Description

Electronic cigarettes with high sensitivity Technical Field

[0001] The present invention relates to the technical field of electronic atomization, and more particularly, to an electronic cigarette with high sensitivity. Background Art

[0002] Existing electronic cigarettes generally include a battery assembly and an atomizer assembly. The battery assembly is equipped with a battery and a control circuit for supplying power to the electronic cigarette. The atomizer assembly includes a heating unit. When the heating unit is powered on, it can atomize the solution to be atomized, namely the atomizing liquid, into vapor mist, aerosol or electronic cigarette smoke for the user to inhale. The atomized liquid includes tobacco liquid, medicinal liquid, herbal essence, etc.

[0003] In existing electronic cigarettes, the airflow sensor is generally installed in the battery assembly and shares an air intake channel with the smoke channel. The battery assembly is generally far away from the suction port, so the air intake encounters greater resistance. The air intake generated by the user's smoking takes some time to trigger the airflow sensor. As a result, the airflow generated by the user's smoking cannot be instantly sensed, and the heating element is powered on and started more slowly, making the electronic cigarette less sensitive.

Modes for Carrying Out the Invention

[0033] The present invention will be described in detail below with reference to the accompanying drawings. Example 1:

[0034] As shown in Figures 1 and 2, the highly sensitive electronic cigarette according to an embodiment of the present invention comprises a mouthpiece 1, an outer shell 2, an atomizer assembly, and a battery assembly. The atomizer assembly and battery assembly are respectively located inside the outer shell, on the left and right sides. The outer shell 2 comprises a front shell 21 and a rear shell 22. The rear shell 22 is box-shaped, and the atomizer assembly and battery assembly are located within the rear shell 22. The front shell 21 is mounted on the rear shell 22. In other embodiments, the atomizer assembly and battery assembly may also be connected vertically.

[0035] The atomizer assembly includes a liquid storage cup 4 for storing atomized liquid and an atomizer core 6 for heating and evaporating the atomized liquid. The battery assembly includes a battery 7 for providing power to the atomizer core 6 and a PCB control board 8. The mouthpiece 1 is located at one end of the outer shell and is connected to the atomizer assembly. The mouthpiece 1 is provided with an airflow sensing channel 10 and an airflow sensor 3. The airflow sensor 3 is located in the airflow sensing channel 10. When airflow is generated in the airflow sensing channel 10, the airflow sensor 3 can be triggered by the airflow. The airflow sensor 3 can also be a microphone or an air pressure sensor, which can be used to detect the inhalation airflow or inhalation negative pressure generated by the inhalation action. When the inhalation action is detected, the airflow sensor 3 is triggered to start the electronic cigarette to power on. The airflow sensor 3 is located in the mouthpiece 1, which can minimize the distance between the airflow sensor 3 and the mouthpiece 110. This can more quickly sense the airflow generated by the user when smoking, trigger the airflow sensor 3 more quickly, make the electronic cigarette more sensitive, and maximize the sensitivity of the electronic cigarette product. In addition, the airflow sensing channel 10 is provided separately from the electronic cigarette smoke channel, so as to avoid the problem that the airflow sensor cannot work due to the excessive amount of condensation in the smoke channel, which may cause blockage and further make the electronic cigarette inoperable.

[0036] As shown in Figures 1 to 4, the nozzle portion 1 includes a nozzle shell 11 and a nozzle bottom plug 12. The upper end of the nozzle portion 1, that is, the upper end of the nozzle shell 11, is provided with a suction port 110. The nozzle bottom plug 12 is sleeved on the inner bottom end of the nozzle shell 11, and the bottom of the nozzle bottom plug 12 is connected to the upper end of the liquid storage cup 4. The airflow sensing channel 10 is provided in the nozzle bottom plug 12 through which it is connected from top to bottom. The through-hole here is not limited to a vertical through-hole, but may also have a certain inclination or curvature or meander upward. The airflow sensing channel 10 is provided with a accommodating cavity 120, and the airflow sensor 3 is provided in the accommodating cavity 120. When the inhaled airflow passes through the airflow sensor 3 in the airflow sensing channel 10, the airflow sensor 3 can be triggered. The bottom of the accommodating cavity 120 is connected to the cavity where the battery assembly is located, that is, the lower section of the airflow sensing channel 10 is connected to the cavity where the battery assembly is located.

[0037] The outlet of the airflow sensing channel 10 on the nozzle bottom plug 12 extends upward and is provided with an outlet pipe 123. The outlet pipe 123 protrudes from the upper plane of the nozzle bottom plug 12, which can prevent condensation generated on the inner wall of the nozzle part 1 from dripping onto the upper plane of the nozzle bottom plug 12 and then flowing back into the airflow sensing channel 10, thereby preventing the condensation from corroding and damaging the airflow sensor 3 so that it cannot work normally.

[0038] The bottom plug 12 of the nozzle is further provided with a smoke outlet 121 for sucking smoke generated by the atomization core 6 into the nozzle portion 1 .

[0039] A first liquid filling port 122 for filling atomized liquid is also provided on the bottom plug 12 of the suction nozzle. A plunger 111 is provided on the inner bottom of the suction nozzle shell 11 and is inserted into and seals the first liquid filling port 122. The first liquid filling port 122 is connected to a second liquid filling port 414 provided at the upper end of the liquid storage cup 4. The bottom of the first liquid filling port 122 abuts against the upper plane of the second liquid filling port 414, so that the two can be sealed and connected.

[0040] The nozzle bottom plug 12 can be made of a soft material such as a silicone material, so that it has sealing properties when connected to the nozzle shell 11 and the upper end of the liquid storage cup 4.

[0041] As shown in Figures 5 and 6, the upper end of the liquid storage cup 4 is provided with an upward inner wall 411, and the outer side of the inner wall 411 is also provided with an outer wall 412. The nozzle bottom plug 12 is sleeved on the inner wall of the inner wall 411, and the lower wall of the nozzle shell 1 is sleeved between the inner wall 411 and the outer wall 412. The inner wall 411 and the outer wall 412 are provided with a notch 413 on the side corresponding to the airflow sensor 3 so that the lower section of the airflow sensing channel 10, that is, the horizontal section, can pass through.

[0042] As shown in Figures 2, 5-8, the atomizer assembly also includes an atomizer tube 5, within which an atomizer core 6 is disposed. The upper end of the liquid storage cup 4 is provided with an upper transverse wall 41 and a cup bottom cover 42. The cup bottom cover 42 seals the bottom opening of the liquid storage cup 4. An annular groove 421 is provided on the outer wall of the cup bottom cover 42, which is provided with a sealing ring 422. The ends of the atomizer tube 5 extend through the upper transverse wall 41 and the cup bottom cover 42 of the liquid storage cup 4, respectively. The inner wall of the liquid storage cup 4, the outer wall of the atomizer tube 5, and the cup bottom cover 42 enclose a liquid storage chamber 40.

[0043] The upper horizontal wall 41 of the liquid storage cup has a first through hole 410, into which the upper end of the atomizer tube 5 is inserted. The bottom cover 42 of the cup has a second through hole 420, into which the lower end of the atomizer tube 5 is inserted. In this embodiment, the upper end of the atomizer tube 5 is also inserted into the smoke outlet 121 of the bottom plug 12 of the nozzle.

[0044] The inner and outer diameters of the upper portion of the atomizer tube 5 are smaller than those of the lower portion, respectively, so that a larger atomizer core 6 can be installed in the lower portion of the atomizer tube 5. The smaller upper portion of the atomizer tube 5 allows the liquid storage chamber 40 to have more space to store more atomized liquid. In this embodiment, the atomizer core 6 is a tubular atomizer core 6 and is sleeved within the lower portion of the atomizer tube 5. A liquid inlet hole 51 is provided in the wall of the atomizer tube 5 located at the tubular atomizer core 6. This allows the atomized liquid in the liquid storage chamber 40 to pass through the liquid inlet hole 51 and be absorbed by the tubular atomizer core 6.

[0045] As shown in Figures 1, 2, and 8, the tubular atomizer core 6 comprises a tubular absorbing liquid 61, a heating element (not shown), and an electrode pin 62. The heating element is located within the tubular absorbing liquid 61. After absorbing the atomized liquid, the tubular absorbing liquid 61 can penetrate and conduct the atomized liquid to the surface of the heating element. When the heating element is energized, the atomized liquid is heated and evaporated into aerosol. The aerosol is emitted from the inner tube hole of the tubular absorbing liquid 61 and flows upward through the inner tube hole of the atomizer tube 5. The tubular absorbing liquid 61 is composed of a nanoporous ceramic material. After the atomized liquid passes through this nanoporous material, the evaporated aerosol particles are finer and the smoking experience is better. An insulating ring 52 is also connected to the bottom of the tubular atomizer core 6 within the atomizer tube 5. The electrode pin 62 of the tubular atomizer core 6 is located within the insulating ring 52. The atomizer tube 5 is generally made of metal. The insulating ring 52 prevents the electrode pin 62 from contacting the atomizer tube 5 and causing a short circuit.

[0046] As shown in Figure 1, the front housing 21 is provided with a button 211 and a transparent lens 212. The button 211 is connected to a key switch 81 on the PCB control board 8. Pressing the button 211 controls the key switch 81. In this embodiment, pressing the button 211 adjusts the operating power of the atomizer core 6 and, by extension, the atomization volume, to meet customer needs for vapor volume. A display 82 is provided on the PCB control board 8 below the transparent lens 212. The display 82 displays parameters such as the remaining battery charge, the remaining atomizer liquid level, and the operating power of the atomizer core. The bottom of the rear housing 22 also includes a housing air inlet hole 220 and a through-hole 221 for a USB charging port. The USB charging port 83 is mounted on the PCB control board 8 and extends from the through-hole 221.

[0047] As shown in Figures 1, 2, and 9, the atomizer assembly and battery assembly are located on the left and right sides of the housing, respectively. A silicone base 9 is provided between the lower portion of the cup bottom cover 42 and the inner bottom of the outer housing. The silicone base 9 is provided with a base air inlet hole 90 that communicates with the bottom of the atomizer tube 5.

[0048] The working principle of the electronic cigarette with high sensitivity in this embodiment is as follows: As shown in FIG2, when the user inhales from the suction port 110, a negative pressure is generated inside the suction mouth. In the direction indicated by the continuous solid arrow a in the figure, the external air enters from the air inlet hole 220 of the shell, passes through the air inlet hole 90 of the base and the bottom of the atomizer tube 5 and enters the inner tube hole of the tubular atomizer core 6. At the same time, in the direction indicated by the continuous solid arrow b in the figure, the external air enters from the air inlet hole 220 of the shell, passes through the cavity where the battery assembly is located and enters the air flow sensing channel 1. 0. When passing through the airflow sensor 3, the airflow sensor 3 is triggered. After the airflow sensor 3 is triggered, the PCB control board is used to start the heating element of the tubular atomizing core 6, and the heating element can heat the atomized liquid in the tubular absorbing liquid 61 and evaporate it into smoke. The smoke can be emitted from the inner tube hole of the tubular absorbing liquid 61. At this time, driven by the external gas entering the tubular atomizing core, the smoke flows upward from the inner tube hole of the atomizing tube 5 and is sucked into the user's mouth through the smoke outlet 121 and the suction port 110 on the bottom plug 12 of the suction nozzle. While the heating element is working and the atomized liquid is evaporated into smoke, the atomized liquid in the liquid storage chamber 40 flows downward in the direction indicated by the continuous hollow arrow c in the figure, enters the liquid inlet through-hole 51 of the atomizing tube 5, and is absorbed by the tubular absorbing liquid 61. In this way, the heating element can be continuously replenished for atomization. Industrial Applicability
