[0029] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0030] like Figures 1 to 8 As shown, this utility model provides a faucet sensor module, including: a housing 1 having a closed end 21 and an open end 22, the closed end 21 being provided with a light-transmitting sensor window; a light-blocking pad 3 disposed inside the housing 1, the front end face 11 of the light-blocking pad 3 abutting against the closed end 21, the rear end face 15 of the light-blocking pad 3 being close to the open end 22, the light-blocking pad 3 having a pair of through slots, the front opening of the slots corresponding to the sensor window, the surface of the light-blocking pad 3 being treated with black; and a TOF sensor chip 4 disposed inside the housing 1. Inside the outer casing 1, the transmitter 9 and receiver 10 of the TOF sensor chip 4 are respectively secured in the pair of slots 7 and 8, and the TOF sensor chip 4 is sealed to the opening 22; the TOF signal line 2 is connected to the TOF sensor chip 4 and extends to the outside of the outer casing 1 through the opening 22; the control module 24 includes a control chip 17, which is communicatively connected to the TOF signal line 2 and receives the sensing signal from the TOF sensor chip 4 through the TOF signal line 2.

[0031] TOF sensing technology is an active detection technology. When the sensing module is installed on the faucet, the transmitter of the TOF sensing chip 4 emits 850nm infrared light through the sensing window. When the infrared light encounters an obstacle (such as a user blocking the faucet with their hand), it returns through the sensing window and is received by the receiver. The TOF sensing chip 4 then generates a sensing signal, which is sent to the control chip 17 through the TOF signal line 2. The control chip 17 receives the sensing signal and drives the faucet solenoid valve to open or close according to the sensing signal.

[0032] In the aforementioned sensing module, the light-blocking pad 3 is used to assemble the TOF sensing chip 4 inside the housing 1, serving a fixing and supporting function. The light-blocking pad 3 has a pair of through slots, and the transmitting end 9 and receiving end 10 of the TOF sensing chip 4 are respectively inserted into the pair of slots 7 and 8, thereby connecting with the light-blocking pad 3. At the same time, the surface of the light-blocking pad 3 is treated with black to prevent infrared light crosstalk, thereby ensuring the normal operation of the TOF sensing chip 4.

[0033] The outer shell 1 is made of transparent PC material, which can ensure the transmission of light and reduce the light loss rate.

[0034] This invention provides a faucet sensing module, designed based on TOF sensing detection technology. This module offers higher accuracy and reliability, stronger resistance to ambient light interference, and makes the smart sensor faucet more reliable in use. Furthermore, the sensing module is more compact in structure and smaller in size, making it easier to use on faucets.

[0035] In a preferred embodiment, the light-blocking pad 3 in the faucet sensor module is made of silicone. The silicone material provides a soft seal for the internal electronic components and facilitates assembly.

[0036] In a preferred embodiment, in the faucet sensor module, a sealant is applied between the TOF sensor chip 4 and the opening end 22 to seal the gap between them. This sealing design ensures the waterproof effect of the TOF sensor chip 4 and guarantees its normal operation. Simultaneously, the sealant also serves to fix the TOF sensor chip 4 in place.

[0037] In a preferred embodiment, in the faucet sensor module, the open end 22 is provided with limiting ribs 5. The limiting ribs 5 are engaged with the outer surface of the TOF sensor chip 4 to fix the TOF sensor chip 4 inside the housing 1. The limiting ribs 5 inside the housing 1 can limit the position of the TOF sensor chip 4, ensuring that the TOF sensor chip 4 is installed in place. The limiting ribs 5 can be distributed on the lower and upper sides of the open end 22, with two on the lower side and one on the upper side.

[0038] In a preferred embodiment, the TOF signal line 2 in the faucet sensing module is waterproof. The waterproof structure of the TOF signal line 2 makes the contact between the TOF sensing chip 4 and the TOF signal line 2, as well as between the control module 24 and the TOF signal line 2, more reliable.

[0039] Furthermore, the outer casing 1 has a positioning rib 6 on the outer peripheral surface of the opening end 22. The positioning rib 6 engages with the corresponding positioning groove structure on the faucet to achieve the positioning and installation of the sensing module. The positioning rib 6 can be set as needed, and the number can be two.

[0040] In a preferred embodiment, the control module 24 of the faucet sensing module further includes a solenoid valve control line 14, the control chip 17 is communicatively connected to the solenoid valve control line 14, the solenoid valve control line 14 is connected to the faucet solenoid valve, and the control chip 17 sends control signals to the faucet solenoid valve through the solenoid valve control line 14.

[0041] When the sensing module is working, when the TOF sensing chip 4 generates a sensing signal, the control chip 17 receives the sensing signal and generates a control signal based on the sensing signal. The control chip 17 then sends the control signal to the faucet solenoid valve via the solenoid valve control line 14, thereby controlling the opening and closing of the faucet solenoid valve. For example, when a user covers the sensing window, the TOF sensing chip 4 detects an object and generates a first object detection sensing signal. The control chip 17 receives this first object detection sensing signal and generates a first control signal based on it. This first control signal is then sent to the faucet solenoid valve via the solenoid valve control line 14, thereby controlling the opening of the faucet solenoid valve. When the user covers the sensing window again, the TOF sensing chip 4 detects an object again and generates a second object detection sensing signal. The control chip 17 receives this second object detection sensing signal and generates a second control signal based on it. This second control signal is then sent to the faucet solenoid valve via the solenoid valve control line 14, thereby controlling the closing of the faucet solenoid valve.

[0042] In a preferred embodiment, the control module 24 of the faucet sensor module further includes a battery connection cable 16. The control chip 17 is electrically connected to the battery connection cable 16 and, through the battery connection cable 16, is electrically connected to a power supply battery. The power supply battery is housed in a separate battery compartment. The power supply battery can supply power to the control module 24 via the battery connection cable 16.

[0043] In a preferred embodiment, the control module 24 of the faucet sensor module further includes a power adapter connection cable 13. The control chip 17 is electrically connected to the power adapter connection cable 13 and is electrically connected to a power supply through the power adapter connection cable 13. The power supply can supply power to the control module 24 through the power adapter connection cable 13.

[0044] In addition, the control module 24 also includes a control box 12, within which the control chip 17 is housed. The gap between the control chip 17 and the control box 12 is sealed with adhesive to prevent water leakage from affecting the chip's operation. The control box 12 is a completely sealed structure. An external positioning structure 23 is provided on the control box 12 for positioning with a corresponding structure on the faucet.

[0045] The faucet sensor module can be installed in a suitable location inside the faucet housing 20. In one embodiment, the sensing part of the faucet sensor module is located near the faucet spout 18, with the sensing window of the housing exposed externally near the spout 18. The housing can be secured inside the faucet by positioning ribs. A plastic fixing block 19 is provided inside the faucet and above the housing to further secure the housing. The control module 24 is located near the solenoid valve module 25 inside the faucet to facilitate connection between the solenoid valve control line in the control module and the solenoid valve module. The sensing part and the control module are connected via a TOF signal line extending inside the faucet.

[0046] Although embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for this utility model. Other modifications can be readily implemented by those skilled in the art. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and examples shown and described herein.
