Detailed Description
The technical scheme of the invention is further described below by the specific embodiments with reference to the accompanying drawings.
The embodiment discloses an electric hair dryer structure. As shown in fig. 1, the electric hair dryer structure comprises a wind barrel 1, a wind shield 2 and a handle 4, wherein one end of the wind barrel 1 in a hollow straight barrel shape forms a first air outlet 11 (see fig. 2), the other end forms a second air outlet 12, and an air inlet 13 is formed on the side wall. The air inlet 13 is communicated with the first air outlet 11 to form a first air channel, and is communicated with the second air outlet 12 to form a second air channel. The wind shield 2 is arranged in the wind tunnel 1, the wind shield 2 can change the space position or the attitude by rotating and the like, and can also change the state by opening and closing different outlets, thereby determining whether the air flow is blown out from the first air outlet 11 or the second air outlet 12. Specifically, the wind shield 2 can selectively block one of the first air duct and the second air duct, and the other air duct is opened, thereby changing the air outlet direction of the electric blower.
As shown in fig. 2 and 3, the heating wire 6 is arranged in the air duct 1, and the heating wire 6 is positioned in the air duct between the first air outlet 11 and the air inlet 13. Specifically, the heating wire 6 is located between the first air outlet 11 and the impeller 3, and has a higher heating effect on the air outlet and a larger heating area. As shown in fig. 3a, when the second air outlet 12 is shielded by the windshield 2 and the first air outlet 11 is opened, the air flow is heated when passing through the heating wire 6, so that a hot air flow is formed at the first air outlet 11; as shown in fig. 3b, when the wind shield 2 shields the first air outlet 11 and opens the second air outlet 12, the air flow is directly blown out from the second air outlet 12, and the heating wire 6 does not change the temperature of the air outlet. That is, the rapid transition from hot air to cold air can be realized by only changing the orientation of the windshield 2.
As shown in fig. 2 and 4, the windshield 2 has a hollow spherical structure, and the housing is closed except for the inlet 21 and the outlet 22. Wherein the inlet 21 is always aligned with the air inlet 13, and the outlet 22 is aligned with the air outlet (the first air outlet 11 or the second air outlet 12) on the air duct 1. The impeller 3 is arranged in the windshield 2, and in the process of rotating the windshield 2, only the position where the outlet 22 faces is provided with blowing, and the other directions are not provided, so that the blowing direction can be accurately controlled. The electric blower will only generate air when the outlet 22 is aligned with the first air outlet 11 or with the second air outlet 12.
The specific rotation mode of the windshield 2 is not limited, and the direction may be changed quickly and smoothly. In this embodiment, the electric hair dryer structure includes a handle 4, a motor 5 is disposed in the handle 4, an output end of the motor 5 is connected to a rotating shaft of the impeller 3, and the windshield 2 is connected to the handle 4 and can rotate along with the rotation of the handle 4. When the hot air flow is required to be changed into the cold air flow, the handle 4 is only required to be rotated, and the handle 4 can drive the windshield 2, the impeller 3 and the motor 5 to rotate together around the axis of the handle 4.
In order to avoid the winding of the circuits inside and outside the electric hair dryer, the rotation angle A of the handle 4 is controlled within 180 degrees. In order to reduce the processing difficulty and increase the airflow speed and the airflow rate, the air inlet 13 and the handle 4 are arranged oppositely, i.e. the air inlet 13 and the handle 4 are symmetrically arranged about the axis of the air duct 1.
In order to prevent the wind shield 2 from lateral displacement when rotating, the inner side of the wind barrel 1 is inwards protruded to form a positioning convex edge 14, a step structure is formed at the edge of an inlet 21 of the wind shield 2, and the positioning convex edge 14 is clamped on the step structure, so that the wind shield 2 is limited from moving towards the direction perpendicular to the axis of the handle 4.
In order to enable the air inlet to be totally controlled in flow direction by the windshield 2, the air inlet 13 is positioned within the range of the positioning flange 14. I.e. the inlet opening 13 is perfectly aligned with the inlet opening 21 of the windscreen 2.
Note that the above is only a preferred embodiment of the present invention and the technical principle applied. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, while the invention has been described in connection with the above embodiments, the invention is not limited to the embodiments, but may be embodied in many other equivalent forms without departing from the spirit or scope of the invention, which is set forth in the following claims.
