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] During the entire life cycle of the atomizer core, oil leakage is always one of the problems that bothers users, seriously affecting user experience and usage costs. In order 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, by setting an isolation piece and applying external force 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.

[0028] See also Figure 1 , is a schematic diagram of the structure of an automatic oil core separation electronic cigarette in one embodiment.

[0029] The electronic cigarette with automatic oil core separation includes an atomizer 10 and a battery host 20. The atomizer 10 is an aerosol generating device of the electronic cigarette, which is used to generate heat when powered on, so that the tobacco oil in the atomizer 10 forms an aerosol for the user to inhale; the battery host 20 is the control center and power supply center of the electronic cigarette. The battery provides electrical energy to the circuit of the entire electronic cigarette, so that the control center is powered on to control the various components in the circuit to work, so that the atomizer 10 can be powered on and generate heat; the atomizer 10 is compatible with the battery host 20.

[0030] For details, please refer to Figure 1 , Figure 2 The atomizer 10 is adapted to the battery host 20. The atomizer 10 includes a shell 12, an atomizer assembly 14 and a base 16. The shell 12 includes a nozzle end and an open end. The base 16 is inserted into the open end of the shell 12 and encloses a hollow cavity inside the shell 12. The atomizer assembly 14 is arranged in the hollow cavity and divides the hollow cavity into an oil storage cavity 122 and an atomizer cavity 124. The atomizer 10 also includes an electric piston valve 18. The electric piston valve 18 includes a piston assembly 182 and a power unit. The piston assembly 182 is arranged in the oil storage cavity 122, and one end extends out of the oil storage cavity 122. The power unit is connected to the piston assembly 182 in a transmission manner. The battery host 20 is provided with a clearance cavity 22. The atomizer 10 is inserted in the clearance cavity 22, and the power unit is arranged in the clearance cavity 22. The power unit drives the piston assembly 182 to perform piston movement to control the on and off of the oil storage cavity 122 and the atomizer assembly 14.

[0031] The automatic oil core separation electronic cigarette is provided with an electric piston valve 18, which includes a piston assembly 182 arranged in the oil storage chamber 122 and a power unit outside the atomizer 10. The power unit is electrically controlled to provide power to the piston assembly 182, driving the piston assembly 182 to perform piston movement to control the connection and isolation between the oil storage chamber 122 and the atomization assembly 14. There is no need to manually apply external force, so that the piston assembly 182 can move evenly each time, and the problems of movement obstruction caused by uneven force, deformation affecting the sealing performance, and oil output stability and accuracy being affected can be avoided, thereby improving the performance and service life, and also improving the user's smoking experience. There will be no problem of oil leakage caused by forgetting to close the valve, thereby improving the user's experience.

[0032] See also Figure 4 In this embodiment, the atomizer assembly 14 includes an oil guide element 142, a heating element 144 and a separation sleeve 146. The two ends of the separation sleeve 146 are respectively fixed to the nozzle end of the shell 12 and the base 16. The oil guide element 142 is arranged in the separation sleeve 146 after covering the heating element 144. The separation sleeve 146 is provided with an oil guide hole 1462, which connects the oil storage chamber 122 and the oil guide element 142. That is, the internal space of the shell 12 is divided into an oil storage chamber 122 and an atomization chamber 124 by the separation sleeve 146. The space inside the separation sleeve 146 is the atomization chamber 124. The oil guide element 142 and the heating element 144 are placed in the atomization chamber 124. The space from the oil guide element 142 to the suction nozzle end of the shell 12 is the area where the smoke after high-temperature atomization is mixed with the electronic cigarette intake air. The smoke is mixed with the incoming air and then enters the suction nozzle for the user to inhale; the space outside the separation sleeve 146 is the oil storage chamber 122, which is used to store the tobacco oil. The oil guide element 142 is arranged at the oil guide hole 1462 opened on the separation sleeve 146, and the oil guide element 142 is in contact with the inner wall of the separation sleeve 146 and blocks the oil guide hole 1462. The tobacco oil in the oil storage chamber 122 flows to the oil guide element 142 through the oil guide hole 1462.

[0033] Preferably, the heating element 144 can be a cylindrical spring-shaped heating wire or a cylindrical heating net, and the oil guide element 142 is wrapped around the heating element 144, and the whole is formed into a cylindrical shape and inserted into the cylindrical separation sleeve 146. Of course, other embodiments can also be ceramic cores or others.

[0034] In this embodiment, the piston assembly 182 includes a piston valve 1822, a piston frame 1824 and a transmission rod 1826. The piston valve 1822 is sleeved on the separation sleeve 146. One end of the piston valve 1822 and the transmission rod 1826 are both fixed to the piston frame 1824, and the other end of the transmission rod 1826 is in transmission connection with the power unit. After the power unit is energized to generate power, the power is transmitted to the transmission rod 1826. The transmission rod 1826 drives the piston frame 1824 and the piston valve 1822 to perform piston movement in the smoke separation sleeve 146, which can cover or expose the oil guide hole 1462 on the wall of the separation sleeve 146, thereby controlling the oil storage chamber 122 to be connected or disconnected from 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 is connected to the oil guide element 142 through the oil guide hole 1462. Figure 1 When the electronic cigarette is not needed, the piston valve 1822 is controlled to block the oil guide hole 1462, so that the oil storage chamber 122 is separated from the oil guide element 142, as shown in FIG. 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 packaging shell. The reduction gear is connected to the motor and the output shaft 1842 respectively, and the motor, the output shaft 1842 and the reduction gear are all arranged in the packaging shell. One end of the output shaft 1842 extends out of the packaging shell, and the output shaft 1842 is connected to the transmission rod 1826. When the motor is working, the power is transmitted to the output shaft 1842 through the reduction gear, and the output shaft 1842 drives the transmission rod 1826 to move, which can increase the stability and reliability of the transmission, and there is no need to manually apply external force, so that the piston assembly 182 can be moved evenly each time, which can avoid the problems of movement obstruction caused by uneven force, deformation affecting the sealing performance, and oil output stability and accuracy being affected, thereby improving the performance and service life, and also improving the user's suction experience. Among them, the motor is preferably a stepper motor.

[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, and the external thread is engaged with the internal thread, 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 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 1822 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 1826 can also be provided with an internal thread, and the output shaft 1842 can be provided with an external thread, and the external thread is engaged with the internal thread.

[0037] In this embodiment, a first mounting groove 1464 and an O-ring 1466 are provided on the outer wall of the separation sleeve 146. The first mounting groove 1464 is provided between the oil guide hole 1462 and the nozzle end of the shell 12, and the top of the first mounting groove 1464 protrudes from the outer wall of the separation sleeve 146. The O-ring 1466 is interference-fitted in the first mounting groove 1464. The O-ring 1466 is interference-fitted against the inner wall of the piston valve 1822, and an openable and closable smoke oil reserve chamber 1468 is formed between the outer wall of the separation sleeve 146 and the inner wall of the piston valve 1822 through a gap. The arrangement and coordination of the first mounting groove 1464 and the O-ring 1466, on the one hand, can ensure that the inner wall of the piston valve 1822 and the outer wall of the separation sleeve 146 can only be communicated through the oil guide hole 1462, and the sealing effect will not be poor due to oil leakage between the inner wall of the piston valve 1822 and the outer wall of the separation sleeve 146, resulting in failure to achieve the expected complete isolation when the oil storage chamber 122 and the oil guide element 142 need to be isolated; on the other hand, a smoke oil standby chamber 1468 that can accommodate a small amount of smoke oil can be formed between the inner wall of the piston valve 1822 and the outer wall of the separation sleeve 146. After the piston valve 1822 completely isolates the oil storage chamber 122, the smoke oil standby chamber 1468 can store a small amount of smoke oil, and can provide the required smoke oil to the oil guide element 142 when the electric piston valve 18 is just started and the oil supply does not meet the demand, thereby avoiding dry burning or burning of the oil guide element 142 due to insufficient oil supply, thereby improving the smoking taste and the service life of the atomizer 10.

[0038] See also Figure 3 In this embodiment, the piston rack 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 rack 1824 is embedded in the second mounting groove 1828. The arrangement of the piston rack 1824 or the piston valve 1822 embedded in the second mounting groove 1828 can make the connection between the piston valve 1822 and the piston rack 1824 more stable, and the piston rack 1824 will not loosen or even fall off when driving the piston valve 1822 to move, thereby ensuring the stability of the piston assembly 182.

[0039] See also Figure 2In this embodiment, the atomizer 10 is provided with a 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 separation 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 the two sides of the sealing silicone 19 are in contact with the base 16 and the separation sleeve 146 respectively. On the one hand, the gap between the base 16 and the separation sleeve 146 can be sealed, further ensuring the sealing performance of the oil storage chamber 122 and preventing the leakage of smoke oil; on the other hand, in addition to the part embedded in the third mounting groove 162, the sealing silicone 19 is also provided with a convex ear laid along the bottom of the oil storage chamber 122. When the piston valve 1822 separates the oil storage chamber 122 and the oil guide element 142, the lower end of the piston valve 1822 contacts the convex ear of the sealing silicone 19, which strengthens the sealing effect during the separation, that is, no smoke oil will pass through the piston valve 1822 during the separation.

[0040] See also 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 is connected to the output shaft 1842. The sealing silicone 19 and the transmission rod 1826 have an interference fit, and the transmission rod 1826 and the base 16 have a clearance fit; the piston valve 1822 and the separation sleeve 146 have a clearance fit, and the sealing silicone 19 and the base 16 and the separation sleeve 146 have an interference fit. The transmission rod 1826 and the base 16 have a clearance fit. Since the base 16 is a hard material, the clearance fit can avoid the wear of the base 16 during the movement of the transmission rod 1826, and can also avoid the base 16 affecting the movement of the transmission rod 1826; the piston valve 1822 and the separation sleeve 146 have a clearance fit, which can also avoid the wear between the piston valve 1822 and the separation sleeve 146 and the influence on the piston movement of the piston valve 1822. The interference fit of other parts is the fit of hard materials and soft materials. The interference fit can ensure good sealing performance while not affecting the movement of the transmission rod 1826 and the piston valve 1822. The piston frame 1824 is provided with a fourth mounting groove, the non-threaded end of the transmission rod 1826 is inserted into the fourth mounting groove, and the transmission rod 1826 and the fourth mounting groove are interference fit. Of course, the sealing silica gel 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 provided with a micro control 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 energize the circuit, that is, the pneumatic switch triggers the main control board to be energized, and the micro control unit sends a command to the motor control module to drive the motor to start, drive the piston assembly 182 to move, and the piston assembly 182 drives the movement of the piston assembly 182 according to the opening and closing of the pneumatic switch, thereby controlling the opening and closing of the oil storage chamber 122 and the oil guide hole 1462. That is, when the user sucks, the electric piston valve 18 is automatically started, and the power unit drives the piston assembly 182 to move to the upper dead center, so that the oil guide hole 1462 is connected to the oil storage chamber 122 and the oil guide element 142; when the suction stops, the power unit drives the piston assembly 182 to move to the lower dead center, so that the oil storage chamber 122 and the oil guide element 142 are separated; the oil storage chamber 122 and the oil guide element 142 are automatically separated according to the suction, which is convenient to use, safe and reliable.

[0042] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.
