Description

Technical Field

[0001] The present invention relates to the technical field of electronic scales, and particularly to an electronic scale with the function of measuring human body fat content. Background Art

[0002] An electronic scale converts the weight of an object into an electrical signal through a sensor. After amplification, filtering, and A / D conversion processing, it is processed by a CPU and finally displayed in digital form on a display screen. There are now electronic scales that can measure human body fat content. By measuring the body resistance, the fat content can be estimated. Such electronic scales can not only measure body weight but also provide various health data such as fat percentage, muscle mass, and moisture content.

[0003] For example, the patent with the publication number CN206618483U discloses a body fat measuring instrument and electronic scale for humans, which is used to solve the problems of single function and inability to perform data communication of existing electronic scales; it can realize the functions of a body fat measuring instrument and an electronic scale, and at the same time can record measurement data and perform data analysis and storage, having good competitiveness among similar products.

[0004] Another example is the patent with the publication number CN2472227Y, which discloses an electronic scale with the function of measuring human body fat content. It mainly consists of electrode plates placed on the upper surface of the scale pan and combined with the scale pan, a human body impedance measurement circuit, a weight sensor and its signal processing circuit, a microprocessor MCU system, a display, a keyboard, etc. It integrates the function of measuring human body fat content by measuring human body impedance with the function of measuring human body weight. By using the correlation between the voltage drop generated by the human body with an alternating current pulse and the human body fat content and combining the input human height and age, it calculates the human body fat content, and the measured human body weight and human body fat content are output by the display, which is applied to daily life so that the measured person can conveniently measure the human body fat content while measuring the weight.

[0005] For another example, the patent with the publication number CN203132677U discloses an outer shell structure of an electronic scale with fat measurement function, which includes an upper shell, a transparent plate and a lower shell. There is a cavity for installing a control circuit board between the upper shell and the lower shell. One or more first openings penetrating the transparent plate are provided on the transparent plate. The upper shell and the lower shell are connected by a connection structure passing through the first openings of the transparent plate. A window for placing a display is provided on the upper end surface of the upper shell for carrying an object, and the value displayed on the display can be clearly viewed directly through the window. Moreover, the transparent plate is clamped between the upper shell and the lower shell, and the transparent plate is firmly installed, avoiding the disadvantages of failure after long-term use or being affected by moisture, and having a longer service life. However, in order to improve the measurement accuracy, some existing electronic scales capable of measuring fat content use eight electrode plates to inductively detect the body fat content, with four electrode plates in contact with the feet and four electrode plates in contact with the hands. The electrode plates on the hands are arranged at the handle position. However, it is difficult to solve the problems of the storage of some existing handles and the storage of the cables dragged by the movement of the handles. The handles and cables are messy and distributed on the electronic scale, which not only affects the aesthetics but also easily causes cable damage. In addition, some existing electronic scales only have a measurement function. After the user measures the body weight and fat content, they need to use exercise or other fitness equipment to assist in reducing fat and controlling body weight, etc. The electronic scale cannot assist the user in fitness to control the fat content, and its functionality is limited.

[0006] In view of the above problems, there is an urgent need to innovate and design on the basis of the original electronic scale. Summary of the Invention

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Embodiment 1: Please refer to Figures 1-13 , the present invention provides the following technical solution: An electronic scale with the function of measuring the body fat content of a human body, including a housing 1 and an integrated circuit board 2 installed in the housing 1. A weighing panel 3 is installed on the upper end surface of the housing 1. An embedded groove 4 is opened on the weighing panel 3, and four groups of foot electrode plates 5 are fixedly installed on the embedded groove 4; a gasket 7 is fixedly installed on the housing 1, a magnetic suction chuck 8 is fixedly installed on the gasket 7, and a cable 9 is slidably connected through the side wall of the housing 1. A control display 10 is electrically connected to the cable 9. Two groups of hand electrode plates 12 are symmetrically fixed on both sides of the control display 10. A wire winding mechanism for autonomously storing the cable 9 is provided in the housing 1.

[0039] The wire winding mechanism includes a storage box 14 movably arranged in the housing 1. A turntable 15 is rotatably installed in the storage box 14, and the cable 9 is connected and wound around the outside of the turntable 15; a cylindrical rod 16 is coaxially fixed on the inner bottom surface of the storage box 14, and a scroll spring 17 is elastically connected between the cylindrical rod 16 and the inner side wall of the turntable 15.

[0040] The user places both feet on the weighing panel 3 according to the positions of the foot electrode plates 5 on the weighing panel 3, and quickly measures the user's weight. The user holds the outside of the handle 11, and the palm contacts the two hand electrode plates 12 on the handle 11. During detection, the foot electrode plates 5 and the hand electrode plates 12 send weak currents to the user. After the current passes through the human body, the electronic scale measures the conduction speed and resistance value of the current in different tissues. Since the resistance value of adipose tissue is relatively high, while the resistance value of muscle tissue is relatively low, the fat content can be calculated through these data. The four foot electrode plates 5 and the four hand electrode plates 12 can fully contact the user's body, and the detection of the fat content is relatively accurate.

[0041] When the user holds the outside of the handle 11, it is necessary to stretch the cable 9 outside the housing 1. When the cable 9 is stretched, it controls the turntable 15 to rotate in the storage box 14. The turntable 15 rotates to elastically stretch the scroll spring 17. When the electronic scale is not in use, place the control display 10 in the groove 6. The magnetic attraction card slot 13 at the bottom of the control display 10 is adsorbed and clamped outside the magnetic attraction card block 8, quickly restricting the storage positions of the control display 10 and the handle 11. At this time, the cable 9 connected beside the control display 10 is subjected to the pulling force of the rotation of the turntable 15. The turntable 15 rotates autonomously under the elastic pulling force of the scroll spring 17. The rotation of the turntable 15 causes the cable 9 to be wound around it, and the cable 9 moves back into the storage box 14 autonomously, achieving the purpose of automatically storing the cable 9, maintaining the aesthetics of the use of the electronic scale, and also protecting the cable 9.

[0042] Embodiment 2: On the basis of Embodiment 1, a vibration fat reduction mechanism is also disclosed, and its specific structure is as follows: A vibration fat reduction mechanism for helping the user control the fat content is provided in the housing 1; the vibration fat reduction mechanism includes a guide post 18 fixedly installed in the housing 1, a lifting post 19 is slidably connected in the guide post 18, and a foot pad 20 is fixedly installed on the lower end surface of the lifting post 19; a vibration spring 21 is elastically connected between the guide post 18 and the foot pad 20.

[0043] A slide rail 22 is fixedly installed in the housing 1, and a slide bar 23 is slidably connected in the slide rail 22. An upper moving seat 24 is fixedly installed on the upper end surface of the slide bar 23; a guide chute 25 is opened on the guide post 18, and an upper moving seat 26 is slidably connected in the guide chute 25. A push rod 27 is connected between the upper moving seat 26 and the lower moving seat 24.

[0044] The upper moving seat 26 is fixedly connected to the guide post 18. The upper moving seat 26 is rotatably connected to one end of the push rod 27, and the other end of the push rod 27 is rotatably connected to the lower moving seat 24.

[0045] Two limit card strips 28 are symmetrically fixed in the housing 1 about the central axis. A transverse moving seat 29 is slidably installed in the limit card strip 28, and the transverse moving seat 29 is fixedly connected to the storage box 14.

[0046] A moving frame 30 is fixedly installed on the outer side surface of the transverse moving seat 29. Two I-shaped seats 31 are slidably connected in the moving frame 30. A pull rope 32 is fixedly connected to the lower end surface of the I-shaped seat 31, and the other end of the pull rope 32 is fixedly connected to the slide bar 23; A plurality of guide disks 33 are fixedly installed on the inner bottom surface of the housing 1, and two guide disks 33 are clamped and limited outside the pull rope 32.

[0047] A micro motor 43 is fixedly installed on the upper end surface of the I-shaped seat 31. The output end of the micro motor 43 is connected to a rotating rod 44. The rotating rod 44 is rotatably installed on the I-shaped seat 31. Pressure rods 45 are symmetrically fixed on the rotating rod 44; The pressure rod 45 rotates and is in extrusion contact with the inner side wall of the moving frame 30.

[0048] The storage box 14 is provided with a switching mechanism for switching the pulling and pulling action of the cable 9. The switching mechanism includes a micro electric telescopic rod 34 fixedly mounted on the outside of the storage box 14, a lifting frame 35 fixedly connected to the output end of the micro electric telescopic rod 34, and a tooth block 36 fixedly connected to the lifting frame 35; tooth grooves 37 are provided on the storage box 14 and the turntable 15, and the positions of the tooth grooves 37 on the storage box 14 and the turntable 15 are correspondingly distributed up and down, and the tooth block 36 moves down and engages with the tooth grooves 37; positioning columns 38 are symmetrically fixed at both ends of the lifting frame 35, and a plurality of positioning holes 39 are evenly spaced on the limit card strip 28, and the positioning columns 38 move up and engage with the positioning holes 39; a circular arc piece 40 is fixedly mounted on the inner bottom surface of the shell 1, and the circular arc piece 40 is attached to the side of the I-shaped seat 31; a fixing seat 41 is fixedly mounted on the inner side wall of the shell 1, and a plurality of return springs 42 are elastically connected to the fixing seat 41 and the outer wall of the storage box 14.

[0049] The cable 9 stretching function can be switched according to the usage situation, and the micro electric telescopic rod 34 is operated to control the lifting frame 35 to move upward, and the lifting frame 35 drives the positioning column 38 to move upward synchronously, and the positioning column 38 moves and engages in the positioning hole 39 on the limit card strip 28. At this time, the storage box 14 is limited beside the limit card strip 28, and the lifting frame 35 moves upward to drive the tooth block 36 to move upward synchronously, and the tooth block 36 is separated from the tooth groove 37 on the turntable 15. The turntable 15 is in a loose state in the storage box 14. When the cable 9 is stretched, the turntable 15 can be driven to rotate in the storage box 14. When the cable 9 is loosened, the turntable 15 rotates to autonomously store the cable 9.

[0050] When the micro electric telescopic rod 34 is operated to control the lifting frame 35 to move downward, the lifting frame 35 drives the tooth block 36 to move downward and engage with the tooth groove 37. At this time, the turntable 15 is restricted in the storage box 14 and cannot rotate. The downward movement of the lifting frame 35 drives the positioning column 38 to separate from the positioning hole 39. The stretching cable 9 can control the directional movement of the storage box 14. The lateral movement seats 29 fixed on both sides of the storage box 14 are engaged in the limit card strips 28 and move. At the same time, the lateral movement seats 29 drive the moving frame 30 to move synchronously. The I-shaped seat 31 in the engaged state in the moving frame 30 also moves synchronously. When the I-shaped seat 31 moves, it can stretch the pull rope 32, so that the pull rope 32 moves along the transmission direction of the guide disk 33. The movement of the pull rope 32 controls the sliding strip 23 to engage and move in the slide rail 22. The sliding strip 23 drives the lower movement seat 24 to move synchronously. At this time, both ends of the push rod 27 connected between the lower movement seat 24 and the upper movement seat 26 rotate correspondingly. The rotation of the push rod 27 controls the upper movement seat 26 to engage and move in the guide chute 25. At this time, the guide column 18 is sleeved outside the lifting column 19 and moves longitudinally. By reciprocating the stretching cable 9, with the assistance of the vibration spring 21, the housing 1 can be controlled to vibrate reciprocally above the foot pad 20. Thus, when the user's hand reciprocally stretches the cable 9, the housing 1 generates vibration, which can exercise the hand muscles and achieve the purpose of fitness and fat reduction by vibrating the muscles, increasing the usage function of the electronic scale.

[0051] Operate the micro motor 43 to control the rotation of the rotating rod 44 and the pressure rod 45. The rotation of the pressure rod 45 squeezes against the inner side wall of the moving frame 30, so that the I-shaped seat 31 is engaged and fixed in the moving frame 30. Controlling the I-shaped seat 31 at the corresponding position to be engaged and fixed in the moving frame 30 can control the lifting movement between the guide column 18 and the lifting column 19 at the corresponding position, so that the vibration spring 21 at that place vibrates to control the housing 1 and regulate the amplitude of the up and down vibration of the housing 1.

[0052] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0053] Although the present invention 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 for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
