Technical Field

[0001] The utility model relates to the technical field of air supply and exhaust filtering, in particular to an air filtering structure of an air supply and exhaust system. Background Art

[0002] The supply and exhaust air system is an important ventilation facility in a building. It is mainly used to remove exhaust gas, odor and heat from the room to ensure indoor air quality. Its working principle is to use a fan to draw out indoor air through the air duct, while allowing fresh air to enter through the vents. The exhaust system can not only improve the living and working environment, but also effectively prevent the accumulation of moisture and harmful substances.

[0003] When maintaining and replacing filters in traditional filtration systems, multiple components usually need to be disassembled, and professional maintenance personnel are required to perform the disassembly, maintenance or replacement. As a result, the disassembly and assembly of the filter structure in the air duct is not only cumbersome and time-consuming, but also prone to operational errors or component damage, increasing the operating burden of the system and affecting the normal operation and maintenance efficiency of the equipment.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 2 An embodiment of the present utility model provides an air filtering structure of an air supply and exhaust system, comprising: an air duct 1 and a U-shaped partition 8.

[0020] In this embodiment, Figure 1-Figure 4As shown, the U-shaped partition 8 is installed on the inner wall of the air duct 1, and two slide grooves 7 are symmetrically provided on the inner wall of the U-shaped partition 8. A movable frame 6 is slidably installed on the slide groove 7. The bottom of the air duct 1 is symmetrically provided with a linear groove 15. The bottom of the movable frame 6 passes through the linear groove 15 and is fixedly connected to a horizontal plate 2. Two bearings 14 are symmetrically embedded on the horizontal plate 2. The inner ring of the bearing 14 is fixedly connected to a movable ring 3. The top of the movable ring 3 is fixedly connected to an L-shaped plate 12, and the length of the L-shaped plate 12 is greater than the width of the linear groove 15. A filter screen 9 is detachably installed inside the movable frame 6.

[0021] Furthermore, both ends of the air duct 1 are provided with supply and exhaust holes 5, and air can enter the interior of the air duct 1 through the supply and exhaust holes 5. When the air in the air duct 1 flows, it can enter the filter 9 through the guidance of the U-shaped partition 8, and the filter 9 is used to filter the air.

[0022] When the filter 9 needs to be maintained or replaced, the two movable rings 3 are rotated to move one end of the L-shaped plate 12 to the same vertical plane and parallel to the linear groove 15, and then the movable ring 3 is pulled downward, thereby pulling the movable frame 6 and the filter 9 out of the linear groove 15 at the bottom of the air duct 1, exposing the filter 9 to the outside, and canceling the stable state of the filter 9 inside the movable frame 6 by rotating the blocks 10 on the front and rear surfaces of the movable frame 6, thereby quickly completing the disassembly operation of the filter structure and facilitating further maintenance or replacement of the filter 9.

[0023] Further, refer to Figure 3 The bottom inner wall of the chute 7 is fixedly connected with a damping block 13. When the top of the movable frame 6 moves to the bottom inner wall of the chute 7, the damping block 13 can prevent the top of the movable frame 6 from directly colliding with the bottom inner wall of the chute 7.

[0024] Among them, such as Figure 2 As shown, four blocks 10 are symmetrically mounted on the front and rear surfaces of the movable frame 6 through a pin shaft 11. When the block 10 rotates horizontally, it fits against the outer wall of the filter screen 9. When the filter screen 9 is installed in the movable frame 6, the block 10 on the front and rear surfaces of the movable frame 6 can be used to rotate and fit against the front and rear outer walls of the filter screen 9, so that the filter screen 9 is stabilized inside the movable frame 6.

[0025] like Figure 1 As shown, baffles 4 are installed at the bottom of the air duct 1 and on both sides close to the horizontal plate 2. The baffles 4 can shield and protect the horizontal plate 2 and both sides of the movable ring 3.

[0026] According to the above technical solution, the working steps of this solution are summarized and sorted out: when in use, the air flow in the air duct 1 can enter the filter 9 through the guidance of the U-shaped partition 8, and the filter 9 is used to filter the air.

[0027] When the filter 9 needs to be maintained or replaced, the two movable rings 3 are rotated to move one end of the L-shaped plate 12 to the same vertical plane and parallel to the linear groove 15, and then the movable ring 3 is pulled downward, thereby pulling the movable frame 6 and the filter 9 out of the linear groove 15 at the bottom of the air duct 1, exposing the filter 9 to the outside, and canceling the stable state of the filter 9 inside the movable frame 6 by rotating the blocks 10 on the front and rear surfaces of the movable frame 6, thereby quickly completing the disassembly operation of the filter structure and facilitating further maintenance or replacement of the filter 9.

[0028] When the filter screen 9 is installed inside the air duct 1, the filter screen 9 is placed inside the movable frame 6, the stopper 10 is rotated to fit the surface of the filter screen 9, and the movable frame 6 is pushed into the air duct 1. The movable ring 3 is rotated in the opposite direction so that one end of the L-shaped plate 12 passes through the top opening of the linear groove 15 and fits against the bottom inner wall of the air duct 1, completing the quick installation operation of the filter structure.

[0029] Any portion not described in the present invention is the same as the prior art or can be implemented using the prior art. Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
