Description

Technical Field

[0001] This utility model relates to the field of electronic atomization technology, specifically to an atomization device. Background Technology

[0002] Atomizing devices, also known as electronic cigarettes, work by atomizing e-liquid for inhalation. Currently, condensation forms at the connection between the vapor and the mouthpiece in these devices, affecting the vaping experience.

[0003] Currently, the common technical solution to this problem is to install a solid cotton-like material at the connection between the upper part of the oil tank flue and the mouthpiece to store condensate. However, due to the influence of traditional processing methods, this type of solid cotton can usually only be processed into a block structure with flat ends. This type of solid cotton can only be assembled in a regular space, while the mouthpiece is usually an irregular space, which makes it impossible to effectively utilize the space inside the mouthpiece, resulting in a great waste of design space. At the same time, the amount of condensate that a fixed volume of solid cotton can store is limited, and for some products with a large number of puffs, it is difficult to completely avoid condensation during later suction. Utility Model Content

[0004] This invention provides an atomizing device to solve the problems of low space utilization of solid cotton and limited storage of condensate.

[0005] In one embodiment, an atomizing device is provided, comprising:

[0006] The shell has an atomizing air passage;

[0007] A suction nozzle, mounted on the housing, having a suction nozzle air passage communicating with an atomizing air passage; the suction nozzle and the housing forming a receiving cavity, the receiving cavity communicating with the suction nozzle air passage and / or the atomizing air passage; and

[0008] A liquid-absorbing element is disposed in the receiving cavity. The liquid-absorbing element is used to absorb liquid in the mouthpiece air passage and / or the atomizing air passage. At least a portion of the liquid-absorbing element is configured to expand in volume after absorbing liquid.

[0009] In one embodiment, in the suction direction, the liquid suction member is disposed upstream of the receiving cavity, and the liquid suction member is configured to expand in volume downstream of the receiving cavity.

[0010] In one embodiment, the suction nozzle includes a mouthpiece and an airway tube, the airway tube being located inside the mouthpiece, the channel within the airway tube forming the suction nozzle airway, the area between the mouthpiece and the airway tube forming the receiving cavity, and the liquid suction element having a through hole for airflow communication with the airway tube.

[0011] In one embodiment, the airway tube is provided with a suction port, and the accommodating cavity is connected to the mouthpiece airway through the suction port; the volume of the accommodating cavity at the end near the suction port is greater than the volume of the accommodating cavity at the end away from the suction port.

[0012] In one embodiment, the liquid-absorbing element is configured to expand in volume after absorbing liquid; and / or, the liquid-absorbing element can expand to fill the accommodating cavity.

[0013] In one embodiment, the liquid-absorbing element includes at least one of compressed cotton, compressed nonwoven fabric, polyurethane foam, sodium polyacrylate, gelatin, compressed paper, and plant fiber.

[0014] In one embodiment, the nozzle is a transparent or semi-transparent structure.

[0015] In one embodiment, the liquid-absorbing element is a dyed structure, and the dyed structure does not change color before and after liquid absorption.

[0016] In one embodiment, the outer surface of the liquid-absorbing element facing the nozzle is provided with a shielding layer, which is used to cover the color change of the liquid-absorbing element before and after liquid absorption.

[0017] In one embodiment, a shielding member is provided on the side of the liquid-absorbing member facing the suction nozzle, and the shielding member is used to cover the color change of the liquid-absorbing member before and after liquid absorption.

[0018] According to the atomizing device of the above embodiment, since at least a portion of the liquid-collecting (condensate) suction element is configured to expand in volume after absorbing the liquid, the suction element can expand to a larger volume to absorb more condensate, thereby increasing the condensate storage capacity and preventing condensate from entering the user's mouth and flowing back into the atomizing chamber. Furthermore, the suction element is an expandable flexible structure, allowing it to expand and deform in any space without being limited by the nozzle structure. This allows full utilization of the regular and irregular spaces inside the nozzle, increasing the liquid storage capacity of the suction element. Consequently, the impact of condensate can be avoided during the later suction of some products with large mouth openings. Attached Figure Description

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0035] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0036] The component designations used in this document, such as "first" and "second," are merely for distinguishing the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages). The terms "upper end" and "lower end" in this document refer to the orientation of the atomizing device during inhalation.

[0037] In one embodiment, an atomizing device is provided. This atomizing device is an e-liquid atomizing device that heats e-liquid to form atomized gas for the user to inhale. The atomizing device has a liquid-collecting component installed at the connection between the mouthpiece and the atomizing airway. The liquid-collecting component is used to collect condensate formed in the atomizing airway and the mouthpiece to prevent condensate from entering the user's mouth or flowing down into the heating element.

[0038] This atomizing device improves the liquid suction component at the connection between the mouthpiece and the atomizing airway by designing it as an expandable, flexible structure. This expandable component expands and changes shape with the increase in liquid intake. This design increases the capacity of the liquid suction component to store condensate, ensuring that all condensate is collected and improving the sipping experience. Furthermore, the expandable component can expand both regularly and irregularly, allowing it to fully utilize the regular and irregular spaces within the mouthpiece. For example, it can expand to fill the entire mouthpiece space, eliminating the need for a larger space within the mouthpiece or housing to accommodate a larger liquid suction component, thus increasing its storage capacity and liquid capacity. In other words, by incorporating an expandable component into the existing small-volume mouthpiece and housing, the liquid suction component can adaptively utilize the regular and irregular spaces within the mouthpiece to expand its storage space, thereby increasing the amount of condensate stored and improving the sipping experience.

[0039] Please refer to Figures 1 to 5 The atomizing device in this embodiment mainly includes a housing 1, a nozzle 2, and a liquid suction element 3. The nozzle 2 is installed at one end of the housing 1. For example, the nozzle 2 and the housing 1 are connected by a snap-fit ​​structure. The nozzle 2 has a nozzle air passage 23, through which the aerosol generated by the atomizing device is delivered to the user's mouth.

[0040] The housing 1 has an installation cavity, which houses components such as the atomizing assembly 4, the liquid storage cavity 5, the circuit board 6, and the battery 7. For example, the housing 1 can be a single integrated structure, or it can be assembled from multiple sub-housings (not shown).

[0041] In one exemplary embodiment, the atomizing component 4 includes an atomizing tube 41, a liquid storage substrate 42, and a heating element 43. The atomizing tube 41 is installed inside the housing 1, and an atomizing air passage 411 is formed inside the atomizing tube 41. The liquid storage substrate 42 can be a liquid storage structure such as liquid storage cotton or liquid storage ceramic. The liquid storage substrate 42 is installed inside the atomizing tube 41 and can be an annular structure, such as a cylindrical structure. The middle part of the liquid storage substrate 42 has an air passage for air circulation.

[0042] In one embodiment, the atomizing tube 41 may be omitted, and the atomizing assembly 4 includes a liquid storage substrate 42 and a heating element 43. The liquid storage substrate 42 has a hollow channel (i.e., the atomizing air passage 411 shown in the figure), and the heating element 43 is disposed in the hollow channel.

[0043] In one embodiment, the circumferential side of the atomizing tube 41 is provided with a liquid guiding hole (not shown) communicating with the liquid storage chamber 5. The liquid storage chamber 5 is used to store liquid atomizing matrix, which can enter the liquid storage substrate 42 through the liquid guiding hole of the atomizing tube 41. The heating element 43 is installed on the inner side of the liquid storage substrate 42. The heating element 43 can be a resistance heating structure, such as a metal heating mesh or a metal heating spiral, etc. The heating element 43 can convert electrical energy into heat energy. The heat energy generated by the heating element 43 can heat and atomize the atomizing matrix adsorbed in the liquid storage substrate 42. After heating and atomizing, the atomizing matrix can be discharged from the atomizing channel for the user to inhale.

[0044] In one embodiment, the atomizing matrix is ​​a liquid atomizing matrix, the main components of which include propylene glycol, glycerol, flavoring and nicotine.

[0045] In one embodiment, the circuit board 6 and the battery 7 are installed inside the housing 1, and can be fixed inside the housing 1 by a mounting bracket. The circuit board 6 is electrically connected to the heating element 43 and the battery 7 respectively. The circuit board 6 is used to control the heating time and heating power of the heating element 43 to meet the tasting needs of different usage scenarios. The battery 7 is an energy storage component, used to provide electrical energy for the operation of the circuit board 6 and the heating element 43.

[0046] In one exemplary embodiment, the atomizing device is a disposable product, the liquid storage chamber 5 may not have an injection port, and the battery 7 may not have a corresponding charging port.

[0047] In one exemplary embodiment, the atomizing device can also be configured as a reusable product. A liquid inlet is provided on the side or top of the housing 1, communicating with the liquid storage chamber 5, and a removable liquid plug is installed at the inlet. The liquid storage chamber 5 can also be configured as a removable liquid tank structure. The liquid inlet and the removable liquid tank allow the atomizing device to be replenished with atomizing matrix, enabling extended use. A charging port can be provided on the side or bottom of the housing 1, and the circuit board 6 is electrically connected to the charging port, allowing the user to recharge the battery 7 through the charging port, thereby improving the battery life of the atomizing device.

[0048] In one embodiment, the side or bottom of the housing 1 is also provided with an air inlet, which is connected to the atomizing air passage 411 and is used to conduct heat into the atomizing air passage 411.

[0049] The nozzle 2 is installed on the upper end of the housing 1. The nozzle 2 can be fixed to the upper end of the housing 1 by means of snap-fit, adhesive, screw connection, etc. The nozzle 2 has a nozzle air passage 23, which is connected to the atomizing air passage 411 of the housing 1. The aerosol formed by heating and atomizing in the atomizing air passage 411 can be discharged from the nozzle air passage 23 to the user's mouth.

[0050] The mouthpiece 2 includes a mouthpiece shell 21 and an airway tube 22. The mouthpiece shell 21 has a flat structure. The end of the mouthpiece shell 21 closer to the housing 1 has a relatively larger volume, while the end of the mouthpiece shell 21 further away from the housing 1 has a relatively smaller volume. The end of the mouthpiece shell 21 further away from the housing 1 is the end used by the user for inhalation, so it needs to be relatively smaller for user convenience. The end of the mouthpiece shell 21 closer to the housing 1 is used for connection with the housing 1, and its relatively larger volume can improve the stability of the connection between the mouthpiece shell 21 and the housing 1, and at the same time, it can increase the internal volume of the mouthpiece 2. The airway tube 22 is disposed inside the mouthpiece shell 21 and passes through the mouthpiece shell 21, forming a mouthpiece airway 23 within the airway tube 22. The mouthpiece 2 is installed at the upper end of the housing 1, and the mouthpiece airway 23 is connected to the atomizing airway 411.

[0051] The nozzle 2 can be an integrated structure, with the nozzle shell 21 and the airway tube 22 molded as one piece. The nozzle 2 can also be a spliced ​​installation structure, with the nozzle shell 21 and the airway tube 22 fixed by snap-fit, adhesive or other methods.

[0052] In one embodiment, the area between the mouthpiece 21 and the airway tube 22 forms a receiving cavity 24, and the lower end of the receiving cavity 24 is closed by the housing 1. That is, the mouthpiece 2 and the housing 1 together form a relatively closed receiving cavity 24. The receiving cavity 24 can be a regular cavity or an irregular cavity. A regular cavity refers to a cavity with conventional shapes such as annular, cylindrical, square, and conical, while an irregular cavity refers to a cavity other than conventional cavities such as annular, cylindrical, square, and conical. The volume of different parts of an irregular cavity varies. Figure 1The cavity 24 shown is an irregular cavity. The cavity 24 is similar in shape to the mouth shell 21. The volume of the cavity 24 is smaller at the upper end than at the lower end.

[0053] In one embodiment, the airway tube 22 is provided with a liquid suction port 221 at one end near the atomizing airway 411. The liquid suction port 221 is connected to the connection between the mouthpiece airway 23 and the atomizing airway 411. That is, the liquid suction port 221 is connected to both the mouthpiece airway 23 and the atomizing airway 411. After the aerosol condenses, it tends to adhere to the inner wall of the airway tube 22 and flow downward along the inner wall. The setting of the liquid suction port 221 does not affect the delivery of aerosol to the user, and at the same time, it can prevent the condensate from flowing back.

[0054] refer to Figure 3 The suction port 221 is located at the lowest end of the airway tube 22; in other embodiments, the suction port may be moved upward.

[0055] In one embodiment, the liquid suction member 3 is installed within the receiving cavity 24. The liquid suction member 3 can absorb the condensate formed in the nozzle air passage 23 and the atomizing air passage 411 through the liquid suction port 221. The liquid suction port 221 can be a structure composed of multiple liquid suction holes, for example, the liquid suction port 221 can be a fence-like or mesh-like structure. This arrangement can effectively block the liquid suction member 3, preventing part of the liquid suction member 3 from extending into the nozzle air passage 23 and / or the atomizing air passage 411 and blocking the air passages.

[0056] In one embodiment, at least a portion of the absorbent element 3 is configured to expand in volume upon absorbing liquid. The absorbent element 3 is made of a material that expands upon absorbing liquid, which is a known material, such as foam, cotton cloth, etc. The absorbent element 3 can be made in different forms and may include at least one of compressed cotton, compressed nonwoven fabric, polyurethane foam, sodium polyacrylate, gelatin, compressed paper, and plant fibers. For example, the absorbent element 3 can be compressed cotton, or it can be a combination of compressed cotton and gelatin.

[0057] In the suction direction, the liquid suction member 3 is located upstream of the receiving cavity 24, and is configured to expand downstream of the receiving cavity 24. That is, the liquid suction member 3 is located at the lower end of the receiving cavity 24, and expands upward after absorbing condensate. Positioning the liquid suction member 3 downstream of the receiving cavity 24, close to the suction port 221, facilitates its ability to collect condensate. Furthermore, when the atomizing device is in use, the liquid suction member 3 being located at the lower end of the receiving cavity 24 improves the stability of its installation.

[0058] The liquid suction component 3 has a through hole 31 in the middle, and the air passage tube 22 passes through the through hole 33 of the liquid suction component 3. The through hole 33 of the liquid suction component 3 is connected to the suction nozzle air passage 23 in the air passage tube 22. The through hole 33 of the liquid suction component 3 forms an airflow avoidance structure.

[0059] Please refer to Figure 3 The initial state of the liquid-absorbing component 3 (the state before liquid absorption) can be made into a regular shape, such as a disc or a cube. Please refer to [reference needed]. Figure 4 The liquid-absorbing component 3 expands and unfolds after absorbing condensate through the liquid-absorbing port 221; the more condensate absorbed, the larger the volume of expansion and unfolding. Figure 5 As shown, it can eventually expand to fill the entire accommodating cavity 24, and the liquid suction element 3 eventually expands to form an irregular shape. By using the expandable and deformable liquid suction element 3, the spatial volume of the accommodating cavity 24 can be reused to maximize the absorption of condensate.

[0060] like Figure 4 As shown, in one embodiment, the amount of condensate absorbed by the liquid suction element 3 in the disposable atomizing device is less than the volume of the accommodating cavity 24. That is, the liquid suction element 3 has design redundancy, and the liquid suction element 3 does not expand to fill the accommodating cavity 24 when the atomizing device reaches the end of its service life. With this setting, it can be ensured that the atomizing device can completely absorb the condensate during use, thus ensuring the taste of the product.

[0061] In one embodiment, the maximum expansion volume of the suction member 3 can also be less than the total volume of the receiving cavity 24. For example, the maximum expansion volume of the suction member 3 is greater than half the total volume of the receiving cavity 24 but less than the total volume of the receiving cavity 24. Compared to a suction member 3 with a fixed volume, the capacity of the suction member 3 can be increased to collect more condensate.

[0062] In one embodiment, the liquid-absorbing member 3 is configured to expand in volume after absorbing liquid, so that the liquid-absorbing member 3 can expand in any direction to adapt to the irregular accommodating cavity 24. That is, the liquid-absorbing member 3 has better compatibility and can expand to form any shape to increase the adsorption capacity.

[0063] In one embodiment, the liquid-absorbing member 3 can also be configured such that part of it expands after absorbing liquid, while the rest is configured as a non-expandable structure. For example, the upper end of the liquid-absorbing member 3 is configured to expand after absorbing liquid, while the lower end is configured as a non-expandable structure. In the initial state (unabsorbed state), the liquid-absorbing member 3 is installed in the receiving cavity 24, with the lower end of the liquid-absorbing member 3 in contact with the housing 1. The space above the liquid-absorbing member 3 is the remaining space of the receiving cavity 24. When the liquid-absorbing member 3 absorbs condensate, the upper end of the liquid-absorbing member 3 can expand to fully utilize the remaining space of the receiving cavity 24 and collect more condensate. That is, by adopting a partially expandable structure and installing the liquid-absorbing member 3 at the lower end of the receiving cavity 24, the remaining space within the receiving cavity 24 can be utilized to increase the capacity for collecting and storing condensate.

[0064] In one embodiment of the atomizing device, since at least a portion of the liquid-collecting member 3 is configured to expand in volume after absorbing liquid, the liquid-collecting member 3 can expand to a larger volume to absorb more condensate, thereby increasing the condensate storage capacity and preventing condensate from entering the user's mouth or flowing back into the atomizing chamber. Furthermore, the liquid-collecting member 3 is an expandable flexible structure, allowing it to expand and deform in any space, unrestricted by the structure of the nozzle 2. This allows full utilization of the regular and irregular spaces inside the nozzle 2, increasing the liquid storage capacity of the liquid-collecting member 3, and thus avoiding the impact of condensate on the subsequent suction of some products with large mouth openings.

[0065] In one embodiment, an atomizing device is provided, the difference between this atomizing device and the atomizing device in any of the above embodiments is that the mouthpiece 2 is a transparent or semi-transparent structure.

[0066] In this embodiment, the nozzle 2 is transparent or semi-transparent. The transparent or semi-transparent nozzle 2 allows the user to see the internal structure of the nozzle 2, forming a unique appearance and making the atomizing device more recognizable.

[0067] The mouthpiece 21 and airway tube 22 of the mouthpiece 2 can be transparent or semi-transparent, or the mouthpiece 21 can be transparent or semi-transparent and the airway tube 22 can be opaque. Both can allow users to see the internal structure of the mouthpiece 2, forming a unique appearance.

[0068] After the liquid absorber 3 absorbs the condensate, the condensate will mix with e-liquid, causing the liquid absorber 3 to turn yellow. If the liquid absorber 3 is set to white, it will turn yellow after absorbing liquid. Since the mouthpiece 2 is transparent or semi-transparent, the user can see the color change of the liquid absorber 3, which will affect the appearance of the atomizing device.

[0069] In this embodiment, the liquid-absorbing component 3 is a dyed structure. For example, the liquid-absorbing component 3 is directly dyed yellow or yellowish, so that there is no color change before and after the liquid is absorbed, maintaining the consistency of the appearance of the liquid-absorbing component 3 before and after the liquid is absorbed, and ensuring the aesthetics of the atomizing device.

[0070] In one embodiment, the liquid-absorbing component 3 can also be dyed other colors, such as black, red, or other dark colors. When the liquid-absorbing component 3 absorbs the condensate, the color change of the liquid-absorbing component 3 is very small, which can also improve the aesthetics to a certain extent.

[0071] Please refer to Figure 6In one embodiment, a shielding layer 31 is provided on the outer surface of the liquid-absorbing member 3 facing the suction nozzle 2. That is, a shielding layer 31 is provided on the upper surface of the liquid-absorbing member 3. The shielding layer 31 can be a color layer printed or attached to the liquid-absorbing member 3, and the shielding layer 31 can also expand as the liquid-absorbing member 3 expands, so that after the liquid-absorbing member 3 absorbs liquid and expands, the shielding layer 31 can still cover the liquid-absorbing member 3, so that the user can only see the shielding layer 31 of the liquid-absorbing member 3 from the outside.

[0072] The shielding layer 31 can cover the color change of the liquid suction component 3 before and after liquid suction, thus ensuring the aesthetic appearance of the transparent suction nozzle 2.

[0073] Please refer to Figure 7 In one embodiment, a shielding member 32 is provided on the side of the liquid suction member 3 facing the suction nozzle 2. The shielding member 32 can be a sheet-like structure such as a plastic sheet. The shielding member 32 covers the top of the liquid suction member 3, so that the user can only see the shielding member 32 of the liquid suction member 3 from the outside. The shielding member 32 can also cover the color change of the liquid suction member 3 before and after liquid suction, and can also ensure the aesthetic appearance of the transparent suction nozzle 2.

[0074] In one embodiment, the shielding member 32 is configured to expand in volume after absorbing liquid, so that the shielding member 32 can expand along with the expansion of the liquid-absorbing member 3, ensuring that the liquid-absorbing member 3 can cover the liquid-absorbing member 3 in different forms.

[0075] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
