Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of water cup production, and in particular relates to an instrument for detecting leakage of a vacuum container by using sound. Background Art
[0002] Existing metal insulation containers, such as thermos cups and flasks, all adopt a double-layer structure, and then evacuate the double-layer structure to form a vacuum layer, which realizes the insulation function. The vacuum degree of the metal insulation container is the key factor to ensure the insulation performance. The higher the vacuum degree of the insulation container, the better its insulation performance. Therefore, the detection of vacuum degree (i.e. insulation performance) is very important for metal insulation containers.
[0003] Currently, the industry uses the principles of thermodynamics to detect the vacuum leakage of metal insulation containers. The specific detection method is as follows: by spraying hot air at a certain temperature into the container, the inner side of the insulation container is continuously heated. After heating for a certain period of time, the operator touches the outer surface of the insulation container and manually senses the temperature of the outer surface of the insulation container to determine whether the vacuum degree (insulation performance) of the insulation container meets the standard; when the vacuum degree of the insulation container does not meet the standard, there will be more air in the vacuum layer, so that the heat on the inside of the insulation container will quickly transfer to the outer surface of the insulation container, causing the outer surface of the insulation container to reach a higher temperature. Therefore, the higher the temperature of the outer surface of the insulation container, the worse the vacuum degree (insulation performance) of the insulation container.
[0004] The existing detection method requires the use of subjective manual judgment and is unable to accurately and quantitatively detect the vacuum degree of the thermal insulation container, resulting in large detection errors. In addition, hot air or hot water is required during the detection process, and hot air or hot water is generated by heating the air with electric energy, which consumes a lot of electric energy. Utility Model Content
[0005] The purpose of the utility model is to provide an instrument for detecting leakage of a vacuum container by using sound in view of the above-mentioned existing technical problems, so as to achieve the effects of low energy consumption and simple detection method.
[0006] In view of this, the utility model provides an instrument for detecting leakage of a vacuum container by using sound, comprising a machine base, on which are arranged:

[0009] A sound sensor is arranged inside the container and is used to receive sound. The sound sensor is connected to a computer.
[0010] In the technical solution, the container to be tested is fixed by a positioning component and a clamping component, and then the knocking component knocks on the outer bottom of the container. The sound sensor inside the container receives the sound and transmits the signal to the computer. The computer analyzes the sound and the interlayer is evacuated, which cuts off the transmission of the sound. If the calculated received sound intensity is low and does not exceed the specified value, the vacuum interlayer of the container is not leaking. The instrument has low energy consumption and a simple detection method.
[0011] Further, the striking power source includes:

[0015] In this technical solution, the rotary cylinder is started, driving the turntable to rotate a certain angle, which can drive the fixed pin to rotate around the axis of the turntable, so that the driving member can rotate and extend along the direction of its own slide groove. During the rotation and movement of the driving member, the hammer will hit the outer bottom of the container.
[0016] Furthermore, the container is invertedly arranged on a mounting frame, the hammer is located above the outer bottom of the container, and the sound sensor extends into the inner cavity of the container from the inlet end below the container.

[0018] Furthermore, a supplementary sleeve is detachably fixedly connected above the partition, the supplementary sleeve is coaxial with the clearance hole, and the inner wall of the supplementary sleeve matches the outer shape of the container.
[0019] In the present technical solution, the supplementary sleeve can position the container more accurately, reduce the chance of the clamping assembly being clamped off-center, and increase stability under hammer impact during the detection process.
[0020] Furthermore, the clamping assembly is a pneumatic finger, which is fixed on the partition and is used to clamp the outer periphery of the container.
[0021] Furthermore, the inlet end of the container extends out of one end of the supplementary sleeve away from the partition, and a sealing piece is provided at the end of the inlet end of the container. The sealing piece is used to cover the inlet of the container. A first connecting hole is opened on the sealing piece, and a nut is fixedly connected in the first connecting hole.

If the calculated received sound intensity is low and does not exceed the specified value, the container vacuum interlayer does not leak vacuum. This instrument has low energy consumption and a simple detection method.
