Description
Technical field
The present invention relates to sense cigarette apparatus fields, and in particular to vertical layout osmosis type kitchen special photoelectric smoke detector.
Background technique
Photoelectric smoke device is the concentration that cigarette is measured by the inductor of light beam and a light, when which designs, light
Beam is to deviate optical inductor, and after smog enters induction room, smog ion can scatter to segment beam on optical inductor,
When smokescope increases, just has more light beams and be dispersed on optical inductor, when sensing enough light beams, just
It can alert.
The layout of existing photoelectric smoke device is therefore emission lamp, sense by emission lamp, photosensitive head while layout on chassis
Shaven head is close apart from chassis surface, usually allows cigarette to gather using some special structural textures, then utilizes scattering conversion light
Angular illumination to photosensitive head on, in the prior art, research emphasis usually is to solve the design of optical path and prevent common
The attachment of dust, to promote the precision for solving detection.
But in the prior art, kitchen place is the mostly important position that photoelectric smoke device is laid, usually light herein
Inductance cigarette device and natural gas main valve link, i.e., when photoelectric smoke device experiences heavy smog, control immediately to natural gas
Device issues alarm signal, and natural gas control device can then cut off main valve immediately.Since photoelectric smoke device usually has delay function,
That is photoelectric smoke device can't alarm immediately when sensing dense smoke, but need whether Time delay measurement has lasting dense smoke, only
It just will call the police when having lasting dense smoke, to achieve the purpose that avoid wrong report.It is usually needed in the life of the family in Southwestern China area
Heavy oil carries out quick-fried to food, and after to oil heating, by the moment of food contact high temperature oil, this usually will cause of short duration dense smoke
It generates, and since photoelectric smoke device usually has delay function, this kind of phenomenon tends not to cause false alarm, but we observe
It was found that with the increase for using the time, even if the photoelectric smoke device for having delay function usually can issue alarm signal, therefore,
We have found that a kind of special phenomenon, i.e., the photoelectric smoke device newly installed not will cause alarm generating moment smog, but with
Time integral, the oil smoke of same cooking manufacture often will cause alarm, and appearance of once alarming can then cut off gas supply immediately
Valve, this often results in cooking interruption, and this wrong report phenomenon often appears in the photoelectric smoke device using 2 years or more.
Summary of the invention
The present invention can solve after optical detector of fire smoke works normally for a long time in kitchen in high oil smoke life family, reduce
The probability of false alarm, to provide a kind of vertical layout osmosis type kitchen special photoelectric smoke detector.
The present invention is achieved through the following technical solutions:

The interior collection cigarette set small-caliber end end of face is provided with device aperture, is equipped with emission lamp in the device aperture, the device where emission lamp
The central region of the interior collection cigarette set of the underface in part hole is provided with another device aperture, is equipped with photosensitive head in the device aperture；
The small-caliber end of outer exhaust fume collecting hood is socketed in the large diameter end of interior collection cigarette set in a manner of zero clearance, the interior collection cigarette
It puts on and is provided with outage, which is located at interior one end for integrating cigarette set inner wall as inner end, which is located at interior collection cigarette set outer wall
One end be outer end, inner end be directed toward outer end direction be in the diagonally downward direction；
The interior collection cigarette set inner wall is provided with side wall permeable formation, and the side wall permeable formation includes being attached to interior collection cigarette set inner wall
Cotton net in length and breadth, the super-hydrophobic super-oleophylic layer adjacent with cotton net in length and breadth, zero degree of sizing adjacent with super-hydrophobic super-oleophylic layer
Paper layer；The outage is built-in with guidance cotton thread and overlaps with cotton net in length and breadth, and the cotton net in length and breadth is by lateral cotton
Line and longitudinal cotton thread are cross-woven in length and breadth, and the super-hydrophobic super-oleophylic layer is by wood powder, nano zine oxide, stearic acid, nothing
Plate structure made of die casting is carried out with powder obtained by polystyrene and tetrahydrofuran combination drying again after water-ethanol combination drying,
Its thickness is directed toward large diameter end direction along interior collection cigarette set small-caliber end and is gradually reduced.
Design principle of the invention is as follows: in order to solve this wrong report phenomenon presented in background technique, we will make
Post analysis discovery is disassembled with the optical detector of fire smoke for being limited to 2 years or more year, since this kind of optical detector of fire smoke is located at kitchen,
The oil smoke that usually quick-fried generates can enter interior collection cigarette set, and due to the not persistently generation of oil smoke, within general 2 years
Optical detector of fire smoke is difficult alarm phenomenon occur when facing this kind of oil smoke, but as time increases, part oil smoke can be special
On the cigarette of collection inside set inner wall not easy to attach, as time increases, part dust will mix oil smoke and be attached to interior collection cigarette set
On inner wall, and protrusion is frequently formed, this phenomenon can make the light of reflection enter on photosensitive head, therefore, with the increasing of time
Add, grease attachment point increases, and this reflex was originally more, and the light for causing photosensitive head to be experienced is more and more stronger, also more next
Therefore photosensitive head can be made to reach preset limit value immediately generating low concentration cooking oil smoke closer to preset limit value, thus
The case where this false alarm, is also more and more.In order to solve this problem, that is, it needs to solve to enter attachment in interior collection cigarette set in oil smoke
After its inner wall, so that grease not stop for a long time in its inner wall, the mixing probability of grease and common dust is reduced, is subtracted with this
Few quantity that the protrusion that grease dust is mixed to form is formed in inner wall, finally reduces the initial photosensitive value of photosensitive head, and above-mentioned
The initial photosensitive value of photosensitive head is higher in phenomenon, very close threshold value.The application in order to achieve the above object, using collecting cigarette inside
Put on and begin to rehearse oilhole to solve, and be provided with the outage by it is a kind of it is inclined in a manner of be arranged, be obliquely installed mode according to above-mentioned,
It is outer that interior collection cigarette set can be flowed to after its oil attachment with in-line arrangement oilhole, it is in the conventional technology, interior without collecting cigarette set inner wall attachment inside
Although collecting cigarette set to be located in outer exhaust fume collecting hood, the small-caliber end of outer exhaust fume collecting hood will be far longer than the large diameter end of interior collection cigarette set, that is,
There is at least spacing of 10cm or so, this construction meeting between small-caliber end apart from outer exhaust fume collecting hood in the large diameter end of interior collection cigarette set
So that in the gap that part oil smoke both enters, and the present invention directly expands in collection cigarette set large diameter end make its size and
The small-caliber end of outer exhaust fume collecting hood is consistent, and the two forms zero clearance cooperation, therefore the two can directly be formed for storing above-mentioned row
The grease of oilhole, simultaneously as the bore of interior collection cigarette set is expanded, therefore more oil smoke will enter in interior collection cigarette set,
Therefore the attachment number of grease on interior collection cigarette set inner wall has been aggravated, so that scattered fat particles are easier to collect, then into
Outage is played instead by the purpose of more grease discharges.In the present invention, wherein outage uses capillary, research hair
Existing, general cooking generates 3 quasi-grease particulate matters, one kind be 10um can deposited fat particle, one kind is inhaling for 0.01-10um
Enter fat particles, one kind is gas molecule group, and in the moment that food is contacted with high temperature oil, or generating largely can deposited fat
Particle and inhalable fat particles, and can deposited fat particle and inhalable fat particles rise into light inductance with hot gas
Smoke detector, if using the scheme of outer exhaust fume collecting hood and interior collection cigarette set wide arc gap cooperation, largely can deposited fat particle will be into
Enter into the gap of the two, without entering in interior collection cigarette set, therefore the smaller inhalable fat particles of most particle diameters
Interior collection cigarette set can then be entered, under this design, it is interior collection cigarette set in attachment inhalable fat particles it is more, can deposited fat
Particle is less, and the self weight of inhalable fat particles is small, and mobility is very poor, therefore is difficult to be discharged after runner formation collects, and
Using the mounting means of zero clearance above-mentioned in the present invention, largely can deposited fat particle can also enter in interior collection cigarette set, with
Deposition increases, largely can deposited fat particle in the case where self weight with it is adjacent can deposited fat particle mix and also mix simultaneously
Short grained inhalable fat particles are closed, final confluence enters outage discharge.
Due to change it is interior collection cigarette set and outer exhaust fume collecting hood matching relationship so that largely can deposited fat particle also enter
Interior collection cigarette set can aggravate the dust concentration in interior collection cigarette set, therefore also have certain probability and cause to report by mistake in the case
Alert, in order to solve this problem, the present invention should devise acceleration and absorb and form the structure of infiltration to solve, so that entering Nei Ji
The hollow region that fat particles in cigarette set can permeate rapidly without being gathered in interior collection cigarette set for a long time, reduces oil smoke with this
Granule density reduces the generation of false alarm.Its structure is the side wall permeable formation that setting collects cigarette set inner wall inside, the side wall infiltration
Layer includes being attached to the interior collection cigarette set cotton net in length and breadth of inner wall, the super-hydrophobic super-oleophylic layer adjacent with cotton net in length and breadth and super thin
Zero adjacent degree of sizing paper layer of the super oleophilic layer of water；The outage is built-in with guidance cotton thread and overlaps with cotton net in length and breadth,
The cotton net in length and breadth is cross-woven in length and breadth by lateral cotton thread and longitudinal cotton thread, and the super-hydrophobic super-oleophylic layer is by wood
After powder, nano zine oxide, stearic acid, dehydrated alcohol combination drying again with powder obtained by polystyrene and tetrahydrofuran combination drying
Plate structure made of die casting is carried out, thickness is directed toward large diameter end direction along interior collection cigarette set small-caliber end and is gradually reduced.The knot
The design principle of structure is: due to not only being generated by a large amount of oil smoke in quick-fried food, can also generate a large amount of vapor, water steams at this time
Gas and oil smoke are mixed into optical detector of fire smoke, and the present invention carries out oil smoke and vapor using zero degree of sizing paper layer fast
Speed absorbs infiltration, and the cavity region for avoiding above-mentioned mixing smog extended stationary periods from collecting cigarette set inside causes false alarm, and after permeating
Grease and water adsorb grease when facing super-hydrophobic super-oleophylic layer, and water is isolated, and water is in zero degree of sizing
Is distributed in the form of natural evaporation in paper layer, and oil is penetrated into cotton net in length and breadth after the absorption of super-hydrophobic super-oleophylic layer, by
Through guiding cotton thread to enter outage after cotton thread is net guided in length and breadth.Wherein super-hydrophobic super-oleophylic layer is made of above-mentioned material, the material
Material is prepared as the prior art, is completed using the technology of patent CN201310676550.0, which discloses will be after the preparation
For super-hydrophobic super-oleophylic powder coating in filter paper or cotton fabric, disclosed mode belongs to the mode of surface coating, and of the invention
It is to be used as plate oil suction water proof infiltration structure, and its plate structure uses the form of thickness change, so that upper layer is saturated
Grease while descend lower layer mobile under gravity since the variation of size aggravates the concentration in the region of lower layer, thus just
In the guidance oil extraction of cotton net in length and breadth and guidance cotton thread.On the basis of above-mentioned design, the present invention not only can solve long-time service
Due to grease attachment caused by false alarm, moreover it is possible to solve in use process early period as oil smoke concentration it is excessive caused by wrong report
It is alert, since above structure does not have the adsorption effect to comburant particulate matter, it will not influence normal fire alarm.

Made of plate structure, thickness along interior collection cigarette cover 3 small-caliber ends be directed toward large diameter end direction be gradually reduced.
Design principle of the invention is as follows: in order to solve this wrong report phenomenon presented in background technique, we will make
Post analysis discovery is disassembled with the optical detector of fire smoke for being limited to 2 years or more year, since this kind of optical detector of fire smoke is located at kitchen,
The oil smoke that usually quick-fried generates can enter interior collection cigarette set 3, and due to the not persistently generation of oil smoke, within general 2 years
Optical detector of fire smoke when facing this kind of oil smoke, be difficult alarm phenomenon, but as time increases, part oil smoke meeting occur
It is particularly easy to be attached on 3 inner walls of interior collection cigarette set, as time increases, part dust will mix oil smoke and be attached to interior collection cigarette
It covers on 3 inner walls, and frequently forms protrusion, this phenomenon can make the light of reflection enter on photosensitive head, therefore, with the time
Increase, grease attachment point increases, and this reflex was originally more, and the light for causing photosensitive head to be experienced is more and more stronger, also got over
Therefore photosensitive head can be made to reach preset limit value immediately generating low concentration cooking oil smoke closer to preset limit value, because
And the case where this false alarm, is also more and more.In order to solve this problem, that is, it needs to solve to enter interior collection cigarette set 3 in oil smoke included
After its inner wall so that grease should not its inner wall for a long time stop, reduce grease and common dust mixing probability, with this
It reduces and forms the quantity for the protrusion that grease dust is mixed to form in inner wall, finally reduce the initial photosensitive value of photosensitive head, and on
The initial photosensitive value for stating photosensitive head in phenomenon is higher, very close threshold value.The application in order to achieve the above object, using collecting inside
Begin to rehearse oilhole 31 on cigarette set 3 to solve, and be provided with the outage 31 by it is a kind of it is inclined in a manner of be arranged, set according to above-mentioned inclination
Mode is set, can be flowed to after oil attachment with in-line arrangement oilhole 31 outside interior collection cigarette set 3, the attachment of 3 inner walls is covered without collecting cigarette inside, is passing
In system technology, although interior collection cigarette set 3 is located in outer exhaust fume collecting hood 2, the small-caliber end of outer exhaust fume collecting hood 2 will be far longer than interior collection cigarette set
3 large diameter end, that is, the large diameter end of interior collection cigarette set 3 has at least 10cm or so between the small-caliber end apart from outer exhaust fume collecting hood 2
Spacing, this construction meeting so that in the gap that part oil smoke both enters, and the present invention directly expands in collection cigarette cover 3 it is big
Bore end makes its size consistent with the small-caliber end of outer exhaust fume collecting hood 2, and the two forms zero clearance cooperation, therefore the two is direct
It is formed for storing the grease of above-mentioned outage 31, simultaneously as expanding the bore of interior collection cigarette set 3, therefore more oil smoke
It will enter in interior collection cigarette set 3, therefore aggravate the attachment number that interior collection cigarette covers grease on 3 inner walls, so that scattered grease
Grain is easier to collect, and then into outage 31, is played instead by the purpose of more grease discharges.In the present invention,
Middle outage 31 uses capillary, the study found that general cooking generates 3 quasi-grease particulate matters, one kind is that 10um deposits oil
Rouge particle, one kind are the inhalable fat particles of 0.01-10um, and one kind is gas molecule group, are contacted in food with high temperature oil
Moment, or generate largely can deposited fat particle and inhalable fat particles, and can deposited fat particle and inhalable oil
Rouge particle rises into optical detector of fire smoke with hot gas, if using outer exhaust fume collecting hood 2 and the set wide arc gap cooperation of interior collection cigarette
Scheme, largely can be therefore more in the gap that both will enter of deposited fat particle, without entering in interior collection cigarette covers
The number smaller inhalable fat particles of particle diameter can then enter interior collection cigarette set, the attachment under this design in interior collection cigarette set
Inhalable fat particles are more, and can deposited fat particle it is less, and the self weight of inhalable fat particles is small, and mobility is very
Difference, therefore be difficult to be discharged after runner formation collects, and the mounting means of above-mentioned zero clearance in the present invention is used, it can largely deposit oil
Rouge particle can also enter in interior collection cigarette set, with increasing for deposition, largely can deposited fat particle in the case where self weight with
It is adjacent can the mixing of deposited fat particle also mix short grained inhalable fat particles simultaneously, final confluence enters outage
31 discharges.
Due to change it is interior collection cigarette set and outer exhaust fume collecting hood matching relationship so that largely can deposited fat particle also enter
Interior collection cigarette set can aggravate the dust concentration in interior collection cigarette set, therefore also have certain probability and cause to report by mistake in the case
Alert, in order to solve this problem, the present invention should devise acceleration and absorb and form the structure of infiltration to solve, so that entering Nei Ji
The hollow region that fat particles in cigarette set can permeate rapidly without being gathered in interior collection cigarette set for a long time, reduces oil smoke with this
Granule density reduces the generation of false alarm.Its structure is the side wall permeable formation 15 that setting collects that cigarette covers 3 inner walls inside, the side wall
Permeable formation include be attached to interior collection cigarette cover the cotton nets in length and breadth of 3 inner walls, the super-hydrophobic super-oleophylic layer adjacent with cotton net in length and breadth and
