Abstract

The utility model discloses an electric test tube brush. The electric test tube brush is provided with a handheld part, wherein a power supply unit is arranged in the handheld part; a motor which stops rotating when bearing axial pressure is arranged on the front part of the power supply unit; a connecting rod which drives a brush head to rotate at high speed is connected to the front part of the motor in a detachable mode; and the front end of the connecting rod is connected with the brush head. Due to the adoption of the technical scheme, the electric test tube brush is simple in structure, can be used for cleaning a test tube quickly and can effectively avoid the condition that the test tube is broken due to overlarge force. As the electric test tube brush is simple in structure, the electric test tube brush can be produced conveniently, is low in cost and is particularly suitable for wide popularization.

Description

Electronic test-tube brush

Technical field

The utility model relates to international monopoly Main classification A46 brush based article, relates in particular to other brush classes of A46B15/00; The brush class that attachment device is arranged.

Background technology

In the chemical experiment process, the use of glasswares such as test tube, beaker, conical flask is absolutely necessary, and can conveniently carry out for experiment next time, and we needed liquid residual on its inwall or sediment are cleaned when experiment finished.The test-tube brush that generally uses at present is to be made up of brush holder and brush; Brush holder is that an iron wire congeals into long-time use like a hen on a hot girdle; When glassware is scrubbed in the laboratory, need hand to hold rotary manipulation before and after the brush, and used brush need be corresponding with the model of scrubbing vessel when scrubbing, this method of operating extremely bothers effort; Also brush breaks the vessel bottom especially easily, hurts the physical impairment test-tube brush of oneself.The electronic test-tube brush that occurs on the market has now replaced craft to clean with micromotor; But also the brush that can change different models cleans; Reach the purpose of power saving that saves time, but for this brush, the experimenter is under scatterbrained situation; Still may exert oneself excessive and then glassware bottom is damaged, cause unnecessary loss.

Summary of the invention

The utility model is to the proposition of above problem; And a kind of electronic test-tube brush of developing; Have the grip part, this inside, grip part has power supply unit, and the front portion of this power supply unit is provided with and receives the motor that axial compressive force is stopped the rotation; Anterior removable being connected with of this motor drives the connecting rod that brush rotates at a high speed, and the front end of said this connecting rod is connected with brush.

Said brush and connecting rod are releasable connection.

Be provided with spring between said motor and the power supply unit; The place ahead of said motor, grip part inwall are provided with at least 2 stopping means that are used to limit motor position, and said stopping means connects the two poles of the earth of power supply unit; The positive and negative electrode that the front end of said motor matches with said stopping means.

Said stopping means is a static contact, and this static contact is a conductor.

Because the electronic test-tube brush that adopted technique scheme, the utility model to provide has been realized through a kind of simple structure, clean tube fast, and can effectively avoid owing to overexert, and poke test tube.Because it is simple in structure, not only be convenient to produce, and cost is very cheap is suitable for extensive popularization.

Description of drawings

Technical scheme for clearer explanation embodiments of the invention or prior art; To do one to the accompanying drawing of required use in embodiment or the description of the Prior Art below introduces simply; Obviously, the accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is the cutaway view of the utility model

Among the figure: 1. grip part, 11. power supply units, 12. motors, 13. springs, 14. stopping means, 2. connecting rod, 21 brushes.

The specific embodiment

For the purpose, technical scheme and the advantage that make embodiments of the invention clearer; Below in conjunction with the accompanying drawing in the embodiment of the invention; Technical scheme in the embodiment of the invention is known complete description; Obviously, described embodiment is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to protection scope of the present invention not making all other embodiment that obtained under the creative work prerequisite.

Embodiment 1

As shown in Figure 1: a kind of electronic test-tube brush, have grip part 1, promptly lever is hold by one hand this part during use, and the shaft portion appropriateness is goed deep into test tube, inner getting final product.1 inside, grip part has power supply unit 11, and is preferred, and this power supply unit 11 adopts No. 5 powered battery of single-unit.The front portion of power supply unit 11 is provided with baffle plate, and the front portion of baffle plate is connected with spring 13, and the front end of spring 13 is connected with motor 12; The front of motor 12; On the inwall of grip part 1, be provided with at least 2 static contacts 14, static contact 14 connects power supply unit 11, is equivalent to the power supply to motor 12 power supplies.

During inactive state, motor 12 receives that the effect of spring 13 and static contact 14 is in the dynamic balance state.When connecting rod 2 receives axial compressive force; Power passes to spring 13 through motor 12, when this power when making spring 13 that elastically-deformable minimum force take place, spring 13 begins compression; Drive the displacement that motor 12 produces backward; Motor 12 separates with static contact 14, and promptly motor 12 can't obtain electric energy, stop motion.When connecting rod 2 was diminished by axial force, spring 13 recovered shape, pushing motor 12 and static contact 14 joints, and motor 12 regains electric energy, works on.

The above; Be merely the preferable specific embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field is equal to replacement or changes according to the technical scheme of the utility model and inventive concept thereof in the technical scope that the utility model discloses, and all should be encompassed within the protection domain of the utility model.
