Description

Technical Field

[0001] The present invention relates to the field of mobile dust removal, in particular to a mobile dust removal device for household services. Background Art

[0002] The equipment commonly used for household dust removal can be divided into two categories: household self-cleaning equipment and professional service tools. The floor is cleaned by cleaning equipment and dust is collected by dust collector. The working principle of the dust collector is usually that the dust-laden gas enters the air inlet of the dust collector, and then the air flow moves upward under the action of the wind shield, the flow rate decreases, and some large particles of dust are separated due to inertia and fall into the ash hopper. The dust-laden gas further flows to the filter bag for purification, and the dust is retained on the outer surface of the filter bag.

[0003] There are at least the following problems that have not been solved in the existing technology: when ordinary households perform dust removal, they need to use the cooperation between the roller brush and the vacuum cleaner to deal with impurities on the ground. During the cleaning process of the roller brush, a large amount of impurities in the roller brush will be stuck in the brush, which will cause the vacuum cleaner to only deal with the dust on the roller brush and the surface of the ground, but cannot absorb the remaining impurities in the roller brush. Summary of the Invention

The dust removal roller brush device also includes a cleaning part for removing impurities on the roller brush, and the cleaning part is transmission-connected to the rotating rod. The sliding frame is provided with an end face processing part at the end of the roller brush.

[0005] Preferably, there are two cleaning members, both of which are rotatably connected to the sliding frame, and the two cleaning members are respectively located at both ends of the roller brush, and the two cleaning members each include a shell fixedly connected to the outer wall of the sliding frame, the rotating rod is fixedly connected to a rotating gear, the sliding frame is rotatably connected to a rotating disk, the outer wall of the rotating disk is provided with an annular gear ring that meshes with the rotating gear, the end surface of the rotating disk is slidably connected to an adjusting plate, the outer shell is slidably connected to a movable frame, a connecting rod is provided between the adjusting plate and the movable frame, and the connecting rod is hingedly connected to the adjusting plate and the movable frame.

[0006] Preferably, a mounting rod is fixedly connected between the two movable frames on the two cleaning parts, and a scraper capable of adjusting the deflection angle is rotatably connected to the mounting rod. The scraper is made of silicone material and extends toward the inside of the roller brush. A movable groove slidably connected to the mounting rod is provided on the outer shell, and a sealing plate is also fixedly connected to the mounting rod, and the sealing plate covers the movable groove.

[0007] Preferably, a control electric cylinder is fixedly connected to the outer wall of the dust suction chamber, the telescopic end of the control electric cylinder is connected to the outer wall of the sliding frame, the axis of the rotating disk is also clamped and connected to the rifle rod, the rotating disk is rotatably connected to the transmission gear, the transmission gear is provided with a sleeve spirally connected to the rifle rod, the adjustment plate is fixedly provided with a rack meshing with the transmission gear, and the rifle rod is also fixedly connected to an external chuck.

[0008] Preferably, an L-shaped groove is provided on the movable bracket, and an oblique groove is provided on the outer wall of the sliding bracket, and the oblique groove is located below the L-shaped groove. A connecting bracket is rotatably connected to the external chuck, and a vertical rod is vertically provided on the connecting bracket. The vertical rod is inserted into the L-shaped groove and the oblique groove, and a pulley is provided on the vertical rod to be slidably connected to the L-shaped groove and the oblique groove.

[0009] Preferably, there are two end face processing parts, which are respectively arranged on the sliding frame and located at both ends of the roller brush. The two end face processing parts each include a convex plate fixedly connected to the inner wall of the sliding frame, the convex plate is rotatably connected to the rotating rod, and the rotating rod is rotatably connected to the deflection frame, one end of the deflection frame is fixedly connected to a clamping rod, a U-shaped groove is provided on the movable frame, and the clamping rod on the deflection frame extends into the U-shaped groove.

[0010] Preferably, the deflection frame is hingedly connected to a resistance frame at one end away from the clamping rod, and a torsion spring is provided between the resistance frame and the deflection frame. A limiting sphere is fixedly connected to the resistance frame, and the limiting sphere abuts against the outer end face of the convex disc under the restriction of the torsion spring, and the limiting sphere can move toward the end face of the roller brush when it contacts the raised end of the convex disc.

[0011] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the mounting rod on the movable frame drives the scraper to extend toward the roller brush. The scraper extending toward the roller brush can clean long hair, fibers and other soft garbage, and the roller brush may be entangled due to continuous involvement. The intermittent action of the scraper can periodically extend toward the scraper to cut or peel off the entanglement on the roller brush, reducing the risk of jamming. The scraper is intermittently extended toward the roller brush to avoid continuous contact between the scraper and the roller brush, which increases mechanical friction resistance, leads to increased energy consumption of the equipment, increased noise and other effects.

[0012] In the present invention, the roller brush is generally divided into surface dust, middle debris and root entanglements during cleaning. The scraper gradually extends to the inside of the roller brush, which can clean the roller brush more thoroughly and remove impurities inside the roller brush in a targeted manner, so that the dust suction chamber can adsorb the impurities inside the roller brush.

[0013] In the present invention, when the moving frame moves a distance that enables the deflection frame to drive the limiting ball to contact the raised end of the convex plate, the limiting ball moves toward the end surface of the roller brush under the restriction of the raised end of the convex plate, and at this time the limiting ball abuts the end surface of the roller brush; The limiting sphere squeezes and forces the brush on the end face of the roller brush to deform. Through mechanical friction and squeezing, dust, hair, debris and other debris embedded in the root of the brush are squeezed out, especially small particles that are difficult to remove with traditional cleaning. At this time, the dust absorption of the dust chamber can effectively remove the impurities remaining in the brush. Dust, hair and other impurities are easily accumulated on the end surface of the roller brush, especially at the edge corners. It is difficult to process the end surface of the roller brush using traditional methods. Extrusion can shorten the state of high moisture content of the roller brush, reduce residual moisture after cleaning, and quickly drain it through squeezing to avoid moisture breeding bacteria or odor.

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0017] See also Figures 1 to 11 The present invention provides a technical solution: a mobile dust removal device for household service, comprising a handheld mobile bracket 1, a dust collection chamber 11 being fixedly connected to the mobile bracket 1, and a sliding frame 12 being slidably connected to the mobile bracket 1; A dust removal roller brush device 2 is fixedly connected to the sliding frame 12, and the dust removal roller brush device 2 is located next to the dust suction chamber 11. The dust removal roller brush device 2 includes a rotating motor 21 fixedly connected to the sliding frame 12, and the main shaft of the rotating motor 21 is connected to a rotating rod 22, and a roller brush 23 is provided on the rotating rod 22. The dust removal roller brush device 2 also includes a cleaning member 3 for removing impurities on the roller brush 23, and the cleaning member 3 is transmission-connected to the rotating rod 22. The sliding frame 12 is provided with an end face processing member 5 at the end of the roller brush 23.

[0018] In this embodiment, there are two cleaning members 3, both of which are rotatably connected to the sliding frame 12, and the two cleaning members 3 are respectively located at both ends of the roller brush 23, and the two cleaning members 3 include a shell 31 fixedly connected to the outer wall of the sliding frame 12, a rotating gear 32 is fixedly connected to the rotating rod 22, and a rotating disk 33 is rotatably connected to the sliding frame 12, and an annular gear ring 34 meshing with the rotating gear 32 is provided on the outer wall of the rotating disk 33, and an adjusting plate 35 is slidably connected to the end surface of the rotating disk 33, and a movable frame 36 is slidably connected to the shell 31, and a connecting rod 37 is provided between the adjusting plate 35 and the movable frame 36, and the connecting rod 37 is hingedly connected to the adjusting plate 35 and the movable frame 36; A mounting rod 38 is fixedly connected between the two movable frames 36 on the two cleaning members 3. A scraper 39 capable of adjusting the deflection angle is rotatably connected to the mounting rod 38. The scraper 39 is made of silicone and extends toward the inside of the roller brush 23. A movable groove 310 is formed on the housing 31 and is slidably connected to the mounting rod 38. A sealing plate 311 is also fixedly connected to the mounting rod 38, and the sealing plate 311 covers the movable groove 310. The scraper 39 is made of glass fiber reinforced nylon, which is wear-resistant and silent. The sealing plate 311 is set to prevent the scraper 39 from scraping impurities on the roller brush 23, and the impurities enter the shell 31 and the sliding frame 12, thereby preventing long-term accumulation of dust from affecting the equipment.

[0019] When the handheld mobile bracket 1 moves, the rotating rod 22 can be rotated under the drive of the rotating motor 21. The rotating rod 22 rotates to make the roller brush 23 roll the brush 23 on the ground to be cleaned. The dust and other impurities on the ground are sucked into the dust suction chamber 11 by the roller brush 23 in cooperation with the suction of the dust suction chamber 11 to absorb the dust and impurities on the ground. The rotation of the rotating rod 22 drives the rotating gear 32 to rotate. The rotation of the rotating gear 32 enables the annular gear ring 34 to drive the rotating disk 33 to rotate. The rotation of the rotating disk 33 drives the adjusting plate 35 slidably connected to the end surface of the rotating disk 33 to perform a circular motion. The adjusting plate 35 pulls the connecting rod 37 to move. The other end of the connecting rod 37 enables the movable frame 36 to slide back and forth on the shell 31. The mounting rod 38 on the movable frame 36 drives the scraper 39 to extend toward the inside of the roller brush 23. The scraper 39 extends toward the inside of the roller brush 23 to clean soft garbage such as long hair and fibers. The roller brush 23 may be entangled due to continuous involvement. The intermittent action of the scraper 39 can periodically extend toward the inside of the scraper 39 to cut or peel off the entangled objects on the roller brush 23, reducing the risk of jamming. The scraper 39 is extended intermittently toward the roller brush 23 to avoid the scraper 39 and the roller brush 23 from being in continuous contact, thereby increasing the mechanical friction resistance, leading to increased energy consumption of the equipment, increased noise, etc.

[0020] In this embodiment, a control electric cylinder 13 is fixedly connected to the outer wall of the dust suction chamber 11, and the telescopic end of the control electric cylinder 13 is connected to the outer wall of the sliding frame 12. The axis of the rotating disk 33 is also clamped and connected to the rifle rod 4. The rotating disk 33 is rotatably connected to a transmission gear 41, and the transmission gear 41 is provided with a sleeve spirally connected to the rifle rod 4. A rack 42 meshing with the transmission gear 41 is fixedly provided on the adjustment plate 35, and the rifle rod 4 is also fixedly connected to an external chuck 43; An L-shaped groove 44 is formed on the movable bracket 1, and an oblique groove 45 is formed on the outer wall of the sliding bracket 12. The oblique groove 45 is located below the L-shaped groove 44. A connecting bracket 46 is rotatably connected to the external chuck 43. The connecting bracket 46 is vertically provided with a vertical rod 47. The vertical rod 47 is inserted into the L-shaped groove 44 and the oblique groove 45, and a pulley 48 is provided on the vertical rod 47 to be slidably connected to the L-shaped groove 44 and the oblique groove 45. When the operator drives the sliding frame 12 to move toward the dust suction chamber 11 by controlling the electric cylinder 13, the sliding frame 12 will drive the roller brush 23 to move to the side of the dust suction chamber 11, thereby shortening the distance between the roller brush 23 and the dust suction chamber 11, which is convenient for adsorbing impurities in the roller brush 23. As the sliding frame 12 moves, the vertical rod 47 set in the L-shaped groove 44 and the inclined groove 45 will move under the restriction of the two. When it moves to the end of the inclined groove 45 and the L-shaped groove 44, the vertical rod 47 will move toward the end of the L-shaped groove 44 under the restriction of the two. At this time, the vertical rod 47 will drive the connecting frame 46 to move, and the connecting frame 46 will move toward the axis of the rotating disk 33 at this time. The connecting frame 46 drives the clamping outer disk to move. The rotation of the gear 41 causes the adjustment plate 35 to move, and the eccentric distance of the adjustment plate 35 from the rotating disk 33 changes. At this time, when the rotating disk 33 rotates to cause the adjustment plate 35 to perform a circular motion, the adjustment plate 35 pulls the movable frame 36 to move through the connecting rod 37, thereby lengthening the moving distance of the movable frame 36. When the moving distance of the movable frame 36 becomes longer, the scraper 39 provided on the mounting rod 38 extends toward the axis of the roller brush 23, thereby gradually inserting the scraper 39 into the interior of the roller brush 23. When the roller brush 23 is being cleaned, it is generally divided into surface dust, middle debris and root entanglements. The scraper 39 gradually extends to the inside of the roller brush 23, which can clean the roller brush 23 more thoroughly and remove impurities inside the roller brush 23 in a targeted manner, so that the dust collection chamber 11 can adsorb the impurities inside the roller brush 23.

[0021] In this embodiment, there are two end surface processing parts 5, which are respectively arranged on the sliding frame 12 and located at both ends of the roller brush 23. The two end surface processing parts 5 include a convex plate 51 fixedly connected to the inner wall of the sliding frame 12, and the convex plate 51 is rotatably connected to the rotating rod 22. The rotating rod 22 is rotatably connected to a deflection frame 52, and one end of the deflection frame 52 is fixedly connected to a clamping rod 53. A U-shaped groove 54 is opened on the movable frame 36, and the clamping rod 53 on the deflection frame 52 extends into the U-shaped groove 54; The deflection frame 52 is hingedly connected to a contact frame 55 at one end away from the clamping rod 53, and a torsion spring is provided between the contact frame 55 and the deflection frame 52. A limiting ball 56 is fixedly connected to the contact frame 55. The limiting ball 56 abuts against the outer end surface of the convex plate 51 under the restriction of the torsion spring, and when the limiting ball 56 contacts the convex end of the convex plate 51, it can move toward the end surface of the roller brush 23. When the control electric cylinder 13 drives the sliding frame 12 to move toward the dust suction chamber 11, the distance of the eccentric movement of the adjustment plate 35 on the rotating disk 33 is changed under the restriction of the vertical rod 47, so that the movable frame 36 can move a longer distance toward the roller brush 23. While the movable frame 36 moves, the U-shaped groove 54 provided on the movable frame 36 will cause the deflection frame 52 to deflect on the rotating rod 22. When the movable frame 36 moves a distance that allows the deflection frame 52 to drive the limiting ball 56 to contact the raised end of the convex plate 51, the limiting ball 56 moves toward the end surface of the roller brush 23 under the restriction of the raised end of the convex plate 51. At this time, the limiting ball 56 abuts against the end surface of the roller brush 23. The limiting sphere 56 squeezes and forces the end face of the roller brush 23 to deform. Through mechanical friction and squeezing, the dust, hair, debris and other debris embedded in the root of the brush are squeezed out, especially the fine particles that are difficult to remove by traditional cleaning. At this time, the dust absorption of the dust suction chamber 11 can effectively remove the impurities remaining in the brush. Dust, hair and other impurities are easily accumulated on the end surface of the roller brush 23, especially at the edge corners. It is difficult to process the end surface of the roller brush 23 using traditional methods. Extrusion can shorten the state of high moisture content of the roller brush 23, reduce residual moisture after cleaning, and quickly drain it through squeezing to avoid moisture breeding bacteria or odor.

[0022] The use method and advantages of the present invention: The use method of the mobile dust removal device for household service, the working process is as follows: like Figures 1 to 11 As shown: when the handheld mobile bracket 1 moves, the rotating rod 22 can be rotated under the drive of the rotating motor 21, and the rotating rod 22 rotates to cause the roller brush 23 to roll the brush 23 on the ground to be cleaned, and the dust and other impurities on the ground are sucked into the dust suction chamber 11 by the roller brush 23 in cooperation with the suction of the dust suction chamber 11 to absorb the dust and impurities on the ground; The rotation of the rotating rod 22 drives the rotating gear 32 to rotate. The rotation of the rotating gear 32 enables the annular gear ring 34 to drive the rotating disk 33 to rotate. The rotation of the rotating disk 33 drives the adjusting plate 35 slidably connected to the end surface of the rotating disk 33 to perform a circular motion. The adjusting plate 35 pulls the connecting rod 37 to move. The other end of the connecting rod 37 enables the movable frame 36 to slide back and forth on the shell 31. The mounting rod 38 on the movable frame 36 drives the scraper 39 to extend toward the inside of the roller brush 23. The scraper 39 extends toward the inside of the roller brush 23 to clean soft garbage such as long hair and fibers. The roller brush 23 may be entangled due to continuous involvement. The intermittent action of the scraper 39 can periodically extend toward the inside of the scraper 39 to cut or peel off the entangled objects on the roller brush 23, reducing the risk of jamming. When the operator drives the sliding frame 12 to move toward the dust suction chamber 11 by controlling the electric cylinder 13, the sliding frame 12 will drive the roller brush 23 to move to the side of the dust suction chamber 11, thereby shortening the distance between the roller brush 23 and the dust suction chamber 11, which is convenient for adsorbing impurities in the roller brush 23. As the sliding frame 12 moves, the vertical rod 47 set in the L-shaped groove 44 and the inclined groove 45 will move under the restriction of the two. When it moves to the end of the inclined groove 45 and the L-shaped groove 44, the vertical rod 47 will move toward the end of the L-shaped groove 44 under the restriction of the two. At this time, the vertical rod 47 will drive the connecting frame 46 to move, and the connecting frame 46 will move toward the axis of the rotating disk 33 at this time. The connecting frame 46 drives the clamping outer disk to move. The rotation of the gear 41 causes the adjustment plate 35 to move, and the eccentric distance of the adjustment plate 35 from the rotating disk 33 changes. At this time, when the rotating disk 33 rotates to cause the adjustment plate 35 to perform a circular motion, the adjustment plate 35 pulls the movable frame 36 to move through the connecting rod 37, thereby lengthening the moving distance of the movable frame 36. When the moving distance of the movable frame 36 becomes longer, the scraper 39 provided on the mounting rod 38 extends toward the axis of the roller brush 23, thereby gradually inserting the scraper 39 into the interior of the roller brush 23. When the control electric cylinder 13 drives the sliding frame 12 to move toward the dust suction chamber 11, the eccentric movement distance of the adjustment plate 35 on the rotating disk 33 changes under the restriction of the vertical rod 47, so that the movable frame 36 can move a longer distance toward the roller brush 23. While the movable frame 36 moves, the U-shaped groove 54 provided on the movable frame 36 will cause the deflection frame 52 to deflect on the rotating rod 22. When the distance moved by the movable frame 36 is sufficient to enable the deflection frame 52 to drive the limiting ball 56 to contact the raised end of the cam 51, the limiting ball 56 moves toward the end face of the roller brush 23 under the restriction of the raised end of the cam 51. At this time, the limiting ball 56 abuts against the end face of the roller brush 23.
