るといわれている。Air ions move under the influence of an electric field due to their electrical properties, and the moving speed thereof is proportional to the strength of the electric field. The moving speed per unit electric field (1 V / m) is the mobility. Say. This mobility is determined by the ratio of the amount of electricity and the mass of air ions, and those with high mobility are called small ions and those with low mobility are called large ions. Small ions, which are said to have a good effect on living organisms, are those in which gas molecules (such as oxygen molecules) are charged, and their mobility is generally 0.4.
It is said that there is a range of up to 4 cm 2 / V · sec, and large ions are small ions and electrons adhering to dust, dust, fine particles, etc., and their mobility is 0.0005 to 0.01.

The figure shows a configuration in which the power supply circuit of other members such as the blower member and the display member and the ground are independent. That is, the external power source such as the AC adapter supplied to the air ion measuring instrument 1 is not shared as it is with the entire apparatus,
The regulator power supply for the ion detector and the other regulator power supply are completely separated from each other, including the ground. The power supply for the detector is used only for the repulsion electrode plate and the measurement / calculation means, and the other power supplies are the ventilation member, the display device,
It is used for driving a CPU, a control circuit, and the like. By separating the power supply in this way, in the ion detection unit that detects a minute voltage change, accurate ion detection can be performed under a stable power supply without being affected by voltage fluctuations and noise caused by driving the ventilation member.

めることとしてもよいものである。FIG. 5 shows a state in which an air rectifying plate 14 composed of a plurality of plate bodies arranged in parallel is arranged inside the air suction port 10 of the air ion measuring instrument 1 at regular intervals. This is because in order to reduce variations in ion measurement and perform stable ion measurement, it is necessary for the air to flow in the air introducing pipe 8 without being disturbed, and for that purpose, in the present embodiment, a constant interval is required. A straightening vane 14 for laminarizing the air is provided by a plurality of plate members. As a method of stabilizing the flow of air other than using this rectifying plate, it has been conventionally performed to lengthen the gap from the air suction port to the ion detection part, but although there is a rectifying effect, the air introduction tube There is a problem in that the device becomes large and the device becomes large. The current plate 14 of the present embodiment can be downsized by shortening the air introduction pipe. Further, as shown in FIG. 6, by providing the air suction port 10 with the detachable tubular member 15, the distance between the air suction port 10 and each of the ion detection units 4 and 7 is increased, and the air ion measuring device is carried. The air rectifying effect may be further enhanced without impairing the property.

In the air ion measuring device 1, although not particularly shown, its constituent members are made of a synthetic resin material made of an antistatic material or a synthetic resin material using an antistatic paint. Originally, in order to prevent static electricity, it is preferable that the constituent members of the device are made of a conductive metal, but from the viewpoint of design and cost, it is required to use a synthetic resin material.

ものである。FIG. 7 shows a voltage change at the time of ion detection in the measurement calculation means 12 of the air ion measuring instrument 1. That is, the voltage change as the measurement system in the state where air ions are not detected becomes the value of (a) after the static elimination, and the voltage changes as shown in (b) when the air ions are detected. Therefore, usually, the air ion amount is converted by subtracting the voltage value (a) (set to a constant value) from the voltage value (b). However, it was confirmed that the voltage value of (c) after static elimination was not always constant. This is considered to be due to the temperature inside the device, the state of the power supply, noise, etc., and it is very difficult to make the voltage value of (c) constant. Therefore, instead of assuming that the voltage value in (c) is constant, the reference voltage for measurement is set at the end of static elimination (T0),
It is subtracted from the detection voltage after the elapse of the measurement time (T1), and the program of the measurement calculation means 12 is set so that the detection voltage (d) = the voltage after the elapse of the measurement time (T1) -the voltage after the end of the charge removal (T0) It is a thing.

However, the present invention is not limited to this, and it is also possible to provide a plus arithmetic processing unit and a minus arithmetic processing unit.
