As shown in fig. 3, in this embodiment, the device is a vacuum cleaner, the battery pack 100 is disposed below a handle 40 of the vacuum cleaner, the blower 300 is a motor for providing suction in the vacuum cleaner, the ventilation duct 200 is a hollow handle 40 of the vacuum cleaner, and a portion of the plurality of ventilation openings 110 is in communication with the handle 40, and another portion is in direct communication with air outside the battery pack 100. The hollow handle is a part held by hands when the dust collector is held by hands.
When the dust collector works, the dust-containing air enters the dust storage chamber 50 of the dust collector from the dust suction port of the dust collector under the suction effect provided by the motor, most dust is left in the dust storage chamber 50 after being processed by the separator, and the air is blown to the inside of the battery pack through the ventilation pipeline 200 after passing through the motor to take out the heat in the battery pack, so that the temperature of the battery pack is reduced.
Because the air passing through the motor still may have a small amount of dust, if the air is directly blown to the battery pack, the battery pack may be polluted after a long time, in order to avoid the above problems, an air purification device, such as a motor filter sponge 60 and a HEPA (high efficiency air filter) assembly 70, may be disposed between the ventilation duct 200 (handle 40) and the motor, that is, the air flowing out from the motor is filtered by the air purification device and then enters the ventilation duct 200 and the battery pack 100, thereby ensuring that the heat dissipation structure of the battery pack does not affect the battery pack due to the characteristics of the dust collector when in use.
In addition, while improving the heat dissipation of the battery pack, in order to make the vacuum cleaner have better exhaust efficiency, the exhaust hole 80 may be further disposed at the air purification device of the vacuum cleaner housing, that is, the air flowing out from the motor is filtered by the air purification device and then enters the external air through the ventilation opening 110 of the battery pack 100 and the exhaust hole 80 of the air purification device. Referring to fig. 3, the hollow handle is located between the handle upper housing and the handle lower housing. The vent 80 is provided in the housing above the handle.

Specifically, an air inlet 501 is formed in a position of the dust storage chamber 50 facing the battery pack 100, and correspondingly, a part of the vent 110 is formed in a side surface of the battery pack 100 facing the dust storage chamber 50, and the vent 110 and the air inlet 501 in the dust storage chamber 50 are communicated through a hollow shell, that is, the vent 110 and the air inlet 501 are respectively formed at two ends of the hollow shell.
Preferably, the ventilation duct 200 and the battery pack 100 are integrally formed, and in order to ensure the sealing performance of the airflow path, a sealing ring 201 is arranged on the ventilation duct 200, and specifically, the sealing ring 201 is arranged at one end of the ventilation duct 200 abutting against the dust storage chamber 50. One molding method of the ventilation duct 200 is described above, but the present invention is not limited thereto, and in addition, the ventilation duct 200 may be integrally molded with the dust storage chamber 50, and the sealing ring 201 may be provided at one end of the ventilation duct 200 abutting against the battery pack 100; or, the ventilation duct 200 may be formed separately and erected between the dust storage chamber 50 and the battery pack 100, and the two ends of the ventilation duct 200 are both provided with the sealing rings 201.
In this embodiment, when the vacuum cleaner is in operation, the motor is in an on state, and under the action of suction force provided by the motor, the dust-containing air enters the dust storage chamber 50 of the vacuum cleaner from the dust suction port of the vacuum cleaner, meanwhile, the air outside the battery pack passes through the battery pack 100 and the ventilation duct 200 in sequence, enters the dust storage chamber 50 through the air inlet 501, and after being processed by the separator, the mixed air passes through the motor and then enters the outside air through the air outlet 80. When the air outside the battery pack enters the dust storage chamber 50 through the battery pack 100, the air in the battery pack 100 is driven to flow, so that the heat in the battery pack is taken out, and the temperature of the battery pack is reduced.
EXAMPLE III
FIG. 6 is a schematic structural diagram of a third embodiment of the present invention; fig. 7 is a sectional view of the third embodiment of the present invention. As shown in fig. 6 and 7, in the present embodiment, the device is an electric screwdriver, the battery pack 100 is disposed below a handle of the electric screwdriver, the blower 300 is a motor for rotating the screwdriver in the electric screwdriver, the ventilation duct 200 is a hollow housing between the battery pack 100 and the motor, and the ventilation openings 110 are partially communicated with the hollow housing and partially directly communicated with air outside the battery pack 100.
When the electric screwdriver works, the motor drives the screwdriver to rotate, generated air flows into the battery pack 100 through the ventilation opening 110 after entering the ventilation pipeline 200, and then flows to the outside air, so that heat in the battery pack is taken out, and the temperature of the battery pack is reduced.
