Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heated cigarettes, in particular to a heated cigarette and a heating appliance. BACKGROUND

[0002] The peripheral heating type heated cigarette has a higher heating area than the common needle heating, and thus can realize a higher sheet utilization rate. However, the existing peripheral heating method directly heats the composite aluminum foil paper wrapping the heated cigarette in the cavity of the appliance, and the base paper directly contacts the high-temperature heat source, which causes an uncomfortable "paper taste" during the smoking process of the peripheral heating cigarette.

[0003] In addition, the existing aluminum foil composite paper used for the heated cigarette has poor resilience, and thus the appearance is not good due to the deformation of the end. SUMMARY

[0004] To solve the above technical problems, the present application provides a heated cigarette and a heating appliance, which can effectively solve the problems of "paper taste" during the smoking process of the peripheral heating type heated cigarette and the easy deformation of the end of the heated cigarette.

[0005] The technical scheme provided by the present application is as follows:

[0006] A heated cigarette comprises a conductive metal ring, a smoking segment, a conductive heating composite paper and a cigarette mouthpiece rod, the first and last ends of the smoking segment are connected with the conductive metal ring and the cigarette mouthpiece rod in sequence, and the conductive metal ring and the smoking segment are wrapped in the conductive heating composite paper by conductive glue.

[0007] Preferably, the smoking segment is connected with an O rod of the cigarette mouthpiece rod, and the smoking segment and the O rod are both provided with a shaped paper outside.

[0008] Preferably, the other end of the O rod is connected with a binary composite filter rod, and the O rod and the binary composite filter rod are covered with a tipping paper outside.

[0009] Preferably, the conductive heating composite paper comprises, from outside to inside, a base paper, a temperature-lowering and heat-insulating material layer and an electrocaloric heating material coating.

[0010] Preferably, the thermal conductivity coefficient of the temperature-lowering and heat-insulating material layer is 0.01-1 w / (m·K), and the electrical conductivity of the electrocaloric heating material coating is 1000-50000 s / m.

[0012] Preferably, the smoking segment comprises an atomized sheet or a combination of an aluminum foil and an atomized sheet.

[0013] A heating appliance for heating the heating cigarette described above, comprising an appliance body, a cavity for accommodating the heating cigarette and a power supply assembly for heating the heating cigarette are arranged in the appliance body, and the bottom surface of one end of the cavity is in contact with the conductive metal ring of the heating cigarette.

[0015] Preferably, the magnetic unit comprises a permanent magnet or an electromagnet.

[0016] The present application has the following advantages over the prior art:

[0017] 1.

DETAILED DESCRIPTION

[0026] In order for those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0027] As shown in Figure 1 , the present embodiment provides a heating cigarette, which comprises electrically conductive heating composite paper 1, a smoking segment 2, an electrically conductive metal ring 3 (a thin-walled metal cylinder), and a cigarette mouthpiece rod. The smoking segment 2 is sequentially connected with the electrically conductive metal ring 3 and the cigarette mouthpiece rod at the head and tail, respectively. The electrically conductive metal ring 3 and the smoking segment 2 are wrapped and connected in the electrically conductive heating composite paper 1 by means of electrically conductive glue. The smoking segment 2 and the electrically conductive metal ring 3 form an electrically conductive smoking segment through the wrapping and connection of the electrically conductive heating composite paper 1. The O rod 4 of the smoking segment 2 and the cigarette mouthpiece rod is connected, and the smoking segment 2 and the O rod 4 are both externally provided with shaped paper 5. The other end of the O rod 4 is connected with a binary composite filter rod 6. The O rod and the binary composite filter rod 6 are externally covered with tipping paper 7.

[0028] As shown in Figure 3 , in the present embodiment, the electrically conductive heating composite paper 1 comprises, from the outside to the inside, a base paper 11, a temperature-reducing and heat-insulating material layer 12, and an electrically conductive heating material coating 13. The thermal conductivity of the temperature-reducing and heat-insulating material 12 is 0.01-1 w / (m·K), and the electrical conductivity of the electrically conductive heating material coating 13 is 1000-50000 s / m. The material composition of the temperature-reducing and heat-insulating material layer 12 includes one or a combination of several of polylactic acid, modified polylactic acid, polyvinylpyrrolidone, and polydimethylsiloxane; and the material composition of the electrically conductive heating material coating 13 includes one or a combination of several of carbon-based material, metal oxide ceramic material, and metal alloy material. The carbon-based material includes one or a combination of several of graphite, carbon fiber, carbon nanotube, and carbon black; the metal oxide ceramic material includes one or a combination of several of iron oxide, tungsten oxide, chromium oxide, and aluminum oxide; and the metal alloy material includes one or a combination of several of iron-chromium-aluminum alloy, iron-chromium-aluminum-lithium alloy, nickel-chromium alloy, and tungsten-manganese alloy.

[0029] In this embodiment, the smoke-generating section 2 includes a combination of aluminum foil 22 and atomizing sheet 21 (tobacco sheet), which is wrapped with thick aluminum foil with good resilience. The aluminum foil can conduct heat and fix the smoke-generating section 2. In other embodiments, the smoke-generating section 2 may only include atomizing sheet 21.

[0030] In this embodiment, the manufacturing process of heated cigarette is as follows: (1) Pure aluminum foil paper 22 without base paper and atomizing sheet 21 form a smoke-generating section 2; (2) Smoke-generating section 25 and conductive metal ring 3 are rolled together by conductive heating composite paper 1 to form a conductive smoke-generating section; (3) Conductive smoke-generating section and O rod 4 are combined by forming paper 5 to form a composite section; (4) Composite section and binary composite filter rod 6 are combined by attaching paper 7 to form a complete heated cigarette stick.

[0031] like Figure 2 As shown, a heating device for heating the aforementioned heated cigarette includes a device body 8. The device body 8 contains a cavity 81 for accommodating the heated cigarette and a power supply component for heating the cigarette. One bottom surface of the cavity 81 contacts the conductive metal ring 3 of the heated cigarette. The bottom surface of the cavity 81 at the contact end is made of a conductive metal material. When the conductive metal ring 3 at the end of the heated cigarette contacts it, a conductive path is formed from the device body 8 to the electrothermal material coating 13. Power is supplied by the power supply component (generally a battery) built into the device body 8 to heat the tobacco segment 2. A magnetic unit 82 is provided on the outer side of the bottom surface of the cavity. The magnetic unit 82 includes an electromagnet. When the heating function is activated, it generates a strong magnet through electromagnetic induction, which firmly attracts the end of the heated cigarette to the bottom surface of the cavity 81 of the device body 8, thus greatly avoiding contact resistance. When the heated cigarette is finished being inhaled, the electromagnetic induction module automatically de-energizes, and the magnetism disappears, releasing the heated cigarette. The heated cigarette can then be easily pulled out of the device. By using electromagnetic induction to fix and release the heated cigarette, insertion and removal resistance can be completely avoided. In other embodiments, the magnetic unit 82 can also be a structure including a permanent magnet. After the conductive metal ring 3 at the end of the heated cigarette comes into contact with the permanent magnet, it can be attracted to the bottom surface to form a conductive path, similar to the magnetic attraction charging effect in a Bluetooth headset charging case.

[0032] In this embodiment, the inner diameter of the cavity 81 and the outer diameter of the heated cigarette form a heating cavity, and the width of the heating cavity is not less than 0.5 mm. Since the heated cigarette is fixed in the cavity 81 by the magnetic attraction force generated by electromagnetic induction at the bottom, the inner diameter of the heating cavity can be appropriately enlarged relative to the outer diameter of the heated cigarette, which can completely avoid the resistance that may be generated during the insertion and removal of the heated cigarette.

[0033] The foregoing description of the disclosed embodiments enables a person skilled in the art to make or use the application. Modifications of these embodiments will occur to persons of skill in the art, and that the appended claims are intended to cover all such modifications that do not depart from the true spirit and scope of the application. Therefore, the application is not limited to the embodiments shown but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
