Description

Technical Field

[0001] This invention relates to the field of vacuum cleaner technology, specifically to an automatic dust collection and charging base for vacuum cleaners with a display screen. Background Technology

[0002] With the development and iteration of vacuum cleaner technology, dust collection charging bases have emerged and are increasingly widely used in order to achieve centralized dust collection and cleaning and integrated vacuum cleaner charging functions. These products typically require a charging rack, charging components, and dust collection mechanisms such as a filter and vacuum motor. However, common dust collection charging bases lack visual designs for operational parameters such as filtration and clogging status, as well as adjustable modes for different usage scenarios, resulting in inefficient operation of the dust collection mechanism. Charging is achieved by manually pressing a control switch on the dust collection charging base after the vacuum cleaner is connected to its conductive plate. This design means that pressing the control switch immediately powers on the charging components, posing a risk of accidental electric shock. Furthermore, internal space constraints make the assembly and removal of common axially inserted filter structures and embedded structures requiring manual manipulation of gaps inconvenient, resulting in cumbersome and troublesome disassembly operations. Summary of the Invention

[0003] The purpose of this invention is to address the problems of existing dust collection and charging bases, such as the lack of a visual design for operation, the risk of electric shock during charging, and the inconvenience of disassembling and assembling the filter and dust collection structure, which make the product inconvenient to operate. Therefore, this invention provides an automatic dust collection and charging base for vacuum cleaners with a display screen.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an automatic dust collection and charging base for a vacuum cleaner with a display screen, comprising:

A first guide strip is provided on the first connecting plate. The second linkage is slidably connected to the first guide strip. A second spring is provided between the second linkage and the first cover plate. A connecting block on the rear side of the first handle is slidably connected to the strip-shaped guide groove of the second linkage.

A third locking block at the top of the second handle and a locking block at the bottom of the second cover plate are engaged with the locking slot at the third opening.

[0032] In summary, due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0033] 1. This vacuum cleaner's automatic dust collection and charging base features a display screen that shows real-time dust filtration detection, internal negative pressure, charging status of the charging components, and battery level. This enhances the visibility of the device's operation, allowing for timely component maintenance and adjustments to ensure efficient and stable operation. It also includes DIY multi-scenario adjustments and DIY mode memory functions, improving ease of use, efficiency, and user experience while reducing operational difficulty. The charging structure features a charging rack with a clamp, improving positioning stability during charging. In addition to the conventional conductive sheet structure, the charging components utilize a linked mechanism and a micro-switch at a corresponding location. This ensures that the charging circuit is connected only when the vacuum cleaner is docked, preventing accidental contact with the conductive sheet and improving the safety of the charging components. Multiple openings and covers facilitate convenient inspection and maintenance of the internal components. The internal filter structure features a quick-release design, enhancing the ease of disassembly and cleaning. This enables visualization of the dust collection and charging base's usage status based on the display screen, low suction power loss with high adaptability to various usage scenarios, efficient dust collection, safe charging of the vacuum cleaner, convenient opening and closing of the cover, easy disassembly and assembly of the dust collection and filter structure, and internal component inspection and maintenance functions.

[0034] 2. Based on the top side assembly and positioning design of the dust collection structure, combined with the bottom positioning structure where the upper and lower positioning rings are interlocked and snapped together, the assembly stability of the dust collection bag can be improved, ensuring tightness and achieving a stable filtration effect. Compared with the common axial insertion snap-fit ​​method, it can improve the assembly convenience in narrow spaces.

[0035] 3. The second locking block and the top locking slot of the air outlet are elastically pre-tightened and embedded in the positioning structure based on the U-shaped connector. When removing the HEPA cover, the embedded structure can be pulled out by pulling the lever through the linkage between the sleeve and the second connecting plate. Compared with the common method of removing the embedded structure by manually squeezing into the gap and rubbing it out, this design is simpler and more convenient.

[0036] 4. The locking and unlocking operation of the first cover is achieved through the sliding connection of the second linkage component, which is parallel to the overall airflow direction of the dust collection and charging base and perpendicular to the direction of the force generated by the pressure difference on both sides, in conjunction with the linkage of the first handle component. This improves the convenience of opening and closing the first cover and enhances the closing stability of the first cover when the dust collection and charging base is in operation, forming a negative pressure airflow inside, and using the dust collection structure. It also reduces the impact of the internal negative pressure on the connection between the first cover and the shell, preventing loosening, air leakage, and the problem of the first cover automatically falling off after the dust collection and charging base finishes collecting dust and the internal negative pressure is restored. The assembly structure of the second cover's handle component and the third opening also adopts a sliding connection method perpendicular to the direction of the force generated by the pressure difference on both sides, achieving a similar effect to the first cover.

[0059] Example 1:

[0060] Please see Figure 1-13 This invention provides a technical solution: an automatic dust collection and charging base for a vacuum cleaner with a display screen, comprising:

[0061] The base 1 includes a first housing 11 and a second housing 12 located inside the first housing 11, and a display screen 10 is disposed on its surface;

[0062] The dust collection duct 2 has a duct connector 21 at its top and a communication port 22 inside that communicates with the duct structure 23 and the inner cavity of the second housing 12. An elastic baffle 24 is provided on the communication port 22.

[0063] The charging rack 3 has a clamp 31 at its end;

[0064] The charging component 4 is assembled inside the clamp 31 and includes a mounting bracket 41, a conductive sheet 42, a micro switch 43, and a first linkage member 44 slidably connected to the mounting bracket 41. The first connector 421 at the outer end of the conductive sheet 42 extends from the fourth opening 412 to the outside of the clamp 31. The first linkage member 44 is linked with the button 432 of the micro switch 43.

[0065] The dust collection structure 5 is detachably assembled inside the second housing 12;

[0066] The first cover 6 is positioned directly opposite the dust collection structure 5 and is fitted onto the first opening 111 of the first housing 11 and the second opening 121 of the second housing 12.

[0067] Vacuum motor 7;

[0068] The air outlet filter 8 is detachably embedded in the air outlet 72 of the third housing 71 of the vacuum motor 7. The display screen 10 is used to display the dust filtration detection of the dust collection structure 5, the negative pressure inside the dust collection charging base, the charging status of the charging component 4, and the power level. The dust filtration detection and the negative pressure inside the dust collection charging base are achieved by installing a pressure gauge or flow rate gauge on the inner side of the dust collection structure to detect the pressure difference and flow rate.

[0069] In addition, in this embodiment, the dust collection charging stand is also equipped with a data interface and can also be connected to the network to input the DIY design of the operating parameters of the dust collection charging stand for different usage scenarios. The working mode of the dust collection charging stand can be operated through the adjustment buttons next to the display screen 10 to ensure high efficiency and low energy consumption. It realizes the DIY multi-use scenario adjustment and DIY mode memory functions of the dust collection charging stand, thereby improving the convenience of operation and user experience and reducing the difficulty of operation.

[0070] The second cover 9 is positioned opposite the air outlet filter 8 and is mounted on the third opening 113 of the first housing 11.

[0071] When using the above structure, please refer to [link / reference]. Figure 3 , 4The dust collection structure, such as the dust cup of the vacuum cleaner, or the dust collection tube is connected to the air duct connector 21. When the vacuum motor 7 runs, the elastic baffle 24 is opened and the connecting port 22 is opened. The airflow carries the dust into the air duct structure and passes through the dust collection structure 5 for filtration, the inner cavity of the third shell 71 for air guidance, the outlet filter 8 for air filtration, and the second cover 9 for air outlet, so as to realize the dust collection function of the vacuum cleaner to discharge dust or to collect dust and clean the surface to be cleaned.

[0072] This vacuum cleaner's automatic dust collection and charging base features a display screen that shows real-time dust filtration detection, internal negative pressure, charging status of the charging components, and battery level. This enhances the visibility of the device's operation, allowing for timely component maintenance and adjustments to ensure efficient and stable operation. It also includes DIY multi-scenario adjustment and DIY mode memory functions, improving ease of use, efficiency, and user experience while reducing operational difficulty.

[0073] Its charging structure features a charging rack with a clamp, which improves the positioning stability of the vacuum cleaner during charging. In addition to the conventional conductive sheet structure, the charging component uses a designed linkage and a micro switch in the corresponding position. This ensures that when the vacuum cleaner is connected to the component, the micro switch must be triggered simultaneously to connect the charging circuit, thus avoiding accidental contact of the conductive sheet and preventing electric shock. This improves the safety of the charging component.

[0074] With multiple openings and covers, the internal components of the dust collection and charging base can be easily inspected and maintained. The internal filter structure adopts a quick-release design, which improves the convenience of disassembly and cleaning operations.

[0075] The dust collection structure 5, which plays a major role in intercepting, filtering, and collecting dust discharged from the vacuum cleaner or collected through the dust collection pipe and floor brush connected to the air duct connector 21, has a quick-release design within the second housing 12. (See also: [link to relevant documentation]). Figure 4-6 Specifically, the dust collection structure 5 includes a dust collection bag 51, an upper positioning plate 52, an upper positioning ring 53, and a bottom filter guide structure. The upper positioning plate 52 is slidably connected to the card plate 122 at the top inside the second housing 12. An arc-shaped guide plate 521 is provided on the upper positioning plate 52, and the arc-shaped guide plate 521 is slidably connected to the arc-shaped guide groove 123 at the top inside the second housing 12.

[0076] When using the above structure, i.e., when disassembling the dust collection structure 5, open the first cover 6, hold the upper positioning plate 52, and pull it out laterally so that it slides out along the clamping plate 122. The arc-shaped guide plate 521 and the arc-shaped guide groove 123 cooperate to guide and disengage, and simultaneously the upper positioning ring 53 disengages from the filter guide structure, thereby achieving quick disassembly of the dust collection structure 5. When assembling, assemble the upper positioning ring 53 onto the filter guide structure and press the upper positioning plate 52 into the clamping plate 122. When the arc-shaped guide plate 521 and the arc-shaped guide groove 123 are completely spliced, the assembly is complete. At this time, the through holes on the arc-shaped guide plate 521 and the upper positioning plate 52 are tightly connected to the air duct structure 23 through the sealing ring. The arc-shaped structure design facilitates the confirmation of the assembly completion, improves the standardization of assembly operations, and thus ensures the tightness of the structural connection and the high efficiency and stability of the equipment operation. The design of the above dust collection filter structure, through lateral assembly positioning, improves the ease of assembly in confined spaces compared to the common axial insertion and snap-fit ​​method.

[0077] Continue reading Figure 6 The filter guide structure includes a first guide plate 54 and a second guide plate 55 mounted on the mounting ribs 124 inside the second housing 12, and a filter plate 56 mounted on the first guide plate 54 and the second guide plate 55. A first guide strip 542 is radially arranged on the first guide plate 54, and a motor positioning frame 551 is arranged on the second guide plate 55. A second guide strip 552 is spirally arranged on the outer side of the motor positioning frame 551.

[0078] The above design can achieve stable airflow at the air outlet of the dust collection and filtration structure. By designing radiating guide strips, the airflow in this area is accelerated to reduce the flow rate reduction caused by the filtration structure. This makes it easier for the airflow velocity in each area to meet the standard under the same vacuum motor operating parameters, thereby reducing the operating requirements and energy consumption of the vacuum motor and achieving a low-energy flow guidance effect with low suction loss.

[0079] To improve the ease of opening and closing the first cover, and to ensure the stability of its closure during dust collection and charging, when the dust collection structure 5 is in use, and to reduce the impact of the internal negative pressure on the connection between the first cover and the housing, preventing loosening and air leakage, and to prevent the first cover from automatically detaching after dust collection and the creation of internal negative pressure, thus avoiding cross-contamination between the internal and external environments, please refer to the detailed structural design of the first cover 6. Figure 8-10 Specifically, the first cover 6 includes a first cover plate 61, an L-shaped hinge 62, and a locking structure disposed in the first recess 611 of the first cover plate 61. The L-shaped hinge 62 is embedded and hinged to the hinge groove 112 of the first housing 11.

[0080] The locking structure includes a first handle 63 and a second linkage 64. The first handle 63 is hinged to the first connecting plate 612 of the first recess 611 on its side and a pre-tensioning torsion spring is provided at the connection. A first guide strip 613 is provided on the first connecting plate 612. The second linkage 64 is slidably connected to the first guide strip 613 on its side. A second spring 641 is provided between the second linkage 64 and the first cover plate 61. A connecting block 631 on the rear side of the first handle 63 is slidably connected in the strip guide groove 642 of the second linkage 64. A first locking block 643 on the second linkage 64 is correspondingly engaged with a locking slot on the first cover plate 61.

[0081] When using the first cover structure, hold the first handle 63 and pull it outwards. This causes the first handle 63 to rotate along the first connecting plate 612. Simultaneously, the connecting block 631 exerts a downward and outward squeezing force on the strip guide groove 642, causing the second linkage 64 to slide downwards. The first locking block 643 disengages from the locking slot on the first opening 111, releasing the first cover locking structure. The top of the first cover can then be pulled outwards, allowing the L-shaped hinge 62 to rotate stably outwards along the hinge groove 112, thus enabling the removal of the dust collection structure 5. After the first cover plate 61 is reset, releasing the first handle 63 allows the structure to reset via the pre-tensioned torsion spring and the second spring. The first cover 6 is then re-locked and positioned on the first housing 11, allowing for daily placement or use of the dust collection charging base.

[0082] By using the sliding connection of the second linkage component, which is parallel to the overall airflow direction of the dust collection and charging base and perpendicular to the direction of the force generated by the pressure difference on both sides, in conjunction with the linkage of the first handle component, the locking and unlocking operations of the first cover can be performed. This can improve the convenience of opening and closing the first cover, as well as the closing stability of the first cover when the dust collection and charging base is running, forming a negative pressure airflow inside, and using the dust collection structure 5. It can also reduce the impact of the internal negative pressure on the connection between the first cover and the shell, preventing it from loosening and causing air leakage, and preventing the first cover from automatically falling off after the dust collection and charging base ends and the internal negative pressure is restored.

[0083] The quick-release design structure of the air outlet filter is as follows: Figure 12As shown, specifically, the air outlet filter 8 includes a HEPA cover 81, a HEPA filter 82 assembled inside the HEPA cover 81, and a back frame 83 for positioning the HEPA filter 82. The back frame 83 is snapped into the inner side of the HEPA cover 81 for positioning, improving the ease of assembly and disassembly of the HEPA filter 82. One side of the HEPA cover 81 is snapped into the slot of the air outlet 72, and a U-shaped connector 811 is provided on the opposite side. The second snap block 812 at the top of the U-shaped connector 811 is snapped into the slot of the air outlet 72. This structure allows the assembled air outlet filter 8 to be snapped into one side and directly pressed into the air outlet 72 on the other side. Through the adaptive elastic deformation of the U-shaped connector 811, the elastically pre-tightened second snap block 812 can be assembled and positioned with the slot at the top of the air outlet 72, making the operation simple.

[0084] The assembly structure of the second cover 9's upper handle and the third opening 113 also adopts a sliding connection method perpendicular to the direction of movement of the force generated by the pressure difference on both sides, as shown in the following figure. Figure 11 , 13 The second cover 9 includes a second cover plate 91 with mesh and a second handle 92 slidably disposed within a second recess 911 of the second cover plate 91. A second guide strip 912 is disposed inside the second recess 911, and the second handle 92 is slidably connected to the second guide strip 912 on its side. A third spring 913 is disposed between the spring seat of the second recess 911 and the second handle 92. A third locking block 921 at the top of the second handle 92 and a locking block at the bottom of the second cover plate 91 engage with the locking slot at the third opening 113. The above design achieves an effect similar to that of the first cover 6.

[0085] Example 2:

[0086] Continue reading Figure 1-2 Based on the above embodiment one, preferably, an inverted conical guide groove 32 is provided on the inner side of the clamp 31. The width of the conical guide groove 32 gradually decreases along the insertion direction of the vacuum cleaner, which improves the positioning stability when the vacuum cleaner is assembled and charged. The conductive sheet 42 is a Z-shaped conductive sheet. The connecting column 411 on the mounting bracket 41, together with bolts or pins, positions the middle part of the conductive sheet 42. The second connector 422 on the inner side of the conductive sheet 42 is connected to the micro switch 43 through a wire. The first linkage 44 is slidably connected in the sliding hole 413 and a first spring 441 is provided between its inner end and the mounting bracket 41. A wedge-shaped abutment surface is provided on its outer end, and a side extension plate 442 is provided on its side. An elastic lever 431 is provided on the end face of the micro switch 43, which abuts against the side extension plate 442. The button 432 is on the movement trajectory of the elastic lever 431.

[0087] When the above structure is in use, the vacuum cleaner is assembled in the clamp 31 along the conical guide groove 32, and the conductive sheets of the two are connected. During this process, the first linkage 44 is pressed and slides inward along the sliding hole 413. The side extension plate 442 simultaneously squeezes the elastic lever 431, so that pressing the button 432 connects the charging circuit. This avoids electric shock caused by accidental contact of the conductive sheet and improves the safety of the charging component.

[0089] Continue reading Figure 6-7 Based on the above embodiment one, preferably, the inner end of the first guide strip 542 is connected to the lower positioning ring 541, and the opposite end faces of the upper positioning ring 53 and the lower positioning ring 541 are provided with rounded serrations for mutual snap-fit ​​assembly. Based on the top lateral assembly positioning design of the dust collection structure, combined with the bottom positioning structure of the upper positioning ring 53 and the lower positioning ring 541 snap-fit ​​assembly, the assembly stability of the dust collection bag can be improved, ensuring tightness and achieving a stable filtration effect. Moreover, compared with the common axial insertion snap-fit ​​method, it can improve the assembly convenience in narrow spaces.

[0090] Example 4:

[0091] Continue reading Figure 12 Based on the above embodiment one, preferably, a second connecting plate 813 is provided on the outer side of the U-shaped connector 811, and a pull rod 84 is provided on the second connecting plate 813. The sleeve 841 on the pull rod 84 is sleeved on the second connecting plate 813. Based on the elastic pre-tightening assembly and embedding positioning structure of the second locking block 812 and the top locking slot of the air outlet 72 implemented by the U-shaped connector 811, when the HEPA cover 81 is removed, the embedded structure can be pulled out by pulling the pull rod 84 through the linkage between the sleeve 841 and the second connecting plate 813. Compared with the common method of removing the embedded structure by manually squeezing into the gap and prying it out, this design is simpler and more convenient.
