[0031] Please refer to Figure 1 , Figure 2 and Figure 3 , the present application first provides a knob structure, including shell 10, embedded support 20 and decorative sheet 30, embedded support 20 includes bottom plate 21, center column 22, first reinforcing rib 23 and at least two buckles 24, center column 22, first reinforcing rib 23 and buckle 24 are fixed to bottom plate 21, first reinforcing rib 23 is annular and surrounds center column 22, the top surface of first reinforcing rib 23 is flush with the top surface of center column 22; The shell 10 is annular and the inner wall is provided with a clamping groove 11, the embedded support 20 is located in the shell 10 and the buckle 24 is clamped with the clamping groove 11, the top of the shell 10 is also provided with an embedded groove 12, the bottom wall of the embedded groove 12 is higher than the top surface of the first reinforcing rib 23 and the center column 22, the decorative sheet 30 is attached to the bottom wall of the embedded groove 12 and is fixed with the top surface of the first reinforcing rib 23 and the center column 22 by adhesive.

[0032] In the application, the installation of the knob is completed by three sub-components of the shell 10, the embedded support 20 and the decorative sheet 30. The embedded support 20 is fixedly connected with the shell 10 through the buckle 24, and the decorative sheet 30 is fixedly connected with the center column 22 and the first reinforcing rib 23 of the embedded support 20, thereby reducing the number of sub-components and the installation difficulty and cost of the knob structure.

[0033] On this basis, the bottom wall of the embedded groove 12 is higher than the top surface of the first reinforcing rib 23 and the center column 22, that is, there is a gap between the bottom surface of the decorative sheet 30 and the top surface of the first reinforcing rib 23 and the center column 22, so that when the decorative sheet 30 is fixedly connected by glue, the excess glue can overflow along the gap, and the decorative sheet 30 can be flatly attached to the bottom wall of the embedded groove 12.

[0034] The existence of the annular first reinforcing rib 23 can improve the overall structural strength of the embedded support 20, and can increase the support area and the glue area of the embedded support 20 to the decorative sheet 30, improve the installation flatness and the adhesive reliability of the decorative sheet 30, and ensure that the decorative sheet 30 is firmly attached inside and outside, and prevent the edge of the decorative sheet 30 from being warped. The first reinforcing rib 23 and the embedded groove 12 are arranged in a radial direction and have a large interval, so that even if the glue track is deviated, the glue cannot overflow into the embedded groove 12, and the requirement for the glue equipment is lower, and the production is easier.

[0035] In addition, the shell 10 is made of aluminum alloy or other commonly used metal materials, and the embedded support 20 is made of plastic material, so as to reduce the amount of metal material as much as possible, and reduce the material cost of the knob structure of the application while ensuring that the appearance has a metal texture.

[0036] Specifically, the center column 22 is located at the center position of the bottom plate 21, so as to ensure the stable fixation of the decorative sheet 30.

[0037] More specifically, the decorative sheet 30 and the center column 22 are fixed by silicone glue.

[0038] Please refer to Figure 3 and Figure 4 In some embodiments, a first glue groove 22a is formed in the top surface of the center column 22, and a second glue groove 23a is formed in the top surface of the first reinforcing rib 23.

[0039] Due to the existence of the first glue groove 22a and the second glue groove 23a, during the gluing process, the glue will first fill the first glue groove 22a and the second glue groove 23a and then overflow outward, so as to ensure the glue area and the thickness of the glue layer, and improve the adhesive force of the gluing between the decorative sheet 30 and the center column.

[0040] In some embodiments, the second glue groove 23a has a width in the radial direction of greater than or equal to 3 mm, to ensure that the bonding strength of the first reinforcing rib 23 is sufficiently firm.

[0041] As shown in Figure 4 In some embodiments, the bottom plate 21 has a circular groove 21a formed on the bottom surface thereof corresponding to the first reinforcing rib 23; when the second glue groove 23a has a width in the radial direction of greater than or equal to 3 mm, the first reinforcing rib 23 has a greater width, which can cause the lower plane to shrink, thereby making the lower plane uneven, and the circular groove 21a formed on the bottom surface of the bottom plate 21 can effectively avoid the above situation.

[0042] As shown in Figure 2 and Figure 3 In some embodiments, the clamping groove 11 surrounds the inner wall of the shell 10 in the circumferential direction, and the inner wall of the shell 10 further has a guide portion 13 arranged in the circumferential direction, and the inner wall of the guide portion 13 includes a plurality of first guide surfaces 13a connected end to end in the circumferential direction of the shell 10.

[0043] The bottom plate 21 further has a guide column 25 fixed thereto, and the outer wall of the guide column 25 includes a plurality of second guide surfaces 25a connected in sequence in the circumferential direction of the shell 10, and the second guide surfaces 25a correspondingly abut part of the first guide surfaces 13a.

[0044] Through the first guide surfaces 13a arranged in the circumferential direction of the inner wall of the shell 10 and the second guide surfaces 25a of the outer wall of the guide column 25, the relative angle between the inner embedded bracket 20 and the shell 10 does not need to be considered during the process of inserting the inner embedded bracket 20 into the shell 10, and even if there is an angular deviation, the angle can be automatically adjusted during assembly due to the small design angle and small angular deviation of the single first guide surface 13a, so that the angle is matched in place, thereby effectively reducing the assembly difficulty, and the annular clamping groove 11 can ensure that the buckle 24 can be inserted into the clamping groove 11 and completed clamping regardless of the relative angle of the inner embedded bracket 20 and the shell 10 during insertion and installation, and the abutment between the first guide surface 13a and the second guide surface 25a can also serve as a rotational limiting function after assembly.

[0045] In some embodiments, each first guide surface 13a has a width in the circumferential direction of the shell 10 corresponding to a central angle of less than or equal to 10°, and each second guide surface 25a has a width in the circumferential direction of the shell 10 corresponding to a central angle identical to that of the first guide surface 13a.

[0046] It is not difficult to understand that the larger the central angle corresponding to the first guide surface 13a, the greater the possible angle deviation between the embedded support 20 and the shell 10 during assembly, and the weaker the ability of the two to automatically rotate and fine-tune the angle during assembly. By controlling the central angle corresponding to the first guide surface 13a to be 10° or less, it can be ensured that the embedded support 20 and the shell 10 can be assembled relatively smoothly.

[0047] Of course, if the central angle corresponding to the first guide surface 13a is too small, it will lead to greater processing difficulty and cost, and may affect the rotation limiting effect after assembly. Preferably, the central angle corresponding to the width of each first guide surface 13a in the circumferential direction of the shell 10 is 10°.

[0048] Please refer to Figure 2 and Figure 3 In some embodiments, a plurality of guide columns 25 and a plurality of buckles 24 are provided on the bottom plate 21, and the guide columns 25 and the buckles 24 are located outside the first reinforcing ribs 23 and are spaced apart and equally spaced apart in the circumferential direction of the shell 10.

[0049] The guide columns 25 equally spaced apart in the circumferential direction can ensure that the embedded support 20 is inserted into the shell 10 uniformly, thereby relatively rotating between the two relatively stably, and the buckles 24 equally spaced apart in the circumferential direction can ensure stable and reliable clamping.

[0050] Preferably, in some embodiments, four guide columns 25 and four buckles 24 are provided on the bottom plate 21.

[0051] Please refer to Figure 1 and Figure 2 In some embodiments, the clamping groove 11 is formed in the inner wall of the guide portion 13, and the height of the guide column 25 is greater than that of the buckle 24.

[0052] In this way, during the process of assembling the embedded support 20 into the shell 10, the guide column 25 will first contact the guide portion 13 and automatically rotate and fine-tune the angle therebetween, forming a sliding connection between the first guide surface 13a and the second guide surface 25a, and then the buckle 24 is clamped into the clamping groove 11. Through the sliding connection between the first guide surface 13a and the second guide surface 25a, the limiting between the embedded support 20 and the shell 10 in the circumferential direction is realized before clamping, thereby facilitating the clamping between the buckle 24 and the clamping groove 11, and achieving the effect of reducing the installation difficulty.

[0053] Please refer to Figure 2 and Figure 4As shown, in some embodiments, the guide portion 13 protrudes inwardly from the inner wall of the shell 10, and the top surface of the bottom plate 21 is flush with the bottom surface of the guide portion 13; through the mutual abutment of the top surface of the bottom plate 21 and the bottom surface of the guide portion 13, a limiting effect in the axial direction of the shell 10 can be achieved.

[0054] Specifically, the buckle 24 and the guide column 25 are both provided with a gap from the edge of the top surface of the bottom plate 21, so that the abutment surface of the top surface of the bottom plate 21 and the bottom surface of the guide portion 13 is annular, so as to ensure that the stress at each position is uniform when the embedded bracket 20 is installed in place, and the flatness is high.

[0055] More specifically, the bottom end of the inner wall of the shell 10 is formed with a chamfer, so as to facilitate the embedding of the embedded bracket 20 into the shell 10.

[0056] As shown in Figure 2 and Figure 3 As shown, in some embodiments, the bottom plate 21 is further fixed with a second reinforcing rib 26 corresponding to the guide column 25, the second reinforcing rib 26 penetrates the first reinforcing rib 23 in the radial direction, and one end is fixed with the center column 22 and the other end is fixed with the guide column 25; the second reinforcing rib 26 can further improve the structural strength of the embedded bracket 20.

[0057] Specifically, the second reinforcing rib 26 is fixed at the intermediate position of the inner wall of the guide column 25 in the circumferential direction.

[0058] More specifically, the top surface of the second reinforcing rib 26 located on the inner side of the first reinforcing rib 23 is flush with the top surface of the center column 22, and the top surface of the second reinforcing rib 26 located on the outer side is flush with the top surface of the guide column 25, and the top surface of the guide column 25 is lower than the bottom wall of the embedding groove 12; on the one hand, the second reinforcing rib 26 located on the inner side can guide the glue flow to another glue point when the glue liquid overflowed from the glue point of the first reinforcing rib 23 or the center column 22, on the other hand, it also makes the glue liquid unable to overflow into the embedding groove 12 through the second reinforcing rib 26 and the guide column 25, so as to ensure the installation flatness of the decorative sheet 30.

[0059] The second aspect of the present application provides a cooking equipment comprising the knob structure described above.

[0060] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present disclosure.

[0061] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several modifications and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
