[0023] 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.

[0024] Example: Figures 1-5As shown, the air filter device includes a filter bag 1 and a filter housing 2 applied to the air filter device. The filter housing 2 applied to the air filter device includes an upper shell 201 and a lower shell 202. The upper shell 201 and the lower shell 202 are arranged vertically to enclose and form a filter cavity 203. The upper shell 201 is provided with an air inlet 204 communicating with the filter cavity 203. The filter cavity 203 is provided with a plurality of support bars 205 spaced apart around the lower shell 202. The plurality of support bars 205 and the upper shell 201 enclose and form a filter cavity 203. The accommodating space 206 is formed. The support bar 205 has a radial support portion 207 and an axial stop portion 208. The radial support portion 207 extends inward from the peripheral wall of the filter chamber 203 and is spaced apart from the upper shell 201. The axial stop portion 208 is provided on the radial support portion 207 and extends from bottom to top, at least abutting against the upper shell 201. The axial stop portion 208 is located next to one end of the radial support portion 207 adjacent to the cavity wall of the filter chamber 203. The filter bag 1 is accommodated in the accommodating space 206. The lower side of the filter bag 1 abuts against the radial support portion 207, and the peripheral side of the filter bag 1 abuts against the axial stop portion 208. This embodiment provides an air filtration device to solve the problem of low purification efficiency in existing air purification devices where the filter material is housed inside the outer shell and its bottom is attached to the lower shell. Air entering the outer shell from the air inlet can only contact the upper side of the filter material. The solution is achieved by arranging several support bars 205 within the filter chamber 203. These support bars 205 are spaced apart circumferentially around the lower shell 202 and enclose the upper shell 201 to form a housing space 206. Each support bar 205 has a radial support portion 207 extending inward from the peripheral wall of the filter chamber 203 and spaced apart from the upper shell 201. The filter bag 1 is housed within the housing space 206 and its lower side abuts against the radial support portion 207. This ensures that the filter bag 1 is exposed to the air except for the area in contact with the support bars 205. The large contact area between the filter bag 1 and the air effectively promotes the release of purified substances within the filter bag 1, resulting in more comprehensive and efficient purification. Meanwhile, since the support bar 205 also has an axial stop 208 located on one end of the radial support portion 207 adjacent to the wall of the filter chamber 203 and extending from bottom to top to at least abut against the upper shell 201, the filter bag 1 and the filter shell 2 are assembled stably, preventing the filter bag 1 from slipping or tipping over during the operation or movement of the air filter device, and ensuring that the filter bag 1 is always in the preset working position.

[0025] In this embodiment of the invention, the support bar 205 further includes an inner support portion 209 disposed on the radial support portion 207. The inner support portion 209 and the axial stop portion 208 are disposed opposite to each other on the radial support portion 207, with the inner support portion 209 located inward and the axial stop portion 208 located outward. The inner support portion 209 and the radial support portion 207 are disposed at an angle, and the inner support portion 209 is L-shaped or V-shaped. This arrangement, by configuring the L-shaped or V-shaped inner support portion 209 on the radial support portion 207, provides the support bar 205 with a good supporting effect.

[0026] In this embodiment of the invention, the support bar 205 is integrally formed on the upper side of the lower shell 202. The radial support portion 207 extends inward from the peripheral wall of the filter cavity 203 along the upper side of the lower shell 202. The axial stop portion 208 extends upward from the upper side of the lower shell 202. The inner support portion 209 extends upward from the upper side of the lower shell 202 and is flush with the radial support portion 207. By configuring the support bar 205 integrally formed with the lower shell 202, with the radial support portion 207 extending inward from the peripheral wall of the filter cavity 203 along the upper side of the lower shell 202, the axial stop portion 208 extending upward from the upper side of the lower shell 202, and the inner support portion 209 extending upward from the upper side of the lower shell 202 and flush with the radial support portion 207, the support bar 205 possesses good structural strength and support effect.

[0027] In this embodiment of the invention, at least the portion of the upper shell 201 facing the accommodating space 206 extends downwards. Specifically, the downwardly recessed portion of the upper shell 201 abuts against the filter bag 1. This arrangement, by configuring the upper shell 201 such that at least the portion facing the accommodating space 206 extends downwards, ensures stable assembly of the filter bag 1.

[0028] In this embodiment of the invention, the upper shell 201 is provided with a plurality of air inlet groups 210, each consisting of a plurality of air inlets 204 formed on the upper shell 201. The plurality of air inlets 204 in the same group are spaced apart circumferentially on the upper shell 201, and the plurality of air inlet groups 210 are spaced apart radially on the upper shell 201. This arrangement, by configuring a plurality of air inlet groups 210 on the upper shell 201, with the plurality of air inlets 204 in the same group spaced apart circumferentially on the upper shell 201, and the plurality of air inlet groups 210 spaced apart radially on the upper shell 201, ensures that the upper shell 201 has a good air intake effect and excellent purification effect.

[0029] In this embodiment of the present invention, in any two adjacent air inlet groups 210, each air inlet 204 of the outer air inlet group 210 is defined as an outer air inlet 211, and each air inlet 204 of the inner air inlet group 210 is defined as an inner air inlet 212. The aperture of the outer air inlet 211 is larger than that of the inner air inlet 212. Since the filter bag 1 is located in the center, and the aperture of the outer air inlet 211 is larger than that of the inner air inlet 212, the air inlet 204 closer to the filter bag 1 has a finer aperture, and the air inlet 204 farther away from the filter bag 1 has a larger aperture. This avoids excessive release of purified substances from the filter bag 1 and extends the service life of the filter bag 1.

[0030] In this embodiment of the invention, the external air vent 211 and the internal air vent 212 are staggered in the circumferential direction of the upper shell 201. This arrangement, by staggering the external air vent 211 and the internal air vent 212 in the circumferential direction of the upper shell 201, avoids excessive release of purified substances from the filter pack 1 and extends the service life of the filter pack 1.

[0031] In this embodiment of the invention, the upper shell 201 has a sealing portion 213 and a venting portion 214. The sealing portion 213 faces the accommodating space 206, and the venting portion 214 is arranged around the sealing portion 213 and has a plurality of air inlet groups 210. This arrangement, by configuring the upper shell 201 to face the sealing portion 213 of the accommodating space 206 and the venting portion 214 arranged around the sealing portion 213 and having a plurality of air inlet groups 210, provides the upper shell 201 with good air intake performance. Simultaneously, it avoids excessive release of purified substances from the filter bag 1, extending the service life of the filter bag 1.

[0032] In this embodiment of the invention, the upper shell 201 and the lower shell 202 are detachably and fixedly connected. The upper shell 201 is provided with a locking block (not shown in the figure), and the lower shell 202 is provided with a locking groove (not shown in the figure) that engages with the locking block. The locking groove is an L-shaped groove. The upper shell 201 is fixed to the lower shell 202 by screwing. By configuring the upper shell 201 and the lower shell 202 into a detachable and fixed connection, the filter bag 1 is easily disassembled, installed, and replaced.
