Description

Technical Field

[0001] This utility model relates to the field of automated testing equipment technology, and more specifically, to a multi-functional pressure detection device for thermos cups. Background Technology

[0002] A thermos is a container with a sealed top and an internal vacuum insulation layer, usually made of stainless steel or ceramic. Its core principle is to insulate heat conduction and convection through a vacuum layer, thereby significantly slowing down heat loss from the internal liquid (such as water, coffee, etc.) to achieve long-term heat preservation or cold preservation. The quality indicators of a thermos include pressure resistance and flow characteristics. Pressure resistance is reflected in the fact that the thermos stores liquids such as hot water and carbonated beverages (such as cola and Sprite). Excessive pressure inside the container during use can easily lead to explosions, flying parts, and other safety hazards. Flow characteristics are reflected in thermos cups with straws and spouts. We aim to reasonably control the flow rate of thermos cups, evaluating the size of the straw and spout, and the seal between the straw and the cap from a structural design perspective. Insufficient seal between the straw and cap, or excessively large straws and spouts, make it difficult for users to drink water. Excessive flow can cause choking, especially for children. Similarly, excessively small straws and spouts result in small water intake and a less satisfying user experience. Therefore, manufacturers of thermos cups urgently need a comprehensive device to test the flow rate and pressure of thermos cups. Utility Model Content

The gas storage tank 101 is connected to the first reversing valve 106 through a gas pipe. The first reversing valve 106 is connected to the vacuum generator 102 and the solenoid valve 103. The vacuum generator 102 is connected to the solenoid valve 103 through a valve. The solenoid valve 103 is connected to the pressure transmitter 104. The pressure transmitter 104 is connected to the pressure control gauge 105. The pressure control gauge 105 is connected to the second reversing valve 107. One end of the second reversing valve 107 is connected to the collection bottle 108. Two positive and negative pressure gas pipe lines are formed for testing the pressure and flow rate of the thermos cup 116.

[0023] Reference Figure 1-4As shown, the weighing module includes a first electronic scale 109 and a second electronic scale 110. A collection bottle 108 is placed on the first electronic scale 109. The first electronic scale 109 is used to weigh the water inside the collection bottle 108 and the water inside the thermos cup 116. Furthermore, a limiting plate 112 is provided on the workbench 10. The limiting plate 112 has two through holes, corresponding to the first electronic scale 109 and the second electronic scale 110 respectively.
