SEPARATE GAS SUPPLY DEVICE FOR A SMOKING APPLIANCE Russian patent published in 2019 - IPC A24F47/00 

FIELD: smoking accessories.

SUBSTANCE: invention relates to the field of electronic cigarettes, and, in particular, it relates to the device for separate gas supply of the smoking device. Device for separate gas inlet of smoking device comprises microphone (2), which is a cylindrical air flow sensor, open at both ends; microphone base (3), generally made in the form of a cylinder open at both ends, wherein in the cylinder there is microphone hole (301), to which the outer wall of said microphone (2) is tightly attached; at one end of said microphone base (3) perpendicular to its wall there is U-shaped channel (302) for passing gas to microphone, communicating inner part of cylinder with outer, and at that end wall is provided with outer slot (305) of wall; along the outer wall of the cylinder in the axial direction there are two slots, one of which is the first fixing guide slot (303), and the other is the gas passage channel (304) from the cigarette; transparent base (4), generally made in form of cylinder, closed in middle part; along cylinder outer wall on inner side in axial direction second locking guide groove (401) is made; at one end of said transparent base (4) perpendicular to wall there is U-shaped slot (403) for gas passage to microphone communicating inner part of cylinder with outer; and at that end protruding convex wall (404) is provided for connection with microphone base, tightly adjacent to said outer wall slot (305); closed middle part in the cylinder is microphone hole plug (402); between said microphone opening plug (402) and the cylinder wall, a first cigarette gas outlet (405) communicating with the said gas passage channel (304) from the cigarette; filtering fixing base (5), generally made in the form of a cylinder closed at one end, at that the closed end contains several small holes, which are second holes (502) for gas from the cigarette, from the closed end in the axial direction passes the fixing guide ledge (501), which with tight fit is inserted into said first fixing guide groove (303) and said second fixing guide groove (401); said filtering fixing base (5) is hermetically inserted into free end transparent base (4); said microphone base (3) and said transparent base (4) are connected to a tight fit; wherein said second holes (502) for gas from cigarette by means of gap between said filtering fixing base (5) and transparent base (4) are made in communication with said first hole (405) for gas from cigarette and said channel (304) for passage gas from cigarette in said microphone base (3); insulating fastening bushing (6), generally made in the form of a cylinder and tightly embracing said filtering fixing base (5); charging sleeve (7), generally made in the form of a cylinder and in the upper part of the tightly enclosing the said insulating fastening bushing (6), with the lower part inserted into tube (1) with the suction hole, and in middle part equipped with several gas guide holes (71) made in communication with said slot (403) for gas passage to microphone and said channel (302) for gas passage to microphone; wherein air from said gas guide holes (71) extends into said gas passage channel (403) to microphone and said channel (302) for passing gas to microphone, then passes into said microphone (2), resulting in bringing electronic cigarette in action; wherein smoke from said second holes (502) for gas from cigarette passes into gap between said filtering fixing base (5) and transparent base (4), passes into said first hole (405) for gas from cigarette, then passes into said channel (304) for passage of gas from cigarette, after which passes into tube (1) with suction hole.

EFFECT: preventing the traditional cigarettes resin attachment to the gas inlet holes in the microphone, leading to its failure, and increasing the service life on which the electronic cigarette smoking appliance is designed.
