In another exemplary embodiment, a mounting port (not shown) is further separately formed on the upper end side wall of the overflow communication channel 165, and the water replenishing pipe 166 is in sealing fit with the mounting port, so that the water replenishing pipe 166 is mounted on the overflow communication channel 165, and when the water level in the water tank 160 exceeds the overflow hole 167, the water directly overflows through the overflow hole 167.

Illustratively, the inside of the tub 120 is provided with an overflow water replenishing channel 122, the top of the overflow water replenishing channel 122 is communicated with the bottom of the overflow communicating channel 165, and the bottom of the overflow water replenishing channel 122 is communicated with the liquid outlet chamber 132. When the water tank 160 is filled with water through the water inlet valve 164, the water in the overflow communicating channel 165 flows into the outlet chamber 132 through the overflow water filling channel 122 and then flows into the water guiding ring 130 and the washing pipe 140. It is understood that, in the embodiment of the application, the bottom end of the overflow replenishing channel 122 may also directly communicate with the bottom of the water guide ring 130.

Since the lifespan of the toilet bowl 100 is long and the check valve 170 may be damaged due to frequent changes in the state during the long-term use of the toilet bowl 100, the check valve 170 may need to be separately replaced.

Referring to FIGS. 4-9, the example check valve 170 includes a valve body 1701 and a connection portion 1702, the valve body 1701 being configured to allow a unidirectional flow of water into the bowl 120; connecting portion 1702 is used for can dismantling with injection hole 111 and is connected, installs check valve 170 when making things convenient for production, changes check valve 170 as required when conveniently using simultaneously.

It is understood that, in the embodiment of the present application, the valve body 1701 allows water to flow unidirectionally into the bowl 120 in an unlimited manner, and the water discharge pipe 150 opens the water flow passage by sliding or rotating when supplying water to the spray chamber 110 to make water flow in a forward direction impact on the valve body 1701; the water discharge pipe 150 stops supplying water to the spray chamber 110 so that the positive impact of the water flow on the valve body 1701 disappears, and then it can keep the water flow passage closed by means of elastic force or gravity.

Referring to fig. 4, 5, 6, and 10, in some possible embodiments, a valve body 1701 includes a first housing 171, a first seal 172, and a return. The first housing 171 is connected to the connection portion 1702, and the first housing 171 has a first water inlet 1711 communicating with the injection hole 111. The first sealing member 172 has a first position for sealing the first water inlet 1711 and a second position for opening the first water inlet 1711, and the check valve 170 is in a first working state when the first sealing member 172 is in the first position, as shown in fig. 4; the check valve 170 is in a second operational state with the first seal 172 in the second position, as shown in FIG. 5. A return member is coupled between the first housing 171 and the first seal 172, the return member being configured to drive the first seal 172 in the first position and to allow the first seal 172 to move from the first position to the second position under the impact of the water stream flowing into the bowl 120. During flushing, the restoring force of the restoring member on the first sealing member 172 has a buffering effect on the movement of the first sealing member 172, so that the first sealing member 172 can be smoothly moved to the second position under the impact of the water flow; after the flushing is completed, the restoring force of the restoring member to the first sealing member 172 enables the first sealing member 172 to automatically restore from the first position, so that the opening and closing reliability of the check valve 170 is good.

It is understood that in the embodiment of the present application, the returning member is not limited to be disposed, and the returning member may be provided with an elastic expansion member 1732, such as an expansion spring; the return member may also be provided with a resilient torsion member, such as a torsion spring; the return member may also be provided with a resilient member made of a resilient material, such as a resilient post.

In a first class of embodiments, the return member is provided with a resilient telescoping member 1732 and slides the first seal 172 between the first and second positions.

Illustratively, the first housing 171 has a water flowing cavity therein communicating with the first water inlet 1711, and the first sealing member 172 is slidably disposed in the water flowing cavity of the first housing 171. The restoring member includes a guiding member 1731 and an elastic expansion member 1732, an axial direction of the guiding member 1731 is parallel to an axial direction of the first housing 171, a first end of the guiding member 1731 is connected with the first sealing member 172, a second end of the guiding member 1731 is slidably connected with the first housing 171, and the elastic expansion member 1732 is abutted between the first sealing member 172 and the first housing 171. Optionally, a mounting seat 1712 is disposed in the water flowing cavity of the first housing 171, the second end of the guiding member 1731 is slidably connected to the mounting seat 1712 along the axial direction of the first housing 171, and the elastic expansion member 1732 abuts between the sealing member and the mounting seat 1712.

In the above embodiment, the elastic expansion piece 1732 is provided as a restoring piece, and the first sealing member 172 can slide from the first position to the second position under the impact of the water flowing into the tub 120, and the first sealing member 172 can stably move between the first position and the second position due to the good stability of the elastic expansion piece 1732 in the expansion process and the good stability of the sliding movement mode. Since the pressure of the water flow in the toilet 100 is limited, the first sealing member 172 slides from the first position to the second position by compressing the elastic expansion member 1732 during flushing, the first sealing member 172 is easily washed away by the water flow in the spray chamber 110, and the valve body 1701 has a high sensitivity of opening the water flow path under the impact of the water flow flowing into the bowl 120. Meanwhile, since the toilet bowl 100 is frequently flushed during use, the elastic expansion member 1732 has a high impact deformation resistance, so that the valve body 1701 can have a long service life.

In an exemplary embodiment, valve body 1701 operates within injection chamber 110 through injection hole 111. The end of the first housing 171 remote from the connecting portion 1702 is located in the inner cavity of the injection chamber 110, the first water inlet 1711 is opened at an end face of the first housing 171 remote from the connecting portion 1702, and when the first sealing member 172 is located at the second position, a water flowing gap 1713 for water to flow through is formed between the first sealing member 172 and the first housing 171. The water flow gap 1713 reduces sliding friction of the first seal 172 with the first housing 171 as the first seal 172 moves between the first and second positions, making it easier for the water flow in the spray chamber 110 to blow open the first seal 172 and more sensitive for the valve body 1701 to open a water flow path under the impact of the water flow into the bowl 120.

Optionally, the first seal 172 is a first sealing barrier. An end face of the first housing 171, which is far away from the connecting portion 1702, has a flange inner edge, and the flange inner edge is arranged along the circumferential direction of the first housing 171 and encloses the first water inlet 1711. When the first sealing member 172 is located at the first position, the first sealing member 172 abuts against the inner edge of the flange and seals the first water inlet 1711. Exemplarily, one side of the first sealing baffle close to the inner edge of the flange is provided with a first sealing gasket for abutting against the inner edge of the flange to seal the first water inlet 1711 when the first sealing element 172 is located at the first position, so that the first sealing element 172 has better sealing performance when being matched with the first water inlet 1711.

It will be appreciated that in embodiments of the present application, where the first housing 171 is provided with a cuff inner edge, the water flow gap 1713 is not limited to being distributed around the entire circumference of the first sealing barrier, for example, at least one water flow groove for water flow may be recessed in the edge of the first sealing barrier in the circumferential direction, and the water flow gap 1713 is defined between the groove wall of the water flow groove and the inner wall of the first housing 171. Further, in the embodiment in which the flow gaps 1713 are distributed around the entire circumference of the first sealing barrier, it is not limited to the manner in which the first housing 171 is provided with the flange inner edge, and for example, the first housing 171 may be provided in such a manner that the inner diameter thereof gradually decreases from the end close to the first water inlet 1711 to the end away from the first water inlet 1711.

Further, the mounting seat 1712 defines a passage (not shown) for allowing water to flow from a side close to the first water inlet 1711 to a side away from the first water inlet 1711, so that the water passing through the water flowing gap 1713 can be sprayed into the basin 120 through the passage defined by the mounting seat 1712.
