Description

Technical Field

[0001] The utility model belongs to the technical field of body fat scales and relates to an LED guided body fat scale. Background Art

[0002] The measurement principle of the body fat scale is the BIA bioelectrical impedance measurement method, which generates a sinusoidal excitation signal through the electrode, and then detects the voltage signal from another electrode. The signal is amplified, rectified, A / D converted, and processed by the CPU to calculate the impedance of the human body. It is then combined with a human body composition analysis model that is deeply integrated and verified by massive samples to accurately measure multiple physical signs such as body fat rate and muscle rate.

[0003] The hand and foot electrodes generally used in body fat scales still have high requirements for contact with specific parts of the user's body, and are more dependent on the stability and consistency of the contact, otherwise it will affect the determination of the impedance value, thereby reducing the accuracy of body composition measurement and calculation. The user needs to stand in the correct area of ​​the scale surface and hold the handle correctly so that the hands and feet form good contact with the corresponding electrode sheets to complete data collection and calculation processing. The disadvantage of the body fat scale in the prior art is that during the actual use and operation of the user, there is a large degree of randomness in the contact position and state of the body parts and the corresponding electrodes, and the stability and consistency are difficult to guarantee in multiple measurements. The accumulation of these deviations will reduce the accuracy of the measurement. Utility Model Content

[0024] Reference Figure 1-4 As shown, an LED guided body fat scale includes a body fat scale body 100 and an LED light group 200. An electrode group 300 is provided on the surface of the body fat scale body 100. The electrode group 300 is used to contact the human body to form a loop to measure the impedance of the human body;

[0025] The surface of the body fat scale is provided with an LED light group 200, and the LED light group 200 is used to form a contour pattern to guide the human body to contact the electrode group 300.

[0026] The LED light group 200 forms a contour pattern on the surface of the body fat scale to guide the user's contact point with the body fat scale, thereby improving measurement accuracy and convenience. The contour pattern formed by the LED light group 200 can intuitively guide the user to the correct contact position on the body fat scale, ensuring good contact, thereby improving the accuracy of the measurement results. The visual guidance of the LED light group 200 enables the user to use the body fat scale correctly more easily without the need for complicated operating steps, thereby improving the convenience of using the body fat scale. The LED-guided body fat scale improves the user's correct use of the body fat scale through guidance, reduces errors in use, and improves user experience.

[0027] In this implementation case, a human body sensor 400 is also included. The human body sensor 400 is connected to the control module in the body fat scale body 100 to monitor the human body and trigger the LED light group 200.

[0028] In standby mode, the LED light group 200 is off, and when a human body is detected approaching, the LED lamp beads are controlled to enter a working state. A human body sensor 400 is added to realize a more intelligent function. The human body sensor 400 is connected to the control module in the body fat scale main body 100, and is used to monitor the human body to trigger the LED light group 200, so as to realize the intelligent control of the LED light group 200. The LED light group 200 is off in standby mode, and enters a working state only when a human body is detected approaching, which can reduce energy consumption, extend the service life of the LED light group 200, and has the advantages of energy saving and environmental protection. By detecting the approach of a human body through the human body sensor 400, the LED light group 200 can be automatically turned on and off, thereby improving the intelligence level of the body fat scale and making the user operation more convenient. The intelligent control of the LED light group 200 can enhance the user experience, making the body fat scale more intelligent and convenient, and meeting the needs and expectations of modern people for smart life.

[0029] In this implementation case, the human body sensor 400 is a microwave radar sensor.

[0030] The microwave radar sensor can emit microwave signals and receive echoes, and sense the surrounding environment and the movement of objects by detecting changes in echoes. In the LED guided body fat scale, the microwave radar sensor is used to monitor the approach of a human body. When a human body is detected approaching, the working state of the LED light group 200 is triggered, thereby realizing intelligent control.

[0031] The microwave radar sensor has high sensitivity and can accurately sense the approach of the human body, realize precise control of the LED light group 200, and improve the intelligence level of the body fat scale. Compared with infrared sensors, microwave radar sensors have stronger ability to penetrate obstacles and can better sense the approach of the human body. There is no need to directly aim at the sensor, which improves the convenience of use. Microwave radar sensors are less affected by environmental factors such as ambient light and temperature, have strong adaptability, and can stably and reliably monitor the approach of the human body.

[0032] In this embodiment, a handle 500 is also included, and the handle 500 is electrically connected to the body fat scale body 100, and an electrode area and an LED light group 200 are provided on the surface of the handle 500. By adding the electrode group 300, an eight-electrode body fat scale is formed, which can obtain human body impedance data more accurately, thereby improving the accuracy of the body fat scale measurement results. The eight-electrode body fat scale can provide more data dimensions, such as different parts of the limbs, and can more comprehensively analyze the body's fat rate, muscle rate and other data, providing users with a more detailed body composition analysis. Compared with the four-electrode body fat scale, the eight-electrode body fat scale is more stable during the measurement process and can reduce interference, thereby improving the stability and accuracy of the measurement.

[0033] The LED light group 200 on the handle 500 can help the user to accurately position the hand in the correct position to ensure good contact, thereby improving the accuracy of the measurement result. The design of the handle 500 makes it easier for the user to correctly hold and use the body fat scale, increases the convenience and stability of use, and thus improves the user experience.

[0034] In this implementation case, the handle 500 is connected to the body fat scale body 100 through a wire, the handle 500 is placed on the edge of the body fat scale body 100, and the human body sensor 400 is installed on the surface of the handle 500, and the human body sensor 400 is facing the top of the body fat scale body 100. The human body sensor 400 is installed on the surface of the handle 500 and faces the top of the body fat scale body 100. This design can more accurately sense the user's position and movement, thereby achieving more accurate user sensing and intelligent control. The design of placing the handle 500 on the edge makes it easier for the user to hold and operate during use, which improves the convenience of using the product. The human body sensor 400 is installed on the surface of the handle 500 and faces the top of the body fat scale body 100, which can more accurately sense the user's position and movement, thereby achieving more accurate user sensing and intelligent control, and improving the intelligence level of the product.

[0035] In this embodiment, the LED light group 200 uses RGB lamp beads. The body fat scale usually determines whether the contact between the human body and the electrode is good by detecting resistance and signal strength. When the human body is in good contact with the electrode, the resistance is low, the current can pass through the body smoothly, and the signal strength is also high; when the contact is not good, the resistance increases, the speed of the current passing through the body slows down, and the signal strength weakens. When the fat scale senses the approach of the user, the LED light group 200 enters a yellow low-frequency flashing state, indicating the area and outline of the electrode sheet, and guiding the user's hands to enter the correct holding posture. When the user's hands and feet are in the correct measurement state, the LED light group 200 enters a green steady-on state until the measurement process is completed, and the LED light group 200 turns off. The user puts back the handle 500 and leaves the body fat scale.
