Problems solved by technology

[0004] At this time, the mask made of ABS material will cause residual stress in the process of forming the mask due to the characteristics of ABS. Directly use the mounting screws with permeable chemical substances to drive into the mask, especially if the diameter is smaller. When the screw is 4mm, the stress remaining on the mask will concentrate on the screw, and the ABS material mask will crack and break, which may separate the mask from the ceiling.

Abstract

The invention relates to a fixed structure for a ventilator mask and a spring, which is characterized in that a fixed element is formed integrally with the ventilator mask; a movable element is arranged on the fixed element in a mode of clamping and connecting; and the spring is sleeved on the movable element. No screw is directly acted on the mask, stress can not be generated between the fixed element and the mask, and further the mask can not be damaged, thereby improving the durability of products.

Description

technical field [0001] The invention relates to a ventilation fan, in particular to a fixing structure for installing a ventilation fan mask spring. Background technique [0002] A ventilation fan is a common air circulation device used to remove air from a room. Just disclose a kind of ventilation fan as Chinese patent ZL95211395.3, just describe that two " eight " font spring clips are housed on the inner surface of panel. [0003] Such as figure 1 As shown, the main structure of the ventilation fan includes a motor 1, a volute 2, a support plate 3, a box body 4, an air outlet pipe 5, a panel 6, an air outlet 10, an air inlet 11, etc., and two A "eight"-shaped spring clip 7, two metal sheets 12 with holes are installed at the corresponding place of the casing 4, and the spring clip 7 is put into the holes of the metal sheet 12, so that the panel 6 can be conveniently and firmly fixed on the case 4. [0004] At this time, the mask made of ABS material will cause residua...
