Abstract

A liquid mixer is composed of a supporter, a motor, a gear drive mechanism and a rotator. The rotating device is composed of rollers which are supported on the bracket and are parallel to each other, the diameters of the rollers are equal, the outer layer is made of hard rubber materials, and the rotating axis of the rotating device and the geometric axis of the rotating device intersect at the same angle. The rotation directions of the rollers are consistent, and gaps are reserved between adjacent rollers. The utility model discloses utilize the synchronous rotation of each roller eccentric formula, make the tubular household utensils of arranging roller clearance department in produce continuous rotation and both ends and neglect high and neglect low repetitive movement to make blood sample or other liquid intensive mixing in the household utensils even, labour saving and time saving, it is effectual, be the ideal apparatus of medical industry diagnosis, chemical examination usefulness.

Description

The liquid vortex mixer

The utility model relates to and a kind ofly liquid is mixed the liquid vortex mixer that particularly blood sample is mixed.

Medical industry need be gathered blood sample often and chemically examines in that the patient is diagnosed, treats, and in order to obtain result of laboratory test accurately, blood sample should be mixed.At present, usually by manual, or a kind of crank throw eccentric motion device rocks the vessel that blood sample is housed, and its defective is to waste time and energy, and mixed effect is bad.

The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of time saving and energy saving, the liquid vortex mixer of good mixing effect.

Technical method of the present utility model is: the liquid vortex mixer mainly is made of support, motor, transmission mechanism, tumbler, characteristics are: transmission mechanism adopts gear drive, motion flexibility and reliability, driving gear directly are contained on the motor shaft, and the modulus of driven gear, the number of teeth equate.Described tumbler is made of the roller that is bearing on the support and be parallel to each other, each roller equal diameters, and its pivot center and geometrical axis intersect same angle [alpha]=2 °～15 °.One end and the driven gear of roller turning cylinder link, each roller rotation direction unanimity, and pivot center is positioned at same plane.

In the such scheme, roller turning cylinder and support connection place are provided with ball bearing, more flexibly, conveniently; The outer hard rubber material that adopts of roller has enough frictional force and not fragile glassware; Roller is 3～11, leaves gap 1～25mm between adjacent roller, to satisfy the needs of general operation.

The utility model utilizes the synchronous rotation of each roller centering type, make the tubular type vessel that blood sample is housed that place two roller gap locations produce rotation and two ends motion repeatedly fluctuated continuously, thereby the blood sample in the vessel is fully mixed, also can be used for the mixing of other liquid.The utility model is easy to use, and is time saving and energy saving, and rotation time can be controlled at any time, and velocity of rotation also can be regulated by changing driving gear, reaches best mixed effect.

Further specify the utility model embodiment below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation;

Fig. 2 is the gear drive schematic diagram.

Motor 3, gear drive 2, tumbler 1 are installed on the support 4, and tumbler is made of 7 rollers 6, and the point of attachment of roller and support is provided with ball bearing 5.Driving gear 7 is installed on the motor shaft, and driven gear 9 links with the turning cylinder of roller respectively, drives each roller rotation direction unanimity by idler gear 8 between the driven gear.The pivot center of roller and geometrical axis intersect same angle [alpha]=2 ° 30 '.Each roller pivot center is positioned at same plane, and geometrical axis is parallel to each other all the time, thereby guarantees the tumbler running steadily, and adjacent roller gap unanimity, and this routine intermediate gap is 4mm.The outer hard rubber material that adopts of roller has enough frictional force and can not damage glassware.The roller diameter is 30mm in the present embodiment, and length is 260mm, and rotary speed is 72rpm.
