饮水机到底存在哪些二次污染现象呢。 What kind of secondary pollution is there in the water cooler? 　　首先，有些桶装水的瓶盖密封性并不很好，空气是可以进入的，因此，如果存放桶装水的环境不好，我们拿到的桶装水很可能已经被空气污染了。 First of all, some bottled water bottle cap sealing is not very good, can enter the air is, therefore, if the store bottled water environment is bad, we get the bottled water may have been the air pollution. 　　饮水机的工作原理是，当我们把桶装水的瓶口插入饮水机的聪明座中，我们会听见咕噜咕噜，气泡在桶里升起，水桶的水进入饮水机，但是为什么一会能自动停下来呢?因为聪明座里的水满上来以后，就把里面的进气口封住了，桶里进不去空气，水就不往下流了。但是，聪明座里这时积存的水有很多，大家应该也知道桶颈一直浸泡在水里，这些水最终也会进入饮水机，被饮用。而瓶口这个地方一般是送水工搬运时抓的地方，大家想卫生吗?还有聪明座里面，由于有缝隙时间一长，里面也是很脏，大家看看你办公室里的饮水机就知道了。 The working principle of water dispenser is, when we put the bottle of bottled water in the water dispenser of smart, we can hear the loud gurgling, bubble rises in a bucket, bucket of water into the water dispenser, but why can automatically stop for a while? Because when the water in the smart seat is full, the inside of the inside is sealed and the water will not go down. However, smart seat at this time of stored water has a lot of, you should also know that barrel neck has been soaked in water, the water will eventually enter the water dispenser, been drinking. And the mouth of the bottle is usually a place where the water is carried away. Do you want to be hygienic? There is also a smart seat, because there is a long slot and it is dirty inside, so you can see the water fountain in your office. 　　 　　因为大桶水想要流入饮水器，必须要补入空气，所以整个饮水机循环必须是开放式的。再者，很多饮水机本身质量就不好，内部蓄水罐与聪明座连接缝隙较大，甚至能爬进去小虫子，当我们把聪明座打开，发现里面真是脏得要命。所以，厂家说明书里要求用户定期清洗 Because the bucket of water wants to enter the water fountain, it must be added to the air, so the whole water dispenser cycle must be open. Moreover, a lot of water dispenser itself quality is bad, the internal water storage tank and intelligent bridge connecting aperture is bigger, can even climb in bugs, when we open the smart cities, found that it was dirty. Therefore, the manufacturer's manual is required for regular cleaning
