[0002] Household hot water pipes are usually equipped with valves to control the on / off state and flow rate of hot water; these are typically knob valves.

[0003] Children or adults unfamiliar with electrical appliances may turn the knob out of curiosity, which may not only cause accidental hot water leakage, but also cause unnecessary waste of water resources and increase the economic burden on users. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a household hot water energy-saving control device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A household hot water energy-saving control device includes a connector with connection ports on both sides, a connecting pipe fixedly connected between the connection ports, a fixing bracket fixedly connected to the outer walls of both sides of the connector, a bidirectional threaded rod movably connected between the two fixing brackets and penetrating the interior of the connecting pipe, two sliders movably connected to the outer side of the bidirectional threaded rod, a baffle fixedly connected to the bottom of each slider, a clearance groove on both sides of the connector, the baffle passing through the clearance groove, a fixing ring fixedly connected to the inner circumference of the connector, a sliding groove inside the fixing ring, and the baffle slidingly connected to the corresponding sliding groove, and a pin assembly for restricting the movement of the sliders on the connector.

[0006] As a further embodiment of this utility model, the pin assembly includes two locking blocks, which are respectively welded to the top of two sliders. Magnetic plates are fixedly connected to both outer walls of the connector. Two positioning posts are fixedly connected to the bottom of the magnetic plates. An arc-shaped plate is movably connected between the two positioning posts. Connecting plates are fixedly connected between the first and last ends of the two arc-shaped plates. Multiple slots are provided at the bottom of the connecting plates, and the locking blocks are inserted into the corresponding slots.

[0007] As a further embodiment of this utility model, a stop block is fixedly connected to the bottom end of the positioning post, and a tension spring is sleeved on the outer side of the positioning post, with the two ends of the tension spring being fixed to the stop block and the arc-shaped plate respectively.

[0008] As a further embodiment of this invention, the diameter of the stop block is larger than the diameter of the positioning post, and the arc-shaped plate can be attracted and contacted with the magnetic plate located on the same side.

[0009] As a further embodiment of this utility model, a guide rod is fixedly connected to the fixing frame, and the guide rod is fixed to the outer wall of the joint, and the slider is slidably connected to the guide rod.

[0010] As a further embodiment of this utility model, both ends of the bidirectional threaded rod pass through the fixing frame and are fixedly connected with knobs.

[0017] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0018] Reference Figures 1-3 A household hot water energy-saving control device includes a connector 5, with connection ports on both sides of the connector 5. A connecting pipe 17 is welded between the connection ports. Fixing brackets 2 are welded to the outer walls of both sides of the connector 5. A bidirectional threaded rod 13 is rotatably connected between the two fixing brackets 2, and the bidirectional threaded rod 13 passes through the interior of the connecting pipe 17. Two sliders 12 are threadedly connected to the outer side of the bidirectional threaded rod 13. A baffle 1 is welded to the bottom of each slider 12. A clearance groove is provided on both sides of the connector 5, and the baffle 1 passes through the clearance groove. A fixing bracket is welded to the inner circumference of the connector 5. The bottom of the fixed ring 16 contacts the baffle 1. When the two baffles 1 contact and completely cover the circular space of the fixed ring 16, the joint 5 is closed. The fixed ring 16 has a sliding groove 11 inside, and the baffle 1 is slidably connected to the sliding groove 11 at the corresponding position. The sliding groove 11 is connected to the clearance groove at the adjacent position. Rotating the bidirectional threaded rod 13 causes the slider 12 to move to both sides, so that the baffle 1 slides along the sliding groove 11. At this time, the distance between the two baffles 1 gradually increases, thereby realizing the adjustment of the opening size of the joint 5.

[0019] In particular, the connector 5 is provided with a pin assembly to restrict the movement of the slider 12. The pin assembly includes two locking blocks 15, which are respectively welded to the top of the two sliders 12. Magnetic plates 6 are welded to both outer walls of the connector 5. Two positioning posts 8 are fixed to the bottom of the magnetic plates 6 by bolts. An arc-shaped plate 7 is slidably connected between the two positioning posts 8. Connecting plates 4 are fixed between the first and last ends of the two arc-shaped plates 7 by bolts. Multiple slots 14 are opened at the bottom of the connecting plates 4, and the locking blocks 15 are inserted into the corresponding slots 14. The bottom of the positioning posts 8... A stop block 10 is welded to the end of the positioning post 8. A tension spring 9 is sleeved on the outside of the positioning post 8, and the two ends of the tension spring 9 are fixed to the stop block 10 and the arc plate 7 respectively. Pulling the arc plate 7 upward causes it to slide upward along the positioning post 8, and the tension spring 9 extends until the arc plate 7 contacts the magnetic plate 6, so that the magnetic plate 6 attracts and fixes the arc plate 7. At the same time, the movement of the arc plate 7 causes the connecting plate 4 to move upward, thereby separating the locking block 15 from the locking groove 14. At this time, the slider 12 is no longer restricted. The diameter of the stop block 10 is larger than the diameter of the positioning post 8, and the arc plate 7 can attract and contact the magnetic plate 6 located on the same side.

[0020] It should be noted that after adjustment, when the arc plate 7 is released, under the action of the tension spring 9, the arc plate 7 slides downward, so that the slot 14 re-engages with the corresponding block 15, thereby restricting the movement of the slider 12 and fixing the size of the opening of the fixed joint 5. The guide rod 3 is fixed on the fixed frame 2 by bolts, and the guide rod 3 is fixed to the outer wall of the joint 5. The slider 12 is slidably connected to the guide rod 3. The guide rod 3 can guide the slider 12 and prevent the slider 12 from tilting during movement. Both ends of the bidirectional threaded rod 13 pass through the fixed frame 2 and are welded with knobs. When the block 15 is inserted into the slot 14, the magnetic force of the magnetic plate 6 will not attract the arc plate 7.

[0021] Working principle: When it is necessary to open the connector 5 or adjust the size of the opening of the connector 5, first pull the arc plate 7 upward so that it slides upward along the positioning post 8 and the tension spring 9 extends until the arc plate 7 and the magnetic plate 6 come into contact, so that the magnetic plate 6 attracts and fixes the arc plate 7. At the same time, the movement of the arc plate 7 causes the connecting plate 4 to move upward, thereby separating the locking block 15 from the locking groove 14. At this time, the slider 12 loses its restriction. Rotating the bidirectional threaded rod 13 causes the slider 12 to move to both sides along the guide rod 3, thereby causing the baffle 1 to slide along the slide groove 11. At this time, the distance between the two baffles 1 gradually increases, thus adjusting the size of the opening of the joint 5. To fully open connector 5, adjust the position of baffle 1 so that baffle 1 no longer obstructs the circular space of fixing ring 16.

[0022] After adjustment, release the arc plate 7. Under the action of the tension spring 9, the arc plate 7 slides downward, allowing the slot 14 to re-engage with the corresponding block 15, thereby restricting the movement of the slider 12 and fixing the size of the opening of the connector 5.
