[0019] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0020] Please see Figures 1-3As shown, the purpose of this embodiment is to provide an embedded weighing balance in a hazardous chemical storage cabinet, including a weighing balance 1, which includes a body 2 and an electronic scale 3. A display screen 4 is fixedly installed on the upper part of the body 2. The display screen 4 has functions such as supporting personnel information management, supporting hazardous chemical status management, supporting RFID tag and weight automatic identification, automatically generating ledger records, supporting query functions, supporting linkage with reagent cabinets, and supporting abnormal operation scenario settings and early warning reminders. A camera 5 is fixedly installed directly above the display screen 4. The camera 5 has a recognition range of 30cm-120cm, a horizontal field of view of 85°, and supports face liveness detection. The electronic scale 3 is fixedly installed in the middle of the body 2. The electronic scale 3 includes a tray 6 and two weighing sensors 7. The weighing sensors 7 are used to measure the mass of objects placed on the tray 6.
[0021] The weighing balance 1 is fixedly installed inside the hazardous chemical storage cabinet. Horizontal support feet 10 are provided at the four corners of the bottom of the weighing balance 1. The weighing balance 1 has four horizontal support feet at the bottom to facilitate leveling and positioning.
[0022] The main body 2 is L-shaped, and the lower part of the main body 2 is trapezoidal. The lower trapezoidal inclined surface of the main body 2 is equipped with an IC card reader 8 and a QR code scanning port 9. The IC card reader 8 is used for staff to swipe cards for identification. The shell of the main body 2 is made of steel plate structure. The inner and outer surfaces of the main body 1 are treated with pickling, phosphating, epoxy resin powder spraying, and heat curing.
[0023] The electronic scale 3 is fixedly installed on the trapezoidal horizontal surface at the bottom of the machine body 2. The electronic scale 3 is electrically connected to the display screen 4 through a cable, and the value obtained by the electronic scale 3 is transmitted to the display screen 4 and displayed.
[0024] The tray 6 is rectangular, with all four sides extending above the center to form a protective enclosure and prevent items from falling off. The tray 6 is made of polyethylene. The tray 6 can be removed and replaced from the electronic scale 3.
[0025] The weighing sensor 7 includes a sensing element 11 and a conversion element 12. The two weighing sensors 7 are respectively fixedly installed at both ends of the trapezoidal horizontal plane of the machine body 2, and the side wall of the weighing sensor 7 is provided with a connection port 13. The connection port 13 is electrically connected to the display screen 4 through a cable, and the changing electrical signal is transmitted to the display screen 4 through the connection port 13.
[0026] One end of the sensitive element 11 is connected to the bottom of the tray 6, and the other end of the sensitive element 11 is in close contact with the conversion element 12. The sensitive element 11 deforms and acts on the conversion element 12, causing the conversion element 12 to deform and change its resistance value, thereby changing the electrical signal.
[0027] In practical use, the present invention first authenticates the user's identity by using the facial recognition system on the display screen 4 or by swiping an IC card on an IC card reader. Then, the required item is input into the display screen 4. The user retrieves the required item according to the instructions on the display screen 4 and places it on the tray 6. The weighing sensor 7 senses the weight change of the tray 6, causing the sensitive element 11 to deform and act on the conversion element 12. This causes the conversion element 12 to deform and its resistance value to change, thereby changing the electrical signal. The changed electrical signal is transmitted to the display screen 4 through the connection port 13, and the display screen 4 converts the change in electrical signal into the mass of the object and displays it.
[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
