Description

Dual medium ultrasonic atomization device

Technical Field

The application relates to an ultrasonic atomization device, in particular to a dual-medium ultrasonic atomization device.

Background

At present, in production or life, an ultrasonic atomization sheet is often utilized to atomize a solution such as hydrogen peroxide with a certain concentration, and then the atomized hydrogen peroxide molecular group is utilized to disinfect the surface of the object to be disinfected in the disinfection chamber. The hydrogen peroxide molecule has a certain killing effect on viruses or harmful bacteria when decomposing, so that the disinfection and sterilization of the articles to be disinfected can be realized. After being decomposed, the hydrogen peroxide can be reduced into water and oxygen, and can be directly discharged into the environment, so that the disinfectant is a very clean and environment-friendly disinfectant, and the disinfection and sterilization mode in the form of hydrogen peroxide dry fog is also more and more widely adopted.

The single crystal piezoelectric ceramic is utilized for ultrasonic atomization to atomize the hydrogen peroxide disinfection solution, so that dry fog can be generated to disinfect the surface of an object. Because the atomizing piece produces the ultrasonic vibration of vertical direction under the power module drive of high-frequency vibration, the energy of ultrasonic wave needs to have certain liquid degree of depth, just can conduct the energy of ultrasonic wave in order to reach atomizing effect.

The traditional ultrasonic atomization device generally has the defects of small atomization amount, large atomized particles and failure to achieve the intended purpose of atomization because the liquid level of the liquid to be atomized is not high enough. Meanwhile, the situation that the atomizer heats and burns dry exists, and the service life of the atomizer is reduced. In order to ensure the liquid level, the conventional atomizer needs to maintain a sufficient amount of liquid to ensure the atomization effect. So that the disinfectant cannot be completely atomized after each sterilization, resulting in a relatively large amount of disinfectant remaining each time. Because the chemical property of hydrogen peroxide is unstable, the residual quantity can be gradually decomposed into water and oxygen in the cavity along with time, only water remains after the oxygen volatilizes, and when the hydrogen peroxide solution is added next time, the concentration of the hydrogen peroxide is diluted by the water, so that the effective content of the disinfection factors is reduced, the concentration of the disinfection effect cannot be achieved, the disinfection result is affected, and the disinfection is failed or unreliable.

Accordingly, the applicant devised a dual medium ultrasonic atomizing device to solve the above-mentioned problems.
