With the continuous improvement of people's living standard quality, the heat preservation box has also begun to enter our daily life. The heat preservation box is diverse and has different forms. However, no matter how the function and function of the heat preservation box changes, it is inseparable from its origin. It has the effect of heat insulation to achieve heat and cold preservation.

With the cold weather and the peak season of incubators coming, the fast food industry and canteens of enterprises and institutions began to purchase incubators in large quantities. The rapid increase of sales volume of incubators should have been a good thing for the manufacturers of incubators, but there are many problems. "Every year, I get a phone call to ask why the incubator becomes heavy and its insulation performance is reduced after being washed under water. There are even complaints about eating small screws and other accessories of the incubator when eating. In fact, of course, we know the importance of ensuring the safe use of food incubators, and we have paid great attention to product sealing, assembly and quality inspection. Only the problems reported by customers are old problems for many years, and it has been difficult to find a way to fundamentally eliminate them. " Mr. Deng, an incubator manufacturer, complained.

Why does Mr. Deng's problem appear in the incubator? According to the summary of users' field use, we know that the waterproof performance of the insulation box has become a major problem in the insulation box industry.

As engaged in the production and sales of incubators, we are not unfamiliar with the construction of incubators. Both the box cover and the box body are made up of plastic inner and outer layers. In order to ensure tightness, a few screws are generally used to tighten. The polystyrene foam or polyurethane foam insulation layer is filled between the inside of the box cover and the box body. Why does the box become heavy after water cleaning? In the final analysis, it is the cause of poor sealing. Although many screws are used for connection, there are small gaps between the box cover and the inner and outer layers of the box. During cleaning, water will slowly enter the interlayer between the box cover and the box body through these small gaps. Although it will dry or dry after cleaning, it cannot guarantee that the water in the interlayer is completely removed. Over time, the box body is more and more The heavier the water in the interlayer, the worse the insulation of the incubator. In addition, the existence of multiple screws also has hidden dangers to the safety of the incubator. Although many manufacturers will install plastic plugs outside the screws to prevent the screws from falling, as time goes on, the plastic parts will gradually age, resulting in the situation described above: one careless, small screws and plastic plugs and other accessories fall into food, seriously affecting food safety and threatening people. Life and health.

This problem in the incubator industry has lasted for many years. Although the insiders are not afraid to talk about it, they can't solve it. They are helpless. In order to solve this long-standing problem, Suzhou ante industry adopts a unique sealing structure design and new welding technology, which completely subverts people's thinking and changes from "connecting" to "welding". For a long time, the inner and outer layers of the box cover of the incubator have been connected by hand screw. Now we design the joint of the inner and outer layers into a special "snap in" structure, and set up welding rod at the inner joint. After the machine is used to weld the inner and outer layers of the box cover of the incubator, the seamless connection is realized. Because there is no gap between the inner layer and the outer layer, no liquid will enter into the intermediate insulation layer under the condition of cleaning or box rain, so as to avoid the defects of affecting the insulation effect and box weight due to liquid intrusion.
