Technical Field

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

[0002] To ensure the sealing performance of the atomizing device, conventional atomizing devices require separate seals for key components such as the atomizer interface, atomizer connection, and airflow sensor to achieve local sealing.

[0003] This application provides an atomizing host and atomizing device, which can achieve sealing of multiple key parts of the atomizing device with only one sealing element.

[0004] In some embodiments, an atomizing mod is provided, configured for use in conjunction with an atomizer, the atomizing mod including a base assembly, a seal, and an airflow sensor, wherein...

[0005] The base assembly has an air intake channel that communicates with the outside air.

[0006] A sealing element is fitted onto the base assembly and located between the base assembly and the atomizer; when the atomizing host and the atomizer are assembled, the side of the sealing element away from the base assembly seals against the atomizer and forms a closed air chamber with the atomizer; the atomizer has an atomization channel, and the air chamber connects the atomization channel and the air inlet channel.

[0007] An airflow sensor is mounted on the base assembly and forms an air passage with the air chamber. The airflow sensor is used to respond to changes in air pressure within the air chamber and to transmit an electrical signal to the atomizer.

[0008] In some embodiments, the seal includes a body portion and a first protrusion portion. The body portion is sleeved on the base assembly. The body portion has an air inlet hole communicating with the air inlet channel and a detection hole communicating with the airflow sensor. The first protrusion portion protrudes from the side of the body portion away from the base assembly and surrounds the air inlet hole and the detection hole. The end of the first protrusion portion away from the body portion elastically abuts against the bottom of the atomizer, so that the first protrusion portion, the body portion, and the atomizer enclose and form the air chamber.

[0009] In some embodiments, the first protrusion extends obliquely from the body portion in a direction away from the body portion. The first protrusion is capable of elastic deformation and has a relaxed state and a tightened state. When the first protrusion is in the relaxed state, the first protrusion can separate from the atomizer. When the first protrusion is in the tightened state, the first protrusion can tighten against the atomizer.

[0010] In some embodiments, the first protrusion is disposed around the periphery of the body portion, and the first protrusion extends obliquely toward the center of the body portion;

[0011] And / or, the thickness of the first protrusion gradually decreases from the end near the body portion toward the end away from the body portion.

[0012] In some embodiments, the seal includes a second protrusion, which protrudes from the first protrusion on the same side of the body portion. The second protrusion surrounds the air inlet and has a notch on its periphery, which connects the air inlet and the air chamber.

[0013] When the atomizing host and the atomizer are assembled in place, the second protrusion is configured to abut against the atomizer to restrict the movement of the atomizer relative to the installation direction of the atomizing host.

[0014] In some embodiments, the height by which the second protrusion protrudes relative to the body portion is less than the height by which the first protrusion protrudes relative to the body portion;

[0015] And / or, the height of the first protrusion relative to the body portion is 0.15 to 0.2 mm.

[0016] In some embodiments, the base assembly includes a housing and a bracket disposed within the housing. The bracket includes a mounting portion, and the seal has a receiving groove on the side near the base assembly. The mounting portion is embedded in the receiving groove, and the periphery of the seal is interference-fitted with the inner wall of the housing.

[0017] In some embodiments, the bracket includes a third protrusion that protrudes from the mounting portion toward the seal and passes through a detection hole in the seal. The third protrusion has a sensing channel, and the bracket has a receiving groove communicating with the sensing channel on the side opposite to the third protrusion.

[0018] The base assembly also includes a circuit board disposed on the side of the bracket away from the seal, the circuit board being connected to the airflow sensor, the airflow sensor being disposed in the receiving groove and communicating with the air chamber through the sensing channel.

[0019] In some embodiments, electrodes are provided on the circuit board, and the electrodes pass through the bracket and the connection hole to enable the electrodes to be connected to the atomizer;

[0020] And / or, the bracket is provided with a first magnetic element on the side near the seal, the first magnetic element being exposed in the connection hole so that the first magnetic element can be connected to the atomizer.

[0021] In some embodiments, an atomizing device is provided, including an atomizer and an atomizing host as described in any of the above embodiments, wherein the atomizing host is detachably connected to the atomizer and electrically connected to the atomizer for controlling the operation of the atomizer.

[0022] In the atomizing host provided in this application embodiment, when the atomizing host and the atomizer are assembled, the sealing element can abut against the atomizer, so that the sealing element can seal the atomizer and effectively prevent the aerosol matrix from leaking. Secondly, the sealing element can serve as a connecting component between the air intake channel and the atomization channel, ensuring the continuity and airtightness of the air intake channel and the atomization channel after the atomizer and the host are assembled, and maintaining a stable air pressure environment during the atomization process. In addition, the sealing element can also form an air chamber with the atomizer. This air chamber can be directly used as a negative pressure chamber for the airflow sensor to detect changes in air pressure in the atomization channel, eliminating the need for a separate sealing element for the airflow sensor, optimizing the internal space of the atomizing device, and thus facilitating the miniaturization design of the atomizing device.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0046] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the atomizing device in some embodiments of this application. Figure 2 yes Figure 1 A cross-sectional schematic diagram of the atomizing device in the embodiment. Figure 3 yes Figure 1 An exploded view of the atomizing device in the embodiment.

[0047] This application provides an atomizing device, characterized in that it includes an atomizer 20 and an atomizing host 10, the atomizing host 10 and the atomizer 20 are detachably assembled and used, the atomizing host 10 is electrically connected to the atomizer 20 and is used to control the operation of the atomizer 20.

[0048] Please see Figure 4 , Figure 4 yes Figure 1 A cross-sectional schematic diagram of the atomizer in the embodiment. The atomizer 20 includes a housing 22 and a cover 23. The housing 22 and the cover 23 enclose an inner cavity 24. An atomizing core is disposed in the inner cavity 24, and an aerosol matrix is ​​stored in the inner cavity 24. The atomizing core is used to heat the aerosol matrix and generate aerosol. The atomizer 20 has an atomization channel 21 that penetrates the cover 23 and the mouthpiece 221. The mouthpiece 221 can be part of the housing 22 or a separate structure from the housing 22.

[0049] Please see Figure 5 and Figure 6 , Figure 5 yes Figure 1 A schematic diagram of the atomizing host in the embodiment. Figure 6 yes Figure 5 A cross-sectional view of the atomizing host in the embodiment. The atomizing host 10 includes a base assembly 13, a seal 12, and an airflow sensor 134.

[0050] The base assembly 13 has an air intake channel 11 that communicates with the outside air. The base assembly 13 introduces outside air into the atomization channel 21 of the atomizer 20 through the air intake channel 11 to meet the user's air supply needs during inhalation. A seal 12 is fitted onto the base assembly 13 and located between the base assembly 13 and the atomizer 20. The base assembly 13 provides stable support for the seal 12, while the seal 12 protects the various components of the base assembly 13, preventing dust and liquid from entering critical internal components. When the atomizer 10 and atomizer 20 are assembled, the side of the seal 12 facing away from the base assembly 13 seals against the atomizer 20, forming a closed air chamber 60. The air chamber 60 connects the atomization channel 21 and the air intake channel 11.

[0051] An airflow sensor 134 is disposed on the base assembly 13 and forms an air passage communication with the air chamber 60. The airflow sensor 134 is used to respond to changes in air pressure in the air chamber 60 and to transmit an electrical signal to the atomizer 20.

[0052] In the atomizing host 10 provided in this application embodiment, when the atomizing host 10 and the atomizer 20 are assembled, the sealing member 12 can abut against the atomizer 20, so that the sealing member 12 can seal the atomizer 20 and effectively prevent the aerosol matrix from leaking. Secondly, the sealing member 12 can serve as a connecting component between the air intake channel 11 and the atomization channel 21, ensuring the continuity and airtightness of the air intake channel 11 and the atomization channel 21 after the atomizer 20 is assembled with the host, and maintaining a stable air pressure environment during the atomization process. In addition, the sealing member 12 can also form an air chamber 60 with the atomizer 20. This air chamber 60 can be directly used as a negative pressure chamber for the airflow sensor 134 to detect changes in air pressure inside the atomization channel 21, eliminating the need for a separate setting for the sealing member 12 of the airflow sensor 134, optimizing the internal space setting of the atomizing device, and thus facilitating the miniaturization design of the atomizing device.

[0053] Please see Figures 7 to 9 , Figure 7 yes Figure 5 A magnified view of a portion of point A in the embodiment. Figure 8 yes Figure 5 A schematic diagram of the seal from one perspective in the embodiment. Figure 9 yes Figure 5A schematic diagram of the seal from another perspective in the embodiment. In some embodiments, the seal 12 includes a body portion 123 and a first protrusion 121. The body portion 123 is sleeved on the base assembly 13, and the body portion 123 has an air inlet 127 communicating with the air inlet channel 11, and a detection hole 125 communicating with the airflow sensor 134. The first protrusion 121 protrudes from the side of the body portion 123 away from the base assembly 13, and the first protrusion 121 surrounds the air inlet 127 and the detection hole 125. The end of the first protrusion 121 away from the body portion 123 elastically abuts against the bottom of the atomizer 20, so that the first protrusion 121, the body portion 123 and the atomizer 20 enclose an air chamber 60.

[0054] In this embodiment, the first protrusion 121 elastically abuts against the bottom of the atomizer 20, achieving a good sealing effect and preventing air leakage. The design of the first protrusion 121 surrounding the air inlet 127 and the detection hole 125 protects the airflow sensor 134 from external interference.

[0055] Please see Figure 7 In some embodiments, the first protrusion 121 extends obliquely from the body portion 123 in a direction away from the body portion 123. The first protrusion 121 is capable of elastic deformation and has a relaxed state and a tightened state. When the first protrusion 121 is in the relaxed state, the first protrusion 121 can separate from the atomizer 20. When the first protrusion 121 is in the tightened state, the first protrusion 121 can tighten against the atomizer 20.

[0056] For example, the first protrusion 121 is arranged around the periphery of the body portion 123, and the first protrusion 121 extends obliquely toward the center of the body portion 123. That is, the distance from the end of the first protrusion 121 away from the body portion 123 to the center of the body portion 123 is closer than the distance from the end of the first protrusion 121 closer to the body portion 123 to the center of the body portion 123. When the atomizing host 10 and the atomizer 20 are assembled, the opposite sides of the first protrusion 121 are subjected to a double compression from the base assembly 13 and the atomizer 20, causing the first protrusion 121 to undergo elastic deformation. Because the design of the first protrusion 121 makes it extend at an angle toward the center of the main body 123, the first protrusion 121 is more likely to fold inward when squeezed by the atomizer 20, which further makes the first protrusion 121 and the atomizer 20 form an interference fit, thereby ensuring the stability and sealing of the atomizer host 10 and the atomizer 20 after assembly.

[0057] In some embodiments, the first protrusion 121 extends obliquely away from the center of the body portion 123, meaning the distance from the end of the first protrusion 121 near the body portion 123 to the center of the body portion 123 is closer than the distance from the end of the first protrusion 121 away from the center of the body portion 123. This design allows the first protrusion 121 to easily fold outward when squeezed by the atomizer 20, thereby creating an interference fit between the first protrusion 121 and the atomizer 20.

[0058] Understandably, since the first protrusion 121 will fold when the atomizer 20 and the atomizing host 10 are assembled, even if the atomizer 20 and the atomizing host 10 become loose during use, for example, if the atomizer 20 and the atomizing host 10 are relatively far apart along the assembly direction, the first protrusion 121 can rely on its elastic recovery characteristics to at least partially extend from the folded state back to its original shape, thereby maintaining contact with the atomizer 20 and ensuring the sealing performance of the air chamber 60.

[0059] Please continue reading. Figure 7 In some embodiments, the thickness of the first protrusion 121 gradually decreases from the end near the body portion 123 towards the end away from the body portion 123. This gradual thickness design optimizes the elastic deformation characteristics of the first protrusion 121. When pressure is applied by the atomizer 20, the end of the first protrusion 121 away from the body portion 123 is more prone to deformation, while the end near the body portion 123 maintains sufficient support. When the atomizer 20 becomes loose from the atomizing host 10, the end of the first protrusion 121 near the body portion 123 can support the end of the first protrusion 121 away from the body portion 123 to extend in its original shape and maintain contact with the atomizer 20.

[0060] Please see Figure 2 , Figure 8 and Figure 9In some embodiments, the seal 12 includes a second protrusion 122, which protrudes from the same side of the body 123 as the first protrusion 121. The second protrusion 122 surrounds the air inlet 127, and a notch 1221 is provided on the periphery of the second protrusion 122, connecting the air inlet 127 and the air chamber 60. When the atomizing host 10 and the atomizer 20 are assembled, the second protrusion 122 is configured to abut against the atomizer 20 to restrict the movement of the atomizer 20 relative to the installation direction of the atomizing host 10. The second protrusion 122 and the first protrusion 121 can work together to restrict the movement of the atomizer 20 relative to the installation direction of the atomizing host 10. The second protrusion 122 can prevent the first protrusion 121 from being over-compressed, thus ensuring the recovery performance of the first protrusion 121. Meanwhile, the second protrusion 122 is arranged around the air inlet 127, which can effectively connect the air intake channel 11 and the atomizing channel 21, and improve the gas flow rate between the air intake channel 11 and the atomizing channel 21.

[0061] In some embodiments, the height of the second protrusion 122 protruding relative to the body portion 123 is less than the height of the first protrusion 121 protruding relative to the body portion 123. This design ensures that the first protrusion 121 and the atomizer 20 are interference-fitted to guarantee the sealing performance of the air chamber 60, while also preventing excessive deformation of the first protrusion 121.

[0062] In some embodiments, the height of the first protrusion 121 protruding relative to the body portion 123 is 0.15 to 0.2 mm. Optionally, the height of the first protrusion 121 protruding relative to the body portion 123 is 0.15 mm, 0.16 mm, 0.17 mm, 0.18 mm, 0.19 mm, or 0.2 mm, and no specific limitation is made here.

[0063] Please see Figure 6 , Figure 10 and Figure 11 , Figure 10 yes Figure 5 A partial structural diagram of the atomizing host in the embodiment. Figure 11 yes Figure 10 A partial cross-sectional view of the atomizing host in the embodiment. In some embodiments, the base assembly 13 includes a housing 133 and a bracket 131 disposed within the housing 133. The bracket 131 includes a mounting portion 1312. The sealing member 12 has a receiving groove 124 on the side near the base assembly 13. The mounting portion 1312 is embedded in the receiving groove 124, and the periphery of the sealing member 12 is interference-fitted with the inner wall of the housing 133.

[0064] The receiving groove 124 is stepped, and the orthographic projection of the end of the receiving groove 124 near the first protrusion 121 in the depth direction covers the orthographic projection of the end of the receiving groove 124 away from the first protrusion 121 in the depth direction. The mounting part 1312 is embedded in the stepped receiving groove 124, which can effectively enhance the connection stability between the seal 12 and the bracket 131 and prevent displacement or loosening during use.

[0065] An assembly space for accommodating the atomizer 20 is formed within the outer casing 133. When the atomizer 20 is assembled with the atomizing host 10, it can be directly inserted into the outer casing 133, allowing the bottom of the atomizer 20 to elastically abut against the sealing member 12 and form an air chamber 60. The interference fit between the periphery of the sealing member 12 and the inner wall of the outer casing 133 further prevents aerosol matrix leaking from the atomizer 20 from seeping into other components through the gap between the sealing member 12 and the outer casing 133, further improving the sealing performance of the air chamber 60.

[0066] Please see Figure 11 In some embodiments, the bracket 131 includes a third protrusion 1313, which protrudes from the mounting portion 1312 toward the seal 12 and passes through the detection hole 125 of the seal 12. The third protrusion 1313 is provided with a sensing channel 1311, and the bracket 131 is provided with a receiving groove 1314 communicating with the sensing channel 1311 on the side away from the third protrusion 1313.

[0067] The base assembly 13 also includes a circuit board 132 disposed on the side of the bracket 131 away from the seal 12. The circuit board 132 is connected to the airflow sensor 134. The airflow sensor 134 is disposed in the receiving groove 1314 and is connected to the air chamber 60 through the sensing channel 1311.

[0068] Understandably, the seal 12 is made of a flexible, easily deformable material, while the bracket 131 is made of a rigid material. The design of the third protrusion 1313 passing through the detection hole 125 prevents the seal 12 from deforming and causing the detection hole 125 to close, allowing airflow to be smoothly transmitted from the air chamber 60 to the airflow sensor 134 in the receiving groove 1314, thereby ensuring that the sensor can detect changes in airflow in real time and accurately. Secondly, the connection design between the circuit board 132 and the airflow sensor 134 makes signal transmission more efficient and stable, avoiding signal loss due to excessively long lines or poor contact. In addition, placing the airflow sensor 134 in the receiving groove 1314 and communicating with the air chamber 60 through the sensing channel 1311 not only ensures the safety and stability of the sensor but also effectively prevents the influence of the external environment on the sensor, avoiding damage to the airflow sensor 134 from the erosion of the aerosol matrix.

[0069] Please continue reading. Figure 11 In some embodiments, an electrode 135 is provided on the circuit board 132, and the electrode 135 passes through the bracket 131 and the connection hole 126 so that the electrode 135 can be connected to the atomizer 20.

[0070] Furthermore, a first magnetic chuck 136 is provided on the side of the bracket 131 near the seal 12, and the first magnetic chuck 136 is exposed in the connection hole 126 so that the first magnetic chuck 136 can be connected to the atomizer 20. Optionally, the first magnetic chuck 136 is annular, and the electrode 135 is disposed in the middle of the annular first magnetic chuck 136. Figure 3 As shown, the bottom of the atomizer 20 is provided with a second magnetic component 25. The first magnetic component 136 and the second magnetic component 25 attract each other to achieve a stable connection between the atomizer 20 and the atomizing host 10 when the atomizer 20 and the atomizing host 10 are assembled.

[0071] Please see Figure 6 In some embodiments, the outer casing 133 includes a detachably connected bottom cover 1331 and a casing body 1332, including but not limited to snap-fit ​​or threaded connections. The bottom cover 1331 can be connected sequentially to the circuit board 132, the bracket 131, and the seal 12, and then the bottom cover 1331 can be fixedly connected to the casing body 1332. This facilitates the assembly and maintenance of the atomizing host 10, while ensuring the precise positioning of the internal components.

[0072] Please see Figure 12 , Figure 12 yes Figure 1 A schematic diagram illustrating the connection relationship between the atomizing device and the first and second sealing plugs in this embodiment. In some embodiments, to ensure the sealing performance of the atomizing device during transportation, the atomizing device further includes a first sealing plug 26 and a second sealing plug 30. The first sealing plug 26 is used to seal the mouthpiece 221 of the atomizer 20. The second sealing plug 30 is used to seal the air intake channel 11 when the atomizer 20 and the atomizing host 10 are assembled. The air intake channel 11 is coaxially arranged with at least a portion of the atomizing channel 21, and the air intake channel 11 passes through the base assembly 13. The second sealing plug 30 is inserted into the air intake hole 127 of the sealing member 12 through the air intake channel 11, and is press-fitted with the air intake hole 127 to isolate the atomizing channel 21 from the air intake channel 11. The projection of the portion of the second sealing plug 30 inserted into the air intake hole 127 in the depth direction of the air intake hole 127 covers the projection of the air intake hole 127 in its own depth direction, so that the second sealing plug 30 is tightly connected to the sealing member 12, improving the sealing performance.

[0073] Please see Figure 13 , Figure 13 yes Figure 1The diagram illustrates the connection relationship between the atomizer and the first and third sealing plugs in this embodiment. In some embodiments, to meet cartridge replacement requirements, the atomizer 20 is detachably connected to the atomizing host 10, and multiple atomizers 20 can be configured. During transportation, one atomizer 20 is assembled with the atomizing host 10 and packaged as a whole, while the other atomizers 20 can be individually sealed and packaged. Exemplarily, the atomizing device also includes a third sealing plug 50. For atomizers 20 not assembled with the atomizing host 10, the third sealing plug 50 can be inserted into the atomization channel 21 of the atomizer 20 to isolate the atomization channel 21 from external gas, thereby ensuring the sealing performance of the atomizer 20.

[0074] In this application, the materials of the sealing element 12, the first sealing plug 26, the second sealing plug 30, and the third sealing plug 50 include, but are not limited to, elastic silicone, rubber, and other materials with good sealing performance. These materials not only provide a reliable sealing effect but also have excellent chemical resistance and aging resistance, ensuring that a stable sealing state is maintained even after long-term use.

[0075] The above description is only a part of the embodiments of this application and does not limit the scope of protection of this application. Any equivalent device or equivalent process transformation made based on the content of this application specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this application.
