DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present application will be described below with reference to the embodiments, but the present application is not limited to these embodiments. Some specific details are described in detail in the following detailed description of the present application. For those skilled in the art, the present application may be understood without reference to these details. In order to avoid obscuring the essence of the present application, commonly known methods are not described in detail.



FIGS. 1 and 2 show the structure of the liquid storage container according to the present application. The liquid storage container comprises a first lid 1 and a container body 2, an interior of the container body and the lid forming a chamber, the container body 2 having an open end, an opening end of the first lid and an opening end of the container body 2 being rotatably and sealingly connected. The liquid storage container further comprises a first pipe 7 and a second pipe 8 communicating the chamber with the outside, wherein the first pipe 7 is provided on the first lid 1, and the second pipe 8 is provided on the container body. As a preferred embodiment, in FIG. 1 the first lid 1 and the container body 2 are threadedly and sealingly connected, but the connection is not limited to the manner as shown in FIG. 1, and may also be in the manner as shown in FIG. 4. In FIG. 4 a sealing ring 24 is provided between the first lid 1 and the container body 2, a threaded portion is provided externally on an end portion of the first lid 1, and a stopper boss 221 is provided on an outer circumference of the container body 2, a nut 23 is disposed on an outer circumference of the stopper boss 221 such that the stopper boss 221 limits a axial position of the nut, the nut 23 is threadedly connected to the threaded portion of the first lid 1, and the sealing connection between the first lid 1 and the container body 2 is effected by the sealing ring 24. The first lid 1 is rotatably fixed to the container body 2 by the nut 23 to effect a rotatable and sealing connection between the first lid 1 and the container body 2. The first lid 1 closes the opening of the container body 2, and a chamber is formed between the first lid 1 and the container body 2. By rotatable and sealing connection between the first lid 1 and the container body 2, the first pipe 7 provided on the first lid 1 and the second pipe 8 provided on the container body, a position of the first pipe 7 relative to the second pipe 8 is adjustable with rotation of the first lid 1, position for pipeline may be adjusted at any time according to the specific site condition, and it is very convenient to make such an adjustment, such that the connecting pipeline is very simple, a length of the pipeline is shortened, turning on the pipeline is reduced, allowing a smooth flow of a medium carried therein.


As one embodiment, the liquid storage container according to the present application further comprises a volume adjusting portion which, as shown in FIG. 3, is formed by a separator plate 6 and an adjusting screw 5. The separator plate 6 and the adjusting screw 5 may be formed integrally, or be formed separately but being assembled together. The separator plate 6 separates the chamber into a first chamber 9 and a second chamber 10, the first chamber and the second chamber being independently from one another and not in communication with one another, wherein the first chamber 9 serves as a liquid storage chamber and the second chamber 10 serves as an adjusting chamber. The first lid 1 is in shape of a cup comprising a bottom wall and a side wall. The separator plate 6 is provided inside the chamber. As shown in FIG. 1, in this embodiment, the separator plate 6 is provided inside the first lid 1 such that it is fitted with an inner wall of the side wall of the first lid. However, the arrangement of the separator plate is not limited to such a manner. In fact, it is also allowable to provide the separator plate 6 inside the container body 2 such that it is fitted with an inner wall of the container body 2. The adjusting screw 5 has an end coupled to the separator plate 6 and another end passing through an aperture in the first lid 1 to reach the outside of the liquid storage container. A threaded portion is provided between the adjusting screw 5 and the aperture formed in a bottom wall of the first lid 1. Rotation of the adjusting screw 5 causes an axial movement of the adjusting screw 5 relative to the first lid 1 so as to bring along therewith a movement of the separator plate 6 within the chamber. Preferably, the adjusting screw 5 is provided with a volume scale marking 51 corresponding to an actual volume of the liquid storage chamber therein, such that an operator is able to see clearly the adjustment condition of the volume of the interior, so as to effect an accurate volume adjustment. The adjusting screw 5 may be driven by a manual adjustment mechanism so as to be rotated manually, or may be driven by a drive mechanism, such as a motor or the like.


Besides the structure of the volume adjusting portion as shown in FIG. 1, as another preferred embodiment, the volume adjusting portion may be also be constructed as an elastic element to adjust a volume of the liquid storage chamber according to a pressure of the liquid storage chamber. As shown in FIG. 5, the adjusting mechanism comprises a separator 6, a guide mechanism and an elastic element. The guide mechanism may be a guide rail 12 or a slide rod, and the separator plate 6 may be provided with an engaging hole to cooperate with the guide rail 12 or the slide rod, such that the separator plate 6 is movable along the guide rail 12 or the slide rod within the chamber. The elastic element may comprise a spring 11 applying an elastic force to the separator plate 6 to move the separator plate 6. In such a manner, the volume of the liquid storage chamber may be adjusted according to the pressure of the liquid storage chamber. When there is a great pressure of the liquid storage chamber, the spring 11 is compressed, and the separator plate 6 is driven such that the liquid storage space becomes large; and when there is a small pressure of the liquid storage chamber, the spring 11 extends such that the liquid storage space becomes small.


In one embodiment, the container body 2 is provided with a connecting holder 4 configured to fix and mount the container body 2. The connecting holder may be connected by welding or by other means.


In one embodiment, as shown in FIG. 1, the separator plate 6 is arranged inside the first lid 1, and disposed between the bottom wall of the first lid 1 and the first pipe 7, such that the first pipe 7 does not need to pass through the separator plate 6 in which case an additional seal does not need to be provided at the aperture. In the case where the separator plate 6 is disposed on the container body 2, the first pipe 7 passes through the separator plate 6. Further, the second pipe 8 is provided on the container body 2. The second pipe 8 communicates the first chamber 9 with the outside. The first lid 1 is rotatable to vary a position of the first lid 1 relative to the container body 2, so as to vary a position of the first pipe 7 relative to the second pipe 8, thereby to meet the requirement for different pipeline connections. However, as the position of the connecting holder is usually fixed, the mounting position of the second pipe 8 may also be restricted, in which case only the position of the first pipe 7 is adjustable, and such an adjustment is not sufficiently flexible.


In this regard, as one embodiment, the container body 2 is designed into a structure having separate parts, comprising a cylindrical body 22 having an opening on each end and a second lid 21. As shown in FIGS. 1 and 2, the second lid 21 has a cup-shaped structure comprising a bottom wall and a side wall. The second lid 21 is rotatably and sealingly connected with the cylindrical body 22 at a second opening end of the cylindrical body 22 so as to form the container body 2. The first lid 1 is rotatably and sealingly connected with the cylindrical body 22 at a first opening end of the cylindrical body 22. The rotatable and sealing structure between the second lid 21 and the cylindrical body 22 may be identical with or different from that of the first lid 1. The specific sealing manner is identical with the sealing manner of the first lid 1 and the container body 2 as mentioned above. The second pipe 8 is provided on the second lid 21 for communicating the first chamber 9 with the outside. The relative position of ports of the first pipe 7 and the second pipe 8 in communication with the outside may be variable along with relative rotation of the first lid and the second lid. In the present embodiment, the first pipe 7 and the second pipe 8 are each arranged in an L-shape. The L-shape has one portion thereof extending along an axis of the cylindrical body 22 and another portion thereof extending to the outside from the side wall of the first lid 1 or the second lid 2. In order to prevent the first pipe 7 and the second pipe 8 from interfering from one another, upon rotation of the first lid 1 and the second lid 21, the L-shaped portions of the first pipe 7 and the second pipe 8 may be spaced on an axial direction and a radial direction of the cylindrical body 22, so as to reduce the mutual interference of the two pipes. In the case where the first lid 1 and the second lid 21 are each connected threadedly with the cylindrical body 22 in the manner as shown in FIG. 1, rotation of the first lid 1 and/or the second lid 21 may cause a displacement of the first lid 1 and/or the second lid 21 in an axial direction of the cylindrical body 22 such that there is a minor change with the volume of the liquid storage container. In the case where it is required to make an accurate control over the volume of the liquid storage container, after the first lid 1 and/or the second lid 21 are/is rotated to a desired position, it needs to adjust the volume of the liquid storage portion by adjusting the volume adjusting portion so as to control accurately the volume of the liquid storage portion at a volume as desired.


Further, in one embodiment, ports 71 and 81 of the first pipe and the second pipe positioned inside the chamber are at the same level, in order to further improve the versatility of the liquid storage container and the convenience of the connection. For example, in FIG. 1, in an operating state, the cylindrical body 22 is positioned vertically, where the ports 71 and 81 are at substantially the same level, such that there is no need to distinguish which of the first pipe and the second pipe should serve as an inlet pipe and which thereof should serve as an outlet pipe, which may facilitate pipeline connection of the entire system. Even if rotation of the first lid 1 and the second lid 21 may cause a minor change to the height of the ports 71 and 81, effect of such a change is negligible. Productivity is greatly increased as inlet and outlet pipes may not be distinguished. Further, in the operating state, it is not limited to that the liquid storage container is positioned vertically. When the liquid storage container is positioned horizontally or positioned otherwise, shapes and positions of the first pipe 7 and the second pipe 8 may be adjusted correspondingly, such that the ports are at substantially the same level so as to produce the same effect.


Besides, in one embodiment, in order to prevent the second chamber 10 from exhibiting an overly high pressure or an overly low pressure so to affect the adjustment of the first chamber 9 when a volume adjustment is made to the first chamber 9, the second chamber 10 may be provided with a pressure regulating means such as a pressure regulating valve or a small hole may be provided in the second chamber 10, so as to adjust timely a pressure of the second chamber when the second chamber 10 exhibits on an overly low or high pressure, such that the volume of the first chamber 9 may be adjusted successively.


Besides, it needs to be noted that name and position arrangement for the first lid, the second lid, the first chamber, the second chamber, the first pipe, the second pipe and the volume adjusting portion is not limited to that as shown in FIG. 1. Position of the first lid relative to the second lid, position of the first chamber relative to the second chamber and position of the first pipe relative to the second pipe each may be adjusted, so far as it can produce the technical effect of the present application.
