Description

Technical Field

[0001] This utility model relates to the field of sanitary ware technology, specifically a water-saving urinal. Background Technology

[0002] A urinal is a bathroom fixture designed specifically for men. It is typically installed in public restrooms and home bathrooms, fixed vertically against the wall. Its shape is often funnel-shaped or columnar, with a drain at the bottom that connects to the sewer pipe. Its main function is to facilitate men's standing urination. Compared to traditional toilets, it reduces urine splashing, saves flushing water, and is convenient to use and easy to clean and maintain. It is a common facility that improves the efficiency and hygiene of the bathroom. It is mostly made of ceramic, and the surface is often glazed to enhance smoothness and stain resistance.

[0003] Most urinals currently rely on infrared sensing technology to detect moving objects in front of them. When non-users (such as pedestrians or cleaning staff) pass quickly within the sensing range, the sensor may mistakenly identify them as users who have finished using the urinal, thus triggering the flushing process. This false triggering not only wastes water resources but also generates unnecessary noise due to frequent flushing. Especially in densely populated areas such as shopping malls and train stations, this affects the efficiency and energy conservation of the equipment. Therefore, we propose a water-saving urinal. Utility Model Content

[0004] The purpose of this invention is to provide a water-saving urinal that automatically activates flushing when urine sprays onto the sensor plate. This avoids ineffective flushing due to sensor misjudgment or inactivity, significantly reducing water waste and improving ease of use. Furthermore, it avoids noise interference caused by frequent accidental flushing in high-traffic areas. The avoidance of accidental flushing also reduces unnecessary wear and tear on mechanical parts, extending the equipment's lifespan. This invention solves the problem that current urinals often rely on infrared sensing technology to detect moving objects. When non-users (such as pedestrians or cleaning staff) pass quickly within the sensing range, the sensor may mistakenly identify them as users who have finished using the urinal, triggering the flushing process. This mis-triggering not only wastes water but also generates unnecessary noise due to frequent flushing, especially in densely populated areas such as shopping malls and train stations, affecting the equipment's efficiency and energy conservation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water-saving urinal, comprising a urinal body, wherein a trough is provided inside the urinal body, a water volume sensor is installed on the inner wall of the trough near the lower surface, a sensor is installed on the inner wall of the trough near the upper surface, a voice control module is installed on the lower surface of the sensor, a flushing outlet is provided on the lower surface of the sensor, and a dual-control switching valve is installed on one side of the upper surface of the urinal body, wherein the inlet end and outlet end of the dual-control switching valve are respectively connected to an inlet pipe and an outlet connecting pipe, and the outlet connecting pipe is connected to the flushing outlet.

[0006] Preferably, an external power supply box is installed inside the sensor.

[0007] Preferably, the sensor and the water level sensor are electrically connected via an inductive connection line.

[0008] Preferably, the end of the water inlet pipe is connected to a water inlet connector.

[0009] Preferably, the dual-control switching valve penetrates the upper surface of the urinal body, and the inlet pipe and outlet pipe are located inside the urinal body near the rear surface of the trough.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This utility model, by incorporating a urinal body, trough, sensor, voice control module, dual-control switching valve, and water volume sensor, achieves automatic flushing when urine sprays onto the sensor plate. This avoids ineffective flushing due to sensor misjudgment or inactivity, significantly reducing water waste and improving ease of use. Furthermore, it prevents noise interference caused by frequent accidental flushing in high-traffic areas. The avoidance of accidental flushing also reduces unnecessary wear and tear on mechanical parts, extending the equipment's lifespan. In practical applications, when… When the user stands and urinates into the urinal, the water volume sensor can capture the presence of liquid (urine) in the urinal in real time, with a detection accuracy of ±5ml, ensuring that even trace amounts of urine can be accurately identified. This detection signal is transmitted in real time to a high-precision sensor in the form of an electrical signal. After signal analysis and verification within 0.3 seconds, the sensor sends an opening command to the dual-control switching valve. At this time, the flushing water will flow sequentially through the inlet pipe, outlet connection pipe, dual-control switching valve, and flushing outlet into the urinal, efficiently completing the urine flushing and cleaning. Additionally, in special usage scenarios, when... To address the issue of users urinating very little, causing the water volume sensor to fail to detect the flow, or the sensor malfunctioning and misjudging the flow, a smart voice control module and a manual control interface have been added. The voice control module supports voice command recognition within a 1-3 meter range, recognizing preset commands (such as "start flushing" and "stop flushing") with an accuracy rate of over 98%, and is resistant to environmental noise (it can operate normally in environments with noise levels below 60 decibels). The manual control interface features a waterproof press-type design, allowing users to manually open and close the dual-control switching valve by pressing, further enhancing ease of use and reliability. Therefore, in public places with high foot traffic (such as shopping malls, office buildings, and stations), it effectively avoids the continuous noise caused by frequent accidental flushing of traditional sensor urinals (flushing noise can be reduced to below 55 decibels), improving the acoustic environment of public spaces. At the same time, the number of invalid starts of the dual-control switching valve is significantly reduced, which can significantly reduce the wear frequency of internal valve seals, springs, and other mechanical components, extending the service life of components, reducing equipment maintenance costs and replacement frequency, and achieving a dual improvement in economic and environmental benefits.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] like Figures 1-4 As shown, the present invention proposes a water-saving urinal, including a urinal body 1, with a trough 4 inside the urinal body 1. The trough 4 is shaped like a "J" in side cross-section and is used to hold urine excreted by a man when standing. At the same time, the bottom of the trough 4 is provided with a drain outlet and connected to a drain pipe. The urine inside the trough 4 is discharged into the sewer through the drain pipe. A water volume sensor 5 is installed on the inner wall of the trough 4 near the lower surface, and a sensor 2 is installed on the inner wall of the trough 4 near the upper surface. The sensor 2 and the water volume sensor 5 are electrically connected by an induction connection line 11. The water volume sensor 5 detects whether water is flowing inside the trough 4, and the detection signal is transmitted to the sensor 2.

[0019] A voice control module 7 is installed on the lower surface of sensor 2, and a flushing outlet 6 is provided on the lower surface of sensor 2. A dual-control switching valve 3 is installed on one side of the upper surface of the urinal body 1. The dual-control switching valve 3 is provided with a push-button manual control interface. Both the dual-control switching valve 3 and the voice control module 7 are electrically connected to sensor 2. The voice control module 7 sends a voice control signal to sensor 2, and sensor 2 controls the dual-control switching valve 3 to open through the voice control signal. At the same time, when the water volume sensor 5 detects water flowing inside the trough 4, sensor 2 will also control the dual-control switching valve 3 to open. The sensor 2 is equipped with a... An external power supply box 8 is installed. The power supply battery inside the external power supply box 8 powers the sensor 2, the voice control module 7, the water volume sensor 5, and the dual-control conversion valve 3. The inlet and outlet ends of the dual-control conversion valve 3 are respectively connected to the inlet pipe 9 and the outlet connection pipe 12, and the outlet connection pipe 12 is connected to the flushing outlet 6. The end of the inlet pipe 9 is connected to the inlet connector 10, and the inlet pipe 9 is connected to the water supply pipe through the inlet connector 10. The dual-control conversion valve 3 penetrates the upper surface of the urinal body 1, and the inlet pipe 9 and the outlet connection pipe 12 are located inside the urinal body 1 near the rear surface of the trough 4.

[0020] In practical use, when a user stands and urinates into the trough 4, the water volume sensor 5 can capture the presence signal of liquid (urine) in the trough 4 in real time, with a detection accuracy of ±5ml, ensuring that even trace amounts of urine can be accurately identified. This detection signal is transmitted in real time to the high-precision sensor 2 in the form of an electrical signal. After signal analysis and verification within 0.3 seconds, the sensor 2 sends an opening command to the dual-control switching valve 3. At this time, the flushing water will flow into the trough 4 through the inlet pipe 9, the outlet connection pipe 12, the dual-control switching valve 3, and the flushing outlet 6, efficiently completing the urine flushing and cleaning. At the same time, in special usage scenarios, when the user's urine volume is very small, causing the water volume sensor 5 to fail to detect it, or when the water volume sensor 5 misjudges due to a temporary malfunction, a smart voice control module 7 and a manual control interface are specially added: the voice control module 7 supports a range of 1-3 meters. The voice command recognition system can recognize preset commands (such as "start flushing" and "stop flushing") with an accuracy rate of over 98%, and it is also resistant to environmental noise (it can work normally in environments with noise levels below 60 decibels). The manual control interface adopts a waterproof push-button design, allowing users to manually open and close the dual-control switching valve 3 by pressing, further improving ease of use and reliability. Therefore, in public places with high pedestrian traffic (such as shopping malls, office buildings, and stations), it can effectively avoid the continuous noise caused by frequent accidental flushing of traditional sensor urinals (flushing noise can be reduced to below 55 decibels), improving the acoustic environment of public spaces. At the same time, the number of invalid starts of the dual-control switching valve 3 is greatly reduced, which can significantly reduce the wear frequency of internal valve seals, springs, and other mechanical parts, extend the service life of components, reduce equipment maintenance costs and replacement frequency, and achieve a dual improvement in economic and environmental benefits.
