The invention relates to an anti-fogging self-cleaning laparoscope which is characterized in that a transparent glass sheet is fixedly arranged at the outer end of an objective lens at the far end of the laparoscope, and a closed carbon dioxide gas groove is formed in a gap between the transparent glass sheet and the objective lens; an air inlet pipeline is fixed along the inner wall of an outer tube of the laparoscope, a corresponding air inlet hole is formed in the near end of the air inlet pipeline, and the far end of the air inlet pipeline penetrates through the objective lens and extends into the carbon dioxide gas groove; a gas outlet pipeline is fixed along the inner wall of the outer tube of the laparoscope, the far end of the gas outlet pipeline extends into the carbon dioxide gas groove, and the near end of the gas outlet pipeline exhausts gas through a gas exhaust hole; and the air inlet is externally connected with a carbon dioxide air source. The laparoscope solves the technical problems that an existing laparoscope is prone to causing fogging of an objective lens and infection of tissue fluid in a minimally invasive abdominal surgery, consequently, the surgical field is blurred, and surgical operation needs to be interrupted due to the fact that a real-time processing function does not exist.

The invention belongs to the field of sand mills, and particularly relates to a sand milling structure for grinding water-based paint raw materials, a using method and a sand mill. The sanding structure for grinding the water-based paint raw materials comprises a grinding cylinder, a grinding rotating disc arranged in the grinding cylinder, a feeding pipe arranged on one side of the grinding cylinder and a discharging pipe arranged on the other side of the grinding cylinder, and the grinding rotating disc is of a rod pin type or turbine type structure; a plurality of jet exciters are arranged in the inner wall of the grinding cylinder, and a one-way water inlet pipe is connected to an excitation cavity of each jet exciter and used for injecting cleaning fluid into the excitation cavity in the cleaning stage. The jet flow exciter is integrated on the inner wall, in direct contact with materials, of the grinding cylinder, so that the same structure has the dual functions of actively enhancing flow field disturbance during grinding and high-pressure directional flushing during cleaning, and integration of grinding efficiency improvement and equipment self-cleaning is achieved.

This utility model relates to the field of cleaning device technology, and provides a steam boiler inner wall flushing and cleaning device, including a base plate; a support seat is installed on the upper end of the base plate, a bracket is installed on the top of the support seat, and a fixed shaft is rotatably installed on the top of the bracket. The steam boiler inner wall flushing and cleaning device provided by this utility model allows for adjustment of the distance between the brush plate and the fixed shaft by pulling up and down the connecting sleeve during use. When encountering a boiler with a small opening, the brush plate can be placed close to the fixed shaft and then removed. This device adapts to various boiler sizes through flexible adjustment of the brush plate position, thereby effectively improving its applicability. Water in the water tank is pumped to the fixed shaft and sprayed onto the inner wall of the boiler from the spray nozzles on the surface of the fixed shaft. This design allows for precise flushing of the boiler's inner wall, thereby improving the cleaning effect of the device.

The utility model provides a vegetable weeder, belongs to weeder equipment technical field, the vegetable weeder includes shell, motor, shaft and weeding blade group, the shell is used for placing motor, shaft and weeding blade group, the motor is placed on the inside one side of shell, the output shaft is fixed connection with shaft, the inside of shaft is hollow structure, and the shaft is equipped with the weeding blade group. The side wall is fixedly connected with the weeding blade group, the weeding blade group is used for removing weeds, and a plurality of water outlet holes are formed in the center of the weeding blade group on the side wall of the rotating shaft and used for removing soil impurities adhered to the weeding blade group; one side of the rotating shaft is fixedly connected with the motor, the other side of the rotating shaft is rotationally connected with the water inlet, and the rotating shaft is rotationally connected with the water inlet through a rotating joint; the vegetable weeding machine blade can solve the problem that the blade is not easy to clean after being used, and is convenient to clean.

The application discloses a test tube cleaning device for chemical laboratory, and relates to the field of laboratory equipment. The top of the base is provided with a water tank; the supporting rod is vertically arranged on the top of the base; the lifting assembly is arranged on the side wall of the base; the supporting plate is sleeved on the outer wall of the supporting rod and is connected with the output end arranged on the lifting assembly; the connecting block is arranged on the end of the supporting plate away from the supporting rod, the bottom of the connecting block is communicated with the spray pipe, and the side wall of the connecting block is connected with the water pipe of the external water source; the two clamping assemblies are symmetrically distributed on the two sides of the center line of the water tank, one end of the clamping assembly is fixed to the base; the two clamping blocks are arranged on the free ends of the two clamping assemblies, and the area between the two clamping blocks is used for clamping the test tube. The application effectively solves the problems that the traditional test tube cleaning cannot be positioned and the water outlet position of the faucet is difficult to adjust, can flexibly adjust the height of the spray pipe according to the specifications and pollution conditions of the test tube, accurately positions the test tube, performs efficient cleaning, and reduces the cleaning difficulty and labor intensity.

This utility model relates to a spray head assembly for a washing machine, belonging to the field of washing machine technology. It includes a spray head body and a water flow adjustment mechanism installed on the outside of the spray head body. A spray hole is provided at the bottom of the spray head body. The water flow adjustment mechanism includes a miniature electric push rod rotatably mounted on the outside of the spray head body, a movable rod fixed at the bottom end of the miniature electric push rod, and a conical block located at the bottom end of the movable rod and directly below the spray hole. This utility model utilizes the extension and retraction of the miniature electric push rod to drive the conical block up and down. When the conical block moves upward, it approaches the spray hole and disperses the water flow, facilitating the washing of thin clothing. As the conical block and other components continue to move downward, guided by a first and second triangular plate, the conical block is pushed open from below the spray hole, allowing the spray hole to directly spray water onto thick clothing. Overall, by adjusting the spray head's rinsing range, more precise cleaning can be achieved for different types and materials of clothing, improving the cleaning effect.
