Description

Technical Field

[0001] This invention relates to the field of novel tobacco products, and in particular to an electronic pipe. Background Technology

[0002] When cigarettes burn, the core temperature of the combustion cone can reach thousands of degrees Celsius. Such high temperatures cause the smoke produced by cigarettes to contain hundreds of carcinogenic substances, which are extremely harmful to the human body. Heated tobacco products, on the other hand, do not require the burning of cigarettes. They use heated tobacco to produce smoke that can be inhaled. Because the heating temperature is much lower than the temperature required for ignition, heated tobacco products contain fewer harmful substances in their smoke and are becoming increasingly popular with consumers.

[0003] Currently, low-temperature heated non-combustible cigarette products are a research hotspot both domestically and internationally. The inhalation of these novel tobacco products requires a specialized heater; however, these heaters often suffer from uneven heating and localized overheating. For example, Chinese patent CN207969657U discloses a pipe-shaped inhalation device and an electronic pipe. The heater used consists of a heating chamber within the pipe body, containing heating elements that are electrically connected to a power source. A spiral airflow channel is located on the outer periphery of the heating chamber, starting from the top, spiraling downwards along the chamber's axis, and extending to the bottom. Ventilation holes are located on the bottom wall of the heating chamber, through which the airflow channel communicates with the chamber. The heating elements are evenly distributed on the inner wall of the heating chamber. Because this heater uses an insert-type heating element, it also suffers from uneven heating, localized overheating, and increased release of harmful gases from the tobacco. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of uneven heating of tobacco, leading to localized overheating. This invention provides an electronic pipe that can heat tobacco evenly, preventing localized overheating and reducing the release of harmful gases.

[0005] To address the aforementioned technical problems, one embodiment of the present invention discloses an electronic cigarette pipe, comprising:

[0006] The pipe body has a first cavity inside, and an air inlet is provided on the pipe body;

[0007] The pipe stem is connected to the pipe body, and the mouthpiece is set on the pipe stem;

[0008] At least one airflow heating microtube is disposed in the first cavity. The airflow heating microtube is connected to the air inlet and is used to heat the gas introduced into the airflow heating microtube through the air inlet.

[0009] The heating chamber is used to hold the tobacco material. The heating chamber is connected to the airflow heating microtube and the mouthpiece.

[0010] The power supply is electrically connected to the airflow heating microtube.

[0011] Using the above technical solution, gas is introduced into the airflow heating microtube through the air inlet. The airflow heating microtube heats the gas. During inhalation, the gas moves in the airflow heating microtube and enters the heating chamber that is connected to the airflow heating microtube. It then penetrates the tobacco to be heated in the heating chamber and finally enters the smoker's mouth through the mouthpiece. Using hot air to heat the tobacco has good heating uniformity, avoids local overheating, and reduces the release of harmful gases from the tobacco.

[0012] As one specific implementation, the airflow heating microtube is spiral, vortex, or Z-shaped.

[0013] As one specific implementation, the gas inside the airflow heating microtube is heated to a temperature greater than 100°C.

[0014] As one specific implementation, the cross-section of the airflow heating microtube is circular, and its inner diameter is less than 3mm.

[0015] As one specific implementation, the volume of the airflow heating microtube is greater than 10 ml.

[0016] As one specific implementation method, the airflow heating microtube is made of a high-temperature resistant material.

[0017] As one specific implementation, a heating element for heating the airflow heating microtube is provided on the inner wall and / or outer wall of the airflow heating microtube, and the heating element is electrically connected to a power source.

[0018] As one specific implementation, the air inlet end of the airflow heating microtube is connected to the air inlet through a one-way valve.

[0019] As one specific implementation method, the heating chamber is made of metal.

[0020] As one specific implementation, the heating chamber can be detachably installed inside the pipe body and / or pipe handle.

[0021] In one specific embodiment, a control component for controlling the electronic pipe switch is provided on the upper part of the first cavity. The control component includes:

[0022] The button is located on the outside of the electronic cigarette holder;

[0023] The button panel is located inside the button and is electrically connected to the electronic cigarette. The button controls the electronic cigarette's on / off state by connecting or disconnecting from the button panel.

[0024] The button base is located above the first cavity and is used to support and fix the button plate. The button base is provided with multiple vent holes, each of which is connected to the air inlet and the airflow heating microtube.

[0025] As one specific embodiment, a sealing assembly for sealing the first cavity is provided on the upper part of the first cavity.

[0026] As one specific implementation, the pipe stem and the pipe body are detachably connected.

[0027] As one specific implementation, it includes a wireless charging component and / or a wired charging component.

[0028] As one specific implementation, it also includes a control system, which is connected to the charging component and the control component.

[0029] As one specific implementation, the control system is also connected to an indicator device, which is disposed on the outer surface of the electronic pipe.

[0030] An embodiment of the present invention also discloses a method for generating aerosols, comprising the following steps:

[0031] When the electronic pipe is turned on, the airflow heating microtube heats the gas already present in the airflow heating microtube, and the heating chamber absorbs the heat to preheat the tobacco.

[0032] After the preheating time is reached, inhale the electronic pipe. The heated gas in the airflow heating microtube moves to the heating chamber, penetrates the tobacco, heats the tobacco, and generates an aerosol.

[0033] At the same time, as you inhale, the gas outside the electronic pipe enters the airflow heating microtube through the air inlet; the airflow heating microtube heats the gas entering the gas heating microtube to a set temperature, and the heated gas then moves to the heating chamber to heat the tobacco and form an aerosol.

[0034] Repeat the steps above.

[0035] The above technical solution utilizes air-heated microtubes to heat the gas to a set temperature. Then, during suction, the gas is heated along with the smoke material in the heating chamber via air-heated conveyor. Using hot air to heat the smoke material ensures good heating uniformity, prevents localized overheating, and reduces the release of harmful gases. Furthermore, the use of microtubes to heat the airflow results in high heating efficiency. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0048] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0049] One embodiment of the present invention discloses an electronic pipe, such as Figure 1-6 As shown, the device includes a pipe body 10, a pipe stem 20, and an aerosol generating assembly 30, and also includes a power supply 40. The pipe body 10 has a first cavity 11 and an air inlet. The pipe stem 20 is connected to the pipe body 10 and has a mouthpiece 21. The aerosol generating assembly 30 includes at least one airflow heating microtube 33 and a heating chamber 34. The airflow heating microtube 33 is disposed in the first cavity 11 and is connected to the air inlet for heating the gas introduced into the airflow heating microtube 33 through the air inlet. The heating chamber 34 is used to hold tobacco 60 and is connected to both the airflow heating microtube 33 and the mouthpiece 21. The power supply 40 includes a power supply 41, which is electrically connected to the airflow heating microtube 33 to provide electrical energy for heating the airflow heating microtube 33.

[0050] Using the above technical solution, gas is introduced into the airflow heating microtube 33 through the air inlet. The airflow heating microtube 33 heats the gas. During inhalation, the gas moves within the airflow heating microtube 33 and enters the heating chamber 34, which is connected to the airflow heating microtube 33. It then permeates the tobacco 60 to be heated in the heating chamber 34, heating the tobacco 60 and forming an aerosol. Finally, the aerosol enters the smoker's mouth through the mouthpiece 21. In this embodiment, using hot air to heat the tobacco 60 provides good heating uniformity, prevents localized overheating, and reduces the release of harmful gases.

[0051] In this embodiment, there are no restrictions on the number and spatial arrangement of the airflow heating microtubes 33 located in the first cavity 11. They can be in an ordered or disordered spatial distribution form, such as a spiral, a vortex, a Z-shape, or a layered stack. The number of airflow heating microtubes 33 can be one or multiple; if there are multiple microtubes, they can be arranged according to one of the above-mentioned suitable spatial distribution forms.

[0052] The cross-sectional shape of the airflow heating microtube 33 is not limited and can be square, elliptical, circular, etc. As a specific embodiment, the airflow heating microtube 33 has a circular cross-section with an inner diameter of less than 3 mm. The cross-sectional radius of the airflow heating microtube 33 is less than 3 mm, which can make the heat transfer efficiency higher.

[0053] Furthermore, the volume of the airflow-heated microtube 33 is greater than 10ml, ensuring that the amount of gas within it can meet the needs of a single suction session. The specific volume of the airflow-heated microtube 33 can be determined based on the suction habits of the user, or it can be determined based on the suction habits or suction experience of different users.

[0054] As mentioned above, the inner diameter and volume of the airflow heating microtube 33 are relatively small, which can also improve the gas heating efficiency and enable the gas entering the airflow heating microtube 33 to quickly reach the temperature required for heating the tobacco.

[0055] Furthermore, the airflow heating microtube 33 is made of a high-temperature resistant material, such as metal or high-temperature resistant plastic. Heating elements for heating the airflow heating microtube 33 are provided on the inner and / or outer walls of the airflow heating microtube 33. These heating elements are electrically powered heating elements, including resistance wires and carbon films. The heating elements are electrically connected to the power supply 41 to efficiently heat the airflow heating microtube 33.

[0056] Specifically, the heating element can be applied to the inner wall of the airflow heating microtube 33 by means of coating or other methods, or it can be wrapped around the outer wall of the airflow heating microtube 33. When applied to the outer wall, the thermal conductivity of the airflow heating microtube 33 should be relatively large in order to achieve efficient heat transfer.

[0057] Furthermore, the gas inside the airflow heating microtube 33 is heated to a temperature greater than 100°C. Specifically, the air inlet of the airflow heating microtube 33 is connected to the air inlet via a one-way valve 32, which prevents the gas inside the airflow heating microtube 33 from overflowing.

[0058] Furthermore, a heat insulation layer is provided on the outside of the airflow heating microtube 33 to prevent the heat from the airflow heating microtube 33 from being transferred to the electronic pipe, causing it to become hot, or to other electronic components inside the electronic pipe, affecting the performance of those components. For example... Figure 3 and Figure 5As shown, when the airflow heating microtube 33 is adjacent to components such as the power supply 41, a first heat insulation layer 13 and a second heat insulation layer 14 are respectively arranged from the inside to the outside along the radial direction of the first cavity 11.

[0059] Furthermore, the heating chamber 34 is made of metal. When the electronic pipe is activated, it is in a preheating state. During the preheating process, the gas inside the airflow heating microtube 33 is heated. At this time, there is no inhalation, and the gas inside the airflow heating microtube 33 does not flow strongly. The heating chamber 34 can transfer heat to preheat the tobacco 60 located inside it. The specific location of the heating chamber 34 in the electronic pipe can be inside the pipe body 10, inside the pipe stem 20, or at the connection between the pipe body 10 and the pipe stem 20. Specifically, when the heating chamber 34 is located inside the pipe body 10, the airflow heating microtube 33 can be arranged vertically superimposed on the heating chamber 34. Alternatively, the heating chamber 34 can also be located in the middle of the first cavity 11, with the upper and lower ends of the heating chamber 34 connected to the gas heating microtube and the mouthpiece 21, respectively.

[0060] When the heating chamber 34 is installed in the pipe handle 20, the specific structure can be as follows: Figure 3 and Figure 5 As shown, a second cavity 12 is provided in the pipe stem 20, and a heating chamber 34 is detachably installed in the second cavity 12. A through hole is provided at the bottom of the heating chamber 34, which communicates with the end of the airflow heating microtube 33. The gas heated by the airflow heating microtube 33 seeps into the tobacco 60 through the through hole of the heating chamber 34, heating the tobacco 60 to form an aerosol, which is then provided to the user for inhalation through the mouthpiece 21.

[0061] Furthermore, the heating chamber 34 is detachably connected to the pipe stem 20, allowing for the selection of different sizes of heating chambers 34 based on the shape and dimensions of the heated tobacco 60, thus improving the applicability of the electronic pipe. Correspondingly, the pipe stem 20 is detachably connected to the pipe body 10, with the connection method including at least one of magnetic, threaded, or snap-fit ​​connections. This detachable connection between the pipe stem 20 and the pipe body 10 makes adding tobacco 60 to the heating chamber 34, cleaning the heating chamber 34, or replacing the heating chamber 34 more convenient.

[0062] The tobacco material 60 involved in the embodiments of this application is not limited in its specific shape and composition. For example, it can be fine particles, pellets, strips, belts or sheets containing tobacco leaves, tobacco leaves, reconstituted tobacco, extruded tobacco and expanded tobacco (such as cigarettes, tobacco extract, tobacco granules, etc.).

[0063] As one specific implementation method, see attached... Figure 3-6As shown, a sealing assembly for sealing the first cavity 11 is provided on its upper part. Specifically, this includes a sealing cap 15 covering the upper part of the first cavity 11, and a sealing ring 16 whose edge is pressed against the sealing cap 15. The sealing ring 16 is tightly connected to the upper part of the pipe body 10, and the tight connection can be achieved through threaded connection, interference fit, etc. Figures 3-6 As shown, within the independent space enclosed by the sealing plate and the sealing ring 16, a control circuit board 54 for controlling the entire electronic pipe can be installed to protect the control circuit board 54.

[0064] Specifically, the sealing cap 15 has a hollow channel in the middle, and a one-way valve 32 is installed in the channel. The upper part of the one-way valve 32 is connected to the air inlet, and the lower part is connected to the airflow heating microtube 33.

[0065] In one specific embodiment, a control component 50 for controlling the electronic pipe switch is provided on the upper part of the first cavity 11. Specifically, the control component 50 is located above the sealing cover 15 and connected to the sealing cover 15.

[0066] Furthermore, the control component 50 includes a button base 53, a button plate 52, and buttons 51. As a specific embodiment, such as... Figure 3 and Figure 4 As shown, the button base 53 is connected to the sealing cover 15 to support and fix the button plate 52. Specifically, the button base 53 includes a support plate, and a cylindrical body is connected to the lower part of the support plate. Multiple through holes are provided on the side wall of the cylindrical body near the support plate. The cylindrical body is hollow, so the button base 53 fits onto the channel of the sealing cover 15 through the cylindrical body. The height of the cylindrical body is lower than the height of the channel of the sealing cover 15, and it does not completely fit against the side wall of the cylindrical body, allowing the through holes on the cylindrical body to communicate with the one-way valve 32 connected to the channel of the sealing cover 15. This allows air from the air inlet to enter the one-way valve 32 through the through holes on the button base 53.

[0067] The button panel 52 is securely connected to the top of the button base 53, specifically using methods such as bolts, adhesive, or snap-fit. The button panel 52 has a circuit board for controlling the opening and closing of the electronic cigarette.

[0068] Button 51 is located above the electronic cigarette holder, on the top of button plate 52 and electrically connected to button plate 52. The electronic cigarette holder is switched on or off by connecting or disconnecting button 51 and button plate 52.

[0069] Specifically, the air inlet is located at the top of the electronic cigarette holder. One specific structure disclosed in this embodiment is as follows: Figures 1-6As shown, an air intake mesh plate 31 is provided on the outer side of the button 51. The air intake mesh plate 31 has an inverted U-shaped annular structure, and ventilation holes are provided on the top and side walls of the air intake mesh plate 31. The button plate 52 and the button base 53 are both disposed within the annular space of the air intake mesh plate 31. The ventilation holes of the air intake mesh plate 31 are connected to the through holes of the cylinder of the support plate, so that the gas entering through the air intake mesh plate 31 can pass through the through holes on the cylinder of the support plate into the one-way valve 32, and then into the airflow heating microtube 33. In one case, the upper part of the button 51 is transitionally connected to the upper part of the air intake mesh plate 31 to form the appearance of the upper part of the electronic pipe body 10.

[0070] Furthermore, an indicator device 17 can also be installed on the electronic pipe, such as... Figures 3-6 As shown, the indicator 17 is disposed between the sealing ring 16 and the air intake grille 31, and is connected to the control circuit board 54. The indicator 17 can be used to indicate information such as the battery level of the electronic cigarette, heating time, and reminders. The indication can be provided through changes in light intensity or color, or by flashing lights. Alternatively, vibration or other reminder methods can also be used.

[0071] Furthermore, it also includes a charging device, which includes a wireless charging component and / or a wired charging component. When implementing wireless charging, the wireless charging component includes a charging induction coil 43 disposed at the bottom of the pipe body 10, and a charging base disposed outside the pipe that matches the charging induction coil 43. A charging port 42 is provided on the pipe body 10 or the pipe handle 20 to implement wired charging.

[0072] In use, press button 51 to start the electronic pipe and enter the preheating mode. The electronic components on the airflow heating microtube 33 heat the airflow heating microtube 33, thereby heating the gas already present in the airflow heating microtube 33. At the same time, the heated gas transfers heat to the heating chamber 34, and the heating chamber 34 absorbs heat to preheat the tobacco 60. After reaching the preheating temperature, you can start smoking. The heated gas enters the heating chamber 34 through the through hole at the bottom of the heating chamber 34, seeps into the tobacco 60, heats the tobacco 60 to generate an aerosol, and reaches the smoker's mouth through the mouthpiece 21.

[0073] As you inhale, gas continuously enters the airflow heating microtube 33 from the outside of the electronic cigarette. The specific gas flow path is as follows: Figure 5 and Figure 6As shown, gas enters through the through-hole on the air inlet mesh plate 31, then passes through the hole on the side wall of the button plate 52 into the one-way valve 32, and then enters the airflow heating microtube 33 through the one-way valve 32. The gas is heated in the airflow heating microtube 33 and moves within it during inhalation, entering the heating chamber 34 which is connected to the airflow heating microtube 33. The hot gas heats the tobacco 60, and then enters the smoker's mouth through the mouthpiece 21. This process is repeated until inhalation is complete. In this embodiment, the airflow heating microtube is used to heat the gas, resulting in higher heating efficiency; heating the tobacco with hot air ensures good heating uniformity and prevents localized overheating, thus reducing the release of harmful gases.

[0074] While the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the invention to these descriptions. Various changes in form and detail can be made by those skilled in the art, including several simple deductions or substitutions, without departing from the spirit and scope of the invention.
