Detailed Implementation

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0028] Example 1

[0029] like Figures 2-5 As shown, this embodiment proposes an air outlet swing mechanism, mainly applicable to various household, commercial, and industrial appliances. The main structure includes an air outlet grille 1 for decoration and adjusting the airflow direction, supported by a matching duct support. The duct support has an air outlet end 23 for media flow. The air outlet grille 1 covers the air outlet end 23, and one side of the air outlet grille 1 is rotatably connected to the duct support. When adjusting the airflow direction, the user can simply swing the air outlet grille 1, making operation simple. No other structures are required on the surface of the air outlet grille 1, resulting in a clean and aesthetically pleasing design. Furthermore, this embodiment also includes a self-positioning structure for fixing the swing angle of the air outlet grille 1. After adjusting the position of the air outlet grille 1, the user only needs to release it, and the air outlet grille 1 will automatically fix itself.

[0030] Specifically, the air duct support in the embodiment is divided into an upper support 21 and a lower support 22 located at the upper and lower parts of the air outlet grid 1 respectively. The lower support 22 has two side plates, and the rotating shaft 224 is arranged on each side plate. The air outlet grid 1 is sleeved on the rotating shaft 224 and is rotationally connected with the rotating shaft 224 to realize the swing of the air outlet grid 1. The self-positioning structure includes the elastic damping rod 3 (preferably made of elastic metal material, long service life and stable performance) and the limiting groove 11 arranged on the two sides of the air outlet grid 1. For the convenience of setting, the side plate is arranged on the side of the air outlet grid 1 in the embodiment, and the protruding rib is arranged on the side plate to form the limiting groove 11 and improve the structural strength of the air outlet grid 1. The limiting groove 11 on each side of the air outlet grid 1 has at least two, and the two limiting grooves 11 on each side are located on the two sides of the center axis of the rotating shaft 224. Then, two groups of elastic damping rods 3 are arranged, and the two ends of the elastic damping rod 3 are embedded in the limiting groove 11. The circumference of the rotating shaft 224 is in abutment with the elastic damping rod 3 and is pressed to be bent. The elastic deformation restoring force of the elastic damping rod 3 generates resistance with the circumference of the rotating shaft 224 to realize the automatic fixing of the air outlet grid 1. When the air outlet grid 1 needs to be swung, the user only needs to exert an external force to offset the frictional resistance generated between the elastic damping rod 3 and the circumference of the rotating shaft 224 to swing the air outlet grid 1. In order to ensure the service life and reduce the wear of the rotating shaft 224 caused by the elastic damping rod 3, the rotating shaft 224 is preferably made of high-strength wear-resistant material, which is not limited in the embodiment.

[0031] Since the swing center of the air outlet grid 1 is arranged at the upper part in the embodiment, in order to avoid the gap generated at the lower part of the air outlet grid 1 after swinging and cause the air leakage of the electrical equipment, the arc-shaped wind baffle 15 is arranged at the lower part of the air outlet grid 1 to prevent the air leakage of the air outlet grid 1 during swinging. Specifically, the arc-shaped wind baffle 15 extends from the side close to the air outlet grid 1 to the side away from the air outlet grid 1, and the extension length needs to cover the maximum swing angle of the air outlet grid 1. The end of the arc-shaped wind baffle 15 away from the air outlet grid 1 is provided with the limiting block 13 for abutting against the inner side of the lower support 22 or the inner side of the shell of the electrical equipment to control the maximum swing angle of the air outlet grid 1 to the outside, and the swing angle of the air outlet grid 1 is controlled within a safe range (0-35°) to avoid the damage of the structural parts caused by the over operation.

[0032] Meanwhile, the upper support 21 of the air outlet grille 1 is additionally provided with an upper cover 14 of arc structure concentric with the rotating shaft 224 at one end of the upper support 21, rotating holes 12 for embedding the rotating shaft 224 are formed on both sides of the upper cover 14, the rotating holes 12 are two and are formed on both sides of the upper cover 14, and are connected and matched with the two rotating shafts 224 respectively, so that the structural stability of the air outlet grille 1 is improved. The upper support 21 is provided with an upper arc-shaped limiting cover 211 concentric with the upper cover 14, which plays an auxiliary limiting role. When the air outlet grille 1 rotates, the upper cover 14 is matched with the shell of the electric appliance, so as to avoid shielding and decoration, and avoid the hollow between the top of the air outlet grille 1 and the shell of the electric appliance, which affects the overall appearance of the electric appliance. The surface of the upper arc-shaped limiting cover 211 can abut against the surface of the upper cover 14 to form a sliding connection relationship, or a gap is matched, then the arc-shaped wind deflector 15 is concentric with the rotating shaft 224, which plays an auxiliary limiting role and facilitates the normal swinging of the air outlet grille 1. The lower support 22 is additionally provided with a lower arc-shaped limiting cover 223 concentric with the arc-shaped wind deflector 15, which plays an auxiliary limiting role and limits the degree of freedom of the air outlet grille 1 when swinging, so as to improve the stability of the embodiment. Similarly, the surface of the lower arc-shaped limiting cover 223 can abut against the arc-shaped wind deflector 15 to form a sliding connection relationship, or a gap can be reserved, which facilitates the movement of the air outlet grille 1.

[0033] The limiting baffle 222 can be integrally formed with the lower arc-shaped limiting cover 223, and is bent downward and rearward to form an included angle with the lower arc-shaped limiting cover 223. The end of the lower arc-shaped limiting cover 223 close to the air outlet grille 1 is matched with the downward side of the limiting baffle 222, and can abut against the side of the arc-shaped wind deflector 15 away from the air outlet end 23. Meanwhile, the limiting baffle 222 plays a limiting role of preventing the air outlet grille 1 from being excessively reset, avoids swinging to a negative angle, and has compact structure, high integrity and convenient assembly.

[0036] The appearance of the fan heater is beautiful and simple, the adjustment of the air outlet direction is convenient, and the air outlet grille 1 can be automatically fixed to any angle.

[0037] The above is only the preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
