[0037] Figure 1 This is a schematic diagram of the internal structure of the atomization device in one embodiment of the present application. Figure 2 yes Figure 1 A partial enlarged schematic diagram of point A in the embodiment. The embodiment of the present application provides an atomizing device, which may include a housing 300, a first atomizer 200 and an atomizer 100, wherein:

[0038] The housing 300 is provided with a mouthpiece 31, which can be used for inhalation by the user. The first atomizer 200 includes a main liquid storage tank 21, a main atomization core assembly 22, a main liquid storage member 24 and a main seal 23. The main atomization core assembly 22 is arranged in the main liquid storage tank 21 and forms a first airway 221. The first airway 221 is connected to the mouthpiece 31 so that the aerosol can be transmitted to the mouthpiece 31 through the first airway 221; the main seal 23 is connected to the main liquid storage tank 21 and forms a sealed main liquid storage chamber, which is used to store the atomized matrix; the main liquid storage member 24 is arranged in the main liquid storage chamber. The main liquid storage member 24 can be made of a porous material such as a cotton core. The main liquid storage member 24 is arranged on the periphery of the first airway 221. The main atomization core assembly 22 can heat the atomized matrix and generate an aerosol for the user to inhale.

[0039] The atomizer 100 is arranged at the end of the first atomizer 200 away from the mouthpiece 31. The atomizer 100 includes a liquid storage tank 11, a liquid storage member 13, an atomizing core assembly 14, and a sealing member 12. An air outlet pipe 111 is provided in the liquid storage tank 11, one end of which is connected to the main sealing member 23 and the first air channel 221; the sealing member 12 is fixedly attached to the inner ring side wall of the liquid storage tank 11 and forms a sealed liquid storage cavity 112 with the liquid storage tank 11. An air inlet pipe 121 is provided on the sealing member 12, and the air inlet pipe 121 is connected to the outside air; the atomizing core assembly 14 is mounted between the air inlet pipe 121 and the air outlet pipe 111. The atomizing core assembly 14 is used to heat the atomizing matrix and atomize it into an aerosol. The atomizing core assembly 14 forms There is an atomization channel 144, the air inlet of the atomization channel 144 is connected to the air inlet pipe 121, and the air outlet of the atomization channel 144 is connected to the air outlet pipe 111; the liquid storage component 13 is arranged in the liquid storage cavity 112, and the liquid storage component 13 can be made of materials such as cotton core with liquid storage function. An exhaust channel 102 is provided between the liquid storage component 13 and the inner wall of the liquid storage tank 11, and a pressure relief channel 103 is provided between the liquid storage component 13 and the sealing component 12. The pressure relief channel 103 is connected to the air outlet of the atomization channel 144 through the exhaust channel 102. When the liquid storage member 13 expands at high temperature, the gas in the liquid storage chamber 112 can enter the atomizing channel 144 in sequence through the pressure relief channel 103 and the exhaust channel 102. The air inlet of the atomizing channel 144 is communicated with the outside air through the air inlet pipe 121, and the air outlet of the atomizing channel 144 is communicated with the outside air through the air outlet pipe 111 and the first air channel 221. The gas in the atomizing channel 144 can be discharged so that the air pressure in the liquid storage chamber 112 is balanced, thereby reducing the leakage of the atomized matrix. Of course, if the atomized matrix in the liquid storage chamber 112 is consumed and reduced during use, resulting in a decrease in the pressure in the liquid storage chamber 112, outside air can also enter the exhaust channel 102102 and the pressure relief channel 103 through the atomizing channel 144 to balance the internal air pressure of the liquid storage chamber 112.

[0040] The atomizing device also includes a battery 400, a circuit board (not shown in the figure) and an airflow sensor (not shown in the figure). The battery 400 is used to provide electrical energy for the atomizing device when it is working. The airflow sensor can be installed on the circuit board to facilitate modular assembly of components and improve production efficiency. The airflow sensor is configured to control the electrical connection between the atomizing core 40 and the battery 400 according to the user's suction action. Specifically, when the user inhales through the mouthpiece 31, the airflow sensor senses the change in airflow, and the airflow sensor controls the atomizing core 40 to be connected to the battery 400, and the atomizing core 40 can heat the atomizing matrix to generate an aerosol; when the user stops inhaling, the airflow sensor does not sense the change in airflow within a preset time, and the airflow sensor controls the atomizing core 40 to be disconnected from the battery 400, and the atomizing core 40 stops heating. Specifically, a microphone bracket 500 is provided in the shell 300, and the microphone bracket 500 is provided on the side of the seal 12 away from the atomization chamber. The circuit board and the airflow sensor are installed on the side of the microphone bracket 500 away from the seal 12. There is a gap between the microphone bracket 500 and the seal 12. A through hole is provided on the microphone bracket 500, and an air inlet hole 51 is provided on the shell 300. The outside air can enter the air inlet pipe 121 through the air inlet hole 51 of the shell 300 and the through hole of the microphone bracket 500, or the gas in the air inlet pipe 121 can be discharged into the outside air through the through hole on the microphone bracket 500 and the air inlet hole 51 on the shell 300.

[0041] See also Figure 2 In some embodiments, the atomizer core assembly 14 includes a first connector 141, a second connector 142, and a heating element 143. The first connector 141 and the second connector 142 form an atomization channel 144. The first connector 141 is arranged around the periphery of the outlet pipe 111, and the liquid storage member 13 is sleeved on the outer periphery of the first connector 141. A first gap 101 is formed between the first connector 141 and the outlet pipe 111. Optionally, the first connector 141 is made of a material with greater rigidity. For example, the first connector 141 can be a steel pipe. The liquid storage tank 11 and the outlet pipe 111 can be integrally formed. The liquid storage tank 11 and the outlet pipe 111 can be injection-molded with a high-temperature resistant hard plastic material. The first connector 141 is sleeved on the outer periphery of the outlet pipe 111 and a first gap 101 is formed between the inner wall of the first connector 141 and the outer wall of the outlet pipe 111. There is hard contact between the first connecting member 141 and the air outlet pipe 111, and the liquid storage member 13 is covered on the outside of the first connecting member 141. Even if the first connecting member 141 is squeezed by the liquid storage member 13, the first connecting member 141 itself has a large rigidity and can maintain its own shape to ensure that a first gap 101 is formed between the first connecting member 141 and the air outlet pipe 111 for airflow to pass through, and the exhaust channel 102 is connected to the atomization channel 144 through the first gap 101.

[0042] Similarly, the second connecting member 142 is arranged around the periphery of the air intake pipe 121, and the liquid storage member 13 is sleeved on the outer periphery of the second connecting member 142. The second connecting member 142 is also made of a steel pipe, and the air intake pipe 121 and the sealing member 12 are integrally formed. The air intake pipe 121 and the sealing member 12 are both made of silicone material to ensure the sealing effect.

[0043] Both ends of the heating element 143 are mounted on the first connecting member 141 and the second connecting member 142 respectively. Since the first connecting member 141 and the second connecting member 142 have a certain rigidity, they can support the heating element 143 .

[0044] See also Figure 2 as well as Figure 3 , Figure 3 yes Figure 1 Schematic diagram of the positional relationship between the liquid reservoir and the liquid storage tank in an embodiment. The exhaust channel 102 includes a first exhaust section 1021 that communicates with the pressure relief channel 103. The first exhaust section 1021 extends from the end face of the liquid reservoir 13 closest to the seal 12 toward the end face of the liquid reservoir 13 away from the seal 12 and penetrates the liquid reservoir 13. In other words, the first exhaust section 1021 extends axially along the atomization channel 144 and penetrates opposite sides of the liquid reservoir 13.

[0045] Alternatively, the first vent section 1021 may be a first groove 131 formed on the outer peripheral sidewall of the liquid storage element 13. One or more first grooves 131 may be provided. The first grooves 131 extend parallel to the axial direction of the atomization channel 144, and the opening of the first grooves 131 faces the inner sidewall of the liquid storage tank 11. In this manner, a gap is formed between the liquid storage element 13 and the inner sidewall of the liquid storage tank 11 to allow air to circulate.

[0046] See also Figure 2 as well as Figure 4 , Figure 4 Schematic diagram of the positional relationship between the liquid storage element and the liquid storage tank in another embodiment. Optionally, a first positioning member 113 is provided on the inner sidewall of the liquid storage tank 11. The first positioning member 113 contacts the liquid storage element 13 and separates the inner sidewall of the liquid storage tank 11 from the liquid storage element 13 to form a first vent section 1021 to allow air to circulate.

[0047] It can be understood that the first positioning member 113 and the first groove 131 can be set at the same time, and the first positioning member 113, the first groove 131 and the inner ring side wall of the liquid storage tank 11 together enclose the first exhaust section 1021 of the exhaust channel 102, so that the space of the first exhaust section 1021 can be larger, thereby making the gas flow smoother.

[0048] Please continue reading Figure 2The exhaust channel 102 also includes a second exhaust section 1022. Optionally, the second exhaust section 1022 extends radially along the atomization channel 144. One end of the second exhaust section 1022 is connected to the first gap 101, and the other end is connected to the first exhaust section 1021, that is, the pressure relief channel 103, the first exhaust section 1021, the second exhaust section 1022, the first gap 101 and the atomization channel 144 are connected in sequence.

[0049] Optionally, the second vent section 1022 may be a second groove (not shown) formed in the side wall of the liquid storage member 13 at the end away from the sealing member 12. One or more second grooves may be provided, extending perpendicularly to the axial direction of the atomization channel 144, and opening toward the inner top wall of the liquid storage tank 11. In this way, a gap is formed between the liquid storage member 13 and the inner top wall of the liquid storage tank 11 to allow air to circulate. One end of the second groove communicates with the first gap 101, and the other end communicates with the first vent section 1021.

[0050] Optionally, the inner top wall of the liquid storage bin 11 is provided with a second positioning member 114, which contacts the liquid storage member 13 and separates the inner top wall of the liquid storage bin 11 from the liquid storage member 13 to form a second exhaust section 1022 to allow air to circulate.

[0051] It is understandable that the second positioning member 114 and the second groove can be provided at the same time, and the second positioning member 114 , the second groove and the inner top wall of the liquid storage tank 11 together enclose the second exhaust section 1022 of the exhaust channel 102 .

[0052] The shapes of the first positioning member 113 and the second positioning member 114 can be plate-shaped, column-shaped, etc. This embodiment does not impose any specific restrictions on this, as long as the first positioning member 113 and the second positioning member 114 can separate the liquid storage member 13 from the inner wall of the liquid storage tank 11.

[0053] See also Figure 5 , Figure 5 yes Figure 1 Schematic diagram of the seal structure in an embodiment. The seal 12 includes a sealing portion 122 and a supporting rib 123. The sealing portion 122 is tightly attached to the inner ring sidewall of the liquid storage tank 11. The supporting rib 123 is disposed on the side of the sealing portion 122 adjacent to the liquid storage member 13. The supporting rib 123 is used to support the liquid storage member 13 and separate the sealing portion 122 from the liquid storage member 13, thereby forming a pressure relief channel 103 between the sealing portion 122 and the liquid storage member 13. The planar height of the supporting rib 123 is higher than that of the sealing portion 122, so that the supporting rib 123 can support the liquid storage member 13 and separate the liquid storage member 13 from the sealing portion 122.

[0054] See also Figure 2 as well as Figure 5In some embodiments, the supporting ridge 123 includes a main support bar 1231, which is disposed on the side of the sealing portion 122 facing the liquid storage element 13. The main support bar 1231 surrounds the edge of the sealing portion 122. The inner periphery of the main support bar 1231, the sealing portion 122, the atomization channel 144, and the liquid storage element 13 together form an inner annular channel 1031. The outer periphery of the main support bar 1231 is provided with a chamfered structure 12311, forming an outer annular channel 1032 between the main support bar 1231 and the inner annular sidewall of the liquid storage chamber 11. The inner and outer annular channels 1031 and 1032 together form the pressure relief channel 103, and the inner and outer annular channels 1031 and 1032 are respectively connected to the exhaust channel 102. The main support bar 1231 can support the liquid storage element 13. By arranging the main support bar 1231 close to the edge of the sealing portion 122, the edge of the liquid storage element 13 can be better supported. Furthermore, by providing chamfered structures 12311 on the outer periphery of the main support bars 1231 to form an outer annular channel 1032, air can circulate within the outer annular channel 1032, facilitating the convergence of air between the sealing member 12 and the liquid storage member 13 and its flow to the location of the exhaust channel 102. It is understood that the closer the liquid storage member 13 is to the support position, the greater the supporting force it receives, and the smaller the deformation of the liquid storage member 13 due to high-temperature expansion. The outer annular channel 1032, supported by the main support bars 1231 and the sidewalls of the liquid storage member 13, effectively prevents the liquid storage member 13 from blocking the pressure relief channel 103 after expansion, thereby ensuring air circulation between the exhaust channel 102 and the pressure relief channel 103.

[0055] Please combine Figure 4 as well as Figure 6 , Figure 6 Schematic diagram of the connection between the sealing member and the liquid storage tank in another embodiment. Furthermore, a notch 12312 is provided on the main support bar 1231. The notch 12312 penetrates the main support bar 1231 in the radial direction of the main support bar 1231. The depth of the notch 12312 is the same as the depth of the chamfer structure 12311. By providing the notch 12312, the inner ring channel 1031 and the outer ring channel 1032 can be connected. In this way, even if part of the space in the inner ring channel 1031 is blocked by the expanded liquid storage member 13, the gas in the blocked space can enter the outer ring channel 1032 through the notch 12312 and converge along the outer ring channel 1032 to the position of the exhaust channel 102. Figure 6 The airflow path P indicated by the dashed arrow is the path for the gas in the inner ring channel 1031 to circulate through the notch 12312 and then enter the outer ring channel 1032. Optionally, a plurality of notches 12312 may be provided at intervals around the main support bar 1231.

[0056] The supporting ridge 123 also includes a plurality of sub-support bars 1232. Each sub-support bar 1232 is an open structure and is spaced apart within the inner annular channel 1031. The sub-support bars 1232 can further limit the deformation of the liquid storage element 13 in the inner annular channel 1031 when it expands, thereby preventing the liquid storage element 13 from partially blocking the inner annular channel 1031 when it expands. In this embodiment, the sub-support bars 1232 can be open structures such as arc blocks, strips, etc. Figure 5 Optionally, the sub-support bar 1232 can surround the air inlet pipe 121 and be spaced apart from the air inlet pipe 121, and a notch 12321 is provided on the sub-support bar 1232 to facilitate air circulation at the notch 12321; Optionally, the sub-support bar 1232 can surround the air inlet pipe 121 and be tightly attached to the air inlet pipe 121, and a notch 12321 is provided on the sub-support bar 1232, and a pin groove 1211 is provided on the air inlet pipe 121, and a pin hole 1221 is further provided on the sealing portion 122, so that the pins of the heating element 143 can be The pin slot 1211, notch 12321, and pin hole 1221 are connected to the circuit board. It should be noted that the pin hole 1221 is sealed after the pins of the atomizer core 40 are connected to the circuit board, so the pin hole 1221 is not ventilated to the outside air. Optionally, the sub-support bar 1232 is in the shape of a straight strip, and the ends of the sub-support bar 1232 maintain a certain distance from the inner side wall of the main support bar 1231 to prevent the sub-support bar 1232 and the main support bar 1231 from forming a closed structure. It is understandable that the shapes of the multiple sub-support bars 1232 can be different or the same.

[0057] Please continue reading Figure 5 In some embodiments, the sealing member 12 further includes a resistance portion 124, which is disposed on the outer periphery of the sealing member 122. A step structure is formed between the resistance portion 124 and the sealing member 122.
