The invention discloses an ozone sterilizing ventilation shoe, which is composed of a miniature ozone generator system installed in an ordinary shoe body (heeled shoes or flat shoes). The ozone generator system is composed of honeycomb elastomer pedal air pump, air inlet and outlet accessories, rechargeable battery, piezoelectric transformer type high-voltage generator circuit and control circuit, ceramic ozone generator, control switch and other main parts. When walking with shoes on, use the power generated by the heel to compress or relax the honeycomb elastic body pedal air pump to complete the function of supplying or exchanging air from the ozone source. Turn on the power to generate ozone; turn off the power, as long as you walk, the function of ventilation still exists. The invention is a practical health-care shoe that prevents and treats athlete's foot with the shoe, eliminates foot odor, ventilates and dehumidifies and keeps the inside of the shoe dry.

The invention relates to the technical field of protective devices, and discloses a VR fitness sports helmet with good ventilation function, the VR fitness sports helmet comprises a protective helmet,the top of the protective helmet is fixedly connected with a support rod, and the top end of the support rod is fixedly connected with a protective plate. The sports helmet with the good ventilationfunction for VR fitness has the advantages that the ventilation function is good; by installing the protection plate, air hole can be covered, rainwater is prevented from entering the protective helmet from the air holes; a good rainproof effect can be achieved; by arranging a filter screen, mosquitoes can be prevented from entering the protective helmet from the air holes; the effect of protecting the head is achieved; by arranging a buffering inner layer, the protective helmet can be prevented from making direct contact with hair, ventilation and air permeability are better, meanwhile, external force can be buffered, damage caused by the external force to the head is reduced, when the face needs to be protected by goggles, rainwater is prevented from entering the sports helmet, the headis protected, and the head of an athlete is prevented from being wetted by the rainwater.

The invention discloses inner wall decoration mortar, which is mixed by the following components in part by weight: 8 to 15 parts of common silicate cement, 3 to 4 parts of slaked lime, 3 to 5 parts of light aggregate, 4 to 6 parts of negative ion aid, 70 to 80 parts of heavyweight aggregate (wind-carried sand) and 1.0 part of composite aid, wherein the light aggregate is an inorganic vitrified hollow cellular material with thickness of lower than 100 meshes. The decoration mortar is environment-friendly, natural, long-acting and stable, has the advantages of prominent three-dimensional texture, good decoration effect, good grain composition, small heat conducting coefficient and reduced heat bridge effect, effectively prevents the inner wall from cracking, hollowing and dropping, and is favorable for mechanized construction; and the decoration mortar can eliminate indoor unclean and harmful substances, purify the air, continuously keep the indoor air fresh and promote human health bycontinuously generating negative ions. The inner wall decoration mortar is diluted by water in an amount which is 30 to 50 percent of the weight of the mortar and then is mechanically coated or manually constructed.

The electric shower head has excellent cleaning effects and can beautify the skin.

The invention discloses a temperature-keeping, ventilating and energy-saving dry-method structure of a slope roof and a construction method thereof. The structure comprises a cement mortar leveling layer, a waterproof cushion layer, a temperature-keeping and draining layer, cross roof wood battens and roof tiles, wherein the temperature-keeping and draining layer consists of temperature-keeping plates, supporting wood brackets, longitudinal downstream wood strips and aluminum foil coil materials; the supporting wood brackets are arranged on the waterproof cushion layer; the temperature-keeping plates are fully paved on the waterproof cushion layer; the temperature-keeping plates are clamped between the supporting wood brackets; the longitudinal downstream wood strips are pressed on the temperature-keeping plates; the aluminum foil coil materials are paved on the longitudinal downstream wood strips and are fixedly connected with the longitudinal downstream wood strips through nails; the aluminum foil coil materials, the longitudinal downstream wood strips and the temperature-keeping plates enclose to form a longitudinal airtight air layer. The structure has the best advantages of very good heat-insulating ability and good temperature-keeping and energy-saving property, the heat conductivity of the roof can be effectively adjusted, and the energy-saving effect of a house can be greatly improved.

The invention discloses a pitched roof mounting system for a solar thermal collector and a construction method of the pitched roof mounting system. The system comprises a pitched roof and the solar thermal collector arranged on the pitched roof, wherein the pitched roof consists of a structural layer, a cement mortar leveling layer, a waterproof pad layer, a heat preservation water drainage layer, transverse tile hanging wood bars and roof tiles, wherein the heat preservation water drainage layer consists of a heat preservation plate, wood carrying brackets I, longitudinal downstream wood bars and an aluminum foil coiled material; two-side concave-shaped water drainage ditches are formed between the solar thermal collector and the longitudinal downstream wood bars on the left side and the right side of the solar thermal collector; an upper-side concave-shaped water drainage ditch is formed between the solar thermal collector and transverse lap-joint wood bars; a lower-side concave-shaped water drainage ditch is formed between the solar thermal collector and the roof tiles on the lower side of the solar thermal collector. According to the system and the construction method which are disclosed by the invention, the construction technology is changed; the solar thermal collector can be firmly and stably mounted; the pitched roof has energy-saving and ventilating effects; the heat insulation and preservation efficiency of the pitched roof can be improved, and the surface of a building is attractive.

The invention belongs to the technical field of household appliances, in particular to an indoor and outdoor ventilator for a balcony. Aiming at the problems of poor dust filtering effect and inconvenient cleaning of the filter structure of the existing ventilator, the following proposal is proposed, including the main frame, the The inside of the main frame is provided with a rectangular cavity, and two rotating shafts are connected between the top inner wall and the bottom inner wall of the rectangular cavity through bearings, and the two rotating shafts are respectively close to the inner walls on both sides of the rectangular cavity, and the two rotating shafts are mutually The adjacent sides are all connected with mounting plates by bolts. In the present invention, when the air flows through the net frame, the activated carbon filter screen inside the net frame can adsorb pathogens and odor molecules in the air, so as to improve the purification effect in the ventilation process of the device. The dust-collecting fluff can bind and trap tiny floating ash particles and bacteria in the air, further improving the purification effect of the device during the ventilation process.
