The unpowered blast cap of a kind of air exhaust passage
Technical field
The present invention relates to a kind of unpowered blast cap of air exhaust passage of high residential building.
Background technology
Unpowered blast cap utilizes natural natural wind speed to promote the turbine rotation of blower fan and the principle of indoor-outdoor air convection current, the air of any parallel direction is flowed, accelerate and change from bottom to top vertical air flowing into, to improve a kind of device of room ventilation ventilation effect, its not electricity consumption, noiselessness, can operate for a long time, get rid of indoor hot gas, moisture and oxious gas, it is according to air natural rule and air-flow flow principles, and rational design is at the top of roofing, hot gas in the rapid discharge chamber of energy and dirty gas, improve indoor environment.
The conventional unpowered blast cap being located at air exhaust passage top, due to by outdoor distinguished and admirable impact, it is sometimes not ideal to pull out wind effect, and the smell of indoor toilets can not fully be discharged.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of unpowered blast cap of air exhaust passage of high residential building, and its structure is simple, and it is better to pull out wind effect.
In order to solve the problems of the technologies described above, the invention provides a kind of unpowered blast cap of air exhaust passage of high residential building, it comprises: be located at air exhaust passage top, in hollow transparent channel, be located at the unpowered blast cap in this transparent channel top port; Transparent channel bottom port is arranged in the top ports of air exhaust passage; Transparent channel comprises hollow, the symmetrical up and down and frustum be integrally formed, and the top port of upper frustum is the top port of described transparent channel, and the bottom port of lower frustum is the bottom port of described transparent channel.
Be respectively equipped with annular spray pipe in the top exterior walls of transparent channel, on the inwall of middle part, this annular spray pipe is distributed with hole for water spraying; When the inside and outside wall of transparent channel is dirty, connect the outer wall that water source can wash away transparent channel.
Described air exhaust passage, transparent channel and unpowered blast cap are coaxially set, and are beneficial to raising and pull out wind effect.
The below of described transparent channel is provided with for by the snoot in solar ray collecting to described transparent channel, increases the light entering transparent channel further.
Described hollow frustum is the frustum of a cone, is beneficial to uniform stream and enters unpowered blast cap; Also can be polygon frustum, such as quadrangle, pentagon or hexagon frustum.
Relative to prior art, the technique effect that the present invention has is: the unpowered blast cap of air exhaust passage of high residential building of the present invention, on the unpowered blast cap basis of routine, increase by one in hollow transparent channel, sunlight directly can be injected transparent channel from the inclined-plane of the upper frustum of transparent channel to add hot-air, hot-air has the characteristic of rising, makes to pull out wind scorpion more remarkable; The sidewall of described lower frustum is relative with roofing, the heat radiation of roofing can be entered described transparent channel from the sidewall of described lower frustum, and then be beneficial to the air in heating transparent passage further.
Accompanying drawing explanation
In order to clearly demonstrate innovative principle of the present invention and the technical advantage compared to existing product thereof, by applying the limiting examples of described principle, two possible embodiments are described by means of accompanying drawing below.In the drawings:
Fig. 1 is the longitudinal profile structural representation of air exhaust passage with unpowered blast cap of high residential building of the present invention.
Detailed description of the invention
As Fig. 1, the air exhaust passage of the high residential building of the present embodiment comprises with unpowered blast cap: be located at air exhaust passage 1 top, in hollow transparent channel 3 (preferred glass or transparent plastic are made), be located at the unpowered blast cap 2 of this transparent channel 3 upper end.Transparent channel 3 comprises hollow, laterally zygomorphic upper frustum 31 and lower frustum 32.Air in this product utilization solar energy heating transparent channel 3, hot-air rises, and increases and pulls out wind scorpion.Wherein, sunlight directly can be injected to add hot-air transparent channel from the inclined-plane of transparent channel, and the surrounding inclined-plane of transparent channel 3 random time can absorb light by day.Air exhaust passage 1, transparent channel 3 and unpowered blast cap 2 are coaxially set.
Be respectively equipped with the annular spray pipe 8 for connecting running water pipe in the top exterior walls of transparent channel 3, on the inwall of middle part, this annular spray pipe 8 is distributed with hole for water spraying; When the inside and outside wall of transparent channel is dirty, connects the inside and outside wall that water source can wash away transparent channel 3, guarantee that extraneous light, heat radiation enter transparent channel 3 smoothly, avoid greasy dirt to block.
Described transparent channel 3 is the frustum of a cone, is beneficial to uniform stream and enters unpowered blast cap 2.
The shape of cross section of described transparent channel 3 cross section and described air exhaust passage 1, in the same size, be beneficial to smooth in exhaust, make uniform stream enter unpowered blast cap 2.
Described transparent channel 3 can also be oval frustum (namely cross section is for oval), or polygon frustum (advantageous cross sections is quadrangle, pentagon, hexagon, heptagon or octagonal frustum), be beneficial to multi-angle and absorb sunlight, the sidewall of described lower frustum 32 is relative with the roofing 7 of high residential building, the heat radiation of roofing 7 can be entered described transparent channel 3 from the sidewall of described lower frustum 32, and then be beneficial to the air in heating transparent passage 3 further.
