BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vaporizing device for vaporizing chemicals such as fragrances, deodorants, germicides and insecticides.

[0002]

2. Description of the Related Art As conventional evaporation devices, those shown in FIGS. 23 and 24 are known. That is, the evaporation device is composed of a device body 61 and a chemical liquid cartridge 62 that is detachably mounted in the device body 61. The apparatus main body 61 has an outer case 63, an evaporation port 64 is opened on the upper surface of the outer case 63, and an insertion port 65 is formed on the lower surface. A tubular portion 66 is provided above the inside of the outer case 63, and a female screw portion 67 is formed on the inner periphery of the lower portion of the tubular portion 66. Further, a heater 69 having an insertion hole 68 at the center is arranged at the upper end of the tubular portion 66, and a cord wired from a power cord port 70 is connected to the heater 69.

On the other hand, the chemical liquid cartridge 62 has a chemical liquid container 72 having a circular cross section in which a chemical liquid 71 having a predetermined effect such as fragrance is contained, and the female screw portion 67 is provided on the upper peripheral portion of the chemical liquid container 72. A male screw portion 73 that is screwed into is formed. Further, a cap 74 is fitted to the upper end opening of the chemical liquid container 72, the upper end of which projects outside the chemical liquid container 72 and the lower end of which is the bottom surface of the chemical liquid container 72 at the center of the cap 74. Liquid absorbing core 75 extended to the vicinity
Is fitted.

In such a structure, in use, the chemical liquid cartridge 62 is inserted into the external case 63 through the insertion port 65.
Insert inside and rotate. Thereby, as shown in FIG. 24, the male screw portion 7 provided on the upper end portion of the chemical liquid container 72 is provided.
3 is screwed into the female thread portion 67 provided on the tubular portion 66, and the chemical liquid cartridge 62 is loaded into the apparatus main body 61. Thus, when the chemical liquid cartridge 62 is loaded, the upper end of the liquid absorbent core 75 is loosely inserted into the insertion hole 68 of the heater 69. In this state, the heater 69 operates to generate heat, whereby the drug component evaporates from the liquid absorbent core 75 and diffuses to the outside through the evaporation port 64.

[0005]

However, the chemical liquid 71 used in such a conventional evaporation apparatus inevitably contains residual components that cannot be evaporated.
For this reason, when the evaporation period is long, a large amount of residual components remain in the liquid absorbent core 75, which causes the liquid absorbent core 75 to be clogged and its liquid absorbing performance to deteriorate, and the liquid absorbent 71 to the upper end portion. Leaching is also reduced. As a result, the amount of evaporation from the upper end of the liquid suction core 71 gradually decreases as the evaporation period elapses. As a result, the fragrance effect of the fragrance and the drug effect such as the deodorant effect of the deodorant are gradually reduced, and a stable drug effect cannot be obtained during the period of use.

The present invention has been made in view of such conventional problems, and an object of the present invention is to provide a transpiration apparatus capable of obtaining a stable drug effect over a long period of time.

[0007]

In order to solve the above problems, in the present invention, a chemical solution container in which a chemical solution is sealed, and a chemical solution deriving means for deriving the chemical solution from the chemical solution container to the outside,
Evaporation means for evaporating the chemical solution that has been extracted to the outside by the chemical solution deriving means, storage means for storing data indicating the change over time in the amount of the chemical solution evaporated per unit time by the transpiration means, and transpiration of the transpiration means. There is a reading means for reading data corresponding to the accumulated value of time from the storage means, and a control means for controlling the evaporation time per unit time of the evaporation means based on the data read by the reading means. is doing.

[0008]

In the above structure, when the chemical liquid discharging means discharges the chemical liquid in the chemical liquid container to the outside, the vaporizing means vaporizes the chemical liquid thus dispensed. At this time, the reading means reads the data corresponding to the temporal change indicated by the accumulated value of the evaporation time of the evaporation means, that is, the data on the evaporation amount which the evaporation means can evaporate in a unit time at the present moment. Then, the control means, based on this data, evaporates the evaporation means per unit time.
The transpiration time is controlled, and thus the transpiration amount from the transpiration means is controlled according to the accumulated value of the transpiration time.

FIG. 5 shows the protruding portion 135 when the evaporation thermistor 118 is continuously operated at a constant temperature.
5 is a graph showing the change over time in the amount of transpiration from the. That is, the chemical liquid 132 inevitably contains residual components that cannot be evaporated. Therefore, if the evaporation period is long,
A large amount of the residual component remains in the liquid absorbent core 133, which causes the liquid absorbent core 133 to be clogged and the liquid absorbent performance to deteriorate.
The leaching amount of 32 into the protruding portion 135 is also reduced. as a result,
The amount of transpiration from the upper end of the liquid absorbent core 133 gradually decreases as the transpiration period elapses, and completely ceases to evaporate after 32 days.

The data obtained by converting the graph shown in FIG. 5 into data is the ROM data of the amount of transpiration from the liquid-wicking core shown in FIG. 6, which is stored in the ROM 146. This ROM data is obtained by dividing 32 days into 16 and storing the values of the graph of FIG. 5 in 16 areas corresponding to addresses 0 to 15 with the maximum value being "70" and the minimum value being "1".

The RAM 153 is provided with the total elapsed time register ZR, the evaporation time register JR, the energization management register TR, and the end time register KR shown in FIG. The total elapsed time register ZR is a register for accumulating and storing the time since the new chemical liquid cartridge 102 was loaded, and the date from the 1st day to the 32nd day is 0 to 3.
1, a day register ZHR, a time register ZJR for storing time data of 0 to 23, a minute register ZFR and a second register ZBR for storing minute data and second data of 0 to 59, respectively.

The transpiration time register JR is a register for managing the time during transpiration operation starting from the transpiration start time, and like the total elapsed time register ZR, the day register JH.
R, hour register JJR, minute register JFR, second register JBR and the like. In addition, the energization register TR
Indicates a 1-bit configuration, "0" indicates interruption, and "1" indicates energization. The end time register KR is a register used for unit time management for keeping the transpiration amount substantially constant within one hour with the unit time being one hour. In the present embodiment having the above-described configuration, the chemical liquid cartridge 102 is inserted into the cartridge loading portion 121 through the insertion port 122 before use. Then, the protruding portion 135 of the liquid absorption core 133 is inserted into the liquid absorption core passage 123 and reaches the evaporation thermistor 118. Further, the liquid medicine 132 is the absorbent core 1
33 and then to the protruding portion 135, and thus the protruding portion 1
The chemical solution 132 is constantly supplied to 35.

In this state, if a power source not shown in the figure is turned on, C
The PU 145 starts control according to the main routine shown in FIG. That is, first, the transpiration time register JR
Then, the total elapsed time register ZR is reset to 0 (SA1), and the energization management register TR is reset to 0 (SA2). After executing the initialization processing of SA1 and SA2, the reset SW 152 and the evaporation start SW1
The state of 51 is discriminated (SA3, SA4), and the evaporation process (SA6) is executed when the evaporation start button 140 is operated and the evaporation start SW 142 is turned on.

Further, by performing this evaporation process, the chemical liquid 132 in the chemical liquid cartridge 102 disappears, and when a new chemical liquid cartridge 102 is loaded,
The reset button 150 is operated. Then reset S
W152 is turned on, the process proceeds from SA3 to SA5, and the total elapsed time register Z that has accumulated the elapsed time until then
R is reset to 0.

The evaporation process (SA6) is executed according to the flow shown in FIG. 9, and the evaporation time register JR is set to 0.
After resetting (SB1), read the ZHR data (S
B2). This ZHR data is based on the chemical solution cartridge 10
It is the data of 0 to 31 corresponding to the first day to the 32nd day after loading 2. Therefore, in the processing in the next SB3, X, which is the integer part of ZHR / 2, is any value of 0 to 15 depending on the number of elapsed days. Then, in SB3, the value of 0 to 15 corresponding to the elapsed days is set to X, and then the address X is read from the elapsed time ROM data shown in FIG.
Data is read, and the read data is set to Y (SB4). Then, the integer part of 60 / Y is set to Z (SB5), and the value of Z determines the value of "minute" of evaporation time for 1 hour. Next, the two digits of the decimal point of 60 / Y are set to V (SB6), and (60/100) × V is set to W (SB7), and the value of "second" of the evaporation time is determined by the value of W.

More specifically, the processing of SB2 to SB7 will be described in detail. For example, if it is the 10th day after the new chemical liquid cartridge 102 is set at the present time, ZHR = 9, and the value of this ZHR is SB2. Read “9”. Also, since the integer part of 9/2 is "4", X = 4 in SB3, and in SB4, the data "53" at the address "4" is read from the time-varying ROM data of FIG. 6 and Y = 53. And Also, 60 / Y = 60 /
Since the integer part of 53 is "1", Z = 1 in SB5
Since two decimal places of 60/53 are "13", SB6 is set to V = 13. Furthermore, (60/10
0) × 13 = 7.8, but in the present embodiment, the value of the second after the decimal point is not handled, so SB = W = 7.
And Based on the above Z and W values, the duration of transpiration on the 10th day is "1 minute 7 minutes" for 1 hour.
Seconds "are calculated.

If, for example, the present time is the 29th day after the new chemical liquid cartridge 102 is set, Z
Since HR = 28, SB2 reads the ZHR value "28". Also, since the integer part of 28/2 is "14", X = 14 in SB3 and in FIG.
The data "2" at the address "14" is read from the ROM data of the change with time, and Y = 2 is set. Also, 60 / Y =
Since the integer part of 60/2 is "30", Z = 30 in SB5, and the two decimal places of 60/2 is "00", so V6 is set in SB6. Furthermore, (60 /
Since 100) × 00 = 0, SB = 0 is set to W = 0. With the above Z and W values, the time for which transpiration continues on the 29th day is "30 minutes 0
Seconds "are calculated.

At SB8 subsequent to SB7, the energization management register TR is set to indicate that electricity is being supplied, and then the heater control circuit 148 is instructed to energize the evaporation thermistor 118. As a result, the evaporation thermistor 118 operates to generate heat, and the protruding portion 135 of the liquid suction core 133 is heated,
The chemical liquid 132 leaching into the liquid absorbent core 133 starts to evaporate. Subsequently, the timer increment process is executed, and the timer increment process is performed according to the flow shown in FIG.

That is, first, it is determined whether or not TR = 1, that is, whether or not the evaporation thermistor 118 is energized (SC1), and if energized, a timer interval is generated at 1 second intervals. It is determined whether or not a rapto has entered (SC2). If a timer interrupt is input during energization, the second register JBR of the evaporation time register JR is incremented (SC3), and then it is determined whether JBR becomes "60" (SC4). If JBR = 60, JBR is reset to 0 (SC5), the minute register JFR of the transpiration time register JR is incremented (SC6), and it is determined whether or not JFR becomes "60" (SC7). . If JFR = 60, JFR
After resetting 0 to 0 (SC8), register J within the evaporation time
When R, the register JJR is incremented (SC9),
It is determined whether JJR has become "24" (SC1
0). If JJR = 24, JJR is reset to 0 (SC11), the day register JHR of the evaporation time register JR is incremented (SC12), and SC14 is set.
The following processing is executed. That is, the above SC3 to SC1
By the process of 2, carry is carried out in the order of minute, hour, day.

If TR = 0 and the energization is stopped, the process proceeds from SC1 to SC13, and the same determination process as that of SC2-SC12 described above is executed in SC14-SC.
23, seconds, minutes, hours of the total elapsed time register ZR,
This is performed for the date registers ZBR, ZFR, ZJR and ZHR. Therefore, the transpiration time register JR seconds, minutes,
While the hour / day registers JBR, JFR, JJR, JHR accumulate the time during energization, the seconds, minutes, hours, day registers ZBR, ZFR, ZJ of the total elapsed time register ZR are accumulated.
R and ZHR accumulate the time after the evaporation start SW 142 is turned on, regardless of whether or not electricity is being supplied.

In the flow of FIG. 9, after the above timer increment processing (SB10) is executed, it is determined whether the evaporation stop SW 151 is turned on, and if it is turned on, the heater control circuit 148 is evaporated. It is instructed to prohibit energization of the thermistor 118 (SB21). If the evaporation stop SW 151 continues to be in the off state, it is determined whether Z calculated in SB5 is "60". Here, the case of Z = 60 means the ROM of FIG.
Only when the data "1" of the address 15 is read from the data, that is, the 31st and 32nd days. In the case of both days, the loop of SB10 to SB12 is repeated, and therefore, the evaporation stop SW15 on the 31st and 32nd days.
The evaporation thermistor 118 continuously maintains the heated state until 1 is turned on, and evaporation is performed over the whole day.

When Z ≠ 60, JFR =
It is determined whether or not Z (SB13), and when JFR = Z, it is determined whether or not JBR = W (SB14). That is, the SB 13 and SB 14 determine whether or not the transpiration time minutes (Z) and seconds (W) for one hour calculated in advance in SB5 and SB7 have been reached, and if they have reached the transpiration time, the heater control circuit 148 is reached. An instruction to prohibit energization of the evaporation thermistor 118 is issued (SB15). Next, the energization management register TR
After resetting (SB16), the current time register Z
The value of JR is set in the end time register KR (SB1
7).

Further, the timer increment process described above is executed (SB18), and it is determined whether or not the evaporation stop SW 151 is turned on (SB19). Evaporation stop SW
If 151 is not turned on, it is determined whether KR ≠ ZJR (SB20) and S is continued until KR ≠ ZJR.
The loop of B18 to SB20 is repeated. That is, ZJ
Since R is incremented every 60 minutes, the standby state is maintained by the loop until 60 minutes have elapsed, and when 60 minutes have elapsed and KR ≠ ZJR, the processing from SB2 is restarted. To do. Therefore, SB2
Is executed every 60 minutes = 1 hour, and the evaporation thermistor 118 performs a heating operation for a time length corresponding to the number of elapsed days with respect to 1 hour which is this unit time.

In this embodiment, the evaporation is started under the condition that the evaporation start button 140 is operated and the evaporation start SW 142 is turned on.
It is also possible to detect the loading of the chemical liquid cartridge 102 and start the evaporation in response to the detection.

That is, if n = 1, first TR (1) = 1
Is determined, that is, whether or not the thermistor 205 for transpiration of the chemical liquid 1 is energized (SG1), and if energized, it is determined whether or not a timer interrupt generated at 1 second intervals is entered. It is determined (SG2). If a timer interrupt is input during energization, after incrementing the second register JBR (1) of the evaporation time register JR (1) (SG3), whether JBR (1) becomes "60" or not Is determined (SG4). JBR (1) = 60
If JBR (1) is reset to 0 (SG
5), transpiration time register JR (1) minute register JF
R (1) is incremented (SG6), JFR (1)
Is determined to be "60" (SG7). JF
If R (1) = 60, JFR (1) is reset to 0 (SG8), then the hour register JJR of the evaporation time register JR is incremented (SG9), and JJR
It is determined whether (1) has become "24" (SG1
0). If JJR (1) = 24, JJR (1)
Is reset to 0 (SG11), the day register JHR (1) of the transpiration time register JR (1) is incremented (SG12), and the processes from SG14 onward are executed.

If TR (1) = 0 and the energization is stopped, the process proceeds from SG1 to SG13, and the same determination processing as in SG2 to SG12 described above is performed in SG14.
~ SG23, seconds of the total elapsed time register ZR,
Minute, hour, day registers ZBR (1), ZFR (1), ZJ
This is performed for R (1) and ZHR (1). Therefore, the transpiration time register JR (1) has seconds, minutes, hours, and days registers JBR (1), JFR (1), JJR (1), and JHR.
(1) accumulates the time during energization, while the total elapsed time register ZR (1) shows the seconds, minutes, hours, and days register Z.
BR (1), ZFR (1), ZJR (1), and ZHR are (1), regardless of whether or not they are energized, 1 chemical liquid SW
The time since 217 is turned on is accumulated.

After performing the above timer increment processing, in SF11 following SF10 in FIG. 18, it is determined whether or not the evaporation stop SW 221 is turned on, and if it is turned on, the evaporation stop processing is executed. (SF
12). This evaporation stop processing is performed according to the flow shown in FIG. 20, and first, the state of the register SR is determined (SH.
1). As a result of this determination, if SR = 01, and the chemical liquid 1 is being evaporated, the heater control circuit 2 for the chemical liquid 1 concerned
26, thermistor energization stop instruction (SH2), SR
= 10 and the chemical solution 2 is being evaporated, the thermistor energization stop instruction is given to the chemical solution 2 heater control circuit 227 (SH3). Further, SR = 11, and the chemical liquid 3
Is transpiring, the heater control circuit 228 for the chemical liquid 3 is instructed to stop energizing the thermistor (SH4),
Then, "00" is set in SR (SH5).

If the evaporation stop SW 221 continues to be in the off state, the process proceeds from SF11 to SF13 in the flow chart of FIG. 18, and Z calculated in SF5 is "6".
It is determined whether or not 0 ". Here, when Z = 60, as described in the first embodiment, the data" 1 "at the address 15 is read from the ROM data in FIG. In the case of both days, that is, the 31st day and the 32nd day, and both of these days, SF10 → SF11 → S
Repeat the loop of F13.

If Z ≠ 60, then JFR
(1) = J is determined (SF14), JFR (1)
= Z, it is determined whether or not JBR (1) = W (SF15). That is, SF14 and SF15 are
It is determined in advance whether or not the vaporization time minutes (Z) and seconds (W) for 1 hour calculated in SF5 and SF7 have been reached, and if they have reached the vaporization time, the chemical liquid 1 heater control circuit 226 is provided with the chemical liquid 1 vaporization thermistor. An energization prohibition instruction is issued to 205 (SF1
6). Next, after resetting the energization management register TR (1) (SF17), the value of the current time register ZJR (1) is set in the end time register KR (SF18).
Further, the timer increment processing described above is executed (SF19), and it is determined whether or not the evaporation stop SW 221 is turned on (SF20).

If the evaporation stop SW 221 is not turned on, it is judged whether KR ≠ ZJR (1) (SF2
1), SF19 to SF2 until KR ≠ ZJR (1)
Repeat the loop of 1. That is, ZJR (1) is 60
Since it is incremented every minute, 60
The waiting state is maintained by the loop until minutes pass,
When 60 minutes have passed and KR ≠ ZJR (1),
The processing from SF2 is restarted. Therefore, the processing from SF2 is executed every 60 minutes = 1 hour, and the chemical solution 1 is used for a time length corresponding to the number of elapsed days with respect to 1 hour which is the unit time.
