Description

Technical Field

[0001] This application relates to the field of valve technology, specifically a household IoT smart valve. Background Technology

[0002] IoT smart valves are household valve devices that integrate IoT technology and intelligent control functions. They are mainly used in homes or small buildings for the management of water, gas, heating, etc. They feature intelligence, automation, and remote control, which can improve ease of use, safety, and management efficiency.

[0003] Chinese utility model patent CN222277512U discloses an intelligent valve for urban heating. It controls the gas flow during heating by controlling the synchronous rotation of three valve cores, thus avoiding unnecessary energy waste and effectively saving energy and reducing energy consumption and operating costs. However, when this intelligent valve is applied in a residential setting, its reliance on a single motor to drive the valve cores makes it overly dependent on the electric drive component. If the electric drive component malfunctions, such as a circuit fault or motor damage, the valve will be unable to open or close properly. When a fault occurs, maintenance personnel need to spend more time and effort troubleshooting. If the valve malfunction is not repaired in time, it will seriously affect residents' normal use and disrupt the normal operation of the entire system.

[0004] Therefore, this application provides a household IoT smart valve to solve the above problems. Utility Model Content

[0005] This application provides a household IoT smart valve, which aims to solve the problems mentioned in the background art, such as the fact that existing smart valves rely too much on electric drive because they only use a single motor to drive the valve core, and the valve cannot open and close normally when a fault occurs, thus affecting the operation of the system.

[0006] To achieve the above objectives, this application provides the following technical solution: a household IoT smart valve, comprising a microcontroller, a valve body, two channels respectively disposed on both sides of the valve body, a valve core assembly disposed within the valve body, and an electric mechanism disposed on the valve body for driving the valve core assembly to rotate and thus opening or closing the two channels, wherein the electric mechanism is connected to the output terminal of the microcontroller;

[0007] The IoT smart valve also includes an emergency mechanism installed on the valve body for manually driving the valve core assembly to rotate when the electric mechanism malfunctions.

[0008] The emergency mechanism includes a gear mounted on the valve core assembly, a rack mounted on one side of the gear, and a linear assembly mounted on the valve core assembly for sliding the rack close to and engaging the gear. When the electric mechanism malfunctions, the linear assembly can be manually operated to slide the rack close to and engage the gear, transmitting the rack's sliding power to the gear. This causes the gear to rotate the valve core assembly, thus manually opening or closing the passage. This dual-drive mode improves the reliability of the valve, ensuring normal opening or closing even when the electric mechanism fails, preventing the entire system from being affected by the valve's inoperability.

[0009] Preferably, in order to enable or disable the two channels, the valve core assembly includes a valve disc rotatably connected to the valve body and located between the two channels, a connecting box fixedly installed on the outside of the valve body at a position corresponding to the valve disc above the valve disc, and a valve stem that passes through the connecting box and the valve body in sequence and is fixedly connected to the valve disc. The valve stem is rotatably connected to the valve body and the connecting box. When the valve stem rotates, it will drive the valve disc to rotate, thereby changing the relative position of the valve disc with the two channels and enabling or disabling the two channels.

[0010] Preferably, to drive the valve stem, the electric mechanism includes a mounting box fixedly mounted on the connecting box, a rotating shaft rotatably connected inside the connecting box and fixedly connected to the valve stem, and a motor fixedly mounted inside the mounting box and connected to the output terminal of a microcontroller for driving the rotating shaft to rotate. An electromagnetic clutch is provided on the rotating shaft, and the rotating shaft is fixedly connected to the output shaft of the motor via the electromagnetic clutch. When a control signal is sent by the microcontroller to rotate the motor, the motor, through the electromagnetic clutch, drives the rotating shaft to rotate, thereby driving the valve stem and valve disc to rotate, thus enabling or disabling the two channels. This achieves automated control of the valve, improving operational convenience and efficiency.

[0011] Preferably, in order to achieve the sliding of the rack and the rotation of the gear, the linear component includes a lead screw passing through the connecting box and rotatably connected inside the connecting box, and a handwheel disposed outside the connecting box and fixedly connected to the lead screw. The lead screw is screwed to the rack, the rack is slidably connected inside the mounting box, and the gear is fixedly sleeved on the valve stem. Through the screwed transmission between the lead screw and the rack, the rotation of the handwheel can be converted into the linear motion of the rack when manually operated. Thus, through the meshing of the rack and the gear, the gear and the valve stem can be driven to rotate, thereby realizing the manual control of the opening or closing of the two channels.

[0012] Preferably, to prevent accidental activation of the handwheel during daily use, the emergency mechanism further includes an anti-touch component disposed on the handwheel and connected to the connection box for locking the handwheel to prevent accidental activation. The anti-touch component is designed to lock the handwheel when it is not in use, preventing accidental activation during daily use and thus affecting the normal operation of the entire system. This ensures that the anti-touch component is only released when the emergency mechanism needs to be manually operated, guaranteeing the stability and safety of the valve in non-manual operation mode.

[0013] Preferably, to achieve the locking of the handwheel to prevent accidental activation, the anti-activation component includes a locking screw screwed to one side of the handwheel for abutting against the outside of the connecting box, and a knob fixedly connected to the end of the locking screw away from the connecting box. This design allows the user to lock and unlock the handwheel simply by rotating the knob, thereby preventing the handwheel from being accidentally turned during daily use, avoiding changes in the valve status due to accidental handwheel activation, and ensuring the stable operation of the entire system.

[0014] This household IoT smart valve allows for manual operation of a linear component that slides a rack close to and engages with a gear. This transmits the rack's sliding power to the gear, causing the gear to rotate the valve core assembly. This allows for manual opening or closing of the channel. This dual-drive mode improves the valve's reliability, ensuring normal opening or closing even in the event of a malfunction in the electric mechanism, thus preventing the entire system from being affected by the valve's inability to operate.

[0015] This household IoT smart valve features an anti-touch component design. The anti-touch component locks the handwheel only when manual operation of the emergency mechanism is required, ensuring the stability and safety of the valve in non-manual operation mode. Attached Figure Description

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] Example 1

[0028] This embodiment provides a household IoT smart valve, such as... Figures 1-3 As shown, the IoT smart valve includes a microcontroller, a valve body 1, two channels 2 respectively disposed on both sides of the valve body 1, a valve core assembly 3 disposed inside the valve body 1, and an electric mechanism 4 disposed on the valve body 1 for driving the valve core assembly 3 to rotate and open or close the two channels 2. The electric mechanism 4 is connected to the output terminal of the microcontroller. The IoT smart valve also includes an emergency mechanism 5 disposed on the valve body 1 for manually driving the valve core assembly 3 to rotate when the electric mechanism 4 malfunctions. The emergency mechanism 5 includes a gear 51 disposed on the valve core assembly 3, a rack 52 disposed on one side of the gear 51, and a linear component 53 disposed on the valve core assembly 3 for sliding the rack 52 close to the gear 51 and engaging it.

[0029] In operation, the microcontroller sends control signals according to a preset program or external instructions. Since the electric mechanism 4 is connected to the microcontroller's output, it starts working upon receiving the signal. It drives the valve core assembly 3 inside the valve body 1 to rotate. The rotation of the valve core assembly 3 changes the relative position of the two channels 2 on both sides of the valve body 1, thereby opening or closing the two channels 2 to complete the automated control function of the valve. However, when the electric mechanism 4 malfunctions, such as a fault or circuit interruption, preventing it from properly driving the valve core assembly 3, the emergency mechanism 5 comes into play. At this time, the operator manually operates the linear actuator... The component 53 is moved, causing the rack 52 to slide. During the sliding process, the rack 52 gradually approaches the gear 51 set on the valve core assembly 3 until it meshes with the gear 51. Once the rack 52 meshes with the gear 51, as the rack 52 continues to move, the moving power of the rack 52 can be transmitted to the gear 51, causing the gear 51 to rotate. Since the gear 51 is connected to the valve core assembly 3, the rotation of the gear 51 will drive the valve core assembly 3 to rotate, thereby manually opening or closing the two channels 2, ensuring that the valve can still work normally when the electric mechanism 4 fails, and ensuring the stable operation of the entire system.

[0030] Specifically, the valve core assembly 3 includes a valve disc 31 rotatably connected inside the valve body 1 and located between two channels 2, a connecting box 33 fixedly installed on the outside of the valve body 1 at a position above the valve disc 31, and a valve stem 32 that passes through the connecting box 33 and the valve body 1 in sequence and is fixedly connected to the valve disc 31. The valve stem 32 is rotatably connected inside the valve body 1 and the connecting box 33.

[0031] When it is necessary to control the opening or closing of the two channels 2, the valve stem 32 is driven by the electric mechanism 4 or the emergency mechanism 5. When the valve stem 32 rotates, since the valve stem 32 is fixedly connected to the valve disc 31, the rotation of the valve stem 32 will drive the valve disc 31 to rotate synchronously. As the valve disc 31 rotates, it will change its relative position with the two channels 2. When the valve disc 31 rotates to a specific position, the two channels 2 can be connected to each other to achieve conduction. When the valve disc 31 rotates to other positions, it can block the connection between the two channels 2 to achieve closing, thereby realizing the opening or closing of the two channels 2.

[0032] Furthermore, the electric mechanism 4 includes a mounting box 41 fixedly mounted on the connecting box 33, a rotating shaft 42 rotatably connected in the connecting box 33 and fixedly connected to the valve stem 32, and a motor 43 fixedly mounted in the mounting box 41 and connected to the output terminal of the microcontroller for driving the rotating shaft 42 to rotate. An electromagnetic clutch 44 is provided on the rotating shaft 42, and the rotating shaft 42 is fixedly connected to the output shaft of the motor 43 through the electromagnetic clutch 44.

[0033] When the microcontroller issues a control command to start the motor 43, its output shaft will generate rotational power. Since the rotating shaft 42 is rotatably connected in the connecting box 33 and fixedly connected to the valve stem 32, and the rotating shaft 42 is fixedly connected to the output shaft of the motor 43 through the electromagnetic clutch 44, the electromagnetic clutch 44 is in the engaged state under normal working conditions. Therefore, by connecting the output shaft of the motor 43 and the rotating shaft 42 through the electromagnetic clutch 44, the power of the output shaft of the motor 43 can be transmitted to the rotating shaft 42, causing the rotating shaft 42 to rotate. In turn, the rotating shaft 42 will drive the valve stem 32 to rotate, ultimately realizing the rotation of the valve disc 31, so as to complete the automated control of opening or closing the two channels 2. When the electric mechanism 4 malfunctions, such as a fault or circuit interruption, and the emergency mechanism 5 needs to be manually operated, the electromagnetic clutch 44 will disengage, cutting off the power transmission between the output shaft of the motor 43 and the rotating shaft 42, avoiding mutual interference between manual operation and electric operation.

[0034] Furthermore, the linear assembly 53 includes a lead screw 531 that passes through the connecting box 33 and is rotatably connected inside the connecting box 33, and a handwheel 532 that is disposed outside the connecting box 33 and fixedly connected to the lead screw 531. The lead screw 531 is screwed to the rack 52, the rack 52 is slidably connected inside the mounting box 41, and the gear 51 is fixedly sleeved on the valve stem 32.

[0035] When the electric mechanism 4 malfunctions, such as a fault or circuit interruption, and the emergency mechanism 5 needs to be operated manually, the electromagnetic clutch 44 will disengage, cutting off the power transmission between the output shaft of the motor 43 and the rotating shaft 42 to avoid interference between manual and electric operation. At this time, the operator manually turns the handwheel 532. Since the handwheel 532 is located outside the connecting box 33 and is fixedly connected to the lead screw 531 that passes through and rotatably connects to the connecting box 33, the rotation of the handwheel 532 will drive the lead screw 531 to rotate synchronously. Since the lead screw 531 is screwed to the rack 52 which is slidably connected in the mounting box 41, when the lead screw 531 rotates, through the screw connection, the lead screw 531 will convert its rotational motion into the linear motion of the rack 52, causing the rack 52 to slide along the inside of the mounting box 41. As the rack 52 moves, it will gradually approach the gear 51 fixedly sleeved on the valve stem 32 until the rack 52 meshes with the gear 51. Then, the handwheel 532 is operated to continue moving the rack 52. Through the meshing of the rack 52 and the gear 51, the power of the rack 52's movement will be transmitted to the gear 51, causing the gear 51 to rotate. In turn, the gear 51 drives the valve stem 32 to rotate, ultimately realizing the manual control of the opening or closing of the two channels 2.

[0036] Example 2

[0037] Unlike Example 1, as Figure 3 and Figure 4As shown, the emergency mechanism 5 also includes an anti-touch component 54 installed on the handwheel 532 and connected to the connection box 33 for locking the handwheel 532 to prevent accidental contact. The anti-touch component 54 is designed to lock the handwheel 532 when it is not in use, so as to prevent accidental contact of the handwheel 532 during daily use and thus affecting the normal operation of the entire system. The anti-touch component 54 is only released when the emergency mechanism 5 needs to be manually operated, thus ensuring the stability and safety of the valve in the non-manual operation state.

[0038] Furthermore, the anti-touch component 54 includes a locking screw 541 screwed to one side of the handwheel 532 for abutting against the outside of the connection box 33, and a knob 542 fixedly connected to the end of the locking screw 541 away from the connection box 33.

[0039] When handwheel 532 is not in use and needs to be locked, the operator rotates knob 542, which drives locking screw 541 to rotate. Since locking screw 541 is screwed to handwheel 532, during rotation, locking screw 541 will move towards connecting box 33 until the end of locking screw 541 is tightly pressed against the outside of connecting box 33. At this time, handwheel 532 is locked and cannot be rotated. When it is necessary to manually operate handwheel 532 to drive emergency mechanism 5, the operator rotates knob 542 in the opposite direction, which drives locking screw 541 to rotate in the opposite direction, gradually moving it away from connecting box 33, releasing the tightness between locking screw 541 and connecting box 33, thereby releasing the lock on handwheel 532, and handwheel 532 can then be operated.

[0040] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
