Description

Technical Field

[0001] This application relates to the field of electronic atomization device technology, and in particular to a power supply component and an electronic atomization device. Background Technology

[0002] An electronic atomizing device is an electronic product that generates aerosols for users to inhale, using an atomizing aerosol generating matrix. It generally has a battery component, an atomizing component, and a housing component. The battery component and the atomizing component are both housed in the housing component. The battery component provides power to the atomizing component so that the atomizing component can generate aerosols when the user inhales.

[0003] In the process of developing this application, the inventors discovered that: Currently, in order to improve safety, it is necessary to set up a battery pressure relief channel in the electronic atomizing device. In existing electronic atomizing devices, the battery pressure relief channel is sealed, and it only opens to release pressure when the battery sprays high-pressure liquid or gas. However, the electronic atomizing device needs to maintain airflow between the inside and outside during operation. To ensure the waterproof performance of the electronic atomizing device, a waterproof and breathable membrane needs to be set at the air vent or a separate adhesive application process needs to be used. However, whether a waterproof membrane is set or a separate adhesive application is used, it will increase the corresponding assembly process and material costs, affecting the competitiveness of the electronic atomizing device in the market.

[0043] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0044] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0045] Existing electronic atomizing devices generally use microphone activation, which relies on air pressure difference. Therefore, a microphone port is required in the electronic atomizing device to ensure the normal operation of the microphone activation function. In addition, electronic atomizing devices contain power supply components. To improve the power supply component and to achieve waterproofing, existing electronic atomizing devices use waterproof and breathable membranes or adhesives to ensure waterproofing. However, both waterproof and breathable membranes and adhesives require additional materials and assembly processes, thus increasing the manufacturing cost of electronic atomizing devices and affecting their market competitiveness.

[0046] This application provides a power supply assembly 100; please refer to [link / reference]. Figure 1 and Figure 2 The power supply assembly 100 includes a housing assembly 1 and a support 2. The housing assembly 1 is provided with a microchannel 11 and an air port (including but not limited to being achieved by means of gaps or openings) to communicate with the outside. The support 2 is disposed in the housing assembly 1 and defines a battery compartment 21 for accommodating the battery 6. The microchannel 11 extends non-linearly to form a tortuous fluid path. The battery compartment 21 communicates with the air port through the microchannel 11, thereby maintaining a normal communication state with the outside.

[0047] The above structure allows the housing 1a to communicate with the external environment through the microchannel 11 and the air port. When the electronic atomizing device has an airflow sensor, the airflow sensor can communicate with the external environment through the microchannel 11 and the air port, thereby enabling the airflow sensor to work normally.

[0048] The tortuous fluid paths formed by the microchannels 11 can prevent external liquids from entering the housing assembly 1 through the microchannels 11, thereby improving the waterproof capability of the power assembly 100. Furthermore, the fluid paths in the microchannels 11 include capillary paths, or the width of the narrowest fluid path in the microchannels 11 is less than or equal to 0.5 mm. The waterproof capability of the microchannels 11 at least meets the IPX4 waterproof rating.

[0049] The battery compartment 21 is connected to the air vent through the microchannel 11, which allows the battery compartment 21 to release pressure through the microchannel 11, thereby helping to improve the safety of the battery 6 assembly.

[0050] In some embodiments, the battery compartment 21 has an open opening 211 to facilitate the removal and replacement of the battery 6.

[0051] In some embodiments, please refer to Figure 1 and Figure 3 The housing assembly 1 includes a housing 1a and a cover 1b that is at least partially disposed inside the housing 1a and supports the bracket 2. At least a portion of the microchannel 11 is disposed between the cover 1b and the housing 1a.

[0052] In some embodiments, the housing 1a is provided with a receiving cavity 1a1, and the cover 1b and the bracket 2 are both received in the receiving cavity 1a1. The cover 1b and the bracket 2 may occupy only a part of the receiving cavity 1a1, and the other part of the receiving cavity 1a1 is configured to accommodate external components, wherein the aforementioned external components refer to devices that require electricity, such as atomizing components.

[0053] In some embodiments, please refer to Figure 2 The housing 1a is provided with a vent 1b11, which is located at the connection between the bracket 2 and the external device, so that the air in the housing cavity 1a1 can be discharged in time when the external component is housed in the housing cavity 1a1.

[0054] The connection methods between the cover 1b and the housing 1a include, but are not limited to, screw connection, snap connection, adhesive connection, and interference fit. For example, in this embodiment, please refer to... Figure 1 and Figure 3 The cover 1b and the housing 1a are connected by a screw connection. Specifically, the power supply assembly 100 includes a screw connector 3. The cover 1b is provided with a screw hole 1b1, and the housing 1a is provided with a first through hole 1a2. The screw connector 3 passes through the first through hole 1a2 and is screwed into the screw hole 1b1, thereby connecting the cover 1b and the housing 1a by screw connection.

[0055] Understandably, the microchannel 11 can be formed by either the cover 1b or the housing 1a, or by both of them. For example, the microchannel 11 can be disposed on the inner surface of the housing 1a or on the outer surface of the cover 1b; or the microchannel 11 can be defined by both the cover 1b and the housing 1a. For example, a part of the microchannel 11 can be disposed on the cover 1b, and another part of the microchannel 11 can be disposed on the housing 1a. When the housing 1a and the cover 1b are connected, they together form the microchannel 11.

[0056] It should be noted that when the microchannel 11 can be jointly defined by the cover 1b and the housing 1a, the cover 1b can define the boundary of the microchannel 11, while the main body of the microchannel 11 is disposed on the housing 1a; or the housing 1a can define the boundary of the microchannel 11, while the main body of the microchannel 11 is disposed on the cover 1b. For example, in this application, the main body of the microchannel 11 is disposed on the cover 1b, and the housing 1a defines the boundary of the microchannel 11. This allows for easy replacement of the cover 1b when the microchannel 11 is damaged, thus improving the convenience of maintaining the power supply assembly 100.

[0057] For details, please refer to Figure 3 The cover 1b includes a sidewall 1b2 connected to the bracket 2; a guide groove 1b21 is provided on the outer surface of the sidewall 1b2, and at least a portion of the microchannel 11 is disposed in the guide groove 1b21. The maximum width of the guide groove 1b21 can be less than or equal to 1.5 mm, preferably less than or equal to 1 mm. The minimum width of the guide groove 1b21 can be less than or equal to 1 mm, preferably less than or equal to 0.5 mm. The guide groove 1b21 can have a relatively constant width. At least two points in the guide groove 1b21 can have different widths.

[0058] In order to improve the ability of the flow channel 1b21 to impede external liquids, in some embodiments, a flow-blocking structure 1b23 for restricting the flow of fluid is provided in the flow channel 1b21.

[0059] For details, please refer to Figure 4The flow channel 1b21 includes a first sidewall 1b211 and a second sidewall 1b212 disposed opposite to each other, the first sidewall 1b211 and the second sidewall 1b212 defining the boundary of the flow channel 1b21; the flow obstruction structure 1b23 includes a first baffle 1b231 and a second baffle 1b232, the first baffle 1b231 is connected to the first sidewall 1b211 and extends toward the second sidewall 1b212, a first gap 111 is provided between the second sidewall 1b212 and the first baffle 1b231, the first gap 111 allows fluid to pass through, the second baffle 1b232 is connected to the second sidewall 1b212 and extends toward the first sidewall 1b211, a second gap 112 is provided between the second baffle 1b232 and the first sidewall 1b211, the second gap 112 allows fluid to pass through, the first gap 111 and the second gap 112 constitute part of the microchannel 11. The width of the first gap 111 and / or the second gap 112 may be less than or equal to 0.5 mm.

[0060] It should be noted that the connection between the first baffle wall 1b231 and the first side wall 1b211 is optional, not mandatory. In other embodiments, a gap allowing gas flow may also exist between the first baffle wall 1b231 and the first side wall 1b211. Similarly, the connection between the second baffle wall 1b232 and the second side wall 1b212 is optional, not mandatory. In other embodiments, a gap allowing gas flow may also exist between the second baffle wall 1b232 and the second side wall 1b212. Having both the first baffle wall 1b231 and the second baffle wall 1b232 is optional, not mandatory.

[0061] Understandably, the orientation of the first baffle 1b231 and the second baffle 1b232 is optional: vertically, including at least one of the first baffle 1b231 and the second baffle 1b232 being perpendicular to the first sidewall 1b211 and the second sidewall 1b212; or inclined, including at least one of the first baffle 1b231 and the second baffle 1b232 being inclined to the first sidewall 1b211 and the second sidewall 1b212.

[0062] For example, in this embodiment, the first baffle 1b231 and the second baffle 1b232 are arranged in an inclined relationship with the first sidewall 1b211 and the second sidewall 1b212. The first baffle 1b231 is inclinedly disposed on the first sidewall 1b211, and the second baffle 1b232 is inclinedly disposed on the second sidewall 1b212; or, the first baffle 1b231 and the second baffle 1b232 both extend inclinedly toward the air inlet in the guide groove 1b21, and their extension directions are intersecting.

[0063] It should be noted that on the same side of the air inlet, the inclination direction of the first baffle 1b231 and the second baffle 1b232 is opposite to the fluid flow direction of the guide channel 1b21, so that the first baffle 1b231 and the second baffle 1b232 can effectively obstruct the fluid flowing in the guide channel 1b21.

[0064] Regarding the first baffle 1b231 and the second baffle 1b232 mentioned above, please refer to 4. The first baffle 1b231 includes a first inclined surface 1b2311 and a first straight surface 1b2312. A first arc transition surface 1b2313 is provided at the connection between the first inclined surface 1b2311 and the first straight surface 1b2312. And / or, the second baffle 1b232 includes a second inclined surface 1b2321 and a second straight surface 1b2322. A second arc transition surface 1b2323 is provided at the connection between the second inclined surface 1b2321 and the second straight surface 1b2322. The presence of the first arc transition surface 1b2313 and the second arc transition surface 1b2323 reduces the turbulence generated by the fluid flowing through the guide channel 1b21, thereby reducing the disturbance of air between the inclined surface and the straight surface when the airflow flows in the guide channel 1b21, and ensuring smooth airflow in the intake channel.

[0065] It is understandable that there are multiple first baffles 1b231 and second baffles 1b232, and there is at least one second baffle 1b232 between any two adjacent first baffles 1b231, so that the first baffles 1b231 and the second baffles 1b232 form an alternating staggered arrangement in the flow guide channel 1b21, further optimizing the obstruction effect of the first baffles 1b231 and the second baffles 1b232 on the fluid.

[0066] It should be noted that the specific number of the first baffle 1b231 and the second baffle 1b232 is selected according to the actual length of the guide channel 1b21, and will not be illustrated here.

[0067] In some embodiments, please refer to Figure 5 The cover 1b is provided with a connecting hole 1b3, which is configured to connect the battery compartment 21 and the microchannel 11 to ensure that the microchannel 11 can relieve pressure on the battery compartment 21.

[0068] For further details, please refer to Figure 6 and Figure 7The cover 1b includes a first groove wall 1b4 and a second groove wall 1b5 disposed opposite to each other. Both the first groove wall 1b4 and the second groove wall 1b5 define part of the boundary of the microchannel 11. A connecting hole 1b3 is formed on the first groove wall 1b4, and an air port is provided corresponding to the second groove wall 1b5. More specifically, a part of the guide groove 1b21 is disposed on the first groove wall 1b4, and a part can be disposed on the second groove wall 1b5. The guide groove disposed on the first groove wall 1b4 is connected to the guide groove disposed on the second groove wall 1b5. Thus, the fluid entering through the air port needs to flow along the second groove wall 1b5 first, then flow to the first groove wall 1b4 opposite to the second groove wall 1b5, and then flow down the guide groove on the first groove wall 1b4 into the connecting hole 1b3.

[0069] Preferably, the microchannel defined by the first groove wall 1b4 extends in a tortuous manner along the surface of the first groove wall 1b4. Preferably, the microchannel defined by the second groove wall 1b5 extends in a tortuous manner along the surface of the second groove wall 1b5.

[0070] Preferably, the central angle corresponding to the trajectory of the fluid flowing into the microchannel and then into the connecting hole 1b3 is greater than or equal to 120°. More preferably, the central angle corresponding to the trajectory of the fluid flowing into the microchannel and then into the connecting hole 1b3 is greater than or equal to 180°.

[0071] In some embodiments, the cover 1b includes an annular sidewall 1b6, and at least a portion of the guide channel extends along the outer surface of the annular sidewall to form an annular shape.

[0072] As an example, the microchannel includes a first channel and a second channel, which are connected end-to-end to form a closed ring. After fluid flows into the microchannel, some fluid flows into the connecting hole 1b3 along the first channel, and some fluid flows into the connecting hole 1b3 along the second channel. This achieves both waterproofing and allows sufficient air to flow into the connecting hole 1b3. The first and second channels can have different circumferential extension lengths. Of course, the first and second channels can also have the same circumferential extension length.

[0073] As an example, the microchannel extends circumferentially along the annular sidewall to form an unclosed ring, allowing air to flow in from one end of the unclosed ring, with the connecting hole 1b3 located at the other end. Preferably, the central angle of the unclosed ring is greater than or equal to 180°.

[0074] As an example, the microchannels extend in a spiral shape along the annular sidewalls in the circumferential direction.

[0075] In some embodiments, referring to 5, the cover 1b includes an annular sidewall 1b6 and a cavity 1b7 located inside the annular sidewall 1b6. The annular sidewall 1b6 is in close contact with the bracket 2 and surrounds a portion of the bracket 2. The housing assembly 1 also includes a sealing ring 4 disposed around the annular sidewall 1b6. The sealing ring 4 is disposed between the microchannel 11 and the battery compartment 21 and provides a seal between the annular sidewall 1b6 and the housing 1a. A connecting hole 1b3 connects the microchannel 11 and the cavity 1b7, and the cavity 1b7 connects the battery compartment 21. Thus, external fluid mainly flows into the battery compartment 21 through the microchannel 11, the connecting hole 1b3, and the cavity 1b7. Fluid ejected during battery depressurization mainly flows out through the cavity 1b7 and the connecting hole 1b3. The microchannel 11 and the air vent flow out. Furthermore, the cavity 1b7 can store a portion of the fluid ejected during battery depressurization. The fluid ejected during battery depressurization can be buffered after flowing into the cavity 1b7, thereby providing safety during battery depressurization.

[0076] It should be noted that when the sealing ring 4 is positioned between the annular sidewall 1b6 and the housing 1a, it is compressed and undergoes elastic deformation to ensure the sealing effectiveness of the sealing ring 4. In some embodiments, the annular sidewall 1b6 is recessed to form a sealing groove 1b6', the microchannel 11 is located at the bottom of the sealing groove 1b6', a portion of the sealing ring 4 is accommodated within the sealing groove 1b6', the sealing ring 4 defines the boundary of the microchannel 11, and the other portion of the sealing ring 4 extends out of the opening of the sealing groove 1b6' and is compressed by the housing 1a to undergo elastic deformation. The sealing groove 1b6' effectively limits the sealing ring 4 when the cover 1b is installed on the housing assembly 1, preventing unintended displacement of the sealing ring 4 and thus affecting its sealing effect.

[0077] In other embodiments, the sealing groove 1b6' and the microchannel 11 are located at two different positions on the cover 1b.

[0078] It should be noted that, in order to ensure the sealing effect of the sealing ring 4, the sealing ring 4 is set in the area of ​​the annular sidewall 1b6 of the cover 1b away from the bracket 2. When the sealing groove 1b6' and the microchannel 11 are respectively set in two different positions of the cover 1b, the sealing groove 1b6' is further away from the bracket 2 than the microchannel 11.

[0079] In some embodiments, please refer to Figure 6 and Figure 7One of the bracket 2 and the cover 1b includes a snap-fit ​​groove 1b8, and the other includes a snap-fit ​​protrusion 22. The snap-fit ​​groove 1b8, the snap-fit ​​protrusion 22, and the battery compartment 21 are located on the same side of the sealing ring 4 to ensure the sealing effectiveness of the sealing ring 4. The snap-fit ​​protrusion 22 and the snap-fit ​​groove 1b8 are in clearance fit, allowing the cavity 1b7 to be fluidly connected to the battery compartment 21. Specifically, the presence of the sealing ring 4 leaves a third gap 12 between the cover 1b and the inner wall of the housing 1a. Due to the clearance fit between the snap-fit ​​protrusion 22 and the snap-fit ​​groove 1b8, a fourth gap 13 is formed between the snap-fit ​​protrusion 22 and the snap-fit ​​groove 1b8. The third gap 12 and the fourth gap 13 are connected, and the fourth gap 13 is connected to the cavity 1b7. The battery compartment 21 has an open opening 211, thereby allowing the cavity 1b7 to be fluidly connected to the battery compartment 21. For example, in this embodiment, please refer to Figure 7 The bracket 2 is provided with a buckle protrusion 22, and the cover 1b is provided with a buckle groove 1b8. The buckle protrusion 22 and the buckle groove 1b8 are engaged to make the bracket 2 and the cover 1b detachably connected.

[0080] In some embodiments, the cover 1b and the housing 1a are clearance-fitted, and the gap between them forms an air vent.

[0081] In other embodiments, please refer to Figure 3 When the microchannel 11 is located at the bottom of the sealing groove 1b6', in order to ensure that the outside air can smoothly enter the microchannel 11, the cover 1b is provided with a connecting groove 1b9, which forms the air port mentioned above.

[0082] In some embodiments, at least a portion of the microchannel 11 is corrugated, or the fluid can undergo at least three significant turns during its flow along the microchannel 11, thereby enabling the microchannel 11 to block the liquid and ensure that the power assembly 100 meets at least an IPX4 waterproof rating.

[0083] It should be noted that the specific shape of the microchannel 11 described above is jointly defined by the first baffle 1b231 and the second baffle 1b232, and the curvature of the corrugated shape formed by the first baffle 1b231 and the second baffle 1b232 is jointly determined by the first baffle 1b231 and the second baffle 1b232. The number of turns of the fluid during its flow within the microchannel 11 is jointly determined by the number of combinations of the first baffle 1b231 and the second baffle 1b232, which will not be illustrated here.

[0084] For the bracket 2 mentioned above, please refer to Figure 1A sealing element 5 is provided at the end of the bracket 2 away from the cover 1b. The sealing element 5 is located between the housing assembly 1 and the bracket 2. The sealing element 5 is used to seal the inner wall between the bracket 2 and the housing assembly 1. Furthermore, the sealing element 5 is located at the end of the bracket 2 away from the cover 1b, so that the sealing element 5 and the sealing ring 4 together achieve the sealing of the battery compartment 21.

[0085] In some embodiments, please refer to Figure 1 The battery assembly 6 includes a battery 6, a circuit board 7, and a conductive element 8. Both the battery 6 and the circuit board 7 are housed within the battery compartment 21, and the battery 6 is electrically connected to the circuit board 7. The bracket 2 is provided with a conductive hole 23, which communicates with the battery compartment 21. A portion of the conductive element 8 is housed within the battery compartment 21 and electrically connected to the circuit board 7, while another portion of the conductive element 8 extends out of the battery compartment 21 from the conductive hole 23, thereby facilitating the electrical connection between external devices and the conductive element 8, thus enabling the electrical connection between external devices and the power supply assembly 100.

[0086] In some embodiments, please refer to Figure 8 and Figure 9 The cover 1b is provided with a power supply through hole 1b10. The battery 6 assembly also includes a power supply terminal 9, which is electrically connected to the circuit board 7. The power supply terminal 9 is connected to the outside through the power supply through hole 1b10 so that the external power supply can replenish the battery 6 through the power supply terminal 9.

[0087] In this application, the power supply assembly 100 includes a housing assembly 1 and a support 2. The housing assembly 1 is provided with a microchannel 11 and an air port communicating with the outside. The support 2 is disposed in the housing assembly 1 and defines a battery compartment 21 for accommodating the battery 6. The microchannel 11 extends non-linearly to form a tortuous fluid path. The battery compartment 21 communicates with the air port through the microchannel 11, thereby maintaining normal communication with the outside. The above structure allows the housing 1a to communicate with the external environment through the microchannel 11 and the air vent, realizing the function of the microphone hole in the existing electronic atomizing device. Since the microchannel 11 in this application is arranged in a tortuous manner on the housing assembly 1, the tortuous fluid path formed by the microchannel 11 can extend the path of external liquid entering the housing assembly 1 through the microchannel 11, thereby improving the waterproof capability of the power assembly 100. Furthermore, since the battery compartment 21 is defined by the bracket 2 arranged in the housing assembly 1, the microchannel 11 is configured to communicate with the battery compartment 21, so that the battery compartment 21 can be depressurized through the microchannel 11, thereby maintaining a stable pressure in the battery compartment 21 and improving the safety of the battery assembly 6.

[0088] This application also provides embodiments of electronic atomizing devices; please refer to [link / reference]. Figure 10The electronic atomizing device 200 includes the aforementioned power supply component 100, as well as an airflow sensor Q and an atomizer 101. The airflow sensor Q is configured to sense changes in airflow in the atomizer 101 and thereby control the power supply component 100 to provide power to the atomizer 101. A microchannel 11 is connected to the airflow sensor Q to ensure its proper operation. Alternatively, the microchannel 11 is connected to the atomizer 101, allowing air to enter the microchannel 11 through an air inlet and flow through the microchannel 11 to the atomizer 101 when the aerosol generated by the atomizer 101 is drawn in, thus providing air to the atomizer 101. It should be noted that the airflow sensor Q is located downstream of the microchannel 11 along the airflow direction.
