In order to make the objectives, technical means and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The specific examples described herein are intended to aid in a further understanding of the invention and are not intended to limit its appearance in any way.

A hair dryer provided in an embodiment of the present invention is provided with a first outlet and a second outlet in a body case, and extension lines of the first outlet and the second outlet in the blowing direction form an included angle. After connecting the suction port of the body case to the third outlet of the dryer, the wind emitted from the third outlet can be divided into two wind directions by the first outlet and the second outlet, When blowing hair with a hair dryer, it can be applied to different positions on the head at the same time, increasing the drying area of the head and improving the drying efficiency.

(Example 1)
Referring to FIGS. 1 to 3, the hair dryer comprises a main body case 1 and a hot air generator 3. The main body case 1 is provided with an air inlet 11 and at least two air outlets 12, and at least two air outlets. The outlets 12 are positioned on the same side of the main body case 1, that is, at least two outlets 12 are directed toward the same side, and the at least two outlets 12 can simultaneously blow hot air onto the head. The warm air generator 3 is provided in the body case, and is characterized by comprising a fan 31, a heating wire 32, and a driving member 33 for driving the fan.

The hair dryer provided in an embodiment of the present invention is provided with at least two blowing outlets 12, so that the blowing area of the hair dryer can be increased and the drying efficiency can be improved.

In this embodiment, the extension lines of the at least two outlets 12 may be arranged to form an included angle or may be arranged in parallel.

(Example 2)
1 to 3, based on the first embodiment, the body case 1 is also a columnar structure, and at least two outlets 12 are located on the same longitudinal side of the body case 1, that is, at least two By arranging the two outlets 12 on a straight line, a plurality of the outlets 12 are arranged in the same direction to increase the blowing area in the same direction.

(Example 3)
Referring to FIGS. 1-3, according to Example 1 or Example 2, the at least two outlets 12 further comprise a first outlet 121 for drying the crown area and a first outlet 121 for drying the occipital area. , the extension lines of the blowing direction of the first blower 121 and the second blower 122 form an included angle, and referring to FIG. Depending on requirements, a third outlet 123, a fourth outlet (not shown), etc. may be provided. In this embodiment, the other outlets of the at least two outlets 12 may be arranged in line with the first outlet 121 and the second outlet 122, or may be spaced apart. good.

During use, the air blown from the hair dryer is divided into two and blown out from the first blower outlet 121 and the second blower outlet 122, respectively. The first outlet 121 and the second outlet 122 are provided so as to form an included angle, so that two parts of the head that are not on the same plane, such as the top and the back of the head, can be dried at the same time. Increase drying area to improve drying efficiency. Of course, the crown and the side of the head, or the two sides of the head can also be dried, specifically according to the actual need.

Referring to FIG. 12, the included angle of extension lines in the blowing direction of the first outlet 121 and the second outlet 122 is 20° to 120°. When the hair dryer is used within this angle range, when the hair dryer is fixed to the head, for example, fixed to a fixed table, and the included angle is 20°, the extension line of the blowing direction of the first outlet 121 is to the top of the head. The extension line of the second outlet 122 in the blowing direction forms an included angle A with respect to the extension line of the first outlet 121. At this time, the hair dryer dries the top of the head and the lower part of the back of the head. Suitable for users with long hair. When the included angle is 120°, the extension line of the first outlet 121 in the blowing direction can be deflected to the rear of the top of the head with a vertical line perpendicular to the top of the head as the reference line, and the extension line of the second outlet 122 in the blowing direction forms an included angle A2 with the extension line of the first outlet 121 as a reference, at which time the hair dryer can dry the back of the top of the head and the upper part of the back of the head.

In order to accommodate the drying of different head areas, the included angle formed by the extending lines of the second outlet 122 and the first outlet 121 in the outlet direction can be varied within the range of 20° to 120°. That is, with the extension line of the blowing direction of the first blower outlet 121 as a reference, the extension line of the blowing direction of the second blower outlet 122 is gradually deflected from the lower part of the back of the head toward the upper part, and then the first blower outlet 121 By forming an included angle with the extension line, the included angle between the first outlet 121 and the second outlet 122 can be set according to actual needs.

Continuing to refer to FIG. 12, the included angle of extension lines of the first outlet 121 and the second outlet 122 in the outlet direction is 30° to 90°. In use, the extension of the first outlet 121 in the direction of ejection is perpendicular to the top of the head, and the second outlet 122 forms an included angle based on the extension of the direction of ejection of the first outlet 121. However, when the included angle gradually increases from 30° to 90°, the first outlet 121 of the hair dryer can dry the center of the top of the head, and the second outlet 122 can dry the area from the top to the bottom of the back of the head. can be dried.

Continuing to refer to FIG. 12, the included angle of extension lines in the blowing direction of the first outlet 121 and the second outlet 122 is 45° to 60°. while using it. The direction extension of the first outlet 121 is perpendicular to the top of the head, and the direction extension of the second outlet 122 is based on the direction extension of the first outlet 121. , and the included angle formed by the extension of the blowing direction of the first outlet 121 and the second outlet 122 at this time is A1. The first outlet 121 dries the central area of the top of the head and the second outlet dries the central area of the back of the head. In addition, part of the wind from the first outlet 121 and part of the wind from the second outlet 122 join and blow downward on the head, so the wind from the second outlet 122 blows the hair forward. It is possible to effectively prevent the head from being blown away. User discomfort can be avoided.

It should be noted that in setting the included angle between the extension line of the first outlet 121 and the extension line of the second outlet 122, the extension line of the first outlet 121 is perpendicular to the top of the head. One of the setting methods is to use a straight vertical line as a reference. In addition, the extension line of the first outlet 121 is an extension line in the blowing direction of the second outlet 122 after being deflected to the front part of the top of the head or to the rear of the top of the head with reference to the extension line perpendicular to the direction of the top of the head. , the extended line of the second outlet 122 in the blowing direction only needs to form an included angle with the extended line of the first outlet 121 in the blowing direction as a reference.

In this embodiment, the first outlet 121 and the second outlet 122 are provided with connecting portions for connecting to external members. The connecting portion may be a threaded structure provided at the first blowout port 121 and the second blowout port 122, or may be an engaging portion fitted to the external member or a magnetic attraction portion that is attracted to the external member. good. The external member may be a dividing member that again divides the wind directions of the first outlet 121 and the second outlet 122, but is not limited thereto.
