Description
The utility model relates to a kind of safety guard that is used in the family room, particularly a kind of indoor anoxia protection arrangement.
At present, along with the penetration and promotion of household gas apparatus (as water heater, warmer etc.), being everlasting the phenomenon of indoor oxygen deficiency occurs when using, and the person casualty accident of suffocating can take place when serious, and it is more and more outstanding that safety problem has seemed.For addressing this problem, existing at present electromechanical anoxia protection arrangement comes into operation.It mainly is made up of base plate, nozzle, induction tunnel, ignitor, pressing plate and thermocouple, it is placed in the household gas apparatus, the air inlet pipe of its nozzle is communicated with the source of the gas of household gas apparatus by control valve, during use, survey by nozzle by thermocouple and to deliver to induction tunnel and burned flame, when anoxic, the flame of induction tunnel can leave, the temperature of thermocouple head is descended, thereby close source of the gas by control valve.But because it is to respond to ignition temperature by thermocouple, then its sensitivity is low, and reaction speed is slow.
The purpose of this utility model is exactly in order to address the above problem, and provides a kind of highly sensitive, the light-operated anoxia protection arrangement that reaction speed is fast.
Technical solution of the present utility model:
A kind of light-operated anoxia protection arrangement; it includes base plate; pressing plate; ignitor; induction tunnel and nozzle; ignitor is connected on the base plate by pressing plate; induction tunnel also links to each other with base plate; its rear end links to each other with jet expansion; the air inlet pipe of nozzle is communicated with the source of the gas of household gas apparatus by control valve; the spark discharge mouth of ignitor is positioned at the front end exit place of induction tunnel; the position that it is characterized in that the corresponding induction tunnel front end exit in the base plate bottom is provided with infrared probe or light sensor; correspondingly; be connected with in the position of the corresponding induction tunnel front end exit in base plate top and prevent that infrared probe or light sensor from receiving the light barrier of light beyond the flame or thermal signal, the output of infrared probe or light sensor is drawn by lead and is connect peripheral control unit.
A kind of light-operated anoxia protection arrangement; it includes base plate; pressing plate; ignitor; induction tunnel and nozzle; ignitor is connected on the base plate by pressing plate; induction tunnel also links to each other with base plate; its rear end links to each other with jet expansion; the air inlet pipe of nozzle is communicated with the source of the gas of household gas apparatus by control valve; the spark discharge mouth of ignitor is positioned at the front end exit place of induction tunnel; the position that it is characterized in that the corresponding induction tunnel front end exit in the base plate bottom upwards is connected with the metallic rod of two its tops near the induction tunnel flame export; and leave a determining deviation between two metallic rod, two metallic rod are drawn by lead and are connect peripheral control unit.
The utility model adopts light-dependent control element to respond to ignition temperature, and it is highly sensitive, is swift in response, and the automaticity height is manipulated very convenient.The utility model contains the function of lighting main burner, in the burner that uses combustion gas, when indoor oxygen content is lower than normal human needs when using, combustion parts and light-operated part are reacted rapidly in this system, burner in main burner and the utility model is extinguished rapidly, thereby reach the purpose of safe handling.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is another structural representation of the present utility model.
As Fig. 1, the utility model includes base plate 1, pressing plate 2, ignitor 3, induction tunnel 4 and nozzle 5, ignitor 3 is connected on the base plate 1 by pressing plate 2, induction tunnel 4 also links to each other with base plate 1, its rear end links to each other with nozzle 5 outlets, the air inlet pipe of nozzle 5 is communicated with the source of the gas of household gas apparatus by control valve, the spark discharge mouth of ignitor 3 is positioned at the front end exit place of induction tunnel 4, characteristics of the present utility model are, the position of corresponding induction tunnel 4 front end exit is provided with infrared probe or light sensor 6 (as the cadmium sulfide light sensor) in base plate 1 bottom, correspondingly, be connected with in the position of corresponding induction tunnel 4 front end exit in base plate 1 top and prevent that infrared probe or light sensor 6 from receiving the light barrier 7 of light beyond the flames or thermal signal, the output of infrared probe or light sensor 6 is drawn by lead and is connect peripheral control unit.
Like this, when sending electric spark, ignitor 3 ignites after the combustion gas of coming out through nozzle 5 and induction tunnel 4 (they form burner of the present utility model), infrared probe or light sensor 6 just can be sensed this flare up fire, and become the signal of telecommunication and deliver to peripheral control unit (it is for prior art, the signal of telecommunication that its receives can be directly or is controlled the air valve of combustion gas tool source of the gas by drive circuit), when induction tunnel 4 front end exit normal combustion, the air valve of external controller control fuel gas source is outer in normal opening.When because anoxic or burn when undesired, the flame of induction tunnel 4 outlets can leave or extinguish, at this moment, infrared probe or light sensor 6 are guaranteed the safe handling of combustion gas tool with regard to not making peripheral control unit cut off the air valve of fuel gas source rapidly because of receiving light or thermal signal.In the utility model, because light barrier 7 can effectively block light or the heat that the utility model burner sends, so can improve functional reliability of the present utility model and sensitivity greatly.
Perhaps, as shown in Figure 2, the utility model also can upwards be connected with the metallic rod 8 of two its tops near the induction tunnel flame export in the position of base plate 1 bottom correspondence induction tunnel 4 front end exit, and leave a determining deviation between two metallic rod 8, be generally 3-6mm, two metallic rod 8 are also drawn by lead and are connect peripheral control unit.Like this, can save light barrier 7.When sending electric spark, ignitor 3 ignites after the combustion gas of coming out through nozzle 5 and induction tunnel 4, two metallic rod 8 are among the flame of lighting, because flame can make air produce ionization under high-temperature condition, resistance between two metallic rod 8 is reduced rapidly, thereby (it is prior art to make two metallic rod, 8 external controllers, the signal of telecommunication that its produces can be directly or is controlled the air valve of source of the gas by drive circuit) connection work, when drawing barrel 4 front end exit normal combustion, the air valve of external controller control combustion gas tool source of the gas is in normal opening.When because anoxic or burn when undesired, the flame of induction tunnel 4 outlets can leave or extinguish, at this moment, ionosphere between two metallic rod 8 does not exist, so the resistance between them increases rapidly, make external controller cut off the source of the gas of combustion gas tool, guarantee the safe handling of combustion gas tool.
