Description

Technical Field

[0001] The invention relates to the technical field of cigarette substitutes, in particular to an electronic cigarette with automatic oil core separation. Background Art

[0002] An electronic atomizer is an electronic product that imitates cigarettes and can atomize tobacco oil into smoke for users to inhale. Due to the similar taste and convenience of inhalation as cigarettes, electronic atomizers have been rapidly promoted and used.

[0003] Existing electronic atomization devices generally include a battery host and an atomizer. The atomizer is the smoke generating part of the electronic atomization device. The atomizer stores smoke oil, and high temperature will cause the smoke oil to atomize and form smoke. The battery host is the control center and power supply part of the electronic atomization device. The atomizer core is usually soaked in smoke oil or wrapped with oil storage cotton. The smoke oil passes through the oil inlet hole set on the atomizer core, and the capillary force provided by the oil guide cotton sucks the smoke oil to the heating wire. When the power is turned on, the heating wire generates high-temperature atomized smoke oil.

[0004] Throughout the life cycle of the atomizer core, oil leakage is always one of the problems that bothers users, seriously affecting user experience and usage costs. To solve the oil leakage problem, an oil core separation structure is usually set in the electronic atomizer device, that is, the smoke oil and the atomizer core are kept separate when not in use, isolating the contact and oil conduction between the two. The usual oil core separation technology is mostly manual one-time isolation through a mechanical structure, or repeated isolation. An isolation piece is set in the oil tank on the periphery of the atomizer core, and an external force is applied to make it move axially or radially, so that the smoke oil and the atomizer core are separated or connected.

[0005] However, one-time isolation can only solve the problem of oil core separation before use, but cannot solve the problem of oil core separation during and after use; repeated use will cause uneven force on the isolation parts due to different users and different usage conditions, and the accuracy of oil output is not high, which can easily cause deformation of internal parts of the atomizer and affect its sealing performance, and also affect the use effect; and it requires manual operation by the user, and it is easy to forget to close it due to negligence, resulting in oil leakage; the movement of the isolation parts in the oil tank will also cause the smoke oil to be squeezed, and even squeezed out to the atomizer core, causing the smoke oil on the atomizer core to be too saturated and leak.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0025] Please refer to Figure 1 , which is a schematic diagram of the structure of the electronic cigarette with automatic oil core separation in an embodiment.

[0026] The electronic cigarette with automatic oil core separation includes an atomizer 10 and a battery main unit 20. The atomizer 10 is an aerosol generating device of the electronic cigarette, which is used to generate heat under the condition of being 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 electronic cigarette. The battery 26 provides electric energy for the entire circuit of the electronic cigarette, so that the control center is powered on to control the operation of each component in the circuit, enabling the atomizer 10 to be powered on and generate heat; the atomizer 10 is adapted to the battery main unit 20.

[0027] Specifically, please refer to Figure 2 , the atomizer 10 includes a housing 12, an atomization component 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 encloses a hollow cavity inside the housing 12. The atomization component 14 is arranged in the hollow cavity. The atomization component 14 includes an isolation sleeve 142, an oil guiding element 144 and a heating element 146. The oil guiding element 144 is arranged in the isolation sleeve 142 after covering the heating element 146. The hollow cavity is divided into an oil storage cavity 124 and an atomization cavity 126 by the isolation sleeve 142. The isolation sleeve 142 is provided with an oil guiding hole 1422 communicating the oil storage cavity 124 and the atomization cavity 126; a first limiting hole 127 and a second limiting hole 162 are respectively arranged inside the mouthpiece end 122 of the housing 12 and the base 16. Two ends of the isolation sleeve 142 are respectively inserted into the first limiting hole 127 and the second limiting hole 162, and the isolation sleeve 142 can reciprocate along the first limiting hole 127 and the second limiting hole 162; it further includes an electric drive assembly 30. The electric drive assembly 30 includes a power unit 32 and a transmission unit 34. The power unit 32 is in transmission connection with the transmission unit 34. One end of the isolation sleeve 142 is fixed to the transmission unit 34. The power unit 32 drives the atomization component 14 to reciprocate in the hollow cavity through the transmission unit 34 to control the on-off of the oil storage cavity 124 and the atomization cavity 126.

[0028] By setting the reciprocating atomization component 14 and the electric drive assembly 30 that can drive the atomization component 14 to reciprocate, the electronic cigarette with automatic oil core separation provides power for the transmission unit 34 through the electric control of the power unit 32, drives the atomization component 14 to reciprocate within a preset range, so as to control the connection and disconnection between the oil storage cavity 124 and the atomization cavity 126. Without manually applying external force, the atomization component 14 can automatically reciprocate, realizing the connection and isolation between the atomization cavity 126 and the oil storage cavity 124, and can realize repeated on-off isolation; at the same time, because the reciprocating motion of the atomization component 14 is within the atomization cavity 126 and does not involve causing pressure changes to the e-liquid in the oil storage cavity 124, there will be no pressure on the e-liquid in the oil storage cavity 124 due to the reciprocating motion, and there will be no situation where a small amount of e-liquid is extruded out of the oil guiding hole 1422, resulting in oil leakage, thereby improving the sealing performance of the electronic cigarette.

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

[0030] Please refer to Figure 2 , in this embodiment, the drive unit 34 includes a drive rod 342. One end of the drive rod 342 is in transmission connection with the power unit 32, and the other end of the drive rod 342 is fixed to the isolation sleeve 142. The drive rod 342 converts the rotational output of the power unit 32 into the axial movement of the isolation sleeve 142, so that the atomization assembly 14 makes a reciprocating movement within a preset range along with the movement of the power unit 32.

[0031] In this embodiment, the power unit 32 includes a motor 322, an output rotating shaft 324, a reduction gear, and a packaging shell. The reduction gear is respectively connected to the motor 322 and the output rotating shaft 324, and the motor 322, the output rotating shaft 324, and the reduction gear are all arranged in the packaging shell. One end of the output rotating shaft 324 extends out of the packaging shell, and the output rotating shaft 324 is in transmission connection with the drive rod 342.

[0032] When the motor 322 operates, it transmits power to the output rotating shaft 324 through the reduction gear, and the output rotating shaft 324 drives the drive rod 342 to move. This can increase the stability and reliability of the transmission, and there is no need to manually apply external force, so that the atomization assembly 14 can move with uniform force each time. It can avoid problems such as movement blockage, deformation affecting the sealing performance, and the stability and accuracy of the oil output affected by uneven force, improving the use performance and service life, and also improving the user's inhalation experience. Among them, the motor 322 is preferably a stepper motor 322.

[0033] Among them, one end of the transmission rod 342 is provided with an external thread, and the output shaft 324 is provided with an internal thread, and the external thread is engaged with the internal thread, so the rotation of the shaft can drive the transmission rod 342 to move up and down. The transmission rod 342 and the output shaft 324 are engaged through the thread, and the structure is simple and compact, the efficiency is high, the reliability is good, the flow rate is stable and uniform, and it is conducive to outputting stable and uniform power, so that the movement performance and speed of the piston valve are stable, so that the force is uniform and the oil output is stable. Of course, in another embodiment, one end of the transmission rod 342 can also be provided with an internal thread, and the output shaft 324 can be provided with an external thread, and the external thread is engaged with the internal thread.

[0034] See also Figure 2 In this embodiment, an end cover 18 is provided in the hollow cavity near the suction nozzle end 122, and the end cover 18, the isolation sleeve 142 and the base 16 enclose the oil storage cavity 124, and the first limiting hole 127 is provided in the end cover 18. On the one hand, the end cover 18 can separate and seal the oil storage cavity 124 inside the housing 12; on the other hand, a certain space can be separated in the irregular area between the end cover 18 and the suction nozzle for arranging the oil absorbing cotton 1282 and the airflow sensor 22.

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

[0036] Furthermore, the end cover 18 is provided with a limiting groove 184, in which a first sealing member 186 is embedded, and the first sealing member 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 member 186. The sealing performance of the oil storage chamber 124 is improved, and the sealing performance between the isolation sleeve 142 and the first limiting hole 127 is also improved, and the possibility of oil leakage is completely avoided; at the same time, because the isolation sleeve 142 will reciprocate according to the drive of the electric transmission component 30, the first sealing member 186 avoids the wear caused by the movement between the isolation sleeve 142 and the first limiting hole 127, and the material of the first sealing member 186 is preferably a silicone sealing material. A second sealing member 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 member 164. Similarly, the second sealing member 164 also improves the sealing performance between the isolation sleeve 142 and the second limiting hole 162, avoiding wear between the isolation sleeve 142 and the second limiting hole 162 due to movement. The material of the second sealing member 164 is preferably a silicone sealing material.

[0037] See also Figure 2, in this embodiment, a first accommodating cavity 128 is provided between the end cap 18 and the mouthpiece. An oil-absorbing cotton 1282 is disposed in the first accommodating cavity 128, and a through hole 1284 communicating the atomizing cavity 126 with the mouthpiece is provided in the middle of the oil-absorbing cotton 1282. When the high-temperature smoke forms condensate on the inner wall of the atomizing cavity 126, the oil-absorbing cotton 1282 can absorb the condensate, preventing the condensate from being inhaled by the user into the mouth and affecting the smoking experience.

[0038] In this embodiment, a second accommodating cavity 129 is provided between the end cap 18 and the mouthpiece. An airflow sensor 22 is disposed in the second accommodating cavity 129, and a trigger air passage 1292 communicating with the outside is independently provided beside the mouthpiece. The trigger air passage 1292 is communicated with the airflow sensor 22. The airflow sensor 22 is disposed in the second accommodating cavity 129 close to the mouthpiece, which can shorten the length of the trigger air passage 1292 and is beneficial to quickly trigger and start the electronic cigarette. The trigger air passage 1292 is independently provided and not communicated with the atomizing cavity 126, which can prevent the condensate formed in the atomizing cavity 126 from entering the trigger air passage 1292, and even prevent the condensate from corroding the airflow sensor 22, which is beneficial to maintaining the accuracy and service life of the airflow sensor 22.

[0039] Please refer to Figure 2 , in this embodiment, the battery main body 20 includes a main control board 24, a battery 26 and an airflow sensor 22. The main control board 24 is provided with a micro control unit and a motor 322 control module. The airflow sensor 22 triggers the main control board 24 to be powered on. The micro control unit issues an instruction to the motor 322 control module to drive the motor 322 to start. The atomizing assembly 14 is driven to move through the transmission unit 34, so that the atomizing assembly 14 controls the movement of the transmission unit 34 according to the opening and closing of the airflow sensor 22, and controls the on-off of the oil storage cavity 124 and the atomizing cavity 126. That is, when the user sucks, the electric drive assembly 30 is automatically started, and the power unit 32 drives the atomizing assembly 14 to move to the top dead center, so that the oil guiding hole 1422 conducts the oil storage cavity 124 and the oil guiding element 144; when the sucking stops, the power unit 32 drives the atomizing assembly 14 to move to the bottom dead center, so that the oil storage cavity 124 and the oil guiding element 144 are separated; the automatic separation between the oil storage cavity 124 and the oil guiding element 144 according to sucking is realized, which is convenient to use, safe and reliable.

[0040] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered as the scope recorded in this specification.

[0041] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
