[0035] As shown in Figure 3 and Figure 4 , in some embodiments, the automatic dust removal device 30 can include a dust removal roller brush 31, a detection mechanism (not shown), a driving mechanism 32, and a transmission mechanism 33. The dust removal roller brush 31 can be arranged to rotate and move simultaneously, which can be used to remove dust on the dust screen 20. The detection mechanism (not shown) can be installed on the inner side of the dust screen 20, which is used to detect the pressure on the inner and outer sides of the dust screen. The driving mechanism 32 is connected with the dust removal roller brush 31 and the detection mechanism (not shown), and drives the dust removal roller brush 31 to rotate when the pressure difference between the inner and outer sides of the dust screen 20 reaches a set value. The transmission mechanism 33 can be used for transmission of the dust removal roller brush 31, which can make the dust removal roller brush 31 move in a direction perpendicular to the axis of the dust removal roller brush while rotating.
[0036] In some embodiments, the dust-removing roller brush 31 can be substantially cylindrical, and the axial direction of the dust-removing roller brush 31 can be perpendicular to the length direction of the grating on the grating plate 40. The dust-removing roller brush 31 can include a roller brush body 311, a first shaft portion 312, and a second shaft portion 313. The roller brush body 311 can be a cylindrical structure with brush hairs. In some embodiments, the roller brush body 311 can be a plastic roller brush. In other embodiments, the roller brush body 311 can not be limited to a plastic roller brush, but can be a stainless steel roller brush. In some embodiments, the first shaft portion 312 and the second shaft portion 313 are arranged at two ends of the roller brush body 311, and the first shaft portion 312 and the second shaft portion 313 can be coaxially arranged with the roller brush body 311.

[0037] In some embodiments, the driving mechanism 32 can be an electric motor, which can rotate forward and reverse. When the motor rotates forward, it can drive the dust-removing roller brush 31 to rotate clockwise, and at the same time, the dust-removing roller brush 31 can move in a first direction. When the motor rotates reversely, it can drive the dust-removing roller brush 31 to rotate counterclockwise, and at the same time, the dust-removing roller brush 31 can move in a second direction. The first direction can be opposite to the second direction, and both the first direction and the second direction can be perpendicular to the axial direction of the dust-removing roller brush 31.
[0038] In some embodiments, the transmission mechanism 33 can include a transmission gear 331 and a transmission rack 332, wherein the transmission gear 331 is arranged at one end of the dust-removing roller brush 31 and can be connected to the second shaft portion 313, in particular, the transmission gear 331 can be mounted at one end of the second shaft portion 313, and in some embodiments, the second shaft portion 313 and the transmission gear 331 can be an integral structure. Of course, it can be understood that in other embodiments, the second shaft portion 313 and the transmission gear 331 can also be a split structure. In some embodiments, the transmission rack 332 can be mounted on the inner side of the dustproof screen 20 and can extend in a direction perpendicular to the axial direction of the dust-removing roller brush 31. The transmission gear 331 can be engaged with the transmission rack 332, and when the driving mechanism 32 drives the dust-removing roller brush 31 to rotate, the rotation of the dust-removing roller brush 31 can drive the transmission gear 331 to move on the transmission rack 332, that is, the dust-removing roller brush 31 can be driven to rotate and move in a direction perpendicular to the axial direction of the dust-removing roller brush 31 at the same time, so that one driving mechanism 31 can drive the dust-removing roller brush 31 to rotate and move at the same time, not only realizing automatic dust removal, but also simplifying the structure and reducing the production cost.
[0039] In some embodiments, a first bearing assembly 34 is arranged between the roller brush body 311 and the driving mechanism 32, and the first bearing assembly 34 can include a first bearing seat 341 and a first bearing 342. The driving mechanism 32 can be mounted on the first bearing seat 341, the first bearing 342 can be sleeved on the first shaft portion 312, and the first bearing seat 341 can be sleeved on the outer periphery of the first bearing 342. By arranging the first bearing assembly 34, the accuracy of the rotation of the roller brush body 311 can be improved.
[0040] In some embodiments, a second bearing assembly 35 is arranged between the roller brush body 311 and the transmission gear 331, and the second bearing assembly 35 can include a second bearing seat 351 and a second bearing 352. The second bearing 352 can be sleeved on the outer periphery of the second shaft portion 313 and located on the side of the transmission gear 331 away from the transmission rack 332. The second bearing seat 351 can be sleeved on the outer periphery of the second bearing 352. By arranging the second bearing assembly 35, the accuracy of the rotation of the roller brush body 311 can be improved.
[0041] In some embodiments, the automatic dust removal device 30 further comprises a guide mechanism 36, which can be used to guide the movement of the dust removal roller brush 31. In some embodiments, the guide mechanism 36 can be two sets, and the two sets of guide mechanisms 36 can be arranged one-to-one corresponding to the two ends of the dust removal roller brush 31. Specifically, the guide mechanism 36 can be arranged one-to-one corresponding to the two ends of the roller brush body 311, and can be installed on the inner side of the dustproof net 20 between the dustproof net 20 and the dust removal roller brush 31. In some embodiments, each guide mechanism 36 can comprise a sliding block 361 and a guide rail 362. The sliding block 361 can be connected with the dust removal roller brush 31. Specifically, the sliding block 361 of one set of guide mechanisms 36 can be connected with the first bearing seat 342, and the two can be connected and fixed by arranging a screw assembly; the sliding block 361 of the other set of guide mechanisms 36 can be connected with the second bearing seat 351, and can be connected and fixed by arranging a screw assembly. The guide rails 362 of the two sets of guide mechanisms 36 can be arranged at intervals, and the interval between the two can be greater than or equal to the length of the roller brush body 311 in the axial direction. Each guide rail 362 can be arranged in parallel with the transmission rack 332. The sliding block 361 can be sleeved on the guide rail 362 and can move along the length direction of the guide rail 362. The dust removal roller brush 31 can be moved through the cooperation of the sliding block 361 and the guide rail 362, so as to improve the smoothness of the movement.
[0042] For example Figure 2 As shown in some embodiments, the automatic dust removal device 30 further comprises a position detection mechanism 37, which can be two sets. The two sets of position detection mechanisms 37 can be arranged at intervals on the two opposite sides of the dust removal roller brush 31, and located in the extension direction of the transmission rack 332, for detecting the position of the dust removal roller brush 31. Specifically, the two sets of position detection mechanisms 37 can be arranged corresponding to the two limit positions of the dust removal roller brush 31 in the moving direction. One set of position detection mechanisms 37 can correspond to one end of the transmission rack 332, and the other set of position detection mechanisms 37 can correspond to the other end of the transmission rack 332. By arranging the position detection mechanism 37, the position of the dust removal roller brush 31 can be easily detected. The driving mechanism 32 can be connected with the position detection mechanism 37. The driving mechanism 32 can change its rotation direction according to the position information of the dust removal roller brush 31 obtained by the position detection mechanism 37, and then drive the dust removal roller brush 31 to change the moving direction.
[0043] In some embodiments, the position detection mechanism 37 can be a conventional limit sensor, which can be inductively arranged with the slider 361. When the limit sensor senses the slider 361, i.e. when the slider 361 touches the limit sensor, the dust removal roller brush 31 can change the moving direction. For example, when the dust removal roller brush 31 moves in the first direction to the slider 362 touching the limit sensor in the first direction, the driving mechanism 32 reverses, the dust removal roller brush 31 moves in the second direction, and when the dust removal roller brush moves in the second direction to the slider 362 touching the limit sensor in the second direction, the driving mechanism 32 reverses, the dust removal roller brush 31 moves in the first direction. Through the position detection mechanism, the dust removal roller brush 31 can move back and forth. The connection between the position detection mechanism 37 and the driving mechanism 32 can be realized by using the prior art.
[0044] In some embodiments, the detection mechanism (not shown) can be a conventional pressure sensor. In some embodiments, the detection mechanism (not shown) can be two, one of which detects the pressure on the outside of the dust screen 20, and the other detects the pressure on the inside of the dust screen 20. In other embodiments, the detection mechanism (not shown) can also be one. The connection between the detection mechanism (not shown) and the driving mechanism 32 can be realized by using the prior art.
[0045] The working principle of the automatic dust removal device 30 is that when the detection mechanism (not shown) detects that the pressure difference between the inside and outside of the dust screen 20 reaches a set value (threshold value), the driving mechanism 32 starts to work. The rotation of the driving mechanism 32 drives the rotation of the dust removal roller brush 31 through the meshing between the transmission gear 331 and the transmission rack 332. At this time, the dust removal roller brush 31 rotates to clean the dust on the dust screen 20. The other end of the dust removal roller brush 31 is meshed with the transmission gear 331 and the transmission rack 332 to realize the horizontal displacement of the dust removal roller brush 31. The dust removal roller brush 31 is provided with a horizontal support through the two guide rails 362 of the two guide mechanisms 36, so that the dust removal roller brush 31 moves orderly along the guide rail 362. When the slider 361 touches the limit sensor, the driving mechanism 32 is reversed. The reversing direction of the driving mechanism 32 is the opposite direction. This is repeated until the dust on the dust screen 20 is removed. The automatic dust removal device 30 can make the dust removal roller brush 31 rotate and move along the guide rail 362, improve the dust removal area of the dust screen 20, and meet the daily use environment without the need for regular inspection and maintenance of the dust screen 20. Automatic dust removal saves manpower maintenance.
[0046] It can be understood that the above embodiment only expresses the preferred embodiment of the utility model, the description is more specific and detailed, but it can not be understood as the limitation of the utility model patent scope; it should be pointed out that for ordinary skilled person in the art, the above technical features can be freely combined without departing from the concept of the utility model, and a number of deformations and improvements can be made, which belong to the protection scope of the utility model; therefore, any equivalent transformation and modification within the scope of the utility model patent claim should belong to the scope of the utility model patent claim.
