Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to an air filter with anti-detachment function. Background Technology

[0002] Air filters are air filtration devices, generally used in cleanrooms, clean factories, laboratories, and clean rooms, or for dust prevention in electronic, mechanical, and communication equipment. They come in various models, including pre-filters, medium-efficiency filters, high-efficiency filters, and sub-high-efficiency filters, each with different standards and performance levels.

[0003] In related technologies, air filters require regular cleaning of the internal filter element to prevent dust accumulation from affecting the filter's performance. During filter disassembly, the clips used to secure the upper housing lack protective measures and may detach from the lower housing during outward rotation. These clips are easily lost during cleaning and can affect the efficiency of filter assembly. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an air filter with an anti-detachment function. This prevents the clips used for fixing from falling off during disassembly, thereby avoiding the loss of clips and improving the efficiency of subsequent filter assembly.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An air filter with anti-detachment function includes a lower housing, an upper housing on the upper side of the lower housing, a first fixing ear on the right side of the upper housing, a slot at the upper end of the first fixing ear, a second fixing ear on the right side of the lower housing, a buckle on the right side of the second fixing ear, the lower end of the buckle being installed inside the second fixing ear, an elbow on the upper end of the buckle, a hook groove for engaging with the slot at the lower side of the elbow on the upper end of the buckle, an installation groove on the lower side of the right end of the second fixing ear, a rotating rod passing through the installation groove at the lower end of the second fixing ear, and an anti-detachment plate rotatably connected to the outside of the rotating rod.

[0007] Furthermore, a hook bar is provided inside the lower end of the second fixing ear, and a hook for engaging with the hook bar is provided at the lower end of the buckle.

[0008] Furthermore, the top of the buckle is provided with a lever for pulling the buckle.

[0009] Furthermore, a connecting block is provided on the left side of the lower housing, and a through hole is provided in the middle of the connecting block.

[0010] Furthermore, a connecting pin is provided on the left side of the upper housing, and the end of the connecting pin is inserted into the interior of the connecting block.

[0011] Furthermore, a sealing gasket for sealing is provided between the lower housing and the upper housing.

[0012] Furthermore, the lower housing is provided with fixing handles at both the front and rear ends for fixing the filter.

[0013] This utility model has the following beneficial effects:

[0014] In this invention, when cleaning the filter, a paddle pulls the buckle, causing the top bend and hook groove to separate from the slot and rotate outward. As the buckle rotates outward, the anti-detachment plate has no obstruction and rotates outward. During the rotation, due to its elasticity, the buckle's overall bending range increases, thereby bringing the top of the anti-detachment plate closer to the hook groove. Ultimately, the top of the anti-detachment plate engages with the hook groove, securing the top of the buckle and preventing it from falling off. This avoids loss during cleaning and improves the efficiency of filter assembly. Attached Figure Description

[0020] 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.

[0021] Reference Figures 1-3 An embodiment of this utility model provides an air filter with an anti-detachment function, including a lower housing 1, an upper housing 2 on the upper side of the lower housing 1, a first fixing ear 3 on the right side of the upper housing 2, a slot 4 at the upper end of the first fixing ear 3, a second fixing ear 7 on the right side of the lower housing 1, a buckle 8 on the right side of the second fixing ear 7, the lower end of the buckle 8 being installed inside the second fixing ear 7, an elbow 14 at the upper end of the buckle 8, a hook groove 15 for engaging with the slot 4 at the lower side of the elbow 14 at the upper end of the buckle 8, a hook bar 12 inside the lower end of the second fixing ear 7, a hook 13 for engaging with the hook bar 12 at the lower end of the buckle 8, a lever 16 for pulling the buckle 8 at the top of the buckle 8, an installation groove 9 at the lower right end of the second fixing ear 7, a rotating rod 10 passing through the lower end of the second fixing ear 7 at the position of the installation groove 9, and an anti-detachment piece 11 rotatably connected to the outside of the rotating rod 10.

[0022] The buckle 8 has a certain degree of elasticity. When the buckle 8 is not constrained, it is in a bent state. When fixing the filter, the hook 13 at the lower end of the buckle 8 hooks the hook bar 12, and the elbow 14 at the upper end of the buckle 8 cooperates with the slot 4. The elbow 14 hooks the edge of the slot 4, thereby fixing the lower housing 1. At this time, the anti-detachment plate 11 is blocked by the buckle 8 and cannot rotate. When the filter is cleaned and disassembled, the lever 16 at the top of the buckle 8 is pulled to separate the elbow 14 from the slot 4 and drive it to rotate outward. After the elbow 14 is separated from the slot 4, the lever is released. 16. As the buckle 8 continues to rotate outward, it is no longer restrained by external force and its bending range increases due to its own elasticity. At the same time, as the buckle 8 rotates outward, the anti-detachment plate 11 is no longer obstructed and rotates outward under the action of gravity. During the rotation, the top of the anti-detachment plate 11 gradually approaches the hook groove 15 and finally stops inside the hook groove 15. At this time, the hook 13 at the lower end of the buckle 8 hooks the hook bar 12, and the buckle 8 can no longer rotate, thus avoiding the problem of falling off and preventing the buckle 8 from being lost during the cleaning process. At the same time, it can reduce the difficulty of assembling the filter and improve the assembly efficiency.

[0023] Reference Figure 1 - Figure 3 A connecting block 5 is provided on the left side of the lower housing 1, and a through hole is provided in the middle of the connecting block 5. A connecting pin 6 is provided on the left side of the upper housing 2, and the end of the connecting pin 6 is inserted into the interior of the connecting block 5. A sealing gasket 17 for sealing is provided between the lower housing 1 and the upper housing 2. Fixing handles 18 for fixing the filter are provided at both the front and rear ends of the lower housing 1.

[0024] When assembling the filter housing, the sealing gasket 17 is installed on the lower housing 1, and then the connecting pin 6 on the upper housing 2 is inserted into the connecting block 5. Then the upper housing 2 is placed on the upper side of the lower housing 1 so that the first fixing ear 3 and the second fixing ear 7 are engaged. Finally, the buckle 8 is moved so that the elbow 14 at the upper end of the buckle 8 is engaged with the slot 4, thus completing the assembly between the filter housings.

[0025] Working principle: When cleaning the filter element, the lever 16 is pulled outward to separate the elbow 14 from the slot 4 and cause the buckle 8 to rotate outward. After the elbow 14 separates from the slot 4, the buckle 8 retracts due to its own elasticity, increasing the curvature of the buckle 8. When the buckle 8 rotates outward, the anti-detachment plate 11 has no obstruction and rotates outward by gravity. During the rotation, the top of the buckle 8 gradually approaches the hook groove 15 and finally engages with the hook groove 15. At this time, the hook 13 at the lower end of the buckle 8 hooks the hook bar 12, and the hook groove 15 at the upper end engages with the elbow 14, preventing the buckle 8 from continuing to rotate and thus preventing the buckle 8 from falling off.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
