Abstract

The invention discloses a conveniently-heated beaker, comprising a beaker body; a rabbet is formed in the upper side edge of the beaker body; an end cover is arranged at the upper end of the beaker body, a through hole is formed in the end cover, and a stirring rod is arranged in the through hole; an arc-shaped groove is formed in the bottom end face of the beaker body; a heating metal sheet is arranged on the lower end face of the arc-shaped groove, and the shape of the heating metal sheet is matched with that of the lower end face of the arc-shaped groove; a plurality of metal connecting rods are arranged on the upper end face of the heating metal sheet; an internal metal sheet is arranged in the arc-shaped groove, and the shape of the internal metal sheet is the same as that of the heating metal sheet. The conveniently-heated beaker has the advantages that the beaker can overcome the disadvantages of the prior art, and is reasonable and novel in structural design.

Description

technical field [0001] The invention relates to a convenient heating beaker, which belongs to the field of teaching equipment. Background technique [0002] A beaker is a common laboratory glassware, usually made of glass, plastic, or heat-resistant glass. The beaker is cylindrical with a notch on one side of the top for easy pouring. Some beakers are also marked with scales, which can roughly estimate the volume of liquid in the beaker. When the existing beaker is used for classroom teaching demonstration, because the heat source of classroom teaching generally adopts alcohol lamp, but the heat of alcohol lamp is low, and the heat source is not concentrated, thus resulting in slow heating speed, making the time of classroom demonstration too long, affecting the teaching progress. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a beaker which is convenient for heati...
