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.

Detailed Description

The present invention will be described in detail with reference to the following embodiments. The following examples will assist those skilled in the art in further understanding the present invention, but are not intended to limit the invention in any way. It should be noted that various changes and modifications can be made by one skilled in the art without departing from the spirit of the invention. These all belong to the protection scope of the present invention.

In the description of the present application, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing the present application and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application.

As shown in fig. 1 to 3, there is provided an automatic heat-dissipating blower including a handle 1 and a body 2, both provided with an air duct; the handle air duct comprises a handle main air duct and a handle auxiliary air duct which are not communicated with each other, and the body part air duct comprises a body part main air duct and a body part auxiliary air duct which are not communicated with each other; the handle main air duct is communicated with the body main air duct and can flow high-temperature fluid; the handle auxiliary air duct is communicated with the body auxiliary air duct and can flow low-temperature fluid; be provided with heating mechanism in the handle 1, heating mechanism includes heater strip 4 and heater strip support, heater strip support cover locates the outside of heater strip 4, heater strip 4 twines on a fixing base 3, set up the mounting groove on the fixing base 3, heater strip 4 twines layer upon layer along the fixing base mounting groove, and adjacent two-layer heater strip 4's minimum interval is more than or equal to 1.2mm, such design can make from the fluid of handle bottom entering can be abundant with every layer of contact of heater strip 4, thereby take away the heat on the heater strip 4.

Further, in order to avoid the poor experience of the user caused by the excessive diffusion of the heat of the heating wire to the handle shell, the radius of the fixing seat 3 is larger than that of the heating wire 4, so that the fixing seat 3 is in contact with the heating wire support, and the heating wire 4 is not in contact with the heating wire support. Preferably, a mica interlayer is arranged between the heating wire bracket and the heating wire 4, and similarly, the heating wire 4 is not contacted with the mica interlayer, and the fixed seat 3 is contacted with the mica interlayer, so that the heat of the heating wire can be further prevented from radiating to the outside of the handle of the hair drier. Preferably, the distance between the mica barrier and the heating wire 4 is 0.5 to 4 mm.

When the air-conditioner is used, air around the bottom and the side wall of the handle 1 enters the handle 1 through the air inlet arranged on the handle 1, a part of the air enters the heating mechanism arranged in the handle 1, is heated into high-temperature fluid, flows into the communicated body main air duct from the handle main air duct, and is finally blown out from the air outlet A of the body main air duct. Under the condition that the body part is also provided with the negative pressure air duct, the air outlet A of the main air duct of the body part blows out high-temperature fluid, negative pressure is formed at the position of the air outlet C of the negative pressure air duct, and air at the rear end of the body part 2 is promoted to flow through the negative pressure air duct and finally blown out from the position of the air outlet C of the negative pressure air duct.

After the other part of air enters the handle 1, the other part of air enters a handle auxiliary air channel formed by a gap between the heating mechanism and the handle 1 and enters a body part auxiliary air channel communicated with the handle auxiliary air channel, because the part of air is not heated by the heating wire 4, the temperature of the part of air is lower than that of high-temperature fluid, namely low-temperature fluid, the low-temperature fluid can cool components in the air blower and finally blow out the components from an air outlet B of the body part auxiliary air channel, because the air outlet B of the body part auxiliary air channel is circumferentially arranged around an air outlet A of the body part main air channel, and the air outlet A of the body part main air channel is circumferentially arranged around an air outlet C of the negative pressure air channel, the high-temperature fluid flowing out from the air outlet A of the body part main air channel, the low-temperature fluid flowing out from the air outlet B of the body part auxiliary air channel and the air flowing out from the air outlet C of the negative pressure air channel meet at the air outlet, and the air quantity is large according to the superposition effect, the temperature is mild, the scalp and the hair of a user can be well protected, and the user experience can be improved.

The foregoing description of the specific embodiments of the invention has been presented. It is to be understood that the invention is not limited to the specific embodiments described above. Various changes or modifications may be made by those skilled in the art within the scope of the claims without affecting the spirit of the invention. The embodiments and features of the embodiments of the present application may be combined with each other arbitrarily without conflict.
