[0002] The water system of an RV generally refers to the water use system and recycling system. During long-distance travel, it is crucial to control and save water resources. Especially when traveling to areas with insufficient water resources, it is usually not possible to replenish water conveniently. Therefore, it is extremely important to extend the use cycle of purified water and save purified water as much as possible when using it.

[0003] In the existing RV water system, kitchen and bathroom faucets are generally equipped with hot and cold water.

In the existing technical means, in order to achieve instant hot water when hot water is used, a circulating pump is set to circulate the hot water so that there is always hot water in the hot water pipe. However, for some mobile devices such as RVs, the installation of such a device will greatly increase the energy consumption of the vehicle and cause energy waste. Summary of the invention

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figure 1-Figure 6 .

[0023] A motorhome water flow adaptive circulation device comprises a faucet 1, a switch lever 2, a hot water pipe 3 connected to the faucet 1 and a faucet seat 4. The switch lever 2 is rotatably arranged on the faucet seat 4, the hot water pipe 3 is fixed on the faucet seat 4, and is opened and closed with the faucet 1 through the valve core on the switch lever 2. This is the existing technology of the faucet and will not be elaborated on here.

[0024] like Figure 1 As shown, the switch lever 2 is turned to the left to discharge hot water, and turned to the right to discharge cold water; the water outlet of the faucet 1 is provided with a circulation joint 101 which is connected to the faucet after rotation. Specifically, the circulation joint 101 is a bend pipe joint, such as Figure 3 As shown, a swing plate 103 is fixedly provided on the circulation joint 101, and a positioning plate 102 is fixedly provided on the faucet 1. The straight pipe part of the circulation joint 101 is rotatably provided on the positioning plate 102. After the circulation joint 101 is driven to rotate a certain angle by the swing plate 103, the water inlet corresponding to the curved pipe part of the circulation joint can be docked with the water outlet of the faucet 1, thereby realizing the docking and connection between the faucet 1 and the circulation joint 101.

[0025] The circulation joint 101 is connected to the hot water pipe 3 through the circulation pipe 5. Specifically, the hot water pipe 3 includes a venturi tube 301, and a suction pipe 302 is transversely connected to the tube wall of the venturi tube 301. The circulation pipe 5 is connected to the suction pipe 302, and a solenoid valve 303 is provided between the circulation pipe 5 and the suction pipe 302. When the solenoid valve 303 is in an open state, hot water generates suction force at the suction pipe 302 after passing through the venturi tube 301, thereby circulating the water at the circulation joint 101 into the hot water pipe 3 for circulation.

[0026] The faucet seat 4 is provided with a rotating plate 401, and the rotating plate 401 is connected to the swing plate 103 on the circulation joint 101 through a pull rope 402. After the rotating plate 401 rotates, the swing plate 103 is driven to swing, so that the circulation joint 101 is connected to the water outlet of the faucet 1; the rotating plate 401 is provided with a swing rod 403 that is driven when the switch lever 2 is moved to the hot water side. Figure 1 and Figure 5As shown, the switch lever 2 is provided with a magnetic strip 201, and the swing rod 403 is a ferromagnetic rod. In the initial state, the magnetic strip 201 and the swing rod 403 are in a micro-contact adsorption state. When the hot water switch is turned on, the switch lever 2 is moved to Figure 1 After swinging to the left in the direction shown, the swing rod 403 is driven to move, so that the rotating plate 401 rotates, thereby driving the swing plate 103 to swing, and connecting the water outlet of the faucet 1 to the hot water circulation pipe 5.

[0027] The faucet seat 4 is provided with a limit block 404 for limiting the rotation of the rotating plate 401 to the other side. Figure 5 As shown, the rotating plate 401 can only rotate to the left, and is restricted by the limit block 404 when rotating to the right. That is, when the switch lever 2 is moved in the cold water direction, the rotating plate 401 cannot be triggered. At this time, the circulation joint 101 is also misaligned with the water outlet of the faucet 1, so that cold water can be discharged from the faucet 1 normally.

[0028] The faucet 1 is provided with a plurality of guide connecting plates 104 for positioning the pull rope 402 and the circulation pipe 5. Figure 1 and Figure 2 As shown, one end of the pull rope 402 is connected to the swing plate 103, and the other end is passed through the above-mentioned guide connecting plate 104 in turn and then fixedly connected to the outer edge of the rotating plate 401, so that the rotating plate 401 can achieve displacement drive of the pull rope 402; a reset spring 105 is provided between the circulation joint 101 and the positioning plate 102.

[0029] The positioning plate 102 is provided with a pin rod 106 which cooperates with the swing plate 103. The upper end of the pin rod 106 is a spherical rod body, and the lower end penetrates the upper wall of the positioning plate 102 and is placed in the movable cavity 108 in the positioning plate 102. Figure 4 As shown, an arc-shaped elastic sheet 109 is provided in the movable cavity 108, and both ends of the elastic sheet 109 are fixedly clamped on the two side walls of the movable cavity 108, and the arc-shaped protruding part is connected to the lower end of the pin rod 106, and the lower end of the pin rod 106 is clamped on the elastic sheet 109 through an annular groove.

[0030] A pin sleeve 107 is rotatably provided on the swing plate 103; a pin hole 112 matching with the pin rod 106 is provided in the pin sleeve 107, the pull rope 402 is passed through the upper end of the pin sleeve 107, and a pull rope guide plate 113 matching with the pull rope 402 is provided on the positioning plate 102; when the swing plate 103 swings, the upper end of the pin rod 106 is squeezed to deform and compress the elastic sheet 109, and then when the pin rod 106 and the small hole 112 on the pin sleeve 107 are coaxial, the elastic sheet 109 is reset, and the pin rod 106 is pushed upward, so that the swing plate 103 is locked in this position, that is, the locking of the water outlet of the faucet 1 and the circulation joint 101 is achieved when they are connected.

[0031] The elastic sheet 109 is a bimetallic sheet. A guide rod 110 is provided at one end of the elastic sheet 109 close to the pipe of the faucet 1. One end of the guide rod 110 is fixedly connected to the elastic sheet 109, and the other end is passed through the wall of the faucet 1 and then placed in the water outlet of the faucet 1. The guide rod 110 is a temperature conducting rod that can quickly conduct the temperature to the elastic sheet 109. When the water outlet is warm water, the guide rod 110 can conduct the temperature to the elastic sheet 109 to cause the elastic sheet 109 to deform. Figure 4 The arc protrusion shown is deformed downward in the reverse direction, so that the pin rod 106 slides downward, unlocking the lock between the swing plate 103 and the positioning plate 102. At this time, the circulation joint 101 is reset by the reset spring 105, and the faucet 1 can discharge warm water after being turned on, so that the user can use it immediately.

[0032] A contact switch 111 is provided at the bottom of the movable cavity 108 to cooperate with the deformed elastic sheet 109. The contact switch 111 is electrically connected to the electromagnetic valve 303. The electromagnetic valve 303 is a one-way electromagnetic valve, and its flow direction is from the circulation pipe 5 to the suction pipe 302. When the contact switch 111 is triggered, the electromagnetic valve 303 can be closed to block the circuit between the circulation pipe 5 and the suction pipe 302, that is, when the circulation joint 101 is reset and moved to one side of the faucet 1, the circulation pipe 5 circuit is blocked, so that the circulation joint 101 will not leak.

[0033] Method for using a motorhome water flow adaptive circulation device as described above: S1: Initially, the circulation joint 101 and the water outlet of the faucet 1 are in a staggered state. When hot water is needed, the operator turns the switch lever 2 toward the hot water direction. Figure 1 Move to the left as shown; S2: The magnet 201 on the switch lever 2 attracts the swing rod 403, thereby driving the rotating plate 401 to rotate a certain angle, and then the switch lever 2 is moved again to separate from the swing rod 403; S3: When the rotating plate 401 rotates to a certain angle, the swing plate 103 is pulled by the pull rope 402 to rotate the circulation joint 101 to a certain angle, so that the circulation joint 101 is docked with the faucet 1. At this time, the pin rod 106 is inserted into the pin hole 112, so that the swing plate 103 and the positioning plate 102 are relatively fixed; S4: hot water flows into the faucet seat 4 through the hot water pipe, and the cold water in the pipe enters the faucet 1 and then enters the circulation pipe 5. At this time, the Venturi tube 301 circulates and draws the cold water in the circulation pipe 5 into the Venturi tube 301 due to the suction force of the hot water flow, and the cycle repeats until the water temperature at the water outlet of the faucet 1 reaches a certain temperature; S5: When the water temperature at the water outlet reaches the standard, the elastic sheet 109 is triggered to deform elastically through the guide rod 110, so that the guide rod 110 transmits the temperature to the elastic sheet 109, causing the elastic sheet 109 to deform. Figure 4 The arc protrusion shown is deformed downward in the reverse direction, so that the pin rod 106 slides downward, unlocking the lock between the swing plate 103 and the positioning plate 102. At this time, the circulation joint 101 is reset by the reset spring 105, and the faucet 1 can discharge warm water after being turned on, so that the user can use it immediately.
