Problems solved by technology

However, because the wind of this type of fan needs to be generated by the high-speed rotating impeller hidden in the base, the superposition of wind noise and motor vibration noise makes it difficult for the noise of the entire fan to meet the requirements of consumers.

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] see figure 1 with figure 2 , a fan assembly, including a base 1, a fan 4 arranged in the inner cavity of the base, and a nozzle 3 connected to the base 1. The nozzle 3 extends upwards from both sides of the seat body 1 in an arc-shaped band shape and closes on the top of the nozzle, including a straight portion 302 and an arc portion 303 whose upper end is closed. The arc portion 303 extends backward in an arc shape. An internal passage 304 is provided inside the nozzle 3 , and a mouth 301 extending along the edge is provided at the rear of the nozzle 3 , the opening of the mouth 301 communicates with the internal passage 304 and points forward.

[0024] A base 2 is provided outside the seat body 1 . The base 2 includes side portions 201 connected to two sides of the base body 1 and a supporting portion 202 extending from one side of the bas...

Abstract

The invention discloses a fan assembly which comprises a spray nozzle and a draught fan used for generating air flow in the spray nozzle, wherein the spray nozzle comprises an inner channel and a nozzle part which is communicated with the inner channel and used for jetting the air flow; the draught fan is arranged on a base body through a shock absorbing mechanism; the shock absorbing mechanism comprises a first elastic pad arranged between the fan and the base body; and the first elastic pad is provided with at least one S-shaped elastic part which is connected on the inner wall of the base body. The shock absorbing structure of the S-shaped elastic part is arranged between the draught fan and the base body, so that greater vibration buffering range is achieved, and therefore, vibration noises generated by operation vibration of the draught fan can be effectively reduced.

Description

technical field [0001] The present invention relates to an electric fan, in particular to a fan assembly without blades, which includes a nozzle and a fan for generating airflow in the nozzle; the nozzle includes an internal channel and communicates with the internal channel and sprays Airflow mouth. Background technique [0002] Bladeless electric fans are becoming more and more popular in the market because of their better safety and unique air outlet mode. The wind of this type of fan needs to be generated by the rotating impeller hidden in the base. For example, the Chinese utility model patent with the notification number CN201884311U discloses a fan assembly for generating airflow, and the fan assembly includes a nozzle installed on a base. The base includes an outer housing; an impeller housing housed within the outer housing, the impeller housing having an air inlet and an air outlet; an impeller within the impeller housing; and driving the impeller to generate air...
