Description

Technical Field

[0001] This utility model relates to the field of atomizing device technology, specifically to an aerosol bullet and atomizing device. Background Technology

[0002] Atomizing devices are commonly used in e-cigarettes and drug atomization. Current atomizing devices convert liquid e-liquid or medication into aerosols for users to inhale. Ideally, the aerosol particle size should be concentrated between 1-3 μm to achieve efficient lung deposition and reduce oropharyngeal irritation. However, existing atomizers generally suffer from an excessively high proportion of large particles (>5 μm), leading to the following drawbacks: 1. Dry and irritated throat: Large particles deposit in the oropharynx, damaging the mucosal barrier and triggering an inflammatory response, resulting in persistent dryness and a burning sensation. 2. Degraded taste: Large particles carrying insufficiently atomized e-liquid (containing high-viscosity glycerol) directly contact the back of the tongue, producing a "burnt" taste and reducing the vaping experience. 3. Health risks: Long-term use may lead to oropharyngeal inflammation developing into chronic pharyngitis, and the incompletely decomposed formaldehyde (from the thermal decomposition of propylene glycol) in large particles increases the risk of respiratory damage.

[0003] In view of the above, this application is hereby submitted. Summary of the Invention

[0004] This utility model provides an aerosol bullet and atomizing device to solve at least one of the above-mentioned technical problems.

[0005] An aerosol cartridge includes an atomizing core and a liquid storage element, and also includes a nozzle.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0030] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0031] Please refer to Figures 1 to 3 An aerosol bullet 100 includes an atomizing core 1, a liquid storage element 2, and a mouthpiece 3. The atomizing core 1 is located inside the liquid storage element 2, and the mouthpiece 3 is disposed on the top of the liquid storage element 2. An airflow channel 24 is provided between the mouthpiece 3 and the atomizing core 1, so that after the atomizing core 1 heats and atomizes the atomized liquid in the liquid storage element 2, it can flow quickly to the mouthpiece 3 through the airflow channel 24.

[0032] The nozzle 3 is provided with at least one airflow hole 31 that communicates with the airflow channel 24 via the aerosol, and the wall of the airflow hole 31 of the nozzle 3 is made of fibrous material or porous material. By providing the airflow hole 31 on the nozzle 3, the aerosol can pass through the nozzle 3 more smoothly without affecting the suction efficiency. Furthermore, by making the wall of the airflow hole 31 a fibrous material or porous material that can absorb large particles in the aerosol, the large particles in the aerosol passing through the airflow hole 31 are absorbed, thereby reducing the proportion of large particles in the aerosol cartridge 100 during use. This prevents large particles from depositing in the oropharynx, damaging the mucosal barrier, causing dryness and irritation in the throat, and reducing health risks. It also prevents large particles from directly contacting the back of the tongue, improving the suction experience.

[0033] Please refer to Figure 1 In this embodiment, the airflow hole 31 is arranged along the direction of the airflow channel 24, that is, it is arranged in a straight line along the direction of the airflow channel 24. This arrangement can not only improve the efficiency of aerosol delivery, but also make the manufacturing simple and low in cost.

[0034] Preferably, the diameter of the airflow hole 31 is 0.5~5mm, the length of the airflow hole 31 is 5~20mm, and the number of airflow holes 31 is 1~5. The longer the airflow hole 31 is, the better. Therefore, the length range of the airflow hole 31 is preferably 0.7~1 times that of the mouthpiece 3. The better the absorption effect, the more the better under the same flow cross section conditions. Within this range, the ratio of large particles can be reduced and the taste can be optimized.

[0035] In a further preferred embodiment, the airflow hole 31 has a diameter of 1 mm, a length of 12 mm, and a quantity of 3 airflow holes 31.

[0036] In this embodiment, there is one airflow hole 31, and the diameter of the airflow hole 31 is approximately the same as the diameter of the airflow channel 24.

[0037] In other embodiments, the airflow hole 31 can also be bent, which is beneficial to improving the efficiency of absorbing large particles of mist.

[0038] In this embodiment, the airflow hole 31 on the nozzle 3 is an axially penetrating airflow hole. Thus, in a preferred embodiment, the nozzle 3 is cut from a nozzle blank of N times its length in a single molding process, where N is a positive number greater than 3. This is because the airflow hole 31 is axially penetrating, so when manufacturing a nozzle blank of N times its length, a simple mold can be used for molding, and only the length of one nozzle 3 needs to be cut, which greatly reduces the production cost.

[0039] Furthermore, the airflow hole 31 is an airflow hole that directly communicates with the airflow channel 24, improving the airflow efficiency of the aerosol bullet 100. Since the aerosol in the airflow channel 24 and the airflow hole is in gaseous form, large particles are absorbed efficiently when they flow through the hole wall of the airflow hole 31. Experiments have verified that when the hole wall material of the airflow hole 31 is cotton fiber, the diameter of the airflow hole 31 ranges from 0.8 to 3 mm, the length ranges from 8 to 15 mm, and the number is 1 to 3, the absorption efficiency of large particles is even higher.

[0040] The porous structural material used as the wall of the airflow pore 31 can be a porous ceramic that forms a microporous structure through high-temperature sintering and can intercept particulate matter in aerosols, such as polylactic acid (PLA) which has hydrophobic and oil-absorbing properties.

[0041] Porous materials also include porous silica gel. Ordinary silica gel typically has pores ranging from micrometers to nanometers in size, allowing it to adsorb particles through van der Waals forces and electrostatic interactions. Because silica gel pores are smaller than the large particles in smoke, this facilitates the absorption of larger particles, resulting in high adsorption efficiency. Conversely, if the silica gel pores are too large, large particles may penetrate, leading to poor adsorption. Furthermore, silica gel is relatively soft and elastic, improving its feel and enhancing the user experience.

[0042] Porous materials can also be other porous materials that can adsorb large particles in smoke and mist, such as PEEK foam and silicone rubber composites.

[0043] In a preferred embodiment, the wall of the airflow hole 31 is made of fibrous material, which may be cellulose, polypropylene fiber, polyethylene terephthalate fiber or polyamide fiber.

[0044] Preferably, the fiber material is a plastic fiber material, which is convenient to manufacture and to form the airflow holes 31; the material is relatively light and the cost is low.

[0045] Cellulose is a polysaccharide composed of glucose molecules linked by β-1,4-glycosidic bonds, and is widely found in plant cell walls. It includes natural fibers such as cotton, kapok, flax, ramie, jute, bamboo, sisal, abaca, and coconut fiber.

[0046] This also includes fibers made by chemically dissolving plant cellulose and then re-spinning them; regenerated cellulose fibers that combine the characteristics of natural cellulose with the advantages of synthetic fiber processes; including viscose fibers made by wet spinning viscose lysizing viscose lysizing viscose lysizing viscose lysizing viscose lysizing viscose lysizing viscose lysizing viscose lysizing viscose lysing ...

[0047] Preferably, the walls of the airflow hole 31 and the nozzle 3 are entirely made of plastic fiber.

[0048] Please refer to Figure 4 In a preferred embodiment, a filter screen 32 is provided between the airflow hole 31 and the airflow channel 24, or a filter screen 32 is provided inside the airflow hole 31. This allows for better filtration of large particles in the aerosol. The filter screen 32 is made of plastic fiber or cellulose, and its thickness is 0.3~1mm, thus effectively balancing the efficiency of aerosol flow during suction with the effect of filtering large particles in the aerosol.

[0049] In other embodiments, the airflow hole 31 of the suction nozzle 3 can be a blind hole, with one end sealed by plastic fiber. The part that seals the airflow hole 31 functions as the filter screen 32, thus eliminating the need for a separate filter screen 32.

[0050] In this embodiment, the liquid storage element 2 includes a liquid storage cavity 21, which has a hollow structure for forming an airflow channel 24, and a filling material 23 for absorbing atomized liquid inside the liquid storage cavity 21. The filling material 23 is cotton fiber, non-woven fabric, sponge, wood fiber, polypropylene fiber, polyethylene terephthalate fiber, polyamide fiber, polylactic acid or polyurethane foam.

[0051] Unlike traditional liquid storage chambers 21, which are simply empty cavities for holding atomized liquid, the liquid storage chamber 21 in this embodiment is provided with a filling material 23 for absorbing atomized liquid. Thus, even after the atomized liquid in the liquid storage chamber 21 is continuously atomized and used by the atomizing core 1, the filling material 23 still exists in the liquid storage chamber 21. This filling material 23 can insulate the airflow channel 24 with a hollow structure in the middle, preventing the airflow channel 24 from becoming hollow after the atomized liquid in the liquid storage chamber 21 is used, which would result in poor insulation and affect the vaping experience.

[0052] Please refer to Figure 1 The liquid storage element 2 further includes a sealing plug 22, which is disposed between the liquid storage cavity 21 and the suction nozzle 3 to seal the liquid storage cavity 21.

[0053] Please refer to Figure 2 and Figure 3The atomizing core 1 includes a heating element 11 and a liquid guiding element 12. The heating element 11 is wound around the outer wall of the liquid guiding element 12, and the liquid guiding element 12 is arranged along the radial direction of the liquid storage cavity 21. The heating element 11 includes a heating section 111 and a conductive section 112, and the conductive section 112 is wound around the outer wall of the liquid guiding element 12 at least 1 / 4 turn. The heating section 111 of the heating element 11 is a metal resistance wire, and the gap 'a' between two adjacent turns of the heating section 111 is less than 0.5 mm.

[0054] Preferably, the gap 'a' between two adjacent rings of heating section 111 is 0.2~0.35mm, and the heating effect is better within this gap value.

[0055] The liquid guiding element 12 of the atomizing core 1 is preferably made of cellulose material or cotton fiber. The cotton fiber allows liquid e-liquid to quickly penetrate to the front end of the guiding element. This reduces the time difference in liquid guiding, preventing the lower layer of e-liquid in the reservoir 21 from failing to replenish in time, reducing the risk of dry burning. Furthermore, natural cotton fiber eliminates the risk of heavy metal leaching, avoiding the release of harmful substances such as lead and cadmium that may be present in the ceramic core. It possesses the advantages of natural cotton fiber eliminating the risk of heavy metal leaching and avoiding the release of harmful substances such as lead and cadmium that may be present in the ceramic core.

[0056] The aerosol cartridge 100 also includes a tube body 6, which covers the outside of the liquid storage element 2. The tube body 6 is mainly made of cellulose, preferably paper, and can also wrap around the outside of the nozzle 3 to improve the user experience.

[0057] Please refer to Figure 1 The aerosol canister 100 also includes a base 4, which is located at the bottom of the liquid storage element 2 and is equipped with a contact electrode 41, which is electrically connected to the heating element 11. The base 4 is provided with an atomizing air channel 42, the core function of which is to efficiently transport aerosols, balance system pressure, control temperature, and ensure safety.

[0058] Please refer to Figure 5 The present invention also provides an atomizing device, including a battery rod 5 and an aerosol bullet 100 as described above, wherein the battery rod 5 is used to supply power to the atomizing core 1 of the aerosol bullet 100.

[0059] The battery rod 5 includes a housing 51, a battery 52, an electrode spring 55, a control board 53, and a charging port 54. The battery 52 is located inside the housing 51, and the charging port 54 is used to charge the battery 52. ​​The electrode spring 55 is electrically connected to the battery 52 through the control board 53, so the control board 53 can control the amount of current delivered by the electrode spring 55 to the contact electrode 41 on the base 4, and further, it can also control the amount of voltage, thereby controlling the working status of the atomizing core 1.

[0060] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
