Cleaning brush for electric heating tubes of water distilling apparatuses

Abstract

The invention discloses a cleaning brush for electric heating tubes of water distilling apparatuses. The cleaning brush comprises a brush. The brush is of an arc-shaped structure, brush balls with connecting rods are arranged on the front surface of the brush and are uniformly mounted on the brush via the connecting rods at intervals, bevel transmission teeth are connected with the tail ends of the connecting rods of the brush balls, rollers which correspond to the connecting rods of the brush balls are further arranged on the front surface of the brush, the rollers and the connecting rods of the brush balls are distributed in a staggered manner, 1 / 4-1 / 3 part of each roller is exposed outside the brush, the rollers are connected with the corresponding bevel transmission teeth by bevel gears, and the axes of the bevel transmission teeth, the rollers and the bevel gears are fixed into the brush; back brushes are arranged on the back surface of the brush. The cleaning brush has the advantages that the special brush balls and the special rollers are arranged on the brush, the brush balls can be driven by the rollers to rotate, accordingly, the heating tubes can be comprehensively cleaned by the brush balls in multiple directions and can be omni-directionally cleared up without dead spaces by the brush balls and the rollers, the clear-up efficiency can be guaranteed, the labor intensity of clear-up work can be relieved to a great extent, and the clear-up time can be shortened; the cleaning brush is simple in structure and low in cost, and good service effects can be realized.

Description

technical field [0001] The invention relates to the technical field of experimental instruments, in particular to a cleaning brush for an electric heating tube of a distilled water appliance. Background technique [0002] A water distiller is an instrument that uses electricity to heat tap water to produce pure water, and is widely used in various laboratories. The water distiller is mainly composed of three parts: a condenser, an evaporating pot, and an electric heating tube. The main material is made of stainless steel sheet and stainless steel seamless tube. The electric heating part adopts the immersion electric heating tube. This part is at the bottom of the evaporating pot. The electric heating tube is immersed in the water to heat, so that the water boils to obtain steam. Since tap water contains more minerals such as calcium (Ca) magnesium (Mg) salts, it will be decomposed in boiling water and will become insoluble calcium carbonate (CaCO 3 ) and magnesium hydroxi...

Problems solved by technology

However, even so, due to the scale cleaning of the electric heating tube, it is still difficult to clean completely due to its special structure.
