And the term "and / or" used in this specification includes any and all combinations of the related items listed.

[0026] A body fat scale, also called a body fat analyzer, is a weighing device that can measure not only body weight but also fat, moisture, etc.

[0027] The human body is 60-70% water, making it a conductor in itself. Muscles in the human body are conductive, but fat is not. Body fat analyzers utilize these characteristics of the human body to measure body fat. Specifically, when measuring body fat, a body fat analyzer passes a constant electric current through the body, calculates the amount of water in the body from the impedance generated in the body under the current, then obtains the lean body mass from the relationship between the body's water content and lean body mass, and finally calculates the amount of fat and body fat percentage from the lean body mass.

[0028] Generally, body fat scales require pairing with a device such as a mobile phone. After pairing, the user can configure settings for body fat measurement using a client installed on the device, such as setting the user's height, weight, and gender.

[0029] In related technologies, settings for body fat measurement can only be made by a client installed on a terminal, making the use of body fat scales inflexible. In view of this, an embodiment of the present application provides a body fat scale and a body fat scale circuit, wherein the body fat scale includes a body fat scale body, a body fat measurement device, and a parameter setting button device, the body fat scale body includes a panel and a lower case, the panel and the lower case are connected to each other, a housing cavity exists between the panel and the lower case, and the parameter setting button device is provided in the housing cavity, so that the user does not necessarily need to make settings for body fat measurement by a client installed on a terminal such as a mobile phone, but can make settings for body fat measurement by the parameter setting button device, and the body fat scale can be used more flexibly.

[0030] Referring to Figures 1 and 2, Figure 1 is a schematic external view of the body fat analyzer provided by the embodiment of this application, and Figure 2 is an exploded view of the body fat analyzer provided by the embodiment of this application.

[0031] As shown in Figures 1 and 2, the body fat scale may include a body fat scale body, a body fat measurement device, and a parameter setting button device. Here, the body fat measurement device is for measuring body fat, and the parameter setting button device is for setting parameters, where the parameters include parameters necessary for measuring body fat, user parameters, user preference parameters, and operating parameters of the body fat scale. For example, parameters necessary for measuring body fat may include the user's height and gender, user parameters may include the user's account and account password, user preference parameters may include the user's preferred measurement method, and operating parameters of the body fat scale may include the standby time of the body fat scale, the content to be displayed on the display screen of the body fat scale, and the default measurement mode of the body fat scale. However, the embodiments of this application do not specifically limit these.

[0032] Here, the body fat analyzer body may include a panel 101 and a lower case 102, the panel 101 may be a glass panel, the panel 101 and the lower case 102 are connected to each other, and optionally, the panel 101 and the lower case 102 may be fixedly connected or detachably connected. After the panel 101 and the lower case 102 are connected, a housing cavity can be formed between the panel 101 and the lower case 102.

[0033] As shown in Figure 2, the lower case 102 has multiple mounting through holes 103 (although only two mounting through holes 103 are shown in Figure 2, it should be understood that more than two mounting through holes 103, for example four mounting through holes 103, may actually be provided), and multiple support parts 104 can be attached to these multiple mounting through holes 103.

[0034] As shown in Figure 2, the support portion 104 includes a first support portion 1041, a support leg 1042, a washer 1043, and a rubber pad 1044, wherein the support surface of the first support portion 1041 is in contact with the panel 101, and this contact may be direct or indirect through other members, and the other surface of the first support portion 1041 facing the support surface is connected to one end of the support leg 1042, and the other end of the support leg 1042 is connected to the rubber pad 1044 via the washer 1043.

[0035] Here, the first support portion 1041 is housed in a housing cavity formed between the panel 101 and the lower case 102, part or all of the support leg 1042 is housed in a housing cavity formed between the panel 101 and the lower case 102, and the rubber pad 1044 is located outside the lower case 1042, and when the body fat scale is placed on a flat surface, the rubber pad 1044 comes into contact with the surface and acts as an anti-slip surface.

[0036] Continuing to refer to Figure 2, in a preferred embodiment of the present application, a sensor 105 may be provided between the first support portion 1041 and the support leg 1042. For example, the sensor 105 may be a pressure sensor, and the pressure sensor 105 can be used to measure the weight of a user standing on the body fat scale.

[0037] Referring to Figures 1 and 2, the body fat measuring device in the body fat scale includes two pairs of electrode plates 106 fitted into a panel 101, each pair of electrode plates 106 including a first electrode plate 1061 and a second electrode plate 1062, and the panel 101 includes two body fat measurement areas (which may be areas indicated by dashed lines in Figure 1) that correspond one-to-one with the two pairs of electrode plates 106. When measuring body fat, the two body fat measurement areas are used to place parts of the user's body being measured, for example, the two body fat measurement areas may be foot areas, and when measuring body fat, the two body fat measurement areas are used to place the user's feet, allowing the user's feet to come into contact with the pairs of electrode plates 106 in the body fat measurement areas, thereby enabling the measurement of body fat.

[0038] In preferred embodiments of this application, the body fat analyzer may further include a body fat detection circuit (not shown in Figure 2) connected to the two electrode plate pair 106, which may be in the form of a control chip, a single-chip microcontroller, an MCU (Microcontroller Unit), etc., and 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 are not specifically limited thereto.

[0039] In a preferred embodiment of this application, the body fat detection circuit may be provided on a circuit board D that can be housed in a housing cavity formed between the panel 101 and the lower case 102.

[0040] In a preferred embodiment of this application, the circuit board D may further be provided with a main control circuit, which may be in the form of a control chip, a single-chip microcontroller, an MCU, etc., and the body fat detection circuit may be connected to the main control circuit. In a preferred embodiment of this application, the body fat detection circuit and the main control circuit may be designed as an integral part of the same structure, but the embodiments of this application are not specifically limited thereto.

[0041] Referring to Figure 2, the parameter setting button device included in the body fat scale provided in the embodiment of this application may be provided in a housing cavity formed between the panel 101 and the lower case 102, and the panel 101 has a touch area C corresponding to the parameter setting button device, and the parameter setting button device is triggered when the corresponding touch area C is touched.

[0042] In a preferred embodiment of the present application, the body fat scale includes one or more parameter setting button devices, each of which may respond differently after being triggered. For example, in one preferred embodiment, the body fat scale includes three parameter setting button devices: a setting button, an up adjustment button, and a down adjustment button. Correspondingly, the panel 101 may have three touch areas C, including a touch area corresponding to the setting button, a touch area corresponding to the up adjustment button, and a touch area corresponding to the down adjustment 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 adjustment button is touched, the up adjustment button is triggered; and when the touch area corresponding to the down adjustment button is touched, the down adjustment button is triggered.

[0043] In a preferred embodiment of the present application, the touch area C in panel 101 may be located between the two body fat measurement areas, and the touch area C is close to the first electrode plate 1061 in the pair of electrode plates 106 and spaced apart from the second electrode plate 1062 in the pair of electrode plates 105.

[0044] Referring to Figures 1 and 2, in a preferred embodiment of the present application, a display screen 107 may be further fitted to the panel 101, and the touch area C may be located below the display screen 107 in the direction from the second electrode plate 1062 toward the first electrode plate 1061.

[0045] By positioning the touch area C as described above, when a user measures body fat (in this case, with both of the user's feet on the body fat measurement area of ​​panel 101), they can easily touch the touch area C to trigger the parameter setting button device and cause the body fat scale to respond accordingly. At the same time, it is possible to ensure that the user's body parts do not come into contact with the touch area C when the user measures body fat, thus preventing accidental touches.

[0046] Referring to Figure 2, in a preferred embodiment of the present application, the parameter setting button device may include a touch electrode 108 and a touch detection circuit (not shown in Figure 2) connected to each other. Here, the touch electrode 108 is located below the touch area C in a first direction which is from the lower case 102 toward the panel 101, and the touch detection circuit may be in the form of a control chip, a single-chip microcontroller, an MCU, etc. The touch detection circuit may be provided on a circuit board D, and in a preferred embodiment of the present application, the touch detection circuit may be connected to a main control circuit, and optionally, the touch detection circuit and the main control circuit may be designed as an integral part of the present application, but the embodiments of the present application are not specifically limited thereto.

[0047] Furthermore, if the body fat scale includes multiple parameter setting button devices, each parameter setting button device includes a touch electrode 108, and the touch electrodes 108 included in each parameter setting button device may be located below the touch area C corresponding to each parameter setting button device in the first direction.

[0048] In one preferred embodiment, the multiple parameter setting button devices may share a single touch detection circuit, and each of the multiple touch electrodes 108 may be connected to the touch detection circuit; in another preferred embodiment, each of the multiple parameter setting button devices may include a single touch detection circuit, and the touch electrodes 108 included in each parameter setting button device and the touch detection circuit may be connected to each other.

[0049] In a preferred embodiment of this application, a capacitance Cx exists between the touch electrode 108 and ground. When a part of the human body touches a touch area C located above the touch electrode 108, the capacitance Cx between the touch electrode 108 and ground changes, and the amount of charge on the touch electrode 108 changes accordingly. The touch detection circuit can determine whether or not the touch area C has been touched simply by detecting the change in the amount of charge on the touch electrode 108.

[0050] In a preferred embodiment of this application, as shown in Figure 2, the parameter setting button device may further include a light-emitting assembly 109 and a light-diffusing film 110.

[0051] Here, the light-emitting assembly 109 is provided on the circuit board D, and the light-emitting assembly 109 may be, for example, an LED bead, and the light-emitting surface of the light-emitting assembly 109 faces the panel 101, that is, the light-emitting assembly 109 can emit light rays toward the panel 101, and the light-emitting assembly 109 is connected to the main control circuit on the circuit board D and can be operated by the control of the main control circuit.

[0052] The light-diffusing film 110 is provided in the light-emitting path between the light-emitting assembly 109 and the panel 110, and the light-diffusing film 110 includes a light-transmitting region and a non-light-transmitting region, wherein the light transmittance of the light-transmitting region is greater than the light transmittance of the non-light-transmitting region, and in a first direction, the light-transmitting region is located below the touch region C, and in a preferred embodiment of this application, the shape of the light-transmitting region is the shape of a button presentation icon.

[0053] Since the light-diffusing film 110 is provided in the light-emitting path between the light-emitting assembly 109 and the panel 110, and the light-diffusing film 110 includes a light-transmitting region located below the touch region C in a first direction, after the light-emitting assembly 109 emits light rays, the light rays emitted from the light-emitting assembly 109 can be emitted to the touch region C through the light-transmitting region of the light-diffusing film 110. In a preferred embodiment, the shape of the light-transmitting region of the light-diffusing film 110 is the shape of a button presentation icon, so that a spot matching the shape of the button presentation icon can be formed in the touch region C, and this spot can indicate to the user that they should touch the touch region C when it is necessary to trigger the parameter setting button device.

[0054] Furthermore, if the body fat scale includes multiple parameter setting button devices, these multiple parameter setting button devices may share a single light-diffusing film 110, and the light-diffusing film 110 may be provided with multiple light-transmitting regions that correspond one-to-one with the multiple parameter setting button devices. The shapes of these multiple light-transmitting regions can be the shapes of button display icons corresponding to different parameter setting button devices. For example, the button display icon corresponding to the setting button may be the letter "set", the button display icon corresponding to the down adjustment button may be a downward-pointing arrow, and the button display icon corresponding to the up adjustment button may be an upward-pointing arrow.

[0055] As can be understood from the above explanation, the button prompt icons displayed in the touch area C of panel 101 are actually formed by spots. Therefore, when the body fat scale is turned off, that is, when the light-emitting assembly 109 is not operating, panel 101 is represented as a single visual effect, and the button prompt icons in the touch area C cannot be seen with the naked eye. Of course, in some possible embodiments, the touch area C of panel 101 may be provided with button prompt icons that overlap with the spot-formed button prompt icons by one of several methods, such as etching or ink spraying. This allows the non-illuminated button prompt icons to be seen with the naked eye in the touch area C even when the light-emitting assembly 109 is not operating.

[0056] In a preferred embodiment of the present application, if the body fat scale includes a plurality of parameter setting button devices, the plurality of parameter setting button devices may share one light-emitting assembly 109, or the plurality of parameter setting button devices may share a plurality of light-emitting assemblies 109, and the number of the plurality of light-emitting assemblies 109 may be the same as, less than, or more than the number of parameter setting button devices.

[0057] Furthermore, the light-diffusing film 110 has a light-diffusing function, which makes the light emitted from the light-emitting assembly 109 to the panel 101 more uniform and softer.

[0058] In a preferred embodiment of this application, the touch detection electrode 108 is provided between the light-emitting assembly 109 and the light-diffusing film 110, and the touch detection electrode 108 includes an optical path through hole located in the light-emitting optical path between the light-emitting assembly 109 and the light-transmitting region of the light-diffusing film 110, so that light rays emitted from the light-emitting assembly 109 can be emitted through the optical path through hole of the touch detection electrode 108 to the light-transmitting region of the light-diffusing film 110.

[0059] In a preferred embodiment of this application, the touch detection electrode 108 may be an annular electrode, or it may be a touch spring including a coiled conductor. Since the coiled conductor can carry more charge, the degree of charge change is also larger, which allows the touch detection circuit to detect a relatively significant charge change signal and improve the sensitivity of touch detection.

[0060] In a preferred embodiment of the present application, the parameter setting button device further includes a light-shielding cap 111 provided between the light-emitting assembly 109 and the light-diffusing film 110. The light-shielding cap 111 includes a light-shielding cap through-hole, a housing groove is provided around the light-shielding cap through-hole, a touch detection electrode 108 is housed in the housing groove, the optical path through-hole of the touch detection electrode 108 is provided toward the light-shielding cap through-hole, the light-shielding cap through-hole is located in the light-emitting optical path between the light-emitting assembly 109 and the light-transmitting region of the light-diffusing film 110, and light rays emitted from the light-emitting assembly 109 can exit through the light-shielding cap through-hole to the light-transmitting region of the light-diffusing film 110.

[0061] Furthermore, if the body fat scale includes multiple parameter setting button devices, these multiple parameter setting button devices may share a single light-shielding cap 111. In this case, the light-shielding cap 111 includes multiple light-shielding cap through-holes that correspond one-to-one with the multiple parameter setting button devices, and each light-shielding cap through-hole is provided with a housing groove. The touch detection electrode 108 corresponding to each parameter setting button device may be housed in the housing groove provided around the light-shielding cap through-hole corresponding to that parameter setting button device.

[0062] In a preferred embodiment of the present application, the body fat scale may further include a power on / off button device, the power on / off button device being located on the side of the lower case 102 away from the panel 101, that is, when the body fat scale is left in a normal state, the power on / off button device is located at the bottom of the body fat scale.

[0063] In a preferred embodiment of this application, the power on / off button device is for triggering the power on and / or off of the body fat scale.

[0064] In a preferred embodiment of the present application, the power on / off button device includes one button device, in which case, when the button device is triggered, if the body fat meter is in the ON state, the body fat meter turns OFF in response to the trigger of the button device, and similarly, when the button device is triggered, if the body fat meter is in the OFF state, the body fat meter turns ON in response to the trigger of the button device.

[0065] In a preferred embodiment of the present application, the power on / off button device includes two button devices, one of which is a power on button for triggering the body fat scale to be powered on, and the other button device is a power off button for triggering the body fat scale to be powered off, wherein when the body fat scale is in the off state, the body fat scale turns on in response to the trigger of the power on button, and when the body fat scale is in the on state, the body fat scale turns off in response to the trigger of the trigger of the power off button.

[0066] Embodiments of this application further provide a body fat analyzer circuit, which may optionally be provided in a body fat analyzer as shown in Figure 1 or Figure 2, and referring to Figure 3, the body fat analyzer circuit includes a body fat measurement circuit 301, a parameter setting button circuit 302, and a main control circuit 303, where the body fat measurement circuit 301 is for measuring body fat. In a preferred embodiment of this application, the body fat analyzer circuit may include a plurality of parameter setting button circuits 302 provided in a housing cavity formed by the panel of the body fat analyzer and the lower case of the body fat analyzer. In a preferred embodiment of this application, the panel has touch areas corresponding to the parameter setting button circuits, and the parameter setting button circuits can be triggered when the touch areas are touched.

[0067] The main control circuit 303 is connected to the body fat measurement circuit 301 and the parameter setting button circuit 302, respectively. The main control circuit 303 can receive a measurement signal transmitted from the body fat measurement circuit 301 and generate a body fat measurement result based on the measurement signal. The main control circuit 303 can also receive a trigger signal output after the parameter setting button circuit 302 is triggered and respond to the trigger signal.

[0068] Referring to Figure 4, in a preferred 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, where the touch detection circuit 3022 is connected to the main control circuit 303, and in a preferred embodiment of this application, the touch detection circuit 3022 detects charge change data at the touch electrode 3021 and outputs a trigger signal to the main control circuit 303 when it detects that the charge change data satisfies the trigger condition. In a preferred embodiment of this application, the touch detection electrode 3021 is a touch spring. Note that the touch electrode 3021 and the touch detection circuit 3022 have already been described in the above embodiment, so a redundant explanation of the embodiment of this application will be omitted here.

[0069] Furthermore, if the body fat scale circuit includes multiple parameter setting button circuits 302, each of the multiple parameter setting button circuits 302 may include one touch electrode 3021. In one preferred embodiment, the multiple parameter setting button circuits 302 may share one touch detection circuit 3022, and the touch detection circuit 3022 may be connected to each of the multiple touch electrodes 3021. In another preferred embodiment, each of the multiple parameter setting button circuits 302 may be provided with one 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 connected to each other.

[0070] In one preferred embodiment, the body fat scale may be provided with three parameter setting button devices: a setting button, an up adjustment button, and a down adjustment button. Therefore, the body fat scale circuit may correspondingly include three parameter setting button circuits 302: a setting parameter setting button circuit, an up adjustment parameter setting button circuit, and a down adjustment parameter setting button circuit. Hereinafter, the main control circuit 303 will be briefly described in the embodiments of this application as responding to trigger signals output from these three parameter setting button circuits.

[0071] The touch detection circuit 3022 can transmit a first trigger signal to the main control circuit 303 when it detects that the setting button has been triggered. When the main control circuit 303 receives the first trigger signal, it can detect whether the body fat scale is in setting mode. If the body fat scale is not in setting mode, it can proceed to setting mode and display a setting menu interface on the display screen. If the body fat scale is in setting mode, it can control the display screen to switch from the currently displayed setting menu interface to another setting menu interface, or to switch setting parameters within the currently displayed setting menu interface. In a preferred embodiment of this application, the setting menu interface can be understood as a weight setting menu interface for setting weight parameters, a height setting menu interface for setting height parameters, and a gender setting menu interface for setting gender.

[0072] When the touch detection circuit 3022 detects that the up adjustment 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 detects whether the body fat scale is in setting mode. If the body fat scale is not in setting mode, it does not respond. If the body fat scale is in setting mode, it can adjust the current setting parameters (e.g., height, weight, gender) up.

[0073] When the touch detection circuit 3022 detects that the down adjustment 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 detects whether the body fat scale is in setting mode. If the body fat scale is not in setting mode, it does not respond. If the body fat scale is in setting mode, it can adjust the current setting parameters (e.g., height, weight, gender) down.
