Description

Technical Field

[0001] This invention relates to the field of pet supplies technology, and more particularly to a pet toilet. Background Technology

[0002] With social progress and improved living standards, more and more pets are entering people's homes. Currently, cats and dogs are generally kept indoors in urban households, and are trained to defecate in designated areas. To facilitate pet elimination, pet toilets are usually placed indoors. However, in this technology, pet toilets are only for pets to eliminate, requiring users to manually clean the waste. If users do not clean the waste promptly, it will remain exposed to the indoor environment for a long time, polluting indoor air and reducing indoor air quality. Furthermore, the accumulation of solid and liquid waste in the pet toilet not only intensifies odor spread and breeds large amounts of bacteria, further affecting indoor air quality and harming pet health, but also makes cleaning more difficult for users as the mixture adheres to the inner walls and crevices of the toilet.

[0053] The technical solution provided by this invention has at least the following advantages:

[0054] The pet toilet provided by this invention includes a base, a surrounding panel, a waste container, a waste collection container, and a transfer assembly. The base has a designated area for the pet to defecate, and the surrounding panel defines the defecation area. This confines the pet to the designated area for defecation, achieving targeted defecation. The base is hollow and contains the waste container and waste collection container. Multiple drainage holes are provided on the waste container. A transfer assembly with a movable transfer section is also provided within the base. The waste container serves two purposes: it supports the pet, facilitating defecation; it also isolates the pet from the transfer section, ensuring the pet's safety and preventing damage to the transfer section from large pets. After the pet defecates on the waste container, the excrement falls through the drainage holes onto the transfer section within the base and is then transferred to the waste container and / or the waste collection container. This system not only effectively isolates pets and excrement, preventing pets from ingesting or becoming soiled with them, but also allows for timely and centralized disposal of excrement, preventing its exposure to the indoor environment, improving indoor air quality, and ensuring pet health. After being transferred by the transfer unit, the litter box collects at least a portion of the pet's solid excrement, while the waste collection box collects at least a portion of its liquid excrement. This allows for solid-liquid separation during collection; the liquid excrement entering the waste collection box can be quickly sealed or diverted, reducing the diffusion of ammonia gas produced by the decomposition of liquid excrement. After solid-liquid separation, the dry solid excrement is less conducive to bacterial growth, and the separate storage of liquid excrement reduces cross-contamination. Furthermore, the dry solid excrement in the litter box can be directly picked up and cleaned, and the liquid excrement in the waste collection box can be discharged separately, eliminating the need for users to handle viscous mixtures and reducing the difficulty of cleaning the pet toilet.

[0068] With social progress and improved living standards, more and more pets are entering people's homes. Currently, cats and dogs are generally kept indoors in urban households, and are trained to defecate in designated areas. Pet toilets are also provided for pets to relieve themselves.

[0069] To facilitate the timely disposal of pet excrement, this invention improves the structure of the pet toilet 100. The structure of the pet toilet 100 will be described in detail below with reference to the accompanying drawings.

[0070] Please see Figures 1 to 3 The pet toilet 100 includes a base 1, a partition 2, a waste container 31, a waste collection container 32, and a transfer assembly 33. The base 1 has a litter box 11 for holding the pet, and the litter box 11 is surrounded by the partition 2 to define a litter area a; in this way, the pet is confined to the litter area a on the litter box 11 to defecate, thereby achieving the pet's fixed-point defecation.

[0071] In addition, the base 1 is hollow and contains a litter box 31 and a waste collection box 32. Multiple drainage holes 121 are provided on the litter box 11. A transfer assembly 33 is also provided inside the base 1, and the transfer assembly 33 has a movable transfer part 331. The litter box 11 serves two purposes: firstly, it can support the pet, facilitating its defecation; secondly, it isolates the pet from the transfer part 331, ensuring the pet's safety and preventing the transfer part 331 from being damaged by large pets.

[0072] After a pet defecates on the litter box 11, the excrement falls through multiple drain holes 121 onto the transfer section 331 inside the base 1, and is then transferred to the waste container 31, or the waste collection container 32, or both. This not only effectively isolates the pet from the excrement, preventing the pet from ingesting it or getting it on its body, but also allows for timely collection and disposal of the excrement, preventing it from being exposed to the indoor environment, improving indoor environmental quality, and ensuring the pet's health.

[0073] Understandably, pet excrement typically consists of both solid and liquid components. After being transferred by the transfer unit 331, the waste bin 31 collects at least a portion of the pet's solid excrement, while the waste collection bin 32 collects at least a portion of the pet's liquid excrement. This allows for solid-liquid separation during waste collection, enabling the liquid excrement entering the waste collection bin 32 to be quickly sealed or diverted, thereby reducing the diffusion of ammonia gas generated from the decomposition of the liquid excrement. Furthermore, after solid-liquid separation, the dried solid excrement is less conducive to bacterial growth, and the separate storage of the liquid excrement reduces cross-contamination of microorganisms. Additionally, the dried solid excrement in the waste bin 31 can be directly picked up and cleaned, and the liquid excrement in the waste collection bin 32 can be discharged separately, eliminating the need for users to handle viscous mixtures and reducing the difficulty of cleaning the pet toilet.

[0074] After the pet finishes defecating on the litter box 11, the excrement falls through multiple drain holes 121, and some of it remains on the litter box 11. In order to keep the pet toilet 100 clean, the litter box 11 needs to be cleaned.

[0075] In one embodiment, please refer to Figure 2 The base 1 has an opening 14 at its top that connects to its interior. The pet toilet 100 also includes a support plate 16, which is detachably installed at the opening 14 to form a litter box 11. Multiple drain holes 121 are provided on the support plate 16. After the pet has finished defecating, if the user finds excrement residue on the support plate 16, the user can remove the support plate 16 for cleaning, thus facilitating the pet's next defecation.

[0076] Furthermore, when a pet defecates on the litter box 11, the point of defecation within the defecation area a is uncertain. To ensure complete collection of excrement, the vertical projection of the litter box 11 at least partially overlaps with the first opening 311 of the waste bin 31, and some of the multiple drain holes 121 on it are corresponding to the first opening 311. In other words, the litter box 11 not only covers the transfer component 33 but also extends to the opening of the waste bin 31, and some of its drain holes 121 are also corresponding to the opening of the waste bin 31. Thus, even if the pet does not defecate aligned with the transfer component 33, its excrement will fall directly into the waste bin 31 through the drain holes 121.

[0077] The present invention does not impose specific limitations on the form of the transfer component 33. The transfer component 33 can be configured as a flexible transmission component. Taking the transfer component 33 as a conveyor belt assembly as an example, the conveyor belt of the conveyor belt assembly serves as the transfer part 331 for transferring excrement. The transfer component 33 has an upstream end b and a downstream end c in its transfer direction.

[0078] In one embodiment, please refer to Figure 2 and Figure 3 Both the sludge chamber 31 and the sludge collection chamber 32 are located at the downstream end c, so that when the transfer unit 331 transfers the excrement from the upstream end b to the downstream end c, the excrement on it can enter the sludge chamber 31 and / or the sludge collection chamber 32.

[0079] As mentioned above, pet excrement is usually in a solid and liquid state; however, when a pet has diarrhea, its excrement may be a mixture of solid and liquid. Taking conveyor belt transfer as an example, a feces chamber 31 and a waste collection chamber 32 are simultaneously provided at the downstream end c of the transfer component 33; when the conveyor belt transfers solid excrement, the excrement will fall into the feces chamber 31 at the downstream end c in a parabolic trajectory due to the inertia of the conveyor belt.

[0080] When the conveyor belt transports solid-liquid mixed excrement, some solid excrement will be sent to the septic tank 31; however, because the conveyor belt moves at a relatively slow speed, some liquid excrement cannot be delivered to the septic tank 31. When the conveyor belt passes the corner at the downstream end c, it will flow down naturally due to gravity and be received by the sludge collection tank 32.

[0081] When the conveyor belt transports liquid excrement, some of it is sent to the waste bin 31; while the remaining liquid excrement on the conveyor belt flows down naturally due to gravity as it passes the corner at the downstream end c, and is collected by the waste collection bin 32. Thus, through the combined action of the waste bin 31 and the waste collection bin 32, the excrement can be completely collected, thereby improving the cleaning effect of the pet toilet 100.

[0082] In other words, the transfer unit 331 can transfer at least a portion of the solid excrement to the toilet 31; it can also transfer at least a portion of the liquid excrement to the sludge collection 32; or it can transfer the excrement to both the toilet 31 and the sludge collection 32 at the same time.

[0083] To ensure that excrement falls accurately into the waste collection chamber 31, in one embodiment, the first opening 311 of the waste collection chamber 31 is at least partially upward, and the upward-facing area is at least partially lower than the top of the downstream end c. The bottom of the waste collection chamber 31 is at least partially higher than the sludge collection chamber 32.

[0084] The first compartment opening 311 is partially upward-facing, allowing it to directly receive excrement falling from the downstream end c, preventing it from deviating from its course or falling outside the latrine 31 due to inertia. The upward-facing area of ​​the first compartment opening 311 is at least partially lower than the top of the downstream end c, creating a natural height difference between the downstream end c and the first compartment opening 311. After the excrement travels to the downstream end c with the transfer unit 331, it slides into the latrine 31 along this height difference, requiring no additional power.

[0085] As mentioned above, when the excrement is a solid-liquid mixture or liquid, some of the liquid excrement may not be able to enter the toilet bowl 31 and instead enters the sludge collection chamber 32 due to gravity. Understandably, a drain outlet 621 or a drain pipe is usually installed to drain and clean the sewage in the sludge collection chamber 32.

[0086] The bottom of the toilet chamber 31 is at least partially higher than the sludge collection chamber 32. When the excrement is transferred to the downstream end c, the solid excrement will fall into the toilet chamber 31 first. The toilet chamber 31 is set at a higher position, which is beneficial for users to clean the toilet chamber 31 later, and will not come into contact with the sewage in the sludge collection chamber 32.

[0087] As the conveyor unit 331 moves, some of the liquid waste falls into the collection bin 32 due to gravity. The collection bin 32 is positioned low, facilitating the installation of a drainage structure on the base 1 for centralized treatment of liquid waste. The layered arrangement of the collection bin 32 and the toilet bin 31 ensures that their cleaning paths do not interfere with each other. Furthermore, since solid waste has already been collected by the toilet bin 31, the collection bin 32 is primarily composed of liquid waste. This prevents the drainage structure on the base 1 from being blocked by solid waste, thus ensuring smooth drainage.

[0088] It is understandable that when there is liquid in the excrement, some of the liquid will enter the septic tank 31. To improve the solid-liquid separation effect and increase cleaning convenience, in one embodiment, the second opening 321 of the sludge collection tank 32 is at least partially upward. The upward area is at least partially lower than the bottom of the septic tank 31, and their vertical projections at least partially overlap. A sieve groove communicating with the second opening 321 is provided at the bottom of the septic tank 31 in the overlapping area.

[0089] In this embodiment, the second opening 321 of the sludge collection chamber 32 partially overlaps with the bottom of the stool chamber 31, and a sieve groove communicating with the second opening 321 is provided at the overlapping area of ​​the bottom of the stool chamber 31. Thus, solid excrement remains in the stool chamber 31, while residual liquid excrement carried by it permeates through the sieve groove and flows into the lower sludge collection chamber 32 along the height difference between the stool chamber 31 and the sludge collection chamber 32. The sieve groove provides a channel for the liquid excrement to flow, preventing it from accumulating at the bottom of the stool chamber 31 and reducing the possibility of solid excrement being soaked or adhering to the chamber body. Simultaneously, the sieve groove only allows liquid to pass through; solid excrement, due to its larger volume, cannot fall and remains stably within the stool chamber 31, thereby improving the solid-liquid separation and collection effect.

[0090] As described above, the waste container 31 is placed inside the base 1 to collect at least a portion of the excrement. To facilitate cleaning of the waste container 31, in one embodiment, the waste container 31 is detachably installed inside the base 1. After the pet defecates, the user can promptly remove the waste container 31 from the base 1 and clean it, ensuring the cleanliness of the pet toilet 100 and thus improving the quality of the indoor environment.

[0091] It is understandable that when the transfer unit 331 transfers excrement to the toilet bowl 31, some excrement may remain in the transfer unit 331. In order to avoid contamination of the transfer unit 331 by the residual excrement, in one embodiment, the toilet bowl 31 is located at the downstream end c of the transfer assembly 33 to receive the transferred excrement, and a scraper 7 is provided between the first opening 311 of the toilet bowl 31 and the downstream end c.

[0092] The transfer unit 331 transfers the excrement to the downstream end c and places it into the toilet bowl 31. The scraper 7, located between the first opening 311 of the toilet bowl 31 and the downstream end c, scrapes the transfer unit 331 at the downstream end c, removing any remaining excrement, which then falls into the toilet bowl 31 from the first opening 311. This achieves secondary cleaning of the transfer unit 331.

[0093] It should be noted that the two technical features mentioned above, namely the detachable installation of the compartment 31 and the installation of the scraper 7, can be either selected or provided simultaneously. Specifically, in one embodiment, both technical features are provided simultaneously.

[0094] Continuing from the above, the transfer component 33 is configured as a conveyor belt assembly, and correspondingly, the transfer section 331 is a conveyor belt. At the downstream end c, a scraper 7 positioned between the first compartment opening 311 and the conveyor belt scrapes against the surface of the conveyor belt. Because the conveyor belt is flexible and deformable under force, the scraper 7 can only remove residual solid waste or solid-liquid mixtures from the conveyor belt when scraping it; it cannot completely remove residual liquid waste. The liquid waste will eventually drip into the collection bin 32 under gravity. In this way, solid-liquid separation of the waste can be further achieved.

[0095] The present invention does not impose specific limitations on the positional relationship between the scraper 7 and the transfer section 331. In one embodiment, the side of the scraper 7 may abut against the surface of the transfer section 331, facilitating the scraping off of solid-liquid mixed excrement. In another embodiment, a gap may be formed between the side of the scraper 7 and the surface of the transfer section 331, thereby facilitating the passage of liquid excrement adhering to the transfer section 331 through the gap and dripping into the collection bin 32 under gravity.

[0096] Furthermore, the present invention does not impose specific restrictions on the placement of the scraper 7. In one embodiment, the scraper 7 is directly disposed around the periphery of the first compartment opening 311 of the toilet compartment 31; after the scraper 7 scrapes off the excrement remaining on the transfer section 331, the scraped dirt can fall into the toilet compartment 31 along the scraper 7.

[0097] In another embodiment, there is no connection between the scraper 7 and the chamber 31. The two ends of the scraper 7 are fixed to the base 1 and suspended at the first chamber opening 311.

[0098] Continuing from the above, a partition 2 is installed around the defecation platform 11 to define the pet's defecation area a. In some applications, the partition 2 needs to be cleaned after the pet toilet 100 has been used for a period of time. In other applications, large dogs grow larger and exceed the defecation area a. In these cases, the partition 2 needs to be removed. For ease of user operation, the partition 2 is designed to be detachably installed on the base 1.

[0099] The enclosure 2 encloses a litter box 11 to define the litter area a. To facilitate pets' entry and exit from the litter area a, an entrance 21 for pets is provided on one side of the enclosure 2. The entrance 21 not only facilitates pets' entry and exit but also guides their movement path, making it more conducive to pets defecating in designated areas.

[0100] In some of the situations mentioned above, dogs sometimes urinate outside the designated elimination area a, causing inconvenience for the user. To avoid this, a partition 2 is installed that is at least partially higher than the elimination platform 11, forming a barrier-like structure around the platform 11. This effectively confines the pet's excrement within the elimination area a, eliminating the need for the user to clean the non-elimination area a and improving user convenience.

[0101] It should be noted that the above three technical features—the detachable installation of the enclosure 2, the setting of the entrance 21, and the partial elevation above the drainage platform 11—can be selected as one, two, or all at the same time. Specifically, in one embodiment, all three technical features are set simultaneously.

[0102] To completely prevent pet excrement from spilling outside the designated excretion area a, more specifically, the enclosure 2, except for the entrance 21, extends beyond the excretion platform 11. This creates a tight barrier around the excretion platform 11, keeping pet excrement within the designated excretion area a.

[0103] Continuing from the above, a partition 2 is installed that extends above the defecation platform 11, forming a barrier section. In some cases, when a pet defecates, its excrement may spill directly onto the inner wall of the barrier section.

[0104] To ensure the cleanliness of the fenced area, please refer to [link / reference needed]. Figure 4 The pet toilet 100 also includes a flushing assembly 4, which is located on the enclosure 2 and is used to flush the inner wall of the enclosure section.

[0105] When excrement spills onto the inner wall of the enclosure section, in order to prevent the excrement from flowing along the gaps to other areas of the base 1, the pet toilet 100 also includes a guide section 15. The guide section 15 protrudes from the inner wall of the base 1 and at least partially overlaps with the projection of the transfer section 331 in the vertical direction, so as to guide the liquid flowing down from the inner wall of the enclosure section to the transfer section 331.

[0106] It should be noted that the two technical features mentioned above, the rinsing component 4 and the flow guide 15, can be provided individually or simultaneously. Specifically, in one embodiment, both technical features are provided simultaneously.

[0107] A guide section 15 is provided on the inner wall of the base 1. Since the projection of the guide section 15 and the transfer section 331 in the vertical direction at least partially overlaps, when a pet spills liquid excrement onto the inner wall of the enclosure section, the liquid excrement flows down the inner wall of the enclosure section and can be guided by the guide section 15 to the transfer section 331. Through the transfer section 331, it finally enters the waste container 31 and / or the waste collection container 32. In this way, liquid excrement can be prevented from flowing through gaps to other parts of the base 1 and contaminating the interior of the base 1.

[0108] Furthermore, the flushing assembly 4 on the enclosure 2 can flush the inner wall of the enclosure section. The flushed liquid will also flow down the inner wall of the enclosure section. Similarly, the liquid flowing down the inner wall of the enclosure section can be guided by the guide section 15 to the transfer section 331, and then transferred to the sludge collection tank 31 and / or the sludge collection tank 32. In this way, it is possible to prevent flushing wastewater from flowing from the gaps to other parts of the base 1 and contaminating the interior of the base 1.

[0109] Continuing from the above, the transfer assembly 33 has an upstream end b and a downstream end c in its transfer direction. The transfer section 331 circulates between the upstream end b and the downstream end c, and has a return path from the downstream end c to the upstream end b. That is, after the moving part transfers the excrement to the sludge bin 31 and / or the waste collection bin 32, the transfer section 331 is in an unloaded state. At this time, the transfer section 331 can flow from the downstream end c to the upstream end b to carry excrement again, thereby realizing the cyclical flow of the transfer section 331. Its stroke can be exemplified by a conveyor belt.

[0110] Understandably, in some cases, excrement residue may remain on the transfer section 331 after it has transferred the waste. The pet toilet 100 also includes a water spray structure 5, which is located on the return path and sprays water to clean the empty transfer section 331 on the return journey. By spraying water to clean the empty transfer section 331 on the return path, residual excrement is removed, ensuring that the transfer section 331 flowing to the upstream end b is free of excrement residue. Thus, cleaning the transfer section 331 after a pet completes one excretion not only prevents contamination of the pet toilet 100 due to excrement residue but also prepares the space for the next pet excretion.

[0111] This invention does not impose specific limitations on the water intake method of the water spray structure 5. In one embodiment, the water spray structure 5 has a built-in water storage component, which supplies water to the water spray structure 5. The user can add water to the water storage component at regular intervals.

[0112] In one embodiment, an external water source is provided outside the pet toilet 100. The pet toilet 100 also includes a water supply component 61, such as a water supply pipe, located on the base 1. The water supply pipe connects the water spray structure 5 to the external water source, thereby supplying water to the water spray structure 5.

[0113] This invention does not impose specific limitations on the form of the external water source. In one embodiment, please refer to [reference needed]. Figure 5 The pet toilet 100 is located indoors near a water pipe, and the external water source is the outlet of a tap water pipe. In another embodiment, the pet toilet 100 also includes a water tank 611 externally mounted on the base 1. The water tank 611 stores clean water, and the clean water in the water tank 611 is delivered to the water spray structure 5 by the water supply assembly 61.

[0114] This invention does not impose specific restrictions on the placement of the water spray structure 5. Based on the structure in the above embodiments, the transfer component 33 is configured as a conveyor belt assembly. The conveyor belt is located in the lower empty section 3312, which has a return path from the downstream end c to the upstream end b. The water spray structure 5 can be positioned corresponding to the empty section 3312.

[0115] In one embodiment, the conveyor belt assembly further includes a first tensioner and a second tensioner. The first tensioner is disposed near the downstream end c. An unloaded section 3312 is sunken, bent, and wound around the first tensioner to form a first unloaded section on the side of the first tensioner near the downstream end. The second tensioner is located between the upstream end b and the first tensioner, and its position is higher than the first tensioner, to form a second unloaded section between the two tensioners and a third unloaded section between the second tensioner and the upstream end.

[0116] Because the first tensioning element is positioned lower than the downstream end, the first unloaded section is inclined downwards. As the conveyor belt transports waste past the downstream end, solid waste is transferred to the waste collection bin 31. Liquid waste adheres to the conveyor belt and passes the downstream end. At this time, the liquid waste is located in the first unloaded section. Because the first unloaded section is inclined downwards, some of the liquid waste adhering to it easily drips off due to gravity and enters the waste collection bin 32.

[0117] Some liquid waste flows along the conveyor belt to the first tensioner. Because the second tensioner is positioned higher than the first tensioner, the second unloaded section is inclined upwards. As the conveyor belt passes the first tensioner, the remaining liquid waste on it continues to drip into the sludge collection bin under gravity after passing the inflection point of the first tensioner.

[0118] At this point, the liquid waste on the conveyor belt is mostly collected in the sludge collection bin. After passing the first tensioner, the conveyor belt forms a second empty section. At this point, there is no liquid waste on the second empty section, but there will be a residual film layer formed by the liquid waste. To further clean the conveyor belt, a water spray structure 5 is positioned corresponding to the second empty section, spraying water towards the second empty section to thoroughly clean the conveyor belt.

[0119] The present invention does not impose specific restrictions on the orientation of the water spray structure 5. The water spray structure 5 can be arranged horizontally or vertically. The water spray structure 5 is located below the second unloaded section, and a water spray nozzle is provided on its top to spray water toward the second unloaded section.

[0120] The water spray structure 5 can also be arranged at an angle. As mentioned above, the second unloaded section is arranged at an angle, and the water spray structure 5 is set parallel to the second unloaded section. Water spray nozzles are set on its surface opposite to the second unloaded section. In this way, the water spray area of ​​the water spray structure 5 on the second unloaded section can be increased, thereby enhancing the cleaning effect of the second unloaded section.

[0121] Furthermore, pet excrement can be transferred to the waste bin 31 and the waste collection bin 32 via the transfer component 33 for collection, thereby preventing excrement from contaminating the interior of the base 1. The base 1 has a built-in water spray structure 5 to spray water to clean the transfer section 331 on the return path. To prevent wastewater generated after cleaning the transfer section 331 from contaminating the interior of the base 1, a wastewater receiving component is required.

[0122] The water spray area of ​​the spray structure 5 can be covered by setting the first opening 311 of the waste collection chamber 31, or by setting the second opening 321 of the waste collection chamber 32 to cover the water spray area of ​​the spray structure 5, or by setting both the first opening 311 and the second opening 321 to cover the water spray area of ​​the spray structure 5. In this way, the wastewater generated after the cleaning transfer unit 331 can be collected, ensuring the cleanliness of the inside of the base 1.

[0123] It should be noted that the above two technical features, the water supply component 61 and the coverage of the spray area, can be configured individually or simultaneously. Specifically, in one embodiment, both technical features are configured simultaneously.

[0124] In accordance with the structure described in the above embodiments, the sludge collection chamber 32 is positioned at a low level to facilitate the discharge of liquid waste within it. To facilitate the discharge of wastewater, in one embodiment, the second opening 321 of the sludge collection chamber 32 is positioned upwards and covers the spray area of ​​the spray structure 5. The base 1 has a drain outlet 621 to connect the sludge collection chamber 32 to external sewage discharge equipment.

[0125] In this embodiment, the second opening 321 is positioned upwards and covers the spray area of ​​the spray structure 5. After the spray structure 5 sprays water to clean the transfer section 331, the generated wastewater can flow into the sludge collection bin 32 by gravity for centralized treatment, instead of flowing to other areas of the base 1, thus ensuring the cleanliness of the base 1. At the same time, the liquid waste concentrated in the sludge collection bin 32 can be discharged through the drain outlet 621, thereby achieving timely cleaning of the sludge collection bin 32 and avoiding bacterial growth and odor caused by the accumulation of waste.

[0126] This invention does not impose specific limitations on the sewage discharge method of the sludge collection tank 32. In one embodiment, the pet toilet 100 is located near the indoor sewer and is connected to the drain outlet 621 and the sewer via a sewage pipe, thereby achieving sewage treatment of the sludge collection tank 32. In another embodiment, please refer to... Figure 6 The pet toilet 100 also includes a wastewater tank 622 externally mounted on the base 1. Liquid waste in the waste collection chamber 32 is collected in the wastewater tank 622 through the drain outlet 621 and is finally discharged and disposed of by the user.

[0127] The present invention also provides a pet toilet 100, please refer to [link / reference]. Figure 2 and Figure 3The pet toilet 100 includes a base 1. The base 1 has an inner cavity 13 and a litter box 11 for holding the pet, the litter box 11 being at least partially defined as a litter area. In this way, the pet is confined to the litter area a on the litter box 11 to defecate, thereby achieving fixed-point defecation for the pet.

[0128] The excretion platform 11 has at least one perforated structure 12 in the excretion area a that communicates with the inner cavity 13. The pet toilet 100 also includes a collection mechanism 3 housed in the inner cavity 13, the collection mechanism 3 including a feces tank 31, a transfer component 33 and a waste collection tank 32.

[0129] After a pet defecates on the litter box 11, the excrement falls through the perforated structure 12 onto the transfer assembly 33 inside the base 1 and is then transferred to the waste container 31 and / or the waste collection container 32. This not only effectively isolates the pet from the excrement, preventing the pet from ingesting it or getting it on its body, but also allows for timely collection and disposal of the excrement, preventing it from being exposed to the indoor environment and improving indoor environmental quality.

[0130] The present invention does not impose specific limitations on the form of the transfer component 33. The transfer component 33 can be configured as a flexible transmission component. Taking the transfer component 33 as a conveyor belt assembly as an example, the conveyor belt of the conveyor belt assembly serves as the transfer part 331 for transferring excrement. The transfer component 33 has an upstream end b and a downstream end c in its transfer direction.

[0131] Understandably, pet excrement is typically in solid, liquid, or mixed solid-liquid states. A waste bin 31 and a waste collection bin 32 are located at the downstream end c of the conveyor assembly 33. When the conveyor belt transports solid excrement, the excrement, due to the inertia of the conveyor belt, falls into the waste bin 31 at the downstream end c in a parabolic trajectory. When the conveyor belt transports mixed solid-liquid excrement, some of the solid excrement is sent to the waste bin 31, while some of the liquid excrement, as the conveyor belt passes the corner at the downstream end c, flows down naturally due to gravity and is collected by the waste collection bin 32. When the conveyor belt transports liquid excrement, some of the liquid excrement is sent to the waste bin 31; while the remaining liquid excrement on the conveyor belt, as it passes the corner at the downstream end c, flows down naturally due to gravity and is collected by the waste collection bin 32.

[0132] In other words, the transfer component can transfer excrement into the feces chamber 31; the transfer component can transfer excrement into the waste collection chamber 32; the transfer component can also transfer excrement into both the feces chamber 31 and the waste collection chamber 32 simultaneously. Thus, through the combined action of the feces chamber 31 and the waste collection chamber 32, excrement can be completely collected, thereby improving the cleaning effect of the pet toilet 100.

[0133] Furthermore, after the excrement is transferred by the transfer unit 331, the waste collection chamber 31 is used to collect at least a portion of the pet's solid excrement, and the waste collection chamber 32 is used to collect at least a portion of the pet's liquid excrement.

[0134] In this way, solid-liquid separation can be achieved during excrement collection. The liquid excrement entering the waste collection chamber 32 can be quickly sealed or diverted, thereby reducing the diffusion of ammonia gas produced by the decomposition of liquid excrement. After solid-liquid separation, the dried solid excrement is not conducive to bacterial growth, and the separate storage of liquid excrement also reduces cross-contamination of bacteria. Furthermore, the dried solid excrement in the waste chamber 31 can be directly picked up and cleaned, and the liquid excrement in the waste collection chamber 32 can be discharged separately. Users do not need to deal with viscous mixtures, thus reducing the difficulty of cleaning the pet toilet.

[0135] After the excrement falls from the drain structure 12 to the transfer assembly 33, in order to ensure that the excrement falls accurately into the chamber 31, the first opening 311 of the chamber 31 is at least partially lower than the top of the downstream end c on the side near the downstream end c, and the projections of the two in the vertical direction at least partially overlap.

[0136] The first opening 311 of the urinal 31 is at least partially lower than the top of the downstream end c. This not only allows it to directly receive the excrement falling from the downstream end c, preventing it from deviating or falling out of the urinal 31 due to inertia, but also the natural drop between the downstream end c and the first opening 311 allows the excrement to slide into the urinal 31 along the height difference after it is transported to the downstream end c by the transfer component 33, without the need for additional power.

[0137] Meanwhile, to prevent some excrement from scattering or flowing out from the gap between the periphery of the first compartment opening 311 and the downstream end c, the vertical projections of the first compartment opening 311 and the downstream end c are designed to at least partially overlap. This partial overlap forms a receiving barrier, ensuring that even if excrement shifts due to inertia or is stuck to the end of the conveyor belt, it will be intercepted by the overlapping area, preventing it from falling into the gap between the two compartments or outside the equipment. Furthermore, this partial overlap shortens the falling distance of excrement from the downstream end c to the first compartment opening 311, reducing the possibility of it scattering or tumbling in the air, allowing it to slide more smoothly into the toilet compartment 31 and reducing the risk of stagnation.

[0138] As mentioned above, when the excrement is a solid-liquid mixture or liquid, some of the liquid excrement may not be able to enter the toilet bowl 31 and instead enters the sludge collection chamber 32 due to gravity. Understandably, a drain outlet 621 or a drain pipe is usually installed to drain and clean the sewage in the sludge collection chamber 32.

[0139] The second opening 321 of the sludge collection chamber 32 is at least partially lower than the bottom of the toilet chamber 31. When the excrement is transferred to the downstream end c, the solid excrement will fall into the toilet chamber 31 first. The toilet chamber 31 is set at a higher position, which is beneficial for users to clean the toilet chamber 31 later, and will not come into contact with the sewage in the sludge collection chamber 32.

[0140] As the conveyor unit 331 moves, some of the liquid waste falls into the collection bin 32 due to gravity. The collection bin 32 is positioned low, facilitating the installation of a drainage structure on the base 1 for centralized treatment of liquid waste. The layered arrangement of the collection bin 32 and the toilet bin 31 ensures that their cleaning paths do not interfere with each other. Furthermore, since solid waste has already been collected by the toilet bin 31, the collection bin 32 is primarily composed of liquid waste. This prevents the drainage structure on the base 1 from being blocked by solid waste, thus ensuring smooth drainage.

[0141] Furthermore, the second opening 321 of the waste collection chamber 32 at least partially overlaps with the vertical projection of the bottom of the feces chamber 31. When liquid excrement falls, even if it lands outside the feces chamber 31, it will drip into the second opening 321, thus ensuring that the excrement can be completely collected without contaminating the inner cavity 13 of the base 1.

[0142] It should be noted that the two technical features mentioned above, namely, the first compartment opening 311 and the downstream end c at least partially overlap, and the second compartment opening 321 and the bottom of the storage compartment 31 at least partially overlap, can be either selected or provided simultaneously. Specifically, in one embodiment, both technical features are provided simultaneously.

[0143] It is understandable that when there is liquid excrement in the waste, some of the liquid excrement will enter the septic tank 31. In order to improve the solid-liquid separation effect and increase the convenience of cleaning, in one embodiment, the second opening 321 of the sludge collection tank 32 at least partially overlaps with the bottom of the septic tank 31, and at least at the overlapping position, the bottom of the septic tank 31 is provided with a sieve groove that communicates with the second opening 321 of the sludge collection tank 32, so that at least some of the liquid excrement inside flows into the sludge collection tank 32.

[0144] In this embodiment, the second opening 321 of the sludge collection chamber 32 partially overlaps with the bottom of the stool chamber 31, and a sieve groove communicating with the second opening 321 is provided at the overlapping area of ​​the bottom of the stool chamber 31. Thus, solid excrement remains in the stool chamber 31, while residual liquid excrement carried by it permeates through the sieve groove and flows into the lower sludge collection chamber 32 along the height difference between the stool chamber 31 and the sludge collection chamber 32. The sieve groove provides a channel for the liquid excrement to flow, preventing it from accumulating at the bottom of the stool chamber 31 and reducing the possibility of solid excrement being soaked or adhering to the chamber body. Simultaneously, the sieve groove only allows liquid to pass through; solid excrement, due to its larger volume, cannot fall and remains stably within the stool chamber 31, thereby improving the solid-liquid separation and collection effect.

[0145] In order to further improve the solid-liquid separation effect in the septic tank 31, in one embodiment, the bottom of the septic tank 31 is inclined downward in the direction near the downstream end c, and the septic tank 31 overlaps with the sludge collection tank 32 at least at its lower end, and the screen is set near the lower end.

[0146] When solid-liquid mixed waste or liquid waste is transferred to the waste bin 31, the liquid waste is guided by gravity to flow towards the lower end due to the downward slope of the bottom of the waste bin 31, thus preventing the liquid waste from accumulating at various points on the bottom of the bin. The sieve is positioned close to the lower end, so the liquid waste flows directly into the sieve without needing to disperse or permeate, allowing the liquid waste to quickly pass through the sieve into the waste collection bin 32. This not only results in higher separation efficiency but also keeps the waste bin 31 dry, reducing the possibility of prolonged mixing and fermentation of waste.

[0147] Meanwhile, the bottom of the chamber 31 is inclined, allowing liquid waste to drain quickly, while solid waste is less likely to adhere to the bottom of the chamber for extended periods and is not soaked in liquid. This makes the waste easier to remove during cleaning, reducing the risk of residue buildup. Furthermore, the lower end of the chamber 31 overlaps with the sludge collection chamber 32, allowing the collected liquid waste to fall directly into the sludge collection chamber 32 through a sieve at this location, preventing the liquid from deviating during its descent and reducing leakage.

[0148] It is understandable that when the transfer component 33 transfers excrement to the waste container 31, some excrement may remain in the transfer component 33. To prevent the residual excrement from contaminating the transfer component 33, in one embodiment, the first opening 311 of the waste container 31 partially overlaps with the downstream end c. The pet toilet 100 also includes a scraper 7, which is disposed at the first opening 311 of the waste container 31 and located in the overlapping area between the first opening 311 and the downstream end c.

[0149] The transfer component 33 transfers the excrement to the downstream end c and places it into the waste container 31. A scraper 7 is installed at the overlapping area between the first opening 311 of the waste container 31 and the downstream end c. This scraper can scrape the transfer component 33 at the downstream end c, removing any remaining excrement, which then falls into the waste container 31 from the first opening 311. This achieves secondary cleaning of the transfer component 33.

[0150] The litter box 31 is placed inside the base 1 to collect at least a portion of the excrement. To facilitate cleaning of the litter box 31, in one embodiment, an insertion port communicating with the inner cavity 13 is formed on the base 1, through which the litter box 31 is movably inserted into the inner cavity 13. After the pet defecates, the user can promptly pull the litter box 31 out of the insertion port and clean it, ensuring the cleanliness of the pet toilet 100 and thus improving the quality of the indoor environment.

[0151] The present invention does not impose specific restrictions on the location of the insertion port or the insertion method of the toilet compartment 31. In one embodiment, the insertion direction of the toilet compartment 31 is parallel to the transfer direction of the transfer component 33. In another embodiment, the insertion direction of the toilet compartment 31 is intersecting the transfer direction of the transfer component 33.

[0152] As mentioned above, the defecation platform 11 on the base 1 is used to support the pet and allow the pet to defecate on the platform 11. This invention does not impose specific limitations on the structure of the defecation platform 11. In one embodiment, the defecation platform 11 is configured as a support plate 16, which has multiple through holes to form a perforated structure 12.

[0153] It is understandable that the pet's defecation point within the defecation area a is not fixed. To ensure that excrement falls into the inner cavity 13 promptly, rather than accumulating on the defecation area a, in one embodiment, the defecation platform 11 is configured as a mesh plate. The mesh plate includes an outer frame and multiple ribs disposed within the outer frame, the ribs crisscrossing to form multiple mesh openings. The outer frame and the multiple ribs can support the pet. The mesh openings formed by the crisscrossing ribs are dense and relatively large, and will not obstruct the fall of excrement.

[0154] After the pet finishes defecating on the litter box 11, the excrement falls through the drain hole structure 12, and some of it remains on the litter box 11. In order to keep the pet toilet 100 clean, the litter box 11 needs to be cleaned.

[0155] In one embodiment, please refer to Figure 2 The base 1 has an opening 14 at its top that connects to the inner cavity 13. A mesh plate is detachably installed at the opening 14 of the inner cavity 13 to form a litter box 11. The mesh of the mesh plate forms a perforated structure 12. After the pet has finished defecating, if the user finds excrement residue on the mesh plate, the user can remove the mesh plate for cleaning, thus facilitating the pet's next defecation.

[0156] Furthermore, when a pet defecates on the grid plate, its defecation point within the defecation area a is uncertain. To ensure complete collection of excrement, the waste container 31 and the transfer component 33 are located below the grid plate, with the first opening 311 of the waste container 31 facing upwards and covering the mesh openings of the grid plate together with the transfer component 33. In other words, the grid plate not only covers the transfer component 33 but also extends partially to the first opening 311 of the waste container 31, with its mesh openings corresponding to the transfer component 33 and the first opening 311. Thus, even if the pet does not defecate directly into the transfer component 33, its excrement will fall directly into the waste container 31 through the mesh openings.

[0157] As mentioned in the above embodiments, a defecation area a is formed on the defecation platform 11 for the pet to defecate, thereby achieving the pet's designated defecation point. This invention does not specifically limit the method in which the defecation area a is formed.

[0158] In one embodiment, please refer to Figure 1 The pet toilet 100 also includes a perimeter panel 2, which surrounds the toilet platform 11 to form a toilet area a. This confines the pet to the toilet area a, allowing it to defecate in a designated spot. The perimeter panel 2 also provides an entrance / exit 21 for the pet to enter and exit the toilet area a; this not only facilitates entry and exit but also guides the pet's movement, further promoting designated toileting.

[0159] Specifically, the enclosure 2 surrounds multiple sides of the litter box 11, defining the pet's litter area a. The enclosure 2 is open at one side of the litter box 11 to form an entrance 21.

[0160] In some of the situations mentioned above, dogs sometimes urinate outside the designated elimination area a, causing inconvenience for the user. To avoid this, a partition 2 is installed that is at least partially higher than the elimination platform 11, forming a barrier-like structure around the platform 11. This effectively confines the pet's excrement within the elimination area a, eliminating the need for the user to clean the non-elimination area a and improving user convenience.

[0161] To completely prevent pet excrement from spilling outside the designated excretion area a, more specifically, the enclosure 2, except for the open side, extends beyond the excretion platform 11. This creates a tight barrier around the excretion platform 11, keeping pet excrement within the designated excretion area a.

[0162] Continuing from the above, a partition 2 is installed that extends above the defecation platform 11, forming a barrier section. In some cases, when a pet defecates, its excrement may spill directly onto the inner wall of the barrier section.

[0163] To ensure the cleanliness of the fenced area, please refer to [link / reference needed]. Figure 4 The pet toilet 100 also includes a flushing component 4, which is provided at least in a partial area of ​​the enclosure 2 protruding from the excretion platform 11, for spraying and cleaning the inner wall of the enclosure 2.

[0164] Meanwhile, the enclosure 2 has a built-in water inlet channel that connects to the flushing assembly 4, supplying water to the flushing assembly 4 through the water inlet channel. This eliminates the need for complex piping around the base 1, reducing the overall space occupied by the pet toilet 100.

[0165] When excrement spills onto the inner wall of the enclosure section, in order to prevent the excrement from flowing along the gaps to other areas of the base 1, the pet toilet 100 also includes a guide section 15. The guide section 15 protrudes from the inner wall of the base 1 and is arranged around the circumference of the base 1. The outlet end of the guide section 15 at least partially overlaps with the projection of the transfer assembly 33 in the vertical direction, so as to guide the liquid flowing down from the inner wall of the enclosure section to the transfer section 331.

[0166] It should be noted that the two technical features mentioned above, the rinsing component 4 and the flow guide 15, can be provided individually or simultaneously. Specifically, in one embodiment, both technical features are provided simultaneously.

[0167] A guide section 15 is provided on the inner wall of the base 1. Since the outlet end of the guide section 15 at least partially overlaps with the vertical projection of the transfer component 33, when a pet spills liquid excrement onto the inner wall of the enclosure section, the liquid excrement flows down the inner wall of the enclosure section and can be guided to the transfer component 33 via the guide section 15. Through the transfer component 33, it finally enters the waste container 31 and / or the waste collection container 32. In this way, liquid excrement can be prevented from flowing through gaps to other parts of the base 1 and contaminating the interior of the base 1.

[0168] Furthermore, the flushing assembly 4 on the enclosure 2 can flush the inner wall of the enclosure section. The flushed liquid will also flow down the inner wall of the enclosure section. Similarly, the liquid flowing down the inner wall of the enclosure section can be guided by the guide section 15 to the transfer assembly 33, and then transferred to the sludge chamber 31 and / or the sludge collection chamber 32. In this way, it is possible to prevent flushing wastewater from flowing from the gaps to other parts of the base 1 and contaminating the interior of the base 1.

[0169] In another embodiment, please refer to Figure 6 The base 1 has an opening 14 at its top that connects to its inner cavity 13. The pet toilet 100 also includes a cage 8, which is mounted on top of the base 1 and covers the opening 14. The interior of the cage 8 forms a defecation area a, and its bottom forms a defecation platform 11 at the opening 14. The cage 8 is provided with an entrance and exit 21 for the pet to enter and exit the cage.

[0170] In some applications, pets are kept in cages for daily activities. The cage 8 is placed directly on the base 1. The bottom of the cage 8 not only supports the pet but also serves as a defecation platform 11 for the pet to relieve itself. In this case, the interior of the cage 8 is not only the pet's activity area but also its defecation area a.

[0171] Understandably, the cage 8 is typically formed by a mesh panel. When a pet defecates at the bottom of the cage 8, the excrement can fall directly into the transfer component 33 inside the base 1 through the mesh openings. Furthermore, when the pet engages in daily activities within the cage 8, food scraps, residual liquids, and shed hair can all fall through the mesh openings into the transfer component 33, which then transports them to the waste collection tray 31 and the waste collection tray 32, thus ensuring that the cage 8 remains clean and free of excrement and other debris.

[0172] Meanwhile, an entrance 21 is provided on the cage 8 for the pet to enter and exit the excretion area a; this not only makes it convenient for the pet to enter and exit the cage 8, but also guides the pet's movement path and is more conducive to the pet's fixed-point excretion.

[0173] The present invention does not impose specific limitations on the installation method of the cage 8. The cage 8 can be fixedly installed on the base 1, for example, by welding. The cage 8 can also be detachably installed on the base 1, for example, by bolts, buckles, or other locking mechanisms.

[0174] Continuing from the above, the transfer assembly 33 has an upstream end b and a downstream end c in its transfer direction. The transfer section 331 circulates between the upstream end b and the downstream end c, and the transfer section 331 has a return path from the downstream end c to the upstream end b. Taking a conveyor belt assembly as an example, the conveyor belt has a carrying section 3311 for transferring excrement, and the carrying section 3311 has a working path from the upstream end b to the downstream end c. The conveyor belt has an empty section 3312 located below the carrying section 3311, and the empty section 3312 has a return path from the downstream end c to the upstream end b.

[0175] Understandably, in some cases, excrement residue may remain on the transfer section 331 after it has transferred the excrement. The pet toilet 100 also includes a water spray structure 5 built into the base 1, which is configured to clean the empty section 3312 by spraying water. By cleaning the empty transfer section 331 on the return path by spraying water, residual excrement is removed, ensuring that the transfer section 331 flowing to the upstream end b is free of excrement residue. Thus, cleaning the transfer section 331 after the pet has finished defecating not only prevents contamination of the pet toilet 100 due to excrement residue, but also prepares the space for the next pet's defecation.

[0176] In accordance with the structure described in the above embodiments, the sludge collection chamber 32 is positioned at a low level to facilitate the discharge of liquid sludge from the sludge collection chamber 32. To facilitate the discharge of cleaning wastewater, in one embodiment, the second opening 321 of the sludge collection chamber 32 is positioned upwards and covers the spray area of ​​the spray structure 5.

[0177] In this embodiment, the second compartment 321 is set upward and covers the spray area of ​​the spray structure 5. After the spray structure 5 sprays water to clean the transfer part 331, the generated sewage can flow into the sludge collection compartment 32 by gravity and be centrally treated, instead of flowing to other areas of the base 1, thereby ensuring the cleanliness of the inside of the base 1.

[0178] In one embodiment, please refer to Figure 5 The pet toilet 100 also includes a water supply component 61 and a sewage discharge component 62 located on the base 1. The water supply component 61 is connected to the water spray structure 5 and an external water source, and the sewage discharge component 62 is connected to the sewage collection chamber 32 and an external sewage discharge device.

[0179] This invention does not impose specific limitations on the sewage discharge method of the sludge collection tank 32. In one embodiment, the pet toilet 100 is located near the indoor sewer and is connected to the sewage discharge component 62 and the sewer via a sewage pipe, thereby achieving sewage treatment of the sludge collection tank 32. In another embodiment, please refer to... Figure 6 The pet toilet 100 also includes a wastewater tank 622 externally mounted on the base 1. Liquid waste in the waste collection chamber 32 is collected in the wastewater tank 622 through the drain outlet 621 and is finally discharged and disposed of by the user.

[0180] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made under the concept of the present invention using the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
