[0028] It is also worth mentioning that the motor 7 and the battery pack 9 are both connected to the button 23 with wires. A cyclone separator 22 is provided at one end of the motor 7. Part of the wires for connecting the motor 7 and the battery pack 9 are stored in the connecting shell 25. The user can press the button 23 to supply the electric energy of the battery pack 9 to the motor 7 through the wires, thereby starting the motor 7 and generating negative pressure.

[0029] And further, if Figures 1 to 6 As shown, the connecting shell 25, the filter shell 10, the handpiece 1 and the battery shell 5 are fixedly connected in sequence, the heat dissipation duct 6 is clamped in the connection 16 and penetrates the connecting shell 25, the filter shell 10 and the battery shell 5 are arranged in parallel in the same plane, one end of the motor shell 2 is connected with the filter shell 10, one end of the heat dissipation duct 6 penetrates the connecting shell 25 and enters the inner cavity of the filter shell 10, and the other end of the heat dissipation duct 6 penetrates the connecting shell 25 and enters the inner cavity of the motor shell 2, and the filter shell 10 is connected with the battery shell 5 through the heat dissipation duct 6; in actual application, the negative pressure generated by the motor 7 causes the external airflow to carry dust through the air inlet duct 4 and be sucked into the dust cup 3, and the dust is separated from the airflow by the cyclone separator 22 and accumulated in the dust cup 3, and the filtered airflow enters the motor shell 2 through the motor 7, and then the airflow enters the filter shell 10 connected with the motor shell 2, and finally enters the battery shell 5 through the heat dissipation duct 6, so that a flowing airflow is generated in the battery shell 5, and the flow of the airflow in the battery shell 5 can effectively reduce the temperature of the battery pack, thereby enhancing the service life of the battery pack 9 and improving the user experience.

[0030] like Figures 1 to 6As shown, an air storage chamber 11 is provided in the filter shell 10, an air outlet 12 is provided at one end of the motor cover 8, the motor cover 8 is connected with the air storage chamber 11 through the air outlet 12, and a filter cotton 13 is provided at one end of the air storage chamber 11; wherein, an air guide port 15 is provided on an inner wall of one side of the air storage chamber 11, the air guide port 15 is connected with one end of the heat dissipation duct 6, and the heat dissipation duct 6 is made of high-temperature resistant rubber material; in this embodiment, the motor cover 8 and the air storage chamber 11 are correspondingly connected through the air outlet 12, and the filter cotton 13 is arranged at one end close to the motor cover 8. In actual application of this embodiment, the airflow is secondary filtered through the filter cotton 13, and the airflow after secondary filtration is stored in the air storage chamber 11, so that a cleaner airflow enters the battery shell 5 through the heat dissipation duct 6.

[0031] like Figures 1 to 6 As shown, an air guide tube 14 is provided in the air storage chamber 11, and a plurality of air guide plates 24 are provided on the air guide tube 14 at intervals, and a gap exists between the air guide tube 14 and the air storage chamber 11; in this embodiment, the air guide plates 24 are all tilted on the air guide tube 14, so that the airflow entering the air storage chamber 11 is blown toward the inner wall of the air storage chamber 11 through the air guide plates 24, and flows along the inner wall, so that the airflow can flow out of the air storage chamber 11 through the air outlet 12.

[0032] like Figures 1 to 6 As shown, the battery shell 5 is provided with an air inlet 16 for communicating with the heat dissipation duct 6, and the air inlet 16 is provided with an arc-shaped wind guide plate 17, which extends from the edge of the air inlet 16 to the bottom of the inner cavity of the motor shell 2; in this embodiment, the wind guide plate 17 is used to guide the airflow entering the battery shell 5. After the airflow flows out of the heat dissipation duct 6, the airflow is blown to the bottom of the battery pack 9 through the air guide plate 17, thereby increasing the contact area of ​​the airflow with the battery pack 9, avoiding the airflow only flowing on the upper surface of the battery pack 9, and enhancing the heat dissipation effect of the airflow on the battery pack 9.

[0033] like Figures 1 to 6 As shown, an air outlet window 18 is provided on either side of the battery shell 5; in this embodiment, the air outlet window 18 is provided to facilitate the airflow in the motor shell 2 to flow out of this embodiment with the heat, thereby enhancing the fluidity of the airflow in the battery shell 5 and preventing excessive accumulation of airflow and heat in the battery shell 5 to affect the service life of the battery pack 9.

[0034] like Figures 1 to 6 As shown, the dust cup 3 is detachably connected to the motor housing 2; in this embodiment, the dust cup 3 is detachably connected to the battery housing 5, which makes it convenient for the user to remove the dust cup 3 to empty the dust.

[0036] Working principle: By pressing the button 23, the electric energy of the battery pack 9 is supplied to the motor 7 through the wires, so that the motor 7 starts in the motor housing 8 and generates negative pressure. The negative pressure generated by the motor 7 passes through the air inlet duct 4, so that the external airflow entrains dust and is sucked into the dust cup 3. The dust is separated from the airflow by the cyclone separator 22 and accumulates in the dust cup 3. The filtered airflow enters the motor housing 2 through the motor 7, and then enters the filter housing 10 connected to the motor housing 2, and finally enters the battery housing 5 through the heat dissipation duct 6. After entering the battery housing 5, the airflow is blown to the bottom of the battery pack 9 through the wind guide plate 17, thereby increasing the flow area of ​​the airflow on the battery pack 9 and effectively reducing the temperature of the battery pack 9.
