Abstract
Description
Technical Field
[0001] The utility model relates to an overflow structure of a toilet flushing system, in particular to an overflow structure of a pure flat toilet flushing system. Background Art
[0002] The overflow structure of the flushing system of the existing flat toilet with a water tank adopts different overflow structures according to the different ways of setting the water tank. When the ceramic body comes with a ceramic water tank, that is, the water tank and the ceramic body are integrated, a concave structure is usually made locally at the connection between the ceramic body and the ceramic water tank for overflow, and the water in the water tank is not introduced into the toilet pot surface through the concave structure. When the ceramic body is embedded in a plastic water tank, that is, a plastic water tank is installed separately in the ceramic body, a concave structure is usually made locally in the ceramic body, and an overflow channel is made on the side of the plastic water tank and directly placed on the concave structure of the ceramic body, so that the water in the water tank is directly introduced into the toilet pot surface through the overflow channel. However, there is a common problem in both of the above overflow structures, that is, when the toilet sewage outlet is blocked, the sewage in the pot surface will flow back into the water tank through the overflow structure, causing the entire water tank to be polluted and smelly, and it is not easy to clean, which will affect the user experience and toilet environment for a long time. Utility Model Content
[0003] The utility model provides an overflow structure of a toilet flushing system to prevent the sewage on the toilet bowl from overflowing into the water tank, which overcomes the shortcomings of the background technology. The technical solution adopted by the utility model to solve the technical problem is:
[0004] A toilet flushing system overflow structure, the front part of the upper surface of the toilet ceramic body is concave to form a pot surface, the rear part of the upper surface of the toilet ceramic body is concave to form an installation chamber, the edge of the movement cover base is mounted on the top edge of the installation chamber, and a water tank is placed in the installation chamber. The water tank and the movement cover base are integrally formed or the water tank is separately arranged, and an overflow port is provided on the upper edge of the side wall of the water tank. A water trough is provided in the middle part of the upper surface of the toilet ceramic body, and the water trough connects the pot surface and the installation chamber. A sunken guide channel is provided on the movement cover base, one end of the guide channel is connected to the overflow port, and the other end is mounted above the water trough. Water overflowing from the overflow port can flow into the pot surface through the guide channel, and water overflowing from the pot surface can flow into the installation chamber through the water trough, and the installation chamber is provided with a drain port.
[0005] In a preferred embodiment: the water tank is separately arranged from the movement cover base, the movement cover base is provided with a clearance hole corresponding to the water tank, the side wall of the water tank is higher than the movement cover base, and the overflow port is set above one end of the diversion channel.
[0006] In a preferred embodiment: The water tank is located at the side of the base of the movement cover plate. The diversion channel includes a horizontal part and a vertical part. The vertical part of the diversion channel is erected above the water overflow tank and provides an installation space for the telescopic cleaner.
[0007] In a preferred embodiment: The depth of the horizontal part of the diversion channel is greater than that of the vertical part.
[0008] In a preferred embodiment: The drain port is arranged on the bottom wall of the installation chamber.
[0009] Compared with the background technology, this technical solution has the following advantages:
[0010] 1. When the water inlet valve fails to stop the water flow, the water overflowing from the water tank can flow into the pot surface of the ceramic body through the diversion channel. If the ceramic body is also blocked, when the water level in the pot surface rises to the water overflow tank, the water can flow into the installation chamber through the water overflow tank and finally overflow to the floor through the drain port. Since the diversion channel is higher than the water overflow tank, the water on the pot surface will not flow back into the water tank through the diversion channel. Therefore, in this application, the water overflow tank is used as the overflow channel for the water overflowing from the pot surface, effectively preventing the sewage on the toilet pot surface from overflowing into the water tank.
[0011] 2. The water tank is set separately, which simplifies the structure of the base of the movement cover plate. Moreover, the overflow port is arranged above the water inlet end of the diversion channel, and all the water overflowing from the water tank can enter the diversion channel, and the structure is simple.
[0012] 3. The vertical part of the diversion channel can provide an installation space for the telescopic cleaner, that is, the vertical part of the diversion channel shares the position originally used for installing the telescopic cleaner on the base of the movement cover plate. In this way, the modification to the base of the movement cover plate is small, and the large depth of the horizontal part of the diversion channel is convenient for the installation and positioning operation of the telescopic cleaner.
