Description

Technical Field

[0001] The utility model relates to the technical field of dry ice cleaning machines, in particular to a dry ice cleaning machine with a nozzle protection structure. Background Art

[0002] Dry ice cleaning machine is a type of cleaning machine. Dry ice cleaning has been developing rapidly around the world. The cleaning system uses high-pressure air to spray dry ice particles from the dry ice cleaning machine onto the work surface to be cleaned. The physical reaction of temperature difference is used to make different substances separate at different shrinkage speeds, thereby achieving a fast, efficient, safe and energy-saving cleaning effect.

[0003] Publication No. CN214865829U discloses a dry ice cleaning machine that is easy to move and fix, including a machine body, a front rotating shaft is rotatably connected to the bottom surface of the machine body near the front of the machine body, a front rotating rod is installed at the bottom end of the front rotating shaft, front rollers are symmetrically sleeved at both ends of the front rotating rod, and a front connecting rod is symmetrically installed on the outer side of the front rotating shaft. A rear rotating shaft is slidably embedded in the top surface of the machine body near the back of the machine body, and a rear connecting rod is symmetrically installed at the bottom end of the rear rotating shaft penetrating the machine body. The front connecting rod and one end of the rear connecting rod on the same side of the machine body are hinged through a connecting rod, and the front connecting rod can be driven to rotate by rotating the steering rod, which directly drives the front roller to steer the cleaning machine, thereby avoiding the problem of poor control of the rotation due to the excessive weight of the machine body. The dry ice cleaning machine is convenient for moving the cleaning machine, and by stepping on the brake pedal, the brake pads can be squeezed to squeeze the rear rotating rod to slow down the moving speed of the machine body, so as to avoid the inertia pulling the staff when the machine body is moved, causing danger to the staff. Although the dry ice cleaning machine can make the brake pads squeeze the rear rotating rod to slow down the moving speed of the machine body by stepping on the brake pedal, it is more stable during deceleration and has a good deceleration effect, so as to avoid the inertia pulling the staff when the machine body is moved, but the dry ice cleaning machine needs to use a spray gun during operation. The nozzle part of the dry ice cleaning machine spray gun lacks a protective structure. When the nozzle is collided, it is easy to cause the nozzle to deform or the internal components to be damaged, resulting in the nozzle being unable to spray dry ice, affecting the use of the staff, and needs to be improved.
