[0011] As a further embodiment of the filter section of the air conditioning unit in the tobacco factory, the end of the dust baffle away from the movable seat is tilted upward.

[0012] As a further embodiment of the filter section of the air conditioning unit in the tobacco factory, the first connector is installed on the side of the movable seat opposite to the filter module along the Y direction.

[0013] As a further embodiment of the filter section of the air conditioning unit in a tobacco factory, the transmission assembly includes a connecting plate, a transmission plate, and a transmission rod. The housing has mounting holes corresponding to the position of the connecting plate. These mounting holes penetrate the housing along the X direction. The two ends of the mounting holes along the Z direction are adjacent to the edges of the filter module along the Z direction. The connecting plate is located within the mounting holes, and its two ends along the Y direction are slidably engaged with the wall of the mounting holes. One side of the connecting plate along the X direction is connected to the movable seat, and the other side is connected to the transmission plate. The transmission rod is mounted outside the housing and is connected to the output end of the drive unit. The length of the transmission rod extends along the Z direction. The transmission plate is sleeved on the outer circumference of the transmission rod and threadedly connected to it.

[0014] As a further embodiment of the filter section of the air conditioning unit in the tobacco factory, a second connector is also included. The second connector is installed on the connecting plate of one of the sets of the transmission components. The second connector has an inner connector extending into the housing and an outer connector extending out of the housing. The connecting pipe includes a first connecting pipe located inside the housing and a second connecting pipe located outside the housing. The first connector communicates with the inner connector through the first connecting pipe, and the outer connector communicates with the negative pressure mechanism through the second connecting pipe.

[0015] As a further embodiment of the filter section of the air conditioning unit in the tobacco factory, there are multiple first connectors, which are evenly spaced along the X direction; the number of second connectors is the same as the number of first connectors, and multiple second connectors are evenly spaced along the Y direction, with each first connector connected to the inner connector of the second connector through a first connecting pipe.

[0016] The negative pressure mechanism includes multiple vacuum cleaners, each of which is connected to the outer connector of the second connector via a second connecting pipe.

[0017] As a further embodiment of the filter section of the air conditioning unit in the tobacco factory, it also includes a first shielding curtain and a second shielding curtain for covering the mounting hole. The first shielding curtain and the second shielding curtain are retractable. The upper end of the first shielding curtain is connected to the top wall of the mounting hole, and the lower end of the first shielding curtain is connected to the upper end of the connecting plate. The upper end of the second shielding curtain is connected to the lower end of the connecting plate, and the lower end of the second shielding curtain is connected to the bottom wall of the mounting hole.

[0018] As a further solution for the filter section of the air conditioning unit in the tobacco factory, the first and second shielding curtains are foldable structures.

[0019] As a further embodiment of the filter section of the air conditioning unit in the tobacco factory, the drive unit is a motor, and there are two motors. The two motors are installed at intervals along the X direction on the upper end of the housing. The two ends of the movable seat along the X direction are respectively connected to the output end of one of the motors through a set of transmission components.

[0020] Beneficial effects:

[0021] This invention features a brush head, a movable base, and a first connector arranged on one side of the housing facing the filter module. The drive unit can drive the transmission assembly to move the movable base and brush head up and down. The brush head can brush off dust and impurities from the filter module and suck them out of the housing. At the same time, the air conditioning unit does not need to be stopped, which improves working efficiency, reduces energy consumption caused by starting and stopping, and saves energy.

[0022] This invention places a dust baffle plate below the brush head and connects it to the bottom wall of the suction tank. The dust and impurities brushed off fall directly onto the dust baffle plate, thus preventing dust from being stirred up.

[0023] In this invention, when the drive unit drives the transmission rod to rotate, it can drive the transmission plate to move the connecting plate and the moving seat up and down. The connecting plate slides against the wall of the mounting hole, which improves the stability of the connecting plate's up and down movement. Since the two ends of the mounting hole along the Z direction are adjacent to the edge of the filter module along the Z direction, the brush head can cover the entire filter module when it moves up and down, thereby achieving dust removal without dead angles.

[0024] When the drive unit drives the connecting plate to move the movable seat up and down synchronously, the first connector, the first connecting pipe and the second connector also move up and down synchronously, which improves the connection stability between the first connecting pipe and the first and second connectors.

[0025] The telescopic structure of the first and second blind curtains in this invention can adapt to changes in the area above and below the mounting holes on the connecting plate, thereby blocking the area above and below the mounting holes on the connecting plate and preventing air leakage.

[0026] By setting multiple first and second connectors and connecting pipes, the vacuuming effect is improved, and dead corners are avoided. Attached Figure Description

[0040] like Figures 1 to 6 As shown, the filter section of the tobacco factory air conditioning unit in this embodiment includes a housing 100, a filter module 200, a cleaning mechanism 300, and a negative pressure mechanism.

[0041] The filter module 200 is located inside the housing 100, and its two ends along the X direction and its two ends along the Z direction are connected to the inner wall of the housing 100. The cleaning mechanism 300 includes a drive unit 310, a transmission assembly 320, a brush head 330, a movable seat 340, and a first connector 350 installed inside the housing 100. The movable seat 340 extends along the X direction to the inner wall of the housing 100. The two ends of the movable seat 340 along the X direction are connected to the drive unit 310 located outside the housing 100 via a set of transmission assemblies 320. There is a gap between the movable seat 340 and the filter module 200, and the movable seat 340 has a dust suction groove 3. 401, the opening of the suction slot 3401 faces the filter module 200. The brush head 330 is mounted on the side of the movable base 340 facing the filter module 200 in the Y direction and located above the suction slot 3401. The two ends of the brush head 330 extend to the edge of the filter module 200 in the X direction and abut against the filter module 200. The first connector 350 is mounted on the movable base 340 and communicates with the suction slot 3401. The drive unit 310 can drive the movable base 340 to move up and down in the Z direction. The X, Y and Z directions are perpendicular to each other. The negative pressure mechanism (not shown in the figure) is connected to the first connector 350 through a connecting pipe (not shown in the figure).

[0042] In this embodiment, the housing 100 is a section of the filter section of the air conditioning unit in the tobacco factory. When it is necessary to clean the dust on the filter module 200, the negative pressure mechanism is activated, causing the first connector 350 to draw air into the dust collection groove 3401, creating a negative pressure in the dust collection groove 3401. Then, the drive unit 310 drives the moving seat 340 to move the brush head 330 up and down. Since the brush head 330 abuts against the filter module 200, the dust and impurities on the filter module 200 can be brushed off by the brush head 330. The brushed-off dust and impurities are sucked into the dust collection groove 3401 by the negative pressure and then into the first connector 350. Finally, they enter the negative pressure mechanism through the connecting pipe, thereby achieving dust removal. The brush head 330 covers the filter module 200 along the X direction. When the brush head 330 moves up and down, it can perform dust removal on the entire filter module 200, resulting in high dust removal efficiency and more thorough cleaning. During the dust removal process of the filter module 200, the air conditioning unit does not need to be stopped, which improves working efficiency, reduces energy consumption caused by starting and stopping, and saves energy.

[0043] Because the brush head 330 protrudes from the movable base 340 towards the filter module 200, when dust and impurities on the filter module 200 are brushed off, some of the dust and impurities fall directly outside the suction tank 3401, causing dust to be stirred up and seriously polluting the internal environment of the housing 100. To address this issue, the cleaning mechanism 300 of this embodiment also includes a dust baffle 360, such as... Figure 3 , Figure 4 and Figure 6As shown, the dust baffle 360 ​​is located below the brush head 330. The dust baffle 360 ​​is connected to the movable base 340 on the side facing the filter module 200 and is adjacent to the bottom wall of the suction tank 3401. There is a gap between the dust baffle 360 ​​and the filter module 200. By placing the dust baffle 360 ​​below the brush head 330 and connecting it to the bottom wall of the suction tank 3401, some of the dust and impurities brushed off fall directly onto the dust baffle 360, preventing dust from being stirred up.

[0044] Furthermore, the end of the dust baffle 360 ​​away from the movable seat 340 is tilted upward.

[0045] The air conditioning unit will generate a certain amount of vibration during actual operation. This vibration is transmitted to the movable base 340 and the dust baffle 360, causing the movable base 340 and the dust baffle 360 ​​to also vibrate. Dust and impurities on the inclined dust baffle 360 ​​can slide down the dust baffle 360 ​​into the dust collection groove 3401 through vibration, effectively preventing dust from being stirred up.

[0046] Furthermore, the first connector 350 is installed on the side of the movable base 340 away from the filter module 200 along the Y direction, so that the first connector 350 is directly facing the opening of the dust collection groove 3401, thereby improving the dust removal effect.

[0047] Furthermore, the transmission assembly 320 includes a connecting plate 321, a transmission plate 322, and a transmission rod 323. The housing 100 has a mounting hole 1001 at the position corresponding to the connecting plate 321. The mounting hole 1001 penetrates the housing 100 along the X direction. The two ends of the mounting hole 1001 along the Z direction are adjacent to the edge of the filter module 200 along the Z direction. The connecting plate 321 is located inside the mounting hole 1001, and the two ends of the connecting plate 321 along the Y direction are slidably engaged with the hole wall of the mounting hole 1001. One side of the connecting plate 321 along the X direction is connected to the movable seat 340, and the other side is connected to the transmission plate 322. The transmission rod 323 is installed outside the housing 100 and is connected to the output end of the drive unit 310. The length of the transmission rod 323 extends along the Z direction. The transmission plate 322 is sleeved on the outer periphery of the transmission rod 323 and threadedly connected to the transmission rod 323.

[0048] It is understood that the output end of the drive unit 310 is connected to the transmission rod 323 to drive the transmission rod 323 to rotate; the outer periphery of the transmission rod 323 is provided with external threads (not shown in the figure), and the transmission plate 322 is provided with threaded holes in the vertical direction that are threaded to engage with the transmission rod 323; when the drive unit 310 drives the transmission rod 323 to rotate, it can drive the transmission plate 322 to move the connecting plate 321 and the moving seat 340 up and down, and the connecting plate 321 slides against the wall of the mounting hole 1001, which can improve the stability of the up and down movement of the connecting plate 321. Since the two ends of the mounting hole 1001 along the Z direction are adjacent to the edge of the filter module 200 along the Z direction, the brush head 330 can cover the entire filter module 200 when it moves up and down, thereby achieving dust removal without dead angles.

[0049] For example, a sliding groove is provided on each of the two side walls of the mounting hole 1001 along the Y direction, and the length of the sliding groove extends along the Z direction. A slider 324 protrudes from each end of the connecting plate 321 along the X direction. The slider 324 slides with the sliding groove, which can make the up-and-down movement of the connecting plate 321 and the movable seat 340 more stable. A connecting block protrudes from the side of the connecting plate 321 facing the movable seat 340. The movable seat 340 has a connecting hole facing the connecting block. The connecting block is inserted into the connecting hole and can be locked with screws. The specific details are not described further.

[0050] Furthermore, the filter section of the tobacco factory air conditioning unit in this embodiment also includes a second connector 400, which is installed on the connecting plate 321 of one of the transmission components 320, such as... Figure 5 and Figure 6 As shown, the second connector 400 has an inner connector 410 extending into the housing 100 and an outer connector 420 extending out of the housing 100. The connecting pipe includes a first connecting pipe located inside the housing 100 and a second connecting pipe located outside the housing 100. The first connector 350 is connected to the inner connector 410 through the first connecting pipe, and the outer connector 420 is connected to the negative pressure mechanism through the second connecting pipe.

[0051] In this embodiment, the second connector 400 is mounted on the connecting plate 321. The first connector 350 is connected to the inner connector 410 of the second connector 400 via the first connecting pipe, and the outer connector 420 of the second connector 400 is connected to an external negative pressure mechanism via the second connecting pipe. When the driving unit 310 drives the connecting plate 321 to move the moving seat 340 up and down synchronously, the first connector 350, the first connecting pipe, and the second connector 400 move up and down synchronously as well. This structural design can improve the connection stability between the first connecting pipe and the first connector 350 and the second connector 400.

[0052] Both the first connecting pipe and the second connecting pipe are flexible hoses.

[0053] Furthermore, there are multiple first connectors 350, which are evenly spaced along the X direction; the number of second connectors 400 is the same as the number of first connectors 350, which are evenly spaced along the Y direction, and each first connector 350 is connected to the inner connector 410 of the second connector 400 through a first connecting pipe; the negative pressure mechanism includes multiple vacuum cleaners, each of which is connected to the outer connector 420 of the second connector 400 through a second connecting pipe.

[0054] Since the movable seat 340 is relatively long along the X direction, in this embodiment, multiple first connectors 350 are evenly installed on the movable seat 340 at intervals, which will generate a better negative pressure effect in the dust collection groove 3401, resulting in a better dust collection effect and avoiding the formation of unsanitary corners.

[0055] For example, in this embodiment, there are four first connectors 350 and four second connectors 400. Of course, in other embodiments, the number can be adjusted according to the length of the filter module 200 of the filter section, which will not be described in detail here.

[0056] Furthermore, such as Figure 1 and Figure 3 As shown, the filter section of the tobacco factory air conditioning unit in this embodiment also includes a first shielding curtain 500 and a second shielding curtain 600 for blocking the mounting hole 1001. The first shielding curtain 500 and the second shielding curtain 600 are retractable. The upper end of the first shielding curtain 500 is connected to the top wall of the mounting hole 1001, and the lower end of the first shielding curtain 500 is connected to the upper end of the connecting plate 321. The upper end of the second shielding curtain 600 is connected to the lower end of the connecting plate 321, and the lower end of the second shielding curtain 600 is connected to the bottom wall of the mounting hole 1001.

[0057] Before the cleaning mechanism 300 is installed, the housing 100 is in a closed state. After the cleaning mechanism 300 is installed, the area above and below the mounting hole 1001 connected to the inside and outside of the housing 100, which would cause air leakage. In this embodiment, a first shielding curtain 500 is installed between the top wall of the mounting hole 1001 and the connecting plate 321, and a second shielding curtain 600 is installed between the bottom wall of the mounting hole 1001 and the connecting plate 321. When the connecting plate 321 moves up and down, it will cause the first shielding curtain 500 and the second shielding curtain 600 to extend or shorten to adapt to the change in the area of ​​the mounting hole 1001 above and below the connecting plate 321, thereby shielding the area of ​​the mounting hole 1001 above and below the connecting plate 321 and preventing air leakage.

[0058] Furthermore, the first curtain 500 and the second curtain 600 have a folding structure, similar to a folding fan. When the connecting plate 321 moves to its lowest position, the second curtain 600 located below the connecting plate 321 is in a fully folded and retracted state, while the first curtain 500 located above the connecting plate 321 is in a fully extended and expanded state. When the connecting plate 321 moves to its highest position, the first curtain 500 located above the connecting plate 321 is in a fully folded and retracted state, while the second curtain 600 located below the connecting plate 321 is in a fully extended and expanded state.

[0059] To further prevent air leakage in the housing 100, the first and second shielding curtains 500 and 600 extend into the grooves on the sidewall of the mounting hole 1001 at both ends along the Y direction, and there is a gap between them and the bottom of the groove. When the first and second shielding curtains 500 and 600 are fully folded, their width along the X direction is less than the width of the groove.

[0060] Furthermore, in this embodiment, the drive unit 310 is a motor, and there are two motors. The two motors are installed at intervals along the X direction on the upper end of the housing 100. The two ends of the movable base 340 along the X direction are respectively connected to the output end of one motor through a transmission component 320. By using two motors to synchronously drive the movable base 340 to move up and down, the dust removal efficiency of the filter module 200 can be improved.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application, and they should all be covered within the scope of the claims and specification of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
