Description

Technical Field

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

[0002] Atomizing devices utilize the atomizing components of an atomizer to atomize an aerosol-generating matrix into an aerosol, which can then be expelled from the nozzle on the atomizing chamber. To prevent aerosol leakage, a sealing structure is typically installed between the atomizing components and the nozzle.

[0003] In related technologies, the inner circumference of the sealing ring in the sealing structure can form a vent hole for aerosol to pass through. The inner circumference of the sealing ring is not supported, and the sealing ring is prone to deforming inward. After deformation, a gap will be formed on the sealing surface of the outer circumference of the sealing ring, resulting in a deterioration of the sealing effect of the sealing structure. Utility Model Content

[0004] The purpose of this application is to provide an atomizer and atomizing device to solve the technical problem of poor sealing effect.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, an atomizer is provided, comprising a mouthpiece, a liquid storage chamber, an atomizing component, and a sealing component. The mouthpiece is disposed on the liquid storage chamber, and the atomizing component is disposed within the liquid storage chamber. The sealing component comprises a support frame and a first sealing ring. The support frame is disposed within and connected to the liquid storage chamber. The support frame has a through hole that communicates with the mouthpiece. The support frame has a first receiving groove along the axial direction of the through hole and on the side away from the mouthpiece. The first sealing ring is disposed within the first receiving groove and surrounds the through hole. The inner and outer circumferential surfaces of the first sealing ring abut against the groove wall of the first receiving groove.

[0007] Through the above technical solution, the support frame is provided with a through hole, which connects to the nozzle of the atomizer. The atomizer atomizes the aerosol generating matrix to form an aerosol that can enter the nozzle through the through hole and then be discharged from the nozzle. The first sealing ring is set in the first receiving groove, which surrounds the through hole. The groove wall of the first receiving groove can support the outer and inner circumferential surfaces of the first sealing ring, thereby preventing the first sealing ring from deforming radially and thus improving the sealing effect.

[0008] In addition, the sealing assembly is independent of components such as the liquid storage tank and atomizing assembly, and can be installed as a whole, which facilitates the assembly of the atomizer and helps to reduce costs.

[0009] Therefore, the atomizer provided in this application can solve the technical problem of poor sealing effect and also helps to reduce costs.

[0010] In some embodiments, the first receiving groove includes a first sidewall and a second sidewall, the first sidewall being disposed around the through hole, the second sidewall being disposed around the first sidewall, the first sidewall abutting against the inner peripheral surface of the first sealing ring, and the second sidewall abutting against the outer peripheral surface of the first sealing ring.

[0011] In this way, the first receiving groove can abut against the inner circumferential surface of the first sealing ring using the first sidewall and against the outer circumferential surface of the first sealing ring using the second sidewall, thereby preventing the first sealing ring from deforming radially and thus improving the sealing effect.

[0012] In some embodiments, the end face of the first sidewall away from the bottom wall of the first receiving groove is called the first end face, and the end face of the second sidewall away from the bottom wall of the first receiving groove is called the second end face. The distance between the first end face and the bottom wall of the first receiving groove is greater than the distance between the second end face and the bottom wall of the first receiving groove.

[0013] In this way, the first sidewall can increase the contact area with the inner circumferential surface of the first sealing ring, thereby improving the sealing effect.

[0014] In some embodiments, the first sealing ring includes a first sealing portion and a second sealing portion, the second sealing portion being disposed on the side of the first sealing portion away from the bottom wall surface of the first receiving groove, and the radial dimension of the outer peripheral surface of the second sealing portion being smaller than the radial dimension of the outer peripheral surface of the first sealing portion, and at least a portion of the second sealing portion extending into the atomizing tube of the atomizing assembly.

[0015] In this way, the second sealing part can extend into the atomizing tube of the atomizing assembly, and the side surface of the first sealing part facing the second sealing part can fit against the end face of the atomizing tube facing the bottom wall of the first receiving groove, thereby improving the sealing effect.

[0016] In some embodiments, the inner and / or outer circumferential surfaces of the first sealing ring are provided with a first annular protrusion.

[0017] In this way, the first sealing ring can enhance the sealing effect through the first annular protrusion.

[0018] In some embodiments, a limiting protrusion is provided on the side of the first sealing ring away from the bottom wall of the first receiving groove, and the limiting protrusion is used to abut against the oil storage cotton of the atomizing component.

[0019] In this way, the first sealing ring, by abutting against the oil-retaining cotton of the atomizing component, restricts the axial displacement of the oil-retaining cotton in the through hole. Furthermore, the oil-retaining cotton can also, to at least some extent, prevent the first sealing ring from deforming axially in the through hole, thus improving the sealing effect.

[0020] In some embodiments, the support frame is provided with a second receiving groove on the other side along the axial direction of the through hole, the through hole penetrates the bottom wall of the second receiving groove, and the sealing assembly further includes absorbent cotton and a second sealing ring. The absorbent cotton is disposed in the second receiving groove and the absorbent cotton protrudes from the through hole; the second sealing ring covers at least a portion of the absorbent cotton and the second sealing ring protrudes from the through hole, the second sealing ring is connected to the outer peripheral side of the support frame, and seals the connection between the liquid storage tank and the suction nozzle.

[0021] In this way, the second sealing ring can cover the absorbent cotton, making it easy to hide the absorbent cotton, and the outer periphery of the support frame can be connected to the liquid storage tank through the second sealing ring, thereby sealing the connection between the support frame and the liquid storage tank.

[0022] In some embodiments, the second sealing ring includes a third sealing portion and a fourth sealing portion, the third sealing portion covering at least a portion of the absorbent cotton, and the fourth sealing portion connected to the third sealing portion and connected to the outer peripheral side of the support frame.

[0023] In this way, the second sealing ring can cover the absorbent cotton using the third sealing part, making it easy to hide the absorbent cotton. Furthermore, the outer periphery of the support frame can be connected to the liquid storage chamber via the fourth sealing part, thus sealing the connection between the support frame and the liquid storage chamber. This also allows the first sealing ring to be easily installed and removed along with the support frame, facilitating replacement and maintenance from the outside of the atomizer. In addition, the fourth sealing part connects to the third sealing part, making the third and fourth sealing parts of the first sealing ring a single component, further simplifying installation and removal.

[0024] In some embodiments, the inner and / or outer peripheral surfaces of the fourth sealing portion are provided with a second annular protrusion.

[0025] In this way, the fourth sealing part can improve the sealing effect through the second annular protrusion.

[0026] Secondly, this application provides an atomizing device, which includes the atomizer of any of the above embodiments. The atomizing device provided by this application has the same or similar technical effects as the atomizer of any of the above embodiments, and will not be described again here.

[0042] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0043] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0044] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0045] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0046] Please refer to the following: Figure 1 and Figure 2 The atomizing device 100 can atomize the aerosol generating matrix into aerosol using the atomizing component of the atomizer, and the aerosol can be discharged from the nozzle 11 on the liquid storage tank 10. To prevent aerosol leakage, a sealing structure is usually provided between the atomizing component and the nozzle.

[0047] In related technologies, the inner circumferential side of the sealing ring 10-1 of the sealing structure can form a vent hole 10-2 for aerosol to pass through. The inner circumferential side of the sealing ring 10-1 is not supported, and the sealing ring 10-1 is prone to deforming inward. After deformation, a gap will be formed on the sealing surface of the outer circumferential side of the sealing ring 10-1, resulting in a deterioration of the sealing effect of the sealing structure.

[0048] To address the aforementioned technical problems, embodiments of this application provide an atomizer and an atomizing device.

[0049] Please refer to the following: Figure 3 and Figure 4The atomizing device 100 provided in this application embodiment includes a housing 20, an atomizer, a bottom shell 50, and a battery 40. The atomizer can be installed inside the housing 20 and one end of the housing 20 is sealed. The atomizer is used to atomize the aerosol generation matrix. The bottom shell 50 is connected to the other end of the housing 20 to seal the other end of the housing 20. The battery 40 can be located in the battery 40 compartment between the atomizer and the bottom shell 50. The battery 40 can power the atomizer.

[0050] Please refer to the following: Figure 4 and Figure 5 The atomizer provided in this embodiment includes a liquid storage chamber 10, which is connected to one end of the outer shell 20. The liquid storage chamber 10 has a liquid storage cavity 101, which can store the aerosol generation matrix. The atomizer also includes an atomizing component 30, which includes an atomizing tube 31 and an oil-retaining cotton 32 disposed in the atomizing tube 31. The aerosol generation matrix in the liquid storage chamber 10 can enter the oil-retaining cotton 32 through the micropores in the atomizing tube 31 for temporary storage. The atomizing component 30 also includes a heating element (not shown in the figure), which can heat and atomize the aerosol generation matrix absorbed by the oil-retaining cotton 32 to form an aerosol.

[0051] Optionally, the atomizer provided in this embodiment includes a nozzle 11, which is disposed on the liquid storage chamber 10. For example, the nozzle 11 is integrally connected to the liquid storage chamber 10, or the nozzle 11 can be fixedly connected to the liquid storage chamber 10. The liquid storage chamber 10 is provided with an mounting flange 12 extending into the interior of the liquid storage cavity 101 away from the nozzle 11. The aerosol generated by the atomization of the aerosol generating matrix through the heating and atomization of the atomization assembly 30 can be discharged outward through the exhaust channel 1101 of the nozzle 11.

[0052] Optionally, the nozzle 11 is provided with an exhaust pipe 111 extending into the atomizing chamber, the exhaust pipe 111 forming the exhaust channel 1101, the nozzle 11 is also provided with a nozzle cavity 1102, at least a portion of the exhaust pipe 111 is located in the nozzle cavity 1102, and the nozzle 11 can be made into a transparent thin shell, which can improve the appearance.

[0053] To prevent leakage of aerosol during the process of being delivered to the exhaust channel 1101 after being heated and atomized by the atomizing component 30, the atomizer provided in this application embodiment includes a sealing component 60. The sealing component 60 can connect the mounting flange 12 and the exhaust pipe 111, and can block the opening of the mouthpiece cavity 1102 facing the atomizing cavity, thereby preventing aerosol from leaking into the mouthpiece cavity 1102.

[0054] Please refer to the following: Figure 5 and Figure 6The sealing assembly 60 provided in this application includes a support frame 61, which is disposed within and connected to the liquid storage chamber 10 of the atomizer. The support frame 61 can be sealed to the mounting flange 12 and to the exhaust pipe 111, thereby preventing aerosol leakage into the mouthpiece cavity 1102.

[0055] The support frame 61 is provided with a through hole 6101, which connects to the nozzle 11 of the liquid storage tank 10. The aerosol generated by the atomizer can enter the exhaust channel 1101 of the nozzle 11 through the through hole 6101 and then be discharged from the nozzle 11.

[0056] Optionally, the sealing assembly 60 provided in this application further includes a first sealing ring 62. A first receiving groove 6102 is provided on the side of the support frame 61 along the axial direction of the through hole 6101 (as shown in the Z direction) and away from the nozzle 11. The first sealing ring 62 is disposed within the first receiving groove 6102 and surrounds the through hole 6101. The first sealing ring 62 is disposed within the liquid storage chamber 10 and connected to the atomizing assembly 30 of the atomizer. The inner and outer circumferential surfaces of the first sealing ring 62 abut against the groove wall of the first receiving groove 6102. In this way, the groove wall of the first receiving groove 6102 can support the outer and inner circumferential surfaces of the first sealing ring 62, thereby preventing radial deformation of the first sealing ring 62 and improving the sealing effect.

[0057] Optionally, the first sealing ring 62 can be installed in the first receiving groove 6102 by interference fit, or it can be bonded to the groove wall of the first receiving groove 6102.

[0058] In addition, the sealing component 60 can be installed independently of components such as the liquid storage chamber 10 and the atomizing component 30, which facilitates the assembly of the atomizer and helps to reduce costs.

[0059] Therefore, the atomizer provided in this application embodiment can solve the technical problem of poor sealing effect and also helps to reduce costs.

[0060] Please see Figure 7 In some embodiments, the first receiving groove 6102 includes a first sidewall 61-1 and a second sidewall 61-2. The first sidewall 61-1 is disposed around the through hole 6101, and the second sidewall 61-2 is disposed around the first sidewall 61-1. The first sidewall 61-1 abuts against the inner circumferential surface of the first sealing ring 62, and the second sidewall 61-2 abuts against the outer circumferential surface of the first sealing ring 62. That is, the first receiving groove 6102 is an annular groove, and at least a portion of the first sealing ring 62 can be embedded in the first receiving groove 6102. This can prevent the first sealing ring 62 from deforming radially, thereby improving the sealing effect.

[0061] In some embodiments, the end face of the first sidewall 61-1 away from the bottom wall surface (first bottom wall surface 61-3) of the first receiving groove 6102 is the first end face, and the end face of the second sidewall 61-2 away from the bottom wall surface of the first receiving groove 6102 is the second end face. The distance between the first end face and the bottom wall surface of the first receiving groove 6102 is greater than the distance between the second end face and the bottom wall surface of the first receiving groove 6102. That is, the dimension of the first sidewall 61-1 in the axial direction of the through hole 6101 is greater than the dimension of the second sidewall 61-2 in the axial direction of the through hole 6101.

[0062] In this way, the first sidewall 61-1 can increase the contact area with the inner circumferential surface of the first sealing ring 62, extend the sealing path, and thus help improve the sealing effect.

[0063] Please refer to the following: Figure 5 , Figure 6 and Figure 7 Optionally, the first sealing ring 62 includes a first sealing portion 621 and a second sealing portion 622. The second sealing portion 622 is disposed on the side of the first sealing portion 621 away from the bottom wall surface of the first receiving groove 6102, and the radial dimension of the outer peripheral surface of the second sealing portion 622 is smaller than the radial dimension of the outer peripheral surface of the first sealing portion 621. At least a portion of the second sealing portion 622 extends into the atomizing tube 31 of the atomizing assembly 30, so that the first sealing ring 62 is sealed to the atomizing assembly 30. In this way, a contact surface 623 can be formed on the side surface of the first sealing portion 621 facing the second sealing portion 622. The contact surface 623 is disposed around the second sealing portion 622, and the contact surface 623 is in contact with the end face of the atomizing tube 31 facing the bottom wall surface of the first receiving groove 6102. This can seal the end face of the atomizing tube 31 facing the bottom wall surface of the first receiving groove 6102, thereby increasing the sealing position of the atomizing tube 31 and thus improving the sealing effect.

[0064] Please continue reading. Figure 7 In some embodiments, the inner and / or outer circumferential surfaces of the first sealing ring 62 are provided with a first annular protrusion 6202, and the sealing ring 10-1 can increase the sealing effect through the first annular protrusion 6202.

[0065] For example, the inner circumferential surface of the first sealing ring 62 is provided with a first annular protrusion 6202. For example, the outer circumferential surface of the first sealing ring 62 is provided with a first annular protrusion 6202. For example, both the inner and outer circumferential surfaces of the first sealing ring 62 are provided with the first annular protrusion 6202.

[0066] The outer peripheral surface of the first sealing ring 62 includes a portion disposed on the first sealing part 621 and a portion disposed on the second sealing part 622. The portion of the outer peripheral surface of the first sealing ring 62 disposed on the first sealing part 621 can be the first sealing surface, and the portion of the outer peripheral surface of the first sealing ring 62 disposed on the second sealing part 622 can be the second sealing surface. When the outer peripheral surface of the first sealing ring 62 is provided with a first annular protrusion 6202, the first annular protrusion 6202 can be disposed on either the first sealing surface or the second sealing surface. Of course, the first annular protrusion 6202 can also be disposed on both the first sealing surface and the second sealing surface simultaneously.

[0067] Please refer to the following: Figure 5 , Figure 6 and Figure 7 In some embodiments, a limiting protrusion 6201 is provided on the side of the first sealing ring 62 away from the bottom wall of the first receiving groove 6102, and the limiting protrusion 6201 abuts against the oil storage cotton 32 of the atomizing component 30.

[0068] In this way, the first sealing ring 62, by abutting against the oil-retaining cotton 32 of the atomizing component 30, restricts the axial displacement of the oil-retaining cotton 32 in the through hole 6101. In addition, the oil-retaining cotton 32 can also at least partially prevent the first sealing ring 62 from deforming axially in the through hole 6101, which is beneficial to improving the sealing effect.

[0069] Optionally, there can be multiple limiting protrusions 6201, which are arranged around the through hole 6101. This allows the limiting protrusions 6201 to abut against the oil-retaining cotton 32 of the atomizing component 30 at multiple locations, improving the stability of the oil-retaining cotton 32. Furthermore, multiple limiting protrusions 6201 can improve the uniformity of force on the first sealing ring 62, helping to prevent deformation of the first sealing ring 62 and thus improving the sealing effect.

[0070] Optionally, the limiting protrusion 6201 can be annular. The annular limiting protrusion 6201 is arranged around the through hole 6101, and the limiting protrusion 6201 can seal the end face of the oil storage cotton 32 facing the support frame 61.

[0071] Please continue reading. Figure 5 and Figure 7 In some embodiments, the support frame 61 is provided with a second receiving groove 61-3 on the other side of the through hole 6101. The through hole 6101 penetrates the bottom wall surface (second bottom wall surface 61-4) of the second receiving groove 61-3. The sealing assembly 60 also includes absorbent cotton 63 and a second sealing ring 64. The absorbent cotton 63 is disposed in the second receiving groove 61-3 and the absorbent cotton 63 protrudes from the through hole 6101.

[0072] The absorbent cotton 63 is provided with a first connecting hole 6301, which can expose the through hole 6101 and is connected to the through hole 6101, so that aerosol can enter the first connecting hole 6301 through the through hole 6101.

[0073] Optionally, the absorbent cotton 63 can be connected to the second receiving tank 61-3 by an interference fit, or it can be bonded to the tank wall of the second receiving tank 61-3.

[0074] Optionally, the first connecting hole 6301 is connected to the exhaust channel 1101, so that the aerosol enters the exhaust channel 1101 through the first connecting hole 6301.

[0075] For example, the diameter of the first connecting hole 6301 is equal to the diameter of the through hole 6101, which facilitates the mating of the first connecting hole 6301 and the through hole 6101 and makes it easier to process the first connecting hole 6301 and the through hole 6101.

[0076] Optionally, the second sealing ring 64 covers at least a portion of the absorbent cotton 63, and the second sealing ring 64 is exposed above the through hole 6101. The second sealing ring 64 has a second connecting hole 6401, which is exposed above the through hole 6101, and the second connecting hole 6401 communicates with the through hole 6101 through a first connecting hole 6301.

[0077] The diameter of the second connecting hole 6401 can be equal to the diameter of the through hole 6101, or the diameter of the second connecting hole 6401 can be larger than the diameter of the through hole 6101.

[0078] Optionally, when the diameter of the second connecting hole 6401 is equal to the diameter of the through hole 6101, the second sealing ring 64 can completely cover the absorbent cotton 63, and the second sealing ring 64 can abut against the exhaust pipe 111 and the absorbent cotton 63 to achieve a sealing connection with the exhaust pipe 111, thereby achieving a sealing effect.

[0079] Optionally, when the diameter of the second connecting hole 6401 is larger than the diameter of the through hole 6101, the second sealing ring 64 can cover part of the absorbent cotton 63, so that the part of the absorbent cotton 63 near the inner side of the first connecting hole 6301 is exposed. At this time, the second sealing ring 64 can be sealed to the outer peripheral surface of the exhaust pipe 111, thereby achieving a sealing effect. That is, the support frame 61 can be sealed to the exhaust pipe 111 through the second sealing ring 64.

[0080] It is understandable that the exposed part of the absorbent cotton 63 can come into contact with the exhaust pipe 111, thereby using the exhaust pipe 111 to cover the exposed part of the absorbent cotton 63.

[0081] It should be noted that the moisture contained in the aerosol can condense in the exhaust channel 1101 to form condensate. After the condensate flows back, it can be absorbed by the absorbent cotton 63. After absorbing the condensate, the absorbent cotton 63 is prone to discoloration, for example, turning yellow. This affects the aesthetics when seen through the transparent nozzle 11. Therefore, the sealing component 60 provided in this application embodiment can cover the absorbent cotton 63, thus hiding the absorbent cotton 63 and improving the aesthetics of the atomizing device 100.

[0082] Optionally, the second sealing ring 64 is connected to the outer periphery of the support frame 61, and the second sealing ring 64 is sealed to the mounting flange 12 of the liquid storage tank 10. Therefore, the outer periphery of the support frame 61 can be connected to the liquid storage tank 10 through the second sealing ring 64, thereby sealing the connection between the support frame 61 and the liquid storage tank 10.

[0083] Please see Figure 6 and Figure 7 In some embodiments, the second sealing ring 64 includes a third sealing portion 641 and a fourth sealing portion 642. The third sealing portion 641 covers at least a portion of the absorbent cotton 63, and the fourth sealing portion 642 is connected to the third sealing portion 641 and to the outer peripheral side of the support frame 61.

[0084] Optionally, the third sealing part 641 and the fourth sealing part 642 can be integrally formed, or they can be bonded together.

[0085] In this way, the second sealing ring 64 can cover the absorbent cotton 63 with the third sealing part 641, making it easy to hide the absorbent cotton 63. Furthermore, the outer periphery of the support frame 61 can be connected to the liquid storage chamber 10 through the fourth sealing part 642, thereby sealing the connection between the support frame 61 and the liquid storage chamber 10. It also allows the first sealing ring 62 to be disassembled and installed along with the support frame 61, making it easy to replace and maintain it from the outside of the atomizer.

[0086] In addition, the fourth sealing part 642 is connected to the third sealing part 641, so that the third sealing part 641 and the fourth sealing part 642 of the first sealing ring 62 can be connected as a single component, which facilitates disassembly and assembly.

[0087] Optionally, the inner and / or outer peripheral surfaces of the fourth sealing portion 642 are provided with a second annular protrusion 6421, which can improve the sealing effect of the fourth sealing portion 642. Specifically, the second annular protrusion 6421 is provided on the inner peripheral surface of the fourth sealing portion 642, or the second annular protrusion 6421 is provided on both the inner and outer peripheral surfaces of the fourth sealing portion 642.

[0088] Optionally, the second connecting hole 6401 is provided in the third sealing part 641, and the hole wall of the second connecting hole 6401 may be provided with a third annular protrusion 6411, which can improve the sealing effect between the third sealing part 641 and the exhaust pipe 111.

[0089] The above are merely specific embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
