[0024] In this embodiment, as Figure 1 and Figure 2 As shown, the gun-type main body 10 includes a gun body 11 and a gun handle 12 connected to the axial rear end of the gun body 11. The gun body 11 has a dust suction port 111 at its front end. The dust cup 20 is located below the front end of the gun body 11, and a suction channel is constructed between the dust suction port 111 of the gun body 11 and the air inlet of the dust cup 20. Specifically, the front part of the gun body 11 has a channel communicating with the dust suction port 111, and the channel has an opening at its rear end bottom wall. The air inlet of the dust cup 20 is located at its top and is connected to the opening of the channel. The fan assembly 30 is located below the gun body 11 on the rear side of the dust cup 20. The fan assembly 30 includes a fan housing 31 and a fan 32 disposed inside the fan housing 31. The air inlet of the fan 32 is connected to the dust cup. The air outlet of the 20 is connected and a filter component is provided between them.

[0028] Compared with the prior art, the present invention has a simple and reasonable structure. The battery pack can be stably installed on the mounting part between the fan housing and the gun handle by the T-shaped slider and the sliding port. At the same time, the battery pack supplies power to the fan assembly through the connection of the first connector and the second connector. Furthermore, the airflow discharged from the fan assembly can be introduced into the battery pack through the connection of the first heat dissipation hole and the second heat dissipation hole to quickly remove heat, so that the battery pack is in a relatively low operating temperature range. This ensures the discharge effect and battery life of the battery pack, thereby ensuring the working performance of the vacuum cleaner.
