By setting such a gap, the air flow extrusion between the centrifugal air flow and the inner wall of the fan box can be avoided, which not only improves the air pressure and air flow but also reduces the air flow noise.

[0028] The present utility model uses an EC motor to replace the commonly used AC motor as the power output. The EC motor is manually or automatically adjusted in speed through the EC motor controller to achieve the switching of the air volume. The EC motor controller can be fixed on the frame 1 or integrated in multiple units for remote precise control.

[0029] The EC motor is fixed on the fan fixing plate 33, and the centrifugal impeller 51 is fixed on the driving shaft of the EC motor. In a direct connection mode, the power loss caused by belt drive or coupling drive is eliminated, and the operation is efficient.

[0030] The functional area 2 is internally provided with sheet metal connectors, and the sheet metal connectors are riveted to the frame. The sheet metal connectors are single or multiple. Several insertion slots 6 are provided inside the sheet metal connectors. The several insertion slots 6 include a high-efficiency filter insertion slot 61, a medium-efficiency filter insertion slot 62, a primary filter insertion slot 63, an activated carbon insertion slot 64 or an ultraviolet lamp insertion slot. Further, to improve the filtering effect and the sterilization effect, the arrangement order of the above-mentioned multiple insertion slots 6 is as follows: from one side of the centrifugal impeller 51 towards the air inlet, there are arranged a high-efficiency filter insertion slot 61, a medium-efficiency filter insertion slot 62, a primary filter insertion slot 63, an activated carbon insertion slot 64 and an ultraviolet lamp insertion slot. In this embodiment, the activated carbon insertion slot 64 and the ultraviolet lamp insertion slot can be used interchangeably.

[0035] After the present utility model adopts the above structure, the advantages thereof are summarized as follows:

[0036] 1. High efficiency and energy saving: Compared with ordinary motors, the common energy-saving motors are variable-frequency motors. Variable-frequency motors can adjust the speed according to the change of load size, reducing the power consumption. It can effectively reduce energy consumption. However, during operation, some electrical energy is still used for frequency conversion and is not used as the output kinetic energy. Therefore, the energy-saving effect is generally 20-40%. As the speed decreases, the efficiency also decreases. While the utility model adopts an EC motor, which converts alternating current into direct current through an internal converter and replaces the traditional mechanical carbon brush commutation with adjustable electronic commutation. It has high energy efficiency, stepless speed regulation in a wide range, and the energy-saving effect can reach 30-60%, and the efficiency can reach more than 90%.

[0037] 2. Environmental protection: Low operating noise. The EC motor is driven by a DC power supply, with low operating noise. The control method of the electronic circuit of the EC fan reduces the control noise and current noise existing in the traditional fan. It adopts a centrifugal impeller, with small amplitude and low noise during operation. It adopts a sealed box to further reduce the operating noise of the unit. It can be used in places with high noise requirements such as hospitals and laboratories.

[0038] 3. Precise control: Adopting an EC motor drive, its EC motor controller makes the motor speed more intelligent and digital. It can steplessly adjust and control the fan speed according to the changes of working environment temperature, wind pressure difference and other parameters, so as to obtain different air volume requirements. It can also control individual fans integrated in the network more precisely.

[0039] 4. Modular purification function, convenient conversion. The purification device is changed to be modular, plug-and-play, and easy to replace. The primary, intermediate and high-efficiency filters can be freely combined according to actual needs to meet different levels of purification requirements. An activated carbon purifier can also be configured to improve the odor in the air, or an ultraviolet disinfection lamp can be used for sterilization to meet different needs.
