Referring to fig. 1, the intelligent hair growing device according to an embodiment of the invention includes a light emitting unit 400, a temperature and humidity sensing unit 600, and a processing unit 100. The intelligent hair growth device can be used for promoting hair growth by head, and can also be used for promoting hair growth by its part. The intelligent hair growing device is preferably applied to the head, and the irradiated part is the head or different parts in the head. The intelligent hair growing device is preferably an intelligent hair growing helmet, so that a user can dry other things, such as watching television, doing housework or working, while using the product, and the intelligent hair growing helmet is convenient for the user to use. The light emitting unit 400 is used for optically irradiating a user, and when the user wears the intelligent hair growing helmet of the present embodiment on his/her head and makes it work, the light emitting unit 400 emits light to irradiate the user's head (scalp). The operation modes of the light emitting unit 400 include a blinking state output mode and a normally-blinking state output mode, the blinking state output mode means that the light emitting unit 400 is alternately turned on and off during a certain period of time, and the two time allocations are controlled by the duty ratio. The normally-on state output mode means that the light emitting unit 400 is always on for a certain period of time. The light emitting unit 400 of the present embodiment is one or more of an LED, an edge-emitting laser diode, and a vertical cavity surface emitting laser diode. In order to make the effect better, the light emitting unit 400 is preferably a vertical cavity surface emitting laser diode, which generates laser light of one or more wavelengths from 630nm to 690nm, and more preferably, generates laser light of 655 nm. In order to illuminate a sufficient area, the number of the light emitting units 400 is preferably plural, for example, 40, 80, 200, etc., and the specific number can be determined by those skilled in the art according to actual requirements. The temperature and humidity sensing unit 600 is used for detecting the temperature and humidity of the irradiated portion (such as the head) of the user during the use process of the intelligent hair growing device, and particularly preferably, the temperature and humidity sensing unit 600 detects the temperature and humidity of the irradiated portion in real time during the operation process of the light emitting unit 400. In general, the temperature and humidity sensing unit 600 may measure temperature and humidity through infrared interfacing. However, in order to reduce interference and measurement accuracy, it is preferable in this embodiment that the temperature and humidity sensing unit 600 is in contact with the irradiated portion (or nearly in contact, i.e., the distance between the two is less than 5 mm), and measures the temperature and humidity thereof. The temperature and humidity sensing unit 600 in the embodiment of the invention is a DHT11 temperature and humidity sensor. The processing unit 100 may be an ECU or an MCU, and in this embodiment, the MCU is preferable. The processing unit 100 is connected to the light emitting unit 400 and the temperature and humidity sensing unit 600, and is configured to control the output power of the light emitting unit according to the detected temperature and/or calculate the oil and fat degree of the irradiated portion of the user according to the detected humidity, and particularly preferably, the processing unit 100 controls the output power of the light emitting unit and/or calculates the oil and fat degree of the irradiated portion according to the real-time collected temperature and humidity. The temperature and fat degree are measured by the temperature and humidity sensor, two important physiological parameters can be measured simultaneously, the volume occupation is reduced, and the difficulty that the fat degree sensor is large in volume and is not suitable for being placed in the intelligent hair growing device in the embodiment in the prior art is overcome. The temperature and humidity sensor is an innovation of the inventor, is a good compromise method, omits a large oil degree sensor in the prior art, calculates the oil degree through humidity, and meets the requirement of measuring the oil degree in a small space and meets certain oil degree measuring precision. When the temperature detected by the temperature and humidity sensing unit 600 is higher than a preset temperature T1 (for example, 40.2 degrees), the processing unit 100 controls the light emitting unit to reduce the output power; when the detected temperature is lower than a preset temperature T2 (for example, 37.8 degrees), the processing unit 100 controls the light emitting unit to increase the output power; when the detected temperature is between T2 and T1, the processing unit 100 controls the output power of the light emitting unit to be unchanged; wherein T2 is less than T1, preferably 37.6< T2<38.5, 39.8< T1<41.1, units, degrees Celsius. The processing unit 100 reduces the output power of the light emitting unit 400 by reducing the output duty ratio of the light emitting unit 400 or changing the light emitting unit 400 from a normally-bright state output to a blinking state output; the processing unit 100 achieves the increase of the output power of the light emitting unit 400 by increasing the output duty ratio of the light emitting unit 400 or changing the light emitting unit 400 from a blinking state output to a normally-on state output. The processing unit 100 calculates the degree of greasiness of the irradiated part based on the detected humidity and the ratio of water to grease in the secretion of the irradiated part. In the human body, the content of various components in the secretions of the respective epidermal tissues is mostly fixed, in particular, the ratio of water to oil in the scalp secretions. The moisture detected by the temperature and humidity sensor 600 can be used to determine the water content in scalp secretion, and the fat content can be determined by the ratio of water to fat, so that the fat degree can be determined. The accuracy of this greasiness does not become very high, but the need for hair loss treatment has been met.

In this embodiment, it is further preferable that the number of the temperature and humidity sensing units 600 is plural, and the temperature and humidity sensing units 600 are respectively disposed in different areas of the intelligent hair growing device, and one temperature and humidity sensing unit 600 detects the temperature and humidity of the irradiated part corresponding to one area; the processing unit 100 is configured to control the output power of the light emitting unit 400 of each region according to the detected temperature of the irradiated portion (different portion in the head) corresponding to the region and/or calculate the oil and fat degree of the irradiated portion according to the detected humidity of the irradiated portion corresponding to each region, for detailed description, please refer to embodiment two.

The temperature and humidity sensing unit is arranged on the intelligent hair growing device and is used for detecting the temperature and humidity of the irradiated part of a user in the use process of the intelligent hair growing device, and particularly preferably, the temperature and humidity sensing unit detects the temperature and humidity of the irradiated part in real time in the working process of the light emitting unit. In general, the temperature and humidity sensing unit may measure temperature and humidity through infrared indirect. However, in order to reduce interference and measurement accuracy, in this embodiment, it is preferable that the temperature and humidity sensing unit is in contact with the irradiated portion to measure the temperature and humidity thereof. The temperature and humidity sensing unit of the embodiment of the invention is a DHT11 temperature and humidity sensor.

Specifically, the output duty ratio of the light-emitting unit is reduced or the light-emitting unit is changed from a normally-bright state to a flashing state to be output, so that the light-emitting unit can reduce the output power; the output duty ratio of the light-emitting unit is increased, or the light-emitting unit is changed from the flashing state output to the normally-bright state output, so that the light-emitting unit can increase the output power. The oil degree is calculated according to the detected humidity and the ratio of water to oil in secretion of the irradiated part. In the human body, the content of various components in the secretions of the respective epidermal tissues is mostly fixed, in particular, the ratio of water to oil in the scalp secretions. The content of water in scalp secretion can be known by the detected humidity, and the fat content can be determined by the ratio of water to fat, so that the fat degree can be known. The accuracy of this greasiness does not become very high, but the need for hair loss treatment has been met.

Example two
Fig. 2 is a schematic structural diagram of an intelligent hair growing device according to a second embodiment of the present invention. Fig. 3 is a schematic view illustrating a bottom view of an intelligent hair growing device according to a second embodiment of the present invention. Referring to fig. 2 and 3, the intelligent hair growing device according to the embodiment of the invention is an intelligent hair growing helmet 6, which includes a processing unit 100, a storage unit 200, a first temperature sensing unit 300, a light emitting unit 400, a timing unit 500, a temperature and humidity sensing unit 600, and a circuit board (not shown). The circuit board is disposed within the intelligent hair growing helmet 6 for mounting the various units described above for providing power and communication thereto. The light emitting unit 400 is preferably the vcsel, and generally the relationship between the output power and the operating temperature of the vcsel when shipped is determined, which may be determined experimentally or provided by a vendor, which is referred to as a power-temperature curve. The power-temperature profile is stored in the memory unit 200 for convenient recall by the processing unit 100. The first temperature sensing unit 300 and the temperature and humidity sensing unit 600 are connected with the processing unit 100, the first temperature sensing unit 300 is used for detecting the temperature of the circuit board, the first temperature sensing unit 300 detects the temperature of the circuit board before the light emitting unit 400 works or after the light emitting unit 400 works for a certain time to send the temperature to the processing unit 100, and the processing unit 100 uses the temperature of the circuit board for calculation and storage, and stores the temperature in the storage unit 200.

The temperature and humidity sensing unit 600 is used for detecting the temperature and humidity of the irradiated portion (such as the head) of the user during the use process of the intelligent hair growing device, and particularly preferably, the temperature and humidity sensing unit 600 detects the temperature and humidity of the irradiated portion in real time during the operation process of the light emitting unit 400.
