Description

Technical Field

[0001] The utility model relates to a fake wine identification device, in particular to a liquid vibration frequency generating device. Background Art

[0002] In order to deal with fake wines with a high level of counterfeiting on the market, such as those with extremely similar appearances, replacing the wine body by pulling out the head of the wine bottle (pulled-head wine), replacing the wine body by drilling holes in the wine bottle (drilled-hole wine), etc., it is necessary to identify the wine body to distinguish. At present, the identification of the wine body is generally achieved by manually shaking the wine bottle to generate wine flowers and listening to the wine flowers. Although manually listening to the wine flowers directly points to the wine body itself, due to its reliance on personal experience alone, it cannot be replicated and spread, and human judgment is also prone to errors. Therefore, if a device that can simulate manual shaking can be developed to shake the wine bottle to generate wine flowers, the accuracy and stability of the wine flower audio data can be well guaranteed. Content of the Utility Model

[0003] The purpose of the utility model is to provide a liquid vibration frequency generating device. The utility model can simulate manual shaking of the wine bottle, ensure the stable and reliable generation of wine flowers, so that the audio pickup module can collect accurate, stable and reliable wine flower audio data.

[0004] The technical solution of the utility model: A liquid vibration frequency generating device includes a housing. Rotating bases and driving mechanisms are respectively arranged on two symmetric sides of the housing. A swing-type wine bottle fixing rack is connected between the rotating base and the driving mechanism through a rotating shaft; an audio pickup module is further arranged in the swing-type wine bottle fixing rack, and the audio pickup module is connected to a main control module.

[0005] In the liquid vibration frequency generating device described above, the swing-type wine bottle fixing rack includes a bottom support plate. Vertical brackets connected to the rotating shaft are arranged on both sides of the bottom support plate. One or more arc-shaped brackets distributed up and down are arranged inside the vertical brackets. A telescopic rod is arranged between the arc-shaped bracket and the vertical bracket, and a spring is sleeved on the telescopic rod.

[0006] In the liquid vibration frequency generating device described above, a Bluetooth module is further arranged on the main control module, and the Bluetooth module is connected to an intelligent control terminal.

[0007] Compared with the prior art, by arranging a rotating base and a driving mechanism on two symmetric inner walls of the housing, and arranging the swing-type wine bottle fixing rack between the rotating base and the driving mechanism, the driving mechanism drives the swing-type wine bottle fixing rack and the wine bottle fixed thereon to swing at a set frequency, so as to simulate the manual swinging method, thereby ensuring the stability and accuracy of the generation of wine flowers and ensuring that the wine flower audio data collected by the audio pickup module is stable and accurate.

Detailed implementation manners

[0012] The present utility model will be further described below in conjunction with the drawings and embodiments, but it shall not be used as a basis for limiting the present utility model.

[0013] Embodiment. A liquid vibration frequency generating device is configured as shown in Figures 1-3 and includes a housing 1. Rotating bases 2 and a driving mechanism 3 are respectively arranged on two symmetric sides of the housing 1. A swing-type wine bottle holder 5 is connected between the rotating base 2 and the driving mechanism 3 through a rotating shaft; an audio pickup module 6 is further arranged inside the swing-type wine bottle holder 5, and the audio pickup module 6 is connected to a main control module 4.

[0014] The swing-type wine bottle holder 5 includes a bottom support tray 501. Vertical brackets 502 connected to the rotating shaft are arranged on both sides of the bottom support tray 501. One or more arc brackets 503 distributed up and down are arranged inside the vertical brackets 502. A telescopic rod 504 is arranged between the arc bracket 503 and the vertical bracket 502, and a spring 505 is sleeved on the telescopic rod 504.

[0015] A Bluetooth module is further arranged on the main control module 4, and the Bluetooth module is connected to an intelligent control terminal.

[0016] A hollow rotating platform is arranged on the driving mechanism. A hollow rotating shaft connected to the swing-type wine bottle holder is installed inside the hollow rotating platform. The audio pickup module passes through the hollow rotating platform and the hollow rotating shaft through a bracket and is placed in a through hole of the swing-type wine bottle holder, so that its position can be kept unchanged.

[0017] A through hole for placing the audio pickup module is arranged on the vertical bracket on one side of the driving mechanism.

[0018] The audio pickup module is located inside the bottom support tray and is connected to the main control module through a retractable connecting wire.

[0019] The housing is a sound-insulating and sealed box.

[0020] The driving mechanism is a rotary drive motor.

[0021] The driving mechanism includes a drive motor. A coupling is provided at the output end of the drive motor and is connected to the rotating shaft. The other end of the rotating shaft is installed in a bearing within the rotating base.

[0022] When the wine bottle is placed into the swing-type wine bottle fixing rack, its bottom is placed on the bottom support plate, and both sides are fixed by arc-shaped brackets. The arc-shaped brackets are fixed to the vertical bracket through telescopic rods and springs, so as to adapt to different wine bottles.

[0023] The working process of the present utility model: Place the wine bottle to be tested into the swing-type wine bottle fixing rack, then the driving mechanism starts to work, driving the swing-type wine bottle bracket to swing, and further driving the wine bottle to be tested and the wine body inside it to swing and rotate (rotate around the rotating shaft). According to the set time and amplitude, shake the bottled wine to be tested to generate wine foam inside the bottled wine. The audio data of the wine foam is collected by the audio pickup module of the wine foam, and the audio data is transmitted to the main control module through the audio pickup module. The main control module transmits the audio data to the intelligent control terminal through the Bluetooth module. The software of the intelligent control terminal processes and analyzes the audio data to judge the authenticity of the wine body.
