Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air purification devices, in particular to a hanging air purifier. BACKGROUND

[0002] Air purifiers are used in the fields of home, medical treatment and industry. In the field of home, single-machine household air purifiers are the mainstream products in the market. The main function is to remove particulate matter in the air, including allergens and indoor PM2.5. In addition, the air purifier can also solve the problem of volatile organic compounds in indoor, underground space and car caused by decoration or other reasons.

[0003] The patent document with the application number 201811588774.5 discloses a hanging air purification device, which comprises a device body and a hanging bracket. The device body is located in the hanging bracket. The hanging bracket comprises a bottom support, a top compression assembly and an upper baffle. The bottom support comprises a first support assembly and a second support assembly. The top compression assembly is located above the device body and is connected with the upper baffle.

[0004] For the related technology in the above, the inventors believe that the air purifier generally processes the inhaled air through a filter such as a sieve plate. With the extension of the use time, more dust adheres to the sieve plate, which affects the working efficiency of the air purification device. Therefore, the sieve plate often needs to be taken out from the air purification device for cleaning or replacement. However, the designed hanging air purification device fixes the air purification device through a containment structure, which is not convenient for taking out the sieve plate in the air purification device for cleaning. SUMMARY

[0005] In order to facilitate the taking out of the filter in the air purification device for cleaning, the present application provides a hanging air purifier, which adopts the following technical scheme:

[0006] A hanging air purifier comprises a purifier body, an annular ring, a stress disc, a hanging strip, a preloading plate, an installation barrel and a pressing assembly.

[0007] The purifier body is connected with the annular ring, and the annular ring is connected with the stress disc.

[0008] The number of the hanging strips is at least two. The at least two hanging strips are evenly distributed along the circumference of the stress disc, and the hanging strips are connected in parallel with the stress disc. The hanging strips are connected with locking blocks.

[0009] The installation barrel is connected with the preloading plate. A gap slot is formed in the bottom wall of the installation barrel for the stress disc and the hanging strip to pass through. A plurality of locking holes are formed in the circumference of the bottom wall of the installation barrel for the locking blocks to be inserted.

[0010] The clamping component is installed on the pre-installed plate to make the hanging strip abut against the inner side of the bottom wall of the installation barrel.

[0011] By adopting the above technical solution, the annular ring is first connected to the purifier body, and then the annular ring is connected to the force-bearing disc. Simultaneously, the pre-assembled plate and installation bucket are pre-assembled and installed on the ceiling or wall. Force is applied to the purifier body, causing the force-bearing disc and hanging strip to align with the clearance groove. Force is continued to be applied until the force-bearing disc and hanging strip pass through the clearance groove and enter the inner cavity of the installation bucket. The purifier body is rotated until the angle is appropriate, and then the force application to the purifier body is stopped. Force is applied to the force-bearing disc using the clamping component, causing the force-bearing disc to move until the locking block on the hanging strip inserts into the locking hole. The purifier body is then suspended and installed. The designed suspended air purifier, through the annular ring, force-bearing disc, and hanging strip... The combination of the pre-installed plate and the mounting bucket allows for suspension without enclosing the purifier body, thus not obstructing the removal of the screen and facilitating the removal of the filter components from the air purifier for cleaning. The clamping component reduces the possibility of the locking block coming out of the locking hole due to vibration of the purifier body. Furthermore, during suspension installation, the two parts are installed separately, requiring only the adjustment of the purifier body's position to complete the installation. This eliminates the need for workers to hold the purifier body for extended periods, effectively reducing their workload. The designed suspension structure can be effectively concealed between the purifier body and the wall, resulting in a more aesthetically pleasing appearance without interfering with the operation of the purifier body.

[0012] Optionally, the clamping assembly includes a guide rod, a force-applying disc, and a compression spring;

[0013] The guide rod is coaxial with the mounting bucket and connected to the pre-installed plate. The guide rod passes through the force-applying plate and the force-receiving disc in sequence, and the guide rod is rotatably connected to the force-receiving disc.

[0014] The compression spring is sleeved on the guide rod, and the compression spring is located between the pre-installed plate and the force-applying plate.

[0015] By adopting the above technical solution, force is applied to the purifier body. The purifier body drives the force-receiving disc to move through the annular ring. The force-receiving disc drives the hanging strip to move and simultaneously applies force to the force-applying disc. The force-applying disc moves towards the pre-installation plate along the guide rod axis, causing the compression spring to compress. Then, the purifier body rotates around the guide rod as the rotation axis until the purifier body is in the appropriate position. The compression spring returns to its original position and drives the force-applying disc to move. The force-applying disc applies force to the force-receiving disc, causing the locking block on the hanging strip to insert into the locking hole, completing the suspension installation of the purifier body. The designed clamping component, through the guide rod, facilitates the provision of a rotation center axis for the purifier body and also provides auxiliary support when installed on the wall, preventing the possibility of tilting of the purifier body and the force-applying disc. The force-applying disc and the compression spring work together to facilitate the application of force to the force-receiving disc, providing reliability for the suspension of the purifier body.

[0016] Optionally, the force-applying plate is circumferentially connected with multiple anti-tilt rods, the anti-tilt rods are staggered from the hanging strips, and the anti-tilt rods are slidably connected to the bottom wall of the mounting bucket.

[0017] By adopting the above technical solution, when installed on the wall, since there is a gap between the center of gravity of the purifier body and the pre-installed plate, the force-bearing disc mainly bears the lateral overturning force applied by the purifier body. At this time, the interaction force applied by the force-bearing disc to the force-applying disc is also a lateral overturning force. However, since the force-applying disc has a double anti-lateral overturning function with guide rods and anti-tilt rods, and is also assisted by compression springs, the reliability of wall installation can be improved. The designed anti-tilt rod can further prevent the force-applying disc from tilting, thus improving the installation reliability of the purifier body when installed on the wall.

[0018] Optionally, an anti-tilting ring is coaxially connected to the side of the force-applying disc away from the force-receiving disc, and the outer periphery of the anti-tilting ring is slidably connected to the inner periphery of the mounting barrel.

One end of the anti-detachment plate is rotatably connected to the stepped groove. When the anti-detachment plate is in contact with the working surface of the stepped groove, the side of the anti-detachment plate away from the working surface of the stepped groove is coplanar with the plane of the inner side of the bottom wall of the mounting barrel.

[0021] By adopting the technical scheme, force is applied to the purifier body, the purifier body drives the stress disc to move through the annular ring, the stress disc moves towards the anti-drop plate when passing through the accommodation slot, the anti-drop plate is attached to the second working surface of the step groove from the first working surface of the step groove, at this time the stress disc is separated from the anti-drop plate, the anti-drop plate is reset under the action of its own gravity and is attached to the first working surface of the step groove, then the compression spring is reset to make the stress disc abut against the stress disc, at this time the stress disc abuts against the anti-drop plate away from the side of the pre-assembly plate and the side of the anti-drop plate away from the first working surface of the step groove, the anti-drop plate provides auxiliary support for the stress disc, and can prevent the stress disc from being accidentally taken out of the installation barrel.

[0022] Optionally, a plurality of heat dissipation holes are formed in the stress disc, and the annular ring cavity is in communication with the outside through the heat dissipation holes.

[0023] By adopting the technical scheme, the heat dissipation holes are designed to facilitate the installation of the annular ring and the purifier body.

[0024] Optionally, the purifier body comprises a back plate, a filter, a central partition plate, a motor, a gas sending fan wheel, a front air inlet plate, an air inlet cover plate and a side air outlet plate.
