Description
The present invention relates to wick medicaments such as insecticide and pest repellant be attracted up to be evaporated the medicament evaporation device and the medicament evaporation method of diffusion.
In the past, for the purpose of desinsection, the method that medicament is added hot flashing had: (1) mosquito-repellent incense; (2) electrothermal kill mosquito pad etc. is subjected to the user and welcomes.
In recent years, porous matter wick is immersed in the liquid medicine, this mode that makes medicament add hot flashing is heated on the top of core,, and attract much attention again owing to the reasons such as the pad and the effect of evapotranspiring are stable for a long time of need more not changing dressings at every turn.
The appearance of this mode still quite early, was for example once being reported direct-fired mode in real public clear 43-25081 communique, but the decomposition of medicament is violent when directly heating, so the tendency of employing indirect mode is generally arranged.The indirect mode has: clip the heating means of felt pan etc. between wick and heater, be disclosed in real public clear 36-12459 communique and real public clear 46-22585 communique; Also separate the method that certain distance heats between handlebar wick and the heater, be disclosed in real public clear 43-26274 communique, real public clear 44-8361 communique, real public clear 45-14913 communique and real public clear 45-292445 communique.
In the past, the typical structure of this device, as shown in figure 12.That is: with the keeper 3 chimeric bottleneck edge parts of adorning at medical liquid container 15, wick 2 is inserted in the maintenance tube 8 of this keeper 3, wick is remained on setting height, heater 20 is set near the upper end of wick 2, heat on top to wick 2, and wick 2 is just evaporated diffusion to the soup 4 that drinks up in medical liquid container 1.
Yet, this in the past device, the variation of ambient air temperature raises the pressure in the container owing to keeping, transportation and when using, thereby problem such as medicine liquid leakage often takes place.In order to address this problem, the medicament evaporation device of perforate on a kind of maintenance tube 8 at keeper 3 is disclosed in real public clear 60-125876 communique, but in this case, having any problem aspect the shaping of keeper, the shaping cost is also high, and the quantitative change of container inner liquid medicine presses liter in can not the depressant liquid container after a little while after long-time the use, spilling of inevitable soup, this is a present case.
In addition, also there is following problems in the sort of in the past medicament evaporation device shown in Figure 12.That is: when wick 2 is inserted the maintenance tube 8 of keepers 3, keep the height set, but as following said, this wick 2 is to utilize porous material that capillarity drinks up the soup 4 in the medical liquid container 1.Therefore, as mentioned above, when the wick 2 of porous matter being inserted when keeping tube 8, if keep the external diameter of the internal diameter of tube 8 less than wick 2, wick just is difficult for inserting logical, sometimes wick is damaged.So, if an internal diameter that keeps tube 8 is strengthened, though wick 2 is inserted easily, the problem of Chu Xianing is in this case, and wick 2 is moved in keeping tube 8 because of long-term vibration etc., can not keep desired location and occurs misplacing.
Another problem is that the porous matter wick that past attempts uses the felt of original form to use as above-mentioned medicament evaporation device generally is that liquid absorption is too much, when keeping, transportation and use, soup can be by wick and excessive, or because of its soft cause, is difficult for wick is installed correct.
Therefore, what use now mainly is, with the fixing wick that is shaped of material water solubleness slurries such as inorganic powder or inorganic powder and wood powder (referring to the public clear 61-23163 of spy number, spy public clear 59-40409 number, spy open clear 63-24841 number, the spy opens clear 63-6330 number and the spy opens each communique clear 63-74440 number).In addition, the inventor etc. also proposed a kind of wick that the coccoid that adds organic dust in calcium carbonate, magnesia or the magnesia fix with slurries, and formerly once proposed patent application (special hope clear 63-328526 number).
But, these wick in the past, unusual trouble all in the manufacturing, and aspect manufacturing technology, also have many difficulties (as the reproduction performance of dry, the dimensional stability and the performance of evapotranspiring etc.), in addition, shape also has certain restriction.Also have a problem to be, because these wick have the surface-active of inorganic coccoid, so soup often is subjected to chemical breakdown.In addition, these wick adopted organic water-soluble slurries such as starch, CMC-Na more owing to be convenient to make in the past, in the case, when if soup is aqueous solution,, can makes the deterioration of wick generation physical property certainly and be not durable because of dissolving, segregation, the expansion of slurries.
As mentioned above, the sort of in the past medicament evaporation device, the structure of its wick and performance are perfect not enough, and in the fixing each side of shaping, soup leakproof and the wick of wick keeper, need improvements in addition.In addition, soup evaporation method aspect also exists the medicament evapotranspiration of wick and the adjusting difficulty of speed, problems such as wick weak point in service life.
