Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments; the technical features designed in different implementation modes of the present invention described below can be combined with each other as long as they do not conflict with each other; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be noted that all terms (including technical terms and scientific terms) used in the present invention have the same meanings as those generally understood by ordinary technicians in the field to which the present invention belongs, and should not be understood as limitations on the present invention; it should be further understood that the terms used in the present invention should be understood to have the same meanings as these terms in the context of this specification and in the relevant fields, and should not be understood in an idealized or overly formal sense, unless explicitly defined in this invention.

[0022] Although the numerical ranges and parameters listed for the broad scope of the present invention are approximate, the numerical values ​​listed in the specific examples are recorded as accurately as possible. However, any numerical value inherently has a certain error. The error is the inevitable result of the standard deviation obtained in its corresponding measurement method.

[0023] In addition, it should be understood that any numerical range described herein is intended to include all subranges subsumed therein. For example, a range of "1 to 10" is intended to include all subranges between (and including) the stated minimum value of 1 and the stated maximum value of 10, i.e., having a minimum value equal to or greater than 1 and a maximum value equal to or less than 10.

[0024] The present invention provides a hair dryer nozzle, such as Figures 1 to 3 As shown, it includes a first air guide plate 130 , a first shell 110 and a second shell 120 .

[0025] The length of the first shell 110 is smaller than that of the second shell 120; the second shell 120 includes an air guide section 121 and an air outlet section 122 that are interconnected, and the air guide sections 121 of the first shell 110 and the second shell 120 cooperate with each other to form an air guide channel structure having an air inlet and an air outlet; the air outlet is a flat opening structure.

[0026] The air outlet section 122 of the second housing 120 is inclined or curved relative to the air guide section 121. Specifically, the air outlet section 122 is inclined or curved so that its end gradually moves away from the first housing 110.

[0027] A portion of the first air guide 130 is disposed in the air outlet, and the remaining portion is disposed outside the air outlet in a direction extending toward the air outlet section 122, so as to guide the direction of the airflow out of the air outlet to a direction close to the extension direction of the air outlet section 122. That is, the first air guide 130 extends from the air outlet to the air outlet section 122 of the second housing 120.

[0028] During actual operation, the external wind enters the wind guide channel structure through the air inlet formed by the cooperation between the first shell 110 and the wind guide section 121 of the second shell 120, and forms an outlet airflow at the air outlet at the end of the wind guide channel structure. The outlet airflow contacts the first air guide plate 130 and the outlet section 122 of the second shell 120. Since the outlet section 122 of the second shell 120 is inclined or curved relative to the wind guide channel structure, and the first air guide plate 130 spans the wind guide channel structure to the outlet section 122, the outlet airflow produces a Coanda effect under the action of the outlet section 122 and the first air guide plate 130, and then flows along the surface of the first air guide plate 130 and the outlet section 122 to form an adsorption fluid, thereby adsorbing the user's hair during use. Due to the different positions of the airflow along the surface of the first air guide plate 130 and the airflow along the surface of the outlet section 122 contacting the hair, the hair is subjected to two adsorption forces, front and back, thereby producing a straightening effect on the hair without damaging the hair.

[0029] Preferably, Figure 3 As shown, the first air guide 130 separates the outlet airflow in the air outlet into a first airflow located between the first housing 110 and the first air guide 130 and a second airflow located between the first air guide 130 and the second housing 120. The first air guide 130 is arranged in the direction in which the air outlet section 122 extends, so that the direction of the second airflow is closer to the direction in which the air outlet section 122 extends than the direction of the outlet airflow. Specifically, after the first air guide 130 is arranged in the direction in which the air outlet section 122 extends, the direction of the second airflow is further offset, effectively enhancing the straightening effect.

[0030] Further, such as Figure 2 As shown, it also includes a fixing frame 150, which is arranged on both sides of the second shell 120. The first air guide 130 is fixed to the second shell 120 through the fixing frame 150, and the first air guide 130 separates the airflow of the air outlet into two layers, upper and lower. The setting of the fixing frame 150 prevents the first air guide 130 from being offset during use, thereby ensuring the adsorption and straightening effects. Specifically, the first air guide 130 can be fixed on the fixing frame 150 in the form of a slide groove, a limit block, a screw connection, etc., and those skilled in the art can set it according to needs without specific restrictions.

[0031] In one embodiment, if Figures 2-3 The first air guide 130 is provided with a spacing rib 160, which is provided on a side close to the air outlet. The provision of the spacing rib 160 can effectively prevent the first air guide 130 from being attached to the first housing 110 during use, thereby ensuring the normal use of the hair dryer nozzle 100. In addition, the spacing rib 160 can further divide the first airflow flowing on the surface of the first air guide 130 into several small airflows, making the overall distribution of the first airflow more uniform, thereby improving the straightening and adsorption effects.

[0032] Preferably, Figures 1 to 3 As shown, the hair dryer 100 further includes a second air guide 140, one end of which is arranged between the first air guide 130 and the air guide section 121, and the other end of the second air guide 140 extends out of the area covered by the first air guide 130, thereby the second air guide 140 separates the second airflow into a third airflow between the first air guide 130 and the second air guide 140 and a fourth airflow between the second air guide 140 and the second shell 120, and the second air guide 140 is arranged in the direction extending toward the air guide section 121, so that the direction of the third airflow is closer to the direction of the shell extension than the direction of the outlet airflow. Specifically, by setting the second air guide 140, the second airflow is further divided, and a three-layer adsorption fluid is formed as a whole. In addition, the setting of the second air guide 140 makes the contact surface between the hair and the hair dryer nozzle 100 as a whole smoother when the hair is adsorbed, and combined with the three-layer adsorption fluid, the straightening effect is further improved.

[0033] Further, such as Figure 2 As shown, two fixing frames 150 are also included, and the fixing frames 150 are respectively arranged on both sides of the second shell 120. The first air guide 130 is fixed to the second shell 120 through the fixing frames 150. The fixing frames 150 and the air outlet section 122 are combined to form an airflow slot structure, and the first air guide 130 is arranged in the airflow slot structure. Specifically, the airflow slot structure formed by the fixing frame 150 and the air outlet section 122 can effectively limit the divergence of the airflows on both sides, so that the first airflow and the second airflow are limited in the airflow slot structure, improve the air concentration, reduce wind attenuation, and thus ensure the straightening effect and drying efficiency.

[0034] Preferably, Figure 3 As shown, the curvature of the first air guide plate 130 is smaller than the curvature of the air outlet section 122 of the second shell 120, that is, the first air guide plate 130 is flatter than the air outlet section 122 of the second shell 120, and the setting can ensure the air volume of the second airflow, thereby ensuring the adsorption and straightening effect.

[0035] Further, such as Figure 3 As shown, the curvature of the second air guide plate 140 is less than or equal to the curvature of the air outlet section 122 of the second shell 120 .

[0036] In one embodiment, a magnetic suction component 170 is also included, and the magnetic suction component 170 is arranged at the air inlet. The magnetic suction component 170 enables the hair dryer nozzle 100 to be fixed to the outside through the direction of magnetic suction, which is convenient for consumers to use. Specifically, the magnetic suction component 170 can adopt a combination of a fixed bracket and an iron sheet. Those skilled in the art can select a suitable magnetic suction component 170 according to actual needs to ensure that the air inlet can flow smoothly and can be magnetically attracted to the outside, without specific restrictions.

[0037] like Figure 4 As shown, the present invention also provides a hair dryer 200 using any of the hair dryer nozzles 100 described above, wherein the hair dryer nozzle 100 is made of a heat-resistant material. Specifically, the heat-resistant material can ensure that the hair dryer nozzle 100 does not deform during the drying process, thereby ensuring the adsorption and straightening effect on the hair.

[0038] In addition, those skilled in the art should understand that, although there are many problems in the prior art, each embodiment or technical solution of the present invention can be improved in only one or several aspects, without having to solve all the technical problems listed in the prior art or background technology at the same time.
