Abstract

The utility model relates to a ventilation water-isolating device of glass, which is characterized in that the ventilation water-isolating device of glass comprises an outer case 1, an inner case 2 and a spring 3. An air intake hole 4 is arranged on an end face of the outer case 1facing outside, an air outlet hole 5 is arranged on a side of the inner case 2, the spring 3 is arranged in the inner case 2, an end face of the case 2 facing inside is sealed. A resistance board 6 is arranged in the front of the spring 3. A plurality of ventilation holes 7 are arranged on the resistance board 6. The bottom of inner wall of the inner case 2 has outward lean. The ventilation water-isolating device can ventilate naturally when a window is closed and can isolate water when it rains.

Description

Glass ventilation water stop

The utility model relates to a kind of device that is used for glass window ventilation water proof.

When existing glass window cuts out, indoor stuffy; After opening, if the people forgets the pass window when leaving, run into when blowing, raining, the water into room that will waft drenches floor and furniture.

The purpose of this utility model provides a kind of glass ventilation water stop, when not windowing, indoor can be ventilated, run into when blowing, raining, it plays impermeable role again.

The purpose of this utility model is achieved in that

A kind of glass ventilation water stop, comprise: outer box, inner box, spring assembly, outer box towards outdoor end face fresh air inlet is arranged, there is exhaust vent the side of inner box, inner box towards indoor end face one sealing plate is arranged, the built-in spring of inner box, one end of spring is stuck in the rear end of inner box, the other end of spring has a flaps, and the aperture that has some to ventilate on the flaps has certain gradient towards outer incline at the bottom of the inner box inwall.

Because outer box of the present utility model has fresh air inlet, and the aperture that can ventilate is arranged on the flaps on the inner box, the inner box sidewall has exhaust vent, when window is closed, can play the effect of natural ventilation.When rainy, can play the effect of water proof.

Below in conjunction with description of drawings the utility model.

Fig. 1 is the utility model inner box and outer box combination schematic diagram;

Fig. 2 is the outer box schematic diagram of the utility model;

Fig. 3 is the utility model inner box schematic diagram;

Fig. 4 is the utility model inner box generalized section.

Shown in Fig. 1,2,3,4, a kind of glass ventilation water stop comprises: outer box 1, inner box 2, spring 3; Outer box 1 towards outdoor end face fresh air inlet 4 is arranged, there is exhaust vent 5 side of inner box 2, inner box 2 towards indoor end face for the sealing, spring 3 is arranged in the inner box 2, one end of spring 3 is stuck in the rear end of inner box 2, and the other end of spring 3 has a flaps 6, and some apertures that can ventilate 7 are arranged on the flaps 6; When having only wind not have rainwater, resistance is little, and wind just can enter inner box 2 by the aperture 7 on the flaps 6, in exhaust vent 5 inlet chambers by inner box 2 sides, has so just realized the function of ventilating; When raining water being arranged, because of the aperture on the water blockage flaps 67, resistance increases, and spring 3 inwardly shortens, and spring 3 has been blocked the exhaust vent 5 of inner box 2 sides, and water can be in exhaust vent 5 inlet chambers just by every outdoor; Wind is big more, and water is many more, and resistance is big more, and the seam between the spring is more little, and water is just difficult more by in exhaust vent 5 inlet chambers; When spring 3 is compressed to when closing up fully, but leave the aperture of some natural ventilations on the limit that spring 3 closes up; Have at the bottom of inner box 2 inwalls necessarily towards the gradient of outer incline, be convenient to draining and go out, rainwater outside inner box 2 delivery chamber, thereby realized the function of ventilation water proof.

Inner box 2 has third gear with outer box 1 relative position, and during box 1 centre position, the utility model is in the state of ventilation water proof outside inner box 2 is in; When inner box 2 when outer box 1 is extracted out, can clean the utility model; When inner box 2 with outside box 1 when closing, the utility model is in the state of sealing.

Inner box 2 of the present utility model, the cross section of outer box 1 can be circle, ellipse, square and other shape.

The utility model may be used on house, car, train and the various place that needs glass window.
