Description
Technical Field
The invention relates to the field of electric appliances of hair dryers, in particular to a cold and hot air mixed blowing hair dryer.
Background
The blower is composed of a group of electric heating wires and a high-speed small fan. When the fan is electrified, the heating wire can generate heat, and the air blown out by the fan passes through the heating wire and is changed into hot air. If only the small fan rotates and the heating wire is not hot, only wind but not heat is blown out. Traditional hair-dryer has cold wind and hot-blast switching function, and when the hair-dryer was in hot-blast shelves, the wind temperature that the hair-dryer blew off was high and dry, uses for a long time, causes the loss of hair moisture very easily, all can cause the thermal injury to hair and scalp. If the hair drier is switched to the cold air gear in order to protect the hair or avoid bad experience caused by overhigh wind temperature, the hair drying efficiency is too low.
The air duct device is particularly important in order to improve the blowing effect of the blower. In traditional wind channel device, only set up the main wind channel that can flow through high temperature fluid, and the air leads to the air outlet of hair-dryer somatic part front end from the air intake of hair-dryer somatic part rear end, this leads to the air to all gather through the impeller, therefore the impeller design is bigger, cause the noise big, required air output all flows through an wind channel, and the speed is very fast when passing through the heater strip, required heating wire is high-power, just can obtain hot-blastly, the thermal efficiency is poor, consume energy height, the air temperature through the heating of heating wire is high.
In addition, most conventional hair dryers are rear air intake type hair dryers, wherein a motor assembly of the hair dryer is located at the rear end of the body of the hair dryer and sucks air from the rear end, and the sucked air flows out of the body after being heated by a heating assembly at the front end of the body of the hair dryer or flows out of the body after passing through an additional air nozzle. By adopting the air inlet mode, due to the influence of the central motor component and the heating component, the central flow rate of air flow in the air blower is slow, the temperature is higher, and the defects that the experience of a user is poor, the service lives of the motor component and the heating component are influenced and the like are brought.
Therefore, the air duct and the air inlet mode in the air blower in the prior art are redesigned and researched, the air blowing efficiency can be further improved, and the user experience is improved.
