Description

Technical Field

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

[0002] An electronic atomizing device is an electronic product that atomizes a liquid matrix to produce an aerosol for users to inhale. It typically consists of a detachable atomizer and a power supply assembly. The atomizer heats the internal liquid matrix to generate an aerosol, while the power supply assembly provides power to the atomizer. The atomizer includes a liquid reservoir, an atomizing assembly, and a liquid storage element. The liquid storage element stores a portion of the liquid matrix from the reservoir and transfers it to the atomizing assembly for atomization to produce an aerosol.

[0003] In the process of realizing this application, the inventors discovered that since there are usually air bubbles in the liquid storage chamber, these air bubbles will expand when subjected to changes in temperature or air pressure. Thus, when the electronic atomizing device is inverted, the expanded air bubbles will squeeze the liquid matrix, causing the liquid matrix to flow out from the atomizing component and leak out of the electronic atomizing device along the internal airflow channel. Utility Model Content

[0020] To solve the aforementioned technical problems, another technical solution adopted in this application is: providing another atomizer, including a housing, a first tube, an atomizing assembly, and an air guide tube. The housing defines a liquid storage chamber for storing a liquid matrix and an air outlet for providing aerosol output. The first tube extends within the liquid storage chamber. The atomizing assembly includes a second tube and a heating element located within the second tube. The second tube is disposed within the hollow cavity of the first tube. The air guide tube is used to conduct the aerosol. One end of the air guide tube communicates with the air outlet, and the other end remains in communication with the second tube. A first gap extending axially along the first tube body is maintained between the first tube body and the second tube body. The first gap is filled with a first liquid storage element and a second liquid storage element spaced apart along the axial direction of the first tube body.

[0022] The beneficial effects of this application embodiment are as follows: Unlike the prior art, this application embodiment provides an atomizer including a housing, a support base, and an atomizing component. The housing defines a liquid storage chamber for storing a liquid matrix. The atomizing component is used to atomize the liquid matrix to generate an aerosol. The support base includes a base for supporting the atomizing component and a first tube extending from the base toward the liquid storage chamber. The atomizing component includes a second tube, at least a portion of which is disposed within the hollow cavity of the first tube and maintains a first gap extending axially along the first tube. The first gap is filled with a first liquid storage element and a second liquid storage element spaced apart along the axial direction of the first tube. The first liquid storage element communicates with the liquid storage chamber and the atomizing component, thereby transferring the liquid matrix in the liquid storage chamber to the atomizing component. The housing is also provided with an outlet for the aerosol to escape from the atomizer. The second liquid storage element is closer to the outlet than the first liquid storage element. With the above structure, in this embodiment of the application, the first and second liquid storage components, which are spaced apart, allow the liquid matrix in the storage chamber to be absorbed by the second liquid storage component when the liquid matrix exceeds the storage capacity of the first liquid storage component due to the squeezing action of the bubbles in the storage chamber. This is achieved by relying on the capillary force and gravity of the liquid matrix, thus preventing the liquid matrix from flowing to the outside and affecting the user's experience.

It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0026] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0027] This application provides an atomizer 100; please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3The atomizer 100 includes a housing 1, an atomizing component 2, and a support 3. The housing 1 defines a liquid storage chamber 11 for storing a liquid matrix. The atomizing component 2 is disposed in the housing 1 and is in fluid communication with the liquid storage chamber 11, so that the liquid matrix in the liquid storage chamber 11 can be transferred to the atomizing component 2. The atomizing component 2 is used to atomize the liquid matrix to generate an aerosol. The support 3 includes a base 31 for supporting the atomizing component 2 and a first tube 32 extending from the base 31 toward the liquid storage chamber 11. The first tube 32 is a tubular structure with a hollow cavity 321. The atomizing component 2 includes a second tube 21, at least a portion of which is disposed within the hollow cavity 321 of the first tube 32. The center lines of the first tube 32 and the second tube 21 are collinear. The second tube 21 and the first tube 32 maintain a first gap S1 extending along the axial direction of the first tube 32. The first gap S1 is filled with a first liquid storage element 4 and a second liquid storage element 5 spaced apart along the axial direction of the first tube 32. The first liquid storage element 4 and the second liquid storage element 5 are constructed in an annular shape and surround the second tube 21. The first liquid storage element 4 connects the liquid storage chamber 11 and the atomizing component 2, thereby transferring the liquid matrix in the liquid storage chamber 11 to the atomizing component 2. The housing 1 is also provided with an outlet 12 for the aerosol to escape from the atomizer 100. The second liquid storage element 5 is closer to the outlet 12 than the first liquid storage element 4.

[0028] With the above structure, when the atomizer 100 is inverted and subjected to temperature or pressure, the volume of the bubbles in the liquid storage chamber 11 increases, thereby squeezing the liquid matrix in the liquid storage chamber 11. This causes the liquid matrix to overflow from the first liquid storage component 4. The liquid matrix overflowing from the first liquid storage component 4 can flow to the second liquid storage component 5, which is spaced apart from the first liquid storage component 4, under the influence of its own gravity. Thus, the overflowing liquid matrix is ​​stored in the second liquid storage component 5. Furthermore, as the liquid matrix is ​​transferred between the first liquid storage component 4 and the second liquid storage component 5, the porous structure of the liquid storage component itself will cause capillary action between the first liquid storage component 4 and the second liquid storage component 5, further ensuring that the liquid matrix overflowing from the first liquid storage component 4 can be absorbed and stored by the second liquid storage component 5, thus preventing the liquid matrix from leaking to the outside of the electronic device and affecting the user's use.

[0029] Furthermore, the first tube 32 is directly formed from the support base 3 that supports the atomizing component 2, eliminating the need for a separate additional first tube 32, which can reduce the manufacturing cost of the atomizer 100.

[0030] Understandably, the liquid matrix may contain a liquid containing tobacco-containing substances with volatile tobacco flavor components, or it may contain a liquid containing non-tobacco substances. The liquid matrix may contain water, pharmaceutical solutions, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures, etc. Fragrances may include areca nut extract, menthol, peppermint, spearmint oil, various fruit flavor components, etc., but are not limited to these. Flavorings may contain ingredients that can provide the user with various fragrances or flavors. Vitamin mixtures may be mixtures containing at least one of vitamins A, B, C, and E, but are not limited to these. Based on the different properties of the liquid matrix, the atomizer 100 can be used in different fields, such as medical and electronic aerosol atomization.

[0031] It should be noted that the second liquid storage component 5 is closer to the air outlet 12 than the first liquid storage component 4. This ensures that when the atomizer 100 is inverted, the liquid matrix overflowing from the first liquid storage component 4 is preferentially absorbed by the second liquid storage component 5, and will not leak directly from the air outlet 12 into the external environment. This ensures the atomizer 100's ability to prevent the liquid matrix from leaking into the outside environment.

[0032] The materials of the first liquid storage component 4 and the second liquid storage component 5 need to ensure that they have a loose and porous structure to ensure that they can adsorb and store the liquid matrix. Common optional materials for the first liquid storage component 4 and the second liquid storage component 5 are: fiber cotton, porous ceramic, organic cotton or undyed cotton, non-woven fabric or fiberglass rope, etc.

[0033] It is understandable that the first liquid reservoir 4 and the second liquid reservoir 5 are fixed in the first gap S1 by methods including but not limited to: adhesive bonding, interference fit, snap-fit, welding, etc. Examples will not be provided here.

[0034] For further explanation, please refer to [link / reference]. Figure 4 and Figure 5 The first liquid storage component 4 and the second liquid storage component 5, which are spaced apart, can form a second gap S2 between the first liquid storage component 4 and the second liquid storage component 5. The existence of the second gap S2 allows the first liquid storage component 4 and the second liquid storage component 5 to form two independent components. When no overflow occurs, the liquid matrix stored in the first liquid storage component 4 forms an air isolation layer in the second gap S2, which prevents the liquid matrix in the first liquid storage component 4 from being transferred to the second liquid storage component 5 through physical contact, and ensures that the second liquid storage component 5 can absorb the liquid matrix that overflows from the first liquid storage component 4.

[0035] In some embodiments, a second gap S2 of 0.5 mm to 1.5 mm is maintained between the first liquid reservoir 4 and the second liquid reservoir 5, that is, the width of the second gap S2 is 0.5 mm to 1.5 mm along the axial direction of the first tube body 32.

[0036] Understandably, the lengths of the first liquid storage component 4 and the second liquid storage component 5 along the axial direction of the first tube 32 can be selected according to actual needs. For example, the length of the second liquid storage component 5 can be greater than the length of the first liquid storage component 4 to improve the ability of the second liquid storage component 5 to store the overflowing liquid matrix; or the length of the second liquid storage component 5 can be less than or equal to the length of the first liquid storage component 4 to ensure the rate at which the first liquid storage component 4 transfers the liquid matrix to the atomizing component 2.

[0037] For example, in some preferred embodiments, the absolute value of the difference between the length of the first liquid reservoir 4 and the length of the second liquid reservoir 5 along the axial direction of the first tube 32 is 1 mm.

[0038] In some embodiments, please refer to Figure 3 , Figure 4 and Figure 5 The housing 1 includes an air guide tube 13 extending from the liquid storage chamber 11. One end of the air guide tube 13 defines the aforementioned air outlet 12, and the other end of the air guide tube 13 is connected to the atomizing component 2. The air guide tube 13 is configured to receive and conduct aerosol to the air outlet 12 so that the generated aerosol can be delivered to the external environment through the air outlet 12 for the user to inhale. The outer side wall of the air guide tube 13, the inner side wall of the housing 1, and the aforementioned support 3 together define the aforementioned liquid storage chamber 11. The air guide tube 13 is partially inserted into the interior of the second tube body 21, and the center line of the air guide tube 13 and the center line of the second tube body 21 are co-aligned. A third gap S3 is maintained radially between the air guide tube 13 and the second tube body 21. The third gap S3 is used to construct a microchannel that keeps the interior of the second liquid storage component 5 and the second tube body 21 connected. Since the atomizing component 2 is located inside the second tube 21 and the atomizing component 2 and the first liquid storage component 4 are in fluid communication, the liquid matrix squeezed out by the increased volume of the bubbles in the liquid storage chamber 11 will also overflow from the atomizing component 2. The microchannel that is connected to the second liquid storage component 5 and the second tube 21 allows the liquid matrix overflowing from the atomizing component 2 to flow to the second liquid storage component 5 and be absorbed and stored by the second liquid storage component 5 when the atomizer 100 is inverted due to the capillary action of the microchannel.

[0039] It should be noted that when the liquid matrix flows from the microchannel to the second liquid storage device 5, it mainly relies on capillary force to generate capillary phenomenon. Therefore, along the radial direction of the second tube 21, the width of the third gap S3 is 0.1 mm to 0.3 mm to ensure the normal occurrence of capillary phenomenon.

[0040] In some embodiments, please refer to Figure 5The end face of the air guide tube 13 facing the atomizing component 2 is closer to the air outlet 12 than the end face of the second liquid storage component 5 facing the first liquid storage component 4. Through the above structural design, when the atomizer 100 is inverted, the liquid matrix overflowing from the first liquid storage component 4 and the atomizing component 2 can be effectively guided and trapped in the second liquid storage component 5 under the combined drive of gravity and capillary action, preventing the overflowing liquid matrix from entering the air guide tube 13, thereby significantly reducing the risk of liquid matrix leakage from the air outlet 12, and further enhancing the leakage prevention capability and reliability of the atomizer 100 under complex usage postures.

[0041] In some embodiments, please refer to Figure 5 , Figure 10 and Figure 11 The atomizing component 2 includes a third liquid storage element 22 located inside the second tube 21, and a heating element 23 attached to the third liquid storage element 22. The third liquid storage element 22 is constructed in a ring shape. The first liquid storage element 4 surrounds the second tube 21 and has at least partial radial overlap with the third liquid storage element 22 to ensure that the liquid matrix absorbed and stored by the first liquid storage element 4 can be transported to the third liquid storage element 22. Then, the third liquid storage element 22 can further transfer the liquid matrix to the heating element 23 for heating and atomization. The second liquid storage element 5 surrounds the second tube 21 and avoids the third liquid storage element 22 to prevent the third liquid storage element 22 from forming physical contact with the second liquid storage element 5.

[0042] Furthermore, the second tube 21 is provided with at least one connecting hole 211. The inner side wall of the first liquid storage component 4 and the outer side wall of the third liquid storage component 22 together clamp and cover the connecting hole 211. The connecting hole 211 allows the liquid matrix stored in the first liquid storage component 4 to be transferred to the third liquid storage component 22 through the connecting hole 211.

[0043] In some embodiments, please refer to Figure 6 and Figure 7 Along the axial direction of the first tube 32, a portion of the second liquid storage component 5 surrounds the second tube 21, and another portion of the second liquid storage component 5 surrounds the air guide tube 13, so that the end of the second tube 21 is located in the second liquid storage component 5, and the second tube 21 does not pass through the second liquid storage component 5, thereby allowing the liquid matrix overflowing from the atomizing component 2 to adhere to and flow along the inner sidewall of the second tube 21 through the microchannel constructed by the third gap S3 into the second liquid storage component 5.

[0044] To facilitate understanding of the working principle of microchannels, a simple analysis is provided here. When the atomizer 100 is inverted, the end face of the air guide tube 13 is higher than the lower end face of the second liquid reservoir 5 and lower than the upper end face of the second liquid reservoir 5 along the axial direction of the first tube 32. That is, a gap is formed between the end face of the air guide tube 13 and the third liquid reservoir 22. This gap allows the liquid matrix to be guided by the inner wall of the second tube 21 when it overflows from the atomizing component 2. Under the gravity of the liquid matrix itself, it tends to flow to the third gap S3. However, since the liquid matrix itself has surface tension, the surface tension will hinder the flow tendency of the liquid matrix under its own gravity. As the total amount of liquid matrix overflowing from the atomizing component 2 increases, when the gravity is greater than the surface tension, the liquid matrix will flow. Compared to the method of setting the end face of the air guide tube 13 along the axial direction of the first tube body 32 to be higher than the end face of the second liquid storage component 5 near the first liquid storage component 4 or even higher than the end face of the first liquid storage component 4 near the second liquid storage component 5, in this application, by setting the interval area, the liquid matrix relies on its own gravity to overcome the surface tension and reserve sufficient space, avoiding the situation where the liquid matrix comes into contact with the air guide tube 13 before overcoming the surface tension and flows from the air guide tube 13 to the air outlet 12.

[0045] In some embodiments, a fourth gap S4 is provided between the second liquid storage component 5 and the air guide tube 13. The fourth gap S4 is connected to the third gap S3. The inner sidewall of another part of the second liquid storage component 5 and the outer sidewall of the air guide tube 13 together form the fourth gap S4. The fourth gap S4 is connected to the bottom region of the second liquid storage component 5 along the axial direction of the first tube body 32, so that when a liquid matrix flows into the third gap S3 by gravity to overcome the surface tension, it enters the fourth gap S4. The fourth gap S4 can temporarily store the liquid matrix to prevent it from overflowing from the microchannel when the total amount of liquid matrix flowing into the microchannel in a short time exceeds the absorption rate of the second liquid storage component 5. Furthermore, the fourth gap S4 can also guide the liquid matrix flowing out of the third gap S3 to the bottom region of the second liquid storage component so that the second liquid storage component 5 can absorb the overflowing liquid matrix from the bottom region.

[0046] In some embodiments, please refer to Figure 8 and Figure 9 The air duct 13 includes a first section 131 and a second section 132 with a diameter smaller than that of the first section 131. The second section 132 is inserted into the second tube body 21 and maintains a third gap S3 with the second tube body 21. That is, the outer wall of the second section 132 and the inner wall of the second tube body 21 corresponding to the second section 132 together form the aforementioned third gap S3. That is, the distance between the outer wall of the second section 132 and the inner wall of the second tube body 21 corresponding to the second section 132 is 0.1 mm to 0.3 mm.

[0047] In some embodiments, please refer to Figure 8 , Figure 9 and Figure 10 The atomizer 100 includes a first seal 6, which is configured to seal the gap between the first tube 32 and the air guide tube 13 to provide a barrier between the liquid storage chamber 11 and the second liquid storage element 5. Specifically, the first seal 6 is used to seal the gap between the first tube 32 and the air guide tube 13 to prevent the liquid matrix in the external liquid storage chamber 11 from leaking through the gap.

[0048] Furthermore, along the axial direction of the first tube body 32, the second liquid storage component 5 abuts against the first sealing component 6, so as to determine the installation position of the second liquid storage component 5 during the assembly process, which facilitates mass production.

[0049] In some embodiments, please refer to Figure 9 The sealing element is a sealing ring 61. The inner wall of the sealing ring 61 is provided with sealing ribs 611. The sealing ring 61 elastically abuts between the first pipe body 32 and the air guide pipe 13, thereby providing a seal between the first pipe body 32 and the air guide pipe 13.

[0050] In some embodiments, please refer to Figure 11 The support base 3 also includes an abutment boss 33 extending radially along the first tube body 32 into the first gap S1. The end face of the first liquid storage component 4 away from the second liquid storage component 5 abuts against the abutment boss 33. The abutment boss 33 allows for the positioning of the first liquid storage component 4 during assembly, facilitating the confirmation of its installation position in the first gap S1. Furthermore, the combined action of the abutment boss 33 and the first sealing component 6 not only positions the first liquid storage component 4 and the second liquid storage component 5 within the first gap S1, but also simultaneously determines the position of the second gap S2 and the width of the second gap S2 along the axial direction of the first tube body 32. This structural design is suitable for mass production, reducing labor and material costs during assembly.

[0051] It should be noted that the length and position of the second gap S2 are jointly determined by the length of the first sealing member 6, the length of the second liquid storage member 5, the length of the first liquid storage member 4 and the position of the abutment boss 33 along the axial direction of the first tube body 32. Therefore, one or more of these parameters can be adjusted. Examples will not be given here.

[0052] In some embodiments, please refer to Figure 9The first sealing element 6 includes a first ring body 62 and a second ring body 63 connected together. The outer diameter of the first ring body 62 is larger than the outer diameter of the second ring body 63, so that a first abutting step 64 is formed on the outer side of the connection position of the first ring body 62 and the second ring body 63. The end face of the first tube body 32 extending into the liquid storage cavity 11 abuts against the first abutting step 64, so that during the assembly process, when the first tube body 32 and the air guide tube 13 are inserted into each other, the end face of the first tube body 32 extending into the liquid storage cavity 11 can limit the first sealing element 6 in the insertion direction, and prevent the first sealing element 6 from non-operational. The expected displacement affects the sealing of the gap between the first tube 32 and the air duct 13. Furthermore, the limiting effect of the end face of the first tube 32 and the first abutting step 64 on the first seal 6 ensures that the second liquid storage component 5, whose installation position is determined by abutting the first seal 6, can be successfully installed in the predetermined position. This ensures the accuracy of the installation of the second seal 10 during the assembly process, thereby ensuring that the preset spacing of the second gap S2 meets the design requirements and ensuring the normal operation of the preset functions of the spaced first liquid storage component 4 and the second liquid storage component 5.

[0053] In some embodiments, please refer to Figure 10 and Figure 11 The heating element 23 is arranged around the inner wall of the third liquid storage component 22, and the length of the heating element 23 along the axial direction of the first tube 32 is less than or equal to the length of the third liquid storage component 22, ensuring that the heating range of the heating element 23 always has a liquid matrix to supply for heating to avoid dry burning. The heating element 23 is used to heat and atomize the liquid matrix transmitted through the third liquid storage component 22 and generate an aerosol. The atomizer 100 also includes a base 7 for providing support for the support base 3 and a conductive element 8 disposed on the base 7. The base 7 includes an electrode hole 71. One end of the conductive element 8 is electrically connected to the heating element 23, and the other end of the conductive element 8 is held in the electrode hole 71 and at least partially exposed on the end face of the base 7. The arrangement of the conductive element 8 exposed on the end face of the base 7 allows the conductive element 8 to be connected to an external power supply device, which facilitates the provision of power support for the heating element 23.

[0054] Understandably, the electrical connection methods between the conductive component 8 and the heating component 23 include, but are not limited to, welding connection, wire connection, contact connection, etc.

[0055] For example, in some preferred embodiments, please refer to Figure 8 , Figure 10 and Figure 11The heating element 23 and the conductive element 8 are connected by a wire. Specifically, the heating element 23 includes an electrode lead 231 connected to the conductive element 8. The support base 3 is provided with a wiring groove 34. The end of the conductive element 8 away from the base 7 extends into the wiring groove 34, and the electrode lead 231 extends into the wiring groove 34 and is electrically connected to the conductive element 8. The wiring groove 34 provides a protected and stable cavity to fix the connection position when the heating element 23 and the conductive element 8 are electrically connected through the electrode lead 231. This reduces the risk of loosening or short circuits caused by shaking or vibration. Furthermore, the wiring groove 34 facilitates assembly steps in mass production. The electrical connection can be completed simply by inserting the electrode lead 231 into the wiring groove 34 and then connecting the conductive element 8. This improves assembly efficiency and consistency, reduces alignment difficulty and reliance on skilled workers, and prevents the electrode lead 231 from being excessively bent during assembly or accidentally pulled and damaged in subsequent assembly steps. The mechanical stress at the connection position is also reduced.

[0056] For further details, please refer to Figure 11 The inner wall of the wiring groove 34 is provided with an axially extending limiting protrusion 341. When the conductive component 8 is inserted into the wiring groove 34, the limiting protrusion 341 abuts against the conductive component 8 and generates elastic deformation to hold the conductive component 8 in the wiring groove 34, thereby improving the connection stability of the conductive component 8 inserted into the wiring groove 34.

[0057] It should be noted that, along the radial direction of the wiring groove 34, the height of the limiting protrusion 341 is less than the diameter of the electrode lead 231, so that when the conductive element 8 and the electrode lead 231 are inserted into the wiring groove 34, the side wall of the conductive element 8 and the inner side wall of the wiring groove 34 together clamp the electrode lead 231, ensuring the electrical connection between the conductive element 8 and the electrode lead 231. This structural design ensures the stability of the electrical connection between the conductive element 8 and the electrode lead 231, and also facilitates the later maintenance and replacement of the conductive element 8 or the heating element 23.

[0058] Understandably, there are two conductive elements 8, and correspondingly two electrode leads 231. One electrode lead 231 is electrically connected to one conductive element 8, and one conductive element 8 is used to connect to the positive terminal of an external power source (e.g., a power supply), while the other conductive element 8 is used to connect to the negative terminal of the external power source.

[0059] In some embodiments, please refer to Figure 6 , Figure 10 and Figure 12A liquid-absorbing element 9 is provided between the support base 3 and the base 7. The liquid-absorbing element 9 is connected to the first tube body 32 and is used to absorb the condensate formed after the aerosol condenses to prevent leakage. Understandably, the base 7 and the support base 3 are connected by an insertion method to limit and fix the liquid-absorbing element 9. One of the base 7 and the support base 3 is provided with a receiving groove 72, and the other is provided with a connecting part 35. The liquid-absorbing element 9 is placed in the receiving groove 72, and when the connecting part 35 is inserted into the receiving groove 72, the connecting part 35 and the bottom of the connecting groove 34 together clamp the liquid-absorbing element 9. The material of the liquid-absorbing element 9 can be any of flexible porous materials such as cotton fiber, non-woven fabric, or fiberglass rope.

[0060] For example, in some preferred embodiments, please refer to Figure 13 The base 7 is provided with a receiving groove 72, and the support base 3 extends from the end face away from the first tube body 32 and is provided with a docking part 35. The docking part 35 is inserted into the receiving groove 72, and the liquid suction member 9 is provided at the bottom of the receiving groove 72. When the docking part 35 is inserted into the receiving groove 72, the docking part 35 and the bottom of the receiving groove 72 together clamp the liquid suction member 9.

[0061] Understandably, the base 7 and the support 3 are fixed by interlocking in the following ways, including but not limited to: snap-fit, glued, interference fit, etc.

[0062] For example, in some preferred embodiments, the base 7 and the support 3 are connected by an interference fit.

[0063] In some embodiments, please refer to Figure 6 , Figure 12 and Figure 13 The base 7 is provided with an air guide hole 73, and the support base 3 is provided with an air inlet 36. The air guide hole 73 and the air inlet 36 are connected. Furthermore, the liquid suction element 9 is provided with a first through groove 91 in an annular shape, which connects the air guide hole 73 and the air inlet 36. When the user performs a suction action, air from the outside environment enters the air guide tube 13 after passing through the air guide hole 73, the first through groove 91, and the air inlet 36 in sequence.

[0064] Understandably, the area of ​​the liquid suction component 9 within the receiving tank 72 is selected according to the required volume of the liquid suction component 9. For example, the liquid suction component 9 may only surround the area corresponding to the air guide hole 73 and the air inlet 36, or the liquid suction component 9 may cover the entire bottom of the receiving tank 72.

[0065] For example, in some preferred embodiments, please refer to Figure 13The liquid suction component 9 covers the bottom of the entire receiving tank 72. Furthermore, the liquid suction component 9 is provided with two through holes 92, one of which corresponds to an electrode hole 71 and a wiring groove 34, so that the conductive component 8 can be inserted into the wiring groove 34 from the electrode hole 71. A clearance area is left between the inner wall of the through hole 92 and the inserted conductive component 8 to ensure insulation protection for the conductive component 8.

[0066] In some embodiments, please refer to Figure 6 , Figure 12 and Figure 13 The base 7 extends a limiting ring 74 around the bottom of the receiving groove 72 and the air guide hole 73. The outer ring of the limiting ring 74 abuts against the inner wall of the first through groove 91 so that the limiting ring 74 can radially limit the liquid suction member 9 and prevent the limiting ring 74 from being displaced unexpectedly. The inner ring of the limiting ring 74 forms a second through groove 741, and the end of the second through groove 741 defines the air guide hole 73.

[0067] In some embodiments, the outer side wall of the limiting ring 74 is provided with a guide slope 742 at one end opposite to the air guide hole 73. The guide slope 742 is used to guide the limiting ring 74 to be inserted into the first through groove 91.

[0068] In some embodiments, please refer to Figure 12 The atomizing component 2 also includes a holding ring 24, which is disposed on the inner wall of the second tube 21 and spaced apart from the heating element 23 along the axial direction of the first tube 32. The holding ring 24 is closer to the air inlet 36 than the heating element 23. The holding ring 24 is used to work with the inner wall of the second tube 21 to hold and fix the electrode lead 231, preventing the electrode lead 231 from shaking in the hollow cavity 321 of the second tube 21, and preventing the heating element 23 from being pulled during the assembly process, which would cause the heating element 23 to deform.

[0069] Understandably, the connection methods for connecting the support base 3 to the housing 1 and sealing the opening of the liquid storage cavity 11 include, but are not limited to: interference fit, setting a sealing element, and injecting glue.

[0070] For example, in some preferred embodiments, please refer to Figure 13 A sealing element is used to ensure that the gap at the connection between the support base 3 and the housing 1 can be effectively sealed. Specifically, the atomizer 100 also includes a second sealing element 10. The inner wall of the second sealing element 10 is fitted onto the outer wall of the support base 3, and the outer wall of the second sealing element 10 abuts against the inner wall of the liquid storage cavity 11. The second sealing element 10 is held together by the support base 3 and the housing 1 to ensure the sealing of the liquid storage cavity 11.

[0071] In some embodiments, please refer to Figure 14 and Figure 15The second sealing element 10 includes a third ring 101 and a fourth ring 102. The diameter of the third ring 101 is larger than the diameter of the fourth ring 102, so that a second abutting step 103 is formed on the inner side of the connection position of the third ring 101 and the fourth ring 102. The support seat 3 extends into the periphery of the liquid storage cavity 11 and extends a limiting boss 37. The limiting boss 37 has a first wall surface 371 and a second wall surface 372 arranged adjacently. The first wall surface 371 abuts against the inner wall of the fourth ring 102, and the second wall surface 372 abuts against the second abutting step 103. The limiting boss 37 can limit the second sealing element 10 along the axial direction of the first tube 32, so that when the support seat 3 is inserted into the housing 1, the second sealing element 10 will not be displaced unexpectedly due to the friction between it and the inner wall of the liquid storage cavity 11. This ensures the installation accuracy of the second sealing element 10 during the installation process and the sealing performance at the connection position between the housing 1 and the support seat 3.

[0072] It should be noted that the first seal 6 and the second seal 10 should be made of materials that can produce elastic deformation, including but not limited to: silicone, rubber, etc.

[0073] In some embodiments, the connection method between the base 7 and the housing 1 includes, but is not limited to: screw connection, snap connection, adhesive connection, interference fit, etc.

[0074] For example, in some preferred embodiments, please refer to Figure 13 The base 7 and the housing 1 are connected by a snap-fit ​​connection. The base 7 is provided with a snap-fit ​​part 75, and the housing 1 is provided with a snap-fit ​​groove 14. The snap-fit ​​part 75 is snapped into the snap-fit ​​groove 14 to realize the snap-fit ​​connection between the base 7 and the housing 1.

[0075] In some embodiments, please refer to Figure 13 The base 7 is provided with a foolproof locking protrusion 76, and the housing 1 is provided with a foolproof groove 15. When the base 7 is connected to the housing 1, the foolproof locking protrusion 76 is accommodated in the foolproof groove 15, so that the base 7 and the housing 1 can be engaged in one go, which improves the accuracy of installation and reduces rework.

[0076] In some embodiments, please refer to Figure 13 The atomizer 100 also includes a third seal A1 and a fourth seal A2. The third seal A1 is located at the air outlet 12 and is sealed, and the fourth seal A2 is located at the air guide hole 73 and is sealed. The third seal A1 and the fourth seal A2 are used to isolate the atomizer 100 from the external environment and prevent foreign objects from entering the atomizer 100 during transportation and packaging.

[0077] This application also provides an atomizer 100, including a housing 1, a first tube 32, an atomizing component 2, and an air guide tube 13. The housing 1 defines a liquid storage chamber 11 for storing a liquid matrix and an air outlet 12 for providing aerosol output. The first tube 32 extends in the liquid storage chamber 11. The atomizing component 2 includes a second tube 21 and a heating element 23 located in the second tube 21. The second tube 21 is disposed in the hollow cavity 321 of the first tube 32. The first tube 32 provides support for the atomizing component 2. The air guide tube 13 is used to conduct aerosol. One end of the air guide tube 13 is connected to the air outlet 12, and the other end is connected to the second tube 21. The first tube 32 and the second tube 21 are separated by a first gap S1 extending axially along the first tube 32. The first gap S1 is filled with a first liquid storage element 4 and a second liquid storage element 5 spaced apart along the axial direction of the first tube 32. The first liquid storage element 4 connects the liquid storage chamber 11 and the atomizing component 2 to transfer the liquid matrix to the heating element 23. The second liquid storage element 5 is closer to the air outlet 12 than the first liquid storage element 4. Furthermore, the air guide tube 13 and the second tube 21 are separated by a third gap S3. The third gap S3 is used to construct a microchannel that keeps the interior of the second liquid storage element 5 and the second tube 21 connected. By using the first liquid storage element 4 and the second liquid storage element 5, which are spaced apart from each other within the first gap S1, when the liquid matrix overflows from the first liquid storage element 4 due to changes in external temperature or pressure, the second liquid storage element 5 can absorb and store the liquid matrix that overflows from the first liquid storage element 4 into the first gap S1. Since the first liquid storage element 4 connects the liquid storage chamber 11 and the atomizing component 2 and can transfer the liquid matrix, liquid matrix will also overflow from the atomizing component 2 under the influence of external temperature or pressure. The microchannel constructed by the third gap S3 allows the second liquid storage element 5 to absorb the liquid matrix that overflows from the atomizing component 2, thus preventing the liquid matrix from overflowing from the air outlet 12 into the external environment and affecting the user experience.

[0078] This application also provides 1000 embodiments of electronic atomizing devices; please refer to [link / reference]. Figure 16 The electronic atomizing device 1000 includes a power supply component and the aforementioned atomizer 100. The power supply component is used to connect to the atomizer 100 and supply power to the atomizer 100.

[0079] The power supply assembly has a positive electrode and a negative electrode. When the power supply assembly is connected to the atomizer 100, the positive electrode is electrically connected to a conductive element 8, and the negative electrode is electrically connected to another conductive element 8.

[0080] In some embodiments, the electronic atomizing device 1000 includes a mouthpiece 300, which is connected to the air outlet 12 of the atomizer 100. The mouthpiece 300 is used for a user to hold in their mouth so that the user can perform a suction action.

[0081] Understandably, the mouthpiece 300 can be detachably mounted on the atomizer 100, or integrated into the air outlet 12 of the atomizer 100, or integrated into the power supply assembly. Examples will not be given here.
