Description
Technical field
The present invention relates to a kind of gas sensor, especially a kind of active gas sensor.
Background technology
Formaldehyde in indoor air, VOC, etc. harmful object have a strong impact on the health of people.People sense usually through air body
Device or air purifier carry out the pernicious gases such as detection formaldehyde.The gas sensor such as formaldehyde on the market is passive at present
Formula, only when in air be harmful to or toxic gas it is exceeded, be all to diffuse in rear passive entry sensor, sensor just start detect
With alarm, but air ambient is given in this case, or even personal safety brings serious harm.If poisonous or asphyxiating
Gas, has generated the situation that can not be retrieved, such as gas leak, gas.
In addition, existing sensor is expensive, especially electrochemical sensor, the gas with certain electrochemical material
Sensor constantly consumes its internal material, therefore use because internal material will be implemented and detect that gas chemically reacts
Restricted lifetime, because of electrochemical material reduction or totally after long-time use, sensor failure.Gas sensor on the market is big
Structure more without replaceable material can not be reused, and also and then failure wastes larger to shell of sensor etc..Other air
In adrift the material such as dust influence the accuracy of detection of sensor, therefore high-performance sensors are with greater need for replaceable filtering
Net device, the work permanently effective to ensure sensor response storehouse is harmful to or toxic gas in gas sensor detection in addition
While, these gases cause the change of environment temperature also very big, such as after Liquified gas leakage, the temperature meeting step-down of surrounding, this
A little conventional designer often ignores, and causing the unstability of sensor signal source feedback parameter increases.
The content of the invention
In order to which the real-time for overcoming the shortcomings of existing air borne sensor is poor, service life is shorter, the invention provides one
Plant the active gas sensor that real-time is preferable, service life is longer.
The technical solution adopted for the present invention to solve the technical problems is：
Reaction warehouse for realizing air detection is installed in a kind of active gas sensor, including shell, the shell,
It is characterized in that：The shell is provided with installation axle stream in air inlet, detection gas passage and gas outlet, the detection gas passage
Blower fan, the axial flow blower is located in shell, and the reaction warehouse is set between the import of the air inlet and axial flow blower, described
The outlet of axial flow blower is connected with the gas outlet.
Further, the mounting groove for the reaction warehouse detachable grafting is provided with the shell, the reaction warehouse is plugged on
In the mounting groove.
Further, screen pack is set between the air inlet and reaction warehouse.
The screen pack is detachable to be plugged in the neck of the shell.
Further, mounting temperature sensor in the shell, the signal of the temperature sensor and the reaction warehouse is defeated
Go out end to be connected with intellectual checkout and control device.The Current Temperatures detected by temperature sensor and the temperature of detection demarcation are compared
Compared with realizing temperature-compensating so that air concentration detection is more accurate.
Humidity sensor is installed, the signal output part of the humidity sensor and the reaction warehouse is and intelligence in the shell
It can detect that controller is connected.The current humidity detected by humidity sensor and the humidity of detection demarcation are compared, and are realized wet
Degree compensation so that air concentration detection is more accurate.
Beneficial effects of the present invention are mainly manifested in：Real-time is preferable, service life is longer.
Brief description of the drawings
Fig. 1 is the schematic diagram of active gas sensor.
Fig. 2 is the decomposing schematic representation of active gas sensor.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Referring to Figures 1 and 2, installed in a kind of active gas sensor, including shell 1, the shell 1 for realizing sky
The reaction warehouse 2 of gas detection, the shell 1 is described to detect in gas passage provided with air inlet 3, detection gas passage and gas outlet 4
Axial flow blower 5 is installed, the axial flow blower 5 is located in shell 1, and institute is set between the import of the air inlet 3 and axial flow blower 5
Reaction warehouse 2 is stated, the outlet of the axial flow blower 5 is connected with the gas outlet 4.
Further, the mounting groove for the reaction warehouse detachable grafting, the grafting of reaction warehouse 2 are provided with the shell 1
In the mounting groove.
Further, screen pack 6 is set between the air inlet 3 and reaction warehouse 2.
The screen pack 6 is detachable to be plugged in the neck of the shell.
Further, mounting temperature sensor in the shell 1, the signal of the temperature sensor and the reaction warehouse is defeated
Go out end to be connected with intellectual checkout and control device.The Current Temperatures detected by temperature sensor and the temperature of detection demarcation are compared
Compared with realizing temperature-compensating so that air concentration detection is more accurate.
Humidity sensor is installed in the shell 1, the signal output part of the humidity sensor and the reaction warehouse with
Intellectual checkout and control device is connected.The current humidity detected by humidity sensor and the humidity of detection demarcation are compared, and are realized
Humidity is compensated so that air concentration detection is more accurate.
In the present embodiment, axial flow blower drives fan blade mechanical operating in air channel, draws air into reaction warehouse, together
When the air that sucks first pass around filter, filter can be dismantled, and cleaned and changed.The air sucked by fan blade will be through
Taken in reaction warehouse and tested and analyzed by power after filtering dust, while the technique, this reaction warehouse such as being electrochemically reacted
Also there is replaceable structure, the reaction warehouse can be regularly replaced, ensure that detection is harmful with the work for keeping sensor permanently effective
Or the accuracy of toxic gas.Temperature sensor and humidity sensor are also devised with addition, by detecting the temperature under current environment
Degree and humidity, are compared with the factory-designed temperature and humidity of sensor, realize temperature-compensating so that air concentration detects number
According to more accurate.
Furthermore, the volatilization change of exactly poisonous when the temperature increases or pernicious gas more enlivens period.Such as temperature step-down,
It is possible to liquefied gas to reveal, so as to help to analyze the accurate data of detection, and feeds back to signal source in time.
Mechanical structure, the quick reaction warehouse that gas source is sucked to sensor in time are carried out by being designed with impeller of blower
To detect, carrying out mechanical structure without motor fan fan blade in the past quickly cannot timely will be far from the gas of sensor
Source is drawn into reaction warehouse in real time in time, misses the optimal key period to take precautions against and remedying, often influences whether life security,
For example " traffic police investigates and prosecutes drunk driving, must driver firmly gas in mouth be blown into alcohol content tester can just detect whether
It must just start alarm behind the exceeded arrival sensor present position of gas density under drunk driving, mine；There is the progress of motor fan blade
Mechanical structure both of which quickly can be detected timely, realize that prompting user's pernicious gas is exceeded in advance
It is significant.
The use of gas sensor can be greatly improved by being designed with the structure of replaceable filtering dust and replaceable reaction warehouse
In the life-span, the sensor of costliness can be used for a long time, material is saved.
