[0038] As an optional implementation manner of the utility model, the buffering mechanism includes a conical filter screen 3 installed at the position where the air inlet 2 communicates with the purification chamber, and the small head end of the conical filter screen 3 faces the starting end of the air inlet 2; the large head end specification of the conical filter screen 3 is the same as the specification of the air inlet 2.

[0039] Such as Figure 2 As shown, specifically, the conical filter screen 3 is a conical structure, the pointed end faces the inlet position of the air inlet 2, and filter holes are uniformly arranged on the entire conical surface of the conical filter screen 3.

[0040] Such as Figure 2 As shown, a fixing plate 4 is arranged in the purification chamber to divide the purification chamber into a first chamber 5 and a second chamber 6; the suction assembly includes an aluminum shell motor 7 and a centrifugal impeller 8; the aluminum shell motor 7 is horizontally arranged at the position of the second chamber 6 and is connected to the fixing plate 4. In order to achieve sealed air flow, as shown in Figure 2 And Figure 6 As shown, the aluminum shell motor 7 has a surrounding wall on its periphery, and the surrounding wall and the machine body 1 enclose the second chamber 6, and the second chamber 6 is a circular ring structure. As shown in Figure 4 As shown (the arrow indicates the flow direction of the air flow in the second chamber 6), the air flow circulates in the circular second chamber 6 on the periphery of the aluminum shell motor 7; the centrifugal impeller 8 is arranged in the first chamber 5 and is connected to the output shaft of the aluminum shell motor 7; there is a gap between the bottom of the fixing plate 4 and the bottom wall of the purification chamber for the air flow to pass through.

[0041] The utility model adopts a built-in centrifugal impeller (fan blade centrifugal type) with a balancing accuracy of 0.2mm / s, a high protection IP54 grade aluminum shell motor and a thermal protector (built on the motor) for reasonable matching, which can make the equipment stable and reliable for long-term use.
