Abstract
The invention provides a smell sensor device for a refrigerator. The smell sensor device is characterized in that a smell sensor array is positioned on a shell; the back side of the smell sensor array is connected with a processing module; the processing module is connected with a micro fan, a power interface and a signal interface; the micro fan is positioned on the shell, and directly faces the smell sensor array. The smell sensor device comprises a lithium battery and a display screen, wherein the lithium battery is positioned in the shell, and is connected with the power interface; the display screen is positioned outside the shell and is connected with the signal interface; the shell is provided with a fixing claw. The smell sensor device has the beneficial effects that the smell sensor array can be used for recognizing smell in the refrigerator to judge whether foods deteriorate or not; the micro fan can be used for driving gas in the refrigerator to flow, so that detection of smell emitted by deteriorated foods is facilitated. The smell sensor device can be used separately or in a way of being attached to a refrigerator component, and is convenient to use.
Description
Technical field
The invention belongs to sensor field, more particularly, to a kind of smell sensor device for refrigerator.
Background technology
Smell sensor is mainly made up of gas sensor array, Signal Pretreatment and pattern recognition three part.Certain gas
Before taste is presented on a kind of sensor cover of active material, chemistry input is converted into the signal of telecommunication by sensor, by multiple sensors pair
A kind of response of abnormal smells from the patient just constitutes the response spectra to this abnormal smells from the patient for the sensor array.Obviously, the various chemical compositions in abnormal smells from the patient are equal
Can have an effect with sensitive material, so this response spectra is the broad spectrum response spectrum of this abnormal smells from the patient.For realizing to the qualitative of abnormal smells from the patient or
Quantitative analyses are it is necessary to carry out adopting the signal of sensor after suitable pretreatment (eliminating noise, feature extraction, signal amplification etc.)
With suitable pattern recognition analysis method, it is processed.In theory, every kind of abnormal smells from the patient all can have its characteristic response to compose, according to
Its characteristic response spectrum can distinguish little same abnormal smells from the patient.The intersection being simultaneously also with gas sensor forming array to multiple gases is quick
Perception measures, and by suitable analysis method, realizes analysing mixed.
With the quickening of people's rhythm of life, a lot of families have formed the weekend central merchandising food storing of a week in refrigerator
Custom.But refrigerator is an instrument delaying food spoilage, and due to depositing, food is more, the situation of food spoilage
Exist with the prolongation of storage period, and user is difficult to find in time the putrid and deteriorated of food.Distribute after meat, fruit and vegerable iso-metamorphism
The abnormal smells from the patient going out is different, and what group food existing refrigerator cannot provide rotten prompting for user.
Content of the invention
In order to solve above-mentioned technical problem, the present invention provides a kind of smell sensor device for refrigerator, and its feature exists
In inclusion housing, processing module, smell sensors array, mini-fan, power interface and signaling interface, described smell sensor
Array is located on described housing, and its back side is connected with described processing module, and described processing module is connect with described mini-fan, power supply
Mouth and signaling interface connect, and described mini-fan is located on described housing, and just to described smell sensors array.
Also include lithium battery and display screen, described lithium battery is located in described housing, and is connected with described power interface, institute
State display location in described hull outside, and be connected with described signaling interface, described housing is provided with fixed claw.
Described processing module includes pattern recognition module, signal pre-processing module, power module and display control module.
The invention has the benefit that using smell sensors array, being capable of identify that the abnormal smells from the patient in refrigerator, judging that food is
No rotten；Gas flowing can be made in refrigerator using mini-fan, beneficial to detecting the abnormal smells from the patient giving out after food spoilage.This abnormal smells from the patient
Sensor device can individually or depend on refrigerator part use, easy to use.
Brief description
Fig. 1 is the structural representation of the present invention.
Specific embodiment
Below with reference to accompanying drawings the present invention is described in more detail, which show the preferred embodiments of the present invention,
It should be appreciated that those skilled in the art can change invention described herein and still realize the advantageous effects of the present invention.Cause
This, description below is appreciated that widely known for those skilled in the art, and is not intended as limitation of the present invention.
In figure, 1, housing；2nd, processing module；3rd, smell sensors array；4th, mini-fan；5th, power interface；6th, signal
Interface；7th, lithium battery；8th, display screen.
As shown in figure 1, described smell sensors array 3 is located on described housing 1, its back side is with described processing module 2 even
Connect, processing module 2 is located inside housing 1, described processing module 2 is with described mini-fan 4, power interface 5 and signaling interface 6 even
Connect, described mini-fan 4 is located on described housing 1, and just to described smell sensors array 3.Described smell sensors array 3
Using conductive polymer sensors, the range of sensitivity is 10～100ppm.During use, the present invention is arranged on the cold room of refrigerator
Interior, power interface 5 is connected with the power line of refrigerator, and signaling interface 6 is connected with the display screen of refrigerator.
The present invention also can independently use.Described lithium battery 7 is located in described housing 1, and is connected with described power interface 5,
Described display screen 8 is located at outside described housing 1, and is connected with described signaling interface 6, and described housing 1 is provided with fixed claw.Use
When, the cold preservation that the present invention is fixed on refrigerator by fixed claw is indoor
Described processing module 2 includes pattern recognition module, signal pre-processing module, power module and display control module.
Above by embodiment, the present invention is described in detail, but described content has been only the preferable enforcement of the present invention
Example is it is impossible to be considered the practical range for limiting the present invention.All impartial changes made according to the present patent application scope and improvement
Deng all should still belong within the patent covering scope of the present invention.
