Electronic atomizer and liquid guiding connection structure thereof

Abstract

This utility model relates to the field of electronic atomization technology, specifically disclosing an electronic atomizer and its liquid guiding connection structure. The liquid guiding connection structure includes a tubular body with a first puncture portion and a second puncture portion. The first puncture portion has a greater radial inclination relative to the tubular body than the second puncture portion, and the first puncture portion is located at the end of the tubular body, while the second puncture portion is located in the middle of the tubular body. Because the first and second puncture portions have different inclinations, the first puncture portion, with its greater inclination, can be used to puncture and break the sealing membrane at the liquid outlet of the reservoir, while the second puncture portion, with its smaller inclination, has a wider lateral volume, which can expand the sealing membrane to form a larger liquid outlet cross-section, ensuring successful liquid outlet from the reservoir and guaranteeing the liquid flow rate. This electronic atomizer has fewer liquid guiding connection structures, reducing its space occupation and manufacturing costs.

Description

Technical Field

[0001] This utility model relates to the field of electronic atomization technology, specifically to an electronic atomizer and its liquid guiding connection structure. Background Technology

[0002] In electronic atomizers, to increase the capacity of the liquid atomizing matrix and extend the atomizer's lifespan, or to incorporate multiple detachable components, the reservoir and atomizer are designed as separate structures. Users must manually connect the reservoir and atomizer to allow the liquid matrix from the reservoir to enter the atomizer.

[0003] Existing electronic atomizers primarily connect the liquid reservoir and the atomizer in two ways: one is by pushing open the silicone plug; a silicone plug is installed in the liquid outlet of the liquid reservoir, and after the two are connected, the atomizer pushes the silicone plug into the liquid reservoir and opens the liquid outlet to connect the liquid reservoir and the atomization chamber. In this structure, the silicone plug may leak during transportation. The other is by piercing the membrane; a membrane structure is installed in the liquid outlet of the liquid reservoir, and after the two are connected, the atomizer pierces the membrane structure to open the liquid outlet to connect the liquid reservoir and the atomization chamber. In this structure, multiple piercing structures are required to achieve liquid dispensing, which takes up a lot of space, increasing the complexity and cost of the equipment. Utility Model Content

[0004] This invention provides an electronic atomizer and its liquid guiding connection structure to solve the problems of large space occupation by the puncture structure and increased complexity and cost of the equipment.

[0005] In one embodiment, a liquid guiding connection structure for an electronic atomizer is provided, including a tubular body. The tubular body is provided with a first puncture portion and a second puncture portion. The first puncture portion and the second puncture portion are used to puncture the sealing membrane at the liquid outlet of the liquid storage chamber. The radial inclination of the first puncture portion relative to the tubular body is greater than the radial inclination of the second puncture portion relative to the tubular body. The first puncture portion is located at the end of the tubular body, and the second puncture portion is located at the middle of the tubular body.

[0006] In one embodiment, the first puncture portion is a sharp structure formed by the tubular body extending along the axial direction.

[0007] In one embodiment, the second puncture site is located within the cavity of the tubular body.

[0008] In one embodiment, the second puncture portion extends into the cavity of the tubular body, dividing the cavity of the tubular body into a first through hole and a second through hole.

[0009] In one embodiment, the cross-sectional area of ​​the first through hole is larger than that of the second through hole, the first through hole is used for guiding liquid, and the second through hole is used for guiding gas.

[0010] In one embodiment, the second puncture portion is an arc-shaped structure.

[0011] In one embodiment, the tubular body is provided with an installation portion located at one end of the tubular body away from the first puncture portion. The installation portion protrudes radially outward from the tubular body and is used to engage with the outlet of the liquid storage chamber.

[0012] In one embodiment, an electronic atomizer is provided, including a liquid reservoir, an atomizing core, and the liquid guiding connection structure described above; The liquid storage tank has a liquid outlet, and the liquid outlet is provided with a sealing membrane to seal the liquid outlet; The atomizing core has a liquid inlet, and the liquid inlet is provided with the liquid guiding connection structure.

[0013] In one embodiment, the sealing membrane includes a central region and a puncture region surrounding the central region, the thickness of the puncture region being less than the thickness of the central region.

[0014] In one embodiment, the outlet is further provided with a sealing part, which is used to engage with the tubular body and form a sealed connection.

[0015] According to the above embodiment of the electronic atomizer and its liquid guiding connection structure, since the liquid guiding connection structure is provided with a first puncture part and a second puncture part, the first puncture part and the second puncture part have different inclinations. The first puncture part with a larger inclination can be used to puncture and break the sealing membrane at the liquid outlet of the storage tank, and the second puncture part with a smaller inclination has a wide lateral volume, which can expand the sealing membrane to form a larger liquid outlet cross section, thus ensuring successful liquid outlet from the storage tank and ensuring the liquid flow rate. This replaces the traditional electronic atomizer that uses multiple liquid guiding connection structures to form multiple liquid outlets to increase the liquid flow rate. The electronic atomizer has fewer liquid guiding connection structures, which can reduce its space occupation and reduce manufacturing costs. Attached Figure Description

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. 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.

[0018] 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.

[0019] 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).

[0020] In one embodiment, an electronic atomizer is provided. This electronic atomizer is used to heat a liquid atomizing matrix to form an atomized gas for inhalation by a user. The electronic atomizer has a removable liquid reservoir. When using the electronic atomizer, the user needs to install the liquid reservoir onto the electronic atomizer body. During installation, the liquid guiding connection structure on the electronic atomizer body punctures the sealing membrane at the liquid outlet of the liquid reservoir, allowing the liquid reservoir to communicate with the atomizing core. The liquid atomizing matrix in the liquid reservoir can then flow into the atomizing core, achieving heating and atomization.

[0021] The liquid-conducting connection structure is equipped with two puncture structures with different inclinations. One of the puncture structures is sharper and used to puncture the sealing membrane of the liquid storage tank, while the other is blunter and used to open the sealing membrane. This allows a single liquid-conducting connection structure to simultaneously puncture and open the sealing membrane, forming a larger opening and ensuring sufficient liquid inflow.

[0022] Please refer to Figures 1 to 6 The electronic atomizer of this application mainly includes a shell 1, an atomizing core 2, a liquid storage tank 3 and a liquid guiding connection structure 4. The electronic atomizer may also include a circuit board, a battery, a microphone and other necessary components to enable the electronic atomizer to work normally, as well as components such as a support structure inside the shell 1.

[0023] The outer casing 1 can be assembled from multiple casing structures. For example, the outer casing 1 mainly includes an upper casing 11 and a lower casing 12, which are connected by magnetic attraction or detachable snap-fit. This arrangement allows components such as the liquid storage tank 3 to be installed inside the outer casing 1.

[0024] In other embodiments, the outer shell 1 can also be a detachable structure, for example, the upper shell 11 and the lower shell 12 can be fixedly connected by snap-fitting, adhesive or other means. This configuration allows for operations such as replacing the atomizer coil 2 and installing the e-liquid pack, enabling maintenance and reuse of the e-atomizer.

[0025] In this embodiment, the first end of the upper shell 11 is provided with a suction nozzle 111. The suction nozzle 111 can be an integral structure with the upper shell 11, or the suction nozzle 111 can be fixed on the upper shell 11 by installation.

[0026] The liquid reservoir 3 is detachably installed inside the upper shell 11, and can be fixed to the upper shell 11 by means of snap-fit ​​or other methods. The liquid reservoir 3 is designed as a detachable structure, allowing the e-atomizer to be refilled to extend its usage time. In other embodiments, the liquid reservoir 3 can also be configured as a fixed installation component with the upper shell 11, for example, the upper shell 11 and the liquid reservoir 3 are an integrated structure; with this configuration, the e-atomizer is a disposable product, which can meet the usage needs of some consumers.

[0027] In this embodiment, the atomizing core 2 is installed inside the lower shell 12, and part of the atomizing core 2 is inserted into the upper shell 11 and docks with the mouthpiece 111 so that the mouthpiece 111 and the air passage of the atomizing core 2 are connected.

[0028] The atomizing core 2 mainly includes an atomizing tube 21, a liquid storage matrix 22, and a heating element 23. The atomizing tube 21 is connected to the mouthpiece 111. The liquid storage matrix 22 and the heating element 23 are installed inside the atomizing tube 21. The atomizing tube 21 has a liquid inlet. The liquid storage matrix 22 is used to adsorb and store the liquid atomizing matrix. The heating element 23 is electrically connected to the circuit board. The heating element 23 is used to heat the liquid atomizing matrix in the liquid storage matrix 22 to form inhalable smoke.

[0029] The atomizing core 2 can also atomize the housing 24, and the atomizing core 2 is located inside the atomizing housing 24. The liquid guiding connection structure 4 is located on the atomizing housing 24. The liquid guiding connection structure 4 can be an integral structure with the atomizing housing 24, or it can be fixed to the atomizing housing 24 by snap-fit ​​or other means. The liquid guiding connection structure 4 protrudes from the lower shell 12 so that it can be inserted into the liquid storage chamber 3 located in the upper shell 11.

[0030] The atomizing housing 24 also has a liquid guiding channel 241. One end of the liquid guiding channel 241 is connected to the liquid guiding connection structure 4, and the other end of the liquid guiding channel 241 is connected to the atomizing core 2, so that the liquid atomizing matrix can enter the atomizing core 2 from the liquid guiding connection structure 4 and the liquid guiding channel 241. The liquid guiding channel 241 can be formed by the atomizing housing 24 alone, or it can be formed by the atomizing housing 24 being enclosed by other components such as silicone structures.

[0031] In this embodiment, the lower end of the liquid storage tank 3 is provided with a liquid outlet 31, and a sealing membrane 32 is provided at the liquid outlet 31. The sealing membrane 32 can be formed by a structural component made of materials such as silicone. The sealing membrane 32 has a thinner thickness than other areas of the silicone structural component, so that the sealing membrane 32 can be punctured.

[0032] In the vertical direction of the electronic atomizer (the end with the mouthpiece 111 is the upper end), the liquid outlet 31 is aligned with the liquid guiding connection structure 4. After the upper shell 11 and the lower shell 12 are installed vertically aligned, the liquid guiding connection structure 4 is inserted into the liquid outlet 31 and punctures the sealing film 32 so that the liquid guiding channel 241 is connected to the liquid storage tank 3.

[0033] The liquid-conducting connection structure 4 includes a tubular body 41, which has a first puncture portion 411 and a second puncture portion 412. The first puncture portion 411 is located at the end of the tubular body 41 and has a sharp structure. The second puncture portion 412 is located in the middle of the tubular body 41 and has a more blunt puncture structure. The radial inclination of the first puncture portion 411 relative to the tubular body 41 is greater than that of the second puncture portion 412 relative to the tubular body 41. The end of the first puncture portion 411 is smaller and narrower, making it easier to puncture the sealing membrane 32. The second puncture portion 412 forms a radially wider inclined knife-shaped structure. The second puncture portion 412 is used to open the sealing membrane 32 to open a larger diameter of the liquid outlet 31, thereby achieving a larger liquid inlet flow rate to meet the liquid inlet requirements of the atomizing core 2.

[0034] The first puncture portion 411 can be formed by extending the tubular body 41 axially, that is, the first puncture portion 411 and the tubular body 41 form an integrated structure, which is convenient for manufacturing. The second puncture portion 412 can be located in the cavity of the tubular body 41. The second puncture portion 412 and the first puncture portion 411 can form an intersecting structure on the radial cross-section of the tubular body 41. This structure forms a puncture structure similar to a T-shaped cross-section, which can improve the structural strength of the puncture structure, making it less prone to deformation. It can ensure that the puncture structure can puncture the sealing membrane 32, and can easily push open a larger area of ​​the punctured sealing membrane 32 to open a larger diameter of the liquid outlet 31.

[0035] In this embodiment, since the liquid guiding connection structure 4 is provided with a first puncture part 411 and a second puncture part 412, the first puncture part 411 and the second puncture part 412 have different inclinations. The first puncture part 411 with a larger inclination can be used to puncture and break the sealing membrane 32 at the liquid outlet 31 of the liquid storage chamber 3. The second puncture part 412 with a smaller inclination has a wide lateral volume, which can expand the sealing membrane 32 to form a larger liquid outlet cross section, which can ensure the successful liquid outlet of the liquid storage chamber and ensure the liquid flow rate. This replaces the solution of using multiple liquid guiding connection structures to form multiple liquid outlets to increase the liquid flow rate in traditional electronic atomizers. This electronic atomizer can achieve this with a single liquid guiding connection structure 4. The number of liquid guiding connection structures 4 is small, which can reduce their space occupation and reduce manufacturing costs.

[0036] Furthermore, the arrangement of the first puncture part 411 and the second puncture part 412 will not puncture the sealing membrane 32. The sealing membrane 32 will be opened in the manner of opening a door, and the sealing membrane 32 will still be connected to the silicone at the liquid outlet 31. The sealing membrane 32 will not detach and enter the liquid storage chamber of the liquid storage tank 3, which can prevent the sealing membrane 32 from blocking the liquid outlet 31 again. The sealing membrane 32 floats in the liquid storage tank 3.

[0037] In this embodiment, the inner diameter of the tubular body 41 of the fluid guiding connection structure 4 can be greater than 2mm to ensure sufficient space for fluid insertion and space for setting the second puncture part 412.

[0038] Please refer to Figure 3 , Figure 5 and Figure 6 In one embodiment, the second puncture portion 412 extends into the tubular body 41, from one end to the other. The second puncture portion 412 divides the inner cavity of the tubular body 41 into a first through-hole 413 and a second through-hole 414, with the two through-holes being of different sizes. The radial cross-sectional area of ​​the first through-hole 413 is larger than that of the second through-hole 414. This configuration allows the larger first through-hole 413 to be used for liquid guidance, while the smaller second through-hole 414 can be used for gas guidance, enabling simultaneous liquid drainage and air intake from the liquid storage chamber 3, achieving gas-liquid circulation, and ensuring that the liquid atomizing matrix within the liquid storage chamber 3 can flow smoothly into the atomizing core 2.

[0039] The second puncture section 412 also serves as a separator, which simplifies the structure of the fluid-conducting connection structure 4, makes it easier to manufacture, and helps reduce costs.

[0040] Please refer to Figure 3 , Figure 5 and Figure 6 In one embodiment, the second puncture portion 412 is configured as a non-straight plate structure, for example, the second puncture portion 412 is configured as an arc-shaped structure, forming a C-shaped structure in the radial cross-sectional direction of the tubular body 41. This configuration can improve the structural strength of the second puncture portion 412, making it less prone to deformation when the sealing membrane 32 is opened; the C-shaped second puncture portion 412 can also form an approximately rugby ball-shaped second through hole 414 with the inner wall of the tubular body 41, with a wider middle position of the second through hole 414, which is more conducive to air conduction.

[0041] Please refer to Figure 5 In one embodiment, the fluid guiding connection structure 4 is provided with a mounting part 42, which protrudes radially outward from the tubular body 41. The mounting part 42 and the tubular body 41 can be an integral structure. The mounting part 42 can be an annular protrusion located on the tubular body 41 away from the first puncture part 411. The mounting part 42 has a larger outer diameter than the tubular body 41.

[0042] When the liquid guiding connection structure 4 is inserted into the liquid storage tank 3, the mounting part 42 is inserted into the liquid outlet 31 of the liquid storage tank 3. The mounting part 42 with a larger outer diameter can be connected to the liquid outlet 31 in a snap-fit ​​sealing manner to prevent leakage at the connection.

[0043] Please refer to Figure 3In one embodiment, the liquid storage tank 3 can be assembled from multiple components. For example, the liquid storage tank 3 includes an upper cover 3a, a support plate 3b, a sealing silicone 3c, and a lower cover 3d. The upper cover 3a is a cap-shaped structure with an opening at its lower end and a closed structure at its upper end and sides. The support plate 3b, the sealing silicone 3c, and the lower cover 3d are sequentially stacked on the lower end of the upper cover 3a. The support plate 3b and the lower cover 3d are rigid structures, while the sealing silicone 3c is a flexible structure. The support plate 3b and the lower cover 3d clamp and fix the sealing silicone 3c located in the middle.

[0044] The upper cover 3a and the support plate 3b form a liquid storage cavity. The stacked structure of the support plate 3b, the sealing silicone 3c and the lower cover 3d is provided with a liquid outlet 31. The sealing silicone 3c has a sealing film 32 inside the liquid outlet 31 to seal the liquid outlet 31. The sealing film 32 blocks the liquid outlet 31 so that the liquid storage chamber 3 is in a sealed state when it is not installed, which can prevent leakage.

[0045] The liquid reservoir 3 may also be provided with a clearance hole 3e to avoid the atomizer coil 2. The clearance hole 3e extends through the entire liquid reservoir 3 and is not connected to the liquid storage chamber inside the liquid reservoir 3. When the liquid reservoir 3 is installed in the electronic atomizer, part of the atomizer coil 2 passes through the clearance hole 3e and connects to the mouthpiece 111. This design can increase the capacity of the liquid reservoir 3 and extend the battery life of the electronic atomizer.

[0046] Please refer to Figure 3 and Figure 4 In one embodiment, the sealing membrane 32 includes a central region 321 and a puncture region 322. The thickness of the puncture region 322 is less than the thickness of the central region 321, and the puncture region 322 is an annular groove surrounding the central region 321. With this configuration, when the liquid-conducting connection structure 4 punctures the sealing membrane 32, the thinner annular puncture region 322 aligns with the first puncture part 411, allowing the first puncture part 411 to directly puncture and break the sealing membrane 32 at the puncture region 322. Meanwhile, the thicker central region 321 is pushed aside by the second puncture part 412, making the central region 321 less prone to breakage. This allows the sealing membrane 32 to be opened along the annular puncture region 322, much like opening a door, allowing for a larger opening diameter of the liquid outlet 31, which is more conducive to liquid discharge.

[0047] Please refer to Figure 3 and Figure 4 In one embodiment, the inner wall of the outlet 31 is further provided with a raised sealing portion 311, which can be one or more annular silicone structures. When the liquid guiding connection structure 4 is inserted into the outlet 31, the tubular body 41 and the sealing portion 311 form a compression-type sealing connection, or the mounting portion 42 and the sealing portion 311 form a compression-type sealing connection. This arrangement can improve the sealing performance of the connection between the liquid guiding connection structure 4 and the outlet 31 after insertion, and prevent leakage.

[0048] In one embodiment, the sealing part 311 and the sealing membrane 32 are an integrated structure, and the sealing part 311 and the sealing membrane 32 are different parts of the same silicone pad. That is, the liquid outlet 31 is a through hole on the silicone pad. This arrangement simplifies the structure of the liquid storage tank 3 and facilitates installation and manufacturing.

[0049] Please refer to Figures 3 to 6 In one embodiment, a liquid guiding connection structure for an electronic atomizer is provided. This liquid guiding connection structure is the liquid guiding connection structure 4 in any of the above embodiments. The liquid guiding connection structure 4 is used to be installed inside the electronic atomizer to puncture the sealing membrane 32 of the liquid storage chamber 3.

[0050] In other embodiments, this liquid-conducting connection structure can also be applied to other electronic atomizers to achieve a puncture connection with a removable liquid reservoir 3.

[0051] In this embodiment, the liquid-conducting connection structure 4 includes a tubular body 41, which has a first puncture portion 411 and a second puncture portion 412. The first puncture portion 411 is located at the end of the tubular body 41 and has a sharp structure. The second puncture portion 412 is located in the middle of the tubular body 41 and has a more blunt puncture structure. The radial inclination of the first puncture portion 411 relative to the tubular body 41 is greater than that of the second puncture portion 412 relative to the tubular body 41. The end of the first puncture portion 411 is smaller and narrower, making it easier to puncture the sealing membrane 32. The second puncture portion 412 forms a radially wider inclined knife-shaped structure. The second puncture portion 412 is used to open the sealing membrane 32 to open a larger diameter of the liquid outlet 31, thereby achieving a larger liquid inlet flow rate to meet the liquid inlet requirements of the atomizing core 2.

[0052] The first puncture portion 411 can be formed by extending the tubular body 41 axially, that is, the first puncture portion 411 and the tubular body 41 form an integrated structure, which is convenient for manufacturing. The second puncture portion 412 can be located in the cavity of the tubular body 41. The second puncture portion 412 and the first puncture portion 411 can form an intersecting structure on the radial cross-section of the tubular body 41. This structure forms a puncture structure similar to a T-shaped cross-section, which can improve the structural strength of the puncture structure, making it less prone to deformation. It can ensure that the puncture structure can puncture the sealing membrane 32, and can easily push open a larger area of ​​the punctured sealing membrane 32 to open a larger diameter of the liquid outlet 31.

[0053] In this embodiment, since the liquid guiding connection structure 4 is provided with a first puncture part 411 and a second puncture part 412, the first puncture part 411 and the second puncture part 412 have different inclinations. The first puncture part 411 with a larger inclination can be used to puncture and break the sealing membrane 32 at the liquid outlet 31 of the liquid storage chamber 3. The second puncture part 412 with a smaller inclination has a wide lateral volume, which can expand the sealing membrane 32 to form a larger liquid outlet cross section, which can ensure the successful liquid outlet of the liquid storage chamber and ensure the liquid flow rate. This replaces the solution of using multiple liquid guiding connection structures to form multiple liquid outlets to increase the liquid flow rate in traditional electronic atomizers. This electronic atomizer can achieve this with a single liquid guiding connection structure 4. The number of liquid guiding connection structures 4 is small, which can reduce their space occupation and reduce manufacturing costs.

[0054] In one embodiment, the second puncture portion 412 extends into the tubular body 41, from one end to the other. The second puncture portion 412 divides the inner cavity of the tubular body 41 into a first through-hole 413 and a second through-hole 414, with the two through-holes being of different sizes. The radial cross-sectional area of ​​the first through-hole 413 is larger than that of the second through-hole 414. This configuration allows the larger first through-hole 413 to be used for liquid guidance, while the smaller second through-hole 414 can be used for gas guidance, enabling simultaneous liquid drainage and air intake from the liquid storage chamber 3, achieving gas-liquid circulation, and ensuring that the liquid atomizing matrix within the liquid storage chamber 3 can flow smoothly into the atomizing core 2.

[0055] The second puncture section 412 also serves as a separator, which simplifies the structure of the fluid-conducting connection structure 4, makes it easier to manufacture, and helps reduce costs.

[0056] In one embodiment, the second puncture portion 412 is configured as a non-straight plate structure, for example, the second puncture portion 412 is configured as an arc-shaped structure, forming a C-shaped structure in the radial cross-sectional direction of the tubular body 41. This configuration can improve the structural strength of the second puncture portion 412, making it less prone to deformation when the sealing membrane 32 is opened; the C-shaped second puncture portion 412 can also form an approximately rugby ball-shaped second through hole 414 with the inner wall of the tubular body 41, with a wider middle position of the second through hole 414, which is more conducive to air conduction.

[0057] In one embodiment, the fluid guiding connection structure 4 is provided with a mounting part 42, which protrudes radially outward from the tubular body 41. The mounting part 42 and the tubular body 41 can be an integral structure. The mounting part 42 can be an annular protrusion located on the tubular body 41 away from the first puncture part 411. The mounting part 42 has a larger outer diameter than the tubular body 41.

[0058] When the liquid guiding connection structure 4 is inserted into the liquid storage tank 3, the mounting part 42 is inserted into the liquid outlet 31 of the liquid storage tank 3. The mounting part 42 with a larger outer diameter can be connected to the liquid outlet 31 in a snap-fit ​​sealing manner to prevent leakage at the connection.

[0059] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
