Description

Technical Field

[0001] This invention relates to a small household appliance, and more particularly to a pet hair removal air purifier. Background Technology

[0002] Existing pet hair-absorbing air purifiers have air intake grilles evenly distributed around the perimeter of their casing, enabling them to achieve 360° hair absorption. While this achieves a wide-area absorption effect, the total area of ​​the air intake grilles is too large. With a fixed airflow from the fan, the suction power distributed across each grille is relatively small, resulting in an unsatisfactory effect in absorbing pet hair. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a high-suction, rotatable pet hair-removing air purifier.

[0004] The technical solution adopted by this invention to solve its technical problem is: A high-suction, rotatable pet hair-removing air purifier includes a base, a main body, and a shell. A filter barrel supporting the main body is installed at the center of the base. The shell is rotatably installed at the bottom of the main body and is driven by a drive motor installed in the main body. 2-10 air inlets are evenly distributed around the circumference of the shell. An air outlet cover is installed at the top of the main body, and the air outlet cover has several air outlets.

[0005] The machine body includes an outer casing and a suction assembly installed inside the outer casing. The bottom of the outer casing has a first annular cavity with a lower opening. A rotating ring driven by the drive motor is installed inside the first annular cavity. The upper end of the outer casing is fixed to the rotating ring.

[0006] A first limiting ring is installed at the lower end of the first annular cavity to prevent the rotating ring from falling. The inner ring of the rotating ring is in contact with the top surface of the first limiting ring, and the outer ring of the rotating ring is fixedly connected to the upper end of the outer shell.

[0007] The top surface of the first limiting ring is provided with a plurality of arranged protruding rings, and the top surface of the protruding rings is an arc surface.

[0008] The drive motor has a drive gear mounted on its rotating shaft, and the inner wall of the rotating ring has an internal gear corresponding to the drive gear. The drive gear meshes with the internal gear for transmission.

[0009] The machine body also includes an inner housing that is installed inside the outer housing of the machine body by screws. The air outlet cover is fixed to the upper end of the inner housing of the machine body. A connector is installed at the bottom center of the air outlet cover. The suction assembly is fixed to the lower end of the connector. A grid hole communicating with the center of the filter barrel is provided at the bottom center of the inner housing of the machine body.

[0010] The bottom of the inner casing of the machine is equipped with a support ring with a lower opening, and the upper end of the filter barrel is inserted into the support ring.

[0011] The base includes a bottom ring, a detachable end cap is installed at the center of the bottom ring, the bottom of the filter bucket abuts against the surface of the end cap, the bottom ring is provided with a second annular cavity with an upper opening, an anti-detachment ring is rotatably installed in the second annular cavity, the lower end of the outer shell is fixed to the anti-detachment ring, and a second limiting ring is installed in the second annular cavity to prevent the anti-detachment ring from disengaging from the second annular cavity.

[0012] The outer ring of the second limiting ring covers the inner ring of the anti-detachment ring.

[0013] After the filter barrel and the end cap are installed, the anti-detachment ring separates from the second annular cavity and the second limiting ring.

[0014] The beneficial effects of this invention are as follows: This invention includes a base, a main body, and an outer shell. A filter barrel supporting the main body is installed at the center of the base. The outer shell is rotatably installed at the bottom of the main body and is driven by a drive motor installed inside the main body. 2-10 air inlets are evenly distributed around the outer shell along its circumference. An air outlet cover is installed at the top of the main body, and the air outlet cover has several air outlets. The drive motor drives the outer shell to rotate, so that the air inlets can rotate around the air purifier, achieving 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 hair suction efficiency. Attached Figure Description

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention 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 described herein can be combined with each other.

[0018] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0019] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0020] Reference Figure 1-10 A high-suction, rotatable pet hair-removing air purifier includes a base 1, a main body 2, and an outer shell 3. A filter barrel 4 supporting the main body 2 is installed at the center of the base 1. The outer 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. Two to ten air inlets 6 are evenly distributed circumferentially on the outer shell 3. An air outlet cover 7 is installed at the upper end of the main body 2, and the air outlet cover 7 has several air outlets 8. The drive motor 5 drives the outer shell 3 to rotate, allowing the air inlets 6 to rotate around the air purifier, achieving a 360° all-area air intake effect. By reducing the number of air inlets to decrease 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 removal range, effectively improving hair removal efficiency.

[0021] The main body 2 includes an outer casing 9 and a suction assembly 10 installed inside the outer casing 9. The suction assembly 10 serves as the power unit for the entire air purifier. When it is activated, the suction assembly 10 draws air out of the filter barrel 4 and discharges it through the air outlet 8. At the same time, a slight negative pressure is formed inside the filter barrel 4, thereby drawing in external air through the air inlet 6 and passing it through the barrel wall of the filter barrel 4 (the barrel wall of the filter barrel 4, including the bottom, is composed of filter material, which is generally non-woven fabric made of polypropylene, glass fiber, and other materials, and is made into a fine fiber mesh through a special process. When pet hair, dust particles, etc. are drawn in, they are filtered by the filter material, thereby purifying the air. The purified air enters the filter barrel 4, is then drawn out by the suction assembly 10, and discharged through the air outlet 8, thus achieving circulation).

[0022] The bottom of the outer casing 9 is provided with a first annular cavity 12 with a lower opening. A rotating ring 13 driven by the drive motor 5 is installed in the first annular cavity 12. The upper end of the outer casing 3 is fixed on the rotating ring 13. When the rotating ring 13 driven by the drive motor 5 rotates, it will synchronously drive the outer casing 3 to rotate, thereby enabling the air inlet 6 to rotate around the air purifier and achieve a 360° all-area air intake effect.

[0023] Furthermore, the two sides of the air inlet 6 are inclined surfaces, which are adapted to the rotation direction of the outer shell 3. When the outer shell 3 rotates, the external air is pushed by the side wall of the air inlet 6 and enters the interior of the outer shell 3 along the side wall, thereby improving the suction effect to a certain extent. The principle is similar to that of an impeller. However, the inclination angle of the side wall of the air inlet 6 needs to be set while maintaining its shape. The outer shell 3 of this product is still a cylindrical structure. It will not form convex blades like an impeller in order to achieve a larger suction volume. The air inlet is set on the convex part.

[0024] Furthermore, a first limiting ring 14 is installed at the lower end of the first annular cavity 12 to prevent the rotating ring 13 from falling. The first limiting ring 14 blocks the opening of the inner ring portion of the first annular cavity 12, thereby opening the lower side of the outer ring portion of the first annular cavity 12. The outer wall (i.e., the outer side) of the inner ring portion is connected to the inner wall (i.e., the inner side) of the outer ring portion. When the rotating ring 13 is installed in the first annular cavity 12, the inner ring portion of the rotating ring 13 contacts the top surface of the first limiting ring 14 and is restricted by the first limiting ring 14 to prevent it from falling. The outer ring portion of the rotating ring 13 is exposed by the opening of the first annular cavity 12, providing sufficient space for fixed connection with the upper end of the outer shell 3.

[0025] Furthermore, the top surface of the first limiting ring 14 is provided with a plurality of arranged protruding rings 15, the top surface of the protruding rings 15 being an arc surface, which reduces the contact area with the rotating ring 13, thereby reducing the friction between the two and improving the smoothness of the rotation of the rotating ring 13.

[0026] The drive motor 5 has a rotating shaft with a drive gear 16 installed on it. The inner wall of the rotating ring 13 is provided with an inner gear 17 corresponding to the drive gear 16. The drive gear 16 and the inner gear 17 mesh and transmit power.

[0027] The base 1 includes a bottom ring 18, and a detachable end cap 19 is installed at the center of the bottom ring 18. The bottom ring 18 and the end cap 19 can be connected by a common snap-fit ​​method. The bottom of the filter bucket 4 abuts against the surface of the end cap 19. The filter bucket 4 can be replaced or cleaned by removing the end cap 19. The operation is simple and convenient.

[0028] The bottom ring 18 is provided with a second annular cavity 20 with an upper opening. An anti-detachment ring 21 is rotatably installed in the second annular cavity 20. The lower end of the outer shell 3 is fixed to the anti-detachment ring 21. A second limiting ring 22 is installed in the second annular cavity 20 to restrict the anti-detachment ring 21 from detaching from the second annular cavity 20. The second limiting ring 22 has a similar function to the first limiting ring 14, which is to block the opening of the inner ring portion of the second annular cavity 20, thereby opening the lower side of the outer ring portion of the second annular cavity 20. The outer wall (i.e., the outer side) of the inner ring portion is connected to the inner wall (i.e., the inner side) of the outer ring portion. When the anti-detachment ring 21 is installed in the second annular cavity 20, the inner ring portion of the anti-detachment ring 21 is covered by the second limiting ring 22, thereby being restricted by the second limiting ring 22 to prevent detachment. The outer ring portion of the anti-detachment ring 21 is exposed by the opening of the second annular cavity 20, providing sufficient space for fixed connection with the lower end of the outer shell 3.

[0029] Before assembling the outer shell 3 into the complete machine, the rotating ring 13 and the anti-detachment ring 21 need to be installed at the upper and lower ends of the outer shell 3 respectively. The lower end of the outer shell 3 is installed in the second annular cavity 20 of the bottom ring 18 (that is, the anti-detachment ring 21 is installed in the second annular cavity 20). Then, the second limiting ring 22 is fixed to the bottom ring 18 with screws. At this time, the connection between the base 1 and the outer shell 3 is completed (the end cover 19 is installed after the filter bucket 4 is installed). Then, the upper end of the outer shell 3 is installed in the first annular cavity 12 at the bottom of the outer casing 9 of the machine body. Then, the first limiting ring 14 is fixed to the outer casing 9 of the machine body with screws. At this time, the connection between the outer casing 9 of the machine body and the outer shell 3 is completed (before the outer shell 3 is installed, the first limiting ring 14 and the second limiting ring 22 can be placed inside the outer shell 3 to avoid the situation where some parts cannot be put in after installation).

[0030] Preferably, after the filter bucket 4 is installed with the end cap 19, the anti-detachment ring 21 separates from the second annular cavity 20 and the second limiting ring 22. That is, at this time, the lower end of the outer shell 3 is in a free end state, eliminating the friction between it and the base 1, thereby improving the smoothness of the rotation of the outer shell 3.

[0031] Preferably, the thickness of the rotating ring 13 is slightly less than the depth of the first annular cavity 12, so that under the influence of gravity, the rotating ring 13 presses down and abuts against the first limiting ring 14, and the top surface of the rotating ring 13 is separated from the first annular cavity 12, further reducing the frictional force on the rotating ring 13 (e.g., ...). Figure 5 (As shown in D and E).

[0032] Furthermore, there is a gap between the outer wall of the first annular cavity 12 and the outer shell 3 (e.g., Figure 4 As shown in C), this reduces the frictional force on the outer shell 3.

[0033] In this embodiment, when the filter barrel 4 is not installed, the outer shell 3 serves as a support to support the body 2. At this time, the lower end of the outer shell 3 contacts the base 1, and the top surface of the rotating ring 13 abuts against the top surface of the first annular cavity 12. In addition, since the body 2 has a certain weight, it will further increase the pressure at each contact point, thereby increasing the friction. If the drive motor 5 is started at this time, the rotation of the outer shell 3 will be severely hindered, or even unable to rotate.

[0034] When the filter barrel 4 and end cap 19 are installed, the filter barrel 4 replaces the outer shell 3 and serves as a support for the body 2. Under the influence of gravity, the rotating ring 13 presses down and abuts against the first limiting ring 14. The top surface of the rotating ring 13 is separated from the first annular cavity 12. In addition, the lower end of the outer shell 3 will separate from the top of the outer wall of the second annular cavity 20. At the same time, the anti-detachment ring 21 and the second limiting ring 22 will not abut against each other, thus making the lower end of the outer shell 3 a free end (the height of the filter barrel 4 can be adjusted by using data such as the upper end of the outer shell 3).

[0035] When the filter barrel 4 is replaced, the first limiting ring 14 and the second limiting ring 22 serve to connect the two ends of the body 2, the base 1 and the outer shell 3.

[0036] The body 2 also includes an inner housing 23 installed inside the outer housing 9 by screws. The air outlet cover 7 is fixed to the upper end of the inner housing 23. A connector 24 is installed at the bottom center of the air outlet cover 7. The suction assembly 10 is fixed to the lower end of the connector 24. A grid hole 25 communicating with the center of the filter barrel 4 is provided at the bottom center of the inner housing 23. The installation between the filter barrel 4 and the bottom of the inner housing 23 requires a certain degree of sealing, such as by providing a first convex ring at the bottom of the inner housing 23. The top of the filter canister 4 is provided with a second protruding ring. When the filter canister 4 is installed, the second protruding ring is sleeved on the outside of the first protruding ring, thereby improving the sealing between the filter canister 4 and the inner housing 23 of the machine body. If the sealing between the filter canister 4 and the inner housing 23 of the machine body is poor, when the suction assembly 10 sucks air, it directly draws air in through the installation gap between the filter canister 4 and the inner housing 23 of the machine body. This part of the air is not filtered by the filter canister 4, resulting in pet hair and other substances directly entering the machine body 2, causing damage to the equipment.

[0037] Furthermore, a support ring with a lower opening is installed at the bottom of the inner casing 23 of the machine body. The upper end of the filter barrel 4 is inserted into the support ring. The support ring guides the installation of the filter barrel 4, increases the contact area of ​​the filter barrel 4, disperses the pressure on the top of the filter barrel 4, and increases its service life.
