Description

Technical Field

[0001] This application relates to the field of electronic atomization device technology, specifically to a manual valve open-oil electronic cigarette. Background Technology

[0002] In the technical architecture of e-cigarette products, there is still room for optimization in the coordinated design of e-liquid supply control and leak prevention functions. Existing products generally adopt a split design: users control the e-liquid flow via a manual e-liquid supply switch, which theoretically seals the e-liquid channel to prevent leakage when closed; while the vapor regulator switch is an independent module, adjusting the airflow through a rotation or sliding mechanism to optimize the vapor flavor. This design logic seems reasonable, but in practical applications, it exposes structural redundancy issues. Specifically, the structural contradictions of the split design are mainly reflected in two aspects: First, the transmission mechanisms of the two independent systems (e-liquid supply and vapor regulator) require separate operating interfaces (such as knobs and sliders), leading to an increase in the number of openings in the outer casing, affecting both the overall aesthetics and the risk of liquid infiltration; second, the number of components and assembly processes for the dual systems far exceed actual functional requirements. For example, the threaded sealing structure of the e-liquid supply switch and the guide rail limit device of the vapor regulator switch need to be processed and adjusted separately, significantly increasing production costs.

[0003] To address the aforementioned issues, developing integrated control mechanisms has become an inevitable choice for technological upgrading. Utility Model Content

[0004] The purpose of this application is to overcome at least one deficiency of the prior art and provide a manual valve e-cigarette that combines the e-liquid supply switch and the gas adjustment switch through structural innovation, so as to retain the gas adjustment function while ensuring that a single knob can realize the dual functions of e-liquid on / off and leak prevention.

[0005] To achieve the above objectives, this application discloses a manual valve-operated e-cigarette. The e-cigarette includes a body with an atomization channel, an oil storage chamber disposed within the body, a valve mechanism for controlling the opening and closing of the oil supply to the oil storage chamber, and a switch part disposed on the side wall of the body. The switch part can slide linearly along the axial direction and form a kinematic cooperation with the valve mechanism, thereby driving the valve mechanism to switch the oil supply opening and closing state.

[0006] An atomizing component is provided in the main atomizing channel. The atomizing component is connected to the oil storage chamber through an oil circuit interface. The valve body mechanism is installed at the connection port between the oil storage chamber and the atomizing component. It includes a valve core that is sealed to the connection port and a rotary transmission mechanism that drives the valve core to make axial displacement. The rotary transmission mechanism forms a motion coupling with the switch part through a linkage structure.

[0007] The main atomizing channel of the main body is connected to an air intake channel at the bottom. The air intake port of the air intake channel is in a positional relationship with the switch. When the switch slides linearly, it adjusts the shielding relationship with the air intake port to realize the air intake being closed or opened.

[0008] Furthermore, the main body is equipped with a battery and a control board. The battery is electrically connected to the control board through wires, and the control board further forms a power supply circuit with the atomizing component.

[0009] Furthermore, the rotary transmission mechanism includes a rotating part with a wedge-shaped guide surface. One end of the rotating part is kinematically engaged with the valve core via a keyway, and the other end is also provided with a wedge-shaped guide surface. Correspondingly, the switching part is provided with a contact part that makes sliding contact with the wedge-shaped guide surface. When the switching part slides linearly along the axial direction, the interaction between the contact part and the wedge-shaped guide surface causes the rotating part to rotate circumferentially, which is then converted into axial movement of the valve core through the keyway engagement. Specifically, when the switching part moves upward, it generates a positive rotational torque that causes the valve core to move downward to seal; conversely, it generates a reverse rotational torque that causes the valve core to move upward to open.

[0010] Furthermore, the rotary transmission mechanism also includes an elastic retaining mechanism, which provides a circumferential retaining torque after the rotating part rotates. In a preferred embodiment, the elastic retaining mechanism includes a bullet-shaped element and a cooperating spring. The tail end of the element is connected to the spring, allowing it to be axially displaceable within the body. Its end engages with a pre-set positioning groove on the rotating part. When the rotating part deflects, the element deflects in the direction of rotation and maintains the rotational positioning of the rotating part through the spring preload.

[0011] In an optional implementation, the air intake port of the air intake channel adopts an array-type air intake hole structure, and the switching part selectively blocks all or part of the air intake holes through linear sliding displacement, so as to realize the continuous adjustment of the air passage opening and closing and the air intake cross-sectional area.

[0012] In another alternative, the air intake port is configured as a long strip-shaped air intake slit extending along the sliding direction of the switch section, and the gradual shielding adjustment of the air intake slit is achieved by the linear sliding displacement of the switch section.

[0013] Compared with the prior art, this application has at least one of the following beneficial effects:

[0014] 1. This application integrates the valve core drive mechanism and the air intake adjustment mechanism into a single linear sliding switch. Users only need to perform axial push-pull operations to simultaneously control the oil circuit on / off and the air intake volume adjustment, completely solving the risk of misoperation caused by the separation of the oil circuit switch and the air adjustment knob in traditional electronic cigarettes, and significantly improving the efficiency of human-computer interaction.

[0015] 2. The elastic holding mechanism of this application applies a directional holding torque to the rotating drive rod through the cooperation of the bullet-shaped elastic element and the limiting groove, so that the switch can be stably locked in any adjustment position, avoiding changes in valve opening due to vibration or accidental contact, and ensuring the consistency of atomization parameters.

[0016] 3. The air intake port structure of the air intake channel in this application is an array of air intake holes or a long strip of air intake slits, which can flexibly match the air intake mode according to different atomization requirements. At the same time, the standardized interface design of the rotary drive rod and the valve core facilitates the adaptation to a variety of atomization components, significantly improving product scalability and production line compatibility.

[0017] 4. By eliminating the traditional independent gas adjustment knob and related transmission components, this application reduces the number of parts in the overall structure. This reduces assembly complexity and effectively avoids the problem of tolerance accumulation caused by the gaps between multiple parts, thus significantly improving product yield and long-term stability.

[0018] The beneficial effects listed above are not exhaustive of all advantages. Other potential beneficial effects and detailed technical implementation methods will be further disclosed in the embodiments or other descriptive sections of this application. Attached Figure Description

[0030] See attached document Figures 1 to 3 This application relates to a manually operated valve-operated e-cigarette, the overall structure of which is designed to enable convenient manual control of the e-liquid supply and air intake. The e-cigarette mainly consists of a main body 1, an e-liquid storage chamber 2, a valve mechanism 3, and a switch 4.

[0031] Specifically, the main body 1, serving as the supporting structure of the entire electronic cigarette, is typically made of high-strength plastic or metal, possessing excellent corrosion resistance and mechanical strength. The main body 1 houses the main atomizing channel 11, with an air intake channel 12 connected to its bottom. The e-liquid storage chamber 2, located within the main body 1, stores e-liquid and is typically made of glass or food-grade plastic to ensure the quality and safety of the e-liquid. The valve mechanism 3, installed at the connection between the e-liquid storage chamber 2 and the atomizing assembly, includes a valve core 31 and a rotary transmission mechanism 32. The switch 4, located on the side wall of the main body 1, can slide linearly along the axial direction and kinematically engages with the valve mechanism 3, thereby driving the valve mechanism 3 to switch the e-liquid supply on / off state.

[0032] Specifically, an atomizing component 5 is installed in the main atomizing channel 11 and is connected to the oil storage chamber 2 through an oil circuit interface. The atomizing component 5 typically includes components such as an atomizing core and oil-guiding cotton. Its specific structure and working principle are well-known to those skilled in the art and will not be disclosed in detail here.

[0033] The rotary transmission mechanism 32 includes a rotating part 321, the center of which is axially connected to the main body 1 via a shaft, achieving a rotatable engagement. Simultaneously, one end of the rotating part 321 forms a kinematic engagement with the valve core 31 via a keyway, and the other end is provided with a wedge-shaped guide surface 322. The switching part 4 is provided with a contact part 41 that forms a sliding contact with the wedge-shaped guide surface 322. When the switching part 4 slides linearly along the axial direction, the interaction between the contact part 41 and the wedge-shaped guide surface 322 causes the rotating part 321 to rotate circumferentially, which is then converted into axial movement of the valve core 31 through the keyway engagement. For example, when the switching part 4 moves upward, it generates a positive rotational torque that causes the valve core 31 to move downward to seal; conversely, it generates a reverse rotational torque that causes the valve core 31 to move upward to open.

[0034] Furthermore, the rotary transmission mechanism 32 is also provided with an elastic retaining mechanism 33, which provides a circumferential retaining torque after the rotating part 321 rotates. More preferably, the elastic retaining mechanism 33 includes a bullet-shaped element 331 and a cooperating spring therewith. The tail end of the element 331 is connected and engaged with the spring. The element 331 is axially displaceable and assembled in the body 1. The end of the element 331 normally engages with a pre-set positioning groove on the rotating part 321. The positioning groove is located on the axial position of the rotating part 321 in its neutral state. When the rotating part 321 deflects, the element 331 deflects in the direction of rotation, and the rotational positioning of the rotating part 321 is maintained by the spring preload.

[0035] Understandably, the elastic retaining mechanism 33 ensures that the rotating part 321 can remain in the corresponding position after being rotated under force, thus improving the stability and reliability of the valve body mechanism 3. For example, when the user operates the switch part 4, the element 331 in the elastic retaining mechanism 33 provides a circumferential retaining torque through the spring preload, so that the rotating part 321 can be stably maintained in the sealed or open state of the valve core 31, avoiding changes in the position of the valve core 31 due to external vibrations or other factors, which would affect the normal use of the electronic cigarette.

[0036] Furthermore, the air intake port 121 of the air intake channel 12 is positionally corresponding to the switch unit 4. When the switch unit 4 slides linearly, it adjusts the shielding relationship with the air intake port 121, thereby closing or opening the air intake. As an improvement, see attached... Figure 4 As shown, the air intake port 121 adopts an array-type air intake hole structure. The switch part 4 selectively blocks all or part of the air intake holes through linear sliding displacement, realizing continuous adjustment of the air passage opening and closing and the air intake cross-sectional area. Alternatively, as shown in the attached... Figure 5As shown, the air intake port 121 is configured as an elongated air intake slit extending along the sliding direction of the switch part 4. The gradual shielding adjustment of the air intake slit is achieved through the linear sliding displacement of the switch part 4. The size and layout of the air intake port or air intake slit can be optimized according to actual needs to achieve the best air intake effect.

[0037] In a specific implementation, the main body 1 also includes a battery 6 and a control board 7. The battery 6 is electrically connected to the control board 7 via wires. The control board 7 further forms a power supply circuit with the atomizing assembly 5, providing electrical energy to the atomizing assembly 5 to achieve the atomization of the e-liquid. The battery 6 is typically a lithium battery, which has high energy density and a long service life. The control board 7 typically includes components such as a microcontroller and power management circuits. Its specific design and connection methods are well-known to those skilled in the art and will not be described in detail here.

[0038] Specifically, when the user needs to turn on the e-liquid supply, they push the switch part 4 downwards along the axial direction. The contact part 41 of the switch part 4 interacts with the wedge-shaped guide surface 322 of the rotating part 321, generating a reverse rotational torque. This causes the rotating part 321 to rotate circumferentially, and through the keyway engagement, it drives the valve core 31 to move upwards and open. The e-liquid in the e-liquid storage chamber 2 flows to the atomizing assembly 5 through the oil circuit interface. At the same time, the downward movement of the switch part 4 adjusts the shielding relationship with the air intake port 121, opening the air intake channel 12. Outside air enters the main atomizing channel 11, assisting the atomizing assembly 5 in atomizing work. When the user needs to turn off the e-liquid supply, they push the switch part 4 upwards along the axial direction. The contact part 41 of the switch part 4 interacts with the wedge-shaped guide surface 322 of the rotating part 321, generating a positive rotational torque. This causes the rotating part 321 to rotate circumferentially, and through the keyway engagement, it drives the valve core 31 to move downwards and seal, preventing the e-liquid in the e-liquid storage chamber 2 from flowing to the atomizing assembly 5. At the same time, the upward movement of the switch section 4 adjusts the shielding relationship with the air intake port 121, closing the air intake passage 12.

[0039] It should be noted that the specific design and connection methods of the atomizing component 5, battery 6, and control board 7 in the above embodiments are well-known technologies to those skilled in the art and will not be disclosed in detail here. Furthermore, the specific structure of the air intake channel 12 and the linear sliding displacement adjustment method of the switch part 4 can also be adjusted according to actual needs, and these adjustments and improvements are all within the protection scope of this application.

[0040] In summary, the manual valve e-cigarette of this embodiment, through its reasonable design structure, achieves manual control of oil supply and air intake, making it easy to operate. Furthermore, the tight coordination between all components meets the needs of users in different usage scenarios, improving the user experience and safety of e-cigarettes.
