Description

Technical Field

[0001] This utility model relates to the field of intelligent sports venue technology, and more specifically to an induction-type shower water-saving device. Background Technology

[0002] In the functional support system and high-frequency service scenarios of smart sports venues, shower devices, as core supporting facilities for post-competition recovery and daily fitness, have been deeply integrated into key areas such as athlete training areas, public fitness service areas, event guest rest areas, and staff logistics areas. Their core value lies in providing a stable and gentle water flow to people after high-intensity exercise, quickly relieving muscle fatigue and meeting cleaning needs. At the same time, they need to adapt to the "pulsating" water usage characteristics of the venue. Currently, the mainstream shower device in smart sports venues is the intelligent water-controlled shower device. In addition, intelligent shower heads with constant temperature function and multiple water output modes are also common. They are mainly composed of water control machine, flow meter, solenoid valve and management software. Users can start the shower by inserting an IC card, scanning a code or using a smart bracelet. The water control system monitors the water flow in real time through the flow meter and deducts fees according to the set billing standard. When the shower ends, the user operates again to turn it off, and the solenoid valve quickly shuts off the water flow.

[0003] However, in actual use, after showering and closing the shower valve, a common problem gradually emerges: some water remains inside the pipe connected to the top showerhead. Under the combined effect of residual pressure and gravity, this residual water slowly drips or even overflows from the showerhead outlet. After the valve is closed, the water in the pipe loses its power source, but under the combined effect of residual water pressure and gravity, it gradually flows towards the relatively higher top showerhead, eventually forming a continuous dripping or small flow of water for a period of time. After each shower, all the residual water in the pipe is discharged through the showerhead. This water is not necessary for the user's actual use and is a typical example of ineffective water consumption. If it accumulates over a long period of time, especially in high-frequency use scenarios such as smart sports stadiums, it will cause a large waste of water resources. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an induction shower water-saving device to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: an induction shower water-saving device, including a water inlet pipe, a connecting cylinder fixedly installed at the output end of the water inlet pipe, a water outlet pipe threadedly installed at the output end of the connecting cylinder, and a top shower head fixedly installed at the output end of the water outlet pipe. An electric telescopic rod is fixedly installed inside the connecting cylinder. The connecting cylinder has a sealing groove, a connecting groove, and a cylindrical groove. A sealing plate is fixedly connected to the output end of the electric telescopic rod. The outer surface of the sealing plate is longitudinally and slidably connected to the inside of the sealing groove. The inside of the sealing groove is connected to the inside of the cylindrical groove through the connecting groove. A positioning ring is fixedly connected to the inner wall of the cylindrical groove. A pressure sensor is fixedly installed on the surface of the positioning ring. A water-saving component is installed inside the sealing groove.

[0006] Furthermore, the water-saving component includes a fixed plate fixedly connected to the inner wall of the cylindrical groove, a connecting rod slidably connected longitudinally at the inner center of the positioning ring, a limit plate fixedly connected to the end of the connecting rod, a spring movably sleeved on the outer surface of the connecting rod, a sliding plate fixedly connected to the top of the connecting rod, a sealing rod fixedly connected to the upper surface of the fixed plate, and the sliding plate slidably and sealingly connected to the outer surface of the sealing rod.

[0007] Furthermore, the pressure sensor controls the extension and retraction of the electric telescopic rod via a controller, a sealing ring is fixedly installed on the outer surface of the sealing plate, threads are provided at both ends of the inner wall of the cylindrical groove, and the water outlet pipe and water inlet pipe are both fixedly connected to the inside of the cylindrical groove by threaded sealing.

[0008] Furthermore, an insertion hole is provided at the center of the surface of the fixed plate, and water inlet holes are provided in a ring-shaped row at equal intervals on the surface of the fixed plate, and the outer surface of the connecting rod is inserted into the interior of the insertion hole.

[0009] Furthermore, a sealing sleeve is fixedly installed on the outer surface of the sliding disc, and a water outlet hole matching the sealing rod is opened through the surface of the sliding disc. A rubber sleeve is fixedly connected to the inner wall of the water outlet hole, and the outer surface of the sealing rod is slidably connected to the inner wall of the rubber sleeve.

[0010] Furthermore, under normal conditions, the sliding disc slides towards the fixed disc due to the elasticity of the spring, and the sliding disc is longitudinally sealed and slidably connected to the inside of the cylindrical groove through a sealing sleeve.

[0011] Furthermore, a solenoid valve is fixedly installed on the surface of the water outlet pipe, and the output end of the solenoid valve extends into the interior of the water outlet pipe. A smart card water controller electrically connected to the solenoid valve is installed on the wall.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model solves the industry pain point of residual water dripping after the valve is closed in traditional shower devices by combining mechanical structure and sensor control. At the moment the water valve is closed, the water pressure inside the cylindrical groove drops sharply. The elastic potential energy of the spring drives the limiting plate to move the sliding plate downward through the connecting rod. When the sealing rod is accurately inserted into the water outlet hole of the sliding plate, a sealed space is quickly formed inside the cylindrical groove. As the sliding plate continues to move downward, a negative pressure is generated in the sealed space, which can actively draw the water remaining at the top of the water outlet pipe and inside the top shower head into the cylindrical groove for storage, avoiding the ineffective water consumption caused by the continuous dripping of residual water due to the residual pressure of the pipe and gravity in traditional devices.

[0014] 2. This utility model's water-saving device, on the one hand, achieves intelligent auxiliary adjustment of water flow interruption through the linkage control of a pressure sensor and an electric telescopic rod. When the water valve is opened, high-pressure water pushes the sliding plate upward and triggers the pressure sensor. The sensor drives the electric telescopic rod to extend through the controller, causing the sealing plate to move downward, ensuring stable water pressure below the cylindrical groove. This provides stable power for the water to flow through the gap between the fixed plate and the sliding plate and finally spray out from the shower head, avoiding the problem of fluctuating water flow caused by water pressure fluctuations. When the water valve is closed, the sliding plate moves downward and disengages from the pressure sensor. The sensor immediately feeds back to the controller to shorten the electric telescopic rod, reducing the water pressure below the cylindrical groove, creating favorable conditions for the sliding plate to quickly reset, and further reducing the time of residual water dripping.

[0015] 3. This utility model, by installing a solenoid valve on the water outlet pipe and connecting it to a smart card water controller, uses mechanical and sensor-based coordination to recover residual water when the valve is closed, stabilize water pressure when the valve is open, and also provides intelligent control of access rights and billing, further solving the problem of residual water dripping and wasting in traditional devices.

[0021] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0022] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0023] A sensor-operated shower water-saving device includes an inlet pipe 1, a connecting cylinder 4 fixedly installed at the output end of the inlet pipe 1, an outlet pipe 2 threadedly installed at the output end of the connecting cylinder 4, and a top shower head 3 fixedly installed at the output end of the outlet pipe 2. An electric telescopic rod 5 is fixedly installed inside the connecting cylinder 4. The connecting cylinder 4 has a sealing groove 6, a connecting groove 7, and a cylindrical groove 9. A sealing plate 8 is fixedly connected to the output end of the electric telescopic rod 5. The outer surface of the sealing plate 8 is longitudinally and slidably connected to the inside of the sealing groove 6. The inside of the sealing groove 6 is connected to the inside of the cylindrical groove 9 through the connecting groove 7. A positioning ring 11 is fixedly connected to the inner wall of the cylindrical groove 9. A pressure sensor 12 is fixedly installed on the surface of the positioning ring 11. A water-saving component 10 is installed inside the sealing groove 6.

[0024] In this implementation scheme, the inlet pipe 1 is responsible for a stable water supply, the outlet pipe 2 ensures smooth water flow to the top shower head 3, and the connecting cylinder 4 integrates core control and adjustment components such as the electric telescopic rod 5 and the sealing groove 6. The electric telescopic rod 5 can drive the sealing plate 8 to slide in the sealing groove 6. The sealing groove 6 is connected to the cylindrical groove 9 through the connecting groove 7, which can adjust the water pressure in the cylindrical groove 9. All components work together to ensure a stable water flow output during normal showering and to efficiently handle residual water after the water valve is closed, thus achieving the dual goals of water saving and stable user experience.

[0025] Specifically, the water-saving component 10 includes a fixed plate 101 fixedly connected to the inner wall of the cylindrical groove 9, a connecting rod 102 slidably connected longitudinally at the inner center of the positioning ring 11, a limit plate 103 fixedly connected to the end of the connecting rod 102, a spring 104 movably sleeved on the outer surface of the connecting rod 102, a sliding plate 106 fixedly connected to the top of the connecting rod 102, a sealing rod 105 fixedly connected to the upper surface of the fixed plate 101, and the sliding plate 106 slidably and sealingly connected to the outer surface of the sealing rod 105.

[0026] In this embodiment, the fixed plate 101 provides a stable installation base for the connecting rod 102 and the sealing rod 105, and its water inlet 1012 allows water to flow through in an orderly manner; the connecting rod 102 connects the limiting plate 103 and the sliding plate 106, and can transmit the elastic force of the spring 104 to drive the sliding plate 106 to reset; the limiting plate 103 can prevent the connecting rod 102 from coming out of the positioning ring 11, ensuring the integrity of the component structure; the spring 104 pushes the sliding plate 106 close to the fixed plate 101 under normal conditions, and can quickly drive the sliding plate 106 to reset when the water valve is closed; the sealing rod 105 can be inserted into the water outlet 1062 when the sliding plate 106 resets, forming a sealed space; the sliding plate 106 slides sealed with the cylindrical groove 9 through the sealing sleeve 1061, and works with the sealing rod 105 to realize water flow interruption control and negative pressure formation, effectively recovering residual water, reducing ineffective water consumption, and at the same time assisting in regulating water flow and improving the water-saving efficiency of the device.

[0027] Specifically, the pressure sensor 12 controls the extension and retraction of the electric telescopic rod 5 through the controller, a sealing ring is fixedly installed on the outer surface of the sealing plate 8, threads are provided at both ends of the inner wall of the cylindrical groove 9, and the water outlet pipe 2 and the water inlet pipe 1 are both fixedly connected to the inside of the cylindrical groove 9 through threaded sealing.

[0028] In this implementation scheme, the pressure sensor 12, controller, and electric telescopic rod 5 form an intelligent linkage system. After the pressure sensor 12 detects the pressure signal of the sliding disc 106, it precisely controls the extension and retraction of the electric telescopic rod 5 through the controller, thereby driving the sealing plate 8 to slide in the sealing groove 6, adjusting the water pressure in the cylindrical groove 9, ensuring stable water flow during showering, and helping the sliding disc 106 to quickly reset when the water valve is closed. The sealing ring of the sealing plate 8 enhances the sealing performance of the sealing groove 6, preventing water leakage and ensuring the water pressure regulation effect. The threaded structure at both ends of the inner wall of the cylindrical groove 9 allows the inlet pipe 1 and outlet pipe 2 to be fixedly connected by a threaded seal, which not only facilitates installation but also effectively prevents water leakage at the connection, improves the overall sealing performance and stability of the device, ensures orderly water flow within the device, and reduces water waste and malfunctions caused by connection problems.

[0029] Specifically, a socket 1011 is provided at the center of the surface of the fixed plate 101, and water inlet holes 1012 are provided in a ring at equal intervals on the surface of the fixed plate 101. The outer surface of the connecting rod 102 is inserted into the interior of the socket 1011.

[0030] In this embodiment, the insertion hole 1011 of the fixed plate 101 provides a precise and stable installation channel for the connecting rod 102, allowing the connecting rod 102 to slide longitudinally within it. This ensures the stability and accuracy of the connecting rod 102 when it drives the sliding plate 106 to move, and avoids the sliding plate 106 and sealing rod 105 from being affected by the offset of the connecting rod 102. The water inlet holes 1012, which are equidistantly arranged in a ring array, allow water to flow evenly and orderly through the fixed plate 101 into the columnar groove 9, avoiding water pressure fluctuations caused by concentrated water flow impact. At the same time, it ensures sufficient water flow and guarantees the water output effect during showering, which not only improves the comfort of use, but also lays the foundation for stable water delivery in the future.

[0031] Specifically, a sealing sleeve 1061 is fixedly installed on the outer surface of the sliding disc 106, and a water outlet hole 1062 matching the sealing rod 105 is opened through the surface of the sliding disc 106. A rubber sleeve is fixedly connected to the inner wall of the water outlet hole 1062, and the outer surface of the sealing rod 105 is slidably connected to the inner wall of the rubber sleeve.

[0032] In this embodiment, the sealing sleeve 1061 of the sliding disc 106 enhances its sealing performance with the inner wall of the cylindrical groove 9, preventing water leakage between the sliding disc 106 and the cylindrical groove 9, ensuring the effect of water pressure regulation and negative pressure formation, and reducing water waste. The water outlet 1062 matches the sealing rod 105, and together with the rubber sleeve on the inner wall, a good seal can be formed when the sealing rod 105 is inserted. After the water valve is closed, a sealed space can be quickly built to generate negative pressure to recover residual water. The rubber sleeve can also reduce the frictional wear between the sealing rod 105 and the water outlet 1062, extend the service life of the components, and further improve the sealing performance, avoiding residual water leakage due to poor sealing, and ensuring water-saving effect.

[0033] Specifically, under normal conditions, the elasticity of the spring 104 causes the sliding disk 106 to slide towards the fixed disk 101. The sliding disk 106 is longitudinally sealed and slidably connected to the inside of the cylindrical groove 9 through the sealing sleeve 1061.

[0034] In this implementation scheme, under normal conditions, the elastic force of the spring 104 causes the sliding disc 106 to approach the fixed disc 101, preparing for the rapid reset of the sliding disc 106 after the water valve is closed, shortening the response time for residual water recovery and reducing the duration of residual water dripping. The sliding disc 106 slides longitudinally in a sealed manner with the cylindrical groove 9 through the sealing sleeve 1061, ensuring the smooth movement of the sliding disc 106 and avoiding jamming that could affect the operation of the device. On the other hand, it ensures the sealing of different areas within the cylindrical groove 9, allowing water pressure regulation to be precisely applied to the corresponding areas. At the same time, it smoothly forms negative pressure after the water valve is closed, efficiently recovering residual water in the water outlet pipe 2 and the top shower head 3, maximizing the water-saving goal.

[0035] Specifically, a solenoid valve 13 is fixedly installed on the surface of the water outlet pipe 2, and the output end of the solenoid valve 13 extends into the interior of the water outlet pipe 2. A smart card water controller 14, which is electrically connected to the solenoid valve 13, is installed on the wall.

[0036] In this implementation scheme, the solenoid valve 13 on the surface of the water outlet pipe 2 can precisely control the flow of water inside the water outlet pipe 2. Its output end extends into the inside of the water outlet pipe 2 and can directly act on the water flow channel. Compared with traditional manual valves, it has a faster response speed and can instantly cut off or open the water flow when the intelligent control signal is triggered, reducing invalid water flow caused by valve opening and closing delays. The smart card water controller 14 on the wall is electrically connected to the solenoid valve 13, which can realize on-demand billing and water use permission management. Users need to swipe a card to start the shower device. On the one hand, it can effectively prevent unauthorized personnel from using water resources at will and reduce waste in public places. On the other hand, the metered charging mechanism encourages users to actively develop water-saving habits and reduce the water consumption per shower. At the same time, the smart card water controller 14 can also record water use data, which makes it easier for managers to analyze the water use patterns in different areas and time periods. This provides data support for subsequent optimization of water supply schemes and further improvement of water-saving efficiency, achieving a dual water-saving effect of "precise control + intelligent management". It is especially suitable for high-frequency, high-flow water use scenarios such as smart sports stadiums.

[0037] The working principle and usage process of this utility model are as follows: When in use, after connecting the input end of the water inlet pipe 1 to the water valve, the water valve is opened. High-pressure water enters the bottom of the cylindrical groove 9 through the water inlet pipe 1 and enters the water inlet hole 1012. Due to the water pressure, the sliding plate 106 slides upward. When the sliding plate 106 slides upward, it drives the connecting rod 102 and the limiting plate 103 to slide upward. At this time, the spring 104 is in a compressed state. When the sliding plate 106 is separated from the sealing rod 105, the high-pressure water enters the upper part of the cylindrical groove 9 through the connection between the fixed plate 101 and the sliding plate 106, and then enters the top shower head 3 through the water outlet hole 1062. When the sliding plate 106 slides upward and is separated from the sealing rod 105, the upper surface of the sliding plate 106 will abut against the surface of the pressure sensor 12. After the pressure sensor 12 detects the pressure, it starts the electric telescopic rod 5 to extend through the controller, causing the sealing plate 8 to slide downward.

[0038] When the water valve is closed, the water pressure inside the cylindrical groove 9 drops instantly. Due to the elasticity of the spring 104, the limiting plate 103 drives the sliding plate 106 to slide downwards via the connecting rod 102. After the sealing rod 105 is inserted into the water outlet 1062, the upper part of the cylindrical groove 9 is sealed. Therefore, when the sliding plate 106 slides downwards, the upper part of the cylindrical groove 9 is under negative pressure, which can draw the water remaining at the top of the water outlet pipe 2 and the top shower head 3 into the cylindrical groove 9, avoiding the drawback of residual water seepage. In order to ensure that the sliding plate 106 slides downwards smoothly, at the moment the water valve is closed, the elasticity of the spring 104 causes the sliding plate 106 to slide downwards a certain distance and disengage from the pressure sensor 12. After the pressure sensor 12 is no longer under pressure, the controller starts the electric telescopic rod 5 to shorten and drive the sealing groove 6 to slide upwards. Therefore, the water pressure inside the cylindrical groove 9 drops, ensuring that the sliding plate 106 slides downwards more quickly and preventing more water from dripping from the top shower head 3.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
