Abstract

The utility model discloses a noise reduction air duct structure and a hairdressing device. The housing is provided with a covering portion in the air outlet direction, and the projection of the covering portion in the opposite direction of the air outlet direction covers the air guide away from the air inlet end. Through the setting of the covering portion, the airflow guided by the end of the air guide cannot be effectively circulated under the obstruction of the covering portion, and the projection covering area will be full of air, making it difficult for subsequent airflow to enter the projection covering area, thereby effectively solving the problem of noise generated by airflow hitting the wall surface of the projection covering area, and improving the consumer experience.

[0002] A hair dryer is a small personal care appliance that can quickly dry hair. It can heat the hair through a heating wire to make the wind hot, thereby drying the hair faster.

[0003] The working principle of the air duct structure of the existing air duct is as follows: the air flow enters the air supply duct from the air inlet. When the air flow reaches the bottom of the air outlet, the air guide in the air supply duct guides the air flow to change direction and blow out from the air outlet. However, part of the air flow will still hit the wind shield wall perpendicular to the air inlet direction, thereby generating a lot of noise and reducing the consumer experience.

[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0033] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0034] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0035] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0036] See also Figures 1 to 6 As shown, the present application provides a noise reduction air duct structure, including a shell 10 with an air supply duct 11 and an air guide 20 arranged in the air supply duct 11 and changing the direction of the air flow. The air flow enters from the air inlet 12 of the air supply duct 11, and is blown out from the air outlet 13 after being guided by the air guide 20.

[0037] The housing 10 is provided with a covering portion 102 in the air outlet direction, and the projection of the covering portion 102 in the opposite direction of the air outlet direction covers the air guide 20 away from the air inlet end (i.e., the end of the air guide 20), and the area projected and covered by the covering portion 102 in the air supply duct 11 is a projection covering area 101 (such as Figure 5 shown).

[0038] Due to the setting of the covering portion 102, the airflow guided by the end of the air guide member 20 cannot be effectively circulated due to the obstruction of the covering portion 102, and the projection covering area 101 will be filled with air, making it difficult for subsequent airflow to enter the projection covering area, thereby effectively solving the problem of noise generated by the airflow hitting the wall of the projection covering area 101 and improving the consumer experience.

[0039] In one embodiment, the air inlet direction of the air inlet 12 is perpendicular to the air outlet direction of the air outlet 13, that is, the air inlet 12 and the air outlet 13 are arranged at a 90° angle. Of course, the air inlet direction of the air inlet 12 and the air outlet direction of the air outlet 13 can also be arranged at other angles, without limitation.

[0040] For example, the cover portion 102 is in the shape of a flat plate, which has a good blocking effect on the airflow. Of course, the cover portion 102 near the air outlet end can also be set to be inclined toward the direction of the air supply duct 11, which also has a good blocking effect on the airflow. The shape of the cover portion 102 is not limited, as long as it can block the wind at the end of the air guide 20.

[0041] A windshield is provided in the air supply duct 11 in a vertical direction along the air inlet direction. The horizontal distance between the windshield and the covering portion 102 close to the air outlet is A. The value of A is not limited as long as the air outlet direction of the projection covering area 101 can be covered.

[0042] Of course, the larger the length A value of the covering portion 102 is, the larger the area of ​​the projected covering area 101 can be understood to be. When the covering portion 102 is long enough, even if the airflow in the air supply duct 11 is accelerated, the projected covering area 101 has enough space to buffer the accelerated airflow, thereby effectively reducing noise.

[0043] In one embodiment of the present application, the wind shield wall is the first wall 103 of the air supply duct 11, and the end edge 131 of the air outlet 13 is integrally connected with the first wall 103 to form the covering portion 102. The length of the covering portion 102 is A, which is understood to be a part of the shell 10 of the covering portion 102.

[0044] Of course, in another embodiment, the covering portion 102 can also be detachably provided on the housing 10 , and the covering portion 102 serves as a separate component to cover the end of the air guide member 20 .

[0045] In another embodiment of the present application, the wind shield wall is an wind guide wall 201 of the wind guide member 20 away from the air inlet end, and the airflow at the end will be guided by the wind guide wall 201 to blow toward the covering part 102, and the horizontal distance between the wind guide wall 201 and the end edge 131 of the air outlet 13 is A.

[0046] Exemplarily, the projection covered area 101 can be understood as the area of ​​the air supply duct 11 that is bounded by the end edge 131 of the air outlet 13 and is far away from the air inlet 12 as the projection covered area 101 .

[0047] like Figure 5 As shown, in one embodiment of the present application, the windshield wall has a first end point 104 close to the air inlet 12 and a second end point 105 far from the air inlet 12, and the horizontal distance between the first end point 104 and the end edge 131 of the air outlet is B, and B is smaller than A, so that the airflow can be effectively prevented from hitting the windshield wall, achieving a good noise reduction effect. When the windshield wall is the first wall 103, the first end point 104 is connected to the bottom wall 111 of the air supply duct 11, and the second end point 105 is connected to the inner wall of the cover portion 12. When the windshield wall is the wind guide wall 201, the first end point 104 and the second end point 105 are respectively two ends of the wind guide wall 201.

[0048] In one embodiment of the present application, the first wall 103 is in an arc shape or a slope shape, which can guide the airflow.

[0049] like Figure 3 As shown, in another embodiment, the first wall 103 is a vertical plane, and the horizontal distance between the first wall 103 and the end edge 131 of the air outlet 13 is the length A of the covering portion 102 .

[0050] When the first wall 103 is a vertical plane, the projection covering area 101 needs to be designed with a sufficiently long space (ie, the length A is sufficiently long) to prevent the airflow from hitting the first wall 103 .

[0051] like Figure 5 As shown, the positioning wall 202 of the air guide 20 facing the first wall 103 is adapted to the shape of the first wall 103, and the positioning wall 202 is positioned against the first wall 103, that is, the air guide 20 is inserted into the air supply duct 11, and no additional components are required to fasten the two, which effectively reduces the cost and is convenient for assembly. Of course, the first wall 103 and the positioning wall 202 may not be in contact, and the air guide 20 may be arranged in the air supply duct in other connection methods.

[0052] Furthermore, in another embodiment, the air guide member 20 may also be a component integrally formed in the air supply duct 11. In this case, the shell 10 needs to be made into a split type, that is, the shell 10 is assembled into two half shells.

[0053] like Figure 1 As shown, in one embodiment of the present application, the housing 10 is an integrated housing 10 structure. Compared with the conventional split assembly housing structure, the integrated housing structure saves the sealing ring used in the half-shell assembly, thereby reducing the cost. At the same time, the integrated housing structure has better airtightness.

[0054] The air guide 20 is an integrated molding structure, and the air guide 20 is inserted into the air supply duct of the integrated housing and corresponds to the air outlet position. The integrated housing structure cooperates with the integrated air guide 20 structure, and the assembly is more convenient.

[0055] like Figure 6 As shown, the present application also provides a hairdressing device, including the noise reduction air duct structure 1. The hairdressing device can be a hair dryer, or a hair dryer with a hair straightening function. Since the hairdressing device adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0056] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
