The inner wall of the guide groove is provided with a limiting portion, and the end of the middle shell facing the base has hook portions extending in the first direction distributed circumferentially. When the base is fixedly connected to the middle shell, the hook portion and the limiting portion cooperate to lock together; when the base is disassembled from the middle shell, the hook portion and the limiting portion disengage.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0017] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0018] like Figures 1 to 4As shown in the figure, an air purifier according to an embodiment of the present invention includes a housing 10 and a purification component. The housing 10 includes a base 11, a middle shell 12, and an upper shell 13 connected sequentially from bottom to top along a first direction X. The outer circumferential surface of the middle shell 12 has a plurality of air inlets 12a connected to its interior. The interior of the upper shell 13 is provided with two flow channels 13c that are symmetrical to its axis and independent of each other. The outer surface of the upper shell 13 is provided with air outlets 13a connected to the corresponding flow channels 13c at intervals along the first direction X. The purification component includes a mounting bracket 20, a fan 30, and a filter element 70. The mounting bracket 20 is mounted on the top of the middle shell 12. The surface of the mounting bracket 20 facing the base 11 has an extension portion 22 and a mounting portion 21 arranged side by side along the first direction X. The extension portion 22 has an air outlet channel connecting the flow channels 13c and the interior of the middle shell 12. The filter element 70 is installed in the air outlet channel. The fan 30 is rotatably mounted on the mounting portion 21 to accelerate the entry of external air into the middle shell 12.

[0019] Each flow channel 13c is connected to a set of air outlets 13a, so that clean air can flow out simultaneously from multiple layers of air outlets 13a, thereby covering spaces at different heights (such as low-altitude areas close to the ground and medium-high areas near the table), thus forming a three-dimensional air outlet effect and accelerating the diffusion and circulation of clean air in the room.

[0020] For example, multiple air inlets 12a are distributed circumferentially on the outer peripheral surface of the middle shell 12 to form 360° air intake without dead angles. Compared with the existing single-sided or double-sided air intake method, it can increase the air intake area, avoid air intake congestion, reduce air intake resistance, and thus provide sufficient air flow for subsequent purification stages.

[0021] In this embodiment, when the air purifier is started, the fan 30 starts to operate, so that after it rotates, it will actively create a stable negative pressure environment inside the middle shell 12, thereby drawing in outside air through the air inlet 12a into the middle shell 12. The air entering the middle shell 12 will flow towards the air outlet under the continuous guidance of the negative pressure. At this time, the filter element 70 will purify the air, and then it will flow into the two flow channels 13c inside the upper shell 13 and be discharged through the air outlet 13a on the outer surface of the upper shell 13. This can efficiently purify the air and quickly improve the indoor air quality.

[0022] In other words, the air purifier uses multiple air inlets 12a on the outer periphery of the middle shell 12 to form a 360° air intake without dead angles, and works with the filter element 70 installed in the air intake channel to purify the incoming air. Then, the air is discharged through two axially symmetrical independent flow channels 13c and corresponding air outlets 13a, thereby forming a three-dimensional air outlet and improving the diffusion efficiency and purification efficiency of the purified air.

[0023] In addition, the base 11, the middle shell 12 and the upper shell 13 are connected from bottom to top along the first direction X to form a three-section structure of the shell 10. Compared with the existing one-piece shell 10, the middle shell 12 does not need to reserve extra space to adapt to the air outlet structure, and the upper shell 13 does not need to accommodate the purification core components, thus avoiding the waste of space caused by functional overlap and compressing the radial and axial dimensions of the shell 10 as a whole.

[0024] In one possible implementation, the end face of the base 11 facing the middle shell 12 has a plurality of guide portions extending in a first direction X distributed circumferentially. A guide groove is provided between two adjacent guide portions, and a limiting portion is provided on the inner wall of the guide groove. The end of the middle shell 12 facing the base 11 has hook portions extending in the first direction X distributed circumferentially. When the base 11 and the middle shell 12 are fixedly connected, the hook portions and the limiting portions cooperate and lock together. When the base 11 and the middle shell 12 are disassembled, the hook portions disengage from the limiting portions.

[0025] In other words, by distributing multiple guide parts circumferentially on the end face of the base 11 and forming guide grooves between adjacent guide parts, during assembly, rotating the base 11 or the middle shell 12 allows the hook part on the middle shell 12 to slide along the guide groove until the base 11 and the middle shell 12 are assembled in place. The hook part then slides to a position that engages with the limiting part to form a lock, thus quickly completing the fixed connection between the middle shell 12 and the base 11 and preventing the base 11 and the middle shell 12 from becoming loose. When it is necessary to disassemble the base 11 and the middle shell 12, simply rotate the middle part or the base 11 in the opposite direction to allow the hook part to slide along the guide slope of the limiting part, thereby freeing it from the constraint of the limiting part. This process eliminates the need for tools such as screwdrivers and wrenches, greatly simplifying the disassembly and assembly process and facilitating daily maintenance by users or maintenance personnel.

[0026] In one possible implementation, the mounting bracket 20 has a plurality of first mounting blocks 40 extending along the first direction X at one end facing the upper shell 13, and a plurality of second mounting blocks 50 are distributed circumferentially on the inner wall of the upper shell 13 facing the middle shell 12. The second mounting blocks 50 are arranged in a one-to-one correspondence with the first mounting blocks 40, and the second mounting blocks 50 and the first mounting blocks 40 are detachably connected. That is, when assembling the upper shell 13 and the middle shell 12, it is only necessary to align the upper shell 13 and the middle shell 12 and ensure that the second mounting blocks 50 are aligned with the first mounting blocks 40 to complete the fixed connection between the upper shell 13 and the middle shell 12; when it is necessary to disassemble the upper shell 13 and the middle shell 12, it is only necessary to pull the upper shell 13 upward to separate the second mounting blocks 50 from the first mounting blocks 40 to complete the disassembly. The structure is simple and the assembly and disassembly are convenient.

[0027] Specifically, the second mounting block 50 has a plug-in hole at one end near the first mounting block 40, and the first mounting block 40 has a plug-in post 60 at one end near the second mounting block 50, with the plug-in post cooperating with the plug-in hole.

[0028] In one possible implementation, the corresponding air outlets of the two flow channels 13c are located on the same side of the upper shell 13. That is, if the air outlets are located on opposite sides, the clean air will flow in opposite directions, which may create airflow collisions in the room, causing local air stagnation (such as turbulent airflow in the center of the room). In this embodiment, the air outlets 13a of the two flow channels 13c are located on the same side, so that the clean air flows in the same direction (such as towards the center of the room or a specific area), promoting the formation of directional circulation of indoor air, avoiding disorderly airflow loss, and ensuring that the purified air is accurately applied to the area required by the user.

[0029] In one possible implementation, the upper shell 13 has a perforated hole 13b, and two air outlets 13a are symmetrical about the central axis of the perforated hole 13b.

[0030] In one possible implementation, an LED light strip is also included, which is installed along the first direction X on the inner wall of the perforated hole. Thus, when used in the bedroom, the LED light strip provides a soft, low-brightness light source, eliminating the need for users to turn on the main light when getting up at night. This avoids strong light irritating the eyes and does not disturb other roommates, achieving the dual functions of air purification and a night light. Furthermore, in practical use, multiple color lights (such as cool white light, warm yellow light, and gradient light) can be preset, allowing users to adjust them according to their interior decoration style or mood, upgrading the purifier from a functional appliance to a decorative element for home ambiance, adapting to the aesthetic needs of diverse spaces such as living rooms and studies.

[0031] In one possible implementation, the base 11 has multiple anti-slip protrusions distributed circumferentially on its surface opposite to the middle shell 12, and anti-slip pads are affixed to the anti-slip protrusions. That is, the circumferentially distributed protrusions support and contact surface at multiple points, thereby ensuring stability during use. Furthermore, since the anti-slip pads are affixed to the anti-slip protrusions, if a local anti-slip pad is worn, the corresponding anti-slip pad can be replaced individually without replacing the entire base 11, reducing maintenance costs and extending the effective lifespan of the overall anti-slip function.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
