Description

Technical Field

[0001] The utility model relates to the technical field of electronic scales, in particular to an electronic scale with a directional voice prompt function. Background Art

[0002] In the buffet restaurant service scenario, electronic scales are an important tool for weighing and settling food ingredients. Their functionality and user experience directly affect the restaurant's operating efficiency and service quality. Although some existing electronic scale products have integrated voice functions to announce weighing results or abnormal situations, there are significant deficiencies in actual applications. A common problem is that most of these electronic scales are only equipped with ordinary speakers for large-scale non-directional voice broadcasting, and cannot achieve accurate directional sound transmission.

[0003] When there are many people in the restaurant, multiple electronic scales may send voice prompts to the surrounding environment at the same time period. This indiscriminate sound diffusion causes noise interference to the dining area, making it impossible for consumers to determine the exact source of the voice broadcast when picking up food, reducing consumers' dining comfort and not conducive to creating a good dining atmosphere. It also makes it difficult for staff to accurately determine the source and specific content of each voice prompt, such as which electronic scale may have insufficient balance or unbound tray, etc. Work efficiency is significantly restricted, delaying the response speed to problems.

[0022] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0023] Reference Figure 1-4 The utility model proposes an electronic scale with a directional voice prompt function, including an electronic scale body 1 with a PCB board inside and a weighing panel 2. The electronic scale body 1 is also connected to a column 3, and the upper end of the column 3 is rotatably connected to a meter head 4. The meter head 4 is provided with a speaker 41 connected to the PCB board.

[0024] The speaker 41 is set on a rotatable head 4. The direction of the directional speaker 41 can be adjusted arbitrarily according to the on-site use environment to make the sound propagate in the designated area, effectively preventing the sound pollution of the business premises by voice prompts. For example, in a buffet restaurant, the existing speakers are directly installed on the electronic scale body 1, and the sound pollution is very serious through the large-scale non-directional propagation of the speaker. If there are multiple electronic scales side by side, the situation is even more serious, and it is even impossible to judge whether the sound is transmitted from the electronic scale in front or the electronic scales on both sides. However, by setting the direction of the directional speaker 41, the sound of the speaker is only propagated to the front, weakening the sound transmitted to the sides.

[0025] It should be noted that the electronic scale body 1 is also connected to a column 3, which specifically includes a signal connection or a direct structural connection, and the column includes structures such as signal lines and electric wires.

The upper end of the column 3 is provided with an elastic member 32 inserted into the matching groove 4221 to limit the rotation of the meter head 4 relative to the column 3. When the meter head 4 is subjected to external force, it can rotate around the axis of the column 3 to make the elastic member 32 move to different matching grooves 4221. In this case, it can be extended so that the meter head 4 can rotate 360° in any direction around the axis of the column 3 when subjected to external force.

[0028] The groove 4221 cooperates with the elastic part 32 at the top of the column 3 to realize the function of the meter head 4 being able to rotate freely around the column 3. In this way, when subjected to external force, the meter head can adjust the angle according to actual needs, thereby improving the flexibility and convenience of using the equipment; ensuring that the meter head 4 can be stably limited after being rotated into place to prevent arbitrary swinging or rebounding, thereby improving the stability of the equipment during operation.
