Description

Technical Field

[0001] This utility model relates to the field of air purification technology, specifically to an indoor ventilation and air purification device. Background Technology

[0002] Indoor ventilation and air purification equipment is a comprehensive environmental improvement device that integrates air circulation and replacement with pollutant filtration and purification functions. It can effectively solve problems such as poor indoor air circulation and pollutant accumulation, creating a healthy and comfortable breathing environment for users.

[0003] The air purification function of ventilation equipment mainly relies on activated carbon filter cotton. After a period of use, the filter cotton needs to be replaced in time. However, the process of disassembling the filter screen is very complicated. Workers need to repeatedly operate the bolts at a high place indoors to remove the filter screen and replace the filter cotton. The whole process is not only time-consuming and laborious, but also significantly increases the risk of injury to personnel because it requires climbing ladders for long-term high-altitude work. Utility Model Content

[0004] The purpose of this invention is to provide an indoor ventilation and air purification device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an indoor ventilation and air purification device, comprising a frame, a connection port fixedly connected to one side of the frame, a bracket fixedly connected inside the frame, a motor fixedly installed on the bracket, a plurality of fan blades fixedly connected to the output end of the motor, an abutment frame fixedly connected inside the frame, a filter screen slidably connected inside the frame at a position corresponding to the abutment frame, and filter cotton movably placed inside the filter screen;

[0006] Symmetrically arranged rotating rods are rotatably connected to the outer wall of the frame. Each rotating rod has a pressing rod fixedly connected to one end. The outer wall of the filter screen is provided with a quick-release mechanism, which includes two support blocks. Each support block has a support rod fixedly connected to it. Each support rod has a telescopic rod slidably connected to it. Each telescopic rod has a limit block fixedly connected to one end. Each limit block has a limit groove. Each limit block has a spring fixedly connected to it at the position corresponding to the telescopic rod.

[0007] Preferably, both ends of the extrusion rod are arc-shaped, and one end of the extrusion rod is engaged in the corresponding limiting groove.

[0008] Preferably, the support blocks are symmetrically and fixedly connected to the outer wall of the filter screen.

[0009] Preferably, one end of each telescopic rod slides through the hollow position of the corresponding spring, and one end of each spring is fixedly connected to the corresponding support rod.

[0010] Preferably, the limiting grooves are all arc-shaped.

[0011] Compared with existing technologies, the advantages of this invention are: the quick-release mechanism allows workers to remove the filter screen simply by rotating two limit rods, eliminating the need for repeated operations at heights indoors. This significantly shortens the filter replacement time and reduces the possibility of injury to workers, making it extremely convenient to operate. Furthermore, the quick-release mechanism is simple in composition, low in operating costs, and highly practical. Attached Figure Description

[0017] 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.

[0018] Please see Figure 1-4 The present invention provides the following technical solution:

[0019] Example 1: An indoor ventilation and air purification device includes a frame 1, a connection port 2 fixedly connected to one side of the frame 1, a bracket 3 fixedly connected inside the frame 1, a motor 4 fixedly installed on the bracket 3, a plurality of fan blades 5 fixedly connected to the output end of the motor 4, an abutment frame 6 fixedly connected inside the frame 1, a filter screen 7 slidably connected inside the frame 1 at a position corresponding to the abutment frame 6, and filter cotton 8 movably placed inside the filter screen 7.

[0020] In use, the frame 1 can be installed high on the ceiling or wall, the connection port 2 can be connected to the air supply duct, the motor 4 can be started, the motor 4 will drive the fan blade 5 to rotate, the rotation of the fan blade 5 will draw indoor air into the frame 1, the drawn air will be filtered and purified by the filter screen 7 and the filter cotton 8, and then the air that enters the frame 1 can be discharged through the air supply duct connected to the room through the connection port 2, thus completing the ventilation.

[0021] Example 2: The technical solution of this example, which differs from that of Example 1, includes: symmetrically arranged rotating rods 9 are rotatably connected to the outer wall of the frame 1, and a pressing rod 10 is fixedly connected to one end of each rotating rod 9; a quick-release mechanism 11 is provided on the outer wall of the filter screen 7; the quick-release mechanism 11 includes two support blocks 111, a support rod 112 is fixedly connected to each support block 111, a telescopic rod 113 is slidably connected to each support rod 112, a limit block 114 is fixedly connected to one end of each telescopic rod 113, a limit groove 115 is provided on each limit block 114, and a spring 116 is fixedly connected to each limit block 114 at the position corresponding to the telescopic rod 113;

[0022] Both ends of the extrusion rod 10 are arc-shaped. One end of the extrusion rod 10 is engaged in the corresponding limiting groove 115. The support block 111 is symmetrically fixedly connected to the outer wall of the filter screen 7. One end of the telescopic rod 113 slides through the hollow position of the corresponding spring 116. One end of the spring 116 is fixedly connected to the corresponding support rod 112. The limiting groove 115 is arc-shaped.

[0023] When using the filter screen 7 to replace the filter cotton 8, simply rotate the squeezing rod 10. The squeezing rod 10 will rotate around the rotating rod 9 as the center. The rotation of the squeezing rod 10 will squeeze the inner wall of the limiting groove 115. The pressure on the wall of the limiting groove 115 will act on the limiting block 114. At this time, the limiting block 114 will move away from the squeezing rod 10. The movement of the limiting block 114 will drive the telescopic rod 113 to retract into the support rod 112. At the same time, the limiting block 114 will also squeeze and retract the spring 116 through the support rod 112. When the limiting block 114 has moved a certain distance, the squeezing rod 10 will completely separate from the limiting groove 115. The operation of the other squeezing rod 10 is the same. When both squeezing rods 10 are in the corresponding limiting grooves 115... When separating, the filter screen 7 loses the joint fixation of the squeezing rod 10 and the limiting block 114, allowing the filter screen 7 to be removed from the frame 1. Then, the filter cotton 8 inside the filter screen 7 can be directly removed and replaced. After that, the filter screen 7 is returned to its original position. Then, the squeezing rod 10 is rotated towards the limiting block 114. The arc-shaped part of the squeezing rod 10 will squeeze the corner of the limiting block 114, causing the limiting block 114 to move away from the squeezing rod 10. When the squeezing rod 10 rotates to the corresponding limiting groove 115 position, the spring 116 will drive the limiting block 114 to reset, so that the limiting groove 115 on the limiting block 114 is reconnected with the squeezing rod 10, completing the fixation of the filter screen 7. The operation is extremely convenient and can significantly shorten the time required for disassembling and assembling the filter screen 7.

[0024] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
