This system is mainly composed of a control unit, is composed of an operation unit and a display unit, and controls the pump 2, the fan 6 and the heater 51. FIG. 4 is a circuit diagram showing a more detailed structure of this control system. This circuit is composed of a control board 91, which is mainly composed of a CPU 92, as a control unit, and an input circuit and an output circuit thereof. Input circuit is AC / D
A power supply circuit C1 including a C converter 93, a time setting button switch 94 for setting a current time, a start time and an end time for operating a timer, selection of those setting contents, and a large / medium / small room size. A switch circuit C2 in which a selection button switch 95 to be selected, a setting button switch 96 for registering setting values, a continuous discharge button switch 97, and a manual / automatic button switch 98 for manual / automatic switching are arranged, a vibration sensor 99, and a temperature. The detection circuit C3 is provided with the sensor 7. On the other hand, the output circuit includes the time display element 100, the current time, the start time, the end time,
Each LE with large, medium and small room sizes and manual display
A display circuit C4 in which D101 is arranged, a drive circuit C5 in which a motor of the blower fan 6 and a heater 51 are arranged, a drive circuit C6 in which a motor of the bellows pump 2 is arranged, and a buzzer 10
And a drive circuit C7 in which 2 is arranged. Among them, the vibration sensor 98 constitutes detection means for detecting the vibration of the device and stopping the operation for earthquake countermeasures, and the buzzer 102 makes a confirmation sound at the time of an emergency stop due to the vibration, setting by each setting button switch, or driving. It constitutes an alarm means for issuing.

In the apparatus thus constructed, when the control system is set to the timer-operated automatic operating state, the pump 2 is operated when the predetermined set time is reached, so that the liquid medicine from the medicine container 1 is sucked. Discharge tube 2
After 0, it flows down to the main evaporation part. The chemical liquid that has flowed down first flows down through the slanted trough 32 while diffusing into the liquid retaining liquid 31 of the evaporation means 3a above the main evaporation portion, and the dropping hole 3
When it reaches 5, it is dripped into the gutter 34. Further, the chemical liquid that has flowed down the trough 34 is diffused and retained in the liquid retention liquid 31 of the evaporation means 3b below, and reaches the dripping pipe 36 along the trough 32 with an excessive surplus, and flows down to the last sub evaporation portion. . The discharge amount of the medicine at this time is defined by the operation time of the pump 2, and is, for example, about 2 to 6 cc for one discharge operation. Note that the ejection interval is, for example, once an hour in relation to the time required to complete the evaporation of the ejected drug, and the ejection frequency is in relation to the size of the room and the time width in which the evaporation can be permitted. For example, it is set to 1 to 6 times.

The chemical liquid thus discharged is energized to the heaters 51 arranged behind the main evaporation portion and immediately below the sub evaporation portion in accordance with the program set in the CPU 92 of the control system, so that the gutters 32, 34 are connected. And heat the saucer 33,
When the blower fan 6 is started, first, the chemical liquid is mainly preheated in the upper evaporation means 3a, is fully heated and evaporated by the lower evaporation means 3b, and is finally supplemented by the evaporation means 3c. The vaporized vapor is discharged into the atmosphere from the air outlet 90 of the cabinet 9 of the device by being blown by the fan. During this operation period, the heater 51 is on / off controlled according to the temperature detected by the temperature sensor 7.

At the time when the evaporation of the drug is almost completed,
After stopping the pump 2 and stopping the liquid supply, heating by the heater 51 and the blowing of the blowing fan 6 are continued to evaporate the medicine, and when the off time set by the timer is reached, the operation of the blowing fan 6 is stopped. Stop the operation of the device. When the evaporation of the drug is completed in this way, it is unavoidable that a residue of the drug remains in the sub-evaporation part, but the remaining residue is dissolved by the solvent in the chemical solution during the next evaporation operation, It falls into the collection container 4.

The above-described series of operations are performed by controlling the pump 2 according to a program of an operation pattern preset in the CPU 92 of the control system. That is, the operation in which the discharge amount and the number of discharges are controlled by the operation time of the pump 2 is performed within a certain limited time width registered by the timer setting. Naturally, the button switches 94 to 98 during operation
The operation pattern can be changed by operating.

Further, in this embodiment, although not directly related to the above-mentioned evaporation operation, means for preventing the leakage of the chemical liquid during the suspension of the operation of the apparatus is also taken. That is, as shown in FIG. 1, the space above the drug container 1 is connected via a pressure balance tube 80 to a shock absorber 8 that absorbs expansion of the gas in the container 1 due to temperature rise. The shock absorber 8 is composed of a container having a space divided into two parts at the top and bottom,
Water W is filled below the partition 81. And
The tip of the balance tube 80 is opened through the partition 81 into the space below which is filled with the water W. Partition 81
A pipe extending downward from is provided, and the lower end of the pipe opens at a deep position in water. The upper space of the partition 81 of the shock absorber 8 is open to the atmosphere.

With this configuration, even if the gas in the medicine container 1 expands due to the rise in the ambient temperature, the expanded gas is discharged into the water of the buffer 8 through the balance tube 80, and the water W removed by that amount is discharged. Is extruded through the pipe 82 into the space above the partition 81, and prevents the pressure inside the medicine container 1 from rising. This makes it possible to prevent the chemical solution from leaking out while the operation of the device is stopped. On the contrary, when the ambient temperature decreases and the pressure in the drug container 1 decreases, the gas released into the water of the buffer 8 returns to the balance tube 80 and prevents the negative pressure in the drug container 1 from being generated. At this time, when the negative pressure is increased to the extent that the water W of the shock absorber 8 is sucked into the balance tube 80, the check valve 11 of the drug container 1 is opened and the atmosphere is sucked into the balance tube 80. Prevent suction of water W.
