Description

Technical Field

[0001] This utility model relates to the field of electronic atomization equipment technology, and in particular to an oil core separation and power-off leak prevention device. Background Technology

[0002] Electronic atomizing devices, commonly known as e-cigarettes, are experiencing rapid market growth as an alternative to traditional cigarettes. However, existing technologies for electronic atomizing devices generally suffer from two main problems: first, leakage, especially during transportation, carrying, or when not in use, where the atomizing liquid may seep out from the tank or inlet, affecting the user experience and causing waste; second, safety issues, as the device may be accidentally activated due to unintended contact, leading to the dry burning of the atomizer coil or continuous operation without supervision, posing a safety hazard.

[0003] Currently, methods for addressing oil leakage issues typically include optimizing sealing rings and improving oil tank structures, but these methods have limited effectiveness and fail to completely eliminate leakage during non-use periods. Regarding safety, electronic lock solutions such as "pressing the power button five times consecutively" are commonly used, but these are relatively cumbersome and do not solve the physical oil leakage problem. Finding a simple, intuitive, and reliable method to simultaneously address both oil leakage during non-use periods and accidental start-ups is a pressing technical challenge in this field. Utility Model Content

[0004] The purpose of this invention is to provide an oil-wick separation and power-off leak-proof device, which aims to solve the technical problems of existing electronic atomizing devices being prone to oil leakage and accidental activation when not in use.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An oil-wick separation and power-off leak-proof device, characterized in that it comprises:

[0007] Shell (1);

[0008] The upper bracket (2) is fixedly installed inside the housing (1). The upper bracket (2) has a second oil tank (21) and a second through hole (22) on its inner side.

[0009] Silicone component (3) is disposed on the upper bracket (2);

[0010] The atomizing core assembly (4) is slidably disposed inside the housing (1). The side wall of the atomizing core assembly (4) is provided with an oil inlet hole (41), and an electrode (42) is provided at its bottom.

[0011] A spring pin (5) is disposed at the bottom of the housing (1);

[0012] The atomizing core assembly (4) has a first position and a second position. When the atomizing core assembly (4) is in the first position, its oil inlet (41) is connected to the second through hole (22), and its electrode (42) is electrically connected to the spring needle (5). When the atomizing core assembly (4) is in the second position, its oil inlet (41) is attached to and closed by the silicone part (3), and its electrode (42) is disconnected from the spring needle (5).

[0013] Preferably, it further includes:

[0014] A suction nozzle (6) is fitted over the housing (1);

[0015] A connecting bracket (7) is fixedly connected at one end to the mouthpiece (6) and at the other end to the top of the atomizing core assembly (4);

[0016] By lifting or pressing the mouthpiece (6), the atomizing core assembly (4) is moved between the first position and the second position.

[0017] Preferably, a limiting groove (11) is provided inside the housing (1);

[0018] The connecting bracket (7) has outwardly forming limiting edges (71) on both sides. The size of the limiting edges (71) is larger than the size of the limiting groove (11). The limiting edges (71) cooperate with the limiting groove (11) to limit the stroke of the atomizing core assembly (4) moving upward to the second position.

[0019] Preferably, the upper support (2) is a three-dimensional ring structure, and the upper support (2) is fixed inside the housing (1) to separate the first oil tank located above it.

[0020] Preferably, the upper support (2) has a first through hole (23) on its upper side, and the first oil tank is connected to the second oil tank (21) through the first through hole (23).

[0021] Preferably, the silicone part (3) is fitted along the edge of the first through hole (23).

[0022] Preferably, the first position is the position where the atomizing core assembly (4) slides down until its electrode (42) contacts the spring needle (5).

[0023] Preferably, the second position is the position where the atomizing core assembly (4) slides upward until its oil inlet (41) is blocked by the silicone part (3).

[0024] By adopting the above technical solution, this utility model features a sliding atomizing core assembly with two working positions. In the first position (working state), the oil circuit and electrical circuit are simultaneously connected, allowing the device to operate normally. In the second position (locked state), the oil inlet of the atomizing core assembly is physically sealed by a silicone component, completely eliminating the possibility of oil leakage. Simultaneously, the electrode at the bottom separates from the spring pin, cutting off the power supply to the entire device. Users can achieve simultaneous "locking" and "unlocking" of the oil circuit and electrical circuit with a simple up-and-down pushing and pulling action. The operation is intuitive and convenient, the structure is reliable, and it greatly improves the product's safety and leak-proof performance. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0033] Please see Figure 1 and Figure 2 This utility model provides an oil core separation power-off and oil leakage prevention device, including a housing (1), an upper bracket (2), a silicone part (3), an atomizing core assembly (4), and a spring needle (5).

[0034] The housing (1) provides a mounting base and external outline for the entire device, and its material can be metal, plastic, or ceramic. In this embodiment, the interior of the housing (1) houses all the core components of the device.

[0035] The upper bracket (2) is fixedly disposed inside the housing (1). This "fixed disposal" can be achieved in various ways. For example, the upper bracket (2) can be connected to the inner wall of the housing (1) by threads, snap-fit, or interference fit. In this preferred embodiment, the upper bracket (2) and the housing (1) are integrally injection molded, resulting in better structural stability. The upper bracket (2) is a three-dimensional annular structure that divides the internal space of the housing (1) into a first oil tank (used to store most of the atomizing liquid) located above it and a second oil tank (21) located inside its annular structure. One or more first through holes (23) are provided on the upper side of the upper bracket (2), allowing the atomizing liquid in the first oil tank to flow into the second oil tank (21) by gravity. One or more second through holes (22) are provided on the inner wall of the upper bracket (2), which are channels for the atomizing liquid to enter the atomizing core assembly (4) from the second oil tank (21).

[0036] The silicone part (3) is an elastic sealing component. In this embodiment, it is preferably integrally formed or bonded to the upper surface of the upper bracket (2) and precisely fitted around the edge of the first through hole (23). When the atomizing core assembly (4) moves upward, its sidewall will fit tightly against the silicone part (3).

[0037] The atomizing core assembly (4) is the core component of the device. It integrates the heating wire, oil-guiding cotton, etc., and can slide vertically up and down within the housing (1). An oil inlet (41) is provided on the side wall of the atomizing core assembly (4) to absorb the atomized liquid from the second through-hole (22). At its bottom, a conductive electrode (42) is provided, which is connected to the heating circuit inside the atomizing core.

[0038] The spring needle (5) is fixedly installed at the bottom of the housing (1) and serves as the positive or negative contact of the device. The spring needle (5) itself has a certain amount of elastic extension and contraction to ensure good contact with the electrode (42) at the bottom of the atomizing core assembly (4).

[0039] Working principle explanation:

[0040] The core of this device lies in the two switchable positions of the atomizing core assembly (4).

[0041] First position (working status), as shown in the attached image. Figure 1As shown: When the user presses the atomizer core assembly (4) down to the bottom, it is in the first position. At this time, the oil inlet (41) of the atomizer core assembly (4) is aligned and connected with the second through hole (22) on the inner side of the upper bracket (2) in terms of height, and the atomized liquid in the second oil tank (21) can flow smoothly into the atomizer core assembly (4) and be absorbed by the oil-guiding cotton. At the same time, the electrode (42) at the bottom of the atomizer core assembly (4) moves downward and contacts the spring pin (5) at the bottom of the housing (1) to form a stable electrical connection. At this time, both the oil circuit and the electrical circuit are in a conductive state, and the user can vape normally.

[0042] Second position (locked state), as shown in the attached image. Figure 2 As shown: When the user pulls the atomizer core assembly (4) upward to its highest point, it is in the second position. During this process, the atomizer core assembly (4) moves upward as a whole. Its oil inlet (41) moves upward accordingly, disaligning with the second through hole (22), and is finally completely covered and tightly fitted by the silicone part (3) above the upper bracket (2). The elastic deformation of the silicone part (3) can achieve a physical and reliable seal on the oil inlet (41), thereby completely blocking the oil path. At the same time, as the atomizer core assembly (4) moves upward, its bottom electrode (42) also moves away from the spring pin (5) at the bottom of the housing (1), and the physical contact between the two is broken, thereby cutting off the power supply circuit of the entire device. At this time, both the oil path and the electrical circuit are disconnected, the device cannot work and will not leak oil.

[0043] Further preferred embodiments:

[0044] To facilitate the user's operation of the up and down movement of the atomizing core assembly (4), the device further includes a mouthpiece (6) and a connecting bracket (7).

[0045] The nozzle (6) is fitted onto the top of the housing (1) and is the part that the user directly contacts. This "fitting" can be a snap-fit ​​or threaded connection for easy disassembly and cleaning. The connecting bracket (7), as a transmission component, is fixedly connected to the nozzle (6) at its upper end by injection molding, bonding, or snap-fit, and its lower end is firmly connected to the top of the atomizing core assembly (4). Thus, by directly lifting or pressing the nozzle (6), the user can precisely switch the atomizing core assembly (4) between the first and second positions via the transmission of the connecting bracket (7), making operation extremely convenient.

[0046] To ensure more precise and stable travel of the atomizing core assembly (4), this device also incorporates a limiting structure. Specifically, an annular limiting groove (11) is provided at the upper inner end of the housing (1). Correspondingly, limiting edges (71) are integrally formed or additionally installed on both sides of the connecting bracket (7). The outer diameter of the limiting edge (71) is larger than the inner diameter of the limiting groove (11). When the user pulls the mouthpiece (6) upward, the connecting bracket (7) drives the atomizing core assembly (4) upward. When the lower surface of the limiting edge (71) abuts against the upper surface of the limiting groove (11), the upward travel is terminated, ensuring that the atomizing core assembly (4) stops precisely at the second position. The downward travel is naturally limited by the position where the electrode (42) of the atomizing core assembly (4) contacts the spring needle (5), ensuring that it stops precisely at the first position.

[0047] In summary, this utility model, through ingenious mechanical linkage design, integrates the functions of oil circuit blocking and circuit disconnection into a single, linear user action. It has a simple and reliable structure, is easy to use, and effectively solves the problems of oil leakage and accidental start-up of electronic atomizing devices, thus possessing high practical value.

[0048] 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. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
