Therefore, the endoscope 17 can not be contacted with the outside in the cleaning and disinfection process or the storage time period after the cleaning and disinfection process from the beginning of the cleaning and disinfection to the next use, so that the secondary pollution is completely avoided, and the endoscope is compared with the largest difference of the existing cleaning and disinfection modes

Meanwhile, the present application also provides a preferable method for sealing the storage box body 181 and the storage box cover 182, as shown in fig. 8 to 10, two sides of the storage box body 181 are provided with fasteners 183; the fastening piece 183 is a common spring fastener, fastening plates are arranged at corresponding positions on two sides of the storage box cover 182, hooks of the fastening piece 183 can be hung on the fastening plates of the storage box cover 182, the storage box cover 182 is integrally pressed down, the bottom surface of the storage box cover 182 is tightly attached to the top surface of the storage box body 181, and the fastening sealing between the bottom surface of the storage box cover 182 and the top surface of the storage box body 181 is realized.

In some embodiments, the present application provides a preferred configuration for a sealed docking, as set forth below. As shown in fig. 12, the valve core assembly O includes a valve core O1, a return spring O2, and a seal ring O3. The top of the valve core O1 is provided with a ring groove, the bottom is provided with a step ring, the bottom is provided with a first vent hole O1A which is arranged along the axial direction and is of a blind hole structure, and a plurality of second vent holes O1B which are arranged along the radial direction and penetrate through the peripheral wall of the first vent hole O1A are annularly arrayed on the peripheral surface. The sealing ring O3 is sleeved and fixed on the ring groove of the valve core O1. The return spring O2 is sleeved on the outer periphery of the valve spool O1 and is limited between the sealing ring O3 and the land ring of the valve spool O1.

As shown in fig. 7, the second cartridge interface a2 is of a tube-like construction and is raised above the bottom of the cartridge assembly 18 and has a stop ring P disposed therein. The second pipe interface B2 is also of a pipe-like construction. The movable connection of the valve core assembly O is specifically as follows: the valve core O1 is arranged through the inner periphery of the stop ring P and the top of the valve core O1 faces the storage box component 18; the stop ring P is clamped between the return spring O2 and the sealing ring O3; the return spring O2 is always in a compressed state and has both end surfaces in contact with the step surface of the spool O1 and the end surface of the stopper ring P. As shown in fig. 5 and 7, the sealing interface between the second tube interface B2 and the second cartridge interface a2 is specifically: the second pipe interface B2 is inserted from the bottom of the second box interface A2, so that the top of the second pipe interface B2 is opposite to the bottom of the valve core assembly O.

Thus, in the cleaning and sterilizing process, the second tube interface B2 and the second cartridge interface a2 are brought close to each other by the sealing engagement, and the second tube interface B2 exerts a biasing force on the valve element O1 toward the storage cartridge assembly 18, thereby switching the valve element assembly O to the open state. The switching of the valve core assembly O to the open state specifically comprises the following steps: the valve spool O1 moves toward the internal cavity of the storage case body 181, and thus the sealing ring O3 is separated from the stopper ring P, and a portion of the first vent hole O1A and the second vent hole O1B enters the internal cavity of the storage case body 181. In this state, when the liquid inlet device 11 shown in fig. 1 is activated and the liquid inlet control valve 12 is opened, that is, during the process of introducing the external disinfectant into the inner cavity of the storage box body 181, when the disinfectant reaches the position of the second tube interface B2, the disinfectant firstly enters the first vent hole O1A, then enters the inner cavity of the storage box body 181 through the second vent hole O1B, so as to start the cleaning of the endoscope in the storage box assembly 18, and after the cleaning is finished, the disinfectant flows to the second tube interface B2 through the second vent hole O1B and the first vent hole O1A in sequence, and finally flows out through the discharge control valve 14, so as to complete the cleaning and disinfection of the endoscope 17.

When the cleaning and disinfection are finished and the sealing and butt joint between the second pipe interface B2 and the second box interface a2 is released, the valve core assembly O can be automatically switched to the normally closed state through the return spring O2, as shown in fig. 10 and 11, the normally closed state of the valve core assembly O is specifically: the force generated by the deformation compression of the return spring O2 enables the annular groove surface of the valve core O1 and the contour surface of the stop ring P to form extrusion force on the sealing ring O3, so that the sealing ring O3 generates extrusion deformation and forms the sealing of the gap between the peripheral surface of the valve core O1 and the stop ring P, and the storage box assembly 18 can be isolated from the outside. In conclusion, the switching between the open state and the normally closed state of the valve element assembly O is automatically performed along with the start and the end of the cleaning and disinfecting process, so that the endoscope 17 can be effectively prevented from contacting the outside in the state switching process of the valve element assembly O, that is, the endoscope 17 is ensured to be completely prevented from being secondarily polluted from the start of cleaning and disinfecting to the end of cleaning and disinfecting until the endoscope is used next time.

It should be noted that the sealing interface may be achieved by making the second tube interface B2 and the second cartridge interface a2 as matching threaded interfaces that are screwed together to form a tight force against the valve cartridge O1, which is directed toward the storage cartridge assembly 18, by the second tube interface B2. Meanwhile, in order to enhance the sealing effect of the valve core assembly O in the normally closed state, as shown in FIG. 11, the inner ring edge of the blocking ring P is provided with a sealing surface P1 facing towards the storage box assembly 18; the sharp limit of sealing surface P1 edge is the smooth transition face that chamfer or radius or blunted formed, and preferred sealing surface P1 is the radius face in this application, and what sealing ring O3 actually contacted under normally closed state is just valve core O1's annular face and sealing surface P1 like this to guarantee that sealing ring O3 can be comparatively full contact effect, and then can be abundant by extrusion deformation and produce good sealed effect.

In some embodiments, as shown in fig. 1 and 3, the negative pressure cleaning and disinfecting machine further comprises a first tube interface B1, a third tube interface B3, a vacuum control valve 5 and a vacuum device 6. As shown in fig. 1 and 10, the cartridge assembly 18 is also provided with a first cartridge interface a1 and a third cartridge interface A3, and further includes a flexible tube 181C.

The third pipe interface B3, the vacuum-pumping control valve 5 and the vacuum-pumping device 6 are sequentially connected by pipelines. The hose 181C is positioned in the storage box body 181, and both ends of the hose are respectively connected with the first box interface A1 and the endoscope 17; here, the side leakage port of the endoscope 17 is preferably connected.

As shown in fig. 5 to 7, the first cartridge port a1 and the third cartridge port A3 are both the same as the second cartridge port a2 in structure, and both are provided with a check ring P and a movably connected valve core assembly O inside. The first pipe joint B1 and the third pipe joint B3 are both identical in structure to the second pipe joint B2. In this way, when the spool assembly O is in the normally closed state, the first and third cartridge ports a1 and A3 can be sealed. The first pipe interface B1 and the first box interface a1, and the third pipe interface B3 and the third box interface A3 can be in sealing butt joint as between the second pipe connector B2 and the second box interface a2, and the corresponding valve core assembly O is switched to the open state, and the inside of the storage box assembly 18 is communicated with the pipes connected with the first pipe interface B1 and the third pipe interface B3.

Thus, after the sealed butt joint is formed, when the endoscope 17 is immersed in the disinfectant to be disinfected and cleaned, the vacuum control valve 5 and the vacuum pumping device 6 are opened, so that the inside and the outside of the endoscope 17 can be simultaneously vacuumized, the inside of the endoscope 17 is in a negative pressure state, and the disinfectant can smoothly enter the endoscope 17, thereby carrying out all-around cleaning and disinfection on the inside and the outside of the endoscope 17. The purpose of simultaneously vacuumizing the inside and outside of the endoscope 17 is to equalize the pressure inside and outside the endoscope 17 and prevent the internal elements of the endoscope 17 from being damaged by the air pressure difference formed inside and outside the endoscope 17.

More preferably, as shown in fig. 1 and 3, the negative pressure cleaning and disinfecting machine further comprises a fresh air valve 3 and an air filtering device 4. The first box port A1, the first pipe port B1, the fresh air valve 3 and the air filtering device 4 are sequentially connected by pipelines; the third box port A3, the third pipe port B3, the fresh air valve 3 and the air filter device 4 are sequentially connected by pipelines. After the endoscope 17 is simultaneously evacuated, the fresh air valve 3 is opened, so that the outside air can be simultaneously introduced into the endoscope 17 and the inner cavity of the storage box assembly 18, the atmospheric pressure is recovered to normal pressure, and the subsequent discharge of disinfectant is facilitated. The air filter device 4 is provided here to prevent contamination of the endoscope 17 by pre-treatment of the filter and disinfection as ambient air is passed into the interior of the endoscope 17 and the lumen of the magazine assembly 18.

Further, as shown in fig. 5 and 7, the top surfaces of the first tube joint B1, the second tube joint B2, and the third tube joint B3 are engaged with the fixing packing Q. The first pipe joint B1, the second pipe joint B2 and the third pipe joint B3 form sealing butt joint, and when the jacking force is formed on the corresponding valve core assembly O, the top surface of the sealing gasket Q and the valve core O1 can be tightly attached to each other to form sealing, and further drainage disinfectant or pumped gas cannot leak.

In some embodiments, as shown in fig. 1 and 4, a cleaning station 1 is also included. A cleaning groove is arranged in the cleaning workbench 1, and the first pipe interface B1 and the second pipe interface B2 are both arranged at the bottom of the cleaning groove of the cleaning workbench 1; the pipes connected to the first pipe joint B1 and the second pipe joint B2 are provided outside the cleaning table 1. The first cartridge interface a1 and the second cartridge interface a2 are both disposed at the bottom of the storage cartridge assembly 18. The storage cartridge assembly 18 can be placed bottom down in the wash basin of the wash station 1 with the first tube interface B1 in sealing abutment with the first cartridge interface a1, the second tube interface B2, and the second cartridge interface a 2. Thus, after the sealed docking, the first tube interface B1 and the first box interface a1, and the second tube interface B2 and the second box interface a2 are inserted and approached to each other by the gravity of the storage box assembly 18, so that the first tube interface B1 and the second tube interface B2 form a tightening force against the corresponding valve core assembly O, and the corresponding valve core assembly O is switched to the open state.

Further, comprises a movable arm 2 and a power assembly 15; the moveable arm 2 is located above the carriage assembly 18. The third pipe joint B3 is arranged on the bottom surface of the movable arm 2; the third cartridge interface a3 is disposed on the top surface of the storage cartridge cover 182. The power assembly 15 is capable of driving the movable arm 2 to perform a clamping motion, and by the clamping motion, the movable arm 2 generates a vertical downward force on the magazine assembly 18. The vertical downward pressure makes the third cartridge interface a3 and the third tube interface B3 form a sealed butt joint, so that the third tube interface B3 forms a jacking force on the corresponding valve core assembly O, and the valve core assembly O is switched to an open state. Here, the power assembly 15 can be any component capable of driving the movable arm 2 to move, such as a motor, a hydraulic cylinder, etc., and the clamping movement of the movable arm 2 can also be any component capable of generating a vertical downward pressure movement on the storage box assembly 18, such as a lifting movement relative to the storage box assembly 18, etc., and a preferred structure of the present application is shown in fig. 1, 4 and 5, wherein the power assembly 15 is a cylinder assembly, and the plunger tip of the power assembly 15 forms an articulated joint at the tail end of the movable arm 2; the middle section of the movable arm 2 is hinged to one side of the cleaning workbench 1; the clamping movement is a rotational movement of the movable arm 2 around a hinge point on the wash table 1. When the plunger of the power assembly 15 is extended, the movable arm 2 forms a closed state relative to the table 1 through a rotational movement and generates a vertical downward pressure on the cartridge assembly 18, thereby bringing the third cartridge interface a3 and the third tube interface B3 into a sealed abutment. When the plunger of the power assembly 15 is retracted, the movable arm 2 is opened relative to the work table 1 by the rotational movement and releases the vertical downward pressure on the storage box assembly 18, thereby releasing the sealed docking of the third box interface A3 and the third tube interface B3

The second cartridge interface a2, the second pipe interface B2, the air feed control valve 8, and the air feed device 7 are sequentially connected by piping. Thus, after the disinfection solution is introduced into the endoscope 17 and the inner and outer surfaces of the endoscope 17 are cleaned by pumping negative pressure inside and outside the endoscope 17, the gas can be actively fed from the bottom of the storage box assembly 18 through the second box interface A2 by starting the gas feeding device 7 and opening the gas feeding control valve 8, so that the storage box assembly 18 is repressurized, and the process is repressurized from the bottom of the storage box assembly 18 in an active gas feeding manner, so that bubbles can be continuously generated in the process, and when the bubbles are attached to the endoscope 17 and damaged, the generated shock wave can perform powerful cleaning on the outer surface of the endoscope 17 again and generate the same bubbling cleaning effect on the inner cavity of the storage box assembly 18.

More preferably, a check valve 20 is further provided between the second pipe connector B2 and the air supply control valve 8, so that the check valve 20 can be opened by the air flow during the air supply of the air supply device 7, and the check valve 20 can be actively closed after the air supply is finished, thereby preventing the disinfectant in the inner cavity of the storage box assembly 18 from flowing back to the air supply control valve 8.

Further, a first ventilation control valve 19 and a second ventilation control valve 21 are also included. The first pipe interface B1, the fresh air valve 3 and the vacuumizing control valve 5 are respectively connected with the second ventilation control valve 21 through pipelines, and the second pipe interface B2, the fresh air valve 3 and the vacuumizing control valve 5 are respectively connected with the first ventilation control valve 19 through pipelines, so that in the process of starting the air supply device 7 to supply air to the inner cavity of the storage box assembly 18, the second ventilation control valve 21 and the fresh air valve 3 are opened and the first ventilation control valve 19 is closed, external air can be introduced into the endoscope 17, and the endoscope 17 keeps balance of internal and external pressure in the bubbling cleaning process.

In this way, after the cleaning and disinfection are completed and the disinfectant is removed, the disinfectant remaining on the surface of the endoscope 17 can be vaporized by starting the gas supply device 7 to supply gas into the storage box assembly 18 and starting the heating device 9 to heat the gas flowing through, thereby ensuring the drying of the inner cavity of the storage box assembly 18.

In some embodiments, as shown in fig. 1-4, and 13, the negative pressure washer disinfector further comprises a pressure sensor 13, a flow meter 16, and a control system 1000. The pressure sensor 13 and the flow meter 16 are respectively loaded between the second pipe joint B2 and the liquid inlet control valve 12, between the second pipe joint B2 and the flow meter 16, between the second pipe joint B2 and the gas delivery control valve 8, and between the second pipe joint B2 and the heating control valve 10; the vacuum pumping control valve 5, the vacuum pumping device 6, the air supply device 7, the air supply control valve 8, the heating device 9, the heating control valve 10, the liquid inlet device 11, the liquid inlet control valve 12, the pressure sensor 13, the discharge control valve 14, the power assembly 15, the flow meter 16, the first ventilation control valve 19 and the second ventilation control valve 21 are respectively electrically connected with the control system 1000.

The flow meter 16 is used for monitoring the total flow of the disinfectant, so that it can be indirectly known whether to feed a sufficient amount of disinfectant into the storage box assembly 18 when the endoscope 17 is cleaned and disinfected, whether to completely discharge the cleaning disinfectant in the storage box assembly 18 when the cleaning and disinfection are finished and the disinfectant is discharged, and the control system 1000 is informed through signal transmission after the sufficient amount of disinfectant and the discharged disinfectant are fed, and then the control system 1000 controls the on-off of the corresponding pipeline based on the received signals. And pressure sensor 13 is used for monitoring the storage box subassembly 18 internal pressure condition, and whether the monitoring has been in predetermineeing the negative pressure value when to storage box subassembly 18 inside evacuation, whether the monitoring has been in predetermineeing the positive pressure value when to storage box subassembly 18 inside repressing, and pressure sensor 13 informs control system 1000 through signal transmission after satisfying the pressure requirement, is controlled the break-make of corresponding pipeline by control system 1000 based on the signal that receives again. In conclusion, the design is that the whole negative pressure cleaning and disinfecting machine can be intelligently controlled and is more convenient and faster to use.

It should be noted here that, when the movable arm is closed, the movable arm can cooperate with the cleaning workbench to form an up-down clamp for the storage box assembly, so as to ensure that the valve core assembly in the first box interface, the 1 second box interface and the third box interface can be forced to be ejected, and finally ensure an effective and stable open state. Therefore, the movable arm can be a clamping plate structure which can vertically lift relative to the cleaning workbench, and can also be a rotary arm structure shown in fig. 5, and the opening, closing and clamping relative to the cleaning workbench can be realized through rotary motion.
