[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0038] like Figures 1 to 5 As shown, this application provides a pet bed, including a housing assembly 2, a filter assembly 4, a blower 5, a motor 6, and a pet bed assembly 3. The housing assembly 2 has a receiving cavity and an air inlet 22 and an air outlet 21 communicating with the receiving cavity. The filter assembly 4 is detachably disposed in the receiving cavity and is located near the air outlet 21. The air inlet end of the filter assembly 4 is connected to the air inlet 22, and the air outlet end of the filter assembly 4 is connected to the air outlet. The blower 5 is disposed in the receiving cavity and is located between the air outlet 21 and the air outlet end; it is used to discharge the air filtered by the filter assembly 4 from the air outlet 21. The motor 6 is disposed in the receiving cavity and is located near the air outlet 21. The output end of the motor 6 is connected to the blower 5. The pet bed assembly 3 is detachably connected to the housing assembly 2 and is located outside the receiving cavity and near the air outlet 21.

[0039] The housing assembly 2 serves as the structural foundation, providing a cavity as the core space to integrate components such as the filter assembly 4 and the blower 5, forming a sealed air duct. The air inlet 22 draws in external air or air from inside the pet's nest, which may be mixed with hair, odors, etc. The air outlet 21 discharges filtered clean air to the pet's nest assembly 3, creating a bottom-in, top-out air circulation with the bottom air inlet and top air outlet 21, improving ventilation efficiency and ensuring directional airflow from inlet to outlet. The filter assembly 4, located near the air outlet 21, intercepts pollutants before discharging the air. Specifically, unfiltered air is drawn in through the air inlet 22 and filtered by the filter assembly 4 to remove odors and dust. The filter removes dust and pet hair, improving air quality. Its detachable design allows for regular cleaning or replacement of the filter. The blower 5, located between the air outlet of the filter assembly 4 and the air outlet 21, works with the motor 6 to drive airflow circulation, creating negative pressure suction. The motor 6 drives the blower 5 to rotate, generating suction that accelerates the air filtered by the filter assembly 4 towards the air outlet 21, ensuring continuous airflow and maintaining ventilation within the pet bed. The pet bed assembly 3, positioned near the air outlet 21, directly receives the filtered clean airflow, creating a fresh air zone. This provides a clean and ventilated resting environment for pets, preventing stuffiness or odor buildup. Its detachable connection facilitates cleaning or replacement of the bedding.

[0040] In other words, outside air is drawn in through the air inlet 22, and after being filtered by the filter component 4, impurities are trapped, resulting in clean air. Under the action of the blower 5 and the motor 6, the clean air is blown out from the air outlet 21, which can flow to the pet bed component 3 or into the air to continuously improve the microenvironment of the pet bed.

[0041] In this embodiment, as Figure 5 As shown, the pet bed assembly 3 has a protrusion 322 at one end facing the housing assembly 2, and the housing assembly 2 has a corresponding mounting groove; the protrusion 322 is inserted into the mounting groove to detachably mount the pet bed assembly 3 onto the housing assembly 2, thereby enabling the pet bed assembly 3 to be quickly disassembled and installed for replacement and cleaning, etc.

[0042] In this embodiment, the pet nest assembly 3 includes a support frame 32 and a nest body 31; the support frame 32 has the protrusion 322, which is inserted into the mounting groove; the top edge of the support frame 32 is provided with an anti-detachment protrusion, and the anti-detachment protrusion is provided with a plurality of locking slots 321 distributed circumferentially; the bottom of the nest body 31 is provided with a locking hook 311 corresponding to the locking slot 321; wherein, the locking slot 321 and the locking hook 311 are engaged to place the nest body 31 on the support frame 32.

[0043] Preferred, such as Figure 3As shown, the slot member 321 includes a first slot portion 3211 and a second slot portion 3212 integrally connected, forming an L-shaped slot; the first slot portion 3211 has a guide slope at one end opposite to the second slot portion 3212, and the first slot portion 3211 is open; the diameter of the first slot portion 3211 is larger than the diameter of the second slot portion 3212; the hook member 311 includes a snap-fit ​​portion 3111, a connecting portion 3112, a first fixing portion and a second fixing portion, the first fixing portion and the second fixing portion being symmetrically arranged in the recess 31. The bottom is connected to both ends of the connecting part 3112, and the connecting part 3112 is located at the bottom of the socket 31. The end of the connecting part 3112 away from the socket 31 is connected to the snap-fit ​​part 3111, and the snap-fit ​​part 3111 and the second fixing part form an accommodating space. When the slot part 321 and the hook part 311 are engaged, the snap-fit ​​part 3111 slides into the guide slope of the first slot part 3211 and is inserted into the second slot part 3212, forming a self-locking structure, thereby making the snap-fit ​​part and the slot part 321 firmly connected, so that the socket 31 is firmly installed on the support frame 32. When disassembly is required, simply rotate the pet bed 31 in the opposite direction to remove the locking part 3111 from the second groove 3212 and allow it to leave through the guide slope of the first groove 3211. This makes it easy to remove the pet bed 31 for replacement or regular cleaning, providing a dedicated and comfortable resting place for the pet and helping it feel safe and relaxed.

[0044] In this embodiment, a cat bed pad is laid on the nest body 31. Preferably, the cat bed pad can be a cat bed pad; cat bed pads are typically made of memory foam, short fleece, or cooling gel material, conforming to the pet's body curves to provide support or seasonal temperature regulation, such as warmth in winter and heat dissipation in summer. The back of the cat bed pad has anti-slip particles or a silicone layer that cooperates with the inner surface of the nest body 31 to reduce pad displacement when the pet gets up. The cat bed pad is secured in the groove of the nest body 31 by Velcro or clips to prevent it from moving or falling off, and it can also be cleaned or replaced regularly to ensure the pet's health. In addition, the bottom of the nest body 31 has ventilation holes, which are connected to the air outlet 21 to form a micro-circulation with the purified airflow, avoiding dampness and stuffiness.

[0045] In this embodiment, the filter assembly 4 includes a filter support 41 and a filter element 42. The filter support 41 is detachably disposed in the receiving cavity of the housing assembly 2, and its axial first end is connected to the air inlet 22. The filter element 42 is coaxially sleeved in the filter support 41, and the filter element 42 includes a HEPA filter and an activated carbon filter layer in sequence along the airflow direction. The activated carbon filter layer is attached to the inner surface of the HEPA filter. A flow guiding gap is formed between the outer surface of the HEPA filter and the filter support 41, and the inner surface of the HEPA filter surrounds a purification chamber 421, which is connected to the air outlet through a second end.

[0046] The filter support 41 is detachable, allowing users to easily remove it from the housing assembly 2 for cleaning or replacement. The gap between the outer surface of the HEPA filter and the inner wall of the filter support 41 allows air to enter from the inlet and diffuse radially evenly, forming an airflow channel and preventing excessive local filtration pressure caused by concentrated airflow. The filter element 42 has a coaxial sleeve structure, with the HEPA filter and activated carbon filter layer tightly bonded together to form a cylindrical composite filter element, maximizing its filtration area. Then, under the action of the blower 5, air flows sequentially from the inlet 22 → guide gap → HEPA filter → activated carbon layer → purification chamber 421 → outlet → outlet 21 through negative pressure suction. Specifically, since a primary filter is installed at the inlet 22, external air undergoes preliminary filtration after entering through the inlet 22, intercepting some hair, dust, and other particulate matter. Then, air flows from both sides of the filter assembly 4... Air enters from the inlet, diffuses radially along the guide gaps, and permeates inwards through the outer surface of the HEPA filter, again intercepting particulate matter such as hair and dust. The filtered air continues to pass through the activated carbon layer, which adsorbs odors and volatile organic compounds, such as the ammonia smell of pet urine. Finally, it passes through the combined filtration of the HEPA filter and activated carbon, simultaneously addressing particulate matter and odor issues to obtain clean air. The clean air enters the purification chamber 421 and flows through the second end (i.e., the air outlet) of the filter support 41 to the air outlet 21, ensuring that the filtered air flows centrally to the blower 5. Finally, it is discharged from the blower 5 to the pet bed assembly 3 or directly into the air. This achieves the adsorption and collection of pet hair and dander, preventing the spread of hair throughout the room and allowing pets to continuously enjoy purified, fresh air, directly improving their breathing environment, reducing the impact of allergens, and enhancing comfort. In addition, the filter support 41 and the filter element 42 are modularly designed and can be disassembled as a whole or separately for easy cleaning or replacement.

[0047] In this embodiment, the HEPA filter is provided with a detachable filter cover 8 at one end near the air inlet 22, and the two ends of the filter cover 8 are respectively connected to the filter support 41 and cover the first end.

[0048] The filter cover 8 tightly seals the end of the HEPA filter near the air inlet 22, forming a physical barrier. This prevents air from directly entering the guide gap from the first end of the filter support 41, instead directing it into the air inlets on both sides. This ensures even airflow distribution across the entire outer surface of the HEPA filter, maximizing filtration area and preventing unfiltered air from directly short-circuiting into the purification chamber 421 from the HEPA filter end, thus avoiding air leakage. In other words, the sealed design maintains laminar flow and improves filtration efficiency. Both ends of the filter cover 8 are fixed to the filter support 41, ensuring no gaps between the filter cover 8, the filter element 42, and the filter support 41. This allows airflow to follow the path of air inlet 22 → air inlet → guide gap → HEPA filter → activated carbon layer. Simultaneously, the connection between the filter cover 8 and the filter support 41 is axially positioned, fixing the axial position of the HEPA filter and preventing displacement or deformation under airflow impact. It also prevents pet hair and large particles from directly impacting the HEPA filter inlet, extending its lifespan. In addition, the filter cover 8 can be removed separately, making it convenient for users to clean large debris accumulated at the end of the HEPA filter, such as pet hair clumps; if the HEPA filter or activated carbon layer needs to be replaced, the old filter material can be directly pulled out by opening the filter cover 8 without disassembling the entire filter assembly 4.

[0049] In this embodiment, a primary filter is provided at the air inlet 22 facing the filter cover 8, and the primary filter is spaced apart from the filter assembly 4. Preferably, the primary filter can be a nylon mesh or pre-filter cotton, mainly targeting visible pollutants; or some low-cost and reusable materials can be used to reduce the wear of the main filter material. Specifically, the primary filter, as a pre-filter, is located between the air inlet 22 and the filter cover 8. Air first passes through the primary filter from the air inlet 22, preferentially trapping large particulate pollutants such as pet hair, dust, and food residue; the primary filter maintains a certain distance from the filter assembly 4, forming a buffer space, so that the airflow is more evenly dispersed before entering the guide gap, avoiding excessively strong local airflow; that is, the initially purified air is buffered by the space and flows to the air inlets on both sides and the guide gap, preventing it from directly entering the main filter assembly 4, reducing the load on the HEPA filter, preventing large particles from clogging the high-precision filter material, protecting the HEPA filter, and extending its service life. It is known that the filter cover 8 is also provided with a strip groove 81, which is raised on the side facing the air inlet 22, so that some impurities with a certain weight that have not been filtered out in the purification chamber 421 can settle down here, thereby further improving the filtration efficiency.

[0050] In this embodiment, the HEPA filter has an air outlet at one end facing the blower 5; the air outlet is provided with a detachable air outlet cover 7, which protrudes towards the purification chamber 5 and is located at the second end.

[0051] The air outlet cover 7 has a raised section on the side facing the purification chamber 421, which concentrates and accelerates the airflow output from the purification chamber 421, forming a directional airflow channel and reducing turbulent energy loss. The raised section is embedded in the second end of the filter support 41, ensuring that the airflow is concentrated towards the blower 5, avoiding pressure loss caused by diffusion, and enhancing the negative pressure adsorption effect. Preferably, the air outlet cover 7 can also be equipped with a filter, so that the clean air is filtered again for impurities under the negative pressure of the blower 5. In addition, the detachable design allows users to directly open the air outlet cover 7 to clean the particles accumulated at the air outlet of the HEPA filter, such as activated carbon debris, or to replace the filter material without touching the blower 5.

[0052] In this embodiment, the outer shell assembly 2 is provided with a wear-resistant layer. The wear-resistant layer is wrapped around the outside of the shell and fixed by Velcro, clips, or environmentally friendly adhesive. The wear-resistant layer can be removed separately for cleaning or replacement without discarding the entire shell. Preferably, the wear-resistant layer can be a cat scratch cloth or a soft material to resist the scratching and biting behavior of pets, especially cats and dogs, preventing scratches, tears, or dents on the shell surface and extending the product's lifespan. At the same time, it acts as a buffer, reducing the noise and impact force when pets hit the shell, such as when pets are excited and bump into it.

[0053] In this embodiment, a base 1 is also provided at the air inlet 22. The base 1 is usually wider or heavier than the housing assembly 2 to reduce the risk of the pet bed being overturned by the pet. Preferably, a silicone pad or anti-slip texture can be added to the bottom of the base 1 to adapt to various floor materials such as wood flooring and tiles. The base 1 is provided with multiple air inlet grilles, which are connected to the air inlet 22 to divide the large air inlet 22 into several small airflow channels. This ensures the air intake volume while avoiding excessive local suction caused by a single large air inlet 22, making the air intake smoother and helping the blower 5 to operate stably and reduce noise. It also plays a role in pre-filtering and interception. The air inlet grilles first intercept large particles, such as pet toys and food pieces, and then the air is coarsely filtered through the primary filter, forming double protection. In addition, the user can disassemble the base 1 and the housing assembly 2 to directly rinse or brush the air inlet grilles to solve the problem of dust accumulation at the bottom.

[0054] In this embodiment, the receiving cavity is further provided with a wire groove 11 and a receiving groove 10 arranged opposite to each other. The receiving groove 10 is fixed to the PCB board 9 by clips or screws to ensure stable transmission of motor control signals and avoid displacement or poor contact caused by vibration of the blower 5. It can be seen that the PCB board 9 is electrically connected to the motor 6. The wire groove 11 is used to accommodate power cords, sensor wires, etc., and specifies the routing of the wires to prevent messy wire bundles from getting tangled around the impeller of the blower 5 or blocking airflow. It also prevents pets from biting the wires through gaps. In addition, the wire groove 11 avoids the disassembly path of the filter support 41, so there is no need to touch the circuit when maintaining the filter. Fixing the wires to the wire groove 11 also avoids friction with the impeller, reducing abnormal noise and the risk of short circuit.
