Description

Technical Field

[0001] This invention relates to the field of household dust purification technology, and in particular to a smart home dust purification device. Background Technology

[0002] With the continuous development of smart home environments, indoor air quality has become a major concern. As urbanization accelerates, industrial activities increase, and people's daily activities expand, the levels of pollutants such as dust in indoor air are rising. This dust not only affects the cleanliness of the indoor environment but may also carry bacteria, viruses, and other harmful substances, posing a potential threat to human health. Therefore, efficient dust purification devices are crucial for ensuring air quality in smart home environments.

[0003] Currently, most dust purification devices on the market use a filtration principle, with the filter cartridge playing a crucial role as the core filtration component. During filtration, dust is continuously adsorbed and trapped on the surface of the filter cartridge. As filtration time increases, the amount of dust accumulated on the filter cartridge surface gradually increases, causing a sharp decrease in the filter cartridge's air permeability, leading to rapid clogging and preventing the achievement of good air purification results.

[0004] For example, patents CN208553576U (titled "A Dust Purification and Treatment Device for Smart Home") and CN218687808U (titled "A Dust Purification and Treatment Apparatus for Smart Home") both have the aforementioned problems. Therefore, it is now necessary to design a dust purification and treatment apparatus for smart homes. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dust purification device for smart homes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A smart home dust purification device includes a housing. The housing contains an air outlet chamber and a filter chamber, with the filter chamber located below the air outlet chamber. An air inlet communicating with the filter chamber is located on the side wall of the housing. A filter cylinder is located inside the filter chamber, with a first rotating pipe and a second rotating pipe fixedly connected to its two ends. Both the first and second rotating pipes penetrate the inner wall of the filter chamber and are rotatably connected to the inner wall of the filter chamber via bearings. An exhaust fan is installed on the outer wall of the housing. An exhaust pipe is connected to the input end of the exhaust fan, and the end of the exhaust pipe furthest from the exhaust fan is connected to the first rotating pipe via a rotary joint. The output end of the exhaust fan communicates with the interior of the air outlet chamber. A rotating mechanism connected to the first rotating pipe is located on the outer wall of the housing. A dust removal mechanism located close to the filter cylinder is located inside the filter chamber and is connected to the rotating mechanism via a transmission mechanism. A back-blowing mechanism is located inside the filter cylinder and is connected to the dust removal mechanism.

[0008] As a further improvement of the present invention, the rotating mechanism includes a motor fixedly mounted on the outer wall of the housing, the output shaft of the motor being fixedly connected to a rotating shaft, a fixing frame being fixedly connected to the outer wall of the housing, the end of the rotating shaft away from the motor being fixedly connected to the inner side wall of the fixing frame, a first gear being fixedly sleeved on the side wall of the rotating shaft, and a second gear being fixedly sleeved on the side wall of the first rotating tube, the first gear meshing with the second gear.

[0009] As a further improvement of the present invention, the ash removal mechanism includes a vibrating rod disposed inside the filter chamber. A protrusion is fixed on the side wall of the vibrating rod, and the protrusion contacts the filter cylinder. Slide grooves are provided on the opposite side walls of the filter chamber. The two ends of the vibrating rod slide inside the two slide grooves respectively. Two guide rods are provided through the vibrating rod and are slidably connected to the vibrating rod. The two guide rods are located inside the two slide grooves respectively. The two ends of the guide rods are fixed on the inner wall of the slide grooves. A spring is fitted on the guide rod. One end of the spring is fixed on the inner wall of the slide groove, and the other end of the spring is fixed on the vibrating rod. A first magnetic block is fixed on the side wall of the vibrating rod. A rotating rod is provided on one side of the vibrating rod. The two ends of the rotating rod penetrate the inner wall of the filter chamber and extend to the outside of the housing. The rotating rod is rotatably connected to the inner wall of the filter chamber through a bearing. A second magnetic block that cooperates with the first magnetic block is fixed in the middle of the side wall of the rotating rod.

[0010] As a further improvement of the present invention, the transmission mechanism includes a first synchronous pulley and a second synchronous pulley. The first synchronous pulley is fixedly sleeved on the rotating shaft, and the second synchronous pulley is fixedly sleeved on the rotating rod. A synchronous belt is fitted between the first synchronous pulley and the second synchronous pulley.

[0011] As a further improvement of the present invention, the backflush mechanism includes a backflush hood disposed inside the filter cylinder, the backflush hood fitting against the inner wall of the filter cylinder, a connecting pipe connected to the side wall of the backflush hood, the connecting pipe passing through a second rotating pipe, a piston cylinder fixed to the side wall of the housing, an air outlet pipe and an air intake pipe connected to the side wall of the piston cylinder, both the air outlet pipe and the air intake pipe having a one-way valve inside, the end of the air outlet pipe away from the piston cylinder being connected to the connecting pipe, a piston disposed inside the piston cylinder, a connecting rod rotatably connected to the piston, a turntable fixedly sleeved on the side wall of the rotating rod, and the end of the connecting rod away from the piston being rotatably connected to the edge of the side wall of the turntable.

[0012] As a further improvement of the present invention, an air hood communicating with the air outlet cavity is fixed on the side wall of the housing.

[0013] As a further improvement of the present invention, the filter cartridge is a cylindrical metal dust filter.

[0014] As a further improvement of the present invention, a guide plate is fixed on the inner wall of the air inlet.

[0015] The beneficial effects of this invention are:

[0016] By activating the exhaust fan, a negative pressure is created inside the filter cartridge. Air entering the filter chamber through the air inlet is then filtered through the filter cartridge, and dust is adsorbed and trapped on its surface. The rotating mechanism drives the filter cartridge to rotate, filtering and removing dust from the air at different points on its surface. This effectively prevents the filter cartridge from clogging quickly and greatly extends its service life.

[0017] By setting up a dust removal mechanism, when the filter cartridge rotates, the transmission mechanism drives the dust removal mechanism to operate. The operation of the dust removal mechanism vibrates the surface of the filter cartridge, making it easier for dust to detach from the filter cartridge. This achieves automatic cleaning and dust removal of the filter cartridge, effectively maintaining its filtration performance and ensuring a good air filtration and purification effect.

[0018] By setting up a back-blowing mechanism, while the filter cartridge is being cleaned and dust removed, the rotation of the rotating rod drives the turntable to rotate. Then, through the linkage of the connecting rod, the piston can be driven to move back and forth inside the piston cylinder. This allows air to be pumped into the back-blowing hood through the air outlet box connecting pipe. This back-blowing hood then blows the dust off the filter cartridge from the inside, making it easier for the dust adhering to the filter cartridge surface to be removed and further improving the dust removal effect of the filter cartridge.

[0019] The intelligent home dust purification device of the present invention can drive the filter cartridge to rotate, filter at different positions to prevent clogging and increase the service life, and realize automatic vibration dust removal of the dust removal mechanism to ensure filtration performance. In addition, it can back-blown from the inside of the filter cartridge to enhance dust removal efficiency. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Reference Figures 1-5A smart home dust purification device includes a housing 1. The housing 1 has an air outlet chamber 27 and a filter chamber 26 inside. Further, a pull-out groove can be opened on the inner wall of the filter chamber 26, and a pull-out box can be set for collecting dust. The filter chamber 26 is located below the air outlet chamber 27. An air inlet 5 communicating with the filter chamber 26 is opened on the side wall of the housing 1. A guide plate 6 is fixed on the inner wall of the air inlet 5. An air outlet hood 3 communicating with the air outlet chamber 27 is fixed on the side wall of the housing 1. A filter cylinder 7 is provided inside the filter chamber 26. The filter cylinder 7 is a cylindrical metal dust filter.

[0028] The filter cartridge 7 is fixedly connected to a first rotating tube 18 and a second rotating tube 25 at its two ends. Both the first rotating tube 18 and the second rotating tube 25 penetrate the inner wall of the filter chamber 26, and the first rotating tube 18 and the second rotating tube 25 are rotatably connected to the inner wall of the filter chamber 26 through bearings. An exhaust fan 2 is installed on the outer wall of the housing 1. The input end of the exhaust fan 2 is connected to an exhaust pipe 4. The end of the exhaust pipe 4 away from the exhaust fan 2 is connected to the first rotating tube 18 through a rotary joint 16. The output end of the exhaust fan 2 is connected to the inside of the air outlet chamber 27.

[0029] The outer wall of the housing 1 is provided with a rotating mechanism connected to the first rotating tube 18. The rotating mechanism includes a motor 8 fixedly installed on the outer wall of the housing 1. The output shaft of the motor 8 is fixedly connected to a rotating shaft 11. A fixing frame 9 is fixedly connected to the outer wall of the housing 1. The end of the rotating shaft 11 away from the motor 8 is fixedly connected to the inner side wall of the fixing frame 9. A first gear 10 is fixedly sleeved on the side wall of the rotating shaft 11. A second gear 17 is fixedly sleeved on the side wall of the first rotating tube 18. The first gear 10 and the second gear 17 mesh.

[0030] The filter chamber 26 is equipped with a dust removal mechanism close to the filter cylinder 7. The dust removal mechanism includes a vibrating rod 30 disposed inside the filter chamber 26. A protrusion 31 is fixed to the side wall of the vibrating rod 30, and the protrusion 31 contacts the filter cylinder 7. Slide grooves 28 are provided on opposite side walls of the filter chamber 26. The two ends of the vibrating rod 30 slide within the two slide grooves 28 respectively. Two guide rods 34 pass through the vibrating rod 30 and are slidably connected to it. The two guide rods 34 are located inside the two slide grooves 28 respectively, and both ends of the guide rods 34 are fixed to the inner wall of the slide grooves 28. Springs 35 are fitted onto the guide rods 34. One end of the spring 35 is fixed to the inner wall of the slide groove 28, and the other end of the spring 35 is fixed to the vibrating rod 30. A first magnetic block 32 is fixed on the side wall of the vibrating rod 30. A rotating rod 15 is provided on one side of the vibrating rod 30. Both ends of the rotating rod 15 penetrate the inner wall of the filter chamber 26 and extend to the outside of the housing 1. The rotating rod 15 is rotatably connected to the inner wall of the filter chamber 26 through a bearing. A second magnetic block 33 that cooperates with the first magnetic block 32 is fixed in the middle of the side wall of the rotating rod 15. The rotating rod 15 drives the second magnetic block 33 to rotate and periodically attracts the first magnetic block 32 on the vibrating rod 30. With the reset action provided by the spring 35, the vibrating rod 30 can slide back and forth along the slide groove 28.

[0031] The ash removal mechanism and the rotating mechanism are connected by a transmission mechanism, which includes a first synchronous pulley 12 and a second synchronous pulley 14. The first synchronous pulley 12 is fixedly sleeved on the rotating shaft 11, and the second synchronous pulley 14 is fixedly sleeved on the rotating rod 15. A synchronous belt 13 is fitted between the first synchronous pulley 12 and the second synchronous pulley 14. The filter cylinder 7 is equipped with a back-blowing mechanism, which includes a back-blowing hood 29 disposed inside the filter cylinder 7. The back-blowing hood 29 fits against the inner wall of the filter cylinder 7. A connecting pipe 24 is connected to the side wall of the back-blowing hood 29, and the connecting pipe 24 passes through a second rotating pipe 25. A piston is fixed on the side wall of the housing 1. The piston cylinder 21 has an outlet pipe 22 and an intake pipe 23 connected to its side wall. Both the outlet pipe 22 and the intake pipe 23 are equipped with one-way valves. The end of the outlet pipe 22 away from the piston cylinder 21 is connected to the connecting pipe 24. The piston cylinder 21 has a piston inside. A connecting rod 20 is rotatably connected to the piston. A turntable 19 is fixedly sleeved on the side wall of the rotating rod 15. The end of the connecting rod 20 away from the piston is rotatably connected to the edge of the side wall of the turntable 19. The back-blowing mechanism is connected to the dust removal mechanism. When the rotating rod 15 rotates, it can drive the turntable 19 to rotate. The piston inside the piston cylinder 21 is driven to reciprocate through the connecting rod 20.

[0032] When using this invention, the exhaust fan 2 is started, and the dusty air from the outside enters the filter chamber 26 through the air inlet 5. The airflow is evenly distributed by the guide plate 6. When the dusty air passes through the filter cylinder 7, the dust is trapped on the outer surface of the filter cylinder 7. Then, the motor 8 is started to drive the first gear 10 to rotate through the rotating shaft 11, which drives the second gear 17 and the first rotating tube 18 to rotate. The first rotating tube 18 drives the filter cylinder 7 to rotate, so that the filter cylinder 7 rotates at a set speed. The purified air passes through the first rotating tube 18 → exhaust pipe 4 → exhaust fan 2 → air outlet chamber 27, and is finally discharged from the air outlet hood 3.

[0033] Meanwhile, the first synchronous pulley 12 can be driven to rotate through the rotating shaft 11. Through the transmission of the first synchronous pulley 12, the synchronous belt 13, and the second synchronous pulley 14, the rotating rod 15 can be driven to rotate synchronously. The rotating rod 15 drives the second magnetic block 33 to rotate, and periodically attracts the first magnetic block 32 on the vibrating rod 30. With the reset action provided by the spring 35, the vibrating rod 30 can slide back and forth along the slide groove 28. The protrusion 31 of the vibrating rod 30 continuously strikes the outer wall of the filter cylinder 7. Combined with the centrifugal force of the rotation of the filter cylinder 7 itself, the attached dust is removed.

[0034] Furthermore, as the rotating rod 15 rotates, it can drive the turntable 19 to rotate, and drive the piston in the piston cylinder 21 to reciprocate through the connecting rod 20. When the piston reciprocates, it can draw in air through the suction pipe 23 and exhaust air through the exhaust pipe 22. Through the connecting pipe 24 and the backflush hood 29, a reverse airflow is formed to impact the inner wall of the filter cylinder 7, further removing the dust embedded in the filter screen and achieving efficient self-cleaning. The dust is finally concentrated at the bottom of the filter chamber 26.

[0035] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
