[0001] This utility model relates to the field of bathroom technology, and in particular to a display device and a shower faucet for use in a shower faucet. Background Technology

[0002] Currently, shower heads with digital displays are gaining popularity among users because they can show key information such as water temperature, water volume, and usage time, helping users to accurately control their bathing environment, avoid discomfort caused by sudden changes in water temperature, and improve bathing comfort.

[0003] Conventional showerheads with digital displays typically require a hydroelectric generator to power the screen. However, hydroelectric generators are complex in structure, expensive to manufacture, and bulky. Sufficient space needs to be reserved for the internal piping of the showerhead during installation, increasing the overall size of the showerhead and limiting its design flexibility. Furthermore, this design is difficult to adapt to compact showerheads, limiting the applicability of the digital display function.

[0004] Therefore, there is an urgent need for a display device and a shower faucet for use in shower faucets to solve the above problems. Utility Model Content

[0005] Based on the above problems, the purpose of this utility model is to provide a display device and a shower faucet for a shower faucet, which can simplify the structure of the display device, reduce manufacturing costs, reduce space occupation, and improve the flexibility of use of the display device.

[0010] The Hall effect sensor is electrically connected to the control circuit board.

[0011] A sensing component is disposed within the main pipeline and opposite to the Hall element; the sensing component includes a housing and a Hall rotor rotatably disposed within the housing. When water flows through the main pipeline, the water flow can pass through the housing and drive the Hall rotor to rotate within the housing, so that the Hall rotor generates a magnetic field. The Hall element can illuminate the display screen of the control circuit board under the action of the magnetic field of the Hall rotor.

[0012] The power module is electrically connected to the display screen, the control circuit board, and the Hall effect sensor, and is used to supply power to the display screen, the control circuit board, and the Hall effect sensor.

[0013] As an optional embodiment of the display device for a shower faucet of this utility model, the two ends of the housing are respectively provided with a water inlet and a water outlet, and at least one of the water inlet and the water outlet is an inclined hole.

[0014] As an optional embodiment of the display device for a shower faucet according to this utility model, both ends of the housing are provided with rotating holes, and the Hall rotor includes a rotating shaft, with both ends of the rotating shaft respectively corresponding to and rotating in cooperation with the two rotating holes.

[0015] As an optional embodiment of the display device for a shower faucet according to this utility model, the bottom of the rotating hole is provided with a protruding structure, the protruding surface of the protruding structure is an outwardly convex arc surface, and the outwardly convex arc surface can movably contact the end of the rotating shaft.

[0016] As an optional embodiment of the display device for a shower faucet according to this utility model, the housing includes a first cylindrical part and a second cylindrical part that are nested together. One of the first cylindrical part and the second cylindrical part is provided with a slot, and the other is provided with a snap-fit ​​protrusion. The snap-fit ​​protrusion snaps into the slot.

[0017] As an optional embodiment of the display device for a shower faucet according to this utility model, the Hall rotor includes a rotating shaft and multiple magnetic blades, with the multiple magnetic blades arranged circumferentially at intervals on the rotating shaft.

[0018] As an optional embodiment of the display device for a shower faucet according to the present invention, the Hall rotor includes a rotating shaft, a magnet and a guide vane. The guide vane and the magnet are spaced apart on the rotating shaft along the water flow direction, and multiple magnets are spaced apart on the rotating shaft circumferentially. Multiple guide vanes are spaced apart on the rotating shaft circumferentially, and each guide vane is inclined relative to the rotating shaft.

[0019] As an optional embodiment of the display device for a shower faucet according to this utility model, the Hall component includes a Hall sensor;

[0020] And / or, the power module includes a battery, or the power module includes a power adapter.

[0021] On the other hand, a shower faucet is provided, including a mounting housing, a valve body assembly, and a display device for the shower faucet as described above, wherein the valve body assembly is disposed within the mounting housing, the display screen of the display device is disposed within the mounting housing, the valve body assembly includes a main pipe, and the sensing component of the display device is disposed within the main pipe.

[0022] As an optional solution for the shower faucet of this utility model, the main pipeline includes a first pipe section and a second pipe section that can be detachably connected. The first pipe section is provided with a receiving groove, and the sensing component is located in the receiving groove.

[0023] The beneficial effects of this utility model are as follows:

[0024] This utility model provides a display device and a shower faucet for a showerhead. When water flows through the main pipe of the valve assembly, the water flows through the housing of the sensing component. During this process, the water flow impacts the Hall rotor inside the housing, causing the Hall rotor to rotate and generate a magnetic field. Since the Hall rotor is opposite to the Hall element, and the Hall element is electrically connected to the control circuit board, the dynamic magnetic field generated by the rotating Hall rotor will produce a Hall effect with the Hall element, triggering the Hall element to start and output a corresponding signal to the control circuit board. The control circuit board then conducts the circuit of the display screen according to the signal, causing the display screen to light up. When the water flow in the main pipe stops, the Hall rotor stops rotating, the magnetic field disappears, the Hall element stops outputting signals, and the control circuit board disconnects the circuit of the display screen, causing the display screen to turn off. That is, this display device can automatically control the display screen to light up or turn off according to the water flow in the main pipe of the shower faucet, making it convenient for users to observe the display content or operate the display screen when using the shower faucet.

[0025] Because a separate power module supplies power to the display screen, control circuit board, Hall effect sensors, etc., there is no need for a separate hydroelectric generator, which simplifies the structure of the display device and reduces manufacturing costs. Furthermore, eliminating the hydroelectric generator means that the sensing components only need to be installed within the main piping, reducing the number of components installed in the shower faucet piping and minimizing space requirements. This allows the display device to be used in compact shower faucets and other shower head products, increasing its flexibility and facilitating the miniaturization of shower faucets and other shower head products.

[0048] Example 1

[0049] like Figures 1 to 4 As shown, this embodiment provides a display device for a shower faucet, which simplifies the structure of the display device, reduces manufacturing costs, minimizes space occupation, and improves the flexibility of use of the display device.

[0050] See Figure 1 The shower faucet includes a valve body assembly 20, which includes a main pipe 201. (See also...) Figure 2 and Figure 3 The display device includes a display screen 1, a control circuit board 2, a Hall effect sensor 3, a sensing component 4, and a power module 5. The display screen 1 displays information such as water temperature, water volume, and usage time. The control circuit board 2 is electrically connected to the display screen 1, and the Hall effect sensor 3 is also electrically connected to the control circuit board 2. The sensing component 4 is located within the main pipe 201 and is opposite to the Hall effect sensor 3. The sensing component 4 includes a housing 41 and a Hall effect rotor 42 rotatably disposed within the housing 41. When water flows through the main pipe 201, the water flow passes through the housing 41 and drives the Hall effect rotor 42 to rotate within the housing 41, causing the Hall effect rotor 42 to generate a magnetic field. Under the influence of the magnetic field of the Hall effect rotor 42, the Hall effect sensor 3 can illuminate the display screen 1 on the control circuit board 2. The power module 5 is electrically connected to the display screen 1, the control circuit board 2, and the Hall effect sensor 3, and is used to supply power to these components.

[0051] The sensing component 4 and the Hall component 3 are opposite each other. They can be directly opposite each other or slightly misaligned, as long as the Hall component 3 can generate a Hall effect with the Hall rotor 42.

[0052] The display device for a shower faucet provided in this embodiment shows that when water flows through the main pipe 201 of the valve body assembly 20 ( Figure 2 The dotted arrow in the diagram indicates the direction of water flow. Water flows through the housing 41 of the sensing component 4. During this process, the water flow impacts the Hall rotor 42 inside the housing 41, causing the Hall rotor 42 to rotate and generate a magnetic field. Since the Hall rotor 42 is opposite to the Hall element 3, and the Hall element 3 is electrically connected to the control circuit board 2, the dynamic magnetic field generated when the Hall rotor 42 rotates will produce a Hall effect with the Hall element 3, triggering the Hall element 3 to start and output a corresponding signal to the control circuit board 2. The control circuit board 2 then conducts the circuit of the display screen 1 according to the signal, causing the display screen 1 to light up. When the water flow in the main pipe 201 stops, the Hall rotor 42 stops rotating, the magnetic field disappears, the Hall element 3 stops outputting signals, and the control circuit board 2 disconnects the circuit of the display screen 1, causing the display screen 1 to turn off. That is, this display device can automatically control the display screen 1 to light up or turn off according to the water flow interruption in the main pipe 201 of the shower faucet, making it convenient for users to observe the display content or operate the display screen 1 when using the shower faucet.

[0053] Since a separate power module 5 supplies power to the display screen 1, control circuit board 2, Hall effect sensor 3, etc., there is no need to set up a hydroelectric generator for power supply, which simplifies the structure of the display device and reduces manufacturing costs. At the same time, by eliminating the hydroelectric generator, only the sensing component 4 needs to be installed in the main pipe 201, which reduces the number of components installed in the shower faucet pipe and reduces space occupation. This allows the display device to be used in compact shower faucets and other shower products, improving the flexibility of the display device and facilitating the miniaturization design of shower faucets and other shower products.

[0054] Optionally, the Hall element 3 includes a Hall sensor. When the magnetic field strength generated by the rotation of the Hall rotor 42 reaches the trigger threshold of the Hall sensor, the charge carriers inside the Hall sensor are subjected to the Lorentz force, generating a Hall voltage, which changes its output state (e.g., from a high level to a low level, or vice versa). The output signal of the Hall sensor is connected to the control circuit (such as an MCU, MOSFET, or relay) on the control circuit board 2. After the control circuit board 2 detects the change in the Hall signal, it closes the loop, energizing the display screen 1 and lighting it up.

[0055] In some embodiments, the Hall element 3 can be a Hall switch, which has a simple and clear output signal and low power consumption.

[0056] In some embodiments, the Hall element 3 can also be a linear Hall sensor, which has high accuracy and linearity and can meet the requirements of high-precision detection.

[0057] In some embodiments, the power module 5 includes a battery, which can be a rechargeable battery or a dry cell battery, as long as it can meet the power supply requirements.

[0058] In some embodiments, the power module 5 may also include a power adapter, which is directly plugged into a power socket to supply power to the display screen 1, the control circuit board 2, and the Hall effect sensor 3.

[0059] See Figure 4 , Figure 5 and Figure 6 The housing 41 has an inlet hole 4111 and an outlet hole 4121 at its two ends, respectively, and at least one of the inlet hole 4111 and the outlet hole 4121 is an inclined hole. When water flows into the housing 41, the inclined hole can guide the water flow to generate a vortex, thereby driving the Hall rotor 42 to rotate.

[0060] In this embodiment, the water inlet 4111 of the housing 41 is an inclined hole. When water flows through the inclined hole, it can flow obliquely towards the Hall rotor 42, generating a rotational torque on the Hall rotor 42 and driving the Hall rotor 42 to rotate within the housing 41. Optionally, multiple water inlets 4111 are arranged circumferentially on the housing 41, and the multiple water inlets 4111 are inclined in the same direction to ensure that there is sufficient water flow impact force acting on the Hall rotor 42, ensuring that the Hall rotor 42 rotates smoothly.

[0061] For example, such as Figure 5 As shown, five water inlets 4111 are provided, and the five water inlets 4111 are arranged in a ring with the rotation axis of the Hall rotor 42 as the center. Of course, in other embodiments, the number of water inlets 4111 can be increased or decreased according to actual needs, and is not limited to the number listed above.

[0062] In some alternative embodiments, the water outlet 4121 on the housing 41 can also be designed as an inclined hole, so that when the water flows out of the housing 41, a rotating water flow can be generated in the housing 41, thereby driving the Hall rotor 42 to rotate inside the housing 41.

[0063] See Figure 2 and Figure 4 The housing 41 has rotating holes 413 at both ends. The Hall rotor 42 includes a rotating shaft 421, with each end of the shaft 421 corresponding to one of the two rotating holes 413 for rotational engagement, so that the Hall rotor 42 can rotate smoothly relative to the housing 41 under the impact of water flow. The engagement between the rotating shaft 421 and the rotating holes 413 also restricts the Hall rotor 42 to rotate only circumferentially within the housing 41, preventing axial movement and ensuring the rotational stability of the Hall rotor 42.

[0064] See Figure 2 , Figure 5 and Figure 6 The bottom of the rotating hole 413 is provided with a protruding structure 4131. The protruding surface of the protruding structure 4131 is an outwardly convex arc-shaped surface, which can make movable contact with the end of the rotating shaft 421. When the Hall rotor 42 rotates, the end face of the rotating shaft 421 makes movable contact with the outwardly convex arc-shaped surface, which can reduce the rotational resistance of the rotating shaft 421 and improve the rotational efficiency of the Hall rotor 42.

[0065] See Figure 2 and Figure 4 The Hall rotor 42 includes a rotating shaft 421 and multiple magnetic blades 422, which are circumferentially spaced on the rotating shaft 421. During the rotation of the Hall rotor 42, the multiple magnetic blades 422 take turns approaching the Hall component 3, resulting in a higher frequency of magnetic field changes, thereby reducing signal delay and improving real-time detection performance.

[0066] Optionally, the magnetic blades 422 can be made of magnets, or magnets can be embedded in non-magnetic materials to enable the magnetic blades 422 to generate a magnetic field. Exemplarily, four magnetic blades 422 are provided, arranged in a ring around the axis of the rotation shaft 421. In other embodiments, the number of magnetic blades 422 can be adaptively increased or decreased as needed.

[0067] See Figure 2 and Figure 4 The housing 41 includes a first cylindrical portion 411 and a second cylindrical portion 412 that are nested together. One of the first cylindrical portion 411 and the second cylindrical portion 412 is provided with a slot 4122, and the other is provided with a snap-fit ​​protrusion 4112. The snap-fit ​​protrusion 4112 engages with the slot 4122. The housing 41 is designed as two detachable parts, which facilitates the assembly and disassembly of the Hall rotor 42. The connection method of using the slot 4122 and the snap-fit ​​protrusion 4112 eliminates the need for unfastening operations, simplifies the assembly process, enables quick assembly and disassembly, and facilitates later maintenance. The first cylindrical portion 411 and the second cylindrical portion 412 are connected by a nesting method, making the housing 41 more compact, which helps to further reduce the size of the sensing component 4 and reduce the space occupied inside the pipeline.

[0068] For example, the inner wall of the first cylindrical portion 411 is provided with the above-mentioned snap-fit ​​protrusion 4112, and the outer wall of the second cylindrical portion 412 is provided with the above-mentioned snap-fit ​​groove 4122. The end of the first cylindrical portion 411 can be sleeved on the outside of the end of the second cylindrical portion 412, and is snapped and fixed by the snap-fit ​​protrusion 4112 and the snap-fit ​​groove 4122.

[0069] See Figure 4 and Figure 5 The first cylindrical part 411 has an end plate 4113 at the end away from the second cylindrical part 412. The end plate 4113 is provided with the above-mentioned multiple water inlet holes 4111. A first rotating seat 4114 is provided at the center of the end plate 4113. The first rotating seat 4114 is provided with a rotating hole 413.

[0070] See Figure 4 and Figure 6 The second cylindrical part 412 has an opening at one end away from the first cylindrical part 411. Multiple connecting ribs 4124 are arranged circumferentially at the opening. The ends of the multiple connecting ribs 4124 away from the inner wall of the second cylindrical part 412 are all connected to a second rotating seat 4123. A water outlet hole 4121 is formed between each two adjacent connecting ribs 4124. The second rotating seat 4123 is provided with a rotating hole 413.

[0071] Example 2

[0072] This embodiment provides a display device for a shower faucet, which differs from Embodiment 1 in that:

[0073] See Figure 7 The Hall rotor 42 includes a rotating shaft 421, a magnetic body 423, and guide vanes 424. The guide vanes 424 and the magnetic body 423 are spaced apart on the rotating shaft 421 along the water flow direction, and multiple magnetic bodies 423 are spaced apart circumferentially on the rotating shaft 421. Multiple guide vanes 424 are also spaced apart circumferentially on the rotating shaft 421, and each guide vane 424 is inclined relative to the rotating shaft 421. When water flows into the housing 41, the water flow impacts the guide vanes 424. When the water flow acts on the surface of the guide vanes 424, the pressure difference between the two sides of the guide vanes 424 forms a rotational driving force. The inclined guide vanes 424 generate a rotational tendency, which in turn drives the magnetic bodies 423 on the rotating shaft 421 to rotate, causing the Hall rotor 42 to generate a changing magnetic field.

[0074] In this embodiment, the guide vane 424 is similar to the fan blade. With the guide vane 424 provided, the water inlet hole 4111 and the water outlet hole 4121 on the housing 41 can both be designed as non-slanted holes. The rotation of the guide vane 424 is achieved by the water flow impacting the water flow, thereby realizing the rotation of the Hall rotor 42.

[0075] Of course, in some embodiments, the inlet hole 4111 and / or the outlet hole 4121 may be designed as inclined holes to further enhance the water flow driving effect.

[0076] Example 3

[0077] like Figure 1 As shown, this embodiment provides a shower faucet, including a mounting housing 10, a valve body assembly 20, and a display device for the shower faucet as described in any of the previous embodiments. The valve body assembly 20 is disposed within the mounting housing 10, and the display screen 1 of the display device is disposed within the mounting housing 10. The valve body assembly 20 includes a main pipe 201, and the sensing component 4 of the display device is disposed within the main pipe 201. After the shower faucet is installed on the wall, the mounting housing 10 can be flush with the wall, or the mounting housing 10 can be kept at a certain distance from the wall.

[0078] The shower faucet using this display device can automatically control the display screen 1 to light up or turn off based on the water flow in the main pipe 201, making it convenient for users to observe or operate the display screen 1 while using the shower faucet. Furthermore, the display device of this shower faucet eliminates the need for a separate hydroelectric generator, simplifying the structure and reducing manufacturing costs. The reduced number of parts also minimizes space requirements, facilitating the miniaturization of the shower faucet design.

[0079] See Figure 1The valve body assembly 20 also includes a plurality of control valves 202 disposed on the main pipeline 201. The control valves 202 are used to control the water outlet mode and / or the on / off state of the main pipeline 201. For example, five control valves 202 may be provided, one of which ( Figure 1 The control valve 202 in the lower right corner is used to control the ratio of cold water to hot water. The other four control four different water output modes, such as the overhead shower, hand shower, booster spray gun, and bottom faucet.

[0080] In other embodiments, the number of control valves 202 may also be three, six, etc., which can be increased or decreased according to actual needs, and are not limited to the number listed above.

[0081] In this embodiment, the display screen 1 is disposed on Figure 1 On the knob end of the control valve 202 in the lower right corner, users can directly adjust the temperature and view the current water temperature by rotating the knob, making operation more intuitive and convenient. Of course, in other embodiments, the display screen 1 can also be set in the mounting housing 10 or other locations, depending on actual needs, and is not limited to the locations listed in this embodiment.

[0082] See Figure 1 and Figure 2 The main pipeline 201 includes a detachably connected first pipe section 2011 and a second pipe section 2012. The first pipe section 2011 has a receiving groove 20111 within which the sensing component 4 is located. The second pipe section 2012 is inserted into the first pipe section 2011 and can axially confine the sensing component 4 within the receiving groove 20111. When installing the sensing component 4, the entire sensing component 4 is first inserted into the receiving groove 20111, and then one end of the second pipe section 2012 is inserted into the first pipe section 2011 to seal the receiving groove 20111. This prevents axial movement of the sensing component 4, ensures the relative position of the sensing component 4 and the Hall effect sensor 3, and improves the detection accuracy of the Hall effect sensor 3.

[0083] See Figure 2 The second pipe section 2012 is provided with a sealing element 203. After the second pipe section 2012 is inserted into the first pipe section 2011, the two are sealed together by the sealing element 203 to prevent water leakage. For example, the sealing element 203 is a sealing ring sleeved on the outside of the second pipe section 2012. Two sealing rings are provided to improve the sealing performance.

[0084] The shower faucet also includes a first water inlet connector 30 and a second water inlet connector 40. Both the first water inlet connector 30 and the second water inlet connector 40 are selectively connected to the main pipe 201. The first water inlet connector 30 can be connected to the hot water supply pipe to provide hot water, and the second water inlet connector 40 can be connected to the cold water supply pipe to provide cold water.
