Description

Technical Field

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

[0002] With the development of technology and the improvement of people's living standards, electronic devices are becoming increasingly common in people's lives. Among them, the atomizer, as the main part of the atomizing device, plays a relatively important role.

[0003] In existing technology, the atomizer housing is equipped with a liquid injection plug, and liquid is added to the housing by opening the cap of the liquid injection plug. However, if too much force is used when opening the cap, the entire liquid injection plug can easily detach from the housing, resulting in leakage. Utility Model Content

[0004] This application provides an atomizer and atomizing device to solve the problem that the entire liquid injection plug is easily detached from the housing and causes leakage when the cap of the liquid injection plug is opened.

[0005] In one embodiment, an atomizer is provided, the atomizer including a housing and a liquid injection plug fixed to the housing; the liquid injection plug includes a fixing portion, a connecting portion, and a cap portion, the connecting portion being connected between the fixing portion and the cap portion, the fixing portion being configured to fix the liquid injection plug in the housing; the connecting portion having a pre-fracture structure, the pre-fracture structure being configured to preferentially fracture when the liquid injection plug is subjected to a predetermined tensile force, such that the cap portion detaches from the fixing portion and the fixing portion remains in the housing.

[0006] In some embodiments, the material thickness or cross-sectional area of ​​the pre-fractured structure is smaller than that of other portions of the connection, wherein the dimensions of the pre-fractured structure are configured such that the connection strength between the fixing portion and the cover portion is less than the retention strength between the fixing portion and the housing.

[0007] In some embodiments, the fixing part, the connecting part, and the cover part are integrally formed.

[0008] In some embodiments, the pre-fracture structure is configured as a notch, which is provided in at least one side of the connection.

[0009] In some embodiments, the notch includes a first notch and a second notch symmetrically disposed on both sides of the connector.

[0010] In some embodiments, the direction from the fixing portion to the cover portion is a first direction, and the notch includes a stress concentration portion located on the vertical line of the connecting portion along the first direction.

[0011] In some embodiments, the notch is constructed as a triangular, V-shaped, or U-shaped notch.

[0012] In some embodiments, the depth of the notch is any value between 0.5 and 0.7 mm.

[0013] In some embodiments, the pre-fracture structure is configured as a material thinning portion; the thickness of the material thinning portion is any value between 0.15 and 0.2 mm.

[0014] In some embodiments, this application also provides an atomizing device, which includes the aforementioned atomizer.

[0015] According to the atomizer of the above embodiment, a pre-fracture structure is provided on the connecting part between the fixing part and the cover part. When the liquid injection plug is subjected to a predetermined tensile force, the pre-fracture structure is prone to breakage, causing the connecting part to break first, thus weakening the structural strength of the connecting part. This allows the cover part to detach from the fixing part, while the fixing part remains in the housing. This provides a good sealing effect between the fixing part and the housing, preventing the liquid injection plug from completely detaching from the housing and causing leakage when subjected to a large tensile force. It also has a good child lock function, preventing children from pulling the liquid injection plug out completely, thus giving the atomizer good safety and leak-proof effect.

Detailed Implementation

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

[0020] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0021] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0022] Throughout this application, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0023] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] In related technologies, the injection plug has a child lock function, meaning that when the injection plug is pulled, the part that is locked to the shell will not be pulled off, preventing leakage. Related technologies typically increase the locking amount of the injection plug's fixing part to prevent it from being pulled out under strong force. However, in actual production, variations in the size and hardness of the injection plug lead to instances where the child lock fails, meaning the injection plug can be pulled off entirely. Furthermore, increasing the locking amount makes assembly difficult, affecting production efficiency. Alternatively, related technologies may reduce the size of certain areas of the injection plug, but this affects the overall appearance of the atomizer, resulting in poor aesthetics.

[0025] In this application, a pre-fracture structure is provided on the connection between the fixing part and the cover part. When the injection plug is subjected to a predetermined tensile force, the pre-fracture structure is prone to breakage, causing the connection part to break first. This weakens the structural strength of the connection part, thereby causing the cover part to detach from the fixing part while the fixing part remains in the housing. This provides a good sealing effect between the fixing part and the housing, preventing the injection plug from completely detaching from the housing and causing leakage when subjected to a large tensile force. It also has a good child lock function, preventing children from pulling the injection plug out as a whole, thus giving the atomizer better safety and leak-proof effect.

[0026] Reference Figures 1 to 6 In one embodiment, this application provides an atomizer, the atomizer including a housing 1 and a liquid injection plug 2 fixed to the housing 1.

[0027] The injection plug 2 includes a fixing part 21, a connecting part 22 and a cover part 23. The connecting part 22 is connected between the fixing part 21 and the cover part 23. The fixing part 21 is configured to fix the injection plug 2 in the housing 1.

[0028] The connecting part 22 is provided with a pre-fracture structure, which is configured to break preferentially when the injection plug 2 is subjected to a predetermined tensile force, so that the cover part 23 is detached from the fixing part 21 and the fixing part 21 is retained in the housing 1.

[0029] In some embodiments of this application, the pre-fracture structure refers to a structure that can weaken the structural strength or hardness of the connecting part 22. By providing a pre-fracture structure on the connecting part 22 located between the fixing part 21 and the cover part 23, the pre-fracture structure is easily broken when the injection plug 2 is subjected to a predetermined tensile force, causing the connecting part 22 to break first, thus weakening the structural strength of the connecting part 22. This allows the cover part 23 to detach from the fixing part 21, while the fixing part 21 remains in the housing 1, so that the fixing part 21 still has a sealing function with the housing 1. This prevents the injection plug 2 from completely detaching from the housing 1 and causing leakage when subjected to a large tensile force, thus providing a good child lock function. This prevents children from pulling the injection plug 2 out completely, giving the atomizer better safety and leak-proof effect.

[0030] In some embodiments of this application, the predetermined tensile force is the tensile force experienced when the pre-fracture structure fractures, and its specific value can be set according to actual needs. For example, the predetermined tensile force can be any value between 10-15N, such as 10N, 13N, or 15N, etc. The specific value of the predetermined tensile force is not limited in the embodiments of this application.

[0031] In some embodiments of this application, the fixing part 21 and the cover part 23 are spaced apart, and the connecting part 22 is located between the fixing part 21 and the cover part 23. The fixing part 21 can be snapped onto or abutted against the inner wall of the housing 1, and the cover part 23 can be movably connected to the outer wall of the housing 1. That is, the cover part 23 can cover the housing 1 for sealing, or the cover part 23 can be flipped under the action of external force to release the sealing of the housing 1, so as to facilitate the replenishment of liquid into the housing 1.

[0032] In some embodiments of this application, for example, the injection plug 2 can be made of silicone or rubber, which has good flexibility and elasticity, and is beneficial to extending the service life of the injection plug 2. The specific material of the injection plug 2 is not limited in the embodiments of this application.

[0033] In some embodiments of this application, the material thickness or cross-sectional area of ​​the pre-fracture structure is smaller than that of other portions of the connecting portion 22. The dimensions of the pre-fracture structure are configured such that the connection strength between the fixing portion 21 and the cover portion 23 is less than the retention strength between the fixing portion 21 and the housing 1. Thus, because the material thickness of the pre-fracture structure is smaller than that of other portions of the connecting portion 22, the pre-fracture structure has lower structural strength than other portions of the connecting portion 22, making it more prone to fracture under externally applied tensile force. Similarly, because the cross-sectional area of ​​the pre-fracture structure is smaller than that of other portions of the connecting portion 22, the pre-fracture structure also has lower structural strength than other portions of the connecting portion 22, making it more prone to fracture under externally applied tensile force.

[0034] Furthermore, under the action of the pre-fracture structure, the connection strength between the fixing part 21 and the cover part 23 is less than the fixing strength between the fixing part 21 and the housing 1. Therefore, when subjected to a predetermined tensile force, the part with a smaller connection strength between the fixing part 21 and the cover part 23 is more likely to break, while the fixing part 21 and the housing 1 have better connection stability due to the greater fixing strength. This keeps the fixing part 21 in the housing 1 and achieves a better sealing effect on the housing 1.

[0035] In some embodiments of this application, the connection strength between the fixing part 21 and the cover part 23 refers to the maximum pulling force required to detach the cover part 23 from the fixing part 21. The fixing and retaining strength between the fixing part 21 and the housing 1 refers to the maximum pulling force required to pull the fixing part 21 out of the housing 1.

[0036] In some embodiments of this application, the fixing part 21, the connecting part 22, and the cover part 23 are integrally formed, which makes the fixing part 21, the connecting part 22, and the cover part 23 have good integrity, facilitates assembly, and helps to reduce material loss and manufacturing processes during production.

[0037] See Figure 4 In some embodiments of this application, the pre-fracture structure can be constructed as a notch 221, which penetrates the connecting portion 22. The notch 221 forms the pre-fracture structure, reducing the overall thickness of the connecting portion 22 and thus significantly reducing its structural strength. This design is simple, easy to operate, and readily achievable. The notch 221 is disposed in at least one side of the connecting portion 22. That is, the notch 221 can be disposed on one side of the connecting portion 22, or on another side of the connecting portion 22, or simultaneously on both sides of the connecting portion 22. The specific location of the notch 221 is not limited in the embodiments of this application.

[0038] In some embodiments of this application, the pre-fracture structure is constructed as a groove structure. The groove structure does not penetrate the connecting part 22. The pre-fracture structure is formed by the groove structure, which weakens the thickness of the connecting part 22, thereby greatly reducing the structural strength of the connecting part 22. The structure is simple, easy to operate, and easy to implement.

[0039] In some embodiments of this application, for example, the notch 221 can be provided on the side of the connecting portion 22 near the housing 1, that is, the notch 221 can be provided on the inner side of the connecting portion 22. In this way, the liquid injection plug 2 has a better appearance, avoids damaging the overall structure of the atomizer, and improves its aesthetics.

[0040] For example, in some embodiments of this application, a notch 221 can be provided in the connection part 22 according to stress requirements, or multiple notches 221 can be provided at different positions of the connection part 22 to form a pre-fracture structure. The notches can be set according to actual needs. The specific setting position and number of notches 221 are not limited in the embodiments of this application.

[0041] In some embodiments, the notch 221 includes a first notch 2211 and a second notch 2212 symmetrically arranged on both sides of the connecting portion 22. That is, the first notch 2211 can be provided on one side of the connecting portion 22, and the second notch 2212 can be provided on the other side of the connecting portion 22. In this way, the first notch 2211 and the second notch 2212 are respectively provided on both sides of the connecting portion 22, making the notch positions on both sides of the connecting portion 22 relatively weak, which is easy to break under greater tension, thus having a fracture guiding function. Moreover, the symmetrical arrangement of the first notch 2211 and the second notch 2212 makes the force on the connecting portion 22 more balanced, with better fracture stability, which is conducive to more precise control of the fracture position, avoiding damage to the fixing portion 21, thereby more reliably realizing the safety function of the child lock.

[0042] In some embodiments of this application, the direction from the fixing part 21 to the cover part 23 is the first direction X. The notch 221 includes a stress concentration part 2213, which is located on the perpendicular bisector 222 of the connecting part 22 along the first direction X. Thus, when subjected to a large external force, the stress will be concentrated at the stress concentration part 2213, making the notch 221 more prone to tearing at the stress concentration part 2213. For example, the stress concentration part 2213 can be a sharp-angled structure. Furthermore, since the stress concentration part 2213 is located on the perpendicular bisector 222 of the connecting part 22 along the first direction X, the connecting part 22 is more likely to break at the perpendicular bisector 222, achieving more precise control of the fracture path. This makes the fracture process and fracture structure more controllable, preventing irregular fractures or structural twisting of the connecting part 22 that could affect the tightness of the fixing part 21.

[0043] In some embodiments, the notch 221 is constructed as a triangular, V-shaped, or U-shaped notch. This allows the notch shape to be formed using triangular, V-shaped, or U-shaped structures, resulting in a simple and easily implemented structure. Furthermore, the apex of the triangular or V-shaped structure has a sharp corner, which can form a stress concentration point 2213. Additionally, the triangular or V-shaped structure exhibits good structural stability even when not subjected to external force, resulting in good structural integrity for both the connecting portion 22 and the injection plug 2 as a whole.

[0044] In some embodiments of this application, the depth of the notch 221 is any value between 0.5 and 0.7 mm. The depth of the notch 221 refers to the vertical distance between the deepest point of the notch 221 and the material surface. This allows the pre-fracture structure to better control the breaking force of the connection 22 in the depth direction, ensuring sufficient rigidity of the connection 22 under normal use without significant external force. Furthermore, even under more severe external force, the connection 22 can break, keeping the fixing part 21 fixed to the housing 1, effectively preventing leakage of the child lock. This avoids the notch 221 being too shallow to break easily and thus affecting the fixing part 21, and also avoids the notch 221 being too deep, making the structural strength of the connection 22 too weak to achieve normal use.

[0045] For example, in some embodiments of this application, the depth of the notch 221 can be 0.5mm, 0.6mm or 0.7mm, etc., and can be set according to the actual stress requirements and the size of the connection part 22, etc. The specific value of the depth of the notch 221 is not limited in the embodiments of this application.

[0046] In some embodiments, for example, such as Figure 4 As shown, the direction from the fixing part 21 to the cover part 23 is the first direction X, and the connecting part 22 extends along the second direction Y, which is perpendicular to the first direction X. The dimension of the notch 221 along the second direction Y can be any value between 0.5-0.7mm, and the dimension of the notch 221 along the first direction X can also be any value between 0.5-0.7mm. This allows the pre-fracture structure to better control the breaking force of the connecting part 22 along the first direction X, ensuring sufficient rigidity for the connecting part 22 under normal use without significant external force, and timely breakage under relatively strong external force to keep the fixing part 21 locked onto the housing 1, effectively preventing leakage of the child lock. This avoids the notch 221 being too small to break easily and affect the fixing part 21, and also avoids the notch 221 being too large, making the structural strength of the connecting part 22 too weak to achieve normal use.

[0047] For example, in the embodiments of this application, the size of the notch 221 along the first direction X can be 0.5mm, 0.6mm or 0.7mm, etc., and can be set according to the actual stress requirements and the size of the connecting part 22, etc. The specific value of the size of the notch 221 along the first direction X is not limited in the embodiments of this application.

[0048] In some embodiments, the pre-fracture structure is constructed as a material thinning portion 223, the thickness of which is any value between 0.15-0.2 mm. Thus, the material thickness of the pre-fracture structure is less than that of other parts of the connecting portion 22, resulting in a suitable thickness for the material thinning portion 223. This ensures sufficient rigidity of the connecting portion 22 under normal use without significant external force, and allows for timely breakage under strong external force, keeping the fixing portion 21 locked onto the housing 1, effectively preventing leakage of the child lock. This avoids the material thinning portion 223 being too thick to break easily and thus affecting the fixing portion 21, and also avoids the material thinning portion 223 being too thin, resulting in insufficient structural strength of the connecting portion 22 and hindering normal use. For example, as... Figure 3 As shown, the thickness of the material thinning portion 223 extends along the third direction Z, which is perpendicular to the first direction X and the second direction Y.

[0049] In some embodiments, the atomizer includes a liquid injection component 3, the housing 1 has a liquid injection hole 11, the liquid injection component 3 seals the liquid injection hole 11, and the cover 23 movably covers the liquid injection component 3 from the outside. The liquid injection component 3 has a through cut 31. In this way, liquid can be added to the housing 1 through the cut 31. After the liquid is added, the cut 31 can automatically return to its initial shape under the action of elasticity, improving the sealing performance and reducing the risk of leakage due to the opening in the liquid injection component 3.

[0050] For example, in some embodiments of this application, the injection element 3 can be made of rubber or silicone, giving it good elasticity and toughness. The specific material of the injection element 3 in this application embodiment is not limited. The cut 31 can be a T-shaped cut 31, which has a good sealing effect. In addition, the cut 31 can also be a cross-shaped or V-shaped cut, etc. The specific type of cut 31 in this application embodiment is not limited.

[0051] In one or more embodiments of this application, for example, the housing 1 has a liquid storage chamber. When replenishment is required, the cover 23 can be flipped or rotated to open the cover 23, exposing the liquid injection component 3, so that the liquid injection device can be inserted into the liquid storage chamber inside the housing 1 through the cut 31 for liquid injection. After replenishment is completed, the cover 23 can be flipped or rotated in the opposite direction to seal the liquid injection hole 11, thus sealing the liquid injection component 3 to prevent exposure.

[0052] In summary, the atomizer described in the embodiments of this application may include at least the following advantages: In this embodiment, the atomizer includes a housing and a liquid injection plug fixed to the housing. The liquid injection plug includes a fixing part, a connecting part, and a cap. The connecting part connects the fixing part and the cap. The fixing part is configured to fix the liquid injection plug in the housing. The connecting part is provided with a pre-fracture structure, which is configured to break preferentially when the liquid injection plug is subjected to a predetermined tensile force, so that the cap detaches from the fixing part while the fixing part remains in the housing. Thus, by providing a pre-fracture structure on the connecting part located between the fixing part and the cap, the pre-fracture structure is easily broken when the liquid injection plug is subjected to a predetermined tensile force, causing the connecting part to break preferentially. This weakens the structural strength of the connecting part, thereby allowing the cap to detach from the fixing part while the fixing part remains in the housing. This provides a good sealing effect between the fixing part and the housing, preventing the liquid injection plug from completely detaching from the housing and causing leakage when subjected to a large tensile force. It also provides a good child lock function, preventing children from pulling the liquid injection plug out completely, thus giving the atomizer good safety and leak-proof performance.

[0053] In some embodiments, this application also provides an atomizing device, which includes the aforementioned atomizer.

[0054] For example, the atomizing device may also include a power supply structure that provides electrical energy to the atomizer. In some embodiments, the power supply structure and the atomizer are fixedly connected, resulting in a simple structure; in other embodiments, the power supply structure and the atomizer are detachably connected, allowing them to be replaced as needed, thus improving energy efficiency and environmental friendliness.

[0055] The atomizing device described in this application embodiment may include at least the following advantages: In this embodiment, the atomizing device includes the atomizer, which includes a housing and a liquid injection plug fixed to the housing. The liquid injection plug includes a fixing part, a connecting part, and a cover part. The connecting part is connected between the fixing part and the cover part. The fixing part is configured to fix the liquid injection plug in the housing. The connecting part is provided with a pre-fracture structure, which is configured to break preferentially when the liquid injection plug is subjected to a predetermined tensile force, so that the cover part is detached from the fixing part and the fixing part is retained in the housing. In this way, a pre-fracture structure is provided on the connection between the fixing part and the cover part. When the injection plug is subjected to a predetermined tensile force, the pre-fracture structure is prone to breakage, causing the connection part to break first. This weakens the structural strength of the connection part, thereby allowing the cover part to detach from the fixing part while the fixing part remains in the housing. This provides a good sealing effect between the fixing part and the housing, preventing the injection plug from completely detaching from the housing and causing leakage when subjected to a large tensile force. It also has a good child lock function, preventing children from pulling the injection plug out as a whole, thus giving the nebulizer good safety and leak-proof effect.
