Description

Technical Field

[0001] This invention relates to the field of RV water supply system technology, and in particular to an RV water flow adaptive circulation device. Background Technology

[0002] The water system of a motorhome generally refers to the water usage system and recycling system. During long-distance travel, water resource control and conservation are crucial, especially when traveling to areas with insufficient water resources, where it is usually not easy to replenish water. Therefore, extending the service life of the purified water and conserving purified water as much as possible during use are extremely important.

[0003] In existing RV water systems, kitchen and bathroom faucets are generally equipped with both hot and cold water. Usually, when using hot water, the cold water in the pipes must be released first before hot water is available, and the released cold water is wasted. In current technology, to achieve instant hot water when needed, a circulation pump is installed to circulate the hot water, so that there is always hot water in the hot water pipes. However, for mobile devices such as RVs, installing such a device will significantly increase the vehicle's energy consumption, resulting in energy waste. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a mobile home water flow adaptive circulation device.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a mobile home water flow adaptive circulation device, comprising a faucet, a switch lever, a hot water pipe connected to the faucet, and a faucet seat;

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: See also Figures 1-6 .

[0029] A mobile home water flow adaptive circulation device includes 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 mounted on the faucet seat 4, and the hot water pipe 3 is fixed on the faucet seat 4. The faucet 1 is opened and closed via a valve core on the switch lever 2. This is existing technology for faucets and will not be described in detail here.

[0030] like Figure 1 As shown, the switch lever 2, when moved to the left, dispenses hot water, and when moved to the right, dispenses cold water; the faucet 1 has a circulation connector 101 on its outlet that connects to it when rotated. Specifically, the circulation connector 101 is a bent pipe connector, such as... Figure 3 As shown, a swing plate 103 is fixedly provided on the circulation connector 101, and a positioning plate 102 is fixedly provided on the faucet 1. The straight pipe part of the circulation connector 101 is rotatably mounted on the positioning plate 102. After the circulation connector 101 is driven to rotate by the swing plate 103 to rotate a certain angle, the inlet corresponding to the bent pipe part of the circulation connector can be connected with the outlet of the faucet 1, thereby realizing the connection between the faucet 1 and the circulation connector 101.

[0031] The circulation connector 101 is connected to the hot water pipe 3 via the circulation pipe 5. Specifically, the hot water pipe 3 includes a venturi tube 301, and a suction pipe 302 is horizontally connected to the 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 the open state, the hot water passes through the venturi tube 301 and generates a suction force at the suction pipe 302, thereby circulating the water at the circulation connector 101 into the hot water pipe 3 for circulation.

[0032] The faucet seat 4 is equipped with a rotating plate 401, which is connected to a swing plate 103 on the circulation connector 101 via a pull rope 402. When the rotating plate 401 rotates, it drives the swing plate 103 to swing, causing the circulation connector 101 to connect with the water outlet of the faucet 1. The rotating plate 401 is equipped with a swing rod 403 that is driven when the switch lever 2 is moved towards the hot water side. Figure 1 and Figure 5 As shown, the switch lever 2 is equipped 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 towards... Figure 1 After swinging to the left in the indicated direction, it causes the swing rod 403 to move, causing the rotating plate 401 to rotate, thereby driving the swing plate 103 to swing and connecting the water outlet of the faucet 1 to the hot water circulation pipe 5.

[0033] The faucet seat 4 is provided with a limiting block 404 that restricts the rotation of the rotating plate 401 to the other side, such as Figure 5 As shown, the rotating plate 401 can only rotate to the left. When it rotates to the right, it is restricted and pushed against by the limiting block 404. That is, when the switch lever 2 is moved towards the cold water direction, the rotating plate 401 cannot be triggered. At this time, the circulation connector 101 is also misaligned with the outlet of the faucet 1, so that the cold water can be discharged normally from the faucet 1.

[0034] The faucet 1 is equipped with several guide connecting plates 104 for positioning the pull rope 402 and the circulation pipe 5, such as 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 sequentially passed through the above-mentioned guide connecting plate 104 and then fixedly connected to the outer edge of the rotating plate 401, so that the rotating plate 401 can drive the pull rope 402 to move; a return spring 105 is provided between the circulation joint 101 and the positioning plate 102.

[0035] A pin 106, which cooperates with the swing plate 103, is slidably mounted on the positioning plate 102. The upper end of the pin 106 is a spherical rod, and the lower end passes through the upper wall of the positioning plate 102 and is placed in the movable cavity 108 within the positioning plate 102. Figure 4 As shown, the movable cavity 108 is provided with an arc-shaped elastic sheet 109. The two ends of the elastic sheet 109 are fixedly clamped on the two side walls of the movable cavity 108, and the arc-shaped protrusion is connected to the lower end of the pin 106. The lower end of the pin 106 is clamped on the elastic sheet 109 through an annular groove.

[0036] A pin sleeve 107 is rotatably mounted on the swing plate 103; the pin sleeve 107 has a pin hole 112 that mates with the pin rod 106; the pull rope 402 passes through the upper end of the pin sleeve 107; the positioning plate 102 has a pull rope guide plate 113 that mates with the pull rope 402; when the swing plate 103 swings, it squeezes the upper end of the pin rod 106, causing the elastic sheet 109 to deform and compress. Then, when the pin rod 106 and the small hole 112 on the pin sleeve 107 are coaxial, the elastic sheet 109 returns to its original position, pushing the pin rod 106 upward, thus locking the swing plate 103 in this position, which achieves locking when the faucet 1 outlet is connected to the circulation connector 101.

[0037] The elastic sheet 109 is a bimetallic sheet. A guide rod 110 is provided at one end of the elastic sheet 109 near 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 passes through the wall of the faucet 1 and is placed inside the water outlet of the faucet 1. The guide rod 110 is a temperature-conducting rod, which can quickly conduct temperature to the elastic sheet 109. When the water in the outlet is warm, the guide rod 110 can conduct temperature to the elastic sheet 109, causing the elastic sheet 109 to deform. Figure 4 The arc protrusion shown deforms downwards in the opposite direction, causing the pin 106 to slide downwards, unlocking the lock between the swing plate 103 and the positioning plate 102. At this time, the circulation connector 101 is reset by the return spring 105, and the faucet 1 can be opened to dispense warm water, allowing the user to use it immediately.

[0038] The bottom of the movable cavity 108 is provided with a contact switch 111 that cooperates with the deformed elastic sheet 109. The contact switch 111 is electrically connected to the solenoid valve 303. The solenoid valve 303 is a one-way solenoid valve, and its flow direction is from the circulation pipe 5 to the suction pipe 302. When the contact switch 111 is triggered, the solenoid valve 303 can be closed, thus blocking the circuit between the circulation pipe 5 and the suction pipe 302. That is, when the circulation connector 101 is reset and moved to one side of the faucet 1, the circuit of the circulation pipe 5 is blocked, so that the circulation connector 101 will not leak water.

[0039] The method of using a mobile home water flow adaptive circulation device as described above:

[0040] S1: Initially, the outlet of the circulation connector 101 and the faucet 1 are misaligned. When hot water is needed, the operator uses the switch lever 2 to move it towards the hot water direction. Figure 1 Move to the left as shown;

[0041] S2: The magnet 201 on the switch lever 2 attracts the swing arm 403, thereby driving the rotating plate 401 to rotate a certain angle. Then, the switch lever 2 can be moved again to disengage it from the swing arm 403.

[0042] S3: While rotating plate 401 rotates at a certain angle, pull rope 402 pulls swing plate 103 to rotate circulation joint 101 at a certain angle, so that circulation joint 101 connects with faucet 1. At this time, pin rod 106 is inserted into pin hole 112, so that swing plate 103 and positioning plate 102 are relatively fixed.

[0043] S4: Hot water flows into the faucet seat 4 through the hot water pipe. Cold water in the pipe enters the faucet 1 and then enters the circulation pipe 5. At this time, the Venturi tube 301 draws the cold water in the circulation pipe 5 into the Venturi tube 301 due to the suction force of the hot water flow. This process continues until the water temperature at the outlet of the faucet 1 reaches a certain temperature.

[0044] S5: When the water temperature at the outlet reaches the standard, the guide rod 110 triggers the elastic deformation of the elastic sheet 109, allowing the guide rod 110 to conduct the temperature to the elastic sheet 109, causing the elastic sheet 109 to deform. Figure 4 The arc protrusion shown deforms downwards in the opposite direction, causing the pin 106 to slide downwards, unlocking the lock between the swing plate 103 and the positioning plate 102. At this time, the circulation connector 101 is reset by the return spring 105, and the faucet 1 can be opened to dispense warm water, allowing the user to use it immediately.
