Description

pipette cleaning device

Technical Field

The utility model relates to a abluent technical field of pipette, especially kinds of pipette belt cleaning device.

Background

The pipette is slender glass tubes with bulges in the middle, the lower end of the glass tube is in a sharp-mouth shape, marked lines are engraved at the neck of the upper end tube and are used as marks for accurately moving the volume, the inner surface of the pipette needs to be cleaned by cleaning liquid after the pipette is used, the upper end of the pipette is hung in the existing cleaning process, then the cleaning liquid is introduced into the pipette from bottom to top, the cleaning liquid washes the inner surface of the pipette, sewage flows out from the upper end opening of the pipette, and finally the pipette is cleaned.

However, the pipette is placed obliquely, the cleaning liquid cleans the inner wall of the pipette from bottom to top along the length direction of the pipette, and due to the large size of the expanded part in the middle of the pipette, the cleaning liquid cannot clean the upper half space of the expanded part in the middle at all, so that the defect of incomplete cleaning exists.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome prior art's shortcoming, provide kinds of compact structure, wash thoroughly, quick frock pipette, easy operation's pipette belt cleaning device.

kinds of pipette belt cleaning device, it is including wasing dish, sleeve, inlet tube and nut, wash the intraductal cavity that has seted up of dish, the inlet tube welds in the top of wasing the dish, and the passageway and the cavity intercommunication of inlet tube, wash on the top surface of dish and seted up a plurality of through-holes around the circumferencial direction of inlet tube, the welding has the nut that is located directly over the through-hole on the top surface of wasing the dish, the screw hole and the through-hole intercommunication of nut, be provided with the external screw thread on the telescopic cylinder, the sleeve is fixed in on the nut through the screw hole threaded connection of external screw thread and nut, and the bell mouth matched with bell mouth bottom the pipette is seted up at the top of sleeve passageway.

The inlet tube is perpendicular to the cleaning disc.

The water inlet pipe is fixedly arranged in the middle of the cleaning disc.

The nuts are uniformly distributed on the cleaning disc by taking the water inlet pipe as a circle center.

The sleeve and the nut are coaxially arranged.

The utility model has the advantages of it is following: the utility model discloses compact structure, wash thoroughly, quick frock pipette, easy operation.

Detailed Description

The invention will now be described in with reference to the accompanying drawings, but the scope of the invention is not limited to the following:

as shown in fig. 1-2, kinds of pipette belt cleaning device, it is including wasing dish 1, sleeve 2, inlet tube 3 and nut 4, wash and to have seted up cavity 5 in the dish 1, inlet tube 3 welds in the top of wasing dish 1, and inlet tube 3 perpendicular to washs a 1 setting, and inlet tube 3's passageway and cavity 5 intercommunication, wash on the top surface of dish 1 and seted up a plurality of through-holes 6 around the circumferencial direction of inlet tube 3, wash the welding on the top surface of dish 1 and have been located the nut 4 directly over the through-hole 6, the screw hole and the through-hole 6 intercommunication of nut 4, be provided with the external screw thread on the cylinder of sleeve 2, sleeve 2 is fixed in on nut 4 through the screw hole threaded connection of external screw thread and nut 4, sleeve 2 and the coaxial setting of nut 4, the top of sleeve 2 passageway is seted up with pipette bottom.

As shown in fig. 1-2, the water inlet pipe 3 is fixedly arranged in the middle of the cleaning disc 1. The nuts 4 are uniformly distributed on the cleaning disc 1 by taking the water inlet pipe 3 as a circle center.

The working process of the utility model is as follows:

s1, assembling the pipette, namely directly inserting the conical part at the bottom of the pipette 8 into the conical hole 7 of the sleeve 2, and vertically erecting the pipette 8 on the top of the sleeve 2 under the self-gravity of the pipette 8, so that the pipette is quickly assembled, the assembly efficiency is greatly improved compared with the traditional working mode, and the cleaning efficiency of the pipette is further improved ;

s2, the workman passes through the pump and pumps the washing liquid that has pressure in the apical pore of inlet tube 3, the washing liquid is through inlet tube 3 in order, cavity 5, through-hole 6, the screw hole of nut 4, the passageway of sleeve 2, during bell mouth 7 enters into pipette 8 at last, the liquid level of washing liquid in pipette 8 risees gradually under the pump pressure, in the liquid level risees the in-process, the washing liquid must rinse the inflation part 9 of pipette, the washing liquid is spout from the top of pipette 8 at last, therefore this belt cleaning device compares traditional belt cleaning device, can wash times with pipette inner wall is whole, have and wash more thorough characteristics.

The foregoing is merely a preferred embodiment of the invention and is not intended to limit the invention in any way. The technical solutions of the present invention can be used by anyone skilled in the art to make many possible variations and modifications to the technical solution of the present invention, or to modify equivalent embodiments with equivalent variations, without departing from the scope of the technical solution of the present invention. Therefore, any modification, equivalent change and modification of the above embodiments according to the present invention are all within the protection scope of the present invention.
