Description

Technical Field

[0001] The utility model relates to the field of water outlet sanitary wares, in particular to a radar water outlet induction device and a power generation induction water outlet system thereof. Background Art

[0002] Inductive water outlet is a commonly used technology. By detecting the body signals of users, a water outlet instruction is generated, and then the control system controls the faucet to discharge water immediately. Users can control the water outlet without manually operating the faucet, which is convenient to operate, avoids cross-infection, and is safe and hygienic. Conventionally, the infrared detection principle is used to detect the user's body. However, the disadvantage of the infrared detection principle is poor penetration. That is, when the front of the infrared induction device is blocked, the detection function will fail, that is, the infrared detection stability is poor. Moreover, since the front of the infrared induction device cannot be blocked, the detection end of the infrared induction device needs to be exposed outside the product, that is, holes need to be opened on the product surface, resulting in affecting the appearance and structure of the product, etc. Such as the following patent documents:

[0003] Chinese Patent Document CN2010205418073 discloses a smart washbasin, and specifically discloses: a temperature adjustment control device with a hot water inlet and a cold water inlet, which is communicated with the water outlet of an inductive water outlet device arranged on the washbasin through a connecting water pipe... The inductive water outlet device is: a sensor capable of sensing the human body is arranged on one side of the water outlet... The sensor is an infrared sensor;

The sensor includes an infrared sensor, and the infrared sensor is embedded in the faucet and the detection end faces the side of the table body facing the user.

[0006] In addition to the infrared induction principle, some products on the market use the radar detection principle. However, traditional radar detection devices often misjudge the water column as a moving object, resulting in continuous water discharge even when people leave the faucet. In order to overcome the misjudgment problem, the prior art needs to set the water column away from the radar detection area. Therefore, when users use it, they need to first reach their hands to the radar detection area to trigger the radar detection module, and then move their hands to the water column position to use water. Such operation is relatively troublesome. It is precisely due to the above defects that the application of radar detection devices in the market is relatively small. Such as the following patent documents:

[0007] Chinese Patent Document CN2024104912039 discloses a water supply control system integrated at the water outlet end of a faucet, specifically disclosing: including a faucet, a solenoid valve, an induction radar, and a micro-control unit; the induction radar is integrated at the water outlet end of the faucet, the direction of its microwave radiation is downward and deflected towards the direction where the faucet faces the user, and the microwave received and transmitted by the induction radar is Doppler microwave... The micro-control unit is electrically connected to the induction radar and the solenoid valve respectively, and controls the operation of the solenoid valve according to the induction situation of the induction radar;

[0008] Chinese Patent Document CN2024104912062 discloses a non-contact automatic water supply control system, specifically disclosing: including an induction radar, a micro-control unit, and a solenoid valve; the induction radar is a Doppler microwave induction radar in the X-band with a transmission power less than -10 dBm, which is installed outside the side wall of a ceramic sink, and the normal line of the signal emitted by the induction radar faces the water flow direction of the faucet for water supply.

[0009] In view of the problem of detection misjudgment existing in radar induction water outlet products on the market, it is necessary to further improve them. Utility Model Content

[0040] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0041] First embodiment:

[0042] Refer to Figures 1-5, the radar water outlet induction device 100 involved in this embodiment includes a radar detection module 1 and a first signal blocking component 2. During operation, a radar detection area A is formed in front of the radar detection module 1. The first signal blocking component 2 is arranged in front of the radar detection module 1, so that a signal shielding area B is formed within the radar detection area A; when a moving object appears within the radar detection area A, the radar detection module 1 generates a detection signal; when a water column C appears within the signal shielding area B, the radar detection module 1 does not generate a detection signal. In this radar water outlet induction device 100, the first signal blocking component 2 is arranged in front of the radar detection module 1. The first signal blocking component 2 can block the electromagnetic wave emitted by the radar detection module 1, thereby forming a signal shielding area B (i.e., a detection blind area) within the radar detection area A in front of the radar detection module 1. The water column C flows within the signal shielding area B, thereby effectively preventing the radar detection module 1 from misjudging the water column C as a moving object and causing continuous water outflow; by forming a blind area, the water column C can be arranged in front of the radar detection module 1, that is, both the sensing limb and water use can be completed in front of the radar detection module 1, which is convenient to use; in addition, the radar detection module 1 relies on electromagnetic waves for detection. The electromagnetic wave has relatively strong penetrability and can penetrate non-metallic materials such as ceramics and wood. Therefore, although there are objects blocking in front, the radar detection module 1 can still work normally, indicating stable and reliable performance. Moreover, there is no need to open holes on the product surface to install the radar water outlet induction device 100, ensuring the integrity of the product surface.

[0043] Further, the first signal blocking component 2 is made of a metal material and is cylindrical. The first signal blocking component 2 is fixedly arranged relative to the radar detection module 1; the first signal blocking component 2 extends vertically, and the water outlet of the water outlet component 300 is arranged above the signal shielding area B to ensure that the water column C flows vertically within the signal shielding area B and prevent the water column C from exceeding the signal shielding area B and entering the radar detection area A to be misjudged; the area size of the signal shielding area B depends at least on the following conditions: ① the distance between the radar detection module 1 and the first signal blocking component 2, ② the width (diameter) of the first signal blocking component 2.

[0044] Further, the radar water outlet induction device 100 further includes a second signal blocking component 4. The second signal blocking component 4 is arranged below the radar detection module 1, and the second signal blocking component 4 is made of a metal material; by arranging the second signal blocking component 4 below the radar detection module 1, it can further prevent the water below the radar water outlet induction device 100 from affecting the detection result.

[0045] Further, the radar detection module 1 includes a radar chip 101, a voltage stabilization circuit 102, a single-chip microcomputer 103, and a signal transceiver antenna 104 respectively disposed on the radar circuit board 105; the signal transceiver antenna 104, the radar chip 101, the voltage stabilization circuit 102, and the single-chip microcomputer 103 are electrically connected to each other in sequence, the single-chip microcomputer 103 is electrically connected to a control system for executing control instructions, and the radar detection area A is located in front of the signal transceiver antenna 104;

[0046] The working principle of the radar water outlet induction device 100 (see Figure 7 ):

[0047] Electromagnetic wave emission: In the standby state, the signal transceiver antenna 104 uses the transmitting antenna to emit high-frequency electromagnetic waves to the outside world, and these electromagnetic waves are emitted in a radiation diffusion manner; the transmitting antenna generates electromagnetic waves through the alternating oscillation of positive and negative charges;

[0048] Target reflection: When an active object (such as the user's hand) appears in the radar detection area A, the electromagnetic wave is reflected when it encounters the object (such as the user's hand), and the reflected electromagnetic wave carries information about the object, such as distance and direction, etc.; as the object moves, the corresponding distance, direction and other data will change accordingly;

[0049] Electromagnetic wave reception: The reflected electromagnetic wave is received by the receiving antenna on the signal transceiver antenna 104, and the signal transceiver antenna 104 amplifies and processes these signals to extract relevant information data of the target and send it to the radar chip 101;

[0050] Signal processing: The radar chip 101 processes the received signals through steps such as amplification, mixing, and detection, converts the original electromagnetic wave signal into a positive level signal that can be interpreted, and sends it to the single-chip microcomputer 103; these positive level signals include information such as distance, speed, and direction;

[0051] Analysis and execution of instructions: The single-chip microcomputer 103 sends the processed positive level signal to the control system (such as the control module 22 in the following power generation induction water outlet system), and the control system generates and executes corresponding instructions according to this signal, and then opens the water outlet part 300; the water column C coming out of the water outlet part 300 keeps flowing in the signal shielding area B, and the radar water outlet induction device 100 cannot detect the objects in the signal shielding area B, so it will not be misjudged due to the flow of the water column C;

[0052] When the object in the radar detection area A leaves or stops, the receiving antenna on the signal transceiver antenna 104 does not receive the changing electromagnetic wave, the radar chip 101 sends a negative level signal to the single-chip microcomputer 103, and the single-chip microcomputer 103 sends the negative level to the control system, and the control system generates and executes corresponding instructions according to this signal, and then closes the water outlet part 300.

[0053] Furthermore, the radar water outlet sensing device 100 further includes a radar housing 3. The radar circuit board 105 is disposed on one end face of the radar housing 3. The radar housing 3 is made of a non-metallic material to avoid affecting the normal transmission and reception of electromagnetic waves. A fixing portion 301 for fixing the first signal blocking member 2 is integrally formed on the inner side of the radar housing 3.

[0054] See Figures 7-13 , the power generation induction water outlet system involved in this embodiment includes

[0055] For the above-mentioned radar water outlet sensing device 100, in order to facilitate the detection of the user's hand, the radar water outlet sensing device 100 is preferably disposed on the water outlet member 300. The water outlet member 300 in this embodiment is a faucet;

[0056] A power generation control device 200, which includes a power generation component, a solenoid valve 20, a power supply module 24, and a control module 22. The water inlet end of the power generation component communicates with the water inlet waterway 2101, and the solenoid valve 20 is disposed on the water inlet waterway 2101; the control module 22 is electrically connected to the solenoid valve 20, the radar detection module 1, and the power supply module 24, and controls the solenoid valve 20 to open the water inlet waterway 2101 according to the detection signal fed back by the radar detection module 1; the power generation component includes a power generation water turbine 19, a power generation magnetic ring 18, and a power generation coil 17. The power generation water turbine 19 is rotatably disposed, the power generation magnetic ring 18 is disposed on the power generation water turbine 19 and rotates therewith, and the power generation coil 17 is disposed inside the power generation magnetic ring 18 and is electrically connected to the power supply module 24; when the water flow drives the power generation water turbine 19 to rotate, the power generation magnetic ring 18 rotates with the power generation water turbine 19, and the power generation coil 17 relatively cuts the magnetic induction line, so that the power generation coil 17 generates electric energy for charging the power supply module 24;

[0057] The water outlet end of the power generation component communicates with the water outlet waterway 2104, and the water column coming out of the power generation control device 200 flows within the signal shielding area B.

[0058] A power generation component is provided in this power generation induction water outlet system. The water pressure is used to trigger the power generation component, so that the power generation component operates to generate electric energy and store it on the power supply module 24, providing the required electric energy for the normal operation of the radar water outlet sensing device 100 and the solenoid valve 20. The electric energy required by this water outlet system can be self-sufficient, without connecting to an external power grid, getting rid of the bondage of the power cord. Therefore, it can be installed at any position and is durable.

[0059] Further, the power generation water turbine 19 includes a wheel sleeve 1901 and wheel blades 1902. A plurality of wheel blades 1902 are evenly distributed annularly on the outer side of the wheel sleeve 1901. The middle part of the wheel blade 1902 is bent along the water flow direction D to form a first water converging part 1903 and a second water converging part 1904. The first water converging part 1903 and the second water converging part 1904 can respectively guide the water flow to the middle part of the wheel blade 1902, so that the water pressure can be concentrated to push the power generation water turbine 19 to rotate, and at the same time, its rotation can be made more stable.

[0060] Further, the wheel blade 1902 is inclined relative to the diameter of the wheel sleeve 1901. A water converging port 1905 is formed between the inclined end of the wheel blade 1902 and the surface of the wheel sleeve 1901. The water body in the water inlet waterway 2101 flows along the tangential direction of the wheel sleeve 1901 (i.e., the water flow direction D) and enters the water converging port 1905 to act on the inner side wall of the wheel blade 1902, thereby effectively pushing the power generation water turbine 19 to rotate.

[0061] Further, a water inlet valve port 2102 is arranged inside the water inlet waterway 2101; the electromagnetic valve 20 includes a diaphragm 2001, a magnetic attraction component (not shown in the figure, the magnetic attraction component can be a component made of a metal material and can be magnetically attracted) and an electromagnetic component 2003 (the electromagnetic component 2003 generates a magnetic field when energized). The diaphragm 2001 is soft and deformable. An elastic member 2002 is arranged between the diaphragm 2001 and the electromagnetic component 2003. The elastic member 2002 acts on the diaphragm 2001 to elastically seal the water inlet valve port 2102. The magnetic attraction component is arranged on the diaphragm 2001, and the electromagnetic component 2003 is electrically connected to the control module 22; when the control module 22 receives the detection signal fed back by the radar detection module 1, the control module 22 controls the electromagnetic component 2003 to generate a magnetic attraction force and adsorb the magnetic attraction component. The magnetic attraction component drives the diaphragm 2001 to move, so that the diaphragm 2001 opens the water inlet valve port 2102 to conduct the water inlet waterway 2101. At this time, the elastic member 2002 is compressed and stores energy; when the detection signal fed back by the radar detection module 1 disappears, the electromagnetic component 2003 is powered off to make the magnetic field disappear, and the elastic member 2002 randomly releases the elastic force to make the diaphragm 2001 seal the water inlet valve port 2102.

[0062] Further, the power generation assembly further includes a first water passing housing 12 and a second water passing housing 21. The power generation coil 17 is fixedly arranged on the first water passing housing 12. The power generation water turbine 19 is rotatably arranged on the first water passing housing 12. The power generation coil 17 and the power generation water turbine 19 are coaxially matched. The power generation assembly is placed in the water passing cavity 2103 on the second water passing housing 21. The electromagnetic valve 20 and the water inlet waterway 2101 are respectively arranged on the second water passing housing 21.

[0063] Furthermore, the water inlet waterway 2101 and the water outlet waterway 2104 are respectively integrally formed on the second water-passing shell 21, and the first water-passing shell 12 is provided with a cover body 13 for shielding and protecting the generating coil 17. The first water-passing shell 12 and the second water-passing shell 21 are sealed to each other by a sealing ring 14. A rotating bearing 16 is provided on the first water-passing shell 12, and the generating water wheel 19 is connected to the rotating bearing 6 via a rotating shaft 15. The generating coil 17 and the generating water wheel 19 are coaxially matched with each other.
