Description

Technical Field

[0001] The invention relates to the field of water outlet bathrooms, in particular to a radar water outlet sensing device and a power generation sensing water outlet system thereof. Background Art

[0002] Inductive water discharge is a commonly used technology. By detecting the user's body signals, a water discharge command is generated, and the control system immediately controls the water discharge from the faucet. The user can control the water discharge without manually operating the faucet. The operation is convenient, cross infection is avoided, and it is safe and hygienic. Conventionally, the user's body is detected through the infrared detection principle. However, the disadvantage of the infrared detection principle is poor penetration, that is, when the front of the infrared sensing device is blocked, the detection function will fail, that is, the infrared detection stability is poor; and because the front of the infrared sensing device cannot be blocked, the detection end of the infrared sensing device needs to be exposed to the product, that is, a hole needs to be opened on the surface of the product, which affects the appearance and structure of the product. As shown in the following patent documents: Chinese patent document CN2010205418073 discloses a wash basin, and specifically discloses: a temperature regulating control device with a hot water inlet and a cold water inlet, connected to the water outlet of an inductive water outlet device arranged on the basin through a connecting water pipe... The inductive water outlet device is: a sensor capable of sensing a human body is arranged on one side of the water outlet... The sensor is an infrared sensor; Chinese patent document CN2016205127677 discloses a novel automatic water shutoff type hand washing sink, and specifically discloses: comprising a hand washing sink body... a horizontally arranged infrared sensor is provided at the upper end of the hand washing sink body, and the infrared sensor is connected to a power supply controller...; Chinese patent document CN2019213217147 discloses an induction-type wash basin cabinet, and specifically discloses: it includes a table body and an induction water outlet device arranged on the table body... The sensor includes an infrared sensor, which is embedded in the faucet and the detection end is facing the user side of the table body.

[0003] In addition to the infrared sensing principle, some products on the market use the radar detection principle. However, traditional radar detection devices often misjudge water columns as moving objects, 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, so when using it, the user needs to first reach out to the radar detection area to trigger the radar detection module, and then move the hand to the water column position to use water, which is more troublesome. It is precisely because of the above defects that there are relatively few applications of radar detection devices on the market, such as the following patent documents: Chinese patent document CN2024104912039 discloses a water supply control system integrated at the water outlet of a faucet, specifically disclosing: comprising a faucet, a solenoid valve, a sensing radar and a microcontroller unit; the sensing radar is integrated at the water outlet of the faucet, and its microwaves are directed downward and deflected toward the direction of the faucet toward the user, and the microwaves received and transmitted by the sensing radar are Doppler microwaves... The microcontroller unit is electrically connected to the sensing radar and the solenoid valve respectively, and controls the action of the solenoid valve according to the sensing condition of the sensing radar; Chinese patent document CN2024104912062 discloses a contactless automatic water supply control system, which specifically discloses: it includes an induction radar, a micro control unit and a solenoid valve; the induction radar is an X-band Doppler microwave induction radar with a transmission power less than -10dBm, which is installed on the outside of the side wall of the ceramic sink, and the normal of the signal emitted by the induction radar is toward the water flow direction of the faucet.

[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] First embodiment: See also Figure 1-Figure 5The radar water-emergence sensing 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 in the radar detection area A; when an active object appears in the radar detection area A, the radar detection module 1 generates a detection signal; when a water column C appears in the signal shielding area B, the radar detection module 1 does not generate a detection signal. In the present radar water outlet sensing device 100, a first signal blocking component 2 is arranged in front of the radar detection module 1, and the first signal blocking component 2 can block the electromagnetic waves emitted by the radar detection module 1, thereby forming a signal shielding area B (that is, a detection blind area) in the radar detection area A in front of the radar detection module 1, and the water column C flows in the signal shielding area B, thereby effectively avoiding the radar detection module 1 from misjudging the water column C as a moving object and causing continuous water outlet; 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 of the limbs and the use of water 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, and the electromagnetic waves have strong penetrability and can penetrate non-metallic materials such as ceramics and wood, so even if there are objects blocking the front, the radar detection module 1 can still work normally, which shows that the performance is stable and reliable, and there is no need to open a hole on the product surface to install the radar water outlet sensing device 100, thereby ensuring the integrity of the product surface.

[0032] Furthermore, the first signal blocking component 2 is made of 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 part 300 is arranged above the signal shielding area B, so as to ensure that the water column C flows vertically in 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 and being misjudged; the area size of the signal shielding area B depends on at least the following conditions: ① the distance between the radar detection module 1 and the first signal blocking component 2, and ② the width (diameter) of the first signal blocking component 2.

[0033] Furthermore, the radar water-emergence sensing device 100 also includes a second signal blocking component 4, which is arranged below the radar detection module 1, and the second signal blocking component 4 is made of 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-emergence sensing device 100 from affecting the detection result.

[0034] Furthermore, the radar detection module 1 includes a radar chip 101, a voltage stabilizing circuit 102, a single-chip microcomputer 103, and a signal transceiver antenna 104, which are respectively arranged on a radar circuit board 105; the signal transceiver antenna 104, the radar chip 101, the voltage stabilizing circuit 102 and the single-chip microcomputer 103 are electrically connected to each other in sequence, and 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. Working principle of radar water-sensing device 100 (see Figure 7 ): Electromagnetic wave transmission: In the standby state, the signal transceiver antenna 104 uses the transmitting antenna to transmit high-frequency electromagnetic waves to the outside world. These electromagnetic waves are emitted in a radial diffusion manner; the transmitting antenna generates electromagnetic waves through the alternating oscillation of positive and negative charges; Target reflection: When a moving object (such as the user's hand) appears in the radar detection area A, the electromagnetic wave is reflected by the object (such as the user's hand). The reflected electromagnetic wave carries the object's information, such as distance and direction. As the object moves, the corresponding distance and direction data will change accordingly. Electromagnetic wave reception: The reflected electromagnetic waves are 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 them to the radar chip 101; Signal processing: The radar chip 101 processes the received signal through amplification, mixing, detection and other processing steps, converts the original electromagnetic wave signal into a positive level signal that can be interpreted, and sends it to the single-chip computer 103; these positive level signals include information such as distance, speed, direction, etc.; Parsing and executing instructions: The single-chip computer 103 sends the processed positive level signal to the control system (such as the control module 22 in the power generation induction water outlet system below), and the control system generates and executes corresponding instructions according to the signal, thereby opening the water outlet 300; the water column C coming out of the water outlet 300 keeps flowing in the signal shielding area B, and the radar water outlet sensing device 100 cannot detect objects in the signal shielding area B, so it will not be misjudged due to the flow of the water column C; When an 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 waves, and the radar chip 101 sends a negative level signal to the single-chip microcomputer 103. The single-chip microcomputer 103 sends the negative level to the control system. The control system generates and executes corresponding instructions based on the signal, thereby closing the water outlet 300.

[0035] Furthermore, the radar water-emergence sensing device 100 also includes a radar shell 3, and a radar circuit board 105 is arranged on one end face of the radar shell 3. The radar shell 3 is made of non-metallic material to avoid affecting the normal reception and transmission of electromagnetic waves.
