Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a touch screen control panel for a coffee machine. Background Technology

[0002] With societal progress and rising living standards, touch-controlled products are gaining acceptance, and touch technology is increasingly being applied to home appliances. Current touch control technology is primarily used in touch control devices. The structure typically employs a rigid PCB material, on which touch spring buttons are soldered and light-emitting elements are positioned corresponding to the touch springs. When a touch spring button is touched, a capacitance is formed between the touch spring and the human body. Upon receiving this capacitance signal, the PCB board controls the electrical appliance to begin its corresponding operation. Furthermore, the light emitted by the light-emitting element corresponding to the touch spring button passes through the button and is displayed on the panel.

[0003] Conventional touch spring buttons have printed or sprayed patterned films for indication. However, if the patterned film is too large, the contact position of the human body with the patterned film may not correspond to the touch spring, resulting in the touch spring not sensing the signal or having reduced sensitivity. Utility Model Content

[0004] This invention overcomes the shortcomings of the prior art and provides a touch screen for a coffee machine control panel. By adding an ITO conductive film, it helps to enhance the sensitivity of the touch-sensitive spring to human contact with the panel.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A coffee machine control panel touch screen includes a panel bracket, a panel is disposed in front of the panel bracket, and a storage space is formed by the recess of the panel bracket facing the panel; an electronic control board is disposed in the storage space, and a touch-sensitive spring is disposed on the electronic control board; an ITO conductive film is disposed between the panel and the touch-sensitive spring; the touch-sensitive spring has a fixed end and a touch end, the fixed end is connected to the electronic control board, and the touch end is connected to the ITO conductive film.

[0007] Furthermore, it also includes a light shield, which has several clearances that correspond to the position and size of the touch-sensing spring. The touch-sensing spring is inserted through the clearances, and the clearances limit the movement of the touch-sensing spring.

[0008] Furthermore, the touch-sensitive spring is a square, one-piece molded shape.

[0009] Furthermore, the light-shielding plate is provided with a first mounting hole, and the panel bracket is provided with a second mounting hole corresponding to the first mounting hole.

[0010] Furthermore, the ITO conductive film and the touch-sensing spring are used in the same number and in a one-to-one correspondence.

[0011] Furthermore, the left and right sides of the panel form a curved surface that smoothly retracts towards the panel support.

[0012] Furthermore, the panel is a plastic panel or a glass panel.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This touchscreen incorporates an ITO conductive film between the panel and the touch-sensing spring, with the size of the ITO conductive film matching the size of the pattern film. This allows the structure formed by the combination of the ITO conductive film and the touch-sensing spring to have surface contact with the panel, resulting in a large contact area. Therefore, when a human touches the pattern film, it corresponds to the touch-sensing spring, leading to high sensitivity. Attached Figure Description

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0025] like Figures 1 to 2 As shown, this utility model discloses a touch screen control panel for a coffee machine, including a panel bracket 1 for fixing to the coffee machine. A panel 2 is disposed in front of the panel bracket 1. The panel 2 is a plastic sheet with a printed or sprayed pattern film on it. A storage space 3 is recessed on the side of the panel bracket 1 facing the panel 2. It can be understood that the panel 2 is installed on the panel bracket 1 to close the storage space 3.

[0026] An electronic control board 4 is installed in the storage space 3. A touch-sensitive spring 5 is installed on the electronic control board 4. An ITO conductive film 6 is installed between the panel 2 and the touch-sensitive spring 5. Specifically, the touch-sensitive spring 5 has a fixed end and a touch end. The fixed end is connected to the electronic control board 4. During operation, the touch-sensitive spring 5 receives a capacitive signal and transmits it to the electronic control board 4 to control the electrical appliance to start the corresponding operation.

[0027] Furthermore, panel 2 can be a plastic panel or a glass panel. Plastic panels are preferably IMD panels, which have good wear resistance and durability, as well as a glossy appearance and excellent performance.

[0028] In this application, the touch terminal is connected to the ITO conductive film 6. During design, the size of the ITO conductive film 6 is matched to the size of the patterned film, and the touch-sensitive spring 5 is a square, integrally molded shape. Figure 2 As you can see, the touch-sensitive spring 5 is a spiral-shaped linear structure. Therefore, in a traditional structure without the ITO conductive film 6, the touch-sensitive spring 5 is directly connected to the panel 2, forming a line contact with a small contact area. If the area of ​​the patterned film is large, the human body's contact position on the patterned film may not correspond to the touch-sensitive spring 5, causing the touch-sensitive spring 5 to fail to detect a signal or have reduced sensitivity. However, in this structure, by adding the ITO conductive film 6 between the panel 2 and the touch-sensitive spring 5, and ensuring that the area of ​​the ITO conductive film 6 matches the area of ​​the patterned film, the structure formed by the ITO conductive film 6 and the touch-sensitive spring 5 forms a surface contact with the panel 2, resulting in a large contact area. Therefore, the human body's contact on the patterned film always corresponds to the touch-sensitive spring 5, leading to high sensitivity.

[0029] Furthermore, the ITO conductive film 6 and the touch-sensitive spring 5 are used in the same number and in a one-to-one correspondence, which helps to correspond one-to-one with the pattern film on the panel 2, and they are independent of each other and do not interfere with each other.

[0030] It also includes a light shield 7, which is enclosed in the storage space 3. The light shield 7 has several clearance positions 8 that correspond to the positions and sizes of the touch sensing springs 5. The touch sensing springs 5 ​​are disposed through the clearance positions 8. The clearance positions 8 limit the touch sensing springs 5, making the touch sensing springs 5 ​​structurally stable, not easy to deviate, and highly stable.

[0031] The light-shielding plate 7 is provided with a first mounting hole 9, and the panel bracket 1 is provided with a second mounting hole 10 corresponding to the first mounting hole 9. The light-shielding plate 7 is fixed on the panel bracket 1 by screwing through the first mounting hole 9 and into the second mounting hole 10.

[0032] from Figure 1As can be seen, the left and right sides of panel 2 form a smooth arc surface that curves back towards panel support 1, resulting in a smooth structure, comfortable touch, and enhanced aesthetics.

[0033] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
