Description

Technical Field

[0001] The present application relates to the field of electronic cigarettes, and in particular to a dynamic switch valve liquid electronic cigarette. Background Art

[0002] As a new product, electronic cigarettes have been widely used and recognized in the market in recent years. Existing electronic cigarettes usually use a valve-type mechanical structure with electromagnetic opening and closing to achieve oil supply control. Mechanical electromagnetic valves achieve rapid opening and closing through electromagnetic induction. They have fast response speed and high controllability. They are widely used in industrial and civil equipment that require high precision and high response speed. However, in the field of electronic cigarettes, this structure is not completely applicable. In addition to mechanical electromagnetic valves, some electronic cigarettes also use electric manual valves to control the oil supply. This valve requires the user to manually operate the electric switch to control the oil volume. However, in actual use, this type of valve also has some significant problems.

[0003] Although mechanical electromagnetic valves have significant advantages in some aspects, they also expose some shortcomings in the actual application of electronic cigarettes. First, the internal structure of mechanical electromagnetic valves is relatively complex and contains multiple precision components, which complicates the manufacturing process. Secondly, due to the high manufacturing and assembly requirements of mechanical electromagnetic valves, their production costs are significantly increased, which is not conducive to the low-cost market positioning of electronic cigarette products. In addition, the assembly of mechanical electromagnetic valves requires high-precision processes and equipment, which increases the complexity and maintenance costs of the production line. Although the mechanical electromagnetic valve has a fast response speed, the electronic cigarette does not have high requirements for response speed, and this high performance fails to reflect its due value in electronic cigarettes. Finally, electronic cigarettes have high requirements for sealing, and mechanical electromagnetic valves may have problems with reduced sealing during frequent opening and closing, affecting the user experience.

[0004] There are also some significant drawbacks for electronic cigarettes that use electric manual valves. Users often forget to close the electric manual valves after use, resulting in oil leakage, wasting oil and polluting the environment. In addition, due to the subjectivity and imprecision of manual operation, it is difficult to maintain a stable oil output, affecting the user experience.

[0005] The above problems are mainly caused by the mismatch of design intentions, the complex manufacturing process of mechanical solenoid valves and electric manual valves, high material costs, and user operating errors. The original design intention of the mechanical solenoid valve is to meet the high precision and fast response of the industrial level, while e-cigarettes, as consumer products, are more concerned about cost and practicality. Mechanical solenoid valves require multiple precision machining processes, which increases manufacturing costs and time. In order to achieve the high performance of mechanical solenoid valves, their materials are usually expensive, which contradicts the low-cost requirements of e-cigarette products. The complex structure of the mechanical solenoid valve makes it difficult to maintain and repair it during use, which increases the burden on consumers. The manual valve relies on the user's operation, and it is easy to forget to close it due to negligence, resulting in oil leakage problems, and the accuracy of manual control of the oil output is not high, which affects the use effect of the e-cigarette.

[0006] In order to better meet market demand, it is of great significance and value to develop a powered switch valve Ming oil electronic cigarette with simpler structure, lower cost and better sealing performance. Utility Model Content

The term "and / or" used in the specification includes any and all combinations of one or more of the relevant listed items. Example

[0042] like Figures 1 to 3 As shown, this embodiment discloses a powered switch valve liquid electronic cigarette, which includes the following main components:

[0043] The electronic cigarette body 1, the oil tank 2, the channel 3, the atomizing core 4, the power switch valve 5, the cotton core 6, the oil outlet 7, the power unit 8, the rubber ring 9, the limit block 10, the positioning block 11, the guide block 12, the guide channel 13, the main control board and the battery.

[0044] In this embodiment, the electronic cigarette body 1 is made of solid metal or plastic, and a channel 3 is provided inside. One end of the channel 3 is connected to the mouthpiece, and the other end is connected to the air inlet. Air is inhaled through the air inlet, passes through the channel 3 and reaches the mouthpiece, and when the user smokes, the smoke is inhaled through the mouthpiece.

[0045] In this embodiment, the oil tank 2 is used to store the e-liquid, and is usually made of a transparent or translucent plastic material, which is convenient for observing the amount of the e-liquid. The connection between the oil tank 2 and the electronic cigarette body 1 is designed with a sealing structure to prevent the e-liquid from leaking. At least one limit block 10 is provided in the oil tank 2, which cooperates with the rubber ring 9 to limit its radial range of motion.

[0046] It should be understood that the oil tank 2 is provided with at least one air inlet or one-way air inlet valve at the top or near the top (higher than the level of the e-liquid), and this design enables the e-liquid to be smoothly delivered from the oil outlet 7. If the oil tank 2 is purely sealed, the e-liquid will not be able to flow out due to the atmospheric pressure.

[0047] In this embodiment, the powered switch valve 5 is composed of a rubber ring 9 and a power unit 8. The rubber ring 9 is made of a high temperature resistant and corrosion resistant silicone material and has certain elastic deformation characteristics. The structure of the rubber ring 9 is designed to be annular to ensure that it can fit tightly against the outer wall of the channel 3 and seal the oil outlet 7 through the material. The width and thickness of the rubber ring 9 are precisely designed to ensure that it can move smoothly and open and close the oil outlet 7 under the drive of the power unit 8. When the power unit 8 moves to one side away from the channel 3, the rubber ring 9 is equivalent to being tightened, and the adaptability of its deformable material itself is used to make most of the rubber ring 9 close to the outer wall of the channel 3, thereby achieving the sealing of the oil outlet 7.

[0048] More specifically, the power unit 8 may be an electromagnetic telescopic device, and the specific structure is as follows: the electromagnetic telescopic device includes an electromagnetic coil, a movable shaft, a return spring, a fixed frame and a sealed housing. The electromagnetic coil, the return spring and the fixed frame are all located in the sealed housing, and the movable shaft partially extends out of the sealed housing.

[0049] In the above structure, the electromagnetic coil is wound with copper wire, and the power on and off of the coil is controlled by the main control board. One end of the movable shaft is fixed on the rubber ring 9, and the other end passes through the electromagnetic coil and is connected to the reset spring. The reset spring is installed in the fixed frame, between the movable shaft and the fixed frame, to provide a restoring force. When the electromagnetic coil is energized, the magnetic field generated drives the movable shaft to move along the axial direction of the fixed frame, driving the rubber ring 9 to move and open the oil outlet 7. When the electromagnetic coil is de-energized, the reset spring restores the movable shaft to its initial position, and the rubber ring 9 reseals the oil outlet 7. The structural design of the electromagnetic telescopic device ensures the smooth movement of the rubber ring 9 and can accurately control the opening and closing of the oil outlet 7.

[0050] In this embodiment, the atomizer core 4 is installed in the channel 3, close to the bottom of the oil tank 2, and the main material is ceramic or metal mesh, which can evenly heat the smoke oil. The heating temperature of the atomizer core 4 is controlled by the main control board to atomize the smoke oil and form smoke for the user to inhale. The cotton core 6 is located in the channel 3 and between the oil outlet 7 and the atomizer core 4. The cotton core 6 is used to store oil and supply oil to the atomizer core 4, so that the oil outlet 7 indirectly supplies oil to the atomizer core 4.

[0051] It should be understood that the main control board is the core control device of the electronic cigarette, including a power management module and a sensor interface. The power management module is responsible for managing the charge and discharge status of the battery to ensure the power supply of the electronic cigarette in various working modes. The sensor interface is connected to the sensing device in channel 3 or connected to channel 3, and triggers the heating process of the atomizer core 4 by sensing the user's smoking action. The main control board adjusts the heating time of the atomizer core 4 according to the sensor signal to achieve efficient atomization of the smoke oil. The main control board is also responsible for driving the electromagnetic coil of the electromagnetic telescopic device, and by precisely controlling the power on and off of the electromagnetic coil, it realizes the movement control of the rubber ring 9, thereby opening and closing the oil outlet 7.

[0052] During operation, the main control panel controls the opening time of the power switch valve 5 to control the oil output, thereby adjusting the taste to meet the needs of different users, making the use of the electronic cigarette more flexible.

[0053] In this embodiment, the additional components and design details include a limit block 10 , a guide block 12 and a locking block 11 .

[0054] The limit block 10 is arranged at a position of the oil tank 2 close to the channel 3 and cooperates with the rubber ring 9 to limit its range of movement and ensure accurate opening and closing of the oil outlet 7.

[0055] The limiting block 10 avoids the oil outlet 7 of the channel 3 to ensure that the rubber ring 9 will not be disturbed when opening and closing the oil outlet 7, thereby ensuring the sealing and stability of the oil outlet 7.

[0056] The limiting block 10 is designed to prevent the rubber ring 9 from deviating from the position of the oil outlet 7 during radial movement, thereby ensuring the accuracy of each opening and closing action.

[0057] The number of the limiting blocks 10 is usually two, and they are symmetrically arranged with the channel 3 as the center to balance the force on the rubber ring 9 and further ensure the stability of its movement.

[0058] The function of the guide block 12 is to increase the matching surface between the rubber ring 9 and the channel 3, so that the circumference of the rubber ring 9 can better match the channel 3, ensuring that the rubber ring 9 can move stably during the opening and closing process.

[0059] Through the design of the guide block 12, the contact area between the rubber ring 9 and the channel 3 is increased, thereby improving the sealing effect.

[0060] The clamping block 11 clamps the rubber ring 9 partially on the outer wall of the channel 3, providing an additional fixing effect to prevent the rubber ring 9 from sliding or rotating on the outer wall of the channel 3. The clamping block 11 is located on the extension line of the moving direction of the power unit 8, ensuring that the power unit 8 can accurately control the movement trajectory of the rubber ring 9 when driving it.

[0061] The design of the positioning block 11 not only increases the fixation of the rubber ring 9, but also ensures the close contact between the rubber ring 9 and the outer wall of the channel 3, thereby improving the sealing effect.

[0062] A sensing device is provided in the channel 3 or at other positions connected to the channel 3, and is connected to the main control board through the sensing device, so that when the user takes a puff of the cigarette holder, the atomizing core 4 is activated to discharge smoke.

[0063] Since the cotton core 6 is provided, the cotton core 6 itself has the function of storing oil. When the smoke is first smoked, it is not necessary to replenish the oil. After the smoke is finished, the power switch valve 5 is controlled to work to realize the oil replenishment.

[0064] The specific working principle is: when the user smokes, he inhales air through the air inlet, the sensor detects the smoking action, the main control board controls the atomizer core 4 to heat up, and at the same time the power unit 8 drives the rubber ring 9 to move, opening the oil outlet 7, so that the smoke oil enters the atomizer core 4 through the oil outlet 7 for atomization, the atomizer core 4 heats the smoke oil to generate smoke, and the smoke passes through the channel 3 and the mouthpiece and enters the user's mouth.

[0065] Although the exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the scope of protection of the present disclosure as defined by the claims. The present disclosure is defined by the appended claims, and the equivalents of these claims are also included.
