Description

Technical Field

[0001] This application belongs to the field of aerosol generation technology, and more specifically, relates to an atomizer and an electronic atomization device. Background Technology

[0002] Atomizers typically consist of a reservoir and a coil. The reservoir stores the atomizing medium, while the coil heats and atomizes the medium to generate an aerosol when powered on. To reduce leakage and improve the liquid supply rate from the reservoir to the coil, some atomizers incorporate a reservoir cotton between the reservoir and the coil. This cotton absorbs the atomizing medium in the reservoir and provides a continuous and stable supply to the coil. However, leakage can still occur during transportation or use, reducing the utilization rate of the atomizing medium and potentially causing blockages, thus affecting the vaping experience.

The bottom of the liquid-guiding outer layer, the liquid-retaining cotton, and the supporting inner tube are installed on the first seal. The main housing, the liquid-guiding outer layer, and the first seal together enclose the liquid-retaining cavity. The atomizing seat is installed on the side of the first seal away from the liquid-retaining cavity.

Detailed Implementation

[0040] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0041] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0042] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0043] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0044] As described in the background section, to reduce the liquid supply rate from the reservoir to the atomizing core and thus minimize leakage, some atomizers incorporate a reservoir cotton between the reservoir and the atomizing core. This cotton absorbs the atomizing medium from the reservoir and provides a continuous and stable liquid supply to the atomizing core. The reservoir cotton is designed to store a certain amount of atomizing medium to ensure its liquid supply function. However, during atomizer transportation or use, the atomizing medium at the atomizing core can still easily leak out, causing the reservoir cotton to absorb the medium from the reservoir. This not only reduces the amount of usable atomizing medium but also easily leads to leakage and blockage of the atomizer, affecting the vaping experience.

[0045] To address the aforementioned technical problems, this application provides an electronic atomizing device and atomizer. By providing a capillary channel 213 between the liquid storage chamber 101 and the atomizing core 300, the liquid storage chamber 101 is extended to serve as the liquid supply path for the atomizing core 300, thus delaying the atomizing medium from seeping into the atomizing core 300 and alleviating leakage at the atomizing core 300.

[0046] Please see Figure 1 First, the electronic atomizing device provided in the embodiments of this application will be described. The electronic atomizing device includes a power supply component and an atomizer. The power supply component is used to supply power to the atomizer, and the atomizer is used to store the atomizing medium. After being powered on, the atomizer can heat and atomize the atomizing medium to generate an aerosol.

[0047] Please see Figures 1 to 3 The atomizer provided in the embodiments of this application will now be described.

[0048] The atomizer has a liquid storage chamber 101, a liquid guiding assembly 200, and an atomizing core 300. The liquid guiding assembly 200 includes a liquid guiding outer layer 210, a supporting inner tube 220, and a liquid storage cotton 230. The atomizing core 300 is installed in the supporting inner tube 220, the liquid guiding outer layer 210 is sleeved outside the supporting inner tube 220, and the liquid storage cotton 230 is filled between the supporting inner tube 220 and the liquid guiding outer layer 210. The liquid guiding outer layer 210 has at least one layer of capillary channels 213. The channel 213 extends along the axial and circumferential directions of the liquid-conducting outer layer 210. The liquid-conducting outer layer 210 also has a first liquid outlet 2111 connecting the liquid storage cavity 101 and the capillary channel 213, and a plurality of second liquid outlets 2121 connecting the capillary channel 213 and the liquid storage cotton 230. The second liquid outlets 2121 are distributed at intervals along the axial direction of the liquid-conducting outer layer 210. The supporting inner tube 220 has a third liquid outlet 221 connecting the liquid storage cotton 230 and the atomizing core 300.

[0049] It should be noted that the outer liquid-conducting layer 210 has at least one layer of capillary channels 213, which means that the number of capillary channels 213 can be one layer or multiple layers. When the number of capillary channels 213 is multiple layers, each layer of capillary channels 213 is distributed radially at intervals within the outer liquid-conducting layer 210, and adjacent layers of capillary channels 213 can be interconnected through connecting holes.

[0050] The capillary channel 213 extends along the axial and circumferential directions of the liquid-conducting outer layer 210. The axial length of the capillary channel 213 can be designed according to the axial length of the liquid-conducting cotton 230. In addition, the capillary channel 213 can extend around the entire circumference of the liquid-conducting outer layer 210, or it can extend locally around the circumference of the liquid-conducting outer layer 210. Alternatively, multiple capillary channels 213 can be provided in the same layer, with each capillary channel 213 distributed around the circumference of the liquid-conducting outer layer 210.

[0051] It should be noted that the outer fluid-conducting layer 210 is sleeved outside the inner supporting tube 220. The cross-sections of the inner and outer peripheral walls of the outer fluid-conducting layer 210 can be closed shapes such as circles, polygons, and ellipses. The circumferential direction of the outer fluid-conducting layer 210 is the direction in which it surrounds the inner supporting tube 220; it can be a circular direction or other closed shapes. When the outer fluid-conducting layer 210 is cylindrical, its axial direction is the same as the cylindrical direction. When the cross-section of the outer fluid-conducting layer 210 is not circular, its axial direction is the direction in which one end face of the outer fluid-conducting layer 210 extends perpendicularly to the other end face.

[0052] When liquid is supplied to the atomizing core 300 through the liquid storage chamber 101, the atomizing medium in the liquid storage chamber 101 first enters the capillary channel 213 through the first liquid outlet 2111; then, the atomizing medium in the capillary channel 213 rises along the axial and circumferential directions of the outer liquid-conducting layer 210 to various parts of the capillary channel 213 through capillary action; then, the atomizing medium in the capillary channel 213 is drawn into different axial positions of the liquid storage cotton 230 through each of the second liquid outlet 2121; finally, the atomizing medium in the liquid storage cotton 230 is drawn into the atomizing core 300 through the third liquid outlet 221, and the atomizing core 300 is heated and atomized after being energized to generate an aerosol.

[0053] The atomizer in this embodiment of the application provides a capillary channel 213, a first liquid outlet 2111, and multiple second liquid outlets 2121 in the liquid-conducting outer layer 210. The first liquid outlet 2111 connects the liquid storage chamber 101 and the capillary channel 213. Each of the second liquid outlets 2121 is distributed along the axial direction of the liquid-conducting outer layer 210 and connects the capillary channel 213 and the liquid storage cotton 230. This allows the atomizing medium to enter the capillary channel 213 before entering the liquid storage cotton 230 from the liquid storage chamber 101, increasing the path of the atomizing medium from the liquid storage chamber 101 to the liquid storage cotton 230, which in turn increases the path of the atomizing medium to the atomizing core 300. This can delay the atomizing medium from seeping into the atomizing core 300 during transportation or use, thereby alleviating leakage at the atomizing core 300, increasing the usable amount of atomizing medium, improving the utilization rate of the atomizing medium, and reducing leakage and blockage.

[0054] In some embodiments, the inner support tube 220, the outer liquid-guiding layer 210, the liquid-retaining cotton 230, and the atomizing core 300 are all cylindrical and coaxially arranged. It is understood that in other embodiments of this application, the inner support tube 220, the outer liquid-guiding layer 210, the liquid-retaining cotton 230, and the atomizing core 300 may not be cylindrical; for example, their cross-sections may be elliptical, polygonal, or closed curves, and this is not a limiting factor.

[0055] In some embodiments, the central axis of the liquid-conducting outer layer 210 coincides with the central axis of the atomizer, and the main air passage of the atomizer is disposed through it along its axial direction. It can be understood that in other embodiments of this application, the central axis of the liquid-conducting outer layer 210 may also deviate from the central axis of the atomizer, or the central axis of the liquid-conducting outer layer 210 may also form an angle with the central axis of the atomizer.

[0056] In this application, the structure of the liquid-conducting outer layer 210 can be different. A detailed description is provided below using multiple tube bodies as examples. Other structural forms of the liquid-conducting outer layer 210 are illustrated at the end of the specification.

[0057] In some embodiments, the outer liquid-conducting layer 210 includes at least two tubes that are sequentially nested from the inside out. Adjacent tubes are spaced apart to form a capillary channel 213. A first liquid outlet 2111 is formed on the outer tube, and a second liquid outlet 2121 is formed on the inner tube. When the capillary channel 213 has multiple layers, the tubes between adjacent layers of capillary channels 213 are provided with connecting holes to connect the capillary channels 213 on both sides. In this embodiment, by using multiple tubes and forming annular capillary channels 213 with intervals between adjacent tubes, the climbing height of the atomizing medium in the capillary channel 213 can be controlled by controlling the gap between adjacent tubes. This reduces the manufacturing difficulty of the capillary channel 213, and the gap between adjacent tubes can be designed to be relatively smaller, resulting in a higher climbing height of the atomizing medium in the capillary channel 213.

[0058] For some specific embodiments, please refer to Figure 2 The outer liquid-conducting layer 210 includes two tubes, namely a first tube 211 and a second tube 212. The first tube 211 is sleeved over the second tube 212, and the first tube 211 and the second tube 212 form a capillary channel 213 at an interval. A first liquid discharge hole 2111 is formed in the first tube 211, and a second liquid discharge hole 2121 is formed in the second tube 212. The arrangement of the two tubes not only forms the capillary channel 213, but also has a simple structure and is easy to assemble.

[0059] In some embodiments, the capillary channel 213 extends around the liquid storage cotton 230. This prolongs the time it takes for the atomizing medium to fill the capillary channel 213, delays the time for the atomizing medium to penetrate into the atomizing core 300, and allows the liquid storage cotton 230 to be supplied with liquid at different circumferential positions, ensuring the uniformity of atomization of the atomizing core 300 in the circumferential direction. It is understood that in other embodiments of this application, the capillary channel 213 may also extend circumferentially around the liquid storage cotton 230, or multiple capillary channels 213 may be formed in the outer liquid guiding layer 210 at intervals around the liquid storage cotton 230; this is not a unique limitation.

[0060] In some embodiments, please refer to Figure 2 Both ends of the capillary channel 213 extend axially relative to the axial ends of the liquid storage cotton 230, meaning that the capillary channel 213 can cover the liquid storage cotton 230 axially, prolonging the time it takes for the atomizing medium to fill the capillary channel 213 and delaying the time it takes for the atomizing medium to penetrate into the atomizing core 300. It is understood that in other embodiments of this application, both ends of the capillary channel 213 may also be recessed relative to the axial ends of the liquid storage cotton 230, or one end of the capillary channel 213 may be recessed relative to one end of the liquid storage cotton 230; this is not a unique limitation.

[0061] In some embodiments, the capillary channel 213 has a first width along the radial direction of the outer liquid-conducting layer 210. The first height that the atomizing medium can climb in the capillary channel 213 is inversely related to the first width; that is, the smaller the first width, the greater the first height that the atomizing medium can rise; the larger the first width, the smaller the first height that the atomizing medium can rise. Specifically, when the first width of the capillary channel 213 is smaller, the capillary force of the atomizing medium in the capillary channel 213 is greater, and therefore the first height that the atomizing medium can climb in the capillary channel 213 is greater; when the first width of the capillary channel 213 is greater, the capillary force of the atomizing medium in the capillary channel 213 is smaller, and therefore the first height that the atomizing medium can climb in the capillary channel 213 is smaller.

[0062] In an embodiment where the outer liquid-conducting layer 210 includes a first tube 211 and a second tube 212, the inner diameter of the first tube 211 is set to 10.6 mm. Experiments are conducted using the outer diameters of the second tube 212 as examples of 9.6 mm, 9.8 mm, 10 mm, 10.2 mm, and 10.4 mm. Corresponding to different outer diameters of the second tube 212, the first widths are 0.5 mm, 0.4 mm, 0.3 mm, 0.2 mm, and 0.1 mm, respectively. The surface tension of the atomizing medium in the capillary channel 213 is assumed to be 0 in all structural cases. With a contact angle of 20 degrees and a contact strength of 0.45 N / m, the capillary forces obtained by the atomizing medium in the capillary channels 213 of the second tubes 212 with different outer diameters are 73.45477113 N, 91.81846391 N, 122.4246185 N, 183.6369278 N, and 367.2738556 N, respectively. Their corresponding first heights are 6.80704023, 8.508800288, 11.34506705, 17.01760058, and 34.03520115, respectively. Figure 10 This is a graph showing the relationship between the first width of the capillary channel 213 and the capillary force and the first height of the atomized medium in the capillary channel 213. The horizontal axis represents the first width in mm, and the vertical axes represent the capillary force and the first height, respectively. The upper line represents the relationship between the first width and the capillary force, and the lower line represents the relationship between the first width and the first height.

[0063] In this application, the first liquid outlet 2111 is formed in the liquid-conducting outer layer 210 and located at the bottom of the liquid storage cavity 101. In an embodiment including the first tube 211 and the second tube 212, please refer to... Figure 2 The first liquid outlet 2111 is formed in the first tube body 211 and located at the bottom of the liquid storage chamber 101. This arrangement facilitates the entry of the atomized medium in the liquid storage chamber 101 into the capillary channel 213 through the first liquid outlet 2111.

[0064] In some embodiments, there are multiple first liquid outlet holes 2111, and each first liquid outlet hole 2111 is distributed at intervals along the circumference of the liquid-conducting outer layer 210. The arrangement of multiple first liquid outlet holes 2111 allows the atomizing medium in the liquid storage chamber 101 to enter the capillary channel 213 at different positions along the circumference, improving the uniformity of the circumferential distribution of the atomizing medium in the capillary channel 213. It is understood that in other embodiments of this application, the number of first liquid outlet holes 2111 may also be one, and this is not a limiting factor.

[0065] In some embodiments, please refer to Figure 2 and Figure 3 The outer liquid-guiding layer 210 has multiple rows of second liquid-draining holes 2121 spaced apart along its axial direction. The second liquid-draining holes 2121 in the same row are spaced apart circumferentially along the outer liquid-guiding layer 210. Adjacent rows of second liquid-draining holes 2121 are staggered circumferentially along the outer liquid-guiding layer 210. This arrangement ensures that the outer liquid-guiding layer 210 has second liquid-draining holes 2121 distributed at different axial and circumferential positions, enabling liquid supply to the liquid-retaining cotton 230 at different axial and circumferential positions. This allows the liquid-retaining cotton 230 to retain more atomizing medium, ensuring a continuous and stable liquid supply to the atomizing core 300.

[0066] In some specific embodiments, the liquid-guiding outer layer 210 has three rows of second liquid-draining holes 2121 spaced apart along the axial direction. These three rows correspond to the axial middle position, the axial position near the top, and the axial position near the bottom of the liquid-retaining cotton 230, respectively. This facilitates the gradual penetration of the atomizing medium from these three positions into the axial positions of the liquid-retaining cotton 230. Understandably, in other embodiments, the liquid-guiding outer layer 210 may also have one, two, four, or more rows of second liquid-draining holes 2121. Of course, the second liquid-draining holes 2121 should not be too densely distributed along the axial direction, otherwise the capillary effect of the capillary channel 213 will be poor. Therefore, the number of rows of second liquid-draining holes 2121 is generally set according to actual needs.

[0067] In some specific embodiments, each row of second drainage holes 2121 includes two second drainage holes 2121 spaced 180 degrees apart circumferentially. Adjacent rows of second drainage holes 2121 are staggered 90 degrees circumferentially. This arrangement ensures that four second drainage holes 2121 are evenly distributed circumferentially in adjacent rows, with equal intervals between them, thus guaranteeing uniform circumferential liquid supply to the liquid storage cotton 230 by each drainage hole 2121. It is understood that in other embodiments of this application, each row of second drainage holes 2121 may also include one, three, or more second drainage holes 2121, and adjacent rows of second drainage holes 2121 may be staggered circumferentially by 30 degrees, 60 degrees, 120 degrees, 180 degrees, etc., without limitation. In addition, the second liquid outlet 2121 may not be arranged in separate rows, but may be irregularly distributed along the circumference and axial direction of the outer liquid guiding layer 210. This is not a unique limitation.

[0068] In practical applications, a first height can be designed based on the first width of the capillary channel 213, and then the position, size and number of the first liquid outlet 2111 that can be matched can be designed based on the first height, as well as the position, size and number of the second liquid outlet 2121 that can be matched, so as to provide a continuous and stable liquid supply to the atomizing core 300.

[0069] In some embodiments, please refer to Figure 4 Along the axial direction of the outer liquid-conducting layer 210, the minimum axial distance D1 between the second liquid-draining hole 2121 and the axial end face of the liquid-storing cotton 230 is greater than 1mm.

[0070] It should be noted that the outer liquid-conducting layer 210 has multiple second liquid outlet holes 2121 distributed along its axial direction, and the liquid storage cotton 230 has two axial end faces, namely the first axial end face 231 and the second axial end face 232. The minimum axial distance D1 between the second liquid outlet hole 2121 and the axial end face of the liquid storage cotton 230 refers to the minimum axial distance D1 between the second liquid outlet hole 2121 near the axial end face of the liquid storage cotton 230 and the corresponding axial end face. That is, the minimum axial distance D1 between the second liquid outlet hole 2121 near the first axial end face 231 and the first axial end face 231 is greater than 1 mm, and the minimum axial distance between the second liquid outlet hole 2121 near the second axial end face 232 and the second axial end face 232 is greater than 1 mm. Furthermore, the minimum axial distance D1 between the second liquid outlet 2121 and the first axial end face 231 refers to the minimum axial distance from any point in the second liquid outlet 2121 to the first axial end face 231, which is the axial distance from the point in the second liquid outlet 2121 closest to the first axial end face 231 to the first axial end face 231.

[0071] In this embodiment, by setting the minimum axial distance D1 between the second liquid outlet 2121 and the axial end face of the liquid storage cotton 230 to be greater than 1 mm, the atomizing medium flowing from the second liquid outlet 2121 to the liquid storage cotton 230 is prevented from flowing directly from the gap between the axial end face of the liquid storage cotton 230 and the wall of the atomizer to the atomizing core 300, thereby reducing the leakage of the atomizing core 300.

[0072] In some specific embodiments, the axial direction of the liquid-guiding outer layer 210 is parallel to the longitudinal direction of the atomizer. Along the axial direction of the liquid-guiding outer layer 210, the minimum axial distance D1 between the lowermost second liquid outlet 2121 and the lower end face of the liquid storage cotton 230 is greater than 1 mm, and the minimum axial distance D1 between the uppermost second liquid outlet 2121 and the upper end face of the liquid storage cotton 230 is also greater than 1 mm. The longitudinal direction of the atomizer is the direction of vertical extension from one end of the atomizer to the other, which is the height direction when the atomizer is placed vertically.

[0073] In some embodiments, please refer to Figure 2 The atomizer also includes a main housing 100 and a first sealing element 400. The main housing 100 has an inner cavity, an air outlet 105 communicating with the inner cavity, and a bottom opening communicating with the inner cavity. The first sealing element 400 is interference-fitted into the bottom opening of the main housing 100. The liquid guiding assembly 200 is installed in the inner cavity of the main housing 100. The opposite ends of the liquid guiding assembly 200 are respectively connected to the main housing 100 and the first sealing element 400. The main housing 100, the liquid guiding assembly 200, and the first sealing element 400 together enclose a liquid storage cavity 101.

[0074] In some embodiments, please refer to Figure 2The outer liquid-conducting layer 210 includes two tubes, namely a first tube 211 and a second tube 212. The first tube 211 is sleeved on the outside of the second tube 212. The first tube 211 and the second tube 212 form a capillary channel 213 at intervals. A first liquid outlet 2111 is formed in the first tube 211, and a second liquid outlet 2121 is formed in the second tube 212. The atomizer also includes a main housing 100, a first seal 400, and a second seal 500. The main housing 100 has an inner cavity, an air outlet 105 communicating with the inner cavity, and a bottom opening communicating with the inner cavity. The first seal 400 is interference-fitted to the bottom opening of the main housing 100. The liquid-conducting assembly 200 is installed in the inner cavity of the main housing 100. The opposite ends of the liquid-conducting assembly 200 are respectively connected to the main housing 100 and the first seal 400. The main housing 100, the liquid-conducting assembly 200, and the first seal 400 together form a liquid storage cavity 101. The bottom ends of the first tube 211, the second tube 212, the liquid storage cotton 230, and the supporting inner tube 220 are respectively installed on the first sealing member 400, forming a sealed connection between the first tube 211, the second tube 212, the liquid storage cotton 230, and the supporting inner tube 220 through the first sealing member 400; the top ends of the first tube 211 and the second tube 212 respectively abut against the second sealing member 500, forming a seal at the top end of the capillary channel 213 through the second sealing member 500. The first sealing member 400 has a first connection port 440 connecting the external atmosphere and the supporting inner tube 220, and the second sealing member 500 has a second connection port 510 connecting the supporting inner tube 220 and the air outlet 105. External air enters the inner support tube 220 through the first connection port 440, and enters the central channel of the atomizing core 300 from the bottom end of the inner support tube 220 to carry away the aerosol generated at the atomizing core 300, and enters the air outlet 105 through the second connection port 510 for the user to inhale.

[0075] In some embodiments, please refer to Figures 5 to 7The atomizer also includes a main housing 100 and a first sealing element 400. The first sealing element 400 is interference-fitted to the main housing 100. The bottom of the liquid guiding outer layer 210, the liquid storage cotton 230 and the support inner tube 220 are all installed on the first sealing element 400. The main housing 100, the liquid guiding outer layer 210 and the first sealing element 400 together form a liquid storage cavity 101. The first sealing element 400 has a sealing part 410, which is interference-fitted between the liquid guiding outer layer 210 and the support inner tube 220. In this embodiment, the bottom seal of the liquid-guiding outer layer 210 and the supporting inner tube 220 is achieved by sealing the liquid storage cavity 101 with the first sealing member 400. This eliminates the need for additional silicone parts to be inserted into the liquid-guiding outer layer 210 and the supporting inner tube 220 to form a seal, thus reducing the structural assembly cost of the silicone parts. At the same time, it eliminates the need to form an assembly groove in the first sealing member 400 to accommodate the bottom of the liquid-guiding outer layer 210, the liquid storage cotton 230 and the supporting inner tube 220. Furthermore, it eliminates the need to reserve a thick inner wall in the first sealing member 400 to ensure the secure installation of the liquid-guiding outer layer 210, the liquid storage cotton 230 and the supporting inner tube 220, while ensuring sufficient liquid space in the liquid storage cavity 101. This reduces the radial dimension of the first sealing member 400, thereby reducing the outer diameter of the entire atomizer and facilitating the miniaturization design of the atomizer. Furthermore, the first sealing element 400, the liquid-guiding outer layer 210, the liquid-retaining cotton 230, and the supporting inner tube 220 are all separate structures, but are assembled together, which can reduce the overall cost of the atomizer. It is understood that in other embodiments of this application, additional silicone components can also be provided to achieve the sealing of the liquid-guiding outer layer 210, the liquid-retaining cotton 230, and the supporting inner tube 220.

[0076] Specifically, the main housing 100 has an inner cavity, an air outlet 105 communicating with the inner cavity, and a bottom opening communicating with the inner cavity. The first seal 400 is interference-fitted to the bottom opening of the main housing 100.

[0077] For some specific embodiments, please refer to Figure 5 The outer peripheral surface of the first seal 400 is press-fitted against the inner peripheral surface of the main housing 100 to form a sealed connection between the first seal 400 and the main housing 100.

[0078] For some specific embodiments, please refer to Figure 5 and Figure 6A lower liquid groove 420 is formed on the side of the first sealing member 400 facing the liquid storage cavity 101. The lower liquid groove 420 is annular and surrounds the sealing part 410. The sidewall of the lower liquid groove 420 is located on the sealing part 410. The bottom end of the liquid guiding outer layer 210 abuts against the bottom wall of the lower liquid groove 420. The atomized medium in the liquid storage cavity 101 is guided into the lower liquid groove 420 and enters the capillary channel 213 from the lower liquid groove 420 through the first lower liquid hole 2111. The lower liquid groove 420 reduces the difficulty for the atomized medium in the liquid storage cavity 101 to enter the first lower liquid hole 2111.

[0079] Specifically, the top surface of the first seal 400 facing the liquid storage cavity 101 is also formed with a liquid guiding surface 430. The liquid guiding surface 430 extends obliquely from the top surface of the first seal 400 to the peripheral side wall of the lower liquid tank 420 to guide the atomizing medium to flow into the lower liquid tank 420.

[0080] In some embodiments, please refer to Figure 5 The atomizer also includes a main housing 100, a first seal 400, a second seal 500, a first sealing plug 800, and a second sealing plug 900. The first seal 400 and the second seal 500 are respectively installed on the main housing 100. The bottom ends of the liquid-guiding outer layer 210, the liquid storage cotton 230, and the supporting inner tube 220 are respectively installed on the first seal 400, and the top end of the liquid-guiding outer layer 210 is installed on the second seal 500. The first seal 400 has a first connection port 440 communicating with the supporting inner tube 220, and the second seal 500 has a second connection port 510 communicating with the supporting inner tube 220. The first sealing plug 800 is inserted into the first connection port 440 through the air inlet 104 of the atomizer, and the second sealing plug 900 is inserted into the second connection port 510 through the air outlet 105 of the atomizer. The first sealing plug 800 and the second sealing plug 900 are designed so that when the atomizer is in transport or storage, the first sealing plug 800 and the second sealing plug 900 can be inserted into the air inlet 104 and the air outlet 105 of the atomizer respectively into the inner support tube 220. This can prevent the atomizing medium from leaking into places without cotton during transport, thereby reducing the leakage of the atomizing medium and improving the utilization rate of the atomizing medium.

[0081] For some specific embodiments, please refer to Figure 5Along the axial direction, the inner diameter of the second connecting port 510 is larger in the middle and smaller at both ends, and the inner surface of the second connecting port 510 extends along a curve along the axial direction. This design not only guides the second sealing plug 900 into and out of the second connecting port 510, but also reduces the contact area between the second sealing plug 900 and the inner wall of the second connecting port 510, reducing the difficulty of inserting and removing the second sealing plug 900 while ensuring a seal. Similarly, the first connecting port 440 can also be designed to be larger in the middle and smaller at both ends, just like the second connecting port 510, or a guide surface can be provided at the bottom of the first connecting port 440 to guide the first sealing plug 800 into the first connecting port 440; no single limitation is made here.

[0082] In some embodiments, please refer to Figure 5 and Figure 7 The atomizer also includes a main housing 100, a first sealing element 400, and an atomizing seat 600. The first sealing element 400 is interference-fitted to the main housing 100. The bottom of the liquid guiding outer layer 210, the liquid storage cotton 230, and the supporting inner tube 220 are all installed on the first sealing element 400. The main housing 100, the liquid guiding outer layer 210, and the first sealing element 400 together enclose a liquid storage cavity 101. The atomizing seat 600 is installed on the side of the first sealing element 400 away from the liquid storage cavity 101. The atomizing seat 600 has a first liquid pocket cavity 102 and a second liquid pocket cavity 103 that are spaced apart along the axial direction. The first liquid-filled chamber 102 and the second liquid-filled chamber 103 are configured such that when the atomizing medium leaks from the atomizing core 300 through the first seal 400, it can be received and stored through the first liquid-filled chamber 102. When the first liquid-filled chamber 102 is full of atomizing medium, it can be received and stored through the second liquid-filled chamber 103. By using the double-layer liquid-filled chamber, the leakage of atomizing medium from the bottom of the atomizer can be reduced.

[0083] In some embodiments, please refer to Figure 6 and Figure 8 The first sealing element 400 has a first capillary groove 450 distributed on the side facing the first liquid cavity 102. That is, the first capillary groove 450 is distributed on the outer side of the bottom wall of the first sealing element 400. Through the first capillary groove 450, the atomizing medium leaked from the atomizing core 300 into the first sealing element 400 can be transported to various positions on the outer side of the bottom wall of the first sealing element 400 through capillary action, so as to facilitate the storage of the atomizing medium and the delivery of the atomizing medium to the first liquid cavity 102.

[0084] In some embodiments, please refer to Figure 6The bottom and side walls of the first liquid-holding cavity 102 are provided with second capillary grooves 611. These second capillary grooves 611 can transport the atomized medium within the first liquid-holding cavity 102 to various locations on the bottom and side walls of the first liquid-holding cavity 102, or transport the atomized medium into the first liquid-holding cavity 102 through the second capillary grooves 611. The ultimate purpose is to ensure that when there is significant leakage of the atomized medium, it can fill various locations within the first liquid-holding cavity 102, thus maintaining the liquid-holding capacity of the first liquid-holding cavity 102. In other embodiments, the second capillary grooves 611 may also be distributed on the bottom or side walls of the first liquid-holding cavity 102.

[0085] In some embodiments, please refer to Figure 6 The bottom wall, side wall, and top wall of the second liquid cavity 103 are provided with third capillary grooves 621. When the atomizing medium in the first liquid cavity 102 leaks, the atomizing medium can be transported to the second liquid cavity 103 through the third capillary grooves 621 on the top wall, side wall, and bottom wall of the second liquid cavity 103, ensuring that the atomizing medium fills all parts of the second liquid cavity 103 before leaking out. In other embodiments, the third capillary grooves 621 may also be distributed on the bottom and side walls, side walls and top walls, bottom and top walls, bottom wall, side walls, or top wall of the second liquid cavity 103.

[0086] In some embodiments, a first absorbent cotton is provided in the first liquid-collecting cavity 102. The first absorbent cotton can absorb and lock the atomized medium leaking from the first seal 400 into the first liquid-collecting cavity 102, thereby improving the liquid-collecting capacity of the first liquid-collecting cavity 102 and reducing the leakage of atomized medium in the first liquid-collecting cavity 102.

[0087] In some embodiments, please refer to Figure 5 The second liquid-absorbing chamber 103 is provided with a second absorbent cotton 1000. The second absorbent cotton 1000 can absorb and lock the atomized medium leaking from the first liquid-absorbing chamber 102 to the second liquid-absorbing chamber 103, thereby improving the liquid-absorbing capacity of the second liquid-absorbing chamber 103 and reducing the leakage of atomized medium in the second liquid-absorbing chamber 103.

[0088] For some specific embodiments, please refer to Figure 6 and Figure 8The first sealing element 400 has a first capillary groove 450 distributed on the side facing the first liquid-collecting cavity 102. The bottom and side walls of the first liquid-collecting cavity 102 have second capillary grooves 611, and the top wall of the second liquid-collecting cavity 103 has a third capillary groove 621. A second absorbent cotton 1000 is provided inside the second liquid-collecting cavity 103. The first capillary groove 450 and the second capillary groove 611 can transport the atomized medium leaking from the first sealing element 400 to the various walls of the first liquid-collecting cavity 102, ensuring the liquid-collecting capacity of the first liquid-collecting cavity 102. The third capillary groove 621 can transport the atomized medium leaking from the first liquid-collecting cavity 102 to the second liquid-collecting cavity 103. The second absorbent cotton 1000 can improve the liquid-collecting capacity of the second liquid-collecting cavity 103 and reduce the leakage of the atomized medium in the second liquid-collecting cavity 103.

[0089] In some embodiments, please refer to Figure 5 and Figure 6 The atomizing seat 600 includes an upper atomizing seat 610 and a lower atomizing seat 620. The upper atomizing seat 610 is connected to the first sealing member 400 and together they enclose a first liquid-filled cavity 102. The lower atomizing seat 620 is connected to the upper atomizing seat 610 and together they enclose a second liquid-filled cavity 103. By dividing the atomizing seat 600 into an upper atomizing seat 610 and a lower atomizing seat 620, the manufacturing difficulty of the first liquid-filled cavity 102 and the second liquid-filled cavity 103 can be reduced.

[0090] In some embodiments, please refer to Figure 5 and Figure 6 The atomizer also has an air intake channel (not shown in the figure), which passes through the lower atomizer 620 and the upper atomizer 610 in sequence. The first liquid pocket 102 surrounds the air intake channel, and the second liquid pocket 103 surrounds the air intake channel.

[0091] In some embodiments, please refer to Figure 6 The upper atomizing seat 610 has an opening facing the lower atomizing seat 620. The lower atomizing seat 620 is inserted into the mounting cavity. The atomizing seat 600 also includes a third sealing member 630, which is sleeved between the lower atomizing seat 620 and the upper atomizing seat 610. The third sealing member 630 is press-fitted between the outer peripheral wall of the lower atomizing seat 620 and the inner peripheral wall of the upper atomizing seat 610 to form a seal for the second liquid-collecting cavity 103.

[0092] In some embodiments, please refer to Figure 6The first sealing element 400 also has a liquid injection port 460 through which atomizing medium can be injected into the liquid storage chamber 101. The atomizing upper seat 610 has a first protrusion 612 protruding towards the liquid injection port 460. The atomizing upper seat 610 has a through groove 613 that passes through the atomizing upper seat 610 at the position corresponding to the first protrusion 612. The third sealing element 630 extends into the through groove 613 with a second protrusion 631. The third sealing element 630 is recessed on the side facing the atomizing lower seat 620 to form an installation groove 632. The atomizing lower seat 620 has a third protrusion 622 protruding at the position corresponding to the installation groove 632. During assembly, the first protrusion 612 is inserted into the injection port 460, the second protrusion 631 is inserted into the through groove 613 to seal the injection port 460, and the third protrusion 622 is inserted into the mounting groove 632 to position the atomizing lower seat 620 and the atomizing upper seat 610.

[0093] In some embodiments, please refer to Figure 2 and Figure 5 The atomizer also includes an electrode plate 700, which is installed on the side of the atomizing base 600 opposite to the first sealing member 400. The atomizing core 300 includes a liquid guiding member 310 and a heating member 320. The liquid guiding member 310 is cylindrical and installed in the inner support tube 220. The heating member 320 is attached to the inner peripheral wall of the liquid guiding member 310. The heating member 320 leads out multiple electrode feet 321, each of which passes through the first sealing member 400 and the atomizing base 600 to be electrically connected to the electrode plate 700. The electrode plate 700 is used to be electrically connected to the power supply component, so that the power supply component can supply power to the heating member 320, enabling the heating member 320 to generate heat to heat the atomizing medium.

[0094] In some embodiments, the liquid guiding element 310 is a liquid guiding cotton or a ceramic liquid guiding element 310.

[0095] In some embodiments, please refer to Figure 9 The electrode plate 700 has electrode rings 710 distributed radially at intervals, and each electrode foot 321 is electrically connected to each electrode ring 710.

[0096] In some embodiments, please refer to Figure 2 The inner support tube 220 is a metal tube. The inner support tube 220 is used to support the liquid storage cotton 230 and to guide the atomizing medium of the liquid storage cotton 230 to the atomizing core 300.

[0097] In some embodiments, the top end of the inner support tube 220 may be lower than the liquid storage cotton 230, or the top end of the inner support tube 220 may be higher than the liquid storage cotton 230, or the top end of the inner support tube 220 may be flush with the liquid storage cotton 230.

[0098] In some embodiments, the top end of the supporting inner tube 220 may be connected to the second seal 500, or the top end of the supporting inner tube 220 may not be connected to the second seal 500.

[0099] In some embodiments, please refer to Figure 1 and Figure 5 The atomizer also includes a decorative part 1100, which is fitted onto the bottom exterior of the main housing 100 to make the surface of the entire atomizer neat and beautiful.

[0100] In some other embodiments of this application, the liquid-guiding outer layer 210 can also be a one-piece molded part. In this case, the liquid-guiding outer layer 210 includes a liquid-guiding outer tube, a capillary channel 213 formed in the liquid-guiding outer tube, a first liquid outlet 2111 formed on the outer peripheral wall of the liquid-guiding outer tube, and a second liquid outlet 2121 formed on the inner peripheral wall of the liquid-guiding outer tube. That is, in this embodiment, the liquid-guiding outer layer 210 can be formed by one-time molding or one-time processing, which can reduce the number of structures in the liquid-guiding outer layer 210 and reduce the assembly difficulty of the liquid-guiding outer layer 210.

[0101] In this application, please refer to Figure 11 The atomizer has a liquid storage chamber 101, a liquid guiding assembly 200, and an atomizing core 300. The liquid guiding assembly 200 includes a liquid guiding outer layer 210, a supporting inner tube 220, and a liquid storage cotton 230. The atomizing core 300 is installed in the supporting inner tube 220, the liquid guiding outer layer 210 is sleeved on the outside of the supporting inner tube 220, and the liquid storage cotton 230 is filled between the supporting inner tube 220 and the liquid guiding outer layer 210. The liquid storage cotton 230 absorbs the atomizing medium in the liquid storage chamber 101 and provides a continuous and stable liquid supply to the atomizing core 300. With the above liquid supply structure, when the atomizer is placed horizontally or upside down, the atomizing medium in the liquid storage cotton 230 is prone to leak through the top of the liquid storage cotton 230, resulting in leakage.

[0102] To resolve the above technical issues, please refer to Figure 11 and Figure 12The atomizer also includes a liquid storage component 1200, which is installed inside the liquid-guiding outer layer 210 and abuts against the top surface of the liquid storage cotton 230. The liquid storage component 1200 has an axially penetrating connecting air passage 1210, which connects to the channel of the supporting inner tube 220. The outer peripheral wall of the liquid storage component 1200 forms a first liquid storage tank 1220 that is in liquid communication with the liquid storage cotton 230. The first liquid storage tank 1220 can adsorb and store the atomizing medium flowing between the liquid storage component 1200 and the liquid-guiding outer layer 210 through capillary action. The above configuration allows the atomizing medium in the storage cotton 230 to be absorbed and stored in the first storage tank 1220 when the atomizer is placed horizontally or upside down and flows between the storage element 1200 and the outer liquid guiding layer 210. When the atomizer is used upright, the atomizing medium in the storage cotton 230 is gradually consumed and the top of the storage cotton 230 gradually dries. Under the capillary action of the storage cotton 230 and the gravity of the atomizing medium, the atomizing medium in the first storage tank 1220 is gradually drawn back by the storage cotton 230, which not only reduces leakage but also improves the utilization rate of the atomizing medium.

[0103] In some embodiments, please refer to Figures 11 to 13 The outer peripheral wall of the liquid storage component 1200 has multiple first liquid storage tanks 1220, each extending circumferentially along the liquid storage component 1200 and spaced apart sequentially along its axial direction. Multiple connecting grooves 1230 are formed along the outer peripheral wall of the liquid storage component 1200, penetrating each first liquid storage tank 1220 along its axial direction to connect the various first liquid storage tanks 1220. This configuration improves the liquid storage capacity of the liquid storage component 1200, enabling it to store more atomizing medium and thus enhancing its leak-proof effect.

[0104] In some embodiments, please refer to Figures 11 to 13 The inner peripheral wall of the liquid storage component 1200 is provided with a second liquid storage tank 1240, and the end face of the liquid storage component 1200 facing the liquid storage cotton 230 is formed with a third liquid storage tank 1250. The third liquid storage tank 1250 is connected to the first liquid storage tank 1220 and the second liquid storage tank 1240 respectively. The third liquid storage tank 1250 realizes the connection between the liquid storage cotton 230 and the first liquid storage tank 1220, and also realizes the connection between the liquid storage cotton 230 and the second liquid storage tank 1240.

[0105] Optionally, the third liquid storage tank 1250 extends in segments along the circumference of the liquid storage component 1200.

[0106] Optionally, the second liquid storage tank 1240 extends along the axial direction of the liquid storage component 1200.

[0107] Alternatively, the liquid reservoir 1200 may be made of plastic, silicone or metal.

[0108] In some embodiments, please refer to Figure 11 The atomizer also includes a main housing 100, a first seal 400, and a second seal 500. The first seal 400 and the second seal 500 are respectively installed on the main housing 100. The bottom ends of the liquid-guiding outer layer 210, the liquid storage cotton 230, and the supporting inner tube 220 are respectively installed on the first seal 400, and the top end of the liquid-guiding outer layer 210 is installed on the second seal 500. The first seal 400 has a first connection port 440 communicating with the supporting inner tube 220, and the second seal 500 has a second connection port 510 communicating with the supporting inner tube 220. The liquid storage component 1200 is connected between the main housing 100 and the second seal 500, thereby improving the sealing connection between the liquid storage component 1200 and the main housing 100.

[0109] Specifically, a central tube 110 extends from the air outlet 105 of the main housing 100, and a second sealing member 500 is sleeved between the outer peripheral wall of the central tube 110 and the inner peripheral wall of the liquid storage member 1200 to form a sealed connection between the liquid storage member 1200 and the central tube 110.

[0110] A sealing ring 1300 abuts against the outer peripheral wall of the liquid reservoir 1200 and the outer liquid-conducting layer 210. Specifically, an annular groove 1260 is formed on the outer peripheral wall of the liquid reservoir 1200, and the sealing ring 1300 is housed within the annular groove 1260, abutting against the inner peripheral wall of the outer liquid-conducting layer 210. The top inner wall of the liquid reservoir 1200 corresponding to the annular groove 1260 abuts against the top surface of the outer liquid-conducting layer 210, and the top surface of the liquid reservoir 1200 abuts against the protruding rib 120 formed in the main housing 100.

[0111] In this application, please refer to Figure 11 A liquid storage cotton 230 is provided between the liquid storage chamber 101 and the atomizing core 300. The liquid storage cotton 230 absorbs the atomizing medium in the liquid storage chamber 101 and provides a continuous and stable liquid supply to the atomizing core 300. In order to prevent the atomizing medium from penetrating the ventilation channel, the above-mentioned liquid supply structure generally does not provide a ventilation channel in the liquid storage cotton 230, which would lead to problems such as poor ventilation and the absorption of burnt smell.

[0112] To resolve the above technical issues, please refer to Figure 11 and Figure 14The atomizer also includes a liquid storage component 1200, which is installed inside the liquid-guiding outer layer 210 and abuts against the top of the liquid storage cotton 230. The liquid storage component 1200 has an axially penetrating connecting air passage 1210, which connects to the channel of the supporting inner tube 220. The outer peripheral wall of the liquid storage component 1200 forms a first liquid storage tank 1220 that is in liquid communication with the liquid storage cotton 230. The first liquid storage tank 1220 can adsorb and store the atomizing medium flowing between the liquid storage component 1200 and the liquid-guiding outer layer 210 through capillary action. The outer peripheral wall of the liquid storage cotton 230 forms a ventilation groove 233, which is arranged axially through the liquid storage cotton 230. The combined design of the liquid storage component 1200 and the ventilation groove 233 ensures that the atomized medium leaking from the liquid storage cotton 230 is drawn into the liquid storage component 1200 without affecting the ventilation of the ventilation groove 233. This allows for improved ventilation through the ventilation groove 233, reducing the problem of scorching during suction.

[0113] Optionally, the number of ventilation slots 233 can be set according to actual needs, such as one, two or more.

[0114] In this application, please refer to Figure 11 and Figure 15 The liquid storage cotton 230 can be lower than the lowest liquid level of the liquid storage chamber 101. At this time, a liquid guiding groove 214 can be formed in the outer liquid guiding layer 210. The liquid guiding groove 214 extends from the lowest liquid level of the liquid storage chamber 101 to the liquid storage cotton 230. The liquid guiding groove 214 can guide the atomized medium in the liquid storage chamber 101 to the liquid storage cotton 230 through capillary action.

[0115] Optionally, the liquid guiding groove 214 extends along the axial direction of the liquid guiding outer layer 210. There can be multiple liquid guiding grooves 214, and each liquid guiding groove 214 is distributed at intervals along the circumference of the liquid guiding outer layer 210.

[0116] Optionally, the liquid guiding groove 214 may penetrate the bottom end face of the liquid guiding outer layer 210. Alternatively, when the bottom end face of the liquid guiding outer layer 210 is lower than the lowest liquid level of the liquid storage chamber 101, the liquid guiding groove 214 may not penetrate the bottom end face of the liquid guiding outer layer 210.

[0117] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
