Description

Technical Field

[0001] This application relates to the technical field of urinal waste disposal, and in particular to an intelligent water-saving and odor-proof urinal. Background Technology

[0002] Climate change has led to unstable precipitation patterns and frequent droughts and floods. Water conservation can enhance our ability to cope with droughts. The fundamental purpose of water conservation is to improve the rational use of water in cities, reduce the intake of fresh water and unnecessary discharge, improve the quality of drinking water for the people, and effectively protect the water resources environment on which we depend for survival. Urinals are simple in structure, aesthetically pleasing, and practical. They are used in public places such as hospitals, schools, hotels, and offices. With improvements in manufacturing technology, urinals are becoming increasingly popular. Besides public places, private households are also increasingly favoring urinals, thus the market prospects are very broad.

[0003] Urinals on the market are either wall-mounted or freestanding, consisting of a urinal body with a urinal trough on the front or side. The bottom of the urinal has a drain connector or drain valve. The rear or back side of the urinal body has a mounting groove, in which part of a drain bend is located. The first end of the drain bend connects to the bottom of the urinal trough, and the drain connector or drain valve connects to this first end. The second end of the drain bend connects to the building's main sewage pipe. After use, the nozzle at the top of the urinal sprays water, discharging urine and wastewater through the drain connector or drain valve into the drain bend, and then into the building's main sewage pipe.

[0004] However, existing urinals use flush valves or dedicated water supply, consuming an average of 3-5 liters of water. According to the national standard GB-2005, the standard model consumes 5 liters of water, while the water-saving model consumes 3 liters, and there are certain requirements for water supply pressure. Unstable water pressure can easily lead to incomplete flushing, failing to meet usage requirements. Excessive water pressure can increase water consumption and cause wastewater to splash out of the toilet bowl, making cleaning inconvenient and difficult. Utility Model Content

[0005] In order to reduce water consumption and improve the hygiene and cleanliness of urinals, this application provides an intelligent water-saving and odor-proof urinal.

[0006] This application provides a smart water-saving and odor-proof urinal, which adopts the following technical solution:

[0007] A smart water-saving and odor-proof urinal includes:

[0008] A signal acquisition device is disposed on the operating end face. The signal acquisition device is used to acquire the obstruction position in real time and generate a sensing signal based on the obstruction position and a preset distance.

[0009] A control start device is provided, which is connected to the signal acquisition device to receive the sensing signal and generate a switch start command based on the sensing signal. The control start device is also used to control the solenoid valve to open the flushing operation based on the switch start command.

[0010] A sealing and odor-proof mechanism is electrically connected to the control and start device to receive the switch start command, monitors the water pressure value in real time based on the switch start command, generates a drainage operation signal based on the water pressure value and a preset value, and sends the drainage operation signal to the control and start device.

[0011] The control start device receives the drainage operation signal and generates the switch closing command based on the drainage operation signal and the sensing signal, and controls the solenoid valve to close the flushing operation based on the switch closing command.

[0012] By adopting the above technical solution, the control start device is connected to the signal acquisition device to receive the sensing signal, and generates a switch start command based on the sensing signal. The control start device is also used to control the solenoid valve to open the flushing operation based on the switch start command. When the control start device receives the drainage operation signal and generates a switch close command based on the drainage operation signal and the sensing signal, it controls the solenoid valve to close the flushing operation based on the switch close command, thereby reducing water consumption. Furthermore, the sealing and odor-proof mechanism monitors the water pressure value in real time based on the switch start command, generates a drainage operation signal based on the water pressure value and a preset value, and sends the drainage operation signal to the control start device, thereby improving the hygiene and cleanliness of the urinal.

[0013] Preferably, it also includes a cleaning module, wherein the sealing and odor-proof mechanism is electrically connected to the control and start device, the control and start device generates a cleaning start signal based on the valve closing signal, and controls the cleaning module to spray cleaning agent onto the operating end face based on the cleaning start signal.

[0015] Preferably, the cleaning module includes a cleaning nozzle and a cleaning tank. The cleaning tank is located inside the urinal housing and is used to hold cleaning liquid. One end of the cleaning nozzle extends into the cleaning tank, and the other end is located at the water outlet on the operating end face.

[0016] Specifically, the control start device generates a cleaning start signal based on the valve closing signal, and controls the electronic valve to spray cleaning agent onto the operating end face based on the cleaning start signal.

[0017] By adopting the above technical solution, when the control start device generates a cleaning start signal based on the valve closing signal, and controls the electronic valve to spray cleaning agent onto the operating end face based on the cleaning start signal, the spraying of cleaning agent is started when the control start device closes the solenoid valve flushing switch, so that the cleaning agent is evenly sprayed on the operating end face under the flow of residual water, thereby improving the cleaning power of the entire operating end face.

[0018] Preferably, the sealing and odor-proof module includes a protective baffle, a water pressure sensor, and a drainage channel. The protective baffle has a drainage outlet in the middle, the drainage channel is hollowed out, and the water pressure sensor is located in the middle of the drainage channel. The upper end of the water pressure sensor is attached to the drainage outlet, and the lower end of the water pressure sensor is fixed to the drainage channel.

[0019] By adopting the above technical solution, the protective baffle and the water pressure sensing component work together to prevent sewage from entering the interior of the water pressure sensing component, thereby improving the service life of the water pressure sensing component. Then, the sewage is discharged through the hollow drainage channel, thus achieving the effect of 360-degree rapid sewage discharge from the operating end face.

[0020] Preferably, the water pressure sensing element includes a water pressure sensing end and a magnetic retractable rod fixed to the water pressure sensing end, and the water pressure sensing end covers the drain outlet;

[0021] When there is a preset water pressure at the bottom of the operating end face, the magnetic lifting rod will move away from the operating end face to open the drain outlet. When there is no preset water pressure at the bottom of the operating end face, the magnetic lifting rod will move closer to the drain outlet to close the drain outlet.

[0022] By adopting the above technical solution, when there is a preset water pressure at the bottom of the operating end face, the magnetic retractable rod will move away from the operating end face to open the drain outlet. When there is no preset water pressure at the bottom of the operating end face, the magnetic retractable rod will move closer to the drain outlet to close the drain outlet. This enables the urinal to open the drain outlet when there is water and close the drain outlet when there is no water, thus improving the urinal's odor prevention, insect control, and backflow prevention effects.

[0023] Preferably, the water pressure sensing end adopts a convex structure, and the lower end of the convex structure is attached to the lower end of the drain outlet.

[0029] The control start device is connected to the signal acquisition device to receive the sensing signal and generate a switch start command based on the sensing signal. The control start device is also used to control the solenoid valve to open the flushing operation based on the switch start command. When the control start device receives the drain operation signal and generates a switch close command based on the drain operation signal and the sensing signal, it controls the solenoid valve to close the flushing operation based on the switch close command, thereby reducing water consumption. In addition, the sealing and odor prevention mechanism monitors the water pressure value in real time based on the switch start command, generates a drain operation signal based on the water pressure value and a preset value, and sends the drain operation signal to the control start device, thereby improving the hygiene and cleanliness of the urinal.

[0059] It should be noted that the data transmission circuit 33 includes, but is not limited to, the above description, as long as it can achieve signal acquisition.

[0060] Reference Figure 8 and Figure 9 In another embodiment, the sealing and odor-proof mechanism 40 includes a protective baffle 41, a water pressure sensor 42, and drainage columns 43. The protective baffle 41 has a drainage outlet 411 in the middle. The drainage columns 43 are hollowed out, and there are multiple drainage columns 43. A drainage groove 431 is provided between adjacent drainage columns 43. The water pressure sensor 42 is located in the middle of the drainage columns 43. The upper end of the water pressure sensor 42 is in contact with the drainage outlet 411, and the lower end of the water pressure sensor 42 is fixed to the drainage column 43. The water pressure sensor 42 is connected to the operating end face 11 through a sealing ring. When there is water pressure at the bottom of the operating end face 11, the water pressure sensor 42 senses the water pressure and moves axially away from the drainage outlet 411, thereby allowing sewage to flow out along the drainage outlet 411 in the direction of movement of the water pressure sensor.

[0061] Figure 9 Figure c shows a front view of the sealing and odor-proof mechanism 40, while Figure 9 Figure d in the middle is Figure 9 The sectional view of Figure c. (Combined with...) Figure 9 The water pressure sensing element 42 includes a water pressure sensing end 421 and a magnetic retractable rod 422 fixed to the water pressure sensing end 421. The water pressure sensing end 421 covers the drain outlet 411. When there is a preset water pressure at the bottom of the operating end face 11, the magnetic retractable rod 422 will move away from the operating end face 11 to open the drain outlet 411. When there is no preset water pressure at the bottom of the operating end face 11, the magnetic retractable rod 422 will move closer to the drain outlet 411 to close the drain outlet 411.

[0062] It should be noted that the water pressure sensing element 42 includes a first magnet 424 and a second magnet 425. The first magnet 424 and the second magnet 425 are magnets of the same polarity. When there is no preset water pressure at the bottom of the operating end face 11, the magnetic lifting rod 422 will move along the axial direction of the magnetic lifting rod 422 towards the drain outlet 411 under the magnetic force of the repulsion between the magnets of the same polarity, so that the water pressure sensing end 421 covers the lower end of the drain outlet 411, thereby closing the sewage discharge of the drain outlet 411.

[0063] The water pressure sensing end 421 adopts a convex structure, and a protective plate 423 is provided at the lower end of the convex structure. The protective plate 423 is attached to the lower end of the drain outlet 411. The convex structure passes through the water outlet, and the protective plate 423 is attached to the lower end of the drain outlet 411, which can prevent residual water from flowing into the water pressure sensing element 42, prevent water loss to the interior of the water pressure sensing element 42, and improve the service life of the water pressure sensing element 42.

[0064] Reference Figure 1 and Figure 2 In another embodiment, the cleaning module 50, the sealing and odor-proof mechanism 40 are electrically connected to the control start device 30. When the solenoid valve closes the flushing, the control start device 30 generates a cleaning start signal and controls the cleaning module 50 to spray cleaning agent onto the operating end face 11 based on the cleaning start signal.

[0065] Specifically, the cleaning module 50 includes a cleaning nozzle 51 and a cleaning tank 52. The cleaning tank 52 is located inside the urinal housing 10 and is used to hold cleaning fluid. One end of the cleaning nozzle 51 extends into the cleaning tank 52, and the other end is located at the water outlet of the operating end face 11. The cleaning nozzle 51 uses an electronic valve, which is electrically connected to the control start module. The control start device 30 generates a cleaning start signal based on a valve closing signal and controls the electronic valve to spray cleaning fluid onto the operating end face 11 based on the cleaning start signal.

[0066] It should be noted that the position of the water outlet on the operating end face is not limited. Cleaning liquid and / or water can be added to the cleaning tank, and the operating end face 11 of the cavity 12 can be cleaned through the cleaning nozzle 51, thereby achieving a long-lasting cleaning effect.

[0067] Furthermore, the cleaning frequency of the operating end face can be set based on the number of people using the toilet. For example, it can be cleaned for every 5 people or every 10 people, thus achieving water conservation. The cleaning here includes flushing and cleaning the cavity 12 of the operating end face 11. The cleaning operation involves spraying cleaning liquid onto the cavity 12 of the operating end face 11 after flushing.

[0068] The cleaning frequency can be set in advance by writing it into the control start device 30. Then, the number of people flushing can be obtained by the data collected by the signal acquisition device 20. When the number of people flushing is the same as the preset frequency, the electronic water valve is controlled to perform flushing operation on the cavity 12 of the operating end face and / or the cleaning module performs cleaning operation on the cavity 12 of the operating end face.

[0069] The implementation principle is as follows:

[0070] When a user is near the urinal, the infrared sensor emits a signal. When a person blocks the infrared light, the receiver receives the reflected signal, which includes the location of the block. Therefore, the signal acquisition device 20 generates a sensing signal based on the location of the block and a preset distance, and sends the sensing signal to the control activation device 30.

[0071] The signal acquisition device 20 acquires the obstruction position in real time and generates a sensing signal based on the obstruction position and a preset distance. The control start module is signal-connected to the signal acquisition device 20 to receive the sensing signal and generates a switch start command based on the sensing signal. The control start device 30 is also used to control the solenoid valve to open the flushing operation based on the switch start command. The sealing and odor-proof mechanism 40 is electrically connected to the control start device 30 to receive the switch start command, monitors the water pressure value in real time based on the switch start command, generates a drainage operation signal based on the water pressure value and a preset value, and sends the drainage operation signal to the control start device 30. The control start device 30 receives the drainage operation signal and generates a switch close command based on the drainage operation signal and the sensing signal, and controls the solenoid valve to close the flushing operation based on the switch close command.

[0072] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
