[0002] A multifunctional digital scale with voice announcement is a weighing device that integrates multiple functions. It not only displays the weight but also announces the weight via voice announcement. This type of scale is commonly used in various applications, including home, commercial, and industrial settings.

[0003] Traditionally, portable scales consist of a load cell, amplifier circuit, A / D converter circuit, single-chip microcomputer circuit, display circuit, keyboard circuit, and other circuits. They typically feature a handle on top and a hook at the bottom, which connects to the load cell. Electronic scales, integrating modern sensor, electronics, and computer technologies, are the only way to meet the real-life requirements of "fast, accurate, continuous, and automatic" weighing. While effectively eliminating human error, they also align with legal metrology management and industrial production process control requirements.

[0004] However, in current life, when most people use electronic scales for measurement, they need to look at the display screen of the electronic scale from time to time to know the pricing results. This not only wastes time and affects the eyes, but also creates a fixed way of thinking for people. It is also easy to cause reading errors due to carelessness, which in turn affects subsequent measurement results. Therefore, how to conveniently know the pricing results of electronic scales, reduce repetitive work of personnel, and improve work efficiency of personnel is a problem that must be solved.

All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1: Please refer to Figure 1-Figure 4 The utility model provides a technical solution: a multifunctional voice broadcast digital display electronic scale, comprising: a scale body 1, a fixed suspension rod 2 is provided at the bottom of the scale body 1, support frames 3 are fixedly connected to both sides of the fixed suspension rod 2, a threaded rod 4 is rotatably sleeved between the two support frames 3, a movable suspension rod 5 is threadedly sleeved on the threaded rod 4, a connector 6 is movably sleeved at the bottom of the movable suspension rod 5 and the fixed suspension rod 2, a hook 7 is movably sleeved at the bottom of the connector 6, one end of the fixed suspension rod 2 is connected to a sensor 8, a circuit board 9 is provided on one side of the sensor 8, and a speaker 10 is installed on one side of the circuit board 9.

[0024] When weighing is required, hold the handle 14 and make the entire scale body 1 perpendicular to the ground. Hang the object on the three hooks 7 at the bottom of the scale body 1. The object stretches the hook 7 downward due to the weight, so that the hook 7 pulls the connector 6, the connector 6 pulls the fixed boom 2 and the mobile boom 5, and the mobile boom 5 pulls the support frame 3, so that the support frame 3 also pulls the fixed boom 2 at the same time. The data signal is transmitted to the circuit board 9 through the sensor 8. The circuit board 9 outputs after data calculation. The circuit board 9 circuit is connected to the speaker 10. The speaker 10 is used to broadcast the final measurement result, thereby reducing the repetitive work of personnel and improving their work efficiency. At the same time, the distance between the two mobile booms 5 can be adjusted by rotating the threaded rod 4, so that the position of the hook 7 at the bottom of the mobile boom 5 can be adjusted, making it easier for the hook 7 to hang the object. In addition, by setting three hooks 7, the stability of the hanging object is further improved, thereby making the measurement result more accurate.

[0025] Example 2: On the basis of Example 1, the threaded rod 4 is rotatably sleeved on both sides of the support frame 3 and the middle of the threaded rod 4 passes through the fixed boom 2. One end of the threaded rod 4 is fixedly connected to a handwheel 11. The threaded rod 4 passes through the support frame 3 and the fixed boom 2 horizontally, so that the threaded rod 4 is supported by the support frame 3 and the fixed boom 2. A handwheel 11 is installed at one end of the threaded rod 4 to facilitate the rotation of the threaded rod 4. A limiting rod 12 is provided on the lower side of the threaded rod 4. The limiting rod 12 passes through the bottom of the fixed boom 2 and the movable boom 5 and the two ends of the limiting rod 12 are fixedly connected to the support frame 3. The limiting rod 12 is fixedly installed in the support frame 3 and the fixed boom 2. The bottom of the movable boom 5 is sleeved on the limiting rod 12 and is slidably connected to the limiting rod 12. The movable boom 5 is limited during movement by the limiting rod 12.

[0026] During the weighing process, in order to improve the stability of the suspended objects and the accuracy of measurement, the threaded rod 4 can be driven to rotate in the support frame 3 by twisting the handwheel 11. Since the threaded rod 4 is threadedly connected to the movable suspension rod 5, and the threaded rod 4 has two sections of threads with opposite rotation directions, the two movable suspension rods 5 can be driven to move toward or away from each other under the forward and reverse rotation of the threaded rod 4, thereby adjusting the distance between the two movable suspension rods 5, thereby facilitating the stability of the lifting hook 7 when hanging different objects, and further improving the accuracy of the measurement results of the objects.

[0027] Example 3: On the basis of Example 2, a sensor 8 is provided on the upper side of the limit rod 12, and the sensor 8 and the circuit board 9 are fixedly installed in the inner cavity of the scale body 1. The sensor 8 and the circuit board 9 are electrically connected, and the sensor 8 and the circuit board 9 are supported by the inner cavity of the scale body 1. The top of the scale body 1 is rotatably connected to the handle 14 through a pin shaft 13. A switch key 15 is installed opposite the speaker 10, and a charging connector 16 is provided on the upper side of the switch key 15. A control display screen 17 is provided on one side of the charging connector 16. The top of the scale body 1 is rotatably connected to the handle 14 through the pin shaft 13, so that the entire scale body 1 can be pulled up by the handle 14. The speaker 10, the switch key 15, the charging connector 16, and the control display screen 17 are all fixedly installed on the outer wall of the scale body 1, and the speaker 10, the switch key 15, and the charging connector 16 are all electrically connected to the circuit board 9.

[0028] The circuit board 9 contains an MCU operation module, an A / D processor conversion module and a Bluetooth module. A battery is provided on one side of the circuit board 9. The battery supplies power to the circuit board 9 and then charges the battery through the charging connector 16. The battery is fixedly installed in the inner cavity of the scale body 1. The handle 14 is tightly gripped by the hand so that the handle 14 drives the scale body 1 vertically to the ground, and the object is hung on the hook 7. The object is stretched downward due to the weight, so that the object pulls the hook 7, and the hook 7 stretches the connector 6. The connector 6 pulls the fixed boom 2 and the mobile boom 5. The fixed boom 2 is directly connected to the sensor 8. The mobile boom 5 pulls the threaded rod 4, the threaded rod 4 pulls the support frame 3, and the support frame 3 pulls the fixed boom 2, so The mobile boom 5 indirectly pulls the fixed boom 2, and the gravity is converted into an analog signal of voltage or current through the sensor 8. After signal amplification, the A / D processor converts it into a digital signal, and the digital signal is processed by the MCU. The MCU receives the voltage signal converted by the analog-to-digital conversion circuit and feeds it back to the liquid crystal display circuit and the Bluetooth circuit. The display circuit is connected to the control display screen 17 to display the weight of the weighed object. The buttons on the control display screen 17 can perform functions such as tare, pricing, and unit switching. The Bluetooth circuit is used to transmit the display results to the mobile phone APP. The voice broadcast circuit is connected to the speaker 10, and the speaker 10 is used to broadcast the final measurement results, thereby avoiding the trouble of repeated checks by personnel and improving the measurement accuracy.
