically provided on both sides of the outer walls of the upper cover plate 2 and the lower cover plate 3 , and the slots 8 match the insertion rods 66 . When in use, the insertion rods 66 match the slots 8 , so that the filter element 1 is fixed more firmly and reliably.

When in use, the diameters of the upper fixing plate 4 and the lower fixing plate 5 are set slightly larger than the diameters of the upper cover plate 2 and the lower cover plate 3, so that the filter element 1 can be easily installed between the upper fixing plate 4 and the lower fixing plate 5.

[0025] Furthermore, limiting grooves 10 are symmetrically provided at the upper and lower ends of the side of the support rod 7 away from the filter element 1, and the inner wall of the limiting groove 10 is slidably connected to a limiting fixed slider 11. The limiting fixed slider 11 and the limiting groove 10 constitute a sliding connection structure. A slot matching the pull handle 61 is provided on the side of the limiting fixed slider 11 close to the pull handle 61. When in use, the limiting fixed slider 11 is moved toward the pull handle 61 by sliding the limiting fixed slider 11 so that the pull handle 61 is clamped by the slot on one side of the limiting fixed slider 11, thereby completing the limiting fixation of the pull handle 61.

[0026] Working principle of the utility model: in actual use, when the filter element needs to be replaced, first pull the handle 61 outward, the handle 61 drives the pull rod 62 to move outward, thereby driving the movable plate 65 to move outward along the movable groove 9 to squeeze the spring 64. At this time, the spring 64 is in a compressed state, so that the insertion rod 66 moves outward and disengages from the slot 8. Subsequently, the sliding limit fixing slider 11 moves toward the handle 61, so that the slot opened on one side of the limit fixing slider 11 clamps the handle 61, thereby completing the limit fixation of the handle 61, repeating the above operation, and fixing it on the upper cover plate in turn. 2 and the insertion rods 66 on both sides of the lower cover plate 3 are disengaged from the slots 8, and then the filter element 1 can be easily removed, and a new filter element 1 can be re-placed between the upper fixing plate 4 and the lower fixing plate 5, and then it is only necessary to pull the limit fixing slider 11 in sequence to make the limit fixing slider 11 slide along the limit sliding groove 10 to disengage the limit fixation of the pull handle 61. At this time, under the resetting action of the rebound force of the spring 64, the moving plate 65 will be pushed to move along the moving groove 9 toward the filter element 1, thereby pushing the insertion rod 66 to be inserted into the slot 8, and the replacement and installation of the filter element 1 can be completed.
