The invention can cause the evaporating liquid to evaporate through the temperature change in the cabinet, drive the fan blades to rotate to dissipate heat, and the fan blades rotate to throw out the insect repellent liquid in the liquid storage tank, drive away the mosquitoes at the vents, and prevent mosquitoes from entering the power distribution cabinet cause short circuit damage to the device.

The invention discloses a baby crib toy frame which is easy to assemble and disassemble and adjust, which comprises a baby crib body. Both ends of the baby crib body are fixed with fan-shaped mounting plates, and the bottom of the fan-shaped mounting plate is fixed with an auxiliary baby crib shaking The swing device used, the outside of the fan-shaped mounting plate is equipped with a detachable pole assembly that facilitates the installation of mosquito nets, assists babies to sleep and provides toys. The present invention directly installs the detachable pole assembly on the fan-shaped mounting plate to achieve The direct installation of the mosquito net is simple and convenient. At the same time, through the cooperation of the swing device and the detachable pole assembly, the body of the baby bed can be blown automatically, which improves the baby's summer sleep quality and has the effect of repelling insects. Using the rotating plate to rotate, It drives the inclination of the center of gravity on the fan-shaped mounting plate, assists the body of the crib to shake, does not need artificial shaking, and is more convenient for the baby to fall asleep.

The invention discloses a membrane-coated drug-loaded microsphere, which uses microcrystalline cellulose, organic calcium, and sodium bis(2-ethylhexyl)succinate sulfonate as a pore-forming agent for macroporous silicon. Obtain mesoporous or hollow or three-dimensionally penetrated porous silica, and then undergo acidification treatment with hydrochloric acid to dissolve and remove the calcium in the silicon-calcium skeleton to obtain macroporous and three-dimensionally penetrated porous silica, and the porous silicon skeleton and The surface is very rough, and the pits and grooves are very rich, which is conducive to the adhesion of drug loads. And the film-coated drug-loaded microspheres are used to prepare drug sustained-release insect repellent pet collars, and the obtained pet collars have good insect repellent effects, long-term sustained-release effects, and good quality preservation effects. The technology of the product of the invention is mature, the production operation is simple and easy to understand, and the production cost is relatively reasonable.

The invention relates to a method for making, preserving and identifying individual specimens of non-toxic rainbow trout and perch specimens. The method includes the preparation process, preservation and individual identification of specimens. Fix the fish in a designed motion state and make a fish head model; wrap the entire surface of the specimen with plastic wrap, pour the prepared gypsum into the container, and after the gypsum solidifies, divide the solid gypsum into multiple pieces and take out the fish specimen Put the solid gypsum together, inject foaming material into it, make the shape of the fish specimen, and take out the fish model; choose the side or abdomen of the fish according to the display method to make an incision, and peel off the skin; degrease the skin of the fish, and remove the skin Put it into water dissolved with washing powder, remove the grease on the surface, then degrease with acid clay and sawdust, and air dry; install the fish skin and fish head model on the fish model. The method for preparing specimens of rainbow trout and perch provided by the invention has no physical damage to specimen preparation personnel and visitors.

The novel outdoor tent disclosed by the invention canplay an insect repellent effect and reduce a phenomenon of mosquito bites.

The invention discloses a cave-type mountain area forest protecting hut and belongs to a cave-type building in the building field. The main body of the hut is a cave excavated on the side wall of a mountain body; a moisture-proof and heat preservation wall is arranged on the inner wall closely attached to the cave; a door plate is arranged at an entrance of the cave; and the moisture-proof and heat preservation wall is of a multi-layer structure and is provided with an aluminum alloy layer, an adobe layer, a litter layer, a detritus filling layer and a plank layer sequentially from the inner wall closely attached to the cave to outside. The cave-type structure is adopted, the heat preservation effect of being cool in summer and warm in winter is achieved, the composite structure formed by the aluminum alloy layer, the adobe layer, the litter layer, the detritus filling layer and the plank layer is adopted to serve as the wall, not only is the damp characteristic of the cave changed, but also the heat preservation characteristic is further strengthened, and infestation of harmful organisms such as snakes, insects and ants is prevented.
