Deflation taste, is then responded by sensor, which includes two sets of different refrigeration systems and heating system, and is equipped with big
Quantity sensor.
Additionally, it is well known that the olfactory organ of canine is very flourishing, it is tens or even thousand times of human olfactory.Therefore canine
Sensitive smell can be used for following the trail of assailant, investigate the missing and rescue, early warning etc. of drugs and the natural calamity such as explosive, earthquake
Deng.But canine, which is training the problem of maximum in such application, very needs time and skill.This is because canine is big
Brain is simultaneously undeveloped, only walnut size, in addition also has some setbacks with Human communication.If smell the brain of the mankind and canine are sharp
Feel is combined together, that will be a huge innovation.People can be not required to training and can play canine to apprehend the murderer, and rescue it
In effect, and by means of powerful brain memory, thinking and analysis ability, people can than canine faster, it is more accurate.
The content of the invention
Goal of the invention：The technical problems to be solved by the invention are in view of the deficiencies of the prior art, there is provided one kind can increase
Portable, easy-to-use, the cost-effective device of strong gas concentration, by human olfactory organ directly hear the gas after concentration increase into
The discrimination of promoting the circulation of qi taste.
In order to solve the above-mentioned technical problem, the invention discloses a kind of smell booster based on pre-concentration principle, the dress
Put the sorbing material including two block semiconductor refrigerators and between two block semiconductor refrigerators, the two block semiconductor system
Cooler connects power supply, is cooled down using peltier effect to sorbing material, so as to be adsorbed to smell, then reversal connection power supply
Heat up to sorbing material, so that the high concentration smell of absorption be discharged.
Wherein, the sorbing material is filled in inside absorbent container, and absorbent container has air inlet and gas outlet.
Further, the absorbent container is internally provided with gas channels, its one end connection air inlet, and the other end connects out
Gas port, filling adsorption material in the gas channels, by setting passage, can allow gas in absorbent container internal stops
Between increase, so as to improve adsorption efficiency of the sorbing material to smell.
The absorbent container material is aluminium, its opposite two sides sign chill surface with two block semiconductor refrigerators respectively
Contact, and being smeared using thermal grease makes it combine closely so as to preferably heat conduction.
The circuit that the semiconductor cooler is connected with power supply is equipped with hand-operated valve, and manually valve is vertically connected with, and controls
Semiconductor cooler processed is just connecing and reversal connection power supply.
The air inlet and gas outlet are connected to tracheae, and tracheae is equipped with the micropump of regulating flow quantity, passes through micropump
The gas adsorbed in advance is pumped into absorbent container with 4~6L/min and is adsorbed, then adjusts miniature pump discharge by adsorbent
The gas that smell has been adsorbed in container is exported with 0.3~0.5L/min.
The two block semiconductors refrigerator is respectively connected with radiator backwards to the one side of sorbing material, and radiator carries radiation air
Fan.
The sorbing material is one or more in activated carbon, activated alumina, silica gel or zeolite molecular sieve
Combination, preferably activated carbon.
The present invention cools down sorbing material and is risen by the positive-negative connected of positive and negative anodes using semiconductor cooler to realize
Temperature, sorbing material absorption smell and is concentrated during low temperature, is then again discharged high concentrations of gas by elevated temperature desorption, so as to lead to
High concentration smell can be distinguished by crossing smell, and selected radiator is the common radiator of computer, and absorbent container is also selected from computer
Water-filled radiator.The device volume is small, and price is low, and effect is good, is adapted to daily life and personal use.
Beneficial effect：
1st, the present apparatus cooled down using semiconductor cooler by the positive-negative connected of positive and negative anodes to sorbing material realizing and
Heating, without being equipped with other heating and cooling system, so that it may realize the collection concentration of smell.
2nd, present apparatus charge flow rate is much larger than out throughput, can ensure the adsorption efficiency of smell, while meets to identify gas
The time of taste and concentration need.
Brief description of the drawings
