Problems solved by technology

However, this special protective treatment requires the addition of many parts, resulting in a very complicated structure of the fan
Moreover, in the prior art, the connection and positioning of fans with special protective treatment are mostly through rigid connection, which is not conducive to buffering the high-frequency vibration of the fan and reducing and reducing the noise caused by vibration

Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] combine first Figures 1 to 4 The fan device 10 according to the first embodiment of the present invention will be described. like figure 1 As shown, the fan device 10 includes a housing 2 and a fan vibration source 1 installed in the housing 2 . The fan vibration source 1 is, for example, a motor of a fan device. Those skilled in the art can easily understand that the blower device 10 also includes some other conventional components, which are well known in the art, and a detailed description thereof is omitted here.

[0035] According to the present invention, the fan vibration source 1 is provided with a positioning buffer 3 on its top, and is connected to the inner side of the top wall of the casing 2 through the positioning buffer 3 . In this example, if Figure 4 Shown more clearly, the positioning buffer 3 may comprise a posi...

Abstract

The invention discloses a fan device and a ventilator including the fan device. The fan device includes a casing, a fan vibration source arranged in the casing, and a buffer assembly for associating the fan vibration source with the casing, wherein the The shock absorbing assembly includes at least two of a positioning buffer associated with the top of the fan vibration source, a connection buffer at least partially housing the fan vibration source, and a support buffer associated with the bottom of the fan vibration source. The fan device can effectively buffer the vibration of the fan, reduce and lower the noise transmission, and has a simpler structure.

Description

technical field [0001] The invention belongs to the technical field of small fans, and in particular relates to a fan device, especially a fan device mechanism with an improved damping function. The invention also relates to a ventilator comprising such a blower device. Background technique [0002] The blower is an important part of the ventilator, which is used to generate breathable gas for delivery to the patient. During high-speed rotation, the fan blades cut the air at high speed and generate airflow vibrations. This airflow vibration is transmitted to the fan. Therefore, the fan will generate high-frequency vibration when it is running at high speed. The frequency and amplitude of this vibration propagate outward, causing many secondary damages, such as reduced service life of product components, vibration and noise radiated from equipment, etc. [0003] In order to minimize the secondary damage in the product, it is necessary to do special protection for the vibr...
