Description

The utility model belongs to a far infrared device.

Existing far-infrared hair dryer is mainly made up of heating wire, near-heating type far-infrared radiation element, rectifier diode, motor, fan blade, and its structure will be used as heat source heating wire around as support near-heating type far-infrared heating element. on the radiating element. When the power is turned on, the electric heating wire as a heat source generates high temperature, which indirectly causes the heating far-infrared radiation element to generate far-infrared rays, and the motor rotates to drive the fan blades to send hot air through and heat the heating-type far-infrared radiation at the air outlet. The element is blown onto the human head to dry hair. Because the far-infrared hair dryer with this structure mainly uses the electric heating wire as the heat source, the temperature of the hot air blown out is high (the temperature of the air outlet reaches 100°C), which is easy to damage the hair and consumes a lot of power. The far-infrared rays radiated by the radiation element do not directly radiate to the head of the human body, and cannot play the role of far-infrared rays to dry hair. The far-infrared ray produced by the heat-type far-infrared radiating element at the air outlet heated by the hot air is weak, and the infrared ray has little drying effect. Therefore, the far-infrared hair dryer mainly relies on the hot air blown out to dry hair.

The utility model provides a far-infrared physiotherapy hair dryer which directly uses far-infrared rays to dry hair and has physiotherapy effect.

The far-infrared physiotherapy hair dryer provided by the utility model is mainly composed of a direct-heating far-infrared radiation element, a rectifier diode, a motor, and fan blades. When the power is turned on, the direct heating far-infrared radiation element is heated through the rectification diode, and the strong far-infrared radiation radiates directly to the head of the human body, playing the role of physical therapy and hair drying. At the same time, the rotation of the motor drives the fan blades to blow air to the head of the human body, which plays an auxiliary role in accelerating the evaporation of hair moisture and speeding up the hair drying process. Because the far-infrared physiotherapy hair dryer with this structure directly uses far-infrared rays to dry the hair, the temperature generated is relatively low (the temperature at the air outlet is about 60°C), which will not damage the hair cells, and can promote the blood circulation of the human scalp. It has the physiotherapy function of disinfection and sterilization, and saves more than 50% of electricity than ordinary hair dryers.

Compared with the prior art, the utility model has the advantages of fast hair drying speed, no hair damage, physical therapy effect of promoting blood circulation of human hair, disinfection and sterilization, power saving and the like.

Figure 1 is a sectional structure diagram of a far-infrared physiotherapy hair dryer, [1] is the shell, [2] is the air outlet, [3] is the direct heating far-infrared radiation element, [4] is the fixing screw, and [5] is the fixing Support, [6] is a motor, [7] is a fan blade, and [8] is a combined control switch.

Figure 2 is the electrical schematic diagram of the far-infrared physiotherapy hair dryer, [3] is the direct heating far-infrared radiation element, [6] is the motor, [8] is the combination control switch, [9], [10] are the rectifier diode V ₁ V ₂ .

Describe in detail below in conjunction with accompanying drawing.

The direct-heating far-infrared radiation element [3] is fastened on the fixed bracket [5] with the set screw [4], the fixed bracket [5] is connected with the motor [6], and the fan blade [7] is fixed on the motor shaft.

When the K ₁ and K ₂ of the combination control switch [8] are closed, the power is turned on, and through the rectifier diodes V ₁ [9], V ₂ [10], the direct heating far-infrared radiation element [3] plus full Wave voltage generates strong far-infrared rays (the temperature at the air outlet [2] is about 60°C), which radiates directly to the head of the human body, drying hair and providing physical therapy. At the same time, the rotation of the motor [6] drives the fan blades [7] to blow air to the head of the human body, so as to speed up the process of hair moisture evaporation and hair drying. If K ₁ of the combination control switch [8] is on and K ₂ is on, through the rectifier diode V ₂ [10], a half-wave voltage is added to the direct-heating far-infrared radiation element [3], and the power consumption is only full-wave voltage 1/4 of the time, strong far-infrared rays are produced (the temperature at the air outlet [2] is about 45°C), which radiates to the head of the human body, drying the hair and providing physical therapy. Simultaneously, the rotation of the motor [6] drives the fan blade [7] to blow air, which accelerates the process of hair moisture volatilization and hair drying. If K ₁ of combined control switch [8] is closed and K ₂ is opened, the motor [6] and fan blade [7] do not turn, and the rectifier diode V ₁ [9] is heated by the direct heating far-infrared radiating element [3]. The upper half-wave voltage produces strong far-infrared radiation (the temperature at the air outlet [2] is about 45°C), which is suitable for physical therapy of other parts of the human body.
