The invention discloses a process for preparing a V2O3 / ZnV2O3 total battery by simultaneously using vanadium oxide in a zinc ion battery as a positive electrode material and a negative electrode material, which comprises the following steps: reacting ammonium metavanadate with absolute ethyl alcohol by adopting a solvothermal synthesis method, washing, drying, and calcining in a tubular furnace to obtain V2O3; in the preparation process of the V2O3 positive electrode material, only V2O3, acetylene black serving as a conductive agent and PVDF serving as a binder are mixed in proportion and then are coated on graphite paper, other coating protection materials do not need to be introduced into a V2O3 / Zn negative electrode, and V2O3 is used as a protection layer to inhibit growth of zinc dendrites, relieve hydrogen evolution side reaction of the zinc negative electrode and reduce corrosion of zinc. Vanadium oxide V2O3 is directly used as a core positive electrode material, the zinc negative electrode coating is developed by utilizing the characteristics of the vanadium oxide V2O3, a material is formed, meanwhile, the performance optimization of the positive electrode and the negative electrode is realized, the used raw materials are simple and easy to obtain, the process is simple and easy to implement, and the preparation process is simple and easy to implement from V2O3 raw material synthesis to positive and negative electrode piece preparation to V2O3 / ZnV2O3 total battery assembly. And comprehensive improvement of positive and negative electrode performances of zinc ions is simultaneously realized by a single material.

The utility model provides a flosser belongs to flosser technical field, it has solved the present flosser existence health hidden danger's technical problem. The flosser includes box body and ejector, and the box body has floss outlet, and the box body has the transverse baffle in, and the upper side of transverse baffle has the strip hole who arranges along the moving direction of ejector, and the ejector includes the baffle and the moving seat who forms from the downward protruding of the lower side of baffle, and the moving seat supports in the upper side of transverse baffle, and the moving seat has the hook portion who stretches out the strip hole downward, and the flosser is equipped with the elastic member who can make the moving seat to the side where floss outlet is located translation, and the top wall of box body has the let -by hole who is through, and the baffle is along the strip hole length direction and is set to strip shape, and the upper side of baffle is in close contact with the top wall of box body, and the baffle's middle section has the protruding portion who protrudes the let -by hole. The flosser has better health protection effect.

This utility model provides a medicine box, including a base and a connecting cover disposed above the base and rotatable in a circumferential direction along the base. The base is hollow to form a cavity for containing medicines. The base is provided with a partition plate to divide the cavity into several medicine storage chambers. The connecting cover is provided with a through groove that can be opposite to any medicine storage chamber. The connecting cover is also provided with a sealing block for covering the through groove. A cover plate is also provided above the connecting cover, which can close with the base. This medicine box can overcome the defect of the prior art where the cover is easy to loosen after being rotated many times over a long period of time, which may cause the cover to rotate on its own when not in use, causing the medicine inside the medicine box to fall out.
