Description

Technical Field

[0001] This utility model particularly relates to an oil-proof electronic cigarette. Background Technology

[0002] In existing technologies, the leak-proof design and triggering method of electronic cigarettes are the two core key aspects, mainly including the following representative solutions: The first type of solution focuses on preventing e-liquid leakage. This type of solution typically employs a high-position air intake design, placing the main air intake on the side wall of the cartridge compartment, making the air intake significantly higher than the e-liquid level. This physical level difference effectively prevents e-liquid leakage when the cartridge is stationary. However, the air intake channel in this type of solution is often quite tortuous, resulting in insufficient airflow strength and difficulty in reliably triggering the airflow-sensitive sensor. Therefore, it usually only retains a manual button start mode and cannot achieve the more convenient automatic sensor-based start, resulting in limited functionality.

[0003] The second type of solution focuses on achieving convenient dual-mode triggering (i.e., automatic activation via airflow sensor and manual activation via button). To achieve this function, these products typically maintain the main side air intake while adding an independent dedicated air intake for the airflow sensor at the bottom of the device. While this dual-port structure ensures that the airflow sensor receives sufficient airflow for reliable triggering, the dedicated air intake at the bottom becomes a new leakage point. Condensate or slight leaks of e-liquid generated during use can easily seep out from this bottom air intake, resulting in poor leak-proof performance and affecting the product's cleanliness and reliability. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a leak-proof electronic cigarette: A leak-proof electronic cigarette, comprising: The main body contains a cartridge compartment and an atomizer.

The outlet of the first air intake path leads to the atomizer, and an airflow sensor is provided in the airflow sensing channel. The first air intake path is configured such that, starting from its connection with the air inlet, its airflow path first extends for a predetermined length along a predetermined path different from the direction of direct entry into the atomizer to form a buffer channel, and then changes direction via a turning channel before leading to the atomizer. The triggering mechanism includes the airflow sensor and a manual button located on the main body; The airflow passing through the airflow sensing channel can trigger the airflow sensor to make the atomizer work, and the manual button is configured to trigger the atomizer independently of the airflow sensor.

[0005] Preferably, the main body includes an upper shell and a lower shell connected to each other, the airflow sensor is disposed at the end of the airflow sensing channel for detecting the airflow flowing into the airflow sensing channel, and the main body is provided with a movable cover plate for opening or closing the air inlet.

[0006] Preferably, the lower housing includes a detachably connected first outer shell and a second outer shell. A control board is provided on the first outer shell, and a power supply is provided on the second outer shell. Pins and sockets are correspondingly provided on the mating surfaces of the first and second outer shells, and the control board and the power supply are electrically connected by inserting the pins into the sockets.

[0007] Preferably, the first outer shell is provided with a guide post, and the upper and lower ends of the second outer shell are provided with clamping parts; the two ends of the guide post are respectively assembled into the corresponding clamping parts to achieve preliminary positioning; the lower ends of the first outer shell and the second outer shell are covered by a base plate, and the base plate is provided with through holes corresponding to the positions of the clamping parts. Screws pass through the through holes and are threaded to the ends of the guide posts, thereby realizing the connection and fixation of the first outer shell, the second outer shell and the base plate.

[0008] Preferably, the bottom of the cartridge compartment is integrally formed with a downwardly protruding mounting groove, and the atomizer is disposed in the mounting groove; the bottom of the mounting groove is provided with a vent hole penetrating its wall, for guiding the airflow of the first air intake path to the atomizer.

[0009] Preferably, the cartridge compartment is provided with a baffle for guiding and holding the e-liquid near the atomizer.

[0010] Preferably, the cross-sectional area of ​​the first air intake path is larger than the cross-sectional area of ​​the airflow sensing channel.

[0011] Preferably, the enclosure is made of silicone.

[0012] Preferably, the side wall of the cartridge compartment is provided with an oil inlet, and the oil inlet is provided with a sealing cap for opening or closing it.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention successfully achieves the simultaneous fulfillment of main airflow supply and airflow sensing requirements by setting a common air inlet and cooperating with an integrated airflow structure including a parallel first air inlet path and an airflow sensing channel. This completely eliminates the need for a dedicated sensing air hole at the bottom of the device from a physical structural perspective, eradicating the risk of oil leakage caused by bottom openings and resolving the inherent contradiction in the prior art of balancing "oil leakage prevention" and "automatic triggering." Furthermore, the first air inlet path is specifically configured to include a buffer channel and a deflection channel. This unique non-linear path design not only achieves high-level air intake, but more importantly, by extending the path and changing the airflow direction, it significantly increases the resistance and difficulty of liquid e-liquid or condensate permeating outwards, forming an oil leakage prevention barrier together with the air inlet.

The first air inlet path 5 is configured such that, starting from its connection with the air inlet, its airflow path first extends for a predetermined length along a predetermined path different from the direction of direct entry into the atomizer 3 to form a buffer channel 52, and then changes direction via a turning channel 51 before leading to the atomizer 3. The triggering mechanism includes the airflow sensor 60 and a manual button 1 disposed on the main body; The airflow through the airflow sensing channel 6 can trigger the airflow sensor 60 to make the atomizer 3 work, and the manual button 1 is configured to trigger the atomizer 3 independently of the airflow sensor 60.

[0022] Furthermore, the main body includes an upper housing 81 and a lower housing 82 connected to each other. The airflow sensor 60 is disposed at the end of the airflow sensing channel 6 and is used to detect the airflow flowing into the airflow sensing channel 6. The main body is provided with a movable cover plate 7, which is used to open or close the air inlet.

[0023] Furthermore, the lower housing 82 includes a first outer shell 821 and a second outer shell 822 that are detachably connected. A control board 8210 is provided on the first outer shell 821, and a power supply 8220 is provided on the second outer shell 822. A pin 823 and a socket 8230 are correspondingly provided on the mating surfaces of the first outer shell 821 and the second outer shell 822. The control board 8210 and the power supply 8220 are electrically connected by inserting the pin 823 into the socket 8230.

[0024] Furthermore, the first outer shell 821 is provided with a guide post 9, and the upper and lower ends of the second outer shell 822 are provided with clamping parts 90; the two ends of the guide post 9 are respectively assembled into the corresponding clamping parts 90 to achieve preliminary positioning; the lower ends of the first outer shell 821 and the second outer shell 822 are covered by a base plate 91, and the base plate 91 is provided with a through hole corresponding to the position of the clamping part 90. The screw 92 passes through the through hole and is threaded to the end of the guide post 9, thereby realizing the connection and fixation of the first outer shell 821, the second outer shell 822 and the base plate 91.

[0025] Furthermore, the bottom of the cartridge compartment 2 is integrally formed with a downwardly protruding mounting groove 21, and the atomizer 3 is disposed in the mounting groove 21; the bottom of the mounting groove 21 is provided with a vent hole 22 that penetrates its wall, which is used to guide the airflow of the first air intake path 5 to the atomizer 3.

[0026] Furthermore, the cartridge compartment 2 is provided with a baffle 31 for guiding and holding the e-liquid near the atomizer 3.

[0027] Furthermore, the cross-sectional area of ​​the first air intake path 5 is larger than the cross-sectional area of ​​the airflow sensing channel 6.

[0028] Furthermore, the enclosure part 31 is made of silicone.

[0029] Furthermore, the side wall of the cartridge compartment 2 is provided with an oil inlet 20, and the oil inlet 20 is provided with a sealing cap 201 for opening or closing it.

[0030] The working principle of this utility model is as follows: As an embodiment 1, the electronic cigarette of this application includes a main body and a button 1 disposed on the main body. The main body has a cartridge compartment 2 for storing e-liquid, and an atomizer 3 is disposed in the cartridge compartment 2. An inhalation nozzle 4 communicating with the atomizer 3 is disposed at the top of the main body. This application provides a first air intake path 5 and an airflow sensing channel 6 connected in parallel within the main body, and the air intake is opened or closed by a movable cover 7.

[0031] When the cover 7 opens the air intake, the first air intake path 5 connects to the outside, such as... Figure 3 As shown in the diagram, the user inhales through the inhaler 4. Part of the external air enters the atomizer 3 through the first air intake path 5, while the other part of the air is diverted to the airflow sensing channel 6. The airflow sensor 60 in the airflow sensing channel 6 detects the airflow, generates a signal, and triggers the atomizer 3 to work, producing vapor. At the same time, the user can also manually trigger the atomizer 3 to work by pressing the button 1.

[0032] Based on the above technical solution, the main body of this application is formed by connecting an upper shell 81 and a lower shell 82 with screws, as follows: Figure 3 As shown, the air inlet is located on the side wall of the upper housing 81, and its internal channel is constructed as a turning channel 51 with at least one directional bend (e.g., an L-shaped channel). The "L-shaped" or similar bend structure of the turning channel 51 constitutes a crucial physical barrier. When the e-cigarette is not upright or is subjected to shaking or internal pressure fluctuations, even if a small amount of liquid e-liquid enters the turning channel 51, the liquid substance must overcome the additional resistance caused by the abrupt change in the direction of the flow path (including but not limited to the effects of liquid surface tension, adhesion, and gravity changes) in order to continue migrating to the external atmosphere. Therefore, the turning channel 51, through its non-linear geometric path, effectively interrupts the possible straight-through leakage path between the inside of the atomizer 3 and the external environment, significantly increasing the difficulty of accidental leakage of e-liquid from the air inlet path.

[0033] Based on the above technical solution, the working principle of the airflow sensing channel 6 in this application is as follows: The user inhales through the inhalation nozzle 4. Part of the external air enters the atomizer 3 through the first air intake path 5, while the other part is diverted to the airflow sensing channel 6. Since the end of the airflow sensing channel 6 is closed, the inflowing gas only causes changes in pressure or flow rate within the channel, which are detected by the airflow sensor 60 at the end, thereby triggering the atomizer 3 to operate. The detected gas does not flow towards the atomizer but returns essentially along the same path after inhalation stops. Preferably, the cross-sectional area of ​​the first air intake path 5 is larger than the cross-sectional area of ​​the airflow sensing channel 6.

[0034] Based on the above technical solution, the structural fit of the lower housing 82 can be as follows: the lower housing 82 is composed of a first outer shell 821 and a second outer shell 822 connected by a detachable structure. A control board 8210 is housed inside the first outer shell 821, and a power supply 8220 is housed inside the second outer shell 822. To facilitate assembly and circuit connection, pins 823 and sockets 8230 are respectively provided on the mating surfaces of the first outer shell 821 and the second outer shell 822. During assembly, the pins 823 are inserted into the sockets 8230 to achieve electrical connection between the control board 8210 and the power supply 8220, eliminating the need for additional wire soldering and making assembly convenient and reliable. Furthermore, a guide post 9 is provided on the first outer shell 821, and clamping parts 90 are provided at both the upper and lower ends of the second outer shell 822. During assembly, the two ends of the guide post 9 are first engaged with the clamping parts 90 to achieve initial positioning and fixation. Finally, a separate base plate 91 covers the lower ends of the first housing 821 and the second housing 822. Screws 92 pass through the through holes on the base plate 91 and are screwed into the threaded holes at the ends of the guide posts 9, thereby tightly connecting and fixing the first housing 821, the second housing 822 and the base plate 91 together.

[0035] Based on the above technical solution, the installation and assembly of the cartridge 2 can be as follows: the bottom of the cartridge 2 has an integrally formed downward recessed mounting groove 21, and the lower end of the atomizer 3 is installed in the mounting groove 21. A vent 22 is provided at the bottom of the mounting groove 21 to guide the airflow after the first air intake path 5 and the airflow sensing channel 6 converge to the atomizer 3, promoting e-liquid atomization. The cartridge 2 also has a silicone baffle 31 that surrounds the atomizer 3, guiding and concentrating the e-liquid near the atomizer 3, ensuring a continuous and sufficient supply of e-liquid, effectively preventing dry burning of the atomizer 3 due to e-liquid diffusion, and improving atomization efficiency and component lifespan. An e-liquid inlet 20 is provided on the side wall of the cartridge 2, and a sealing cap 201 is provided on the inlet 20, allowing for easy opening or closing of the inlet 20 for convenient e-liquid refilling.

[0036] This invention, by setting a common air inlet and cooperating with an integrated air path structure including a parallel first air inlet path 5 and an airflow sensing channel 6, successfully achieves the simultaneous fulfillment of the main airflow supply and airflow sensing requirements by a single high-position air inlet. This completely eliminates the need for a dedicated sensing air hole at the bottom of the device from a physical structural perspective, eradicating the risk of oil leakage caused by bottom openings and resolving the inherent contradiction in the prior art of balancing "oil leakage prevention" and "automatic triggering." Furthermore, the first air inlet path 5 is specifically configured to include a buffer channel 52 and a turning channel 51. This unique non-linear path design not only achieves high-position air intake, but more importantly, by extending the path and changing the airflow direction, it significantly increases the resistance and difficulty of liquid e-liquid or condensate permeating outwards, forming an oil leakage prevention barrier together with the air inlet.

[0037] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
