Detailed Description
The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the invention easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the invention.
In an embodiment of the present invention, referring to fig. 1 to 2, a charging dust collector with a lithium battery pack capable of dissipating heat rapidly includes afirst housing 1 and asecond housing 3; adust barrel component 2 is arranged in thefirst shell 1; a vacuumizingmotor 6 is arranged in thesecond shell 3; thesecond housing 3 is communicated with thefirst housing 1; anair outlet 5 is formed in thesecond shell 3, and anair duct pipe 4 is arranged in thesecond shell 3; theair duct pipe 4 is communicated with the vacuumizingmotor 6 and theair outlet 5, so that air pumped by the vacuumizingmotor 6 is directly discharged from theair outlet 5; thevacuum pumping motor 6, theair duct pipe 4 and theair outlet 5 form an independent closed air flow channel.
