Problems solved by technology

However, in order to meet the portable requirements, it is impossible for the electric smoking system to use large-size and large-capacity batteries for power supply, and the battery capacity it uses is generally below 3000mAh (mAh, the unit of measurement for battery capacity), which severely restricts The effective working time of the electric smoking system is reduced, which makes it difficult for the electric smoking system to achieve the ideal working life
Further, through research, it is found that because the heat energy generated by the electric smoking system is not completely used to heat the cartridge, a considerable part of the heat energy escapes to other components of the electric smoking system, which seriously reduces the effective utilization efficiency of the electric heat of the battery. , so it is necessary to reuse part of the escaped heat to improve the working life of the electric smoking system

Embodiment 1

[0033]Such asFigure 1~3 As shown, the heater isolation jacket proposed in the first embodiment includes a heat transfer body 1, a cooling body 2 and a thermoelectric conversion part 3. Among them, the heat transfer body 1 (inner sleeve) is used to be sheathed outside the heater 4 and can uniformly absorb the heat energy escaping from the heater 4. The cooling body 2 (outer sleeve) is sleeved on the outside of the heat transfer body 1 at intervals. The thermoelectric conversion part 3 is provided in the circumferential interlayer between the heat transfer body 1 and the cooling body 2. The thermoelectric conversion part 3 includes a hot end 31 and a cold end 32. The hot end 31 of the thermoelectric conversion part 3 is used to be set in a high temperature area, and the cold end 32 of the thermoelectric conversion part 3 is used to be set in a low temperature area. 31 is in close contact with the heat transfer body 1, and the cold end 32 of the thermoelectric conversion part 3 is in c...

Embodiment 2

[0048]On the basis of the first embodiment above, such asFigure 4~6 As shown, the heater isolation sleeve proposed in the second embodiment is different from the first embodiment in that the heat transfer body 1 is arranged in an irregular cylindrical structure and extends to the periphery on the side wall of the heat transfer body 1. Out of the platform portion 11 can facilitate the bonding of the hot end 31 of the thermoelectric conversion portion 3 with the platform portion 11. The thermoelectric conversion part 3 is provided in a flat plate pattern (plate structure). The hot end 31 of the thermoelectric conversion part 3 is in close contact with the end surface of the platform part 11, and the cold end of the thermoelectric conversion part 3 is in close contact with the inner wall of the cooling body 2. At this time, the heat transfer body 1, the cooling body 2 and the thermoelectric conversion part 3 form a heater isolation jacket that is a combination of nesting and mounting. ...

Abstract

The invention discloses a heater isolation sleeve and an electric smoking system with the heater isolation sleeve. The heater isolation sleeve comprises a heat transfer body, a cooling body and a thermoelectric conversion part, the heat transfer body is used for sleeving the heater; the cooling bodies are arranged outside the heat transfer body at intervals; the thermoelectric conversion part is arranged in an interlayer between the heat transfer body and the cooling body and comprises a hot end and a cold end, the hot end of the thermoelectric conversion part is used for being arranged in a high-temperature area, the cold end of the thermoelectric conversion part is used for being arranged in a low-temperature area, the hot end of the thermoelectric conversion part makes contact with theheat transfer body, and the cold end of the thermoelectric conversion part makes contact with the cooling body. Therefore, the temperature of the hot end of the thermoelectric conversion part is higher than that of the cold end of the thermoelectric conversion part, and then electromotive force is generated between the hot end of the thermoelectric conversion part and the cold end of the thermoelectric conversion part. The electric smoking system comprises a heater, a battery part and a heater isolation sleeve, and the heater isolation sleeve is arranged outside the heater in a sleeving mode and electrically connected with the battery part.

Description

Technical field[0001]The invention relates to a heater isolation sleeve and an electric smoking system with the heater isolation sleeve, belonging to the technical field of low-temperature cigarettes.Background technique[0002]At present, the use of heating instead of burning to process tobacco materials to produce flavor smoke similar to traditional cigarettes is a relatively low-hazard and popular product strategy. Patent CN101277623A discloses an electric smoking system, which includes a tobacco block and belongs to a typical simulated smoking device. Among them, the tobacco block is heated to a temperature in the range of about 150°C (degrees Celsius) to about 220°C to release flavor smoke. The heater adopts an outer shell, an inner rod or plate, and the heater can be arranged in fluid communication with the tobacco block to The aerosol is derived from the system. However, in order to meet the requirements of portability, the electric smoking system cannot be powered by a large-s...
