Description

Technical Field

[0001] The present invention relates to the technical field of bathroom water channels, and in particular to an electronic induction water channel mechanism. Background Art

[0002] In bathroom water systems, electronic sensing water system mechanisms are often used to display information such as water temperature so that users can observe, adjust and manage it.

[0003] Existing electronic sensing water circuit mechanisms typically use purely electronic control to control on / off lighting and display screens. These systems include a purely electronic display device and temperature sensor. The display device is integrated into the water circuit housing, and the temperature sensor is installed within the water circuit within the housing. The temperature sensor transmits the detected temperature signal to the display device's controller, which then displays the current water temperature on the screen.

[0004] A drawback of existing electronic sensing water circuit mechanisms is that the screen remains permanently on unless the user turns off the display. Regardless of whether the user is using the water or not, the screen constantly displays the current water temperature, consuming significant electricity. Existing electronic sensing water circuit mechanisms do not automatically turn on and off when the water circuit mechanism is turned on or off. At night, the permanently on screen emits red or blue light, requiring users with light sensitivity to specifically turn off the display, resulting in a poor user experience. Summary of the Invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an electronic sensing waterway mechanism that uses a reed switch sensor and a sliding element with a magnet to achieve automatic sensing. When the waterway is closed, the sliding element drives the magnet to the initial position, the reed switch sensor is in the first trigger state, and sends a first signal to the control panel, and the display screen goes out; when the waterway is opened, the sliding element drives the magnet to slide to the downstream side of the initial position, the reed switch sensor switches from the first trigger state to the second trigger state, and sends a second signal to the control panel, and the display screen starts to display the water temperature. The display screen can automatically turn on and off as the waterway is turned on and off, saving electricity. The user no longer needs to specifically turn off the display screen, which improves the user experience.

[0044] The following further describes specific embodiments of the present invention with reference to the accompanying drawings. Like components are denoted by like reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inward" and "outward" refer to directions toward or away from the geometric center of a particular component, respectively.

[0045] like Figure 1-5 and Figure 9-10 As shown, an electronic sensing waterway mechanism provided by one embodiment of the present invention includes a mechanism body 1 having a waterway 11 , a display module 2 integrated on the mechanism body 1 , and a temperature sensor 3 for monitoring the water temperature in the waterway 11 .

[0046] The temperature sensor 3 is connected to the control board 21 of the display module 2 via a signal connection.

[0047] A reed switch sensor 4 is installed on one side of the water channel 11 in the main body 1, and the reed switch sensor 4 is connected to the control board 21. The reed switch sensor 4 has a first trigger state and a second trigger state.

[0048] A sliding element 5 that can be pushed by water flow is installed in the water channel 11 , and an elastic element 6 for driving the sliding element 5 to reset is also installed in the water channel 11 .

[0049] A magnet 7 for triggering the reed switch sensor 4 is mounted on the sliding element 5 .

[0050] When the water channel 11 is in a water-stop state, the sliding element 5 is in an initial position, the reed switch sensor 4 is in a first triggering state, and the display screen 22 of the display module 2 is in an off state.

[0051] When the water channel 11 is in a water flow state, the sliding element 5 is at the downstream side of the initial position, the reed switch sensor 4 is in the second triggering state, and the display screen 22 is in a display state.

[0052] The electronic sensing waterway mechanism provided by the present invention is used in bathroom waterways and can display information such as temperature signals. The terms "upstream" or "upstream side" and "downstream" or "downstream side" referred to in the present invention are defined based on the direction of water flow. For example, the side of a component facing the incoming water flow is the upstream side, and the side facing the outgoing water flow is the downstream side.

[0053] The electronic induction waterway mechanism includes a mechanism body 1, a display module 2, a temperature sensor 3, a reed switch sensor 4, a sliding element 5, an elastic element 6 and a magnet 7.

[0054] The main body 1 of the mechanism has a water path 11, which can be a water pipe, a pipeline, or a channel. The main body 1 is equipped with a water inlet and a water outlet connected to the outside. The water inlet is used to connect to a water supply pipe, such as a hot and cold water pipe, and the water outlet is used to connect to the water pipes of bathroom products, such as showers and faucets. The main body 1 can also be equipped with a button switch 12 for controlling the opening and closing of the water path 11. The main body 1 can also be equipped with a water temperature regulating valve 13, which connects hot and cold water to achieve a temperature control function. The main body 1 is a conventional structure in the prior art and will not be described in detail here.

[0055] The display module 2 is an electronic display mechanism, which includes a control board 21 and a display screen 22. The control board 21 is an existing printed circuit board with a control function. The display screen 22 is an existing liquid crystal display screen.

[0056] The display module 2 is mounted in the main body 1 via fasteners. In an alternative mounting method, the display module 2 is mounted in the main body 1 via a snap-fit structure 9. The housing of the display module 2 has a boss 23, and the snap-fit structure 9 has a hook 91. The snap-fit structure 9 is mounted in the mounting cavity of the main body 1 via fasteners. The hook 91 engages the boss 23 to secure the display module 2. The display screen 22 is exposed from one side of the main body 1.

[0057] Temperature sensor 3 monitors the real-time water temperature in waterway 11. The probe end of temperature sensor 3 extends into waterway 11. The main body of temperature sensor 3 is secured to the main body 1 by a nut 15. Temperature sensor 3 is connected to control board 21 via wires for signal transmission. Temperature sensor 3 transmits the detected temperature signal to control board 21, which then displays the temperature on display screen 22.

[0058] The reed switch sensor 4, also known as a magnetic reed switch, is a switch that can be turned on or triggered by a magnetic field. The reed switch sensor 4 is connected to the control board 21 via a wire 41 to achieve signal transmission. The reed switch sensor 4 has a first trigger state and a second trigger state. When the reed switch sensor 4 is in the first trigger state, the reed switch sensor 4 sends a first signal to the control board 21, which causes the display screen 22 to automatically turn off, for example, by automatically disconnecting the circuit of the display screen 22. When the reed switch sensor 4 is in the second trigger state, the reed switch sensor 4 sends a second signal to the control board 21, which causes the display screen 22 to automatically turn on, for example, by automatically closing the circuit of the display screen 22.

[0059] The reed switch sensor 4 has two overlapping reeds with a gap between them. The two reeds can be brought into contact by a magnetic field. When the two reeds are not in contact, the reed switch sensor 4 is in a first trigger state. When the two reeds are in contact, the reed switch sensor 4 is in a second trigger state. When the two reeds are in contact, the reed switch sensor 4 is in the first trigger state. When the two reeds are not in contact, the reed switch sensor 4 is in the second trigger state. The first and second trigger states can be set as needed.

[0060] The reed switch sensor 4 is installed in the mechanism body 1 and is located on one side of the water channel 11 .

[0061] Sliding element 5 is slidably mounted within waterway 11, preferably downstream of water temperature control valve 13. An elastic element 6 is coupled to sliding element 5 and is used to actuate sliding element 5 back to its initial position. When push button switch 12 opens waterway 11, sliding element 5 is forced by the water flow to move from its initial position and slide downstream within waterway 11. When push button switch 12 closes waterway 11, elastic element 6 actuates sliding element 5 back to its initial position.

[0062] The magnet 7 is mounted on the sliding element 5 and is used to provide a magnetic field to the reed switch sensor 4 so as to bring the two reeds inside the reed switch sensor into contact.

[0063] When the sliding element 5 drives the magnet 7 to be in the initial position, the reed switch sensor 4 is in the first triggering state. When the sliding element 5 drives the magnet 7 to slide to the downstream side of the initial position, the reed switch sensor 4 is in the second triggering state.

[0064] For example, the reed switch sensor 4 is configured such that when the two reeds are not in contact, the reed switch sensor 4 is in a first trigger state; when the two reeds are in contact, the reed switch sensor 4 is in a second trigger state. The reed switch sensor 4 or its reed is arranged downstream of the initial position of the magnet 7. When the sliding element 5 drives the magnet 7 to the initial position, the magnet 7 and the reed switch sensor 4 or its reed are offset from each other, and the magnetic field of the magnet 7 does not act on the reeds, resulting in the two reeds not in contact. When the sliding element 5 drives the magnet 7 to slide to the downstream side of the initial position, the magnet 7 approaches the reed switch sensor 4 or its reed, and the magnetic field of the magnet 7 acts on the reeds, resulting in the two reeds in contact.

[0065] For example, the reed switch sensor 4 is configured such that when the two reeds are in contact, the sensor is in a first trigger state, and when the two reeds are not in contact, the sensor is in a second trigger state. Therefore, the reed switch sensor 4 or its reed is positioned at the initial position of the magnet 7, or the magnet 7 in its initial position is close to the sensor 4 or its reed. The magnetic field of the magnet 7 acts on the reeds, causing the two reeds to contact. When the sliding element 5 drives the magnet 7 to slide downstream of the initial position, the magnetic field of the magnet 7 no longer acts on the reeds, causing the two reeds to not contact.

[0066] When the user operates the button switch 12 to close the water channel 11 and the water channel 11 is in a water-stop state, under the action of the elastic element 6, the sliding element 5 drives the magnet 7 to the initial position, the reed switch sensor 4 is in the first trigger state, and the display screen 22 is in the off state.

[0067] When the user operates the button switch 12 to open the water channel 11, and the water channel 11 is in a water flow state, at this time, under the action of the water flow, the sliding element 5 drives the magnet 7 to leave the initial position and slide downstream, the reed switch sensor 4 is in the second trigger state, and the display screen 22 is in the display state.

[0068] Each of the above electrical components may have its own battery or be connected to an external circuit through a converter.

[0069] In summary, the electronic sensing water channel mechanism provided by the present invention has a display screen 22 that can be automatically turned on and off as the water channel 11 is turned on and off, saving electricity. The user no longer needs to specifically turn off the display screen 22, thereby improving the user experience.

[0070] In this embodiment, when the sliding element 5 is in the initial position, the magnet 7 mounted on the sliding element 5 is upstream of the contact 41, and the magnetic field of the magnet 7 does not act on the contact 41, thereby ensuring that the reed switch sensor 4 is in an untriggered state.

[0071] When the water channel 11 is opened to allow water to flow, the sliding element 5 drives the magnet 7 to slide downstream, and the magnet 7 moves between the two ends of the contact 41. The magnetic field of the magnet 7 acts on the contact 41 to ensure that the reed switch sensor 4 is in a triggered state.

[0072] In one embodiment, Figure 4 As shown, the magnet 7 is embedded in the sliding element 5 to prevent it from being washed away by water and affecting its service life.

[0073] As needed, a sleeve or a cavity may be configured on the sliding element 5 to assemble the magnet 7 in the sleeve or the cavity.

[0074] In one embodiment, Figure 4 As shown, the magnet 7 is located on the side of the sliding element 5 close to the reed switch sensor 4, shortening the distance between the magnet 7 and the reed switch sensor 4. The sliding element 5 drives the magnet 7 to slide downstream. When the magnet 7 moves between the two ends of the contact 41, the distance between the magnet 7 and the contact 41 is shortened, and the magnetic field has a better effect on the two contacts 41.

[0075] In one embodiment, Figure 4 and Figure 6-8 As shown, the sliding element 5 includes a sliding end cover 51 and a guide column 52 connected to the sliding end cover 51 .

[0076] A mounting portion 53 is provided on the side of the sliding end cover 51 facing the reed switch sensor 4 , and the magnet 7 is embedded in the mounting portion 53 .

[0077] A guide bracket 8 is provided in the water channel 11 downstream of the sliding end cover 51 , and the guide post 52 is slidably connected to the guide bracket 8 .

[0078] The elastic element 6 is connected between the guide bracket 8 and the sliding end cover 51 and / or the guide column 52 .

The sliding end cover 51 is slidably mounted in the waterway 11, and the guide post 52 is connected to the downstream side of the sliding end cover 51. Preferably, the sliding end cover 51 is a circular end cover, and the guide post 52 is coaxially arranged with the sliding end cover 51.

[0080] A guide bracket 8 is installed in the waterway 11, which is located on the downstream side of the sliding end cover 51. A guide post 52 is slidably connected to the guide bracket 8. The guide bracket is provided with a guide hole / guide groove, and the guide post 52 passes through the guide hole / guide groove.

[0081] The elastic element 6 can be selectively connected between the guide bracket 8 and the sliding end cover 51 , or can be selectively connected between the guide bracket 8 and the guide column 52 . The elastic element 6 can also be connected to the sliding end cover 51 and the guide column 52 at the same time.

[0082] A mounting portion 53 is provided on the sliding end cap 51, located on the side facing the reed switch sensor 4. The magnet 7 is embedded in the mounting portion 53. The mounting portion 53 can be a sleeve with a sealing cover, or a mounting cavity can be defined in the mounting portion 53, with a sealing cover provided over the opening of the cavity.

[0083] In one embodiment, Figure 4 and Figure 6-8 As shown, the sliding end cover 51 is tapered, and the radius of the sliding end cover 51 gradually increases in the direction from the sliding end cover 51 to the guide bracket 8.

[0084] In this embodiment, the sliding end cover 51 is umbrella-shaped, and the radius of the sliding end cover 51 gradually increases in the direction from the upstream side to the downstream side. On the one hand, it allows the water in the waterway 11 to flow along the conical surface of the sliding end cover 51, reducing the obstruction to the water flow. On the other hand, the action of the water flow can also be used to drive the sliding end cover 51 to slide toward the downstream side.

[0085] In one embodiment, Figure 6-7 As shown, a reinforcing rib 54 is provided on the outer surface of the sliding end cover 51. At least one reinforcing rib 54 is connected to the mounting portion 53.

[0086] In this embodiment, a plurality of reinforcing ribs 54 are integrally provided on the outer surface of the sliding end cover 51 , wherein one of the reinforcing ribs 54 is connected to the mounting portion 53 to improve the stability of the mounting portion 53 .

[0087] In one embodiment, Figure 4 and Figure 8 As shown, a guide sleeve 85 is provided in the middle of the guide bracket 8 , and the guide column 52 passes through the guide sleeve 85 , so that the guide sleeve 85 provides guidance for the linear movement of the guide column 52 .

[0088] In one embodiment, Figure 4 and Figure 8 As shown, the elastic element 6 is a spring 61, which is sleeved on the guide column 52. One end of the spring 61 is connected to the sliding end cover 51, and the other end of the spring 61 is sleeved on the guide sleeve 85, which is convenient for installing and fixing the spring 61 and also conducive to guiding the deformation of the spring 61.

[0089] In one embodiment, Figure 4 and Figure 8As shown, the guide bracket 8 comprises an annular frame 81, a tapered sleeve 82, partitions 83, and a guide sleeve 85. The tapered sleeve 82 is located within the annular frame 81, and the two are connected by multiple partitions 83. Water holes 84 are formed between adjacent partitions 83. The annular frame 81 is fixedly mounted on the stop step of the waterway 11. The guide sleeve 85 is located within the tapered sleeve 82, and the downstream sides of the two are connected by a connecting plate. The radius of the tapered sleeve 82 gradually increases from the downstream side to the upstream side. The spring 61 is mounted on the guide post 52. One end of the spring 61 is connected to the sliding end cover 51, and the other end of the spring 61 is mounted on the guide sleeve 85 and located between the guide sleeve 85 and the tapered sleeve 82. The tapered sleeve 82 has a large opening facing the sliding end cover 51, making it easy to insert the other end of the spring 61 into the annular cavity between the guide sleeve 85 and the tapered sleeve 82.

[0090] In one embodiment, Figure 2 As shown, the mechanism body 1 has a battery box 14, and batteries are installed in the battery box 14. The display module 2, the temperature sensor 3 and the reed switch sensor 4 are electrically connected to the batteries respectively.

[0091] In this embodiment, a battery box 14 is provided in the main body 1 for installing batteries. The display module 2, the temperature sensor 3 and the reed switch sensor 4 are connected to the battery via wires, and the battery provides power to the various electrical components.

[0092] In one embodiment, Figure 10 As shown, a light-transmitting shield 25 is installed on the outer side of the display screen 22 to protect the display screen 22.

[0093] The display module 2 has a side with a display screen 22 and is provided with a flange 24. A light-transmitting shield 25 is connected to the flange 24. The light-transmitting shield 25 can be a glass cover.

[0094] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0095] The above are only the principles and preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several other variations can be made based on the principles of the present invention, which should also be considered as the scope of protection of the present invention.
