[0001] The utility model belongs to fan technical field, especially relate to a shock attenuation type neck fan. BACKGROUND

[0002] With the popularity of portable electronic equipment, the neck fan as a new type of personal cooling equipment has been widely used in recent years. The neck fan provides continuous cool wind for the user by hanging on the neck, and is suitable for various scenes such as outdoor activities and office environment.

[0003] In order to ensure the air outlet efficiency of the neck fan, the internal fan usually needs to run at a high speed. However, when the internal fan rotates at high speed, vibration of different degrees will be generated. When the fan rotates at a high speed, the vibration will be transmitted to the user's neck through the shell of the neck fan, causing the wearer to feel uncomfortable and also producing additional noise.

[0009] In the present application, the fan is a straight cylinder type fan.

[0010] The material of the shock attenuation sleeve can be silica gel, rubber sleeve, polyurethane, etc.

[0011] The air duct can be formed by the inner cavity of the neck frame, or an air duct pipe can be arranged in the neck frame to form the air duct.

[0012] The fixing mode between the shock attenuation sleeve and the neck frame can be glue fixing, pressing the shock attenuation sleeve with the two side walls of the neck frame, or fixing the shock attenuation sleeve and the neck frame through other components.

[0013] The scheme can reduce the vibration of the shell and noise, thereby improving the comfort of the wearer during use.

[0014] As a preferred, the neck-wearing frame comprises side shells constituting left and right sections of the neck-wearing frame and a rear shell constituting a rear section of the neck-wearing frame, and the air duct comprises a side air duct in the side shell and a rear air duct in the rear shell; a duct pipe is fixed in the side shell, an inner cavity of the duct pipe forms the side air duct, and the duct pipe is arranged separately from the fan and connected to the fan through the shock-absorbing sleeve.

[0015] The duct pipe can better guide the wind generated by the fan, the duct pipe and the fan are arranged separately and connected through the shock-absorbing sleeve, so that the vibration of the fan is indirectly transmitted to the duct pipe through the shock-absorbing sleeve when the fan rotates, the shock-absorbing sleeve weakens the vibration, reduces the influence of the fan on the duct pipe, and improves the comfort of the wearer.

[0016] As a preferred, the shock-absorbing sleeve is provided with an annular connecting portion extending to the side of the duct pipe near the end of the duct pipe, and the end of the duct pipe is sleeved on the annular connecting portion and abuts against the end of the shock-absorbing sleeve.

[0017] The annular connecting portion facilitates the connection between the duct pipe and the shock-absorbing sleeve, and the connection mode can be fixed with glue, fixed with threads, plug-in cooperation, etc.

[0018] As a preferred, the outer wall of the shock-absorbing sleeve is provided with a plurality of annular protrusions uniformly and spaced apart in the axial direction of the shock-absorbing sleeve.

[0019] The annular protrusions further improve the shock-absorbing effect of the shock-absorbing sleeve.

[0020] As a preferred, the shock-absorbing sleeve is matched with a C-shaped fixing ring, the fixing ring is sleeved on the outside of the shock-absorbing sleeve, and the fixing ring is fixedly connected between the neck-wearing frame to fix the shock-absorbing sleeve and the neck-wearing frame.

[0021] The C-shaped fixing ring is a simpler way to fix the shock-absorbing sleeve and the neck-wearing frame, and the fixed connection mode of the C-shaped fixing ring and the neck-wearing frame can be screw fixing, buckle fixing, etc.

[0022] As a preferred, the neck-wearing frame is composed of two mutually cooperating shells, and the two mutually cooperating shells can clamp and fix the shock-absorbing sleeve.

[0023] The shock-absorbing sleeve is directly fixed in a clamped manner by the two shells of the neck-wearing frame, and no lock screw is needed, which is simple and convenient.

[0024] Preferably, the internal diameter of the air duct gradually decreases along the airflow direction.

[0025] The above settings are used to achieve the convergence and acceleration of airflow.

[0026] Preferably, the rear housing is rotatably connected to the two side housings. The rear housing is hollow and has a baffle extending along its length and dividing the inner cavity of the rear housing into an upper cavity and a lower cavity. The lower cavity forms the rear air duct, and the end of the air duct is aligned with the lower cavity.

[0027] The rear shell is divided into an upper cavity and a lower cavity by a baffle, and only the lower cavity is aligned with the air duct to reduce the diameter of the air duct, thereby ensuring that the air speed blown out by the rear shell is greater and improving the wearer's comfort during use.

[0028] Preferably, the aperture at the end of the lower cavity along the airflow direction is smaller than the aperture at the beginning of the lower cavity along the airflow direction.

[0029] Furthermore, the aperture of the lower cavity along the airflow direction is reduced to ensure that the airflow reaches the back of the wearer's neck, thereby improving the wearer's comfort during use. This reduction in aperture size can be achieved by bending the baffle towards the lower cavity, or by altering the thickness of the baffle.

[0030] Compared with the prior art, this utility model has the advantage of reducing fan casing vibration and noise, thereby improving the user's comfort during use. Attached Figure Description
