Description

Technical Field

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

[0002] Atomizers are products that heat an aerosol substrate through an atomizer, generating an aerosol without burning it. To meet diverse user needs, some atomizers have a liquid injection port on the housing, allowing users to add the desired aerosol substrate.

[0003] The current liquid injection hole is usually sealed by a silicone plug set on the outside of the shell. After the user finishes adding the atomized matrix, the silicone plug needs to be pressed into place to achieve the sealing effect. Because the silicone plug has an interference fit with the shell, it requires sufficient force to press it into place. If it is not pressed into place, liquid leakage will occur. In addition, if the user forgets or fails to plug the silicone plug in time after adding, it will also cause the internal seal to fail, and the atomized matrix will seep out from the inside of the liquid storage component. Therefore, this solution has a low tolerance for user operation errors. If the user operates improperly, liquid leakage is likely to occur. Utility Model Content

[0030] The present invention is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted under different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0031] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0032] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0033] When the atomizer seals the liquid injection hole with a silicone plug provided on the outside of the housing, the user needs to manually open the silicone plug to add the atomized matrix. After finishing, the user needs to manually close the silicone plug and press it into place to achieve a seal. Because the silicone plug has an interference fit with the housing, it requires sufficient force to press it into place. If it is not pressed into place, liquid leakage will occur. In addition, if the user forgets or fails to tighten the plug in time after adding, the seal inside the atomizer will fail, and the atomized matrix will seep out from the inside of the atomizer core. Therefore, this solution has a low tolerance for user operation errors. If the user operates improperly, liquid leakage is likely to occur. Therefore, to solve the above problems, the present application provides a sealing element in the housing, and the elastic portion of the sealing element forms a seal on the liquid injection hole. Because the elastic portion is elastically deformable, the elastic portion can be forced to open and automatically rebound when adding the atomized matrix, without the need for additional opening and closing actions. This makes it less likely for users to make mistakes during operation and avoids liquid leakage caused by the user forgetting to close the liquid injection hole or the silicone plug not being pressed into place.

[0034] Please refer to Figures 1 to 8 In one embodiment, an atomizer is provided. The atomizer includes a housing 1, a sealing element 2, and other functional components as needed, which are described in detail below.

[0035] like Figure 1 、 Figure 2 In this embodiment, a liquid storage chamber 103 for storing the atomized matrix is ​​provided in the shell 1 , and a liquid injection hole 101 is provided on the shell 1 , which is communicated with the liquid storage chamber 103 .

[0036] It is understandable that the housing 1 in this embodiment may be made of, but not limited to, plastic material, and in some embodiments, may also be made of metal. The liquid storage chamber 103 in this embodiment may be a cavity structure formed integrally when the housing 1 is formed, or may be a liquid storage component fixed in the housing 1, and the liquid storage chamber 103 is arranged in the liquid storage component. The injection hole 101 in this embodiment is a through hole on the housing 1, that is, one end of the injection hole 101 penetrates into the liquid storage chamber 103, and the other end penetrates into the outer wall of the housing 1, so that an atomized matrix can be added to the liquid storage chamber 103 through the injection hole 101. The housing 1 in this embodiment is not limited to the above structure, and other functional structures may be provided thereon, for example, the housing 1 may also be provided with an airway and an air port for the circulation of the aerosol formed by atomization. The atomized matrix in this embodiment may be a medicinal liquid, a cigarette oil, or other liquid matrix that can be atomized.

[0037] In this embodiment, if Figure 1 、 Figure 2 In this embodiment, one end of the shell 1 has an opening 102, which receives the sealing element 2. The sealing element 2 includes a fixed portion 202 and an elastic portion 201 extending toward the liquid injection hole 101. The outer periphery of the fixed portion 202 is sealed with the inner wall of the shell 1, and at least part of the elastic portion 201 elastically fits the inner wall of the liquid storage cavity 103 and blocks the liquid injection hole 101; the elastic portion 201 can be deformed under the action of the thrust applied from the liquid injection hole 101 to open the liquid injection hole 101, and restore the deformation to block the liquid injection hole 101 after the thrust is removed.

[0038] It can be understood that the sealing element 2 can simultaneously form a seal on the opening 102 and the liquid injection hole 101 of the shell 1, thereby reducing the number of parts of the atomizing device, saving costs, and being more conducive to assembly. When the fixing portion 202 is fixed in the opening 102, a hole or groove for inserting or passing the parts of the power supply assembly can be provided on the fixing portion 202, and a bottom cover can be provided at the opening 102 of the shell 1 to cover the opening 102. The bottom cover and the shell 1 can be fixedly connected by, but not limited to, snap-fitting. The opening 102 provided in this embodiment facilitates the assembly of the internal components of the shell 1 and also facilitates the cleaning of the liquid storage chamber 103. In this embodiment, the fixing portion 202 can be interference fit in the opening 102, forming a sealed fit between the outer periphery of the fixing portion 202 and the inner wall of the shell 1. The elastic portion 201 in this embodiment is elastically deformable. The elastic portion 201 is located within the liquid storage chamber 103 and conforms to the inner wall of the liquid storage chamber 103. That is, the elastic portion 201 is in close contact with the inner wall of the liquid storage chamber 103, thereby allowing the elastic portion 201 to seal and cover the liquid injection hole 101. In this embodiment, the elastic portion 201 can partially or completely conform to the inner wall of the liquid storage chamber 103, as long as the elastic portion 201 can cover and seal the liquid injection hole 101. To improve sealing performance, the elastic portion 201 includes at least a portion corresponding to the liquid injection hole 101 and a portion corresponding to the outer periphery of the liquid injection hole 101. That is, the width of the elastic portion 201 is greater than the width of the liquid injection hole 101. In this embodiment, the elastic portion 201 has a state of blocking the injection hole 101 and a state of not blocking the injection hole 101. When blocked, the injection hole 101 is sealed by the elastic portion 201. When not blocked, the elastic portion 201 is pushed and deformed by an external force applied through the injection hole 101, and the injection hole 101 is opened for adding atomized matrix.

[0039] When adding aerosolized substrate, a thrust is applied to the elastic portion 201 through the liquid injection hole 101, causing the elastic portion 201 to elastically deform and move away from the liquid injection hole 101, thereby opening the liquid injection hole 101. The added aerosolized substrate can then be added to the liquid storage chamber 103 through the liquid injection hole 101. After the addition is complete, the thrust is removed, and the elastic portion 201 automatically rebounds and recovers its deformation. After rebounding, the elastic portion 201 returns to the state of blocking the liquid injection hole 101. The automatic rebound of the elastic portion 201 is fast and reliable, solving the problem of poor sealing and liquid leakage caused by improper user operation, improving the sealing stability and effectiveness of the aerosol device, and preventing leakage of the aerosolized substrate.

[0040] like Figure 3-Figure 6 In this embodiment, the fixing portion 202 and the elastic portion 201 are integrally formed. The elastic portion 201 is in a cantilever shape away from the fixing portion 202 . The distal end 204 of the elastic portion 201 away from the fixing portion 202 blocks the liquid injection hole 101 .

[0041] It is understood that the fixed portion 202 and the elastic portion 201 in this embodiment can be an integral structure, and the material of the fixed portion 202 and the elastic portion 201 can be the same; in some application scenarios, the fixed portion 202 and the elastic portion 201 can also be separate, and the elastic portion 201 is fixed to the fixed portion 202 by a connection. When they are separate, the materials of the elastic portion 201 and the fixed portion 202 can be the same or different. In this embodiment, the elastic portion 201 is made of a material that can undergo elastic deformation, such as but not limited to silicone. The material of the fixed portion 202 can also be the same silicone material as the elastic portion 201. During the manufacturing process, the sealing element 2 including the fixed portion 202 and the elastic portion 201 can be formed integrally. The cantilever shape in this embodiment refers to the shape of the elastic portion 201 in the sealing element 2, with one end of the elastic portion 201 fixedly connected to the fixed portion 202 and the other end of the elastic portion 201 being a free end away from the fixed portion 202. The elastic portion 201 is cantilevered, so that when it is pushed by an external force passing through the liquid injection hole 101, the elastic portion 201 can swing around the portion connected to the fixed portion 202 and away from the inner wall of the liquid storage chamber 103. After the elastic portion 201 swings, the elastic portion 201 does not block the liquid injection hole 101, and the liquid storage chamber 103 is connected to the outside of the shell 1 through the liquid injection hole 101. At this time, atomized matrix can be added to the liquid storage chamber 103.

[0042] In some application scenarios, the thrust passing through the liquid injection hole 101 can be provided by a liquid storage bottle inserted into the liquid injection hole 101, and the liquid storage bottle stores aerosolized matrix. When adding, the bottle mouth of the liquid storage bottle is inserted into the liquid injection hole 101, and the bottle mouth pushes the elastic part 201 to deflect the elastic part 201 away from the liquid injection hole 101. At this time, the aerosolized matrix in the liquid storage bottle will flow into the liquid storage cavity 103. In this embodiment, after the elastic part 201 is pushed and deflected, because the elastic part 201 is inclined away from the inner wall of the liquid storage cavity 103, only a small part of the rim of the bottle mouth of the liquid storage bottle presses against the elastic part 201 to prevent the elastic part 201 from rebounding, and the rest of the rim of the bottle mouth does not contact the elastic part 201, thereby forming a gap between the elastic part 201 and the bottle mouth for the aerosolized matrix to flow into the liquid storage cavity 103. After the aerosolized substrate is added, the bottle mouth of the liquid storage bottle is removed from the liquid injection hole 101. The elastic portion 201 is no longer subjected to force, and the elastic portion 201 will rebound and recover its deformation, automatically sealing and covering the liquid injection hole 101. In this embodiment, the distal end 204 of the elastic portion 201 is the end away from the fixed portion, but is not limited to the end. For example, the distal end 204 of the elastic portion 201 may include the portion between the end surface of the end away from the fixed portion 202 and the middle portion of the elastic portion 201.

[0043] One embodiment, such as Figure 3 、 Figure 4The elastic portion 201 includes opposing outer and inner side surfaces, both of which are curved to match the inner wall of the liquid storage chamber 103. The proximal end 205 of the elastic portion 201 is wider than the distal end 204. The proximal end 205 is the end of the elastic portion 201 closest to the fixed portion 202. The outer side surface is the side of the elastic portion 201 that contacts the inner wall of the liquid storage chamber 103. Both the outer and inner side surfaces are curved to provide a better contact with the inner wall of the liquid storage chamber 103. The proximal end 205 of the elastic portion 201 is wider than the distal end 204. The wider proximal end 205 ensures sufficient strength for the elastic portion 201, while the narrower distal end 204 ensures good elastic deformation capability for the elastic portion 201.

[0044] One embodiment, such as Figure 3 To enhance the strength of the elastic portion 201, a reinforcing rib 203 may be provided on the inner side of the elastic portion 201. One end of the reinforcing rib 203 is connected to the fixing portion 202, and the other end extends away from the fixing portion 202. The reinforcing rib 203 and the elastic portion 201 are integrally formed. The reinforcing rib 203 on the inner side provides support for the elastic portion 201, thereby enhancing the strength of the elastic portion 201. This not only stabilizes the fit between the elastic portion 201 and the inner wall of the liquid storage chamber 103, but also enhances the recovery of the elastic portion 201 after elastic deformation under the action of the reinforcing rib 203.

[0045] In one embodiment, the other end of the reinforcing rib 203 extends away from the fixed portion 202, and the highest point of the end surface of the extended end is higher than the lowest point of the wall surface of the liquid injection hole 101. In this case, the reinforcing rib 203 provides better support for the elastic portion 201, and the elastic portion 201 recovers better after elastic deformation under the action of the reinforcing rib 203. It is understood that the highest point and the lowest point in this embodiment are the highest point and the lowest point in the direction of extension of the reinforcing rib 203. If the other end surface of the reinforcing rib 203 is a plane, the highest point of the end surface can be any point on the plane; if the other end surface of the reinforcing rib 203 is a curved surface, the highest point of the end surface can be any point on a line. In some application scenarios, the extension direction of the reinforcing rib 203 and the extension direction of the cantilevered elastic portion 201 are both vertical. In this case, the highest point of the other end surface of the reinforcing rib 203 is the highest point of the upper end surface in the vertical direction, and the lowest point of the wall surface of the liquid injection hole 101 is the lowest point of the wall surface in the vertical direction.

[0046] The structure of the elastic portion 201 in this embodiment is not limited to the above embodiment, and can also be other elastic structures that can elastically deform to open the injection hole 101 and can restore the deformation to seal the injection hole 101. For example, in one embodiment, Figure 5The elastic portion 201 includes opposing inner and outer sides. The outer side is in contact with the inner wall of the liquid storage chamber 103. The inner side is an inclined surface. The thickness of the elastic portion 201 gradually decreases from the proximal end 205 to the distal end 204 of the elastic portion 201. The proximal end 205 is the end of the elastic portion 201 that is closest to the fixed portion 202. The inclined inner side of the elastic portion 201 creates a structure in which the proximal end 205 is thicker than the distal end 204. This structure also ensures a stable contact between the elastic portion 201 and the inner wall of the liquid storage chamber 103 and facilitates recovery of the elastic portion 201 after elastic deformation under the action of the reinforcing ribs 203.

[0047] One embodiment, such as Figure 6-Figure 8 The sealing element 2 has an assembled state and an unassembled state. The assembled state is a state in which the sealing element 2 is fixed in the housing 1, and the unassembled state is a state in which the sealing element 2 is not assembled in the housing 1. In the unassembled state, the elastic portion 201 forms a first angle α with the fixed portion 202, and in the assembled state, the elastic portion 201 forms a second angle β with the fixed portion 202. The first angle α is greater than the second angle β. For example, the first angle α is an obtuse angle greater than 90°, and the second angle β is a right angle or an acute angle. That is, when the sealing element 2 is assembled in the housing 1, the elastic portion 201 has undergone a certain elastic deformation. The deformed elastic portion 201 has a tendency to recover the elastic deformation. At this time, the elastic portion 201 can fit more tightly against the inner wall of the liquid storage chamber 103, so that the elastic portion 201 better seals the liquid injection hole 101. After the atomized matrix is ​​added, the elastic portion 201 recovers its deformation more quickly. In one embodiment, the elastic portion 201 in an unassembled state is in the shape of a cantilever that tilts outward. When assembled, the elastic portion 201 is squeezed by the housing 1 and deforms into a cantilever that is perpendicular to the fixed portion 202, thereby making the first angle greater than the second angle. During assembly, the outward-tilted elastic portion 201, squeezed by the housing 1, deflects toward the center of the liquid storage chamber 103. After this deflection, the angle between the elastic portion 201 and the fixed portion 202 decreases, i.e., the first angle is greater than the second angle. After this deflection, the elastic portion 201 fits more tightly against the inner wall of the liquid storage chamber 103, thereby providing a better seal between the elastic portion 201 and the liquid injection hole 101.

[0048] One embodiment, such as Figure 4 The elastic portion 201 is provided with an annular sealing rib 206, which fits the outer periphery of the liquid injection hole 101. The annular sealing rib 206 and the elastic portion 201 are integrally structured. The annular sealing rib 206 is pressed together by the force of the elastic portion 201 restoring its deformation, so that the annular sealing rib 206 fits tightly against the outer periphery of the liquid injection hole 101. The distal end 204 of the elastic portion 201 provides a better seal against the liquid injection hole 101. This embodiment does not impose any specific restrictions on the shape of the annular sealing rib 206. It can enclose the liquid injection hole 101 and can match or not match the shape of the liquid injection hole 101.

[0049] In one embodiment, the injection hole 101 can be a special-shaped hole. In this case, only a liquid storage bottle that matches the special-shaped hole can be used to add the atomized matrix. The special-shaped hole can better protect the product. The special-shaped hole in this embodiment is an uncommon hole. Common holes include circular holes, square holes, elliptical holes, and polygonal holes. Holes other than these common holes are special-shaped holes. For example, the shape of a special-shaped hole can be as follows: Figure 1 As shown, when the injection hole 101 is an irregular hole, the annular sealing rib 206 in this embodiment may also be an annular shape that is the same as or similar to the irregular hole; in some embodiments, when the injection hole 101 is an irregular hole, the annular sealing rib 206 may also be a common shape, such as a circular, square, elliptical, or polygonal ring; in some application scenarios, the injection hole 101 may also be the above-mentioned common hole.

[0050] One embodiment, such as Figure 3-Figure 5 The fixing portion 202 is provided with a mounting hole 207 that extends through the fixing portion 202. The inner wall of the mounting hole 207 is designed to seal against the outer periphery of the atomizer core. The fixing portion 202 also seals against the atomizer core, simplifying the sealing structure of the atomizer, increasing the integration of the atomizer structure and facilitating assembly. The electrical connection terminal of the atomizer core is exposed through the mounting hole 207, facilitating electrical connection of the atomizer core.

[0051] In one embodiment, the elastic portion 201 is provided with a boss, which is inserted into the injection hole 101, and the depth of the boss inserted into the injection hole 101 is less than the length of the injection hole 101. The boss and the elastic portion 201 can be an integral structure, and the boss fits into the injection hole 101. When an object applying external force to the elastic portion 201 has not yet been fully inserted into the injection hole 101, it can contact the boss and push the elastic portion 201, thereby reducing the insertion depth of the object and making it more convenient to add the atomized matrix. The depth of the boss inserted into the injection hole 101 is less than the length of the injection hole 101, thereby forming a step between the outer surface of the boss and the outer surface of the housing 1. The step can be used for positioning the object when it is inserted, avoiding the situation where the object is not aligned with the injection hole 101 during insertion.

[0052] The atomizer in this embodiment is not limited to including the structures and components of the above-mentioned embodiment, but may also include other structures and components required for atomization, such as an atomizer core, liquid storage cotton, etc.

[0053] In the atomizer of the present embodiment, a sealing element 2 is provided inside the housing 1, and the sealing element 2 blocks the injection hole 101 by the elastic part 201. When adding atomized substrate, a thrust is applied to the elastic part 201 through the injection hole 101, so that the elastic part 201 undergoes elastic deformation and leaves the injection hole 101 to open the injection hole 101. The added atomized substrate can be added to the liquid storage chamber 103 through the injection hole 101. After adding, the thrust applied is removed, and the elastic part 201 will automatically rebound and recover the deformation. After the elastic part 201 rebounds, it is restored to the state of blocking the injection hole 101. The automatic rebound of the elastic part 201 is fast and reliable, solves the problem of poor sealing and liquid leakage caused by improper user operation, improves the sealing stability and effectiveness of the atomizing device, avoids the leakage of the atomized substrate, and the addition of the atomized substrate is also simple and fast.

[0054] Please refer to Figure 9 In one embodiment, an atomization device is provided, comprising: a power supply component, and the atomizer as described above, the atomizer comprising an atomization component, and the atomization component is electrically connected to the power supply component.

[0055] The atomization assembly in this embodiment includes a liquid storage cotton and an atomization core. The liquid storage cotton is used to absorb the atomization matrix in the liquid storage chamber 103 for heating and atomization by the atomization core. The atomization core is powered by the power supply component to generate heat, and the atomization matrix is ​​heated and atomized into an aerosol that can be inhaled by the user. This embodiment does not specifically limit the power supply component, for example, it may include but is not limited to a power supply, a circuit board, etc. The atomization device of this embodiment may also include other functional components, which can be configured as needed. The atomizer in this embodiment is the same as the above embodiment and will not be described in detail here.

[0056] The atomizing device in the present embodiment includes an atomizer, and the inside of the atomizer housing 1 is provided with a sealing element 2, and the sealing element 2 is through the plugging injection hole 101 of the elastic part 201. When adding atomized substrate, a thrust effect is applied to the elastic part 201 through the injection hole 101, so that the elastic part 201 is elastically deformed and leaves the injection hole 101 to open the injection hole 101, and the added atomized substrate can be added to the liquid storage chamber 103 through the injection hole 101. After adding, the thrust effect applied is removed, and the elastic part 201 will automatically rebound and recover the deformation, and the elastic part 201 will return to the state of plugging the injection hole 101 after the rebound. The automatic rebound of the elastic part 201 is fast and reliable, solves the problem of poor sealing and liquid leakage caused by improper user operation, improves the sealing stability and effectiveness of the atomizing device, avoids the leakage of the atomized substrate, and the addition of the atomized substrate is also simple and fast.
