A kind of Low Power Consumption Portable pneumostome gaseity prompt instrument, comprises implication condition prompting instrument shell, is provided with gas production mouth, is built-in with implication detecting sensor at described gas production mouth in one end of implication condition prompting instrument shell; Single chip microcontroller and power supply is also provided with in implication condition prompting instrument shell, described implication detecting sensor is connected with single chip microcontroller signal, described implication condition prompting instrument shell is provided with the implication display device that can show implication status signal, and the signal transmission of single chip microcontroller is to implication display device; Described power supply is implication detecting sensor, single chip microcontroller and implication display device are powered.
Described implication display device comprises three LED: bright green LED, yellow LED lamp and red LED lamp, respectively pure and fresh, the implication of representative tone can accept and implication dirty.
Described implication detecting sensor is TGS2450 gas sensor.
Described power supply is connected in series by two pieces of 1.5V button cell CR2302 and forms, and it exports as 3V direct current.
Described single chip microcontroller adopts MSP430f169 mixture control.
Described implication display device also comprises acoustical generator, and described LED and acoustical generator control by single chip microcontroller.
Further, implication condition prompting instrument shell is also provided with display instrument whether pilot lamp in working order.
The course of work of the present utility model is: after starting power supply, detected person, within gas production mouth 5 cm distance apart from portable pneumostome gaseity prompt instrument, exhales facing to gas production mouth.Single chip microcontroller is according to sampled result, after relevant information is processed, implication is divided pure and fresh, can accept and dirt totally three kinds of states, the form of result acousto-optic is showed in the LED of implication condition prompting instrument shell and acoustical generator, its by light green LED make simultaneously generator every 1 second send a long and make it continue represent breath freshening, yellow led represents that implication can accept generator and sends a long every 0.4 second and make it to send rapid interrupted tone in lasting 0.4 second, the dirty synchronizer of the bright expression implication of red LED sends free of discontinuities long.Detected person can do corresponding process according to the oral status of testing result to oneself.Each result exports maintenance 8 second above, and system returns again state to be detected afterwards.System has reset function also can make system get back to state to be detected at any time.
The utility model has simple for structure, that cost is low, lightweight, power consumption is little advantage, the state unclean to implication in daily life can detect in time and point out.

Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
A kind of Low Power Consumption Portable pneumostome gaseity prompt instrument, comprises implication condition prompting instrument shell, is provided with gas production mouth 1, is built-in with implication detecting sensor at described gas production mouth 1 in one end of implication condition prompting instrument shell; Single chip microcontroller and power supply is also provided with in implication condition prompting instrument shell, described implication detecting sensor is connected with single chip microcontroller signal, described implication condition prompting instrument shell is provided with the implication display device that can show implication status signal, and the signal transmission of single chip microcontroller is to implication display device; Described power supply is implication detecting sensor, single chip microcontroller and implication display device are powered.Described implication display device comprises three LED: bright green LED 2, yellow LED lamp 3 and red LED lamp 4, respectively pure and fresh, the implication of representative tone can accept and implication dirty.Described implication detecting sensor is TGS2450 gas sensor.Described power supply is connected in series by two pieces of 1.5V button cell CR2302 and forms, and it exports as 3V direct current.Described single chip microcontroller adopts MSP430f169 mixture control.Described implication display device also comprises acoustical generator, and described LED and acoustical generator control by single chip microcontroller.Implication condition prompting instrument shell is also provided with display instrument whether pilot lamp 5 in working order.
Wherein, implication detecting sensor uses TGS2450 gas sensor to detect implication, and sensor external applies to maintain its pulse voltage normally worked, and implication concentration is outputted to single chip microcontroller in the mode of voltage by sensor.Single chip microcontroller is sampled to implication concentration, and after processing data, by result by the LED of implication display device and acoustical generator by the state representation of implication out.
Power supply uses two pieces of 1.5V button cell CR2302 to be connected in series composition, and it exports 3V direct current.
Implication detecting sensor adopts TGS2450 gas sensor.This kind of sensor has high sensitive to sulfur compound class gas, and sulfur compound class gas is then the one of the main reasons causing oral cavity to produce abnormal taste.The induced electricity resistance of TGS2450 blurts out gas concentration according to the change of certain consistent relationship, therefore can by detecting that its resistance value detects the concentration of implication.
