Description

Technical Field

[0001] The present invention relates to the technical field of electronic cigarettes, and particularly relates to an electronic cigarette with a check valve kit and a using method thereof. Background Art

[0002] With the continuous improvement of people's pursuit of health and quality of life, traditional tobacco products have gradually been questioned due to their harmful components and potential threats to health. As a new alternative, electronic cigarettes have gradually gained the favor of the majority of consumers due to their relatively low health risks and diverse flavor choices. However, there are a wide variety of electronic cigarette products on the market, and the quality is uneven. Many products still have many deficiencies in terms of structural design, function realization, and user experience.

[0003] First, there is a lack of an effective water filtration system, which cannot achieve the functions of humidifying and cooling the smoke, resulting in a dry and irritating taste. Second, the problem of condensate backflow is common. When the e-liquid is not atomized sufficiently, liquid particles are likely to enter the user's mouth along with the airflow. Third, electronic cigarettes that attempt to add a water cooling system often face the risk of seal failure. Once reverse flow occurs in the water storage cavity, serious faults such as short circuits and atomization core damage will be caused. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to propose an electronic cigarette with a check valve kit.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An electronic cigarette with a check valve kit, comprising:

[0007] A housing, inside which a mouthpiece, a water cup chamber, and a bottom cover are sequentially arranged along the axial direction;

[0008] A valve, sealingly connected between the mouthpiece and the water cup chamber. The two ends of the valve are in a conical structure and are in interference fit with the mouthpiece and the water cup chamber respectively, for preventing condensate from flowing back to the mouthpiece;

[0009] A check valve kit, including a smoke guide tube, a one-way flow valve silicone, and a smoke outlet tube. The smoke guide tube is fixedly arranged in the water cup chamber. The one-way flow valve silicone is embedded in the smoke guide tube to form a one-way air flow channel. The smoke outlet tube penetrates through the one-way flow valve silicone and is coaxially arranged with the smoke guide tube;

[0010] A limit seat, fixedly installed in the housing and abutted against the end of the water cup chamber. An oil storage chamber is sleeved outside the limit seat, and an oil storage cotton and a heating core are arranged in the oil storage chamber;

[0011] The regulating valve is disposed inside the bottom cover and includes a fixed disk and a rotating disk arranged coaxially. The fixed disk is provided with a first exhaust hole, and the rotating disk is provided with a second exhaust hole corresponding to the first exhaust hole. The overlapping degree of the exhaust holes is adjusted by relative rotation.

[0012] Wherein, when the user inhales, the air flow enters the interior of the outer shell through the regulating valve. The heating core heats to generate smoke, which successively passes through the smoke outlet pipe, the one-way flow valve silicone and the valve and enters the mouthpiece. The one-way flow valve silicone prevents the smoke and water from flowing back.

[0013] As a further improvement of the above technical solution:

[0014] The connecting end of the mouthpiece and the water cup chamber is provided with a mutually matching stepped structure and is bonded and fixed through a connecting ring.

[0015] A plurality of first clamping blocks are circumferentially arranged at the end of the water cup chamber, and clamping grooves that are clamped and matched with the first clamping blocks are correspondingly arranged on the inner wall of the outer shell.

[0016] One end of the one-way flow valve silicone is in sealing contact with the inner wall of the water cup chamber, and one end of the smoke outlet pipe forms an axial seal with the limiting seat.

[0017] An installation hole is provided on the outer side of the outer shell, a lens is embedded in the installation hole, and a relief hole corresponding to the position of the power button is provided on the lens.

[0018] A torsion bar extending radially is integrally formed on the outer side of the rotating disk for manually adjusting the rotation angle of the rotating disk.

[0019] A connecting seat is further provided inside the outer shell, and a through hole communicating the oil storage chamber and the battery chamber is provided on the connecting seat.

[0020] A using method of an electronic cigarette with a check valve kit, which is applied to the above-mentioned electronic cigarette, includes the following steps:

[0021] S1. Inhalation trigger stage: When the user inhales, the air flow enters the air cavity through the regulating valve, the air flow sensor detects a negative pressure signal, and the PCB board starts the heating program;

[0022] S2. Heating and atomization stage: The storage battery supplies power to the heating core, and the temperature rises to 200 - 220 °C within 3 seconds to atomize the e-liquid in the oil storage cotton. The atomized smoke passes through the smoke outlet pipe and enters the smoke guiding pipe;

[0023] S3. Smoke delivery stage: The smoke enters the water cup chamber through the one-way flow valve silicone. During this process, the one-way valve prevents the water vapor from flowing back, and the smoke exchanges heat with the water in the water cup chamber to cool down;

[0024] S4. Inhaling stage: The cooled smoke enters the mouthpiece through the valve. The conical structure of the valve ensures the unidirectional flow of the smoke and prevents the liquid from flowing back;

[0025] S5, Airflow Regulation: By rotating the twisted strip, the overlapping degree of the first exhaust hole and the second exhaust hole is changed to accurately control the intake air volume (0.5 - 3 L / min) and achieve the suction resistance regulation.

[0026] Beneficial Effects: 1. Dual anti-backflow guarantee: Through the synergistic effect of the conical valve 7 and the one-way flow valve silicone 11, the conical valve adopts a 15° conical surface design and remains sealed under a pressure of 0.3 MPa. The one-way flow valve silicone forms a pressure-sensitive barrier and only opens when the negative pressure exceeds 0.01 MPa, which can completely block the reverse penetration of liquid.

[0027] 2. Intelligent gas-liquid separation: Realized by the axial layout of the water cup chamber 8 and the smoke guide tube 9: When the smoke passes through the water medium, the temperature drops from 200 °C to 45 - 50 °C, and the condensate is intercepted at the bottom of the water cup chamber. The separation efficiency reaches 99.2%, achieving the experience effect of water pipe smoking, which can moisten the taste and enhance the pleasure.

[0028] In the present invention, the stable connection of each component is achieved through the snap connection structure, and the conical valve design is adopted to effectively prevent the water in the water cup chamber from flowing back to the mouthpiece. At the same time, the use of the flow stop valve kit realizes the separation of oil and water, achieving the experience effect of water pipe smoking, which can moisten the taste and enhance the pleasure.
