Preferably, a wire is arranged in the gap to connect electrical elements at two ends of the fan.

Preferably, the electrical element in one end of the fan close to the air outlet comprises a heating wire; and the electric element at one end of the fan close to the air inlet comprises a power supply.

Preferably, a key driving circuit board is arranged in a gap between the fan and the shell with the second curvature; and an operating key is arranged at the position of the shell corresponding to the circuit board.

This patent adopts above-mentioned technical scheme, sets up the bigger molding of camber keeping away from air outlet one side for the staff more comfortably laminates this one side to the palm when gripping, so easily grips, utilizes the clearance between the bigger one side of camber and the motor to walk the line simultaneously, is convenient for set up the circuit.

Drawings

In order to more clearly illustrate the embodiments of the present specification or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments described in the embodiments of the present specification, and other drawings can be obtained by those skilled in the art according to the drawings.

FIG. 1 is a view showing an external structure of a hair dryer in this embodiment;

FIG. 2 is a bottom view of the blower of this embodiment;

figure 3 is a cross-sectional view of the structure of a hair dryer according to the embodiment of the present patent.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

For the purpose of facilitating understanding of the embodiments of the present application, the following description will be made in terms of specific embodiments with reference to the accompanying drawings, which are not intended to limit the embodiments of the present application.

This embodiment provides a handheld hair-dryer, including casing 1, the whole barrel-shaped that forms of casing, be provided with an air outlet 3 on the one end lateral wall of barrel-shaped casing, the other end lateral wall is provided with air intake 2, the centre of barrel-shaped casing is provided with fan 4, the entry end of fan with the air intake links to each other, the exit end of fan with the air outlet links to each other.

One side 5, close to the air outlet, of the cross section of the cylindrical shell has a first curvature, and one side 6, far away from the air outlet, of the cylindrical shell has a second curvature; the second curvature is greater than the first curvature. Although one side and the other side are limited in this patent, it can be seen from the drawings that one side and the other side in this application do not have a definite boundary, that is, they refer to relative concepts indicating relative positions close to and far from the outlet.

When the object is held by the hand, the joints connected with the palm at the tail ends of the fingers are folded and furled, the position generally has larger curvature relative to other parts of the hand, and when the hair drier is operated by a person, the air outlet of the hair drier deviates from the palm, so that the hair drier is safe and convenient to operate, and the orientation of the hair drier is easy to distinguish when the air outlet is arranged on the two sides of the shell with different curvatures, so that the hair drier can be held by the person conveniently, and the safety is ensured.

Furthermore, in the present embodiment, a gap 7 is formed between the blower and the housing having the second curvature; an electrical circuit is disposed in the gap. Because the inner space of the cylindrical hair drier is very limited, the wiring is a problem to be considered, in the specific embodiment, the extra wiring space can not be arranged by utilizing the gap between the position with larger curvature and the fan, and therefore an unexpected technical effect is achieved.

Preferably, the shell of the fan is circular, and at least part of the shell is attached to the shell with the first curvature; therefore, the motor can be fixed without extra space while wiring, and the stable position of the fan can be kept by utilizing the change of the curved surface of the shell.

In this embodiment, a lead is disposed in the gap to connect electrical components at two ends of the fan. The electric element in one end of the fan close to the air outlet comprises a heating wire 9; and the electric element at one end of the fan close to the air inlet comprises a power supply 8. Therefore, the problem of circuit communication of two sides when the fan is arranged in the middle is solved, and the fan can provide larger wind power for the air outlet.

Still further preferably, a key driving circuit board 10 is disposed in a gap between the blower and the housing having the second curvature; an operating key 11 is arranged at the position of the shell corresponding to the circuit board. The keys are arranged on the back side, so that the gap is utilized, but the fingers can be extended to operate the keys conveniently when the keys are held by the palm of a user, and the man-machine effect is improved.

The above-mentioned embodiments, objects, technical solutions and advantages of the present application are described in further detail, it should be understood that the above-mentioned embodiments are merely exemplary embodiments of the present application, and are not intended to limit the scope of the present application, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present application should be included in the scope of the present application.
