Referring to fig. 1, 2, 3 and 4, a method for separating and combining a traditional Chinese medicine delivery nozzle and a traditional Chinese medicine bottle during traditional Chinese medicine filling is provided, the traditional Chinese medicine delivery nozzle is designed to be composed of an inner delivery pipe 4 and a sleeve 5 sleeved on the inner delivery pipe, a traditional Chinese medicine bag 40 stops under the traditional Chinese medicine delivery nozzle, the traditional Chinese medicine delivery nozzle extends to be inserted into a bag opening 41 of the traditional Chinese medicine bag by separating the inner delivery pipe and the sleeve, the inner delivery pipe and the sleeve are folded to enable the traditional Chinese medicine delivery nozzle to be pulled out of the bag opening of the traditional Chinese medicine bag, the traditional Chinese medicine delivery nozzle is opened when the inner delivery pipe and the sleeve are separated, and the traditional Chinese medicine delivery nozzle is closed when the inner delivery pipe and the sleeve are folded.
Specifically, the traditional Chinese medicine delivery nozzle comprises an inner delivery pipe 4 and a sleeve pipe 5 which is sleeved on the inner delivery pipe in a vertically movable manner. The upper end of the inner conveying pipe is provided with an external thread section 6. The inner conveying pipe is provided with a sealing step 7 positioned below the outer thread section. An inner conveying pipe sealing washer 8 sleeved on the outer thread section is arranged on the sealing step. When the device is used, the inner conveying pipe is connected into the traditional Chinese medicine solution output port 1 of the traditional Chinese medicine storage barrel 2 through the external thread section, and the sealing step is matched with the traditional Chinese medicine storage barrel to clamp the sealing washer of the inner conveying pipe part so that the inner conveying pipe is connected with the traditional Chinese medicine solution output port in a sealing mode. The upper end of the peripheral surface of the inner conveying pipe is provided with a jack 9. The lower end surface of the inner conveying pipe is provided with an annular sliding groove 10 extending along the circumferential direction of the inner conveying pipe. The annular sliding groove is provided with a large-diameter section 11. A hanging step 12 is formed between the lower end of the large-diameter section and the annular sliding groove. The annular sliding groove is provided with a sealing vertical pipe 13 in a sealing and sliding mode. The upper end of the sealing vertical pipe is provided with an outward flange 14. The flanging is positioned in the large-diameter section. The outward flange and the hanging step form a drop-proof structure 15 for preventing the sealing vertical pipe from dropping out of the annular sliding groove. And a pressing spring 16 for driving the seal vertical pipe to extend out of the annular sliding groove is arranged in the annular sliding groove. And a suspension ring 17 extending along the circumferential direction of the seal vertical pipe is arranged on the outer circumferential surface of the seal vertical pipe. The peripheral surface of the suspension ring is provided with a sealing groove 18 extending along the circumferential direction of the suspension ring. The generating line of seal groove is the circular arc line. The opening width of the sealing groove is smaller than the diameter of a circle where the arc line is located. A sealing ring 20 with a circular cross section is arranged in the sealing groove. The suspension ring and the sleeve are connected together in a sealing mode through the sealing ring. The suspension ring is provided with an annular scraper 21 extending axially along the suspension ring and abutting against the inner circumferential surface of the sleeve. The inner peripheral surface 22 of the annular scraper is a tapered surface having a large upper end and a small lower end. A volume-expanding groove 23 is formed between the hanging step, the seal riser and the sleeve. The sleeve is provided with a sealing cover 24 which is matched with the sealing vertical pipe to seal the inner conveying pipe. A plurality of liquid medicine output channels 25 positioned outside the sealing vertical pipe are arranged between the sealing cover and the sleeve. The upper end of the liquid medicine output channel is aligned with the expansion groove along the up-down direction. The upper surface of the sealing cover is provided with a sleeve part sealing gasket 26 which is matched with the end surface of the sealing vertical pipe to connect the sealing vertical pipe and the sealing cover together in a sealing way. The part of the sleeve below the sealing cover is provided with an upper cylindrical section 27, a conical section 28 with a large upper end and a small lower end and a lower cylindrical section 29 which are sequentially distributed from top to bottom. A step surface 30 is formed between the upper cylindrical section and the conical section. The opening direction of the lower end of the liquid medicine output channel is aligned with the step surface. The inner diameter of the lower cylindrical section is equal to the inner diameter of the lower end of the conical section. The inner peripheral surface of the sleeve is provided with an insertion hole 31. A bolt 32 and a bolt ejection spring 33 for driving the bolt to extend out of the jack are arranged in the jack in a penetrating way. The latch is connected to a pull rod 34 which extends out of the sleeve and drives the latch to retract into the socket. A stopper ring 35 protruding from the sleeve and extending in the circumferential direction of the sleeve is provided on the outer circumferential surface of the sleeve. The pull rod extends out of the peripheral surface of the sleeve through the baffle ring. The outer end of the pull rod is provided with a push block 36 which extends downwards beyond the stop ring. A supporting slot 37 is enclosed between the push block and the sleeve. The surface 38 of the portion of the pusher forming the wall of the spreader slot is a beveled surface with the upper end sloping in the direction of approaching the sleeve. When the bolt is arranged in the jack sleeve in a penetrating way, the sealing cover is in sealing butt joint with the sealing vertical pipe, so that the inner conveying pipe is in a closed state. When the bolt is hung on the suspension ring, the sealing cover is separated from the sealing vertical pipe, so that the inner conveying pipe is in an open state.
When in use, the mouth 41 of the Chinese medicine bag 40 is aligned with the sleeve along the up-down direction. Then the hand is held on the sleeve and positioned in the opening groove, the pushing block is extruded by the hand, and the pull rod is pulled by the pushing block to enable the bolt to be separated from the jack. When the sleeve is moved downwards to the sleeve insertion bag opening, the inner conveying pipe part is opened, so that the traditional Chinese medicine solution in the traditional Chinese medicine storage barrel flows into the traditional Chinese medicine bag. When the traditional Chinese medicine bag needs to be removed after filling, the sleeve is moved upwards to a position where the sleeve cannot move continuously, the bolt is aligned with the jack at the moment, the bolt is inserted into the jack under the action of the bolt ejecting spring, the sleeve rises to be positioned outside the traditional Chinese medicine bag at the moment, the inner conveying pipe is closed, and finally the traditional Chinese medicine bag is removed.
