Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a dust reduction module and cleaning equipment. Background Art

[0002] Some existing cleaning equipment uses fans for dust reduction and control, leveraging the air volume and pressure generated by the fans to effectively draw dust raised by the side and roller brushes into the dustbin. To prevent dust and other particulate matter from entering the fan and causing blockage or even damage, a filter is typically installed at the fan's front air inlet. Over extended use, the filter gradually accumulates and absorbs large amounts of dust, affecting airflow permeability and resulting in poor dust reduction and control effectiveness.

[0043] Please also refer to Figures 1 to 4 One embodiment of the present application provides a dust reduction module 10, which is used to be installed in a cleaning device to reduce the dust generated when the cleaning device is working. The dust reduction module 10 includes a dust reduction fan 500, a filter 200 and a dust removal mechanism 100. The filter 200 is arranged on the air inlet channel of the dust reduction fan 500 to prevent dust from entering the dust reduction fan 500. The dust removal mechanism 100 includes a pull rod 110 and a scraper 120. The pull rod 110 is arranged on one side of the filter 200, and the scraper 120 is arranged on the side of the pull rod 110 close to the filter 200. The pull rod 110 is configured to operably drive the scraper 120 to reciprocate relative to the filter 200 so that the scraper 120 scrapes the filter 200.

[0044] The dust reduction module 10 provided in this embodiment includes a dust removal mechanism 100, which drives the pull rod 110 of the dust removal mechanism 100 to move and drive the scraper 120 to make reciprocating motion relative to the filter 200. The scraper 120 on the pull rod will repeatedly collide and scrape the filter 200, thereby vibrating and shaking off the dust attached to the filter 200, achieving dust removal and cleaning of the filter 200, reducing the accumulation and adsorption of dust on the filter 200, and avoiding affecting the normal operation of the dust reduction fan 600. The operation is convenient and quick, and there is no need to remove the filter 200 to clean the dust.

[0045] Please combine Figure 2 and Figure 3 Furthermore, the dust removal mechanism 100 also includes a scraper 130, which is arranged on the side of the pull rod 110 close to the filter 200. The scraper teeth 120 are protrudingly arranged on the scraper 130 and facing the filter 200. The scraper 130 is arranged on the pull rod 110, and the scraper teeth 120 are arranged on the scraper 130. This design is conducive to replacing the scraper 130 and the scraper teeth 120 as a whole consumable material, because when the dust removal mechanism 100 is working, the scraper teeth 120 will repeatedly collide and scrape the filter 200. Over time, the scraper teeth 120 are bound to be worn and damaged. Preferably, the plurality of scrapers 120 and the scraper 130 are an integrally formed part, and the scraper teeth 120 are formed on the scraper 130. More preferably, the scraper teeth 120 and the scraper 130 of the integrally formed part are selected from flexible material parts such as rubber parts and silicone parts. The use of flexible materials can, on the one hand, reduce the noise generated by the scraper 130 colliding and scraping the filter 200 , and on the other hand, reduce the wear and tear of the scraper teeth 120 and the filter 200 .

[0046] It is understood that the filter 200 is selected from one of the commonly used filter elements such as multi-stage filter, HEPA, filter cotton, etc. Specifically, in this application, the filter adopts HEPA, which is a filter element made of high-efficiency filter material through multiple layers of continuous folding. It mainly includes a frame and a continuous pleated filter material fixed by the frame. Figures 2 to 4 As shown, a plurality of scraping teeth 120 are arranged at intervals on the scraper 130, and a plurality of scraping teeth 120 extend into the recesses of the pleats 210 of the filter 200. Setting the scraping teeth 120 into the recesses of the pleats 210 extending into the filter 200 can enable the scraping teeth 120 to better act on the filter 200, thereby improving the dust vibration and dust removal efficiency of the dust removal mechanism 100. Specifically, the number of scraping teeth 120 can be set to one or more; if a plurality of scraping teeth 120 are provided, the plurality of scraping teeth 120 are evenly distributed at intervals along the extension direction of the pull rod 110 or the scraper 130. Preferably, the moving direction of the scraper 130 is perpendicular to the recessed direction of the pleats of the filter 200, and the protruding direction of the scraping teeth 120 is parallel to the recessed direction of the pleats 210 of the filter 200. For example, in Figure 3In a specific embodiment, the pleats 210 are recessed in the vertical direction, the scraping teeth 120 are protruding in the vertical direction, and the scraper 130 moves in the horizontal direction. When the scraper 130 moves in a direction perpendicular to the recessed direction of the filter 200 pleats, the scraper teeth 120 collide with the pleats more forcefully during the reciprocating motion of the scraper 130, thereby more thoroughly removing dust adhering to the surface of the filter 200 and achieving a better dust removal effect.

[0047] Preferably, the scraping teeth 120 may be shaped like a wedge, a falcon, a strip, a sheet, or the like, which is conducive to penetrating into the recesses of the pleats 210 of the filter 200 .

[0048] Furthermore, the dust removal mechanism 100 also includes a driving member, which is connected to the pull rod 110 and is used to drive the scraping teeth 120 to reciprocate relative to the filter 200. The provision of a driving member connected to the pull rod 110 makes it easier for the operator to drive the scraping teeth 120 through the pull rod 110 to perform a scraping reciprocating motion relative to the filter 200 to achieve a dust-vibrating effect. Figures 1 to 3 In the specific embodiment shown, the driving member is configured as a handle 140. The handle 140 is connected to the other end of the pull rod 110 away from the filter 200, and is partially exposed to the dust reduction module 10. Setting the handle 140 as the driving member has a simple structure and high reliability. The operator only needs to push and pull the handle 140 back and forth to drive the scraping teeth 120 to reciprocate relative to the filter 200 to perform collision and scraping. Further, as Figure 3 As shown, the handle 140 is further provided with a gripping groove 141. The design of the gripping groove 141 facilitates the operator to put his fingers deep into the groove and grip the handle 140, thereby making it more convenient for the operator to apply force to the pull rod 110.

[0049] It is understood that in other embodiments, to save labor, the driving member can also be configured as a linear motor, a cylinder, or other components. In this case, its power output end is connected to the other end of the pull rod 110 relative to the filter 200. Configuring the driving member as an automated component such as a linear motor or a cylinder can save manpower and provide a better user experience.

[0050] Furthermore, the dust removal mechanism 100 may also include a reset assembly. The reset assembly includes a free end and a fixed end. The free end of the reset assembly is connected to the end of the pull rod 110 away from the handle 140, and the other end of the reset assembly is fixed to an environmental element such as a housing. The reset assembly is connected to the pull rod 110, and the reset assembly is configured to drive the pull rod to return to its original position. For example, the reset assembly can be set as an elastic member such as a tension spring, a rubber band, a tension belt, or a magnetic member such as an electromagnet. The reset assembly drives the pull rod to reset through the elastic force or suction of the elastic member. The provision of a reset member can save effort when the user uses manpower to pull the pull rod 110 to drive the scraper 120 to shake the dust.

[0051] In some embodiments, when the reset assembly is configured as an elastic member, one end of the elastic member is connected to the end of the pull rod 110 or the scraper 130 away from the handle 140, and the other end is fixedly connected to an environmental element such as a housing. When the driving member pulls the pull rod 110 or the scraper 130 to move forward, the elastic member undergoes tensile or compressive deformation, and then the elastic member automatically resets by pulling the pull rod 110 or the scraper 130 in the reverse direction. In this way, the reciprocating motion of the pull rod 110 or the scraper 130 drives the scraping teeth 120 to collide and scrape the folds of the filter 200, thereby achieving a better dust-vibrating effect. Furthermore, the elastic member can be mounted on a guide rod to facilitate the guiding and limiting of the pull rod 110 or the scraper 130, preventing it from tilting during reciprocating motion and tearing the filter 200.

[0052] Furthermore, in some preferred embodiments, the dust removal mechanism 100 can be installed on both sides of the filter 200. The scraping teeth 120 of the dust removal mechanism 100 on the upper side of the filter 200 are inserted from the upper side into the pleated recesses of the upper opening. Similarly, the scraping teeth 120 of the dust removal mechanism 100 on the lower side of the filter 200 are inserted from the lower side into the pleated recesses of the lower opening. Providing a set of dust removal mechanisms 100 on both the upper and lower sides of the filter 200 can enhance the collision and scraping of the filter 200 pleats, thereby achieving a better dust vibration cleaning effect.

[0053] See Figure 5 In some embodiments, the dust reduction module 10 further includes a housing 300 and a quick-release mechanism 400, and the filter 200 is detachably installed in the housing 300 through the quick-release mechanism 400. In this way, the user can easily remove the filter 200 for maintenance or replacement. Figure 5 and Figure 6 As shown, in some embodiments, the housing 300 includes a housing body 330 and a flip plate 310 for carrying the filter 200. The housing body 330 is provided with a receiving slot, and the flip plate 310 is rotatably connected to the housing body 330 to close or open the receiving slot.

[0054] In some embodiments, the quick release mechanism 400 includes a snap-fit member and a slot. One of the flip plate 310 and the shell body 330 is provided with a snap-fit member, and the other is provided with a slot. When the flip plate 310 rotates to the closed receiving slot, the snap-fit member is snapped into the slot.

[0055] Specifically, a receiving slot is defined at the bottom of the housing 300, and a flip plate 310 is pivotally connected to either side of the housing body 330 near the receiving slot. When the flip plate 310 is pivoted upward, it gradually closes the receiving slot on the housing 300. Conversely, when the flip plate 310 is pivoted downward, the opening of the receiving slot in the housing body 330 opens. The filter 200 can be placed on the flip plate 310 and then installed in the receiving slot on the housing body 330 by pivoting the flip plate 310 upward. When the flip plate 310 is pivoted to close the housing receiving slot, the snap-fit member 410 snaps into the snap-fitting slot 421, thereby securing the flip plate 310 and the housing body 330 together through a snap-fit connection. This in turn secures the filter 200 within the housing 300, completing its installation. When the filter 200 needs to be removed, it is only necessary to release the snap-fitting relationship between the flip plate 310 and the shell body 330 , and then the flip plate 310 and the filter 200 will automatically flip downward under the action of their own gravity, so that the filter 200 can be pulled out.

[0056] Furthermore, when installing the filter 200, place it on the top edge of the flip plate 310, and then push the flip plate 310 to slide it completely onto the flip plate 310. Conversely, when removing the filter 200, after the flip plate 310 is flipped downward into place, pull the filter 200 to slide it out of the flip plate 310.

[0057] See Figures 6 to 8 In some embodiments, the clamping member 410 is provided on the flip plate 310, and the clamping slot 421 is provided on the housing body 330. Alternatively, in other embodiments, the positions of the clamping member 410 and the clamping slot 421 may be interchanged.

[0058] Please refer to Figures 8 to 11 In some embodiments, the quick release mechanism 400 includes a locking member 420, a first elastic member 430 and a limiting member 440, the card slot 421 is opened in the locking member 420, the first elastic member 430 is connected between the locking member 420 and the shell body 330, and the limiting member 440 is connected to the shell body 330; the locking member 420 is rotatably connected to the shell body 330 to switch between the unlocked position and the locked position; the locking member 420 can rotate under the abutment of the clamping member 410 to reach the locked position, and the limiting member 440 can limit the locking member 420 to the locked position; after the limiting member 440 releases the limit on the locking member 420, the first elastic member 430 is used to drive the locking member 420 to rotate toward the unlocked position.

[0059] Specifically, the quick-release mechanism 400 includes a first plate 471 and a second plate 472 spaced apart, at least one of which is fixed to the housing body 330. A first column 473, a second column 474, and a third column 475 are disposed between the first and second plates 471 and 472, each fixedly connected to the other. A locking member 420 is sleeved around the second column 474 and can rotate about it. When the locking member 420 is rotated to the unlocked position, the slot 421 tilts downward, allowing the engaging member 410 to engage or disengage from the slot 421. When the locking member 420 is rotated to the locked position, the slot 421 faces horizontally, preventing the engaging member 410 from disengaging, ensuring a stable engagement. The first elastic member 430 is a torsion spring sleeved around the second column 474, with one end abutting the second plate 472 and the other end abutting the locking member 420. The torsion spring's rebound force causes the locking member 420 to rotate from the locked position to the unlocked position. Therefore, when the locking member 420 reaches the locking position, it needs to be limited by the limiting member 440 to overcome the rebound force of the torsion spring so that the locking member 420 remains in the locking position.

[0060] To install the filter 200, simply place the filter 200 on the flip plate 310 and push it upward. The engaging member 410 engages the slot 421 and contacts the wall of the slot 421, thereby rotating the locking member 420 toward the locked position. During this process, the torsion spring deforms and compresses. To remove the filter 200, the retaining member 440 releases the retaining member 420. Under the rebound force of the torsion spring, the locking member 420 rotates from the locked position to the unlocked position. Under the weight of the flip plate 310 and filter 200, the engaging member 410 disengages the slot 421, releasing the engagement between the two.

[0061] Please refer to Figure 7 and Figure 9 In some embodiments, the limit member 440 is rotatably connected to the shell body 330, and a second elastic member 450 is connected between the limit member 440 and the shell body 330; when the locking member 420 is in the locked position, the limit member 440 can be rotated under the drive of the second elastic member 450 until it is engaged with the locking member 420; the limit member 440 is configured to be operably rotated to separate from the locking member 420, and the first elastic member 430 drives the locking member 420 to rotate to the unlocked position.

[0062] Please also refer to Figure 10Specifically, the limiting member 440 is sleeved on the third column 475 and can rotate around the third column 475. The second elastic member 450 is a torsion spring, which is sleeved on the third column 475, with one end abutting the second column 474 and the other end abutting the limiting member 440. When the locking member 420 is in the locked position, the rebound force of the torsion spring (the second elastic member 450) drives the limiting member 440 to rotate until it engages with the locking member 420, thereby limiting the locking member 420 in the locked position to prevent it from being unlocked under the rebound force of the first elastic member 430. When the user operates the limiting member 440 to rotate and separate from the locking member 420, releasing the engagement between the two, the locking member 420 rotates to the unlocked position under the rebound force of the first elastic member 430.

[0063] Please continue reading Figure 10 In some embodiments, the limiting member 440 includes a convex limiting block 441, and the locking member 420 includes a concave limiting groove 422. The limiting block 441 engages with the limiting groove 422 to lock the locking member 420 in the locked position. In other embodiments, other common locking structures may be used. Alternatively, the limiting member 440 may abut against the locking member 420 to limit the locking member 420.

[0064] Please also refer to Figure 11 Specifically, when the locking member 420 is in the unlocked position, the limiting block 441, driven by the rebound force of the second elastic member 450, abuts the side wall of the locking member 420 adjacent to the limiting groove 422. When the filter 200 is installed, when the flip plate 310 is pushed upward, the engaging member 410 engages the engaging groove 421 and abuts the groove wall of the engaging groove 421, driving the locking member 420 to rotate counterclockwise toward the locked position. During the rotation of the locking member 420, the limiting member 440 is pushed by the side wall of the locking member 420 and rotates counterclockwise by a small angle to avoid the locking member 420 and allow the locking member 420 to reach the locked position. When the locking member 420 reaches the locked position, the limiting member 440 rotates clockwise under the rebound force of the second elastic member 450, and the limiting block 441 engages the limiting groove 422, securing the locking member 420 in the locked position.

[0065] Please refer again Figures 6 and 7 In some embodiments, the dust suppression module 10 further includes an unlocking lever 460. The unlocking lever 460 is connected to the limiting member 440. By pulling the unlocking lever 460 upward, the limiting member 440 can be driven to rotate counterclockwise, so that the limiting block 441 is disengaged from the limiting groove 422, thereby releasing the limit on the locking member 420.

[0066] In other embodiments, the unlocking rod 460 can also be movably connected to the flip plate 310 or the shell body 330. By moving the unlocking rod 460 upward or rotating, it abuts against the limiting member 440 and drives the limiting member 440 to rotate, so that the limiting block 441 disengages from the limiting groove 422, thereby releasing the limit on the locking member 420.

[0067] In other embodiments, the limiting member 440 can also limit the locking member 420 in other ways. For example, the limiting member 440 can be driven by a motor or a cylinder. When the locking member 420 reaches the locked position, the motor or cylinder drives the limiting member 440 to engage or abut against the locking member 420, thereby locking the locking member 420 in the locked position. When the filter 200 needs to be removed, the motor or cylinder drives the limiting member 440 to move away from the locking member 420, thereby releasing the locking member 420 from the position.

[0068] Please refer again Figures 7 and 8 In some embodiments, the clamping member 410 includes a core shaft and a protective sleeve disposed on the outside of the core shaft, which is rotatable relative to the core shaft. The protective sleeve snaps into the slot 421 to achieve the connection between the flip plate 310 and the housing body 330. This allows the protective sleeve to rotate relative to the core shaft during assembly and disassembly, reducing wear on the core shaft and extending its service life.

[0069] Please refer again Figure 5 and Figure 7 In some embodiments, the dust suppression module 10 includes two sets of the aforementioned quick-release mechanisms 400, symmetrically positioned at either end of an unlocking lever 460. The retaining members 440 in both sets of quick-release mechanisms 400 are connected to the unlocking lever 460. This allows the flip plate 310 to be securely connected to the housing body 330 via the two sets of quick-release mechanisms 400, resulting in a more secure and stable installation. To disassemble, simply pull the unlocking lever 460 upward, which simultaneously rotates the retaining members 440 in both sets of quick-release mechanisms 400, thereby releasing the retaining members 420 in both sets of quick-release mechanisms 400.
