In the figure: 1-a motor; 2-a circuit board; 3-a battery; 4-stationary knife assembly; 5-moving the knife assembly; 6-a first fixed seat; 7-rotating the bracket; 8-moving blade; 9-intelligent switch; 10-a conductive pin; 11-a second fixed seat; 12-a front housing; 13-a rear housing; 14-a handle; 15-a switching assembly.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 and 2, the lint trimmer with automatic start and stop function of the present invention comprises a housing, a blade structure installed in the housing, a motor 1 for driving the blade structure to work, a circuit board 2, and a battery 3 connected to the motor 1 and the circuit board 2, wherein the blade structure comprises a fixed blade assembly 4 and a movable blade assembly 5, the fixed blade assembly 4 comprises a cover body and a net-shaped fixed blade installed at one end of the cover body, the movable blade assembly 5 comprises a first fixing seat 6, a rotating bracket 7 installed on the first fixing seat 6, and a movable blade 8 installed on the rotating bracket 7, the rotating bracket 7 is in transmission connection with the motor 1, the movable blade 8 is in contact with the net-shaped fixed blade, an intelligent switch 9 for controlling the working state of the motor 1 is installed on the first fixing seat 6, and the intelligent switch 9 is connected to the circuit board 2.

The smart switch 9 includes a distance sensor or a tact switch.

The distance sensor includes an ultrasonic sensor, a laser sensor, or an infrared sensor. The infrared sensor is connected to the circuit board 2 via a conductive pin 10. The distance sensor may determine the operating state of the motor 1 based on the distance between the hair bulb trimmer and the object to be trimmed.

The working principle of the distance sensor is adopted: after the power supply is switched on, the motor 1 can drive the movable blade 8 to rotate and stop outputting, after the self-checking is finished, the motor 1 completely stops working, and meanwhile, the transmitting end of the distance sensor transmits invisible infrared pulse light to wait for the work of a user. When the user presses the hair bulb trimmer close to the clothes, the distance sensor receives reflected pulse infrared light, a signal is output to the circuit board 2, and the motor 1 starts to work. When the user lifts his hand, the distance sensor does not receive the reflected pulse infrared ray, and outputs a signal to the circuit board 2, so that the motor 1 stops working.

In a similar way, the working principle of the tact switch is adopted: after the power is switched on, the motor 1 can drive the movable blade 8 to rotate and stop outputting, and after the self-checking is finished, the motor 1 completely stops working to wait for the user to work. When the user presses the lint trimmer against the clothes, the tact switch outputs a signal to the circuit board 2, and the motor 1 starts to operate. When the user lifts the hand, the tact switch outputs a signal to the circuit board 2 due to the pressure being removed, and the motor 1 stops working.

The motor 1 is installed in the first fixing seat 6.

Still install second fixing base 11 on the first fixing base 6, battery 3 and circuit board 2 are installed respectively in second fixing base 11.

The casing comprises a front casing 12, a rear casing 13 and a handle 14 arranged at the lower part of the rear casing 13, wherein the front casing 12 is covered outside the tool bit structure.

A switch assembly 15 is mounted on the rear end of the rear case 13, and the switch assembly 15 is connected to the circuit board 2.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
