Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to an electronic cigarette atomization and heating device. Background Technology

[0002] Electronic cigarettes, also known as e-cigarettes, are widely used as a substitute for regular cigarettes because they do not involve combustion and therefore do not produce toxic substances such as tar, carbon monoxide, and nitrous acid. The atomizer coil is the core component of an electronic cigarette; its basic working principle is to heat and atomize e-liquid with a cigarette flavor into a vapor form for the smoker to use.

[0003] In related technologies, to increase e-liquid capacity, large-capacity disposable e-cigarettes typically use e-liquid storage cotton. However, using e-liquid storage cotton results in some e-liquid residue remaining on the cotton, reducing the proportion of effectively atomized e-liquid and leading to a burnt taste when vaping. Furthermore, under high-power atomization demands, the e-liquid supply is slow, failing to meet product requirements. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model aims to provide an electronic cigarette atomizing and heating device that can meet the requirements of high-power atomization without producing a burnt smell.

[0005] The technical solution of this utility model is implemented as follows:

[0006] An electronic cigarette atomizing and heating device includes an atomizing core assembly, oil-absorbing cotton, an outer tube, and a sealing ring;

[0007] The atomizing core assembly includes a positioning rod, a heating mesh tightly attached to the outside of the positioning rod, and composite cotton and an inner tube sequentially and axially installed on the outside of the heating mesh.

[0008] The oil-absorbing cotton is axially sleeved on the outside of the atomizing core assembly, the outer tube is axially sleeved on the outside of the oil-absorbing cotton, the sealing ring is axially embedded between the inner tube and the outer tube and seals the end of the oil-absorbing cotton, and the end of the outer tube away from the sealing ring extends axially and its length is greater than the length of the oil-absorbing cotton, wrapping the oil-absorbing cotton inside the outer tube so that an oil storage chamber is formed between the outer tube and the inner tube.

[0009] Preferably, the outer tube is a hollow columnar structure, and the outer tube has multiple oil suction holes penetrating its inner and outer opposite surfaces.

[0010] Preferably, the plurality of oil suction holes are arranged at circumferential intervals.

[0011] Preferably, the outer tube is a stainless steel outer tube.

[0012] Preferably, the inner tube is a hollow columnar structure, and the inner tube has multiple oil guide holes that penetrate its inner and outer opposite surfaces.

[0016] Preferably, the sealing ring is a rubber sealing ring.

[0017] Preferably, it also includes a stop plug, the stop plug being embedded in the inner hole of the stop plug.

[0018] The electronic cigarette atomizing and heating device provided in this embodiment of the utility model sets the length of the outer tube to be much greater than the length of the oil-absorbing cotton, and installs the sealing ring at the ends of the oil-absorbing cotton and the outer tube, so that the space between the inner tube and the outer tube of the atomizing core assembly is completely sealed. In this way, an oil storage space is formed between the oil-absorbing cotton and the outer tube, which greatly increases the oil storage capacity.

[0022] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the technical solutions in 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 some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Please refer to the following: Figures 1 to 3This utility model provides an electronic cigarette atomizing and heating device. The electronic cigarette atomizing and heating device includes an atomizing core assembly 1, an oil-absorbing cotton 3, an outer tube 5, and a sealing ring 7. The oil-absorbing cotton 3 and the outer tube 5 are sequentially axially sleeved on the outside of the atomizing core assembly 1. The oil-absorbing cotton 3 tightly wraps around the atomizing core assembly 1, guiding the e-liquid absorbed on it onto the atomizing core assembly 1. The atomizing core assembly 1 heats up and heats the e-liquid to produce smoke.

[0024] Specifically, the atomizing core assembly 1 includes a positioning rod 11, a heating mesh tightly attached to the outside of the positioning rod 11, and composite cotton 13 and an inner tube 15 sequentially and axially mounted on the outside of the heating mesh. A wire is connected to the heating mesh. During assembly, to prevent deformation of the heating mesh, it is first tightly attached to the positioning rod 11. The composite cotton 13 wraps around the outer periphery of the heating mesh to absorb e-liquid. The heating mesh then heats the e-liquid on the composite cotton 13 to generate vapor.

[0025] The inner tube 15 is a hollow cylindrical structure, and multiple oil guiding holes 151 are provided on the inner tube 15, penetrating its inner and outer opposing surfaces. The oil guiding holes 151 are used to guide the e-liquid on the oil-absorbing cotton 3 outside the inner tube 15 to the composite cotton 13.

[0026] Furthermore, the plurality of oil guide holes 151 are arranged circumferentially at intervals, and the plurality of oil guide holes 151 can increase the speed of oil guiding.

[0027] In this embodiment, the wicking holes 151 are arranged in multiple rings, preferably in two rings, which can further increase the wicking speed. It can be understood that the wicking holes 151 serve to guide e-liquid; therefore, in order to improve the wicking speed and allow the e-liquid to quickly enter the composite cotton 13, theoretically, the more wicking holes 151 there are, the faster the wicking speed will be, and the better it can meet the needs of high-power atomizers.

[0028] The oil-absorbing cotton 3 is axially tightly fitted outside the atomizing core assembly 1, the outer tube 5 is axially fitted outside the oil-absorbing cotton 3, the sealing ring 7 is axially embedded between the inner tube 15 and the outer tube 5 and seals the end of the oil-absorbing cotton 3, and the end of the outer tube 5 away from the sealing ring 7 extends axially and its length is greater than the length of the oil-absorbing cotton 3, wrapping the oil-absorbing cotton 3 inside the outer tube 5 so that an oil storage chamber is formed between the outer tube 5 and the inner tube 15. Therefore, the length of the outer tube 5 is much greater than the length of the oil-absorbing cotton 3. The sealing ring 7 is installed at the ends of the oil-absorbing cotton 3 and the outer tube 5, so that the space between the inner tube 15 and the outer tube 5 of the atomizing core assembly 1 is completely sealed. In this way, an oil storage space is formed between the oil-absorbing cotton 3 and the outer tube 5, which greatly increases the oil storage capacity. The oil-absorbing cotton 3 is directly immersed in oil, so that the outer tube 5 and the inner oil-absorbing cotton 3 form a built-in "oil tank". The oil intake and oil locking effect is better, which can better prevent oil leakage and clogging of the core, and is more suitable for high-power electronic cigarettes.

[0029] Specifically, in this embodiment, the outer tube 5 is a hollow columnar structure with an extra-large outer diameter, resulting in a larger oil storage capacity. This allows for better inhalation and atomization, making it suitable for various high-power atomizers and more beneficial for products with high requirements for vapor production, power, and lifespan.

[0030] Furthermore, the outer tube 5 has multiple oil suction holes 51 penetrating its inner and outer opposing surfaces. These multiple oil suction holes 51 are circumferentially spaced. Specifically, each oil suction hole 51 is a small, circular opening through which e-liquid enters the oil storage tank.

[0031] Preferably, in this embodiment, the outer tube 5 is a stainless steel outer tube 5. It is understood that the stainless steel outer tube 5 has higher strength and a longer service life.

[0032] Specifically, in this embodiment, the sealing ring 7 is a rubber sealing ring. Rubber sealing rings offer better sealing performance and have a lower chance of oil leakage.

[0033] In another embodiment, the electronic smoke atomizing heating device further includes a stop plug 9, which is embedded in the inner hole of the stop plug 9. The stop plug 9 has several wire-fixing grooves circumferentially formed, and the wires connected to the heating grid are fixed in the wire-fixing grooves. Furthermore, the stop plug 9 is made of rubber to improve the stopping effect.

[0034] The assembly process of the electronic smoke atomizing and heating device is as follows: the heating net, composite cotton 13, positioning rod 11 and inner tube 15 are assembled together to form the atomizing core component 1, which can adjust the resistance value and power and single (dual) generator according to the requirements.

[0035] Insert the built-in atomizing core assembly 1 into the sealing ring 7 from the bottom so that it is flush with the outer tube 5;

[0036] The absorbent cotton 3 is placed over the atomizer core assembly 1, and then the outer tube 5 is inserted and pressed together to make it flush with the atomizer core assembly 1. The small hole of the outer tube 5 allows it to continuously guide oil into the interior of the atomizer core assembly 1. The built-in absorbent cotton 3 will prevent excessive oil volume and provide the required amount of oil to the built-in atomizer core assembly 1.

[0037] After the atomizing heating device is assembled, it is installed inside the electronic cigarette suitable for the open-oil structure series, connected to the power supply and air passage, and e-liquid is injected into the oil cup.

[0038] The electronic cigarette atomizing and heating device provided in this embodiment of the utility model sets the length of the outer tube 5 to be much greater than the length of the oil-absorbing cotton 3, and installs the sealing ring 7 at the ends of the oil-absorbing cotton 3 and the outer tube 5, so that the space between the inner tube 15 and the outer tube 5 of the atomizing core assembly 1 is completely sealed. In this way, an oil storage space is formed between the oil-absorbing cotton 3 and the outer tube 5, which greatly increases the oil storage capacity. The oil-absorbing cotton 3 is directly immersed in oil, and an internal oil storage chamber is formed between the outer tube 5 and the inner oil-absorbing cotton 3. The oil inlet and oil locking effect is better, which can better prevent oil leakage and clogging of the core, and is more suitable for high-power electronic cigarettes.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
