Description

Technical Field

[0001] This application relates to the field of aerosol generating devices, and particularly to a liquid storage component, an atomizer, and an aerosol generating device. Background Technology

[0002] Common aerosol generating devices include an atomizer and a power supply unit, with the atomizer connected to the power supply unit. During operation, the power supply unit supplies power to the atomizer.

[0003] The atomizer comprises a liquid reservoir and an atomizing component, with the atomizing component located within the liquid reservoir, which contains the aerosol matrix. To prevent aerosol matrix leakage during transportation and storage before the atomizer is put into use, some related technologies have two liquid chambers within the liquid reservoir, connected by an inlet. Before the atomizer is put into use, the inlet is sealed with a plug, and the aerosol matrix is ​​stored in one of the chambers, preventing absorption by the atomizing component. Upon commissioning, the portion of the plug extending outside the liquid reservoir is pushed inward, separating it from the inlet and connecting the two chambers. The aerosol matrix then flows into the other chamber and is absorbed by the atomizing component.

[0004] It has been found that after the sealing component separates from the liquid inlet, the gap between the sealing component and the liquid inlet is small, which hinders the flow of the aerosol matrix and affects the entry of the aerosol matrix into another liquid chamber. Summary of the Invention

[0005] This application provides a liquid storage component, an atomizer, and an aerosol generating device, enabling the aerosol matrix to flow more smoothly from one liquid tank to another after the atomizer is put into use. The technical solution is as follows: In a first aspect, embodiments of this application provide a liquid storage assembly, which includes a housing, a liquid inlet switch, and an atomizing component mounting base. The housing includes a cylindrical body and a partition. The atomizing component mounting base is connected to one end of the cylindrical body and is sealed to the cylindrical body. The partition is located inside the cylindrical body and is spaced apart from the atomizing component mounting base. The circumferential edge of the partition is connected to the inner wall of the cylindrical body. The partition divides the interior of the cylindrical body into a first liquid chamber and a second liquid chamber. The second liquid chamber is located between the partition and the atomizing component mounting base. The partition has a liquid inlet hole that connects the first liquid chamber and the second liquid chamber. The liquid inlet switch includes a sealing part and an extension part. The sealing part is movably inserted into the liquid inlet hole. One end of the extension part is connected to the sealing part, and the other end of the extension part extends to the side of the atomizing component mounting base away from the partition. The extension part is used to drive the sealing part to move away from the first liquid tank to disengage from the liquid inlet hole.

[0006] In some examples, the atomizing component mounting base also has a liquid inlet switch socket, which is opposite to the liquid inlet hole; the sealing part is inserted into the liquid inlet switch socket, forming a movable seal with the liquid inlet switch socket, and is movable along the length direction of the liquid inlet switch socket; the end of the extension away from the sealing part extends out relative to the liquid inlet switch socket.

[0007] In some examples, the outer periphery of the sealing part has a first sealing rib and a second sealing rib; when the liquid inlet switch closes the liquid inlet hole, the sealing part is located in the liquid inlet hole and the liquid inlet switch socket, the first sealing rib is sealed to the liquid inlet hole, and the second sealing rib is sealed to the liquid inlet switch socket; when the liquid inlet hole is open, the sealing part is located in the liquid inlet switch socket, and the first sealing rib and the second sealing rib are respectively sealed to the liquid inlet switch socket.

[0008] In some examples, the liquid storage assembly further includes a stop located on the side of the atomizing assembly mounting base away from the partition, the stop being slidably connected to the atomizing assembly mounting base and capable of sliding to a first position or a second position relative to the atomizing assembly mounting base; If the sealing part is in the liquid inlet hole and the stop member is in the first position, at least a portion of the stop member is opposite to the end face of the extension away from the sealing part, so as to restrict the liquid inlet switch from moving out of the liquid inlet hole; If the stop is in the second position, the end face of the extension away from the sealing portion is offset from the stop.

[0009] In some examples, the atomizing component mounting base has an air intake channel with an inlet located on the side of the atomizing component mounting base away from the partition and an outlet located on the side of the atomizing component mounting base closer to the partition, the outlet being used to communicate with the atomizing component mounted on the atomizing component mounting base; If the stop is in the first position, the stop closes the entrance; If the stop is in the second position, the inlet is open.

[0010] In some examples, the extension has a clearance hole that, when the sealing portion is outside the inlet hole, is opposite to the stop to accommodate at least a portion of the stop when the stop moves to the first position.

[0011] In some examples, the stop has multiple air inlets, which are opposite to the inlet when the stop is in the second position.

[0012] In some examples, the liquid storage assembly further includes an elastic element connected to the liquid inlet switch and the atomizing assembly mounting base, respectively, for providing a force that causes the liquid inlet switch to move outward from the liquid inlet orifice.

[0013] Secondly, embodiments of this application also provide an atomizer, the atomizer comprising: The liquid storage assembly as described in the first aspect is used to store an aerosol matrix; An atomizing component, at least a portion of which is located in the second liquid chamber, is connected to an atomizing component mounting base, and is used to heat an aerosol matrix to form an aerosol.

[0014] Thirdly, embodiments of this application also provide an aerosol generating device, the aerosol generating device including a power supply component and an atomizer as described in the second aspect, the power supply component being used to supply power to the atomizer component.

[0015] The beneficial effects of the technical solutions provided in this application include at least the following: A partition is installed within the shell's cylindrical body, separating a first liquid chamber and a second liquid chamber within the cavity formed by the cylindrical body and the atomizing component mounting base. The first liquid chamber is used to store the aerosol matrix. The partition has a liquid inlet hole, which can be sealed by a liquid inlet switch to prevent the aerosol matrix from entering the second liquid chamber and being absorbed by the atomizing component before the atomizer is put into use. The sealing part of the liquid inlet switch is movably inserted into the liquid inlet hole, sealing it. One end of the extension of the liquid inlet switch is connected to the sealing part, while the other end extends to the side of the atomizing component mounting base away from the partition. The extension can move the sealing part away from the first liquid chamber, disengaging it from the liquid inlet hole, thus opening the liquid inlet hole. Because the liquid inlet switch is entirely outside the liquid inlet hole after the sealing part disengages, it does not occupy any space in the inlet hole, allowing the aerosol matrix to flow more smoothly from the first liquid chamber into the second liquid chamber.

[0025] Figure 1 This is a schematic diagram of the structure of an aerosol generating device provided in an embodiment of this application, as shown below. Figure 1 As shown, the aerosol generating device includes a power supply component 1 and an atomizer 2. The power supply component 1 is used to supply power to the atomizer 2.

[0026] Figure 1 The structure shown is only an illustration, and the relative positions of the power supply component 1 and the atomizer 2 are not limited to this. Figure 1 The power supply component 1 shown is located at the end of the atomizer 2. For example, the power supply component 1 can also be located on the side of the atomizer 2.

[0027] Figure 2 This is a simplified structural diagram of an atomizer provided in an embodiment of this application, as shown below. Figure 2 As shown, the atomizer 2 includes a liquid storage assembly 21, an atomizing assembly 22, and a nozzle 23. The liquid storage assembly 21 is used to store the aerosol matrix. The atomizing assembly 22 is located in the liquid storage assembly 21 and is used to absorb and heat the aerosol matrix.

[0028] The liquid storage assembly 21 may include a housing 211 and an atomizing assembly mounting base 212. The atomizing assembly mounting base 212 is sealed to the housing 211 to form a liquid storage chamber. A separator 213 is provided in the liquid storage chamber, dividing it into a first liquid chamber A and a second liquid chamber B. To prevent the aerosol matrix in the first liquid chamber A from leaking into the second liquid chamber B before the atomizer 2 is put into use, a sealing ring 2131 is provided between the separator 213 and the inner wall of the housing 211. A liquid inlet C is provided on the separator 213. Before the atomizer 2 is put into use, the liquid inlet C is closed, and the aerosol matrix is ​​stored in the first liquid chamber A. When the atomizer 2 is put into use, the liquid inlet C is opened, allowing the aerosol matrix to flow into the second liquid chamber B and be absorbed by the atomizing assembly 22.

[0029] The inlet port C is sealed by a plug 210, a portion of which is located within the inlet port C and the other portion extends to the outside of the liquid storage assembly 21. When using the atomizer 2, the plug 210 can be pushed inward to separate it from the inlet port C, allowing the aerosol matrix to flow into the second liquid chamber B.

[0030] However, since part of the sealing component 210 is located in the liquid inlet C, the aerosol matrix can only flow into the second liquid chamber B through the gap between the sealing component 210 and the liquid inlet C, resulting in poor flow of the aerosol matrix.

[0031] In order to enable the aerosol matrix to flow more smoothly into the second liquid tank B, this application provides a liquid storage component.

[0032] Figure 3 This is an exploded structural diagram of a liquid storage component provided in an embodiment of this application, as shown below. Figure 3 As shown, the liquid storage assembly 21 includes a housing 211, a liquid inlet switch 214, and an atomizing assembly mounting base 212.

[0033] Figure 4 This is a schematic diagram of the structure of a shell provided in an embodiment of this application, such as... Figure 4 As shown, the shell 211 includes a cylindrical body 31 and a partition 32. The cylindrical body 31 and the partition 32 are integrally formed, that is, the cylindrical body 31 and the partition 32 can be formed as a whole by integral molding technology, such as by injection molding.

[0034] The atomizing component mounting base 212 is connected to one end of the cylinder 31 and is sealed to the cylinder 31. The partition 32 is located inside the cylinder 31 and is arranged at intervals with the atomizing component mounting base 212.

[0035] The circumferential edge of the partition 32 is connected to the inner wall of the cylinder 31, dividing the interior of the cylinder 31 into a first liquid chamber A and a second liquid chamber B. The second liquid chamber B is located between the partition 32 and the atomizing component mounting base 212. The partition 32 has a liquid inlet C and an atomizing component insertion hole D. The liquid inlet C connects the first liquid chamber A and the second liquid chamber B, and the liquid inlet switch 214 is used to close the liquid inlet C. The atomizing component mounting base 212 is used to install the atomizing component 22 inserted into the atomizing component insertion hole D.

[0036] Since the edge of the partition 32 is connected to the inner wall of the cylinder 31, and the partition 32 and the cylinder 31 are integrally formed, there is no need to set a sealing ring between the partition 32 and the inner wall of the cylinder 31 for sealing. This can prevent the aerosol matrix from entering the second liquid chamber B in advance due to sealing failure, thereby reducing the risk of aerosol matrix leakage before the atomizer 2 is put into use.

[0037] like Figure 4 As shown, the partition 32 has a rounded corner 32b on the side near the first liquid tank A. The rounded corner 32b is located at the connection between the partition 32 and the inner wall of the cylinder 31.

[0038] In the first liquid chamber A, the edge of the partition 32 is provided with rounded corners 32b, which is beneficial for demolding when the shell 211 is made by injection molding, and also facilitates the discharge of aerosol matrix from the first liquid chamber A when the atomizer 2 is used, thus avoiding waste caused by aerosol matrix remaining at the edge of the partition 32.

[0039] like Figure 4 As shown, the partition 32 has a sealing groove 32a on the side near the atomizing component mounting base 212, and the atomizing component insertion hole D is located at the bottom of the sealing groove 32a.

[0040] The atomizing assembly also includes a first seal 33, which is located in the sealing groove 32a and surrounds the atomizing assembly socket D. The first seal 33 is used to seal and cooperate with the atomizing assembly 22.

[0041] In the atomizer 2, the atomizing component 22 is disposed through the partition 32. One end of the atomizing component 22 is connected to the atomizing component mounting base 212, and the other end of the atomizing component 22 is connected to the mouthpiece 23. By setting the atomizing component insertion hole D at the bottom of the sealing groove 32a, and setting the first sealing element 33 in the sealing groove 32a to form a seal with the atomizing component 22, the sealing performance between the atomizing component 22 and the partition 32 can be improved, preventing the aerosol matrix of the first liquid chamber A from leaking into the second liquid chamber B through the gap between the atomizing component 22 and the partition 32.

[0042] Figure 5 This is a schematic diagram of the internal structure of a liquid storage component provided in an embodiment of this application, as shown below. Figure 5As shown, the liquid inlet switch 214 may include a sealing portion 2141 and an extension portion 2142. The sealing portion 2141 is movably inserted into the liquid inlet port C. One end of the extension portion 2142 is connected to the sealing portion 2141, and the other end of the extension portion 2142 extends to the side of the atomizing assembly mounting base 212 away from the partition plate 32. The extension portion 2142 is used to move the sealing portion 2141 away from the first liquid chamber A to disengage from the liquid inlet port C. By disengaging the sealing portion 2141 from the liquid inlet port C, the aerosol matrix in the first liquid chamber A can enter the second liquid chamber B through the liquid inlet port C.

[0043] A partition 32 is provided in the cylinder 31 of the housing 211 to separate a first liquid chamber A and a second liquid chamber B in the cavity formed by the cylinder 31 and the atomizing component mounting base 212. The first liquid chamber A can be used to store the aerosol matrix. The partition 32 has a liquid inlet hole C, which can be closed by a liquid inlet switch 214 to prevent the aerosol matrix from entering the second liquid chamber B through the liquid inlet hole C and being absorbed by the atomizing component 22 before the atomizer 2 is put into use. The sealing part 2141 of the liquid inlet switch 214 is movably inserted into the liquid inlet hole C and can close the liquid inlet hole C. One end of the extension part 2142 of the liquid inlet switch 214 is connected to the sealing part 2141, and the other end extends to the side of the atomizing component mounting base 212 away from the partition. The extension part 2142 can drive the sealing part 2141 to move away from the first liquid chamber A to disengage from the liquid inlet hole C, thereby opening the liquid inlet hole C. Since the sealing part 2141 is separated from the liquid inlet hole C, the liquid inlet switch 214 is located outside the liquid inlet hole C and will not occupy part of the space of the liquid inlet hole C, so that the aerosol matrix can enter the second liquid chamber B more smoothly from the first liquid chamber A.

[0044] The liquid inlet switch 214 can form a sliding seal with the atomizing component mounting base 212, so that the liquid inlet switch 214 can move relative to the atomizing component mounting base 212, while preventing the aerosol matrix from leaking between the liquid inlet switch 214 and the atomizing component mounting base 212.

[0045] like Figure 5 As shown, the atomizing assembly mounting base 212 may also have a liquid inlet switch socket 41a, which is opposite to the liquid inlet hole C. A sealing portion 2141 is inserted into the liquid inlet switch socket 41a, forming a movable seal with the liquid inlet switch socket 41a, and is movable along the length of the liquid inlet switch socket 41a. One end of the extension portion 2142, away from the sealing portion 2141, extends out relative to the liquid inlet switch socket 41a.

[0046] By providing an inlet switch socket 41a opposite to the inlet hole C in the atomizing component mounting base 212, and using the sealing part 2141 to form a seal with the inlet hole C and the inlet switch socket 41a respectively, it is beneficial to simplify the structure and reduce the cost of the atomizer 2.

[0047] like Figure 5 As shown, the outer periphery of the sealing part 2141 may have a first sealing rib 21411 and a second sealing rib 21412. When the liquid inlet switch 214 closes the liquid inlet hole C, the sealing part 2141 is located in the liquid inlet hole C and the liquid inlet switch socket 41a. The first sealing rib 21411 is sealed with the liquid inlet hole C, and the second sealing rib 21412 is sealed with the liquid inlet switch socket 41a.

[0048] Figure 6 This is a schematic diagram of the internal structure of a liquid storage component provided in an embodiment of this application, as shown below. Figure 6 As shown, when the liquid inlet hole C is open, the sealing part 2141 is located in the liquid inlet switch socket 41a, and the first sealing rib 21411 and the second sealing rib 21412 are respectively sealed and fitted with the liquid inlet switch socket 41a.

[0049] Before the liquid inlet C is opened, the aerosol matrix is ​​stored in the first liquid chamber A. The liquid inlet C is sealed by the first sealing rib 21411, and there is almost no risk of leakage at the liquid inlet switch socket 41a. After the liquid inlet C is opened, both the first sealing rib 21411 and the second sealing rib 21412 are located in the liquid inlet switch socket 41a, sealing the liquid inlet switch socket 41a and improving the sealing performance at the liquid inlet switch socket 41a, which can reduce the risk of leakage during the use of the atomizer 2. After the first sealing rib 21411 is removed from the liquid inlet C, it is not left idle, but is used to seal the liquid inlet switch socket 41a, which helps to reduce the number of sealing structures required.

[0050] Figure 7 This is a schematic diagram of the structure of a liquid storage component provided in an embodiment of this application, as shown below. Figure 7 As shown, the liquid storage assembly also includes a stop 34, which is located on the side of the atomizing assembly mounting base 212 away from the partition 32. Figure 8 This is a schematic diagram of the structure of a liquid storage component provided in an embodiment of this application, as shown below. Figure 7 and Figure 8 As shown, the stop 34 is slidably connected to the atomizing component mounting base 212, and the stop 34 can slide relative to the atomizing component mounting base 212 to a first position (i.e., Figure 7 (as shown in the image) or the second position (i.e.) Figure 8 (The location shown).

[0051] Reference Figure 7 As shown, if the sealing part 2141 is in the liquid inlet hole C and the stop member 34 is in the first position, at least a portion of the stop member 34 is opposite to the end face of the extension 2142 away from the sealing part 2141, so as to restrict the liquid inlet switch 214 from moving out of the liquid inlet hole C.

[0052] Reference Figure 8As shown, if the stop 34 is in the second position, the end face of the extension 2142 away from the sealing part 2141 is offset from the stop 34.

[0053] Before the atomizer 2 is put into use, the sealing part 2141 is in the liquid inlet C, sealing the liquid inlet C. In this state, the stop member 34 is adjusted to the first position, blocking at least a portion of the stop member 34 at the end face of the extension 2142 away from the sealing part 2141, so that the sealing part 2141 cannot be removed from the liquid inlet C.

[0054] When the atomizer 2 is put into use, the stop 34 can be adjusted to the second position, and the liquid inlet switch 214 loses the stopping function of the stop 34, so that the liquid inlet switch 214 can move out of the liquid inlet hole C, and the sealing part 2141 can be disengaged from the liquid inlet hole C.

[0055] The stopper 34 is designed to prevent the liquid inlet switch 214 from moving due to vibration or other reasons during transportation, and to prevent the sealing part 2141 from disengaging from the liquid inlet hole C, thereby increasing the risk of aerosol matrix leakage.

[0056] In this embodiment, the end face of the extension 2142 away from the sealing portion 2141 is offset from the stop 34. This means that the extension 2142 and the stop 34 are offset from each other in the direction of movement of the extension 2142, and also means that the stop 34 is located outside the movement path of the extension 2142. The movement path of the extension 2142 is the range swept through space during the movement of the extension 2142. If the stop 34 is in the movement path of the extension 2142, the movement of the extension 2142 will be obstructed. If the stop 34 is outside the movement path of the extension 2142, the stop 34 will not affect the movement of the extension 2142.

[0057] As an example, the stop 34 may include a main body 341 and a stop 342, with the main body 341 slidably connected to the side of the atomizing assembly mounting base 212 away from the partition 32. The stop 342 is connected to one side of the main body 341.

[0058] The direction of movement of the stop member 34 can intersect with the direction of movement of the liquid inlet switch 214. For example, the direction of movement of the stop member 34 is perpendicular to the direction of movement of the liquid inlet switch 214.

[0059] like Figure 6 As shown, the atomizing component mounting base 212 may have an air intake channel 212a. The air intake channel 212a has an inlet 212b and an outlet 212c. The inlet 212b of the air intake channel 212a is located on the side of the atomizing component mounting base 212 away from the partition 32, and the outlet 212c of the air intake channel 212a is located on the side of the atomizing component mounting base 212 closer to the partition 32. The outlet 212c is used to communicate with the atomizing component 22.

[0060] During the use of the aerosol generating device, when suction is performed through the nozzle 23, the airflow enters the air intake channel 212a from the inlet 212b and exits the air intake channel 212a from the outlet 212c, entering the atomizing component 22. In other words, the inlet 212b is the opening through which the airflow enters the air intake channel 212a during suction, and the outlet 212c is the opening through which the airflow exits the air intake channel 212a during suction.

[0061] If the stop 34 is in the first position, the stop 34 closes the inlet 212b. If the stop 34 is in the second position, the inlet 212b is open.

[0062] Before the atomizer 2 is put into use, and when the atomizer 2 is in use but idle, the stop 34 can be placed in the first position to close the air intake channel 212a. This helps to balance the pressure inside the housing 211 and prevents the aerosol matrix inside the housing 211 from leaking into the air intake channel 212a and then leaking out of the atomizer 2 through the outlet 212c. During the use of the atomizer 2, the stop 34 can be placed in the second position to open the inlet 212b, allowing airflow to smoothly enter the air intake channel 212a.

[0063] In this embodiment, the stop member 34 serves both as a stop for the liquid inlet switch 214 and as a control for the opening and closing of the inlet 212b. This eliminates the need for additional components to control the opening and closing of the inlet 212b, which helps reduce the number of components, makes the structure of the atomizer 2 more compact, and helps reduce costs.

[0064] As an example, such as Figure 7 As shown, the stop member 34 may have multiple air inlets 341a. When the stop member 34 is in the second position, the multiple air inlets 341a are opposite to the inlet 212b.

[0065] When the stop member 34 is in the second position, the inlet 212b is open, and air can enter the inlet 212b of the intake passage 212a through the multiple air inlets 341a. However, when the stop member 34 is in the first position, the multiple air inlets 341a are not aligned with the inlet 212b, causing the inlet 212b to be closed.

[0066] Figure 9 This is a schematic diagram of the structure of a liquid storage component provided in an embodiment of this application, as shown below. Figure 9 As shown, the extension 2142 also has a clearance hole 2142a. If the sealing part 2141 is outside the liquid inlet C, the clearance hole 2142a is opposite to the stop member 34, so that when the stop member 34 moves to the first position (i.e. Figure 9 When in the position shown, at least a portion of the stop 34 is accommodated.

[0067] After the atomizer 2 is put into use, the sealing part 2141 has disengaged from the liquid inlet C. To prevent the liquid inlet switch 214 from obstructing the movement of the stop member 34, a clearance hole 2142a is provided on the extension 2142 of the liquid inlet switch 214 to avoid the stop member 34. After the sealing part 2141 disengages from the liquid inlet C, the clearance hole 2142a is directly opposite the stop part 342 of the stop member 34. When the stop member 34 moves from the second position to the first position, the stop part 342 can extend into the clearance hole 2142a without being blocked by the liquid inlet switch 214, so that the stop member 34 can still control the opening and closing of the inlet 212b.

[0068] Figure 10 This is a schematic diagram of the structure of an elastic element provided in an embodiment of this application, such as... Figure 10 As shown, the liquid storage assembly may further include an elastic element 2123. The elastic element 2123 is connected to the liquid inlet switch 214 and the atomizing assembly mounting base 212, respectively. The elastic element 2123 is used to provide a force that causes the liquid inlet switch 214 to move outward from the liquid inlet port C.

[0069] Before the atomizer 2 is put into use, the stop 34 is in the first position, and the liquid inlet switch 214 is resisted by the stop 34 under the elastic force of the elastic member 2123. When the atomizer 2 is put into use, the user only needs to put the stop 34 in the second position, so that the liquid inlet switch 214 loses the stopping effect of the stop 34 and moves outward of the liquid inlet C under the elastic force of the elastic member 2123, opening the liquid inlet C. In addition, when the user puts the stop 34 in the second position, the inlet 212b of the air intake channel 212a is also opened. The liquid inlet C and the inlet of the air intake channel 212a are opened with only one operation, which is convenient for the user. After the liquid inlet C is opened, the elastic force of the elastic member 2123 can also maintain the position of the liquid inlet switch 214, preventing the liquid inlet switch 214 from re-entering the liquid inlet C and closing the liquid inlet C due to external impact or other factors during the use of the atomizer 2.

[0070] In some examples, two elastic elements 2123 can be provided. The two elastic elements 2123 can be arranged on both sides of the extension 2142 respectively. Compared with one elastic element 2123, two elastic elements 2123 can not only provide greater elastic force, but also have a more symmetrical force on the extension 2142. This can make the movement of the liquid inlet switch 214 more stable and avoid the liquid inlet switch 214 tilting due to unbalanced force, which would affect the movement of the liquid inlet switch 214.

[0071] As an example, first hooks 2121 can be provided on both sides of the extension 2142, and two second hooks 2122 can be provided on the atomizing component mounting base 212, with the two second hooks 2122 located on both sides of the extension 2142 respectively. An elastic member 2123 can be connected between the first hooks 2121 and the second hooks 2122 located on the same side of the extension 2142.

[0072] For example, the elastic element 2123 may include a spring, such as a tension spring, the two ends of which are convenient to be connected to the first hook 2121 and the second hook 2122.

[0073] In some other possible implementations, the elastic element 2123 may also include at least one of a spring sheet or an elastic rope.

[0074] Figure 11 This is an exploded structural diagram of an atomizing component mounting base provided in an embodiment of this application, as shown below. Figure 11 As shown, the atomizing component mounting base 212 may include a sealing seat 41, a base 42, and a bracket 43. The sealing seat 41 is connected to the cylinder 31. A portion of the sealing seat 41 can be inserted into the cylinder 31 and seal against the inner wall of the cylinder 31.

[0075] Reference Figure 5 The sealing seat 41 may have an atomizing component slot 41b on the side near the partition 32, which is opposite to the atomizing component insertion hole D on the partition 32. The liquid inlet switch insertion hole 41a is located on one side of the atomizing component slot 41b and is opposite to the liquid inlet hole C on the partition 32.

[0076] The sealing seat 41 may have a protrusion 411 on the side away from the partition 32. The protrusion 411 may be provided corresponding to the atomizing component slot 41b. The atomizing component slot 41b may extend into the protrusion 411. The liquid inlet switch socket 41a is located on one side of the protrusion 411.

[0077] The base 42 can be connected to the end of the protrusion 411 away from the partition 32. The aforementioned second hook 2122 can be provided on the outer wall of the base 42 on the side near the liquid inlet switch socket 41a.

[0078] like Figure 11 As shown, a guide groove 42b can also be provided on the outer wall of the base 42 near the liquid inlet switch socket 41a. The guide groove 42b extends along the movement direction of the liquid inlet switch 214.

[0079] Reference Figure 7As shown, a guide protrusion 21421 can also be provided on the side wall of the extension 2142. The guide protrusion 21421 can be inserted into the guide groove 42b and can slide with the guide groove 42b to limit the movement direction of the liquid inlet switch 214 and make the movement of the liquid inlet switch 214 more stable.

[0080] The bracket 43 can be fitted over the base 42. The bracket 43 can be connected to the base 42 and the sealing seat 41 respectively, so that the sealing seat 41, the base 42 and the bracket 43 are connected into a whole.

[0081] For example, the bracket 43 can be connected to the outer wall of the base 42 via a first snap 421, and the bracket 43 can be connected to the outer wall of the sealing seat 41 via a second snap 412.

[0082] The stop 34 can be slidably connected to the side of the bracket 43 away from the base 42.

[0083] The atomizing component mounting base 212 may also include a second seal 44, which may be located at the end of the protrusion 411 away from the partition 32. The end face of the protrusion 411 away from the partition 32 may have a first groove 411a, in which the second seal 44 is located. The second seal 44 may seal against the inner wall of the first groove 411a to reduce leakage through the air intake channel 212a.

[0084] The atomizing assembly mounting base 212 may also include a liquid suction member 45, which is located in the cavity formed by the protrusion 411 and the base 42. The liquid suction member 45 is located on the side of the second seal 44 away from the protrusion 411. The liquid suction member 45 is used to absorb and store any liquid that may be generated at the second seal 44, preventing liquid from leaking outside the atomizer 2 or onto electrical structures such as the circuit board 47, which could affect the normal operation of the electrical structures.

[0085] For example, the absorbent element 45 may include absorbent cotton.

[0086] like Figure 11 As shown, the atomizing component mounting base 212 may also include an air inlet 46, which may be located on the side of the base 42 away from the sealing seat 41, and may be clamped between the base 42 and the bracket 43. The inlet 212b of the air intake channel 212a may be formed on the air inlet 46.

[0087] A second groove 42a may be provided on the side of the base 42 away from the sealing seat 41. The air inlet 46 may be located in the second groove 42a and sealed with the inner wall of the second groove 42a to improve air tightness.

[0088] A gap may also be left between the side of the base 42 away from the sealing seat 41 and the bracket 43, which can be used to accommodate the circuit board 47.

[0089] The air intake channel 212a can pass through the sealing seat 41, the second seal 44, the liquid suction element 45, the base 42, the air intake nozzle 46 and the bracket 43.

[0090] This application also provides an atomizer. Figure 12 This is a schematic diagram of the structure of an atomizer provided in an embodiment of this application, as shown below. Figure 12 As shown, the atomizer 2 may include an atomizing component 22 and any of the aforementioned liquid storage components 21. The liquid storage component 21 is used to store the aerosol matrix. The atomizing component 22 is inserted into the atomizing component socket D and is connected to the atomizing component mounting base 212. The atomizing component 22 is used to heat the aerosol matrix to form an aerosol.

[0091] As an example, the atomizing assembly 22 forms an atomizing channel 22a. The mouthpiece 23 is connected to one end of the atomizing channel 22a. The atomizing assembly 22 includes a tubular support 221, a liquid guide 222, a heating element 223, and a pin 224. The liquid guide 222 and the heating element 223 are located in the tubular support 221. The pin 224 is electrically connected to the heating element 223.

[0092] The tubular support 221 provides space inside the housing 211 to accommodate the liquid guiding component 222 and the heating component 223. The tubular support 221 may have structures such as holes and slits on its wall to allow the aerosol matrix in the second liquid chamber B to enter the atomization channel 22a and be absorbed by the liquid guiding component 222. The heating component 223 is used to heat the aerosol matrix in the liquid guiding component 222, causing the aerosol matrix to vaporize.

[0093] The material and structure of the heating element 223 are not limited, as long as it can generate heat. For example, the heating element 223 may include at least one of heating mesh, heating film, heating wire, and heating plate.

[0094] like Figure 12 As shown, the atomizer 2 may also include a circuit board 47, which may be located in the gap between the base 42 on the side away from the sealing seat 41 and the bracket 43.

[0095] This application also provides an aerosol generating apparatus. Figure 13 This is a schematic diagram of the structure of an aerosol generating device provided in an embodiment of this application, as shown below. Figure 13 As shown, the aerosol generating device includes a power supply component 1 and the aforementioned atomizer 2. The power supply component 1 is used to supply power to the atomizer component 22.

[0096] The power supply component 1 may include a battery 11, specifically a lithium-ion battery, a nickel-metal hydride battery, a nickel-cadmium battery, or a lithium-based battery. The lithium-based battery may include a lithium cobalt battery, a lithium iron phosphate battery, a lithium titanate battery, or a lithium polymer battery.

[0097] like Figure 13 As shown, the aerosol generating device may also include a housing 3, with the power supply component 1 and the atomizer 2 both located within the housing 3. Figure 13 To facilitate the demonstration of the structure, at least a portion of the outer shell 3 has been removed.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
