[0002] Infancy is the period when people are most vulnerable and need the most protection. People often invest huge amounts of energy in caring for and raising infants, and frequently monitor the infant's various physiological indicators to ensure their normal growth.

[0003] Among these physiological indicators, weight is a very important parameter. Since babies are very light, the weight of their clothes has a great impact on the measurement of their weight. Therefore, when measuring the weight of babies, it is usually measured naked to obtain the most accurate weight data.

[0004] However, due to the weak constitution of infants and their poor ability to resist cold, there is a risk of catching a cold when measuring naked at low room temperature. And if the temperature of the measuring plate that directly contacts the infant's skin is low during measurement, the infant will feel very uncomfortable, causing the infant to cry and affect the weight measurement. The existing method of setting a cushion on the measuring plate cannot solve this problem well. The cold cushion is only slightly better than the metal tray, but it cannot fundamentally solve the above problems. Summary of the invention

[0005] In view of this, it is necessary to provide a multifunctional scale to solve the technical problem in the prior art that when the room temperature is low, the baby is prone to catch a cold and cry when measuring weight naked, which affects the measurement.

[0017] Figure 3 It is a schematic diagram of the structure of the gas heating unit. DETAILED DESCRIPTION

[0018] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0019] See also Figures 1 to 3 The multifunctional scale comprises a base 1, a fan 2, a weighing sensor 3, a carrier plate 4, a hot water bag 5, a heating tube 6, a safety tube 7 and a length measuring plate 8. It can be used to measure the height and weight of a baby, and during the measurement process, a warm and comfortable environment is created for the baby to prevent the baby from catching a cold.

[0020] The cross section of the base 1 is U-shaped, so a baby groove 11 is formed in the middle of the base 1. The size of the baby groove 11 should be large enough to accommodate a flat baby. For example, the size of the baby groove can be 1 meter long, 0.5 meter wide, and 0.5 meter deep. It can also be adjusted according to actual needs, or multiple sizes can be designed for babies of different months.

[0021] A warm air cavity 12 is formed inside the base 1, and an air inlet 13 of the warm air cavity 12 is provided on the outer wall of the base 1, and an air outlet 14 of the warm air cavity 12 is provided on the inner wall of the baby tank 11. A fan 2 is provided in the warm air cavity 12, and the fan 2 drives air to flow from the air inlet 13 to the air outlet 14. Considering that the airflow in the warm air cavity 12 is smoother and more orderly, and the airflow distribution in the baby tank 11 is more uniform, in this embodiment, two warm air cavities 12 are provided, which are respectively provided on both sides of the central axis along the central axis of the base 1, and the air outlets 14 of the two warm air cavities 12 are respectively provided on the side walls of the two relatively long sides of the baby tank 11, and there are also multiple air outlets 14, which are evenly distributed along the side walls of the baby tank 11, so that the warm air blown out from the warm air cavity 12 can evenly fill the entire baby tank 11. In order to make the air flow more smoothly in the warm air cavity 12 , the warm air cavity 12 preferably adopts an arc-shaped design at the corner, so that the air can flow along the extension direction of the warm air cavity 12 .

[0022] The weighing sensor 3 is arranged on the bottom surface of the baby tank 11, and the measuring end of the weighing sensor 3 is vertically upward and connected to the carrier plate 4, and the hot water bag 5 is placed on the carrier plate 4. The hot water bag 5 is filled with a heat-conducting liquid. In this embodiment, the heat-conducting liquid is generally pure water; in other embodiments, a liquid with a higher viscosity, such as oil, can also be used.

[0023] When measuring the weight of a baby, it is only necessary to place the baby on the warm water bag 5, and the weighing sensor 3 can measure the weight of the baby. In order to display the weight of the baby more clearly and conveniently, a display screen 9 for displaying the weight value can be set on the outer surface of the base 1. A necessary processor (not shown) is set in the base 1 to connect with the weighing sensor 3 and the display screen 9. The data measured by the weighing sensor 3 is transmitted to the processor, and after being processed by the processor, it is transmitted to the display screen 9 for display, so that the staff who weighs the baby can read it conveniently. The use of a suitable processor and display screen, as well as the connection method with the weighing sensor 3 are all conventional technologies in the field of electronic scales, which are well known to technicians in the field of electronic scales, so they will not be repeated here.

[0024] The heating tube 6 is arranged through the warm air cavity 12 and the hot water bag 5 and is sealed with the hot water bag 5 to prevent the heat-conducting liquid in the hot water bag 5 from flowing out. The heating tube 6 is used to heat the air and heat-conducting liquid in the warm air cavity 12. The gas heating part is arranged in the warm air cavity 12, and the liquid heating part is arranged in the hot water bag 5. Two gas heating parts are arranged at both ends of the liquid heating part. The gas heating part is a mesh structure, such as Figure 3 As shown, a larger contact area is obtained, thereby quickly heating the air flowing in the warm air chamber 12. In this embodiment, the heating tube 6 can be an adjustable electric heating tube, and the heating amount of the heating tube 6 can be adjusted by adjusting the input current.

[0025] Preferably, since the baby's skin is very delicate, in order to avoid burns, a temperature sensor is provided in the warm air chamber 12. The temperature sensor is used to detect the temperature in the warm air chamber 12 and adjust the heating power of the heating tube 6 according to the temperature, so that the temperature of the warm air blown out of the air outlet 14 is maintained in the range of 37-38°C, so that the temperature in the baby tank 11 will not be overheated or overcooled, giving the baby a most comfortable temperature.

[0026] At the same time, the liquid heating unit heats the heat-conducting liquid in the hot water bag 5, so that the heat-conducting liquid also reaches a temperature range of 37-38°C, and the baby can feel warm and comfortable when placed on the hot water bag 5. In order to prevent the baby from being scalded by contact with the heating tube 6, a safety tube 7 is also provided in the hot water bag 5. The safety tube 7 is made of hard material and is sleeved on the heating tube 6 to prevent the baby from contacting with the heating tube 6.

[0027] The multifunctional scale also has the function of measuring the height of a baby. A scale line indicating the length is arranged on the upper surface of the base 1 along the direction of the baby groove 11, and a slide groove 15 is also arranged along the direction of the baby groove 11. The length measuring plate 8 can slide along the slide groove 15, and the length measuring plate 8 includes a gripping portion 81, a sliding portion 82 and a measuring portion 83 which are integrally formed and connected from top to bottom. The gripping portion 81 is provided with anti-slip grooves, and the sliding portion 82 is provided with a protrusion corresponding to the slide groove 15. Through the matching connection between the protrusion and the slide groove 15, the length measuring plate 8 can slide along the slide groove 15, and the measuring portion 83 extends into the baby groove 11. When measuring the height of a baby, the head or foot of the baby is pressed against one end of the baby groove 11, and then the length measuring plate 8 is slid so that the measuring portion 83 is pressed against the foot or head of the baby, and then the length shown on the scale line is read as the height of the baby.

[0028] When using the multifunctional scale, firstly connect the multifunctional scale to an external power source to power the fan 2 and the heating tube 6. When the heating tube 6 heats the heat-conducting liquid in the hot water bag 5 and the air in the warm air chamber 12 to a suitable temperature such as 37-38°C, and the fan 2 drives the warm air to flow and fill the baby tank 11, so that the temperature in the baby tank 11 is also 37-38°C, the preheating preparation work is completed and measurement can be performed.

[0029] During measurement, the baby is placed in the baby groove 11 and laid flat on the warm water bag 5. The weighing sensor 3 obtains the baby's weight information and displays it on the display screen 9, which the staff can record. Then the baby's head or foot is pressed against one end of the baby groove 11, and the length measuring plate 8 is slid so that the measuring part 83 is pressed against the baby's foot or head. The staff reads the length shown on the scale line as the baby's height and records it.

[0030] During the whole measuring process, the warm water bag 5 is in direct contact with the baby, and the warm air is filled around the baby, so that the baby is always in a warm environment and avoids catching a cold.

[0031] The implementation of the embodiment of the present invention has the following beneficial effects: the multifunctional scale has a heating tube running through the warm air cavity and the hot water bag, the heating tube can heat the heat-conducting liquid in the hot water bag and the hot air blown out by the heating fan, the hot air is blown into the baby cavity from the air outlet and fills the baby cavity, when weighing the baby, the baby is placed on the hot water bag in the baby cavity, the warm hot water bag and the baby cavity put the baby in a warm and comfortable environment, avoid catching a cold, and keep the baby calm, which is convenient for measuring the baby's weight.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
