[0027] Please refer to Figure 1 , Figure 2 and Figure 3 , the present application first provides a knob structure, including shell 10, embedded bracket 20 and decorative sheet 30, embedded bracket 20 includes bottom plate 21, center column 22 and at least two buckles 23, center column 22 and buckle 23 are fixed to bottom plate 21, shell 10 is annular and the inner wall is provided with clamping groove 11, bottom plate 21 is located in shell 10 and buckle 23 is clamped with clamping groove 11, to limit the relative displacement between embedded bracket 20 and shell 10 along the axial direction of shell 10, decorative sheet 30 is fixed on the top of center column 22 and is attached with shell 10.
[0028] In the present application, the installation of the knob is completed by three sub-components of shell 10, embedded bracket 20 and decorative sheet 30, wherein the embedded bracket 20 is assembled into the shell 10 through the buckle 23, and the decorative sheet 30 is fixed with the center column 22 of the embedded bracket 20, which reduces the number of sub-components and reduces the installation difficulty and cost of the knob structure.
[0029] In addition, the shell 10 is made of aluminum alloy or other commonly used metal materials, and the embedded bracket 20 is made of plastic material, so as to reduce the amount of metal material as much as possible, while ensuring that the appearance has a metal texture, and as much as possible to reduce the material cost of the knob structure of the present application.
[0030] Specifically, the center column 22 is located at the center position of the bottom plate 21 to ensure that the decorative sheet 30 is fixed stably, and each buckle 23 is uniformly arranged on the bottom plate 21 along the circumferential direction of the shell 10 to ensure that the clamping and fixing is stable and reliable.
[0031] More specifically, the bottom plate 21 is uniformly provided with four buckles 23 along the circumferential direction of the shell 10.
[0032] Please refer to Figure 2 , Figure 3 and Figure 4 , in some embodiments, the clamping groove 11 surrounds the inner wall of the shell 10 in the circumferential direction; the inner wall of the shell 10 on the upper side of the clamping groove 11 is the upper ring wall 12, and the inner wall on the lower side of the clamping groove 11 is the lower ring wall 13. The diameter of the upper ring wall 12 is smaller than that of the lower ring wall 13, that is, the upper ring wall 12 protrudes inwardly from the lower ring wall 13.
[0033] The protruding part of the upper ring wall 12 relative to the lower ring wall 13 can limit and block the buckle 23 to some extent, so as to avoid the situation that the buckle 23 is separated from the clamping groove 11 due to excessive force during installation.
[0034] Please refer to Figure 2 and Figure 3 , in some embodiments, the upper ring wall 12 is fixed with a limiting block 12a, the bottom surface of the limiting block 12a is flush with the lower edge of the upper ring wall 12, and the bottom plate 21 is fixed with a limiting column 24, the top surface of the limiting column 24 is in contact with the bottom surface of the limiting block 12a; through the mutual top of the limiting column 24 and the limiting block 12a, a limiting effect in the axial direction of the shell 10 can be achieved.
[0035] Specifically, the upper ring wall 12 is uniformly provided with a plurality of limiting blocks 12a along the circumferential direction, and the bottom plate 21 is uniformly provided with a plurality of limiting columns 24 corresponding to the limiting blocks 12a along the circumferential direction, so as to ensure that the forces at various positions are uniform when the embedded bracket 20 is installed in place, and the flatness is high.
[0036] Please refer to Figure 2 and Figure 3 , in some embodiments, the bottom plate 21 is further fixed with a reinforcing rib 25, one end of the reinforcing rib 25 is fixed with the limiting column 24, and the other end is fixed with the center column 22, so as to improve the structural strength of the embedded bracket 20.
[0037] Please refer to Figure 2 and Figure 3 , in some embodiments, the upper ring wall 12 is fixed with a guide block 12b, and the bottom plate 21 is fixed with a guide column 26. The guide block 12b is in contact with the guide column 26 along the circumferential direction of the shell 10, and is in sliding connection with the guide column 26 along the axial direction of the shell 10; through the sliding fit between the guide block 12b and the guide column 26, a rotary limiting effect can be achieved, so as to prevent relative rotation between the embedded bracket 20 and the shell 10.
[0038] Specifically, the upper ring wall 12 is uniformly provided with a plurality of guide blocks 12b in the circumferential direction, and the bottom plate 21 is uniformly provided with a plurality of guide columns 26 corresponding to the limiting blocks 12a in the circumferential direction.
[0039] More specifically, the guide column 26 is in a U-shaped cross section in the horizontal direction, and the guide block 12b is embedded in the U-shaped groove of the guide column 26.
[0040] In some embodiments, the top of the guide column 26 is higher than the top of the buckle 23, and the distance between the two in the axial direction of the shell 10 is greater than the distance between the guide block 12b and the bottom wall of the clamping groove 11 in the axial direction of the shell 10.
[0041] In this way, during the process of installing the embedded bracket 20 into the shell 10, the guide column 26 will first contact the guide block 12b and form a sliding connection, and then the buckle 23 will be clamped into the clamping groove 11; through the sliding connection between the guide column 26 and the guide block 12b, the limiting between the embedded bracket 20 and the shell 10 in the circumferential direction is realized before clamping, thereby facilitating the clamping between the buckle 23 and the clamping groove 11, and achieving the effect of reducing the installation difficulty.
[0042] Please refer to Figure 2 and Figure 3 It is shown that in some embodiments, the bottom of the lower ring wall 13 is chamfered to facilitate the installation of the embedded bracket 20 into the shell 10.
[0043] Preferably, the top of the buckle 23 is also chamfered on the outer side to facilitate the installation of the embedded bracket 20 into the shell 10 and the clamping of the buckle 23 into the clamping groove 11.
[0044] Please refer to Figure 2 and Figure 4 It is shown that in some embodiments, the top of the shell 10 is provided with an embedding groove 14, and there is a distance between the bottom wall of the embedding groove 14 and the top surface of the center column 22. The top surface of the center column 22 is provided with a glue containing groove 22a, and the decorative sheet 30 is attached to the bottom wall of the embedding groove 14 and is glued and fixed to the top surface of the center column 22.
[0045] Due to the existence of the glue containing groove 22a, the glue will overflow outward after filling the glue containing groove 22a to ensure the glue area and the thickness of the glue layer, thereby improving the adhesion between the decorative sheet 30 and the center column. The distance between the bottom wall of the embedding groove 14 and the top surface of the center column 22 allows the excess glue to overflow through the gap between the decorative sheet 30 and the top surface of the center column 22, ensuring that the decorative sheet 30 can be flatly attached to the bottom wall of the embedding groove 14.
[0046] Specifically, the decorative sheet 30 and the center column 22 are fixed by silicone glue.
[0047] Please refer to Figure 4As shown, in some embodiments, the top surface of each limiting block 12a and each guiding block 12b is flush with the bottom wall of the embedding groove 14, so as to increase the supporting area of the decorative sheet 30 and improve the installation flatness of the decorative sheet 30.
[0048] Of course, in other embodiments, the decorative sheet 30 can also be fixed to the shell 10 or the embedded bracket 20 by clamping, threaded connection, interference fit or other common fixing methods, which are not limited herein.
[0049] The second aspect of the present application provides a cooking device comprising the knob structure described above.
[0050] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not contradict, they should be considered as falling within the scope of the present application.
[0051] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be pointed out that, for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
