This utility model relates to a cleaning device, including a water tank and a food cleaning tank disposed within the water tank. The food cleaning tank includes a tank body and a cleaning basket disposed within the tank body. A recessed water-passing area is provided at the bottom of the tank body, and a water-passing outlet is provided in the water-passing area. A media conveying module is disposed outside the water tank, which can be detachably connected to the water-passing outlet to facilitate water intake and / or drainage of the food cleaning tank. The aforementioned water-passing area can converge and transition the water flow, facilitating independent water intake and drainage of the food cleaning tank through the media conveying module. During water intake, this area can slowly transition the water flow to the cleaning basket above; during drainage, the water-passing area can converge and discharge the outflowing water, which is beneficial for improving drainage and removing sediment, and also helps to completely drain wastewater, achieving zero residual water in the food cleaning tank.

This invention proposes an all-steel radial truck tire tread pattern and tire, belonging to the field of tire technology. It includes multiple longitudinal main grooves extending circumferentially along the tread and multiple tread blocks separated by adjacent longitudinal main grooves. The number of longitudinal main grooves is odd, and greater than or equal to three. The top surface height of each tread block gradually decreases from the longitudinal main groove on one side to the longitudinal main groove on the other side, and the decreasing trend of the top surface height of each tread block is the same. By limiting the top surface height of the tread blocks to gradually decrease from the longitudinal main groove on one side to the longitudinal main groove on the other side, this invention significantly improves water drainage and snow removal performance, and also helps to enhance grip, longitudinal handling, and lateral anti-skid performance, thereby improving the straight-line stability of the vehicle. Furthermore, because the decreasing trend of multiple tread blocks is the same, the design is asymmetrical relative to the centerline of the tread, resulting in rigid cross-sections of the tread, further improving the straight-line stability of the vehicle on various road surfaces.
