Anti-skid tray based on air pressure adsorption

Abstract

The invention discloses an anti-skid tray based on air pressure adsorption. The tray comprises a supporting plate, and a liquid storage cavity is formed in the supporting plate; the liquid storage cavity is filled with low-boiling-point evaporation liquid; a heat conducting plate is fixedly inserted into the upper wall of the supporting plate; and the heat conduction plate is of a T-shaped structure. The lower end of the heat conduction plate extends into the liquid storage cavity; the upper wall of the liquid storage cavity communicates with two containing cavities through two connecting pipes. The side walls of the ends, close to the connecting pipe, of the two containing cavities are elastically connected with driving magnetic blocks through reset springs. The ends, away from the driving magnetic blocks, of the two containing cavities communicate with the outside through air outlet pipes, two negative pressure grooves are formed in the upper wall of the supporting plate, driven magnetic blocks are connected to the inner walls of the negative pressure grooves in a sealed and sliding mode, and the driven magnetic blocks and the driving magnetic block attract each other in a heteropolar mode. According to the anti-skid tray, utensils can be effectively prevented from sliding, it is guaranteed that the utensils can be stably placed on the tray, and the tray can be prevented fromsliding when customers have dinner.

Description

technical field [0001] The invention relates to the technical field of daily necessities, in particular to a non-slip tray based on air pressure adsorption. Background technique [0002] A tray is a tool used to hold some serving utensils. In some restaurants, in order to serve food more quickly and conveniently, the waiter usually puts multiple utensils on the tray, and then uses the tray to serve. This can not only effectively improve the efficiency of serving dishes, but also prevent burns caused by direct contact with high-temperature utensils with hands. In addition, with the popularity of some fast food, many fast food restaurants will also provide trays, and customers can use the trays to place some The dishes you need, and when the customer eats, you can also put the food you don’t eat in the tray. The waiter only needs to take the tray away when cleaning, and there is no need to scrub the table carefully. Give the waiter Bring convenience, but, there are following ...

AI Technical Summary

Problems solved by technology

[0003] 1. In restaurants or fast food restaurants, if there are many customers, there will inevitably be some friction and collision. When waiters and customers use the tray, it is easy to make the tray tilt, causing the utensils on the tray to slide, and it is easy to dislodge the contents in the utensils. Spilling of dishes, on the one hand, causes waste, on the other hand, spilling high-temperature food can easily burn other customers or users, causing serious consequences;

[0004] 2. When the customer is eating, the tray is placed on the table. Since the tabletop of the restaurant is generally very smooth, when the customer is eating, it is easy to make the tray slide on the table with a little force, and it is easy to spill the food in the container. Affect customers' dining experience
