Specifically, the fan mechanism is installed on one side of the filter element mechanism 51, an air duct 525 is arranged on the air inlet side of the fan 521, and an axial gap 526 is arranged between the fan 521 and the air duct 525, so that an emergency air duct can be formed between the fan 521 and the air duct 525, when the filter element 512 is blocked, namely the inner cavity of the filter element 512 can not suck air through the peripheral wall of the filter element 512, the corresponding air inlet cavity 5241 can not suck air from the inner cavity of the filter element 512, at the moment, the fan 521 sucks air from the outside through the axial gap 526, the situation that the negative pressure of the air inlet cavity 5241 is too large to burn out the fan 521 due to continuous air suction from the air inlet cavity 5241 is avoided, the overload protection effect of the fan 521 is realized, and the service life of the fan 521 can be effectively.
Optionally, the outer peripheral wall of the fan 521 is stepped in the axial direction, the fan 521 includes a large end 5211 located above and a small end 5212 located below, a stepped surface 5213 is provided between the large end 5211 and the small end 5212, a radial gap 527 is formed between the stepped surface 5213 and the upper surface of the air duct 525 or the upper surface of the air inlet cover 524, and the radial gap 527 is communicated with the axial gap 526. Specifically, radial clearance 527 and axial clearance 526 form the emergent wind channel of bending, under the prerequisite of guaranteeing the overload protection effect of fan 521, make emergent wind channel have certain circulation resistance, and then guarantee more reliably that fan mechanism can form the negative pressure at the inner chamber of filter core mechanism 51, and then realize the dust absorption efficiency of filter core mechanism 51.
The air duct 525 is stepped and comprises a flange portion and an air duct portion, the flange portion of the air duct 525 abuts against the upper surface or the lower surface of the air inlet cover 524, the air duct 525 is fixedly connected with the air inlet cover 524 through the flange portion, and the air duct portion extends into the air inlet cavity 5241 below the air inlet cover 524. When the flange portion of the air duct 525 abuts against the upper surface of the air inlet cover 524, the upper surface of the flange portion is the upper surface of the air duct 525, a radial gap 527 is formed between the stepped surface 5213 of the fan 521 and the upper surface of the air duct 525, and when the flange portion of the air duct 525 abuts against the lower surface of the top portion of the air inlet cover 524, a radial gap is formed between the stepped surface 5213 of the fan 521 and the upper surface of the air inlet cover 524. The air duct 525 and the air inlet cover 524 which are formed in a split mode can simplify the structure of parts, facilitate the simplification of a forming die of the parts and reduce the manufacturing difficulty. In other embodiments, the following structure is also possible: the air duct and the air inlet cover are integrally formed. In this case, a radial gap is formed between the stepped surface of the fan and the upper surface of the integrally formed air inlet cover assembly. The air duct 525 and the air inlet cover 524 which are integrally formed can simplify the assembly process and improve the assembly efficiency.
