Description

[0001] This divisional application is a divisional application based on the Chinese patent application with application number 201910171474.5, application date March 7, 2019, and invention name “Low-temperature baking smoking utensils”. Technical Field

[0002] The present invention relates to the field of smoking articles, and in particular to a low-temperature baking smoking article. Background Art

[0003] Low-temperature baking smoking utensils generally include a heating body and a power supply unit. The power supply unit provides electrical energy to the heating body. When the heating body is powered on, it generates heat to bake the smoking material contained in the low-temperature baking smoking utensils, thereby generating smoke that the user can directly inhale. Low-temperature baking smoking utensils are favored by many smokers because they are portable, do not produce open flames, and are environmentally friendly.

[0004] Existing low-temperature baking smoking utensils generally adopt central heating and peripheral heating. In the central heating method, the heating body is inserted into the smoking material, and in the peripheral heating method, the cylindrical heating body wraps the smoking material, and the heating body is in direct contact with the smoking material, so that the heat generated by the heating body is transferred to the heating material, thereby baking the smoking material.

[0005] Both the central heating and peripheral heating methods are heat conduction heating methods in which the heating body is in direct contact with the smoke-generating material. For the central heating method, there will be a problem of too high central temperature and incomplete peripheral heating; for the peripheral heating method, there will be a problem of too high peripheral temperature of the smoke-generating material and incomplete central heating, that is, both the central heating method and the peripheral heating method have the problem of uneven heating.

[0044] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in this specification and in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0045] Implementation Method 1

[0046] like Figure 1 As shown, a low-temperature baking smoking device provided in the first embodiment of the present invention is shown. The low-temperature baking smoking device mainly comprises a shell 1, a bracket 2, a heating component 3, a heat insulating component 4, a power supply unit 5, a control component 6 and a temperature measuring component 7.

[0047] The housing 1 comprises a flat annular main body 11 with upper and lower openings, and an upper cover 12 and a lower cover 13 located at upper and lower sides of the main body 11 respectively.

[0048] The bracket 2 is received and fixed in the main body 11 . The bracket 2 cooperates with the main body 11 and the upper cover 12 and the lower cover 13 , so as to divide the main body 11 into a plurality of chambers.

[0049] like Figure 1 and Figure 2 As shown, the heating assembly 3 includes a fixing seat 30 , a heating substrate 31 , a far-infrared coating 32 , a first conductive module 331 , and a second conductive module 332 .

[0050] The fixing base 30 is disposed on the lower cover 13, and the fixing base 30 is located between the upper cover 12 and the lower cover 13. The fixing base 30 is provided with an air inlet hole penetrating the center of the fixing base 30. The heating substrate 31 is a longitudinal hollow tubular structure, and the heating substrate has a first end a and a second end b opposite to each other, that is, the heating substrate has an upper end and a lower end opposite to each other. The heating substrate 31 is located on the fixing base 30, and the heating substrate 31 is made of a high temperature resistant and transparent material such as quartz glass, ceramics or mica.

[0051] The far-infrared coating 32 is coated on the outside of the heating substrate 31. The far-infrared coating 32 is made by mixing far-infrared electrothermal ink, ceramic powder and inorganic adhesive, and then printing it on the surface of the heating substrate 31, and then drying and curing it for 60 minutes. The thickness of the far-infrared coating 32 is 30um-50um.

[0052] In this embodiment, the first conductive module 331 and the second conductive module 332 are conductive coatings respectively coated on the upper and lower sides of the heating substrate 31, and the conductive coatings are made of silver powder coatings. The conductive coatings are in contact with the far-infrared coating 32, and the far-infrared coating 32 is located between the two conductive coatings.

[0053] It is understandable that the first conductive module 331 and the second conductive module 332 may also be made of a metal material with high conductivity.

[0054] like Figure 1 and Figure 3 As shown, the heat insulating member 4 is sleeved outside the heating substrate 31, and the heat insulating member includes a heat insulating inner tube 41, a heat insulating outer tube 42, two annular sealing plugs 43 and an aerogel (not shown) arranged between the heat insulating inner tube 41 and the heat insulating outer tube 42. The heat insulating inner tube 41 and the heat insulating outer tube 42 are coaxially arranged, and the two sealing plugs 43 are respectively located at the upper and lower ends of the heat insulating inner tube 41 and the heat insulating outer tube 42, and are used to seal the receiving space formed between the heat insulating inner tube 41 and the heat insulating outer tube 42. The aerogel can be silicon-based, carbon-based, sulfur-based, metal oxide-based, and metal-based. Since more than 80% of the aerogel is air, it has a very good heat insulating effect. The inner side of the heat insulating inner tube 41 is coated with an infrared light reflecting material, so that the far-infrared light emitted by the far-infrared coating 32 after being energized is reflected back to the inside of the heating substrate 31 to heat the smoke-generating material located inside the heating substrate 31, providing an effective utilization rate of the far-infrared light emitted by the far-infrared coating 32 and improving the heating efficiency.

[0055] The power supply unit 5 is mainly used to provide electric energy to the heating component 3 and the control component 6. The power supply unit 5 is accommodated in the main body 11. In this embodiment, the power supply unit 5 is a rechargeable battery.

[0056] like Figure 1 and Figure 4 As shown, the control component 6 mainly includes a circuit board 61, a controller 62 and a switch button 63. The circuit board 61 is arranged on the bracket 2, the controller 62 is fixed on the circuit board 61, and the switch button 63 is protruded on the main body 11. By pressing the switch button 63, the far-infrared coating 32 can be powered on or off, that is, the heating component 3 can be heated or not heated.

[0057] The temperature measuring element 7 is arranged inside the heating substrate 31. The temperature measuring element 7 is a temperature sensor for detecting the real-time temperature of the heating substrate 31 and transmitting the detected real-time temperature to the controller 62. The controller 62 adjusts the current flowing through the far-infrared coating 32 according to the real-time temperature. Specifically, when the temperature measuring component 7 detects that the real-time temperature inside the heating substrate 31 is low, for example, when the temperature measuring component 7 detects that the temperature inside the heating substrate 31 is less than 150°C, the controller 62 controls the power supply unit 5 to output a higher voltage to the conductive coating, thereby increasing the current fed into the far-infrared coating 32, increasing the heating power of the smoking substance, and reducing the waiting time for the user to take the first puff of cigarette; when the temperature measuring component 7 detects that the temperature of the heating substrate 31 is 150°C-200°C, the controller 62 controls the power supply unit 5 to output a normal voltage to the conductive coating; when the temperature measuring component 7 detects that the temperature of the heating substrate 31 is 200°C-250°C, the controller 62 controls the power supply unit 5 to output a lower voltage to the conductive coating; when the temperature measuring component 7 detects that the temperature inside the heating substrate 31 is 250°C or above, the controller 62 controls the power supply unit 5 to stop outputting voltage to the conductive coating.

[0058] In this embodiment, a far-infrared coating 32 is coated on the outside of the heating substrate 31. After being energized, the far-infrared coating 32 emits far-infrared light that penetrates the heating substrate 31 to radiate and heat the smoke-generating substance inside the heating substrate 31. Since far-infrared light has strong penetrability, it can penetrate the outer smoke-generating substance into the interior, so that the heating of the smoke-generating substance is more uniform.

[0059] Implementation Method 2

[0060] like Figure 5As shown, the heating component 3 of the low-temperature baking tobacco utensil provided in the second embodiment of the present invention, the first conductive module 341 and the second conductive module 342 of the heating component 3 are conductive rings sleeved on the heating base 31, and the conductive rings are clamped and fixed between the heating base 31 and the heat insulating member 4. By clamping and fixing between the heat insulating member 4 and the heating base 31, good contact between the conductive ring and the far-infrared coating 32 on the heating base 31 is achieved.

[0061] Implementation Method 3

[0062] like Figure 6 As shown, the heating component 3 of the low-temperature baking smoking device provided in the third embodiment of the present invention is mainly different from that in the first embodiment in that the heating component in the present embodiment further includes a third conductive module 333, and the third conductive module 333 is located between the first conductive module 331 and the second conductive module 332. The first conductive module 331, the second conductive module 332 and the third conductive module 333 divide the far-infrared coating 32 into two parts, and by energizing and de-energizing the three conductive coatings, the two far-infrared coatings 32 are energized at different times, that is, the segmented heating of the smoking substance contained in the heating substrate 31 is realized.

[0063] Implementation Method 4

[0064] like Figure 7 and Figure 8 , which is a schematic diagram of the heating assembly 3 of the low-temperature baking smoking device provided in the fourth embodiment of the present invention after the fixing seat 30 is removed. The main difference between the heating assembly 3 provided in the first embodiment and the heating assembly 3 provided in the first embodiment is that the first conductive module 351 and the second conductive module 352 are made of metal materials with high conductivity, for example, they can be made of gold and its alloys, silver and its alloys, or copper and its alloys. The first conductive module 351 includes a first circular portion 3511 and a first strip portion 3512. The first circular portion 3511 is sleeved on the first end a of the heating substrate 31. The first strip portion 3512 extends from the first circular portion 3511 along the longitudinal direction of the heating substrate 31 toward the second end b of the heating substrate 31, that is, the first strip portion 3512 extends downward from the first circular portion 3511 along the axial direction of the heating substrate 31.

[0065] The second conductive module 352 includes a second circular portion 3521 and a second long strip portion 3522. The second circular portion 3521 is sleeved on the second end b of the heating substrate 31, and the second long strip portion 3522 extends from the second circular portion 3521 along the longitudinal direction of the heating substrate 31 toward the first end a of the heating substrate 31, that is, the second long strip portion 3522 extends upward from the second circular portion 3521 along the axial direction of the heating substrate 31.

[0066] In the longitudinal direction of the heating substrate 31, the length of the first strip portion 3512 is less than the distance between the first annular portion 3511 and the second annular portion 3521, that is, the first strip portion 3512 does not contact the second annular portion 3521. In the longitudinal direction of the heating substrate 31, the length of the second strip portion 3522 is less than the distance between the second annular portion 3521 and the first annular portion 3511, that is, the second strip portion 3522 does not contact the first annular portion 3511.

[0067] In the longitudinal direction of the heating substrate 31, the area 311 between the first strip portion 3512 and the second annular portion 3521 is not coated with the far-infrared coating 32, and the area 312 between the second strip portion 3522 and the first annular portion 3511 is not coated with the far-infrared coating 32. The areas 311 and 312 are annular areas, that is, the areas 311 and 314 are not coated with the far-infrared coating on the entire circumference of the heating substrate 31. The far-infrared coating 32 is applied to the overlapping portion of the first strip portion 3512 and the second strip portion 3522 in the axial direction of the heating substrate 31.

[0068] The first long strip portion 3512 and the second long strip portion 3522 are respectively located on opposite sides of the heating substrate 31. When the first annular portion 3511 and the second annular portion 3521 are electrically connected to the power supply unit 5, the current on the first long strip portion 3512 flows through the far-infrared coating 32 along the circumferential direction of the heating substrate 31 and reaches the second long strip portion 3522.

[0069] Compared with the existing current flowing along the axial direction of the heating substrate 31 from the first end a to the second end b of the heating substrate 31, the current in this embodiment flows along the circumferential direction of the heating substrate 31, shortening the flow distance of the current in the far-infrared coating 32 and reducing the resistance of the far-infrared coating 32 in the current path. Under the same resistance conditions, the far-infrared coating 32 in this embodiment is thinner, which can save costs and improve the market competitiveness of the low-temperature baking smoking utensils provided by this embodiment.

[0070] Implementation Method 5

[0071] like Fig. 9 and Fig.10 , which is a schematic diagram of the heating component 3 provided in the fifth embodiment of the present invention after removing the fixing base 30 , and the main difference between the heating component 3 and the first embodiment is that the heating component 3 further includes a third conductive module 363 and a fourth conductive module 364 .

[0072] The first conductive module 361 includes a first circular portion 3611 and a first long strip portion 3612. The first circular portion 3611 is sleeved on the first end a on the outside of the heating substrate 31, and the first long strip portion 3612 extends from the first circular portion 3611 along the longitudinal direction of the heating substrate 31 toward the second end b of the heating substrate 31, that is, the first long strip portion 3612 extends downward from the first circular portion 3611 along the axial direction of the heating substrate 31.

[0073] The second conductive module 362 includes a second annular portion 3621 and a second strip portion 3622. The second annular portion 3621 is sleeved on the outer side of the middle end of the heating substrate 31. The second strip portion 3622 extends from the second annular portion 3621 along the longitudinal direction of the heating substrate 31 toward the first end a of the heating substrate 31, that is, the second strip portion 3622 extends upward from the second annular portion 3621 along the axial direction of the heating substrate 31. In the longitudinal direction of the heating substrate 31, the second strip portion 3622 and the first strip portion 3612 mostly overlap. In the circumferential direction of the heating substrate 31, the first strip portion 3612 and the second strip portion 3622 are symmetrically distributed on the outer side of the heating substrate 31.

[0074] In the longitudinal direction of the heating substrate 31, the length of the first strip portion 3612 is less than the distance between the first annular portion 3611 and the second annular portion 3621, that is, the first strip portion 3612 does not contact the second annular portion 3621. In the longitudinal direction of the heating substrate 31, the length of the second strip portion 3622 is less than the distance between the second annular portion 3621 and the first annular portion 3611, that is, the second strip portion 3622 does not contact the first annular portion 3611.

[0075] In the longitudinal direction of the heating substrate 31, the area 313 between the first strip portion 3612 and the second annular portion 3621 is not coated with the far-infrared coating 32, and the area 314 between the second strip portion 3622 and the first annular portion 3611 is not coated with the far-infrared coating 32. The areas 313 and 314 are annular areas, that is, the areas 311 and 314 are not coated with the far-infrared coating on the entire circumference of the heating substrate 31. The far-infrared coating 32 is applied to the overlapping portion of the first strip portion 3612 and the second strip portion 3622 in the axial direction of the heating substrate 31.

[0076] The third conductive module 363 includes a third circular portion 3631 and a third long strip portion 3632. The third circular portion 3631 surrounds the outer side of the second end b of the heating substrate 31, and the third long strip portion 3632 extends from the third circular portion 3631 along the first end a in the longitudinal direction of the heating substrate 31, that is, the third long strip portion 3632 extends upward from the second circular portion 3621 along the axial direction of the heating substrate 31, and the third long strip portion 3632 and the first long strip portion 3612 do not overlap.

[0077] The fourth conductive module 364 includes a fourth circular portion 3641 and a fourth long strip portion 3642. The fourth circular portion 3641 surrounds the outer side of the middle end of the heating substrate 31, and the fourth long strip portion 3642 extends from the fourth circular portion 3641 along the second end b in the longitudinal direction of the heating substrate 31, that is, the fourth long strip portion 3642 extends downward from the fourth circular portion 3641 along the axial direction of the heating substrate 31, and the fourth long strip portion 3642 and the second long strip portion 3622 do not overlap.

[0078] The fourth annular portion 3641 and the second annular portion 3621 are arranged to overlap, that is, the fourth strip portion 3642 and the second strip portion 3622 share the same fourth annular portion 3641, that is, the second strip portion 3622 and the fourth strip portion 3642 extend from the fourth annular portion 3641 (the second annular portion 3621) toward the first end a and the second end b of the heating base 31, respectively. In the longitudinal direction of the heating base 31, the fourth strip portion 3642 and the third strip portion 3632 mostly overlap. In the circumferential direction of the heating base 31, the third strip portion 3632 and the fourth strip portion 3642 are symmetrically distributed on the outer side of the heating base 31.

[0079] In the longitudinal direction of the heating substrate 31, the length of the third strip portion 3632 is smaller than the distance between the third circular portion 3631 and the fourth circular portion 3641, and the area 315 between the third strip portion 3632 and the fourth circular portion 3641 is not coated with the far-infrared coating 32; the length of the fourth strip portion 3642 is smaller than the distance between the fourth circular portion 3641 and the third circular portion 3631, and the area 315 between the fourth strip portion 3642 and the third circular portion 3631 is not coated with the far-infrared coating 32, and the area 315 and the area 316 are annular areas, that is, the far-infrared coating is not coated on the entire circumference of the heating substrate 31.

[0080] The first annular portion 3611 and the third annular portion 3631 are electrically connected to the positive pole of the power supply unit 5 , respectively, and the second annular portion 3621 or the fourth annular portion 3641 is electrically connected to the negative pole of the power supply unit 5 .

[0081] It is understandable that in some other embodiments, the second annular portion 3621 and the fourth annular portion 3641 may not overlap, that is, the second annular portion 3621 and the fourth annular portion 3641 surround the outer side of the heating substrate 31 separately and at intervals.

[0082] After the user touches or presses the switch button 63 of the low-temperature baking tobacco utensil, the low-temperature baking tobacco utensil starts to work. First, the controller 62 controls the third annular portion 3631 and the positive pole of the power supply unit 5 to be electrically conductive, and the fourth annular portion 3641 and the negative pole of the power supply unit 5 to be electrically conductive. A potential difference is formed between the third long strip portion 3632 and the fourth long strip portion 3642. The current flows from the third long strip portion 3632 along the circumferential direction of the heating substrate 31 through the far-infrared coating 32 between the two and reaches the fourth long strip portion 3642. The far-infrared coating 32 between the third circular portion 3631 and the fourth circular portion 3641 generates far-infrared rays, thereby radiating and heating the smoking substances in the cigarette between the third circular portion 3631 and the fourth circular portion 3641. When the temperature measuring component 7 detects that the temperature on the heating substrate 31 reaches the preset temperature, it indicates that the smoking substances in the cigarette between the third circular portion 3631 and the fourth circular portion 3641 have been completely baked, and the controller 62 controls the third circular portion 3631 and the fourth circular portion 3641 to disconnect from the power supply unit 5.

[0083] At the same time, the controller 62 controls the electrical conduction between the first annular portion 3611 and the positive pole of the power supply unit 5, and the electrical conduction between the second annular portion 3621 and the negative pole of the power supply unit 5, so that a potential difference is formed between the first long strip portion 3612 and the second long strip portion 3622. The current flows from the first long strip portion 3612 along the circumferential direction of the heating substrate 31 through the far-infrared coating 32 between the two and reaches the second long strip portion 3622. The far-infrared coating 32 between the first annular portion 3611 and the second annular portion 3621 generates far-infrared rays, thereby radiating and heating the smoking substance of the cigarette between the first annular portion 3611 and the second annular portion 3621. When the temperature measuring component 7 detects that the temperature on the heating substrate 31 reaches the preset temperature, it indicates that the smoking substance of the cigarette between the first annular portion 3611 and the second annular portion 3621 has been completely baked. The controller 62 controls the third annular portion 3631 and the fourth annular portion 3641 to disconnect from the power supply unit 5, and the cigarette is completely baked.

[0084] In this embodiment, the controller 62 controls the third annular portion 3631 and the fourth annular portion 3641 to be electrically connected to the positive and negative poles of the power supply unit 5, and the first annular portion 3611 and the second annular portion 3621 to be electrically connected to the positive and negative poles of the power supply unit 5, respectively, in different time periods, thereby achieving segmented heating of the smoking part of the cigarette, shortening the time from the initial operation of the low-temperature baking smoking utensil to the generation of the first puff of smoke, improving user experience, and increasing the smoke output rate of the cigarette.

[0085] It is understandable that the first annular portion 3611, the second annular portion 3621, the third annular portion 3631 and the fourth annular portion 3641 are mainly used as contacts for electrical conduction with the positive or negative pole of the power supply unit 5, and their shapes are not necessarily circular, and they can be set to any shape depending on the situation. The circular shape is conducive to the uniform distribution of the contact current and reduces the contact resistance of the current introduced into the first strip portion 3612 / the second strip portion 3622 / the third strip portion 3632 / the fourth strip portion 3642. It is understandable that in some other embodiments, the smoking part of the cigarette can also be divided into three sections, four sections, five sections or other sections for heating.

[0086] Implementation Method 6

[0087] like Fig.11 , which is a top view of the heating component 3 provided in the sixth embodiment of the present invention with the fixing base 30 removed. The main difference between the heating component 3 and the fourth embodiment is that the heating component 3 further includes a third conductive module 373 and a fourth conductive module 374 .

[0088] The first conductive module 371 includes a first long strip portion 3712 extending along the longitudinal direction of the heating substrate 31, the second conductive module 372 includes a second long strip portion 3722 extending along the longitudinal direction of the heating substrate 31, the third conductive module 373 includes a third long strip portion 3732 extending along the longitudinal direction of the heating substrate 31, and the fourth conductive module 374 includes a fourth long strip portion 3742 extending along the longitudinal direction of the heating substrate 31.

[0089] In the circumferential direction of the heating substrate 31, the first long strip portion 3712, the second long strip portion 3722, the third long strip portion 3732 and the fourth long strip portion 3742 are arranged in sequence on the outer side of the heating substrate 31 in a clockwise and equidistant manner. The current on the first long strip portion 3712 flows through the far-infrared coating 32 clockwise along the circumferential direction of the heating substrate 31 and reaches the second long strip portion 3722, and the current on the first long strip portion 3712 flows through the far-infrared coating 32 counterclockwise along the circumferential direction of the heating substrate 31 and reaches the fourth long strip portion 3742. The current on the third long strip portion 3732 flows through the far-infrared coating 32 clockwise along the circumferential direction of the heating substrate 31 and reaches the fourth long strip portion 3742, and the current on the third long strip portion 3732 flows through the far-infrared coating 32 counterclockwise along the circumferential direction of the heating substrate 31 and reaches the second long strip portion 3722.

[0090] It can be understood that the first strip portion 3712 and the third strip portion 3732 are electrically connected to the positive pole of the power supply unit 5 , and the second strip portion 3722 and the fourth strip portion 3742 are electrically connected to the negative pole of the power supply unit 5 .

[0091] Compared with embodiment 4, in the circumferential direction of the heating substrate 31, the first long strip portion 3712, the second long strip portion 3722, the third long strip portion 3732 and the fourth long strip portion 3742 in this embodiment divide the far-infrared coating 32 coated on the outside of the heating substrate 31 into four parts, further shortening the flow distance of the current on the far-infrared coating 32, and further reducing the resistance of the far-infrared coating 32 in the current path. Under the same resistance conditions, the thickness of the far-infrared coating 32 in this embodiment can be made thinner, which can further save costs and improve the market competitiveness of the low-temperature baking tobacco utensils provided by this embodiment.

[0092] It is understandable that in some other embodiments, the far-infrared coating 32 may be divided into six, eight, or ten parts along the circumferential direction of the heating substrate 31 to conduct current, further shortening the flow distance of the current on the far-infrared coating 32 .

[0093] It should be noted that the preferred embodiments of the present invention are given in the specification and drawings of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. These embodiments are not used as additional limitations on the content of the present invention.

In addition, the above-mentioned technical features continue to be combined with each other to form various embodiments not listed above, which are all regarded as the scope of the present invention; further, for ordinary technicians in this field, they can be improved or transformed according to the above description, and all these improvements and transformations should belong to the protection scope of the claims attached to the present invention.
