Abstract
Description
- The invention relates to cigarette substitutes, and specifically to a baked smoking set, a heating element thereof and a method for manufacturing the heating element.
- During high temperature combustion, traditional tobaccos release many noxious substances for human body. Recently, in order to reduce noxious substances produced in high temperature combustion, a low temperature baked smoking set for heating tobaccos without combustion appears, and there are two heating manners defined as peripheral heating and central heating.
- As for a heating element used in central heating, by inserting the heating element into the cigarette, the common structure is to fix a heating element onto a base, and insert the heating element into the tobacco product to heat and atomize surrounding tobaccos.
- The heating element used in current low temperature cigarette smoking set is usually formed by printing a heating track on a long-strip-shaped flat base material in a manner of printing circuits and the like. During inserting and pulling several times, the long-strip-shaped heating element is fractured or deformed due to insufficient strength, such that the heating track floats on the heating element to form a virtual connection, and affect the atomization effect.
- The technical problem to be solved by the invention is to provide an improved baked smoking set, a heating element thereof and a method for manufacturing the heating element.
- The technical solution of the invention adopted for solving the technical problem is to construct a heating element of a baked smoking set, comprising a sheet-shaped main substrate, wherein;
the main substrate comprises an insertion end and a connection end at two opposite ends, and the insertion end is configured to be inserted into a cigarette;
reinforced members are provided by extending outwardly from two lateral sides between the connection end and the insertion end to improve strength of the main substrate, and prevent the main substrate from bending. - Preferably, the reinforced members on the two lateral sides are located on the same side or different sides of the main substrate, respectively.
- Preferably, the main substrate is in a long strip shape.
- Preferably, the insertion end is a sharp end.
- Preferably, the reinforced member is in a sheet or strip shape.
- Preferably, a width of the reinforced member gradually increases from one end close to the insertion end to a direction away from the insertion end of the heating element.
- Preferably, a lateral surface of the reinforced member forms a slope at an angle with the insertion end of the main substrate.
- Preferably, a heating track is provided on a surface of the main substrate.
- Preferably, the main substrate and the reinforced member are integrally formed.
- The invention further provides a method for manufacturing the heating element of a baked smoking set, comprising the steps of:
- punching a plate-shaped base material made of a metallic material to form a sheet-shaped heating substrate;
- bending the heating substrate to form a heating base material, the heating base material comprising a sheet-shaped main substrate and reinforced members provided by extending outwardly from two lateral sides of the main substrate; and
- printing a heating track on the main substrate.
- Preferably, a set of upper die and lower die are provided, wherein the upper die and the lower die are provided with a punching station and a forming station, respectively;
the punching station is used for punching the plate-shaped base material to form the sheet-shaped heating substrate; and
the forming station is used for bending the heating substrate to form the heating base material. - The invention further provides a baked smoking set, comprising the heating element.
- Implementing the baked smoking set, the heating element thereof and the method for manufacturing the heating element of the invention has the following advantageous effects: the reinforced member is configured to strengthen the main substrate, which effectively reduces virtual connection or floating of the heating track due to deformation or fracture of the heating element during inserting and pulling of tobaccos, and optimizes the atomization effect. Meanwhile, the reinforced member increases a heating area of tobaccos, so as to heat and atomize tobaccos more uniformly, and improve taste of tobaccos.
- Hereinafter, the invention is further described with reference to accompanying drawings and embodiments. In the drawings:
-
FIG. 1 is a structural diagram of reinforced members of a heating element when disposed on the same side of the main substrate in one embodiment of the invention. -
FIG. 2 is a schematic diagram of the heating element along an end face direction inFIG. 1 . -
FIG. 3 is a structural diagram of reinforced members of a heating element when disposed on different sides of the main substrate in one embodiment of the invention. -
FIG. 4 is a schematic diagram of the heating element along an end face direction inFIG. 3 . -
FIG. 5 is a schematic diagram of an upper die and a lower die forming the main substrate and the reinforced members. - To clearly understand technical features, objects and effects of the invention, now detailed embodiments of the invention are explicitly explained with reference to the accompanying drawings.
- A baked smoking set in one preferable embodiment of the invention comprises a cavity for insertion of a cigarette, and a
heating element 1 disposed within the cavity. When the cigarette is inserted into the cavity, theheating element 1 is also inserted into the cigarette, and after being powered and temperature rising, theheating element 1 bakes and heats the cigarette, and heats and atomizes surrounding tobaccos. In other embodiments, the cigarette can be inserted into the cavity firstly, and then theheating element 1 is inserted into the cigarette. - As shown in
FIGS. 1 and 2 , theheating element 1 comprises a sheet-shapedmain substrate 11. Themain substrate 11 comprises an insertion end A and a connection end B at two opposite ends, theheating element 1 is inserted into a cigarette by the insertion end A, and the connection end B is fixed onto a heating base or a bottom of the cavity. Preferably, the insertion end A is a sharp end to facilitate inserting into the cigarette. In other embodiments, the insertion end A also can be an arc side or an inclined side. - Reinforced
members 12 are provided by extending outwardly from two lateral sides between the connection end B and the insertion end A to improve strength of themain substrate 11, and prevent themain substrate 11 from bending. Generally, aheating track 13 is provided on a surface of themain substrate 11, and after connected to a power supply, theheating track 13 generates heat and transmits the heat to themain substrate 11 and the reinforcedmembers 12, so as to heat and atomize surrounding tobaccos. - The reinforced
member 12 is configured to strengthen themain substrate 11, which effectively reduces virtual connection or floating of theheating track 13 due to deformation or fracture of theheating element 1 during inserting and pulling of tobaccos, and optimizes the atomization effect. Meanwhile, the reinforcedmember 12 increases a heating area of tobaccos, so as to heat and atomize tobaccos more uniformly, and improve taste of tobaccos. - In some embodiments, the
main substrate 11 is in a long strip shape. Themain substrate 11 may also be a conical plate or a triangular plate with a gradually variable width, which can facilitate inserting into the cigarette. Themain substrate 11 also may be a long-strip-shaped plate with an arc-shaped fracture surface. - The reinforced
members 12 on the two lateral sides are located on the same side of themain substrate 11, respectively. Generally, the reinforcedmember 12 is in a sheet shape, and is formed by bending towards the same side of themain substrate 11. In other embodiments, it also can be formed by welding onto themain substrate 11. An angle between the reinforcedmember 12 and themain substrate 11 may be a right angle, and also may be an obtuse angle, only if it facilitates bending. As shown inFIGS. 3 and 4 , in other embodiments, the reinforcedmembers 12 on the two lateral sides also can be located on different sides of themain substrate 11, respectively. - In other embodiments, the reinforced
member 12 also may be in a strip shape, and has a relatively low protruded height by extending outside themain substrate 11, only if strength can be ensured. Position of the strip-shaped reinforcedmember 12, and the angle with themain substrate 11 can be the same as that of the sheet-shaped reinforcedmember 12. - In order to facilitate insertion of the reinforced
member 12 into the cigarette, a width of the reinforcedmember 12 gradually increases from one end close to the insertion end A to a direction away from the insertion end A of theheating element 1. On one hand, it saves effort in inserting and pulling the cigarette, and on the other hand, it also can reduce accumulation of tobaccos on lateral surfaces of theheating element 1, so as to avoid forming residual soot. - The reinforced
member 12 gradually varies in width, such that a guidingface 121 in smooth transition with the insertion end A of themain substrate 11 is formed on the lateral surface of the reinforcedmember 12 to function as guidance when the cigarette is inserted. Preferably, the guidingface 121 is a slope at an angle with the insertion end A of themain substrate 11, and the guidingface 121 also may be an arc surface. - In some embodiments, the
main substrate 11 and the reinforcedmember 12 are integrally formed. Preferably, themain substrate 11 and the reinforcedmember 12 are made of metallic materials, and can be produced by simple punching and bending, which is relatively low in production cost. Themain substrate 11 and the reinforcedmember 12 also may be formed by sintering integrally using materials of ceramics, and the like. - When the
main substrate 11 and the reinforcedmember 12 are made of metallic materials, such as, stainless steel, alloy and the like, the method for manufacturing theheating element 1 comprises the steps of: - machining a plate-shaped base material made of a metallic material to form a sheet-shaped heating substrate;
- bending the heating substrate to form a heating base material, the heating base material comprising a sheet-shaped
main substrate 11 and reinforcedmembers 12 provided by extending outwardly from two lateral sides of themain substrate 11; and - printing a
heating track 13 on themain substrate 11. - In some embodiments, machining of the plate-shaped base material made of a metallic material may use die cutting, and also may use wire cut machining.
- As shown in
FIG. 5 , further, in order to improve machining efficiency, a set ofupper die 2 and lower die 3 is provided, and theupper die 2 and the lower die 3 are provided with a punching station (not shown) and a forming station C, respectively;
the punching station is used for punching the plate-shaped base material to form the sheet-shaped heating substrate; and
the forming station C is used for bending the heating substrate to form the heating base material. - It shall be understood that the above respective technical features can be combined optionally for use without limitation.
- The disclosures are only embodiments of the invention, rather than limiting the extent of the invention. Any equivalent structures or equivalent flow changes using the specification and the drawings of the invention, or directly or indirectly application in other relevant technical fields shall also be included in the extent of protection of the invention.
