Description

Technical Field

[0001] The utility model relates to the field of battery accessories, in particular to a dustproof ventilation device for an energy storage power source. Background Art

[0002] As people's living standards improve, they are more interested in returning to nature and experiencing life in the great outdoors. As a result, more and more derivative products designed for camping and picnicking are available on the market. When traveling, many electronic devices are used, and these devices need to be powered by energy storage power supplies. Mobile energy storage power supplies have become a must-have product for people's travel and tourism.

[0003] Most of the existing energy storage power supplies that can supply power to high-power electrical appliances include a box, in which a high-power battery pack is arranged. The battery pack is electrically connected to the socket on the box, and an air inlet is provided on the box. External cold air is sucked into the box through a fan to dissipate heat for the battery pack in the box, so that the energy storage power supply can reduce the temperature generated by the battery pack during discharge when supplying power to high-power electrical appliances.

[0004] Since cold air enters the energy storage power source through the air inlet, in order to prevent external dust and metal particles from entering the energy storage battery and affecting the operation of the battery pack, a filter is usually installed at the air inlet. However, after the energy storage battery has been used for a period of time, too much dust will accumulate on the filter, affecting the ventilation efficiency of the filter, reducing the amount of cold air entering the energy storage battery and making it impossible to cool the battery pack in time, posing certain safety hazards.

When dust accumulates too much on one of the first filter screens, the first fan and the second fan both reverse together, pushing the first column to rotate, and the second fan rotates and moves from the first vent into the second air duct, sucks cold air from another first filter screen into the second air duct and discharges it into the receiving chamber, and the first fan sucks part of the air in the second air duct into the first air duct to blow away dust on one of the first filter screens; when dust accumulates too much on the other first filter screen, the first fan and the second fan both rotate forward together, pushing the first column to rotate, and the first fan rotates and moves from the first vent into the first air duct, sucks cold air from one of the first filter screens into the first air duct and discharges it into the receiving chamber, and the second fan sucks part of the air in the first air duct into the second air duct to blow away dust on the other first filter screen, thereby automatically cleaning the dust on the two first filter screens and improving the ventilation efficiency of the first filter screens.
