Embodiment
For above and other objects of the present invention, feature and advantage can be become apparent, cited below particularlyly go out preferred embodiment and conjunction with figs. is described in detail below.Hotness according to the present invention knows that the embodiment explanation of device will divide following three parts.At first describe [I] common example structure, second describes the feature of [II] this embodiment, and the last variation of describing [III] this embodiment.
The example structure that [I] is common
At first, common structure among the embodiment is described.According to this embodiment, hotness knows that device is set on the attaching surface of similar ceiling.This hotness knows that device comprises a hotness notice of invitation unit and an induction installation main body.Here, this hotness notice of invitation unit be one can be in monitor area the hot perceptron of sensing thermal source.This induction installation main body can judge whether fire alarm takes place based on the signal of this hotness notice of invitation unit output.Take place in case judge fire alarm, this induction installation main body starts a warning horn or declaration has situation to take place.This induction installation main body also comprises a control module and a framework.This control module can determine whether starting warning horn according to having or not of fire alarm.Framework is the framework that this hotness is known device.
According to embodiment, this hotness knows that device comprises a protective device.This protective device can be protected by framework and be fixed on hotness notice of invitation unit on the protective device.The purpose of protection is in order to absorb the distortion of this hotness notice of invitation unit, with and/or prevent that predetermined material from entering into this hotness notice of invitation unit from monitor area.
In conventional apparatus, hotness notice of invitation unit and framework are fixed by whole respectively by adhesive agent.When such structure is used in the hotness that ceramic component is used as sensing cell when knowing device, if owing to the thermal expansivity of hotness notice of invitation unit and framework around the change of temperature and/or air pressure change down when making framework or hotness know the device distortion, may on hotness notice of invitation unit that the agent that gets adhered is fixed and the interface between framework, produce stress.This stress that produces in hotness notice of invitation unit will influence the output of hotness notice of invitation unit because of piezoelectric effect, make hotness notice of invitation unit possibly can't correctly sense thermal source.In addition, hotness notice of invitation unit may fall down from framework.Further, one of them therefore damage of hotness notice of invitation unit and framework.
Further, in the superincumbent structure, thermal source is delivered to the framework with big thermal capacity from the hotness notice of invitation unit of sensing thermal source.Therefore, the thermal response of hotness notice of invitation unit can reduce.In simple terms, the heat transmission from hotness notice of invitation unit to framework can make the thermal response of hotness notice of invitation unit degenerate.
In an embodiment of the present invention, because the distortion of the different hotness notice of invitation units that cause with framework (or similar device) thermal expansivity of hotness notice of invitation unit has been slowed down, thereby improved the binding fiduciary level of the sensing precision of hotness notice of invitation unit and hotness notice of invitation unit and framework, and improved the thermal response of hotness notice of invitation unit further, thereby increased the fiduciary level of hotness notice of invitation unit.
Especially in an embodiment, one thin structure is used in hotness notice of invitation unit and the framework, thereby can be absorbed by the different thermal pressures that cause of hotness notice of invitation unit, cause the distortion of hotness notice of invitation unit and framework to be absorbed because temperature rises thus with the thermal expansivity of framework.Therefore, this structure in order to absorption stress can make the heat conduction from hotness notice of invitation unit to framework diminish.Further,, expand or shrink and make that hotness notice of invitation unit can distortion because be sealed in gas in the hotness notice of invitation unit, and such distortion can be absorbed or/and during temperature variation in air pressure.
Further, in an embodiment, hotness notice of invitation unit and framework be not by adhesive agent but melt each other and fix, thereby can realize the binding between hotness notice of invitation unit and the framework more easily.For instance, the lamellar member in the hotness notice of invitation unit is melted and attaches on the framework.
When ferroelectric material is actually used in hotness and knows in the element,, must need an encapsulating structure and guarantee that enough environmental resistances are arranged in order to keep the thermal response of ferroelectric material.In order to ensure the thermal response of ferroelectric material, ferroelectric material preferably is directly exposed in the monitor area as far as possible, so that variation of temperature can directly be sent to ferroelectric material in monitor area.Yet, when ferroelectric material only is exposed in the monitor area, may twist ferroelectric material, or enter into hotness from monitor area and know that the various materials of device may reduce or corrode ferroelectric material from the monitor area externally applied forces.
In an embodiment, will realize two different purposes simultaneously, for example, keep the thermal response and the protection ferroelectric material of ferroelectric material.
The feature of [II] embodiment
Next, know the embodiment of device with describing hotness.Yet the embodiment of it should be noted that the present invention is not limited thereto.
First embodiment:
First embodiment is at first described.As shown in the figure, according to first embodiment, one hotness knows that the principal character of device is to be fixed on the film like member by glued membrane, and hotness notice of invitation unit can be attached on the framework by lamellar member, and hotness notice of invitation unit can be exposed in the monitor area by this lamellar member.
When Fig. 1 was hotness notice of invitation unit binding framework state, hotness was known the side view of device 1.Fig. 2 is a hotness notice of invitation unit with before framework combines, and hotness is known the side view of device 1.As Fig. 1 and shown in Figure 2, hotness knows that device 1 comprises hotness notice of invitation unit 11 and one induction installation main body 21.
The structure of hotness notice of invitation unit 11 will be described below.Fig. 3 shows by the plane and the side-looking graph of a relation of the hotness notice of invitation unit of sheet members double team, and Fig. 4 has shown that the plane of hotness notice of invitation unit and side-looking are in conjunction with figure.Hotness notice of invitation unit 11 be can be in monitor area the thermal sensor of sensing thermal source, and comprise sensing cell 30, metal electrode 40 and metal electrode 50.Sensing cell 30 is the sensors that a sense conditions can be converted to another state variation, for instance, and the lamellar thermal sensor that it is made up of a film like ferroelectric material.When in the monitor area during temperature variation, ferroelectric material is exported burnt electric electric current because of burnt electrical effect.Metal electrode 40 and the 50 burnt electric currents that sensing cell 30 provided via a coil or similar device export induction installation main body 21 to.
Sensing cell 30, metal electrode 40 and 50 can form three layer structures.Metal electrode 50 and 40 is separately positioned on the outside (monitor area one side, below also with) of sensing cell 30 and the inboard of sensing cell 30 (from the farther side of monitor area, below also with).Sensing cell 30, metal electrode 40 are thin plate-like haply with metal electrode 50, and round concentrically with respect to one another haply storehouse.Herein, metal electrode 40, sensing cell 30 increase gradually to the diameter of metal electrode 50.Sensing cell 30 is bonded on the metal electrode 50 by viscose, and metal electrode 40 vapour depositions are on sensing cell 30.
In fact, outer sheet members 61 and interior sheet members 62 can be formed and any dimension arranged by any material.For instance, under the situation of considering intensity, stress absorption characteristic, plasticity and thermal response, outer sheet members 61 can be formed by resin, and has 0.2 millimeter or littler thickness.Similarly, interior sheet members 62 can be formed by resin, and has 0.05 millimeter or littler thickness.Outer sheet members 61 is can bear 85 ℃ temperature fully or surpass operating temperature and the resin temperature of fusion that hotness is known device 1 with the maximum temperature limit of interior sheet members 62.
Therefore, as shown in Figure 3, interior sheet members 62 has a circumscribed part 62a.Specifically, circumscribed part 62a is the U type curve at the center that switches to outside the cylindrical of interior sheet members 62 haply.Herein, when an electric wire that is electrically connected to a control module (not shown) or similar device can directly weld the metal electrode 40 that partly exposes from circumscribed part 62a and 50, hotness notice of invitation unit 11 and control module (not shown) can be electrically connected.
Next, will the structure of induction installation main body 21 be described.Induction installation main body 21 comprises a control module (not shown) and a framework 81.Control module is a control device, and it can receive burnt electric current, the comparison burnt an electric current and the predetermined critical that produce from hotness notice of invitation unit 11, judge whether fire alarm takes place and start a warning horn according to the result of this judgement.For instance, control module is made up of an integrated circuit (IC) and the program that an IC carries out, and carries out predetermined control.
Next, the syndeton of hotness notice of invitation unit 11 with framework 81 will be further described.The connection surface portion 81a of framework divides 81d to form by an opening 81c and a junction.Opening 81c haply be connected surface portion 81a and be concentric circles, and be a discoid haply opening.The external diameter of opening 81c is defined so that littler and bigger than the diameter of metal electrode 50 than the diameter of outer sheet members 61.Therefore, when hotness notice of invitation unit 11 was pulled to connected surfaces part 81a from the outside, the part of the hotness notice of invitation unit 11 beyond sheet members 61 can be arranged in the framework 81 by opening 81c.Therefore, hotness notice of invitation unit 11 is protected by framework 81.Simultaneously, the outer sheet members 61 of hotness notice of invitation unit 11 can be pushed to and be engaged on the connected surfaces part 81a, makes hotness notice of invitation unit 11 to be fixed in the framework 81 through connected surfaces part 81a.
In addition, the outer edge part 81e of framework 81 more stretches out than connected surfaces part 81a.Outer edge part 81e is formed so that big or small together with the internal diameter of outer sheet members 61 haply, and perhaps the internal diameter than outer sheet members 61 is big a little.Therefore, in the time of in the middle of outer sheet members 61 is arranged on the inside surface of outer edge part 81e and connected surfaces part 81a, framework 81 is promptly aimed at outer sheet members 61, and outer sheet members 61 is promptly suitably kept.
As shown in Figure 2, at the outer surface of connected surfaces part 81a, a linking portion 81d is formed.Linking portion 81d be melt portions so that hotness notice of invitation unit 11 attaches to framework 81, and linking portion 81d forms a ring-type protrusion, is concentric circles with connected surfaces part 81a haply.Therefore, as shown in Figure 1, be linked to the outer surface of connected surfaces part 81a when the inner surface of outer sheet members 61, and when linking portion 81d melts with ultrasonic or thermal source, linking portion 81d is attached on each other with the linking portion 61a with respect to the outer sheet members 61 of linking portion 81d, and hotness notice of invitation unit 11 attaches in the framework 81 by fusing thus.Therefore, linking portion 61a and linking portion 81d form a connector, make hotness notice of invitation unit 11 be connected to each other with framework 81.
Therefore hotness notice of invitation unit 11 only is connected with framework 81 by the outer sheet members 61 of a lamellar member.Especially, as shown in Figure 1, formed a gap W in the middle of the marginal portion of framework connected surfaces part 81a and the interior sheet members 62.Therefore, during temperature variation, outer sheet members 61 can absorb the 11 different distortion that produce with the thermal expansivity of framework 81 because of hotness notice of invitation unit around.Therefore, can avoid sensing cell 30 distortion by the electric field that piezoelectric effect produced, it can avoid hotness notice of invitation unit 11 to break down.Further, can avoid hotness notice of invitation unit 11 to drop and the loss of hotness notice of invitation unit 11 and/or framework 81 from framework 81.
Further, because interior sheet members 62 is an elasticity mucous membrane glue, but its stationary heat perception unit 11 outside on the sheet members 61, so hotness notice of invitation unit 11 directly is not fixed on outer sheet members 61.Therefore, hotness notice of invitation unit 11 can move to lateral on a small quantity with respect to this outer sheet members 61, and the distortion in the two can be absorbed.
Therefore, when hotness notice of invitation unit 11 links together with framework 81, have only metal electrode 50 and outer sheet members 61 to be exposed in the middle of the sensing cell 30 and monitor area of hotness notice of invitation unit 11.Metal electrode 50 combines thinner than traditional framework with the thickness of bonding agent with the thickness that combines of outer sheet members 61.Therefore, it is just easier that the thermal source of monitor area is sent to hotness notice of invitation unit 11.In addition, outer sheet members 61 is that the resin by the less pyroconductivity of tool forms, and suppressing heat conduction, that is the thermal source from hotness notice of invitation unit 11 to framework 81 runs off.As a result, can improve the thermal response of hotness notice of invitation unit 11.
In addition, because linking portion 81d is made up of a boss thing in above-mentioned connecting structure, therefore linking portion 81d also forms with connected surfaces part 81a after fusing and roughly is concentrically ringed tubular shape, therefore can be by closing the gap in the middle of hotness notice of invitation unit 11 and the framework 81 around its whole plane.Because hotness notice of invitation unit 11 is melted and the adhesive force sealing by linking portion 61a and linking portion 81d with framework 81, so can prevent to enter framework 81 inside from monitor area via opening 81c as the extraneous thing of dust and moisture.Herein, linking portion 61a and 81d are corresponding to the described protective device of appended claims.
In addition, the binding of hotness notice of invitation unit 11 and framework 81 is melted via the linking portion 81d of the linking portion 61a of outer sheet members 61 and connected surfaces part 81a and is sticked and realize.This fusing is finished in the cycle at shorter time with the comparable traditional technology of sticking of technology of sticking.Be different from traditional technology, temporarily stationary heat perception unit is hardened dispensablely up to adhesive in framework, and technology becomes and is more prone to carry out.In addition, the management of adhesive for example storage and processing becomes unnecessary, so the production hotness knows that the efficient of device 1 can improve.
According to first embodiment, because the framework that the different thermal expansivity that can prevent hotness notice of invitation unit and framework or similar material is produced during the temperature and pressure variation around and the distortion of hotness notice of invitation unit, thereby can prevent that hotness notice of invitation unit from breaking down.Further, can prevent hotness notice of invitation unit to drop and the consume of hotness notice of invitation unit and/or framework from framework.
According to first embodiment, owing to hotness notice of invitation unit runs off and can reduce to the heat of framework, so can improve the thermal response of hotness notice of invitation unit.
Second embodiment:
Second embodiment will be described.According to second embodiment, hotness knows that device has same feature with first embodiment haply.Know that according to the hotness of second embodiment principal character of device is that hotness notice of invitation unit is attached in the framework via the pressure absorber, and hotness notice of invitation unit is exposed in the monitor area directly.When not describing particularly, the hotness of second embodiment knows that device and first embodiment are similar, and similar elements will adopt the Reference numeral identical with first embodiment, and description wherein will can not be repeated.
Fig. 5 is the side view that hotness that hotness notice of invitation unit combines with framework is known device 2, and Fig. 6 to be the hotness notice of invitation first combines the side view that preceding hotness is known device 2 with framework.Hotness knows that device 2 comprises a hotness notice of invitation unit 12, an induction installation main body 22 and a liner 90, but does not comprise sheet segment 60.Liner 90 is protective devices, and it prevents that external substance such as dust and moisture from entering in the framework 82 from monitor area.
With the structure of describing according to the hotness notice of invitation unit 12 of second embodiment.Fig. 7 is the plane and the side-looking graph of a relation of hotness notice of invitation unit 12.Hotness notice of invitation unit 12 comprises a metal electrode 51, and it is positioned at the position as the first embodiment metal electrode 50.Metal electrode 51 has hole 51a.In Fig. 7, metal electrode 51 has six hole 51a, yet the quantity of hole 51a is not exceeded with six.Hole 51a is arranged on the marginal portion of metal electrode 51.The marginal portion that hole 51a forms is formed by the extension of sensing cell 30 neighborings.Hole 51a uniformly-spaced arranges along the concentric circles of metal electrode 51 haply.The effect of hole 51a is treated and can will be described.
With the liner of describing according to second embodiment 90.Fig. 8 is the plane and the side-looking graph of a relation of liner 90.Liner 90 has a thin ring-type haply.Form hole 90a at the edge of liner 90, it is haply corresponding to the same interval location of the hole 51a of metal electrode 51.For example, liner 90 is made up of rubber.The function of liner will be treated and can describe.
Then, will the structure of induction installation main body 22 be described.Induction installation main body 22 comprises a framework 82, and it is positioned on the position of framework 81 of first embodiment.As Fig. 5 and shown in Figure 6, framework 82 comprises a connected surfaces part 82a, and it is positioned at the position as the first embodiment connected surfaces part 81a.Connected surfaces part 82a is haply for thin plate-like and to be formed on inner side edge adjacent in the lower marginal portion of framework 82.
Hotness notice of invitation unit 12 will be described in further detail with the syndeton of framework 82.The connected surfaces part 82a of framework 82 comprises a pressure absorber 82b, an opening 82c and a protuberance 82f.Though Fig. 6 only shows two protuberance 82f, yet in fact can form more a plurality of protuberance 82f, for instance, six protuberance 82f.
Therefore, when protuberance 82f was inserted into the hole 90a of liner 90, liner 90 can be close to framework 82.In addition, when protuberance 82f inserted the hole 51a of metal electrode 51, metal electrode 51 can be close to liner 90.Protuberance 82f is melted part, by fusing hotness notice of invitation unit 12 is attached on the framework 82.When protuberance 82f melts via ultrasonic or heat, and framework 82, liner 90 be when tightly linking together with hotness notice of invitation unit 12, and as shown in Figure 5, protuberance 82f attaches to hole 51a, can couple together hotness notice of invitation unit 12 and framework 82 via liner 90 thus.Therefore, protuberance 82f and hole 51a form a connector, can hotness notice of invitation unit 12 is together connected to each other with framework 82.
Therefore hotness notice of invitation unit 12 only links by pressure absorber 82b and framework 82.More particularly, as shown in Figure 5,12 protuberance 82f parts by framework 82 of hotness notice of invitation unit link with framework 82, and protuberance 82f forms on pressure absorber 82b.Because pressure absorber 82b approaches, so the distortion of framework 82 and can being absorbed by the 82 different distortion that thermal expansivity caused of hotness notice of invitation unit 12 and framework during variation of temperature around.Therefore, sensing cell 30 distortion can be avoided, and the fault of hotness notice of invitation unit 12 can be avoided by electric field that piezoelectric effect produces.Further, can avoid hotness notice of invitation unit 12 from drop loss with hotness notice of invitation unit 12 and/or framework 82 of framework 82.
Therefore, by the top syndeton of mentioning, make thermal source directly to be received by this metal electrode 51 from monitor area.The thickness of metal electrode 51 can be a little than the thin thickness of this tradition framework and adhesive agent combination.In addition, because not having the hotness of first embodiment, sensing cell 30 do not know the included sheet segment of device 60, so the thermal capacity of sensing cell 30 can further reduce, transmit to promote heat, thereby the thermal response of hotness notice of invitation unit 12 can increase from monitor area to this hotness notice of invitation unit 12.
The external diameter of liner 90 is onesize with the external diameter of metal electrode 51 haply, perhaps is slightly larger than the external diameter of metal electrode 51.Therefore, when liner 90 in succession in this hotness notice of invitation unit 12 and when being fixed on the framework 82, the outside side joint of liner 90 is connected on the framework 82 at least, liner 90 can close the gap between hotness notice of invitation unit 12 and the framework 82 thus.
As a result, by the top syndeton of mentioning, hotness notice of invitation unit 12 is connected to each other with framework 82 and can be sealed by liner 90, so can prevent will enter framework 82 inside via opening 82c from monitor area as the external substance of dust and moisture.Therefore, as described above, liner 90 is with respect to the protective device of appending claims.
In addition, hotness notice of invitation unit 12 can realize that it forms sticking together between raised part 82f and hole 51a by fusing protuberance 82f with being connected of 82 of frameworks.Fusing and the comparable traditional technology of sticking of technology of sticking are finished in shorter time.Be different from traditional technology, the present invention does not need temporarily that stationary heat perception unit is hardened up to adhesive in framework, and technology becomes and is more prone to carry out.In addition, the management of adhesive is for example stored and processing becomes unnecessary, can improve the production efficiency that hotness is known device 2 thus.
Therefore, except the effect of first embodiment, second embodiment can obtain more effect, and this is because hotness notice of invitation unit is sealed with framework, so the external substance that enters in framework or the sensing cell from monitor area can be prevented.
The 3rd embodiment:
The 3rd embodiment will be described.Know that according to the hotness of the 3rd embodiment device has the feature as first embodiment haply.In addition, know that according to the hotness of the 3rd embodiment the main hotness notice of invitation unit that is characterised in that of device is exposed in the monitor area via the pressure absorber of framework.When not describing particularly, hotness knows that the element of device and first embodiment are similar among the 3rd embodiment, and same element will adopt the Reference numeral identical with first embodiment, and description wherein will no longer repeat.
Fig. 9 is the side view that hotness that hotness notice of invitation unit combines with framework is known device, and Figure 10 to be the hotness notice of invitation first combines the side view that preceding hotness is known device with framework.Hotness knows that device 3 comprises hotness notice of invitation unit 12 and one induction installation main body 23.
Then, will the structure of induction installation main body 23 be described.Induction installation main body 23 comprises the framework 83 of the framework 81 that replaces first embodiment.Figure 11 is that the framework main body combines preceding framework side view with the first adjunct unit of hotness notice of invitation.As shown in figure 11, framework 83 comprises a framework main body 84 and a hotness notice of invitation unit adjunct unit 85 with hotness notice of invitation unit 12.Framework main body 84 has an adjunct unit 84a.In addition, hotness notice of invitation unit adjunct unit 85 comprises an adjunct unit 85a and a connected surfaces part 83a.Herein, adjunct unit 84a and 85a are connector, and it can connect hotness notice of invitation unit adjunct unit 85 to framework main body 84.
Framework main body 84 is formed by resin mold stream respectively with the first adjunct unit 85 of hotness notice of invitation, and hotness notice of invitation unit adjunct unit 85 flows be bonded to each other adjunct unit 84a and 85a with framework main body 84 by inserting mould.Reach above-mentioned method of attachment following reason is arranged.Know the thermal response of device 3 in order to increase hotness, must make the connected surfaces part 83a that is positioned at hotness notice of invitation unit 12 and monitor area centre thinner, to reduce the thermal capacity of connected surfaces part 83a.Yet the structure with collective modes stream of film portion is difficult to reach.Therefore, the film portion that the adjunct unit 85 of hotness notice of invitation unit has is formed by resin mold stream, and then forms framework main body 84 by injecting resin mold stream respectively, therefore injects mould stream thus and can deal with problems.As a result, framework 83 can be made and the yield of framework 83 can be enhanced easily.The adjunct unit 85 of hotness notice of invitation unit is with respect to the adjunct unit of appending claims.Perhaps, the adjunct unit 85 of framework main body 84 and hotness notice of invitation unit can and stick and integrally formed via fusing, but not is shaped by injecting mould stream.
Then, hotness notice of invitation unit 12 will be described in further detail with the syndeton of framework 83.Connected surfaces part 83a is being formed near the lower peripheral part inner side edge of adjunct unit 85a correspondence by the adjunct unit 85 of this hotness notice of invitation unit, and has a disc shaped haply.Connected surfaces part 83a comprises a pressure absorber 83b and a protuberance 83f.Pressure absorber 83b has haply with connected surfaces part 83a and is concentrically ringed disc shaped haply, and its inner surface is set to make pressure absorber 83b more thinner than connected surfaces part 83a.The thickness of pressure absorber 83b does not have special signals.Yet, considering that the thickness of pressure absorber 83b is 0.2 millimeter or littler under intensity, pressure absorption characteristic, plasticity and the thermal response.The external diameter of pressure absorber 83b is slightly larger than the external diameter of metal electrode 51.
The length on the rank that the border produced between pressure absorber 83b and connected surfaces part 83a is than longer a little in conjunction with length at thickness direction of metal part 51 and sensing cell 30.When metal part 51 and sensing cell 30 during by inboard pile-up pressure absorber 83b, metal part 51 can be placed in by in connected surfaces part 83a and the formed space of pressure absorber 83b with sensing cell 30, and the position of sensing cell 30 can be determined haply thus.Herein, pressure absorber 83b is with respect to the pressure absorber of appending claims.Protuberance 83f is identical with the protuberance 82f of second embodiment.As Figure 10 and shown in Figure 11, and though only show two protuberance 83f, more protuberance 83f in fact can be formed, for instance, six protuberance 83f.
Herein, when with protuberance 83f patchhole 51a, the outer surface of metal electrode 51 can be close to framework 83.Protuberance 83f is melted part, thereby by fusing hotness notice of invitation unit 12 is attached on the framework 83.When protuberance 83f was made as shown in figure 10 that by the fusing of ultrasonic or thermal source framework 83 and hotness notice of invitation unit 12 are close to together, protuberance 83f was melted and attaches on the 51a of hole, can couple together hotness notice of invitation unit 12 and framework 83 thus.Therefore, protuberance 83f and hole 51a can form a connector, and unit 12 is together connected to each other with framework 83 with the hotness notice of invitation.
Hotness notice of invitation unit 12 links by pressure absorber 83b and framework 83.More particularly, 12 protuberance 83f parts by framework 83 of hotness notice of invitation unit link with framework 83, and as shown in figure 10, and protuberance 83f is formed on the pressure absorber 83b.Because pressure absorber 83b approaches, the distortion of framework 83 and can being absorbed by the 83 different distortion that thermal expansivity caused of hotness notice of invitation unit 12 and framework during variation of temperature around.Therefore, sensing cell 30 distortion can be avoided, and the fault of hotness notice of invitation unit 12 can be avoided by electric field that piezoelectric effect produces.Further, can avoid hotness notice of invitation unit 12 from drop loss with hotness notice of invitation unit 12 and/or framework 83 of framework 83.
Therefore, when hotness notice of invitation unit 12 is connected in framework 83, have only metal electrode 51 and pressure absorber 83b to be positioned in the middle of the sensing cell 30 and monitor area of hotness notice of invitation unit 12.Therefore, metal electrode 51 and pressure absorber 83b combine thickness than traditional framework and adhesive agent to combine thickness obviously thinner.Therefore, the thermal capacity middle at sensing cell 30 and monitor area becomes littler, impels from the heat of monitor area to be converted to hotness notice of invitation unit 12.As a result, the thermal response of hotness notice of invitation unit 12 can increase.
In addition, hotness notice of invitation unit 12 can realize that it can cause protuberance 83f to be adhered to hole 51a as mentioned above by fusing protuberance 83f with being connected of framework 83.The comparable traditional technology of sticking of the fusing and the technology of sticking is finished in during shorter time.Be different from traditional technology, the present invention does not need temporarily that stationary heat perception unit is hardened up to adhesive in framework, and technology becomes and is more prone to carry out.In addition, the management of adhesive is for example stored and processing becomes unnecessary, can improve the production efficiency that hotness is known device 3 thus.
In addition, as mentioned above, framework 83 is that the injection mould by the hotness notice of invitation unit adjunct unit 85 with pressure absorber 83b flows in framework main body 84 and forms.Mould stream with hotness notice of invitation unit adjunct unit 85 of pressure absorber 83b is gone back simple than the whole mould stream of the framework 83 with pressure absorber 83b.Therefore, above-mentioned technology can be improved the output of framework 83, therefore also can improve the yield-power that hotness is known device 3.
Therefore, according to the 3rd embodiment, because the pressure absorber can form respectively and be attached to framework, so framework can be made easily.Therefore, has the output of improving framework and the usefulness of yield-power according to the 3rd embodiment, as the usefulness of first embodiment.
The 4th embodiment:
The 4th embodiment will be described.At the 4th embodiment, this side surface is the side that is positioned at monitor area, and is a lamellar member, and it is blocked device haply and covers.When specifically not indicating, the hotness of the 4th embodiment knows that the element of device and first embodiment are similar, and components identical will be representing as the identical Reference numeral of first embodiment, and description wherein will no longer repeat.
Figure 12 is a side view of knowing device according to the hotness of the 4th embodiment, and Figure 13 is that hotness notice of invitation unit combines the side view that preceding hotness is known device with its peripheral part and framework.Hotness knows that device 1 comprises a hotness notice of invitation unit 11, a leaf membrane 60, diaphragm 100 and induction installation main body 110, and is fixed on the attaching surface of similar ceiling C.
In these elements, hotness notice of invitation unit 11 is formed by sensing cell 30 thin layers, and metal electrode 40 and 50 and first embodiment are similar.Outer sheet members 61 and interior sheet members 62 are formed these sheet segments 60, and its double team hotness notice of invitation unit 11, to avoid from the external force of monitor area and/or entering of corrosion thing.Like this, sheet segment 60 is just as the device that blocks of protection hotness notice of invitation unit 11.In addition, as later description, hotness notice of invitation unit 11 can be fixed on framework 111 via sheet segment 60.Like this, the function of sheet segment 60 is just as the fixed cell of stationary heat perception unit 11 to framework 111.The details of sheet segment 60 will describe as after.
On the side surface of sheet members 61, promptly the side of monitor area has a diaphragm 100 outside.Diaphragm 100 can avoid predetermined substance to enter hotness notice of invitation unit 11 from monitor area, and diaphragm 100 is corresponding to the device that blocks of appending claims.The details of diaphragm 100 will describe as after.
Then, will the structure of induction installation main body 110 be described.When specifically not indicating, the structure of induction installation main body 110 is similar to the main part of known induction installation.Induction installation main body 110 comprises a control module (not shown) and framework 111.
Control module can be accepted burnt electric current from hotness notice of invitation unit 11, and more burnt electric current and predetermined value just can determine whether fire alarm takes place, and decides startup one warning horn according to the result.For instance, control module is made of integrated circuit (IC) and the performed program of IC, and carries out predetermined control.
Be fixed on the framework 111 owing to outer sheet members 61 can directly melt, beyond sheet members 61 haply preferably by being formed with the same-type resin that is used to do framework 111.Herein, " of the same type haply " means the type and have same characteristics in certain scope, to guarantee that outer sheet members 61 and framework 111 are in fusing with stick the compatibility that has in a way.When outer sheet members 61 and framework 111 fully by forming with the resin of the same form of resin; Or outer sheet members 61 and framework 111 form by dissimilar resins, and under identical basis, every kind of resin comprises different adjuvants; Or under different situations, form resin by identical materials; This we can say that they are made up of the resin of " of the same type haply ".For instance, if framework 111 is made up of polycarbonate, outer sheet members 61 also can be made up of the polycarbonate glued membrane.
Then, will further describe diaphragm 100.Diaphragm 100 can avoid predetermined substance to enter hotness notice of invitation unit 11 from monitor area, and corresponding to the device that blocks of appending claims.Herein, any material that can reduce or corrode the single or various ways of hotness notice of invitation unit 11 can be " predetermined substance ", and diaphragm can elect according to predetermined substance.For instance, if the predetermined substance material is a moisture, and the humidity check glued membrane that can avoid moisture to enter can be selected to as diaphragm 100.Perhaps, if scheduled material supposition is corrosive gas (sulphuric dioxide (SO for example
2), hydrogen sulfide (H
2S), nitrogen dioxide (NO
2) and chlorine (Cl
2)), the fluorocarbon resin glued membrane can be selected to invade to prevent etchant gas as diaphragm 100.
The major function effect of the above-mentioned diaphragm of mentioning 100 is as follows.Sheet segment 60 is just as the device that blocks of protection hotness notice of invitation unit 11.Yet but sheet segment 60 has the function of a stationary heat perception unit 11 to the fixed cell of framework 111.Therefore, when considering the common tackness of outer sheet members 61 and framework 111, the best haply resin by same form of outer sheet members 61 and framework 111 constitutes.Then, using outside, the material of sheet members 61 is limited significantly.In addition, in order to keep the heat transfer effect from monitor area to hotness notice of invitation unit 11, outer sheet members 61 is thin as far as possible.So, the shape of outer sheet members 61 also is limited.Because the material of these thin slices and restriction in shape, it is difficult avoiding the outer sheet members 61 of moisture and/or gas travels through fully.In addition, when the adhesive agent of high osmosis during with the sticking together mutually of sheet members 61 outside and interior sheet members 62, adhesive agent may comprise aqueous vapor and enter outer sheet members 61.Moisture and/or gas may pass through outer sheet members 61 and touch this hotness notice of invitation unit 11 then.In this example, metal electrode 40 and/or 50 may be oxidized, or sensing cell 30 may be corroded.In other example,, may form short circuit if moisture enters in sensing cell 30 and metal electrode 40 or 50.Therefore, in order to protect hotness notice of invitation unit 11, can outside sheet segment 60, provide second structure that forms by diaphragm 100.
Therefore, according to the 4th embodiment, the diaphragm 100 above the outer sheet members 61 can avoid predetermined substance to enter hotness notice of invitation unit 11 from monitor area, so hotness notice of invitation unit 11 can avoid degenerating and/or corrosion.Particularly when moisture check glued membrane is used in diaphragm 100, avoided moisture to enter hotness notice of invitation unit 11, avoided the aging and short circuit of hotness notice of invitation unit 11 thus, and hotness knows that the fiduciary level of device 4 can keep the long cycle.In addition, be used on the diaphragm 100 owing to can not prevent the thin slice that heat is transmitted, so the thermal response of hotness notice of invitation unit 11 can be maintained on the high level.So, two purposes of giving shield mutually, i.e. maintaining heat reaction and protection hotness notice of invitation unit 11 can be reached simultaneously.In addition, be used in than outer sheet members 61 more on the position near monitor area because have the diaphragm 100 of above-mentioned functions effect, therefore outer sheet members 61 can be protected equally.
