[0027] Compared with the prior art, the dust removal device for the return air duct of a laminar flow operating room of the present invention has the following advantages:

[0028] By setting up the dust removal mechanism and displacement mechanism, the dust removal device can be moved in the return air duct along the length direction of the return air duct. While moving, the dust removal device can also clean the cloth dressings accumulated on the inner wall of the duct body 100. Through this mobile cleaning method, the dust removal device can clean the deep inner wall of the return air duct more conveniently and comprehensively.

[0029] The above-mentioned return air duct dust removal device for laminar flow operating rooms has the advantages of simple structure and easy implementation. It is suitable for installation and use in the existing return air duct of laminar flow operating rooms, and has low operating costs, which can improve the use efficiency.

[0030] In this embodiment, Figure 2-Figure 5 As shown, the dust removal mechanism includes a carrier plate 210 and a dust removal plate 220. The carrier plate 210 is installed on the track wall 110 and can slide along the length direction of the pipeline body 100. The dust removal plate 220 is installed on the carrier plate 210. The plate surface of the dust removal plate 220 can be parallel to the cross-section of the pipeline body 100. Bristles 221 are arranged around the periphery of the dust removal plate 220, and the bristles 221 can extend to the inner wall of the pipeline body 100.

[0031] During implementation, the carrier plate 210 is disposed parallel to the track wall 110 .

[0032] In this way, the inner wall of the pipe body 100 can be cleaned through the carrier plate 210, the dust removal plate 220 and the bristles 221, and the carrier plate 210 can drive the dust removal plate 220 to move along the length direction of the pipe body 100, so that the dust removal plate 220 and the bristles 221 can contact the inner wall of the pipe body 100 more comprehensively.

[0033] In this embodiment, Figure 2-Figure 5 As shown, one side of the dust removal plate 220 has a transmission shaft, and the dust removal plate 220 is hinged to the front or rear side of the carrier plate 210 through the transmission shaft. A first motor 230 is arranged on the carrier plate 210, and the first motor 230 is transmission-connected to the transmission shaft.

[0034] During implementation, the front edge or rear edge of the carrier plate 210 is the front edge or rear edge of the carrier plate 210 in the moving direction in the pipeline body 100; the rotating shaft of the first motor 230 is coaxially connected with the transmission shaft.

[0035] In this way, the dust removal plate 220 can be folded onto the carrier plate 210 through the provided transmission shaft, and when there is no need to clean the inner wall of the pipeline body 100, no significant obstruction is formed to the airflow in the pipeline body 100.

[0036] During implementation, a single chip microcomputer is disposed on the carrier board 210 , and the single chip microcomputer can control the start and stop of the first motor 230 .

[0037] In this embodiment, Figure 2-Figure 5 As shown, a first wheel body 240 is installed on the bottom surface of the carrier plate 210 . The first wheel body 240 is located between the carrier plate 210 and the track wall 110 and is in rolling contact with the track wall 110 .

[0038] In this way, by providing the first wheel body 240 , the first wheel body 240 can better support the carrier plate 210 , and also reduce the friction force of the carrier plate 210 moving on the inner wall of the pipe body 100 .

[0039] In this embodiment, Figure 2-Figure 6 As shown, the displacement mechanism includes a connecting frame 310, a gear 320 and a second motor 330. A track groove 340 is provided on the track wall 110. The rack 120 is laid in the track groove 340. One end of the connecting frame 310 is connected to the bottom surface of the carrier plate 210. The gear 320 is rotatably connected to the other end of the connecting frame 310. The gear 320 is meshed with the rack 120 shown. The second motor 330 is installed on the connecting frame 310 and is transmission-connected to the gear 320.

[0040] During implementation, the rotating shaft of the second motor 330 is coaxially connected to the gear 320 .

[0041] In this way, by providing the gear 320 and the second motor 330 , the gear 320 can be driven by the second motor 330 to cooperate with the rack 120 to drive the dust removal mechanism to move.

[0042] In this embodiment, Figure 2 and Figure 3 As shown, a motor frame 350 is provided on the connecting frame 310, and the second motor 330 is installed in the motor frame 350. A second wheel body 360 is connected to the top of the motor frame 350, and a boss 370 is provided at the notch of the track groove 340. The second wheel body 360 rolls against the boss 370.

[0043] During implementation, the second wheel body 360 is located between the motor frame 350 and the boss 370 .

[0044] During implementation, the single chip microcomputer on the carrier board 210 can control the start and stop of the second motor 330 .

[0045] In this way, by providing the motor frame 350 and the second wheel body 360 , the second wheel body 360 can limit the gear 320 so that the gear 320 will not be out of engagement with the rack 120 .

[0046] In this embodiment, Figure 2-Figure 5 , Figure 7 As shown, it also includes a charging mechanism, which includes a third motor 410, a threaded shaft 420 and a plug 430. A telescopic cavity is provided on the bottom surface of the carrier plate 210, and the telescopic cavity has an opening facing the track wall 110. The third motor 410 is installed at the bottom of the telescopic cavity, and the threaded shaft 420 is transmission-connected to the third motor 410. The plug 430 is installed in the telescopic cavity, and a threaded transmission cavity is provided at the bottom of the plug 430. The plug 430 is transmission-connected to the threaded shaft 420 through the threaded transmission cavity.

[0047] During implementation, the cross section of the telescopic cavity is rectangular, and the cross section of the plug 430 is also rectangular.

The starting end of the rack 120 is located at the return air outlet of the return air duct. At the same time, the installation position of the power socket can correspond to the plug 430 so that the plug 430 can be inserted into the power socket.

[0049] During implementation, the single chip microcomputer on the carrier board 210 can control the start and stop of the third motor 410 .

[0050] In this way, the electrical components on the carrier board 210 can be charged through the provided charging mechanism to extend the use time.

[0051] In this embodiment, Figure 1 and Figure 3 As shown, an electrostatic adsorption plate 500 is provided on the dust removal plate 220 .

[0052] During implementation, the electrostatic adsorption plate 500 is disposed on the upper plate surface of the dust removal plate 220 .

[0053] In this way, the dust removal plate 220 can further perform electrostatic adsorption and dust removal on the cloth dressing flowing into the return air duct through the electrostatic adsorption plate 500, thereby improving the dust removal effect.

[0054] In this embodiment, Figure 1 and Figure 3 As shown, the dust removal plate 220 is also provided with ventilation holes 600 .

[0055] During implementation, there are a plurality of vent holes 600 , and the plurality of vent holes 600 are penetrated and arranged on the dust removal plate 220 .

[0056] In this way, when the dust removal plate 220 cleans the inner wall of the duct body 100, the vent holes 600 can provide more air flow to the duct body 100, thereby avoiding a reduction in the return air effect during cleaning.
