Abstract

The utility model relates to a rainwater-proof exhaust device, which comprises a casing. An air hole is formed at the upper end of the casing; an exhaust pipe is connected at the lower end of the casing; a water containing pan is arranged in the casing; a gap is reserved between the inner wall of the casing and the water containing pan; and a plurality of drain pipes communicating the inside of the water containing pan and the outside of the casing are arranged between the bottom of the water containing pan and the casing. Because the water containing pan is arranged in the casing, and the gap is reserved between the water containing pan and the inner wall of the casing, the gas enters from the exhaust pipe at the lower end of the casing can pass through the gap between the water containing pan and the inner wall of the casing, and then goes out from the air hole at the upper end of the casing. The exhaust effect is good. In rainy days, rainwater can fall on the water containing pan from the air hole at the upper end of the casing, and then is drained outside the casing through the drain pipes, therefore, rainwater is prevented from entering exhaust passages or the inside of houses, and the rainwater prevention effect is good.

Description

The rain-proof type exhaust apparatus

Technical field

The utility model relates to a kind of exhaust apparatus, specifically, relates to a kind of rainwater that can prevent and enters exhaust duct or indoor rain-proof type exhaust apparatus.

Background technology

In order to improve IAQ, pollution sources in elimination or the minimizing room air, improve the quality of room air, most economical, the valid approach that is adopted now is ventilation, keep the circulation of room air and fresh by ventilation, drain at any time or dilution chamber contains the foul atmosphere of pollutant and microorganism.

At present, most employing is provided with ventilator at the top of buildings such as warehouse, factory building mode realizes the circulation between the indoor-outdoor air, to reach the purpose of ventilation, the circulation of air in the holding chamber and fresh, ventilator in use, owing to be subjected to the interference of wind-force, gas often takes place pour in down a chimney phenomenon, influence exhaust effect, wait under the bad weather rainy, rainwater takes place easily pour in down a chimney phenomenon, make rainwater enter exhaust duct or indoor, anti-rainwater weak effect.

The utility model content

Problem to be solved in the utility model is at above problem, a kind of good exhaust effect is provided, can prevents effectively that rainwater from entering exhaust duct or indoor rain-proof type exhaust apparatus.

For addressing the above problem, the technical scheme that the utility model adopted is: the rain-proof type exhaust apparatus, comprise housing, described housing upper end is provided with steam vent, described housing lower end is connected with blast pipe, be provided with drip tray in the described housing, have the gap between the inwall of described housing and the drip tray, be provided with the some drainpipes that are communicated with drip tray inside and hull outside between described drip tray bottom and the housing.

A kind of concrete prioritization scheme, described drip tray be shaped as circle.

A kind of concrete prioritization scheme, the excircle of described drip tray is connected with inner walls is tangent.

A kind of concrete prioritization scheme, the area of the projection of described steam vent on the drip tray bottom is less than the area of drip tray bottom.

A kind of concrete prioritization scheme, described housing comprises upper shell and lower house.

A kind of concrete prioritization scheme, the cross section of described upper shell and lower house is respectively rectangle, and the longitudinal section of described upper shell is trapezoidal, and described lower house longitudinal section is for trapezoidal.

A kind of concrete prioritization scheme, the quantity of described drainpipe are four.

The utility model is taked above technical scheme, have the following advantages: owing to be provided with drip tray in the housing, has the gap between drip tray and the inner walls, so, the gas that enters from the blast pipe of housing lower end can pass through from the gap between drip tray and the inner walls, discharge from the steam vent of housing upper end then, good exhaust effect, when the rainy day, rainwater drops on the drip tray through the steam vent of housing upper end, by drainpipe rainwater is discharged to the outside of housing then, thereby has avoided rainwater to enter exhaust duct or indoor, anti-rainwater is effective.

The utility model is described in further detail below in conjunction with drawings and Examples.

Description of drawings

Accompanying drawing 1 is the structural representation of rain-proof type exhaust apparatus among the utility model embodiment

Accompanying drawing 2 is the left view of accompanying drawing 1;

Accompanying drawing 3 is the vertical view of accompanying drawing 1;

Accompanying drawing 4 be in the accompanying drawing 1 A-A to view.

Among the figure: the 1-upper shell; The 11-steam vent; The 2-drip tray; The 21-osculum; The 3-drainpipe; The 4-lower house; The 41-connecting hole; The 5-blast pipe.

The specific embodiment

Embodiment: as accompanying drawing 1, accompanying drawing 2, shown in the accompanying drawing 3, the rain-proof type exhaust apparatus, comprise upper shell 1 and lower house 4, the top of upper shell 1 bottom and lower house 4 is fixed together, be communicated with between upper shell 1 and the lower house 4, the upper end of upper shell 1 is provided with steam vent 11, the bottom of lower house 41 is connected with the blast pipe 5 that is communicated with lower house 4, the cross section of upper shell 1 and lower house 4 is respectively rectangle, the longitudinal section of upper shell 1 is up-narrow and down-wide trapezoidal, the longitudinal section of lower house 4 is wide at the top and narrow at the bottom trapezoidal, be provided with drip tray 2 in the upper shell 1, drip tray 2 be shaped as circle, the longitudinal section of drip tray 2 is wide at the top and narrow at the bottom trapezoidal, the area of the projection of steam vent 11 on drip tray 2 bottoms is less than the area of drip tray 2 bottoms, drip tray 2 is provided with four osculums 21, and lower house 4 is provided with four connecting holes 41, is provided with four drainpipes 3 between drip tray 2 bottoms and the housing, drainpipe 3 one ends are connected with osculum 21, and the other end is connected with connecting hole 41.

As shown in Figure 4, the tangent connection of inwall of the excircle of the upper end open of drip tray 2 and four faces of upper shell 1, prevent drip tray 2 rocking in the horizontal direction, have the gap between the inwall of upper shell 1 and the drip tray 2.

Upper shell 1, lower house 4 and drip tray 2 also can be other shapes, needing only between drip tray 2 and the upper shell 1 or having the gap between the lower house 4 to allow gas pass through, rainwater can be discharged to the outside of upper shell 1 and lower house 4 by drip tray 2, can prevent that rainwater from entering exhaust duct or indoor getting final product.

During use, be connected with constructure ventilation mouth or exhaust duct by tube connector 5, owing to be provided with drip tray 2 in upper shell 1 and the lower house 4, has the gap between drip tray 2 and upper shell 1 inwall, so, the gas that enters from blast pipe 5 can pass through from the gap between drip tray 2 and upper shell 1 inwall, discharge from steam vent 11 then, good exhaust effect, when the rainy day, rainwater drops on the drip tray 2 through steam vent 11, by drainpipe 3 rainwater is discharged to the outside of upper shell 1 and lower house 4 then, thereby avoided rainwater to enter exhaust duct or indoor, anti-rainwater is effective.
