Description

Technical Field

[0001] The present invention relates to a toilet lid control device. Background Art

[0002] A toilet is provided with a toilet lid and a seat ring. For traditional toilets, the opening and closing of the toilet lid and the seat ring are both manually operated. For the elderly and children with inconvenient mobility, it is relatively difficult to use. Although existing intelligent toilets have the function of automatically controlling the toilet lid and the seat ring, due to the limitations of the existing layout of the bathroom, it is difficult to install an intelligent toilet, and even the upper and lower water pipelines need to be re-laid, which is more difficult for construction in old communities. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a toilet lid control device, which is a device installed on an existing traditional toilet, and can perform the functions of automatically flipping the toilet lid and the seat ring, making it convenient to use.

[0004] To solve the above technical problem, the present invention provides a toilet lid control device, including a main body installed on the toilet water tank, a torsion spring reset device and a seat ring synchronization device installed on the toilet lid, and an external foot switch. The main body of the host is provided with two independently driven wire winding boxes, a main power supply, a main controller, a human body sensor, and a signal transceiver. The two wire winding boxes are symmetrically arranged in the middle area of the main body of the host. Each wire winding box is provided with a wire, and the wire outlet directions of the two wire winding boxes are both forward. The two wire winding boxes, the human body sensor, and the signal transceiver are all connected to the main power supply through the main controller. The foot switch is internally provided with a signal transmitter and a corresponding power supply.

[0005] For the sake of simplicity in explaining the problem, hereinafter, a toilet lid control device described in the present invention is simply referred to as this device.

[0006] The usage method of this device: Fix the main body of the host of this device on the toilet water tank. The ends of the two wires away from the corresponding wire winding boxes are connected to the front part of the upper side of the toilet lid. The torsion spring reset device is arranged at the rear part of the upper side of the toilet lid. The seat ring synchronization device is installed at a position on the toilet lid corresponding to the seat ring. The foot switch is arranged on the ground near the toilet.

[0007] When in use, when the human body sensor detects someone approaching, the main controller controls the two wire winding boxes to wind the wires simultaneously. Under the action of the pulled wires, the toilet lid is lifted upward. At this time, the torsion spring reset device is torsionally stressed to form elastic potential energy for resetting the toilet lid. When the person who was originally within the monitoring range of the human body sensor leaves, the main controller controls the two wire winding boxes to unwind the wires simultaneously. The elastic potential energy in the torsion spring reset device is converted into kinetic energy to make the toilet lid reset and close. If it is necessary to lift the seat ring, by operating the foot kick switch, the foot kick switch is equivalent to an external remote control. The foot kick switch sends a synchronization signal to the main body of the host through a signal transmitter. Since the seat ring synchronization device can control the coordinated movement of the seat ring and the toilet lid, when the main controller in the main body of the host controls the wire winding box to wind the wires, it will send the synchronization signal to the seat ring synchronization device through the signal transceiver, so that the seat ring is lifted while the toilet lid is opened. Similarly, the seat ring can be synchronously closed when the toilet lid is closed. It is also possible to directly control only the opening of the toilet lid or the synchronous lifting of the seat ring when the toilet lid is opened and the closing of the toilet lid through the foot kick switch without the participation of the human body sensor.

[0008] Advantages of this device: This device is based on the existing traditional toilet and is installed on the existing toilet without changing the original position of the toilet, which is convenient for installation. After installing this device, the toilet lid can be automatically opened when a person comes and automatically closed when a person leaves, making it more convenient to use.

[0009] To achieve better use effects of this device, its preferred solutions are as follows:

[0010] Preferably, the seat ring synchronization device includes a horizontally arranged base. An extension chamber is provided on the lower side of the base. A vertically arranged rotating shaft is provided in the extension chamber. A gear is provided at the lower end of the rotating shaft. A rack with a front-back running length direction and meshing with the gear is provided beside the gear in the extension chamber. A locking tongue extending forward and exceeding the extension chamber is provided at the front end of the rack. The upper end of the rotating shaft extends upward through the extension chamber and through the base. Two vertically spaced limiting blocks are provided in the area corresponding to the upper side of the base at the position of the rotating shaft. A guiding component is provided at the position corresponding to the rear of the rotating shaft on the upper side of the base. The guiding component includes a frame. Two wire guiding wheel groups arranged at intervals front and back are provided on the frame. The axial directions of the two wire guiding wheel groups are both left-right. Each wire guiding wheel group is provided with two coaxially arranged wire guiding wheels. The horizontal tangent height of the lower wire guiding wheel group at the front side is between the heights of the two limiting blocks.

[0011] During installation, place the base under the toilet lid near the inner hole edge of the seat ring, such that when the toilet lid is closed, the position of the locking tongue is lower than the lower side of the seat ring. Drill a hole in the toilet lid so that the upper end of the rotating shaft and the upper part of the guiding component can pass through the toilet lid from bottom to top and be located above the toilet lid. The wire wheels on the same side of the two wire wheel groups in the left-right direction correspond to the pull wires led out from the corresponding wire spool. The pull wire of each wire spool first clips into the upper side of the wire wheel group at the rear, then extends downward, and horizontally protrudes forward from the lower side of the wire wheel group at the front. The ends of the two pull wires far from the corresponding wire spools are connected to form a U-shaped socket joint and are sleeved between the two limiting blocks of the rotating shaft.

[0012] During use, when the signal transceiver receives the synchronization signal sent by the signal transmitter, one of the two wire spools winds the wire and the other unwinds the wire. At this time, the U-shaped socket joint sleeved between the two limiting blocks of the rotating shaft will drive the rotating shaft to rotate. The gear on the lower side of the rotating shaft drives the rack to move forward, so that the locking tongue extends forward to the lower side of the seat ring. At this time, when the toilet lid is opened, the seat ring will also be synchronously lifted under the drive of the locking tongue. If only the toilet lid is opened, control the locking tongue to maintain the initial contracted state. At this time, when the toilet lid is opened, the seat ring will not be synchronously lifted. The same principle applies when closing the toilet lid. After the signal transceiver of the main body receives the synchronization signal from the signal transmitter on the foot switch, first control the locking tongue to extend forward to latch the seat ring, and then when the toilet lid is closed, the seat ring will also synchronously drop. If only the seat ring needs to be dropped without closing the toilet lid, first control the seat ring and the toilet lid to close synchronously, and then separately open the toilet lid.

[0013] Preferably, the seat ring synchronization device includes a horizontally arranged upper base and a lower base. The upper base and the lower base are arranged at an interval up and down. The upper base is provided with a first channel vertically penetrating the upper base. A vertically arranged first rotating shaft is provided in the first channel. The lower end of the first rotating shaft is flush with the lower end of the upper base and is provided with a first magnetic coupling. The upper end of the first rotating shaft extends beyond the upper base. Two limiting blocks arranged at an interval up and down are provided in the area corresponding to the upper side of the upper base at the position of the first rotating shaft. A second channel vertically penetrating the lower base is provided at the position of the lower base corresponding to the first channel of the upper base. A vertically arranged second rotating shaft is provided in the second channel. The upper end of the second rotating shaft is flush with the lower base and is provided with a second magnetic coupling matching the first magnetic coupling. An extension chamber is provided on the lower side of the lower base. The lower end of the second rotating shaft penetrates into the extension chamber and is provided with a gear. A rack with a front-back direction length and meshing with the gear is provided beside the gear in the extension chamber. The front end of the rack is provided with a locking tongue extending forward and beyond the extension chamber. A guiding component is provided at the position corresponding to the rear of the first rotating shaft on the upper side of the upper base. The guiding component includes a frame. Two wire wheel groups arranged at an interval front and back are provided on the frame. The axis directions of the two wire wheel groups are both left-right. Each wire wheel group is provided with two coaxially arranged wire wheels. The horizontal tangent height of the lower side of the wire wheel group at the front is between the heights of the two limiting blocks.

[0014] During installation, place the lower base at the position on the lower side of the toilet lid near the inner hole edge of the seat ring, so that when the toilet lid is closed, the position of the locking tongue is lower than the lower side of the seat ring. Place the upper base on the upper side of the toilet lid, and make the first magnetic coupling and the second magnetic coupling face each other. The wire wheels on the same side of the two wire wheel groups in the left-right direction correspond to the pull wires led out from the corresponding wire spool. The pull wire of each wire spool first clips into the upper side of the wire wheel group at the rear, then extends downward, and horizontally protrudes forward from the lower side of the wire wheel group at the front. The ends of the two pull wires away from the corresponding wire spools are connected to form a U-shaped socket joint and are sleeved between the two limit blocks of the rotating shaft.

[0015] During use, when the signal transceiver receives the synchronization signal sent by the signal transmitter, one of the two wire spools winds the wire and the other unwinds the wire. At this time, the U-shaped socket joint sleeved between the two limit blocks of the first rotating shaft will drive the first rotating shaft to rotate. Under the action of the first magnetic coupling and the second magnetic coupling, the first rotating shaft transmits the torque to the second rotating shaft. The gear on the lower side of the second rotating shaft drives the rack to move forward, so that the locking tongue extends forward to the lower side of the seat ring. At this time, when the toilet lid is opened, the seat ring will also be synchronously lifted under the drive of the locking tongue. If only the toilet lid is opened, the locking tongue is controlled to maintain the initial contracted state. At this time, when the toilet lid is opened, the seat ring will not be synchronously lifted. The same is true when closing the toilet lid. After the signal transceiver of the main body receives the synchronization signal of the signal transmitter on the foot switch, it first controls the locking tongue to extend forward to latch the seat ring, and then the seat ring will also synchronously fall when closing the toilet lid. If only the seat ring needs to be lowered without closing the toilet lid, first control the seat ring and the toilet lid to close synchronously, and then open the toilet lid separately.

[0016] The first rotating shaft and the second rotating shaft are respectively installed on the upper base and the lower base. The first rotating shaft and the second rotating shaft are not connected by a physical coupling, but transmit torque through the first magnetic coupling and the second magnetic coupling, without drilling holes in the toilet lid, making the installation process more convenient.

[0017] Preferably, the seat ring synchronization device includes a horizontally arranged base. An extension chamber is provided on the lower side of the base. A vertically arranged rotating shaft is provided in the extension chamber. A gear is provided at the lower end of the rotating shaft. A rack with a front-rear length direction and meshing with the gear is provided beside the gear in the extension chamber. A locking tongue extending forward and exceeding the extension chamber is provided at the front end of the rack. The upper end of the rotating shaft extends upward through the extension chamber and through the base. A horizontally arranged cross bar with a left-right length direction is provided at the upper end of the rotating shaft. Wiring terminals are provided at both ends of the cross bar in the length direction.

[0018] During installation, the base is set at the lower side of the toilet lid near the inner hole edge of the seat ring, so that when the toilet lid is closed, the position of the locking tongue is lower than the lower side of the seat ring, and a hole is drilled in the toilet lid so that the upper end of the rotating shaft can pass through the toilet lid from bottom to top and be located above the toilet lid. The drawstrings led out from the two wire winding boxes are respectively connected to the terminal posts on the corresponding left and right sides of the cross bar.

[0019] During use, when the signal transceiver receives the synchronization signal sent by the signal transmitter, one of the two wire winding boxes winds the wire and the other unwinds the wire. At this time, the rotating shaft connected to the cross bar will rotate under the drive of the drawstring, and the gear on the lower side of the rotating shaft will also rotate synchronously with the cross bar. The rotating gear drives the rack to move forward, so that the locking tongue extends forward to the lower side of the seat ring. At this time, when the toilet lid is opened, the seat ring will also be lifted synchronously under the drive of the locking tongue. If only the toilet lid is opened, the locking tongue is controlled to maintain the initial contracted state. At this time, when the toilet lid is opened, the seat ring will not be lifted synchronously. The same is true when closing the toilet lid. After the signal transceiver of the main body receives the synchronization signal from the signal transmitter on the foot switch, it first controls the locking tongue to extend forward to latch the seat ring, and then the seat ring will also fall synchronously when closing the toilet lid. If only the seat ring needs to be lowered without closing the toilet lid, it is to first control the seat ring and the toilet lid to close synchronously, and then open the toilet lid separately.

[0020] Preferably, a horizontally arranged outer frame is provided on the circumferential outer side of the main body of the host. The main body of the host is connected to the outer frame through several connecting columns, and the wire outlet end of the wire winding box passes through the outer frame.

[0021] The structure of the outer frame matches the upper part of the water tank. During installation, first remove the upper cover plate of the water tank, then directly install the outer frame on the upper side of the water tank, and install other components except the main body of the host to cooperate with the toilet lid and seat ring of the toilet. Such a structure makes the main body of the host located inside the outer frame, which is more beautiful.

[0022] Preferably, the human body sensor is arranged inside the main body of the host, and its probe extends to the front side of the outer frame.

[0023] The human body sensor adopts an in-built layout and does not need to protrude outside the water tank, making the whole more beautiful.

[0024] Preferably, the human body sensor is internally provided with a voice receiving and control module, and the voice receiving and control module is connected to the main controller.

[0025] Through the voice receiving and control module, the opening and closing of the toilet lid and seat ring can be controlled by voice instructions, making it more convenient to use.

[0026] Preferably, the human body sensor is internally provided with a face AI gender recognition module, and the face AI gender recognition module is connected to the main controller. Description of the Drawings

[0040] Embodiment 1:

[0041] Refer to Figures 1 - 5, a toilet lid control device, comprising a main body 1 for mounting on a toilet tank 8, a torsion spring reset device 2 and a seat ring synchronization device for mounting on a toilet lid 81, and an external foot switch 3. Inside the main body 1, there are two independently driven wire winding boxes 11 (the two wire winding boxes 11 are respectively driven by two independent motors 111), a main power supply, a main controller, a human body sensor 12, and a signal transceiver. The two wire winding boxes 11 are symmetrically arranged on the left and right in the middle area of the main body 1. A wire 13 is provided on each wire winding box 11, and the wire outlet directions of the two wire winding boxes 11 are both forward. The two wire winding boxes 11, the human body sensor 12, and the signal transceiver are all connected to the main power supply through the main controller. The foot switch 3 is internally provided with a signal transmitter and a corresponding power supply.

[0042] The seat ring synchronization device includes a horizontally arranged base 4. An extension bin 5 is provided on the lower side of the base 4. A vertically arranged rotating shaft 6 is provided inside the extension bin 5. A gear 51 is provided at the lower end of the rotating shaft 6. A rack 52 with a front-back running length direction and meshing with the gear 51 is provided beside the gear 51 in the position of the extension bin 5. A locking tongue 53 extending forward and exceeding the extension bin 5 is provided at the front end of the rack 52. The upper end of the rotating shaft 6 extends upward through the extension bin 5 and through the base 4. Two limiting blocks 63 arranged at intervals up and down are provided in the area above the base 4 corresponding to the position of the rotating shaft 6. A guiding component is provided behind the rotating shaft 6 at the upper side position of the base 4. The guiding component includes a frame 7. Two wire guiding wheel groups 71 / 72 arranged at intervals front and back are provided on the frame 7. The axis directions of the two wire guiding wheel groups 71 / 72 are both left-right. Each wire guiding wheel group 71 / 72 is provided with two coaxially arranged wire guiding wheels. The height of the lower horizontal tangent of the two wire guiding wheel groups 71 / 72 located at the front side is between the heights of the two limiting blocks 63.

[0043] The human body sensor 12 is internally provided with a voice receiving and control module, and the voice receiving and control module is connected to the main controller.

[0044] The human body sensor 12 is internally provided with a face AI gender recognition module, and the face AI gender recognition module is connected to the main controller.

[0045] Usage method of this device: Fix the main body 1 of this device on the water tank 8 of the toilet, set the torsion spring resetter 2 at the rear part on the upper side of the toilet lid 81, set the base 4 at the position on the lower side of the toilet lid 81 near the inner hole edge of the seat ring 82, so that the position of the locking tongue 53 is lower than the lower side of the seat ring 82 when the toilet lid 81 is closed, and make a hole in the toilet lid 81, so that the upper end of the rotating shaft 6 and the upper part of the guiding component can pass through the toilet lid 81 from bottom to top and be located above the toilet lid 81. The wire wheels on the same side of the two wire wheel groups 71 / 72 correspond to the pull wires 13 led out from the corresponding wire spool 11 on the corresponding side. The pull wire 13 of each wire spool 11 first clips into the upper side of the wire wheel group 71 at the rear side, then extends downward, and horizontally protrudes forward from the lower side of the wire wheel group 72 at the front side. The ends of the two pull wires 13 far away from the corresponding wire spools 11 are connected to form a U-shaped socket joint and are sleeved between the two limiting blocks of the rotating shaft. The ends of the two pull wires 13 far away from the corresponding wire spools 11 are connected to form a U-shaped socket joint and are sleeved between the two limiting blocks 63 of the rotating shaft 6. Set the foot switch 3 on the ground near the toilet.

[0046] When in use, when the human body sensor 12 detects someone approaching, the main controller controls the two wire reels 11 to wind the wires simultaneously. Under the action of the pulling wire 13, the toilet lid 81 is lifted upward. At this time, the torsion spring resetter 2 is torsionally deformed to form elastic potential energy for resetting the toilet lid 81. When the person who was originally within the monitoring range of the human body sensor 12 leaves, the main controller controls the two wire reels 11 to unwind the wires simultaneously. The elastic potential energy in the torsion spring resetter 2 is converted into kinetic energy to make the toilet lid 81 reset and close. If it is necessary to lift the seat ring 82, by operating the foot kick switch 3, the foot kick switch 3 is equivalent to an external remote control. The foot kick switch 3 sends a synchronization signal to the main body 1 of the host through a signal transmitter. When the signal transceiver receives the synchronization signal sent by the signal transmitter, one of the two wire reels 11 winds the wire and the other unwinds the wire. At this time, the U-shaped socket joint between the two limit blocks 63 sleeved on the rotating shaft 6 will drive the rotating shaft 6 to rotate. The gear 51 on the lower side of the rotating shaft 6 drives the rack 52 to move forward, so that the locking tongue 53 extends forward to the lower side of the seat ring 82. At this time, when the toilet lid 81 is opened, the seat ring 82 will also be lifted synchronously under the drive of the locking tongue 53. If only the toilet lid 81 is opened, the locking tongue 53 is controlled to maintain the initial contracted state. At this time, when the toilet lid 81 is opened, the seat ring 82 will not be lifted synchronously. When closing the toilet lid 81, the same principle applies. After the signal transceiver of the main body 1 of the host receives the synchronization signal from the signal transmitter on the foot kick switch 3, it first controls the locking tongue 53 to extend forward to latch the seat ring 82, and then when closing the toilet lid 81, the seat ring 82 will also fall synchronously. If only the seat ring 82 needs to be lowered without closing the toilet lid 81, it is to first control the seat ring 82 and the toilet lid 81 to close synchronously, and then open the toilet lid 81 alone. It is also possible to directly control only the opening of the toilet lid 81 or the synchronous lifting of the seat ring 82 when opening the toilet lid 81 and the closing of the toilet lid 81 through the foot kick switch 3 without the participation of the human body sensor 12.

[0047] Advantages of this device: This device is based on the existing traditional toilet and is installed on the existing toilet. There is no need to change the position of the original toilet, and the installation is convenient. After installing this device, it can automatically open the lid when a person comes and automatically close the lid when a person leaves. Through the voice receiving and control module, the opening and closing of the toilet lid 81 and the seat ring 82 can be controlled through voice commands. Through face gender recognition, it can make a judgment on whether to open the toilet lid 81 and the seat ring 82 synchronously or only the toilet lid 81 according to the differences when using the toilet for different genders, making the use more convenient.

[0048] Embodiment 2:

[0049] See Figures 1 - 3 、 Figure 6 、 Figure 7, a toilet lid control device, comprising a main body 1 for mounting on a toilet tank 8, a torsion spring reset device 2 and a seat ring synchronization device for mounting on a toilet lid 81, and an external foot switch 3. Inside the main body 1, there are two independently driven wire winding boxes 11 (the two wire winding boxes 11 are respectively driven by two independent motors 111), a main power supply, a main controller, a human body sensor 12, and a signal transceiver. The two wire winding boxes 11 are symmetrically arranged on the left and right in the middle area of the main body 1. A wire 13 is provided on each wire winding box 11, and the wire outlet directions of the two wire winding boxes 11 are both forward. The two wire winding boxes 11, the human body sensor 12, and the signal transceiver are all connected to the main power supply through the main controller. Inside the foot switch 3, there is a signal transmitter and a corresponding power supply.

[0050] The seat ring synchronization device includes a horizontally arranged base 4. An extension chamber 5 is provided on the lower side of the base 4. A vertically arranged rotating shaft 6 is provided inside the extension chamber 5. A gear 51 is provided at the lower end of the rotating shaft 6. A rack 52 with a front-back running length direction and meshing with the gear 51 is provided beside the gear 51 in the position inside the extension chamber 5. A locking tongue 53 extending forward and exceeding the extension chamber 5 is provided at the front end of the rack 52. The upper end of the rotating shaft 6 extends upward through the extension chamber 5 and passes through the base 4. Two vertically spaced limit blocks 63 are provided in the area above the base 4 corresponding to the position of the rotating shaft 6. A guiding component is provided behind the rotating shaft 6 at the upper side position of the base 4. The guiding component includes a frame 7. Two wire guiding wheel groups 71 / 72 arranged at intervals front and back are provided on the frame 7. The axis directions of the two wire guiding wheel groups 71 / 72 are both left-right. Each wire guiding wheel group 71 / 72 is provided with two coaxially arranged wire guiding wheels. The horizontal tangent height of the two wire guiding wheel groups 71 / 72 at the front side is between the heights of the two limit blocks 63.

[0051] A horizontally arranged outer frame 14 is provided on the circumferential outer side of the main body 1. The main body 1 is connected to the outer frame 14 through a plurality of connecting columns 141. The wire outlet end of the wire winding box 11 passes through the outer frame 14.

[0052] The human body sensor 12 is provided inside the main body 1, and its probe 121 extends to the front side of the outer frame 14.

[0053] The human body sensor 12 is internally provided with a voice receiving and control module, and the voice receiving and control module is connected to the main controller.

[0054] The human body sensor 12 is internally provided with a face AI gender recognition module, and the face AI gender recognition module is connected to the main controller.

[0055] Usage method of this device: The structure of the outer frame 14 matches the upper part of the water tank 8. During installation, first remove the upper cover plate of the water tank 8, then directly install the outer frame 14 on the upper side of the water tank 8. Set the torsion spring resetter 2 at the rear of the upper side of the toilet lid 81, and set the base 4 at the position of the lower side of the toilet lid 81 near the inner hole edge of the seat ring 82, so that the position of the locking tongue 53 is lower than the lower side of the seat ring 82 when the toilet lid 81 is closed. And make a hole in the toilet lid 81, so that the upper end of the rotating shaft 6 and the upper part of the guiding component can pass through the toilet lid 81 from bottom to top and be located above the toilet lid 81. The wire wheels on the same side of the two wire wheel groups 71 / 72 in the left-right direction correspond to the pull wires 13 led out from the corresponding wire spool 11 on one side. The pull wire 13 of each wire spool 11 first snaps into the upper side of the wire wheel group 71 at the rear, then extends downward, and horizontally protrudes forward from the lower side of the wire wheel group 72 located at the front side. The ends of the two pull wires 13 away from the corresponding wire spools 11 are connected to form a U-shaped socket joint and are sleeved between the two limit blocks of the rotating shaft. The ends of the two pull wires 13 away from the corresponding wire spools 11 are connected to form a U-shaped socket joint and are sleeved between the two limit blocks 63 of the rotating shaft 6. Set the foot switch 3 on the ground near the toilet.

[0056] When in use, when the human body sensor 12 detects someone approaching, the main controller controls the two wire reels 11 to take in the wire simultaneously. Under the action of the pulling wire 13, the toilet lid 81 is lifted upward. At this time, the torsion spring resetter 2 is twisted to form elastic potential energy for resetting the toilet lid 81. When the person who was originally within the monitoring range of the human body sensor 12 leaves, the main controller controls the two wire reels 11 to pay out the wire simultaneously. The elastic potential energy in the torsion spring resetter 2 is converted into kinetic energy to make the toilet lid 81 reset and close. If it is necessary to lift the toilet seat 82, by operating the foot kick switch 3, the foot kick switch 3 is equivalent to an external remote control. The foot kick switch 3 sends a synchronization signal to the main body 1 of the host through the signal transmitter. When the signal transceiver receives the synchronization signal sent by the signal transmitter, one of the two wire reels 11 takes in the wire and the other pays out the wire. At this time, the U-shaped socket joint between the two limit blocks 63 sleeved on the rotating shaft 6 will drive the rotating shaft 6 to rotate. The gear 51 on the lower side of the rotating shaft 6 drives the rack 52 to move forward, so that the locking tongue 53 extends forward to the lower side of the toilet seat 82. At this time, when the toilet lid 81 is opened, the toilet seat 82 will also be lifted synchronously under the drive of the locking tongue 53. If only the toilet lid 81 is opened, the locking tongue 53 is controlled to maintain the initial contracted state. At this time, when the toilet lid 81 is opened, the toilet seat 82 will not be lifted synchronously. When closing the toilet lid 81, the same principle applies. After the signal transceiver of the main body 1 of the host receives the synchronization signal from the signal transmitter on the foot kick switch 3, it first controls the locking tongue 53 to extend forward to latch the toilet seat 82, and then the toilet seat 82 will also fall synchronously when the toilet lid 81 is closed. If only the toilet seat 82 needs to be lowered without closing the toilet lid 81, first control the toilet seat 82 and the toilet lid 81 to close synchronously, and then open the toilet lid 81 alone. It is also possible to directly control only the opening of the toilet lid 81 or the synchronous lifting of the toilet seat 82 when the toilet lid 81 is opened and the closing of the toilet lid 81 through the foot kick switch 3 without the participation of the human body sensor 12.

[0057] Advantages of this device: This device is based on the existing traditional toilet and is installed on the existing toilet. There is no need to change the position of the original toilet, and the installation is convenient. After installing this device, it can automatically open the lid when a person comes and automatically close the lid when a person leaves. The main body 1 of the host is located inside the outer frame 14, and the human body sensor 12 adopts an in-built layout without protruding outside the water tank 8, making the overall appearance more beautiful. Through the voice receiving and control module, the opening and closing of the toilet lid 81 and the toilet seat 82 can be controlled by voice commands. Through face gender recognition, according to the differences when using the toilet for different genders, it can be judged whether to open the toilet lid 81 and the toilet seat 82 synchronously or only the toilet lid 81, making the use more convenient.

[0058] Embodiment Three:

[0059] See Figure 1 、 Figure 3 、 Figures 8 - 11, a toilet lid control device, including a main body 1 for installing on the toilet tank 8, a torsion spring reset device 2 and a seat ring synchronization device for installing on the toilet lid 81, and an external foot switch 3. Inside the main body 1, there are two independently driven wire winding boxes 11 (the two wire winding boxes 11 are respectively driven by two independent motors 111), a main power supply, a main controller, a human body sensor 12, and a signal transceiver. The two wire winding boxes 11 are symmetrically arranged on the left and right in the middle area of the main body 1. A wire 13 is provided on each wire winding box 11, and the wire outlet directions of the two wire winding boxes 11 are both forward. The two wire winding boxes 11, the human body sensor 12, and the signal transceiver are all connected to the main power supply through the main controller. The foot switch 3 is internally provided with a signal transmitter and a corresponding power supply.

[0060] The seat ring synchronization device includes a horizontally arranged upper base 41 and a lower base 42. The upper base 41 and the lower base 42 are arranged at an interval up and down. Inside the upper base 41, there is a first channel 411 vertically penetrating the upper base 4. Inside the first channel 411, there is a vertically arranged first rotating shaft 61. The lower end of the first rotating shaft 61 is flush with the lower end of the upper base 41 and is provided with a first magnetic coupling 611. The upper end of the first rotating shaft 61 extends beyond the upper base 41. At the position of the first rotating shaft 61, two limit blocks 63 are arranged at an interval up and down in the upper side area of the upper base 41. At the position of the lower base 42 corresponding to the first channel 411 of the upper base 41, there is a second channel 421 vertically penetrating the lower base 4. Inside the second channel 421, there is a vertically arranged second rotating shaft 62. The upper end of the second rotating shaft 62 is flush with the lower base 42 and is provided with a second magnetic coupling 521 matching the first magnetic coupling 611. An extension bin 5 is provided on the lower side of the lower base 42. The lower end of the second rotating shaft 6 penetrates into the extension bin 5 and is provided with a gear 51. Inside the extension bin 5, a rack 52 with a front-back running length direction and meshing with the gear 51 is arranged beside the gear 51. The front end of the rack 52 is provided with a locking tongue 53 extending forward and exceeding the extension bin 5. A guiding component is arranged on the upper side of the upper base 41 corresponding to the rear of the first rotating shaft 61. The guiding component includes a frame 7. On the frame 7, two wire guiding wheel groups 71 / 72 are arranged at an interval front and back. The axis directions of the two wire guiding wheel groups 71 / 72 are both left-right. Each wire guiding wheel group 71 / 72 is provided with two coaxially arranged wire guiding wheels. The height of the lower horizontal tangent of the two wire guiding wheel groups 71 / 72 located at the front side is between the heights of the two limit blocks 63.

[0061] The human body sensor 12 is internally provided with a voice receiving and control module, and the voice receiving and control module is connected to the main controller.

[0062] The human body sensor 12 is internally provided with a face AI gender recognition module, and the face AI gender recognition module is connected to the main controller.

[0063] Usage method of this device: Fix the main body 1 of this device on the water tank 8 of the toilet, set the torsion spring resetter 2 at the rear part on the upper side of the toilet lid 81, set the lower base 4 at the position on the lower side of the toilet lid 81 near the inner hole edge of the seat ring 82, so that the position of the locking tongue 53 is lower than the lower side of the seat ring 82 when the toilet lid 81 is closed, set the upper base 4 on the upper side of the toilet lid 81, and make the first magnetic coupling align with the second magnetic coupling. The wire wheels on the same side of the two wire wheel groups 71 / 72 in the left-right direction correspond to the pull wires 13 led out from the corresponding wire spool 11 on one side. The pull wire 13 of each wire spool 11 first clips into from the upper side of the wire wheel group 71 at the rear side, then extends downward, and horizontally protrudes forward from the lower side of the wire wheel group 72 at the front side. The ends of the two pull wires 13 away from the corresponding wire spools 11 are connected to form a U-shaped socket joint and are sleeved between the two limit blocks of the rotating shaft. The ends of the two pull wires 13 away from the corresponding wire spools 11 are connected to form a U-shaped socket joint and are sleeved between the two limit blocks 63 of the first rotating shaft 6. Set the foot switch 3 on the ground near the toilet.

[0064] When in use, when the human body sensor 12 detects someone approaching, the main controller controls the two wire reels 11 to take in the wire simultaneously. Under the action of the pulling wire 13, the toilet lid 81 is lifted upward. At this time, the torsion spring resetter 2 is torsionally deformed to form elastic potential energy for resetting the toilet lid 81. When the person who was originally within the monitoring range of the human body sensor 12 leaves, the main controller controls the two wire reels 11 to pay out the wire simultaneously. The elastic potential energy in the torsion spring resetter 2 is converted into kinetic energy to make the toilet lid 81 reset and close. If it is necessary to lift the seat ring 82, by operating the foot kick switch 3, the foot kick switch 3 is equivalent to an external remote control. The foot kick switch 3 sends a synchronization signal to the main body 1 of the host through a signal transmitter. When the signal transceiver receives the synchronization signal sent by the signal transmitter, one of the two wire reels 11 takes in the wire and the other pays out the wire. At this time, the U-shaped socket joint between the two limit blocks 63 sleeved on the first rotating shaft 6 will drive the first rotating shaft 6 to rotate. The first rotating shaft 6 transmits torque to the second rotating shaft 6 under the action of the first magnetic coupling and the second magnetic coupling. The gear 51 on the lower side of the second rotating shaft 6 drives the rack 52 to move forward, so that the locking tongue 53 extends forward to the lower side of the seat ring 82. At this time, when the toilet lid 81 is opened, the seat ring 82 will also be synchronously lifted under the drive of the locking tongue 53. If only the toilet lid 81 is opened, the locking tongue 53 is controlled to maintain the initial contracted state. At this time, when the toilet lid 81 is opened, the seat ring 82 will not be synchronously lifted. When closing the toilet lid 81, it is the same. After the signal transceiver of the main body 1 of the host receives the synchronization signal from the signal transmitter on the foot kick switch 3, it first controls the locking tongue 53 to extend forward to latch the seat ring 82, and then the seat ring 82 will also synchronously fall when closing the toilet lid 81. If only the seat ring 82 needs to be lowered without closing the toilet lid 81, it is to first control the seat ring 82 and the toilet lid 81 to close synchronously, and then the toilet lid 81 is separately opened. It is also possible to directly control only the opening of the toilet lid 81 or the synchronous lifting of the seat ring 82 when opening the toilet lid 81 and the closing of the toilet lid 81 through the foot kick switch 3 without the participation of the human body sensor 12.

[0065] Advantages of this device: This device is based on the existing traditional toilet and is installed on the existing toilet. There is no need to change the position of the original toilet, and the installation is convenient. After installing this device, the toilet lid can be automatically opened when a person comes and automatically closed when a person leaves. Through the voice receiving and control module, the opening and closing of the toilet lid 81 and the seat ring 82 can be controlled through voice commands. Through face gender recognition, according to the differences when using the toilet for different genders, it can be judged whether to open the toilet lid 81 and the seat ring 82 synchronously or only the toilet lid 81, making the use more convenient.

[0066] The first rotating shaft 6 and the second rotating shaft 6 are respectively installed on the upper base 4 and the lower base 4. The first rotating shaft 6 and the second rotating shaft 6 are not connected by a physical coupling, but transmit torque through the first magnetic coupling and the second magnetic coupling, eliminating the need to drill holes in the toilet lid 81 and making the installation process more convenient.

[0067] Embodiment 4:

[0068] Refer to Figure 1 、 Figure 2 、 Figure 12 、 Figure 13 There is a toilet lid control device, which includes a main body 1 for installing on the toilet tank 8, a torsion spring resetter 2 and a seat ring synchronization device for installing on the toilet lid 81, and an external foot switch 3. Inside the main body 1, there are two independently driven wire winding boxes 11 (the two wire winding boxes 11 are respectively driven by two independent motors 111), a main power supply, a main controller, a human body sensor 12, and a signal transceiver. The two wire winding boxes 11 are symmetrically arranged on the left and right in the middle area of the main body 1. A pull wire 13 is provided on each wire winding box 11, and the wire outlet directions of the two wire winding boxes 11 are both forward. The two wire winding boxes 11, the human body sensor 12, and the signal transceiver are all connected to the main power supply through the main controller. Inside the foot switch 3, there is a signal transmitter and a corresponding power supply.

[0069] The seat ring synchronization device includes a horizontally arranged base 4. An extension bin 5 is provided on the lower side of the base 4. A vertically arranged rotating shaft 6 is provided inside the extension bin 5. A gear 51 is provided at the lower end of the rotating shaft 6. A rack 52 with a front-back running length direction and meshing with the gear 51 is provided beside the gear 51 in the position inside the extension bin 5. A locking tongue 53 extending forward and exceeding the extension bin 5 is provided at the front end of the rack 52. The upper end of the rotating shaft 6 extends upward through the extension bin 5 and passes through the base 4. A horizontally arranged cross bar 63 with a left-right running length direction is provided at the upper end of the rotating shaft 6. Wiring terminals 64 are provided at both ends of the cross bar 63 in the length direction.

[0070] The human body sensor 12 is internally provided with a voice receiving and control module, and the voice receiving and control module is connected to the main controller.

[0071] The human body sensor 12 is internally provided with a face AI gender recognition module, and the face AI gender recognition module is connected to the main controller.

[0072] Usage method of this device: Fix the main body 1 of this device on the toilet tank 8, set the torsion spring resetter 2 at the rear part on the upper side of the toilet lid 81, set the base 4 at the position on the lower side of the toilet lid 81 near the inner hole edge of the seat ring 82, so that the position of the locking tongue 53 is lower than the lower side of the seat ring 82 when the toilet lid 81 is closed, and make a hole in the toilet lid 81 so that the upper end of the rotating shaft 6 can pass through the toilet lid 81 from bottom to top and be located above the toilet lid 81. The pull wires 13 led out from the two wire winding boxes 11 are respectively connected to the wiring terminals 64 on the corresponding left and right sides of the cross bar 63. Set the foot switch 3 on the ground near the toilet.

[0073] When in use, when the human body sensor 12 detects someone approaching, the main controller controls the two wire reels 11 to take in the wire simultaneously. Under the action of the pulling wire 13, the toilet lid 81 is lifted upward. At this time, the torsion spring resetter 2 is twisted to form an elastic potential energy for resetting the toilet lid 81. When the person who was originally within the monitoring range of the human body sensor 12 leaves, the main controller controls the two wire reels 11 to pay out the wire simultaneously. The elastic potential energy in the torsion spring resetter 2 is converted into kinetic energy to make the toilet lid 81 reset and close. If it is necessary to lift the seat ring 82, by operating the foot kick switch 3, the foot kick switch 3 is equivalent to an external remote control. The foot kick switch 3 sends a synchronization signal to the main body 1 of the host through a signal transmitter. When the signal transceiver receives the synchronization signal sent by the signal transmitter, one of the two wire reels 11 takes in the wire and the other pays out the wire. At this time, the rotating shaft 6 connected to the cross bar 63 will rotate under the drive of the pulling wire 13. The gear 51 on the lower side of the rotating shaft 6 will also rotate synchronously with the cross bar 63. The rotating gear 51 drives the rack 52 to move forward, so that the locking tongue 53 extends forward to the lower side of the seat ring 82. At this time, when the toilet lid 81 is opened, the seat ring 82 will also be lifted synchronously under the drive of the locking tongue 53. If only the toilet lid 81 is opened, the locking tongue 53 is controlled to maintain the initial contracted state. At this time, when the toilet lid 81 is opened, the seat ring 82 will not be lifted synchronously. When closing the toilet lid 81, the same is true. After the signal transceiver of the main body 1 of the host receives the synchronization signal from the signal transmitter on the foot kick switch 3, it first controls the locking tongue 53 to extend forward to latch the seat ring 82, and then when closing the toilet lid 81, the seat ring 82 will also fall synchronously. If only the seat ring 82 needs to be lowered without closing the toilet lid 81, first control the seat ring 82 and the toilet lid 81 to close synchronously, and then open the toilet lid 81 alone. It is also possible to directly control only the opening of the toilet lid 81 or the synchronous lifting of the seat ring 82 when opening the toilet lid 81 and the closing of the toilet lid 81 through the foot kick switch 3 without the participation of the human body sensor 12.

[0074] Advantages of this device: This device is based on the existing traditional toilet and is installed on the existing toilet. There is no need to change the position of the original toilet, and the installation is convenient. After installing this device, it can automatically open the lid when a person comes and automatically close the lid when a person leaves. Through the voice receiving and control module, the opening and closing of the toilet lid 81 and the seat ring 82 can be controlled through voice commands. Through face gender recognition, it is possible to make a judgment on whether to open the toilet lid 81 and the seat ring 82 synchronously or only the toilet lid 81 according to the differences when using the toilet for different genders, making it more convenient to use.

[0075] Supplementary description:

In this way, the length of the pulling wire can be changed manually. When there is a power outage, the toilet lid and the seat ring can be opened by winding the pulling wire through the wire reel. Similarly, by paying out the wire through the wire reel and hovering, the toilet lid and the seat ring can be closed.

[0077] 2. For Embodiments 1 to 3, after the ends of the two stay wires away from the corresponding wire spools are connected, not only can a U-shaped socket joint be formed to sleeved on the rotating shaft, but also it can be wound around the rotating shaft in the way of winding coils. This winding method can increase the friction force and has a better effect.
