Description

Technical Field

[0001] The invention relates to the technical field of body fat scales, and in particular to a split eight-electrode body fat scale and a connection structure thereof. Background Art

[0002] A body fat scale is a device specifically used to measure the body's fat content. The body fat scale measures the body's resistance through electric current transmission. The current enters the body from one electrode, passes through tissue and fat, and finally returns to another electrode. Based on the resistance of the body's tissue, the body fat scale can estimate the body's fat content.

[0003] The split body fat scale is mainly composed of three parts: a scale base, a handheld device and a connecting structure. The scale base is usually a platform, and the handheld device is an independent controller. The handheld device can be connected to the scale base through the connecting structure. Electrodes are set on both the scale base and the handheld device. The electrodes are divided into two parts, one part is located on the scale base and the other part is located on the handheld device. It can more accurately measure body fat content and other indicators. The electrodes of the handheld device can contact the upper body, while the electrodes of the scale base can contact the lower body, thereby providing more comprehensive body composition data.

[0004] Existing split body fat scales have many advantages, but the following problems may also occur during use:

[0005] Due to the different sizes and shapes of hands of different people, the electrodes in fixed positions may not be able to fit all hand shapes perfectly, thus affecting the transmission of current and the accuracy of measurement. If the electrodes cannot fully contact the hands, the current transmission may be disturbed or uneven, affecting the measurement results of fat content and other body indicators, resulting in inaccurate measurement results. At the same time, the electrodes of handheld devices are not adjustable. When using a body fat scale, users may need to take extra actions to ensure good contact between the hands and the electrodes, which may prevent users from finding a more comfortable measurement posture during measurement, increasing the discomfort during the measurement process.

[0006] Therefore, the present invention proposes a split eight-electrode body fat scale and its connection structure to make up for and improve the deficiencies of the prior art. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] refer to Figures 1 to 9According to a preferred embodiment of the present invention, a split eight-electrode body fat scale and its connection structure will be described in detail below. A split eight-electrode body fat scale and its connection structure include a scale base 1, a handheld device 2 for assisting the scale base 1 in measuring body fat is arranged on one side of the scale base 1, an adjustment structure 3 for adjusting the length of the handheld device 2 is arranged on the surface of the handheld device 2, and an adjustment structure 4 for adjusting the diameter of the handheld device 2 is arranged inside the handheld device 2;

[0042] The adjustment structure 13 includes a shell 31 slidably connected to the outer surface of the handheld device 2, the shell 31 is rotatably connected to a rotating shaft 32, the surface of the rotating shaft 32 is fixedly connected to a spring 133, the spring 133 is a vortex spring, it has a high degree of elasticity and plasticity, and can quickly restore its initial shape, the vortex spring is based on the interaction of each spiral ring of torsion and rotation, by converting external force into torsional energy, and using internal elastic restoring force to shrink or stretch, the spring 133 drives the connecting line 22 to shrink to the inside of the shell 31, so that the body fat scale as a whole is more compact, easy to carry and store in a limited space, and the end of the spring 133 away from the rotating shaft 32 is fixedly connected to a connecting ring 34;

[0043] A ratchet 35 is fixedly connected to the outer surface of the rotating shaft 32. The setting of the ratchet 35 allows the connecting line 22 to be pulled to the outside of the housing 31 and will not be retracted into the housing 31 during use. A control rod 36 is slidably connected to the inside of the housing 31. The control rod 36 extends to the outside of the housing 31. A spring 37 is fixedly connected to the inner wall of the housing 31. One end of the spring 37 away from the housing 31 is fixedly connected to the control rod 36. The control rod 36 is engaged with the ratchet 35.

[0044] The adjustment structure 2 4 includes an adjustment rod 41 rotatably connected to the inside of the handheld device 2, the adjustment rod 41 extends to the outside of the measuring rod 24, and a turntable 42 is fixedly connected to one end of the adjustment rod 41 close to the connecting rod 23, and an arc groove 43 is penetrated on one side of the turntable 42, and a small bump is arranged inside the arc groove 43 to increase the friction between the arc groove 43 and the slider 45, and the arc groove 43 is set to an arc shape, and the arc groove 43 is more difficult than the straight arc groove 43 to make the slider 45 drive the electrode 2 25 to reset through the connecting column 44, and the measuring rod 24 is slidably connected to the connecting column 44, and the surface of the connecting column 44 is fixedly connected to the slider 45, and the slider 45 is slidably connected to the inside of the arc groove 43, and the connecting column 44 extends to the outside of the measuring rod 24, and one end of the connecting column 44 extending to the outside of the measuring rod 24 is fixedly connected to a fixing plate 46, and the fixing plate 46 is fixedly connected to the electrode 2 25. By adjusting the distance between the fixing plate 46 and the center line of the measuring rod 24, the distance between the electrode 2 25 and the center line of the measuring rod 24 can be adjusted. By adjusting the electrode 2 25, the user's hand can fit more closely with the electrode 2 25, thereby reducing the measurement error, more accurately measuring the resistance value of the user's hand, and improving the accuracy of fat content measurement. It can better reflect the user's actual body fat situation and provide the user with a more valuable health management reference. The turntable 42 is fixedly connected to an auxiliary column 47 on the side away from the adjusting rod 41.

[0045] The scale base 1 includes a scale body 11, a display screen 12 is fixedly connected to the upper surface of the scale body 11, a magnetic attraction 13 is fixedly connected to one side of the scale body 11, an electrode 14 is fixedly connected to the upper surface of the scale body 11, four electrodes 14 are arranged, and the electrodes 14 are symmetrically distributed with respect to the center line of the scale body 11, a fixing groove 15 is provided at the bottom of the scale body 11, when the body fat scale is not in use, the adjustment structure 3 can be placed inside the fixing groove 15, so that the body fat scale is more compact and easy to carry, and the convenience of use is improved, and a connecting groove 16 is provided on the side of the scale body 11 away from the magnetic attraction 13.

[0046] The handheld device 2 includes a connector 21 that is rotatably connected to the inside of the connecting slot 16. The connector 21 is rotatably connected to the connecting slot 16. When in use, the user can more easily adjust the position and angle of the connecting line 22 when using the body fat scale to adapt to different body postures, providing the user with greater flexibility and comfort. At the same time, the rotational connection can reduce the tension and pulling force between the connecting line 22 and the body fat scale device, reduce the pressure on the connecting slot 16, and avoid the risk of bending, breaking and damage of the connecting line 22 due to the entanglement of the connecting line 22, thereby extending the service life of the device and making the user safer when using it.

[0047] A connecting line 22 is fixedly connected to the top of the connecting head 21. The connecting line 22 is arranged as an elastic line near the connecting head 21. The elastic line can provide a certain degree of softness and bendability, so that the user can be more flexible during use. The elastic line can also buffer and absorb external tension. When the user uses the body fat scale, the elastic line can absorb the tension caused by limb movement or improper posture, reducing the impact on the host and electrode plates, which helps to extend the service life of the product and reduce the risk of injury caused by accidental tension.

[0048] One end of the connecting wire 22 away from the connecting groove 16 is fixedly connected to a connecting rod 23, and both ends of the connecting rod 23 are rotatably connected to measuring rods 24. The user can rotate the measuring rod 24 to a comfortable holding position according to his or her own holding habits during measurement, thereby improving the user's holding comfort during measurement. The surface of the measuring rod 24 is slidably connected to electrode 2 25, and two electrodes 25 are provided, and are symmetrically arranged with respect to the center line of the connecting rod 23 as a reference. When measuring, the user can move electrode 2 25 left and right to a suitable holding position according to the size of his or her hand to adapt to people with different body shapes, thereby making the measurement process more comfortable and reducing discomfort. The surface of the connecting rod 23 is slidably connected to electrode 3 26, and two electrodes 3 26 are provided, and are symmetrically arranged with respect to the center line of the connecting rod 23 as a reference.

[0049] The surface of the connecting rod 23 is fixedly connected with a second magnet 27, the side of the magnet 13 away from the scale body 11 is the south pole (N pole), and the side of the magnet 27 away from the connecting rod 23 is the north pole (S pole). When the handheld device 2 is not in use, the handheld device 2 can be connected to the side of the scale body 11 fixedly connected with the magnet 13 through the surface of the connecting rod 23 with the second magnet 27. When the magnet 13 and the second magnet 27 are close to each other, an interaction of magnetic fields will occur between them. Since the directions of the magnetic fields of the two are opposite, that is, the south pole and the north pole are opposite, they will attract each other. Therefore, the handheld device 2 can be connected to the scale base 1. The magnetic attraction connection method can make the scale base 1 and the handheld device 2 quickly adsorbed together without complicated plugging and unplugging actions. The user only needs to bring the handheld device 2 close to the scale base 1 to achieve the connection, which saves cumbersome operating steps.

[0050] The housing 31 is slidably connected to the outer surface of the connecting line 22 .

[0051] The connecting ring 34 is fixedly connected to the connecting wire 22. An "L"-shaped hole is opened inside the connecting ring 34. Both ends of the connecting wire 22 extend from both ends of the "L"-shaped hole opened in the connecting ring 34 to the outside of the connecting ring 34, and both ends of the connecting wire 22 extend to the outside of the shell 31. The portion of the connecting wire 22 inside the shell 31 is distributed in a spiral shape. By adjusting the length of the connecting wire 22 extending to the outside of the shell 31, it is possible to adapt to the height differences between different users, meet the needs of different users, and improve the user's comfort and convenience.

[0052] The second adjustment structures 4 are symmetrically distributed with the center line of the connecting rod 23 as a reference, so that the user can use the second adjustment structures 4 to adjust the handheld device 2 according to usage habits.

[0053] The adjusting rod 41 is rotatably connected to the inside of the measuring rod 24 .

[0054] The following is the entire working process and working principle of the above embodiment:

[0055] Before use, the user rotates the handheld device 2 and the adjustment structure 3 270 degrees clockwise through the bottom of the scale base 1 with the center line of the scale base 1 as the axis, and moves the handheld device 2 and the adjustment structure 3 to the side close to the display screen 12.

[0056] When in use, first, the user pulls the connecting wire 22 out of the housing 31 according to his / her height and body shape. When pulling the connecting wire 22, the connecting wire 22 drives the spring 1 33 to contract through the fixedly connected connecting ring 34. When the spring 1 33 contracts, it drives the rotating shaft 32 fixedly connected thereto to rotate counterclockwise. When the user pulls the connecting wire 22 out to a suitable length, the spring 1 33 no longer contracts, and the spring 1 33 no longer drives the rotating shaft 32 to rotate counterclockwise. Since the ratchet 35 is fixedly connected to the surface of the rotating shaft 32, and the ratchet 35 is engaged with the control rod 36, when the user no longer pulls the connecting wire 22, the resilience of the spring 1 33 cannot drive the rotating shaft 32 to rotate clockwise.

[0057] Furthermore, when the user no longer measures, the user presses the control rod 36 in the direction close to the center line of the shell 31, and the control rod 36 moves in the direction close to the center line of the shell 31. When the control rod 36 moves in the direction close to the center line of the shell 31, the spring 2 37 is compressed. At this time, the control rod 36 is no longer engaged with the ratchet 35, and the resilience of the spring 1 33 can drive the rotating shaft 32 to rotate clockwise. When the rotating shaft 32 rotates clockwise, the rotating shaft 32 will retract the connecting line 22 fixedly connected by the connecting ring 34 into the shell 31 when it rotates clockwise. Through the above structure, different users can adjust the length of the handheld device 2 according to their own height and body shape to adapt to different usage needs, meet the needs of different users, and improve the user's comfort and convenience. At the same time, retracting the handheld device 2 to the inside of the adjustment structure 1 3 can reduce the size of the overall body fat scale, making the body fat scale more compact as a whole, and easy to carry and store in a limited space.

[0058] Next, the user can adjust the electrode 25 according to the size of his or her hand. When the user's hand is large, the user rotates the adjustment rod 41 clockwise. When the adjustment rod 41 rotates clockwise, the rotating disk 42 fixedly connected thereto is driven to rotate clockwise. When the rotating disk 42 rotates clockwise, the arc groove 43 provided on the surface of the rotating disk 42 pushes the slider 45 to move to a position away from the center line of the measuring rod 24. When the slider 45 moves to a position away from the center line of the measuring rod 24, the connecting column 44 fixedly connected to the slider 45 is driven to move to a position away from the center line of the measuring rod 24. The connecting column 44 When moving, the second electrode 25 fixedly connected by the fixing plate 46 is driven to move to a position away from the center line of the measuring rod 24. After the second electrode 25 moves to a position away from the center line of the measuring rod 24, the distance between the second electrode 25 and the center line of the measuring rod 24 becomes larger. At this time, the hand of a user with a larger hand fits more closely with the second electrode 25, and the grip is more comfortable. Since a small protrusion is provided inside the arc groove 43 to increase the friction between the arc groove 43 and the slider 45, the user will not squeeze the second electrode 25 to move to a position close to the center line of the measuring rod 24 when holding and measuring.

[0059] Furthermore, when the user has a smaller hand, the user rotates the adjustment rod 41 counterclockwise. When the adjustment rod 41 rotates counterclockwise, the turntable 42 fixedly connected thereto is driven to rotate counterclockwise. When the turntable 42 rotates counterclockwise, the arc groove 43 provided on the surface of the turntable 42 pushes the slider 45 to move toward a position close to the center line of the measuring rod 24. When the slider 45 moves toward a position close to the center line of the measuring rod 24, the connecting column 44 fixedly connected to the slider 45 is driven to move toward a position close to the center line of the measuring rod 24. When the connecting column 44 moves, it drives the electrode 2 25 fixedly connected thereto through the fixing plate 46 to move toward a position close to the center line of the measuring rod 24. After the electrode 25 moves toward a position close to the center line of the measuring rod 24, the distance between the electrode 25 and the center line of the measuring rod 24 becomes smaller. At this time, the hand of the user with a smaller hand fits the electrode 2 25 more closely, and the grip is more comfortable.

[0060] By adjusting the diameter of the electrode 25 through the above mechanism, the user can make the hand fit more closely with the electrode 25 according to the size of his or her hand, which can reduce the measurement error, more accurately measure the resistance value of the user's hand, improve the accuracy of fat content measurement, better reflect the user's actual body fat situation, and provide the user with a more valuable health management reference. The user can adjust the diameter of the electrode 25 on the surface of the measuring rod 24 according to his or her own grip, so that the user can find a more comfortable measurement posture and improve the comfort of the measurement process.

[0061] Finally, the user stands with both feet on the electrode 1 14 arranged on the upper surface of the scale body 11, and holds both hands on the surface of the electrode 2 25. The electrode 1 14 located on the top of the scale body 11 contacts the user's lower body, and the electrode 2 25 located on the surface of the measuring rod 24 and the electrode 3 26 located on the surface of the connecting rod 23 contact the user's upper body. The fat content of the user's upper and lower body is measured respectively, providing the user with more comprehensive body measurement data, so that the user can more accurately understand the fat distribution in different parts of the body.

[0062] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
