The power lamp 270 is connected to the PCB 220 The power switch 280 is a switch for testing whether power is supplied to the FPC board 220. The power switch 280 is a switch for testing whether power is supplied to the FPC board 220 or not.

The battery 230 is installed in the housing 210 to cut off a part of the PCB 220 and to supply power to the PCB 220 while being inserted into the cut- The terminal 231 of the battery 230 is connected to the battery connector 221 to supply power to the PCB 220. Here, the battery 230 may be a disposable battery or a rechargeable battery (rechargeable battery).

The lid 240 seals the upper portion of the housing 210 to protect components installed inside the housing 210. The housing 210 is coupled to the housing 210 by screws Can be combined.

A vent hole 241 is formed in the outer circumferential surface of the lid 240 to allow external hot air to flow therein and an alarm sound of the speaker 250 built in the lid 240 is smoothly transmitted to the outside A speaker hole 242 is formed so as to be discharged.

A lamp hole 243 may be formed on the upper surface of the lid 240 so that the light of the power source lamp 270 may be radiated to the outside of the lid 240. In order to operate the power switch 280 of the PCB 220, An operation button 244 may be formed. The operation button 244 is configured to incise a part of the lid 240 so as to be elastically manipulated up and down.

FIG. 4 is an exploded perspective view of a fire extinguisher having a fire sensing unit according to a second embodiment of the present invention, and FIG. 5 is an assembled perspective view of FIG.

In addition to the configuration of the first embodiment, the second embodiment of the present invention is further provided with a smoke sensing member 300 for sensing the combustion gas generated when a fire occurs.

The smoke sensing member 300 includes a dark room case 310 having a smoke inlet hole 311 through which the smoke flows into the outer circumferential surface and having a smoke collecting chamber 312 therein, A light blocking protrusion 320 formed in a radial direction and a smoke detection sensor 330 for detecting smoke trapped in the dark room case 310.

The light blocking protrusions 320 are formed in the shape of a comb-like pattern in the interior of the dark room case 310, that is, the inside of the smoke inflow hole 311, so as to prevent fine dust and small Shielding the insects from entering, and effectively shielding the light coming from the outside. Even if minute light enters, the light having directivity hits the light blocking protrusion 320 to attenuate the intensity of the light. And a detection error of the detection sensor 330 is prevented.

The smoke detection sensor 330 may include a light emitting sensor 331 and a light receiving sensor 332. The smoke collecting chamber 312 may be formed of a light emitting diode, The smoke density is detected and it is judged whether or not the fire is present.

In the above description, heat sensing, heat sensing, and smoke sensing are simultaneously performed by the fire sensing unit. However, it is needless to say that only the unit for sensing smoke may be installed alone.

FIG. 6 is a diagram illustrating another embodiment of the present invention, which is provided in the injection port of the fire extinguisher 1 to ignite the fire extinguishing liquid by electrical shock to automatically fire the fire extinguishing liquid, The igniter main body 410 having an internal space as an empty space; An ignition space 421 is formed in the ignition device body 410 to receive the extinguishing liquid therein. The inside of the ignition space 421 prevents short-circuiting by the electrode extension portion 415, An ignition structure 420 coated with a ceramic material; An ignition controller 412 disposed at one side of the igniter main body 410; A sensing sensor 413 connected to the ignition controller 412 and disposed at one side of the igniter main body 210 to sense smoke or heat; A DC power supply unit 414 provided at one side of the ignition device body 210 to supply power to the detection sensor unit 413 and the ignition control unit 412; An electrode extension part 415 extended to the ignition space of the heat sink 420; And a nichrome wire 417 coupled to an end of the electrode extension part 415.

The operation of this configuration is as follows.

In the ignition space 421 of the ignition structure 420, the ignition structure 420 is screwed to the fire extinguisher 1 after filling with the extinguishing liquid. At this time, the detection sensor unit 413 checks whether the smoke is detected or the temperature is abnormally raised by the power source at all times or the power source of the DC power source unit 414.

If a fire occurs and smoke is generated and high temperature heat is generated, the detection sensor unit 413 provided in the main body 410 of the fire extinguisher ignition member 400 senses this.

If it is determined that the signal detected by the detection sensor unit 143 is a fire, the ignition control unit 412 is controlled.

The current of the DC power source section 414 is heated by the ignition control section 412 while the Nichrome wire 417 is heated through the electrode extension section 415. [

The digested liquid contained in the ignition space 421 is ignited by the heated nichrome wire 417 and the digestion liquid in the digestion tank 1 is burned by the ignited digestive fluids to generate smoke. At this time, since the inside of the ignition space 421 is coated with a ceramic material, short-circuiting is prevented.

Therefore, the oxygen around the flame is blocked by the smoke ejected from the inside of the fire extinguisher container 1, thereby suppressing the fire.

Meanwhile, the lid 240 may be formed of a polypropylene resin composition having excellent impact resistance against external impact or external environment. The polypropylene resin composition comprises a polypropylene random block copolymer composed of 75 to 95% by weight of an ethylene-propylene-alphaolefin random copolymer and 5 to 25% by weight of an ethylene-propylene block copolymer having an ethylene content of 20 to 50% by weight .

The polypropylene random block copolymer is preferably 75 to 95% by weight of the ethylene-propylene-alphaolefin random copolymer and 5 to 25% by weight of the ethylene-propylene block copolymer. The ethylene- When the content of the ethylene-propylene block copolymer is less than 5% by weight, the impact resistance is deteriorated. When the content of the ethylene-propylene block copolymer is more than 25% by weight, the rigidity is deteriorated do.

Wherein the ethylene-propylene-alpha olefin random copolymer comprises 0.5 to 7% by weight of ethylene and 1 to 15% by weight of an alpha-olefin having 4 to 5 carbon atoms and improves mechanical stiffness and heat resistance of the polypropylene resin composition, As shown in Fig. The ethylene content is preferably from 0.5 to 5% by weight, more preferably from 1 to 3% by weight. When the content of ethylene is less than 0.5% by weight, the whitening resistance is deteriorated. When the content is more than 7% by weight, .

Further, the alpha olefin means any alpha olefin except ethylene and propylene, and is preferably butene. When the number of carbon atoms is less than 4 or more than 5, the reactivity of the alpha-olefin with the comonomer is low during the production of the random copolymer, making it difficult to produce the copolymer. Further, it may contain 1 to 15% by weight, preferably 1 to 10% by weight, and more preferably 3 to 9% by weight of the above-mentioned alpha olefin. If the amount of the alpha-olefin is less than 1% by weight, the crystallinity becomes higher than necessary and the transparency is lowered. When the amount of the alpha-olefin is more than 15% by weight, the crystallinity and rigidity are lowered and the heat resistance is significantly lowered.

In addition, the ethylene-propylene block copolymer contains 20 to 50% by weight of ethylene and imparts impact resistance to the polypropylene resin composition and enables finely dispersing, thereby imparting both whitening resistance and transparency. The ethylene content may preferably be 20 to 40% by weight, and if it is less than 20% by weight, the impact resistance is deteriorated. If it exceeds 50% by weight, the impact resistance and whitening resistance may be deteriorated.

In addition, a surface protective coating layer containing a silicon component may be formed to solve the surface contamination problem which causes the outage and the life shortening of the smoke cutoff sensor 330 to occur. The surface protective coating layer prevents the adhesion of microorganisms and floating matters, thereby preventing the outdoors and extending the usage period of the heading sensor 103 semi-permanently.

The method of preparing the surface protective coating layer will be briefly described. First, the dimethyldichlorosilane solution is dissolved in ethyl acetate at a volume ratio of 2-5% to prepare a coating liquid. At this time, if the content of the dimethyldichlorosilane solution is less than 2%, the coating effect can not be sufficiently obtained. If the content exceeds 5%, the surface protective coating layer becomes too thick and the efficiency becomes poor.

The solution of the surface protective coating layer dissolved in the above ratio preferably has a viscosity of 0.8-2 cp (centipoise) in consideration of the application time and the coating thickness. This is because if the viscosity is too low, the application time must be long, and if the viscosity is too high, the application may become thick and dry, and non-uniform application may cause the sensor to come out.

In the present invention, the surface of the smoke cut-off sensor 330 is coated with the coating solution prepared as described above to a thickness of 1 μm or less. At this time, if the thickness of the surface protective coating layer exceeds 1 탆, the sensitivity of the sensor is lowered. Therefore, in the present invention, the thickness of the surface protective coating layer is limited to 1 탆 or less. In addition, as the method of applying the thickness as described above, a spray method of spraying the surface of the smoke cutoff sensor 330 about 2-3 times may be used.

To the terminal 251 of the synthetic resin material forming the body of the terminal 251, a polymerized trimethyl dihydroquinoline (RD) may be added to increase the oxidation resistance. This RD increases ozone resistance and oxidation resistance and prevents corrosion and oxidation of the terminal 251 body.

The present invention preferably includes 0.4 to 1.2 parts by weight of RD relative to 100 parts by weight of the synthetic resin material constituting the terminal 251 body. This is because if the addition amount of RD is less than the above-mentioned range, it is difficult to obtain oxidation resistance, and if it exceeds the above-mentioned range, the density and firmness of the tissue are affected.

Since RD is further added to the body of the terminal 251 of the synthetic resin material, the oxidation resistance of the present invention is greatly improved, thereby maximizing the service life of the product.

In addition, a coating composition for preventing corrosion can be applied around the housing 210.

The coating composition was prepared by mixing 100% by weight of a water-soluble resin composition prepared by mixing 80% by weight of resorcinol diglycidyl ether and 20% by weight of propanol amine, 1 to 10% by weight of hexamethylated-hexamethylol melamine.

In the present invention, corrosion resistance of the environmentally friendly housing 210 is improved by utilizing characteristics such as excellent chemical resistance and dimensional stability of resorcinol diglycidyl ether, properties such as corrosion resistance of propanolamine, and excellent lubrication characteristics of melamine derivatives. It is possible to form a coating for prevention.

The method for applying the coating composition for preventing corrosion is not particularly limited, but it is preferable that the coating composition is applied to the surface of the housing 210 so that the dry film thickness is 10 to 30 占 퐉. If the dry film thickness is less than 10 탆, the service life can be shortened, and if it exceeds 30 탆, there is no problem in function but the economic advantage is reduced.

In addition, the housing 210 coated with the coating composition for preventing corrosion is cured by air drying for 10 to 30 minutes and then at 100 to 200 ° C, preferably 150 to 180 ° C for 10 to 50 minutes to obtain a non- . ≪ / RTI >

As the lid 240 is coated with a perfume material having sterilizing function around the periphery of the lid 240, the lid 240 can be kept clean.

The functional oil may be mixed with 95 to 97% by weight of a perfume and 3 to 5% by weight of a functional oil. The functional oil may include 50% by weight of myrtle oil, And 50% by weight of a cube oil (Litsea cubeba oil).

Here, the functional oil is preferably mixed with 3 to 5% by weight based on the perfume. If the mixing ratio of the functional oil is less than 3% by weight, the effect is insignificant. If the mixing ratio of the functional oil exceeds 3 to 5% by weight, the function is not greatly improved, but the manufacturing cost is greatly increased.

The major chemical components of myrtle oil are cineol and myrtenol. It is extracted by steam distillation method in sprout and small branches. It is yellowish and has a refreshing and refreshing aroma. It has good effect on sterilization and side effects.

Litsea cubeba oil extracts oil from fruit using steam distillation method. It is sweet but similar to lemon grass. It has a strong aroma. It contains citral which is more than 85% as main chemical ingredient, linalol, neral, etc. It has a strong antiseptic effect, and it has excellent action effect of killing bacteria and the like by bactericidal action.

As the functional oil is coated around the lid 240, the lid 240 is sterilized, thereby improving the health of the user.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the same is by way of illustration and example only and is not to be construed as limiting the present invention. It is obvious that the modification or improvement is possible.

It is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
