Description

[Technical field]

[0001] The utility model relates to an electrode belt pressure sensing device applied to a body fat scale. [Background Technology]

[0002] In addition to measuring body weight, existing electronic body scales have some other functions, such as measuring body fat. However, there will be certain errors when measuring body fat for different groups of people or the same person continuously at different times. The reason is that different people have different postures when measuring body fat and the strength they apply to the handle electrodes is different. In order to ensure the accuracy of body fat measurement for different groups of people, existing electronic body fat scales generally use text or video to guide users on standard measurement postures, but lack on-site prompts and guidance functions, resulting in poor user operating experience. At the same time, during the fat measurement process that lasts for tens of seconds, users are unaware of the strength with which they press the electrodes, which can easily cause the strength of their hands holding the handle to fluctuate, thereby easily affecting the accuracy of body fat measurement. [Contents of the utility model]

[0003] The utility model overcomes the shortcomings of the prior art and provides an electrode belt pressure sensing device applied to a body fat scale.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

At the same time, the utility model has a simple structure, enhances the user's operation guidance, and more intuitively prompts the user how to measure fat. [Drawings]

[0021] The technical solutions in the embodiments of the present utility model will be described clearly and completely below in conjunction with the accompanying drawings.

[0022] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In addition, the descriptions of "preferred", "sub-preferred", etc. in the present invention are only used for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "preferred" or "sub-preferred" may explicitly or implicitly include at least one of the features.

[0023] like Figure 1-4 As shown, an electrode belt pressure sensing device applied to a body fat scale includes a hand grip detection device 1, at least two hand electrodes 2 are arranged on the outer side of the hand grip detection device 1, and a pressure detection component 5 for sensing the pressing pressure of the hand electrode 2 is arranged between the hand electrode 2 and the hand grip detection device 1. By setting the pressure detection component 5 to detect the pressure of the hand electrode 2, the user is reminded to adjust the force applied to the measuring electrode to ensure that the area and force of the contact measuring electrode are within a reasonable range, thereby improving the accuracy of fat measurement.

[0024] like Figure 1-2 As shown, in this case, the hand-grip detection device 1 is a body fat detection handle; the pressure detection component 5 is a pressure-sensitive element whose pressing end is arranged on the lower side of the hand electrode 2 and the pressing end is conductive and turns on when the pressure at the pressing end reaches a set value. In actual use, both hands are held on both sides of the hand-grip detection device 1, and the hand electrodes 2 are held respectively, and at the same time, pressure is applied to the hand electrodes 2 to press the pressure-sensitive element. When the pressure at the pressing end reaches the set value, the pressure-sensitive element 5 turns on and outputs a body fat measurement signal, which reminds the user of the strength of the hand gripping handle and ensures that a reasonable range of pressing pressure is applied to the hand electrodes during the fat measurement process, thereby improving the accuracy of fat measurement.

[0025] like Figure 2 As shown, a deformable adhesive layer 3 is provided between the hand grip detection device 1 and the hand electrode 2 to mount the hand grip detection device 1, an adhesive layer through hole 4 is provided on the adhesive layer 3, and a pressure detection component 5 is arranged in the adhesive layer through hole 4. When the hand electrode 2 is pressed, the hand electrode 2 is pressed downward to deform the adhesive layer 3, so that the hand electrode 2 and the pressing end of the pressure sensing element 5 are in contact and electrically connected, and when the pressure at the pressing end reaches a set value, the pressure sensing element 5 is turned on to output a body fat measurement signal.

[0026] In this case, the height of the pressing end of the pressure detection component 5 is greater than the thickness of the adhesive layer 3; the pressing end of the pressure detection component 5 is connected to the bottom surface of the hand electrode 2 to ensure that when the hand electrode 2 is pressed, the hand electrode 2 presses the pressing end of the pressure sensing element.

[0027] like Figure 2 As shown, an electrode mounting groove 6 is provided on the outer side of the hand-grip detection device 1, and the adhesive layer 3 and the hand electrode 2 are arranged in the electrode mounting groove 6. When passing through the adhesive layer 3, the hand electrode 2 is positioned and installed in the electrode mounting groove 6; a pressure sensing element mounting groove 7 is provided on the inner bottom surface of the electrode mounting groove 6, and the pressure detection component 5 is arranged in the pressure sensing element mounting groove 7. The pressure sensing element mounting groove 7 can prevent the pressure sensing element from shifting; a handle through hole 8 is provided on the inner bottom surface of the electrode mounting groove 6 for the signal end of the pressure detection component 5 to extend into the hand-grip detection device 1, so as to facilitate the connection with the central processing unit in the main body of the body fat scale through wires to send a body fat measurement signal.

[0028] In this case, the adhesive layer 3 is electrode foam glue, the hand grip detection device 1 is a plastic handle formed by one-time injection molding, a metal handle made by die-casting process or a metal handle made by sheet metal process, and the adhesive layer 3 can also avoid the conductive connection between the hand grip detection device 1 and the hand electrode 2; the hand electrode 2 can be made of any conductive material; the pressure sensing implementation is not limited to the pressure sensing elements and quantity, and can be extended to other methods.

[0029] like Figure 1-4 As shown, in actual weighing and fat measurement, the user first stands on the scale and holds the handle. At this time, the scale automatically turns on, and the user stands upright to put pressure on the scale. The central processing unit calculates and displays the weighing data. When measuring fat, the user presses the hand electrodes on both sides of the handle with both hands to make the hand electrodes press down the pressure sensing element. When the pressure detection unit in the pressure sensing element detects that the pressure reaches the set value, the fat measurement information is sent to the central processing unit, and the fat measurement data is displayed through the scale display unit after processing. However, when the pressure detection unit in the pressure sensing element detects that the pressure is insufficient, it displays "Force NG" and prompts that the fat measurement will be re-entered after 3 seconds.

[0030] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
