Description

Electrostatic liquid spraying device

Technical Field

The utility model relates to the field of public health safety, in particular to an electrostatic liquid spraying device capable of uniformly spraying and automatically adsorbing liquid.

Background

Since the epidemic situation, the disinfection of public areas has become a daily routine. Conventional disinfection involves exposing the disinfecting liquid to the area to be disinfected by means of a spray. However, the operation mode is difficult to kill the back of the barrier and other surface areas where the fog drops can not be attached, which brings potential safety hazards to public safety and sanitation killing.

An improved mode is that the electrostatic spraying technology is utilized, and high-voltage static electricity is added to the disinfectant, so that the fog drops can be automatically adsorbed to the back surface and other areas of an object. As in patent CN106687218B, an electrostatic spraying device is disclosed which is configured to deliver a fluid, such as a disinfectant fluid, onto a surface to be cleaned by charging the fluid and causing the fluid to form a mist (mist), fog (fog), spray (plume) or spray (spray) which can be directed onto the surface. The system uses a high air (or other gas) flow to atomize the fluid and pass the fluid past electrodes within the nozzle assembly to charge, e.g., negatively charge, the droplets of the fluid being atomized. Through the nozzle design, the fluid can be atomized into droplets of various sizes. In addition, the system is powered by a DC power system rather than an AC system, thereby eliminating cumbersome power cords. The device may charge a liquid or gas, or positively charge.

However, the liquid is charged by supplying power to the liquid, and the liquid is sprayed out and then forms an adsorption effect under the electrostatic action, which requires a very high voltage. Under high voltage, when a hand touches the metal sheet of the grounding terminal, obvious electrical tingling feeling can be formed on the hand, which causes bad experience to users. On the other hand, if the voltage is lowered, the feeling of numbness can be reduced, but the effective electrostatic adsorption effect cannot be achieved.

Therefore, there is a need to improve the high voltage electrostatic module in the current electrostatic spraying device to solve the existing contradiction between high voltage and hand anesthesia.
