[0061] An embodiment of the present disclosure provides an atomization device. Referring to Figures 1 and 2, the atomization device includes a power supply mechanism M11 (including a first shell, a power supply component 300, etc.) and an atomization mechanism M12 (including a second shell, an atomization component 600, etc.). The power supply mechanism M11 and the atomization mechanism M12 are detachably connected. When the atomization mechanism M12 is connected to the power supply mechanism M11, the power supply mechanism M11 can provide electrical energy to the atomization mechanism M12, so that the atomization mechanism M12 can atomize the atomization medium.

[0062] 3, 4 and 5, the power supply mechanism M11 includes a first shell 100, and the first shell 100 is provided with a limited space 120; a portion of the atomization mechanism M12 is inserted into the limited space 120 and is detachably connected to the power supply mechanism M11; the atomization mechanism M12 includes a second shell 400, a base 500 and an atomization assembly 600, the second shell 400 is formed with a liquid storage chamber 420, the liquid storage chamber 420 is used to accommodate the atomization medium, the base 500 is connected to the opening position of the second shell 400, the base 500 is formed with an atomization chamber 410, the atomization chamber 410 is connected to the external space, and at least a portion of the atomization assembly 600 is provided with a liquid storage chamber 420. Located between the liquid storage chamber 420 and the atomizing chamber 410, the atomizing assembly 600 is used to atomize the atomizing medium; the first shell 100 includes a first end face 150, and the opening of the limiting space 120 is located at the first end face 150. Along the insertion direction Y1 of the atomizing mechanism M12 relative to the limiting space 120, the atomizing chamber 410, the liquid storage chamber 420 and the atomizing assembly 600 do not exceed the first end face 150. In other words, along the separation direction of the atomizing mechanism M12 relative to the limiting space 120 (the opposite direction of the insertion direction Y1), the first end face 150 does not reach the position of the atomizing chamber 410, the liquid storage chamber 420 and the atomizing assembly 600.

[0063] In the embodiment of the present disclosure, when the atomizing mechanism M12 is connected to the power supply mechanism M11, the atomizing chamber 410, the liquid storage chamber 420 and the atomizing assembly 600 are all located outside the confined space 120, that is, the part of the atomizing mechanism M12 inserted into the power supply mechanism M11 does not include the atomizing chamber 410, the liquid storage chamber 420 and the atomizing assembly 600, and the atomizing chamber 410, the liquid storage chamber 420 and the atomizing assembly 600 are not located within the confined space 120.

[0064] In some embodiments, the power supply mechanism M11 is placed on a supporting surface, which can be a horizontal surface, an inclined surface, a vertical surface, etc. For example, the supporting surface is a horizontal surface, and when the atomization mechanism M12 is connected to the power supply mechanism M11, the atomization mechanism M12 is located above the power supply mechanism M11, and the highest point of the first end surface 150 is no higher than the lowest point of the atomization chamber 410, the liquid storage chamber 420, and the atomization assembly 600.

[0065] 3 , in some examples, the lowest point of the liquid storage chamber 420 is not higher than the lowest point of the atomizing chamber 410 and the atomizing assembly 600, and the highest point of the first end surface 150 is not higher than the lowest point of the liquid storage chamber 420; referring to FIG4 , in other examples, the lowest point of the atomizing chamber 410 is not higher than the lowest point of the liquid storage chamber 420 and the atomizing assembly 600, and the highest point of the first end surface 150 is not higher than the lowest point of the atomizing chamber 410; referring to FIG5 , in still other examples, the lowest point of the atomizing assembly 600 is not higher than the lowest point of the liquid storage chamber 420 and the atomizing chamber 410, and the highest point of the first end surface 150 is not higher than the lowest point of the atomizing assembly 600.

[0066] Here, the lowest point refers to the point at which the vertical distance between the structure or space and the bearing surface is the smallest, and the highest point refers to the point at which the vertical distance between the structure or space and the bearing surface is the largest; for example, the lowest point of the atomization chamber 410, the liquid storage chamber 420 and the atomization assembly 600 refers to the point closest to the bearing surface in vertical distance, and the highest point of the first end face 150 refers to the point farthest from the bearing surface in vertical distance.

[0067] Not higher than includes two cases: lower than and flush. For example, the highest point of the first end surface 150 is not higher than the lowest point of the atomizing chamber 410. The highest point of the first end surface 150 may be lower than the lowest point of the atomizing chamber 410, and the vertical distance from the highest point of the first end surface 150 to the bearing surface is less than the vertical distance from the lowest point of the atomizing chamber 410 to the bearing surface; or the highest point of the first end surface 150 may be flush with the lowest point of the atomizing chamber 410, and the vertical distance from the highest point of the first end surface 150 to the bearing surface is equal to the vertical distance from the lowest point of the atomizer to the bearing surface.

[0068] In some embodiments of the present disclosure, along the insertion direction Y1, the atomization mechanism M12 has a second end face 510 at one end close to the power supply component 300, the second end face 510 is perpendicular to the insertion direction Y1, and the second end face 510 is located on the side of the liquid storage chamber 420, the atomization chamber 410 and the atomization component 600 close to the power supply component 300; that is, the second end face 510 is located on the side of the liquid storage chamber 420 close to the power supply component 300, and on the side of the atomization chamber 410 close to the power supply component 300, and also on the side of the atomization component 600 close to the power supply component 300.

[0069] It should be noted that the second end surface 510 may be a surface of the second shell 400 or a surface of the base 500, or the second end surface 510 may be formed jointly by the second shell 400 and the base 500. In addition, the second end surface 510 is a surface perpendicular to the insertion direction Y1 and satisfies a positional relationship with the liquid storage chamber 420, the atomization chamber 410, and the atomization assembly 600. The second end surface 510 may be an outer wall surface of the second shell 400 and / or the base 500, or an inner wall surface of the second shell 400 and / or the base 500.

[0070] 3, 4, and 5, in some examples, a portion of the base 500 protrudes from the second housing 400, and the outer wall surface of the base 500 forms the second end surface 510. Referring to Figures 12 and 13, in other examples, the base 500 includes a concave groove, and the second end surface 510 is the bottom wall of the groove, that is, the second end surface 510 is the inner wall surface of the base 500.

[0071] 3, 4 and 5, when the atomization mechanism M12 is connected to the power supply mechanism M11, the vertical distance between the extension surface of the second end face 510 and the first end face 150 is the first distance L1, and the minimum vertical distance between the liquid storage chamber 420, the atomization chamber 410 and the atomization assembly 600 and the second end face 510 is greater than or equal to the first distance L1.

[0072] In the embodiment of the present disclosure, the minimum vertical distance between the liquid storage chamber 420 and the second end surface 510 is the second distance L2, the minimum vertical distance between the atomization chamber 410 and the second end surface 510 is the third distance L3, and the minimum vertical distance between the atomization assembly 600 and the second end surface 510 is the fourth distance L4.

[0073] 3 , in some examples, the second distance L2 is less than or equal to the third distance L3 and less than or equal to the fourth distance L4, and the atomizing chamber 410, the liquid storage chamber 420, and the atomizing assembly 600 do not exceed the first end face 150, specifically referring to that the second distance L2 is greater than or equal to the first distance L1; referring to FIG4 , in other examples, the third distance L3 is less than or equal to the second distance L2 and less than or equal to the fourth distance L4, and the atomizing chamber 410, the liquid storage chamber 420, and the atomizing assembly 600 do not exceed the first end face 150, specifically referring to that the third distance L3 is greater than or equal to the first distance L1; referring to FIG5 , in still other examples, the fourth distance L4 is less than or equal to the second distance L2 and less than or equal to the third distance L3, and the atomizing chamber 410, the liquid storage chamber 420, and the atomizing assembly 600 do not exceed the first end face 150, specifically referring to that the fourth distance L4 is greater than or equal to the first distance L1.

[0074] According to the technical solution of the embodiment of the present disclosure, along the insertion direction Y1 of the atomizing mechanism M12 relative to the limiting space 120, the atomizing chamber 410, the liquid storage chamber 420 and the atomizing assembly 600 do not exceed the first end face 150. On the one hand, the size of the limiting space 120 in the insertion direction Y1 is small, and the stroke of the atomizing mechanism M12 when inserted into the power supply mechanism M11 is short. Moreover, the volume of the limiting space 120 is small, and the contact area between the inner wall of the limiting space 120 and the atomizing assembly 600 is small, and the friction resistance between the two is small, which facilitates the disassembly and assembly of the atomizing mechanism M12 and the power supply mechanism M11. On the second hand, the size of the limiting space 120 in the insertion direction Y1 is small, which means that the depth of the limiting space 120 is small, which is more convenient for cleaning. On the third hand, the volume of the limiting space 120 is small, and the required structural dimensions for forming the limiting space 120 are also small, which is convenient for saving materials and also contributes to the miniaturization and lightweight of the atomizing device.

[0075] In some examples, the inner wall of the liquid storage chamber 420 is formed by the second housing 400, and the second housing 400 is provided with a channel connected to the liquid storage chamber 420, and the channel is connected to the atomization chamber 410 or the atomization assembly 600. In other examples, part of the inner wall of the liquid storage chamber 420 is formed by the second housing 400, and another part of the inner wall is formed by the base 500, that is, the base 500 and the second housing 400 enclose to form the liquid storage chamber 420.

[0076] In some examples, the liquid storage chamber 420 surrounds the atomizing chamber 410 along the circumference of the atomizing chamber 410; in other examples, the liquid storage chamber 420 and the atomizing chamber 410 are arranged in sequence along the vertical direction of the insertion direction Y1; in some other examples, there are multiple liquid storage chambers 420, and the multiple liquid storage chambers 420 are symmetrically distributed about the atomizing chamber 410; in some other examples, there are multiple liquid storage chambers 420 and multiple atomizing assemblies 600, and the liquid storage chamber 420 and the atomizing assemblies 600 are arranged correspondingly.

[0091] In the embodiment of the present disclosure, there are many possible arrangements of the first air inlet channel 530 and the air outlet channel 430. In some examples, the first air inlet channel 530 and the air outlet channel 430 are located on opposite walls of the atomizing chamber 410. For example, the first air inlet channel 530 is located on the bottom wall of the atomizing chamber 410, and the air outlet channel 430 is located on the top wall of the atomizing chamber 410.

The liquid absorbing element 620 is disposed near the liquid storage chamber 420 , and the atomizing element is disposed near the atomizing chamber 410 . The liquid absorbing element 620 can temporarily store liquid atomizing medium, and the atomizing element atomizes the atomizing medium stored in the liquid absorbing element 620 and releases it into the atomizing chamber 410 .

[0097] In the embodiment of the present disclosure, the wicking member 620 refers to a structure that transmits or delivers the atomizing medium to the atomizing member, which may be through capillary force or other forces, including but not limited to ceramic, glass, quartz or fiber.

[0098] In the embodiment of the present disclosure, the atomizing assembly 600 includes an atomizing surface 611. The atomizing assembly 600 releases the atomized atomized medium into the atomizing chamber 410 through the atomizing surface 611 so that the atomized atomized medium mixes with the external airflow. There are several possible layouts of the atomizing surface 611:

[0099] In some examples, the atomizing surface 611 is disposed on the side of the atomizing assembly 600 facing the top wall of the atomizing chamber 410; in other examples, the atomizing surface 611 is disposed on the side of the atomizing assembly 600 facing the bottom wall of the atomizing chamber 410; in still other examples, the atomizing surface 611 is disposed on the side of the atomizing assembly 600 facing the side wall of the atomizing chamber 410.

[0100] In some embodiments, the atomizing surface 611 is perpendicular to or at a certain angle to the flow direction of the atomized medium in the atomizing assembly 600. In some embodiments, the atomizing surface 611 is parallel to the flow direction of the atomized medium in the atomizing assembly 600.

[0101] In some examples, the atomized surface 611 is a plane; in other examples, the atomized surface 611 is a curved surface; in still other examples, the atomized surface 611 is a combination of a plane and a curved surface.

[0102] In some examples, the atomizing surface 611 surrounds the atomizing assembly 600 entirely; in some examples, there are multiple atomizing surfaces 611, and the multiple atomizing surfaces 611 are symmetrically distributed about the axis of the atomizing assembly 600, wherein the multiple atomizing surfaces 611 can be adjacent surfaces or opposite surfaces of the atomizing assembly 600.

[0103] In some embodiments of the present disclosure, at least a portion of the second shell 400 is a light-transmitting portion, which is made of a light-transmitting material and forms at least a portion of the wall of the liquid storage cavity 420 .

[0104] In the disclosed embodiments, the light-transmitting material may be glass, plastic, or a composite material. Glass includes soda-lime glass and tempered glass, and plastic includes acrylic, polycarbonate, and polystyrene. The remaining portions of the second housing 400 may be made of one or more materials such as metal, plastic, rubber, and fiber. The light transmittance of the remaining portions of the second housing 400 is lower than that of the light-transmitting portion.

[0105] In some examples, the light-transmitting portion is made of a highly transparent material, which is a material with a transmittance greater than or equal to 80%; in some examples, the light-transmitting portion is made of a semi-transparent material, which is a material with a transmittance greater than or equal to 10% and less than 80%.

[0106] In the embodiment of the present disclosure, the shape of the light-transmitting portion can be circular, elliptical, square, rectangular, diamond, trapezoidal, etc. The light-transmitting portion has many possible forms:

[0107] In some examples, the second shell 400 is made entirely of a light-transmitting material, and the second shell 400 has an entire light-transmitting portion; in other examples, the light-transmitting portion is located between the outer wall of the second shell 400 and the inner wall of the liquid storage chamber 420; in yet other examples, the light-transmitting portion forms part of the wall surface of the liquid storage chamber 420.

[0108] In some examples, the second shell 400 includes one light-transmitting portion; in other examples, the second shell 400 includes multiple light-transmitting portions, each liquid storage cavity 420 corresponds to one light-transmitting portion, or a single liquid storage cavity 420 corresponds to multiple light-transmitting portions.

[0109] In some embodiments, along the insertion direction Y1, the light-transmitting portion does not extend beyond the first end surface 150. In other words, along the separation direction, the first end surface 150 does not reach the location of the light-transmitting portion. This means that the minimum distance between the light-transmitting portion and the second end surface 510 is less than the first distance L1. For example, the side of the light-transmitting portion closest to the power supply assembly 300 is flush with the side of the liquid storage chamber 420 closest to the power supply assembly 300.

[0110] In some embodiments, at least a portion of the base 500 is made of a light-transmitting material, and / or a portion of the first shell 100 forming the limiting space 120 is supported by a light-transmitting material.

[0111] According to the technical solution of the embodiment of the present disclosure, the light-transmitting portion forms at least a portion of the wall of the liquid storage chamber 420, so that the user can observe the state of the atomized medium in the liquid storage chamber 420 through the light-transmitting portion, such as observing the remaining amount of the atomized medium. The first end surface 150 does not reach the position of the light-transmitting portion, thereby avoiding the first shell 100 from blocking the light-transmitting portion, thereby facilitating the user to observe the state of the atomized medium in the liquid storage chamber 420.

[0112] In the disclosed embodiment, the power supply mechanism M11 includes a power supply assembly 300. When the atomizing mechanism M12 is connected to the power supply mechanism M11, the power supply assembly 300 can be electrically connected to the atomizing assembly 600. The power supply assembly 300 provides electrical energy to the atomizing assembly 600 so that the atomizing assembly 600 can atomize the atomizing medium. There are several possible ways to electrically connect the power supply assembly 300 and the atomizing assembly 600:

[0113] In some examples, the power supply mechanism M11 and the atomization mechanism M12 both include wireless charging modules. The wireless charging module of the power supply mechanism M11 sends electrical energy to the wireless charging module of the atomization mechanism M12 in the form of electromagnetic waves, etc. The electrical connection between the two is wireless, which reduces the corresponding conductive structure settings and sealing structures of the power supply mechanism M11 and the atomization mechanism M12, and also helps to isolate the atomization chamber 410 from the outside world.

[0114] The wireless charging module may be in the form of electromagnetic induction, magnetic resonance, radio frequency, or a combination of one or more of a photoelectric conversion type. For example, the wireless charging module is in the form of electromagnetic induction.

When the atomization mechanism M12 is connected to the power supply mechanism M11, the external end of the first conductive component 810 contacts the external end of the second conductive component 820 and is electrically conductive. By utilizing the contact power supply of the first conductive component 810 and the second conductive component 820, the electrical connection is more stable, which helps to provide stable and reliable electrical energy to the atomization component 600.

[0116] In the disclosed embodiment, the first conductive member 810 and the second conductive member 820 can each be a combination of one or more of a conductive column, a conductive wire, a conductive sheet, a conductive sleeve, a conductive ring, a conductive spring, and an elastic electric needle. For example, the first conductive member 810 and the second conductive member 820 can both be elastic electric needles, and the elasticity can effectively maintain contact between the first conductive member 810 and the second conductive member 820. There are various possible implementations of the first conductive member 810 and the second conductive member 820:

[0117] In some examples, the built-in end of the first conductive member 810 is connected to the bottom wall of the atomizer assembly 600, and the bottom wall of the atomizer assembly 600 is the wall surface close to the second end face 510; in other examples, the built-in end of the first conductive member 810 is connected to the top wall of the atomizer assembly 600, and the top wall of the atomizer assembly 600 is the wall surface away from the second end face 510; in still other examples, the built-in end of the first conductive member 810 is connected to the side wall of the atomizer assembly 600, and the side wall of the atomizer assembly 600 is the wall surface between the top wall and the bottom wall, and the side wall of the atomizer assembly 600 is arranged opposite to the side wall of the atomizer chamber 410.

[0118] In some examples, the contact position of the first conductive member 810 and the second conductive member 820 is located on the end face of the atomizer assembly 600, such as the second end face 510; in other examples, the contact position of the first conductive member 810 and the second conductive member 820 is located on the peripheral side of the atomizer assembly 600, such as the inner wall of the limiting space 120.

[0119] In some examples, there may be one or more (including two) first conductive members 810, and one or more (including two) second conductive members 820, with the plurality of first conductive members 810 and the plurality of second conductive members 820 being arranged in a one-to-one correspondence. For example, there may be two first conductive members 810 and two second conductive members 820, and the central axes of the two first conductive members 810 may be arranged in parallel.

[0120] In the embodiments of the present disclosure, the power supply component 300 has multiple possible forms. In some examples, the power supply component 300 includes a battery, which may be a lithium-ion battery, a lithium polymer battery, a nickel-metal hydride battery, etc. The battery may be a primary battery or a secondary battery; in other examples, the power supply component 300 includes a plug interface, which is used to connect to an external power source; in still other examples, the power supply component 300 includes a battery and a plug interface, which can be used to directly power the atomization component 600 and to charge the battery.

[0121] In the embodiment of the present disclosure, the second housing 400 includes a limiting structure 110, which encloses a limiting space 120. The surface of the limiting structure 110 facing the atomizer assembly 600 and adjacent to the inner wall of the limiting space 120 is a first end surface 150. There are multiple possible implementations of the limiting structure 110 and the limiting space 120:

[0122] In some examples, the limiting structure 110 is an annular structure, the inner side of the limiting structure 110 forms a limiting space 120, and the first end face 150 is a continuous annular surface; in other examples, the limiting structure 110 is an annular structure, and along the circumferential direction of the limiting structure 110, the limiting structure 110 includes alternating notches and protrusions, and the surface of the protrusion facing the atomization assembly 600 and adjacent to the inner wall of the limiting space 120 forms a sub-end face, and the sub-end faces of multiple protrusions together form the first end face 150.

[0123] In some examples, the first end surface 150 is disposed perpendicular to the insertion direction Y1 ; in other examples, the first end surface 150 is disposed at an acute angle or an obtuse angle to the insertion direction Y1 .

[0124] In the embodiment of the present disclosure, the shape of the annular structure can be a circular ring, a square ring, an elliptical ring, a triangular ring, a racetrack ring, a waist-shaped ring, a diamond ring, a hexagonal ring, etc. The shape of the annular structure can be regular or irregular. For example, the annular structure of the first end surface 150 is an elliptical ring.

[0125] In some examples, the second shell 400 of the atomization mechanism M12 is connected to the limiting structure 110; in other examples, the base 500 of the atomization mechanism M12 is connected to the limiting structure 110; in still other examples, the second shell 400 and the base 500 are respectively connected to the limiting structure 110.

[0126] In the disclosed embodiment, there are multiple possible connection modes between the atomizing mechanism M12 and the limiting mechanism:

[0127] In some examples, the inner wall of the limiting space 120 corresponding to the limiting structure 110 at least partially abuts against the outer wall of the atomization mechanism M12, and the limiting structure 110 and the atomization mechanism M12 are fixed by friction, and the user overcomes the friction to achieve disassembly and assembly of the atomization mechanism M12.

[0128] In other examples, the inner wall of the limiting structure 110 and the outer wall of the atomization mechanism M12 are respectively provided with limiting holes and limiting protrusions, at least the limiting protrusions can be elastically deformed, and the atomization mechanism M12 and the limiting structure 110 are fixed by the clamping connection between the limiting holes and the limiting protrusions. The user overcomes the elastic force of the elastic deformation to realize the disassembly and assembly of the atomization mechanism M12.

[0129] In some other examples, the inner wall of the limiting structure 110 is provided with an internal thread, and the outer wall of the atomization mechanism M12 is provided with an external thread, and the internal thread and the external thread are adapted to each other, thereby fixing the atomization mechanism M12 and the limiting structure 110. In addition, the atomization mechanism M12 and the limiting structure 110 can also be fixed by fasteners such as screws, bolts, and studs.

[0130] Here, the outer wall of the atomizing mechanism M12 includes the outer wall of the second housing 400 and the outer wall of the base 500 .

The magnetic bodies of the atomizing mechanism M12 and the power supply mechanism M11 can interact with each other, and the user overcomes the magnetic force of the magnetic bodies to achieve disassembly and assembly of the atomizing mechanism M12.

[0132] In the embodiments of the present disclosure, there are multiple possible implementations of the magnetic body:

[0133] In some examples, the magnetic properties of the atomizer mechanism M12 and the magnetic properties of the power supply mechanism M11 on the side where they are close to each other are opposite, and the two magnetic properties attract each other, thereby fixing the atomizer mechanism M12 and the power supply mechanism M11. Of course, the magnetic property can also be changed to a negative pressure adsorption component. In other examples, the magnetic properties of the atomizer mechanism M12 and the magnetic properties of the power supply mechanism M11 on the side where they are close to each other are the same, and the two magnetic properties repel each other, which can serve as an auxiliary power when the atomizer mechanism M12 and the power supply mechanism M11 are separated.

[0134] In some examples, the magnetic body is arranged on the peripheral side of the limiting structure 110 and the atomization mechanism M12, and the direction of the magnetic force is at an angle to the insertion direction Y1; in other examples, the magnetic body is arranged at the end of the limiting space 120 and the atomization mechanism M12, and the direction of the magnetic force is parallel to the insertion direction Y1.

[0135] In some examples, the limiting space 120 and the power supply component 300 are arranged in sequence along the insertion direction Y1, and the size of the first shell 100 perpendicular to the insertion direction Y1 is smaller, which is convenient for holding; in other examples, the arrangement direction of the limiting space 120 and the power supply component 300 is perpendicular to the insertion direction Y1, and the size of the first shell 100 along the insertion direction Y1 is smaller, and the center of gravity is more stable. Here, the limiting structure 110 can separate the limiting space 120 and the space where the power supply component 300 is located.

[0136] In some embodiments of the present disclosure, the volume of the limiting space 120 can be adjusted so as to be suitable for atomization mechanisms M12 of different sizes, thereby improving the universality of the power supply mechanism M11.

The first channel opening 561 of the balancing channel 560 is in communication with the liquid storage chamber 420, and the second channel opening 562 of the balancing channel 560 is in communication with the atomization chamber 410. The base 500 is further provided with a liquid storage structure 900, and the second channel opening 562 of the balancing channel 560 is in communication with the liquid storage structure 900. The liquid storage structure 900 can be used to store liquid flowing into the liquid storage structure 900.

[0146] The liquid storage cavity 420 is provided inside the second shell 400 , and the second shell 400 defines the liquid storage 302 , or the second shell 400 and the base 500 jointly define the liquid storage cavity 420 .

[0147] The second housing 400 is the outer housing of the atomizing mechanism M12 and has an air outlet passage 430 formed therein. At least a portion of the base 500 is disposed within the second housing 400 .

[0148] The air outlet channel 430 may be located in the middle area of ​​the second shell 400 , or may be located on the side of the middle area of ​​the second shell 400 .

[0149] In some examples, the top of the base 500 and the inner sidewall of the second housing 400 define a liquid storage chamber 420 for storing the aerosol-generating substrate, and the liquid storage chamber 420 is arranged around the air outlet channel 430. In other examples, the liquid storage chamber 420 may also be formed inside the second housing 400.

[0150] The atomizing mechanism M12 refers to a structure having an atomizing function in the atomizing device M10 , and the aerosol generating substrate generates an aerosol in the atomizing mechanism M12 .

[0151] Exemplarily, at least a portion of the base 500 is disposed in the second shell 400 , which may mean that part of the structure of the base 500 is disposed in the second shell 400 , or the entire structure of the base 500 is disposed in the second shell 400 .

[0152] Illustratively, the base 500 is formed with an air inlet channel, which connects the outside and the atomization chamber 410 .

[0153] Illustratively, the base 500 is formed with an atomizing chamber 410 and a liquid inlet channel 520. The liquid inlet channel 520 connects the liquid storage chamber 420 and the atomizing assembly 600. The atomizing chamber 410 is in gaseous communication with the air outlet channel 430. The aerosol-generating substrate in the liquid storage chamber 420 enters the atomizing assembly 600 through the liquid inlet channel 520 for atomization. The aerosol formed after atomization flows through the air outlet channel 430 along with the air flowing into the air inlet channel and is discharged to the outside through the first channel opening 561 for use by the user.

[0154] The atomizing assembly 600 is used to absorb an aerosol-generating substrate and atomize the aerosol-generating substrate to form an aerosol.

[0155] Illustratively, the atomizer assembly 600 has a penetrating microporous structure, and the side of the atomizer assembly 600 where the microporous structure is connected to the liquid storage chamber 420 is a liquid absorption surface, and the side of the atomizer assembly 600 where the microporous structure is connected to the atomization chamber 410 is an atomization surface.

[0156] In some embodiments, the atomizing assembly 600 is provided with an atomizing structure on the atomizing surface. The specific atomizing structure is not limited herein, and may be, for example, a heating wire, etc.

[0157] The base 500 is the primary location where the aerosol-generating substrate is converted into aerosol. It is typically made of a sturdy material to ensure stability during the atomization process. The base 500 provides support for the atomization assembly 600 and forms the atomization chamber 410 , where the aerosol-generating substrate is converted into aerosol.

[0158] The specific structure of the base 500 is not limited here. For example, it can be an integrally formed structure, or it can be assembled from multiple parts.

[0159] Atomization chamber 410 is a space within base 500 that is connected to air outlet passage 430 and serves as the area where the aerosol-forming substrate is atomized into fine particles. During the atomization process, atomization chamber 410 provides the necessary space for the aerosol-forming substrate to be dispersed into tiny aerosol particles by atomization assembly 600.

[0160] The specific structure of the atomizing chamber 410 is determined according to actual conditions and is not limited here.

[0161] In some embodiments, a guide rib is provided in the atomization chamber 410 , and the guide rib can guide the condensed aerosol generating substrate and the un-atomized aerosol generating substrate to the atomization assembly 600 , so as to make full use of the aerosol generating substrate and improve the use efficiency of the aerosol generating substrate.

[0162] The liquid inlet channel 520 is a channel connecting the liquid storage chamber 420 and the atomizer assembly 600 . The atomizer assembly 600 is in liquid communication with the liquid outlet of the liquid inlet channel 520 . In this way, the aerosol-generating substrate can be transported from the liquid storage chamber 420 to the atomizer assembly 600 .

[0163] The balancing channel 560 can play a role in air circulation in the atomization mechanism M11. Its first channel opening 561 is connected to the liquid storage chamber 420, and the second channel opening 562 is connected to the atomization chamber 410. The balancing channel 560 is used to maintain the pressure balance inside the liquid storage chamber 420. The pressure balancing process is as follows:

[0164] When factors such as external air pressure or temperature change, causing the internal air pressure of the liquid storage chamber 420 to exceed the external ambient air pressure, the aerosol-generating substrate or gas in the liquid storage chamber 420 is squeezed out through the balancing channel 560 into the liquid storage structure 900, reducing the air pressure in the liquid storage chamber 420. When the internal air pressure in the liquid storage chamber 420 equals the external ambient air pressure, the aerosol-generating substrate or gas in the liquid storage chamber 420 stops squeezing out. The squeezed-out gas can be discharged to the outside, and the squeezed-out aerosol-generating substrate can be stored in the liquid storage structure 900, thereby reducing leakage.

[0165] When factors such as external air pressure or temperature change, causing the internal air pressure of the liquid storage chamber 420 to be lower than the external ambient air pressure, the external gas or the aerosol generating matrix stored in the liquid storage structure 900 is squeezed into the liquid storage chamber 420 until the internal air pressure of the liquid storage chamber 420 is equal to the external ambient air pressure, and the external gas or the aerosol generating matrix stored in the liquid storage structure 900 stops being squeezed in.

[0166] The liquid storage structure 900 is located on the base 500 and is used to store liquid that has flowed into it. During transportation and storage, due to fluctuations in external air pressure or temperature, when the internal air pressure of the atomization mechanism M11 falls below the external ambient air pressure, the aerosol-forming substrate within the liquid storage chamber 420 may overflow from the balancing channel 560. By connecting the second channel opening 562 of the balancing channel 560 to the liquid storage structure 900, the overflowing aerosol-forming substrate can be directed to the liquid storage structure 900, where it can be stored.

[0167] The specific implementation form of the liquid storage structure 900 to achieve the liquid locking function is not limited here.

[0168] Illustratively, the liquid storage structure 900 is provided with a tortuous and complex liquid guiding groove, which utilizes a maze effect to lock the overflowed aerosol generating matrix.

[0169] Illustratively, the liquid storage structure 900 is provided with a mechanical locking device, which uses a tiny mechanical structure, such as a baffle or a valve, to physically prevent the flow of the aerosol-generating substrate.

[0170] The atomizing device M10 provided in the embodiment of the present disclosure, by providing a balancing channel 560, the two ends of the balancing channel 560 are connected to the liquid storage chamber 420 and the atomizing chamber 410 respectively, which can maintain the air pressure balance inside the liquid storage chamber 420. At the same time, a liquid storage structure 900 with a liquid locking function is provided, and the second channel port 562 of the balancing channel 560 is connected to the liquid storage structure 900. In this way, when factors such as external air pressure or temperature change, causing the internal air pressure of the liquid storage chamber 420 to be greater than the external ambient air pressure, the aerosol generating matrix in the liquid storage chamber 420 is squeezed out to the liquid storage structure 900 through the balancing channel 560. The liquid storage structure 900 can store the aerosol generating matrix and improve the leakage situation. When the internal and external air pressures of the atomizing mechanism M11 tend to be balanced, the aerosol generating matrix on the liquid storage structure 900 can flow back to the liquid storage chamber 420 for normal use through the balancing channel 560. In this way, while solving the leakage problem of the atomizing mechanism M11, it can also reduce the waste of the aerosol generating matrix and improve the user experience.

[0171] In one embodiment, the lowest point of the second channel opening 562 of the balancing channel 560 is not higher than the lowest point of the liquid storage structure 900 .

[0172] Here, the lowest point of the second channel opening 562 of the balancing channel 560 is not higher than the lowest point of the liquid storage structure 900.

[0173] When the internal and external pressures of the atomizing mechanism M11 are balanced, the aerosol-generating substrate leaking into the liquid storage structure 900 can be collected by gravity toward the second channel opening 562 of the balancing channel 560, and then flow back through the balancing channel 560 to the liquid storage chamber 420 for use by the atomizing assembly 600 during atomization. This reduces the amount of aerosol-generating substrate remaining in the liquid storage structure 900 during normal use, thereby reducing waste of aerosol-generating substrate.

[0174] In some embodiments, referring to FIG. 7 and FIG. 8 , the liquid storage structure 900 includes a first liquid pocket area 910 . The first liquid pocket area 910 can store liquid flowing into the first liquid pocket area 910 under the action of capillary force.

[0175] Capillary force refers to the force exerted by liquid to move along the solid surface due to the effect of surface tension at the interface between liquid and solid.

[0176] First liquid-holding area 910 is the region within liquid storage structure 900 used to store liquid. This region utilizes capillary forces to store the aerosol-forming substrate that has flowed into it. First liquid-holding area 910 is designed to utilize the surface tension between the liquid and solid interface to maintain stable storage of the aerosol-forming substrate through capillary action, thereby locking any excess aerosol-forming substrate.

[0177] The specific structure of the first liquid pocket area 910 is not limited here. The first liquid pocket area 910 should have a capillary structure that can provide capillary force to store the liquid flowing into the first liquid pocket area 910.

[0178] For example, the first liquid-collecting area 910 is subjected to special surface treatment to change the chemical properties or physical structure of the surface, such as a hydrophilic coating, so as to enhance the capillary force and thus improve the locking of the aerosol-generating matrix.

[0179] By setting up the first liquid pocket area 910, the capillary phenomenon between the first liquid pocket area 910 structure itself and the liquid is used to store the liquid flowing to the first liquid pocket area 910 using capillary action. There is no need to set up an additional liquid locking structure. The structure is simple and easy to set up, which is conducive to reducing production costs.

[0180] In some embodiments, referring to Figures 7 and 8, the first liquid-collecting area 910 includes a first capillary groove 911 extending along a first direction X. The first capillary groove 911 penetrates the circumferential sidewall of the base 500. The first capillary groove 911 can store liquid flowing into the first capillary groove 911 under the action of capillary force. The second channel opening 562 of the balancing channel 560 is connected to the atomizing chamber 410 through the first liquid-collecting area 910, wherein the first direction X intersects with the second direction Y of the atomizing chamber 410. For convenience of description, the first direction X and the second direction Y refer to the directions shown in Figures 7 and 8. Of course, the first direction X and the second direction Y can also refer to any other directions and are not limited here.

[0181] The first capillary groove 911 is a capillary structure provided within the first liquid collecting area 910. The first capillary groove 911 extends through the circumferential sidewall of the base 500 and can store liquid flowing into the first capillary groove 911 under the action of capillary force. In other words, the first liquid collecting area 910 is connected to the atomization chamber 410 through the first capillary groove 911.

[0182] For example, the first capillary grooves 911 are microgrooves or microchannels. These tiny channels can be formed on the surface of the first liquid-collecting area 910, utilizing the capillary rise of liquid in a small space to capture and transport the aerosol-forming substrate. The microgrooves can be designed by etching, laser processing, or other microfabrication techniques to ensure that the channel size and shape are suitable for the desired capillary action.

[0183] In some embodiments, a first sealant 710 is covered on the outside of the first capillary groove 911, for example, a silicone sealing sleeve, to seal the opening of the first capillary groove 911 toward the side of the base 500. In this way, the first capillary groove 911 only needs to use capillary force to store liquid at the opening close to the side of the base 500.

[0184] The shape of the first capillary groove 911 is not limited here, and can be, for example, rectangular, trapezoidal, or semicircular to meet different design requirements and optimize the capillary force effect.

[0185] The size of the first capillary groove 911 is not limited here. The size of the groove, including width and depth, can be optimized according to the viscosity and surface tension of the aerosol generating substrate.

[0186] The second channel opening 562 of the balancing channel 560 is connected to the atomization chamber 410 through the first liquid pocket area 910. The specific setting position of the balancing channel 560 is not limited here. For example, it can be opened on the base 500, and the balancing channel 560 directly extends to communicate with the first liquid pocket area 910. The balancing channel 560 and the first liquid pocket area 910 can also be connected by a pipe.

[0187] By providing the first capillary groove 911 in the first liquid pocket area 910 , the liquid flowing into the first capillary groove 911 is stored by the capillary force of the first capillary groove 911 , thereby achieving the locking of the aerosol-generating matrix flowing into the first liquid pocket area 910 in the first liquid pocket area 910 .

[0188] In some embodiments, referring to FIG. 7 and FIG. 8 , a portion of the groove wall of the first capillary groove 911 is recessed to form a second capillary groove 912 . The second capillary groove 912 can store liquid flowing into the second capillary groove 912 under the action of capillary force.

[0189] The second capillary groove 912 is a portion of the groove wall of the first capillary groove 911 that is recessed to form a capillary structure.

[0190] In this way, the contact area between the first liquid-carrying area 910 and the aerosol-generating substrate can be increased by the second capillary grooves 912 , thereby improving the liquid-locking effect of the first liquid-carrying area 910 on the aerosol-generating substrate.

[0191] The specific structure of the second capillary groove 912 is not limited here.

[0192] For example, the groove wall of the first capillary groove 911 has a plurality of recessed areas spaced apart along the second direction Y to form a second capillary groove 912. The first capillary groove 911 and the second capillary groove 912 together form a capillary structure with a sawtooth structure at the connection between the first capillary groove 911 and the atomization chamber 410. In this way, when the aerosol generating substrate flows to this point, the aerosol generating substrate fills the sawtooth structure under the action of capillary force to form a liquid film, thereby blocking the subsequent outflow of the aerosol generating substrate from flowing into the atomization chamber 410, and storing the leaked aerosol generating substrate in the first liquid pocket area 910.

[0193] By partially recessing the walls of the first capillary groove 911 to form the second capillary groove 912, the contact area between the first liquid pocket region 910 and the aerosol-generating substrate is increased, thereby enhancing the liquid-locking effect of the first liquid pocket region 910 on the aerosol-generating substrate, resulting in a simple structure. The capillary structure formed by the first capillary groove 911 and the second capillary groove 912 can form a liquid film with the aerosol-generating substrate at the connection point between the first capillary groove 911 and the atomization chamber 410, thereby preventing subsequent outflow of the aerosol-generating substrate from flowing into the atomization chamber 410 and storing the leaked aerosol-generating substrate in the first liquid pocket region 910.

[0194] In some embodiments, referring to FIG. 7 and FIG. 8 , a dimension of the first capillary groove 911 in the second direction Y of the atomizing chamber 410 is no greater than 0.6 mm.

[0195] The dimension of the first capillary groove 911 in the second direction Y of the atomizing chamber 410 is not greater than 0.6 mm, for example, it can be 0.1 mm, 0.15 mm, 0.22 mm, 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, 0.55 mm, 0.6 mm, etc.

[0196] Setting the size of the first capillary groove 911 in the second direction Y of the atomization chamber 410 within the above range is conducive to the occurrence of capillary phenomenon and improves the locking effect of the capillary force, so that the aerosol generating substrate flowing into the first capillary groove 911 is more dissolved to form a liquid surface, thereby effectively locking the aerosol generating substrate that subsequently leaks.

[0197] In some embodiments, referring to FIG. 7 and FIG. 8 , the lowest point of the second channel opening 562 of the balancing channel 560 is not higher than the lowest point of the first capillary groove 911 .

[0198] Here, the lowest point of the second channel opening 562 of the balancing channel 560 is no higher than the lowest point of the first capillary groove 911. Thus, when the internal and external air pressures of the atomizing mechanism M11 are balanced, the aerosol-generating substrate leaking into the first capillary groove 911 can be drawn toward the second channel opening 562 of the balancing channel 560 under the action of gravity, and then flow back through the balancing channel 560 to the liquid storage chamber 420 for use during atomization by the atomizing assembly 600. This reduces the amount of aerosol-generating substrate remaining in the first capillary groove 911 during normal use, thereby reducing waste of aerosol-generating substrate.

[0199] In some embodiments, referring to Figures 7 to 10, the liquid storage structure 900 includes a second liquid pocket area 920, at least part of the second liquid pocket area 920 is located between the side wall of the atomization assembly 600 and the inner wall of the base 500, and the second liquid pocket area 920 can store liquid flowing to the second liquid pocket area 920 under the action of capillary force.

[0200] Second liquid-holding area 920 is a region within liquid storage structure 900 used to store liquid. This region utilizes capillary forces to store the aerosol-forming substrate that has flowed into it. Second liquid-holding area 920 is designed to utilize the surface tension between the liquid and solid interface to maintain stable storage of the aerosol-forming substrate through capillary action, thereby locking any excess aerosol-forming substrate.

[0201] The second liquid pocket area 920 is located between the side wall of the atomizer assembly 600 and the inner wall of the base 500. The micro-pores are formed by the spacing between the side wall of the atomizer assembly 600 and the inner wall of the base 500. Capillary force can also be used to capture and store the aerosol-generating matrix flowing into this area.

[0202] The specific structure of the second liquid collecting area 920 is not limited here.

[0203] Here, it should be noted that since the atomizing assembly 600 has a microporous structure that runs through it, the microporous structure connects the liquid storage chamber 420 with the atomizing chamber 410. When the air pressure inside and outside the atomizing mechanism M11 is balanced, the aerosol generating matrix in the liquid storage chamber 420 will not flow from the microporous structure to the atomizing chamber 410 under the action of capillary force and air pressure. When the atomizing mechanism M11 is in normal use, the external negative pressure can drive the aerosol generating matrix in the atomizing chamber 410 to flow out according to a set amount. When it flows out to the atomizing surface, the aerosol generating matrix is ​​atomized and flows out from the air outlet channel 430 in the form of an aerosol. The aerosol generating matrix will not remain in large quantities in the atomizing chamber 410. However, during transportation and storage, due to changes in the external environment, the aerosol generating matrix in the liquid storage chamber 420 flows out from the microporous structure. At this time, the atomizing assembly 600 is not working and cannot consume these outflowing aerosol generating matrices, resulting in leakage of the aerosol generating matrix.

[0204] The second liquid pocket area 920 can store the aerosol-generating substrate leaking from the microporous structure. Furthermore, since the second liquid pocket area 920 is located between the sidewall of the atomizer assembly 600 and the inner wall of the base 500, the microporous structure is connected to the second liquid pocket area 920. During normal use, the leaked aerosol-generating substrate can flow back into the liquid storage chamber 420 through the microporous structure of the atomizer assembly 600.

[0205] By setting up the second liquid pocket area 920, the capillary phenomenon between the second liquid pocket area 920 structure itself and the liquid is used to store the aerosol generation matrix that cannot be consumed in the atomization mechanism M11 cavity by capillary action. No additional liquid locking structure is required, the structure is simple, the setting is convenient, and it is conducive to reducing the production cost. In some embodiments, the liquid storage structure 900 includes the second liquid pocket area 920, and the balance channel 560 is set at

[0206] The second liquid-holding area 920 facilitates the simplification of the liquid storage structure 900 and reduces production costs. In some cases, such as for the atomization mechanism M11 with high requirements for leak prevention, the liquid storage structure 900 can include a first liquid-holding area 910 and a second liquid-holding area 920, with the balancing channel 560 disposed within the first liquid-holding area 910. The provision of two liquid-holding areas facilitates improving the leak prevention capability of the atomization mechanism M11.

[0207] In some embodiments, referring to Figures 7 to 10, the second liquid pocket area 920 includes a third capillary groove 921, the atomization mechanism M12 includes a first seal 710, the first seal 710 is clamped between the atomization assembly 600 and the base 500, the first seal 710, the atomization assembly 600 and the base 500 define the third capillary groove 921, the second liquid pocket area 920 is connected to the atomization chamber 410, and the second channel opening 562 of the balance channel 560 is connected to the second liquid pocket area 920.

[0208] The first seal 710 is used for sealing the connection between the atomization assembly 600 and the base 500, ensuring that the aerosol generating matrix does not leak during the atomization process, while also helping to maintain the pressure inside the atomization mechanism M11 and prevent the entry of external contaminants.

[0209] The first seal 710 is sandwiched between the atomizer assembly 600 and the base 500. That is, the first seal 710, the atomizer assembly 600 and the base 500 define a "U"-shaped groove, which is the third capillary groove 921. The first seal 710 constitutes the bottom of the third capillary groove 921, and the side wall of the atomizer assembly 600 and the inner wall of the base 500 constitute the groove wall of the third capillary groove 921.

[0210] The specific material of the first sealing member 710 is not limited here. The first sealing member 710 should have a certain elasticity and deform under the squeezing action of the atomizer assembly 600 and the base 500 to fill the gap between the atomizer assembly 600 and the base 500 to achieve a sealing effect. Exemplarily, the first sealing member 710 is a silicone pad.

[0211] The third capillary groove 921 is a capillary structure provided in the second liquid collecting area 920. The third capillary groove 921 can store liquid flowing into the third capillary groove 921 under the action of capillary force.

[0212] The shape of the third capillary groove 921 is not limited here, and can be, for example, rectangular, trapezoidal, or semicircular to meet different design requirements and optimize the capillary force effect.

[0213] The size of the third capillary groove 921 is not limited here. The size of the groove, including width and depth, can be optimized according to the viscosity and surface tension of the aerosol generating substrate.

[0214] Since the third capillary groove 921 is defined by the first sealing member 710 , the atomizing assembly 600 and the base 500 , the shape and size of the third capillary groove 921 are determined by the first sealing member 710 , the atomizing assembly 600 and the base 500 .

[0215] The specific structure of the balancing channel 560 is not limited herein. For example, the balancing channel 560 may be formed by opening a channel in the base 500 that communicates with the second liquid pocket area 920. This facilitates the start of the balancing channel 560. Furthermore, because the base 500 is a rigid structure, external forces do not affect the flow cross-sectional area of ​​the balancing channel 560. Alternatively, the balancing channel 560 may be formed by opening a channel in the first sealing member 710 that communicates with the second liquid pocket area 920.

[0216] Of course, the base 500 and the first sealing member 710 may also be provided with a channel to form the balancing channel 560. By providing the third capillary groove 921 in the second liquid pocket region 920, the liquid flowing into the third capillary groove 921 is stored by the capillary force of the third capillary groove 921, thereby achieving the locking of the aerosol-generating substrate flowing into the second liquid pocket region 920 in the second liquid pocket region 920.

[0217] In some embodiments, referring to FIG. 7 to FIG. 10 , a ventilation groove 711 is provided on the inner wall of the first sealing member 710 , and the ventilation groove 711 and the surface of the atomizing assembly 600 define a balance channel 560 .

[0218] The ventilation groove 711 is a portion of the inner wall of the first sealing member 710 . The ventilation groove 711 is designed to be concave and defines a balance channel 560 together with the surface of the atomizing assembly 600 .

[0219] The ventilation groove 711 and the surface of the atomizer assembly 600 define a balance channel 560 . That is, the surface of the atomizer assembly 600 closes the ventilation groove 711 to form the balance channel 560 .

[0220] It is understandable that the balancing channel 560 is connected to the liquid storage chamber 420 and the atomization chamber 410, that is, both ends of the ventilation groove 711 provided on the inner wall of the first sealing member 710 extend to the liquid storage chamber 420 and the atomization channel respectively, and are connected.

[0221] The setting position of the ventilation groove 711 is not limited here and is determined according to actual conditions.

[0222] For example, the ventilation groove 711 is provided on the first sealing member 710 on the atomizing surface side close to the atomizing assembly 600, and the ventilation groove 711 and the atomizing surface together form the balance channel 560. In this way, the formation of the ventilation groove 711 can be facilitated. By providing the ventilation groove 711 on the inner wall of the first sealing member 710, the ventilation groove 711 and the surface of the atomizing assembly 600 define a balance channel 560.

[0223] The formation of the balancing channel 560 can shorten the setting length of the balancing channel 560 , simplify the structure, and reduce the difficulty of setting the balancing channel 560 .

[0224] In some embodiments, referring to Figures 7 to 10 , the width of the third capillary groove 921 is no greater than 0.6 mm. The width of the third capillary groove 921 is no greater than 0.6 mm, and can be, for example, 0.1 mm, 0.15 mm, 0.22 mm, 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, 0.55 mm, 0.6 mm, etc.

[0225] It should be noted that the width here refers to the distance between the side wall of the atomizing assembly 600 and the inner wall of the base 500 constituting the third capillary groove 921 .

[0226] Setting the size of the third capillary groove 921 within the above range is conducive to the occurrence of capillary phenomenon and improves the locking effect of the capillary force, so that the aerosol generating substrate flowing into the third capillary groove 921 is more dissolved to form a liquid film, thereby effectively locking the subsequent leakage of the aerosol generating substrate.

[0227] In some embodiments, referring to FIG. 7 to FIG. 10 , the lowest point of the second channel opening 562 of the balancing channel 560 is not higher than the lowest point of the third capillary groove 921 .

[0228] Exemplarily, the second channel opening 562 of the balancing channel 560 is disposed in the third capillary groove 921 , and the lowest point of the second channel opening 562 of the balancing channel 560 is flush with the lowest point of the third capillary groove 921 .

[0229] Here, the lowest point of the second channel opening 562 of the balancing channel 560 is no higher than the lowest point of the third capillary groove 921. Thus, when the internal and external air pressures of the atomizing mechanism M11 are balanced, the aerosol-forming substrate leaking into the third capillary groove 921 can be drawn toward the second channel opening 562 of the balancing channel 560 under the action of gravity, and then flow back through the balancing channel 560 to the liquid storage chamber 420 for use during atomization by the atomizing assembly 600. This reduces the amount of aerosol-forming substrate remaining in the third capillary groove 921 during normal use, thereby reducing waste of aerosol-forming substrate.

[0230] In some embodiments, referring to Figures 7 to 11, the base 500 is provided with a first air inlet channel 530, and the first air inlet channel 530 passes through the circumferential side wall of the base 500. The atomization chamber 410 can be connected to the outside of the atomization mechanism M11 through the first air inlet channel 530. In the second direction Y of the atomization mechanism M11, the lowest point of the first air inlet channel 530 is higher than the top surface of the atomization assembly 600.

[0231] The first air inlet channel 530 is a channel opened on the atomizing mechanism M11 for introducing external air. The first air inlet channel 530 connects the atomizing chamber 410 with the outside of the atomizing mechanism M11, which helps to form the airflow required for atomization.

[0232] The lowest point of the first air inlet channel 530 is higher than the top surface of the atomizer assembly 600. In this way, the large-capacity aerosol generating matrix flowing out of the surface of the atomizer assembly 600 is higher than the top surface of the atomizer assembly 600. The inner wall of the base 500 can block the aerosol generating matrix, and a large-capacity aerosol generating matrix can be stored in the atomizer chamber 410.

[0233] It is understandable that the greater the distance between the lowest point of the first air inlet channel 530 and the top surface of the atomizer assembly 600 , the greater the capacity of the base 500 for storing the aerosol generating substrate in the atomizer chamber 410 .

[0234] At the same time, the closer the lowest point of the first air inlet channel 530 is to the top surface of the atomizer assembly 600, the more complete the contact between the external airflow and the atomizing surface of the atomizer assembly 600, and the better the taste of the aerosol produced.

[0235] Therefore, the distance between the lowest point of the first air inlet channel 530 and the top surface of the atomizer assembly 600 needs to be comprehensively considered based on the amount of aerosol-generating substrate, that is, the mouth feel of the aerosol.

[0236] Here, it should be noted that, for the embodiment in which a second liquid pocket area 920 is provided, the second liquid pocket area 920 refers to the section from the horizontal plane of the lowest point of the first air inlet channel 530 to the top surface of the atomization assembly 600, which is formed by the inner wall of the base 500, and the space defined by the third capillary groove 921.

[0237] In some embodiments, the lowest point of the first air inlet channel 530 is no more than 1 mm away from the top surface of the atomizer assembly 600, for example, it can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, etc.

[0238] The shape and size of the first air inlet channel 530 are not limited here, and can be, for example, circular, elliptical, or slit-shaped. The size of the first air inlet channel 530 will affect the air flow rate and atomization effect.

[0239] The positions and number of the first air inlet channels 530 can be distributed on the circumferential side wall of the base 500 according to the size and design requirements of the atomization mechanism M11, and the number can be adjusted as needed.

[0240] The provision of the second channel opening 562 can increase the airflow within the atomizing chamber 410, thereby improving the atomization efficiency of the aerosol-generating substrate. The lowest point of the first air inlet channel 530 is higher than the top surface of the atomizing assembly 600, which can also store a large amount of aerosol-generating substrate within the atomizing chamber 410.

[0241] In some embodiments, referring to FIG. 7 to FIG. 11 , the first air inlet channel 530 is a waist-shaped hole extending along the second direction Y of the atomization mechanism M11 , and the width of the first air inlet channel 530 is no greater than 0.6 mm.

[0242] The width of the first air inlet channel 530 is not greater than 0.6 mm, for example, it can be 0.1 mm, 0.15 mm, 0.22 mm, 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, 0.55 mm, 0.6 mm, etc.

[0243] Setting the size of the first air inlet channel 530 within the above range is conducive to the occurrence of capillary phenomenon, improving the locking effect of the capillary force, so that the aerosol generating substrate flowing into the third capillary groove 921 is more dissolved to form a liquid surface, and the subsequent leakage of the aerosol generating substrate is well locked.

[0244] On the other hand, the first air inlet channel 530 is configured as a kidney-shaped hole extending along the second direction Y of the atomizing mechanism M11. When a large volume of aerosol-generating substrate flows into the atomizing chamber 410, the capillary force in the kidney-shaped hole below the liquid level of the aerosol-generating substrate forms a liquid film, sealing the portion of the kidney-shaped hole below the liquid level of the aerosol-generating substrate, thereby preventing the outflow of the aerosol-generating substrate. At the same time, the portion of the kidney-shaped hole below the liquid level of the aerosol-generating substrate with a capillary structure remains connected to the exterior of the atomizing mechanism M11, thus still guiding external air into the atomizing chamber 410. This simple structure is suitable for situations where a large volume of aerosol substrate flows out.

[0245] In the atomization device M10 for side atomization, the heating element 610 is arranged vertically, and the liquid absorption surface 612 of the heating element 610 is located on the side. An L-shaped lower liquid flow channel is provided in the atomization mechanism M12 to supply liquid. The lower liquid flow channel has a vertical flow channel and a corner flow channel intersecting with the vertical flow channel. The corner flow channel guides the vertically flowing aerosol generating matrix to flow horizontally and contact the liquid absorption surface, thereby achieving liquid supply to the liquid absorption surface located on the side. However, after research, it was found that after the aerosol generating matrix flips and shakes, the bubbles contained in the aerosol generating matrix may move to the corner flow channel. Subsequent bubbles are stuck in the corner flow channel and cannot float up, which will affect the smoothness of subsequent liquid supply.

[0246] Referring to Figures 12-13 , to address this technical issue, the present disclosure provides an atomizing device M10. The atomizing mechanism M12 includes a second housing 400, a base 500, and an atomizing assembly 600. The second housing 400 has an internal air outlet passage 430. The base 500 is disposed within the second housing 400, defining a liquid storage chamber 420 between the base 500 and the second housing 400. The atomizing assembly 600 is disposed on the base 500 and includes an atomizing surface 611 and a liquid suction surface 612. The atomizing surface 611 is non-perpendicular to the central axis of the air outlet passage 430. It is understood that the non-perpendicular arrangement of the atomizing surface 611 of the atomizing assembly 600 and the axis of the air outlet channel 430 means that the atomizing surface 611 and the axis of the air outlet channel 430 can be parallel, or there is a certain acute angle between the two, for example, the angle formed between them is between 0 and 10 degrees, and the naked eye can hardly see that the extension line of the atomizing surface 611 intersects the axis of the air outlet channel 430. In this way, the atomizing assembly 600 is fixed to the base 500, and the atomizing surface 611 is located on the side intersecting the axial direction of the air outlet channel 430, forming an atomizing device M10 with side atomization.

[0247] The base 500 is provided with a liquid inlet channel 520 that communicates with the liquid storage chamber 420, allowing the aerosol-generating substrate to flow directly from the liquid storage chamber 420 into the liquid inlet channel 520. The liquid inlet channel 520 has a channel sidewall 521 facing the atomizer assembly 600. The channel sidewall 521 includes a liquid inlet surface 522 and a sub-sidewall 523 located outside the liquid inlet surface 522. Liquid in the liquid inlet channel 520 can flow through the liquid inlet surface 522 to the atomizer assembly 600, thereby supplying liquid to the atomizer assembly 600.

[0248] Furthermore, the liquid inlet surface 522 remains flush with the sub-sidewall 523, and the liquid inlet surface 522 does not sink relative to the sub-sidewall 523, causing bubbles to become stuck at the liquid inlet surface 522 and affect smooth liquid supply. Furthermore, the liquid inlet surface 522 area is smaller than the area of ​​the liquid aspiration surface 612. It can be understood that the liquid inlet surface area is the effective liquid inlet area on the liquid inlet surface 522. Part of the liquid inlet surface 522 allows liquid to pass through, while another part blocks liquid from passing through. Since the liquid inlet surface area is small, there are no large holes on the liquid inlet surface 522, and bubbles within the aerosol generating matrix will not become stuck at the liquid inlet surface 522. In this way, by preventing the liquid inlet surface 522 from sinking and preventing the liquid inlet surface 522 from accumulating too much, bubbles can be prevented from being stuck at the liquid inlet surface 522 and blocking the aerosol-generating matrix from flowing to the atomizing component 600, thereby improving the smoothness of liquid supply and preventing the atomizing device M10 from burning dry or having a burnt smell.

[0249] Furthermore, a plurality of micropores 541 are formed on the liquid inlet surface 522, connecting the liquid inlet channel with the atomizer assembly 600. The combined opening area of ​​all micropores 541 is smaller than the area of ​​the liquid aspiration surface 612, resulting in a smaller effective liquid inlet surface area of ​​the liquid inlet surface 522, thereby preventing bubbles from becoming trapped at the liquid level. Furthermore, the micropores 541 have a very small diameter, which blocks the passage of bubbles from the aerosol-generating matrix that migrate to the micropores 541. This allows bubbles in the aerosol-generating matrix to smoothly rise to the top along the linear liquid inlet channel 520, preventing bubbles from becoming trapped at the liquid inlet surface 522 and affecting liquid supply.

[0250] Optionally, the diameter of the micropore 541 is 0.4mm-0.8mm, for example, the diameter of the micropore 541 is 0.5mm, and liquid can be supplied through the capillary phenomenon of multiple micropores 541. At the same time, the small diameter of the micropore 541 blocks the entry of bubbles, preventing bubbles from getting stuck at the liquid inlet surface 522 and causing poor liquid supply.

[0251] Alternatively, the channel side wall 521 of the liquid inlet channel 520 facing the atomization assembly 600 is constructed as a straight side wall, and there is no depression on the channel side wall 521, so bubbles are not easily trapped.

[0252] According to some embodiments of the present disclosure, the atomizing assembly 600 includes a heating element 610, which is a non-liquid storage component and does not have the ability to store liquid. The heating element 610 has a liquid absorption surface 612 and an atomizing surface 611. At least one straight receiving channel 542 is provided on the heating element 610, which passes through the liquid absorption surface 612 and the atomizing surface 611. In this way, the liquid is guided to flow to the atomizing surface 611 through the straight receiving channel 542. When the straight receiving channel 542 is provided, a plurality of evenly arranged straight receiving channels 542 can be provided as needed. Compared with the disordered arrangement of holes in the porous structure, by providing a plurality of orderly arranged straight receiving channels 542 on the non-liquid storage component, the liquid supply rate can be more effectively controlled and the liquid supply performance can be improved. For example, the heating element is a glass component, and a plurality of orderly arranged straight receiving channels 542 are provided on the glass.

[0253] In this case, the heating element 610 does not have the ability to store liquid, and needs to maintain continuous liquid supply to the heating element 610 from the liquid inlet channel 520 through the liquid inlet surface 522. In the atomization mechanism M12 provided in the present disclosure, the liquid inlet surface 522 is flush with the sub-side wall 523, and micropores 541 are formed on the liquid inlet surface 522. The liquid inlet surface 522 will not be recessed relative to the sub-side wall 523 to prevent bubbles from being stuck, and the micropores 541 will also block the entry of bubbles, thereby preventing bubbles from being stuck at the liquid inlet surface 522 and affecting the liquid supply, thereby ensuring smooth liquid supply to the heating element 610 and preventing the heating element 610 from dry burning.

[0254] According to some embodiments of the present disclosure, the base 500 has a partition 540, a liquid inlet channel 520 is formed on one side of the partition 540, and an atomization assembly 600 is installed on the other side of the partition 540. In this way, the partition 540 is used to separate the base 500 to form the liquid inlet channel 520, and the atomization assembly 600 is set on the other side of the partition 540 for atomizing the aerosol to generate the matrix.

[0255] According to some embodiments of the present disclosure, the side of the partition 540 facing the liquid inlet channel 520 is at least partially constructed to form a liquid inlet surface 522, and a number of micropores 541 are provided on the liquid inlet surface 522 to connect the liquid inlet channel and the atomizing assembly 600. In this way, the liquid inlet channel and the atomizing assembly 600 are connected by providing the micropores 541 to achieve liquid supply. Specifically, the side of the partition 540 facing the liquid inlet channel 520 is a channel sidewall 521, and the channel sidewall 521 includes a liquid inlet surface 522 provided with micropores 541 and a sub-sidewall 523 located on the periphery of the liquid inlet surface 522. The sub-sidewall 523 is flush with the liquid inlet surface 522 to prevent the liquid inlet surface 522 from being recessed relative to the sub-sidewall 523 and bubbles from being stuck at the liquid inlet surface 522. At the same time, the micropores 541 are provided on the liquid inlet surface 522 to allow liquid to pass through while blocking bubbles from entering the micropores 541, further preventing bubbles from being stuck at the liquid inlet surface 522, thereby ensuring smooth liquid supply.

[0256] For example, the side of the partition 540 facing the liquid inlet channel 520 is constructed as a flat surface, and a number of micropores 541 are opened at the position corresponding to the partition 540 and the atomization assembly 600. The area where the micropores 541 are opened is defined as the liquid inlet surface 522, and the other areas are defined as the sub-side wall 523.

[0257] Specifically in some embodiments, the atomization assembly 600 includes a heating element 610, which has an atomization surface 611 and a liquid absorption surface 612. The liquid absorption surface 612 is arranged to fit the micropores 541 and the partition 540. In this way, the heating element 610 and the partition 540 are fitted together, and the liquid flows through the micropores 541 on the partition 540 to the liquid absorption surface 612 of the heating element 610, thereby realizing liquid supply to the heating element 610.

[0258] Optionally, the heating element 610 is a porous structure, such as ceramic, which can store the absorbed aerosol-generating matrix and improve the stability of the liquid supply. Alternatively, the heating element 610 is a non-liquid storage component, such as a glass component, and the heating element 610 is provided with at least one straight receiving channel 542 that passes through the liquid absorption surface 612 and the atomization surface 611. In this way, the liquid is guided to flow toward the atomization surface 611 through the straight receiving channel 542. When the straight receiving channel 542 is provided, multiple evenly arranged straight receiving channels 542 can be provided as needed. Compared with the disordered arrangement of holes in the porous structure, by providing multiple orderly arranged straight receiving channels 542 on the glass, the liquid supply rate can be more effectively controlled and the liquid supply performance can be improved.

[0259] In other embodiments, the atomization assembly 600 includes a heating element 610 and a liquid absorbing member 520. The heating element 610 has an atomizing surface 611 and a liquid absorbing surface 612 opposite the atomizing surface 611. The liquid absorbing surface 612 is provided between the liquid absorbing surface 612 and the partition 540, corresponding to a plurality of micropores 541. The aerosol-generating substrate flowing in from the micropores 541 is absorbed, stored, and transmitted to the heating element 610 by the liquid absorbing member 520. When the heating element 610 generates heat, it atomizes the aerosol-generating substrate absorbed within itself and produces an atomized aerosol at the atomizing surface 611. In this manner, the liquid absorbing member 520 is provided downstream of the micropores 541 to store the aerosol-generating substrate.

[0260] Optionally, the heating element 610 is a porous structure, such as ceramic, which can store the absorbed aerosol-generating matrix and improve the stability of the liquid supply. Alternatively, the heating element 610 is a non-liquid storage component, such as a glass component, and the heating element 610 is provided with at least one straight receiving channel 542 that passes through the liquid absorption surface 612 and the atomization surface 611. In this way, the liquid is guided to flow toward the atomization surface 611 through the straight receiving channel 542. When the straight receiving channel 542 is provided, multiple evenly arranged straight receiving channels 542 can be provided as needed. Compared with the disordered arrangement of holes in the porous structure, by providing multiple orderly arranged straight receiving channels 542 on the glass, the liquid supply rate can be more effectively controlled and the liquid supply performance can be improved.

[0261] Optionally, the absorbent member 520 is absorbent cotton, and the absorbent member 520 includes but is not limited to ceramics, glass, quartz or fiber, which can store more aerosol generating matrix, continuously provide a certain amount of aerosol generating matrix for the heating element 610, and prevent the heating element 610 from dry burning.

[0262] 14-15 , according to other embodiments of the present disclosure, the atomizer assembly 600 at least partially passes through the partition 540 and faces the liquid inlet channel 520. The portion of the atomizer assembly 600 facing the liquid inlet channel 520 is configured as a liquid inlet surface 522. Thus, the atomizer assembly 600 is at least partially disposed through the partition 540 so that at least a portion of the atomizer assembly 600 is in direct contact with the aerosol-generating matrix in the liquid inlet channel 520 for liquid supply. The surface of the atomizer assembly 600 facing the liquid inlet channel 520 is equivalent to the liquid inlet surface 522. The sidewall of the partition 540 adjacent to the liquid inlet surface 522 is a sub-sidewall 523. The liquid inlet surface 522 is flush with the sub-sidewall 523. The liquid inlet surface 522 allows liquid to flow through, and the liquid inlet surface 522 will not be recessed relative to the sub-sidewall 523 to trap bubbles, thereby ensuring smooth liquid supply.

[0263] Furthermore, at least one receiving channel 542 communicating with the liquid inlet channel 520 is defined on the partition 540. The atomizer assembly 600 at least partially extends into the receiving channel 542 and is flush with the side of the partition 540 facing the liquid passage. The side of the atomizer assembly 600 flush with the partition 540 is configured as the liquid inlet surface 522. Thus, by defining the receiving channel 542 on the partition 540 and filling the receiving channel 542 with the atomizer assembly 600, the channel sidewall 521 of the liquid inlet channel 520 remains flat due to the filling of the atomizer assembly 600, preventing the aerosol-generating substrate in the liquid inlet channel 520 from carrying bubbles into the receiving channel 542 of the partition 540, and preventing bubbles from getting stuck in the receiving channel 542 and affecting the liquid supply.

[0264] At the same time, a number of micropores 541 are formed on the surface of the atomizing component 600 facing the liquid inlet channel 520, and it is constructed as a liquid inlet surface 522. The aerosol generating matrix in the liquid inlet channel 520 can flow to the atomizing surface 611 through the micropores 541 on the atomizing component 600, thereby realizing the liquid supply to the atomizing surface 611 and the atomization of the aerosol generating matrix.

[0265] Specifically, in one embodiment, the atomizing assembly 600 includes a heating element 610, which has an atomizing surface 611 and a liquid absorbing surface 612. The side of the heating element 610 with the liquid absorbing surface 612 at least partially extends into the accommodating channel 542. The liquid absorbing surface 612 is at least partially flush with the side of the partition 540 facing the liquid passage and is constructed as the liquid inlet surface 522. In this way, the accommodating channel 542 on the partition 540 is filled with the heating element 610, so that the channel sidewall 521 of the liquid inlet channel 520 remains flat. The aerosol generating matrix in the liquid inlet channel 520 is in direct contact with the portion of the heating element 610 extending into the accommodating channel 542 for liquid supply. During the liquid supply process, bubbles in the aerosol generating matrix can float to the top of the liquid storage chamber 420 along the flat channel sidewall 521 and will not get stuck at the liquid inlet surface 522, thereby improving the smoothness of liquid supply.

[0266] Optionally, the heating element 610 is a porous structure, such as ceramic, which can store the absorbed aerosol-generating matrix and improve the stability of the liquid supply. The ceramic at least partially extends into the accommodating channel 542 and the surface facing the liquid inlet channel 520 is constructed as a liquid surface. The liquid surface has a porous structure of ceramic, which is equivalent to forming a number of micropores 541 on the liquid surface, and liquid supply is achieved through the micropores 541.

[0267] Alternatively, the heating element 610 is a non-liquid storage element, for example, the heating element 610 is a glass element, and the heating element 610 is provided with at least one straight receiving channel 542 that passes through the liquid absorption surface 612 and the atomizing surface 611. In this way, the liquid is guided to flow to the atomizing surface 611 through the straight receiving channel 542. When the straight receiving channel 542 is provided, a plurality of evenly arranged straight receiving channels 542 can be provided as needed. Compared with the disordered arrangement of holes in the porous structure, by providing a plurality of orderly arranged straight receiving channels 542 on the glass, the liquid supply rate can be more effectively controlled and the liquid supply performance can be improved. At the same time, the glass element at least partially extends into the receiving channel 542 and the surface facing the liquid inlet channel 520 is constructed as a liquid surface. The straight receiving channel 542 opening of the glass element is provided on the liquid surface, which is equivalent to forming a plurality of micropores 541 on the liquid surface, and liquid supply is achieved through the micropores 541.

[0268] In another embodiment, the atomizing assembly 600 includes a heating element 610 and a liquid absorbing member 520. The heating element 610 has an atomizing surface 611 and a liquid absorbing surface 612. The liquid absorbing member 520 is partially disposed between the liquid absorbing surface 612 and the partition 540. Another portion of the liquid absorbing member 520 extends into the receiving channel 542 and is flush with the side of the partition 540 facing the liquid flow channel. The side of the liquid absorbing member 520 flush with the partition 540 is configured as a liquid inlet surface 522. In this way, after the aerosol-generating substrate flows from the liquid storage chamber 420 into the liquid inlet channel 520, it can directly contact the liquid absorbing member 520 flush with the partition 540, and then flow through the liquid absorbing member 520 to the heating element 610, achieving liquid supply. At the same time, at least a portion of the liquid absorbing member 520 extends into the accommodating channel 542 to fill the accommodating channel 542, making the channel sidewall 521 of the liquid inlet channel 520 flat, thereby preventing depressions on the channel sidewall 521 from trapping bubbles in the aerosol generating matrix.

[0269] Optionally, the heating element 610 is a porous structure, such as ceramic, which can store the absorbed aerosol-generating matrix and improve the stability of the liquid supply. Alternatively, the heating element 610 is a non-liquid storage component, such as a glass component, and the heating element 610 is provided with at least one straight receiving channel 542 that passes through the liquid absorption surface 612 and the atomization surface 611. In this way, the liquid is guided to flow toward the atomization surface 611 through the straight receiving channel 542. When the straight receiving channel 542 is provided, multiple evenly arranged straight receiving channels 542 can be provided as needed. Compared with the disordered arrangement of holes in the porous structure, by providing multiple orderly arranged straight receiving channels 542 on the glass, the liquid supply rate can be more effectively controlled and the liquid supply performance can be improved.

[0270] Optionally, the absorbent member 520 is absorbent cotton, and the absorbent member 520 includes but is not limited to ceramics, glass, quartz or fiber, which can store more aerosol generating matrix, continuously provide a certain amount of aerosol generating matrix for the heating element 610, and prevent the heating element 610 from dry burning.

[0271] Furthermore, the liquid absorbing part 520 includes a first liquid absorbing part 621 and a second liquid absorbing part 622 arranged on the first liquid absorbing part 520, the first liquid absorbing part 621 is arranged between the partition 540 and the liquid absorbing surface 612, the second liquid absorbing part 622 fills the accommodating channel 542 and remains flush with the sub-side wall 523 of the side wall facing the liquid inlet channel 520, so that the accommodating channel 542 on the partition 540 is filled by the second liquid absorbing part 622.

[0272] Furthermore, the orthographic projection of the first liquid suction portion 621 toward the second liquid suction portion 622 covers and extends beyond the second liquid suction portion 622, meaning that the first liquid suction portion 621 has a larger area. The larger first liquid suction portion 621 is installed between the partition 540 and the heating element 610, providing a more stable installation. Furthermore, a retaining groove 543 is provided on the side of the partition 540 facing the liquid suction surface 612, communicating with the accommodating channel 542. The second liquid suction portion 622 is retained within the retaining groove 543, further limiting the installation position of the atomizer assembly 600 through the retaining groove 543 on the partition 540, ensuring installation stability.

[0273] According to other embodiments of the present disclosure, the side of the partition 540 facing the liquid inlet channel 520 is at least partially constructed to form a liquid inlet surface 522, the atomizer assembly 600 at least partially passes through the partition 540 and faces the liquid inlet channel 520, and the portion of the atomizer assembly 600 facing the liquid inlet channel 520 is constructed as the liquid inlet surface 522, so that the liquid inlet surface 522 is formed on the partition 540, and the atomizer assembly 600 is at least partially passed through the partition 540 to form a liquid inlet surface 522 on the atomizer assembly 600.

[0274] For example, the partition 540 is provided with at least one receiving channel 542 communicating with the liquid inlet channel 520. The atomizer assembly 600 at least partially extends into the receiving channel 542 and is flush with the side of the partition 540 facing the liquid passage. The side of the atomizer assembly 600 flush with the partition 540 is configured as a liquid inlet surface 522. Meanwhile, the partition 540 is provided with a plurality of micropores 541 surrounding the receiving channel 542 to form another liquid inlet surface 522. In this way, liquid can be supplied not only through the liquid inlet surface 522 where the plurality of micropores 541 on the partition 540 are located, but also through the liquid inlet surface 522 formed by the atomizer assembly 600 passing through the partition 540, thereby providing a larger liquid supply area. At the same time, the liquid inlet surface 522 on the partition 540 is flush with the sub-side wall 523 on the partition 540, and the liquid inlet surface 522 on the atomizer assembly 600 is also flush with the sub-side wall 523. In this way, both liquid inlet surfaces 522 and the sub-partition walls remain flush, forming a flat channel side wall 521, preventing the presence of depressions at the liquid inlet surface 522 and the resulting bubbles from being trapped, thereby ensuring smooth liquid inflow. At the same time, the micropores 541 on the liquid inlet surface 522 allow liquid to pass through while blocking bubbles from entering the micropores 541, further preventing bubbles from being trapped at the liquid inlet surface 522 and further ensuring smooth liquid supply.

[0275] The specific details of the liquid inlet surface 522 on the partition 540, the specific details of the liquid inlet surface 522 on the atomizing assembly 600, and the configuration of the atomizing assembly 600 are similar to those in the other embodiments described above and are not described in detail here.

[0276] Referring to Figure 16, according to some embodiments of the present disclosure, the liquid inlet channel 520 has a curved inner wall 524, the opposite ends of the curved inner wall 524 are spaced apart from each other in the axial direction, and the channel side wall 521 is connected between the opposite ends of the curved inner wall 524 in the axial direction. In this way, the liquid inlet channel 520 is formed by enclosing the curved inner wall 524 and the flat channel side wall 521. The entire inner wall of the liquid inlet channel 520 is smooth and smooth, which facilitates the smooth liquid flow of the aerosol-generating matrix.

[0277] The power supply mechanism M11 is used to power the atomizing mechanism M12. When the atomizing device M10 is powered on, it heats the atomized aerosol to generate the matrix. The electronic atomizing device uses the atomizing device M10 described in any of the above embodiments and has the same technical effects as the atomizing device M10 described above, which is not limited here.

[0278] An embodiment of the present disclosure provides an atomization device M10. By setting a second sealing member 720, when the atomization assembly 600 is connected to the power supply mechanism M11, the second sealing member 720 is sealed between the third end face 250 and the second end face 510, and the second air inlet channel 210 and the first air inlet channel 530 are connected through the sealing member channel 721 of the second sealing member 720, which has a good sealing effect, the airflow is not easy to leak and is easy to control, and the space through which the airflow flows is small, the friction resistance is small, and it is not easy to generate noise, and the air pressure distribution is relatively uniform, which helps to improve the user experience of the atomization device M10.

[0279] 17 , 18 and 19 , the atomizer device M10 of the embodiment of the present disclosure includes a power supply mechanism M11, an atomizer assembly 600 and a second seal 720. Referring to FIG. 20 and 21 , the power supply mechanism M11 is provided with a second air inlet channel 210; the atomizer assembly 600 is provided with a first air inlet channel 530, and the atomizer assembly 600 is connected to the power supply mechanism M11; the second seal 720 is sealed between the power supply mechanism M11 and the atomizer assembly 600, and the second seal 720 is provided with a seal channel 721 to connect the second air inlet channel 210 and the first air inlet channel 530.

[0280] In the embodiment of the present disclosure, the atomization device M10 includes an air inlet. In some examples, the air inlet is arranged in the atomization mechanism M12. The air inlet is an opening of the first air inlet channel 530 located on the outer surface of the atomization mechanism M12. The air flow enters the atomization device M10 from the air inlet of the first air inlet channel 530, and flows through the first air inlet channel 530, the atomization chamber 410 and the air outlet channel 430 in sequence. The first air inlet channel 530 is also connected to the second air inlet channel 210 through the sealing channel 721. The air flow flowing in the first air inlet channel 530 can cause the air pressure in the second air inlet channel 210 to change, thereby triggering the air flow sensor 830 connected to the second air inlet channel 210.

[0281] The first air inlet channel 530 may include a first channel section and a second channel section, wherein the first channel section is provided with an air inlet. The first channel section is connected to the sealing channel 721, and the second channel section is connected to the atomizing chamber 410 via the sealing channel 721. Alternatively, the first channel section is connected to the atomizing chamber 410, and the second channel section is connected between the first channel section and the sealing channel 721.

[0282] In other examples, the air inlet is arranged in the power supply mechanism M11, and the air inlet is the opening of the second air inlet channel 210 located on the outer surface of the power supply mechanism M11. The airflow enters the atomization device M10 from the air inlet of the second air inlet channel 210, and flows through the second air inlet channel 530, the sealing channel 721, the first air inlet channel 530, the atomization chamber 410 and the air outlet channel 430 in sequence. The airflow flowing in the second air inlet channel 210 can cause air pressure changes, thereby triggering the airflow sensor 830 connected to the second air inlet channel 210.

[0283] In the embodiment of the present disclosure, the power supply mechanism M11 may include power supply components, such as batteries, conductive interfaces, etc. The power supply mechanism M11 may also include control components, such as circuit boards, controllers, sensors, etc. For example, referring to Figure 21, the sensor may include an airflow sensor 830, which is used to sense the airflow flow in the second air inlet channel 210. The controller responds to the sensing result of the airflow sensor 830 to control the start-up of the atomization device M10.

[0284] In the embodiment of the present disclosure, the atomizing assembly 600 may include a accommodating chamber for accommodating the atomizing medium. The atomizing assembly 600 may also include an atomizer, which is arranged in the atomizing chamber 410. The atomizer atomizes the atomizing medium under the drive of the power supply assembly and the control assembly. The atomizer may be an ultrasonic type, an electric heating type, etc.

[0285] In the disclosed embodiment, the connection between the atomizer assembly 600 and the power supply mechanism M11 can be a non-detachable connection such as bonding, welding, riveting, etc.; it can also be a detachable connection such as snap connection, threaded connection, fastener connection, magnetic connection, etc. It can be understood that the atomizer assembly 600 and the power supply mechanism M11 adopt a detachable connection, so that the atomizer assembly 600 as a consumable can be easily replaced, which has good environmental and economic benefits. For example, the atomizer assembly 600 is magnetically connected to the power supply mechanism M11.

[0286] In the disclosed embodiment, the power supply mechanism M11 may include a third end surface 250, and the second air inlet channel 210 may include an opening provided at the third end surface 250. The atomizer assembly 600 may include a second end surface 510, and the first air inlet channel 530 may include an opening provided at the second end surface 510. When the atomizer assembly 600 is connected to the power supply mechanism M11, the third end surface 250 and the second end surface 510 are opposite to each other, so that the second air inlet channel 210 and the first air inlet channel 530 are connected via the sealing member channel 721 of the second sealing member 720.

[0287] In the disclosed embodiment, the first air inlet channel 530 is an airflow path connecting the air inlet and air outlet of the atomizer assembly 600. The air inlet of the first air inlet channel 530 is located on the second end surface 510, and the air outlet of the first air inlet channel 530 is located at the end of the atomizer assembly 600 away from the power supply mechanism M11. The portion of the atomizer assembly 600 with the air outlet can be used as the nozzle of the atomizer device M10.

[0288] In the embodiment of the present disclosure, the second sealing member 720 is sealingly arranged between the atomizing assembly 600 and the power supply mechanism M11, that is, the second sealing member 720 isolates the gap between the third end face 250 and the second end face 510 relative to the second air inlet channel 210 and the first air inlet channel 530 through close cooperation with the atomizing assembly 600 and the power supply mechanism M11, and the second air inlet channel 210 and the first air inlet channel 530 cannot be connected to the outside world through the gap between the third end face 250 and the second end face 510.

[0289] In the embodiment of the present disclosure, the second seal 720 has multiple possible connection forms. The second seal 720 can be connected to the power supply mechanism M11 and tightly fit on the surface of the atomizer assembly 600; the second seal 720 can also be connected to the atomizer assembly 600 and tightly fit on the surface of the power supply mechanism M11; or, the second seal 720 is respectively connected to the power supply mechanism M11 and the atomizer assembly 600.

[0290] In the embodiment of the present disclosure, the tight fit between the second seal 720 and the power supply mechanism M11 can be the fit between the second seal 720 and the third end face 250, or the fit between the second seal 720 and other parts of the power supply mechanism M11; accordingly, the tight fit between the second seal 720 and the atomization assembly 600 can be the fit between the second seal 720 and the second end face 510, or the fit between the second seal 720 and other parts of the atomization assembly 600.

[0291] In the disclosed embodiment, the second seal 720 has a variety of possible structural forms and layout positions. In one example, the second seal 720 is located between the third end face 250 and the second end face 510. The second seal 720 can also extend toward the peripheral side of the power supply mechanism M11 and / or the atomizer assembly 600 to be sleeved on the power supply mechanism M11 and / or the atomizer assembly 600. In another example, the second seal 720 is accommodated in the power supply mechanism M11, and the second end face 510 of the atomizer assembly 600 is in contact with the third end face 250 of the power supply mechanism M11. The side of the second seal 720 close to the atomizer assembly 600 is also in contact with the second end face 200, that is, the second end face 510 is in contact with the second seal 720 and the third end face 250, respectively.

[0292] In another example, part of the second seal 720 is accommodated in the power supply mechanism M11, and the other part protrudes from the third end face 250 and is combined with the atomization assembly 600, that is, the two ends of the second seal 720 are respectively connected to the power supply mechanism M11 and the atomization assembly 600.

[0293] In the disclosed embodiment, the second sealing member 720 can be a split structure or an integrated structure. For example, the second sealing member 720 is integrally formed from an elastic material such as rubber. It is understood that the elastically configured second sealing member 720 can improve the tightness of the connection with the atomizer assembly 600 / power supply mechanism M11 through elastic deformation, thereby improving the sealing effect.

[0294] In the disclosed embodiment, the sealing member channel 721 connects the first air inlet channel 530 and the second air inlet channel 210. The sealing member channel 721 may be a constant diameter hole, a variable diameter hole, a stepped hole, etc. The radial cross-section of the sealing member channel 721 may be circular, elliptical, rectangular, square, triangular, rhombus, regular hexagonal, trapezoidal, etc. The extension axis of the sealing member channel 721 may be a straight line, a curve, a spiral, etc. For example, the sealing member channel 721 is provided in the middle of the second sealing member 720, with its extension axis arranged in the direction relative to the third end surface 250 and the second end surface 510. The radial cross-section of the sealing member channel 721 is an elongated strip.

[0295] The technical solution provided by the embodiment of the present disclosure comprises a power supply mechanism M11 and an atomizer assembly 600. The power supply mechanism M11 defines a second air inlet channel 210, and the atomizer assembly 600 defines a first air inlet channel 530. When the atomizer assembly 600 is connected to the power supply mechanism M11, the third end face 250 of the power supply mechanism M11 is opposite to the second end face 510 of the atomizer assembly 600, so that air flows through the second air inlet channel 210 and the first air inlet channel 530.

[0296] On this basis, the atomization device M10 is provided with a second sealing member 720, which is sealed between the power supply mechanism M11 and the atomization assembly 600, thereby blocking the gap between the power supply mechanism M11 and the atomization assembly 600. The second sealing member 720 is provided with a sealing member channel 721, and the second air inlet channel 210 and the first air inlet channel 530 are connected through the sealing member channel 721, which has a good sealing effect.

[0297] Compared with the technical solution in which there may be a gap at the connection between the atomization assembly 600 and the power supply mechanism M11, resulting in air leakage and uneven air pressure distribution, the setting of the second seal 720 reduces the possibility of air leakage and limits the air flow to a smaller space, resulting in a more uniform air pressure distribution.

[0298] Compared with the technical solution in which the gap between the atomization assembly 600 and the power supply mechanism M11 is used as an airflow channel, the airflow passes through a larger area, is subject to greater friction resistance, is difficult to control, and is prone to generating narrow gap noise, the setting of the second seal 720 reduces the resistance to the airflow and reduces the area of ​​the airflow channel, making the airflow easy to control and less likely to generate noise.

[0299] In addition, due to the setting of the second seal 720, the design of the atomization device M10 is less affected by the gap between the atomization assembly 600 and the power supply mechanism M11, and the design is more flexible. The airflow and resistance can also be controlled by flexibly designing the cross-sectional area of ​​the seal channel 721, which helps to improve the user experience of the atomization device M10.

[0300] To improve the sealing effect, referring to Figures 20 and 21, in some possible embodiments of the present disclosure, the second air inlet channel 210 includes an airflow cavity 220, and the sealing member channel 721 is located within the airflow cavity 220. With this arrangement, the airflow cavity 220 serves as the larger portion of the second air inlet channel 210, and the sealing member channel 721 is disposed within the airflow cavity 220, which helps reduce the assembly precision required for the second sealing member 720 and the power supply mechanism M11, thereby facilitating assembly of the second sealing member 720 and the power supply mechanism M11.

[0301] 20 and 21 , in some possible embodiments of the present disclosure, the second sealing member 720 includes a first structural portion 722 . The first structural portion 722 is disposed in the airflow cavity 220 and fits against the inner peripheral wall of the airflow cavity 220 .

[0302] In some examples, the airflow cavity 220 can be provided in the third end surface 250 of the power supply mechanism M11, i.e., the airflow cavity 220 is formed by a recess in the third end surface 250. In other examples, the airflow cavity 220 can also be provided on the side of the power supply mechanism M11 facing away from the third end surface 250. Furthermore, the airflow cavity 220 can also be provided inside the power supply mechanism M11, connected to the third end surface 250 by the second air inlet passage 210. In this technical solution, the second sealing member 720 is located outside the airflow cavity 220.

[0303] In the embodiment of the present disclosure, the airflow chamber 220 can be used as the airflow sensing chamber of the atomization device M10 to connect to the airflow sensor 830. When the user inhales through the first air inlet channel 530, the airflow flows from the airflow chamber 220 to the first air inlet channel 530 to form a negative pressure in the airflow chamber 220, thereby triggering the airflow sensor 830.

[0304] In the disclosed embodiment, the second sealing member 720 includes a first structural portion 722 that extends into the airflow chamber 220 to facilitate mounting the second sealing member 720 to the power supply mechanism M11. On one hand, the second sealing member 720 enhances the airtight seal of the airflow chamber 220 and improves the stability of the air pressure. On the other hand, the first structural portion 722 that extends into the airflow chamber 220 reduces the volume of the airflow chamber 220, facilitating uniform airflow distribution. Both aspects enhance the air pressure and stability of the airflow, thereby facilitating triggering the airflow sensor 830.

[0305] In the disclosed embodiment, the first structural portion 722 may be partially or entirely disposed within the airflow cavity 220. The first structural portion 722 may be spaced apart from or partially aligned with the bottom wall of the airflow cavity 220 (the inner wall opposite the second end surface 510). For example, the first structural portion 722 is entirely disposed within the airflow cavity 220, and the surface of the first structural portion 722 adjacent to the second end surface 510 is flush with the third end surface 250.

[0306] In some possible embodiments, the third end face 250 of the power supply mechanism M11 is fitted with the second end face 510 of the atomizer assembly 600, and the surface of the second seal 720 is flush with the third end face 250 and the second end face 510, that is, the second end face 510 is fitted with the third end face 250 and the second seal 720 respectively to reduce the gap between the power supply mechanism M11 and the atomizer assembly 600.

[0307] In the disclosed embodiment, the first structural portion 722 is aligned with the inner peripheral wall of the airflow cavity 220. Specifically, the outer peripheral wall of the first structural portion 722 and the inner peripheral wall of the airflow cavity 220 have similar structures and dimensions, enabling a close fit. For example, the outer peripheral contour of the third end surface 250 and the outer peripheral contour of the airflow cavity 220 are both rectangular, and both employ an interference fit.

[0308] In the disclosed embodiment, an annular protrusion is further provided on at least one of the outer peripheral wall of the first structural portion 722 and the inner peripheral wall of the airflow cavity 220 to further enhance the sealing effect. The annular protrusion may be one or more, with multiple annular protrusions spaced apart along the axial direction of the sealing member channel 721.

[0309] For example, a second sealing ring 727 is disposed around the outer peripheral wall of the first structural portion 722. The second sealing ring 727 is made of an elastic material, such as rubber. When the first structural portion 722 is assembled to the airflow chamber 220, the second sealing ring 727 elastically deforms to closely fit the inner peripheral wall of the airflow chamber 220.

[0310] It can be understood that the close combination of the first structural part 722 and the airflow chamber 220 can, on the one hand, provide a good airtight seal for stable flow of the airflow; on the other hand, it can also provide dustproof, leakproof, soundproof and other functions, for example, preventing the atomized medium of the atomization component 600 from flowing into the power supply mechanism M11.

[0311] The technical solution provided by the embodiment of the present disclosure sets the first structural part 722 in the airflow cavity 220, and makes the first structural part 722 fit with the inner wall of the peripheral side of the airflow cavity 220, and the two have a large contact area, thereby isolating the airflow cavity 220 relative to the gap between the power supply mechanism M11 and the atomization assembly 600 to provide good sealing performance.

[0312] In order to improve the connection stability, referring to Figures 28 and 29, in some possible embodiments of the present disclosure, the power supply mechanism M11 is provided with a first limiting surface 221, and the second sealing member 720 is provided with at least one elastic limiting portion 728, and the elastic limiting portion 728 has a second limiting surface 7281. When the second sealing member 720 is assembled on the power supply mechanism M11, the first limiting surface 221 and the second limiting surface 7281 abut against each other at least along the assembly direction of the power supply mechanism M11 and the second sealing member 720.

[0313] In the disclosed embodiment, the elastic limiting portion 728 may be an elastic buckle, an elastic boss, or the like. The elastic limiting portion 728 is capable of elastically deforming under the action of an external force and, when the external force is removed, restoring its original shape by virtue of the elastic force. Specifically, the elastic limiting portion 728 is elastically deformed during installation onto the power supply mechanism M11 so as to pass through the first limiting surface 221. When the second sealing member 720 is installed in place relative to the power supply mechanism M11, the elastic limiting portion 728 restores its original shape and causes the second limiting surface 7281 to abut against the first limiting surface 221, thereby limiting the movement of the second sealing member 720 relative to the power supply mechanism M11.

[0314] In the disclosed embodiment, the first limiting surface 221 and the second limiting surface 7281 can be perpendicular to the assembly direction of the second sealing member 720 relative to the power supply mechanism M11, or can form an acute or obtuse angle with the assembly direction. The first limiting surface 221 and the second limiting surface 7281 can be arranged parallel to each other. When the second sealing member 720 is assembled to the power supply mechanism M11, the first limiting surface 221 and the second limiting surface 7281 are in contact with each other.

[0315] In the embodiment of the present disclosure, the assembly direction of the power supply mechanism M11 and the second seal 720 can be the direction in which the power supply mechanism M11 approaches or moves away from the atomizer assembly 600; the assembly direction of the power supply mechanism M11 and the second seal 720 can also be associated with the axial direction of the seal channel 721. For example, the assembly direction of the power supply mechanism M11 and the second seal 720 is parallel to the axial direction of the seal channel 721, thereby reducing the possibility of the airflow driving the second seal 720 to disengage relative to the power supply mechanism M11 under the action of the first limiting surface 221 and the second limiting surface 7281.

[0316] According to the technical solution provided by the embodiment of the present disclosure, the power supply mechanism M11 is provided with a first limiting surface 221, and the second sealing member 720 has an elastic limiting portion 728. The second limiting surface 7281 of the elastic limiting portion 728 can abut against the second limiting surface 7281, thereby limiting the second sealing member 720 from escaping from the power supply mechanism M11, improving the connection stability between the second sealing member 720 and the power supply mechanism M11, and thereby improving the sealing effect.

[0317] In order to optimize the structure of the airflow chamber 220, referring to Figures 29, 30 and 31, in some possible embodiments of the present disclosure, the second air inlet channel 210 includes an airflow chamber 220, which is located on the side of the power supply mechanism M11 away from the atomization assembly 600, the first limiting surface 221 is the inner wall of the airflow chamber 220, and at least a portion of the elastic limiting portion 728 is accommodated in the airflow chamber 220.

[0318] In some embodiments, the second seal 720 may not be located in the airflow cavity 220, or the portion of the second seal 720 located in the airflow cavity 220 does not fit the circumferential inner wall of the airflow cavity 220. For example, a portion of the elastic limiting portion 728 of the second seal 720 is located in the airflow cavity 220 and does not fit the cavity wall of the airflow cavity 220.

[0319] In the disclosed embodiment, the first limiting surface 221 may be an inner wall of the power supply mechanism M11 that forms the airflow chamber 220. Alternatively, the power supply mechanism M11 may have a recess or protrusion formed on the inner side of the airflow chamber 220, and the first limiting surface 221 may be the surface of the recess or protrusion. For example, the first limiting surface 221 may be a surface on the side of the power supply mechanism M11 that is away from the atomizer assembly 600.

[0320] In the disclosed embodiment, the elastic limiting portion 728 can be provided through a portion of the structure of the power supply mechanism M11. For example, the elastic limiting portion 728 can be provided from the power supply mechanism M11 on the side close to the atomizing device M10200 to the airflow chamber 220. The power supply mechanism M11 is provided with a through hole corresponding to the elastic limiting portion 728. The outer wall of the elastic limiting portion 728 fits with the inner wall of the through hole to achieve a good sealing effect. The cross-section of the elastic limiting portion 728 and the through hole can be regular or irregular shapes such as circular, square, or triangular.

[0321] In the disclosed embodiment, a protrusion or a recess may be provided around the elastic limiting portion 728, and the second limiting surface 7281 is the surface of the protrusion or recess. Referring to Figures 28 and 32, in some examples, the second sealing member 720 includes a third structural portion 729 and an elastic limiting portion 728 extending from the third structural portion 729 toward the airflow chamber 220. The elastic limiting portion 728 includes a flange structure 7282. The flange structure 7282 forms a second limiting surface 7281 on one side of the third structural portion 729, that is, the third structural portion 729 and the flange structure 7282 respectively clamp and secure the power supply mechanism M11 from opposite sides.

[0322] In the disclosed embodiment, the radial dimension of the flange structure 7282 can gradually decrease as it moves away from the third structural portion 729, i.e., the axial cross-section of the flange structure 7282 is shaped like an inverted trapezoid or triangle. This facilitates elastic deformation of the flange structure 7282 during assembly with the power supply mechanism M11 and improves the load-bearing capacity of the flange structure 7282 on the side of the second limiting surface 7281.

[0323] In the disclosed embodiment, an extension structure 7283 may be provided at the end of the flange structure 7282 away from the third structural portion 729. This extension structure 7283 can occupy space in the airflow cavity 220, reducing the volume of the airflow cavity 220. Furthermore, the longer extension structure 7283 facilitates alignment between the elastic stop 728 and the corresponding through-hole. Furthermore, the end of the extension structure 7283 away from the flange structure 7282 may be a conical or hemispherical structure to guide the extension structure 7283 into the through-hole.

[0324] In the disclosed embodiment, there can be one or more elastic limiting portions 728, and the plurality of elastic limiting portions 728 can be distributed in an array, such as a rectangular array or a circular array, about the surface of the third structural portion 729. Referring to Figures 28 and 31 , there are four elastic limiting portions 728, distributed in a rectangular array.

[0325] In the embodiment of the present disclosure, the airflow chamber 220 is located on the side of the power supply mechanism M11 away from the atomization assembly 600. The airflow chamber 220 can be connected to the accommodating chamber 240 of the battery / electronic control assembly. The airflow in the airflow chamber 220 can also take away the heat generated by the battery / electronic control assembly, thereby cooling the battery / electronic control assembly.

[0326] According to the technical solution provided by the embodiment of the present disclosure, at least a portion of the elastic limiting portion 728 is accommodated in the airflow cavity 220, so that the first limiting surface 221 and the second limiting surface 7281 can be abutted, the force is more balanced, and the elastic limiting portion 728 is not easy to fall out of the power supply mechanism M11, which also helps to reduce the volume of the airflow cavity 220, thereby optimizing the distribution of the airflow.

[0327] To facilitate the assembly of the second seal 720, referring to Figures 28, 29 and 30, in some possible embodiments of the present disclosure, the power supply mechanism M11 also includes an installation groove 230, which is located on the side of the power supply mechanism M11 close to the atomization assembly 600, and at least a portion of the second seal 720 is accommodated in the installation groove 230.

[0328] In the disclosed embodiment, the mounting groove 230 can accommodate the third structural portion 729 of the second sealing member 720. In some examples, the profile of the mounting groove 230 matches the profile of the third structural portion 729. In other words, the outer wall of the third structural portion 729 fits in contact with the inner wall of the mounting groove 230. The third structural portion 729 can be convex or concave relative to the surface of the power supply mechanism M11 on the side close to the atomizer assembly 600; alternatively, the surface of the third structural portion 729 can be flush with the surface of the power supply mechanism M11 on the side close to the atomizer assembly 600.

[0329] The technical solution provided by the embodiment of the present disclosure, by providing the installation groove 230, on the one hand facilitates the assembly of the second sealing member 720 and the power supply mechanism M11 and facilitates the mutual limitation of the two. On the other hand, at least a part of the second sealing member 720 is accommodated in the installation groove 230, which also helps to reduce the space occupied and facilitates the miniaturization of the device.

[0330] In order to improve the sealing effect, referring to Figures 20, 21, 22 and 23, in some possible embodiments of the present disclosure, the second sealing member 720 includes a second structural portion 723, which extends into the first air intake channel 530 and fits against the inner wall of the circumferential side of the first air intake channel 530.

[0331] In the disclosed embodiment, the second structural portion 723 fits tightly against the inner peripheral wall of the first air inlet passage 530 , that is, the outer peripheral wall of the second structural portion 723 and the inner peripheral wall of the first air inlet passage 530 have similar structures and sizes, and can fit tightly against each other.

[0332] In the disclosed embodiment, an annular protrusion may be provided on at least one of the outer peripheral wall of the second structural portion 723 and the inner peripheral wall of the first air inlet passage 530 to further enhance the sealing effect. The annular protrusion may be one or more, with multiple annular protrusions spaced apart along the axial direction of the sealing member passage 721.

[0333] It should be noted that the second structural portion 723 extends into the first air inlet passage 530, and the opening of the sealing member passage 721 should also be provided in the second structural portion 723, so that the sealing member passage 721 communicates with the first air inlet passage 530. For example, the airflow passage extends through the first structural portion 722 and the second structural portion 723 along the axial direction of the first air inlet passage 530, and the inner contour of the airflow passage is similar to the outer contour of the second structural portion 723.

[0334] In some possible embodiments of the present disclosure, the second end surface 510 of the atomizing assembly 600 is a substantially flat surface, without a protruding structure, or with a smaller protruding structure to facilitate packaging and storage.

The atomization assembly 600 extends into the limited space 120 to be connected to the power supply mechanism M11. Optionally, the second structural portion 723 is located in the limited space 120 and is not likely to affect the overall appearance of the power supply mechanism M11.

[0338] In some possible embodiments of the present disclosure, the atomizing assembly 600 is formed with an atomizing chamber 410 for mixing the atomized atomized medium with air, a second boss 550 is arranged in the atomizing chamber 410, and the first air inlet channel 530 is opened on the second boss 550, that is, the second sealing member 720 is inserted into the second boss 550, and the second boss 550 protrudes relative to the bottom wall of the atomizing chamber 410, so that the condensate and other liquids in the atomizing chamber 410 are not easily leaked through the air inlet of the first air inlet channel 530.

[0339] The technical solution provided by the embodiment of the present disclosure extends the second structural portion 723 into the first air inlet channel 530, and makes the second structural portion 723 fit with the inner wall of the peripheral side of the first air inlet channel 530, and the two have a large contact area, thereby isolating the first air inlet channel 530 from the gap between the power supply mechanism M11 and the atomization assembly 600 to provide good sealing performance.

[0340] In order to improve the connection stability between the atomizer assembly 600 and the power supply mechanism M11, referring to Figures 17, 18 and 19, in some possible embodiments of the present disclosure, the power supply mechanism M11 forms a limiting structure 110, which is at least used to limit the radial movement of the atomizer assembly 600 relative to the power supply mechanism M11 along the sealing channel 721. The limiting structure 110 can form the above-mentioned limiting space 120.

[0341] In the disclosed embodiment, the second seal 720 can also cooperate with the limiting structure 110 to limit the power supply mechanism M11 and the atomizer assembly 600. Specifically, the first structural portion 722 cooperates with the power supply mechanism M11 to limit the movement of the second seal 720 relative to the power supply mechanism M11; the second structural portion 723 cooperates with the atomizer assembly 600 to limit the movement of the second seal 720 relative to the atomizer assembly 600. With the second seal 720 acting as an intermediate bridge, the movement of the atomizer assembly 600 relative to the power supply mechanism M11 can be limited.

[0342] In the embodiment of the present disclosure, the structure used for limiting the second seal 720 may also include other structures arranged on the second seal 720, such as a second sealing ring 727; for example, a rib or groove arranged on the surface of the second seal 720.

[0343] In the embodiment of the present disclosure, the second seal 720 can limit the radial movement of the atomizer assembly 600 relative to the power supply mechanism M11 along the seal channel 721; it can also limit the axial movement of the atomizer assembly 600 relative to the power supply mechanism M11 along the seal channel 721, for example, the first structural part 722 interference fits the airflow cavity 220; the second structural part 723 interference fits the first air inlet channel 530; or, the second seal 720 limits the relative rotation of the atomizer assembly 600 and the power supply mechanism M11 along the central axis of the seal channel 721, for example, the first structural part 722 and the second structural part 723 are both set to square structures.

[0344] In the embodiment of the present disclosure, the limiting structure 110 can be an annular limiting structure 110 provided on the power supply mechanism M11, and the annular limiting structure 110 forms a limiting space 120. The atomizing assembly 600 can extend into the limiting space 120 to achieve assembly of the two. The inner wall of the limiting structure 110 and the outer wall of the atomizing assembly 600 can also be provided with locking structures such as buckles to improve the stability of the connection. It should be noted that the limiting structure 110 can also be provided on the atomizing assembly 600 to form the limiting space 120, and the power supply mechanism M11 extends into the limiting space 120 to form a fit. In one embodiment, the limiting structure 110 is part of the first shell 100 of the power supply mechanism M11.

[0345] According to the technical solution provided by the embodiment of the present disclosure, the second seal 720 can cooperate with the limiting structure 110 of the power supply mechanism M11 to at least limit the relative movement of the atomizer assembly 600 and the power supply mechanism M11 along the radial direction of the seal channel 721, thereby improving the connection stability between the atomizer assembly 600 and the power supply mechanism M11.

[0346] In order to improve the connection stability, referring to Figures 20, 25 and 26, in some possible embodiments of the present disclosure, the power supply mechanism M11 also includes a limiting protrusion 231, which is arranged in the airflow cavity 220, and the second sealing member 720 includes an avoidance groove 724 arranged corresponding to the limiting protrusion 231, and the avoidance groove 724 is sleeved on the limiting protrusion 231.

[0347] In the disclosed embodiment, the limiting protrusion 231 of the power supply mechanism M11 can be a reinforcing structure, such as a reinforcing rib, or a connecting structure, such as a positioning post or a positioning protrusion. For example, the limiting protrusion 231 is a mounting structure for the second conductive member 820; in another example, the limiting protrusion 231 is the first boss 222 for providing the sensing channel 260. It should be noted that the avoidance groove 724 is also provided corresponding to the airflow channel to facilitate airflow.

[0348] In the embodiment of the present disclosure, the avoidance groove 724 is sleeved on the limiting protrusion 231, and the two can be set at intervals to facilitate assembly; the two can also be set in a close fit to improve the connection stability of the second seal 720, and serve as a first limiting structure to limit the movement of the atomization assembly 600 relative to the power supply mechanism M11.

[0349] In the disclosed embodiment, the avoidance groove 724 corresponds to the position of the limiting protrusion 231. The avoidance groove 724 can be provided on the peripheral outer wall of the first structural portion 722, or on the side of the first structural portion 722 away from the atomizer assembly 600. For example, the side of the first structural portion 722 away from the atomizer assembly 600 is provided with the avoidance groove 724 corresponding to the second conductive member 820, and the avoidance groove 724 corresponding to the first boss 222.

[0350] According to the technical solution provided by the embodiment of the present disclosure, the power supply mechanism M11 also includes a limiting protrusion 231 arranged on the airflow cavity 220, and the second sealing component 720 is provided with an avoidance groove 724 corresponding to the limiting protrusion 231. On the one hand, the limiting protrusion 231 can be avoided, and on the other hand, the avoidance groove 724 is sleeved on the limiting protrusion 231. The two can limit each other to improve the connection stability between the second sealing component 720 and the power supply mechanism M11.

[0351] In order to improve the connection stability, referring to Figures 28 and 30, in some possible embodiments of the present disclosure, the power supply mechanism M11 includes a mounting groove 230, at least part of the second sealing member 720 is accommodated in the mounting groove 230, the power supply mechanism M11 also includes a limiting protrusion 231 arranged on the mounting groove 230, and the second sealing member 720 is provided with an avoidance groove 724 corresponding to the limiting protrusion 231.

[0352] In the disclosed embodiment, the profiles of the mounting groove 230 and the third structural portion 729 can be regular or irregular shapes, such as circular, square, or elliptical. For example, the profile of the third structural portion 729 is approximately rectangular, with chamfered corners. The third structural portion 729 has concave arc-shaped structures at both ends along its length, thereby forming avoidance grooves 724 at both ends of the third structural portion 729 along its length. The avoidance grooves 724 are used to avoid the limiting protrusions 231 of the power supply mechanism M11.

[0353] In the embodiment of the present disclosure, the limiting protrusion 231 of the power supply mechanism M11 can be used as a limit, and the limiting protrusion 231 can also be used to enhance the structural strength, such as ribs, etc. The limiting protrusion 231 can also be formed by the power supply mechanism M11 to avoid other components. For example, an atomization component 600 is installed in the power supply mechanism M11, and the power supply mechanism M11 forms a limiting protrusion 231 to avoid the atomization component 600.

[0354] According to the technical solution provided by the embodiment of the present disclosure, the power supply mechanism M11 includes a limiting protrusion 231 arranged on the installation groove 230, and the second sealing member 720 is provided with an avoidance groove 724 corresponding to the limiting protrusion 231 of the installation groove 230. On the one hand, the limiting protrusion 231 can be avoided, and on the other hand, the avoidance groove 724 and the limiting protrusion 231 can limit each other to improve the connection stability between the second sealing member 720 and the power supply mechanism M11.

[0355] In order to improve the stability of the connection between the power supply mechanism M11 and the atomization assembly 600, referring to Figures 17 and 26, in some possible embodiments of the present disclosure, the atomization device M10 also includes a magnetic structure 840, which is arranged between the power supply mechanism M11 and the atomization assembly 600, and the second sealing member 720 cooperates with the magnetic structure 840 to relatively fix the atomization assembly 600 and the power supply mechanism M11.

[0356] In the embodiment of the present disclosure, the magnetic attraction structure 840 may include a magnetic attraction portion, which may utilize magnetism to attract a magnetic component. For example, the power supply mechanism M11 and the atomizer assembly 600 are respectively provided with a magnetic attraction portion, and the two magnetic attraction portions have opposite polarities, so that the power supply mechanism M11 and the atomizer assembly 600 can be fixed by adsorption through the magnetic attraction portion. Alternatively, one of the power supply mechanism M11 and the atomizer assembly 600 is provided with a magnetic attraction portion, and the other is provided with a magnetic component containing magnetic materials such as iron and nickel (for example, the outer shell portion of the atomizer assembly 600), and the magnetic attraction portion attracts the magnetic component, thereby magnetically fixing the power supply mechanism M11 and the atomizer assembly 600.

[0357] In the embodiment of the present disclosure, the second seal 720 can be used in conjunction with the magnetic structure 840 to limit the position, that is, the magnetic structure 840 limits the axial movement of the atomizer assembly 600 relative to the power supply mechanism M11 along the seal channel 721, and the second seal 720 limits the radial movement of the atomizer assembly 600 relative to the power supply mechanism M11 along the seal channel 721 through the first structural part 722 and the second structural part 723 to limit the shaking of the atomizer assembly 600 relative to the power supply mechanism M11.

[0358] In the embodiment of the present disclosure, the magnetic structure 840, the limiting structure 153 and the second seal 720 can also be combined to work together to limit the atomization assembly 600 relative to the power supply mechanism M11, reduce shaking, and improve connection stability.

[0359] The technical solution provided by the embodiment of the present disclosure provides an effective limit for the atomizer assembly 600 and the power supply mechanism M11 by setting a magnetic structure 840. The second seal 720 and the magnetic structure 840 are combined to improve the connection stability of the atomizer assembly 600 and the power supply mechanism M11.

[0360] In order to facilitate the assembly of the second sealing member 720 and improve the connection stability, referring to Figures 20, 22, and 24, in some possible embodiments of the present disclosure, the power supply mechanism M11 also includes a second conductive member 820, and the second sealing member 720 is provided with a through hole 725, and the second conductive member 820 passes through the through hole 725 to connect to the atomization assembly 600.

[0361] In the embodiment of the present disclosure, the second conductive member 820 can be an elastic electric needle for the power supply mechanism M11 to supply power to the atomizer assembly 600. The peripheral outer wall of the second conductive member 820 and the peripheral inner wall of the through hole 725 can be spaced apart for easy assembly; they can also be fitted together to improve the connection stability of the second sealing member 720, and serve as a first limiting structure to limit the movement of the atomizer assembly 600 relative to the power supply mechanism M11.

[0362] In the embodiment of the present disclosure, a plurality of second conductive members 820 may be provided, and the second seal 720 is provided with a via 725 corresponding to each conductive member. The plurality of vias 725 may be evenly distributed. For example, the second seal 720 is provided with two vias 725, and the two vias 725 are symmetrically distributed on both sides of the seal channel 721 along the length direction of the first structural portion 722.

[0363] The technical solution provided by the embodiment of the present disclosure is that the second sealing member 720 is provided with a via 725, which can facilitate the second conductive member 820 to pass through the via 725 to connect to the atomizer assembly 600. In addition, the second conductive member 820 can serve as a positioning or guiding member to facilitate the assembly of the second sealing member 720 and the power supply mechanism M11. The second conductive member 820 and the via 725 can cooperate with each other to form a limit, thereby improving the connection stability between the second sealing member 720 and the power supply mechanism M11.

[0364] In order to improve the sealing performance, referring to Figures 22 and 24, in some possible embodiments of the present disclosure, the second sealing member 720 also includes a first sealing ring 726, which surrounds the through hole 725 and abuts against the atomization assembly 600, for example, the first sealing ring 726 abuts against the second end face 510.

[0365] In the embodiment of the present disclosure, the via hole 725 can be provided in the first structural portion 722, and the first sealing ring 726 also corresponds to a protruding portion of the first structural portion 722 toward the second end surface 510. The contour of the first sealing ring 726 can be the same as or different from the contour of the via hole 725. For example, the contour of the first sealing ring 726 and the radial contour of the via hole 725 are both circular.

[0366] In the disclosed embodiment, the first sealing ring 726 can be made of an elastic material similar to the second sealing ring 727. When the atomizer assembly 600 is assembled to the power supply mechanism M11, the first sealing ring 726 elastically deforms to closely fit the second end surface 510. In addition, each via 725 can correspond to multiple first sealing rings 726, and the multiple first sealing rings 726 have different sizes, forming a nested structure to further improve the sealing performance.

[0367] It can be understood that the close combination of the first sealing ring 726 and the atomization assembly 600 can, on the one hand, provide a good airtight seal for stable airflow; on the other hand, it can also provide dustproof, leakproof, soundproof and other functions, for example, preventing the atomized medium of the atomization assembly 600 from flowing into the power supply mechanism M11 through the hole 725, thereby protecting the power supply assembly, control assembly, etc. in the power supply mechanism M11.

[0368] According to the technical solution provided by the embodiment of the present disclosure, the second sealing member 720 is provided with a first sealing ring 726. The first sealing ring 726 surrounds the circumference of the through hole 725 and abuts against the atomizer assembly 600, thereby isolating the through hole 725 from the gap between the power supply mechanism M11 and the atomizer assembly 600 to improve the sealing performance.

[0369] In order to improve the sealing performance, referring to Figure 28, in some possible embodiments of the present disclosure, the second sealing member 720 also includes a first sealing ring 726, which abuts against the atomization assembly 600, and the through hole 725 and the sealing member channel 721 are both located on the inner side of the first sealing ring 726.

[0370] In the embodiment of the present disclosure, the first sealing ring 726 is an annular structure surrounding the through hole 725 and the sealing member channel 721. The first sealing ring 726 may be a regular or irregular shape such as a circle, a square, or an ellipse.

[0371] The technical solution provided by the embodiment of the present disclosure is to set a first sealing ring 726, and the via 725 and the sealing channel 721 are all set on the inner side of the first sealing ring 726. The isolation of multiple holes or channels is achieved by a single first sealing ring 726, which has a simple structure and is easy to implement.

[0372] In order to facilitate triggering the airflow sensor 830, referring to Figure 21, in some possible embodiments of the present disclosure, the power supply mechanism M11 is further provided with a sensing channel 260, which is connected to the airflow cavity 220, and the sensing channel 260 is connected to the airflow sensor 830; a first boss 222 is provided in the airflow cavity 220, and the first boss 222 protrudes relative to the bottom wall of the airflow cavity 220, and the opening of the sensing channel 260 is provided on the first boss 222.

[0373] In the disclosed embodiment, the sensing channel 260 is connected to the airflow cavity 220. The opening of the sensing channel 260 can be disposed on the inner wall of the airflow cavity 220 or on the first boss 222. The opening of the sensing channel 260 can be disposed in the middle or at the edge of the airflow cavity 220. For example, the opening of the sensing channel 260 is disposed on a side of the first boss 222 close to the third end surface 250. In other words, the opening of the sensing channel 260 is located on the top surface of the first boss 222 relative to the airflow cavity 220.

[0374] In the embodiment of the present disclosure, the airflow sensor 830 can serve as a starting sensor for the atomization device M10, that is, the airflow sensor 830 is used to detect the air pressure in the airflow chamber 220. When the negative pressure in the airflow chamber 220 reaches a preset pressure, the airflow sensor 830 is triggered, and the controller controls the power supply component to provide electrical energy to the atomization component 600 based on the triggering of the airflow sensor 830.

[0375] The technical solution provided by the embodiment of the present disclosure is to set the opening of the sensing channel 260 on the first boss 222 by setting the first boss 222, so that the opening of the sensing channel 260 is higher than the bottom wall of the airflow chamber 220. On the one hand, the opening of the sensing channel 260 is closer to the entrance of the first air inlet channel 530, so that the sensing of the airflow sensor 830 is more sensitive. On the other hand, it can prevent the accumulated liquid (such as tobacco oil, etc.) in the airflow chamber 220 from flowing into the sensing channel 260, so as to protect the airflow sensor 830.

[0376] In order to improve the sensing sensitivity, referring to Figure 33, in some possible embodiments of the present disclosure, the second air inlet channel 210 includes an airflow chamber 220, and the power supply mechanism M11 is formed with a accommodating chamber 240, which is used to accommodate batteries and / or electronic control components, and the accommodating chamber 240 is connected to the airflow chamber 220; the power supply mechanism M11 is also provided with a sensing channel 260, which is connected to the airflow sensor 830, and the sensing channel 260 is connected to the accommodating chamber 240.

[0377] In the embodiment of the present disclosure, the accommodating chamber 240 can be set in the part of the power supply mechanism M11 away from the atomizer assembly 600. The accommodating chamber 240 can be formed by the bracket 200, or the accommodating chamber 240 is enclosed by the bracket 200 and the first shell 100.

[0378] In some examples, the accommodating chamber 240 is located between the airflow chamber 220 and the sensing channel 260. For example, the airflow chamber 220 is set at one end of the accommodating chamber 240 close to the atomizing assembly 600, and the sensing channel 260 is set at the end of the accommodating chamber 240 away from the atomizing assembly 600.

[0379] According to the technical solution provided by the embodiment of the present disclosure, the airflow chamber 220 and the sensing channel 260 are connected through the accommodating chamber 240. The airflow in the airflow chamber 220 drives the airflow in the accommodating chamber 240, thereby forming an airflow that can cool the battery and / or electronic control components in the accommodating chamber 240.

[0380] In order to improve the sealing performance, referring to Figures 17, 18, 19, 26 and 27, in some possible embodiments of the present disclosure, the power supply mechanism M11 includes a first shell 100 and a bracket 200, the bracket 200 is accommodated in the first shell 100, the second air inlet channel 210 includes a channel section 213 formed by the first shell 100 and the bracket 200, the atomization device M10 also includes a third seal 730, the third seal 730 is sealed between the bracket 200 and the first shell 100, and the third seal 730 is located on the side of the channel section 213 close to the atomization assembly 600.

[0381] In the disclosed embodiment, the first housing 100 of the power supply mechanism M11 is used to accommodate the bracket 200, the second seal 720, the power supply components, the electronic control components, etc. to provide protection. The first housing 100 may include a first outer peripheral surface 130, a second outer peripheral surface 140, a limiting structure 110, etc.

[0382] In the disclosed embodiment, the bracket 200 may be a battery bracket 200 of a power supply assembly, a circuit board bracket 200 of an electronic control assembly, etc. The bracket 200 may include a limiting protrusion 231, a sensing channel 260, etc. The airflow cavity 220 may be formed in the bracket 200, and the third channel opening 211 extends through the bracket 200 and communicates with the airflow cavity 220. The third end surface 250 may also be the side of the bracket 200 facing the atomizer assembly 600.

[0383] In the embodiment of the present disclosure, the channel section 213 may include a groove opened on the outer wall of the bracket 200, and the groove and the inner wall of the first shell 100 are enclosed to form the channel section 213. Since there may be a gap between the outer wall of the bracket 200 and the inner wall of the first shell 100, air leakage may occur. The provision of a third seal 730 can alleviate this problem.

[0384] In the disclosed embodiment, the third seal 730 can be an annular structure surrounding the bracket 200. A receiving groove is defined on the peripheral outer wall of the bracket 200. The third seal 730 is disposed within the receiving groove and abuts against the inner wall of the receiving groove. The receiving groove can limit the third seal 730. The other side of the third seal 730 abuts against the peripheral inner wall of the first shell 100. An elastic annular protrusion can also be provided between the third seal 730 and the first shell 100 to further enhance the sealing effect. There can be one or more annular protrusions, with multiple annular protrusions spaced apart along the axial direction of the power supply mechanism M11.

[0385] It should be noted that the third sealing member 730 and the second sealing member 720 can also be used as an integrated structure and sleeved on the end of the bracket 200 to provide a more comprehensive sealing effect.

[0386] The technical solution provided by the embodiment of the present disclosure is to set a third seal 730 between the first shell 100 and the bracket 200. The third seal 730 is located on the side of the channel section 213 close to the atomizer assembly 600, thereby isolating the channel section 213 from the gap between the power supply mechanism M11 and the atomizer assembly 600, providing good sealing performance.

[0387] In order to improve the sealing performance, referring to Figure 33, in some possible embodiments of the present disclosure, the atomization device M10 also includes a fourth seal 740, which is sealed between the bracket 200 and the first shell 100, and the fourth seal 740 is located on the side of the channel section 213 away from the atomization assembly 600.

The fourth seal 740 is arranged in the receiving groove and fits the inner wall of the receiving groove. The receiving groove can limit the fourth seal 740; the other side of the fourth seal 740 fits the inner wall of the circumferential side of the first shell 100.

[0389] In the embodiment of the present disclosure, an elastic annular protrusion may be provided between the fourth sealing member 740 and the first housing 100 to further enhance the sealing effect. There may be one or more annular protrusions, which may be provided at intervals along the axial direction of the power supply mechanism M11.

[0390] The technical solution provided by the embodiment of the present disclosure is to provide a fourth seal 740 between the first shell 100 and the bracket 200. The fourth seal 740 is located on the side of the channel section 213 away from the atomizer assembly 600, thereby isolating the channel section 213 from other gaps between the bracket 200 and the first shell 100, providing good sealing performance.

[0391] In order to improve the user experience, referring to Figures 26 and 27, in some possible embodiments of the present disclosure, the channel section 213 surrounds the bracket 200 along the circumference of the bracket 200, and the channel section 213 includes a third channel opening 211 opened in the bracket 200, and a fourth channel opening 212 opened in the first shell 100. The third channel opening 211 and the fourth channel opening 212 are arranged at intervals along the circumference of the bracket 200.

[0392] In the embodiment of the present disclosure, the channel section 213 can serve as the air inlet channel of the atomization device M10. When the user acts on the first air inlet channel 530, the external air flow can flow in from the fourth channel opening 212 of the channel section 213, and flow into the air flow chamber 220 through the third channel opening 211, and then flow to the first air inlet channel 530 through the sealing channel 721, thereby forming a negative pressure in the air flow chamber 220.

[0393] The technical solution provided by the embodiment of the present disclosure is that the channel section 213 surrounds the circumference of the bracket 200. On the one hand, it is convenient for processing the channel section 213. On the other hand, since the third channel opening 211 and the fourth channel opening 212 are spaced apart along the circumference of the bracket 200, there is a long distance between the two, which can reduce the outflow of condensation liquid and the like in the channel section 213 (that is, prevent the condensation liquid from flowing out of the fourth channel opening 212 to the outside of the first shell 100), thereby improving the user experience.

[0394] In addition, the channel section 213 is provided on the peripheral side of the bracket 200, which can also prevent airflow from passing through the power supply components (such as batteries, etc.), thereby protecting the power supply components and improving safety. It should be noted that the fourth channel opening 212 can be provided on the peripheral side surface of the first shell 100, or on the bottom side surface of the first shell 100 (the side surface away from the atomizer assembly 600).

[0395] In order to facilitate the control of airflow, referring to Figures 26 and 27, in some possible embodiments of the present disclosure, the third channel opening 211 of the channel section 213 is arranged on the inner wall of the airflow cavity 220; the power supply mechanism M11 includes a first outer peripheral surface 130 and a second outer peripheral surface 140, the size of the first outer peripheral surface 130 is smaller than the size of the second outer peripheral surface 140, and the fourth channel opening 212 of the channel section 213 is arranged on the first outer peripheral surface 130.

[0396] In the disclosed embodiment, the first outer peripheral surface 130 and the second outer peripheral surface 140 are the peripheral surfaces of the power supply mechanism M11, which can be used for a user to grip. For example, the power supply mechanism M11 includes two opposing first outer peripheral surfaces 130 and two opposing second outer peripheral surfaces 140, which together form the peripheral outer wall of the power supply mechanism M11.

[0397] In the embodiment of the present disclosure, the size of the first outer peripheral surface 130 is smaller than the size of the second outer peripheral surface 140, specifically, the area of ​​the first outer peripheral surface 130 is smaller than the area of ​​the second outer peripheral surface 140. It can be understood that when the first outer peripheral surface 130 and the second outer peripheral surface 140 have similar axial lengths along the power supply mechanism M11, the size of the first outer peripheral surface 130 along the circumferential direction of the power supply mechanism M11 is smaller than the size of the second outer peripheral surface 140 along the circumferential direction of the power supply mechanism M11, that is, the first outer peripheral surface 130 is the narrow side surface of the power supply mechanism M11, and the second outer peripheral surface 140 is the wide side surface of the power supply mechanism M11.

[0398] In the embodiment of the present disclosure, the channel section 213 can be arranged on one side of the bracket 200, or it can be an annular structure surrounding the bracket 200. One or more third channel openings 211 can be set along the channel section 213, and one or more fourth channel openings 212 can also be set. Multiple fourth channel openings 212 can reduce the possibility of blockage by user grip, and multiple third channel openings 211 facilitate stable distribution of airflow. In addition, the third channel openings 211 also have a saving effect.

[0399] The technical solution provided by the disclosed embodiment comprises a second air inlet channel 210 provided in the power supply mechanism M11, which communicates with the outside world. Due to the provision of the second seal 720, the gap between the third end surface 250 and the second end surface 510 is blocked, forcing airflow to flow through the second air inlet channel 210 to the first air inlet channel 530. The second air inlet channel 210 can be designed as required to facilitate airflow control and provide stable air pressure. Furthermore, the fourth channel opening 212 is located on the third end surface, enhancing the structural aesthetics while also preventing it from being blocked by the user's grip.

[0400] In order to improve the sealing performance, referring to Figures 28, 29 and 31, in some possible embodiments of the present disclosure, the second air inlet channel 210 includes an airflow cavity 220 and a fourth channel opening 212, the fourth channel opening 212 is arranged on the first shell 100, at least one side of the airflow cavity 220 passes through the bracket 200 and extends to the first shell 100, and the fourth channel opening 212 is connected to the airflow cavity 220 through at least one channel section 213.

[0401] In the embodiment of the present disclosure, at least one side of the airflow cavity 220 passes through the bracket 200. In other words, a channel is provided on the corresponding side of the bracket 200 corresponding to the airflow cavity 220, or no physical structure is provided on the corresponding side of the bracket 200 corresponding to the airflow cavity 220, and the corresponding side wall of the airflow cavity 220 is defined by the inner wall of the first shell 100.

[0402] In the embodiment of the present disclosure, the airflow cavity 220 may penetrate the bracket 200 on one or more sides. For example, both sides of the airflow cavity 220 parallel to its length direction penetrate the bracket 200, and the protrusions 156 and the fourth channel opening 212 are provided on both sides of the airflow cavity 220 parallel to its width direction.

[0403] In the embodiment of the present disclosure, the fourth channel opening 212 can be connected to the airflow cavity 220 through one or more channel sections 213. For example, each fourth channel opening 212 is connected to two channel sections 213, and the two channel sections 213 are respectively connected to the two ends of the corresponding through hole 1521.

[0404] According to the technical solution provided by the embodiment of the present disclosure, the airflow cavity 220 passes through the bracket 200, so that the airflow cavity 220 is connected to the fourth channel opening 212, and the fourth channel opening 212 can be connected to the airflow cavity 220 through one or more channel sections 213, so that the airflow flows between the fourth channel opening 212 and the airflow cavity 220.

[0405] 17 , 20 , 21 , 22 , 23 , 26 and 27 , in a possible embodiment of the present disclosure, the atomization device M10 includes a power supply mechanism M11 and an atomization assembly 600. The power supply mechanism M11 includes a first shell 100 and a bracket 200. The bracket 200 is housed in the first shell 100 and is used to support batteries, electronic control components, etc. The bracket 200 includes a third end face 250. The first shell 100 extends beyond the third end face 250 to form a limiting structure 110. The atomization assembly 600 can be inserted into the limiting structure 110 to be connected to the power supply mechanism M11, and the second end face 510 of the atomization assembly 600 is opposite to the third end face 250.

[0406] Among them, the second air inlet channel 210 includes an airflow cavity 220 opened on the third end surface 250, the airflow cavity 220 is connected to the airflow sensor 830 through the sensing channel 260, the airflow cavity 220 is used as a negative pressure sensing cavity, and a first air inlet channel 530 is opened on the atomization assembly 600. The second air inlet channel 210 also includes a channel section 213 formed between the first shell 100 and the bracket 200. The channel section 213 is connected to the airflow cavity 220, and the airflow cavity 220 is connected to the first air inlet channel 530.

[0407] On this basis, the atomizing device M10 is further provided with a second sealing member 720 and a third sealing member 730. The third sealing member 730 is provided between the bracket 200 and the first shell 100 and is located on the side of the channel section 213 close to the atomizing assembly 600 to isolate the gap between the second air inlet channel 210 relative to the third end face 250 and the second end face 510. The second sealing member 720 is provided between the atomizing assembly 600 and the bracket 200 and is used to connect the first air inlet channel 530 and the airflow chamber 220 through the sealing member channel 721, and to isolate the gap between the first air inlet channel 530 and the airflow chamber 220 relative to the third end face 250 and the second end face 510.

[0408] Specifically, the second sealing member 720 includes a first structural portion 722 and a second structural portion 723. The first structural portion 722 extends into the airflow chamber 220 and seals with the airflow chamber 220; the second structural portion 723 extends into the first air inlet channel 530 and seals with the first air inlet channel 530. The first structural portion 722 is provided with a through hole 725 and an avoidance groove 724 to facilitate the second conductive member 820 of the power supply mechanism M11 to pass through the second sealing member 720 and connect to the atomizer assembly 600. The second sealing member 720 also includes a second sealing ring 727 provided on the outer wall of the first structural portion 722, and a first sealing ring 726 provided around the through hole 725 to further enhance the sealing effect.

[0409] Referring to Figures 17, 28, 29, 30, 31, 32 and 33, in another possible embodiment of the present disclosure, the atomization device M10 includes a power supply mechanism M11 and an atomization assembly 600, the power supply mechanism M11 includes a first shell 100 and a bracket 200, the bracket 200 is accommodated in the first shell 100, and is used to support batteries, electronic control components, etc., the bracket 200 includes a third end face 250, the first shell 100 extends beyond the third end face 250 to form a limiting structure 110, the atomization assembly 600 can be inserted into the limiting structure 110 to connect to the power supply mechanism M11, and the second end face 510 of the atomization assembly 600 is opposite to the third end face 250.

[0410] The second air inlet channel 210 includes an airflow chamber 220, which is disposed on the side of the bracket 200 facing away from the third end surface 250. The bracket 200 and the first shell 100 further enclose a housing 240, in which the battery / electronic control assembly is disposed. A sensing channel 260 is disposed at one end of the housing 240 away from the airflow chamber 220, and is connected to the airflow sensor 830 through the sensing channel 260. The airflow chamber 220 serves as a negative pressure sensing chamber. The second air inlet channel 210 also includes a fourth channel opening 212, each of which is connected to the airflow chamber 220 via two channel sections 213. A first air inlet channel 530 is provided on the atomizer assembly 600, and the airflow chamber 220 is connected to the first air inlet channel 530 via a second sealing member 720.

[0411] On this basis, the atomizing device M10 is further provided with a second seal 720, a third seal 730, and a fourth seal 740. The third seal 730 and the fourth seal 740 are provided between the bracket 200 and the first shell 100, and are respectively located on both sides of the second air inlet channel 210 to isolate the gap between the second air inlet channel 210 relative to the third end face 250 and the second end face 510, and the gap between the second air inlet channel 210 relative to the bracket 200 and the first shell 100. The second seal 720 is provided between the atomizing assembly 600 and the bracket 200, and is used to connect the first air inlet channel 530 and the airflow chamber 220 through the seal channel 721, and to isolate the gap between the first air inlet channel 530 and the airflow chamber 220 relative to the third end face 250 and the second end face 510.

[0412] Specifically, the second sealing member 720 includes a third structural portion 729 and a second structural portion 723. The third structural portion 729 is located in the mounting groove 230 and is sealed with the mounting groove 230. The second structural portion 723 extends into the first air inlet channel 530 and is sealed with the first air inlet channel 530. A through hole 725 and an avoidance groove 724 are provided on the third structural portion 729 to facilitate the second conductive member 820 of the power supply mechanism M11 to pass through the second sealing member 720 and be connected to the atomization assembly 600. A first sealing ring 726 is provided on the side of the third structural portion 729 close to the atomization assembly 600. The first sealing ring 726 surrounds the through hole and the sealing member channel 721.

[0413] Among them, the third structural part 729 of the second sealing member 720 is connected to the mounting groove 230 of the power supply mechanism M11, and four elastic limiting parts 728 are provided on the side of the third structural part 729 away from the atomization assembly 600. The elastic limiting part 728 passes through the bracket 200 and extends to the airflow chamber 220. The elastic limiting part 728 includes a second limiting surface 7281. The side of the bracket 200 away from the third end face 250 forms a first limiting surface 221. The first limiting surface 221 abuts against the second limiting surface 7281. The second limiting surface 7281 is formed by a flange structure 7282. The radial dimension of the flange structure 7282 gradually decreases in the direction away from the third structural part 729, and an extension structure 7283 is also provided at the end of the flange structure 7282 away from the third structural part 729. The end of the extension structure 7283 is hemispherical.

[0414] During use of the atomizing device M10, the user applies negative pressure to the first air inlet channel 530, causing airflow to flow from the channel section 213 into the airflow chamber 220 to act on the airflow sensor 830, and then flow into the first air inlet channel 530 to merge with the atomizing medium to form an aerosol for the user. Due to the provision of the second sealing member 720, the flow path of the airflow is isolated from the gap between the third end face 250 and the second end face 510, and the overall airflow is controlled, which not only facilitates the formation of a stable and uniform negative pressure, facilitating the activation of the atomizing device M10, but also reduces noise, provides a stable limit, and prevents the atomizing medium from entering the power supply mechanism M11.

[0415] The atomizing device M10 is used to generate aerosol for the user to inhale. The atomizing device M10 is provided with an atomizing mechanism and a power supply mechanism, and the two are connected by electrical connectors such as electrical wires. The power supply mechanism can supply power to the atomizing assembly 600 in the atomizing mechanism, so that the atomizing assembly 600 can atomize the aerosol-generating matrix to form an aerosol. In related technologies, the atomizing device M10 is additionally provided with connecting structural components such as magnetic components, so that the relative position between the atomizing mechanism and the power supply mechanism is kept stable through interaction forces such as magnetic attraction, thereby keeping the electrical connection between the two stable and enabling the atomizing device M10 to operate stably.

[0416] However, the electrical connectors and connecting structural components mentioned above will occupy space in the atomizing device M10, increase the number of components, and are not conducive to improving the space utilization of the atomizing device M10 and reducing the production cost.

[0417] An embodiment of the present disclosure provides an atomizing device M10 for generating aerosol for inhalation by a user. Referring to Figures 34 to 38 , the atomizing device M10 includes an atomizing mechanism M12 and a power supply mechanism M11.

[0418] The atomizing mechanism M12 is provided with an atomizing assembly 600, which can be in contact with the aerosol-generating matrix and atomize the aerosol-generating matrix into an aerosol by heating or other means for the user to inhale.

[0419] The aerosol generating substrate may be stored in the atomizing mechanism M12 or in other components of the atomizing device M10.

[0420] It should be noted that the structure and principles of the atomization assembly 600 contacting the aerosol-generating substrate and atomizing it have been applied in related technologies and will not be elaborated here.

[0421] The atomization mechanism M12 is provided with a first conductive member 810, which is used to contact the atomization assembly 600 and supply power to the atomization assembly 600 so that the atomization assembly 600 can use the electrical energy to atomize the aerosol-generating matrix to form an aerosol.

[0422] It is understood that at least a portion of the first conductive member 810 is made of a conductive material, of any type, such as copper.

[0423] The power supply mechanism M11 is used to provide electrical energy to other electrical components in the atomization device M10.

[0424] The power supply mechanism M11 includes a bracket 200 , a second conductive member 820 and a power supply assembly 300 .

[0425] The power supply assembly 300 is used as a power source for the atomization device M10.

[0426] The specific type of the power supply component 300 is not limited, such as a lithium battery. The bracket 200 is provided with a communication hole 281, and the second conductive member 820 is passed through the communication hole 281 and is electrically connected to the power supply component 300;

[0427] Alternatively, the bracket 200 includes a housing 240, and the power supply assembly 300 is disposed in the housing 240. The housing 240 provides a mounting location for the power supply assembly 300 and provides some protection. The connecting hole 281 extends along the second direction Y, and the second conductive member 820 is disposed in the connecting hole 281 and is electrically connected to the power supply assembly 300.

[0428] The specific form of electrical connection between the second conductive member 820 and the power supply component 300 is not limited. The second conductive member 820 may be in direct contact with the positive and negative poles of the power supply component 300; or the second conductive member 820 may be connected to the control circuit board and electrically conductive, and the control circuit board may be connected to the positive and negative poles of the power supply component 300 and electrically conductive, so as to regulate the voltage and current output by the power supply component 300 to the second conductive member 820 through the control circuit board.

[0429] It is understood that at least a portion of the second conductive member 820 is made of a conductive material, of any type, such as copper.

[0430] The first conductive member 810 is inserted into the communicating hole 281 so that at least a portion of the second conductive member 820 is sandwiched between the inner wall of the communicating hole 281 and the first conductive member 810 , and the second conductive member 820 is electrically connected to the first conductive member 810 .

[0431] That is to say, after the first conductive member 810 is inserted into the connecting hole 281, at least part of the second conductive member 820 is located between the inner wall of the connecting hole 281 and the first conductive member 810 and fits with both, so that the second conductive member 820 is subjected to the extrusion force from the inner wall of the connecting hole 281 and the first conductive member 810. On the one hand, the friction between the first conductive member 810 and the second conductive member 820 and between the second conductive member 820 and the inner wall of the connecting hole 281 is increased; on the other hand, the relative movement between the first conductive member 810 and the second conductive member 820 is restricted.

[0432] When at least part of the second conductive member 820 is clamped between the inner wall of the connecting hole 281 and the first conductive member 810, the relative positions of the atomization mechanism M12 and the power supply mechanism M11 also remain stable, and a conductive loop is formed between the power supply assembly 300, the second conductive member 820 and the first conductive member 810, so that the power supply mechanism M11 can supply power to the atomization mechanism M12.

[0433] The embodiment of the present disclosure inserts the first conductive member 810 into the connecting hole 281 and abuts it against the second conductive member 820 located in the connecting hole 281. While achieving electrical connection between the first conductive member 810 and the second conductive member 820 to provide electrical energy from the power supply mechanism M11 to the atomization mechanism M12, the friction between the first conductive member 810 and the second conductive member 820 and between the second conductive member 820 and the inner wall of the connecting hole 281 is increased, thereby suppressing the tendency of relative movement between the three along the second direction Y, thereby facilitating the relative position between the first conductive member 810 and the second conductive member 820 to remain stable, and facilitating the stability of the electrical connection between the two. There is no need to set up additional connecting structural members to maintain the relative position between the first conductive member 810 and the second conductive member 820, nor is there any need to set up additional electrical connectors to achieve electrical connection between the atomization mechanism M12 and the power supply mechanism M11, which is beneficial to reducing the number of components in the atomization device M10, reducing assembly steps, and reducing production costs.

[0434] It can be understood that in the scheme of setting a limited space 120, the first conductive member 810 and / or the second conductive member 820 can serve as limiting components and cooperate with the limiting space 120. The connection between the atomization mechanism M12 and the power supply mechanism M11 is realized not only through the limiting structure 110 and the limiting space 120, but also through the first conductive member 810 and the second conductive member 820. The two schemes work together to improve the connection stability between the power supply mechanism M11 and the atomization mechanism M12.

[0435] In the embodiment of the present disclosure, the base 500 of the atomization mechanism M12 can be provided with a conductive member through-hole, and the first conductive member 810 is passed through the conductive member through-hole; the bracket 200 of the power supply mechanism M11 can be provided with a connecting hole 281, and the second conductive member 820 is passed through the connecting hole 281.

[0436] In some examples, the first conductive member 810 does not extend out of the conductive member via hole. When the atomizer mechanism M12 is connected to the power supply mechanism M11, the second conductive member 820 extends into the conductive member via hole and cooperates with the conductive member via hole. Effective restraints are provided between the first conductive member 810 and the inner wall of the conductive member via hole, and between the atomizer mechanism M12 and the limiting structure 110. This can limit the radial shaking of the atomizer mechanism M12 and the power supply mechanism M11 along the second conductive member 820, and improve the insertion and removal damping of the atomizer mechanism M12 relative to the limiting structure 110.

[0437] In other examples, the second conductive member 820 does not extend out of the connecting hole 281. When the atomizer mechanism M12 is connected to the power supply mechanism M11, the first conductive member 810 extends into the connecting hole 281 and cooperates with the connecting hole 281. Effective restraints are provided between the first conductive member 810 and the inner wall of the connecting hole 281, as well as between the atomizer mechanism M12 and the limiting structure 110. This can limit the radial shaking of the atomizer mechanism M12 and the power supply mechanism M11 along the first conductive member 810, and improve the insertion and removal damping of the atomizer mechanism M12 relative to the limiting structure 110.

[0438] In some embodiments of the present disclosure, one of the first conductive member 810 and the second conductive member 820 is provided with a conductive space, and the end of the other can be inserted into the conductive space. The conductive space can be a hole, a groove, a notch, a space enclosed by multiple columnar structures, etc.

[0439] In some examples, the first conductive member 810 is provided with a conductive space, and when the atomizer mechanism M12 is connected to the power supply mechanism M11, the second conductive member 820 extends into the conductive space of the first conductive member 810. Effective restraint is provided between the first conductive member 810 and the second conductive member 820, as well as between the atomizer mechanism M12 and the retaining structure 110, thereby stabilizing the connection between the atomizer mechanism M12 and the power supply mechanism M11.

[0440] On this basis, the first conductive part 810 can also extend into the connecting hole 281, and the first conductive part 810 and the inner wall of the connecting hole 281 can be matched or spaced apart. When the first conductive part 810 and the inner wall of the connecting hole 281 are matched, multiple limits are formed between the first conductive part 810 and the second conductive part 820, between the first conductive part 810 and the inner wall of the connecting hole 281, and between the atomization mechanism M12 and the limiting structure 110, further stabilizing the connection between the atomization mechanism M12 and the power supply mechanism M11.

[0441] In other examples, the second conductive member 820 is provided with a conductive space. When the atomizer mechanism M12 is connected to the power supply mechanism M11, the first conductive member 810 extends into the conductive space of the second conductive member 820. Effective restraint is provided between the first conductive member 810 and the second conductive member 820, as well as between the atomizer mechanism M12 and the retaining structure 110, thereby stabilizing the connection between the atomizer mechanism M12 and the power supply mechanism M11.

[0442] On this basis, the second conductive part 820 can also extend into the conductive part via, and the second conductive part 820 and the inner wall of the conductive part via can be matched or spaced apart. When the second conductive part 820 and the inner wall of the conductive part via are matched, multiple limits are formed between the first conductive part 810 and the second conductive part 820, between the second conductive part 820 and the inner wall of the conductive part via, and between the atomization mechanism M12 and the limiting structure 110, further stabilizing the connection between the atomization mechanism M12 and the power supply mechanism M11.

[0443] It should be noted that the first conductive member 810 and / or the second conductive member 820 can also serve as a guiding structure to guide the atomizing mechanism M12 into the limiting space 120, thereby facilitating the assembly of the atomizing mechanism M12 and the power supply mechanism M11.

[0444] It is understood that in the solution where the second sealing member 720 is provided, the first conductive member 810 and / or the second conductive member 820 can constrain the second sealing member 720 to improve the stability of the second sealing member 720 relative to the atomization mechanism M12 and the power supply mechanism M11. For example, the first conductive member 810 is provided through the second sealing member 720, and / or the second conductive member 820 is provided through the second sealing member 720.

[0445] It should be noted that in the solution where the second sealing member 720 cooperates with the bracket 200 and the base 500 respectively, the first conductive member 810, the second conductive member 820, the second sealing member 720, the limiting structure 110 and other components can work together to provide multiple limits, greatly improving the connection stability of the atomization mechanism M12 and the power supply mechanism M11.

[0446] It can be understood that after the first conductive member 810 is inserted into the connecting hole 281, it can be pulled out again to achieve the purpose of replacing the atomization mechanism M12, and is thus suitable for a detachable atomization device M10, so that operations such as replacement of the power supply component 300 and replenishment of the aerosol generating matrix can be achieved in a detachable manner, thereby realizing the recycling of various components in the atomization device M10; it can also no longer be pulled out, and is thus suitable for a disposable atomization device M10, which is beneficial to reducing the expected service life requirements of the components in the atomization device M10 and reducing the number of components, thereby reducing the cost of the atomization device M10.

[0447] It can be understood that there is a gap fit between the outer side surface of the first conductive member 810 perpendicular to the second direction Y and the inner wall of the connecting hole 281, so that the second conductive member 820 can enter the gap between the two, thereby achieving the purpose of at least part of the second conductive member 820 being clamped between the inner wall of the connecting hole 281 and the first conductive member 810 perpendicular to the second direction Y, and reducing the probability of pushing the second conductive member 820 along the second direction Y during the process of inserting the first conductive member 810 into the connecting hole 281 and failing to clamp the second conductive member 820 between the first conductive member 810 and the inner wall of the connecting hole 281.

[0448] The specific number of the first conductive member 810 , the second conductive member 820 and the communication hole 281 is not limited, and can be one or more.

[0449] For example, referring to Figures 35 to 38, the number of the first conductive member 810, the connecting hole 281 and the second conductive member 820 are two, and the three are configured in a one-to-one correspondence. One first conductive member 810 and one second conductive member 820 are both electrically connected to the positive pole of the power supply component 300, and another first conductive member 810 and another second conductive member 820 are both electrically connected to the negative pole of the power supply component 300 to form a conductive loop.

[0450] The first conductive member 810 can completely pass through the connecting hole 281, that is, one end of the first conductive member 810 close to the power supply mechanism M11 along the second direction Y passes through the connecting hole 281 and is away from the opening of the atomization mechanism M12 along the second direction Y; or one end of the first conductive member 810 close to the power supply mechanism M11 along the second direction Y is located in the connecting hole 281.

[0451] It can be understood that the shape of the second conductive member 820 should be conducive to improving its conductivity and connection stability.

[0452] In some embodiments, referring to FIG. 35 to FIG. 41 , the second conductive member 820 is provided with a conductive through-hole 821 extending along the second direction Y, the first conductive member 810 is passed through the conductive through-hole 821 , and an interference fit is formed between the first conductive member 810 and the inner wall of the conductive through-hole 821 .

[0453] This is beneficial for increasing the contact surface between the first conductive member 810 and the second conductive member 820 , improving the friction between the two, and maintaining a stable relative position between the two.

[0454] It is understandable that there is an interference fit between the inner wall of the conductive through hole 821 and the first conductive member 810 , and the first conductive member 810 is difficult to insert into the conductive through hole 821 .

[0455] In some embodiments, referring to Figures 36, 38, 39 to 41, the second conductive member 820 is provided with a deformation groove 822, which connects the conductive through-hole 821 and the outside of the second conductive member 820 along the third direction Z. The second direction Y is orthogonal to the third direction Z, and the third direction Z can be parallel to or intersect with the first direction X.

[0456] By providing the deformation groove 822, the structural strength of the second conductive member 820 can be reduced, so that when the first conductive member 810 is inserted into the conductive through-hole 821, the gap of the deformation groove 822 can be enlarged, thereby expanding the conductive through-hole 821. While facilitating the insertion of the first conductive member 810 into the conductive through-hole 821, the second conductive member 820 can utilize the elastic contraction of its own material to maintain fit with the first conductive member 810, thereby improving the connection stability between the first conductive member 810 and the second conductive member 820.

[0457] In some embodiments, referring to FIG. 39 , the deformation groove 822 extends along the second direction Y to both ends of the conductive through hole 821 , thereby facilitating adaptation to different insertion depths of the first conductive member 810 in the conductive through hole 821 .

[0458] In some embodiments, referring to Figures 35 to 41 , the second conductive member 820 includes a cylindrical portion 823. The inner space of the cylindrical portion 823 forms a conductive through-hole 821. The cylindrical portion 823 is sandwiched between the inner wall of the communication hole 281 and the first conductive member 810. In other words, the cylindrical portion 823 is inserted into the communication hole 281, and the first conductive member 810 is inserted into the conductive through-hole 821.

[0459] The first conductive member 810 is inserted into the conductive through hole 821, that is, the cylindrical portion 823 is arranged around the outer wall of the first conductive member 810 perpendicular to the second direction Y, which is beneficial to increasing the contact surface between the first conductive member 810 and the second conductive member 820, which is beneficial to increasing the friction between the two and is more beneficial to maintaining the relative position between the two stable.

[0460] The cylindrical portion 823 is inserted into the connecting hole 281, that is, the inner wall of the connecting hole 281 is arranged on the outer wall of the cylindrical portion 823 perpendicular to the second direction Y, which is beneficial to increase the contact surface between the inner wall of the connecting hole 281 and the second conductive part 820, which is beneficial to increase the friction between the two and is more beneficial to keep the relative position between the two stable.

[0461] In this way, by setting the cylindrical portion 823 on the second conductive member 820, it is more conducive to stabilizing the relative positions between the first conductive member 810 and the second conductive member 820, and between the second conductive member 820 and the inner wall of the connecting hole 281, which is beneficial to the stability of the electrical connection between the first conductive member 810 and the second conductive member 820.

[0462] The cylindrical portion 823 is cylindrical.

[0463] It can be understood that the cross-sectional shape of the conductive through hole 821 perpendicular to the second direction Y is the same as the cross-sectional shape of the first conductive member 810 perpendicular to the second direction Y.

[0464] The specific shapes of the cross-sectional shape of the conductive through hole 821 perpendicular to the second direction Y and the cross-sectional shape of the first conductive member 810 perpendicular to the second direction Y are not limited, for example, both are circular, so as to reduce the probability of stress concentration during the insertion of the first conductive member 810 into the conductive through hole 821 and damage to both.

[0465] It can be understood that the cross-sectional shape of the outer surface of the cylindrical portion 823 perpendicular to the second direction Y is the same as the cross-sectional shape of the communicating hole 281 perpendicular to the second direction Y.

[0466] The specific shapes of the cross-sectional shape of the outer surface of the cylindrical portion 823 perpendicular to the second direction Y and the cross-sectional shape of the connecting hole 281 perpendicular to the second direction Y are not limited, for example, both are circular, so as to reduce the probability of stress concentration causing damage to the cylindrical portion during the insertion of the first conductive member 810 into the conductive through hole 821.

[0467] The specific manufacturing method of the cylindrical portion 823 is not limited. For example, the copper sheet is wound around a straight line extending along the second direction Y as the rotation axis to form the cylindrical portion 823, and deformation grooves 822 are formed along the circumferential intervals of the winding. The manufacturing process is simple and the manufacturing cost is low.

[0468] It is understandable that, since the cylindrical portion 823 is a hollow structure, the cylindrical portion 823 is easily deformed under the action of external shear force and is not easy to restore to its original shape.

[0469] In some embodiments, referring to Figures 39 to 41 , the second conductive member 820 further includes a connecting piece 824, which is electrically connected to the power supply assembly 300. In other words, the connecting piece 824 is electrically connected to the cylindrical portion 823, so that current can be transferred from the power supply assembly 300 to the cylindrical portion 823 via the connecting piece 824.

[0470] The connecting piece 824 is a sheet-like structure, which can be easily bent along its thickness direction to achieve electrical connection with the power supply component 300, reducing the assembly precision requirements and helping to improve assembly efficiency; it prevents the power supply component 300 from directly contacting the cylindrical portion 823 and exerting force on the cylindrical portion 823, causing deformation of the cylindrical portion 823.

[0471] In some embodiments, referring to Figures 39 to 41, the cylindrical portion 823 is located in the connecting hole 281, and the connecting piece 824 is provided at one end of the cylindrical portion 823 close to the power supply component 300 and extends out of the connecting hole 281 to be electrically connected to the power supply component 300.

[0472] The cylindrical portion 823 is completely located in the communicating hole 281 , thereby shielding the cylindrical portion 823 and reducing the probability of deformation caused by collision between the cylindrical portion 823 and an external object during assembly.

[0473] In some embodiments, referring to Figures 38 and 41, one of the second conductive member 820 and the first conductive member 810 is provided with a positioning protrusion 825, and the other is provided with a positioning groove 811, and the positioning protrusion 825 and the positioning groove 811 cooperate with each other to enable the second conductive member 820 to engage with the first conductive member 810 in a stop manner.

[0474] In this way, the inner wall of the positioning groove 811 and the stopper cooperation between the positioning protrusion 825 limit the relative movement tendency between the first conductive member 810 and the second conductive member 820, so that the relative position of the two remains stable, which is conducive to maintaining the electrical connection between the two.

[0475] In some embodiments, the positioning protrusion 825 protrudes perpendicularly to the second direction Y, and the positioning groove 811 is open on one side perpendicular to the second direction Y, so that the first conductive member 810 and the second conductive member 820 are engaged with each other along the second direction Y to limit the tendency of relative movement between the first conductive member 810 and the second conductive member 820 along the second direction Y.

[0476] In some embodiments, the positioning groove 811 is an annular groove with a straight line extending along the second direction Y as the rotation axis, so that during the assembly of the first conductive member 810 and the second conductive member 820, the positioning protrusion 825 can be accurately inserted into the positioning groove 811, thereby reducing the assembly difficulty and improving the assembly efficiency.

[0477] The specific number of the positioning protrusions 825 is not limited and can be one or more. In an embodiment where there are multiple positioning protrusions 825, the multiple positioning protrusions 825 are circumferentially spaced about a straight line extending along the second direction Y. This helps to ensure uniform force between the first conductive member 810 and the second conductive member 820, and better maintain the stability of the relative position between the two.

[0478] The specific method of forming the positioning protrusion 825 is not limited.

[0479] For example, in an embodiment where the positioning protrusion 825 is located on the second conductive member 820, referring to FIG39, the material of the second conductive member 820 is copper, and the positioning protrusion 825 is formed on the other side by stamping on the side of the second conductive member 820 facing away from the first conductive member 810, thereby utilizing the good ductility of copper to simplify the manufacturing process of the positioning protrusion 825 and improve production efficiency.

[0480] 39 and 41 , in an embodiment with a cylindrical portion 823 , the positioning protrusion 825 is located on the inner wall of the conductive through-hole 821 , so that the second conductive member 820 can directly cooperate with the positioning protrusion 825 and the positioning groove 811 during the insertion process of the conductive through-hole 821 , thereby simplifying the assembly steps.

[0481] It can be understood that it is necessary to suppress the relative movement between the inner wall of the communication hole 281 and the second conductive member 820 .

[0482] In some embodiments, referring to FIG. 38 , FIG. 40 and FIG. 41 , the second conductive member 820 includes a deformation portion 826 , and the deformation portion 826 can be elastically deformed so that the deformation portion 826 abuts against the inner wall of the communication hole 281 .

[0483] In this way, the friction force generated by the abutment between the deformation portion 826 and the inner wall of the connecting hole 281 suppresses the tendency of relative movement between the second conductive member 820 and the bracket 200, thereby helping to improve the connection stability between the second conductive member 820 and the first conductive member 810.

[0484] The specific method of forming the deformation portion 826 is not limited.

[0485] In some embodiments, referring to Figures 38, 40, and 41, the second conductive member 820 is provided with a stop spring 827. A first end 8271 of the stop spring 827 is connected to the second conductive member 820 along the second direction Y, and a second end 8272 of the stop spring 827 is separated from the second conductive member 820 along the second direction Y. The stop spring 827 is elastically deformable so as to abut against the inner wall of the communication hole. In other words, the stop spring 827 forms the deformation portion 826.

[0486] The second end 8272 of the elastic piece is located on a side of the first end 8271 of the elastic piece close to the inner wall of the communicating hole 281. In other words, the second end 8272 of the elastic piece is used to abut against the inner wall of the communicating hole 281.

[0487] The stop spring 827 undergoes elastic deformation, allowing the spring's second end 8272 to move. When the second conductive member 820 is sandwiched between the inner wall of the connecting hole 281 and the first conductive member 810, the inner wall of the connecting hole 281 squeezes the stop spring 827. The distance perpendicular to the second direction Y between the spring's second end 8272 and the spring's first end 8271 is smaller than when the second conductive member 820 is not sandwiched between the inner wall of the connecting hole 281 and the first conductive member 810. This causes elastic potential energy to accumulate in the stop spring 827. Driven by this elastic potential energy, the spring's second end 8272 tends to move toward the inner wall of the connecting hole 281, thereby maintaining contact with the inner wall of the connecting hole 281.

[0488] On the one hand, under the action of elastic potential energy, the contact force perpendicular to the second direction Y between the inner wall of the connecting hole 281 and the second end 8272 of the spring is increased, thereby increasing the friction between the two, which is beneficial to suppressing the relative movement between the inner wall of the connecting hole 281 and the second conductive part 820; on the other hand, relative movement occurs between the inner wall of the connecting hole 281 and the second conductive part 820. Under the action of elastic potential energy, the second end 8272 of the spring can scrape against the inner wall of the connecting hole 281, or even insert into the inner wall of the connecting hole 281, thereby suppressing the relative movement between the inner wall of the connecting hole 281 and the second conductive part 820.

[0489] The specific number of the stopping springs 827 is not limited and can be one or more.

[0490] It is understandable that the relative positional relationship between the first end 8271 of the elastic piece and the second end 8272 of the elastic piece is related to the assembly relationship of the atomization device M10. For example, the second end 8272 of the elastic piece is located on the side of the first end 8271 of the elastic piece close to the connecting piece 824.

[0491] Exemplarily, referring to FIG. 38 , the second end 8272 of the spring is located on a side of the first end 8271 of the spring along the second direction Y away from the atomization mechanism M12 .

[0492] In this way, when the second conductive member 820 is installed into the connecting hole 281 from the opening of the end of the connecting hole 281 away from the atomizing mechanism M12 along the second direction Y, the inner wall of the connecting hole 281 contacts the second end 8272 of the elastic sheet and applies a friction force from the first end 8271 of the elastic sheet to the second end 8272 of the elastic sheet, thereby reducing the scraping force between the second end 8272 of the elastic sheet and the inner wall of the connecting hole 281, which is conducive to the installation of the second conductive member 820 into the connecting hole 281; and when the first conductive member 810 is installed from the connecting hole 281 along the second direction Y close to the atomizing mechanism M12 During the process of installing the opening at one end into the connecting hole 281, the first conductive member 810 applies a force from the first end 8271 of the spring clip to the second end 8272 of the spring clip on the second conductive member 820, so that the inner wall of the connecting hole 281 contacts the second end 8272 of the spring clip and applies a friction force from the second end 8272 of the spring clip to the first end 8271 of the spring clip, thereby increasing the scraping force between the second end 8272 of the spring clip and the inner wall of the connecting hole 281, thereby reducing the probability of the second conductive member 820 moving along the second direction Y during the insertion of the first conductive member 810.

[0493] In some embodiments, referring to FIG. 40 , the second conductive member 820 defines a receiving hole 828 extending perpendicularly to the second direction Y, and the first end 8271 of the elastic piece is connected to the inner wall of the receiving hole 828 .

[0494] In this way, when the stopping spring 827 is elastically deformed, the accommodating hole 828 can accommodate at least part of the stopping spring 827, thereby helping to reduce the size of the second conductive member 820 perpendicular to the second direction Y, making the structure of the second conductive member 820 more compact.

[0495] In some embodiments, the accommodating hole 828 can fully accommodate the stop spring 827, thereby increasing the stroke of the second end 8272 of the spring perpendicular to the second direction Y, and further accumulating more elastic potential energy, thereby increasing the friction between the stop spring 827 and the inner wall of the connecting hole 281, which is beneficial to the stability of the relative position between the second conductive member 820 and the inner wall of the connecting hole 281.

[0496] The specific method of forming the stop spring 827 is not limited.

[0497] Exemplarily, a partial area of ​​the second conductive member 820 is punched out to separate a portion of the area from other portions to form the spring second end 8272 , thereby forming the stop spring 827 .

[0498] In some embodiments having a cylindrical portion 823 , referring to FIG. 40 , the stop spring 827 is located in the cylindrical portion 823 .

[0499] It is understandable that during long-term use of the atomizing device M10 , foreign matter may enter the communicating hole 281 , thereby adversely affecting the electrical connection between the second conductive member 820 and the first conductive member 810 .

[0500] In some embodiments, referring to Figures 38, 39 and 41, the second conductive member 820 is provided with a shielding piece 829, which is located in the connecting hole 281. When the first conductive member 810 is inserted into the connecting hole 281, the shielding piece 829 is located between the opening of the connecting hole 281 on the side close to the power supply component 300 and the first conductive member 810. The shielding piece 829 is used to cover at least part of the connecting hole 281.

[0501] That is to say, one end of the first conductive member 810 close to the power supply mechanism M11 along the second direction Y is located in the connecting hole 281, and the blocking piece 829 can block foreign matter entering the connecting hole 281 from the opening on the side of the connecting hole 281 close to the power supply component 300, so as to reduce the probability of foreign matter entering the connection position between the first conductive member 810 and the second conductive member 820, causing a short circuit between the two, and at the same time, it can block the user's line of sight.

[0502] Referring to Figure 41, the blocking piece 829 is spaced apart from the inner wall of the connecting hole 281 to form a gap connecting the spaces on both sides of the blocking piece 829 along the second direction Y, which is conducive to reducing the manufacturing difficulty of the blocking piece 829; or, the blocking piece 829 is sealed and fitted with the inner wall of the connecting hole 281 to isolate the spaces on both sides of the blocking piece 829 along the second direction Y from each other, thereby improving the blocking effect of the blocking piece 829 on foreign objects of various sizes.

[0503] In some embodiments having a conductive through hole 821 , referring to FIG. 41 , the shielding piece 829 is located at an opening position at one end of the conductive through hole 821 along the second direction Y.

[0504] In some embodiments where a receiving hole 828 is provided, referring to FIG. 38 , a shielding piece 829 is located between the opening of the connecting hole 281 on the side close to the power supply component 300 and the receiving hole 828 to reduce the probability of foreign matter entering the receiving hole 828 and affecting the elastic deformation of the stop spring 827 .

[0505] In some embodiments, referring to FIG. 36 , a support column 284 is provided at one end of the bracket 200 close to the atomization mechanism M12 . The support column 284 extends along the second direction Y and abuts against the atomization mechanism M12 along the second direction Y. At least a portion of the communication hole 281 is located in the support column 284 .

[0506] On the one hand, by having at least a portion of the connecting hole 281 located on the support column 284, the size of the other portion of the bracket 200 close to the end of the atomization mechanism M12 along the second direction Y is reduced, which helps to make the structure of the bracket 200 more compact; on the other hand, by having the support column 284 abut against the atomization mechanism M12, the insertion depth of the first conductive member 810 in the connecting hole 281 can be limited, thereby reducing the probability that the first conductive member 810 fails to achieve electrical connection with the second conductive member 820 or is inserted too deeply, causing damage to other components in the power supply mechanism M11.

[0507] The specific structure of the bracket 200 is not limited.

[0508] For example, referring to Figures 36, 42 and 43, the bracket 200 includes a mounting bracket 270 and a mounting seat 280, the mounting bracket 270 is provided with a accommodating cavity 240 and a mounting hole 271, the mounting hole 271 passes through the mounting bracket 270 along the second direction Y to connect the accommodating cavity 240 and the outside of the mounting bracket 270, at least a portion of the mounting seat 280 is passed through the mounting hole 271 along the second direction Y, and the connecting hole 281 is provided in the mounting seat 280.

[0509] The power supply assembly 300 is disposed in the accommodating cavity 240 . The accommodating cavity 240 not only provides an installation location for the power supply assembly 300 , but also plays a certain protective role for the power supply assembly 300 .

[0510] During the assembly process, the second conductive member 820 may be first installed into the communicating hole 281 of the mounting seat 280 , and then the mounting seat 280 may be installed into the mounting hole 271 .

[0511] In this way, during the process of installing the second conductive member 820, the interference of components such as the inner wall of the accommodating cavity 240 and the power supply assembly 300 is reduced, and there is a larger operating space, which is convenient for personnel or machinery to operate and is conducive to improving assembly efficiency.

[0512] In some embodiments, referring to FIG. 36 and FIG. 43 , the mounting seat 280 is provided with a stop surface 282 , which is located on a side of the mounting bracket 270 close to the atomization mechanism M12 along the second direction Y and cooperates with the mounting bracket 270 to stop along the second direction Y.

[0513] In this way, on the one hand, the relative position between the mounting seat 280 and the mounting bracket 270 along the second direction Y is constrained, reducing the probability of relative movement between the two and adversely affecting other components in the atomization device M10; on the other hand, the mounting seat 280 can be supported by the mounting bracket 270 along the second direction Y, so as to reduce the probability that the mounting seat 280 moves along the second direction Y during the process of inserting the first conductive member 810 into the connecting hole 281, thereby making it impossible to achieve electrical connection between the first conductive member 810 and the second conductive member 820, and reducing the probability of the mounting seat 280 being deformed by force and damaged.

[0514] The specific structure of the mounting base 280 is not limited.

[0515] For example, referring to Figures 36 and 44, the mounting base 280 includes a stop plate 283, a support column 284 and a mounting column 284. The support column 284 is located on one side of the stop plate 283 away from the power supply component 300 along the second direction Y, and the mounting column 284 is located on the other side. The support column 284 and the mounting column 284 both extend along the second direction Y. The mounting column 284 is passed through the mounting hole 271. A stop surface 282 is formed on the surface of one side of the stop plate 283 close to the power supply component 300, and the connecting hole 281 passes through the stop plate 283, the support column 284 and the mounting column 284.

[0516] The mounting post 284 is inserted into the mounting hole 271 so that a stop fit is achieved between the surface of the mounting post 284 and the inner wall of the mounting hole 271 , thereby limiting the position of the mounting seat 280 perpendicular to the second direction Y.

[0517] The stop plate 283 realizes the stopping cooperation between the mounting bracket 270 and the mounting seat 280, and can also block the gap between the mounting column 284 and the inner wall of the mounting hole 271, thereby reducing the risk of foreign matter entering.

[0518] It can be understood that, in the projection plane perpendicular to the second direction Y, the projection of the mounting column 284 and the projection of the support column 284 are both located within the projection range of the stop plate 283 , so that the surface of the stop plate 283 forms a stop surface 282 .

[0519] 42 and 44 , the cross-sectional shape of the mounting post 284 perpendicular to the second direction Y and the cross-sectional shape of the mounting hole 271 perpendicular to the second direction Y are both circular to reduce the probability of damage due to stress concentration.

[0520] In some embodiments, referring to FIG. 44 , at least a portion of the outer side surface of the support column 284 perpendicular to the second direction Y is a conical surface, and its cross-sectional area perpendicular to the second direction Y gradually increases in the direction away from the atomization mechanism M12, so as to improve the structural strength of the support column 284 and reduce the probability of the support column 284 being deformed by the pressure of the atomization mechanism M12, resulting in distortion of the connecting hole 281.

[0521] It is understood that the number of support columns 284, mounting columns 284, and communication holes 281 is the same, and the three correspond one to one. Each support column 284 and each mounting column 284 are located on the same stop plate 283. The stop plate 283 connects each support column 284 and each mounting column 284, thereby fixing the relative position between each support column 284 and each mounting column 284.

[0522] In some embodiments having multiple support columns 284, referring to FIG. 44 , the mounting base 280 further includes a reinforcing rib 286, which is connected between at least two support columns 284. The reinforcing rib 286 suppresses the probability of the support columns 284 being twisted and deformed under the pressure of the atomization mechanism M12, thereby improving the overall structural strength of the mounting base 280.

[0523] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0524] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the patent disclosed herein shall be determined by the appended claims.
