[0033] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0034] See also Figure 1-Figure 7 As shown, the present invention provides a garbage separation device for a vacuum cleaner, comprising:

[0035] The vacuum cleaner body 7 is provided with a driving motor inside the vacuum cleaner body 7. The driving motor rotates with the fan to generate negative pressure adsorption force, so that dust is sucked into the dust box 10 from the air inlet pipe 6. A dust box 10 is provided below the vacuum cleaner body 7. The dust box 10 is used to collect garbage in cooperation with the fan inside the vacuum cleaner body 7. An air inlet pipe 6 connected with the dust box 10 is provided on the side wall of the vacuum cleaner body 7. A suction nozzle is provided at the end of the air inlet pipe 6 for easy cleaning with the vacuum cleaner.

[0036] The bottom cover 11 is snap-fitted and installed on the bottom of the dust box 10. The side of the bottom cover 11 is rotatably connected to the dust box 10. The bottom cover 11 is processed by a snap-fit ​​installation method, which can quickly realize the disassembly and installation of the bottom cover 11, thereby improving the installation efficiency.

[0037] The separation cover 4 is plugged and installed on the vacuum cleaner body 7. The separation cover 4 is used to classify the dust sucked into the dust box 10. After the dust enters the dust box 10 and contacts the separation cover 4, the larger dust will contact the separation cover 4 and then escape from the circulating airflow and remain at the bottom of the dust box 10, while the smaller dust and debris will move with the airflow and finally be filtered through the filter 5;

[0038] The filter 5 is snap-fitted and installed on the separation cover 4 to filter the dust in the dust box 10. The filter 5 is a circular ring structure and is snap-fitted and installed on the inner wall of the separation cover 4 so that when the airflow circulates, it must pass through the filter 5 before being discharged, thereby achieving the cleaning of the dust inside the airflow;

[0039] The air guide cone 8 has guide grooves 805 arranged at equal intervals on the circumferential outer wall of the air guide cone 8. There are five guide grooves 805, which are arranged from top to bottom and can guide the airflow passing through the filter 5 so that the airflow moves along the guide grooves 805. In addition, the surface of the guide groove 805 is an arc-shaped inclined surface, which can reduce the resistance of the airflow movement and further improve the airflow circulation rate.

[0040] The connecting hole 803 is provided at the bottom end of the guide groove 805. The connecting hole 803 extends into the air guide cone 8 so that the airflow can enter the air guide cone 8 for circulation. Since the air guide cone 8 adopts a structural design with an internal air guide column 807, the size of the air guide column 807 is smaller than the air guide cone 8, so that the airflow can move along the air guide column 807 after passing through the connecting hole 803 on the air guide cone 8, and finally pass through the ventilation hole on the air guide column 807, thereby realizing airflow circulation;

[0041] The air guide column 807 is arranged inside the air guide cone 8. A plurality of air inlet holes 804 are provided on the surface of the air guide column 807. The air guide column 807 is hollow inside, and the outlet for air circulation is only arranged at the top of the air guide column 807, that is, it is led out from the center of the air guide cone 8, so that during the air circulation process, the air flow is always ensured to pass through the filter screen 5 for filtering;

[0042] When in use, the airflow drives the fan to rotate under the action of the motor inside the vacuum cleaner body 7, and the negative pressure adsorption force generated by the fan drives the airflow to be introduced into the dust box 10 from the air inlet pipe 6. Since the air inlet pipe 6 and the dust box 10 are provided with sealing plates for preventing dust reflux, under the action of negative pressure, the sealing plates are opened, which will cause the airflow to move along the sealing plates, and then cause the airflow to rotate along the inner wall of the dust box 10. Under the action of this airflow circulation, the airflow will pass through the surface of the filter 5 to complete the preliminary filtration. At the same time, the airflow after passing through the inside of the filter 5 contacts the guide groove 805 on the surface of the air guide cone 8, enters the air guide cone 8 along the guide groove 805, and is discharged from the bottom It passes through the air guide column 807 at the bottom and is finally guided out from the air outlet on the top of the vacuum cleaner body 7. In this process, the dust and debris sucked into the dust box 10 are cleaned. It should be noted that the continuous movement of the circulating airflow will cause the debris inside the dust box 10 to move with the airflow. In order to prevent the airflow at the bottom of the dust box 10 from moving upward again, a separation cover 4 is specially provided to enable contact between dust and debris during the movement, thereby destroying the following state. At the same time, the continuous airflow circulation inside the dust box 10 can realize the stacking of dust and debris as much as possible, thereby improving the space utilization rate in the dust box 10 as much as possible and reducing the cleaning frequency.

[0043] In another embodiment, the separation cover 4 is provided with an outward-turned retaining edge structure, and the retaining edge is formed with a chamfer. The purpose of this structural design is to prevent the return wind generated when the airflow moves inside the dust box 10 from driving the dust and debris at the bottom of the dust box 10 to rise, so that the dust and debris with heavier weight rise again and contact the surface of the screen, thereby causing the screen to be blocked. In addition, through the retaining edge structure provided when the separation cover 4 is provided, the garbage at the bottom of the dust box 10 follows the airflow to rotate at the bottom of the dust box 10, and then is more evenly scattered in the dust box 10, thereby improving the space utilization rate inside the dust box 10. A filter 5 bracket 402 is provided above the separation cover 4, and a plurality of air holes are opened on the surface of the filter 5 bracket 402. The filter 5 is buckled and installed on the filter 5 bracket 402 to vent the through holes. The filter 5 is sealed so as to achieve filtration during the process of airflow passing through. The filter 5 bracket 402 is provided with a buckle 2 protrusion for installing the filter 5. The top of the filter 5 is provided with a groove corresponding to the position of the buckle 2 protrusion, which can be buckled on the surface of the filter 5 bracket 402 for fixing, ensuring that the filter 5 and the filter 5 bracket 402 are tightly combined, thereby improving the filtering ability of the airflow. A slot 405 for positioning the filter 5 is provided on the top surface of the separation cover 4. The slot 405 is provided on the surface of the separation cover 4, and its size and width match the filter 5. When installing the filter 5, the bottom of the filter 5 can be inserted into the slot 405, so that the air permeable part of the surface of the filter 5 matches the air permeable hole on the filter 5 bracket 402 to the greatest extent, thereby improving the airflow transmission efficiency.

[0044] In another embodiment, a bottom edge 802 is provided at the bottom of the air guide cone 8, wherein the bottom edge 802 of the air guide cone 8 contacts the separation cover 4 for easy matching and fixing, a positioning protrusion 801 is provided on the bottom edge 802, and a positioning groove 806 is provided on the bottom edge 802. The positioning groove 806 cooperates with the positioning protrusion 801 and the separation cover 4 to achieve the connection and fixation between the air guide cone 8 and the separation cover 4, thereby avoiding the shaking of components and generating noise during the operation of the vacuum cleaner.

[0045] In another embodiment, the separation cover 4 is provided with a threaded hole that cooperates with the positioning protrusion 801 for fixing. The position of the threaded hole corresponds to the positioning protrusion 801. When in use, it can be installed by bolts to achieve the connection between the separation cover 4 and the air guide cone 8. The separation cover 4 is provided with a fixing seat 404 that cooperates with the bottom edge 802. The fixing seat 404 corresponds to the positioning groove 806 in size and position, and can be installed by interlocking with each other to achieve rapid positioning between the air guide cone 8 and the separation cover 4.

[0046] In another embodiment, a HEPA sponge is disposed inside the air guide column 807 to further filter fine dust in the circulating airflow. The HEPA sponge can be replaced separately, thereby reducing the maintenance cost of the vacuum cleaner.

[0047] In another embodiment, a sealing ring 3 cooperating with the dust box 10 is provided on the bottom cover 11. The structural design of the sealing ring 3 can avoid air leakage in the gap between the dust box 10 and the bottom cover 11, thereby ensuring the stability of airflow circulation.

[0048] In another embodiment, a side bracket 1 is provided on the outer wall of the dust box 10, and the side bracket 1 is used to cooperate with the hanging and fixing of the vacuum cleaner for easy storage.

[0049] In another embodiment, a buckle 2 is provided on the outer wall of the bottom cover 11 , and the structural design of the buckle 2 can match with the groove on the outer wall of the dust box 10 , thereby realizing the flipping of the bottom cover 11 .

[0050] In another embodiment, a fixing groove 9 cooperating with the vacuum cleaner body 7 is provided on the inner wall of the dust box 10. Through the fixing groove 9, the dust box 10 can be rotatably fixed to achieve the connection between the dust box 10 and the vacuum cleaner body 7.

[0051] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
