[0002] Red light therapy device is a commonly used medical phototherapy device in clinical medicine. Its basic principle is to obtain red visible light mainly in the range of 600-760nm through a special filter. It is called red light because the retina's light perception is red. It has thermal and photochemical effects, and can effectively penetrate human tissue to a depth of about 30mm. It can promote the body's cellular enzyme reactions, increase aerobic respiration function, activate multiple enzymes, and promote cell metabolism. Other bands of light waves cannot reach this, so its biological effects are more direct and obvious.

[0003] The existing red light therapy devices do not have equipment or instruments for the recovery of private internal soft tissues and relief of pain for postpartum women. In addition, the existing maintenance rods have poor temperature control accuracy, which can easily lead to problems such as product temperatures frequently exceeding the threshold and causing alarms. Summary of the invention

[0004] The first purpose of the present invention is to provide a temperature control method for a red light therapy device, which aims to solve the technical problem that the temperature control accuracy of existing phototherapy equipment is poor, which may lead to the product temperature frequently exceeding the threshold and causing an alarm due to insufficient temperature control accuracy.

[0055] Embodiment 1:

[0056] Please refer to Figure 1-Figure 11The embodiment of the present invention provides a red light therapy device 100, including a host 110 and a therapy stick 120. The host 110 includes a main control board 111; the therapy stick 120 includes a handle control unit 121 and a red light therapy unit 122, the handle control unit 121 includes a circuit board 1211 and a cooling fan 1212, the circuit board 1211 is electrically connected to the main control board 111, the red light therapy unit 122 includes a heating body 1221 and a transparent cylinder 1222, the transparent cylinder 1222 has a first end 1222A and a second end, the first end 1222A of the transparent cylinder 1222 is connected to the handle control unit 121, the heating body 1221 is disposed in the transparent cylinder 1222, and the heating body 1221 includes a mounting component 1221 A and a heating unit 1221B, the heating unit 1221B is connected to the mounting component 1221A, the heating unit 1221B is electrically connected to the circuit board 1211, the mounting component 1221A includes a heat dissipation channel 1221C, the heat dissipation fan 1212 is connected to the heat dissipation channel 1221C, the heating unit 1221B includes a plurality of first temperature sensors 1205 and a plurality of lamp beads 1207, the plurality of first temperature sensors 1205 are spirally distributed along the direction from the first end 1222A to the second end, and a second temperature sensor 1206 is arranged at the end of the mounting component 1221A and near the second end. Exemplarily, the mounting component 1221A is columnar, and a plurality of lamp beads 1207 are evenly and spacedly distributed on the mounting component 1221A, and the lamp beads 1207 are used to emit infrared light to increase the temperature of the transparent cylinder 1222. The transparent cylinder 1222 is made of transparent material, and can allow the red light emitted by the lamp beads 1207 to pass through. In this embodiment, six first temperature sensors 1205 and one second temperature sensor 1206 are provided, that is, a total of seven temperature sensors are provided in the treatment rod 120 of the present application. By providing temperature sensors at multiple locations to detect real-time temperature, local high temperature is avoided and the accuracy of temperature detection is improved. Since six heating units 1221B are provided in the treatment rod 120 of the present application, and the heating units 1221B are enclosed to form a regular hexagonal arrangement. Since the light emitted by the lamp beads 1207 is divergent outward, the temperature of the parts between adjacent heating units 1221B will be lower, which may cause local high temperature. Therefore, the present application distributes multiple first temperature sensors 1205 in a spiral shape, so that multiple first temperature sensors 1205 and second temperature sensors 1206 are distributed at various locations, and temperature data of multiple locations can be obtained, thereby improving the accuracy of temperature detection.

[0057] A plurality of first temperature sensors 1205 distributed in a spiral shape are an important inventive point of the present invention. When the first temperature sensors are actually arranged, the conventional scheme is a matrix-type uniform distribution to obtain a uniform temperature monitoring result. However, in the present case, the first temperature sensors are arranged on the outside of the heating unit 1221B of the treatment rod 120 which is enclosed in a regular hexagon. The conventional matrix-type uniformly distributed sensor arrangement will set one or more first temperature sensors at the corresponding position of each heating unit 1221B, which results in too many first temperature sensors being set. However, the present application takes into account that the positions with high temperature are regular, and the specific projection to the corresponding positions of the heating unit 1221B enclosed in a regular hexagon of the present scheme is less than 6, and the positions with high temperature are prone to form points similar to the spiral distribution. Therefore, the present application adopts a plurality of first temperature sensors distributed in a spiral shape corresponding to the local high temperature positions, which not only achieves a reduction in the number of temperature sensors, but also takes into account the cross-distribution of a plurality of first temperature sensors 1205 to obtain temperature data at a plurality of positions, thereby improving the accuracy of temperature detection. In addition, a second temperature sensor 1206 is provided at the end of the mounting component 1221A away from the handle control unit 121 to obtain temperature data of the top portion of the mounting component 1221A, and cooperates with multiple first temperature sensors 1205 to further improve the accuracy of temperature detection.

[0058] Please refer to Figure 3 , Figure 5 , Figure 7 In this embodiment, the red light therapy device 100 of the present application is provided with a second temperature sensor 1206 and multiple first temperature sensors 1205, and the multiple first temperature sensors 1205 are spirally distributed along the axial direction of the mounting component 1221A, and the second temperature sensor 1206 is arranged at the front end position of the mounting component 1221A. That is to say, the temperature sensors are distributed at various positions in the transparent cylinder 1222, which is beneficial to improving the accuracy of temperature detection and expanding the detection range, and avoiding local high temperature in the red light therapy part 122.

[0059] In this embodiment, the temperature range between 30°C and 50°C is the temperature range of the red light therapy unit 122 during normal treatment. When the temperature of the red light therapy unit 122 has not reached the first temperature level, the lamp bead 1207 operates at a higher power, causing the red light therapy unit 122 to heat up quickly. When the temperature exceeds the first temperature level but does not exceed the first temperature threshold, the lamp bead 1207 will operate at a lower power. Due to the detection delay of the temperature sensor, if the temperature rises too quickly, the red light therapy device 100 will easily exceed the operating temperature. In addition, by setting the temperature difference threshold, the temperature difference of each area in the red light therapy unit 122 is controlled, further limiting the red light therapy unit 122 from heating up too quickly, causing the actual temperature to be out of control and exceeding the first temperature threshold.

[0060] In another embodiment, by providing a heat dissipation fan 1212 and a heat dissipation channel 1221C, when the temperature in the red light therapy part 122 is too high or there is a large local temperature difference, the heat dissipation fan 1212 is turned on to discharge part of the heat from the heat dissipation channel 1221C, so as to achieve the effect of lowering or balancing the temperature in the red light therapy part 122.

[0061] Please refer to Fig.11 The temperature control method of the red light therapy device 100 includes:

[0062] The first temperature threshold, the first gear temperature, the second gear temperature, the third gear temperature, the temperature difference threshold and the temperature rise rate threshold are preset, wherein the first gear temperature, the second gear temperature, the third gear temperature and the first temperature threshold are increased in sequence; illustratively, the first temperature threshold is 50°C, the first gear temperature range is greater than or equal to 30°C and less than 37°C, the second gear temperature range is greater than or equal to 37°C and less than 43°C, and the third gear temperature range is greater than or equal to 43°C and less than 49°C. The first gear temperature, the second gear temperature and the third gear temperature are all the operating temperatures of the red light therapy device 100.

[0063] Get the target gear temperature;

[0064] The second temperature sensor 1206 and the plurality of first temperature sensors 1205 acquire current temperature values, and the plurality of current temperature values ​​constitute a current temperature set;

[0065] Calculate the current temperature average of multiple current temperature values ​​in the current temperature set, select the current maximum temperature value and the current minimum temperature value from the current temperature set and calculate the current temperature difference value;

[0066] If the current temperature average is lower than the first-level temperature, the lamp bead 1207 works at a fast heating power; if the current temperature average is not lower than the first-level temperature, the current temperature average and the target level temperature are compared, and the lamp bead 1207 and the cooling fan 1212 are controlled to work according to the comparison result; if the current temperature average exceeds the first temperature threshold, or the current temperature difference exceeds the temperature difference threshold, the cooling fan 1212 is controlled to start working; exemplarily, it can be understood that when the temperature in the red light therapy part 122 does not exceed 30°C, the lamp bead 1207 works at a higher power to make the red light therapy part 122 heat up quickly and reduce the waiting time for the user. When the temperature in the red light therapy part 122 is in the range of 30°C to 50°C, this temperature range is the treatment temperature range. Therefore, the present application controls the heating speed and temperature difference within this temperature range to avoid excessive heating or local high temperature, which may cause damage to the soft tissue of the female vagina and improve the user experience. It should be noted that since the vaginal soft tissue of postpartum women is very fragile and sensitive, the red light therapy device 100 of the present application controls its heating rate and temperature difference range to minimize the stimulation of the therapy device to the vaginal soft tissue of postpartum women while giving users a comfortable experience.

[0067] Among them, controlling the lamp beads 1207 and the cooling fan 1212 to work according to the comparison result includes:

[0068] If the current temperature average and the target gear temperature are both within the same gear temperature range, the lamp beads 1207 are controlled to work at the first power, and the cooling fan 1212 is controlled to work at the second power; the situation at this time includes that the current temperature average and the target gear temperature are both within the first gear temperature range, or both within the second gear temperature range, or both within the third gear temperature range. At this time, it is required that the temperature in the red light therapy unit 122 can be kept basically unchanged when the lamp beads 1207 work at the first power and the cooling fan 1212 work at the second power.

[0069] If the current temperature mean and the target gear temperature are within the adjacent gear temperature range, and the current temperature mean is less than the target gear temperature, the lamp bead 1207 is controlled to work at the first power, and the cooling fan 1212 is controlled not to work; the situation at this time includes that the current temperature mean is within the first gear temperature range, the target gear temperature is within the second gear temperature range, or the current temperature mean is within the second gear temperature range, and the target gear temperature is within the third gear temperature range. At this time, since the gear temperatures are similar, the lamp bead 1207 is controlled to work at a smaller first power, so as to control the temperature in the red light therapy unit 122 to rise slowly. In addition, it should be noted that the first temperature sensor 1205 and the second temperature sensor 1206 are detected in real time. If the current temperature mean rises to the gear temperature range with the same target gear temperature, the lamp bead 1207 is controlled to work at the first power, and the cooling fan 1212 is controlled to work at the second power.

[0070] If the current temperature average and the target gear temperature are within the adjacent gear temperature range, and the current temperature average is greater than the target gear temperature, the cooling fan 1212 is controlled to start working; the current temperature average is within the second gear temperature range, the target gear temperature is within the first gear temperature range, or the current temperature average is within the third gear temperature range, and the target gear temperature is within the second gear temperature range. At this time, the cooling fan 1212 is turned on to cool down.

[0071] If the current temperature average and the target gear temperature are within non-adjacent and different gear temperature ranges, and the current temperature average is lower than the target gear temperature, the lamp bead 1207 is controlled to work at the third power first and then at the first power, the cooling fan 1212 is controlled not to work, and the third power is greater than the first power; the situation at this time includes that the current temperature average is within the first gear temperature range, and the target gear temperature is within the third gear temperature range. At this time, due to the large difference between the current temperature average and the target gear temperature, when the first gear temperature rises to the second gear temperature, it will heat up at a larger heating rate, that is, at the third power, and when the second gear temperature rises to the third gear temperature, it will heat up at a smaller heating rate, that is, at the first power.

[0072] If the current temperature mean and the target gear temperature are located in non-adjacent and different gear temperature ranges, and the current temperature mean is greater than the target gear temperature, the cooling fan 1212 is controlled to work at the fourth power first, and then at the second power, and the fourth power is greater than the second power. The situation at this time includes that the current temperature mean is within the third gear temperature range, and the target gear temperature is within the first gear temperature range. At this time, due to the large difference between the current temperature mean and the target gear temperature, when the third gear temperature drops to the second gear temperature, it will cool down at a larger cooling rate, that is, at the fourth power, and when the second gear temperature drops to the first gear temperature, it will cool down at a smaller cooling rate, that is, at the fourth power. Through the above-mentioned temperature control method, when the temperature difference between the current temperature mean and the target gear temperature is not too large, the red light therapy part 122 is controlled to change the temperature at a smaller heating or cooling rate, and when the temperature difference between the current temperature mean and the target gear temperature is large, the red light therapy part 122 is controlled to heat up or cool down at a larger rate, and then heat up or cool down at a smaller rate. It can achieve the goal of quickly adjusting the temperature level required by the user while preventing the temperature from changing too quickly and causing the temperature to lose control. Especially when approaching the first temperature threshold, it is easy for the actual temperature to exceed the first temperature threshold, but the detected temperature feedback is still within the operating temperature range. In this case, the temperature of the red light therapy device 100 cannot be adjusted in time.

[0073] Please refer to Figure 8 , Fig. 9 , Fig.10 In a possible implementation, the first temperature sensor 1205 and the second temperature sensor 1206 obtain a current temperature set once every bit time; the last temperature mean is calculated based on the last collected temperature set, and the current temperature change rate is calculated based on the last temperature mean and the current temperature mean; if the current temperature change value exceeds the heating rate threshold, the cooling fan 1212 is controlled to start working and / or the lamp bead 1207 is controlled to reduce the output power.

[0074] Please refer to Figure 8 , Fig. 9 , Fig.10In a possible implementation, the red light therapy device 100 of the present application is used to implement the above-mentioned temperature control method, and the host 110 also includes a display 112, which is electrically connected to the main control board 111, and a third temperature threshold and a fourth temperature threshold are preset. When the maximum temperature value exceeds the third temperature threshold, the control board controls the display 112 to issue an alarm message, and when the maximum temperature value exceeds the fourth temperature threshold, the control board controls the lamp bead 1207 to stop working, and the values ​​of the first temperature threshold, the third temperature threshold, and the fourth temperature threshold increase in sequence. Exemplarily, in this embodiment, the third temperature threshold is 55°C and the fourth temperature threshold is 60°C. The display 112 can display data during use, including temperatures corresponding to different time periods, use operation time, etc. A temperature control switch is also included between the circuit board 1211 and the lamp bead 1207. When the temperature exceeds the fourth temperature threshold, the lamp bead 1207 is controlled to stop working by the temperature control switch.

[0075] Please refer to Figure 8 , Fig. 9 , Fig.10 In a possible implementation, if the current temperature average exceeds the first temperature threshold and does not exceed the third temperature threshold, the cooling fan 1212 is controlled to start working, and the lamp bead 1207 works at the fifth power;

[0076] If the current temperature difference exceeds the temperature difference threshold within the range of the first temperature threshold to the third temperature threshold, the cooling fan 1212 is controlled to start working. For example, if the current temperature average is within the range of 50°C to 55°C, the lamp bead 1207 works at the third power, and the cooling fan 1212 is turned on to keep the temperature within a substantially constant range. If the current temperature average is within the range of 30°C to 55°C, the treatment stick 120 is in use, which may cause damage to the vaginal soft tissue. Therefore, the temperature difference range needs to be controlled within this temperature range. However, before 30°C, the user will not use it, and even if it is used, the stimulation to the vaginal soft tissue is relatively small, so the temperature difference range is not controlled before 30°C.

[0097] First, plug in and connect the host 110 and the treatment stick 120, obtain a clean and sterilized treatment stick 120, and put a sterilized film cover on the transparent cylinder 1222 to play a sterilization and protection role.

[0098] Secondly, turn on the host 110, turn on the connected treatment stick 120 to conduct data parameter transmission, and preheat for a period of time, for example, 3 minutes, before the first practical operation, so that the transparent tube of the treatment stick 120 feels warm, and then slowly put the transparent tube 1222 of the treatment stick 120 into the vagina of the parturient.

[0099] On the one hand, the temperature sensor can always obtain the real-time temperature in the transparent cylinder and feed it back to the circuit board 1211.

When the temperature in the transparent cylinder 1222 drops to a reasonable use range temperature (30-50 degrees), the display 112 of the host 110 will display the operation prompt instructions.
