Improved structure for preventing backflow suction pipe

This creation relates to an improved structure for preventing backflow suction tubes, especially for the purpose of facilitating replacement of the diaphragm to reduce bacteria at the diaphragm.

According to water, water is one of the main components of the human body. It is often excreted in different ways by sweat, excretion, respiration and evaporation. Therefore, we must add a lot of water every day, especially when going out for work, outings or sports. Under the constant activity of the sun and the body, the body loses water more quickly. When it feels dry, it is a warning that the body has insufficient water content, that is, it needs to be replenished at the right time to maintain the water balance in the body. Nowadays, the water bottle or water is filled. The containers are of different styles, mainly containing liquids for drinking at home or on the go. In order to make it easier for drinkers to drink, the liquid in the water bottle can be sucked more smoothly through a straw inserted in the water bottle. After the liquid is sucked, when the mouth leaves the straw, the liquid that has previously sucked up the mixed saliva flows back into the container, resulting in a hygienic problem that easily breeds bacteria.

Therefore, some related companies have made research and improvement on this deficiency. For example, the new patent No. M435431 of the Republic of China on August 11, 101, "The structure of the suction tube structure for preventing backflow" discloses a structure improvement of the suction tube. a sucking seat and a straw portion, the sucker seat is provided with a suction portion, and the suction portion is provided with an opening valve, and the suction portion is The rear end of the seat is provided with a set of connecting holes, a front end of the connecting hole is provided with a pivoting hole and extends inwardly, and the suction pipe portion is combined and clamped; and the suction portion is provided with an opening valve for sucking Prevent liquid from flowing back into the container during the liquid to reduce the hygiene problems of bacterial growth.

However, as far as the above is concerned, there is a problem in that the sucking portion of the sucking seat is used for the user to drink liquid, and the valve of the sucking portion controls the flow of the liquid, and when the user's mouth leaves the sucking portion, The valve of the sucking portion is closed to prevent the liquid from flowing back into the container. However, after a period of use, the valve of the sucking portion is also damaged, and the effect of preventing backflow is lost, and the bacteria are caused to be generated at the valve. It is easy to cause the user's disease, which is a big drawback in the use, and needs to be improved.
