Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific examples, but the present invention is not limited to these examples.
The example relates to a novel automatic toilet flushing device, as shown in figure 1, and the novel automatic toilet flushing device is a schematic view seen from one side. The automatic toilet flushing device mainly comprises a toilet body 1, a waterway pipeline and a toilet door body 3. The toilet body 1 is of a common plate-type partition structure. The waterway pipeline comprises a water outlet pipe 2, an automatic flushing valve 7, a flushing valve core 9, a lower ratchet wheel 6 and a water supply pipe 8. The toilet door body 3 includes a door panel, a door handle 5, an upper ratchet 4, an upper ratchet follower pin 10 and an upper ratchet hold-down spring 11.
As shown in fig. 2, 3, 4 and 5, the water supply pipe 8 of the waterway pipeline is fixed on the toilet body 1, and the upper end of the waterway pipeline is connected with the automatic flushing valve 7, and the lower end of the waterway pipeline is connected with the toilet or the toilet pit. The automatic flushing valve 7 is fixedly arranged at the rotating shaft center of the toilet door body 3; the water outlet pipe 2 is arranged below the automatic flushing valve 7. The flushing valve core 9 is a rotary valve core of the automatic flushing valve 7, and the opening and closing of the waterway are realized through rotation. One end of the flushing valve core return spring 13 is fixed on the flushing valve core 9, and the other end is fixed on the outer side of the automatic flushing valve 7. The upper end of the flushing valve core 9 is provided with a lower ratchet 6; the whole lower ratchet 6 is cylindrical, and ratchets are distributed on the upper surface along the circumference. The long side edge of the toilet door body 3 is arranged on the toilet body 1 and can be opened and closed in a rotating mode. The upper ratchet wheel 4 is arranged above the lower ratchet wheel 6, the upper ratchet wheel 4 is integrally cylindrical, the diameter of the outer side of the upper ratchet wheel is the same as that of the lower ratchet wheel 6, and ratchets are distributed on the lower surface of the upper ratchet wheel 4 along the circumference. The ratchet teeth of the upper ratchet wheel 4 and the lower ratchet wheel 6 are mutually meshed. A counter bore 12 is arranged in the middle of the upper ratchet 4; the lower end of the counter sink 12 is round, and the upper end is rectangular. The section of the upper ratchet wheel follow-up pin 10 is rectangular, and the upper ratchet wheel follow-up pin is arranged in a counter bore 12 of the upper ratchet wheel 4 and is in clearance fit with the counter bore. The cross section of the upper end of the flushing valve core 9 is rectangular, and a rectangular hole channel is arranged in the middle of the lower ratchet wheel 6 and is in clearance fit with the rectangular section of the flushing valve core 9. The lower end of the upper ratchet follower pin 10 is large. The upper ratchet wheel follow-up pin 10 is fixedly arranged on the toilet door body 3 and rotates along with the opening and closing of the toilet door body 3. The length of the upper ratchet wheel follow-up pin 10 is greater than that of the upper ratchet wheel 4, and an upper ratchet wheel pressing spring 11 is sleeved at the upper end of the upper ratchet wheel follow-up pin 10; the lower end of the upper ratchet wheel pressing spring 11 is pressed on the upper surface of the upper ratchet wheel 4, and the upper end of the upper ratchet wheel pressing spring is pressed on the toilet door body 3; the outside of the toilet door body 3 is also provided with a door handle 5.
As shown in fig. 4 and 5, the axes of the automatic flush valve 7, the flush valve core 9, the lower ratchet 6, the upper ratchet 4 and the upper ratchet pressing spring 11 are overlapped, and are overlapped with the rotation axis of the toilet door 3. The rotation axes of the flushing valve core 9 and the upper ratchet wheel follow-up pin 10 are also coincided with the rotation axis of the toilet door body 3. The ratchet teeth on the upper surface of the lower ratchet wheel 6 are the same as the ratchet teeth on the lower surface of the upper ratchet wheel 4 and can be meshed with each other.
Therefore, when the user opens the door, the toilet door 3 is rotated by pulling the door handle 5. When the toilet door body 3 rotates, the upper ratchet wheel follower pin 10 fixedly connected with the toilet door body can be driven to rotate around the rotating axis of the toilet door body 3. Meanwhile, the sections of the upper ratchet wheel follow-up pin 10 and the upper end of the counter bore 12 in the upper ratchet wheel 4 are rectangular, so that the upper ratchet wheel follow-up pin 10 rotates and drives the upper ratchet wheel 4 to rotate around the rotating axis of the toilet door body 3. In addition, due to the pressing action of the upper ratchet pressing spring 11, the ratchets of the upper ratchet 4 and the ratchets of the lower ratchet 6 are meshed with each other, so that the lower ratchet 6 rotates around the rotating shaft center of the toilet door body 3 along with the upper ratchet 4. And when the lower ratchet wheel 6 rotates, the flushing valve core 9 is driven to rotate around the rotating axis of the toilet door body 3, so that the automatic flushing valve 7 is opened, the water outlet pipe 2 is communicated with the water supply pipe 8, and toilet flushing is realized.
When the door is closed, although the upper ratchet wheel pressing spring 11 enables the ratchets of the upper ratchet wheel 4 and the ratchets of the lower ratchet wheel 6 to be meshed with each other, the toilet door body 3 drives the upper ratchet wheel follow-up pin 10 and the upper ratchet wheel 4 to rotate along opposite directions, the ratchets cannot actively transmit power along the direction of the long inclined plane with the smaller inclination angle, and after the flushing valve core return spring 13 pulls the flushing valve core 9 and the lower ratchet wheel 6 back to the closed position, the rotation of the upper ratchet wheel 4 cannot continue to drive the lower ratchet wheel 6 to excessively rotate. Thereby the flushing valve core 9 is not driven when the door is closed, and the toilet flushing is not carried out. Finally, the toilet flushing is carried out during the door opening period when the toilet is in use or is out of use before the use, and the cleanness and the sanitation of the toilet are ensured during the use.
In conclusion, through the components such as the upper ratchet wheel 4, the door handle 5, the lower ratchet wheel 6, the automatic flushing valve 7, the water supply pipe 8, the flushing valve core 9, the upper ratchet wheel follow-up pin 10, the upper ratchet wheel compression spring 11 and the like, the functions of automatically flushing the toilet, guaranteeing the practical sanitation and timely flushing after use are realized, meanwhile, the water is saved, and the phenomenon that the toilet is not flushed due to user quality or neglect of the water is solved. Therefore, the utility model has the advantages of extremely simple structure, extremely low cost, convenient installation and maintenance and easy improvement and acquisition on the basis of the prior toilet.
