Description

Technical Field

[0001] This application relates to the field of atomization technology, and more particularly to an inhalable atomizing device. Background Technology

[0002] Electronic cigarettes, also known as virtual cigarettes or e-cigarettes, have a flavor similar to, and often more diverse than, traditional cigarettes. They are primarily used for smoking cessation and as a substitute for cigarettes. Currently, electronic cigarettes generally lack a display or monitoring system for e-liquid levels. When the e-liquid runs out, users cannot replenish it promptly, thus affecting the normal use of the e-cigarette. Utility Model Content

[0003] One object of this application is to provide an atomizing device that allows users to easily observe the content of e-liquid.

[0004] This application discloses an atomizing device, including an oil cup, a support, an atomizing core assembly, and a reservoir cotton. The oil cup has a reservoir chamber and a suction port, and includes a transparent area corresponding to at least the reservoir chamber. The support is disposed within the oil cup and located on the side of the reservoir chamber away from the suction port. The support has a lower liquid chamber and a receiving chamber that are isolated from each other. The lower liquid chamber communicates with the reservoir chamber, and the wall of the receiving chamber has a lower oil hole, through which the lower liquid chamber and the receiving chamber communicate. The atomizing core assembly is disposed within the receiving chamber. The reservoir cotton is disposed within the receiving chamber and located between the lower oil hole and the atomizing core assembly, covering the lower oil hole and contacting the atomizing core assembly.

[0005] In this application, the oil cup is provided with a transparent area, which allows users to observe the liquid content in the reservoir through the transparent area, thus improving the user experience; and the liquid storage cotton is provided in the receiving cavity that houses the atomizing core component, which helps to stably supply oil to the atomizing core component.

[0006] In some possible implementations, the atomizing core assembly includes an air passage, a liquid-guiding cotton, and a heating element. The air passage is in contact with the liquid-retaining cotton and has an oil inlet hole that corresponds to the oil outlet hole. The liquid-guiding cotton is disposed inside the air passage and covers the oil inlet hole. The liquid-guiding cotton has a channel, and the heating element is disposed inside the channel and is in contact with the liquid-guiding cotton.

[0007] In some possible implementations, the heating element includes a mesh heating section, which is arranged corresponding to the oil drain hole, so that the e-liquid that seeps into the liquid storage cotton from the oil drain hole can reach the mesh heating section with the least path, which helps to prevent the mesh heating section from dry burning due to lack of oil.

[0008] In some possible implementations, the bottom of the oil hole is lower than the mesh heating element, which helps to ensure sufficient oil supply to the entire mesh heating element and prevents dry burning caused by lack of oil.

[0009] In some possible implementations, there are multiple oil inlet holes, which helps to ensure that the amount of e-liquid immersed in the liquid-guiding cotton through the oil inlet holes is sufficient to prevent the heating element from dry burning.

[0010] In some possible implementations, the area of ​​the oil inlet is 3.7 × 2.2 cm. 2 This helps ensure that the amount of e-liquid absorbed into the guide cotton through the oil inlet is sufficient to prevent the heating element from dry burning.

[0011] In some possible implementations, there are two lower liquid chambers located on opposite sides of the receiving cavity, along a first direction perpendicular to the arrangement direction of the two lower liquid chambers. The diameter of the liquid guiding cotton is 5.1 mm, and the inner diameter of the oil cup is 7.5 mm, so that the atomizing device contains a liquid guiding cotton with a larger size while having a smaller size.

[0012] In some possible implementations, the cavity wall of the receiving cavity has an opening that penetrates the support and is located on at least one side of the receiving cavity in a first direction. The liquid-retaining cotton portion is disposed within and covers the opening. By providing an opening to accommodate the liquid-retaining cotton, the cavity wall of the receiving cavity can have a suitable thickness to provide adequate support, which helps to improve the problem of insufficient space within the receiving cavity for accommodating the liquid-retaining cotton due to the thickness of the cavity wall.

[0013] In some possible implementations, the atomizing device includes a seal disposed between the outer wall of the support and the inner wall of the oil cup and at least around the opening, which helps to prevent the mist generated after atomization in the receiving cavity from leaking through the opening from the connection between the support and the oil cup.

[0014] In some possible implementations, the receiving cavity defines the atomizing cavity, and in the first direction, the thickness of the cavity wall is 0.45 mm. Limiting the cavity wall thickness to a manufacturing process-limited lower limit allows for sufficient space within the receiving cavity to accommodate the liquid storage cotton, while also ensuring good sealing of the atomizing cavity.

[0015] In some possible implementations, the density of the liquid storage cotton is 0.18 g / cm³. 3 This allows the reservoir cotton to absorb more e-liquid, which is beneficial for a stable supply of e-liquid to the atomizer core assembly.

[0016] In some possible implementations, the thickness of the reservoir cotton is 1.2mm, which allows the reservoir cotton to absorb more e-liquid and prevents the atomizer core assembly from dry burning.

[0017] In some possible implementations, the area of ​​the lower oil hole is 4.4 × 1.65 cm. 2 This ensures that the amount of e-liquid immersed in the reservoir cotton through the lower oil hole is sufficient to prevent the atomizer core assembly from dry burning.

[0018] In some possible implementations, the oil cup is a transparent oil cup. Attached Figure Description

[0025] The following specific embodiments are exemplary and not limiting, and are intended to provide a basic understanding of this application, and are not intended to identify key or decisive elements of this application or limit the scope of protection. As long as there is no structural conflict, the technical features mentioned in the various embodiments can be combined in any manner.

[0026] When a component is considered to be "located" on another component, it can be directly on the other component or may also be interspersed with other components. When a component is considered to be "connected" to another component, it can be directly connected to the other component or may also be interspersed with other components.

[0027] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0028] Unless otherwise defined, the term "multiple" in this document, when used to describe the number of components, specifically means that the component is two or more.

[0029] Some embodiments of this application will now be described with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] Please see Figure 1 and Figure 2 One embodiment of this application provides an atomizing device 1, including an oil cup 10, a bracket 20, an atomizing core assembly 30, and a liquid storage cotton 40.

[0031] Please see Figure 3 The oil cup 10 has a suction tube 11 inside and a liquid storage chamber 12 located outside the suction tube 11. One end of the oil cup 10 has a suction port 13, which is connected to the suction tube 11. The liquid storage chamber 12 is used to store volatile liquids, such as e-liquid. The suction tube 11 is used to guide the mist generated after atomization by the atomizer core assembly 30 to the suction port 13 for the user to inhale.

[0032] The oil cup 10 includes a transparent area, which is provided at least corresponding to the liquid storage cavity 12, allowing the user to observe the liquid content within the cavity 12 through the transparent area. In some embodiments, the oil cup 10 is partially translucent, for example, a portion of the oil cup 10 is made of a translucent material. In another embodiment, the oil cup 10 is light-transmitting, meaning it is a translucent oil cup. The oil cup 10 may be made of acrylic.

[0033] Please see Figure 2 and Figure 3 The bracket 20 is detachably installed inside the oil cup 10 and located on the side of the liquid storage chamber 12 opposite to the suction port 13. In this embodiment, the bracket 20 is housed within the liquid storage chamber 12. The outer wall of the bracket 20 can be tightly joined with the cavity wall of the liquid storage chamber 12 to prevent liquid in the liquid storage chamber 12 from leaking from the connection between the bracket 20 and the oil cup 10. The bracket 20 has a lower liquid chamber 21 and a receiving cavity 22 that are isolated from each other. The lower liquid chamber 21 communicates with the liquid storage chamber 12. The cavity wall of the receiving cavity 22 has a lower oil hole 221, and the receiving cavity 22 communicates with the lower liquid chamber 21 through the lower oil hole 221. The lower liquid chamber 21 penetrates the surface of the bracket 20 facing the oil cup 10, and the lower oil chamber 21 is directly connected to the liquid storage chamber 12, allowing the e-liquid in the liquid storage chamber 12 to flow directly into the lower oil chamber 21. The receiving cavity 22 extends through the two surfaces of the support 20 facing and away from the oil cup 10. The suction tube 11 is inserted into the receiving cavity 22 and tightly joined to the cavity wall of the receiving cavity 22 to prevent liquid in the storage cavity 12 from entering the receiving cavity 22 from the connection between the suction tube 11 and the receiving cavity 22.

[0034] In some embodiments, the stent 20 is formed by injection molding. The material of the stent 20 may include at least one of nylon polyamide (PA), polycarbonate (PC), polyethylene (PE), polyoxymethylene (POM), polypropylene (PP), polystyrene (PS), thermoplastic elastomer (TPE), or thermoplastic polyurethane (TPU).

[0035] Please see Figure 3The atomizer core assembly 30 is disposed within the receiving cavity 22. The atomizer core assembly 30 heats the e-liquid within the receiving cavity 22, and the atomized e-liquid flows through the suction tube 11 to the suction port 13. A reservoir cotton 40 is disposed within the receiving cavity 22 and located between the lower oil hole 221 and the atomizer core assembly 30. The reservoir cotton 40 covers the lower oil hole 221 and contacts the atomizer core assembly 30. The reservoir cotton 40 absorbs the e-liquid flowing from the lower oil hole 221 into the receiving cavity 22 and guides the e-liquid to the atomizer core assembly 30. The reservoir cotton 40 surrounds the atomizer core assembly 30 to evenly supply e-liquid to all parts of the atomizer core assembly 30. The reservoir cotton 40 is tightly fitted to the cavity wall of the receiving cavity 22 to prevent e-liquid in the lower oil hole 21 from flowing directly into the receiving cavity 22. The reservoir cotton 40 surrounding the atomizer core assembly 30 within the receiving cavity 22 facilitates a stable e-liquid supply to the atomizer core assembly 30.

[0036] In some embodiments, the density of the liquid storage cotton 40 is 0.18 g / cm³. 3 The density of the currently used liquid storage cotton 40 is generally 0.07 g / cm³. 3 In this application, the density of the liquid storage cotton 40 is set to 0.18 g / cm³. 3 This can increase the amount of e-liquid absorbed by the reservoir cotton 40, preventing the atomizing core assembly 30 from dry burning.

[0037] In some embodiments, the thickness of the reservoir cotton 40 is 1.2 mm, which allows the reservoir cotton 40 to absorb enough e-liquid to prevent the atomizer core assembly 30 from dry burning.

[0038] In some embodiments, the oil outlet 221 is generally rectangular, and the area of ​​the oil outlet 221 is 4.4 × 1.65 cm. 2 This ensures that the amount of e-liquid immersed in the reservoir cotton 40 through the lower oil hole 221 is sufficient to prevent the atomizer core assembly 30 from dry burning.

[0039] Please see Figure 3 The atomizing core assembly 30 includes an airway tube 31, a liquid-guiding cotton 32, and a heating element 33. The airway tube 31 is located between the liquid-retaining cotton 40 and the liquid-guiding cotton 32 and communicates with the suction tube 11. The airway tube 31 is in contact with the liquid-retaining cotton 40. The airway tube 31 has an oil inlet 311, which corresponds to the lower oil outlet 221. The liquid-guiding cotton 32 is located inside the airway tube 31 and covers the oil inlet 311; the portion of the liquid-guiding cotton 32 covering the oil inlet 311 is in contact with the liquid-retaining cotton 40. The liquid-guiding cotton 32 has a channel 321, and the heating element 33 is located within the channel 321 and in contact with the liquid-guiding cotton 32. E-liquid absorbed by the liquid-retaining cotton 40 seeps into the liquid-guiding cotton 32, and the heating element 33 heats and atomizes the e-liquid absorbed by the liquid-guiding cotton 32. The atomized e-liquid flows out from the suction port 13 after passing through the channel 321 and the suction tube 11.

[0040] In some embodiments, the liquid-guiding cotton 32 can be made of porous fiber materials such as fiber cotton, non-woven fabric, linen, and chemical fiber fabric. The above-mentioned porous fiber materials all have good oleophilicity and oil-locking properties. Their small pore size and large porosity make the atomized e-liquid more delicate, with full sweetness and aroma, which is conducive to improving the user experience.

[0041] Please see Figure 3 The heating element 33 includes a mesh heating section 331, which is provided corresponding to the oil outlet 221. This allows the e-liquid that seeps into the liquid storage cotton 40 from the oil outlet 22 to reach the mesh heating section 331 with the least path. This helps prevent the mesh heating section 331 from running out of oil during the heating process due to insufficient oil supply, which could cause dry burning and a burnt taste.

[0042] In some embodiments, the heating element 33 can be made of metals such as chromium, titanium, nickel-chromium alloy, stainless steel, or iron-chromium-nickel alloy. The heating element 33 can be made of a metal sheet. Specifically, the heating element 33 can be a perforated metal sheet with a specific mesh pattern formed by a combination of processes such as rolling, stamping, and etching.

[0043] Please see Figure 3 The bottom of the oil hole 22 is lower than the mesh heating element 331, which helps to ensure sufficient oil supply to the entire mesh heating element 331 and prevents dry burning caused by lack of oil.

[0044] Please see Figure 3 The top of the lower oil hole 22 is higher than the mesh heating element 331, which helps to ensure sufficient oil supply to the entire mesh heating element 331 and prevents dry burning caused by insufficient oil. In this embodiment, when viewed along the direction perpendicular to the axis Z of the atomizing device 1, the orthographic projection of the mesh heating element 331 is located within the orthographic projection of the lower oil hole 22, which ensures sufficient oil supply to the entire mesh heating element 331.

[0045] Please see Figure 3 The bottom of the oil inlet hole 311 is lower than the mesh heating element 331, and the top of the oil inlet hole 311 is higher than the mesh heating element 331. This helps to ensure sufficient oil supply to the entire mesh heating element 331 and prevent dry burning caused by lack of oil.

[0046] Please see Figure 2 The number of oil inlet holes 311 is multiple, and the multiple oil inlet holes 331 are evenly arranged around the liquid guiding cotton 32. In this embodiment, the number of oil inlet holes 311 is four. In other embodiments, the number of oil inlet holes 311 can be two, three, or more than four. Providing multiple oil inlet holes 311 is beneficial to ensure that the amount of e-liquid immersed in the liquid guiding cotton 32 through the oil inlet holes 311 is sufficient to prevent the heating element 33 from dry burning.

[0047] In some embodiments, the oil inlet 311 is generally rectangular, and the area of ​​the oil inlet 311 is 3.7 × 2.2 cm. 2 This ensures that the amount of e-liquid that is immersed in the liquid-guiding cotton 32 through the oil inlet 311 is sufficient to prevent the heating element 33 from dry burning.

[0048] Please see Figure 2 and Figure 3 There are two lower liquid chambers 21 and two lower oil holes 221. The two lower liquid chambers 21 are located on opposite sides of the receiving cavity 22, and each lower liquid chamber 21 is connected to the receiving cavity 22 through a lower oil hole 221. The two lower liquid chambers 21 are arranged in a direction perpendicular to the axial direction Z of the atomizing device 1. In the first direction Y, which is perpendicular to the arrangement direction X of the two lower liquid chambers 21, the inner diameter of the oil cup 10 is 7.5 mm, and the outer diameter of the liquid guiding cotton 32 is 5.1 mm. The inner diameter of the oil cup 10 refers to the distance between the cavity wall of the liquid storage cavity 12 and the central axis of the oil cup 10 in the first direction Y. The outer diameter of the liquid guiding cotton 32 refers to the distance between the outer surface of the liquid guiding cotton 32 in the first direction Y. In this embodiment, the cross-section of the oil cup 10 perpendicular to the axial direction Z of the atomizing device 1 is approximately elliptical. The arrangement direction X of the two lower liquid chambers 21 is parallel to the major axis of the ellipse, and the first direction Y is parallel to the minor axis of the ellipse. When the inner diameter of the oil cup 10 is 7.5mm, the size of the atomizing device 1 in the first direction Y is relatively small, making it convenient for users to use. When the outer diameter of the liquid guiding cotton 32 is 5.1mm, the size of the liquid guiding cotton 32 is relatively large, and the liquid guiding cotton 32 can store more e-liquid, which is conducive to increasing the amount of mist produced and improving the user experience.

[0049] In some embodiments, the thickness of the cavity wall of the receiving cavity 22 along the first direction Y is appropriate, for example, 1 mm, which helps to give the support 20 appropriate support strength in the first direction Y.

[0050] Please see Figure 2 and Figure 4 The cavity wall of the receiving cavity 22 has an opening 222, and the opening 222 and the lower oil hole 221 are located on different sides of the receiving cavity 22. The opening 222 is located on at least one side of the receiving cavity 22 in the first direction Y. The opening 222 penetrates the support 20, and the receiving cavity 22 communicates with the outside of the support 20 through the opening 222. The liquid storage cotton 40 is partially disposed in the opening 222 and covers the opening 222. The opening 222 and the receiving cavity 22 define the atomizing chamber. When the cavity wall of the receiving cavity 22 has a suitable thickness (e.g., 1 mm) to provide suitable support strength, providing the opening 222 on the cavity wall of the receiving cavity 22 and disposing of the liquid storage cotton 40 in the opening 222 can improve the problem of insufficient space in the receiving cavity 22 for accommodating the liquid storage cotton 40 due to the influence of the cavity wall thickness of the receiving cavity 22.

[0051] Please see Figure 2 and Figure 4 There are two openings 222, which are arranged along the first direction Y. Placing the openings 222 on both sides of the receiving cavity 22 in the first direction Y helps to improve the problem that the receiving cavity 22 cannot accommodate a liquid storage cotton 40 with a suitable size (e.g., an outer diameter of 5.1 mm) due to insufficient space in the receiving cavity 22 in the first direction Y.

[0052] In some embodiments, the outer wall of the support 20 is tightly joined to the inner wall of the oil cup 10, which helps to prevent the mist generated after atomization in the receiving cavity 22 from leaking out of the connection between the support 20 and the oil cup 10 through the opening 222.

[0053] Please see Figure 2 and Figure 4 The atomizing device 1 includes a seal 50, which is disposed between the outer wall of the support 20 and the inner wall of the oil cup 10 and at least surrounds the opening 222. This helps to prevent the mist generated after atomization in the receiving cavity 22 from leaking through the opening 222 from the connection between the support 20 and the oil cup 10. The seal 50 can be made of silicone.

[0054] Please see Figure 2 and Figure 3 The sealing element 50 is located between the suction tube 11 and the cavity wall of the receiving cavity 22, which helps to prevent the mist generated after atomization in the receiving cavity 22 from leaking from the connection between the suction tube 11 and the bracket 20.

[0055] Please see Figure 2 and Figure 3 The atomizing device 1 includes a base 60, a mounting base 70, and a fixing member 80. The base 60 is detachably mounted on the side of the bracket 20 away from the suction tube 11 and covers the end of the receiving cavity 22 away from the suction tube 11. Specifically, the base 60 is partially inserted into the receiving cavity 22. The mounting base 70 is detachably mounted on the side of the oil cup 10 away from the suction port 13. Specifically, the mounting base 70 is partially inserted into the oil cup 10. The connecting member 80 is provided on the mounting base 70 and connected to the base 60. Please see Figure 5 and Figure 6In another embodiment, the cavity wall of the receiving cavity 22 does not have an opening penetrating the support 20 in a direction perpendicular to the axial direction Z of the atomizing device 1, and the receiving cavity 22 defines the atomizing cavity. That is, in the direction perpendicular to the axial direction Z of the atomizing device 1, the support 20 is located between the liquid storage cotton 40 and the oil cup 10, and the liquid storage cotton 40 is isolated from the oil cup 10 by the support 20. In this embodiment, in the first direction Y, the liquid storage cotton 40 is isolated from the oil cup 10 by the support 20. Along the first direction Y, the thickness of the cavity wall of the receiving cavity 22 is 0.45 mm. 0.45 mm is the lower limit of the thickness that the support 20 can achieve when formed by injection molding. Compared with the conventional thickness of the cavity wall of the receiving cavity 22, by reducing the thickness of the cavity wall of the receiving cavity without an opening penetrating the support 20, the receiving cavity 22 can have sufficient space in the first direction Y to accommodate the liquid storage cotton 40. The conventional thickness of the cavity wall of the receiving cavity 22 refers to the fact that the cavity wall of the receiving cavity 22 with this conventional thickness has suitable support strength, such as 1 mm. Furthermore, the cavity wall of the receiving cavity 22 has no openings, and the atomizing cavity has good sealing performance.

[0056] Those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the spirit and essence of this application fall within the scope of this application's disclosure.
