Description

Technical Field

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

[0002] Electronic atomizing devices are electronic products that mimic cigarettes, atomizing e-liquid into vapor for users to inhale. Due to their similar taste and ease of use to cigarettes, electronic atomizing devices have been rapidly promoted and used.

[0003] Existing electronic atomizing devices generally consist of a battery-operated main unit and an atomizer. The atomizer is the vapor-generating part of the electronic atomizing device, containing e-liquid that is atomized at high temperatures to form vapor. The battery-operated main unit is the control center and power supply unit of the electronic atomizing device. The atomizer coil is usually immersed in e-liquid or wrapped in a wicking pad. The e-liquid is drawn into the heating coil through the wicking pad via an inlet, and the capillary force provided by the wicking pad draws the e-liquid to the heating coil. When electricity is applied, the heating coil generates high-temperature atomization of the e-liquid.

[0004] Throughout the entire lifespan of the atomizer coil, leakage remains a persistent problem for users, severely impacting user experience and operating costs. To address this issue, electronic atomizers typically incorporate a coil-electrode separation structure. This structure keeps the e-liquid separate from the coil when not in use, preventing contact and wicking between them. Common coil-electrode separation technologies include manual one-time isolation via mechanical structures or repeated isolation after multiple uses. This involves placing an isolator within the e-liquid reservoir around the coil and applying external force to allow it to move axially or radially, thus separating or connecting the e-liquid to the coil.

[0005] However, a one-time isolation device can only solve the problem of oil-coil separation before use, not during or after use. Repeated use can lead to uneven stress on the isolation device due to different users and usage conditions, resulting in low accuracy of e-liquid output. This can easily cause deformation of internal atomizer components, affecting their sealing performance and overall performance. Furthermore, it requires manual operation by the user, which can easily lead to leakage if the device is forgotten to be turned off. The movement of the isolation device within the e-liquid tank can also cause the e-liquid to be squeezed, even squeezed out onto the atomizer coil, resulting in oversaturation and leakage. Utility Model Content

[0013] In one embodiment, the end cap is provided with a limiting groove, and a first sealing element is embedded in the limiting groove. The first sealing element is also embedded in the inner wall of the first limiting hole, so that the isolation sleeve and the first limiting hole are sealed by the first sealing element. A second sealing element is provided at the second limiting hole, and the isolation sleeve and the second limiting hole are sealed by the second sealing element.

[0014] In one embodiment, the power unit includes a motor, an output shaft, a reduction gear, and a housing.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] Please see Figure 1 This is a schematic diagram of the structure of an electronic cigarette with automatic oil-core separation in one embodiment.

[0026] The automatic coil-separation e-cigarette includes an atomizer 10 and a battery main unit 20. The atomizer 10 is the aerosol generator of the e-cigarette, used to generate heat when powered on, so that the e-liquid in the atomizer 10 forms an aerosol for the user to inhale. The battery main unit 20 is the control center and power supply center of the e-cigarette. The battery 26 provides power to the entire circuit of the e-cigarette, so that the control center is powered on to control the operation of various components in the circuit, so that the atomizer 10 can be powered on and generate heat. The atomizer 10 is compatible with the battery main unit 20.

[0027] For details, please refer to Figure 2 The atomizer 10 includes a housing 12, an atomizing assembly 14, and a base 16. The housing 12 includes a mouthpiece end 122 and an open end. The base 16 is inserted into the open end of the housing 12 and forms a hollow cavity inside the housing 12. The atomizing assembly 14 is disposed within the hollow cavity. The atomizing assembly 14 includes an isolation sleeve 142, an oil guiding element 144, and a heating element 146. The oil guiding element 144 covers the heating element 146 and is disposed within the isolation sleeve 142. The hollow cavity is divided into an oil storage chamber 124 and an atomizing chamber 126 by the isolation sleeve 142. The isolation sleeve 142 has an oil guiding hole 1422 communicating with the oil storage chamber 124 and the atomizing chamber 126. The mouthpiece end 122 of the housing 12 and the base 16 are respectively provided with a first limiting hole 127 and a second limiting hole 162. The two ends of the isolation sleeve 142 are respectively inserted into... The isolation sleeve 142 is located at the first limiting hole 127 and the second limiting hole 162, and can reciprocate along the first limiting hole 127 and the second limiting hole 162; it also includes an electric transmission assembly 30, which includes a power unit 32 and a transmission unit 34. The power unit 32 is connected to the transmission unit 34. One end of the isolation sleeve 142 is fixed to the transmission unit 34. The power unit 32 drives the atomizing assembly 14 to reciprocate in the hollow cavity through the transmission unit 34 to control the opening and closing of the oil storage chamber 124 and the atomizing chamber 126.

[0028] This automatic coil-separation e-cigarette features a reciprocating atomizing component 14 and an electric drive component 30 that drives the atomizing component 14 in this reciprocating motion. An electric control power unit 32 provides power to the drive unit 34, causing the atomizing component 14 to reciprocate within a preset range. This controls the connection and disconnection between the e-liquid storage chamber 124 and the atomizing chamber 126. No manual external force is required for the atomizing component 14 to automatically reciprocate, achieving connection and isolation between the atomizing chamber 126 and the e-liquid storage chamber 124, allowing for repeated on / off isolation. Furthermore, because the reciprocating motion of the atomizing component 14 occurs within the atomizing chamber 126 and does not cause pressure changes in the e-liquid within the e-liquid storage chamber 124, it prevents pressure buildup and avoids leakage of e-liquid from the wicking hole 1422, thus improving the e-cigarette's sealing performance.

[0029] More specifically, in the initial state, to prevent oil leakage, the atomizing chamber 126 is isolated from the oil storage chamber 124. At this time, the oil guide hole 1422 is located below the second limiting hole 162 and is not connected to the atomizing chamber 126 and the oil storage chamber 124. When the electronic cigarette is inhaled, the electric drive unit 34 is powered on and operates. At this time, the electric drive unit 34 drives the atomizing component 14 to move towards the mouthpiece end 122 until it moves to the preset position. As the atomizing component 14 moves, the oil guide on the isolation sleeve 142... The hole 1422 also moves, connecting the oil storage chamber 124 with the atomizing chamber 126. The e-liquid in the oil storage chamber 124 flows through the oil guide hole 1422 to the oil guide element 144, and is atomized into smoke by the heating element 146 at high temperature for the user to inhale. When the e-cigarette is not needed, the electric drive unit 34 drives the atomizing component 14 to move towards the base 16 until it stops. At this time, the oil guide hole 1422 is separated from the atomizing chamber 126 and the oil storage chamber 124 again, returning to the initial state.

[0030] Please see Figure 2 In this embodiment, the transmission unit 34 includes a transmission rod 342, one end of which is connected to the power unit 32, and the other end of which is fixed to the isolation sleeve 142. The transmission rod 342 converts the rotational output of the power unit 32 into the axial movement of the isolation sleeve 142, causing the atomizing component 14 to reciprocate within a preset range as the power unit 32 moves.

[0031] In this embodiment, the power unit 32 includes a motor 322, an output shaft 324, a reduction gear, and a housing. The reduction gear is connected to the motor 322 and the output shaft 324 respectively. The motor 322, the output shaft 324, and the reduction gear are all housed inside the housing. One end of the output shaft 324 extends out of the housing and is connected to the transmission rod 342.

[0032] When the motor 322 is working, it transmits power to the output shaft 324 via a reduction gear. The output shaft 324 then drives the transmission rod 342, increasing the stability and reliability of the transmission. It eliminates the need for manual external force, ensuring that the atomizing component 14 moves evenly with each stroke. This avoids problems caused by uneven force, such as movement obstruction, deformation affecting sealing performance, and impacting the stability and accuracy of oil output. This improves performance and lifespan, and enhances the user's vaping experience. Preferably, the motor 322 is a stepper motor.

[0033] In this design, one end of the transmission rod 342 is provided with an external thread, and the output shaft 324 is provided with an internal thread. The external and internal threads mesh together, so rotating the shaft can drive the transmission rod 342 to move up and down. The threaded engagement between the transmission rod 342 and the output shaft 324 results in a simple, compact, efficient, and reliable structure with stable and uniform flow, which is beneficial for outputting stable and uniform power. This ensures stable piston valve movement and speed, resulting in uniform force distribution and stable oil output. Alternatively, in another embodiment, one end of the transmission rod 342 may be provided with an internal thread, and the output shaft 324 may be provided with an external thread, with the external and internal threads meshing together.

[0034] Please see Figure 2 In this embodiment, an end cap 18 is provided in the hollow cavity near the nozzle end 122. The end cap 18, the isolation sleeve 142, and the base 16 form an oil storage cavity 124, and a first limiting hole 127 is provided in the end cap 18. The end cap 18 can isolate and seal the oil storage cavity 124 inside the housing 12; on the other hand, it can separate a certain space in the irregular area between the end cap 18 and the nozzle for setting up the oil-absorbing cotton 1282 and the airflow sensor 22.

[0035] The end cap 18 is further provided with a limiting boss 182 inside the first limiting hole 127. When the isolation sleeve 142 is connected to the oil storage chamber 124 and the atomizing chamber 126, it abuts against the limiting boss 182. The isolation sleeve 142 abuts against the limiting boss 182 when the atomizing chamber 126 is connected to the oil storage chamber 124, which is used to limit the movement of the isolation sleeve 142.

[0036] Furthermore, the end cap 18 is provided with a limiting groove 184, in which a first sealing element 186 is embedded, and the first sealing element 186 is embedded in the inner wall of the first limiting hole 127, so that the isolation sleeve 142 and the first limiting hole 127 are sealed by the first sealing element 186. This improves the sealing performance of the oil storage cavity 124 and also improves the sealing performance between the isolation sleeve 142 and the first limiting hole 127, completely avoiding the possibility of e-liquid leakage; at the same time, since the isolation sleeve 142 will reciprocate under the drive of the electric transmission assembly 30, the first sealing element 186 avoids wear caused by the movement between the isolation sleeve 142 and the first limiting hole 127. The material of the first sealing element 186 is preferably silicone sealing material. A second sealing element 164 is provided at the second limiting hole 162, and the isolation sleeve 142 and the second limiting hole 162 are sealed by the second sealing element 164. Similarly, the second seal 164 also improves the sealing performance between the isolation sleeve 142 and the second limiting hole 162, avoiding wear caused by movement between the isolation sleeve 142 and the second limiting hole 162. The material of the second seal 164 is preferably silicone sealing material.

[0037] Please see Figure 2In this embodiment, a first receiving cavity 128 is provided between the end cap 18 and the mouthpiece. Oil-absorbing cotton 1282 is provided inside the first receiving cavity 128, and a through hole 1284 is provided in the middle of the oil-absorbing cotton 1282, connecting the atomizing cavity 126 and the mouthpiece. When high-temperature smoke cools and condenses on the inner wall of the atomizing cavity 126, the oil-absorbing cotton 1282 can absorb the condensate, preventing the user from inhaling the condensate and affecting the smoking experience.

[0038] In this embodiment, a second receiving cavity 129 is provided between the end cap 18 and the mouthpiece. An airflow sensor 22 is housed within the second receiving cavity 129, and a trigger airway 1292, communicating with the outside, is independently provided next to the mouthpiece. The trigger airway 1292 is connected to the airflow sensor 22. The airflow sensor 22 is located within the second receiving cavity 129 near the mouthpiece, which shortens the length of the trigger airway 1292, facilitating rapid activation of the electronic cigarette. Furthermore, the trigger airway 1292 is independently provided and not connected to the atomizing chamber 126, preventing condensate formed in the atomizing chamber 126 from entering the trigger airway 1292, and preventing condensate from corroding the airflow sensor 22. This helps maintain the accuracy and lifespan of the airflow sensor 22.

[0039] Please see Figure 2 In this embodiment, the battery host 20 includes a main control board 24, a battery 26, and an airflow sensor 22. The main control board 24 is equipped with a microcontroller unit and a motor 322 control module. The airflow sensor 22 triggers the main control board 24 to be powered on. The microcontroller unit sends a command to the motor 322 control module to drive the motor 322 to start. The motor 322 is driven to move through the transmission unit 34, so that the atomizing component 14 controls the movement of the transmission unit 34 according to the opening and closing of the airflow sensor 22, thereby controlling the opening and closing of the oil storage chamber 124 and the atomizing chamber 126. That is, when the user inhales, the electric drive assembly 30 is automatically activated, and the power unit 32 drives the atomizing assembly 14 to move to the upper dead point, so that the oil guide hole 1422 connects the oil storage chamber 124 and the oil guide element 144; when inhalation stops, the power unit 32 drives the atomizing assembly 14 to move to the lower dead point, so that the oil storage chamber 124 and the oil guide element 144 are isolated; thus, the oil storage chamber 124 and the oil guide element 144 are automatically isolated according to inhalation, which is convenient to use and safe and reliable.

[0040] 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.

[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
