Description

Technical Field

[0001] The utility model relates to a portable manual water purifier, belonging to the technical field of water purifiers. Background Art

[0002] Water purifiers are mainly devices used in households. A large amount of existing technology research focuses on water purifiers in the kitchen, such as the water purifiers installed in kitchen cabinets that we use frequently in daily life, which filter tap water to provide drinking water.

[0003] However, with the improvement of people's living standards, how to solve the drinking water problem in the wild during self-driving tours? Some solutions for portable water purifiers are given in the existing technology. For example, CN202320719210.0 discloses a portable water purification device, including a water purification cup body. A limiting shell is fixedly installed on the right inner wall of the water purification cup body. A water purification component for purifying water is arranged on the surface of the water purification cup body and the surface of the limiting shell. Among them, a limiting shell 2 is fixedly installed on the right inner wall of the water purification cup body 1. A water purification component 3 for purifying water is arranged on the surface of the water purification cup body 1 and the surface of the limiting shell 2. A top cover component 4 is arranged on the top of the water purification cup body 1. A lower cover 5 is threadedly inserted at the bottom of the water purification cup body 1. A pressurizing mechanism 6 for pressurizing the inside of the water purification cup body 1 is arranged on the left side wall of the water purification cup body 1; the water purification component 3 is inserted into the inside of the water purification cup body 1 and the surface of the limiting shell 2. Water is added to the inside of the water purification cup body 1 through the top cover component 4. The top cover component 4 includes a cover body 401 threadedly inserted at the top of the water purification cup body 1. An inlet 402 is arranged on the top of the cover body 401. An outlet 403 is arranged on the top of the cover body 401. An outlet pipe 404 is inserted and installed on the top of the limiting shell 2, and the bottom end of the outlet pipe 404 is located inside the limiting shell 2. Through the inlet 402, it is convenient to add and fill water into the inside of the water purification cup body 1. Through the outlet 403 and the outlet pipe 404, it is convenient to suck the purified water. This device meets the requirement of portability, but it is not beautiful enough, has a small water capacity, and its filtration depends on a plugged-in water purification component, so the filtration ability is limited.

[0004] Moreover, for a water purification device, there may be many application scenarios, such as installation and use in ordinary families, use in emergency situations such as earthquakes or floods, and use in outdoor camping. It is difficult to meet all these scenarios. Moreover, different application scenarios require different structures. In the prior art, for example, the portable water purifier disclosed in JP2004234054 is equipped with a suitcase, which consists of a waterproof shell body that can be used as a water container and a lid that can be opened and closed on the shell body. The inside of the lid is equipped with a filtration device for bathing water, river water, and rainwater to purify dirty water into drinking water, and also a pump unit that absorbs the dirty water contained in the main body and sends it to the filtration device. Among them, when using the box structure, the pivotally connected upper lid needs to be opened, and the structure is too large and cumbersome. Compared with the above-mentioned water purification cup body, the water purification capacity is much greater than the former, but there is a problem of being too cumbersome.
