  • Patent number: 11963651
    Abstract: An autonomous cleaning device and a noise reduction air duct device are provided for autonomous cleaning device. The autonomous cleaning device includes a body and a motor arranged on the body, and the noise reduction air duct device is mounted on the body. The noise reduction air duct device includes an upper housing, a lower housing and a support noise reduction structure made of elastic material. The lower housing and the upper housing enclose to form an air duct, an air inlet is arranged at a position of the air duct corresponding to the motor, and an air outlet is arranged on a side of the air duct away from the air inlet; the support noise reduction structure has a first end fixed on the lower housing, and a second end abutting against a lower surface of the upper housing.

  • Publication number: 20230260773
    Abstract: The present disclosure provides a method for constructing a correlation model between relative bioavailability and bioaccessibility of cadmium in earthworm, belonging to the technical field of cadmium detection in earthworms. The method includes the following steps: determination of relative bioavailability of cadmium in earthworms, determination of bioaccessibility of cadmium in the earthworm based on an in vitro physiologically-based extraction test (PBET) method, and construction of a correlation model between the relative bioavailability and the bioaccessibility of cadmium in the earthworm. The method enables to directly put the bioaccessibility obtained by the in vitro method into a regression equation to obtain the bioavailability of cadmium in subsequent studies.
