[0024] like Figures 1 to 5 As shown, this embodiment provides a waterproof structure for a coffee scale screen, including a weighing surface 1, a bottom cover 2, a weighing sensor 3, a control circuit board 4, and a display screen 5. The weighing surface 1 is fitted onto the bottom cover 2, and the weighing sensor 3 is fixed to the bottom cover 2. The weighing sensor 3 supports the weighing surface 1 to detect weight. The control circuit board 4 is disposed between the weighing surface 1 and the bottom cover 2. The control circuit board 4 is used to acquire the weighing data from the weighing sensor 3, analyze it, and send it to the display screen 5. The surface of the weighing surface 1 is provided with a groove 11, which extends from... One end of the weighing surface 1 extends to the other end of the weighing surface 1. The slot 11 is horizontally arranged, and a recessed step 111 is provided in the slot 11. The display screen 5 is set on the recessed step 111, and the surface of the display screen 5 is basically flush with the slot 11. A light-transmitting sheet 6 is fixed to the surface of the slot 11. The light-transmitting sheet 6 is fixed to the slot 11 with glue. By setting the display screen 5 on the recessed step 111 and covering the slot 11 with the light-transmitting sheet 6 and fixing it with glue, water can be prevented from flowing into the display screen 5 and damaging the circuit, thus improving the sealing performance.
[0025] As an optional embodiment, the light-transmitting sheet 6 is made of glass.
[0026] As an optional embodiment, the light-transmitting sheet 6 is fixed to the display screen 5 with glue so that the display screen 5 will not wobble within the step 111.
[0027] As an optional embodiment, the slot 11 is provided with a through hole 112 for electrical connection, and the display screen 5 extends a ribbon cable 51 to be electrically connected to the control circuit board 4.
[0028] As an optional embodiment, the display screen 5 is a TFT screen, which is a color screen with high speed, high brightness and high contrast.
[0029] As an optional embodiment, a battery 7 is provided inside the bottom cover 2. The battery 7 is electrically connected to the control circuit board 4 and is used to store electrical energy to power the entire coffee scale.
[0030] As an optional embodiment, the bottom cover 2 is provided with an electric switch 41 and a charging port 71. The charging port 71 is electrically connected to the battery 7 and is used to charge the battery 7. The electric switch 41 is electrically connected to the control circuit board 4 and is used to start or stop the entire coffee scale.
[0031] In existing coffee scales, water is easily splashed onto the surface during use, and this water can easily enter the display screen and damage the circuitry, rendering the entire coffee scale unusable. Therefore, a waterproof screen structure for coffee scales is provided. This structure involves creating a groove 11 on the surface of the scale surface 1, extending from one end to the other. A recessed step 111 is provided within the groove 11. The display screen 5 is mounted on the recessed step 111. A light-transmitting sheet 6 is fixed to the surface of the groove 11, and glue is applied between the light-transmitting sheet 6 and the groove 11 for fixation. By mounting the display screen 5 on the recessed step 111 and covering the groove 11 with the light-transmitting sheet 6, and fixing it with glue, water can be prevented from flowing into the display screen 5 and damaging the circuitry, thus improving the sealing performance.
[0032] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited thereto. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model are equivalent substitutions and are included within the protection scope of the present utility model.
