Description

  The present invention relates to a bad breath check device that checks the degree of bad breath and alcohol using a gas sensor.

  Recently, an increasing number of people are concerned about bad breath, and various bad breath check devices equipped with gas sensors have been proposed. As these breath odor check devices, for example, as shown in Patent Document 1, a sensor is provided in a sensor housing portion having a predetermined space, and breath is blown into the sensor housing portion from the breath blowing port of the sensor housing portion. There is a device that measures bad breath stagnant in the space of the storage unit with a gas sensor.

  Moreover, as shown in Patent Document 2, a gas sensor is provided in a cylindrical case having a predetermined space, a mouthpiece is attached to the tip of the cylindrical case, and the gas sensor is received by holding the mouthpiece at the mouth during measurement. An apparatus has also been proposed in which breathing is blown into a predetermined space and breath breath is measured to measure in a state in which the breath is not leaked to the outside.

  However, since the sensor housing part communicates with the outside air, the one shown in Patent Document 1 is mixed with outside air at the time of measurement. In particular, when the wind hits, the measurement result of bad breath is greatly affected by the outside air. There is a problem that variation occurs, and the exhaled breath may escape to the outside. Therefore, it is necessary to keep blowing exhalation during the measurement, which is inconvenient.

  Moreover, since the thing shown in patent document 2 uses the elongate cylindrical case and mouthpiece, it does not receive the influence of external air like the said patent document 1, and exhalation escapes outside. In order to use the mouthpiece by holding it in the mouth, the mouthpiece must be cleaned every time it is used for hygiene, and because the device is large due to the elongated mouthpiece, etc., it is inconvenient and expiratory. Saliva or the like that comes out when blowing in can easily accumulate in the cylindrical case or the mouthpiece, which causes inaccurate measurement of bad breath.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a bad breath checking apparatus that is easy to use and can be measured accurately.

  According to the first aspect of the present invention, a gas sensor is disposed in a sensor housing portion having a predetermined space and having an exhalation blowing port formed on a wall surface, and breath breath is blown into the space from the exhalation blowing port to measure bad breath. In the breath odor check device, a lid is provided that allows the breath blowing port to be freely opened and closed, and the space of the sensor housing portion is switched between a state communicating with outside air and a state shut off. .

  The invention according to claim 2 is characterized in that the lid of the sensor housing portion is constantly biased in the opening direction.

  According to the configuration of claim 1, after inhaling exhalation into the space of the sensor housing portion with the lid open, the lid is immediately closed to shut off from the outside air, and the bad breath can be measured in that state. It is possible to accurately measure bad breath without being affected by outside air. Further, since there is no need to provide a mouthpiece, the apparatus can be miniaturized, the hygiene is improved, the usability is improved, and there is an effect that the trouble caused by the accumulation of saliva and the like is eliminated.

  According to the configuration of the second aspect, since the space of the sensor storage portion is always kept in communication with the outside air except during the measurement, even if moisture such as saliva is mixed when exhaling, the sensor is evaporated immediately. The storage section can be kept clean.

The perspective view which shows the cover body open state of 1st Example of this invention. Same as above The principal part enlarged front view which shows a cover body obstruction | occlusion state same as the above AA sectional view of FIG. BB sectional view of FIG.

  Embodiments of the present invention will be described below with reference to FIGS. The present embodiment shows an example in which the main body 1 and the sensor storage unit 2 constituting the bad breath measurement unit are integrated as a small portable device, but the present invention is not limited to this, and the two are separated. It may be configured as follows.

  The main body 1 is formed in a cylindrical shape, and a display unit 3 for displaying a breath odor measurement result and a switch 4 for turning on / off the power supply are provided on the surface thereof. Control means (not shown) for calculating and displaying are stored.

  The sensor storage portion 2 is formed in a cylindrical shape, and a gas sensor 5 for measuring bad breath is disposed at the bottom thereof, and a predetermined space 6 for introducing exhalation is formed above the gas sensor 5, and its peripheral wall Is formed with an exhalation inlet 7.

  The exhalation inhalation port 7 is for injecting exhalation into the space 6 of the sensor storage unit 2. The exhalation insufflation port 7 can be freely opened and closed by the lid 8, and the sensor storage unit 2 communicates with outside air It switches to the state which interrupts. For this reason, the lid body 8 can be closed immediately after inhaling the breath to shut off the outside air, and the breath odor can be accurately measured without being influenced by the outside air.

  As shown in FIGS. 4 and 5, the lid 8 is opened and closed by a turning operation of a knob 9 disposed on the upper part of the sensor housing portion 2, and the knob 9 is moved by a spring 10. The cover 8 is always urged in the opening direction. For this reason, since the inside of the sensor storage unit 2 is always kept in communication with the outside air except during measurement, even if moisture such as saliva is mixed when exhalation is blown, the sensor storage unit 2 is immediately evaporated. Can be kept clean.

  Thus, when measuring, as shown in FIG. 2 and FIG. 4, the exhaled breath 7 is opened and the exhaled breath is blown into the space 6 of the sensor housing 2, and then the knob 9 is manually rotated. 3 and FIG. 5, the breath blowing port 7 is closed and the outside air is blocked, and the bad breath is measured. Next, when the hand is released from the knob 9 when the measurement is completed, the exhalation air inlet 7 is automatically opened by the spring 10 as shown in FIGS. 2 and 4, and the space 6 of the sensor housing 2 is opened to the outside air. It is held in communication with.
