Description

Technical Field

[0001] This invention relates to the field of smoking device structure technology, and in particular to an electronic smoking device capable of self-preventing dry burning. Background Technology

[0002] Existing aerosol generating devices include virtual cigarettes, electronic cigarettes, vaporizers, etc., which are mainly used to simulate the feeling of smoking without affecting health, for the purpose of quitting smoking or replacing cigarettes.

[0003] Currently, most e-cigarettes on the market heat and atomize e-liquid by supplying electricity to a heating element, thus producing vapor for consumers to inhale. During this process, if the e-liquid is reduced to a level insufficient to supply the heating element, it will dry-burn. This severely degrades the consumer experience. Furthermore, dry-burning at high temperatures can cause a chemical reaction in the small amount of residual e-liquid within the atomizing core, such as the wicking cotton or ceramic wicking material, producing harmful gases that can affect the consumer's health. Therefore, solving the dry-burning problem in e-cigarettes has become a popular research area.

[0004] Existing anti-dry-burning technologies mostly focus on electronic aspects and heating wire materials, while technologies that prevent dry burning through structural design are relatively rare. Furthermore, anti-dry-burning technologies based on electronics and heating wire materials require the use of sensors such as temperature sensors, capacitance sensors, thermistors, and humidity sensors, or the development of new materials such as TCR materials. These technologies are costly to implement, and the different threshold values ​​set for different e-liquids increase the probability of misjudgment, making them difficult to apply to various e-liquid systems. Summary of the Invention

[0005] The purpose of this invention is to provide a smoking device that can achieve a dry-burning prevention effect through structural design to save costs.

[0006] This invention provides a smoking device, including a mouthpiece, an oil reservoir, an oil guide, an atomizing element, and a control switch. The oil reservoir is used to hold e-liquid, the oil guide guides the e-liquid from the oil reservoir to the atomizing element for atomization, and the control switch is used to turn the atomizing element on and off. The device also includes:

[0007] An atomizing channel is connected to the nozzle, and the atomizing element is located in the atomizing channel;

[0008] The first air intake channel is connected to the atomizing channel, and the control switch is located in the first air intake channel;

[0009] The second air intake channel is connected to the atomizing channel. The second air intake channel has a conducting state and a closed state. When the second air intake channel is in the closed state, the control switch is turned on and the atomizing element is activated. When the second air intake channel is in the conducting state, the control switch is turned off and the atomizing element is not activated.

[0010] In one embodiment, the control switch is an airflow sensor. When the second air intake channel is closed and suction is being applied from the nozzle, the control switch opens when the pressure difference across it is not less than the trigger threshold. When the second air intake channel is open and suction is being applied from the nozzle, the control switch closes when the pressure difference across it is less than the trigger threshold.

[0011] In one embodiment, the second air intake channel is connected to the atomizing channel via the oil storage chamber. When the amount of e-liquid in the oil storage chamber is lower than a first threshold, the second air intake channel is in a connected state with the atomizing channel. When the amount of e-liquid in the oil storage chamber is greater than a second threshold, the second air intake channel is in a closed state without being connected to the atomizing channel. The second threshold is greater than or equal to the first threshold.

[0012] In one embodiment, the oil storage chamber has a first through hole and a second through hole. The first through hole is connected to the outside, and the second through hole is connected to the atomization channel. The first through hole, the oil storage chamber and the second through hole form the second air intake channel. A first liquid-proof and breathable membrane is provided at the first through hole, and a second liquid-proof and breathable membrane is provided at the second through hole.

[0013] When the e-liquid in the oil storage chamber blocks the first liquid-proof and / or second liquid-proof and breathable membrane, the second air intake channel is in a closed state; when the e-liquid in the liquid storage chamber does not block the first liquid-proof and breathable membrane and the second liquid-proof and breathable membrane, the second air intake channel is in a conductive state.

[0014] In one embodiment, the smoking device includes a carrier, in which the oil storage cavity and the air passage are formed. The air passage connects to the outside and the first through hole. The air passage, the first through hole, the oil storage cavity and the second through hole are sequentially connected to form the second air intake channel.

[0015] In one embodiment, the airway extends vertically and has a third through-hole communicating with the outside, the third through-hole being higher than the first through-hole.

[0016] In one embodiment, the third through hole is provided with a third liquid-proof and breathable membrane.

[0017] In one embodiment, the oil storage cavity is provided with oil storage cotton for storing e-liquid. The oil storage cavity has an oil guide hole, and the oil guide extends into the oil guide hole to guide the e-liquid in the oil storage cavity to the atomizing component for atomization. The oil guide hole is higher than the second through hole.

[0018] In one embodiment, the oil storage cavity is provided with an oil guide hole, the oil guide member extends into the oil guide hole and guides the e-liquid in the oil storage cavity to the atomizing member for atomization, and the second through hole is higher than the oil guide hole.

[0019] In one embodiment, the carrier is further formed with an atomizing cavity extending vertically, the oil storage cavity is arranged around the periphery of the atomizing cavity, the air passage is located outside the oil storage cavity, the atomizing cavity and the nozzle are connected to form the atomizing channel, and the atomizing element is inside the atomizing cavity;

[0020] The carrier includes a first cylindrical section, a second cylindrical section, and a third cylindrical section arranged from the inside out. The first cylindrical section encloses the atomizing chamber, the second cylindrical section and the first cylindrical section enclose the oil storage chamber, the third cylindrical section and the second cylindrical section enclose the air passage, and the third through hole is opened in the third cylindrical section. The second cylindrical section has the first through hole, the first cylindrical section has the second through hole, and the third cylindrical section has the third through hole.

[0021] The smoking device provided by this invention includes a first air intake channel and a second air intake channel. The first air intake channel and the second air intake channel are connected to the air passage structure of the atomizing channel, keeping the first air intake channel unobstructed. The second air intake channel has a conducting state and a closed state. When the second air intake channel is in the closed state, the control switch is opened to activate the atomizing component; when the second air intake channel is in the conducting state, the control switch is closed and the atomizing component is not activated. Therefore, the smoking device provided by this invention can achieve the technical effect of automatically stopping the smoking device to prevent dry burning when there is a lot of e-liquid in the device, keeping the second air intake channel in the closed state, thereby opening the control switch and activating the atomizing component; and automatically opening the second air intake channel to prevent the atomizing component from activating when the e-liquid is low or insufficient due to the operation of the device.

[0022] The smoking device provided by this invention can achieve the technical effect of preventing dry burning by setting a special air passage structure. This technical means can be implemented without electronic means, and has the advantages of low cost, applicability to various e-liquid systems and wide applicability to various electronic smoking devices.

[0036] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. Based on the description of the present invention, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

[0037] In the description of this invention, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0038] The terms “upper,” “lower,” “left,” “right,” “front,” “back,” “top,” “bottom,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use. They are only for the convenience of description and simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0039] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar attributes, not to indicate or imply relative importance or a specific order.

[0040] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0041] like Figures 1 to 3 As shown, the present invention provides a smoking device, which includes a mouthpiece 60, an oil storage chamber 12, an oil guide, an atomizing element 50, and a control switch 20. The oil storage chamber 12 is used to contain e-liquid 100, the oil guide guides the e-liquid 100 in the oil storage chamber 12 to the atomizing element 50 for atomization, and the control switch 20 is used to turn the atomizing element 50 on and off. The device also includes:

[0042] The atomizing channel 33 is connected to the mouthpiece 60, and the atomizing element 50 is located in the atomizing channel 33;

[0043] The first air intake channel 31 is connected to the atomizing channel 33, and the control switch 20 is located inside the first air intake channel 31;

[0044] The second air intake channel 32 is connected to the atomizing channel 33. The second air intake channel 32 has a conducting state and a closed state. When the second air intake channel 32 is in the closed state, the control switch 20 is opened and the atomizing element 50 is activated. When the second air intake channel 32 is in the conducting state, the control switch 20 is in the closed state and the atomizing element 50 is not activated.

[0045] Specifically, in this embodiment, the smoking device of the present invention includes a mouthpiece 60, an oil storage chamber 12, an oil guide, an atomizing element 50, and a control switch 20. The mouthpiece 60 is used to draw in the smoke generated by the atomization of heated e-liquid 100; the oil storage chamber 12 is used to hold the e-liquid 100; the oil guide guides the e-liquid 100 from the oil storage chamber 12 to the atomizing element 50 for atomization; and the control switch 20 is used to control the opening and closing of the atomizing element 50. Furthermore, refer to... Figure 1 The smoking device of the present invention may further include a battery 70 for energizing the atomizing element 50 and the control switch 20.

[0046] Meanwhile, the smoking device of the present invention also includes a first air intake channel 31, a second air intake channel 32, and an atomizing channel 33. The first air intake channel 31 is connected to the atomizing channel 33, and the control switch 20 is disposed therein; the second air intake channel 32 is connected to the atomizing channel 33, and has both open and closed states; the atomizing channel 33 is connected to the mouthpiece 60, and the atomizing element 50 is disposed therein. The first air intake channel 31 and the second air intake channel 32 serve as two air intake channels for the smoking device of the present invention, and can converge into the atomizing channel 33.

[0047] When the second air intake channel 32 is closed, the control switch 20 can be opened to activate the atomizer 50. The atomizer 50 heats and atomizes the e-liquid 100 guided from the oil storage chamber 12 to the atomizer 50 by the oil guide 121, so that the e-liquid 100 generates smoke in the atomization channel 33 for the user to inhale through the mouthpiece 60. When the second air intake channel 32 is open, the control switch 20 is closed and the atomizer 50 is not activated. The atomizer 50 stops heating and atomizing the e-liquid 100, and the e-cigarette stops working. Therefore, when the e-liquid 100 in the oil storage chamber 12 is sufficient, the second air intake channel 32 is kept closed, thereby opening the control switch 20 and activating the atomizing element 50, which in turn heats and atomizes the e-liquid to produce smoke for inhalation; when the e-liquid 100 in the oil storage chamber 12 is consumed to a low level or insufficient due to the operation of the e-cigarette, the second air intake channel 32 automatically becomes open, thereby switching the control switch 20 to the closed state and not activating the atomizing element 50, thus stopping the e-cigarette from working. This achieves the technical effect of automatically stopping the e-cigarette to prevent dry burning.

[0048] Therefore, the smoking device provided by the present invention can achieve the technical effect of preventing dry burning by setting a special air passage structure. This technical means has the advantages of low cost, applicability to various e-liquid systems and wide applicability to various electronic smoking devices.

[0049] In addition, the smoking device may also include an air inlet 311 and a smoke outlet 331. The air inlet 311 is located at the bottom of the smoking device, and the smoke outlet 331 is located at the top of the mouthpiece 60. When the smoking device is in operation, air enters the first air intake channel 31 through the air inlet 311, and then enters the atomization channel 33 from the first air intake channel 31. The smoke generated in the atomization chamber 13 in the atomization channel 33 is carried to the mouthpiece 60, and finally exits from the smoke outlet 331 at the top of the mouthpiece 60 to the outside of the smoking device, so that the smoke can be inhaled by a person.

[0050] As one implementation method, such as Figure 1As shown, the control switch 20 is an airflow sensor. When the second air intake channel 32 is closed and suction is applied from the nozzle 60, the control switch 20 is opened when the air pressure difference on both sides is not less than the trigger threshold. When the second air intake channel 32 is open and suction is applied from the nozzle 60, the control switch 20 is closed when the air pressure difference on both sides is less than the trigger threshold.

[0051] The airflow sensor can be a microphone, a MEMS gas sensor, etc. Specifically, in this embodiment, the control switch 20 is preferably a microphone. The microphone can respond to changes in airflow. When the airflow change meets its response conditions, the microphone can trigger the control circuit, thereby causing the atomizing element 50 to start working. Therefore, the microphone can control the opening and closing of the atomizing element 50. When the second air intake channel 32 is closed and suction is performed from the mouthpiece 60, the air outside the e-cigarette can only enter the first air intake channel 31 through the air intake hole 311, and then enter the atomizing channel 33 from the first air intake channel 31. Therefore, at this time, the control switch 20 located in the first air intake channel 31 experiences a large pressure difference between the upper and lower sides caused by the air flowing from top to bottom, which is sufficient to reach the trigger threshold of the control switch 20 and open the control switch 20. This allows the control switch 20 to activate the atomizing element 50 to heat and atomize the e-liquid 100 to produce smoke, and allows smoke to be inhaled through the mouthpiece 60. When the second air intake channel 32 is closed and air is drawn from the mouthpiece 60, air from outside the device can enter the first air intake channel 31 not only through the air intake hole 311 and then the atomization channel 33, but also through the second air intake channel 32. Therefore, the pressure difference between the upper and lower sides of the control switch 20 will be reduced to less than the trigger threshold of the control switch 20, causing the control switch 20 to change from open to closed and stop starting the atomizing component 50. The atomizing component 50 no longer heats and atomizes the e-liquid 100 to produce smoke, and no smoke can be drawn through the mouthpiece 60 at this time.

[0052] In one implementation, the second air intake channel 32 is connected to the atomizing channel 33 via the oil storage chamber 12. When the amount of e-liquid in the oil storage chamber 12 is lower than the first threshold, the second air intake channel 32 is in a connected state with the atomizing channel 33; while when the amount of e-liquid in the oil storage chamber 12 is greater than the second threshold, the second air intake channel 32 is in a closed state without being connected to the atomizing channel 33. The second threshold is greater than or equal to the first threshold.

[0053] Specifically, in this embodiment, by setting a first threshold and a second threshold, when the amount of e-liquid in the oil storage chamber 12 is lower than the first threshold, the second air intake channel 32 is in a connected state that is connected to the atomization channel 33, and when the amount of e-liquid in the oil storage chamber 12 is greater than the second threshold, the second air intake channel 32 is in a closed state that is not connected to the atomization channel 33, thereby enabling the second air intake channel 32 to switch between its connected state and closed state depending on the amount of e-liquid.

[0054] It should be noted that the "opening" of the second air intake channel 32 here means that the second air intake channel 32 can supply air during the suction state at the nozzle 60, and the air pressure difference across the control switch 20 is less than the trigger threshold. Similarly, the "closing" of the second air intake channel 32 means that the second air intake channel 32 is not supplying air or only supplies a small amount of air during the suction state at the nozzle 60, and the air pressure difference across the control switch 20 is not less than the trigger threshold.

[0055] It should also be noted that the first and second thresholds can be fixed values ​​or range values. When oil-retaining cotton is provided in the oil storage chamber 12, the first and second thresholds may vary within a small range due to the influence of the oil-retaining cotton material, its oil storage capacity, e-liquid concentration, air pressure, temperature, and other factors; that is, the first and second thresholds are range values. When oil-retaining cotton is not provided in the oil storage chamber 12, the e-liquid level / volume can be used as an indicator of the first and second thresholds; in this case, the first and second thresholds are fixed values. Based on the following description, those skilled in the art can adjust the position of the second through-hole according to actual conditions, thereby adjusting the first and second thresholds. As one implementation method, such as... Figure 1 As shown, the oil storage chamber 12 has a first through hole 1021 and a second through hole 1011. The first through hole 1021 is connected to the outside, and the second through hole 1011 is connected to the atomization channel 33. The first through hole 1021, the oil storage chamber 12 and the second through hole 1011 form a second air intake channel 32. A first liquid-proof and breathable membrane is provided at the first through hole, and a second liquid-proof and breathable membrane is provided at the second through hole 1011.

[0056] When the e-liquid in the oil storage chamber 12 is sealed by the first and / or second anti-liquid and breathable membranes, the second air intake channel 32 is in a closed state. When the first and second anti-liquid and breathable membranes in the liquid storage chamber are not sealed, the second air intake channel 32 is in a conductive state.

[0057] Specifically, in this embodiment, by providing a first through hole 1021 and a second through hole 1011 in the oil storage cavity 12, the first through hole 1021 connects the oil storage cavity 12 to the outside, and the second through hole 1011 connects the oil storage cavity 12 to the atomizing channel 33. The first through hole 1021, the oil storage cavity 12, and the second through hole 1011 are sequentially connected to form a second air intake channel 32. By providing a first liquid-proof and breathable membrane at the first through hole and a second liquid-proof and breathable membrane at the second through hole 1011, the e-liquid 100 in the oil storage cavity 12 can be prevented from flowing out from the first through hole 1021 and the second through hole 1011.

[0058] When the e-liquid in the oil reservoir 12 is sufficient, the e-liquid can seal the first and / or second liquid-proof and breathable membranes, preventing outside air from entering the oil reservoir 12 through the first through hole 1021. Therefore, the second air intake channel 32 is in a closed state at this time. When the e-liquid in the oil reservoir 12 is reduced to a small amount, the e-liquid can no longer seal the first and second liquid-proof and breathable membranes, and outside air can enter the oil reservoir 12 through the first through hole 1021 and then enter the atomization channel 33. Therefore, the second air intake channel 32 is in a conductive state at this time.

[0059] In other embodiments, the switching of the second air intake channel 32 between the open and closed states can also be achieved through the cooperation of a level gauge and a valve. In this case, the level gauge is used to measure the amount of e-liquid. When the amount of e-liquid decreases to a preset threshold, the valve opens, putting the second air intake channel 32 in the open state; conversely, the valve closes, putting the second air intake channel 32 in the closed state.

[0060] As one implementation method, such as Figure 1 As shown, the smoking device includes a carrier, in which an oil storage cavity 12 and an air passage 11 are formed. The air passage 11 connects to the outside and a first through hole 1021. The air passage 11, the first through hole 1021, the oil storage cavity 12 and the second through hole 1011 are sequentially connected to form a second air intake channel 32.

[0061] Specifically, in this embodiment, in addition to the first through hole 1021 and the second through hole 1011, an air passage 11 is also provided. In this case, the air passage 11, the first through hole 1021, the oil storage chamber 12, and the second through hole 1011 are sequentially connected to form a second air intake channel 32. By setting the air passage 11, outside air first enters the air passage 11 and then enters the oil storage chamber 12 through the first through hole 1021, which is beneficial for the air intake of the second air intake channel 32.

[0062] In this embodiment, the carrier can be a tobacco cartridge, which is detachably connected to the main body of the smoking device. In other embodiments, the carrier can also be a non-detachable part of the smoking device.

[0063] As one implementation method, such as Figure 1 As shown, the airway 11 extends vertically and has a third through hole 1031 that connects to the outside. The third through hole 1031 is higher than the first through hole 1021.

[0064] Specifically, in this embodiment, by setting the air passage 11 to extend vertically and having a third through hole 1031 that can connect to the outside, and setting the third through hole 1031 higher than the first through hole 1021, it is beneficial to use gravity to prevent the e-liquid 100 in the oil storage chamber 12 from leaking through the air passage 11.

[0065] As one implementation method, such as Figure 1 As shown, the third through hole 1031 is provided with a third liquid-proof and breathable membrane.

[0066] Specifically, in this embodiment, by providing a third liquid-proof and breathable membrane at the third through hole 1031, the third liquid-proof and breathable membrane can further prevent the e-liquid 100 in the oil storage cavity 12 from leaking to the outside through the third through hole 1031.

[0067] In one embodiment, the oil storage cavity 12 is provided with oil storage cotton for storing e-liquid 100. The oil storage cavity 12 is provided with an oil guide hole. The oil guide extends into the oil guide hole and guides the e-liquid 100 in the oil storage cavity 12 to the atomizing component 50 for atomization. The oil guide hole is higher than the second through hole 1011.

[0068] Specifically, an oil storage cotton is installed in the oil storage cavity 12 to store e-liquid 100. Then, an oil guide hole is opened in the oil storage cavity 12 so that the oil guide component extends into the oil guide hole and guides the e-liquid 100 in the oil storage cavity 12 to the atomizing component 50 for atomization.

[0069] With the oil-retaining cotton in place, oil guiding via the oil guide and the oil guide hole is convenient, and the location of the oil guide hole is not very limited. Therefore, the location of the second through hole 1011 can be given priority. It is understood that the lower the height of the second through hole 1011, the less e-liquid 100 remains in the oil-retaining cavity 12 when the control switch 20 cannot be triggered. Preferably, the second through hole 1011 is located on the side of the oil-retaining cavity 12 near the bottom, or at the bottom of the oil-retaining cavity 12 and extending to the wall of the atomizing cavity 13. In this case, the oil guide hole is located above the second through hole 1011. Through the capillary action of the oil guide and oil-retaining cotton, the e-liquid 100 can be guided from below the height of the oil guide hole to the atomizing component 50.

[0070] Therefore, by setting the oil guide hole higher than the second through hole 1011, it is beneficial to minimize the amount of e-liquid 100 while ensuring the anti-dry burning effect, so as to enhance the anti-dry burning effect of the smoking device.

[0071] In other embodiments, the oil storage chamber 12 does not contain oil-retaining cotton; it only stores e-liquid. An oil guide hole is provided, and an oil guide extends into the oil guide hole to guide the e-liquid 100 in the oil storage chamber 12 to the atomizing component 50 for atomization. Since there is no oil-retaining cotton in the oil storage chamber 12, the effectiveness of guiding the e-liquid in the oil storage chamber 12 to the atomizing component 50 must be prioritized. Therefore, the oil guide hole needs to be located as far as possible at the lower end of the oil storage chamber 12 to better utilize gravity and enhance the oil guiding effect. In this case, the second through hole 1011 is preferably positioned higher than the oil guide hole.

[0072] In one embodiment, the oil storage cavity 12 is provided with an oil guide hole, and the oil guide member extends into the oil guide hole to guide the e-liquid 100 in the oil storage cavity 12 to the atomizing member 50 for atomization. The second through hole 1011 is higher than the oil guide hole.

[0073] Specifically, by providing an oil guide hole in the oil storage chamber 12, the oil guide component can guide the e-liquid 100 in the oil storage chamber 12 to the atomizing component 50 for atomization.

[0074] The oil guide hole and the second through hole 1011 are spaced apart. Further, as an embodiment, the second through hole 1011 is preferably located below the oil guide hole. By positioning the second through hole 1011 below the oil guide hole, when the e-liquid 100 level in the oil storage chamber 12 is below a set threshold (i.e., below the second through hole 1011), because the oil guide hole is only located above the second through hole 1011, the e-liquid 100 in the oil storage chamber 12 is not connected to the oil guide hole. Therefore, the oil guide component cannot guide the e-liquid 100 in the oil storage chamber 12 to the atomizing component 50 for atomization through the oil guide hole.

[0075] Therefore, the second through hole 1011 is located below the oil guide hole, which can prevent the oil guide component from guiding the e-liquid 100 in the oil storage chamber 12 to the atomizing component 50 for atomization when the e-liquid is low or completely consumed, thereby enhancing the anti-dry burning effect of the smoking device of the present invention.

[0076] As one implementation method, such as Figure 1 As shown, the carrier also has an atomizing chamber 13 extending vertically, an oil storage chamber 12 is arranged around the atomizing chamber 13, an air passage 11 is located outside the oil storage chamber 12, the atomizing chamber 13 and the nozzle 60 are connected to form an atomizing channel 33, and the atomizing element 50 is inside the atomizing chamber 13.

[0077] Specifically, the carrier is provided with an atomizing chamber 13 extending vertically. An oil storage chamber 12 is arranged around the periphery of the atomizing chamber 13, and an air passage 11 is located outside the oil storage chamber 12. The atomizing chamber 13 and the mouthpiece 60 are connected to form an atomizing channel 33. The atomizing element 50 is disposed within the atomizing chamber 13. The atomizing element 50 heats the e-liquid 100 guided from the oil storage chamber 12 to the atomizing chamber 13. After the e-liquid 100 is heated and atomized into vapor within the atomizing chamber 13, the vapor can be drawn out of the atomizing chamber 13 through the mouthpiece 60. Therefore, the channel connecting the atomizing chamber 13 and the mouthpiece 60 serves as the atomizing channel 33. In other implementation examples, the arrangement of the air passage 11, the oil storage chamber 12, and the atomizing chamber 13 can also be such that the oil storage chamber 12 is located above the atomizing chamber 13, so that the oil storage chamber 12 can supply oil to the atomizing chamber 13. The air passage 11 and the oil storage chamber 12 can also be arranged vertically to achieve technical effects such as using gravity to facilitate air intake and prevent oil leakage.

[0078] As one implementation method, such as Figure 1 As shown, the carrier includes a first cylindrical section 101, a second cylindrical section 102, and a third cylindrical section 103 arranged from the inside to the outside. The first cylindrical section 101 encloses an atomizing chamber 13. The second cylindrical section 102 and the first cylindrical section 101 enclose an oil storage chamber 12. The third cylindrical section 103 and the second cylindrical section 102 enclose an air passage 11. A third through hole 1031 is opened in the third cylindrical section 103. The second cylindrical section 102 has a first through hole 1021, and the first cylindrical section 101 has a second through hole 1011.

[0079] Specifically, the carrier structure is a three-layer nested structure consisting of an atomizing chamber 13, an oil storage chamber 12, and an air passage 11, from the inside out. When the second air intake passage 32 is open, outside air enters the air passage 11 through the third through hole 1031, then enters the oil storage chamber 12 through the first through hole 1021, and then enters the atomizing chamber 13 through the second through hole 1011, i.e., the atomizing passage 33, and finally exits the outside of the smoking device from the mouthpiece 60 along the atomizing passage 33.

[0080] In addition, such as Figure 1 As shown, the smoking device includes a sealing element 40, which is located above and below the air passage 11 and the oil storage chamber 12, respectively, and can effectively seal the air passage 11 and the oil storage chamber 12 to prevent leakage. The sealing element 40 can be made of silicone sealant.

[0081] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0082] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
