Furthermore, icons and humidity intervals are drawn on the optical filter 21, and different icons of the optical filter are respectively drawn as patterns of nuts, preserved fruits, medicines, fruits and the like. The fluorescence generated by the humidity display film 22 and the filtering action of the optical filter 21 cause the optical filter 21 to emit light and light up the corresponding icon, thereby displaying the internal humidity and the articles suitably stored under the humidity. The humidity indicating film 22 is in contact with the air in the storage compartment and senses the humidity of the air to emit fluorescent light of different colors.
In the first preferred embodiment, the humidity indicating film 22 is provided with a humidity sensitive color changing material which shows different colors depending on the current humidity in the storage room.
For example, 1 kind of fluorescent humidity-sensitive color-changing material is added into the humidity indicating film 22, and the humidity-sensitive color-changing material can display different colors according to the humidity in the current storage room, for example, 4 humidity indicating films 22 are sequentially arranged as follows: the fluorescence wavelength range emitted when the humidity range is 20-40% is 625-740nm, and the display is red; when the humidity range is 40-60%, the emitted fluorescence wavelength range is 560-590nm, which shows yellow; when the humidity range is 60-80%, the emitted fluorescence wavelength range is 500-550nm, and the display is green; the emitted fluorescence wavelength range is 430-480nm when the humidity range is 80-100%, and blue color is displayed. For example, the filters 21 No. 1-4 can only filter red, yellow, green and blue light waves respectively, and are painted with nut, preserved fruit, medicine and fruit patterns respectively to play the roles of filtering light and sealing the upper surface of the through hole. When the slide block 11 is adjusted to increase the relative humidity of the air in the storage room, the humidity indicating film 22 sequentially emits red, yellow, blue and green fluorescent lights, and the red, yellow, blue and green No. 1-4 light filters 21 are sequentially and independently lightened under the filtering action of the light filters 21, and meanwhile, icons on the surface are lightened to show the humidity range of the air in the storage room and articles suitable for storage.
The following are described as specific examples:
a) when the relative humidity in the storage room is in the range of 20-40%, 4 humidity indicating films can emit red fluorescence, but only the red fluorescence of No. 1 humidity indicating film can penetrate through the filter 21, the No. 1 filter turns red, the nut pattern on the No. 1 humidity indicating film is lightened, and at the moment, other filters are colorless, and the nut pattern is not lightened.
b) When the relative humidity in the storage room is in the range of 40-60%, 4 humidity indicating films can emit yellow fluorescence, but only the yellow fluorescence of No. 2 humidity indicating film can penetrate through the filter 21, the color of the No. 2 filter is changed into yellow, the preserved fruit pattern on the color filter is lightened, and at the moment, other filters are colorless, and the pattern is not lightened.
