Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0084] refer to Figure 1-3 The first aspect of this application provides an atomizing cartridge, which includes a liquid storage assembly 100 and an atomizing core assembly 200. The liquid storage assembly 100 includes a main body 110 and a sealing member 120. The main body 110 has a first through hole 11214, an inner chamber 130 for storing liquid, a plug hole 11215 communicating with the inner chamber 130, and a first guide hole 11216 communicating with the first through hole 11214 and the inner chamber 130. The sealing member 120 is slidably inserted into the plug hole 11215 and keeps the plug hole 11215 sealed. The atomizing core assembly 200 is detachably inserted into the first through hole 11214. The sealing member 120 is configured to be movable from an initial position to a working position, and in the initial position, it blocks the first guide hole 11216 and in the working position, it avoids the first guide hole 11216.

[0085] In the embodiments of this application, the liquid storage component 100 and the atomizing core component 200 adopt a separate and detachable structure. Therefore, they can be transported separately when not in use and reassembled when in use. At the same time, the sealing component 120 is configured to move from the initial position to the working position. In the initial position, it blocks the first guide hole 11216, and in the working position, it avoids the first guide hole 11216. Thus, the sealing component 120 can be positioned to block or avoid the first guide hole 11216. Before use, the first guide hole 11216 is blocked to reduce oil leakage. During use, the sealing component 120 avoids the first guide hole 11216 to prevent the problem of poor oil flow and easy burning.

[0086] For details, please refer to Figure 2-4In some embodiments, the sealing member 120 is provided with a clearance channel 123, which is configured such that when the sealing member 120 is in the working position, the first guide hole 11216 communicates with the inner cavity 130 through the clearance channel 123.

[0087] For more specific details, please refer to Figure 2-4 In some embodiments, the clearance channel 123 includes at least one of a through hole formed in the sealing member 120 and a notch formed in the sealing member 120. Preferably, the clearance channel 123 is a through hole formed in the sealing member 120.

[0088] Furthermore, in some implementations, reference is made to... Figure 2-7 The clearance channel 123 is configured such that, when the sealing member 120 is in its initial position, the clearance channel 123 is located outside the inner chamber 130 and accommodated within the plug hole 11215. Because the clearance channel 123 is located outside the inner chamber 130 and accommodated within the plug hole 11215, it does not come into contact with e-liquid before use, as it is not in contact with e-liquid before the sealing member 120 moves. This results in a better sealing effect and avoids oil leakage caused by incomplete sealing due to e-liquid lubrication. For example, if the clearance channel 123 is a through hole in the sealing member 120, then the through hole and its vicinity are free of oil.

[0089] Since the clearance channel 123 is located outside the inner chamber 130 and is contained in the plug hole 11215, the clearance channel 123 is not connected to the external environment. Therefore, when the sealing member 120 moves from the initial position to the working position, the clearance channel 123 does not easily bring external air into the inner chamber 130, causing pressure changes in the inner chamber 130, which can further prevent the phenomenon of e-liquid leakage.

[0090] In some implementations, reference Figure 2-7 The flow area of ​​the bypass channel 123 is larger than that of the first guide hole 11216. This larger flow area allows for a stepped e-liquid supply. After the bypass channel 123 connects to the first guide hole 11216, stepped e-liquid guidance is possible, preventing dry burning caused by gaps in the e-liquid supply. A gap refers to an area without e-liquid in the first guide hole 11216 if the diameter of the bypass channel 123 is smaller than that of the first guide hole 11216. This gap can easily lead to blocked e-liquid flow and dry burning. However, if the liquid remains connected, the traction between the liquids can create a narrow oil path.

[0091] In some implementations, reference Figure 3-9 The inner chamber 130 is an annular chamber surrounding the first through hole 11214. Multiple plug holes 11215 and multiple first guide holes 11216 are provided, with the plug holes 11215 and the first guide holes 11216 spaced apart circumferentially around the first through hole 11214. The annular structure of the inner chamber 130, surrounding the first through hole 11214, is compact. The multiple plug holes 11215 and first guide holes 11216 allow for oil guidance from multiple locations to the atomizing core assembly 200 within the first through hole 11214, resulting in more uniform oil supply and higher efficiency.

[0092] In some implementations, reference Figure 7-10 The sealing component 120 includes a reinforcing body 121 and a sealing sleeve 122. The hardness of the reinforcing body 121 is greater than that of the sealing sleeve 122. The sealing sleeve 122 is fitted onto the reinforcing body 121 and is configured to seal against the plug hole 11215. The sealing sleeve 122 is also configured to seal the first guide hole 11216 in its initial position. The reinforcing body 121 can be made of hard plastic, metal, etc., and the sealing sleeve 122 can be made of sealing rubber, silicone, etc. The reinforcing body 121 enhances the overall hardness, while the sealing sleeve 122 improves the sealing effect.

[0093] In some implementations, reference Figure 3-5 and Figure 7 The atomizing core assembly 200 includes an abutment portion 210. When the atomizing core assembly 200 is separated from the liquid storage assembly 100, the sealing member 120 is configured to remain in the initial position blocking the first guide hole 11216. When the atomizing core assembly 200 is inserted into the liquid storage assembly 100, the abutment portion 210 is configured to abut against the sealing member 120 and push the sealing member 120 to a working position that avoids the first guide hole 11216. Furthermore, by designing the abutment portion 210, when inserting the atomizing core assembly 200, the sealing member 120 can be pushed to the working position by the abutment portion 210, making it convenient and easy to operate. Specifically, the atomizing core assembly 200 may include a base bracket, an atomizing tube 220, an oil storage cotton 230, and a core body 240. The base bracket and the atomizing tube 220 can be separately formed or integrally formed. The abutment portion 210 can be an integrally formed protrusion structure protruding from the base bracket.

[0094] Regarding the structural configuration of the atomizing core assembly 200, in some embodiments, refer to... Figure 3 , Figure 6 , Figure 7 and Figure 11The atomizing core assembly 200 includes an atomizing tube 220, an oil storage cotton 230, and a core body 240. The atomizing tube 220 is detachably inserted into the first through hole 11214 and has a core cavity 221. The tube wall of the atomizing tube 220 has a second guide hole 222 communicating with the core cavity 221. The oil storage cotton 230 is inserted into the core cavity 221. The core body 240 is inserted into the core cavity 221 and communicates with the oil storage cotton 230. When the atomizing core assembly 200 is inserted into the liquid storage assembly 100, the second guide hole 222 communicates with the first guide hole 11216, thereby enabling the supply of oil to the core cavity 221 of the atomizing core assembly 200.

[0095] In some embodiments, the flow area of ​​the first guide hole 11216 is larger than the flow area of ​​the second guide hole 222. Similarly, analogous to how the flow area of ​​the bypass channel 123 is larger than the flow area of ​​the first guide hole 11216, a stepped e-liquid supply can be formed. After the bypass channel 123 connects to the first guide hole 11216, stepped e-liquid guidance can be achieved, avoiding dry burning caused by gaps in the e-liquid flow. The larger flow area of ​​the first guide hole 11216 compared to the second guide hole 222 also forms a stepped e-liquid supply, preventing dry burning caused by gaps in the e-liquid flow. With the bypass channel 123 having a larger flow area than the first guide hole 11216, and the first guide hole 11216 having a larger flow area than the second guide hole 222, a stepped, series-connected e-liquid supply can be formed, reducing the likelihood of dry burning due to blocked e-liquid pathways.

[0096] In some implementations, reference Figure 5 The atomizing tube 220 has multiple second guide holes 222 on its tube wall. In addition to supplying oil, the multiple second guide holes 222 can also facilitate air passage to balance the air pressure difference between the inner chamber 130 and the external environment, making the oil supply smoother.

[0097] In some implementations, reference Figure 3 and Figure 6 The core body 240 includes a heating element 241, and an oil-absorbing cotton 230 surrounds the heating element 241 with a height at least 1.2 times that of the heating element 241. During inhalation, the upper part of the oil-absorbing cotton 230 has a lower e-liquid content than the lower part, and the height of the oil-absorbing cotton 230 is at least 1.2 times that of the heating element 241, which can reduce overheating of the upper part of the oil-absorbing cotton 230 and reduce the phenomenon of burning dry.

[0098] Further, refer to Figure 1-9The core body 240 also includes wicking cotton, which is smaller in volume and shorter than the height of the oil storage cotton 230. The wicking cotton is sandwiched between the oil storage cotton 230 and the heating element 241. The oil storage cotton 230 stores more e-liquid than the wicking cotton, and the oil storage cotton 230 can quickly supply e-liquid to the wicking cotton, thereby allowing the e-liquid in the wicking cotton to be quickly conducted to the heating element 241. In addition, during the inhalation process, the e-liquid content in the upper part of the oil storage cotton 230 is less than that in the lower part, thus accelerating the air exchange process, for example, air can be exchanged through the second air guide hole 222.

[0099] Regarding the structural composition of the main body 110, refer to Figure 2-4 and Figure 8-10 In some embodiments, the main body 110 includes an outer shell 111 and an inner shell 112. The outer shell 111 includes a shell groove 1112 with a first opening 1111, and a second opening 1113 is formed at the top of the shell groove 1112. A first through hole 11214 is formed on the inner shell 112. The inner shell 112 is inserted into the shell groove 1112 through the first opening 1111 and blocks the first opening 1111. The first through hole 11214 communicates with the second opening 1113, and the inner shell 112 and the outer shell 111 are sealed together to define an inner chamber 130. The inner chamber 130 is used to store e-liquid. The first through hole 11214 is used to install the atomizer core assembly 200 for ventilation. The sealing between the inner shell 112 and the outer shell 111 is functionally limited; specifically, the sealing can be achieved by using a sealing ring, a sealing gasket, or by using a sealing rubber material for both the inner shell 112 and the outer shell 111 themselves.

[0100] Regarding the structural configuration of the inner housing 112. In some embodiments, refer to... Figure 2-4 and Figure 8-10 The inner shell 112 includes an inner shell body 1121 and a first sealing element 1122. The inner shell body 1121 includes a tube portion 11211 and a base portion 11212 connected to one end of the tube portion 11211. The tube portion 11211 has a mating end face facing the shell groove 1112, and a receiving portion 11213 is formed on the mating end face. The base portion 11212 covers the first opening 1111 and forms a sealing fit. The receiving portion 11213 and the shell groove 1112 are sealed by the first sealing element 1122, thereby achieving a sealing fit between the receiving portion 11213 and the shell groove 1112.

[0101] In some implementations, reference Figure 2-4 and Figure 8-10The atomizing bomb also includes a second sealing element 1123. The base portion 11212 and the first opening 1111 are sealed by the second sealing element 1123, thereby achieving a sealing fit between the base portion 11212 and the first opening 1111. Specifically, it is a sealing fit between the inner wall of the first opening 1111 and the outer peripheral wall of the base portion 11212.

[0102] In some embodiments, the outer shell 111 and the inner shell 112 are either separately formed or integrally formed. Integral forming can be produced by 3D printing.

[0103] Furthermore, specifically, in some implementations, reference is made to Figure 2-5 and Figure 7-8 The plug hole 11215 and the first guide hole 11216 are formed on the inner shell body 1121. The extension directions of the first through hole 11214 and the plug hole 11215 are parallel, and the extension direction of the first guide hole 11216 is perpendicular to the extension directions of the first through hole 11214 and the plug hole 11215. Therefore, in the embodiment where the atomizing core assembly 200 has the abutment portion 210, when the atomizing core assembly 200 is inserted into the first through hole 11214 along the axial direction of the first through hole 11214, the sealing member 120 can be pushed synchronously by the abutment portion 210, which is convenient and simple to operate.

[0104] In order to achieve pressure relief regulation of the inner chamber 130, in some embodiments, reference is made to... Figure 2-4 , Figure 7 , Figure 8 and Figure 10 The main body 110 also includes a pressure relief valve structure, which is configured to balance the pressure between the inner chamber 130 and the external environment.

[0105] Furthermore, regarding the structure of the pressure relief valve, in some embodiments, refer to... Figure 2-10 The first sealing element 1122 has a first surface facing the shell groove 1112 and a second surface facing the receiving portion 11213. A first sealing channel 300 is formed between the shell groove 1112 and the first surface, and a second sealing channel 400 is formed between the receiving portion 11213 and the second surface. The inner shell body 1121 has a pressure relief through hole 500 that connects the second sealing channel 400 and the inner cavity 130. The first sealing element 1122 also has a pressure relief diaphragm portion 600. The first sealing channel 300 and the second sealing channel 400 are connected by the pressure relief diaphragm portion 600. The first sealing channel 300 is configured to be connected to the external atmosphere, thereby forming a pressure relief valve structure.

[0106] In some implementations, reference Figure 2-10The pressure relief diaphragm section 600 includes multiple adjacent diaphragm units, which abut against each other to form pressure relief slits. The pressure relief slits are very small, and the e-liquid itself has a certain viscosity, so an oil film can be formed at the pressure relief slits. Therefore, it is difficult for oil to leak when the pressure difference is balanced. However, when the pressure difference is large, the oil film ruptures, thereby opening the first sealing channel 300 and the second sealing channel 400 to relieve pressure.

[0107] In some implementations, reference Figure 2-10 The first seal 1122 also has a punctured diaphragm portion 700, and the atomizing core assembly 200 includes a puncture tube 250. When the atomizing core assembly 200 is inserted into the liquid storage assembly 100, one end of the puncture tube 250 punctures the punctured diaphragm portion 700 and communicates with the first sealing channel 300, while the other end of the puncture tube 250 is configured to communicate with the external atmosphere. When the atomizing core assembly 200 is not inserted into the liquid storage assembly 100, if the air pressure in the inner chamber 130 is too high, the punctured diaphragm portion 700 can rupture to release pressure. When the atomizing core assembly 200 is inserted into the liquid storage assembly 100, the punctured diaphragm portion 700 is punctured and communicates with the external atmosphere through the puncture tube 250. Specifically, in some embodiments, the punctured diaphragm portion 700 is a thin film structure located between the first sealing channel 300 and the second sealing channel 400.

[0108] In some implementations, reference Figure 2-10 There are two puncture diaphragm portions 700 and two pressure relief diaphragm portions 600. The puncture diaphragm portions 700 and the pressure relief diaphragm portions 600 are arranged alternately in the circumferential direction around the first through hole 11214, which can relieve pressure from different positions and is conducive to uniform pressure relief.

[0109] In some embodiments where the puncture tube 250 is provided, the structure of the atomizing core assembly 200 is described. (See reference...) Figure 2-10 The atomizing core assembly 200 also includes an atomizing tube 220, an oil storage cotton 230, and a core body 240. The atomizing tube 220 is detachably inserted into the first through hole 11214. The atomizing tube 220 has a core cavity 221, and the tube wall of the atomizing tube 220 has a second guide hole 222 communicating with the core cavity 221. The oil storage cotton 230 is inserted into the core cavity 221. The core body 240 is inserted into the core cavity 221 and communicates with the oil storage cotton 230. The puncture tube 250 is inserted into the atomizing tube 220 and leads to the oil storage cotton 230. When the atomizing core assembly 200 is inserted into the liquid storage assembly 100, the second guide hole 222 communicates with the first guide hole 11216. The insertion of the puncture tube 250 into the atomizing tube 220 and leading to the oil storage cotton 230 can, on the one hand, relieve pressure, and on the other hand, allow the leaked oil to be absorbed by the oil storage cotton 230.

[0110] In some implementations, reference Figure 2-10The receiving part 11213 is also provided with a first through hole 800, and a connecting pipe part 900 protruding from the second surface, which penetrates the second sealing channel 400, and the connecting pipe part 900 connects the first through hole 800 and the puncture diaphragm part 700.

[0111] When the atomizing core assembly 200 is not inserted into the first through hole 11214, the following pressure relief channel can be formed using the above method: inner chamber 130 – pressure relief through hole 500 – second sealing channel 400 – pressure relief diaphragm 600 – first sealing channel 300 – puncture diaphragm 700 – connecting tube 900 – first through hole 800 – external environment; when the atomizing core assembly 200 is inserted into the first through hole 11214, the following pressure relief channel can be formed: inner chamber 130 – pressure relief through hole 500 – second sealing channel 400 – pressure relief diaphragm 600 – first sealing channel 300 – puncture tube 250 sequentially passes through the first through hole 800 – connecting tube 900 – puncture diaphragm 700. That is, in some embodiments, when the atomizing core assembly 200 is inserted into the liquid storage assembly 100, the puncture tube 250 passes through the first through hole 800, the connecting tube portion 900 and the puncture membrane portion 700 in sequence and communicates with the first sealing channel 300.

[0112] refer to Figure 2-3 , Figure 6 and Figure 11 In some embodiments, the atomizing tube 220 is also provided with an oil-absorbing chamber 1000 that communicates with the connecting tube 900. The oil-absorbing chamber 1000 contains oil-absorbing cotton 1100. The puncture tube 250 penetrates the oil-absorbing chamber 1000 and can further absorb leaked e-liquid through the oil-absorbing chamber 1000.

[0113] A second aspect of this application provides an atomizer comprising an atomizing cartridge of any of the above embodiments.

[0114] Finally, it should be noted that the technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0115] The above embodiments illustrate only one implementation of the present utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present utility model, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be determined by the appended claims.
