The guide groove 32 is shaped to guide the charging container 3 to move downward from an initial height to a final height when the charging container 3 is rotated in a predetermined direction by an external force.

In the present embodiment, the guide groove 32 includes a first translation groove 325, a diagonal groove 327, and a second translation groove 326. The first translation groove 325 and the second translation groove 326 are parallel to each other, and one end of the inclined groove 327 is connected to the first translation groove 325, and the other end of the inclined groove 327 is connected to the second translation groove 326. The two first translational grooves 325 respectively engaged with the two guide protrusions 24 are both located on the first circumference, and the two second translational grooves 326 respectively corresponding to the two guide protrusions 24 are both located on the second circumference.

In other embodiments, the number of guide projections 24 may be more than two, such as three, four, etc. When the number of the guide projections 24 is two or more, the two or more guide projections 24 are fitted with the two or more guide grooves 32, respectively, in a one-to-one correspondence. In order to allow the charging container 3 to move a greater distance when it is rotated in a predetermined direction, each set of guide slots 32 may be provided with more than two translation slots, with a chute being connected between each adjacent two translation slots. The guide cams 24 are located in the lowermost translatory groove when the charging container 3 is at the initial height and the guide cams 24 are located in the uppermost translatory groove when the charging container 3 is at the final height.

In another embodiment, the side of the lower end of the charging container is provided with a set of guide grooves, and the side wall of the charging channel is provided with guide projections corresponding to the guide grooves, and the guide projections extend into the guide grooves. The guide groove is shaped to guide the charging container to move downward from an initial height to a final height when the charging container is rotated in a predetermined direction by an external force, and to guide the charging container to rotate relative to the cutting portion when the charging container is at the final height.

The top cover 2 is provided with a cutting portion 25, the cutting portion 25 is used for puncturing the seal 34 during the process of moving the charging container 3 from the initial height to the final height, and for cutting the seal 34 during the relative rotation between the charging container 3 after puncturing the seal 34, so that the material in the charging container 3 flows into the receiving container 1 through the discharge hole 33.

In the present embodiment, the number of the cut portions 25 is three, the three cut portions 25 are disposed on the sidewall of the charging channel 230 at intervals along the same circumference, and the central angle corresponding to the circular arc between every two adjacent cut portions is the included angle of the cut portion. Wherein the angle of the largest cut portion is less than or equal to 180 degrees. In other embodiments, the number of the cut portions 25 may be one, two, or three or more. For the plurality of cut portions 25 (two or more cut portions), the plurality of cut portions 25 are disposed at non-uniform intervals along the same circumference, and the largest cut portion angle (i.e., the central angle corresponding to the circular arc between two adjacent cut portions having the largest interval) is not more than 180 °.

The external feeding system is also provided with a limiting structure which is used for limiting the relative rotation angle between the cutting part 25 and the feeding container 3 when the seal 34 is cut. When the number of the cutting parts 25 is one, the limiting structure is used for limiting the relative rotation angle between the cutting parts 25 and the charging container 3 when the sealing opening 34 is cut by the cutting parts 25 to be less than 360 degrees, and allowing the relative rotation angle between the cutting parts 25 and the charging container 3 when the sealing opening 34 is cut by the cutting parts 25 to be more than or equal to 180 degrees; when the number of the cutting portions 25 is multiple, the limiting structure is used for limiting the relative rotation angle between each cutting portion 25 and the charging container 3 when the seal 34 is cut by each cutting portion 25 to be smaller than the maximum cutting portion included angle, and allowing the relative rotation angle between each cutting portion 25 and the charging container 3 when the seal 34 is cut by each cutting portion 25 to be larger than or equal to the second maximum cutting portion included angle.

Taking the example of fig. 7 as an example, in the three cut portions 25, the central angle B corresponding to the circular arc between two adjacent cut portions closest to each other is 90 °, the central angle a corresponding to the circular arc between two adjacent cut portions farthest from each other is 180 °, and the central angle corresponding to the circular arc between the remaining two adjacent cut portions is 90 °, so that the limit structure limits the relative rotation angle between each cut portion and the charging container 3 when each cut portion cuts the seal 34 to be less than 180 °, and allows the relative rotation angle between each cut portion 25 and the charging container 3 when each cut portion cuts the seal 34 to be greater than or equal to 90 °.

The limiting structure includes an end position stopping portion 361 disposed in the uppermost translation groove of each set of guide grooves, and the end position stopping portion 361 is used for stopping the corresponding guide protrusion 24. The central angle of the upmost translation groove in each group of guide grooves corresponding to the circumferential direction is larger than 180 degrees and smaller than 360 degrees. To do this, it is sometimes necessary that a portion of the uppermost translation slot of the plurality of sets of guide slots overlap each other, and the plurality of guide projections 24 share one end stop 361. Since when one guide projection 24 is stopped by the end stop 361, the other guide projections 24 cannot rotate any more.

Optionally, the side wall of the uppermost translational slot is provided with a stop protrusion 371 at a position close to the stop 361, and the stop protrusion 371 is used for stopping the relative movement of the guide protrusion 24 towards a direction away from the stop 361 when the guide protrusion 24 is located between the stop 361 and the stop protrusion 371, so as to keep the charging container 3 at the stop position, i.e. the position of the guide protrusion 24 between the stop 361 and the stop protrusion 371.

Optionally, the lowest translational slot in each set of guide slots is provided with a start position stop 362, the sidewall of the lowest translational slot is provided with a start position blocking protrusion 372 at a position close to the start position stop 362, the start position blocking protrusion 372 is used for blocking the guide projection 24 from moving relatively in a direction away from the start position stop 362 when the guide projection 24 is located between the start position stop 362 and the start position blocking protrusion 372, so as to keep the charging container 3 at the start position, and prevent the external charging system from rotating the charging container 3 relative to the cutting part 25 during transportation, and the start position of the charging container 3 is the position when the guide projection 24 is located between the start position stop 362 and the start position blocking protrusion 372.

The lower side wall of the lowermost translation slot of each set of guide slots is provided with a guide projection mounting entrance 38 at a position close to the start position stop projection 372. The width of the guide bump assembly inlet 38 gradually increases from top to bottom, the width of the upper end of the guide bump assembly inlet is less than or equal to the width of the guide bump 24, the width of the lower end of the guide bump assembly inlet is greater than or equal to the width of the guide bump 24, the bottom surface of the guide bump assembly inlet 38 gradually inclines inwards (i.e., the diameter is gradually smaller and smaller) from top to bottom to form an inclined surface, the guide bump 24 forms interference fit with the bottom surface of the guide bump assembly inlet 38 when being positioned at the upper end of the guide bump assembly inlet 38, and the guide bump 24 forms clearance fit with the bottom surface of the guide bump assembly inlet 38 when being positioned at the lower end of the guide bump assembly inlet 38, so that the guide bump 24 can be conveniently installed in the guide groove, and the guide bump 24 installed in the guide. Since the guide projection 24 is restricted by the guide projection fitting inlet 38 in all three directions when it is positioned at the upper end of the guide projection fitting inlet 38, the charging container cannot fall off the guide projection without a large external force, thereby improving the safety and reliability of the external charging system during transportation.

Fig. 8 to 11 show the operation of the cutting part 25 to cut the seal 34 in this embodiment.

In fig. 8, the charging container 3 is in an initial position and at the same time at an initial height. At this time, the two guide projections 24 are respectively positioned in the corresponding first translation grooves 325, and the cut portion 25 does not contact the seal 34. Since the two guide cams 24 are spaced apart by 180 °, only one of the guide cams 24 is visible in the figure. As shown in fig. 9, when the charging container 3 is rotated in a predetermined direction (clockwise direction in fig. 9) by an external force, the two guiding protrusions 24 first move to one end of the corresponding inclined groove 327 along the corresponding first translation groove 325, respectively, and the cut-off portion 25 still does not touch the seal 34. As shown in fig. 10, continuing to rotate the feed container 3 in a clockwise direction, the two guide projections 24 move up the respective corresponding chutes 327, i.e. the feed container 3 moves down, during which the plurality of cut-outs 25 contact and puncture the seal 34. As the feed container 2 continues to rotate, the two guide cams 24 move from the other end of the respective chute 327 into the second translational groove 326, as shown in fig. 11, at which point the feed container 3 reaches a final height and can no longer move downwards. The two guide protrusions 24 rotate in the second translational groove 326 until one of the guide protrusions 24 passes over the end stop protrusion 371 and is stopped by the end stop 361. At this time, the seal 34 is cut by more than 180 degrees in the circumferential direction, so that the material in the charging container 3 can be ensured to flow into the receiving container 1 through the discharge port 33, meanwhile, the seal 34 is not completely cut in the circumferential direction, and a part of the seal is connected with the charging container 3, so that the seal 34 cannot fall into the receiving container 1.

In a specific application, according to the utility model discloses plus material system's of first embodiment material receiving container 1 is medical waste liquid collecting vessel, and medical waste liquid collecting vessel includes barrel 1a and waste liquid collecting bag 1b, and waste liquid collecting bag 1b sets up in barrel 1 a. The top cover 2 is hermetically connected with the top of a waste liquid collecting bag 1b of the medical waste liquid collecting cylinder and covers the opening part of a cylinder body 1a of the medical waste liquid collecting cylinder. The feeding container 3 is a feeding bottle, and the material in the feeding container 3 is a coagulant.

In order to ensure that the external feeding system keeps sealed when used for collecting waste liquid under negative pressure and can ensure that the waste liquid in the receiving container 1 is fed to the waste liquid in a sealed and isolated state with the outside, thereby reducing the risk of secondary pollution and improving the safety of feeding operation, the outer side surface of the feeding container 3 is in sealed fit with the side wall of the feeding channel 230 of the feeding joint 23. In this embodiment, a sealing ring groove 39 is sleeved on the outer side surface of the charging container 3, a sealing ring 4 is arranged in the sealing ring groove 39, and the sealing ring 4 is in sealing fit with the side wall of the charging channel 230.
