Technical Field

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

[0002] Most existing e-cigarettes use a motor to move the atomizer coil assembly. The coil assembly's oil inlet then draws oil into the e-liquid tank. If the motor is not activated during inhalation, the oil and coil will not separate in time, resulting in insufficient and inefficient oil supply. If the motor is activated during inhalation, the motor consumes power, and the atomizer coil assembly's power is insufficient, leading to poor atomization and taste, thus affecting the user experience. Utility Model Content

[0003] Therefore, it is necessary to provide an electronic cigarette that addresses the technical problems of existing electronic cigarettes, which mostly rely on a motor to move the atomizing coil assembly. The atomizing coil assembly's oil inlet then enters the oil tank, and if the motor is not driven during inhalation, the oil and coil will not separate in time, resulting in insufficient and inefficient oil supply. If the motor is driven during inhalation, the motor consumes power, and the atomizing coil assembly's power is insufficient, leading to poor atomization and taste, thus affecting the user experience.

[0004] This utility model provides an electronic cigarette, which includes: a shell, a driving assembly, and an atomizing core assembly. The shell includes a shell body and a mouthpiece. The shell body is divided into an oil storage chamber and an atomizing chamber by the atomizing core assembly. The mouthpiece has a smoking channel communicating with the atomizing chamber. The atomizing core assembly includes a sleeve, an oil guide, an oil storage component, and a heating element. The sleeve has an oil inlet hole. The sleeve sleeve covers the oil guide and the oil storage component. The oil storage component and the oil guide are arranged along the axial direction of the sleeve, and the oil storage component contacts the oil guide. The oil guide is located at the oil inlet hole. The heating element is fixed to the inner wall of the oil guide. The driving assembly is driven by the sleeve and drives the atomizing core assembly to move in a direction close to or away from the mouthpiece. Oil is introduced when the oil inlet hole communicates with the oil storage chamber, and oil is cut off when the oil inlet hole is separated from the oil storage chamber.

[0005] In one embodiment, the electronic cigarette further includes a first seal and a second seal, both of which surround the sleeve and are located at the top and bottom of the oil storage chamber, respectively. The top of the atomizing chamber is provided with a clearance cavity communicating with the smoking channel, and the sleeve can move axially within the atomizing chamber and the clearance cavity.

[0006] In one embodiment, the oil inlet includes a first hole and a plurality of second holes, the first hole and each of the second holes being uniformly arranged along the circumferential direction of the sleeve, and the position of the first hole relative to the drive component being higher than the position of the second hole relative to the drive component.

[0007] In one embodiment, the first hole is positioned 0.1 mm to 1 mm higher than the second hole.

[0008] In one embodiment, the first hole includes a circular hole and a square hole communicating with the circular hole, the square hole being used for air replenishment.

[0009] In one embodiment, the square hole is located in a non-heating area on the sleeve.

[0010] In one embodiment, the driving assembly includes a drive motor, a first transmission component, and a second transmission component. The drive motor, the first transmission component, and the second transmission component are sequentially connected for transmission. The second transmission component is fixed to the sleeve. The drive motor drives the first transmission component to move the second transmission component and the sleeve.

[0011] In one embodiment, the electronic cigarette further includes an oil-absorbing cotton, which is disposed within the casing and communicates with the smoking channel.

[0012] In one embodiment, the electronic cigarette further includes an airflow sensor disposed within the housing, and the mouthpiece has a trigger airway connecting the outside to the airflow sensor.

[0013] In one embodiment, the atomizing core assembly further includes an outer tube and an oil storage cotton, the outer tube being sleeved over the sleeve, the oil storage cotton being located between the outer tube and the sleeve, and the outer tube having an oil inlet hole, the diameter of which is smaller than the diameter of the oil inlet hole.

[0014] Implementing the embodiments of this utility model will have the following beneficial effects:

[0015] The electronic cigarette of this invention features a sleeve housing an oil guide and an oil reservoir. The oil reservoir and oil guide are arranged axially along the sleeve, with the oil reservoir contacting the oil guide. The oil guide is located at the oil inlet. A heating element is fixed to the inner wall of the oil guide. A drive assembly is connected to the sleeve and drives the atomizing coil assembly to move towards or away from the mouthpiece. Oil enters when the oil inlet is connected to the oil reservoir, and stops when the oil inlet is disconnected from the oil reservoir. By incorporating the oil reservoir, the drive assembly drives the atomizing coil. During the movement of the components, the oil inlet enters the oil storage chamber, and the e-liquid flows through the oil inlet to wet the wicking component. The e-liquid on the wicking component then wets the oil storage component, ensuring a sufficient supply of e-liquid to the atomizer core component. Then, the drive component drives the atomizer core component to move in the opposite direction, causing the oil inlet to detach from the oil storage chamber. In this way, during the vaping process, the oil storage component can directly supply e-liquid without the need for the motor to participate in the e-liquid supply. The motor does not consume power, increasing the power of the atomizer core component, improving the atomization effect and flavor, and thus enhancing the user experience.

[0035] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0036] Please combine them together Figures 1 to 5 The electronic cigarette provided by this utility model will now be described.

[0037] The electronic cigarette includes: a shell 1, a driving assembly 2, and an atomizing core assembly 3. The shell 1 includes a shell body 11 and a mouthpiece 12. The shell body 11 is divided into an oil storage chamber 111 and an atomizing chamber 112 by the atomizing core assembly 3. The mouthpiece 12 has a smoking channel 121 that communicates with the atomizing chamber 112. The atomizing core assembly 3 includes a sleeve 31, an oil guide 32, an oil storage component 33, and a heating element 34. The sleeve 31 is provided with an oil inlet 311, and the sleeve 31 is fitted with the oil guide 32 and the oil storage component. 33. The oil storage component 33 and the oil guide component 32 are arranged along the axial direction of the sleeve 31, and the oil storage component 33 contacts the oil guide component 32. The oil guide component 32 is located at the oil inlet 311. The heating element 34 is fixed to the inner wall of the oil guide component 32. The drive assembly 2 is connected to the sleeve 31 and drives the atomizing core assembly 3 to move in the direction close to or away from the mouthpiece 12. When the oil inlet 311 is connected to the oil storage chamber 111, oil is introduced. When the oil inlet 311 is separated from the oil storage chamber 111, oil is cut off.

[0038] It is understood that the sleeve 31 of the electronic cigarette is fitted with an oil guide 32 and an oil reservoir 33. The oil reservoir 33 and the oil guide 32 are arranged along the axial direction of the sleeve 31, and the oil reservoir 33 contacts the oil guide 32. The oil guide 32 is located at the oil inlet 311. The heating element 34 is fixed to the inner wall of the oil guide 32. The drive assembly 2 is connected to the sleeve 31 and drives the atomizing core assembly 3 to move in a direction close to or away from the mouthpiece 12. When the oil inlet 311 is connected to the oil reservoir 111, oil is introduced; when the oil inlet 311 is separated from the oil reservoir 111, oil is cut off. By setting the oil reservoir 33, the drive assembly... During the movement of the atomizing core assembly 3 driven by component 2, the oil inlet 311 enters the oil storage chamber 111. E-liquid flows through the oil inlet 311 and wets the wicking component 32. The e-liquid on the wicking component 32 wets the oil storage component 33, thus ensuring sufficient e-liquid supply to the atomizing core assembly 3. Then, the driving component 2 drives the atomizing core assembly 3 to move in the opposite direction, causing the oil inlet 311 to disengage from the oil storage chamber 111. In this way, during the vaping process, the oil storage component 33 can directly supply e-liquid without the need for the motor to participate in the e-liquid supply. The motor does not consume power, increasing the power of the atomizing core assembly 3, improving the atomization effect and flavor, and thus improving the user experience.

[0039] It should be noted that the oil inlet 311 is located at the bottom of the sleeve 31. Initially, the oil inlet 311 is located outside the oil storage chamber 111. The drive assembly 2 drives the atomizing core assembly 3 to move in the direction close to the mouthpiece 12, so that the oil inlet 311 enters the oil storage chamber 111. The e-liquid in the oil storage chamber 111 wets the oil guide 32 through the oil inlet 311, and the oil guide 32 wets the oil storage component 33. When the oil storage component 33 is full of e-liquid, the drive assembly 2 then drives the atomizing core assembly 3 to move in the direction away from the mouthpiece 12, so that the oil inlet 311 leaves the oil storage chamber 111.

[0040] The heating element 34 atomizes the e-liquid on the oil guide 32, and the oil storage component 33 supplies oil to the oil guide 32. The atomized e-liquid is inhaled through the smoking channel 121. The shell body 11 is also provided with an air intake channel for air intake.

[0041] In this embodiment, the electronic cigarette also includes a first sealing element 4 and a second sealing element 5. Both the first sealing element 4 and the second sealing element 5 surround the sleeve 31 and are located at the top and bottom of the oil storage chamber 111, respectively. The top of the atomizing chamber 112 has a clearance cavity 41 communicating with the smoking channel 121. The sleeve 31 can move axially within the atomizing chamber 112 and the clearance cavity 41. By providing the first sealing element 4 and the second sealing element 5, the oil storage chamber 111 can be sealed. The axial movement of the sleeve 31 within the atomizing chamber 112 and the clearance cavity 41 prevents the e-liquid in the oil storage chamber 111 from leaking out.

[0042] In one embodiment, such as Figures 3 to 5 As shown, the oil inlet 311 includes a first hole 3111 and multiple second holes 3112. The first hole 3111 and each of the second holes 3112 are evenly arranged along the circumferential direction of the sleeve 31. The position of the first hole 3111 relative to the drive assembly 2 is higher than the position of the second holes 3112 relative to the drive assembly 2. In this way, the first hole 3111 can enter the oil storage chamber 111 first. If there is a negative pressure in the oil storage chamber 111, the first hole 3111 can indirectly replenish the oil storage chamber 111 with external air.

[0043] Specifically, the position of the first hole 3111 relative to the drive component 2 is 0.1 mm to 1 mm higher than the position of the second hole 3112 relative to the drive component 2.

[0044] In this embodiment, the first hole 3111 includes a circular hole 31111 and a square hole 31112 communicating with the circular hole 31111. The square hole 31112 is used for air replenishment. Specifically, the square hole 31112 can avoid the formation of an oil film that affects air replenishment. The square hole 31112 allows air to pass through, while the circular hole 31111 guides oil. The two do not interfere with each other, avoiding the need to provide only one hole to both guide oil from the oil storage chamber 111 and replenish air into the oil storage chamber 111, thereby avoiding conflicts.

[0045] Furthermore, the square hole 31112 is located in the non-heating area of ​​the sleeve 31. Specifically, it avoids the heating area to ensure stable e-liquid supply. Since the heating element 34 supplies e-liquid to the atomizing wicking component 32, the e-liquid in the heating area of ​​the wicking component 32 will be rapidly and continuously consumed. The non-heating area supplies e-liquid to the heating area, which will produce carbon deposits in the heating area. The square hole 31112 avoids the heating area, so that during the air supply process, the carbon deposits in the heating area will not enter the e-liquid reservoir 111, causing discoloration of the e-liquid in the reservoir 111, thus avoiding affecting the taste.

[0046] In one embodiment, such as Figure 3As shown, the drive assembly 2 includes a drive motor 21, a first transmission component 22, and a second transmission component 23. The drive motor 21, the first transmission component 22, and the second transmission component 23 are sequentially connected for transmission. The second transmission component 23 is fixed to the sleeve 31. The drive motor 21 drives the first transmission component 22, which in turn moves the second transmission component 23 and the sleeve 31. The drive motor 21 drives the first transmission component 22 to rotate. Since the first transmission component 22 and the second transmission component 23 are threadedly connected, the first transmission component 22 drives the second transmission component 23 to move along the axial direction of the atomizing chamber 112, and the second transmission component 23 in turn moves the sleeve 31.

[0047] In one embodiment, continue as follows Figure 3 As shown, the electronic cigarette also includes an oil-absorbing cotton 6, which is disposed inside the shell body 11 and connected to the smoking channel 121. When the high-temperature atomized vapor encounters the cold and forms condensate on the inner wall of the smoking channel 121, the oil-absorbing cotton 6 can absorb the condensate, preventing the condensate from being inhaled by the user and affecting the smoking experience.

[0048] In one embodiment, continue as follows Figure 3 As shown, the electronic cigarette also includes an airflow sensor 7, which is disposed within the housing body 11. The mouthpiece 12 has a trigger airway 122 that connects to the outside and the airflow sensor 7. The airflow sensor 7 is located within the housing body 11 near the mouthpiece 12, which shortens the distance between the trigger airway 122 and the airflow sensor 7, facilitating rapid activation of the electronic cigarette. The separate trigger airway 122 prevents condensate generated during high-temperature atomization from corroding the airflow sensor 7, thus extending its service life.

[0049] In one embodiment, continue as follows Figure 3 As shown, the electronic cigarette also includes a battery assembly 8, which is used for power supply. The battery assembly 8 includes a battery and a main control board. The battery powers the main control board, which in turn powers and controls the internal components of the electronic cigarette.

[0050] In one embodiment, such as Figure 6 and Figure 7 As shown, the atomizing core assembly 3 also includes an outer tube 35 and an oil storage cotton 36. The outer tube 35 is fitted with a sleeve 31, and the oil storage cotton 36 is located between the outer tube 35 and the sleeve 31. The outer tube 35 is provided with an oil inlet hole 351, and the diameter of the oil inlet hole 351 is smaller than the diameter of the oil inlet hole 311.

[0051] Specifically, the initial position oil inlet 351 and oil inlet 311 are located outside the oil storage chamber 111. The drive assembly 2 drives the atomizing core assembly 3 to move in the direction close to the mouthpiece 12, so that the oil inlet 351 enters the oil storage chamber 111. The e-liquid in the oil storage chamber 111 soaks the oil storage cotton 36 through the oil inlet 351. The e-liquid on the oil storage cotton 36 soaks the oil guide 32 through the oil inlet 311. The oil guide 32 soaks the oil storage component 33. When the oil storage component 33 is full of e-liquid, the drive assembly 2 then drives the atomizing core assembly 3 to move in the direction away from the mouthpiece 12, so that the oil inlet 351 leaves the oil storage chamber 111.

[0052] The diameter of the oil inlet hole 351 is smaller than the diameter of the oil inlet hole 311. This allows the e-liquid in the oil storage chamber 111 to evenly wet the oil storage cotton 36 through the oil inlet hole 351, and the e-liquid on the oil storage cotton 36 to quickly wet the oil guide component 32 through the oil inlet hole 311.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
