Description

Low use cost's two cigarette shells heat incombustible smoking set

Technical Field

The utility model relates to the technical field of heating non-combustible cigarettes, in particular to a double-cartridge heating non-combustible smoking set with low use cost.

Background

The cigarette is heated without combustion, which is not required to be ignited like the traditional cigarette, but the tobacco is precisely heated by a temperature control technology to reach the temperature which just releases aromatic substances and nicotine contained in the tobacco, so as to form smoke. Heating tobacco instead of lighting tobacco is not only a technical revolution, but is also key to achieving harm reduction, as most carcinogens and toxic compounds are formed during the combustion process during smoking. The mouth feel of smoke generated by heating a non-combustible cigarette is similar to that of the smoke generated by a traditional cigarette, so that the cigarette is more and more accepted by many smokers.

In order to enable smokers to experience more smell or effect, some heating non-combustible cigarettes with explosion beads appear in the market at present, wherein a small liquid rubber bead is embedded in a cigarette filter rod, namely the explosion beads for cigarettes, and the explosion beads for cigarettes can wrap different types of liquid spices; in general, when the bead blasting for cigarettes is produced, the bead blasting for cigarettes is added into a filter stick which heats non-combustible cigarettes in an online manner, and then the cigarette product containing the bead blasting for cigarettes is formed through rolling and forming. When the cigarette is used, a smoker can break the bead for the cigarette to release the liquid fragrance releasing substance in the bead, and the liquid fragrance releasing substance in the bead is taken away by heating the aerosol smoke which is released to flow during smoking, so that the smoker can experience various smells or efficacies given by the bead for the cigarette. However, the mode of adding the popping beads into the filter stick has difficulty in processing the filter stick, and a sucker cannot select the popping beads with different tastes according to the preference, so that the suction pleasure and experience of the sucker are poor.

The smoking set needs to be used when the cigarette is smoked and smoked by heating and non-combustible burning, the existing product which is directly added with the blasting beads is less, the shell of the blasting beads is mainly prepared by adopting a gelatin material, and after the smoking set is placed in the smoking set and used for a long time, the gelatin which is melted by the blasting beads can block a cooling mechanism in the smoking set, so that the smoking set cannot be used, and the use cost of the smoking set of a smoker can be increased.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims to provide a double-cartridge heating non-combustion smoking set with low use cost, which can add bead blasting in the smoking set to increase the smoking pleasure and experience of smokers; and when the cooling mechanism is blocked, only the cooling mechanism can be replaced, so that the use cost of the smoking set is lower.

The utility model solves the technical problems by the following technical means:

a low-use-cost double-cartridge heating non-combustion smoking set comprises a smoking set cover, a cartridge heating device and a power chip device which are sequentially connected, wherein a cooling accommodating section is arranged at one end, close to the cartridge heating device, of the smoking set cover, a filter tip through hole communicated with the cooling accommodating section is formed in the smoking set cover, a first cartridge cavity and a second cartridge cavity which are mutually communicated are formed in the other end of the cooling accommodating section, a first heating cavity and a second heating cavity are formed in the cartridge heating device, an air flow channel is arranged between the first heating cavity and the cooling accommodating section and between the second heating cavity and the cooling accommodating section, a first heating core is arranged at the bottom of the first heating cavity, a second heating core is arranged at the bottom of the second heating cavity, the cooling accommodating section comprises a cooling barrel, and a first air vent communicated with the filter tip through hole is formed in one end of the cooling barrel; a disc is fixedly connected in the cooling cylinder, a plurality of vent pipes vertically penetrating through the disc are arranged on the disc, one end of each vent pipe is communicated with the first vent hole, and a bead blasting cavity is arranged between the other end of each vent pipe and the cooling cylinder; one ends of the first cigarette bullet cavity and the second cigarette bullet cavity, which are far away from the cooling cylinder, are respectively provided with a first heating core hole and a second heating core hole; a connecting cylinder is arranged at one end, close to the smoke cartridge heating device, of the smoking set cover, an internal thread is arranged on the inner wall of the connecting cylinder, an external thread is arranged at one end of the cooling cylinder, first through holes are formed in two sides of the other end of the cooling cylinder, a sliding block is arranged in each first through hole in a sliding mode, a spring is fixedly connected to one end, located in the bead blasting cavity, of each sliding block, a fixed block is fixedly connected to one end, away from the sliding block, of each spring, and the fixed block is fixedly connected with the bottom of the connecting cylinder; the end parts of the first cigarette bullet cavity and the second cigarette bullet cavity, which are close to the cooling cylinder, are provided with fixed cylinders, and the two sides of each fixed cylinder are provided with second through holes matched with the first through holes.

Furthermore, a first air inlet hole is formed in the side wall, located in the bead explosion cavity, of the cooling cylinder, a second air vent is formed between the bead explosion cavity and the first smoke bomb cavity, an air inlet pipe is communicated with the first air inlet hole, and the air inlet pipe penetrates through the bead explosion cavity and is communicated with the second smoke bomb cavity; the cigarette bullet heating device is provided with the second inlet port with second heating chamber intercommunication, first inlet port and second inlet port cooperation setting.
