Description

Technical Field

[0001] The utility model relates to an intelligent toilet water tank. Background Art

[0002] To prevent siphonage, smart toilet tanks typically increase their height. This increases the distance between the water inlet and the liquid level, making it less likely for the liquid to backflow from the inlet. However, smart toilets are becoming increasingly lightweight, leaving insufficient space for tank installation. Therefore, taller tanks are no longer suitable for smart toilets. Utility Model Content

[0003] The utility model provides a smart toilet water tank with an anti-siphon function and a small height, which overcomes the shortcomings of the background technology. The technical solution adopted by the utility model to solve the technical problem is:

[0004] The intelligent toilet water tank includes a lower shell and an upper cover, the lower shell is provided with a water outlet, the top of the upper cover is provided with a water spray chamber and a water collection chamber, the water spray chamber is arranged adjacent to the water collection chamber, the side wall of the water spray chamber is provided with a water spray port, and the middle side wall separating the water spray chamber and the water collection chamber is provided with a water receiving port, the water spray port and the water receiving port are opposite to each other so that water can be ejected from the water spray port to the water receiving port, a first overflow port is provided at the bottom of the water spray chamber, the bottom of the water collection chamber leads to the lower shell, and a second overflow port is provided on the top of the lower shell, and the height of the water receiving port is greater than the height of the second overflow port.

[0005] In a preferred embodiment: the water spray port is plugged into the water inlet connector.

[0006] In a preferred embodiment, the lower shell is provided with an overflow channel on the side, and the first overflow port and the second overflow port lead into the overflow channel.

[0007] In a preferred embodiment, the length of the lower shell is greater than its height.

[0008] In a preferred embodiment, it also includes a liquid level float for measuring the liquid level in the lower shell and a solenoid valve for opening and closing the water inlet joint, and the liquid level float and the solenoid valve are connected to the main control board signal.

[0009] In a preferred embodiment: it also includes a water pump, the lower shell is provided with a water pump inlet and a water pump outlet corresponding to the water pump, the water pump inlet is connected to the water outlet, and the water pump is connected to the main control board signal.

[0010] In a preferred embodiment: a drain port is provided at the bottom of the lower shell, and the drain port is closed by a sealing plug.

[0011] In a preferred embodiment, the upper cover and the lower shell are buckled together, and a sealing strip is provided between the two.

[0012] In a preferred embodiment, the upper cover is provided with a descaling liquid adding port.

[0013] In a preferred embodiment, the upper cover is provided with a descaling circulating water interface.

[0014] Compared with the background technology, this technical solution has the following advantages:

[0015] 1. The water spray port and water inlet are located on two opposing side walls, forming a partition in between to prevent water in the water tank from flowing back into the water spray port. Furthermore, the height of the water inlet is greater than that of the second overflow port. If water continues to flow in, the liquid level in the water tank can only reach the second overflow port at most, and cannot rise to the water inlet, further preventing siphon backflow. Furthermore, the provision of a water spray chamber and a water collection chamber to form opposing water spray ports and water inlets creates a water inlet waterway partition. Therefore, the structure of the water spray chamber and water collection chamber is not only simple, but also does not occupy excessive height space, thereby ensuring a low overall height of the water tank and enabling a flat and thin design suitable for smart toilets.

[0016] 2. The overflow channel can lead the water overflowing from the lower shell and the water falling into the spray chamber when the water nozzle is spraying to the outside of the water tank, with a simple and compact structure.

[0017] 3. When the liquid level in the lower shell is lower than the set height, the liquid level float sends a water replenishment signal. After receiving the water replenishment signal, the main control board sends an instruction to open the water inlet joint to the solenoid valve. When the liquid level reaches the set height, the liquid level float sends a water stop signal. After receiving the water stop signal, the main control board sends an instruction to close the water inlet joint to the solenoid valve, so that the water tank is automatically and accurately replenished with water.

[0018] 4. Open the sealing plug and drain the water in the water tank through the drain port, making it easier to clean the water tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Figure 1 A three-dimensional exploded diagram of the smart toilet water tank is drawn.

[0021] Figure 2 Draws Figure 1 The diagram shows a partial cross-section of the smart toilet tank from a top view perspective.

[0022] Figure 3 Draws Figure 1 The diagram shows a cross-sectional view of the smart toilet tank from the main view angle. DETAILED DESCRIPTION

[0023] Please refer to Figures 1 to 3 The smart toilet water tank includes a lower shell 10 and an upper cover 20. The lower shell is used to hold water and is provided with a water outlet 11. The upper cover is used to cover the upper opening of the lower shell. The top of the upper cover 20 is provided with a water spray chamber 21 and a water collection chamber 22. The water spray chamber and the water collection chamber are arranged adjacent to each other. A water spray port 23 is provided on the side wall of the water spray chamber 21. A water inlet 24 is provided on the middle side wall separating the water spray chamber 21 and the water collection chamber 22. The water spray port 23 and the water inlet 24 are opposite to each other so that water can be ejected from the water spray port 23 to the water inlet 24. A first overflow port 25 is provided at the bottom of the water spray chamber 21. The bottom of the water collection chamber 22 is connected to the lower shell 10. A second overflow port 12 is provided at the top of the lower shell 10. The height of the water inlet 24 is greater than that of the second overflow port 12.

[0024] When the water tank is replenished with water, water is ejected from the water spout 23 toward the water inlet 24, enters the water collection chamber 22, and falls into the lower shell 10. The water spout 23 splashes onto the water side of the water spray chamber 21 and flows out from the first overflow port 25. If a malfunction causes the water inlet to be unable to be closed, when the water in the lower shell 10 rises slightly to the second overflow port 12, it will flow out from the second overflow port 12. If siphoning occurs, on the one hand, the liquid level in the lower shell 10 is below the water inlet 24, and with the intervention of the second overflow port 12, water basically cannot flow back to the water inlet 24. Moreover, the water spout 23 and the water inlet 24 are respectively arranged on two opposite side walls. Even if water flows back from the water inlet 24, it can only enter the water spray chamber 21 and then be discharged from the first overflow port 25, and will not enter the water spout 23.

[0025] Preferably, the water spray port 23 is connected to a water inlet connector 26 , and the water inlet connector 26 facilitates water connection to the water tank. Water sprayed from the water spray port 23 has the same effect as water sprayed from the water inlet connector 26 .

[0026] Preferably, the lower shell 10 is provided with an overflow channel 13 on the side, and the first overflow port 25 and the second overflow port 12 lead into the overflow channel 13. The overflow channel 13 can be connected to the toilet bowl of the toilet.

[0027] Preferably, the length of the lower shell 10 is greater than its height. As can be clearly seen from the accompanying drawings, the water tank as a whole is a flat structure.

[0028] Preferably, the system further includes a liquid level float 30 for measuring the liquid level within the lower housing 10 and a solenoid valve 40 for opening and closing the water inlet connector 26 (or the water outlet 23). The liquid level float 30 and the solenoid valve 40 are signal-connected to a main control board (not shown). Further preferably, the system further includes a water pump 50. The lower housing 10 is provided with a water pump inlet nozzle 14 and a water pump outlet nozzle 15 corresponding to the water pump 50. The water pump inlet nozzle 14 is connected to the water outlet 11, and the water pump 50 is signal-connected to the main control board. During use, the main control board sends a signal to the water pump 50, and the water pump 50 starts and pumps water. When the liquid level in the lower shell 10 drops to a predetermined height, the liquid level float 30 sends a signal to the main control board, and the main control board sends an instruction to the solenoid valve 40 to open the water inlet connector 26 for water replenishment. When the liquid level in the lower shell 10 rises to a predetermined height, the liquid level float 30 sends a signal to the main control board, and the main control board sends an instruction to the solenoid valve 40 to close the water inlet connector 26.

[0029] Preferably, a drain port is provided at the bottom of the lower shell 10, and the drain port is closed by a sealing plug 16. When cleaning the water tank, if it is necessary to drain the accumulated water in the lower shell, the sealing plug 16 can be opened manually.

[0030] Preferably, the upper cover 20 is buckled with the lower shell 10 , and a sealing strip 60 is provided between the two.

[0031] Preferably, the upper cover 20 is provided with a descaling liquid addition port 27. Further preferably, the upper cover is provided with a descaling circulating water port 28. During descaling operation, liquid can be added through the descaling liquid addition port 27, and the descaling water can flow back to the water tank through the descaling circulating water port 28 for reuse.

[0032] The above description is merely a preferred embodiment of the present invention and therefore cannot be used to limit the scope of implementation of the present invention. In other words, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
