Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to specific embodiments of the present invention and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The following describes in detail the technical solutions provided by the embodiments of the present invention with reference to the accompanying drawings.

An embodiment of the invention discloses an integrated closestool key structure, which comprises a button assembly and a driving assembly.

Specifically, as shown in fig. 1 and fig. 4 to 7, the button assembly includes a button rod 1 and a pressing rod 2, the pressing rod 2 is located below the button rod 1, the pressing rod 2 is used for pressing a drainage valve key 3 of the toilet, that is, when the integrated toilet key structure is assembled in the toilet tank, the pressing rod 2 is suspended above the drainage valve key 3 of the toilet, or the lower end of the pressing rod 2 is abutted with the drainage valve key 3 of the toilet. Like this, when pressing button pole 1, button pole 1 can drive depression bar 2 and push down the removal, extrudees drain valve button 3, makes the drain valve of closestool open, realizes manual bath. When the push button bar 1 is not pressed, the push button bar 2 is driven to move upwards by the return of the drain valve key 3, so that the push button bar 2 is reset to the initial position (namely, the position where the push button bar 2 is located in fig. 4).

Of course, the button assembly may further include an elastic member 20, where the elastic member 20 is configured to provide a restoring force to the pressing rod 2 after the pressing movement, and when the button rod 1 is not pressed, the elastic member 20 drives the pressing rod 2 to move upwards to restore to the initial position.

As shown in fig. 3, 5, 6 and 9 to 11, the driving assembly comprises a driving block 4 and a driving source, the driving source can drive the driving block 4 to move along the horizontal direction, a driving inclined surface 6 is arranged on the driving block 4, a pressing rod inclined surface 7 matched with the driving inclined surface 6 is arranged on the pressing rod 2, and the pressing rod inclined surface 7 is positioned below the driving inclined surface 6; when the driving source does not work, the driving inclined plane 6 on the driving block 4 is far away from or lightly attached to the pressing rod inclined plane 7, and no force is generated between the driving inclined plane 6 and the pressing rod inclined plane 7; like this, when pressing button pole 1 drive depression bar 2 and pushing down the removal, drive inclined plane 6 and depression bar inclined plane 7 each other do not influence, and drive inclined plane 6 does not influence depression bar 2 and pushes down the removal promptly, and then makes the realization of the manual flushing function of electric drive subassembly not influencing the button structure. When the driving source works, the driving block 4 is driven to move along the horizontal direction, the driving inclined plane 6 is made to approach and squeeze the pressure lever inclined plane 7, a force is generated between the driving inclined plane 6 and the pressure lever inclined plane 7, and a component force in the vertical direction is generated due to the inclined plane, so that the pressure lever inclined plane 7 is driven to move downwards, the lower pressure lever 2 is driven to move downwards, the drainage valve key 3 is extruded, the drainage valve of the toilet is opened, and automatic flushing is realized. When the driving source drives the driving block 4 to move along the horizontal direction again, so that the driving inclined plane 6 is far away from the pressing rod inclined plane 7, namely no force is generated between the driving inclined plane 6 and the pressing rod inclined plane 7, the lower pressing rod 2 is reset to the initial position under the reset action of the drainage valve key 3.

In addition, the driving source can be controlled to work through the remote control key to realize automatic flushing; or the driving source is controlled to work through the sensing device, for example, when an infrared sensor on the closestool senses that a human body leaves the closestool, the driving source is controlled to work so as to automatically flush water; or the driving source is controlled to work by a remote control key and a sensing device.

In summary, in the integrated toilet key structure of the embodiment, by setting a pressing rod for pressing down a drain valve key of the toilet and setting a button rod above the pressing rod, when the button rod is pressed, the button rod can drive the pressing rod to press down the drain valve key, so as to realize manual flushing of the key structure; in addition, by arranging a driving source, a driving block with a driving inclined plane and a pressing rod inclined plane matched with the driving inclined plane on the pressing rod, when the driving source drives the driving block to move along the horizontal direction, the driving inclined plane can provide pressing force for the pressing rod inclined plane to drive the pressing rod to press a drainage valve key, so that automatic flushing of a key structure is realized; the integrated closestool key structure realizes the integrated design of manual flushing and automatic flushing, has simpler and more compact structure, is convenient to detach and maintain, has low production cost, and does not interfere with the manual flushing and the automatic flushing; in addition, because the integrated closestool button structure can be fixed on the water tank cover of closestool, make the driving source keep away from the work water line of water tank, can effectively prevent the emergence of the failure condition of intaking, this integrated closestool button structure can directly be applied to in the current closestool structure simultaneously, only need through changing the water tank lid can realize, and the installation is more convenient, need not to carry out extra design to the closestool structure, also need not to change the drain valve, has further reduced the manufacturing cost of closestool.
