Description

Technical Field

[0001] This utility model relates to the field of hair dryer technology, and more particularly to a nozzle and hair dryer with increased airflow. Background Technology

[0002] Hair dryers are devices used in hair salons or by hairdressers to dry hair and are also used at home. Known hair dryers usually have a front nozzle or airflow concentrator. Most hair dryer nozzles on the market are designed to be flat. This is because, in order to achieve a fast drying effect, traditional hair dryer nozzles can only rely on making the nozzle flat to reduce the air outlet area and squeeze out airflow to increase airflow and temperature to dry the hair when the airflow is insufficient. In fact, drying hair with a hair dryer relies on two things: airflow and heat. If the airflow is not increased to dry the hair, and the temperature is too high, it will damage the hair cuticle and make the hair dull and dry. Utility Model Content

[0003] To solve the above problems, this utility model provides a nozzle and hair dryer with increased air volume. It utilizes the principle of aerodynamics. When the airflow is ejected, the negative pressure generated by the high speed and high pressure will drive the air flow in the middle. Finally, the ejected airflow is superimposed on the middle airflow, which will double the air volume, improve the drying efficiency, and allow the hair to be dried directly and naturally, instead of drying the hair with a regular hair dryer.

[0004] To achieve the above objectives, the present invention provides a nozzle with increased airflow, comprising a nozzle housing, a nozzle rear cover, and a nozzle inner liner installed on the nozzle housing. The nozzle housing is fastened to the nozzle rear cover, one end of the nozzle rear cover is located in the nozzle inner liner, the nozzle housing has a first air inlet, the nozzle inner liner has a second air inlet, the nozzle rear cover has an incremental air inlet hole, and guide vanes are provided on both sides of the incremental air inlet hole. Multiple guide vanes are provided and spaced apart. The first air inlet and the second air inlet are connected, and the guide vanes are correspondingly arranged with the second air inlet.

[0005] As a preferred embodiment, the nozzle housing is provided with a first receiving groove and a first air outlet, both the first air inlet and the first air outlet are connected to the first receiving groove, and the nozzle inner liner is installed in the first receiving groove.

[0006] As a preferred embodiment, the inner liner of the nozzle is provided with a second receiving groove and a second air outlet. Both the second air inlet and the second air outlet are connected to the second receiving groove. One end of the nozzle rear cover is installed in the second receiving groove. The second air outlet is connected to the first air outlet. The air guide plate is located in the second receiving groove. The incremental air inlet is connected to the second air outlet.

[0007] As a preferred embodiment, the nozzle rear cover has a retaining post, and the nozzle housing has a retaining groove that matches the retaining post. There are multiple retaining posts and retaining grooves, and they are matched one by one.

[0008] As a preferred embodiment, the nozzle housing has a heat insulation layer located in the first accommodating cavity, and the heat layer is located on the outer side of the inner wall of the nozzle liner.

[0009] As a preferred embodiment, the nozzle housing is provided with a connecting groove, which communicates with the first air inlet.

[0010] As a preferred embodiment, there are multiple connecting slots spaced apart, and the connecting slots are arranged in an L-shape.

[0011] A hair dryer, including the aforementioned nozzle with increased airflow.

[0012] The beneficial effects of this utility model are as follows: the air guide plate can reflect the air blown out by the main unit and blow it out of the nozzle. When it is sprayed out of the nozzle, the negative pressure generated by the high speed and high pressure will drive the air flow of the central incremental air inlet. Finally, the airflow that is sprayed out is superimposed with the airflow in the middle, which will double the air volume, improve the drying efficiency, and allow the hair to be dried directly and naturally, instead of drying the hair with a regular hair dryer.

[0021] like Figures 1 to 4 As shown, this utility model provides a nozzle with increased airflow, including a nozzle housing 1, a nozzle rear cover 3, and a nozzle inner liner 2 installed on the nozzle housing 1. The nozzle housing 1 is fastened to the nozzle rear cover 3, and one end of the nozzle rear cover 3 is located in the nozzle inner liner 2. The nozzle housing 1 has a first air inlet 11, and the nozzle inner liner 2 has a second air inlet 21. The nozzle rear cover 3 has an increasing air inlet hole 5, and air guide vanes 4 are provided on both sides of the increasing air inlet hole 5. Multiple air inlets are arranged at intervals. The first air inlet 11 and the second air inlet 21 are connected, and the air guide 4 is arranged corresponding to the second air inlet 21. The air guide 4 can reflect the air blown out by the main unit and blow it out of the nozzle. When it is sprayed out of the nozzle, the negative pressure generated by the high speed and high pressure will drive the air flow of the central incremental air inlet 5. Finally, the airflow that is sprayed out is superimposed with the airflow in the middle, which will double the air volume, improve the drying efficiency, and allow the hair to be dried directly and naturally, instead of drying the hair with a regular hair dryer.

[0022] The nozzle housing 1 is provided with a first receiving groove 12 and a first air outlet 13. The first air inlet 11 and the first air outlet 13 are both connected to the first receiving groove 12. The nozzle inner liner 2 is installed in the first receiving groove 12.

[0023] The inner liner 2 of the nozzle is provided with a second receiving groove 22 and a second air outlet 23. The second air inlet 21 and the second air outlet 23 are both connected to the second receiving groove 22. One end of the nozzle rear cover 3 is installed in the second receiving groove 22. The second air outlet 23 is connected to the first air outlet 13. The air guide 4 is located in the second receiving groove 22. The incremental air inlet 5 is connected to the second air outlet 23.

[0024] The nozzle back cover 3 has a retaining post 31, and the nozzle housing 1 has a retaining groove that matches the retaining post 31. There are multiple retaining posts 31 and retaining grooves, and they are matched one by one. The snap-on assembly structure is easy to disassemble and assemble, and facilitates maintenance and replacement of new parts.

[0025] The nozzle housing 1 has a heat insulation layer 14, which is located in the first accommodating space. The heat layer is located on the outer side of the outer wall of the nozzle inner liner 2. The heat insulation layer 14 is provided for heat insulation protection to prevent users from being burned when touching the nozzle.

[0026] The nozzle housing 1 is provided with a connecting groove 15, which is connected to the first air inlet 11; there are multiple connecting grooves 15 and they are spaced apart, and the connecting grooves 15 are L-shaped. The connecting grooves 15 are provided so that the present invention can be detachably installed on the hair dryer.

[0027] This utility model also provides a hair dryer, including a body and the aforementioned nozzle with increased airflow, the nozzle being adjustablely mounted on the body. When the device is working, the high-speed airflow blown out by the body enters the nozzle through the first air inlet 11, and after being reflected by the air guide 4, it is blown out of the nozzle. When ejected from the nozzle, the high speed and high pressure generate negative pressure, which drives the airflow of the central incremental air inlet 5. The final ejected airflow is superimposed on the central airflow, achieving a doubling of airflow, improving drying efficiency, and allowing hair to air dry naturally instead of being dried by a regular hair dryer.
