Referring to fig. 1 to 5, specifically, a pressing rod is fixed on the top cover 2, and the pressing rod can rotate around a top cover rotating shaft 6 along with the top cover 2, but not limited thereto. For example, the pressing rod may be fixed to the top cover 2 by a fastener, or may be connected to the top cover 2 by a welding process, but not limited thereto. In the present embodiment, the strut includes a strut body 8 and a connecting rod 77 fixed to the strut body 8, as shown in fig. 2 to 4, which will be described in detail below.

In order to drive the top cover 2 to rotate around the top cover rotating shaft 6, the liquid container further comprises a cover opening elastic part 5, the cover opening elastic part 5 is connected between the container body 1 and the first end of the pressing rod, the cover opening elastic part 5 can provide a first torque for the pressing rod, and the top cover 2 is driven to rotate so that the top opening of the container body 1 is in an opening state.

The lid opening elastic member 5 is, for example, a lid opening torsion spring in the present embodiment, but not limited thereto. When the top cover 2 and the container body 1 are in a covering state in fig. 1, the cover opening elastic part 5 abuts against the first end (top end) of the pressing rod, the cover opening elastic part 5 provides counterclockwise torque for the pressing rod, the torque can be transmitted to the top cover 2, and when the latch 4 is separated from the latch groove, the top cover 2 rotates counterclockwise around the top cover rotating shaft 6 under the action of the first torque, so that the top opening is opened.

In order to improve the safety of the use process of the top cover 2 and avoid water splashing during the opening process of the top cover 2, the liquid container further comprises a damping component 7. In particular, the damping assembly 7 is connected between the second end of the strut and the top cover 2, the damping assembly 7 being capable of providing a second torque to the strut, the second torque being opposite to the first torque.

As an example, the damping assembly 7 is connected to the second end (bottom end) of the strut, and the damping assembly 7 is capable of providing a clockwise torque to the strut. At the 4 unblock initial stages of hasp, uncap elastic component 5 acts on the depression bar, makes the depression bar have around 6 anticlockwise rotations of top cap pivot, and under the drive of depression bar, top cap 2 will rotate around 6 anticlockwise rotations of top cap pivot to open for container body 1.

Along with the anticlockwise rotation of depression bar, second end (bottom) drive damping subassembly 7 of depression bar, drive subassembly 7 provides the second torque for the depression bar this moment, and this second torque is clockwise, so can avoid top cap 2 to wind 6 anticlockwise rotations of top cap pivot too fast, avoids top cap 2 to rotate the in-process and the phenomenon of getting rid of water appears to have improved top cap 2's safety in utilization.

With continued reference to fig. 1 to 4, in particular, the damping assembly 7 includes a damping seat 71 and a damping rod 72, the damping seat 71 is rotatably connected to the top cover 2, the damping rod 72 is slidably connected to the damping seat 71 along an extending direction of the damping seat 71, and a second end of the pressing rod is rotatably connected to a protruding end of the damping rod 72 exposed outside the damping seat 71.

As an example, the damping seat 71 is a cylinder with an opening at one end, the closed end of the damping seat 71 is rotatably connected to the top cover 2, the insertion end of the damping rod 72 is inserted into the inner cavity of the damping seat 71 through the opening end of the damping seat 71, and the damping rod 72 can slide in the damping seat 71, so that the elastic potential energy of the cover opening elastic part 5 is absorbed into the damping assembly 7 through the sliding of the damping rod 72 relative to the damping seat 71, thereby preventing the top cover 2 from turning over too fast to cause water throwing, and improving the use reliability of the top cover 2.

As an example, the damping assembly 7 may store energy by means of an elastic member, and specifically, the damping assembly 7 further includes a damping spring 74, and the damping spring 74 is compressively disposed between an insertion end of the damping rod 72 inserted into the damping seat 71 and the damping seat 71. During the sliding of the damping rod 72 with respect to the damping holder 71, for example, but not limited to, when the damping spring 74 is contracted, the elastic potential energy of the door opening elastic member 5 is stored in the damping spring 74, and when the damping spring 74 is extended, the elastic potential energy of the door opening elastic member 5 stored by the damping spring 74 is released. In this way, the relative sliding between the damping rod 72 and the damping seat 71 adjusts the rotation speed of the top cover 2, thereby avoiding water throwing caused by too high speed.

In order to meet various use requirements, the damping rod 72 comprises a rod body and a slide way 73, one end of the rod body is slidably arranged in the damping seat 71, the other end of the rod body is arranged outside the damping seat 71, namely an extending end, the slide way 73 is fixed at the other end of the rod body, the extending direction of the slide way 73 is parallel to the extending direction of the damping rod 72, the second end of the pressing rod is connected with a pressing rod slide block 76, and the pressing rod slide block 76 is slidably arranged in the slide way 73. Thus, in the process that the pressing rod sliding block 76 slides in the sliding way 73, the damping rod 72 does not receive the driving force of the pressing rod, namely, the damping rod 72 does not slide relative to the damping seat 71, the damping component 7 does not play a damping role in the process, the rotation of the top cover 2 is not inhibited by the damping component 7 in the process, so that the rotation of the top cover 2 is easier and faster, and the top cover 2 is easier to open.

By way of example, the pressing rod slider 76 moves from the first end to the second end of the slide way 73, and the top cover 2 rotates by an angle α, which satisfies 0 ° ≦ α ≦ 30 °, but not limited thereto, and the length of the slide way 73 may be selected according to actual needs. Optionally, the rotation angle α =15 ° of the top cover 2 is not limited thereto.

Referring to fig. 2 to 4, the pressing rod slider 76 in fig. 2 is located at a first end of the slide way 73, which may be a left end of the slide way 73, and the damping rod 72 is located at a left end of the damping base 71. The strut slider 76 in fig. 3 is located at the second end of the slide 73, which is the right end of the slide 73, and the damper rod 72 does not move relative to the damper base 71, as compared to fig. 2. At this time, when the plunger slider 76 is located at the second end of the slide 73, the rotation of the top lid 2 is stopped briefly, and then the top lid 2 continues to be opened slowly by the lid opening elastic member 5.

The plunger slide 76 from the position of fig. 3 will push the damper rod 72 to slide relative to the damper base 71, and the damper spring 74 is compressed to store energy. In the process, the damping rod 72 rotates with the damping base 71 about the damping rotation shaft 75, and the elastic potential energy of the lid opening elastic member 5 is stored in the damping assembly 7 during the process, so as to prevent the top lid 2 from rotating too fast and throwing water.

In fig. 4, the connecting rod 77 (described later) and the damper rod 72 are located on the same line. During the process of moving the damping assembly 7 from the state shown in fig. 3 to the state shown in fig. 4, the speed of the top cover 2 is reduced, and the condensed water on the top cover 2 is collected and flows down along the direction from the latch 4 to the top cover rotating shaft 6.

After the position in fig. 4, the top cover 2 continues to rotate, and at this time, the rotating speed of the top cover 2 is increased to the maximum extent that the top cover 2 is opened, and since the condensed water is collected and flows down, no condensed water exists on the top cover 2, and no potential safety hazard exists even when the rotating speed of the top cover 2 is increased.

As an example, the press rod is provided with a protrusion on which the end of the cover opening elastic member 5 may act in the present embodiment, thereby improving the reliability of the connection between the press rod and the cover opening elastic member 5, i.e., the protrusion is provided at the top end of the press rod, but not limited thereto.

Further, the pressure lever comprises a pressure lever body 8 and a connecting rod 77 fixed at the bottom end of the pressure lever body 8, one end of the connecting rod 77 is fixed on the pressure lever body 8, and the other end is connected with a pressure lever slider 76, for example, but not limited to, the pressure lever slider 76 is rotatably connected at the other end of the connecting rod 77. In addition, the compression bar body 8 and the connecting rod 77 may be formed in an integrated process, or may be separately formed and then fixedly connected together. The rotation of the top cover 2 in this embodiment goes through approximately three processes of fast-slow-fast.

In addition, the damping arrangement 7 can store energy by means of hydraulic oil. Specifically, the damping assembly 7 further includes a hydraulic pressure source (not shown) which is communicated with the damping seat 71 through a pipeline, and hydraulic oil can be filled in a space between the insertion end of the damping rod 72 inserted into the damping seat 71 and the damping seat 71. In this way, the damping rod 72 slides relative to the damping seat 71, and the elastic potential energy of the lid opening elastic member 5 is temporarily stored in the hydraulic oil, thereby preventing the water from being thrown due to an excessively high rotation speed of the top lid 2. The rotation of the top cover 2 in this embodiment goes through roughly two processes of fast-slow.
