Description

TECHNICAL FIELD

The present disclosure relates to the technical field of electric hair driers, in particular to a double-duct hot air guide structure and a hair drier thereof.

BACKGROUND

The electric hair drier is a beauty appliance used for hair drying and shaping, but also can be used for local drying, heating and physical therapy in laboratories, physiotherapy rooms, industrial production and art design. The electric hair drier is also known as a hair dryer and a hair drier. The existing hair drier generally use a high-speed brushless motor, and can provide greater wind power and higher hair drying speed. With intelligent constant temperature technology, some hair driers can automatically adjust the temperature to prevent overheated air from damaging hair, so that the hair is preferably protected from injury. In addition to better improvement on the blowing speed and temperature of the hair drier, a negative ion function is added to the hair drier for more manufacturers. Negative-ion hair drier can release negative ions and reduce static electricity, so that the hair is smooth, and the function is very helpful for improving hair texture.

However, although the existing hair drier can automatically adjust the temperature, the temperature uniformity of air blown out by the hair drier is limited by the structures of the heating module and the air outlet. In order to achieve a better air uniformity effect, ceramic heating technology is also introduced into some hair driers, the ceramic heating technology is used in the ceramic hair drier to provide a more uniform air temperature and reduce damage to the scalp. However, when hot air is blown out from the air outlet, the temperature from the edge of the air outlet to the center of the air outlet is gradually increased, resulting in excessive local temperature. Especially, the high-speed hair drier can generate a large high-temperature impact on the scalp locally, so that the hair drier cannot blow air to a certain part of the scalp for a long time when the hair drier is used. In order to solve this problem, a wind-shielding structure is arranged at the central position of the air outlet of the hair drier in the prior art, but the wind-shielding structure can affect the air outlet efficiency. Therefore, it is necessary to propose a novel technical scheme to solve the above-mentioned problem.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The following clearly and completely describes the technical scheme in the embodiments of the present disclosure with reference to the attached figures in the embodiments of the present disclosure. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present disclosure. Based on the embodiment in the present disclosure, all other embodiments acquired by the ordinary technical staff in the art under the premise of without contributing creative labor belong to the scope protected by the present disclosure.

Referring to FIG. 1 to FIG. 8, in the embodiment of the present disclosure, a double-duct hot air guide structure includes a shell 10, a heating module 20 and blowing module 30. The shell 10 is provided with an outer sleeve-shaped body 11 and an inner sleeve-shaped body 12 mounted inside the outer sleeve-shaped body 11. A front end of the outer sleeve-shaped body 11 is matched with a front end of the inner sleeve-shaped body 12 through butting so that an inner air outlet 13 inside the inner sleeve-shaped body 12 correspondingly and an outer air outlet 14 between the outer sleeve-shaped body 11 and the inner sleeve-shaped body 12 correspondingly are formed in a front end of the shell 10. The heating module 20 is arranged between the outer sleeve-shaped body 11 and the inner sleeve-shaped body 12.

An air inlet 15 is formed in a rear end of the outer sleeve-shaped body 11. An accommodating cabin 16 taking the outer sleeve-shaped body 11 as a wall surface is formed between the rear end of the outer sleeve-shaped body 11 and a rear end of the inner sleeve-shaped body 12. The blowing module 30 is mounted inside the accommodating cabin 16. A first fluid 17 entering along the air inlet 15 and then flowing out along the inner air outlet 13 is formed inside the shell 10 through the blowing module 30. A second fluid 18 entering along the air inlet 15 and flowing out along the outer air outlet 14 after passing through the heating module 20 is also formed inside the shell 10 through the blowing module 30.

In the above-mentioned technical scheme, the inner sleeve-shaped body 12 and the outer sleeve-shaped body 11 are matched with each other inside and outside, so that the first fluid 17 which can flow out along the inner air outlet 13 and the second fluid 18 which can flow out along the outer air outlet 14 are formed. Both the first fluid 17 and the second fluid 18 are generated through the blowing module 30, wherein the first fluid 17 cannot pass through the heating module 20. Therefore, a low-temperature air-out effect can be generated. The second fluid 18 flows through the heating module 20, and a high-temperature air-out effect is generated after the heating of the heating module 20. Low-temperature outlet air is arranged inside high-temperature outlet air, and the structure is applied to the hair drier. When the hair drier runs, high-temperature air blown out from the outer air outlet 14 is fused with low-temperature air blown out from the inner air outlet 13, so that blowing temperature in the middle can be cooled, air blown out from the air outlet of the hair drier is uniform in temperature, and excessive temperature accumulation in the middle cannot be generated to result in a scald feeling for user scalp when in use. Moreover, with the structural arrangement of the outer air outlet and the inner air outlet, fluids, entering the air outlet to blow out along the air inlet 15, generated by the blowing module 30 can be separated, so that an appointed fluid is heated. In this way, outlet air in the middle of the air outlet of the hair drier is blocked without setting a blocking structure, so that higher air outlet efficiency and more uniform air outlet temperature can be realized in the application of high-temperature hair driers, and the user can heat and blow air for a long time to one part without a scald feeling when using the hair drier.

Referring to FIG. 2 to FIG. 4, in the embodiment, in order to achieve better blowing effect of the hair drier, ensure that more fluids generated by the blowing module 30 flow through the heating module 20 and achieve a high-speed blowing effect for this part of fluids, the inner sleeve-shaped body 12 is provided with a first sleeve part 121 at the rear end and a cambered first flared part 122 expanding and extending outwards along a front end of the first sleeve part 121, and the inner air outlet 13 is formed in one end, located at the first flared part 122, of the inner sleeve-shaped body 12. Through the arrangement of the first sleeve part 121 and the first flared part 122, the flow rate of the first fluid 17 can be reduced, and a fluid accumulation effect can be achieved for the outer air outlet 14 for the second fluid 18 to flow out to ensure that the flow rate of the second fluid 18 is considerably higher than that of the first fluid 17. When the first fluid 17 flows out along the inner air outlet 13, the first fluid 17 plays a cooling role in the middle part of the second fluid 18, but cannot directly acts on user hair. Otherwise, a high-temperature drying effect cannot be caused for the middle part of the fluid. Therefore, the fluid finally acting on user scalp includes the outer periphery of the second fluid 18 and the inner periphery of the second fluid 18 after passing through the first fluid for cooling. Thus, through the design of the structure, the air-out effect can be controlled more effectively, so that a required uniform temperature effect can be achieved more easily. Moreover, a plurality of arc-shaped strips 123 uniformly distributed are arranged around an inner wall of the first flared part 122. A spirally outward effect can be generated for the first fluid 17, so that the first fluid 17 can act on the second fluid 18 preferably.
