[0034] A flushing pipeline 6, one end of which is located in the water tank body 1, and the other end of which is connected to the flushing outlet 4. A pressure pump 61 is provided on the flushing pipeline 6;

[0035] A flood overflow pipeline, wherein the flood overflow pipeline is located outside the water tank body 1 and is connected to the flood overflow port 3 .

[0036] The water inlet valve 5 is connected with the external water inlet pipe to add water into the water tank body 1. A pressure pump 61 is provided on the flushing pipe. The flushing pipe 6 discharges the water in the water tank body 1 from the flushing outlet 4 through the pressure pump 61. The flushing outlet 4 can be connected with the external flushing water pipe 8 and discharge the water in the water tank body 1 into the toilet bowl of the toilet. The water tank body 1 is sealed. A one-way air inlet valve 2 is provided on the water tank body 1 to ensure the balance of air pressure inside and outside the water tank body 1. The overflow port 3 is connected with the overflow pipe. When the water inlet valve 5 is damaged and the water in the water tank exceeds the capacity limit, the water in the water tank can be discharged to the toilet bowl through the overflow port 3 and the overflow pipe to prevent the water in the water tank from overflowing and the bathroom floor from being soaked.

[0037] In some embodiments, Figure 2 and Figure 3 As shown, the embedded water tank also includes a water diversion component 7, which is connected to the water tank body 1, and the water diversion component 7 is provided with a water diversion chamber 711, and the water diversion chamber 711 is provided with a first water outlet 72 and a second water outlet 73, the flushing pipeline 6 is connected with the water diversion chamber 711 through the flushing outlet 4, the overflow port 3 is connected with the water diversion chamber 711, the overflow pipe is connected with the second water outlet 73, and the water diversion component 7 can close one of the first water outlet 72 and the second water outlet 73.

[0038] When not flushing, the water diversion component 7 closes the first water outlet 72 and opens the second water outlet 73, so that the overflow port 3 and the overflow pipe remain connected. When the water in the water tank body 1 exceeds the capacity limit, the water in the water tank can be discharged to the toilet bowl through the overflow port 3 and the overflow pipe to prevent the water in the water tank from overflowing; when flushing, the water diversion component 7 closes the second water outlet 73 and opens the first water outlet 72. At this time, the water in the flushing pipe 6 can only be discharged through the first water outlet 72 to flush the toilet. By setting the water diversion component 7, the overflow pipe and the flushing pipe can be simplified, which is convenient for reducing costs.

[0039] In some embodiments, the spillway 3 is provided with a one-way water outlet valve, which can prevent the water in the water diversion chamber 711 from flowing back into the water tank body 1. By providing a one-way water outlet valve, the water in the flushing pipeline 6 is prevented from flowing back into the water tank body 1 when passing through the water diversion chamber 711.

[0040] In some embodiments, Figure 1-Figure 3 As shown, the water diversion assembly 7 includes a driving motor 74 and a baffle 75, the driving motor 74 is connected to the water tank body 1, the output end of the driving motor 74 is connected to the baffle 75, the baffle 75 is located in the water diversion chamber 711, and the driving motor 74 can drive the baffle 75 to swing so that the baffle 75 closes one of the first water outlet 72 and the second water outlet 73.

[0041] By driving the motor 74 and the baffle 75 to close the first water outlet 72 or the second water outlet 73, and cooperating with the sensor and the controller, the automatic switching of the position of the baffle 75 can be achieved. For example, when the sensor detects that the user is using the toilet, the sensor sends a flushing instruction to the controller, and the controller then sends a switching instruction to the driving motor 74. The driving motor 74 receives the switching instruction and starts working, so that the baffle 75 switches from the state of closing the first water outlet 72 to the state of closing the second water outlet 73. At the same time, the controller controls the booster pump 61 to work, and the water in the water tank body 1 is discharged through the flushing pipeline 6. The water in the flushing pipeline 6 enters the first water outlet 72 through the water diversion chamber 711, and then flushes the toilet through the external flushing water pipe 8. When the flushing is completed, or the sensor detects that the user has left, the controller controls the driving motor 74 to work, so that the baffle 75 switches from the state of closing the second water outlet 73 to the state of closing the first water outlet 72. Through such a setting, the embedded water tank of the present application is adapted to the existing smart toilet.

[0042] In some embodiments, Figure 1-Figure 3As shown, the water diversion component 7 also includes a water diversion member 71, the water diversion chamber 711 is formed in the water diversion member 71, the water diversion member 71 is sealedly connected to the overflow outlet 3 and the flushing outlet 4, the first water outlet 72 and the second water outlet 73 are formed on the water diversion member 71, and the drive motor 74 is connected to the water diversion member 71.

By providing the recessed portion 111 to accommodate the water distribution component 71, the overall height of the embedded water tank can be reduced, the size can be reduced, and space can be saved.

[0045] In some embodiments, Figure 1 As shown, the embedded water tank also includes a flushing water pipe 8, and the flushing water pipe 8 is connected to the first water outlet 72. One end of the flushing water pipe 8 is connected to the toilet bowl, and the other end is connected to the first water outlet 72. The water from the flushing water outlet 4 is discharged to the toilet bowl through the water diversion cavity 711, the first water outlet 72 and the flushing water pipe 8 in sequence.

[0046] In some embodiments, Figure 1-Figure 4 As shown, the water tank body 1 includes a cover plate 11 and a box body 12, and the cover plate 11 and the box body 12 are sealed and connected. The cover plate 11 and the box body 12 are assembled and connected, and a sealant is used to seal the connection between the cover plate 11 and the box body 12, or a sealing rubber ring is provided at the connection between the cover plate 11 and the box body 12 to achieve a sealed setting of the water tank body 1. The cover plate 11 and the box body 12 are connected separately, which facilitates the assembly of parts in the water tank body 1. The cover plate 11 and the box body 12 are sealed and connected. When the water inlet valve 5 fails, the water in the water tank can only be discharged from the overflow port 3, and will not flow out from the connection between the cover plate 11 and the box body 12.

[0047] In some embodiments, the cover plate 11 and the box body 12 are sealed and connected by ultrasonic welding.

[0048] In some embodiments, Figure 3 As shown, the flood spillway 3 and the flushing outlet 4 are both arranged on the cover plate 11 .

[0049] In some embodiments, Figure 2 and Figure 3 As shown, the cover plate 11 is recessed into the box body 12 to form a recessed portion 111 .

When working, the water in the box body 12 can lift the floating seat 21, and the floating seat 21 covers the air inlet. The air port 112 is used to seal the air inlet 112. When flushing, the water level in the box body 12 decreases, and the floating seat 21 falls, driving the connecting shaft 22 and the clamping part 23 to fall. Since the diameter of the clamping part 23 is larger than the diameter of the mounting hole 113, the clamping part 23 stops falling when it falls to the mounting hole 113. After the floating seat 21 falls, the air inlet 112 is not blocked. At this time, the outside air can enter the water tank body 1 through the air inlet 112 for air replenishment to maintain the balance of the air pressure inside and outside the water tank body 1.
