Description

Technical Field

[0001] The utility model relates to the technical field of sanitary ware equipment, in particular to a background suppression sanitary ware sensor, and an induction self-starting device with a background suppression sanitary ware sensor. Background Art

[0002] In modern sanitary facilities, the introduction of automatic induction technology has greatly improved the convenience of use and the hygiene standard. In particular, products such as induction faucets, toilets, urinals, etc. are usually equipped with infrared reflection sensors to sense the approach of users and activate corresponding functions within the effective range, such as turning on the water flow, flushing, etc. The working principle of the infrared reflection sensor is based on the emission and reception of infrared rays, and it judges whether there is an object approaching by detecting the reflection intensity of the infrared rays. However, this technology has significant limitations and deficiencies, especially in the sanitary environment.

[0003] The limitations of the prior art are as follows:

[0004] 1. Influence of object color and material: The performance of the infrared reflection sensor is significantly affected by the surface color and material of the object. For example, light-colored objects or surfaces with high reflectivity (such as mirrors, white ceramic sinks) will cause the reflection signal to increase, so that the sensor may be triggered even before the object has completely entered the effective sensing area; on the contrary, dark objects or light-absorbing materials (such as some clothes, leather shoes) may weaken the reflection signal, and the sensor may not be able to respond correctly even when the object is approaching.

[0005] 2. Influence of on-site lighting conditions: Changes in external lighting conditions will also interfere with the normal operation of the infrared reflection sensor. In a strong light environment, the background light may increase or interfere with the reflection signal, resulting in misjudgment; while in low light conditions, the sensitivity of the sensor may decrease, affecting its normal sensing.

[0006] 3. Cost and power consumption problems: Some improved sensors, such as PSD (Position Sensitive Detector) induction devices, TOF (Time of Flight) induction devices, microwave induction devices, and ultrasonic induction devices, although they overcome the above problems to a certain extent, they bring new problems such as high cost, high power consumption, complex installation, poor waterproof performance, or too wide sensing area and easy to be mis-triggered. Especially for the sanitary occasion, these problems are particularly prominent.

[0007] Among them:

[0008] Although the PSD induction device can provide high position accuracy, due to its numerous components, high cost, and strict installation requirements, it is not easy to popularize.

[0009] The TOF sensing device measures distance using the time of flight of light. However, it has a high cost and high power consumption, making it unsuitable for the bathroom scenario where continuous long-term operation is required.

[0010] Due to its 180° wide-angle emission characteristic, the microwave sensing device is prone to false triggering when multiple workstations are sensed simultaneously, and its high power consumption is not conducive to energy conservation and environmental protection.

[0011] Although the ultrasonic sensing device has a relatively low cost, it requires drilling holes during installation, which not only damages the aesthetics of the bathroom equipment but also has poor waterproof performance and is not suitable for long-term use in a humid environment.

[0012] In summary, the existing technologies have various limitations in terms of adaptability, cost, power consumption, ease of installation, and waterproof performance. There is an urgent need for a new sensing technology that can overcome the above shortcomings and achieve an efficient, accurate, low-cost, low-power, and easy-to-install and maintain bathroom sensing solution.

In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0059] In modern bathroom facilities, the introduction of automated sensing technology has greatly improved the convenience of use and hygiene standards. In particular, products such as inductive faucets, toilets, urinals, etc. are usually equipped with infrared reflection sensors to sense the approach of users and activate corresponding functions within an effective range, such as turning on the water flow, flushing, etc. The working principle of the infrared reflection sensor is based on the emission and reception of infrared rays, and it determines whether an object is approaching by detecting the reflection intensity of the infrared rays. However, this technology has significant limitations and deficiencies, especially in the bathroom environment.

[0060] The limitations of the prior art are as follows:

[0061] 1. Influence of object color and material: The performance of the infrared reflection sensor is significantly affected by the color and material of the object surface. For example, light-colored objects or surfaces with high reflectivity (such as mirrors, white ceramic sinks) will cause the reflection signal to increase, which may trigger the sensor even before the object has fully entered the effective sensing area; on the contrary, dark-colored objects or light-absorbing materials (such as certain clothes, leather shoes) may weaken the reflection signal, and the sensor may not be able to respond correctly even when the object is close.

[0062] 2. Influence of on-site lighting conditions: Changes in external lighting conditions can also interfere with the normal operation of the infrared reflection sensor. In a strong light environment, the background light may enhance or interfere with the reflection signal, resulting in misjudgment; while in low light conditions, the sensitivity of the sensor may decrease, affecting its normal sensing.

[0063] 3. Cost and power consumption issues: Some improved sensors, such as PSD (Position Sensitive Detector) sensing devices, TOF (Time of Flight) sensing devices, microwave sensing devices, and ultrasonic sensing devices, although they overcome the above problems to a certain extent, they each bring new problems such as high cost, high power consumption, complex installation, poor waterproof performance, or an overly wide sensing area that is prone to false triggering. Especially for bathroom applications, these problems are particularly prominent.

[0064] Among them:

[0065] Although the PSD induction device can provide high position accuracy, due to its numerous components, high cost, and strict installation requirements, it is not easy to popularize.

[0066] The TOF induction device measures distance using the time of flight of light. However, it has a high cost and high power consumption, making it unsuitable for the bathroom scenario where long-term continuous operation is required.

[0067] Due to its 180° wide-angle emission characteristic, the microwave induction device is prone to false triggering when multiple workstations are sensed simultaneously, and its high power consumption is not conducive to energy conservation and environmental protection.

[0068] Although the ultrasonic induction device has a low cost, it needs to be drilled during installation, which not only damages the aesthetics of the bathroom equipment but also has poor waterproof performance and is not suitable for long-term exposure to a humid environment.

[0069] In summary, the existing technologies have various limitations in terms of adaptability, cost, power consumption, ease of installation, and waterproof performance. There is an urgent need for a new type of induction technology that can overcome the above shortcomings and achieve an efficient, accurate, low-cost, low-power, and easy-to-install and maintain bathroom induction solution.

[0070] Therefore, as Figures 1 to 9As shown, the present utility model provides a background suppression bathroom sensor, which includes a transmitting module 200 installed on a base 100 and a receiving module 300 installed on the base 100. Among them, the base 100 is installed on a bathroom device. The transmitting module 200 includes a light emitting element 210 and a transmitting lens 220. The light emitting element 210 is used to emit light, and the transmitting lens 220 is located on the emitting side of the light emitting element 210 to focus the light and emit it directly outward. In addition, the receiving module 300 includes a first position sensitive element 310, a second position sensitive element 320, and a receiving lens 330. The receiving lens 330 is located at the front end of the first position sensitive element 310 and the second position sensitive element 320. In some applications, the receiving lens 330 is used to focus the light reflected by an occluder within a first distance range in front of the light emitting element 210 and project it onto the first position sensitive element 310 to communicate with the bathroom device and drive the bathroom device to start running. In some applications, the receiving lens 330 is used to focus the light reflected by an occluder within a second distance range behind the first distance range and project it onto the second position sensitive element 320 to interrupt communication with the bathroom device and drive the bathroom device to remain closed. It is easy to understand that in front of the transmitting module 200 is a background object 500. When a target object 400 enters an appropriate position between the transmitting module 200 and the background object 500, that is, within the first distance range in front of the light emitting element 210, the target object 400 will block the light emitted by the light emitting element 210 and reflect it to the first position sensitive element 310. Thus, an induction signal is sent to start the bathroom device for the user to use. It should be noted that by integrating the transmitting module 200, the first position sensitive element 310, the second position sensitive element 320, as well as the transmitting lens 220 and the receiving lens 330, precise and stable control of the bathroom device is achieved, effectively overcoming the limitations of traditional induction technologies. Among them, the use of the transmitting lens 220 ensures the focusing and orientation of light, improves the utilization efficiency of light, reduces external interference, makes the induction distance more precisely controllable, and the design of the receiving lens 330 allows for adjustment to adapt to different induction requirements, ensuring stable induction effects for both light and dark objects and in both strong light and weak light environments. In addition, the cooperation of the dual PD sensors of the first position sensitive element 310 and the second position sensitive element 320 realizes intelligent management of the operating state of the bathroom device, avoiding both the embarrassment of starting when not in place or not starting when in place, reducing energy consumption, and enhancing the intelligent level and user experience of the device, having significant advantages in improving induction accuracy, adaptability, durability, and energy conservation.

[0071] Refer again to Figure 1, the base 100 has a first cavity 101, a second cavity 102, and a cavity wall 110 that separates the first cavity 101 and the second cavity 102. The openings of the first cavity 101 and the second cavity 102 are arranged on the same side of the base 100. The light-emitting element 210 is disposed in the first cavity 101, and the first position-sensitive element 310 and the second position-sensitive element 320 are disposed in the second cavity 102. It can be understood that the cavity wall 110 can isolate the light-emitting element 210 from the first position-sensitive element 310 and the second position-sensitive element 320, so that the cavity wall 110 can isolate the light emitted by the light-emitting element 210, preventing the light emitted by the light-emitting element 210 from being refracted in the base 100 to the first position-sensitive element 310 or the second position-sensitive element 320, which may cause incorrect sensing by the sensor, improving the clarity of the signal, and ensuring the high precision and stability of the sensor. In some specific embodiments, the first cavity 101 is funnel-shaped, the light-emitting element 210 is installed at the small end of the first cavity 101, the opening of the first cavity 101 is located at the large end of the first cavity 101, and the light-emitting element 210 emits light in the direction of the opening of the first cavity 101. Thus, it avoids the side wall of the first cavity 101 from blocking the light emitted by the light-emitting element 210, and the funnel-shaped structure enables the light emitted by the light-emitting element 210 to be effectively converged, forming a narrower and more concentrated light beam, enhancing the penetration power and sensing range of the light, while ensuring that the light is accurately projected onto the target area in accordance with the preset direction, reducing energy loss.

[0072] Referring to Figure 2 , in some embodiments of the present invention, the second cavity 102 extends obliquely towards the opening, and the opening of the second cavity 102 is inclined towards the direction close to the first cavity 101, so that the second cavity 102 can follow the inclination of the reflected light and avoid the side wall of the second cavity 102 from blocking the reflected light. Thus, the receiving lens 330 can better capture the reflected light, improving the receiving efficiency. At the same time, the inclination of the opening helps to prevent water, reducing the possibility of moisture or other liquids entering the receiving module 300, enhancing the waterproof performance and durability of the entire system.

[0073] In some embodiments of the present invention, the background suppression bathroom sensor is used to control the opening of water. Specifically, the bathroom device is provided with a water outlet mechanism and a solenoid valve 900 disposed in the water outlet mechanism. The first position-sensitive element 310 communicates with the solenoid valve 900 to drive the water outlet mechanism to open, and the second position-sensitive element 320 is interrupted from communicating with the solenoid valve 900 to drive the water outlet mechanism to remain closed, achieving instant response and precise control of the bathroom device, reducing waste of water resources, and improving the user experience at the same time.

[0074] In some embodiments, the receiving lens 330 is adjustably mounted on the base 100 to adjust the position within the first distance range. This allows the user to adjust the sensing distance according to the actual usage environment, enhancing the adaptability and flexibility of the sensor and meeting the requirements of different scenarios and user preferences. Specifically, the second position-sensitive element 320 is located on the side of the first position-sensitive element 310 facing the light-emitting element 210. In application, moving the receiving lens 330 to the left will shorten the detection distance; moving the receiving lens 330 to the right will lengthen the detection distance; reducing the distance between the receiving lens 330 and the position-sensitive element will decrease the detection distance; and raising the distance between the receiving lens 330 and the position-sensitive element will increase the detection distance.

[0075] Referring again to Figure 3 and Figure 4 In some embodiments of the present invention, the sanitary ware device is a faucet 600. The faucet 600 includes a vertical pipe portion 610 and a horizontal pipe portion 620 communicating with the top end of the vertical pipe portion 610. The bottom end of the vertical pipe portion 610 is for water inlet. The bottom of the end of the horizontal pipe portion 620 away from the vertical pipe portion 610 has a water outlet 6202. An installation hole 6201 is provided at the bottom of the horizontal pipe portion 620. The installation hole 6201 is located on the side of the water outlet 6202 close to the vertical pipe portion 610. The base 100 is installed in the installation hole 6201. On the one hand, the sensor can be seamlessly integrated into the structure of the faucet 600, ensuring both good appearance integration and simplifying the installation process, thus enhancing the user's installation experience. On the other hand, it enables the base 100 to avoid the area below the water outlet 6202, preventing the base 100 from obstructing the user from reaching below the water outlet 6202 to wash hands. Optionally, a solenoid valve 900 is used to open and close the water outlet 6202. Thus, the water outlet 6202 of the base 100 can be controlled to open and close through the solenoid valve 900, eliminating the need for manual operation of the water outlet 6202, and further facilitating use.

[0076] In some specific embodiments, a convex ring protruding downward is provided at the bottom of the horizontal pipe portion 620. The convex ring is used to form the water outlet 6202. Thus, the water outlet 6202 can protrude from the bottom surface of the horizontal pipe portion 620, and further, it is convenient for users to identify the position of the water outlet 6202. Further, the bottom end of the axis of the water outlet 6202 is inclined away from the vertical pipe portion 610. Thus, the water outlet direction of the water outlet 6202 can be inclined towards the user. Further, when the user washes hands, it is not necessary to put the hand entirely under the water outlet 6202 for handwashing, improving the user experience. Specifically, the bottom end of the axis of the water outlet 6202 is inclined away from the vertical pipe portion 610 by 5±2 degrees. Thus, the water outlet inclination angle of the water outlet 6202 is controlled within a small angle range, avoiding the water outlet inclination angle of the water outlet 6202 being too large and spraying on the user. In some specific embodiments, the outer wall of the convex ring is in arc transition with the bottom of the horizontal pipe portion 620. Thus, the appearance of the connection position between the convex ring and the horizontal pipe portion 620 is more beautiful. In some specific embodiments, the horizontal pipe portion 620 and the vertical pipe portion 610 are perpendicular to each other. Thus, the appearance of the main body is beautiful. Optionally, the inner angle at the connection between the horizontal pipe portion 620 and the vertical pipe portion 610 is in arc transition, reducing the sharp edges at the connection between the horizontal pipe portion 620 and the vertical pipe portion 610. Further, the outer pipe of the main body is smoother and more beautiful.

[0077] It can be understood that when the sensor detects an obstruction, it can control the solenoid valve 900 to open the water outlet 6202. Thus, the effect of automatic induction of water on and off of the faucet 600 is achieved. At the same time, the sensor has the advantages of accurate detection and low cost, can accurately detect the obstruction, and has high induction accuracy, avoiding both spraying water when the obstruction is not in place and not spraying water when the obstruction is in place. Specifically, the first distance range is the set water outlet induction distance range, and the second distance range is the set distance range beyond the water outlet induction distance.

[0078] Further, the mounting hole 6201 is an oblong hole. Thus, on the one hand, the mounting hole 6201 can match the shape of the base 100. On the other hand, it is convenient to adjust the mounting position of the base 100 on the mounting hole 6201, and further adjust the position of the base 100 on the horizontal pipe portion 620. In some specific embodiments, the length direction of the mounting hole 6201 is arranged along the length direction of the horizontal pipe portion 620. Thus, the base 100 can adjust its position along the length direction of the mounting hole 6201, and further, it is convenient to adjust the distance between the base 100 and the water outlet 6202. In some specific embodiments, the connection line between the center of the mounting hole 6201 and the center of the water outlet 6202 is parallel to the length direction of the horizontal pipe portion 620. Thus, when the user reaches out to the water outlet 6202 from the direction away from the vertical pipe portion 610 of the water outlet 6202, the user's hand can enter the detection area of the base 100 along the reaching direction, so that the base 100 mounted on the mounting hole 6201 can detect the user's hand in time.

[0079] Referring again to Figures 5 to 7 , in some embodiments of the present utility model, the sanitary ware device is a urinal 700. The urinal 700 includes a urinal body 710. The rear side of the urinal body 710 is used for mounting on the wall, and the front side has a urinal trough 7101. The bottom of the urinal trough 7101 has a liquid discharge port 7102, so that the urinal trough 7101 of the urinal body 710 can be used for men to urinate. In application, the sensor detects the user's waist in time to achieve automatic water discharge.

[0080] Specifically, the water outlet mechanism has a water passage 920, a water inlet passage 910 communicating with the rear side of the water passage 920, and a water outlet passage 930 communicating with the front side of the water passage 920. The water outlet passage 930 is arranged downward and is used to flush the urinal trough 7101 downward, ensuring the efficiency and hygiene of the flushing process. Through the optimized design of the water outlet passage 930, the effective flushing of the urinal trough 7101 is realized, improving the cleaning effect. Further, the water outlet mechanism further includes an installation pipe 720 and a water outlet housing 730 connected to the front end of the installation pipe 720. The installation pipe 720 is used to connect the urinal body 710. The water outlet housing 730 is located inside the urinal trough 7101. The rear end of the installation pipe 720 is used to form the water inlet passage 910. The water outlet housing 730 has a fan-shaped cavity 740. The small end of the fan-shaped cavity 740 communicates with the front end inside the installation pipe 720. The inside of the installation pipe 720 and the fan-shaped cavity 740 cooperate to form the water passage 920. The large end of the fan-shaped cavity 740 extends downward, and the large end of the fan-shaped cavity 740 is open. The large end of the fan-shaped cavity 740 is used to form the water outlet passage 930. It can be understood that water flows through the inside of the installation pipe 720 to the small end of the fan-shaped cavity 740, and then sprays out from the large end of the fan-shaped cavity 740, so that the water sprayed by the water outlet mechanism can rush towards the urinal trough 7101 in a fan shape, making the flushing range of the water outlet mechanism for the urinal trough 7101 larger. Thus, the flushing of the urinal trough 7101 by the water outlet mechanism is more comprehensive. Optionally, the large end of the fan-shaped cavity 740 is inclined towards the rear side of the urinal body 710, so that the water outlet mechanism can spray water towards the inner wall of the urinal trough 7101, and further, the flushing of the inner wall of the urinal trough 7101 by the water outlet mechanism is cleaner.

[0081] In some specific embodiments, the water outlet mechanism further includes an installation housing 750 and a front cover 760. The installation housing 750 is used to install the sensor. The front side of the water outlet housing 730 has an installation cavity 770. The installation housing 750 is arranged in the installation cavity 770. The front cover 760 is used to cover the installation cavity 770. The front cover 760 also has a first through groove 780. The first through groove 780 accommodates the emitted and received light of the sensor, thus avoiding the sensor being exposed outside and affecting the service life of the sensor.

[0082] Further, the installation pipe 720 passes through the urinal body 710. The water outlet housing 730 abuts against and is limited by the front side of the urinal body 710. The rear end of the installation pipe 720 has a threaded portion. The locking bolt cooperates with the threaded portion to fix the water outlet mechanism on the urinal body 710, thus facilitating the installation of the water outlet mechanism on the urinal body 710. In some specific embodiments, a gasket is also sleeved on the installation pipe 720, and the gasket is located between the locking bolt and the urinal body 710.

[0083] Further, the front cover 760 and the water outlet housing 730 are detachably connected by bolts. Thus, the urinal 700 can replace the sensor by removing the front cover 760, eliminating the need to remove the entire urinal body 710 to replace the sensor. Furthermore, the replacement of the sensor is made more convenient.

[0084] Referring again to Figure 8 and Figure 9 In some embodiments of the present invention, the sanitary ware device is an induction toilet 800. The induction toilet 800 includes a water tank 820 and a toilet seat 810. The water tank 820 is used for storing water. The water tank 820 has a water inlet 910 for connecting a water pipe. The toilet seat 810 has a water outlet 930. The water outlet mechanism includes a water pump 1000. The water pump 1000 is used to pump the water in the water tank 820 to the water outlet 930. The solenoid valve 900 is used to connect or block the water outlet 930. Through the coordinated operation of the sensor with the water pump 1000 and the solenoid valve 900, intelligent control of the flushing process is achieved, which not only improves the automation level of the bathroom but also promotes water conservation and environmental protection. Optionally, the water tank 820 is embedded in the rear side of the toilet seat 810, thus saving the occupied space of the toilet.

[0085] In some specific embodiments, the base 100 is installed on the front side of the toilet seat 810 and is used to detect the user's legs forward to control the solenoid valve 900 to open and close the water outlet mechanism. It can be understood that the sensor can automatically detect the user's legs. When the sensor detects the user's legs and the user's legs leave the sensing area, the sensor controls the water outlet mechanism to flush automatically, eliminating the operation of manual pressing for flushing and making the toilet flushing more convenient.

[0086] In some specific embodiments, the base 100 is set at a position slightly to the left or right of the center in the front of the toilet seat 810, and the sensor can sense the user's left foot or right foot. It can be understood that when the user uses the toilet, both feet of the user are respectively located at positions slightly to the left and right of the center in the front of the toilet seat 810. By setting the sensor at a position slightly to the left or right of the center in the front of the toilet seat 810, the sensor can accurately detect the user's legs. Correspondingly, an installation groove is provided on the front side of the toilet seat 810. The installation groove extends in the horizontal direction and is used for installing the sensor. Thus, it is convenient to install the sensor on the toilet seat 810 with bolts. At the same time, the installation groove extends in the horizontal direction, allowing the installation groove to have space to allow the sensor to adjust its position in the horizontal direction. Thus, it is convenient to adjust the position of the sensor according to the usage situation, and furthermore, the detection of the sensor is made more accurate.

[0087] In some specific applications, after the first position-sensitive element 310 senses that the user's leg appears within the first distance range, it emits a first sensing signal. After receiving the first sensing signal, the solenoid valve 900 opens the water outlet mechanism to output water with a first water volume and then closes the water outlet mechanism. After the first position-sensitive element 310 senses that the user's leg leaves the first distance range, it emits a second sensing signal. After receiving the second sensing signal, the solenoid valve 900 opens the water outlet mechanism to output water with a second water volume and then closes the water outlet mechanism. The water output with the second water volume is more than the water output with the first water volume. Further, the first water volume is half of the water storage capacity of the water tank 820, and the second water volume is the full water storage capacity of the water tank 820. Thus, the water output of the water outlet mechanism is made more accurate. In some specific embodiments, the solenoid valve 900 changes the time to open the water outlet mechanism to output water with the first water volume or the second water volume. Thus, it is more convenient to control the water output of the water outlet mechanism.

[0088] The induction self-starting device according to an embodiment of the present invention includes a background suppression bathroom sensor according to an embodiment of the present invention. Integrating the background suppression bathroom sensor into the induction self-starting device realizes the intelligent induction self-start function of the operation state of the bathroom device, avoiding both the embarrassment of starting without being in place or not starting when in place, reducing energy consumption, improving the intelligent level of the device and the user experience, and having significant advantages in improving induction accuracy, adaptability, durability and energy conservation.
