Description

Technical Field

[0001] This invention relates to the field of vacuum cleaner technology, and in particular to a cleaning device. Background Technology

[0002] Currently, most handheld vacuum cleaners on the market are cleaned in one of two ways: First, by removing the dust cup, filter, and other parts and cleaning the surface dust by hand. This cleaning process is complicated and inefficient. Second, the dust cup is integrated with the main body, and a scraper handle is set on the main body to drive the scraper inside the dust cup. Since the dust cup cannot be removed, you can only hold the main body with one hand and operate the scraper handle with the other hand when cleaning dust. Because the entire vacuum cleaner is relatively heavy, this cleaning process is also very inconvenient. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a cleaning device that eliminates the need for manual cleaning, simplifies and facilitates the cleaning process, and improves cleaning efficiency.

[0004] This invention is achieved through the following technical solution:

[0005] A cleaning device includes a body and a dust cup, which are detachably connected. The dust cup includes a dust bin and a filter and a scraper disposed inside the dust bin. The scraper is slidably fitted around the filter for cleaning dust or particles on the filter. The outer wall of the dust bin has an opening, and a drive component that moves the scraper is disposed inside the opening.

[0006] Furthermore, the opening is filled with a sealing strip, and the sealing strip has a sliding hole for the drive component to slide.

[0007] Furthermore, a cover plate is provided on the outside of the opening, and a pair of sealing elements are provided inside the cover plate at the position corresponding to the moving hole. The pair of sealing elements are symmetrically arranged about the moving hole, and one end of the sealing element abuts against the cover plate by a spring, and the other end abuts against the sealing strip.

[0008] Furthermore, an elastic element is provided inside the cover plate to prevent the drive component from sliding.

[0009] Furthermore, the outer side of the cover plate is provided with sliding holes for the drive components to operate.

[0010] Furthermore, the driving component includes an operating handle and a connecting rod. One end of the connecting rod passes through the opening and is fixedly connected to the dust scraper, while the other end is exposed on the outside of the dust bin and fixedly connected to the operating handle.

[0011] Furthermore, the bottom of the dustbin is equipped with a bottom cover, one end of which is rotatably connected to the dustbin, and the other end is equipped with a buckle that engages with a locking block on the outside of the dustbin.

[0012] Furthermore, the driving component also includes a vertical rod, which is fixedly connected to the connecting rod and is positioned directly above the buckle. When the driving component moves downward to its lowest point, the vertical rod can drive the buckle to disengage from the locking block.

[0013] Furthermore, a pair of limiting plates are protruding from the outer wall of the dust bin, and a limiting track for accommodating the vertical rod is formed between the pair of limiting plates.

[0014] Furthermore, a sensor is fixed on the side of the machine body near the scraper, and a control board and a working motor are installed inside the machine body. The control board is electrically connected to both the sensor and the working motor.

[0015] When the user does not operate the drive component, the sensor can detect the position signal of the scraper component. At this time, the control board can control the working motor to start normally.

[0016] When the user does not operate the drive unit, the scraper will move out of the sensor's sensing range under the drive unit's influence. At this time, the control board will not be able to activate the working motor.

[0017] Furthermore, the driving component includes a control lever, a cover, and an operating component. One end of the control lever passes through the opening and is fixedly connected to the dust scraper, while the other end is exposed outside the dust bin and fixedly connected to the cover. The operating component is connected to the cover.

[0018] Furthermore, the drive component also includes a bushing disposed between the control lever and the cover.

[0019] Furthermore, a first track component that limits the running direction of the control lever and a second track component that limits the running direction of the cover are also fixed on the outside of the dust bin.

[0020] Compared with the prior art, the advantages of this invention are:

[0021] 1. By mounting the drive unit on the dustbin, it can be removed along with the dustbin. The drive unit can drive the scraper to clean the dust or particles on the filter. This cleaning device does not require manual cleaning, and the cleaning process is simple, convenient and improves cleaning efficiency.

[0022] 2. When the scraper moves downward, in addition to scraping, it can also trigger the sensor to stop the device from running. At the same time, when the scraper moves to the bottom, the bottom cover can be opened.

[0023] 3. By filling the opening with a sealing strip, and the sealing strip having a sliding hole for the drive component to slide, the sealing strip is made of elastic material, specifically rubber material, and the sliding hole can achieve self-adaptive sealing.

[0024] 4. A pair of symmetrical seals are installed on both sides of the moving hole of the sealing strip, with one end of the seal abutting against the cover plate via a spring and the other end abutting against the sealing strip. The pair of seals work together to apply pressure to the sealing strip, ensuring that the moving hole is sealed. Attached Figure Description

This cleaning device eliminates the need for manual cleaning, making the cleaning process simple, convenient, and improving cleaning efficiency.

[0039] like Figure 1 and Figure 9 As mentioned above, since the driving component 6 is installed in the dust cup 2, the dust cup 2 is suitable for various types of machine bodies, such as vertical machine bodies, gun-type machine bodies, etc.

[0040] The following is a detailed description of an embodiment of the cleaning device.

[0041] First Embodiment

[0042] A cleaning device according to an embodiment of the present invention includes a body 1 and a dust cup 2, which are detachably connected. The dust cup 2 includes a dust bin 3 and a filter element 4 and a scraper element 5 disposed within the dust bin 3. The scraper element 5 is slidably fitted around the outer periphery of the filter element 4 for cleaning dust or particles on the filter element 4. The outer wall of the dust bin 3 is provided with an opening 30, and a drive element 6 for driving the scraper element 5 is disposed within the opening 30. By setting the drive element 6 on the side wall of the dust bin 3, the drive element 6 can be arranged at any position around the axis of the dust bin 3 (360°), and can be removed with the dust bin 3. The drive element 6 can drive the scraper element 5 to clean the dust or particles on the filter element 4. This cleaning device eliminates the need for manual cleaning, making the cleaning process simple and convenient and improving cleaning efficiency.

[0043] The opening 30 is filled with a sealing strip 7. The sealing strip 7 has a sliding hole (not shown in the figure) for the drive component 6 to slide. The direction of the sliding hole is consistent with the running direction of the drive component 6. The sealing strip is made of elastic material, specifically rubber material. The sliding hole can achieve self-adaptive sealing.

[0044] A cover plate 8 is provided on the outer side of the opening 30. A pair of sealing elements 9 are provided inside the cover plate 8 at the position corresponding to the moving hole. The pair of sealing elements 9 are symmetrically arranged about the moving hole, and one end of the sealing element 9 abuts against the cover plate 8 through a spring 10, and the other end abuts against the sealing strip 7. When the driving component 6 is not operated, the pair of sealing elements 9 together apply pressure to the sealing strip 7 to ensure that the moving hole is in a sealed state.

[0045] Specifically, a column 90 protrudes from the side of the seal 9 near the cover plate 8. A storage groove 900 for accommodating the spring 10 is provided in the column 90. The end of the spring 10 away from the seal 9 is fixedly connected to the inner wall of the cover plate 8. In this embodiment, the end of the spring 10 away from the seal 9 is welded to the inner wall of the cover plate 8.

[0046] The outer side 80 of the cover plate 8 is provided with a sliding hole 81 for the drive member 6 to run, and the direction of the sliding hole 81 is consistent with the moving hole.

[0047] The driving component 6 includes an operating handle 60 and a connecting rod 61. One end of the connecting rod 61 passes through the moving hole and is fixedly connected to the scraper 5, while the other end is exposed on the outside of the dust bin 3 and fixedly connected to the operating handle 60.

[0048] The bottom of the dustbin 3 is provided with a bottom cover 11. One end of the bottom cover 11 is rotatably connected to the dustbin 3, and the other end is provided with a buckle 110, which engages with a locking block 31 on the outside of the dustbin 3. When the driving member 6 moves downward to the lowest position, the driving member 6 can drive the buckle 110 to disengage from the locking block 31.

[0049] Specifically, the bottom cover 11 is hinged to the dustbin 3, and a torsion spring 112 is provided between the bottom cover 11 and the dustbin 3.

[0050] The driving component 6 also includes a vertical rod 62, which is fixedly connected to the connecting rod 61. The vertical rod 62 is located directly above the buckle 110. When the driving component 6 moves downward to the lowest point, the vertical rod 62 can drive the buckle 110 to disengage from the locking block 31.

[0051] Specifically, the lower end of the vertical rod 62 has a first wedge-shaped surface 620, and the buckle 110 has a second wedge-shaped surface 111 above it. When the driving member 6 moves downward to the lowest point, the first wedge-shaped surface 620 and the second wedge-shaped surface 111 engage.

[0052] The cover plate 8 also contains a spring-loaded element to prevent the drive element 6 from sliding. (Reference) Figures 2-5 In one embodiment of the present invention, a pair of limiting plates 32 protrude from the outer wall of the dustbin 3, forming a limiting track 320 between the pair of limiting plates 32 to accommodate the vertical rod 62. The elastic element is a tension spring 15, one end of which is fixed to the top of the cover plate 8, and the other end is fixedly connected to the connecting rod 61. In this embodiment, both ends of the tension spring 15 are welded. (See reference) Figure 6 and Figure 7 In another embodiment of the present invention, the elastic element may be a top spring 16, a horizontal bar 63 is integrally formed on the vertical bar 62, and a limiting block 33 is protruding on the inner wall of the cover plate 8. One end of the top spring 16 abuts against the horizontal bar 63 and the other end abuts against the limiting block 33.

[0053] refer to Figure 8 A sensor 12 is fixed to the side of the machine body 1 near the scraper 5. A control board 13 and a working motor 14 are installed inside the machine body 1. The control board 13 is electrically connected to both the sensor 12 and the working motor 14. When the user does not operate the drive component 6, the sensor 12 can sense the position signal of the scraper 5. At this time, the control board 13 controls the working motor 14 to start normally. When the user does not operate the drive component 6, the scraper 5 moves out of the sensing range of the sensor 12 under the drive of the drive component 6. At this time, the control board 13 controls the working motor 14 to stop. Specifically, the sensor 12 is a microswitch, Hall effect switch, etc.

[0054] During operation, after the vacuuming action is completed, the operating handle 60 on the drive component 6 is slid towards the bottom cover 11. At this time, the connecting rod 61 causes the scraper 5 to release from the micro switch. The micro switch reacts to the control board 13, and the working motor 14 stops operating. The operating handle 60 continues to be pressed down. The operating handle 60 drives the scraper 5 to clean the dust or particles adsorbed on the filter 4 through the connecting rod 61. When the operating handle 60 moves to the end of the movable part, the bottom of the vertical rod 62 contacts the buckle 110 on the bottom cover 11. The buckle 110 pops open, and the bottom cover 11 opens, realizing the opening of the cover and emptying of dust. Finally, the drive component 6 is reset by the tension spring 15 or the top spring 16, which at the same time drives the scraper 5 to reset. When the operating handle 60 moves the scraper 5 downward, the sealing strip 7 completes the closing and sealing action. In addition, to better ensure the sealing effect of the dust bin 3, a pair of sealing elements 9 can be added to better assist the sealing of the moving holes on the sealing strip 7. Specifically, when the connecting rod 61 slides through the moving holes between the sealing strips 7, the sealing strip 7 self-seales, and the springs 10 on the left and right sides of the connecting rod 61 apply a pushing force to the sealing elements 9. The pushing force is transmitted to the sealing strip 7 so that it can better complete the sealing action.

[0055] Second Embodiment

[0056] like Figure 10-11 As shown, compared to the first embodiment, adjustments have been made to the structure of the driving component 6 and the outer wall of the dustbin 3, specifically as follows: The driving component 6 includes a control rod 64, a cover 65, an operating component 66, and a bushing 67. One end of the control rod 64 passes through the opening 30 and is fixedly connected to the scraper 5, while the other end is exposed on the outside of the dustbin 3 and fixedly connected to the cover 65. The operating component 66 is connected to the cover 65, and the bushing 67 is disposed between the control rod 64 and the cover 65. The top of the cover 65 is fixedly connected to the cover plate 8 via a return spring 70, which allows the driving component 6 to self-reset. A sealing gasket 71 is provided at the junction of the cover 65 and the outer wall of the dustbin 3. Simultaneously, when the driving component 6 moves downward to its lowest position, the cover 65 can cause the latch 110 to disengage from the latch block 31.

[0057] The outside of the dustbin 3 is also fixed with a first track component 68 for the running direction of the limit control rod 64 and a second track component 69 for the running direction of the limit cover 65.

[0058] During operation, after the vacuuming action is completed, the operating component 66 on the drive component 6 is slid towards the bottom cover 11. At this time, the control lever 64 causes the scraper component 5 to release from the micro switch. The micro switch reacts to the control board 13, and the working motor 14 stops operating. The operating component 66 continues to be pressed down. The operating component 66 drives the scraper component 5 to clean the dust or particles adsorbed on the filter component 4 through the control lever 64. When the operating component 66 moves to the end of the movable part, the bottom of the cover 65 contacts the buckle 110 on the bottom cover 11. The buckle 110 pops open, and the bottom cover 11 opens, realizing the opening of the cover and emptying of dust. Finally, the drive component 6 is reset by the return spring 70, which at the same time drives the scraper component 5 to reset. When the operating component 66 drives the scraper component 5 to move downward via the control lever 64, the cover 65 moves along the second track component 69, and the control lever 64 moves along the first track component 68. This allows the control lever 64 and the cover 65 to move to the same side simultaneously. Since a longitudinal force is generated between the control lever 64 and the cover 65 during the movement, a bushing 67 is provided between the control lever 64 and the cover 65 to achieve a self-lubricating effect.

[0059] The present invention has the following beneficial effects:

[0060] 1. By setting the drive unit 6 on the dust bin 3, it can be removed along with the dust bin 3. The drive unit 6 can drive the scraper 5 to clean the dust or particles on the filter element 4. This cleaning device does not require manual cleaning, the cleaning process is simple and convenient and improves cleaning efficiency.

[0061] 2. When the scraper 5 moves downward, in addition to scraping, it can also trigger the sensor 12 to stop the device from running. At the same time, when the scraper 5 moves to the bottom, the bottom cover 11 can be opened.

[0062] 3. By filling the opening 30 with a sealing strip 7, and the sealing strip 7 having a movable hole for the drive component 6 to slide, the sealing strip is made of elastic material, specifically rubber material, and the movable hole can achieve self-adaptive sealing.

[0063] 4. A pair of symmetrical seals 9 are provided on both sides of the moving hole of the sealing strip 7, with one end of the seal 9 abutting against the cover plate 8 via a spring 10 and the other end abutting against the sealing strip 7. The pair of seals 9 together apply pressure to the sealing strip 7 to ensure that the moving hole is in a sealed state.

[0064] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
