Problems solved by technology

However, for the existing centrifugal atomizing disc, it is actually impossible to achieve the ideal high speed. On the one hand, high speed will inevitably require a very large power. On the other hand, if the rotating speed reaches a certain level, the atomizing disc will be directly broken due to vibration. , so, due to the power and its own vibration, the rotation speed of the atomization disc is limited, and the size of the atomized particles of the atomization disc is also limited, which affects the spraying effect and causes a certain waste of liquid medicine
[0004] Due to the limitation of the rotation speed of the existing atomization device, the average particle size of the droplets is generally above 80 microns, and the droplets are not uniform, so the atomization effect cannot meet the operation requirements. How to improve the fog without considering the rotation speed? The atomization effect, especially the atomization effect of the average particle size of the droplets with uniform droplets below 30 microns, is the problem to be solved by this program

Abstract

The invention discloses a centrifugal atomizing device which comprises a centrifugal atomizing disc, wherein multiple diversion trenches are formed in the centrifugal atomizing disc. The centrifugal atomizing device is characterized in that a ring body is arranged on the outer side of the centrifugal atomizing disc; the ring body and the centrifugal atomizing disc are coaxial with each other and are rotationally arranged relative to each other; a spacing is formed between the ring body and the centrifugal atomizing disc in a radial direction; the centrifugal atomizing disc rotates at the periphery to form a positive wind field; the positive wind field rotates clockwise and anticlockwise around the center of the centrifugal atomizing disc; the ring body provides a reverse wind field betweenthe ring body and the centrifugal atomizing disc in an operating state; and the reverse wind field weakens or reverses the positive wind field, so that an accelerated wind zone is formed between thecentrifugal atomizing disc and the ring body. Therefore, the relative velocity of liquid drops and air is increased, and the aim of multiplying the atomizing effect is achieved.

Description

technical field [0001] The invention relates to a centrifugal atomization device, which can be used in a spraying device, including a hand-held spraying device and a drone for spraying. Background technique [0002] Atomization is the act of dispersing a liquid into tiny droplets through a nozzle or with a high-velocity air stream. A large number of dispersed liquid droplets that are atomized can float in the air to increase the contact area with the sprayed object and improve the spraying effect. The methods of liquid atomization include pressure atomization, gas atomization, centrifugal force atomization, and sonic atomization. It means that the liquid is turned into small droplets through a special device and sprayed out in the form of mist. [0003] Centrifugal force atomization means that the atomizing disc rotates at high speed under the action of the motor. Due to the action of centrifugal force, the liquid stretches into a thin film on the surface of the rotating a...
