This application discloses an ice maker with button control, relating to the field of ice makers. It includes an ice maker body, which includes an ice dispensing seat. A mounting base is provided on one side of the surface of the ice dispensing seat. An outlet is provided on the side of the mounting base away from the ice dispensing seat, directly opposite the ice dispensing seat. An ice crushing outlet is provided inside the mounting base. The ice crushing outlet is equipped with a fixed ice crushing roller and a rotating ice crushing roller for crushing ice. A moving mechanism is provided on one side of the surface of the ice dispensing seat to drive the rotating ice crushing roller to move horizontally. The gap between the fixed ice crushing roller and the rotating ice crushing roller is adjustable by controlling the movement of the rotating ice crushing roller through the moving mechanism. By driving the rotating ice crushing roller to move horizontally through the moving mechanism, the gap between it and the fixed ice crushing roller can be flexibly adjusted, enabling the production of ice crushed of different particle sizes according to user needs, meeting diverse requirements for ice crushing coarseness in different scenarios.

This invention relates to the technical field of aseptic inoculation loops, and discloses a fully enclosed aseptic inoculation loop device, comprising a sealed box assembly, an inoculation mechanism located at the top opening of the sealed box, and a plate culture medium placed at the bottom of the inner cavity of the sealed box. The sealed box assembly includes a sealed box and a sealed door. The inoculation mechanism consists of a segmented feeding and marking mechanism, a rubber sealing cover, and an inoculation loop fixed at its lower end. The upper and lower ends of the rubber sealing cover respectively seal the inner wall of the inoculation opening and the outer wall of the vertical toothed plate. The beneficial effects of this invention are: by setting up a sealed box assembly, an inoculation mechanism, and a built-in plate culture medium, a closed aseptic working cavity is formed by the sealed box and the sealed door. The rubber sealing cover provides a comprehensive seal to the top opening of the box, completely isolating external bacteria and contaminants from entering the cavity. Structurally, this achieves a fully enclosed aseptic operation throughout the inoculation process, eliminating the problem of bacterial contamination caused by open inoculation.

The utility model relates to a heavy-load wheel-side planetary reducer which is characterized in that an input flange is connected with a fixed flange, and an input shaft is arranged in the fixed flange; the connecting flange is connected with the fixed flange, and the first double-row full roller bearing is arranged between the fixed flange and the connecting flange; the connecting flange, the flange gear ring and the rotating shell are fixedly connected; a high-speed shaft is arranged on the center shaft in the rotating shell, one end, close to the fixed flange, of the high-speed shaft is in transmission connection with the input shaft, a planetary gear train is arranged on the high-speed shaft, a gear ring is arranged on the inner wall of the flange gear ring and is in meshing transmission with the planetary gear train, and a second double-row full roller bearing is arranged between the planetary gear train and the rotating shell. The planetary gear train is used for supporting the rotary shell under rolling friction; a plurality of deep groove ball bearings are arranged between the planetary gear train and the input shaft and between the planetary gear train and the high-speed shaft and used for supporting the planetary gear train. The utility model has the advantages that the radial load bearing capacity is effectively improved; heating is reduced, and transmission efficiency is improved; and the hub reduction requirement under the heavy-load working condition is met.
