Abstract
Description
[Technical Field]
[0001] The present invention relates to a mist evaporation heat generator and a handheld fan equipped with the mist evaporation heat generator. [Background technology]
[0002] Conventionally, handheld fans only blow air, so they only provide a slight feeling of coolness, which is unsatisfactory. Summary of the Invention [Problem to be solved by the invention]
[0003] The object of the present invention is to provide a mist evaporation heat generator and a handy fan that can give users a sense of satisfaction.
[0004] In order to solve the above problems, the mist evaporative heat generator and handy fan of this invention are mist evaporative heat generators equipped with a water tank for holding water and a mist spraying means for converting the water in the water tank into mist and spraying it from a mist nozzle, and are characterized in that high pressure is applied to the water in a pressure chamber by pressure applied by a lever provided on the mist spraying means, and the pressurized water is sprayed as mist from the mist spraying means. In this invention, it is desirable to make the water droplet passages 0.2 mm in diameter in order to make the mist particles small. In this invention, it is desirable to equip the handheld fan with a mist evaporation heat generator.
[0005] According to claim 1, the efficiency of people who want to work outside is improved, and work efficiency is improved. Claim 2 is similar to the above. [Brief explanation of the drawings]
[0006] [Figure 1] Side view of a mist evaporation heat generator. [Figure 2]FIG.
[0007] An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. The mist evaporative heat generator 1 includes a water tank 2 for storing water and a mist spraying device 4 that converts the water in the water tank 2 into mist and sprays it from a mist nozzle 3. A lever 5 attached to the mist spraying device 4 applies high pressure to the water in a pressure chamber 6, and the pressurized water is sprayed as mist from the mist spraying device 4. The pressure applied by the lever 5 is supported by a support 7, forcing a piston 8 into the pressure chamber 6. This pressure applies pressure to the water from above, causing mist ranging in size from a few microns to several tens of microns to be sprayed from the mist nozzle 3. When the lever 5 is released, a spring 9 pushes the piston 8 upward, emptying the pressure chamber 6 and creating a negative pressure. This negative pressure draws water up from below through a bearing 10, filling the chamber with water and preparing it for the next spray. As shown in FIG. 2, when the stopper 11 is facing sideways, no mist is emitted from the mist nozzle 3 even when the lever 5 is pulled. When the stopper 11 is parallel to the lever 5, pulling the lever 5 causes mist to come out of the mist nozzle 3. The diameter of the water droplet passage is set to 0.2 mm to make the mist particles small. [Explanation of symbols]

Claims
1. A mist evaporation heat generator comprising a water tank for storing water and a mist injection means for converting the water in the water tank into mist and injecting it from a mist injection port, characterized in that high pressure is applied to the water in a pressure chamber by pressure applied by a lever provided on the mist injection means, and the pressurized water is then injected as mist from the mist injection means.
2. 2. A mist evaporation heat generator according to claim 1, wherein the diameter of the water droplet passage is 0.2 mm to reduce the size of the mist particles.
3. A handy fan equipped with the mist evaporation heat generator according to claim 1 or 2.
