Description

Technical Field

[0001] The invention relates to the technical field of water purification, and in particular to a handheld outdoor ceramic water purifier. Background Art

[0002] Water is the source of life and the basic element of human beings and all other living things. Adequate drinking water resources are the most basic conditions for ensuring outdoor quality of life and physical health. When a disaster occurs or when you are doing outdoor activities, although there is sufficient water around, most of them cannot meet the standard of safe drinking. Therefore, it is a good choice to use a portable ultrafiltration device that can filter surface water into drinking water during outdoor activities and emergency rescue. However, the existing handheld water purifier device has a complex structure, poor integration, and needs to be disassembled and cleaned.

[0003] For example, the Chinese utility model patent with announcement number CN214167562U discloses "an outdoor emergency water purification device", which includes a main body, a ceramic membrane filter element located in the main body, a detachable water outlet, a manual piston water inlet device and a water inlet device. The filtering effect is achieved by arranging a microfiltration membrane tube and a central layer filled with metal cluster water purification filter material, adsorption filter material and antibacterial material in the ceramic membrane filter element. The ceramic membrane filter element is cleaned with a detachable water outlet. The ceramic filter element in the device is difficult to clean. If it is blocked, it needs to be disassembled and cleaned frequently. In addition, the device is large in size and the overall shape is not ergonomic, and it is not convenient to hold with both hands.

[0004] In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art: the water purifier needs to use a variety of materials for the filter element to filter, sterilize and disinfect different pollutants, which makes the device complicated; the piston rod and the filter element take up a large space, resulting in a larger overall device; when the filter element is contaminated and clogged, it needs to be disassembled and cleaned, which can easily reduce the life of the filter element and make operation difficult.
