Description

Cat Smart Toilet Seat Technical Field

[0001] This utility model relates to a cat defecation device, and more particularly to a smart cat toilet seat that can be organically integrated with the owner's toilet and achieve harmless treatment of cat excrement by reusing the functions of the owner's toilet. Background Technology

[0002] Current cat litter box solutions mainly include traditional litter boxes, smart litter boxes, and toilet trainers. Traditional litter boxes have drawbacks such as litter splattering, unpleasant odors, and bacterial growth; smart litter boxes pose safety risks and are generally expensive; toilet trainers are difficult to use and require a lot of time and effort. Their common flaw is that they all fail to effectively integrate cat waste disposal with the ideal waste disposal system—the owner's toilet.

[0003] Utility Model Content

[0004] The purpose of this invention is to overcome the aforementioned shortcomings of the existing technology and provide a smart toilet seat for cats. By seamlessly integrating with the owner's toilet, it reuses the toilet as a waste disposal terminal. Employing an automatic litter bowl movement system, when the cat is about to defecate, intelligent control technology instantly moves the litter bowl to avoid directing the cat's waste into the owner's toilet. This achieves improvements in hygiene, safety, and convenience.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a smart toilet seat for cats, comprising a main base and a top cover, suitable for placement on the upper edge of the owner's toilet seat. The main components are housed within the base, including a litter bowl for holding cat litter, a transmission mechanism, and a control system.

[0006] The transmission mechanism includes a litter bowl tray, a ball screw assembly, a transmission screw, a first rolling bearing, a second rolling bearing, and a transmission guide rail, which can convert rotational motion into horizontal linear movement and support the reciprocating translation of the litter bowl.

[0007] The control system includes a central processing unit and control panel serving as the control and power supply hub, a first sensor for detecting the cat's pre-defecation behavior, a second sensor for detecting the cat's post-defecation behavior, a DC motor, and a rechargeable lithium battery.

[0008] The central processing unit and control panel is a hardware assembly with control, drive and power management functions. Its core is the STM32H743VIT6 microcontroller (hereinafter referred to as "STM32 microcontroller"), and it integrates a motor drive module, a DC-DC buck regulator module and a main power switch.

[0009] The central processing unit and control panel, based on the cat's pre-defecation behavior signal transmitted from the first sensor, provide power to the DC motor and issue a command to control its forward rotation. Through the transmission mechanism, just before the cat defecates, the litter bowl is moved from the "normal position (A)" above the owner's toilet to the "avoidance position (B)" to hide instantly, allowing the cat's excrement to fall naturally into the owner's toilet. Based on the cat's post-defecation behavior signal transmitted from the second sensor, the DC motor is controlled to rotate in the reverse direction, moving the litter bowl back from the "avoidance position (B)" to the "normal position (A)".

[0010] This utility model is placed horizontally on the upper edge of the owner's toilet, and the two are connected as an organic whole. The former follows the cat's natural litter-digging instinct to defecate, while the latter reuses its own receiving and drainage functions, so that the cat's excrement may either remain briefly in the water in the owner's toilet or be flushed away immediately, thereby achieving automated and harmless treatment of cat excrement from the source.

[0011] The beneficial effects of this invention are that, by organically connecting with the owner's toilet, it handles cat excrement through a "real-time monitoring - instant avoidance - immediate flushing" method, achieving a leap from "independent processing" to "system integration." It effectively reduces odor emissions, essentially eliminates the hassle of cleaning litter boxes, and completely avoids the drawbacks of traditional litter boxes that easily breed bacteria, the safety hazards of smart litter boxes, and the excessive effort required for toilet training devices. It achieves a systematic solution to the shortcomings of existing technologies. Attached Figure Description

[0020] Figure 5 is a complete architecture block diagram of the control system of this utility model.

[0021] As shown in the figure, the system adopts a highly integrated modular design, with the central processing unit and control panel (11) as the core hub for control and power supply, working together with the sensing and execution units to form a clear signal flow, power flow and grounding reference.

[0022] Core Hub: The central processing unit and control panel (11) consists of four main internal functional modules. The STM32 microcontroller is the core of the system's intelligent decision-making; the motor drive module receives instructions from the microcontroller and drives the DC motor (12); the DC-DC step-down regulator module performs power conversion and distribution; and the main power switch controls the on / off state of the system's main power supply.

[0023] Energy path: The power from the rechargeable lithium battery (13) is fed into the DC-DC module after passing through its internal protection board and the main power switch. The DC-DC module outputs two independent power supplies: a 24V path dedicated to powering the power terminals of the motor drive module and the DC motor (12); and a 3.3V path serving as the digital logic power supply, providing unified power to the microcontroller, all sensors, and the logic terminals of the motor drive module. The system strictly adheres to the single-point grounding principle, and all grounding symbols (▼) in the figure are electrically interconnected to construct a unified common reference ground.

[0024] Signal sensing path: In the first sensor (9), the gravity sensor transmits the cat's pre-defecation behavior signal to the microcontroller through the I2C1 interface and the vibration and sound sensor transmits the signal through the DO interface. In the second sensor (10), the image sensor transmits the cat's post-defecation behavior signal to the microcontroller through the UART interface, the photosensitive sensor transmits the signal through the AO interface, and the odor sensor transmits the signal through the I2C2 interface.

[0025] Control Drive Path: After processing the sensed information, the STM32 microcontroller sends PWM (speed regulation) and DIR (direction) control signals to the motor drive module. The motor drive module modulates the 24V power supply accordingly and controls the DC motor (12) to perform precise start, stop, direction and speed actions through the two output terminals "M+" and "M-".

[0026] This block diagram fully and clearly reveals the specific circuit structure and connection relationships for realizing the intelligent control function of this utility model. Detailed Implementation

[0027] The present invention relates to a smart toilet seat for cats and its functions, which are achieved through the following methods.

[0028] (I) Physical structure and morphology.

[0029] The physical form of this utility model of a smart toilet seat for cats mainly consists of a main body base (1), a top cover (26), a litter bowl (2), and other components. It is generally flat and rectangular in shape, 45cm long, 39cm wide on one side (the opposite side is semi-circular), and 7cm high. The outer edge of the top cover (26) is slightly smaller than the inner edge of the upper opening of the base (1), and fits into the upper opening of the base (1). The bottom of the base (1) has an inner through hole (28) with a diameter of 16cm at an off-center position; the top cover (26) has an inner through hole (27) with a diameter of 12cm at an off-center position. The inner through hole (27) of the top cover and the inner through hole (28) of the bottom of the base are arranged vertically, with the top hole being smaller than the bottom hole, and are concentric with each other.

[0030] The litter bowl (2) (13cm in diameter and 6cm in depth) is set inside the base (1) and can be switched between the "normal position (A)" and the "avoidance position (B)" with the support of the transmission mechanism. When the litter bowl (2) is in the "normal position (A)", the inner hole (27) of the top cover and the inner hole (28) of the bottom of the base are blocked and closed by the litter bowl (2). The opening of the litter bowl (2) and the inner hole (27) of the top cover are in a "larger inside and smaller outside, concentric and basically flat" layout, presenting the appearance of a traditional litter box, for the cat to dig before defecating and bury after defecating. When the litter bowl (2) is in the "avoidance position (B)", the inner hole (27) of the top cover and the inner hole (28) of the bottom of the base are no longer blocked by the litter bowl (2) and are connected vertically, and the cat's excrement can fall smoothly through as a natural object.

[0031] The physical structure consisting of the base (1), top cover (26), litter bowl (2) and through hole, through the translational design of the litter bowl (2), lays the structural foundation for realizing the "instant avoidance" mechanism.

[0032] (ii) Mechanical transmission mechanism.

[0033] In this utility model of a smart toilet seat for cats, the litter bowl (2) is supported by a litter bowl tray (3), and the litter bowl tray (3) is fixedly connected to a ball screw assembly (4) to perform horizontal linear movement. The rotor of the DC motor (12) is fixedly connected to the transmission screw (5) through a coupling (14) to perform rotational movement; the ball screw assembly (4) is movably connected to the transmission screw (5) to convert the rotational movement into horizontal linear movement.

[0034] After receiving the control signal, the DC motor (12) starts and drives the transmission screw (5) to rotate through the coupling (14). The ball screw pair (4) and the transmission screw (5) convert the rotational motion into linear motion, thereby driving the cat litter bowl tray (3) and the cat litter bowl (2) to switch between the "normal position (A)" and the "avoidance position (B)".

[0035] The transmission mechanism, consisting of a DC motor (12), a ball screw pair (4), and a transmission screw (5), drives the cat litter bowl (2) to move through a power transmission chain of "motor rotation - screw transmission - linear motion", providing power support for realizing the "instant evasion" mechanism.

[0036] (III) Intelligent control system.

[0037] The intelligent control system of this cat-shaped smart toilet seat uses the central processing unit and control panel (11) as the control and power supply hub. This panel is a hardware assembly integrating intelligent decision-making, motor drive, and power management functions. The functions of the "central processing unit" are implemented by a microcontroller (e.g., an STM32 microcontroller); the "control panel" refers to the hardware entity that houses the microcontroller and integrates the motor drive module, DC-DC step-down regulator module, and main power switch. Together, they constitute the unified control and power supply hub.

[0038] 1. Integrated Power Management: This utility model adopts a highly integrated power management mode, consisting of a rechargeable lithium battery (13) (including its protection board) and a DC-DC step-down regulator module forming a two-stage power supply architecture. The rechargeable lithium battery (13) has overcharge, over-discharge and short-circuit protection functions. After the system is powered on, the power is first controlled by the main power switch and then input to the DC-DC step-down regulator module. This module outputs two independent power supplies: a 24V path is dedicated to the power section of the DC motor (12) and its drive module; the 3.3V path serves as a digital power node, supplying power to the STM32 microcontroller, all sensors and the logic section of the motor drive module.

[0039] The system strictly adheres to the single-point grounding principle, constructing a unified common reference ground. The negative terminal of the rechargeable lithium battery (13), the GND output terminal of the DC-DC step-down regulator module, the GND pin of the STM32 microcontroller, the GND terminals of all sensors, and the GND port of the motor drive module are all electrically connected to the common grounding point. This design provides a clean and stable reference potential for the power supply and signal loops, ensuring the accuracy of signal acquisition and the reliability of overall operation at the system level.

[0040] 2. Combined Sensor Sensing: All sensor power lines are routed from the digital 3.3V power supply node, separate from the signal lines, to ensure signal purity. The connection methods and trigger thresholds between each sensor and the STM32 microcontroller are as follows:

[0041] The first sensor (9) is used to detect the cat's litter-digging behavior before defecating. As shown in Figures 1 and 5, the gravity sensor MPU-6050 (I2C) is connected to the STM32 microcontroller via a 3-core cable (specifically SCL→PB8, SDA→PB9, GND), and the threshold can be a gravity change ≥10g. The vibration sensor SW-420 (DO) is connected to the STM32 microcontroller via a 2-core cable (specifically DO→PA0, GND), and the threshold can be a high output level (lasting ≥0.5 seconds). The sound sensor KY-038 (DO) is connected to the STM32 microcontroller via a 2-core cable (specifically DO→PA1, GND), and the threshold can be a high output level (lasting ≥0.5 seconds).

[0042] The second sensor (10) is used to sense the cat's post-defecation behavior. As shown in Figure 5, the OV2640 image sensor + ESP32-S3 CAM module (UART) is the preferred solution, and its connection is extremely simplified. It is connected to the STM32 microcontroller via a 2-core cable (specifically TX→PA2, GND). The threshold can be determined by the motion detection algorithm completed within the module. When the image activity within the preset range is detected to match the characteristics of the cat getting up or turning around, a trigger signal is output. The GL5528 photosensitive sensor (AO) is connected to the STM32 microcontroller via a 2-core cable [specifically AO→PA3-C (ADC input), GND]. The threshold can be determined by a significant increase in the analog output voltage (e.g., an increase of ≥50%). The odor sensor ENS160 (I2C) is connected to the STM32 microcontroller via a 3-core cable (specifically SCL→PB10, SDA→PB11, GND). The threshold is determined by a significant increase in the total volatile organic compound (TVOC) reading or air quality index (IAQ) that is consistent with the characteristics of excrement.

[0043] 3. Comprehensive Intelligent Decision-Making: The STM32 microcontroller serves as the core of the system's intelligent decision-making, and its internally embedded program forms a complete "perception-decision-execution" closed loop. The system continuously monitors sensor signals: when the first sensor (9) signal is triggered, the system is awakened from sleep mode; when the first sensor signal disappears, the STM32 microcontroller determines "litter removal is complete" and triggers the corresponding motor control sequence to move the litter bowl (2) from the normal position (A) to the avoidance position (B); when the second sensor (10) signal is triggered, the STM32 microcontroller determines "defecation is complete" and then triggers the motor's reverse rotation control sequence to reset the litter bowl (2). The STM32 microcontroller, by comprehensively scheduling all sensor information, generates start, stop, direction, speed, and delay commands for the DC motor (12) in an orderly manner, which is the core of realizing the entire automated operation.

[0044] 4. Reliable drive execution: The motor drive module integrated into the central processing unit and control panel (11) is the bridge between control commands and power output. It receives PWM (Pulse Width Modulation) and DIR (Direction) commands from the STM32 microcontroller through the control signal line, modulates the 24V power supply, and drives the DC motor (12) to rotate precisely at a predetermined speed and direction through the “M+” and “M-” output terminals. The direction of rotation is controlled by the drive DIR signal. The forward current is motor drive module → “M+” → DC motor (12) → “M-”, and the reverse current is motor drive module → “M-” → DC motor (12) → “M+”. The DC motor (12) drives the cat litter bowl tray (3) and cat litter bowl (2) to move precisely between the “normal position (A)” and the “avoiding position (B)” through the transmission mechanism such as the ball screw pair (4) with a pitch of 5mm and the transmission screw (5). The rated torque of the DC motor (12) is not less than 0.1N·m. Calculations show that the torque is sufficient to drive a 1.5kg cat litter bowl (2) assembly to move horizontally 15cm on the drive screw (5) at a speed of 1800rpm within 1 second.

[0045] 5. Orderly Workflow: When the cat digs in the litter box before urinating, the first sensor (9) is triggered, waking the system from its normal sleep state. When the cat finishes digging, the increased gravity, continuous vibration, and sound changes disappear. The first sensor (9) transmits this signal back to the STM32 microcontroller within 0.3 seconds. The STM32 microcontroller, through the motor drive module, controls the DC motor (12) to rotate clockwise for 1 second within 0.5 seconds, moving the litter bowl (2) 15cm from the "normal position (A)" to the "avoiding position (B)" within a total of 1.8 seconds. Within 1.8 seconds after the cat gets up and turns around after urinating, the second sensor (10) transmits signals such as image activity, light fluctuations, and odor changes back to the STM32 microcontroller. The STM32 microcontroller, through the motor drive module, controls the DC motor (12) to rotate counterclockwise for 1 second, resetting the litter bowl (2) to the "normal position (A)" for the cat to complete the burying behavior. Three minutes after completion, the intelligent system returns to sleep state.

[0046] Through the aforementioned structural logic encompassing power supply, sensing, decision-making, control, and execution, intelligent control and operation are achieved. The transmission mechanism and intelligent control system are deeply integrated to achieve a "real-time monitoring - instantaneous avoidance" mechanism.

[0047] Thus, this utility model forms a complete intelligent mechanical device—a smart toilet seat for cats. Its essential feature is that, at the critical moment before and after a cat defecates, the litter bowl (2) is moved and switched between the "normal position (A)" and the "avoidance position (B)".

[0048] The present invention is placed horizontally on the upper edge of the owner's toilet, and the two are connected and combined into an organic whole. The former, through the "real-time monitoring - instant avoidance" mechanism, moves the cat litter bowl (2) 15cm from the "normal position (A)" to the "avoidance position (B)" to hide, so that the cat's excrement falls naturally into the water in the owner's toilet; the latter also serves as the cat's excrement treatment terminal, making full use of its receiving and drainage functions, so that the cat's excrement either stays briefly in the water in the owner's toilet or is flushed away immediately. Thus, a linkage technology mechanism of "real-time monitoring - instant avoidance - immediate flushing" is established.

[0049] Therefore, it can effectively reduce odor emission, basically eliminate the trouble of cleaning cat litter, and completely avoid the drawbacks of traditional cat litter boxes that are prone to bacterial growth, smart cat litter boxes that pose safety hazards, and toilet training devices that consume a lot of energy, thus achieving a systematic solution to the defects of existing technologies.

[0050]

Example 1

[0051] Normally, cats defecate 1-2 times and urinate 2-3 times a day, each time lasting no more than 3 minutes. This invention will work for a maximum of about 15 minutes per day, spending most of the remaining time sleeping.

[0052] As shown in the attached diagram, when a cat steps onto the toilet seat and digs into the litter bowl (2) with its front paws, it generates gravity, vibration, and sound. The first sensor (9), fixed on the guide rail, transmits signals such as increased gravity, continuous vibration, and sound changes back to the central processing unit and control panel (11), waking the intelligent system from sleep mode. When the cat finishes digging, the increased gravity, continuous vibration, and sound changes disappear. The first sensor (9) transmits this signal back to the central processing unit and control panel (11) within 0.3 seconds. The central processing unit and control panel (11) sends a command to the DC motor (12) to rotate clockwise at 1800 rpm for 1 second within 0.5 seconds. The DC motor (12) and transmission mechanism move the tray (3) and litter bowl (2) from the "normal position (A)" to the "avoiding position (B)" within 1 second. Thus, the litter bowl (2) is moved 15cm away within a total of 1.8 seconds, and the cat's excrement naturally falls into the water in the owner's toilet.

[0053] Within approximately 2.5 seconds of completing defecation, the cat will stand up (when urinating) and turn around (when defecating) to attempt to bury the excrement in the litter box, thus the excrement has already fallen into the water. Within 1.8 seconds after the cat stands up and turns around, the second sensor (10) fixed to the edge of the through hole inside the top cover transmits signals such as image activity, light fluctuations, and odor changes back to the central processing unit and control panel (11). The central processing unit and control panel (11) send a command to the DC motor (12) to rotate counterclockwise at a speed of 1800 rpm for 1 second. The DC motor (12) and the transmission mechanism move the tray (3) and the litter bowl (2) from the "avoiding position (B)" back to the "normal position (A)" so that the cat can complete the litter burying behavior.

[0054] Three minutes after the cat finishes defecating and stops digging in the litter box to bury its feces, the intelligent system returns to sleep mode.

[0055] Example 1 shows the only time a cat scratches the litter box before defecating.

[0056]

Example 2

[0057] Example 2 shows a cat scratching its litter box several times (N times, or between 2 and 5 times) before defecating.

[0058] As shown in the attached diagram, when the cat steps onto the toilet seat and first digs into the litter bowl (2) with its front paws, gravity, vibration, and sound are generated. The first sensor (9), fixed on the guide rail, transmits signals such as increased gravity, continuous vibration, and sound changes back to the central processing unit and control panel (11), waking the intelligent system from sleep mode. When the cat finishes digging for the first time, the increased gravity, continuous vibration, and sound changes also disappear. The first sensor (9) transmits this signal back to the central processing unit and control panel (11) within 0.3 seconds. The central processing unit and control panel (11) sends a command to the DC motor (12) to rotate clockwise at 1800 rpm for 1 second within 0.5 seconds. The DC motor (12) and transmission mechanism move the tray (3) and litter bowl (2) from the "normal position (A)" to the "avoiding position (B)" within 1 second. Thus, the litter bowl (2) is moved 15cm away and hidden within a total of 1.8 seconds.

[0059] The cat may stop defecating because it feels uncomfortable, and will get up, turn around, and start digging in the litter box a second time. Within 1.8 seconds after the cat gets up and turns around, the second sensor (10) transmits signals such as image activity, light fluctuations, and odor changes back to the central processing unit and control panel (11). The central processing unit and control panel (11) send a command to the DC motor (12) to rotate counterclockwise at a speed of 1800 rpm for 1 second. Within 1 second, the DC motor (12) and the transmission mechanism move the tray (3) and the litter bowl (2) from the "avoiding position (B)" back to the "normal position (A)" for the cat to dig in the litter box a second time.

[0060] When the cat finishes digging in the litter box for the second time, the increased gravity, continued vibration, and the change in sound disappear. The first sensor (9) transmits this signal back to the central processing unit and control panel (11) within 0.3 seconds. The central processing unit and control panel (11) sends a command to the DC motor (12) to rotate clockwise at 1800 rpm for 1 second within 0.5 seconds. The DC motor (12) and transmission mechanism move the tray (3) and litter bowl (2) from the "normal position (A)" to the "hiding position (B)" within 1 second. Thus, the litter bowl (2) is moved 15cm in a total of 1.8 seconds, hiding for the second time, and the cat's excrement naturally falls into the water in the owner's toilet.

[0061] Within 1.8 seconds after the cat finishes defecating, gets up, and turns around, the second sensor (10) transmits signals such as image activity, light fluctuations, and odor changes back to the central processing unit and control panel (11). The central processing unit and control panel (11) send a command to the DC motor (12) to rotate counterclockwise at a speed of 1800 rpm for 1 second. The DC motor (12) and the transmission mechanism move the tray (3) and the litter bowl (2) from the "avoiding position (B)" back to the "normal position (A)" so that the cat can complete the litter digging and burying behavior.

[0062] Three minutes after the cat finishes defecating and stops digging in the litter box to bury its feces, the intelligent system returns to sleep mode.

[0063] The above describes the process of having the cat dig in the litter box twice before defecating.

[0064] The process of a cat digging in the litter box 3 to N times before defecating is repeated and cumulative, so it will not be described in detail.
