Description

Technical Field

[0001] This utility model relates to a small household appliance, and in particular to a high-suction air purifier with a convenient filter cartridge replacement. Background Technology

[0002] A previously filed application by the same applicant for a high-suction, rotatable pet hair-removing air purifier (application number 2025211925175) includes a base, a main body, and an outer shell. A filter cartridge supporting the main body is installed at the center of the base. The outer shell is rotatably mounted on the bottom of the main body and is driven by a drive motor installed within the main body. Two to ten air inlets are evenly distributed circumferentially on the outer shell. An air outlet cover with several air outlets is installed at the top of the main body. The drive motor rotates the outer shell, allowing the air inlets to rotate around the air purifier, achieving a 360° omnidirectional air intake effect. This reduces the number of air inlets to minimize the total air intake area. This design increases the air intake speed of a single air inlet, significantly enhancing the suction power for pet hair without reducing the suction range, thus effectively improving suction efficiency. The base includes a bottom ring with a removable end cap at the center. Removing the end cap allows for replacement or cleaning of the filter canister, making the operation simple and convenient. However, in actual use, the applicant found that this method of replacing the filter canister requires lifting or laying the entire device down to expose the bottom end cap, which is rather cumbersome. Moreover, during this process, dust and other vibrations accumulated inside the filter canister fall directly onto the floor, requiring additional cleaning by the user. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a high-suction air purifier with easy filter replacement.

[0004] The technical solution adopted by this utility model to solve its technical problem is: A high-suction air purifier with easy-to-replace filter canister includes a base, a main body, an outer shell, and a filter canister. The outer shell is rotatably mounted on the bottom of the main body and is driven by a drive motor installed inside the main body. The filter canister is supported between the base and the main body, so that the lower end of the outer shell is suspended. A rotating ring driven by the drive motor is installed on the bottom of the main body. Several snap-fit ​​parts are arranged circumferentially inside the rotating ring. A fixing ring is installed on the upper end of the outer shell. The fixing ring has snap-fit ​​grooves corresponding to the snap-fit ​​parts. The snap-fit ​​parts are detachably installed in the snap-fit ​​grooves.

[0005] The bottom of the machine body is equipped with a first limiting ring to prevent the rotating ring from falling. A locking ring extends outward from the top surface of the first limiting ring, and the inner ring of the rotating ring abuts against the top surface of the locking ring.

[0006] An annular groove is provided at the abutment of the rotating ring and the locking ring, and rolling balls are evenly distributed in the annular groove.

[0007] The outer edge of the rotating ring extends downward to form an outer ring portion, and the buckling portion is disposed on the inner side of the outer ring portion; the inner side of the fixing ring extends upward to form a slot ring, and the buckling slot is disposed on the outer side of the slot ring.

[0008] The top surface of the buckle part is provided with a locking groove, and the buckle groove is provided with a locking point corresponding to the locking groove, and the locking point is embedded in the locking groove.

[0009] An anti-detachment ring is installed at the bottom of the outer shell, and a second limiting ring is installed on the base corresponding to the anti-detachment ring. The top surface of the inner ring of the anti-detachment ring mates with the bottom surface of the outer ring of the second limiting ring.

[0010] The beneficial effects of this utility model are as follows: A rotating ring driven by a drive motor is installed at the bottom of the machine body. Several buckle parts are arranged circumferentially inside the rotating ring. A fixing ring is installed at the upper end of the outer shell. A buckle groove is provided on the fixing ring corresponding to the buckle parts. The buckle parts can be detachably installed in the buckle groove. After the machine body is removed, the filter canister can be removed from the top without lifting or tilting the equipment, which simplifies the filter canister replacement / cleaning operation and avoids dust falling during the replacement process, thus improving the user experience.

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0014] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0015] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0016] Reference Figure 1-6 A high-suction air purifier with easy filter replacement includes a base 1, a main body 2, a shell 3, and a filter (not shown in the figure). The shell 3 is rotatably mounted on the bottom of the main body 2 and is driven by a drive motor 5 installed inside the main body 2. The filter is supported between the base 1 and the main body 2, so that the lower end of the shell 3 is suspended. A rotating ring 6 driven by the drive motor 5 (transmission is achieved through a gear structure) is installed at the bottom of the main body 2. Several latching parts 7 are arranged circumferentially inside the rotating ring 6. A fixing ring 8 is installed at the upper end of the shell 3. The fixing ring 8 is provided with latching grooves 9 corresponding to the latching parts 7. The latching parts 7 are detachably installed in the latching grooves 9. After removing the main body, the filter can be removed from the top without lifting or tilting the device, simplifying the filter replacement / cleaning operation and preventing dust from falling during replacement (it can be caught directly with a bucket or other tool when lifting), thus improving the user experience.

[0017] Furthermore, the installation direction between the latching part 7 and the latching groove 9 is the same as the rotation direction of the outer shell 3. When the rotating ring 6 rotates, the latching part 7 will push the fixing ring 8 to rotate, thereby causing the outer shell 3 to rotate, thus preventing the latching part 7 from disengaging from the latching groove 9 during the rotation of the outer shell 3.

[0018] When disassembling the filter canister, the user can directly rotate the outer casing 3 (the direction of rotation of the outer casing 3 when the device is working) to separate the latching part 7 from the latching groove 9, thereby allowing the entire body 2 to be removed. During installation, since the bottom of the outer casing 3 is abutting against the base 1, there is friction (the outer casing 3 can also be clamped, such as by clamping it with both legs, to prevent the outer casing 3 from rotating and affecting the installation). The installation can be completed by rotating the body 2.

[0019] Furthermore, the outer shell 3 is provided with 2-10 air inlets evenly distributed along its circumference. The outer shell 3 is driven to rotate by the drive motor 5, so that the air inlets can rotate around the air purifier to achieve a 360° all-area air intake effect. By reducing the number of air inlets to reduce the total air intake area, the air intake speed of a single air inlet is increased. This design significantly enhances the suction power for pet hair without reducing the hair suction range, effectively improving the hair suction efficiency.

[0020] The bottom of the body 2 is equipped with a first limiting ring 10 to prevent the rotating ring 6 from falling. The top surface of the first limiting ring 10 extends outward to form a locking ring 11. The inner ring of the rotating ring 6 abuts against the top surface of the locking ring 11. An annular groove is provided at the abutment point between the rotating ring 6 and the locking ring 11. Balls 12 are evenly distributed in the annular groove to reduce the friction between the two and improve the smoothness of the rotation of the rotating ring 6.

[0021] The outer edge of the rotating ring 6 extends downward to form an outer ring portion 4, and the snap-fit ​​portion 7 is disposed on the inner side of the outer ring portion 4; the inner side of the fixed ring 8 extends upward to form a slot ring 13, and the snap-fit ​​groove 9 is disposed on the outer side of the slot ring 13. The top surface of the snap-fit ​​portion 7 is provided with a snap-fit ​​groove 14, and the snap-fit ​​groove 9 is provided with a snap-fit ​​point 15 corresponding to the snap-fit ​​groove 14. The snap-fit ​​point 15 is embedded in the snap-fit ​​groove 14, which can not only ensure the precise fit between the rotating ring and the fixed ring, but also improve the firmness of the connection between the two, avoid the snap-fit ​​from loosening due to vibration during the operation of the equipment, and ensure the stability and safety of the equipment operation.

[0022] An anti-detachment ring 16 is installed at the bottom of the outer shell 3, and a second limiting ring 17 is installed on the base 1 corresponding to the anti-detachment ring 16. The top surface of the inner ring of the anti-detachment ring 16 mates with the bottom surface of the outer ring of the second limiting ring 17.

[0023] Furthermore, the height of the filter barrel is higher than the height of the outer shell 3. When the upper and lower ends of the filter barrel abut against the body 2 and the base 1 respectively, the outer shell 3 is lifted by the first limiting ring 10, the rotating ring 6 and the fixing ring 8, so that the lower end of the outer shell 3 is in a suspended state. At this time, there is a gap between the anti-detachment ring 16 and the second limiting ring 17 to avoid contact and friction, which would affect the rotation effect.

[0024] After the filter barrel is removed, the outer shell 3 replaces the filter barrel and becomes the support between the body 2 and the base 1.
