In this embodiment, the cleaning tool comprises a cleaning unit 1 , an accessory unit 3 , and a connecting unit 2 connecting the cleaning unit 1 and the accessory unit 3 .

[0040] Among them, the cleaning unit 1 in this embodiment is preferably a handheld vacuum cleaner, which includes an air inlet pipe 15, a dust collecting device 13 arranged at the bottom of the air inlet pipe 15, a driving device 14 connected to the air inlet pipe 15, a grip 11 located at the bottom of the driving device 14, and a power supply system 12. Specifically, the driving device 14 includes a motor and an impeller, and the motor can drive the impeller to generate suction. At the same time, the driving device 14 is fluidly connected to the air inlet pipe 15, so the external airflow carrying dust is sucked into the handheld vacuum cleaner 1 by the driving device 14 through the air inlet pipe 15; the dust collecting device 13 is connected to the air inlet pipe 15 through a seal such as HEPA. After the external airflow carrying dust enters the handheld vacuum cleaner 1, it is guided into the dust collecting device 13 by the air inlet pipe 15. After being filtered by the filtering device, the airflow is discharged outside the handheld vacuum cleaner 1, and the dust is stored in the dust collecting device 13; the power supply system 12 provides driving force for the driving device 14. In this embodiment, the power supply system 12 includes a battery pack, and the handheld vacuum cleaner 1 is powered by the battery pack. In other embodiments, the power supply system 12 can be directly connected to an external power supply to provide power for the handheld vacuum cleaner 1 through the external power supply; the grip 11 can be held by a user, so that the user can carry the handheld vacuum cleaner 1 for cleaning. It should be noted that, in other implementations, the cleaning unit 1 may also be a barrel-type vacuum cleaner or other cleaning devices that can be connected to an accessory unit, and is not limited to a handheld vacuum cleaner.

[0041] The accessory unit 3 in this embodiment is a floor brush assembly. When the user uses the handheld cleaning device 1 for cleaning, the floor brush assembly can assist the user in cleaning, thereby improving cleaning efficiency, saving time, and improving user experience. It should be noted that the accessory unit 3 can also be other cleaning accessories such as a long flat nozzle. When performing cleaning operations, the user can replace the cleaning accessories to meet various cleaning needs.

[0042] The connecting unit 2 is used to connect the floor brush assembly 3 and the handheld vacuum cleaner 1. The connecting unit 2 includes a connecting piece 22 and a docking piece 23. The connecting piece 22 is connected to the floor brush assembly 3, and the docking piece 23 is connected to the handheld vacuum cleaner 1. At the same time, the connecting piece 22 can be connected to the docking piece 23, so the floor brush assembly 3 can be connected to the handheld vacuum cleaner 1 through the connecting unit 2. Specifically, in this embodiment, the connecting piece 22 includes a mounting tube 221, a connecting tube 222, and an extension tube 223. One end of the extension tube 223 is connected to the floor brush assembly 3, and the other end passes through the mounting tube 221 and is connected to the connecting tube 222. Preferably, the extension tube 223 is fixedly connected to the mounting tube 221 and the connecting tube 222 respectively by two groups of rivets; the connecting tube 222 is at least partially accommodated in the docking piece 23 and connected to the docking piece 23; the docking piece 23 is riveted to the handheld vacuum cleaner 1, so that the floor brush assembly 3 can be connected to the handheld vacuum cleaner 1. It should be noted that, in a preferred embodiment, the extension tube 223 is connected to the floor brush assembly 3 through a detachable snap-on element, so that it is more convenient for the user to replace the accessories as needed; at the same time, the connecting tube 222 is rotatably connected to the docking member 23, so that the floor brush assembly 3 can rotate relative to the docking member 23, which will be described in detail later; the extension tube 223 can also be fixed to the mounting tube 221 by rivets and connected to the connecting tube 222 by snaps, so that the extension tube 223 can also be fixedly connected to the mounting tube 221 and the connecting tube 222. In other embodiments, if the handheld vacuum cleaner 1 does not need to perform long-distance cleaning, the connecting member 2 may not include the extension tube 223, that is, the handheld vacuum cleaner 1 can be directly connected to the accessory 3 through the mounting tube 221 by snaps or the like; at the same time, the connecting member 22 including the mounting tube 221 and the connecting tube 222 is only a preferred embodiment for easy assembly. In other embodiments, the mounting tube 221 and the connecting tube 222 can be designed as an integral molding.

[0043] The connection unit 2 further includes an operating member 21 sleeved on the connection member 22. In the present embodiment, the operating member 21 is sleeved on the mounting tube 221, and the operating member 21 can drive the mounting tube 221 to rotate. Specifically, the operating member 21 is also provided with at least two matching parts. In the present embodiment, the operating member 21 includes three matching parts, specifically a first matching part 214, a second matching part 213 and a third matching part 210, and the matching parts have basically the same structure. However, it should be noted that in other embodiments, the operating member may also include only two matching parts or more than three matching parts. The operating member 21 further includes a grip body 211, and the matching part further includes a Correspondingly, the mounting tube 221 is also provided with a guide portion 2211, and the matching portion can be at least partially accommodated in the guide portion 2211; when the operating member 21 is pulled, the convex rib of the matching portion can move along the guide portion 2211, so that the operating member 21 can slide relative to the mounting tube 221; when the operating member 21 is rotated, the convex rib of the matching portion can be engaged with the guide portion 2211, so that the operating member 21 can drive the mounting tube 221 to rotate together. At the same time, since the mounting tube 221 is fixedly connected with the connecting tube 222 and the extension tube 223 by rivets, the rotation of the mounting tube 221 can drive the connecting tube 222 and the extension tube 223 to rotate together, so that the user only needs to rotate the operating member 21 to rotate the floor brush assembly 3. It should be noted that the mounting tube 221 is also provided with a stopper 2212, and the stopper 2212 can cooperate with the operating member 21. When the operating member 21 is pulled to a certain position, the stopper 2212 limits the movement of the operating member 21 to remind the user not to continue pulling the operating member 21. At the same time, the matching portion in this embodiment is completely accommodated in the guide portion 2211, that is, when the operating member 21 is rotated, a pair of convex ribs of the matching portion abut against the guide portion 2211 at the same time, so that the guide portion 2211 and the operating member 21 rotate together, so that the mounting tube 221 also rotates together with the operating member 21. However, in other embodiments, the matching portion can also be only partially accommodated in the guide portion 2211, that is, only one convex rib is accommodated in the guide portion 2211, and when the operating member 21 is rotated, only one convex rib abuts against the guide portion 2211, which can also achieve the above function.

[0044] Further, the cleaning tool also includes a seal 5, and the seal 5 is clamped between the handheld vacuum cleaner 1 and the connecting member 22. Specifically, the seal 5 is clamped between the air inlet port of the handheld vacuum cleaner 1 and the connecting pipe 222. In a preferred embodiment, the seal 5 is sleeved on the air inlet port of the handheld vacuum cleaner 1. When the operating member 21 drives the connecting pipe 222 to rotate, the seal 5 can improve the air tightness of the cleaning tool. The seal 5 also includes a plastic gasket (not shown) sleeved on its body, so when the operating member 21 drives the connecting pipe 222 to rotate, the seal 5 can also reduce the friction resistance between the connecting pipe 222 and the handheld vacuum cleaner 1, so that the user only needs a small force to rotate the operating member, thereby improving the user experience. It should be noted that the seal 5 is sleeved on the air inlet port of the handheld vacuum cleaner 1 is only a preferred embodiment for easy installation. In other embodiments, the seal 5 can also be arranged on the connecting pipe 222.

[0045] In this embodiment, the docking member 23 includes a tubular body and a sliding portion 232 disposed on the inner surface of the tubular body. The connecting tube 222 further includes a slide rail 2221 having at least two ends 2220 , and the sliding portion 232 can slide along the slide rail 2221 . Specifically, when the connecting tube 222 extends into the tubular body along the direction of pulling the operating member 21 and moves to a certain position, the sliding portion 232 can cooperate with the slide rail 2221 to limit the connecting tube 222 from continuing to move in the direction of pulling the operating member, so that the connecting tube 222 can be connected to the docking member 23; when the operating member 21 is rotated, the connecting tube 222 is driven by the operating member 21 and rotates together, and the sliding portion 232 slides on the slide rail 2221, and since the slide rail 2221 is also provided with two end portions 2220, when the sliding portion 23 respectively abuts against the two end portions 2220, the operating member 21 cannot continue to rotate. At this time, the position of the operating member 21 is the first position and the second position of the operating member 21; the first position and the second position are also the locking positions where the operating member 21 cannot continue to rotate, and the operating member 21 can move between the first position and the second position. In a preferred embodiment, the sliding portion 232 is a protrusion, but in other embodiments, the sliding portion 232 may also be other components that can move on the slide rail.

[0046] The tubular body of the docking member 23 is also provided with a clamping portion 231, and the clamping portion 231 can cooperate with the matching portion of the operating member 21 to limit the relative rotation between the docking member 23 and the connecting member 22. Specifically, the matching portion includes a pair of convex ribs, and the pair of convex ribs can cooperate with each other to form a receiving space, and the clamping portion 231 can be clamped in the receiving space; corresponding to the positions of the two end portions 2220 of the slide rail 2221, the operating member 21 is also provided with two matching portions, so when the operating member 21 is in one of the first position or the second position, the clamping portion 231 can be clamped with one of the matching portions, so that the docking member 23 is fixedly connected to the operating member 21, and the cleaning tool is in the first state or the second state. One; pull the operating member 21, the coupling part and the holding part 231 are disengaged, and the cleaning tool is out of the first state or the second state. At this time, the operating member 21 and the docking member 23 can rotate relative to each other; rotate the operating member 21 to the other of the first position or the second position, and when the pulling force on the operating member 21 is removed, the holding part 231 is engaged with the other coupling part, and the docking member 23 is fixedly connected with the operating member 21 again, and the cleaning tool is in the first state or the second state. Therefore, the user only needs to pull the operating member 21, rotate the operating member 21 to the first position or the second position, and then remove the pulling force on the operating member 21, and the floor brush assembly 3 can maintain its current position. In this way, the user can easily change the angle of the floor brush assembly 3 to perform cleaning operations. After cleaning, the above operation can be performed again to change the position of the floor brush assembly 3 for storage. It should be noted that, in this embodiment, the clamping portion 231 is preferably a convex block with a size suitable for the matching portion, and the convex block can be clamped on the matching portion, so that when the operating member 21 is in the first position or the second position, the pulling force on the operating member 21 is removed, the operating member 21 is reset, and the convex block is clamped on the matching portion. At the same time, in a preferred embodiment, the docking member 23 is also provided with a reinforcing rib 235 to improve the strength of the tubular body when the tubular body is connected to the connecting pipe 222.
