[0017] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0018] like Figure 1As shown, the present embodiment proposes a dual water tank system for a vehicle toilet, comprising a wash basin 1, a wash basin water tank 2 for supplying water to the wash basin 1, a toilet 3 and a clean water tank 4 for supplying water to the toilet 3, and also comprising a control device, the control device is provided with a main control switch for controlling the linkage between the wash basin 2 and the clean water tank 4, the water outlet of the clean water tank 4 is connected with the water inlet of the wash basin water tank 2 through a water supply pipe 5, the water supply pipe 5 is provided with a water pump Ⅰ6, and the water pump Ⅰ6 is communicatively connected to the control device, when the main control switch is in the on state, when there is a lack of water in the wash basin water tank 2, the control device controls the water pump Ⅰ6 to start, and the water in the clean water tank 4 enters the wash basin water tank 2 for water supply; when the main control switch is in the off state, the water supply function is turned off.

[0019] Specifically, the hand washing water tank 2 and the hand washing basin 1 are connected by a hand washing water outlet pipe 13, and a water pump II 14 is installed on the hand washing water outlet pipe 13. When the hand washing switch is pressed, the pressing signal (which can be realized by installing a sensor at the pressing position, and the sensor and the control device are communicatively connected. Once the hand washing switch is pressed, the sensor receives the pressing signal. The specific structure of the sensor can refer to the existing structure, and will not be repeated in this article) is transmitted to the control device, and the control device outputs a signal to energize the water pump II 14, pumping water from the hand washing water tank 2 to the faucet for passengers to wash their hands. At the same time, the program can be set in advance through the control device: for example, the flushing time is 3s for each press. The specific setting time is determined according to the actual situation.

[0020] In this way, when the main control switch is turned on, the linkage between the hand washing water tank 2 and the clean water tank 4 is enabled. When the hand washing water tank 2 is short of water, the control device controls the water pump Ⅰ6 to start, and the water in the clean water tank 4 enters the hand washing water tank 2 to replenish water; when the main control switch is turned off, the water replenishment function is turned off. In this way, the water in the clean water tank 4 can be used to replenish water in the hand washing water tank 2. When the water in the clean water tank 4 and the hand washing water tank 2 are both short of water, it is only necessary to replenish water at the same time. The control is convenient, the number of water replenishment is reduced, and the workload of water replenishment is reduced.

[0021] Furthermore, if Figure 1 As shown, the water outlet of the clean water tank 4 is connected to the main water outlet pipe 7, and the water pump I6 is installed on the main water outlet pipe 7. The outlet of the main water outlet pipe 7 is connected to the toilet flushing outlet pipe 10 and the water supply pipe 5 through the water circuit control valve I8 and the water circuit control valve II9 respectively, and the toilet flushing outlet pipe 10 is connected to the toilet 3. When the toilet flushing switch is pressed, the pressing signal is transmitted to the control device, and the control device controls the water circuit control valve I8 to open, and the water pump I6 pumps water from the clean water tank 4 through the toilet flushing outlet pipe 10 to supply the toilet to flush the toilet.

[0022] Among them, a filter is also installed on the main water outlet pipe 7 located at the clean water tank 4 and the water pump Ⅰ 6. Specifically, it is set as a copper filter 20, which can filter impurities in the water, avoid damage to various components on the waterway, and extend the service life.

[0023] Furthermore, a low water level sensor 11 and a high water level sensor 12 are provided in the hand washing water tank 2, and both the low water level sensor 11 and the high water level sensor 12 are communicatively connected to the control device. A water shortage sensor 15 is provided in the clean water tank 4, and the water shortage sensor 15 is communicatively connected to the control device.

[0024] When the main control switch is turned on, when the water level in the hand washing tank 2 is low, the low water level sensor 11 in the hand washing tank 2 transmits a low water level signal to the control device, the control device controls the water circuit control valve Ⅱ9 to open, and the water pump Ⅰ6 pumps water from the clean water tank 4 through the water supply pipe 5 to the hand washing tank 2; when the water level in the hand washing tank 2 reaches the high water level, the high water level sensor 12 of the hand washing tank 2 transmits a signal to the control device, the control device controls the water circuit control valve Ⅱ9 to close, the water pump Ⅰ6 stops working, and the water supply stops; when the clean water tank 4 is empty, the water shortage sensor 15 in the clean water tank 4 transmits a water shortage signal to the control device, the control device controls the power supply of the water pump Ⅰ6 to be disconnected, and the water supply also stops (even if the hand washing tank 2 is short of water, the water supply process is not started), and the toilet 3 cannot be flushed at this time.

[0025] Among them, the hand washing water tank 2 and the clean water tank 4 are both provided with an overflow pipe 16. When water is added to the hand washing water tank 2 and the clean water tank 4, the air in the water tank is first discharged from the overflow pipe 16. When the water is full, the air is emptied. If water is added after it is full, the water will flow out from the overflow pipe 16 to prevent overflow from the water tank when adding water, which will cause trouble for subsequent cleaning.

[0026] In this embodiment, a sewage tank 17 is further included. The water outlets of the wash basin 1 and the toilet 3 are connected to the inlet of the sewage tank 17 through water pipes, and a sewage valve 18 is provided at the outlet of the sewage tank 17.

[0027] In summary, when the main control switch is turned on, the linkage control function of the hand washing tank 2 and the clean water tank 4 is enabled; when the main control switch is turned off, the linkage control function of the hand washing tank 2 and the clean water tank 4 is turned off. It can be freely selected according to actual conditions and has a wide range of applications.

[0028] It should be noted that the water inlets of the hand washing water tank 2 and the clean water tank 4 are both connected to water inlet pipes, and a control valve can be installed on the water inlet pipes. At the same time, the water replenishment pipe 5 is also connected to the water inlet pipe of the hand washing water tank 2 (a water tee 19 can be installed on the water inlet pipe of the hand washing water tank 2).
