Description
Technical Field
[0001] The utility model relates to the technical field of hair dryers, in particular to a double-air-channel heat-conducting wind structure and a hair dryer thereof. Background Art
[0002] A hair dryer is a cosmetic appliance used for drying and shaping hair, but it can also be used for local drying, heating and physical therapy in laboratories, physiotherapy rooms, industrial production, art, etc. It is also called a hair dryer or hair dryer. Existing hair dryers generally use high-speed brushless motors, which can provide greater wind power and faster hair drying speed. Some hair dryers also add intelligent constant temperature technology, which can automatically adjust the temperature to prevent overheated air from damaging the hair, thereby better protecting the hair from damage; in addition to improving the blowing speed and temperature of the hair dryer, many manufacturers will add negative ion function to the hair dryer. Negative ion hair dryers can release negative ions, reduce static electricity, and make hair smoother. This function is very helpful for improving hair texture.
[0003] However, although the existing hair dryers can automatically adjust the temperature, the temperature uniformity of the air blown out by the hair dryers is limited by the structure of the heating module and the air outlet. In order to achieve a better wind uniformity effect, some hair dryers have also introduced ceramic heating technology. Ceramic hair dryers use ceramic heating technology to provide a more uniform wind temperature and reduce damage to the scalp; but 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 will gradually increase, resulting in excessive local temperature, especially for high-speed hair dryers, which will produce a large high-temperature impact on the local scalp, resulting in the inability to blow on a certain part of the scalp for a long time when using the hair dryer. To solve this problem, the existing technology also proposes to set a wind shield structure at the center of the air outlet of the hair dryer, but the wind shield structure will affect the air outlet efficiency. In this regard, it is necessary to propose a new technical solution to solve the above problem. Utility Model Content

DETAILED DESCRIPTION
[0031] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0032] See also Figure 1-8 In the embodiment of the utility model, a dual-air-duct heat-conducting wind structure includes a shell 10, a heating module 20 and a blowing module 30. The shell 10 has an outer sleeve 11 and an inner sleeve 12 installed inside the outer sleeve 11. The front end of the outer sleeve 11 and the front end of the inner sleeve 12 are butt-jointed, so that the front end of the shell 10 has an inner air outlet 13 corresponding to the inner sleeve 12 and an outgoing air outlet 14 corresponding to the outer sleeve 11 and the inner sleeve 12. The heating module 20 is arranged between the outer sleeve 11 and the inner sleeve 12.
[0033] The rear end of the outer sleeve 11 is the air inlet 15, and a containing chamber 16 with the outer sleeve 11 as the wall is formed between the rear end of the outer sleeve 11 and the rear end of the inner sleeve 12. The blowing module 30 is installed in the containing chamber 16. The shell 10 is formed with a first fluid 17 through the blowing module 30, which enters along the air inlet 15 and then flows out of the inner air outlet 13. The shell 10 is also formed with a second fluid 18 through the blowing module 30, which enters along the air inlet 15 and passes through the heating module 20 and then flows out along the outer air outlet 14.
[0034] In the above technical solution, the inner and outer sleeve-shaped body 12 and the outer sleeve-shaped body 11 are arranged to cooperate with each other, so as to form a first fluid 17 that can flow out along the inner air outlet 13 and a second fluid 18 that can flow out along the outer air outlet 14. The first fluid 17 and the second fluid 18 are both generated by the blowing module 30, wherein the first fluid 17 will not pass through the heating module 20, and thus can produce a low-temperature air outlet effect, and the second fluid 18 flows through the heating module 20, and after being heated by the heating module 20, it will produce a high-temperature air outlet effect. By setting the low-temperature air outlet within the high-temperature air outlet, the structure is applied to the hair dryer. When the hair dryer is in operation, the high-temperature air blown out of the outer air outlet 14 and the low-temperature air blown out of the inner air outlet 13 are The wind is integrated with each other, so that the blowing temperature of the middle part can be cooled down, and the temperature of the wind blown out along the air outlet of the hair dryer is uniform, and there will be no excessive heat accumulation in the middle part, which will cause a burning sensation to the user's scalp when using it; in addition, the structural setting of the outward wind and the inner wind can separate the fluid generated by the blowing module 30 that enters the air outlet along the air inlet 15, so as to achieve the heating of the designated fluid. This method does not need to set a blocking structure to block the air outlet in the middle of the hair dryer outlet, so that higher air outlet efficiency and more uniform air outlet temperature can be achieved in the application of high-speed hair dryers, so that users can heat and blow one part for a longer time when using the hair dryer without causing a burning sensation.

Therefore, the fluid that finally acts on the user's scalp is partly the outer part of the second fluid 18, and the other part is the inner part of the second fluid 18 after being cooled by the first fluid 17. Therefore, the design of this structure will be able to more effectively control the air outlet effect, thereby making it easier to achieve the required uniform temperature effect; in addition, a plurality of evenly distributed arc strips 123 are arranged around the inner wall of the first expansion portion 122; they can produce a spiral outward effect on the first fluid 17, so as to better act the first fluid 17 on the second fluid 18.
