Description

Technical Field

[0001] This utility model relates to the field of air nozzle technology, and in particular to a diffuser nozzle and a high-speed air duct with air distribution function. Background Technology

[0002] A diffuser nozzle is an accessory installed on the air outlet of a hairdryer. Its function is to spread the airflow from the hairdryer, making the drying area larger and the airflow softer, thereby achieving the purpose of making the hair fluffy and styled. Most diffuser nozzles on the market do not change the direction of the airflow from the outlet, and their structure is complex and costly. In actual use, the airflow is mostly concentrated in the central area of ​​the diffuser nozzle, which does not achieve the purpose of fluffing and styling, resulting in a poor user experience. Utility Model Content

[0003] To address the aforementioned issues, this invention provides a diffuser nozzle and high-speed air duct with air distribution function. The first and second air guide rings evenly guide the incoming air from the nozzle's rear shell into the air chamber, from where it is then blown out through the first and second air outlets. In this application, when the airflow passes through the first and second air guide rings, it is reflected and dispersed to the surrounding area, preventing air from concentrating in the central region. This better achieves the purpose of drying and styling hair, improving the user experience. Furthermore, this application has a simple structure and low cost.

[0004] To achieve the above objectives, the present invention provides a diffuser nozzle with air distribution function, comprising a front nozzle shell, a rear nozzle shell installed on the front nozzle shell, and fastening screws. The rear nozzle shell is installed on the front nozzle shell by the fastening screws. The rear nozzle shell has a first air guide ring and a second air guide ring. The rear nozzle shell is provided with an air inlet and an air chamber. The air inlet communicates with the air chamber. The first air guide ring and the second air guide ring are both located at the connection between the air inlet and the air chamber, with the first air guide ring located inside the second air guide ring. The front nozzle shell is provided with a plurality of first air outlets and second air outlets, both of which are located in the air chamber.

[0005] As a preferred embodiment, the nozzle rear housing has a mounting bracket integrally formed on the nozzle rear housing, and both the first air guide ring and the second air guide ring are integrally formed on the mounting bracket.

[0006] As a preferred embodiment, both the first and second air guide rings have trapezoidal cross-sections.

[0007] As a preferred embodiment, the diameter of the first air outlet is smaller than the diameter of the second air outlet.

[0008] As a preferred embodiment, the nozzle front housing has an integrally formed mounting post with an internal threaded hole and an external threaded hole. Both the internal and external threaded holes are matched with the fastening screw, and one end of the fastening screw passes through the external threaded hole and is installed in the internal threaded hole.

[0009] As a preferred embodiment, the front shell of the nozzle has multiple spaced-apart snap-fit ​​portions, each snap-fit ​​portion having a snap-fit ​​groove, and the rear shell of the nozzle has multiple spaced-apart snap-fit ​​posts, the snap-fit ​​posts being matched with the snap-fit ​​grooves.

[0010] As a preferred embodiment, the nozzle front shell has an integrally formed air outlet column, the air outlet column has an air outlet channel, and the air outlet channel is connected to the second air outlet.

[0011] A high-speed air duct includes the aforementioned diffuser nozzle with air distribution function.

[0012] The beneficial effects of this utility model are as follows: the first and second air guide rings can evenly guide the air coming in from the back shell of the nozzle into the air chamber, and then send it out through the air chamber into the first and second air outlets. In this application, when the airflow passes through the first and second air guide rings, it will be reflected by the first and second air guide rings and then dispersed to the surrounding area, preventing the air from concentrating in the central area of ​​the air chamber. This allows the airflow to be evenly blown out from multiple first and second air outlets, which can better achieve the purpose of drying and styling hair and improve the user experience. At the same time, this application has a simple structure and low cost. Attached Figure Description

[0023] like Figures 1 to 6As shown, this utility model provides a diffuser nozzle with air distribution function, including a front nozzle shell 1, a rear nozzle shell 2 installed on the front nozzle shell 1, and fastening screws 3. The rear nozzle shell 2 is installed on the front nozzle shell 1 by the fastening screws 3. The rear nozzle shell 2 has a first air guide ring 21 and a second air guide ring 22. The rear nozzle shell 2 is provided with an air inlet 23 and an air chamber 24. The air inlet 23 communicates with the air chamber 24. The first air guide ring 21 and the second air guide ring 22 are both located at the connection between the air inlet 23 and the air chamber 24. The first air guide ring 21 is located inside the second air guide ring 22. The front nozzle shell 1 is provided with a plurality of first air outlets 11 and second air outlets 12. The first air outlets 11 and the second air outlets 12 are both located in the air chamber 24. By using the first air guide ring 21 and the second air guide ring 22, the air coming in from the nozzle back cover 2 can be evenly guided into the air chamber 24, and then blown out from the air chamber 24 into the first air outlet 11 and the second air outlet 12. In this application, when the airflow passes through the first air guide ring 21 and the second air guide ring 22, it will be reflected by the first air guide ring 21 and the second air guide ring 22 and then dispersed to the surrounding area, preventing the air from concentrating in the central area of ​​the air chamber 24. This allows the airflow to be evenly blown out from multiple first air outlets 11 and second air outlets 12, which can better achieve the purpose of drying and styling hair, improve the user experience, and at the same time, this application has a simple structure and low cost.

[0024] The nozzle rear shell 2 has a mounting bracket 25, which is integrally formed on the nozzle rear shell 2. The first air guide ring 21 and the second air guide ring 22 are both integrally formed on the mounting bracket 25.

[0025] Both the first air guide ring 21 and the second air guide ring 22 have trapezoidal cross sections.

[0026] The diameter of the first air outlet 11 is smaller than the diameter of the second air outlet 12.

[0027] The nozzle front shell 1 has an integrally formed mounting post 13, the mounting post 13 is provided with an internal threaded hole 14, and the mounting bracket 25 is provided with an external threaded hole 26. Both the internal threaded hole 14 and the external threaded hole 26 are matched with the fastening screw 3. One end of the fastening screw 3 passes through the external threaded hole 26 and is installed in the internal threaded hole 14.

[0028] The front housing 1 of the nozzle has multiple spaced-apart snap-fit ​​portions 15, each snap-fit ​​portion 15 having a snap-fit ​​groove 16. The rear housing 2 of the nozzle has multiple spaced-apart snap-fit ​​posts, which are matched with the snap-fit ​​grooves 16. The snap-fit ​​installation structure is easy to install and disassemble, and facilitates maintenance and cleaning.

[0029] The nozzle front shell 1 has an integrally formed air outlet column 17, which has an air outlet channel 18 that communicates with the second air outlet 12. The air outlet column 17 can be used to contact the user's hair and to emit airflow, increasing the area of ​​airflow diffusion.

[0030] This utility model also provides a high-speed air duct, including the aforementioned diffuser nozzle with air distribution function. When the device is working, the high-speed airflow blown out by the high-speed air duct enters the air chamber 24 through the air inlet 23. During this process, as the airflow passes through the first guide ring 21 and the second guide ring 22, it is reflected by the first and second guide rings 21 and dispersed to the surrounding area, preventing the air from concentrating in the central area of ​​the air chamber 24. This allows the airflow to be evenly blown out from multiple first air outlets 11 and second air outlets 12, better achieving the purpose of drying and styling hair, improving the user experience. Furthermore, this application has a simple structure and low cost.
