Abstract

A downwind cap is to solve the problem that air exhausting of an air exhaust pipeline is blocked under a natural state. The 'stinking' phenomenon of a sewer in a building is a technical difficulty which cannot be solved for a long time; as the air exhaust pipe led to the roof often generates a down draft phenomenon due to the change of the air direction, and down draft blocks air exhausting, 'stinking' pollutes indoor air. Under the condition of natural ventilation, the downwind cap can guide the natural wind into a technology with the air drafting capacity and is mounted at an outlet of the air exhaust pipeline without consuming any energy; furthermore, at any wind direction, the air exhaust pipeline can generate the air drafting capacity; the natural wind is stronger, the generated air drafting capacity is higher. By the downwind cap technology, the down draft phenomenon is avoided, and indoor air is refreshing. The downwind cap is ingenious in idea, simple in structure, low in cost and convenient to mount, and the blank of an air exhaust technology is filled. Besides the building industry, the downwind cap is also suitable for spaces, such as ship cabins and food processing, which exhaust air by natural wind and is wide in market prospect.

Description

Cap with the wind

1, technical field cap core technology with the wind: under natural state, do not consume any energy consumption, uncontrolled natural wind can be guided into the negative pressure energy that can form certain numerical value at exhaust duct road junction place to, wind speed, negative pressure makes exhaust duct no longer down draught, make the dirty gas Accelerating Removal of exhaust duct, thoroughly do away with " anti-taste " phenomenon of sewer pipe, maintained room air pure and fresh, benefit huge numbers of families.

2, background technology build a building in exhaust duct, usually produce " anti-taste " phenomenon because of down draught, pollute indoor air environment.Trace it to its cause, all because nature wind direction, wind-force often change, existing anti-storm design " venetian blind type, funnel-shaped " etc., all can not prevent the down draught phenomenon produced because the change of wind direction wind-force.

3, summary of the invention with the wind cap technology be exactly at existing exhaust duct road junction place, install a set of cap with the wind additional, when natural wind passes through the ventilating duct of cap with the wind, under the effect of physical surface, speed is constantly accelerated, and when arriving exhaust duct road junction, wind speed reaches maximum, define the negative pressure region of certain numerical value at exhaust outlet place, negative pressure has thoroughly done away with " anti-taste " phenomenon of sewer pipe.Because the design of cap does not with the wind have directionality, therefore the wind-force in any direction all can not produce down draught phenomenon.

4, detailed description of the invention with the wind cap be skillfully constructed, structure is simple, with low cost, easy for installation.Cap technology solves sewer " anti-taste " this technical barrier with the wind, fill up a technological gap, and the market prospects of cap technology are with the wind very good, but this good thing being conducive to huge numbers of families to be run well, standard is made by standardization room, Architecture Design Institute, will make the design of installing cap with the wind when designing, this part good thing will be done satisfactorily.

Claims

1. cap core technology with the wind: under natural state, do not consume any energy, uncontrolled natural wind can be guided into the energy that can form certain numerical value negative pressure at exhaust duct road junction place to, wind speed, negative pressure makes exhaust duct no longer down draught, make the dirty gas Accelerating Removal of exhaust duct, thoroughly do away with " anti-taste " phenomenon of sewer pipe, maintained room air pure and fresh, benefit huge numbers of families.

2. the technical characteristic of cap with the wind: the ventilating duct be made up of upper and lower two hemisphere, when natural airflow is through ventilating duct and when arriving exhaust outlet place, wind speed is constantly accelerated and is reached maximum, the ventilating duct of cap is designed to the effect that sphere, cone face, inclined-plane, curve dignity etc. all can reach nature quickening wind speed with the wind, is all the utilization of cap technology with the wind.

3. cap technical characteristic with the wind: natural wind is when running into choke shoulder through ventilating duct, wind direction can slightly upwards, and this is conducive to expanding negative pressure region at exhaust outlet place, impels dirty gas to discharge more smoothly, the choke that shape and size change to some extent is takeed on and is designed, and is all the utilization of cap technology with the wind.

4. cap technical characteristic with the wind: when cap adopts PVC material with the wind, for ensureing the intensity of cap with the wind, can reserve in through hole at four root posts connecting upper and lower hemispheres, insert reinforcing rod, this way inserting reinforcing bar in PVC material is the utilization of cap technology with the wind.

5., because exhaust duct bore is different, therefore the cap with the wind coordinated with it also size can have respective change, as long as its principle meets the core technology of cap with the wind, is all the utilization of cap technology with the wind.

6. the connection at cap and exhaust duct road junction place with the wind, with glueing joint, can mechanically can connect, and mechanically can connect with after splicing, no matter connecting by that method, as long as meet the core technology of cap with the wind, is all the utilization of cap technology with the wind again.

7. the production method of cap can be varied with the wind, can produce with 3D printer, can produce with injection machine, also available metal processing method is produced, can integral production, also can be divided into several assembling parts and form, its size also can change to some extent, as long as its principle meets the core technology of cap with the wind, it is all the utilization of cap technology with the wind.

8. the material of cap can be varied with the wind, both can be metal material, can be plastic material, also can be composite etc., no matter is which kind of manufacture of materials, as long as meet the technical characteristic of cap with the wind, is all the utilization of cap technology with the wind.

9. cap technology guides paired indoor to have the technology of exhausting ability outdoor natural wind with the wind, and except building industry, boats and ships bin, toilet, food-processing industry also has wide purposes, as long as meet cap technical characteristic with the wind, is all the utilization of cap technology with the wind.
