In order to facilitate the liquid to push the filter screen 15 to swing, the end of each filter screen 15 is fixed with a water blocking sheet 23, and the water blocking sheet 23 is made of rubber.

In order to make the entire platform 5 more stable and force-balanced, the support rods 3 and vertical rods 4 can be distributed evenly around the circumference, and the transmission shafts 10 can also be distributed evenly around the circumference.

In order to be able to adjust the inclination angle of the connecting rod 8 arbitrarily, the end of the connection with the rotating shaft 6 or the sleeve 7 is hinged, and the hinge point is fastened with bolts and nuts, so that the angle of the connecting rod 8 is fixed. .

In order to prevent the first pressing screw 19 from pressing marks on the surface of the instrument, and to prevent slippage, a rubber pad is installed at the end of the first pressing screw 19 .

When using the present invention, first remove the retaining ring 20 fixed on the platform 5, add an appropriate amount of water and cleaning agent to the interior of the barrel, and the liquid level should be lower than the height of the baffle 13 when its stroke is the highest; Under the action of the compression spring 17 between the vertical rod 4 and the support rod 3, the entire platform 5 is at the top of its formation, that is, the state shown in Figure 2. At this time, the rotating shaft 6 and the connecting rod 8 on the sleeve 7 are both It is located above the barrel body 1, which facilitates the placement of the instrument and the fixing of the box.

When fixing the instrument, it is necessary to rotate the first pressing screw 19 on the fixing buckle 9, so that one side or corner of the instrument can be fixed on the connecting rod 8 by the first pressing screw 19 and the fixing block 18; A rubber pad is installed at the end of the pressing screw 19, so as to play the role of anti-slip and anti-indentation; because the number of fixing buckles 9 is relatively large, the instruments to be cleaned can be fixed one by one, and the stability of the fixing can be ensured Sex, will not be easily thrown away.

After the instrument is fixed, the retaining ring 20 needs to be fixed at this time, and placed in the subsequent cleaning process, splashing pollution; after the retaining ring 20 is fixed, screw the second compression screw 21, so that the wire wheel 11 and the transmission The shaft 10 is in the same rotation state, and then the motor can be started. First, the motor is adjusted to the mode of forward and reverse reciprocating rotation; in the forward and reverse reciprocating rotation mode, the rotating shaft 6, the sleeve 7 and the transmission shaft 10 are all in the forward and reverse reciprocating rotation; At the same time, the rotation of the rotating shaft 6 and the sleeve 7 is in the opposite state.

When the transmission shaft 10 drives the reel 11 to reciprocate the reciprocating shaft 6, when the reel 11 is rotating forward, it will wrap the rope 12 to tighten the rope 12. At this time, the entire platform 5 will be pulled downward, and the platform 5 will be up The installed motor, rotating shaft 6, sleeve 7, baffle 13, etc. will all descend together; they will be placed in the liquid in the barrel 1; when it descends to a certain extent, the wire pulley 11 will be reversed at this time. Under the action of the spring 17, the vertical rod 4 will rise, and drive the entire platform 5 to rise; thereby realizing the reciprocating movement of the platform 5 up and down.

When the instrument is completely immersed in the liquid after descending with the entire platform 5, with the rotation of the rotating shaft 6 and the sleeve 7, the instrument fixed on the connecting rod 8 will rotate accordingly, so that the instrument rotates in the liquid , it will generate a strong cleaning force, so as to wash away impurities such as stains, human tissue and other impurities attached to the instrument; at the same time, the connecting rod 8 on the rotating shaft 6 and the sleeve 7 is in a state corresponding to the top and bottom, and the rotating shaft 6 and the sleeve 7 are in a corresponding state. The direction of rotation is opposite, so the instruments fixed on the rotating shaft 6 and the instruments fixed on the sleeve 7 will produce opposite rotations; thus, the inertial flow of the liquid can be effectively avoided, and the liquid can be fully disturbed, so that the cleaning effect is better; The instruments are completely immersed in the cleaning agent, which avoids the problem of incomplete cleaning caused by traditional water flushing, and can better clean complex instruments and realize mechanical cleaning of complex instruments.

When the instrument is completely separated from the liquid along with the entire platform 5, the liquid attached to the instrument can be dried to a certain extent under the action of centrifugal force with the rotation of the rotating shaft 6 and the sleeve 7 at this time. Also don't throw it away.

At the same time, in the process of the whole platform 5 reciprocating up and down, the instrument will be gradually immersed in the liquid at first, and then gradually separated from the liquid, so that it can play a certain role in cleaning.

In addition, as the platform 5 moves up and down, the baffle 13 at the lower end of the rotating shaft 6 will also be driven to reciprocate up and down, and because the interior of the barrel 1 is placed with liquid, and the height of the liquid is lower than the uppermost end of the baffle 13 stroke Therefore, when the baffle 13, due to the buoyancy of the liquid, the liquid will push the filter screen 15 under each through hole 14 at this time, so that the filter screen 15 is in a horizontal state, that is, the filter screen 15 is in a state of closing the through hole 14. At this time, the water inside the barrel 1 will be filtered through the filter screen 15, and the impurities will be squeezed to the bottom of the barrel 1 as the baffle 13 descends; thus ensuring that the liquid above the filter screen 15 contains less impurities , that is, when the instrument is cleaned, impurities can be prevented from being entangled on the instrument again. Then, when the filter screen 15 rises, under the action of water, the filter screen 15 will swing downward, so that the through hole 14 is not blocked by the filter screen 15. At this time, the liquid containing impurities above the baffle 13 will pass through the through hole. 14 flows below baffle 13; until baffle 13 is completely above the liquid. Through this reciprocation, the impurities in the liquid can be filtered every time the instrument is lowered into the liquid for cleaning, thereby avoiding cross-contamination and improving the cleaning effect.

When cleaning is not required, the instrument can be dried at this time. The specific drying operation is to first loosen the second compression screw 21 so that the transmission shaft 10 does not drive the wire pulley 11 to rotate, and then adjust the motor to a one-way rotation mode, At this time, since the wire wheel 11 is not driving, the entire platform 5 will remain stationary, and only the rotating shaft 6 and the sleeve 7 will rotate, so that the instrument is always above the liquid for rotating and drying.

After the preliminary cleaning is completed, ultrasonic cleaning and subsequent high-temperature disinfection can be used to meet the standard of use.

With multiple cleanings, when the impurity content in the liquid inside the barrel 1 is too high, or the liquid is polluted and cannot be cleaned, the drain valve 2 can be opened at this time, and the water and cleaning inside the barrel 1 can be replaced. agent for subsequent cleaning.

By completely immersing the instruments in the cleaning agent, the device avoids the problem of incomplete cleaning caused by traditional water flushing, can better clean complex instruments, and realize mechanical cleaning of complex instruments.

The device uses the barrel 1 to store the cleaning agent, which saves the use of the cleaning agent, reduces the burden of waste water treatment in the later stage, and changes the traditional operation such as simple brushing. Sufficient disturbance, so as to achieve thorough cleaning; high cleaning efficiency, no need for manual labor; and because each instrument is fixed separately, it can avoid the collision between the instruments and avoid the scratches of the instruments.

In this device, the rotation directions of the rotating shaft 6 and the instruments fixed on the sleeve 7 are opposite, so the cleaning agent can be moved in a direction of constant disturbance, so that the cleaning agent can fully wash the instruments and avoid the cleaning agent in the same direction When rotating, the cleaning force is insufficient.

The device cleverly installs a baffle 13 at the lower end of the rotating shaft 6, and sets a through hole 14 and a filter screen 15 on the baffle 13, so that the sundries above the baffle 13 will be automatically removed as the entire platform 5 moves up and down. Collected to the bottom of the baffle 13, so that the instrument will not be entangled by the sundries in the cleaning agent during cleaning, resulting in the problem of incomplete cleaning and repeated pollution.

The device can realize drying of the equipment through simple operation. At the same time, because the agitation and fluctuation of the cleaning agent by the equipment in the device is relatively large, the cleaning speed is relatively fast, which effectively shortens the cleaning time and improves the efficiency.
