When the user finishes pouring water, if the dust cover 2 needs to be closed, the locking of the protruding portion 413 and the stop groove 132 needs to be released, the user can press the key 42 downwards again, the rotor driving piece 41 can slide downwards along with the protruding portion 413 can be separated from the stop groove 132 under the driving of the key 42 and slide into the other limit groove 131 communicated with the stop groove 132, at this time, the limit protruding portion 411 can be separated from the abutting plane 31, the push rod 33 is reset, and the dust cover 2 is reset to the closed state due to the loss of support.

More specifically, as shown in fig. 12 and 13, the key 42 has a pushing tooth 422, the protrusion 413 has a third guide surface 413a, and external teeth of the pushing tooth 422 are used to be in abutting engagement with the third guide surface 413a to push the protrusion 413 to slide along the limit groove 131, thereby achieving synchronous movement of the rotor driver 41 and the key 42. When the pushing teeth 422 push the protruding portion 413 to slide to a position where the bottom of the limiting groove 131 communicates with the stop groove 132, the inclined surfaces of the pushing teeth 422 can cooperate with the third guide surface 413a to push the rotor driving piece 41 to rotate around the axial direction of the mounting hole 13, so that the protruding portion 413 is along the stop groove 132.

Similarly, when the protrusion 413 is clamped to the stop slot 132, the user presses the button 42 downwards again, the pushing teeth 422 push the protrusion 413 to slide downwards along the stop slot 132, and when the protrusion 413 slides to a position where the stop slot 132 is communicated with the adjacent other stop slot 131, the rotor driving member 41 can rotate around the axial direction of the mounting hole 13 again under the cooperation of the third guiding surface 413a and the inner wall of the mounting hole 13, so that the protrusion 413 can slide from the stop slot 132 into the adjacent other stop slot 131.

Note that, when the key 42 is pressed for the first time or when the key 42 is pressed again, the key 42 and the rotor driver 41 always move together by pushing the middle portion (as shown in fig. 12 and 13) of the third guide surface 413a through the external teeth of the pushing teeth 422, and the rotor driver 41 always rotates in the same direction.

In a specific embodiment, as shown in fig. 2 and 3, the switch assembly 4 further includes a switch return spring 43, and a spring mounting groove 111 is provided in the accommodating cavity 11, and one end of the switch return spring 43 abuts against the rotor driving member 41, and the other end abuts against a bottom wall of the spring mounting groove 111.

The rotor driving member 41 moves toward the bottom wall of the spring mounting groove 111 under the driving of the key 42, during which the switch return spring 43 is compressed, and during the sliding of the boss 413 along the stopper groove 132, the switch return spring 43 is also always in a compressed state; the user presses the key 42 downward again, and causes the protrusion 413 to be separated from the stop groove 132 by the driving of the key 42, and to slide into the other stop groove 131 in communication with the stop groove 132, the user has stopped pressing the key 42, at this time, the force applied to the switch return spring 43 is removed, and the switch return spring 43 can drive the rotor driving member 41 to move upward and under the action of its own return force, so that the rotor driving member 41 and the key 42 complete the reset.

As shown in fig. 2 and 3, the container cover further includes a water sealing valve assembly 7, the water sealing valve assembly 7 includes a valve body 71 and a sealing ring 72, one end of the valve body 71 is fixedly connected with the rotor driving member 41, and the other end is fixedly connected with the sealing ring 72. The lower cover 103 is provided with a water through hole 103b, as shown in fig. 3, when the rotor driving member 41 is pressed to move downwards, the valve body 71 moves downwards synchronously with the rotor driving member, so that the sealing ring 72 can be away from the water through hole 103b, and the water through hole 103b is opened, and at the moment, liquid can flow to the spout 103a; as shown in fig. 2, when the rotor driving member 41 is reset, the valve body 71 is driven to move upwards synchronously, so that the sealing ring 72 can close the water through hole 103b, and at this time, the liquid cannot flow to the spout 103a.

In summary, the specific working process of the container cover is as follows: when the user needs to pour water, the button 42 needs to be pressed down first, so that the pushing teeth 422 of the button 42 can push the protruding portion 413 of the rotor driving member 41 downward, so as to drive the rotor driving member 41 to move downward along the limiting groove 131 together (in this process, the first guiding surface 412 of the rotor driving member 41 can be matched with the guiding matching surface 32 of the pushing member 3, so that the pushing member 3 slides in the accommodating cavity 11 along the direction approaching to the dust cover 2, and the dust cover 2 rotates around the rotating shaft 5 by pushing the rotating arm 21 by the push rod 33), the pushing teeth 422 can be matched with the third guiding surface 413a, and the rotor driving member 41 is pushed to rotate around the axial direction of the mounting hole 13, so that the protruding portion 413 can slide into the stop groove 132 along the limiting groove 131. At this time, the user may stop pressing the key 42, the switch return spring 43 may drive the rotor driving member 41 to move upward under the action of the own restoring force, since the stop groove 132 may play a limiting role on the protrusion 413, the protrusion 413 may slide only in the stop groove 132 to be clamped with the triangular structure of the stop groove 132, in this process, the key 42 may also move upward under the action of the restoring force of the switch return spring 43, and when the protrusion 413 is clamped and fixed with the stop groove 132, the limiting protrusion 411 may abut against the abutment plane 31, so that the dust cover 2 may maintain the open state (in the above process, the relative positional relationship between the pushing teeth 422 and the protrusion 413 is changed from the state shown in fig. 12 to the state shown in fig. 13). And in the whole process, the water sealing valve assembly 7 always moves synchronously with the rotor driving piece 41, so when the dust cover 2 is kept in an open state, the sealing ring 72 can open the water through hole 103b, and liquid can smoothly flow out of the container body through the kettle mouth 103a.

When the user finishes pouring water, the button 42 can be pressed downwards again, so that the pushing teeth 422 push the protruding part 413 downwards again and compress the switch return spring 43, and when the protruding part 413 slides to a position where the stop groove 132 is communicated with the adjacent other limit groove 131, the pushing teeth 422 can be matched with the third guide surface 413a again to push the rotor driving piece 41 to rotate around the axial direction of the mounting hole 13, and therefore the protruding part 413 can be separated from the stop groove 132 and slide into the adjacent other limit groove 131. At this time, the user can stop pressing the key 42 again, and under the action of the restoring force of the switch restoring spring 43, the protruding portion 413 can slide upward along the limiting groove 131, so as to realize the restoration of the rotor driving member 41 and the key 42 (in this process, the limiting protrusion 411 is gradually far away from the abutment plane 31, the pushing member 3 can restore under the action of the restoring force of the pushing restoring spring 6), and the dust cover 2 which is not supported can also rotate under the action of gravity to restore to the closed state shown in fig. 2. In all the above processes, the water sealing valve assembly 7 moves synchronously with the rotor driving member 41 all the time, and when the dust cover 2 rotates to the closed state, the sealing ring 72 can close the water through hole 103b, so as to prevent liquid from flowing to the spout 103a.

The present application also provides a liquid heating vessel comprising a vessel body and a vessel cover as described in any of the embodiments above. When a user uses the liquid to heat the container to pour water, the dustproof cover 2 can be opened by pressing the key 42, then the container body is poured, so that the liquid in the container body flows out through the spout 103a, after the use is finished, the dustproof cover 2 is closed by pressing the key 42, and the user does not need to keep the posture of pressing the key 42 all the time when using, so that the use feeling of the user is improved. And the dust cap 2 can be stably kept in an open state in the pouring process, so that the spout 103a can be ensured to smoothly discharge water.

The foregoing is merely a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and variations may be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
