Description

Technical Field

[0001] This utility model relates to the field of weighing instrument technology, and in particular to a weighing unit module for a weighing instrument. Background Technology

[0002] Weighing units are widely used in many fields such as industry, commerce, scientific research, and medicine for the precise measurement and monitoring of the weight of objects. For example, in industrial production, they are used in batching systems, material metering, and product quality control; in the commercial sector, they are used in measuring equipment such as electronic scales and price-computing scales; in scientific research, they are used for the precise measurement of experimental samples; and in the medical field, they are used in weighing scales and weight-measuring components in medical equipment.

[0003] Currently, one type of weighing unit module for weighing instruments lacks a mechanism to guide and drain overflowing liquid when weighing containers that are prone to spillage. This allows the overflowing liquid to potentially enter the weighing module and damage its internal electronic components, resulting in significant limitations and poor practicality. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing technologies, when weighing containers that are prone to overflowing liquid, lack a mechanism to guide and drain the overflowing liquid, which may cause the overflowing liquid to enter the weighing module and damage its internal electronic components, resulting in significant limitations and poor practicality. Therefore, this invention proposes a weighing unit module for weighing instruments.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a weighing unit module for a weighing instrument, comprising a base shell, a weighing sensor installed inside the base shell, a measuring circuit board installed at one end of the weighing sensor inside the base shell, a weighing pan mounting component installed at the top of the base shell, the bottom end of the weighing pan mounting component being mounted to the weighing sensor, and a liquid collection and drainage groove being provided on the outside of the weighing pan mounting component at the top of the base shell.

[0006] Preferably, a weighing pan limiting device is installed at the top of the weighing sensor, and the weighing pan mounting component is fixed to the weighing sensor through the weighing pan limiting device.

[0007] Preferably, a communication connector is installed at one end of the base housing, and a running indicator light is installed on one side of the communication connector. The communication connector, the running indicator light, and the weighing sensor are all electrically connected to the measuring circuit board.

[0008] Preferably, mounting covers are installed at both ends of the base housing.

[0009] Preferably, a base plate is fixed to the bottom of the base shell, and multiple mounting holes are provided on both sides of the base plate.

[0010] Preferably, a first baffle is fixed to the top of the inner ring of the liquid collection and drainage trough, and a second baffle is fixed to the bottom of the weighing pan mounting component.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, a liquid collection and drainage trough is installed on the base shell and outside the weighing pan mounting component. When an item on the weighing pan mounting component is weighed and liquid overflows, the liquid will fall into the liquid collection and drainage trough and be automatically discharged through the drainage port of the trough, preventing it from entering the base shell. A first baffle, which is relatively long and located at the top of the inner wall of the liquid collection and drainage trough, can block splashing liquid dripping into the trough, preventing it from entering the base shell, thus providing stronger protection. A second baffle prevents overflowing liquid from flowing into the base shell through the bottom of the weighing pan mounting component, further improving the liquid-proof effect and enhancing practicality. The first and second baffles also provide overload protection, further enhancing practicality. Attached Figure Description

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, such as Figure 1-4 As shown, this utility model provides a weighing unit module for a weighing instrument, including a base shell 1, a weighing sensor 3 installed inside the base shell 1, a measuring circuit board 11 installed at one end of the weighing sensor 3 inside the base shell 1, a weighing pan mounting component 7 installed at the top of the base shell 1, the bottom end of the weighing pan mounting component 7 being installed with the weighing sensor 3, and a liquid collection and drainage groove 8 being opened on the outside of the weighing pan mounting component 7 at the top of the base shell 1.

[0021] The overall effect of Embodiment 1 is as follows: by installing a weighing pan on the weighing pan mounting component 7, and placing the item to be weighed on the weighing pan, the weighing item will cause the weighing pan mounting component 7 to descend. The weighing sensor 3 will generate corresponding strain according to the pressure or tension it receives, which will cause changes in electrical quantities such as resistance, thereby outputting an electrical signal proportional to the weight. The measuring circuit board 11 is responsible for processing the electrical signal output by the weighing sensor 3, including amplification, filtering, analog-to-digital conversion, etc. Its internal microprocessor analyzes, calculates and stores the processed data, and controls the operation of the entire module according to the preset program and algorithm. At the same time, it interacts with external devices through the communication connector 5. Through the setting of the liquid collection and drainage tank 8, which is set on the base shell 1 and outside the weighing pan mounting component 7, when the item on the weighing pan mounting component 7 is weighed and liquid overflows, the liquid will fall into the liquid collection and drainage tank 8 and be automatically discharged through the drainage port of the liquid collection and drainage tank 8, preventing it from entering the base shell 1.

[0022] Example 2, as Figure 1-4 As shown, a weighing pan limiting device 4 is installed at the top of the weighing sensor 3. The weighing pan mounting component 7 is fixed to the weighing sensor 3 through the weighing pan limiting device 4. A communication connector 5 is installed at one end of the base housing 1. A running indicator light 6 is installed on one side of the communication connector 5. The communication connector 5, the running indicator light 6, and the weighing sensor 3 are all electrically connected to the measuring circuit board 11. Mounting covers 2 are installed at both ends of the base housing 1. A base plate 9 is fixed at the bottom of the base housing 1. Multiple mounting holes 10 are opened on both sides of the base plate 9. A first baffle 12 is fixed at the top of the inner ring of the liquid collection and drainage tank 8. A second baffle 13 is fixed at the bottom of the weighing pan mounting component 7.

[0023] The overall effect of embodiment 2 is that, through the setting of the first baffle 12, the first baffle 12 is relatively long and is located at the top of the inner wall of the liquid collection and drainage tank 8, which can block the splashing liquid dripping into the liquid collection and drainage tank 8 and prevent it from entering the base shell 1, thus providing stronger protection. Through the setting of the second baffle 13, the overflowing liquid is prevented from flowing into the base shell 1 through the bottom of the weighing pan mounting component 7, thus providing better liquid prevention and stronger practicality. In addition, the setting of the first baffle 12 and the second baffle 13 can also play the role of overload protection, thus further enhancing practicality.

[0024] Working Principle: When in use, the weighing pan is installed on the weighing pan mounting component 7, and the item to be weighed is placed on the weighing pan. The weighted item causes the weighing pan mounting component 7 to descend. The load cell 3 generates corresponding strain based on the applied pressure or tension, resulting in changes in electrical quantities such as resistance, thereby outputting an electrical signal proportional to the weight. The measuring circuit board 11 processes the electrical signal output by the load cell 3, including amplification, filtering, and analog-to-digital conversion. Its internal microprocessor analyzes, calculates, and stores the processed data, and controls the operation of the entire module according to preset programs and algorithms. Simultaneously, it interacts with external devices via the communication connector 5. The liquid collection and drainage tank 8, located on the base housing 1 and on the weighing pan mounting component, facilitates the operation of the weighing pan. On the outside of the weighing pan mounting component 7, when the items on the weighing pan mounting component 7 are weighed and liquid overflows, the liquid will fall into the liquid collection and drainage tank 8 and be automatically discharged through the drainage port of the liquid collection and drainage tank 8, preventing it from entering the base shell 1. With the setting of the first baffle 12, the first baffle 12 is relatively long and is located at the top of the inner wall of the liquid collection and drainage tank 8, which can block the splashing liquid dripping into the liquid collection and drainage tank 8 and prevent it from entering the base shell 1, thus providing stronger protection. With the setting of the second baffle 13, the overflowing liquid is prevented from flowing into the base shell 1 through the bottom of the weighing pan mounting component 7, thus providing better liquid prevention and stronger practicality. In addition, the setting of the first baffle 12 and the second baffle 13 can also provide overload protection, further enhancing practicality.

Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the weighing sensor 3, communication connector 5, and operation indicator 6 will not be explained in detail.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
