In the actual use, in order to facilitate user's operation, rotate programmable impeller knob component SW1, the utility model discloses still give a therapeutic instrument equipment based on multifrequency pulse signal control, as shown in fig. 6 and 7, this equipment installation has this control circuit's control panel in shell 1 to install a connecting rod 3 on programmable impeller knob component SW1, connect in circular button 2 through this connecting rod 3, this circular button 2 is located 1 on the shell. The connecting rod 3 is used for connecting the programmable pulsator knob element SW1 and the circular rotary key 2. When the user operates, the operation of the programmable pulsator knob element SW1 can be realized by operating the circular rotation key 2. As can be seen from the figure, the housing 1 has only one circular rotary key 2, and the circular rotary key 2 is connected with the programmable pulsator knob element SW1 (i.e., reference numeral 4 in the figure) through the connection bar 3. There are not other unnecessary buttons on equipment shell 1, only a circular button for the outward appearance of equipment is more succinct, good-looking, has also significantly reduced the figure of the traditional button on the shell 1 simultaneously, and equipment volume diminishes.
The chip U1 detects and identifies the level signal generated in the circuit when the programmable rotary wheel element SW1 acts, and obtains a preset control instruction according to the parameter matching of the level signal, and then controls the working state of the corresponding equipment, the on-off, mode switching, signal intensity adjustment and control of the equipment according to the preset instruction. For example, when a user operates the programmable pulsator knob element SW1 through a circular rotary key to generate a corresponding level signal in the circuit, the chip U1 detects and identifies a parameter corresponding to the level signal, and correspondingly matches the parameter with a preset control instruction stored in the system, so as to identify the corresponding preset control instruction, and thus, the corresponding relationship between the action of the programmable pulsator knob element SW1 and the control of the device can be realized. For example, the up-down action, the left-right action and the like of the programmable rotary wheel element SW1 are used for realizing the control of the on-off, the mode switching, the signal intensity and the like of the equipment.

For example, when the programmable pulsator knob SW1 is pressed (i.e. the user presses the circular knob key to press the programmable pulsator knob SW 1), the pin 4 of the programmable pulsator knob SW1 is shorted to ground, and the pin 4 of the programmable pulsator knob SW1 is at a low level:
when the pin 8 of the chip U1 detects that the pin 4 of the programmable pulsator knob SW1 is at a low level and the time exceeds 1 second, the chip U1 is automatically started; if the chip U1 is in the on state, it is automatically powered off. That is, when the chip U1 is automatically powered on or off, the device controlled by the chip U1 is automatically powered off or on. When pin 8 of U1 detects that pin 4 of the programmable pulsator knob SW1 is low and the time is less than 1 second, the chip U1 automatically switches to the next mode. Chip U1 has 5 different modes in total and switches cyclically. Such as: when the programmable pulsator knob SW1 rotates clockwise, the pin 1 and the pin 3 of the programmable pulsator knob SW1 output square wave signals, and the pin 9 and the pin 10 of the chip U1 are increased by one step every time one square wave signal is detected. When the programmable pulsator knob SW1 rotates counterclockwise, the pin 1 and the pin 3 of the programmable pulsator knob SW1 output different square wave signals, and the pin 9 and the pin 10 of the chip U1 decrease the first shift strength every time a different square wave signal is detected.

That is to say: for example, the chip U1 is connected to the indicator light, and the chip U1 generates a corresponding control command according to the identified signal of the programmable pulsator knob SW1, controls the operation of the corresponding indicator light, and indicates the operation mode of the product.
As shown in fig. 4, the chip U1 is also connected to the PWM pulse intensity control circuit module through pins 13-12, and controls the pulse intensity output by the PWM pulse intensity control circuit module by outputting a corresponding control command to the PWM pulse intensity control circuit module.

Wherein the pulse amplification circuit is shown as 5.
That is, the parameters of the level signal corresponding to the action of the programmable pulsator knob SW1 are corresponded, and the corresponding preset control command is set and then stored in the system. The chip U1 detects and recognizes the level signal and matches the level signal to obtain a corresponding preset control instruction, so as to control the working state of the corresponding equipment, and realize the setting operation based on the control of the multi-pulse signal, such as long-press startup, long-press shutdown, short-press mode conversion, clockwise rotation to increase the pulse intensity, and counterclockwise rotation to decrease the pulse intensity.
