Referring to FIG. 4 and in conjunction with FIGS. 1 to 3 , a control method of a light wave therapy apparatus according to a specific embodiment of the present invention will be introduced. Among them, FIG. 4 is a main step diagram of a control method of a light wave therapeutic apparatus in an embodiment of the present invention.

As shown in Figure 4, the control method of the light wave therapy instrument includes:

Step S100, detecting the hair density of different parts of the head.

For example, when the user wears the light wave therapy device and turns it on, the controller controls the first radar sensor 31 , the second radar sensor 32 , the third radar sensor 33 and the fourth radar sensor 34 to detect the head and the first area, the second radar sensor 34 respectively. The hair density of the parts corresponding to the region, the third region and the fourth region. The controller can control the first radar sensor 31, the second radar sensor 32, the third radar sensor 33 and the fourth radar sensor 34 to detect the hair density of the corresponding part of the head once and use it as a control basis, and can also control the first radar sensor 31. The second radar sensor 32, the third radar sensor 33 and the fourth radar sensor 34 respectively detect the hair density of the corresponding parts of the head for multiple times, and average the hair density values detected multiple times as a control basis.

Step S200 , controlling the irradiation intensity of the weak laser light in the corresponding part according to the hair density of the different parts.

Specifically, step S200 further includes:

Step S210: Determine the irradiation intensity of the corresponding part according to the hair density of the different parts.

The irradiation intensity includes the density of the lit laser lamps in the corresponding area. The controller detects the parts of the head corresponding to the first area, the second area, the third area and the fourth area according to the first radar sensor 31 , the second radar sensor 32 , the third radar sensor 33 and the fourth radar sensor 34 . The hair density of , determines the density of the weak laser light 2 lit in the corresponding area. Specifically, for a specific area, according to the detected hair density corresponding to the area, the number of the weak laser lights 2 in the corresponding area is determined, and the greater the hair density of the corresponding part of the head and the area , the greater the number of weak laser lights 2 lit in the corresponding area, and the weak laser lights 2 lit in the area are evenly distributed in the area to ensure uniform illumination on the part of the head corresponding to the area. That is, the irradiation intensity of the weak laser light is controlled to be positively correlated with the detected hair density, so that the intensity of the weak laser light reaching different parts of the head is approximately the same.

Step S220, determining the irradiation duration according to the maximum value of the hair density in different parts.

For example, the mapping relationship between the hair density value and the irradiation duration is stored in advance. After obtaining the maximum value of the hair density in different parts, the controller searches for the irradiation duration corresponding to the density value from the preset relationship as the irradiation duration of the weak laser light. It can be understood that, in another feasible implementation manner, the controller can also receive a user's set duration parameter, so as to control the weak laser light to irradiate the corresponding duration. In another feasible implementation, the controller determines and controls the irradiation duration according to the maximum value of the hair density at different parts and the maximum irradiation intensity of the weak laser light at the corresponding part, that is, controls the weak laser corresponding to the part with the highest hair density in different parts The lamp is irradiated according to the maximum light intensity, and then the irradiation time is determined according to the required irradiation amount (which can be a preset fixed value) and the value of the hair density of the part, so that the part with the highest hair density is irradiated according to the strongest light, while The irradiation intensity of other parts adjusts the corresponding light intensity according to the proportional relationship between the corresponding hair density and the maximum density, thereby shortening the irradiation time and optimizing the user experience.

Step S230 , controlling the weak laser lights in different parts to irradiate the same duration of time according to the corresponding irradiation intensity.

The controller controls the corresponding weak laser lamps 2 in the corresponding area to be lit for the same duration according to the determined density of the weak laser lamps 2 lit in the corresponding area.

In another possible embodiment, the irradiation intensity includes the power of the weak laser light. The controller detects the parts of the head corresponding to the first area, the second area, the third area and the fourth area according to the first radar sensor 31 , the second radar sensor 32 , the third radar sensor 33 and the fourth radar sensor 34 . The hair density of , determines the power of the weak laser light 2 in the corresponding area. Specifically, for a specific area, the power of the weak laser light 2 in the corresponding area is determined according to the detected hair density corresponding to the area. The power of the weak laser light 2 in the area is larger. The controller controls the weak laser light 2 in the corresponding area to light up for the same duration according to the determined power of the weak laser light 2 in the corresponding area. The irradiation duration may be set by the user, or may be a built-in set irradiation duration.

Preferably, a plurality of first radar sensors 31 , a plurality of second radar sensors 32 , a plurality of third radar sensors 33 and a plurality of fourth radar sensors are arranged in the first area, the second area, the third area and the fourth area, respectively. 34. For a specific area, the hair density detected by multiple radar sensors can be averaged as the hair density of the part of the head corresponding to the area, so as to avoid the situation where there is a large error in the hair density detected by a single radar sensor , improving the detection accuracy, so as to control the irradiation amount of the weak laser light more accurately.

A plurality of first radar sensors 31 , a plurality of second radar sensors 32 , a plurality of third radar sensors 33 and a plurality of fourth radar sensors 34 are arranged in the first area, the second area, the third area and the fourth area, respectively. In this case, the controller can control the density and power of the weak laser light 2 lit in the corresponding area according to the hair density of different parts. For example, the controller controls the density of the weak laser lights 2 (that is, the number of lighted weak laser lights 2) in the corresponding area according to the average value of the hair densities detected by multiple radar sensors in a specific area, and at the same time according to the The hair density detected by different radar sensors in the area controls the power of the weak laser light 2 at the corresponding position. In this way, the irradiation amount of the weak laser light can be controlled more accurately, and the irradiation can be made more uniform.

In another feasible implementation manner, the radar sensors on the housing 1 are arranged in a one-to-one correspondence with the weak laser lights 2 . In this embodiment, there is no need to plan partitions for the inner lining 12 , and a radar sensor is provided at a position adjacent to each weak laser light 2 . The controller controls the power of the corresponding weak laser light 2 according to the hair density at the corresponding position of the head detected by each radar sensor. the uniform amount of radiation received by the unit. It can be understood that the controller can also control the irradiation duration of the corresponding weak laser light 2 according to the hair density at the corresponding position of the head detected by each radar sensor. The longer the irradiation time is, so that different parts of the head receive the same amount of irradiation. The controller can also control the irradiation power of the corresponding weak laser light 2 according to the hair density at the corresponding position of the head detected by each radar sensor. and exposure time.

With such an arrangement, the hair density detection accuracy of different parts of the head is more accurate, and the amount of radiation received by different parts of the head is more uniform.

In addition, the radar sensor in the above embodiment can also be replaced with an infrared temperature measuring sensor, and the controller is configured to determine the hair density of the corresponding part according to the temperature information detected by the infrared temperature measuring sensor of the corresponding part. Different hair density in different parts of the head will lead to differences in the rate of heat dissipation in different parts of the scalp, so the temperature of different parts of the scalp will also be different. The higher the density of hair, the slower the heat dissipation of the scalp, and the higher the temperature. Therefore, the controller can determine the hair density of the corresponding part according to the temperature information detected by the infrared temperature sensor of the corresponding part, and then control the irradiation intensity of the weak laser light.

Those skilled in the art can also understand that, in the above embodiment, the sensor is arranged on the lining 12 is also a specific arrangement, and those skilled in the art can adjust it as needed, for example, the sensor can also be arranged on the circuit Positions on the plate corresponding to the openings on the lining 12 . In addition, the shell 1 includes an outer shell 11 and an inner lining 12, which is also a specific setting method, and those skilled in the art can adjust it as needed.

A plurality of sensors for hair density, the controller is connected with a plurality of weak laser lights and a plurality of sensors, and is used to control the irradiation intensity of the weak laser lights in the corresponding parts according to the hair density of different parts of the head detected by the plurality of sensors, The irradiation intensity of the weak laser light is controlled to be positively correlated with the detected hair density, so that the intensity of the weak laser light reaching different parts of the head is roughly the same, so that different parts of the head receive the same amount of weak laser irradiation, avoiding the need for different users. Different hair densities and different hair densities in different parts of the head lead to uneven irradiation, which ensures uniform irradiation and good physiotherapy effects.
