[0002] Electronic atomization systems in related technologies typically include an electronic atomizing device and a main unit. The main unit supplies liquid to the electronic atomizing device for replenishment. The atomizer of the electronic atomizing device is a replaceable, standardized component; it is discarded when the liquid matrix in the atomizer is depleted, resulting in waste. Currently, there are also open-type electronic atomizing devices that can be refilled, but these are usually refilled by the user, which is inconvenient. Existing automatic refilling systems are complex in structure, difficult to manufacture and assemble, costly, and require complex electronic control schemes to achieve refilling.

[0006] In some embodiments, the reservoir includes a reservoir having multiple segments of differential capillary forces.

[0007] In some embodiments, there are at least two liquid storage devices, and the at least two liquid storage devices are coaxially arranged.

[0008] In some embodiments, at least two of the liquid reservoirs are configured with differential capillary forces.

[0011] An electronic atomization system is also constructed, including:

[0012] The host includes a housing and a liquid guiding structure. The housing has a first cavity and a second cavity formed on its inner side for storing a liquid matrix. The liquid guiding structure is at least partially disposed in the second cavity and is in fluid communication with the first cavity.

[0013] The electronic atomizing device of the present invention is installed in the second cavity when connected to the main unit. The liquid guiding structure is installed from the liquid inlet into the electronic atomizing device and contacts the liquid storage component to guide the liquid.

[0014] In some embodiments, the housing has an opening communicating with the second cavity, the housing includes a first end and a second end disposed opposite to the first end; the opening is at least partially disposed at the first end.

In some embodiments, the second partition 14b and the third partition 14c can also be omitted. In some embodiments, the housing 10 may include only one large cavity, which can be defined by the first end wall 11, the second end wall 12, and the various side walls, in which the liquid storage device 20 can be accommodated. In some embodiments, the large cavity can also accommodate the power supply 30, the motherboard, and the electrical connection structure 40.

[0050] In this embodiment, the liquid storage device 20 can be pushed into the mounting cavity 15 from the mounting port 16 on one side, and the outer wall of the liquid storage device 20 can be flush with the outer wall of the housing 10, so that the appearance of the entire host A is flat.

[0051] In this embodiment, the liquid storage device 20 can be detachably connected to the housing 10. That is, after the liquid storage device 20 is pushed into the housing 10, it can also be pulled out from the mounting port 16 of the housing 10, which facilitates the replacement of the liquid storage device 20. The liquid storage device 20 can be fixed by its outer wall being in close contact with the inner wall of the housing 10, or it can be fixed by being mounted on the second end wall 12 and supported by the second end wall 12.

The cover portion 20b can be correspondingly disposed with the mounting port 16 and can cover the mounting port 16. The cover portion 20b can be a curved structure and can form part of the appearance of the main unit A. When the cover portion 20b covers the mounting port 16, the cover portion 20b can be flush with the fourth sidewall 13d. In some embodiments, the cover portion 20b can be omitted.

[0055] A first cavity 210 and a second cavity 211 are formed inside the housing 10. Specifically, the first cavity 210 and the second cavity 211 are formed in the liquid storage shell 21. Specifically, the first cavity 210 is formed in the first shell 21a, and the second cavity 211 is formed in the second shell 21b. The central axes of the first cavity 210 and the second cavity 211 may be arranged in parallel. In this embodiment, the first cavity 210 can be used to store a liquid matrix. The second cavity 211 can be used to accommodate at least a portion of the electronic atomizing device B. When the liquid storage device 20 is assembled with the housing 10, the second cavity 211 can communicate with the mounting channel 17 through the connecting port 2110, and then with the opening 171. The electronic atomizing device B can be inserted into the second cavity 211 from the opening 171 along the mounting channel 17. In some embodiments, the second cavity 211 may be partially formed in the housing 10 and partially formed in the liquid storage shell 21, that is, the second cavity 211 may include the mounting channel 17.

[0056] In this embodiment, the first cavity 210 and the second cavity 211 are connected. A liquid guiding channel 212 is provided between the first cavity 210 and the second cavity 211, which can be used to output the liquid matrix in the first cavity 210. The liquid guiding channel 212 can be at least partially formed on the side wall of the second housing 21b facing the first housing 21a.

[0057] The main unit A also includes a bracket 22 and a liquid guiding structure 23, which can be disposed in the second cavity 211. The bracket 22 can be used for the installation of the liquid guiding structure 23 and for supporting the electronic atomizing device B. In some embodiments, the bracket 22 facilitates the replacement of the liquid guiding structure 23. The liquid guiding structure 23 is mounted on the bracket 22 and can communicate with the first cavity 210. Specifically, in this embodiment, the liquid guiding structure 23 can communicate with the first cavity 210 through the liquid guiding channel 212. The liquid guiding structure 23 can extend axially along the second cavity 211. In this embodiment, the liquid guiding structure 23 can be inserted into the electronic atomizing device B to introduce the liquid matrix in the second cavity 211 into the electronic atomizing device B. In some embodiments, the end face and / or side face (which can be the inner or outer side face) of the liquid guiding structure 23 can be in contact fluid communication with the liquid storage component 531 in the electronic atomizing device B.

[0058] In this embodiment, the bracket 22 may include a first seat 221, a second seat 222, and a connecting arm 223. The first seat 221 is disposed in the second cavity 211 and is located near the end of the second cavity 211 away from the communication opening 2110. The second seat 222 is disposed at the opening 2210. The first seat 221 and the second seat 222 are connected by the connecting arm 223, and there may be two connecting arms 223, which are arranged opposite to each other and spaced apart. In this embodiment, the first seat 221, the second seat 222, and the connecting arm 223 may be an integrally formed structure.

[0059] In this embodiment, the cross-sectional shape and size of the first seat 221 can be adapted to the cross-sectional shape and size of the second cavity 211. In the second cavity 211, the area between the first seat 221 and the communication port 2110 can form a receiving area 2111, which can be used to receive at least a portion of the electronic atomizing device B. A through hole 2211 can be provided on the first seat 221, located at the central axis of the first seat 221, which can be used for the passage of the liquid guiding structure 23. In this embodiment, the second seat 222 is generally annular and has a central through hole 2221, which can be coaxially arranged with the second cavity 211 for the electronic atomizing device B to pass through.

[0060] In some embodiments, the support 22 may not be limited to the structure described above. In some embodiments, the second seat 222 and the connecting arm 223 may be omitted.

[0061] In this embodiment, the liquid guiding structure 23 is detachably disposed in the second cavity 211. By inserting the liquid guiding structure 23 into the second cavity 211, it is easy to replace the liquid guiding structure 23. Of course, it is understood that in some other embodiments, the liquid guiding structure 23 can form a non-detachable structure with the second cavity 211 after being installed in the second cavity 211.

[0062] In this embodiment, the liquid guiding structure 23 is an automatic liquid guiding structure, which can automatically guide liquid to the electronic atomizing device B. Furthermore, the liquid guiding structure 23 can be a capillary liquid guiding structure, which can transport the liquid matrix through capillary force. When the electronic atomizing device B is assembled with the main unit A, the liquid matrix in the first cavity 210 can be transferred to the electronic atomizing device B through the capillary force of the liquid guiding structure 23, thereby achieving an automatic liquid injection effect. This liquid injection operation is convenient, provides a high level of user experience, and requires no other liquid injection structures or additional operations.

[0063] In some other embodiments, the liquid guiding structure 23 may not be limited to guiding the liquid through capillary action. In some embodiments, the liquid guiding structure 23 may also guide the liquid through gravity or through a combination of gravity and capillary action.

[0064] like Figures 10 to 11 As shown, in this embodiment, the liquid guiding structure 23 may include a liquid guiding element 231. The liquid guiding element 231 can pass through the through hole 2211 of the first base 221 and can extend axially along the second cavity 211. In this embodiment, the liquid guiding element 231 can be coaxially arranged with the second cavity 211. When the electronic atomizing device B is assembled with the main unit A, the liquid guiding element 231 can be installed in the electronic atomizing device B to transport the liquid matrix in the liquid storage device 20 to the electronic atomizing device B.

[0065] In this embodiment, the liquid guiding component 231 is a hollow cylindrical structure that can be sleeved on the plug-in structure 213 to prevent the liquid guiding component 231 from being pulled out along with the electronic atomizing device B. Its cross-section can be any suitable shape, such as circular, annular, or square. Specifically, in this embodiment, the liquid guiding component 231 is preferably cylindrical, and its cross-section can be approximately annular.

[0066] In this embodiment, the liquid guiding element 231 comprises any suitable material and combination of materials capable of transporting the liquid aerosol forming matrix toward the atomizing device. It can be a capillary material, which may include sponge or foam materials, ceramic-based or graphite-based materials in the form of fibers or sintered powders, 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)) or ceramics. The capillary can have any suitable capillary action to be used with different liquid physical properties.

[0067] Capillary materials can include materials that are porous themselves, such as ceramic materials like alumina (corundum). Alternatively, porous materials can include materials having multiple fabricated micropores to allow the liquid flotation matrix to migrate into the atomizing device. Porous materials can include hydrophilic materials to improve the distribution and diffusion of the liquid flotation matrix. A particularly preferred one or more materials will depend on the physical properties of the liquid flotation matrix. Examples of suitable materials are capillary materials, such as sponge or foam materials, ceramic-based or graphite-based materials in the form of fibers or sintered powders, 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)), or ceramics. Porous materials can have any suitable porosity to be used with different liquid physical properties.

[0068] The liquid guiding component 231 can also be made of other materials with capillary channels, such as silicone, plastic, stainless steel, glass, etc.

[0069] In this embodiment, the liquid guiding structure 23 further includes a support and fixing member 232. This support and fixing member 232 can be used to connect and fix the liquid guiding member 231 to the liquid storage shell 21, and provides the liquid guiding member 231 with a certain supporting strength to prevent the liquid guiding structure 23 from bending when the liquid guiding member 231 is assembled with the electronic atomizing device B. In this embodiment, the support and fixing member 232 can be inserted into the second cavity 211, and the liquid guiding member 231 can be sleeved on a portion of the periphery of the support and fixing member 232.

[0070] In this embodiment, the liquid storage device 20 may include a first sealing structure 24, which may be sleeved on a portion of the outer periphery of the bracket 22. Specifically, the first sealing structure 24 may be sleeved on the outer periphery of the first seat 221 and may be interference-fitted with the first seat 221. In this embodiment, the first sealing structure 24 may be, but is not limited to, a silicone sleeve. In some embodiments, the first sealing structure 24 may be omitted.

[0071] In this embodiment, the liquid storage device 20 may further include a second sealing structure 25, which may be sleeved on the bracket 22, specifically on the outer periphery of the first seat 221. The second sealing structure 25 may be a sealing ring, which can seal the gap between the first seat 221 and the second housing 21b. In some embodiments, the second sealing structure 25 may be, but is not limited to, a silicone sealing ring. In some embodiments, the second sealing structure 25 may be omitted.

[0072] In this embodiment, the liquid storage device 20 further includes a liquid storage structure 26, which is sleeved on a portion of the outer periphery of the liquid guiding structure 23 and is in fluid communication with the first cavity 210. The liquid storage structure 26 is disposed in the bracket 22, sleeved on the outer periphery of the portion of the liquid guiding structure 23 outside the accommodating area 2111, and communicates with the first cavity 210 through the liquid guiding channel 212. Specifically, it can be installed in the first seat 221 and can be interference-fitted with the bracket 22 and the liquid guiding structure 23, thereby preventing the liquid matrix from leaking out of the bracket 22. In this embodiment, the liquid storage structure 26 can be a porous structure. Specifically, in this embodiment, the liquid storage structure 26 includes any suitable material and combination of multiple materials capable of transporting the liquid aerosol forming matrix toward the atomizing device.

The capillary can have any suitable capillary action to be used with different liquid physical properties.

[0073] Capillary materials can include materials that are porous themselves, such as ceramic materials like alumina (corundum). Alternatively, porous materials can include materials having multiple fabricated micropores to allow the liquid flotation matrix to migrate into the atomizing device. Porous materials can include hydrophilic materials to improve the distribution and diffusion of the liquid flotation matrix. A particularly preferred one or more materials will depend on the physical properties of the liquid flotation matrix. Examples of suitable materials are capillary materials, such as sponge or foam materials, ceramic-based or graphite-based materials in the form of fibers or sintered powders, 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)), or ceramics. Porous materials can have any suitable porosity to be used with different liquid physical properties.

[0074] The liquid storage structure 26 can also be made of other materials with capillary channels, such as silicone, plastic, stainless steel, glass, etc.

[0075] In this embodiment, the liquid storage device 20 may further include a liquid absorption structure 27, which may be disposed in the liquid guiding channel 212. One end of the liquid absorption structure 27 may communicate with the first cavity 210, and the other end may communicate with the liquid guiding structure 23. The liquid absorption structure 27 may adsorb the liquid matrix in the first cavity 210 and transport it to the liquid guiding structure 23. Specifically, the liquid absorption structure 27 may be in close contact with the outer wall of the liquid storage structure 26, through which the liquid matrix is ​​guided to the liquid guiding structure 23. In this embodiment, the liquid absorption structure 27 may further prevent leakage. In some embodiments, the liquid absorption structure 27 may be omitted. In this embodiment, the liquid absorption structure 27 can be a porous structure. Specifically, in this embodiment, the liquid storage structure 26 includes any suitable material and combination of multiple materials capable of transporting liquid aerosol to the atomizing device to form a matrix. This material can be a capillary material, which may include sponge or foam material, ceramic-based or graphite-based material in the form of fibers or sintered powder, foamed metal or plastic material, fibrous material (e.g., made from virgin or pressed fibers (e.g., cellulose acetate fiber, polyester fiber, bonded polyolefin fiber, polyethylene fiber, polyester fiber, or polypropylene fiber, nylon fiber)) or ceramic. The capillary can have any suitable capillary action to be used with different liquid physical properties.

[0076] Capillary materials can include materials that are porous themselves, such as ceramic materials like alumina (corundum). Alternatively, porous materials can include materials having multiple fabricated micropores to allow the liquid flotation matrix to migrate into the atomizing device. Porous materials can include hydrophilic materials to improve the distribution and diffusion of the liquid flotation matrix. A particularly preferred one or more materials will depend on the physical properties of the liquid flotation matrix. Examples of suitable materials are capillary materials, such as sponge or foam materials, ceramic-based or graphite-based materials in the form of fibers or sintered powders, 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)), or ceramics. Porous materials can have any suitable porosity to be used with different liquid physical properties.

[0077] The liquid absorption structure 27 can also be made of other materials with capillary channels, such as silicone, plastic, stainless steel, glass, etc.

[0078] like Figure 6and Figure 7 As shown, in this embodiment, the electronic atomizing device B may include an atomizing unit 50 and a power supply unit 60; the power supply unit 60 may be electrically connected to the atomizing unit 50 to supply power to the atomizing unit 50. In this embodiment, the power supply unit 60 is coaxially arranged with the atomizing unit 50, and the power supply unit 60 may be located at one end of the atomizing unit 50.

[0079] The atomizing unit 50 may include a housing 51, a heating element 52, and a liquid storage component 53. The housing 51 can house the heating element 52 and the liquid storage component 53. The heating element 52 can be fitted around a portion of the outer periphery of the liquid storage component 53 and can be connected to the power supply unit 60, which can be used to heat the liquid matrix stored in the liquid storage component 53. The liquid storage component 53, disposed within the housing 51, can be used to store the liquid matrix. In some other embodiments, the heating element 52 may also be embedded in the liquid storage component 52 to contact it.

[0080] In this embodiment, the outer shell 51 can be a generally hollow columnar structure. A liquid inlet 511 can be provided on the outer shell 51, located at the central axis of the outer shell 51 and at the end of the outer shell 51 furthest from the power supply unit 60. When the electronic atomizing device B is assembled into the second cavity 211, the liquid guiding structure 23 can be installed into the electronic atomizing device B through the liquid inlet 511, contacting the liquid storage component 53 to guide the liquid. In some other embodiments, the liquid inlet 511 can also be offset from the central axis of the outer shell 51. In this embodiment, the electronic atomizing device B also includes a suction port, which can be the liquid inlet 511. That is, the suction port and the liquid inlet 511 can be the same. By sharing the suction port and the liquid inlet 511, the number of openings in the housing 10 can be reduced, thereby simplifying the structure of the electronic atomizing device B and the forming process of the housing 10.

[0081] In this embodiment, the heating element 52 may be columnar and hollow. The heating element 52 may be coaxially arranged with the outer shell 51 and the liquid storage component 53, meaning it may communicate with the suction port (i.e., the liquid inlet 511). When energized, it can heat the liquid matrix on the liquid storage component 53, generating an aerosol for the user to inhale. In this embodiment, the heating element 52 may include a tubular substrate and a heating element disposed on the substrate. The substrate may be, but is not limited to, a ceramic substrate. In some embodiments, the substrate may also be a quartz tube or a material with capillary channels, such as cotton, foam material, silicone tubes with microgrooves or micropores exhibiting capillary action, stainless steel tubes, etc. The heating element is disposed on the inner or outer surface of the substrate.

[0082] In this embodiment, the liquid storage assembly 53 may include at least one liquid storage element 531, which is disposed between the liquid inlet 511 and the heating element 52. When the electronic atomizing device B is assembled into the second cavity 211, the liquid guiding structure 23 can be installed into the electronic atomizing device B from the liquid inlet 511, contacting the liquid storage element 531, thereby guiding the liquid matrix in the first cavity 210 onto the liquid storage element 531. The liquid storage element 531 can be liquid-guidedly connected to the heating element 52, and the liquid matrix on the liquid storage element 531 can be heated by the heating element 52 and then output from the suction port (i.e., the liquid inlet 511). In some embodiments, the liquid guiding structure 23 can contact the end face and / or side face (including the inner or outer side face) of the liquid storage element 531 to form fluid communication. The side liquid guiding communication method can make the liquid guiding area larger and the liquid injection faster.

[0083] In this embodiment, the liquid reservoir 531 can be any suitable material or combination of materials capable of transporting the liquid aerosol-forming matrix toward the atomizing device. It can be a capillary material, which may include sponge or foam materials, ceramic-based or graphite-based materials in the form of fibers or sintered powders, 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)) or ceramics. The capillary can have any suitable capillary action to be used with different liquid physical properties.

[0084] Capillary materials can include materials that are porous themselves, such as ceramic materials like alumina (corundum). Alternatively, porous materials can include materials having multiple fabricated micropores to allow the liquid flotation matrix to migrate into the atomizing device. Porous materials can include hydrophilic materials to improve the distribution and diffusion of the liquid flotation matrix. A particularly preferred one or more materials will depend on the physical properties of the liquid flotation matrix. Examples of suitable materials are capillary materials, such as sponge or foam materials, ceramic-based or graphite-based materials in the form of fibers or sintered powders, 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)), or ceramics. Porous materials can have any suitable porosity to be used with different liquid physical properties.

[0085] The liquid reservoir 531 can also be made of other materials with capillary channels, such as silicone, plastic, stainless steel, glass, etc.

[0086] In this embodiment, the liquid storage component 531 can be cylindrical and hollow with both ends open. An airflow channel 5310 can be formed on the inner side of the liquid storage component 531. This airflow channel 5310 can communicate with the heating element 52 and with the suction port (i.e., the liquid inlet 511). That is, the liquid guiding structure 23 can be inserted from the suction port (i.e., the liquid inlet 511) into the airflow channel 5310. The outer wall of the liquid guiding structure 23 can contact the inner wall of the liquid storage component 531, thereby enabling fluid communication between them. The liquid matrix transmitted by the liquid guiding structure 23 can be drawn by the capillary action of the liquid storage component 531. In this embodiment, the liquid guiding structure 23 and the liquid storage component 531 can achieve close contact through an interference fit.

[0087] In this embodiment, the capillary force of the liquid guiding structure 23 and each liquid storage element 531 can be basically the same. In other embodiments, the liquid guiding structure 23 can also form multiple segments of capillary force with the liquid storage element 531 in the liquid storage assembly 53, including the following cases:

[0088] This includes the following situations:

[0089] (1) The capillary forces of the liquid guiding structure 23 are basically the same, and the capillary forces of the liquid storage component 53 are basically the same, but the capillary force of the liquid guiding structure 23 is greater than or less than the capillary force of the liquid storage component 53.

[0090] (2) The capillary force of the liquid guiding structure 23 is basically the same, and the liquid storage component 53 forms multiple segments with different capillary forces.

[0091] (3) The liquid guiding structure 23 forms multiple segments with different capillary forces, while the capillary forces of the liquid storage component 53 are basically the same.

[0092] (4) The liquid guiding structure 23 forms multiple segments of different capillary forces, and the liquid storage component 53 forms multiple segments of different capillary forces.

[0093] The liquid guiding structure 23 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 liquid guiding structure 23 is larger or smaller. For example, the capillary force of the liquid guiding structure 23 first increases and then decreases or first decreases and then increases; (2) the capillary force of the multiple segments of the liquid guiding structure 23 gradually increases along the transport direction of the liquid matrix, that is, the closer to the liquid storage component 53, the greater the capillary force.

[0094] The liquid storage component 53 has 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 liquid storage component 53 is larger or smaller. For example, the capillary force of the liquid storage component 53 first increases and then decreases or first decreases and then increases; (2) the capillary force of the multiple segments of the liquid storage component 53 gradually increases along the transport direction of the liquid matrix, that is, the capillary force is greater the further away from the liquid guiding structure 23.

[0095] 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.

[0096] The formation of the multi-segment capillary force is unrestricted. Specifically, the liquid guiding structure 23 includes multiple liquid guiding elements 231, the capillary force of which gradually increases along the transport direction of the liquid matrix; and / or, the liquid storage assembly 53 includes multiple liquid storage elements, the capillary force of which gradually increases along the transport direction of the liquid matrix. Generally, the multiple liquid guiding elements 231 can achieve different capillary forces by using different materials and / or having different densities.

[0097] The capillary forces on the same liquid guiding component 231 and / or liquid storage component 531 can be substantially consistent. Alternatively, multiple segments with varying capillary forces can be formed on the same liquid guiding component 231 and / or liquid storage component 531. For example, if the liquid guiding component 231 and / or liquid storage component 531 are made of cotton-like material, different densities can be formed on the liquid guiding component 231 and / or liquid storage component 531 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 231 and / or liquid storage component 531 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.

[0098] In this embodiment, there can be at least two liquid storage elements 531, and the capillary forces of these at least two liquid storage elements 531 are set differently. Specifically, the capillary forces of these at least two liquid storage elements 531 can gradually decrease along the direction of liquid matrix transport. Specifically, the at least two liquid storage elements 531 can be coaxially arranged, that is, two adjacent liquid storage elements 531 can be interconnected. Generally, multiple liquid storage elements 531 can obtain different capillary forces by using different materials and / or having different densities.

[0099] Furthermore, in this embodiment, there can be three liquid storage components 531, namely, the liquid storage components 531 may include a first liquid storage component 5311, a second liquid storage component 5312, and a third liquid storage component 5313. The first liquid storage component 5311, the second liquid storage component 5312, and the third liquid storage component 5313 are arranged sequentially from the liquid inlet 511 to the heating component 52. The first liquid storage component 5311 is located at the suction port (i.e., the liquid inlet 511). The liquid guiding structure 23 can be inserted into the first liquid storage component 5311 from the liquid inlet 511. The liquid guiding structure 23 can contact the inner wall of the first liquid storage component 5311. The liquid matrix can be transferred to the first liquid storage component 5311 through the liquid guiding structure 23, and transported from the first liquid storage component 5311, the second liquid storage component 5312 to the third liquid storage component 5313.

[0100] In some embodiments, the liquid reservoir 531 can be a single unit, and the liquid reservoir 531 has multiple segments with different capillary forces, that is, the capillary forces in its axial direction can also be set differently, and the capillary forces can gradually decrease along the liquid matrix transport direction. Generally, the capillary forces at different positions of the liquid reservoir 531 can be made different by changing the orifice diameter at different positions of the liquid reservoir 531. In other embodiments, the liquid reservoir 531 can be a single unit, and the capillary forces in its axial direction can also be set uniformly.

[0101] In this embodiment, the electronic atomizing device B further includes a mounting bracket 54, which can be inserted into the housing 51 from the end of the housing 51 away from the liquid inlet 511, for supporting and fixing the heating element 52 and the liquid storage component 531. In this embodiment, the mounting bracket 54 can also be connected to the power supply unit A.

[0102] In this embodiment, when liquid injection is required, the entire electronic atomizing device B can be installed into the second cavity 211 through the opening 171 along the installation channel 171. Simultaneously, the liquid guiding structure 23 can be inserted into the liquid storage component 531 through the liquid inlet 511. The outer wall of the liquid guiding structure 23 can contact the end face and / or side face (including the inner or outer side face) of the liquid storage component 531, thereby achieving liquid guidance. Meanwhile, the main unit A can charge the electronic atomizing device B through the electrical connection structure 40.

[0103] After liquid filling or charging, the electronic atomizing device B can be pushed out from one side of the opening 171, and the liquid guiding structure 23 can then be removed from the electronic atomizing device B.

[0104] Figure 8 A second embodiment of the electronic atomization system of the present invention is shown, which differs from the first embodiment in that the opening 171 can extend from the first end wall 11 to the second end wall 12, and the mounting port 16 can be shared with the opening 171. The outer wall of the liquid storage device 20 and the outer wall of the first cavity 210 can be provided with U-shaped openings that mate with the opening 171, thereby allowing the electronic atomization device B to have a semi-enclosed structure.

[0105] Figure 9 The third embodiment of the electronic atomization system of the present invention is shown. The difference between the third and fourth embodiments is that the opening 171 is integrally disposed on the first end wall 11 and can be a circular opening. In some embodiments, the opening 171 is not limited to being circular.

[0106] In this embodiment, a guide groove 131 may be provided on the housing 10. Specifically, the guide groove 131 may be provided on the fourth side wall 13d and may extend between the first end 10a and the second end 10b. The guide groove 131 may be a strip-shaped groove, which can be used to guide the electronic atomizing device B to be inserted into the second cavity 211 or to be pushed out of the second cavity 211.

[0107] In this embodiment, the electronic atomization system further includes a pushing mechanism 70, which is movably disposed in the guide groove 131 and can contact the electronic atomization device B, thereby pushing the electronic atomization device B into or out of the opening 171. In this embodiment, the electronic atomization device B can be detachably connected to the pushing mechanism 70.

[0108] For example, the electronic atomizing device B and the pushing mechanism 70 can be magnetically secured. That is, a first magnetic element can be provided in the electronic atomizing device B, and a second magnetic element can be provided on the side of the pushing mechanism 70 facing the electronic atomizing device B. The pushing mechanism 70 can move along the guide groove 131 by engaging with the first magnetic element of the electronic atomizing device B through the second magnetic attraction. When it is necessary to separate the electronic atomizing device B from the main unit A, the pushing mechanism 70 can be pushed so that part of the electronic atomizing device B is exposed through the opening 171. By rotating the first magnetic element of the electronic atomizing device B to separate from the second magnetic element of the pushing mechanism 70, and continuing to pull the electronic atomizing device B, the electronic atomizing device B can be separated from the main unit A. In some embodiments, the power supply unit A of the electronic atomizing device B can be made of a magnetically conductive material, or the pushing mechanism 70 can be magnetically engaged and secured with the power supply unit A through the second magnetic attraction. When the electronic atomizing device B is withdrawn from the main unit A, the pushing mechanism 70 can be separated from the electronic atomizing device B by continuing to pull the stator atomizing device B.

[0109] In some embodiments, the electronic atomizing device B and the pushing mechanism 70 can also be engaged via a snap-fit ​​mechanism. The electronic atomizing device B may be provided with a sliding groove that extends axially along the power housing of the electronic atomizing device B. A slot is provided at the end of the sliding groove facing the liquid inlet 511. The pushing mechanism 70 may be provided with a snap-fit ​​protrusion. When the electronic atomizing device B is inserted into the opening 171, the snap-fit ​​protrusion of the pushing mechanism 70 can slide along the sliding groove and fall into the slot for fixation as the electronic atomizing device B is advanced, thus connecting with the electronic atomizing device B. When the electronic atomizing device B needs to be withdrawn from the opening 171, it can be pushed towards the opening 171 by the pushing mechanism 70. When the pushing mechanism 70 reaches the guide groove 131 near the end of the opening 171, by continuing to pull out the electronic atomizing device B, the pushing mechanism 70 can slide out from the slot into the sliding groove, thereby separating the pushing mechanism 70 from the electronic atomizing device B. Finally, by twisting or continuing to pull out the electronic atomizing device B, the electronic atomizing device B can be separated from the main unit.

[0110] In some embodiments, the connection between the actuating mechanism 70 and the electronic atomizing device B may not be limited to the two methods described above.

[0111] Figure 11 and Figure 12A second embodiment of the electronic atomization system of the present invention is shown, which differs from the first embodiment in that the opening 171 can be formed on the side wall of the housing 10, specifically, it can be formed on the fourth side wall 13d, and it can extend from the first end wall 11 to the second end wall 12, that is, it can be shared with the mounting port 16. The main unit A may also include a cover 80, which can cover at least part of the opening 171, thereby accommodating the entire electronic atomization device B in the main unit A.

[0112] In this embodiment, the electronic atomizing device B and the liquid storage device 20 can be assembled first. Specifically, the electronic atomizing device B can be partially inserted into the second cavity 211 of the liquid storage device 20, while the liquid guiding structure 23 can be inserted into the electronic atomizing device B. Then, the electronic atomizing device B and the liquid storage device 20 are inserted into the housing 10 through the opening 171, and the cover 80 is then closed over the opening 171. When the electronic atomizing device B needs to be removed, the cover 80 can be removed, the opening 171 can be opened, and then the electronic atomizing device B and the liquid storage device 20 can be pulled out of the housing 10 together.

[0113] In this embodiment, the cover 80 may be semi-cylindrical and may include a cover body 81, the inner side of which is provided with a groove 82 that matches the electronic atomizing device B. When the cover 80 is closed with the housing 10, the electronic atomizing device B can be partially inserted into the groove 82.

[0114] The cover 80 and the housing 10 can be detachably connected via a connecting structure. In this embodiment, the connecting structure can be, but is not limited to, a magnetic structure. Specifically, the housing 10 may have a first magnetic element 132 on the end face of the opening 171, and the cover 80 may have a second magnetic element 83 on the side facing the housing 10. When the cover 80 closes the opening 171, the first magnetic element 132 can be attracted and fixed with the second magnetic element 83. In some embodiments, the connecting structure may also be a snap-fit ​​structure or an adhesive structure, or at least two of the following: adhesive structure, snap-fit ​​structure, and magnetic structure.

[0115] Figure 13 A fifth embodiment of the electronic atomization system of the present invention is shown, which differs from the fourth embodiment in that one side of the cover 80 is rotatably connected to the housing 10. That is, the cover 80 can be a flip-top structure. The cover 80 and the side wall of the housing 10 can be rotatably connected by a hinge structure.

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.
