[0001] This utility model relates to the field of weighing equipment technology, specifically to electronic scales. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] With the development of technology, shopping malls have adopted AI electronic scales to replace manual weighing and pricing of goods in order to reduce labor, improve merchandise handling efficiency, and lower operating costs. The use of AI electronic scales has made shopping more convenient for consumers and has been well-received. Existing self-service intelligent weighing equipment (electronic scales) is generally equipped with cameras that automatically identify the category of the items to be weighed by photographing them, thus achieving intelligent weighing.

[0004] However, current AI scales still have problems. After prolonged use, the weighing pan is prone to corrosion and rust, requiring regular disassembly, cleaning, maintenance, or replacement. Replacing the weighing pan on traditional AI scales is cumbersome and time-consuming. Furthermore, when weighing goods with high moisture content, moisture can easily enter the scale body through the connection between the weighing pan support and the scale body, damaging electrical components and affecting the lifespan of the AI ​​scale. Utility Model Content

The top of the locking plate has a second inclined surface that slides and presses against the first locking block.

[0016] Furthermore, a second washer is fixedly sleeved on the outer side of the operating rod, and a second spring is sleeved on the outer side of the operating rod. The two ends of the second spring are respectively connected to the ring wall of the second washer and the corresponding inner wall of the second positioning block.

[0017] Furthermore, the positioning hole has a semi-circular cross-section, and two guide plates are arranged opposite each other on the straight sidewall of the positioning hole, with a gap between the two guide plates for the first locking block to pass through; when the positioning rod is fully inserted into the positioning hole, the second locking block is locked in the gap between the two guide plates.

[0018] Furthermore, the top of the water receiving tray is surrounded by a downward sloping ramp, the bottom of the ramp is connected to the inlet of the drain hole, and a drain pipe connected to the outlet of the drain hole is installed at the bottom of the water receiving tray.

[0019] Furthermore, the scale body has a base plate at the bottom, on which a camera suspended above the scale pan is mounted by a bracket, and a display is also mounted on the bracket.

[0020] The beneficial effects of this utility model are reflected in:

[0021] The electronic scale of this utility model adds a water receiving tray to the original scale body to drain water that remains on the scale pan in a timely manner, preventing water from entering the scale body and affecting its service life. Furthermore, through the added positioning block, positioning rod and corresponding locking components, the disassembly and assembly of the scale pan and water receiving tray can be carried out conveniently and efficiently, thereby quickly completing the cleaning, maintenance or replacement of the scale pan and water receiving tray.

[0022] The electronic scale of this invention features a single, error-preventing installation sequence for assembling the weighing pan and water tray on the scale body.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, and not all of them. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the utility model without creative effort are within the scope of protection of the utility model.

[0033] See Figures 1 to 6 .

[0034] This utility model discloses an electronic scale, including a scale body 1, a scale pan 2 on the top of the scale body 1, a drain hole 4 on the top surface of the scale pan 2, and a water receiving tray 3 below the scale pan 2 corresponding to the position of the drain hole 4, with a drain hole 6 on the water receiving tray 3.

[0035] The purpose of this design is that if there is water on the goods being weighed, the water can fall through the drain hole 4 onto the water receiving tray 3 and drain away along the drain hole 6. Therefore, water will not enter the scale body 1, avoiding water entering the scale body 1 and affecting its lifespan.

[0036] A first positioning block 9 is detachably installed at the top center of the water receiving tray 3, a second positioning block 14 is fixed at the top of the scale body 1, a positioning rod 8 is concentrically fixed at the bottom of the scale pan 2, and a positioning hole 15 is opened at the top of the second positioning block 14.

[0037] The bottom of the positioning rod 8 can pass through the first positioning block 9 and the water receiving tray 3 in sequence to be inserted into the positioning hole 15. The first positioning block 9 is provided with a first locking component, and the second positioning block 14 is provided with a second locking component.

[0038] When the positioning rod 8 passes through the first positioning block 9 and inserts into the second positioning block 14, the first locking component and the second locking component respectively lock the relative positions of the first positioning block 9 and the water receiving tray 3, and the relative positions of the weighing pan 2 and the second positioning block 14, making disassembly convenient.

[0039] In practice, when assembling the scale body 1, it is only necessary to first install the first positioning block 9 at the top center of the water receiving tray 3, and then insert the bottom of the scale pan 2 through the first positioning block 9 and the water receiving tray 3 in sequence, and insert it into the positioning hole 15 of the second positioning block 14 to complete the installation and fixation of the water receiving tray 3 and the scale pan 2 on the scale body 1, which is convenient and reliable.

[0040] This application improves upon the existing structure of the electronic scale's body and pan, enabling efficient assembly and disassembly of the pan 2 and water tray 3 onto the scale body 1. This facilitates subsequent maintenance, cleaning, or replacement of the water tray 3 and pan 2. Simultaneously, it allows for rapid drainage of water from the pan 2, preventing water from entering the scale body 1 and affecting its lifespan.

[0041] In one embodiment, the first positioning block 9 has a first through hole 91 through which the positioning rod 8 passes, and the water receiving tray 3 has a second through hole 18 through which the positioning rod 8 passes, so that the positioning rod 8 passes through the first positioning block 9 and the water receiving tray 3.

[0042] In one embodiment, the top of the water receiving tray 3 is provided with a positioning groove 10 for inserting the first positioning block 9, the bottom wall of the positioning groove 10 is provided with an insertion rod 11 parallel to the positioning rod 8, and the bottom of the first positioning block 9 is provided with an insertion hole 12 that cooperates with the insertion rod 11.

[0043] In this embodiment, the gate positioning groove 10 can realize the initial installation and positioning of the first positioning block 9 on the water receiving tray 3, and the setting of the insertion rod 11 and the insertion hole 12 can improve the stability of the first positioning block 9 after installation on the water receiving tray 3.

[0044] In one embodiment, the first locking component includes a locking rod 16 radially elastically inserted into the first positioning block 9, and a locking hole 17 is provided on the outer wall of the locking rod 11; the end of the locking rod 16 away from the locking hole 12 has a first inclined surface 13, and when the positioning rod 8 passes through the first positioning block 9, the positioning rod 8 presses against the first inclined surface 13, forcing the end of the locking rod 16 near the locking hole 17 to be locked into the locking hole 17.

[0045] Preferably, a support plate 27 is fixed inside the first positioning block, and a locking rod 16 slides through the support plate 27. A first washer ring (not shown) is sleeved and fixed on the outside of the locking rod 16, and a first spring (not shown) is sleeved on the outside of the locking rod 16. The two ends of the first spring are respectively connected to the outer wall of the support plate 27 and the ring wall of the first washer ring.

[0046] It should be noted that when the positioning rod 8 is not inserted into the first through hole 91, the first spring is in a non-deformed state, and at this time the first inclined surface 13 of the locking rod 16 is located inside the first through hole 91. When the positioning rod 8 is inserted into the first through hole 91, it will press against the first inclined surface 13 of the locking rod 16, forcing the locking rod 16 and the first washer to move centrifugally together, at which time the first spring gradually compresses and deforms.

[0047] In specific implementation, when the positioning rod 8 is inserted into the first through hole 91, the bottom of the positioning rod 8 will press against the first inclined surface 13, forcing the locking rod 16 to move centrifugally and lock into the locking hole 17, thereby locking the insertion rod 11 in the insertion hole 12, that is, locking the first positioning block 9 and the water receiving tray 3. As the positioning rod 8 is subsequently inserted into the positioning hole 15 of the second positioning block 14 and used in conjunction with the second locking component, the water receiving tray 3 is finally assembled and fixed on the scale body 1, which is stable and efficient.

[0048] In one embodiment, the second locking component includes an operating rod 21 elastically inserted into the outer wall of the second positioning block 14. One end of the operating rod 21 extends into the second positioning block 14 and is connected to a locking plate 22. The side of the locking plate 22 away from the operating rod 21 has a locking groove 221. The bottom of the positioning rod 8 has a notch 19. The side wall of the notch 19 is provided with a first locking block 20 that cooperates with the locking groove 221. The top of the locking plate 22 has a second inclined surface 222 that slides and presses against the first locking block 20.

[0049] Preferably, a second washer (not shown) is sleeved and fixed on the outside of the operating rod 21, and a second spring (not shown) is sleeved on the outside of the operating rod 21. The two ends of the second spring are respectively connected to the ring wall of the second washer and the corresponding inner wall of the second positioning block 14.

[0050] It should be noted that when the positioning rod 8 is not inserted into the positioning hole 15, the second spring is in a non-deformed state. However, when the bottom of the first locking block 20 moves down and presses against the second inclined surface 222, the second spring gradually compresses and deforms. When the first locking block 20 and the locking groove 221 are engaged with each other, the second spring is in a non-deformed state.

[0051] In specific implementation, when the positioning rod 8 is inserted into the positioning hole 15, the first locking block 20 will press against the second inclined surface 222 after passing through the gap formed by the two guide plates 24, forcing the locking plate 22, the operating rod 21 and the second washer to move away from the positioning hole 15 (the second spring is compressed and deformed) to make room for the first locking block 20 to move down. When the positioning rod 8 is fully inserted into the positioning hole 15, the second spring force is released, which drives the operating rod 21, the second washer and the locking plate 22 to reset and move, so that the locking groove 221 moves toward the first locking block 20 to complete the mutual locking and positioning, thereby realizing the positioning and fixing of the positioning rod 8 in the positioning hole 15, and thus completing the assembly and fixing of the weighing pan 2 on the weighing body 1.

[0052] The positioning hole 15 has a semi-circular cross-section. Two guide plates 24 are arranged opposite each other on the straight side wall of the positioning hole 15. There is a gap between the two guide plates 24 for the first locking block 20 to pass through. When the positioning rod 8 is fully inserted into the positioning hole 15, the second locking block 23 is locked in the gap between the two guide plates 24.

[0053] Preferably, the second locking block 23 has a circular or rectangular cross-section, as long as the second locking block 23 can be matched with the gap.

[0054] It should be noted that the distance of the limited gap is greater than the maximum length of the first card block 20, and the maximum length of the first card block 20 is limited to less than the maximum length of the second card block 23.

[0055] The advantage of this design is that when the positioning rod 8 is fully inserted into the positioning hole 15, the second locking block 23 is locked in the gap, which can help to straighten the positioning rod 8 in the positioning hole 15 and prevent the positioning rod 8 from tilting or falling over when inserted into the positioning hole 15.

[0056] In one embodiment, the top of the water receiving tray 3 is surrounded by a downward sloping ramp 5, the bottom of the ramp 5 is connected to the inlet of the drain hole 6, and the bottom of the water receiving tray 3 is equipped with a drain pipe 7 connected to the outlet of the drain hole 6.

[0057] The advantage of this design is that it can quickly guide the water on the water receiving tray 3 to the bottom of the slope 5, and allow the water to be quickly discharged from the scale body through the drain hole 6 and the drain pipe 7, thereby improving drainage efficiency.

[0058] In one embodiment, the electronic scale of this application is the same as that of a traditional AI electronic scale. Specifically, the scale body 1 of this application has a base plate (not shown) at the bottom. A camera 26 suspended above the weighing pan 2 is mounted on the base plate via a bracket. The bracket also has components such as a display 25. The lower end of the second positioning block 14 is connected to the gravity sensor built into the scale body 1. When the weighing pan 2 weighs the goods, the weight is transmitted to the gravity sensor to achieve weighing. The weight result can be uploaded to the display 25. The product information can be obtained through the camera 26 and displayed synchronously on the display 25 after processing. Its principle is the same as that of a traditional AI electronic scale, and will not be described in detail here.

[0059] It should be noted that the weighing pan 2 and water receiving pan 3 of the electronic scale of this application are assembled on the scale body 1 with a single installation sequence to prevent incorrect assembly. That is, the first positioning block 9 is assembled between the water receiving pans 3 first, then the water receiving pan 3 is placed on top of the second positioning block 14, and then the bottom of the positioning rod 8 is inserted through the first through hole 91, the second through hole 18, and the positioning hole 15 in sequence to complete the assembly of the water receiving pan 3 and the weighing pan 2 on the scale body 1. The advantage of this design is that it can greatly improve the efficiency of disassembling and assembling the water receiving pan 3 and the weighing pan 2 on the scale body 1 and avoid errors.

[0060] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0061] It should be noted that if the utility model embodiment involves directional indicators (such as up and down), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0062] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, if the utility model embodiments involve descriptions of "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. Furthermore, "multiple" refers to two or more. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the utility model.
