Technical Field

The invention relates to a water filtering device, in particular to a cup with a filtering function.

Background

The existing water cup does not have a filtering function, so that great inconvenience is brought to field workers. For this reason, a cup with a filtering function has been proposed in the prior art, and is referred to as "ultrafiltration cup" in patent No. ZL201020639711.0 (publication No. CN201879328U), which includes: the filter membrane wire is fixed on the base, the inner container is movably sleeved in the shell, the outer wall of the inner container is provided with a sealing ring, the base of the filter membrane wire is connected to the bottom of the inner container, and the lower part of the base is movably connected with a primary filter device; the upper end of the inner container is movably connected with a sealing cover with a handle. The bottom of the shell is provided with an emergency bottom valve. When in use, the inner container is taken out, the shell is filled with water to be treated, the inner container is inserted into the shell, and the inner container is forcibly extruded downwards. At the moment, the water is pressurized and can enter the container of the inner container through the primary filter device and the filter membrane filaments at the bottom of the inner container to obtain clean filtered water

Although the cup disclosed in the above-mentioned document can obtain filtered water, the design has the following disadvantages: firstly, when the liner is inserted into the shell, the sealing ring on the outer wall of the liner plays a role in sealing to prevent water flow from flowing out of the outer wall of the liner, the sealing ring is directly sleeved on the inner wall, the liner is difficult to insert and pull every time, and the sealing ring is easy to displace, wear and deform, so that the sealing property is reduced; secondly, the sealing cover is arranged on the port of the inner container, if the sealing performance of the sealing cover is good, when the inner container is inserted into the shell for water purification, air in the inner container is compressed, the air pressure is increased, and water is not easy to enter the inner container from the bottom; if the sealing performance of the sealing cover is poor, water in the inner container is easy to leak out when the sealing cover is used accidentally.
