Description

Technical Field

[0001] The invention relates to the technical field of air sterilization, and in particular to a fumigation fan used for air sterilization. Background Art

[0002] Fumigation sterilization is a common method of disinfecting and sterilizing the air in a space. It is widely used in the medical, biochemical, pharmaceutical and other industries. As the name suggests, fumigation sterilization is to spray high-temperature disinfectant gas (or atomized liquid) into the space to be disinfected. These disinfectant gases kill and disinfect bacteria and other substances in the air. In order to make the disinfectant gas spread more widely, it is generally used in conjunction with a fan. The fan-assisted gas injection can increase the diffusion range and sterilization effect of the disinfectant gas.

[0003] However, as far as the existing fumigation fans used for air sterilization are concerned, the angle of their fan blades is fixed and cannot be adjusted. When the airflow size needs to be adjusted, it can only be achieved by changing the motor speed. When the motor speed is constant, the airflow size cannot be adjusted. The airflow size cannot be mechanically adjusted, which leads to high limitations in the use of fumigation fans. In addition, to achieve the adjustment of the fan blade angle, it is necessary to simultaneously meet the conditions that all fan blades can be adjusted synchronously and the rotating parts can maintain dynamic balance during rotation, so as to ensure the normal use of the fumigation fan. If the fan blade angle adjustment is not synchronized, the fan air output will be unbalanced. If the rotating parts cannot maintain dynamic balance during rotation, the fan will vibrate greatly during operation, affecting its use. Summary of the invention

The change of the use angle of the guide blade 302 changes the size of the wind flow generated by the fan assembly when the driving motor 201 is at a constant speed. The regulation is convenient and flexible. After the regulation is completed, the power of the driving motor 201 is turned on and it can be used.

[0033] In the disclosed embodiment, the cross-sectional shape of the control seat 204 is a regular polygon, and a synchronization groove 2021 is provided inside the rotating seat 202.

[0034] Specific usage and function of this embodiment: In the present invention, the installation component 1 can spray the disinfecting gas into the space to realize the operation of air sterilization, and the air supply equipment supplies the disinfecting gas into the interior of the air supply channel 1021, and finally the disinfecting gas can be sprayed out through the fumigation nozzle 103 to realize the operation of air sterilization, and under the action of the fan component, the disinfecting gas can be blown away and blown away, thereby improving the disinfection range and effect. When the driving motor 201 rotates, the driving motor 201 can drive the guide blades 302 to rotate through the rotating seat 202, thereby generating wind flow to blow the disinfecting gas away.

When the positioning rod 205 rotates, it can drive the control seat 204 to move axially through the rod body thread. When the control seat 204 moves, the control groove 2041 can drive the positioning plate 203 to rotate through the control protrusion 2032. When the positioning plate 203 rotates, the positioning groove 2031 can drive the linkage block 301 to move radially in the rotating seat 202 through the positioning lever 3012. When the linkage block 301 moves, the linkage groove 3011 can drive the guide blade 302 to rotate through the linkage protrusion 3021, thereby changing the use angle. The change of the use angle of the guide blade 302 changes the size of the wind flow generated by the fan assembly when the drive motor 201 is at a constant speed. The regulation is convenient and flexible. After the adjustment is completed, turn on the power of the drive motor 201 and it can be used.
