Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, specifically to an atomization device. Background Technology

[0002] With the widespread application of atomizing devices, their transportation and usage scenarios are also becoming increasingly diverse. For example, when atomizing devices are transported at high altitudes or by air, pressure changes can cause the external atmospheric pressure to be significantly lower than the internal atmospheric pressure of the atomizing device. This large pressure difference can cause the atomizing matrix inside the device to be squeezed outwards under pressure. This can lead to leakage in the atomizing device before it is used after transportation, affecting its normal operation. Utility Model Content

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0029] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0030] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0031] Existing atomizing devices are prone to leakage in environments with large pressure differences.

[0032] In this application, the sealing plug assembly 5 cooperates with the airflow channel 1003 to isolate the airflow channel 1003 from the external gas, achieving oil-gas separation inside the atomizing device. Furthermore, the cooperation between the first sealing element 3 and the sealing plug assembly 5 improves the sealing performance of the airflow channel 1003. The first sealing element 3 not only seals the airflow channel 1003 but also allows for the installation of the airflow sensing component 4 within the atomizing device, optimizing the internal structure and reducing the number of components. This reduces the production cost of the atomizing device by preventing leakage of the atomizing matrix in environments with changing air pressure. Moreover, the cooperation between the sealing plug assembly and the airflow channel, specifically by simultaneously setting sealing structures at both the inlet and outlet, isolates the airflow channel from the external gas, providing the atomizing device with its first layer of sealing protection.

[0033] The atomizing device described in this application embodiment can maintain stable operation during long-term transportation in environments with large internal and external pressure differences, or during long-term storage when not in use, and will not experience leakage of the atomizing matrix.

[0034] Please refer to Figures 1 to 6 In one embodiment, an atomizing device is provided, which mainly includes a housing assembly 1, an atomizing assembly 2, a first sealing element 3, an airflow sensing assembly 4, and a sealing plug assembly 5. The housing assembly 1 includes an air inlet 1001, an air outlet 1002, an airflow channel 1003, and a liquid storage chamber 1004. The airflow channel 1003 connects the air inlet 1001 and the air outlet 1002. The air inlet 1001 provides a pathway for external airflow to flow into the airflow channel 1003, and the air outlet 1002 provides a pathway for internal airflow to flow to the outside. Thus, the airflow circulation of the atomizing device can be completed by external airflow passing through the air inlet 1001, the airflow channel 1003, and the air outlet 1002. The liquid storage chamber 1004 stores an atomizing matrix, which may be a mixed liquid comprising propylene glycol, glycerin, food flavoring, or fragrance.

[0035] Atomizing component 2 is disposed within the liquid storage chamber 1004. Atomizing component 2 has an atomizing channel 201, which is connected to the airflow channel 1003. Atomizing component 2 is used to heat the atomizing matrix and form an aerosol. The airflow channel 1003 is configured to transport the aerosol formed within the atomizing channel 201 to the air outlet 1002. In other words, the atomizing matrix in the liquid storage chamber 1004 flows to the atomizing component 2, is heated and atomized by the atomizing component 2, and then flows to the airflow channel 1003 before being delivered to the air outlet 1002.

[0036] A first sealing element 3 is disposed within the housing assembly 1, and the first sealing element 3 has an air guide hole 301 communicating with the airflow channel 1003. The air guide hole 301 can be regarded as a hole through which the airflow entering from the air inlet 1001 is directed to the atomizing assembly 2. The airflow sensing component 4 is disposed on the first sealing element 3 and is used to detect changes in airflow within the airflow channel 1003. Thus, the operation of the atomizing assembly 2 can be controlled by detecting changes in airflow.

[0037] The sealing plug assembly 5 simultaneously seals both the air inlet 1001 and the air outlet 1002, isolating the airflow channel 1003 from the external gas. At least a portion of the sealing plug assembly 5 passes through the air guide hole 301 and seals it. The sealing plug assembly 5 may include at least two sealing plugs, with at least one sealing plug sealingly connected to the air inlet 1001 and at least one sealing plug sealingly connected to the air outlet 1002. This isolates the airflow channel 1003 from the external gas. Consequently, changes in external gas pressure will not affect the internal structure of the atomizing device, ensuring stable operation during long-term transport in environments with large internal and external pressure differences, or during long-term storage when not in use, preventing leakage of the atomizing matrix.

[0038] At least a portion of the sealing plug is inserted into the air guide hole 301 and forms a sealed connection with the first sealing member 3, which can form a secondary seal for the air inlet 1001 or the air outlet 1002 of the airflow channel 1003. This can prevent the sealing plug assembly 5 from generating an air gap under air pressure, allowing external gas to enter the airflow channel 1003, thereby improving the sealing performance and liquid storage stability of this atomizing device.

[0039] Furthermore, the first sealing element 3 not only seals the airflow channel 1003, but also enables the airflow sensing component 4 to be installed inside the atomizing device, thus optimizing the internal structure of the atomizing device, reducing the number of parts, and thereby reducing the production cost of the atomizing device.

[0040] In one embodiment, reference is made to Figure 3 and Figure 4 As shown, the first seal 3 is positioned near the air inlet 1001. The airflow channel 1003 includes an air inlet section 10031, which connects the air inlet 1001 and the air guide hole 301. The air inlet section 10031 can be the channel area of ​​the airflow channel 1003 located between the air inlet 1001 and the air guide hole 301 of the first seal 3. The sealing plug assembly 5 may include a first sealing plug 51, which extends through the air inlet 1001 and passes through the air inlet section 10031 to form a seal on the air inlet section 10031. The first sealing plug 51 can seal the air inlet section 10031 of the airflow channel 1003, thereby improving the sealing performance of the airflow channel 1003 and achieving oil-gas separation inside the atomizing device.

[0041] In one or more embodiments, the outer surface of the first sealing plug 51 or the first sealing plug 51 itself is made entirely of rubber material. Alternatively, the outer surface of the first sealing plug 51 or the first sealing plug 51 itself is made entirely of silicone material. Or, the outer surface of the first sealing plug 51 or the first sealing plug 51 itself is made entirely of plastic material.

[0042] In one embodiment, reference is made to Figure 3 and Figure 4 As shown, the atomizing device further includes a battery bracket 10106, disposed within the housing assembly 1 and embedded in the airflow channel 1003. The battery bracket 10106 provides structural support for the battery 11. The battery bracket 10106 may include a first through hole 601 and a first accommodating cavity 603, and the battery bracket 10106 is sealed to the housing assembly 1. The first through hole 601 communicates with the atomizing channel 201. The sealed connection between the battery bracket 10106 and the housing assembly 1 prevents airflow from entering the atomizing device from entering the airflow channel 1003 through the connection between the battery bracket 10106 and the housing assembly 1, thereby improving the sealing performance of the airflow channel 1003.

[0043] The first sealing element 3 may include a first sealing portion 31, which is embedded in the first accommodating cavity 603 and is sealed to the battery bracket 10106. The sealing connection between the first sealing portion 31 and the battery bracket 10106 prevents airflow from entering the airflow channel 1003 from the connection between the first sealing portion 31 and the battery bracket 10106. The air guide hole 301 is formed on the first sealing portion 31 and communicates with the first through hole 601. The first sealing plug 51 is sealed to the first sealing portion 31 to seal the air intake section 10031, thereby improving the sealing performance of the airflow channel 1003 and achieving oil-gas separation inside the atomizing device.

[0044] In one embodiment, reference is made to Figure 3 and Figure 4As shown, the atomizing device may further include a detection port 602 and a second accommodating cavity 604. The airflow sensing assembly 4 includes an airflow sensor 41 and a circuit board 42 electrically connected to the airflow sensor 41. The circuit board 42 includes a second through hole 4201 communicating with the air guide hole 301. The first sealing member 3 may further include a second sealing part 32 connected to the first sealing part 31. The airflow sensor 41 and the second sealing part 32 are embedded in the second accommodating cavity 604, and the second sealing part 32 is sealingly connected between the battery holder 10106 and the airflow sensor 41. For example, the first sealing part 31 and the second sealing part 32 may be arranged side by side. The airflow sensor 41 may be mounted on the end face of the circuit board 42 near the first sealing member 3. The second sealing part 32 forms a seal at the connection between the airflow sensor 41 and the battery holder 10106, preventing external airflow from entering the airflow channel 1003 through this connection, thereby improving the airtightness of the airflow channel 1003. The second accommodating cavity 604 communicates with the airflow channel 1003 through the detection hole 602, allowing the airflow sensor 41 to detect changes in airflow within the airflow channel 1003. The detected airflow changes can then be used to control the operation of the atomizing assembly 2. The probe of the airflow sensor 41 can be embedded within the detection hole 602.

[0045] In one or more embodiments, the first sealing portion 31 has a first sealing rib 311 protruding from the inner side of the air guide hole 301 towards the first sealing plug 51, and the first sealing rib 311 seals against the first sealing plug 51. The first sealing rib 311 may be circumferentially disposed within the inner side of the air guide hole 301. For example, the first sealing rib 311 and the first sealing portion 31 may be an integral structure. The first sealing rib 311 is elastic; when the first sealing plug 51 is inserted into the air guide hole 301, the first sealing rib 311 undergoes compression deformation and forms a sealing connection with the first sealing plug 51 through an interference fit.

[0046] In one or more embodiments, refer to Figure 4As shown, the atomizing device further includes a first sealing ring 7, which is fitted onto the battery holder 10106 near the first sealing element 3 and is interference-fitted with the housing assembly 1. The first sealing ring 7 can be made of silicone, rubber, or plastic. The outer surface of the battery holder 10106 may have a first sealing groove, and the first sealing ring 7 can be fitted into the first sealing groove. Thus, the interference fit between the first sealing ring 7 and the housing assembly 1 achieves a sealed connection between the housing assembly 1 and the battery holder 10106. The sealing method using the first sealing ring 7 facilitates the assembly of the atomizing device and reduces the structural cost of the sealing connection.

[0047] In summary, the sealing performance of the air section 10031 can be improved by the sealing connection between the first sealing plug 51 and the first sealing part 31, and the sealing connection between the first sealing ring 7 and the battery bracket 10106. Furthermore, the airflow sensor 41 is sealed by the second sealing part 32, enabling the airflow sensor 41 to perform its airflow detection function. This reduces the number of components in the atomizing device and lowers its production cost.

[0048] In one embodiment, reference is made to Figure 3 , Figure 4 as well as Figure 5 As shown, the atomizing device may further include a control button 102. The control button 102 is an operating component used to implement various function controls. The housing assembly 1 includes a mounting portion 1011, which includes a third through hole 10111. The airflow sensing component 4 is disposed between the battery bracket 10106 and the mounting portion 1011. The air guide hole 301 communicates with the third through hole 10111, the control button 102 is mounted on the end face of the mounting portion 1011 away from the battery bracket 10106, and the air inlet 1001 is opened on the control button 102, communicating with the third through hole 10111. The third through hole 10111, the air guide hole 301, and the first through hole 601 cooperate to form the air intake section 10031. For example, the air intake section 10031 may further include a second through hole 4201 located between the third through hole 10111 and the air guide hole 301. This allows external airflow to enter the air intake section 10031 from the air inlet 1001 and then enter the atomization channel 201.

[0049] In one embodiment, reference is made to Figure 4As shown, the mounting portion 1011 has a receiving groove 10011, in which the control button 102 is embedded. The housing assembly 1 may further include a sealing cover 103, on the inner side of which a second sealing rib 1031 is provided. The sealing cover 103 is fitted onto the mounting portion 1011 to seal the receiving groove 10011. The sealing cover 103 is used to seal the receiving groove 10011 (which can also be understood as sealing the control button 102), and the second sealing rib 1031 is interference-fitted with the mounting portion 1011. For example, the second sealing rib 1031 may be arranged around the inner side of the sealing cover 103. The sealing cover 103 has a receiving space, and each of the second sealing ribs 1031 may be arranged around the end face of the sealing cover 103 facing the receiving space. The second sealing ribs 1031 form a sealed connection between the sealing cover 103 and the mounting portion 1011. The second sealing rib 1031 and the sealing cover 103 can be an integral structure.

[0050] The second sealing rib 1031 is elastic, and each of the second sealing ribs 1031 is press-fitted with the mounting part 1011, thereby achieving a multi-layer seal between the mounting part 1011 and the sealing cover 103. Therefore, when the pressure difference between the inside and outside of the atomizing device is large, the probability of external airflow squeezing the multi-layer seal connection between the sealing cover 103 and the mounting part 1011 under pressure, creating an air gap that enters the air inlet 1001 of the atomizing device, is reduced, thus reducing leakage of the atomizing device.

[0051] Furthermore, the first sealing plug 51, inserted into the air intake section 10031, ensures that when the pressure difference between the inside and outside of the atomizing device is large, and the external airflow, under pressure, squeezes the sealing connection between the sealing cover 103 and the mounting part 1011, creating an air gap that enters the internal space of the atomizing device, the first sealing plug 51 seals the air intake section 10031, and the first sealing ring 7 seals the connection between the sealing ring 7 and the battery bracket 10106, thus repeatedly sealing the air intake section 10031. This ensures that external airflow will not enter the airflow channel 1003 through the air intake port 1001. Therefore, even when the atomizing device encounters severe changes in air pressure, the internal air pressure balance of the atomizing device can be maintained.

[0052] Reference Figure 3 and Figure 4As shown, the sealing cover 103 has a fourth through hole 10301 communicating with the air inlet 1001. The first sealing plug 51 is inserted into the fourth through hole 10301 and is interference-fitted with the sealing cover 103. The interference fit between the first sealing plug 51 and the sealing cover 103 facilitates the assembly of the first sealing plug 51 and the sealing cover 103, thereby facilitating the insertion of the first sealing plug 51 into the air intake section 10031 and achieving multiple seals on the air inlet 1001 and the air intake section 10031, thereby improving the airtightness of the airflow channel 1003.

[0053] If only the first sealing plug 51 is provided and the sealing cap 103 is not provided, air leakage will occur at the receiving groove 10011. If only the sealing cap 103 is provided and the first sealing plug 51 is not provided, when the pressure difference between the inside and outside of the atomizing device is large, the sealing cap 103 cannot achieve a complete seal to the inside of the atomizing device. For example, air pressure will squeeze the sealing connection between the sealing cap 103 and the housing assembly 1, which may create an air gap that allows external gas to enter the inside of the atomizing device. Therefore, under the first seal of the sealing cap 103, the multiple seals of the air inlet section 10031 by the first sealing plug 51 ensure that external airflow does not enter the atomizing channel 201.

[0054] Reference Figure 3 and Figure 4 As shown, the first sealing plug 51 may include a first sealing portion 511 and a second sealing portion 512. The first sealing portion 511 is interference-fitted with the air guide hole 301 of the first sealing portion 31, and the second sealing portion 512 is interference-fitted with the fourth through hole 10301. The diameter of the first sealing portion 511 is equal to or smaller than the diameter of the second sealing portion 512. The interference fit improves the ease of assembly of the first sealing plug 51. The interference fit between the first sealing portion 511 and the air guide hole 301 on the first sealing portion 31 improves the airtightness of the air intake section 10031. The interference fit between the second sealing portion 512 and the fourth through hole 10301 improves the sealing performance between the sealing cap 103 and the first sealing plug 51. Therefore, when the external airflow compresses the second sealing part 512 and creates an air gap at the seal between the sealing cover 103 and the first sealing plug 51, the external airflow can be blocked by the first sealing part 511, preventing it from continuing to penetrate deeper into the atomizing channel 201 along the air inlet section 10031. By using the first sealing part 511 and the second sealing part 512 to simultaneously provide a double seal for the first sealing member 3 and the air inlet 1001, the sealing performance of the atomizing device can be improved.

[0055] In one or more embodiments, refer to Figure 4 As shown, the first sealing plug 51 may further include an operating part 513, which is disposed at the end of the first sealing plug 51 outside the air inlet 1001. The operating part 513 being located outside the end of the air inlet 1001 facilitates the user in removing or inserting the first sealing plug 51, improving user convenience.

[0056] In one or more embodiments, refer to Figure 4 As shown, the first sealing plug may further include an extension 514, which is disposed at the end of the first sealing plug 51 away from the air inlet 1001, and the extension 514 passes through the first through hole 601 and is adapted to the shape of the first through hole 601. It can form a sealing connection with the first through hole 601 through shape adaptation, so that when the first sealing plug 51 is inserted into the air intake section 10031, the extension 514 is sealed to the first through hole 601, thereby improving the sealing performance of the first sealing plug 51 to the air intake section 10031.

[0057] In some embodiments, the operating part 513 is located at the end of the second blocking part 512 away from the first blocking part 511. The extension part 514 is located at the end of the first blocking part 511 away from the second blocking part 512, and the extension part 514, the first blocking part 511, the second blocking part 512, and the operating part 513 can be an integral structure.

[0058] In one embodiment, reference is made to Figure 3 , Figure 5 as well as Figure 6 As shown, the housing assembly 1 may further include a liquid storage chamber 104 and a shell 101 with an opening at one end. The cross-sectional shape of the shell 101 along its width direction may be circular, rectangular, or other irregular shapes. It is used to protect other components of the atomizing device and to provide structural support. The battery holder 10106 is located inside the shell 101, and the mounting portion 1011 can be regarded as the bottom of the shell 101. For example, the shell 101 may also include a side shell, which cooperates with the mounting portion 1011 to form an assembly cavity for assembling the battery holder 10106 and a receiving groove 10011 for assembling the control button 102, respectively. The control button 102 can form a sealed connection with the side shell.

[0059] The liquid storage chamber 104 is inserted into the outer shell 101 through an opening. An air inlet 1001 is formed at one end of the outer shell 101 away from the liquid storage chamber 104, and an air outlet 1002 is formed at one end of the liquid storage chamber 104 away from the air inlet 1001. An airflow channel 1003 is formed between the liquid storage chamber 104 and the interior of the outer shell 101. The liquid storage chamber 1004 is disposed within the liquid storage chamber 104. The airflow channel 1003 further includes an air outlet section 10032 disposed within the liquid storage chamber 104, connecting the air outlet 1002 with the atomizing channel 201. In other words, the air outlet section 10032 can be considered as the channel region of the airflow channel 1003 located between the air outlet 1002 and the atomizing channel 201.

[0060] The sealing plug assembly 5 further includes a second sealing plug 52, at least partially inserted and sealed within the air outlet section 10032. The second sealing plug 52 seals the air outlet 1002 and the air outlet section 10032, thereby improving the sealing performance of the air outlet section 10032 and preventing external airflow from entering the atomizing channel 201 through the air outlet section 10032 and then entering the liquid storage chamber 1004, which could cause the atomizing matrix in the liquid storage chamber 1004 to overflow. The interference fit between the second sealing plug 52 and the vent pipe 1041 facilitates the removal and insertion of the second sealing plug 52.

[0061] In one example, referencing Figure 5 and Figure 6 As shown, the liquid storage tank 104 may further include a vent pipe 1041 communicating with the air outlet 1002. The vent pipe 1041 is located near the end of the atomizing component 2 and communicates with the atomizing channel 201. The air outlet section 10032 is formed inside the vent pipe 1041. That is, the length of the air outlet section 10032 corresponding to the airflow channel 1003 can be determined by the axial length of the vent pipe 1041. The aerosol in the atomizing channel 201 flows to the air outlet section 10032, and then flows to the air outlet 1002 through the air outlet section 10032.

[0062] The second sealing plug 52 includes a third sealing portion 521, which is inserted into the vent pipe 1041. At least two third sealing ribs 522 are provided on the third sealing portion 521, respectively located on the side of the third sealing portion 521 near the air outlet 1002 and the side away from the air outlet 1002 (which can also be understood as the side near the atomizing channel 201). The third sealing ribs 522 are interference-fitted with the vent pipe 1041. At least one third sealing rib 522 is located on the side of the third sealing portion 521 away from the air outlet 1002, which can prevent the atomizing matrix in the liquid storage chamber 1004 from entering the air outlet section 10032 through the atomizing component 2 and generating capillary action. Capillary action refers to the phenomenon where liquid rises or falls inside a thin tubular object due to the difference between cohesive and adhesive forces and the effect of surface tension, overcoming gravity. This prevents the atomizing matrix from overflowing from the air outlet section 10032 when the user removes the second sealing plug 52.

[0063] At least one of the third sealing ribs 522 is disposed on the side of the third sealing part 521 near the air outlet 1002. The third sealing rib 522 is interference-fitted with the vent pipe 1041. When the pressure difference between the inside and outside of the atomizing device is large, it can reduce the probability that the external airflow will squeeze the connection between the second sealing plug 52 and the vent pipe 1041 under pressure, creating an air gap that enters the atomizing channel 201, thereby reducing the leakage of the atomizing device.

[0064] The second sealing rib 1031 and the third sealing rib 522 are both annular in cross-sectional shape and can be made of elastic materials such as rubber, plastic and silicone, respectively.

[0065] In one or more embodiments, refer to Figure 6As shown, the second sealing plug 52 further includes a third sealing portion 523, which is located at the air outlet 1002 and covers the air outlet 1002. For example, the third sealing portion 523 and the third sealing portion 521 can be an integral structure, wherein the cross-sectional area of ​​the third sealing portion 523 along the radial direction of the vent pipe 1041 is larger than the area of ​​the air outlet 1002, so that when the second sealing plug 52 is inserted into the air outlet section 10032, the third sealing portion 523 can cover the air outlet 1002, thereby sealing the air outlet 1002. Thus, through multiple sealing methods, such as the sealing connection between the third sealing part 523 and the air outlet 1002, the sealing connection between the side of the third sealing part 521 near the air outlet 1002 and the air vent 1041, and the sealing connection between the side of the third sealing part 521 away from the air outlet 1002 and the air vent 1041, the sealing performance of the air inlet section 10031 is improved. This avoids the situation where external airflow enters the atomizing channel 201 due to the air gap created by the compression of external airflow at the sealing connection of the air inlet section 10031.

[0066] In summary, the second sealing plug 52, through the third sealing part 521 and the third sealing part 523, simultaneously seals the air pipe 1041 and the air outlet 1003, thereby improving the sealing performance of the atomizing device.

[0067] In one or more embodiments, the airflow channel 1003 further includes an air outlet section 10032, which connects the air outlet 1002 and the atomizing channel 201. The first sealing member 3 is positioned near the air outlet 1002. For example, the first sealing member 3 can be fixed to the housing assembly 1. The air outlet section 10032 is sealed by the first sealing portion 31 of the first sealing member 3. The airflow sensing assembly 4 can be embedded inside the vent pipe 1041, wherein the airflow sensor 41 can be used to detect changes in airflow in the air outlet section 10032. The operation of the atomizing assembly 2 is controlled based on the changes in airflow in the air outlet section 10032. The airflow channel 1003 is sealed by the first sealing portion 31 of the first sealing member 3, and the airflow sensor 41 is sealed by the second sealing portion 32 of the first sealing member 3, thereby realizing the airflow detection function of the airflow sensor 41. This can reduce the number of components in the atomizing device and reduce the production cost of the atomizing device.

[0068] In one embodiment, reference is made to Figure 5 and Figure 6As shown, the liquid storage chamber 104 also includes a nozzle shell 1042 and a base 1043. The nozzle shell 1042, base 1043, and vent pipe 1041 surround and form a downward-opening liquid storage chamber 1004. The atomizing component 2 is mounted on the base 1043 and located at the opening of the liquid storage chamber 1004 to connect the liquid storage chamber 1004 and the atomizing channel 201. The atomizing matrix in the liquid storage chamber 1004 can automatically flow into the atomizing component 2 under gravity, eliminating the need for additional flow guiding devices or atomizing matrix extraction devices, thus simplifying the structure of the atomizing device and reducing its production cost. The atomizing matrix enters the atomizing component 2 through the opening, and the atomizing component 2 heats the atomizing matrix to form an aerosol. The aerosol enters the outlet section 10032 of the airflow channel 1003 through the atomizing channel 201. The base 1043 can be made of materials including, but not limited to, plastic, ceramic, and metal.

[0069] The outer shell 101 is fitted onto the mouthpiece shell 1042, and the atomizing device may further include a second sealing ring 8, which is fitted onto the mouthpiece shell 1042 and has an interference fit with the outer shell 101. For example, the second sealing ring 8 may be made of silicone, rubber, or plastic. The outer surface of the liquid storage chamber 104 may be provided with a second sealing groove, and the second sealing ring 8 may be fitted into the second sealing groove. Thus, the interference fit between the second sealing ring 8 and the outer shell 101 achieves a sealed connection between the outer shell 101 and the liquid storage chamber 104. The sealing method using the second sealing ring 8 makes the assembly of the atomizing device convenient and reduces the cost of the sealing connection structure of the atomizing device.

[0070] In this embodiment, the second sealing ring 8 is sleeved on the outer periphery of the liquid storage chamber 104, which can seal the connection gap between the liquid storage chamber 104 and the outer shell 101. The first sealing ring 7 is sleeved on the outer periphery of the battery bracket 10106, which can seal the connection gap between the battery bracket 10106 and the outer shell 101. Thus, the first sealing ring 7 and the second sealing ring 8 can seal the connection gaps at the ends of the atomizing device, except for the air inlet 1001 and the air outlet 1002, thereby improving the sealing performance of the atomizing device.

[0071] In one or more embodiments, a mouthpiece is formed on the side of the mouthpiece shell 1042 away from the outer shell 101. The mouthpiece refers to a component that can be held in the mouth and inhaled when the user uses the atomizing device.

[0072] In one embodiment, reference is made to Figure 6As shown, the atomizing assembly 2 further includes an atomizing tube 21, a liquid storage component 22, and an atomizing core 23. The liquid storage component 22 is embedded in the base 1043. The atomizing tube 21 is embedded in the liquid storage component 22 and sleeved on the vent pipe 1041. The atomizing tube 21 has the atomizing channel 201 and a liquid guiding hole communicating with the liquid storage chamber 1004. The atomizing core 23 is embedded in the atomizing tube 21 and communicates with the air outlet section 10032. The atomizing tube 21 cooperates with the base 1043 to define the position of the liquid storage component 22. The liquid guiding hole is used to guide the atomizing matrix in the liquid storage component 22 into the atomizing core 23 so that the atomizing core 23 heats and uniformly atomizes the atomizing matrix. The atomizing tube 21 can be made of stainless steel or similar materials. The atomizing tube 21 is provided with an atomizing channel 201, and the atomizing core 23 is located within the atomizing channel 201. The atomizing tube 21 provides structural support for the atomizing core 23. For example, the end of the atomizing tube 21 away from the air outlet section 10032 is connected to the air inlet section 10031, and the end of the atomizing tube 21 near the air outlet section 10032 is connected to the air outlet section 10032. In addition, at least a portion of the mouthpiece shell 1042 may be made of a transparent or translucent material to facilitate user observation of the internal atomizing matrix.

[0073] Reference Figure 6 As shown, the atomizing device may further include a second sealing element 9, which is located between the atomizing tube 21 and the venting tube 1041 and is press-fitted with the venting tube 1041. The second sealing element 9 ensures a sealed connection at the junction of the venting tube 1041 and the atomizing tube 21, thereby preventing the atomizing matrix in the liquid storage chamber 1004 from entering the air outlet section 10032 through the junction of the venting tube 1041 and the atomizing tube 21, thus preventing oil leakage. Simultaneously, it prevents external airflow from entering the oil storage chamber from the junction of the venting tube 1041 and the atomizing tube 21.

[0074] In one or more embodiments, refer to Figure 3 , Figure 4 , Figure 5 as well as Figure 6As shown, the atomizing device further includes a battery bracket 10106 and a battery 11. The battery bracket 10106 is disposed on the side of the liquid storage chamber 104 away from the air outlet 1003, and a portion of the battery bracket 10106 is inserted into the mouthpiece shell 1042. The battery bracket 10106 includes a limiting cavity 10001 and a fifth through hole 10002. The battery 11 is located in the limiting cavity 10001 and is electrically connected to the atomizing assembly 2. The mouthpiece shell 1042 and the battery bracket 10106 can be detachably connected by means of snap-fit ​​or other methods.

[0075] In one or more embodiments, refer to Figure 3 , Figure 5 as well as Figure 6 As shown, the atomizing device further includes a third sealing element 12, which is disposed between the battery bracket 10106 and the base 1043. The airflow channel 1003 connects the air inlet 1001, the limiting cavity 10001, the atomizing channel 201, and the air outlet 1002 through the fifth through hole 10002. For example, the third sealing element 12 forms an interference fit with the base 1043 and the nozzle shell 1042, respectively. The third sealing element 12 is disposed between the battery bracket 10106 and the base 1043 to seal the connection between the fifth through hole 10002 and the atomizing channel 201, thereby improving the connection sealing between the battery bracket 10106 and the base 1043.

[0076] The battery 11 is electrically connected to the atomizing core 23 to provide power to the atomizing core 23, enabling it to atomize the atomizing matrix. For example, when a negative pressure is generated in the mouthpiece shell 1042, the airflow sensing component 4 detects this airflow change and supplies power to the atomizing core 23, causing it to heat the atomizing matrix to form an aerosol that is introduced into the air outlet section 10032. The circuit board 42 is electrically connected to the battery 11 and is used to manage the power supply to the battery 11. It also controls the operating mode switching and functions of the atomizing device. A portion of the battery holder 10106 is inserted into the mouthpiece shell 1042 and engages with it, thereby achieving a fixed connection between the mouthpiece shell 1042 and the battery holder 10106.

[0077] In summary, this application discloses an atomizing device. The atomizing device uses a sealing plug assembly 5 in conjunction with an airflow channel 1003 to isolate the airflow channel 1003 from external gas, achieving oil-gas separation within the atomizing device. Furthermore, the cooperation between the first sealing element 3 and the sealing plug assembly 5 improves the sealing performance of the airflow channel 1003. The first sealing element 3 not only seals the airflow channel 1003 but also allows for the installation of an airflow sensing component 4 within the atomizing device, optimizing its internal structure, reducing the number of components, and lowering production costs. Simultaneously, based on the aforementioned multi-layered sealing structure, the atomizing device can maintain internal pressure balance even when encountering severe pressure changes.
