DETAILED DESCRIPTION

[0020] Reference is made to FIG. 1 through FIG. 11. A feeding system according to an embodiment of the present disclosure comprises a receiving container 1 and a feeding container 2.

[0021] The receiving container 1 comprises a receiving container body 11, a top cover 12 covering an upper end of the receiving container body, and a feeding connector 13. The feeding connector 13 is substantially tubular, the feeding connector 13 is connected with the top cover 12, and the feeding connector 13 is provided with a feeding channel 130 communicated with the receiving container body 11.

[0022] The feeding container 2 comprises a feeding container body 21 and a neck portion 22. An upper end of the neck portion 22 is connected with the feeding container body 21, and a lower end of the neck portion 22 has an outlet 23. The feeding container 2 is provided with a seal 24 which seals the outlet 23. The seal 24 preferably employs a film-like seal which for example may be made of an aluminum foil film. The neck portion 22 of the feeding container 2 is rotatably mounted in the feeding channel 130 of the feeding connector 13. A side of the neck 22 is provided with a guide slot 221. A sidewall of the feeding channel 130 is provided with a guide lug 131 mating with the guide slot 221. The guide lug 131 extends into the guide slot 221. The guide slot 221 is shaped in a way of guiding the feeding container 2 to move downward from an initial position when the feeding container 2 rotates in a predetermined direction due to the action of an external force. The number of guide lug 131 may be one or more. When the number of the guide lugs 131 is plural, the plurality of guide lugs 131 mate with the plurality of guide slots 221 in one to one correspondence.

[0023] In the present embodiment, the guide slot 221 comprises a first displacement slot 2211, a skewed slot 2213 and a second displacement slot 2212. The first displacement slot 2211 is parallel to the second displacement shot 2212, an end of the skewed slot 2213 is connected with the first displacement slot 2211, and the other end of the skewed slot 2213 is connected with the second displacement slot 2212.

[0024] Preferably, a plurality of first displacement slots 2211 mating with the plurality of guide lugs 131 respectively are all located at a first circumference, and a plurality of second guide slots 2212 corresponding to the plurality of guide lugs 131 are all located at a second circumference. In the present embodiment, the number of the guide lugs 131 is two.

[0025] The feeding connector 13 is provided with a seal destruction portion. The seal destruction portion is used to destruct the seal 24 while the feeding container 2 is moving downward, so that the material in the feeding container 2 flows into the receiving container body 11 through the outlet 23 of the neck portion 22.

[0026] In the example shown in FIG. 3 through FIG. 11, the seal destruction portion is comprised of a plurality of splitting portions 14a which split the seal 24. In the figures, the feeding connector 13 is provided with a base plate 133a, a circumference of which is connected with the sidewall of the feeding channel 130. The base plate 13a is provided with a central through hole 135a, and a bottom end of the plurality of splitting portions 14a are connected with a wall of the central through hole 135a.

[0027] In other embodiments, as shown in FIG. 12 and FIG. 13, the seal destruction portion may be comprised of a hollowed tapered portion 14b, and a bottom of the tapered portion 14b is connected with the sidewall of the feeding channel 130 of the feeding connector 13.

[0028] FIG. 3 through FIG. 6 show a working process in which the seal destruction portion destructs the seal 24. In FIG. 3, the feeding container 2 is at an initial position. At this time, the two guide lugs 131 are respectively located in the first displacement slot 2211 corresponding thereto, and the splitting portion 14a does not contact the seal 24. Since the two guide lugs 131 are spaced apart by 180, the figures can only display one of the guide lugs 131. As shown in FIG. 4, when the feeding container 2 rotates in a predetermined direction (clockwise direction in FIG. 4) due to the action of an external force, the two guide lugs 131 respectively move along the first displacement shots 2211 to an end of the corresponding skewed slots 2213 at first, whereupon the splitting portion 14a still does not contact the seal 24. As shown in FIG. 5, the feeding container 2 continues to rotate in the clockwise direction, and the two guide lugs 131 move upward along the corresponding skewed slots 2213, i.e., the feeding container 2 moves downward. In this process, the plurality of splitting portions 14a contact and split the seal 24, such that the material in the feeding container 2 flows through the outlet 23 of the neck portion 22 into the receiving container body 11. If the seal destruction portion is comprised of the hollowed tapered portion 14b, a top end of the tapered portion 14b punctures the seal 24 while the two guide lugs 131 is moving upward along the corresponding skewed slots 2213. As shown in FIG. 6, as the feeding container 2 continues to rotate, the two guide lugs 131 move from the other end of the corresponding skewed slots 2213 into the second displacement slot 2212, whereupon the feeding container 2 will not move downward any longer.

[0029] In a specific application, the receiving container body 11 of the feeding system according to an embodiment of the present disclosure is a liquid waste collection bag, and the top cover 12 is sealingly connected with a top portion of the liquid waste collection bag. The top cover 12 is provided with a connector pipe 121 running through the top cover and extending upward. The feeding connector 13 is inserted in the connector pipe 121, and a periphery of the upper end of the feeding connector 13 is sealingly connected with the upper end of the connector pipe 121. The feeding container 2 is a feeding bottle, and the material in the feeding container 2 is a solidifier. To ensure that the feeding system retains sealed when the liquid waste is collected under a negative pressure and material can be fed to the liquid waste when the liquid waste in the receiving container 1 is in a sealed and isolated state from the external, thereby reducing the risk of the secondary pollution and improving safety of the feeding operation, the outside surface of the neck portion 22 of the feeding container 2 sealingly engages with the sidewall of the feeding channel 130 of the feeding connector 13. In the present embodiment, a sealing ring 25 is provided around the outside surface of the neck portion 22, and the sealing ring 25 sealingly abuts against the sidewall of the feeding channel 130. It can be seen from FIG. 3 through FIG. 6 that in the whole rotation process and downward movement process of the feeding container, the sealing ring 25 is in a state of sealingly abutting against the sidewall of the feeding channel 130.

INDUSTRIAL APPLICABILITY

[0030] The feeding system according to an embodiment of the present disclosure has less components whose structures and shapes are uncomplicated, and thus those components are easy to manufacture. When the material needs to be fed, as long as the feeding container is rotated in a predetermined direction, the feeding container will move downward under the guidance of the guide slot and the seal destruction portion will destruct the seal with the movement of the feeding container, such that the feeding can be operated in a convenient manner.
