[0060] Embodiment 1:

[0061] See also Figure 1-13 The utility model provides a technical solution: an automatic dust collection and charging stand for a vacuum cleaner with a display screen, comprising:

[0065] The charging assembly 4 is mounted inside the clamp 31, and includes a mounting frame 41, a conductive sheet 42, a micro switch 43, and a first linkage member 44 slidably connected to the mounting frame 41, wherein a first connector 421 at an outer end of the conductive sheet 42 extends from a fourth opening 412 to the outside of the clamp 31, and the first linkage member 44 is linked to a button 432 of the micro switch 43;

[0066] A dust collecting structure 5, which is detachably assembled in the second housing 12;

[0068] Vacuum motor 7;

[0069] 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 filtering detection of the dust collecting structure 5, the negative pressure inside the dust collecting charging seat, the charging status of the charging component 4, and the power level; wherein, the dust filtering detection and the negative pressure inside the dust collecting charging seat are realized by setting a barometer or a flow meter on the inner side of the dust collecting structure to detect the pressure difference and flow rate;

[0070] In addition, in the present embodiment, the dust collecting and charging stand is also provided with a data interface, and can also be connected to the network to input the DIY design of the operating parameters of the dust collecting and charging stand for different usage scenarios, and operate the working mode of the dust collecting and charging stand through the adjustment button next to the display screen 10, so as to ensure high efficiency and low energy consumption, realize the DIY multi-usage scene adjustment and DIY mode memory functions of the dust collecting and charging stand, thereby improving the convenience of operation and user experience, and reducing the difficulty of operation;

[0071] The second sealing cover 9 is arranged opposite to the air outlet filter 8 and is assembled on the third opening 113 of the first shell 11 .

[0072] When using the above structure, please refer to Figure 3 , 4, connect the dust storage structure such as the dust cup of the vacuum cleaner or the dust collecting pipe to the air duct joint 21, and run the vacuum motor 7 to make the elastic baffle 24 flip open, and the connecting port 22 open. The airflow drives the dust into the air duct structure and passes through the filtration of the dust collecting structure 5, the inner cavity diversion of the third shell 71, the air outlet filtration of the air outlet filter 8, and the air outlet of the second cover 9 in turn, so as to realize the dust discharge of the vacuum cleaner or the dust collection and cleaning of the surface to be cleaned.

[0073] The automatic dust collection and charging stand of the vacuum cleaner is designed with a display screen that can display dust filtration detection, negative pressure inside the dust collection and charging stand, charging status of charging components, and power status in real time, thereby improving the visualization of equipment operation so that corresponding component maintenance and adjustments can be made in a timely manner to ensure efficient and stable operation of the dust collection and charging stand. It also has functions such as DIY multi-usage scenario adjustment and DIY mode memory, which can improve the convenience, efficiency and user experience of operation and reduce the difficulty of operation.

[0074] A charging rack with a clamp is provided on its charging structure, which can improve the positioning stability of the vacuum cleaner when charging. In addition to the conventional conductive sheet structure, the charging component has a designed linkage part and a micro switch at the corresponding position. When the vacuum cleaner is docked with it, the micro switch needs to be triggered at the same time to achieve the connection of the charging circuit, avoiding electric shock caused by accidental touching of the conductive sheet and improving the safety of the use of the charging component.

[0075] By setting up multiple openings and covers, convenient inspection and maintenance of the internal components of the dust collection and charging stand can be achieved, and the internal filtering structure adopts a quick-disassembly design to improve the convenience of its disassembly and cleaning operations.

[0076] The dust collecting structure 5 in the second housing 12 plays a major role in intercepting, filtering and collecting dust discharged from the vacuum cleaner or dust collected by connecting the dust collecting pipe and the floor brush through the air duct connector 21. Figure 4-6 Specifically, the dust collecting structure 5 includes a dust collecting bag 51, an upper positioning plate 52, an upper positioning ring 53 and a bottom filtering guide structure. The upper positioning plate 52 is slidably connected to the clamping plate 122 at the top of the second shell 12. An arc guide plate 521 is provided on the upper positioning plate 52. The arc guide plate 521 is slidably connected to the arc guide groove 123 at the top of the second shell 12.

[0077] When the above structure is used, that is, when the dust collecting structure 5 is disassembled, the first cover 6 is opened, the upper positioning plate 52 is held and pulled out sideways to slide out along the card plate 122, and the arc guide plate 521 and the arc guide groove 123 cooperate to guide and disengage, and the upper positioning ring 53 and the filter guide structure are disengaged simultaneously, thereby realizing the quick disassembly of the dust collecting structure 5; when assembling, the upper positioning ring 53 is assembled on the filter guide structure, and the upper positioning plate 52 is pressed into the card plate 122, and when the arc guide plate 521 and the arc guide groove 123 are completely assembled, the assembly is completed, at this time, the through holes on the arc guide plate 521 and the upper positioning plate 52 are tightly connected with the air duct structure 23 through the sealing ring. Through the arc structure design, it is convenient to confirm the assembly completion, improve the standardization of assembly operation, and then ensure the tightness of structural connection and the efficient and stable operation of the equipment. The design of the above dust collecting and filtering structure is positioned by lateral assembly, which can improve the convenience of assembly in a narrow space compared with the common axial insertion and clamping method.

[0078] Continue reading Figure 6 The filtering and guiding structure includes a first guide plate 54 and a second guide plate 55 mounted on the mounting rib 124 in the second shell 12, and a filter plate 56 mounted on the first guide plate 54 and the second guide plate 55. The first guide plate 54 is radially provided with a first guide strip 542, the second guide plate 55 is provided with a motor positioning frame 551, and the outer side of the motor positioning frame 551 is spirally provided with a second guide strip 552.

[0079] The above design can achieve stable diversion of the airflow at the outlet of the dust collecting and filtering structure. Through the design of radial guide strips, the airflow in this area is accelerated to reduce the flow rate reduction caused by the filtering structure on the airflow filtration, so that under the same vacuum motor operating parameters, the airflow velocity in each area is easier to meet the standard, thereby reducing the operating requirements and energy consumption of the vacuum motor and achieving a low-energy diversion effect with low suction loss.

[0080] In order to improve the convenience of opening and closing the first cover, and to ensure the closing stability of the first cover when the dust collecting charging station is operating to collect dust, negative pressure airflow is formed inside, and the dust collecting structure 5 is in use, and to reduce the influence of the internal negative pressure on the connection between the first cover and the shell, to avoid the connection being loosened and causing air leakage, and to prevent the first cover from automatically falling off after the dust collecting charging station ends dust collection and negative pressure is formed inside, resulting in cross contamination between the internal environment and the external environment, the specific structural design of the first cover 6 is shown in FIG. Figure 8-10 Specifically, the first cover 6 includes a first cover plate 61, an L-shaped hinge 62 and a locking structure arranged in a first recess 611 of the first cover plate 61, and the L-shaped hinge 62 is embedded and hinged in a hinge groove 112 of the first shell 11.

[0081] The locking structure includes a first buckle member 63 and a second linkage member 64, the first buckle member 63 is hinged at the side of the first connecting plate 612 of the first recess 611 and a pre-tightening torsion spring is arranged at the connection, the first connecting plate 612 is provided with a first guide strip 613, the second linkage member 64 is slidably connected to the first guide strip 613 at the side, a second spring 641 is arranged between the second linkage member 64 and the first cover plate 61, the connecting block 631 at the rear side of the first buckle member 63 is slidably connected in the strip guide groove 642 of the second linkage member 64, and the first clamping block 643 on the second linkage member 64 is correspondingly clamped with the clamping socket on the first cover plate 61.

[0082] When the first cover structure is used, the first handle 63 is held and pulled outward, so that the first handle 63 rotates along the first connecting plate 612, and the connecting block 631 simultaneously generates a downward and outward squeezing force on the strip guide groove 642, so that the second linkage 64 slides downward, and the first clamping block 643 is disengaged from the clamping slot on the first opening 111, and the first cover locking structure is released, and the top of the first cover can be pulled outward, so that the L-shaped hinge 62 rotates stably outward along the hinge groove 112, and the above-mentioned dust collection structure 5 can be removed. After the first cover plate 61 is reset, the first handle 63 can be released to achieve structural reset by pre-tightening the torsion spring and the second spring, and the first cover 6 is re-locked and positioned on the first shell 11, and the dust collection charging stand can be placed or used daily.

[0083] The locking and unlocking operations of the first cover are performed by sliding the second linkage member parallel to the overall airflow movement direction of the dust collector charging stand and perpendicular to the movement direction of the force formed by the pressure difference on both sides in coordination with the linkage of the first buckle member. This can improve the convenience of the opening and closing operation of the first cover, as well as the closing stability of the first cover when the dust collector charging stand is operating to collect dust, negative pressure airflow is formed inside, and the dust collecting structure 5 is in use. This can reduce the influence of the internal negative pressure on the connection between the first cover and the shell, avoid loosening and air leakage, and the problem of the first cover automatically falling off after the dust collector charging stand ends dust collection and the internal negative pressure is formed.

[0084] The quick-release design structure of the air outlet filter is as follows: Fig.12As shown, specifically: the air outlet filter 8 includes a hepa cover 81, a hepa 82 assembled in the hepa cover 81, and a back frame 83 for positioning the hepa 82. The back frame 83 is clamped and positioned with the inner side of the hepa cover 81 to improve the convenience of disassembly and assembly of the hepa 82. A clamping block on one side of the hepa cover 81 is clamped on the clamping port of the air outlet 72. A U-shaped connector 811 is arranged on the other side thereof. The second clamping block 812 at the top of the U-shaped connector 811 is clamped on the clamping port of the air outlet 72. The above structure enables the assembled air outlet filter 8 to be clamped on one side and directly pressed into the air outlet 72 on the other side. The assembly and positioning of the elastically pre-tightened second clamping block 812 and the clamping port at the top of the air outlet 72 can be realized through the adaptive elastic deformation of the U-shaped connector 811, and the operation is simple.

[0085] The assembly structure of the buckle member on the second cover 9 and the third opening 113 also adopts a sliding connection method perpendicular to the moving direction of the force formed by the pressure difference on both sides.
