Embodiment Construction

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the implementation manners in the present invention, all other implementation manners obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0036] It should be noted that when a component is said to be "mounted on" another component, it may be directly mounted on another component or there may be an intervening component. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time. When a component is said to be "fixed" to another component, it may be directly...

Abstract

The invention provides an axial flow fan with shock absorption and noise reduction functions, and belongs to the technical field of machinery. The problem of poor stability in the prior art is solved. The axial flow fan with the shock absorption and noise reduction functions comprises a fan body and a support connected to the lower portion of the fan body and further comprises a supporting plate, a first shock absorption piece, a second shock absorption piece and a circumferential positioning structure, the supporting plate is connected to the lower portion of the fan body, and the first shock absorption piece is located between the supporting plate and the fan body; the support is cylindrical, the fan body is embedded in the support, the lower portion of the supporting plate abuts against the inner side of the support, the second damping piece is located between the support and the supporting plate, and the circumferential positioning structure is located between the upper portion of the fan body and the support. The axial flow fan with the shock absorption and noise reduction functions is high in stability.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to an axial flow fan with the function of shock absorption and noise reduction. Background technique [0002] The axial flow fan is widely used, and it outputs the air flow in the axial direction stably. [0003] Existing axial flow fans usually include a cylindrical casing and a motor and an impeller connected in the casing. The motor drives the impeller to continuously rotate, and can stably and continuously deliver fast airflow in the axial direction. [0004] The axial flow fan will vibrate due to the rotation of the impeller during use, and the greater the power of the fan, the more obvious the vibration will be. In order to solve this problem, a flexible shock absorber is usually used directly between the shell and the connection to achieve shock absorption. Because the shock absorber is directly exposed, its structure is not compact, and the exposed shock absorber is easy to...
