Problems solved by technology

[0006] However, in the existing baffle type cutting device, the baffle plate is formed of a thin resin plate, which has weak heat retention and hardly works in cold regions.
[0007] The airtightness of the existing baffles is not guaranteed, and the use of baffles in China, where the smog is severe, cannot completely block the smog flying into the house, so there is also the risk of indoor pollution by smog

Embodiment Construction

[0060] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can easily implement them.

[0061] Such as Figure 1 to Figure 4 As shown, the structure of the exhaust fan cutter 100 of the present invention includes:

[0062] The air discharge port 13 that air is discharged in the exhaust fan casing 10 that is provided with the fan 12 that rotates by the motor 11 and sucks the internal air is extended and set, and is fixedly arranged on the inner wall to form an air channel 111 that the internal air is discharged to the outside frame 110;

[0063] A cut-off ridge 120 protruding from the inner side of the frame 110;

[0064] a central axis 130 movably disposed at the center of the frame 110;

[0065] A cut-off plate 140 formed corresponding to the cut-off ridge 120, fixedly arranged on the central axis 130, connected to the cut-off ridge 120 through the movement of the c...

Abstract

The present invention relates to a blocking device coupled to a ventilator and, more specifically, to a blocking device for a ventilator, the blocking device comprising: a frame extending from an airdischarge port of a ventilator case having a fan which is rotated by a motor to suction inside air; an air passage formed by the frame to discharge the inside air to the outside therethrough; and a blocking plate mounted on a central shaft movably installed at the center of the frame. The blocking plate allows the inside air to be discharged when the blocking plate is pushed backward by the pressure of discharged air. When the fan does not rotate, the blocking plate and a blocking bump protruding from the inner surface of the frame are engaged with each other to block the air passage to prevent inner heat from being discharged and external air from being introduced.

Description

technical field [0001] The present invention relates to a disconnector combined with an exhaust fan. Specifically, an air passage for discharging internal air to the outside is formed by extending a frame on the air discharge port of an exhaust fan casing provided with a fan that utilizes a motor to rotate to suck in internal air, thereby enabling The cut-off plate assembled on the central shaft in the center of the frame is pushed to the rear by the pressure of the exhaust air to discharge the internal air to the outside. A cut-off device for an exhaust fan that engages and seals the air passage to cut off the outflow of internal heat and the inflow of external air. Background technique [0002] Usually the exhaust fan is installed on the hole that passes through the wall or the window, and the fan is rotated by a motor to exhaust the internal air to the outside. [0003] The defect of this exhaust fan is that outside cold air, dust, noise, peculiar smell etc. enter in the...
