The inner wall of the first sliding arc groove 92 away from the plug-in groove 91 is provided with a connecting magnet 94.

[0040] With reference to Figure 1 and Figure 2 , when cleaning, when dust suction is needed, the dust collector body 1 is controlled by the switch, the vacuum generator 21 is started to form negative pressure, and external dust enters the dust collecting cylinder 22 through the dust collecting pipe 23. The dust enters the fixed cone cylinder 8 through the dust inlet 81 under the action of negative pressure and adheres to the filter cone cylinder 6, and the setting of the filter cone cylinder 6 reduces the possibility of blockage of the device. Since the fixed cone cylinder 8 is detachably connected with the connecting ring 5 and the dust collecting cylinder 22 is detachably connected with the device shell 101, it is convenient for the operator to replace and clean the filter cone cylinder 6. Figure 3 According to different needs, the mounting sleeve 24 is mounted at the end of the dust collecting pipe 23, and the user can use the cleaning brush 25 arranged on the mounting sleeve 24 to clean the dust first. The setting of the clamping groove 41 and the sealing gasket 42 improves the sealing performance of the mounting sleeve 24 and the dust collecting pipe 23.

[0041] With reference to Figure 1 and Figure 2When it is needed to blow dust in small gaps, the switch is used to control the dust blowing fan 31 to be turned on. The airflow is blown out through the dust blowing port 104, the dust blowing cone cylinder 32 and the dust blowing pipe 33 to blow dust in the gaps. The setting of the dust blowing lamp 35 facilitates the user to observe the dust range in dark places. For some positions where it is inconvenient to extend the handheld dust collector, the connecting pipe 10 can be connected to the dust blowing pipe 33, and the user holds the gas delivery box 12 to blow dust in the dust part. The setting of the dust blowing assembly 3 and the dust collecting assembly 2 meets different cleaning requirements.

[0042] Referring to Figure 2 , Figure 4 and Figure 5 When the connecting pipe 10 is connected, the connecting piece is pushed into the plug-in slot 91, and the connecting pipe 10 is screwed. The limiting rod 15 is embedded in the first sliding arc slot 92, and the sliding rod 14 is embedded in the second sliding arc slot 93. The connecting magnet 94 adsorbs the connecting piece, which reduces the possibility of separation of the connecting pipe 10 and the abutting ring 9.

[0043] The implementation principle of the handheld dust collector with dust collecting and blowing functions in the embodiment of the application is as follows: when cleaning, the dust collector body 1 is controlled by the switch when it is needed to suck dust. The vacuum generator 21 is started to form negative pressure, and the external dust enters the dust collecting cylinder 22 through the dust collecting pipe 23. According to different use needs, the mounting cylinder is mounted at the end of the dust collecting pipe 23. The user can use the cleaning brush 25 arranged on the mounting sleeve 24 to clean the dust first. When it is needed to blow dust in small gaps, the dust blowing fan 31 is turned on. The airflow is blown out through the dust blowing port 104, the dust blowing cone cylinder 32 and the dust blowing pipe 33 to blow dust in the gaps. For some positions where it is inconvenient to extend the handheld dust collector, the connecting pipe 10 can be connected to the dust blowing pipe 33, and the user holds the gas delivery box 12 to blow dust in the dust part.

[0044] The above are the preferred embodiments of the application, which do not limit the protection scope of the application. Therefore, equivalent changes made on the basis of the structure, shape and principle of the application should be covered by the protection scope of the application.
