[0051] The instant hot water faucet is equipped with a screen-lighting sensor 4 and a fingerprint reader 8. The screen-lighting sensor 4 ensures that the faucet's screen 5 only lights up when someone approaches or operates it, and automatically turns off at other times. The display can be activated without manually operating buttons or touching the screen. Furthermore, through the cooperation of the fingerprint reader 8 and the control panel 9, the control panel 9 controls the heating element 1 to heat the water to the preset water temperature and then outputs the corresponding water volume. The user can personalize the water temperature and water volume settings to meet the different needs of family members, improving the convenience and intelligent experience of use.

[0052] Specifically, the lower end of the first connecting sleeve 212 is provided with a connecting platform 201, and the connecting platform 201 is provided with a through hole 202; the upper end of the second connecting sleeve 222 is provided with a mounting base 203, and the mounting base 203 is provided with a screw hole that matches the position of the through hole 202; the lower end of the first connecting sleeve 212 is embedded into the upper end of the second connecting sleeve 222, and the first connecting sleeve 212 and the second connecting sleeve 222 are detachably connected by the cooperation of screws, through hole 202 and screw hole.

[0053] In one specific embodiment of this utility model, the first connecting sleeve 212 and the second connecting sleeve 222 are connected by screws. The sidewall of the first connecting sleeve 212 is recessed inward, forming a connecting platform 201 near the lower end of the first connecting sleeve 212; the upper end of the second connecting sleeve 222 is provided with a mounting seat 203 that matches the position and number of the connecting platforms 201. The screw passes through the through hole 202 of the connecting platform 201 and is threadedly connected to the screw hole of the mounting seat 203, so that the connecting platform 201 is tightly pressed against the mounting seat 203, thereby realizing the detachable connection between the first connecting sleeve 212 and the second connecting sleeve 222. Specifically, the front side of the first connecting sleeve 212 is provided with two connecting platforms 201, and the upper end of the second connecting sleeve 222 is provided with two mounting seats 203. The position and number of the connecting platforms 201 and the mounting seats 203 can be adjusted according to the existing situation, and are not limited here.

[0054] Specifically, the heating element 1 includes a heating element 11, a first terminal 12, and a second terminal 13; the first terminal 12 and the second terminal 13 are electrically connected to the heating element 11, one end of the heating element 11 is connected to the water outlet 214, and the other end of the heating element 11 is connected to the water inlet 223.

[0055] The heating element 1 can refer to the existing heating element structure of water purifiers. The first terminal 12 and the second terminal 13 are both interfaces for power connection. The first terminal 12 and the second terminal 13 are both connected to the power cord to transmit the power energy from the external power source to the heating element of the heating element 11, thereby starting the heating process.

[0056] Furthermore, the heating element 1 also includes heat insulation cotton 14, which is sleeved on the outer periphery of the heating element 11, and the heat insulation cotton 14 is provided with heat insulation cotton clearance holes that are adapted to the positions of the first terminal 12 and the second terminal 13, and the first terminal 12 and the second terminal 13 both pass through the heat insulation cotton clearance holes at the corresponding positions.

[0057] The insulation cotton 14 reduces heat loss and prevents heat from dissipating into the air through the outer wall of the heating element 11 during the heating process, thereby improving the overall thermal efficiency of the heating system. With the insulation cotton 14, more heat can be concentrated in the water to be heated, making the heating process more efficient and resulting in significant energy savings.

[0058] In addition, the heat insulation cotton 14 can effectively isolate the heat of the external environment from the heating element 11, reducing the risk of burns caused by the user coming into contact with the overheated surface during operation. It can also prevent other surrounding components from aging or deforming due to excessive heat, thus extending their service life.

[0059] The insulation cotton clearance hole provides space for the first terminal 12 and the second terminal 13, preventing the insulation cotton 14 from interfering with the first terminal 12 or the second terminal 13, which would prevent the first terminal 12 or the second terminal 13 from being connected to the external power source.

[0060] Furthermore, the first connecting sleeve 212 has a first terminal clearance hole on one side, and the second connecting sleeve 222 has a second terminal clearance hole on one side; the first terminal 12 passes through the first terminal clearance hole, and the second terminal 13 passes through the second terminal clearance hole.

[0061] The first connecting sleeve 212 has a first wire groove and a third wire groove on its other side, and the second connecting sleeve 222 has a second wire groove and a fourth wire groove on its other side. The first wire groove and the second wire groove cooperate to form a low-voltage wire groove 204. The low-voltage wire groove 204 is used to house the data transmission line of the heating element. The third wire groove and the fourth wire groove cooperate to form a signal wire groove 205. The signal wire groove 205 is used to house the sensor circuit.

[0062] The power supply line for the heating module of the instant hot water faucet is connected to the first terminal 12 and the second terminal 13, and is a high-voltage wire, while the control circuit for controlling the heating element and the data transmission line for the heating element to send data to the control panel are low-voltage wires. This structure, separating the high-voltage and low-voltage wires, reduces electromagnetic interference, ensures stable signal transmission, and prevents malfunctions or signal loss. Furthermore, during maintenance, technicians can more clearly identify and locate the source of the problem, reducing the difficulty of troubleshooting.

[0063] Similarly, separating the control circuit for the heating element and the data transmission line for the heating element to send data to the control panel makes it easier for maintenance personnel to identify and locate the source of the problem, further reducing the difficulty of troubleshooting.

[0064] Specifically, the rotary arm 6 is provided with an upward-facing receiving groove, the control box 7 includes a cover plate 71 and a box body 72, the box body 72 is installed in the receiving groove; the cover plate 71 is connected to the box body 72, and the cover plate 71 covers the opening of the receiving groove; the observation area 70 is provided on the cover plate 71.

[0065] The receiving tank is also equipped with a drainage channel. One end of the drainage channel is connected to the water outlet of the heating element 1, and the other end is connected to the water outlet 61. The cover plate 71 is connected to the box body 72 and covers the opening of the receiving tank, so that the rotating arm 6 and the control box 7 cooperate to form a whole, enhancing the sealing and preventing moisture from entering the control box 7 and affecting the control panel 9. The observation area 70 is used to display the image on the screen 5.

[0066] Optionally, the control box 7 is also provided with a voice recognition element 73; the voice recognition element 73 is electrically connected to the control panel 9, and the voice recognition element 73 and the control panel 9 work together to control the heating element 1 to output water at the corresponding temperature.

[0067] The voice recognition element 73 can refer to existing voice recognition modules. Based on the voice commands recognized by the voice recognition element 73, the control panel 9 controls the heating element 1 to heat the water to the preset water temperature and then outputs the water.

[0068] With the above structure, users do not need to manually adjust the water purifier. They only need to issue a command, and the hot water tap will respond according to the voice command. This reduces tedious operations and is more user-friendly for the elderly with lower technical literacy, avoiding confusion or misoperation caused by the complexity of operation.

[0069] Optionally, the rotating arm 6 is provided with a water level monitoring element 62; the water level monitoring element 62 is located on one side of the water outlet 61; the water level monitoring element 62 is electrically connected to the control panel 9 and is used to determine the water level of the cup.

[0070] The water level monitoring element 62 can refer to existing water level monitoring sensors such as infrared sensor probes in water purifier faucets. The water level monitoring element 62 monitors the water level in the container. When the water level in the container reaches the predetermined value, the water level monitoring element 62 sends an electrical signal to the control panel 9, causing the control panel 9 to control the internal components to stop water dispensing. This avoids water overflow caused by user negligence or carelessness, ensures the cleanliness of the area near the water purifier, and avoids excessive water supply and waste, thus helping families save water.

[0071] Optionally, the control box 7 is further provided with an NFC identification element 74; the NFC identification element 74 is electrically connected to the control panel 9 and is used to identify water containers with NFC.

[0072] The control panel 9 includes a recording module that records the entered NFC tags and stores the water temperature and volume recorded by each tag. When a water container with the corresponding NFC tag is detected again, the control panel 9 controls the heating element 1 to heat the water to the preset temperature and then outputs the preset volume of water. This structure allows for personalized water temperature and volume settings based on different NFC tag water containers, meeting the diverse needs of family members and providing a more comfortable water experience.

[0073] This utility model also provides a water purifier that uses the above-mentioned instant hot water faucet.
