The invention discloses a water cup for police. The cup comprises a base, a shell, a filter mechanism, a second cover body and a lifting handle. The shell is of a cylinder structure which is coaxial with the base and is connected with bearings, and the circumstance surface of the shell comprises an inner layer and an outer layer; the filter mechanism comprises a foundation, a first cylinder, a second cylinder and multiple filter layers which are placed between the first cylinder and the second cylinder; the second cover body can be in threaded connection with the upper end of the inner layer,and a piston is connected to the interior of the second cover body through a retractable rod; the lifting handle comprises a second rod body and two third rod bodies which are fixedly arranged at thetwo ends of the second rod body. The water cup for police is simple in structure and convenient to carry, a water source can be quickly and efficiently filtered to obtain drinkable clean water, and the water cup has high economical practicability.

Description

technical field [0001] The invention relates to the technical field of police equipment. More specifically, the present invention relates to a police drinking cup. Background technique [0002] As the source of human life, water plays an irreplaceable role, but water pollution is becoming more and more serious. 70% of the rivers and lakes in our country are polluted to varying degrees, and the drinking water of more than 300 million people is unsafe. For police officers, it is often necessary to go to the field to perform duties. When police officers stay outdoors for a long time, they often have insufficient drinking water. In extreme natural disaster emergency situations, due to limited conditions, police officers cannot The wild water source is completely clean before drinking. It cannot effectively isolate bacteria, ions and other substances harmful to the human body in the water. It is easy to cause illness after drinking water, and endanger life safety in severe case...

Problems solved by technology

For police officers, it is often necessary to go to the field to perform duties. When police officers stay outdoors for a long time, they often have insufficient drinking water. In extreme natural disaster emergency situations, due to limited conditions, police officers cannot The water source in the wild is completely clean before drinking. It cannot effectively isolate bacteria, ions and other harmful substances in the water, which may easily cause illness after drinking water, and endanger life safety in severe cases.

[0003] Existing police water cups do not have the function of filtering outdoor water sources. Although some of the existing ordinary water cups have filtering functions, the structure of the internal filtering mechanism is relatively complicated, the manufacturing cost is high, and it cannot meet the needs of outdoor emergency water filtration. ; In addition, the existing police water cup is only used as a water storage tool, and does not have other incidental life-saving functions, which has a single function and less practicability
