[0020] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0022] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0023] Combination Figures 1 to 3 As shown, the present embodiment provides a RV water supply system, which can separate and classify the water used in the RV, thereby effectively meeting the various water needs of the RV. Specifically, the RV water supply system provided in the present embodiment includes a fresh water tank 11, a grey water tank 12, a grey water tank 13 and a black water tank 14 installed in the RV; the drain pipes of the bathroom 21 and / or the vegetable sink 22 in the RV are connected to the water inlets of the grey water tank 12 and the grey water tank 13 through the filter 3, the water outlet of the grey water tank 12 is connected to the on-board toilet 23 through a pipe, and the sewage pipe of the on-board toilet 23 is connected to the water inlet of the black water tank 14. Preferably, a water pump 4 is also provided on the pipeline between the grey water tank 12 and the vehicle toilet 23. More preferably, the sewage pipe of the vehicle toilet 23 is connected to the water inlet of the black water tank 14, and the clean water tank 11 is connected in parallel to the water pump 4 through the solenoid valve 111 and the one-way valve 43 and the grey water tank 12 through the solenoid valve 121.

[0024] The RV water supply system set up in the above manner can process the domestic water generated by the bathroom 21 and / or the kitchen sink 22 through the filter 3 and store it in the grey water tank 12 and the gray water tank 13 respectively, and then use it for flushing the on-board toilet through the action of the water pump 4, thereby effectively avoiding the waste of clean water caused by directly using on-board clean water to flush the toilet under the existing technology, thereby effectively improving the utilization rate of clean water in the RV.

[0025] In addition, the arrangement of connecting the water outlets of the clean water tank 11 and the medium water tank 12 in parallel with the water pump 4 also provides a better water supply for the use of the vehicle toilet 23 when the medium water tank 12 is insufficiently filled with water, that is, when there is no medium water available in the medium water tank 12, the solenoid valve 111 connected to the clean water tank 11 can be opened, and then the clean water in the clean water tank 11 is introduced into the vehicle toilet 23 for use under the action of the water pump 4. In this embodiment, the arrangement of the solenoid valve 111 and the one-way valve 43 can effectively prevent the medium water in the medium water tank 12 from flowing into the clean water tank 11.

[0026] More specifically, as a preference, the filter 3 in this embodiment is provided with a grey water outlet 31 and a grey water outlet 32, the grey water outlet 31 is connected to the grey water tank 12 through a water pipe, and the grey water outlet 32 ​​is connected to the grey water tank 13 through a water pipe.

[0027] Further preferably, the filter 3 in this embodiment includes a gravity filter tank 33 arranged in a filter housing 36 and replaceably arranged in a cavity of the filter housing 36; the upper end surface of the gravity filter tank 33 and the side wall of the upper port of the filter housing 36 constitute a gray water collection chamber 34, the side wall of the gray water collection chamber 34 is provided with a gray water outlet 32, and the bottom of the filter housing 36 is provided with a medium water outlet 31, the gravity filter tank 33 is evenly distributed with filter holes, and the upper end surface of the gravity filter tank 33 is extended around a positioning wall 331 overlapping the gray water collection chamber 34. Preferably, the gravity filter tank 33 in this embodiment can be set as a ceramic filter element, and can also be set as a stainless steel microporous filter membrane or a foam porous titanium alloy or other materials as needed.

[0028] With the above structural design, the grey water flowing into the grey water collection chamber 34 is filtered by the gravity filter tank 33 to form grey water, and then flows into the grey water tank 12 through the grey water outlet 31 .

[0029] Furthermore, in order to perform initial filtration on the gray water flowing into the gray water collection chamber 34, the present embodiment is preferably provided with a filter cover 35 at the upper port of the gray water collection chamber 34, and the filter cover 35 has a plurality of fan-shaped filter holes 351 evenly distributed circumferentially. The filter 3 designed in this way can be installed at the water outlet of the bathroom 21, the vegetable sink 22, and the wash basin 24, so that the water flows through the filter cover 35 for initial filtration and then flows into the gray water collection chamber 34, and then further filtered through the gravity filter tank 33, and the excess gray water in the gray water collection chamber 34 flows into the gray water tank 13 through the gray water outlet 32.

[0030] Furthermore, the present embodiment can also recycle and reuse the condensed water discharged from the air conditioning condensation drain pipe 41 of the air conditioning 40 in the RV. Specifically, the water inlet of the clean water tank 11 is connected to the air conditioning condensation drain pipe 41 provided in the RV through the filter cartridge 42 and the solenoid valve 44; the water outlet of the clean water tank 11 is connected to the water pump 4 in parallel with the medium water tank 12 through the solenoid valve 111 and the one-way valve 43. The air conditioning condensation drain pipe 41 can also be connected to the water inlet of the medium water tank 12 through the solenoid valve 45. In this way, the condensed water generated by the RV air conditioning during operation can be fully utilized.

[0031] In addition, in this embodiment, ultraviolet disinfection lamps 5 are arranged in the medium water tank 12 and the clean water tank 11 to ensure water safety and reduce the spread of bacteria and viruses.

[0032] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific implementations of the present invention without paying creative labor, and these methods will fall within the scope of protection of the present invention.
