DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings.

[0022] The buckle-type coil disk quick-installation structure of the utility model is as follows: Figures 1 to 3 As shown, the induction cooker comprises a bottom shell 1 and a coil frame 3. The bottom shell 1 is in a basin shape, and the coil frame 3 is in a flat plate shape. The bottom shell 1 is formed with an inner bottom 101, which is the inner wall of the bottom of the bottom shell 1. The coil frame 3 is arranged above the inner bottom 101. The induction cooker is also provided with a glass panel, and the glass panel cover is arranged on the bottom shell 1. Figure 6 and Figure 7 As shown, the outer periphery of the coil frame 3 is formed with buckle holes 311 distributed circumferentially, and the number of buckle holes 311 is two or more. Figure 6 The example shows that the number of buckle holes 311 is four. Figure 3 As shown, a bracket 2 is provided on the bottom shell 1. Figure 5 As shown, the bracket 2 is formed with an elastic plate portion 210, and the upper end of the elastic plate portion 210 is formed with a buckle hook 21, as shown in FIG. Figure 2 As shown, the elastic plate portion 210 is disposed through the corresponding buckle hole 311, and the buckle hook 21 is buckled on the upper side of the edge of the corresponding buckle hole 311, as shown in FIG. Figure 4 As shown, the elastic plate portion 210 is radially attached to the inner wall of one side of the corresponding buckle hole 311. The "radial direction" mentioned here refers to the central axis of the coil disc frame 3, and can also be understood as the radial direction of the coil on the coil disc frame 3. The width of the buckle hole 311 in the radial direction is greater than the thickness of the elastic plate portion 210, so that the buckle hook 21 can pass through the buckle hole 311; Figure 2 As shown, the elastic plate portion 210 is adapted to be connected with the corresponding buckle hole 311 in the circumferential direction, where the “circumferential direction” mentioned here refers to the central axis of the coil bobbin 3 .

[0023] The coil is first wound on the top of the coil drum frame 3. During the assembly process, each snap-in hole 311 is aligned with the corresponding elastic plate portion 210, and then the coil drum frame 3 is pressed downward. In this process, because the lower edge of the snap-in hole 311 relatively pushes the elastic plate portion 210, the elastic plate portion 210 is elastically bent and deformed slightly, so that each snap hook 21 can slide into the corresponding snap-in hole 311 at the same time, and then the snap hook 21 passes through the snap-in hole 311 relatively upward, and the elastic plate portion 210 is also inserted into the corresponding snap-in hole 311. When the snap hook 21 passes over the snap-in hole 311, the elastic plate portion 210 elastically resets and swings, so that the snap hook 21 moves radially and snaps on the upper side of the edge of the corresponding snap-in hole 311, which is beneficial to the positioning of the coil drum frame 3 and avoids the coil drum frame 3 The bracket 2 is separated upward from the bracket 2, and since the elastic plate portion 210 is radially abutted against the inner wall of one side of the corresponding snap-on hole 311 and the snap-on holes 311 are circumferentially distributed, the bracket 2 plays a radial positioning role for the coil disc frame 3 to prevent the coil disc frame 3 from shifting horizontally, and since the elastic plate portion 210 is circumferentially adapted and connected with the corresponding snap-on holes 311, the circumferential shift of the coil disc frame 3 is prevented, that is, the circumferential inner wall of the snap-on hole 311 is abutted against and blocks the elastic plate portion 210, so that the coil disc frame 3 is installed sufficiently firmly; as can be seen from the above, since the installation of the coil disc frame 3 only requires a simple downward movement, it is beneficial to quickly install the coil disc frame 3, and it is beneficial to enable the installation of the coil disc frame 3 and the bottom shell 1 to be achieved through automated equipment. When the coil disc frame 3 needs to be disassembled, the elastic plate portion 210 is elastically bent and deformed to move the hook 21 to a position aligned with the snap-on hole 311. At this time, the coil disc frame 3 is pulled upward to allow the hook 21 to pass relatively downward through the snap-on hole 311, thereby quickly separating the coil disc frame 3 from the bottom shell 1, making it easy to disassemble the coil disc frame 3.

[0024] Furthermore, if Figure 6 and Figure 7 As shown, the outer periphery of the coil bobbin 3 is formed with a lug portion 31, and the snap-fitting hole 311 is formed on the corresponding lug portion 31, so that the outer diameter setting of the coil bobbin 3 body can be reduced, which is beneficial to saving materials used to make the coil bobbin 3 and reducing costs.

[0025] Furthermore, if Figure 5 As shown, the bracket 2 is formed with a support plate 20, the lower end of the support plate 20 is connected to the inner bottom 101 as a whole, so as to avoid the bracket 2 needing to be installed and connected to the bottom shell 1 separately, and the upper end of the support plate 20 is formed with a support plate top surface 201, and the support plate top surface 201 is parallel to the horizontal plane, such as Figure 2As shown, the lug 31 is attached to the corresponding support plate top surface 201, and then the buckle hook 21 is buckled on the upper side of the edge of the corresponding buckle hole 311, so that the coil frame 3 cannot be shifted in the up and down directions. Therefore, the bracket 2 positions the coil frame 3 in each direction, avoiding the need to set up an additional structure for supporting the coil frame 3, which is conducive to simplifying the installation structure of the bottom shell 1 and the coil frame 3. Figure 3 and Figure 5 As shown, the elastic plate portion 210 is connected to the support plate 20 as a whole, which is beneficial to simplifying the assembly structure and improving the position accuracy of the hook 21 so that the coil disc frame 3 and the bottom shell 1 are easy to assemble accurately.

[0026] Furthermore, if Figure 6 As shown, the coil bobbin 3 is formed with an outer cylindrical surface 301, and the lug portion 31 is specifically formed on the outer cylindrical surface 301, and the central axis of the outer cylindrical surface 301 is along the up-down direction, as shown in FIG. Figure 3 and Figure 5 As shown, the support plate 20 is configured to be in an arc shape, such as Figure 2 As shown, the support plate 20 is adapted to be attached to the outer cylindrical surface 301 , that is, the arc shape of the support plate 20 is concentric with the outer cylindrical surface 301 , so that the support plate 20 further radially positions the coil bobbin 3 with high strength.

[0027] Furthermore, if Figure 2 and Figure 4 As shown, the elastic plate portion 210 is pressed outwardly against the inner wall of the corresponding snap-on hole 311. Specifically, the inner wall of the snap-on hole 311 at one end relatively far from the central axis of the coil disc frame 3 is pressed against the elastic plate portion 210, so that the buckle 21 is in an outward hook shape, and the elastic plate portion 210 can be elastically bent and deformed radially inward. That is to say, when the coil disc frame 3 needs to be disassembled, the buckle 21 is pushed toward the central axis of the coil disc frame 3 to elastically bend and deform the elastic plate portion 210. At this time, the coil disc frame 3 is pulled upward, so that the buckle 21 can pass through the snap-on hole 311 relatively downward, so that the coil disc frame 3 can be quickly separated from the bottom shell 1. Figure 6 As shown, an escape notch 202 for evading the elastic plate portion 210 is formed at the upper end of the support plate 20. Therefore, when the thickness dimension of the lug portion 31 in the up and down directions remains unchanged, it is beneficial to increase the length setting of the elastic plate portion 210 in the up and down directions, so as to avoid the support plate 20 hindering the elastic plate portion 210 from swinging radially inward, thereby making the elastic plate portion 210 have good elastic swinging performance, making the coil disc frame 3 easy to install, and also avoiding the connection between the elastic plate portion 210 and the support plate 20 from being easily broken.

[0028] Furthermore, if Figures 6 to 8 As shown, a peripheral edge 312 is formed on the lower side of the lug portion 31 , and the buckle hole 311 is disposed on the inner side of the peripheral edge 312 , so that the peripheral edge 312 can increase the structural strength of the lug portion 31 .

[0029] like Figure 8 As shown, the inner wall of one end of the buckle hole 311 which is relatively far away from the central axis of the coil disc frame 3 is set as a guiding slope 3111, so that the buckle hole 311 is small at the top and large at the bottom, so that the guiding slope 3111 can contact and guide the buckle hook 21 to slide relatively upward into the buckle hole 311.
