Referring to fig. 2 and fig. 3 in combination, fig. 2 is a schematic circuit diagram of a power circuit, and fig. 2 is a schematic circuit diagram of a charge management circuit. Wherein 201 in fig. 2 is a charging interface (the charging interface 201 shown in fig. 2 is a TYPE-C interface) for connecting with an external power supply device, the Vusb interface in fig. 2 is an output terminal of a power supply circuit for connecting with the Vusb interface (an input terminal of a charging management circuit) in fig. 3, 301 in fig. 3 is a charging management chip, which may be of a TYPE TC4056A, and the Vbat-in interface in fig. 3 is an output terminal of the charging management circuit for connecting with a charging battery, it should be understood that the output terminal of the charging management circuit may also be directly connected with the controller 130 and the first terminal of the laser power supply control circuit 140, respectively.

It should also be appreciated that the power circuit shown in fig. 2 may vary when the charging interfaces are different; when the charging management chip is different, the peripheral circuit shown in fig. 3 may also be changed accordingly, which is not limited herein.

The first temperature collecting unit 130 may include a human body infrared temperature measuring module, a contact temperature measuring device, a temperature detecting sensor, etc., and may be set according to an application scenario and a requirement of the laser physiotherapy apparatus 100.

The laser power control circuit 140 may include one or more of resistors, capacitors, inductors, etc., as long as it can be used to provide the laser 110 with an operating voltage that matches the first temperature.

In an implementation manner, in order to make the working performance of the laser physiotherapy apparatus 100 better, the laser physiotherapy apparatus 100 further includes a controller 150, and the controller 150 is connected to the first temperature acquisition unit 130 and the laser power supply control circuit 140 respectively, and is configured to adjust a duty ratio of the PWM signal output to the laser power supply control circuit 140 according to the first temperature.

The controller 150 may include one or more processing cores. If the above-described laser therapy apparatus 100 is applied to an electronic device, the controller 150 may connect various parts within the entire electronic device using various interfaces and lines, perform various functions of the electronic device and process data by executing or executing instructions, programs, code sets, or instruction sets stored in a storage space thereof or an associated memory, and calling data stored in a storage space thereof or an associated memory. Alternatively, the controller 150 may be implemented in hardware using at least one of Digital Signal Processing (DSP), Field-Programmable Gate Array (FPGA), and Programmable Logic Array (PLA).

As an embodiment, the controller 150 may be a single chip microcomputer, as long as it can perform data processing and output a pulse width modulation signal.

It should be noted that the high-low level periods corresponding to the pwm signals corresponding to different operating parameters are the same (the same frequency) but the duty ratios are different. Therefore, when the laser 110 is controlled to operate according to the pulse width modulation signals corresponding to different operating parameters, the operating time of the laser 110 is different within the same time length range.

The frequency corresponding to the pwm signal may be, but not limited to, any one of 45KHz, 50KHz or 55KHz, etc., and the duty ratios of the pwm signals corresponding to different operating parameters are different, for example, may be any value between 0% and 99%.

Specifically, the controller 150 adjusts the duty cycle of the pwm signal according to the first temperature, thereby adjusting the output power of the laser 110. In the adjusting process, the first temperature can be obtained in real time to obtain the duty ratio of the pulse width modulation signal according to the first temperature, and the pulse width modulation signal corresponding to the duty ratio is output to the power supply control unit of the laser 110. The first temperature may also be obtained every preset time (e.g., 10 seconds, 30 seconds, or one minute, etc.), so as to obtain a duty ratio of the pwm signal according to the obtained first temperature, and output the pwm signal corresponding to the duty ratio to the power supply control unit of the laser 110.

When the user uses the laser therapy apparatus 100, since the skin surface temperature is low when the laser therapy apparatus 100 is just started to irradiate the skin surface of the user, the controller 150 may output the pulse width modulation signal with a higher duty ratio as shown in a graph a in fig. 4, so that the power of the laser 110 is higher, and the skin surface temperature of the human body is gradually increased as the usage time of the laser 110 increases, and the temperature of the corresponding laser 110 is also gradually increased, therefore, the controller 150 may adjust the pulse width modulation signal output by the controller 150 according to one or more of the usage time, the skin temperature of the human body, and the temperature of the laser 110, so that the controller 150 outputs the adjusted pulse width modulation signal as shown in a graph b in fig. 4, and it can be seen that the duty ratio of the pulse width modulation signal in a graph b in a graph in a is lower in the same high-low level period as that in b graph in fig. 4 is compared with a graph a, namely, the output power of the laser 110 is reduced by adjusting the working time of the laser in a high-low level signal period, so that the laser achieves the comfortable temperature of the human body.

By adopting the laser physiotherapy equipment 100, as the power of the laser 110 is large, and the laser wave band is in the red light or near infrared wave band, a certain heat effect is generated when the laser irradiates the skin of the user, so that the comprehensive physiotherapy effect of phototherapy heating moxibustion is achieved on the human body, and the experience of the user is improved; in addition, the output power of the laser 110 in unit time can be adjusted according to the temperature of the skin surface, so that the laser emitted by the laser 110 can prevent skin damage caused by overheating when the laser irradiates on a human body, and the safety of the laser physiotherapy equipment 100 is improved.

It should be noted that the power voltage control chip 142 is a chip for performing voltage and power conversion, and has low-input and high-output performance, that is, it is capable of performing a boosting process when a low-voltage signal is received at an input terminal thereof and then outputting a high-voltage signal through an output terminal thereof. The magnitude of the voltage of the output of the power voltage control chip 142 may also be determined according to the load connected to the output terminal thereof.

In this embodiment, the power supply voltage control chip 142 may be a chip with a model number of SGM3752, a chip with a model number of SGM3756, or a chip with a model number of SGM3751, which is not specifically limited in this embodiment, as long as it is a chip that can output a high voltage signal through its output terminal after performing a boosting process when receiving a low voltage signal at its input terminal.

The inductor L is used for boosting and storing energy for the power supply voltage control chip 142, and it should be understood that the inductor L shown in fig. 5 is only schematic and may be formed by connecting a plurality of coils in series, that is, the number of turns of the coil of the inductor L is not specifically limited here and may be set according to actual requirements.

By setting the diode D, the voltage and current output from the power supply voltage control chip 142 to the laser 110 can be effectively prevented from sudden change. Meanwhile, the inductor L may also provide a continuous current to the load through the diode D to further avoid abrupt change of the current voltage output to the laser 110, so the diode D may play a role of smoothing the current.

By arranging the first current limiting resistor R1, the current received by the feedback end of the power supply voltage control chip 142 can be small, so as to effectively avoid the problem that the feedback end of the power supply voltage control chip 142 is burnt out due to overlarge current when receiving a large current. Meanwhile, the output power of the laser 110 can be known, so that the laser power supply control circuit 140 outputs a current suitable for the operation of the laser 110.
