Abstract

A heat insulated hair dryer. The hair dryer comprises a first casing (1) and a second casing (2), both of which can be configured to be opened or closed. The first casing (1) and the second casing (2) are closed to form a cavity; an air inlet hole (3) is formed in the first casing (1), and a wind power mechanism for generating wind in the cavity is disposed within the first casing; working faces of the first casing (1) and the second casing (2) are a first working face (7) and a second working face (8) respectively; at least one air outlet hole (9) is formed in the first working face (8). Wind coming out of a blower forms a circulation in the first casing (1) and the second casing (2) by means of a sealed cavity formed after the first casing (1) and the second casing (2) are closed, thereby avoiding waste caused by the leakage of heat.

It does not meet the technical development trend of the hair dryer industry, and the blow-out type of hair dryer will cause heat. Give way.

[0003] Chinese patent CN 104188314 B discloses a circulating hair dryer, which is proposed to include a hollow pipe, the hollow pipe is provided with a hand-held portion, and the two ends of the hollow pipe are bent to form a relatively arranged pipe mouth. A space for accommodating hair is disposed between the pipe mouths, and a hot air device is disposed at any one of the hollow pipes. The air outlet of the present invention is disposed opposite to the air inlet, and the air blowing device or the air suction device is used for recycling. The two ducts of the circulating blower are empty in the middle and are directly exposed to the outside, which may cause heat leakage from the hot air device.

Embodiments of the invention

[0016] The embodiments of the present invention are further described below with reference to the accompanying drawings:

[0017] In the present invention, the hinged portion of the first housing and the second housing is an integral left side, and the air inlet hole is disposed on the right side of the first housing, the same as the first housing and the second The housings are interchangeable, and the side of the vane adjacent to the air inlet is the outer side, and the other side of the vane is the inner side, and the left side of the use surface is the position away from the air inlet.

[0018] As shown in FIGS. 1 and 2, the present invention provides an insulated blower comprising a first housing and a second housing, both of which can be opened or closed, ie, the first housing One end of 1 is hingedly disposed with one end of the second casing 2, and the two can be closed or opened around the hinge shaft, and the air inlet hole 3 is provided in any one of the casings, and is disposed in the casing provided with the air inlet hole 3 a wind mechanism for generating wind in the cavity, the wind mechanism may be a blowing mechanism or a vacuum suction mechanism, wherein the blowing mechanism comprises a blade 4, a driving motor 5 and a heating assembly 6, and the blade 4 is close to the air inlet The hole 3 is disposed, the fan blade 4 is rotated by the driving motor 5, and the rotation of the blade 4 causes the external air to enter from the air inlet hole, thereby being driven by the fan blade 4 to move inward and through the heating assembly 6, The heating unit 6 performs heating, and a control button can be provided on the housing for controlling the operation of the driving motor and the heating unit, and the hot air and normal air selecting gear positions can also be set. [0019] As shown in FIG. 5 and FIG. 6, the working faces of the first casing 1 and the second casing 2 that are closed are respectively a first working surface 7 and a second working surface 8, and the first working surface is 7 a plurality of air outlet holes 9 are provided at a position away from the air inlet hole 3, and the air outlet holes 9 are provided in plurality, and the array is disposed on the first working surface 7, so that the hair can receive the maximum wind power, in the second The working face 8 is provided with a plurality of air holes 10 which are distributed over the entire second working surface 8 for better contact with the hair. The wind entering from the air inlet hole is heated by the heating assembly and then discharged by the air outlet hole, and the first housing and the second housing are closed, so that the wind is along the first working surface 7 and the second working surface 8 Flowing between the contact gaps, or entering the second casing through the air holes, a sealed cavity in the second casing, and providing a gas hole penetrating into the sealing cavity on the second working surface, the air holes and the air outlet holes are formed a convective air passage, and a use surface 11 is disposed along the air outlet hole and the air inlet hole, and is configured to place the hair to be placed, and is closed by the first working surface and the second working surface, and is discharged when the air outlet hole is discharged. The wind acts directly on the hair held between the use surface and the second work surface to dry the hair.

[0020] While the first housing and the second housing are in a closed state, they will clamp the hair, so that when the cymbal is used, the hair can be straightened or the wet hair can be squeezed out.

[0021] As shown in FIG. 4, the circumferential directions of the first working surface and the second working surface are configured such that the first housing and the second housing are closed, and a seal is formed between the first working surface and the second working surface. a closed surface of the cavity, the first housing and the second housing are closed, and the upper and lower closing surfaces are in contact, so that a sealed cavity is formed between the first working surface and the second working surface, and the hot air can be in the cavity The inner circulation flows, and heat is resisted by the closed surface, thereby reducing heat leakage.
