[0026] It should be noted that the focus of the present application is the setting of the waterproof structure.

[0027] Specifically, the measuring part comprises a scale foot 21, a sensor 22, a display and a circuit board assembly, the bottom plate part 5 of the bottom shell 3 is provided with a scale foot hole 9, the lower end of the scale foot 21 protrudes from the scale foot hole 9, the upper end of the scale foot 21 is in contact with the bottom surface of the sensor 22, and the top end of the sensor 22 is in contact with the surface shell 4; the display and the circuit board assembly can be arranged on the surface shell 4, but are not limited thereto; since these components and their setting modes are common setting modes of the electronic scale structure in the field, they are not introduced as the focus content.

[0028] Specifically, the scale surface 1 has a certain bearing capacity and can bear the gravity of the object to be weighed, the scale surface 1 can be a glass panel or a metal panel, and the commonly used glass is tempered glass, but is not limited thereto; the bottom shell 3 and the surface shell 4 can be plastic materials, preferably ABS plastic; the present application does not arrange outwardly extending eaves on the surface shell 4 and the bottom shell 3, but the bottom plate part 5 and the peripheral part 6 of the bottom shell 3 surround a cavity, the cavity is used to accommodate the surface shell 4, the display and the circuit board assembly arranged on the surface shell 4, and the sensor 22 and the upper end of the scale foot 21; further, the surface shell 4 is assembled with the bottom plate part 5 of the bottom shell 3 through a threaded part, after assembly, the outer edge of the surface shell 4 and the peripheral part 6 form a glue groove 7; the four corners of the scale surface 1 can be attached to the surface shell 4 through double-sided foam tape, for determining the relative position of the scale surface 1 and the electronic scale body 2; the glue groove 7 is provided with sealing glue 8, the scale surface 1, the surface shell 4 and the bottom shell 3 are sealed and connected through the sealing glue 8, wherein the sealing glue can be silicone; thus, the display and the circuit board assembly and the sensor 22 can be covered, water or water vapor can be prevented from penetrating into the electronic scale from between the scale surface, the bottom shell and the surface shell, thereby the damage to the internal elements of the electronic scale can be prevented, the normal use of the electronic scale is ensured, and the waterproof structure is simplified.

[0029] It can be understood that in use, referring to the electronic scale in the prior art, the object is placed on the scale surface 1 of the electronic scale or a person stands on the scale surface 1 of the electronic scale, through the induction of the sensor 22 and the display window on the scale surface 1, the weight of the object or the person can be obtained.

[0030] Further, the electronic scale body 2 further comprises a TPE waterproof scale foot sleeve 10 formed at the scale foot hole 9 by secondary injection molding, and the TPE waterproof scale foot sleeve 10 covers the part of the scale foot protruding out of the scale foot hole 9. In the prior art, the scale foot and the scale foot hole are usually connected by a gap, and water vapor or water flow can easily enter the inside of the kitchen scale from the gap. In order to prevent water from entering the inside of the kitchen scale, the TPE waterproof scale foot sleeve 10 is formed at the scale foot hole 9 by secondary injection molding, the TPE waterproof scale foot sleeve 10 is integrated with the scale foot hole 9, and the TPE waterproof scale foot sleeve 10 covers the part of the scale foot 21 protruding out of the scale foot hole 9. Thus, water on the ground or other supporting surface or water vapor in the air can be prevented from penetrating into the inside of the electronic scale from the gap between the scale foot 21 and the scale foot hole 9, thereby preventing damage to the internal elements of the electronic scale and ensuring normal use of the electronic scale.

[0031] More specifically, as shown in Figure 7 the TPE waterproof scale foot sleeve 10 comprises a connecting part 15 at the upper end, a standing foot 16 at the lower end, and a diffusion part 17 arranged around the standing foot. The connecting part 15 is connected with the edge of the scale foot hole 9, and the standing foot 16 is arranged corresponding to the lower end surface of the scale foot 21. The cross section of the diffusion part 17 is corrugated, and the thickness of the diffusion part 17 is smaller than the thickness of the standing foot 16. When the scale foot 21 in the electronic scale bears a heavy object or human weight, the standing foot 16 is compressed, and the standing foot 16 and the diffusion part 17 are elastically deformed. Since the cross section of the diffusion part 17 is corrugated and the thickness of the diffusion part 17 is smaller than the thickness of the standing foot 16, the diffusion part 17 is more likely to deform. Therefore, the influence of the TPE waterproof scale foot sleeve 10 on the weighing accuracy of the electronic scale can be reduced.

[0032] Further, as shown in Figure 8 the bottom plate part 5 of the bottom shell 3 is provided with a battery compartment 11, and the waterproof electronic scale further comprises a compartment door 12 detachably connected with the battery compartment 11. A first groove 18 is arranged at the edge of the lower end of the battery compartment 11, a TPE waterproof sealing ring 13 is formed in the first groove 18 by secondary injection molding, a second groove 19 is arranged at the lower end of the TPE waterproof sealing ring 13, and a protrusion 20 is arranged at the upper end of the compartment door 12 and matched with the second groove 19. In this application, the TPE waterproof sealing ring 13 is integrally formed at the connecting part of the battery compartment 11 and the compartment door 12 by secondary injection molding, and is matched with the second groove 19 at the lower end of the TPE waterproof sealing ring 13 by the protrusion 20 at the upper end of the compartment door 12. When a threaded part or a buckle structure is used to fix the compartment door 12 on the battery compartment 11, the protrusion 20 extrudes the TPE waterproof sealing ring to deform, thereby achieving good sealing of the battery compartment 11 and the compartment door 12, effectively waterproofing the part of the battery compartment 11, and ensuring normal operation of the battery in the battery compartment 11.

[0033] Specifically, when the bottom shell 3 is ABS plastic, the TPE waterproof scale foot sleeve 10 is overmolded on the bottom shell 3 at a temperature of 220°C, and the TPE waterproof sealing ring 13 is overmolded in the first groove 18 at a temperature of 220°C.

[0034] It should be noted that, Figures 1-8 It is only a schematic diagram, although Figures 1-8 The electronic scale shown in the figure is square, but can also be other shapes, such as circular, or other suitable shapes.
