充气模型充气管的防倒塌结构及含该结构的风机Anti-collapse structure of inflatable model inflatable tube and fan containing the same 技术领域Technical field
本实用新型涉及充气模型排气领域，更具体地说，涉及一种充气模型充气管的防倒塌结构及含该结构的风机。The utility model relates to the field of inflatable model exhaust, and more particularly to an anti-collapse structure of an inflatable model inflation tube and a fan comprising the same.

Because the air mold has the advantages of light weight, convenient carrying, and easy to cast, it is widely used in large advertising, inflatable rides and other fields. After the air mold is used, the internal gas needs to be emptied to be removed and transported. Since the air mold usually has only one air hole, the process of exhausting the large air mold is very slow, and the operator will spend a lot of time. Wait for the gas in the air mold to empty. However, if a fan is specifically provided to pump the air, the cost is too high, and the frequency of use is not high, resulting in waste.
而在风机上设置的一种进风口装置，使风机在原有的为气模充气的基础上，增加了为气模抽气的功能。在该装置对气模进行抽气作业的流程中，气模在内部气体抽出的过程中，会因自身的重量逐渐下坠。在气模内空气接近完全抽出的时候，气模的下坠很容易时气流通道内侧的口部或其本身的下坠，导致抽气时的气流量减少甚至气流通道完全堵塞，从而使抽气作业在气模内还有大量空气时便不能继续进行，影响到抽气效果和效率。The air inlet device provided on the fan increases the function of pumping the air mold on the basis of the original air mold inflation. In the process in which the device performs a pumping operation on the air mold, the air mold gradually falls due to its own weight during the process of extracting the internal gas. When the air in the air mold is nearly completely extracted, the falling of the air mold is easy when the mouth inside the air passage or its own falling, resulting in a decrease in the air flow during the pumping or even the air passage is completely blocked, so that the pumping operation is When there is a large amount of air in the air mold, it cannot continue, affecting the pumping effect and efficiency.
