[0056] Figures 1 to 3 illustrate an electronic atomization system 1 in the first embodiment of the present invention. The electronic atomization system 1 includes an atomization device 100 and a main unit 200 that is compatible with the atomization device 100. Among them, the atomization device 100 is used to atomize a liquid matrix after being powered on to generate an aerosol for the user to inhale. The atomization method of the atomization device 100 is not limited. For example, it may adopt one or several of atomization methods such as resistance heating, electromagnetic heating, infrared heating, chemical heating, ultrasonic atomization, plasma heating, etc. The main unit 200 can inject liquid into the atomization device 100 and / or charge the atomization device 100 after being connected to the atomization device 100.

[0057] Of course, in other embodiments, the electronic atomization system 1 may also include a main unit 200 and at least two atomizing devices 100 that are matched with the main unit 200, and the main unit 200 can simultaneously inject liquid and / or charge at least two atomizing devices 100.

[0058] The electronic atomization system 1 of this invention can be applied to the field of electronic cigarettes, as well as to fields such as medical or beauty treatments.

[0059] The atomizing device 100 and the main unit 200 can be combined in a detachable manner. The atomizing device 100 can be used in the following ways: (1) the user uses the atomizing device 100 alone, and the user can generate aerosol by atomizing a liquid matrix using the atomizing device 100; (2) the atomizing device 100 is attached to the main unit 200, and the main unit 200 injects liquid into the atomizing device 100; (3) the atomizing device 100 is attached to the main unit 200, and the main unit 200 charges the atomizing device 100; (4) the atomizing device 100 is attached to the main unit 200, and the main unit 200 injects liquid into the atomizing device 100 and charges it.

[0060] The atomizing device 100 can be inserted into or otherwise coupled to the host 200 for liquid injection and / or charging. In some embodiments, the host 200 has a receiving cavity 210 for accommodating at least a portion of the atomizing device 100, the atomizing device 100 being able to be at least partially inserted into the receiving cavity 210 for liquid injection and / or charging, and removed from the receiving cavity 210 after liquid injection and / or charging is completed.

[0061] One end of the receiving cavity 210 has an opening 211, through which the atomizing device 100 can be inserted into the receiving cavity 210.

[0062] In some embodiments, the atomizing device 100 may be cylindrical; correspondingly, the receiving cavity 210 for accommodating at least a portion of the atomizing device 100 may be cylindrical, or quasi-cylindrical, or other shapes, as long as the atomizing device 100 can be placed in the receiving cavity 210 to achieve liquid injection. The atomizing device 100 may have a shape and size similar to a cigarette, thereby allowing the user to obtain an experience similar to smoking a cigarette, and is small in size and easy to carry. Of course, in other embodiments, the shape of the atomizing device 100 is not limited, for example, it may also have various shapes such as elliptical cylinder, racetrack-shaped cylinder, square cylinder, polygonal cylinder, etc., and the receiving cavity 210 may also be various shapes adapted to the atomizing device 100.

[0063] The shape of the host 200 is not limited. For example, the host 200 can have various shapes such as racetrack-shaped column, elliptical column, cylindrical, square column, polygonal column, etc.

[0064] The main unit 200 includes a liquid supply module 202 and a power supply module 201, wherein the liquid supply module 202 is used to inject liquid into the atomizing device 100, and the power supply module 201 is used to charge the atomizing device 100. Of course, in other embodiments, the main unit 200 may only include the liquid supply module 202, or the main unit 200 may only include the power supply module 201.

[0065] The liquid supply module 202 includes a liquid storage chamber 24 for storing a liquid matrix and a first capillary liquid guiding structure 25 in fluid communication with the liquid storage chamber 24. The atomizing device 100 includes a second capillary liquid guiding structure 14. Both the first capillary liquid guiding structure 25 and the second capillary liquid guiding structure 14 can transport the liquid matrix through capillary force. When the atomizing device 100 and the main unit 200 are connected, the first capillary liquid guiding structure 25 and the second capillary liquid guiding structure 14 are in fluid communication, and the liquid storage chamber 24 is in fluid communication with the second capillary liquid guiding structure 14. In this way, the liquid matrix in the liquid storage chamber 24 can be transferred to the second capillary liquid guiding structure 14 through the capillary force of the first capillary liquid guiding structure 25, achieving the effect of automatic liquid injection. The liquid injection operation is convenient, the user experience is high, and no other liquid injection structure or additional operation is required.

[0066] Both the first capillary liquid-conducting structure 25 and the second capillary liquid-conducting structure 14 include capillary materials. As described herein, "capillary force" can refer to the ability of a capillary material to transport liquids via capillary action, preferably liquid matrices.

[0067] Both the first capillary liquid guiding structure 25 and the second capillary liquid guiding structure 14 include multiple capillary channels. When the atomizing device 100 and the main unit 200 are connected, the multiple capillary channels of the first capillary liquid guiding structure 25 are connected to the multiple capillary channels of the second capillary liquid guiding structure 14, thereby enabling fluid communication between the first capillary liquid guiding structure 25 and the second capillary liquid guiding structure 14. The liquid matrix can be transported from the liquid storage chamber 24 to the second capillary liquid guiding structure 14 through the capillary action of the capillary channels. When the second capillary liquid guiding structure 14 is saturated with liquid, the first capillary liquid guiding structure 25 can no longer transfer liquid matrix to the second capillary liquid guiding structure 14, achieving the effect of adaptively stopping the liquid supply when the atomizing device 100 is full. There will be no overfilling and leakage, and no additional electrical control structure is required. The structure is simple and the cost is low.

[0068] In this context, "saturation state" refers to the state where, regardless of the angle at which the electronic atomization system 1 is placed (e.g., upright, upside down, or tilted), the first capillary liquid-conducting structure 25 does not transfer the atomizing matrix to the second capillary liquid-conducting structure 14. This is the saturation state of the second capillary liquid-conducting structure 14. When the second capillary liquid-conducting structure 14 is in a saturated state, the content of the liquid matrix in the second capillary liquid-conducting structure 14 typically reaches its maximum value. Of course, factors such as temperature, environmental pressure, and changes in the atomizing matrix (e.g., atomizing matrices with different compositions or viscosities) can all affect the saturation state. The saturation state of the second capillary liquid-conducting structure 14 described herein refers to the saturation state of the second capillary liquid-conducting structure 14 when the electronic atomization system 1 is at a specific temperature and environmental pressure and using a specific atomizing matrix.

[0069] The capillary channel of the second capillary liquid guiding structure 14 also has a liquid storage function. The capillary channel of the second capillary liquid guiding structure 14 is configured to store an appropriate amount of liquid matrix for users to aspirate.

[0070] In some embodiments, the main unit 200 further includes a ventilation channel that connects the liquid storage chamber 24 to the outside atmosphere. As the liquid matrix in the liquid storage chamber 24 is consumed, a negative pressure will be generated in the liquid storage chamber 24, which can easily cause poor ventilation. By providing a ventilation channel, when the atomizing device 100 is connected to the main unit 200 and starts liquid injection, outside air can enter the liquid storage chamber 24 through the ventilation channel to at least partially balance the pressure in the liquid storage chamber 24 and ensure smooth liquid injection.

[0071] The liquid storage chamber 24 can usually adopt the following two ventilation methods: (1) the liquid injection channel and the ventilation channel are separate; (2) the liquid injection channel and the ventilation channel are combined. Among them, the liquid injection channel refers to the channel for transporting liquid matrix.

[0072] Ventilation methods that separate the injection channel and the ventilation channel generally include: 1) opening ventilation holes in the cavity wall of the liquid storage chamber 24 for ventilation. Of course, in order to reduce leakage from the ventilation holes, porous materials (such as waterproof and breathable membranes) can be filled or covered in the ventilation holes; 2) the liquid storage chamber 24 itself can deform. For example, the liquid storage chamber 24 includes flexible materials, and the pressure inside the liquid storage chamber 24 is balanced by the deformation of the liquid storage chamber 24 itself.

[0073] The combination of the injection channel and the ventilation channel specifically refers to utilizing the capillary channel of the first capillary liquid guiding structure 25 in an unsaturated state for ventilation. When the first capillary liquid guiding structure 25 is in a saturated state, the surface tension of the liquid will seal the capillary channel, thereby reducing leakage.

[0074] In some embodiments, the ventilation channel may include any space or gap in the fluid transmission path from the first capillary fluid guiding structure 25 to the second capillary fluid guiding structure 14, such as the gap formed between the first capillary fluid guiding structure 25 and other structures that cooperate with the first capillary fluid guiding structure 25 (e.g., the reservoir shell 21b and / or the support 27).

[0075] The capillary channels of the first capillary liquid-conducting structure 25 are configured to maintain a certain volume of liquid matrix in fluid contact with the reservoir 24. These capillary channels include microfluidic features configured to prevent air and liquid matrix from bypassing each other during the filling and emptying of the first capillary liquid-conducting structure 25. Through capillary action, the liquid matrix can be guided to the second capillary liquid-conducting structure 14, and air can be allowed to enter the reservoir 24 to at least partially balance the pressure within the reservoir 24, ensuring smooth liquid injection.

[0076] When the atomizing device 100 is connected to the main unit 200 and begins to inject liquid, the liquid matrix in the storage chamber 24 is guided by the first capillary liquid guiding structure 25 to the second capillary liquid guiding structure 14 of the atomizing device 100. The saturation of the first capillary liquid guiding structure 25 decreases, and the capillary channel when the first capillary liquid guiding structure 25 is unsaturated can be used for air exchange to balance the pressure in the storage chamber 24 and ensure smooth liquid injection.

[0077] When the second capillary liquid guiding structure 14 of the atomizing device 100 is saturated, the first capillary liquid guiding structure 25 can no longer transfer liquid matrix to the second capillary liquid guiding structure 14. The saturation of the first capillary liquid guiding structure 25 increases, and the surface tension of the liquid will seal the capillary channel. The liquid storage chamber 24 can no longer be ventilated through the capillary channel of the first capillary liquid guiding structure 25, thereby isolating the liquid storage chamber 24 from the atmosphere and reducing leakage.

[0078] The first capillary liquid guiding structure 25 includes at least one first liquid guiding element, and the second capillary liquid guiding structure 14 includes at least one second liquid guiding element. Each liquid guiding element has multiple capillary channels, through which the liquid matrix can be guided.

[0079] The liquid guiding element may comprise any suitable material or combination of materials capable of transporting the liquid matrix and also inert relative to the liquid matrix. The liquid guiding element must be adapted to allow the desired amount of liquid matrix to be delivered to the second capillary liquid guiding structure 14.

[0080] When the atomizing device 100 and the main unit 200 are connected, the first capillary liquid guiding structure 25 and the second capillary liquid guiding structure 14 can be in contact with each other and fluidly connected, or they can be fluidly connected with a small gap. The fluid connection between the first capillary liquid guiding structure 25 and the second capillary liquid guiding structure 14 with a small gap means that there is a small gap between the first capillary liquid guiding structure 25 and the second capillary liquid guiding structure 14, but this small gap allows the liquid films between the first capillary liquid guiding structure 25 and the second capillary liquid guiding structure 14 to contact, thereby enabling fluid connection between the first capillary liquid guiding structure 25 and the second capillary liquid guiding structure 14. Preferably, the first capillary liquid guiding structure 25 and the second capillary liquid guiding structure 14 can be fluidly connected by an interference fit, thus avoiding the adverse effects of manufacturing and assembly errors on the liquid guiding effect.

[0081] The first capillary fluid-conducting structure 25 and the second capillary fluid-conducting structure 14 may be fluidly connected at, but not limited to, their end faces, sides, or both. Preferably, the first capillary fluid-conducting structure 25 and the second capillary fluid-conducting structure 14 are at least fluidly connected on their sides. This side-connection allows for a larger fluid-conducting area and faster injection. Side-connection can be achieved by interlocking the first capillary fluid-conducting structure 25 and the second capillary fluid-conducting structure 14. Specifically, the first capillary fluid-conducting structure 25 may be fitted over at least a portion of the second capillary fluid-conducting structure 14, or the second capillary fluid-conducting structure 14 may be fitted over at least a portion of the first capillary fluid-conducting structure 25.

[0082] The fluid guiding element can have any suitable shape, preferably cylindrical or tubular.

[0083] The liquid guiding element comprises any suitable material and combination of materials capable of conveying the liquid matrix toward the atomizing device 100. Preferably, the selection of one or more materials for the liquid guiding element depends on the physical properties of the liquid matrix. Suitable materials for the liquid guiding element include capillary materials.

[0084] The capillary material preferably comprises a capillary bundle. For example, the capillary material may include multiple fibers or threads or other fine-pore tubes. The fibers or threads may be generally aligned to deliver liquid toward the atomizing device 100. Alternatively, the capillary material may include a sponge-like or foam-like material. The structure of the capillary material may form multiple pores or tubes through which the liquid matrix can be transported by capillary action.

[0085] Capillary materials can include any suitable material or combination of materials. For example, capillary materials can include at least one of the following: sponge or foam materials, ceramic-based or graphite-based materials in fibrous or sintered powder form, foamed metal or plastic materials, fibrous materials (e.g., made from virgin or pressed fibers (e.g., cellulose acetate fibers, polyester fibers, bonded polyolefin fibers, polyethylene fibers, polyester fibers, or polypropylene fibers, nylon fibers)), and ceramics. Generally, capillary materials can be made from one or more of ceramics, carbon, fabrics, or plastics. Capillary materials can possess any suitable capillary action and porosity for different liquid physical properties.

[0086] The capillary material is preferably a porous material that is inherently porous, but it does not necessarily have to be. This porous material includes, but is not limited to, cotton-like materials (e.g., natural cotton and / or synthetic cotton) or inorganic porous materials (e.g., ceramic materials such as alumina, glass fibers, etc.). Alternatively, the porous material may include a material having multiple fabricated pores to allow the liquid matrix to migrate into the atomizing device 100. The porous material may include hydrophilic materials to improve the distribution and diffusion of the liquid matrix. The porous material can have any suitable porosity to be used with different liquid physical properties. Liquid guides with different porosities can be used to accommodate different physical properties of the liquid matrix, such as density, viscosity, surface tension, and vapor pressure.

[0087] Preferably, the liquid guiding component is made of a cotton-like material, such as polymer-modified integrated cotton. Exemplarily, the cotton-like material includes one or a combination of several selected from pure cotton, flax, hemp, jute, cellulose fiber, Tencel fiber, cupro fiber, and chemical fibers. The polymer-modified integrated cotton material may include one or a combination of several selected from PA6, PET, PA66, PP, PE, and PTT, with a density of 0.02~10 g / cm³, for example, 0.02~3 g / cm³ or 0.02~0.5 g / cm³.

[0088] In other embodiments, the liquid guiding component may also include other materials with capillary channels, such as silicone, plastic, stainless steel, glass, etc., which can form microchannels with capillary forces. For example, multiple capillary microchannels can be formed on the liquid guiding component through microfabrication processes. These microchannels include micropores and / or microgrooves. The microgrooves may be disposed on the outer and / or inner and / or end faces of the liquid guiding component, while the micropores are disposed throughout the interior of the liquid guiding component.

[0089] By incorporating microchannels, the liquid guiding component is not limited to porous materials; it can also be made of non-porous materials such as silicone, plastic, glass, and metal, thus expanding the range of materials that can be selected. If the liquid guiding component is made of a non-porous material, multiple microchannels form multiple capillary channels. If the liquid guiding component is made of a porous material, the multiple capillary channels of the liquid guiding component include multiple microchannels and a porous structure formed by the porous material.

[0090] Along the transport direction of the liquid matrix, the capillary forces of the first capillary liquid guiding structure 25 and the second capillary liquid guiding structure 14 can be basically the same. Specifically, the capillary forces of the first capillary liquid guiding structure 25 and the second capillary liquid guiding structure 14 are basically the same, and the capillary forces of the first capillary liquid guiding structure 25 and the second capillary liquid guiding structure 14 are also basically the same.

[0091] Alternatively, the first capillary liquid guiding structure 25 and the second capillary liquid guiding structure 14 can also form multiple segments of capillary force, including the following situations:

[0092] (1) The capillary forces of the first capillary liquid guiding structure 25 are basically the same, and the capillary forces of the second capillary liquid guiding structure 14 are basically the same, but the capillary force of the first capillary liquid guiding structure 25 is greater than or less than the capillary force of the second capillary liquid guiding structure 14.

[0093] (2) The capillary forces of the first capillary liquid guiding structure 25 are basically the same, while the second capillary liquid guiding structure 14 forms multiple segments with different capillary forces.

[0094] (3) The first capillary liquid guiding structure 25 forms multiple segments with different capillary forces, while the capillary forces of the second capillary liquid guiding structure 14 are basically the same.

[0095] (4) The first capillary liquid guiding structure 25 forms multiple segments with different capillary forces, and the second capillary liquid guiding structure 14 forms multiple segments with different capillary forces.

[0096] The first capillary liquid guiding structure 25 forms multiple segments with different capillary forces, which may include the following situations: (1) the capillary force of a certain part or several parts of the first capillary liquid guiding structure 25 is larger or smaller. For example, the capillary force of the first capillary liquid guiding structure 25 first increases and then decreases or first decreases and then increases; (2) the capillary force of the multiple segments of the first capillary liquid guiding structure 25 gradually increases along the transport direction of the liquid matrix, that is, the closer to the second capillary liquid guiding structure 14, the greater the capillary force.

[0097] The second capillary liquid guiding structure 14 forms multiple segments with different capillary forces, which may include the following situations: (1) the capillary force of a certain part or several parts of the second capillary liquid guiding structure 14 is larger or smaller. For example, the capillary force of the second capillary liquid guiding structure 14 first increases and then decreases or first decreases and then increases; (2) the capillary force of the multiple segments of the second capillary liquid guiding structure 14 gradually increases along the transport direction of the liquid matrix, that is, the capillary force is greater the further away from the first capillary liquid guiding structure 25.

[0098] By employing a gradient liquid-conducting structure with varying capillary forces, the liquid matrix can be better guided from the part with weaker capillary forces to the part with stronger capillary forces, thus improving the liquid-conducting effect.

[0099] The formation of these multi-segment capillary forces is unrestricted. For example, the first capillary liquid-guiding structure 25 and / or the second capillary liquid-guiding structure 14 include multiple liquid-guiding elements, each with a different capillary force. Specifically, the first capillary liquid-guiding structure 25 includes multiple liquid-guiding elements, the capillary force of which gradually increases along the transport direction of the liquid matrix; and / or, the second capillary liquid-guiding structure 14 includes multiple liquid-guiding elements, the capillary force of which gradually increases along the transport direction of the liquid matrix. Generally, the multiple liquid-guiding elements can achieve different capillary forces by using different materials and / or having different densities.

[0100] The capillary force on the same liquid guiding component can be essentially uniform. Alternatively, multiple segments with varying capillary forces can be formed on the same liquid guiding component. For example, if the liquid guiding component is made of cotton-like material, different densities can be formed through compression or other methods, resulting in different capillary forces. Another example is by setting the cross-sectional area of ​​the microchannels on the liquid guiding component into several segments of different sizes, or by setting the cross-sectional area of ​​the microchannels to gradually decrease along the transport direction of the liquid matrix.

[0101] As shown in Figure 3, in this embodiment, the first capillary liquid guiding structure 25 includes a liquid guiding element 251, and the second capillary liquid guiding structure 14 includes a liquid guiding element 141. The capillary forces of the liquid guiding elements 251 and 141 can remain essentially constant along the transport direction of the liquid matrix, resulting in a simple structure, easy assembly and manufacturing, and low cost. The capillary force of the liquid guiding element 141 can be greater than that of the liquid guiding element 251, which is beneficial for guiding the liquid matrix better from the liquid guiding element 251 to the liquid guiding element 141.

[0102] Of course, in other embodiments, multiple segments of capillary forces of different sizes can be formed on the liquid guiding member 251 and / or the liquid guiding member 141 in any known manner to improve the liquid guiding effect.

[0103] As shown in Figures 2 to 5, the liquid supply module 202 and the power supply module 201 can be connected together in a detachable or non-detachable manner. For example, the liquid supply module 202 and the power supply module 201 can be connected in a non-detachable manner by a snap-fit ​​(non-detachable snap-fit), so that after the user assembles the liquid supply module 202 and the power supply module 201 together, they cannot be separated without damaging the structure. Alternatively, the liquid supply module 202 and the power supply module 201 can be connected in a detachable manner by a snap-fit ​​(detachable snap-fit) or by magnetic attraction, so that the user can repeatedly assemble or detach the liquid supply module 202 and the power supply module 201.

[0104] The power supply module 201 includes a power supply housing 21a and a battery 22 and a control circuit disposed in the power supply housing 21a. The power supply housing 21a may be formed with a cavity 215 and a receiving cavity 216, wherein the cavity 215 is used to receive at least a portion of the atomizing device 100, and the receiving cavity 216 is used to receive at least a portion of the liquid supply module 202.

[0105] In some embodiments, the power supply module 201 further includes at least two charging electrodes 23 disposed in the power supply housing 21a and electrically connected to the battery 22, through which the power supply module 201 charges the atomizing device 100. Correspondingly, the atomizing device 100 includes at least two conductive electrodes 111. When the atomizing device 100 and the main unit 200 are connected, the at least two charging electrodes 23 can respectively contact the at least two conductive electrodes 111 to conduct electricity, thereby enabling the main unit 200 to charge the atomizing device 100.

[0106] In some embodiments, the charging electrode 23 can be an electrode post, preferably an elastic electrode post. Each charging electrode 23 is at least partially located in the cavity 215, facilitating contact and conduction with the conductive electrode 111 of the atomizing device 100 inserted into the cavity 215. The axial direction of the charging electrode 23 can be perpendicular to the axial direction of the cavity 210. At least two charging electrodes 23 can be located on the same circumferential side of the cavity 210 and can be spaced apart axially in the cavity 210. Of course, in other embodiments, multiple charging electrodes 23 can also be located on different circumferential sides of the cavity 210. In other embodiments, the charging electrode 23 may also include other electrode connection structures such as electrode connecting pieces.

[0107] Understandably, in other embodiments, the location of the charging electrode 23 is not limited and it can be located anywhere that can contact the conductive electrode 111. For example, the charging electrode 23 can also be located at the end face of the accommodating cavity 210.

[0108] Understandably, in other embodiments, the power supply module 201 and the atomizing device 100 can also be charged wirelessly. In this way, the power supply module 201 does not need to be equipped with the charging electrode 23, and the atomizing device 100 does not need to be equipped with the conductive electrode 111. Of course, the electronic atomizing system 1 can also have both wired charging and wireless charging methods.

[0109] The liquid supply module 202 may include a liquid storage shell 21b, which has a liquid storage cavity 24 storing a liquid matrix and a container 243 communicating with the liquid storage cavity 24. The liquid storage shell 21b also has a liquid guiding channel 240 communicating with the liquid storage cavity 24 and the container 243. A first capillary liquid guiding structure 25 is disposed in the container 243 and is in fluid communication with the liquid storage cavity 24 through the liquid guiding channel 240.

[0110] Preferably, the liquid channel 240 is located at or near the bottom of the liquid storage chamber 24, so that the liquid matrix in the liquid storage chamber 24 can basically flow out through the liquid channel 240 under the action of gravity, thereby improving the utilization rate of the liquid matrix.

[0111] The liquid storage shell 21b may include a first shell 211b and a second shell 212b that cooperate with each other. The first shell 211b and the second shell 212b can be connected together in a detachable or non-detachable manner. The first shell 211b and the second shell 212b cooperate to define the liquid storage cavity 24 and the buffer cavity 242. Specifically, the first shell 211b is a frame shape with an opening on one side (lateral side). The interior of the frame of the first shell 211b is divided into two spaces by a partition wall 241. The second shell 212b covers the opening of the first shell 211b, so that the two spaces respectively form the liquid storage cavity 24 and the buffer cavity 242.

[0112] The second shell 212b defines the cavity 243 and the liquid channel 240. Specifically, the cavity 243 may extend downward from the upper end of the second shell 212b, but does not penetrate the bottom wall of the second shell 212b.

[0113] In some embodiments, the liquid supply module 202 further includes a bracket 27 disposed in the cavity 243, the bracket 27 being used to fix the first capillary liquid guiding structure 25 in the cavity 243. The bracket 27 can be detachably disposed in the cavity 243, thus allowing the first capillary liquid guiding structure 25 to be replaced and the liquid storage cavity 24 to be reused, reducing user operating costs. Of course, in other embodiments, the bracket 27 can also be non-detachably disposed in the cavity 243, eliminating the need for repeated disassembly and reassembly of the liquid supply module 202 by the user, reducing user operations and simplifying interaction.

[0114] Furthermore, the support 27 can also divide the cavity 243 into an upper liquid-collecting cavity 2431 and a liquid-guiding cavity 2432 communicating with the lower end of the liquid-collecting cavity 2431. The liquid-collecting cavity 2431 can be used to accommodate at least a portion of the atomizing device 100. The liquid-collecting cavity 2431 communicates with the cavity 215 to form a receiving cavity 210. The first capillary liquid guiding structure 25 can extend at least partially into the liquid-collecting cavity 2431 to facilitate fluid communication with the atomizing device 100 inserted into the liquid-collecting cavity 2431.

[0115] The liquid reservoir 21b is at least partially disposed in the receiving cavity 216. The receiving cavity 216 has an opening on one side, through which the liquid reservoir 21b can be inserted into the receiving cavity 216. A portion of the liquid reservoir 21b protrudes from the power supply housing 21a through the opening of the receiving cavity 216. That is, the liquid reservoir 21b and the power supply housing 21a together form the outer shell 21 of the main unit 200.

[0116] Of course, in other embodiments, the power supply housing 21a may also include two parts, which can be connected together in a separable, rotatable, or sliding manner, thereby enabling the opening of the receiving cavity 216 to be opened or closed. After opening the receiving cavity 216, the liquid supply module 202 is inserted, and then the opening of the receiving cavity 216 is closed, completely concealing the liquid supply module 202 within the power supply module 201. In this way, the power supply housing 21a forms the outer shell 21 of the main unit 200.

[0117] The main unit 200 is configured with two mutually perpendicular X, Y, and Z directions. The axis of the accommodating cavity 210 can be parallel to the Z direction. The battery 22 and the liquid storage cavity 24 can be arranged vertically along the Z direction within the outer casing 21.

[0118] In this embodiment, the host 200 has a longitudinally elongated cross-section (e.g., a racetrack circle, rectangle, ellipse, etc.), with the X direction of the host 200 being the length direction along its cross-section and the Y direction being the width direction along its cross-section. The power supply housing 21a has an opening on one side in the X direction, through which the liquid storage housing 21b can be inserted into the receiving cavity 216.

[0119] The cavity 215 has a first cavity 2151 and a second cavity 2152 arranged sequentially in the Z direction, wherein the first cavity 2151 communicates with the opening 211. The first cavity 2151 is open on one side in the X direction, that is, the cross-section of the first cavity 2151 is not closed. The cross-section of the second cavity 2152 is closed.

[0120] In some embodiments, the liquid storage shell 21b may also form a buffer cavity 242. This buffer cavity 242 may be located below the liquid storage cavity 24 and is used to store liquid matrix leaking from the liquid storage cavity 24, thereby reducing leakage. The buffer cavity 242 may also be in fluid communication with the first capillary liquid guiding structure 25, allowing the liquid matrix in the buffer cavity 242 to flow back to the first capillary liquid guiding structure 25 for reuse, thus improving the utilization rate of the liquid matrix.

[0121] In some embodiments, the buffer cavity 242 may be located directly below the liquid storage cavity 24, and the buffer cavity 242 and the liquid storage cavity 24 may be separated by a partition wall 241. Of course, in other embodiments, the liquid storage shell 21b may not have a buffer cavity 242. Specifically, the liquid storage shell 21b may not have a partition wall 241, which can increase the liquid storage space of the liquid storage cavity 24.

[0122] The fluid guiding component 251 can be partially inserted into the fluid guiding component 141 to achieve fluid communication with it; that is, the outer surface of the fluid guiding component 251 is in fluid communication with the inner surface of the fluid guiding component 141. The outer surface of the fluid guiding component 251 and the inner surface of the fluid guiding component 141 can be in contact with each other or a small gap can be left, as long as fluid communication is maintained between them. Preferably, the outer surface of the fluid guiding component 251 and the inner surface of the fluid guiding component 141 are in close contact using an interference fit to ensure reliable fluid communication.

[0123] Considering that the liquid guide 251 is made of flexible cotton-like material, it is not easy to insert into the atomizing device 100. The main unit 200 may also include a support member 26 disposed in the housing 21 for supporting the liquid guide 251, so as to prevent the liquid guide 251 from bending and being difficult to insert into the liquid guide 141.

[0124] The liquid guiding member 251 can be tubular (e.g., cylindrical), and the support member 26 passes through the liquid guiding member 251. The end of the support member 26 can protrude from the liquid guiding member 251, or it can be flush with the end face of the liquid guiding member 251, so as to facilitate the insertion of the liquid guiding member 251 into the liquid guiding member 141.

[0125] The lower ends of both the liquid guiding member 251 and the support member 26 can be fixed to the bottom wall 213 of the outer casing 21. In some embodiments, an annular boss 2434 protrudes from the bottom wall 213, and the lower end of the support member 26 can be fixed to the annular boss 2434 by riveting or other means. The lower end of the liquid guiding member 251 is sleeved on the annular boss 2434, and the upper end of the liquid guiding member 251 extends into the liquid collecting cavity 2431.

[0126] The support member 26 is made of a rigid material. In some embodiments, the support member 26 can be a porous ceramic, and the porous structure of the support member 26 can also guide liquid, which is beneficial to improving the liquid guiding effect. Of course, in other embodiments, the support member 26 can also be made of a non-porous material (such as metal or plastic), and the liquid can be guided by the gap between the support member 26 and the liquid guiding member 251, or the support member 26 can not participate in the liquid guiding at all.

[0127] In some embodiments, the support member 26 may include a support rod 261 passing through the liquid guide member 251 and a support head 262 disposed at the upper end of the support rod 261 and extending out of the liquid guide member 251. The outer diameter of the support head 262 is larger than the outer diameter of the support rod 261 and larger than the inner diameter of the liquid guide member 251. The lower end face of the support head 262 abuts against the upper end face of the liquid guide member 251, thereby fixing the liquid guide member 251 to the liquid storage shell 21b and preventing the liquid guide member 251 from being pulled out when the atomizing device 100 is pulled out. The support rod 261 and the support head 262 may be integrally formed; or, the support rod 261 and the support head 262 may be formed separately and then assembled together. In this case, the materials of the support rod 261 and the support head 262 may be the same or different.

[0128] It should be noted that the main unit 200 in this invention can be configured for single use or reusable use; it can be entirely non-removable or partially removable. If the main unit 200 adopts a single-use structure, the liquid matrix in the liquid storage chamber 24 or the battery 22 can be directly replaced after its power is depleted. If a reusable structure is adopted, the battery 22 is a rechargeable battery, and the liquid storage chamber 24 is a liquid-fillable or replaceable structure. When the liquid matrix in the liquid storage chamber 24 is nearly depleted or completely depleted, liquid can be added to the liquid storage chamber 24 or the liquid storage chamber 24 can be directly replaced to achieve the purpose of reuse.

[0129] As shown in Figures 3 and 6, the atomizing device 100 further includes a housing 11 and a battery cell 12 and an atomizing core 15 disposed within the housing 11. The atomizing core 15 is in fluid communication with the second capillary liquid guiding structure 14 and is electrically connected to the battery cell 12, for atomizing the liquid matrix stored in the second capillary liquid guiding structure 14 after being energized. At least two conductive electrodes 111 are electrically connected to the battery cell 12 to enable charging of the battery cell 12.

[0130] In some embodiments, the atomizing core 15 includes a conductive material that can convert electrical energy into heat energy by utilizing the resistive heating effect generated when an electric current passes through the conductive material. The specific structure of the atomizing core 15 is not limited.

[0131] In some embodiments, the atomizing core 15 may consist only of a conductive material that contacts at least a portion of the liquid guiding member 141 to atomize the liquid matrix on the liquid guiding member 141 after energization. The specific shape of the atomizing core 15 is not limited; for example, it may be a mesh, array, or fabric formed from conductive filaments or conductive sheets, or a heating film formed by screen printing or deposition. The liquid guiding member 141 includes a liquid guiding body 1412 and an atomizing portion 1411, and the atomizing core 15 may be disposed on the inner wall surface of the atomizing portion 1411. Of course, in other embodiments, the atomizing core 15 may also be disposed at other locations on the atomizing portion 1411; for example, the atomizing core 15 may be disposed on the end face of the atomizing portion 1411, or it may be disposed on both the end face and the inner wall surface of the atomizing portion 1411.

[0132] In other embodiments, the atomizing core 15 may also include a liquid-conducting material and a conductive material. For example, the atomizing core 15 includes a liquid-conducting material (e.g., a liquid-conducting material made of porous materials such as porous ceramics or cotton) and a conductive element (e.g., a metal conductive wire, a metal conductive sheet, or a heating film) disposed on the liquid-conducting material. The shape of the liquid-conducting material is not limited; for example, it can be various shapes such as tubular, rod-shaped, sheet-shaped, or bowl-shaped.

[0133] Of course, in other embodiments, the atomizing core 15 may also adopt other atomizing structures, which may employ one or more of the following atomizing methods: resistance heating, electromagnetic heating, infrared heating, chemical heating, ultrasonic atomization, plasma heating, etc.

[0134] One end of the outer shell 11 has an air inlet 110, through which the user can inhale. The liquid guide 141 can be tubular (e.g., cylindrical), and an airflow channel 140 is formed through the liquid guide 141. The aerosol generated by the atomizing core 15 after atomizing the liquid matrix can be output to the air inlet 110 through the airflow channel 140 for the user to inhale.

[0135] Furthermore, the airflow channel 140 can also be used as a liquid injection channel. The liquid guide 251 can be inserted into the airflow channel 140 through the air intake 110 and fluidly communicate with the inner wall surface of the liquid guide 141, thereby injecting liquid into the liquid guide 141. In this way, it is possible to avoid opening an additional liquid injection channel on the atomizing device 100.

[0136] The atomizing device 100 is connected to the main unit 200 in an inverted manner, that is, the atomizing device 100 is connected to the main unit 200 through the inhalation end where its inhalation port 110 is located. When the atomizing device 100 is used for inhalation, its inhalation port 110 faces upward, and the liquid matrix at the distal end of the liquid guiding member 141 (the end away from the atomizing part 1411) will flow towards the atomizing part 1411 under the action of gravity and capillary force, and the liquid matrix at the distal end will be consumed first. However, when the atomizing device 100 is inserted into the main unit 200 in an inverted manner for liquid filling, the inhalation port 110 faces downward, the distal end of the liquid guiding member 141 faces downward and the proximal end (the end closer to the atomizing part 1411) faces upward. During liquid filling, the distal end of the liquid guiding member 141 requires less force to overcome gravity and can be replenished first.

[0137] The liquid guiding body 1412 and the atomizing part 1411 can be arranged coaxially in sequence, with the atomizing part 1411 located at the end of the liquid guiding body 1412 furthest from the air intake 110. This allows for a greater distance between the atomizing core 15 and the air intake 110, enabling the aerosol generated after atomization by the atomizing core 15 to be effectively cooled before reaching the air intake 110, thereby achieving a suitable suction temperature. Of course, in other embodiments, the atomizing part 1411 can also be located at other positions on the liquid guiding member 141, such as in the middle or lower middle part of the liquid guiding member 141.

[0138] The outer diameter of the liquid guiding body 1412 can be adapted to the inner diameter of the outer shell 11, thereby fixing the liquid guiding component 141 in the outer shell 11 and allowing the liquid guiding component 141 to have a large liquid storage capacity. The outer diameter of the atomizing part 1411 can be less than or equal to the inner diameter of the outer shell 11.

[0139] In some embodiments, the atomizing device 100 further includes an airflow sensor 13 and a control circuit disposed in the housing 11. The airflow sensor 13 is electrically connected to the control circuit and fluidly communicates with the airflow channel 140. The airflow sensor 13 can detect changes in the suction airflow within the airflow channel 140, and the control circuit can control whether to activate the atomizing device 100 based on the signal emitted by the airflow sensor 13.

[0140] At least two conductive electrodes 111 may be at least partially disposed on the housing 11 of the atomizing device 100, facilitating contact and conduction with the at least two charging electrodes 23 of the main unit 200. Furthermore, the at least two conductive electrodes 111 may form part of the housing 11, thus eliminating the need for additional electrode elements, saving costs, and simplifying the structure of the atomizing device 100, allowing for a more aesthetically pleasing and compact design. Of course, in other embodiments, the at least two conductive electrodes 111 may also include additional electrode pillars or electrode sheets. Additionally, the at least two conductive electrodes 111 may not be disposed on the side of the housing 11; for example, they may be disposed at the bottom of the housing 11 or other locations.

[0141] In this embodiment, at least two conductive electrodes 111 include a first conductive electrode 113 and a second conductive electrode 114. The atomizing device 100 also includes an electrode assembly 16 disposed in the housing 11. The two poles of the atomizing core 15 are electrically connected to the first conductive electrode 113 and the electrode assembly 16, respectively. The first conductive electrode 113 and the electrode assembly 16 are then electrically connected to the battery cell 12, thereby achieving circuit conduction between the atomizing core 15 and the battery cell 12. At the same time, the first conductive electrode 113 and the second conductive electrode 114 are respectively connected to the battery cell 12 to achieve charging of the battery cell 12. That is, the first conductive electrode 113 serves as both the charging electrode of the battery cell 12 and the electrode of the atomizing core 15, thereby reducing the number of electrodes required.

[0142] In some embodiments, the atomizing device 100 further includes an insulating isolator 112, which is at least partially disposed between the first conductive electrode 113 and the second conductive electrode 114, insulatingly separating the first conductive electrode 113 and the second conductive electrode 114. It is understood that the insulating isolator 112 is also at least partially disposed on the housing 11, and may constitute a part of the housing 11.

[0143] In some embodiments, the liquid storage capacity in the atomizing device 100 is greater than or equal to (preferably greater than) the power of the battery cell 12. In this way, when the power of the battery cell 12 is depleted, the liquid matrix in the atomizing device 100 is not depleted or is just depleted, thus avoiding dry burning.

[0144] When the atomizing core 15 includes a liquid guide, the liquid storage capacity within the atomizing device 100 is the sum of the liquid storage capacity of the second capillary liquid guiding structure 14 and the liquid storage capacity of the liquid guide. When the atomizing core 15 does not include a liquid guide, the liquid storage capacity within the atomizing device 100 is the liquid storage capacity of the second capillary liquid guiding structure 14.

[0145] Furthermore, the liquid replenishment rate of the atomizing device 100 is faster than or equal to the charging rate of the battery cell 12. Otherwise, when the user removes the atomizing device 100, the liquid level in the atomizing device 100 may be less than the battery cell's charge, resulting in condensation during vaping. In other words, during each charging cycle, the mass of liquid matrix replenished to the atomizing device 100 by the main unit 200 is greater than or equal to the mass of liquid matrix consumed by the charging power. The comparison between the liquid replenishment rate and the charging rate can also be evaluated by the number of puffs that can be taken with the replenished liquid volume and the available power.

[0146] When the electronic atomization system 1 is placed vertically, the liquid matrix flows upward from the first capillary liquid guiding structure 25 to the second capillary liquid guiding structure 14. During this flow, it needs to overcome gravity, resulting in a slower liquid replenishment rate. In some embodiments, the liquid replenishment rate of the electronic atomization system 1 when placed vertically is 18% to 40% faster than the charging rate, and the liquid replenishment rate of the electronic atomization system 1 when placed horizontally is 136% to 180% faster than the charging rate.

[0147] The comparison between the liquid storage capacity in the atomizing device 100 and the charge of the battery 12 can be evaluated using the number of puffs. The number of puffs that the liquid matrix in the atomizing device 100 can provide is greater than or equal to the number of puffs that the battery can provide. For example, if each puff is set to 2 seconds of vaping and 8 seconds of rest, consuming approximately 8.5 mg of liquid matrix, the nominal charge of the battery 12 is 190 mAh, with a power of 10 W, allowing for 125 puffs; while the atomizing device 100, when fully filled with approximately 2g of liquid, can provide approximately 250 puffs. Therefore, when the atomizing device 100 is fully filled, the charge of the battery 12 will be depleted before the liquid matrix in the atomizing device 100. When the battery 12 is depleted, the atomizing device 100 has consumed approximately 1.1g of liquid matrix in 125 puffs. After the main unit 200 replenishes the atomizing device 100 with approximately 1.1g of liquid matrix, the second capillary liquid guiding structure 14 becomes saturated, thus automatically stopping the liquid supply.

[0148] Tables 1 and 2 show the comparison results of replenishment speed and charging speed when the electronic atomization system 1 uses two liquid matrices with different viscosities (lemon-lime with a viscosity of approximately 120-140 mPa·s and blueberry-raspberry with a viscosity of approximately 200 mPa·s). The electronic atomization system 1 is placed vertically, and the nominal capacity of the battery cell 12 is 190 mAh with a power of 10 W.

[0149] Table 1: Comparison of replenishment rate and charging rate of lemon and lime (viscosity approx. 120~140 mPa.s)

[0150]

[0151] Table 2: Comparison of replenishment rate and charging rate for blueberry and tart raspberry (viscosity approx. 200 mPa·s)

[0152]

[0153] As can be seen from Tables 1 and 2, when the electronic atomization system 1 uses two liquid matrices of different viscosities, during the entire replenishment and charging process, the amount of liquid replenished by the host 200 to the atomization device 100 that can be used for the number of aspirations is greater than the amount of electricity replenished, that is, the replenishment speed is faster than the charging speed.

[0154] Tables 3 and 4 show a comparison of the liquid consumption of the atomizing device 100 when the battery is fully charged versus the liquid replenishment amount when the battery is fully charged, using two liquid matrices of different viscosities (lemon lime and blueberry raspberry). The liquid consumption of the battery 12 was measured at an atomization power of 10 W.

[0155] Table 3: Lemon and Lime (viscosity approximately 120~140 mPa.s)

[0156]

[0157] Table 4: Blueberry and Raspberry (viscosity approx. 200 mPa.s)

[0158]

[0159] As can be seen from Tables 3 and 4, when the electronic atomization system 1 uses two liquid matrices of different viscosities, the liquid consumption of the fully charged atomizing device 100 is less than the liquid replenishment when the atomizing device 100 is fully charged.

[0160] It should be noted that the atomizing device 100 in this invention can be either entirely non-removable or partially removable.

[0161] In some embodiments, the atomizing device 100 may include an atomizer 101 and a power supply 102. The atomizer 101 is primarily used to store a liquid matrix and atomize it upon power application. Accordingly, the atomizer 101 includes a second capillary liquid guiding structure 14 and an atomizing core 15. The power supply 102 is primarily used to supply power to the power supply 102 and control the opening and closing of the entire atomizing device 100. Accordingly, the power supply 102 includes a battery 12, a control circuit, and an airflow sensor 13. The atomizer 101 and the power supply 102 can be connected together in a detachable or non-detachable manner.

[0162] Figures 7 and 8 illustrate the electronic atomization system 1 in the second embodiment of the present invention. The main difference between this system and the first embodiment is that the first capillary liquid guiding structure 25 in this embodiment includes two liquid guiding elements 252 and 251, and the second capillary liquid guiding structure 14 includes three liquid guiding elements 142, 143, and 144. When the atomizing device 100 and the main unit 200 are connected, the liquid matrix in the storage chamber 24 can be sequentially transferred through liquid guiding elements 252, 251, 142, and 143, and finally to liquid guiding element 144.

[0163] Among them, the capillary force of liquid guiding component 251 is greater than that of liquid guiding component 252, so the liquid matrix can be better guided from liquid guiding component 252 with lower capillary force to liquid guiding component 251 with higher capillary force. The capillary forces of liquid guiding components 142, 143, and 144 increase in sequence, so the liquid matrix can be better guided from liquid guiding component 142 with lower capillary force to liquid guiding components 143 and 144 with higher capillary force.

[0164] Both liquid-guiding components 252 and 251 can be made of cotton-like materials, resulting in good liquid-guiding performance. Liquid-guiding components 252 and 251 can be made of different materials and / or have different densities, so that the capillary force of liquid-guiding component 251 is greater than that of liquid-guiding component 252. Generally, if the two liquid-guiding components are made of the same material, the liquid-guiding component with the higher density will generate a larger capillary force. In some embodiments, liquid-guiding component 252 can be made of disordered cotton (e.g., PE+PP integrated cotton) with a density of 0.04~0.1 g / cm³. 3 The liquid guiding component 251 can be made of disordered cotton (e.g., PE+PP integrated cotton) with a density of 0.16~0.2 g / cm³. 3 .

[0165] Liquid guiding components 142, 143, and 144 can also be made of cotton-like materials, which offer good liquid guiding performance and a large liquid storage capacity. In some embodiments, liquid guiding component 142 can be made of disordered cotton (e.g., PA+PET integrated cotton) with a density of approximately 0.12~0.16 g / cm³. Liquid guiding component 143 can be made of disordered cotton (e.g., PA+PET integrated cotton) with a density of 0.16~0.2 g / cm³. 3 Left and right. The fluid guiding component 144 can be made of cotton material such as flax + cupro fiber.

[0166] It should be noted that the density of the liquid guiding component 142 does not necessarily need to be greater than the density of the liquid guiding component 251. For example, the density of the liquid guiding component 251 is 0.2 g / cm³, and the density of the liquid guiding component 142 is 0.14 g / cm³. The density of the liquid guiding component 142 can be less than, equal to, or greater than the density of the liquid guiding component 251. When the liquid matrix in the liquid guiding component 142 is exhausted or nearly exhausted, the liquid matrix in the liquid guiding component 251 can still be guided to the liquid guiding component 142 through capillary action and wettability.

[0167] The support 27 is disposed in the cavity 243 for fixing the liquid guide 252 and the liquid guide 251 in the cavity 243. In some embodiments, the support 27 may include a tubular portion 271, a cylindrical portion 273, and at least one connecting portion 272 connecting the tubular portion 271 and the cylindrical portion 273.

[0168] The tubular portion 271 is disposed in the liquid-collecting cavity 2431, and the outer wall surface of the tubular portion 271 is tightly fitted and fixed to the inner wall surface of the liquid-collecting cavity 2431. The shape of the inner wall surface of the tubular portion 271 can be adapted to the atomizing device 100 to fix the atomizing device 100 in the circumferential direction.

[0169] There may be two or more connecting portions 272, with at least two connecting portions 272 spaced apart circumferentially on the tubular portion 271. This helps reduce resistance when the atomizing device 100 is inserted into the support 27 and when the support 27 is inserted into the cavity 243. Furthermore, since at least two connecting portions 272 are not closed circumferentially, the upper end of the liquid guide 251 can communicate with the liquid collection cavity 2431, allowing the liquid matrix stored in the liquid collection cavity 2431 to be absorbed by the liquid guide 251 and reused. Of course, in other embodiments, there may be only one connecting portion 272, which can be tubular or arc-shaped.

[0170] A cylindrical portion 273 is disposed within a liquid guiding cavity 2432, and its outer wall surface is tightly fitted and fixed to the inner wall surface of the liquid guiding cavity 2432. The cylindrical portion 273 is open at the lower end, through which the liquid guiding component 252 can be inserted. A through hole 2730 is provided on the top wall of the cylindrical portion 273 for the liquid guiding component 252 to pass through.

[0171] In some embodiments, the cross-sectional area of ​​the liquid-collecting cavity 2431 is larger than that of the liquid-guiding cavity 2432, such that a stepped surface 2433 is formed at the junction of the liquid-collecting cavity 2431 and the liquid-guiding cavity 2432. The upper end face of the cylindrical portion 273 may be approximately flush with the stepped surface 2433, or it may not be flush. The larger cross-sectional area of ​​the liquid-collecting cavity 2431 helps to reduce the resistance when the cylindrical portion 273 is inserted into the liquid-guiding cavity 2432 via the liquid-collecting cavity 2431. Of course, in other embodiments, the cross-sectional area of ​​the liquid-collecting cavity 2431 and the cross-sectional area of ​​the liquid-guiding cavity 2432 may also be equal.

[0172] In some embodiments, a plurality of support bosses 2435 protrude upward from the bottom wall surface of the liquid guiding cavity 2432, which support the cylindrical portion 273 and the liquid guiding member 251. The plurality of support bosses 2435 may be spaced apart circumferentially around the liquid guiding cavity 2432. The plurality of support bosses 2435 may surround the annular boss 2434 and be spaced apart from the outer wall surface of the annular boss 2434. This structure allows a liquid storage space 2430 to be formed at the bottom of the cavity 243, which is generally an annular space defined between the inner wall surface of the liquid guiding cavity 2432 and the outer wall surface of the liquid guiding member 251. The liquid storage space 2430 can store leaked liquid, and the stored leaked liquid can be transferred to the atomizing device 100 via the liquid guiding member 251 for reuse.

[0173] In addition, a communication port 2436 is provided on the side wall of the liquid storage space 2430 to connect the liquid storage space 2430 with the buffer chamber 242, so that the leaked liquid stored in the buffer chamber 242 can also flow into the liquid storage space 2430 for reuse.

[0174] In some embodiments, a sealing ring 275 may also be fitted over the cylindrical portion 273. The sealing ring 275 is located between the liquid guiding channel 240 and the liquid collecting cavity 2431, which helps to improve the sealing between the outer wall surface of the cylindrical portion 273 and the inner wall surface of the liquid guiding cavity 2432, and prevents the liquid matrix flowing out of the liquid storage cavity 24 from the liquid guiding channel 240 from leaking into the liquid collecting cavity 2431.

[0175] In some embodiments, a sealing sleeve 276 may be fitted over the lower end of the cylindrical portion 273, and the cylindrical portion 273 abuts against the support boss 2435 through the sealing sleeve 276. The sealing sleeve 276 covers the lower opening of the cylindrical portion 273, thereby sealing the liquid guide 252 within the space defined by the sealing sleeve 276 and the cylindrical portion 273, reducing leakage of liquid guide 252 downwards. Both the sealing sleeve 276 and the sealing ring 275 may be made of elastic sealing materials such as silicone.

[0176] In some embodiments, the top wall of the cylindrical portion 273 may also protrude downward to form a plurality of limiting protrusions 274. These limiting protrusions 274 can limit the position of the upper end face and the outer side face of the liquid guide 252, thereby fixing the liquid guide 252 between the sealing sleeve 276 and the cylindrical portion 273. By providing the limiting protrusions 274, a space is formed between the liquid guide 252 and the cylindrical portion 273, thereby allowing space for the liquid guide 252 to absorb liquid and expand, and preventing leakage caused by excessive compression of the liquid guide 252.

[0177] Liquid guiding components 142, 143, and 144 can be arranged sequentially in the axial direction and are fluidly connected at their end faces. Specifically, liquid guiding components 142, 143, and 144 can be arranged coaxially in sequence and abut against each other at their end faces. The atomizing core 15 can be disposed on the inner wall surface of the liquid guiding component 144.

[0178] Of course, in other embodiments, the liquid guiding element 142 and the liquid guiding element 143 may be arranged sequentially in the axial direction, and the liquid guiding element 144 may be disposed in the end of the liquid guiding element 143 away from the liquid guiding element 142 and in fluid communication with the inner wall surface of the liquid guiding element 142.

[0179] Figure 9 illustrates the electronic atomization system 1 in the third embodiment of the present invention. Similar to the second embodiment described above, the first capillary liquid guiding structure 25 in this embodiment also includes two liquid guiding elements 252 and 251, and the second capillary liquid guiding structure 14 includes three liquid guiding elements 142, 143, and 144. When the atomizing device 100 and the main unit 200 are connected, the liquid matrix in the liquid storage chamber 24 can be sequentially transferred through the liquid guiding elements 252, 251, 142, and 143 and finally to the liquid guiding element 144.

[0180] Unlike the second embodiment described above, the liquid guiding element 251 and the liquid guiding element 142 are fluidly connected only at their end faces. Specifically, the upper end face of the liquid guiding element 251 is in contact with or has a small gap with the lower end face of the liquid guiding element 142, thus maintaining fluid communication. The advantage of this liquid guiding structure is that no friction is generated between the liquid guiding element 251 and the liquid guiding element 142 when the atomizing device 100 is pulled out, making it easier to pull out.

[0181] Figures 10 and 11 illustrate the electronic atomization system 1 in the fourth embodiment of the present invention. Similar to the second embodiment described above, the first capillary liquid guiding structure 25 in this embodiment also includes two liquid guiding elements 252 and 251, and the second capillary liquid guiding structure 14 includes three liquid guiding elements 142, 143, and 144. When the atomizing device 100 and the main unit 200 are connected, the liquid matrix in the liquid storage chamber 24 can be sequentially transferred through the liquid guiding elements 252, 251, 142, and 143 and finally to the liquid guiding element 144.

[0182] Unlike the second embodiment described above, the liquid guiding component 251 and the liquid guiding component 142 are in fluid communication at both their side and end faces. The contact area between the liquid guiding component 251 and the liquid guiding component 142 is larger, resulting in a faster liquid guiding speed.

[0183] Specifically, the liquid guiding member 251 may include a rod portion 2514 and a sleeve portion 2515. The sleeve portion 2515 is cylindrical and has a through hole formed therein. The liquid guiding member 142 can be at least partially inserted into the through hole. The inner side surface of the sleeve portion 2515 is in fluid communication with the outer side surface of the liquid guiding member 142, and the bottom wall surface of the sleeve portion 2515 is in fluid communication with the lower end surface of the liquid guiding member 142. Of course, in other embodiments, only the inner side surface of the sleeve portion 2515 may be in fluid communication with the outer side surface of the liquid guiding member 142, or only the bottom wall surface of the sleeve portion 2515 may be in fluid communication with the lower end surface of the liquid guiding member 142.

[0184] The rod portion 2514 can be tubular (e.g., cylindrical), and the support member 26 passes through the rod portion 2514 to support it. The lower end of the rod portion 2514 is fitted onto the annular boss 2434. The liquid guiding member 252 is fitted onto the outside of the rod portion 2514, so that the outer surface of the rod portion 2514 is in fluid communication with the inner surface of the liquid guiding member 252.

[0185] The sleeve portion 2515 can extend upward from the upper end of the rod portion 2514. The outer diameter and inner diameter of the sleeve portion 2515 are larger than the outer diameter and inner diameter of the rod portion 2514, respectively. The sleeve portion 2515 can be sleeved on the outside of the liquid guiding member 142, so that the inner surface of the sleeve portion 2515 is in fluid communication with the outer surface of the liquid guiding member 142.

[0186] The housing 11 of the atomizing device 100 may include a housing body 115 and a mouthpiece sleeve 116 detachably disposed at one end of the housing body 115. An air inlet 110 is formed on the mouthpiece sleeve 116. The mouthpiece sleeve 116 can be fitted over the liquid guide 142 and conceal the liquid guide 142 inside, allowing the user to inhale through the air inlet 110 on the mouthpiece sleeve 116.

[0187] When the atomizing device 100 needs to be filled with liquid and charged, the mouthpiece sleeve 116 can be removed first, and then the atomizing device 100 can be inserted into the main unit 200.

[0188] The nozzle sleeve 116 and the housing body 115 can be sleeved together and fixed. In some embodiments, the nozzle sleeve 116 may include a nozzle portion 1161 and a fitting portion 1162. The nozzle portion 1161 and the fitting portion 1162 may be coaxially arranged, but are not limited to being coaxially arranged. An air intake 110 is formed at the end of the nozzle portion 1161 away from the nozzle portion 1161.

[0189] The insert portion 1162 can be inserted into the shell body 115. The outer diameter of the nozzle portion 1161 can be the same as the outer diameter of the shell body 115. Of course, in other embodiments, the outer diameter of the nozzle portion 1161 can also be smaller or larger than the outer diameter of the shell body 115.

[0190] The liquid guiding component 142 includes a liquid guiding portion 1421 disposed in the nozzle sleeve 116. The inner diameter of the nozzle portion 1161 can be equal to the inner diameter of the fitting portion 1162 and approximately equal to the outer diameter of the liquid guiding portion 1421, making it easier to process and manufacture.

[0191] In some embodiments, the liquid guiding member 142 may further include a flange portion 1422, which is disposed at one end of the liquid guiding member 1421 near the liquid guiding member 143, and the outer diameter of the flange portion 1422 is larger than the outer diameter of the liquid guiding member 1421. The outer diameter of the flange portion 1422 is equal to the outer diameter of the liquid guiding member 143 and is adapted to the inner diameter of the housing body 115 (including equal to, slightly larger than, or slightly smaller than). The liquid guiding member 142 is in fluid communication with the end face of the liquid guiding member 143 through the end face of the flange portion 1422, resulting in a larger liquid guiding area and better liquid guiding effect. Of course, in other embodiments, the liquid guiding member 142 may not include the flange portion 1422.

[0192] Figure 12 illustrates the electronic atomization system 1 in the fifth embodiment of the present invention. Similar to the second embodiment described above, the first capillary liquid guiding structure 25 in this embodiment also includes two liquid guiding elements 252 and 251, and the second capillary liquid guiding structure 14 includes three liquid guiding elements 142, 143, and 144. When the atomizing device 100 and the main unit 200 are connected, the liquid matrix in the liquid storage chamber 24 can be sequentially transferred through the liquid guiding elements 252, 251, 142, and 143 and finally to the liquid guiding element 144.

[0193] Unlike the second embodiment described above, the liquid guiding member 143 and the liquid guiding member 144 are in fluid communication at their side surfaces. Specifically, the liquid guiding member 144 is disposed in the end of the liquid guiding member 143 away from the liquid guiding member 142, and the outer wall surface of the liquid guiding member 144 is in fluid communication with the inner wall surface of the liquid guiding member 143.

[0194] Furthermore, the difference between this embodiment and the above embodiments is that the host 200 in this embodiment does not have a buffer cavity, thereby allowing the liquid storage cavity 24 to have a larger liquid storage space.

[0195] Figures 13 and 14 show the liquid supply module 202 of the host 200 in the sixth embodiment of the present invention. The main difference between it and the second embodiment is that the liquid guiding component 251 in this embodiment is rigid, and for example, it can be made of porous materials such as porous ceramics.

[0196] Since the fluid guide 251 is rigid, it does not require a supporting component, thus simplifying the parts, reducing costs, and making installation easier.

[0197] The liquid guiding element 251 can be either a hollow or solid column. When the liquid guiding element 251 is hollow, its upper end is preferably closed, which facilitates its insertion into the atomizing device 100. The lower end of the liquid guiding element 251 has an opening, allowing it to be fitted onto the protrusion 2437 at the bottom of the liquid storage shell 21b.

[0198] In some embodiments, the multiple capillary channels of the liquid guiding member 251 include multiple microgrooves 2510 formed on the outer surface of the liquid guiding member 251 by processes such as microfabrication. The microgrooves 2510 have a larger cross-sectional area than the pores of the porous structure of the liquid guiding member 251 itself, which can improve the liquid guiding rate of the liquid guiding member 251. The microgrooves 2510 can extend along the axial direction of the liquid guiding member 251, which is beneficial for shortening the liquid guiding path. The multiple microgrooves 2510 are evenly spaced circumferentially on the liquid guiding member 251.

[0199] In some embodiments, the liquid guiding member 251 includes a first rod portion 2511 and a second rod portion 2512 arranged sequentially along the axial direction. The first rod portion 2511 is in fluid communication with the second capillary liquid guiding structure 14, and the second rod portion 2512 is in fluid communication with the liquid guiding member 252.

[0200] In some embodiments, the outer diameter of the first rod portion 2511 may be smaller than the outer diameter of the second rod portion 2512, thus forming a stepped surface 2513 at the upper end of the second rod portion 2512. The stepped surface 2513 can abut against the top wall of the cylindrical portion 273 of the support 27, thereby pressing and fixing the second rod portion 2512 between the top wall of the cylindrical portion 273 and the bottom wall of the liquid storage shell 21b.

[0201] In some embodiments, a vent 2731 is also provided through the top wall of the cylindrical portion 273, which connects the liquid-collecting cavity 2431 to the liquid-guiding component 252. Outside air in the liquid-collecting cavity 2431 can enter the liquid-guiding component 252 through the vent 2731, flow through the porous gaps of the unsaturated liquid-guiding component 252, and enter the liquid storage cavity 24 through the liquid-guiding channel 240 to balance the pressure in the liquid storage cavity 24.

[0202] By setting the ventilation hole 2731, the ventilation capacity of the liquid storage chamber 24 can be improved.

[0203] In addition, the liquid-collecting cavity 2431 in this embodiment is provided with a porous liquid-collecting component 277. The porous liquid-collecting component 277 can be made of porous materials such as cotton or porous ceramics. It can absorb the leaked liquid in the liquid-collecting cavity 2431 through capillary force, thereby reducing leakage. The porous liquid-collecting component 277 is preferably made of cotton, which can absorb and store more liquid matrix.

[0204] The main unit 200 can form a three-level leak-proof system to prevent the liquid matrix in the storage chamber 24 from leaking to the outside. Specific details are as follows:

[0205] Level 1 leak prevention: When the liquid guiding component 252 is saturated, its porous gaps are filled with liquid matrix, and the porous ventilation channels are closed, achieving leak prevention in normal environments (such as room temperature);

[0206] Secondary leak prevention: In harsh environments (such as rapid changes in temperature or air pressure), the liquid matrix in the storage chamber 24 leaks into the buffer chamber 242, which stores the leaked liquid. When the atomizing device 100 is inserted into the main unit 200, the liquid guide 251 is in direct contact with the liquid matrix in the buffer chamber 242, and the liquid guide 251 will preferentially absorb the liquid matrix in the buffer chamber 242, so the liquid matrix in the buffer chamber 242 can be utilized.

[0207] Three-level leak prevention: When the environment is extremely harsh, the liquid matrix in the liquid storage chamber 24 will leak into the liquid collection chamber 2431 and transfer to the porous liquid collection component 277.

[0208] Figure 15 shows the liquid supply module 202 of the host 200 in the seventh embodiment of the present invention. The main difference between this embodiment and the above embodiment is that the liquid supply module 202 in this embodiment includes a porous material 2732 (e.g., a waterproof and breathable membrane) that is sealed in the ventilation hole 2731. In this way, the liquid matrix will not leak out from the ventilation hole 2731, and the leakage prevention effect is better.

[0209] Figure 16 shows the electronic atomization system 1 in the eighth embodiment of the present invention. The main difference between it and the above embodiments is that the host 200 in this embodiment only has a liquid supply module 202 and no power supply module. Thus, there is no need to set up a space for setting up a power supply module in the outer shell 21, so that the liquid storage chamber 24 has a larger liquid storage space.

[0210] The liquid storage chamber 24 can be either user-fillable or non-fillable.

[0211] The outer casing 21 may or may not contain a buffer cavity 242.

[0212] Figure 17 shows the liquid supply module 202 of the host 200 in the ninth embodiment of the present invention. The main difference between this module and the above embodiment is that the liquid storage cavity 24 in this embodiment is provided with a porous liquid storage component 244 and the liquid guiding channel 240 is provided with a liquid guiding component 245, which can further improve the leak-proof effect of the liquid storage cavity 24.

[0213] The porous liquid storage component 244 can be made of porous materials such as cotton or porous ceramics. The porous structure of the porous liquid storage component 244 helps to store the liquid matrix, which is beneficial to reducing leakage.

[0214] Preferably, the porous liquid storage component 244 is made of cotton-like material, which allows for a large liquid storage capacity. The porous liquid storage component 244 can be made of a material with high porosity, thereby enabling it to store more liquid matrix. Furthermore, the relatively high porosity and relatively low density of the porous liquid storage component 244 facilitate the guiding of the liquid matrix within it to the liquid guiding component 245, which has a greater capillary force.

[0215] Preferably, the capillary force of the liquid guiding element 245 is greater than that of the porous liquid storage element 244, but less than that of the liquid guiding element 252. The liquid guiding element 245 is preferably made of cotton-like material, but other porous materials such as porous ceramics can also be used.

[0216] The porous liquid storage component 244, liquid guiding component 245, liquid guiding component 252, and liquid guiding component 251 are all connected in sequence by contact or by leaving small gaps, which improves the leak-proof effect.

[0217] Of course, in other embodiments, the liquid supply module 202 may not include the porous liquid storage element 244 or the liquid guiding element 245.

[0218] Figure 18 shows the liquid supply module 202 of the host 200 in the tenth embodiment of the present invention. The main difference between it and the above embodiment is that the liquid storage shell 21b in this embodiment does not have a buffer cavity, so the liquid storage cavity 24 has a larger liquid storage space.

[0219] The liquid storage chamber 24 is in fluid communication with the liquid guiding component 252 through the liquid guiding channel 240. The liquid guiding channel 240 can be located at or near the bottom of the liquid storage chamber 24, so that the liquid matrix in the liquid storage chamber 24 can basically flow out through the liquid guiding channel 240 under the action of gravity, thereby improving the utilization rate of the liquid matrix.

[0220] The liquid supply module 202 in this embodiment also includes a connecting channel 246, which connects the liquid guiding chamber 2432 to the liquid storage chamber 24. That is, the connecting channel 246 connects the liquid guiding member 252 to the liquid storage chamber 24, so that the air flowing in the porous gaps of the liquid guiding member 252 can enter the liquid storage chamber 24 through the connecting channel 246.

[0221] The connecting channel 246 is located above the liquid guiding channel 240. It may be partially formed on the second shell 212b of the liquid storage shell 21b and partially formed on the side wall of the cylindrical portion 273 of the support 27.

[0222] The cross-sectional area of ​​the liquid guiding channel 240 is larger than that of the connecting channel 246, and the liquid guiding channel 240 can be directly fluidly connected to the liquid guiding component 251. During liquid injection, the liquid matrix in the liquid storage chamber 24 preferentially flows to the liquid guiding component 251 through the liquid guiding channel 240, while the connecting channel 246 mainly realizes the ventilation of the liquid storage chamber 24, and the ventilation effect is better.

[0223] Of course, the ventilation channel in this embodiment may also include ventilation hole 2731. The structure of ventilation hole 2731 can be referred to the relevant description above, and will not be repeated here.

[0224] Figure 19 shows the host 200 in the eleventh embodiment of the present invention. The main difference between this embodiment and the previous embodiments is that the liquid supply module 202 and the power supply module 201 are non-detachably connected via a non-detachable snap-fit ​​(inverted snap). This avoids the risk of the liquid supply module 202 separating from the power supply module 201 in the event of a drop, and reduces user operations, eliminating the need for repeated assembly and disassembly of the liquid supply module 202, thus simplifying the interaction.

[0225] Specifically, at least one buckle 214b protrudes from the outer surface of the liquid storage shell 21b, and at least one slot 214a is formed on the cavity wall of the receiving cavity 216 of the power supply shell 21a, which engages with the at least one buckle 214b. When the liquid supply module 202 is inserted into the receiving cavity 216, the buckle 214b engages with the slot 214a, thereby fixing the liquid supply module 202 in the power supply module 201. Without damaging the structure of the liquid supply module 202 and / or the power supply module 201, the liquid supply module 202 cannot or is very difficult to remove from the power supply module 201.

[0226] Furthermore, in this embodiment, there are two inverted buckles 214b, which are symmetrically arranged on the upper and lower sides of the liquid storage shell 21b, respectively; correspondingly, there are also two slots 214a.

[0227] Of course, in other embodiments, a groove may be formed on the outer side of the liquid storage shell 21b, and an undercut may be formed on the inner side of the shell 21.

[0228] In other embodiments, the liquid supply module 202 and the power supply module 201 can also be detachably connected via a detachable snap-fit.

[0229] Figure 20 shows the host 200 in the twelfth embodiment of the present invention. In this embodiment, the bracket 27 and the liquid storage shell 21b are connected to each other by means of a snap fastener (including a detachable snap fastener and a non-detachable snap fastener).

[0230] Specifically, the outer surface of the tubular portion 271 of the support 27 may have a plurality of buckles 2711 protruding, which are evenly spaced around the circumference of the tubular portion 271. The wall surface of the liquid-collecting cavity 2431 of the liquid storage shell 21b is recessed to form a plurality of slots 2438 corresponding to the plurality of buckles 2711. The buckles 2711 and the slots 2438 are engaged with each other, thereby securing the support 27 in the liquid storage shell 21b.

[0231] Of course, in other embodiments, a groove may be formed on the outer surface of the support 27, and a buckle may be formed on the cavity wall of the liquid-collecting cavity 2431.

[0232] Figures 21 and 22 show the host 200 in the thirteenth embodiment of the present invention. The difference between this embodiment and the previous embodiments is that the entire cavity 215 in this embodiment is open on one side in the X direction. That is, the cavity 215 has an opening 2150 in the X direction, which extends downwards from the upper end face (the end face in the Z direction) of the power supply housing 21a to communicate with the receiving cavity 216. A portion of the atomizing device 100 is exposed outside the housing 21 through the opening 2150.

[0233] Figure 23 shows the host 200 in the fourteenth embodiment of the present invention. The difference between the host 200 and the thirteenth embodiment is that the host 200 in this embodiment also includes a cover 21c that covers the opening 2150 of the cavity 215.

[0234] The cover 21c can be detachably connected to the power supply housing 21a by magnetic attraction. Specifically, the power supply housing 21a is provided with at least one first magnetic member 205 on the side corresponding to the opening 2150, and the cover 21c is provided with at least one second magnetic member. The first magnetic member 205 and the second magnetic member attract each other magnetically, thereby fixing the cover 21c and the power supply housing 21a together.

[0235] The cover 21c cooperates with the power supply housing 21a to completely cover the atomizing device 100 inside the housing 21. Of course, a portion of the atomizing device 100 may also protrude outside the housing 21.

[0236] Figure 24 shows the host 200 in the fifteenth embodiment of the present invention, which differs from the fourteenth embodiment in that the cover 21c in this embodiment is rotatably connected to the power supply housing 21a. The rotation axis of the cover 21c can be along the Z direction. By rotating the cover 21c, the opening 2150 can be opened or closed.

[0237] Figure 25 shows the host 200 according to the sixteenth embodiment of the present invention. In this embodiment, the power supply housing 21a has an opening 2160 on one side in the Z direction, through which the liquid supply module 202 can be inserted into the receiving cavity 216 of the power supply housing 21a. Furthermore, the opening 2160 of the receiving cavity 216 and the opening 211 of the accommodating cavity 210 are arranged opposite each other in the Z direction. The power supply housing 21a and the liquid storage housing 21b together form the outer shell of the host 200.

[0238] Figure 26 illustrates the host 200 according to the seventeenth embodiment of the present invention. The difference between this embodiment and the thirteenth embodiment is that, in this embodiment, the power supply housing 21a includes a first portion 2171 and a second portion 2172. The first portion 2171 has an opening 2160 on the side in the Z direction away from the opening 211, through which the liquid supply module 202 can be inserted. The second portion 2172 covers the opening 2160; specifically, the second portion 2172 can be tightly fitted into the opening 2160 for fixation. Thus, the liquid supply module 202 is completely concealed within the power supply housing 21a, and the liquid storage housing 21b does not constitute part of the appearance of the host 200.

[0239] Figure 27 shows the host 200 in the eighteenth embodiment of the present invention. In this embodiment, the power supply housing 21a has an opening on one side in the Y direction, through which the liquid supply module 202 can be installed into the receiving cavity 216 of the power supply housing 21a.

[0240] Figures 28 and 29 show the electronic atomization system 1 in the nineteenth embodiment of the present invention. In this embodiment, the host 200 further includes a pushing mechanism 203, which is movably disposed on the housing 21. The user can push the pushing mechanism 203 to push the atomizing device 100 at least partially out of the host 200, thereby facilitating the user to remove the atomizing device 100.

[0241] The side wall of the housing 21 is provided with a slide groove 204 for sliding installation of the push mechanism 203. The push mechanism 203 is partially located outside the housing 21 for easy user operation. The push mechanism 203 is partially located in the receiving cavity 210 so as to abut against the atomizing device 100 located in the receiving cavity 210.

[0242] Understandably, the above-mentioned technical features can be used in any combination without restriction.

[0243] The above embodiments merely illustrate specific implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of the present invention, and can also make several modifications and improvements, all of which fall within the protection scope of the present invention. Therefore, all equivalent transformations and modifications made with respect to the scope of the claims of the present invention should fall within the scope of the claims of the present invention.
