SPRAYING DEVICE WITH GOOD SPRAYING EFFECT Russian patent published in 2024 - IPC B05B1/00 

FIELD: liquid atomisation or spraying devices.

SUBSTANCE: present invention discloses a spraying device comprising a shell, a spraying core and electrodes. Spraying core includes a heating unit and a liquid transfer unit. Liquid transfer unit includes an air guide part and a base. Air flow chamber is formed between the air guide part and the base. Heating part is located on the inner wall of the air flow chamber and is in contact with the liquid transfer unit. Liquid storage cavity extends to the liquid inlet part of the liquid transfer unit, the air inlet passage communicates with the air inlet opening, and the air outlet passage communicates with the air outlet opening so that when the liquid inlet portion of the liquid transfer unit is in contact with the liquid, liquid is transferred by liquid transfer unit to heating parts for smoke generation, and the external air flow sequentially passes through the air inlet passage, the air inlet opening, the air flow chamber, the air outlet opening and the air outlet passage for removing the smoke from the sprayer.

EFFECT: since the air flow chamber of the spraying core of the spraying device is located in the liquid transfer unit made of porous material, and heating unit heating part is located in air flow chamber, volume, flow rate and air flow trajectory are mainly determined by the design of the liquid transfer unit and do not depend on the interconnection of other parts and the spraying device assembly, which contributes to providing a good and uniform spraying effect in the spraying device.
