Description

Technical Field

[0001] This utility model belongs to the field of sanitary ware technology, and in particular relates to a double-valve anti-splash urinal. Background Technology

[0002] Sensor-operated urinals operate with a pre-flush and a post-flush. The pre-flush is a brief rinse before use, primarily to wet the inner wall of the urinal and form a water film. This prevents urine from directly contacting the ceramic surface and avoids dirt adhesion. The post-flush, on the other hand, is a longer rinse after use to thoroughly remove any urine residue.

[0003] The pre-rinse typically lasts about 3 seconds, and the subsequent rinse lasts about 8 seconds. This design saves approximately 70% of water consumption. Although there are two rinses, the total water consumption for the pre-rinse and subsequent rinses is far lower than that of a single long rinse or multiple large-volume rinses. The entire rinsing process is automatic, requiring no manual intervention and is completed by sensors, effectively preventing cross-contamination of bacteria and viruses.

[0004] The normal operating pressure for urinals is 0.05~0.1MPa. Due to water pressure fluctuations; excessively high design water pressure; and increased water pressure by maintenance providers, especially in stations and shopping malls, to reduce manual cleaning and ensure thorough flushing, water mist or droplets may splash onto the user during pre-flushing, severely impacting the user experience and even posing safety and hygiene hazards, as well as the potential for disease transmission. Utility Model Content

[0005] In view of the defects or deficiencies in the existing technology, this utility model provides a dual-valve anti-splash urinal, which can achieve different water pressures for pre-flush and post-flush, avoiding water mist or droplets from splashing onto the human body due to excessive water pressure during pre-flush, thus improving the user experience and reducing safety and hygiene hazards.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An embodiment of this utility model provides a dual-valve anti-splash urinal, including a urinal with a water outlet on the inner wall of the urinal. The water outlet is connected to a tap water pipe through a flushing pipe. The flushing pipe includes a first branch pipe and a second branch pipe, which are arranged in parallel. A first valve is provided on the first branch pipe, and a second valve is provided on the second branch pipe. Both the first valve and the second valve are regulating valves, which can regulate the water pressure in the first branch pipe and the second branch pipe.

[0007] Furthermore, the flushing pipe also includes a water inlet pipe, one end of which is connected to the tap water pipe via a tee, and the other end of which is connected to the first branch pipe and the second branch pipe via a tee.

[0008] Furthermore, the ends of the first and second branch pipes furthest from the inlet pipe are connected to the outlet pipe via a tee, and the end of the outlet pipe furthest from the first and second branch pipes is connected to the outlet.

[0009] Furthermore, the water flow pressure in the first branch pipe is 0.01~0.05MPa, and the water flow pressure in the second branch pipe is 0.1~0.2MPa.

[0010] Furthermore, both the first valve and the second valve are located inside a control box, which is situated above the urinal.

[0011] Furthermore, the urinal is also equipped with a controller and an infrared sensor, and the first valve, the second valve, and the infrared sensor are all electrically connected to the controller.

[0012] Furthermore, the infrared sensor is a reflective infrared photoelectric sensor, and the detection end of the infrared sensor faces the front of the urinal.

[0013] Furthermore, the water outlet is provided with two outlets, namely a wetting outlet and a rinsing outlet, wherein the wetting outlet is connected to the first branch pipe and the rinsing outlet is connected to the second branch pipe.

[0014] Furthermore, the wetting port consists of multiple pinholes arranged side by side on the upper part of the inner wall of the urinal, located at the upper edge of the main impact area of ​​urine, and the flushing port is located behind the top edge of the inner wall during urination.

[0015] Furthermore, the urinal is provided with a drain outlet at the bottom, which is connected to a sewage pipe via a drain pipe.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model features a first branch pipe and a second branch pipe connected in parallel. The two ends of the first and second branch pipes are respectively connected to a tap water pipe and a urinal outlet. The first branch pipe is equipped with a first valve, and the second branch pipe is equipped with a second valve. Both the first and second valves are regulating valves, which can adjust the water pressure in the first and second branch pipes. This allows for different water pressures between pre-flush and post-flush, preventing excessive water pressure during pre-flush from splashing water mist or droplets onto the body, thus improving the user experience and reducing safety and hygiene hazards.

[0017] 2. This utility model features two water outlets: a wetting outlet and a flushing outlet. The wetting outlet is connected to a first branch pipe, and the flushing outlet is connected to a second branch pipe. The wetting outlet consists of multiple pinholes arranged side-by-side on the upper part of the urinal's inner wall, located at the upper edge of the main urine impact area. Water from the first branch pipe flows out through the wetting outlet and then flows downwards along the inner wall of the urinal, covering the core area where urine residue easily accumulates, forming a protective water film to prevent urine residue from adhering to the dry ceramic surface. The flushing outlet is located behind the top edge of the urinal's inner wall. Water from the second branch pipe flows out through the flushing outlet and then flushes downwards along the inner wall of the urinal at a set angle. The water flow naturally and evenly covers the entire inner wall of the urinal from the top, ensuring a thorough cleaning. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] A typical embodiment of this utility model is as follows: Figure 1 As shown, a double-valve anti-splash urinal includes a urinal 1, with an outlet 2 on the top of the inner wall of the urinal 1. The outlet 2 is connected to a tap water pipe 3 through a flushing pipe. Water from the tap water pipe 3 flows out from the outlet 2 through the flushing pipe to flush the inner wall of the urinal 1.

[0021] Furthermore, the flushing pipe includes an inlet pipe 4, one end of which is connected to a tap water pipe 3 via a tee, and the end of the inlet pipe 4 away from the tap water pipe 3 is connected to a first branch pipe 5 and a second branch pipe 6 via a tee. The first branch pipe 5 and the second branch pipe 6 are arranged in parallel. The ends of the first branch pipe 5 and the second branch pipe 6 away from the inlet pipe 4 are connected to an outlet pipe 7 via a tee. The end of the outlet pipe 7 away from the first branch pipe 5 and the second branch pipe 6 is connected to an outlet 2.

[0022] In this embodiment, the first branch pipe 5 is equipped with a first valve 8, and the second branch pipe 6 is equipped with a second valve 9. Both the first valve 8 and the second valve 9 are regulating valves. In this embodiment, the regulating valve is a common regulating valve on the market, which can achieve continuous and precise flow and pressure control. The water in the tap water pipe 3 passes through the first branch pipe 5 and the second branch pipe 6 respectively, and is adjusted to different pressure water flows through the first valve 8 and the second valve 9, thereby wetting and flushing the inner wall of the urinal 1.

[0023] Specifically, after the water in the tap water pipe 3 enters the first branch pipe 5, it is adjusted by the first valve 8 to a water pressure of 0.01~0.05MPa to wet the inner wall of the urinal 1. After the water in the tap water pipe 3 enters the second branch pipe 6, it is adjusted by the second valve 9 to a water pressure of 0.1~0.2MPa to flush the inner wall of the urinal 1.

[0024] Furthermore, both the first valve 8 and the second valve 9 are located inside the control box 10, thereby protecting the first valve 8 and the second valve 9. The control box 10 is located above the urinal 1. The control box 10 is also equipped with a controller and an infrared sensor 11. In this embodiment, the controller is a microcontroller. The first valve 8, the second valve 9 and the infrared sensor 11 are all electrically connected to the controller. The controller can control the operation of the first valve 8 and the second valve 9. The infrared sensor 11 is a reflective infrared photoelectric sensor. The detection end of the infrared sensor 11 faces the front of the urinal 1 and is used to detect whether someone is approaching.

[0025] It is known that the first valve 8, the second valve 9, the infrared sensor 11, and the controller are all powered by mains electricity.

[0026] When the infrared sensor 11 detects a person approaching, it sends a signal to the controller. The controller determines and controls the opening of the first valve 8 according to the preset program. Water in the tap water pipe 3 flows through the inlet pipe 4, the first branch pipe 5, and the outlet pipe 7 in sequence, and finally flows out from the outlet 2, forming a water film on the inner wall of the urinal 1. This pre-wets the inner wall of the urinal 1 and prevents urine residue from adhering to the dry ceramic surface. The first valve 8 is opened for a set time and then closed to avoid wasting water resources.

[0027] When the infrared sensor 11 detects that a person has left, the infrared sensor 11 sends a signal to the controller. The controller judges and controls the second valve 9 to open according to the preset program. The water in the tap water pipe 3 passes through the inlet pipe 4, the second branch pipe 6 and the outlet pipe 7 in sequence, and finally flows out from the outlet 2, thereby flushing the inner wall of the urinal 1 and filling the drain outlet 12 with waste. The second valve 9 closes after the set time to avoid water waste.

[0028] The urinal 1 has a drain outlet 12 at the bottom, and the drain outlet 12 is connected to the sewage pipe through the drain pipe 13. The sewage in the urinal 1 flows into the sewage pipe from the drain outlet 12.

[0029] In other implementations, such as Figure 2 As shown, the urinal 1 is provided with two water outlets 2, namely a wetting outlet 201 and a flushing outlet 202. The wetting outlet 201 is connected to the first branch pipe 5 and is used to wet the inner wall of the urinal 1. The flushing outlet 202 is connected to the second branch pipe 6 and is used to flush the inner wall of the urinal 1.

[0030] Specifically, the wetting port 201 consists of multiple pinholes arranged side-by-side on the upper part of the inner wall of the urinal 1, located at the upper edge of the main impact area of ​​urine. After the water in the first branch pipe 5 flows out of the wetting port 201, the water flows downward along the inner wall of the urinal 1, covering the core area where urine residue is easily retained, forming a protective water film to prevent urine residue from adhering to the dry ceramic surface. The flushing port 202 is located behind the top edge of the inner wall of the urinal 1. After the water in the second branch pipe 6 flows out of the flushing port 202, it flushes downward along the inner wall of the urinal 1 at a set angle. The water flow naturally and evenly covers the entire inner wall of the urinal 1 from the top, and finally flushes the waste into the drain port 12.

[0031] By setting up a first branch pipe and a second branch pipe, which are connected in parallel, and connecting the first branch pipe to the tap water pipe and the urinal outlet at both ends, the first branch pipe is equipped with a first valve and the second branch pipe is equipped with a second valve. Both valves are regulating valves, which can adjust the water pressure in the first and second branch pipes. This allows for different water pressures between pre-flush and post-flush, preventing excessive water pressure during pre-flush from splashing water mist or droplets onto the body, thus improving the user experience and reducing safety and hygiene hazards.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
