Description

Technical Field

[0001] The invention relates to the field of medical equipment and laboratory instruments, and in particular to a novel mini mixer. Background Art

[0002] The mini mixer is an instrument used for laboratory liquid mixing or solid-liquid mixing. It is suitable for oscillating and mixing a small amount of samples. It can be used to oscillate test tubes, centrifuge tubes, eppendorf tubes, etc. The basic working principle of the mini mixer is to use the eccentric oscillation effect of the eccentric wheel to make the test tube produce a vortex and fully mix the reagents.

[0003] Almost all existing mini mixers use a round silicone cap as a shaking seat. The shaking seat is easily rotated relative to the main shell when it is covered on the main shell. At the same time, due to the periodic centripetal pulling force of the eccentric wheel, the main shell and the whole machine body vibrate obviously, the noise is loud, and even "running" occurs, affecting the experimental operation and oscillation effect; and the existing mini mixer lacks a working indicator light, which cannot clearly indicate the working status of the machine to the operator. At the same time, due to the unsatisfactory foot pad structure, there are defects such as poor shock absorption effect and loud noise. For this reason, we propose a new mini mixer. Summary of the invention

[0004] The purpose of the present invention is to overcome the problems of the existing mini mixer, such as the relative rotation between the shaking seat and the main shell, obvious shaking of the whole machine, no working status indication, loud noise and easy "running". A nearly triangular shaking seat with a buffer groove and a working indicator light are provided, which can effectively solve the problems of relative rotation between the shaking seat and the main shell, obvious shaking or "running" of the whole machine, loud noise and no working status indication, improve the experience and convenience of using the mixer, improve the effect of oscillation mixing, and improve the safety of the whole machine, so as to solve the problems raised in the above background technology.

[0005] To achieve the above purpose, a new mini mixer includes a body, the upper end of the body is plugged with a shaking component, the bottom of the body is fixedly installed with a shock absorbing component, and the interior of the body is fixedly installed with a display component and an instrument body component:

[0006] The shaking assembly comprises a shaking seat, a shaking seat buffer groove and a shaking seat buckle, wherein the shaking seat buffer groove is provided at the center of the upper surface of the shaking seat, and the shaking seat buckle is fixedly connected to the lower surface of the shaking seat;

A wear-resistant gasket is sleeved at the bottom of the motor output shaft. The top of the motor output shaft is also fixedly connected with an eccentric wheel. The upper end of the eccentric wheel is fixedly connected with a deep groove ball bearing. The outer wall of the deep groove ball bearing is fixedly connected with a support protection cap. The outer wall of the support protection cap is inserted into the center of the lower end of the shaking seat.

[0010] Preferably: The shaking seat is made of silica gel material, and a round hole adapted to the size of the test tube is opened at the center of the upper surface of the shaking seat.

[0011] Preferably: The number of the double-layer sucker feet is not less than three, and the vertical cross-section of the double-layer sucker feet is arranged in a wavy structure.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1-6 , the figure shows a preferred embodiment of the present invention, a new type of mini mixer, including a body 10, a shaking component 20 is inserted and connected to the upper end of the body 10, a shock absorption component 30 is fixedly installed at the bottom of the body 10, and a display component 40 and an instrument body component 50 are fixedly installed inside the body 10:

[0035] The shaking component 20 includes a shaking base 21, a shaking base buffer groove 22 and a shaking base buckle 23. A shaking base buffer groove 22 is opened at the center of the upper surface of the shaking base 21, and a shaking base buckle 23 is fixedly connected to the lower surface of the shaking base 21;

[0036] The shock absorption component 30 includes a base 31 and a plurality of double-layer suction cup feet 32. The base 31 is fixedly connected to the bottom of the body 10, and the plurality of double-layer suction cup feet 32 are fixedly installed around the center of the lower surface of the base 31 on the lower surface;

[0037] The display component 40 includes a circuit PCB board 41, a micro switch 42 and an indicator light 43. The circuit PCB board 41 is fixedly connected to the inner wall of the body 10, a micro switch 42 is fixedly connected to the outer wall of the circuit PCB board 41, one end of the circuit PCB board 41 is fixedly connected to an indicator light 43, and one end of the indicator light 43 extends out of the outer wall of the body 10.

[0038] As Figures 1-6 shown, the instrument body component 50 includes a brushless motor 52, a motor output shaft 53, a wear-resistant gasket 54, an eccentric wheel 55, a deep groove ball bearing 56 and a support protection cap 57. The brushless motor 52 is fixedly connected to the upper surface of the circuit PCB board 41. A motor output shaft 53 is vertically rotatably connected to the middle of the brushless motor 52. A wear-resistant gasket 54 is sleeved at the bottom of the motor output shaft 53. An eccentric wheel 55 is also fixedly connected to the top of the motor output shaft 53. A deep groove ball bearing 56 is fixedly connected to the upper end of the eccentric wheel 55. The outer wall of the deep groove ball bearing 56 is fixedly connected to a support protection cap 57, and the outer wall of the support protection cap 57 is inserted into the lower end center of the shaking base 21.

[0039] The material of the shaking base 21 is silicone material, and a round hole adapted to the size of the test tube is opened at the center of the upper surface of the shaking base 21.

[0040] The number of double-layer suction cup feet 32 is not less than three, and the vertical cross-section of the double-layer suction cup feet 32 is arranged in a wavy structure.

[0041] The cross-section of the shaking seat 21 is approximately triangular. The upper surface of the fuselage 10 is fixedly connected with a main fuselage shell, and a card slot is opened on the outer wall of the main fuselage shell. The size of the card slot is adapted to the size of the shaking seat buckle 23.

[0042] The number of indicator lights 43 is not less than one, and the micro switch 42 is located below the wear-resistant gasket 54.

[0043] The vertical cross-section shapes of the fuselage 10 and the shaking seat 21 are approximately columnar structures that shrink from bottom to top. A DC power socket 11 is fixedly connected to the outer wall of the fuselage 10.

[0044] The double-layer suction cup feet 32 are further divided into suction cups and buffer cavities. The buffer cavities are located inside the suction cups. Both the buffer cavities and the suction cups are made of silicone rubber or fluororubber materials.

[0045] Among them, when the approximately triangular shaking seat 21 is used and the approximately triangular shaking seat buckle 23 cooperates with the card slot of the approximately triangular main fuselage shell, since the points on the approximately triangular buckle rotate around its central axis, the points on the circular motion trajectory will be restricted by the card slot of the approximately triangular main fuselage shell and receive a certain centripetal pulling force, greatly increasing the friction force between the shaking seat 21 and the main fuselage shell. Therefore, relative rotation will not occur, thereby improving the mixing effect; when the approximately triangular shaking seat 21 with a shaking seat buffer groove 22 is used, when the shaking seat buffer groove 22 is subjected to a periodic horizontal centripetal pulling force, the vertical walls on both sides of the shaking seat buffer groove 22 swing and deform relative to the bottom wall, offsetting most of the lateral moving force, thereby avoiding obvious shaking of the main shell and the overall fuselage or even the phenomenon of the "running" of the overall fuselage.

[0046] Among them, the double-layer suction cup feet 32 are divided into suction cups and buffer cavities. The top of the suction cup is placed on the bottom wall of the cavity of the base, and the weight of the mixer body acts on the top of the suction cup. The top of the suction cup transmits the force to the buffer cavity and the suction cup feet. Therefore, the weight of the mixer body discharges the air inside the buffer cavity and the suction cup cavity, generating an air pressure difference, thereby causing the suction cup to generate suction force. When the mixer body vibrates up and down, the up and down telescopic deformation of the buffer cavity and the suction cup can absorb the vibration; when the mixer body has a tendency to move horizontally, the suction force of the suction cup can offset a part of the horizontal moving force. If the horizontal moving force continues to increase, the suction cup and the buffer cavity will generate folding deformation under the action of friction force. Since the mixer body performs circular oscillation, the centrifugal force has switched directions before the buffer cavity and the suction cup reach the limit deformation amount, thus avoiding the running of the whole machine.

[0047] In this embodiment, when the device is in use, after the power is turned on, the indicator light 43 on the circuit PCB board 41 shows red. When the sample liquid test tube is pressed down on the shaking base 21 to shake it, the shaking base 21 makes the motor output shaft 53 move downward through the support protection cap 57, the bearing and the eccentric wheel 55, and drives the wear-resistant gasket 54 below it to press down, prompting the micro switch 42 on the circuit PCB board 41 to close, so that the brushless motor 52 forms a closed circuit under a certain electromotive force, and the motor output shaft 53 starts to operate. The operating action makes the eccentric wheel 55 connected to the motor output shaft 53 perform eccentric motion, and then is transmitted to the shaking base 21 through the deep groove ball bearing 56 and the support protection cap 57, so that the shaking base buffer groove 22 also starts to perform eccentric oscillating motion, thereby driving the sample liquid test tube to move and generate a vortex. Among them, the specific operation steps are as follows;

[0048] First step, when in use, first place the instrument on a stable, clean, non-slip, dry and fireproof tabletop, insert the plug of the adapted power adapter into the instrument's DC power socket 11, and then insert the power adapter plug into the power supply socket.

[0049] Second step, check whether the indicator light 43 of the instrument shows red, and then gently press the sample liquid test tube to be mixed vertically on the pressing area in the center of the soft shaking base 21. The oscillating motion will start, and at the same time the indicator light will change from red to green, indicating that the instrument is running and the sample liquid will quickly generate a vortex; once the user lifts the test tube, the instrument will stop the oscillating motion.

[0050] The above content further elaborates on the present invention in combination with specific embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope determined by the claims submitted for the present invention.
