Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to an electronic cigarette that can control the synchronous switching on and off of the oil circuit and the electrical circuit. Background Technology

[0002] As an alternative to traditional tobacco, e-cigarettes have seen continuous optimization in atomization technology and user experience in recent years. Existing e-cigarettes typically atomize e-liquid through an oil reservoir, an oil guiding structure, and a heating element. Their working principle relies on a smooth oil supply and timely circuit switching.

[0003] Currently, most electronic cigarettes use mechanical switches or airflow sensors to independently control the on / off state of the circuit, while the on / off state of the oil circuit largely relies on gravity or capillary action for passive adjustment. This design has the following drawbacks: First, when the user stops using the cigarette or closes the oil circuit, the circuit may remain conductive due to delayed disconnection or accidental triggering, causing the heating element to remain powered on and burn dry, accelerating the aging of the heating element and posing a risk of overheating. Second, mechanical switches are prone to wear and tear due to frequent operation, leading to poor contact or failure, while the response sensitivity of the airflow sensor is affected by environmental factors, making it difficult to ensure precise synchronization between the oil circuit and the electrical circuit. Third, during transportation or when not in use, incomplete closure of the oil circuit can easily cause oil leakage, and incomplete circuit disconnection may lead to abnormal battery drain, reducing the device's lifespan. Therefore, this paper proposes an electronic cigarette that can control the synchronous on / off state of the oil circuit and the electrical circuit to solve the above technical problems. Utility Model Content

[0004] The purpose of this invention is to provide an electronic cigarette that can control the simultaneous on / off of the oil circuit and the electrical circuit, addressing the shortcomings of existing technologies. This solves the technical problem that existing electronic cigarettes cannot simultaneously control the on / off of the electrical circuit while controlling the on / off of the oil circuit.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An electronic cigarette with controllable oil circuit and synchronous circuit switching includes an upper shell and a support base installed at the bottom of the upper shell. The top of the support base and the inner side wall of the upper shell together form an oil storage chamber. The support base is equipped with a first heating core assembly. An oil guiding chamber is formed inside the support base. An oil guiding hole is formed on the top of the support base to connect the oil guiding chamber with the oil storage chamber. An oil inlet hole is formed on the outer side of the first heating core assembly to connect with the oil guiding chamber and to guide e-liquid into the chamber. The cigarette also includes a lifting base. The top of the lifting base is provided with a blocking member that extends upward to pass through the support base. The blocking member is coaxially arranged with the oil guiding hole. The lifting base moves up and down with the blocking member to control the opening and closing of the oil guiding hole.

[0007] It also includes an inductive switch component that controls the on / off state of the first heating element assembly circuit based on the up-and-down movement of the blocking component; when the blocking component blocks the oil guide hole to close it, the inductive switch component controls the circuit of the first heating element assembly to disconnect; when the blocking component moves away from the oil guide hole to open it, the inductive switch component controls the circuit of the first heating element assembly to conduct.

[0008] Furthermore, the bottom of the support base is equipped with a main board that is electrically connected to the first heating core assembly. The inductive switch component includes a Hall switch mounted on the main board for controlling the on / off state of its circuit according to the strength of the surrounding magnetic field. The lifting base is equipped with a magnet for changing the strength of the magnetic field around the Hall switch. The lifting base moves up and down to bring the magnet closer to or away from the Hall switch.

[0009] Furthermore, it also includes a lower housing that is snapped onto the upper housing, and a battery that is electrically connected to the motherboard is installed inside the lower housing; the upper housing is a transparent housing, and a sealing sleeve for preventing e-liquid leakage is provided on the bottom contact surface between the support base and the upper housing.

[0010] Furthermore, the bottom of the support base is provided with vertically arranged guide columns, and the lifting seat is slidably mounted on the guide columns; a sliding seat is provided on the outer side of the lower housing, the sliding seat passes through the lower housing and is fixed to the lifting seat, and a sliding groove is formed on the outer wall of the lower housing, and the sliding seat is placed in the sliding groove.

[0011] Furthermore, the support base is equipped with a second heating core assembly partially placed inside the oil storage tank; the top of the upper shell is formed with a mouthpiece, and a smoke guide channel is provided inside the mouthpiece. The top ends of the first heating core assembly and the second heating core assembly are both connected to the smoke guide channel. The bottom of the support base is provided with an air inlet pipe for communicating with the outside air, and the bottom ends of the first heating core assembly and the second heating core assembly are both connected to the air inlet pipe.

[0012] Furthermore, an upper sealing member is provided at the top of the upper housing to block and seal the top ends of the first heating element assembly and the second heating element assembly. A confluence channel is formed inside the upper sealing member to allow the interior of the first heating element assembly and the interior of the second heating element assembly to communicate with the smoke guide channel simultaneously.

[0013] Furthermore, the first heating element assembly includes a first support cylinder and an oil-guiding cotton disposed within the first support cylinder. The oil-guiding cotton is equipped with a first heating element for heating e-liquid. Several oil inlet holes for communicating with the oil guiding chamber are disposed on the side wall of the first support cylinder. The top of the first support cylinder is connected to the confluence channel.

[0014] Furthermore, the second heating element assembly includes a second support cylinder and an oil storage cotton disposed within the second support cylinder. The oil storage cotton contains a second heating element for heating e-liquid. The top of the second support cylinder is connected to the confluence channel.

[0015] Furthermore, a fixed seat is installed at the bottom of the support base, and an air guide channel is formed inside the fixed seat. The bottom ends of the first support cylinder and the bottom ends of the second support cylinder are both connected to the air guide channel. The air inlet pipe is installed on the fixed seat and is connected to the air guide channel.

[0016] Furthermore, the air duct is also equipped with oil-absorbing cotton placed below the first and second support cylinders to prevent e-liquid leakage.

[0017] The beneficial effects of this utility model are as follows: When a user needs to use this electronic cigarette, the lifting base is controlled to move downwards, bringing the blocking component downwards as well. When it reaches the bottom, the blocking component disengages from the oil guide hole to open it. The e-liquid in the oil storage tank flows into the first heating core assembly after passing through the oil guide hole, the oil guide chamber, and the oil inlet hole in sequence. At the same time, the induction switch component controls the circuit of the first heating core assembly to be turned on. When the user inhales, the operation of the first heating core assembly can heat and atomize the e-liquid into smoke.

[0018] When the e-cigarette is not in use, the control stand moves upward to its highest point, and the blocking component re-blocks the oil guide hole to close it, separating the oil reservoir from the inside of the first heating element assembly. This achieves oil-electrode separation, preventing the inside of the first heating element assembly from being soaked in e-liquid for a long time, which could damage the internal parts and improve the service life of the e-cigarette. At the same time as the control stand moves upward to its highest point, the induction switch component controls the circuit of the first heating element assembly to disconnect, stopping the power supply.

[0019] The up-and-down movement of the sliding seat controls the opening and closing of the oil guide hole and the on / off state of the first heating element component circuit, achieving synchronous opening and closing of the circuit and oil circuit. This prevents the first heating element component from dry burning inside when the oil circuit is closed, thus improving safety. In addition, the circuit and oil circuit can be shut off during transportation to prevent e-liquid leakage and unexpected situations in the circuit. Attached Figure Description

Detailed Implementation

[0027] The following is a detailed description of an electronic cigarette with controllable oil circuit and synchronous circuit switching, in conjunction with the accompanying drawings.

[0028] like Figure 1-4 As shown, an embodiment of the present invention, an electronic cigarette with controllable oil circuit and synchronous circuit switching, includes an upper shell 1 and a lower shell 2 that is snapped onto the upper shell 1. A support base 3 is installed at the bottom of the upper shell 1. The top of the support base 3 and the inner side wall of the upper shell 1 together form an oil storage tank 5 for storing e-liquid. The support base 3 is snapped onto the bottom of the upper shell 1, and a sealing sleeve 4 is provided on the contact surface between the support base 3 and the bottom of the upper shell 1 to prevent e-liquid leakage. By filling the gap between the support base 3 and the upper shell 1 with the sealing sleeve 4, the e-liquid in the oil storage tank 5 is prevented from leaking out from the gap, thus improving the sealing performance of the oil storage tank 5.

[0029] The support base 3 is equipped with a first heating core assembly 13, partially placed inside the oil storage chamber 5, for heating and atomizing e-liquid. The support base 3 has an internal oil guiding chamber 6, and its top has an oil guiding hole 7 connecting the oil guiding chamber 6 to the oil storage chamber 5. The outer side of the first heating core assembly 13 has an oil inlet hole 132, communicating with the oil guiding chamber 6 and used to guide e-liquid into it. The e-liquid in the oil storage chamber 5 flows sequentially through the oil guiding hole 7, the oil guiding chamber 6, and the oil inlet hole 132 into the first heating core assembly 13. Operating the first heating core assembly 13 heats and atomizes the e-liquid into vapor for the user to inhale.

[0030] To prevent the first heating element assembly 13 from being soaked in e-liquid for extended periods, a vertically arranged guide post 8 is provided at the bottom of the support base 3. A lifting seat 9 is slidably mounted on the guide post 8, and an upwardly extending plug 10 is provided at the top of the lifting seat 9. The plug 10 extends through the support base 3 to block the oil guide hole 7. When the lifting seat 9 is at its highest point, the plug 10 blocks the oil guide hole 7, thus closing it and separating the oil reservoir 5 from the interior of the first heating element assembly 13. This achieves oil-core separation, preventing the first heating element assembly 13 from being soaked in e-liquid for extended periods, which could damage internal components and extend the lifespan of the electronic cigarette. Furthermore, it prevents e-liquid leakage, improving the user experience.

[0031] To control the opening and closing of the oil guide hole 7, a sliding seat 11 is provided on the outer side of the lower housing 2. The sliding seat 11 passes through the lower housing 2 and is fixed to the lifting seat 9. A groove 12 is formed on the outer wall of the lower housing 2, and the sliding seat 11 is placed in the groove 12. The initial position of the plug 10 is to block the oil guide hole 7 to close it. When the user needs to use this electronic cigarette, the user moves the sliding seat 11 downward in the groove 12, thereby moving the lifting seat 9 and the plug 10 downward together. After the lifting seat 9 moves to the bottom, the plug 10 disengages from the oil guide hole 7 to open it (e.g., Figure 4 As shown, the oil storage tank 5 and the oil guiding chamber 6 are connected through the oil guiding hole 7, allowing the e-liquid in the oil storage tank 5 to enter the first heating core assembly 13. The oil guiding hole 7 is opened and closed by moving the sliding seat 11 up and down, thus controlling the flow of e-liquid. Additionally, an upwardly extending oil guiding part 1001 is formed at the top of the plug 10, with a transverse cross-sectional dimension smaller than the diameter of the oil guiding hole 7. After the plug 10 detaches from the oil guiding hole 7, the oil guiding part 1001 at its top is placed inside the oil guiding hole 7, guiding the e-liquid in the oil storage tank 5 to the oil guiding chamber 6. This prevents a large amount of e-liquid from entering the first heating core assembly 13 during vaping, which could easily cause incomplete atomization. The oil guiding part 1001 also buffers the e-liquid flow rate, improving the user experience. The inner sidewall of the oil guide hole 7 is formed with several annular protrusions. When the plug 10 blocks the oil guide hole 7, the protrusions fill the space between the plug 10 and the inner sidewall of the oil guide hole 7 to increase the sealing performance of the plug 10.

[0032] In this embodiment, a main board 15 for electrical connection with the first heating element assembly 13 is installed at the bottom of the support base 3. A battery 19 for electrical connection with the main board 15 is installed inside the lower housing 2. The main board 15 is a circuit board and is equipped with a Hall switch 16 for controlling the circuit on / off according to the strength of the surrounding magnetic field. The Hall switch 16 is a Hall sensor (model SS441A), which is a transducer that converts a changing magnetic field into a change in output voltage. The Hall switch 16 in this electronic paper achieves reverse trigger control by adjusting the signal processing logic or hardware design, which turns on when the magnetic field moves away and turns off when the magnetic field moves closer. Specifically, the Hall voltage changes with the strength of the surrounding magnetic field. When the magnetic field moves closer, the Hall voltage increases. When it exceeds the threshold, the circuit is turned off. When the magnetic field moves away, the Hall voltage decreases. When it falls below the threshold, the trigger circuit turns on.

[0033] Additionally, a magnet 17 is installed at the bottom of the lifting seat 9 to change the strength of the magnetic field around the Hall switch 16. When the lifting seat 9 is at its highest point, the blocking member 10 blocks the oil guide hole 7, disconnecting the oil circuit. At this time, the magnet 17 is closest to the Hall switch 16 (e.g., Figure 3 As shown, the Hall switch 16 senses the strongest magnetic field, and the circuit is broken. When the lifting seat 9 moves downward to the bottom, the blocking part 10 disengages from the oil guide hole 7, opening the oil passage. At the same time, the lifting seat 9, carrying the magnet 17, moves away from the Hall switch 16, and the magnetic field sensed by the Hall switch 16 gradually weakens, triggering the circuit to conduct. By moving the sliding seat 11 up and down, the circuit and oil passage can be opened and closed synchronously, preventing the first heating core assembly 13 from dry burning when the oil passage is closed, thus improving safety. In addition, during transportation, the circuit and oil passage can be shut off to prevent e-liquid leakage and unexpected situations in the circuit.

[0034] The support base 3 is equipped with a second heating core assembly 14, which is partially placed inside the oil storage tank 5 and is used to heat and atomize e-liquid of a different flavor. The e-liquid stored in the second heating core assembly 14 has a different flavor than the e-liquid stored in the oil storage tank 5. Therefore, the second heating core assembly 14 is not connected to the oil storage tank 5, and the e-liquid in the oil storage tank 5 cannot enter the interior of the second heating core assembly 14. The top of the upper shell 1 is formed with a mouthpiece 20, and a smoke guide channel 21 is provided inside the mouthpiece 20. The top of the first heating core assembly 13 and the top of the second heating core assembly 14 are both connected to the smoke guide channel 21. The bottom of the support base 3 is provided with an air inlet pipe 18 for communicating with the outside air. The bottom of the first heating core assembly 13 and the bottom of the second heating core assembly 14 are both connected to the air inlet pipe 18. The support base 3 is also equipped with a microphone (not shown in the figure) for detecting airflow. The microphone is an airflow sensor. When the user inhales through the mouthpiece 20, the outside air is guided through the air inlet pipe 18 to enter the first heating core assembly 13 and the second heating core assembly 14 respectively. At this time, the flowing air is detected by the microphone to control the first heating core assembly 13 and the second heating core assembly 14 to operate simultaneously. The two heat the e-liquids of different flavors to produce smoke of different flavors. Then the flowing air carries the smoke out and guides it through the smoke guide channel 21. During the guidance process, the smoke of the two flavors is mixed, so that the user can inhale the smoke of the mixed flavor.

[0035] In addition, an upper sealing member 22 is provided at the top of the upper housing 1 to seal the top of the first heating core assembly 13 and the top of the second heating core assembly 14. The upper sealing member 22 has a confluence channel 23 formed within it, allowing the interior of both the first and second heating core assemblies to communicate with the smoke guide channel 21. By sealing the tops of the first and second heating core assemblies 13 and 14 with the upper sealing member 22, e-liquid in the oil storage tank 5 is prevented from entering their interiors from the tops and then leaking out through the smoke guide channel 21. The upper sealing member 22 improves the seal between the tops of both components and the smoke guide channel 21. The upper housing 1 is transparent, allowing users to directly observe the e-liquid usage. Compared to existing displays that rely on algorithmic control, direct observation of the e-liquid level is more accurate.

[0036] like Figure 5As shown, the first heating element assembly 13 includes a first support cylinder 131 and an oil-guiding cotton 133 disposed inside the first support cylinder 131. A first heating element 134 for heating e-liquid is installed inside the oil-guiding cotton 133. Several oil inlet holes 132 for communicating with the oil-guiding chamber 6 are disposed on the side wall of the first support cylinder 131. The top of the first support cylinder 131 communicates with the confluence channel 23. E-liquid in the oil-guiding chamber 6 enters the first support cylinder 131 through the oil inlet holes 132 and is absorbed by the oil-guiding cotton 133. The oil-guiding cotton 133 continuously supplies e-liquid to the first heating element 134, which operates to heat and atomize the e-liquid.

[0037] The second heating element assembly 14 includes a second support cylinder 141 and an oil-retaining cotton 142 disposed within the second support cylinder 141. A second heating element 143 for heating e-liquid is installed inside the oil-retaining cotton 142, continuously supplying e-liquid to the second heating element 143. The top of the second support cylinder 141 is connected to the confluence channel 23. The e-liquid stored in the oil-retaining cotton 142 has a different flavor than the e-liquid stored in the oil storage tank 5. The first heating element 134 and the second heating element 143 operate simultaneously to produce vapors of different flavors, which are then mixed and guided through the confluence channel 23 for the user to inhale.

[0038] In this embodiment, a fixed base 24 is installed at the bottom of the support base 3. An air guide channel 25 is formed inside the fixed base 24. The bottom ends of the first support cylinder 131 and the second support cylinder 141 are both connected to the air guide channel 25. An air inlet pipe 18 is installed on the fixed base 24 and connected to the air guide channel 25. Outside air enters the air guide channel 25 through the air inlet pipe 18 and is then guided through the air guide channel 25 to enter the interiors of the first support cylinder 131 and the second support cylinder 141 respectively. An oil-absorbing cotton 26 is also installed inside the air guide channel 25, positioned below the first support cylinder 131 and the second support cylinder 141 to prevent e-liquid leakage. E-liquid that is not fully atomized on the first heating element 134 and the second heating element 143 flows downwards, exiting from the bottom ends of the first support cylinder 131 and the second support cylinder 141, and is absorbed by the oil-absorbing cotton 26, preventing incompletely atomized e-liquid from leaking out of the air inlet pipe 18 and improving the user experience.

[0039] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0040] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
