An electronic atomization device 10 provided in an embodiment of the present application includes an upper cover module 100, a positioning module 200, an atomization module 300 and a power module 400.

[0047] The upper cover module 100 is provided with a suction port 140. In the specific configuration, the upper cover module 100 includes an upper shell 110 and a suction nozzle 120 and a docking tube 130 respectively arranged on the upper and lower sides of the upper shell 110. The suction port 140 penetrates the suction nozzle 120 and the docking tube 130 so that the suction nozzle 120 is connected with the docking tube 130. The positioning module 200 includes a positioning member 210 and a limiting groove 220 adapted to the positioning member 210. The positioning member 210 can be deformed along its own axial direction and arranged on one of the upper cover module 100 and the atomization module 300, and the limiting groove 220 is arranged on the other of the two. The present application is illustrated with the positioning member 210 arranged on the upper cover module 100 and the limiting groove 220 arranged on the atomization module 300. The atomizer module 300 can be rotatably installed around its own axis between the upper cover module 100 and the power module 400. When the atomizer module 300 rotates to the position where the positioning member 210 and the limiting groove 220 are locked, the atomizer module 300 is connected to the inhalation port 140 and electrically connected to the power module 400. In the specific setting, in order to facilitate the rotation of the atomizer module 300, the electronic atomizer device of the positioning structure also includes a housing 500 with a accommodating chamber 510, and the accommodating chamber 510 is used to install the upper cover module 100, the atomizer module 300 and the power module 400. The housing 500 is also provided with an operating window 520 connected to the accommodating chamber 510, and the operating window 520 is used for the user to rotate the atomizer module 300.

[0048] It should be noted that when the atomizer module 300 is connected to the suction port 140 and electrically connected to the power module 400, the power module 400 supplies power to the atomizer module 300, so that the atomizer module 300 heats the atomized liquid stored in itself into an aerosol, and provides it for the user to inhale through the suction port 140. It should be emphasized that during the rotation of the atomizer module 300, the positioning member 210 located between the atomizer module 300 and the upper cover module 100 is in a compressed state. When the atomizer module 300 rotates to the positioner 210 and the limiting groove 220 facing each other, the positioner 210 recovers its deformation under the action of its own rebound force and is located in the limiting groove 220 to achieve positioning; when it is necessary to unlock the positioner 210 and the limiting groove 220, continue to rotate the atomizer module 300, so that the positioner 210 is deformed and thus disengaged from the limiting groove 220.

[0049] The above-mentioned electronic atomization device 10 includes a positioning member 210 and a limiting groove 220 by setting a positioning module 200. The positioning member 210 can be set on one of the upper cover module 100 and the atomization module 300 along its own axial deformation, and the limiting groove 220 is set on the other of the two. In the process of rotating the atomization module 300, when the atomization module 300 rotates to the point where the positioning member 210 and the limiting groove 220 cooperate and lock, the atomization module 300 is connected to the inhalation port 140 and electrically connected to the power module 400, and the electronic atomization device 10 works normally to generate aerosol for the user to inhale. It is ensured that the atomization module 300 moves to the target position, and the electronic atomization device 10 works, ensuring the stability of the work.

[0050] When the atomizing module 300 is rotated, in order to facilitate the positioning member 210 to move smoothly before rotating to the limiting groove 220, a preferred embodiment, the positioning module 200 also includes a slide groove 230, the slide groove 230 is used to provide a sliding track for the positioning member 210, the slide groove 230 is arranged on one of the upper cover module 100 and the atomizing module 300, the positioning member 210 is arranged on the other of the two, and the positioning member 210 is slidably arranged on the slide groove 230, and the limiting groove 220 opens at the bottom of the slide groove 230 and is used to accommodate the positioning member 210. It should be noted that when the slide groove 230 is arranged on the upper cover module 100, the slide groove 230 is opened at the lower end of the upper shell 110, and the positioning member 210 is arranged on the upper side of the atomizing module 300; when the slide groove 230 is arranged on the atomizing module 300, the slide groove 230 is opened at the upper end of the atomizing module 300, and the positioning member 210 is arranged on the lower side of the upper shell 110. Through the above-mentioned arrangement, when the atomization module 300 is rotated, the positioning member 210 moves relative to the slide groove 230. The positioning member 210 is in a compressed state during the movement relative to the slide groove 230 until the positioning member 210 moves to the limiting groove 220 opening at the bottom of the slide groove 230, and the positioning member 210 restores its deformation and is fixed in the limiting groove 220.

[0051] As shown in FIG. 5 , FIG. 5 is a cross-sectional view of a positioning member 210 in an embodiment of the present application. In some embodiments, in order to design the positioning member 210 more conveniently, a preferred embodiment is that the positioning member 210 includes an elastic member 211 and a positioning bead 212 connected to one end of the elastic member 211, and the end of the elastic member 211 away from the positioning bead 212 is arranged on one of the upper cover module 100 and the atomization module 300. In a specific setting, the positioning member 210 also includes a positioning shell 213, one end of the positioning shell 213 has a notch, and the other end of the positioning shell 213 is arranged on one of the upper cover module 100 and the atomization module 300, and the end of the elastic member 211 away from the positioning bead 212 is installed in the positioning shell 213, and the end of the positioning bead 212 away from the elastic member 211 is adapted to the notch of the positioning shell 213, and the elastic member 211 is generally arranged as a spring. Through the above arrangement, when the atomization module 300 rotates, the positioning bead 212 in the positioning member 210 moves relative to the slide groove 230, and until the positioning bead 212 moves to the limiting groove 220 opening at the bottom of the slide groove 230, the elastic member 211 restores its deformation so that the positioning bead 212 is fixed in the limiting groove 220, thereby achieving positioning.
