For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood by specific circumstances.

[0064] like Figures 1 to 7 As shown, an embodiment of the utility model discloses an electrode connection structure for an atomizer, the electrode connection structure includes a circuit board 10 and a trigger assembly 11, the trigger assembly 11 includes a trigger member 110, specifically:

[0065] like Figure 8 As shown, the circuit board 10 includes an electrode movable part 100 and an electrode static contact 101. The trigger component 11 has a first working state (eg Figure 2 , Figure 3 and Figure 4 As shown) and the second working state (as Figure 5 , Figure 6 and Figure 7 It should be noted that the working state refers to the change state of the position and connection relationship.

[0066] When the trigger assembly 11 is in the first working state, the trigger member 110 is isolated from the electrode movable member 100 , and the electrode movable member 100 is disconnected from the electrode static contact 101 .

[0067] When the trigger assembly 11 is in the second working state, the trigger member 110 moves toward the electrode movable member 100 and presses against the electrode movable member 100 , so that the electrode movable member 100 and the electrode static contact 101 are in contact and conductive.

[0068] In this embodiment, the trigger component 11 is used to control the disconnection or contact between the electrode movable part 100 and the electrode static contact 101 on the circuit board 10, thereby controlling the power on and off, thereby achieving the function of preventing false triggering.

[0069] In some embodiments, the circuit board 10 is a PCB board, the electrode movable part 100 is a metal electrode spring, and the electrode static contact 101 is a solder joint. The PCB board, metal electrode spring and solder joint here are only examples and are not intended to limit the present application.

[0070] In some embodiments, the electrode connection structure further includes a first shell 121. Figures 2 to 7 As shown, the circuit board 10 is disposed inside the first housing 121, and the trigger assembly 11 further includes an elastic member 111 and a stop member 112. Specifically:

[0071] The trigger member 110 includes an abutting platform 1101 and a limiting portion 1102. The abutting platform 1101 includes a first end face 1101a and a second end face 1101b opposite to each other in the axial direction. The first end face 1101a is opposite to the electrode movable member 100. The limiting portion 1102 is arranged on the second end face 1101b and extends in a direction away from the abutting platform 1101. The first housing 121 is provided with a through hole 1211 corresponding to the limiting portion 1102. Fig.10 and Fig.11 As shown, for example, a through hole 1211 is provided at the bottom of the first shell 121 .

[0072] One end of the elastic member 111 abuts against the inner wall surface of the first shell 121, and the other end of the elastic member 111 abuts against the second end surface 1101b of the abutting platform 1101. The elastic member 111 is in a compressed state (eg Figure 2 , Figure 3 and Figure 4 ) and normal state (as shown Figure 5 , Figure 6 and Figure 7 The limiting member 112 is located outside the first housing 121 and serves as a component that can be installed and removed.

[0073] Among them, Figure 2 , Figure 3 and Figure 4 As shown, when the elastic member 111 is in a compressed state, the limiting member 112 , the limiting portion 1102 and the first shell 121 cooperate with each other to limit the trigger member 110 , so that the first end surface 1101 a of the abutting platform 1101 is isolated from the electrode movable member 100 .

[0074] like Figure 5 , Figure 6 and Figure 7 As shown, when the elastic member 111 is in a normal state, the first end surface 1101 a of the contact platform 1101 moves toward the direction close to the electrode movable member 100 and presses the electrode movable member 100 .

[0075] In some embodiments, Fig.12 and Fig.13 As shown, the limiting member 112 includes a limiting bone 1121. The limiting portion 1102 is at least two elastic arms, and a slot 1103 is provided between the elastic arms. A first buckle 1102a is provided at one end of the elastic arm away from the abutting platform 1101. Fig.11 As shown, at least two second buckles 1211a corresponding to the first buckles 1102a are provided on the inner wall surface of the through hole 1211. The at least two may be two, three or any number, which is not limited here.

[0076] Among them, Figure 3 and Figure 4 As shown, when the elastic member 111 is in a compressed state, the first buckle 1102a and the second buckle 1211a form an interference fit, and the limiting bone 1121 is inserted into the slot 1103 to limit the deformation of the elastic arm, so that the first buckle 1102a and the second buckle 1211a form a deadlock fit.

[0077] Specifically, when the first buckle 1102a is connected to the second buckle 1211a, the trigger member 110 tends to be deformed toward the slot 1103 and disengage from the second buckle 1211a due to the force of the elastic member 111, and the limiting bone 1121 is inserted into the slot 1103. The limiting bone 1121 can support the elastic arm, so that the elastic arm cannot continue to bend and deform, thereby forming a dead lock fit between the first buckle 1102a and the second buckle 1211a. At this time, even under the force of the elastic member 111, the trigger member 110 cannot be pushed, so that the electrode movable member 100 is not pressed by the first end face 1101a of the abutting platform 1101, so that the electrode movable member 100 remains disconnected from the electrode static contact 101, so the power is kept off and there is no output.

[0078] When the user removes the limit member 112, the trigger member 110, due to the force of the elastic member 111, will drive the elastic arm to bend and deform in the direction of the slot 1103, thereby breaking away from the interference of the second buckle 1211a, causing the trigger member 110 to move in the elastic direction of the elastic member 111, and then the first end face 1101a of the abutting platform 1101 will press the electrode movable member 100, so that the electrode movable member 100 is in contact with the electrode static contact 101 and is connected, thereby controlling the power output.

[0079] In some embodiments, Fig.13 As shown, the limiting member 112 also includes a patch 1122, and the limiting bone 1121 is arranged on the patch 1122. When the limiting bone 1121 is inserted into the slot 1103, the patch 1122 is attached to the outer wall surface of the first shell 121 to hide the limiting bone 1121 and the through hole 1211, and it is also convenient for the user to remove the limiting bone 1121 by removing the patch 1122 to complete the triggering action.

[0080] In some other embodiments (not shown), a socket is provided on one end of the limiting portion 1102 away from the abutting platform 1101, and the opening direction of the socket is perpendicular to the extension direction of the limiting portion 1102. When the elastic member 111 is in a compressed state, the socket is located outside the first shell 121, and the limiting member 112 is inserted into the socket, and under the action of the elastic member 111, the limiting member 112 forms an interference fit with the outer wall surface of the first shell 121 to lock the main body. For example, the limiting portion 1102 is a column, and the limiting member 112 is a sheet or a column. The sheet or column here is only an example and is not intended to limit the present application.

[0081] In some embodiments, the elastic member 111 is a spring. For the installation and positioning of the spring, Fig.10 As shown, a positioning column 1212 is provided on the inner wall surface of the first shell 121 , one end of the spring is sleeved on the positioning column 1212 , a through hole 1211 is provided on the positioning column 1212 , and the limiting portion 1102 is penetrated in the spring.

[0082] Accordingly, if Figures 2 to 7 As shown, the trigger member 110 further includes a positioning wall 1105 disposed on the second end surface 1101 b of the abutting platform 1101 in the circumferential direction, and the positioning wall 1105 is disposed around the other end of the spring.

[0083] In one usage scenario, for an atomizer with a wick separation, the user mistakenly starts the product before the wick separation is activated, resulting in the product wick sticking. Figures 1 to 7 As shown, an embodiment of the utility model discloses an atomizer 1, including the electrode connection structure described in the above embodiment, which will not be repeated here. The atomizer 1 can be used to store and heat atomize liquid aerosols such as liquid medicine to generate substrates, and to guide the aerosols out.

[0084] The atomizer 1 further comprises: an atomizer core assembly 13 and a liquid storage space 14 for storing a liquid aerosol generating matrix. The trigger assembly 11 is arranged at one end of the atomizer core assembly 13 , for example, the trigger assembly 11 is arranged at one axial end of the atomizer core assembly 13 , and the axial direction of the atomizer core assembly 13 is consistent with the axial direction A of the atomizer 1 .

[0085] The atomizer core assembly 13 includes an atomizer core, a liquid guide member surrounding the atomizer core, and a heating element disposed on the atomizer core. When in use, the atomizer core absorbs the liquid aerosol-generating matrix in the liquid storage space 14 through the liquid guide member, and the heating element is energized to generate heat, so that the liquid aerosol-generating matrix in the atomizer core is atomized. The user inhales through the suction port of the atomizer 1, and the air enters the atomizer core from the air inlet channel of the atomizer 1 under the action of suction force, mixes with the atomized aerosol in the atomizer core, and is discharged from the suction port after passing through the air outlet channel 1221 of the atomizer 1.

[0086] Among them, Figure 2 , Figure 3 and Figure 4 As shown, when the trigger assembly 11 is in the first working state, the atomizer core assembly 13 is isolated from the liquid storage space 14 .

[0087] like Figure 5 , Figure 6 and Figure 7 As shown, when the trigger assembly 11 is in the second working state, the trigger member 110 pushes the atomizer core assembly 13 to connect the atomizer core assembly 13 with the liquid storage space 14 .

[0088] This embodiment combines the anti-false triggering function with the oil core separation function of the atomizer, and synchronously controls the isolation or connection of the atomizer core assembly 13 and the liquid storage space 14 through the trigger assembly 11. Specifically, when the electrode movable part 100 is disconnected from the electrode static contact 101, the atomizer core assembly 13 is isolated from the liquid storage space 14. When the electrode movable part 100 is in contact with the electrode static contact 101, the atomizer core assembly 13 is connected to the liquid storage space 14 under the push of the trigger member 110, thereby achieving consistency in the activation of the start and the oil core separation, and avoiding the problem of the product being accidentally started and used before the oil core separation is activated, resulting in the problem of the product sticking.

[0089] The circuit board 10 and the trigger assembly 11 are located in the axial direction A of the atomizer 1 , and the axial direction of the abutting platform 1101 is consistent with the axial direction A of the atomizer 1 . In some other embodiments, the circuit board 10 and the trigger assembly 11 may also be located in the radial direction of the atomizer 1 .

[0090] In addition, if Figures 2 to 7 As shown, the trigger member 110 further includes a pushing portion 1104 for pushing the atomizer core assembly 13 . The pushing portion 1104 is disposed on the first end surface 1101 a of the abutting platform 1101 and extends in a direction away from the abutting platform 1101 .

[0091] In some embodiments, the atomizer 1 further includes a controller and an airflow sensor, and the controller is used to control the power on and off by detecting whether the electrode movable part 100 is in contact and conduction with the electrode static contact 101 and detecting whether the airflow sensor senses the change in internal air pressure. When the controller detects that the electrode movable part 100 is in contact and conduction with the electrode static contact 101, and detects that the airflow sensor senses the change in internal air pressure, it controls the power on output. When the controller detects that the electrode movable part 100 is disconnected from the electrode static contact 101, or detects that the airflow sensor does not sense the change in internal air pressure, it controls the power off and no output. It should be noted that the controller can be set not only on the circuit board 10, but also on other components, such as integrated on the airflow sensor (microphone), and integrally formed with the airflow sensor, which is not specifically limited here.

[0092] In some embodiments, Figures 2 to 7 As shown, the atomizer 1 further includes an atomizer core base 15 , which is located between the atomizer core assembly 13 and the trigger member 110 , and the trigger member 110 pushes the atomizer core assembly 13 through the atomizer core base 15 .

[0093] In some embodiments, Fig. 9 As shown, the atomizer core assembly 13 includes a liquid inlet hole 131 for liquid to enter from the liquid storage space 14. Figures 2 to 7 As shown, the atomizer 1 further includes a first sealing sleeve 16 , which is sleeved on the periphery of the atomizing core assembly 13 , and the first sealing sleeve 16 constitutes a side wall of the liquid storage space 14 .

[0094] Among them, Figure 2 , Figure 3 and Figure 4 As shown, when the trigger assembly 11 is in the first working state, the first sealing sleeve 16 is opposite to the liquid inlet hole 131 , and the liquid inlet hole 131 is isolated from the liquid storage space 14 .

[0095] like Figure 5 , Figure 6 and Figure 7 As shown, when the trigger assembly 11 is in the second working state, the trigger member 110 (pushing portion 1104 ) pushes the atomizer core assembly 13 , so that the liquid inlet hole 131 moves relative to the first sealing sleeve 16 and is misaligned with the first sealing sleeve 16 , and the liquid inlet hole 131 is connected to the liquid storage space 14 .

[0096] In its entirety, the atomizer 1 further comprises a housing 12, and the housing 12 comprises a first shell 121 and a second shell 122. The atomizer 1 further comprises a second sealing sleeve 17, which is also sleeved on the periphery of the atomizer core assembly 13, and the first sealing sleeve 16 and the second sealing sleeve 17 are opposite in the axial direction of the atomizer core assembly 13, and the second sealing sleeve 17 also constitutes a side wall of the liquid storage space 14, so the atomizer core assembly 13, the first sealing sleeve 16, the second sealing sleeve 17 and the second shell 122 jointly define the liquid storage space 14. For example, the first sealing sleeve 16 and the second sealing sleeve 17 are silicone sealing sleeves, and the silicone sealing sleeves here are only examples and are not intended to limit the present application.

[0097] In some embodiments, Figure 2 , Figure 3 and Figure 4 As shown, the other end of the atomizer core assembly 13 is provided with an activity space 171. Specifically, the other end of the atomizer core assembly 13 is provided with an activity space 171 inside the shell 12 (second shell 122). The atomizer core assembly 13 can move in the activity space 171 when being pushed.

[0098] Among them, one end and the other end of the atomizer core assembly 13 are two opposite ends in its axial direction. Specifically, the housing 12 (the second housing 122) is provided with an air outlet channel 1221, the atomizer core assembly 13 also includes an air outlet 132, the air outlet 132 is connected to the air outlet channel 1221, the second sealing sleeve 17 includes an air inlet hole 172 and an air outlet hole 173, the air outlet 132 of the atomizer core assembly 13 is inserted into the second sealing sleeve 17 from the air inlet hole 172, and the air outlet hole 173 of the second sealing sleeve 17 is connected to the air outlet channel.

[0099] like Figure 2 , Figure 3 and Figure 4 As shown, when the trigger assembly 11 is in the first working state, there is a movable space 171 between the air outlet 132 of the atomizer core assembly 13 and the air outlet hole 173 of the second sealing sleeve 17 .

[0100] like Figure 5 , Figure 6 and Figure 7 As shown, when the trigger assembly 11 is in the second working state, the trigger member 110 (pushing portion 1104) pushes the atomizer core assembly 13, so that the air outlet 132 of the atomizer core assembly 13 moves in the activity space 171 toward the direction close to the air outlet hole 173 of the second sealing sleeve 17, so that the atomizer core assembly 13 (liquid inlet 131) is connected with the liquid storage space 14, for example, the air outlet 132 moves to the air outlet hole 173.

[0101] An embodiment of the utility model discloses an electronic atomization device, including a power supply device 2 and the atomizer 1 described in the above embodiment, which is not described in detail here. The power supply device 2 is used to supply power to the atomizer 1, specifically, two heating wire pins of the atomization core assembly 13 are welded on the circuit board 10, and the positive and negative electrodes of the power supply device 2 are also welded on the circuit board 10. When the controller detects that the electrode movable part 100 is in contact with the electrode static contact 101 and detects that the airflow sensor senses a change in internal air pressure, the power supply device 2 is controlled to supply power.

[0102] By implementing the utility model, the following beneficial effects are achieved:

[0103] The utility model controls the disconnection or contact between the electrode movable part and the electrode static contact on the circuit board through the trigger component, thereby controlling the power on and off, thereby achieving the function of preventing false triggering. In addition, the operation of the false trigger prevention is simple and convenient, does not increase the user's learning cost, and can improve the use experience.

[0104] At the same time, the anti-false triggering function is combined with the oil core separation function of the atomizer, and the isolation or connection between the atomizer core assembly and the liquid storage space is synchronously controlled through the trigger assembly. Specifically, when the electrode movable part is disconnected from the electrode static contact, the atomizer core assembly is isolated from the liquid storage space. When the electrode movable part is in contact with the electrode static contact, the atomizer core assembly is connected to the liquid storage space under the push of the trigger, thereby achieving consistency in the activation of the start and the oil core separation, which can avoid the problem of the product being accidentally started and used before the oil core separation is activated, resulting in the problem of the product sticking.
