Description

TECHNICAL FIELD

[0001] The present application relates to the field of high-mobility cooking support vehicles, in particular to a stable positioning reheating device. BACKGROUND

[0002] The reheating box is one of the core equipment of the high-mobility cooking support vehicle. The reheating box usually has two use modes: vehicle-mounted use mode and backpack use mode. From the perspective of use, it is divided into main food processing and side food reheating. From the perspective of use region, it is divided into general type and high plateau type. In order to ensure the backpack use of the reheating box, the design principle of the reheating box is good environmental adaptability, good air tightness, etc.

[0003] In actual engineering practice, the following problems exist:

[0004] I. The existing reheating box is provided with a steam inlet and outlet, a pressure relief device, a pressure gauge, etc. When the internal steam pressure is too high, the pressure relief device is used for pressure relief.

[0005] However, since the high-mobility cooking support vehicle often works in harsh outdoor environments and is long-term outdoor work, some parts will be more eroded, resulting in a decrease in service life. For example, the spring is easily damaged by wind and rain, resulting in the undesired opening of the pressure relief valve when the internal pressure of the reheating box does not meet the standard. The working environment and tasks of the high-mobility cooking support vehicle determine that the maintenance is difficult.

[0006] Using a two-stage pressure relief double-spring double-insurance method may solve the problem, but the effect is limited because both springs are exposed to harsh environments. If one performance decreases, the probability of the other performance decreasing is also high, and it is not a foolproof solution.

[0007] II. The pressure relief pipeline in the existing reheating box often includes a horizontal section and a vertical section. The pressure relief structure is usually arranged in the vertical section. However, the horizontal section is prone to accumulate impurities (such as some food falling or entering the box in harsh environments), which is not easy to clean after long-term accumulation.

[0008] III. The pressure relief device in the prior art lacks adjustment function for the opening and closing of the pressure relief hole. It may be possible to use some means to achieve closure, but the means is complex.

[0009] IV. The pressure relief device in the prior art lacks a means for quick maintenance and replacement.

[0010] V. The pressure relief device in the prior art is difficult to form two switchable pressure relief paths in a limited space.

[0011] VI. The reheating box of the high-mobility cooking support vehicle in the prior art cannot be stably placed when placed on the vehicle. Moreover, the reheating box is not necessarily placed on the vehicle during use, and it cannot be quickly positioned when reloaded onto the vehicle. SUMMARY
