In this way, when the first filtering area needs to be cleaned after filtering for a period of time, the filter screen can be moved online (while the fan is continuously working) to use the second filtering area for filtering, thereby realizing online switching of the actual usage area of ​​the filter screen to save time.

[0035] First aspect

[0036] The present disclosure provides a filtering device 10, as shown in Figures 1 to 3 The filtering device 10 can include a guide support 11, a movable support 12, and a driving structure 13. The guide support 11 has a first guide rail 111 and a second guide rail 112 that extend in a first direction and are parallel to each other, and the guide support 11 is provided with a first limiting piece 113 at one end in the first direction. The movable support 12 is movably connected with the first guide rail 111 and the second guide rail 112, so as to be movable in the direction of approaching the first limiting piece 113 along the first guide rail 111 and the second guide rail 112, and the movable support 12 is provided with a plurality of assembly areas 122 for assembling filter screens 121 distributed in the first direction. The driving structure 13 includes a first controller (not shown in the figure), a second controller (not shown in the figure), and a first driving assembly 131. The second controller is arranged on the first limiting piece 113, and the first driving assembly 131 is electrically connected with the first controller and the second controller and is connected with the movable support 12 at one end corresponding to the first limiting piece 113. The first controller is used to control the first driving assembly 131 to start, so as to drive the movable support 12 to move in the direction of approaching the first limiting piece 113, and in the case that the movable support 12 approaches or presses the second controller, the second controller controls the first driving assembly 131 to stop working.

[0037] The filtering device 10 can be arranged at the air inlet 212 of the fan 20, so as to filter the gas entering through the air inlet 212, thereby ensuring the quality of the gas entering a specific area.

[0038] The guide support 11 can at least support the filter screen 121 and guide the online movement of the filter screen 121, so as to reduce the probability of deviation of the filter screen 121 during movement. The first guide rail 111 and the second guide rail 112 both extend in the first direction and are parallel to each other. For example, the first direction is a vertical direction, the first guide rail 111 is on the left, the second guide rail 112 is on the right, and the first guide rail 111 and the second guide rail 112 both extend in the vertical direction to be parallel to each other. For another example, as shown in Figure 2 and Figure 3 The first direction is a horizontal direction (hereinafter taken as an example for description), the first guide rail 111 is on the top, the second guide rail 112 is on the bottom, and the first guide rail 111 and the second guide rail 112 both extend in the horizontal direction to be parallel to each other. The guide support 11 is provided with the first limiting piece 113 at one end in the first direction. The first limiting piece 113 can be arranged on the first guide rail 111, or on the second guide rail 112, or on other structures (such as the first support rod 114 below) of the guide support 11. The first limiting piece 113 can be a block-shaped or sheet-shaped structure.

[0039] The movable support 12 is movably connected with the first guide rail 111 and the second guide rail 112, so as to be movable along the first guide rail 111 and the second guide rail 112 towards the first limiting piece 113, and the movable support 12 is provided with a plurality of assembly areas 122 of the assembly filter screen 121 distributed along the first direction, so that when a certain assembly area 122 (for example, a first filtering area) is in a position corresponding to the air inlet 212 of the fan 20 and has been filtering for a period of time, another assembly area 122 (for example, a second filtering area) can be moved to the position corresponding to the air inlet 212 of the fan 20 by moving the movable support 12 along the first guide rail 111 and the second guide rail 112 towards the first limiting piece 113, so as to realize online switching of the actual use area of the filter screen 121. The connection between the movable support 12 and the first guide rail 111 and the second guide rail 112 can be sliding connection, for example, the first guide rail 111 and the second guide rail 112 are respectively provided with sliding grooves extending along the first direction, the upper and lower ends of the movable support 12 are respectively located in the sliding grooves of the first guide rail 111 and the second guide rail 112, and can slide along the sliding grooves of the first guide rail 111 and the second guide rail 112 towards the first limiting piece 113, so as to move the movable support 12 towards the first limiting piece 113; or rolling connection, for example, the first guide rail 111 and the second guide rail 112 are respectively provided with strip-shaped grooves extending along the first direction, and the rollers at the upper and lower ends of the movable support 12 are respectively located in the strip-shaped grooves of the first guide rail 111 and the second guide rail 112, and can roll along the strip-shaped grooves of the first guide rail 111 and the second guide rail 112 towards the first limiting piece 113, so as to move the movable support 12 towards the first limiting piece 113.

[0040] The driving structure 13 is used at least to provide driving force to drive the movable bracket 12 to move along the first guide rail 111 and the second guide rail 112 towards the first limiting member 113. The first controller can be arranged on the first driving assembly 131 so that the worker can approach the first driving assembly 131 to operate the first controller; or the first controller can be arranged independently of the first driving assembly 131 and electrically connected to the first driving assembly 131 so that the worker can remotely operate the first controller; or the first controller can be arranged in other manners. The first controller can be a physical switch, a touch switch or other forms of switch arrangement. The worker can control the first driving assembly 131 to start by operating the first controller, thereby driving the movable bracket 12 to move along the first guide rail 111 and the second guide rail 112 towards the first limiting member 113; the worker can also control the first driving assembly 131 to stop by operating the first controller, thereby stopping the movable bracket 12 from moving; and when the movable bracket 12 approaches or presses the first limiting member 113 (the movable bracket 12 is at the first target position), it indicates that the movable bracket 12 will be mispositioned at the air inlet 212 of the fan 20 if it continues to move. Therefore, when the movable bracket 12 approaches or presses the first limiting member 113, the second controller on the first limiting member 113 is triggered to control the first driving assembly 131 to stop, thereby allowing the movable bracket 12 to stop at the first target position in time.

[0041] In an example, referring to Figures 1 to 3 The fan 20 can include an air duct 21 and the filter device 10. The air duct 21 is provided with an air inlet passage 211, and one end of the air inlet passage 211 is an air inlet 212. The filter device 10 is arranged at the air inlet 212 of the air duct 21. The filter device 10 can include a guide bracket 11, a movable bracket 12 and a driving structure 13. The guide bracket 11 has a first guide rail 111 and a second guide rail 112 which extend in the horizontal direction and are parallel to each other. The first guide rail 111 is above the second guide rail 112, and the left end of the first guide rail 111 is provided with a first limiting member 113. The movable bracket 12 is rollingly connected to the first guide rail 111 and the second guide rail 112, so as to be movable along the first guide rail 111 and the second guide rail 112 towards the first limiting member 113. The movable bracket 12 is provided with two assembly areas 122 for assembling filter screens 121 which are distributed in the first direction. One assembly area 122 is opposite to the air inlet passage 211 (as shown in Figure 2The assembly area 122 showing the grid shown in the figure is opposite to the air inlet channel 211); the drive structure 13 includes: a first controller, a second controller and a first drive component 131, the first controller is arranged on the first drive component 131, and the first controller is a physical button, the second controller is arranged on the first limiter 113 and is a physical button, the first drive component 131 is electrically connected to the first controller and the second controller, and is connected to one end of the movable bracket 12 corresponding to the first limiter 113; the first controller is used to control the start of the first drive component 131 to drive the movable bracket 12 to move in the direction close to the first limiter 113, and when the movable bracket 12 squeezes the second controller, the second controller controls the first drive component 131 to stop working. After the fan 20 has been working for a period of time and the fan 20 continues to work, the following operations can be performed to replace the filtering area of ​​the filter 121:

[0042] S101: A staff member operates the first controller to start the first driving assembly 131 to drive the movable bracket 12 to move leftward to approach the first limiting member 113;

[0043] S102: The staff determines based on experience that the other assembly area 122 is opposite to the air inlet channel 211, and then operates the first controller to stop the first drive component 131 from working; or, the movable bracket 12 squeezes the second controller to trigger the second controller, so that the second controller sends a stop-working instruction to the first drive component 131, so that the first drive component 131 stops working.

[0044] In this embodiment, the filter device 10 may include: a guide bracket 11, a movable bracket 12 and a drive structure 13. The drive structure 13 can drive the movable bracket 12 to move relative to the first guide rail 111 and the second guide rail 112 of the guide bracket 11, so that during the movement, different assembly areas 122 of the movable bracket 12 where the filter 121 is assembled correspond to the positions of the air inlet 212 of the fan 20, thereby achieving online switching of the actual use area of ​​the filter 121 to save time. In addition, when the movable bracket 12 moves to the first target position, the first drive component 131 can be automatically controlled to stop working by the second controller to reduce the loss caused by the first drive component 131 not stopping in time.

[0045] In some embodiments, the second controller is a proximity switch, and when the movable bracket 12 approaches the second controller, the second controller controls the first drive component 131 to stop working; or, the second controller is a physical button, and when the movable bracket 12 squeezes the second controller, the second controller controls the first drive component 131 to stop working.

[0046] A proximity switch is a non-contact detection device that can detect whether a target object is within a detection range without directly contacting the target object (such as the movable bracket 12), and control the disconnection of the circuit (such as controlling the disconnection of the first drive component 131 circuit) when detecting that it is within the detection range. For example, when the movable bracket 12 is close to the second controller and is within the detection range of the second controller but is not in contact with the second controller, the second controller controls the disconnection of the circuit of the first drive component 131 to stop the first drive component 131 from working; it can be an inductive proximity switch, a capacitive proximity switch, a photoelectric proximity switch, an ultrasonic proximity switch, a magnetic proximity switch, etc.

[0047] The physical button is a contact-type control structure that can control the disconnection of a circuit (e.g., the first drive assembly 131) when it directly contacts and compresses a target object (e.g., the movable bracket 12). It can be a press-type physical button, etc. It is understood that if the second controller is a physical button, the physical button can be provided on the surface of the first stopper 113 opposite the movable bracket 12, so that when the movable bracket 12 approaches the first stopper 113, it can directly contact and compress the physical button, thereby disconnecting the circuit of the first drive assembly 131.

[0048] In this embodiment, the second controller can be a proximity switch or a physical button, so that one of them can be flexibly selected for setting.

[0049] In some embodiments, see Figure 2 and Figure 3 As shown, the movable bracket 12 includes: a frame 123, a first movable member (not shown in the figure) and a second movable member 124; the frame 123 is provided with a plurality of assembly areas 122 distributed along the first direction; the first movable member is arranged at one end of the frame 123 and is movably connected to the first guide rail 111; the second movable member 124 is arranged at the other end of the frame 123 and is movably connected to the second guide rail 112; wherein, the end of the frame 123 corresponding to the first limit member 113 is connected to the first driving component 131.

[0050] The frame 123 has multiple assembly areas 122 distributed along a first direction. The multiple assembly areas 122 are used to support the filter 121. In this way, when the frame 123 moves along the first direction or a second direction opposite to the first direction, different assembly areas 122 can be aligned with the air inlet duct 211 of the fan 20. In the frame 123, the multiple assembly areas 122 can be equipped with the same filter 121, that is, the area of ​​the filter 121 is large enough to cover multiple assembly areas 122; multiple assembly areas 122 can also be equipped with one filter 121 for each assembly area 122; multiple assembly areas 122 can also be equipped with multiple filters 121 for each assembly area 122, and each filter 121 has a smaller area so that multiple filters 121 can cover one assembly area 122.

[0051] The first movable part can be a first slider, which slides in cooperation with the first sliding groove of the first guide rail 111 to enable the first movable part to move relative to the first guide rail 111; the first movable part can also be a first roller, which can roll in the first strip groove of the first guide rail 111 to enable the first movable part to move relative to the first guide rail 111; the first movable part can also be other settings.

[0052] The second movable member 124 may be a second slider, which slides in conjunction with the second slide groove of the second guide rail 112 to enable the second movable member 124 to move relative to the second guide rail 112; the second movable member 124 may also be a Figure 2 and Figure 3 The second roller shown in the figure can roll in the second strip groove of the second guide rail 112 to realize the movement of the second movable member 124 relative to the second guide rail 112; the second movable member 124 can also be other settings.

[0053] In this embodiment, the frame 123 supports the filter 121, and the first movable member and the second movable member 124 are respectively connected to the frame 123, and are respectively movably connected to the first guide rail 111 and the second guide rail 112. The movable bracket 12 formed in this way has a simple structure and is convenient for mass production.

[0054] In some embodiments, see Figure 2 and Figure 3As shown, the second guide rail 112 is located below the first guide rail 111; the first movable member is a roller that can roll along the first guide rail 111; and the second movable member 124 is a roller that can roll along the second guide rail 112. Because the second movable member 124 supports the frame 123, the filter 121, and the first movable member, the second movable member 124 has a downward force. Since the second movable member 124 is a roller that can roll along the second guide rail 112, the friction force when the second movable member 124 moves relative to the second guide rail 112 is reduced, thereby facilitating the movement of the movable bracket 12 relative to the guide bracket 11.

[0055] In some embodiments, see Figure 2 and Figure 3 As shown, the assembly area 122 of the frame 123 is divided into multiple rows and columns of sub-assembly areas by multiple rows of cross beams and multiple rows of longitudinal beams, and each sub-assembly area can be detachably connected to the filter screen 121.

[0056] Multiple rows of longitudinal beams and multiple rows of transverse beams can be arranged perpendicular to each other or at an angle to form multiple rows and columns of sub-assembly areas; each sub-assembly area can be detachably connected to the filter 121. In this way, after a certain assembly area 122 of the movable bracket 12 does not correspond to the air inlet 212 (such as: the movement of the movable bracket 12 relative to the guide bracket 11 does not correspond, and the disassembly of the movable bracket 12 relative to the guide bracket 11 does not correspond), the filter 121 in the sub-assembly area that is attached with a large amount of dust and other factors that affect the filtration quality can be replaced, thereby reducing the replacement area of ​​the filter 121, thereby reducing the replacement time and reducing the replacement cost.

[0057] Here, the detachable connection may be a screw connection, a snap connection, or other detachable connection methods, which are not specifically limited here.

[0058] In some embodiments, see Figure 1 and Figure 2 As shown, the first drive assembly 131 is located on the side of the frame 123 corresponding to the first stopper 113. The first drive assembly 131 includes a drum 1311, a motor 1312, and a traction rope 1313. The drum 1311 has a winding space. The motor shaft 1314 of the motor 1312 extends into the winding space. The traction rope 1313 is located in the winding space and wound around the motor shaft 1314. One end of the traction rope 1313 is connected to the side of the frame 123 corresponding to the first drive assembly 131. In this way, when the motor 1312 is operating to rotate the motor shaft 1314, the traction rope 1313 (such as a wire rope) can be wound around the motor shaft 1314, thereby pulling the frame 123 connected to the traction rope 1313 toward the first stopper 113. In this embodiment, the structures of the drum 1311, the motor 1312, and the traction rope 1313 are simple and easy to manufacture.

[0059] Here, the motor 1312 can be started or stopped under the control of the first controller.

[0061] The first support rod 114 and the second support rod 115 can connect the first guide rail 111 and the second guide rail 112 together to support the first guide rail 111 and the second guide rail 112; the first guide wheel 1315 is located in the middle position of the first support rod 114, and the traction rope 1313 is also connected to the middle position of the frame 123 corresponding to the first support rod 114 side. In this way, the force provided by the traction rope 1313 to the frame 123 can smoothly pull the frame 123 toward the first limit member 113 (or in other words, it wants to move toward the first support rod 114) to reduce the probability of the frame 123 tilting and getting stuck in a certain position and being unable to continue moving due to the traction position of the traction rope 1313 being biased toward the middle position in the height direction of the frame 123.

[0062] In some embodiments, see Figure 2 and Figure 3 As shown, a second limit piece 116 is provided at the other end of the guide bracket 11 along the first direction; the movable bracket 12 can move along the first guide rail 111 and the second guide rail 112 in the direction close to the second limit piece 116; the driving structure 13 also includes: a third controller, a fourth controller and a second driving component 132, the fourth controller is provided on the second limit piece 116, the second driving component 132 is electrically connected to the third controller and the fourth controller respectively, and is connected to one end of the movable bracket 12 corresponding to the second limit piece 116; the third controller is used to control the start-up of the second driving component 132 to drive the movable bracket 12 to move in the direction close to the second limit piece 116, and when the movable bracket 12 approaches or squeezes the fourth controller, the fourth controller controls the second driving component 132 to stop working.

[0063] That is, the movable bracket 12 can move along the first guide rail 111 and the second guide rail 112 toward the first limiter 113, or it can move along the first guide rail 111 and the second guide rail 112 toward the second limiter 116. Thus, the movable bracket 12 can be selected for operation based on the actual space on both sides of the fan 20, thereby reducing environmental restrictions on the fan 20. The configuration of the second limiter 116 can refer to the configuration of the first limiter 113, the configuration of the third controller can refer to the configuration of the first controller, the configuration of the fourth controller can refer to the configuration of the second controller, and the configuration of the second drive assembly 132 can refer to the configuration of the first drive assembly 131, and no further details will be given here.

In this way, the filter device 10 has a symmetrical and beautiful visual effect.

[0065] It should be noted that when the traction rope 1313 of the first drive component 131 pulls the frame 123 to move toward the first limit member 113, the traction rope of the second drive component 132 can be released along with the movement of the frame 123; on the contrary, when the traction rope of the second drive component 132 pulls the frame 123 to move toward the second limit member 116, the traction rope 1313 of the first drive component 131 can be released along with the movement of the frame 123.
