Description

Technical Field

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

[0002] An electronic atomizing device is a device that can convert a liquid matrix into an aerosol.

[0003] Existing electronic atomizing devices typically employ a liquid injection hole structure to facilitate the replenishment of the liquid matrix, and use a liquid injection plug to seal the injection hole to prevent leakage of the liquid matrix.

[0004] In practice, users may cause leakage of the liquid matrix due to errors or negligence in the operating procedure. For example, failure to promptly install the injection plug after the injection operation increases the risk of leakage; or, incorrect orientation of the electronic atomizing device during the injection process also increases the risk of leakage. Utility Model Content

[0005] The purpose of this invention is to provide an atomizer and an electronic atomizing device to avoid the problem of liquid matrix leakage caused by incorrect operation procedures, reduce the complexity of liquid injection operation for users, and improve the user experience.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] An atomizer, comprising:

[0008] The housing has a liquid storage chamber for storing a liquid matrix inside, and the housing has an injection hole communicating with the liquid storage chamber.

[0009] An elastic element includes an abutting portion; the abutting portion abuts against the inner wall of the housing and seals the injection hole;

[0010] The abutment portion can be pushed open under the action of external force, thereby opening the injection hole and injecting liquid matrix into the storage cavity; when the external force is removed, the abutment portion can return to the state of closing the injection hole under its own elasticity.

[0011] As an alternative to the atomizer, the housing has a delivery tube for transporting aerosols; the elastic element includes a retaining portion that is held on the delivery tube.

[0012] As an alternative to the atomizer, the retaining part is constructed as a tubular structure and sleeved on the transmission tube.

[0013] As an alternative to the atomizer, the outer wall of the transmission tube has a first protrusion, and the retaining part abuts against the first protrusion.

[0014] As an alternative to the atomizer, the retaining part and the abutting part are spaced apart, and the elastic member further includes a connecting part that connects the retaining part and the abutting part.

[0015] As an alternative to the atomizer, the inner wall of the housing has a second protrusion, and the connecting portion abuts against the second protrusion.

[0016] As an alternative to the atomizer, the connecting part includes a reinforcing rib that connects the retaining part and the abutting part.

[0017] As an alternative to the atomizer, the atomizer also includes a liquid injection plug movably connected to the housing, the liquid injection plug being used to open or close the liquid injection port.

[0018] As an alternative to the atomizer, the housing is provided with a limiting hole, and the liquid injection plug is provided with a guide post, which slides in the limiting hole.

[0019] As an alternative to the atomizer, the guide post is provided with a limiting boss that can abut against the inner wall of the housing.

[0020] An electronic atomizing device includes a power supply and an atomizer as described in any of the above embodiments. The atomizer includes an atomizing component disposed inside the housing, and the power supply is electrically connected to the atomizing component.

[0021] Beneficial effects:

[0022] In the first aspect of this invention, when the injection hole is opened, the elastic part of the elastic member directly abuts against the inner wall of the housing, thereby sealing the injection hole. This effectively prevents the liquid matrix from leaking from the injection hole due to user error caused by the injection hole not being sealed in time, thus ensuring safety and practicality. On the other hand, if the injection hole is not in the upward position due to user error after it is opened, the risk of leakage will also increase during the injection process. This atomizer still directly abuts against the inner wall of the housing through the elastic part of the elastic member. Even if the injection hole is not upward, it can still prevent liquid matrix leakage, thereby effectively reducing the complexity of the user's injection operation and improving the user experience.

[0023] In a second aspect of this invention, the electronic atomizing device based on this atomizer can effectively prevent the liquid matrix from leaking from the injection hole due to user error when the user fails to seal the injection hole in time; in addition, it can also avoid the risk of leakage due to user operation errors during the injection process, reduce the complexity of the user's injection operation, and improve the user's experience.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0035] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0037] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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 utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] Please see the appendix Figure 1 - Appendix Figure 5 The first aspect of this embodiment relates to an atomizer, which includes a housing 1 and an elastic member 2. The housing 1 has a liquid storage chamber 11 for storing a liquid matrix, and an injection hole 12 communicating with the liquid storage chamber 11. The elastic member 2 includes an abutment portion 21; the abutment portion 21 abuts against the inner wall of the housing 1 and closes the injection hole 12; the abutment portion 21 can be opened by an external force, thereby opening the injection hole 12 and injecting the liquid matrix into the liquid storage chamber 11; when the external force is removed, the abutment portion 21 can return to the state of closing the injection hole 12 under its own elasticity.

[0039] Specifically, the housing 1 is made of non-metallic material and can be made of transparent material, allowing the user to easily observe the remaining amount of liquid matrix inside the storage chamber 11 through the housing 1, assisting the user in determining whether to add liquid matrix to the storage chamber 11. An outlet for aerosol discharge is provided on the top wall of the housing 1. An injection hole 12 is provided on the side wall of the housing 1, and the shape of the injection hole 12 includes, but is not limited to, circular and elliptical shapes. The elastic element 2 can be made of silicone material, and the abutment part 21 is plate-shaped and placed inside the housing 1. The abutment part 21 can abut against the inner wall of the housing 1 through its own elasticity and seal the injection hole 12. In the non-liquid-filled free state, the abutment part 21 is always pressed against the inner wall of the housing 1. When it is necessary to inject liquid matrix into the liquid storage chamber 11, the user can use the injection component to forcefully push open the abutment part 21 to open the injection hole 12. After the liquid filling is completed, the user can sequentially remove the injection component from the liquid storage chamber 11 and the injection hole 12. The abutment part 21 then uses its elasticity to abut against the inner wall of the housing 1, thereby returning the injection hole 12 to a closed state. Since the gap between the liquid storage chamber 11 and the abutment part 21 is filled with liquid matrix, the injection hole 12 forms a sealed state to prevent liquid matrix leakage.

[0040] In this embodiment, on the one hand, when the injection hole 12 is open, the elastic part 21 of the elastic member 2 can directly abut against the inner wall of the housing 1 through its own elasticity, thereby sealing the injection hole 12. This effectively avoids the problem of liquid matrix leakage from the injection hole 12 caused by user error due to improper operation if the injection hole 12 is not sealed in time, thus ensuring safety and practicality. On the other hand, during the injection process after the injection hole 12 is open, if the injection hole 12 is not in the upward position due to user operation error, the risk of leakage will also increase. This atomizer can still directly abut against the inner wall of the housing 1 through the elastic part 21 of the elastic member 2. Even if the user does not place the injection hole 12 in the upward position, the leakage of liquid matrix can still be avoided, thereby effectively reducing the complexity of the user's injection operation and improving the user experience. In addition, since the gap between the liquid storage chamber 11 and the contact part 21 is filled with liquid matrix, it plays a liquid sealing role, which can also reduce the risk of leakage caused by the injection hole 12 opening in a short time or the injection hole 12 not facing upward.

[0041] Please refer to the appendix for further information. Figure 2 - Appendix Figure 5 Optionally, the housing 1 has a transmission tube 13 for transmitting aerosols; the elastic member 2 includes a retaining part 22, which is held on the transmission tube 13.

[0042] Specifically, the transmission pipe 13 can be a tubular body formed by the housing 1 extending from the air outlet into the liquid storage chamber 11. The transmission pipe 13 has a first channel 131 inside, which communicates with the air outlet and is used to discharge aerosols. The elastic member 2 is connected to the transmission pipe 13 via the retaining part 22, thus fixing the elastic member 2 relative to the transmission pipe 13. The elastic member 2 can be connected to the transmission pipe 13 using a detachable connection method such as snap-fit ​​or interference fit, or it can be fixed to the transmission pipe 13 by adhesive bonding. The specific method can be selected based on usage requirements and ease of installation.

[0043] In this embodiment, the elastic element 2 is directly disposed on the transmission pipe 13, which simplifies the connection parts and improves the convenience of connection.

[0044] Furthermore, the retaining part 22 is constructed as a tubular structure and is sleeved on the transmission pipe 13.

[0045] In this embodiment, the retaining part 22 is formed into a tubular structure and is directly sleeved on the outer wall of the transmission pipe 13, making the installation method simple and reliable.

[0046] Optionally, the outer wall of the transmission tube 13 has a first protrusion 132, and the retaining part 22 abuts against the first protrusion 132.

[0047] In this embodiment, the first boss 132 can be integrally formed on the outer wall of the transmission pipe 13, or it can be a structure independent of the transmission pipe 13 and sleeved on the outer wall of the transmission pipe 13. The first boss 132 abuts against the end face of the retaining part 22 in the axial direction of the transmission pipe 13, thereby limiting the retaining part 22 in the axial direction of the transmission pipe 13 and ensuring the reliability of the assembly.

[0048] Optionally, the retaining part 22 and the abutting part 21 are spaced apart, and the elastic member 2 also includes a connecting part 23 that connects the retaining part 22 and the abutting part 21.

[0049] Specifically, the transfer pipe 13 is located in the middle or near the middle of the housing 1, the injection hole 12 is provided on the side wall of the housing 1, and the space between the transfer pipe 13 and the side wall of the housing 1 forms a liquid storage cavity 11. The holding part 22, the connecting part 23 and the abutting part 21 are integrally formed structures.

[0050] In this embodiment, the connection part 23 can facilitate the independent installation function of the retaining part 22 and the sealing function of the abutment part 21, while also taking into account the spatial adaptability between the transmission pipe 13 and the side wall of the housing 1, and avoiding the retaining part 22 and / or the abutment part 21 being too large and occupying more space in the liquid storage chamber 11.

[0051] Furthermore, the inner wall of the housing 1 has a second protrusion 15, and the connecting part 23 abuts against the second protrusion 15.

[0052] A second boss 15 is also provided on the inner wall of the housing 1. The end of the connecting part 23 abuts against the second boss 15, and the retaining part 22 abuts against the first boss 132, so that the elastic member 2 can be reliably fixed in the axial direction of the transmission tube 13.

[0053] Optionally, the connecting part 23 includes a reinforcing rib 24, which connects the retaining part 22 and the abutting part 21.

[0054] In this embodiment, the reinforcing rib 24 can also be integrally formed on the connecting part 23. By connecting the retaining part 22 and the abutting part 21 at both ends of the reinforcing rib 24, the overall rigidity of the elastic member 2 can be improved, ensuring that the abutting part 21 has sufficient abutting pressure on the inner wall of the housing 1, thereby improving the reliability of the abutting part 21 in sealing the injection hole 12.

[0055] Optionally, the atomizer also includes a liquid injection plug 4 movably connected to the housing 1, which is used to open or close the liquid injection port 12. That is, the liquid injection plug 4 is used to insert into the liquid injection port 12 so that the liquid injection port 12 is in the closed state; the liquid injection plug 4 is used to pull out of the liquid injection port 12 so that the liquid injection port 12 is in the open state.

[0056] Specifically, the injection plug 4 is an elastic rubber plug. The rubber plug is interference-fitted into the injection hole 12 by its own elasticity, so that the injection hole 12 is in a closed state. When it is necessary to inject liquid matrix into the liquid storage chamber 11, the injection plug 4 can be manually pulled out to open the injection hole 12.

[0057] Furthermore, a guide post 41 is integrally formed on the injection plug 4, and a limiting hole 14 is opened on the housing 1 near the injection hole 12, with the guide post 41 sliding in the limiting hole 14.

[0058] In this embodiment, the guide post 41 can provide guidance for the insertion and removal of the injection plug 4, thereby improving the operability of insertion and removal and the user experience.

[0059] Furthermore, the guide post 41 is provided with a limiting boss 411 around its circumference, and the limiting boss 411 can abut against the inner wall of the housing 1.

[0060] Specifically, the limiting boss 411 is arranged in a ring shape, and the limiting boss 411 is conical or cylindrical in the axial direction of the guide post 41. The radial dimension of the limiting boss 411 is larger than the radial dimension of the limiting hole 14. Thus, after the liquid injection plug 4 is pulled out, the end face of the limiting boss 411 abuts against the inner wall of the housing 1, so that the guide post 41 cannot be completely pulled out of the limiting hole 14. This effectively avoids the easy loss of the liquid injection plug 4 due to separation from the housing 1 after being pulled out, and improves the practicality of the atomizer.

[0061] The second aspect of this embodiment relates to an electronic atomizing device, which includes a power supply and an atomizer. The atomizer includes an atomizing component 3 disposed inside a housing 1, and the power supply is electrically connected to the atomizing component 3.

[0062] In this embodiment, the power supply is used to supply power to the atomizing component 3. The atomizing component 3 is provided with a second channel 31. The atomizing component 3 passes the liquid matrix into the aerosol formed by atomization into the second channel 31. The second channel 31 is connected to the first channel 131. The aerosol is then discharged to the air outlet through the first channel 131 for use.

[0063] The electronic atomization device based on this atomizer can effectively prevent the liquid matrix from leaking from the injection hole 12 due to user error when the user fails to seal the injection hole 12 in time. In addition, it can also avoid the risk of leakage due to user operation error during the injection process, reduce the complexity of the user's injection operation, and improve the user experience.

[0064] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
