Description

Technical Field

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

[0002] The filling process for an atomizer generally involves two steps: first, injecting the atomizing medium into the reservoir; and second, sealing the reservoir by crimping the nozzle or other components, also known as capping. Some atomizers, due to their structural design and usage, require capping as soon as possible after filling to prevent leakage. Furthermore, most atomizers currently use batch filling, further lengthening the time interval between the filling and capping processes, thus increasing the risk of leakage. Utility Model Content

[0003] The purpose of this application is to provide an atomizer and an electronic atomizing device to solve the technical problem in the prior art where the inability to quickly cap the device after liquid injection leads to easy leakage.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: An atomizer is provided, comprising a liquid storage chamber and a sealing element. The liquid storage chamber has a storage cavity for containing an atomizing medium and an injection port communicating with the storage cavity. The sealing element includes an elastic portion and a sealing portion connected to each other. The elastic portion is installed in the liquid storage chamber. The sealing portion can block the injection port without external force. When driven by external force, the sealing portion can move to at least partially avoid the injection port. The elastic portion has a preset elastic force on the sealing portion to move the sealing portion to block the injection port.

[0005] In some embodiments, without external force, the elastic part is located outside the injection port, the sealing part is accommodated in the injection port to block the injection port, and the sealing part can be pushed into the reservoir cavity to open the injection port under external force; the elastic part has a preset elastic force on the sealing part to pull the sealing part toward the injection port.

[0006] In some embodiments, the cross-sectional area of ​​at least a portion of the injection port gradually decreases from the end of the injection port that communicates with the reservoir cavity toward the direction away from the reservoir cavity.

[0007] In some embodiments, the inner circumferential surface of the injection port includes a first guide surface and a second guide surface distributed circumferentially. The cross-sectional area of ​​the first guide surface remains constant along the axial direction and is used to guide the injection component. The cross-sectional area of ​​at least a portion of the second guide surface gradually decreases from the end of the injection port that communicates with the liquid storage cavity toward the direction away from the liquid storage cavity and is used to guide the sealing portion.

[0008] In some embodiments, the elastic portion extends from the sealing portion away from the injection port and toward the obliquely opposite side of the first guide surface.

[0009] In some embodiments, the end of the elastic part opposite to the sealing part is provided with a mounting part for connecting to the liquid storage tank, and the sealing part, the elastic part and the mounting part are integrally made of deformable material.

[0010] In some embodiments, the liquid storage chamber includes a mounting column and a limiting surface connected to the mounting column. The mounting part is sleeved on the mounting column and limited by the limiting surface, and the limiting surface is used to prevent the mounting part from continuing to slide towards the liquid storage chamber.

[0011] In some embodiments, the atomizer further includes a nozzle connected to the liquid storage chamber, the nozzle having an air outlet channel that is at least partially opposite to and communicates with the liquid inlet along the axial direction of the liquid storage chamber.

[0012] In some embodiments, the liquid storage chamber further includes a connecting cavity and a main gas channel, the main gas channel being spaced apart from the liquid storage chamber, the connecting cavity being connected to the gas outlet channel, and the connecting cavity being connected to both the main gas channel and the liquid injection port.

[0013] On the other hand, this application also provides an electronic atomizing device, including a power supply assembly and the aforementioned atomizer, wherein the power supply assembly is used to supply power to the atomizer.

[0014] The beneficial effects of the atomizer and electronic atomizing device provided in this application are as follows: By providing a sealing element in the liquid storage chamber, the sealing element includes a sealing part and an elastic part. The sealing part can block the liquid inlet without external force, and can move to at least partially avoid the liquid inlet when driven by external force. The elastic part has a preset elastic force on the sealing part to move the sealing part to block the liquid inlet. The above arrangement allows the sealing part to remain blocked by the preset elastic force of the elastic part when no other external force is applied. Even if the sealing part is pushed by an external force to open the liquid inlet, the sealing part will quickly block the liquid inlet again when the external force disappears. During liquid injection, the sealing part can be pushed by the injection element to open the liquid inlet, thereby allowing liquid to be injected into the liquid storage chamber. When the injection element is withdrawn, the sealing part will quickly block the liquid inlet again under the preset elastic force of the elastic part, reducing or even avoiding the situation where the atomizer cannot be quickly capped after liquid injection and leakage occurs.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] As described in the background section, some atomizers, due to their unique structural design and usage, require capping as soon as possible after liquid filling; otherwise, leakage is likely to occur. Furthermore, most atomizers currently use batch filling, which further lengthens the time interval between the filling and capping processes, increasing the risk of leakage.

[0030] To address the aforementioned issues, this application provides an atomizer and an electronic atomizing device. By providing a sealing element 200 in the liquid storage chamber 100, the sealing element 200 can quickly seal the liquid inlet 120 under the action of a preset elastic force when the liquid injection element 2 exits the liquid injection port 120, thereby shortening the time interval between liquid injection and capping and reducing the risk of leakage.

[0031] Please see Figures 1 to 4 The atomizer 1 provided in the embodiments of this application will now be described.

[0032] The atomizer 1 includes a liquid storage chamber 100 and a sealing element 200. The liquid storage chamber 100 has a liquid storage cavity 110 for containing atomizing medium and an injection port 120 communicating with the liquid storage cavity 110. The sealing element 200 includes an elastic part 220 and a sealing part 210. The elastic part 220 is installed in the liquid storage chamber 100, and the sealing part 210 is connected to the elastic part 220. The sealing part 210 can block the injection port 120 without external force. When the sealing part 210 is driven by external force, it can move to at least partially avoid the injection port 120. The elastic part 220 has a preset elastic force on the sealing part 210 to drive the sealing part 210 to block the injection port 120.

[0033] The sealing part 210 seals the injection port 120. This can be done by the sealing part 210 covering the outer end face of the injection port 120, covering the inner end face of the injection port 120, or being housed within the injection port 120. The outer end face of the injection port 120 refers to the end face away from the storage cavity 110, and the inner end face refers to the end face facing the storage cavity 110. When the sealing part 210 seals the injection port 120, the storage cavity 110 is sealed.

[0034] The sealing part 210 at least partially avoids the injection port 120 to open the injection port 120. This can be achieved by the sealing part 210 completely detaching from the outer end face of the injection port 120 or partially detaching from the outer end face of the injection port 120 to open the injection port 120, or by the sealing part 210 completely detaching from the inner end face of the injection port 120 or partially detaching from the outer end face of the injection port 120 to open the injection port 120, or by the sealing part 210 completely retracting from the injection port 120 or partially retracting from the injection port 120 to open the injection port 120.

[0035] It should also be noted that the elastic part 220 has a preset elastic force on the sealing part 210 to move the sealing part 210 to block the injection port 120. This means that regardless of whether the sealing part 210 is in the first state of blocking the injection port 120 or in the second state of opening the injection port 120, the elastic part 220 has a preset elastic force on the sealing part 210. This preset elastic force drives the sealing part 210 to remain in the first state or move from the second state to the first state. For example, by pushing the sealing part 210 with the injection member 2, the sealing part 210 moves to at least partially avoid the injection port 120, so that the injection port 120 is opened, and the atomizing medium can be injected into the liquid storage chamber 110 through the injection member 2. When the injection member 2 completes the injection and withdraws from the liquid storage chamber 110, the pushing force of the injection member 2 on the sealing part 210 disappears, and the sealing part 210 can return to the first state under the action of the preset elastic force of the elastic part 220 to block the injection port 120.

[0036] The atomizer 1 in this embodiment of the application provides a sealing element 200 in the liquid storage chamber 100. The sealing element 200 includes a sealing part 210 and an elastic part 220. The sealing part 210 can block the liquid inlet 120 without external force. When driven by external force, the sealing part 210 can move to at least partially avoid the liquid inlet 120. The elastic part 220 has a preset elastic force on the sealing part 210 to move the sealing part 210 to block the liquid inlet 120. The above configuration allows the sealing part 210 to keep blocking the liquid inlet 120 under the preset elastic force of the elastic part 220 without other external force. Even if the sealing part 210 is pushed by external force to open the liquid inlet 120, when the external force disappears, the sealing part 210 will quickly block the liquid inlet 120 under the preset elastic force of the elastic part 220. During liquid injection, the injection component 2 can push the sealing part 210 to open the injection port 120, allowing liquid to be injected into the storage chamber 110. When the injection component 2 is withdrawn, the sealing part 210 will quickly seal the injection port 120 under the preset elastic force of the elastic part 220, reducing or even preventing leakage due to the atomizer 1 not being able to be capped quickly after liquid injection. In addition, when liquid injection is completed, the sealing part 210 can automatically seal the injection port 120 under the drive of the elastic part 220, requiring no manpower or material resources, saving labor costs. It also allows the capping process after liquid injection to be completed in the factory or by the customer.

[0037] In some embodiments, please refer to Figures 1 to 4 In the absence of external force, the elastic part 220 is located outside the injection port 120, and the sealing part 210 can be accommodated in the injection port 120 to block the injection port 120. When driven by external force, the sealing part 210 can be pushed into the reservoir 110 to open the injection port 120. The elastic part 220 has a preset elastic force on the sealing part 210 to pull the sealing part 210 toward the injection port 120. By placing the elastic part 220 outside the injection port 120, it is easy to install the elastic part 220 in the liquid storage tank 100. Furthermore, the sealing part 210 can be pushed into the liquid storage cavity 110 to open the injection port 120. During injection, the injection component 2 is generally inserted into the liquid storage cavity 110 from the outside of the injection port 120, away from the liquid storage cavity 110. During insertion, the injection component 2 pushes the sealing part 210 into the liquid storage cavity 110 to open the injection port 120. The structure is reasonably designed and easy to operate. It is understood that in other embodiments, the elastic part 220 can also be placed inside the liquid storage cavity 110, with the elastic part 220 having a preset elastic force that pushes the sealing part 210 towards the injection port 120. For example, the elastic part 220 can be set as a compression spring.

[0038] In some embodiments, please refer to Figure 3 and Figure 4The cross-sectional area of ​​at least a portion of the injection port 120 gradually decreases from the end of the injection port 120 communicating with the reservoir 110 towards the direction away from the reservoir 110. Here, the cross-sectional area refers to the cross-sectional area of ​​the injection port 120 perpendicular to its axial direction (i.e., the depth direction of the injection port 120). This arrangement guides the sealing part 210 to move from the injection port 120 towards the reservoir 110 to open the injection port 120, and also guides the sealing part 210 to slide from the reservoir 110 into the injection port 120 to seal the injection port 120. It is understood that in other embodiments of this application, the inner diameter of the injection port 120 may also be set to remain constant along its axial direction.

[0039] In some embodiments, please refer to Figures 2 to 4 The inner circumferential surface of the injection port 120 includes a first guide surface 121 and a second guide surface 122 distributed circumferentially. The cross-sectional area of ​​the first guide surface 121 remains constant along the axial direction and is used to guide the injection component 2. At least a portion of the cross-sectional area of ​​the second guide surface 122 gradually decreases from the end of the injection port 120 that communicates with the liquid storage cavity 110 towards the direction away from the liquid storage cavity 110, and the second guide surface 122 is used to guide the sealing part 210. The cross-sectional area of ​​the first guide surface 121 refers to the cross-sectional area of ​​the first guide surface 121 perpendicular to the axial direction of the injection port 120, and the cross-sectional area of ​​the second guide surface 122 refers to the cross-sectional area of ​​the second guide surface 122 perpendicular to the axial direction of the injection port 120. With this configuration, during injection, the injection component 2 can be inserted into the liquid storage cavity 110 along the first guide surface 121 via the injection port 120, and the injection component 2 can push the sealing part 210 to slide into the liquid storage cavity 110 along the second guide surface 122. In addition, since the first guide surface 121 and the second guide surface 122 are distributed circumferentially, the liquid injection component 2 and the sealing part 210 can not interfere with each other in the liquid storage cavity 110, so that the sealing part 210 will not affect the insertion and withdrawal of the liquid injection component 2.

[0040] In some embodiments, the two opposite ends of the first guide surface 121 along the circumferential direction are connected to the two opposite ends of the second guide surface 122 along the circumferential direction. The circumferential area occupied by the first guide surface 121 and the second guide surface 122 can be designed according to the actual dimensions of the injection part 2 and the sealing part 210. Generally speaking, the circumferential area occupied by the second guide surface 122 is larger than the circumferential area occupied by the first guide surface 121. It is understood that in other embodiments of this application, the first guide surface 121 and the second guide surface 122 can also be connected by other planes, arc surfaces or curved surfaces, and this is not a unique limitation.

[0041] In some embodiments, please refer to Figures 2 to 4The sealing part 210 is spherical, and the cross-section of the injection port 120 is circular, with the cross-sectional area of ​​the injection port varying along the axial direction. The cross-section of the injection port 120 refers to the section perpendicular to its axial direction. The outer diameter of the sealing part 210 is larger than the minimum inner diameter of the injection port 120, meaning the outer diameter of the sealing part 210 is larger than the inner diameter of the portion of the injection port 120 that mates with the sealing part 210. This ensures an interference fit between the sealing part 210 and the injection port 120, achieving a better sealing effect. Understandably, in other embodiments of this application, the sealing part 210 may also be frustum-shaped, cylindrical, or its cross-section may be elliptical or other shapes formed by multiple concentric curves.

[0042] In some embodiments, please refer to Figures 2 to 4 The elastic portion 220 extends from the sealing portion 210 away from the injection port 120 and toward the obliquely opposite side of the first guide surface 121. Here, the obliquely opposite side of the first guide surface 121 refers to a position located opposite the first guide surface 121 and offset from the first guide surface 121 along the axial direction of the injection port 120. In general, the elastic portion 220 extends obliquely away from the first guide surface 121, allowing it to avoid the insertion action of the injection component 2 and ensuring smooth injection.

[0043] In some embodiments, when the sealing part 210 is in the blocking state of the injection port 120, the axial orthogonal projection of the elastic part 220 along the liquid storage cavity 110 is outside the axial orthogonal projection of the first guide surface 121 along the liquid storage cavity 110. That is, the projections of the elastic part 220 and the first guide surface 121 do not intersect. When the injection component 2 is inserted into the first guide surface 121 along the axial direction of the liquid storage cavity 110, the elastic part 220 will not cause structural interference to the insertion of the injection component 2.

[0044] In some embodiments, please refer to Figures 2 to 5 The elastic part 220 has a mounting part 230 for connecting to the liquid storage tank 100 at one end opposite to the sealing part 210. The sealing part 210, the elastic part 220, and the mounting part 230 are integrally made of soft rubber material. This configuration not only simplifies the manufacturing of the sealing element 200 and reduces its cost, but also ensures that the sealing part 210 is elastic enough to elastically abut against the inner circumferential surface of the injection port 120 to seal the injection port 120. Simultaneously, the elastic part 220 is elastic enough to exert an elastic pulling force on the sealing part 210. It is understood that in other embodiments of this application, the sealing part 210 can also be made of soft rubber material, and then an elastic element, such as a spring or elastic rope, can be connected between the mounting part 230 and the sealing part 210; this is not a unique limitation.

[0045] In some embodiments, please refer to Figures 2 to 4The elastic portion 220 is elongated. In the first state, the elastic portion 220 is inclined relative to the axial direction of the injection port 120, and the elastic portion 220 is located on the side opposite to the first guide surface 121, that is, the elastic portion 220 can avoid the injection component 2. In the second state, the sealing portion 210 is housed in the reservoir cavity 110, and the elastic portion 220 is close to a linearly stretched state along the axial direction, so as to exert an upward pulling force on the sealing portion 210. In addition, the inner diameter of the reservoir cavity 110 can be set large enough so that the sealing portion 210 will not exert a squeezing force on the injection component 2 in the reservoir cavity 110 when it is in the second state.

[0046] In some embodiments, please refer to Figures 2 to 4 and Figure 6 The liquid storage chamber 100 includes a mounting post 160 and a limiting surface 171 connected to the mounting post 160. The mounting part 230 is sleeved on the mounting post 160 and limited by the limiting surface 171, which prevents the mounting part 230 from sliding further towards the liquid storage cavity 110. During installation, simply sleeve the mounting part 230 on the mounting post 160 and slide it along the mounting part 230 to the limiting surface 171. The limiting surface 171 restricts the mounting part 230 from sliding further towards the liquid storage cavity 110, thereby ensuring that when the sealing part 210 is pushed into the liquid storage cavity 110, the elastic part 220 exerts a preset pulling force on the sealing part 210 towards the injection port 120. Furthermore, the above configuration simplifies the assembly of the sealing member 200. It is understood that in other embodiments of this application, the mounting part 230 can also be fixed by screw locking, bonding, or snap-fitting, etc., and this is not a unique limitation.

[0047] Optionally, the mounting part 230 is annular, the mounting post 160 extends axially along the liquid storage cavity 110, and the mounting part 230 is sleeved on the mounting part 230 axially.

[0048] In some embodiments, please refer to Figures 1 to 4 The atomizer 1 also includes a nozzle 300 connected to the liquid storage chamber 100. The nozzle 300 has an air outlet channel 310, which is at least partially aligned with and communicates with the liquid inlet 120 along the axial direction of the liquid storage chamber 110. With this configuration, during liquid injection, the injection component 2 can be directly inserted into the liquid inlet 120 via the air outlet channel 310 of the nozzle 300 and then inserted into the liquid storage chamber 110 from the liquid inlet 120 to meet the injection conditions. After injection, the injection component 2 is withdrawn via the air outlet channel 310 of the nozzle 300, and the sealing part 210 seals the liquid inlet 120 under the preset elastic force of the elastic part 220. The nozzle 300 does not need to be disassembled before injection, and it does not need to be capped or reinstalled after injection. Operation is simple; injection can be completed in the factory or by the customer, greatly improving the convenience of injection and reducing labor costs.

[0049] In some embodiments, the liquid storage tank 100 further includes a connecting cavity 140 and a main gas channel 130. The main gas channel 130 is spaced apart from the liquid storage tank 110, and the connecting cavity 140 is connected to the gas outlet channel 310. The connecting cavity 140 is also connected to both the main gas channel 130 and the injection port 120. The connecting cavity 140 not only connects the injection port 120 to the gas outlet channel 310, allowing the injection component 2 to be inserted into the liquid storage tank 110 sequentially via the gas outlet channel 310, the connecting cavity 140, and the injection port 120 for injection, but also connects the main gas channel 130 to the gas outlet channel 310, allowing aerosols in the main gas channel 130 to be discharged via the gas outlet channel 310. The overall structure is simple. It is understood that in other embodiments of this application, the connecting cavity 140 may be omitted, and the main gas channel 130 and the injection port 120 may be connected to the gas outlet channel 310 via two different channels; this is not a limiting factor.

[0050] Optionally, please refer to Figures 2 to 4 and Figure 6 The mounting post 160 protrudes from the inner circumferential surface of the connecting cavity 140, and a through groove 170 is formed on the peripheral sidewall of the connecting cavity 140 corresponding to the position of the mounting post 160. The limiting surface 171 is formed by the bottom sidewall of the through groove 170. It can be understood that in other embodiments, the mounting post 160 may also be directly formed on the bottom sidewall of the connecting cavity 140, which is not the only limitation here.

[0051] In some embodiments, please refer to Figure 7 The liquid storage chamber 100 also has an atomizing chamber 150, which is located on the side of the liquid storage chamber 110 away from the connecting chamber 140. The liquid storage chamber 100 also contains a heating element 400, with its inlet surface 410 connected to the liquid storage chamber 110 and its atomizing surface 420 communicating with the atomizing chamber 150. A main gas channel 130 connects the atomizing chamber 150 and the connecting chamber 140. The atomizing medium in the liquid storage chamber 110 enters the heating element 400 through its inlet surface 410. When the heating element 400 is energized, it heats and atomizes the atomizing medium to form an aerosol on the atomizing surface 420. The gas in the atomizing chamber 150 carries the aerosol to the main gas channel 130 and out through the connecting chamber 140 and the outlet channel 310.

[0052] In some embodiments, please refer to Figure 1 The main air passage 130 and the liquid storage chamber 110 both extend along the axial direction of the atomizer 1 and are spaced laterally along the atomizer 1. The axial direction of the atomizer 1 refers to the axial direction extending from one end of the atomizer 1 to the other end, which is also the height direction when the atomizer 1 is placed vertically. The lateral direction of the atomizer 1 refers to the direction perpendicular to the axial direction of the atomizer 1.

[0053] In some embodiments, please refer to Figure 7 The liquid inlet surface 410 of the heating element 400 is perpendicular to the axis of the atomizer 1, and the atomizing surface 420 of the heating element 400 is perpendicular to the axis of the atomizer 1. A heating base 500 and a sealing sleeve 600 are installed at the end of the liquid storage chamber 110 away from the connecting chamber 140. The sealing sleeve 600 is fitted onto the heating element 400, and the outer peripheral wall of the sealing sleeve 600 elastically abuts against the inner peripheral wall of the liquid storage chamber 110. The heating base 500 and the sealing sleeve 600 are inserted and fitted together, thereby forming a seal between the liquid storage chamber 110 and the atomizing chamber 150.

[0054] In some embodiments, please refer to Figure 7 The atomizer 1 also includes a first electrode 700, a second electrode 800, an electrode support 900, and a connector 1000. The connector 1000 is connected to the end of the liquid storage chamber 100 away from the mouthpiece 300 and is used to connect to a power supply assembly. The electrode support 900 is mounted on the connector 1000, and the first electrode 700 and the second electrode 800 are respectively mounted on the electrode support 900.
