[0009] The protective cover includes a cover portion and an insert portion connected to each other. The insert portion is installed in the mounting hole. A guide slope is formed on the side of the mounting hole away from the mounting groove. An abutment slope is formed on the outer edge of the cover portion. The abutment slope is in contact with the guide slope. The insert portion is provided with a plurality of buckle members. The plurality of buckle members are spaced apart along the circumference of the insert portion. The buckle members are used to fasten with the outer shell. The outer shell abuts against the buckle members and the abutment slope respectively.

[0010] In one embodiment, the end of the embedded portion opposite to the cover portion has a guide slope.

[0011] In one embodiment, the inner wall of the outer shell is provided with an abutment block, which is correspondingly fastened to one of the buckle members.

[0012] In one embodiment, each of the buckles has openings on both sides.

[0013] In one embodiment, the inverted protective cover structure further includes a button assembly. The protective cover has a button hole. The button assembly includes a button cap, a silicone part, and a contact switch. The contact switch is mounted on the panel. The silicone part covers the contact switch. A portion of the button cap passes through the button hole. The periphery of the button cap abuts against the inner wall of the protective cover. The button cap has a protruding abutting arm.

However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0028] 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 disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0030] like Figures 1 to 3 As shown, this is an embodiment of the inverted protective cover structure 10 of the present disclosure, including an outer shell 100, a protective cover 200, a panel 300 and an electrical base 400. The outer shell 100 has a mounting groove 101 and an assembly hole 102 communicating with the mounting groove 101. The electrical base 400 is installed inside the outer shell 100, and the panel 300 is fixed to the electrical base 400. The panel 300 is located below the assembly hole 102.

[0031] Furthermore, the protective cover 200 includes a cover portion 210 and an insert portion 220 connected to each other. The insert portion 220 is installed in the mounting hole 102. A guide slope 110 is formed on the side of the mounting hole 102 opposite to the mounting groove 101. An abutting slope 211 is formed on the outer edge of the cover portion 210. The abutting slope 211 is in corresponding contact with the guide slope 110. The insert portion 220 is provided with a plurality of buckle members 221. The plurality of buckle members 221 are arranged at intervals along the circumference of the insert portion 220. The buckle members 221 are used to fasten with the outer shell 100. The outer shell 100 abuts against the buckle members 221 and the abutting slope 211 respectively.

[0032] In this embodiment, the embedded part 220 below the protective cover 200 is designed with a plurality of circumferentially distributed buckles 221, which hook the outer shell 100 from below. The abutting slope 211 of the outer edge of the cover portion 210 on the upper part of the protective cover 200 abuts against the guide slope 110 of the edge of the mounting hole 102 of the outer shell 100. When the protective cover 200 is assembled with the outer shell 100, the assembly can be completed simply by pressing the protective cover 200 into the mounting hole 102. At this time, the guide slope 110 guides the abutting slope 211, so that the protective cover 200 is accurately positioned in the mounting hole 102. When the buckle 221 fastens the inside of the outer shell 100, the buckle 221 hooks the outer shell 100 upward, while the abutting slope 211 of the cover portion 210 presses the outer shell 100 downward, forming a stable structure in which the outer shell 100 is clamped between the buckle and the abutting slope 211. The protective cover 200 does not occupy the space at the bottom of the mounting groove 101, which increases the usable space of the panel 300.

[0033] The aforementioned snap-on protective cover structure 10 uses a guide slope 110 and an abutment slope 211 to provide initial positioning and clamping. The tight clamping of the abutment slope 211 and the guide slope 110 causes the outer shell 100 to be clamped between the snap-on part 221 and the abutment slope 211 of the protective cover 200, thereby ensuring a tight connection between the protective cover 200 and the outer shell 100. Installation can be completed simply by aligning the protective cover 200 with the mounting hole 102 and pressing it down. The assembly process is simple and improves assembly efficiency. The protective cover 200 is directly snapped onto the outer shell 100, saving space for the snap-on bracket, increasing the installation space of the panel 300, which is beneficial for increasing the screen ratio of the panel 300, and making the structure of the snap-on protective cover structure 10 more compact.

[0034] like Figure 4 As shown, in one embodiment, the end of the insert 220 facing away from the cover 210 has a guide slope 222. In this embodiment, during the installation process of aligning the protective cover 200 with the mounting hole 102, the guide slope 222 and the edge of the mounting hole 102 form a guiding effect, allowing the guide slope 222 to guide the insert 220 to slide quickly into the mounting hole 102, thereby reducing the installation difficulty and improving the assembly speed.

[0035] like Figure 1 As shown, in one embodiment, the inner wall of the outer shell 100 is provided with an abutment block 120, which is correspondingly engaged with a buckle 221. In this embodiment, the abutment block 120 is integrally formed with the outer shell 100, and the position of the abutment block 120 corresponds to the buckle 221. When the buckle 221 and the abutment block 120 are engaged, the movement of the protective cover 200 is further restricted, thereby improving the positioning accuracy, impact resistance, and assembly stability of the protective cover 200.

[0036] like Figure 4 As shown, in one embodiment, each of the aforementioned buckle members 221 has openings 2201 on both sides. In this embodiment, the buckle member 221 deforms and bends during installation, and the stress concentrates at the root, which can easily lead to fatigue fracture. By opening holes on both sides to release lateral stress, the buckle member 221 is less likely to fracture during deformation, thus extending its service life.

[0037] like Figure 2 and Figure 4As shown, in one embodiment, the inverted protective cover structure 10 further includes a button assembly 500. The protective cover body 200 has a button hole 201. The button assembly 500 includes a button cap 510, a silicone part 520, and a contact switch 530. The contact switch 530 is mounted on the panel 300. The silicone part 520 covers the contact switch 530. A portion of the button cap 510 passes through the button hole 201. The periphery of the button cap 510 abuts against the inner wall of the protective cover body 200. The button cap 510 has a protruding abutting arm 511. The abutting arm 511 abuts against the side of the silicone part 520 opposite to the contact switch 530. In this embodiment, the abutting arm 511 presses directly on the silicone part 520. When the button cap 510 is pressed, the force is transmitted to the silicone part 520 through the abutting arm 511, and then the silicone part 520 deforms to trigger the contact switch 530. The silicone part 520 is used to seal the contact switch 530, transmit the force and provide tactile feedback. The button cap 510 slides along the axial direction of the button hole 201, so that the position of the button cap 510 is fixed.

[0038] like Figure 4 As shown, in one embodiment, the silicone part 520 has a limiting groove 5201, and one end of the contact switch 530 is adapted to be embedded in the limiting groove 5201. In this embodiment, the limiting groove 5201 cooperates with the contact switch 530 to fix the silicone part 520 in the position of the contact switch 530, preventing the silicone part 520 from deviating. When the button cap 510 is pressed by an external force, it can accurately transmit the force to the corresponding trigger area on the silicone part 520, thereby fixing the relative position between the protective cover 200 and the button cap 510 and the silicone part 520.

[0039] like Figure 4 As shown, in one embodiment, the protective cover 200 further includes a first limiting block 230 and a second limiting block 240. The button cap 510 has a protruding positioning block 512, which passes between the first limiting block 230 and the second limiting block 240. In this embodiment, when the button cap 510 moves vertically along the direction of the button hole 201, the button cap 510 is prone to wobbling in the horizontal direction. By limiting the positioning block 512 through the first limiting block 230 and the second limiting block 240, the button cap 510 maintains vertical and stable movement during pressing, thereby reducing unnecessary friction between the button cap 510 and the inner wall of the button hole 201 caused by wobbling, reducing wear, and thus extending the service life of the button assembly and the protective cover 200.

[0040] like Figure 2As shown, in one embodiment, the electrical base 400 has a limiting and fixing groove 401, and the panel 300 is limited and installed in the limiting and fixing groove 401. In this embodiment, the limiting and fixing groove 401 reduces the shaking of the panel 300, improves the tightness between the panel 300 and the electrical base 400, and fixes the installation position of the panel 300 and the electrical base 400, realizing quick and accurate alignment of the panel 300 and the electrical base 400, and simplifying the assembly process.

[0041] like Figure 1 As shown, in one embodiment, the outer shell 100 is further provided with a plurality of decorative blocks 130, which are spaced apart on the outer surface of the outer shell 100. In this embodiment, the spaced arrangement of the plurality of decorative blocks 130 increases the visual three-dimensionality of the inverted protective cover structure 10, making it easier for operators to grip and thus improving the anti-slip performance.

[0042] This application also provides an atomizer, including the inverted protective cap structure 10 described in any of the above embodiments. In this embodiment, the protective cap 200 of the atomizer is assembled onto the outer shell 100, making the atomizer assembly simple and the structure compact.

[0043] Compared with the prior art, this disclosure has at least the following advantages:

[0044] The aforementioned snap-on protective cover structure 10 uses a guide slope 110 and an abutment slope 211 to provide initial positioning and clamping. The tight clamping of the abutment slope 211 and the guide slope 110 causes the outer shell 100 to be clamped between the snap-on part 221 and the abutment slope 211 of the protective cover 200, thereby ensuring a tight connection between the protective cover 200 and the outer shell 100. Installation can be completed simply by aligning the protective cover 200 with the mounting hole 102 and pressing it down. The assembly process is simple and improves assembly efficiency. The protective cover 200 is directly snapped onto the outer shell 100, saving space for the snap-on bracket, increasing the installation space of the panel 300, which is beneficial for increasing the screen ratio of the panel 300, and making the structure of the snap-on protective cover structure 10 more compact.

[0045] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
