[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1: This utility model provides the following... Figure 1 - Figure 5 The RGB light indicator body fat scale shown includes a base shell 1 and a control chip 4. The control chip 4 is located inside the base shell 1. A tempered glass cover 2 is provided on the top of the base shell 1. The tempered glass cover 2 allows light to pass through so that the light-emitting body inside the base shell 1 can be seen. The control chip 4 is detachably installed inside the base shell 1 by screws. It also includes a support mechanism, with multiple sets of support mechanisms respectively set at the end corners of the bottom of the bottom shell 1. The support mechanism is used to support the bottom shell 1 off the ground. Specifically, the supporting institutions include: Support sleeve 3 is fitted onto the bottom of bottom shell 1. A buffer pad 302 is fixedly connected to the top of support sleeve 3. The top of buffer pad 302 fits against the bottom of bottom shell 1. Buffer pad 302 is made of foam and is connected to support sleeve 3 and bottom shell 1 by adhesive. The top support block 301 is slidably sleeved on the bottom of the support sleeve 3 and is inserted into the inside of the support sleeve 3. The bottom end of the support sleeve 3 has an opening, and the bottom of the top support block 301 is exposed through the opening at the bottom end of the support sleeve 3. The top diameter of the top support block 301 exceeds the opening. Therefore, the top support block 301 can slide through the opening under the constraint of the support sleeve 3 without detaching from the support sleeve 3. The maximum sliding distance of the top support block 301 is less than the distance exposed at the bottom end of the support sleeve 3.
[0027] Specifically, a battery pack 5 is provided at the bottom of the bottom shell 1. The output end of the battery pack 5 is electrically connected to the power supply end of the control chip 4. The battery pack 5 is used to provide power for the entire device.
[0028] Example 2: This utility model provides the following... Figure 9 The weighing unit shown is used in an RGB light-indicating body fat scale according to Embodiment 1. The weighing unit is located inside the bottom shell 1 and corresponds to multiple sets of support mechanisms. The transmitting end of the weighing unit is electrically connected to the receiving end of the control chip 4. The top support block 301 is used to transmit the top support force to the weighing unit. Specifically, the weighing unit includes: Protective shell 101 is fixedly connected to the inner wall of the end corner of the bottom shell 1; Pressure sensor 6, multiple pressure sensors 6 are respectively set in multiple protective shells 101. The measuring end of pressure sensor 6 is exposed at the bottom end of the bottom shell 1 and the supporting force is transmitted through the top support block 301. The output end of pressure sensor 6 is electrically connected to the receiving end of control chip 4.
[0029] It should be noted that the pressure sensor 6 is electrically connected to the control chip 4 via wiring. When the person being weighed steps on the top of the tempered glass cover 2, it will press down on the bottom shell 1. Under the support of the support mechanism, the bottom shell 1 is supported by the sliding support block 301, which applies pressure to the detection end of the pressure sensor 6. The pressure sensor 6 sends the detected pressure signal to the control chip 4. The control chip 4 calculates the weight of the person being weighed after signal processing, and records the valid weighing data for this weighing and compares it with the previous valid weighing record.
[0030] Example 3: This utility model provides the following... Figure 7 and Figure 8The body fat measurement unit shown is used in an RGB light-indicating electronic scale according to Embodiment 1. The body fat measurement unit is located at the corner of the bottom shell 1 and the tempered glass cover 2. The control terminal of the body fat measurement unit is electrically connected to the output terminal of the control chip 4. The body fat measurement unit is used to measure human body fat through bioelectrical impedance analysis. Specifically, the body fat measurement unit includes electrode pads 201, and multiple sets of electrode pads 201 are respectively disposed on the side of the top of the tempered glass cover plate 2. The power terminals of the electrode pads 201 are electrically connected to the control terminals of the control chip 4. It should be noted that this solution uses four sets of electrode pads 201. The electrode pads 201 are made of a conductive metal material (usually a bright silver or copper-colored area on the surface of the tempered glass cover 2). After the weigh-in person stands on the four sets of electrode pads 201, the control chip 4 generates a low-voltage alternating current of less than 500 microamps and 50 kHz. This alternating current is applied to the human body through the electrode pads 201. When the current flows through the body, it will encounter resistance. The control chip 4 measures the attenuated voltage signal through the electrodes on the feet and calculates the body's impedance value. The algorithm model in the control chip 4 will substitute the impedance and weight into the regression equation to estimate the body fat percentage.
[0031] An RGB light group 8 is installed inside the bottom shell 1 and below the electrode plate 201. The control chip 4 integrates a light-emitting control module 401. The output end of the light-emitting control module 401 is electrically connected to the receiving end of the RGB light group 8. The light-emitting control module 401 is used to control the RGB light group 8 to display different light colors.
[0032] It should be noted that the RGB light group 8 uses 5050RGB, an intelligent externally controlled LED light source integrating control and light-emitting circuits. Each LED light source is a pixel. Internally, the LED light source includes an intelligent digital interface data latching signal circuit, a power supply voltage regulator circuit, a built-in constant current circuit, a data regeneration circuit, and a high-precision RC oscillator. The output drive uses patented PWM technology, effectively ensuring the stability and color consistency of the LED light source. Data transmission uses a single-wire signal serial protocol, resulting in long transmission distances and strong anti-interference capabilities.
[0033] The RGB light group 8 is controlled by the control chip 4. When it receives a command, it compares the weight with the initial weight using the control chip 4. If the weight is lower than the initial weight, a green or blue light will illuminate; if the weight is higher than the initial weight, a red light will illuminate. The principle of the RGB light group 8's illumination control is as follows: The weight stability data G1 processed by the control chip 4 is compared with the previously stored weight stability data G0; When G1-G0≥0.5kg, a weight gain signal 01 is sent. After receiving the 01 signal, the RGB light group 8 lights up red. The weigher can know the weight by the color of the light penetrating the tempered glass cover 2. When G1 - G0 ≤ -0.5 kg, a weight loss signal 10 is sent. After the RGB lamp group 8 receives the 10 signal, it lights up green, and the person being weighed can know through the light color penetrating the tempered glass cover plate 2; When -0.5 kg < G1 - G0 < 0.5 kg, a maintenance signal 11 is sent. After the RGB lamp group 8 receives the 11 signal, it lights up blue, and the person being weighed can know through the light color penetrating the tempered glass cover plate 2.
[0034] Embodiment 4, the present utility model provides a display unit as Figure 6 shown, which is applied to a body fat electronic scale with RGB light indication in Embodiment 1. The display unit is arranged in the bottom case 1, and the receiving end of the display unit is electrically connected to the output end of the control chip 4. The display unit is used for displaying measurement results; Specifically, the display unit includes an LED display screen 7. The LED display screen 7 is arranged in the bottom case 1, and the receiving end of the LED display screen 7 is electrically connected to the output end of the control chip 4. After the LED display screen 7 receives the display signal sent by the control chip 4, it displays the weighing data.
[0035] The present utility model also provides a Bluetooth module as Figure 10 shown, which is applied to a body fat electronic scale with RGB light indication in Embodiment 1. The Bluetooth module can send the weight data and impedance signal processed by the control chip 4 to the APP. The APP combines the impedance, body weight, height, age and gender data, and substitutes them into the regression equation to estimate multiple indicators such as body fat percentage, muscle mass, bone mass and moisture percentage.
[0036] Finally, it should be noted that: the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
