Description

Technical Field

[0001] This utility model relates to the field of faucet technology, specifically to a sensor-controlled temperature faucet. Background Technology

[0002] With increasing awareness of hygiene and water conservation, sensor-operated faucets are becoming more widely used in public places and homes. Traditional sensor-operated faucets mainly use infrared sensing technology to achieve automatic water dispensing and shutting off. Their working principle is that when a user's hand or other object approaches the faucet's sensing area, the sensor detects a signal and controls the solenoid valve to open, allowing water to flow automatically. When the hand or object leaves the sensing area, the sensor stops outputting signals, and the valve closes, thus achieving water conservation and hygiene.

[0003] However, traditional sensor-operated faucets have a significant limitation: they lack temperature adjustment capabilities. Typically, these faucets can only dispense water at one temperature, usually room temperature or a pre-set temperature. In practice, users often need to adjust the water temperature according to different scenarios and needs. For example, warm water is preferred for handwashing in winter, while cold water may be preferred in summer. Furthermore, in scenarios like the kitchen, users may need to switch between hot and cold water to meet different cooking and cleaning needs. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is intended to aid in understanding this utility model, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] Reference Figures 1 to 5 As shown, a sensor-controlled temperature-regulating faucet includes a faucet housing 1, a mounting base 2 disposed within the faucet housing 1, the mounting base 2 having a cold water inlet 21, a hot water inlet 22, a mixing chamber 23 communicating with the cold water inlet 21 and the hot water inlet 22, a water passage chamber 24 communicating with the mixing chamber 23, and a water outlet pipe 25 communicating with the water passage chamber 24. The faucet housing 1 has a water outlet chamber 11, and the water outlet pipe 25 communicates with the water outlet chamber 11. It also includes a solenoid valve 3 and a sensor probe 4 for controlling the opening or closing of the solenoid valve 3. The water passage chamber 24 has a stepped portion 241. The solenoid valve 3 is provided with a piston 31 that blocks the stepped portion 241; it also includes a temperature regulating rod 5, which includes a temperature regulating part 51 disposed in the mixing chamber 23 and a handle part 52 extending out of the faucet housing 1. The temperature regulating part 51 is provided with a hot water through hole 511 communicating with the hot water interface 22 and a cold water through hole 512 communicating with the cold water interface 21. The cold water through hole 512 and the hot water through hole 511 are arranged non-parallel to each other. The temperature regulating part 51 is also provided with a notch surface 513, through which the mixing chamber 23 and the water passage chamber 24 are kept unobstructed.

[0028] Specifically, it also includes a cold water pipe 6 connected to the cold water interface 21 via a threaded seal, and a hot water pipe 7 connected to the hot water interface 22 via a threaded seal. Hot and cold water are supplied through the hot water pipe 7 and the cold water pipe 6. Because the cold water through-hole 512 and the hot water through-hole 511 are not arranged parallel to each other on their central axes, when the user rotates the temperature control rod 5 via the handle 52, the communication area between the hot water through-hole 511 and the hot water interface 22 changes, and the communication area between the cold water through-hole 512 and the cold water interface 21 changes, thereby changing the ratio of hot and cold water intake and achieving water temperature regulation. When the sensor probe 4 detects the user, the piston 31 of the solenoid valve 3 moves away from the step 241, opening the water passage chamber 24. Then, water flows through the water outlet pipe 25 into the water outlet chamber 11 of the faucet housing 1, finally allowing water to flow from the faucet.

[0029] The mounting base 2 is integrally formed. The water outlet pipe 25 is arranged in an L-shape, with the horizontal section of the water outlet pipe 25 parallel and spaced apart from the mixing chamber 23. The water passage chamber 24 is located above the mixing chamber 23, and the interior of the water passage chamber 24 has a stepped portion 241. The solenoid valve 3 is installed on the upper surface of the water passage chamber 24, and the vertical section of the water outlet pipe 25 is arranged parallel to the water passage chamber 24. Through the above arrangement, and by integrally casting the cold water interface 21, hot water interface 22, mixing chamber 23, water passage chamber 24, and water outlet pipe 25, as well as the positional relationship of the vertical and horizontal sections of the water outlet pipe 25, the volume of the mounting base 2 is minimized, thereby reducing the external dimensions of the faucet housing 1 and occupying less space during installation and use. Furthermore, the one-piece molded mounting base 2 eliminates the need for additional assembly work, which not only reduces production steps but also improves production efficiency and product quality stability.

[0030] The mounting base 2 also includes a base plate 26, the upper end of which is provided with a slot 27. A nut 271 is provided in the slot 27. It also includes a mounting rod 8 and a mounting plate 9. The mounting plate 9 is disposed at the lower end of the countertop of the basin. The mounting rod 8 supports the mounting plate 9 and is threadedly connected to the nut 271. The nut 271 is pre-embedded laterally in the slot 27. When assembling the temperature-controlled faucet onto the countertop of the basin to be installed, the faucet housing 1 is first placed on the countertop of the basin. Then, the mounting rod 8 passes through the mounting plate 9 from bottom to top and is connected to the nut 271. The mounting plate 9 increases the contact area with the countertop of the basin, ensuring that the temperature-controlled faucet is stably connected to the countertop of the basin.

[0031] The hot water through-hole 511 and the cold water through-hole 512 are arranged vertically, thereby maximizing the change in the ratio of hot water to cold water intake during the rotation of the temperature regulating rod 5, and achieving rapid adjustment of the outlet water temperature.

[0032] The temperature regulating rod 5 includes sealing rings 514 sleeved on both ends of the temperature regulating part 51. The sealing rings 514 seal against the mixing chamber 23 and prevent water from leaking out of the mounting base 2.

[0033] The temperature regulating rod 5 also includes a retaining spring 53 sleeved on the temperature regulating part 51, the retaining spring 53 abutting against the outer end face of the mounting base 2. The temperature regulating rod 5 also includes a screw 54 for connecting the handle part 52 and the temperature regulating part 51. The above structure enables the assembly of the temperature regulating rod 5 and the mounting base 2.

[0034] Both the cold water inlet 21 and the hot water inlet 22 are pre-embedded with one-way valves 61, through which the water in the mixing chamber 23 of the one-way valve 61 flows back to the cold water pipe 6 or the hot water pipe 7.

[0035] The sensor 4 includes a sensor box 41, a decorative cover 42 disposed at the front end of the sensor box 41, and a sealing baffle 43 sandwiched between the decorative cover 42 and the faucet housing 1. The sealing baffle 43 may be made of rubber. An infrared sensor integrating transmission and reception may be installed in the sensor box 41. The outer peripheral surface of the decorative cover 42 is flush with the outer peripheral surface of the faucet housing 1 to increase the aesthetics of the product. The sealing baffle 43 prevents external debris such as water flow and dust from seeping into the interior of the faucet housing 1 along the gap.
