As shown in fig. 1 and 2, an embodiment of the present invention provides an electronic scale for infants, which includes a base 1 and a supporting plate 2, wherein the supporting plate 2 is disposed above the base 1.

The base 1 comprises a first supporting part 11 and a second supporting part 12 which are symmetrically arranged, and the first supporting part 11 and the second supporting part 12 are fixedly connected through two parallel connecting frames 13. The connecting frame 13 is a long rod-shaped structure, one end of the connecting frame 13 is connected with the end part of the first supporting part 11, and the other end of the connecting frame 13 is connected with the end part of the second supporting part 12, so that the first supporting part 11, the second supporting part 12 and the two connecting frames 13 enclose a rectangular area.

The first supporting portion 11 is provided with a first mounting groove 111 on an upper surface thereof facing the pallet 2, and the second supporting portion 12 is provided with a second mounting groove 121 on an upper surface thereof facing the pallet 2. The overlooking shapes of the first installation groove 111 and the second installation groove 121 are both trapezoidal, and the longer side of the trapezoid is closer to the center of the base 1 than the shorter side of the trapezoid, so that the occupied space of the base 1 can be reduced as much as possible.

A weighing sensor 3 is respectively arranged in the first mounting groove 111 and the second mounting groove 121, and the bottom of the supporting plate 2 is connected with the weighing sensor 3. When a heavy object or baby is placed on the pallet 2, the load cell 3 may sense the weight of the object or baby on the pallet 2. For the year thing on the guarantee layer board 2 is placed stably, the border of layer board 2 is equipped with the round bounding wall that upwards extends, reduces the risk that carries the thing landing from layer board 2.

Further, the base 1 may be assembled to other medical equipment, so that the infant electronic scale of the present embodiment is conveniently integrated to other medical equipment.

Illustratively, infant incubators generally include a support frame and a carrier disposed on the support frame, on which an infant formula is disposed. The infant carrier is typically housed on a carrier to form a space for receiving an infant. In order to integrate the infant electronic scale of the embodiment on the infant incubator, the base 1 is only required to be fixedly connected with the upper surface of the carrying platform, the connection mode can be screw connection, welding or riveting, and the like, and more convenient detachable connection and the like can also be adopted. Then, the supporting plate 2 is provided with auxiliary elements such as a cushion and the like which are convenient for a baby to lie, and the baby box body is covered on the upper part of the supporting plate 2. Finally, the detection signal of the weighing cell 3 can be connected to a display or control device of the infant incubator. Since the first support part 11 and the second support part 12 are connected only by the connection frame 13, there is a large space for relief between the first support part 11 and the second support part 12, and other accessories of the infant incubator, such as electric components or parts, can be accommodated.

The above is only an example, and the infant electronic scale of the present embodiment may be actually connected to other infant medical equipment, such as a jaundice treatment apparatus, a transport incubator, and the like. It can be seen that the infant electronic scale of the present embodiment has good applicability in combination with other medical equipment.

Of course, the infant electronic scale of the present embodiment may also be used alone as an infant weighing apparatus.

On the other hand, as can be seen from the above description, the electronic scale for babies of the present embodiment has a simple structure and is convenient to assemble. During assembly, only the load cell 3 needs to be mounted in the first mounting groove 111 and the second mounting groove 112, and then the support plate 2 is mounted on the top of the load cell 3.
