Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically a combined filter element. Background Technology

[0002] Filter cartridges are commonly used devices in the filtration and purification industry to purify raw fluids. Currently, filter cartridges are mainly used in filtration industries such as oil filtration, air filtration, and water filtration. Filter cartridges separate solid particles from liquids or gases, or allow different substances to come into full contact, accelerate reaction time, and protect the normal operation of equipment or ensure air cleanliness. When fluid enters a filter cartridge containing a filter screen of a certain size, its impurities are blocked, while the clean fluid flows out through the filter cartridge. Liquid filter cartridges purify contaminated liquids to the state required for production and daily life, that is, to make the liquid reach a certain level of cleanliness.

[0003] Filter cartridges need to be replaced after a certain period of use to avoid affecting the filtration effect. However, existing filter cartridges are not easy to replace, which affects the user's subsequent use. Utility Model Content

[0021] (III) Beneficial Effects

[0022] Compared with the prior art, the present invention provides a combined filter element, which has the following beneficial effects:

[0023] This filter element is easy to replace. When the user needs to replace the filter element body, they lift the rotating ring, which moves the connecting rod upwards, disengaging the bottom of the connecting rod from the slot. Then, rotating the ring counterclockwise causes the connecting rod to slide to the right side of the groove. Lifting the connecting plate allows the filter element body and connecting plate to be removed from the housing. The connecting rod of the replacement filter element body is then inserted into the rightmost end of the groove, pushing the connecting rod upwards and stretching the spring. Rotating the ring clockwise at this point causes the connecting rod to slide clockwise to the top of the slot, where the spring's deformation pushes the connecting rod into the slot, thus securing the filter element body and connecting plate. This solves the problem of existing filter elements being inconvenient to replace after a certain period of use, thus affecting subsequent use. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] See Figure 1-4 A modular filter element includes a main component 1, which comprises: a housing 11, inside which a filter element body 12 is disposed; a replacement component 2 is disposed on the housing 11 and the filter element body 12, the replacement component 2 comprising: a connecting plate 21, fixedly connected to the top of the housing 11; a connecting rod 22, passing through and slidably connected to the connecting plate 21; a rotating ring 23, fixedly connected to the top of the connecting rod 22; a spring 24, fixedly connected between the rotating ring 23 and the connecting plate 21, the spring 24 being sleeved on the outside of the connecting rod 22; a sliding groove 25, formed at the top of the housing 11; and a slot 26, formed inside the housing 11, the sliding groove 25 and the slot 26 being connected through each other. Multiple sets of the connecting rod 22, the spring 24, the sliding groove 25, and the slot 26 are symmetrically arranged, with at least two sets. The bottom diameter of the connecting rod 22 is larger than the top diameter.

[0034] When the user needs to replace the filter element body 12, the user lifts the rotating ring 23, which moves the connecting rod 22 upward. The bottom of the connecting rod 22 disengages from the slot 26. Then, the user rotates the rotating ring 23 counterclockwise, which causes the connecting plate 21 and the connecting rod 22 to rotate counterclockwise. The connecting rod 22 slides from the left to the right side of the slide groove 25. When the connecting rod 22 slides to the edge of the slide groove 25, the user lifts the connecting plate 21, and the filter element body 12, along with the connecting plate 21, can be removed from the outer casing 11, making it convenient for the user to clean or replace the filter element body 12. Then, the connecting rod 22 on the replacement filter element body 12 is inserted into the rightmost end of the slide groove 25. When the bottom of the connecting plate 21 contacts the top of the outer shell 11, the connecting rod 22 is pushed upward, causing the rotating ring 23 to move upward and the spring 24 to be stretched. At this time, the user rotates the rotating ring 23 clockwise, and the rotating ring 23 causes the connecting rod 22 to slide in the slide groove 25. When the connecting rod 22 slides clockwise to the top of the slot 26, the elastic force generated by the deformation of the spring 24 pushes the connecting rod 22 into the slot 26, thus completing the fixation of the filter element body 12 and the connecting plate 21. The multiple sets of connecting rods 22, springs 24, slide grooves 25 and slots 26 provide multiple limiting points between the outer shell 11 and the connecting plate 21, and the connecting rods 22 are all controlled by the rotating ring 23, which increases the stability after the outer shell 11 and the connecting plate 21 are connected, and also makes it easy to disconnect the connecting rods 22 from the outer shell 11 at the same time. The shape of the groove 25 is adapted to the connecting rod 22. Since the bottom diameter of the connecting rod 22 is larger than the top diameter, the connecting rod 22 cannot detach from the groove 25 when it slides inside the groove 25, thereby increasing the firmness of the connection between the outer shell 11 and the filter element body 12.

[0035] Example 2

[0036] An auxiliary function has been added based on Embodiment 1.

[0037] See Figure 1-4 A telescopic shell 241 is fixedly connected between the rotating ring 23 and the connecting plate 21, and the telescopic shell 241 is sleeved on the outside of the spring 24. The rotating ring 23 is provided with anti-slip texture 231 on its outer side. Handles 27 are symmetrically and fixedly connected to the outer side wall of the connecting plate 21.

[0038] When the spring 24 extends or retracts, the telescopic shell 241 outside the spring 24 extends or retracts along with the spring 24. The telescopic shell 241 shields the spring 24, preventing the user's hand from coming into contact with the extending spring 24 and causing injury when installing the filter element body 12. The anti-slip texture 231 on the outside of the rotating ring 23 increases the friction between the user's hand and the rotating ring 23 when rotating it, thus facilitating the operation of the rotating ring 23. The handle 27 on the outside of the connecting plate 21 facilitates the user's movement of the connecting plate 21, thereby facilitating the installation and removal of the filter element body 12.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
