The invention discloses a feces collector of a bedsore-preventing intelligent nursing machine. The feces collector comprises a feces collecting device and a control device, wherein the feces collecting device comprises a wearing part and a body attaching part, the body attaching part comprises elastic air ring cushions or an air ring cushion group and an air charging pipe, the elastic air ring cushions are attached on the wearing part, the air ring cushion group consists of more than two elastic air ring cushions in an alternate air exhaust way, the air charging pipe is conducted with the air ring cushion and is connected with the control device, the other ends of the air ring cushions are also connected with the control device, the single air ring cushion is arranged in the inner side of the edge of the outer contour of the wearing part, the air ring cushion group consists of an upper air ring cushion and a lower air ring cushion, the upper air ring cushion and the lower air ring cushion are communicated, and the orientations of the air exhaust openings of the upper air ring cushion and the lower air ring cushion are crossed. The faces collector solves the technical problem that the ventilation performance is improved, and meanwhile the bedsore forming of the pressed part of a patient due to unsmooth blood circulation is avoided.

The invention belongs to the field of construction, and in particular relates to a summer balcony window with a dimming function, which includes an outer frame, and the outer frame is provided with two pieces of outer glass and inner glass that are both vertically arranged, and the inner glass The upper end of the inner wall is fixedly connected with a handle, the inner top surface of the outer frame is provided with an upper fixing groove, and the inner bottom surface of the outer frame is provided with a lower fixing groove, and the upper and lower edges of the outer glass and the inner glass are fixed by the upper and lower edges respectively. The mechanism and the lower fixing mechanism are movably connected with the upper fixing groove and the lower fixing groove. In the present invention, when the outside light intensity is strong in summer, during the process of pulling the inner glass inward, the flexible plate, the elastic ring, the hard plate, the hard ring and the elastic connecting ring will jointly form a concave lens, which can not only pass through the inner glass The water absorbs the heat of the sun, and because of the principle of astigmatism of the convex lens, it can also disperse the incident light, avoiding the hot summer sun from concentrating on a certain area of ​​the balcony and causing the skin of the wall and floor tiles on the balcony to peel and fade.

The invention provides a pressure electric organ, the electricity power of which is generated by compressive movement on the ground during human walking. The invention also provides a power generation shoes under pressure of electronic components lines for rectification, charging, energy storage and lighting. The power generation shoes under pressure comprise a pressure electric organ, a bridge-typed whole wave rectification reactor, a electrolytic capacitor, a rechargeable battery, a light emitting diode, a power switching, a power socket and a shoes. The pressure electric organ used in the power generation shoes under pressure at least comprises two flexible magnetic cores, two coils, a permanent magnet, a elastic device, a permanent magnet guiding groove, a pressure transmission plate and a coil frame. The invention is a power-generating device with no mechanical transmission system, no noise and no requirement for lubrication.
