Description

Technical Field

[0002] As people's requirements for home cleanliness and hygiene continue to increase, sweeping robots are becoming more and more popular in daily life. During the operation of sweeping robots, efficient filtering components play a key role in the cleaning effect and indoor air quality.

[0003] Publication (announcement) number: CN211936058U, discloses a filtering device for a sweeping machine, including a filter frame, a front end surface of the filter frame is provided with a dust removal component 1 for intercepting larger dust through ultrasonic welding, and a rear end surface of the filter frame is provided with a dust removal component 2 for secondary filtration. Larger dust is intercepted and filtered for the first time through the filter grid, and then filtered for the second time through the Hypa filter, so that the Hypa filter is not easy to get dirty, and the Hypa filter and the filter grid can be disassembled for cleaning and reused, thereby reducing costs.

[0004] However, the filter device lacks dynamic dust collection and suction effect. During use, the dust contacts the single filter surface, which makes the filter easy to be clogged, resulting in reduced subsequent suction force, affecting the suction effect. It also lacks automatic cleaning function, and personnel are required to frequently replace and clean the filter, increasing the labor burden of the personnel.

[0010] Furthermore, the vent hole is communicated with the air blowing duct.

[0011] Furthermore, a one-way plate is rotatably connected to the front of the dust exhaust duct.

[0012] Furthermore, clamping blocks are symmetrically fixed inside the rotating disk, and the rotating disk is clamped with the filter cartridge via the clamping blocks.

[0013] Furthermore, the right end of the filter cartridge is located inside the cover cartridge.

[0014] Furthermore, the front end of the drawer penetrates through the front surface of the casing, the drawer is plugged into the casing, and a plurality of through-type exhaust holes are provided on the front surface of the drawer, and the exhaust holes are communicated with the interior of the drawer.

[0015] The beneficial effects of the sweeper filter assembly with an antibacterial dust bag of the present invention are:

[0016] (1) The present invention has efficient dust suction and dust collection functions

[0017] The fan drive and negative pressure dust suction work together; the fan blows air from right to left, forming negative pressure inside the filter cartridge. With the help of the powerful suction force of the air intake and dust suction ports, dust and debris of different particle sizes on the ground under the casing can be quickly and efficiently attracted to the surface of the filter cartridge, greatly improving the dust capture ability of the sweeper and ensuring that as little dust as possible remains on the ground during the cleaning process.

[0018] Dynamic dust collection: While the motor drives the sweeper to move, the gear transmission drives the turntable to rotate, and the turntable further drives the filter cartridge to rotate, so that the dust-adsorbed part is orderly rotated to the dust discharge duct. When this part of the filter cartridge moves to the windshield, the dust automatically falls into the dust discharge duct due to the loss of negative pressure attraction, and slides into the dust bag for collection, realizing a dynamic, continuous and efficient dust collection process, avoiding excessive dust accumulation on the filter cartridge and affecting the dust collection efficiency.

[0019] (2) The present invention has a self-cleaning mechanism for the filter cartridge

[0020] Internal and external airflows clean together: When the fan blows air outward, the airflow enters the air duct through the vents under the guidance of the hemispherical cover and blows the filter cartridge from the inside to the outside. This airflow can not only blow the residual dust inside the filter cartridge into the dust exhaust duct for collection, but also effectively prevent dust from accumulating inside the filter cartridge and clogging the filter holes, thus maintaining the good air permeability and filtering performance of the filter cartridge.

[0021] Intermittent impact cleaning: The overlapping or staggered air passages are achieved through the coordination of the gear set, gear ring and rotating cover. When the air passages are staggered and the interior of the hemispherical cover is closed, the airflow concentrates on impacting the filter cartridge, producing an intermittent blowing and cleaning effect. Compared with continuous weak airflow cleaning, intermittent strong impact can more effectively shake off the stubborn dust on the surface of the filter cartridge, further improving the self-cleaning efficiency of the filter cartridge.

DETAILED DESCRIPTION

[0032] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0033] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Reference Figure 1-8 A sweeping machine filter assembly with an antibacterial dust bag comprises a filter mechanism 3, a housing 1 is provided on the outer surface of the filter mechanism 3, side panels 2 are fixed to the front and rear surfaces of the housing 1, a motor 4 is fixed to the rear of the housing 1, a rotating shaft 5 is fixed to the left and right ends of the output shaft of the motor 4, the opposite ends of the two rotating shafts 5 respectively penetrate to the opposite sides of the two side panels 2, and are fixed with running wheels 1 6, the front of the opposite sides of the two side panels 2 are rotatably connected with running wheels 2 36, and a cover cylinder 7 is penetrated and connected to the inside of the right side panel 2;

[0035] The filter mechanism 3 includes a filter housing 8, a turntable 9 is rotatably connected to the left side of the filter housing 8, a fixed cylinder 10 is fixedly penetrated inside the side plate 2 on the left side, the right end of the fixed cylinder 10 is rotatably connected to the inside of the turntable 9, the turntable 9 is rotatably connected to the right side of the side plate 2 on the left side, a fan 11 is arranged inside the fixed cylinder 10, a windshield cylinder 12 is fixed to the right end of the fixed cylinder 10, a filter cylinder 15 is sleeved on the outer surface of the windshield cylinder 12, an air suction port 13 is opened at the lower right side of the windshield cylinder 12, and a plurality of front-to-rear through-type blowing ducts 14 are opened at the lower left side of the outer surface of the windshield cylinder 12, and the fixed cylinder 10 is left The fixed cylinder 10 is fixed to the right end of the fixed cylinder 10. A hemispherical cover 16 is fixed at the end, and the hemispherical cover 16 and the outer surface of the fixed cylinder 10 are connected to a rotating cover 17 for rotation together. A plurality of air passages 18 are opened through the outer surfaces of the rotating cover 17 and the hemispherical cover 16. A dust exhaust passage 19 is opened in the front of the turntable 9, and a dust suction port 20 is opened in the rear of the turntable 9. A drawer 21 is plugged into the front end of the turntable 9, and a dust bag 24 is arranged inside the drawer 21. The dust bag 24 adopts nano silver antibacterial technology. A slot 22 is provided at the rear of the upper surface of the drawer 21, and a frame 23 is plugged into the slot 22. The frame 23 is fixedly connected to the dust bag 24;

[0036] A gear 1 26 is fixed on the outer surface of the rotating shaft 5 located on the left side, and a gear 2 27 is meshed and connected in front of the gear 1 26. The left end of the gear 2 27 passes through the left side of the side plate 2 and is fixed with a gear 3 28. The gear 2 27 is meshed and connected with the outer surface of the rotating disk 9. A gear ring 29 is fixed on the outer surface of the rotating cover 17. The gear ring 29 and the rotating cover 17 are both rotatably connected to the side plate 2 on the left side. The gear 3 28 is meshed and connected with the gear ring 29. A plurality of through-type air holes 30 are commonly provided on the left and right sides of the fixed cylinder 10. An annular ring groove 31 is provided on the right side of the rotating disk 9. A plurality of groups of gear teeth 32 are fixed on the inner surface of the ring groove 31. The inside of the ring groove 31 is meshed and connected with a gear 4 33 through the gear teeth 32. The right end of the gear 4 33 passes through the inside of the dust exhaust duct 19 and is fixed with a rotating plate 34. The rotating plate 34 is rotatably connected to the inside of the dust exhaust duct 19. A one-way plate 35 is rotatably connected to the front of the inside of the dust exhaust duct 19. The air hole 30 is connected to the blowing duct 14.

[0037] When in use, the fan 11 blows air from right to left, so that negative pressure is formed inside the filter cartridge 15, so that dust and debris on the ground below the housing 1 are attracted to the surface of the filter cartridge 15 through the air suction port 13 and the dust suction port 20. At the same time, when the motor 4 drives the running wheel 16 to move the entire assembly, the turntable 9 is rotated through the gear 1 26 and the gear 2 27, and the turntable 9 drives the filter cartridge 15 to rotate, and the dust adsorbed part is rotated to the dust discharge duct 19. After moving to the windshield 12, the negative pressure attraction is lost, so that the dust on the surface of the filter cartridge 15 falls into the dust discharge duct 19 and naturally slides into the dust bag 24 for collection;

[0038] At the same time, when the fan 11 blows air outwards, the airflow enters the blowing duct 14 through the vent hole 30 under the obstruction of the hemispherical cover 16, and the airflow blows the filter cartridge 15 from the inside to the outside, so that the residual dust inside can be better collected in the dust discharge duct 19, and can blow the one-way plate 35 to reverse and open, and accelerate the collection of dust. When the gear 2 27 rotates, it will synchronously drive the gear 3 28 to rotate, and drive the rotating cover 17 to rotate through the gear ring 29, so that the air duct 18 on the rotating cover 17 overlaps or interlaced with the air duct 18 at the hemispherical cover 16. When the overlap is connected, the air blown by the fan 11 from left to right will be blown out directly, and basically will not enter the blowing duct 14 through the vent hole 30 to blow the filter cartridge 15. When the air duct 18 is interlaced to close the interior of the hemispherical cover 16, the airflow will take effect, thereby achieving an intermittent blowing and cleaning effect on the filter cartridge;

[0039] As the turntable 9 rotates, the gear teeth 32 inside the annular groove 31 will intermittently mesh with the gear four 33, causing the turntable 34 to intermittently rotate. When the turntable 34 rotates, the left end will come into contact with the surface of the filter cartridge 15, thereby assisting in cleaning and scraping off debris. After losing the meshing of the gear teeth 32, it will naturally fall and rotate to reset, so that the debris on the surface of the turntable 34 can naturally slide off for collection by the dust bag 24.

[0040] Reference Figure 6-8 A clamping block 37 is symmetrically fixed inside the turntable 9, and the turntable 9 is clamped with the filter cartridge 15 through the clamping block 37. The right end of the filter cartridge 15 is located inside the cover cylinder 7. The filter cartridge 15 can be replaced by opening the cover cylinder 7, and the replaced filter cartridge 15 is clamped with the turntable 9 through the clamping block 37, so that the filter cartridge 15 can rotate with the turntable 9 when the turntable 9 rotates.

[0041] Reference Figure 4-5 The front end of the drawer 21 penetrates through the front surface of the casing 1 , the drawer 21 is plugged into the casing 1 , and a plurality of through-type exhaust holes 25 are provided on the front surface of the drawer 21 , which are connected to the inside of the drawer 21 .

[0042] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
