Description

Technical Field

[0001] This utility model belongs to the field of electronic cigarette technology, specifically relating to a leak-proof, visible e-liquid electronic cigarette. Background Technology

[0002] The health hazards of smoking have received widespread attention, yet there are still hundreds of millions of smokers worldwide, and this number continues to grow, demanding serious attention from all sectors. Banning smoking in public places to improve the environment has become a consensus. As a result, e-cigarettes have emerged. They do not contain harmful tar components or carcinogens; they do not burn, thus avoiding the various harmful chemicals produced by combustion; they do not cause secondhand smoke or environmental pollution; they do not require fire, eliminating the fire hazard; and they can be used to gradually quit smoking through a four-step smoking cessation method.

[0003] However, in traditional e-cigarette cartridges, the e-liquid supply to the atomizing component is typically achieved through a simple sealing structure or natural oil inlet, lacking an active and controllable oil-blocking mechanism. When the device is subjected to external impact, tilted placement, or prolonged inactivity, e-liquid can easily seep into the atomizing component through the inlet, resulting in e-liquid waste, potential atomizer coil failure due to soaking, short circuits in the internal circuitry, and even e-liquid leakage from the mouthpiece, staining clothing and severely impacting the user experience. Therefore, developing a reliable leak-proof e-cigarette device has become an urgent need for the industry. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a leak-proof, visually-enabled e-liquid electronic cigarette. By adding an oil-blocking unit, the e-liquid entering the atomizing component can be controlled and adjusted, effectively preventing oil leakage during transportation and use, and improving the user experience.

[0005] The specific technical solution adopted in this utility model is as follows:

[0006] A leak-proof, visible e-liquid electronic cigarette includes a housing, a cartridge unit, and a control unit located within the housing. The cartridge unit includes an oil cup and an atomizing component. E-liquid in the oil cup enters the atomizing component through an oil inlet and is atomized. An oil-blocking unit is added between the oil cup and the atomizing component. The oil-blocking unit includes an oil-blocking cap and a driving component. The driving component is energized by the control unit and reciprocates. The oil-blocking cap has the freedom to block or move away from the oil inlet through the driving component.

[0007] The drive assembly includes a one-way valve coil assembly in the shape of a circular groove, and a spring and a magnet located inside the one-way valve coil assembly. The oil-blocking cap is fixedly connected to the magnet, and the magnet is connected to the bottom of the groove of the one-way valve coil assembly by means of the spring. The one-way valve coil assembly forms magnetism by means of the power supply of the control unit and attracts the magnet to compress the spring. The oil-blocking cap forms a reciprocating movement by means of the compression and reset of the spring.

[0008] The drive assembly also includes a guide sleeve and a cap fixed to one end of the guide sleeve. The guide sleeve is fitted into the slot of the one-way valve coil assembly and forms a sliding fit. The magnet is assembled inside the guide sleeve. The two ends of the guide sleeve are sealed by an oil-blocking cap and a cap, respectively.

[0009] The oil-blocking cap is also provided with oil-blocking and sealing silicone on its periphery.

[0010] The control unit includes a control board and a battery cell connected to the control board for power supply. The coil of the one-way valve coil assembly is connected to the battery cell via the control board. The control board is provided with button silicone.

[0011] The atomizing assembly includes an atomizing tube, an atomizing core, and a heating wire holder. The atomizing core is wrapped with oil storage cotton. The input end of the atomizing core is connected to the oil inlet, and the output end of the atomizing core is connected to the atomizing tube via the heating wire holder.

[0012] The housing is also provided with an air regulating channel. One end of the air regulating channel is connected to the atomizing tube, and the other end of the air regulating channel is connected to the outside through the air regulating silicone and the air regulating switch. The air regulating silicone is provided with condensation cotton. Air is drawn into the air regulating channel in one direction through the air regulating silicone and mixes with the atomized e-liquid in the atomizing tube.

[0013] A transparent lens is provided on the housing, and the content displayed on the digital tube on the control panel can be seen with the help of the transparent lens.

[0014] The beneficial effects of this utility model are:

[0015] 1. In this utility model, the oil-blocking unit is added to prevent oil leakage. The e-liquid is stored in the oil cup. Under normal conditions, the oil-blocking cap tightly seals the oil inlet hole under the pushing action of the drive component. The e-liquid cannot enter the atomizing component due to the sealing effect of the oil-blocking unit.

[0016] When the user continues to inhale until the control board's timer reaches the set number of seconds, the control board will control the drive component to move the oil-blocking cap away from the oil inlet, and only then will the e-liquid enter the atomizing component.

[0017] After a fixed number of seconds have elapsed since the oil inlet is opened, the control board resets the drive assembly, drives the oil blocking cap to re-seal the oil inlet, and stops the oil supply. At this point, the suction time is reset to zero and recalculated.

[0018] The above structure effectively prevents oil leakage during product transportation and use. The entry of e-liquid into the atomizing component is adjustable and controllable, avoiding the inhalation of e-liquid and providing a better user experience.

[0019] 2. The electronic cigarette shell of this utility model has a visual design, which makes it convenient for users to observe the power and oil level displayed on the digital tube of the control board through the transparent lens, so as to replenish the e-liquid or charge it in time. At the same time, the oil cup itself is made of transparent material, so the e-liquid can be observed through the oil cup. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0025] Specific embodiments, such as Figure 1-3 As shown, this utility model provides a leak-proof, visible e-liquid electronic cigarette, including a housing 1 and a cartridge unit 2 and a control unit 3 located inside the housing 1. The cartridge unit 2 includes an oil cup 201 and an atomizing component. The e-liquid in the oil cup 201 enters the atomizing component through the oil inlet 5 and is atomized. An oil-blocking unit 4 is added between the oil cup 201 and the atomizing component. The oil-blocking unit 4 includes an oil-blocking cap 401 and a driving component. The driving component is powered by the control unit 3 and reciprocates. The oil-blocking cap 401 has the freedom to block and move away from the oil inlet 5 with the help of the driving component.

[0026] In traditional e-cigarette cartridges, the e-liquid cup 201 and the atomizing component are typically supplied with e-liquid only through a simple sealing structure or natural oil inlet, lacking an active and controllable oil-blocking mechanism. When the device is subjected to external impact, tilted placement, or left idle for an extended period, e-liquid can easily seep into the atomizing component through the oil inlet 5. This not only wastes e-liquid but may also cause the atomizing core 203 to become immersed and malfunction, short-circuit the internal circuitry of the device, or even cause e-liquid to leak from the mouthpiece and stain clothing, severely impacting the user experience.

[0027] Therefore, in this utility model, the oil-blocking unit 4 is added to prevent oil leakage. The e-liquid is stored in the oil cup 201. Under normal conditions (i.e. when not inhaling), the oil-blocking cap 401 tightly seals the oil inlet 5 under the pushing action of the drive component. The e-liquid cannot enter the atomizing component due to the sealing effect of the oil-blocking unit 4.

[0028] When the user continues to inhale and the timer on the control board 301 reaches the set number of seconds, the control board 301 will control the drive component to move the oil-blocking cap 401 away from the oil inlet 5, and only then will the e-liquid enter the atomizing component.

[0029] After the oil inlet 5 is opened, and a fixed number of seconds have elapsed, the control board 301 controls the drive assembly to reset, and the drive oil cap 401 re-seals the oil inlet 5, stopping the oil supply. At this time, the suction time is reset to zero and recalculated.

[0030] The above structure effectively prevents oil leakage during product transportation and use. The entry of e-liquid into the atomizer core 203 component is adjustable and controllable, avoiding the inhalation of e-liquid and providing a better user experience.

[0031] The drive assembly includes a one-way valve coil assembly 402 in the shape of a circular groove, and a spring 403 and a magnet 404 located inside the one-way valve coil assembly 402. The oil-blocking cap 401 is fixedly connected to the magnet 404. The magnet 404 is connected to the bottom of the groove of the one-way valve coil assembly 402 by means of the spring 403. The one-way valve coil assembly 402 forms magnetism by means of the power supply of the control unit 3 and attracts the magnet 404 to compress the spring 403. The oil-blocking cap 401 reciprocates by means of the compression and reset of the spring 403.

[0032] The one-way valve coil assembly 402 includes a circular groove-shaped insulating frame and an electromagnetic coil wound on the surface of the insulating frame. The one-way valve coil assembly 402 is generally circular groove-shaped.

[0033] The specific working principle of the drive component is as follows: Under normal conditions, the spring 403 will push against the oil-blocking cap 401 and the magnet 404. Under the action of the spring 403, the oil-blocking cap 401 will close the oil inlet hole 5. When the user continues to inhale for a set number of seconds, the control board 301 will energize the one-way valve coil assembly 402. After the coil has current, it will generate magnetism and attract the magnet 404. Under the action of electromagnetic attraction, the magnet 404 will squeeze the spring 403 and move the oil-blocking cap 401 towards the bottom of the groove of the one-way valve coil assembly 402. At this time, the oil-blocking cap 401 will leave the oil inlet hole 5, and the e-liquid can enter the atomizing component.

[0034] The drive assembly also includes a guide sleeve 405 and a cap 406 fixed to one end of the guide sleeve 405. The guide sleeve 405 is fitted into the slot of the one-way valve coil assembly 402 and forms a sliding fit. The magnet 404 is assembled inside the guide sleeve 405. The two ends of the guide sleeve 405 are sealed by an oil-blocking cap 401 and a cap 406, respectively.

[0035] The guide sleeve 405 provides a rigid guide track for the movement of the magnet 404 and the oil blocking cap 401, avoiding misalignment between the oil blocking cap 401 and the oil inlet 5 due to offset during movement, which could lead to incomplete sealing. The pipe cap 406 and the oil blocking cap 401 together seal both ends of the guide sleeve 405, confining the magnet 404 inside the sleeve, preventing it from directly rubbing against the insulating frame, reducing mechanical wear, and maintaining long-term working accuracy.

[0036] The oil-blocking cap 401 is also provided with an oil-blocking and sealing silicone 407 on its periphery.

[0037] Oil-blocking sealing silicone 407 is used to seal the gap between oil-blocking unit 4 and bracket 207.

[0038] The control unit 3 includes a control board 301 and a battery cell 302 that is powered and connected to the control board 301. The coil of the one-way valve coil assembly 402 is connected to the battery cell 302 via the control board 301. The control board 301 is provided with button silicone 303.

[0039] The control board 301 presets the trigger conditions (suction time) of the oil blocking unit 4 through programming and outputs a current signal to the one-way valve coil assembly 402; the battery cell 302 provides a stable power supply to ensure reliable coil magnetic force; the button silicone 303 matches the button position on the control board 301 to assist in pressing the button.

[0040] The atomizing assembly includes an atomizing tube 202, an atomizing core 203, and a heating wire holder 204. The atomizing core 203 is wrapped with an oil storage cotton 205. The input end of the atomizing core 203 is connected to the oil inlet 5, and the output end of the atomizing core 203 is connected to the atomizing tube 202 via the heating wire holder 204.

[0041] The oil-retaining cotton 205 on the outside of the atomizing core 203 uses capillary action to evenly absorb and transport the e-liquid flowing into the oil inlet 5 to the surface of the atomizing core 203, ensuring that the heating coil is always moist but not excessive, avoiding the burnt taste caused by dry burning without oil, and preventing the problem of insufficient atomization due to excessive e-liquid, which affects the greasy taste of inhalation.

[0042] The housing 1 is also provided with an air regulating channel. One end of the air regulating channel is connected to the atomizing tube 202, and the other end of the air regulating channel is connected to the outside through the air regulating silicone 6 and the air regulating switch 7. The air regulating silicone 6 is provided with condensation cotton 206. Air is drawn into the air regulating channel in one direction through the air regulating silicone 6 and mixes with the atomized e-liquid in the atomizing tube 202.

[0043] The condensation cotton 206 inside the regulating silicone 6 prevents condensate from flowing onto the regulating switch 7 and leaking out of the e-cigarette. The regulating silicone 6 ensures the airtightness of the regulating channel, allowing outside air to enter only through the path controlled by the regulating switch 7. Users can control the air intake by adjusting the switch opening; a larger air intake results in a more diluted vapor, while a smaller air intake results in a denser vapor, allowing for free adjustment of the flavor.

[0044] In addition, the cartridge unit 2 also includes an oil-sealing silicone 208, an atomizing sealing silicone 209, and a bracket 207 for fixing the various parts.

[0045] A transparent lens 8 is provided on the housing 1, and the content displayed on the digital tube on the control board 301 is visible with the help of the transparent lens 8.

[0046] The transparent lens 8 is a semi-transparent black lens, which allows users to easily observe the power and oil levels displayed on the digital tube of the control panel 301 through the transparent lens 8, so as to replenish the e-liquid or charge it in time. At the same time, the oil cup 201 itself is made of transparent material, so the e-liquid can be observed through the oil cup 201.

[0047] When installing an electronic cigarette, first assemble each unit:

[0048] After assembling the oil-sealing silicone 208, oil-collecting cotton 205, atomizing core 203, atomizing tube 202, and heating wire holder 204, insert them into the bracket 207. Then, install the atomizing sealing silicone 209 and insert it into the oil cup 201. Finally, install the condensation cotton 206 and the gas-adjusting silicone 6. The assembly of the e-cigarette unit 2 is completed as described above.

[0049] Oil blocking unit 4: After the oil blocking cap 401, magnet 404, guide sleeve 405, and tube cover 406 are assembled, they are assembled together with oil blocking sealing silicone 407 and spring 403 into the insulating frame of the one-way valve coil assembly 402. The oil blocking unit 4 is assembled as described above.

[0050] Other parts: First, fix the cartridge unit 2 and the oil blocking unit 4, then install the control board 301, then install the gas adjustment switch 7, then install the bottom shell 101, weld the battery cell 302, cover the top shell 102, install the button silicone 303 and the transparent lens 8, and the entire electronic cigarette is assembled.
