The fuel gas in the fuel chamber 202 can be discharged from the air holes (not shown) of the adjusting member 30, and the air holes can be uniformly or irregularly arranged, such as honeycomb. In the initial state, the lower end of the air guide rod 20 abuts against the adjusting piece 30 to block the plurality of air holes. When the rotating member 40 drives the air guide rod 20 to be far away from the adjusting member 30, the plurality of air holes on the adjusting member 30 are gradually opened until the lower end of the air guide rod 20 is separated from the adjusting member 30, and the plurality of air holes are changed from the blocking state to the opening state, so that the fuel amount flowing to the air holes in the fuel chamber 201 is gradually increased.

The rotating member 40 is coaxially matched with the air guide rod 20, and the rotation is convenient.
In addition, during manufacturing, the gas flow rate at which the cartridge can be heated to the preferred temperature most quickly and stably and the temperature of the combustion chamber 202 in the steady state can be calibrated by testing so that the temperature of the fuel flow regulator 100 in the steady state is the preferred temperature for heating the cartridge (no longer continues to rise).
The fuel flow regulating device 100 of the present invention comprises a housing 10, an air guide rod 20, a regulating member 30 and a rotating member 40, wherein the housing 10 is provided with an accommodating cavity 11 communicated with a fuel chamber 202, the air guide rod 20 and the regulating member 30 are both arranged in the accommodating cavity 11, the regulating member 30 is arranged between the air guide rod 20 and the fuel chamber 202, and a plurality of air holes are arranged. When the user smokes and heats the non-combustion type tobacco product 1000, because the convection heat exchange can take away a part of heat, make the cartridge temperature in the cartridge chamber 201 drop, original steady state balance is broken, if the user needs to continue to smoke this moment, then need be through increasing fuel flow in order to shorten the temperature compensation time, at this moment, the user can be independently through rotating the rotation piece 40, make the rotation piece 40 drive the air guide rod 20 and keep away from the regulating part 30, in order to open a plurality of bleeder vents, make the fuel that flows to the venthole 20b from the inlet port 20a increase, the fuel velocity of flow has been increased promptly. When the rotating member 40 drives the air guide rod 20 to approach the adjusting member 30, so as to block the plurality of air holes, the fuel flowing from the air inlet hole 20a to the air outlet hole 20b is reduced, i.e. the fuel flow rate is reduced, thereby facilitating the continuous suction of the user.
