[0002] A handheld dust blower is a handheld dust blower that can be operated by hand and can be used to blow air to dissipate heat from a car, blow away snow and dust, dry a pet, or blow dust off a keyboard. This type of handheld dust blower is very popular among consumers.

[0003] Since the handheld dust blower can only realize a single blowing function in actual operation, it is not easy to realize the heating or cooling processing of the wind body generated by the turbo fan inside the casing, which makes it difficult for the device to meet the operational requirements of blowing hot air or cold air, and the functionality is insufficient and the convenience is poor. Moreover, it does not have a heat-conducting heat dissipation structure for protecting the rechargeable lithium battery inside the casing. This leads to serious heat loss during long-term operation of the device, affecting its service life, and can no longer meet people's needs. Therefore, we propose a new type of handheld portable dust blower to solve the above-mentioned problems. Utility Model Content
