Description

Technical Field

[0001] This utility model relates to the field of electronic atomization equipment technology, and in particular to a self-sealing liquid reservoir and electronic atomizer. Background Technology

[0002] Traditional electronic atomizers consist of an atomizing component and a power supply component. The atomizing component includes components such as a liquid reservoir and an atomizing core. The liquid reservoir provides the atomizing matrix required for the atomizing core to generate aerosol. When the atomizing core is powered on, the atomizing matrix is ​​heated to generate aerosol. The power supply component provides the electrical energy required for the atomizing core to generate heat.

[0003] Existing electronic atomizers have a reservoir that provides additional atomizing matrix to the reservoir chamber. The reservoir can be separated from and combined with the electronic atomizer. When the existing reservoir is combined with the electronic atomizer, the seal at the reservoir outlet is broken, and the atomizing matrix in the reservoir can be transferred into the reservoir chamber. When the reservoir is separated from the electronic atomizer, the outlet cannot be sealed in time, and some atomizing matrix will overflow from the reservoir outlet. Utility Model Content

[0004] The main purpose of this invention is to propose a self-sealing liquid reservoir, which can solve the problem in the prior art that the liquid reservoir cannot seal itself after being separated from the electronic atomizer.

[0005] To achieve the above objectives, this application provides a self-sealing liquid reservoir, which includes:

[0006] The outer shell has an internally defined liquid supply chamber for storing liquid, and the outer shell has a liquid outlet that communicates with the liquid supply chamber.

[0007] A first sealing element is disposed in the liquid supply chamber. The first sealing element has a first state of closing the liquid outlet and a second state of being driven by an external force to open the liquid outlet. The first sealing element automatically closes the liquid outlet when the external force disappears and returns to the first state.

[0008] In some embodiments, the housing includes a shell and a cover, the shell and the cover together defining the liquid supply chamber, and the liquid outlet is disposed on the cover or the shell.

[0009] In some embodiments, the first seal includes a proximal end and a distal end, the proximal end being connected to the housing, and the distal end being configured to close the free end of the outlet under force support.

[0010] In some embodiments, the first seal is made of plastic material, the proximal end is sheet-shaped and snaps into the liquid supply chamber, and the distal end is configured as a free end and closes the liquid outlet under its own elastic support.

[0011] In some embodiments, an elastic support is provided between the opposing surfaces of the proximal end and the distal end, the elastic support providing a force to the distal end to close the outlet.

[0012] In some embodiments, the first seal includes a movable member and an elastic member, the elastic member being disposed within the liquid supply chamber and connected to the housing, and providing the movable member with a force to close the liquid outlet.

[0013] In some embodiments, the elastic element described above is a sheet or a torsion spring.

[0014] In some embodiments, the reservoir further includes a second seal that is detachably or removably mounted on the outer wall of the housing to seal the outlet.

[0015] In some embodiments, this application provides an electronic atomizer, the electronic atomizer including an atomizing component and the aforementioned liquid reservoir, the atomizing component having a liquid reservoir chamber, the liquid reservoir being detachably connected to the atomizing component, the liquid reservoir comprising:

[0016] The outer shell has an internally defined liquid supply chamber for storing liquid, and the outer shell has a liquid outlet that communicates with the liquid supply chamber.

[0017] A first sealing element is disposed within the liquid supply chamber. The first sealing element has a first state of automatically closing the liquid outlet and a second state of being driven by an external force to open the liquid outlet.

[0018] In the first state, when the liquid reservoir is not supplied with liquid or after the liquid reservoir is separated from the atomizing component, the first seal closes the liquid outlet under its own elasticity or external force.

[0019] In the second state, after the liquid reservoir is connected to the atomizing assembly, the atomizing assembly pushes the first seal to open the liquid outlet and connect the liquid reservoir and the liquid supply chamber.

[0020] In some embodiments, the atomizing assembly is provided with a liquid inlet pipe, one end of which is connected to the liquid storage chamber, and the other end of which is exposed on the surface of the atomizing assembly;

[0021] After the liquid reservoir is connected to the atomizing assembly, the inlet pipe pushes the first seal to open the outlet and connect the liquid reservoir and the supply chamber.

[0022] Compared with the prior art, this utility model has obvious advantages and beneficial effects. After the liquid reservoir and the atomizing component are connected and combined, the atomizing component applies pressure to the first seal, breaking the sealing state of the first seal on the liquid outlet of the liquid reservoir, so that the atomized matrix stored in the liquid reservoir can be injected into the liquid storage chamber of the atomizing component. After the liquid reservoir and the atomizing component are separated, the pressure applied by the atomizing component to the first seal gradually disappears, and the first seal re-closes the liquid outlet under its own elasticity or the support of other components.

[0037] To make the above-mentioned objects, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] In the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0039] Electronic atomizers can be used in various fields, such as medical atomization, beauty atomization, and cigarette replacement. They primarily work by heating an atomization substrate to generate an aerosol, which can be a liquid substrate containing or without nicotine. Electronic atomizers generally consist of an atomization component and a power supply component. The atomization component includes a reservoir that stores the atomization substrate and an atomizer core. The reservoir stores the atomization substrate, and the atomizer core heats and atomizes the substrate to generate an aerosol. The power supply component provides power to the atomizer core.

[0040] Electronic atomizers have small reservoirs that cannot sustain aerosol production for extended periods, requiring users to inject atomizing matrix into the reservoir via an external container. Existing electronic atomizers include reservoirs that provide additional atomizing matrix to the reservoir. These reservoirs can be detached from the atomizer; however, when detached, some atomizing matrix leaks from the reservoir's outlet.

[0041] This application provides a self-sealing liquid reservoir, such as... Figure 1-9As shown, the liquid reservoir 1 includes a housing and a first sealing member 13. The housing defines a liquid supply chamber 11 for storing liquid. The housing is provided with a liquid outlet 12, which communicates with the liquid supply chamber 11. The first sealing member 13 is disposed in the liquid supply chamber 11 and has a first state of closing the liquid outlet 12 and a second state of opening the liquid outlet 12.

[0042] like Figure 1 As shown, in the first state, the first seal 13 can seal the liquid outlet 12 under its own elasticity or the support of external force.

[0043] like Figure 4 or Figure 9 As shown, in the second state, the first seal 13 is driven by an external force to open the liquid outlet 12.

[0044] like Figure 3 As shown, the outer casing includes a housing 10 and a cover 15. An opening 14 is provided on one side of the housing 10, and the cover 15 is fixed to the opening 14. The housing 10 and the cover 15 together define a liquid supply chamber 11 formed within the outer casing. A liquid outlet 12 is disposed on the cover 15 or the housing 10. In some embodiments, such as... Figure 3 As shown, a hollow housing 10 has an opening 14 on one side, and a cover 15 is installed at the opening 14. A first sealing member 13 can be pre-placed inside the housing 10 through the opening 14, and then the opening 14 is sealed by the cover 15 to form a liquid supply chamber 11 for storing the atomizing matrix inside the housing. Further, in some embodiments, the housing has a connection surface for connecting with the atomizing assembly, and a liquid outlet 12 is opened on the connection surface. The liquid outlet 12 communicates with the liquid supply chamber 11. In a first state, the first sealing member 13 is disposed along the inner wall of the liquid supply chamber 11 and covers the end of the liquid outlet 12 that communicates with the liquid supply chamber 11, preventing the liquid in the storage chamber from flowing out. In some embodiments, the liquid outlet 12 is configured to protrude from the opening of the housing; further, the protruding opening can be part of the connection structure between the liquid reservoir 1 and the atomizing assembly.

[0045] In some embodiments, the first seal 13 includes a proximal end 130 and a distal end 132, the proximal end 130 being connected to the housing 10, and the distal end 132 being configured to close the free end of the outlet 12 under the support of force.

[0046] The first sealing element 13 can adhere to the inner wall of the liquid supply chamber 11 to seal the liquid outlet 12 when it provides its own elastic tension; the first sealing element 13 can also adhere to the inner wall of the liquid supply chamber 11 to seal the liquid outlet 12 under the support of external force.

[0047] In some embodiments, the first seal 13 is made of a plastic material, such as... Figure 7As shown, the proximal end 130 of the first sealing member 13 is made into a sheet shape, and the proximal end 130 surrounds and fits against the inner wall of the liquid supply chamber 11. The distal end 132 of the first sealing member 13 is configured as a free end, and the distal end 132, supported by the elasticity of the plastic material, blocks the end of the liquid outlet 12 near the liquid storage chamber. It can be understood that the first sealing member 13 is approximately horizontal before being inserted into the liquid supply chamber 11. After being wound, the first sealing member 13 is fixed in the liquid supply chamber 11. The tension generated by the winding deformation of the first sealing member 13 causes the first sealing member 13 to be stuck in the liquid supply chamber 11 and prevents it from moving. At the same time, the tension generated by the deformation of the first sealing member 13 causes the part of the first sealing member 13 near the liquid outlet 12 to fit more closely against the inner wall of the liquid supply chamber 11, and the port of the liquid outlet 12 near the liquid supply chamber 11 is blocked by the first sealing member 13.

[0048] Furthermore, the liquid supply chamber 11 is provided with a mounting plate 16, which divides the space of the liquid supply chamber 11 into at least two interconnected small spaces, wherein the space near the liquid outlet 12 can hold the first sealing element 13, such as... Figure 3 As shown, the elongated first sealing element 13 is curled inside the liquid supply chamber 11. The proximal end 130 of the first sealing element 13 is attached to the mounting plate 16, and the distal end 132 is attached to the inner wall of the liquid supply chamber 11 near the liquid outlet 12.

[0049] In some embodiments, such as Figure 7 As shown, an elastic support member 131 is provided between the opposing surfaces of the proximal end 130 and the distal end 132. The support member 131 provides support for the distal end 132 to close the liquid outlet 12. Specifically, the support member 131 can be made of metal or silicone, rubber, or other materials with tensile or elastic properties, such as... Figure 4 As shown, the first sealing element 13 is generally U-shaped, with its end near the liquid outlet 12 being the distal end 132 and its end away from the liquid outlet 12 being the proximal end 130. One end of the support element 131 can be fixed to the inner wall of the liquid supply chamber 11 or the proximal end 130, while the other end of the support element 131 is connected to or abuts against the distal end 132. The length of the support element 131 is slightly greater than the inner diameter of the liquid supply chamber 11 or the distance from the distal end 132 to the proximal end 130 of the first sealing element 13. That is, the support element 131 and the liquid supply chamber 11 are interference-fitted. This can be understood as follows: when the support element 131 supports the first sealing element 13 to seal the liquid outlet 12, the support element 131 is under pressure, and the first sealing element 13 is tightly pressed against the inner wall of the liquid supply chamber 11 by the outward tension of the support element 131, thus sealing the liquid outlet 12. Furthermore, the support element 131 and the first sealing element 13 can be integrally formed.

[0050] In some embodiments, the first seal 13 includes a separable movable member 20 and an elastic member 30, wherein the elastic member 30 is disposed in the liquid supply chamber 11 and connected to the housing, and provides the movable member 20 with a force to close the liquid outlet 12.

[0051] like Figure 8 As shown, the elastic element 30 is a torsion spring, which is fixed inside the liquid supply chamber 11. One torsion arm of the torsion spring abuts against the inner wall of the liquid supply chamber 11. The movable element 20 is connected to the other torsion arm of the torsion spring, and the torsion arm of the torsion spring supports the movable element 20 against the liquid outlet 12. It is understood that the movable element 20 can be at least partially inserted into the liquid outlet 12 to close the liquid outlet 12, or the movable element 20 can be attached to the inner wall of the liquid supply chamber 11 to cover the liquid outlet 12. In some embodiments, the elastic element 30 can also be a spring sheet, which is interference-fitted inside the liquid supply chamber 11. One end of the spring sheet can abut or be fixed inside the liquid supply chamber 11, and the other end of the spring sheet can abut or be connected to the movable element 20. The spring sheet is compressed and deformed by the inner wall of the liquid supply chamber 11, and the tension is transmitted to the movable element 20, forcing the movable element 20 to close the liquid outlet 12 inside the liquid supply chamber 11.

[0052] like Figure 9 As shown, when the reservoir 1 is connected to the atomizing assembly, the movable part 20 is pressed into the liquid supply chamber 11 by the atomizing assembly. When the movable part 20 moves into the liquid supply chamber 11, the elastic part 30 deforms and the liquid outlet 12 is opened.

[0053] In some embodiments, the reservoir 1 in the above embodiments further includes a second seal (17, 18), which is detachably or removably mounted on the outer wall of the housing to seal the outlet 12.

[0054] like Figure 5 As shown, in some embodiments, the reservoir 1 serves as a container for storing and dispensing atomized matrix. A second seal 17 is provided on the outside of the reservoir 1. The second seal 17 can be a removable sealing cap, which is threadedly connected to the outer casing. When the reservoir 1 is in use, the user first removes the second seal 17, and then connects the reservoir 1 to the atomizing assembly.

[0055] In some embodiments, such as Figure 6 As shown, the second seal 18 can also be a breakable sealing layer, such as a plastic film or metal film fixed to the liquid outlet 12.

[0056] When the reservoir 1 is providing liquid supply service, the second seal (17, 18) can be removed or broken, and then a pipe that can be inserted into the outlet 12 is inserted into the outlet 12. The pipe abuts against the first seal 13 in the supply chamber 11, forcing the first seal 13 away from the outlet 12. The atomizing matrix inside the supply chamber 11 can then be injected into the atomizing assembly through the outlet 12 or the pipe.

[0057] In some embodiments, this application provides an electronic atomizer, which includes an atomizing component and a liquid reservoir 1 as described in the above embodiments. The liquid reservoir 1 is detachably connected to the atomizing component, wherein the atomizing component has a liquid storage chamber, and after the liquid reservoir 1 is connected to the atomizing component, the atomizing matrix is ​​transferred from the liquid supply chamber 11 to the liquid storage chamber.

[0058] In some embodiments, the atomizing assembly is provided with a hollow inlet pipe, one end of which is connected to the liquid storage chamber, and the other end of which is exposed outside the atomizing assembly. Further, one end of the inlet pipe is exposed and protrudes from the atomizing assembly. When the atomizing assembly is connected to the liquid storage tank 1, the atomizing assembly is inserted into the liquid storage tank 1 through the inlet pipe. The inlet pipe is inserted into the outlet 12 and abuts against the first seal 13. As the inlet pipe gradually penetrates deeper into the supply chamber 11, it pushes the first seal 13 away from the outlet 12, or pushes the first seal 13 away from the inner wall of the supply chamber near the outlet 12.

[0059] like Figure 4 or Figure 9 As shown, when the reservoir 1 is combined and connected with the atomizing component, the inlet pipe is inserted into the outlet 12 of the reservoir 1 and abuts against the first seal 13. As the inlet pipe gradually penetrates deeper into the supply chamber 11, the first seal 13 is forced away from the outlet 12, and the reservoir 1 is in the second state, so that a gap is created between the first seal 13 and the inner wall of the supply chamber 11. The gap can connect to the outlet 12 or the gap can connect to the inlet pipe. The atomizing matrix in the supply chamber 11 can be input into the reservoir through the outlet 12 or the inlet pipe.

[0060] In some embodiments, the reservoir 1 uses a sealing membrane as a second seal 18 to seal the liquid outlet 12 on the surface of the reservoir 1. When the reservoir 1 is combined and connected with the atomizing assembly, the inlet pipe breaks the second seal 18 that is blocking the inlet, and then the inlet pipe is inserted into the outlet 12 and abuts against the first seal 13 in the supply chamber 11, and pushes the first seal 13 away from the outlet 12. At this time, the reservoir 1 is in the second state: the supply chamber 11 is connected to the reservoir, and the atomizing matrix in the supply chamber 11 can be input into the reservoir from the inlet pipe.

[0061] In some embodiments, when the reservoir 1 is separated from the atomizing assembly, the inlet pipe is removed from the reservoir cavity, and the reservoir 1 is in a first state: the first seal 13 gradually adheres to the inner wall of the supply cavity 11 under its own elasticity or the support of the support member 131, and the outlet 12 is closed.

[0062] The above description is only a part or preferred embodiment of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
