[0025] like Figure 3 and Figure 5 As shown, the lower end of the dust hood 31 is rectangular, and the upper end of the dust hood 31 is cylindrical, wherein the rectangular inner cavity and the cylindrical inner cavity are smoothly connected.

[0026] like Figure 4 The lifting and lowering connecting assembly 33 includes a lifting limit sleeve 331 connected to the front and rear sides of the dust hood 31, the lifting and lowering connecting assembly 331 is movably sleeved with a lifting limit slide rod 332 inside, the upper end of the lifting and lowering connecting assembly 332 passes through the lifting and lowering connecting assembly 331 and is fixedly connected with an anti-slipping holding block 333, and a positioning spring 334 is arranged on the outside of the lifting and lowering connecting assembly 332, and the upper and lower ends of the positioning spring 334 are respectively abutted against the anti-slipping holding block 333 and the lifting and lowering connecting assembly 331; due to the arrangement of the lifting and lowering connecting assembly 33, it can not only support the dust hood 31 and ensure that there is a gap between the dust hood 31 and the ground, so that the fluff on the ground can be sucked into the dust hood 31 from bottom to top, but also avoid the situation where the staff continuously lifts the dust hood 31 and quickly consumes physical strength.

[0027] like Figure 5 and Figure 7 As shown, the lifting limit sleeve 331 is movably sleeved with a first rotating shaft 335 on one side close to the dust hood 31, and the outer diameter of one end of the first rotating shaft 335 close to the dust hood 31 is smaller than the outer diameter of the other end thereof, and the end of the first rotating shaft 335 close to the dust hood 31 passes through the lifting limit sleeve 331 and is fixedly connected to the side of the dust hood 31.

[0028] like Figure 7 and Figure 8As shown, a coaxial groove is provided on the side of the outer surface of the first rotating shaft 335 away from the dust collection hood 31, and a second spring 336 is arranged in the coaxial groove, one end of the second spring 336 is connected to the inner wall of the coaxial groove, and the other end of the second spring 336 is connected to the rotating connecting sleeve 321; due to the setting of the second spring 336, it can ensure that the lifting connection assembly 33 and the pulley assembly 34 as a whole can swing around the center line of the dust collection hood 31 with the cooperation of the first rotating shaft 335, so that the lower end of the pulley assembly 34 is deflected to the front and rear sides of the dust collection hood 31, ensuring that the lifting connection assembly 33 and the pulley assembly 34 maintain a stable tilted state, so that the dust collection hood 31 maintains a stable tilted state under the support of the lifting connection assembly 33 and the pulley assembly 34.

[0029] like Figure 5 and 7 As shown, the pulley assembly 34 includes a connecting seat 341 arranged at the bottom of the lifting limit slide bar 332, and the top of the connecting seat 341 is fixedly connected to a second rotating shaft 344, the outer diameter of the second rotating shaft 344 close to one end of the connecting seat 341 is smaller than the outer diameter of the other end, and the second rotating shaft 344 is movably sleeved on the inside of the lifting limit slide bar 332; due to the setting of the second rotating shaft 344, when the dust hood 31 is moved forward and backward, the roller 343 can rotate around the axis of the lifting limit slide bar 332, that is, the roller 343 can be deflected to the front and rear sides of the center line of the dust hood 31, and then when the dust hood 31 is pressed down, it can be tilted under the support of the lifting connecting assembly 33 and the pulley assembly 34.

[0030] like Figure 7 As shown, the bottom of the connecting seat 341 is fixedly connected to two front and rear connecting frames 342, and the lower end of the connecting frame 342 is movably connected to a roller 343, the axis of the roller 343 does not intersect with the axis of the lifting limit slide bar 332, and the outer surface of the roller 343 is a non-rough structure; due to the setting of the pulley assembly 34, the dust hood 31 can be moved forward and backward so that the pulley assembly 34 can be offset to the front and rear sides of the center line of the dust hood 31, and then when the multi-section control dust suction pipe 2 and the dust suction hood 31 are pressed down, the front and rear sides of the dust suction hood 31 can be tilted downward under the support of the lifting connecting assembly 33 and the pulley assembly 34, so that the dust suction hood 31 can scrape up the fluff on the ground when it moves forward and backward, which helps to improve the efficiency of the fluff being sucked in and improve the dust suction effect.

[0031] like Figure 4 and Figure 7As shown, the elastic strength of the second clockwork spring 336 is less than the elastic strength of the positioning spring 334, and the front and rear sides of the dust hood 31 are fixedly connected with two limit levers 337 located on the left and right sides of the lifting limit slide bar 332, the positioning spring 334 and the lifting connection assembly 33 rotate around the first rotation axis 335, and finally the outer surface of the lifting limit slide bar 332 conflicts with the outer surface of the limit lever 337; due to the setting of the limit lever 337, the dust hood 31 is pressed down so that it can have a maximum tilt angle when it tilts back and forth under the lifting connection assembly 33 and the pulley assembly 34, so that while ensuring the tilt, the height between the dust hood 31 and the ground can be controlled by the elasticity of the second rotation axis 344, thereby ensuring that larger foreign matter can be sucked into the dust hood 31 in time.

[0032] The working principle and use process of the present invention: The movement of the detachable rotary dust suction head 3 is controlled by the multi-section control dust suction pipe 2. After the device is turned on by the controller 4, the cotton wool can be sucked into the detachable filter dust suction cylinder 1 under the cooperation of the multi-section control dust suction pipe 2 and the detachable rotary dust suction head 3. When the dust hood 31 needs to be inserted into the narrow gap, one end of the dust hood 31 is controlled to press against the front end of the narrow gap through the multi-section controlled dust suction pipe 2, and then the multi-section controlled dust suction pipe 2 is moved to make it rotate relative to the dust hood 31 under the cooperation of the rotation positioning assembly 32, until the long axis of the dust hood 31 is close to being parallel to the plane where the multi-section controlled dust suction pipe 2 is located, at this time, the dust hood 31 can be inserted into the gap along the edge of the narrow gap, and then the multi-section controlled dust suction pipe 2 is moved downward to make the dust hood 31 absorb foreign matter on the ground in the narrow gap; When the dust hood 31 needs to be extended into a low space, one end of the dust hood 31 is first inserted into the low space, and then the multi-section controlled dust suction pipe 2 is moved upward. At this time, the dust hood 31 is restricted by the top of the low space, so that the operating connecting pipe 21 and the dust hood 31 can be relatively moved, and then the universal telescopic tube 22 is stretched and the rotation positioning linkage sleeve 24 is separated from the operating connecting pipe 21. At this time, the multi-section controlled dust suction pipe 2 is moved downward to make the dust hood 31 close to the surface, and the multi-section controlled dust suction pipe 2 is continued to be moved downward to make it swing relative to the dust hood 31, so that the dust hood 31 is attached to the ground, and the multi-section controlled dust suction pipe 2 can continue to move downward to ensure that the detachable rotary dust suction head 3 can be extended into the low space through the multi-section controlled dust suction pipe 2; When the dust hood 31 needs to be tilted so that it can better hang the cotton wool to improve the suction effect, the dust hood 31 is first moved backward by the multi-section control dust suction tube 2. Under the restriction of the ground, the roller 343 is deflected to the front of the center line of the dust hood 31 under the cooperation of the second rotating shaft 344. At this time, the multi-section control dust suction tube 2 can be pressed down to tilt the dust hood 31 under the support of the lifting connection assembly 33 and the pulley assembly 34 and the ground, and ensure that the front end of the dust hood 31 is higher than the rear end. At this time, moving the dust hood 31 forward and backward can ensure that the larger cotton wool in the front can enter the area below the dust hood 31 from the bottom of the front end of the dust hood 31, while preventing the cotton wool from escaping from the rear end below the dust hood 31, thereby ensuring that the larger cotton wool can be smoothly sucked into the dust hood 31; conversely, it can be moved backward to smoothly suck in the larger cotton wool; By continuously moving the multi-section controlled dust suction pipe 2 downward, the dust suction cover 31 can be brought close to the ground under the elastic connection of the positioning spring 334, ensuring that the fixed suction force can quickly absorb small and heavy foreign objects.
