Description

Technical Field

[0001] This application relates to the field of pet product manufacturing technology, and in particular to a pet toilet and its usage method. Background Technology

[0002] Currently, my country's pet industry is developing rapidly, with pet cats and dogs becoming increasingly popular among busy young urban workers, leading to explosive growth in related industries in recent years.

[0003] Existing pet toilets, such as cat litter boxes, typically place absorbent cat litter or other clumps inside the container. After the pet's urine and feces clump together, they are removed manually or mechanically and left aside. There is no mechanism for treating the waste or cleaning the container, making it impossible to clean the pet toilet and treat the waste in a timely manner. This results in the pet toilet not being cleaned for a long time, and the waste being left for extended periods can easily breed bacteria and produce odors. Furthermore, the need for manual waste disposal can cause discomfort and even affect human health.

[0004] The Chinese patent application filed by the applicant, with application number CN202411262584.X and titled "Pet Urine and Feces Device and Method of Use Thereof," effectively solves the above-mentioned problems.

[0106] The following is combined Figures 1 to 14 The specific structure of this application will be further elaborated.

[0107] refer to Figures 1 to 14 In this embodiment, the pet toilet is preferably a water-washable cat toilet suitable for pet cats. The pet toilet includes a base, which includes a modular, detachable base module 1, a water-washing tank module 2, and a control host 3. In this application, all electrical components, such as circuits and electrical parts, are housed within the control host. This application can be used with or without the extended litter box 4: When the extended litter box is combined, it is detachably mounted on top of the base module, and the water-washing tank module and the control host are detachably placed on the extended litter box, with the water-washing tank module and the control host being detachably connected; when the extended litter box is not combined, the water-washing tank module and the control host are detachably mounted on the base module, with the water-washing tank module and the control host being detachably connected.

[0108] Specifically, when the extended litter box is used, the extended litter box is detachably positioned above the base module, and the water washing box module and the control host are detachably positioned above the extended litter box. The second cat litter transfer channel transfers the cat litter cleaned by the water washing mechanism to the extended litter box.

[0109] When the extended litter box is not in use, the water washing box module and the control host are detachably positioned above the base module, and the second litter transfer channel transfers the litter cleaned by the water washing mechanism to the litter container.

[0110] The base module includes a base 11, a litter container 12, a litter container cover 13, and two side panels 14 located on both sides of the top of the litter container cover. The base and the litter container cover are fastened together. The litter container is rotatably mounted on the base module of the base, specifically between the base and the litter container cover. A notch 15 is formed between the front ends of the two side panels, allowing the cat to enter.

[0111] The cat litter container is designed as a round basin with a larger diameter at the top and a smaller diameter at the bottom. It contains washable cat litter. The inner wall of the cat litter container is a concave bottom wall at the center, preferably an arc-shaped bottom or a conical bottom. A cat litter outlet 16 is provided at the center of the bottom of the cat litter container to facilitate the discharge of cat litter mixed with cat feces after the cat defecates. Preferably, the central axis of the cat litter container's rotation passes through the center of the cat litter outlet.

[0112] The base is provided with a cat litter container rotation drive mechanism that drives the cat litter container to rotate. Specifically, the upper edge of the cat litter container is provided with a toothed ring 121. The cat litter container rotation drive mechanism includes a gear 122 that drives and cooperates with the toothed ring. In this embodiment, it is preferred that the toothed ring and the gear are directly meshed.

[0113] The control unit contains a litter container rotation drive motor 31 that drives the gear to rotate, and the output end of the litter container rotation drive motor is equipped with the gear. When the extended litter box is used in combination, the gear is driven through the docking drive shaft 123, the docking gear, and the gear ring inside the extended litter box; when the extended litter box is not used in combination, the gear is directly driven through the gear ring.

[0114] The base is equipped with a first litter transfer channel 17 that is connected to the litter outlet. After the cat defecates, the litter mixed with cat feces is discharged through the litter outlet and enters the first litter transfer channel.

[0115] The base is also equipped with a litter outlet opening and closing device to control the opening or closing of the litter outlet. When the litter outlet is open, the litter in the litter container can enter the first litter transfer channel.

[0116] In this embodiment, the cat litter outlet opening and closing device includes a cat litter outlet baffle 18 that can be translatably disposed and a cat litter outlet baffle driving mechanism that drives the cat litter outlet baffle to move at least between a first position and a second position. When the cat litter outlet baffle driving mechanism drives the cat litter outlet baffle to move to the first position, the cat litter outlet opens. When the cat litter outlet baffle driving mechanism drives the cat litter outlet baffle to move to the second position, the cat litter outlet closes.

[0117] Preferably, the cat litter outlet baffle is provided with a urine leakage hole 181. When the cat litter outlet baffle driving mechanism drives the cat litter outlet baffle to the second position, that is, when the cat litter outlet is in the closed state, the urine leakage hole is correspondingly set with the cat litter outlet. The size of the urine leakage hole is only enough to allow the cat's urine to pass through but not the cat litter. That is, when the cat only urinates in the cat litter container, the urine is drained through the urine leakage hole or further processed to keep the cat litter container relatively dry.

[0118] The litter outlet baffle drive mechanism includes a litter outlet baffle drive motor 32 housed in the control unit and a litter outlet baffle drive gear 182 mounted on the base. The output end of the litter outlet baffle drive motor is connected to the litter outlet baffle drive gear. The litter outlet baffle is equipped with a rack 183 that engages with the litter outlet baffle drive gear. Since the base, control unit, and extended litter box module are independent modular structures in this embodiment, an output docking part 321 is provided at the output end of the litter outlet baffle drive motor 32, a baffle gear mounting shaft 184 is connected to the litter outlet baffle drive gear, and an input docking part 185 is provided at the upper end of the baffle gear mounting shaft. When the extended litter box is used in combination, the output docking part is connected and driven through the docking transmission shaft inside the extended litter box and the input docking part of the baffle gear mounting shaft; when the extended litter box is not used in combination, the output docking part is directly connected and driven through the input docking part of the baffle gear mounting shaft.

[0119] In this application, the cat litter in the litter container enters the first litter transfer channel through the litter outlet by gravity and / or the impact of water flow. In this embodiment, a flushing mechanism is used to flush water into the litter container, thereby flushing the cat feces and litter in the litter container into the first litter transfer channel. This flushing mechanism can be a water inlet pipe connected to a tap water pipe, or a water tank configured on a base. The specific form of the flushing mechanism is not limited here, as long as it can provide water flow.

[0120] The grinding mechanism 191, the cat feces and cat litter separation mechanism, and the cat litter transfer mechanism 192 are arranged sequentially along the extension direction of the first cat litter transfer channel. In this embodiment, a cat feces and cat litter inlet 1911 is provided on the front side of the outer shell of the grinding mechanism, and a filter hole 1912 is provided on the rear side, which allows cat litter to pass through but prevents large pieces of cat feces from passing through, forming the aforementioned cat feces and cat litter separation mechanism. The cat litter transfer mechanism forms a cat litter inlet 1921 corresponding to the filter hole. After the cat litter mixed with cat feces is flushed into the first cat litter transfer channel by water, it enters the grinding mechanism through the cat feces and cat litter inlet. At this time, large pieces of cat feces are trapped in the grinding mechanism, and the cat litter and water pass through the filter hole and enter the cat litter transfer mechanism. The cat litter and water that enter the cat litter transfer mechanism are pumped to the cat litter washing mechanism for cleaning by the cat litter transfer mechanism. Then, the grinding mechanism is started to crush the trapped cat feces and discharge it, preferably into the sewer.

[0121] The grinding mechanism is a conventional grinding mechanism, generally employing a grinding motor 36 driving a grinding disc to rotate. Alternatively, the grinding mechanism in the applicant's Chinese patent application CN202411262584.X is existing technology and will not be elaborated upon here. In this embodiment, the grinding motor is housed within the control unit. The output end of the grinding motor has a grinding motor output docking part 361. When the extended sand box is used in combination, this grinding motor output docking part is connected and driven through the corresponding docking transmission shaft within the extended sand box and the input docking part of the baffle gear mounting shaft. When the extended sand box is not used in combination, this grinding motor output docking part is directly connected and driven through the input docking part of the grinding disc mounting shaft.

[0122] The litter transfer mechanism can employ a pumping structure, such as a centrifugal pump or a mud pump, or a conveying spiral structure; these are conventional technologies that simply lift the litter or litter and water to the litter washing mechanism, and will not be elaborated upon here. In this embodiment, a litter transfer drive motor 37 is installed in the control host. The output end of the litter transfer drive motor is provided with a litter transfer output docking part 371. When an extended litter box is used in conjunction with the motor, the output docking part of the litter transfer drive motor is connected and driven through the corresponding docking transmission shaft inside the extended litter box and the input docking part of the pumping structure. When the extended litter box is not used in conjunction with the motor, the output docking part of the grinding motor is directly connected and driven through the input docking part of the pumping structure.

[0123] The cat litter washing mechanism includes a washing tank 21 consisting of an upper shell and a lower shell, and a rotatable rotating cylinder 22 disposed inside the washing tank. The rotating cylinder is provided with a water permeable hole 221. The washing tank is provided with a spray component 23 for spraying water onto the rotating cylinder. The rotating cylinder is provided with a litter inlet 222 and a litter outlet 223. The cat litter transfer mechanism is connected to the litter inlet. The inner wall of the rotating cylinder is provided with a conveying spiral 224. When the rotating cylinder rotates in one direction, it is used to wash the cat litter. When the rotating cylinder rotates in the opposite direction, it is used to convey the cat litter to the litter outlet. The working principle is similar to that of the mixing drum of a cement mixer.

[0124] The rotating drum is provided with a rotating shaft 225 at both ends and between the rotating drum and the washing tank for rotatable connection between the two; at least one rotating shaft is provided with a litter inlet channel, or at least one rotating shaft is provided with an air inlet channel 2251 for drying or baking the cat litter in the rotating drum by air intake; or at least one rotating shaft is provided with a litter outlet for outputting the cat litter in the rotating drum; or at least one rotating shaft and the rotating drum are provided with the litter outlet for conveying the cat litter in the rotating drum out.

[0125] In this embodiment, a sand inlet channel is provided in the rotating shaft on one side, and the outer end of the sand inlet channel forms the sand inlet. An air inlet channel is provided in the rotating shaft on the other side, and a sand outlet is provided between the rotating shaft and the rotating cylinder. A second cat litter transfer channel 226 is also provided below the sand outlet, which is used to transfer the cat litter that has been washed by the cat litter washing mechanism and dried by the air drying mechanism to the cat litter container or the extended litter box.

[0126] The washing tank is equipped with a drain hole 227 and an overflow hole 228. The drain hole is positioned lower than the overflow hole. When the cat litter washing mechanism washes the cat litter, the water flowing out of the overflow hole from the washing tank can flow through the water channel to the cat litter container to rinse it, which can save water. Since the overflow hole is positioned higher, it can prevent the water in the washing tank from running out.

[0127] The control host is equipped with a rotating drum rotation drive mechanism for driving the rotating drum to rotate. Specifically, it includes a rotating drum rotation drive motor 34 and a rotating drum rotation drive gear 341 that is in transmission cooperation with the rotating drum rotation drive motor. The rotating shaft of the rotating drum is equipped with a transmission gear 229 that cooperates with the rotating drum rotation drive gear.

[0128] The control unit also includes a drying mechanism for supplying air to the litter container to dry it and / or to the washing mechanism to dry the litter container and litter. Preferably, the drying mechanism supplies hot air to the litter container and / or the washing mechanism. Specifically, a fan 35 is installed in the control unit, and an electric heating structure is configured behind the fan so that the air blown out by the fan is hot air. This is existing technology and will not be described in detail here. The fan's air outlet 351 is connected to the air inlet channel.

[0129] refer to Figures 15 to 17 The extended litter box includes a box body composed of an upper shell 41 and a lower shell 42. A litter storage space 43 is provided inside the box body between the upper shell and the lower shell. A litter outlet channel 44 is provided at the bottom of the box body for docking and communicating with the litter container. A litter inlet channel 45 is provided at the top of the box body for docking and communicating with the litter outlet of the litter washing mechanism. The box body is provided with a litter outlet control mechanism for opening or closing the litter outlet channel. A vibration motor 46 is provided on the box body for vibrating and dropping the litter from the litter storage space into the litter storage space and the litter outlet channel.

[0130] The upper shell is provided with an inclined flow guide surface 411, the sand inlet channel is located at the upper end of the flow guide surface, and the upper shell is provided with a baffle plate 412 at the lower end of the flow guide surface. A flow guide hole 413 connecting the cat litter storage space is provided between the baffle plate and the flow guide surface, and the baffle plate is provided with multiple partitions 414.

[0131] The sand discharge control mechanism includes a sand discharge baffle 47 blocking the sand discharge channel and a sand discharge control motor 48 that controls the movement of the sand discharge baffle.

[0132] The housing is equipped with a docking transmission component for docking the functional mechanism on the base module and the power component in the control host. In this embodiment, the functional mechanism is specifically the mechanical transmission part of the grinding mechanism, the litter transfer mechanism, and the litter outlet opening and closing device. The power component in the control host is mainly the motor part of the grinding mechanism, the litter transfer mechanism, and the litter outlet opening and closing device. The docking transmission component is the docking transmission shaft, which has been described in detail above and will not be repeated here.

[0133] The drive shafts of the grinding mechanism and litter transfer mechanism are prone to cat hair entanglement, requiring manual cleaning and thus routine maintenance. This application also includes an anti-tangling device installed in the housing of the extended litter box to prevent cat hair from tangling on the shaft. The anti-tangling device includes a cat hair removal agent bottle 491 located inside the housing of the extended litter box and a pump assembly 492 for pumping the cat hair removal agent from the bottle into the drive shaft of the litter transfer mechanism and / or grinding mechanism. The cat hair removal agent corrodes the cat hair at the shaft, making it brittle and prone to breakage. By adding a cat hair removal mechanism, the routine maintenance cycle of the equipment can be extended, or maintenance can be eliminated altogether.

[0134] This pet toilet application can easily achieve pet cat litter cleaning. The control circuit is set in the control host, which can realize automatic processing, automatic cleaning and automatic drying of cat litter. It has a high degree of intelligence. The power supply, circuit and electrical components are set in the control host, and water and electricity are separated. The base and water washing tank module have no electrical components at all. The extended litter box is equipped with a docking drive shaft to realize the transmission of power and signals.

[0135] This application separates cat feces from cat litter in a mixed state of water, sand, and feces, and uses the principle of a mud pump to transfer the cat litter. At the same time, because the separation occurs inside the machine, odor control is more effective. This separation method completely eliminates movable shovels and other cleaning components, making it safer for cats and providing a more comfortable space to use.

[0136] In this application, cat litter is washed and dried in an independent space, without occupying the cat litter container (the space used by the cat). The litter is tumbled, making the washing process cleaner and more efficient. The washing is more effective, more water-saving, and more environmentally friendly. Compared with existing designs, it saves more than 50% of water. The independent drying space greatly improves the utilization rate of hot air and makes drying faster.

[0137] This application provides spare cat litter by extending the litter box, greatly facilitating use in multi-cat households; with this design, multi-cat households can add the use of the extended litter box, giving users more options.

[0138] This application features no exposed cables or plugs; the control unit and expansion sandbox are connected via gold fingers, resulting in an aesthetically pleasing design. It can utilize a camera in conjunction with AI calculations to determine cat excretion behavior and identify multiple cats.

[0139] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
