Fig.11 The present invention Fig. 9 The cross-sectional view of the FF line, Fig.12 The present invention Fig. 9 Sectional view along the GG line.

[0043] The present invention provides a multi-switch controlled handheld push rod wireless vacuum cleaner, wherein the dust collection mechanism 101 comprises a dust collection seat 301 and a collection barrel, wherein the dust collection seat 301 has a dust collection chamber 303, two mounting chambers 304 and a guide chamber 305, wherein the dust collection seat 301 is further provided with two second motors 306, wherein the output end of the second motor 306 is provided with a turbine blade 307, and the turbine blade 307 extends into the corresponding mounting chamber 304, wherein the rear end face of the dust collection seat 301 is connected with a hose 308, a bellows 309 is provided below the collection barrel, and the vertical rod 2 05 is fixedly connected to the dust suction seat 301 and is located above the dust suction seat 301. The hose 308 is connected to the bellows 309 and is located at the end of the bellows 309 away from the collecting cylinder. The collecting cylinder is fixedly connected to the adjusting cylinder 104 and is located on the outside of the adjusting cylinder 104. The dust suction seat 301 is used as the core part of the dust suction mechanism 101, which integrates the dust suction chamber 303, the installation chamber 304 and the guide chamber 305, so that the entire dust suction mechanism 101 is compact in structure and fully functional. The dust suction chamber 303 is used to The installation cavity 304 is used to install the second motor 306 and the turbine blades 307, and the guide cavity 305 is used to guide the airflow channel. The collection cylinder is used to collect and store dust and debris sucked from the dust suction cavity 303. Its design allows the user to easily empty and clean the collection cylinder, thereby maintaining the continuous and efficient operation of the dust suction mechanism 101. The second motor 306 is used as a power source to drive the turbine blades 307. It provides the necessary speed and torque to generate strong suction. The turbine blades 307 are connected to the second motor 306. 6, the turbine blades 307 rotate at a high speed to generate airflow and form a low-pressure area in the dust suction chamber 303, thereby sucking in dust and debris. The design of the turbine blades 307 enables the dust suction mechanism 101 to have higher suction power and efficiency. The hose 308 connects the dust suction seat 301 and the bellows 309, providing a certain flexibility and length, so that the user can operate the dust suction mechanism 101 more conveniently and cover a wider area. The retractable nature of the bellows 309 makes the dust suction mechanism 101 more flexible in adapting to different heights and angles.

[0044] The collecting barrel comprises a collecting cover 310, a threaded cover 311 and a barrel 302. A vertical pipe 312 is arranged at the inner bottom of the collecting cover 310. A filter screen 313 is arranged on the threaded cover 311. The bellows 309 extends to the inner bottom of the barrel 302. The collecting cover 310 is slidably connected with the barrel 302 and is located inside the barrel 302. The vertical pipe 312 is sleeved on the bellows 309. The threaded cover 311 is threadedly connected with the barrel 302 and covers the barrel 302. The barrel 302 is fixedly connected with the adjusting barrel 104 and is located inside the adjusting barrel 104. The outer side of the cylinder 302 is slidably connected to the collection hood 310, which may be used to guide the sucked dust and debris into the interior of the cylinder 302. Its design allows the user to easily disassemble and clean the collection hood 310. The vertical pipe 312 is sleeved on the bellows 309, ensuring a stable connection between the bellows 309 and the collection cylinder, while preventing the leakage of dust and debris. The threaded cap 311 is threadedly connected to the cylinder 302 and covers the cylinder 302, playing a sealing role. The filter screen 313 is used to filter out larger dust particles to prevent them from being discharged.

[0045] The dust suction chamber 303 is located at one end of the two installation chambers 304 , the guide chamber 305 is located at the other end of the two installation chambers 304 , and the dust suction chamber 303 , the two installation chambers 304 and the guide chamber 305 are in communication.

[0046] When using a multi-switch controlled handheld push rod cordless vacuum cleaner of the present embodiment, first start the two second motors 306 in the dust collection mechanism 101. After the second motor 306 is started, its output end drives the turbine blades 307 to start high-speed rotation. The rotation of the turbine blades 307 generates a strong airflow, so that a negative pressure is formed inside the dust collection chamber 303. Due to the negative pressure formed inside the dust collection chamber 303, external air and dust are sucked into the dust collection chamber 303, and the dust collection chamber 303 is connected with the two installation chambers 304 and the guide chamber 305, ensuring the smooth flow of airflow. The sucked air and dust enter the bellows 309 through the hose 308 and finally enter the collection barrel. The dust and air entering the collection barrel first encounter the filter 313, and the filter 313 is used to filter out larger dust particles to prevent them from being discharged. The filtered air is discharged from the filter 313, and the dust is deposited in the collection cover 310.
