TECHNICAL FIELD
[0001] The utility model relates to closestool technical field especially a multifunctional water tank body structure. BACKGROUND
[0002] The closestool water tank needs to store water before flushing, and when the stored water is too much or the water inlet switch does not close in time, the closestool water tank will overflow. The traditional overflow water is connected to the closestool pot surface through a pipeline and is discharged from the closestool pot surface, which can solve the overflow problem of the closestool water tank. However, such overflow water discharge method has some shortcomings, mainly manifested in that the height of the water tank needs to be higher than the closestool pot surface, and the existing intelligent closestools have a trend of making the water tank top cover low and flat. In addition, the overflow water is discharged through the closestool pot surface, which will leave marks on the closestool pot surface after a long time. Therefore, the utility model provides a water tank structure that does not need to discharge overflow water through the closestool pot surface, which can solve the above technical problems. SUMMARY
[0003] The utility model provides a kind of water tank structure that does not need to discharge overflow water through closestool pot surface to solve the above technical problems.
[0004] A multifunctional water tank body structure includes a water tank body, a tank cover and a drain seat.
[0005] The water tank body is provided with a water storage cavity, and the water storage cavity is provided with an overflow pipe. The bottom end of the overflow pipe extends out of the bottom of the water tank body and forms an overflow port facing downward, and the top end forms a water inlet port facing upward. The excess water in the water tank body can be discharged through the overflow pipe without passing through the closestool pot surface.
[0006] The tank cover covers the top of the water outlet cavity and is provided with a flow guide pipe. The bottom end of the flow guide pipe extends into the water storage cavity and is located at the top of the water inlet port of the overflow pipe or communicates with the water inlet port of the overflow pipe. The top of the flow guide pipe forms a water inlet interface that can be connected to the drain port on the upper edge of the closestool pot surface. When the S-bend of the closestool is blocked, the water in the closestool pot surface can be discharged through the flow guide pipe and the overflow pipe, preventing sewage from overflowing from the closestool pot surface.

[0040] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0041] Please see Figures 1 to 9 A multifunctional water tank 1 body structure includes a water tank 1 body and a drain seat 3.
[0042] The water tank 1 body is provided with a water storage cavity 11, and an overflow pipe 12 is provided in the water storage cavity 11. The bottom end of the overflow pipe 12 extends from the bottom of the water tank 1 body and forms an overflow port 121 with the opening facing downward, while the top end forms a water inlet with the opening facing upward. Excess water in the water tank 1 body can be discharged through the overflow pipe 12 without passing through the toilet bowl 41.
[0043] The tank cover 2 seals the top of the water outlet chamber and is equipped with a guide pipe 21, such as... Figure 2 As shown, the bottom end of the guide pipe 21 extends into the water storage chamber 11 and is located at the top of the inlet of the overflow pipe 12, or is connected to the inlet of the overflow pipe 12. The top forms an inlet interface that can be connected to the drain outlet 411 on the upper edge of the toilet bowl 41. When the S-bend 42 of the toilet is blocked, the water in the toilet bowl 41 can be discharged through the guide pipe 21 and the overflow pipe 12, preventing sewage from overflowing from the toilet bowl 41.
[0044] The drain seat 3 is provided with a main sewage channel 31 and a branch sewage channel 32. The main sewage channel 31 has an upward-facing receiving interface and a downward-facing sewage outlet, which are respectively used to connect to the outlet of the toilet's S-bend 42 and the inlet of the ground sewer. The branch sewage channel 32 is located between the receiving interface and the sewage outlet of the main sewage channel 31. One end of the branch sewage channel 32 is connected to the main sewage channel 31, and the other end has an upward-facing auxiliary function connection port 321. During installation, the drain seat 3 is placed at the bottom of the water tank 1, and the auxiliary function connection port 321 is connected to the overflow port 121.
[0045] To reduce molding difficulty, based on the above embodiment, the end of the sewage branch 32 is provided with a mold core exit port 322, and the mold core exit port 322 is provided with a plug 323, which provides a mold core exit port 322 for molding the sewage branch 32, thereby reducing the complexity of the mold and the molding difficulty. In addition, the plug 323 and the mold core exit port 322 are assembled together by interference fit, thread, welding, bonding or snap fastening.
[0046] Because the diameter of the sewage branch 32 is small, to avoid a small opening and low flow rate in the additional functional connection port 321, based on the above embodiment, the additional functional connection port 321 is elongated, forming a larger opening. In other embodiments, the additional functional connection port 321 is internally divided into at least two channels, which can connect to different drainage or venting components. Furthermore, the water storage chamber 11 is also equipped with an venting pipe 13 extending from the cover 2, such as... Figure 3 , Figure 5 and Figure 6 As shown, the bottom end of the exhaust pipe 13 is also connected to the additional function connection port 321, while the top end is connected to the odor suction pump on the toilet. The odor suction pump can suck up the odor from the toilet bowl surface 41 and discharge it through the exhaust pipe 13 and the overflow pipe 12. It should be noted that the deodorization device formed by the odor suction pump is an existing smart toilet function and is not a technical improvement point of this application. It will not be elaborated here. This application only improves the exhaust pipe and path connected to its exhaust end.
[0047] To prevent sewage or odor from overflowing, in one embodiment, a one-way valve 33 is installed in the additional functional connection port 321. The one-way valve 33 seals the overflow port 121 when there is no water in the overflow pipe 12 and opens the overflow port 121 when there is water in the overflow pipe 12, thus preventing sewage from the displacement device from entering the water tank 1 body. Preferably, a mounting bracket is provided in the additional functional connection port 321. The mounting bracket has a vertical telescopic hole. The one-way valve 33 includes a telescopic rod 331 and a spring 332. The top of the telescopic rod 331 is provided with an overflow cover 333. A sealing gasket 334 is installed on the top of the overflow cover 333. The bottom end of the telescopic rod 331 is inserted into the telescopic hole. The spring 332 is sleeved between the telescopic rods 331, with the top pressing against the overflow cover 333 and the bottom pressing against the mounting bracket. The spring 332 provides force for the overflow cover 333 to seal the overflow port 121.
[0048] To improve drainage flow, based on the above embodiment, the connection between the sewage branch 32 and the main sewage channel 31 is located at the top of the main sewage channel 31, and the sewage branch 32 has an angle A with the horizontal plane, the angle A being 1°~3°, preferably 2°, which is beneficial for drainage and can also prevent sewage from overflowing from the branch in the main sewage channel 31.
[0049] In one embodiment, such as Figures 7 to 9 As shown, the drain seat 3 is a displacement device that enables the toilet to be moved and installed. It includes a receiving section 34, at least one extension pipe 35, and a sewage discharge section 36 that are connected in sequence. This can improve the displacement length and flexibility of the drain seat 3. In addition, to increase the installation firmness and stability of the drain seat 3, a support seat is provided around the receiving interface, and a flange is provided around the sewage discharge port, both of which can provide reliable support for the drain seat 3.
[0050] Based on the above embodiments, the multifunctional water tank 1 body structure also includes a toilet body 4. The horizontal cross-section of the water tank 1 body is U-shaped, and the middle part of the water tank 1 body is concave to form a clearance opening for accommodating the S-bend 42 of the toilet body 4. Thus, a compact installation structure can be formed between the water tank 1 body and the toilet body 4 to avoid wasting space.
[0051] To enhance drainage, in one embodiment, a drain outlet 411 is provided on the upper edge of the bowl 41 of the toilet body 4. The drain outlet 411 extends to the outer periphery of the toilet body 4 and is connected to the water inlet of the guide pipe 21 through a pipe. When the S-bend 42 of the toilet is blocked, the water in the bowl 41 of the toilet can be discharged through the guide pipe 21 and the overflow pipe 12, preventing sewage from overflowing from the bowl 41 of the toilet.
[0052] In addition, such as Figure 4 As shown, the toilet body 4 has a mounting cavity 43 with a mounting base 5 for installing electronic components. The mounting base 5 has a collection groove 51 with a downward-extending water guide. The water guide is located directly above the water inlet of the guide pipe 21. When water enters the mounting cavity 43, the collection groove 51 can collect the water and discharge it from the guide pipe 21 and the overflow pipe 12, thus preventing the electronic components from being wetted by water.
[0053] The water tank 1 provided by this utility model has multiple functions. On the one hand, by setting an overflow pipe 12 extending downward, excess water in the water tank 1 can be directly discharged into the sewer without passing through the toilet bowl 41, thus avoiding watermarks on the toilet bowl 41. On the other hand, a guide pipe 21 is also provided, which can discharge the sewage that is about to overflow from the toilet bowl 41 through the overflow pipe 12 when the toilet is blocked, thus preventing sewage from overflowing.
