Description

Technical Field

[0001] This invention belongs to the field of pet breeding technology, and specifically relates to a multifunctional self-cleaning and odorless pet dog toilet. Background Technology

[0002] With the rapid increase in pet-owning households, daily pet care has become a common pain point. Existing solutions are mostly single-function, independent devices, such as automatic feeders, water fountains, and traditional pet toilets. These devices are scattered, cumbersome to operate, and cannot form an efficient and coherent care process.

[0003] Specifically, traditional pet toilets rely on manual cleaning, which is inconvenient and poses significant hygiene risks. Feeding and watering equipment also requires frequent cleaning and maintenance, increasing the burden on owners. Furthermore, existing equipment lacks effective mechanisms to contain and treat odors from excrement, easily affecting indoor air quality. In terms of exercise and companionship, existing toys are often insufficiently intelligent, failing to meet the interactive needs of pets.

[0004] Overall, current pet care equipment suffers from low integration, insufficient automation, complex cleaning and maintenance, and poor odor control, forcing pet owners to invest significant time and energy in daily care. Therefore, the market urgently needs a comprehensive care system that is highly integrated, intelligently linked, and provides a one-stop solution for pets' core needs such as eating, drinking, defecation, and activity, while also achieving automatic cleaning, effective deodorization, and improved living experience for both humans and pets. Summary of the Invention

[0005] To address the aforementioned issues, this article primarily provides a multifunctional, self-cleaning, odorless pet toilet that can automatically clean, effectively deodorize, and enhance the living experience for both humans and pets.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows.

[0007] A multifunctional self-cleaning, odorless pet toilet, characterized by comprising:

[0008] The bottom shell contains a transmission track and a cleaning system. The transmission track is used to provide a standing platform for the pet, and the cleaning system is used to clean dirt from the surface of the transmission track.

[0009] The upper shell is located above the bottom shell and is detachably connected to the bottom shell. The upper shell is equipped with a sensing system, a feeding system, an interaction system, a deodorizing system, and a storage system. The sensing system is used to identify the pet's status, the feeding system is used to feed the pet, the interaction system is used to interact with the pet and play guidance commands, the deodorizing system is used to ensure that there are no odors in the surrounding environment of the device, and the storage system is used to store corresponding consumables.

[0010] This invention enables pets to function as treadmills by controlling the operation of a conveyor belt when they need exercise. A sensing system identifies the pet's status to operate different modes. An interactive system allows for remote communication with the pet or issuing commands such as eating, running, and toileting. When there is dirt on the surface of the conveyor belt, a cleaning system cleans the surface of the conveyor belt.

[0011] By incorporating sensing and feeding systems into the bottom and top shells, this product breaks through the limitations of existing pet care equipment, which suffers from single-function and fragmented scenarios. It integrates the three core needs of pets—toileting, eating, and exercising—into a single treadmill-shaped frame structure, achieving one-stop closed-loop care for pets' "eating, drinking, defecating, and moving." This eliminates the need for separate pet toilets, feeders, water dispensers, treadmills, and other equipment, greatly saving home space. It is especially suitable for pet-owning scenarios with limited space, such as urban apartments and small residences.

[0012] Furthermore, the cleaning system consists of an upward-opening door, a scraper, a flushing nozzle, and a drying air knife. The upward-opening door is rotatably connected to the upper shell. The scraper, flushing nozzle, and drying air knife are arranged sequentially along the traveling direction of the conveyor belt. The bottom shell is provided with a storage groove for storing waste, and the scraper and flushing nozzle are both located above the storage groove. The scraper is in close contact with the conveyor belt.

[0013] After the sensor system detects that a pet has defecated on the conveyor belt, cleaning is initiated within 60 seconds of the pet leaving the conveyor belt. The cleaning process is as follows: the conveyor belt is controlled to move the dirt on its surface upwards through a door, which opens and the dirt falls into the storage tank under its own gravity. A small amount of viscous dirt will still adhere to the surface of the conveyor belt. As the conveyor belt continues to run, the dirt is scraped off by a scraper. The conveyor belt then moves to the flushing nozzles, where water is sprayed onto the surface of the conveyor belt to clean it. Each cleaning uses approximately 0.3L of water. The conveyor belt then continues to run past the air dryer, where the air dryer removes the moisture from the surface of the conveyor belt until it returns to its initial position. This prevents the conveyor belt from becoming damp, which can breed bacteria and produce odors. The entire cleaning process is completed within 3 minutes.

[0014] Furthermore, the sensing system consists of an animal infrared sensor, a gravity sensor, an odor sensor, a liquid level sensor, a camera, and an operation panel. A sensor module is provided on the upper shell. The animal infrared sensor and the odor sensor are integrated into the sensor module. The sensor module and the camera are both located on the surface of the upper shell. The gravity sensor is located below the conveyor belt. The operation panel is located on the top of the upper shell. The liquid level sensor is located inside the storage system.

[0015] The animal infrared sensor is used to detect whether the pet is on the conveyor belt;

[0016] The gravity sensor is used to sense changes in weight on the transmission track and, in combination with the infrared sensor, serves as a cleaning operation start signal.

[0017] The odor sensor is used to monitor the concentration of gases such as ammonia and hydrogen sulfide in the surrounding area. When the concentration exceeds the set threshold, the deodorization system is activated.

[0018] The liquid level sensor is installed in the storage system to monitor the amount of cleaning liquid. When the amount is too low, an alert will be issued.

[0019] The camera is used to monitor the pet's condition and environment;

[0020] The operation panel is used for local parameter setting and control.

[0021] The sensing system supports three control modes: timed setting, automatic triggering, and remote control. It can activate functions such as cleaning, feeding, and exercise based on the pet's behavior or the owner's instructions.

[0022] Furthermore, the upper shell is provided with an exhaust vent, a water storage tank, and a food storage tank; the exhaust vent, water storage tank, and food storage tank together form a storage system, through which cleaning water is stored in the upper shell, and through which pet food is stored in the upper shell, and the liquid level sensor is installed in the water storage tank.

[0023] Furthermore, the interactive system consists of a display screen and a speaker. The display screen is located on the surface of the upper shell, and the speaker is located on the back of the display screen. According to the owner's preset time, guidance instructions are played periodically through the LCD screen and the speaker to attract the pet. When the conveyor belt also serves as a pet treadmill, the LCD screen can play animations or videos designed specifically for pets, which, together with the speaker, attract the pet to exercise on the conveyor belt, realizing the linkage between exercise and entertainment.

[0024] Furthermore, the bottom shell is provided with a water-retaining edge, and a guide plate is provided below the transmission track. The edges of the guide plate are connected to the bottom shell, and the guide plate is inclined towards the storage tank. When a pet urinates or drinks on the transmission track, the liquid remains on the transmission track and flows to both sides, falling into the gap between the transmission track and the bottom shell. Some liquid splashes and remains on the upper surface of the bottom shell. To address this issue, a water-retaining edge is added to the upper surface of the bottom shell, causing the liquid falling on the water-retaining edge to converge towards the center. This allows the liquid to flow from the gap between the transmission track and the bottom shell into the added guide plate. Similarly, the liquid flowing from the transmission track to both sides also flows onto the guide plate. The inclined guide plate then guides the liquid into the storage tank. In addition, when the flushing nozzles wash the transmission track, the splashed wastewater and the wastewater remaining and dripping from the transmission track are also guided into the storage tank through the guide plate, thereby achieving the collection of dirt and wastewater.

[0025] Furthermore, the cleaning system also includes a diaphragm pump, a sewage tank, and a sludge suction pipe. The suction port of the diaphragm pump is connected to the storage tank. The sewage tank is installed inside the bottom shell. The outlet of the diaphragm pump is connected to the sewage tank. The sludge suction pipe passes through the bottom shell and is connected to the sewage tank.

[0026] Sewage stored in the storage tank for a long time can also produce odors. Since the storage tank is connected to the outside, it is easy for odors to spread. Therefore, a diaphragm pump, a sewage tank, and a sludge suction pipe are added. After the sewage falls into the storage tank, the sewage generated by the flushing nozzles when rinsing the conveyor belt also flows into the storage tank. The sewage is diluted by the sewage. After the conveyor belt is cleaned, the diaphragm pump is started to pump the sewage and diluted sewage into the relatively sealed sewage tank. When the sewage tank is almost full, the sewage and sewage are pumped out through the sludge suction pipe.

[0027] Furthermore, the deodorization system consists of a ventilation grille and an exhaust vent. An exhaust vent is provided on the top of the upper shell, and a ventilation grille is provided on the side of the upper shell. The ventilation grille is connected to the exhaust vent, and deodorization consumables and an associated fan are placed inside the exhaust vent.

[0028] When the odor sensor detects that the concentration of gases such as ammonia and hydrogen sulfide in the surrounding area exceeds the set threshold, the fan of the deodorization system is activated, allowing the gas to enter the exhaust vent through the ventilation grille. After being filtered by the deodorizing consumables in the exhaust vent, the gas is discharged from the exhaust vent, thus achieving the deodorization operation. The deodorizing consumables are deodorizing filter elements, such as activated carbon, photocatalysis, or low-temperature plasma modules, which can be washed and reused without frequent replacement. The deodorization fan is automatically controlled to start and stop according to the odor sensor, and automatically stops deodorization 60 seconds after cleaning.

[0029] Furthermore, the feeding system consists of a food container, a feeding port, an electric slide rail, and a water dispenser. The ventilation grille is equipped with an electric slide rail, and the food container is connected to the moving part of the electric slide rail. The food container has a hollow structure without a bottom. The upper shell is equipped with a feeding port and a water dispenser. The feeding port is connected to the grain storage bin, and the water dispenser is connected to the water storage bin.

[0030] When the pet needs to be fed, the moving part of the electric slide rail moves down, causing the bottomless food container to cover the conveyor belt. Food is then dispensed in a measured amount through the feeding port for the pet to eat. When the pet stops eating and leaves the conveyor belt, the moving part of the electric slide rail is controlled to rise, causing the bottomless food container to move away from the conveyor belt, leaving food residue on the surface of the conveyor belt. Subsequently, the conveyor belt is cleaned synchronously, achieving automatic cleaning. The residue and wastewater are then discharged into the wastewater tank.

[0031] Furthermore, the bottom shell has a detachable ramp on its side, which facilitates entry and exit for pets of different sizes and is suitable for most pet types.

[0032] Furthermore, the transmission track has built-in cooling and heating functions to adapt to the usage needs of different seasons.

[0033] Furthermore, the scraper, flip-up door, water dispenser, lunch box, and conveyor belt are all detachable and made of corrosion-resistant materials for easy cleaning and replacement.

[0034] Furthermore, the water dispenser's terminal is freely rotatable to provide water for pets of different sizes.

[0035] Furthermore, the transmission track is made of green grass-patterned polymer track.

[0036] Furthermore, it also includes a mobile water replenishment and sewage pumping unit. The mobile water replenishment and sewage pumping unit is an independent component, shaped like a suitcase, and internally divided into a clean water chamber and a sewage chamber, which are equipped with a water pump and a sewage pump, respectively. It can be connected to the water storage tank and sewage tank of the main equipment through a quick-connect interface to realize the replenishment of clean water and the pumping out of sewage.

[0037] The beneficial effects of this invention are that it breaks through the technical limitations of existing pet care equipment, which has single functions and fragmented scenarios. It integrates the three core needs of pet dogs—toileting, eating, and exercising—into an integrated treadmill-shaped frame structure, realizing one-stop closed-loop care for pets' "eating, drinking, defecating, and moving." It eliminates the need for separate pet toilets, feeders, water dispensers, treadmills, and other equipment, greatly saving home space. Compared to placing four different devices separately, it saves more than 60% of space, making it especially suitable for pet-owning scenarios with limited space, such as urban apartments and small residences.

[0038] Meanwhile, the functional modules are divided into zones and work together to achieve space reuse. For example, the conveyor belt can also serve as a toilet carrier and a treadmill belt, which not only ensures the independence of each function but also avoids equipment redundancy and improves space utilization. The overall design of the equipment is simple and beautiful, and can be integrated into home decoration style without appearing abrupt.

[0039] Through conveyor belt transport, washing, drying and intelligent deodorization technology, cleaning is completed within 60 seconds after defecation, with significant odor control effect, and deodorization consumables can be washed and reused.

[0040] Adopting an integrated automatic cleaning process, the equipment can start cleaning within 60 seconds after pets defecate, and complete the cleaning process within 3 minutes, achieving no residue of dirt and no dampness on the conveyor belt; the scraper blade fits tightly with the conveyor belt, leaving no dead corners and scraping away sticky dirt; high-pressure washing and air knife drying prevent the conveyor belt from becoming damp, breeding bacteria and producing odors.

[0041] The deodorization system precisely removes odors, ensuring that the environment around the equipment is odor-free; the deodorization consumables are washable and reusable, eliminating the need for frequent replacements and solving the problems of high cost and environmental pollution associated with existing deodorization consumables.

[0042] All components of the equipment that come into contact with dirt and water, such as conveyor belts, lunch boxes, water dispensers, and sewage tanks, are made of corrosion-resistant materials and have a detachable design, which can further ensure thorough cleaning and prevent the growth of odors.

[0043] Equipped with a multi-sensor collaborative sensing system, including infrared sensors, gravity sensors, odor sensors, and liquid level sensors, it can accurately sense pets' toileting, eating, and exercise behaviors, enabling the device to automatically trigger operation without manual intervention. It supports three control modes: timed setting, automatic triggering, and remote control, adapting to different pet-owning scenarios. When pets are alone at home, it can automatically complete feeding, watering, defecation cleaning, deodorization, and exercise guidance, greatly reducing the care burden on owners.

[0044] Equipped with wireless communication capabilities, users can remotely view pet activity and device status via a mobile app, manually control the device, and receive device alerts, enabling them to manage pet care anytime, anywhere. Detachable ramps, mobile water replenishment and sewage pumping units, and other auxiliary modules further enhance ease of use, adapting to pets of different sizes and different pet-keeping scenarios, and solving the problem of inconvenient water replenishment and sewage discharge in high-rise apartments.

[0045] Each cleaning uses 0.3L of water, precisely controlling water consumption; deodorizing consumables are washable and reusable, reducing long-term usage costs and environmental burden; tracks can be equipped with cooling and heating functions to adapt to different seasonal usage needs; tracks, feeding boxes, and other components are detachable and washable, reducing maintenance costs.

[0056] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0057] See Figure 1-4 This embodiment provides a multifunctional self-cleaning and odorless pet dog toilet, including:

[0058] The bottom shell 1 contains a transmission track 5 and a cleaning system. The transmission track 5 is used to provide a standing platform for the pet, and the cleaning system is used to clean the dirt on the surface of the transmission track 5.

[0059] The upper shell 2 is located above the bottom shell 1 and is detachably connected to the bottom shell 1. The upper shell 2 is equipped with a sensing system, a feeding system, an interactive system, a deodorizing system, and a storage system. The sensing system is used to identify the pet's status, the feeding system is used to feed the pet, the interactive system is used to interact with the pet and play guidance commands, the deodorizing system is used to ensure that there are no odors in the surrounding environment of the device, and the storage system is used to store the corresponding consumables.

[0060] This invention enables pets to function as treadmills by controlling the operation of the transmission belt 5 when they need to exercise. The invention also uses a sensing system to identify the pet's status and operate in different modes. Furthermore, the invention allows for remote communication with the pet or issuing commands such as eating, running, and toileting through an interactive system. When there is dirt on the surface of the transmission belt 5, the invention cleans the surface of the transmission belt 5 using a cleaning system.

[0061] By incorporating sensing and feeding systems into the bottom shell 1 and top shell 2, this technology overcomes the limitations of existing pet care equipment, which suffers from single-function design and fragmented usage scenarios. It integrates the three core needs of pets—toileting, eating, and exercising—into a single treadmill-shaped frame structure, achieving one-stop closed-loop care for pets' "eating, drinking, defecating, and moving." This eliminates the need for separate pet toilets, feeders, water dispensers, treadmills, and other equipment, greatly saving home space. It is especially suitable for pet-owning scenarios with limited space, such as urban apartments and small residences.

[0062] In this embodiment, the cleaning system consists of an upper door 6, a scraper 61, a flushing nozzle 62, and a drying air knife 63. The upper door 6 is rotatably connected to the upper shell 2. The scraper 61, the flushing nozzle 62, and the drying air knife 63 are arranged sequentially along the traveling direction of the conveyor belt 5. The bottom shell 1 is provided with a storage groove 14 for storing waste, and the scraper 61 and the flushing nozzle 62 are both located above the storage groove 14. The scraper 61 is in close contact with the conveyor belt 5.

[0063] After the sensor system detects that a pet has defecated on the conveyor belt 5, cleaning is initiated within 60 seconds after the pet leaves the conveyor belt 5. The specific cleaning process is as follows: the conveyor belt 5 is controlled to move, causing the dirt on its surface to move upward to the lifting door 6, opening the lifting door 6. The dirt on the surface of the conveyor belt 5 falls into the storage tank 14 under its own gravity. A small amount of sticky dirt will still adhere to the surface of the conveyor belt 5. As the conveyor belt 5 continues to move, the dirt is scraped off by the scraper 61. Then the conveyor belt 5 moves to the flushing nozzle 62, where water is sprayed onto the surface of the conveyor belt 5 for cleaning. Each cleaning uses about 0.3L of water. Then the conveyor belt 5 continues to move past the drying air knife 63, where the drying air knife 63 removes the moisture from the surface of the conveyor belt 5 until the conveyor belt 5 returns to its initial position, preventing the conveyor belt 5 from becoming damp and breeding bacteria and producing odors. The entire cleaning process is completed within 3 minutes.

[0064] In this embodiment, the sensing system consists of an animal infrared sensor, a gravity sensor, an odor sensor, a liquid level sensor, a camera 41, and an operation panel 24. A sensor module 73 is provided on the upper shell 2. The animal infrared sensor and the odor sensor are integrated in the sensor module 73. The sensor module 73 and the camera 41 are both located on the surface of the upper shell 2. The gravity sensor is located below the conveyor belt 5. The operation panel 24 is located on the top of the upper shell 2. The liquid level sensor is located in the storage system.

[0065] An animal infrared sensor is used to detect whether a pet is on the conveyor belt 5;

[0066] A gravity sensor is used to detect weight changes on the transmission track 5, and it is combined with an infrared sensor as a cleaning operation start signal.

[0067] Odor sensors are used to monitor the concentration of gases such as ammonia and hydrogen sulfide in the surrounding environment. When the concentration exceeds the set threshold, the deodorization system is activated.

[0068] A liquid level sensor is installed in the storage system to monitor the amount of cleaning liquid. When the level is too low, an alert will be issued.

[0069] Camera 41 is used to monitor the pet's condition and environment;

[0070] The operation panel 24 is used for local parameter setting and control.

[0071] The sensing system supports three control modes: timed setting, automatic triggering, and remote control. It can activate functions such as cleaning, feeding, and exercise based on the pet's behavior or the owner's instructions.

[0072] In this embodiment, an exhaust vent 21, a water storage tank 22, and a food storage tank 23 are provided on the upper shell 2. The exhaust vent 21, the water storage tank 22, and the food storage tank 23 together form a storage system. The water storage tank 22 stores cleaning water into the upper shell 2, and the food storage tank 23 stores pet food into the upper shell 2. A liquid level sensor is installed in the water storage tank 22.

[0073] In this embodiment, the interactive system consists of a display screen 4 and a speaker 42. The display screen 4 is located on the surface of the upper shell 2, and the speaker 42 is located on the back of the display screen 4. According to the owner's preset time, guidance instructions are played periodically through the LCD screen and the speaker 42 to attract the pet. When the conveyor belt 5 also serves as a pet treadmill, the LCD screen can play animations or videos designed specifically for pets, which, together with the speaker 42, attract the pet to exercise on the belt, realizing the linkage between exercise and entertainment.

[0074] In this embodiment, the bottom shell 1 is provided with a water-retaining edge 13, and a guide plate 11 is provided below the transmission track 5. The edges of the guide plate 11 are all connected to the bottom shell 1, and the guide plate 11 is inclined towards the storage groove 14. When a pet urinates or drinks on the transmission track 5, the liquid remains on the transmission track 5 and flows to both sides, falling into the gap between the transmission track 5 and the bottom shell 1. Some of the liquid will splash and remain on the upper surface of the bottom shell 1. To address this problem, a water-retaining edge 13 is added to the upper surface of the bottom shell 1, so that the liquid falling on the water-retaining edge 13 is contained within the water-retaining edge 13. The liquid converges towards the center, allowing it to flow from the gap between the conveyor belt 5 and the bottom shell 1 into the added guide plate 11. Similarly, the liquid flowing from the conveyor belt 5 to both sides also flows onto the guide plate 11. The guide plate 11 is then tilted to guide the liquid into the storage tank 14. In addition, when the flushing nozzle 62 washes the conveyor belt 5, the splashed sewage and the sewage remaining and dripping on the conveyor belt 5 are also guided into the storage tank 14 through the guide plate 11, thereby achieving the convergence of dirt and sewage.

[0075] In this embodiment, the cleaning system also includes a diaphragm pump 64, a sewage tank 65, and a sludge suction pipe 66. The suction port of the diaphragm pump 64 is connected to the storage tank 14. The sewage tank 65 is provided inside the bottom shell 1. The outlet of the diaphragm pump 64 is connected to the sewage tank 65. The sludge suction pipe 66 passes through the bottom shell 1 and is connected to the sewage tank 65.

[0076] Sewage stored in storage tank 14 for a long time will also produce odors. Since storage tank 14 is connected to the outside, it is easy for odors to spread. Therefore, a diaphragm pump 64, a sewage tank 65 and a sewage suction pipe 66 are added. After the sewage falls into storage tank 14, when the flushing nozzle 62 washes the conveyor belt 5, the sewage generated by the flushing also flows into storage tank 14. The sewage is diluted by the sewage. After the conveyor belt 5 is cleaned, the diaphragm pump 64 is started. The sewage and diluted sewage are pumped into the relatively sealed sewage tank 65 by the diaphragm pump 64. When the sewage tank 65 is almost full, the sewage and sewage are pumped out through the sewage suction pipe 66.

[0077] In this embodiment, the deodorization system consists of a ventilation grille 3 and an exhaust vent 21. An exhaust vent 21 is provided on the top of the upper shell 2, and a ventilation grille 3 is provided on the side of the upper shell 2. The ventilation grille 3 is connected to the exhaust vent 21, and deodorization consumables and associated fans are placed inside the exhaust vent 21.

[0078] When the odor sensor detects that the concentration of gases such as ammonia and hydrogen sulfide in the surrounding area exceeds the set threshold, the fan of the deodorization system is activated, allowing the gas to enter the exhaust port 21 through the ventilation grille 3. After being filtered by the deodorization consumables in the exhaust port 21, the gas is discharged from the exhaust port 21, thus achieving the deodorization operation. The deodorization consumables are deodorization filter elements, such as activated carbon, photocatalysis, or low-temperature plasma modules, which can be washed and reused without frequent replacement. The deodorization fan is automatically controlled to start and stop according to the odor sensor, and automatically stops deodorization 60 seconds after cleaning.

[0079] In this embodiment, the feeding system consists of a food box 7, a feeding port 71, an electric slide rail 72, and a water dispenser 74. The ventilation grille 3 is equipped with an electric slide rail 72, and the food box 7 is connected to the moving part of the electric slide rail 72. The food box 7 has a hollow structure without a bottom. The upper shell 2 is equipped with a feeding port 71 and a water dispenser 74. The feeding port 71 is connected to the grain storage bin 23, and the water dispenser 74 is connected to the water storage bin 22.

[0080] When the pet needs to be fed, the moving part of the electric slide rail 72 moves down, causing the bottomless food container 7 to cover the conveyor belt 5. Then, food is dispensed in a measured amount through the feeding port 71 for the pet to eat. When the pet stops eating and leaves the conveyor belt 5, the moving part of the electric slide rail 72 is raised, causing the bottomless food container 7 to move away from the conveyor belt 5, so that food residue remains on the surface of the conveyor belt 5. Subsequently, the conveyor belt 5 is cleaned synchronously, realizing automatic cleaning. The residue and wastewater are then discharged into the wastewater tank 65.

[0081] In this embodiment, the bottom shell 1 is detachably connected to a ramp 12 on the side, which facilitates the entry and exit of pets of different sizes and is suitable for most types of pets.

[0082] In this embodiment, the transmission track 5 has built-in cooling and heating functions to adapt to the usage needs of different seasons.

[0083] In this embodiment, the scraper 61, the flip-up door 6, the water dispenser 74, the lunch box 7, and the conveyor belt 5 are all detachable and made of corrosion-resistant materials to facilitate cleaning and replacement.

[0084] In this embodiment, the end of the water dispenser 74 can be freely rotated to provide water for pets of different sizes.

[0085] In this embodiment, the transmission track 5 is a green lawn-patterned polymer track.

[0086] This embodiment also includes a mobile water replenishment and sewage pumping unit. The mobile water replenishment and sewage pumping unit is an independent component, resembling a suitcase in shape. It is internally divided into a clean water chamber and a sewage chamber, which are equipped with a water pump and a sewage pump, respectively. It can be connected to the water storage tank 22 and sewage tank 65 of the main equipment through a quick-connect interface to realize the replenishment of clean water and the pumping out of sewage.
