Description

Technical Field

[0001] This invention relates to the field of atomization technology, and in particular to an electronic cigarette. Background Technology

[0002] Atomization technology, which transforms liquids into aerosol media in the form of smoke through heating, pressurization, or sound waves, is widely used in fields such as medical treatment, bituminous coal atomization, and e-cigarettes.

[0003] Electronic cigarettes, also known as virtual cigarettes, electronic atomizers, or vaporizers, have the same appearance and taste as cigarettes. They are mainly used to simulate the feeling of smoking without affecting health, for the purpose of quitting smoking or replacing cigarettes.

[0004] Electronic cigarettes typically consist of a mouthpiece, a liquid reservoir, an atomizing assembly, and a battery. The liquid reservoir stores the atomizable liquid; the atomizing assembly usually includes a heating element and a liquid guide. The heating element is positioned on the liquid guide, which contacts the liquid reservoir, absorbing the atomizable liquid and transferring it to the heating element for heating and atomization into inhalable vapor; the battery provides the energy needed to heat the heating element. When the user inhales through the mouthpiece, outside air enters the atomizing assembly and, along with the atomized vapor, enters the user's mouth through the mouthpiece for inhalation.

[0005] Most of the vapor produced by atomization is inhaled into the user's mouth, with a small portion remaining in the mouthpiece channel. On one hand, this residual vapor condenses in the mouthpiece channel, forming condensate that adheres to the mouthpiece. When a significant amount of condensate accumulates, the user may inhale it along with the vapor when inhaling again, negatively impacting the user experience. On the other hand, the vapor remaining inside the device can also condense and adhere to electronic components, potentially damaging them. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide an electronic cigarette that drives the smoke remaining in the mouthpiece channel out of the mouthpiece channel, preventing the smoke from condensing in the mouthpiece channel and generating condensate, thus solving the problem in the prior art that the smoke remaining in the mouthpiece is easily condensed into atomized liquid in the mouthpiece channel, affecting the user's vaping experience and the lifespan of the electronic cigarette.

[0007] This invention provides an electronic cigarette, comprising:

[0008] Liquid storage assembly, the liquid storage assembly being used to store atomizing liquid;

[0009] An atomizing component is provided with an atomizing channel, a liquid storage component is connected to the atomizing component, and the atomizing liquid can be heated within the atomizing channel;

[0010] The nozzle is provided with a nozzle channel that communicates with the atomizing channel;

[0011] A fan assembly is provided with an air intake channel between the fan assembly and the atomizing assembly. The air intake channel is connected to the atomizing channel. The fan assembly includes multiple fan blades and a rotating body for driving the fan blades to rotate. The fan blades can rotate around the axis of the rotating body and generate airflow that flows sequentially along the air intake channel, the atomizing channel and the mouthpiece channel.

[0012] In the electronic cigarette of this embodiment, the rotating body drives the fan blades to rotate, generating airflow that flows sequentially along the air intake channel, atomization channel and mouthpiece channel. This forces the smoke remaining in the mouthpiece channel out of the mouthpiece channel, preventing the smoke from condensing and producing condensate in the mouthpiece channel, thus improving the user's vaping experience and the lifespan of the electronic cigarette.

[0041] First Embodiment

[0042] like Figure 1-13 As shown, this embodiment provides an electronic cigarette, including a liquid storage component 20, an atomizing component 30, a mouthpiece 10, and a fan component 60.

[0043] like Figure 1-3As shown, in this embodiment, the liquid storage component 20 is used to store the atomizing liquid; the atomizing component 30 is provided with an atomizing channel 33, the liquid storage component 20 is connected to the atomizing component 30, and the atomizing liquid can be heated into smoke in the atomizing channel 33; the mouthpiece 10 is provided with a mouthpiece channel 13, which is connected to the atomizing channel 33; an air intake channel 52 is provided between the fan component 60 and the atomizing component 30, which is connected to the atomizing channel 33. The fan component 60 includes multiple fan blades 62 and a rotating body 61 for driving the fan blades 62 to rotate. The fan blades 62 can rotate around the axis of the rotating body 61 and generate airflow that flows sequentially along the air intake channel 52, the atomizing channel 33 and the mouthpiece channel 13.

[0044] In the electronic cigarette of this embodiment, the rotating body 61 drives the fan blade 62 to rotate, generating an airflow that flows sequentially along the air intake channel 52, the atomization channel 33 and the mouthpiece channel 13, driving the smoke remaining in the mouthpiece channel 13 out of the mouthpiece channel 13, preventing the smoke from condensing in the mouthpiece channel 13 and generating condensate, thereby improving the user's vaping experience and the lifespan of the electronic cigarette.

[0045] like Figure 2 and Figure 3 As shown, in one embodiment, the fan blade 62 is connected to the upper surface of the rotating body 61. The rotating body 61 is provided with a ventilation channel 63 that runs through the upper and lower surfaces of the rotating body 61. Air located below the rotating body 61 can pass through the ventilation channel 63 and enter the air intake channel 52.

[0046] The rotating body 61 is disc-shaped, and the fan blades 62 are inclined upwards and fixedly connected to the upper surface of the rotating body 61. All fan blades 62 have the same inclination angle to the upper surface of the rotating body 61 along the same counterclockwise or clockwise direction. The fan blades 62 can be fixedly connected to the rotating body 61 by snap-fitting, gluing, or integral molding. Driven by the rotating body 61, the fan blades 62 can push the air in the air intake channel 52 and generate an upward airflow. In some embodiments, the inclination angle of the fan blades 62 can be adjusted according to factors such as air volume and airflow force.

[0047] In one embodiment, each fan blade 62 is equipped with a ventilation channel 63, which is located between two adjacent fan blades 62. In this embodiment, there are six fan blades 62 and six ventilation channels 63. Each fan blade 62 is equipped with a ventilation channel 63, which is located between two connected fan blades 62. When the rotating body 61 rotates, the fan blades 62 generate an upward airflow in the air intake channel 52, thus creating a pressure difference between the upper and lower surfaces of the rotating body 61. This allows air located below the rotating body 61 to pass through the ventilation channel 63 and enter the air intake channel 52. In other embodiments, the number of fan blades 62 and the number and position of ventilation channels 63 can be adjusted as needed. For example, there are six fan blades 62 and twelve ventilation channels 63, with six ventilation channels 63 located between two adjacent fan blades 62 and the other six ventilation channels 63 located directly below each fan blade 62.

[0048] like Figure 1 As shown, in one embodiment, the fan assembly 60 has an upper cylinder 50 and a lower cylinder 80 connected to its upper and lower ends, respectively. The upper cylinder 50 houses the battery assembly 40, and the air intake channel 52 is formed by the enclosure between the inner wall of the upper cylinder 50 and the outer wall of the battery assembly 40. The lower cylinder 80 has a receiving cavity (not described), and an air intake hole 82 communicating with the receiving cavity is opened on the shell wall of the lower cylinder 80. The upper cylinder 50 is a hollow cylindrical tube, and the lower cylinder 80 is a cylindrical container. Outside cold air can pass through the air intake hole 82, the receiving cavity, and the ventilation channel 63 in sequence and enter the air intake channel 52.

[0049] In this embodiment, the battery assembly 40 is cylindrical, and its axis coincides with the axis of the fan assembly 60. Multiple fan blades 62 are evenly distributed around the battery assembly 40. The inner contours of the fan blades 62 enclose a circular battery assembly mounting position 65. The size of the mounting position 65 matches the outer contour of the battery assembly 40, facilitating the positioning and assembly of the battery assembly 40. This positions the fan blades 62 between the battery assembly 40 and the upper cylinder 50, effectively reducing the installation space and making the electronic cigarette structure more compact.

[0050] In this embodiment, the fan assembly 60 is exposed and its outer wall can be manually driven to rotate the fan assembly 60 around the axis of the rotating body 61.

[0051] like Figure 1 and Figure 4As shown, in one embodiment, the upper and lower ends of the rotating body 61 are respectively provided with a first annular groove 67a and a second annular groove 68a. The upper cylinder 50 is provided with a first annular locking body 51a that engages with the first annular groove 67a, and the first annular locking body 51a can rotate along the first annular groove 67a. The lower cylinder 80 is provided with a second annular locking body 81a that engages with the second annular groove 68a, and the second annular locking body 81a can rotate along the second annular groove 68a. The first annular locking body 51a and the second annular locking body 81a are used to limit the rotation of the rotating body 61, ensuring that the rotating body 61 can only rotate along its axis under external force. After the electronic cigarette is used up, the rotating body 61 can be manually rotated to rotate the fan blades 62 and create an upward airflow, driving the residual smoke out of the mouthpiece channel 13 and preventing condensation of the smoke in the mouthpiece channel 13.

[0052] like Figure 1 and Figure 5 As shown, in another embodiment, the upper and lower ends of the rotating body 61 are respectively provided with a third annular retaining body 67b and a fourth annular retaining body 68b. The upper cylinder 50 is provided with a third annular retaining groove 51b that engages with the third annular retaining body 67b, allowing the third annular retaining body 67b to rotate along the third annular retaining groove 51b. The lower cylinder 80 is provided with a fourth annular retaining groove 81b that engages with the fourth annular retaining body 68b, allowing the fourth annular retaining body 68b to rotate along the fourth annular retaining groove 81b. The third annular retaining groove 51b and the fourth annular retaining groove 81b are used to limit the rotation of the rotating body 61, ensuring that under external force, the rotating body 61 can only rotate along its axis.

[0053] like Figure 1 and Figure 6 As shown, the mouthpiece 10 of this embodiment includes a mouthpiece portion 11 and a housing portion 12 connected to the mouthpiece portion 11. The housing portion 12 covers the upper cylinder 50 and serves as the housing of the electronic cigarette. The mouthpiece portion 11 is trumpet-shaped, and its diameter decreases from one end connected to the housing portion 12 to the other end. The outer wall of the mouthpiece portion 11 is arc-shaped, and its outer contour conforms to the ergonomic structure, which can fit the mouth of the human body, making it convenient for the user to hold the mouthpiece portion 11 in their mouth and inhale the smoke in the mouthpiece channel 13.

[0054] like Figure 1 and Figure 7 As shown, in one embodiment, the liquid storage assembly 20 includes an oil storage cotton 21, which has a smoke channel 24 penetrating the upper and lower surfaces of the oil storage cotton. The smoke channel 24 is connected to the mouthpiece channel 13. The atomizing assembly 30 includes an atomizing core 31, which is located inside the smoke channel 24. The fan assembly is capable of generating an airflow that flows sequentially along the air intake channel 52, the smoke channel 24, the atomizing channel 33, and the mouthpiece channel 13.

[0055] The oil-retaining cotton 21 is made of cotton materials such as fiber cotton, degreased cotton, and organic cotton, and has many fluffy pores, which can absorb a sufficient amount of atomizing liquid, providing ample atomizing liquid for the atomizing core 31. The atomizing core 31 is equipped with an oil-guiding cotton 314 and a heating net 313. The oil-guiding cotton 314 is cylindrical and forms an atomization channel 33. The heating net 313 is installed in the atomization channel 33. An oil-guiding hole 34 is provided between the oil-guiding cotton 314 and the oil-retaining cotton 21. The atomizing liquid in the oil-retaining cotton 21 can penetrate through the oil-guiding hole 34 to the oil-guiding cotton 314 and reach the heating net 313. The heating net 313 is connected to two electrodes (not labeled), both of which are electrically connected to the battery assembly 40. The heating net 313 is made of metal materials such as iron-chromium-aluminum, stainless steel, nickel-chromium alloy, pure nickel, and pure titanium. When connected to electricity, it can heat the atomizing liquid and atomize it into smoke.

[0056] like Figure 7 and Figure 9 As shown, the atomizing assembly 30 also includes an oil-guiding cotton cover 32, which abuts against the lower surface of the oil-retaining cotton 21. The oil-guiding cotton cover 32 has a cotton cover channel 320 that communicates with the smoke channel 24 and the air intake channel 52. The lower surface of the oil-guiding cotton cover 32 is recessed upward to form an air-guiding groove 321, and the upper surface of the oil-guiding cotton cover 32 extends upward to form a connecting boss (not noted). The connecting boss has an air-guiding hole 322 that penetrates the upper and lower surfaces of the oil-guiding cotton cover 32. The air-guiding hole 322 is connected to the air-guiding groove 321 to form the cotton cover channel 320. The air-guiding groove 321 can be a cross groove, a straight groove, or other shapes of groove, which can be adjusted according to requirements. The oil-guiding cotton cover 32 also has an electrode connection hole (not noted) for two electrodes to pass through. The electrode connection hole penetrates the upper and lower surfaces of the oil-guiding cotton cover 32, which facilitates the direct connection of the two electrodes to the battery assembly 40.

[0057] like Figure 7 and Figure 8As shown, in this embodiment, the atomizing assembly 30 further includes an oil-guiding cotton shell 311 that abuts against the inner wall of the smoke channel 24. The oil-guiding cotton shell 311 is used to prevent the atomizing liquid in the oil-retaining cotton 21 from directly penetrating into the smoke channel 24. The liquid storage assembly 20 also includes an oil-retaining cap 22 for preventing the atomizing liquid in the oil-retaining cotton 21 from leaking out. The oil-retaining cap 22 is connected to the top of the oil-retaining cotton 21, and a connecting channel (not annotated) is provided in the middle of the cap, penetrating the upper and lower surfaces of the oil-retaining cotton 21. The connecting channel is used to connect the smoke channel 24 and the mouthpiece channel 13. The lower end of the oil-retaining cap 22 is provided with a connecting pipe 221 that extends into the smoke channel. The connecting pipe 221 abuts against the inner wall of the smoke channel 24, and the connecting pipe 221 partially overlaps with the oil-guiding cotton shell 311. The non-overlapping part forms an oil-guiding hole 34 through which the atomizing liquid can pass. The upper surface of the oil reservoir cap 22 is recessed downwards to form a condenser cotton mounting position (not described). The condenser cotton mounting position is used to install condenser cotton 23. The condenser cotton 23 can absorb the condensate that condenses and drips in the suction channel 13, preventing the condensate from being sucked into the user's mouth. In this embodiment, the oil reservoir cotton 21 has multiple layers, and an atomizing tube 312 is embedded between the multiple layers of oil reservoir cotton 21. The end of the atomizing tube 312 is embedded in the connecting tube 221, which facilitates the installation and fixation of the oil guiding cotton 314 and the heating mesh 313.

[0058] like Figure 1 , Figure 10-12 As shown, in one embodiment, the electronic cigarette further includes a threaded rotating post 70, a microphone compartment 92, and a microphone 91. The microphone compartment 92 has a microphone cavity 94, and the microphone 91 is located inside the microphone cavity 94. The upper end of the threaded rotating post 70 is threadedly connected to the fan assembly 60, and the lower end of the threaded rotating post 70 is connected to the microphone compartment 92. A connecting air passage (not noted) for connecting the microphone cavity 94 and the air intake passage 52 is formed between the microphone compartment 92 and the threaded rotating post 70.

[0059] Driven by the fan assembly 60, the threaded rotating column 70 can move up and down reciprocally, allowing the electronic cigarette to switch between a locked and unlocked state: in the unlocked state, the microphone cavity 94 is connected to the air intake channel 52 through the connecting air passage; in the locked state, the microphone cavity 94 is not connected to the air intake channel 52. In this embodiment, a connecting air hole 95 is provided on the bottom wall of the microphone compartment 92. The microphone 91 is located directly above the connecting air hole 95 and covers the connecting air hole 95, cutting off the airflow passage between the connecting air hole 95 and the microphone cavity 94. The lower surface of the microphone compartment 92 abuts against the upper surface of the bottom wall of the lower cylinder 80, making the connecting air hole 95 a sealed cavity. In some embodiments, the position of the connecting air hole 95 can be adjusted as needed; for example, the connecting air hole 95 is located on the side wall of the microphone compartment 92.

[0060] The microphone 91 is used to detect the pressure difference between the microphone cavity 94 and the connecting air port 95 to control the start or stop of the atomizing component 30. In the locked state, the air intake channel is not connected to the microphone cavity 94, and the pressure difference between the microphone cavity 94 and the connecting air port 95 is within a preset pressure difference range, so the atomizing core 31 is in the stopped state. In the unlocked state, the air intake channel 52 is connected to the microphone cavity 94, and when the pressure difference between the microphone cavity 94 and the connecting air port 95 exceeds the preset pressure difference range, the atomizing core 31 is in the started state. By switching between the locked and unlocked states, the electronic cigarette can have a child lock function to prevent the electronic cigarette from being accidentally started by a child and to prevent children from imitating adults to smoke electronic cigarettes.

[0061] In one embodiment, when the fan assembly 60 rotates to generate an upward airflow, the fan assembly 60 can drive the threaded rotating column 70 to move downward. After vaping, the fan assembly 60 can be rotated to generate an upward airflow in the air intake channel 52, clearing away any remaining smoke in the mouthpiece channel 13. Simultaneously, the threaded rotating column 70 moves downward, gradually obscuring the connecting airway by the microphone compartment 92, thus locking the e-cigarette and implementing a child lock function. After vaping, a single unidirectional rotation allows the e-cigarette to simultaneously perform smoke removal and child lock functions, providing convenient operation and improving the user experience.

[0062] In another embodiment, the fan assembly 60 generates an upward airflow regardless of whether it rotates clockwise or counterclockwise. When the fan assembly 60 rotates clockwise, the threaded rotating column 70 moves downward; when the fan assembly 60 rotates counterclockwise, the threaded rotating column 70 moves upward. This reciprocating clockwise and counterclockwise rotation drives the fan assembly 60 to rotate, causing the threaded rotating column 70 to move back and forth. This, in turn, drives the fan assembly 60 to continuously generate an upward airflow within the air intake channel 52, effectively removing any remaining smoke from the nozzle channel 13.

[0063] like Figure 10-13 As shown, the microphone compartment 92 is also provided with a microphone connection hole 93 that communicates with the microphone cavity 94. The microphone connection hole 93 is connected to the lower end of the threaded rotating column 70. In the unlocked state, the microphone cavity 94 is connected to the air intake channel 52 through the microphone connection hole 93 and the connecting air passage; in the locked state, the microphone connection hole 93 and the connecting air passage are separated by the threaded rotating column 70, or the connecting air passage and the air intake channel 52 are separated by the microphone compartment 92, so that the microphone cavity 94 is not connected to the air intake channel 52.

[0064] like Figure 11 and Figure 12As shown, in this embodiment, the entire outer circumferential surface of the threaded rotating column 70 is provided with external threads 75, and the hole wall of the microphone connection hole 93 is provided with a first internal thread (not shown) adapted to the external threads 75, so that the lower end of the threaded rotating column 70 is threadedly connected to the microphone connection hole 93. A fan connection hole 64 is provided in the axial direction of the fan assembly 60, and the hole wall of the fan connection hole 64 is provided with a second internal thread (not shown) adapted to the external threads 75, and the first internal thread and the second internal thread have the same direction of rotation. The threaded rotating column 70, the fan connection hole 64, and the microphone connection hole 93 all have the same thread direction and pitch. When the fan assembly 60 drives the threaded rotating column 70 to move downward, the distance the threaded rotating column 70 moves out of the fan connection hole 64 is equal to the distance the threaded rotating column 70 moves into the microphone connection hole 93. Similarly, when the fan assembly 60 drives the threaded rotating column 70 to move upward, the distance the threaded rotating column 70 moves out of the microphone connection hole 93 is equal to the distance the threaded rotating column 70 moves into the fan connection hole 64.

[0065] In another embodiment, the external thread 75 includes an upper external thread (not shown) and a lower external thread (not shown) connected together. The upper and lower external threads have the same direction of rotation, but the pitches of the upper and lower external threads are different. The upper external thread is only threadedly connected to the second internal thread of the fan connection hole 64, and the lower external thread is only threadedly connected to the first internal thread of the microphone connection hole 93. The total length of the upper external thread is greater than or equal to the depth of the fan connection hole 64, and the total length of the lower external thread is greater than or equal to the depth of the microphone connection hole 93. This can prevent the threaded rotating column 70 from getting stuck and unable to rotate during rotation.

[0066] like Figure 10-13 As shown, in one embodiment, one end of the connecting air passage is connected to the lower surface of the threaded rotating column 70 and communicates with the microphone connection hole 93, while the other end of the connecting air passage is formed on the outer peripheral surface of the threaded rotating column 70. In the locked state, the connecting air passage is covered by the hole wall of the microphone connection hole 93, and the connecting air passage and the air intake channel 52 are separated by the microphone compartment 92; in the unlocked state, the connecting air passage is at least partially exposed and communicates with the air intake channel 52.

[0067] like Figure 10-12 As shown, in this embodiment, the threaded rotating column 70 is a hollow structure with an internal air guide cavity 73. The upper end of the threaded rotating column 70 is closed and the lower end is open. The side wall of the threaded rotating column 70 is provided with an air guide hole 72 that communicates with the air guide cavity 73. The connecting channel consists of the air guide cavity 73 and the air guide hole 72. In the locked state, the air guide hole 72 is blocked by the hole wall of the microphone connection hole 93, and the air guide hole 72 is not connected to the air intake channel 52; in the unlocked state, the air guide hole 72 is exposed and connected to the air intake channel 52.

[0068] The threaded rotating column 70 is a hollow cylindrical structure with a closed upper end and an open lower end forming an air guide chamber 73 that communicates with the microphone cavity 94. When the electronic cigarette is not in use, the fan assembly 60 can be rotated to move the threaded rotating column 70 downwards, thereby blocking the air guide hole 72 from the wall of the microphone connection hole 93, putting the electronic cigarette into a locked state, cutting off the airflow path between the air intake channel 52 and the microphone cavity 94, and maintaining a constant air pressure in the microphone cavity 94, thus driving the electronic cigarette into a locked state. This also clears residual smoke in the mouthpiece channel 13 and enables a child lock function.

[0069] like Figure 13 As shown, in one embodiment, an elastic film 71 is provided in the air guide cavity 73. The distance between the elastic film 71 and the lower end of the threaded rotating column 70 is greater than the distance between the air guide hole 72 and the lower end of the threaded rotating column 70, and the distance between the elastic film 71 and the lower end of the threaded rotating column 70 is less than the distance between the bottom surface of the air guide cavity 73 and the lower end of the threaded rotating column 70.

[0070] When the air vent 72 is blocked by the wall of the microphone connection hole 93, if the threaded rotating column 70 continues to rotate downwards, air in the microphone cavity 94 cannot be discharged, causing the pressure in the microphone cavity 94 to increase. This causes the pressure difference between the two ends of the microphone 91 to exceed the pressure difference threshold range, thus keeping the atomizing core 31 in the activated state. By setting an elastic film 71 in the air vent cavity 73, when the air vent 72 is blocked, the elastic film 71 can elastically deform upwards, increasing the volume of the air vent cavity 73, preventing the pressure in the microphone cavity 94 from increasing, and preventing the pressure difference between the two ends of the microphone 91 from exceeding the pressure difference threshold range, so that the atomizing core 31 remains in the stopped state.

[0071] In another embodiment, the threaded rotating post 70 is clearance-fitted with the microphone connection hole 93. This creates a small gap between the threaded rotating post 70 and the microphone connection hole 93, allowing air in the microphone cavity 94 to escape through this gap as the threaded rotating post 70 moves downward, maintaining the pressure in the microphone cavity 94 within the normal threshold range and preventing the pressure difference between the two ends of the microphone 91 from exceeding the threshold range.

[0072] Second Embodiment

[0073] The structure of the electronic cigarette in this embodiment is basically the same as that of the electronic cigarette in the first embodiment, except that:

[0074] like Figure 1 , Figure 14 and Figure 15As shown, in this embodiment, the fan assembly 60 includes a rotating body 61 and fan blades 62. The rotating body 61 is provided with an annular receiving groove 66 that runs through the upper and lower surfaces of the rotating body. The fan blades 62 are located in the receiving groove 66. An air passage 63 is formed between two adjacent fan blades 62. Air located below the rotating body 61 can pass through the air passage 63 and enter the air intake passage 52.

[0075] The rotating body 61 includes two concentric annular bodies of different sizes. A receiving groove 66 is provided between the larger and smaller annular bodies. Fan blades 62 are embedded in the receiving groove 66 and fixedly connected to the groove wall. The fan blades 62 can be fixedly connected to the groove wall of the receiving groove 66 by snap-fit, adhesive bonding, or integral molding. In this embodiment, there are six fan blades 62, all of which have an upward curvature. Driven by the rotating body 61, the fan blades 62 can push the air in the intake channel 52 and generate an upward airflow. In other embodiments, the number of fan blades 62 can be adjusted according to requirements; for example, there can be four, eight, ten, or twelve fan blades.

[0076] like Figure 15 As shown, in this embodiment, the upper surface of the rotating body 61 is provided with a circular battery assembly mounting position 65. The size of the battery assembly mounting position 65 matches the outer contour of the battery assembly 40, which facilitates the positioning of the battery assembly 40 and the assembly of the electronic cigarette. This allows the fan blade 62 to be located between the battery assembly 40 and the upper cylinder 50, effectively reducing the installation space and making the structure of the electronic cigarette more compact.

[0077] Third Embodiment

[0078] The structure of the electronic cigarette in this embodiment is basically the same as that of the electronic cigarette in the first embodiment, except that:

[0079] like Figure 16-18 As shown, in this embodiment, the outer circumferential surface of the threaded rotating column 70 is recessed to form an air guide groove 74. The air guide groove 74 is connected to the lower surface of the threaded rotating column 70 but not to the upper surface of the threaded rotating column 70, and the air guide groove 74 is connected to the microphone cavity 94. In the locked state, the entire air guide groove 74 is covered by the hole wall of the microphone connection hole 93, and the air guide groove 74 is not connected to the air intake channel 52; in the unlocked state, the air guide groove 74 is at least partially exposed and connected to the air intake channel 52.

[0080] Among them, such as Figure 17As shown, the threaded rotating column 70 has a columnar structure with threaded grooves on its outer side wall. An air guide groove 74 is located on the outer side wall near the lower surface of the threaded rotating column 70, passing through the lower surface of the threaded rotating column 70 and communicating with the microphone connection hole 93. When the electronic cigarette is not in use, the fan assembly 60 can be rotated to move the threaded rotating column 70 downwards, thereby blocking the entire air guide groove 74 from the wall of the microphone connection hole 93, locking the electronic cigarette and cutting off the airflow path between the air intake channel 52 and the microphone cavity 94, keeping the air pressure inside the microphone cavity 94 constant. This not only removes residual smoke from the mouthpiece channel 13 but also enables a child lock function to prevent children from imitating adults using electronic cigarettes.

[0081] In another embodiment, such as Figure 18 As shown, the air guide groove 74 can penetrate the side wall of the threaded rotating column, so that the air guide groove 74 has a straight or cross-shaped structure.

[0082] Fourth embodiment

[0083] The structure of the electronic cigarette in this embodiment is basically the same as that of the electronic cigarette in the first embodiment, except that:

[0084] like Figure 19-21 As shown, in one embodiment, the external thread 75 is provided on the outer peripheral surface of the upper end of the threaded rotating column 70. Between the outer peripheral surface of the lower end of the threaded rotating column 70 and the hole wall of the microphone connecting hole 93, one of the two is provided with an axially extending limiting rib 76, and the other of the two is provided with an axially extending limiting groove 931. The limiting groove 931 is adapted to the limiting rib 76.

[0085] In this embodiment, the fan assembly 60 is threadedly connected to the external thread 75 at the upper end of the threaded rotating column 70. Two limiting ribs 76 are symmetrically provided on the outer circumference of the lower end of the threaded rotating column 70. Two limiting grooves 931 are fitted into the wall of the microphone connection hole 93, which restrict the rotation of the threaded rotating column 70. When the fan assembly 60 rotates, it tends to drive the threaded rotating column 70 to rotate. Due to the interaction between the limiting grooves 931 and the limiting ribs 76, the threaded rotating column 70 cannot rotate, allowing it to move only up and down along the limiting grooves 931.

[0086] Driven by the fan assembly 60, the threaded rotating column 70 can reciprocate up and down along the axial direction of the fan connection hole 64, allowing the electronic cigarette to switch between a locked and unlocked state: in the unlocked state, the connecting airway is exposed in the microphone chamber 92, and the microphone chamber 94 is connected to the air intake channel 52 through the connecting airway; in the locked state, the connecting airway extends into the microphone chamber 92, and the connecting airway is covered by the microphone chamber 92. By switching between the locked and unlocked states, the electronic cigarette can have a child lock function, preventing the electronic cigarette from being accidentally started by a child and preventing children from imitating adults to smoke electronic cigarettes.

[0087] In another embodiment, the fan assembly 60 is threaded to the external thread 75 at the upper end of the threaded rotating column 70. The outer circumferential surface of the lower end of the threaded rotating column 70 is symmetrically provided with two limiting grooves (not shown). Two limiting ribs (not shown) are adapted to the hole wall of the microphone connection hole 93. The limiting ribs can restrict the rotation of the threaded rotating column 70, so that the threaded rotating column 70 can only move up and down along the limiting ribs.

[0088] Fifth Embodiment

[0089] The structure of the electronic cigarette in this embodiment is basically the same as that of the electronic cigarette in the first embodiment, except that:

[0090] like Figure 22 As shown, in this embodiment, the upper end of the microphone compartment 92 extends upward and forms a hollow sleeve 96. A microphone connection hole 93 is formed inside the sleeve 96, and a connection channel penetrates the inner and outer surfaces of the sleeve 96 and communicates with the microphone connection hole 93. In the locked state, the connection channel is covered by the outer peripheral surface of the threaded rotating post 70, and the microphone connection hole 93 is not connected to the connection channel; in the unlocked state, the connection channel is at least partially exposed and communicates with the microphone connection hole 93.

[0091] In this embodiment, the sleeve 96 extends into the microphone cavity 94, with its upper end protruding from the microphone compartment 92. A connecting airway is formed on the side wall of the exposed upper part of the sleeve 96, and this connecting airway can be a through-hole-shaped air guide hole 97. When the electronic cigarette is not in use, the fan assembly 60 can be rotated, causing the threaded rotating column 70 to move downwards, thereby blocking the entire air guide hole 97 from its outer circumferential surface. This locks the electronic cigarette, cutting off the airflow path between the microphone connection hole 93 and the air guide hole 97, keeping the air pressure in the microphone cavity 94 constant. This removes residual smoke from the mouthpiece channel 13 while also providing a child lock function to prevent children from imitating adults using electronic cigarettes. It is understood that the connecting airway can also be a channel structure such as a through groove penetrating the inner and outer surfaces of the sleeve 96.

[0092] 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.

[0093] 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.
