Description
Technical field
The invention belongs to articles for daily use technical field, be specifically a kind of portable 360 degree without dead angle normal pressure or space environment mesh screen and application.
Background technology
Existing home-use sieve is mostly Unseal type, the movement range large or flour multiple spot a little that once sieves when compass screen surface powder, and the flour just easy open-mouth from sieve spreads out, and in screening process, sieve aperture is easy to be blocked by oarse-grained flour, in screening process, can be got more and more by the mesh blocked, major part mesh is blocked after death, screening can only be stopped, material in sieve is taken out, then sieve is overturn after vibration, the flour blocking mesh just can drop, and mesh just can be dredged; Or directly will block the mesh screen cleaning of mesh, flour will be washed, but any method process that don't work, the flour blocking mesh is often wasted.
At ordinary times in family expenses or scientific experimentation, when needs carry out three timesharing to granular material, just necessarily use two mesh screens of different meshes mesh, a people takes two mesh screens, often attends to one thing and lose sight of another, therefore, also want two people to cooperatively interact and just can carry out screening, coordinate bad, often have powder and scatter, cause unnecessary waste.
Due to the complexity that space environment requires, in space, often seldom be with powder or band to sieve the powder handled well, but the scientific experimentation of routine always needs screening materials carrying unavoidably and uses mesh screen, but existing open mesh screen due to material during vibration can comprehensive splashing and can not using.
China Patent Publication No. CN104959306A, publication date 2015.10.07 patent document discloses a kind of efficient spherical screening machine, comprise base, housing assembly, screening assembly.Described housing assembly comprises joint pin, supporting plate, recovering hopper, support spring, and described recovering hopper is placed in the top of described supporting plate.The lower end of described joint pin is fixedly connected with described supporting plate, and described supporting plate is connected with described base by described support spring.What this application solved is the problem of screening machine to the screening effeciency of stone, and spherical be integral structure, be not easy to unpick and wash, due to volume too large (can not fold), carry also inconvenient.
