Description

Technical Field

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

[0002] An electronic atomization device is a device used to generate aerosols from an aerosol-generating matrix.

[0003] Currently, conventional electronic atomizing devices can replenish the liquid matrix inside the atomizer through an open filling structure, thus solving the problem of the liquid matrix being continuously consumed during the atomization process. Existing open atomizers fill the liquid into the reservoir chamber and then guide it to the area around the heating element used for heating and atomization through an oil-separating component.

[0004] However, the liquid delivery efficiency of open-type atomizers is currently low, which affects the overall efficiency of liquid matrix addition. Utility Model Content

[0005] The purpose of this invention is to provide an atomizer and an electronic atomizing device to improve the liquid conduction efficiency of the atomizer, thereby improving the overall efficiency of liquid matrix filling.

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

[0007] An atomizer, comprising:

[0008] The outer casing has a liquid storage chamber inside for storing a liquid matrix;

[0009] A liquid separator is at least partially disposed within the liquid storage cavity, the liquid separator dividing the liquid storage cavity into a first liquid storage cavity located within the liquid separator and a second liquid storage cavity located outside the liquid separator, and the liquid separator is provided with a first liquid passage hole communicating with the first liquid storage cavity and the second liquid storage cavity;

[0010] A support is disposed within the first liquid storage chamber, and the support is provided with a second liquid passage hole;

[0011] A heating element is disposed within the support, and the heating element is used to heat the liquid matrix to generate an aerosol.

[0012] The liquid matrix in the second liquid storage chamber can flow into the heating core through the first liquid passage and the second liquid passage in sequence, and at least a portion of the first liquid passage and at least a portion of the second liquid passage are on the same horizontal plane along the direction from the outside to the inside.

[0013] As an alternative to the atomizer, the atomizer includes a seal disposed within the housing, the seal and the housing together defining the boundary of the second liquid reservoir, and one end of the liquid separator is inserted into the seal.

[0014] As an alternative to the atomizer, the surface of the seal facing the second liquid reservoir has a guide surface that is inclined toward the first liquid passage.

[0015] As an alternative to the atomizer, the sealing element has a protruding guide portion on its surface facing the second liquid storage chamber. The guide portion is spaced apart from the liquid separator and surrounds at least a portion of the liquid separator.

[0016] As an alternative to the atomizer, the flow guide includes a first flow guide and a second flow guide that are spaced apart, with a gap formed between the first flow guide and the second flow guide, and the gap being disposed opposite to the first liquid passage.

[0017] As an alternative to the atomizer, the liquid inlet on the housing is located above the flow guide and is offset from the first liquid passage in the circumferential direction.

[0018] As an alternative to the atomizer, the atomizer includes an air guide, one end of which is connected to the bracket and the other end is in fluid communication with the outside of the housing. The air guide is provided with a limiting part, which is connected to the other end of the liquid separator.

[0019] As an alternative to the atomizer, the housing is provided with a mouthpiece, which is connected to the other end of the air guide.

[0020] As an alternative to the atomizer, the atomizer further includes a first liquid reservoir disposed within the liquid separator, and the first liquid reservoir is at least partially fitted onto the bracket.

[0021] As an alternative to the atomizer, the inner diameter of the liquid separator ranges from 12mm to 14mm.

[0022] An electronic atomizing device includes a power supply unit and an atomizer as described in any of the above embodiments, wherein the power supply unit is used to supply power to the atomizer.

[0023] Beneficial effects:

[0024] In the first aspect of this invention, the liquid matrix in the second liquid storage chamber flows sequentially through the first and second liquid passages into the heating core. Upon contact with the heating core, the liquid matrix vaporizes upon heating and combines with air to generate an aerosol for the user to inhale. Furthermore, by ensuring that at least a portion of the first and second liquid passages are on the same horizontal plane from the outside in, and that at least a portion of the first and second liquid passages are opposite each other on the same horizontal plane, the flow rate of the liquid matrix from the outside in (from the second liquid storage chamber to the heating core) can be increased, allowing the liquid matrix to enter and contact the heating core more quickly. On the other hand, when adding liquid matrix into the liquid storage chamber, it can also quickly reach the heating core through the first and second liquid passages, effectively improving the user experience.

[0025] In a second aspect of this invention, the power supply unit of the atomizer can improve the liquid conduction efficiency of the atomizer, thereby improving the overall efficiency of liquid matrix addition. Furthermore, users can dynamically replenish the liquid matrix while using the electronic atomizing device to ensure uninterrupted use. Attached Figure Description

[0044] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0048] Please see the appendix Figure 1 and attached Figure 2 The first aspect of this embodiment relates to an atomizer 200, which includes a housing 1, a support 2, a liquid separator 3, and a heating element 5. The housing 1 has a storage chamber 11 for storing a liquid matrix; the liquid separator 3 is at least partially disposed within the storage chamber 11, dividing the storage chamber 11 into a first storage chamber 111 located within the liquid separator 3 and a second storage chamber 112 located outside the liquid separator 3; the liquid separator 3 has a first liquid passage 31 communicating with the first and second storage chambers 111 and 112; the support 2 is disposed within the first storage chamber 111, and has a second liquid passage 21; the heating element 5 is disposed within the support 2, and is used to heat the liquid matrix to generate an aerosol; the liquid matrix in the second storage chamber 112 can flow into the heating element 5 sequentially through the first and second liquid passages 31 and 21, with at least a portion of the first and second liquid passages 31 and 21 being on the same horizontal plane along an outside-to-inside direction.

[0049] It should be noted that the liquid matrix is ​​a liquid aerosol-generating matrix. The aerosol-generating matrix may include tobacco-containing materials containing volatile tobacco flavor compounds that are released from the substrate upon heating. The liquid matrix may include liquids such as glycerol or propylene glycol, which, upon vaporization, generate an aerosol that can be inhaled by the user.

[0050] Specifically, the internal space of the outer shell 1 forms a liquid storage chamber 11, which is used to store the liquid matrix. After the atomizer 200 is powered on, it can atomize the liquid matrix to form an aerosol. In this embodiment, the main body of the outer shell 1 is cylindrical, and the liquid storage chamber 11 is also a cylindrical chamber. Of course, in other embodiments, the outer shell 1 can also have other structures, such as a flat cylindrical structure with an elliptical cross section.

[0051] The liquid separator 3 is a cylindrical sleeve structure, at least partially erected inside the liquid storage cavity 11. The inner and outer sides of the liquid separator 3 divide the liquid storage cavity 11 into a first liquid storage cavity 111 and a second liquid storage cavity 112. Currently, the inner diameter of the liquid separator 3 ranges from 12mm to 14mm. A first liquid passage hole 31 is formed on the wall of the liquid separator 3. This application provides two first liquid passage holes 31, which are oppositely arranged circular holes. The support 2 is also a cylindrical sleeve structure and is located inside the first liquid storage cavity 111. Multiple second liquid passage holes 21 are formed on the support 2. The second liquid passage holes 21 can have various shapes, including circular holes, strip holes, or square holes. The heating element 5 is a mesh-like heating plate with an overall cylindrical structure. A wire for conducting electricity is welded to the inner wall of the heating element 5. When energized, the heating element 5 heats up through the resistance heating effect to heat the liquid matrix.

[0052] In this embodiment, the liquid matrix in the second liquid storage chamber 112 flows into the heating core 5 sequentially through the first liquid passage 31 and the second liquid passage 21. After contacting the heating core 5, the liquid matrix vaporizes upon heating and combines with air to generate an aerosol for the user to inhale. Furthermore, by ensuring that at least a portion of the first liquid passage 31 and at least a portion of the second liquid passage 21 are on the same horizontal plane from the outside to the inside, and that the first liquid passage 31 and the second liquid passage 21 are at least partially opposite each other on the same horizontal plane, the flow rate of the liquid matrix from the outside to the inside (from the second liquid storage chamber 112 to the heating core 5) can be increased, ensuring that the liquid matrix enters and contacts the heating core 5 more quickly. Additionally, when adding liquid matrix into the liquid storage chamber 11, it can quickly reach the heating core 5 through the first liquid passage 31 and the second liquid passage 21, effectively improving the user experience.

[0053] Optionally, the atomizer 200 includes a seal 4 disposed within the housing 1, the seal 4 and the housing 1 together defining the boundary of the second liquid storage chamber 112, and one end of the liquid separator 3 is inserted into the seal 4.

[0054] In this embodiment, the sealing element 4 is made of silicone and is located at the bottom of the liquid storage cavity 11. Its tight fit with the outer shell 1 ensures the airtightness of the internal space of the liquid storage cavity 11. A cylindrical mounting groove is formed on the sealing element 4, and multiple annular platforms protrude inward from the inner wall of the mounting groove. One end of the liquid separator 3 is inserted into the mounting groove and presses against the annular platforms to form a seal. Simultaneously, an air inlet is provided on the bottom wall of the mounting groove, which communicates with the second liquid storage cavity 112 to facilitate the entry of air into the second liquid storage cavity 112.

[0055] Please continue to refer to the appendix. Figure 1 -Appendix Figure 3 Optionally, the surface of the seal 4 facing the second liquid storage chamber 112 has a guide surface 41 that is inclined toward the first liquid passage 31.

[0056] In this embodiment, the guide surface 41 is an annular surface and is inclined. The liquid matrix can flow down along the guide surface 41 and accumulate on the outer periphery of the liquid separator 3, which further accelerates the introduction of the liquid matrix into the first liquid passage 31 and improves the liquid guiding efficiency.

[0057] Please see the appendix Figure 3 Furthermore, the surface of the sealing member 4 facing the second liquid storage chamber 112 is provided with a guide portion 42, which is spaced apart from the liquid separator 3 and surrounds at least part of the liquid separator 3.

[0058] Specifically, the guide section 42 can be integrated with the seal 4. On the one hand, during liquid injection, the liquid matrix continuously converges along the guide surface 41 into the gap between the guide section 42 and the seal 4, and passes through the first liquid passage 31 through the guide effect of the guide section 42, thereby ensuring liquid guiding efficiency. On the other hand, as the atomizer 200 is used continuously, the liquid matrix will be consumed and reduced. The user can manually flip the atomizer, and the remaining liquid matrix will converge again near the first liquid passage 31 through the guiding effect of the guide section 42, and participate in atomization more easily, thereby ensuring that the atomizing matrix is ​​used up or nearly used up.

[0059] Optionally, the flow guide 42 includes a first flow guide 421 and a second flow guide 422 that are spaced apart, with a gap 43 formed between the first flow guide 421 and the second flow guide 422, and the gap 43 is disposed opposite to the first liquid passage 31.

[0060] Specifically, the first guide section 421 and the second guide section 422 are arranged opposite to each other and have the same structure. Two gaps 43 are formed between the two ends of the first guide section 421 and the second guide section 422.

[0061] In this embodiment, a gap 43 opposite to the first liquid passage 31 is formed between the separately provided first guide portion 421 and second guide portion 422. During the liquid injection operation, the liquid matrix can enter the first liquid passage 31 through the gap 43 by the guiding effect of the first guide portion 421 and second guide portion 422, thereby improving the liquid guiding efficiency.

[0062] Please see the appendix Figure 4 and attached Figure 5 Optionally, the liquid injection port 12 on the outer casing 1 is located above the flow guide 42 and is offset from the first liquid passage 31 in the circumferential direction.

[0063] Specifically, the injection port 12 is used to inject a liquid matrix into the storage chamber 11. The injection port 12 is sealed by the injection plug 7 to prevent leakage of the liquid matrix. The injection port 12 is higher than the guide section 42. During injection, the liquid matrix can flow into the guide section 42 along the inner wall of the storage chamber 11 by gravity, ensuring the effectiveness of the guide section 42 in guiding the liquid. The size of the injection port 12 needs to be adapted to the size of the injection device to ensure no leakage during the injection process after fitting.

[0064] Optionally, the atomizer 200 includes an air guide 6, one end of which is connected to the bracket 2 and the other end is in fluid communication with the outside of the housing 1. The air guide 6 is provided with a limiting part 61, which is connected to the other end of the liquid separator 3.

[0065] Specifically, after the air guide 6 is connected to the support 2, the air guide channel inside the air guide 6 communicates with the interior of the support 2, thereby ensuring that the vaporized aerosol can be discharged through the air guide channel. One end of the air guide 6 is inserted into the support 2, and the other end can be connected to the suction nozzle formed by the outer shell 1. After the user holds the suction nozzle in their mouth, they can draw in the aerosol to enter the oral cavity through the air guide channel. The radial dimensions of the air guide 6 and the support 2 are similar. The outer wall of the air guide 6 is provided with a limiting part 61, which is an annular circular plate structure. The limiting part 61 is inserted into the other end of the liquid separator 3 and closes one side of the first liquid storage chamber 111.

[0066] Furthermore, the atomizer 200 also includes a first liquid reservoir 8, which is disposed within the liquid separator 3 and is at least partially fitted onto the bracket 2.

[0067] In this embodiment, the first liquid storage component 8 is a liquid storage cotton with a loose and porous structure. The first liquid storage component 8 fills the first liquid storage cavity 111, which can lock the liquid matrix entering the first liquid storage cavity 111, and at the same time can provide the liquid matrix in the first liquid storage cavity 111 to the heating core 5 inside the support 2 in a timely manner. A base 32 is provided at the bottom inside the liquid separator 3. The base 32 is sleeved on part of the structure of the support 2, and the first liquid storage component 8 is placed on the base 32 for support. The base 32 is made of plastic material, which can ensure liquid sealing through tight fit.

[0068] Furthermore, the outer casing 1 is provided with a suction nozzle 13, which is connected to the other end of the air guide 6.

[0069] Specifically, the suction nozzle 13 is the connecting part of the suction nozzle on the outer shell 1 that extends into the liquid storage cavity 11, and the air guide 6 is directly inserted into the suction nozzle 13. The two are tightly fitted together to ensure an airtight seal.

[0070] In this embodiment, the air guide 6 is directly inserted into the nozzle portion 13, and the first liquid storage component 8 is sealed by the limiting portion 61 of the air guide 6, thus preventing the liquid separator 3 from being directly inserted into the nozzle portion 13 for connection. Therefore, the radial dimension of the liquid separator 3 can be appropriately increased, and the dimensions of the first liquid storage chamber 111 and the first liquid storage component 8 can also be adaptively increased. Furthermore, the radial dimension of the overall outer shell 1 can be appropriately increased, and the length dimension can be appropriately decreased, thereby improving the overall appearance of the atomizer 200.

[0071] Optionally, the atomizer 200 also includes a second liquid reservoir 9, which is also a liquid reservoir cotton. The second liquid reservoir 9 fills the receiving cavity 22 inside the support 2. A limiting platform is provided on the inner wall of the support 2, and the second liquid reservoir 9 abuts against the limiting platform. At the same time, the second liquid reservoir 9 is sleeved on the outer periphery of the heating core 5. The second liquid reservoir 9 can absorb the liquid matrix passing through the second liquid passage 21 and directly contact the heating core 5.

[0072] Please refer to the attached document. Figure 6 The second aspect of this embodiment relates to an electronic atomizing device, which includes a power supply unit 100 and one or more atomizers 200.

[0073] Specifically, the power supply unit 100 has a rechargeable power source inside, and one end of the power supply unit 100 forms a receiving cavity 110, into which part of the atomizer 200 can be inserted. When the atomizer 200 is installed in the power supply unit 100, the two can be electrically connected, and the power supply unit 100 can supply power to the atomizer 200. At the bottom of the atomizer 200, there is a bottom shell 10 that can cooperate with the outer shell 1. Multiple magnetic components 101 are embedded in the bottom shell 10. The magnetic components 101 can be permanent magnets. Correspondingly, the bottom of the receiving cavity 110 is also provided with a permanent magnet so that the atomizer 200 and the power supply unit 100 are attracted by magnetic force, ensuring that the atomizer 200 and the power supply unit 100 maintain a stable insertion and electrical connection.

[0074] Based on the power supply unit 100 of this atomizer 200, the liquid conduction efficiency of the atomizer 200 can be improved, thereby increasing the overall efficiency of liquid matrix addition. Furthermore, users can dynamically replenish the liquid matrix while using the electronic atomization device to ensure uninterrupted use.

[0075] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
