Description

A body fat scale with the function of measuring user's body data

Technical Field

The present invention relates to the technical field of body fat scales, and in particular to a body fat scale capable of measuring user's body data.

Background Art

A body fat scale is an electronic scale that can measure the body's fat content. Its principle is to use bioimpedance technology and pressure sensor technology to measure and calculate the body's fat content and body weight. Bioimpedance technology uses the difference in conductivity of human tissue to calculate the body's composition through the resistance value when current passes through the human body. Pressure sensor technology can convert body weight into electrical signals, which are processed and displayed through electronic circuits. Finally, the measured data is processed and analyzed to obtain various data indicators of body composition.

At present, in order to ensure that the calculated parameters such as body fat are more accurate, body fat scales usually use eight electrodes for data collection and measurement. The eight electrodes include four electrodes distributed on the handle and four electrodes distributed on the scale body, which measure the impedance of the upper and lower limbs of the human body respectively. However, in the existing eight-electrode body fat scales, the positions of the four electrodes for measuring the impedance of the lower limbs are fixed and cannot be adjusted according to needs. Since the size of each person's feet is different, especially the difference between the feet of children and adults is very large, the lower limb electrodes that cannot adjust the measurement interval are difficult to meet the use needs of different groups of people at the same time. When the positions of the four electrodes on the body fat scale are greatly different from the actual needs, the soles of the feet cannot fit well with the four electrodes, which will have a great impact on the measurement of body fat, resulting in a large deviation in the measurement data, making the body fat scale unable to accurately realize the measurement and calculation of the user's body data. Therefore, it is necessary to provide a body fat scale with the function of measuring user's body data to solve the above problems.

Furthermore, two through slots are provided on the adjacent sides of the two storage boxes 601, and a through hole adapted to the connection line three 13 is provided on the side of the storage box 601 located between the two through slots.

The handle 9 can be conveniently buckled out of the storage box 601 through the two through slots, and the connecting wire three 13 can pass through and be connected to the handle 9 through the through hole.

In combination with the above preferred embodiments, the working principle of the present invention is as follows:

The steps of use are as follows: first, the user places the body fat scale body 1 horizontally on the ground, then inserts both hands into the groove 1 602 respectively, and pulls the storage box 601 outward. Since the outer side of the storage box 601 is fixedly connected to two limit blocks 603 slidably connected to the connecting seat 2, the storage box 601 will be supported and limited by the limit blocks 603 during the movement, so that the storage box 601 can slide stably within the fixed stroke. When the storage box 601 moves to the maximum movement stroke, the handle 9 will be exposed from the connecting seat 2. At this time, the user can take out the two handles 9 from the two storage boxes 601 respectively through the through slots on the storage box 601 and hold them. When holding the handles 9 separately, the two handles 9 can be pulled in opposite directions, so that the handles 9 drive the connecting wire 3 13 to extend out from the connecting seat 2. Since the connecting wire 3 13 is wound around the outside of the storage shaft 807, and one end of the connecting wire 3 13 passes through and is fixed in the storage shaft 807, the stretching of the connecting wire 3 13 can drive the storage shaft 807 to rotate in the body 1 of the body fat scale. The rotating storage shaft 807 can drive one end of the torsion spring 1202 in the support sleeve 1201 to rotate, so that the spiral wire in the spiral shape of the torsion spring 1202 generates a torsional torque, which causes the spiral wire to rotate around the spiral shaft, thereby causing the spiral shape of the torsion spring 1202 to change, and realizing the storage of torsional energy.

When the two handles 9 are stretched to a suitable length, the user places his feet on the top of the two support plates 501, stands up straight, and continues to pull the handle 9 to adjust the position of the upper and lower limb electrodes 4 of the movable disk 3. In the process of the handle 9 pulling the connecting line three 13, the connecting line three 13 can continue to drive the storage shaft 807 to rotate, and the rotating storage shaft 807 can drive the fixing sleeve 1001 and the limiting sleeve 1101 to rotate. Since the conductive disk 1002 is connected to the connecting line three 13, and the conductive disk 1002 is always in close contact with the conductive seat 1003, the measurement signal on the handle 9 will be transmitted to the conductive disk 1002 through the connecting line three 13, and then through The conductive seat 1003 and the second connecting line 1004 act on the body 1 of the body fat scale for analysis and calculation. Since the conductive disk 1002 is rotatably installed on the inner side of the limiting sleeve 1101, the ratchet 1102 driven by the storage shaft 807 can push the conductive seat 1003 to move toward the horizontal center line of the connecting seat 2. The movement of the claw 1103 drives the movable seat 1104 to move, and the movable seat 1104 compresses the spring 1105. When the storage shaft 807 no longer rotates, the claw 1103 is clamped at one end of the ratchet 1102 under the action of the restoring elasticity of the spring 1105, thereby controlling the unidirectional rotation of the storage shaft 807.

The rotating storage shaft 807 can also drive the two bevel gears 806 on its outer side to rotate, and the rotating bevel gear 806 drives the bevel gear 1 805 meshing with it to rotate. After the rotating bevel gear 1 805 can drive the transmission shaft 804 to rotate, the rotating transmission shaft 804 drives the two worm gears 803 connected on its outer side to rotate synchronously. Since the outer threads of the two worm gears 803 on the transmission shaft 804 have opposite rotation directions, the rotating two worm gears 803 can drive the two worm wheels 802 to rotate synchronously in opposite directions. The rotating worm wheel 802 can drive the connecting shaft 801 to rotate. Since the top end of the connecting shaft 801 passes through the connecting seat 2 and the fixed disk 701 and is fixedly connected to the movable disk 3, the rotation of the two connecting shafts 801 can drive the two movable disks 3 to rotate in opposite directions. The two movable disks 3 rotating in opposite directions can drive the two lower limb electrodes 4 to rotate, so as to adjust the distance between the two lower limb electrodes 4. During the rotation of the lower limb electrodes 4, the lower limb electrodes 4 are always in contact with the conductive ring 702 through the conductive block 704. The electrode 4 can transmit the measurement signal to the body 1 of the body fat scale for analysis and calculation through the conductive block 704, the conductive ring 702 and the connecting line 1 703. When the distance between the two lower limb electrodes 4 is adjusted, the connecting line 3 13 can be stopped from being pulled, so that the storage shaft 807 stops rotating under the engagement of the claw 1103 and the ratchet 1102, so as to avoid the continued rotation of the storage shaft 807 affecting the position of the adjusted lower limb electrode 4. At this time, the user can move the foot from the support plate 501 to the corresponding lower limb electrode 4, and realize Each foot is completely fitted with two corresponding lower limb electrodes 4. At this time, the lower limb measurement signal can be transmitted to the body fat scale body 1 for processing and analysis through the connection between the lower limb electrodes 4, the conductive block 704, the conductive ring 702, the connecting line 1 703 and the body fat scale body 1. The upper limb measurement signal is transmitted to the body fat scale body 1 for processing and analysis through the connection between the handle 9, the connecting line 3 13, the conductive plate 1002, the conductive seat 1003, the connecting line 2 1004 and the body fat scale body 1, so that the user's body data can be completely obtained;

After the body data is detected and calculated, the body fat scale body 1 needs to be stored for easy storage. During the storage process, the user first transfers the two handles 9 on both hands to one hand for picking up, and removes the two feet from the connecting seat 2 and places them on the ground. At this time, the user needs to squat down, and move the hand that is not holding the handle 9 to one end of the two movable seats 1104, and insert the fingers into the two grooves 1106 respectively, and push the two movable seats 1104 toward each other, so that the movable seat 1104 drives the claw 1103 to move toward the spring 1105 and realize the compression of the spring 1105. When the claw 1103 moves and disengages from the ratchet 1102, the storage shaft 807 will be reset at the reset of the two torsion springs 1202. It starts to rotate under the action of elastic force, and the rotating storage shaft 807 can not only realize the reeling of the connecting wire three 13, but also drive the movable disk 3 and the lower limb electrode 4 to reset and rotate. The reeled connecting wire three 13 can drive the handle 9 to move toward the connecting seat 2. When it moves to the appropriate position, the user can respectively insert the two handles 9 into the two storage boxes 601, so that the reeled connecting wire three 13 can drive the storage box 601 to move to the connecting seat 2 through the handle 9 to realize the storage of the handle 9. In addition, the rotation of the movable disk 3 and the lower limb electrode 4 can realize the erasure of dust and sweat on the movable disk 3 and the lower limb electrode 4 under the fitting effect of the rubber pad 503, so as to prevent dust and sweat from being adsorbed on the lower limb electrode 4 and affecting the next body data detection.
