Description

hair dryer

technical field

The utility model relates to a hair drying and styling appliance, in particular to a hair dryer.

Background technique

In daily life, when people go to professional hair salons for haircuts and hairdressing, they need hair dryers; they also need it to dry their hair after bathing and shampooing at home. Hair dryers are widely used as a convenient and practical household appliance. However, the hair dryer is still a high-voltage live heating appliance, which is affected by various factors during use. If it is not used properly, it may cause electric shock and fire. A safer and more humanized hair dryer has become a higher pursuit of life for people.

Contents of the invention

The utility model aims at the above deficiencies, effectively combines the human body induction technology and the original function of the hair dryer, and realizes the intelligent control of hand-touch power-on work and hand-off power-off protection. The humanized design brings greater safety and protection to people's lives, and also adds fun.

The utility model is realized through the following schemes:

The utility model includes a casing, a machine cover, a motor, a motor seat, a fan blade, a heating wire, an air nozzle, a shift switch, an induction circuit, and an induction contact sheet, wherein the casing, the machine cover, the motor, the motor seat, and the fan blade The hot air duct system is composed of heating wire and air nozzle; the casing and cover are combined into a handle, and the built-in dial switch, sensing line, and sensing contact piece form a control system; the sensing line includes sensing elements, sensing springs, The induction spring is tightly pressed on the sensing contact, forming a sensing area on the sensing contact; one end of the sensing element is connected to a switch, and the human hand touches the sensing contact in the sensing area, and the sensing element controls the switch to be turned on; when the human hand leaves the sensing contact, the sensing The element control switch is open.

The utility model has the following advantages:

The concept is ingenious, the structure is compact, and the human body induction technology is used to control the power switch of the hair dryer, which effectively isolates the high-voltage and high-heat parts that have potential safety hazards, endows ordinary household appliances with technological elements, and effectively reduces accidents caused by improper operation. harm.

detailed description

Embodiment is described in detail below in conjunction with accompanying drawing:

As shown in Figure 1 and Figure 2, the hot air duct system composed of casing 5, machine cover 4, motor 9, motor seat 7, fan blade 8, heating wire 10, and air nozzle 11; casing 5, machine cover 4 Combined into a handle, the built-in dial switch 6, the induction circuit 3, and the induction contact piece 1 form a control system; the induction circuit 3 includes an induction element, an induction spring 2, and the induction spring 2 is pressed tightly on the induction contact piece 1. A sensing area 12 is formed on the sheet 1; one end of the sensing element is connected to a switch, and the human hand touches the sensing contact sheet 1 in the sensing area 12, the sensing element controls the switch to be turned on, and when the hand leaves the sensing contact sheet 1, the sensing element controls the switch to be turned off.

This device is ingenious in conception and compact in structure. It uses human body induction technology to control the power switch of the hair dryer, which effectively isolates the high-voltage and high-heat parts with potential safety hazards. It is a product worth promoting.
