Problems solved by technology

This kind of installation and fixing structure is relatively simple and easy to implement, but when installing the air intake mask, it is necessary to gather the two ends of the "eight"-shaped spring by hand before inserting it into the spring pressing hole of the body. Due to the narrow installation part, the operation is very difficult. Convenient, and prone to injury to the operator due to spring back

Embodiment Construction

[0022] The specific embodiment of the present invention will be described in further detail below in conjunction with accompanying drawing:

[0023] Such as figure 1 , 2 As shown, in this embodiment, the installation structure includes a ventilation fan body 1 , an air intake mask 2 and two independent "eight"-shaped springs 3 .

[0024] As shown in Figures 3 and 4, its air intake mask 2 has two concave "bridge arch" passing holes 4, and the upper side of the passing hole 4 (that is, the back of the air intake mask) hole There is a "bridge arch" cross bar 41 in the middle to separate the crossing hole into two small holes on the left and the right. The spring 3 can be inserted into the left and right small holes.

[0025] As shown in FIG. 5 , two positioning pins 5 are arranged on two opposite corners on the back of the air intake mask, and the positions of the two pins are matched with the assembly parts on the body 1 .

[0026] Such as Figure 6 As shown, the fan is ins...

Abstract

An installation structure for the air inlet scoop of air exchanging fan is composed of a main body of air exchanging fan, an air inlet scoop, and two splayed elastic strips. Its installation method includes such steps as inserting the both ends of said splayed elastic strip through the arched hole on said air inlet scoop and then into the elastic hole on said main body, and inserting locating pins.

Description

technical field [0001] The invention relates to a ventilation fan, in particular to a connection and installation structure between an air inlet mask of the ventilation fan and a machine body and an installation method thereof. Background technique [0002] The air inlet of the body of the ventilation fan usually needs to be installed with an air intake mask, such as a general louver-shaped mask or a grid-shaped mask. A kind of ventilating fan disclosed in Chinese patent ZL95211395.3 just describes that two "eight" spring clips are housed on the inner surface of the panel, and two metal sheets with holes are housed at the box body and its corresponding positions. [0003] At present, the common method of installing and fixing the air intake mask on the ventilator body is to use two "eight"-shaped springs fixed on the back of the air intake mask, and insert them into the two spring pressing holes on the ventilator body respectively. The tension force of this spring makes the...
