Abstract
A smoke warning device has a warning insert (1) which can be fixed in a base and is provided with an optic module which comprises a light source (6), a light receiver (7), a measurement chamber(8), a central diaphragm (10), a bottom (11) and a labyrinth system with diaphragms (9) arranged at the periphery of the measurement chamber. The bottom (11) is designed in such a way that its centre is located further away than its edge from a plane determined by the light source (6) and light receiver (7). The bottom (11) is preferably funnel-shaped with the shape of a cone or pyramid. The dust particles which deposit on the bottom are thus substantially further away from the actual measurement zone, substantially reducing the probability of light scattered by the dust particles reaching the measurement zone.
Description
The present invention relates to a kind of smoke alarm, it has a probe unit that can be fixed in base, one contains a light source, an optical receiver, between a measurement, a central stop, at the bottom of one, and the optical module of a tortuous sealing system, the sealing system contains some diaphragms, they be distributed between measurement around.
This smoke alarm is commonly referred to as astigmatic smoke alarm, and except that containing optical module, it also selectively contains is with a kind of sensor, as temperature sensor, as everyone knows, when designing the optical module of this smoke alarm, outside interference light can not penetrate that smog then is easy to penetrate between measurement.When design light source and optical receiver, the light of light source can not directly arrive receiver.Because smoke particle enters session, source light carries out scattering by these rocks, and wherein just some scattered light arrives receiver, thereby evokes an electric signal.
Obviously, for avoiding wrong report, strengthen the reliability of the astigmatic smoke alarm of this kind, the main light that still will guarantee to have only smoke particle could scattering light source to send, like this, except smoke particle, other particle just can not enter between measurement, answer the implication of other this speech of particle of interpreted in its broadest sense, ie, for example, its meaning just includes insect.People recognize the insect problem for some time, and this problem is solved by the bug deflector around between measuring.
Can learn a kind of astigmatic smoke alarm by DE-A-4412212, it comprises that between the box-like measurement of circle, the front side of circle box is fixed on the plate between this measurement, and this plate then links with the ceiling in monitored room, and its sidewall is a bug deflector.Between measuring anterior leave above-mentioned plate and in the face of the place of detector dome be stamped one flat.
Its practice utilization of astigmatic smoke alarm that this kind has between smooth cylindricality measurement shows, the service time of this detector is long more, and its wrong report frequency is high more, and its main cause is, the light of light source has carried out scattering by the grit that is deposited between measurement, and just looking like has smoke particle to exist equally.For getting rid of this wrong report, to have to remove dust, this just means and brings unnecessary ancillary cost.
Purpose of the present invention just provides a kind of previously described smoke alarm, wherein, can be avoided fully by the wrong report that the grit scattered light brings, or reduce as far as possible largely, therefore can obtain a very long maintenance cycle.
According to the present invention, this purpose is achieved by following method, and design is during the end, and its center is far away than the plane of its Edge Distance light source and optical receiver composition.
The method according to this invention can lower the interference effect of grit greatly, and reason is that the sort of of this grit interference ratio past wants much far away from measured zone, and thus, the possibility that the grit scattered beam arrives between measuring has just reduced many.
We know, intersect the central area of the optical axis of light source and optical receiver between measuring, just at the middle position at the end.Because on this position or perhaps the summit of the tapered region at the end, its range observation face farthest, and dust mainly is this position that is deposited on the end, so the light that light source sends never can arrive and be deposited on the grit at the bottom of the conical surface and be scattered back between measurement.
It is characterized in that according to first kind of preferred embodiment of smoke alarm of the present invention the end is bucket-shaped and shape is the conical surface or pyramid sample.
In second kind of preferred embodiment of smoke alarm of the present invention, the end is a kind ofly to sieve shape or netted structure, and as a kind of bug deflector.This embodiment advantage is, the more previously described the sort of few a kind of element of smoke alarm, and this has just correspondingly had the advantage on the cost.
It is characterized in that according to the third preferred embodiment of smoke alarm of the present invention, the inside surface at the end is having many thin slices that extend upwardly on the direction between measuring, by layout, quantity, height and the phase mutual edge distance of selecting them, make the light that drops on before arriving this end, just drop on the thin slice, and optical receiver see that all parts at the end all are thin slice at the end.
According to the present invention,, reduced again by the possibility that is deposited on the grit scattering bright dipping at the end between measurement by vertically upward thin slice at the design end.This is because grit is not to be deposited on the thin slice, but is deposited on the bottom of end inside surface, should then can be blocked from the light between measuring by thin slice in the zone.In addition, thin slice also can like this, just improve the measurement reliability of smoke alarm greatly as a kind of screen to block the light of external light source according to invention.
Owing to absorbed the unnecessary light that rescattering or reflection cause, promptly be called the light of bias light, so just bring another important advantage, promptly the tolerance of product can reduce.That is to say that improved owing to absorb the ability of bias light, the position accuracy demand of light source and optical receiver just can reduce.
According to following embodiment and accompanying drawing, the elaboration that the present invention can be detailed, wherein:
Accompanying drawing 2 is the figure that cuts open of II-II along the line in the accompanying drawing 1, and ratio is little than accompanying drawing 1.
Shown astigmatic smoke alarm includes probe unit 1 usually, it can be fixed in (not expression among the figure) on the base, base then preferably is loaded on the room ceiling that needs monitoring, also include detector cover plate 2, cover plate 2 covers on the probe unit 1, when detector was in running order, the conical surface of cover plate can provide smog slit entrance 3, allowed it directly facing to monitored room.Probe unit 1 includes a box-like matrix substantially, face one side of surveying the conical surface at it and be furnished with an optical module 5, assembly 5 is surrounded by sidewall 4, one side at its printed circuit board (PCB) (not showing among the figure) that is provided with a band analytical electron equipment facing to the detector base.This panel detector structure is all very familiar, does not remake detailed annotation at this.About this point, can be referring to AlgoRex series detector (AlgoRex-Cerberus AG registered trademark), also can be referring to european patent application No.95117405.1 etc.
If monitored room has produced smog,, pass smog slit entrance 3 along continuous straight runs then and flow to the bucket-shaped end 11 just it rises to smoke alarm.The ends 11 structure is furnished with star fin 12 for sieve shape or netted, its outside, and smog is directed at the end 11 through these fins.Like this, between smog has just vertically flowed into and has measured 8 and fringe area.The end 11 reason of doing bucket-shaped design be make between its range observation far away, if the end is flat, just near between measurement.Penetrate between measurement 8 grit can scattering from the light of light source 6, act on equally with smoke particle, they are deposited on the conical surface at the end 11, and are positioned at outside the luminous incidence zone of light source 6, so the interference effect of smoke particle just greatly reduces.
By accompanying drawing as can be seen, the bucket-shaped regional shape at the end 11 such as pyramid or a pyramid of cutting the top, preamble are mentioned, all are sieve shape or reticulate texture on pyramidal each side plane.For ease of distinct, accompanying drawing 1 reticulate texture on this kind pyramid plane that schematically drawn.Preferably, fin 12 is positioned at the outside at the end 11, and is distributed in pyramidal side edge.
Through to the particular design at the end 11, can reduce greatly along the interference effect of being amassed the end of in 11 grit.Reason is, the inside surface at the end 11 has many thin slices 14,15, look by projection, they are vertically upward, thus, by layout, quantity, height and the phase mutual edge distance of selecting them, just can be so that before arriving the end 11, drop on the thin slice by 11 light at the bottom of the directive between measuring, and also optical receiver 7 can only be seen the thin slice 14,15 at the end 11.Therefore,, dust can not be attached on the vertical wall of thin slice, so that the danger of grit scattered light has just reduced is many because being easier to be retained at the end.Except can stop the end 11 measured between 8 the irradiate light, thin slice 14,15 can also stop that optical receiver 7 avoids the irradiation of exterior light.
As shown in the figure, not every pyramid face all has thin slice, that pyramid face that has only relative with light source 6 and optical receiver 7 two pyramid faces and their to surround just has.Pyramid facing to light source 6 and optical receiver 7 has been worn thin slice 14 longitudinally, these thin slices are parallel with the pyramid base, the side of being enclosed by above-mentioned two pyramid bread has a thin slice 14 longitudinally at least, and some horizontal thin slices 15 are arranged, they and vertical thin slice 14 quadratures.Vertically the optical axis of the optical axis of thin slice 14 and its relative light source and relative optical receiver is quadrature roughly at least.The fundamental purpose of transverse slice 15 is to provide the optics decoupling for light source 6 and optical receiver 7.
The end 11 and whole probe unit 1 the same (except that light source 6 and optical receiver), form by a kind of suitable plastic, can be used as a kind of injection molding parts produces, some locking members (not drawing among the figure) are arranged on its limit, the sidewall 4 of the end 11 with optics assembly 5 can be linked together, and can demolition (seeing accompanying drawing 2).
In order to absorb bias light better, optical module 5 at least some parts, particularly Si Zhou diaphragm 9, central stop 10 and be glossiness facing to 8 cover plate between the measurement at the end 11, that is to say that they are reflecting surface rather than habitual now mat surface.Obviously, the whole inside of other parts or optical module 5 also all has the surface of a gloss.
Preamble is imagined, and bias light preferably can be absorbed and be destroyed by mat surface, but this imagination has but been ignored light and still can be entered between measurement inevitably after by the scattering process of mat surface.Other direction, if adopted glossy surface, they just can play black mirror effect, reflex to nonabsorbable light an appointment and direction that do not have interference effect on, for example reflex to adjacent around on the diaphragm.Because reflecting surface is black, therefore only reflect about 5% incident light, through the repeated reflection of these reflectings surface, incident light can almost completely be destroyed.Glossy surface can obtain by the mode of injecting molding, in each surface of mould, is thought of as at least to that surface of glassy surface and will adopts a kind of comparatively suitable surface, preferably can adopt polished surface.
Improve another epochmaking being characterised in that of the measurement reliability of above-mentioned smoke alarm, diaphragm 9 or great majority wherein are not the rotation symmetrical distribution all around, but on these diaphragms, light source 6 sends the incident angle of light beam and incident angle that optical receiver 7 is received light beam all is a constant.Diaphragm 9 is rotation and is symmetrically distributed and is meant that diaphragm arranges with respect to the center rotation all around.In accompanying drawing 1, be not symmetrically distributed with just not being rotation near diaphragm around four of optical receivers 7 near diaphragm around four of light source 69.Select incident angle, make incident light and unabsorbed light reflect between diaphragm as much as possible all around.
As shown in the figure, each diaphragm 9 all around is made up of two planes at an angle to each other approximately, so, select their inclination angle and the distance and the length thereof of 9 of diaphragms all around, make be mapped to around the light of diaphragm 9 can not directly arrive the inside surface of sidewall 4.But diaphragm 9 and reflex on the adjacent diaphragm around can both arriving by a diaphragm, and, this non-rotating symmetrical structure that most of diaphragms 9 all around form can absorb bias light better, thus, position and components accuracy for light source 6 and optical receiver 7 require also can reduce, so just form the low detector of a kind of fault sensitivity.
By accompanying drawing 1 as can be seen, diaphragm 9 is done sharplyer at the interior end facing to central stop 10 as far as possible all around.The advantage of this way is, has only light seldom to fall on this tip, and the light that reflects everywhere just seldom.
In the production run of ablation injection molding, because the lead that adopts has certain thickness, thus sharp degree is limited to some extent, and this restriction can not be satisfied the inner sharp degree requirement of diaphragm 9 all around.The inner of detector cells 1 can reach desirable sharp degree requirement by following method, inserts the magnetic core (profile of tooth or Z-shaped) of better shape in injection molding, to generate above-mentioned the inner.Thin being pickled with grains or in wine with diaphragm 9 around forming is housed in injection molding, and is furnished with the classification magnetic core of above-mentioned shape in carefully poor, the magnetic core classification will carefully be pickled with grains or in wine and middle heart block.Therefore, between the thin poor and classification magnetic core of injection molding, can generate each tip.
Practical test shows, use simultaneously pointed the inner around diaphragm and optical module parts (diaphragm 9 all around, central stop 10,8 cover plate between measurement) can obviously reduce basic pulse, and detector can reduce the susceptibility of sharp dust and condensation product.
By also finding out in the accompanying drawing, light source 6 and optical receiver 7 lay respectively within chest 16 and 17.Two chests 16 and 17 are contained in covering of measuring chamber 8, are open to the bottom, and its open side was sealed by the end 11.In its front side facing to central stop 10, chest 16 and 17 is closed by a fan window, and an export and import is arranged respectively.These windows are different with the case window of the astigmatic smoke alarm of now knowing, they are independent parts.
Know that now the window of astigmatic smoke alarm is made up of two parts, wherein a part is contained on the cover plate between measurement, and another part then is contained at the end.When loading onto the end, serve problem through regular meeting by mounting strap, between the two halves of window, can form one light slit, disturb thereby give to send light and receive light belt.A case window just can be eliminated this interference, and the position precision between the two halves of window can not cause this class problem.
As shown in Figure 2, between window 18 its first half of chest 16 and the latter half a skew is arranged, form is as two scissors.Therefore, the injection molding of design need not same template, and like this, the skew two halves that have of light import and outlet can adopt separately molded element, so these windows can obtain accurate design shape and bright and clean surface.
