- As shown in
FIGS. 1 and 2 , a baked smoking set in one preferable embodiment of the invention comprises a tubular sleeve 1, and a heating assembly 2 comprising aheating element 21, a leadingwire 22 and amounting base 23. - Referring to
FIGS. 1-3 , theheating element 21 is in a sheet shape, and is detachably inserted into the sleeve 1. Theheating element 21 comprises a first end A and a second end B opposite to the first end A in a length direction, and the first end A is configured to be inserted into the sleeve 1 of the baked smoking set. - The
heating element 21 comprises a first side C and a second side D opposite to the first side C in a width direction, and the first side C and the second side D are provided with ablade portion 211 respectively that allows a thickness of theheating element 21 to gradually decrease towards an edge in the width direction. A central line of theheating element 21 is coaxial with a center of the sleeve 1, and distances from two opposite sides in the width direction of theheating element 21 to an inner wall surface of the sleeve 1 respectively are equivalent. - Since the two sides of the
heating element 21 become thinner gradually, when theheating element 21 is inserted into a cigarette 3 received in the sleeve 1, pressures of the two sides of theheating element 21 on tobaccos can be reduced, and tobaccos proximal to the two sides corresponding to theblade portions 211 may not be subjected to extrusion or compression, thereby relieving the pressures on tobaccos proximal to the two sides, and improving atomizing efficiency of tobaccos. Theblade portions 211 also can represent a smooth transition, to prevent tobaccos from sticking on the two sides of theheating element 21. - The
heating element 21 comprises a first surface E and a second surface F opposite to the first surface E in a thickness direction, and theblade portions 211 comprises chamfers on edges of the first surface E and the second surface F adjacent to the first side C, and chamfers on the edges of the first surface E and the second surface F adjacent to the second side D. - Each chamfer can be a bevel or a fillet. The edges of the first surface E and the second surface F adjacent to the first side C are respectively provided with the chamfer, and the edges of the first surface E and the second surface F adjacent to the second side D are respectively provided with the chamfer, and the
blade portions 211 of the first side C and the second side D transform the first side C and the second side D of theheating element 21 to round edges or sharp edges. - In other embodiments, the
blade portions 211 may comprise a chamfer only on the edge of the first surface E or the second surface F adjacent to the first side C, and a chamfer only on the edge of the first surface E or the second surface F adjacent to the second side D, to transform the first side C and the second side D to sharp edges, so as to facilitate once punch forming. - Smooth transition, or smooth polishing, or coating a glaze layer of the
blade portions 211 on two opposite sides can effectively prevent sticking of tobaccos on the sides, and relieve accumulation of tobaccos. - As shown in
FIG. 4 , theheating element 21 comprises a sheet-shaped substrate 212 made of a metallic material, aninsulating layer 213 covered on the sheet-shaped substrate 212, and aconductive path 214 disposed outside theinsulating layer 213. The leadingwire 22 is connected to theconductive path 214, and the leadingwire 22 is led outwardly. Theconductive path 214 can be supplied with power through the leadingwire 22, so that theconductive path 214 generates heat to atomize tobaccos. - Preferably, the
heating element 21 is made of a metallic or an alloy material, and the sheet-shaped substrate 212 may use metallic materials, such as stainless steel or titanium alloy, preferably stainless steel, such as 430 and 304 stainless steel. A thickness of the sheet-shaped substrate 212 is generally 0.2 to 0.8 mm, and the sheet-shaped substrate 212 is formed by punch forming or wire cutting, which is low in cost. Theblade portions 211 on the sheet-shaped substrate 212 made of a metallic material can be formed by punching to further save cost. Dimensions of length, width and the like of theheating element 21 are fitted with diameter and length of the cigarette, which facilitates sufficient heating of tobaccos. - The sheet-
shaped substrate 212 made of a metallic material, as a main body of theheating element 21, has a high toughness, so that fracture of theheating element 21 can be effectively prevented under long-term high temperature and mechanical shock, such as, cigarette loading, and the like. Meanwhile, the sheet-shaped substrate 212 made of a metallic material has a good thermal conductive performance, which ensures uniformity of a surface temperature of theheating element 21, and facilitates heating the non-combustible cigarette to obtain an optimized taste. - Referring to
FIGS. 5 and7 , according to steady state simulation experiments, in the same temperature fields, the area exceeding 215 degrees Celsius around theheating element 21 made of stainless steel is larger than that around theheating element 21 made of ceramic such as zirconium oxide and the like, so the atomizing efficiency of theheating element 21 made of stainless steel is higher, and taste is better. - Preferably, the first end A of the sheet-
shaped substrate 212 is provided with asharp head 215 that facilitates inserting into a cigarette 3. Thesharp head 215 can guide insertion of theheating element 21, and reduce a resistant force when inserting. - In order to satisfy process requirements for printing the
conductive path 214 onto the sheet-shaped substrate 212, the sheet-shaped substrate 212 comprises a flat surface 2121 between theblade portions 211 on the two opposite sides of theheating element 21, and theconductive path 214 is printed in an area of the flat surface 2121. Theblade portions 211 are disposed outwardly by two opposite sides in a width direction of the flat surface 2121. - The
insulating layer 213 is formed by sintering at 400 to 1000 °C after a surface of the sheet-shaped substrate 212 is covered by a glass slurry containing silicon oxide, calcium oxide, and aluminum oxide, and since the sheet-shaped substrate 212 made of a metallic or an alloy material is conductive, theinsulating layer 213 can prevent a short circuit between the sheet-shaped substrate 212 and theconductive path 214. - The
insulating layer 213 is covered on the sheet-shaped substrate 212 by the way of spraying or printing, and a thickness of theinsulating layer 213 can be designed according to pressure resistance requirements between theconductive path 214 and the sheet-shaped substrate 212. Generally, the insulatinglayer 213 has a thickness less than 0.1 mm. - In order to prevent oxidation of the sheet-shaped
substrate 212 made of a metallic material during use in a high temperature, preferably, two sides of the sheet-shapedsubstrate 212 are covered with the insulatinglayer 213. Theconductive path 214 is located on one side of the insulatinglayer 213. The insulatinglayer 213 also can be provided only on one side of the sheet-shapedsubstrate 212 which theconductive path 214 is disposed, and when theheating element 21 is made of a non-metallic and non-conductive material, the insulatinglayer 213 also can be removed. - The
conductive path 214, as a resistance heater, can be a conductive layer formed on the insulatinglayer 213 in a manner of such as physical vapor deposition, or electroplating, or printing. - Preferably, the
conductive path 214 comprises aheating resistor 2141, and an electrical connection portion electrically connected to theheating resistor 2141. Theheating resistor 2141 and the electrical connection portion are arranged along a length direction of the sheet-shapedsubstrate 212, andconductive electrodes 2142 are connected to an external circuit. Preferably, the electrical connection portion comprises twoconductive electrodes 2142 electrically connected to theheating resistor 2141. - The leading
wires 22 are connected to theconductive electrodes 2142, and are led out from one end away from theheating resistor 2141 along a length direction of theheating element 21, i.e., theheating resistor 2141 and theconductive electrodes 2142 are arranged in a direction from the first end A to the second end B, and the leadingwires 22 are led outwardly from the second end B. - The
heating resistor 2141 can be formed by sintering after printing with any one of silver-palladium resistance slurry, ruthenium-palladium resistance slurry, platinum slurry and nickel-based slurry. Theheating resistor 2141 can be flexibly patterned, and an appropriate resistance value desired for theheating element 21 is obtained in cooperation with the slurry properties and a thickness of theheating resistor 2141. The resistance value of theheating element 21 is usually between 0.3 to 2.0 Ω, and the thickness of theheating resistor 2141 is usually less than 0.1mm, preferably, less than 20 1µm. Theconductive electrode 2142 is formed by sintering after printing with silver-based slurry having a relatively low resistivity. - When the leading
wire 22 is connected to an external power supply, theheating resistor 2141 can be powered to generate heat, and the leadingwire 22 can be connected to theconductive electrodes 2142 by the way of high temperature brazing with silver-copper solder, or pure silver solder, or nickel solder under a protective atmosphere of 600 to 1100 °C.The leading wire 22 is connected to theconductive electrode 2142 by the way of tin welding with a high-temperature welding paste, and a use temperature is greater than 300 °C. - Since the sheet-shaped
substrate 212 made of a metallic material has a good conductivity, in order to prevent energy loss, throughholes 2122 are provided in a section of a length direction of the sheet-shapedsubstrate 212 where theconductive electrode 2142 is located. The throughholes 2122 can isolate heat, and reduce heat delivered to the second end B. - Since the section corresponding to the
conductive electrode 2142 has a relatively low temperature, tobaccos cannot be sufficiently atomized, and tobacco shreds can store and absorb a certain amount of tobacco tar, so the tobacco tar can be prevented or reduced from leakage. - A great temperature gradient exists between the section of the
heating element 21 corresponding to theheating resistor 2141 for inserting into tobaccos and that corresponding to theconductive electrodes 2142, and the section corresponding to theconductive electrode 2142 has a relatively low temperature and small heat dissipation, which facilitates effective use of energy. - In order to isolate the
heating resistor 2141 from outside air, and further extend service life and stability thereof, theheating element 21 further comprises anisolation layer 216 covered outside theconductive path 214. - The
isolation layer 216 is a glaze layer formed by sintering a glass glaze, and a thickness is usually less than 0.1 mm thereof. Two sides of the sheet-shapedsubstrate 212 are covered by theisolation layer 216 respectively. The glaze layer allows a surface of theheating element 21 to be smooth, and has a small roughness to reduce adhesion of smoke stains and smoke tar after baking of tobaccos, and facilitate scrubbing. In other embodiments, theisolation layer 216 also can be covered only on one side where theconductive path 214 is located. - Preferably, as shown in
FIG. 6 , in order to facilitate inserting theheating element 21 into the cigarette 3, a width of theheating element 21 from the first end A to the second end B gradually increases, so theheating element 21 is in a sword shape; the first end A is narrow, combining with a thinning structure of theblade portion 211, so that a resistant force is relatively small when theheating element 21 is inserted, to facilitate insertion, and accumulation of tobaccos on sides of theheating element 21 also can be effectively reduced. A bottom of the heating element becomes wider to facilitate increasing strength of theheating element 21, and prevent fracture of the heating element due to inserting and pulling the cigarette several times. - Generally, an angle between the two opposite sides in a width direction of the
sharp head 215 is greater than an angle between the two opposite sides in a width direction of the second end B of theheating element 21. In other embodiments, theheating element 21 also can be a triangle. - Referring to
FIG. 2 again, the mountingbase 23 is sleeved on the second end B of theheating element 21, i.e., sleeved on the end led out of the leadingwires 22 of theheating element 21, and sleeved onto the electrical connection portion. In other embodiments, the mountingbase 23 also can be an individual component, which is separately mounted on theheating element 21. - The
sharp head 215 is located on one end of theheating element 21 away from the mountingbase 23, and the mountingbase 23 and thesharp head 215 are respectively located on two opposite ends of theheating element 21. After one end of thesharp head 215 of theheating element 21 is inserted into the sleeve 1, the mountingbase 23 abuts against an outer end of the sleeve 1, to define an insertion depth of theheating element 21. - Since through
holes 2122 are provided in the section of a length direction of the sheet-shapedsubstrate 212 where theconductive electrode 2142 is located, transmission of heat to the second end B is reduced, and excess temperature of the mountingbase 23 also can be prevented. - Since a heating zone is not disposed between an end portion of the second end B where the mounting
base 23 is located and theconductive electrodes 2142, possibility of producing noxious gas is reduced, and a range of selecting materials of the mountingbase 23 is extensive to reduce cost. Generally, the mounting base is formed by injection molding using high-molecular polymer, and the commonly used material is polyether-etherketone, high-temperature nylon and the like. - It shall be understood that the above respective technical features can be combined optionally for use.
- 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 as defined by the appended claims.
