Description
Technical field
The present invention relates to a kind of domestic gas alarm, also relate to a kind of method that is used to demarcate the domestic gas alarm.
Background technology
Common combustion gas comprises liquefied petroleum gas (LPG), artificial coal gas and rock gas, and there is very big potential safety hazard in the leakage of combustion gas; Crisis people's safety and Health and property are when especially using in the kitchen, house, because the fatigue that is busy with one's work; The leakage of combustion gas many times is ignorant, has very big hidden danger, for this reason; Gas alarm has appearred on the market; Specially gas leakage in the family is detected and give alarm and reminding, avoid unnecessary accident to take place, bring huge property loss and casualties.
But existing gas alarm is generally all at a corner design air chamber; Head with smoke transducer is placed on wherein again, detects airborne gas concentration, if the concentration of gas is higher than certain settings; Will send warning automatically, to remind the people of family.
But, air chamber is arranged on the corner of alarm, cause gas flow property poor, if oil smoke gets into, oil smoke is just stained the surface of sensor easily, reduces the sensitivity of sensor, does not have the due warning effect of alarm.
In gas alarm, sensor is its main element, so sensor that the position is set is particularly important, this can influence the accuracy of gas detection and sensitivity, is related in time to remind the household.But existing domestic gas alarm and since sensor that the position is set is not good, cause the concentration of detected gas in time, have great potential safety hazard, be unfavorable for long-run development.
Also have, each sensor performance index is all different, demarcates so gas alarm all will carry out alarming value before dispatching from the factory, and what have in use also needs periodic calibrating.
In the traditional design, mainly contain dual mode:
Complete machine is demarcated, and this mainly is a manual detection, changes the resistance that is complementary after the calculating, but such demarcation mode, accuracy is very poor, makes mistakes easily, simultaneously, and single test, efficient is low, and speed is slow.
Transducer calibration, this mode mainly are that sensor is demarcated, and then the alarm of packing into, the corresponding resistance of burn-oning; But this mode is at timing signal, because do not pack housing in advance into; Variant with the reality use, and when welding, corresponding in groups; The artificial mistake of welding easily causes unnecessary loss, is unfavorable for long-run development.
This shows that these problems have much room for improvement.
Summary of the invention
The object of the present invention is to provide a kind of domestic gas alarm, exquisiteness simple in structure, the gas stream general character is good; Can detect in time and report to the police, improve the accuracy that detects simultaneously greatly, can realize simultaneously demarcating automatically; Speed is fast, and accuracy is high, reduces manual work greatly and goes out rate.
To achieve these goals, technical scheme of the present invention is following:
The domestic gas alarm is characterized in that: comprising:
Housing, said housing comprises upper shell and lower house; Said lower house is provided with baffle plate; Form open channels between this baffle plate and bottom, the sidewall, when lower house and upper shell lump together, form non-opened type air chamber between said open channels and the upper shell; This air chamber is the L type, comprises first air chamber and second air chamber;
Be provided with detection architecture in enclosure interior, said detection architecture comprises controller, processing enter and sensor, and said processing enter comprises single-chip microcomputer and 4 resistance;
Also be provided with alarm.
By on can know that the present invention is arranged to the L type with its air chamber, that is to say the setting of second air chamber; Be beneficial to gas is extracted out, increased the flowability of gas in air chamber, after oil smoke gets into air chamber, attached to the right side of first air chamber; Gas gets into the left side, is flowed out by second air chamber, reduces the pollution of oil smoke.
Further, all be provided with a plurality of air admission holes that are set up in parallel on the bottom of said first air chamber and the sidewall;
The setting of this structure is unobstructed for the entering that improves gas, if air admission hole is perhaps not enough less, the amount that will cause gas to get into is few, causes detection alarm not prompt enough, has potential safety hazard.For this reason, air inlet structure is arranged on a plurality of air admission holes that are set up in parallel, can improves the inlet of gas greatly, guarantee that detection alarm is timely.
Further, the sidewall of said second air chamber and top all are provided with a plurality of ventholes that are set up in parallel;
The setting of this structure is in order to improve the outflow of gas, to increase gas flow property; Comprise that wherein oil smoke or other foreign gases remain in the air chamber, cause detecting inaccurate, for this reason; This structure increases gas flow property, guarantees the accuracy of gas detection.
Further, said first air chamber is near forming a breach with the second air chamber crossing;
Further, said sensor is arranged on indentation, there.
The setting of this structure, the detection that can greatly improve sensor, because the indentation, there of first air chamber is near the turning, its circulation is good; Improve the sensitivity that detects greatly,, just be difficult to be detected, simultaneously if the circulation in the air chamber is bad; Gas is residual easily, causes flase drop, another side, and gas can not in time circulate into; Will cause detecting not prompt enough, the delay time at stop, have potential safety hazard.
So above-mentioned setting can detect and report to the police in time, improve the accuracy that detects simultaneously greatly, be beneficial to long-run development.
Two of the object of the invention is to be to provide a kind of method that is used to demarcate the domestic gas alarm, it is characterized in that: may further comprise the steps:
The first step adds alarm gas at the family expenses gas alarm;
In second step, open computing machine, and send the demarcation instruction by computing machine;
In the 3rd step, single-chip microcomputer is adjusted resistance value automatically, and resistance value is deposited in the single-chip microcomputer after receiving and demarcating instruction;
The 4th step progressively added the concentration that increases alarm gas, repeated three steps of the first step to the successively;
The 5th step, after accomplishing, assembling starts shooting, will call in the resistance value of coupling automatically.
In actual use, add alarm gas in the alarm, send by computing machine and demarcate instruction; After single-chip microcomputer in the alarm receives order; Automatically adjust the resistance value that is complementary with inductor, wherein 4 resistance can mix 15 different resistance values automatically, for this reason; The setting of 4 resistance can improve usable range.After automatic adjustment resistance value, and this numerical value deposited in the single-chip microcomputer automatically, wait start next time after, single-chip microcomputer will be called in the resistance value that is complementary automatically, this mode efficient is high, speed is fast, reduces manually-operated efficient greatly.
Beneficial effect of the present invention: the present invention's exquisiteness simple in structure, the gas stream general character is good, can detect in time and report to the police, and improves the accuracy that detects simultaneously greatly, can realize simultaneously demarcating automatically, and speed is fast, and accuracy is high, reduces manual work greatly and goes out rate.
In order further to explain technical scheme of the present invention, come the present invention is set forth in detail through specific embodiment below.
