DETAILED DESCRIPTION

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used in the specification herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the description and claims of the application as well as the above abstract are intended to cover all alternatives, modifications, and equivalents of the application falling within the scope of the application. The terms "comprising", "having", "including", and "containing" used herein are meant to be interpreted in a non-limiting manner.

[0040] ​​​​​In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0041] This application provides an anti-misunderstanding lock structure. In application, this anti-misunderstanding lock structure is installed on the housing 300 of the atomizer to fix the atomizing core 200 inside the housing 300 of the atomizer. (See reference...) Figures 1 to 14 The anti-misunderstanding lock structure includes a first locking tongue 110, a fixing frame 120, and a switch slide 130.

[0042] The first locking tongue 110 is connected to the switch slide 130. The fixing bracket 120 is fixedly connected to the housing 300 of the atomizer. The switch slide 130 is movably connected to the fixing bracket 120. Under the action of external force, the switch slide 130 moves back and forth relative to the fixing bracket 120 in the first direction and cooperates with the fixing bracket 120 to lock and unlock the movement of the first locking tongue 110 in the second direction. Under the action of external force, the first locking tongue 110 moves back and forth relative to the fixing bracket 120 in the second direction to lock and unlock the position of the atomizing core 200. The first direction and the second direction are not parallel to each other.

[0043] Understandably, the working principle of this anti-misunderstanding lock structure is as follows:

[0044] When the user needs to remove the atomizing coil 200 that was originally installed in the housing 300 of the atomizer (e.g.) Figures 9 to 11 As shown), by applying external force to the switch slide 130, the switch slide 130 can be moved in the first direction and released from the fixing bracket 120, thereby unlocking the movement of the first locking tongue 110 in the second direction (as shown). Figures 12 to 13 As shown), at this time, the first locking tongue 110 can move along the second direction under the application of external force. After the first locking tongue 110 moves along the second direction, the atomizing core 200 is unlocked (as shown). Figures 12 to 13 As shown), the atomizer coil 200 can be detached from the atomizer housing 300; when it is necessary to install the atomizer coil 200 into the atomizer housing 300 (as shown), Figure 14 As shown, first, the atomizing core 200 is placed into the housing 300 of the atomizer. Then, the first locking tongue 110 is moved in the opposite direction of the second direction by external force to lock the position of the atomizing core 200. Then, the switch slide 130 is moved in the opposite direction of the first direction so that the switch slide 130 cooperates with the fixing bracket 120 to lock the first locking tongue 110 moving in the second direction. The first locking tongue 110 is in a locked state, and at the same time, the atomizing core 200 can be kept locked.

[0045] Since the atomization core 200 is controlled to be unlocked by the first locking tongue 110, when the atomization core 200 and the first locking tongue 110 are both in the locked state, the user needs to first unlock the first locking tongue 110 through the switch sliding buckle 130, and then unlock the atomization core 200 through the first locking tongue 110.

[0046] Compared with the prior art, the anti-misoperation unlocking structure has at least the following technical effects:

[0047] The present application realizes double locking of the atomization core 200 by setting the switch sliding buckle 130 to cooperate with the fixed frame 120 to lock the first locking tongue 110, and by setting the first locking tongue 110 to lock the atomization core 200. The first direction and the second direction are not parallel to each other, and the user must operate in a preset trajectory (i.e., the first direction plus the second direction) to realize unlocking of the atomization core 200, thereby avoiding misoperation of children or accidental touch of the atomizer by foreign objects, and preventing the atomization core 200 from being pulled out of the atomizer shell 300 to cause leakage of the aerosol generating substrate.

[0048] It should be noted that the first direction and the second direction are any two directions that are not parallel to each other in the same plane. In the present application, the first direction is the direction for unlocking the first locking tongue 110, and the second direction is the direction for unlocking the atomization core 200. The opposite direction of the first direction is the direction for locking the first locking tongue 110, and the second direction is the direction for locking the atomization core 200. Of course, the first direction and the second direction can be set according to actual needs, and the present application does not make specific limitations in this regard.

[0049] In one embodiment, the anti-misoperation unlocking structure further includes an elastic member 140, both ends of the elastic member 140 are connected with the first locking tongue 110 and the shell 300 of the atomizer, and the elastic member 140 is used to provide elastic force for the first locking tongue 110 to lock the atomization core 200. Specifically, in the free state of the elastic member 140, the first locking tongue 110 protrudes from the shell to clamp the atomization core 200, thereby realizing locking of the atomization core 200. When the first locking tongue 110 moves in the second direction under the action of external force, the elastic member 140 is compressed, and the elastic member 140 always provides elastic force in the direction opposite to the second direction to the first locking tongue 110, so that the user needs to always overcome the elastic force of the elastic member 140 to realize unlocking of the atomization core 200. That is, when the user unlocks the atomization core 200, the user needs to always press the switch sliding buckle 130 and always apply force in the direction opposite to the second direction to the switch sliding buckle 130 to take out the atomization core 200 from the shell 300 of the atomizer. By setting the elastic member 140, the present embodiment further increases the difficulty of unlocking the atomization core 200, thereby improving the effect of preventing misoperation of unlocking the atomization core 200.

[0050] In the embodiment, the elastic member 140 is a spring. In other embodiments, the elastic member 140 can also be a spring piece or a flexible piece capable of providing elastic force.

[0051] Referring to Figures 1 to 4 In the embodiment, the first lock tongue 110 is provided with a positioning protrusion 111 protruding towards the elastic member 140 at one end close to the elastic member 140. The elastic member 140 is sleeved on the outer periphery of the positioning protrusion 111. The positioning protrusion 111 limits the position of the elastic member 140, avoiding displacement of the elastic member 140 in use.

[0052] Referring to Figures 1 to 15 In one embodiment, the anti-misoperation locking structure further comprises a switch seat 150. The switch seat 150 is connected with the first lock tongue 110. The switch seat 150 is movably connected with the fixed frame 120. The switch seat 150 can reciprocate along the second direction relative to the fixed frame 120 to drive the first lock tongue 110 to move. The switch sliding buckle 130 is movably connected with the switch seat 150. The switch sliding buckle 130 can reciprocate along the first direction relative to the switch seat 150 to lock and unlock the movement of the switch seat 150 along the second direction.

[0053] In the embodiment, the switch seat 150 serves as a connection between the first lock tongue 110 and the switch sliding buckle 130. When the switch sliding buckle 130 moves towards the first direction to be disconnected with the fixed frame 120, the movement of the switch seat 150 along the second direction is unlocked. The switch seat 150 can move along the second direction under the driving of the switch sliding buckle 130. When the switch sliding buckle 130 moves towards the opposite direction of the first direction to be connected with the fixed frame 120, the movement of the switch seat 150 along the second direction is locked. Since the switch seat 150 is connected with the first lock tongue 110, the first lock tongue 110 is also locked.

[0054] In the embodiment, the surface of the switch seat 150 is provided with an anti-skid groove. Specifically, the elastic member 140 connected with the first lock tongue 110 provides elastic force for the first lock tongue 110 in the direction of locking the atomizing core 200. When the atomizing core 200 needs to be unlocked, external force needs to be continuously applied to overcome the elastic force to realize the removal of the atomizing core 200. The anti-skid groove provided on the surface of the switch seat 150 can increase the friction between the switch seat 150 and the user's hand, facilitating the user to continuously apply external force to the switch seat 150.

[0055] In the embodiment, the top of the fixed frame 120 is provided with a groove 121, the switch base 150 and the switch sliding buckle 130 are located in the groove 121, the first locking tongue 110 is located at the bottom of the fixed frame 120, the switch base 150 is provided with a connecting rod 151, and the connecting rod 151 passes through the fixed frame 120 and is connected with the first locking tongue 110. Specifically, since the switch base 150 is installed in the groove 121, the switch base 150 can only move within the range of the groove 121, and the groove 121 can limit the moving direction and displacement of the switch base 150, wherein the length direction of the groove 121 is parallel to the second direction, so that the switch base 150 can move along the second direction relative to the fixed frame 120. Moreover, the limiting effect of the groove 121 on the switch base 150 also has a position limiting effect on the first locking tongue 110, so as to avoid the first locking tongue 110 from being pulled out of the atomizer.

[0056] In the embodiment, the side wall of the groove 121 is provided with an opening 122, the switch sliding buckle 130 is provided with a buckling part 1321 extending along the first direction, and the buckling part 1321 is clamped in the opening 122 to lock the movement of the first locking tongue 110 in the second direction. Specifically, the switch sliding buckle 130 can control the movement of the buckling part 1321 in the first direction under the action of an external force, so that the buckling part 1321 can be separated from or clamped in the opening 122 of the groove 121. When the buckling part 1321 is clamped in the opening 122, the first locking tongue 110 is in a locked state (as shown in Figures 5 to 8 When the buckling part 1321 is separated from the opening 122, the first locking tongue 110 is in an unlocked state (as shown in Figures 9 to 11 .

[0057] In the embodiment, the switch sliding buckle 130 includes a button 131 and a second locking tongue 132, the button 131 is connected to the switch base 150, the first end of the second locking tongue 132 is fixedly connected to the button 131 through the switch base 150, and the second end of the second locking tongue 132 is the buckling part 1321. In the embodiment, the second locking tongue 132 is connected to the button 131 through the switch base 150, so that the connection structure of the switch sliding buckle 130 and the switch base 150 is more compact, and the user only needs to apply an external force to the button 131 to realize the displacement control of the switch base 150 and the first locking tongue 110.

[0058] Based on the above-mentioned anti-misoperation locking structure, the application further provides an atomizer, as shown in Figure 15 , which comprises an atomizing core 200, a shell 300, and the anti-misoperation locking structure provided in the above-mentioned embodiments. The atomizing core 200 is detachably connected in the shell 300, and when the atomizing core 200 is connected in the shell 300, the first locking tongue 110 of the anti-misoperation locking structure abuts against the atomizing core 200 to lock the position of the atomizing core 200.

[0059] In one embodiment, the shell 300 comprises an upper cover 310 and a bottom cover 320, the upper cover 310 is connected to the top of the bottom cover 320, the atomization core 200 is connected to the bottom cover 320, and the upper cover 310, the bottom cover 320 and the atomization core 200 enclose the oil tank 301.

[0060] In one embodiment, the outer side of the atomization core 200 is provided with a flange 210 extending radially, the flange 210 is used to abut the first locking tongue 110 to lock the position of the atomization core 200.

[0061] In this embodiment, the atomizer further comprises a suction nozzle 400, which is connected to the shell 300 and is arranged correspondingly to the atomization core 200.

[0062] In this embodiment, the middle part of the shell 300 is provided with a mounting through hole 302, the atomization core 200 is connected to one end of the mounting through hole 302, and the suction nozzle 400 is connected to the other end of the mounting through hole 302. The locking tongue of the mistaken lock prevention structure can be extended into the mounting through hole 302 to abut and disengage the flange 210, thereby locking and unlocking the position of the atomization core 200.

[0063] In this embodiment, the mounting through hole 302 is also provided with an atomization core cover 500, when the atomization core 200 is connected to the mounting through hole 302, the atomization core cover 500 covers the outside of the atomization core 200 to limit the position of the atomization core 200 in the mounting through hole 302, so that the atomization core 200 remains stable after installation and is not easy to shake.
