[0037] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0039] It is understood that the terms "first," "second," etc., used herein may be used to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, without departing from the scope of this application, a first resistor may be referred to as a second resistor, and similarly, a second resistor may be referred to as a first resistor. Both the first resistor and the second resistor are resistors, but they are not the same resistor.

[0040] It is understood that the term "connection" in the following embodiments should be understood as "electrical connection," "communication connection," etc., if the connected circuits, modules, units, etc., have electrical signal or data transmission with each other.

[0041] It is understandable that "at least one" refers to one or more, and "multiple" refers to two or more. "At least a part of an element" refers to part or all of an element.

[0042] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising / including” or “having,” etc., specify the presence of the stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. Meanwhile, the term “and / or” as used in this specification includes any and all combinations of the associated listed items.

[0043] A body fat scale, also known as a body fat scale, is a weighing device that can measure not only weight but also fat, water, and other substances.

[0044] The human body is composed of 60-70% water, making it a conductor. Muscles conduct electricity, while fat does not. Body fat scales utilize this property to measure body fat. Specifically, during measurement, a certain current is passed through the body. The scale calculates the water content based on the impedance generated by the current. Then, by considering the relationship between body water and lean body mass, the lean body mass is obtained. Finally, the body fat percentage and fat mass can be calculated from this lean body mass.

[0045] Generally, body fat scales need to be paired with mobile phones or other devices. After pairing, users can configure body fat measurement through the client installed on the device, such as configuring the height, weight, and gender of the user to be measured.

[0046] Because related technologies only allow configuration of body fat measurements via a client installed on a terminal, the use of body fat scales is inflexible. In view of this, this application provides a body fat scale and a body fat scale circuit. The body fat scale includes a scale body, a body fat measuring device, and a parameter setting button device. The scale body includes a panel and a bottom shell, which are connected to each other. A cavity exists between the panel and the bottom shell, and the parameter setting button device is disposed within this cavity. Because the parameter setting button device is provided on the scale body, users can configure body fat measurements directly using this button device, without having to configure them via a client installed on a mobile phone or other terminal, thus allowing for more flexible use of the body fat scale.

[0047] Please refer to Figure 1 Figure 2 ,in, Figure 1 This is a schematic diagram of the appearance of the body fat scale provided in an embodiment of this application. Figure 2 An exploded view of the body fat scale provided in an embodiment of this application.

[0048] like Figure 1 and Figure 2 As shown, the body fat scale may include a body fat scale body, a body fat measurement device, and a parameter setting button device. The body fat measurement device is used to measure body fat; the parameter setting button device is used to set parameters, which may include: parameters required for body fat measurement, user parameters, user preference parameters, and operating parameters of the body fat scale. For example, parameters required for body fat measurement may include the user's height and gender; user parameters may include the user's account and password; user preference parameters may include the user's preferred measurement method; and the operating parameters of the body fat scale may include the standby time of the body fat scale, the content to be displayed on the body fat scale's screen, and the default measurement mode of the body fat scale. This embodiment of the application does not specifically limit these parameters.

[0049] The body fat scale may include a panel 101 and a base 102. The panel 101 may be a glass panel. The panel 101 and the base 102 are connected to each other. Optionally, the panel 101 and the base 102 may be fixedly connected or detachably connected. After the panel 101 and the base 102 are connected, a receiving cavity can be formed between the panel 101 and the base 102.

[0050] like Figure 2 As shown, multiple mounting through holes 103 can be formed on the bottom shell 102. Figure 2 Only two mounting through holes 103 are shown, but the reader should understand that more than two mounting through holes 103 can actually be made (for example, four mounting through holes 103 can be made), and multiple support parts 104 can be installed based on these multiple mounting through holes 103.

[0051] like Figure 2 As shown, the support portion 104 may include a first support portion 1041, a scale foot bracket 1042, a pad 1043, and a rubber pad 1044. The support surface of the first support portion 1041 is in contact with the panel 101. This contact may be direct contact or indirect contact through other components. The other side of the first support portion 1041 opposite to the support surface is connected to one end of the scale foot bracket 1042. The other end of the scale foot bracket 1042 is connected to the rubber pad 1044 through the pad 1043.

[0052] The first support 1041 is housed in the cavity formed between the panel 101 and the bottom shell 102. Part or all of the scale foot bracket 1042 is housed in the cavity formed between the panel 101 and the bottom shell 102. The rubber pad 1044 is located outside the bottom shell 1042. When the body fat scale is placed on a certain plane, the rubber pad 1044 contacts the plane to play a role in preventing slippage.

[0053] Please continue to refer to this. Figure 2 In an optional embodiment of this application, a sensor 105 may be provided between the first support 1041 and the scale foot bracket 1042. For example, the sensor 105 may be a pressure sensor, which can be used to measure the weight of a user standing on the body fat scale.

[0054] Please refer to Figure 1 and Figure 2 The body fat measuring device in the body fat scale may include two pairs of electrode pads 106 embedded in the panel 101. Each pair of electrode pads 106 includes a first electrode pad 1061 and a second electrode pad 1062. The panel 101 includes two body fat measuring areas corresponding to the two pairs of electrode pads 106 (the body fat measuring area can be...). Figure 1 (The area shown by the dashed line) During body fat measurement, the two body fat measurement areas support the body parts of the user being measured. For example, the two body fat measurement areas can be foot support areas. During body fat measurement, the two body fat measurement areas can support the user's feet, and the user's feet can contact the electrode pads 106 in the body fat measurement areas to achieve body fat measurement.

[0055] In an optional embodiment of this application, the body fat scale may further include a body fat detection circuit connected to the two pairs of electrode pads 106. Figure 2 (Not shown), the body fat detection circuit can take the form of a control chip, a microcontroller, an MCU (Microcontroller Unit), etc. The body fat detection circuit may include, for example, a detection current generation circuit, a detection current transmission circuit, an impedance detection circuit, etc., but the embodiments of this application do not specifically limit it.

[0056] In an optional embodiment of this application, the body fat detection circuit can be disposed on a circuit board D, which can be housed in a receiving cavity formed between the panel 101 and the bottom shell 102.

[0057] In an optional embodiment of this application, a main control circuit may also be provided on the circuit board D. The main control circuit may be in the form of a control chip, a microcontroller, an MCU, etc. The body fat detection circuit may be connected to the main control circuit. In an optional embodiment of this application, the body fat detection circuit and the main control circuit may be an integrated design. This application does not specifically limit this aspect.

[0058] Please refer to Figure 2 The parameter setting button device included in the body fat scale provided in this application embodiment can be disposed in the receiving cavity formed between the panel 101 and the bottom shell 102. There is a touch area C on the panel 101 corresponding to the parameter setting button device. The parameter setting button device can be triggered when its corresponding touch area C is touched.

[0059] In an optional embodiment of this application, the body fat scale may include one or more parameter setting button devices. Each parameter setting button device can perform different responses after being triggered. For example, in an optional embodiment, the body fat scale may include three parameter setting button devices, namely a setting button, an up button, and a down button. Correspondingly, there may be three touch areas C on the panel 101. The three touch areas C include a touch area corresponding to the setting button, a touch area corresponding to the up button, and a touch area corresponding to the down button. It can be understood that when the touch area corresponding to the setting button is touched, the setting button is triggered. Similarly, when the touch area corresponding to the up button is touched, the up button is triggered. When the touch area corresponding to the down button is touched, the down button is triggered.

[0060] In an optional embodiment of this application, the touch area C on the panel 101 may be located between the two body fat measurement areas described above, and the touch area C is close to the first electrode 1061 of the two pairs of electrode sheets 106 and far away from the second electrode 1062 of the two pairs of electrode sheets 105.

[0061] Please refer to Figure 1 and Figure 2 In an optional embodiment of this application, a display screen 107 is also embedded on the panel 101, and the touch area C can be located below the display screen 107 in the direction from the second electrode plate 1062 to the first electrode plate 1061.

[0062] Setting the touch area C in the position described above allows the user to conveniently touch the touch area C while measuring body fat (when the user's feet are on the body fat measurement area of ​​panel 101), thereby triggering the parameter setting button device and causing the body fat scale to respond accordingly. At the same time, it also ensures that the user's body parts will not come into contact with the touch area C while measuring body fat, thus avoiding accidental touches.

[0063] Please refer to Figure 2 In an optional embodiment of this application, the parameter setting button device may include interconnected touch electrodes 108 and touch detection circuit (…). Figure 2 (Not shown in the image). In the first direction, the touch electrode 108 is located below the touch area C, and the first direction is from the bottom shell 102 towards the panel 101. The touch detection circuit can be a control chip, a microcontroller, an MCU, etc., and can be mounted on the circuit board D. In an optional embodiment of this application, the touch detection circuit can be connected to the main control circuit. Optionally, the touch detection circuit and the main control circuit can be an integrated design; this application does not specifically limit this aspect.

[0064] It should be noted that when the body fat scale includes multiple parameter setting buttons, each parameter setting button may include a touch electrode 108, and the touch electrode 108 included in each parameter setting button is located below the touch area C corresponding to each parameter setting button in the first direction.

[0065] In one optional implementation, the multiple parameter setting button devices can share a single touch detection circuit, and the multiple touch electrodes 108 are all connected to the touch detection circuit. In another optional implementation, the multiple parameter setting button devices can each include a touch detection circuit, and the touch electrodes 108 and touch detection circuits included in each parameter setting button device can be interconnected.

[0066] In an optional embodiment of this application, there is a capacitance Cx between the touch electrode 108 and ground. When a human body touches the touch area C above the touch electrode 108, the capacitance Cx between the touch electrode 108 and ground will change, and the amount of charge on the touch electrode 108 will also change accordingly. The touch detection circuit can determine whether the touch area C has been touched by detecting the change in the amount of charge on the touch electrode 108.

[0067] like Figure 2 As shown, in an optional embodiment of this application, the parameter setting button device may further include a light-emitting component 109 and a diffuser film 110.

[0068] The light-emitting component 109 is disposed on the circuit board D. The light-emitting component 109 can be, for example, an LED lamp bead. The light-emitting surface of the light-emitting component 109 faces the panel 101. That is, the light-emitting component 109 can emit light towards the panel 101. The light-emitting component 109 can be connected to the main control circuit on the circuit board D and work under the control of the main control circuit.

[0069] A diffuser film 110 is disposed on the light path between the light-emitting component 109 and the panel 110. The diffuser film 110 may include a light-transmitting area and a non-light-transmitting area. The light transmittance of the light-transmitting area is greater than that of the non-light-transmitting area. In a first direction, the light-transmitting area is located below the touch area C. In an optional embodiment of this application, the shape of the light-transmitting area is the shape of a button prompt icon.

[0070] Since the diffuser film 110 is disposed on the light path between the light-emitting component 109 and the panel 110, and the diffuser film 110 includes a light-transmitting area located below the touch area C in the first direction, after the light-emitting component 109 emits light, the light emitted by the light-emitting component 109 can be directed to the touch area C through the light-transmitting area of ​​the diffuser film 110. Since in the optional embodiment, the shape of the light-transmitting area of ​​the diffuser film 110 is the shape of the button prompt icon, a light spot with the same shape as the button prompt icon can be formed on the touch area C. The light spot can prompt the user to touch the touch area C when the parameter setting button device needs to be triggered.

[0071] It should be noted that when the body fat scale includes multiple parameter setting buttons, these multiple parameter setting buttons can share a single diffuser film 110. The diffuser film 110 can be provided with multiple light-transmitting areas that correspond one-to-one with each of the multiple parameter setting buttons. The shapes of these multiple light-transmitting areas are the shapes of the button prompt icons corresponding to different parameter setting buttons. For example, the button prompt icon corresponding to the set button can be the English letter "set", the button prompt icon corresponding to the down button can be a downward arrow, and the button prompt icon corresponding to the up button can be an upward arrow.

[0072] As explained above, the button prompt icons displayed on the touch area C of panel 101 are actually formed by light spots. Therefore, when the body fat scale is powered off, that is, when the light-emitting component 109 is not working, panel 101 presents a unified visual effect, and the button prompt icons cannot be seen with the naked eye on touch area C. Of course, in some possible embodiments, button prompt icons can also be set on touch area C of panel 101 by etching, ink spraying, or other methods. These button prompt icons overlap with the button prompt icons formed by the light spots. In this way, even when the light-emitting component 109 is not working, the non-illuminated button prompt icons can be observed with the naked eye on touch area C.

[0073] In an optional embodiment of this application, when the body fat scale includes multiple parameter setting button devices, the multiple parameter setting button devices may share a single light-emitting component 109, or the multiple parameter setting button devices may share multiple light-emitting components 109, and the number of the multiple light-emitting components 109 may be less than, equal to or greater than the number of parameter setting button devices.

[0074] It should be noted that the diffuser film 110 has the function of diffused light, which can make the light emitted from the light-emitting component 109 onto the panel 101 more uniform and softer.

[0075] In an optional embodiment of this application, a touch electrode 108 is disposed between the light-emitting component 109 and the diffuser film 110. The touch electrode 108 includes a light path through-hole, which is located on the light-emitting light path between the light-emitting component 109 and the light-transmitting area of ​​the diffuser film 110. The light emitted by the light-emitting component 109 can be emitted through the light path through the touch electrode 108 onto the light-transmitting area of ​​the diffuser film 110.

[0076] In an optional embodiment of this application, the touch electrode 108 can be a ring electrode, or the touch electrode 108 can be a touch spring. The touch spring can contain a spiral conductor. Since the spiral conductor can carry more charge, the magnitude of its charge change will also be larger. In this way, the touch detection circuit can detect a more obvious charge change signal, thereby increasing the sensitivity of touch detection.

[0077] In an optional embodiment of this application, the parameter setting button device further includes a light shield 111, which is disposed between the light-emitting component 109 and the diffuser film 110. The light shield 111 includes a light shield through-hole, and a receiving groove is provided around the light shield through-hole. The touch electrode 108 is housed in the receiving groove, and the optical path through-hole of the touch electrode 108 is disposed facing the light shield through-hole. The light shield through-hole is located on the light-emitting optical path between the light-emitting component 109 and the light-transmitting area of ​​the diffuser film 110. The light emitted by the light-emitting component 109 can be emitted through the light shield through-hole onto the light-transmitting area of ​​the diffuser film 110.

[0078] It should be noted that when the body fat scale includes multiple parameter setting buttons, these multiple parameter setting buttons can share a single light shield 111. In this case, the light shield 111 can include multiple light shield through holes corresponding one-to-one with the multiple parameter setting buttons. Each light shield through hole is surrounded by a receiving groove, and the touch electrode 108 corresponding to each parameter setting button is housed in the receiving groove surrounding the light shield through hole corresponding to that parameter setting button.

[0079] In an optional embodiment of this application, the body fat scale may further include a power on / off button device, wherein the power on / off button device is disposed on the side of the bottom shell 102 away from the panel 101, that is, when the body fat scale is placed normally, the power on / off button device is located at the bottom of the body fat scale.

[0080] In an optional embodiment of this application, the power button is used to trigger the body fat scale to power on and / or power off.

[0081] In an optional embodiment of this application, the power on / off button device includes a button device. In this case, when the button device is triggered, if the body fat scale is in the power-on state, the body fat scale will enter the power-off state in response to the triggering of the button device. Similarly, when the button device is triggered, if the body fat scale is in the power-off state, the body fat scale will enter the power-on state in response to the triggering of the button device.

[0082] In an optional embodiment of this application, the power on / off button device includes two button devices, one of which is a power button used to trigger the body fat scale to power on, and the other is a power off button used to trigger the body fat scale to power off. When the body fat scale is in the power off state, if the power button is triggered, the body fat scale will enter the power on state in response to the triggering of the power button. When the body fat scale is in the power on state, if the power off button is triggered, the body fat scale will enter the power off state in response to the triggering of the power off button.

[0083] This application embodiment also provides a body fat scale circuit, optionally, the body fat scale circuit can be set as follows: Figure 1 or Figure 2 Please refer to the body fat scale shown. Figure 3 The body fat scale circuit includes a body fat measurement circuit 301, a parameter setting button circuit 302, and a main control circuit 303. The body fat measurement circuit 301 is used to measure body fat. In an optional embodiment of this application, the body fat scale circuit may include multiple parameter setting button circuits 302, wherein the parameter setting button circuits 302 are disposed within a receiving cavity formed by the panel and the bottom shell of the body fat scale. In an optional embodiment of this application, a touch area corresponding to the parameter setting button circuit exists on the panel, and the parameter setting button circuit can be triggered when the touch area is touched.

[0084] The main control circuit 303 is connected to both the body fat measurement circuit 301 and the parameter setting button circuit 302. The main control circuit 303 can receive the measurement signal sent by the body fat measurement circuit 301 and generate the body fat measurement result based on the measurement signal. The main control circuit 303 can also receive the trigger signal output by the parameter setting button circuit 302 after it is triggered and respond to the trigger signal.

[0085] Please refer to Figure 4In an optional embodiment of this application, the parameter setting button circuit 302 may include a touch electrode 3021 and a touch detection circuit 3022 connected to each other. The touch detection circuit 3022 is connected to the main control circuit 303. In this optional embodiment, the touch detection circuit 3022 detects changes in charge on the touch electrode 3021 and outputs a trigger signal to the main control circuit 303 when the detected change in charge meets the trigger condition. In an optional embodiment of this application, the touch electrode 3021 is a touch spring. It should be noted that the touch electrode 3021 and the touch detection circuit 3022 have been described in the above embodiments, and will not be explained redundantly here.

[0086] It should be noted that when the body fat scale circuit includes multiple parameter setting button circuits 302, each of the multiple parameter setting button circuits 302 may include a touch electrode 3021. In one optional implementation, the multiple parameter setting button circuits 302 may share a single touch detection circuit 3022, which may be connected to all of the multiple touch electrodes 3021. In another optional implementation, each of the multiple parameter setting button circuits 302 may have its own touch detection circuit 3022, and the touch electrodes 3021 and touch detection circuits 3022 included in the same parameter setting button circuit 302 may be interconnected.

[0087] In one optional embodiment, the body fat scale can be equipped with three parameter setting buttons: a set button, an up button, and a down button. The body fat scale circuit can then include three parameter setting button circuits 302: a set parameter setting button circuit, an up parameter setting button circuit, and a down parameter setting button circuit. Below, this application embodiment will briefly describe how the main control circuit 303 responds to the trigger signals output by these three parameter setting button circuits.

[0088] When the touch detection circuit 3022 detects that the setting button has been triggered, it can send a first trigger signal to the main control circuit 303. Upon receiving the first trigger signal, the main control circuit 303 can detect whether the body fat scale is in setting mode. If the body fat scale is not in setting mode, it enters setting mode and displays the setting menu interface on the display screen. If the body fat scale is in setting mode, it controls the display screen to switch from the currently displayed setting menu interface to another setting menu interface, or controls the display screen to switch setting parameters in the currently displayed setting menu interface. In an optional embodiment of this application, the setting menu interface can be understood as a weight setting menu interface, a height setting menu interface, and a gender setting menu interface. The weight setting menu interface can be used to set weight parameters, the height setting menu interface can be used to set height parameters, and the gender setting menu interface can be used to set gender.

[0089] When the touch detection circuit 3022 detects that the up button has been triggered, it can send a second trigger signal to the main control circuit 303. When the main control circuit 303 receives the second trigger signal, it can detect whether the body fat scale is in the setting mode. If the body fat scale is not in the setting mode, it will not respond. If the body fat scale is in the setting mode, it will increase the current setting parameters (e.g., height, weight, gender).

[0090] When the touch detection circuit 3022 detects that the down button has been triggered, it can send a third trigger signal to the main control circuit 303. When the main control circuit 303 receives the third trigger signal, it can detect whether the body fat scale is in the setting mode. If the body fat scale is not in the setting mode, it will not respond. If the body fat scale is in the setting mode, it will lower the current setting parameters (e.g., height, weight, gender).
