Description

Technical Field

[0001] This utility model relates to the field of electronic atomization equipment technology, and in particular to an electronic atomizer with multiple leak-proof structures. Background Technology

[0002] As a smoking cessation product, the user experience of electronic atomizers (commonly known as e-cigarettes) is of paramount importance. However, leakage has always been the biggest pain point plaguing the industry, severely impacting the user experience.

[0003] Once oil leakage occurs, the e-liquid will contaminate the equipment and the environment, causing great inconvenience to users.

[0004] Many electronic atomizers on the market currently use a bottom spring air intake or a similar bottom air intake method. With this design, the air intake is located at the bottom of the device. During use, condensate produced by the atomizer coil or slight e-liquid leakage can easily flow out of the bottom air intake under gravity, causing leakage.

[0005] Furthermore, most top-filling e-liquid systems on the market use a screw-on cap seal. When the user tightens the cap, the rotation of the cap compresses the air inside the e-liquid tank, causing a sudden increase in internal pressure. This positive pressure forces the e-liquid into the atomizer coil, leading to oversaturation and causing issues such as "choking on e-liquid," "gurgling sounds," or leakage from the bottom, all of which negatively impact the user experience.

[0006] Therefore, there is an urgent need for a technical solution that can systematically address the oil leakage problem from multiple dimensions. Utility Model Content

[0007] The purpose of this invention is to provide an electronic atomizer with multiple leak-proof structures, aiming to systematically solve the oil leakage problem caused by various reasons such as bottom air intake and changes in oil injection pressure in the prior art.

[0008] An electronic atomizer with multiple leak-proof structures, characterized in that it comprises:

[0009] A shell;

[0010] An oil tank is disposed within the housing;

[0011] And an atomizing core disposed within the oil tank;

[0012] An intake assembly, the intake assembly comprising:

[0013] An air inlet is provided on the side wall of the housing, and the position of the air inlet is higher than the bottom of the atomizing core;

[0014] And an airflow channel defined within the housing, the airflow channel being configured to guide air from the air inlet to the bottom of the atomizing core and to allow air to enter the interior of the atomizing core;

[0015] An oil injection assembly, the oil injection assembly comprising:

[0016] An injection port communicating with the oil reservoir;

[0017] And a top cover disposed on the top of the housing, the top cover being configured to slide transversely on the housing to selectively open or close the injection port, wherein the top cover does not substantially change the internal volume of the oil reservoir during the process of closing the injection port;

[0018] And a leak-proof component, which is at least one oil-absorbing cotton disposed at the bottom of the housing and located below the atomizing core.

[0019] Preferably, the intake assembly further includes an intake adjustment mechanism, the intake adjustment mechanism comprising:

[0020] A sliding groove defined on the outer wall of the housing;

[0021] A push button, the push button being slidably disposed within the sliding groove;

[0022] An air regulating block is disposed within the airflow channel and embedded in the push knob for coordinated operation;

[0023] And an air-regulating silicone, which is attached to the air-regulating block and elastically contacts the inner wall of the airflow channel. By sliding the push knob to move the air-regulating block and the air-regulating silicone within the airflow channel, the cross-sectional area of ​​the airflow channel can be changed to adjust the airflow rate.

[0024] Preferably, the airflow channel is defined between the outer wall of the atomizing core and the inner wall of the housing.

[0025] Preferably, the airflow channel further includes a converging cavity surrounding the bottom of the atomizing core, the converging cavity being used to collect the air flowing down from the airflow channel and guide it to the air inlet at the bottom of the atomizing core.

[0026] Preferably, the oil injection assembly further includes a fixed top cover, which is fixedly sealed to the top of the oil tank and has the injection hole; the top cover is slidably installed above the fixed top cover and is pressed and sealed to the injection hole when closed by a sealing element.

[0027] Preferably, the electronic atomizer further includes a base defining an internal groove for mounting the absorbent cotton; the atomizing coil is inserted and mounted on the base, and an electrode passes through the base to be electrically connected to the atomizing coil, the absorbent cotton surrounding the peripheral area of ​​the electrode.

[0028] Preferably, there are two oil-absorbing cotton pieces, which are symmetrically arranged in the internal groove of the base and located on both sides of the electrode.

[0029] Preferably, the atomizing core has an integrated external structure.

[0030] Compared with the prior art, the present invention, through the above technical solution, has at least the following beneficial effects:

[0031] By adopting an "upper air intake" structure (the air intake hole is higher than the bottom of the atomizer core), even if there is condensate or oil seepage at the bottom, it cannot defy the laws of physics and "climb up" to the air intake hole to flow out, thus completely eliminating the risk of oil leakage from the bottom air intake structure.

[0032] By employing a "sliding" top cap for e-liquid filling, the process of filling and closing the top cap involves only a sliding motion, without compressing the e-liquid tank volume, thus maintaining a stable air pressure inside the tank. This effectively avoids the choking and leakage caused by pressure changes forcing e-liquid into the atomizer coil.

[0033] An additional absorbent cotton layer is placed at the bottom of the atomizer coil as a "last line of defense." Even in extreme cases (such as when the atomizer coil is damaged and e-liquid seeps down), this absorbent cotton layer can absorb and trap it, preventing e-liquid from contacting the bottom electrode or leaking out from the device's gaps, thus providing double protection.

[0043] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings and reference numerals in the embodiments of the present invention.

[0044] Please see Figures 1 to 4This utility model provides an electronic atomizer. The electronic atomizer includes a housing 10 and an oil reservoir 12 disposed within the housing 10. Figure 2 and Figure 3 It consists of components such as the outer structure 141 of the core and the inner wall of the shell 10, as well as an atomizing core 14 disposed in the oil tank 12.

[0045] The core of this utility model lies in its multiple leak-proof structures:

[0046] Intake assembly 20 (for resolving oil leaks during daily use): Please refer to [link / reference]. Figure 2 and Figure 3 The air intake assembly 20 includes an air intake port 21 disposed on the side wall of the housing 10. From Figure 3 The cross-sectional structure clearly shows that the air inlet 21 is physically positioned higher than the bottom of the atomizing core 14. Simultaneously, an airflow channel 22 is defined within the housing 10. Air enters through the air inlet 21, is guided downwards along the airflow channel 22, and eventually reaches the bottom of the atomizing core 14, entering the interior of the atomizing core 14 through the atomizing core air inlet 142.

[0047] Lubrication assembly 30 (for resolving oil leakage due to injection pressure): Please refer to... Figure 2 and Figure 3 The oil injection assembly 30 includes an injection port 31 communicating with the oil reservoir 12. The oil injection assembly 30 also includes a top cover 32 (i.e., a sliding cover) disposed on the top of the housing 10. Figure 3 As shown, the top cover 32 is configured to slide translationally on the housing 10 to open or close the injection port 31. During the closing of the injection port 31, the translational movement of the top cover 32 does not substantially change the internal volume of the oil tank 12, thereby preventing an increase in the internal pressure.

[0048] Leak-proof component 40 (for solving oil leaks in extreme situations): Please refer to Figure 2 and Figure 3 The leak-proof component 40 is specifically at least one oil-absorbing cotton 41. The oil-absorbing cotton 41 is disposed at the bottom of the housing 10 and below the atomizing core 14, serving as the last line of defense against leaks.

[0049] Please see Figure 2 and Figure 3 In one specific implementation, the air intake assembly 20 further includes an air intake adjustment mechanism 23.

[0050] The intake adjustment mechanism 23 includes a sliding groove 231 defined on the outer wall of the housing 10.

[0051] A push-button 232 (e.g.) Figure 1 The exposed portion shown is slidably disposed within the sliding groove 231.

[0052] An air regulating block 233 is disposed in the airflow channel 22 and embedded in the push knob 232 so as to slide together with the push knob 232.

[0053] An air-regulating silicone 234 is attached to the air-regulating block 233 and elastically contacts the inner wall of the airflow channel 22 to form a seal.

[0054] Working principle: By sliding the push knob 232, the user moves the air regulating block 233 and the air regulating silicone 234 within the airflow channel 22, thereby changing the cross-sectional area of ​​the airflow channel 22 and adjusting the airflow.

[0055] To further define the airflow channel 22, please refer to Figure 2 and 3 In a preferred embodiment, the airflow channel 22 is specifically defined between the outer wall of the atomizing core 14 and the inner wall of the housing 10.

[0056] As a preferred option, please refer to [the relevant documentation / reference]. Figure 3 The airflow channel 22 further includes a confluence chamber 24 upon reaching the bottom of the atomizing core 14. This confluence chamber 24 is located around and surrounds the bottom of the atomizing core 14. Its function is to collect the air flowing down from the airflow channel 22 and guide it evenly to the atomizing core air inlet 142.

[0057] Please see Figure 2 and Figure 3 The installation structure of the oil injection component 30 will be described in detail.

[0058] The oil injection assembly 30 also includes a fixed top cover 33. The fixed top cover 33 is fixedly sealed to the top of the oil tank 12 and has the injection hole 31.

[0059] The top cover 32 (sliding cover) is slidably mounted above the fixed top cover 33.

[0060] A sealing element 34 (e.g., sealing silicone) is provided on the bottom surface of the top cover 32. When the top cover 32 is slid to the closed position, the sealing element 34 elastically presses against the opening of the injection hole 31 on the fixed top cover 33 to achieve a seal.

[0061] Please see Figure 2 and Figure 3 The installation structure of the leak-proof component 40 will be described in detail.

[0062] The electronic atomizer also includes a base 50.

[0063] The base 50 defines an internal groove 51 for mounting the oil-absorbing cotton 41.

[0064] The atomizing core 14 is inserted and installed on the base 50.

[0065] An electrode 52 (e.g.) Figure 4 (As shown) Passes through the central through hole of the base 50 to be electrically connected to the bottom of the atomizing core 14.

[0066] The oil-absorbing cotton 41 is installed in the internal groove 51 and surrounds the peripheral area of ​​the electrode 52.

[0067] Please see Figure 3 and Figure 4 Preferably, there are two pieces of oil-absorbing cotton 41.

[0068] The two oil-absorbing cotton pieces 41 are symmetrically arranged in the internal groove 51 of the base 50 and are located on both sides of the central electrode 52.

[0069] Please see Figure 2 and Figure 3 As a preferred embodiment, the atomizing core 14 has an integrated external structure, namely... Figure 3 The outer structure 141 of the core is shown.

[0070] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
