Description

Technical Field

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

[0002] An aerosol is a colloidal dispersion system formed by solid or liquid small particles dispersed and suspended in a gas medium. Since aerosols can be absorbed by the human body through the respiratory system, it provides users with a new alternative absorption method. An atomizer refers to a device that forms an aerosol by heating or ultrasonic means on the stored atomizable medium. The atomization medium includes liquid, gel, paste or solid aerosol generation matrix. Atomizing these media can deliver inhalable aerosols to users, replacing the conventional product form and absorption method.

[0003] An atomizer using a puncture-type liquid storage component usually includes a liquid storage component and a puncture structure. The liquid storage component is used to store the atomization medium, and the puncture structure is used to puncture the liquid storage component to allow the atomization medium to flow out. However, due to structural defects, the existing atomizers using puncture-type liquid storage components are difficult to effectively prevent the leakage of the atomization medium while ensuring the smoothness of plugging and unplugging, thus affecting the user experience and being unfavorable for the further promotion and application of such atomizers. Summary of the Utility Model

[0004] Based on this, in view of the problem of difficult plugging and unplugging between the liquid storage component and the puncture structure, it is necessary to provide an atomizer and an electronic atomization device.

[0005] An atomizer, comprising:

[0006] A liquid storage component, including a housing and a sealing cover provided at one end of the housing, a liquid storage cavity is formed between the housing and the sealing cover; and

[0007] A heating component, connected to the end of the liquid storage component provided with the sealing cover, the heating component includes a puncturing member, and the puncturing member is used to puncture the sealing cover to form a fluid connection between the liquid storage cavity and the heating component;

[0008] Wherein, there is a gap between the outer edge of the puncturing member and the outer edge of the sealing cover, and the sealing cover further has a sealing structure, and the sealing structure seals the gap between the sealing cover and the puncturing member.

[0009] In one embodiment, the sealing structure has a height difference from the punctured plane of the sealing cover, and the sealing structure is located on the side of the punctured plane away from the liquid storage cavity.

[0010] In one embodiment, the sealing cap has a communicating channel through which the piercing element extends into the liquid storage chamber; the communicating channel has an inner sidewall, and a gap is formed between the outer wall of the piercing element and the inner sidewall of the communicating channel.

[0011] In one embodiment, the sealing structure extends circumferentially along the inner sidewall of the communication channel to surround the puncture member.

[0012] In one embodiment, the sealing structure forms a guide surface on the side facing away from the liquid storage cavity;

[0013] Along the insertion direction of the puncturing member, the guide surface extends obliquely toward the liquid storage cavity from one edge of the inner wall connecting the communicating channel to one edge of the inner wall away from the communicating channel.

[0014] In one embodiment, the puncturing element punctures the sealing cap and forms a liquid channel within the puncturing element to create fluid communication between the liquid storage chamber and the heating element.

[0015] In one embodiment, the channel wall of the liquid discharge channel is provided with at least one liquid guiding groove, the at least one liquid guiding groove is arranged at intervals along the circumference, and each liquid guiding groove extends along the length direction of the liquid discharge channel.

[0016] In one embodiment, the end of the puncturing member inserted into the liquid storage cavity has a protruding puncture portion that extends into the liquid channel.

[0017] In one embodiment, one end of the puncturing member inserted into the liquid storage cavity forms a puncturing surface that extends obliquely relative to the insertion direction of the puncturing member, and the puncturing portion is connected to the area of ​​the puncturing surface closest to the sealing cap.

[0018] An electronic atomizing device includes the aforementioned atomizer, and the electronic atomizing device further includes a power supply component for supplying power to the atomizer.

[0019] In the aforementioned atomizer, because the outer diameter of the piercing element is smaller than the outer diameter of the pierced structure, the friction between the piercing element and the sealing cap is minimal after the piercing element pierces the structure. This allows users to easily separate the liquid reservoir assembly from the heating assembly for replacement, effectively improving the user experience. Furthermore, since the gap between the sealing cap and the piercing element is sealed by a sealing structure, it effectively prevents the atomizing medium in the liquid reservoir from flowing out between the sealing cap and the piercing element. This facilitates easy insertion and removal of the liquid reservoir assembly while preventing atomizing medium leakage, thus improving the reliability of the atomizer. Attached Figure Description

[0039] See Figure 1 This application provides an electronic atomizing device 1000 for atomizing a medium to generate an aerosol for user use. The atomizing medium includes, but is not limited to, liquid materials such as medicines and oils used for medical, health, or beauty purposes. The atomization method includes, but is not limited to, resistance heating, electromagnetic heating, infrared heating, laser heating, or microwave heating.

[0040] In the following embodiments, the height direction of the electronic atomizing device 1000 is defined as the first direction (i.e., Figure 1 The Z-direction in the middle), the length direction of the electronic atomizing device 1000 is the second direction (i.e., Figure 1 In the X direction), the first direction intersects with the second direction. In a preferred embodiment, the first direction and the second direction are perpendicular to each other.

[0041] The electronic atomizing device 1000 includes an atomizer 100 and a power supply component 200. The power supply component 200 is connected to one end of the atomizer 100 in a first direction and is electrically connected to the atomizer 100. The atomizer 100 is used to store the atomizing medium and heats and atomizes the atomizing medium under the action of the electrical energy of the power supply component 200.

[0042] like Figure 2 and Figure 3 As shown, the atomizer 100 includes a liquid reservoir 120 and a heating element 140. The liquid reservoir 120 stores the atomizing medium. The heating element 140 can be connected to one end of the liquid reservoir 120 and puncture the liquid reservoir 120, allowing the atomizing medium in the liquid reservoir 120 to flow into the heating element 140, where it is heated and atomized to generate an aerosol. In the following embodiments, the heating element 140 and the liquid reservoir 120 are detachably connected. After the atomizing medium in the liquid reservoir 120 is completely consumed, the user can replace the liquid reservoir 120 with a new one, while the heating element 140 can be reused.

[0043] The liquid storage assembly 120 includes a housing 121 and a sealing cap 123 disposed at one end of the housing 121. A liquid storage chamber 120a for storing atomizing medium is formed between the housing 121 and the sealing cap 123. The heating assembly 140 is coupled to the end of the liquid storage assembly 120 where the sealing cap 123 is located. The heating assembly 140 includes a puncture member 141 for puncturing the sealing cap 123 to form fluid communication between the liquid storage chamber 120a and the heating assembly 140, so that the atomizing medium in the liquid storage chamber 120a can flow into the heating assembly 140.

[0044] Please see Figure 2 When the liquid storage assembly 120 is not connected to the heating assembly 140, the sealing cap 123 can seal the outer casing 121, thereby preventing leakage of the atomized medium in the liquid storage chamber 120a. Please refer to... Figure 3 When the liquid storage component 120 and the heating component 140 are connected to each other, the piercing part 141 of the heating component 140 can pierce the sealing cover 123, and the atomizing medium in the liquid storage chamber 120a can enter the liquid storage chamber 120a to supply liquid to the heating component 140.

[0045] As described in the background section, the liquid storage component 120 and the heating component 140 are typically connected to each other by an interference fit to prevent the atomizing medium in the liquid storage chamber 120a from leaking through the gap between them. However, this also results in a large frictional force between the liquid storage component 120 and the heating component 140, which makes it inconvenient to disassemble and assemble the liquid storage component 120 and the heating component 140, and easily leads to leakage of the atomizing medium during disassembly, thus affecting the user's experience.

[0046] To solve the above technical problems, please combine Figures 2 to 5 As shown, there is a gap h between the outer edge of the puncture member 141 and the outer edge of the sealing cover 123 in this application. The sealing cover 123 also has a sealing structure 1245, which is used to close the gap between the sealing cover 123 and the puncture member 141.

[0047] Thus, because there is a gap h between the outer edge of the puncture member 141 and the outer edge of the sealing cap 123, when the puncture member 141 punctures the sealing cap 123, the outer edge of the puncture member 141 and the outer edge of the sealing cap 123 are in a gap fit with each other, resulting in low friction. This allows the user to easily separate the liquid storage assembly 120 from the heating assembly 140 for replacement, effectively improving the user experience. Furthermore, because the gap h between the sealing cap 123 and the puncture member 141 is sealed by the sealing structure 1245, it effectively prevents the atomizing medium in the liquid storage chamber 120a from flowing out through the gap h. This allows for easy insertion and removal of the liquid storage assembly 120 while preventing leakage of the atomizing medium, improving the reliability of the atomizer 100.

[0048] Furthermore, in some embodiments, the sealing cap 123 has a communicating channel 123a, through which the piercing element 141 extends into the liquid storage chamber 120a. The communicating channel 123a has an inner sidewall, and a gap h is formed between the outer wall of the piercing element 141 and the inner sidewall of the communicating channel 123a.

[0049] Thus, when the liquid storage component 120 is not connected to the heating component 140, the connecting channel 123a is in a closed state. When the liquid storage component 120 and the heating component 140 are connected to each other, the puncturing element 141 passes through the connecting channel 123a to extend into the liquid storage chamber 120a, and the sealing structure 1245 closes the gap h to prevent leakage of the atomizing medium.

[0050] In some embodiments, the sealing structure 1245 and the punctured plane of the sealing cover 123 have a height difference in a first direction. The sealing structure 1245 is located on the side of the punctured plane away from the liquid storage chamber 120a, thereby serving to receive the atomizing medium that may leak from the gap h and effectively preventing the atomizing medium from leaking out of the atomizer 100.

[0051] In some embodiments, such as Figure 2As shown, the outer casing 121 includes a main casing 1212 and an exhaust pipe 1214. The main casing 1212 has a hollow shell structure and has an open end and a closed end arranged opposite to each other in a first direction. One end of the exhaust pipe 1214 is connected to the closed end of the main casing 1212, and the other end of the exhaust pipe 1214 extends towards the open end of the main casing 1212 along the first direction. An exhaust channel 1214a is formed inside the exhaust pipe 1214, and the exhaust channel 1214a passes through the closed end of the exhaust pipe 1214 to communicate with the external atmosphere. A liquid storage chamber 120a surrounds the exhaust pipe 1214 circumferentially.

[0052] Please see Figure 2 , Figure 3 , Figure 6 , Figure 8 as well as Figure 9 The sealing cover 123 includes a cover body 122 and a sealing element 124 embedded in the cover body 122.

[0053] The cover body 122 includes a first cover 1221 and a second cover 1223. The shape of the first cover 1221 matches the shape of the opening end of the main housing 1212 so as to be fitted into the opening end of the main housing 1212. The second cover 1223 is connected to the center position of one side of the first cover 1221 and protrudes out of the main housing 1212, and the outer diameter of the second cover 1223 is smaller than the outer diameter of the first cover 1221.

[0054] The cover body 122 has an atomizing channel 122a and two connecting holes 122b. The atomizing channel 122a is formed at the center of the sealing cover 123 and extends through the first cover body 1221 and the second cover body 1223 along a first direction. One end of the exhaust pipe 1214 of the outer shell 121 is inserted into the atomizing channel 122a located in the first cover body 1221 along the first direction, thereby enabling the exhaust channel 1214a and the atomizing channel 122a to communicate with each other. The two connecting holes 122b are formed in the first cover body 1221 and are located on opposite sides of the atomizing channel 122a in a second direction. It can be understood that in some other embodiments, the number and location of the connecting holes 122b are not limited to this. In one embodiment, the sealing cover 123 may have only one connecting hole 122b.

[0055] The seal 124 is formed of a flexible material such as silicone and includes an interconnected and integrally formed sealing body 1241, a punctured structure 1243, and a sealing structure 1245.

[0056] Specifically, the sealing body 1241 includes a first sealing part 1241a, a second sealing part 1241b, and a third sealing part 1243. The first sealing part 1241a covers the inner wall of the atomizing channel 122a located in the first cover 1221 circumferentially, the second sealing part 1241b covers the outer wall of the second cover 1223 circumferentially, the third sealing part 1241c is located in the connecting hole 122b, the third sealing part 1241c surrounds the middle region of the hole wall of the connecting hole 122b circumferentially, the third sealing part 1241c and the connecting hole 122b together define a connecting channel 123a, and the inner wall of the third sealing part 1241c and the hole wall of the connecting hole 122b not covered by the third sealing part 1241c together form the inner wall of the connecting channel 123a.

[0057] The punctured structure 1243 is located at one end of the third sealing portion 1241c near the liquid storage chamber 120a. The punctured structure 1243 completely covers the opening end of the third sealing portion 1241c, thereby sealing the communication channel 123a. When the liquid storage assembly 120 is not mated with the heating assembly 140, the punctured structure 1243 seals the communication channel 123a, thereby keeping the liquid storage chamber 120a in a sealed state to prevent leakage of the atomized medium. When the puncturing element 141 punctures the punctured structure 1243, at least a portion of the edge of the punctured structure 1243 detaches from the third sealing portion 1241c, thereby opening the communication channel 123a. The outer edge of the punctured structure 1243 is the outer edge of the aforementioned sealing cover 123. As a preferred real-time method, the thickness of a portion of the edge of the punctured structure 1243 is less than the thickness of other areas of the punctured structure, thereby having lower strength to facilitate puncture by the puncturing element 141.

[0058] A sealing structure 1245 is formed within the end of the third sealing portion 1241c away from the punctured structure 1243. The sealing structure 1245 extends circumferentially along the inner wall of the third sealing portion 1241c to surround the punctured member 141, thereby sealing the gap h between the punctured member 141 and the inner wall of the communicating channel 123a. Thus, the sealing structure 1235 forms an annular sealing ring around the inner wall of the communicating channel 123a. The sealing structure 1235 is interference-fitted with the punctured member 141, thereby sealing all areas around the punctured member 141 and ensuring that the atomized medium in the liquid storage chamber 120a cannot leak through the gap h. Since the sealing cap 123 only contacts the punctured member 141 through the sealing structure 1235, the contact area between them is small, so excessive friction will not be generated, affecting the smoothness of disassembly and assembly of the liquid storage assembly 120 and the heating assembly 140. In other embodiments, the shape of the sealing structure 1235 can be set as needed to meet different sealing requirements.

[0059] As a preferred implementation method, such as Figure 4As shown, the sealing structure 1235 forms a guide surface 1245a on the side facing away from the liquid storage cavity 120a. Along the insertion direction of the piercing member 141, the guide surface 1245a extends obliquely towards the liquid storage cavity 120a from one edge of the inner wall of the connecting channel 123a to the other edge away from the inner wall of the connecting channel 123a, forming a conical surface. The guide surface 1245a guides the piercing member 141 to pierce the pierced structure 1243, allowing the piercing member 141 to smoothly pierce the pierced structure 1243 and enter the liquid storage cavity 120a. It can be understood that the shape of the guide surface 1245a is not limited to this and can be configured as needed to meet different requirements.

[0060] It is understood that the number of sealing structures 1235 is not limited. In some embodiments, the sealing cover 123 has only one annular sealing structure 1235. In other embodiments, the sealing cover 123 may also include multiple sealing structures 1235, all of which are arranged axially at intervals along the inner sidewall of the communicating channel 123a, thereby forming multiple seals to improve the sealing effect.

[0061] like Figure 2 , Figure 5 , Figure 6 as well as Figure 7 As shown, the heating assembly 140 includes a puncture component 141, a heating top cover 143, a heating base 145, and an atomizing core 147.

[0062] The heating base 145 is fitted to one end of the heating top cover 143 in the first direction, and the heating top cover 143 and the heating base 145 together define an atomizing chamber 140a with openings at both ends in the first direction. Two piercing elements 141 protrude from the other end of the heating top cover 143 in the first direction, and the two piercing elements 141 are spaced apart in the second direction. It can be understood that the number of piercing elements 141 corresponds to the number of connecting channels 123a. When the sealing cover 123 has only one connecting channel 123a, the heating assembly 140 also has only one corresponding piercing element 141.

[0063] The atomizing core 147 is housed in the atomizing chamber 140a and includes a substrate and a heating element embedded in the surface of the substrate. The substrate absorbs the atomizing medium and guides it to the heating element, which heats the atomizing medium to generate an aerosol. It is understood that the specific location of the heating element is not limited; it can be located on the upper surface of the substrate facing away from the heating base 145, on the lower surface of the substrate facing the heating base 145, or on the side surface of the substrate.

[0064] When the heating element 140 and the liquid storage element 120 are mated together, the sealing cap 123 and the heating top cap 143 abut against each other in the first direction. The second cover body 1223 of the sealing cap 123 extends into the heating top cap 143 in the first direction. The atomizing channel 122a on the sealing cap 123 is connected to the atomizing chamber 140a of the heating element 140. Therefore, the aerosol flowing out from the atomizing chamber 140a can flow out sequentially through the atomizing channel 122a and the exhaust channel 1214a. The two piercing elements 141 pierce the pierced structure 1243 in the first direction and insert into the liquid storage chamber 120a.

[0065] Since the outer diameter of the puncturing element 141 is smaller than the outer diameter of the punctured structure 1243, after the puncturing element 141 is punctured by the puncturing structure 1243, a circumferential gap h is formed between the inner wall of the connecting channel 123a and the puncturing element 141. This significantly reduces the friction between the inner wall of the connecting channel 123a and the puncturing element 141 during the assembly and disassembly of the heating element 140 and the liquid storage component 120, making the assembly and disassembly of the heating element 140 and the liquid storage component 120 smoother. In some other embodiments, the inner wall of the connecting channel 123a may also partially contact the puncturing element 141, thereby reducing the friction between them while still maintaining a certain sealing effect.

[0066] In some embodiments, each puncture member 141 is a hollow tubular structure, thereby forming a liquid discharge channel 100a extending along a first direction. The liquid discharge channel 100a serves to establish fluid communication between the liquid storage chamber 120a and the heating element 140, so that the atomizing medium in the liquid storage chamber 120a can enter the atomizing chamber 140a through the liquid discharge channel 100a. It is understood that the formation of the liquid discharge channel 100a is not limited to this. In other embodiments, the puncture member 141 may also be a solid structure. When the puncture member punctures the punctured structure 1243, the sealing cap 123 forms the liquid discharge channel 100a.

[0067] In some embodiments, such as Figure 7 As shown, the channel walls of the liquid channels 100a of the two puncture parts 141 are provided with liquid guiding grooves 141b. The liquid guiding grooves 141b can form a capillary effect, guiding the atomizing medium in the liquid storage chamber 120a to quickly pass through the narrow space of the liquid channel 100a and reach the atomizing chamber 140a, effectively preventing the occurrence of insufficient liquid supply.

[0068] In one specific embodiment, the channel wall of the liquid discharge channel 100a is provided with at least one liquid guiding groove 141b. The at least one liquid guiding groove 141b is arranged at intervals along the circumference, and each liquid guiding groove 141b extends along the length of the liquid discharge channel 100a, thereby forming a good liquid guiding effect. It is understood that the number, shape, and arrangement of the liquid guiding grooves 141b are not limited, and can be set as needed to meet the liquid discharge requirements.

[0069] Furthermore, when the liquid atomized medium reaches the end of the piercing member 141 inserted into the liquid storage cavity 120a, the friction between the atomized medium and the piercing member 141 will form a liquid film that blocks the liquid discharge channel 100a, resulting in a liquid seal and preventing normal liquid discharge. To address the above problem, in some embodiments, the end of the piercing member 141 inserted into the liquid storage cavity 120a is provided with a piercing portion 1412 extending into the liquid discharge channel 100a. The piercing portion 1412 is used to pierce the liquid film formed by the atomized medium, thereby preventing a liquid seal and allowing the liquid to smoothly enter the liquid discharge channel 100a. It is understood that the shape and number of the piercing portions 1412 are not limited and can be set as needed to achieve a good piercing effect.

[0070] In a preferred embodiment, the end of the piercing member 141 inserted into the liquid storage cavity 120a extends obliquely, thereby forming a piercing surface that extends obliquely relative to the insertion direction of the piercing member 141 to facilitate piercing the pierced structure 1243. The piercing portion 1412 is connected to the area of ​​the piercing surface closest to the sealing cap 123 (i.e., the lowest point of the piercing surface), thereby achieving a better piercing effect. It is understood that the position of the piercing portion 1412 is not limited to this and can also be located at other positions on the piercing surface.

[0071] The aforementioned atomizer 100 and electronic atomizing device 1000, by providing a gap h between the outer edge of the puncture member 141 and the outer edge of the sealing cap 123, can avoid excessive friction caused by the interference fit between the puncture member 141 and the sealing cap 123, making it easier to insert and remove the liquid storage component 120 and the heating component 140. Simultaneously, the sealing structure 1235, while ensuring smoother insertion and removal, also prevents leakage of the atomizing medium through the gap h. Furthermore, improvements to the puncture member 141 ensure smoother liquid flow of the atomizing medium, effectively preventing dry burning due to insufficient liquid supply to the atomizing core 147.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
