The ratio of the sum of the surface areas of the spraying holes 18 to the sum of the surface areas of the pressurizing holes 17 is set to be 0.8, so that the throughput of the fluid of the spraying holes 18 is smaller than that of the pressurizing holes 17, and part of spraying liquid is accumulated in the inner cavity of the sprayer housing 16, so that the pressure of the spraying liquid passing through the spraying holes 18 is increased, the impact pressure and the flow speed of the spraying liquid sprayed out from the spraying holes 18 are improved, and the spraying and washing efficiency and the spraying and washing effect on the endoscope are further improved.
Further, along the flowing direction of the fluid, the spray liquid pipe 4, the lifting cylinder 9, the pressurization pipe 13, the pressurization hole 17, the inner cavity of the sprayer shell 16 and the spray hole 18 are communicated in sequence. In the process of injecting the spray liquid into the cleaning and disinfecting tank 1 for spraying and washing, the spray liquid entering from the spray liquid pipe 4 sequentially passes through the lifting cylinder 9, the booster pipe 13, the booster hole 17 and the inner cavity of the nozzle shell 16, and is finally sprayed out to the endoscope in the cleaning and disinfecting tank through the spray hole 18, so that the washing of the endoscope is realized.
Further, the pipe diameter of the lifting cylinder 9 is larger than that of the pressure increasing pipe 13. Through setting up the pipe diameter of a section of thick bamboo 9 to be greater than the pipe diameter of booster pipe 13, carrying out the in-process that the washing liquid sprayed, help increasing the impact pressure of spraying liquid to booster pipe 13, realize that the shower nozzle subassembly stretches out from the shower nozzle indoor fast in the short time.
Further, the elastic member 12 serves to push the upper confinement ring 10 to move close to the shower pipe 4. When the spray liquid is not introduced into the spray liquid pipe 4, the elastic member 12 exerts a force on the upper limit ring 10, so that the nozzle assembly is held in the nozzle chamber 8.
When in use, when the endoscope needs to be cleaned and disinfected, the endoscope is firstly placed in the cleaning and disinfecting tank 1, then the tank cover 2 is closed, cleaning liquid is injected into the cleaning and disinfecting tank 1 through the cleaning liquid pipe 4, the cleaning liquid enters the pressure increasing pipe 13 through the lifting cylinder 9, because the bottom of the pressure increasing pipe 13 is sealed, and the pressure increasing hole 17 is arranged on the side wall of the pressure increasing pipe 13, the pressure increasing pipe 13 can generate flow resistance to the cleaning liquid, the pressure of the cleaning liquid in the pressure increasing pipe 13 and the lifting cylinder 9 is increased, meanwhile, under the continuous impact of the cleaning liquid on the pressure increasing pipe 13, the pressure increasing pipe 13 is forced to overcome the resistance generated by the elastic piece 12 to move downwards, finally the nozzle assembly is extended out, the distance between the nozzle assembly and the endoscope is shortened, on the other hand, because the nozzle housing 16 is restrained by the restraining piece 15 and is hung on the fixed rotating shaft 14, and the rotating cylinder 19 in the nozzle housing 16 can rotate in cooperation with, in the process that the cleaning liquid flows along the spraying holes 18, the spraying holes 18 obliquely surround the structure to enable the sprayed cleaning liquid to have reaction force on the spray head shell 16, and under the cooperation of the spraying holes 18, the spray head shell 16 continuously rotates in the process that the spraying holes 18 continuously spray the spraying liquid, so that the cleaning liquid is rotatably sprayed, the cleaning liquid sprayed by the spray head assembly is enabled to be sprayed at high pressure on the inner mirror in a short distance and in a rotating spraying and flushing mode, and the cleaning efficiency of the inner mirror is improved; and after the washing is accomplished, stop the injection of washing liquid, because the washing liquid disappears to the impulse pressure of booster pipe 13, under the effect of elastic component 12, make shower nozzle subassembly shrink to hide in shower nozzle room 8, then scope cleaning and disinfecting equipment just can be to the washing disinfection inslot 1 in the injection antiseptic solution, utilize the antiseptic solution to carry out the disinfection of full immersion formula to the scope, effectively avoid the antiseptic solution to adhere to the problem production that spray set caused the unable complete recovery of antiseptic solution simultaneously, improve scope cleaning and disinfecting effect.
The foregoing is illustrative of the preferred embodiments of this invention, and it is to be understood that the invention is not limited to the precise form disclosed herein and that various other combinations, modifications, and environments may be resorted to, falling within the scope of the concept as disclosed herein, either as described above or as apparent to those skilled in the relevant art. And that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
