Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment technology, and in particular to a water faucet and a water purifier and hot water unit having the same. Background Technology

[0002] With the development of technology, smart faucets are becoming increasingly widely used in homes and public bathrooms due to their convenient operation and advantages such as water saving and hygiene. These smart faucets usually require a built-in control circuit board to realize their intelligent functions.

[0003] In current common smart faucet designs, the control circuit board is either placed inside the faucet handle or installed in the base behind the faucet body or under the countertop. The former design tends to result in an excessively large and heavy handle, affecting the feel and aesthetics of operation. Furthermore, the limited internal space of the handle significantly restricts the size of the circuit board and heat dissipation. While the latter design avoids the problem of a bulky handle, it significantly increases the size of the faucet base, affecting the overall aesthetics and installation flexibility. In addition, the connection lines between the circuit board and the operating components need to pass through the faucet body or base, increasing the complexity of internal wiring and potential leakage risks. Moreover, the internal space of a traditional faucet body is mainly used for water passage. When introducing smart control functions, how to efficiently and compactly utilize the limited internal space of the faucet body, while reasonably separating the water passage and electrical circuit to avoid mutual interference, is a technical problem that urgently needs to be solved.

Detailed Implementation

[0037] The present invention will be further described below with reference to the accompanying drawings.

[0038] A type of faucet, such as Figure 1-6As shown, the faucet includes a faucet body 1, which includes a horizontal section 11. A control circuit board 2 is fixedly installed inside the horizontal section 11. The length direction of the control circuit board 2 extends parallel to the axis of the horizontal section 11. A water inlet pipe 3 is installed below the control circuit board 2. The control circuit board 2 and the water inlet pipe 3 are arranged side by side vertically inside the horizontal section 11, forming a circuit layer 111 where the control circuit board 2 is located and a water channel layer 112 where the water inlet pipe 3 is located. An operating handle 4 is provided on the top of the horizontal section 11, and the operating handle 4 is electrically connected to the control circuit board 2. The control circuit board 2 is a long and narrow rectangular plate that extends and is fixed along the top of the inner wall of the horizontal section 11. The control circuit board 2 and the water inlet pipe 3 form a vertically layered structure, with the circuit layer 111 on the upper layer and the water channel layer 112 on the lower layer. The layout is reasonable, and the circuit and water channel do not interfere with each other, which is convenient for maintenance. The operating handle 4 is set at the top of the horizontal section 11 and close to the control circuit board 2, which enables the signal line of the operating handle 4 to be connected to the control circuit board 2 over a short distance without passing through the water channel, which ensures the safety of the circuit and facilitates maintenance.

[0039] Preferably, the operating handle 4 includes a fixing plate 41 fixed on the horizontal section 11 and a screw cap 42 sleeved on the fixing plate 41. The fixing plate 41 is provided with a positioning plate 43, and the positioning plate 43 is provided with a plurality of positioning grooves 44. The screw cap 42 is connected to a positioning element 45 that is positioned and engaged with the positioning grooves 44. The fixing plate 41 is connected to the faucet body 1 by bolts, and the positioning plate 43 is connected to the fixing plate 41 by bolts. A limiting ring 431 is fixedly provided circumferentially at the vertical extension of the positioning plate 43. The cap 42 is located between the limiting ring 431 and the positioning plate 43, forming a limit on the upper and lower positions of the cap 42 to prevent the cap 42 from falling off. The positioning groove 44 is circumferentially arranged on the positioning plate 43, and the positioning grooves 44 are equally spaced. The positioning element 45 is positioned corresponding to the positioning groove 44, and the contour of the positioning element 45 matches the contour of the positioning groove 44. When the cap 42 is rotated, the positioning element 45 moves in a circle along each positioning groove 44. When the positioning element 45 slides into each positioning groove 44, it will make a "click" sound to indicate to the operator that the positioning has been completed, which increases the feel and completes the precise positioning of the cap 42.

[0040] Preferably, the positioning member 45 is a hollow protrusion, and a first spring 46 is provided inside the hollow protrusion. The positioning groove 44 is adapted to the contour of the hollow protrusion, and the first spring 46 is used to provide the hollow protrusion with the positioning groove 44. The hollow protrusion is composed of a spherical portion 451 and a cylindrical extension 452 extending vertically upward from the spherical portion 451. The contour of the positioning groove 44 is adapted to the contour of the spherical portion 451. When the hollow protrusion slides between the positioning grooves 44, the cylindrical extension 452 provides vertical support to the spherical portion 451, preventing the spherical portion 451 from deforming and coming out when making arc movements. The cylindrical extension 452 makes the spherical portion 451 more stable when sliding on the positioning plate 43. In addition, since the first spring 46 is set inside the cylindrical extension 452, the first spring 46 is not easy to come out under the blocking effect of the cylindrical extension 452, and the first spring 46 is prevented from deforming when the spherical portion 451 makes arc movements, thus improving the stability of the first spring 46.

[0041] Preferably, the cap 42 is fixedly provided with an arc-shaped protrusion 421 that abuts against the positioning disk 43. The cap 42 slides on the end face of the positioning disk 43 via the arc-shaped protrusion 421. The arc-shaped protrusion 421 can be a hemisphere or an arc-shaped ring. The contact area between the cap 42 and the positioning disk 43 is reduced by the arc-shaped protrusion 421, thereby reducing the friction between the cap 42 and the positioning disk 43 during rotation.

[0042] Preferably, a control plate 47 is fixedly mounted on the fixing plate 41, located below the positioning disk 43. A Hall sensor is mounted on the control plate 47, and a magnet 422 is mounted on the screw cap 42. When the screw cap 42 rotates, the Hall sensor determines the rotational position of the screw cap 42 by detecting changes in the magnetic field of the magnet 422. The Hall sensor contains at least one Hall element. The Hall sensor determines the angular position of the screw cap 42 by detecting changes in the magnetic field. This is the basic principle of the Hall effect, which will not be elaborated further here. When the screw cap 42 rotates, it causes the magnet 422 to rotate, and the relative position between the magnet and the Hall sensor changes, resulting in a change in the magnetic field strength detected by the Hall sensor. Based on the different voltage signals output by the Hall sensor, the angular position of the screw cap 42 is determined, achieving precise angular positioning of the screw cap 42.

[0043] Preferably, an LED bead 471 is circumferentially arranged below the control plate 47, and a light-transmitting surface 411 is formed on the fixing plate 41 corresponding to the light-emitting end of the LED bead 471. There is an upper and lower gap between the screw cap 42 and the control plate 47. The light emitted by the LED bead 471 passes through the light-transmitting surface 411 of the fixing plate 41 and exits through the gap between the screw cap 42 and the control plate 47, forming an ambient light around the bottom of the screw cap 42 to indicate the position of the operating handle 4. This allows the user to quickly find the operating handle 4 in dim lighting conditions, making it more user-friendly.

[0044] Preferably, a display panel 48 is disposed above the screw cap 42, and a light-emitting surface 472 corresponding to the display panel 48 is disposed on the end face of the control plate 47. The display panel 48 is used to transmit light emitted from the light-emitting surface 472. A hollow support column 7 is disposed between the display panel 48 and the control plate 47. The bottom of the hollow support column 7 corresponds to the light-emitting surface 472, and the hollow support column 7 forms a light-emitting channel from the light-emitting surface 472 to the display panel 48. The light emitted from the light-emitting surface 472 is guided towards the display panel 48 by the light-guiding effect of the hollow support column 7. By setting the hollow support column 7, both the display panel 48 and the control plate 47 are supported, and the light-emitting surface 472 is guided. As a preferred embodiment, a second spring 8 is also disposed on the outer periphery of the hollow support column 7. The second spring 8 is in a compressed state between the display panel 48 and the control plate 47 to improve the supporting effect of the hollow support column 7.

[0045] Preferably, the faucet body 1 includes a water outlet 5 located at the end of the horizontal section 11, and the water inlet pipe 3 includes a first water inlet pipe 313 and a second water inlet pipe 323 that are independent of each other. The first water inlet pipe 313 and the second water inlet pipe 323 extend to the water outlet 5, forming an independent outer water outlet cavity 311 and an inner water outlet cavity 321. The water outlet directions of the outer water outlet cavity 311 and the inner water outlet cavity 321 are coaxial and parallel. The first water inlet pipe 313 and the second water inlet pipe 323 can be cold water pipe and hot water pipe, respectively. The water outlet 5 is a hollow annular cylinder, forming an outer water outlet cavity 311 and an inner water outlet cavity 321. The outer water outlet cavity 311 and the inner water outlet cavity 321 are respectively connected to the first water inlet pipe 313 and the second water inlet pipe 323, realizing the separate delivery of cold and hot water flows and ensuring that the temperature of the water outlet 5 remains stable under the stratification effect.

[0046] Preferably, an exhaust pipe 6 is provided near the water inlet pipe 3, and the exhaust port 61 of the exhaust pipe 6 extends to the outside of the faucet body 1. By providing the exhaust pipe 6, the high-temperature steam generated by heating the water is discharged outside the faucet body 1 through the exhaust port 61 of the exhaust pipe 6, avoiding the obstruction of water flow by gas and ensuring uneven water output.

[0047] This utility model also provides an integrated water purifier and hot water heater, which has the water faucet as described above. By installing a water faucet on the integrated water purifier and hot water heater, an intelligent function integrating water purification and hot water heating is realized.
