[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. A fan filter unit is a self-powered air filtration device, usually used in clean rooms or dust-free workshops. It integrates a fan and a high-efficiency air filter, which can effectively remove particulate matter in the air and provide clean air for the working environment. The fan filter unit installation structure is a structure that fixes the fan filter unit in a specific position to ensure the normal operation of the fan. The existing fan filter unit installation structure is usually an integrated molding setting. When a certain part becomes loose, it is easy to cause the filter unit to fall as a whole, and the safety is low. Utility Model Content

[0003] In order to overcome the existing fan filter unit installation structure, it is usually an integrated setting. When a certain part is loose, it is easy to cause the filter unit to fall off as a whole, which has low safety.

[0005] Preferably, by modularly arranging the mounting structure into a first limiting component, a second limiting component, a first fixing component and a second fixing component, each component can fix the filter module individually or cooperate with each other to achieve multi-angle fixing to increase the stability of the filter module. When a component becomes loose, it will not cause the filter module to fall as a whole, thereby playing an anti-falling role. By arranging the first limiting component and the second limiting component, the filter module can be sleeved to prevent it from tipping over. By arranging the first fixing component and the second fixing component, the filter component can be installed and fixed at different positions respectively. By using the first limiting component, the second limiting component, the first fixing component and the third fixing component, different parts of the filter module can be installed and fixed at different positions of the wall respectively, so that the force can be dispersed, so that the force is not easy to concentrate, thereby preventing it from loosening and falling off. By arranging each component individually, even if a component becomes loose, it will not cause the filter module to fall, thereby playing an anti-falling role. Using multiple components for multi-angle fixing can achieve a better anti-falling effect.

[0006] Preferably, the first limiting assembly includes a placement rack, a first protective cover, a first connecting column, a first connecting block, a second connecting column, a second connecting block and a first mounting block. The inner corners of the placement rack are fitted with a first protective cover for protecting the filter module.

The middle part of the rear end of the first connecting column is rotatably connected to the second connecting column through the first connecting block. The second connecting column is rotatably connected to the first mounting block through the second connecting block. By arranging the first connecting block, the second connecting column and the second connecting block to be rotatably connected to each other, the angle and position of the first mounting block can be adjusted according to different situations, and it can also play a certain buffering role when subjected to external force.

By setting the first limiting component and the second limiting component to be detachably connected, the filter module is facilitated to be installed and removed.

[0008] Preferably, the second limiting assembly includes a limiting frame, a second protective cover and a third connecting column. The inner corners of the limiting frame are fitted with a second protective cover for protecting the filter module. The left and right ends of the limiting frame are symmetrically provided with two groups of third connecting columns for detachable connection with the first limiting assembly. The third connecting column is detachably connected to the first limiting assembly through a third mounting hole. A second limiting hole for detachable connection with the first limiting assembly is opened in the middle of the rear end of the limiting frame.

By arranging the third connecting block, the pull column and the fourth connecting block to be rotatably connected, the angle of the pull column can be adjusted according to different situations, and it can also play a certain buffering role in the event of a collision.

[0011] Preferably, a second mounting block for installing and fixing the fourth connecting block is provided at the rear end of the fourth connecting block, and fifth mounting holes for installing and fixing the second mounting block are provided around the four corners of the surface of the second mounting block.

[0012] Beneficial effects of the utility model:

[0013] 1. Compared with the traditional fan filter unit installation structure, which is usually an integrated setting, when a certain part is loose, it is easy to cause the filter unit to fall as a whole, and the safety is low. By modularizing the installation structure into a first limiting component, a second limiting component, a first fixing component and a second fixing component, each component can fix the filter module alone, and can also cooperate with each other to achieve multi-angle fixation to increase the stability of the filter module. When a certain component is loose, it will not cause the filter module to fall as a whole, thereby playing a role in preventing it from falling. By setting the first limiting component and the second limiting component, the filter module can be set in cooperation to prevent it from falling. By setting a placement rack, it can be used to place the filter module to limit its lower end. By setting the limiting component The rack can cover the upper end of the filter module, and the placement rack and the limiting rack can be connected and fixed together by setting the first connecting column and the third connecting column, so that the placement rack, the limiting rack, the first connecting column and the third connecting column can cooperate to limit the filter module so that it is blocked on the inside, thereby preventing it from tipping over and falling due to external forces such as collision. By respectively setting the first protective cover and the second protective cover on the inner sides of the placement rack and the limiting rack, the filter module can be protected to prevent it from being damaged by force. By setting a first mounting block at the rear end of the first connecting column and rotatably connected by the first connecting block, the second connecting column and the second connecting block, the first mounting block can be installed and fixed on the corresponding wall through the first mounting hole on the surface of the first mounting block, thereby the filter module can be hung on the wall.

[0014] By setting the first fixing component and the second fixing component, the filter component can be installed and fixed at different positions respectively. By setting the first fixing component, the main load-bearing and installation and fixing can be performed. By setting the support column, the first limiting component can be supported, so as to bear the main weight of the filter module. By setting the mounting plate with the fourth mounting hole at the rear end of the support column, the mounting plate can be fixed on the wall through the fourth mounting hole, and by setting the fixing column between the mounting plate and the support column, the reinforcement effect can be achieved. By setting the second fixing component at the left and right ends of the filter component, the filter component can be suspended and stressed. By setting the pulling column, it can be used for suspension and stress. By setting the second mounting block with the fifth mounting hole, the mounting block can be fixed on the wall. By installing and fixing different parts of the filter module at different positions of the wall by the first limiting component, the second limiting component, the first fixing component and the third fixing component, the force can be dispersed, so that the force is not easy to concentrate, so that it is not easy to loosen and fall off. Each component is set separately, even if a component is loose, it will not cause the filter module to fall off, so it can play a role in preventing falling off. Using multiple components for multi-angle fixing makes the anti-falling effect better. BRIEF DESCRIPTION OF THE DRAWINGS
