Special shower

Abstract

A special shower consists of a rotation portion and a fixed portion. The fixed portion comprises a base, an electric motor B and a rotary shaft of the electric motor B. The base is a hollow bucket-shaped body and is thin in upper portion and thick in lower portion. The electric motor B is installed inside the base, the rotary shaft of the electric motor B extends out of the upper portion of the base, and the central axis of the rotary shaft coincides with the symmetrical axis of the base. The rotation portion comprises a rack, an electric motor A, an inner threaded rod, an outer threaded rod, a piston, a bucket, a water outlet pipe, a spray head turning mechanism, a spray head, a showering bucket and a water collecting bucket. The electric motor A is installed at one end of the rack, a shaft of the electric motor A is connected with the inner threaded rod, the inner threaded rod is meshed with one end of the outer threaded rod, the other end of the outer threaded rod is connected with the piston, and the piston is inserted into the bucket and can perform reciprocating motion in the bucket. The open position of the bottom of the bucket is connected with the water outlet pipe, the water outlet pipe is connected with the spray head turning mechanism, and the spray head which can be turned is installed on the spray head turning mechanism. The spray head can be aligned to the showering bucket through turning. The showering bucket is in a shape of a hollow circular truncated cone, the larger bottom face of the circular truncated cone is close to the spray head, and the other bottom face is movably connected with the top of the water collecting bucket. The top of the water collecting bucket is an outer concave circular cone, and a middle opening serves as a water inlet of the water collecting bucket. The special shower has the advantages that an astronaut can have a shower like showering on the earth, and water drops automatically fall from a human body and do not cause choking; water for showering is always flowing water, and dirty water is discharged out in time; the astronaut can have a shower for the whole body rather than head exposure in the outside; a function of spin-drying water left on the body after showering is provided.

Description

technical field [0001] The invention relates to a space shower. Background technique [0002] Astronauts who perform space missions need to live in space for a long time. For example, Russian cosmonaut Sergei Vasilyevich Avdeyev, who has lived in space for the longest time, is the first time in space. Stayed for 189 days, stayed in space for 178 days for the second time, and stayed in space for 378 days for the third time. If you live in space for such a long time without taking a shower, the astronauts will inevitably have peculiar smells, and the cabin space is small and airtight, and the persistent smell is even more unbearable. Therefore, bathing is an indispensable part of astronauts’ space life. missing part. [0003] Bathing in space is a hassle. The water in the state of weightlessness is small drops of water, which can easily choke and injure people or even choke them to death. Therefore, the usual way for astronauts to take a bath is to wipe their bodies with we...

Problems solved by technology

There are two obvious disadvantages in this kind of space bathroom. One is that the astronauts are always soaked in dirty water mixed with bath liquid and human body dirt during the bathing process, and the longer the bathing time, the dirtier the bath water; the other is that the head must be exposed outside of the bag, so only wash below the neck
