Description

Technical Field

[0001] This utility model relates to the field of electronic atomization technology, and in particular to an atomizing bullet and atomizer. Background Technology

[0002] The core component of an atomizer is the atomizing cartridge. An atomizing cartridge typically includes a coil and a reservoir. Generally, the coil contains a heating element and a liquid guide cotton, the reservoir provides liquid to the guide cotton, and the heating element heats the liquid in the guide cotton to atomize it into inhalable gas for the user.

[0003] In related technologies, leakage of liquid storage tanks is a common problem. For example, when the tank is used again after being left for a period of time, liquid may leak out. As a result, users may easily inhale large droplets or experience aerosol particles due to insufficient atomization, leading to a very poor aerosol taste. In addition, under conditions such as high altitude and low pressure, high temperature and high humidity, the liquid inside the storage tank can be squeezed out, resulting in leakage.

[0004] Therefore, there is an urgent need to provide an atomizing bullet and atomizer to improve its leak-proof effect. Utility Model Content

[0015] In some embodiments, the total flow area of ​​the through holes is smaller than the flow area of ​​the liquid outlet; and / or, the number of through holes is at least two.

[0016] In some embodiments, the liquid storage tank includes:

[0017] The outer casing includes a liquid storage tank with a first opening and an air passage separated from the liquid storage tank. The first opening opens in a first direction, and the air passage extends along the first direction and passes through the liquid storage tank.

[0018] An inner tube assembly, one end of which is inserted into the air passage and sealed to the air passage, the inner tube assembly includes the core cavity, the atomizing core is inserted into the core cavity of the inner tube assembly, and the liquid outlet is opened in the inner tube assembly.

[0019] A sealing plug is provided, with the other end of the inner tube assembly inserted into the sealing plug and sealingly engaging with it. The sealing plug, in conjunction with the inner tube assembly, blocks the first opening to define the liquid storage chamber in conjunction with the liquid storage tank.

[0020] In some embodiments, the inner tube assembly includes:

[0021] A sealing tube, one end of which is sealed and inserted into the airway;

[0022] The inner tube body has one end of the sealing tube inserted into one end of the inner tube body and sealed to the inner tube body. The inner cavity of the inner tube body is the core cavity. The liquid outlet is opened in the inner tube body. The other end of the inner tube body is sealed and inserted into the sealing plug.

[0023] In some embodiments, the inner tube has at least one air inlet groove in its wall, the air inlet groove is connected to the liquid outlet, and the air inlet groove is covered by the sealing tube.

[0024] In some embodiments, the inner tube assembly includes:

[0025] The outer tube has one end sealed and inserted into the airway, and the other end sealed and inserted into the sealing plug. The outer tube includes a flow-limiting wall portion that covers the liquid outlet.

[0026] The inner tube is inserted into the outer tube, the inner cavity of the inner tube is the core cavity, and the liquid outlet is opened in the inner tube.

[0027] A second aspect of this application provides an atomizer comprising the atomizing cartridge described in any of the above embodiments.

[0028] The beneficial effects of this utility model are:

[0029] This utility model relates to an atomizing cartridge comprising a liquid storage chamber and an atomizing core. The liquid storage chamber includes a core cavity, a liquid storage chamber, and a liquid outlet, with the liquid storage chamber communicating with the core cavity through the liquid outlet. The atomizing core is inserted into the core cavity and includes a heating element and liquid-guiding cotton attached to the heating element. The liquid-guiding cotton includes a sealing portion that blocks the liquid outlet, and the heating element includes a heating portion, with the heating portion facing the sealing portion in the opening direction of the liquid outlet. The liquid storage chamber and the core cavity are connected through a single liquid outlet, meaning that liquid is guided to the atomizing core through a series of liquid outlets. Furthermore, the liquid-guiding cotton includes a sealing portion that blocks the liquid outlet, with the heating portion facing the sealing portion in the opening direction of the liquid outlet. Therefore, when the heating portion of the heating element is working, liquid is transmitted from the liquid outlet into the liquid-guiding cotton, ensuring timely liquid supply to the liquid-guiding cotton and preventing the atomizing core from clogging. Since the liquid storage chamber has only one liquid outlet supplying liquid to the liquid-guiding cotton, it can prevent liquid from flowing to the liquid-guiding cotton from the direction opposite to the liquid outlet, thus mitigating leakage. When the heating element is not working, since there is only one liquid outlet for liquid supply, a liquid film forms on the surface of the liquid-guiding cotton when it is saturated. This film can prevent or slow down the continued flow of liquid into the liquid-guiding cotton, thereby reducing leakage. In addition, although outside air can enter the liquid storage chamber through the liquid outlet, when not in use, the liquid film formed on the saturated liquid-guiding cotton can prevent air from entering the liquid storage chamber, which helps to reduce leakage.

The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0046] See Figure 1-3 Some embodiments of this application provide an atomizing cartridge, which includes a liquid storage chamber 1 and an atomizing core 2. The liquid storage chamber 1 includes a core cavity 1222, a liquid storage chamber 14, and a liquid outlet 1221. The liquid storage chamber 14 is connected to the core cavity 1222 through the liquid outlet 1221. The atomizing core 2 is inserted into the core cavity 1222 and includes a heating element 21 and a liquid-guiding cotton 22 attached to the heating element 21. The liquid-guiding cotton 22 includes a sealing portion 221 that blocks the liquid outlet 1221, and the heating element 21 includes a heating portion 211. In the opening direction of the liquid outlet 1221, the heating portion 211 faces the sealing portion 221.

[0047] The advantages of the atomizing bullet provided by some embodiments of this application are as follows: the liquid storage chamber 14 and the core chamber 1222 are connected through a liquid outlet 1221, that is, liquid is guided to the atomizing core 2 through a liquid outlet 1221, and the liquid guiding cotton 22 includes a sealing part 221 that blocks the liquid outlet 1221. In the opening direction of the liquid outlet 1221, the heating part 211 faces the sealing part 221. Therefore, when the heating part 211 of the heating element 21 is working, the liquid outlet 1221 transmits liquid into the liquid guiding cotton 22, which provides timely liquid supply to the liquid guiding cotton 22 and avoids the phenomenon of the atomizing core 2 clogging. Since the liquid storage chamber 1 has only one liquid outlet 1221 for supplying liquid to the liquid guiding cotton 22, it can prevent liquid from flowing out from the back. The liquid flows towards the outlet 1221 to the liquid-guiding cotton 22, alleviating leakage. When the heating part 211 of the heating element 21 is not working, since only one outlet 1221 supplies liquid, a liquid film forms on the surface of the liquid-guiding cotton 22 when it is saturated. This film can prevent or slow down the continued flow of liquid into the liquid-guiding cotton 22, thereby reducing leakage. In addition, although outside air can enter the liquid storage chamber 14 through the outlet 1221, when not in use, the liquid-guiding cotton 22 is saturated, and the liquid film formed on the liquid-guiding cotton 22 can block air from entering the liquid storage chamber 14, making the gas pressure inside the oil storage chamber 14 slightly lower than the gas pressure outside the oil storage chamber 14, thus helping to reduce leakage.

[0048] In some implementations, see Figure 1-3 The liquid outlet 1221 is a square or round hole, which has a simple structure, is easy to process, and has low cost. Furthermore, the liquid outlet 1221 is a square hole. When the square hole comes into contact with the liquid, the liquid can come into contact with the liquid guiding cotton 22 through the middle position of the square hole. Outside air can be introduced through the multiple corners of the square hole. That is, the generated bubbles enter the liquid storage chamber 14 from each corner. Since the formed bubbles are round, the shape of the square hole is not conducive to the retention of bubbles on the square hole. Therefore, it can alleviate the burning phenomenon of the atomizing core 2 caused by the bubbles blocking the square hole and causing the liquid guiding to be unsmooth.

[0049] In some implementations, preferably, see [link to implementation details]. Figure 1-3 The liquid outlet 1221 is square, which is simple in structure, easy to process and low in cost. The square has four square corners, so bubbles can be generated from the four corners and enter the liquid storage chamber 14.

[0050] In some implementations, see Figure 1-3 The flow area of ​​outlet 1221 is 2.6 mm². 2 ~25mm 2The larger the flow area of ​​the liquid outlet 1221, the easier it is to leak liquid; the smaller the flow area, the easier it is for the atomizing core 2 to burn. Experimental studies have shown that the optimal flow area for the liquid outlet 1221 is 2.6 mm. 2 ~25mm 2 The overall effect is good.

[0051] In some embodiments, preferably, the flow area of ​​the liquid outlet 1221 is 3 mm. 2 ~12mm 2 The larger the flow area of ​​the liquid outlet 1221, the easier it is for liquid to leak; the smaller the flow area, the easier it is for the atomizing core 2 to burn. Experimental studies have shown that when the flow area is between 3-12 mm... 2 When the liquid is within the specified range, the pressure difference between the inside and outside of the liquid storage chamber 1 breaks the liquid film and makes it conductive with the atomizing core 2, thus alleviating the phenomenon of dry burning of the heating element 21 during operation, that is, leakage when it is stationary.

[0052] In addition, the heating element 21 includes a heating section 211, which faces the sealing section 221 in the opening direction of the liquid outlet 1221; the liquid-guiding cotton 22 also has a part that is not opposite to the heating section 211, so when the heating section 211 is working, the liquid absorbed by the other parts of the liquid-guiding cotton 22 can be replenished to the part facing the heating section 211 in a timely manner; when the heating section 211 is not working, the part of the liquid-guiding cotton 22 that is not opposite to the heating section 211 can be used to buffer a part of the liquid for replenishment in the next operation.

[0053] In other implementations, see Figure 4-5 The atomizing bullet also includes a flow-limiting structure, which includes a flow-limiting wall located in the liquid storage chamber 14. The flow-limiting wall covers the liquid outlet 1221, and at least one through hole 1231 communicating with the liquid outlet 1221 is provided at a certain position of the flow-limiting wall. The through hole 1231 corresponds to and communicates with the liquid outlet 1221, so that liquid can be supplied in time when the heating element 21 is working, and the flow-limiting effect of the flow-limiting wall can further alleviate liquid leakage; and there is at least a space of the wall thickness of the flow-limiting wall between the through hole 1231 and the liquid outlet 1221, so a liquid film can be formed in this space. When the heating element 211 is working, the liquid film is broken, and the liquid is guided in time, reducing the dry burning of the atomizing core 2. In the static state, the liquid film is not easily broken, so it is beneficial to prevent liquid flow and alleviate the leakage phenomenon. It should be noted that the specific implementation of the flow-limiting structure will be explained in detail in the following specific embodiments.

[0054] In other implementations, see Figure 4-5The total flow area of ​​the through hole 1231 is smaller than that of the outlet 1221. When the pressure difference between the inside and outside of the liquid storage tank 1 is relatively small, the liquid film effectively seals the through hole 1231 due to its smaller size, thus mitigating leakage. When the heating unit 211 is operating and the pressure difference between the inside and outside of the liquid storage tank 1 is relatively large, the liquid film is disrupted, resulting in good liquid guiding effect. In different scenarios, it serves both as a liquid guiding mechanism and as a flow-blocking mechanism to mitigate leakage.

[0055] See Figure 4-5 In some other embodiments, the number of vias 1231 is at least two; preferably, the number of vias 1231 is two.

[0056] For the specific implementation structure of the liquid storage tank 1, see [link to relevant documentation]. Figure 1-3 The liquid storage chamber 1 includes an outer shell 11, an inner tube assembly 12, and a sealing plug 13. The outer shell 11 includes a liquid storage tank 111 with a first opening and an air passage 112 separated from the liquid storage tank 111. The first opening faces a first direction X, and the air passage 112 extends along the first direction X and passes through the liquid storage tank 111. One end of the inner tube assembly 12 is inserted into the air passage 112 and is sealed to it. The inner tube assembly 12 includes a core cavity 1222, an atomizing core 2 is inserted into the core cavity 1222, and a liquid outlet 1221 is opened in the inner tube assembly 12. The other end of the inner tube assembly 12 is inserted into the sealing plug 13 and is sealed to it. The sealing plug 13 cooperates with the inner tube assembly 12 to block the first opening, thereby defining a liquid storage chamber 14 in conjunction with the liquid storage tank 111, thus forming a relatively sealed liquid storage chamber 14. The sealing plug 13 can be made of sealing rubber or the like.

[0057] It should be noted that sealing can be achieved using structures such as sealing rings, sealing gaskets, and sealing sleeves to reduce leakage at the connection.

[0058] For the specific implementation structure of the inner tube assembly 12, see [link to relevant documentation]. In some implementations, see [link to relevant documentation]. Figure 1-3 The inner tube assembly 12 includes a sealing tube 121 and an inner tube body 122. One end of the sealing tube 121 is sealed and inserted into the air passage 112; the other end of the sealing tube 121 is inserted into one end of the inner tube body 122 and is sealed and fitted with the inner tube body 122. The inner cavity of the inner tube body 122 is a core cavity 1222, and the liquid outlet 1221 is opened in the inner tube body 122. The other end of the inner tube body 122 is sealed and inserted into the sealing plug 13. The sealing tube 121 achieves a sealed connection between the inner tube body 122 and the air passage 112, reducing leakage.

[0059] In some implementations, see Figure 1-3The inner tube 122 has at least one air inlet groove 1223 on its wall. The air inlet groove 1223 is connected to the liquid outlet 1221. The air inlet groove 1223 is covered by the sealing tube 121. In this way, external air can be guided through the air inlet groove 1223 to enter the liquid storage chamber 14 through the liquid outlet 1221, thereby balancing the pressure difference between the liquid storage chamber 14 and the external environment.

[0060] In addition, in some other embodiments, see Figure 1-5 The inner tube assembly 12 includes an inner tube body 122 and an outer tube 123, which can be a flow-limiting structure in some embodiments. One end of the outer tube 123 is sealed and inserted into the air passage 112, and the other end of the outer tube 123 is sealed and inserted into the sealing plug 13. The outer tube 123 includes a flow-limiting wall covering the liquid outlet 1221. The flow-limiting wall covers the liquid outlet 1221, and a through hole 1231 communicating with the liquid outlet 1221 is opened at a certain position on the flow-limiting wall. The inner tube body 122 is inserted into the outer tube 123, and the inner cavity of the inner tube body 122 is a core cavity 1222. The liquid outlet 1221 is opened in the inner tube body 122. The through-hole 1231 corresponds to and communicates with the liquid outlet 1221, thus ensuring timely liquid supply when the heating element 21 is operating. The flow-limiting effect of the flow-limiting wall further mitigates leakage. Furthermore, there is at least a space of the flow-limiting wall thickness between the through-hole 1231 and the liquid outlet 1221, allowing a liquid film to form within this space. When the heating part 211 of the heating element 21 operates, the liquid film is disrupted, guiding the liquid away promptly and reducing dry burning of the atomizing core 2. In a static state, the liquid film is less easily disrupted, thus helping to prevent liquid flow and alleviate leakage.

[0061] Of course, in some other embodiments, the flow limiting structure can also be a blocking protrusion fixed or formed on the sealing plug 13. The blocking protrusion has a through hole 1231 that corresponds to and communicates with the liquid outlet 1221, which can also play the role of flow limiting.

[0062] In addition, some embodiments of this application also provide an atomizer that includes the atomizing cartridge of any of the above embodiments.

[0063] 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.

[0064] 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.
