Abstract

The utility model provides an electric test-tube brush with adjustable rotating speed. The electric test-tube brush comprises a hair brush, a shell, a double-throw switch, a small motor, a high-voltage power supply and a low-voltage power supply; the double-throw switch is arranged on the shell; and the small motor is arranged in the shell. The electric test-tube brush is characterized a loop is formed by the motor and each of the high-voltage power supply and the low-voltage power supply via the double-throw switch; threads are arranged at an end of an output shaft of the motor; a brush handle of the hair brush is made of rubber; a nut is fixed at an end of the brush handle; and the brush handle is connected with the output shaft via the nut in a threaded manner. The test-tube brush can be disassembled and assembled, components of the test-tube brush can be replaced, so that the problem that the total test-tube brush is declared worthless due to the fact that a certain component is worn down is avoided, and the service life of the electric test-tube brush is long. When the electric test-tube brush works, the suitable rotating speed of the motor is selected by the double-throw switch according to apertures of test tubes and surrounding environments, so that experimental instruments in chemical laboratories are cleaned, the problem that chemical reagent residual liquid in the test tubes splashes can be avoided, and the electric test-tube brush is convenient to operate, safe in use and high in work efficiency.

Description

The electronic test-tube brush of rotating speed adjustable

Technical field

The utility model relates to a kind of electronic test-tube brush of rotating speed adjustable, belongs to the brushing tool technical field.

Background technology

The brush of the glass cleaning laboratory apparatus of laboratory use now; Majority is that brush holder, brush rod and bristle connect together, in case wherein any part is impaired, just causes whole test-tube brush not use again; Significantly reduced the service life of test-tube brush, this is a huge waste; And when cleaning test tube with test-tube brush, chemical reagent residual in the test tube much has corrosivity; When cleaning test tube, majority be afraid of the chemical reagent in the test tube splash own or other people on one's body, that scrubs usually is very slow; Lose time very much, and also be a huge test muscle power.

The utility model content

The purpose of the utility model provides and a kind ofly can overcome that above-mentioned defective, easy to operate, safe in utilization, life-span are long, the electronic test-tube brush of the rotating speed adjustable of high efficiency.Its technical scheme is:

A kind of electronic test-tube brush of rotating speed adjustable; Comprise hairbrush, shell, be arranged on the commutator on the shell and miniature motor, high power supply and low power supply in the enclosure is set; It is characterized in that: high power supply and low power supply constitute the loop through commutator and motor respectively, and the end of the output shaft of motor is provided with screw thread, and the brush holder of hairbrush adopts rubber to process; The end of brush holder is fixed with nut, and brush holder is threaded with output shaft through nut.

The utility model compared with prior art, its advantage is:

1, utilize commutator and high power supply, low power supply to cooperate, can select suitable rotating speed according to size, the surrounding environment in test tube aperture, avoided chemical agent residue liquid in vitro advance to spatter;

2, brush holder adopts rubber to process, and has better elastic and serviceability;

3, test-tube brush can be dismantled, assemble, and parts can be changed, and avoids causing scrapping of whole test-tube brush, long service life because of a certain parts loss.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment.

Among the figure: 1, hairbrush 2, shell 3, commutator 4, motor 5, high power supply 6, low power supply 7, output shaft 8, brush holder 9, nut

The specific embodiment

In the embodiment shown in fig. 1: commutator 3 is arranged on the shell 2; Be provided with miniature motor 4, high power supply 5 and low power supply 6 in the shell 2, through commutator 3 and motor 4 formation loops, the end of the output shaft 7 of motor 4 is provided with screw thread respectively for wherein high power supply 5 and low power supply 6; The brush holder 8 of hairbrush 1 adopts rubber to process; Have enough elasticity, the end of brush holder 8 is fixed with nut 9, and brush holder 8 is threaded with output shaft 7 through nut 9.
