ELECTRONIC CIGARETTE SPRAY UNIT WITH CIRCULAR AIR CHANNEL AND ELECTRONIC CIGARETTE SPRAY ASSEMBLY Russian patent published in 2023 - IPC A24F40/46 

FIELD: smoking products.

SUBSTANCE: group of inventions is related to a spray unit of an electronic cigarette with a circumferential air channel and to a spray unit of an electronic cigarette. The spray unit of an electronic cigarette with a circumferential air channel comprises a base, an outer cover, a liquid-conducting element, a containing cavity, a support element, and a heating element. A first air hole is formed in the lower surface of the base, and a second air hole is formed in its upper surface, and the first air hole communicates with the second air hole. The outer cover is located on the base. The third air hole is formed in the outer cover. The fluid-conducting element is located in the outer cover. The containing cavity extends through two sides of the fluid-conducting element and is formed in the fluid-conducting element. The supporting element is located in the containing cavity. A groove is formed on the outer side of the support element, and the second air hole faces the lower surface of the support element. The heating element is located in the containing cavity and placed between the fluid-conducting element and the support element. The support element supports the heating element configured to be attached to the inside of the fluid-conducting element, and the fluid-conducting element is configured to conduct liquid to the heating element. The heating element closes the groove of the support element so that the groove and the heating element form a ventilation channel which communicates with the third air hole. At least a portion of the lower surface of the support member and the base form an air space that allows the second air hole to communicate with the ventilation duct so that the air flow sequentially passes through the first air hole, the second air hole, the air space, the ventilation duct and the third air hole.

EFFECT: eliminating leakage of liquid entering the air channel and the formation of condensate in the air channel.
