Problems solved by technology
[0002] According to any lithium battery rechargeable vacuum cleaner currently on the market, its lithium battery pack will continue to heat up at high temperatures when the vacuum cleaner is working, and some may even cause battery damage due to the continuous rise in temperature of the lithium battery pack during the power supply process. The temperature in the group is too high and the protection device in the lithium battery pack is turned on to stop the external power supply. Moreover, a large amount of electric energy in the lithium battery pack cannot be released at this time.
As a result, the vacuum cleaner suddenly stops working during use
It brings great inconvenience to users, and even thinks it is a quality problem of the product

The invention discloses a rechargeable vacuum cleaner capable of rapidly dissipating heat from a lithium battery pack, which comprises a first casing and a second casing; a dust bucket assembly is arranged in the first casing; a vacuum motor is arranged in the second casing The second housing communicates with the first housing; the second housing is provided with an air outlet, and the second housing is provided with an air duct; the vacuum motor, the air duct and the outlet The air hole forms an independently closed air flow channel; the outer wall of the second housing is provided with a lithium battery pack casing; the lithium battery pack casing is provided with a lithium battery pack; the lithium battery pack provides electric energy for the vacuum motor ; The lithium battery pack casing is provided with a lithium battery pack air inlet hole and a lithium battery pack air outlet hole; during work, the airflow can enter the lithium battery pack casing from the lithium battery pack air inlet hole, and then from the lithium battery pack air outlet hole It flows into the air duct pipe and flows out of the air hole together with the wind discharged from the air duct pipe to protect the lithium battery pack; the invention can quickly dissipate heat from the lithium battery pack.
Description
technical field [0001] The invention relates to an improvement of a rechargeable vacuum cleaner, in particular to a method that can continuously and continuously take the heat generated by the lithium battery pack out of the body of the vacuum cleaner together with the wind discharged from the air duct, so that the temperature of the lithium battery pack can be kept in time. Get a certain control so that the lithium battery pack within the required range can quickly dissipate heat from the rechargeable vacuum cleaner. Background technique [0002] According to any lithium battery rechargeable vacuum cleaner currently on the market, its lithium battery pack will continue to heat up at high temperatures when the vacuum cleaner is working, and some may even cause battery damage due to the continuous rise in temperature of the lithium battery pack during the power supply process. The temperature in the group is too high and the protection device in the lithium battery pack is tu...
