[0038] The mode switching device includes a mode switching base 2610 that at least partially houses one end of a vacuum motor 2400, a motor cover 2630 that at least partially houses the other end of the vacuum motor 2400 and is connected to the mode switching base 2610, and a triggerable air duct component 2650; wherein when the air duct component 2650 is in a first position, the vacuum motor 2400 is in a first operating mode; and when the air duct component 2650 is in a second position, the vacuum motor 2400 is in a second operating mode.

The central extension direction of the connecting hole 2616 is perpendicular to the central extension direction of the vacuum motor 2400, and the central extension direction of the connecting channel 2614 is parallel to the central extension direction of the vacuum motor 2400. The motor cover 2630 includes a motor cover cavity 2632 located therein and at least partially housing one end of the vacuum motor 2400, a first connecting port 2634 located on one side of the motor cover cavity 2632 and communicating with a first airflow channel, and a second connecting port 2638 communicating with a second airflow channel. The first connecting port 2634 and the second connecting port 2638 have a height difference in the vertical horizontal direction and are spaced apart in the circumferential direction. The duct component 2650 includes a main duct 2652 reciprocating in the connecting channel 2614, a branch duct 2653 perpendicularly connected to the main duct 2652, a first branch duct inlet 2654 on one side of the branch duct 2653, a second branch duct inlet 2656 on the other side of the branch duct 2653, a sliding plate 2658 connected to either the main duct 2652 or the branch duct 2653, and a mounting post 2659 at one end of the branch duct 2653 and fitted with an elastic element 2609. The first branch duct inlet 2654 is selectively connected to the first connecting port 2634 and operates in a first working mode, while the second branch duct inlet 2656 is selectively connected to the second connecting port 2638 and operates in the first working mode. The first airflow channel is a bypass channel 2636 located between the first connecting port 2634 and the air inlet side of the motor head. The second airflow channel is an inner channel located between the outer periphery of the motor cover 2630 and the inner side of the motor cover cavity 2632.

[0039] The vacuum motor 2400 includes a motor head that allows air intake and a motor tail, wherein the motor tail is located between the motor head and a partition plate 2620, and the central extension of the partition plate through-hole 2622 passes through the motor head; wherein the connecting cavity 2611 and the receiving cavity 2612 are isolated from each other, and the receiving cavity 2612 is located above the connecting cavity 2611 in a direction perpendicular to the horizontal plane. The vacuum motor 2400 is preferably a DC brushless motor.

[0040] This embodiment also includes an outer cover 2600 that houses the vacuum motor 2400 and the mode conversion device and is open at one end, and a partition plate 2620 that at least partially covers the open end of the outer cover 2600.

The partition plate 2620 is used to close the open end of the outer cover cavity 2604 and is generally plate-shaped, including a partition plate through hole 2622 adjacent to the filter element 2340 and centrally located.

[0041] like Figure 12-15 As shown, this utility model provides a second embodiment of the combination, which includes a handheld vacuum cleaner 2000 and a storage station 4000 for storing the handheld vacuum cleaner. The storage station 4000 includes a trigger lever 4240 that causes the air duct component 2650 to change position. The handheld vacuum cleaner is the same as the handheld vacuum cleaner in the first embodiment. The dust removal device 2200 includes a cyclone chamber 2220 located therein and a bottom cover 2240 located at one end of the cyclone chamber 2220.

[0042] The collection station 4000 includes a docking portion 4200 located at the top, a soft collection bag 4400 located therein for collecting dust from a handheld vacuum cleaner, and a triggering structure for triggering the end of the dust removal device 2200 to rotate open and empty the dust. A trigger rod 4240 is located on the docking portion 4200. In this embodiment, the handheld vacuum cleaner is in a second operating mode, and the dust removal device 2200 also includes a filter module located therein, with airflow flowing from the inside to the outside of the filter module. When the bottom cover rotates open, the dust on the bottom cover falls into the soft collection bag 4400 under gravity.

[0043] This utility model provides a third embodiment of a mode switching device applied in a handheld vacuum cleaner. The handheld vacuum cleaner 2000 includes a handheld body 2100, a dust removal device 2200 connected to the handheld body 2100, and a vacuum motor 2400 located inside the handheld body 2100. The mode switching device includes a mode switching seat 2610 that at least partially houses one end of the vacuum motor 2400, a motor cover 2630 that at least partially houses the other end of the vacuum motor 2400 and is connected to the mode switching seat 2610, and a hollow air duct component 2650 that can be triggered to move. The motor cover 2630 has first and second airflow channels communicating with the vacuum motor 2400. When the air duct component 2650 is in the first position, its interior is connected to the first airflow channel, and the vacuum motor 2400 is in the first working mode. When the air duct component 2650 is in the second position, its interior is connected to the second airflow channel, and the vacuum motor 2400 is in the second working mode.

[0044] When the vacuum motor 2400 is in the first working mode or the suction mode, the dirty airflow on the ground is drawn in by the accessory brush 2540, passes through the connecting pipe 2500 and the air inlet body 2120 in sequence, and then enters the dust removal device 2200 for cyclone dust separation. The separated airflow then passes through the filter cover 2300 and the outer surface of the filter element 2340 in sequence, that is, it moves from the outside to the inside to achieve double filtration. Then it enters the connecting cavity 2611 through the partition through hole 2622, and continues to flow along the connecting hole 261 on the side. 6. The air enters the main duct 2652. At this time, since one end of the first branch duct 2654 is connected to the first connecting port 2634, and the other end of the first connecting port 2634 is connected to the bypass channel 2636, the central air intake of the vacuum motor 2400 is completed. Then, the air flows out from one side of the motor housing 2632, that is, the second connecting port 2638, and then passes through the first motor rear air outlet channel 2680. Finally, it is discharged to the outside through the outer cover through hole 2640 located at the end of the first motor rear air outlet channel 2680.

[0045] When the vacuum motor 2400 is in the second working mode or the blowing mode, the outside airflow enters the outer cover cavity 2604 through the outer cover through hole 2640. At this time, one end of the first connecting port 2634 is connected to the outer cover through hole 2640. The outside airflow then enters the bypass channel 2636, thus completing the central air intake of the vacuum motor 2400. Then it flows out from one side of the motor cover cavity 2632, that is, the second connecting port 2638. At this time, since the second connecting port 2638 is connected to the second branch air duct port 2656, the outside airflow then passes through the second motor exhaust channel 2690 and enters downwards. The airflow enters the main duct 2652, then passes through the connecting hole 2616 on the side and enters the connecting cavity 2611. It then passes through the partition through hole 2622 and downwards through the inner surface of the filter cover 2300 and the filter element 2340, moving from the inside to the outside. This blowing action removes the dust remaining in the filter module, preventing dust accumulation and improving filtration performance. The airflow then moves further downwards. Since the bottom cover 2240 is rotated open at this time, the downward movement of the airflow, combined with gravity, causes the dust in the cyclone cavity 2220 to enter the soft collection bag 4400, thus completing the dust removal.

[0046] The advantages of this invention are: it has different working modes to cope with different working scenarios, reduces dust accumulation in the filter module, and facilitates product miniaturization.
