[0002] In the collective meal service, the heat preservation box is the key equipment to ensure the food temperature stability, and the existing heat preservation box design usually adopts the hinge connection of the box body and the box cover on one side, and uses the lock catch to fix on the other side.
[0003] However, the existing structure has obvious deficiencies: first, due to the existence of the hinge, the box body and the box cover cannot be easily separated, which brings inconvenience to daily cleaning, because the large number and the unstable state of the box body and the box cover due to the weight difference when opening and cleaning make the manual cleaning workload large and the work difficult, and the existing mechanical equipment cleaning needs to separate the box body and the box cover for cleaning; secondly, the sealing performance of the hinge side is poor, because the hinge usually needs to be installed between the box body and the box cover by screws to facilitate the opening and closing of the box cover, the connection mode of the hinge will form a certain gap or gap at the hinge, even if there is a sealing ring, it is also difficult to completely eliminate these small spaces, therefore, in the case of only one layer of sealing ring and without heating equipment inside the heat preservation box, the hinge side further aggravates the internal temperature loss, greatly reducing the heat preservation effect.
[0004] In addition, for the collective meal service, the number of heat preservation boxes is large, and there are many staff and meal takers, so the traditional key lock or password lock is not convenient enough - the former requires the staff to carry multiple keys, and the latter increases the operation complexity, more importantly, these two locking modes cannot provide effective opening and closing records, so it is difficult to ensure food safety, and there is potential risk.
