The armrests and the backrest of the sofa are integrally formed so that no seams can be generated, it is avoided that dust falls into seams, and convenience is brought to daily use and cleaning of the sofa; the rotating base is arranged on the lower portion of the sofa body, so that the sofa conveniently rotates in use; the lighting device and the reading device are arranged on the two sides of the sofa body respectively, so that a user convenientlyreads on the sofa without the need for a reading table, and in the cooperation of the lighting device in use, the sofa is specially suitable for reading at night and reading in a place low in light.

The invention relates to the technical field of wood floor cutting and discloses a wood floor dustproof cutting device used for home decoration. The wood floor dustproof cutting device comprises a fixing frame. The left end of the interior of the fixing frame is rotationally connected with a cutting piece, and a transverse plate is fixedly installed at the right end of the interior of the fixing frame. A water groove body is fixedly installed in the right end of the transverse plate, and a piston cylinder is fixedly installed at the upper end of the water groove body. A piston rod is connectedin the piston cylinder in a sliding manner, and a tooth plate is movably connected to the upper end of the piston rod. A first clamping plate is connected to the upper end of the fixing frame in a sliding manner. By means of the wood floor dustproof cutting device used for home decoration, an inflation device is composed of the piston cylinder and the piston rod, a rotating handle drives a threaded rod to rotate, the threaded rod drives a gear to rotate and then is matched with the gear to drive the tooth plate to move, inflation and deflation of an air bag are achieved, in addition, due to the effect of a hole, dust can be sucked into the water groove body in the cutting process, and the effect of dust falling is achieved.

The invention discloses a cyclone dust collector used in the process of harmless treatment of diseased animals. The outer wall of the cylinder is provided with an air inlet, the upper end of the cylinder is connected with a head, and the head of the head is The upper part is provided with a pipe that runs through the cylinder, the upper end of the pipe is provided with an air inlet, the upper part of the inner wall of the pipe is provided with a fine mesh, and the lower part of the fine mesh is provided with a coarse mesh that is close to the inner wall of the pipe. The bottom of the cylinder is connected with the conical cylinder, and the bottom of the conical cylinder is provided with a dust collection port. In the present invention, coarse and fine filter screens are arranged at the air outlet. After the high-temperature steam containing material dust particles undergoes first-level dust reduction treatment in the equipment, the coarse and fine filter screens set at this position can realize secondary filtration when it is discharged through the air outlet. treatment, the efficiency of dust removal is really improved, the operation stability is strong, the problem of pipeline blockage in the next process caused by incomplete treatment is eliminated, and the efficiency of harmless treatment is improved.

The invention belongs to the field of dust falling and environmental protection, and provides a rapid replacement device suitable for a dust falling nozzle on a mine continuous mining machine. The invention relates to a nozzle core assembly and a nozzle holder. The nozzle core assembly is composed of a nozzle core 1, a hexagon nut 2, a rubber gasket 3 and a fastening pin 5. The two ends of the fastening pin 5 are placed in the corresponding L-shaped groove channels in the nozzle base 4, installation of the nozzle is completed through clockwise screwing, and disassembly is completed through anticlockwise screwing. The fastening pin penetrates through the nozzle core, the nozzle core assembly is tightly connected with the nozzle seat 4, and the nozzle core is prevented from loosening and falling off due to mechanical vibration or external force. And the rubber gasket 3 is used for preventing the nozzle core and the nozzle seat from directly contacting to cause abrasion at the contact part, and also plays a sealing role. The whole device is made of stainless steel materials, and corrosion is prevented. The device has the advantages that a matching structure of the nozzle and the nozzle holder is designed, so that quick mounting and dismounting are realized when the nozzle is replaced, and the device is time-saving, efficient and reliable.

The invention discloses a glass fog residue dust falling device for plain glass cutting and an implementation method thereof, and belongs to the technical field of plain glass cutting. The glass fog residue dust falling device comprises an operation table, a supporting frame is installed on the operation table, a transverse cutting mechanism is installed on the supporting frame, plain glass is arranged below the transverse cutting mechanism, and the plain glass is placed on a machining table; and a glass fog slag dust falling mechanism is arranged on the side surface of the plain glass. According to the glass fog residue dust falling device for plain glass cutting and the implementation method of the glass fog residue dust falling device, plain glass is cut through the transversely-moving and rotating cutting blade, the glass fog residues can be adsorbed and collected to achieve the dust falling purpose, the fog residues generated in the cutting process are not likely to harm the physical and psychological health of operators, and the environment cannot be polluted; a good working environment is created for plane glass cutting, dust residues can be screened in a classified mode, recycling of the dust residues is facilitated, resources are saved, and when the dust residues are screened in the classified mode, dust falling is achieved through atomization of the water mist nozzles, and environmental protection is achieved.
