Description

Technical Field

[0001] This invention relates to the field of electronic cigarette technology, specifically to an electronic cigarette heating element, its manufacturing method, and an electronic cigarette. Background Technology

[0002] The main components of an electronic cigarette include a heater, a power supply, an e-liquid cup, and a filter. It is an electronic device that uses a heater to heat e-liquid to release vapor.

[0003] Current e-cigarette heating elements consist of a heating wire and an e-liquid wicking material, mostly made of absorbent cotton or ceramic. The heating wire is inserted into the wicking material, and the heat generated by the wire is transferred to the material, which then absorbs and heats the e-liquid. However, this type of heater has the following disadvantages: 1. Poor wicking effect. For example, when using absorbent cotton, its wicking effect is unstable. When using ceramic, the ceramic's adsorption capacity is insufficient, resulting in poor microporous absorption and wicking performance, thus affecting the e-cigarette's flavor. 2. Current wicking materials have long heating times and poor heat retention, requiring continuous heating from the heating wire. This accelerates the e-cigarette's battery consumption, leading to short battery life and inconvenience. Furthermore, the continuous heating of the heating wire also negatively impacts its lifespan.

[0004] Furthermore, although e-cigarettes differ from traditional cigarettes, their e-liquid still contains extracts of harmful substances. Excessive consumption can still be harmful to the body. Traditional cigarettes, once burned out, allow smokers to abstain from smoking for a period (the time between burning out and smoking the next cigarette), thus controlling their intake. However, e-cigarette e-liquid can last for a long time. If smokers do not consciously control their intake with each puff, the amount of smoke inhaled per puff is greater than that of a single traditional cigarette. Over time, long-term e-cigarette users inhale significantly more smoke than traditional cigarette users, which is extremely detrimental to their health and hinders public health efforts. Currently, e-cigarettes do not offer this intake control feature. Summary of the Invention

[0005] The present invention aims to provide an electronic cigarette heating element, its manufacturing method, and an electronic cigarette, so as to improve the heat absorption capacity of the heating element, reduce power consumption, improve battery life, and increase the service life of the heating wire.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an electronic cigarette heating component, comprising a heating wire, a housing, and an oil-conducting material located within the housing, the oil-conducting material containing graphene, the housing comprising a heat-insulating sidewall, an oil inlet end, and an oil outlet end, the oil inlet end and the oil outlet end being located at opposite ends of the heat-insulating sidewall; one end of the heating wire passes through the housing and is inserted into the oil-conducting material.

[0007] The principle and advantages of this solution are as follows: When heating the e-liquid, the oil-conducting material contains graphene, which has good adsorption and desorption properties. Graphene is a porous material, so it has better oil-conducting performance than traditional oil-conducting materials. It also has more oil storage space inside, which has good oil storage performance, thereby improving the oil-conducting and oil-storing performance of e-cigarettes.

[0008] Meanwhile, graphene has excellent thermal conductivity. The heat generated by the heating wire is transferred to the oil-conducting material. Since the oil-conducting material contains graphene, it can quickly transfer the heat and heat up rapidly, thereby reducing the heating time of the heating wire. At the same time, the heat-insulating sidewall can keep the oil-conducting material warm, so that the temperature of the oil-conducting material will not drop rapidly after being heated, thus extending the temperature maintenance time. The heating wire does not need to be continuously heated, which helps to improve the service life of the heating wire and reduce power consumption.

[0009] In addition, the rapid and uniform heating of the wicking material also helps to improve the uniform and rapid heating of the e-liquid. Compared with existing wicking materials, it avoids the problem of burning caused by excessive local heating of the e-liquid, which is beneficial to improving the flavor of e-cigarettes.

[0010] Preferably, as an improvement, both the inlet and outlet ends are provided with oil passage holes. Thus, e-liquid can enter the wicking material through the oil passage hole at the inlet end, and the vapor produced by heating the e-liquid then exits through the oil passage hole at the outlet end.

[0011] Preferably, as an improvement, the heating wire is inserted into the wicking material from the heat-insulating sidewall. This prevents the heating wire from being inserted into the casing from the outlet end, thus avoiding premature heating of the e-liquid before it enters the wicking material. Simultaneously, the absence of the heating wire from the outlet end prevents the vapor exiting from the outlet from being reheated. This ensures that the entire e-liquid heating process is completed within the wicking material.

[0012] Preferably, as an improvement, the oil-guiding material is composed of graphene particles, graphene sheets, or stacked graphene filaments. Thus, the inner core can have different macroscopic forms.

[0013] To achieve the above objectives, the present invention adopts the following technical solution: an electronic cigarette, comprising a housing, wherein the housing is provided with a power supply chamber, an e-liquid chamber, a heating chamber, an e-liquid inlet chamber, and an e-liquid outlet chamber; any of the above-mentioned electronic cigarette heating components are located in the heating chamber; The power supply chamber contains a power source, and the heating wire is located on the outside of the cover and connected to the power source. The oil inlet chamber is located on one side of the oil inlet end, and an oil inlet pipe connects the oil inlet chamber and the e-liquid chamber. The oil outlet chamber is located on one side of the oil outlet end; The housing is equipped with a suction nozzle that communicates with the oil outlet chamber.

[0014] The principle and advantages of this design are as follows: the power supply chamber holds the power source, the e-liquid chamber holds the e-liquid, the heating chamber houses the electronic cigarette's heating element, and the inlet chamber is located between the heating chamber and the e-liquid chamber. E-liquid from the e-liquid chamber enters the inlet chamber through the inlet tube, and then enters the heating element in the heating chamber. The heated e-liquid is converted into vapor, which enters the outlet chamber and is inhaled through the mouthpiece.

[0015] The heating element in this electronic cigarette has a heat preservation function, and graphene can quickly transfer the heat generated by the heating wire, which has the advantage of rapid heating. Therefore, the heating wire does not need to be continuously heated, which helps to improve the service life of the heating wire and reduce power consumption.

[0016] Preferably, as an improvement, a fixed shell is fixedly connected to the outer side of the housing, and a sliding cavity is provided between the fixed shell and the housing. A sliding member is slidably connected in the sliding cavity, and a sliding rod is fixedly connected to the sliding member. The sliding rod is inserted into the oil inlet cavity, and a sliding piece is fixedly connected to one end of the sliding rod located in the oil inlet cavity. The sliding piece can slide at the end of the oil inlet pipe. An elastic element is connected between the end of the sliding cavity near the nozzle and the end of the sliding component, and the nozzle and the sliding cavity equipped with the elastic element are in communication.

[0017] Therefore, with this solution, when a smoker starts smoking, under the action of suction, the e-liquid in the e-liquid chamber enters the e-liquid chamber through the e-liquid inlet tube, and then enters the e-liquid guide material through the e-liquid inlet end. The e-liquid is heated into smoke, and then comes out from the e-liquid outlet end into the e-liquid outlet chamber. The smoke is then inhaled into the mouth through the mouthpiece.

[0018] During each puff of smoke, because the mouthpiece is connected to a sliding cavity equipped with an elastic element, some of the gas in the sliding cavity is drawn into the mouth, thus consuming some of the gas in the sliding cavity. This reduces the air pressure inside the sliding cavity, causing the sliding element to slide under the influence of external atmospheric pressure and compress the elastic element until the sum of the pressure exerted by the elastic element on the sliding element and the gas pressure inside the sliding cavity equals the external air pressure acting on the sliding element. Only then does the sliding element stop sliding. Therefore, with each puff of smoke, the sliding element moves a certain distance, and through a sliding rod, it drives a sliding plate to move a certain distance. The sliding plate gradually moves to the end of the oil inlet pipe and gradually seals the end of the oil inlet pipe, thus gradually reducing the size of the oil outlet and the amount of oil output from the oil inlet pipe. After the heating wire finishes heating the wicking material, to save energy and extend the wire's lifespan, the heating stops. The e-liquid is then heated by the temperature stored in the wicking material. As smoking continues, the temperature of the wicking material gradually decreases, and the e-liquid output from the inlet tube also gradually decreases. This ensures the output adapts to the temperature changes of the wicking material, preventing a situation where the output remains constant despite a decrease in material temperature. This avoids the problem of insufficient heating of the e-liquid, thus guaranteeing effective heating. Simultaneously, the gradually decreasing e-liquid output reduces the amount inhaled by the smoker, helping to minimize harm. Furthermore, as smoking continues, the output gradually decreases until the sliding plate completely seals the inlet tube. At this point, the inlet tube stops supplying e-liquid, and the smoker notices a significant decrease in the taste and purity of the vapor inhaled. At this point, the smoker stops smoking, thus achieving the goal of controlling the amount inhaled and reducing harm.

[0019] When the smoker stops smoking, the slider is no longer subject to suction and gradually returns to its original position under the action of the elastic element. The slider then drives the sliding plate to slide slowly in the opposite direction via the sliding rod, and the oil inlet is automatically reopened. In this way, when the smoker stops smoking and waits for several tens of minutes or hours before smoking again, the electronic cigarette can resume normal operation.

[0020] Preferably, as an improvement, the fixed shell is provided with an air inlet, which is connected to a sliding cavity with an elastic element.

[0021] Therefore, when the elastic element pushes the sliding element to slowly reset, the air inlet can replenish the gas into the sliding cavity, avoiding the continuous negative pressure in the sliding cavity that prevents the elastic element from pushing the sliding element to reset. Thus, the air inlet facilitates the elastic element to push the sliding element to slowly reset.

[0022] Preferably, as an improvement, the end of the slider away from the elastic element is in communication with the outside air. This ensures that the end of the slider away from the elastic element is in contact with the outside and subjected to atmospheric pressure.

[0023] To achieve the above objectives, the present invention adopts the following technical solution: a method for manufacturing a heating element for an electronic cigarette, comprising the following steps: S1. Take a cylindrical heat-insulating sidewall, an oil inlet end and an oil outlet end, and the heat-insulating sidewall is provided with holes for the heating wire to pass through; S2. Insert the heating wire into the heat insulation sidewall, then prepare the graphene slurry, place the heat insulation sidewall vertically on the template, fill the cylinder of the heat insulation sidewall with the graphene slurry, and place it in a drying oven to dry and cool. S3. Remove the heat insulation sidewall from the template and install the oil inlet and outlet ends at both ends of the heat insulation sidewall.

[0024] Thus, the above scheme enables the manufacturing of the heating element for electronic cigarettes. In step S2, the heating wire is first inserted into the heat-insulating sidewall. After the graphene slurry solidifies, the heating wire is automatically fixed within the slurry. The heat-insulating sidewall is then placed vertically on a template, and the graphene slurry is filled into its cylinder. The template seals the bottom of the heat-insulating sidewall to prevent leakage. After drying, the graphene slurry solidifies and forms a solidified structure within the heat-insulating sidewall. There is no need to separately add the wicking material to the heat-insulating sidewall; the sidewall and wicking material automatically connect, simplifying the manufacturing process. After the heat-insulating sidewall and wicking material are integrated, step S3 involves installing an inlet and an outlet at both ends of the heat-insulating sidewall. These inlet and outlet ends seal the ends of the heat-insulating sidewall, completing the manufacturing of the heating element for the electronic cigarette.

[0025] Preferably, as an improvement, the heat-insulating sidewall is cylindrical or square. Therefore, the heat-insulating sidewall can be designed as a cylinder or a square tube according to actual needs. Attached Figure Description

[0026] Figure 1 This is a schematic diagram of the structure of an electronic cigarette.

[0027] Figure 2 for Figure 1 Sectional view of AA. Detailed Implementation

[0028] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: housing 1, mouthpiece 2, power supply chamber 3, e-liquid chamber 4, oil outlet chamber 5, oil guiding material 6, oil outlet end 7, oil inlet end 8, heating wire 9, oil inlet pipe 10, oil inlet chamber 11, sliding plate 12, sliding rod 13, sliding component 14, fixed shell 15, air supply hole 16, connecting hole 17, heat insulation sidewall 18.

[0029] The basic implementation examples are as follows: Figures 1-2The image shows a heating element for an electronic cigarette, comprising a heating wire 9, a housing, and an oil-conducting material 6 located within the housing. The oil-conducting material 6 contains graphene and can be made of pure graphene or a mixture of other materials (such as ceramic materials) and graphene. In this embodiment, the material is pure graphene and is in granular form. The granular graphene material is aggregated together, and the gaps between the particles form the oil-conducting channels. Larger particles have larger gaps, and smaller particles have smaller gaps. In this embodiment, the gaps between the oil-conducting channels are less than 100 micrometers.

[0030] The enclosure in this embodiment includes a heat-insulating sidewall 18, an oil inlet end 8, and an oil outlet end 7. The heat-insulating sidewall 18 can be directly made of heat-insulating material, such as a heat-insulating sleeve made of asbestos or fiberglass, or it can be made of conventional metal material first, and then a layer of heat-insulating material is filled into the inner wall of the heat-insulating sidewall 18. The oil inlet end 8 and the oil outlet end 7 are respectively fixed at both ends of the heat-insulating sidewall 18, and the fixing method can be snap-fit ​​or fixed by screws. Both the oil inlet end 8 and the oil outlet end 7 are metal sheets with high temperature resistance and wear resistance. The enclosure is filled with an oil-guiding material 6.

[0031] The heat-insulating sidewall 18 is provided with a through hole, and one end of the heating wire 9 passes through the through hole of the heat-insulating sidewall 18 and is inserted into the oil-conducting material 6. Both the oil inlet end 8 and the oil outlet end 7 are provided with oil passage holes, the diameter of which is 0.1 mm.

[0032] Of course, in other embodiments, the graphene in the oil-guiding material 6 may not be graphene particles. Graphene material has a layered structure microscopically, but can also take other shapes macroscopically, such as being made of stacked graphene sheets or graphene filaments. When the graphene material is in sheet form, the graphene sheets are stacked, and the spaces between the graphene sheets form oil-guiding channels. When the graphene material is in filament form, the graphene filaments can be filaments cut from sheet-like graphene, or filaments formed directly by a process, and the spaces between the individual graphene filaments form oil-guiding channels.

[0033] The shape of the heat-insulating sidewall 18 can be cylindrical, square, or any other cylindrical structure that can be enclosed.

[0034] This embodiment also discloses a method for manufacturing a heating element for an electronic cigarette, including the following steps: S1. A cylindrical heat-insulating sidewall 18, an oil inlet end 8, and an oil outlet end 7 are constructed. The heat-insulating sidewall 18 can be a cylindrical structure made by directly rolling heat-insulating material, or it can be a cylindrical structure made of rolled metal. A layer of heat-insulating material is bonded and filled into the inner layer of the metal layer. Both the oil inlet end 8 and the oil outlet end 7 are metal sheets. Oil passage holes are drilled on both the oil inlet end 8 and the oil outlet end 7 by laser drilling. Holes are drilled on the heat-insulating sidewall 18 for the heating wire 9 to pass through.

[0035] S2. Insert the heating wire 9 into the heat-insulating sidewall 18, then prepare a graphene slurry (a mixture of graphene particles and solvent). Place the cylindrical heat-insulating sidewall 18 vertically on the template, fill the cylinder of the heat-insulating sidewall 18 with the graphene slurry, and place it in a drying oven to dry for 2-3 hours at a temperature of 60-80℃. After drying, allow it to cool naturally. The graphene slurry solidifies to form an oil-conducting material 6, which is located in the heat-insulating sidewall 18.

[0036] S3. Remove the oil-conducting material 6 from the template along with the heat insulation sidewall 18. Install the oil inlet end 8 and the oil outlet end 7 at both ends of the heat insulation sidewall 18 respectively. Secure the oil inlet end 8 and the oil outlet end 7 to both ends of the heat insulation sidewall 18 respectively, or fix them together by welding or by screws.

[0037] This embodiment also discloses an electronic cigarette, including a housing 1. The housing 1 contains a power supply chamber 3, an e-liquid chamber 4, a heating chamber, an oil inlet chamber 11, and an oil outlet chamber 5. The power supply chamber 3 and the e-liquid chamber 4 occupy half of the space in the housing 1, while the heating chamber, oil inlet chamber 11, and oil outlet chamber 5 occupy the other half. A lithium battery is installed in the power supply chamber 3, and e-liquid is installed in the e-liquid chamber 4. The electronic cigarette's heating element is installed in the heating chamber. The heating element and the heating chamber can be fixed by snap-fit ​​or by screws. The oil inlet chamber 11 is located at the right end of the heating chamber, and the oil passage on the oil inlet end 8 communicates with the oil inlet chamber 11. The oil outlet chamber 5 is located on the left side of the oil outlet end 7, and the oil outlet chamber 5 communicates with the oil passage on the oil outlet end 7. A mouthpiece 2 is installed on the left side of the housing 1, and the mouthpiece 2 communicates with the oil outlet chamber 5.

[0038] In this embodiment, the heating wire 9 is located on the outside of the cover and connected to the power supply. The other end of the heating wire 9 is inserted into the oil-conducting material 6 inside the cover. An oil inlet pipe 10 connects the oil inlet chamber 11 and the e-liquid chamber 4, so that the e-liquid in the e-liquid chamber 4 can enter the oil inlet chamber 11 through the oil inlet pipe 10.

[0039] In this embodiment, a fixed shell 15 is fixedly connected (e.g., glued, snap-fitted, or fixed with screws) to the outer wall of the portion of the housing 1 where the heating chamber is located. A sliding cavity is provided between the inner wall of the fixed shell 15 and the side wall of the housing 1. The sliding cavity is located on the upper and lower sides of the housing 1. A sliding member 14 is slidably connected in the sliding cavity. In this embodiment, the sliding member 14 is U-shaped. The two sides of the sliding member 14 are located on the upper and lower sides of the housing 1, respectively. The right end of the sliding member 14 is a bent end. A sliding rod 13 is fixedly connected to the right end of the sliding member 14 by screws. The sliding rod 13 is inserted into the oil inlet cavity 11 and can slide at the right end of the oil inlet cavity 11. A sliding piece 12 is snap-fitted and fixedly connected to one end of the sliding rod 13 in the oil inlet cavity 11. The sliding piece 12 can slide at the end of the oil inlet pipe 10 and can seal the end of the oil inlet pipe 10. In order to reduce the leakage of e-liquid in the oil inlet cavity 11, an elastic seal, such as a seal made of rubber, can be installed at the rod hole portion at the right end of the oil inlet cavity 11.

[0040] The sliding cavity between the left end of the slider 14 and the left end of the fixed shell 15 is enclosed by the side wall and end of the fixed shell 15, so that the sliding cavity between the left end of the slider 14 and the left end of the fixed shell 15 will not be exposed, thus ensuring that the sliding cavity is in a relatively closed state.

[0041] An elastic element is connected between the end of the sliding cavity near the nozzle 2 and the end of the sliding member 14. The elastic element can be a compression spring or a sheet, which causes the sliding member 14 to have a rightward pressure. The nozzle 2 and the sliding cavity with the elastic element are connected, specifically through a pipe, or the housing 1 has a through hole, which allows the oil outlet cavity 5 to be connected to the sliding cavity.

[0042] In addition, the fixed shell 15 is provided with an air supply hole 16, which is connected to the sliding cavity with an elastic element. The diameter of the air supply hole 16 is 0.1 mm, which is much smaller than the diameter of the pipe (or through hole).

[0043] The right end of the slider 14, away from the elastic element, is in communication with the outside air. Specifically, the right end of the fixed shell 15 is provided with a connecting hole 17, which allows the right end of the slider 14 to communicate with the outside atmosphere.

[0044] The specific implementation process is as follows: In this scheme, the power supply provides power to the heating wire 9, which heats the oil-conducting material 6. Because the oil-conducting material 6 contains graphene, it rapidly transfers heat and heats up quickly, thus reducing the heating time of the heating wire 9. After the heating wire 9 has heated the oil-conducting material 6 for a period of time, such as 2-5 minutes, the power is disconnected via chip control or manually, stopping the heating wire 9 and allowing the oil-conducting material 6 to reach a certain temperature. Although the heating wire 9 stops heating, the heat-insulating sidewall 18 maintains the temperature of the oil-conducting material 6, preventing a rapid drop in temperature and extending the temperature maintenance time.

[0045] When a smoker starts smoking, the e-liquid in the e-liquid chamber 4 enters the e-liquid chamber 11 through the e-liquid inlet pipe 10, and then enters the e-liquid guide material 6 through the e-liquid inlet end 8. The e-liquid is heated into smoke by the e-liquid guide material 6, and then comes out from the e-liquid outlet end 7 and enters the e-liquid outlet chamber 5. The smoke is inhaled into the mouth through the mouthpiece 2.

[0046] Since the oil inlet pipe 10 is fully open when the smoker starts smoking, and the temperature of the oil guiding material is high, the amount of smoke drawn from the mouthpiece 2 is normal, which can ensure the taste of the smoker's first few puffs.

[0047] During each puff of smoke, because the mouthpiece 2 is connected to the sliding cavity equipped with an elastic element, some of the gas in the sliding cavity is drawn into the mouth. However, the diameter of the air supply hole 16 is small, so the gas supply to the sliding cavity is slow and cannot be replenished in a short time. As a result, some of the gas in the sliding cavity is consumed, and the air pressure in the sliding cavity decreases. Under the action of external atmospheric pressure, the sliding element 14 slides and squeezes the elastic element until the sum of the pressure of the elastic element on the sliding element 14 and the gas pressure in the sliding cavity equals the external air pressure on the sliding element 14. Only then does the sliding element 14 stop sliding to the left. Thus, with each puff of smoke, the sliding element 14 moves a certain distance to the left. The sliding element 14 drives the sliding plate 12 to move a certain distance to the left via the sliding rod 13. The sliding plate 12 gradually moves to the end of the oil inlet pipe 10 and gradually blocks the end of the oil inlet pipe 10, thereby gradually reducing the size of the outlet of the oil inlet pipe 10 and the amount of oil produced by the oil inlet pipe 10. After the heating wire 9 finishes heating the wicking material 6, to save electricity and extend its lifespan, the heating wire 9 stops heating. The e-liquid is then heated by the temperature stored in the wicking material. As the smoke continues, the temperature of the wicking material 6 gradually decreases. If the e-liquid intake remains constant, it will affect the normal heating of the e-liquid and cause it to turn into vapor. Therefore, as the number of puffs increases, the e-liquid output from the inlet tube 10 gradually decreases, allowing the output to adapt to the temperature changes of the wicking material 6. This avoids the situation where the temperature of the wicking material 6 decreases while the output remains constant, preventing the e-liquid from being adequately heated. This ensures the heating effect of the e-liquid. Simultaneously, the gradually decreasing e-liquid output reduces the amount inhaled by the smoker, thus minimizing harm.

[0048] In addition, as smoking continues, the amount of e-liquid produced gradually decreases until the sliding plate 12 completely seals the e-liquid inlet pipe 10. At this point, the e-liquid inlet pipe 10 no longer supplies e-liquid, and the smoker feels that the taste and purity of the smoke inhaled into their mouth have decreased significantly. At this point, the smoker stops smoking, and even if they force themselves to smoke, the e-liquid inlet pipe 10 will not produce e-liquid, thereby achieving the purpose of controlling the amount and reducing the harm to the smoker.

[0049] After the smoker stops smoking, the slider 14 is no longer subject to suction and gradually returns to its original position under the action of the elastic element. The slider 14, via the sliding rod 13, drives the sliding piece 12 to gradually and slowly slide in the opposite direction, and the oil inlet pipe 10 automatically opens again. This allows the electronic cigarette to resume normal operation after the smoker has stopped smoking and waits several tens of minutes or hours before smoking again. The air supply port 16 ensures that gas enters the sliding chamber when the slider 14 moves to the right, preventing negative pressure in the sliding chamber from preventing the slider 14 from moving to the right.
