Description

Technical Field

[0001] The utility model particularly relates to a hair dryer with a double-channel structure. Background Art

[0002] In the field of personal care appliances, especially hairdressing tools, dual-channel hair dryers are an indispensable part of daily life, and their performance optimization and technological innovation have always been a focus of attention. Traditional hair dryers are typically designed with a single air duct structure, where a motor drives a fan to generate airflow, drawing air in through an air inlet, heating it with an internal heating element, and then ejecting it from the air outlet at high speed to achieve the effect of quickly drying hair. However, this type of design often suffers from problems such as uneven wind distribution, concentrated heat leading to localized overheating, high noise levels, and high energy consumption, which affect the user experience and hair drying results.

[0003] As consumers' requirements for hair dryer performance continue to increase, how to achieve a softer and more uniform wind distribution, reduce heat damage, and reduce operating noise while ensuring high-speed drying has become a key direction of technological innovation in the industry. In order to meet these challenges, some innovative attempts have emerged in the market, such as the use of more efficient motor technology to increase wind speed and reduce energy consumption, and the design of multiple air duct systems to improve the uniformity of airflow and control heat distribution. For example, the patent solution with patent number CN201811072185.1, named ion hair dryer, can be referred to. However, these traditional hair dryers still use the same motor to drive the air intake, and separate multiple channels after the air enters. This can disperse the air output to a certain extent, making the air output more uniform, but it cannot effectively increase the overall air output of the hair dryer, and it is also prone to local high temperature.

[0004] Against this backdrop, a new type of high-speed hair dryer has emerged. It not only integrates an advanced drive device to generate a strong and stable airflow, but also innovatively designs an auxiliary air duct structure. This design sets up an auxiliary air duct around the main air duct around the hair dryer body, and uses the high-speed airflow generated by the main air duct to drive the air flow in the auxiliary air duct. The cleverness of this design is that it can effectively increase the overall air output of the hair dryer without increasing additional energy consumption, making the wind force distribution more even and reducing the local high temperature phenomenon that may be caused by a single air duct. At the same time, due to the interaction between the airflow of the auxiliary air duct and the main air duct, it also helps to reduce the noise level during operation, bringing users a more comfortable hair-drying experience.

[0005] The present invention is based on the above-mentioned shortcomings and produces. Utility Model Content

[0006] The utility model aims to overcome the deficiencies of the prior art and provide a hair dryer with a dual-channel structure that improves energy efficiency and produces more uniform air flow.

Moreover, through the barrier effect of the auxiliary air guide channel and the outer cylinder, the outside and the inner cylinder can be separated, thereby reducing noise and weakening vibration.

[0026] The embodiment provides a double-channel structure hair dryer, as shown in Figure 1 And Figure 2 The whole product of the double-channel structure hair dryer is hair dryer body A, the hair dryer body A is composed of inner cylinder 1, outer cylinder 2, connecting seat 4, handle 5 and the like, the hair dryer body A is provided with main air guide channel 10, the rear side of the hair dryer body A is provided with main air inlet 101 communicated with the main air guide channel 10, the front side of the hair dryer body A is provided with main air outlet 102 communicated with the main air guide channel 10, the hair dryer body A is provided with driving device 3 capable of generating airflow from the main air inlet 101 to the main air outlet 102, the driving device 3 is the fan motor of general hair dryer, the driving device 3 can be arranged in the inner cylinder 1, or can be arranged in other positions, as long as the gas in the main air guide channel 10 can be driven to flow. The hair dryer body A is also provided with auxiliary air guide channel 20 surrounding the outer side of the main air guide channel 10 and penetrating front and back, and the auxiliary air guide channel 20 surrounds the outer side of the main air guide channel 10, so that the openings of the front and back ends of the auxiliary air guide channel 20 are necessarily close to the main air inlet 101 or the main air outlet 102, and then, when unidirectional airflow is generated in the main air guide channel 10, the airflow of the main air inlet 101 and the main air outlet 102 of the main air guide channel 10 can drive the airflow in the auxiliary air guide channel 20 according to Bernoulli's Principle.

[0027] As preferred, as shown in Figure 1 And Figure 2 The hair dryer body A is provided with inner cylinder 1, the inner cavity of the inner cylinder 1 constitutes the main air guide channel 10, the outer cylinder 2 surrounding the outer side of the inner cylinder 1 is connected, and the gap between the outer cylinder 2 and the inner cylinder 1 constitutes the auxiliary air guide channel 20, of course, the hair dryer body A can also not be provided

[0028] As preferred, as shown in Figure 1 And Figure 2As shown, the rear side of the outer cylinder 2 has a secondary air inlet 201 arranged near the main air inlet 101, and the front side of the outer cylinder 2 has a secondary air outlet 202 arranged near the main air outlet 102. The secondary air outlet 202 is located in front of the main air outlet 102, and the secondary air inlet 201 is located in front of the main air inlet 101. Figure 2 As shown, the front end of the outer cylinder 2 protrudes forward relative to the front end of the inner cylinder 1, and the protruding distance is H2, that is, the distance between the auxiliary air outlet 202 and the main air outlet 102 is H2, so that the auxiliary air outlet 202 is located in front of the main air outlet 102; the rear end of the inner cylinder 1 protrudes backward relative to the rear end of the outer cylinder 2, and the protruding distance is H1, that is, the distance between the auxiliary air inlet 201 and the main air inlet 101 is H1, so that the auxiliary air inlet 201 is located in front of the main air inlet 101.

[0029] like Figure 2 As shown, during use, through the action of the driving device 3, the air flow passively enters the main air flow channel 10 from the main air inlet 101 and is discharged from the main air outlet 102, forming a first air flow P1. Since the auxiliary air outlet 202 is located in front of the main air outlet 102 and the auxiliary air inlet 201 is located in front of the main air inlet 101, according to the Coanda effect, the air flow velocity at the auxiliary air outlet 202 is greater than the flow velocity at the auxiliary air inlet 201. Following the Bernoulli principle, a second air flow P2 is formed in the auxiliary air guide channel 20 from the auxiliary air inlet 201 to the auxiliary air outlet 202, thereby widening the air outlet area and increasing the air outlet volume. In addition, by mixing the cold and hot air flows of the first air flow P1 and the second air flow P2, it is possible to effectively prevent problems such as local temperature being too high and local humidity being too low at the air outlet of the hair dryer. Moreover, through the barrier effect of the auxiliary air guide channel 20 and the outer cylinder 2, the outside and the inner cylinder 1 can be separated, thereby reducing noise and weakening vibration. Through the above structure, the airflow of the auxiliary air guide channel 20 does not require a driving device at all, that is, no additional fan motor is required. This is different from the existing solution in which multiple channels supply air together or individually through a driving device. It not only reduces the structure and the product volume, but also has a compact structure and saves production costs.
