[0020] Figure 2 This is a control flow chart of the present invention. DETAILED DESCRIPTION

[0021] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0022] It should be noted that the words "up", "down", "left", "right", "front" and "rear" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0023] A cotton swab automatic disinfection device mainly includes a transmission mechanism, a sensor control mechanism, an ultraviolet lamp and a power supply device. The transmission mechanism is used to push the cotton swab forward, the sensor control mechanism is used to achieve precise control of the cotton swab manufacturing process and the disinfection process, and the ultraviolet lamp is used to sterilize and disinfect the cotton swab. The various components of the device are described in detail one by one below.

[0024] First, there are two transmission mechanisms that are arranged vertically, both of which adopt a wheel-axle structure, including a driving wheel and a driven wheel connected by a belt. The driving wheel is coaxially connected to a servo motor. Driven by the servo motor, the driving wheel rotates and drives the driven wheel to rotate through the belt, thereby pushing the cotton swab forward. In order to better fix the servo motor, a lateral side wheel is installed on the side of the servo motor.

[0025] The sensing control mechanism includes a sensor and a control system. There are two sensors, which are Omron's E3Z-D61 diffuse reflection photoelectric sensor. The sensor is set at the front end of the device. When the cotton swab is transmitted to the end, the sensor at the front end receives the information and transmits the information to the control system. The motor stops rotating and then stops working. When transmission is required again, the object sends an operation instruction to the signal receiving end. The signal receiving end converts the received signal into assembly language and transmits it to the control system. The control system converts the signal into an electrical signal to control the operation of the servo motor. The servo motor transmits power to the transmission mechanism to push the cotton swab forward. At the same time, the purpose of ultraviolet disinfection can be achieved.

[0026] like Figure 1 As shown in the figure, the device circuit uses the AT89C51 chip. The P0 port of the chip is connected to a digital tube to display the time. The P1 port is connected to 5 buttons to control the direction and speed of the motor. The P2 port is connected to the ULN2003A non-gate drive circuit to drive the stepper motor. The XTAL1 and XTAL2 pins are used to provide an external oscillation source to the clock circuit on the chip. The RST pin guides the reset of the circuit. Pressing the connected button will start the circuit reset.

[0027] The device is made of 6061 aluminum alloy, and its allowable shear stress is 370Mpa. According to the maximum shear stress formula:

[0028]

[0029] It is much smaller than the allowable shear stress, so this material is qualified.

[0030] The power source is a lithium battery with a capacity of 4*10^5 mAh. The lithium battery is rechargeable and can be used repeatedly.

[0031] like Figure 2 As shown, a control method for a cotton swab automatic disinfection device, the specific steps are as follows:

[0032] Step 1: The object sends an operation instruction to the signal receiving end, and the signal receiving end converts the received signal into assembly language and passes it to the control system.

[0033] Step 2: The control system converts the signal into an electrical signal to control the operation of the servo motor. The servo motor transmits power to the transmission mechanism to push the cotton swab forward. At the same time, the ultraviolet lamp sterilizes and disinfects the cotton swab.

[0034] Step 3: When the cotton swab reaches the end, the sensor at the front end receives the information and transmits it to the control system, and the control system transmits the received information to the signal receiving end again.

[0035] Step 4: The signal receiving end feeds back to the operating end, the motor stops rotating and then stops working.

[0036] It should be noted that the drawings only illustrate the technical ideas of the present invention, and the protection scope of the present invention cannot be limited by this shape. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications all fall within the protection scope of the claims of the present invention.
