The invention relates to a washing machine and a washing method. The washing machine comprises an inner barrel, an outer barrel and solid particles as washing medium. The inner barrel is rotatably arranged on the inner side of the outer barrel, an air channel is arranged in the washing machine, the air channel is communicated with the inner barrel to form an air flowing path, an air thruster is arranged on the air flowing path, and a baffle with a plurality of open holes only enabling the particles to pass through is arranged on the position of an air flowing outlet inside the inner barrel. The air flowing path is formed in the air channel and the inner barrel by utilizing the air thruster, the particles are pushed to flow along the direction of the flowing of air, and therefore throwing-in, separating and recovering of the particles are achieved, and not only is the process of the separating and the recovering of the particles simplified, but also a washing process is simplified.

The invention discloses a rapeseed oil squeezing device capable of collecting rapeseed oil conveniently. The rapeseed oil squeezing device comprises a main body, a pumping plate, a flow guiding plateand a sliding rod. A hydraulic cylinder is arranged above the main body, a hydraulic rod is arranged below the hydraulic cylinder and penetrates through the main body, and a pressing plate is arrangedbelow the hydraulic rod. The pumping plate is arranged above the main body and clamped into a slideway, and meanwhile, the slideway is formed in the inner side wall of the main body. An open hole isformed in the surface of the bottom of the pumping plate, and a bottom plate is arranged above the bottom of the pumping plate and clamped into a groove. Meanwhile, the groove is formed in the surfaceof the bottom of the pumping plate, and a supporting plate is arranged above the bottom plate and connected with the bottom plate through a filter net. A movable plate is arranged in the middle of the supporting plate. According to the rapeseed oil squeezing device capable of collecting the rapeseed oil conveniently, the pressing plate and the open hole are formed, the hydraulic cylinder can drive the hydraulic rod and the pressing plate to ascend and descend, and the pressing plate can squeeze rapeseeds in the bottom plate and the supporting plate.

The invention relates to a concreted filled steel tube composite pile and a manufacturing device and method thereof. The concreted filled steel tube composite pile comprises a steel tube, a reinforcing tube, a connection unit and concrete, wherein the steel tube is longer in the vertical direction and is internally vertically through; a hollow hole is formed in the reinforcing tube; the reinforcing tube is arranged inside the steel tube; the connection unit comprises a single board arranged on the lower portion of the steel tube and a lateral board upward from the periphery of the single board and can be connected with other piles; the concrete is poured into the space formed by the inner surface of the steel tube, the outer surface of the reinforcing tube and the inner surface of the connection unit; the lower end of the reinforcing tube is fixed to the single board; an open hole is formed in the position, corresponding to the reinforcing tube, of the single board, so that the open hole and the hollow hole of the reinforcing tube are communicated. The connector portion of the composite pile is stable in structure, the bending resistance is greatly enhanced, the structure is simple, manufacturing is easy, and therefore the manufacturing expense is reduced.

A naked-eye 3D lens display device and a method for manufacturing the same are disclosed. The present disclosure relates to the technical field of 3D display, and particularly to a naked-eye 3D display technology. The technical problem that the lens of the display device in the prior art cannot be switched between 3D display mode and 2D display mode can be solved. The two electromagnetic shielding films are arranged facing each other. The frame and spacers are arranged between the two electromagnetic shielding films, and the frame and spacers and the two electromagnetic shielding films form a closed space. The electronically controlled magnetic poles are respectively arranged on two inner walls of the electromagnetic shielding films facing each other. The liquid medium is distributed in the closed space. The transparent magnetic particles are arranged in the liquid medium in the closed space. The display screen is fixed on an outer wall of either of the two electromagnetic shielding films. The beneficial effect lies in that, the naked-eye 3D lens can be switched between 3D display mode and 2D display mode. The 3D lens display device is light and thin, and has a good display effect and a low cost. The naked-eye 3D lens can be used in 3D display products.

The invention discloses a double-port tube of a transfusion bag. The double-port tube comprises a tube body seat, a transfusion tube and a feeding tube, wherein the transfusion tube and the feeding tube are arranged side by side and vertically fixed on the same surface of the tube body seat; vertical through holes are formed in the transfusion tube and the feeding tube; one end, fixedly connected with the tube body seat, of each through hole is of flat rhombus, the other end of the through hole is round, and the middle of the through hole is in transition from roundness to flat rhombus; and the tube body seat is provided with two flat rhombic open holes communicated with the through holes in the transfusion tube and the feeding tube. According to the double-port tube of the transfusion bag, the transfusion tube and the feeding tube are separated, so that cross contamination when medicinal liquid is used is avoided; and one end of each through hole is of flat rhombus, so that the material is saved, and the production cost is reduced.

The present invention discloses a compound-structured keypad of the mobile communication terminal which belongs to the scope of the mobile communication terminal components and is comprised by multiple keys. It includes: the keyboard assembly, whose back side is inserted by multiple convex keys that integrated to one body, the front side is exposed by the open hole which is formed at the external shell of the mobile communication terminal; the bracing member of the key, which is provided with multiple plug-in holes which are corresponding to the inserting pump of the multiple keys, make the keyboard assembly insert to the inner side of the shell in the mobile communication terminal and fix it. The invention not only improves the operating character, furthermore, the joint of the keypad is stronger than the joint of the mobile communication terminal. It can avoid the phenomenon of twist of the key-compound keypad or the falling from the mobile communication terminal which are caused by the falling of the mobile communication terminal and colliding to the ground or the impact by other reasons.
