In order to facilitate the opening of the dust cap 10, the dust cap 10 is elastically and rotatably disposed on the container cover body 70, and the dust cap 10 is rotatably disposed on the container cover body 70 through a shaft, as an embodiment, a torsion spring is sleeved on the shaft, one end of the torsion spring abuts against the upper end surface of the mounting groove 701, and the other end abuts against the inner side of the dust cap 10; as another embodiment, an elastic ring 50 is inserted into the shaft at one end and inserted into the hook groove at the rotating end of the shaft inside the dust cap 10 at the other end. When the dust cap 10 is opened, the dust cap 10 can be rapidly opened by the torsion spring or the elastic ring 50, and it is ensured that the dust cap 10 is not accidentally closed in the opened state.
In order to prevent the dust cap 10 from being accidentally opened when the dust cap 10 is closed on the container cover body 70, the dust cap 10 and the push button 40 are locked by a locking mechanism. In the prior art, the locking mechanism is a well-established technique, and the present invention is not limited thereto. In the present embodiment, the dust cap 10 is engaged with the push button 40 in the closed state of the dust cap 10. For example, the push button 40 is provided with a buckle 406, the dust cap 10 is provided with a slot, and when the dust cap 10 is covered, the buckle 406 is clamped with the slot. When the suction nozzle 30 is opened from the closed state, the push button 40 is pushed, the catch 406 is separated from the catch, and the dust cap 10 is opened under the elastic action of the torsion spring or the elastic ring 50.
In the present embodiment, the suction nozzle 30 is in a closed state, in which it is in toothed engagement with the push button 40.
When the suction nozzle 30 is opened from the closed state, only the pushing portion 401 of the push button 40 needs to be pressed, the push button 40 slides into the mounting groove 701, at this time, the dust cap 10 is pushed open by the push button 40, and the push button 40 drives the suction nozzle 30 to rotate in the opening direction through a transmission mode of gear engagement until the suction nozzle 30 is communicated with the water outlet 706.
When the suction nozzle 30 is closed from the open state, by closing the dust cap 10, the dust cap 10 pushes the push button 40 to move to the outside of the mounting groove 701 in the closing process, and the push button 40 drives the suction nozzle 30 to rotate in the closing direction until the suction nozzle base 302 is sealed on the water outlet 706.
Referring to fig. 19 to 21, in the present embodiment, a carrying buckle 60 is further disposed on the container cover body 70, and the carrying buckle 60 and the dust cover 10 are coaxially and rotatably disposed. Preferably, a connecting portion 705 is disposed on one side of the container cover body 70, the connecting portion 705 defines a shaft hole, and a rotating shaft 20 is inserted into and passes through the shaft hole, and the rotating shaft 20 rotates relative to the shaft hole. The ends of the carrying buckle 60 and the dust cover 10 are respectively fixed on the rotating shaft 20, that is, the carrying buckle 60 and the dust cover 10 move synchronously, and the carrying buckle 60 and the dust cover 10 are perpendicular to each other. When the dust cap 10 is closed, the carrying buckle 60 is erected for carrying.
Principle of installation of the invention
Referring to fig. 10 to 12, first, the push button 40 is installed in the installation groove 701 of the container cover body 70, and the push portion 401 is suspended outside the container cover body 70;
then, the suction nozzle 30 is installed in the installation groove 701 at an excessive opening angle (please refer to the inclination angle of the suction nozzle 30 shown in fig. 10 to 12), the shaft holes 304 of the cylinders 303 at both sides of the suction nozzle base 302 are sleeved on the two convex columns 702 in the installation groove 701, at this time, the gear teeth 305 on the cylinders 303 are not meshed with the rack 403 on the push button 40, and the suction nozzle base 302 is not sealed on the water outlet 706;
referring to fig. 13 to 15, the suction nozzle 30 is rotated to the closed state;
referring to fig. 16 to 18, the push button 40 is pushed into the mounting groove 701, so that the outer side surface of the pushing portion 401 is flush with the outer ring of the container cover body 70, at this time, the gear teeth 305 on the nozzle base 302 are engaged with the rack 403 on the push button 40, and the inner end of the push button 40 has a gap from the inner wall of the mounting groove 701. In order to ensure that the outer side surface of the pushing portion 401 is flush with the outer ring of the container cover body 70, the outer side surface of the pushing portion 401 is in conformity with the outer ring of the container cover body 70.
Finally, the dust cap 10 and the carrying buckle 60 are mounted on the container cover body 70, and the dust cap 10 is clamped with the push button 40, at this time, the dust cap 10 covers the suction nozzle 30.
When the suction nozzle 30 is opened from the closed state, first, the push button 40 is manually pushed into the container cover body 70, the dust cap 10 is pushed open by the push button 40, the push button 40 drives the suction nozzle 30 to rotate in the opening direction through a transmission manner of gear engagement until the suction nozzle 30 is communicated with the water outlet 706, referring to fig. 22, at this time, the push button 40 abuts against the inner wall of the mounting groove 701, and therefore, the push button 40 cannot be pushed into the container cover body 70 any more.
When the suction nozzle 30 is closed from the open state, the dust cap 10 is closed, the dust cap 10 pushes the push button 40 in the opposite direction (to the outer side of the container cover body) in the closing process, the push button 40 drives the suction nozzle 30 to rotate in the closing direction through a transmission mode of gear engagement until the suction nozzle base 302 is sealed on the water outlet 706, at this time, the outer side surface of the push portion 401 is flush with the outer ring of the container cover body 70, and the dust cap 10 is clamped with the push button 40, please refer to fig. 23.
