Description

Technical Field

[0001] The present application relates to the field of electronic atomization technology, and in particular to an atomization device. Background Art

[0002] Atomizers heat and atomize aerosols to produce aerosols. With technological advancements and the need for intelligent control, atomizers often use airflow sensors to control their operation. Generally speaking, when a user inhales, the airflow sensor responds to changes in airflow and generates an electrical signal. This signal triggers a control circuit, which in turn controls the operation of the atomizer. When the user stops inhaling, the airflow signal disappears, and the control circuit stops the atomizer.

[0003] However, traditional airflow sensors are usually connected to circuit boards by welding wires, resulting in low product space utilization, increased costs, and complex assembly. Utility Model Content

DETAILED DESCRIPTION

[0032] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0033] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various implementations, and the operational steps involved in each embodiment may be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a particular embodiment and do not imply a required composition and / or sequence.

[0034] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0035] In related technologies, the atomization device is controlled to open and close through an airflow sensor. The airflow sensor is usually connected to the circuit board by welding wires. The solder pads of the wiring harness cause the product cost to increase. At the same time, the wiring harness occupies space inside the product, resulting in low product space utilization and complex product assembly.

[0036] In response to the above problems, the present application provides an atomization device to fix the airflow sensor on one side of the control circuit board, so that the airflow sensor and the control circuit board form an integrated structure. Compared with the connection method of wire harness welding used in related technologies, it can effectively reduce product costs, reduce the internal space occupied by the product, improve space utilization, and further reduce product assembly steps and improve assembly efficiency.

[0037] The present application provides an atomizer device comprising a sensing component and an atomizer, wherein an airflow sensor in the sensing component is capable of providing an on / off signal to the atomizer. Specifically, the atomizer device is provided with an air inlet connected to the outside atmosphere. The user allows outside air to enter by suction, and the airflow sensor senses the change in airflow and generates a corresponding control signal, which is then used to control the operation of the atomizer. When the user stops suctioning, preventing outside air from entering, the airflow sensor is unable to sense the change in airflow, and the control signal disappears, causing the atomizer to stop operating.

[0038] See also Figures 1-8 As shown, in one embodiment, an atomization device 200 includes a second air inlet 72 , a sensing component 100 and an atomizer 80 . The sensing component 100 includes a control circuit board 10 , an airflow sensor 20 and a sensor bracket 30 .

[0039] The airflow sensor 20 is fixed to one side of the control circuit board 10, so that the control circuit board 10 and the airflow sensor 20 form an integrated structure, and the airflow sensor 20 is electrically connected to the control circuit board 10. In a specific embodiment, the airflow sensor 20 is electrically connected to the input end of the control circuit board 10, and the output end of the control circuit board 10 is electrically connected to the airflow sensor 20. The airflow sensor 20 can generate an air pressure signal based on changes in air pressure, and the control circuit board 10 can convert the air pressure signal into a control signal for controlling the activation of the atomizer 80.

[0040] In this embodiment, a welding position can be provided on one side of the control circuit board 10, and the airflow sensor 20 is welded to the welding position of the control circuit board 10, thereby forming an integrated structure with the control circuit board 20. Compared with the related art method of using wire harness welding connection, this can reduce the material cost and thus reduce the production cost of this product. At the same time, after the airflow sensor 20 and the control circuit board 10 are fixed in an integrated structure, the layout space of the airflow sensor 20 can be reduced, and the internal space utilization of the product can be improved. Furthermore, the operator can assemble the airflow sensor 20 simply by installing the control circuit board 10, thereby reducing the assembly steps and improving the product assembly efficiency.

[0041] In one embodiment, the airflow sensor 20 is mounted on the control circuit board 10 through surface mount technology (SMT). During mass production, the airflow sensor 20 is easy to obtain and easy to test before assembly. At the same time, it can also meet the needs of different version improvements in the future.

[0042] like Figure 2-Figure 4 As shown, the sensor bracket 30 is provided with an insertion slot 31, and the side wall of the insertion slot 31 is provided with a connecting hole 32 and a mounting hole 33, see Figure 6-Figure 8 As shown, the insertion slot 31 is used to seal the atomizer 80, and the airflow sensor 20 is installed in the mounting hole 33. The airflow sensor 20 is in fluid communication with the communication hole 32 through the mounting hole 33, and the atomizer 80 is in fluid communication with the second air inlet hole 72 through the communication hole 32. It should be noted that the communication between the atomizer 80 and the second air inlet hole 72 is fluid communication, that is, the external air can enter the atomizer 80 through the second air inlet hole 72 and the communication hole 32 in sequence.

[0043] In this embodiment, since the atomizer 80 can be connected to the external atmosphere through the connecting hole 32 and the second air inlet 72, the external atmosphere can enter the insertion slot 31 through the connecting hole 32, and as the external atmosphere flows, a negative pressure is formed in the mounting hole 33. The airflow sensor 20 can sense the change in air pressure and generate a corresponding control signal to start the atomizer 80.

[0044] Therefore, it can be understood that fluid communication refers to the ability to effectively trigger the gas flow sensed by the airflow sensor 20, thereby triggering the airflow sensor 20 to sense the air pressure change.

[0045] In actual use, when a user inhales the atomizer 80, external air enters the insertion slot 31 through the second air inlet 72 and the communication hole 32, and then enters the interior of the atomizer 80 through the insertion slot 31. The external air forms an airflow in the insertion slot 31, causing a certain negative pressure to be generated in the mounting hole 33. The airflow sensor 20 installed in the mounting hole 33 can sense the air pressure change, thereby generating an air pressure signal. Under the action of the control circuit board 10, this air pressure signal is converted into a control signal for controlling the activation of the atomizer 80. The control circuit board 10 transmits this control signal to the atomizer 80 to control the operation of the atomizer 80. When the user stops inhaling, the airflow sensor 20 cannot sense the air pressure change, and the control circuit board 10 controls the atomizer 80 to stop operating.

[0046] The setting of the sensor bracket 30 can connect the airflow sensor 20 with the connecting hole 32 through the mounting hole 33, and the atomizer 80 installed in the insertion slot 31 can be connected to the external atmosphere through the connecting hole 32. Therefore, the sensor bracket 30 can achieve air path connection while installing the atomizer 80 and the airflow sensor 20, saving air path layout space and making the product layout more compact.

[0047] Combine Figure 6-Figure 8 as well as Figure 12 As shown, in this embodiment, the atomizing device 200 includes at least two atomizers 80, and the airflow sensor 20 is in fluid communication with at least one of the atomizers 80 to activate the operation of at least one of the atomizers 80. Of course, in other embodiments, the airflow sensor 20 can be in fluid communication with each atomizer 80 so that each atomizer 80 can be activated and operated synchronously.

[0048] In one embodiment, if Figure 2 and Figure 8 As shown, the atomization device 200 also includes at least one pneumatic switch 20', which is in fluid communication with at least one of the atomizers 80. Furthermore, each atomizer 80 is in fluid communication with only one of the airflow sensor 20 and the pneumatic switch 20'. In other words, one atomizer 80 can be in fluid communication with the airflow sensor 20, while the remaining atomizers 80 are in fluid communication with the pneumatic switch 20'. In this way, each atomizer 80 can be independently controlled to operate independently. The pneumatic switch 20' has the same function as the airflow sensor 20: both generate an air pressure signal when the air pressure changes, and convert the air pressure signal into a start signal for controlling the operation of the atomizer 80 in fluid communication with the pneumatic switch 20' via the control circuit board.

[0049] Of course, in this embodiment, the pneumatic switch 20 ′ and the airflow sensor 80 may have the same structure, or they may be different, but both can generate corresponding air pressure signals when the air pressure changes.

[0050] In one embodiment, the atomizer 80 includes a liquid storage mechanism 81 and an atomizer core 82. The liquid storage mechanism 81 includes a chamber body 811 and a bottom cover 812. The chamber body 811 has an opening at the bottom. The bottom cover 812 is sealed to the opening at the bottom of the chamber body 811, so that the chamber body 811 and the bottom cover 812 enclose a liquid storage chamber 810. A liquid storage member 813 is provided inside the liquid storage chamber 810. An atomization channel 814 is provided inside the liquid storage member 813. The atomizer core 82 is installed in the atomization channel 814. The bottom cover 812 is also provided with an insertion portion 815. The insertion portion 815 is further provided with a first air inlet 816 that is connected to the atomizer core 82. The insertion portion 815 is inserted into the insertion slot 31, so that the first air inlet 816 is connected to the insertion slot 31.

[0051] The liquid storage member 813 is used to store the atomized matrix and can transfer the stored atomized matrix to the atomizing core 82 . The atomizing core 82 can heat the atomized matrix stored in the liquid storage member 813 to atomize and generate aerosol, and the aerosol can be output along the atomizing channel 814 .

[0052] In one embodiment, the atomizer 80 is installed inside the shell 70, wherein one end of the atomization channel 814 passes through the warehouse body 811 of the liquid storage mechanism 81. In some embodiments, in order to facilitate the user to inhale, a suction nozzle 71 is further provided on the shell 70, and the suction nozzle 71 is provided with a suction nozzle channel 711. The suction nozzle channel 711 is connected to one end of the atomization channel 814 that passes through the warehouse body 811. The user inhales through the suction nozzle 71, and the external atmosphere flows in the direction of the second air inlet 72, the connecting hole 32, the insertion slot 31, the first air inlet 816, and the atomization channel 814 in sequence. When the atomization core 82 heats the atomization matrix to generate aerosol, the aerosol is output in the direction of the atomization channel 814 and the suction nozzle channel 711 in sequence.

[0053] like Figure 6-Figure 8 ,as well as Figure 12 and Figure 13 As shown, in this embodiment, at least two liquid storage members 813 are provided inside the liquid storage chamber 810. The at least two liquid storage members 813 are relatively independent and can store the same type or different types of atomized matrices. Each liquid storage member 813 is provided with an atomization channel 814, and the atomization channels 814 in each liquid storage member 813 are connected to the nozzle channel 711 of the suction nozzle 71. At the same time, an atomization core 82 is provided in each atomization channel 814. At least two atomization cores 82 can work simultaneously or at different times, or a fixed atomization core 82 can be in a working state all the time, and the remaining atomization cores 82 can work selectively, and the specific selection is made according to actual needs.

[0054] Continue to see Figure 12 As shown, the atomizing core 82 includes an atomizing tube 821, a liquid guide 822 and a heating element 823, wherein the atomizing tube 821 is arranged inside the atomizing channel 814, part of the liquid guide 822 is installed inside the atomizing tube 821, and the remaining part of the liquid guide 822 extends to the outside of the atomizing tube 821 to contact the liquid storage part 813 for easy liquid conduction, and the heating element 823 is arranged inside the liquid guide 822. The heating element 823 is preferably a mesh heating wire structure and is arranged in a circumferential manner in the inner cavity of the liquid guide 822 so as to circumferentially heat the atomized matrix introduced into the liquid guide 822. In some embodiments, the heating element 823 can also be a heating sheet, a threaded heating wire, a silk-screen heating pattern, etc.

[0055] In one embodiment, two heaters 823 are provided in one atomizer core 82, and one heater 823 is provided in the other atomizer core 82. The capacity of the liquid reservoir 813 corresponding to the two heaters 823 is greater than the capacity of the liquid reservoir 813 corresponding to the one heater 823, so that the number of heaters 823 can be adjusted according to the different conductivities of the atomized substrate. Of course, in other embodiments, both atomizer cores 82 can also be provided with a single heater 823. The power of the heater 823 in the atomizer core 82 corresponding to the larger liquid reservoir 813 can be adjusted to be greater than the power of the heater 823 in the atomizer core 82 corresponding to the smaller liquid reservoir 813. Alternatively, the size of the heater 823 in the atomizer core 82 corresponding to the larger liquid reservoir 813 can be adjusted to be greater than the size of the heater 823 in the atomizer core 82 corresponding to the smaller liquid reservoir 813, and the design requirements can also be met.

[0056] Here, the atomizer core 82 provided with two heating elements 823 is in fluid communication with the pneumatic switch 20 ′, and the atomizer core 82 provided with one heating element 823 is in fluid communication with the airflow sensor 20 .

[0057] In one embodiment, when the airflow sensor 20 is installed in the mounting hole 33 , in order to ensure sealing, the sensing component 100 provided in this embodiment further includes a connecting sleeve 40 , which is sleeved on the outside of the airflow sensor 20 and sealed in the mounting hole 33 .

[0058] In one embodiment, after the connecting sleeve 40 is sleeved onto the airflow sensor 20 , it is installed in the mounting hole 33 in a plugging manner and maintains an interference fit with the mounting hole 33 to achieve a sealing effect.

[0059] like Figures 1-4 As shown, a limiting portion 34 is further provided in the insertion slot 31, and the limiting portion 34 is used to limit the atomizer 80 installed in the insertion slot 31, so as to prevent the atomizer 80 from contacting the bottom of the insertion slot 31 and isolating the connecting hole 32 and the mounting hole 33 from the insertion slot 31, so as to keep the connecting hole 32 and the mounting hole 33 in a connected state with the insertion slot 31.

[0060] like Figure 4 As shown, the limiting portion 34 is a limiting block 341 provided at the bottom or side wall of the insertion slot 31. The height of the limiting block 341 away from the bottom of the insertion slot 31 is higher than the maximum height of the connecting hole 32 and the mounting hole 33 from the bottom of the insertion slot 31. Therefore, an avoidance space is formed between the atomizer 80 and the bottom of the insertion slot 31 by the limiting block 341, so that the connecting hole 32 and the mounting hole 33 remain in communication with the insertion slot 31.

[0061] In a specific embodiment, when the insertion portion 815 is inserted into the insertion slot 31, the limiting portion 34 limits the distance between the insertion portion 815 and the insertion slot 31, so that the height of the insertion portion 815 from the bottom of the insertion slot 31 is higher than the maximum height of the connecting hole 32 or the mounting hole 33 from the bottom of the insertion slot 31, thereby forming an avoidance space between the insertion portion 815 and the bottom of the insertion slot 31 through the limiting block 341.

[0062] After the insertion portion 815 is inserted into the insertion slot 31, in order to better combine the insertion portion 815 with the insertion slot 31, as shown in FIG. Figure 4 As shown, a notch 35 is provided on the side wall of the insertion slot 31. The setting of the notch 35 can enable the side wall of the insertion slot 31 to deform better, so that a tight fit can be achieved by deforming and squeezing the outer periphery of the insertion part 815 during the process of inserting the insertion part 815 into the insertion slot 31.

[0063] After the insertion portion 813 is inserted into the insertion slot 31 , in order to ensure a sealed connection between the bottom cover 812 and the sensor bracket 30 , in this embodiment, a sealing portion 36 is further provided in the circumference of the sensor bracket 30 , and the sealing portion 36 is used to be sealed and connected to the outer periphery of the atomizer 80 .

[0064] In a specific embodiment, the sealing portion 36 is an annular protruding structure provided on the periphery of the sensor bracket 30, such as Figure 8 As shown, an annular groove 8121 is provided on the side of the bottom cover 812 facing the sensor bracket 30. The ring-shaped protruding structure of the catch 36 is clamped in the annular groove 8121 to achieve a sealing effect.

[0065] When the control circuit board 10 controls the operation of the atomizer 80, it is difficult to intuitively display the operating status of the atomizer 80. Therefore, to facilitate user use, the atomizer device 200 provided in this embodiment also includes a display module 50. The display module 50 is fixedly connected to the control circuit board 10 and is located on the side of the control circuit board 10 facing away from the airflow sensor 20. The display module 50 can be used to display parameter information during the operation of the atomizer 80. The parameter information can include information about the start and stop of the atomizer 80 in the atomizer device 200, as well as information such as the number of puffs taken by the user. The display module 50 can also be used to display other information, such as animation effects, to enhance the user experience.

[0066] In some embodiments, the display module 50 is also arranged inside the shell 70, and the control circuit board 10 is located on the side where the airflow sensor 20 is set, which is the side facing the middle of the shell 70, and the limit module 50 is arranged on the side of the control circuit board 10 facing away from the airflow sensor 20, and the corresponding part of the shell 70 is set to be transparent or translucent to observe the information displayed by the display module 50.

[0067] In one embodiment, the display module 50 is mounted on a side of the control circuit board 10 facing away from the airflow sensor 20 via a mounting bracket 51 , so that the display module 50 and the control circuit board 10 can also form an integrated structure.

[0068] The atomizer 80 is heated by electric energy. Therefore, the atomizer 200 provided in this embodiment further includes a power supply circuit board 60 and a power supply unit 90. The power supply circuit board 60 is provided with a charging interface 61. The power supply circuit board 60 is fixedly connected to the control circuit board 10. The power supply circuit board 60 is connected to the power supply unit 90 (such as Figure 12 and Figure 13 As shown) is electrically connected to provide the electrical energy required for heating to the heating element 823 of the atomizing core 82 in the atomizer 80 through the power supply unit 90.

[0069] like Figures 6-10 As shown, the atomizing device 200 further includes a power supply bracket 91, on which the power supply unit 90 is mounted. The power supply bracket 91 is disposed below the sensor bracket 30 and is located between the power supply bracket 91 and the sensor bracket 30. The power supply bracket 91 has an arc-shaped mounting surface 911 for mounting and supporting the cylindrical power supply unit 90.

[0070] like Figure 5 As shown, the sensor bracket 30 is provided with a mounting groove 37 on the side facing away from the insertion groove 31, and the connecting hole 32 passes through the mounting groove 37. Figure 9 and Figure 10 As shown, an air intake channel 912 is provided inside the power supply bracket 91, and the air intake channel 912 is connected to the second air intake hole 72 provided on the outer shell 70, and the second air intake hole 72 is connected to the external atmosphere. The power supply bracket 91 is installed in the installation groove 31 with one end facing the sensor bracket 30, so that the connecting hole 32 is indirectly connected to the external atmosphere through the air intake channel 912.

[0071] In one embodiment, the power supply circuit board 90 and the control circuit board 10 are perpendicular to each other. Since the control circuit board 10 is larger than the power supply circuit board 90, the control circuit board 10 is installed in the height direction of the atomizing device 200, so that the display module 50 can face the side of the atomizing device 200, making it easier for the user to view the information displayed on the display module 50. The power supply circuit board 90 is installed in the width direction of the atomizing device 200, so that the charging port 61 faces the bottom of the atomizing device 200, ensuring the aesthetic appearance of the product surface and saving installation space for the control circuit board 10 and the power supply circuit board 90. In addition, an avoidance space is formed between the control circuit board 10 and the power supply circuit board 90, which can be used to install the atomizer 80 above the sensor bracket 30. The power supply bracket 91 is installed between the sensor bracket 30 and the power supply circuit board 60, thereby improving the utilization of the internal product layout space of the atomizing device 200.

[0072] Furthermore, the present application combines the display module 50 , the power supply circuit board 60 , the charging interface 61 on the power supply circuit board 60 and the control circuit board 10 into an integrated structure, which helps to improve product assembly efficiency during the product assembly stage.

[0073] See also Figure 11-13 As shown, the atomization device 200 provided in the present application also includes a housing 70, and the sensing component 100, the atomizer 80, the power supply unit 90 and the power supply bracket 91 are all arranged inside the housing 70, and the power supply unit 90 is installed on the power supply bracket 91. Among them, one end of the atomization channel 814 passes through the warehouse body 811 of the liquid storage mechanism 81. In some embodiments, in order to facilitate the user to inhale, the suction nozzle 71 is set on the housing 70, and the suction nozzle 71 is provided with a suction nozzle channel 711. The suction nozzle channel 711 is connected to one end of the atomization channel 814 that passes through the warehouse body 811. The user inhales through the suction nozzle 71, and the external atmosphere flows in the direction of the connecting hole 32, the insertion slot 31, the first air inlet 816, and the atomization channel 814 in sequence. When the atomization core 82 heats the atomization matrix to generate aerosol, the aerosol is output in the direction of the atomization channel 814 and the suction nozzle channel 711.

[0074] In one embodiment, two liquid storage members 813 are provided inside the liquid storage chamber 810. The two liquid storage members 813 are relatively independent and can store the same type or different types of atomized matrices. Each liquid storage member 813 is provided with an atomization channel 814, and the atomization channels 814 in the two liquid storage members 813 are connected to the nozzle channel 711 of the suction nozzle 71. At the same time, an atomization core 82 is provided in each of the two atomization channels 814. The two atomization cores 82 can work simultaneously or at different times, depending on actual needs.

[0075] like Figure 13As shown, the housing 70 includes a first shell 73 and a second shell 74. The first shell 73 and the second shell 74 are connected to each other to enclose an installation space for installing other components. A transparent shell 75 is also provided on the second shell 74. The transparent shell 75 is opposite to the display module 50 so that the information displayed by the display module 50 can be observed through the transparent shell 75.

[0076] like Figure 8 As shown, a control switch 11 is further provided on the control circuit board 10, and a button 76 is also installed on the second shell 74. The control switch 11 is used to connect the heating element 823 in the atomizer core 80 with the power supply unit 90. By pressing the control switch 11, the heating element 823 can be connected to the power supply unit 90.

[0077] In the atomizing device 200 provided in this embodiment, Figure 12 and Figure 13 As shown, an adjustment switch 77 is further provided at the second air inlet hole 72 , and the size of the second air inlet hole 72 can be adjusted by adjusting the switch 77 to adjust the amount of air intake through the second air inlet hole 72 .

[0078] In summary, in the atomizing device provided by the present application, the airflow sensor is installed on one side of the control circuit board, thereby forming an integrated structure with the control circuit board. Compared with the method of connecting with a wire harness by welding in the related art, the cost of using materials can be reduced, thereby reducing the production cost of this product. At the same time, after the airflow sensor and the control circuit board are fixed in an integrated structure, the layout space of the airflow sensor can also be reduced, and the internal space utilization rate of the product can be improved. Furthermore, the operator can assemble the airflow sensor only by installing the control circuit board, thereby reducing the assembly steps and improving the assembly efficiency of the product. The setting of the sensor bracket can achieve air path communication while installing the atomizer and the airflow sensor, saving air path layout space, and thus making the product layout more compact.

[0079] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
