DETAILED DESCRIPTION

[0033] The present application is further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application, but are not intended to limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application rather than all embodiments, and all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0034] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0035] See also Figures 1 to 4 , Figure 1 is a schematic diagram of the structure of the atomization device 10 provided in an embodiment of the present application, Figure 2 yes Figure 1 The exploded structural diagram of the atomization device 10 is shown in FIG. Figure 3 yes Figure 2 A schematic structural diagram of the middle housing assembly 100, Figure 4 yes Figure 3 Schematic diagram of the exploded structure of the middle housing assembly 100.

[0036] The atomizing device 10 provided in the embodiment of the present application can accommodate the substrate to be atomized, and can heat the substrate to be atomized so that the substrate to be atomized can be atomized to form an aerosol. For example, the atomizing device 10 can be an electronic cigarette, and the substrate to be atomized can be a smoke oil containing an extract of a tobacco plant. Alternatively, the substrate to be atomized can also be a liquid to be atomized containing extracts of other herbal plants with medical value, and the atomizing device 10 can be a handheld medical device for atomizing the aforementioned liquid to be atomized. Of course, the types of the atomizing device 10 and the substrate to be atomized can also be not limited to this, and this embodiment will not be repeated here.

[0037] like Figure 1 to Figure 2As shown, the atomization device 10 may include: a housing assembly 100, a pressure sensing assembly 200, a control assembly 300, and an atomization assembly 400. Among them, the housing assembly 100 can be used to install and protect various functional devices required for the atomization device 10, and can be grasped by the user for suction to derive the aerosol formed by the atomization of the substrate to be atomized in the housing assembly 100. The pressure sensing assembly 200 is arranged on the outer surface of the housing assembly 100, and can generate a corresponding electrical signal when the user touches the housing assembly 100. The control assembly 300 is arranged in the housing assembly 100 and is electrically connected to the pressure sensing assembly 200, and the control assembly 300 can receive and process the electrical signal generated by the pressure sensing assembly 200, and output a driving signal to control the atomization assembly 400 to atomize the substrate to be atomized. The atomization assembly 400 is arranged in the housing assembly 100 and is electrically connected to the control assembly 300, and the atomization assembly 400 can heat the substrate to be atomized contained under the control of the control assembly 300, so that the substrate to be atomized is atomized to form an aerosol. In this embodiment, the control component 300 can use the pressure sensing component 200 to accurately detect the user's action of using the atomizing device 10, so as to start the atomizing device 10 when it is confirmed that the user has a puffing action, thereby reducing the probability of the atomizing device 10 self-starting or failing.

[0038] The housing assembly 100 can be used to install and protect various functional components required by the atomizing device 10, and can be grasped and inhaled by the user to guide out the aerosol formed by the atomization of the atomizing matrix in the atomizing assembly 400. Figure 3 to Figure 4 As shown, the housing assembly 100 may include: a mounting shell 110 and a suction nozzle 120. Among them, the mounting shell 110 can be grasped by the user and has a accommodating space 101, and the accommodating space 101 can be installed with the control component 300 and the atomization component 400, and other various functional components required by the atomization device 10. The suction nozzle 120 is arranged on the mounting shell 110, and is connected to the atomization component 400 and the outside of the mounting shell 110, and the suction nozzle 120 can also be used by the user to suck in the mouth to derive the aerosol formed by the atomization of the atomization matrix in the atomization component 400. In addition, the outer surfaces of the mounting shell 110 and the suction nozzle 120 are respectively provided with corresponding structures in the pressure sensing component 200, so that when the user grasps the mounting shell 110 and the mouth-containing suction nozzle 120 (suction action), the pressure sensing component 200 can be touched by the user to generate an electrical signal to be transmitted to the control component 300 to start the atomization device 10.

[0039] Further, in order to facilitate the user to grasp the mounting shell 110, the mounting shell 110 can be set in a rectangular shape, and the outer surface of the mounting shell 110 can include: a top surface 111 and a bottom surface 112 arranged opposite to each other, and a side surface 113 respectively connecting the top surface 111 and the bottom surface 112. Among them, the top surface 111 and the bottom surface 112 can be two surfaces perpendicular to the length direction L of the mounting shell 110, and the side surface 113 can be a surface parallel to the length direction L. At the same time, a suction nozzle 120 can be provided on the top surface 111, and a corresponding structure in the pressure sensing component 200 can be provided on the side surface 113. When the user uses the atomizing device 10, the user's palm and fingers can be placed on the side surface 113 to grasp the mounting shell 110, and the top surface 111 of the mounting shell 110 can be placed in front of the mouth of the user, and the suction nozzle 120 located on the top surface 111 can be held in the mouth for suction. With such a configuration, the user can not only touch the partial structure of the pressure sensing component 200 located on the side 113, but also touch the partial structure of the pressure sensing component 200 located on the outer surface of the nozzle 120, so that the pressure sensing component 200 can generate a corresponding electrical signal to enable the atomization device 10 to accurately detect the user's suction action.

[0040] In some embodiments, the mounting shell 110 may also be provided with a vent hole on the bottom surface 112 that is connected to the atomizer assembly 400. When the user holds the mouthpiece 120 in the mouth for suction, air may enter the atomizer assembly 400 from the vent hole, and enter the mouthpiece 120 from the atomizer assembly 400, and then be guided from the mouthpiece 120 to the outside of the mounting shell 110 to form an airflow to bring out the aerosol formed by the atomization of the atomized matrix in the atomizer assembly 400. Of course, in addition to the vent hole, functional parts such as a charging interface may also be provided on the bottom surface 112, which is not limited in this embodiment.

[0041] Further, the side surface 113 may include: a first side surface 1131 and a second side surface 1132 disposed opposite to each other, and a third side surface 1133 and a fourth side surface 1134 connected to the first side surface 1131 and the second side surface 1132, and disposed opposite to each other. At the same time, the first side surface 1131 and the second side surface 1132 have the same area, the third side surface 1133 and the fourth side surface 1134 have the same area, and the area of ​​the first side surface 1131 is greater than the area of ​​the third side surface 1133. Among them, at least one of the first side surface 1131, the second side surface 1132, the third side surface 1133 and the fourth side surface 1134 is provided with a structure corresponding to the pressure sensing component 200. For example, considering that the first side surface 1131 and the second side surface 1132 have larger areas, they are more easily touched when the user grasps the mounting shell 110, so at least one of the first side surface 1131 and the second side surface 1132 may be provided with a structure corresponding to the pressure sensing component 200 to ensure that the pressure sensing component 200 can be touched when the user grasps the mounting shell 110. Of course, considering different design requirements, at least one of the first side surface 1131 and the third side surface 1133, or at least one of the third side surface 1133 and the fourth side surface 1134 may be provided with a structure corresponding to the pressure sensing component 200, and this embodiment is not limited to this. The following is only an example of the structure corresponding to the pressure sensing component 200 being provided on the first side surface 1131.

[0042] In some embodiments, considering that the position where the user grips the mounting shell 110 is not fixed and it is easy to fail to touch the pressure sensing component 200, a mark (pattern or depression) corresponding to the palm or finger of the user may be provided on the side 113 of the mounting shell 110, and the pressure sensing component 200 provided on the side 113 can at least cover the mark area of ​​the mounting shell 110. In this way, the mark on the side 113 can be used to guide the user's grip, so as to guide the user to touch the mark area of ​​the mounting shell 110 when gripping the mounting shell 110, thereby ensuring that the pressure sensing component 200 covering the mark area can be touched.

[0043] In some embodiments, considering the assembly problem of the atomizing device 10, the mounting shell 110 can be disassembled into a top cover 114 and a bottom shell 115. Figure 3 to Figure 4As shown, the bottom shell 115 can be a rectangular open structure, and the top cover 114 can be covered on the bottom shell 115, and can be enclosed together with the bottom shell 115 to form the aforementioned accommodating space 101. Among them, the side of the bottom shell 115 facing away from the top cover 114 can be the aforementioned first side 1131, and the side of the top cover 114 facing away from the bottom shell 115 can be the aforementioned second side 1132. At the same time, the two sides of the bottom shell 115 parallel to the length direction L and arranged opposite to each other can be the aforementioned third side 1133 and fourth side 1134, respectively, and the two sides of the bottom shell 115 perpendicular to the length direction L and arranged opposite to each other can be the aforementioned top surface 111 and bottom surface 112, respectively. In this embodiment, the top cover 114 and the bottom shell 115 can be assembled in a detachable or non-detachable manner such as bonding, screw connection or clamping.

[0044] It can be understood that the specific shape and structure of the aforementioned mounting shell 110 are only exemplary. In some embodiments, the shape and structure of the mounting shell 110 may not be limited thereto. It is only necessary that the mounting shell 110 can be grasped by the user and the outer surface of the mounting shell 110 touched by the user can be provided with a structure corresponding to the pressure sensing component 200. This embodiment does not limit this.

[0045] See also Figure 5 to Figure 6 , Figure 5 yes Figure 2 A schematic diagram of a partial cross-sectional structure of the middle housing assembly 100 along V-V, Figure 6 yes Figure 4 A schematic structural diagram of the middle suction nozzle 120.

[0046] The suction nozzle 120 is disposed on the mounting shell 110 and communicates with the inside and outside of the mounting shell 110. The suction nozzle 120 can be held in the mouth of a user for suction to guide out the aerosol formed by the atomization of the atomized matrix in the mounting shell 110. Figure 5 to Figure 6 As shown, the nozzle 120 can be inserted into the mounting shell 110, and one end of the nozzle 120 can be located inside the mounting shell 110, while the other opposite end can be located outside the mounting shell 110, so that the user can hold the nozzle in his mouth for suction. At the same time, the nozzle 120 also has a nozzle airway 121 that connects the inside and outside of the mounting shell 110, and the nozzle airway 121 can pass through the opposite ends of the nozzle 120 located inside and outside the mounting shell 110, and can be connected to the atomization component 400 in the mounting shell 110. In addition, a structure corresponding to the pressure sensing component 200 can be provided on the outer surface of the nozzle 120 away from the nozzle airway 121, so that the user can touch the structure corresponding to the pressure sensing component 200 when holding the nozzle 120 in his mouth.

[0047] Further, the suction nozzle 120 can be inserted into the mounting shell 110 from the top surface 111, and the suction nozzle 120 may include: a connecting portion 122 and a protruding portion 123. Among them, the connecting portion 122 is located in the mounting shell 110, and the connecting portion 122 can be connected to the atomizing assembly 400 to ensure the stability of the connection between the suction nozzle airway 121 and the atomizing assembly 400. The protruding portion 123 is connected to the connecting portion 122, and is arranged to protrude from the top surface 111 outside the mounting shell 110, and the protruding portion 123 can also be held in the mouth by the user. At the same time, the suction nozzle airway 121 can pass through one side of the connecting portion 122 away from the protruding portion 123, and the other opposite side of the protruding portion 123 away from the connecting portion 122, so as to connect the atomizing assembly 400 and the outside of the mounting shell 110. For example, the atomizer assembly 400 can be inserted into the nozzle airway 121 from the side of the connection portion 122 away from the protrusion 123, and can be threadedly connected with the surface of the connection portion 122 located in the nozzle airway 121 to achieve communication between the atomizer assembly 400 and the nozzle airway 121. In addition, the protrusion 123 also has an annular convex edge 1231 on the outer surface away from the nozzle airway 121, and the annular convex edge 1231 is located on the top surface 111 and can be snapped with the mounting shell 110 to prevent the protrusion 123 from falling into the mounting shell 110 under the action of external force. In this embodiment, the outer surfaces of the connection portion 122 and the protrusion 123 away from the nozzle airway 121 are provided with a structure corresponding to the pressure sensing assembly 200.

[0048] See also Figures 7 to 9 , Figure 7 yes Figure 2 A schematic diagram of the connection structure between the housing component 100 and the pressure sensing component 200, Figure 8 yes Figure 7 A schematic diagram of a partial cross-sectional structure of the mounting shell 110 and the first pressure sensing member 210 along V-V, Fig. 9 yes Figure 7 Schematic diagram of the partial cross-sectional structure of the middle suction nozzle 120 and the second pressure-sensitive member 220 along the V-V line.

[0049] The pressure sensing component 200 is disposed on the outer surface of the mounting shell 110 and the suction nozzle 120, and can generate an electrical signal when the user grasps the mounting shell 110 and holds the suction nozzle 120 in his mouth. Figures 7 to 9As shown, the pressure sensing component 200 may include: a first pressure sensing member 210 and a second pressure sensing member 220. The first pressure sensing member 210 is disposed on the outer surface of the mounting shell 110, and the second pressure sensing member 220 is disposed on the outer surface of the suction nozzle 120, and the first pressure sensing member 210 and the second pressure sensing member 220 are also electrically connected to the control component 300. When the user grasps the mounting shell 110 and the oral suction nozzle 120, the first pressure sensing member 210 and the second pressure sensing member 220 can be touched respectively to generate two electrical signals transmitted to the control component 300, and the control component 300 can output a driving signal based on the electrical signals generated by the first pressure sensing member 210 and the second pressure sensing member 220 to control the atomization component 400 to heat the atomization substrate so that the atomization substrate is atomized to form an aerosol. Through the above-mentioned arrangement, the first pressure-sensing member 210 and the second pressure-sensing member 220 can be used to accurately detect the user's action of using the atomizing device 10, so as to start the atomizing device 10 when it is confirmed that the user is gripping the mounting shell 110 and taking a suction action by holding the mouthpiece 120, thereby reducing the probability of the atomizing device 10 self-starting or failing.

[0050] Furthermore, the first pressure sensing element 210 may include: a first insulating layer 211, a first conductive layer 212, a first sensing layer 213 and a protective layer 214 which are sequentially stacked on the outer surface of the mounting shell 110. Figure 8 As shown, the first insulating layer 211 can be provided on the first side surface 1131 of the mounting shell 110, and the first insulating layer 211 can be used to maintain the electrical isolation between the first conductive layer 212 and the mounting shell 110. The first conductive layer 212 is located on the side of the first insulating layer 211 away from the first side surface 1131, and the first conductive layer 212 can be used to be electrically connected to the control component 300. The first sensing layer 213 is located on the side of the first conductive layer 212 away from the first insulating layer 211, and is electrically connected to the first conductive layer 212, and the first sensing layer 213 can change its resistance when the protective layer 214 is touched, and transmit it to the control component 300 to form an electrical signal. The protective layer 214 is located on the side of the first sensing layer 213 away from the first conductive layer 212, and the protective layer 214 can be used to protect the first sensing layer 213, the first conductive layer 212 and the first insulating layer 211.

[0051] Further, the protective layer 214 may be a PC (Polycarbonate, plastic) sheet, and the first sensing layer 213, the first conductive layer 212 and the first insulating layer 211 may be printed sequentially on a side of the protective layer 214 close to the first side surface 1131, and the material of the first sensing layer 213 may be a sensing carbon paste, the material of the first conductive layer 212 may be a conductive silver paste, and the material of the first insulating layer 211 may be an insulating ink. Of course, the materials of the first sensing layer 213, the first conductive layer 212 and the first insulating layer 211 may not be limited thereto, and the first sensing layer 213, the first conductive layer 212 and the first insulating layer 211 may not be limited to being formed on the protective layer 214 by printing, as long as the materials and formation methods of the first sensing layer 213, the first conductive layer 212 and the first insulating layer 211 can meet the required properties, and this embodiment does not limit this.

[0052] In some embodiments, considering that the protective layer 214 is thicker when it is a PC sheet, in order to prevent the first pressure sensing member 210 from forming a protrusion on the first side surface 1131, the mounting shell 110 may further be provided with a mounting groove 102 ( Figure 3 As shown), the shape and size of the mounting groove 102 can match the first pressure sensing member 210, so that the first pressure sensing member 210 can be accommodated by the mounting groove 102, thereby preventing the first pressure sensing member 210 from forming a protrusion on the first side surface 1131.

[0053] Furthermore, the first pressure-sensing member 210 may further include: an adhesive layer 215 located between the first insulating layer 211 and the mounting shell 110 (such as the first side surface 1131), so as to use the adhesive layer 215 to bond the first insulating layer 211 to the mounting shell 110, thereby ensuring the firmness of the first pressure-sensing member 210 on the mounting shell 110. Of course, in some embodiments, the design of the adhesive layer 215 may also be omitted, and the first insulating layer 211, the first conductive layer 212, and the first sensing layer 213 may also be printed on the first side surface 1131 of the mounting shell 110 in sequence, instead of being fixed to the mounting shell 110 by bonding.

[0054] Furthermore, the second pressure-sensing element 220 may include: a second sensing layer 221, a second insulating layer 222 and a second conductive layer 223. Fig. 9As shown, the second sensing layer 221 is arranged on the outer surface of the nozzle 120 away from the nozzle airway 121, and the second insulating layer 222 is located on the side of the second sensing layer 221 away from the nozzle 120, and is located outside the mounting shell 110. The second conductive layer 223 is located on the side of the second sensing layer 221 away from the nozzle 120, and is located inside the mounting shell 110. Among them, the second sensing layer 221 can change in resistance when the second insulating layer 222 is touched, and transmit it to the control component 300 to form an electrical signal, and the second insulating layer 222 can be used to keep the second sensing layer 221 electrically isolated from the outside. The second conductive layer 223 can be electrically connected to the second sensing layer 221 and the control component 300 respectively, so as to transmit the resistance change of the second sensing layer 221 to the control component 300.

[0055] Further, the second sensing layer 221 may be provided on the outer surface of the connecting portion 122 and the protruding portion 123 away from the nozzle air passage 121, and the second insulating layer 222 is located on the side of the second sensing layer 221 away from the protruding portion 123, and the second conductive layer 223 is located on the side of the second sensing layer 221 away from the connecting portion 122. That is, the second sensing layer 221 may be divided into a first region 2211 covering the outer surface of the protruding portion 123 away from the nozzle air passage 121, and a second region 2212 covering the outer surface of the connecting portion 122 away from the nozzle air passage 121, and the second insulating layer 222 may cover the first region 2211, and the second conductive layer 223 may cover the second region 2212.

[0056] Further, the second sensing layer 221 can be printed on the outer surface of the connecting portion 122 and the protruding portion 123 away from the nozzle airway 121, and the material of the second sensing layer 221 can be sensing carbon paste. Similarly, the second insulating layer 222 and the second conductive layer 223 can also be printed on the second sensing layer 221, and the material of the second insulating layer 222 can be insulating ink, and the material of the second conductive layer 223 can be conductive silver paste. Of course, the materials of the second sensing layer 221, the second insulating layer 222 and the second conductive layer 223 may not be limited thereto, and the second sensing layer 221, the second insulating layer 222 and the second conductive layer 223 may not be limited to being formed on the protective layer 214 by printing. It only needs that the materials and formation methods of the second sensing layer 221, the second insulating layer 222 and the second conductive layer 223 can meet the required properties, and this embodiment does not limit this.

[0057] When the user grips the mounting shell 110 and touches the protective layer 214, the first sensing layer 213 may change in resistance and be transmitted to the control component 300 through the first conductive layer 212 to form an electrical signal, so that the atomizing device 10 can detect the user's gripping action. When the user touches the second insulating layer 222 with the mouthpiece 120, the second sensing layer 221 may change in resistance and be transmitted to the control component 300 through the second conductive layer 223 to form an electrical signal, so that the atomizing device 10 can detect the user's mouth-holding action. With such a configuration, the first pressure-sensing member 210 and the second pressure-sensing member 220 can be used to accurately detect the user's suction action using the atomizing device 10, so as to start the atomizing device 10 when it is confirmed that the user has gripped the mounting shell 110 and the mouthpiece 120 to suck, thereby reducing the probability of the atomizing device 10 self-starting or failing. At the same time, the atomization device 10 of this embodiment is also simpler to use. The atomization device 10 can be started without complicated operations (such as multiple touches or continuous swiping), which greatly improves the convenience of users using the atomization device 10.

[0058] Please refer to 10 to Fig.12 , Fig.10 yes Figure 1 A schematic diagram of a partial cross-sectional structure of the atomization device 10 along V-V, Fig.11 yes Fig.10 A partial enlarged schematic diagram of point A in the middle. Fig.12 yes Fig.10 A local enlarged schematic diagram of point B in the middle.

[0059] The control assembly 300 is disposed in the mounting housing 110 and is electrically connected to the first pressure sensing element 210, the second pressure sensing element 220 and the atomizing assembly 400. Fig.10 As shown, the control component 300 may include: a circuit board 310 and a control module 320. The circuit board 310 is disposed in the accommodating space 101, and the circuit board 310 is also electrically connected to the first pressure-sensitive member 210, the second pressure-sensitive member 220 and the atomizing component 400. The control module 320 is electrically connected to the circuit board 310, and is configured to receive and process the electrical signals transmitted by the first pressure-sensitive member 210 and the second pressure-sensitive member 220 through the circuit board 310, and output a driving signal to control the atomizing component 400 to heat the substrate to be atomized, so that the substrate to be atomized is atomized to form an aerosol.

[0060] Furthermore, the atomizing device 10 may further include: a first electrical connection assembly 500 electrically connected to the circuit board 310 and the first pressure sensing element 210 respectively. Fig.11As shown, the first electrical connection assembly 500 may include: a first elastic conductive member 510 and a flexible electrical connection member 520. Since the first pressure sensing member 210 is provided on the first side 1131, the circuit board 310 may be arranged opposite to the first side 1131, and the first elastic conductive member 510 may be arranged on the circuit board 310, and electrically connected to the circuit board 310, and located on the side of the circuit board 310 facing the first side 1131. One end of the flexible electrical connection member 520 is connected to the first elastic conductive member 510, and the other end is passed through the mounting shell 110 and electrically connected to the first pressure sensing member 210. For example, the mounting shell 110 is provided with a notch 103 on the first side surface 1131 that is connected to the accommodating space 101, and a portion of the first conductive layer 212 corresponding to the notch 103 is not blocked by the first insulating layer 211, that is, a portion of the first conductive layer 212 corresponding to the notch 103 is exposed outside the first insulating layer 211, and the other end of the flexible electrical connector 520 can pass through the mounting shell 110 from the notch 103 and be electrically connected (such as welded) to the first conductive layer 212. In this embodiment, the first elastic conductive member 510 can be an elastic conductive structure such as a spring electrode, a conductive probe or a conductive spring, and the flexible electrical connector 520 can be a flexible conductive structure such as a flexible circuit board or an electrical connection line.

[0061] Furthermore, the atomizing device 10 may further include: a second electrical connection assembly 600 electrically connected to the circuit board 310 and the second pressure sensing element 220 respectively. Fig.12 As shown, the second electrical connection component 600 may include: a second elastic conductive member 610 and a rigid electrical connection member 620. Among them, the second elastic conductive member 610 may be arranged on the circuit board 310, and electrically connected to the circuit board 310, and is located on the side of the circuit board 310 away from the first side 1131. The rigid electrical connection member 620 is arranged in the mounting shell 110, and is electrically in contact with the second elastic conductive member 610 and the second pressure-sensitive member 220, respectively. For example, the rigid electrical connection member 620 may be embedded in the inner wall of the mounting shell 110 away from the first side 1131, and may be electrically in contact with the outer surface (second conductive layer 223) of the connecting portion 122 away from the nozzle airway 121, and the second elastic conductive member 610 may be bent toward the top surface 111, and elastically abut (electrically contact) with the rigid electrical connection member 620. In this embodiment, the second elastic conductive member 610 may also be an elastic conductive structure such as a spring electrode, a conductive probe or a conductive spring, and the rigid electrical connector 620 may be a rigid conductive structure such as a conductive steel plate.

[0062] Through the above arrangement, the rigid electrical connector 620 can be used to reduce the difficulty of achieving electrical connection between the second elastic conductive member 610 and the second pressure-sensitive member 220. That is, since the outer surface of the connecting portion 122 facing away from the nozzle airway 121 is generally an arc surface, it is difficult to connect the second conductive layer 223 using the flexible electrical connector 520. Based on this, the present embodiment can reduce the difficulty of achieving electrical connection between the second elastic conductive member 610 and the second pressure-sensitive member 220 by embedding the rigid electrical connector 620 in the mounting shell 110 and electrically contacting the second elastic conductive member 610 and the second pressure-sensitive member 220 through the rigid electrical connector 620.

[0063] It is understandable that the specific structures of the aforementioned first electrical connection component 500 and the second electrical connection component 600 are only exemplary. In some embodiments, the first electrical connection component 500 and the second electrical connection component 600 may not be limited to the solutions of the above embodiments. The specific electrical connection structures adopted by the two can be adaptively adjusted according to the design requirements of the atomization device 10. It is only necessary for the first electrical connection component 500 and the second electrical connection component 600 to be able to play the role of electrical connection. This embodiment will not be illustrated one by one here.

[0064] See also Figure 13 to Figure 14 , Fig.13 yes Fig.10 The structural diagram of the control module 320 is shown in FIG. Fig.14 yes Fig.13 Schematic diagram of the circuit structure of the control module 320.

[0065] The control module 320 is electrically connected to the circuit board 310, and is capable of receiving and processing the electrical signals transmitted by the first pressure sensing element 210 and the second pressure sensing element 220, and outputting a driving signal to control the atomizing assembly 400 to work. Figure 13 to Figure 14 As shown, the control module 320 may include: an output control unit 321, a signal processing unit 322 and a power supply unit 323. The signal processing unit 322 may be electrically connected to the first pressure-sensitive member 210 and the second pressure-sensitive member 220, respectively, and the signal processing unit 322 may convert the resistance change of the first pressure-sensitive member 210 and the second pressure-sensitive member 220 into an electrical signal, and transmit it to the output control unit 321. The output control unit 321 may be electrically connected to the atomization assembly 400, and the output control unit 321 may output a driving signal based on the electrical signal transmitted by the signal processing unit 322 to control the atomization assembly 400 to work. The power supply unit 323 may be electrically connected to the output control unit 321, and the power supply unit 323 may also be electrically connected to the battery 700 of the atomization device 10 to power the output control unit 321 and the signal processing unit 322.

[0066] Further, the output control unit 321 may include: a central control unit 3211, an output power control unit 3212, and an impedance detection unit 3213. Among them, the central control unit 3211 can be connected to the signal processing unit 322 and the power supply unit 323, and can receive and process the electrical signal transmitted by the signal processing unit 322 to output a driving signal to the output power control unit 3212. The output power control unit 3212 can be connected to the central control unit 3211 and the atomization assembly 400 respectively, and can control the atomization assembly 400 to heat the atomized substrate based on the driving signal output by the central control unit 3211. The impedance detection unit 3213 can be connected to the central control unit 3211 and the atomization assembly 400 respectively, and the impedance detection unit 3213 can detect the impedance value of the atomization assembly 400 for the central control unit 3211 to analyze and calculate, so as to output the correct driving signal.

[0067] Further, the signal processing unit 322 may include: two pressure sensors 3221, and the two pressure sensors may be electrically connected to the first pressure sensing member 210 and the second pressure sensing member 220, respectively, to convert the resistance change of the first pressure sensing member 210 and the second pressure sensing member 220 into electrical signals, and further transmit them to the output control unit 321. Of course, in some embodiments, the number of pressure sensors may also be one, so that the resistance change of the first pressure sensing member 210 and the second pressure sensing member 220 may be converted into electrical signals by using one pressure sensor, and further transmit them to the output control unit 321. It can be understood that Fig.14 The circuit structure diagram of the control module 320 shown is only one embodiment of the circuit structure that can be selected by the control module 320. In other embodiments, the circuit structure of the control module 320 can also be adaptively adjusted according to design requirements, and is not limited to Fig.14 The circuit structure shown is not limited in this embodiment.

[0068] See also Fig.15 , Fig.15 yes Figure 1 A schematic diagram of the partial cross-sectional structure of the atomization device 10 along VI-VI.

[0069] The atomizing assembly 400 is disposed in the mounting housing 110 and is electrically connected to the control assembly 300. The atomizing assembly 400 is capable of heating the contained substrate to be atomized so as to atomize the substrate to be atomized to form an aerosol. Fig.15As shown, the atomization assembly 400 may include: a liquid storage bottle 410, a liquid storage part 420, an air guide tube 430, a liquid guide part 440 and a heating element 450. Among them, the liquid storage bottle 410 is arranged in the accommodating space 101, and the bottle mouth of the liquid storage bottle 410 is also inserted in the nozzle airway 121 of the nozzle 120. The liquid storage part 420 is arranged in the liquid storage bottle 410, and the liquid storage part 420 can be used to accommodate the matrix to be atomized. The air guide tube 430 is embedded in the liquid storage part 420, and is respectively connected to the nozzle airway 121 and the aforementioned vent, and the air guide tube 430 is also provided with a hole connected to the liquid storage part 420. The liquid guide member 440 is disposed in the air guide tube 430 and blocks the hole of the air guide tube 430 communicating with the liquid storage member 420. The liquid guide member 440 can guide the substrate to be atomized contained in the liquid storage member 420 into the air guide tube 430. The heating member 450 is disposed on the air guide tube 430, and the liquid guide member 440 can be disposed around the heating member 450. The heating member 450 can heat the substrate to be atomized on the liquid guide member 440 under the control of the control component 300, so that the substrate to be atomized is atomized to form an aerosol.

[0070] It can be understood that the structure of the aforementioned atomizer assembly 400 is only an example. In other embodiments, the structure of the atomizer assembly 400 may not be limited thereto. It is only necessary that the atomizer assembly 400 can accommodate the substrate to be atomized and can heat the substrate to be atomized under the control of the control assembly 300 so that the substrate to be atomized can be atomized to form an aerosol. This embodiment does not limit this.

[0071] See also Fig.16 , Fig.16 It is a flow chart of the control method of the atomization device provided in the embodiment of the present application.

[0072] like Fig.16 As shown, the control method of the atomization device provided in the embodiment of the present application can be used to control the atomization device 10 in the above embodiment, and the control method of the atomization device can include the following steps:

[0073] S10, receiving a first touch signal.

[0074] S40, receiving a second touch signal.

[0075] S70, outputting a driving signal based on the first touch signal and the second touch signal.

[0076] Specifically, the first touch signal can be triggered by the first pressure-sensitive member 210, and the second touch signal can be triggered by the second pressure-sensitive member 220. For example, when the user grasps the mounting shell 110, the first pressure-sensitive member 210 can be touched by the user to generate a first touch signal. When the user holds the mouthpiece 120 in his mouth, the second pressure-sensitive member 220 can be touched by the user to generate a second touch signal. The control component 300 can receive the first touch signal and the second touch signal, and the control component 300 can analyze and calculate the first touch signal and the second touch signal, and send a drive signal based on the first touch signal and the second touch signal to drive the atomization component 400 to heat the contained matrix to be atomized, thereby realizing the start of the atomization device 10. The control method of the atomization device provided in this embodiment can detect the suction action of the user using the atomization device 10 using the two received touch signals, so as to start the atomization device 10 when confirming that the user has a suction action, thereby reducing the probability of the atomization device 10 self-starting due to an accidental touch. At the same time, since there is no complicated judgment logic (such as multiple touches or continuous swiping, etc.), the control method of the atomization device provided in this embodiment also has the advantage of simple overall control logic, which is conducive to improving the response speed of the atomization device 10.

[0077] In some embodiments, the first touch signal may also be triggered by the second pressure-sensitive member 220, and the second touch signal may also be triggered by the first pressure-sensitive member 210, and the control component 300 only needs to be able to receive and obtain the first touch signal and the second touch signal. At the same time, in some embodiments, step S10 and step S40 may not be limited to being executed in sequence, and step S10 and step S40 may also be executed simultaneously. In addition, in some embodiments, the execution order of step S10 and step S40 may also be interchangeable. That is, when receiving a touch signal, step S40 may be executed first, and then step S10 may be executed, and this embodiment does not limit this.

[0078] The atomizing device 10 provided in the present application is provided with a first pressure-sensitive member 210 and a second pressure-sensitive member 220 on the mounting shell 110 and the mouthpiece 120, respectively, and the first pressure-sensitive member 210 and the second pressure-sensitive member 220 are also electrically connected to the control assembly 300 located in the mounting shell 110, so that the control assembly 300 can receive the electrical signal triggered by the first pressure-sensitive member 210 and the second pressure-sensitive member 220 when the user grasps the mounting shell 110 and the mouthpiece 120, and output a driving signal to control the atomizing assembly 400 electrically connected to the control assembly 300 to atomize the atomized matrix. In this way, the first pressure-sensitive member 210 and the second pressure-sensitive member 220 can be used to accurately detect the user's action of using the atomizing device 10, so as to start the atomizing device 10 when confirming that the user has grasped the mounting shell 110 and the mouthpiece 120, thereby reducing the probability of the atomizing device 10 starting or failing.

[0079] The above are only implementation methods of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
