Technical Field

[0001] The present application relates to the technical field of small household appliances, and in particular to a touch button assembly and a heating base of a cooking utensil. Background Art

[0002] The existing cooking utensils that use touch button interaction usually use an IMD panel or PET surface sticker or directly laser engrave the operation interface on the appliance shell. The touch buttons are usually silk-screened on the IMD panel or PET surface sticker, or directly laser engraved on the appliance shell. Although the buttons silk-screened on the IMD panel or PET surface sticker can be made into a variety of colors, their surfaces cannot have any textures and lack touch feel; and the touch buttons laser engraved on the appliance shell can usually only be made into gray, black or white in color, and it is also difficult to make textures and lack touch feel. It can be seen that the touch buttons and the appliance shell in the prior art are an integral structure, and it is difficult to perform different process treatments on the touch buttons, so it is difficult for the touch buttons to provide a rich visual and tactile interactive experience at the same time.

[0012] In one embodiment, the shell is further provided with a plurality of strip holes extending radially outward along the assembly through hole, the strip holes are connected to the assembly through hole, a retaining rib is formed between any two adjacent strip holes, and the fixing portion at least partially abuts against one side of the retaining rib.

[0013] In this way, by setting the strip hole, the retaining rib can be deformed by the guide part squeezing the assembly through hole during installation, thereby expanding the area of ​​the assembly through hole, making it easier for the guide part and the fixing part to pass through the assembly through hole, thereby facilitating the installation of the touch button. After the installation is completed, the touch button can be firmly fixed by the fixing part abutting against the retaining rib.

[0014] In one of the embodiments, the touch button further includes an adhesive layer disposed on the back side of the touch portion, and the touch portion is bonded and fixed to the housing via the adhesive layer.

[0015] In this way, the provision of the adhesive layer improves the connection strength between the touch button and the housing, making the connection between the touch button and the housing more reliable.

[0016] In one embodiment, the adhesive layer is annular and surrounds the outer side of the buckle portion.

[0017] In this way, the annular adhesive layer can form a reliable seal to prevent water from entering the housing through the assembly through hole.

[0018] In one embodiment, the housing is provided with an assembly groove, the assembly through hole is provided on the bottom surface of the assembly groove, and the touch portion is at least partially received in the assembly groove.

[0019] In this way, the touch button is easy to install on the housing, and the touch button is firmly connected to the housing after installation.

The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.

[0037] See also Figures 1 to 3 The present application provides a touch button assembly, including a separately arranged shell 10 and a touch button 20. The touch button 20 includes a touch portion 21 and a buckle portion 22, the buckle portion 22 is connected to the back of the touch portion 21, and the buckle portion 22 is snap-connected to the assembly through hole 12 to install the touch button 20 on the shell 10. In this way, since the shell 10 and the touch button 20 are independent structures that are separately arranged, the touch button 20 can be processed separately, so that different surface treatment processes and colors can be applied to the surface of the touch portion 21 as needed, so that the touch button 20 can obtain a rich touch feel and color matching, thereby enriching the configuration and interactive experience of the interactive interface. The touch button 20 includes a touch portion 21 and a buckle portion 22, and has a simple structure, which is convenient for processing the touch portion 21 and convenient for installation.

[0038] In the present application, a pattern is provided on the front of the touch portion 21, and the pattern is protruding and / or recessed relative to the surface of the touch portion 21. In this way, the pattern on the touch portion 21 can provide a rich touch feel, thereby enhancing the user's touch experience. In one embodiment, the pattern on the front of the touch portion 21 is a CD pattern, but is not limited to this. The pattern on the front of the touch portion 21 can also be a grid pattern, a line pattern, or a pattern in other regular or irregular patterns, and the present application does not limit this. In addition, the touch portion 21 can also be provided with a color setting different from that of the housing 10 to obtain a rich visual effect.

[0039] For further information, see Figure 3 and Figure 4The buckle portion 22 includes a neck portion 221, a fixing portion 222 and a guide portion 223 connected in sequence. The neck portion 221 is connected to the touch portion 21. From the touch portion 21 to the buckle portion 22, the outer diameter of the fixing portion 222 gradually expands, and the outer diameter of the guide portion 223 gradually decreases. In this way, the guide portion 223 can easily extend into the assembly through hole 12, which is conducive to guiding the fixing portion 222 to pass through the assembly through hole 12, and the installation is very convenient. The fixing portion 222 can partially pass through the assembly through hole 12, and the other part can be pressed against the side of the housing 10 away from the touch portion 21, so that the touch button 20 is tightly buckled with the housing 10. It can be seen that the above-mentioned setting of the buckle portion 22 of this embodiment improves the installation efficiency of the touch button 20, and the touch button 20 is firmly connected to the housing 10 after installation.

[0040] Furthermore, the circumferential diameter of the connection between the neck 221 and the fixing portion 222 is smaller than the diameter of the assembly through hole 12, and the circumferential diameter of the connection between the fixing portion 222 and the guide portion 223 is larger than the diameter of the assembly through hole 12. In this way, the neck 221 will not be tightly attached to the inner wall of the assembly through hole 12, so that the neck 221 can easily penetrate into the assembly through hole 12 during installation, and the circumferential diameter of the connection between the fixing portion 222 and the guide portion 223 is larger than the diameter of the assembly through hole 12, so that the fixing portion 222 can clamp the touch button 20 to the housing 10.

[0041] Furthermore, the fixing portion 222 at least partially presses against a side of the housing 10 away from the touch portion 21 , thereby preventing the touch button 20 from being loosened relative to the housing 10 , and making the touch button 20 firmly mounted on the housing 10 .

[0042] For further information, see Figure 5 and Figure 6 The housing 10 is also provided with a plurality of strip holes 13 extending radially outward from the assembly through hole 12. The strip holes 13 are connected to the assembly through hole 12. A retaining rib 14 is formed between any two adjacent strip holes 13. The fixing portion 222 at least partially abuts against one side of the retaining rib 14. In this way, by providing the strip holes 13, the retaining rib 14 can be deformed by the guide portion 223 squeezing the assembly through hole 12 during installation, thereby expanding the area of ​​the assembly through hole 12, so that the guide portion 223 and the fixing portion 222 can more easily pass through the assembly through hole 12, facilitating the installation of the touch button 20. After installation, the fixing portion 222 abuts against the retaining rib 14 to firmly fix the touch button 20.

[0043] For further information, see Figure 3 and Figure 4 The touch button 20 further includes a back adhesive layer 23 disposed on the back of the touch portion 21, and the touch portion 21 is bonded and fixed to the housing 10 through the back adhesive layer 23. Thus, the provision of the back adhesive layer 23 improves the connection strength between the touch button 20 and the housing 10, making the connection between the touch button 20 and the housing 10 more reliable.

[0044] Furthermore, the adhesive layer 23 is annular and surrounds the outer side of the buckle portion 22 . Thus, the annular adhesive layer 23 can form a reliable seal to prevent water from entering the housing 10 through the assembly through hole 12 .

[0045] Furthermore, the housing 10 is provided with an assembly groove 11, the assembly through hole 12 is provided on the bottom surface of the assembly groove 11, and the touch portion 21 is at least partially received in the assembly groove 11. In this way, the touch button 20 is easily installed on the housing 10, and after installation, the touch button 20 is firmly connected to the housing 10, and the assembly groove 11 can shield the back and at least part of the side of the touch portion 21, so that the appearance of the touch button assembly is more beautiful.

[0046] See also Figure 1 , the touch button assembly also includes a circuit board assembly 30, which is arranged in the housing 10 and corresponds to the assembly groove 11. The circuit board assembly 30 includes a circuit board 31 and a touch elastic member 32, and the touch elastic member 32 is supported between the inner wall of the housing 10 and the circuit board 31. In this way, when the user touches the touch portion 21 of the touch button 20, the touch elastic member 32 can transmit the signal to the circuit board 31, and the circuit board 31 controls the opening or closing of the corresponding element according to the signal, thereby realizing the corresponding function. In this embodiment, the touch elastic member 32 is a compression spring with high sensitivity. It can be understood that it is an existing conventional technology for the human body to transmit the touch signal to the circuit board 31 through the touch elastic member 32 after touching the touch button 20, and its principle will not be repeated here.

[0047] Furthermore, the circuit board assembly 30 further includes a key frame 33 disposed on the circuit board 31, and the key frame 33 is provided with a limiting groove 331 corresponding to the assembly groove 11, and the touch elastic member 32 is disposed in the limiting groove 331. In this way, the limiting groove 331 can limit the installation position of the touch elastic member 32, prevent the touch elastic member 32 from being displaced, and thus prevent the touch elastic member 32 from being separated from the supporting effect on the housing 10 and the circuit board 31.

[0048] See also Figure 1 The present application also provides a heating base of a cooking utensil, including the touch button assembly as described above. The cooking utensil can be an electric steamer, an electric stew pot, an electric rice cooker, an electric frying pan, an electric kettle, etc., and the present application does not limit this.

[0049] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
