Description

Technical Field

[0001] The utility model relates to the technical field of hair dryers, in particular to a hair dryer with intelligent temperature control. Background Art

[0002] A hair dryer is a commonly used small household appliance, which is mainly used for drying hair. Its working principle is that the heating wire in the hair dryer shell generates heat after being energized, and then the heat is blown out from the air outlet of the hair dryer by a fan to dry the hair. However, the air blown out by the hair dryer after being heated by the heating wire is relatively dry. When the air outlet is close to the skin, the hot air blown out by the hair dryer can easily burn the skin and the hair scales. In severe cases, it may even cause the hair to be burnt or even fall out. Therefore, it is urgent to develop a hair dryer that can intelligently control the temperature so that the hot air blown out of the air outlet is always kept within a comfortable temperature range. Utility Model Content

[0003] The utility model aims to provide a hair dryer with intelligent temperature control, which has the effects of intelligent temperature control, preventing scalding, and having both drying and hair care functions.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions: an intelligent temperature-controlled hair dryer, comprising a main body, the main body comprising a control system, a heating system, a first temperature sensor, a second temperature sensor and a third temperature sensor, the main body being provided with an air duct, an air inlet and an air outlet connected to the air duct, an air suction component being provided in the air duct, the air suction component driving an air flow into the air duct through the air inlet, so that the air flow entering the air duct is heated by the heating system and then blown out from the air outlet;

[0005] The first temperature sensor is used to detect the temperature of the air outlet, the second temperature sensor is used to detect the temperature of the air inlet, and the third temperature sensor is arranged on the air outlet surface and is used to detect the temperature of the human body surface; the control system is used to adjust the heating temperature of the heating system according to the detection temperature signals fed back by the first temperature sensor, the second temperature sensor and the third temperature sensor.

[0006] By adopting the above technical scheme, the air suction component draws the air flow into the air duct through the air inlet, and generates hot air under the heating of the heating system in the air duct. The hot air is blown out from the air outlet and used to dry the hair. When the hair dryer is working, the first temperature sensor, the second temperature sensor, and the third temperature sensor respectively detect the temperature of the air outlet, the air inlet and the hair or skin on the surface of the human body in real time. At the same time, the control system analyzes and compares the temperatures detected by the first temperature sensor, the second temperature sensor, and the third temperature sensor to determine the dryness or wetness of the hair or skin, so as to feedback control the heating system to increase, decrease or maintain the temperature, so that the temperature of the hot air blown out from the air outlet is always maintained within the range that makes the human body feel comfortable. The utility model can not only dry the hair, but also protect the hair, avoid damaging the hair scales, and achieve the purpose of making the hair soft, shiny and not losing moisture. It has the effects of intelligent temperature control, prevention of scalds, and both drying and hair care functions.

[0007] The utility model is further configured as follows: the air suction component includes a driving motor and a fan blade drivingly connected to an output end of the driving motor; the control system is electrically connected to the driving motor and is used to regulate the air output of the air outlet.

[0009] The utility model is further configured as follows: the main body is provided with an over-temperature alarm mechanism electrically connected to the control system.

[0010] By adopting the above technical solution, when the user uses the hair dryer too close to the hair or skin, the hot air blown out will cause the human skin or hair to heat up rapidly. At this time, the third temperature sensor is used to determine that the heating rate in this area is too fast, and feedback is used to control the over-temperature alarm mechanism to issue an alarm prompt to prevent burns to the human body.

[0011] The utility model is further configured as follows: the over-temperature alarm mechanism is configured as a display with a display reminder function.

[0016] By adopting the above technical solution, the air flow enters the exhaust channel through the air inlet, then flows into the annular channel through the exhaust channel and is blown out from the air outlet, thereby increasing the residence time of the air flow in the air duct and making the air blowing at the air outlet more uniform.

[0017] The utility model is further configured as follows: the annular channel includes a cyclone area away from the air outlet side and a heating area close to the air outlet side, the exhaust channel is connected to the cyclone area, the heating system is built into the heating area, and the other end of the heating area is connected to the air outlet.

[0018] By adopting the above-mentioned technical solution, when the airflow flows into the cyclone area through the exhaust channel, the cyclone area can guide the incoming airflow so that the airflow spirals around the annular channel to the heating area, thereby increasing the effective contact heating area between the heating system and the airflow, thereby improving the heating efficiency of the utility model.

[0019] The utility model is further configured as follows: the control system is configured as an MCU control system, the MCU control system includes a plurality of joint control units, one of the joint control units is arranged in the exhaust channel close to the air inlet, and the second temperature sensor is arranged on the joint control unit close to the air inlet side.

[0020] By adopting the above technical solution, the cooler airflow sucked into the exhaust channel from the air inlet can cool down the combined control unit. At the same time, the second temperature sensor is arranged on the combined control unit close to the air inlet side. The temperature influence factor is small, and the second temperature sensor can accurately record the surrounding ambient temperature.

[0021] The utility model is further configured as follows: the second temperature sensor is built into the cyclone area.

[0022] By adopting the above technical solution, since the cyclone area is located upstream of the heating system, the recorded air flow temperature is close to the ambient temperature and is used to measure the surrounding ambient temperature.

[0023] The utility model is further configured as follows: the heating system includes a bracket and a heating wire fixed on the bracket, and the first temperature sensor is fixedly connected to a side of the bracket close to the air outlet.

[0024] In summary, the utility model has the following beneficial effects:
