Description

Technical Field

[0001] The present invention relates to the technical field of atomizing devices, and in particular to an aerosol bomb and an atomizing device. Background Art

[0002] Atomizers are often used in fields such as e-cigarettes and drug atomization. Current atomizers convert liquid e-liquid or drugs into aerosols for users to inhale through atomizers. The ideal aerosol particle size should be concentrated in 1-3μm to achieve efficient lung deposition and reduce oropharyngeal irritation. However, existing atomizers generally have the problem of too high a proportion of large particles (>5μm), resulting in the following defects: 1. Dry throat and irritation: Large particles are deposited in the oropharynx, destroying the mucosal barrier, triggering an inflammatory response, and users experience persistent dryness and burning sensations. 2. Deterioration of taste: The inadequately atomized e-liquid (containing high-viscosity propylene glycol) carried by large particles directly contacts the root of the tongue, producing a "burnt core" odor and reducing the smoking experience. 3. Health risks: With long-term use, oropharyngeal inflammation may develop into chronic pharyngitis, and the incompletely decomposed formaldehyde (from thermal decomposition of propylene glycol) in large particles increases the risk of respiratory damage.

[0028] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0029] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention. In the description of the present invention, unless otherwise specified, the meaning of "plural" is two or more.

[0030] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings.

[0031] Please refer to Figures 1 to 3, an aerosol bomb 100, comprising an atomization core 1, a liquid storage element 2, and a mouthpiece 3. The atomization core 1 is located inside the liquid storage element 2, the mouthpiece 3 is arranged at the top of the liquid storage element 2, and there is an air flow channel 24 between the mouthpiece 3 and the atomization core 1. After the atomization core 1 heats and atomizes the atomized liquid in the liquid storage element 2, it can quickly flow to the mouthpiece 3 through the air flow channel 24.

[0032] The mouthpiece 3 is provided with at least one air flow hole 31 that is in aerosol communication with the air flow channel 24, and the pore wall of the air flow hole 31 of the mouthpiece 3 comprises a fiber material or a porous structure material. By providing the air flow hole 31 on the mouthpiece 3, the aerosol can pass through the mouthpiece 3 more smoothly, without affecting the suction efficiency. And by setting the pore wall of the air flow hole 31 as a fiber material or a porous structure material that can absorb large aerosol particles, the large particles in the aerosol passing through the air flow hole 31 are absorbed, thereby reducing the proportion of large particles in the aerosol bomb 100 during use, avoiding the deposition of large particles in the oropharynx, damaging the mucosal barrier, causing throat dryness and irritation, and reducing health risks; avoiding the direct contact of large particles with the root of the tongue and improving the suction taste.

[0033] Please refer to Figure 1 , in this embodiment, the air flow hole 31 is arranged along the direction of the air flow channel 24, that is, arranged in a straight line along the direction of the air flow channel 24. This setting method can not only improve the efficiency of aerosol transportation but also is simple to manufacture and has a low manufacturing cost.

[0034] Preferably, the diameter of the air flow hole 31 is 0.5 - 5 mm, the length of the air flow hole 31 is 5 - 20 mm, and the number of the air flow holes 31 is 1 - 5. The longer the length of the air flow hole 31, the better the absorption effect. Under the condition of the same flow cross-section, the more the number, the better. Within this range, the ratio of large particles can be reduced and the taste can be optimized.

[0035] In a further preferred embodiment, the diameter of the air flow hole 31 is 1 mm, the length of the air flow hole 31 is 12 mm, and the number of the air flow holes 31 is 3.

[0036] In this embodiment, the number of the air flow holes 31 is 1, and the diameter of the air flow hole 31 is substantially the same as the diameter of the air flow channel 24.

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

[0038] In this embodiment, the air flow holes 31 on the nozzle 3 are axially penetrating air flow through holes. Thus, in a preferred embodiment, the nozzle 3 is cut from a nozzle blank with a length N times that of a single molding, where N is a positive number greater than 3. This is because the air flow holes 31 penetrate axially, so when manufacturing a nozzle blank with a length N times that of a single molding, a simple mold can be used for molding, and then only the length of one nozzle 3 needs to be cut, greatly reducing the production and manufacturing costs.

[0039] Furthermore, the air flow holes 31 are air flow through holes that directly communicate with the air flow channel 24, improving the air flow efficiency of the aerosol bomb 100. And since the aerosol in the air flow channel 24 and the air flow through holes is in a gaseous state, when large particles flow through the pore walls of the air flow holes 31, the absorption efficiency is high. After experimental verification, when the material of the pore walls of the air flow holes 31 is cotton fiber, the diameter range of the air flow holes 31 is 0.8 - 3 mm, the length range is 8 - 15, and the number is 1 - 3, the absorption efficiency of large particles is even higher.

[0040] The porous structure material serving as the pore walls of the air flow holes 31 can be a porous ceramic formed by high-temperature sintering to form a microporous structure and capable of intercepting particulate matter in the aerosol, a polylactic acid (PLA) with hydrophobicity and oil absorption, etc.

[0041] The porous structure material also includes porous silica gel. The pores of ordinary silica gel are usually in the range of micrometers to nanometers, and particles can be adsorbed through van der Waals forces and electrostatic interactions. Since the pores of the silica gel are smaller than the large particles in the smoke, this is conducive to the absorption of large particles, and the adsorption efficiency is relatively high; if the pores of the silica gel are too large, it may instead cause large particles to penetrate, resulting in a poor adsorption effect. Moreover, the silica gel material is relatively soft and elastic, improving the hand feeling and enhancing the usage experience.

[0042] The porous structure material can also be other porous structure materials capable of adsorbing large particles in smoke and aerosol, such as PEEK foam, silicone rubber composites, etc.

[0043] In a preferred embodiment, the pore walls of the air flow holes 31 are made of fiber materials, and the fiber materials can be cellulose, polypropylene fiber, polypropylene fiber, polyethylene terephthalate fiber, or polyamide fiber.

[0044] Among them, preferably, the fiber material is a plastic fiber material, which is convenient for manufacturing and the formation of the air flow holes 31; the material is light in weight and low in cost.

[0045] Cellulose is a polysaccharide formed by connecting glucose molecules through β-1,4-glycosidic bonds and is widely present in plant cell walls. It includes cotton fiber, kapok fiber, flax, ramie, jute, bamboo fiber, sisal, abaca, and coconut fiber in natural fibers.

[0046] It also includes fibers made by redissolving plant cellulose through chemical means and then re-spinning, which are regenerated cellulose fibers that combine the characteristics of natural cellulose and the advantages of synthetic fiber processes. These include viscose fibers made by alkalizing, aging, and xanthating wood or cotton linters and then wet-spinning the viscose solution, modal fibers made from beech wood pulp using the solvent spinning method, and acetate fibers obtained by reacting cellulose with acetic anhydride, etc.

[0047] Preferably, the pore walls of the air holes 31 and the entire nozzle 3 are made of plastic fibers.

[0048] Please refer to Figure 4 , in a preferred embodiment, a filter screen 32 is provided between the air holes 31 and the air flow channel 24, or a filter screen 32 is provided inside the air holes 31. This can better filter large particles in the aerosol. The filter screen 32 is made of plastic fibers or cellulose, and the thickness of the filter screen 32 is 0.3 - 1 mm, so as to better balance the efficiency of aerosol flow during suction and the effect of filtering large particles in the aerosol.

[0049] In other embodiments, the air holes 31 of the nozzle 3 can also be blind holes, with one end blocked by plastic fibers. The part blocking the air holes 31 serves the function of the filter screen 32, thus eliminating the need to separately place an independent filter screen 32.

[0050] In this embodiment, the liquid storage element 2 includes a liquid storage cavity 21, the liquid storage cavity 21 is provided with a hollow structure for forming the air flow channel 24, and the liquid storage cavity 21 is filled with a filling material 23 for absorbing the atomized liquid. 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] Different from the traditional liquid storage cavity 21 which is only a cavity for containing the atomized liquid, the liquid storage cavity 21 in this embodiment is provided with a filling material 23 for absorbing the atomized liquid. Thus, when the atomized liquid in the liquid storage cavity 21 is continuously atomized and used by the atomizing core 1, the filling material 23 still exists in the liquid storage cavity 21. This filling material 23 can play the role of insulating the air flow channel 24 of the central hollow structure, avoiding the poor heat preservation effect due to the hollow structure of the tube wall corresponding to the air flow channel 24 after the atomized liquid in the liquid storage cavity 21 is used, which affects the suction taste.

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

[0053] Please refer to Figure 2 and Figure 3, the atomization 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. 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. The conductive section 112 is wound around the outer wall of the liquid guiding element 12 for at least 1 / 4 turn. The heating section 111 of the heating element 11 is a resistance wire made of metal material, and the gap a between adjacent turns of the heating section 111 of the heating element 11 is less than 0.5 mm.

[0054] Preferably, the gap a between adjacent turns of the heating section 111 is 0.2 - 0.35 mm, and the heating effect is better within this gap value range.

[0055] Among them, the liquid guiding element 12 of the atomization core 1 includes a cellulose material, preferably cotton fiber. The cotton fiber can enable the liquid e - liquid to quickly penetrate to the front end of the liquid guiding, reduce the liquid guiding time difference, avoid the inability to timely supplement the e - liquid at the lower layer of the liquid storage cavity 21, reduce the risk of dry burning, and there is no risk of heavy metal precipitation in natural cotton fiber, avoiding the release of harmful substances such as lead and cadmium that may exist in the ceramic core. It has the advantages of no risk of heavy metal precipitation in natural cotton fiber and avoiding the release of harmful substances such as lead and cadmium that may exist in the ceramic core.

[0056] The aerosol cartridge 100 further includes a tube body 6. The tube body 6 covers the outside of the liquid storage element 2. The material of the tube body 6 is mainly cellulose, preferably paper. Further, it can also wrap the outside of the mouthpiece 3, thereby improving the use experience.

[0057] Please refer to Figure 1 , the aerosol cartridge 100 further includes a base 4. The base 4 is located at the bottom of the liquid storage element 2, and a contact electrode 41 is provided. The contact electrode 41 is electrically connected to the heating element 11. The base 4 is provided with an atomization air passage 42. The core function of the atomization air passage 42 on the base 4 is to efficiently transmit the aerosol, balance the system pressure, control the temperature and ensure safety.

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

[0059] The battery rod 5 includes a housing 51, a battery 52, an electrode pin 55, a control board 53 and a charging port 54. The battery 52 is located inside the housing 51. The charging port 54 is used to charge the battery 52. The electrode pin 55 is electrically connected to the battery 52 through the control board 53. Thus, the control board 53 can control the magnitude of the current transmitted by the electrode pin 55 to the contact electrode 41 on the base 4. Further, it can also control the magnitude of the voltage, thereby controlling the working condition of the atomization core 1.

[0060] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention.
