The top nozzle 451 is installed on the top of the cabinet 1 and above the corresponding placement bracket 3. , And the top nozzle 451 is provided in at least one row, and there are two rows in the embodiment of the figure. The side wall sprinkler 452 is installed on the inner side wall of the cabinet 1 and is located above the corresponding placing bracket 3, and the side wall sprinkler 452 is arranged at least one row above the corresponding placing bracket 3. In this figure There are two rows in the embodiment. The spray head 45 adopts a high-pressure spray head that can spray a dispersed water column, which can uniformly and efficiently clean the medical equipment under it. The nozzle 45 is connected to the outlet of the water pump 43 through a water pipe 44, and the water pipe 44 adopts a hidden design in the section connecting the nozzle 45 and the water pump 43, and is installed inside the cavity 11 of the cabinet 1, which not only improves the service life of the water pipe , And can increase the overall aesthetics. The ultraviolet sterilization light source 5 is located on the top of the inside of the cabinet 1 and is electrically connected to the controller 8. The ultraviolet sterilization light source 5 is installed inside the sealed high temperature and high pressure resistant glass 51 to avoid the high temperature and high pressure steam environment from giving the ultraviolet sterilization light source 5 The damage caused. The electric steam generator 6 includes a steam generator body 61 and a steam delivery pipe 62. The steam generator body 61 is installed on the back side wall of the outer layer of the cabinet 1, and is electrically connected to the controller 8. The steam inlet end is connected to the steam outlet of the steam generator body 61, and the steam outlet end of the steam delivery pipe 62 is connected to the cabinet 1 from both sides of the cabinet 1 and communicates with the inside of the cabinet 1 for conveying large quantities High temperature steam. The sewage system 7 includes a sewage collection tank 71, a sewage pipe 72 and a sewage collection tank 73. The sewage collection tank 71 is installed at the bottom of the cabinet 1, and the sewage collection tank 71 adopts a design method of sloping all around to the center. This design is convenient Sewage gathers in the middle to facilitate sewage discharge. The sewage collection tank 71 is equipped with a dirt filter 711 above the outlet located in the center, which can filter some large-volume dirt and avoid clogging of the sewage pipe 72. The dirt filter 711 is removable. design. The sewage collection tank 71 is connected to the sewage collection tank 73 through a sewage pipe 72, and a sewage electromagnetic control valve 712 is installed at the outlet of the sewage collection tank 71. The sewage electromagnetic control valve 712 can prevent steam from overflowing from the sewage pipe 72 when it is closed. The sewage electromagnetic control valve 712 is electrically connected to the controller 8. The controller 8 is installed on the outer side of the cabinet 1.

[0028] Figure 4 It is a block diagram of the control principle of the present invention, such as Figure 4 As shown, the controller 8 includes a control adjustment button 81, a control module 82, a timer 83, and a single-chip processor 84. The control adjustment button 81 is connected to the control module 82. By controlling the adjustment button 81, the working time under different processes and related Set up. The control module 82 is connected to the single-chip processor 84, and the timer 83 is bidirectionally connected to the single-chip processor 84, which can time the working process of the single-chip processor 84. The single-chip processor 84 is respectively connected to the aseptic water tank electromagnetic control valve 411, the cleaning liquid tank electromagnetic control valve 421, the water pump 43, the ultraviolet sterilization light source 5, the electric steam generator main body 61 and the sewage electromagnetic control valve 712, for controlling the power off And turn on.

[0029] Working principle: The staff sets the relevant values, the controller 8 first controls to open the cleaning liquid tank electromagnetic control valve 421, and at the same time opens the water pump 43, at this time, the nozzle 45 sprays the cleaning liquid to clean the medical equipment, and the process is over Then, the controller 8 controls the solenoid control valve 421 of the cleaning liquid tank to close, and at the same time opens the solenoid control valve 411 of the aseptic water tank, the nozzle 45 sprays sterile water to rinse the medical instruments. After this process is over, the controller 8 controls to close The aseptic water tank electromagnetic control valve 411 and the water pump 43 are turned on at the same time to turn on the ultraviolet sterilization light source 5 to perform ultraviolet sterilization on medical equipment. After this process, the controller 8 turns off the ultraviolet sterilization light source 5 and closes the sewage electromagnetic control valve 712 at the same time, and then turns on The main body 61 of the electric steam generator performs high-temperature steam sterilization on medical instruments. After completion, the main body 61 of the electric steam generator is controlled to close, and the entire cleaning and disinfection process ends.

[0030] The above are only the preferred embodiments of the present invention, and do not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still valid.
