Technical Field

[0001] This application relates to the field of pet body fat detection technology, specifically to a pet body fat scale. Background Technology

[0002] Bioelectrical impedance analysis can be used to quickly and conveniently assess a pet's obesity status, thereby enabling the development of a reasonable health management plan for the pet.

[0003] However, bioelectrical impedance values ​​are affected by a variety of factors and vary from person to person, resulting in low accuracy in assessing pet obesity. These factors include changes in body water content (such as dehydration or increased water intake), changes in body temperature and room temperature, and differences in body size, age, and sex. Utility Model Content

[0004] In view of this, the present invention provides a pet body fat scale to solve the problem of low accuracy in the assessment of pet obesity in the prior art.

[0005] Therefore, the pet body fat scale provided by this utility model includes a base and also includes:

[0006] The body fat percentage calculation module includes a pet body fat percentage calculation model, which is constructed from multiple sets of body shape data, electrical impedance data, and body fat percentage data of different breeds of pets.

[0007] The data acquisition device is used to collect pet characteristic data, body size data, and electrical impedance data. The pet characteristic data includes the pet's breed and age, and the pet's body size data includes the pet's body length, body width, shoulder height, and weight.

[0008] The body fat percentage calculation module calculates the current pet's body fat percentage using the pet body fat percentage calculation model based on the pet's current characteristic data, body shape data, and electrical impedance data.

[0009] Based on the above technical solutions, the pet body fat percentage calculation model in this application is constructed using multiple sets of body shape data, electrical impedance data and body fat percentage data of different breeds of pets. It combines the pet's age, body length, body width, shoulder height, weight and electrical impedance data to jointly calculate the pet's body fat percentage, thereby assessing the pet's obesity status. It is highly accurate and easy to use.

[0010] In the above technical solution, preferably, the calculation formula for the pet body fat percentage calculation model R is as follows:

[0011] R = a1 + a2 × shoulder height + a3 × age + a4 × electrical impedance + a5 × body width + a6 × BMI;

[0012] Where a1 is a constant, and a2, a3, a4, a5 and a6 are linear fitting coefficients;

[0013] BMI = weight / body length 2 ;

[0014] The units for shoulder height and body width are cm, the unit for age is years, the unit for electrical impedance is Ω, the unit for weight is kg, and the unit for body length is m.

[0015] In the above technical solution, preferably, for pet dogs, the calculation formula for the pet body fat percentage calculation model R is as follows:

[0016] R = -18.087 - 0.267 × shoulder height + 0.712 × age + 0.008 × electrical impedance + 1.235 × body width + 0.172 × BMI.

[0017] In the above technical solution, preferably, it also includes an abdominal support device, which includes an abdominal support and a support rod for supporting the abdominal support;

[0018] The base has a socket in the center, and multiple pressure rods are provided in the socket. The base is provided with a micro switch that corresponds to each pressure rod.

[0019] The lower end face of the support rod is provided with multiple slots, each slot corresponding to the position of the pressure rod. Each slot has a first depth and a second depth, the first depth being greater than the height of the pressure rod and the second depth being less than the height of the pressure rod. For different models of abdominal support devices, the position and number of slots with the second depth on the support rod are different. When the support rod is inserted into the insertion hole, different slots press against different pressure rods, thereby closing the corresponding micro switch and forming a peeling signal for the corresponding model of abdominal support device.

[0020] In the above technical solution, preferably, a sleeve is inserted and fixed in the insertion hole, and an axially arranged strip-shaped protrusion is provided on the inner wall of the sleeve. A limiting groove is provided on the tube wall of the support rod, and the limiting groove is adapted to the strip-shaped protrusion.

[0021] In the above technical solution, preferably, the body fat percentage calculation module is located inside the body fat scale.

[0022] In the above technical solution, preferably, the body fat percentage calculation module is set on the host, and the transmission module on the base transmits the body shape data and the impedance data obtained by the acquisition device to the host.

[0023] In the above technical solution, preferably, four metal plates are provided on the top surface of the base, the four metal plates are arranged in a grid pattern, and the metal plates constitute the detection electrodes for measuring bioelectrical impedance.

[0024] In the above technical solution, preferably, the two metal plates on the left and right or front and back are short-circuited to form two detection electrodes.

[0025] As can be seen from the above technical solution, the pet body fat scale provided by this utility model solves the problem of low accuracy in assessing pet obesity in existing technologies. Compared with existing technologies, this utility model has the following beneficial effects:

[0026] A pet body fat percentage calculation model was constructed using multiple sets of body shape data, electrical impedance data, and body fat percentage data from different pet breeds. This calculation model combines the pet's age, body length, body width, shoulder height, weight, and electrical impedance data. The pet body fat percentage calculated using this model is fast, accurate, and easy to use, thus assessing the pet's obesity status. Attached Figure Description

[0044] Body fat analysis of pets can help assess their obesity status, providing a comprehensive understanding of their health, preventing diseases, and optimizing their reproductive and athletic performance. For example, it can help determine if a pet is overweight or obese, preventing related diseases; detect metabolic problems such as diabetes and fatty liver early, and develop personalized diet and exercise plans for the pet accordingly.

[0045] This application provides a pet body fat scale that uses multiple sets of body shape data, electrical impedance data, and body fat percentage data from different pet breeds to construct a pet body fat percentage calculation model. It combines the pet's age, body length, body width, shoulder height, weight, and electrical impedance data to calculate the pet's body fat percentage, thereby assessing the pet's obesity status. It is highly accurate and easy to use.

[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0047] To provide a clearer explanation and description of the technical solution and implementation of this utility model, several preferred specific embodiments for implementing the technical solution of this utility model are introduced below.

[0048] It should be noted that the directional terms such as "inner" and "outer", "front" and "back" and "left" and "right" in this article are based on the product's usage status. Obviously, the use of these directional terms does not limit the scope of protection of this solution.

[0049] like Figure 1 , Figure 2 As shown, this utility model provides a pet body fat scale, including a body fat scale 100, a data acquisition device, and a body fat percentage calculation module. The body fat percentage calculation module includes a pet body fat percentage calculation model, which is constructed using multiple sets of body shape data, electrical impedance data, and body fat percentage data from different pet breeds. The data acquisition device is used to collect the pet's characteristic data, body shape data, and electrical impedance data.

[0050] The pet's characteristics include pet ID, breed, and age, which can be entered via an input device.

[0051] Pet body size data, including body length, width, shoulder height, and weight, can be entered via an input device. Alternatively, it can be obtained by setting up a 3D measurement device and a weight measurement device on a body fat scale.

[0052] The pet's electrical impedance data can be obtained by measuring electrodes set on the body fat scale 100.

[0053] Specifically, the formula for calculating R in the pet body fat percentage calculation model is as follows:

[0054] R = a1 + a2 × shoulder height + a3 × age + a4 × electrical impedance + a5 × body width + a6 × BMI;

[0055] Where a1 is a constant, and a2, a3, a4, a5 and a6 are linear fitting coefficients;

[0056] BMI = weight (kg) / body length (m) 2 BMI (Body Mass Index) is the body mass index of a pet.

[0057] The units for shoulder height and body width are cm, the unit for age is years, the unit for electrical impedance is Ω, the unit for weight is kg, and the unit for body length is m.

[0058] The larger the amount of data collected, the more accurate the parameter values ​​of constant a1 and fitting coefficients a2, a3, a4, a5, and a6, and the higher the accuracy of the pet body fat percentage calculation model R.

[0059] Based on multiple sets of experimental data from pet dogs, the calculation formula for the body fat percentage calculation model R of pet dogs is as follows:

[0060] R = -18.087 - 0.267 × shoulder height + 0.712 × age + 0.008 × electrical impedance + 1.235 × body width + 0.172 × BMI.

[0061] In this invention, the body fat percentage calculation module can be installed on the body fat scale 100, on the host 200, or in the cloud. The specific installation method can be set according to the usage scenario. For example, if the body fat percentage calculation module is installed on the host 200, the transmission module on the base 10 transmits the pet's body shape data and electrical impedance data obtained by the acquisition device to the host 200, calculates the pet's body fat percentage, and displays it on the host 200.

[0062] The body fat scale 100 includes a base 10 and a pet three-dimensional measurement device, a bioelectrical impedance measurement electrode, and a weight measurement device disposed on the base 10. The pet three-dimensional measurement device is used to measure the pet's body width, body length, and shoulder height. The bioelectrical impedance measurement electrode is used to measure the pet's bioelectrical impedance. The weight measurement device is used to measure the pet's weight.

[0063] The pet 3D measurement device includes two body width measuring rulers 21, two body length measuring rulers 22, and one shoulder height measuring ruler 23. The body width measuring rulers 21, body length measuring rulers 22, and shoulder height measuring rulers 23 are made of soft materials to ensure the safety of the pet during measurement.

[0064] Specifically, the top surface of the base 10 has a longitudinal groove 11 and a transverse groove 12 arranged perpendicularly to each other, intersecting at the center of the base 10. Four metal plates are provided on the top surface of the base 10, arranged in a grid pattern relative to the longitudinal and transverse grooves. These metal plates constitute the detection electrodes for bioelectrical impedance measurement. In one embodiment, two metal plates, either side-by-side or front-back, are short-circuited to form two detection electrodes (positive and negative), which not only simplifies the design but also improves the accuracy of the measurement results.

[0065] Two body width measuring rulers 21 are respectively set in the longitudinal slide groove 11. The longitudinal slide groove 11 is equipped with a longitudinal slider. The longitudinal slider and the longitudinal slide groove 11 constitute a longitudinal displacement measuring device. The lower end of the body width measuring ruler 21 is rotatably set on the longitudinal slider. The longitudinal slider can move along the length direction of the longitudinal slide groove 11 to measure the body width of the pet.

[0066] Two body length measuring rulers 22 are respectively set in the transverse slide groove 12. A transverse slider is provided in the transverse slide groove 12. The transverse slider and the transverse slide groove 12 constitute a longitudinal displacement measuring device. The lower end of the body length measuring ruler 22 is rotatably set on the transverse slider. The transverse slider can move along the length direction of the transverse slide groove 12 to measure the body length of the pet.

[0067] When in use, the body width measuring ruler 21 and body length measuring ruler 22 can be rotated upwards and set perpendicular to the top surface of the base 10. At the same time, they can be moved along the longitudinal slide 11 and the transverse slide 12 respectively, and abut against the left and right sides and front and back sides of the pet, so as to measure the pet's body width and body length.

[0068] When not in use, the width measuring ruler 21 and length measuring ruler 22 can be rotated downwards to a horizontal position for concealment, i.e., hidden in the base, reducing space occupation and making them easy to store and move.

[0069] The shoulder height measuring ruler 23 includes a vertical rod 231 and a horizontal rod 232 set on the vertical rod 231. The horizontal rod 232 is slidably connected to the vertical groove on the inner side of the vertical rod 231 through a vertical slider. The vertical slider and the vertical groove constitute a vertical displacement measuring device. Thus, the horizontal rod 232 can be moved up and down along the vertical rod 231 and placed against the pet's shoulder to measure the pet's shoulder height.

[0070] In this design, when not in use, the width measuring ruler 21, length measuring ruler 22, and shoulder height measuring ruler 23 can all rotate downwards and be hidden in the base 10, thus facilitating storage and transportation. Figure 3 As shown.

[0071] exist Figure 4 In one usage scenario shown, the body fat scale 100 is connected to the host 200 via wired or wireless means. The body fat percentage calculation module is integrated into the pet body fat measurement app, which is installed on a tablet or smart TV. After receiving the measurement data from the body fat scale 100, the app uses the body fat percentage calculation module to calculate the current body fat percentage of the pet and displays it on the display interface.

[0072] Each test result and data can be stored on the server. Users can log in to the server with a username and password and query the test results and history of the pet by the pet ID.

[0073] An RFID reader can be installed on the body fat scale 100 or the main unit 200 to identify and obtain the pet's characteristic data by reading the pet's tag, or biochip technology can be used for identification and reading.

[0074] When performing bioelectrical impedance measurements on pets, the standard requires the pet to stand on four metal plates on a base with each of its four paws on top. However, in practice, pets often move around or even lie down on the base, leading to inaccurate measurements or even making it impossible to obtain the pet's bioelectrical impedance. To avoid this problem, this application provides a pluggable and detachable belly support device 40 on the base 10 to restrict the pet's movement or lying down.

[0075] like Figure 5 , Figure 6 , Figure 7 As shown, the abdominal support device 40 includes an abdominal support 41 and a support rod 42. The abdominal support 41 is fixed to the upper end of the support rod 42, and the support rod 42 is used to support the abdominal support 41.

[0076] The base 10 has a socket 15 at its center. Multiple pressure rods 16 are arranged in the socket 15 along the circumferential direction. The base 10 has a micro switch corresponding to each pressure rod. The pressure rod 16 is slidably arranged up and down and is opposite to the contact end of the micro switch. The corresponding micro switch can be opened or closed by moving the pressure rod 16 up and down.

[0077] A sleeve 17 is inserted and fixed inside the insertion hole 15. An axially arranged strip-shaped protrusion 171 is provided on the inner wall of the sleeve 17. A limiting groove 421 is provided on the tube wall of the support rod 42. The limiting groove 421 is adapted to the strip-shaped protrusion 171. The support rod 42 is inserted into the sleeve 17.

[0078] In this application, the support rod 42 adopts a circular tube structure and is adapted to the inner diameter of the sleeve 17. Multiple slots 422 are provided on the lower end surface of the tube wall of the support rod 42 along the circumferential direction. The position of each slot corresponds to the position of the pressure rod 16, and each slot has a first depth and a second depth. The first depth is greater than the height of the pressure rod 16, and the second depth is less than the height of the pressure rod 16, which is used to press down and close the corresponding micro switch.

[0079] Different models of abdominal support devices have different positions and numbers of slots with a second depth on the support rod 42. When the limiting groove 421 and the strip-shaped protrusion 171 are inserted and positioned, different slots press against different pressure rods, thereby closing different microswitches. Therefore, based on the combination of different microswitch closing states, the corresponding model of the abdominal support device can be determined. The weight of different models of abdominal support devices can be pre-input into the body fat percentage calculation module, so that when measuring the pet's weight, the skin can be removed for different models of abdominal support devices to obtain the pet's actual weight.

[0080] Figure 8 This is a schematic diagram illustrating the application of the abdominal support device.

[0081] The identification method of the abdominal support device will be described in detail below through an embodiment.

[0082] In this embodiment, the base 10 is provided with three micro switches A, B and C. The support rod 42 of the first type of abdominal support device has slots corresponding to the two micro switches A and B. The depth of the slots is less than the height of the pressure rod 16. When the first type of abdominal support device is inserted, micro switches A and B are closed and micro switch C is opened, generating signal 110.

[0083] The support rod 42 of the second-type abdominal support device has slots corresponding to two microswitches A and C. The depth of these slots is less than the height of the pressure rod 16. When the second-type abdominal support device is inserted, microswitches A and C close, microswitches B open, and signal 101 is generated.

[0084] The support rod 42 of the third-type abdominal support device has slots corresponding to the two microswitches B and C. The depth of these slots is less than the height of the pressure rod 16. When the third-type abdominal support device is inserted, microswitches B and C close, microswitches A open, and signal 011 is generated.

[0085] Therefore, when the three different models of abdominal support devices are inserted, the states of each microswitch and the corresponding abdominal support signals generated are as follows:

[0086] Abdominal support device model micro switch A micro switch B micro switch C Abdominal support signal First closure closure disconnect 110 second closure disconnect closure 101 third disconnect closure closure 011

[0087] The corresponding belly support device model can be obtained based on the received belly support signal (110, 101 or 011), and then the weight of the currently used belly support device can be obtained so that the weight of the belly support device can be removed when measuring the pet's weight to obtain the pet's actual weight.

[0088] The above embodiments are merely illustrative examples. Three, five, or more microswitches can be set according to actual needs to adapt to more models of abdominal support devices.

[0089] In addition, the support bar can be a pull-out lifting bar to accommodate pets of different heights.

[0090] The abdominal support device is made of insulating material to ensure the accuracy of bioelectrical impedance data during measurement.

[0091] Based on the above description of specific embodiments, the pet body fat scale provided by the utility model has the following advantages compared with the prior art:

[0092] First, a pet body fat percentage calculation model is constructed using multiple sets of body shape data, electrical impedance data, and body fat percentage data from different pet breeds. Based on the current pet's body shape data and electrical impedance data, the pet body fat percentage is automatically calculated using the pet body fat percentage calculation model. This pet body fat percentage combines the pet's age, body length, body width, shoulder height, weight, and electrical impedance data to assess the pet's obesity status. It is highly accurate and easy to use.

[0093] Secondly, the base is equipped with a pluggable and detachable belly support device, which can restrict the pet from moving or lying down during body fat percentage measurement, and can accurately measure the pet's bioelectrical impedance, thereby improving the accuracy of body fat percentage measurement results.

[0094] Third, the base has a central insertion hole with multiple pressure rods inside. The base also contains microswitches corresponding to each pressure rod. The lower end of the support rod of the abdominal support device has multiple slots, each with a first depth and a second depth. Different models of abdominal support devices have different positions and numbers of slots with the second depth on the support rod. When the support rod is inserted into the insertion hole, different slots press against different pressure rods, thus closing different microswitches and generating a peeling signal for the corresponding model of the abdominal support device. This allows for automatic identification of different models of abdominal support devices and automatic peeling, resulting in high accuracy and ease of use.

[0095] Finally, it should be noted that the terms "comprising," "including," or any other variations thereof as used herein are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising a…" does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0096] This utility model is not limited to the above-described preferred embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
