Description

Infrared hair dryer

The novel is a hair dryer, especially an infrared hair dryer.

The hair dryer is one of the most frequently used household appliances in daily life, and the general function is to generate hot air to dry the wet hair. A hair dryer generally includes a casing, a fan, a motor, and a heating wire module, wherein the casing has an inner space, and the casing has an inlet opening and an outlet opening respectively formed at opposite ends. The fan, the motor and the heating wire module are housed in an inner space of the outer casing, the fan is disposed on a side close to the air inlet opening, and the motor is connected to the fan to drive the fan to rotate to generate an air flow. Air is drawn into the internal space by the air inlet opening, and the air outlet is discharged from the internal space. The heating wire module is disposed between the fan and the air outlet opening, so that the airflow can flow through the heating wire module to heat the air in the airflow to form a high temperature airflow. In this way, the hair dryer can blow hot air for the user to dry the wet hair.

However, the general hair dryer is to dry the hair by generating hot air. If the user wants to dry the hair as soon as possible, the heating power of the heating wire module is generally increased to increase the temperature of the hot air. However, when the heating power of the heating wire module is high, the temperature of the hot air generated is also high. If the hot air is blown to the same part for a long time, the hair or the scalp may be burnt. In addition, although the high-temperature hot air blown by the blower can dry the hair, the high-temperature hot air may take away excess water in the hair and scalp hair follicle cells, causing the user to blow dry hair and hair follicle cells of the scalp. Dry damage. Therefore, the existing hair dryer must be further improved.

Since the existing hair dryer technology provides a high temperature hot air to dry the hair, when the user raises the temperature of the high temperature hot air to increase the speed of the dry hair, the high temperature hot air may cause hair or skin burns, and easily take away hair and scalp cells. The moisture contained therein causes the hair to be dry and the scalp cells to dry. Therefore, the present invention provides an infrared hair dryer. The infrared hair dryer comprises a casing, a power module, a fan device, an electric heating device and an infrared module. The outer casing is formed with an inner space, and the outer casing has a blowing portion and a holding portion. The opposite ends of the blowing portion respectively form an air inlet opening and an air outlet opening. The power module is disposed in the internal space and has a wire for supplying power to an external power source. The power module is electrically connected to the fan device, the electric heating device and the infrared module to obtain power from the external power source, and The fan device, the electric heating device and the infrared module are electrically driven. The fan device is disposed in the inner space and is located between the air inlet opening and the air outlet opening and adjacent to the air inlet opening. The infrared module is disposed in the inner space between the fan device and the air outlet opening and adjacent to the air outlet opening.

The infrared module provides an infrared light source. When the user activates the infrared blower, the infrared blower can simultaneously illuminate the infrared light source to the user's hair and scalp in addition to the hot air. Since infrared light belongs to electromagnetic waves with a long wavelength and has low energy, it provides a gentle radiation heat energy and accelerates hair drying. Therefore, it can prevent the excessive temperature of hot air from taking away excessive moisture of hair and scalp cells, so that wet hair is It will remain smooth after drying. Further, the infrared rays can increase the blood circulation of the subcutaneous microvessels after being irradiated to the skin, thereby activating the scalp hair follicle cells, making the hair and scalp healthier.

Referring to FIG. 1 and FIG. 2 , the infrared blower comprises a housing 10 , a power module 11 , a fan device 12 , an electric heating device 13 and an infrared module 14 . The outer casing 10 is formed with an inner space 100 and has a blowing portion 101 and a holding portion 102. The opposite ends of the blowing portion 101 respectively form an air inlet opening 103 and an air outlet opening 104. The opening 103 and the outlet opening 104 communicate with the internal space 100, respectively.

The power module 11 obtains power from the external power source and provides electric power to drive the fan device 12, the electric heating device 13 and the infrared module 14.

The fan unit 12 rotates and pushes air to generate a flow of air from the inlet opening 103 to the outlet opening 104. Since the electric heating device 13 is energized and generates a high temperature, when the airflow generated by the fan device 12 passes through the electric heating device 13, the airflow generated by the fan device 12 is heated to generate a high-temperature airflow to be blown out from the air outlet opening 104. The infrared module 14 generates an infrared light source that is outwardly illuminated by the air outlet opening 104. Preferably, the infrared module 14 is provided with a halogen lamp coil. The fan device 12 generally includes a fan 121 and a motor 122. The motor 122 is electrically connected to the power module 11 and connected to the fan 121. The fan 121 is driven to rotate. In general, the motor 122 can be selected from a DC motor.

The infrared module 14 provides an infrared light source that is incident on the user's hair and scalp when the user activates the hair dryer. Since infrared light belongs to electromagnetic waves with a long wavelength and has a low energy, it provides a gentle radiation heat energy to accelerate hair drying. Therefore, it can prevent hair and scalp from being burnt by the high temperature airflow for a long time, causing burns on the hair or scalp, and avoiding the high temperature airflow to take away excess water of the hair and scalp cells, so that the user's wet hair can still keep smooth after drying. Further, the infrared rays can increase the blood circulation of the subcutaneous microvessels after being irradiated to the skin, thereby activating the scalp hair follicle cells, making the hair and scalp healthier.
