[0033] Specifically, a plurality of rotation rods no. 410 are annularly and equally angularly rotated on the outside of the middle part of the cleaning pipe 300, the rotation rod no. 410 moves in the direction away from the cleaning pipe 300 under the extrusion elastic force of the arc spring 431, so that different sample bottles of different thicknesses sleeved to the outside of the cleaning pipe 300 can be abutted and fixed by the rotation rod no. 410, the cleaning pipe 300 is convenient for washing and cleaning the sample bottles of different sizes, the jacking mechanism 500 is rotationally arranged on the top of the cleaning pipe 300, the two rotation rod no. 2 510 on the jacking mechanism 500 are rotationally connected through the spring telescopic link 520, the sample bottle can be pressed down by the down mechanism 600 during the cleaning of the sample bottle, the bottle bottom of the sample bottle extrudes the rubber wheel no. 2 511, the rotation rod no. 2 510 rotationally arranged moves in the direction away from each other, the rubber wheel no. 2 511 moves in the position of the bottle bottom, the cleaning pipe 300 is convenient for cleaning the bottle bottom in all directions, and the cleaning effect of the sample bottle is improved.

[0034] As Figures 1-3 Shown, in the embodiment, the outside of water tank 100 is fixed with water outlet pipe 120, and one end of longitudinal pipe 220 is fixed with water inlet pipe 221.

[0035] In the embodiment, during the cleaning process, the valve installed in series on the water inlet pipe 221 is opened, the water pump outside is water transported to the water inlet pipe 221 through the pipeline, then is transported to the longitudinal pipe 220 from the water inlet pipe 221, then is shunted to two cross pipes 210 from the longitudinal pipe 220, and finally is transported to a plurality of cleaning pipes 300 from the cross pipe 210 to clean the sample bottle, and the cleaned water flows to the outside from the water outlet pipe 120.

[0036] As Figure 3As shown, in this embodiment, multiple circular holes 211 are opened at both ends of the horizontal tube 210, and the circular holes 211 are connected and fixed with the cleaning tubes 300 at corresponding positions, thereby enabling the water inside the horizontal tube 210 to be transported to the inside of the cleaning tube 300.

The outside of the cleaning tube 300 is also provided with multiple water outlet holes at different heights and in a circular shape, so that the inner wall of the sample bottle can be flushed in all directions at the same time. The connecting seat 310 enables the rotating rod 410 to rotate on the cleaning tube 300, so that the rotating rod 410 can be adapted to abut and fix sample bottles with different inner diameters.

[0042] In this embodiment, during the downward movement of the sample bottle, the bottom of the sample bottle squeezes the two rubber wheels 511, and the rotating rod 510 in the relative position rotates in directions away from each other, causing the spring telescopic rod 520 to extend. Then, when the sample bottle is not pressed down, the spring telescopic rod 520 automatically contracts under the action of the restoring elastic force of the squeezing spring, causing the rotating rod 510 to bring the rubber wheel 511 back to the initial position. As a result, by reciprocatingly pressing the sample bottle, the rubber wheel 511 used to support the fixed sample bottle can be moved, thereby allowing the water in the cleaning tube 300 to be flushed to the bottom of the bottle in all directions. The spring telescopic rod 520 is a component of the existing technology, and the specific working principle of telescopic rebound is not elaborated here.

[0043] Example 2, based on Example 1, is to enable the sample bottle to be moved downward and changed to another position for cleaning during the cleaning process.

The connecting shaft 630 passes through the sealing cover 110 and is fixed with a circular block 631 at the top end, and a return spring 632 is fixed between the circular block 631 and the sealing cover 110.

[0045] The cam 631 is pressed against the bottom of the bottle 100 to release the pressure spring 632, and the cam 632 is pressed against the bottom of the bottle 100 to release the pressure spring 632.

[0046] like Figure 2 and Figure 5 As shown, in this embodiment, a plurality of limiting columns 130 are evenly fixed on the inner bottom surface of the water tank 100, and the limiting columns 130 are slidably plugged into the corresponding position sleeves 620, and the top ends of the limiting columns 130 are slidably plugged into the sleeves 620, so that the sleeves 620 moving up and down are more stable and smooth.
