Description

A hair dryer with improved air flow TECHNICAL FIELD

[0001] The present invention relates to a hair dryer with improved air flow. BACKGROUND

[0002] In the field of personal care appliances, especially in the field of hair styling tools, the optimization of performance and the innovation of technology have always been the focus of attention in this field as a daily life indispensable device. The traditional hair dryer is usually designed with a single air duct structure, driven by a motor to generate air flow, through the air inlet to suck in air, heated by the internal heating element, and then high-speed sprayed from the air outlet to achieve the effect of quickly drying the hair. However, such design often has uneven wind distribution, local overheating caused by heat concentration, high noise and high energy consumption, which affects the user's experience and hair blowing effect.

[0003] With the increasing demand of consumers for the performance of hair dryers, how to ensure high-speed drying while achieving more gentle and uniform wind distribution, reducing heat damage, and reducing operating noise has become the key direction of industry technological innovation. In order to cope with these challenges, some innovative attempts have appeared in the market, such as using more efficient motor technology to improve wind speed and reduce energy consumption, and designing multiple air duct systems to improve air flow uniformity and control heat distribution, which can be referred to the patent with patent number CN201811072185.1 and the name of ion hair dryer. However, these traditional hair dryers still use the same motor to drive the air inlet, and separate multiple channels after the air inlet, which can to some extent disperse the air volume, making the air volume more uniform, but cannot effectively increase the overall air volume of the hair dryer, and is also prone to local high temperature phenomenon.

[0004] Under this background, a new type of high-speed hair dryer emerges as the times require, which not only integrates advanced driving devices to generate strong and stable air flow, but also innovatively designs an auxiliary air duct structure. This design sets up an auxiliary air duct around the main air duct in the hair dryer body, and uses the high-speed air flow generated by the main air duct to drive the air flow in the auxiliary air duct. The ingenuity of this design is that it can effectively increase the overall air volume of the hair dryer without increasing additional energy consumption, making the wind distribution more uniform, reducing the local high temperature phenomenon caused by single air duct, and at the same time, due to the interaction between the air flow 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 blowing experience.

[0005] The present invention is precisely based on the above-mentioned deficiencies.

[0027] The embodiment provides an airflow improving hair dryer, as shown in FIG. 1 and FIG. 2, the airflow improving hair dryer is a whole product, namely a hair dryer body A, the hair dryer body A is composed of an inner cylinder 1, an outer cylinder 2, a connecting seat 4, a handle 5 and the like, the hair dryer body A is provided with a main air guide channel 10, a rear side of the hair dryer body A is provided with a main air inlet 101 which is in communication with the main air guide channel 10, a front side of the hair dryer body A is provided with a main air outlet 102 which is in communication with the main air guide channel 10, the hair dryer body A is provided with a driving device 3 which can generate airflow from the main air inlet 101 to the main air outlet 102, the driving device 3 is a fan motor of a general hair dryer, the driving device 3 can be arranged in the inner cylinder 1 or other positions, as long as it can drive the airflow in the main air guide channel 10. The hair dryer body A is further provided with a secondary air guide channel 20 which surrounds the outside of the main air guide channel 10 and penetrates through the front and back, and the secondary air guide channel 20 surrounds the outside of the main air guide channel 10, so that the front and back ends of the secondary air guide channel 20 are necessarily close to the main air inlet 101 or the main air outlet 102, and then, when the one-way 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 secondary air guide channel 20 according to Bernoulli's Principle.

[0028] As preferred, as shown in FIG. 1 and FIG. 2, the hair dryer body A is provided with the inner cylinder 1, an inner cavity of the inner cylinder 1 constitutes the main air guide channel 10, the outer cylinder 2 is connected and arranged around the outside of the inner cylinder 1, and a gap between the outer cylinder 2 and the inner cylinder 1 constitutes the secondary air guide channel 20, of course, the hair dryer body A can not be provided with the outer cylinder 2.

[0029] As preferred, as shown in FIG. 1 and FIG. 2, the rear side of the outer cylinder 2 is provided with a secondary air inlet 201 which is close to the main air inlet 101, and the front side of the outer cylinder 2 is provided with a secondary air outlet 202 which is close to the main air outlet 102. The secondary air outlet 202 is located at the front side of the main air outlet 102, and the secondary air inlet 201 is located at the front side of the main air inlet 101, as shown in FIG. 2, the front end of the outer cylinder 2 protrudes forward relative to the front end of the inner cylinder 1, the protruding interval is H2, that is, the interval between the secondary air outlet 202 and the main air outlet 102 is H2, so that the secondary air outlet 202 is located at the front side 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, the protruding interval is H1, that is, the interval between the secondary air inlet 201 and the main air inlet 101 is H1, so that the secondary air inlet 201 is located at the front side of the main air inlet 101.

[0030] As shown in Figure 2, in use, by the action of the driving device 3, the air flow is driven from the main inlet 101 into the main air guide channel 10 and then discharged from the main outlet 102, forming a first air flow P1. According to the Coanda effect, the air flow speed at the secondary outlet 202 is greater than that at the secondary inlet 201, and according to Bernoulli's principle, a second air flow P2 is formed in the secondary air guide channel 20 from the secondary inlet 201 to the secondary outlet 202, thereby widening the area of the air outlet and increasing the air volume.
