Description
Technical Field
[0001] This utility model relates to the technical field of water purifier leak prevention protection devices, specifically a water purifier leak prevention protection device. Background Technology
[0002] Leakage is a common safety hazard during the use of water purifiers, which may cause cabinets to become damp and floors to be damaged. Therefore, leak protection devices have become an important part of ensuring the safe operation of water purifiers.
[0003] When using existing water purifier leak protection devices,
[0004] (1) The response speed of water leakage blocking is relatively slow, and it often takes a period of time after the water leakage occurs to achieve water cut-off, which can easily cause a certain degree of loss;
[0005] (2) The fixing to the water purifier is not secure enough. It is easy to loosen during long-term use or when the pipeline vibrates, which affects the leak prevention effect.
[0006] To address the above problems, this utility model provides a water purifier leak-proof protection device. Utility Model Content
[0007] The purpose of this utility model is to provide a water purifier anti-leakage protection device. This utility model can quickly stop leakage and fix it firmly to the water purifier, thereby solving the problems of slow leakage prevention and unstable fixation of existing devices.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a water purifier anti-leakage protection device, comprising a fixed ring and a quick anti-leakage component, wherein the quick anti-leakage component is fixedly connected to the inner wall of the fixed ring, and the quick anti-leakage component includes a protective column fixedly connected to the inner wall of the fixed ring.
[0009] A connecting column is fixedly connected to the inner wall of the protective column, a hydraulic box is fixedly connected to the inner bottom wall of the connecting column, a hydraulic rod body is fixedly connected inside the hydraulic box, a leak-proof pipe is connected through the top of the connecting column, a sliding column is fixedly connected to the top of the hydraulic rod body, and the sliding column is slidably connected to the inner wall of the leak-proof pipe.
[0010] Furthermore, the bottom ends of both sides of the leak-proof pipe are connected to transmission pipes, and the upper and lower ends of the protective column are connected to connecting pipes. This achieves the function of the transmission pipes diverting and transmitting water in the leak-proof pipes, and the connecting pipes connecting the protective column to external pipes to ensure normal water flow.
[0011] Furthermore, an interface pipe is connected through the surface of the connecting pipe, and an adjusting ring is threaded onto the surface of the interface pipe. This allows the interface pipe to be easily connected to external pipes of different specifications. The adjusting ring can be rotated to adjust the tightness of the interface pipe, thereby enhancing the sealing of the connection and preventing water leakage at the interface.
[0012] Furthermore, a fixing component is fixedly connected to the surface of the fixing ring. The fixing component includes a fixing box fixedly connected to the surface of the fixing ring. The fixing box provides an installation carrier for other parts of the fixing component, realizes a stable connection between the fixing component and the fixing ring, and provides a foundation for fixing the device.
[0013] Furthermore, a motor box is fixedly connected to one side of the fixed box, and a servo motor is fixedly connected inside the motor box. This achieves the purpose of protecting the servo motor from external collisions or moisture, and the servo motor providing power for the operation of the fixed component.
[0014] Furthermore, a transmission rod is fixedly connected to the output end of the servo motor, and a positive and negative threaded rod is fixedly connected to one end of the transmission rod. This enables the transmission rod to transmit the power of the servo motor to the positive and negative threaded rod, allowing the positive and negative threaded rod to rotate smoothly and providing power for the movement of the sliding block.
[0015] Furthermore, one end of the positive and negative threaded rod is rotatably connected to the inner wall of the fixed box, and both sides of the surface of the positive and negative threaded rod are threaded with sliding blocks. The sliding blocks are slidably connected to the inner wall of the fixed box, and the surface of the sliding blocks is fixedly connected with clamping plates. When the positive and negative threaded rod rotates, the sliding blocks on both sides slide on the inner wall of the fixed box and drive the clamping plates to move closer or further apart, thereby achieving a stable clamping of the water purifier and enhancing the stability of the connection between the device and the water purifier.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] This utility model provides a water purifier leak-proof protection device.
[0018] (1) By setting up a quick leak-proof component, when the personnel operate the device, if a leak is detected, the hydraulic rod body will quickly drive the sliding column to rise in the leak-proof pipe to quickly seal the leak-proof pipe, block the water flow in time, and reduce the loss caused by the leak. The transmission pipe and connecting pipe will ensure the smooth flow of water under normal circumstances.
[0019] (2) By setting the fixed components, when the personnel operate the device, the servo motor is started, and the positive and negative threaded rods are driven to rotate through the transmission rod, so that the sliding block drives the clamping plate to clamp and fix the water purifier, ensuring that the device will not loosen during use and ensuring the stable performance of the leak-proof function.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] To solve the problem of how to effectively position and adjust the technology, such as Figure 1-5 As shown, the following preferred technical solutions are provided:
[0028] A water purifier anti-leakage protection device includes a fixed ring 1 and a quick anti-leakage component 2. The quick anti-leakage component 2 is fixedly connected to the inner wall of the fixed ring 1. When the device is operated by personnel and a leak is detected, the hydraulic rod body 204 quickly drives the sliding column 206 to rise in the anti-leakage pipe 205, thereby quickly sealing the anti-leakage pipe 205, blocking the water flow in time, and reducing the loss caused by the leak. The transmission pipe 207 and the connecting pipe 208 ensure the smooth flow of water under normal conditions. The quick anti-leakage component 2 includes a protective column 201 fixedly connected to the inner wall of the fixed ring 1.
[0029] A connecting column 202 is fixedly connected to the inner wall of the protective column 201. A hydraulic box 203 is fixedly connected to the inner bottom wall of the connecting column 202. A hydraulic rod body 204 is fixedly connected inside the hydraulic box 203. A leak-proof pipe 205 is connected through the top of the connecting column 202. A sliding column 206 is fixedly connected to the top of the hydraulic rod body 204. The sliding column 206 is slidably connected to the inner wall of the leak-proof pipe 205.
[0030] Specifically, when operating the device, the operator must first connect the device's connecting pipe 208 to the water purifier's inlet and outlet pipes via the interface pipe 209, and rotate the adjusting ring 210 to ensure a sealed interface. Then, the servo motor 303 of the fixing component 3 is activated, causing the clamping plate 307 to clamp the water purifier's pipes and complete the fixing process. During daily use, if the detection system triggers a leak signal, the hydraulic rod body 204 will automatically push the sliding column 206 to seal the leak-proof pipe 205. The operator must then check for leaks, reset the device, and then rotate the adjusting ring 210 to restart the water circuit.
[0031] Furthermore, such as Figure 2 As shown, the following preferred technical solutions are provided:
[0032] Both ends of the leak-proof pipe 205 are connected to the bottom of the transmission pipe 207, and both ends of the protective column 201 are connected to the connecting pipe 208. The purpose of this design is that the transmission pipe 207 can divert the water flow in the leak-proof pipe 205 to the subsequent pipe of the water purifier to ensure normal water circulation. The connecting pipe 208 serves as the connection port between the device and the external water circuit, realizing the input and output of water flow, and also forming a closed space with the leak-proof pipe 205 to prevent water leakage when sealing leaks.
[0033] Furthermore, such as Figure 2 As shown, the following preferred technical solutions are provided:
[0034] The surface of the connecting pipe 208 is connected to the interface pipe 209, and the surface of the interface pipe 209 is threaded with an adjusting ring 210. The purpose of this design is that the interface pipe 209 can be adapted to water purifier pipes of different diameters, improving the versatility of the device. The adjusting ring 210 can enhance the sealing performance at the interface by adjusting the tightness of the thread, avoiding water leakage caused by connection gaps, and at the same time facilitating quick connection during installation and disassembly during maintenance.
[0035] Furthermore, such as Figure 4 As shown, the following preferred technical solutions are provided:
[0036] A fixing component 3 is fixedly connected to the surface of the fixing ring 1. The fixing component 3 includes a fixing box 301 fixedly connected to the surface of the fixing ring 1. The purpose of this design is that the fixing box 301 provides a closed installation space for the transmission structure of the fixing component 3 to prevent moisture from corroding the internal components. At the same time, through the rigid connection with the fixing ring 1, the clamping force is evenly transmitted to the whole device to ensure the stability of the fixing.
[0037] Furthermore, such as Figure 4 As shown, the following preferred technical solutions are provided:
[0038] A motor box 302 is fixedly connected to one side of the fixing box 301. A servo motor 303 is fixedly connected inside the motor box 302. The purpose of this design is that the motor box 302 is made of waterproof material, which can isolate water vapor and dust around the water purifier and protect the circuit components of the servo motor 303. The servo motor 303 can provide stable torque output, ensuring that the movement of the clamping plate 307 is precise and controllable, and avoiding fixing failure caused by being too loose or too tight.
[0039] Furthermore, such as Figure 4 As shown, the following preferred technical solutions are provided:
[0040] The output end of the servo motor 303 is fixedly connected to a transmission rod 304, and one end of the transmission rod 304 is fixedly connected to a positive and negative threaded rod 305. The purpose of this design is to efficiently transmit the rotational motion of the servo motor 303 to the positive and negative threaded rod 305 through the transmission rod 304, and reduce power loss through rigid connection. The bidirectional thread design of the positive and negative threaded rod 305 can drive the sliding blocks 306 on both sides to move synchronously in opposite directions, so as to realize the symmetrical opening and closing of the clamping plate 307.
[0041] Furthermore, such as Figure 3 As shown, the following preferred technical solutions are provided:
[0042] One end of the threaded rod 305 is rotatably connected to the inner wall of the fixed box 301. Both sides of the surface of the threaded rod 305 are threaded with sliding blocks 306. The sliding blocks 306 are slidably connected to the inner wall of the fixed box 301. The surface of the sliding blocks 306 is fixedly connected with a clamping plate 307. The purpose of this design is to ensure the stable rotation of the threaded rod 305 and the fixed box 301. Under the threaded drive and the limit of the inner wall of the fixed box 301, the sliding blocks 306 drive the clamping plate 307 to accurately clamp the water purifier pipe. The symmetrical clamping force counteracts the reaction force generated by the water flow impact and prevents the device from shifting.
[0043] Working principle: When using the device, first connect the water purifier's water circuit through the interface pipe 209 and adjusting ring 210. Start the servo motor 303, which drives the positive and negative threaded rods 305 to rotate via the transmission rod 304, causing the sliding block 306 to drive the clamping plate 307 to clamp the pipe and complete the fixation. Under normal working conditions, water flows through the connecting pipe 208, protective column 201, connecting column 202, leak-proof pipe 205, and transmission pipe 207. When a leak is detected, the hydraulic rod body 204 quickly pushes the sliding column 206 to rise inside the leak-proof pipe 205, blocking the water circuit. At the same time, the transmission pipe 207 and connecting pipe 208 cooperate to form a closed space to prevent the leakage from spreading. The fixing component 3 continuously clamps to ensure the stability of the device and avoids the leak-proof effect being affected by loosening.
