Here, the tank 10 is shown in this embodiment to be filled with salt, so that the tank 10 is also called a salt tank of an existing water softener.

As shown in fig. 3, the top cover device of the embodiment of the present invention includes a middle frame assembly 20, a first top cover assembly 30, and a second top cover assembly 40.

Wherein, center subassembly 20 is connected with the case mouth 12 of box 10 is detachable, is equipped with first mouth 24 on the center subassembly 20, and first mouth 24 is as the salt mouth that adds of water softener, first mouth 24 with hold the chamber 11 intercommunication.

To facilitate the salting operation, the present embodiment pivotally connects one end of the first cover assembly 30 to the center frame assembly 20. In this case, the first cover member 30 may also be referred to as a flip member, and the first cover member 30 is controlled to be flipped with respect to the middle frame member 20 to conveniently control the closing or opening of the first through-opening 24 based on the first cover member 30.

As shown in fig. 3, the first cover assembly 30 of the embodiment of the present invention includes a cover 31 and a crank arm 32, wherein a first end of the crank arm 32 is connected to one end of the cover 31, and a second end of the crank arm 32 is rotatably connected to the middle frame assembly 20.

In the present embodiment, the middle frame assembly 20 is provided with an adapter 34, and the second end of the crank arm 32 is rotatably connected to the adapter 34. In order to ensure the aesthetic property of the crank arm 32, a decoration piece 36 is arranged on the side surface of the crank arm 32, and the crank arm 32 and the decoration piece 36 are detachably connected through a clamping structure.

In order to avoid the interference between the movement of the crank arm 32 and the middle frame assembly 20, the present embodiment provides an avoiding opening 27 on the middle frame assembly 20, at least a portion of the crank arm 32 is located in the avoiding opening 27, and the adapter 34 is disposed on one side of the avoiding opening 27.

Here, the present embodiment is based on the arrangement of the crank arm 32, and can enable the cover 31 to be turned over relative to the middle frame assembly 20 between the first position for closing the first through opening 24 and the second position for opening the first through opening 24, and ensure that the cover 31 can reach a relatively large turning angle relative to the middle frame assembly 20.

Further, the present embodiment can optimize the structure of the crank arm 32 so that the turning angle of the cover 31 relative to the middle frame assembly 20 is greater than 90 °, so that the upper side of the first through opening 24 can reach a sufficiently large open space in the case that the cover 31 is in the second position, thereby facilitating the operator to add salt into the box 10 through the first through opening 24.

As shown in fig. 2 and 8, in order to ensure that the turning angle of the cover 31 relative to the middle frame assembly 20 is greater than 90 °, the crank arm 32 shown in this embodiment includes a long arm section 321 and a short arm section 322.

The long arm section 321 is arc-shaped, and the short arm section 322 is linear; the first end of the long arm 321 is connected to one end of the cover 31, the second end of the long arm 321 is connected to the first end of the short arm 322, and the second end of the short arm 322 is rotatably connected to the adapter 34 of the middle frame assembly 20.

Wherein, the distance between the second end of the short arm section 322 and the first end of the long arm section 321 is smaller than the distance between the first end of the short arm section 322 and the first end of the long arm section 321, so that the curved arm 32 shown in the present embodiment is similar to a fishhook shape.

Here, the present embodiment is based on the optimized design of the crank arm 32, which not only ensures that the cover 31 can reach a relatively large turning angle relative to the middle frame assembly 20, but also ensures that the cover 31 is far away from the first through opening 24 as far as possible when reaching the maximum turning angle, thereby improving the convenience of the salting operation.

As shown in fig. 4 and 8, the first cover assembly 30 of the present embodiment is further provided with a stop portion 35, the stop portion 35 is connected to the crank arm 32, and the stop portion 35 is used for abutting against or separating from the middle frame assembly 20.

Specifically, in the present embodiment, the abutting portion 26 is provided on the middle frame assembly 20. When the lid 31 is in the first position, the stopper portion 35 is separated from the abutting portion 26, and when the lid 31 is in the second position, the stopper portion 35 abuts against the abutting portion 26.

Here, the second position of the cover 31 shown in this embodiment corresponds to the position of the cover 31 when the cover reaches the maximum flip angle with respect to the middle frame assembly 20. For example, the cover 31 may be rotated at a maximum angle of 100 ° to 150 ° with respect to the middle frame assembly 20.

Because when the cover 31 is in the second position, the cover 31 is inclined relative to the vertical plane, and the stop portion 35 and the abutting portion 26 abut against each other, the cover 31 can be ensured to be in a stress balance state, and under the condition that the manual support of an operator is not needed, the cover 31 can be stably maintained in the second position, the state of the cover will not change, and only when the first through opening 24 needs to be closed, the cover 31 is driven by the operator to be overturned from the second position to the first position.

In practical applications, the first connection line corresponding to the first plug-in terminal 1001 penetrates through the first bayonet 2311, and the first bayonet 2311 is clamped at the second end of the first plug-in terminal 1001; a second connecting wire corresponding to the second plug terminal 1002 penetrates through the second bayonet 2312, and the second bayonet 2312 is clamped at the second end of the second plug terminal 1002.

In some examples, the present embodiment may provide that the width of the first bayonet 2311 is smaller than the maximum diameter of the second end of the first plug terminal 1001, and the width of the second bayonet 2312 is smaller than the maximum diameter of the second end of the second plug terminal 1002.

Thus, when the first plug terminal 1001 is pulled by a power adapter, the first plug terminal 1001 does not pass through the first bayonet 2311 under the action of the pulling force, but the first bayonet 2311 limits the first plug terminal 1001 to move towards a side away from the second plug terminal 1002, so as to achieve the effect of preventing the plug assembly 100 from being separated under the action of an external force.

Accordingly, when an operator carelessly applies a pulling force to the connection line of the second jack terminal 1002, the second jack terminal 1002 does not pass through the second bayonet 2312 under a pulling force, but the second bayonet 2312 restricts the second jack terminal 1002 from moving toward a side away from the first jack terminal 1001, thereby achieving an effect of preventing the plug assembly 100 from being separated under an external force.
