Description
Technical Field
The utility model relates to a gas valve does not close reminding device's technical field.
Background
Natural gas is used as a clean, pollution-free and high-quality energy, and particularly, in daily life, gas cookers using natural gas are used by households. When the gas valve is convenient to use, the gas valve is forgotten to be closed due to negligence, so that gas leakage is caused, and the case that personnel and property loss is caused is also compared.
At present, in order to reduce and reduce the occurrence of such events, the concentration of natural gas in the air is mostly detected, or some gases with special odor are added into the natural gas, and accidents caused by forgetting to close a gas valve are avoided through concentration detection or olfaction and the like. But concentration detection or olfaction is inaccurate and has a certain hysteresis, especially for the elderly alone at home.
Disclosure of Invention
The utility model aims at providing a simple structure, convenient operation can in time detect the gas valve of gas valve closed state and not close reminding device.
A gas valve non-closing reminding device comprises a valve detection device arranged at a gas valve and a control device arranged at a cooking bench, wherein the valve detection device comprises a mercury switch arranged at a handle of the gas valve, and the mercury switch and a first external circuit form a series circuit through a trigger 1K; the control device comprises a temperature measuring resistor arranged on the lower portion of the cooking bench, the temperature measuring resistor is connected with a main controller through an ADC circuit, and the main controller is connected with a buzzer and a second external circuit respectively.
Preferably, the utility model discloses a wireless transmission between first external circuit, the second external circuit.
Preferably, the second external circuit of the present invention is connected to the LED display device through a trigger.
The utility model adopts the above technical scheme, compare with prior art and have following advantage:
1. the utility model arranges the valve detection device on the handle of the household gas valve, and utilizes the fluidity of mercury in the mercury switch to determine the opening and closing of the valve; the control device measures the working temperature of the cooking bench by using the temperature measuring resistor to determine whether the cooking bench is in a working state or not, and further determines whether the valve of the gas cooker which is not in the working state is in a closed state or not. The use safety is improved, the operation is simple and convenient, the energy consumption is lower, no wire connection is needed, and only dry batteries are needed
2. The utility model discloses a buzzer or LED display module report to the police, remind the user not to close the gas valve through the effect of reputation, are particularly suitable for middle aged and old people to use.
3. The utility model discloses a valve detection device and temperature-detecting device and master control are separately, can not have the criss-cross inconvenient part of wire. The kitchen cabinet is convenient to use, and the kitchen cabinet cannot be messy due to too many wires.
4. The utility model discloses a temperature measuring resistor adopts platinum resistance magnetism to inhale the mode and carries out the temperature measurement more accurate convenient. And the waterproof design is adopted, so that the problem that the temperature measuring resistor is in water inflow when the cooking bench is cleaned is avoided, and the service life is prolonged.

Detailed Description
The technical scheme of the utility model is explained in detail with the attached drawings as follows:
as shown in fig. 1 and 2, a gas valve non-closing reminding device comprises a valve detection device arranged at a gas valve and a control device arranged at a cooking bench, wherein the valve detection device comprises a mercury switch arranged at a handle of the gas valve, and the mercury switch forms a series circuit with a first external circuit through a trigger 1K; the control device comprises a temperature measuring resistor arranged on the lower portion of the cooking bench, the temperature measuring resistor is connected with a main controller through an ADC circuit, and the main controller is connected with a buzzer and a second external circuit respectively.
The utility model discloses a wireless transmission between first external circuit, the second external circuit.
As shown in fig. 2, the second external circuit of the present invention is connected to the LED display device through the trigger.
The utility model discloses the model of first external circuit, second external circuit is JDY-40. The utility model discloses temperature measuring resistor's model is PT 100. The utility model discloses main control unit's model is AT89C52 singlechip.
The utility model discloses a controlling means includes temperature measurement circuit, alarm circuit and main circuit. The control device is separated from the valve detection device, the control device is arranged in a gap below the gas cooker, and the temperature measuring resistor is a PT100 type platinum thermal resistor adopting a waterproof design and is attached to the position right below an outer fire cover of the gas cooker in a magnetic attraction mode for temperature detection.
When the utility model is used, after the gas valve is opened, the mercury switch of the valve detection device is closed, the first external circuit is communicated through the trigger, the first external circuit transmits a signal to the second external circuit, the temperature measuring resistor of the control device starts to work, and when the temperature of the cooking range is detected to be in a temperature rising state and is higher than a set temperature, the main controller judges that the cooking range is in a working state and does not give an alarm; and if the temperature of the cooking range is detected to be continuously lower than the set temperature, the main controller judges that the cooking range is not in the working state, and then the alarm is given through the buzzer and/or the LED display device.
The utility model is suitable for a gas valve in general family, low price, easy and convenient operation, the energy consumption is lower, need not the line, only need the dry battery can. The utility model discloses thereby it uses to be particularly suitable for middle aged and old people, thereby avoided middle aged and old people often can forget the problem that closes the valve and lead to gas leakage. The utility model discloses a valve detection device and controlling means part, in the time of facilitating the use, thereby can not make the kitchen become too in disorder because of the wire is too many. The utility model discloses a temperature measuring resistor adopts platinum resistance magnetism to inhale the mode and carries out the temperature measurement more accurate convenient.
