For the firm and stress balance that whole platform 5 can be more, bracing piece 3 and montant 4 can the circumference equipartition a plurality ofly, the corresponding circumference equipartition of transmission shaft 10 is a plurality ofly also simultaneously.

In order to adjust the inclination angle of the connecting rod 8 at will, the connecting end connected with the rotating shaft 6 or the sleeve 7 is hinged, and the hinge point is fastened by using a bolt and a nut, so that the angle of the connecting rod 8 is fixed.

In order to avoid that the first compression screw 19 marks the surface of the instrument and may be slip-resistant, the end of said first compression screw 19 is fitted with a rubber pad.

When the invention is used, firstly the retainer ring 20 fixed on the platform 5 is removed, a proper amount of water and cleaning agent are added into the whole body, and the mixed liquid level is preferably at the half height of the filter cylinder 14; at this time, under the action of the compression spring 17 between the vertical rod 4 and the support rod 3, the whole platform 5 is at the uppermost part formed by the platform, namely, the state shown in fig. 2, and at this time, the rotating shaft 6 and the connecting rod 8 on the sleeve 7 are both positioned above the barrel body 1, so that the instruments can be conveniently placed and fixed.

When the instrument is fixed, the first compression screw 19 on the fixing buckle 9 needs to be rotated, and one side or one corner of the instrument can be fixed on the connecting rod 8 by the first compression screw 19 and the fixing block 18; the rubber pad is arranged at the end part of the first compression screw 19, so that the effects of skid resistance and indentation resistance are achieved; because the number of the fixing buckles 9 is large, the instruments to be cleaned can be fixed one by one, the fixing stability is ensured, and the instruments cannot be easily thrown away.

After the apparatus is fixed, the retainer ring 20 needs to be fixed at the moment, so that splashing pollution in the subsequent cleaning process is prevented; after the retainer ring 20 is fixed, a second compression screw 21 is screwed to enable the wire wheel 11 and the transmission shaft 10 to be in the same rotation state, then the motor can be started, and the motor is firstly adjusted to be in a forward and reverse reciprocating rotation mode; in the forward and reverse reciprocating rotation mode, the rotating shaft 6, the sleeve 7 and the transmission shaft 10 are in forward and reverse reciprocating rotation; while the rotation of the shaft 6 and the sleeve 7 is reversed.

When the transmission shaft 10 drives the wire wheel 11 to rotate the rotating shaft 6 in a forward and reverse reciprocating manner, the wire wheel 11 winds the rope 12 when rotating in the forward direction, so that the rope 12 is tightened, the whole platform 5 is pulled downwards, and the motor, the rotating shaft 6, the sleeve 7, the baffle 13 and the like arranged on the platform 5 all descend together; and is arranged in the cleaning agent in the barrel body 1; when the platform falls to a certain degree, the wire wheel 11 rotates reversely, and the vertical rod 4 rises under the action of the pressure spring 17 and drives the whole platform 5 to rise; therefore, the up-and-down reciprocating movement of the platform 5 is realized, and at the moment, the rotating shaft 6, the sleeve 7, the connecting rod 8, the baffle 13 and the like attached to the platform 5 all move up-and-down in a reciprocating manner.

When the instrument is completely immersed in the cleaning agent after descending along with the whole platform 5 (the instrument is positioned in the filter cylinder 14), and along with the rotation of the rotating shaft 6 and the sleeve 7, the instrument fixed on the connecting rod 8 rotates along with the rotating shaft, so that the instrument rotates in the cleaning agent to generate strong cleaning force, and therefore, solid impurities such as stains, human tissues and the like adhered to the instrument are washed away; meanwhile, the rotating shaft 6 and the connecting rod 8 on the sleeve 7 are in a corresponding up-down state, and the rotating shaft 6 and the sleeve 7 are in opposite rotation directions, so that the instrument fixed on the rotating shaft 6 and the instrument fixed on the sleeve 7 are in opposite rotation; therefore, the inertial flow of the cleaning agent can be effectively avoided, the cleaning agent is fully disturbed, and the cleaning effect is better.

After the apparatus is completely separated from the cleaning agent along with the ascending of the whole platform 5 (the state shown in fig. 2), at the moment, along with the rotation of the rotating shaft 6 and the sleeve 7, the cleaning agent adhered to the apparatus can be dried to a certain degree under the action of centrifugal force, meanwhile, the adhered impurities can be thrown away together, meanwhile, the baffle 13 is not positioned inside the filter cartridge 14, and under the damping action of the rotating shaft 6 and the baffle 13, the baffle 13 can also rotate along with the rotating shaft 6, so that the solid impurities on the upper end face of the baffle 13 are thrown away.

Meanwhile, in the process that the whole platform 5 reciprocates up and down, the instrument is firstly gradually immersed in the cleaning agent and then gradually separated from the cleaning agent, so that a certain cleaning effect can be achieved.

On the other hand, as the platform 5 descends, the baffle 13 at the lower end of the rotating shaft 6 is also driven to be placed inside the filter cartridge 14 and move downwards along the filter cartridge 14 (the filter cartridge 14 is fixed, and the outer edge surface of the baffle 13 is provided with the rubber baffle 15, so that a certain resistance exists between the baffle 13 and the filter cartridge 14, at this time, the rotating shaft 6 cannot drive the baffle 13 to rotate together, that is, the baffle 13 does not rotate when inside the filter cartridge 14), and because the cleaning agent is placed inside the barrel 1, when the baffle 13 moves from top to bottom, the baffle 13 can press the cleaning agent below the baffle 13, so that the cleaning agent flows upwards from the gap 23 between the filter cartridge 14 and the barrel 1, then flows to the upper side of the filter cartridge 14 after being filtered by the filter cartridge 14, and the solid impurities can be located below the baffle 13 by the pressing of the baffle 13, thereby ensuring that the content of the solid impurities in, namely, when the instrument is cleaned, the solid sundries can be prevented from being wound on the instrument again.

When the baffle 13 is at the lowest part of the stroke, the baffle 13 and the filter cartridge 14 form a 'clean area' with an upward opening, and the instruments on the rotating shaft 6, namely the sleeve 7 are placed in the 'clean area' for cleaning, and solid impurities are remained in the 'clean area' after a period of cleaning; at the moment, the baffle 13 can rise along with the platform 5, when the baffle 13 is still placed in the cleaning agent, the baffle 13 can push the water above the baffle 13 upwards, and the water above the baffle 13 flows to the space 23 from the periphery of the baffle 13 through the filter cartridge 14 and then flows to the lower part of the baffle 13; however, when the solid impurities pass through the filter cartridge 14, the solid impurities are blocked and remain on the upper end surface of the baffle 13, and when the baffle 13 continues to rise, the baffle 13 can be separated from the cleaning agent, and at the moment, the solid impurities can be adhered to the upper end surface of the baffle 13; when the baffle 13 continues to rise, the baffle 13 can be separated from the filter cartridge 14, and the baffle 13 is not subjected to the resistance of the filter cartridge 14; and is driven by the rotating shaft 6 to rotate; so that the solid impurities on the baffle 13 are thrown away and fall on the inner wall of the barrel body 1 and gradually slide into the interval 23.

Therefore, the baffle 13 can reciprocate up and down, so that solid impurities in the cleaning agent can be filtered once when the apparatus descends into the cleaning agent for cleaning at each time, thereby avoiding cross contamination and improving the cleaning effect.

When not needing to wash, can dry the apparatus this moment, during specific dry operation, at first not hard up second housing screw 21 makes transmission shaft 10 not drive line wheel 11 and rotates, later the adjustment motor is one-way rotation mode, because line wheel 11 is not transmitting this moment, then whole platform 5 can remain motionless, only pivot 6 and sleeve 7 rotate to realize that the apparatus is in the top of cleaner always, rotate the drying.

After the primary cleaning is finished, ultrasonic cleaning, subsequent high-temperature disinfection and other steps can be used, so that the use standard is met.

Along with washing many times, after the solid-state debris content in the inside cleaner of staving 1 is too high, perhaps the cleaner is contaminated, when unable wasing, can open drain valve 2 this moment to change 1 inside water of staving and cleaner, thereby carry out subsequent washing.

The device can completely immerse the instrument in the cleaning agent, so that the problem of incomplete cleaning caused by traditional water flow flushing is avoided, the complex instrument can be better cleaned, and the mechanical cleaning of the complex instrument is realized.

The diameter of the line wheel 11 in the device is smaller, and meanwhile, the rotation speed of the motor during forward and reverse reciprocating rotation is also smaller, so that the vertical reciprocating movement speed of the whole platform 5 is slower, a better filtering effect can be realized, and the time for cleaning instruments in the cleaning agent is prolonged.

The cleaning agent is stored in the barrel body 1, so that the use of the cleaning agent is saved, the burden of wastewater treatment is reduced, the traditional operations such as simple brushing and the like are changed, and a motor is used for driving a plurality of instruments to fully disturb in the cleaning agent, so that thorough cleaning is realized; the cleaning efficiency is high, and no manual work is needed; and because each instrument is fixed respectively, the mutual collision between the instruments can be avoided, and the instruments are prevented from being scratched.

The rotation directions of the fixed instruments on the rotating shaft 6 and the sleeve 7 in the device are opposite, so that the cleaning agent can be kept in a disturbance direction, the instruments can be sufficiently washed by the cleaning agent, and the problem of insufficient cleaning force when the cleaning agent rotates in the same direction is solved.

The baffle 13 is ingeniously arranged at the lower end of the rotating shaft 6, and the baffle 13 is matched with the filter cartridge 14, so that solid impurities above the baffle 13 inside the filter cartridge 14 can be greatly reduced when the device is cleaned, and the problems of incomplete cleaning and repeated pollution are avoided.

This device can be through simple operation, has realized the drying to the apparatus, the later stage operation such as disinfection of being convenient for, simultaneously because the apparatus is undulant great to the stirring of cleaner in this device, consequently abluent speed is comparatively fast, the effectual abluent time that has shortened has improved efficiency.
