Description
Technical field
The utility model relates to a kind of cleaning device, a kind of specifically cleaning device that is used for bead particulates.
Background technology
At present, the cleaning needle on the market adopts same needle tubing to realize the filling cleaning fluid and the waste liquid of finding time.Though this relatively simple for structure, it is thorough cleaning to occur in the use usually, susceptible to plugging situation when finding time; And the degree of depth in the wayward cleaning needle insertion reagent cup, make the reagent cup bottom cause cleaning residual easily.
Summary of the invention
The utility model is in order to overcome the deficiency of prior art, and providing a kind of can thoroughly clean, the anticlogging cleaning device of finding time.
To achieve these goals; The utility model has designed a kind of cleaning device that is used for bead particulates; Comprise cleaning needle, it is characterized in that: also comprise the cleaning needle holder, and the adapter that inserts cleaning needle holder top; With the cleaning needle pipe box that inserts the adapter top, a side of adapter is provided with suction tube; The sheathed outer nut that has interior double-screw bolt of the cylindrical of described cleaning needle holder bottom extended spot, and the spring that is used to regulate the cleaning needle extension elongation, spring is positioned at the below of outer nut; Described cleaning needle runs through cleaning needle holder, adapter and cleaning needle pipe box successively; The outer also sheathed suction tube overcoat of cleaning needle also runs through the cleaning needle holder and inserts in the adapter and be connected with suction tube, and described suction tube overcoat is also sheathed outward to be had the cleaning head adjustable pipe of cleaning head and insert in the cleaning needle holder.
Also be provided with the cleaning needle sealing gasket on the sealing surface of described cleaning needle pipe box and adapter.
Also be provided with the suction tube sealing gasket on the sealing surface of described adapter and cleaning needle holder.
Offer cross recess on the periphery of described cleaning head.
Described cleaning needle holder is T-shaped.
The utility model is compared with prior art, has to clean thoroughly anticlogging advantage when finding time.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the cutaway view of the utility model.
Referring to Fig. 1 and Fig. 2,1 is cleaning needle; 2 is the cleaning needle pipe box; 3 is the cleaning needle sealing gasket; 4 is adapter; 5 is suction tube; 6 is the suction tube sealing gasket; 7 is the suction tube overcoat; 8 is the cleaning needle holder; 9 is outer nut; 10 is interior double-screw bolt; 11 is spring; 12 is the cleaning head adjustable pipe; 13 is cleaning head; 14 is cross recess.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As depicted in figs. 1 and 2, the utility model comprises the cleaning needle holder 8 that constitutes mounting base, and holder is T-shaped, and inserts the adapter 4 at cleaning needle holder 8 tops and insert the cleaning needle pipe box 2 of adapter 4 tops.One side of adapter 2 is provided with suction tube 5.The outer nut 9 of double-screw bolt 10 in sheathed having on the cylindrical of cleaning needle holder 8 bottom extended spots, and the spring 11 that is used to regulate cleaning needle 1 extension elongation, spring 11 is positioned at the below of hold-down nut.Cleaning needle 1 runs through cleaning needle holder 8, adapter 4 and cleaning needle pipe box 2 successively.The outer also sheathed suction tube overcoat 7 of cleaning needle 1 also runs through cleaning needle holder 8 and inserts in the adapters 4 and be connected with suction tube 5, and said suction tube overcoat 7 is also sheathed outward to be had the cleaning head adjustable pipe 12 of cleaning head 13 and insert in the cleaning needle holder 8.
Adopt adhering and sealing between adapter 4 and the suction tube 5; Compress sealing through suction tube sealing gasket 6 between adapter 4 and the cleaning needle holder 8; Overlap tightening seal between suction tube overcoat 7 and the cleaning head 13; Compress sealing through cleaning needle sealing gasket 3 between adapter 4 and the cleaning needle pipe box 2.Finally constitute from cleaning head 13 to suction tube 5 closed conduit.
Concrete workflow is following:
Bottom the reagent cup that the needle cleaning device insertion is needed to clean.The self-regulating function of spring 11 makes cleaning needle 1 front end be adjacent to the reagent cup bottom, and the rear end of cleaning needle 1 connects the cleaning fluid filler pipe; Cleaning fluid has certain pressure when injecting; Through the effect of spring 11, cleaning fluid is injected in the reagent cup from the reagent cup bottom, guarantee that flushing is thoroughly.Extract waste liquid by the external suction pump out through suction tube 5 then, cleaning head 13 peripheries have cross recess 14, can guarantee that the bead particulates of certain size can not detach reagent cup along suction channel together.Can reach better cleaning effect after washing, aspirate repeatedly repeatedly.
