Description

Technical Field

[0001] This invention relates to the field of electronic cigarette technology, specifically to a liquid inlet valve and an electronic cigarette. Background Technology

[0002] As a novel tobacco alternative, e-cigarettes have experienced rapid growth in the consumer electronics market in recent years. To prevent e-liquid leakage, ensure precise delivery, and improve flavor consistency, e-cigarettes typically employ a valve-based design to control the liquid inlet path.

[0003] Currently, common electronic control valves in the e-cigarette industry mainly include electromagnet-driven and micro-motor-driven solutions. However, both of these solutions have several shortcomings in practical applications. First, both electromagnet-driven and micro-motor-driven solutions generally suffer from complex configurations and a large number of components, including coils, magnetic cores, gears, transmission rods, and other precision parts, making assembly processes cumbersome. Second, these electronic control valves often generate noticeable noise during operation, affecting the user experience. More importantly, this inherent complexity not only directly increases manufacturing costs, but their relatively large mechanical structure also occupies valuable internal space, contradicting the growing trend of miniaturization and integration in consumer electronics.

The fixing block is provided with a shape memory alloy. The two ends of the shape memory alloy are respectively connected to the power supply circuit. The shape memory alloy is connected to the sealing plug. The shape memory alloy is configured to shrink and deform when energized. The shape memory alloy is used to pull the sealing plug to separate from the liquid outlet.

[0005] As a further improvement of the present invention, a rigid moving block is also included, which is disposed between the fixed block and the valve core.

[0014] On the other hand, the present invention also provides an electronic cigarette, including the above-mentioned liquid inlet valve, and further including a housing and an atomizing core. The liquid inlet valve is disposed inside the housing, and the atomizing core is used to heat and atomize the atomizing medium into an aerosol. The side wall of the atomizing core is provided with a liquid inlet hole, and the valve core is provided with a liquid inlet channel, which communicates with the liquid inlet hole.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0023] like Figures 1 to 7 As shown, an electronic cigarette includes a casing 1, which serves as the support and protective structure for the entire product. Inside the casing are a liquid inlet valve, a battery 2, and a control board 3. The battery 2 provides power to the entire electronic cigarette, while the control board 3 controls its various functions. The control board 3 integrates electronic components and corresponding circuit structures, enabling control of atomization heating and valve opening and closing. The battery 2 is electrically connected to the control board 3. When the user inhales, the control board 3 controls the battery 2 to supply power, thereby initiating the liquid inlet and atomization process. This electronic control method provides rapid response, enabling instant liquid supply and atomization, thus enhancing the user experience.

[0024] The liquid inlet valve includes a liquid reservoir 4, an atomizing core 5, a sealing cap 6, a valve core 7, a fixing block 8, a reset assembly, and a rigid moving block 9. The liquid reservoir 4 stores the atomizing medium, which is e-cigarette e-liquid. The liquid reservoir 4 has a cup-shaped structure with an internal oil storage chamber. The liquid reservoir 4 is made of a transparent material, such as transparent plastic or glass. Visible openings 101 are provided on the front and rear side walls of the outer casing 1 at positions corresponding to the liquid reservoir 4, allowing users to directly observe the remaining e-liquid level through the visible openings 101 and the transparent walls of the liquid reservoir 4, facilitating timely refilling.

[0025] The atomizing core 5 is located below the liquid reservoir 4 and is used to heat and atomize the atomizing medium into an aerosol. The atomizing core 5 is electrically connected to the control board 3 via wires. The control board 3 controls the operation of the atomizing core 5, thereby heating and atomizing the e-liquid. The atomizing core 5 has a columnar structure and contains a heating element and a wicking medium inside. A liquid inlet 51 is provided on the side wall of the atomizing core 5, penetrating the side wall to introduce e-liquid into the atomizing core 5 to contact the heating element. When the heating element is powered on, the e-liquid is heated and atomized into an aerosol for the user to inhale.

[0026] A sealing cap 6 is located at the open end of the liquid reservoir 4, and is sealed to the inner wall of the liquid reservoir 4. The outer edge of the sealing cap 6 fits tightly against the inner wall of the liquid reservoir 4, using an interference fit or a sealing ring to ensure that the e-liquid in the liquid reservoir 4 does not leak from the gap between the sealing cap 6 and the side wall of the liquid reservoir 4. The sealing cap 6 has an outlet hole 61, which penetrates both the upper and lower ends of the sealing cap 6 and is the necessary channel for e-liquid to flow from the liquid reservoir 4 to the atomizer core 5. The diameter of the outlet hole 61 determines the e-liquid flow rate, and its diameter can be designed according to actual atomization needs.

[0027] The valve core 7 is located on the side of the sealing cap 6 away from the reservoir cup 4, specifically below the sealing cap 6. The valve core 7 is sealed to the lower end face of the sealing cap 6, ensuring that e-liquid does not leak from the connection point during flow. The valve core 7 is made of elastic silicone material, which has good elasticity and flexibility, allowing it to deform elastically under external force and return to its original shape after the force is removed. Simultaneously, silicone material has excellent oil resistance and sealing performance, allowing it to be immersed in e-liquid for extended periods without swelling or performance degradation. A sealing plug 71 is integrally formed on the valve core 7, protruding upwards from the upper end face of the valve core 7 in a columnar or frustum-shaped structure. The sealing plug 71 is aligned with the outlet hole 61 on the sealing cap 6, meaning the central axis of the sealing plug 71 coincides with the central axis of the outlet hole 61. In its natural state, the sealing plug 71 rests against the periphery of the outlet hole 61, thereby sealing the outlet hole 61 and preventing the e-liquid in the reservoir cup 4 from flowing downwards.

[0028] The sealing plug 71 is integrally formed with a thin wall 72 around its perimeter. The thin wall 72 is located in the connection area between the root of the sealing plug 71 and the main body of the valve core 7, and has an annular thin wall structure. The thickness of the thin wall 72 is 0.2 mm to 0.5 mm. This thickness range ensures that the thin wall 72 has sufficient structural strength and is easy to undergo elastic deformation under stress. The wall thickness of the thin wall 72 is thinner than other parts of the valve core 7. This thin wall structure can preferentially undergo elastic deformation under stress, which plays a role in stress concentration and deformation buffering. The valve core 7 is also provided with a liquid inlet channel 73. One end of the liquid inlet channel 73 corresponds to the position of the liquid outlet hole 61 on the sealing cap 6, and the other end is connected to the liquid inlet hole 51 on the side wall of the atomizing core 5. When the sealing plug 71 is separated from the liquid outlet hole 61, the e-liquid in the reservoir cup 4 flows into the atomizing core 5 through the liquid outlet hole 61, the liquid inlet channel 73 and the liquid inlet hole 51 in sequence.

[0029] The fixing block 8 is located on the side of the valve core 7 away from the sealing cover 6, i.e., below the valve core 7. The fixing block 8 has a block-like structure and is made of a hard material, such as plastic or metal. A shape memory alloy 10 is provided on the fixing block 8. Both ends of the shape memory alloy 10 are electrically connected to the control board 3. Specifically, one end of the shape memory alloy 10 is connected to the positive terminal of the power supply circuit on the control board 3, and the other end is connected to the negative terminal of the power supply circuit on the control board 3. The shape memory alloy 10 is configured to shrink and deform when energized. That is, under the action of the energizing current, the temperature of the shape memory alloy 10 rises above the phase transformation temperature, undergoing a martensitic-to-austenitic phase transformation, thereby shortening the length of the alloy wire. The shape memory alloy 10 is connected to the sealing plug 71. When the shape memory alloy 10 shrinks when energized, it generates a downward pulling force, pulling the sealing plug 71 to overcome the elastic resistance of the thin wall 72 and the resistance of the reset assembly, moving it away from the sealing cover 6, thereby opening the liquid outlet 61. The shape memory alloy 10 has a long, rope-like structure with a diameter of 0.1 mm to 0.5 mm, preferably 0.1 mm to 0.25 mm. This fine filament structure makes the shape memory alloy 10 extremely compact, facilitating its arrangement within the limited internal space of an electronic cigarette. The small diameter also helps to accelerate the heating and cooling rates after energization, thereby improving the valve's response speed. The shape memory alloy 10 is a nickel-titanium shape memory alloy wire or a copper-based shape memory alloy wire; in other embodiments, any existing shape memory alloy material can also be used.

[0030] During operation, when the shape memory alloy 10 is energized and contracts to pull the sealing plug 71, the sealing plug 71 compresses the thin wall 72, causing it to elastically deform. The sealing plug 71 moves downwards within the allowable deformation of the thin wall 72, thus disengaging from the liquid outlet 61. At this time, the liquid outlet 61 connects with the liquid inlet channel 73. Under the influence of gravity, the e-liquid in the reservoir cup 4 flows from the liquid outlet 61 into the liquid inlet channel 73, and then through the liquid inlet 51 into the atomizer core 5, thus supplying e-liquid. When the shape memory alloy 10 is de-energized and returns to its original position, the thin wall 72, relying on its own elastic restoring force, assists the reset assembly in pushing the sealing plug 71 back to its original position, resealing the liquid outlet 61.

[0031] A rigid moving block 9 is disposed between the fixed block 8 and the valve core 7. The rigid moving block 9 has a block-like structure and is made of a rigid material, such as plastic or metal. The rigid moving block 9 has a connecting block 91 and a slot 92. The connecting block 91 protrudes upward from the upper end surface of the rigid moving block 9 and is fixedly connected to the sealing plug 71, realizing the linkage between the rigid moving block 9 and the sealing plug 71. The slots 92 are disposed on the left and right sides of the rigid moving block 9, and the middle part of the shape memory alloy 10 is engaged and fixed with the slot 92. In this embodiment, there are two shape memory alloys 10, and the middle parts of the two shape memory alloys 10 are respectively fitted onto the corresponding slots 92. By setting the rigid moving block 9, the tensile force of the shape memory alloy 10 can be evenly transmitted to the sealing plug 71, avoiding damage to the sealing plug 71 due to excessive local stress. At the same time, the rigid moving block 9 also provides a reliable connection structure for fixing the shape memory alloy 10.

[0032] The reset assembly is connected to the sealing plug 71 and is used to drive the sealing plug 71 to move closer to the sealing cap 6, so that the sealing plug 71 blocks the liquid outlet 61. The reset assembly includes a reset spring 11, which is disposed between the fixed block 8 and the rigid moving block 9. The two ends of the reset spring 11 abut against the fixed block 8 and the rigid moving block 9, respectively. In the natural state (i.e., when the shape memory alloy 10 is not energized), the reset spring 11 is in a preliminary compressed state, applying an upward thrust to the sealing plug 71, so that the sealing plug 71 always tends to move closer to the sealing cap 6, thereby maintaining the state in which the sealing plug 71 blocks the liquid outlet 61. When the shape memory alloy 10 is energized and contracts, its contraction force overcomes the elastic force of the reset spring 11, pulling the sealing plug 71 downward, pulling it away from the liquid outlet 61, and opening the liquid inlet passage; during the downward movement of the sealing plug 71, the reset spring 11 is further compressed. When the shape memory alloy 10 is de-energized, the contraction force disappears, the reset spring 11 releases elastic potential energy, and pushes the sealing plug 71 upward until the sealing plug 71 re-blocks the liquid outlet 61 and closes the liquid inlet passage.

[0033] To improve the sealing performance between the sealing plug 71 and the sealing cap 6, an annular protrusion 74 is provided on the upper end face of the sealing plug 71. The annular protrusion 74 is arranged along the periphery of the upper end face of the sealing plug 71, forming a ring-shaped protrusion structure, and is distributed around the liquid outlet 61. When the return spring 11 drives the sealing plug 71 to move closer to the sealing cap 6, the lower end face of the sealing cap 6 will squeeze the annular protrusion 74, causing the annular protrusion 74 to undergo elastic deformation and form a tight seal with the lower end face of the sealing cap 6. The annular protrusion 74 is equivalent to an integrally formed sealing ring, which can significantly improve the connection and sealing performance between the sealing plug 71 and the sealing cap 6, ensuring that the liquid outlet 61 is completely blocked and the e-liquid will not leak when the liquid inlet valve is closed.

[0034] The bottom of the outer casing 1 is equipped with a charging connector 12 and a gas flow control switch 13. The charging connector 12 is electrically connected to the control board 3 for charging the battery 2. The gas flow control switch 13 is slidably limited to the outer casing 1 and has multiple air inlets 131. Inside the outer casing 1 is a mounting bracket 14 with an air intake channel 141. One end of the air intake channel 141 is connected to the atomizing core 5, and the other end extends to the gas flow control switch 13. The gas flow control switch 13 can slide on the outer casing 1, thereby connecting the air inlets 131 sequentially with the air intake channels 141. By sliding the gas flow control switch 13, the user can align different numbers or diameters of air inlets 131 with the air intake channels 141, thereby adjusting the airflow into the atomizing core 5 and adjusting the draw resistance and aerosol concentration to meet the personalized needs of different users.

[0035] Working principle: In the initial state, the inlet valve is closed, the shape memory alloy 10 is not energized, and the sealing plug 71 blocks the outlet hole 61 of the sealing cap 6, preventing e-liquid from entering the reservoir 4. When the e-cigarette is activated, the control board 3 receives a signal and controls the battery 2 to supply power to the shape memory alloy 10. Upon energization, the shape memory alloy 10 heats up, undergoing a martensitic-to-austenitic phase transformation. The shape memory alloy 10 contracts, pulling the sealing plug 71 downwards via the rigid moving block 9. The sealing plug 71 compresses the thin wall 72, causing it to elastically deform and detach from the outlet hole 61, opening the inlet passage. Under gravity, the e-liquid in the reservoir 4 flows into the atomizer core 5 through the outlet hole 61, the inlet channel 73, and the inlet hole 51, coming into contact with the heating element. Simultaneously, the heating element of the atomizer core 5 is energized, atomizing the e-liquid into an aerosol. The user's inhaled airflow carries the aerosol for inhalation. When the user stops inhaling, the control board 3 stops supplying power. The shape memory alloy 10 cools down after power loss, undergoing a reverse phase transformation from austenite to martensite. The shape memory alloy 10 returns to its natural length, and the contraction force disappears. The thin-walled part 72 recovers its deformation under its own elasticity. Simultaneously, the elasticity of the return spring 11 pushes the rigid moving block 9 and the sealing plug 71 upwards, causing the sealing plug 71 to re-seal the liquid outlet 61, closing the liquid inlet valve, stopping the e-liquid supply, and stopping the atomizer core 5 from working. The entire opening and closing process is smooth and noiseless. Furthermore, the shape memory alloy 10's driving mechanism eliminates the need for complex transmission mechanisms, resulting in a compact structure and high reliability. This effectively solves the problems of complex configuration, high noise, large size, and high cost associated with traditional solenoid valves or motor valves. It also ensures accurate e-liquid supply and reliable sealing, greatly improving the user experience and product lifespan of electronic cigarettes.
