Abstract
The utility model relates to an indoor exhaust apparatus, which comprises wind ports, a wind pipe, a vent, a venting pipe, wind port covers and a stay cord, wherein the indoor exhaust apparatus is integrally in a 'T'-shape, a horizontal pipe is the wind pipe, two ends of the wind pipe are respectively provided with the horn-shaped wind port, the inner of the wind pipe is provided with an air channel, a vertical pipe is the venting pipe, the venting pipe is communicated with the wind pipe, and the lower end of the venting pipe is provided with the vent, when the apparatus is not in use, for preventing sand wind from mixing into chamber wind, the wind ports on two ends are respectively provided with the wind port cover, the wind port covers are linked with the wind ports through hinges, and offsetting springs are allocated on the wind port covers, when the apparatus is not in use, the wind port covers are automatically in a closed state, when the apparatus is in use, the wind port covers are pulled to be open through the stay cord. Since natural wind is almost in the north-and-south wind direction, the indoor exhaust apparatus is arranged in a room in the north-and-south direction, and the wind ports face to the outside.
Description
Technical field
The utility model relates to a kind of indoor exhaust device, and it is used for the gas extraction system of factory floor, plant or family's operation room.
Background technology
Vented exhaust all will often be carried out in kitchen in factory floor, large-scale plant and family, to get rid of indoor dirty gas or oil smoke, existing technology adopts the electric fan exhaust more, and its shortcoming is: the one, need the electrical equipment equipment, consumed power, expense are higher relatively; The 2nd, exhaust outlet the problem of exhaust problem can occur facing one direction in the time of against the wind.Factory floor that has or operation room have adopted automatic fan exhaust, and fan is loaded on the roof blows fan rotation exhaust by natural wind, though this method can be saved electric energy, the reduction expense, but exhaust capacity is low, and effect is not fine.
Summary of the invention
The utility model overcomes the deficiency of above technical existence, according to the principle of continuity in the equation and bernoulli's equation (in gas and liquid, the position pressure that flow velocity is big more is more little), design a kind of indoor exhaust device that utilizes the mobile pump drainage indoor gas of natural wind.
The purpose of this utility model is achieved through the following technical solutions: a kind of indoor exhaust device, comprise by air port, airduct, exhaust outlet, blast pipe, stock cap, stay cord and forming, described indoor exhaust device, integral body is " T " font, horizontal tube is an airduct, a tubaeform air port is respectively established at the two ends of airduct, and there is the air channel inside of airduct; Vertical tube is a blast pipe, and blast pipe communicates with airduct, and exhaust outlet is established in the lower end of blast pipe; Not the time spent, seal in chamber wind for preventing dust storm, a stock cap is respectively established in the air port, two ends, and stock cap connects with the air port by hinge, is furnished with back-moving spring on the stock cap, and the time spent is not automatic closed condition, by stay cord stock cap is drawn back during use.Because natural wind mostly is the north and south wind direction, be installed on indoorly so the indoor exhaust device is North and South direction, the air port is towards outdoor.
When using the utility model, by stay cord stock cap is drawn back, if wind direction is blowed southward by north, then the north wind mouth is an air inlet, the south wind mouth then is an air outlet, if wind direction blows from south orientation north, south wind mouth air intake then, the air-out of north wind mouth, wind is flow at high speed in the air channel, because air velocity is big in the air channel, so a low-pressure area occurs in the blast pipe air channel relatively, indoor gas can be discharged with the air channel.The utility model is suitable between factory, plant and domestic hygiene and use in the kitchen.
The utility model is simple in structure, cheap, energy saving, good exhaust effect, can extensively promote the use of.
Description of drawings
Accompanying drawing is the utility model structural representation.
Wherein: 1, air port 2, airduct 3, exhaust outlet 4, blast pipe 5, stock cap 6, stay cord
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, a kind of indoor exhaust device, comprise by air port 1, airduct 2, exhaust outlet 3, blast pipe 4, stock cap 5, stay cord 6 and forming, indoor exhaust device integral body is " T " font, horizontal tube is an airduct 2, a tubaeform air port 3 is respectively established at the two ends of airduct 2, and there is the air channel inside of airduct 2; Vertical tube is a blast pipe 4, and blast pipe 4 communicates with airduct 2, and exhaust outlet 3 is established in the lower end of blast pipe 4; Not the time spent, seal in chamber wind for preventing dust storm, a stock cap 5 is respectively established in air port, two ends 1, and stock cap 5 connects with air port 1 by hinge, is furnished with back-moving spring on the stock cap 5, and the time spent is not automatic closed condition, by stay cord 6 stock cap 5 is drawn back during use.Because natural wind mostly is the north and south wind direction, be installed on indoorly so the indoor exhaust device is North and South direction, air port 1 is towards outdoor.
