Abstract
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, e-liquid leakage remains a persistent problem for users, significantly impacting user experience and operating costs. To address this issue, e-liquid-coil separation structures are typically incorporated into electronic atomizers. These structures keep the e-liquid separate from the coil when not in use, preventing contact and wicking between the two. Common e-liquid-coil separation technologies often involve manual, one-time isolation via mechanical structures or repeated isolation after multiple uses. This is achieved by using an isolator that can be moved axially or radially by applying external force, 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 oil output. This can easily cause deformation of internal atomizer components, affecting its sealing performance and thus the performance. Furthermore, it requires manual operation by the user, who may forget to turn it off due to negligence, leading to oil leakage. Utility Model Content

[0028] Please see Figure 1 This is a schematic diagram of the structure of an electronic cigarette with automatic oil-core separation in one embodiment.
[0029] The automatic coil-separation e-cigarette includes an atomizer 10 and a battery main unit 20. The atomizer 10 is the aerosol generating device of the e-cigarette, which is 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 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.
[0030] For details, please refer to Figure 1 , Figure 2 The atomizer 10 is compatible with the battery host 20. The atomizer 10 includes a housing 12, an atomizing component 14, and a base 16. The housing 12 includes a mouthpiece end 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 component 14 is disposed in the hollow cavity and divides the hollow cavity into an oil storage chamber 122 and an atomizing chamber 124. The atomizer 10 also includes an electric piston valve 18, which includes a piston assembly 182 and a power unit. The piston assembly 182 is disposed in the oil storage chamber 122 and one end extends out of the oil storage chamber 122. The power unit is connected to the piston assembly 182. The battery host 20 is provided with a clearance chamber 22. The atomizer 10 is inserted into the clearance chamber 22, and the power unit is disposed in the clearance chamber 22. The power unit drives the piston assembly 182 to perform piston movement to control the opening and closing of the oil storage chamber 122 and the atomizing component 14.
[0031] This automatic coil-separation electronic cigarette features an electric piston valve 18. The electric piston valve 18 includes a piston assembly 182 located within the oil reservoir 122 and a power unit located outside the atomizer 10. The electric control power unit provides power to the piston assembly 182, causing it to move like a piston. This controls the connection and disconnection between the oil reservoir 122 and the atomizer 10. Without the need for manual external force, the piston assembly 182 can move evenly with force each time. This avoids problems such as movement obstruction and deformation affecting sealing performance, as well as affecting the stability and accuracy of oil output caused by uneven force. This improves performance and service life, enhances the user's vaping experience, and eliminates the problem of leakage due to forgetting to turn it off, further improving the user experience.
[0032] Please see Figure 4 In this embodiment, the atomizing component 14 includes an oil guiding element 142, a heating element 144, and a separating sleeve 146. The two ends of the separating sleeve 146 are fixed to the mouthpiece end of the housing 12 and the base 16, respectively. The oil guiding element 142 covers the heating element 144 and is disposed inside the separating sleeve 146. An oil guiding hole 1462 is provided on the separating sleeve 146, and the oil guiding hole 1462 connects the oil storage chamber 122 and the oil guiding element 142. The internal space of the housing 12 is divided into an oil storage chamber 122 and an atomizing chamber 124 by a partition sleeve 146. The space inside the partition sleeve 146 is the atomizing chamber 124. The oil guiding element 142 and the heating element 144 are placed in the atomizing chamber 124. The space from the oil guiding element 142 to the mouthpiece end of the housing 12 is the area where the smoke after high-temperature atomization is mixed with the air intake of the electronic cigarette. The smoke mixes with the incoming air and then enters the mouthpiece for the user to inhale. The space outside the partition sleeve 146 is the oil storage chamber 122, which is used to store e-liquid. The oil guiding element 142 is set at the oil guiding hole 1462 opened on the partition sleeve 146. The oil guiding element 142 abuts against and blocks the oil guiding hole 1462 on the inner wall of the partition sleeve 146. The e-liquid in the oil storage chamber 122 flows to the oil guiding element 142 through the oil guiding hole 1462.
[0033] Preferably, the heating element 144 can be a cylindrical spring-shaped heating wire or a tubular heating mesh, and the oil guiding element 142 covers the heating element 144, forming a tubular shape and then inserted into the tubular partition sleeve 146. Of course, in other embodiments, it can also be a ceramic core or other materials.
[0034] In this embodiment, the piston assembly 182 includes a piston valve 1822, a piston holder 1824, and a transmission rod 1826. The piston valve 1822 is sleeved on the partition sleeve 146. One end of both the piston valve 1822 and the transmission rod 1826 is fixed to the piston holder 1824, and the other end of the transmission rod 1826 is connected to the power unit. After the power unit is energized, it transmits the power to the transmission rod 1826. The transmission rod 1826 drives the piston holder 1824 and the piston valve 1822 to perform piston movement in the partition sleeve 146, which can block or expose the oil guide hole 1462 on the wall of the partition sleeve 146. This allows control of the connection or disconnection between the oil storage chamber 122 and the oil guide element 142. That is, when the electronic cigarette needs to be used, the piston valve 1822 is controlled to expose the oil guide hole 1462, so that the oil storage chamber 122 and the oil guide element 142 are connected through the oil guide hole 1462. Figure 1 As shown; when the electronic cigarette is not needed, the control piston valve 1822 blocks the oil guide hole 1462, thus isolating the oil reservoir 122 from the oil guide element 142, as... Figure 2 As shown; it can be flexibly controlled according to actual needs to prevent oil leakage.
[0035] In this embodiment, the power unit includes a motor, an output shaft 1842, a reduction gear, and a housing. The reduction gear connects to both the motor and the output shaft 1842, and all three are housed within the housing. One end of the output shaft 1842 extends out of the housing, and the output shaft 1842 is connected to the transmission rod 1826. When the motor operates, it transmits power to the output shaft 1842 via the reduction gear. The output shaft 1842 then drives the transmission rod 1826, increasing the stability and reliability of the transmission. It also eliminates the need for manual external force, ensuring that the piston assembly 182 moves evenly with uniform force each time. This avoids problems such as movement obstruction, deformation affecting sealing performance, and impacting the stability and accuracy of oil output caused by uneven force, thus improving performance, service life, and the user's suction experience. Preferably, a stepper motor is used.
[0036] In this embodiment, one end of the transmission rod 1826 is provided with an external thread, and the output shaft 1842 is provided with an internal thread. The external thread and the internal thread are engaged, so the rotation of the shaft can drive the transmission rod 1826 to move up and down. The transmission rod 1826 and the output shaft 1842 are engaged by threads, resulting in a simple and compact structure, high efficiency, good reliability, and stable and uniform flow. This is beneficial for outputting stable and uniform power, making the piston valve 1822's motion performance and speed stable, thus ensuring uniform force and stable oil output. Of course, in another embodiment, one end of the transmission rod 1826 may also be provided with an internal thread, and the output shaft 1842 may be provided with an external thread, with the external thread and the internal thread engaging.
[0037] In this embodiment, the outer wall of the separator sleeve 146 is provided with a first mounting groove 1464 and an O-ring seal 1466. The first mounting groove 1464 is located between the oil guide hole 1462 and the mouthpiece end of the housing 12, and the top of the first mounting groove 1464 protrudes from the outer wall of the separator sleeve 146. The O-ring seal 1466 is interference-fitted in the first mounting groove 1464. The O-ring seal 1466 is interference-fitted with the inner wall of the piston valve 1822, and a gap is formed between the outer wall of the separator sleeve 146 and the inner wall of the piston valve 1822 to form an openable and closable e-liquid spare chamber 1468. The arrangement and cooperation of the first mounting groove 1464 and the O-ring 1466 serve two purposes. First, it ensures that the inner wall of the piston valve 1822 and the outer wall of the separator sleeve 146 are only connected through the oil guide hole 1462. This prevents oil leakage from the gap between the inner wall of the piston valve 1822 and the outer wall of the separator sleeve 146, which would otherwise result in poor sealing and prevent the complete isolation of the oil storage chamber 122 from being achieved when it is necessary to isolate the oil guide element 142. Second, it allows the inner wall of the piston valve 1822 and the outer wall of the separator sleeve 146 to form a spare e-liquid chamber 1468 that can hold a small amount of e-liquid. After the piston valve 1822 completely isolates the oil storage chamber 122, the spare e-liquid chamber 1468 can store a small amount of e-liquid. This can provide the required e-liquid to the oil guide element 142 when the electric piston valve 18 is first started and the e-liquid supply is insufficient, thus preventing the oil guide element 142 from burning dry or scorching due to insufficient e-liquid supply, improving the inhalation experience and extending the lifespan of the atomizer 10.
[0038] Please see Figure 3 In this embodiment, the piston holder 1824 is provided with a second mounting groove 1828, and the piston valve 1822 is embedded in the second mounting groove 1828; or the outer wall of the piston valve 1822 is provided with a second mounting groove 1828, and the piston holder 1824 is embedded in the second mounting groove 1828. The arrangement of the piston holder 1824 or the piston valve 1822 being embedded in the second mounting groove 1828 makes the connection between the piston valve 1822 and the piston holder 1824 more secure. When the piston holder 1824 drives the piston valve 1822 to move, it will not loosen or even fall off, ensuring the stability of the piston assembly 182.
[0039] Please see Figure 2In this embodiment, the atomizer 10 is provided with sealing silicone 19, and the base 16 is provided with a third mounting groove 162. The sealing silicone 19 is embedded in the third mounting groove 162, and one end of the separator sleeve 146 is inserted and fixed to the sealing silicone 19. The sealing silicone 19 is embedded in the third mounting groove 162 of the base 16, and both sides of the sealing silicone 19 contact the base 16 and the separator sleeve 146 respectively. On the one hand, it can seal the gap between the base 16 and the separator sleeve 146, further ensuring the sealing performance of the oil storage chamber 122 and preventing e-liquid leakage. On the other hand, in addition to the part embedded in the third mounting groove 162, the sealing silicone 19 is also provided with lugs laid along the bottom of the oil storage chamber 122. When the piston valve 1822 isolates the oil storage chamber 122 from the oil guiding element 142, the lower end of the piston valve 1822 abuts against the lugs of the sealing silicone 19, which enhances the sealing effect when isolated, that is, no e-liquid will pass through the piston valve 1822 when isolated.
[0040] Please see Figure 1 , Figure 2 and Figure 5 In this embodiment, the transmission rod 1826 passes through the sealing silicone 19 and the base 16 and connects to the output shaft 1842. The sealing silicone 19 is interference-fitted with the transmission rod 1826, while the transmission rod 1826 is clearance-fitted with the base 16. The piston valve 1822 is clearance-fitted with the separator sleeve 146, and the sealing silicone 19 is interference-fitted with both the base 16 and the separator sleeve 146. The clearance fit between the transmission rod 1826 and the base 16 is beneficial because the base 16 is made of a hard material; this clearance fit prevents wear on the base 16 during the movement of the transmission rod 1826 and also prevents the base 16 from affecting the movement of the transmission rod 1826. The clearance fit between the piston valve 1822 and the separator sleeve 146 also prevents wear between the piston valve 1822 and the separator sleeve 146 and avoids any impact on the piston movement of the piston valve 1822. The interference fits in other parts, being a combination of hard and soft materials, ensure good sealing performance without affecting the movement of the transmission rod 1826 and the piston valve 1822. The piston holder 1824 is provided with a fourth mounting groove, and the non-threaded end of the transmission rod 1826 is inserted into the fourth mounting groove, with the transmission rod 1826 and the fourth mounting groove having an interference fit. Of course, both the sealing silicone 19 and the base 16 are provided with through holes for the transmission rod 1826 to pass through.
[0041] In this embodiment, the battery host 20 includes a pneumatic switch, a main control board, and a battery. The main control board is equipped with a microcontroller unit and a motor control module. When the electronic cigarette is inhaled, the pneumatic switch senses the negative pressure, thereby activating the pneumatic switch to power the circuit. That is, the pneumatic switch triggers the main control board to power on. The microcontroller unit sends a command to the motor control module to drive the motor to start, which in turn drives the piston assembly 182 to move. The piston assembly 182 moves according to the opening and closing of the pneumatic switch, controlling the opening and closing of the oil storage chamber 122 and the oil guide hole 1462. That is, when the user is suctioning, the electric piston valve 18 is automatically activated, and the power unit drives the piston assembly 182 to move to the top dead center, so that the oil guide hole 1462 connects the oil storage chamber 122 and the oil guide element 142; when suctioning stops, the power unit drives the piston assembly 182 to move to the bottom dead center, so that the oil storage chamber 122 and the oil guide element 142 are isolated; thus, the oil storage chamber 122 and the oil guide element 142 are automatically isolated according to suction, which is convenient to use and safe and reliable.
[0042] 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.
[0043] 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.
