While traditional air filters can improve air quality to some extent, they often suffer from being bulky and inconvenient to replace. Especially for spaces with limited space, such as homes and offices, traditional air filters are often insufficient. Utility Model Content

[0003] The purpose of this invention is to address the above-mentioned shortcomings by providing a foldable air filter that solves the technical problems of bulky filter elements and inconvenient filter element replacement in existing technologies.

[0004] The purpose of this utility model is achieved by the following method: a foldable air filter, including a housing, a control module and a motor, wherein the control module is assembled on the right side of the housing, the motor is assembled in the inner cavity of the housing, and the output end of the motor is connected to a fan blade, and the inner cavity of the housing is equipped with a filter element mechanism.

[0005] The filter element mechanism includes a filter cartridge, with limiting plates connected to both the upper and lower ends of the filter cartridge. The bottom limiting plate of the filter cartridge has evenly spaced slots on its outer side, and the top limiting plate of the filter cartridge has evenly spaced locking rods on its outer side. T-shaped plates are connected to the left and right sides of the outer side of the limiting plates. A slotted block is sleeved on the outer side of the T-shaped plate. A sliding groove is formed at the bottom of the slotted block, and the slotted block is connected to the inner cavity of the housing.

[0006] Furthermore, a sealing plate is embedded on the right side of the housing, and a handle is connected to the right side of the sealing plate. An anti-slip sleeve is fitted on the outside of the handle. The sealing plate can release the housing from its seal, thereby facilitating the removal and replacement of the filter element by the staff.

[0007] Furthermore, air intake plates are embedded on the top and outside of the housing, and air holes are evenly distributed on the outside of the air intake plates. The air intake plates allow external airflow to enter the inner cavity of the housing and be purified before being discharged.

[0008] Furthermore, the inner cavity of the housing is equipped with a support plate, which is located directly above the filter element mechanism and can support and fix the filter element mechanism.

[0009] Furthermore, the bottom of the slotted block is provided with a horizontal groove, which is adapted to the T-shaped plate, and the horizontal groove facilitates the insertion of the T-shaped plate into the interior of the slotted block for assembly.

[0010] Furthermore, the motor is externally fitted with a bracket, which is connected to the inner cavity of the housing, and the bracket can support and fix the motor.

[0011] The beneficial effects of this utility model are as follows: by adding a filter cartridge, a limiting plate, a locking rod, and a locking groove, the filter cartridge and the limiting plate can be folded quickly, thereby greatly reducing the overall volume of the device and reducing the space required for the filter element mechanism during storage. At the same time, by adding a T-shaped plate, a slotted block, a sliding groove, and a transverse groove, the limiting plate can be quickly engaged in the inner cavity of the housing, thereby greatly improving the assembly speed of the filter element mechanism.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] In this embodiment, refer to Figure 1 and Figure 2 The specific implementation of the foldable air filter includes a housing 1, a control module 2 and a motor 6. The control module 2 is assembled on the right side of the housing 1, the motor 6 is assembled in the inner cavity of the housing 1, and the output end of the motor 6 is connected to a fan blade 61. The inner cavity of the housing 1 is equipped with a filter element mechanism 5.

[0019] Please see Figure 3 and Figure 4 The housing 1, control module 2, and motor 6 are common air filtration devices in the prior art. The housing 1 is used to support the control module 2 and motor 6. The control module 2 can control the operation of motor 6 and display its working status.

[0020] The filter element mechanism 5 includes a filter cartridge 51. Both the upper and lower ends of the filter cartridge 51 are connected to a limiting plate 52. The bottom limiting plate 52 of the filter cartridge 51 has evenly spaced slots 54. The top limiting plate 52 of the filter cartridge 51 has evenly spaced locking rods 53. T-shaped plates 55 are connected to the left and right sides of the limiting plate 52. A slotted block 56 is sleeved on the outside of the T-shaped plate 55. A sliding groove 57 is opened at the bottom of the slotted block 56. The slotted block 56 is connected to the inner cavity of the housing 1.

[0021] The filter cartridge 51 can support the limiting plate 52. The filter cartridge 51 is made of polypropylene and can filter the air. The clamping rod 53 can be inserted into the inner cavity of the clamping groove 54 to fix the limiting plate 52. The T-shaped plate 55 can be inserted into the slotted block 56 through the transverse groove 58 and rotate in the inner cavity of the slide groove 57.

[0022] A sealing plate 4 is embedded on the right side of the housing 1. A handle 41 is connected to the right side of the sealing plate 4, and an anti-slip sleeve is fitted on the outside of the handle 41. The sealing plate 4 can release the seal of the housing 1, so that the staff can take out and replace the filter element mechanism 5. An air inlet plate 3 is embedded on the top and outside of the housing 1. Air holes are evenly distributed on the outside of the air inlet plate 3. The air inlet plate 3 can allow the external airflow to enter the inner cavity of the housing 1 and be purified and discharged.

[0023] The inner cavity of the housing 1 is equipped with a support plate 7, which is located directly above the filter element mechanism 5. The support plate 7 can support and fix the filter element mechanism 5. The bottom of the slotted block 56 is provided with a horizontal groove 58, which is adapted to the T-shaped plate 55. The horizontal groove 58 facilitates the insertion of the T-shaped plate 55 into the interior of the slotted block 56 for assembly. The motor 6 is equipped with a bracket on the outside, which is connected to the inner cavity of the housing 1. The bracket can support and fix the motor 6.

[0024] When the filter element mechanism 5 needs to be replaced, open the sealing plate 4 from the outside of the air intake plate 3, take out the filter element mechanism 5, and press the two limiting plates 52 in a square shape so that the locking rod 53 is inserted into the inside of the locking groove 54, thereby folding the filter element mechanism 5 and taking out the new filter element mechanism 5. Pull the limiting plates 52 to a position away from each other so that the locking rod 53 and the locking groove 54 are separated. Then insert the T-shaped plates 55 at both ends into the inner cavity of the transverse groove 58 so that the T-shaped plates 55 rotate 90 degrees inside the sliding groove 57, thereby locking the filter element mechanism 5 into the outside of the slotted block 56 in the inner cavity of the housing 1.

[0025] By adding the filter cartridge 51, limiting plate 52, locking rod 53 and locking groove 54, the filter cartridge 51 and limiting plate 52 can be quickly folded, thereby greatly reducing the overall volume of the device and reducing the space required for storage of the filter element mechanism 5. At the same time, by adding the T-shaped plate 55, slotted block 56, sliding groove 57 and transverse groove 58, the limiting plate 52 can be quickly locked into the inner cavity of the housing 1, thereby greatly improving the assembly speed of the filter element mechanism 5.
