Detailed Embodiment

[0019] As Figures 1 - 6 shown, this embodiment provides an energy-saving reflux device, including a reflux liquid storage tank 1, a striker assembly 2, a leather cup 3, a push-pull mechanism 4, a liquid inlet pipe 5, a pressure valve 6, a liquid outlet pipe 7, a connecting pipe 8 and a check valve 9. One end of the reflux liquid storage tank 1 is provided with a first water port and a second water port. The reflux liquid storage tank 1 is used for storing the returned water. The first water port is mainly used to return the residual tap water in the liquid outlet pipe 7 to the reflux liquid storage tank 1, and the second water port is mainly used to return the returned water in the reflux liquid storage tank 1 to the liquid outlet pipe 7.

[0020] As Figure 2As shown, the striker assembly 2 is installed at the first water inlet of the reflux liquid storage tank 1. The striker assembly 2 is movable to control the opening and closing of the pressure valve 6. The leather cup 3 is movably arranged inside the reflux liquid storage tank 1. The leather cup 3 is provided with an elastic restoring member. The leather cup 3 is provided with a pushing head 10 for movably contacting the striker assembly 2. The pushing head 10 is a hexagonal large screw. One end of the pushing and pulling mechanism 4 extends into the reflux liquid storage tank 1 and is connected to the leather cup 3. The pushing and pulling mechanism 4 is driven by an external force. When the pushing and pulling mechanism 4 applies an external force to the leather cup 3 or the elastic restoring member drives the leather cup 3 to move upward, a negative pressure is generated inside the reflux liquid storage tank 1, and the residual tap water in the liquid outlet pipe 7 flows back into the reflux liquid storage tank 1. When the pushing and pulling mechanism 4 drives the leather cup 3 to move downward, the leather cup 3 presses out the backflow water in the reflux liquid storage tank 1. When the pushing and pulling mechanism 4 drives the leather cup 3 to move downward to the bottommost position, the pushing head 10 of the leather cup 3 contacts the striker assembly 2, causing the striker assembly 2 to press the pressure valve 6 to open the pressure valve 6. After the striker assembly 2 is separated from the pressure valve 6, the pressure valve 6 automatically closes.

[0021] As Figure 3 shown, one end of the liquid inlet pipe 5 is communicated with the first water inlet of the reflux liquid storage tank 1. One end of the liquid outlet pipe 7 is communicated with the liquid inlet pipe 5. The pressure valve 6 is arranged between the liquid inlet pipe 5 and the liquid outlet pipe 7, and the opening and closing of the pressure valve 6 is controlled by the striker assembly 2. One end of the connecting pipe 8 is communicated with the liquid outlet pipe 7, and the other end of the connecting pipe 8 is communicated with the second water inlet of the reflux liquid storage tank 1. The check valve 9 is arranged between the connecting pipe 8 and the reflux liquid storage tank 1. The elastic restoring member includes a return spring 24. A fixing buckle 25 for fixing the return spring 24 is arranged inside the reflux liquid storage tank 1, and the return spring 24 can be used to drive the leather cup 3 to automatically return to its original position.

[0022] During normal water use, the pushing and pulling mechanism 4 applies an external force to the leather cup 3 to move the leather cup 3 downward to the bottommost position. The striker assembly 2 presses the pressure valve 6 to open the pressure valve 6. The liquid inlet pipe 5 is communicated with the liquid outlet pipe 7, and the water in the liquid inlet pipe 5 flows into the liquid outlet pipe 7 through the pressure valve 6. After the water use is completed, when the pushing and pulling mechanism 4 applies an external force to the leather cup 3 to move the leather cup 3 upward, after the striker assembly 2 loses the pressure of the pushing head 10, the pressure valve 6 automatically closes. When the leather cup 3 moves upward, a negative pressure is generated inside the reflux liquid storage tank 1, and the residual tap water in the liquid outlet pipe 7 flows back into the reflux liquid storage tank 1 through the striker assembly 2. When water needs to be used again, the pushing and pulling mechanism 4 applies an external force to the leather cup 3 to move the leather cup 3 downward. The leather cup 3 presses the backflow water in the reflux liquid storage tank 1 into the liquid outlet pipe 7 through the check valve 9. Then the pushing head 10 of the leather cup 3 contacts the striker assembly 2, causing the striker assembly 2 to press the pressure valve 6 to open the pressure valve 6.

[0023] The present invention adopts hydrodynamic design, reduces water resource waste and energy waste during use through an energy-saving reflux device, does not consume electricity, basically realizes automatic operation, is convenient for users to use at all times, can help residents in northern regions or regions with lower temperatures in winter solve the problem that outdoor water pipes are prone to freezing in winter, and can effectively avoid waste of water resources.

[0024] As Figure 4 shown, in this embodiment, the striker assembly 2 includes a striker 11 and a striker mounting seat 12. The striker mounting seat 12 is installed at the first water inlet of the reflux liquid storage tank 1. A through hole is provided on the striker mounting seat 12. The striker 11 is slidably arranged in the through hole, and a flow gap for liquid flow is left between the striker 11 and the through hole. A limiting mechanism for restricting the striker 11 from sliding out of the striker mounting seat 12 is provided on the striker 11. The first water inlet is provided with internal threads, and the striker mounting seat 12 is provided with external threads. In order to prevent water leakage, the striker mounting seat 12 is provided with a sealing ring. The inner diameter of the through hole on the striker mounting seat 12 is larger than the outer diameter of the striker 11, so that the striker 11 can slide along the through hole, and the residual tap water in the liquid outlet pipe 7 can enter the reflux liquid storage tank 1 through the flow gap. When the striker 11 slides along the through hole, the striker 11 is limited by the limiting mechanism to prevent the striker 11 from detaching from the striker mounting seat 12.

[0025] Specifically, the limiting mechanism includes an upper limiting member and a lower limiting member. The upper limiting member and the lower limiting member are both arranged on the striker 11, and the upper limiting member and the lower limiting member are respectively located at both ends of the through hole. Preferably, the upper limiting member includes an upper sealing flap 13. The upper sealing flap 13 is slidably sleeved on the striker 11. An upper end head is provided at one end of the striker 11 close to the upper sealing flap 13, and the upper end head is in movable contact with the push head 10. The lower limiting member includes a lower limiting seat 14. The lower limiting seat 14 is fixedly arranged on the striker 11. A lower pointed head is provided at one end of the striker 11 close to the lower limiting seat 14, and the lower pointed head contacts the pressure valve 6 and controls the opening and closing of the pressure valve 6.

[0026] Among them, the inner diameter of the through hole is larger than the outer diameter of the ejector pin 11, and the inner diameter of the through hole is smaller than the outer diameter of the upper sealing washer 13, so that the upper sealing washer 13 covers the through hole to prevent water leakage. In the initial state, the pressure valve 6 is in the open state, the liquid inlet pipe 5 and the liquid outlet pipe 7 are communicated to supply water normally. After the water is used up, when an external force is applied to the leather cup 3 by the push-pull mechanism 4 or the elastic restoring member drives the leather cup 3 to move upward, after the ejector pin assembly 2 loses the pressure of the push head 10, the pressure valve 6 automatically closes. When the leather cup 3 moves upward, a negative pressure is generated inside the return liquid storage tank 1, and the residual tap water in the liquid outlet pipe 7 flows back to the return liquid storage tank 1 through the circulation gap. After the reflux is completed, the upper sealing washer 13 slides along the ejector pin 11 under the action of gravity and covers the through hole, so that the residual tap water remains in the return liquid storage tank 1; when water is needed again, the push-pull mechanism 4 applies an external force to the leather cup 3 to make the leather cup 3 move downward. The leather cup 3 presses the return water in the return liquid storage tank 1 into the liquid outlet pipe 7 through the check valve 9. After the water in the return liquid storage tank 1 is basically discharged, the push head 10 of the leather cup 3 contacts the ejector pin 11, so that the ejector pin 11 presses the pressure valve 6 to open the pressure valve 6, realizing the smooth water supply function.

[0027] As Figure 1 shown, in a specific embodiment, the push-pull mechanism 4 includes a push-pull rod 15 and a guide sleeve 16. Both the push-pull rod 15 and the guide sleeve 16 are square structures. The guide sleeve 16 is installed outside the return liquid storage tank 1. The push-pull rod 15 is slidably matched with the guide sleeve 16. One end of the push-pull rod 15 extends into the return liquid storage tank 1 and is connected to the push head 10. A push-pull handle 17 is provided at the end of the push-pull rod 15 away from the push head 10. By driving the push-pull rod 15 to slide along the guide sleeve 16 through the push-pull handle 17, the leather cup 3 is controlled to move up and down inside the return liquid storage tank 1.

[0028] Preferably, the push-pull rod 15 is provided with a locking mechanism. As Figure 6 shown, among them, the locking mechanism includes a locking sleeve 18, a locking rod 19 and a locking handle 20. The locking sleeve 18 is slidably sleeved outside the guide sleeve 16, and a locking bolt 21 is provided on the locking sleeve 18; after the locking sleeve 18 slides along the guide sleeve 16 to a suitable position, the locking sleeve 18 is fixed by the locking bolt 21. The locking rod 19 is rotatably installed on the locking sleeve 18, and a torsion spring 29 is provided between the locking rod 19 and the locking sleeve 18. A locking buckle 22 is provided on the locking rod 19. As Figure 5As shown in the figure, the push rod 15 is provided with a card slot 23 adapted to the locking buckle 22, and the locking handle 20 is connected to the locking rod 19. The locking rod 19 is L-shaped. Under the action of the torsion spring 29, the locking buckle 22 of the locking rod 19 is inserted into the card slot 23 of the push rod 15 to lock the push rod 15, so that the pressure valve 6 remains open for a long time. When it is necessary to close the pressure valve 6, press the locking handle 20 to separate the locking buckle 22 from the card slot 23, and then move the push rod 15. The locking rod 19 can automatically return to its original position under the action of the torsion spring 29.

[0029] In order to facilitate the maintenance of the reflux storage tank 1, the reflux storage tank 1 includes an upper shell 26 and a lower shell 27. An adjustable clamp 28 is provided between the upper shell 26 and the lower shell 27. The adjustable clamp 28 is used to connect the upper shell 26 and the lower shell 27 to form a sealed tank for storing the backflow water. The lower shell 27 is connected with a protective cover 30. The protective cover is used to protect the liquid inlet pipe 5 and the liquid outlet pipe 7. One ends of the liquid inlet pipe 5 and the liquid outlet pipe 7 both extend outside the protective cover 30.

[0030] The present invention provides an energy-saving reflux device. The liquid inlet pipe 5, the liquid outlet pipe 7 and the connecting pipe 8 are welded to form an F-shaped structure. The liquid outlet pipe 7 is connected to the reflux storage tank 1 through a check valve 9. A pressure valve 6 is arranged inside the liquid inlet pipe 5. The pressure valve 6 is controlled by a striker 11. The reflux storage tank 1 is circular and is fixed in the middle by an adjustable clamp 28. The upper shell 26 of the reflux storage tank 1 is welded to the guide sleeve 16. There is a circular leather cup 3 inside the upper shell 26. The leather cup 3 is connected to the push rod 15. Two convex circular iron cups are arranged at the connection of the leather cup 3 and the push rod 15 and are fixed by screws. The push rod 15 is designed with a card slot 23, and the locking rod 19 is designed with a locking buckle 22. The locking buckle 22 is in the shape of an eagle's beak and is inserted into the card slot 23 of the push rod 15 to fix the push rod 15.

[0031] The working process of this energy-saving reflux device includes: 1. Tap water enters from the liquid inlet pipe 5. If the push-pull handle 17 is pressed, the leather cup 3 in the reflux storage tank 1 will follow the push rod 15 downwards. The hexagonal large screw inside the leather cup 3 will push against the striker 11, and the striker 11 will push open the pressure valve 6 in the liquid inlet pipe 5. The water flows out from the liquid inlet pipe 5 to the liquid outlet pipe 7. At this time, the water supply starts. At the same time, the locking buckle 22 will automatically latch into the card slot 23 of the push rod 15 to fix the push rod 15. 2. Press the locking buckle 22, and the locking buckle 22 will separate from the card slot 23. The push rod 15 and the leather cup 3 will be pushed up and returned to their original positions by the return spring 24 inside the reflux storage tank 1. At this time, the striker 11 retreats, the pressure valve 6 closes, and the water supply stops immediately. After the water supply stops, the stagnant water in the liquid outlet pipe 7 will flow back to the reflux storage tank 1 through the flow gap at the striker 11.

[0032] 3. When the next program starts, press the push-pull handle 17, and the retained water in the reflux liquid storage tank 1 will flow out of the check valve 9 into the liquid outlet pipe 7 under the influence of the pressure of the leather cup 3. When the push-pull handle 17 is pressed to a certain extent, the striker 11 knocks open the pressure valve 6, and the water in the liquid inlet pipe 5 enters the liquid outlet pipe 7, and enters the next use process.

[0033] Compared with the prior art, the present invention has the following advantages: 1. Reasonable design, combining fluid mechanics model and algorithm to achieve adaptive flow channel design. After multiple design adjustments, the model was optimized based on fluid mechanics simulation experiments to design a flow channel model that is suitable for different application scenarios. In the process, fluid mechanics technology was used to achieve the optimal design of pipeline curvature.

[0034] 2. The structure is simple and light, easy to disassemble, repair and maintain, with low failure rate and easy operation, which broadens the application of the reflux device.

[0035] 3. Durable materials. The leather cup 3 is made of edible grade silicone with a service life of not less than 3 years. The reflux liquid storage tank 1 has an anti-rust coating, and the pressure valve 6 and the check valve 9 are made of copper to improve durability.
