所述控制装置包括主控制器，主控制器通过电机驱动模块控制步进电机11正转或反转，控制装置的基本原理如图7所示。所述手柄1上的按钮包括向主控制器输出开关量的第一按钮101和第二按钮103；手柄1表面还设有旋钮102，旋钮102与内置于手柄1的滑动变阻器R1相联动，滑动变阻器的可变端子连接主控制器内置的AD模块的输入引脚。旋钮102不同的档位对应不同的AD值（即经过分压后R1的可变端子与GND之间的电压的AD值），故主控制器根据当前AD值可判断旋钮102的档位，旋钮102的档位用于对应不同的出液速度，即不同的步进电机11转速。The control device includes a main controller, and the main controller controls the forward or reverse rotation of the steppingmotor 11 through a motor drive module. The basic principle of the control device is shown in FIG. 7 . The buttons on thehandle 1 include afirst button 101 and asecond button 103 that output switching values to the main controller; aknob 102 is also provided on the surface of thehandle 1, and theknob 102 is linked with the sliding rheostat R1 built in thehandle 1 to slide. The variable terminal of the varistor is connected to the input pin of the AD module built in the main controller. Different gears of theknob 102 correspond to different AD values (that is, the AD value of the voltage between the variable terminal of R1 and GND after voltage division), so the main controller can determine the gear of theknob 102 according to the current AD value. The gears of 102 are used to correspond to different liquid discharge speeds, that is, different rotational speeds of thestepping motor 11 .

The adapter is AC220V-DC12V.

所述加压腔2顶部设有盖板，打开盖板用于放入或取出储液瓶5，加压腔2内的储液瓶5置于支架8的两臂之间，推板12位于储液瓶5和支架8的底板之间。The top of the pressurizingchamber 2 is provided with a cover plate, and the cover plate is opened for putting in or taking out theliquid storage bottle 5. Theliquid storage bottle 5 in the pressurizingchamber 2 is placed between the two arms of thebracket 8, and thepush plate 12 is located between the two arms of thebracket 8. Between theliquid storage bottle 5 and the bottom plate of thebracket 8 .

所述加压腔2的后端连接手柄1。The rear end of thepressure chamber 2 is connected to thehandle 1 .

所述加压腔2的前端固定有伞形的防护罩3，当冲洗时，洗液冲击到患者身体难免会有液珠飞溅，防护罩3可以一定程度上遮挡液珠溅射到医师身上。An umbrella-shapedprotective cover 3 is fixed at the front end of thepressure chamber 2. When flushing, liquid droplets will inevitably splash when the lotion hits the patient's body.

储液瓶5类似于弹簧的特殊结构，使得其容积容易改变。The special structure of theliquid storage bottle 5 is similar to a spring, so that its volume can be easily changed.

推板12挤压储液瓶5的原理为：当步进电机11正向转动时，带动螺纹杆10正向转动，推板12与螺纹杆10通过螺纹孔配合，故推板12会沿着螺纹杆向前移动，同时由于光杆9的限制，推板12不会发生转动。推板12向前移动时，从储液瓶5底部挤压储液瓶5使之形变，发生如图3和图4所示的变化，过程中，储液瓶5的容积不断变小，内部的洗液被挤出，由于步进电机11的转速可以精确控制，故推板12的移动速度可精确控制，从而容易控制洗液的流量和流速。同理，当步进电机11反向转动时，推板12反向移动。The principle that thepush plate 12 squeezes theliquid storage bottle 5 is: when the steppingmotor 11 rotates in the forward direction, it drives the threadedrod 10 to rotate in the forward direction. The threaded rod moves forward, and at the same time, due to the restriction of thepolished rod 9, thepush plate 12 does not rotate. When thepush plate 12 moves forward, theliquid storage bottle 5 is squeezed from the bottom of theliquid storage bottle 5 to deform it, and the changes shown in Figures 3 and 4 occur. The lotion is squeezed out. Since the rotation speed of the steppingmotor 11 can be precisely controlled, the moving speed of thepush plate 12 can be precisely controlled, so that the flow and flow rate of the lotion can be easily controlled. Similarly, when the steppingmotor 11 rotates in the reverse direction, thepush plate 12 moves in the reverse direction.

主控制器使用STC15WS408A型号单片机，电机驱动芯片使用L298N型号，主控制器通过GPIO管脚连接电机驱动芯片的控制脚。步进电机11使用42HB34F08B型号，步进电机位于加压腔2内并部署于其尾部，第一按钮101和第二按钮103分别与一个按钮开关联动（即图7中的K1和K2），开关一端通过电阻连接GND，另一端连接主控制器的GPIO管脚，当开关按下时，GPIO检测为低电平，未按下时，GPIO内置弱上拉，故检测为高电平，由此可判断第一按钮101和第二按钮103是否按下。The main controller uses the STC15WS408A type single chip microcomputer, the motor driver chip uses the L298N type, and the main controller connects the control pins of the motor driver chip through the GPIO pins. Thestepper motor 11 uses the 42HB34F08B model. The stepper motor is located in thepressurized chamber 2 and deployed at its tail. Thefirst button 101 and thesecond button 103 are respectively linked with a button switch (ie K1 and K2 in FIG. 7 ), the switch One end is connected to GND through a resistor, and the other end is connected to the GPIO pin of the main controller. When the switch is pressed, the GPIO is detected as a low level. When it is not pressed, the GPIO has a built-in weak pull-up, so it is detected as a high level. It can be determined whether thefirst button 101 and thesecond button 103 are pressed.

设定第一按钮101按下时，主控制器驱动电机正转，第二按钮103按下时，主控制器驱动电机反转，两按钮同时按下，电机驱动推板12回到“0点”，即其行程中里U型支架8底板最近的点。It is set that when thefirst button 101 is pressed, the main controller drives the motor to rotate forward, and when thesecond button 103 is pressed, the main controller drives the motor to reverse, and when the two buttons are pressed at the same time, the motor drives thepush plate 12 to return to "0 point" ”, that is, the closest point to the bottom plate of theU-shaped bracket 8 in its travel.

本装置的使用方法为：How to use this device:

（1）接通电源，同时按下第一按钮101和第二按钮103，使推板12位置归零。(1) Turn on the power and press thefirst button 101 and thesecond button 103 at the same time to make the position of thepush plate 12 return to zero.

Open it, put theliquid storage bottle 5 into thepressurized chamber 2, pass the other end of theinfusion tube 603 through the threadedtube 4, and thethird connector 602 passes through the end of the threadedtube 4, as shown in FIG. 5, use Thelock 402 locks the third connectinghead 602 and the first connectinghead 401 at the end of the threadedpipe 4 , and covers the cover plate of the pressurizingchamber 2 .
