[0072] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0073] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0074] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0075] References to "one embodiment", "some embodiments" or "an embodiment" described in the specification of this application mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "in one embodiment", "in some other embodiments", "in some other embodiments", etc., which appear at different places in this specification, do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. In addition, in one or more embodiments, particular features, structures or characteristics may be combined in any suitable manner.

[0076] In order to illustrate the technical solution of the present application, a description is given below with reference to specific drawings and embodiments.

[0077] In the related art, the aerosol generating device generally also includes a power supply. After the production is completed, the atomizing component is often directly electrically connected to the power supply. This causes the aerosol generating device to easily self-start during subsequent transportation or under bumpy conditions. If the liquid aerosol generating matrix inside the aerosol generating device leaks, it may also cause the internal circuit of the aerosol generating device to short-circuit.

[0078] In view of this, the present application provides a circuit board on-off component and a method of using the same, and an aerosol generating device. Since the circuit board is arranged inside the shell, the circuit board includes a first circuit and a second circuit arranged at intervals, the first circuit is used to electrically conduct with the power supply, the second circuit is used to electrically conduct with the atomizing component, and the elastic member is used to apply an elastic force toward the circuit board to the moving member, and the moving member is connected to the shell to limit the moving member from moving in a direction close to the circuit board. Therefore, during transportation or under conditions such as bumps, the first circuit and the second circuit arranged at intervals can be used to avoid electrical conduction between the power supply and the atomizing component, thereby avoiding the problem of the atomizing component generating a self-starting phenomenon. Since the moving member can also be separated from the shell, the moving member can be driven by the elastic member to move in a direction close to the circuit board and push the conducting member, and the first circuit and the second circuit are electrically conducted through the conducting member, so that the power supply and the atomizing component can be electrically conducted through the conducting member during normal use, ensuring the normal use of the aerosol generating device.

[0079] Please refer to Figures 1 to 4 , Figure 1 is a schematic diagram of the structure of an aerosol generating device 100 in one embodiment of the present application. Figure 2 yes Figure 1 The aerosol generating device 100 is shown in a right side view. Figure 3 yes Figure 2 The cross-sectional view of the aerosol generating device 100 along the JJ direction is shown. Figure 4 yes Figure 3 A partial enlarged view of point A in the middle. Figure 5 yes Figure 3 A partial enlarged view of point B in the middle.

[0080] On the one hand, an embodiment of the present application provides an on-off electrical component of a circuit board 40, which is used for an aerosol generating device 100. The aerosol generating device 100 includes a power supply 10 and an atomization component 20. The on-off electrical component includes a shell 30, a circuit board 40, a conductive part 50, a moving part 60 and an elastic part 70.

[0081] The power source 10 may include a battery. The atomizing assembly 20 heats, ultrasonically vibrates or otherwise processes the aerosol-generating substrate to atomize it into tiny particles, which are suspended in the air to form an aerosol. The aerosol-generating substrate may include an atomizing liquid.

[0082] The circuit board 40 is disposed inside the shell 30 , and the circuit board 40 includes a first circuit (not shown in the figure) and a second circuit (not shown in the figure) arranged at intervals. The first circuit is used for electrically conducting with the power supply 10 , and the second circuit is used for electrically conducting with the atomization assembly 20 .

[0083] The first circuit and the second circuit can be copper wires, silver wires or aluminum wires etched on the circuit board 40. The first circuit and the second circuit can also be other structures. The first circuit and the second circuit are spaced apart and therefore are not conductive.

[0084] The conducting member 50 and the moving member 60 are both disposed inside the housing 30 and are sequentially arranged in a direction away from the circuit board 40 .

[0085] The conductive member 50 is conductive and can be a metal member, such as a copper sheet, an aluminum sheet, or an iron sheet. The conductive member 50 can also be a non-metal member, such as a graphite sheet. Figure 3 The direction indicated by the arrow t.

[0086] The elastic member 70 is used to apply an elastic force to the moving member 60 toward the circuit board 40 . The moving member 60 is connected to the housing 30 to limit the moving member 60 from moving toward the circuit board 40 .

[0087] The elastic force applied by the elastic member 70 to the moving member 60 toward the circuit board 40 may be a tensile force or a compressive force. Figure 3 The direction indicated by the arrow s.

[0088] For example, the elastic force applied by the elastic member 70 to the moving member 60 toward the circuit board 40 is a pulling force. The elastic member 70 is arranged on the side of the moving member 60 facing the circuit board 40. One end of the elastic member 70 is connected to the moving member 60, and the other end of the elastic member 70 is connected to the shell 30 or the circuit board 40.

[0089] For another example, as in the present embodiment, the elastic force applied by the elastic member 70 to the moving member 60 toward the circuit board 40 is pressure, and the elastic member 70 is arranged on the side of the moving member 60 facing away from the circuit board 40, one end of the elastic member 70 abuts against the moving member 60, and the other end of the elastic member 70 abuts against the shell 30.

[0090] The elastic member 70 may be a spring, elastic metal, elastic rubber, or the like.

[0091] Please refer to Fig.11 , Fig.12 , Fig.13 and Fig.14 , Fig.11 Yes Figure 1 The right side view of the aerosol generating device 100 after the moving part 60 and the housing 30 are separated is shown in FIG. Fig.12 yes Fig.11 The cross-sectional view of the aerosol generating device 100 along the LL direction is shown. Fig.13 yes Fig.12 A partial enlarged view of point E in the middle. Fig.14 yes Fig.12 A partial enlarged view of point F in the middle.

[0092] The moving member 60 can also be separated from the housing 30 , so that the moving member 60 can move toward the circuit board 40 and push the conductive member 50 under the drive of the elastic member 70 , and the conductive member 50 electrically connects the first circuit and the second circuit.

[0093] The conducting member 50 electrically conducts the first circuit and the second circuit, that is, the power source 10 and the atomizing assembly 20 are electrically conducted through the conducting member 50 .

[0094] It is understandable that the moving part 60 is detachably connected to the housing 30, such as by magnetic attraction, bonding, clamping, bolt connection, screw connection or snap connection. When the moving part 60 does not push the conductive part 50, the first circuit and the second circuit are not conductive. The conductive part 50 and / or the moving part 60 can be clearance-fitted or slidingly fitted with the housing 30 to enable the conductive part 50 and / or the moving part 60 to move in the housing 30 toward the direction close to the circuit board 40. The moving part 60 can be directly connected to the conductive part 50, the conductive part 50 is conductive, and the moving part 60 is insulating.

[0095] The method for using the on-off electrical component of the circuit board 40 provided in the embodiment of the present application includes: separating the moving part 60 from the shell 30, so that the moving part 60 can move toward the direction close to the circuit board 40 under the drive of the elastic part 70 and push the conductive part 50, and the conductive part 50 electrically connects the first circuit and the second circuit.

[0096] The on-off electrical component of the circuit board 40 provided in the embodiment of the present application is that the circuit board 40 is arranged inside the shell 30, and the circuit board 40 includes a first circuit and a second circuit arranged at intervals. The first circuit is used to electrically conduct with the power supply 10, and the second circuit is used to electrically conduct with the atomizer assembly 20, and the elastic member 70 is used to apply an elastic force toward the circuit board 40 to the moving member 60. The moving member 60 is connected to the shell 30 to limit the movement of the moving member 60 in the direction close to the circuit board 40. Therefore, during transportation or under bumpy conditions, the first circuit and the second circuit arranged at intervals can prevent the power supply 10 and the atomizer assembly 20 from being electrically conducted, thereby avoiding the problem of self-starting of the atomizer assembly 20.

[0097] Furthermore, since the moving part 60 can be separated from the shell 30, the moving part 60 can be driven by the elastic part 70 to move toward the direction close to the circuit board 40 and push the conductive part 50, and electrically connect the first circuit and the second circuit through the conductive part 50, so that the power supply 10 and the atomization assembly 20 can be electrically connected through the conductive part 50 during normal use, thereby ensuring the normal use of the aerosol generating device 100.

[0098] Please refer to Figure 6 , Figure 7 , Figure 8 , Fig.15 , Fig.16 , Fig.17 , Fig.21 and Fig. 22 , Figure 6 yes Figure 1 The front view of the aerosol generating device 100 is shown. Figure 7 yes Figure 6 The cross-sectional view of the aerosol generating device 100 along the KK direction is shown. Figure 8 yes Figure 7 A partial enlarged view of point C in the middle. Fig.15 yes Fig.11 The front view of the aerosol generating device 100 is shown. Fig.16 yes Fig.15 The cross-sectional view of the aerosol generating device 100 along the MM direction is shown. Fig.17 yes Fig.16 A partial enlarged view of the G in the middle. Fig.21 Yes Figure 1 The schematic diagram of the structure of the moving part 60 in the aerosol generating device 100 is shown in FIG. Fig. 22 Yes Fig.21 A schematic structural diagram of the moving part 60 from another perspective is shown.

[0099] In this embodiment, the housing 30 is provided with an opening 301 , and the moving member 60 includes a main body 61 and two elastic holding arms 62 , and the two elastic holding arms 62 are arranged at intervals.

[0100] The on-off power assembly also includes a removal piece 80, which is detachably connected to the shell 30. The removal piece 80 is provided with an insertion portion 801, which is inserted between two elastic clamping arms 62, so that the two elastic clamping arms 62 are respectively clamped on the opposite side walls of the opening 301 to achieve the connection between the moving piece 60 and the shell 30. The insertion portion 801 can also be moved out from between the two elastic clamping arms 62, so that the two elastic clamping arms 62 are respectively disengaged from the opposite side walls of the opening 301 to achieve the separation of the moving piece 60 from the shell 30.

[0101] By adopting the above method, the moving part 60 can be connected to the shell 30 by only inserting the insertion part 801 between the two elastic clamping arms 62. At the same time, the moving part 60 can be separated from the shell 30 by only moving the insertion part 801 out from between the two elastic clamping arms 62, thereby making the process of connecting the moving part 60 and the shell 30 and the process of separating the moving part 60 and the shell 30 more convenient.

[0102] For example, the removal member 80 and the housing 30 can be detachably connected by means of magnetic attraction, bonding, clamping, bolt connection, screw connection or snap connection.

[0103] It should be noted that the end of the elastic clamping arm 62 away from the main body 61 may be arranged to clamp and cooperate with the side wall of the opening 301 .

[0104] Optionally, two opposite side walls of the opening 301 are provided with protrusions 31 , and the protrusions 31 are used for engaging with the elastic engaging arms 62 .

[0105] Such arrangement facilitates the two elastic clamping arms 62 to be clamped on the two protrusions 31 on the two opposite side walls of the opening 301 .

[0106] It can be understood that the two elastic holding arms 62 are respectively disengaged from the two opposite side walls of the opening 301 , that is, the two elastic holding arms 62 are respectively disengaged from the two protrusions 31 on the two opposite side walls of the opening 301 .

[0107] It should be noted that, when installing the on-off power assembly of the circuit board 40 provided in the above embodiment, the movable part 60 can be moved in a direction away from the circuit board 40, the elastic part 70 is compressed by force, and the removal part 80 is connected to the shell 30, and the insertion part 801 is inserted between the two elastic clamping arms 62 of the movable part 60, so that the two elastic clamping arms 62 are respectively clamped on the two protrusions 31 on the opposite side walls of the opening 301.

[0108] The first guide slope 311 is provided on one side of the protrusion 31 close to the removal member 80. The first guide slope 311 is used to contact the elastic clamping arm 62. In the direction from the circuit board 40 to the removal member 80, the distance between the first guide slope 311 and the axis of the opening 301 gradually increases. The direction from the circuit board 40 to the removal member 80 can be Figure 8 and Fig.17 The direction indicated by the arrow t.

[0109] By adopting the above solution, after the insertion portion 801 is moved out from between the two elastic clamping arms 62 , the elastic clamping arms 62 can be moved along the first guide slope 311 , thereby facilitating the separation of the elastic clamping arms 62 from the protrusion 31 .

[0110] Optionally, the elastic clamping arm 62 is provided with a guiding slope 621 , and in the direction from the circuit board 40 to the removal member 80 , the distance between the guiding slope 621 and the axis of the opening 301 gradually increases, and the guiding slope 621 is used to slidably contact the first guiding slope 311 .

[0111] With such arrangement, after the insertion portion 801 is moved out from between the two elastic clamping arms 62 , the guide slope 621 of the elastic clamping arm 62 can be in sliding contact with the first guide slope 311 , thereby facilitating the separation of the elastic clamping arm 62 from the protrusion 31 .

[0112] Optionally, a second guide slope 312 is provided on the side of the protrusion 31 away from the removal member 80, and the second guide slope 312 is used to contact the elastic clamping arm 62. In the direction from the circuit board 40 to the removal member 80, the distance between the second guide slope 312 and the axis of the opening 301 gradually decreases.

[0113] With such arrangement, when installing the on-off power component of the circuit board 40, the elastic clamping arm 62 of the movable part 60 can contact the second guide slope 312 during the process of moving the movable part 60 in the direction away from the circuit board 40, so that the elastic clamping arm 62 can move to the side of the protrusion 31 close to the removal part 80 and engage with the protrusion 31.

[0114] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Fig. 9 and Fig.10 , Fig. 9 yes Figure 1 The exploded structural diagram of the aerosol generating device 100 shown in FIG. Fig.10 yes Fig. 9 A partial enlarged view of point D in the middle.

[0115] In this embodiment, the removal member 80 is bonded to the housing 30 .

[0116] By adopting the above solution, the removal member 80 can be detachably connected to the housing 30 .

[0117] Optionally, the removal piece 80 includes an adhesive layer 81 and a patch 82 that are stacked and connected, the adhesive layer 81 is bonded to the shell 30, the adhesive layer 81 is provided with a first avoidance hole 811, the insertion part 801 is provided on the patch 82, the insertion part 801 passes through the first avoidance hole 811 and is inserted between the two elastic clamping arms 62.

[0118] With such a configuration, it is only necessary to set the insertion portion 801 on the patch 82, and the adhesive layer 81 does not need to set the insertion portion 801. The patch 82 can be used to ensure that the insertion portion 801 has a certain strength, which is convenient for insertion between the two elastic clamping arms 62, and also convenient for bonding the removal piece 80 and the shell 30 together.

[0119] Optionally, the patch 82 is provided with a second avoidance hole 821 , and one end of the elastic holding arm 62 away from the main body 61 passes through the first avoidance hole 811 and is accommodated in the second avoidance hole 821 .

[0120] Such a configuration can prevent the end of the elastic clamping arm 62 away from the main body 61 from protruding out of the patch 82 , which would cause the elastic clamping arm 62 to be mistriggered and cause the elastic clamping arm 62 to be separated from the protrusion 31 .

[0121] In order to facilitate the separation of the removal piece 80 from the housing 30 , the adhesive layer 81 is provided with a peeling portion 812 , and the peeling portion 812 protrudes from the patch 82 .

[0122] With such a configuration, the adhesive layer 81 and the patch 82 can be separated from the housing 30 through the peeling portion 812 .

[0123] It is understandable that the peeling portion 812 may not be adhesive.

[0124] As another way to achieve a detachable connection between the shell 30 and the moving part 60, the shell 30 is provided with a first socket, the moving part 60 is provided with a second socket, and the power on / off assembly also includes a pin, which is inserted into the first socket and the second socket to achieve the connection between the moving part 60 and the shell 30, and the pin can also be removed from the first socket and the second socket to achieve the separation of the moving part 60 from the shell 30.

[0125] By adopting the above scheme, the moving part 60 can be connected to the shell 30 by only inserting the pin into the first socket and the second socket, and the moving part 60 can be separated from the shell 30 by only removing the pin from the first socket and the second socket, thereby making the process of connecting the moving part 60 and the shell 30 and the process of separating the moving part 60 and the shell 30 more convenient.

[0126] Please refer to Figure 3 , Figure 4 , Figure 7 , Figure 8 , Fig.21 and Fig. 22 In this embodiment, the shell 30 includes a first guide portion 32, and the moving member 60 includes a second guide portion 63. The second guide portion 63 is slidably matched with the first guide portion 32, and the sliding direction of the second guide portion 63 relative to the first guide portion 32 is parallel to the elastic force direction of the elastic member 70.

[0127] By adopting the above solution, the moving part 60 can be separated from the housing 30 so that when the moving part 60 moves toward the circuit board 40 driven by the elastic part 70, the moving part 60 moves more smoothly without obvious shaking.

[0128] For example, the first guide portion 32 may be a guide groove, and the second guide groove may be a guide block. Alternatively, the first guide portion 32 may be a guide block, and the second guide groove may be a guide groove.

[0129] Optionally, the first guide portion 32 is slidably mounted on the second guide portion 63 , and the elastic member 70 is located inside the second guide portion 63 .

[0130] Such an arrangement can make the first guide portion 32 slide more smoothly relative to the second guide portion 63 and can prevent the elastic member 70 from being significantly bent.

[0131] For example, the second guide portion 63 and the first guide portion 32 may both be annular in shape.

[0132] Optionally, the elastic member 70 abuts against the second guide portion 63 to apply an elastic force to the moving member 60 toward the circuit board 40 .

[0133] Such a configuration enables the elastic force of the elastic member 70 to directly act on the second guide portion 63 , thereby making the second guide portion 63 slide more smoothly relative to the first guide portion 32 .

[0134] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Fig.18 and Fig.19 In this embodiment, the conductive member 50 includes a spring, one of the first circuit and the second circuit is connected to one end of the spring and is electrically conductive, and the other of the first circuit and the second circuit is spaced apart from the other end of the spring.

[0135] By adopting the above scheme, the moving part 60 can be separated from the shell 30 so that the moving part 60 can move toward the direction close to the circuit board 40 and push the conductive part 50 under the drive of the elastic part 70, so that the spring sheet is elastically deformed, so that one of the first circuit and the second circuit is connected to one end of the spring sheet and electrically conductive, and the other of the first circuit and the second circuit is connected to the other end of the spring sheet and electrically conductive.

[0136] For example, the spring sheet has a first end and a second end, the first circuit is connected to the first end and is electrically conductive, and the second circuit is spaced apart from the second end. When the moving member 60 is driven by the elastic member 70 to move toward the circuit board 40, it can push the second end of the spring sheet to be connected to the second circuit and be electrically conductive, thereby achieving conductivity between the first circuit and the second circuit.

[0137] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Fig.11 , Fig.12 and Fig. 20On the other hand, an embodiment of the present application provides an aerosol generating device 100, including a power supply 10, an atomizing assembly 20 and the on-off assembly of the above-mentioned circuit board 40.

[0138] The aerosol generating device 100 provided in the embodiment of the present application has a circuit board 40 disposed inside the shell 30. The circuit board 40 includes a first circuit and a second circuit arranged at intervals. The first circuit is used to be electrically connected to the power supply 10, and the second circuit is used to be electrically connected to the atomizer assembly 20. The elastic member 70 is used to apply an elastic force toward the circuit board 40 to the moving member 60. The moving member 60 is connected to the shell 30 to limit the movement of the moving member 60 toward the circuit board 40. Therefore, during transportation or under bumpy conditions, the first circuit and the second circuit arranged at intervals can prevent the power supply 10 and the atomizer assembly 20 from being electrically connected, thereby avoiding the problem of self-starting of the atomizer assembly 20.

[0139] Furthermore, since the moving part 60 can be separated from the shell 30, the moving part 60 can be driven by the elastic part 70 to move toward the direction close to the circuit board 40 and push the conductive part 50, and electrically connect the first circuit and the second circuit through the conductive part 50, so that the power supply 10 and the atomization assembly 20 can be electrically connected through the conductive part 50 during normal use, thereby ensuring the normal use of the aerosol generating device 100.

[0140] It is understandable that the aerosol generating device 100 may also include a nozzle, supporting silicone, top silicone, a fixed bracket, oil-absorbing cotton, an air intake bracket, an oil filling plug, a sealing ring, an air intake bracket, battery foam, etc. The circuit board 40 can be installed on the fixed bracket by snap-fitting, which will not be repeated here.

[0141] Optionally, the shell 30 is also provided with a liquid storage chamber 302, in which a liquid aerosol generating matrix is ​​provided; the atomization component 20 includes a liquid inlet hole 201, which is isolated from the liquid storage chamber 302. When the moving part 60 is driven by the elastic part 70 to move toward the direction close to the circuit board 40 and push the conductive part 50, it can push the atomization component 20 together, so that the liquid inlet hole 201 is connected to the liquid storage chamber 302.

[0142] By adopting the above scheme, the aerosol generating matrix can be separated from the atomizing assembly 20 during transportation or under bumpy conditions, so as to prevent the aerosol generating matrix from entering the atomizing assembly 20. After the moving part 60 is separated from the shell 30, the moving part 60 is driven by the elastic part 70 to move toward the direction close to the circuit board 40 and push the conducting part 50, and can push the atomizing assembly 20 together, so that the liquid inlet hole 201 is connected with the liquid storage chamber 302, thereby ensuring the normal use of the aerosol generating device 100.

[0143] It can be understood that after the moving part 60 is separated from the shell 30, the moving part 60 moves toward the direction close to the circuit board 40 under the drive of the elastic part 70 and pushes the conductive part 50, which can push the atomizer assembly 20 together, so that the power supply 10 and the atomizer assembly 20 are electrically conductive, and the liquid inlet hole 201 is connected to the liquid storage chamber 302, thereby realizing the activation of the aerosol generating device 100.

[0144] Optionally, the aerosol generating device 100 further includes a sealing member 90, the sealing member 90 is provided with a through hole 901, the atomizing assembly 20 is movably arranged in the through hole 901, and the orifice of the liquid inlet hole 201 is located in the through hole 901, the sealing member 90 isolates the liquid inlet hole 201 and the liquid storage chamber 302, and the moving member 60 pushes the atomizing assembly 20 to move the orifice of the liquid inlet hole 201 into the liquid storage chamber 302, so that the liquid inlet hole 201 is connected with the liquid storage chamber 302.

[0145] With such a configuration, the liquid inlet hole 201 and the liquid storage chamber 302 can be better isolated by the sealing member 90 , and the liquid inlet hole 201 and the liquid storage chamber 302 can be easily connected.

[0146] For example, the sealing member 90 may include sealing silicone or the like.

[0147] Optionally, a plurality of liquid inlet holes 201 are provided and the plurality of liquid inlet holes 201 are arranged at intervals.

[0148] With such arrangement, after the liquid inlet hole 201 is connected to the liquid storage chamber 302 , the aerosol-generating matrix in the liquid storage chamber 302 can enter the interior of the atomization assembly 20 through the liquid inlet hole 201 more quickly.

Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
