Description

Technical Field

[0001] This utility model relates to the field of pet supplies technology, and in particular to a pet toilet device. Background Technology

[0002] In places where pets are kept, pet toileting facilities are provided to facilitate the pets' use of the litter box. Taking a cat toileting facility (sometimes referred to as a "litter box" for ease of explanation) as an example, a typical litter box usually has a compartment for the cat to use (sometimes called a "litter chamber" for ease of explanation). To prevent cat excrement from contaminating the main body of the compartment, the compartment is usually lined with excrement-aggregating granules (such as cat litter). After the cat defecates in the compartment, the excrement combines with the cat litter to form clumps. When cleaning the inside of the compartment is needed, these clumps of cat litter are removed, thus cleaning up the cat excrement along with the litter.

[0003] Because litter box chambers often have a strong odor from excrement, some manufacturers have proposed a method to reduce the workload for cat owners. This involves rotating the chamber and using a sieve to separate clumps of litter from clean, granular litter, thus cleaning the clumps. In these rotating litter boxes, the chamber is typically supported directly on the bottom for rotation. While this rotating chamber method can reduce odor to some extent, the odor tends to worsen over time, and bacteria can easily proliferate. To address this, some existing litter boxes incorporate air purification systems. However, because the chamber is entirely exposed and rotating, the air purification system needs to be able to directly interface with the rotating chamber. The limited number of possible interfaces results in relatively low purification efficiency. Utility Model Content

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying juxtaposition of importance, or implicitly indicating the number of indicated technical features or their sequential relationship.

[0029] In the description of this embodiment, unless otherwise explicitly limited, terms such as setting, installing, and connecting should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this embodiment in conjunction with the specific content of the technical solution.

[0030] The following is for reference Figures 1 to 6 This describes a pet toileting device according to an embodiment. It should also be noted that the accompanying drawings have been optimized to some extent for ease of illustration. For example, in... Figure 2 In the diagram, for ease of illustration of the air purification system 400, a portion of the first housing 251 and the base 101 within the outer casing 203 are cut open. Figure 3For ease of illustration, only the area of ​​the first entrance / exit 206 is shown. Figure 4 In this illustration, for the sake of clarity, the second housing 252 of the outer casing 203 has been removed. Figure 5 In order to make it easier to illustrate filter 404, filter 404 is pulled out from base 101.

[0031] Main reference Figure 1 as well as Figure 2 The pet toileting device according to the embodiment includes a housing 203, a chamber 204, and an air purification system 400. A first mounting cavity 248 is formed within the housing 203, and the first mounting cavity 248 has a first inlet / outlet 206. The chamber 204 is rotatably mounted within the first mounting cavity 248 and is at least partially enclosed by the housing 203. The chamber 204 forms a toileting space 201, and the toileting space 201 has a second inlet / outlet 202 through which a pet can enter and exit the toileting space 201. The air purification system 400 is at least partially disposed within the housing 203, with its suction end positioned opposite the second inlet / outlet 202, and its discharge end connected to the outside of the housing 203.

[0032] The pet toileting device of this embodiment can improve the air purification efficiency within the chamber 204. Specifically, in this embodiment, by positioning the suction end of the air purification system 400 opposite to the second inlet / outlet 202 of the chamber 204, the area covered by the suction end of the air purification system 400 can be greatly expanded, thereby improving the purification efficiency of the air purification system 400. This improves the air purification efficiency of the toileting space 201 within the chamber 204. Furthermore, since the suction end of the air purification system 400 is positioned opposite to the second inlet / outlet 202 of the chamber 204, the diffusion of odors from the chamber 204 from the second inlet / outlet 202 to the outside of the pet toileting device can also be suppressed.

[0033] Continue to refer to Figure 1 as well as Figure 2 and supplementary reference Figure 5The pet toileting device described in this embodiment can be a house-type device. Pets using this device may include, for example, cats, dogs, rabbits, hamsters, etc. Typically, when the pet toileting device is used for cats' toileting behavior, it is sometimes referred to as a "litter box." In addition to the outer casing 203, the chamber 204, and the air purification system 400 (for ease of explanation, the overall structure including these components will sometimes be referred to as the "chamber section 200"), the pet toileting device may also include a base 100, which is supported on a floor or table, or any location where the pet can easily enter and exit. The base 100 includes a base 101, which forms a collection space 102 for collecting pet excrement. The chamber section 200 can be provided as a house on the base 101 of the base 100. In addition, an opening 103 is formed between the base 100 and the cabin portion 200. The opening 103 includes a portion formed on the base 101 and a portion formed on the outer shell 203. The opening 103 can be opened or closed, for example, through a door portion 500 having a double-door structure.

[0034] The outer shell 203 of the cabin section 200 is supported on the base 101 of the base base 100 and communicates with the collection space 102 via the opening 103. A support assembly 226 for rotatably supporting the cabin 204 may be provided on the outer shell 203, and the support assembly 226 acts as a bearing seat. The type of support assembly 226 is not particularly limited; for example, it may include side support rollers on both sides of the cabin 204 in the width direction (i.e., the left-right direction in the drawing). Correspondingly, support shafts 227 may be formed on both sides of the cabin 204 in the width direction, and the cabin 204 is supported on the support rollers via the support shafts 227. The support shafts 227 are connected to a motor 229 via, for example, a transmission mechanism 228 (e.g., a gear transmission mechanism). Thus, when the motor 229 operates, the support shafts 227 of the drive body 205 rotate around the support assembly 226, which acts as a bearing seat, thereby realizing the rotation of the cabin 204. When the chamber 204 is rotated (e.g., counterclockwise) until the second inlet / outlet 202 and the first inlet / outlet 206 are in approximately the same position, the pet can enter and exit the toilet space 201. When the chamber 204 is rotated (e.g., clockwise) until the second inlet / outlet 202 and the opening 103 are connected, excrement falls from the chamber 204 and through the opening 103 into the collection space 102.

[0035] The outer shell 203 and the compartment 204 are approximately hemispherical in shape. In other words, the first inlet / outlet 206 is formed by a cross-section approximately transversely cutting through the center of the outer shell 203. Similarly, the second inlet / outlet 202 of the compartment 204 is also formed by a cross-section approximately transversely cutting through the center of the compartment 204. The overall size of the compartment 204 is smaller than the overall size of the outer shell 203, allowing the compartment 204 to be fully accommodated within the first mounting cavity 248 and enclosed by the outer shell 203. When the pet toilet device is in a state where the pet can use it normally, the outer periphery of the compartment 204 is entirely enclosed by the outer shell 203, and the second inlet / outlet 202 of the compartment 204 and the first inlet / outlet 206 of the outer shell 203 are opposite each other. Furthermore, when viewed from above, the upper edge of the outer shell 203 near the first inlet / outlet 206 coincides with the toilet space 201 of the compartment 204. That is, when the compartment 204 is in a state where normal toilet use is possible, the upper edge of the outer shell 203 near the first inlet / outlet 206 extends above the first inlet / outlet 206. When the compartment 204 needs to be cleaned and is rotated, when viewed from the side (left / right) perspective, as the compartment 204 rotates (e.g., clockwise), a portion (e.g., the lower front) may protrude from the first inlet / outlet 206 of the outer shell 203. Moreover, as the compartment 204 rotates, when viewed from above, the upper edge of the outer shell 203 near the first inlet / outlet 206 always coincides with the toilet space 201 of the compartment 204.

[0036] The outer shell 203 has a hollow layer 272, within which a second mounting cavity 253 is formed. The outer shell 203 mainly includes a first shell 251 and a second shell 252, which overlap each other to form the hollow layer 272. The first shell 251 and the second shell 252 can be integrally manufactured by known processing methods such as injection molding, but are not limited thereto. For example, from the perspective of reducing processing difficulty and improving aesthetics, the first shell 251 and the second shell 252 can be assembled from multiple smaller shells. The first shell 251 is located on the outside of the outer shell 203, and the second shell 252 is located on the inside of the outer shell 203. The first shell 251 wraps around the second shell 252 from the outside. The overall appearance of the first shell 251 is a smooth hemispherical shape, and the first shell 251 mainly serves as the outer appearance of the compartment 200 of the pet toilet device. The first mounting cavity 248 is mainly defined by the second shell 252, that is, the entire compartment 204 is covered by the second shell 252.

[0037] Continue to refer to Figure 1 as well as Figure 3The housing 203 may also include a cover plate 273, which is detachable from other parts of the housing 203, such as the first housing 251 and / or the second housing 252. The cover plate 273 may be annular, disposed on one side of the first mounting cavity 248 in the housing 203, and completely surrounds and covers the edge of the first inlet / outlet 206. That is, the cover plate 273 partially covers the upper edge of the housing 203 near the first inlet / outlet 206. The cover plate 273 can be connected to the first housing 251 and / or the second housing 252 by various connection methods such as threaded connection and snap-fit ​​connection. By providing this detachable cover plate 273, it is easy to maintain components installed in the second mounting cavity 253, such as the air purification system 400.

[0038] A first air vent 274 is formed on the side of the outer casing 203 facing the first mounting cavity 248. The first air vent 274 is positioned opposite the second inlet / outlet 202. The first air vent 274 is formed on the upper edge of the outer casing 203 near the first inlet / outlet 206. Multiple first air vents 274 may be present, spaced apart along the width direction of the first inlet / outlet 206. Two first air vents 274 may be present, one on the left side of the upper edge of the first inlet / outlet 206 and the other on the right side. The shape of the first air vent 274 is not particularly limited. For example, the first air vent 274 may be formed on the cover plate 273, and may include multiple first ventilation holes 275, which may be spaced apart in a rectangular or circular array on the cover plate 273. However, this is not a limitation; the first air vent 274 may also be formed in a groove shape or other shapes.

[0039] Continue to refer to Figure 5 As described above, the pet toileting device may further include a base 101, and the housing 200 may be installed on the base 101 of the base 100 as a house. The base 101 may be formed by multiple shells overlapping each other. The housing 200 is integrally mounted on the base 101. A third mounting cavity 106 is formed inside the base 101. The control system (not shown), door 500, etc. of the pet toileting device are housed in the third mounting cavity 106. In addition, a part of the air purification system 400 may also be housed in the third mounting cavity 106.

[0040] The following is a general description of the 400 air purification system.

[0041] Continue to refer to Figure 2 , Figure 4 , Figure 5 as well as Figure 6As described above, the air purification system 400 of the embodiment is at least partially disposed within the housing 203. Specifically, the air purification system 400 of the embodiment may be partially disposed within the housing 203 and partially disposed within the base 100. With the housing 200 mounted on the base 101 of the base 100, the air purification system 400 of the embodiment constitutes a single unit. The suction end is disposed within the first mounting cavity 248 at a position opposite to the second inlet / outlet 202, and the discharge end is connected to the outside of the pet toilet device via the third mounting cavity 106 of the base 100.

[0042] The air purification system 400 includes a first fan 401, an air duct section 420, a filter 404, and a second fan 405. The first fan 401 is positioned opposite a second inlet / outlet 202. The suction end of the air duct section 420 is connected to the first fan 401, and the discharge end connects to the outside of the housing 203. The filter 404 is located within the air duct section 420. The second fan 405 is connected to the discharge end of the air duct section 420, and the discharge end of the air duct section 420 connects to the outside of the housing 203 via the second fan 405. Specifically, the air duct section 420 has a first air duct 402 and a second air duct 403. The first fan 401 and the first air duct 402 are located in the second mounting cavity 253 of the outer casing 203. The second air duct 403, the filter 404 and the second fan 405 are located in the third mounting cavity 106 of the base 100. With the outer casing 203 of the cabin 200 mounted on the base 101 of the base 100, the second air duct 403 and the first air duct 402 are connected to form an air purification system 400 with the suction end located in the cabin 200 and the discharge end located in the base 100.

[0043] The first fan 401 is installed inside the second mounting cavity 253 and faces the first air outlet 274. The first fan 401 can be, for example, a suction-type fan, such as a centrifugal fan or a brushless centrifugal fan. Multiple first fans 401 may be included, each corresponding to a position of a first air outlet 274. For example, if there are two first air outlets 274, there are also two first fans 401. With the cover plate 273 covering the circumferential edge of the first inlet / outlet 206, each first fan 401 is covered by the cover plate 273, and the position of each first fan 401 corresponds to the position of the first air outlet 274 formed on the cover plate 273.

[0044] The first air duct 402 extends from the suction end of the air purification system 400 toward the base 101. The first air duct 402 is installed within the second mounting cavity 253. The suction end of the first air duct 402 is connected to the first fan 401, and the discharge end of the first air duct 402 extends toward the base 101. More specifically, the discharge end of the first air duct 402 extends along the shape of the housing 203 in the middle of the second mounting cavity 253 in the left-right direction, and extends to a position adjacent to the rear of the second mounting cavity 253 and the base 100. When there are multiple first fans 401, the first air duct 402 also has multiple branches 406. For example, when there are two first fans 401, the first air duct 402 also has two branches 406. The suction ends of the two branches 406 are respectively connected to their respective first fans 401, and the discharge ends of the two branches 406 respectively extend to a position adjacent to the rear of the second mounting cavity 253 and the base 100. The first air duct 402 has a confluence portion 407 at the middle of its left-right direction behind the second mounting cavity 253, where the discharge ends of each branch 406 converge. The suction end of the confluence portion 407 is connected to each branch 406, and the discharge end of the confluence portion 407 is open and faces the second air duct 403 located on the base 101, and docks with the second air duct 403. The first air duct 402 may have various known connection structures, such as threaded connections or snap-fit ​​connections, formed at the location of the confluence portion 407.

[0045] The second air duct 403 is formed within the base 101. The second air duct 403 can be integrally formed at the same time as the base 101. Alternatively, the second air duct 403 can be formed as a separate component within the third mounting cavity 106. Or, the second air duct 403 can be formed through the mutual fitting between parts of the base 101's shell. In a specific example, a docking portion 120 of the second air duct 403 is formed at the midpoint of the rear left-right direction of the base 101, and a first grille 121 is formed within the docking portion 120. Furthermore, various known connection structures, such as threaded connections and snap-fit ​​connections, are also formed near the docking portion 120 on the base 101. When the cabin portion 200 is mounted on the base 100, in addition to the outer shell 203 and the base 101 being connected by a connection structure such as a threaded connection, the docking portion 120 and the open suction end of the confluence portion 407 are also docked by a known connection structure.

[0046] In a specific example, the second air duct 403 includes a third housing 408 and a fourth housing 409 disposed within a third mounting cavity 106, the third housing 408 and the fourth housing 409 being mounted vertically to each other. The third housing 408 has a second grille 411 formed thereon, and a first channel 412 formed below the second grille 411, the first channel 412 communicating with the second grille 411. Additionally, the third housing 408 has a first insertion port 413 formed on one side of the first channel 412 (e.g., the left-right side), through which the filter 404 is inserted into the second air duct 403. The fourth housing 409 has a third grille 414 formed thereon, and a second channel 415 formed below the third grille 414, the second channel 415 communicating with the third grille 414. Furthermore, the fourth housing 409 has a connecting port 416 formed on one side of the second channel 415 (e.g., the left-right side), the connecting port 416 communicating with the second channel 415. Furthermore, the connecting port 416 is located on the opposite side of the first insertion port 413. The second fan 405 is mounted on the fourth housing 409 and docks with the connecting port 416 of the fourth housing 409; that is, the second fan 405 docks with the connecting port 416 of the second air duct 403 within the third mounting cavity 106. The type of the second fan 405 is not particularly limited as long as it can effectively exhaust air from the second air duct 403; for example, an axial flow fan can be cited.

[0047] The third housing 408 and the second housing 409 of the second air duct 403 are respectively connected to the base 101. In the interconnected state, the first grille 121 is located above the second grille 411, and the second grille 411 is located above the third grille 414. Additionally, a second insertion port 122 is formed on the rear side of the base 101. The second insertion port 122 can be formed in the base 101 and communicates with the third mounting cavity 106. Furthermore, the second insertion port 122 also communicates with the first insertion port 413. Furthermore, the third mounting cavity 106 has a second air vent 123 communicating with the outside. The second air vent 123 can be formed on the rear side of the base 101. The second air vent 123 may include multiple second ventilation holes (not labeled in the drawings), which can be spaced apart in a rectangular or circular array on the rear side of the base 101. The second air vent 123 is connected to the discharge end of the second fan 405.

[0048] The filter 404 is located in the second air duct 403, specifically in the first channel 412 of the second air duct 403. The filter 404 enters the third mounting cavity 106 from the second insertion port 122 of the base 101 and is detachably inserted into the first channel 412 via the first insertion port 413. The filter 404 includes a mounting box 410 and a filter element 417. The mounting box 410 can be pulled out and installed into the base 101 and inserted into the third mounting cavity 106. The filter element 417 can be detachably installed into the mounting box 410. When the mounting box 410 is inserted into the third mounting cavity 106, the filter element 417 is inserted into the second air duct 403. Specifically, the mounting box 410 has a filter element holding part 418 for holding the filter element 417. The form of the filter element holding part 418 is not particularly limited. For example, the filter element holding part 418 can include various forms such as a holding groove or a holding bracket. The filter element 417 can be placed directly in the retaining slot or removed directly from the retaining slot. Furthermore, the mounting box 410 also has a handle 419, which is held by the operator to insert into or remove from the third mounting cavity 106 via the first insertion port 413. The type of filter element 417 in the filter 404 is not particularly limited; any filter element 417 with odor adsorption function is acceptable, such as activated carbon filters including coconut shell, coal, or wood-based activated carbon.

[0049] Thus, the air purification system 400 of this embodiment is entirely built into the housing 203 and the base 100. The suction end of the first air outlet 274 of the air purification system 400 is directly opposite the second inlet / outlet 202 of the chamber 204. Furthermore, even when the chamber 204 rotates to clean up clumps of particulate matter, the first air outlet 274 is always opposite the second inlet / outlet 202. Odor-containing air drawn in by the multiple first fans 401 flows from the first air outlet 274 near the first inlet / outlet 206 of the housing 203, through the branch 406 of the first air duct 402, and converges at the confluence 407 of the first air duct 402. Then, this odor-containing air enters the second air duct 403, which is connected to the first air duct 402 and is disposed in the base 100. When this odor-containing air passes through the filter 404 located in the second air duct 403, the odor is filtered out in the filter 404. Then, the second fan 405, located at the exhaust end of the air purification system 400, discharges the air, which has been filtered by the filter 404 to remove odors, through the second air duct 403 and the second air outlet 123. This completes the removal of odors from the toilet space 201.

[0050] In conventional pet toileting devices, since the chamber 204 is rotatably supported on the base 100, the air vent is typically positioned at the center of rotation of the chamber 204 (i.e., the support shaft 227) to ensure proper connection between the air purification system 400 and the rotating chamber 204. This results in limited space for the air vent, leading to lower efficiency of the air purification system 400. Furthermore, odors easily escape from the inlet and outlet of the chamber 204, potentially causing odors to accumulate near the inlet and outlet of the pet toileting device. In the pet toileting device of this embodiment, by providing a housing 203 enclosing the chamber 204, the chamber 204 can rotate within the first mounting cavity 248 of the housing 203, reducing the portion of the chamber 204 exposed to the outside. Moreover, by providing the housing 203, the air purification system 400 can be independently configured within the housing 203, increasing the configuration flexibility and purification efficiency of the air purification system 400.

[0051] Specifically, by positioning the suction end of the air purification system 400 opposite the second inlet / outlet 202 of the compartment 204, the area covered by the suction end of the air purification system 400 can be greatly expanded, thereby improving the purification efficiency of the air purification system 400. This improves the purification efficiency of the air in the toilet space 201 within the compartment 204. Furthermore, because the suction end of the air purification system 400 is positioned opposite the second inlet / outlet 202 of the compartment 204, the diffusion of odors from the compartment 204 from the second inlet / outlet 202 to the outside of the pet toilet device can be suppressed.

[0052] In the pet toileting device of the embodiment, the air purification system 400 includes a filter 404 located in the air duct 420, so that odors can be effectively filtered before being discharged to the outside of the housing 203.

[0053] Furthermore, the air purification system 400 includes a second fan 405 connected to the exhaust end of the duct section 420, which, combined with the first fan 401 connected to the suction end of the duct section 420, enhances the overall convection capacity of the air purification system 400, thereby improving purification efficiency. For example, in the embodiment of the air purification system 400, the first fan 401 uses an intake fan, while the second fan 405 uses an exhaust fan, which significantly improves the convection capacity of the air purification system 400 within the duct section 420.

[0054] Furthermore, by providing a second fan 405, even if the length of the duct section 420 is long or the duct section 420 has other branches, the convection capacity within the duct section 420 can be ensured, thereby improving the purification efficiency.

[0055] In the pet toileting device of the embodiment, the outer casing 203 has a hollow layer 272, and a second mounting cavity 253 is formed within the hollow layer 272, which allows components of the air purification system 400 to be easily housed within the second mounting cavity 253. For example, by housing components such as the first fan 401 of the air purification system 400 within the second mounting cavity 253, it is possible to prevent them from attracting the attention of pets and being damaged by them.

[0056] Furthermore, the odor-containing air in the toilet space 201 will escape upwards towards the second inlet / outlet 202. By positioning the first air vent 274 of the air purification system 400 near the upper edge of the outer casing 203 close to the first inlet / outlet 206, the first air vent 274 can more efficiently draw in this odor-containing air, thereby improving the purification efficiency of the air purification system 400. Moreover, since the upper edge of the outer casing 203 near the first inlet / outlet 206 extends above the first inlet / outlet 206, it can further efficiently draw in this odor-containing air.

[0057] Furthermore, since the upper edge of the outer shell 203 near the first inlet / outlet 206 always coincides with the toilet space 201 of the compartment 204, placing the first air vent 274 at this position can always keep the air purification system 400 in working condition, thereby further improving the purification efficiency of the air purification system 400.

[0058] Moreover, by configuring the first air vent 274 at this location, the range that the first air vent 274 can cover can be expanded. For example, by configuring multiple first air vents 274 that are spaced apart along the width direction of the first inlet and outlet 206, the first air vent 274 can span a larger area along the width direction of the second inlet and outlet 202 of the toilet space 201, which can further improve the purification efficiency of the air purification system 400.

[0059] In the pet toileting device of the embodiment, the air purification system 400 can be easily maintained by providing a removable cover 273 on the upper edge of the cover housing 203 near the first inlet / outlet 206. For example, by removing the cover 273, the first fan 401 covered by the cover 273 can be easily maintained. In addition, by removing the cover 273, the cover 273 can be cleaned, preventing blockages such as clogging of the first air vent 274 formed on the cover 273.

[0060] In the pet toileting device of this embodiment, by placing the exhaust end of the air purification system 400 within the third mounting cavity 106 located at the base 100, other components of the air purification system 400 can be easily configured. For example, since the base 100 has sufficient mounting space, the filter 404 of the air purification system 400 can be easily configured within the third mounting cavity 106 of the base 100 without needing to consider the size or installation method of the filter 404. That is, the exhaust end of the air duct 420 of the air purification system 400 is connected to the outside of the housing 203 via the base 100.

[0061] In addition, the filter 404 includes a mounting box 410 and a filter element 417, and the mounting box 410 can be detachably installed on the base 101, thereby making it very convenient to replace the filter element 417.

[0062] In the pet toileting device of the embodiment, the air purification system 400 includes a first air duct 402 formed in the housing 203 and a second air duct 403 formed in the base 101. With the housing 203 set on the base 101, the second air duct 403 and the first air duct 402 are connected. Thus, the air duct of the air purification system 400 can be easily configured as a whole without the need for other connecting structures.

[0063] Furthermore, the first air duct 402 has multiple branches 406 and a confluence 407, which can cover the area that the first air outlet 274 can cover, while allowing the first air duct 402 and the second air duct 403 to connect at only one point. Therefore, the difficulty of connection can be reduced, and the overall airtightness of the air duct section 420 can be improved.

[0064] Additionally, it should be noted that while the above-described pet toileting device includes an example of an air purification system 400 including a second fan 405, it is not limited to this. If the length of the air duct 420 is relatively short, the second fan 405 may not be required.

[0065] For example, the air purification system 400 may mainly include a first fan 401, a first air duct 402 of the air duct section 420, and a filter 404. The first fan 401, the first air duct 402, and the filter 404 are respectively disposed in the second mounting cavity 253. The first air outlet 274 is formed on the side of the housing 203 facing the first mounting cavity 248 as described above, while the second air outlet 123 is formed on the outer side of the housing 203 opposite to the first air outlet 274. In this way, the length of the air duct section 420 can be shortened, so that even without the second fan 405, odors in the toilet space can be effectively purified. In addition, in this embodiment, the first fan 401 may also be selected as a bidirectional axial flow fan or the like, which has both intake and exhaust functions.

[0066] Additionally, it should be noted that while the above-described pet toileting device illustrates an example where the outer casing 203 has a hollow layer 272 and a portion of the air purification system 400 is disposed in the second mounting cavity 253 within this hollow layer 272, it is not limited to this. The outer casing 203 may also lack this hollow layer 272; that is, the outer casing 203 may not have the second casing 252. In this case, the first fan 401 and the first air duct 402 of the air purification system 400 can be installed on one side of the outer casing 203 located in the first mounting cavity 248, and the first fan 401 can be positioned opposite the second inlet / outlet 202.

[0067] Furthermore, in this embodiment, a cover plate 273 can be provided for each of the multiple first fans 401 of the air purification system 400, and a first air vent 274 can be formed on the cover plate 273.

[0068] In the pet toileting device described in the above embodiment, although an example has been given in which the suction end of the air purification system 400 is disposed in the outer casing 203 and the discharge end is disposed in the base 100, the invention is not limited thereto. For example, the discharge end of the air purification system 400 may also be disposed in the hollow layer 272 of the outer casing 203, for example, it may be disposed on one or both sides of the rear side in the left-right direction of the hollow layer 272 of the outer casing 203. That is, the air duct portion 420 of the air purification system 400 may be connected to the outside of the outer casing 203 without passing through the base 100.

[0069] In addition, in this method, the second air duct 403 may be omitted, and the second fan 405 may be directly connected to the exhaust end of the first air duct 402.

[0070] Furthermore, although an example of a first air duct 402 having a branch section 406 and a confluence section 407 has been described, it is not limited to this. For example, in this manner, each first fan 401 may correspond to one first air duct 402, meaning that multiple first air ducts 402 may be provided. Each first air duct 402 has a first fan 401 and a second fan 405 respectively arranged at both ends.

[0071] It should be noted that although the pet toileting device is divided into a base 100 and a housing 200 for ease of explanation, the base 100 and the housing 200 can be assembled together to form the pet toileting device, or they can be originally one piece. For example, although an example is given where the base 100 includes a base 101 and the housing 200 includes a housing 203, the base 101 and the housing 203 can also be integrally formed components. That is, the pet toileting device of the embodiment can include a single housing, with a portion of the housing serving as the base 101 to support the main body 204, and a portion serving as the housing 203 to enclose the main body 204.

[0072] Although embodiments of this implementation have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this implementation, the scope of which is defined by the claims and their equivalents.
