Background technique

With the development and progress of science and technology, the development of products gradually tends to be multi-functional, humanized, portable and miniaturized. More and more people start to pay attention to the design of products with high portability and multiple functions.

At present, the design of portable small or miniature pocket scales is relatively single. On the one hand, the pursuit of miniature pocket scales is blindly pursued, resulting in the continuous shrinkage of its volume and a great impact on its functions. The maximum load of some miniature pocket scales is also Small, so it's less practical. On the other hand, the main function of current pocket scales is to weigh the quality of articles, and there are few products with additional functions. Even if some pocket scales are added with some functions such as magnifying glass, their practicability is also weak. Secondly, the main usage scenario of portable small or miniature pocket scales is when shopping, and the function is easy to carry and use and weigh the quality of items. Under such a premise, a new problem is brought. If the quality or quantity of the purchased items is large, the handle of the plastic bag containing the items is narrow and the contact surface with the fingers is narrow, resulting in a large pressure. Carrying items by hand for a long time can cause hand discomfort and pain.

Contents of the invention

The purpose of the utility model is to provide a ring-shaped portable electronic scale with a handle, which solves the problems of single function and poor practicability of the pocket scale.

The technical solution to realize the purpose of the utility model is: a ring-shaped portable electronic scale, including a ring handle, a pressure sensor, a control unit, a power switch, an electronic display screen and a calibration reset button.

The outer wall of the ring-shaped handle is provided with grooves, and N pressure sensors are arranged in the grooves, N≥1; the control unit, power switch, electronic display screen and calibration reset button are all arranged on the ring-shaped handle, and the control units are respectively It is connected with the pressure sensor, power switch, electronic display and calibration return button, the power switch is connected with the electronic display, the power switch is connected with the battery, the battery supplies power to the control unit and the electronic display, and the handle part of the plastic bag is hung on the ring On the handle, the pressure is applied to the pressure sensor, the deformation of the pressure sensor causes the circuit impedance to change, and a changed analog signal is output. The signal is amplified by the circuit and output to the control unit. The control unit converts it into a weight value and sends it to the The electronic display is displayed on the electronic display, that is, the quality of the items in the plastic bag can be known through the reading of the electronic display.

The groove is arranged along the outer arc of the ring handle.

The N pressure sensors are arranged side by side at the place where the pressure of the handle of the plastic bag to the ring handle 1 is concentrated.

The calibration return-to-zero button is used to reset the ring-shaped portable electronic scale to its original state.

Compared with the prior art, the utility model has the remarkable advantages of:

(1) Combining a miniature electronic scale with a handle to realize one thing with multiple functions and bring convenience to users.

(2) The miniature electronic scale is small and easy to carry, and its pressure sensor is set in the groove on the top of the handle, which is more convenient for weighing the quality of the item than the scale hook.

(3) The ring-shaped handle is more convenient for carrying items with larger quality or quantity.
