[0036] In order to more clearly illustrate the structural features and functions of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] like Figure 1-16As shown, a handheld cleaning brush in an embodiment of the utility model includes a shell component 1, wherein the shell component 1 includes a bottom shell 101, a battery compartment 102, a main control IC 103, a top shell 104, a switch slot 105, a switch 106, a charging port 107 and a sleeve 108, wherein the battery compartment 102 and the main control IC 103 are arranged inside the bottom shell 101, the top shell 104 is fixedly assembled on the bottom shell 101, and the switch slot 105 and the switch 106 are also arranged on the top shell 104, the switch 106 and the main control IC 103 are electrically connected, the main control IC 103 is used to control the rotation direction and rotation speed of the drive motor 4, and detect the obstacle current in the drive motor 4, the charging port 107 is fixedly arranged in the bottom shell 101 and is electrically connected to the battery compartment 102, and the sleeve 108 is fixedly assembled on one side of the bottom shell 101; a handle component 2, wherein the handle component 2 includes a card connector 201, a first A pipe handle 202, a second pipe handle 203, a third pipe handle 204, a grip 205 and a snap-in piece 206, the snap-in piece 201 is movably assembled on one side of the bottom shell 101, the first pipe handle 202, the second pipe handle 203 and the third pipe handle 204 are movably assembled in sequence, the end of the third pipe handle 204 is also inserted with a grip 205, and the snap-in piece 206 is also provided on the end of the snap-in piece 201 facing the bottom shell 101; a drive motor 4, the drive motor 4 is fixedly arranged inside the sleeve 108; a gear box assembly, the gear box assembly includes a bottom cover assembly 5, a middle cover assembly 6, a transmission gear set 7 and a top cover assembly 8; and a cleaning assembly 9, the cleaning assembly 9 includes a rotating shell 901, a plug interface 902 and a cleaning brush 903, the bottom of the rotating shell 901 is provided with a plug interface 902, the plug interface 902 is linked to the motor shaft of the drive motor 4, and a plurality of cleaning brushes 903 are fixedly assembled on the top of the rotating shell 901.

[0038] In actual application of this embodiment, when the handheld cleaning brush is used, the main body of the cleaning brush is composed of a bottom shell 101, a top shell 104 and a sleeve 108. The end of the bottom shell 101 is connected to a handle assembly 2 for holding the cleaning brush. A driving unit for driving the cleaning assembly 9 to rotate is installed inside the sleeve 108, including a driving motor 4, a bottom cover assembly 5, a middle cover assembly 6, a transmission gear set 7 and a top cover assembly 8 and a transmission structure. The plug-in interface 902 at one end of the rotating shell 901 is connected to the motor shaft of the driving motor 4, so that the several cleaning brushes 903 installed at the other end of the rotating shell 901 can perform a rotational cleaning function on the cleaning point during the rotation process. A main control IC 103 is arranged in the bottom shell 101, which can control the driving motor 4 to rotate. It rotates alternately in the clockwise direction at the same time, and the built-in power inverter of the main control IC103 alternately outputs 0.8S of forward power supply and 0.8S of reverse power supply, so that the cleaning brush rotates forward and then reversely and cyclically, simulating the function of manual wiping in the process of reciprocating rotation to obtain better decontamination effect. It has better cleaning ability than the traditional unidirectional rotating cleaning brush, and the current of the motor is controlled at 1-3A during normal operation. The current is judged by the main control IC. When the brush encounters an obstacle and the current becomes larger, the main control IC judges that the current is too large and immediately switches the current supply direction to drive the brush head to rotate in the opposite direction, avoiding motor blockage and reducing product blockage and shutdown to improve work efficiency. With the unique tooth-lip ratio design of the cleaning brush and the large torque, cleaning is more efficient, and it can clean a variety of production sites.

[0039] In one case of the present embodiment, during the use of the cleaning brush, the handle assembly 2 can be pulled away from one end of the bottom shell 101, so that the cleaning brush is in a short handle state, which can be convenient for cleaning on a desktop or at home. After the handle assembly 2 is installed, the lever arm of the handle can be lengthened, which is convenient for cleaning long-distance locations such as the ground and ceiling, thereby achieving the purpose of saving effort.

[0040] In one case of this embodiment, rotating shells 901 of different diameters can be selected according to different cleaning environments, and several rotating shells 901 of different diameters can be connected to one end of the motor shaft of the drive motor 4 through the plug interface 902, which can be easily replaced.

A guide groove 305 and a card interface 306 are also arranged on the charging base 301, and the guide groove 305 and the card interface 306 are both matched with the card connector 206.

[0042] In actual application of this embodiment, when the card connector 201 is inserted into the charging base 301, the card plates 206 at both ends of the card connector 201 slide in a directional manner in the guide groove 305. When the card plates 206 slide to the end position of the guide groove 305, the card connector 201 can be rotated to make the card plates 206 screwed into the card interface 306 for locking, so that the shell component 1, the handle component 2 and the charging component 3 are connected into a complete main structure.

[0043] In one case of this embodiment, the blocking piece 304 is attached to one end of the charging socket 302 by default, so that the socket slot 303 is in a blocked state, thereby preventing dust from entering the charging port and causing it to fail.
