Description

Technical Field

[0001] This application relates to the field of electronic cigarettes, and in particular to a hygienic e-cigarette with a clear oil coating. Background Technology

[0002] In existing e-cigarette technology, the dust cover design primarily aims to physically block external dust, but its functionality has a fundamental flaw. When the user closes the dust cover, although it can prevent most external contaminants from contacting the mouthpiece or device casing, the oil passage between the oil tank and the cartridge remains open. This design severs the connection between dust prevention and oil passage control—the dust cover exists only as an external covering component and fails to trigger a physical seal of the oil passage interface. Therefore, in non-use conditions, the oil outlet of the oil tank and the oil inlet of the cartridge remain connected, causing continuous leakage in high-temperature environments due to reduced e-liquid viscosity and increased fluidity, or passive leakage in low-pressure environments (such as air transport) due to the pressure difference between the inside and outside of the oil tank exceeding the sealing threshold. The direct consequence of this leakage is that e-liquid seeps out through the unsealed oil passage, contaminating the internal circuitry and external surfaces of the device. Simultaneously, the exposed oil accelerates oxidation and deterioration, further affecting atomization quality. Utility Model Content

[0003] The purpose of this application is to overcome at least one deficiency of the prior art and to provide a hygienic, clear oil electronic cigarette.

[0004] To achieve the above objectives, this application discloses a hygienic e-cigarette with an e-liquid reservoir, including a body having an e-liquid reservoir, an e-liquid cartridge installed in the body, and a cover that can be opened and closed to the body.

[0005] The main body has a longitudinally extending mounting cavity inside, and the side wall of the mounting cavity has an oil outlet channel communicating with the oil tank; the e-cigarette cartridge is axially floating in the mounting cavity, and its outer peripheral surface forms a sliding fit with the inner wall of the mounting cavity, and provides an upward reset force through an elastic reset element.

[0006] The side wall of the cartridge is provided with an oil inlet channel corresponding to the oil outlet channel of the mounting cavity. The oil inlet channel is connected to the atomizing component in the cartridge through an internal oil guiding medium.

[0007] When the cover closes to the body, the cover drives the cartridge to move downward along the axial direction of the mounting cavity, causing the oil inlet channel and the oil outlet channel to be radially misaligned, thus achieving physical isolation of the oil circuit; when the cover is opened, the elastic reset element pushes the cartridge upward to reset, so that the oil inlet channel and the oil outlet channel are axially aligned and connected, forming an oil transport path.

[0008] Furthermore, the mounting cavity is provided with a guide limiting structure, including an axially extending guide rail and a cooperating guide groove, which is used to constrain the radial displacement of the cartridge and ensure the linearity of its axial movement.

[0009] Furthermore, the elastic reset element is preferably a compression spring, with its two ends abutting against the bottom of the cartridge and the bottom wall of the mounting cavity, respectively, to provide axial reset force for the cartridge.

[0010] Furthermore, the cover is hinged to the body.

[0011] Furthermore, a locking mechanism is provided between the cover and the body, including a buckle protrusion on the edge of the cover and a corresponding slot on the body. When the cover is closed, the buckle protrusion and the slot form an elastic engagement to ensure the positional stability of the cover.

[0012] Furthermore, the cartridges are detachably installed within the mounting cavity, making them replaceable.

[0013] Furthermore, the oil-conducting medium is a porous oil-absorbing cotton core that penetrates the interior of the cartridge and tightly fits the oil inlet channel with the surface of the heating element of the atomizing component, thereby achieving capillary delivery and uniform penetration of the oil.

[0014] Furthermore, the body contains a battery and a control circuit connected to the battery; the atomizing component is substantially electrically connected to the battery and the control circuit.

[0015] Furthermore, the oil tank of the main body has an observation window for observing the oil level.

[0016] Compared with the prior art, this application achieves physical isolation of the oil circuit by closing the cover, which effectively solves the oil leakage problem caused by the inability of the dust cover to cut off the oil circuit in the prior art, avoids the leakage of e-liquid from contaminating the equipment and accelerating oxidation and deterioration, and improves the sealing performance and atomization quality of the equipment.

[0025] See attached document Figure 1 and 2 In a specific embodiment of this utility model, the overall structure of the hygienic e-cigarette consists of a body 1, a cartridge 2, a cover 3, and related mating parts. Each component achieves its function through specific connections and mating relationships. Specifically, in this embodiment, the body 1 serves as the basic structure of the e-cigarette, and has a longitudinally extending mounting cavity 101 inside. The side wall of the mounting cavity 101 has an oil outlet channel 103 communicating with the oil tank 102. The cartridge 2 is axially floatingly disposed within the mounting cavity 101, and its outer circumferential surface forms a sliding fit with the inner wall of the mounting cavity 101. This fit ensures the smoothness of the cartridge 2 during axial movement. To enable the cartridge 2 to automatically reset, the body 1 also has an elastic reset element 104, such as a compression spring, whose two ends abut against the bottom of the cartridge 2 and the bottom wall of the mounting cavity 101, respectively, providing a stable upward preload force, i.e., a reset elastic force, to the cartridge 2.

[0026] The side wall of the cartridge 2 is provided with an oil inlet channel 201 corresponding to the oil outlet channel 103 of the mounting cavity 101. The oil inlet channel 201 is connected to the atomizing component 202 inside the cartridge 2, such as the atomizing core, through an internal oil guiding medium, such as a porous oil-absorbing cotton core.

[0027] A porous absorbent cotton core runs through the interior of the e-liquid cartridge 2, with one end tightly fitted to the oil inlet channel 201 and the other end tightly fitted to the surface of the heating element of the atomizing component 202. It utilizes capillary action to achieve oil delivery and uniform penetration, ensuring a stable and even supply of e-liquid to the atomizing component 202. This design of the oil-conducting medium is well-known to those skilled in the art, and its purpose is to improve the e-liquid delivery efficiency and atomization effect.

[0028] The cover 3 is closable to the body 1, and its closing action is key to achieving oil circuit isolation. When the cover 3 closes to the body 1, it drives the cartridge 2 to move downwards along the mounting cavity 101, causing the oil inlet channel 201 and the oil outlet channel 103 to form a misaligned fit, thereby achieving physical isolation of the oil circuit and effectively preventing e-liquid leakage when not in use. When the cover 3 is open, the elastic reset element 104 pushes the cartridge 2 upwards to reset, aligning the oil inlet channel 201 and the oil outlet channel 103 to form an oil delivery path, ensuring that the e-liquid can be normally delivered to the atomizing component 202 for atomization.

[0029] To ensure the stability and straightness of the cartridge 2 during axial movement, the mounting cavity 101 is provided with a guide limiting structure, such as a guide rail extending along the axial direction and a guide groove that cooperates with it, to constrain the radial displacement of the cartridge 2.

[0030] More specifically, in this embodiment, the connection between the cover 3 and the body 1 is a hinged installation, which facilitates the opening and closing of the cover. Furthermore, as a preferred embodiment, a locking mechanism is provided between the cover 3 and the body 1, such as a buckle protrusion on the edge of the cover and a corresponding slot on the body. When the cover 3 is closed, the buckle protrusion and the slot form an elastic engagement, ensuring the positional stability of the cover 3 and preventing accidental opening during transport.

[0031] Based on the above structure, the tobacco cartridge 2 adopts a detachable installation method and is installed in the installation cavity 101, so that the tobacco cartridge 2 can be replaced, making it convenient for users to replace different types of tobacco cartridge 2 according to their personal taste or needs.

[0032] As a standard and necessary design, the main body 1 also includes a battery and a control circuit connected to the battery. The atomizing component 202 is substantially electrically connected to the battery and the control circuit, providing stable power support for the atomizing component 202. It should be noted that the specific structure and connection method of the battery and the control circuit are well-known and existing technologies to those skilled in the art, and do not need to be disclosed in detail.

[0033] In a preferred embodiment, the e-liquid reservoir 102 of the main body 1 is also provided with an observation window for observing the e-liquid level, such as a window made of transparent material, so that the user can easily see the remaining e-liquid level and replenish or replace it in a timely manner. This design is quite common in the field of electronic cigarettes and is part of the prior art.

[0034] In practical use scenarios, such as when a user is using an e-cigarette daily, opening the cover 3 causes the cartridge 2 to return to its original position via the elastic reset element 104. This aligns the oil inlet channel 201 with the oil outlet channel 103, opening the oil path. E-liquid is then transported to the atomizing component 202 through the oil guide medium for atomization, allowing the user to use the e-cigarette normally. In non-use situations, such as when the e-cigarette is placed in a high-temperature environment or during air transport, closing the cover 3 causes the cartridge 2 to descend, misaligning the oil inlet channel 201 with the oil outlet channel 103. This physically isolates the oil path, effectively preventing leakage due to high temperature or pressure difference, protecting the internal circuitry and external surfaces from contamination, and preventing accelerated oxidation and deterioration of the e-liquid, thus ensuring the stability of atomization quality and the reliability of the device.

[0035] Compared to traditional open-oil e-cigarettes, which only use a dust cover to block external dust but cannot cut off the oil supply, this design offers significant improvements and advantages, providing users with a more hygienic and reliable e-cigarette experience.

[0036] While exemplary embodiments of this disclosure have been described, those skilled in the art will understand that various changes and modifications can be made to the exemplary embodiments of this disclosure without departing from the spirit and scope thereof. Therefore, all changes and modifications are included within the scope of protection of this disclosure as defined by the claims. This disclosure is defined by the appended claims, and equivalents of those claims are also included.
