For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or components inherent to these processes, methods, products or devices.

[0035] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0036] See also Figure 1 as well as Figure 2 , Figure 1 is a schematic diagram of the internal structure of the atomization device in some embodiments of the present application, Figure 2 yes Figure 1 Schematic diagram of the explosion of the atomizing device in the embodiment. The embodiment of the present application provides an atomizing device, comprising a shell 70, a power supply assembly 60 and an atomizer. A suction nozzle 71 is provided on the shell 70, and the suction nozzle 71 can be used for the user to inhale. The suction nozzle 71 and the shell 70 can be an integrated structure to improve the integrity of the atomizing device; the suction nozzle 71 and the shell 70 can also be a split structure, and the suction nozzle 71 and the shell 70 are detachably fixedly connected, and the outside of the suction nozzle 71 is coated with an antibacterial layer to ensure the safety of the user and during inhalation. The atomizer is arranged in the shell 70, and the power supply assembly 60 includes a battery 61, which is electrically connected to the atomizer and is used to provide the atomizer with electrical energy during operation.

[0037] The atomizer includes a liquid storage tank 10, an atomization core assembly 20 and a first sealing member 30, wherein the liquid storage tank 10 has an opening at one end near the suction nozzle 71, and a liquid storage member 18 is arranged in the liquid storage tank 10. The liquid storage member 18 is used to store the atomization matrix. The liquid storage member 18 is made of materials such as a cotton core with a liquid storage function, and an exhaust channel 15 is formed between the liquid storage member 18 and the liquid storage tank 10; an atomization channel 11 is formed in the liquid storage member 18, and the atomization core assembly 20 is arranged in the atomization channel 11; the first sealing member 30 blocks the opening of the liquid storage tank 10 and encloses the liquid storage chamber 12 with the liquid storage tank 10, and an accommodating chamber 13 and a pressure relief channel 14 are formed between the liquid storage member 18 and the first sealing member 30. When the liquid storage member 18 expands, it can be squeezed into the accommodating chamber 13, and the exhaust channel 15, the pressure relief channel 14 and the air outlet of the atomization channel 11 are connected in sequence.

[0038] By adopting the above solution, an exhaust channel 15 is provided between the liquid storage member 18 and the liquid storage tank 10, and a pressure relief channel 14 is provided between the liquid storage member 18 and the first sealing member 30. The exhaust channel 15, the pressure relief channel 14 and the atomization channel 11 are connected in sequence to form a gas exchange channel. Figure 1 The direction indicated by the arrow is the path of the gas exchange channel. When the gas in the atomizing device expands due to heat, it can be quickly discharged through the exhaust channel 15, the pressure relief channel 14 and the atomizing channel 11 to prevent the gas expansion from squeezing the liquid storage part 18 and causing leakage. By reserving a accommodating chamber 13 between the first sealing member 30 and the liquid storage part 18, the liquid storage part 18 has an expandable space, further reducing the squeezing force on the liquid storage part 18 under high temperature conditions, and preventing the atomized matrix from leaking out of the liquid storage part 18. At the same time, when the air pressure in the liquid storage chamber 12 decreases, the outside air can also enter the liquid storage chamber 12 through the atomizing channel 11 to balance the internal air pressure of the liquid storage chamber 12.

[0039] See also Figure 3 as well as Figure 4 , Figure 3 yes Figure 1 Schematic diagram of the cooperation relationship between the first sealing member and the liquid storage tank in the embodiment, Figure 4 yes Figure 1 Schematic diagram of another embodiment of the first sealing member and the liquid storage tank. In some embodiments, the first sealing member 30 includes a sealing portion 31 and a supporting portion 32. The sealing portion 31 is fixedly attached to the inner sidewall of the liquid storage tank 10 and defines the air outlet of the atomization channel 11. The supporting portion 32 is located on the side of the sealing portion 31 facing the liquid storage member 18. The supporting portion 32 separates the sealing portion 31 and the liquid storage member 18 to form the accommodating chamber 13 and the pressure relief channel 14.

[0040] Please combine Figure 1 as well as Figure 3Specifically, the support portion 32 includes a first support bar 321 and a second support bar 322. The first support bar 321 is disposed around the edge of the sealing portion 31, and the second support bar 322 is disposed around the periphery of the atomization channel 11. The opposing sides of the first and second support bars 321, 322, and the opposing sides of the sealing portion 31 and the liquid storage member 18 enclose a receiving chamber 13. With the first and second support bars 321, 322 supported between the sealing portion 31 and the liquid storage member 18, a sufficiently large receiving chamber 13 can be enclosed. Even if the liquid storage member 18 expands due to heat, at least a portion of the liquid storage member 18 can deform freely and enter the receiving chamber 13, avoiding direct compression by the first sealing member 30.

[0041] The first support bar 321 is provided with a first notch 33, and the second support bar 322 is provided with a second notch 34. The first notch 33, the accommodating cavity 13, and the second notch 34 are sequentially connected to form the pressure relief channel 14. The first notch 33 and the second notch 34 are arranged opposite each other. Multiple first notches 33 and second notches 34 can be arranged in an array along the circumference of the atomization channel 11 to ensure that gas can quickly pass through the pressure relief channel 14 and be discharged.

[0042] Optionally, a stiffening rib 323 is further provided between the second support bar 322 and the sealing portion 31, and the stiffening rib 323 may be wedge-shaped or triangular. The first sealing member 30 is made of a material such as silicone with good compressibility. The stiffening rib 323 is provided to enhance the strength of the second support bar 322 and reduce the deformation of the first support portion 32 when it is squeezed. At the same time, the stiffening rib 323 may be located inside the accommodating cavity 13, and the stiffening rib 323 may separate the sealing portion 31 and the liquid storage member 18 inside the accommodating cavity 13. It should be noted that the stiffening rib 323 is not connected to the first support bar 321. In this way, on the one hand, the volume of the stiffening rib 323 can be reduced to avoid occupying the internal space of the accommodating cavity 13. On the other hand, the stiffening rib 323 is prevented from being connected to the first support bar 321 and the second support bar 322 to form a closed annular structure, which causes the gas to be blocked in the annular structure and unable to be discharged.

[0043] Optionally, a chamfered structure 35 is provided on the outer periphery of the first support bar 321, forming an annular gap between the first support bar 321 and the inner annular sidewall of the liquid storage tank 10. The annular gap is connected to the exhaust channel 15 and is connected to the accommodating chamber 13 through the first notch 33. In other words, the pressure relief channel 14 includes an annular gap, a first notch 33, an accommodating chamber 13, and a second notch 34. The first support bar 321 can support the liquid storage member 18. By positioning the first support bar 321 near the edge of the sealing portion 31, a better support effect can be provided for the edge of the liquid storage member 18. Furthermore, by providing the chamfered structure 35 on the outer periphery of the first support bar 321 to form an annular gap, air can circulate in the annular gap, facilitating the air in the exhaust channel 15 to converge and flow to the location of the first notch 33 and then pass through the first notch 33, the accommodating chamber 13, and the second notch 34 to reach the air outlet of the atomizer for discharge. It can be understood that the closer to the support position, the greater the support force on the liquid storage component 18, and the smaller the deformation of the liquid storage component 18 due to high-temperature expansion. The liquid storage component 18 is supported by the first support bar 321 and the side wall of the liquid storage component 18 around the annular gap, which can effectively prevent the liquid storage component 18 from blocking the pressure relief channel 14 after expansion, thereby ensuring air circulation between the exhaust channel 15 and the pressure relief channel 14.

[0044] It can be understood that the support portion 32 is not limited to the first support bar 321 and the second support bar 322 mentioned above. For example, the support portion 32 can be a plurality of linear protrusions, arc-shaped protrusions or other special-shaped structures arranged in a circumferential array along the atomization channel 11. As long as the support portion 32 ensures that the exhaust channel 15 connected to the atomization channel 11 is formed, a sufficiently large accommodating chamber 13 is formed between the sealing portion 31 and the liquid storage component 18, the accommodating chamber 13 and the pressure relief channel 14 can be independent of each other, or at least partially overlap.

[0045] Please continue reading Figure 1 as well as Figure 5 , Figure 5 yes Figure 1 Schematic diagram of the partial structure of the liquid storage tank in the embodiment. In some embodiments, the liquid storage tank 10 includes a base 16 and a tank body 17 arranged around the side of the base 16. The base 16 and the tank body 17 are made of hard plastic material and are integrally formed, eliminating the need for additional seals to seal the tank body 17 of the liquid storage tank 10. This can simplify the structure and reduce costs. The integrally formed base 16 and tank body 17 can also ensure the overall sealing performance of the liquid storage tank 10, making the structure more reliable. The inner wall of the tank body 17 is the inner ring side wall of the liquid storage tank 10. The exhaust channel 15 includes a first exhaust groove 151 and a second exhaust groove 152.

[0046] The first exhaust groove 151 is disposed between the base 16 and the liquid storage member 18 , and the first exhaust groove 151 extends perpendicularly to the length direction of the atomizer. Figure 1The Y direction is the length direction of the atomizer, and the X direction is the width direction of the atomizer.

[0047] In some scenarios, a plurality of main ridges 161 are provided on the side of the base 16 facing the liquid storage component 18. Each main ridge 161 is arranged on the peripheral side of the atomization channel 11, and each main ridge 161 is respectively enclosed with the warehouse body and the base to form a liquid collecting groove 162. Two adjacent main ridges 161 are spaced apart to form a first exhaust groove 151. Specifically, the main ridge 161 includes a first ridge segment 1611 and two second ridge segments 1612 respectively extending from the two ends of the first ridge segment 1611. The two second ridge segments 1612 can extend radially along the atomization channel 11. The first ridge segment 1611 is close to the outer edge of the atomization channel 11 and is arranged on the peripheral side of the atomization channel 11. The end of each second ridge segment 1612 away from the first ridge segment 1611 is connected to the warehouse body 17, so that each main ridge 161 is connected to the warehouse body 17 to form a closed annular structure, and is enclosed with the base 16 to form a liquid collecting tank 162. The liquid collecting tank 162 can collect the atomized matrix that is condensed or squeezed out of the liquid storage component 18. When the part of the atomized matrix in the liquid storage component 18 is squeezed out due to extreme conditions, it can be temporarily stored in the liquid collecting tank 162. After the conditions return to normal, the atomized matrix can be adsorbed by the liquid storage component 18 again. The second rib sections 1612 of two adjacent main ribs 161 are spaced apart to form first venting grooves 151. In this embodiment, four main ribs 161 are provided, arranged in a cross pattern, and are located between the plurality of liquid collecting grooves 162. The plurality of main ribs 161 are integrally injection-molded with the base 16 and the liquid storage tank 10. That is, the main ribs 161 are also made of a hard plastic material. This makes the liquid collecting grooves 162 and the first venting grooves 151 less susceptible to deformation, facilitating processing while ensuring the structural reliability of the first venting grooves 151.

[0048] Optionally, the side of the base 16 facing the liquid storage member 18 is further provided with a plurality of sub-ridges 167. The sub-ridges 167 are located within the liquid collection groove 162. The sub-ridges 167 can separate the liquid collection groove 162 into a plurality of mutually disconnected liquid collection areas. This ensures that when a portion of the liquid storage member 18 expands and is squeezed, the atomized matrix that leaks out can be collected in the corresponding liquid collection area. After the liquid storage member 18 recovers its shape, the portion of the region that leaked the atomized matrix can reabsorb the atomized matrix in the corresponding liquid collection area, ensuring that the atomized matrix adsorbed on the liquid storage member 18 is evenly distributed.

[0049] In some scenarios, the first exhaust groove 151 is provided on the side of the liquid storage member 18 facing the base 16. The first exhaust groove 151 extends perpendicular to the length of the atomizer. For example, the first exhaust groove extends radially along the atomization channel. One or more first exhaust grooves 151 may be provided, and the opening direction of the first exhaust groove 151 faces the base 16. In this way, a gap is formed between the liquid storage member 18 and the base 16 of the liquid storage tank 10 to allow air to circulate.

[0050] The second exhaust groove 152 is provided between the chamber body 17 and the liquid storage member 18 . The second exhaust groove 152 extends along the length of the atomizer and passes through the liquid storage member 18 . The second exhaust groove 152 communicates with the first exhaust groove 151 and the pressure relief channel 14 .

[0051] In some scenarios, the second venting grooves 152 can be provided on the outer peripheral sidewall of the liquid storage member 18. One or more second venting grooves 152 can be provided. The second venting grooves 152 extend parallel to the length of the atomizer, and the openings of the second venting grooves 152 face the inner sidewall of the liquid storage tank 10. In this way, a gap is formed between the liquid storage member 18 and the tank body 17 of the liquid storage tank 10 to allow air to circulate.

[0052] In some scenarios, the second vent groove 152 can be opened on the inner side wall of the liquid storage tank 10. There can be one or more second vent grooves 152. The extension direction of the second vent groove 152 is parallel to the axial direction of the atomization channel 11, and the opening direction of the second vent groove 152 is toward the liquid storage member 18. In this way, a gap is formed between the liquid storage member 18 and the tank body 17 of the liquid storage tank 10 to allow air to circulate.

[0053] See also Figure 2 as well as Figure 5 In some embodiments, the atomizer core assembly 20 includes a connecting tube 22 and a heating element 21. The heating element 21 is used to heat the atomization matrix and form an aerosol. The heating element 21 is installed between the connecting tubes 22, and at least part of the atomization channel 11 is enclosed by the connecting tube 22. The connecting tube 22 can be a fiberglass tube or a steel tube. The connecting tube 22 has a large hardness and can support the heating element 21 and install the heating element 21 in the liquid storage tank 10. An airway tube 166 is provided on the side of the base 16 facing the liquid storage member 18. The connecting tube 22 is directly sleeved on the outer periphery of the airway tube 166 to facilitate the assembly connection between the atomizer core assembly 20 and the liquid storage tank 10.

[0054] See also Figure 1 as well as Figure 2Optionally, the atomization channel 11 includes a first atomization section 111 and a second atomization section 112. The connecting tube 22 is arranged in the first atomization section 111 and contacts the liquid storage member 18. The aerosol passes through the first atomization section 111 and the second atomization section 112 in sequence and then reaches the position of the suction nozzle 71 to be inhaled by the user. It can be understood that since the connecting tube 22 has a large hardness and is not easy to deform, the liquid storage member 18 in the first atomization section 111 is easily squeezed by the connecting tube 22 when it expands at high temperature, resulting in leakage of the atomized matrix; and the second atomization section 112 is formed by the liquid storage member 18 itself. The liquid storage member 18 can expand and deform in the space of the second atomization section 112 at high temperature, reducing the area of ​​the liquid storage member 18 squeezed, reducing the squeezing force on the liquid storage member 18, and thus reducing the amount of atomized matrix that leaks when the liquid storage member 18 is squeezed.

[0055] Optionally, the length of the connecting tube 22 is adapted to the length of the atomization channel 11, and the connecting tube 22 directly abuts against the sealing portion 31 of the first sealing member 30 to ensure a good sealing effect. Of course, in order to achieve the connection between the pressure relief channel 14 and the atomization channel 11, a through hole can be opened in the connecting tube 22 at a position corresponding to the second notch 34, and the second notch 34 is connected to the atomization channel 11 through the through hole.

[0056] See also Figure 2 as well as Figure 6 , Figure 6 yes Figure 1 Schematic diagram of the cooperation relationship between the liquid storage tank and the second sealing member in the embodiment. In some embodiments, the atomizer further includes a second sealing member 40, and a receiving groove 1631 is provided on the side of the base 16 facing away from the liquid storage chamber 12. The second sealing member 40 is sealed in the receiving groove 1631 and enclosed with the base 16 to form an air chamber 41, and the air chamber 41 is connected to the atomization channel 11. The second sealing member 40 is provided with an air inlet channel 42, one end of the air inlet channel 42 is connected to the external gas, and the other end is connected to the air chamber 41. Optionally, the air inlet channel 42 is coaxially arranged with the atomization channel 11 to shorten the length of the air inlet channel 42 and reduce air resistance, so that the gas can quickly reach the atomization channel 11 from the air inlet channel 42 to meet the air supply needs of the user when inhaling.

[0057] See also Figure 7 , Figure 7 yes Figure 1 Schematic diagram of the structure of the second sealing member in an embodiment. In some embodiments, the second sealing member 40 includes a sensing channel 43, which is connected to the atomization channel 11 through the air chamber 41. The sensing channel 43 is offset from the atomization channel 11. An airflow sensor 51 is disposed within the sensing channel 43. The airflow sensor 51 is configured to respond to changes in the air pressure signal of the sensing channel 43 and output an electrical signal to the atomizer.

[0058] Specifically, the airflow sensor 51 is configured to control the electrical connection between the atomizer and the battery 61 according to the user's suction action. When the user inhales, the airflow sensor 51 senses the change in airflow, and the airflow sensor 51 controls the connection between the atomizer and the battery 61, so that the atomizer can heat the atomization matrix to generate an aerosol. When the user stops inhaling, the airflow sensor 51 does not sense the change in airflow within a preset time period, and the airflow sensor 51 controls the disconnection between the atomizer and the battery 61, so that the atomizer stops heating. The misalignment between the sensing channel 43 and the atomization channel 11 can prevent the condensate in the atomization channel 11 from directly flowing back into the sensing channel 43, thereby reducing the risk of failure of the airflow sensor 51. At the same time, the airflow sensor 51 is arranged in the second sealing member 40, and the second sealing member 40 can isolate and protect the airflow sensor 51 to prevent the airflow sensor 51 from being damaged by hard contact with other parts.

[0059] See also Figure 8 , Figure 8 yes Figure 1 Schematic diagram of the structure of the liquid storage tank in the embodiment. In some embodiments, the base 16 includes a bottom plate and a partition 165, the partition 165 is connected to form a closed annular structure, the partition 165 separates the bottom plate to form a first mounting area 163 and a second mounting area 164, and the first mounting area 163 and the partition 165 are enclosed to form a receiving groove 1631. The projection of the atomization channel 11 and the second sealing member 40 on the first plane is located in the first mounting area 163, and the first plane is perpendicular to the axial reference plane of the atomization channel 11. In other words, the second sealing member 40 does not need to be fitted with the inner wall of the entire warehouse body 17, but only needs to be adapted to the contour of the first mounting area 163, so that the volume of the second sealing member 40 can be reduced and the internal space of the atomization device can be optimized.

[0060] See also Figure 2 as well as Figure 9 , Figure 9 yes Figure 1 Schematic diagram of the mating relationship between the power supply assembly and the circuit board in an embodiment. In some embodiments, the atomizer further includes a circuit board 50, to which the airflow sensor 51 is fixed and mounted within the receiving slot. The second mounting area 164 defines a pin hole 1641, through which the heating element 21 passes a wire to establish an electrical connection with the circuit board 50. After the wire is inserted, the pin hole 1641 can be sealed with glue to prevent leakage of the atomized matrix from the pin hole 1641.

[0061] Optionally, the wires are directly welded on the circuit board 50 to achieve electrical connection between the circuit board 50 and the atomizer core assembly 20 .

[0062] Optionally, after passing through the pin hole 1641, the wire is connected to the terminal. The terminal can be a conductive spring familiar to those skilled in the art. The circuit board 50 is electrically connected to the terminal through the conductive post 52. The conductive post 52 is arranged on the side of the circuit board 50 facing the base 16. The terminal can be arranged in the pin hole 1641. The conductive post 52 is directly plugged into the pin hole 1641 and abuts against the terminal. The terminal can also be arranged outside the pin hole 1641 to facilitate the packaging of the pin hole 1641. For example, the second mounting area 164 is provided with a positioning hole 1642, the terminal is arranged in the positioning hole 1642, the conductive post 52 is inserted into the positioning hole 1642, and the conductive post 52 abuts against the terminal.

[0063] In this embodiment, the second mounting area 164 forms an assembly space for the circuit board 50 and the atomizer core assembly 20, making full use of the internal space in the width direction of the atomizer device to optimize the internal space of the atomizer device, making each component more compact and reducing space occupation.

[0064] The circuit board 50 is arranged between the power supply assembly 60 and the liquid storage tank 10. The power supply assembly 60 is detachably fixedly connected to the housing 70, and specifically can be a detachable fixed connection structure familiar to those skilled in the art, such as bolt fixing or snap fixing. The circuit board 50 abuts the liquid storage tank 10 and the power supply assembly 60. The airflow sensor 51 on the circuit board 50 is adapted to the inner diameter of the sensing channel 43. During assembly, the airflow sensor 51 is directly inserted into the sensing channel 43 and fixedly fits with the inner wall of the sensing channel 43, so that the sensing end of the airflow sensor 51 is blocked in the sensing channel 43, so that the airflow sensor 51 can sense the airflow changes in the air chamber 41 and control the on and off of the atomizer and the power supply assembly 60. The opposite sides of the circuit board 50 abut the liquid storage tank 10 and the power supply assembly 60 respectively. Therefore, it is only necessary to fix the relative position of the power supply assembly 60 and the liquid storage tank 10 to achieve the fixation of the circuit board 50. Optionally, the power supply assembly 60 further includes a housing 62, which is snap-fastened to the housing 70, thereby encapsulating and fixing the circuit board 50 and the liquid storage tank 10 to the housing 70, while preventing the power supply assembly 60 and the atomizer from being separated from the housing 70. In addition, a limiting groove 53 is provided on the circuit board 50, and the power supply assembly 60 further includes a limiting post 63, which is fixedly connected to the housing 62 and is disposed in the limiting groove 53 to limit the circuit board 50.
