Description

Technical Field

[0001] The present disclosure relates to a filter support mechanism, a filter support device, and a filter device including the filter support mechanism. Background Art

[0002] Drives are often exposed to complex operating environments and excessive amounts of dust and lint in the air. Once these dust and lint enter the drive, proper operation is affected. Installing a filter at the drive's air inlet can help address these issues. Periodic filter replacement is necessary to address the uneven airflow caused by dust and lint clogging the mesh. Currently, filter replacement is inconvenient. Summary of the Invention

[0003] An object of the present disclosure is to provide a filter support mechanism that facilitates filter replacement.

[0004] Another object of the present disclosure is to provide a filter supporting device that facilitates filter replacement.

[0005] Yet another object of the present disclosure is to provide a filter device that facilitates filter replacement.

[0006] Some specific embodiments of the present disclosure provide a filter support mechanism, which is mounted on a main body and configured to support a filter. The main body has a first opening. The filter is configured to filter the fluid flowing through the first opening. The filter support mechanism includes a first roller, a second roller and a press-on part. The first roller is configured to rotate relative to the main body around its axis. The second roller is configured to rotate relative to the main body around its axis, and the axis of the second roller is parallel to the axis of the first roller. The first roller is configured to wind one end of the filter, and the second roller is configured to wind the other end of the filter. The installation position of the first roller and the second roller is defined so that the portion of the filter between the first roller and the second roller covers the first opening. The press-on part is configured to be movable relative to the main body. The press-on part is movable to clamp the filter to the main body, and the clamped portion of the filter is in an annular shape surrounding the first opening.

[0007] The filter support mechanism unwinds and winds the filter by rotating the first and second rollers. This allows the portion of the filter opposite the first opening to be replaced, making filter replacement convenient. Furthermore, the configuration of the press-fit component allows the filter to be clamped between the press-fit component and the main body. This prevents poor filtration during filtration due to gaps between the filter and the main body caused by filter deformation.

[0008] In one exemplary embodiment of the filter support mechanism, the main body comprises an annular surface surrounding the first opening. The axis of the first roller is parallel to the annular surface. The pressing component includes a cover portion. The cover portion is plate-shaped. The pressing component can be moved to the cover portion to clamp the filter and the annular surface in a mutually parallel position. This simple structure achieves a better pressing effect.

[0009] In another exemplary embodiment of the filter support mechanism, the cover plate portion is in the shape of a mesh plate. In this way, it is beneficial to protect the filter.

[0010] In another exemplary embodiment of the filter support mechanism, the press-fit component further includes a flap portion. The flap portion extends from an edge of the cover portion in a direction perpendicular to the cover portion. When the cover portion clamps the filter against the annular surface, the flap portion can interact with the main body to limit movement of the press-fit component relative to the main body in a direction parallel to the cover portion. This helps improve the stability of the mechanism during use.

[0011] In another exemplary embodiment of the filter support mechanism, the pressing component is configured to be movable relative to the main body in a first direction and a direction opposite to the first direction, wherein the first direction is perpendicular to a plane in which the axes of the first roller and the second roller lie. The filter support mechanism further includes a gear. The gear is configured to rotate relative to the main body about its axis. The pressing component further includes a rack portion. The gear and the rack portion mesh with each other so that the pressing component can be driven to move in the first direction and a direction opposite to the first direction by rotation of the gear. In this way, the pressing component is driven to move linearly by means of a rotational torque.

[0012] In another exemplary embodiment of the filter support mechanism, the filter support mechanism further includes a first drive motor and a control unit. The first drive motor is capable of driving the gear to rotate. The control unit is connected to the first drive motor to control the operation of the first drive motor. This facilitates automatic operation of the mechanism.

[0013] In another exemplary embodiment of the filter support mechanism, the filter support mechanism includes four gears. Every two of the gears form a support unit. The two gears of each of the support units are arranged along a second direction, wherein the second direction is perpendicular to the first direction. The two support units are arranged along a direction perpendicular to the first direction and the second direction. The pressing component includes four rack portions. One of the rack portions is engaged with one of the gears. The two gears of each of the support units are placed on opposite sides or opposite sides of the two rack portions engaged therewith along the second direction to prevent the pressing component from moving relative to the main body along the second direction or in a direction opposite to the second direction. In this way, the entire structure is more compact.

[0014] In another exemplary embodiment of the filter support mechanism, the filter support mechanism further includes a second drive motor and a control unit. The second drive motor is capable of rotating the second roller. The control unit is connected to the second drive motor to control the operation of the second drive motor. This facilitates automatic operation of the mechanism.

[0015] In another exemplary embodiment of the filter support mechanism, the filter support mechanism further includes a transmission mechanism. The transmission mechanism is connected to the second drive motor and the second roller. The second drive motor can drive the second roller to rotate via the transmission mechanism. The transmission mechanism is configured as a synchronous belt drive or a chain drive. This configuration of the transmission mechanism facilitates torque adjustment and spatial arrangement.

[0016] In another exemplary embodiment of the filter support mechanism, the filter support mechanism further includes a damper. The damper acts on the first roller to increase resistance to the first roller's rotation in the direction of unwinding the filter. This facilitates tensioning the portion of the filter between the first and second rollers.

[0017] In another exemplary embodiment of the filter support mechanism, the damper is a damping spindle. This structure has better stability.

[0018] In another exemplary embodiment of the filter support mechanism, the damper is a spring, wherein the spring applies a rotational torque to the first roller through elastic deformation to tension the portion of the filter between the first roller and the second roller. This structure is simple and helps reduce costs.

[0019] Some specific embodiments of the present disclosure further provide a filter support device. The filter support device includes a main body and a filter support mechanism as described above. The main body has a first opening. The filter support mechanism is mounted on the main body and is configured to support a filter configured to filter a fluid flowing through the first opening. The first roller is configured to rotate relative to the main body about its axis. The second roller is configured to rotate relative to the main body about its axis. The first roller is configured to wrap around one end of the filter, and the second roller is configured to wrap around the other end of the filter. The mounting positions of the first and second rollers are defined so that the portion of the filter between the first and second rollers covers the first opening. A pressing component is configured to be movable relative to the main body. The pressing component is movable to clamp the filter to the main body, and the clamped portion of the filter is annular in shape surrounding the first opening. The filter support device facilitates filter replacement. Furthermore, the configuration of the pressing component allows the filter to be clamped between the pressing component and the main body. In this way, during filtration, poor filtering performance caused by gaps between the filter and the main body due to deformation of the filter is avoided.

[0020] Some specific embodiments of the present disclosure further provide a filter device. The filter device includes a main body, a filter, and a filter support mechanism as described above. The main body has a first opening. The filter is configured to filter a fluid flowing through the first opening. The filter support mechanism is mounted on the main body and configured to support the filter. The first roller is configured to rotate relative to the main body about its axis. The second roller is configured to rotate relative to the main body about its axis. One end of the filter is wound on the first roller, and the other end of the filter is wound on the second roller. The portion of the filter between the first roller and the second roller covers the first opening. The pressing component is configured to be movable relative to the main body. The pressing component is movable to clamp the filter to the main body, and the clamped portion of the filter is annular in shape surrounding the first opening. The filter device allows for convenient filter replacement. In addition, the configuration of the pressing component allows the filter to be clamped between the pressing component and the main body. In this way, during filtration, poor filtering results caused by gaps between the filter and the main body due to deformation of the filter are avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] In order to more clearly describe the technical features, objectives and technical effects of the present disclosure, specific embodiments of the present disclosure are described below with reference to the accompanying drawings. In the drawings, the same reference numerals represent elements with the same structure or similar structures but the same functions.

[0055] In this text, the terms "exemplary" or "illustrative" are used herein to mean "serving as an example, instance, or illustration," and any illustration or embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other illustrations or embodiments.

[0056] In this text, the terms "first," "second," etc. do not indicate degree of importance or sequence, but are used merely for distinction and ease of description.

[0057] For the sake of simplicity, only components related to the present disclosure are shown in the drawings, and these components do not represent the actual structure of the product.

[0058] Figure 1 is a schematic structural view of a filter supporting mechanism according to an exemplary embodiment of the present disclosure. Figure 2 Yes Figure 1 An exploded view of the filter support mechanism is shown in FIG. Figure 1 As shown in FIG, the filter support mechanism 100 is mounted on the main body 200 and is configured to support the filter 300. Figure 2 As shown in FIG, the main body 200 is provided with a first opening 201. The filter 300 is configured to filter the fluid flowing through the first opening 201.

[0059] like Figure 1 and Figure 2 As shown in FIG, the filter support mechanism 100 includes a first roller 10 , a second roller 20 and a pressing member 30 .

[0060] The first roller 10 is configured to be rotatable about its axis relative to the main body 200. The second roller 20 is configured to be rotatable about its axis relative to the main body 200, and the axis of the second roller 20 is parallel to the axis of the first roller 10. In this exemplary embodiment, Figure 1 and Figure 2As shown in , both the axis of the first roller 10 and the axis of the second roller 20 are parallel to the third direction D3. The first roller 10 is configured to be wound around one end of the filter 300, and the second roller 20 is configured to be wound around the other end of the filter 300. The installation positions of the first roller 10 and the second roller 20 are defined so that the portion of the filter 300 between the first roller 10 and the second roller 20 covers the first opening 201. Specifically, as shown in Figure 1 and Figure 2 As shown in FIG, the first roller 10 and the second roller 20 are respectively disposed on both sides of the first opening 201 along the second direction D2.

[0061] The pressing member 30 is configured to be movable relative to the main body 200. Specifically, in this exemplary embodiment, the pressing member 30 is configured to be movable relative to the main body 200 along a first direction D1 and a direction opposite to the first direction D1, wherein the first direction D1 is perpendicular to the plane in which the axis of the first roller 10 and the axis of the second roller 20 are located, which is not limited herein.

[0062] Figure 3 Yes Figure 1 Schematic partial structural view of the filter support mechanism shown in FIG. Figure 3 As shown in FIG, in this exemplary embodiment, the filter support mechanism 100 further includes four gears 41. Each of the gears 41 is configured to rotate about its axis relative to the main body 200. Every two of the gears 41 form a support unit 40. The two gears 41 in each support unit 40 are arranged along the second direction D2. The two support units 40 are arranged along a third direction D3 that is perpendicular to the first direction D1 and the second direction D2.

[0063] Figure 4 Yes Figure 1 Schematic structural view of the press-fit parts of the filter support mechanism shown in FIG. Figure 4 As shown in FIG, in this exemplary embodiment, the pressing member 30 includes four rack portions 33. Figure 1As shown in FIG, one of the rack portions 33 is engaged with one of the gears 41, so that the pressing component 30 is driven to move in the first direction D1 and in the direction opposite to the first direction D1 by the rotation of the gear 41. The two gears 41 of each of the support units 40 are arranged on opposite sides of the two rack portions 33 engaged therewith along the second direction D2 to prevent the pressing component 30 from moving in the second direction D2 or in the direction opposite to the second direction D2 relative to the main body 200. In other exemplary embodiments, the two gears 41 of each of the support units 40 may also be arranged on opposite sides of the two rack portions 33 engaged therewith along the second direction D2. In this way, the pressing component 30 can also be prevented from moving in the second direction D2 or in the direction opposite to the second direction D2 relative to the main body 200.

[0064] In this exemplary embodiment, the pressing component 30 is movably connected to the main body 200 via four gears 41 and four rack portions 33, but the present invention is not limited thereto. In other exemplary embodiments, the pressing component 30 may be movably connected to the main body 200 via other structures. These structures include, but are not limited to, rail structures. Based on this, by configuring the gears 41 and rack portions 33, the rotation of the gears 41 drives the pressing component 30 to move. However, in other exemplary embodiments, the pressing component 30 may be driven to move via other structures.

[0065] The pressing member 30 is movable to clamp the filter to the main body 200, and the clamped portion of the filter 300 is in an annular shape surrounding the first opening 201. Specifically, in this exemplary embodiment, as shown in FIG. Figure 2 As shown in FIG, the main body 200 has an annular surface 202 surrounding the first opening 201. The axis of the first roller 10 is parallel to the annular surface 202. The pressing member 30 includes a cover portion 31. The cover portion 31 is plate-shaped. The pressing member 300 can be moved to the cover portion 31 to clamp the filter 300 and the annular surface 202 in a mutually parallel position. In this way, the annular portion of the filter 300 opposite the annular surface 202 is clamped and secured by the cover 31 and the main body 200. Figure 1 The filter 300 is shown in a clamped state.

[0066] A structure that allows fluid to flow through is placed at the center of the cover portion 31. Figure 1 、 Figure 2 and Figure 4 As shown in FIG, in this exemplary embodiment, the cover portion 31 is in the shape of a mesh plate and is provided with a plurality of grids 311, so that the filter 300 is protected, but the invention is not limited thereto. In other exemplary embodiments, the cover portion 31 may also be a large hole opened in the center.

[0067] Using the filter support mechanism, the filter can be replaced, for example, as follows: First, the pressing member 30 is moved to separate from the position of the filter 300. Subsequently, the first roller 10 and the second roller 20 are rotated to replace the portion of the filter 300 that is opposite the first opening 201. When the replacement is completed, the pressing member 30 is moved back to the position where the pressing member clamps the filter 300 and the body 200.

[0068] During use, the filter support mechanism unwinds and rewinds the filter 300 by rotating the first roller 10 and the second roller 20. Through these operations, the portion of the filter 300 that faces the first opening 201 can be replaced. In this manner, the filter 300 can be conveniently replaced. It should be noted that "replacing the filter" herein refers to replacing the portion of the filter that faces the first opening, rather than removing the entire filter from the filter support mechanism and loading another filter into the filter support mechanism.

[0069] In addition, by configuring the compression member 39, the filter 300 can be clamped between the compression member 39 and the body 200. In this way, during filtration, poor filtering effects due to gaps between the filter 300 and the body 200 caused by deformation of the filter 300 are avoided.

[0070] like Figure 1 、 Figure 2 and Figure 4 As shown in FIG, in this exemplary embodiment, the press-fitting member 30 further includes a flap portion 32. The flap portion 32 extends from the edge of the cover portion 31 in a direction perpendicular to the cover portion 31. In this exemplary embodiment, the flap portion 32 is annular in shape, surrounding the cover portion 31, but is not limited thereto. When the cover portion 31 clamps the filter 300 against the annular surface 202, the flap portion 32 can interact with the main body 200 to limit movement of the press-fitting member 30 relative to the main body 200 in a direction parallel to the cover portion 31. This helps improve the stability of the mechanism during use.

[0071] like Figures 1 to 3 As shown in FIG, in this exemplary embodiment, the filter support mechanism 100 further includes four first drive motors 50. Each of the first drive motors 50 can drive one of the gears 41 to rotate. This facilitates operation, but the present invention is not limited thereto. In other exemplary embodiments, the first drive motors 50 may not be provided, and the gears 41 may be driven to rotate manually.

[0072] like Figures 1 to 3As shown in FIG, in this exemplary embodiment, the filter support mechanism 100 further includes a second drive motor 60 and a transmission mechanism 70. The transmission mechanism 70 is connected to the second drive motor 60 and the second roller 20. The second drive motor 60 can drive the second roller 20 to rotate via the transmission mechanism 70. In this exemplary embodiment, the transmission mechanism 70 is configured as a synchronous belt drive structure and includes two synchronous pulleys 71 and a synchronous belt 72. The two synchronous pulleys 71 are respectively fixed to the output shaft of the second drive motor 60 and the second roller 20, and the synchronous belt 72 is wrapped around the two synchronous pulleys 71. In other exemplary embodiments, the transmission mechanism 70 can also be configured as another structure that synchronizes the movement between the second drive motor 60 and the second roller 20, including but not limited to a chain drive structure. The configuration of the second drive motor 60 facilitates operation, but is not limited to this. In other exemplary embodiments, the second drive motor 60 may not be provided, and the second roller 20 can be manually driven to rotate. The configuration of the transmission mechanism 70 facilitates torque adjustment and spatial arrangement, but is not limited to this. In other exemplary embodiments, the transmission mechanism 70 may not be provided, and the second roller 20 may be directly driven to rotate by the second driving motor 60 .

[0073] like Figure 1 and Figure 2 As shown in FIG, in an exemplary embodiment, the filter support mechanism 100 further includes a damper 80. The damper 80 acts on the first roller 10 to increase resistance to the rotation of the first roller 10 toward the direction of unfolding the filter 300. This facilitates tensioning of the portion of the filter 300 between the first roller 10 and the second roller 20. Specifically, in the exemplary embodiment, the damper 80 is a damping spindle. In other exemplary embodiments, the damper 80 may also be a spring, wherein the spring elastically deforms to apply a rotational torque to the first roller 10, thereby tensioning the portion of the filter 300 between the first roller 10 and the second roller 20.

[0074] Figure 5 1 is a schematic structural view of a filter support mechanism according to another exemplary embodiment of the present disclosure. The filter support mechanism according to this exemplary embodiment and the filter support mechanism according to the exemplary embodiment will not be further described herein. Figure 1 The common or similar points between the filter support mechanisms shown in FIG and FIG are omitted, and the differences between the two filter support mechanisms are described below. In this exemplary embodiment, the filter support mechanism 100 further includes a control unit 90. The control unit 90 is connected to the first drive motor 50 and the second drive motor 60 to control the operation of the first drive motor 50 and the second drive motor 60. By configuring the control unit 90, the first drive motor 50 and the second drive motor 60 can be automatically operated. For example, by defining a program in the control unit 90, periodic filter replacement can be automatically performed.

The pressing part 30 is movable to clamp the filter to the main body 200, and the clamped portion of the filter 300 is in an annular shape surrounding the first opening 201. The filter support device allows for easy replacement of the filter. It should be noted that "replacing the filter" herein refers to replacing the portion of the filter opposite the first opening, rather than removing the entire filter from the filter support mechanism and loading another filter onto the filter support mechanism. In addition, through the configuration of the pressing part 30, the filter 300 can be clamped between the pressing part 39 and the main body 200. In this way, during filtration, poor filtering effects caused by gaps between the filter 300 and the main body 200 due to deformation of the filter 300 are avoided.
