[0007] Fan shell, the fan shell is fixed together with the battery shell, the fan shell is equipped with fan containing cavity in it, both sides of the fan containing cavity are equipped with air inlet and air outlet respectively, the fan containing cavity is installed with fan base, the fan base is equipped with negative pressure inlet, the negative pressure inlet is communicated with the air inlet, the fan base is installed with negative pressure fan;

[0008] Ventilation support, the ventilation support is equipped with communication channel, the communication channel includes communication inlet and communication outlet, the communication inlet is communicated with the battery ventilation channel, the communication outlet is communicated with the negative pressure inlet.

[0009] Further, the air inlet is symmetrically arranged on the two side walls of the battery shell.

[0010] Further, the area of the air inlet is 66.8 square millimeters.

[0011] Also disclosed is a dust collector comprising the above battery pack air suction cooling device.

[0012] Compared with the prior art, the utility model has the beneficial effects that:

[0013] (1) When the negative pressure fan is started, the environmental airflow enters the battery ventilation channel from the air inlet, the airflow carries away the heat of the battery pack through the battery ventilation channel, then the airflow passes through the communication channel and the negative pressure inlet, and finally is discharged into the environment from the air outlet, so that the efficiency of the air cooling mode is relatively high;

[0014] (2) The environmental airflow enters from the two side walls of the battery shell and then cools the battery pack, so that the cooling is more uniform;

[0015] (3) The negative pressure fan can play the role of dust absorption and cooling the battery pack. BRIEF DESCRIPTION OF DRAWINGS
