Description

Technical Field

[0001] This utility model relates to the field of air purification technology, specifically to a pet air purifier. Background Technology

[0002] Currently available pet air purifiers primarily function to remove pet odors and floating pollutants such as pet hair and dander that have already spread into the home environment. They passively treat these pollutants through adsorption and filtration, thereby improving overall indoor air quality. However, this passive approach cannot effectively prevent the continuous accumulation of pollution caused by pets themselves as a source of contamination. Odors and floating pollutants continue to be generated and diffuse into the environment, resulting in low purification efficiency. Utility Model Content

[0003] In view of this, the present invention provides a pet air purifier to solve the problem of low purification efficiency caused by the inability to effectively block the continuous accumulation of pollution caused by pets themselves as a source of pollution, the continuous generation of odors and floating pollutants and their spread to the environment.

[0004] This utility model provides a pet air purifier, comprising:

[0005] The main body of the air purifier has a first air inlet and a first air outlet;

[0006] The purification air duct is located inside the main body of the purifier;

[0007] The pet compartment is located inside the main body of the purifier and has a second air inlet and a second air outlet. The pet compartment is used to accommodate a pet.

[0008] The gas inside the pet compartment flows sequentially through the second air outlet, the purification duct, and the second air inlet back to the pet compartment, forming an internal circulation path; the gas inside the pet compartment flows sequentially through the second air outlet, the purification duct, and the first air outlet to be discharged to the outside, forming a first external circulation path; the gas outside the purifier body flows sequentially through the first air inlet, the purification duct, and the first air outlet to be discharged to the outside, forming a second external circulation path.

[0009] Beneficial effects: The internal circulation path continuously purifies the air inside the pet compartment by passing through the purification duct before returning it to the compartment, achieving localized deep purification of the air inside the pet compartment. It can specifically remove odors and loose hair carried by the pet, improving purification efficiency from the source and reducing the pollution left in the indoor environment after the pet leaves. The first external circulation path can exhaust the purified air inside the pet compartment to the outside, achieving targeted discharge of polluted gas and preventing the accumulation of polluted air inside the pet compartment. The second external circulation path can draw in air from outside the purifier body, purify it, and then discharge it, achieving active cleaning of the external air. The three working together improve purification efficiency, resulting in better air purification effect, effectively purifying the overall indoor air and improving the air quality of the home environment.

[0010] In one alternative embodiment, a pet attractor is also included, wherein the pet compartment has a pet entrance, and the pet attractor is disposed on the purifier body near the pet entrance.

[0011] Beneficial effects: The pet attractant can effectively attract pets to actively approach and enter the pet compartment, increasing the pets' enthusiasm and frequency of entering the pet compartment, so that the pet purifier can more fully purify the pets and the odors and hair they carry, thereby enhancing the overall purification effect.

[0012] In one optional embodiment, the pet entrance is provided with a hatch; the purifier body further includes:

[0013] A sensor is positioned facing the second air outlet to collect a signal indicating that a pet has entered the air outlet.

[0014] The control board is communicatively connected to both the sensing device and the hatch, and is used to acquire the pet entry signal and control the hatch to close based on the pet entry signal.

[0015] Beneficial effects: When the sensor detects a pet entering and transmits the signal to the control board, the control board promptly instructs the door to close, effectively confining the pet inside the enclosure and preventing it from leaving during the purification process. This ensures the purification operation is fully effective for the pet, improving the thoroughness of the purification process. Simultaneously, the closed door reduces the exchange between purified air and unpurified air, maintaining a stable purification environment and guaranteeing purification efficiency. Furthermore, the automatic closing design eliminates the need for manual intervention, saving users time and effort and preventing ineffective purification due to forgetting to close the door. This further enhances convenience and reliability, providing users with greater peace of mind.

[0016] In an alternative implementation, a pet interaction element is also included, disposed inside the pet cabin.

[0017] Beneficial effects: By incorporating interactive elements, pets' attention is effectively attracted, encouraging them to stay inside the pet enclosure and interact with the elements, reducing the likelihood of them running around or attempting to leave. By keeping pets more stable within the purification area, the pet purifier can continuously and thoroughly purify them, avoiding incomplete purification caused by frequent pet movement, ensuring purification stability, and improving purification effectiveness.

[0018] In one optional implementation, the purification duct includes:

[0019] The airflow channel is connected to the first air inlet, the first air outlet, the second air inlet, and the second air outlet;

[0020] The purification component is installed within the airflow channel.

[0021] Beneficial effects: The airflow channel is connected to the first air inlet, first air outlet, second air inlet, and second air outlet, allowing air from the pet compartment and surrounding environment to enter and exit the airflow channel in an orderly manner through different vents, ensuring comprehensive and smooth air circulation. The purification components installed within the airflow channel effectively purify the air flowing through it, whether it's air drawn from the pet compartment containing odors or pet hair, or air introduced from the outside requiring purification. This achieves both efficient air circulation and thorough purification, thereby improving the overall purification effect.

[0022] In one optional embodiment, the purification element is a filter screen, and at least one of the filter screens is provided between the second air outlet and the second air inlet; and / or, at least one of the filter screens is provided between the second air outlet and the first air outlet; and / or, at least one of the filter screens is provided between the first air inlet and the first air outlet.

[0023] Beneficial effects: By installing a filter between the second air outlet and the second air inlet, effective purification of the airflow in the internal circulation path is ensured; by installing a filter between the second air outlet and the first air outlet, effective purification of the airflow in the first external circulation path is ensured; by installing a filter between the first air inlet and the first air outlet, effective purification of the airflow in the second external circulation path is ensured.

[0024] In one alternative embodiment, the filter screen includes a physical adsorption layer and a chemical decomposition layer, wherein the physical adsorption layer is disposed upstream of the chemical decomposition layer.

[0025] Beneficial Effects: When airflow first passes through the physical adsorption layer, the layer utilizes its porous structure or adsorption properties to efficiently intercept solid pollutants such as particulate matter, hair, and dust, as well as some large-molecule odor substances, playing a preliminary purification and pretreatment role. This not only directly reduces the concentration of pollutants in the air but also prevents the subsequent chemical decomposition layer from being covered or blocked by a large number of solid impurities, ensuring its continuous and stable operation and extending the overall lifespan of the filter. The pre-purified airflow then enters the chemical decomposition layer, which chemically decomposes or neutralizes small-molecule harmful gases and residual odors that are difficult for the physical adsorption layer to handle, converting them into harmless substances and fundamentally eliminating pollutants. Through the synergistic effect of interception followed by decomposition, the filter can efficiently handle various types of pollutants while preventing the re-release of adsorbed pollutants and secondary pollution, thus improving the thoroughness and safety of air purification.

[0026] In one alternative embodiment, the purification duct further includes a fan disposed within the airflow channel.

[0027] Beneficial effects: A fan installed within the airflow channel provides power, accelerating airflow circulation. This allows air from the pet enclosure and surrounding environment to enter the airflow channel more quickly through the first and second air inlets, be processed by the purification components, and then exit through the first and second air outlets. This not only improves air circulation efficiency and shortens the air purification cycle but also allows more air to enter the airflow channel and flow through the purification components, ensuring more thorough and comprehensive purification and avoiding incomplete purification in certain areas due to slow airflow. Furthermore, the fan ensures timely diffusion of purified air, resulting in a more efficient overall purification effect.

[0028] In one alternative embodiment, a single-sided air inlet valve is provided at the second air inlet.

[0029] Beneficial effects: By setting a single-sided air inlet valve, one-way control of airflow is achieved, allowing only external air to enter the pet cabin through the second air inlet, while completely blocking the possibility of internal air flowing out to the outside through this path; since reverse exhaust is not possible, odors generated by the pet's activities inside the pet cabin are locked inside the pet cabin, ensuring that the air inside the pet cabin can only be exhausted through the second air outlet, and will not flow through the second air inlet and be blown out directly from the first air outlet, thus avoiding odor pollution to the external environment.

[0030] In one optional embodiment, the purifier body further includes an air outlet channel, and the top of the purifier body is provided with a top air outlet. The two ends of the air outlet channel are respectively connected to the first air outlet and the top air outlet. The airflow from the first air outlet flows through the air outlet channel and the top air outlet in sequence and is discharged to the outside.

[0031] Beneficial effects: By setting up an air outlet duct connecting the first air outlet and the top air outlet, a clear and smooth exhaust path is provided for the purified airflow. The top air outlet allows the purified air to be blown upwards from a higher position, covering a wider area, accelerating the diffusion of clean air in the space, promoting air circulation throughout the room, and preventing clean air from accumulating only near the pet air purifier, thereby improving the overall air purification and renewal efficiency.

[0032] In one alternative embodiment, the bottom of the pet compartment is provided with a litter box.

[0033] Beneficial effects: Installing a litter box under the pet compartment ensures the convenience of the pet's toilet use during the purification process, while also concentrating excrement in the litter box to prevent it from scattering in other areas of the pet compartment. Because the excrement can enter the litter box in a timely manner, the possibility of it remaining inside the pet compartment and breeding bacteria is reduced, which helps maintain a good environment inside the compartment and reduces the workload and difficulty of cleaning the pet compartment.

[0034] In one alternative embodiment, the litter box includes:

[0035] The tank is located at the bottom of the pet compartment.

[0036] The cat litter separation component is located at the bottom of the tank and has a support position for supporting the cat litter and a separation position for separating the cat litter.

[0037] Beneficial effects: The litter box provides a stable container for cat litter, and because it is located at the bottom of the pet compartment, it can effectively collect pet excrement, preventing it from spilling and polluting the surrounding environment. It also provides a centralized area for subsequent cleaning. When in the support position, the litter separator firmly supports the litter, ensuring it functions properly when the pet uses the litter box. When switched to the separation position, it separates the litter from excrement, allowing users to quickly remove excrement without laborious sifting, simplifying the cleaning process and reducing cleaning time and workload. Furthermore, the separation function maximizes the retention of usable litter, avoiding unnecessary waste and reducing pet ownership costs.

[0038] In one optional implementation, the litter separation component includes:

[0039] Separation holes are provided on the bottom wall of the tank;

[0040] A telescopic baffle is installed above the bottom wall of the tank, having a supporting position to block the separation hole and a separation position to open the separation hole for cat litter separation.

[0041] Beneficial effects: The separation hole serves as a channel for separating cat litter from excrement. When separation is needed, clean cat litter of the correct size falls through the separation hole, while excrement remains on top, achieving rapid separation. When the telescopic baffle is in the support position, it covers the separation hole, ensuring the cat litter is stably supported within the container and does not interfere with the pet's normal elimination process. When cleaning is required, simply switch the telescopic baffle to the separation position, and the separation hole opens, allowing clean cat litter to pass through smoothly, while the remaining excrement is easily collected and cleaned. The switching operation of the telescopic baffle is simple and convenient, requiring no complicated steps, reducing cleaning difficulty and saving cleaning time.

[0042] In one optional embodiment, the litter box is provided in two sets, which are stacked vertically and connected through the separation hole; and both sets of litter boxes can be detachably installed at the bottom of the pet compartment.

[0043] Beneficial effects: By stacking two litter troughs vertically, when the telescopic baffle of the upper litter trough is in the separated position, clean litter filtered through the separation hole can fall directly into the lower litter trough, achieving automatic transfer and recycling of litter. This eliminates the need for manual collection and handling, reducing litter waste and simplifying operation, making litter recycling more efficient and convenient. Furthermore, since both litter troughs are detachable, when cleaning the upper litter trough, it can be removed, and the lower litter trough containing clean litter can be moved to the upper one for the pet to use, ensuring uninterrupted toileting. After cleaning, the upper litter trough can be reinstalled to continue collecting clean litter falling from above, achieving recycling. This flexible, detachable switching method ensures convenient and efficient cleaning while allowing the two litter troughs to operate alternately, reducing interruptions caused by cleaning and making pet care easier.

[0061] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0062] The following is combined with Figures 1 to 7 The following describes embodiments of the present invention.

[0063] According to an embodiment of the present invention, a pet air purifier is provided, including a purifier body 10, a purification duct, and a pet housing 30; the purifier body 10 is provided with a first air inlet 11 and a first air outlet 12; the purification duct is disposed inside the purifier body 10; the pet housing 30 is disposed inside the purifier body 10, and is provided with a second air inlet 31 and a second air outlet 32, and the pet housing 30 is used to accommodate a pet; wherein, the gas inside the pet housing 30 flows sequentially through the second air outlet 32, the purification duct, and the second air inlet 31 and returns to the pet housing 30 to form an internal circulation path; the gas inside the pet housing 30 flows sequentially through the second air outlet 32, the purification duct, and the first air outlet 12 and is discharged to the outside to form a first external circulation path; the gas outside the purifier body 10 flows sequentially through the first air inlet 11, the purification duct, and the first air outlet 12 and is discharged to the outside to form a second external circulation path.

[0064] In the above embodiments, the internal circulation path allows the air inside the pet cabin 30 to continuously flow through the purification duct and return to the cabin after purification, achieving localized deep purification of the air inside the pet cabin 30. This can specifically remove odors and loose hair carried by the pet, improving purification efficiency from the source and reducing the pollution left in the indoor environment after the pet leaves. The first external circulation path can exhaust the purified gas inside the pet cabin 30 to the outside, achieving directional discharge of polluted gas and preventing the accumulation of polluted air inside the pet cabin 30. The second external circulation path can draw in air from outside the purifier body 10, purify it, and then discharge it, achieving active cleaning of the external ambient air. The three work together to improve purification efficiency, resulting in better air purification and effectively purifying the overall indoor air, thus improving the air quality of the home environment.

[0065] Specifically, a first air inlet grille is provided at the first air inlet 11, and a first air outlet grille is provided at the first air outlet 12; a second air inlet grille is provided at the second air inlet 31, and a second air outlet grille is provided at the second air outlet 32. Each air inlet and outlet is equipped with a dedicated grille, which not only ensures the smooth flow of air, but also achieves preliminary filtration and guidance of the airflow entering the equipment through the grille structure, while optimizing the uniformity of airflow and protecting the internal components.

[0066] Specifically, a first air inlet 11 is provided on the lower side of each of the opposite side walls of the purifier body 10 to draw in high-density pollutants accumulated at the bottom; a second air outlet 32 ​​is provided on each of the opposite side walls of the pet compartment 30 to form bidirectional convection to accelerate the discharge of polluted gas in the compartment; a second air inlet 31 is provided on the top of the pet compartment 30 and is located below the first air outlet 12.

[0067] In one embodiment, a pet attractor 40 is also included, and a pet entrance 33 is provided on the pet housing 30. The pet attractor 40 is disposed on the purifier body 10 near the pet entrance 33.

[0068] In the above embodiments, the pet attractant 40 can effectively attract pets to actively approach and enter the pet cabin 30, increasing the pet's enthusiasm and frequency of entering the pet cabin 30, so that the pet purifier can more fully purify the pet and the odors, hair, etc. it carries, thereby enhancing the overall purification effect.

[0069] Specifically, the pet attractor 40 can attract pets by releasing scents or making sounds, including but not limited to scent-emitting devices such as mint balls, sound-producing devices such as bells, or toys such as cat teasers; in this embodiment, the pet attractor 40 is preferably a toy such as a cat teaser.

[0070] In one embodiment, a hatch is provided at the pet entrance 33; a sensor 13 and a control board are provided on the purifier body 10; the sensor 13 is positioned facing the second air outlet 32 ​​and collects the pet entry signal through the second air outlet 32; the control board is communicatively connected to both the sensor 13 and the hatch, and is used to obtain the pet entry signal from the sensor 13 and control the closing of the hatch according to the pet entry signal.

[0071] In the above embodiment, when the sensor 13 detects a pet entering and transmits the signal to the control board, the control board can promptly instruct the door to close. This effectively confines the pet within the pet enclosure 30, preventing it from leaving during the purification process and ensuring that the purification operation is fully effective for the pet, thus improving the thoroughness of the purification. Simultaneously, closing the door reduces the exchange between purified air inside the enclosure and unpurified air outside, maintaining the stability of the purified environment and ensuring purification efficiency. Furthermore, the automatic closing design eliminates the need for manual intervention, saving users time and effort and preventing poor purification results due to forgetting to close the door. This further enhances the convenience and reliability of use, making it more worry-free for users.

[0072] Specifically, a hatch is provided at the pet entrance 33 to open or close the pet entrance 33, so as to enable the pet to enter and exit and the pet cabin 30 to be closed.

[0073] Specifically, the sensing device 13 is an infrared sensor. When a pet enters the pet enclosure 30, the infrared light emitted by the infrared sensor is blocked and reflected by the pet. The infrared sensor detects the presence of the pet by identifying changes in the reflected signal, and then generates a corresponding pet entry signal.

[0074] Specifically, the main body 10 of the purifier is provided with an operation display panel 16, which serves as the operation and display area for the entire pet purifier.

[0075] Specifically, the main body 10 of the purifier is equipped with an odor monitoring module that can sense changes in odor concentration.

[0076] In a specific implementation, when the pet enters the pet compartment 30 and the compartment door is closed, the operation display panel 16 on the main body 10 of the purifier shows that the quick purification mode is turned on. The user can choose to actively click the panel to turn off the quick purification mode, thereby unlocking and opening the compartment door; or, wait for the purification system to continue running. During operation, the built-in odor monitoring module will monitor the environment inside the compartment in real time. Once the concentration of floating hair and odor drops below the preset threshold, it indicates that the purification is complete, and the system will automatically unlock and open the compartment door to allow the pet to leave safely.

[0077] In one embodiment, a pet interaction component is also included, disposed inside the pet housing 30.

[0078] In the above embodiments, the pet interactive elements effectively attract the pet's attention, making the pet more willing to stay inside the pet cabin 30 to interact and play with the interactive elements, reducing the likelihood of the pet running around inside or even trying to leave. By keeping the pet more stably within the purification area, the pet purifier can continuously and thoroughly purify the pet, avoiding incomplete purification caused by frequent pet movement, ensuring the stability of the purification process, and improving the purification effect.

[0079] Specifically, pet interactive components include, but are not limited to, sound-producing devices such as bells or toys such as cat wands and scratching posts; in this embodiment, the preferred pet attractant 40 is a scratching post, which is fixed to the inner wall of the pet compartment 30.

[0080] In one embodiment, the purification duct includes an airflow channel 21 and a purification component 22; the airflow channel 21 is connected to the first air inlet 11, the first air outlet 12, the second air inlet 31 and the second air outlet 32; the purification component 22 is disposed within the airflow channel 21.

[0081] In the above embodiment, the airflow channel 21 is connected to the first air inlet 11, the first air outlet 12, the second air inlet 31, and the second air outlet 32, allowing air from the pet cabin 30 and its surrounding environment to enter and exit the airflow channel 21 in an orderly manner through different air outlets, ensuring comprehensive and smooth air circulation. The purification component 22 installed in the airflow channel 21 can purify the air flowing through the channel, effectively purifying both odorous and hairy air drawn from the pet cabin 30 and air to be purified introduced from the outside. This achieves both efficient air circulation and thorough purification, thereby improving the overall purification effect.

[0082] In one embodiment, the purification element 22 is a filter screen, and at least one filter screen is provided between the second air outlet 32 ​​and the second air inlet 31; and / or, at least one filter screen is provided between the second air outlet 32 ​​and the first air outlet 12; and / or, at least one filter screen is provided between the first air inlet 11 and the first air outlet 12.

[0083] In the above embodiments, by setting a filter between the second air outlet 32 ​​and the second air inlet 31, effective purification of the airflow in the internal circulation path is ensured; by setting a filter between the second air outlet 32 ​​and the first air outlet 12, effective purification of the airflow in the first external circulation path is ensured; and by setting a filter between the first air inlet 11 and the first air outlet 12, effective purification of the airflow in the second external circulation path is ensured.

[0084] In one embodiment, the filter screen includes a physical adsorption layer and a chemical decomposition layer, with the physical adsorption layer disposed upstream of the chemical decomposition layer.

[0085] In the above embodiments, when the airflow first passes through the physical adsorption layer, the physical adsorption layer can utilize its porous structure or adsorption characteristics to efficiently intercept solid pollutants such as particulate matter, hair, and dust in the air, as well as some large molecular odor substances, playing a preliminary purification and pretreatment role. This not only directly reduces the concentration of pollutants in the air but also prevents the subsequent chemical decomposition layer from being covered or blocked by a large number of solid impurities, ensuring its continuous and stable working state and extending the overall service life of the filter. The airflow that has undergone preliminary purification enters the chemical decomposition layer, which can chemically decompose or neutralize small molecule harmful gases and residual odors that are difficult for the physical adsorption layer to handle, converting them into harmless substances and fundamentally eliminating pollutants. Through the synergistic effect of interception followed by decomposition, the filter can not only efficiently handle various types of pollutants but also prevent the re-release of adsorbed pollutants, thus avoiding secondary pollution and improving the thoroughness and safety of air purification.

[0086] Specifically, the physical adsorption layer includes a pre-filtration unit and a HEPA (High-Efficiency Particulate Air) filter unit; the pre-filtration unit is used to intercept larger pollutants in the air, including but not limited to hair, dust, etc.; the HEPA filter unit is used to intercept ultrafine particulate matter in the air, such as pet dander, etc.

[0087] Specifically, the chemical decomposition layer uses a modified activated carbon layer to adsorb and decompose NH3 (ammonia) and H2S (hydrogen sulfide) gases. A 20nm TiO2 photocatalyst and Bacillus subtilis bio-enzymes are loaded onto the activated carbon support, working in conjunction with the physical adsorption layer to achieve a triple purification mechanism of physical adsorption, photochemical decomposition, and biodegradation. Since the activity of bio-enzymes generally does not survive for long, Bacillus subtilis is immobilized using sodium alginate microcapsule technology, achieving a survival rate greater than or equal to 95%. To enhance the catalytic effect of TiO2, a TiO2 layer is deposited on the activated carbon surface using a sol-gel method, resulting in a higher concentration of TiO2 on the activated carbon surface. Under UV (ultraviolet) excitation, TiO2 generates -OH (hydroxyl) free radicals, oxidizing NH3 to NO3-. Subsequently, Bacillus subtilis secretes urease, converting the remaining NH3 into harmless N2 (nitrogen gas).

[0088] In one embodiment, the purification duct further includes a fan 23, which is disposed within the airflow channel 21.

[0089] In the above embodiment, a fan 23 is installed in the airflow channel 21. The fan 23 provides power to accelerate the airflow circulation speed in the channel, allowing the air from the pet cabin 30 and the surrounding environment to enter the airflow channel 21 more quickly through the first air inlet 11 and the second air inlet 31. After being processed by the purification component 22, the air is then discharged from the first air outlet 12 and the second air outlet 32. This not only improves the efficiency of air circulation and shortens the air purification cycle, but also allows more air to enter the airflow channel 21 and flow through the purification component 22, ensuring more thorough and comprehensive purification and avoiding the problem of incomplete local purification caused by slow airflow. Furthermore, the fan 23 also allows the purified clean air to diffuse in a timely manner, making the overall purification effect more efficient.

[0090] In one embodiment, a single-sided air inlet valve is provided at the second air inlet 31.

[0091] In the above embodiment, by setting a single-sided air inlet valve, unidirectional control of airflow is achieved, allowing only external air to enter the pet cabin 30 through the second air inlet 31, while completely blocking the possibility of internal air flowing out to the outside through this path. Since reverse exhaust is not possible, the odor generated by the pet's activities inside the pet cabin 30 is locked inside the pet cabin 30, ensuring that the air inside the pet cabin 30 can only be discharged through the second air outlet 32, and will not flow through the second air inlet 31 and be blown out directly from the first air outlet 12, thus avoiding the pollution of the external environment by the odor.

[0092] In one embodiment, the purifier body 10 further includes an air outlet 14, and the top of the purifier body 10 is provided with a top air outlet 15. The two ends of the air outlet 14 are respectively connected to the first air outlet 12 and the top air outlet 15. The airflow from the first air outlet 12 flows through the air outlet 14 and the top air outlet 15 in sequence and is discharged to the outside.

[0093] In the above embodiment, by providing an air outlet duct 14 connecting the first air outlet 12 and the top air outlet 15, a clear and smooth exhaust path is provided for the purified airflow. The top air outlet 15 allows the purified air to be blown upwards from a higher position, covering a wider area, accelerating the diffusion speed of clean air in the space, promoting air circulation throughout the room, and preventing clean air from accumulating only near the pet air purifier, thereby improving the overall air purification and renewal efficiency.

[0094] Specifically, a top air outlet grille is provided at the top air outlet 15.

[0095] In one embodiment, the bottom of the pet compartment 30 is provided with a litter box 50.

[0096] In the above embodiment, a litter box 50 is provided below the pet compartment 30. During the purification process, this ensures the convenience of the pet's toilet use and concentrates the excrement in the litter box 50, preventing the excrement from scattering in other areas of the pet compartment 30. Since the excrement can enter the litter box 50 in a timely manner, the possibility of it remaining and breeding bacteria inside the pet compartment 30 is reduced, which helps to maintain a good environment inside the compartment and reduces the workload and difficulty of cleaning the pet compartment 30.

[0097] In one embodiment, the litter box 50 includes a box body 51 and a litter separation component; the box body 51 is disposed at the bottom of the pet compartment 30; the litter separation component is disposed at the bottom of the box body 51 and has a support position for supporting the litter and a separation position for separating the litter.

[0098] In the above embodiment, the trough 51 provides a stable space for cat litter, and because it is located at the bottom of the pet compartment 30, it can smoothly receive pet excrement, preventing it from leaking and polluting the surrounding environment. It also provides a centralized operating area for subsequent cleaning. When in the support position, the cat litter separation component firmly supports the cat litter, ensuring it functions properly when the pet uses the toilet. When switched to the separation position, it separates the cat litter from the excrement, allowing users to quickly remove the excrement without laborious sifting, simplifying the cleaning process and reducing cleaning time and workload. Furthermore, the separation function maximizes the retention of usable cat litter, avoiding unnecessary waste and reducing pet ownership costs.

[0099] In one embodiment, the cat litter separation assembly includes a separation hole 521 and a telescopic baffle 522; the separation hole 521 is disposed on the bottom wall of the tank 51; the telescopic baffle 522 is disposed above the bottom wall of the tank 51, having a support position for blocking the separation hole 521 and a separation position for opening the separation hole 521 to allow cat litter separation.

[0100] In the above embodiment, the separation hole 521 serves as a channel for separating cat litter and excrement. When separation is needed, clean cat litter of the appropriate size can fall through the separation hole 521, while excrement remains above, achieving rapid separation. When the telescopic baffle 522 is in the support position, it can block the separation hole 521, ensuring that the cat litter is stably supported within the trough 51 and does not affect the pet's normal excretion. When cleaning is required, simply switch the telescopic baffle 522 to the separation position, and the separation hole 521 will open, allowing clean cat litter to pass smoothly through the separation hole 521, while the remaining excrement is easy to collect and clean. The switching operation of the telescopic baffle 522 is simple and convenient, requiring no complicated steps, reducing cleaning difficulty and saving cleaning time.

[0101] Preferably, a small vibration motor is installed at the bottom or side wall of the tank 51. When the odor monitoring module detects an odor, the control board controls the telescopic baffle 522 to switch to the separation position where the separation hole 521 is opened for cat litter separation. At the same time, the small vibration motor drives the tank 51 to vibrate, causing the clumps in the cat litter to separate from the loose litter, and the fine cat litter is shaken into the cat litter trough 50 located below. When no more cat litter is detected falling into the separation hole 521, it indicates that the cat litter separation is complete, and the control board controls the small vibration motor to stop vibrating.

[0102] In this embodiment, after the cat litter is separated, the cat litter trough 50 is pulled out from the bottom of the pet compartment 30, the remaining excrement in the cat litter trough 50 is poured out, and then the cleaned cat litter trough 50 is put back into the bottom of the pet compartment 30 for reuse.

[0103] In one embodiment, the litter box 50 is provided in two sets, which are stacked vertically and connected through the separation hole 521; and both sets of litter boxes 50 can be detachably installed at the bottom of the pet compartment 30.

[0104] In the above embodiment, two sets of litter troughs 50 are stacked vertically. When the telescopic baffle 522 of the upper litter trough 50 is in the separated position, the clean litter filtered through the separation hole 521 can fall directly into the lower litter trough 50, realizing automatic transfer and recycling of litter. There is no need for manual collection and handling, which reduces litter waste and simplifies operation, making litter recycling more efficient and convenient. Furthermore, since both sets of litter troughs 50 are detachable, when it is necessary to clean the excrement in the upper litter trough 50, it can be removed, and the lower litter trough 50 containing clean litter can be transferred to the upper litter trough for continued use by the pet, ensuring that the pet's toileting is not affected. After the upper litter trough 50 is cleaned, it can be installed back in the lower position to continue receiving clean litter falling from above, realizing recycling. The detachable and flexible switching method not only ensures the convenience and efficiency of the cleaning process, but also realizes the alternating operation of the two sets of litter troughs 50, reducing the problem of interruption of use due to cleaning, making pet care more worry-free.

[0105] Specifically, the bottom of the pet compartment 30 has an installation space, and both sets of litter boxes 50 can be detachably installed in the installation space.

[0106] In a specific implementation, each litter box 50 has a groove on its outer side wall of the box body 51, while a matching slide rail is provided on the inner side wall of the installation space. By pushing the groove on the litter box 50 along the slide rail of the installation space, the litter box 50 can be precisely positioned and securely installed.

[0107] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
