Description

Control circuit and method for generating nano water ion steam

Technical field

The invention relates to the technical field of electrical design, in particular to a control circuit and a method for generating nano water ion steam.

Background technique

After studying by British physicist Charles Thomson Rees Wilson (1869-1959), he invented a device called the Cloud Chamber (Wilson Chamber) in 1894, which was filled with clean air and alcohol (or Saturated vapor of diethyl ether). If you break into a charged particle that is invisible to the naked eye, it becomes the core of the "cloud" condensation, forming a fog point, which shows the "footprint" of the particle motion. Therefore, scientists can use the "cloud chamber" to observe the movement and changes of elementary particles (electron protons, etc.) that are invisible to the naked eye. At the same time, many new elementary particles have also been discovered. The Wilson Cloud Room has made an outstanding contribution to the study of the micro world. In 1927, he won the Nobel Prize in Physics. Charles Thomson Rees Wilson (1869-1959), studied optical phenomena in clouds since 1894. In 1895, he designed a set of equipment to condense water vapor to form a cloud. At that time, it was generally believed that in order to condense water vapor, each mist must have a dust as the core. Wilson found that water droplets appeared when the damp, dust-free air swelled. He believes that this may be the result of water vapor condensation with conductive ions in the atmosphere. In 1895, Wilson began his research on the formation of clouds at the Cavendish Laboratory. He allowed the water vapor to swell in his designed glass container and found that the saturated water vapor encountered free dust or charged nucleus, which would condense into small water droplets, which is the cause of cloud formation.

At present, the existing steam generator generally uses an alloy heating wire or a PTC as a heating element. The alloy heating wire has the disadvantages of slow heat generation and low life. The heating temperature of the PTC electric heating element is generally only about 200 ° C, and the heating temperature is higher than 120 ° C. Generally, the use of lead trioxide is considered to be environmentally unfriendly due to the high lead content. With the improvement of the quality of life and the use requirements, the market urgently needs a steam generator which generates a large amount of water vapor in a short time and has a small volume.

In addition, the safety problem of the steam generator has attracted more and more attention, and the existing negative ion generating equipment uses the high pressure method to generate negative ions, which greatly causes the high pressure danger, and the high pressure will have the opportunity to generate ozone, which has certain harm to the human body. Sex.

In addition, nano-water ion technology is one of the charged ion evolution technologies. It is mainly used for air sterilization. The advantage is that charged ions can be sterilized. Adsorption on the surface of dust can help the filter to absorb fine dust particles and can act as humidified air. The role of long-term use of air-drying cycles, the circuits that currently produce nano-water ions are mostly specialized circuits with complex structures.
