Description

Technical Field

[0001] The present application relates to the technical field of air filters, and in particular to a filter element for an air filter. Background Art

[0002] An air filter is an air purification device that captures dust from gas-solid two-phase flow through porous filter materials and purifies the gas. The filter element is the core component of the porous filter material, which can filter impurities in the fluid, protect the normal operation of the equipment and provide clean fluid.

[0003] Common filter elements mainly consist of a paper shell and a filter screen. The middle of the shell is hollowed out, and the filter screen is distributed in the middle of the shell. When installing, the shell is snapped into the opening of the air filter. However, since the surface of the shell is smooth, soft and easy to deform, the deformed shell cannot fit tightly with the opening of the air filter, resulting in a gap, causing air leakage and reducing the air filtration effect. Utility Model Content

[0004] In order to improve the problem of deformation of the filter element housing, causing air leakage and reducing the air filtering effect, the present application provides a filter element for an air filter.

One side of the outer shell is arranged as a mounting surface facing the air filter, and the other side is in contact with the external air. A sealing sponge is arranged around one end of the outer shell close to the mounting surface. The sealing sponge is used to abut against the inner wall of the opening of the air filter. A reinforcing component is also arranged on the outer shell. The reinforcing member is used to strengthen the strength of the outer shell.

[0007] By adopting the above technical solution, a sealing sponge is connected to one end close to the mounting surface, and when the mounting surface is connected to the opening of the air filter, the sealing sponge abuts against the inner wall of the opening of the air filter. If the outer shell is deformed, the gap formed after the deformation of the outer shell is effectively blocked under the action of the sealing sponge, thereby effectively preventing air leakage and ensuring the air filtration effect.

[0008] Optionally, the reinforcement member includes a reinforcing rib, which is located on the inner side of the shell and is distributed in plurality around the shell, and the plurality of reinforcing ribs sequentially connect two adjacent sides of the shell.

[0010] Optionally, the reinforcement member further includes ribs, which are distributed on the inner side surface of the shell, and two adjacent ribs on adjacent side surfaces are located at the top corners of the shell and vertically connected.

[0011] By adopting the above technical solution, the ribs are connected to the inner side of the shell, and the adjacent ribs are vertically connected to the top corners of the shell, thereby further reinforcing the shell, reducing deformation of the shell during installation, and providing a firm structure.

[0012] Optionally, an oblique support rod is connected between two adjacent ribs, and the oblique support rod is configured as a telescopic rod, and an adjusting member for adjusting the telescopic extension of the telescopic rod is provided on the oblique support rod.

[0013] By adopting the above technical solution, the diagonal support rod is arranged to abut the rib plate against the top corner of the shell by abutting, thereby making the structural strength of the shell corner high, effectively improving the stability of the shell, reducing deformation, ensuring the filtering effect, and the diagonal support rod is arranged as a telescopic rod, and the length of the diagonal support rod is adjusted by an adjusting piece, which is convenient for adjustment and installation.

[0014] Optionally, the diagonal support rod includes a first rod body and a second rod body, the first rod body is sleeved on the second rod body, and the adjustment member is provided on the first rod body and the second rod body to lock the first rod body on the second rod body.

[0015] By adopting the above technical solution, the first rod body and the second rod body are used as a set, so as to effectively adjust the length of the diagonal brace rod, facilitate the connection of the diagonal brace rod, and finally use the adjustment piece to lock the first rod body on the second rod body, thereby making the diagonal brace rod structure stable and having a good supporting effect.

[0016] Optionally, the adjusting member includes a locking bolt, and a plurality of screw holes are provided on the first rod body and the second rod body, one of the screw holes on the first rod body is aligned with one of the screw holes on the second rod body, and the locking screw is connected between the two screw holes.

[0017] By adopting the above technical solution, the provided locking bolt is connected to the screw hole, so that after the length of the diagonal brace is adjusted, the first rod body can be conveniently locked on the second rod body, and the structure is firm.

[0018] Optionally, a sticky adhesive strip is provided on the upper ring of the sealing sponge.

[0019] By adopting the above technical solution, the set adhesive strip can further fit with the outer shell at the opening of the air filter when the filter element is installed, thereby making the outer shell and the air filter firmly connected and reducing the possibility of falling off.

[0020] Optionally, the adjacent reinforcing ribs intersect on the shell.

[0021] By adopting the above technical solution, adjacent reinforcing ribs are made to intersect, thereby making the reinforcing rib structure stable, effectively improving the reinforcement effect of the outer shell, thereby reducing the deformation of the outer shell, and being very reliable.

[0022] In summary, this application includes the following beneficial technical effects:

[0023] 1. Through the sealing sponge, when the housing is installed at the opening of the air filter, the sealing sponge uses its own sealing properties to effectively reduce air leakage after a deformation gap appears between the housing and the air filter, thereby improving the air filtration effect;

[0024] 2. The adhesive strip is provided to further strengthen the connection between the housing and the air filter, reduce the possibility of the housing falling off, and ensure a reliable structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present application is further described in detail below in conjunction with the accompanying drawings.

[0029] The present application discloses a filter element for an air filter, referring to Figure 1 , comprising an outer shell 1 and a filter screen 2 connected to the inner shell 1. In this embodiment, the air passing through the filter screen 2 can filter out dust and impurities contained in the air. Therefore, one side of the outer shell 1 is set to be a mounting surface facing the air filter, and the other side is in contact with the external air. Later, in order to avoid deformation of the outer shell 1 during the installation process, which would cause a gap between the outer shell 1 and the air filter and cause air leakage, a sealing sponge 3 is provided at one end of the outer shell 1 close to the mounting surface. When the filter element is installed, the sealing sponge 3 can abut against the inner wall of the opening of the air filter, and then the sealing sponge 3 can be used to effectively seal the gap, thereby reducing air leakage and achieving a very reliable filtering effect.

[0030] When the sealing sponge 3 abuts against the inner wall of the air filter, in order to further reduce the slipping of the outer shell 1 during installation, an adhesive strip 8 is provided around the sealing sponge 3. The adhesive strip 8 utilizes its own viscosity and flexibility to make the outer shell 1 fit more tightly against the inner wall of the air filter and provide a firm structure.

[0031] In this embodiment, a reinforcement component is further provided on the shell 1, and the reinforcement part is used to strengthen the strength of the shell 1, including a reinforcing rib 4. The reinforcing rib 4 is located on the side opposite to the installation surface, and a plurality of reinforcing ribs 4 are distributed around the shell 1, and the plurality of reinforcing ribs 4 are sequentially connected to two adjacent sides of the shell 1, and the adjacent reinforcing ribs 4 are intersected on the shell 1; thereby, the reinforcing ribs 4 form a diamond shape on the shell 1, and the structure is firm. The adjacent sides of the shell 1 are connected by the reinforcing ribs 4, thereby effectively improving the strength of the shell 1, reducing the deformation of the shell 1, and the structure is reliable.

[0032] Reference Figure 2 In this embodiment, in order to further improve the strength of the shell 1, the reinforcement member also includes ribs 5, which are distributed on the inner side of the shell 1, and two adjacent ribs 5 on adjacent sides are vertically connected at the top corners of the shell 1, so that the two adjacent ribs 5 form a right angle, and the top corner of the shell 1 is effectively supported on the inner side of the shell 1. Therefore, when the shell 1 is installed, the deformation of the shell 1 is further reduced. In addition, a diagonal brace 6 is connected between two adjacent ribs 5. Through the support of the diagonal brace 6, the reinforcement of the shell 1 is further improved on the inner side of the shell 1, and the diagonal brace 6 is also set as a telescopic rod. The diagonal brace 6 is provided with an adjustment member for adjusting the telescopic rod, so that the diagonal brace 6 can be easily adjusted inside the shell 1, so that the use length and support strength of the diagonal brace 6 are adapted to the installation and use of the shell 1.

[0033] Reference Figure 2 In this embodiment, the diagonal brace rod 6 includes a first rod body 60 and a second rod body 61. By sleeved the first rod body 60 on the second rod body 61, the length between the first rod body 60 and the second rod body 61 can be adjusted by sliding, thereby effectively changing the supporting force of the diagonal brace rod 6; and the adjusting member is connected to the first rod body 60 and the second rod body 61 to lock the first rod body 60 on the second rod body 61, including a locking bolt 7, and the first rod body 60 and the second rod body 61 are provided with a plurality of screw holes; then one of the screw holes on the first rod body 60 is aligned with one of the screw holes on the second rod body 61, and finally the locking screw is connected between the two screw holes, thereby effectively locking the first rod body 60 on the second rod body 61, which is convenient to operate and has a reliable structure. What is needed is that in this embodiment, the installation of the rib plate 5 and the diagonal brace rod 6 is first adjusted in the shell 1 according to the size of the shell 1 and the installation requirements, and then the filter screen 2 is connected to the shell 1, and the filter screen 2 has at least two layers.

[0034] The implementation principle of a filter element for an air filter in the embodiment of the present application is as follows: by connecting a sealing sponge 3 at one end of the outer shell 1 close to the mounting surface, the gap between the outer shell 1 and the inner wall of the air filter is effectively sealed, air leakage is reduced, and the air filtering effect is ensured; reinforcing ribs 4 are connected on the side opposite to the mounting surface, and ribs 5 and diagonal support rods 6 are connected on the inner side of the outer shell 1, thereby effectively reinforcing the outer shell 1, reducing deformation of the outer shell 1, and ensuring a reliable structure.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
