End is fixed with hemispheric cleaning shell 19;Cleaning 19 inner wall bottom side of shell is fixed with iron prop 20;The outer wiper mechanism includes bottom
Seat 21, side neck 27 and top cylinder 28;Middle part in pedestal 21 is fixed with permanent magnet 22;21 upper end of pedestal is fixed with cleaning sponge 23;
The upper center setting fluted 24 of cleaning sponge 23;Each 9 lower end of support rod is respectively fixedly connected with the positioning being obliquely installed
Bar 25;25 lower end of locating rod is fixedly connected with the brush board 26 for the arc being vertically arranged;26 bilateral symmetry of brush board of the left and right sides is set
It sets;Brush board 26 is below side neck 27;The end of branch cleaning axle 15 is fixedly connected with side neck 27, and branch cleaning axle 15 is in side neck 27;
Pushing up cylinder 28, Open Side Down, and top cylinder 28 is sleeved and fixed the top for being mounted on cleaning axle 10;The opposite surface of two brush boards 26
For inner surface;The surface of upper cleaning axle 10, the surface of crankshaft 11, the surface of branch cleaning axle 15, lower cleaning axle 16 surface, clear
The outer surface of clean shell 19, the inner surface of brush board 26, side neck 27 inner surface and push up cylinder 28 inner surface be uniformly arranged respectively
There is bristle 29;Lower cleaning axle 16 is to be plugged and fixed to connect with the lower end of crankshaft 11;Brush board 26 and 25 lower end of locating rod are solid for grafting
Fixed connection;The lower end of pedestal 21 is equipped with sucker 30.
In the use of the present invention, tool test tube is plugged on interior wiper mechanism and (removes Zhi Qingjie by taking tool test tube as an example
Axis 15), brush board 26 and test tube shape cooperate, and have gap between two brush boards 26, and the branch pipe of tool test tube may pass through, and make have branch examination
It is entered at the top of pipe in the cylinder 28 of top, 11 position of crankshaft and branch pipe are substantially aligned, and magnetic ball 13 is directed toward branch pipe, clean 19, shell
In bottom in test tube, tool test tube is contacted by the package of bristle 29 of top cylinder 28, brush board 26 or after can rotating at this time, internal also equal
It can be contacted after contacting or rotate with the bristle 29 of inside, then side neck 27 is installed, side neck 27 is socketed in branch pipe periphery, branch cleaning axle
15 penetrate out of branch pipe, using 13 magnetic butt joint base 14 of magnetic ball, realize the flexible connection of interlocking lever 12 and branch cleaning axle 15, bottom
Seat 21 can fixed placement (when chemical experiment, basin is typically provided with by laboratory table) in basin, at this time complete installation.Cleaning behaviour
Work is completed in basin, and basin supplies water and distilled water provides clean water.
When being cleaned, power mechanism provides power, and operator holds handheld housing 1, opens driving motor 2 and works,
It drives connecting shaft 5 to rotate, is cooperated by the transmission of transmission gear 7 and driving gear 8, driving gear 8 and 5 rotation direction of connecting shaft
On the contrary, the cleaning in outside turns on the contrary, effectively realizing that relative motion is cleaned i.e. in test tube.Simultaneously by test tube bottom and cleaning
(pressure contact with cleaning sponge 23 can also play certain anti-rotation positioning action to test tube, make up positive and negative rotation the contact of sponge 23
Form the inconsistent situation of relative friction), and make a relative move and to form relative friction cleaning, bottom outside cambered surface is carried out clear
It is clean, and moved in the form of relative translation, change scrub face contact, while in order to change permanent magnet 22 and iron prop 20
Relative position drives iron prop 20 to change position by magnetic, thus drive cleaning shell 19 in vertical direction there are rolling transposition,
By rotor plate 18 and switching ball 17 turning set connect in succession, cleaning shell 19 can realize around the heart adjusting rotation (rotational angle compared with
There is cleaning dead point in the small center of rotation position that can avoid), and still rotational power can be carried out by the frictional force of rotation socket place
Transmission.When cleaning the vertical adjustment of shell 19 and horizontally rotating mixing, dead point more can be effectively avoided the occurrence of.
When crankshaft 11 is rotated, by 12 structure of interlocking lever of rotation connection, the reciprocal of branch cleaning axle 15 can be driven
Movement, to be cleaned to the surfaces externally and internally of the branch pipe of tool test tube.The main body and branch pipe of tool test tube are carried out simultaneously clear
Clean, cleaning effect is more preferable, avoids causing the pollution to other cleaning parts when cleaning respectively using sequencing.
Bristle 29 is contacted with tubing surfaces to be cleaned, itself has certain deformation behavior, meanwhile, in the present invention, brush
Hair 29 itself need to have certain support elasticity capacity, support force is capable of forming after extrusion deformation, in order to be formed with to test tube
The clamping position of effect (general bristle 29 can also have enabling capabilities after squeezing accumulation).The bristle of each position is not emphasized in description
29 specific structure etc., according to different location, can be used unlike material, length, hardness, density, direction bristle 29, according to reality
Border situation and common sense can judge.It is emphasized that bristle 29 can be used inclination outward and stretch out in some junctions
Form, colliding with when guaranteeing covering, while avoiding relatively moving between device, such as at branch pipe, side neck 27 and brush board 26
And the position between the cylinder 28 of top, for example in the corresponding peripheral position of rotation connection of cleaning shell 19, vertically adjusted in cleaning shell 19
It need to guarantee the covering of bristle 29 when section rotation, can guarantee effectively covering by forms such as outer oblique, raising density, avoid the occurrence of scarce
Leakage.Bristle 29 has done simplified processing in attached drawing.
The uniform bristle 29 in 15 surface of branch cleaning axle also plays position-limiting action to branch cleaning axle 15, avoids movement of colliding with.For
The restriction for improving the motion profile of branch cleaning axle 15 can additionally be socketed the limiting bracket for increasing rubber material, make branch cleaning axle 15
Under the drive of crankshaft 11, the reciprocating motion with branch pipe coaxial direction is done, while can have the appearance of lesser upper and lower displacement again
Perhaps variable can generate upper and lower displacement in order to whole, change the contact form of bristle 29, improve cleaning effect.
The friction lines for the settable longitudinal in 17 surface of ball of transferring increases horizontal direction resistance, and rotation of improving the standard passes
Dynamic stability, and vertical adjusting rotation is influenced smaller.
The present invention is also applicable to some common test tubes, when installation, takes out branch cleaning axle 15 and side neck 27, crankshaft
Bristle 29 on 11 is equally able to carry out the annular surface covering of corresponding position when rotating.To avoid connecting rod from colliding, using normal
The positioning means of rule are fixed, and avoid random whipping, for example utilize adhesive tape bonding etc..
The settable battery case of 1 internal upper part of handheld housing and battery are powered, the settable handheld housing of the switch of driving motor 2
1 appropriate location.
