In some embodiments, the mounting assembly 200 includes a top cover 210 and a bottom cover 220, the atomizing assembly 300 is mounted between the bottom cover 220 and the top cover 210, the top cover 210 of the mounting assembly 200, the body portion 110 of the housing 100 and the insertion portion 120 jointly partition the upper portion of the inner cavity to form the reservoir 130, and the liquid is stored in the reservoir 130. The upper cover 210 may further be sleeved with a sealing plug 230, and the sealing plug 230 is pressed between the body 110 and the upper cover 210, so as to improve the sealing performance of the reservoir 130 and prevent the liquid from leaking from the gap between the body 110 and the upper cover 210.

Referring to fig. 1 to 7, the base 220 includes a supporting portion 221 and a limiting portion 222 connected to each other, the air inlet channel 13 is disposed on the supporting portion 221, the air inlet channel 13 is communicated with the outside and the air outlet channel 140, and when a user sucks, the outside air enters from the air inlet channel 13 and carries smoke into the air outlet channel 140 to be sucked by the user.

Of course, the locking hole 222b is disposed on the upper cover 210, and the protrusion 213 is disposed on the position-limiting portion 222, so that the locking connection between the upper cover 210 and the base 220 can be realized.

In some embodiments, the atomizing assembly 300 includes an atomizing core 310, a sealing member 320, and a heating element, the atomizing core 310 may be a porous ceramic atomizing core 310, that is, the atomizing core 310 is made of a porous ceramic material, so that a large number of micropores exist in the atomizing core 310 and have a certain porosity, the porosity may be defined as a percentage of a volume of a pore in an object to a total volume of the material in a natural state, and a value of the porosity of the atomizing core 310 may range from 20% to 70%, for example, a specific value thereof is 20%, 40%, 50%, or 70%. The atomizing core 310 has a capillary action due to the existence of the micropores, so that the liquid in the liquid storage cavity 130 permeates into the atomizing core 310 under the capillary action, and the atomizing core 310 has functions of guiding and buffering the liquid.

Referring to fig. 2 to 4 and fig. 12, the atomizing core 310 includes a sidewall 311 and a bottom wall 312, the sidewall 311 and the bottom wall 312 together define a buffer chamber 314, and the sidewall 311 is connected to an upper portion of the bottom wall 312. The upper cover 210 of the mounting assembly 200 is provided with a liquid inlet channel 212, the liquid inlet channel 212 can communicate the buffer cavity 314 and the reservoir cavity 130, and the liquid in the reservoir cavity 130 can flow into the buffer cavity 314 through the liquid inlet channel 212. The sidewall 311 has a side circumferential surface 311a and a top surface 311b, the top surface 311b is disposed horizontally, the side circumferential surface 311a is disposed vertically, and the top surface 311b is connected between the side circumferential surface 311a and the sidewall 314a of the buffer cavity 314, it can also be understood that the side circumferential surface 311a is disposed opposite to the sidewall 314a of the buffer cavity 314, and the top surface 311b is disposed opposite to the bottom wall 314b of the buffer cavity 314. The horizontal distance between the side circumferential surface 311a and the side wall 314a may be defined as the wall thickness h of the side wall 311. The bottom surface of the bottom wall 312 is an atomizing surface 312a, and obviously, the atomizing surface 312a is further away from the reservoir 130 relative to the side peripheral surface 311a, and the atomizing surface 312a and the top surface 311b face opposite directions, i.e., they are disposed opposite to each other. The heating element is disposed on the atomization surface 312a, the liquid in the buffer chamber 314 can continuously permeate into the atomization surface 312a through the inside of the bottom wall 312, and when the heating element generates heat, the liquid on the atomization surface 312a absorbs the heat to atomize and form smoke. The atomizing core 310 made of the porous ceramic material has good high temperature resistance, and the liquid permeating the atomizing core 310 does not generate chemical reaction with the atomizing core 310 under the high temperature condition, so that the waste of the liquid caused by the participation of unnecessary chemical reaction is prevented, and the generation of harmful substances can also be avoided. The atomization surface 312a and the bottom wall 314b of the buffer cavity 314 face opposite to each other, that is, they are disposed opposite to each other, and the vertical distance between the bottom wall 314b and the atomization surface 312a can be defined as the wall thickness H of the bottom wall 312, in this case, the wall thickness H of the side wall 311 is smaller than the wall thickness H of the bottom wall 312.

Referring to fig. 6 to 8 and fig. 12, in some embodiments, for example, referring to fig. 13, the sealing member 320 may only include the first sealing portion 322, the first sealing portion 322 is horizontally disposed and located on the top surface 311b of the sidewall portion 311, at this time, the first sealing portion 322 is pressed between the upper cover 210 and the top surface 311b, that is, the first sealing portion 322 covers the top surface 311b, a through hole 322a is formed in the first sealing portion 322, the through hole 322a communicates the buffer cavity 314 and the liquid inlet channel 212, and the liquid in the liquid storage cavity 130 flows into the buffer cavity 314 through the liquid inlet channel 212 and the through hole 322a in sequence. The first sealing member 321 does not form a sleeve (i.e., wrap) on the side circumferential surface 311a of the atomizing core 310, so that the air entering the air inlet channel 13 from the outside can directly penetrate the side circumferential surface 311a into the buffer chamber 314 through the side wall 311, and finally enters the reservoir chamber 130 from the buffer chamber 314. For another example, the sealing member 320 further includes a second sealing portion 321 connected to the first sealing portion 322, the second sealing portion 321 is vertically disposed and sleeved on the lateral peripheral surface 311a of the lateral wall portion 311, that is, the second sealing portion 321 covers the lateral peripheral surface 311a, so that the second sealing portion 321 is pressed between the atomizing core 310 and the upper cover 210 and the base 220. By arranging the second sealing portion 321, the liquid in the liquid inlet channel 212 can be effectively prevented from leaking through the gap between the atomizing core 310 and the upper cover 210, and the atomizer 10 is prevented from oil leakage. The second sealing portion 321 has a through hole 321a, and the through hole 321a can extend along the horizontal direction, and the through hole 321a is the first air flow channel 12. For another example, the seal 320 may further include a third seal portion 323 connected to a lower end of the second seal portion 321, the side wall portion 311 may have a stepped surface 311c bent and connected to the side circumferential surface 311a, the stepped surface 311c may be horizontally disposed and perpendicular to the side circumferential surface 311a, the stepped surface 311c and the atomizing surface 312a may be oriented in the same direction and both may be disposed downward, and the third seal portion 323 may be in contact between the stepped surface 311c and the supporting surface 221b of the base 220, that is, the third seal portion 323 may cover the stepped surface 311 c. When the seal 320 includes the second sealing portion 321, the first sealing portion 322, and the third sealing portion 323 at the same time, the sealing performance of the seal 320 is further improved, and the seal 320 simultaneously forms a wrapping effect on the atomizing core 310 from both the circumferential direction and the axial direction, which further improves the mounting stability of the seal 320, and at the same time, the seal 320 forms a protective effect on the atomizing core 310.

The sealing member 320 may be a silicone sealing member, that is, the sealing member 320 is made of a silicone material, and the sealing member 320 has a good heat insulation performance, so as to prevent heat generated on the atomizing core 310 from being transferred to the housing 100, and prevent a user from generating a hot feeling when holding the housing 100. In addition, the heat loss on the atomizing core 310 is avoided, and the heat generated by the heating body is fully used for atomizing the liquid as far as possible, namely, the utilization rate of energy is improved.

Referring to fig. 6 to 9, the base 220 of the mounting assembly 200 is provided with a first groove 221a, the first groove 221a is formed by a portion of the supporting surface 221b being recessed downward by a predetermined depth, the first groove 221a is communicated with the air inlet channel 13, the second sealing portion 321 and the third sealing portion 323 of the sealing member 320 can cover a portion of an opening of the first groove 221a on the supporting surface 221b, the supporting portion 221, the second sealing portion 321 and the upper cover 210 of the base 220 together define a cavity 101, the cavity 101 is simultaneously communicated with the first groove 221a and the first air flow channel 12, and at this time, the first groove 221a and the cavity 101 together form the second air flow channel 11. Of course, the first groove 221a may be opened on the sealing member 320. When the external air enters the first air flow channel 12 through the air inlet channel 13, the first groove 221a and the cavity 101 in sequence, because the sidewall 311 of the atomizing core 310 has certain air permeability and the sealing member 320 separates the communication between the air inlet channel 13 and the liquid storage cavity 130, the air in the first air flow channel 12 will continue to penetrate through the sidewall 311 and rapidly enter the buffer cavity 314, i.e. be guided into the buffer cavity 314 through the micro-holes in the sidewall 311. When the liquid in the liquid storage cavity 130 decreases, the air entering the buffer cavity 314 fills the space of the liquid storage cavity 130 released by the decrease of the liquid (the path indicated by the dotted arrow in fig. 9 is the flow path of the air), so as to increase the air pressure in the liquid storage cavity 130, so that the liquid in the liquid storage cavity 130 can quickly reach the atomizing surface 312a for atomization (the path indicated by the solid arrow in fig. 9 is the flow path of the liquid), i.e., the liquid is discharged smoothly, thereby preventing the atomizing core 310 from being burnt due to insufficient supply of the liquid, finally avoiding the burnt smell and other harmful substances generated by the burning, improving the suction experience of the user, and simultaneously prolonging the service life of the whole atomizing assembly 300.

With the conventional atomizing assembly 300, the air in the air inlet channel 13 directly enters the buffer chamber 314 from the atomizing surface 312a through the bottom wall 312, i.e., is guided into the buffer chamber 314 through the micro-holes in the bottom wall 312. However, the pore diameters of the micropores of the bottom wall 312 are smaller and the extending directions are not uniform, and meanwhile, under the action of gravity, in addition, the liquid is atomized at the atomization surface 312a, the liquid in the buffer cavity 314 flows toward the atomization surface 312a more easily (i.e., flows downward), so that the micropores of the bottom wall 312 are filled with more liquid, and therefore, the flow resistance of the air in the bottom wall 312 is larger, so that the air entering the liquid storage cavity 130 through the buffer cavity 314 in a unit time is insufficient to form sufficient air pressure, and the liquid in the liquid storage cavity 130 cannot reach the atomization surface 312a quickly, i.e., the liquid feeding is not smooth, and finally, the atomization core 310 is dried. With the above embodiment, since the liquid is not easily affected by gravity and fills the pores of the sidewall 311, the flow resistance of the air penetrating the sidewall 311 from the side circumferential surface 311a is reduced, and meanwhile, the wall thickness H of the sidewall 311 is smaller than the wall thickness H of the bottom wall 312, and the path of the air passing through the sidewall 311 is shorter, so the flow resistance and the path of the air passing through the sidewall 311 are smaller, so that the time for the air to enter the buffer cavity 314 through the sidewall 311 is substantially shorter than the time for the air to enter the buffer cavity 314 through the bottom wall 312, therefore, a greater amount of air enters the buffer cavity 314 from the first air flow channel 12 through the sidewall 311 in a unit time, and finally enters the reservoir 130 to form a relatively higher air pressure, thereby ensuring that the liquid in the reservoir 130 quickly reaches the atomization surface 312a to prevent dry burning.

In order to prevent the liquid from leaking out of the atomizing assembly 300 through the first air flow channel 12 (i.e., the through hole 321a) of the second sealing portion 321, the cross-sectional dimension of the first air flow channel 12 is controlled to be between 0.1mm and 2mm, and may be 0.1mm, 0.5mm, 0.8mm, or 2 mm. When the viscosity of the liquid increases, the cross-sectional size of the first air flow path 12 may be appropriately increased, whereas when the viscosity of the liquid decreases, the cross-sectional size of the first air flow path 12 may be appropriately decreased.

Referring to fig. 6 to 7, and fig. 10 to 11, in some embodiments, the atomizing assembly 300 further includes a liquid-blocking air-permeable member 330, the liquid-blocking air-permeable member 330 is substantially in a sheet structure, the liquid-blocking air-permeable member 330 may include a tetrafluoroethylene sheet, an arene sheet, or a plant fiber sheet, that is, the liquid-blocking air-permeable member 330 may be supported by materials such as tetrafluoroethylene, arene, or plant fiber, and the plant fiber may be a non-woven fabric, organic cotton, or ecological cotton. By adopting the materials, air can rapidly permeate through the liquid-proof and air-permeable piece 330, namely, the air flows through the inside of the liquid-proof and air-permeable piece 330 from one side of the liquid-proof and air-permeable piece 330 and enters the other side of the liquid-proof and air-permeable piece 330, and the liquid-proof and air-permeable piece 330 has good air permeability; meanwhile, the liquid cannot penetrate through the liquid-proof and gas-permeable member 330, that is, the liquid cannot flow through the inside of the liquid-proof and gas-permeable member 330 from one side of the liquid-proof and gas-permeable member 330 and enter the other side of the liquid-proof and gas-permeable member 330, and the liquid-proof and gas-permeable member 330 has good liquid-proof performance. Therefore, the liquid-barrier air-permeable member 330 has good liquid-barrier properties and air-permeable properties. Moreover, on the basis of ensuring the liquid-proof performance and the air permeability, the liquid-proof air-permeable member 330 made of the above materials can be very thin, so that the volume and the installation space of the liquid-proof air-permeable member 330 are reduced, and the whole atomization assembly 300 is more compact in structure. The thickness of the liquid-barrier gas-permeable member 330 ranges from 0.5mm to 2mm, and the specific value thereof may be 0.5mm, 0.9mm, 1mm, 2mm, or the like.

The liquid-proof air-permeable member 330 may be accommodated in the cavity 101 and may completely fill the entire cavity 101, such that the liquid-proof air-permeable member 330 is pressed between the second sealing portion 321 and the entire mounting assembly 200, and the liquid-proof air-permeable member 330 blocks the port of the first air flow channel 12 far from the side wall portion 311. At this time, the first groove 221a constitutes the second air flow channel 11, the first groove 221a corresponds to the bottom surface of the liquid-barrier air-permeable member 330, and the air in the first groove 221a enters the inside of the liquid-barrier air-permeable member 330 from the bottom surface of the liquid-barrier air-permeable member 330 and reaches the first air flow channel 12, so that the air in the air intake channel 13 sequentially passes through the first groove 221a, the liquid-barrier air-permeable member 330, the first air flow channel 12 and the side wall portion 311 and finally enters the reservoir chamber 130. Of course, the upper cover 210 may further be provided with a second groove 211, the second groove 211 extends along the vertical direction and is communicated with the first groove 221a, the second groove 211 corresponds to the side surface of the liquid-proof and gas-permeable member 330, and at this time, the first groove 221a and the second groove 211 together form the second air flow channel 11, the air in the first groove 221a also enters the inside of the liquid-proof air-permeable member 330 from the bottom surface of the liquid-proof air-permeable member 330 and reaches the first air flow channel 12, the air in the second groove 211 enters the inside of the liquid-proof air-permeable member 330 from the side surface of the liquid-proof air-permeable member 330 and reaches the first air flow channel 12, that is, the air in the second air flow channel 11 can enter the inside of the liquid-proof air-permeable member 330 from both the bottom surface and the side surface of the liquid-proof air-permeable member 330, this further increases the velocity of air entering the first air flow channel 12 through the liquid barrier and gas permeable member 330 and ultimately reaching the reservoir 130.
