[0008] Furthermore, a limiting column is arranged on the axial ring of the main body.

[0009] Furthermore, three limiting columns are arranged at intervals.

[0010] Beneficial effects achieved by the utility model:

[0011] The main body structure of the utility model adopts a clamping structure to achieve fast and lossless installation to adapt to siphon toilets. A water guide groove is provided on the main body, and water is guided into the water guide pipe through the water guide groove to replenish the toilet. A clamping edge and a reinforcing rib are provided on the main body to improve the strength of the main body; a limit column is provided on the side of the main body, and the limit column is supported on the inner wall of the water outlet cavity of the valve body to ensure the stability of the installation of the main body and the valve body.

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] A water replenishment structure for a siphon toilet, such as Figure 1-Figure 5 As shown, it includes a body 1, a connecting pipe 2 and a water pipe 3. The cross section of the body 1 is a C-shaped structure. The connecting pipe 2 is arranged at the upper end of the body 1. A water guide groove 11 is recessed on the side wall of the body 1. The connecting pipe 2 is connected to the water guide groove 11. The water guide pipe 3 is connected to the connecting pipe 2. The water is guided into the toilet by the water guide pipe 3. The water guide groove 11 is a curved surface structure. Water enters the water guide groove 11 and is guided into the water guide pipe 3 along the water guide groove 11. It avoids the water from being hit and causing disorder due to the angular structure.

[0021] In the above embodiment, if Figure 1-Figure 5As shown, the water replenishment structure is used in conjunction with the water inlet valve. The water replenishment structure is a modified component of the existing water inlet valve, which makes it suitable for siphon toilets. After the flushing is completed, a portion of the water can be introduced into the toilet through the water replenishment structure to form a liquid seal. Among them, the main body 1 and the water inlet valve adopt a clamping structure. Specifically, the upper end of the main body 1 is provided with a clamping edge 12 protruding outward, and at least two clamping hooks 13 are protruding upward on the upper end surface of the main body 1. The clamping edge 12 is used to strengthen the strength of the main body, and the clamping hook 13 cooperates with the clamping edge 12 to clamp the water inlet valve. The main body 1 is installed at the water outlet of the valve body.

[0022] In one embodiment, if Figure 1-Figure 5 As shown, in order to further improve the strength of the main body 1, a reinforcing rib 14 is radially protruded from the lower end of the main body 1.

[0023] In one embodiment, if Figure 1-Figure 5 As shown, the axial ring of the body 1 is provided with a limit column 15. A gap needs to be provided between the body 1 and the inner wall of the valve body outlet cavity, so that most of the water flows downward into the water tank from the gap, and part of the water flows into the toilet through the water guide groove 11 and the water guide pipe 3.

[0024] In the above embodiment, if Figure 1-Figure 5 As shown, three limiting posts 15 are arranged at intervals.

[0025] When the utility model is used, Figure 1-Figure 5 As shown, the main body 1 is connected to the valve body, and water enters from the water inlet end of the valve body and then reaches the outlet end. Since the main body 1 is provided with a water guide groove 11, part of the water is diverted to the water guide pipe 3 through the water guide groove 11, and then guided into the toilet through the water guide pipe 3. For a water tank without a water replenishment device, after the user flushes, the toilet will not get more water as the drain valve falls back. However, with the water replenishment function, water will still flow into the toilet until the water inlet valve is closed, and then the water replenishment will stop. Through the above structure, the water tank product is more suitable for siphon toilets.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. If the present invention is modified or replaced by equivalents without departing from the spirit and scope of the present invention, they should be included in the scope of protection of the claims of the present invention.
