The utility model provides a fuel flow adjusting device 100 for heat non-combustion type tobacco products 1000.

Referring to fig. 1, 3, 4 and 6, in an embodiment of the present invention, the fuel flow adjusting device 100 includes:

a housing 10 provided in the body 200, the housing 10 having a housing chamber 11 communicating with the fuel chamber 202;

the air guide rod 20 is arranged in the accommodating cavity 11, the air guide rod 20 is provided with an air inlet hole 20a communicated with the accommodating cavity 11 and an air outlet hole 20b communicated with the smoke and bomb cavity 201, and the air inlet hole 20a is communicated with the air outlet hole 20 b;

the adjusting piece 30 is arranged in the accommodating cavity 11 and positioned between the air guide rod 20 and the fuel chamber 202, and the adjusting piece 30 is provided with a plurality of air holes for communicating the accommodating cavity 11 with the fuel chamber 202; and

the rotating piece 40 is connected with the air guide rod 20 and can rotate relative to the shell 10, and the rotating piece 40 drives the air guide rod 20 to be far away from the adjusting piece 30 so as to open the plurality of air holes; 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.

Specifically, the fuel chamber 201 is a chamber for storing fuel, the fuel is mainly gas, such as butane, a gas tank for storing or replacing fuel can be further arranged in the combustion chamber 201, and when the fuel in the fuel chamber 202 is used up or is insufficient, the fuel in the fuel chamber 202 can be replenished at any time. The cartridge chamber 201 is the chamber in which the cartridges are placed and replaced and in which ignition of the cartridges and combustion of the cartridges are accomplished. The body 200 is made of a high temperature resistant material, such as glass, ceramic or metal, near the combustion chamber 202 to prevent high temperature damage.

The housing 10, the gas guide rod 20 and the rotating member 40 are made of materials with low thermal conductivity and high temperature resistance, such as stainless steel, ceramic, glass or high temperature plastics, for example, PEI (Polyetherimide) resin, so as to reduce the heat conduction loss of the combustion chamber 202 to the smoke chamber 201 and improve the safety performance.

The adjusting member 30 is made of a porous elastic material, such as an elastic plastic having a plurality of openings, and the adjusting member 30 also has a certain buffering effect on the lower end of the air guide rod 20. 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. When the rotating member 40 rotates reversely to drive the air guide rod 20 to be close to the adjusting member 30, the plurality of air holes on the adjusting member 30 are gradually blocked until the lower end of the air guide rod 20 abuts against the adjusting member 30, and the plurality of air holes are changed from the open state to the blocking state, so that the fuel quantity flowing to the air holes in the fuel chamber 201 is gradually reduced. Thus, the flow rate of the fuel flowing through the plurality of vent holes can be conveniently adjusted, and the flow rate of the fuel flowing from the inlet hole 20a to the outlet hole 20b is increased.
