[0031] 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.

[0032] 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.

[0033] like Figures 1 to 3 As shown, this application provides a pet air purifier, including a main unit assembly 1, a filter assembly 2, and a base 3; the main unit assembly 1 includes a blower 13, a motor 14, and a housing 11; the blower 13 and the motor 14 are detachably connected to the housing 11, and the output end of the motor 14 is connected to the blower 13; the top of the main unit assembly 1 is provided with an air outlet 12; the filter assembly 2 includes a filter support 21 and a filter element 22 coaxially sleeved in the filter support 21; the filter support 21 is detachably disposed on the housing 11 away from the air outlet 12. One end of the air outlet 12; the filter element 22 includes a HEPA filter and an activated carbon filter layer in sequence along the airflow direction; a guide air duct is formed between the HEPA filter and the filter support 21, and the HEPA filter surrounds a purification chamber 24 that communicates with the air outlet 12; the bottom of the base 3 is provided with an air inlet 32; the end of the base 3 away from the air inlet 32 ​​is detachably connected to the filter support 21, and the base 3 and the filter support 21 are spaced apart; the air inlet 32 ​​communicates with the air inlet end of the filter element 22.

[0034] Air enters through the air inlet 32 ​​at the bottom of the base 3, forming a pre-diffusion chamber through the space between the base 3 and the filter support 21. This pre-diffusion air is evenly distributed to the airflow channel formed between the outer surface of the HEPA filter and the filter support 21, and then sequentially enters the HEPA filter and the activated carbon layer. Specifically, the HEPA filter intercepts physical pollutants, while the activated carbon layer chemically adsorbs them, resulting in dual purification. The purified air enters the purification chamber 24, and the outlet of the purification chamber 24 is directly connected to the air outlet 12, reducing secondary pollution of the purified air. With the cooperation of the motor 14 and the blower 13, the output of the motor 14 is directly connected to the blower 13, providing stable suction and creating a negative pressure zone in the purification chamber 24. This allows the purified air to be discharged more quickly through the air outlet 12 at the top of the main unit assembly 1, improving filtration efficiency. Furthermore, the components are modularly connected; for example, the filter support 21 and the outer shell 11, the filter support 21 and the filter element 22, and the outer shell 11 and the base 3 are all detachable, allowing for complete or separate disassembly for easy cleaning or replacement.

[0035] In this embodiment, the base 3 is typically wider or heavier to reduce the risk of the pet bed being overturned by the pet. Preferably, the bottom of the base 3 can be equipped with a silicone pad or anti-slip texture to adapt to various floor materials such as wood flooring and tiles. The base 3 is also equipped with multiple air inlet grilles, which are connected to the air inlet 32 ​​to divide the air inlet 32 ​​into several small airflow channels. This ensures sufficient airflow while preventing excessive local suction caused by a single air inlet 32, resulting in smoother air intake, which helps the blower 13 operate stably and reduces noise. It also serves as a pre-filter, with the air inlet grilles first intercepting large particles, such as pet toys and food pieces, before the air is further filtered through a coarse filter, creating double protection. The base 3 is 30mm above the ground, with air intake only at the lower perimeter. Due to the top-outlet and bottom-inlet design, air circulation is easily generated, increasing the pressure at the bottom air inlet 32 ​​and thus increasing the suction power and air exchange rate. This enhances the collection of hair and large particles, increasing purification efficiency. In addition, users can remove the base 3 and directly rinse or brush the air intake grille to solve the problem of dust accumulation at the bottom.

[0036] In this embodiment, as Figure 2 As shown, the filter support 21 is provided with multiple positioning posts 25, and the main unit 1 is provided with a corresponding positioning groove 15. When the positioning post 25 is inserted into the positioning groove 15, the main unit 1 is detachably connected to the filter assembly 2. The cooperation between the positioning post 25 and the positioning groove 15 can achieve precise alignment, so that users do not need to make repeated adjustments during assembly or replacement, thus improving the efficiency of disassembly and assembly. In addition, users can also disassemble the filter assembly 2 by disassembling the main unit 1 and the filter support 21 to clean or replace the filter, reducing maintenance difficulty and extending the service life of the equipment.

[0037] In this embodiment, the filter support 21 is provided with two button slots 211 arranged opposite to each other, and the base 3 is provided with a button assembly 31 that can be elastically reset; the button assembly 31 is located in the button slots 211, and the filter support 21 is locked or released by pressing.

[0038] In this embodiment, as Figures 2 to 3 As shown, the button assembly 31 includes a pressure plate portion 313, a button portion 312, a spring portion 311, and a latching portion 314. The pressure plate portion 313 is disposed within the base 3 and corresponds to the button slot 211. The button portion 312 is slidably disposed within the button slot 211. The end of the button portion 312 is provided with a protrusion 3121. The spring portion 311 is connected between the pressure plate portion 313 and the button portion 312 and is used to drive the button portion 312 to reset after being pressed. The latching portion 314 is disposed within the base 3 and engages with the protrusion 3121. When the button portion 312 is pressed, the protrusion 3121 disengages from the latching portion 314, making the filter support 21 detachable. That is, by pressing the button 312, the protrusion 3121 can be disengaged from the latch 314, realizing the quick unlocking of the filter support 21, simplifying the steps of filter replacement or cleaning, and improving the user experience; when not pressed, the protrusion 3121 and the latch 314 are tightly engaged to prevent the filter support 21 from accidentally disengaging due to vibration or airflow impact, thus ensuring the stability of the equipment operation.

[0039] It is understood that the spring part 311 automatically pushes the button part 312 back after being pressed, ensuring that the button returns to its initial position and avoiding structural loosening or misoperation due to failure to reset. Specifically: when the spring part 311 is in its original state, the latching part 314 remains engaged with the button slot 211; after pressing the button part 312, the spring part 311 is in a compressed state, causing the protrusion 3121 to disengage from the latching part 314. At this time, the base 3 can be separated from the filter element 22 on its upper part, thus achieving disassembly and assembly with only a single finger press, allowing for the replacement or cleaning of the filter element 22 and the base 3, and subsequent disassembly and replacement of the filter element 22.

[0040] In this embodiment, the HEPA filter has a detachable filter cover at one end near the air inlet 32, and the two ends of the filter cover are respectively connected to the filter support 21.

[0041] The filter cover tightly seals the end of the HEPA filter near the air inlet 32, forming a physical barrier. This allows air to enter from both sides of the air inlet, ensuring even airflow distribution across the entire outer surface of the HEPA filter. This maximizes the filtration area and prevents unfiltered air from directly short-circuiting into the purification chamber 24 from the end of the HEPA filter, thus avoiding air leakage. This sealed design maintains laminar flow and improves filtration efficiency. Both ends of the filter cover are fixed to the filter support 21, ensuring no gaps between the filter cover, filter element 22, and filter support 21. This allows airflow to follow the path of air inlet 32 ​​→ air inlet → guide gap → HEPA filter → activated carbon layer. Simultaneously, the connection between the filter cover and the filter support 21 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 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; 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, without disassembling the entire filter assembly2.

[0042] In this embodiment, a coarse filter is provided at the air inlet 32 ​​facing the filter cover, and the coarse filter is spaced apart from the filter assembly 2. Preferably, the coarse filter can be a nylon mesh or a 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 coarse filter, as a pre-filter, is located between the air inlet 32 ​​and the filter cover. Air first passes through the coarse filter from the air inlet 32, preferentially trapping large particulate pollutants such as pet hair, dust, and food residue; the coarse filter maintains a certain distance from the filter assembly 2, 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 2, 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. Large particles are concentrated on the bottom coarse filter screen, preventing the HEPA filter from filtering large particles. This extends the life of the HEPA filter, which can be replaced every few months or a year. The bottom can be cleaned frequently, and cleaning only the bottom makes disassembly and cleaning convenient.

[0043] In this embodiment, the HEPA filter is provided with a detachable air outlet cover 23, which is convex facing the purification chamber 24. This convex cover concentrates and accelerates the airflow output from the purification chamber 24, forming a directional airflow channel and reducing turbulent energy loss. The convex portion 3121 is embedded in the second end of the filter support 21, ensuring that the airflow is concentrated towards the blower 13, avoiding pressure loss caused by diffusion, and enhancing the negative pressure adsorption effect. Preferably, the air outlet cover 23 may also be provided with a filter screen, so that the clean air is filtered again for impurities under the negative pressure of the blower 13. In addition, the detachable design allows users to directly open the air outlet cover 23 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 13.

[0044] In this embodiment, the housing 11 also includes a receiving slot for holding a PCB board. The PCB board is electrically connected to the motor 14, ensuring the normal operation of the motor 14 and the stable transmission of control signals. The PCB board is secured to the receiving slot by clips or screws, ensuring stable transmission of control signals from the motor 14 and preventing displacement or poor contact caused by vibration of the blower 13. Furthermore, this design provides excellent waterproofing, protecting the PCB board and motor 14 from humid environments, thereby improving the overall stability and lifespan of the device.

[0045] In this embodiment, a wire groove is provided within the airflow guide duct to connect the host interface of the host component 1 and the base 3 interface of the base 3. The wire groove accommodates power cords, sensor wires, etc., defining the routing of the wires and preventing tangled wires from tangling around the impeller of the blower 13 or obstructing airflow. It also prevents pets from chewing and damaging the wires through gaps. Furthermore, the wire groove avoids the disassembly path of the filter support 21, eliminating the need to touch the circuitry when maintaining the filter. Fixing the wires to the wire groove also prevents friction with the impeller, reducing noise and the risk of short circuits.

[0046] In this embodiment, the top of the pet air purifier has an upward-opening mounting groove; the bottom of the pet bed assembly has a downward-extending mounting flange; wherein the mounting flange is slidably embedded in the mounting groove, allowing the pet bed assembly to be detachably mounted on the pet air purifier. Unfiltered air enters from the air inlet 32 ​​and is filtered by the filter assembly 2 to remove odors, dust, and pet hair, improving air quality. The blower 13 is located between the air outlet of the filter assembly 2 and the air outlet 12, and works with the motor 14 to drive airflow circulation, forming a negative pressure suction. That is, the motor 14 drives the blower 13 to rotate, generating suction to accelerate the air filtered by the filter assembly 2 towards the air outlet 12, ensuring continuous airflow and maintaining ventilation inside the bed. The pet bed assembly is positioned close to the air outlet 12, directly receiving the filtered clean airflow to form a fresh air zone, providing a clean and ventilated resting environment for the pet, avoiding stuffiness or odor buildup. It is also detachably connected for easy cleaning or replacement of the bedding.

[0047] In this embodiment, the pet air purifier has a wear-resistant layer on its exterior. This layer is secured with Velcro, clips, or environmentally friendly adhesive, allowing for individual removal for cleaning or replacement without disposing of the entire casing. Preferably, the wear-resistant layer can be a cat scratch cloth or a soft material to resist scratching and biting by pets, especially cats and dogs, preventing scratches, tears, or dents on the surface of the air purifier's casing and extending the product's lifespan. Simultaneously, it acts as a buffer, reducing noise and impact when a pet bumps into the air purifier, such as when the pet is excited.
