The utility model can adapt to different sizes of infusion ports through the flexible cone pipe 21, and can automatically adjust the tightness according to the specification of the infusion port by cooperating with the take-up ring 22 and the inflation tensioning piece 23, so as to realize multi-specification filling, without frequent replacement of the filling device, improve production efficiency, and reduce equipment cost.
[0020] The implementation principle is that the flexible cone pipe 21, as the part directly contacting with the infusion port, has a certain elasticity and can adapt to different sizes of infusion ports. The tightening ring 22 is sleeved outside the folding end of the flexible cone pipe 21, and the flexible cone pipe 21 is better fitted to the infusion port through the tightening effect. The inflatable tensioning member 23 expands after inflation, applies pressure to the flexible cone pipe 21, further enhances the sealing performance and holding effect, and ensures that different specifications of infusion ports can achieve good sealing and stable filling. The flexible cone pipe 21: the material can be selected from silica gel, which has good flexibility and chemical stability. The outer diameter of the tapered pipe part 211 can be designed to be 10-50 mm according to the common infusion port specifications, the length of the straight pipe part 212 is 30-80 mm, and the wall thickness is 2-5 mm.
[0021] The tightening ring 22: the material can be selected from stainless steel, the inner diameter is matched with the outer diameter of the straight pipe part 212 of the flexible cone pipe 21, for example, for the case that the outer diameter of the straight pipe part 212 of the flexible cone pipe 21 is 20 mm, the inner diameter of the tightening ring 22 can be designed to be 20-21 mm to achieve appropriate tightening effect.
[0022] The inflatable tensioning member 23 (elastic inflatable interlayer 3): the material can be selected from rubber, the thickness is 5-10 mm, there is a gap of 2-5 mm between the inflatable tensioning member 23 and the outer shell 1 and the flexible cone pipe 21 when not inflated, and the pressure can reach 0.2-0.5 MPa after inflation to ensure sufficient tension.
[0023] The flexible cone pipe 21 is composed of a tapered pipe part 211 and a straight pipe part 212, the tapered pipe part 211 extends out of the outer shell 1 and is threadedly fixed, the flexible cone pipe 21 is designed as a combination of the tapered pipe part 211 and the straight pipe part 212, the tapered pipe part 211 extends out of the outer shell 1 and is threadedly fixed, the installation of the flexible cone pipe 21 is more stable, which is convenient for connecting with the infusion port, at the same time, the coaxiality of the flexible cone pipe 21 and the outer shell 1 is ensured, the filling precision and stability are improved, and the extension direction of the flexible cone pipe 21 and the extension direction of the outer shell 1 are located on the same vertical extension line.
[0024] The implementation principle is that the tapered pipe part 211 extends out of the outer shell 1 and is threadedly fixed, the reliable fixation of the flexible cone pipe 21 and the outer shell 1 is realized through threaded connection, and it is ensured that the flexible cone pipe 21 will not loosen or shift during filling. At the same time, the extension direction of the flexible cone pipe 21 and the extension direction of the outer shell 1 are located on the same vertical extension line, the filling liquid flows smoothly in the device, the liquid residue and turbulence in the device are reduced, the filling quality is improved, the flexible cone pipe 21: the length of the tapered pipe part 211 is 20-50 mm, and the taper can be designed to be 1:5-1:10 according to actual needs. The thread specification can be selected from M10-M20 metric threads, which are matched with the corresponding thread holes on the outer shell 1.
[0025] The tightening ring 22 is arranged on the straight pipe part 212. Arranging the tightening ring 22 on the straight pipe part 212 can more accurately tighten the straight pipe part 212 of the flexible cone pipe 21, improve the fit of the flexible cone pipe 21 with the infusion port, enhance the sealing effect, and further prevent leakage.
[0026] Principle: The straight pipe part 212 is more regular in shape relative to the cone pipe part 211. Arranging the tightening ring 22 here can more evenly distribute the tightening force on the straight pipe part 212, so that the flexible cone pipe 21 better fits the infusion port in the area of the straight pipe part 212, reducing the risk of leakage due to poor fit.

[0029] Principle: The elastic inflatable interlayer 3 is arranged between the housing 1 and the flexible cone pipe 21. When the elastic inflatable interlayer 3 is inflated through the inflation nozzle 4, the elastic inflatable interlayer 3 expands and exerts pressure on the flexible cone pipe 21, making the flexible cone pipe 21 more tightly fit the infusion port. According to the specifications of the infusion port and the filling requirements, the expansion degree of the elastic inflatable interlayer 3 can be adjusted by controlling the inflation amount, thereby accurately controlling the tensioning force of the flexible cone pipe 21.
[0030] Product model and data information: The inflation nozzle 4 of the elastic inflatable interlayer 3 can be selected as a quick connector with specifications such as φ6-φ10 for easy connection with inflation equipment. The expansion amount of the elastic inflatable interlayer 3 after inflation can be designed according to the gap size between the flexible cone pipe 21 and the housing 1, and the expansion amount is generally between 3-8 mm.
[0031] The deflation valve 5 provided on the elastic inflatable interlayer 3 extends outside the housing 1. The deflation valve 5 provided on the elastic inflatable interlayer 3 extends outside the housing 1, which can timely release the gas in the elastic inflatable interlayer 3 when needed, avoid device damage or safety hazards due to excessive pressure, and improve the safety and reliability of the device.
[0032] Principle: During the filling process, if the pressure in the elastic inflatable interlayer 3 is too high, it may cause excessive pressure on the flexible cone tube 21 and the shell 1, resulting in damage to the device or affecting the filling quality. By setting the air release valve 5, when the pressure exceeds the set value, the air release valve 5 automatically opens, releasing excess gas, keeping the pressure in the elastic inflatable interlayer 3 within a safe range.
[0033] Product model and data information: Air release valve 5: spring type air release valve 5 can be selected, the opening pressure can be set to 0.3-0.6MPa according to actual demand. The interface specification of the air release valve 5 matches the interface specification of the inflatable mouth 4 of the elastic inflatable interlayer 3, such as φ6-φ10.
[0034] Both ends of the shell 1 are provided with threads, which facilitates the connection and installation of the filling device with other equipment or pipelines, improves the versatility and scalability of the device, and facilitates use in different production environments.
[0035] Principle: Threaded connection is a common and reliable connection method, the threads at both ends of the shell 1 can cooperate with the corresponding threaded holes on other equipment or pipelines, and the shell 1 can be quickly connected and fixed by rotating. This connection method is simple to operate, firm in connection, and can meet the needs of different production processes.
[0036] Product model and data information: Shell 1: The material can be selected from stainless steel to ensure the strength and corrosion resistance of the device.
