The shell is provided with a liquid storage cavity which is open on one side along a first direction. The mounting piece cooperates with the shell along the first direction. The mounting piece is provided with a mounting cavity which is open on one side along the first direction and communicates with the liquid storage cavity. The wall surface of the mounting cavity is provided with a first through hole and a second through hole. The atomizing core cover is arranged on the side of the first through hole away from the mounting cavity. The liquid storage piece is mounted into the mounting cavity through the second through hole.

Description

Technical Field

[0001] This application relates to the field of atomization technology, specifically to an atomizer and an aerosol generating device. Background Technology

[0002] Aerosol generating devices atomize an aerosol generating matrix and mix it with air to form an aerosol. The aerosol can then be inhaled by the user.

[0003] The atomizer includes a housing, a liquid reservoir, and an atomizing core. At least a portion of the liquid reservoir and at least a portion of the atomizing core are located inside the housing. The liquid reservoir can absorb the aerosol generating matrix and is in fluid communication with the atomizing core to deliver the aerosol generating matrix to the atomizing core. At the same time, it reduces the risk of dry burning and other problems caused by the atomizing core not being able to directly contact the aerosol generating matrix due to changes in the atomizer's orientation.

[0004] In related technologies, during the assembly of the atomizer, the liquid storage component is easily squeezed or damaged by rubbing against the housing, which does not affect the liquid storage component's ability to absorb aerosol-generating matrix or its ability to deliver aerosol-generating matrix to the atomizing core. Utility Model Content

[0005] In view of this, the embodiments of this application aim to provide an atomizer and aerosol generating device that helps reduce the probability of the liquid storage component rubbing against other parts during the assembly process.

[0006] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0007] This application provides an atomizer, including:

[0008] Atomizer coil;

[0009] The shell has a liquid storage chamber, which is open on one side along a first direction;

[0010] The mounting component mates with the housing along the first direction. The mounting component has a mounting cavity, which is open on one side along the first direction and communicates with the liquid storage cavity. The wall of the mounting cavity has a through first hole and a through second hole. The atomizing core cover is located on the side of the first hole away from the mounting cavity. The through direction of the second hole intersects with the first direction.

[0011] A liquid reservoir, at least a portion of which is installed into the mounting cavity through the second through hole, wherein at least a portion of the liquid reservoir is located within the mounting cavity and in contact with the atomizing core, and wherein the liquid reservoir does not protrude from the mounting component along the through direction of the second through hole when in contact with the atomizing core.

[0012] In some embodiments, the mounting cavity is located between the first through hole and the second through hole along a second direction, the first direction intersects the second direction, and the penetration direction of the first through hole and the penetration direction of the second through hole are both along the second direction.

[0013] In some embodiments, the atomizer further includes a seal that covers the side of the second through hole opposite to the mounting cavity along a second direction, the second direction intersecting the first direction.

[0014] In some embodiments, a portion of the housing is located on the side of the seal opposite to the second through-hole.

[0015] In some embodiments, the seal includes a sealing space, which is open on one side along the first direction to form an inlet and outlet for the mounting member to enter and exit, and has a connecting hole on the other side. At least a portion of the mounting member is located in the sealing space and fits against the wall of the sealing space. The connecting hole connects the mounting cavity and the liquid storage cavity.

[0016] In some embodiments, a portion of the wall of the sealed space protrudes along a second direction to form a sealing protrusion, at least a portion of which is embedded in the second through-hole along the second direction and fits against the liquid reservoir.

[0017] In some embodiments, the outer surface of the seal is provided with a plurality of first sealing ribs, which are arranged along the first direction. In a projection plane perpendicular to the second direction, the projection of the second through hole toward the opening of the seal along the second direction is located between the projections of the two first sealing ribs along the second direction.

[0018] In some embodiments, the seal is provided with a second sealing rib on its outer surface along the second direction, and the two ends of the second sealing rib along its extension direction are connected to the first sealing rib. In a projection plane perpendicular to the second direction, the projection of a portion of the first sealing rib along the second direction and the projection of the second sealing rib along the second direction together surround the projection of the second through hole toward the opening of the seal along the second direction.

[0019] In some embodiments, the outer surface of the liquid storage component includes a first surface and a second surface, the first surface being in contact with the atomizing core, the second surface facing the portion of the sealing component that covers the second through hole, and the area of ​​the second surface being not less than the area of ​​the first surface.

[0020] This application also provides an aerosol generating device, which includes a power supply component and an atomizer as described in any of the foregoing embodiments, wherein the power supply component is electrically connected to the atomizer.

[0021] The atomizer in this embodiment uses a second through hole to install the liquid storage component. This makes it difficult for other parts in the atomizer to apply force to the liquid storage component along the first direction during the assembly process. This reduces the risk that the liquid storage component may be squeezed or damaged due to force, which could prevent it from properly delivering the aerosol matrix to the atomizing core. It also reduces the risk that the liquid storage component may become dislodged from the atomizing core due to force displacement. This reduces the probability of quality problems occurring during the atomizer assembly process and ensures that the liquid storage component functions properly during subsequent user use.

[0039] This application provides an atomizer, see the following embodiment. Figures 1 to 5 The atomizer includes an atomizing core 10, a housing 20, a mounting component 30, and a liquid reservoir 40.

[0040] The housing 20 is provided with a liquid storage chamber 20a, which is open on one side along the first direction.

[0041] Mounting component 30 mates with housing 20 along a first direction. Mounting component 30 is provided with mounting cavity 30a. Mounting cavity 30a is open on one side along the first direction and communicates with liquid storage cavity 20a. The wall of mounting cavity 30a is provided with a through first through hole 30b and a through second through hole 30c. Atomizing core 10 is covered on the side of the first through hole 30b away from mounting cavity 30a. The through direction of the second through hole 30c intersects with the first direction.

[0042] At least a portion of the liquid storage component 40 is installed into the mounting cavity 30a through the second through hole 30c. At least a portion of the liquid storage component 40 is located in the mounting cavity 30a and is in contact with the atomizing core 10. When the liquid storage component 40 is in contact with the atomizing core 10, the liquid storage component 40 does not protrude from the mounting component 30 along the through direction of the second through hole 30c.

[0043] The storage chamber 20a is used to store the aerosol generation matrix. The aerosol generation matrix is ​​a fluid medium.

[0044] The mounting cavity 30a is connected to the liquid storage cavity 20a so that the aerosol generation matrix can flow into the mounting cavity 30a.

[0045] The mounting cavity 30a can be fluidly connected to the atomizing core 10 through the first through hole 30b.

[0046] The portion of the liquid reservoir 40 located within the mounting cavity 30a can absorb aerosols within the mounting cavity 30a to generate a matrix. The inner wall of the mounting cavity 30a helps to constrain the position of the liquid reservoir 40, ensuring that the liquid reservoir 40 remains in fluid communication with the atomizing core 10.

[0047] The first through hole 30b enables fluid communication between the liquid storage component 40 and the atomizing core 10, thereby allowing the aerosol generation matrix absorbed in the liquid storage component 40 to be transported to the atomizing core 10, so that the atomizing core 10 can atomize the aerosol generation matrix by means of heating or other methods.

[0048] During the assembly of the atomizer, at least part of the liquid storage component 40 is inserted into the preset position in the mounting cavity 30a through the second through hole 30c, so that the liquid storage component 40 contacts the atomizing core 10 through the first through hole 30b and the liquid storage component 40 does not protrude from the mounting component 30 along the through direction of the second through hole 30c. Then, the mounting component 30 and the housing 20 are fitted together along the first direction.

[0049] When the liquid reservoir 40 is in contact with the atomizing core 10, the liquid reservoir 40 does not protrude from the mounting member 30 along the through-hole 30c. In other words, after the liquid reservoir 40 is installed in the preset position, it will not protrude through the second through-hole 30c to the outer surface of the mounting member 30. Thus, during the process of fitting the mounting member 30 and the housing 20 along the first direction, it is difficult for the housing 20 and other components in the atomizer to rub against the liquid reservoir 40 along the first direction.

[0050] When the liquid storage component 40 is in contact with the atomizing core 10, the liquid storage component 40 does not protrude from the mounting component 30. Alternatively, a portion of the surface of the liquid storage component 40 may be flush with the surface of the mounting component 30; or a portion of the liquid storage component 40 may pass through the second through hole 30c without protruding from the opening edge of the second through hole 30c on the side away from the mounting cavity 30a; or the liquid storage component 40 may not enter the second through hole 30c.

[0051] In this embodiment of the atomizer, the liquid storage component 40 is installed using a second through hole 30c. This makes it difficult for other parts in the atomizer to exert force on the liquid storage component 40 along the first direction during the assembly process. This reduces the risk that the liquid storage component 40 may be squeezed or damaged due to force, which could prevent it from properly delivering the aerosol matrix to the atomizing core 10. It also reduces the risk that the liquid storage component 40 may become dislodged from the atomizing core 10 due to force displacement. This reduces the probability of quality problems occurring during the atomizer assembly process and ensures that the liquid storage component 40 functions properly during subsequent user use.

[0052] The liquid reservoir 40 has pores that may or may not be visible to the naked eye. At least some of the pores are interconnected, so that the liquid reservoir 40 can absorb the aerosol generation matrix through capillary action and the aerosol generation matrix can pass through the pores to contact the atomizing core 10.

[0053] The specific material of the liquid storage component 40 can be cotton, sponge, etc.

[0054] In some embodiments, see Figure 4 The atomizer also includes a sealing ring 60, which is sandwiched between the atomizing core 10 and the mounting part 30, and the sealing ring 60 is arranged around the opening edge of the first through hole 30b.

[0055] Thus, the sealing effect of the sealing ring 60 reduces the risk of leakage of the aerosol generation matrix in the mounting cavity 30a through the gap between the atomizing core 10 and the mounting component 30.

[0056] In some embodiments, see Figure 4 The penetration direction of the first through hole 30b intersects with the first direction.

[0057] In some embodiments, see Figure 4 A portion of the liquid storage component 40 is located inside at least one of the first through hole 30b and the second through hole 30c, such that the wall surface of at least one of the first through hole 30b and the second through hole 30c can limit the liquid storage component 40 in the first direction.

[0058] In some embodiments, see Figure 3 and Figure 4 The mounting cavity 30a is located between the first through hole 30b and the second through hole 30c along the second direction. The first direction intersects the second direction, and the penetration direction of the first through hole 30b and the penetration direction of the second through hole 30c are both along the second direction.

[0059] During the installation of the liquid storage component 40, after the liquid storage component 40 is inserted into the second through hole 30c along the second direction, the liquid storage component 40 can directly contact the atomizing core 10 along the second direction.

[0060] In this way, the atomizing core 10 directly limits the installation of the liquid storage component 40, thus simplifying the installation process.

[0061] Understandably, after the liquid reservoir 40 comes into contact with the atomizing core 10 in the second direction, the liquid reservoir 40 cannot move further toward the atomizing core 10 in the second direction, and the liquid reservoir 40 reaches the preset installation position.

[0062] In some embodiments, the first direction is perpendicular to the second direction.

[0063] When the user is standing or sitting while using the atomizer, the first direction is roughly along the direction of gravity, and the second direction is roughly along the horizontal.

[0064] In some embodiments, see Figure 3 and Figure 4 At least a portion of the mounting member 30 is embedded into the liquid storage cavity 20a along the first direction. The wall of the liquid storage cavity 20a provides constraint to the mounting member 30 in a direction perpendicular to the first direction, thereby achieving a fit between the mounting member 30 and the housing 20 along the first direction.

[0065] In some embodiments, see Figure 4 and Figure 6 The atomizer also includes a seal 50, which covers the side of the second through hole 30c away from the mounting cavity 30a along the second direction, and the first direction intersects the second direction.

[0066] Thus, the sealing effect of the sealing element 50 reduces the probability of the aerosol generation matrix in the mounting cavity 30a leaking out of the atomizer through the second through hole 30c, thereby improving the sealing performance of the atomizer.

[0067] The seal 50 is made of an elastic material to improve its sealing performance through elastic deformation. The specific material of the seal 50 is not limited, and can include, for example, rubber or silicone.

[0068] In some embodiments, see Figure 4 A portion of the housing 20 is located on the side of the seal 50 opposite to the second through hole 30c.

[0069] Thus, by having at least a portion of the seal 50 sandwiched between the housing 20 and the mounting 30, the sealing effect is improved, and the risk of aerosol generation matrix in the second through hole 30c leaking from the gap between the seal 50 and the mounting 30 is reduced.

[0070] Understandably, the relative position between the seal 50 and the mounting part 30 needs to be kept fixed in order to maintain the sealing effect of the seal 50 on the second through hole 30c.

[0071] The specific method for fixing the relative position between the seal 50 and the mounting part 30 is not limited.

[0072] For example, see Figure 4 and Figure 7 The sealing element 50 includes a sealing space 50a, which is open on one side along a first direction to form an inlet and outlet for the mounting element 30 to enter and exit, and has a connecting hole 50b on the other side. At least a portion of the mounting element 30 is located in the sealing space 50a and fits against the wall of the sealing space 50a. The connecting hole 50b connects the mounting cavity 30a and the liquid storage cavity 20a.

[0073] At least a portion of the mounting component 30 can be inserted into the sealed space 50a along the first direction via the inlet and outlet. Then, the mounting component 30 and the sealing component 50 can continue to be inserted into the liquid storage chamber 20a along the first direction. In this way, the assembly method of always using the first direction is beneficial to simplify the assembly steps and improve the assembly efficiency of the atomizer.

[0074] By forming a sealed space 50a, the seal 50 can cover part of the outer surface of the mounting component 30, thereby improving the sealing effect between the mounting component 30 and the housing 20 and reducing the probability of leakage of the aerosol generation matrix.

[0075] The aerosol-generating matrix in the liquid storage chamber 20a can enter the mounting chamber 30a through the connecting hole 50b.

[0076] Understandably, the second through hole 30c is located on one side of the mounting cavity 30a along the second direction. A portion of the wall surface of the sealing space 50a along the second direction can directly cover the second through hole 30c during the process of the mounting member 30 entering the sealing space 50a.

[0077] The first sealing part 51 forms one side wall of the sealing space 50a along the second direction and the outer side surface of the sealing member 50 along the second direction.

[0078] In some embodiments, the connecting hole 50b extends along a first direction so that the aerosol generating matrix can directly pass through the connecting hole 50b into the mounting cavity 30a along the first direction, thereby improving the efficiency of replenishing the aerosol generating matrix into the mounting cavity 30a.

[0079] In some embodiments, the mounting member 30 is completely located within the sealed space 50a, and the sealing member 50 is completely located within the liquid storage cavity 20a. This further improves the sealing effect between the inner wall of the liquid storage cavity 20a and the mounting member 30.

[0080] It is understandable that the mounting component 30, the sealing component 50, and the atomizing core 10 are all located entirely within the liquid storage chamber 20a so that the housing 20 can protect the three components.

[0081] In some embodiments, see Figure 5 The edges of the opening 30aa of the mounting cavity 30a are flush with each other along the first direction. In other words, the structure of the opening 30aa of the mounting member 30 surrounding the mounting cavity 30a has the same height along the first direction, so that the mounting member 30 can be easily inserted into the sealed space 50a along the first direction.

[0082] Understandably, in the direction perpendicular to the first direction, the inner wall of the sealed space 50a fits against the mounting component 30.

[0083] In some embodiments, see Figure 4 and Figure 7 A portion of the wall surface of the sealed space 50a protrudes along the second direction to form a sealing protrusion 511, at least a portion of the sealing protrusion 511 being embedded in the second through hole 30c along the second direction.

[0084] Thus, on the one hand, the sealing protrusion 511 can stop and cooperate with the liquid storage component 40 in the second direction, which helps to limit the movement of the liquid storage component 40 in the second direction, reduce the shaking of the liquid storage component 40 during the use of the atomizer, and improve the user experience; on the other hand, the sealing protrusion 511 can stop and cooperate with the inner wall of the second through hole 30c in the first direction, which helps to fix the mounting component 30 and the sealing component 50 relative to each other in the first direction.

[0085] In some embodiments, see Figure 4 The sealing protrusion 511 fits against the liquid storage component 40, so that the liquid storage component 40 is sandwiched between the atomizing core 10 and the sealing protrusion 511 along the second direction, thereby fixing the liquid storage component 40.

[0086] It is understood that the sealing protrusion 511 can generate elastic deformation in the second direction so that during the process of the mounting member 30 being inserted into the sealing space 50a in the first direction, the sealing protrusion 511 can retract in the second direction to avoid the structure of the mounting member 30, and after reaching the position of the second through hole 30c, it can extend in the second direction to embed into the second through hole 30c.

[0087] In some embodiments, see Figure 6 The outer surface of the seal 50 is provided with a plurality of first sealing ribs 52, which are arranged along a first direction. The first sealing ribs 52 are annular structures surrounding the first direction.

[0088] Thus, the first sealing rib 52 helps to improve the sealing performance and can further prevent the aerosol matrix from leaking from the seal 50.

[0089] Each of the first sealing ribs 52 can be connected to each other along the first direction, or they can be spaced apart from each other along the first direction.

[0090] The first sealing rib 52 is sandwiched between the inner wall of the liquid storage cavity 20a and the sealing element 50 to improve the sealing effect.

[0091] In some embodiments, see Figure 4 and Figure 6 In the projection plane perpendicular to the second direction, the projection of the second through hole 30c toward the opening of the seal 50 along the second direction is located between the projections of the two first sealing ribs 52 along the second direction.

[0092] The first sealing rib 52 fits more tightly against the inner wall of the liquid storage chamber 20a. Even if the aerosol generating matrix leaks from the second through hole 30c of the sealing element 50 due to damage or other reasons, the space between the two first sealing ribs 52 can still constrain the flow of the aerosol generating matrix, thus improving the atomizer's ability to suppress leakage.

[0093] In some embodiments, see Figure 6 The area of ​​the sealing element 50 covering the second through hole 30c is located on one side of a first sealing rib 52 along the first direction, and at least one first sealing rib 52 is located on the other side of the first sealing rib 52. This helps to further reduce the probability of leakage of aerosol generation matrix and improve the sealing effect.

[0094] In some embodiments, see Figure 6 The sealing member 50 is provided with a second sealing rib 53 on its outer surface along the second direction. The two ends of the second sealing rib 53 along its extension direction are connected to the first sealing rib 52. In the projection plane perpendicular to the second direction, the projection of the portion of the first sealing rib 52 along the second direction and the projection of the second sealing rib 53 along the second direction together surround the projection of the second through hole 30c toward the opening of the sealing member 50 along the second direction.

[0095] Thus, on the one hand, suppressing the deformation of the first sealing part 51 in the second direction can better ensure that the first sealing part 51 fits the liquid storage component 40 along the second direction; on the other hand, it can further reduce the space that the aerosol generation matrix can flow after leaking from the first sealing part 51, thereby further improving the sealing effect.

[0096] The second sealing rib 53 is sandwiched between the inner wall of the liquid storage cavity 20a and the sealing element 50 to improve the sealing effect.

[0097] It is understood that the second sealing rib 53 is located between two first sealing ribs 52 spaced apart from each other along the first direction, and is connected to one of the first sealing ribs 52.

[0098] In some embodiments, see Figure 6 The connection position between the second sealing rib 53 and the first sealing rib 52 is located on the side of the second sealing rib 53 away from the open position of the sealing space 50a along the first direction.

[0099] This helps to reduce the deformation of the second sealing rib 53 in the first direction due to the friction between it and the inner wall of the liquid storage cavity 20a during the process of installing the sealing member 50 into the liquid storage cavity 20a, and helps the second sealing rib 53 maintain its sealing effect.

[0100] In some embodiments, see Figure 6There are multiple second sealing ribs 53, and each second sealing rib 53 is arranged in a direction away from the first sealing part 51 to further improve the sealing effect.

[0101] In some embodiments, the seal 50 is an integral structure, which simplifies the assembly steps of the atomizer.

[0102] In some embodiments, see Figure 4 The outer surface of the liquid storage component 40 includes a first surface 40a and a second surface 40b. The first surface 40a is in contact with the atomizing core 10, and the second surface 40b faces the portion of the sealing component 50 that covers the second through hole 30c. The area of ​​the second surface 40b is not less than the area of ​​the first surface 40a.

[0103] This helps to make the force between the liquid storage component 40 and the first sealing part 51 more uniform, reducing the probability of problems such as distortion and deformation of the liquid storage component 40 due to the force of the first sealing part 51, and the contact area with the atomizing core 10 not meeting the design requirements.

[0104] In some embodiments, see Figure 4 The dimension of the first through hole 30b along the first direction is smaller than the dimension of the second through hole 30c along the first direction. The liquid storage component 40 includes a first part 41 and a second part 42 arranged along the second direction. A first surface 40a is provided on the first part 41 and a second surface 40b is provided on the second part 42. The dimension of the first part 41 along the first direction is smaller than the dimension of the second part 42 along the first direction.

[0105] See Figure 4 The dimension of the first part 41 along the first direction is L1, and the dimension of the second part 42 along the first direction is L2, where L1 < L2.

[0106] This allows operators to visually determine whether to insert the first part 41 of the liquid storage component 40 into the mounting cavity 30a through the second through hole 30c during the assembly of the atomizer, reducing the probability of incorrect installation and improving assembly efficiency.

[0107] This application also provides an aerosol generating device, which includes a power supply component and an atomizer as described in any of the foregoing embodiments, wherein the power supply component is electrically connected to the atomizer.

[0108] Thus, by adopting the atomizer in the embodiments of this application, the risk of assembly quality problems during the assembly of the aerosol generating device is reduced, and the liquid storage component 40 can function normally during the user's use of the aerosol generating device.

[0109] The power supply component can provide electrical energy to the atomizing core 10, so that the atomizing core 10 can atomize the aerosol generation matrix by means of heating or other methods.
