Description

Technical Field

[0001] This application relates to the field of atomizer technology, and in particular to a liquid reservoir and an atomizer. Background Technology

[0002] In current electronic atomizers, the atomizing matrix is ​​a consumable. To increase the liquid capacity and lifespan of the atomizer, a removable liquid reservoir is usually included to allow for timely replenishment of the atomizing matrix. To prevent leakage, a sponge is typically placed inside the liquid reservoir. This sponge absorbs the atomizing matrix and is connected to both the liquid delivery tube and the atomizing component. The liquid delivery tube is also connected to the liquid reservoir, thus supplying e-liquid to the atomizing component. However, the risk of atomizing matrix leakage still exists. Utility Model Content

[0003] In view of the above problems, embodiments of this application are proposed to provide a liquid reservoir and atomizer that overcome or at least partially solve the above problems.

[0004] To address the aforementioned issues, in a first aspect, embodiments of this application disclose a liquid storage cotton, which includes a first liquid storage portion and a second liquid storage portion, wherein the second liquid storage portion is disposed around the outer periphery of the first liquid storage portion; wherein the first liquid storage portion has a first mounting hole and a second mounting hole, the first mounting hole being used to install a liquid guide tube, and the second mounting hole being used to install an atomizing component; the density of the second liquid storage portion is less than the density of the first liquid storage portion.

[0005] In some embodiments, the first liquid storage portion and the second liquid storage portion are integrally formed.

[0006] In some embodiments, the first liquid storage section and the second liquid storage section are each independently provided.

[0007] In some embodiments, both the first liquid storage section and the second liquid storage section have an equal density structure.

[0008] In some embodiments, the first mounting hole and the second mounting hole are arranged on opposite sides of the center of the first liquid storage portion; the density of the first liquid storage portion gradually increases along the direction from the outer periphery of the first liquid storage portion to the center of the first liquid storage portion; the density of the second liquid storage portion gradually increases along the direction from the outer periphery of the second liquid storage portion to the inner periphery of the second liquid storage portion.

[0009] In some embodiments, the density of the first liquid storage section is ρ1, where ρ1 ≤ 0.2 g / cm³. 3 The density of the second liquid storage section is ρ2, where ρ2 ≥ 0.04 g / cm³. 3 .

[0010] In some embodiments, the shape of the cross-section of the first liquid reservoir perpendicular to its thickness direction includes one of elliptical, rectangular, and racetrack-shaped.

[0011] In some embodiments, at least one ventilation groove is provided on the side of the second liquid storage section opposite to the first liquid storage section, and the ventilation groove extends through the thickness direction of the liquid storage cotton.

[0012] In some embodiments, at least one of the ventilation slots is disposed near the first mounting hole.

[0013] Secondly, embodiments of this application disclose an atomizer, including a liquid storage chamber and the aforementioned liquid storage cotton; the liquid storage cotton is disposed within the liquid storage chamber.

[0014] The embodiments of this application have the following advantages:

[0015] In this embodiment, the first mounting hole can be used to install a liquid guide tube, and the second mounting hole can be used to install an atomizing component. The liquid guide tube is used to communicate with the liquid storage bottle. Thus, after the atomizing matrix in the liquid storage bottle is introduced into the first liquid storage section through the liquid guide tube, it can be guided to the atomizing component through the first liquid storage section, thereby achieving liquid supply to the atomizing component. Since the second liquid storage section is arranged around the outer periphery of the first liquid storage section, and the density of the second liquid storage section is less than that of the first liquid storage section, the first liquid storage section has a stronger absorption capacity for the atomizing matrix. Therefore, as the atomizing matrix stored in the first liquid storage section is continuously supplied to the atomizing component, the atomizing matrix stored in the second liquid storage section will flow to the first liquid storage section. Thus, with the cooperation of the first and second liquid storage sections, the risk of atomizing matrix leakage can be reduced. Attached Figure Description

[0036] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] The core concept of this application embodiment is to disclose a liquid storage cotton 10 and an atomizer. The atomizer includes a liquid storage cotton 10 and a liquid storage chamber 40. The liquid storage cotton 10 can be disposed in the liquid storage chamber 40. The liquid storage cotton 10 is used to absorb and store the atomizing matrix 60 in order to prevent the atomizing matrix 60 from leaking.

[0038] In some embodiments, the atomizer further includes an atomizing component 30 and a liquid guide tube 22. A liquid storage bottle 20 is detachably connected to a liquid storage chamber 40 via the liquid guide tube 22. The liquid storage bottle 20 stores the atomizing matrix 60. When the liquid storage bottle 20 and the liquid storage chamber 40 are installed, the liquid storage bottle 20 can supply oil to the liquid storage chamber 40 via the liquid guide tube 22. The atomizing component 30 can be disposed within the liquid storage chamber 40 and can communicate with the liquid storage cotton 10, allowing the liquid storage cotton 10 to supply oil to the atomizing component 30. The atomizing component 30 can heat the atomizing matrix 60 when energized to form an aerosol.

[0039] In this embodiment, the atomizing assembly 30 includes an atomizing tube 31 and a heating element 32 disposed within the atomizing tube 31. Both ends of the atomizing tube 31 are connected to the liquid storage chamber 40. The atomizing tube 31 can be used to isolate the heating element 32 and the atomizing matrix 60. The atomizing tube 31 may be provided with a liquid inlet communicating with the liquid storage chamber 40, allowing the atomizing matrix 60 to flow through the liquid inlet to the heating element 32. When the heating element 32 is energized, it can heat the atomizing matrix 60 to obtain an aerosol. The heating element 32 may be a heating wire or a heating mesh, etc.

[0040] like Figure 1 As shown, the atomizing device includes a housing assembly 50, which includes a mouthpiece 51 and a housing 52 connected to each other. The mouthpiece 51 and the housing 52 can constitute the exterior parts of the atomizing device and can be used to protect the internal components of the atomizing device.

[0041] In this embodiment, some improvements have been made to the structure of the liquid storage cotton 10, thereby improving the oil leakage prevention effect of the atomizer.

[0042] like Figure 2 and Figure 3 As shown, the liquid storage cotton 10 includes a first liquid storage section 11 and a second liquid storage section 12, with the second liquid storage section 12 surrounding the outer periphery of the first liquid storage section 11. The first liquid storage section 11 has a first mounting hole 111 and a second mounting hole 112. The first mounting hole 111 is used to install the liquid guide tube 22, and the second mounting hole 112 is used to install the atomizing component 30. The density of the second liquid storage section 12 is less than the density of the first liquid storage section 11.

[0043] In this embodiment, the first mounting hole 111 can be used to install the liquid guide tube 22, and the second mounting hole 112 can be used to install the atomizing component 30. Thus, after the atomizing matrix 60 in the liquid storage bottle 20 is introduced into the first liquid storage section 11 through the liquid guide tube 22, it can be guided to the atomizing component 30 via the first liquid storage section 11, thereby supplying liquid to the atomizing component 30. Since the second liquid storage section 12 is arranged around the outer periphery of the first liquid storage section 11, and the density of the second liquid storage section 12 is less than that of the first liquid storage section 11, the first liquid storage section 11 has a stronger absorption capacity for the atomizing matrix 60. Therefore, after the atomizing matrix 60 stored in the first liquid storage section 11 is continuously supplied to the atomizing component 30, the atomizing matrix 60 stored in the second liquid storage section 12 will flow to the first liquid storage section 11. Thus, with the cooperation of the first liquid storage section 11 and the second liquid storage section 12, the risk of leakage of the atomizing matrix 60 can be reduced.

[0044] In this embodiment, the liquid storage cotton 10 includes a first liquid storage section 11 and a second liquid storage section 12. The second liquid storage section 12 can be disposed around the outer periphery of the first liquid storage section 11, so that the liquid storage cotton 10 can include two parts. The density of the second liquid storage section 12 is less than the density of the first liquid storage section 11, so that the first liquid storage section 11 has a higher absorption capacity for the atomized matrix 60 than the second liquid storage section 12.

[0045] In some embodiments, the first liquid storage section 11 has a first mounting hole 111 and a second mounting hole 112. The first mounting hole 111 is used to install the liquid guide tube 22, and the second mounting hole 112 is used to install the atomizing component 30. In this way, the atomizing matrix 60 in the liquid storage bottle 20 flows preferentially to the first liquid storage section 11 through the liquid guide tube 22, and then the first liquid storage section 11 guides the atomizing matrix 60 to the atomizing component 30.

[0046] In this embodiment, the second liquid storage section 12 is disposed around the outer periphery of the first liquid storage section 11, and the liquid absorption capacity of the first liquid storage section 11 is stronger than that of the second liquid storage section 12. In this way, after the first liquid storage section 11 supplies liquid to the atomizing component 30, the second liquid storage section 12 can supply liquid to the first liquid storage section 11, thereby reducing the risk of leakage.

[0047] In this embodiment, the second liquid storage section 12 can be a ring-shaped structure, and the inner periphery of the second liquid storage section 12 can be enclosed to form a circular ring, a rectangular ring, or a racetrack shape, etc.

[0048] Specifically, the material of the reservoir cotton 10 can be one or a combination of polyamide, polyethylene terephthalate, polypropylene, and polyethylene. Polyamide's high-temperature resistance and corrosion resistance allow it to operate stably in the heating environment of e-cigarettes, while its insulation and abrasion resistance ensure its safety and durability. Polyethylene terephthalate has advantages such as resistance to oil, grease, dilute acids, dilute alkalis, and most solvents, enabling it to maintain stability in the complex environment of e-cigarettes. Polypropylene has the following advantages: high adsorption capacity; the absorbent cotton made of meltblown polypropylene has a large adsorption capacity, capable of storing more e-liquid; fast adsorption; the fast adsorption speed helps in the rapid absorption and transfer of e-liquid; safe and environmentally friendly, it does not support combustion, does not rot or mold, and leaves little ash after combustion. Polyethylene has the advantages of providing some protection against oily substances; although it does not completely prevent oil penetration, it can resist the erosion of e-liquid to a certain extent.

[0049] In summary, each of the four materials used to prepare the reservoir cotton 10 has its advantages. Polyamide is known for its high-temperature resistance and corrosion resistance, polyethylene terephthalate (PET) excels in oil resistance and temperature stability, polypropylene is favored due to its high adsorption capacity and safety, and polyethylene holds a place in the e-cigarette industry because of its protective effect against oily substances. Therefore, when selecting the material for the reservoir cotton 10, a comprehensive consideration should be made based on specific needs and product characteristics.

[0050] In some embodiments, the first liquid storage section 11 and the second liquid storage section 12 are integrally formed, which simplifies the manufacturing process and processing steps of the liquid storage cotton 10.

[0051] In this embodiment, the first liquid storage section 11 and the second liquid storage section 12 are integrally formed, and the gradient density change can be achieved by adjusting the difference in the number of fiber lines in the first liquid storage section 11 and the second liquid storage section 12.

[0052] like Figure 3 As shown, the area within the dashed line can be the first liquid storage section 11, and the area outside the curve can be the second liquid storage section 12.

[0053] In other embodiments, the first liquid storage section 11 and the second liquid storage section 12 are each independently provided.

[0054] In this embodiment, the first liquid storage section 11 and the second liquid storage section 12 can be prepared separately and then assembled together, which can improve the control of different densities of the first liquid storage section 11 and the second liquid storage section 12, and effectively ensure that the density of the first liquid storage section 11 is greater than the density of the second liquid storage section 12.

[0055] In some embodiments, after the second liquid storage section 12 and the first liquid storage section 11 are prepared respectively, the second liquid storage section 12 is disposed around the outer periphery of the first liquid storage section 11.

[0056] In some embodiments, the first liquid storage section 11 and the second liquid storage section 12 can be of equal density, which can reduce the difficulty of manufacturing the first liquid storage section 11 and the second liquid storage section 12.

[0057] In other embodiments, the first mounting hole 111 and the second mounting hole 112 are arranged on opposite sides of the center of the first liquid storage portion 11; the density of the first liquid storage portion 11 gradually increases along the direction from the outer periphery of the first liquid storage portion 11 to the center of the first liquid storage portion 11; and the density of the second liquid storage portion 12 gradually increases along the direction from the outer periphery of the second liquid storage portion 12 to the inner periphery of the second liquid storage portion 12.

[0058] In this embodiment, the density of the first liquid reservoir 11 gradually increases from its outer periphery to its center, resulting in a gradual density gradient distribution. This strengthens the oil absorption capacity of the central region of the first liquid reservoir 11, thereby improving the reliability of the first liquid reservoir 11 in guiding the atomizing matrix 60 to the atomizing assembly 30. Similarly, the density of the second liquid reservoir 12 gradually increases from its outer periphery to its inner periphery, also resulting in a gradual density gradient distribution. This improves the oil guiding effect of the second liquid reservoir 12 to the first liquid reservoir 11.

[0059] In some embodiments, the maximum density of the second liquid reservoir 12 is less than the minimum density of the first liquid reservoir 11, thereby ensuring the reliability of the second liquid reservoir 12 in replenishing the atomizing matrix to the first liquid reservoir 11 and reducing the risk of oil leakage.

[0060] In some embodiments, the first liquid storage section 11 and the second liquid storage section 12 are each independently provided, and the density of the liquid storage cotton 10 can vary gradually along the inner periphery of the second liquid storage section 12 to the inner periphery of the first liquid storage section 11. In other embodiments, the first liquid storage section 11 and the second liquid storage section 12 are integrally formed, and the density of the liquid storage cotton 10 can gradually vary along the inner periphery of the second liquid storage section 12 to the inner periphery of the first liquid storage section 11.

[0061] In some embodiments, a higher density of the reservoir cotton 10 is not necessarily better. The core principle of the reservoir cotton 10 lies in adsorbing the atomizing matrix through its internal porous structure. From the perspective of core function realization, excessive density of the reservoir cotton 10 can impair its core function. For example, the pores may be compressed, leading to a significant reduction in saturated oil absorption, or the atomizing matrix penetration may be hindered, resulting in a slower oil absorption rate. From a practical perspective, excessive density of the reservoir cotton 10 can also reduce its practicality. For instance, high-density reservoir cotton 10 will be harder and unable to conform to curved device surfaces, leading to oil leakage. Alternatively, the dense fibers of high-density reservoir cotton 10 are prone to burrs during cutting, making it difficult to flexibly adjust the shape according to the leakage range during installation, increasing operational difficulty. From an economic perspective, high density means that more substrate is used for the same volume / area of ​​reservoir cotton 10, but the oil absorption rate decreases due to reduced pore size, significantly increasing the unit oil adsorption cost.

[0062] Therefore, in some embodiments of this application, the density of the first liquid storage section 11 is ρ1, and ρ1 is adjusted to ≤ 0.2 g / cm³. 3 It can be comprehensively considered from the aspects of core functions, practicality and economy, while ensuring that the first liquid storage section 11 has a strong oil absorption capacity.

[0063] In some embodiments, the maximum density of the first liquid reservoir 11 can be 0.2 g / cm³. 3 For example, when the first liquid storage section 11 has a constant density, the density of the first liquid storage section 11 can be 0.2 g / cm³. 3 0.18g / cm 3 0.1g / cm 3 0.08g / cm 3 0.075g / cm 3 or 0.07 g / cm 3 When the first liquid storage section 11 has a gradually changing density, the density range of the first liquid storage section 11 can be 0.15 g / cm³. 3 -0.2g / cm 3 0.1g / cm 3 -0.18g / cm 3 0.07g / cm 3 -0.12g / cm 3 0.065g / cm 3 -0.09g / cm 3 Or 0.07g / cm 3 -0.08g / cm 3 wait.

[0064] In some embodiments, if the density of the liquid storage cotton 10 is too low, the fibers of the liquid storage cotton 10 will be loosely arranged and the internal structure will lack sufficient binding force. The key requirement of the liquid storage cotton 10 is that it "does not leak or run off after adsorption", but if the density of the liquid storage cotton 10 is too low, this function will fail. If the density of the liquid storage cotton 10 is too low, the overall strength of the liquid storage cotton 10 will be insufficient and it will be difficult to withstand the physical action in normal use. Therefore, if the density of the liquid storage cotton 10 is too low, it will directly affect its adsorption stability, durability and actual use effect.

[0065] Therefore, in some embodiments of this application, the density of the second liquid storage section 12 is ρ2, and ρ2 is controlled to be ≥ 0.04 g / cm³. 3 The oil absorption capacity of the second liquid storage section 12 can be comprehensively considered from aspects such as stability, durability and actual use effect, while ensuring that the oil absorption capacity of the second liquid storage section 12 is less than that of the first liquid storage section 11.

[0066] In some embodiments, the minimum density of the second liquid reservoir 12 can be 0.04 g / cm³. 3 For example, when the second liquid storage section 12 has an isodense density, the density of the second liquid storage section 12 can be taken as 0.04 g / cm³. 3 0.045g / cm 3 0.05g / cm 3 0.055g / cm 3 0.06 g / cm 3 or 0.07 g / cm 3 When the second liquid storage section 12 has a gradually changing density, the density range of the second liquid storage section 12 can be 0.04 g / cm³. 3 -0.05g / cm 3 0.045g / cm 3 -0.06g / cm 3 Or 0.05g / cm 3 -0.07g / cm 3 wait.

[0067] In some embodiments of this application, the shape of the cross section of the first liquid storage part 11 perpendicular to its thickness direction includes one of elliptical, rectangular and racetrack-shaped, which makes the shape of the first liquid storage part 11 more diverse and the shape of the first liquid storage part 11 more regular, which is convenient to manufacture.

[0068] like Figure 3 As shown, one case illustrates a racetrack-shaped cross-section of the first liquid storage section 11 perpendicular to its thickness direction; other configurations can be referenced.

[0069] In this embodiment, the outer peripheral shape of the first liquid storage section 11 is adapted to the inner peripheral shape of the second sub-liquid storage section, so that the first liquid storage section 11 and the second liquid storage section 12 can fit tightly together, which can improve the oil guiding effect and reduce the risk of oil leakage. For example, Figure 3 As shown, the cross-sectional shape of the first liquid storage section 11 perpendicular to its thickness direction is racetrack-shaped, and the inner periphery of the corresponding second liquid storage section 12 can be enclosed to form a racetrack-shaped structure.

[0070] In the embodiments of this application, such as Figure 4 As shown, the thickness direction of the first liquid storage section 11 is parallel to... Figure 4 Arrow S1 is parallel to the first mounting hole 111 and the second mounting hole 112, both penetrating the first liquid storage section 11 along the direction of arrow S1.

[0071] In some embodiments of this application, at least one ventilation groove 121 is provided on the side of the second liquid storage section 12 away from the first liquid storage section 11, and the ventilation groove 121 extends through the thickness direction of the liquid storage cotton 10.

[0072] In this embodiment, at least one ventilation groove 121 is provided on the side of the second liquid storage section 12 away from the first liquid storage section 11, so that the ventilation groove 121 is provided on the outer periphery of the second liquid storage section 12. In this way, when the liquid storage cotton 10 is assembled to the atomizer, the ventilation groove 121 forms a ventilation channel between the outer periphery of the second liquid storage section 12 and the inner wall of the liquid storage chamber 40. By ventilating the liquid storage chamber 40, the reliability of the atomizing matrix 60 flowing to the atomizing component 30 can be improved.

[0073] In this embodiment, the nozzle 51 has a suction channel, the liquid storage tank 40 can be provided with an atomizing hole, the atomizing hole can connect the liquid storage tank 40 and the suction channel, and the air exchange channel can be connected to the air guide of the atomizing hole. External gas can enter the atomizing hole from the suction channel and then enter the liquid storage tank 40, so that the air pressure inside and outside the liquid storage tank 40 is balanced, which can improve the smoothness and reliability of the flow of the atomizing matrix 60 to the atomizing component 30.

[0074] In some embodiments, the number of ventilation slots 121 may be one, two, or more, and can be set according to actual needs. This application does not make a specific limitation on this.

[0075] In some embodiments, at least two ventilation slots 121 may be arranged at intervals along the outer periphery of the first liquid storage section 11.

[0076] In this embodiment, the atomizing device may include an atomizer and a liquid storage bottle 20. The atomizer may include a liquid storage chamber 40, which is connected to the liquid storage bottle 20 via a liquid guide tube 22. The liquid guide tube 22 is used to guide the atomizing matrix from the liquid storage bottle 20 into the liquid storage chamber 40. The liquid storage bottle 20 may include a bottle body 21, such as... Figure 5 As shown, the bottle body 21 has a receiving cavity 211 for storing the atomized matrix 60 and a bottle opening 212 communicating with the receiving cavity 211. One end of the liquid guide tube 22 can be installed at the bottle opening 212 of the bottle body 21, and the other end can be inserted into the first mounting hole 111; the liquid guide tube 22 can be used to guide liquid and connect the receiving cavity 211 and the first liquid storage part 11. Wherein, as... Figure 6 As shown, the liquid guide tube 22 can be provided with a vent 221. When the liquid guide tube 22 is installed in the first mounting hole 111, the vent 121 can be connected with the vent 221 to guide air, thereby enabling air exchange in the bottle body 21 and improving the reliability and stability of the atomized matrix 60 flowing out of the bottle body 21.

[0077] In some embodiments of this application, at least one ventilation groove 121 can be set close to the first mounting hole 111. Since the first mounting hole 111 is used to install the liquid guide tube 22, the ventilation groove 121 can be set close to the ventilation hole 221, which can shorten the ventilation path of the liquid storage bottle 20 and ensure the reliability of the flow of the atomized matrix 60.

[0078] In this embodiment, the nozzle 51 has a suction channel, and the liquid storage tank 40 may have an atomizing hole. The atomizing hole can connect the liquid storage tank 40 and the suction channel, and the ventilation channel can be connected to the atomizing hole for air circulation. When the liquid storage bottle 20 supplies liquid into the liquid storage tank 40, the atomizing matrix 60 flows out of the receiving cavity 211, which causes a negative pressure to be generated in the receiving cavity 211. External air can enter the atomizing hole from the suction channel, then enter the receiving cavity 211, and then enter the ventilation hole 221 of the liquid guide tube 22 through the ventilation channel, thereby supplying air to the receiving cavity 211 and balancing the air pressure inside and outside the receiving cavity 211.

[0079] In addition, such as Figure 7 As shown, when the atomizing device is laid flat, if the air pressure or temperature changes and the environment changes, the gas in the containment chamber 211 can be discharged from the ventilation hole 221 to the liquid storage chamber 40 along the direction of arrow S2, then discharged from the atomizing hole to the suction channel, and then discharged to the external environment, thereby depressurizing the containment chamber 211 and achieving the effect of preventing oil leakage.

[0080] In some embodiments, the liquid guide tube 22 is further provided with a first liquid guide hole 222 and a second liquid guide hole 223. The first liquid guide hole 222 and the second liquid guide hole 223 can be arranged at intervals along the circumference of the liquid guide tube 22. Along the axial direction of the liquid guide tube 22, the first liquid guide hole 222 and the second liquid guide hole 223 are located on the same side of the ventilation hole 221, so that the reliability of the atomizing matrix 60 flowing from the first liquid guide hole 222 and the second liquid guide hole 223 to the first liquid storage part 11 can be improved, thereby improving the effect of supplying the atomizing matrix 60 to the atomizing assembly 30.

[0081] In some embodiments, the ventilation hole 221 and the second liquid guiding hole 223 can be connected along the length of the liquid guiding tube 22, which can improve the ease of processing the liquid guiding tube 22.

[0082] In this embodiment, the ventilation hole 221 and the liquid guiding hole 223 can be integrally formed. The ventilation hole 221 and the liquid guiding hole 223 can be obtained by opening a hole in the liquid guiding tube 22 once, which can simplify the process steps of the liquid guiding tube 22.

[0083] In some other embodiments of this application, the first liquid guiding hole 222, the second liquid guiding hole 223, and the venting hole 221 can be set independently.

[0084] In some embodiments, the opening size of the first liquid guiding hole 222 can be greater than or equal to the opening size of the second liquid guiding hole 223, which facilitates the oil passage effect of the first liquid guiding hole 222 and can further ensure that sufficient atomizing matrix 60 can flow to the atomizing component 30.

[0085] In some embodiments, if the opening size of the first liquid guide hole 222 and the second liquid guide hole 223 is too small, the speed at which the atomizing matrix 60 flows out of the liquid storage bottle 20 will be too low. The oil supply speed of the atomizing matrix 60 will be less than its consumption speed, which will result in insufficient oil supply to the atomizing component 30, causing the core to burn and wasting the atomizing matrix 60. In severe cases, it may even damage the atomizing device. Insufficient oil supply will also affect the taste of the atomizing device.

[0086] In some embodiments, the opening size of the first liquid guide hole 222 and the second liquid guide hole 223 is too large, which will cause the atomizing matrix 60 to flow out of the storage bottle 20 too fast. The oil supply rate of the atomizing matrix 60 is greater than its consumption rate, resulting in excessive oil supply and the risk of oil leakage.

[0087] In the embodiments of this application, by specifically defining the opening dimensions of the first liquid guiding hole 222 and the second liquid guiding hole 223, the first liquid guiding hole 222 and the second liquid guiding hole 223 are designed to be of a more suitable size, avoiding the adverse effects caused by being too large or too small. Therefore, in some embodiments of this application, along the axial direction of the liquid guiding tube 22, the extension length of the first liquid guiding hole 222 is L1, 2.5mm≤L1≤4.5mm; along the circumferential direction of the liquid guiding tube 22, the width of the first liquid guiding hole 222 is D1, 1.0mm≤D1≤2.0mm; along the axial direction of the liquid guiding tube 22, the extension length of the second liquid guiding hole 223 is L2, 2mm≤L2≤4.5mm; along the circumferential direction of the liquid guiding tube 22, the width of the second liquid guiding hole 223 is D2, 0.5mm≤D2≤1.5mm.

[0088] For example, the extension length L1 of the first liquid guiding hole 222 can be 2.5mm, 2.8mm, 3mm, 3.5mm, 4mm, 4.5mm, etc. The width D1 of the first liquid guiding hole 222 can be 1.0mm, 1.5mm, 1.55mm, 1.6mm, 1.8mm, 1.9mm, 2mm, etc. In some embodiments, the opening size of the first liquid guiding hole 222 can be 2.5mm*1.0mm, 3.5mm*1.5mm, or 4.5mm*2mm, etc.

[0089] For example, the extension length L2 of the second liquid guiding hole 223 can be 2mm, 2.8mm, 3mm, 3.5mm, 4.0mm, 4.5mm, etc. The width D2 of the second liquid guiding hole 223 can be 0.5mm, 0.8mm, 1.0mm, 1.2mm, 1.4mm, 1.5mm, etc. In some embodiments, the opening size of the second liquid guiding hole 223 can be 2.0mm*0.5mm, 3.5mm*1.0mm, or 4.5mm*1.5mm, etc.

[0090] In some embodiments, if the opening size of the vent 221 is too large or too small, it will disrupt the core requirements of the liquid storage bottle 20 to meet the pressure balance and fluid control requirements, leading to problems such as poor oil discharge, leakage, or malfunction. The core function of the vent 221 is to supply air and maintain stable air pressure within the receiving cavity 211 of the bottle body 21.

[0091] In some embodiments, if the opening size of the vent 221 is too large, it will exceed the air control range, leading to excessive air intake or accidental leakage of the atomizing matrix 60. Specifically, when the opening size of the vent 221 is too large, its ability to block the atomizing matrix will be greatly reduced, and there is a risk that the atomizing matrix 60 will flow out directly from the excessively large vent 221 due to gravity, resulting in leakage; when the opening size of the vent 221 is too large, a large amount of air will rush in rapidly, causing the air pressure inside the receiving cavity 211 to be momentarily higher than the outside, pushing the atomizing matrix 60 to gush out from the first liquid guide hole 222 instead of flowing out at a uniform speed, resulting in an unstable oil output speed of the liquid storage bottle 20; when the opening size of the vent 221 is too large, the volatile components in the atomizing matrix 60 will evaporate rapidly through the air guide, affecting the taste of the generated aerosol.

[0092] In some embodiments, if the opening size of the vent 221 is too small, air may not be able to enter the receiving cavity 211 of the bottle body 21 in time, and the receiving cavity 211 will be under continuous negative pressure, which will hinder the atomizing matrix 60 from flowing out and affect the oil supply effect from the liquid storage bottle 20 to the liquid storage chamber 40. Specifically, this includes: the opening size of the vent 221 is too small, the air supply speed is lower than the outflow speed of the atomizing matrix 60, which causes the negative pressure in the receiving cavity 211 to gradually increase, eventually causing the oil output speed of the atomizing matrix 60 to become slower and slower, or even interrupted; the opening size of the vent 221 is too small, the process of air entering the receiving cavity 211 becomes rapid and unstable, and microbubbles are easily formed near the vent 221 or in the atomizing matrix 60. These bubbles flow to the first liquid guiding hole 222 and block the first liquid guiding hole 222, forming an air resistance; in some cases, when the bottle body 21 is made of soft material, if the vent 221 is too small, the continuous negative pressure in the receiving cavity 211 will cause the bottle body 21 to collapse. The bottle body 21 squeezes the atomizing matrix 60, which will cause the flow of the atomizing matrix 60 to become turbulent, and will also cause damage to the liquid storage bottle 20, shortening its service life.

[0093] In the embodiments of this application, by specifically limiting the opening size of the vent 221, a more suitable size is designed for the vent 221, avoiding the adverse effects caused by it being too large or too small. Therefore, in some embodiments of this application, the width of the vent 221 along the circumference of the liquid guide tube 22 is D3, controlled to be 0.2mm≤D≤0.5mm.

[0094] In some embodiments, the width D of the ventilation hole 221 can be 0.2mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm or 0.5mm, etc.

[0095] In some embodiments, the opening size of the vent 221 along the axial direction of the liquid guide tube 22 is L3, where 1.0 mm ≤ L3 ≤ 2.0 mm. For example, the opening size L3 of the vent 221 can be 1.0 mm, 1.2 mm, 1.5 mm, 1.8 mm, or 2.0 mm, etc.

[0096] In some embodiments, the opening size of the ventilation hole 221 can be 0.3mm*1.5mm or 0.4mm*1.5mm, etc.

[0097] In some embodiments, such as Figure 8 and Figure 9As shown, the atomizing device also includes a sealing element 70, which is sealed to the bottom of the liquid storage chamber 40. The sealing element 70 is provided with a through hole 71. The liquid guide tube 22 passes through the through hole 71. Along the axial direction of the liquid guide tube 22, the ventilation hole 221 includes a first section 2211 and a second section 2212. The first section 2211 is located between the first liquid guide hole 222 and the second section 2212. The first section 2211 is located inside the liquid storage chamber 40, and the second section 2212 is located inside the through hole 71. The second section 2212 is connected to the liquid storage chamber 40 through the through hole 71.

[0098] In this embodiment of the application, the first section 2211 of the ventilation hole 221 can be directly connected to the air guide of the liquid storage tank 40, and the second section 2212 can be connected to the air guide of the liquid storage tank 40 through the through hole 71, which can ensure the stability and reliability of ventilation.

[0099] In this embodiment, the portion of the liquid guide tube 22 with the ventilation hole 221 may have a gap with the inner wall of the through hole 71. This gap is used for ventilation, and it is connected to the liquid storage tank 40 and the second section 2212 of the ventilation hole 221. The ventilation path may include two paths: one path runs from the liquid storage tank 40 sequentially to the first section 2211 of the ventilation hole 221, the liquid guide tube 22, and the liquid storage bottle 20; the other path runs from the liquid storage tank 40 sequentially to the through hole 71, the second section 2212 of the ventilation hole 221, the liquid guide tube 22, and the liquid storage bottle 20.

[0100] In some embodiments, the atomizing device is inverted, with the storage bottle 20 positioned above the storage chamber 40, and the vent 221 positioned above the first liquid guide hole 222 and the second liquid guide hole 223. The flow process of the atomizing matrix includes: after flowing out of the storage bottle 20, the atomizing matrix first enters the liquid guide tube 22, and then flows into the storage chamber 40 from the first liquid guide hole 222 and the second liquid guide hole 223 respectively. The gas flow process includes: some gas in the storage chamber 40 enters the liquid guide tube 22 from the first section 2211 of the vent 221, and then enters the storage bottle 20; some gas in the storage chamber 40 first enters the through hole 71, then enters the liquid guide tube 22 from the second section 2212 of the vent 221, and then enters the storage bottle 20.

[0101] The liquid storage cotton described in this application embodiment has at least the following advantages:

[0102] In this embodiment, the first mounting hole can be used to install a liquid guide tube, and the second mounting hole can be used to install an atomizing component. Thus, the atomizing matrix in the storage bottle can be introduced into the first storage section through the liquid guide tube, and then guided to the atomizing component via the first storage section, thereby supplying liquid to the atomizing component. Since the second storage section is arranged around the outer periphery of the first storage section, and the density of the second storage section is less than that of the first storage section, the first storage section has a stronger absorption capacity for the atomizing matrix. Therefore, as the atomizing matrix stored in the first storage section is continuously supplied to the atomizing component, the atomizing matrix stored in the second storage section will flow to the first storage section. In this way, the cooperation between the first and second storage sections can reduce the risk of atomizing matrix leakage.
