In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

In the description of the present invention, it is to be understood that the terms "central," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the invention and to simplify the description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are not to be considered limiting of the invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In the present invention, unless otherwise expressly stated or limited, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through an intermediate. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. As used herein, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and the like are for purposes of illustration only and do not denote a single embodiment.

As described in the background art, the yield of the key mechanism in the related art is low, and the problem of loosening or locking is easily caused. The inventor researches and finds that the root cause of the problem is that when the key mechanism is assembled, each element has tolerance in the pressing direction, for example, when the length of the press rod in the switch is short, the key which is assembled outside the press rod and used for triggering the press rod cannot be supported by the press rod in a natural state without being pressed, and the phenomenon of looseness occurs. For another example, when the length of the pressing rod in the switch is long, the button is limited on the shell through the flange on the periphery, and then the long pressing rod is extruded, so that the pressing rod is always in a pressed state and cannot be reset, and the button is dead pushed. These problems ultimately affect the yield of the key mechanism and the processing efficiency.

In order to solve the above technical problem, referring to fig. 1, in an embodiment of the present invention, an electronic atomizer 200 is provided, which includes a main body 210 and a key mechanism 100, the main body 210 is used for heating an aerosol-generating substrate, the key mechanism 100 is disposed on the main body 210 and is operable to control an operating state of the main body 210, such as turning on or off a power supply in the main body 210, or adjusting a heating temperature, and the specific control purpose of the key mechanism 100 is not limited herein.

Referring to fig. 2-3, the electronic atomizer 200 further includes a housing 10, the housing 10 is disposed outside the main body 210 and has a mounting hole 11, and the key mechanism 100 is mounted at the mounting hole 11 of the housing 10. Specifically, the key mechanism 100 includes a switch assembly 30 and a pressing assembly 50, the switch assembly 30 is fixedly disposed on the main body 210, and the pressing assembly 50 is disposed through the mounting hole 11 and magnetically connected to the switch assembly 30. Moreover, the projection of the pressing member 50 toward the housing 10 is completely located in the mounting hole 11, so that the cross section of the pressing member 50 is equal to or smaller than the cross section of the mounting hole 11, and the whole pressing member 50 can move freely in the axial direction of the mounting hole 11.

In the process of installing the key mechanism 100, firstly, the switch component 30 is fixed on the main body 210, then the shell 10 is sleeved outside the main body 210, the switch component 30 is exposed out of the mounting hole 11 on the shell 10, finally, the pressing component 50 is sleeved outside the shell 10 and is arranged in the mounting hole 11, the pressing component 50 is connected with the switch component 30 through magnetic attraction, the key mechanism 100 is assembled in this way, the pressing component 50 does not need to be installed inside the shell 10, and the installation process is simple.

In addition, it is not necessary to set a limit flange on the periphery of the pressing component 50, and the pressing component 50 is connected with the switch component 30 through magnetic attraction, so that the interference of the extension and retraction amplitude of the pressing component 50 by the shell 10 is avoided, and the pressing component 50 can adapt to different dimensional tolerances of the switch component 30 in the pressing direction, so that the pressing component 50 and the switch component 30 are effectively assembled. For example, when the switch assembly 30 has a small size in the pressing direction, the pressing assembly 50 can still be stably assembled on the switch assembly 30 under the action of the magnetic attraction force, so that the pressing assembly 50 can be prevented from loosening; for example, when the switch module 30 is large in size in the pressing direction and the pressing rod of the switch module 30 is long, the pressing module 50 is adaptively moved outward by a certain distance and then attracted to the switch module 30, so that the switch module 30 is not always pressed at a position close to the switch module 30, and the key and the switch module 30 are prevented from being stuck and being unable to be reset. Therefore, the pressing component 50 can be compatible with different tolerances of the switch component 30 in the pressing direction, and the pressing component 50 and the switch component 30 can be assembled in an adaptive manner, so that the pressing component 50 is prevented from loosening or being stuck, and the installation yield and the production efficiency of the pressing component 50 and the switch component are improved.
