Detailed Implementation

[0036] The technical solution of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] In the embodiments described in this application, it should be noted that, unless otherwise stated and limited, the term "connection" should be interpreted broadly. For example, it can be an electrical connection, or a connection between two internal components. It can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above term according to the specific circumstances.

[0038] It should be noted that the terms "first," "second," and "third" used in the embodiments of this application are merely used to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first," "second," and "third" can be interchanged in a specific order or sequence where permitted. It should be understood that the objects distinguished by "first," "second," and "third" can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in an order other than those illustrated or described herein.

[0039] The following combination Figures 1 to 9 The atomizer described in the embodiments of this application will be described in detail.

[0040] The atomizer includes: an atomizing core 400, a housing 110, a mounting base assembly 107, and a conductor 200 having a pressure balancing channel 203. At least a portion of the mounting base assembly 107 is disposed within the housing 110, and the top wall of the mounting base assembly 107 and the inner wall of the housing 110 define a reservoir 101 for storing an aerosol-generating matrix. The aerosol-generating matrix in the reservoir 101 can enter the atomizing core 400, which atomizes the aerosol-generating matrix into vapor for inhalation by the user. The aerosol-generating matrix can be e-liquid, pharmaceutical liquid, etc.

[0041] The atomizing core 400 can be disposed within the outer casing 110. The structure of the atomizing core 400 is not limited, as long as it can atomize the aerosol generation matrix in the liquid storage chamber 101. For example, the atomizing core 400 may include a porous liquid guiding structure. As an example, the atomizing core 400 may include a porous ceramic structure. As yet another example, the atomizing core 400 may include a porous cotton structure.

[0042] The mounting base assembly 107 has a preset puncture site 102; the conductive member 200 is used to puncture the preset puncture site 102; the atomizer's states include: a first state, such as... Figure 1 As shown, the preset puncture site 102 was not punctured; in the second state, as... Figure 2 As shown, the conductive member 200 pierces the preset puncture site 102, and the liquid storage chamber 101 and the air pressure balance channel 203 are connected to achieve air pressure balance in the liquid storage chamber 101, thereby eliminating the problem that the liquid is not easy to flow out due to the low pressure in the liquid storage chamber 101.

[0043] In related technologies, the aerosol generating matrix in the storage chamber is used for atomization. As the aerosol generating matrix in the storage chamber is continuously atomized, a negative pressure is formed in the storage chamber, making it difficult for liquid to exit and affecting the performance of the atomizer. In the second state of the atomizer in this application, the storage chamber 101 and the pressure balance channel 203 are connected. At this time, a negative pressure will not form in the storage chamber 101, and the pressure difference inside and outside the storage chamber 101 is approximately the same, thereby eliminating the problem of difficulty in liquid exit due to low pressure in the storage chamber 101. At the same time, when the atomizer is not in use, in the first state, the preset puncture site 102 is not punctured, and the storage chamber 101 and the pressure balance channel 203 are not connected, which can prevent the aerosol generating matrix in the storage chamber 101 from leaking through the pressure balance channel 203. In one application, during the manufacturing and transportation process, the atomizer can be in a first state, in which the liquid storage chamber 101 and the pressure balance channel 203 are not connected, which can effectively ensure that the atomizer does not leak. During use, the atomizer can be in a second state, in which the liquid storage chamber 101 and the pressure balance channel 203 are connected, ensuring that the liquid storage chamber 101 dispenses liquid normally.

[0044] In this embodiment, the structure of the outer shell 110 is not limited. For example, the outer shell 110 can be a cuboid structure. Or, for example, the outer shell 110 can be a columnar structure. Of course, the outer shell 110 can be an irregular shape.

[0045] In this embodiment, the mounting base assembly 107 may be entirely disposed within the housing 110. Alternatively, the mounting base assembly 107 may be partially disposed within the housing 110.

[0046] In this embodiment, the structure of the conductive element 200 is not limited, as long as the conductive element 200 has a pressure balance channel 203. For example, the conductive element 200 has a first port 201 and a second port 202, and the space within the conductive portion 210 connects the first port 201 and the second port 202 to define the pressure balance channel 203; in the second state, the first port 201 can be connected to the liquid storage chamber 101, and the second port 202 can be connected to the external gas.

[0047] The shape of the pressure balancing channel 203 is not limited. For example, the pressure balancing channel 203 can be a cylindrical cavity, and the diameter of the pressure balancing channel 203 is not limited; as an example, the diameter of the pressure balancing channel 203 can range from 0.1 mm to 1 mm.

[0048] It should be noted that in some embodiments, in the first state, the conductive member 200 is separated from the mounting base assembly 107. When needed, the conductive member 200 can be pierced through the preset piercing part 102.

[0049] In other embodiments, the conductive element 200 is movably disposed on the mounting base assembly 107, that is, the conductive element 200 is connected to the mounting base assembly 107 regardless of whether it is in the first state or the second state, thereby preventing the conductive element 200 from being lost.

[0050] like Figure 1 As shown, in the first state, the conductor 200 can move to a position where the preset puncture site 102 is not punctured, and the liquid storage chamber 101 is not connected to the pressure balance channel 203; as Figure 2 As shown, in the second state, the conductor 200 can be moved to the position where the preset puncture site 102 is punctured. The conductor 200 punctures the preset puncture site 102, and the liquid storage chamber 101 and the pressure balance channel 203 are connected to achieve pressure balance in the liquid storage chamber 101. Pressure balance in the liquid storage chamber 101 can be achieved through the pressure balance channel 203.

[0051] As an example, the mounting base assembly 107 is provided with a mounting channel 104, and the guide member 200 is movably disposed in the mounting channel 104; for example Figure 3 As shown, in the first state, the preset puncture site 102 is not punctured, and the liquid storage chamber 101 is not connected to the pressure balance channel 203; as Figure 4As shown, in the second state, the conductive member 200 pierces the preset puncture portion 102, and the liquid storage chamber 101 and the pressure balance channel 203 are connected to achieve pressure balance in the liquid storage chamber 101. Pressure balance in the liquid storage chamber 101 can be achieved through the pressure balance channel 203. Here, in the first state, the bottom end of the conductive member 200 can protrude from the bottom end of the mounting base assembly 107 so that an external force can be applied to the bottom end of the conductive member 200 to move the conductive member 200. In the second state, the bottom end of the conductive member 200 is accommodated in the mounting channel 104 or flush with the bottom end of the mounting base assembly 107 to facilitate the storage of the conductive member 200 and make the appearance of the atomizer neater.

[0052] The pressure balance channel 203 can be directly connected to the external gas outside the atomizer, or it can be connected to the external gas outside the atomizer through other channels to achieve pressure balance in the liquid storage chamber 101.

[0053] For example, the end of the pressure balancing channel 203 away from the liquid storage chamber 101 can be located outside the housing 110 and communicate with external gas. Alternatively, the end of the pressure balancing channel 203 away from the liquid storage chamber 101 can be located within the space inside the housing 110 that communicates with external gas. As an example, the mounting assembly 107 has an air inlet channel 106, and in the second state, the end of the pressure balancing channel 203 away from the liquid storage chamber 101 is connected to the air inlet channel 106; the housing 110 has an air outlet channel 105, and the air inlet channel 106 and the air outlet channel 105 are respectively connected to the atomizing core 400; the end of the pressure balancing channel 203 away from the liquid storage chamber 101 can be directly connected to the air inlet channel 106, or it can be connected to the air inlet channel 106 through other spaces.

[0054] The power source for the movement of the conductive element 200 is not limited. For example, the conductive element 200 can be connected to a driving element, which can drive the conductive element 200 to move. The driving element can be a motor. Of course, the power source for the conductive element 200 can also be an external force. The conductive element 200 can move under the action of the external force, and when the external force is removed, the relative positional relationship between the conductive element 200 and the mounting base assembly 107 is fixed. The external force can be applied directly to the conductive element 200 or transmitted to the conductive element 200 through other structures. As an example, the atomizer may also include: an operating element, which is movably disposed in the housing 110. A first end of the operating element is connected to the conductive element 200, and a second end of the operating element protrudes outside the housing 110 so that an external force applied to the second end of the operating element can drive the conductive element 200 to move through the operating element.

[0055] In some alternative implementations, such as Figure 3 and Figure 4As shown, the mounting base assembly 107 may include a first support member 120 and a first seal member 300. The first support member 120 has a first through hole 103. The first seal member 300 is disposed in the first through hole 103 and seals the first through hole 103. The guide member 200 is used to pierce the first seal member 300 so as to form a predetermined piercing portion 102 through at least a portion of the first seal member 300.

[0056] In this implementation, the first support member 120 can be a relatively rigid structure to provide support. For example, the first support member 120 can be a plastic structure.

[0057] In this implementation, the structure of the first sealing element 300 is not limited, as long as it can seal the first through hole 103 and prevent the aerosol-generating matrix from flowing through it. For example, the first sealing element 300 can be an elastic element, capable of deformation, so that at least a portion of the first sealing element 300 is filled into the first through hole 103 through deformation, thereby reliably sealing the first through hole 103; at the same time, the deformable first sealing element 300 is also easily punctured. As an example, the first sealing element 300 can be a rubber structure. As another example, the first sealing element 300 can be a silicone structure. The first sealing element 300 can be partially or completely disposed within the first through hole 103.

[0058] The first seal 300 can wrap around the outside of the conductor 200 to prevent leakage during the movement of the conductor 200 relative to the first seal 300, such as... Figure 3 and Figure 4 As shown. Figure 3 As shown, in the first state, the first port 201 is located inside the first seal 300. At this time, the first port 201 is blocked by the first seal 300, and the second port 202 is connected to the air intake channel 106. Because the first port 201 is blocked by the first seal 300, the pressure balance channel 203 does not connect the liquid storage chamber 101 and the air intake channel 106. The liquid storage chamber 101 and the air intake channel 106 are not connected, thus preventing the aerosol generation matrix in the liquid storage chamber 101 from leaking into the air intake channel 106 through the pressure balance channel 203. Figure 4 As shown, in the second state, at least a portion of the first port 201 is located outside the first seal 300 and communicates with the liquid storage chamber 101, and the second port 202 is communicated with the air inlet channel 106. The liquid storage chamber 101 and the air inlet channel 106 are connected through the air pressure balance channel 203. At this time, the pressure of the liquid storage chamber 101 and the air inlet channel 106 is approximately the same, and the pressure difference inside and outside the liquid storage chamber 101 is approximately the same, thereby eliminating the problem that the liquid is not easy to flow out due to the low pressure of the liquid storage chamber 101.

[0059] Of course, the first seal 300 may not be wrapped around the outside of the conductor 200. In the first state, the first seal 300 may be located at one end of the conductor 200.

[0060] In other implementations of this application, the mounting bracket assembly 107 may include only the first support member 120, without the first sealing member 300. In this case, the conductive member 200 can directly pierce a portion of the first support member 120, forming a preset piercing portion 102. Figure 1 and Figure 2 As shown.

[0061] In this implementation, such as Figure 3 and Figure 4 As shown, the outer casing 110 may have an exhaust pipe 111, and the space inside the exhaust pipe 111 is an exhaust channel 105. The mounting base assembly 107 may include a sleeve portion 123 protruding from the top wall of the first support member 120. The top end of the sleeve portion 123 and the bottom end of the exhaust pipe 111 are connected to define a hollow region. The sleeve portion 123 is provided with a liquid inlet 122 communicating with the liquid storage chamber 101. The atomizing core 400 is disposed in the hollow region and is used to heat and atomize the aerosol generating matrix from the liquid inlet 122. The aerosol generating matrix in the liquid storage chamber 101 can enter the atomizing core 400 through the liquid inlet 122. The atomizing core 400 atomizes the aerosol generating matrix into atomized vapor, which can flow out from the exhaust channel 105.

[0062] The axial direction of the liquid inlet 122 can be approximately perpendicular to the long axis of the housing 110. In other embodiments, the liquid inlet 122 can also be in other shapes or directions, such as the axial direction of the liquid inlet 122 being parallel to or at a certain angle to the long axis of the housing 110.

[0063] In this implementation, the atomizer may further include: a second seal 500; the second seal 500 surrounds the periphery of the first support 120, and the second seal 500 seals against the inner wall of the housing 110, thereby preventing the atomized liquid in the liquid storage chamber 101 from leaking from the periphery of the first support 120.

[0064] The structure of the second seal 500 is not limited. For example, the second seal 500 can be an O-ring. The number of second seals 500 is not limited. For example, such as... Figure 3 and Figure 4 As shown, the atomizer may include: two second seals 500.

[0065] In this implementation, a conductive component 600 may also be provided at the bottom of the atomizing core 400. The conductive component 600 is used to transmit external power to the atomizing core 400 for its use.

[0066] In this implementation, the mounting bracket assembly 107 may further include: a second support member 130; the second support member 130 is disposed on one side of the housing 110, and a first space is formed between the second support member 130 and the first support member 120; an air intake channel 106 is disposed on the second support member 130 and the first support member 120, and the second port 202 of the conductor 200 is connected to the air intake channel 106 through the first space.

[0067] In some optional implementations of this application, the mounting base assembly 107 is provided with a mounting channel 104, and the guide member 200 is movably disposed in the mounting channel 104; the guide member 200 may include: a base portion 220 and a guide portion 210 disposed on the top side of the base portion 220; the base portion 220 is engaged in the mounting channel 104, the guide portion 210 has the air pressure balance channel 203, and the top end of the guide portion 210 is a pointed tip for piercing the preset piercing portion 102; so that the preset piercing portion 102 can be quickly pierced through the top end of the guide portion 210; at the same time, by the base portion 220 being engaged in the mounting channel 104, the guide member 200 and the outer shell 110 can be more firmly fixed, preventing the guide member 200 from moving relative to the outer shell 110 even without external force.

[0068] Of course, in other implementations of this application, the top end of the conductive part 210 may also be a planar end.

[0069] In this implementation, the structure of the base 220 is not limited. For example, the base 220 can be a columnar structure. Or, for example... Figure 3 and Figure 4 The seat 220 can also be a stepped axis.

[0070] The method by which the seat 220 is engaged with the mounting channel 104 is not limited. For example, the seat 220 has an elastic protrusion, and the seat 220 can be engaged with the mounting channel 104 by engaging the elastic protrusion with a groove in the wall of the mounting channel 104. Here, the wall of the mounting channel 104 can be provided with at least two grooves, and the elastic protrusion is engaged with one of the at least two grooves. In the first state of the atomizer, the elastic protrusion is engaged with the other of the at least two grooves. In the second state of the atomizer, under the action of external force, the elastic protrusion can be disengaged from the at least two grooves, so that the conductor 200 can move.

[0071] Of course, the seat 220 and the mounting channel 104 can be interference-fitted, and the seat 220 can be engaged within the mounting channel 104 by friction; the amount of interference between the seat 220 and the mounting channel 104 is not limited. For example, the range of the interference between the seat 220 and the mounting channel 104 can be from 0.05mm to 0.2mm.

[0072] In this implementation, the structure of the conductive part 210 is not limited. For example, the conductive part 210 can be a columnar structure.

[0073] The method of connecting the guide portion 210 and the seat portion 220 is not limited. For example, the guide portion 210 and the seat portion 220 can be connected by in-mold injection molding. Another example is that the guide portion 210 and the seat portion 220 can be connected by interference fitting. Yet another example is that the guide portion 210 and the seat portion 220 can be connected by snap-fit. Alternatively, the guide portion 210 and the seat portion 220 can also be integrally molded.

[0074] The location of the first port 201 and the second port 202 is not limited.

[0075] For example, the conductive part 210 is a hollow tube, with a first port 201 on its top surface and a second port 202 on its bottom circumferential sidewall. Figure 6 and Figure 7 As shown.

[0076] When both the guide portion 210 and the seat portion 220 are columnar structures, the diameter of the guide portion 210 is smaller than the diameter of the seat portion 220, so that it can be stably locked in the mounting channel 104 through the seat portion 220 with a larger diameter, and communicate with the liquid storage chamber 101 through the air pressure balance channel 203 of the guide portion 210 with a smaller diameter.

[0077] The number of second ports 202 is not limited. For example, there can be multiple second ports 202, spaced apart, to increase the connected area of ​​the pressure balance channel 203; simultaneously, with the total area of ​​the second ports 202 being the same, at least two second ports 202 can reduce the area of ​​a single second port 202, preventing a large area of ​​the second port 202 from affecting the strength of the conductor 200. As an example, such as... Figure 8 and Figure 9 As shown, when the second port 202 is provided in the conductive part 210, the conductive part 210 can be provided with three second ports 202.

[0078] like Figure 3 and Figure 5As shown, in the first state, the bottom end of the seat 220 can protrude from the surface of the mounting bracket 107, so that an external force can be applied to the seat 220 through the bottom end of the seat 220; as Figure 4 As shown, in the second state, the bottom end of the seat 220 can be flush with the bottom end of the mounting bracket 107 to make the atomizer look neat, and the seat 220 does not affect the connection between the atomizer and other structural components.

[0079] The atomizer of this application embodiment includes: a housing 110, a mounting base assembly 107 at least partially disposed within the housing 110, the top wall of the mounting base assembly 107 and the inner wall of the housing 110 defining a liquid storage chamber 101 for storing an aerosol generation matrix, the mounting base assembly 107 having a preset puncture portion 102; a conductor 200 having a pressure balance channel 203, the conductor 200 being used to puncture the preset puncture portion 102; the atomizer has the following states: a first state, the preset puncture portion 102 is not punctured; a second state, the conductor 200 punctures the preset puncture portion 102, the liquid storage chamber 101 and the pressure balance channel 203 are connected to achieve pressure balance in the liquid storage chamber 101, thereby eliminating the problem of difficulty in liquid dispensing due to low pressure in the liquid storage chamber 101.

[0080] This application also describes an atomizing device, including the atomizer described in this application and a power supply component, wherein the power supply component is used to supply power to the atomizer.

[0081] The power supply component can supply power to the atomizer core through the conductive component 600.

[0082] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
