Detailed Description
The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.
Example 1
As shown in fig. 1-3, a formula pipette belt cleaning device is inhaled to magnetism, including framework 1, contain the washing liquid in framework 1, top surface and interior bottom surface are all fixed to be inlayed and are equipped with otter board 2 in framework 1, and it needs to notice that draw-in groove 9 has all been seted up on two just right lateral walls of otter board 2, and the pipette joint is between two draw-in grooves 9.
The outer cover of 3 dead levers of dead lever is equipped with a coaxial setting's an external screw thread section of thick bamboo 6, and the upper and lower end of an external screw thread section of thick bamboo 6 all with otter board 2 fixed connection, need to explain that, a plurality of intercommunicating pores 10 of evenly having arranged on the lateral wall of an external screw thread section of thick bamboo 6, the washing liquid in the framework 1 passes through otter board 2 and intercommunicating pore 10 and pipette inside and external contact, can sparsely carry out the more dirty water of pipette periphery, improves clean effect to a certain extent.
An external screw thread section of thick bamboo 6 overcoat is equipped with internal thread ring 7, internal thread ring 7 is through the screw thread on the inside wall and an external screw thread section of thick bamboo 6 threaded connection, internal thread ring 7 goes up the fixed permanent magnetism piece 8 that is equipped with and attracts mutually with 4 heteropolars of magnetic sliding ring that inlays, because threaded connection between internal thread ring 7 and the external screw thread section of thick bamboo 6, therefore internal thread ring 7 can be the heliciform downstream, can drive the inside 4 heliciform descendants of magnetic sliding ring that attract mutually rather than the heteropolars of an external screw thread section of thick bamboo 6, clean.
The invention can be illustrated by the following operating modes:
when the invention is used, the internal thread ring 7 is initially positioned at the upper end of the external thread cylinder 6 and moves downwards along the external thread cylinder 6 under the action of self gravity, and the internal thread ring 7 moves downwards in a spiral shape due to the threaded connection between the internal thread ring 7 and the external thread cylinder 6.
At internal thread ring 7 can be the in-process that the heliciform removed downwards, the magnetism sliding ring 4 on the dead lever 3 can be the heliciform decline under the drive of permanent magnetism 8, and the elastic bag 5 on the magnetism sliding ring 4 can hug closely the pipette inside wall under the effect of centrifugal force and be the heliciform decline, can carry out abundant washing to the pipette inside wall, improves the cleaning performance greatly.
Example 2
As shown in fig. 4, the present embodiment is different from embodiment 1 in that: all rotate on the lateral wall of framework 1 both sides and be connected with the bracing piece 11 of vertical setting, framework 1 lower extreme is equipped with the base 12 that the level set up, and the lower extreme of two bracing pieces 11 all with base 12 fixed connection, be equipped with tilting mechanism between base 12 and the framework 1.
The turnover mechanism comprises a ceramic piezoelectric sheet 13 fixed at the lower end of the internal thread ring 7, the ceramic piezoelectric sheet 13 is extruded and deformed at the moment of impact to generate a polarization phenomenon, electric charge is transferred to generate current, the internal thread ring 7 is an electromagnet coupled with the ceramic piezoelectric sheet 13, a magnetic block 14 is fixedly connected to the side wall of the base 12, and the magnetic block 14 and the electrified internal thread ring 7 repel each other in the same polarity.
In this embodiment, when internal thread ring 7 descends to the bottom surface in framework 1, ceramic piezoelectric plate 13 of its lower extreme can strike framework 1's interior bottom surface and produce the electric current and make internal thread ring 7 produce the magnetism the same with magnetic block 14 magnetism, two magnets of the same magnetic pole are difficult to just right, then whole framework 1 can take place the upset, make internal thread ring 7 rotate the upper end, internal thread ring 7 will move down under self action of gravity, drive magnetic slip ring 4 and remove in the pipette, so relapse, can scrub the pipette inside wall repeatedly, not only the cleaning effect further improves, the simple operation is gone back, time saving and labor saving.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
