[0032] The specific embodiments described below are intended to help those skilled in the art understand this embodiment, but this embodiment is not limited to the specific embodiments described below.

[0033] Reference Figure 1 An exemplary embodiment of this disclosure provides an electronic weighing device, which includes:

[0034] The scale body includes a body 13, a display screen 11, a probe, and a support rod 132 that supports the display screen 11 and the probe above the body 13;

[0035] The perforated plate 2 is fixed above the tray 15 and forms a space between it and the tray 15 for accommodating impurities or sewage.

[0036] The tray 15 is fixed on the body 13. The tray 15 is located below the perforated plate 2 and has a support body 3 for supporting the perforated plate 2. The support body 3 includes a hollow sleeve 32 with an open top, a piston 31 coaxially inserted with the sleeve 32, and an elastic element 33 fixed inside the support body 3 to prevent the piston 31 from entering the support body 3. The top of the piston 31 extends from the top surface of the perforated plate 2 to the top of the perforated plate 2, and the sleeve 32 abuts against the perforated plate 2.

[0037] For example, refer to Figure 1 and Figure 2The body 13 includes a base 131 for accommodating electrical components and a support rod 132 fixed to one side of the base 131. The support rod 132 is vertical and extends above the top surface of the body 13. The body 13 is fixed with a metal flexible tube bracket 112 for fixing the probe. One end of the metal flexible tube bracket 112 is fixed to the side wall of the support rod 132, and the other end extends upward to the body 13 and is fixedly connected to the probe. The metal flexible tube bracket 112 is the bent tube used in the lazy bracket 112 in the prior art. The metal flexible tube bracket 112 can make the probe stay stably in the current position and maintain the current posture, which is suitable for different working conditions.

[0038] The display screen 11 is hinged to the body 13. The display screen 11 has a display posture with the display interface facing the perforated plate 2, and a transport posture with the display interface facing the perforated plate 2. Specifically, the display screen 11 includes a screen 111 and a bracket 112 fixedly connected to the screen 111. The bottom end of the bracket 112 is hinged to the top end of the support rod 132, and the rotation axis of the bracket 112 is horizontally set. The hinge side of the bracket 112 is located on the side of the support rod 132 directly opposite the base 131. When the bracket 112 rotates, it can rotate the screen 111, which was originally facing the top of the base 131, to face the base 131, thereby reducing the possibility of the screen 111 breaking under pressure during transportation. The body 13 is fixed with a support bolt 14 for abutting against the display screen 11 and preventing the display screen 11 from changing from the display posture to the transport posture. That is, the bottom end of the bracket 112 facing away from the screen 111 and the top end of the support rod 132 facing away from the base 131 both have outward protruding solid structures, such as block platforms. When the bracket 112 rotates to the top of the support rod 132, the bracket 112 and the support rod 132 form a long straight structure. The support bolt 14 is threaded to the aforementioned outward protruding structures of the bracket 112 and the support rod 132. The support bolt 14 connects the two protruding structures at the same time, thereby preventing the bracket 112 from rotating relative to the support rod 132, so that the screen 111 can be maintained in the current posture.

[0039] Reference Figure 3 and Figure 4The perforated plate 2 has a horizontal placement on the machine body 13 for use, and a cleaning posture where it is rotated to an angle with the machine body 13. Specifically, the tray 15 is fixed with C-shaped clips 23, which are fixed to the side wall of the tray 15, with the open end of the C-shaped clips 23 facing away from the tray 15. There are two C-shaped clips 23, located at both ends of the same side wall of the tray 15. The side wall of the perforated plate 2 is fixed with columnar locking pins 22 that are compatible with the C-shaped clips 23. The columnar locking pins 22 and C-shaped clips 23 are correspondingly located at both ends of the same side wall of the perforated plate 2. The columnar locking pins 22 are used to open the opening of the C-shaped clips 23. The mesh plate 2 is inserted into and hinged to the C-type buckle 23. When the mesh plate 2 is installed on the tray 15, the two columnar pins 22 are aligned with the two C-type buckles 23. By pressing the mesh plate 2 against the tray 15, the opening of the C-type buckle 23 is expanded, allowing the columnar pins 22 to enter the interior of the C-type buckle 23. The C-type buckle 23 can be made of polyethylene. The toughness of the polyethylene material allows the C-type buckle 23 to allow the columnar pins 22 to enter its interior and provides a limiting effect on the columnar pins 22, reducing the possibility of the columnar pins 22 disengaging from the interior of the C-type buckle 23 when the mesh plate 2 is rotated.

[0040] Reference Figure 4 and Figure 5 The side plate 21 has an upright posture extending from the top of the perforated plate 2, and a folded posture located below the top surface of the perforated plate 2. Specifically, the top surface of the perforated plate 2 is rectangular, the side wall of the tray 15 is rectangular, and the top edge of the perforated plate 2 and the side wall edge of the tray 15 both have insertion slots 4. The insertion slots 4 are arranged in pairs at both ends of the top edge of the perforated plate 2 and at both ends of the side wall of the tray 15. The side plate 21 has insertion rods 211 that are adapted to the insertion slots 4. Each side plate 21 has two insertion rods 211, and the two insertion rods 211 are located at both ends of the bottom surface of the side plate 21 in the upright posture. When the side panel 21 needs to be in an upright position, the two insert rods 211 are respectively inserted into the slots 4 on the top edge of the perforated plate 2, thus fixing the side panel 21 to the perforated plate 2. Similarly, when the side panel 21 needs to be in a folded position, simply pull out the side panel 21 and insert the two insert rods 211 of the side panel 21 into the two slots 4 on the side wall of the tray 15. It is worth mentioning that, in order to ensure that the top surface of the side panel 21 in the folded position is not higher than the top surface of the perforated plate 2, this can be achieved by changing the position of the slots 4 and changing the thickness of the side panel 21.

[0041] Reference Figure 5 and 6The tray 15 is inclined internally, and its internal outline is cuboid. The bottom surface of the tray 15 has a sloping portion 153, which extends from one inner sidewall to the bottom of another inner sidewall opposite to the first, thus creating an uneven bottom surface. The tray 15 has a water outlet 151 with a plug 152. The water outlet 151 is located on the lower side of the bottom surface, and its bottom edge is flush with the bottommost side of the bottom surface. The water outlet 151 horizontally penetrates this sidewall of the tray 15. The plug 152 is detachably connected to the water outlet 151 and protrudes from it. By removing the plug 152, water inside the tray 15 can flow out through the water outlet 151. The bottom side of the inclined tray 15 is detachably connected to a sealing door 154. The side wall of the tray 15 with the outlet 151 forms the sealing door 154. The installation method of the sealing door 154 is a conventional and mature existing technology. It can be sealed 152 in various ways, such as hinge, plug, or even through interference fit. The sealing strip added to the edge of the sealing door 154 to prevent the liquid in the tray 15 from leaking from the edge of the sealing door 154 is also a mature and conventional existing technology, which does not need to be elaborated here.

[0042] Reference Figure 2 and 7Multiple sleeves 32 are arranged in an array inside the tray 15. The sleeves 32 are fixed to the inside of the tray 15 in a vertical position with their openings facing upwards. For example, the bottom end of the sleeve 32 is fixed to the solid structure of the bottom surface inside the tray 15. Since the bottom surface inside the tray 15 is inclined, in order to ensure that the sleeve 32 can maintain a vertical position, the bottom end of the sleeve 32 can be inserted into the solid structure below the bottom surface of the tray 15. This structure can be achieved by conventional processes such as machining and injection molding. Alternatively, the length of the sleeve 32 can be designed to fit the tray 15 with its inclined bottom surface. The sleeves 32 can be installed inside the tray 15 by installing sleeves 32 of different lengths in different positions. The elastic element 33 includes a spring coaxial with the sleeve 32 and located inside the sleeve 32. The bottom end of the spring, as the elastic element 33, is fixedly connected to the bottom surface inside the sleeve 32, and the top end is fixedly connected to the bottom end of the piston 31. The outer diameter of the piston 31 is adapted to the inner diameter of the sleeve 32. When the spring is in its natural state, the spring pushes the top end of the piston 31 out of the sleeve 32, while the bottom end of the piston 31 remains inside the sleeve 32. In addition to its own holes for filtering fine impurities and liquids, the perforated plate 2 also has a through hole 5 that penetrates the perforated plate 2 vertically. The size of the through hole 5 is adapted to the outer diameter of the piston 31. The top end of the piston 31 extends through the through hole 5 to the top surface of the perforated plate 2. When the perforated plate 2 is placed on the tray 15 in a usage posture, the bottom surface of the perforated plate 2 abuts against the top end face of the sleeve 32. The sleeve 32 provides support to the perforated plate 2, reducing the possibility of the perforated plate 2 collapsing.

[0043] It should be noted that the interference of the piston 31 on the rotation of the perforated plate 2 can be eliminated by enlarging the size of the through holes 5 in different areas, so that the perforated plate 2 can rotate freely. Alternatively, the perforated plate 2 can be disassembled and cleaned by removing the C-type buckle 23 and the columnar pin 22 while keeping the perforated plate 2 horizontal.

[0044] In this embodiment, the perforated plate 2, which is separate from the tray 15, provides the stroke for the piston 31 to rise and fall. The sleeve 32 supports the perforated plate 2, thereby weighing the object placed on the perforated plate 2. The piston 31, which extends from the top of the perforated plate 2, can be pressed down when the object is placed in the weighing area, while the piston 31 at the edge of the object is not subjected to vertical downward pressure and maintains the posture of extending from the top of the perforated plate 2, thereby providing a lateral obstruction effect on the object and reducing the possibility of the object to be weighed moving laterally or even rolling.
