The present application is suitable for the field of cleaning technology. The present application discloses a kind of electric scouring car tools, including electric scouring head and handle connected with electric scouring head, be equipped with for washing and collection cycle circulation water tank on the handle, the circulation water tank includes the water tank body being equipped with first cavity, the water tank body is equipped with the water inlet and outlet mechanism for water to enter or discharge first cavity, the water tank body is further equipped with the pressure relief mechanism that communicates inside and outside first cavity, the pressure relief mechanism includes the second cavity and third cavity being independently arranged with first cavity, filter screen is arranged between the second cavity and first cavity, air passage component is arranged between the third cavity and second cavity, the third cavity is communicated with exhaust nozzle communicating with outside. Since exhaust nozzle and first cavity pass through the pressure relief mechanism of second cavity and third cavity, liquid can be avoided to enter exhaust pipeline, and air discharge is not affected. Effectively release the pressure rise phenomenon generated in water tank when liquid is recycled during use.

This utility model relates to the field of film application tools, specifically to a quick film application tool for photomasks, including a base for supporting the tool. This quick film application tool for photomasks, through the arrangement of a placement seat, rubber pressure rollers, pressure rollers, and a traction plate, is driven to the bottom of the placement seat via an electric slide rail. Then, a cylinder switch is activated to push a connecting plate downwards. As the connecting plate descends, it simultaneously lowers the rubber pressure rollers, pressure rollers, and traction plate. The traction plate's descent causes its rear end to rotate outside the fixed frame, allowing it to tilt and adhere to the photomask surface. Next, a roll of film is unloaded. The roll has a film conforming to the shape of the photomask. During unloading, the bending position of the traction plate causes the film to lift and adhere to the rear side of the photomask surface. Then, as the placement seat moves, the film moves with the photomask and adheres to the surface. Afterwards, the pressure rollers compact the adhered film, and finally, the rubber pressure rollers further compact it.

This invention discloses a door leaf sealing structure, an armored door, and a door leaf manufacturing process, belonging to the field of door leaf manufacturing technology. The door leaf includes an inner panel, an outer panel, and aluminum profiles for side frames respectively disposed on both sides of the door leaf. The contact surface between the side frame aluminum profiles and the panel has a concave-convex structure, with multiple independent injection cavities on each convex surface. Each injection cavity has an injection nozzle penetrating the wall of the side frame aluminum profile for injecting sealant into the corresponding cavity. The segmented welding provides structural connection strength, while the cured sealant in each injection cavity provides sealing performance, forming a complementary combination. Each injection cavity is independent, achieving a relay-like renewal of sealing performance. The sealing quality of each side can be quantitatively verified before leaving the factory, and the sealing status can be continuously monitored during use by reading air pressure values, allowing users to visually judge the sealing status without specialized equipment.
