Description

Technical Field

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

[0002] A toilet is provided with a toilet lid and a seat ring. For a traditional toilet, the opening and closing of its toilet lid and 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 seat ring, due to the existing layout limitations in 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 difficult for construction in old communities.

[0003] In Chinese Patent CN205349039U, when a cover plate tongue matching a self-locking door buckle is inserted into the self-locking door buckle, it is locked. In the locked state, when pressing down continuously, it will be unlocked again. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an automatic control device for a toilet lid, which is a device installed on an existing traditional toilet. It can play the functions of automatically flipping the toilet lid and the seat ring, and is convenient to use.

[0005] To solve the above technical problem, the present invention provides an automatic control device for a toilet lid, including:

[0006] A main body of the host for installing on the toilet cistern;

[0007] A torsion spring reset device, a self-locking door buckle and a seat ring synchronization device for installing on the toilet lid;

[0008] An external foot switch;

[0009] The main body of the host is provided with an electric drum, a main power supply, a main controller, a human body sensor and a signal transceiver. The drum is arranged in the middle area of the main body of the host. A steel tape is arranged on the drum. An outlet for the steel tape to pass through is provided at a position corresponding to the drum on the front side of the main body of the host. A downwardly inclined guiding device is provided at a position corresponding to the outlet on the front side of the main body of the host. The guiding device includes a first guide wheel and a second guide wheel arranged at intervals up and down. The axial directions of the first guide wheel and the second guide wheel are both left and right. The first guide wheel is provided with a convex portion with a circular arc-shaped cross section on its circumference. The second guide wheel is provided with a circular arc-shaped recess on its circumference that matches the circular arc-shaped convex portion of the first guide wheel. The first guide wheel and the second guide wheel are cooperated up and down to form a circular arc-shaped channel with a concave middle between them. One end of the steel tape away from the drum passes through the outlet and the circular arc-shaped channel and is provided with a cover plate tongue matching the self-locking door buckle. The drum, 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;

[0010] When the human body sensor detects someone approaching, the main controller controls the reel to release the steel coil tape. The steel coil tape extends straight forward and downward after passing through the guiding device. When the cover plate tongue on the steel coil tape engages with the self-locking door buckle on the toilet lid, the locking is completed. The main controller controls the reel to reverse and retract the steel coil tape. During the retraction of the steel coil tape, the toilet lid moves upward synchronously with the steel coil tape to complete the opening operation of the toilet lid. The torsion spring resetter 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 reel to release the steel coil tape again. The elastic potential energy in the torsion spring resetter is converted into kinetic energy to make the toilet lid reset and close. When the toilet lid closes instantaneously, the steel coil tape reaches the position where the cover plate tongue engages with the self-locking door buckle, and the steel coil tape resumes straightness at this moment. Then the reel continues to release the steel coil tape outward, and the cover plate tongue moves downward under the pressure provided by the straight steel coil tape to trigger the unlocking mechanism of the self-locking door buckle, and the cover plate tongue and the self-locking door complete unlocking. Finally, the main controller controls the reel to retract the steel coil tape to complete the closing operation of the toilet lid.

[0011] For the sake of simplicity in explaining the problem, hereinafter, an automatic control device for a toilet lid described in the present invention will be simply referred to as this device.

[0012] Usage method of this device: Fix the main body of the host of this device on the water tank of the toilet, set the torsion spring resetter at the rear upper side of the toilet lid, install the seat ring synchronization device at a position on the toilet lid corresponding to the seat ring, set the self-locking door buckle at the front upper side of the toilet lid opposite to the guiding device on the front side of the main body of the host, and set the foot switch on the ground near the toilet.

[0013] During use, when the human body sensor detects someone approaching, the main controller controls the reel to release the steel coil tape. The steel coil tape extends straight forward and downward after passing through the guiding device. (The steel coil tape itself has elasticity, and this elasticity has a tendency to convert it from a wound and bent state to a straight state. Its principle is the same as that of a steel tape measure, that is, after the steel coil tape extends out of the main body of the machine from the reel and passes through the guiding device, the cross-section of the steel coil tape in the width direction presents a concave arc shape. This shape is equivalent to a reinforcing rib structure for the long strip-shaped steel coil tape extending outside the main body of the machine, keeping it in a straight state). When the cover plate tongue on the steel coil tape is combined with the self-locking door buckle on the toilet lid, the locking is completed. At this time, the main controller controls the reel to reverse and retract the steel coil tape. During the retraction of the steel coil tape, the toilet lid moves upward synchronously with the steel coil tape, completing the opening operation of the toilet lid. At the same time, the torsion spring resetter is stressed and twisted to form an 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 reel to release the steel coil tape again. Since the steel coil tape cannot maintain a straight state during the opening and closing process of the toilet lid, at this time, the elastic potential energy in the torsion spring resetter is converted into kinetic energy to make the toilet lid reset and close. When the toilet lid closes instantaneously, the steel coil tape just reaches the position where the cover plate tongue and the self-locking door buckle are just combined, that is, the steel coil tape resumes straightness at this moment. Then the reel continues to release the steel coil tape outward, and the cover plate tongue moves downward under the pressure provided by the straight steel coil tape, triggering the unlocking mechanism of the self-locking door buckle, and the cover plate tongue and the self-locking door complete the unlocking. Finally, the main controller controls the reel to retract the steel coil tape, completing the closing operation of the toilet lid. 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 machine through a signal transmitter. Since the seat ring synchronization device can control the seat ring and the toilet lid to act in coordination, when the main controller in the main body of the machine controls the reel to open the lid, it will send a 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 closed synchronously when the toilet lid is closed. It is also possible to directly control only the opening of the toilet lid or lift the seat ring synchronously when opening the toilet lid and close the toilet lid without the participation of the human body sensor through the foot kick switch.

[0014] Advantages of this device: Based on the existing traditional toilet, this device is installed on the existing toilet without changing the original position of the toilet, which is convenient for installation. After installing this device, it can automatically open the lid when a person comes and automatically close the lid when a person leaves, making it more convenient to use.

[0015] To achieve better use effects of this device, its preferred solutions are as follows:

[0016] Preferably, the seat ring synchronization device includes a synchronous electromagnetic lock. The upper side of the synchronous electromagnetic lock body is horizontal, and an extension part is provided on the lower side of the synchronous electromagnetic lock body. A lock tongue assembly extending horizontally forward is provided on the front side of the extension part. An electromagnetic lock power supply, a first signal receiver, and an electromagnetic lock controller are further provided in the synchronous electromagnetic lock body. The lock tongue assembly and the first signal receiver are connected to the electromagnetic lock power supply through the electromagnetic lock controller.

[0017] During installation, the synchronous electromagnetic lock is arranged at the inner hole edge of the toilet seat close to the lower part of the toilet cover, so that the position of the lock tongue assembly is lower than the lower side of the seat ring when the toilet cover is closed. When in use, when the first signal receiver receives the synchronous signal sent by the signal transceiver, the electromagnetic lock controller controls the lock tongue assembly to extend forward to the lower side of the seat ring. At this time, when the toilet cover is opened, the seat ring will also be synchronously lifted. If only the toilet cover is opened, the lock tongue assembly is controlled to maintain the initial contracted state. At this time, when the toilet cover is opened, the seat ring will not be synchronously lifted. The same is true when closing the toilet cover. The signal transceiver of the main body first sends a synchronous signal to the first signal receiver to control the lock tongue assembly to extend forward and latch the seat ring, and then the seat ring will also synchronously fall when the toilet cover is closed. If only the seat ring needs to be lowered without closing the toilet cover, it is to first control the seat ring and the toilet cover to close synchronously, and then open the toilet cover separately.

[0018] Preferably, the seat ring synchronization device includes a magnetic attraction assembly and an armature matching the magnetic attraction assembly. The magnetic attraction assembly includes an electromagnet, a magnetic attraction controller, a magnetic attraction power supply, and a second signal receiver. The electromagnet and the second signal receiver are connected to the magnetic attraction power supply through the magnetic attraction controller.

[0019] During installation, the magnetic attraction assembly is arranged at the edge of the upper side of the toilet cover, and the armature is arranged on the seat ring (embedded, attached to the upper side of the seat ring or arranged on the lower side of the seat ring), and the position is directly opposite to the magnetic attraction assembly. When in use, when the second signal receiver receives the synchronous signal sent by the signal transceiver of the main body, the electromagnet is energized and attracted to the armature. At this time, when the toilet cover is opened, the seat ring will also be synchronously lifted. If only the toilet cover is opened, the electromagnet is controlled not to be energized. At this time, when the toilet cover is opened, the seat ring will not be synchronously lifted. The same is true when closing the toilet cover. The signal transceiver of the main body first sends a synchronous signal to the second signal receiver to control the electromagnet to attract the armature, and then the seat ring will also synchronously fall when the toilet cover is closed. If only the seat ring needs to be lowered without closing the toilet cover, it is to first control the seat ring and the toilet cover to close synchronously, and then open the toilet cover separately.

[0020] Preferably, a horizontally arranged outer frame body is provided on the circumferential outer side of the main body. The main body is connected to the outer frame body through a plurality of connecting columns. The outlet on the winding drum for the steel coil belt to pass through penetrates the outer frame body.

[0021] The outer frame structure matches the upper part of the water tank. During installation, first remove the upper side 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, so that it cooperates 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 internal installation layout, without protruding outside the water tank, and the overall appearance is 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 commands, 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.

[0027] Through face gender recognition, it is possible to make a judgment on whether to open the toilet lid and seat ring simultaneously or only the toilet lid according to the differences in using the toilet for different genders. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] For the following three embodiments, including the host body 1, the synchronous electromagnetic lock 6, the magnetic attraction component 8, and the foot switch 4, they are all equipped with a power supply (which can be a built-in power supply or an external power supply), a controller, and a signal receiver / transmitter. These electronic components are all existing mature technologies. When making products, most of them are purchased materials and then fired on a circuit board. The specific placement method and the design of the circuit part can be flexibly adapted by those skilled in the art as needed, and this is not the inventive point of the present invention. Therefore, in the accompanying drawings, the above structures are omitted or schematically expressed, and the specific structure is not shown.

[0038] Example 1:

[0039] See also Figures 1 - 5 , a toilet lid automatic control device, comprising: a host body 1 for installation on a toilet water tank 5; a torsion spring returner 2, a self-locking door catch 3 and a seat ring 52 synchronization device for installation on a toilet lid 51; an external foot kick switch 4; an electric reel 11 (the electric reel 11 is driven by a motor 14), a main power supply, a main controller, a human body sensor 12, and a signal transceiver are provided in the host body 1. The reel 11 is provided in the middle area of the host body 1, and a steel belt 111 is provided on the reel 11. An outlet for the steel belt 111 to pass through is provided at the front side of the host body 1 corresponding to the reel 11, and a downwardly inclined guide device 13 is provided at the front side of the host body 1 corresponding to the outlet, and the guide device 13 includes a first reel 11 arranged at an upper and lower intervals. A guide wheel 131 and a second guide wheel 132 are provided. The first guide wheel 131 and the second guide wheel 132 are axially oriented to the left and right. The first guide wheel 131 is circumferentially provided with a protrusion with an arc-shaped cross-section. The second guide wheel 132 is circumferentially provided with an arc-shaped recess with a cross-section matching the arc-shaped protrusion of the first guide wheel 131. The first guide wheel 131 and the second guide wheel 132 cooperate with each other to form a circular arc-shaped channel 133 with a concave middle part therebetween. The end of the steel roll bag away from the reel 11 passes through the outlet and the circular arc channel 133 and is provided with a cover tongue 31 matching the self-locking door buckle 3. The reel 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 4 is internally provided with a signal transmitter and a corresponding power supply.

[0040] The described seat ring 52 synchronization device includes a synchronous electromagnetic lock 6. The upper side of the body of the synchronous electromagnetic lock 6 is horizontal, and an extension part 61 is provided on the lower side of the body of the synchronous electromagnetic lock 6. A locking tongue assembly 62 extending horizontally forward is provided on the front side of the extension part 61. An electromagnetic lock power supply, a first signal receiver, and an electromagnetic lock controller are also provided inside the body of the synchronous electromagnetic lock 6. The locking tongue assembly 62 and the first signal receiver are connected to the electromagnetic lock power supply through the electromagnetic lock controller.

[0041] The described 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.

[0042] The described 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.

[0043] Usage method of this device: Fix the main body 1 of this device on the water tank 5 of the toilet, set the torsion spring resetter 2 at the rear part on the upper side of the toilet lid 51, set the synchronous electromagnetic lock 6 at a position near the inner hole edge of the seat ring 52 at the lower part of the toilet lid 51, so that the position of the locking tongue assembly 62 is lower than the lower side of the seat ring 52 when the toilet lid 51 is closed. Set the self-locking door buckle 3 at the front part on the upper side of the toilet lid 51 opposite to the guiding device 13 on the front side of the main body 1 of the device, and set the foot switch 4 on the ground near the toilet.

[0044] When in use, when the human body sensor 12 detects someone approaching, the main controller controls the reel 11 to release the steel coil tape 111. The steel coil tape 111 extends straight forward and downward after passing through the guiding device 13. (The steel coil tape 111 itself has elasticity, and this elasticity has a tendency to convert it from the bent state of winding to the straight state. Its principle is the same as that of a steel tape measure, that is, the steel coil tape 111 extends out of the main body 1 of the machine from the reel 11 and passes through the guiding device 13. The cross-section of the steel coil tape 111 in the width direction presents a concave arc shape. This shape is equivalent to a reinforcing rib structure for the long strip-shaped steel coil tape 111 extending out of the main body 1 of the machine, keeping it in a straight state). When the cover tongue 31 on the steel coil tape 111 is combined with the self-locking door buckle 3 on the toilet lid 51, the locking is completed. At this time, the main controller controls the reel 11 to reverse and retract the steel coil tape 111. During the retraction process of the steel coil tape 111, the toilet lid 51 moves upward synchronously with the steel coil tape 111, completing the opening operation of the toilet lid 51. At the same time, the torsion spring reset device 2 is torsionally stressed to form an elastic potential energy for resetting the toilet lid 51. When the person who was originally within the monitoring range of the human body sensor 12 leaves, the main controller controls the reel 11 to release the steel coil tape 111 again. Since the steel coil tape 111 cannot maintain a straight state during the opening and closing process of the toilet lid 51, at this time, the elastic potential energy in the torsion spring reset device 2 is converted into kinetic energy to make the toilet lid 51 reset and close. When the toilet lid 51 closes instantaneously, the steel coil tape 111 just reaches the position where the cover tongue 31 and the self-locking door buckle 3 are just combined, that is, the steel coil tape 111 resumes straightness at this moment. Then the reel 11 continues to release the steel coil tape 111 outward. The cover tongue 31 moves downward under the pressure provided by the straight steel coil tape 111, triggering the unlocking mechanism of the self-locking door buckle 3, and the cover tongue 31 and the self-locking door complete unlocking. Finally, the main controller controls the reel 11 to retract the steel coil tape 111, completing the closing operation of the toilet lid 51. If it is necessary to lift the seat ring 52, by operating the foot switch 4, the foot switch 4 is equivalent to an external remote control. The foot switch 4 sends a synchronization signal to the main body 1 of the machine through a signal transmitter. When the first signal receiver receives the synchronization signal sent by the signal transceiver, the electromagnetic lock controller controls the lock tongue assembly 62 to extend forward to the lower side of the seat ring 52. At this time, when the toilet lid 51 is opened, the seat ring 52 will also be lifted synchronously under the drive of the lock tongue assembly 62. If only the toilet lid 51 is opened, the lock tongue assembly 62 is controlled to maintain the initial contracted state. At this time, when the toilet lid 51 is opened, the seat ring 52 will not be lifted synchronously. Similarly, when closing the toilet lid 51, the signal transceiver of the main body 1 of the machine first sends a synchronization signal to the first signal receiver, controlling the lock tongue assembly 62 to extend forward to latch the seat ring 52, and then the seat ring 52 will also fall synchronously when the toilet lid 51 is closed. If only the seat ring 52 needs to be lowered without closing the toilet lid 51, first control the seat ring 52 and the toilet lid 51 to close synchronously, and then open the toilet lid 51 separately.It is also possible to directly control only the toilet lid 51 to open, or when opening the toilet lid 51, synchronously lift the seat ring 52 and close the toilet lid 51 through the foot kick switch 4 without the participation of the human body sensor 12.

[0045] Advantages of this device: Based on the existing traditional toilet, this device is installed on the existing toilet without changing the position of the original toilet, which is convenient to install. 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. Through the voice receiving and control module, the opening and closing of the toilet lid 51 and the seat ring 52 can be controlled by voice commands. Through face gender recognition, it is possible to make a judgment on whether to open the toilet lid 51 and the seat ring 52 synchronously or only the toilet lid 51 according to the differences when using the toilet for different genders, making it more convenient to use.

The second guide wheel 132 is provided with a circular arc-shaped recess on the circumference whose cross section matches the circular arc-shaped convex portion of the first guide wheel 131. The first guide wheel 131 and the second guide wheel 132 cooperate up and down to form a circular arc-shaped channel 133 with a concave middle between them. One end of the steel tape away from the drum 11 passes through the outlet and the circular arc-shaped channel 133 and is provided with a cover plate tongue 31 that matches the self-locking door buckle 3. The drum 11, the human body sensor 12, and the signal transceiver are all connected to the main power supply through the main controller. The foot kick switch 4 is internally provided with a signal transmitter and a corresponding power supply.

[0048] The described seat ring 52 synchronization device includes a synchronization electromagnetic lock 6. The upper side of the body of the synchronization electromagnetic lock 6 is horizontal, and an extension part 61 is provided on the lower side of the body of the synchronization electromagnetic lock 6. A locking tongue assembly 62 extending horizontally forward is provided on the front side of the extension part 61. An electromagnetic lock power supply, a first signal receiver, and an electromagnetic lock controller are also provided inside the body of the synchronization electromagnetic lock 6. The locking tongue assembly 62 and the first signal receiver are connected to the electromagnetic lock power supply through the electromagnetic lock controller.

[0049] A horizontally arranged outer frame 7 is provided on the circumferential outer side of the main body 1 of the host. The main body 1 of the host is connected to the outer frame 7 through a plurality of connecting columns 71. The guiding device 13 passes through the outer frame 7.

[0050] The described human body sensor 12 is provided inside the main body 1 of the host, and its probe 121 extends to the front side of the outer frame 7.

[0051] The described 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.

[0052] The described 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.

[0053] Usage method of this device: First, remove the upper cover plate of the water tank 5, then directly install the outer frame 7 on the upper side of the water tank 5, set the torsion spring resetter 2 at the rear part on the upper side of the toilet lid 51, set the synchronization electromagnetic lock 6 at the position near the inner hole edge of the seat ring 52 at the lower part of the toilet lid 51, so that the position of the locking tongue assembly 62 is lower than the lower side of the seat ring 52 when the toilet lid 51 is closed. Set the self-locking door buckle 3 at the front part on the upper side of the toilet lid 51 opposite to the guiding device 13 on the front side of the main body 1 of the host, and set the foot switch 4 on the ground near the toilet.

[0054] When in use, when the human body sensor 12 detects that someone is approaching, the main controller controls the reel 11 to release the steel coil tape 111. The steel coil tape 111 extends straight forward and downward after passing through the guiding device 13. (The steel coil tape 111 itself has elasticity, and this elasticity has a tendency to convert it from the bent state of winding to the straight state. Its principle is the same as that of a steel tape measure, that is, the steel coil tape 111 extends from the reel 11 out of the main body 1 and then passes through the guiding device 13. The cross-section of the steel coil tape 111 in the width direction presents a concave arc shape. This shape is equivalent to a reinforcing rib structure for the long strip-shaped steel coil tape 111 extending out of the main body 1 of the machine, enabling it to maintain a straight state). When the cover plate tongue 31 on the steel coil tape 111 is combined with the self-locking door buckle 3 on the toilet lid 51, the locking is completed. At this time, the main controller controls the reel 11 to reverse and retract the steel coil tape 111. During the retraction process of the steel coil tape 111, the toilet lid 51 moves upward synchronously with the steel coil tape 111, completing the opening operation of the toilet lid 51. At the same time, the torsion spring resetter 2 is torsionally stressed to form an elastic potential energy for resetting the toilet lid 51. When the person who was originally within the monitoring range of the human body sensor 12 leaves, the main controller controls the reel 11 to release the steel coil tape 111 again. Since the steel coil tape 111 cannot maintain a straight state during the opening and closing process of the toilet lid 51, at this time, the elastic potential energy in the torsion spring resetter 2 is converted into kinetic energy to make the toilet lid 51 reset and close. When the toilet lid 51 closes instantaneously, the steel coil tape 111 just reaches the position where the cover plate tongue 31 and the self-locking door buckle 3 are just combined, that is, the steel coil tape 111 resumes straightness at this moment. Then the reel 11 continues to release the steel coil tape 111 outward. The cover plate tongue 31 moves downward continuously under the pressure provided by the straight steel coil tape 111, triggering the unlocking mechanism of the self-locking door buckle 3, and the cover plate tongue 31 and the self-locking door complete unlocking. Finally, the main controller controls the reel 11 to retract the steel coil tape 111, completing the closing operation of the toilet lid 51. If it is necessary to lift the seat ring 52, by operating the foot kick switch 4, the foot kick switch 4 is equivalent to an external remote control. The foot kick switch 4 sends a synchronization signal to the main body 1 of the machine through the signal transmitter. When the first signal receiver receives the synchronization signal sent by the signal transceiver, the electromagnetic lock controller controls the lock tongue assembly 62 to extend forward to the lower side of the seat ring 52. At this time, when the toilet lid 51 is opened, the seat ring 52 will also be lifted synchronously under the drive of the lock tongue assembly 62. If only the toilet lid 51 is to be opened, the lock tongue assembly 62 is controlled to maintain the initial contracted state. At this time, when the toilet lid 51 is opened, the seat ring 52 will not be lifted synchronously. Similarly, when closing the toilet lid 51, the signal transceiver of the main body 1 of the machine first sends a synchronization signal to the first signal receiver to control the lock tongue assembly 62 to extend forward to latch the seat ring 52, and then the seat ring 52 will also fall synchronously when the toilet lid 51 is closed. If only the seat ring 52 needs to be lowered without closing the toilet lid 51, then the seat ring 52 and the toilet lid 51 are first controlled to close synchronously, and then the toilet lid 51 is separately opened.It is also possible to directly control only the opening of the toilet lid 51, or to synchronously lift the seat ring 52 when opening the toilet lid 51 and close the toilet lid 51 through the foot kick switch 4 without the participation of the human body sensor 12.

[0055] Advantages of this device: Based on the existing traditional toilet, this device is installed on the existing toilet without changing the position of the original toilet, which is convenient for installation. After installing this device, the toilet lid can be automatically opened when a person approaches and automatically closed when a person leaves, making it more convenient to use. The main body 1 of the host is located inside the outer frame 7 and is installed on the water tank 5, with a stronger overall sense. The human body sensor 12 adopts an in-built layout and does not need to protrude outside the water tank 5, making the overall appearance more beautiful. Through the voice receiving and control module, the opening and closing of the toilet lid 51 and the seat ring 52 can be controlled by voice commands. Through face gender recognition, it is possible to make a judgment on whether to open the toilet lid 51 and the seat ring 52 synchronously or only the toilet lid 51 according to the differences when using the toilet for different genders, making it more convenient to use.

[0056] Embodiment Three:

[0057] See Figure 1 、 Figure 5 、 Figure 8 、 Figure 9 A toilet lid automatic control device, comprising: a main body 1 of the host for installing on the toilet water tank 5; a torsion spring reset device 2, a self-locking door buckle 3 and a seat ring 52 synchronization device for installing on the toilet lid 51; an external foot kick switch 4; the main body 1 of the host is provided with an electric winding drum 11 (the electric winding drum 11 is driven by a motor 14), a main power supply, a main controller, a human body sensor 12, and a signal transceiver. The winding drum 11 is arranged in the middle area of the main body 1 of the host. A steel tape 111 is provided on the winding drum 11. An outlet for the steel tape 111 to pass through is provided at the front side position of the main body 1 of the host corresponding to the winding drum 11. A downwardly inclined guiding device 13 is provided at the front side position of the main body 1 of the host corresponding to the outlet. The guiding device 13 includes a first guide wheel 131 and a second guide wheel 132 arranged at intervals up and down. The axial directions of the first guide wheel 131 and the second guide wheel 132 are both left and right. The first guide wheel 131 is provided with a convex portion with a circular arc-shaped cross section on its circumference. The second guide wheel 132 is provided with a circular arc-shaped recess on its circumference that matches the circular arc-shaped convex portion of the first guide wheel 131. The first guide wheel 131 and the second guide wheel 132 are cooperated up and down to form a circular arc-shaped channel 133 with a concave middle part between them. One end of the steel tape away from the winding drum 11 passes through the outlet and the circular arc-shaped channel 133 and is provided with a cover plate tongue 31 that matches the self-locking door buckle 3. The winding drum 11, the human body sensor 12, and the signal transceiver are all connected to the main power supply through the main controller. The foot kick switch 4 is internally provided with a signal transmitter and a corresponding power supply.

[0058] The described seat ring 52 synchronization device includes a magnetic attraction component 8 and an armature 81 that matches the magnetic attraction component 8. The magnetic attraction component 8 includes an electromagnet, a magnetic attraction controller, a magnetic attraction power supply, and a second signal receiver. The electromagnet and the second signal receiver are connected to the magnetic attraction power supply through the magnetic attraction controller.

[0059] The described 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.

[0060] The described 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.

[0061] Usage method of this device: Fix the main body 1 of this device on the water tank 5 of the toilet, set the torsion spring resetter 2 at the rear part on the upper side of the toilet lid 51, set the magnetic attraction component 8 at a position near the edge on the upper side of the toilet lid 51, and set the armature 81 on the seat ring 52 (embedded, attached to the upper side of the seat ring 52 or arranged on the lower side of the seat ring 52), with the position directly opposite to the magnetic attraction component 8. Set the self-locking door buckle 3 at a position on the upper front part of the toilet lid 51 directly opposite to the guiding device 13 on the front side of the main body 1 of the device, and set the foot kick switch 4 on the ground near the toilet.

[0062] In use, when the human body sensor 12 detects someone approaching, the main controller controls the reel 11 to release the steel coil tape 111. The steel coil tape 111 extends straight forward and downward after passing through the guiding device 13. (The steel coil tape 111 itself has elasticity, and this elasticity has a tendency to convert it from a wound and bent state to a straight state. Its principle is the same as that of a steel tape measure, that is, the steel coil tape 111 extends from the reel 11 out of the main body 1 of the host and then passes through the guiding device 13. The cross-section of the steel coil tape 111 in the width direction presents a concave arc shape. This shape is equivalent to a reinforcing rib structure for the long strip-shaped steel coil tape 111 extending outside the main body 1 of the host, enabling it to maintain a straight state). When the cover plate tongue 31 on the steel coil tape 111 is combined with the self-locking door buckle 3 on the toilet lid 51, the locking is completed. At this time, the main controller controls the reel 11 to reverse and retract the steel coil tape 111. During the retraction process of the steel coil tape 111, the toilet lid 51 moves upward synchronously with the steel coil tape 111, completing the opening operation of the toilet lid 51. At the same time, the torsion spring resetter 2 is torsionally stressed to form elastic potential energy for resetting the toilet lid 51. When the person who was originally within the monitoring range of the human body sensor 12 leaves, the main controller controls the reel 11 to release the steel coil tape 111 again. Since the steel coil tape 111 cannot maintain a straight state during the opening and closing process of the toilet lid 51, at this time, the elastic potential energy in the torsion spring resetter 2 is converted into kinetic energy to make the toilet lid 51 reset and close. When the toilet lid 51 closes instantaneously, the steel coil tape 111 just reaches the position where the cover plate tongue 31 and the self-locking door buckle 3 are just combined, that is, the steel coil tape 111 resumes straightness at this moment. Then the reel 11 continues to release the steel coil tape 111 outward, and the cover plate tongue 31 moves downward under the pressure provided by the straight steel coil tape 111, triggering the unlocking mechanism of the self-locking door buckle 3, and the cover plate tongue 31 and the self-locking door complete unlocking. Finally, the main controller controls the reel 11 to retract the steel coil tape 111, completing the closing operation of the toilet lid 51. If it is necessary to lift the seat ring 52, by operating the foot kick switch 4, the foot kick switch 4 is equivalent to an external remote control. The foot kick switch 4 sends a synchronization signal to the main body 1 of the host through a signal transmitter. When the second signal receiver receives the synchronization signal sent by the signal transceiver of the main body 1 of the host, the electromagnet is energized and attracted to the armature 81. At this time, the toilet lid 51 is opened, and the seat ring 52 will also be lifted synchronously. If only the toilet lid 51 is to be opened, the electromagnet is controlled not to be energized. At this time, when the toilet lid 51 is opened, the seat ring 52 will not be lifted synchronously. When closing the toilet lid 51, similarly, the signal transceiver of the main body 1 of the host first sends a synchronization signal to the second signal receiver to control the electromagnet to be attracted to the armature 81, and then when closing the toilet lid 51, the seat ring 52 will also fall synchronously. If only the seat ring 52 needs to be lowered without closing the toilet lid 51, first control the seat ring 52 and the toilet lid 51 to close synchronously, and then separately open the toilet lid 51. It is also possible to directly control only the opening of the toilet lid 51 or the synchronous lifting of the seat ring 52 when opening the toilet lid 51 and the closing of the toilet lid 51 through the foot kick switch 4 without the participation of the human body sensor 12.

[0063] Advantages of this device: This device is based on the existing traditional toilet and is installed on the existing toilet without changing the position of the original toilet, which is convenient to install. 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. Through the voice receiving and control module, the opening and closing of the toilet lid 51 and the seat ring 52 can be controlled by voice commands. Through face gender recognition, according to the differences when using the toilet for different genders, it can be determined whether to open the toilet lid 51 and the seat ring 52 synchronously or only open the toilet lid 51, making it more convenient to use.
