DETAILED DESCRIPTION

The present invention is further described in detail below in conjunction with the accompanying drawings.

This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make non-creative modifications to this embodiment as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.

The present embodiment relates to a high-efficiency tobacco curing device, as shown in FIGS. 1-8 , comprising: a housing 1 , a heating component 2 , and a power supply component 3 .

As shown in FIG1 , the tobacco curing machine is configured as a strip to facilitate users to hold or carry the tobacco curing machine. An insertion port 11 is provided at one end of the housing 1. When in use, the lit end of the cigarette is inserted into the tobacco curing machine from the insertion port 11 for baking and heating, while the mouthpiece of the cigarette is left outside the housing 1 for the convenience of users to smoke. An external air inlet 12 is provided on the surface of the housing 1, and the external air inlet 12 is connected to the heating component 2 inside the tobacco curing machine to provide air for users to smoke substances produced by baking cigarettes in the tobacco curing machine.

In the embodiment, as shown in FIGS. 4 and 8 , the housing 1 includes: an upper housing 13, a lower housing 14, and a bracket 15. The upper housing 13 and the lower housing 14 are arranged at the outermost side to protect the tobacco curing device, and the bracket 15 is arranged on the inner side of the upper housing 13 and the lower housing 14 to install internal parts such as the heating component 2 and the power supply component 3. The upper housing 13 and the lower housing 14 are connected by a threaded structure, so that the upper housing 13 and the lower housing 14 can be disassembled to facilitate the parts on the inner bracket 15 to be repaired, cleaned, etc. Of course, in other embodiments, the housing 1 can also be arranged to be integrally formed.

The heating assembly 2 is arranged on one end of the housing 1 near the insertion port 11, as shown in FIG6, and comprises: an inner tube, a heating element 25, and the heating element 25 comprises: a first heating portion 21 arranged on the circumference of the inner tube and a second heating portion 22 arranged on the bottom of the inner tube. A receiving space 231 is arranged in the middle of the inner tube, and the receiving space 231 corresponds to the insertion port 11. The cigarette is inserted into the receiving space 231 through the insertion port 11. An inner air inlet 232 is provided at the bottom of the accommodating space 231, and the inner air inlet 232 is connected with the outer air inlet 12 to form an air inlet passage, so that the outside air can enter from the outer air inlet 12 and enter from the inner air inlet 232 to the bottom of the accommodating space 231, forming an air inlet flow, providing air for the operation of the tobacco curing machine, so that the user can inhale the substances produced by curing the cigarettes.

The tobacco curing machine heats and bakes the cigarettes in the accommodating space 231 through the combined action of the first heating part 21 and the second heating part 22. The combined action of the heating element 5 makes the tobacco curing machine have high heating efficiency, short cold start time, reduced waiting time for use, and optimized user experience.

Among them, the second heating part 22 is arranged at the bottom of the accommodating space 231 to heat the bottom of the cigarette in the accommodating space 231; the first heating part 21 is arranged on the surrounding side of the accommodating space 231 to heat the surrounding side of the cigarette in the accommodating space 231. The first heating part 21 is arranged on the surrounding side of the accommodating space 231, and the action area is large, which can surround the whole cigarette and heat the cigarette in the accommodating space 231 as a whole. The positions of the first heating part 21 and the second heating part 22 are arranged to cooperate with each other to form a three-dimensional heating structure to realize the three-dimensional heating of the cigarette in the accommodating space 231 by the heating component 2. The three-dimensional heating structure makes the heating component 2 heat the cigarette more evenly, so that when the working temperature of the heating element 25 is 220-260 degrees, the inside of the cigarette can reach the temperature required for baking, and achieve a good baking effect. Compared with the general tobacco curing device heating work of more than 300 degrees, it is much lower, so the tobacco curing device of this scheme can reduce the energy consumption of the tobacco curing device, and at the same time avoid overheating of the part of the cigarette close to the heating element 25, and produce other harmful substances or substances that affect the taste of the cigarette.

In this embodiment, the first heating part 21 and the second heating part 22 of the heating element 25 are integrally formed spiral heating wires, and the integrated heating element 25 realizes a three-dimensional heating structure. The heating values of different regions are set by setting the density of the spiral heating wires in different regions, thereby optimizing the three-dimensional heating effect of the heating element 25. Of course, in other embodiments, the heating element 25 may also be other structures, such as a heating net or an etched heating plate integrally stamped into a barrel structure as shown in FIG9 .

In this embodiment, a low heat conduction layer 24 is further provided on the outer side of the second heating part 22 and the first heating part 21. The low heat conduction layer 24 covers the outer side of the second heating part 22 and the first heating part 21, which can effectively prevent the heat generated by the second heating part 22 and the first heating part 21 from being lost to the outside, thereby ensuring the heating efficiency of the tobacco curing device and also playing a certain role in heat preservation for the cigarettes in the accommodating space 231. As a preferred solution, the low heat conduction layer 24 is a porous ceramic material.

In this embodiment, the second heating part 22 and the first heating part 21 are arranged on the outside of the inner tube, located between the low heat conduction layer 24 and the inner tube, so that the second heating part 22 and the first heating part 21 will not come into direct contact with the cigarettes in the accommodating space 231, avoiding the generation of some harmful substances or causing the burning of the cigarettes. The inner tube is set as a high heat conduction inner tube 23, so that the heat generated by the second heating part 22 and the first heating part 21 will not be blocked by the high heat conduction inner tube 23, and can be efficiently conducted to the cigarettes in the accommodating space 231 to ensure the heating efficiency of the tobacco flue-curing device. As a preferred solution, the high heat conduction inner tube 23 is made of alumina material, and the spiral heating wire is integrally sintered and injection molded with the high heat conduction inner tube 23. Of course, in other embodiments, the high heat conduction inner tube 23 can also be made of other materials.

In this embodiment, as shown in Figures 3 and 4, an insulation tube is provided between the shell 1 and the heating component 2 to prevent the heat inside the insulation tube from being transferred to the outside of the insulation tube, causing the heat loss of the heating component 2, affecting the heating efficiency and thermal insulation effect of the tobacco flue-curing machine; at the same time, it can prevent the heat of the heating component 2 from being transferred to the shell 1 outside the insulation tube, causing the temperature of the outer shell 1 to rise, and affecting the user's experience of holding the tobacco flue-curing machine.

As a preferred solution, the heat-insulating tube is a double-layer heat-insulating tube 4, which is arranged on the inner side of the bracket 15. The middle layer of the double-layer heat-insulating tube 4 is an air channel 41, the upper end of the air channel 41 is connected to the outer air inlet 12 of the shell 1, and the lower end of the air channel 41 is connected to the inner air inlet 232 at the bottom of the accommodating space 231. The air entering the shell 1 from the outer air inlet 12 will pass through the air channel 41 and then enter the accommodating space 231 from the inner air inlet 232. The formed intake airflow will bring the heat in the double-layer heat-insulating tube 4 to the accommodating space 231. The air intake airflow passing through the air channel 41 of the double-layer insulation tube 4 will take away the heat dissipated outward from the inner side of the double-layer insulation tube 4, and prevent the heat from further dissipating to the shell 1 outside the double-layer insulation tube 4, causing the temperature of the shell 1 to rise and affecting the user experience. At the same time, the air intake airflow brings the heat of the double-layer insulation tube 4 back to the accommodating space 231, ensuring the thermal efficiency of the tobacco curing machine, and the airflow entering the accommodating space 231 through the air channel 41 of the double-layer insulation tube 4 will become warmer due to the absorption of a certain amount of heat, so that the user will not directly inhale the cold air from the outside and cause a bad user experience. Of course, in other embodiments, the insulation tube can also be set as a vacuum insulation tube or other insulation tube structures to prevent the heat inside the insulation tube from being transferred to the outside of the insulation tube.

As a preferred solution, the inner layer of the double-layer insulation tube 4 is a low thermal conductivity layer 24, and the inner side of the air channel 41 is the outer side of the low thermal conductivity layer 24, so that the air entering from the outer air inlet 12 will bring the heat outside the low thermal conductivity layer 24 into the accommodating space 231, and the intake air flow has a higher efficiency in absorbing heat, and the air entering the accommodating space 231 brings back more heat and has a better insulation effect on the outside. The low thermal conductivity of the low thermal conductivity layer 4 allows the intake air flow to absorb the heat dissipated outward while avoiding the intake air flow causing a large amount of heat loss in the heating element 22, which causes the heating element 22 to cool down and affect the heating efficiency of the tobacco curing machine.

In this embodiment, as shown in FIGS. 3, 5, and 6, an upper silicone 51 assembly 5 is provided at the upper end of the heating component 2 to prevent the heat in the heating component 2 from being lost from the upper end of the heating component 2, thereby improving the heat preservation effect of the heating component 2 and preventing the shell 1 at the upper end of the heating component 2 from overheating and causing scalding to the user. The upper silicone 51 assembly 5 includes an upper silicone 51 installed on the heating component 2 and an upper bracket 52 provided between the upper silicone 51 and the bracket 15. The upper bracket 52 cooperates with the upper silicone 51 to seal the middle of the bracket 15 and the heating component 2. The upper bracket 52 is provided with an air vent 521 connected to the upper end of the double-layer insulation tube 4 so that the intake air flow can smoothly enter the double-layer insulation tube 4 to achieve a heat insulation effect. As a preferred solution, an upper cover silicone is also provided between the upper bracket 52 and the upper shell 13. 53, which not only strengthens the thermal insulation of the upper end of the heating component 2, but also improves the sealing inside the shell 1, ensuring the stability of the intake air flow.

In this embodiment, as shown in FIG. 4 , a lower silicone component 54 is provided at the lower end of the heating component 2 to prevent the heat in the heating component 2 from being lost from the lower end of the heating component 2 , thereby improving the thermal insulation effect of the heating component 2 and preventing the temperature inside the shell 1 from rising, thereby affecting the performance of the power supply component 3 in the shell 1 .

When the tobacco flue-curing machine heats and bakes the cigarettes in the accommodating space 231, residues such as tobacco ash and tar will be produced, and the residues at the bottom of the accommodating space 231 are not easy to clean. Over time, they are prone to produce odor and breed bacteria, affecting user experience and health.

In this embodiment, as shown in FIG8 , a residue bin 6 and a residue hole 7 connecting the residue bin 6 and the accommodating space 231 are further provided at the bottom of the heating assembly 2, and a residue tray 8 is detachably installed in the residue bin 6. When heating and baking cigarettes, residues such as residues and tar are generated, which will pass through the residue hole 7 at the bottom of the accommodating space 231 and fall into the residue tray 8 in the residue bin 6 to collect these residues, and then the residue tray 8 is removed through the detachable structure of the residue bin 6 and the residue tray 8 for cleaning and disinfection to ensure the cleanliness and sanitation of the tobacco curing machine.

In this embodiment, as shown in FIG3 , the smoke residue hole 7 is arranged at the center of the bottom of the accommodating space 231, so that the residue in the accommodating space 231 can easily fall into the smoke residue tray 8 in the smoke residue bin 6, thereby ensuring the cleanliness of the accommodating space 231 and avoiding heating the residue again to cause adverse effects. As a preferred solution, the size of the smoke residue hole 7 is set larger and can be passed through by a cleaning brush. The larger aperture ensures that the residue can smoothly fall into the smoke residue tray 8, and the smoke residue hole 7 is not easily blocked. Moreover, the residue adhering to the accommodating space 231 can be brushed to the smoke residue hole 7 with a cleaning brush, and passed to the smoke residue tray 8, thereby improving the cleanliness of the tobacco curing device.

In this embodiment, as shown in FIG8 , a locking device is provided between the cigarette residue bin 6 and the cigarette residue tray 8. The device is arranged to lock the residue tray 8 in the residue bin 6, ensure that the residue tray 8 is installed in the set position of the residue bin 6 and the stability of the installation, ensure that all the residues fall into the residue tray 8, and avoid the risk of the residue tray 8 being moved out and causing the residue inside to be exposed. As a preferred solution, the locking device is a magnetic suction component arranged between the residue bin 6 and the residue tray 8, including: a first magnetic suction component 81 arranged on the residue bin 6 and a second magnetic component 82 arranged on the residue tray 8. Through the magnetic attraction between the first magnetic suction component 81 and the second magnetic component 82, the residue tray 8 can be installed firmly when it is installed in the residue bin 6, and the residue tray 8 can be accurately installed and locked, effectively avoiding the accidental removal of the residue tray 8. Of course, in other embodiments, the locking device can be set to other structures to lock the residue tray 8 in the residue bin 6 and prevent it from falling out easily, such as a snap assembly.

In this embodiment, as shown in FIG8 , a handle 83 is further provided on the outer side of the smoke residue tray 8, so that the user can smoothly take out the smoke residue tray 8 from the smoke residue bin 6 to clean the smoke residue tray 8. As a preferred solution, the smoke residue tray 8 is arranged on the bracket 15, on the inner side of the upper shell 13 and the lower shell 14, and the upper shell 13 and the lower shell 14 need to be disassembled to take out the smoke residue tray 8. The upper shell 13 and the lower shell 14 are arranged on the outer side of the smoke residue tray 8 so that it will not be easily transferred out, and at the same time, it is prevented from accidentally pulling out the smoke residue tray 8 and falling off the tobacco curing device to cause the smoke residue tray 8 to fly out.

In this embodiment, as shown in FIG. 4 , the ash bin 6 is connected to the air passage 41 at the lower end of the double-layer heat-insulated tube 4, so that the intake airflow passes through the ash bin 6 and then enters the accommodating space 231 through the ash hole 7, which serves as the inner air inlet hole, and can effectively prevent the ash and other residues from blocking the inner air inlet 232. At the same time, the ash tray 8 and the ash bin 6 are sealed during installation to prevent the outside air from directly entering the accommodating space 231 from the ash tray 8 and the air in the ash tray 8, thereby affecting the intake airflow and causing the heat insulation function of the double-layer heat-insulated tube 4 to fail.

The power supply component 3 is arranged in the housing 1, and is electrically connected to and controlled by the second heating part 22 and the first heating part 21. As a preferred solution, the power supply component 3 is arranged at the bottom of the cigarette residue bin 6. The power assembly 3 is kept away from the heating assembly 2, which effectively prevents the heat generated by the heating assembly 2 from causing the power assembly 3 to overheat. The setting of the cigarette residue bin 6 can prevent the tar liquid generated by baking cigarettes from flowing into the power assembly 3, which may cause the power assembly 3 to short-circuit or cause other faults.

The above is only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
