In another embodiment, under the condition that the sealing member 21 is in the avoiding position, the elastic positioning member 25 is in a free state, which means that the elastic positioning member 25 is in a natural unstressed state, and there is no acting force or reacting force between the elastic positioning member 25 and the connecting seat 23, in this case, if the sealing member 21 intends to recover from the avoiding position to the sealing position, the elastic positioning member 25 will deform to generate a resisting moment for obstructing the movement of the sealing member 21, and therefore, in the case that the driving rod 22 does not input a torque, the sealing member 21 will not automatically recover to the sealing position, that is, the sealing member 21 can be ensured to be reliably in the avoiding position.

In the embodiment of the present application, referring to fig. 7 and 8, the elastic positioning element 25 is a torsion spring 25 ', the torsion spring 25 ' includes a first leg 251 and a second leg 252, wherein the first leg 251 is connected to the cover 30, the second leg 252 is connected to a side of the connecting seat 23 away from the sealing element 21, the second leg 252 and the sealing element 21 are located at two opposite sides of the connecting seat 23 along the transverse direction of the rotation center line L1, the second leg 252, the connecting seat 23 and the sealing element 21 generally form a lever structure, and the sealing element 21 is reliably positioned at the sealing position and the avoiding position by the torsion spring 25 '.

Therefore, the installation is convenient, and the torsion spring 25' can move along with the connecting seat 23 to protect the first foot 251 and the second foot 252.

In the embodiment of the present application, the connecting seat 23 and the cover 30 squeeze the torsion spring 25 ' therebetween, specifically, referring to fig. 7, when the sealing member 21 is in the sealing position, the torsion spring 25 ' is in a first working state of being squeezed, at this time, the torsion spring 25 ' applies an acting force F1 to the connecting seat 23, and the acting force F1 forms a first moment W1 to the connecting seat 23; referring to fig. 8, when sealing member 21 is in the retracted position, torsion spring 25 'is in the second working state of being pressed, and at this time, torsion spring 25' applies a force F2 to connecting holder 23, and force F2 forms a second torque W2 to connecting holder 23. In this way, the seal 21 can be stably locked at the sealing position and the escape position by the torsion spring 25', and the seal device is highly reliable and simple in structure.

Specifically, referring to fig. 7 and 8 in combination, when the sealing member 21 rotates between the sealing position shown in fig. 7 and the avoiding position shown in fig. 8, since the first torque W1 of fig. 7 is clockwise, the second torque W2 of fig. 8 is counterclockwise, that is, a critical point exists at a certain intermediate position between the sealing position and the avoiding position, at which the torque applied to the connecting seat 23 by the torsion spring 25' is 0. Describing the case where the sealing member 21 is switched from the sealing position shown in fig. 7 to the avoiding position shown in fig. 8, when the driving link 22 inputs a torque rotating in the counterclockwise direction of fig. 7, so that the connecting seat 23 starts to rotate counterclockwise from the sealing position of fig. 7, the driving link 22 needs to continuously input the torque to overcome the clockwise torque of the torsion spring 25' to the connecting seat 23 before the connecting seat 23 crosses the critical point; when connecting seat 23 crosses the critical point, torsion spring 25 ' reverses the moment of connecting seat 23, i.e. applies a counterclockwise moment, and even if the torque of driving link 22 is cancelled, connecting seat 23 can rapidly rotate counterclockwise to the avoiding position under the action of torsion spring 25 ', and is locked at the avoiding position by torsion spring 25 '. The principle of switching the sealing member 21 from the escape position to the sealing position is the same as described above, and the direction is opposite to that described above, and thus, the description thereof is omitted.

Further, in the embodiment of the present application, torsion springs 25 'are disposed on two opposite sides of connecting seat 23 along rotation center line L1, and two torsion springs 25' cooperatively apply force to connecting seat 23, so that the positioning reliability of connecting seat 23 can be increased.

When the driving rod 22 drives the connecting seat 23 to rotate until the stopping portion 232 abuts against the supporting seat 24, at this time, the supporting seat 24 limits the further movement of the connecting seat 23, the elastic positioning element 25 acts on the connecting seat 23, and the first moment applied to the connecting seat 23 reliably abuts against one side of the supporting seat 24.

In one embodiment, the two opposite sides of the seat body 231 along the rotation center line L1 are provided with the stopping portions 232, and the two stopping portions 232 are stopped and positioned by the supporting seat 24, so as to improve the stress condition of the connecting seat 23.

Specifically, the shift lever assembly 50 and the driving rod 22 rotate together with the inner cylinder 11, when the partial structure of the shift lever assembly 50 extends toward the dial assembly 40, and the dial assembly 40 rotates to contact with the partial structure of the shift lever assembly 50, because the dial assembly 40 continues to rotate with the inner cylinder 11, the dial assembly 40 is forced by the blocking effect of the shift lever assembly 50 to drive the driving rod 22 to rotate around the rotation center line L1, the driving rod 22 drives the connecting seat 23 and the sealing member 21 to rotate, for example, so that the sealing member 21 is in the sealing position, and then the shift lever assembly 50 can be retracted, that is, the shift lever assembly 50 does not interfere with the rotation of the dial assembly 40, the torque of the driving rod 22 is cancelled, and the sealing member 21 is stably in the sealing position under the effect of the elastic positioning member 25. When drainage is required, the inner barrel 11 is reversed, part of the structure of the lever assembly 50 extends toward the dial assembly 40, the dial assembly 40 and the actuating rod 22 are reversed, the actuating rod 22 actuates the seal 21 to switch from the sealing position to the retracted position, and then the lever assembly 50 is retracted with the seal 21 in the retracted position.

In one embodiment, referring to fig. 1 and 4, the lever assembly 50 includes a lever 51 and a power unit 52 for driving the lever 51 to move, and the lever 51 can extend and retract toward the dial assembly 40 under the driving of the power unit 52. The movement of the shift lever 51 is not limited, and may be linear or rotary.

For example, in one embodiment, the lever assembly 50 is an electric push rod, and the lever 51 is a rod portion of the electric push rod. The rod part of the electric push rod moves linearly.

In another embodiment, the power unit 52 is a motor, and one end of the shift lever 51 is fixedly connected to a motor shaft of the motor, and the motor shaft can drive the shift lever 51 to rotate. For example, the motor shaft rotates in a forward direction, the shift lever 51 extends toward the dial assembly 40, the motor shaft rotates in a reverse direction, and the shift lever 51 retracts.

In one embodiment, referring to fig. 4 and 5, the dial assembly 40 includes a dial 41, a first dial 42, a second dial 43, a first position-limiting portion 44, a second position-limiting portion 45, and an elastic restoring member 26, the dial 41 is fixedly connected to the driving rod 22, a rotation center line L1 passes through the dial 41, and the dial 41 rotates around a rotation center line L1. It should be noted that the fixed connection refers to a connection mode without relative movement between the dial 41 and the driving rod 22, for example, the dial 41 and the driving rod 22 are integrally formed, or the driving rod 22 passes through the dial 41, and the driving rod 22 is engaged with the dial 41 or screwed. The first shifting piece 42 and the second shifting piece 43 are located on two opposite sides of a rotation center line L1 along the rotation circumference of the inner cylinder 11, the first shifting piece 42 is rotationally connected with the dial 41, the second shifting piece 43 is rotationally connected with the dial 41, the first limiting part 44 is located on one side of the first shifting piece 42 departing from the second shifting piece 43, the second limiting part 45 is located on one side of the second shifting piece 43 departing from the first shifting piece 42, the first shifting piece 42 is abutted against one side of the first limiting part 44 under the action of the elastic resetting piece 46, and the second shifting piece 43 is abutted against one side of the second limiting part 45 under the action of the elastic resetting piece 46.

The operation principle and operation of the dial assembly 40 will be described below. Referring to fig. 2, assuming that the inner barrel 11 rotates in the counterclockwise direction of fig. 2, the shift lever 51 extends toward the dial assembly 40, if the shift lever 51 is located outside the first dial 42, when the first dial 42 contacts the shift lever 51, the first dial 42 rotates counterclockwise, the shift lever 51 enters between the first dial 42 and the second dial 43, and the first dial 42 is reset by the elastic reset element 46; as the inner cylinder 11 drives the dial assembly 40 to rotate, the shift lever 51 abuts against the second dial 43, the second dial 43 cannot rotate freely under the action of the second limiting portion 45, the second dial 43 forces the dial 41 to rotate counterclockwise around the rotation center line L1, that is, at this time, the dial 41 revolves around the rotation axis L2 of the inner cylinder 11 and also rotates around the rotation center line L1, when the dial 41 rotates along with the inner cylinder 11 until the second dial 43 is separated from the shift lever 51, the shift lever 51 no longer shifts the second shift lever 43, and the second shift lever 43 no longer drives the dial 41 to rotate. It should be noted that, as long as the rotation angle of the dial 41 can make the connection seat 23 bypass the above-mentioned critical point, after the critical point is crossed, the connection seat 23 can continue to rotate under the action of the torsion spring 25' until the sealing member 21 moves to the avoiding position. Subsequently, the shift lever 51 is retracted. Or, the shift lever 51 is retracted after the inner cylinder 11 rotates for several circles, it can be understood that even if the shift lever 51 is not retracted, the first dial 42 will not block the shift lever 51, and the second dial 43 will not contact the shift lever 51, so that, in the subsequent rotation, the shift lever 51 will not affect the rotation of the inner cylinder 11, and the shift lever 51 will not block the inner cylinder 11. If the shift lever 51 is directly inserted into the first dial 42 and the second dial 43 when extended, the shift lever 51 does not need to bypass the first dial 42, and the rest of the principle and process are the same as above and will not be described herein again.

Further, the sealing member 21 is in a stationary state after being in the limit position (the avoidance position or the sealing position), and the sealing member 21, the driving rod 22 and the dial 41 are also in a stationary state simultaneously, and if the first dial 42 or the second dial 43 is not yet disengaged from the dial 51 in this case, the rotation of the inner cylinder 11 may be blocked, and the inner cylinder 11 may be jammed. For this reason, the relative positional relationship among the first dial 42, the second dial 43, and the shift lever 51 satisfies: during the process of switching the sealing member 21 from the escape position to the sealing position, the second toggle member 43 and the toggle lever 51 are disengaged from each other after the sealing member 21 passes the critical point and before the sealing position is reached or at the latest when the sealing member 21 reaches the sealing position; in the process of switching the seal 21 from the sealing position to the retracted position, the second driver 43 and the lever 51 are disengaged from each other after the seal 21 passes the critical point and before the seal 21 reaches the retracted position or at the latest while the seal 21 reaches the retracted position.

The drive plate assembly 40 of the embodiment of the application can prevent the inner barrel 11 from rotating by the drive rod 51 no matter where the inner barrel 11 rotates in the rotation process of the inner barrel 11, the inner barrel 11 can not be blocked, and when the position of the sealing element 21 needs to be switched, the inner barrel 11 does not need to be rotated to a specific position, and only the drive rod 51 needs to be extended.

The various embodiments/implementations provided herein may be combined with each other without contradiction.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
