Technical Field
[0001] This utility model relates to the field of flow controllers, and in particular to an indoor anti-leakage and anti-pipe burst flow controller. Background Technology
[0002] With the increasing popularity of smart homes and people's rising demands for quality of life, indoor water safety is receiving more and more attention. Indoor leak and burst prevention flow controllers, as crucial devices for ensuring household water safety, can monitor water flow in real time and take timely measures in case of leaks or burst pipes, preventing property damage and water waste. They play a key role in household water system management.
[0003] Currently, the common method for connecting leak-proof and burst-pipe flow controllers to pipes involves setting internal and external threads on the pipe and joint respectively. The threads are then tightly fixed together using their interlocking action. This connection method is based on the meshing characteristics of mechanical threads. The pipe and joint are tightened manually or with tools to make the threads interlock and form a physical connection.
[0004] Existing anti-leakage and pipe burst flow controllers use threaded connections, which require repeated tightening with tools. This not only consumes a lot of time and manpower, but also easily damages the threads during operation. Once the threads are damaged, the connection's firmness is greatly reduced. Moreover, since manual operation makes it difficult to ensure that the tightening degree is completely consistent each time, some connection points may not be sealed properly, affecting the tightness of the connection. Therefore, an indoor anti-leakage and pipe burst flow controller is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an indoor anti-leakage and anti-burst pipe flow controller, which aims to improve the existing technology that requires repeated tightening of threaded connections, which consumes a lot of time and manpower, and is prone to thread damage or inconsistent tightening, affecting the tightness of the connection.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An indoor anti-leakage and pipe bursting flow controller includes a housing, a connector fixedly connected inside the housing, a protective shell fixedly connected to the upper surface of the housing, a control component disposed inside the protective shell, a fixing component disposed on the side wall of the connector, a sealing component disposed on the side wall of the connector, and a pipe disposed on the side wall of the connector.

[0013] As a further description of the above technical solution:
[0014] The control component includes a flow sensor, the sidewall of which is fixedly connected to the upper surface of the housing. A solenoid valve is fixedly connected to the upper surface of the housing. A control chip is fixedly connected inside the protective housing.

[0022] The second mounting ring has an internal mounting groove, the side wall of the O-ring is slidably connected to the inside of the mounting groove, and the side wall of the compression ring is attached to the side wall of the O-ring.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, by aligning the second mounting ring with the first mounting ring, the positioning rod is inserted into the second mounting ring for initial positioning. Then, pulling the pull ring causes the insertion rod to slide within the mounting sleeve, compressing the first spring. After rotating the rotating plate by a certain angle, the pull ring is released, and the first spring returns to its original position, pushing the insertion rod into the rotating plate, thereby fixing the first mounting ring and the second mounting ring together.

The side wall of mounting ring 2 (10) rotates... The moving connection includes a rotating plate 17, which engages with the insertion rod 13. Rotation of the plate allows for engagement or disengagement with the insertion rod 13, thus enabling the fixing and disassembly of the pipe 8.

The positioning rod 11, in conjunction with the mounting ring 10, performs a positioning movement, achieving rapid and accurate installation of the pipe 8. The insertion rod 13 is slidably connected to the inside of the rotating plate 17.

[0038] The control components include a flow sensor 4, which is fixedly connected to the upper surface of the housing 1. The flow sensor 4 is used to monitor the water flow rate through the connector 2 and pipe 8 in real time. A solenoid valve 6 is fixedly connected to the upper surface of the housing 1.

The control chip 5 is used to receive the electrical signals transmitted by the flow sensor 4, analyze and process the flow data, and send control commands to the solenoid valve 6 according to the analysis results. The control chip 5 is electrically connected to the flow sensor 4 and the solenoid valve 6. The three work together to monitor, analyze and control the water flow rate, achieving the effect of automatically preventing water leakage and pipe bursts. A display screen 7 is fixedly connected to the upper surface of the protective housing 3. The display screen 7 is electrically connected to the control chip 5.

[0039] Reference Figure 6 and Figure 7The sealing assembly includes an O-ring 22, which is made of rubber and is used to fill the gaps between mounting ring 19 and mounting ring 20, as well as the connection between pipe 8 and connector 2, thus providing a seal and effectively preventing water leakage from the connection. The sidewall of the O-ring 22 is fitted inside the mounting ring 20. A fixing sleeve 18 is fixedly connected inside the mounting ring 19, and a compression ring 19 is slidably connected inside the fixing sleeve 18. The compression ring 19 applies pressure to the O-ring 22 after the mounting rings 19 and 20 are fixed, causing it to deform and enhancing the sealing effect. A limit ring 20 is fixedly connected to the sidewall of the compression ring 19, limiting the sliding range of the compression ring 19 within the fixing sleeve 18 and preventing the compression ring 19 from sliding excessively and detaching from the fixing sleeve 18. The sidewall of the limit ring 20 is slidably connected inside the fixing sleeve 18, and a... Spring 21, one end of which is fixedly connected to the side wall of the compression ring 19, works with the compression ring 19 to compress the O-ring 22, thereby fully deforming it to enhance the sealing effect. The mounting ring 10 has an internal mounting groove 23 for positioning the O-ring 22, ensuring it is accurately installed in the correct position for sealing with the compression ring 19. The side wall of the O-ring 22 is slidably connected to the inside of the mounting groove 23, and the side wall of the compression ring 19 fits against the side wall of the O-ring 22. The mounting groove 23, O-ring 22, compression ring 19, and spring 21 work together. After the pipe 8 is fixedly connected to the connector 2, spring 21 pushes the compression ring 19 to compress the O-ring 22, causing it to fully deform within the mounting groove 23 and tightly fill the connection gap, achieving a highly efficient seal and preventing water leakage.
[0040] Working principle: When connecting pipe 8 to connector 2, first align mounting ring 2 10 with mounting ring 1 9, inserting positioning rod 11 into mounting ring 2 10 to ensure accurate alignment. Then, pull ring 14, causing insertion rod 13 to slide inside mounting sleeve 12. At this time, fixing ring 15 compresses spring 16. Next, rotate rotating plate 17 to fit against mounting sleeve 12, then release pull ring 14. Spring 16 returns to its original position, pushing insertion rod 13 into rotating plate 17, thus fixing mounting ring 1 9 and mounting ring 2 10 together, ultimately connecting pipe 8 to connector 2. When mounting ring 1 9 and mounting ring 2 10 are fixed together, spring 21 in fixing sleeve 18 inside mounting ring 1 9 pushes compression ring 19. Compression ring 19 slides within fixing sleeve 18, its sidewall adhering to the sidewall of O-ring seal 22 and applying pressure. Because the O-ring 22 is elastic, it deforms when compressed, tightly filling the gaps between the mounting ring 19 and the mounting ring 20, as well as the connection between the pipe 8 and the connector 2, thus effectively preventing water leakage and achieving a good sealing effect. During equipment operation, the flow sensor 4 monitors the water flow through the connector 2 and the pipe 8 in real time and converts the flow data into an electrical signal, which is then transmitted to the control chip 5 inside the protective housing 3. The control chip 5 analyzes and processes the flow data. When an abnormal flow is detected, such as exceeding the preset normal flow range, and it is determined that a leak or pipe burst has occurred, the control chip 5 sends an electrical signal to the solenoid valve 6 to control the solenoid valve 6 to close, cutting off the water flow and preventing further losses caused by leaks or pipe bursts. At the same time, the control chip 5 can also transmit relevant flow data and equipment operating status information to the display screen 7 for display, allowing users to understand the operation of the flow controller in real time.
