The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0026] The embodiment of the present application discloses an atomization assembly 1, which is applied to an atomization device to heat atomization liquid and generate aerosol for use by a user.

[0027] The atomizer assembly 1 of the present embodiment of the present application, please refer to Figures 1 to 5 The atomizer assembly 1 includes an atomizer housing 10, an atomizer base 40 and a blocking member 50. The atomizer housing 10 has an atomizer channel 14 for aerosol to flow out. The atomizer base 40 is sealed and inserted with the atomizer housing 10 through a first sealing member 20 to form a liquid storage chamber 31 between the atomizer base 40 and the atomizer housing 10. The liquid storage chamber 31 has a liquid storage member 32. The liquid storage member 32 may include liquid storage cotton or other structures capable of absorbing atomized liquid. The atomizer base 40 has an atomizer chamber 46 located at the end of the atomizer channel 14 and connected to the atomizer channel 14. The atomizer chamber 46 is located at the atomizer. The end of the air inlet of the atomization channel 14 is located, so that the aerosol generated by the heated atomized liquid in the atomization chamber 46 can directly flow out along the atomization channel 14, and the atomization chamber 46 and the liquid storage chamber 31 are arranged in the extension direction of the atomization channel 14, and the liquid storage chamber 31 can be arranged around the atomization channel 14. During the use of the atomization device, the air outlet of the atomization channel 14 is located on the upper side of the air inlet of the atomization channel 14, and the liquid storage chamber 31 is located on the upper side of the atomization chamber 46. The atomized liquid in the liquid storage chamber 31 can enter the atomization chamber 46 under the action of gravity, thereby supplying liquid to the atomization chamber 46.

[0028] The atomizer base 40 has an air vent 42, and the liquid storage chamber 31 can be connected to the external space of the atomizer component 1 through the air vent 42. When the air vent 42 is open and the air pressure in the liquid storage chamber 31 is lower than the atmospheric pressure, external air can enter the liquid storage chamber 31 from the air vent 42, thereby achieving a pressure balance inside and outside the liquid storage chamber 31, ensuring that the atomized liquid in the liquid storage chamber 31 can smoothly enter the atomizer chamber 46, and helping to achieve continuous liquid supply to the liquid storage chamber 31, thereby reducing the probability of dry burning and core burnout of the atomizer component 1.

[0029] In one embodiment, please refer to Figures 3 to 5 The vent hole 42 is arranged in the extension direction of the atomizing channel 14, the vent hole 42 connects the liquid storage chamber 31 with the external space of the atomizing assembly 1, the blocking member 50 is located in the vent hole 42, and the blocking member 50 can reciprocate in the vent hole 42 along the extension direction of the atomizing channel 14; during the reciprocating movement of the blocking member 50, the blocking member 50 has a sealing position and a connecting position. When the blocking member 50 is in the connecting position, the blocking member 50 is arranged at an interval with the hole wall surface of the vent hole 42, and the blocking member 50 has no blocking effect on the vent hole 42. The external space of component 1 can be connected to the liquid storage chamber 31 through the air vent 42, and external air can enter the liquid storage chamber 31 along the air vent 42 to balance the pressure difference between the inside and outside of the liquid storage chamber 31; when the sealing component 50 is in the blocking position, the sealing component 50 fits against the wall surface of the air vent 42, and the sealing component 50 blocks the air vent 42. The external space of the atomizer component 1 is isolated from the liquid storage chamber 31, and the sealing component 50 can limit the atomized liquid in the liquid storage chamber 31 from flowing from the air vent 42 to the outside of the atomizer component 1, which helps to reduce the probability of leakage of the atomizer component 1.

[0030] Specifically, when the atomizer assembly 1 is not working, under the action of the external atmospheric pressure and the blocking action of the liquid guide part in the atomizer assembly 1, the atomized liquid in the liquid storage chamber 31 will not enter the atomizer chamber 46, which can effectively reduce the probability of leakage of the atomized liquid; when the atomizer assembly 1 just starts to work, the temperature and pressure in the liquid storage chamber 31 increase, and under the action of the pressure difference between the inside and outside of the liquid storage chamber 31, the atomized liquid in the liquid storage chamber 31 enters the atomizer chamber 46, and the atomizer core heats the atomized liquid to generate an aerosol. Subsequently, when the user inhales, a negative pressure is generated in the atomizer chamber 46, and the negative pressure generates a pressure difference between the liquid storage chamber 31 and the atomizer chamber 46, which increases the amount of atomized liquid entering the atomizer chamber 46.

[0031] In the above process, under the action of the liquid pressure in the liquid storage chamber 31 and the gravity of the sealing member 50, the sealing member 50 is always in the blocking position, which can reduce the probability of the atomized liquid in the liquid storage chamber 31 leaking from the air vent 42 to the outside of the atomizer assembly 1; as the atomized liquid in the liquid storage chamber 31 is consumed, the air pressure in the liquid storage chamber 31 gradually decreases to a negative pressure state, and under the action of the pressure difference between the inside and outside of the liquid storage chamber 31, the sealing member 50 can move from the blocking position to the connecting position, and the air outside the atomizer assembly 1 can enter the liquid storage chamber 31 from the air vent 42 to balance the pressure difference between the inside and outside of the liquid storage chamber 31, ensuring that the atomized liquid in the liquid storage chamber 31 can be continuously supplied to the atomizer chamber 46, which can effectively reduce the probability of dry burning or even core burnt in the atomizer chamber 46.

[0032] For some embodiments, please continue to refer to Figures 3 to 5 The atomizer assembly 1 has an air inlet 4314 connected to the atomizer chamber 46, and the vent hole 42 can connect the air inlet 4314 with the liquid storage chamber 31. Of course, in other embodiments, an opening connected to the outside of the atomizer assembly 1 can be further provided on the atomizer assembly 1, so that the vent hole 42 connects the opening with the liquid storage chamber 31, so that the external air can enter the liquid storage chamber 31 through the vent hole 42 when the sealing member 50 is in the connecting position, thereby achieving the balance of air pressure inside and outside the liquid storage chamber 31.

[0033] For some examples, please refer to Figure 4 and Figure 5The air inlet 4314 is arranged on the atomizing base 40, or in other embodiments, it can also be arranged on the atomizing housing 10, or it can be formed by the atomizing housing 10 and the atomizing base 40. The air inlet 4314 is located at the end of the atomizing assembly 1 in the extending direction of the atomizing channel 14. For example, in a structure in which the air outlet of the atomizing channel 14 is located on the upper side of the air inlet, the air inlet 4314 is located at the bottom end of the atomizing assembly 1. In addition, an air inlet cavity 44 connected to the air inlet 4314 is arranged in the atomizing assembly 1. The air inlet 4314 is connected to the atomizing cavity 46 through the air inlet cavity 44. The air inlet 4314 is also connected to the vent 42 through the air inlet cavity 44. The air inlet cavity 44 can be at the atomizing cavity 46 in the extending direction of the atomizing channel 14. On the side of the cavity 46 facing away from the liquid storage cavity 31, the vent hole 42 can be located between the atomizing cavity 46 and the liquid storage cavity 31 in the extension direction of the atomizing channel 14, or can also correspond to the position of the atomizing cavity 46, so that the air inlet cavity 44 is also located on the side of the vent hole 42 facing away from the liquid storage cavity 31 in the extension direction of the atomizing channel 14; the air outside the atomizing assembly 1 can enter the air inlet cavity 44 from the air inlet port 4314, and then enter the liquid storage cavity 31 from the air inlet cavity 44 along the vent hole 42, so as to balance the air pressure inside and outside the liquid storage cavity 31.

[0034] A liquid absorbent component 45 is provided in the air inlet cavity 44. The liquid absorbent component 45 may be liquid absorbent cotton or other structures with a porous structure that allows gas to pass through and can absorb atomized liquid. The liquid absorbent component 45 can receive and absorb condensed liquid or atomized liquid dripping from the atomization cavity 46 or the atomization channel 14, and can also receive and absorb atomized liquid leaking from the air vent 42 into the air inlet cavity 44, thereby reducing the probability of liquid leakage from the air inlet port 4314.

[0035] For some examples, please refer to Figures 2 to 5 The atomizing shell 10 includes a shell body 11 and an atomizing tube 13. The shell body 11 has an installation cavity. The shell body 11 has an installation opening 12 at one end in the extension direction of the atomizing channel 14, and the other end opening is connected to the atomizing tube 13. The atomizing tube 13 extends toward the installation cavity to enclose the atomizing channel 14. The outlet of the atomizing channel 14 is located at the other end of the shell body 11.

[0036] The atomizing base 40 is inserted and matched with the shell body 11 through the mounting port 12, and the atomizing base 40 is also sealed with the shell body 11 and the atomizing tube 13 through the first sealing member 20, so that a liquid storage chamber 31 arranged around the atomizing channel 14 is enclosed between the atomizing shell 10 and the atomizing base 40. The atomizing base 40 includes a base 43 and a bracket 41 that are separately arranged, the bracket 41 is located in the shell body 11, the bracket 41 is sealed with the atomizing shell 10 through the first sealing member 20, the base 43 is installed at the mounting port 12 of the shell body 11, the base 43 is sealed with the shell body 11, the liquid storage chamber 31 is located between the bracket 41 and the atomizing shell 10, and the vent 42 is located on the bracket 41.

[0037] In one embodiment, please refer to Figure 4 and Figure 5 , the air inlet cavity 44 is located inside the base 43 in the extension direction of the atomization channel 14. The base 43 includes a seat body 431 and a second sealing member 432. The seat body 431 is installed at the installation port 12 of the shell body 11. The seat body 431 can be connected to the shell body 11 by snap-fitting. In the extension direction of the atomization channel 14, the second sealing member 432 is sleeved on the end of the seat body 431 facing the liquid storage cavity 31, so that a cavity is formed between the seat body 431 and the second sealing member 432, and the cavity is the air inlet cavity 44 inside the base 43; the seat body 431 is sealed with the shell body 11 through the second sealing member 432, and the second sealing member 432 has a sealing outer peripheral surface, and the second sealing member 432 is sealed with the inner wall surface of the shell body 11 through its sealing outer peripheral surface.

[0038] In one embodiment, please continue to refer to Figure 4 and Figure 5 The air inlet cavity 44 has a bottom cavity wall 4311 and a top cavity wall 4325 which are arranged at intervals in the extending direction of the atomizing channel 14. The bottom cavity wall 4311 is located on the seat body 431, and the top cavity wall 4325 is located on the second sealing member 432. The bottom cavity wall 4311 of the seat body 431 is provided with a protruding structure 4312 which is protruded toward the air inlet cavity 44.

The air inlet channel 4313 also has an outlet connected to the air inlet cavity 44, and the outlet is arranged at an interval between the bottom cavity wall 4311 of the air inlet cavity 44 in the extension direction of the atomization channel 14. In this way, part of the liquid flowing from the atomization cavity 46 and the air vent 42 to the air inlet cavity 44 can be stored through the air inlet cavity 44, thereby reducing the probability of liquid leakage from the air inlet 4314.

[0039] Furthermore, in one embodiment, a groove 4315 can be provided on the bottom cavity wall 4311 of the seat body 431, and one or more grooves 4315 can be provided, and multiple grooves 4315 are arranged at intervals. The groove 4315 and the liquid absorbent member 45 are enclosed to form a receiving groove, and the liquid overflowing from the liquid absorbent member 45 can be accommodated by the receiving groove, and the liquid absorbent member 45 is covered on the notch of the groove 4315 to seal the liquid in the receiving groove, thereby further reducing the probability of liquid leakage from the air inlet 4314.

[0040] In another embodiment, the second sealing member 432 may be eliminated so that the base 43 only includes a seat body 431, and the seat body 431 is sealed with the shell body 11 via a sealing ring arranged around the seat body 431, or the seat body 431 is made of rubber material, and the outer peripheral surface of the seat body 431 is directly sealed with the inner wall surface of the shell body 11, and the bottom cavity wall 4311 and the top cavity wall 4325 of the air inlet cavity 44 are both located on the seat body 431, or the top cavity wall 4325 of the air inlet cavity 44 is located on the bracket 41.

[0041] For some examples, please refer to Figures 3 to 5 The atomizing assembly 1 is provided with a buffer chamber 47, and the buffer chamber 47 is located between the vent hole 42 and the air inlet chamber 44 in the extension direction of the atomizing channel 14. The buffer chamber 47 connects the vent hole 42 and the air inlet chamber 44. The buffer chamber 47 can reduce the flow rate of the atomized liquid from the vent hole 42 to the air inlet chamber 44, and the buffer chamber 47 can also store part of the atomized liquid leaking from the vent hole 42 to further reduce the probability of leakage of the atomized liquid.

[0042] In one embodiment, in the extension direction of the atomization channel 14, the cache chamber 47 has a first cavity wall 4321 and a second cavity wall 411 arranged at intervals, the first cavity wall 4321 is located on the side of the second cavity wall 411 facing away from the liquid storage chamber 31, the first cavity wall 4321 has an inner convex portion 4322 facing the cache chamber 47, and a first air channel 4323 connecting the air inlet chamber 44 and the cache chamber 47 is provided on the inner convex portion 4322, the first air channel 4323 is arranged in the extension direction of the atomization channel 14, the first air channel 4323 is connected to the cache chamber 47 through a gas outlet 4324, and the gas outlet 4324 and the first cavity wall 4321 are arranged at intervals in the extension direction of the atomization channel 14, so that the volume of the atomized liquid stored in the cache chamber 47 can be increased, thereby reducing the probability of the atomized liquid entering the air inlet chamber 44, and further reducing the probability of leakage of the atomized liquid.

[0043] In one embodiment, a second air channel 412 connecting the air vent 42 and the cache chamber 47 is provided on the second cavity wall 411. In a plane perpendicular to the extension direction of the atomization channel 14, the first air channel 4323 and the second air channel 412 are staggered. This can prevent the atomized liquid entering the cache chamber 47 from the second air channel 412 from directly entering the air inlet chamber 44 along the first air channel 4323, which helps to increase the amount of atomized liquid in the cache chamber 47.

[0044] Of course, in order to further increase the amount of atomized liquid that can be stored in the buffer chamber 47, a liquid absorption component can also be set in the buffer chamber 47 to absorb the atomized liquid, so as to reduce the amount of atomized liquid entering the air inlet chamber 44 due to the shaking of the atomization component 1 through the liquid locking ability of the liquid absorption component.

[0045] In one embodiment, please continue to refer to Figures 3 to 5 In the extension direction of the atomization channel 14, the first sealing member 20 is sleeved on the end of the bracket 41 facing the liquid storage chamber 31. The first sealing member 20 has an axial sealing portion 21 located between the bracket 41 and the liquid storage chamber 31 and a circumferential sealing portion 24 located between the bracket 41 and the inner side wall of the shell body 11. The bracket 41 is sealed with the shell body 11 through the circumferential sealing portion 24. The bracket 41 and the second sealing member 432 are against each other in the extension direction of the atomization channel 14. The buffer chamber 47 can be formed by the bracket 41, the circumferential sealing portion 24 of the first sealing member 20 and the second sealing member 432. In the embodiment where the size of the circumferential sealing portion 24 in the extension direction of the atomization channel 14 is small, the buffer chamber 47 can also be formed by the bracket 41, the shell body 11 and the second sealing member 432.

[0046] The first cavity wall 4321 of the cache cavity 47 is located on the second sealing member 432, and the second cavity wall 411 is located on the bracket 41; in one embodiment, please refer to Figure 5 The second air channel 412 can be formed by the second cavity wall 411 and the shell body 11 or the circumferential sealing portion 24. Of course, in the embodiment where the second sealing member 432 is not provided in the base 43, and the base 43 is sealed with the shell body 11 through a sealing ring, the bracket 41 and the base body 431 are against each other in the extension direction of the atomization channel 14, and the first cavity wall 4321 can also be provided on the base 43, that is, located on the base body 431.

[0047] In one embodiment, please refer to Figure 4 and Figure 5 The first air channel 4323 of the buffer chamber 47 and the air inlet channel 4313 on the seat body 431 are arranged at intervals in a plane perpendicular to the extension direction of the atomization channel 14 to prevent the atomized liquid entering the air inlet chamber 44 from the buffer chamber 47 from directly flowing out from the air inlet port 4314.

The height direction of the atomizer assembly 1 is in the same direction as the extension direction of the atomizer channel 14. The length direction and the width direction of the atomizer assembly 1 are both perpendicular to the extension direction of the atomizer channel 14. The length direction of the atomizer assembly 1 is perpendicular to the width direction. The size of the atomizer assembly 1 in the length direction is greater than its size in the width direction. The atomizer assembly 1 has one air inlet cavity 44, and two, three, four or more than five buffer cavities 47 can be provided. The number of vents 42 is equal to the number of buffer cavities 47, and the vents 42 and buffer cavities 47 are provided in a one-to-one correspondence. Multiple cache chambers 47 can be arranged around the atomization channel 14 or around the atomization chamber 46. In an embodiment where two cache chambers 47 are provided, the two cache chambers 47 are arranged on both sides of the atomization channel 14 in the length direction of the atomization assembly 1, and the atomization chamber 46 is located between the two cache chambers 47. The atomization chamber 46 is arranged corresponding to the atomization channel 14 in the extension direction of the atomization channel 14. This can increase the air intake into the liquid storage chamber 31, which helps to make the air pressure in the liquid storage chamber 31 uniform.

[0049] In one embodiment, for the vent hole 42, please refer to Figures 3 to 5 The vent hole 42 has a small-diameter hole section 421 and a tapered hole section 422. In the extension direction of the atomization channel 14, the tapered hole section 422 is connected to the side of the small-diameter hole section 421 facing the liquid storage chamber 31. The small-diameter hole section 421 can be a circular hole section, and the hole wall surface of the tapered hole section 422 is a tapered surface. In the extension direction of the atomization channel 14, the diameter of the tapered hole section 422 gradually decreases from the liquid storage chamber 31 to the air inlet 4314. The plugging member 50 includes a spherical ball, the diameter of which is greater than the diameter of the small-diameter hole section 421. The plugging member 50 can be made of rubber material or can also be made of metal material or plastic material. The plugging member 50 is resistant to corrosion by atomized liquid. When the plugging member 50 is in the blocking position, the spherical surface of the plugging member 50 is sealed with the conical surface of the conical hole section 422. When the plugging member 50 is in the connecting position, under the action of the pressure difference between the inside and outside of the liquid storage chamber 31, the plugging member 50 is lifted up, and the spherical surface and the conical surface of the plugging member 50 are arranged at intervals, and external gas can enter the liquid storage chamber 31 along the gap between the conical surface and the spherical surface of the plugging member 50.

[0050] In other embodiments, the blocking member 50 may be in the shape of a capsule, a truncated cone or an ellipsoid, and the outer peripheral surface of the blocking member 50 may be sealed with the conical surface. Of course, the shape of the vent hole 42 is not limited, as long as the aperture of the vent hole 42 can be gradually reduced from the liquid storage chamber 31 to the air inlet 4314 in the extension direction of the atomization channel 14, and the hole wall surface of the vent hole 42 may be an arc surface or a curved surface.

[0051] In one embodiment, please refer to 3 to Figure 5The vent 42 may also have a large-diameter hole section 423, which is connected to the side of the tapered hole section 422 facing the liquid storage chamber 31, the aperture of the large-diameter hole section 423 is larger than the aperture of the tapered hole section 422, and the aperture of the tapered hole section 422 is larger than the aperture of the small-diameter section. When the plugging member 50 is in the connecting position, the plugging member 50 may be located in the large-diameter hole section 423, and a long groove 424 may be provided on the hole side wall of the large-diameter hole section 423, and the long groove 424 is extended in the length direction of the large-diameter hole section 423. When the plugging member 50 is in the connecting position, the air flow may pass through the gap between the wall of the long groove 424 and the plugging member 50, so as to increase the air intake amount and air intake rate from the vent 42 into the liquid storage chamber 31 in the connecting position, thereby ensuring the continuity of the liquid supply to the liquid storage chamber 31.

[0052] In one embodiment, the limiting portion 22 is located on the axial sealing portion 21 of the first sealing member 20; in an embodiment in which the axial sealing portion 21 is not provided on the first sealing member 20, the limiting portion 22 can also be connected to the circumferential sealing portion 24 of the first sealing member 20 through a connecting portion. The limiting portion 22 includes a boss, which is located in the large-diameter hole section 423 of the vent 42, and the size of the boss in the extension direction of the atomization channel 14 is smaller than the size of the large-diameter hole section 423. The boss is a cylindrical structure, and the boss has a through hole 23 that is arranged in the extension direction of the atomization channel 14. The through hole 23 connects the vent 42 with the liquid storage chamber 31, and the radial size of the through hole 23 is smaller than the radial size of the blocking member 50, so that the boss and the blocking member 50 can be held against each other in the extension direction of the atomization channel 14 to limit the blocking member 50 from coming out of the vent 42.

[0053] In other embodiments, the limiting portion 22 can also be located outside the large diameter hole section 423, and the limiting portion 22 extends radially inwardly toward the large diameter hole section 423. The size of the perforation 23 on the limiting portion 22 is smaller than the size of the large diameter hole section 423, and is also smaller than the radial size of the blocking member 50, so as to prevent the blocking member 50 from escaping from the vent 42 under the action of the pressure difference between the inside and outside of the liquid storage chamber 31.

[0054] An embodiment of the present application also provides an atomization device, which includes a power supply component and the atomization component 1 in any of the above embodiments, the power supply component is plug-in-matched with the atomization component 1, and the power supply component is electrically connected to the atomization core in the atomization chamber 46 to realize power supply for the atomization component 1.

[0055] The above specific examples are used to illustrate the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the art, according to the concept of the present invention, some simple deductions, modifications or substitutions can be made.
