As shown, it is possible to check the injection liquid (indicated by the red part) that forms like dew from the inlet part instead of facing forward, or falls downward.

The reason why the chemical is not sprayed in the user's desired position and direction, but is dropped, is because the operation of the blower that advances the chemical forward and the pump that supplies the chemical proceed at the same time.

That is, the chemical liquid is supplied through the injection nozzle by the operation button, and the pressure of the blower for spraying the chemical liquid is not amplified as much as the user wants, and the chemical liquid is not concentrated on the injection nozzle or is not sprayed, but falls downward. .

In addition, this phenomenon also appears in the case of stopping the operation of the quarantine device.

That is, when the operation button is pressed again to stop the operation of the quarantine device, the signal is transmitted to the blower and the pump at the same time, and the blower is immediately stopped by the signal. By remaining in (20) or still remaining in the injection nozzle, this remaining chemical is not sprayed by the pressure of the blower and falls downward.

The above-mentioned problems that occur when the quarantine device is first activated (ON) and when the quarantine device is stopped (OFF) are defined as secondary pollution. has a problem that the amount of drugs that must be supplied per unit square cannot be quarantined as much as the amount of drugs set for the occurrence of secondary pollution.
