Description

Technical Field

[0001] The invention relates to the field of tobacco flue-curing machines, and in particular to an intelligent air-heating tobacco flue-curing machine. Background Art

[0002] The smoke released by tobacco during combustion and cracking contains more than 3,800 known chemical substances, most of which are harmful to the human body, including carbon monoxide, nicotine, amines, phenols, heavy metal elements, etc., and the smoke produced by combustion will cause secondhand smoke harm to the surrounding environment, causing others to smoke passively, making the call for tobacco control increasingly louder. Although electronic cigarettes have developed rapidly in recent years, they are nothing more than using heating wires to heat and atomize liquid tobacco oil or semi-solid tobacco paste. Electronic cigarettes appeared as a smoking cessation product when they were first born, and they are not real tobacco products, and cannot satisfy smokers' pursuit of tobacco flavor.

[0003] Studies have shown that the content of harmful substances in the smoke produced by heating tobacco without burning it is 80% lower than that of traditional cigarettes. Therefore, the treatment method of heating tobacco products without burning them is highly valued by my country's national tobacco industry authorities and major tobacco companies in the world. Based on this feature, researchers have developed a heat-not-burn tobacco curing machine, which controls the heating temperature of the heating wire to prevent the cigarette from being completely burned.

[0004] The heat-not-burn tobacco-curing machine is generally provided with a passage for inserting cigarettes on the machine body, and a dust cover is provided at the insertion opening of the passage. The dust cover is connected to the machine body in a sliding manner, and the cigarette can be inserted by sliding the dust cover open. The existing tobacco-curing machine structure has the following problems:

[0005] First, the air inlet is generally arranged at the lower middle part or at the lower part of the cigarette holder; this arrangement will inevitably cool the heating wire at the bottom, resulting in poor effect in baking the cigarettes.

[0006] Second, after inserting the cigarette, you still need to press the corresponding control button to make the heating device heat and bake the cigarette; it can be seen that the use is not smart and convenient enough;

[0007] Third, the layout of the thermal insulation structure is not reasonable enough, and the thermal insulation effect still needs to be further improved;

[0008] Fourth, the volatilized smoke and smoke oil can easily flow downward, causing cleaning dead corners and corroding electronic components. Summary of the invention

[0068] Please refer to Figures 1 to 7 As shown, it shows the specific structure of the first preferred embodiment of the present invention, which is an intelligent air-heating tobacco curing machine, including a casing 10 and a tobacco cup 20 arranged in the casing 10, a heating plate 30, a surrounding insulation layer 41, a touch switch 50, a detection switch 60, a main control board 70 and a temperature detection element 80.

[0069] The housing 10 includes an upper housing 11 and a lower housing 12, wherein the upper housing 11 includes an upper housing cover 111, a first upper housing seat 112 assembled on the upper housing cover 111, a second upper housing seat 113 arranged on the upper housing cover 111, and a fixing member 114 supported on the second upper housing seat 113; the touch switch 50 and the detection switch 60 are arranged on the first upper housing seat 112, and the cigarette holder 20 is installed on the fixing member 114; the lower housing 12 has an installation cavity 121 with an opening facing upward; a rechargeable battery 1211 is arranged in the installation cavity 121, and the main control board 70 is installed in the installation cavity 121; the upper housing 11 is detachably installed on the top of the installation cavity 121 through the upper housing cover 111, and the second upper housing seat 113 is arranged on the bottom of the upper housing cover 111.

[0070] In the embodiment of the present application, the cigarette holding cup 20 has a cavity 21 with an upper opening, and at least one air inlet window 22 is provided between the upper opening and the casing 10; the bottom of the cigarette holding cup 20 is provided with a heat conducting portion 23 for contacting the cigarette, and the heating plate 30 is provided at the bottom of the heat conducting portion 23; the peripheral heat insulation layer 41 is covered on the peripheral side of the cigarette holding cup 20; a first air duct 1 is formed on the outer side of the peripheral heat insulation layer 41, and the first air duct 1 is connected to the outside and the air inlet window 22. The outside gas enters the cavity 21 through the first air duct 1 and the air inlet window 22, and a second air duct 2 for air intake from top to bottom is formed in the cavity 21. A cavity 21 with an upper opening is provided in the smoke cup 20, and an air intake window 22 is provided between the upper opening and the casing 10; since the entire smoke cup 20 has a certain temperature when the smoke curing machine is in use; the air is flowed from top to bottom, so that the temperature of the air can be preheated when flowing downward from the top of the smoke cup 20, and the heating plate 30 will not be cooled when reaching the bottom, and the preheated air can be used to participate in the baking of cigarettes, which can improve the problem of poor baking effect of cigarettes in the past.

[0071] Specifically, the heat-conducting part 23 is a heat-conducting protrusion 231 protruding from the bottom of the cigarette cup 20 into the cavity 21, and a recess 232 is formed, and the heating plate 30 is arranged in the recess 232; the heat generated by the heating plate 30 is transferred to the heat-conducting protrusion 231, and the cigarette inserted into the cigarette cup 20 can be cured by the heat of the heat-conducting protrusion 231. A heat-conducting needle 233 for inserting upward into the cigarette extends above the heat-conducting part 23. The heat-conducting needle 233 is inserted into the cigarette to accelerate the heat transfer speed and shorten the preheating time in the early stage. Moreover, after the cigarette is inserted into the cavity 21, a certain space is formed between the raised heat-conducting protrusion 231 and the cigarette; it is not only convenient for air to enter the cigarette, but also the space can be used to contain tobacco stains, which is convenient for one-time cleaning after long-term use. In addition, the heating plate 30 transfers heat to the heat-conducting protrusion 231, and the heat-conducting protrusion 231 is in contact with the cigarette; the heating plate 30 does not directly contact the cigarette, which can effectively avoid the situation of open flames during the tobacco curing process. More specifically, the wall surface of the cavity 21 of the above-mentioned cigarette holding cup 20 heats the cigarette mainly by radiation and convection, and the heat-conducting protrusion 231 is supplemented by heat conduction; the heat-conducting needle 233 is inserted into the cigarette, and the heat-conducting needle 233 heats the cigarette mainly by heat conduction, so that the effect of heating the inside and outside of the cigarette can be formed, so that the effect of curing the cigarette is better. Of course, the specific structure of the heat-conducting protrusion 231 is not limited to the heat-conducting needle 233 structure, and the heat-conducting protrusion 231 can also be directly set to conduct heat, as long as it can conduct heat to the cigarette.

[0072] A bottom heat-insulating layer 42 is provided at the bottom of the heating plate 30. By providing the bottom heat-insulating layer 42 and the above-mentioned peripheral heat-insulating layer 41, the peripheral heat-insulating layer 41 is directly provided on the outer side of the smoke containing cup 20, thereby optimizing the setting mode of the heat-insulating structure; on the one hand, the overall structure of the smoke-curing machine can be made simpler and more compact, and on the other hand, the heat-insulating effect can be improved; and, in combination with the bottom heat-insulating layer 42 provided at the bottom of the heating plate 30, all-round heat-insulation is formed, the heat utilization rate is improved, and energy saving is more enhanced. At the same time, the heat damage from the bottom of the heating plate 30 to the lower part and the electronic parts such as the battery is reduced, which is beneficial to ensuring the performance of the smoke-curing machine and extending its service life.

[0073] The heating plate 30, the touch switch 50, the detection switch 60 and the temperature detection element 80 are connected to the main control board 70 respectively. In the embodiment of the present application, the housing 10 has a rotating member that can selectively open the upper opening of the cavity 21 for cigarette insertion or block it; when the rotating member rotates to open the upper opening of the cavity 21, the rotating member triggers the touch switch 50 to start the tobacco drying machine for detection. When a cigarette is inserted, the cigarette triggers the detection switch 60 to feed back a signal to the main control board 70, and the main control board 70 controls the heating plate 30 to heat. The temperature detection element 80 is arranged on the wall surface of the cavity 21 of the cigarette cup 20, and the information fed back by the temperature detection element 80 is sent to the main control board 70 to control the temperature of the heating plate 30. Specifically, the rotating part is a toggle switch 13, which has a spherical portion 131 and a first through hole 132 passing through the spherical portion 131; the housing 10 is also provided with a first avoidance hole 14 connected to the cavity 21; the spherical portion 131 covers the upper end of the first avoidance hole 14, and toggling the spherical portion 131 can selectively connect the first through hole 132 to the first avoidance hole 14.

[0075] In addition, a first sealing pad 1144 is provided on the top of the fixing member 114, and a second sealing pad 1121 is provided on the bottom of the first upper housing seat 112; the second sealing pad 1121 is against the first sealing pad 1144; the first sealing pad 1144 and the second sealing pad 1121 are provided, so that the cigarette holder 20 and the housing 10 can be better sealed after being assembled; smoke can be prevented from volatilizing, and heat can be prevented from being dissipated to cause the housing to heat up, saving energy. The air intake window structure is improved, and the upper end opening of the cigarette holder and the fixing member are assembled to form an air intake window, which can prevent smoke oil from flowing down to cause cleaning dead corners and corrode electronic components. Furthermore, an annular protrusion 1122 is provided on the inner side surface of the second sealing pad 1121, and the annular protrusion 1122 can form an interference fit with the cigarette inserted into the cigarette cup 20; specifically, when the cigarette is inserted, the annular protrusion 1122 undergoes elastic deformation, so that the cigarette inserted into the cigarette cup 20 fits tightly therewith, so as to further improve the effect of preventing smoke from escaping and heat waste.

[0076] In the embodiment of the present application, the toggle switch 13 is rotatably disposed on the first upper housing seat 112, and touch windows 1311 are provided on both sides of the ball portion 131 of the toggle switch 13; the touch switch 50 is disposed on the side of the ball portion 131, and the contact of the touch switch 50 is retractably disposed in the touch window 1311; the touch switch 50 can be triggered to open or close by toggling the ball portion 131, and the structural setting is reasonable and ingenious.

[0077] In the embodiment of the present application, the detection switch 60 is an infrared detection switch 61, which is arranged on the side of the toggle switch 13. After the cigarette is inserted into the first through hole 132, the infrared detection switch 61 is triggered; then the signal is fed back to the main control board 70, and the main control board 70 controls the heating plate 30 to heat up.

[0083] Please refer to Figures 8 to 11 As shown, it shows the specific structure of the second preferred embodiment of the present invention. The specific structure of the second preferred embodiment is basically the same as the specific structure of the first preferred embodiment, except that the detection switch 60 is a spring touch switch 62.

[0084] In the embodiment of the present application, the detection switch 60 is a spring touch switch 62, and the spring touch switch 62 includes a spring 621 and a detection conduction point 622. A portion of the spring 621 extends into the first through hole 132. After the cigarette is inserted into the first through hole 132, the spring 621 is squeezed by the cigarette and deformed toward the detection conduction point 622 and connected to the detection conduction point 622. Of course, the detection switch 60 can be a detection switch 60 other than the infrared detection switch 61 and the spring touch switch 62, and is not limited to the detection switch 60 described in this embodiment.

[0085] Its general working principle is as follows:
