[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0032] The accompanying drawings of the embodiments of this utility model provide a coordinate system XYZ, where the positive direction of the X-axis represents the left and the negative direction of the X-axis represents the right, the positive direction of the Y-axis represents the front and the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top and the negative direction of the Z-axis represents the bottom.

[0033] This utility model embodiment provides an electronic scale, combined with Figure 1 and Figure 2 As shown, the weighing system includes a weighing body 1 and a weighing pan 2 mounted on the weighing body 1. The weighing pan 2 includes a pan bottom 21 and a pouring nozzle 22, a positioning seat 23, and elastic guards 24 disposed on the pan bottom 21. The pouring nozzle 22 and the positioning seat 23 are spaced apart and connected by two elastic guards 24 to form a closed loop structure. The connection points of the pouring nozzle 22, the positioning seat 23, and the elastic guards 24 with the pan bottom are all chamfered for smooth transition. The pouring nozzle 22 and the two elastic guards 24 form the pouring port of the weighing pan 2. The opening spacing in the middle section of the pouring port is adjusted by the elastic deformation of the elastic guards 24.

[0034] Combination Figure 3 and Figure 4The closed-loop structure can be a circular ring, a square ring, or some irregularly shaped ring. In this embodiment, the closed-loop structure is square, and the Y-axis length on the rear side is shorter than that on the front side. This allows the weighing pan 2 to be better held by the user and to apply force to the elastic retaining edge 24 to achieve elastic deformation. Furthermore, to better understand the "opening distance of the middle section of the pouring spout," this embodiment uses "L" and "L'" in the accompanying drawings. L represents the opening distance in the unforced state, and L' represents the opening distance in the forceped state. A larger L' indicates a smaller force, and vice versa. Therefore, this embodiment adjusts the opening distance of the middle section of the pouring spout by applying appropriate pressure as needed, allowing the pouring spout to accommodate containers with different opening sizes for orderly material pouring, reducing material spillage from both sides of the spout, and minimizing material loss.

[0035] Optionally, combined Figure 5 The height of the pouring nozzle 22 (length in the Z-axis direction) is lower than the height of the elastic guard 24. That is, the closed-loop structure has a downward-sloping arc surface at the pouring nozzle 22. This not only helps the pouring nozzle 22 to better insert into some containers with smaller openings (such as teapots, coffee grinders, etc.), but also helps to work with the elastic guard 24 to ensure that the material falls into the container effectively, reducing the amount of material remaining in the weighing pan 2.

[0036] Optionally, combined Figure 3 and Figure 4 The thickness of the side of the elastic guard 24 connected to the pouring nozzle 22 is less than the thickness of the side of the elastic guard 24 connected to the positioning seat 23. During pouring, the tilt of the weighing pan 2 causes material to accumulate at the pouring nozzle 22. When force is applied to the elastic guard 24, the side of the elastic guard 24 connected to the pouring nozzle 22 first undergoes elastic deformation towards the inside of the weighing pan 2, providing upward support for the material accumulated on both sides of the pouring nozzle 22. This, to a certain extent, slows down the falling speed of the material, achieving orderly conveying. Furthermore, the elastic guard 24 in this embodiment uses one of the following: food-grade silicone, rubber, or elastic plastic. Silicone, rubber, and flexible elastic plastics such as TPE / TPU all have good elastic deformation and recovery capabilities, and good plasticity, which helps simplify the structure of the electronic scale and facilitates mass production and application.

[0037] Optionally, combined Figure 2 and Figure 3The positioning seat 23 includes two positioning flanges 231 and a positioning cover 232 connected between the two positioning flanges 231. The side of the positioning flange 231 away from the positioning cover 232 is connected to the elastic flange 24. Since the elastic flange 24 has elastic deformation capability, in this embodiment, the positioning flange 231 and the discharge nozzle 22 are used to fix the two ends of the elastic flange 24 respectively, thereby maintaining the integrity of the closed-loop structure to hold more material. The discharge port is maintained in a V-shape by the two positioning flanges 231, and the material can be conveyed inclined downward along the two guide surfaces within the V-shape structure.

[0038] Optionally, the positioning cover 232 protrudes towards the side near the pouring nozzle 22 to divide the weighing pan 2 into left and right sides. As a result, the material contained in the weighing pan 2 will be divided into two at the positioning cover 232. During pouring, the material in the left and right parts can tilt downwards along the guide surface of their respective V-shaped structures and finally be conveyed to the pouring nozzle 22 to complete the pouring action, further promoting the orderly pouring of materials.

[0039] Optionally, combined Figure 6 and Figure 7 The scale body 1 includes a base 11, a weighing display mechanism 12, and a cover plate 13. The weighing display mechanism 12 is installed inside the base 11, and the cover plate 13 is installed at the bottom of the weighing display mechanism 12 and supports the base 11, preventing the base 11 from being suspended when the scale is on a work surface, thus achieving the weighing function. To further increase the scale's anti-slip properties, this embodiment can also add a pad 14 to the bottom of the cover plate 13. The pad 14 can be connected to the cover plate 13 in various ways, including but not limited to adhesive bonding, snap-fit ​​fixing, and fastener fixing. This embodiment specifically shows the adhesive bonding method.

[0040] The base 11 and the weighing pan 2 can be separately manufactured and then assembled. The base 11 can be made of materials such as hard plastic, stainless steel, or ceramic, while the weighing pan 2 is made of materials such as silicone, rubber, or elastic plastic disclosed above. During assembly, the base 11 provides support for the weighing pan 2, and the elasticity of the weighing pan 2 is well stretched and covered on the outside of the base 11. Alternatively, the base 11 can be manufactured first, and then the base 11 can be placed into an injection mold to inject the material used to mold the weighing pan 2, so that the base 11 and the weighing pan 2 are combined into one piece.

[0041] The base 11 has a first protruding edge 111 and a second protruding edge 112. (Combined) Figure 8 and Figure 9The bottom of the discharge nozzle 22 is provided with a first groove 221 for the insertion of the first protruding edge 111, and the bottom of the positioning stop 231 is provided with a second groove 2311 for the insertion of the second protruding edge 112. Additionally, the base 11 has a protruding shell 113 on the side away from the first protruding edge 111, and a positioning cover 232 is placed over the outside of the protruding shell 113 to protect it. The lower side of the protruding shell 113 is connected to the bottom of the base 11, creating an opening at the bottom of the base 11. A cover plate 13 is provided at this opening, through which the weighing digital display mechanism 12 is inserted into the base 11.

[0042] Based on this, the base 11 is tightly connected with the pouring nozzle 22, the positioning stop 231 and the positioning cover 232 respectively through the setting of the first protruding edge 111, the second protruding edge 112 and the protruding shell 113, so that the base 11 and the weighing pan 2 are firmly integrated into one body. This not only increases the structural stability of the electronic scale and helps to weigh materials better, but also makes it convenient to clean and store the electronic scale after use.

[0043] Optionally, combined Figure 6 and Figure 7 The weighing digital display mechanism 12 includes a pressure sensing module 121, a digital display module 122, and a battery module 123. The pressure sensing module 121 includes a base plate 1211 and a pressure sensor 1212. The base plate 1211 is fixedly mounted on the bottom of a base 11 using screws or other fasteners. The bottom of the base 11 has a slot 114 for the pressure sensing module 121 to be inserted. The pressure sensor 1212 is fixedly mounted on the base plate 1211 to detect the weight of the material being tested. A cover plate 13 is fixedly connected to the bottom of the pressure sensor 1212 using screws or other fasteners. When installing the pressure sensing module 121, first, the base plate 1211 is fixedly connected to the pressure sensor 1212. Then, the slot 114 is used for initial positioning of the base plate 1211. Next, screws or other fasteners are used to fix the bottom of the base plate 1211 to the base 11 at its four corners. Finally, the cover plate 13 is fixedly connected to the bottom of the pressure sensor 1212 to lift the base 11. The digital display module 122 and the battery module 123 are installed inside the convex shell 113. The top of the positioning cover 232 has a through hole 2321 for the display screen 1221 of the digital display module 122 to be exposed. When weighing materials, the pressure sensor module 121 is used to detect the weight of the material to be measured and display it through the digital display module 122. The battery module 123 powers the pressure sensor and the digital display module 122.

[0044] The battery module 123 can also be configured as a rechargeable battery module, specifically including a charging circuit board 1231, a power charging port 1232 located on one side of the charging circuit board 1231, and a storage battery 1233 for storing electrical energy. The charging circuit board 1231 is connected to the digital display template 122, and the circuit board of the digital display template 122 and the charging circuit board 1231 of the battery module 123 can share a common substrate. The power charging port 1232 passes through the convex shell 113 and protrudes from one side of the positioning cover 232 to facilitate connection to an external power source. That is, the electrical energy from the external power source is transmitted to the charging circuit board 1231 through the power charging port 1232 and then stored in the storage battery 1233. It should be noted that the above-described weighing digital display mechanism 12 is intended to introduce the installation positions of the three major modules: the pressure sensing module 121, the digital display module 122, and the battery module 123, so as to facilitate a more compact structural arrangement between the various components of the electronic scale, which helps to reduce the overall size of the electronic scale and make it more compact and portable. However, its corresponding weighing principle is existing technology in the field of electronic scales, so it will not be described in detail.

[0045] In addition, the convex shell 113 also has sealing structures such as sealing protrusions 1131 around the display screen 1221 of the digital display module 122 and around the power charging port 1232 of the battery module 123, thereby increasing the waterproof performance of the electronic scale and reducing the difficulty of cleaning the electronic scale.

[0046] In summary, the electronic scale of this embodiment is well-suited for weighing materials such as tea leaves, coffee beans, coffee powder, and soybeans, which have relatively small weights and are inconvenient to transfer to other containers. It can adjust the opening spacing in the middle section of the pouring spout as needed to achieve orderly pouring of materials.
