Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to a heated non-combustible aerosol generating device. Background Technology

[0002] In the field of e-cigarette technology, traditional combustion tobacco products produce harmful substances such as tar and carbon monoxide due to high-temperature combustion, posing a threat to the health of users. Early e-cigarette products mostly adopted simple heating and atomization structures, which had problems such as uneven heating, low atomization efficiency, and rough aerosol taste. Therefore, there is a particular need for a heat-not-burn aerosol generating device.

[0003] A search revealed Chinese patent CN222284689U, published on January 3, 2025, which describes an aerosol generating device. In this patent, the elastic force generated by an elastic element keeps the upper shell pressed firmly against the lower shell. This improves the sealing performance between the upper and lower shells when the upper shell is frequently opened and closed. The use of concave and convex points for positioning enhances the tactile feel during positioning, and the use of magnets increases the damping during opening and closing, improving positioning accuracy and sealing. However, this patent lacks a refined design for the heating and atomizing mechanism, such as a hollow annular heating sleeve and a spiral heating wire for uniform heating. It also lacks a multi-stage filtration system for dual filtration of the aerosol, and the smoke delivery component does not employ a quick-release structure with elastic locking. Utility Model Content

[0004] The purpose of this utility model is to provide a heated non-combustible aerosol generating device to solve the problems of the existing heated non-combustible aerosol generating device mentioned in the background art. However, the existing heated non-combustible aerosol generating device may have problems such as uneven heating of the smoke agent during speed adjustment and heating aerosol generation, inconvenient disassembly of components during maintenance, lack of multi-stage design for aerosol filtration, and non-ergonomic mouthpiece during the speed adjustment and heating aerosol generation process.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heated non-combustible aerosol generating device, comprising a smoke bottle, wherein a suction mounting mechanism is provided on one side surface of the smoke bottle, and a heating atomization mechanism is provided on one side surface of the suction mounting mechanism;

[0006] The suction installation mechanism includes a siphon tube, which is movably installed on the inner wall surface of the e-liquid bottle.

A release ring that matches the locking male component is slidably connected to the outer surface of the locking rod. A locking female component is attached to one side surface of the locking male component. A limiting spring is fixedly connected to one side surface of the locking female component.

[0007] Preferably, the heating atomizing mechanism includes an atomizing sleeve, which is threadedly connected to one side surface of the cigarette bottle. An electric heating sleeve is provided on the inner wall surface of the atomizing sleeve. A suction tube groove adapted to a locking male component is fixedly connected to one side surface of the electric heating sleeve. An atomizing filter is provided on the side surface of the suction tube groove away from the locking male component. A front cover adapted to the suction tube groove is fixedly connected to one side surface of the atomizing sleeve. A mouthpiece is threadedly connected to one side surface of the front cover. A filter medium adapted to the front cover is movably installed on the inner wall surface of the mouthpiece. A power switch assembly is provided on the outer surface of the atomizing sleeve.

[0008] Preferably, a mounting groove is provided on one side surface of the heating sleeve, and the locking female part is fixedly connected to the inner wall surface of the mounting groove by a limiting spring.

[0012] Preferably, one side of the mouthpiece has a duckbill-shaped cross-section and is fitted to the front cover through a filter medium.

[0013] Compared with the prior art, the beneficial effects of this utility model are: this heating non-combustible aerosol generating device,

[0014] 1. By setting up the suction installation mechanism, the flexible snap-fit ​​structure enables the rapid docking and separation of the smoke transfer component and the heating component, which solves the problems of cumbersome threaded connections or easily damaged snaps in traditional devices. At the same time, the limit ring design ensures connection accuracy and avoids the risk of leakage, significantly improving ease of use and structural stability.

[0015] 2. Through the design of the heating and atomizing mechanism, the hollow ring-shaped heating sleeve and the spiral heating wire form a surrounding heating space, making the e-liquid heat more evenly.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a heated non-combustible aerosol generating device, including a smoke bottle 1, a suction installation mechanism 2 is provided on one side surface of the smoke bottle 1, and a heating atomization mechanism 3 is provided on one side surface of the suction installation mechanism 2.

[0025] The suction installation mechanism 2 includes a siphon tube 201, which is movably installed on the inner wall surface of the e-liquid bottle 1. A locking rod 202 is fixedly connected to one side of the siphon tube 201. A limiting ring 203 is fixedly connected to the side of the locking rod 202 away from the siphon tube 201. A locking male component 204 is fixedly connected to the side of the locking rod 202 away from the limiting ring 203. A release ring 205, which is compatible with the locking male component 204, is slidably connected to the outer surface of the locking rod 202. A locking female component 206 is attached to one side of the locking male component 204. A limiting spring 207 is fixedly connected to one side of the locking female component 206. With the suction installation mechanism 2 in place, during use, the siphon tube 201 is inserted into the e-liquid bottle 1, and the locking rod 202 is elastically engaged with the locking female part 206 through the locking male part 204. The limiting ring 203 restricts the insertion depth, and the release ring 205 can slide to squeeze the locking female part 206 to compress the limiting spring 207 to release the lock. During suction, the negative pressure causes the e-liquid to enter the heating and atomizing mechanism 3 through the siphon tube 201. The siphon tube 201 and the heating and atomizing mechanism 3 are elastically locked through the locking male part 204 and the locking female part 206. The limiting ring 203 ensures accurate docking, and the release ring 205 enables quick disassembly, facilitating the stable connection and maintenance of the e-liquid transmission path.

[0026] Furthermore, the heating and atomizing mechanism 3 includes an atomizing housing 301, which is threadedly connected to one side surface of the e-liquid bottle 1. An electric heating sleeve 302 is provided on the inner wall surface of the atomizing housing 301. A suction tube groove 303 adapted to the engaging male component 204 is fixedly connected to one side surface of the electric heating sleeve 302. An atomizing filter 304 is provided on the side surface of the suction tube groove 303 away from the engaging male component 204. A front cover 305 adapted to the suction tube groove 303 is fixedly connected to one side surface of the atomizing housing 301. A mouthpiece 306 is threadedly connected to one side surface of the front cover 305. A filter medium 307 adapted to the front cover 305 is movably installed on the inner wall surface of the mouthpiece 306. A power switch assembly 308 is provided on the outer surface of the atomizing housing 301. With the heating atomizing mechanism 3 in place, the atomizing housing 301 is threadedly connected to the e-liquid bottle 1. After the heating sleeve 302 is powered on, the spiral heating wire heats the e-liquid. The e-liquid enters the heating area through the suction tube groove 303 and vaporizes. The atomized mist is dispersed and filtered by the atomizing filter 304. The front cover 305 is connected to the mouthpiece 306. The filter medium 307 filters the atomized mist a second time. The power switch assembly 308 controls the on / off state. The spiral heating wire of the heating sleeve 302 heats the e-liquid evenly. The atomizing filter 304 refines the atomized mist and filters impurities. The duckbill-shaped design of the mouthpiece 306, combined with the filter medium 307, optimizes the vaping experience. The modular structure facilitates replacement and cleaning.

[0027] Furthermore, an installation groove is provided on one side surface of the heating sleeve 302. The locking female part 206 is fixedly connected to the inner wall surface of the installation groove by the limiting spring 207. With the setting of the heating sleeve 302, when the locking male part 204 is inserted into the installation groove, the limiting spring 207 provides elastic support force, so that the locking female part 206 automatically pops out and locks the locking male part 204, realizing a quick and stable connection between the siphon tube 201 and the heating sleeve 302. At the same time, when disassembling, the compression spring can release the locking, improving the convenience of device assembly and maintenance.

[0028] Furthermore, the heating mantle 302 has a hollow ring-shaped cross-section, and heating wires are provided on the inner wall surface of the heating mantle 302. The heating wires are spiral-shaped along the inner wall surface of the heating mantle 302. Through the design of the cross-section of the heating mantle 302, the hollow ring structure forms a surrounding heating space during use, and the spiral heating wires are evenly distributed on the inner wall, so that the liquid smoke agent flowing through the suction tube groove 303 can come into contact with the heat source in all directions, thereby achieving efficient and uniform heating of the smoke agent, improving atomization efficiency and ensuring the stability of the aerosol composition.

[0029] Furthermore, the locking female part 206 and the limiting spring 207 are symmetrically arranged in three sets around the central axis of the locking male part 204. The locking rod 202 is attached to the outer surface of the heating sleeve 302 through the locking female part 206 and the limiting spring 207. Through the design of the locking female part 206 and the limiting spring 207, the three sets of symmetrical elastic locking structures can evenly distribute the locking stress during use, ensuring that the siphon tube 201 and the heating sleeve 302 are connected with balanced force and stable and reliable, avoiding the skewing or loosening that may be caused by single-point locking. At the same time, the symmetrical layout facilitates quick alignment and installation, improving assembly efficiency.

[0030] Furthermore, one side surface of the atomizing filter 304 and the front cover 305 is porous, and their central axes coincide. Through the design of the atomizing filter 304 and the front cover 305, the porous structure allows the atomized mist to pass through evenly and further refine the particles during use. The coincidence of the central axes ensures that the mist transmission path is smooth and unobstructed, effectively improving the mist filtration efficiency and conduction stability. At the same time, it facilitates the alignment and installation of components, ensuring the consistency and reliability of the airflow inside the device.

[0031] Furthermore, one side of the mouthpiece 306 has a duckbill-shaped cross-section and is fitted to the front cover 305 through the filter medium 307. Through the design of the mouthpiece 306, the duckbill-shaped cross-section conforms to ergonomics during use, making it easy to fit the lips and enjoy comfortable inhalation. The tight fit between the filter medium 307 and the front cover 305 ensures that the aerosol completely passes through the filter layer, effectively adsorbing impurities and odors. At the same time, the duckbill structure guides the aerosol smoothly into the mouth, reducing irritation and improving the comfort and purity of the inhalation experience.

[0032] Working principle: When the device is started, the internal power supply provides power to the system. When the user turns on the power switch assembly 308, the spiral heating wires on the inner wall of the heating mantle 302 are energized and heat up, evenly heating the hollow annular inner cavity of the heating mantle 302. At this time, the end of the siphon tube 201 extends into the bottom of the e-liquid bottle 1. Through the negative pressure effect generated by the user's suction action, the liquid e-liquid in the e-liquid bottle 1 is drawn into the transmission channel through the inner cavity of the siphon tube 201. The e-liquid rises along the siphon tube 201 to the port of the engaging connector 204, and enters the heating area of ​​the heating mantle 302 through the precisely aligned suction tube groove 303. Inside the heating mantle 302, the spirally distributed heating wires are connected to the heating mantle 302. The liquid e-liquid in the suction tube 303 undergoes a surrounding heating process, causing the effective components in the e-liquid to gradually vaporize into a preliminary aerosol at a suitable temperature. This preliminary aerosol continues to move forward, and as it passes through the porous structure of the atomizing filter 304, larger droplets are broken into micron-sized particles. Simultaneously, it intercepts incompletely vaporized residual droplets and solid impurities, improving the fineness and purity of the aerosol. The atomized aerosol then enters the mouthpiece 306 through the porous channels of the front cover 305. The built-in activated carbon cotton, flavor capsule filter, and other porous materials further treat the aerosol. The microporous structure adsorbs condensate and small particles, while the activated carbon material degrades volatile organic compounds and neutralizes odors. The duckbill-shaped cross-section of the mouthpiece 306 conforms to the curve of the lips, guiding the aerosol smoothly into the mouth along a preset path, reducing direct irritation to the throat. When the user inhales, the airflow carries the aerosol through the filter medium 307, forming a gentle inhalation experience through the outlet of the mouthpiece 306. When the power switch assembly 308 is turned off, the heating wire stops working, and the temperature of the heating jacket 302 gradually drops. The device adopts a modular and detachable design. The atomizing shell 301 is separated from the e-liquid bottle 1 by threads. The siphon tube 201 is quickly disengaged by the elastic snap-fit ​​structure of the male and female parts 206. Three sets of symmetrically distributed limit springs 207 provide locking force. This design facilitates user disassembly and cleaning of components prone to residue buildup, such as the siphon tube 201 and atomizing filter 304, preventing the smoke agent from solidifying and clogging the channels. Throughout the entire process, the negative pressure of suction drives the smoke agent circulation, and the precise temperature control mechanism of the heating mantle 302 avoids the risk of producing harmful substances such as tar in traditional combustion methods. Combined with a multi-stage filtration structure, it achieves the design goals of low-temperature atomization, efficient delivery, and a harm-reduced experience. Users can replace different types of filter media 307, such as those containing specific flavored capsules or highly absorbent activated carbon, to flexibly adjust the aerosol flavor, balancing personalization and practicality. This completes the usage process of a heated non-combustible aerosol generator.
