Electronic analytical balance capable of conducting self-cleaning

Abstract

The invention relates to an electronic analytical balance capable of conducting self-cleaning. The electronic analytical balance capable of conducting self-cleaning comprises a measuring pedestal and a measuring room arranged on the measuring pedestal, and further comprises a cleaning room also arranged on the measuring pedestal; the cleaning room is composed of an ultrasonic cleaning device and a drying device; the ultrasonic cleaning device is composed of an ultrasonic generator, an ultrasonic transducer and a detergent spraying device; the drying device is arranged in the measuring room, wherein the drying device comprises an electric heating tube; the electric heating tube extends from the cleaning room into the measuring room. According to the technical scheme, the effect that a measuring table of the electronic analytical balance and the surface of an object to be measured do not have dirt is ensured, so that a more accurate measuring result can be obtained; meanwhile, the electric heating tube is used for heating the inside of the measuring room, residual detergent on the measuring table and the object to be measured can be evaporated rapidly, measuring errors are reduced, and the inside of the measuring room also can be kept dry so as to prevent humid air from affecting measuring data.

Description

technical field [0001] The invention relates to a balance, in particular to a self-cleaning electronic analytical balance. Background technique [0002] As a precision measuring tool, electronic analytical balance has been widely used in industry, medical treatment, chemical industry and other fields. Since the object to be measured of an electronic analytical balance has extremely high requirements on measurement accuracy, the slightest error in the measurement process may affect the measurement result. The electronic analytical balance will inevitably leave more or less dust and dirt on its surface during long-term use, and it is difficult to clean the surface of the object to be measured during the production and transportation process; the above-mentioned dirt may affect the measurement results of the balance to be tested , and simple scrubbing is usually difficult to remove dirt. Contents of the invention [0003] The technical problem to be solved by the present in...
