DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1 and Figure 3 In this embodiment, a dust removal device for daily maintenance of electrical equipment includes a box body 1. The inner cavity of the box body 1 is provided with a telescopic mechanism 2 for realizing a telescopic function to improve the dust removal effect. The inner cavity of the box body 1 is provided with a pipe assembly 3 for cooperating with the telescopic mechanism 2 for length adjustment. The left side of the box body 1 is provided with a filter assembly 4 for fully filtering dust. A handle 5 is fixed to the outer surface of the box body 1. The handle 5 is wavy. This design can make the handle 5 fit the fingers better and improve the comfort and stability of holding.

[0023] It can be known that a vent is provided on the left side wall of the box body 1, and a connecting hole is provided on the right side wall of the box body 1. The vent and the connecting hole are located on the same axis. The same axis can ensure that dust passes through smoothly, thereby increasing the probability of dust passing through the pipe assembly 3 and being further captured by the filter assembly 4. The vent and the connecting hole are both connected to the inner cavity of the box body 1.

[0024] In addition, the telescopic mechanism 2 includes a micro motor 201 fixed to the left side wall of the inner cavity of the box body 1. The output shaft of the micro motor 201 is fixed with a threaded rod 202. The threaded transmission has good stability and can enable the moving part 203 to move more smoothly. The outer surface of the threaded rod 202 is provided with a moving part 203. The moving part 203 is composed of a moving ring, a T-block and a stabilizing block. The inner side of the moving part 203 is provided with a transmission part 204.

[0025] It needs to be further explained that a threaded hole is provided on the movable ring, and the movable ring is threadedly connected to the threaded rod 202. The threaded hole cooperates with the threaded rod 202, and under the joint action of the T-block limiter, the movable ring can be promoted to operate stably, thereby ensuring the smooth movement of the exhaust duct 303, so as to clean dust close to the dead corner. The right side of the threaded rod 202 is rotatably connected to the right side wall of the inner cavity of the box body 1 through a bearing, the bottom of the movable ring is fixed to the T-block, and the stabilizing block is fixed to the bottom wall of the inner cavity of the box body 1. A movable groove is provided on the stabilizing block, and the movable groove is adapted to the T-block.

[0026] Furthermore, the transmission part 204 includes a transmission tube 2041 fixed to the inner side of the movable ring, a fixed tube 2042 is fixed to the right side wall of the box body 1, the fixed tube 2042 is located on the outside of the transmission tube 2041 and is coaxial with the transmission tube 2041, a dust block 2043 is fixed to the right side of the transmission tube 2041, the dust block 2043 is composed of a stabilizing ring and a plurality of dust-proof bristles, the stabilizing ring is fixed to the transmission tube 2041, a plurality of dust-proof bristles are inserted on the right side of the stabilizing ring, and the transmission tube 2041 is fixed to the exhaust duct 303.

[0027] In this embodiment, when the exhaust duct 303 is close to the electrical equipment, the dust-proof bristles can provide a certain supporting force and can block external dust, ensuring that the position that needs to be cleaned is clean, thereby effectively improving the cleaning effect.

[0028] See also Figure 1 and Figure 2 In order to ensure that dust is intercepted smoothly, the pipe assembly 3 in this embodiment includes a stable pipe 301 fixed to the right side wall of the box body 1. The right side of the stable pipe 301 is fixedly connected to a bellows 302. The bellows 302 can be stretched as the exhaust pipe 303 moves to ensure that the exhaust pipe 303 moves smoothly. The right side of the bellows 302 is fixedly connected to the exhaust pipe 303.

[0029] In addition, the filter assembly 4 includes an outer shell 401 fixedly connected to the left side wall of the box body 1, and the inner side thereof is abutted with a first-stage filter plate 402, a second-stage filter plate 403 and a third-stage filter plate 404 from right to left. The first-stage filter plate 402, the second-stage filter plate 403 and the third-stage filter plate 404 are each provided with a plurality of filter holes, and the diameters of the filter holes decrease successively, so that the dust can be intercepted to the maximum extent and the interception accuracy is improved. An exhaust fan 405 is fixed to the right side wall of the inner cavity of the outer shell 401.

[0030] It should be further explained that a plurality of circulation holes are provided on the outer shell 401, and pull rings are fixed on the primary filter plate 402, the secondary filter plate 403 and the tertiary filter plate 404. The pull rings can facilitate the removal of the primary filter plate 402, the secondary filter plate 403 and the tertiary filter plate 404, thereby effectively improving the ease of cleaning. A battery slot is provided on the rear side of the box body 1, and a battery pack is fixed in the battery slot.

[0031] In this embodiment, the device ensures the patency of the dust circulation channel through the cooperation of the filter component 4 and the pipe component 3, and intercepts the dust to the greatest extent through the filter component 4, ensuring that the wind blown out from the right side of the shell 401 is as clean as possible, effectively protecting the staff.

[0032] It can be understood that the device effectively improves the dust removal effect through the cooperation of the telescopic mechanism 2 and the pipe assembly 3, can extend the exhaust duct 303 to a deeper level for dust removal, effectively improves the dust removal effect, and intercepts the dust through the filter assembly 4, which is convenient for subsequent cleaning.

[0033] The electrical components mentioned in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The power supply provided by the battery is also common knowledge in this field. Moreover, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0034] The working principle of the above embodiment is:

[0035] During use, the micro motor 201 can be controlled according to specific circumstances. The micro motor 201 prompts the threaded rod 202 to rotate. Under the joint action of the threaded rod 202 and the stabilizing block, the moving ring is prompted to move. During the movement of the moving ring, the transmission tube 2041 will be driven to move. The transmission tube 2041 can further promote the movement of the exhaust duct 303, and the bellows 302 will be stretched during the movement of the exhaust duct 303. Therefore, the gas flow inside the pipe assembly 3 can be kept smooth. Then the exhaust fan 405 is started. The exhaust fan 405 sucks in the dust and can promote the dust to be retained as much as possible through the joint action of the primary filter plate 402, the secondary filter plate 403 and the tertiary filter plate 404. When cleaning is needed, just remove the outer shell 401 and pull the pull ring in sequence. The device has good cleaning effect and is easy to use.
