Below in conjunction with drawings and Examples the present invention is further described.

In order to illustrate the basic principle of house respirator, existing a series of discoveries with physical vacuum scholar Huo Busen are expressed as follows.

Fig. 1 is that Huo Busen (Hobson) finds Hobson effect experiment device schematic diagram.Huo Busen has delivered six pieces of papers respectively at J.Vac.Sci.and Technol. and Brit.J.Appl.Phys. at the beginning of ten generations of the seventies to eight, introduced his a series of discoveries.According to gloomy 1973 discovery of cloth suddenly: under the certain condition, be connected with the porous plug situation of two Room of the thermal transpiration phenomenon that two Room that are connected with the passage of rough inner surface are taken place is the same, i.e. circulation make whole big system to $\mathrm{P\; a}\sqrt{\mathrm{T\; a}}\mathrm{=\; P\; b}\sqrt{\mathrm{T\; b}}$ The equilibrium state transition because molecular density ρ is relevant to the molecular number n=(N/Ro of unit volume) P/T.Therefore the relation of pressure and system's two ends temperature can be expressed as Pa/Pb=(Ta/Tb) ^1/2In the Huo Busen work afterwards, study the situation that the smooth passage connects two Room, experimental results show that the Pa/Pb=α (Ta/Tb) of the equilibrium state of two Room ^1/2, and confirm α value under design conditions between 1.1～1.3, and relevant with the temperature difference.Huo Busen is in the cold junction that temperature is Ta to a chamber and c chamber in the device of Fig. 1, the b chamber is in the hot junction that temperature is Tb, communicates by rough channel between a chamber and the b chamber, joins by the smooth passage between b chamber and the c chamber.Have according to equation of equilibrium state: Pa/Pb=(Ta/Tb) ^1/2, Pb/Pc=α (Tb/Tc) ^1/2, in the formula, Ta=Tc, so the pressure in a chamber and c chamber is than being Pc/Pa=α.Because Tb＞Ta, factor alpha＞1 produces pressure difference Pc-Pa between a chamber and c chamber.Huo Busen is also 28 grades of this device serial connections, and having obtained utilizing the temperature difference to produce pressure ratio is 23.3 air extractor.In his a series of activities explanation smooth passage under certain condition, the probability by rough channel is big in the other direction than it from the hot junction to the cold junction for the molecule total pressure.This research work and boundary condition thereof are for producing the total pressure flow and having important theory to be worth to similar air exchange technology among the present invention.

The present invention is transformed into the new structure that smooth passage and rough channel are nested together to the device of Huo Busen effect, as shown in Figure 2.It has produced new result of use, produces at indoor/outdoor temperature-difference under the effect of pressure reduction, and indoor muddy air is discharged outdoor by the smooth passage, and outdoor fresh air flows into indoor by rough channel.Inner core 2 of the present invention is divided into rough channel and smooth passage to passage, the smooth passage is discharged indoor muddy hot-air outdoor, the barrel of inner core 2 is passed to heat the outdoor colder fresh air (heat dissipation technology can make this portion of hot exchange rate reach about 48% usually) that sucks by rough channel, the temperature of fresh air in the inlet chamber is increased, reach the purpose of first step heat exchange.

Fig. 3 is anti-cone of house respirator and jam structural representation.Inner core 2 has the convex surface can be towards indoor anti-cone 3 in an indoor termination.Be connected to jam 4 on the anti-cone 3.Anti-cone 3 and jam 4 can move vertically.During work, anti-cone 3 forms opening with the oral area of urceolus 1, and jam 4 forms the gap with the oral area of inner core 2.Gap and opening can be adjusted the opening amount by the axial location of adjusting anti-cone 3 and jam 4.Anti-cone 3 separates the fresh air from the rough channel suction with the muddy air of discharging from inner core 2, inhaled air is obtained anti-cone 3 indoor temperature of living in by anti-cone 3 reflections simultaneously, to diffusion all around, can not form the cold wind in the inlet chamber.Because the opening amount that can regulate internal and external channel by the axial location of regulating anti-cone 3 and jam 4 can be regulated ventilation in actual use as required, also can close inlet and outlet in case of necessity.

The present invention can be outside inner core 2 buildings the bend pipe 6 of a band of termination weather shield 5, as shown in Figure 4.The design of bend pipe 6 provides three kinds of functions, and it can be separated the input and output gas of an outdoor end, reduces and discharges outdoor muddy gas and be inhaled into mixing of indoor fresh air; The structure of bend pipe 6 has been for the heat content balance of whole cavity provides condition, and pipe is long and influence product appearance design in not causing, and causes exhaust to pour in down a chimney in the time of can avoiding big blast; Certainly also, anti-rainwater provides supporter for pouring into.

House respirator of the present invention as shown in Figure 3 and Figure 4.It is made up of urceolus 1, inner core 2, anti-cone 3, jam 4, weather shield 5 and bend pipe 6 etc.The house respirator that it is made up of the indoor and outdoor passage that communicates.The invention is characterized in that passage is made up of urceolus 1 and inner core 2 inside and outside two-layer tube-in-tube structures, its tube-in-tube structure forms the different passage of degree of roughness.Under general indoor and outdoor temperature condition, the passage of inner core 2 is a smooth surface, and the passage of urceolus 1 is a rough surface.Under given chamber internal and external temperature condition, the passage of inner core 2 is a rough surface, and the passage of urceolus 1 is a smooth surface.Inner core 2 is housed in the urceolus 1, inner core 2 is separated into inside and outside two passages to venting channels, urceolus 1 is longer than at the two ends of inner core 2, the termination of inner core 2 in building has an anti-cone 3, be connected to jam 4 on it, anti-cone 3 can move vertically with jam 4, and inner core 2 termination outside the building has the bend pipe 6 of a band weather shield 5.The inner surface of urceolus 1 is a rough surface.Inner core 2 is made by highly heat-conductive material.

Constituted whole basic structure of the present invention by Fig. 3 and Fig. 4 combination.It is an aspect of this respirator that the aforementioned Huo Busen of utilization effect forms indoor-outdoor air mobile, and the maintenance room air is fresh, and quite a few is to be finished by flooding mechanism in addition.So-called room air muddiness, actual breathing and other activity that is indoor owing to the people, oxygen partial pressure is lower than outdoor, and the dividing potential drop of carbon dioxide and other pernicious gas is higher than outdoor.Flooding mechanism is also naturally-occurring in solid and liquid, but the effect that can not show a candle in gas is obvious.Indoor and outdoor often is in conducting state, makes indoorly to keep fresh very effectively.The heat exchange of indoor-outdoor air composition also not only occurs in the surface of passage, and a large amount of gas molecule heat exchanges are finished in cavity lane.The present invention has studied the heat content state of different air compositions, carbon dioxide and other muddy gas mostly are three atoms and polyatomic molecule, under identical temperature, the free degree of each molecule and enthalpy amount are greater than diatomic molecule oxygen, more greater than the ionization negative oxygen ion.Molecular collision has effectively improved the interior energy of fresh oxygen molecule, under certain boundary condition, makes the interior fresh air of inlet chamber near room temperature.Also find by experiment: the gas that molecular weight is little is easy to the thermotropism end motion, and the gas that molecular weight is big is easy to move to cold junction.Because during the indoor and outdoor conducting, room temperature is subjected to externally temperature influence comparatively serious at cold district and seasonal variations, this discovery has the product in extensive market significant to design.

The embodiment of comprehensive various specification requirements test shows, indoor and outdoor two ends bore difference is because temperature in people's living environment, constantly changes and decision throughout the year with in one day.Usually, the careat of design inner core 2 is 1.1～1.3 to 1 with the ratio of outdoor area.The length-to-diameter of inner core 2 is 2.5～8.5 to 1.For being suitable for general environment condition needs, embodiment has used the method for stage casing awl tube, with the effect that guarantees that the four seasons all have good ventilation and protection room temperature not to be affected substantially.Use the way of stage casing awl tube and column casing, can also stop effectively in the outdoor dust inlet chamber, the work of respirator is not subjected to the influence of extraneous adverse circumstances.
