[0035] 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.
[0036] 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.
[0037] 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.
[0038] 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.
[0039] See also Figures 1 to 5 , as shown, the present application provides an air duct structure, including a housing 10 and an air guide 20 disposed in the housing 10, wherein the housing 10 is an integrated housing 10 structure, and an air supply duct 11 is formed inside, and air flow enters from an air inlet 12 of the air supply duct 11, and is blown out from an air outlet 13 after passing through the air supply duct 11. The air guide 20 is inserted into the air supply duct 11, and the air guide 20 guides the air flow to the air outlet 13.
[0040] During assembly, the air guide member 20 is inserted into the air supply duct 11 from the air inlet 12, and moved away from the air inlet 12. When the air guide member 2 cannot move in the air supply duct 11, it indicates that the air guide member 20 has been inserted into place.
[0041] By molding the air guide 20 and the shell 10 separately and then inserting the air guide 20 into the shell 10, compared with the traditional assembled shell structure, which requires a sealing ring to be set between the two half shells, the one-piece shell structure does not need to assemble a sealing ring, thereby reducing costs and having better sealing, effectively reducing the loss of blowing kinetic energy.
[0042] Optionally, the air inlet 12 and the air outlet 13 are arranged at a vertical angle, and the air guide 20 changes the flow direction of the airflow, thereby blowing the airflow out from the side of the shell 10.
[0043] like Figure 2 and Figure 4 As shown, in one embodiment of the present application, the air supply duct 11 includes an air inlet section 111 and an air outlet section 112 which are connected to each other, and the diameter of the air inlet section 111 is larger than the diameter of the air outlet section 112. The diameter of the air inlet section 111 is set larger than the diameter of the air outlet section 112, so as to facilitate demolding of the mold when forming the shell 10.
[0044] like Figure 2 and Figure 4 As shown, optionally, the air inlet section 111 is higher than the air outlet section 112, forming a height difference between the two. The height difference is transitionally connected by a smooth curved surface 115. The setting of the smooth curved surface 115 allows the air inlet section 111 and the air outlet section 112 to transition smoothly and connect. Since there are no angles at the connection position that may cause abnormal noise, the wind resistance and noise can be greatly reduced.
[0045] Exemplarily, the air inlet section 111 is cylindrical and is used to accommodate the installation of a motor and a heating element. When the motor blows air, the air flows into the air supply duct 11 from the air inlet 12 and is then blown out from the air outlet through the air guide 20 .
[0046] like Figure 3As shown, in one embodiment of the present application, the outer wall of the air guide member 20 is positioned in abutment with the inner wall of the air outlet section 112, and the air guide member 20 is positioned and installed in the air outlet section 112 without the need for additional connecting components, thereby saving costs and avoiding the problem of poor airtightness caused by drilling holes in the shell 10.
[0047] like Figure 2 and Figure 3 and Figure 4 As shown, optionally, the air guide 20 includes two positioning plates 21 and a plurality of air guide pieces 22 spaced between the two positioning plates 21. The air guide pieces 22 may be arc-shaped to facilitate the flow and direction change of the airflow. The side outer walls 211 of the two positioning plates 21 are in contact with the inner walls 113 on both sides of the air outlet section 112, and the rear end outer wall 221 of the end air guide piece is in contact with the rear end inner wall 114 opposite to the air inlet 12 for positioning. The multiple outer walls of the air guide 20 are in contact with the multiple inner walls of the air outlet section 112, and the two form a stable mounting structure.
[0048] like Figure 2 and Figure 3 As shown, in one embodiment of the present application, the air guide member 20 also includes a positioning rib 23 connected to the middle bottom surface of the plurality of air guide plates 22, the bottom surface of the positioning rib 23 is in contact with the bottom inner wall of the air outlet section 112 for positioning, the positioning rib 23 plays a supporting role, and the bottom surface of the air guide member 20 is only in contact with the bottom inner wall of the air outlet end 112 through the positioning rib 23, which effectively reduces the contact area between the two, making the air guide member 20 smoother when inserted into the air supply duct 11, and more convenient to assemble.
[0049] Optionally, a slide groove adapted to the positioning ribs 23 may be recessed on the bottom inner wall of the air supply duct 11 to make the positioning ribs 23 more smoothly inserted and positioned.
[0050] like Figure 2 As shown, in one embodiment of the present application, the air guide blades 22 extend obliquely along the air flow direction, and along the air flow direction, the inclination angle of each air guide blade 22 gradually increases. The inclined air guide blades 22 allow the air flow to be evenly dispersed and blown out from the air outlet, and the larger the inclination angle, the better the effect of air flow diffusing outward.
[0051] like Figure 1 As shown, in one embodiment of the present application, the air outlet 13 is in an elongated shape, and the elongated air outlet 13 can ensure both the air flow velocity and the air flow rate. The air outlet 13 passes through the upper and lower inner walls of the air outlet section 112 and is arranged in the middle of the mounting outer surface 102 of the air outlet section 112. Of course, two or more elongated air outlets 13 can be provided.
[0052] like Figure 4 As shown, in one embodiment of the present application, both sides of the installation outer surface 102 extend out of the outer walls of the air outlet section 112 to form an extension portion 103, and the upper and lower surfaces of the extension portion 103 are penetrated to form a drainage hole 104. The drainage hole drains the moisture on the installation outer surface 102, which can effectively prevent moisture from entering the air supply duct 11 from the air outlet 13, thereby avoiding short circuits caused by components.
[0053] like Figure 1 , 2 As shown in FIG. 4 , in one embodiment of the present application, a connection position 105 for connecting the shell 10 to the outer shell 2 is provided on the outer wall of the shell 10. Optionally, the connection position 105 can be a through hole, and the shell 10 is locked to the outer shell 2 by passing a screw through the through hole. Of course, the connection position 105 can also be other connection structures, such as a snap connection structure, a latch connection structure, etc.
[0054] like Figure 5 As shown, the present application also provides a hairdressing device, including the air duct structure 1, which 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.
[0055] 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.
