[0037] Reference Figure 1-5 As shown, an oil leakage-proof atomizer is provided with an oil storage tank 100 and an atomizer core 200, and the atomizer core 200 is detachably installed in the atomizer;

[0038] When the atomizer is fixed in the atomizer, the oil supply hole 110 on the side wall of the oil storage tank 100 corresponds to the position of the oil inlet hole 210 on the oil inlet of the atomizer core 200;

[0039] A gap is provided between the oil storage tank 100 and the atomizer core 200, and a movable pipe 300 is slidably provided in the gap. A through hole 310 is provided on the movable pipe 300, and the movable pipe 300 has a first position state and a second position state in the gap;

[0040] When the movable pipe 300 is in the first position, the through hole 310 corresponds to the oil supply hole 110 of the oil storage tank 100 so that the atomizer core 200 is connected to the oil storage tank 100;

[0041] When the movable pipe 300 is in the second position, the position of the through hole 310 is offset from the oil supply hole 110 of the oil storage tank 100 , and the movable pipe 300 isolates the atomizer core 200 from the oil storage tank 100 .

[0042] When the atomizer is working normally, the movable pipe 300 is in the first position state, and its through hole 310 corresponds to the oil supply hole 110 of the oil storage bin 100, allowing the smoke oil to flow, and the atomizer core 200 is connected with the oil storage bin 100. When replacing the atomizer core 200, the user operates to move the movable pipe 300 to the second position state, at which time the through hole 310 and the oil supply hole 110 are staggered, cutting off the oil path to prevent the smoke oil from leaking from the oil storage bin 100. The movable pipe 300 slides in the gap between the oil storage bin 100 and the atomizer core 200, and the position state is switched by the user operating the support member 600.

[0043] By switching the position of the movable pipe 300, the atomizer core 200 and the oil storage bin 100 can be isolated without affecting normal use, so that the atomizer core 200 can be replaced conveniently. By switching the position of the movable pipe 300, the connection between the oil storage bin 100 and the atomizer core 200 is effectively isolated, and oil leakage is prevented when the atomizer core 200 is replaced, which provides a better user experience and saves the cost of e-liquid when the atomizer core 200 is replaced. The movable pipe 300 is slidably installed between the atomizer core 200 and the oil storage bin 100, which reduces the occupied space and maintains the compactness of the entire atomizer.

[0044] In this embodiment, the oil storage tank 100 is annular, one end of the oil storage tank 100 is fixedly connected to the cigarette holder assembly 400, and the inner ring of the oil storage tank 100 is an airway connected to the cigarette holder assembly 400;

[0045] The atomizer core 200 is detachably installed in the airway, and the movable pipe 300 is slidably installed between the atomizer core 200 and the oil storage tank 100 .

[0046] The annular oil storage tank 100 design can make more effective use of space and make the entire atomizer more compact. The inner ring serves as an airway and is connected to the mouthpiece assembly 400, ensuring smooth airflow and a good smoking experience. The detachable design of the atomizer core 200 is convenient for users to replace and clean, and improves the maintainability of the product. The sliding installation and position control mechanism of the movable pipe 300 can effectively prevent oil leakage when replacing the atomizer core 200.

[0047] In this embodiment, a limiting portion 320 is provided on the surface of the movable pipe 300, and a clamping portion 120 corresponding to the limiting portion 320 is provided on the surface of the airway. The limiting portion 320 cooperates with the clamping portion 120 to limit the rotation of the movable pipe 300. The design takes into account that the precise position of the movable pipe 300 is crucial during operation, so the matching design of the limiting portion 320 and the clamping portion 120 is introduced. By limiting the rotation of the movable pipe 300, the position displacement of the through hole 310 caused by misoperation when the user replaces the atomizer core 200 is avoided. Ensure the stability of the movable pipe 300 during operation to avoid affecting the normal use of the atomizer due to changes in the pipe position.

[0048] The movable pipe 300 cooperates with the clamping part 120 on the surface of the airway through the limiting part 320 on its surface to achieve precise positioning. When the movable pipe 300 switches the position state between the first position state and the second position state, the cooperation between the limiting part 320 and the clamping part 120 effectively prevents unnecessary rotation of the pipe. Ensure that the through hole 310 remains consistent with the designed position at all times, avoid horizontal deviation of the through hole 310, and ensure the smooth flow of the oil circuit or effective cutting off. Preventing the movable pipe 300 from rotating reduces the risk of oil leakage caused by improper position of the pipe and improves safety of use. When replacing the atomizer core 200, the user does not have to worry about adjusting the position of the pipe, and can complete the replacement process more quickly and conveniently.

[0049] In this embodiment, a spring 500 is further provided in the airway, one end of the spring 500 abuts against the mouthpiece assembly 400, and the other end abuts against the movable pipe 300;

[0050] The spring 500 is used to apply elastic force to the movable pipe 300 to slide toward the second position state.

[0051] By arranging the spring 500 in the airway, the position of the movable pipe 300 is automatically controlled, reducing the manual intervention of the user during the operation. The elastic force of the spring 500 is used as a driving force to help the movable pipe 300 switch between two states, thereby improving the convenience and accuracy of the operation. The spring 500 is integrated into the airway to optimize the overall structure and avoid the complexity and failure risk that may be caused by the external spring 500.

[0052] When the user replaces the atomizer core 200 or performs maintenance, there is no need to manually move the movable pipe 300 to the second position state. The elastic force of the spring 500 simplifies this process. The spring 500 ensures that the movable pipe 300 will be stably maintained in the second position state when not in operation, preventing oil leakage caused by forgetting to close the oil circuit. The automatic action of the spring 500 improves the efficiency of the transition from the first position state to the second position state and reduces the waiting time of the user.

[0053] In this embodiment, a limiting flange 330 is provided on the surface of the movable pipe 300, and a limiting step 130 is provided in the airway;

[0054] When the limiting flange 330 abuts against the limiting step 130 , the movable pipe 300 is located in the second position state.

[0055] The movable pipe 300 is precisely positioned at a specific position by the cooperation of the limiting flange 330 and the limiting step 130, ensuring stability and reliability in the second position state. This prevents the user from accidentally moving the movable pipe 300 to a wrong position during operation, resulting in oil leakage or other functional failures. The elastic force of the spring 500 cooperates with the limiting flange 330 to automatically fix the movable pipe 300 in the second position state, reducing the complexity of user operation.

[0056] The limiting flange 330 of the movable pipe 300 abuts against the limiting step 130 in the airway to ensure that the movable pipe 300 is accurately in the second position state. In the second position state, the spring 500 applies elastic force to the limiting flange 330 to ensure that the movable pipe 300 will not be displaced due to external force or vibration.

[0057] When the movable pipe 300 needs to be converted to the first position state, the user overcomes the elastic force of the spring 500 by operating the support member 600 or other mechanisms to achieve the state conversion.

[0058] The user does not need to manually fix the movable pipe 300, and the cooperation between the spring 500 and the limiting flange 330 simplifies the operation process. In the second position state, the fixation of the movable pipe 300 reduces the risk of oil leakage caused by position deviation. The precise positioning and automatic fixing mechanism improve the safety of the entire system and reduce the possibility of operating errors.

[0059] In this embodiment, a support member 600 is also included, and the support member 600 is detachably mounted on the other end of the oil storage tank 100;

[0060] When the support member 600 is fixed to the other end of the oil storage tank 100 , the support member 600 is used to squeeze the movable pipe 300 so that the movable pipe 300 is located in the first position state.

[0061] The support member 600 is designed to fix the movable pipeline 300 in the first position when needed to ensure smooth oil flow; and the cooperation between the spring 500 and the limit flange 330 stably fixes the movable pipeline 300 in the second position when the oil flow is not needed to prevent oil leakage.

[0062] The detachable design of the support member 600 allows the user to easily install and replace it, which improves the modularity and user-friendliness of the atomizer. The support member 600 not only fixes the atomizer core 200, but is also responsible for squeezing the active pipe 300 to the first position state, realizing dual functions and simplifying the structure. When the atomizer core 200 needs to be replaced, the retreat of the support member 600 allows the active pipe 300 to automatically move to the second position state under the action of the spring 500, realizing an automated control process.

[0063] When the atomizer is working normally, the support member 600 is fixed to the other end of the oil storage tank 100, maintaining the movable pipeline 300 in the first position, allowing the atomizer core 200 to communicate with the oil storage tank 100 to perform normal atomization. When the user needs to replace the atomizer core 200, first remove the support member 600 from the other end of the oil storage tank 100 so that the movable pipeline 300 is no longer squeezed by the support member 600. After the support member 600 is withdrawn, the movable pipeline 300 automatically moves to the second position under the elastic force of the spring 500, blocking the oil supply hole 110 of the oil storage tank 100, preventing oil leakage during the replacement of the atomizer core 200.

[0064] The design of the support member 600 simplifies the process of replacing the atomizer core 200. The user does not need to manually adjust the movable pipe 300, but only needs to remove the support member 600. When replacing the atomizer core 200, the retreat of the support member 600 and the action of the spring 500 automatically block the oil path, effectively preventing oil leakage and protecting the user and the device.

[0065] In this embodiment, a positioning member 610 for fixing the atomizer core 200 is provided on the surface of the support member 600;

[0066] The groove wall of the positioning member 610 is used to squeeze the movable pipe 300 to slide toward the first position.

[0067] The support member 600 is designed to have dual functions. On the one hand, it fixes the atomizer core 200, and on the other hand, it maintains the movable pipe 300 in the first position state, thereby improving the design efficiency. Through the design of the positioning member 610, the correct position of the atomizer core 200 in the airway is ensured, while the position of the movable pipe 300 is controlled, thereby enhancing the stability of the overall structure. The threaded connection between the support member 600 and the oil storage tank 100 provides a simple and firm installation and disassembly method, which is convenient for users to operate.

[0068] The user screws the support member 600 to the oil storage tank 100, and uses the positioning member 610 on the support member 600 to fix the atomizer core 200 to ensure that it is correctly installed in the airway. The groove wall of the positioning member 610 squeezes the active pipeline 300, so that it is stably maintained in the first position state, thereby allowing the oil path between the atomizer core 200 and the oil storage tank 100 to be unblocked. When the atomizer core 200 needs to be replaced or maintained, the user can unscrew the support member 600, release the squeezing of the active pipeline 300, and make the active pipeline 300 automatically move to the second position state under the action of the spring 500 to block the oil path.

[0069] The positioning member 610 simultaneously fixes the atomizer core 200 and maintains the position of the movable pipe 300, which simplifies the structure and reduces the need for additional components. When replacing the atomizer core 200, the unscrewing action of the support member 600 automatically blocks the oil circuit, effectively preventing oil leakage and protecting the user and the equipment. The threaded connection design of the support member 600 makes installation and disassembly simple, making it convenient for users to replace and clean the atomizer core 200.

[0070] In this embodiment, a sealing ring 340 is provided on the surface of the movable pipe 300, and two sealing rings 340 are respectively located at the upper and lower sides of the through hole 310;

[0071] When the movable pipe 300 is in the first position state or the second position state, the two sealing rings 340 are also located at the upper and lower sides of the oil supply hole 110 respectively.

[0072] By providing a sealing ring 340 on the surface of the movable pipe 300, the sealing performance between the oil storage bin 100 and the movable pipe 300 is enhanced, and the leakage of the smoke oil is effectively prevented. The design of the sealing ring 340 enables the movable pipe 300 to maintain a good seal with the oil supply hole 110 whether in the first position state or the second position state. The presence of the sealing ring 340 simplifies the maintenance process because they can be easily inspected and replaced to maintain long-term sealing performance.

[0073] The sealing ring 340 is precisely placed on the upper and lower sides of the through hole 310 of the movable pipe 300 to ensure that the sealing ring 340 can be aligned with the corresponding position of the oil supply hole 110 when the movable pipe 300 moves to any position. When the movable pipe 300 is in the first position, the sealing ring 340 is located on the upper and lower sides of the oil supply hole 110, allowing the smoke oil to flow smoothly to the atomizer core 200. When the atomizer core 200 needs to be replaced, the movable pipe 300 moves to the second position, at which time the sealing ring 340 still effectively seals the oil supply hole 110 to prevent smoke oil leakage.

[0074] The use of the sealing ring 340 significantly improves the sealing performance between the oil storage bin 100 and the movable pipe 300, reducing the possibility of oil leakage. During the process of replacing the atomizer core 200, the sealing ring 340 ensures that no oil will leak from the oil storage bin 100 even when the movable pipe 300 moves.

[0075] An electronic cigarette includes the above-mentioned atomizer. The electronic cigarette integrates the above-mentioned atomizer design, has the property of preventing oil leakage, and improves the user experience. The user can easily replace the atomizer core 200 as needed, and the maintenance is simple. The spring 500 and the support member 600 are used to realize the automatic switching of the movable pipe 300 between the first position state and the second position state. The sealing ring 340 on the movable pipe 300 ensures that the oil leakage can be effectively prevented in any state.

[0076] The detachable atomizer core 200 is installed in the airway, and the movable pipe 300 is ensured to be in the first position so that the smoke oil can flow to the atomizer core 200. The user activates the electronic cigarette by smoking, and the smoke oil flows from the oil storage tank 100 to the atomizer core 200 through the oil supply hole 110, is heated and converted into steam. When the atomizer core 200 needs to be replaced or maintained, the user unscrews the support 600, and the movable pipe 300 automatically moves to the second position under the action of the spring 500, blocking the oil path and preventing oil leakage during the replacement process.

[0077] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
