It is understood that in the present embodiment, the connector 321 is fixedly connected to the bag 31, and in other embodiments of the present application, the connection relationship between the connector 321 and the bag 31 may be movably or detachably connected, so long as the overflow of the liquid at the joint of the connector 321 and the cover 322 can be avoided.

It should be understood that, in the present embodiment, the cover 322 is implemented to protrude from the connector 321, and of course, in other embodiments of the present application, the cover 322 may be implemented to be radially recessed from the connector 321, as long as the cover 322 can be used to open and close the feeding port 311 to avoid contamination of the liquid carried in the liquid dispensing bag 30.

The utility model mainly aims at the optimal design of the closed type disposable liquid dispensing bag material inlet limiting device, adopts a magnetic attraction mode to replace a mechanical locking mode, optimizes the operation steps of assembling and disassembling the closed type disposable liquid dispensing bag material inlet limiting device, and ensures that the operation is more convenient.

It will be appreciated that in embodiments of the present application, the automatic locking between the stoppers 20 is implemented by magnetic force to achieve the desired locking effect, although in other embodiments of the present application, the automatic locking between the stoppers 20 may be implemented by a bump, so long as the operator can use the liquid treatment system 200 conveniently.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The foregoing examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
