[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] like Figure 1-4 As shown, this utility model provides a touch structure, including a housing 1, a capacitive touch button diaphragm 2 and a touch panel 4. The capacitive touch button diaphragm 2 is fixed on the housing 1 and has instruction patterns printed on it. The touch panel 4 is fixedly covered on the top of the housing 1 and is located above the capacitive touch button diaphragm 2.

[0025] When applying a touch structure to stainless steel electrical products, a through hole is made in the stainless steel panel, and the touch structure is installed in the through hole position, with the touch panel 4 exposed. The instruction pattern is printed on the capacitive touch button membrane 2. The user can see the instruction pattern on the capacitive touch button membrane 2 through the touch panel 4 without affecting the visual effect. When using the touch structure, the touch position is the touch panel 4, and the user will not directly touch the instruction pattern, so there is no problem of wear and tear on the instruction pattern.

[0026] refer to Figure 3 The capacitive touch button diaphragm 2 is fixed to the top of the housing 1. The distance between the capacitive touch button diaphragm 2 and the touch panel 4 is minimized, and the capacitive touch button diaphragm 2 directly contacts the touch panel 4, ensuring that the user can clearly see the command pattern through the touch panel 4.

[0027] The touch control structure also includes a light control board 7, which is fixed inside the housing 1. The light control board 7 has several LED beads 8, and the housing 1 has several light-transmitting holes 10, the positions of which correspond one-to-one with the positions of the LED beads 8. The positions of the light-transmitting holes 10 should correspond one-to-one with the positions of the instruction patterns. When the user touches the touch panel 4 according to the position of the instruction pattern, the capacitive touch button diaphragm 2 receives the signal, controls the corresponding function to be implemented, and controls the corresponding LED beads 8 to light up.

[0028] The lighting control board 7 is fixed to the bottom of the housing 1. A light-blocking plate 9 is provided inside the housing 1, forming a light-transmitting hole 10 with the outer wall of the housing 1. The light-blocking plate 9 has a certain height and thickness, thus the light-transmitting hole 10 formed by the light-blocking plate 9 and the outer wall of the housing 1 has a certain depth. The light-blocking plate 9 can block the light emitted by the adjacent LED beads 8, ensuring that the light emitted by the LED beads 8 can only pass through the corresponding light-transmitting hole 10 directly above it and illuminate the corresponding instruction pattern directly above it, effectively avoiding mutual interference between the light sources. As a preferred embodiment, the light-blocking plate 9 can be made into a shape that is narrower at the top and wider at the bottom, with sloping sides. The wide bottom surface can block the light from adjacent surfaces, while the sloping sides allow the light to diffuse.

[0029] refer to Figure 4 The light-transmitting hole 10 includes a time indicator hole 1001 and several pattern indicator holes 1002. The time indicator hole 1001 is located in the middle of the housing 1, and the several pattern indicator holes 1002 are symmetrically arranged on both sides of the time indicator hole 1001.

[0030] A decorative film is fixed to the outer surface of the touch panel 4. When installing the touch structure, a through hole is made on the surface of the electrical appliance to be installed, and the touch panel 4 is installed at the through hole position. Since there is a difference between the color of the electrical appliance and the color of the touch panel 4, the touch panel 4 can be decorated with a decorative film to make the installation more aesthetically pleasing. The decorative film can be applied to the touch panel 4 using IMT technology or other methods.

[0031] refer to Figure 2 The touch panel 4 includes a touch portion 401 and a mounting portion 402 extending downward along the periphery of the touch panel. The mounting portion 402 has several locking holes 5, and the side wall of the housing 1 has several locking blocks 6, which are engaged in the locking holes 5. By engaging the locking holes 5 and the locking blocks 6, the touch panel 4 is fixed to the housing 1, making assembly simple.

[0032] The touch panel 4 has mounting posts 11 at both ends, and the housing 1 has mounting holes 12 at both ends that mate with the mounting posts 11. During assembly, the mounting posts 11 are first aligned with the mounting holes 12, and then the touch panel 4 is snapped onto the housing 1. The mounting posts 11 play a positioning role during the assembly process, making the snap-fit ​​more precise.

[0033] refer to Figure 3The housing 1 includes a main body 101 and a base plate 102. A capacitive touch button diaphragm 2 is fixed to the main body 101, and the base plate 102 is fixed to the bottom of the main body 101. Furthermore, a light control board 7 is fixed to the base plate 102, and the light control board 7 has several LED beads 8. Several light-transmitting holes 10 are opened inside the main body 101, and the positions of the light-transmitting holes 10 correspond one-to-one with the positions of the LED beads 8. By setting the base plate 102, the light control board 7 is first fixed to the base plate 102, and then the base plate 102 is fixed to the bottom of the main body 101, which facilitates the assembly of the light control board 7 and also facilitates the opening of the light-transmitting holes 10 inside the main body 101.

[0034] The base plate 102 is provided with several support columns 3. The lighting control board 7 is fixed on the support columns 3. The support columns 3 serve to support and fix the lighting control board 7. At the same time, the support columns 3 can also play a positioning role when fixing the lighting control board 7, ensuring that the assembly position of the lighting control board 7 is accurate.

[0035] This invention uses a capacitive touch button diaphragm 2 to print instruction patterns on the diaphragm 2. Users can see the instruction patterns on the capacitive touch button diaphragm 2 through the touch panel 4 without affecting the visual effect. When using the touch structure, the touch position is the touch panel 4, and the user will not touch the instruction patterns, so there is no problem of wear and tear on the instruction patterns.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model shall fall within the protection scope of the present utility model.
