[0020] The term "embodiment" as used herein means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] This utility model provides an air filter.

[0023] Reference Figure 1-2 The air filter includes a housing 1, a purification module 2, and a plug-in connector 3. Specifically, the housing 1 serves as the main support structure of the air filter. The interior of the housing 1 forms a purification channel 11 for air circulation. The purification channel 11 extends in a straight line. The housing 1 has multiple mounting and disassembly windows 12, which are distributed sequentially along the extension direction of the purification channel 11. Each mounting and disassembly window 12 is connected to the purification channel 11, and all the mounting and disassembly windows 12 are located on the same outer wall of the housing 1.

[0024] The purification module 2 is installed into the purification channel 11 through the installation / removal window 12, with one purification module 2 corresponding to one installation / removal window 12. Specifically, the purification module 2 is the core component for achieving air purification. Generally, the purification module 2 in an air purifier includes filter media, filter media support components, and a fixed frame. The filter media, which filters the air, is bonded to the fixed frame through a sealing adhesive method. For example, hot melt adhesive is used to bond and seal the connection between the filter media and the fixed frame. During operation, polluted air passes through the filter media, which is generally composed of various fibers and cotton pulp and has moderate strength. If the airflow entering the purification channel 11 is strong, it will damage the filter media. Therefore, a support frame is laid on the surface of the filter media to increase its strength. This support frame is generally made of wire mesh.

[0025] Correspondingly, depending on the level of air filtration required, filter media are categorized into pre-filters, medium-efficiency filters, and high-efficiency filters, as well as functional filters that can filter specific pollutants. Pre-filters generally intercept large particles, medium-efficiency filters further filter finer particles, while high-efficiency filters can filter microparticles such as PM2.5, secondhand smoke particles, and bacteria. Functional filters can target specific pollutants based on their properties; for example, filters with added activated carbon can adsorb odors from harmful gases.

[0026] The plug-in connector 3 connects the outer shell 1 and the purification module 2 to enable the assembly and disassembly of the purification module 2 and the outer shell 1. The plug-in connector 3 is released by applying a force parallel to the center line of the assembly / disassembly window 12. For example, pressing or pulling the purification module 2 can disconnect the connection between the purification module 2 and the outer shell 1.

[0027] In summary, by providing multiple mounting and disassembly windows 12 on the outer casing 1, the required purification modules 2 can be freely arranged and placed according to the different types of air to be filtered. Furthermore, a plug-in connector 3 is provided to allow the purification modules 2 to be conveniently inserted or removed from the mounting and disassembly windows 12 on the outer casing 1, thereby achieving the effect of convenient mounting and disassembly of the purification modules 2.

[0028] As mentioned above, in order to realize the plug-in connection function of the purification module 2, the plug-in connector 3 can adopt a magnetic structure. Specifically, the plug-in connector 3 includes a magnet and an adsorption plate. The magnet is set on the inner wall of the purification channel 11, and the magnet is located in a position opposite to the installation and removal window 12. The adsorption plate is set on the outer surface of the purification module 2, and the adsorption plate is magnetically connected to the magnet.

[0029] When the purification module 2 is inserted into the purification channel 11 through the installation and removal window 12, the adsorption sheet moves with the purification module 2 to the position corresponding to the magnet, and the two are stably connected by magnetic adsorption. When disassembling, simply pull the purification module 2 outward along the center line of the installation and removal window 12. When the pulling force is greater than the magnetic attraction force, the adsorption sheet separates from the magnet, and the purification module 2 can be easily removed.

[0030] Reference Figure 2-3 Another way to implement the plug-in connector 3 is, for example, by using a snap-fit ​​connection. Considering that the snap-fit ​​connection requires a certain amount of installation space, the inner wall of the purification channel 11 needs to be provided with a corresponding module slot 111. The module slot 111 is located on the inner wall of the purification channel 11 on the side away from the installation and removal window 12. The shape of the module slot 111 is consistent with the shape of the installation and removal window 12, and is used to allow the end of the purification module 2 away from the installation and removal window 12 to be inserted, so as to prevent the purification module 2 from having a gap with the inner wall of the purification channel 11.

[0031] Specifically, this plug-in connector 3 includes a latch 31 and a buckle 32. The latch 31 is a press-locking latch 31, which is fixed to the bottom of the module slot 111, with the latch claws facing the opening of the module slot 111. The buckle 32 protrudes from the end of the purification module 2 near the module slot 111. During installation, the purification module 2 is inserted into the module slot 111, and the buckle 32 pushes the latch claws of the latch 31 to close until the buckle 32 enters the locked position, with the latch claws enclosing the buckle 32. During disassembly, pressing the purification module 2 into the purification channel 11 triggers the latch 31 to unlock, and then pulling it outwards removes the purification module 2.

[0032] Reference Figure 2 Based on the aforementioned snap-fit ​​connector, to enhance the sealing of the purification channel 11 and prevent unpurified air from flowing through gaps, a splicing sealing strip 112 is further provided on the inner wall of the purification channel 11. The splicing sealing strip 112 is located at the edge of the slot of the module slot 111, that is, the splicing sealing strip 112 is not inside the module slot 111, but on the inner wall of the purification channel 11, but relatively close to the edge of the slot of the module slot 111. The splicing sealing strip 112 is made of elastic materials such as silicone rubber. Two splicing sealing strips 112 are provided for each module slot 111. The two splicing sealing strips 112 are located on opposite sides of a purification module 2, with the side of the splicing sealing strips 112 that is close to each other abutting against the purification module 2.

[0033] When the purification module 2 is inserted into the module slot 111, the splicing sealing strip 112 is squeezed and undergoes elastic deformation, effectively sealing the gap between the purification module 2 and the module slot 111, thus improving the purification efficiency.

[0034] Meanwhile, there will be gaps where the installation and disassembly window 12 contacts the purification module 2. In order to ensure the sealing of the installation and disassembly window 12, a through-seal strip 113 is provided on the inner wall of the purification channel 11. The through-seal strip 113 is located in the installation and disassembly window 12. The through-seal strip 113 is also made of elastic material. Each installation and disassembly window 12 is provided with two through-seal strips 113. The two through-seal strips 113 are located on opposite sides of a purification module 2. The side of the two through-seal strips 113 that is close to each other abuts against the purification module 2.

[0035] When the purification module 2 passes through the installation and removal window 12, the sealing strip 113 is squeezed and tightly adheres to the outer surface of the purification module 2, blocking the gap between the purification module 2 and the installation and removal window 12, forming a double sealing guarantee.

[0036] Reference Figure 4 Since the plug-in connector 3 is a snap-fit ​​connection, in order to prevent the purification module 2 from moving towards the bottom of the module slot 111 due to vibration or other unexpected situations, which would cause the connection between the purification module 2 and the outer shell 1 to loosen or even cause the purification module 2 to detach from the outer shell 1, an anti-detachment protection component 4 is provided on the part of the purification module 2 exposed outside the purification channel 11 and the installation and removal window 12. The function of the anti-detachment protection component 4 is to restrict the purification module 2 from moving towards the bottom of the module slot 111, so that the purification module 2 will not be connected to the outer shell 1.

[0037] Reference Figure 4 Specifically, the anti-detachment protective component 4 includes a locking ring 41, a locking block 42, and a locking spring 43. The locking ring 41 is fixedly connected to the purification module 2, and the locking ring 41 is located on the part of the purification module 2 outside the purification channel 11 and the installation and removal window 12. The locking block 42 is slidably connected to the outer shell 1, and the sliding direction is perpendicular to the center line of the installation and removal window 12. One end of the locking block 42 passes through the inner side of the locking ring 41. One end of the locking spring 43 is connected to the locking block 42, and the other end is fixed to the outer shell 1. In its natural state, the locking spring 43 keeps the locking block 42 in the state of passing through the locking ring 41.

[0038] During disassembly, simply pull the locking block 42 to overcome the spring force of the locking spring 43 and disengage from the locking ring 41 to release the limit.

[0039] In addition, a dust grille 5 is installed at the air inlet of the purification channel 11 to filter larger debris such as paper scraps, hair, and dust during air filtration, preventing the purification module 2 from being quickly clogged. The dust grille 5 is made of metal or hard plastic with a mesh structure and is detachably connected to the outer casing 1 by bolts. The connection position can be at the end face of the purification channel 11, so that when the grille is not needed or when the grille surface is heavily soiled, the bolts can be quickly unscrewed to remove the dust grille 5 for subsequent cleaning or replacement.

[0040] In summary, the air filter provided by this utility model enables the quick assembly and disassembly of the purification module 2 through the assembly and disassembly window 12 provided on the housing 1 and the plug-in connector 3 provided on the housing 1 and the purification module 2; the sealing of the purification channel 11 is maintained by the splicing sealing strip 112 and the through sealing strip 113; and the connection reliability is enhanced by the anti-detachment protective component 4.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
