Description

Technical Field

[0001] This invention relates to the field of air purifier technology, and in particular to a multifunctional air purifier. Background Technology

[0002] Air purifiers, also known as "air cleaners" or "air fresheners," are products that can adsorb, decompose, or transform various air pollutants (generally including dust, pollen, odors, bacteria, allergens, and indoor air pollution such as formaldehyde), effectively improving air cleanliness. They are mainly household and commercial air purifiers used to remove indoor air pollution.

[0003] Air purifiers are widely used in indoor environmental management, but traditional equipment has significant drawbacks: their filters are fixed, causing airflow to concentrate only through a local area of ​​the filter, resulting in reduced filtration efficiency; and existing technology lacks an automatic cleaning mechanism, requiring users to frequently disassemble and reassemble the filter for manual cleaning (an average of 2-3 times per month), which is complicated and easily damages the snap-fit ​​structure. Summary of the Invention

A second synchronous belt is sleeved on the outer side of both sets of second synchronous pulleys.

[0008] Preferably, two sets of fixed seats are fixedly installed on the upper side of the square frame near the lower side of the roller rod. A round tube is fixedly installed at one end of each of the two sets of fixed seats. A second gear is movably installed between the two sets of round tubes. A transmission rod is fixedly installed on the inner side of the second gear. A transmission roller is fixedly installed on the outer side of the transmission rod near the inner side of each of the two sets of round tubes. Six sets of movable grooves are opened on the inner side of each of the six sets of movable grooves. A sealing push plate is slidably installed on the inner side of each of the six sets of movable grooves. A spring is fixedly installed between each of the six sets of sealing push plates and the inner wall of each of the six sets of movable grooves. An air inlet is provided at the inclined position on the lower side of the round tube, and an air outlet is provided at the inclined position on the upper side of the round tube.

[0009] Preferably, the T-shaped fixing strip is adapted to the T-shaped groove, the sealing plate is adapted to the outer side of the square frame for locking, and the square frame is provided with arc-shaped strips near the four sets of roller rods to fit against the outer side of the filter screen. The four sets of roller rods are located between the racks.

[0010] Preferably, the filter screen and rack are made of soft material. The rack is respectively engaged with two sets of first gears near the front and rear sides. The cover plate and square frame are positioned and pressed inside the air purifier body by the upper shell cover. Two sets of handles are fixedly installed on the upper side of the cover plate.

[0011] Preferably, the two sets of collection shells are respectively fitted and adapted to the two sides of the square frame, the fixing plate on the upper side of the collection shell is fixedly connected to the square frame by bolts, and the cleaning brush cylinder is fitted to the filter screen.

[0012] Preferably, the second gear meshes with the middle set of first gears, the transmission rod is movably disposed inside the two sets of circular tubes, and the transmission rod and transmission roller are eccentrically disposed inside the circular tubes towards the air outlet.

[0013] Preferably, the six sets of sealing push plates are respectively attached to the inner wall of the circular tube, the six sets of springs are in different compression states, and the air outlet is tilted towards the set of dust inlets that are not equipped with cleaning brushes.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. When the air purifier is started, the outside airflow enters through the air inlet, is filtered by the filter, and then blows out through the air outlet. The square frame slides on the outside of the four sets of T-shaped fixing strips through the T-slots. Together with the sealing plate, filter, and collection shell, it is sealed on the side of the air inlet, so that the filter can effectively filter the incoming airflow. The first motor drives the first synchronous wheel to rotate, which in turn drives another set of first synchronous wheels and roller rods to rotate. The rotating roller rod drives the first gear to drive the rack and pinion to rotate. The use of the rotating filter allows the airflow to penetrate the entire filter surface evenly, which can delay local saturation.

[0016] 2. The first gear in the middle of the rotating roller rod drives the second gear to rotate. The rotating second gear drives the transmission rod and the transmission rollers in the two sets of circular tubes to rotate together. The two sets of rotating transmission rollers drive the six sets of sealing push plates set on the inner side to rotate. Under the action of elastic springs, the six sets of sealing push plates keep the sealing push plates in contact with the inner wall of the circular tube. After the airflow passes through the air inlet, it is pushed to the air outlet. During this process, because the transmission rod and transmission roller are set in an eccentric position, the space between the two sets of sealing push plates changes from large to small, squeezing the airflow that enters inside. When it moves to the air outlet, the squeezed airflow is accelerated and blown out from the air outlet, back-blowing from the inside of the filter screen, causing the dust on the outside of the filter screen to be blown off. With the help of a corresponding set of collection shells, the dust is collected and processed. When the filter screen is rotated, the deep dust embedded in the filter screen is also peeled off, effectively cleaning it and extending the replacement cycle.

[0017] 3. The second synchronous pulley is driven by the second motor to rotate, and the second synchronous belt drives another set of second synchronous pulleys and the round rod to rotate. The rotating round rod drives the cleaning brush cylinder to rotate, and the cleaning brush cylinder rotates in the opposite direction to the filter screen to perform multi-functional cleaning. It brushes away stubborn dust or impurities on the surface of the filter screen that are not easy to blow off, and collects or loosens them in the collection shell through the dust inlet. When it rotates to the position of another set of collection shells, it works with the back-blowing component to blow the dust and impurities into the other set of collection shells for collection, further improving the cleaning effect and reducing the maintenance cycle.

[0031] T-shaped fixing strip 51 is adapted to T-shaped groove 54, sealing plate 52 is adapted to the outer side of square frame 53 and engages with it. Arc-shaped strips are provided around the four sets of roller rods 55 and fit against the outer side of filter screen 56. The four sets of roller rods 55 are located between racks 57. Filter screen 56 and racks 57 are made of soft material. Racks 57 are respectively engaged with two sets of first gears 59 near the front and rear sides. Cover plate 510 and square frame 53 are positioned and pressed by upper shell cover 4 inside air purifier body 1. Two sets of handles are fixedly provided on the upper side of cover plate 510.

[0032] When the air purifier body 1 is started, the outside airflow enters through the air inlet 2, is filtered by the filter screen 56, and is then blown out through the air outlet 3. The square frame 53 slides on the outside of the four sets of T-shaped fixing strips 51 through the T-shaped groove 54, and is sealed on one side of the air inlet 2 in conjunction with the sealing plate 52, the filter screen 56, and the collection shell 61, so that the filter screen 56 can effectively filter the incoming airflow. The first motor 511 drives the connected first synchronous wheel 512 to rotate, and 513 drives another set of first synchronous wheels 512 and roller rod 55 to rotate. The rotating roller rod 55 drives the first gear 59 to drive the rack 57 and filter screen 56 to rotate. The use of the rotating filter screen 56 makes the airflow penetrate the entire filter surface evenly, which can delay local saturation.

[0033] The collection assembly 6 includes collection shells 61 located on the upper side of the square frame 53 near both sides. Two sets of fixing plates 62 are fixedly installed on the upper end of each set of collection shells 61. Dust inlets 63 are opened on the lower side of each set of collection shells 61 corresponding to the position of the filter screen 56. A round rod 64 is rotatably installed on the inner side of one of the sets of collection shells 61 near the dust inlet 63. A cleaning brush cylinder 65 is fixedly installed on the outer side of the round rod 64. A second motor 66 is fixedly installed on the upper inner wall of the collection shell 61. A second synchronous pulley 67 is fixedly installed on both the rotating shaft of the second motor 66 and the outer side of the round rod 64. A second synchronous belt 68 is sleeved on the outer side of the two sets of second synchronous pulleys 67.

[0034] Two sets of collection shells 61 are respectively fitted and matched with the two sides of the square frame 53. The fixing plate 62 on the upper side of the collection shell 61 is fixedly connected to the square frame 53 by bolts. The cleaning brush cylinder 65 is fitted and set with the filter screen 56.

[0035] The second motor 66 drives the connected second synchronous pulley 67 to rotate, and the second synchronous belt 68 drives another set of second synchronous pulleys 67 and round rod 64 to rotate. The rotating round rod 64 drives the cleaning brush cylinder 65 to rotate, and the cleaning brush cylinder 65 rotates in the opposite direction to the filter screen 56 to perform multi-functional cleaning. It brushes away stubborn dust or impurities on the surface of the filter screen 56 that are not easy to blow off, and collects or loosens them in the collection shell 61 through the dust inlet 63. When it rotates to the position of the other set of collection shells 61, it works with the back-blowing component 7 to blow the dust and impurities into the other set of collection shells 61 for collection, further improving the cleaning effect and reducing the maintenance cycle.

[0036] Two sets of fixed seats 71 are fixedly installed on the upper side of the square frame 53 near the lower side of the roller rod 55. A round tube 72 is fixedly installed at one end of each set of fixed seats 71. A second gear 73 is movably installed between the two sets of round tubes 72. A transmission rod 74 is fixedly installed on the inner side of the second gear 73. A transmission roller 75 is fixedly installed on the outer side of the transmission rod 74 near the inner side of each set of round tubes 72. Six sets of movable grooves 76 are opened on the inner side of each set of movable grooves 76. A sealing push plate 77 is slidably installed on the inner side of each set of movable grooves 76. A spring 78 is fixedly installed between each set of sealing push plates 77 and the inner wall of each set of movable grooves 76. An air inlet 79 is installed at the lower inclined position of the round tube 72, and an air outlet 710 is installed at the upper inclined position of the round tube 72.

[0037] The second gear 73 meshes with the middle set of first gears 59. The transmission rod 74 is movably disposed inside the two sets of circular tubes 72. The transmission rod 74 and the transmission roller 75 are eccentrically disposed inside the circular tubes 72, close to the air outlet 710. The six sets of sealing push plates 77 are respectively attached to the inner wall of the circular tubes 72. The six sets of springs 78 are in different compression states. The air outlet 710 is tilted towards a set of dust inlets 63 that are not equipped with cleaning brush cylinders 65.

[0038] The first gear 59 in the middle of the rotating roller rod 55 drives the second gear 73 to rotate. The rotating second gear 73 drives the transmission rod 74 and the transmission rollers 75 in the two sets of circular tubes 72 to rotate together. The two sets of rotating transmission rollers 75 drive the six sets of sealing push plates 77 arranged on the inner side to rotate. Under the action of the elastic spring 78, the six sets of sealing push plates 77 are kept in contact with the inner wall of the circular tube 72. After the airflow passes through the air inlet 79, it is pushed to the position of the air outlet 710. During the process, because the transmission rod 74 and transmission roller 75 are set in an eccentric position, the space between the two sets of sealing push plates 77 decreases from large to small, squeezing the airflow that enters inside. When the airflow moves to the air outlet 710, the squeezed airflow is accelerated and blown out from the air outlet 710, and back-blowing from the inside of the filter screen 56, causing the dust on the outside of the filter screen 56 to be blown off. In conjunction with the corresponding set of collection shells 61, the dust is collected and processed. When the filter screen 56 is rotated, the deep dust embedded in the filter screen is also peeled off, effectively cleaning it and extending the replacement cycle.

[0039] Working principle: When in use, the air purifier body 1 is started. The outside airflow enters through the air inlet 2, is filtered by the filter screen 56, and then blown out through the air outlet 3. The square frame 53 slides on the outside of the four sets of T-shaped fixing strips 51 through the T-slots 54. Together with the sealing plate 52, filter screen 56, and collection shell 61, it is sealed on one side of the air inlet 2, so that the filter screen 56 can effectively filter the incoming airflow. The first motor 511 drives the connected first synchronous wheel 512 to rotate. The motor 513 drives another set of first synchronous wheels 512 and roller rod 55 to rotate. The rotating roller rod 55 drives the first gear 59 to drive the gear teeth. The filter 57 rotates with the filter screen 56. The rotating filter screen 56 ensures that the airflow penetrates the entire filter surface evenly, delaying local saturation. Additionally, the first gear 59 in the middle of the rotating roller rod 55 drives the second gear 73 to rotate. The rotating second gear 73 drives the transmission rod 74 and the transmission rollers 75 in the two sets of circular tubes 72 to rotate together. The two sets of rotating transmission rollers 75 respectively drive the six sets of sealing push plates 77 arranged on the inner side to rotate. Under the action of the elastic spring 78, the six sets of sealing push plates 77 are kept in contact with the inner wall of the circular tube 72. After the airflow passes through the air inlet 79... The filter is pushed towards the air outlet 710. During this process, because the transmission rod 74 and transmission roller 75 are eccentrically positioned, the space between the two sets of sealing push plates 77 decreases, compressing the airflow entering from inside. When it moves to the air outlet 710, the compressed airflow is accelerated and blown out from the air outlet 710, back-blowing from the inside of the filter screen 56, causing the dust on the outside of the filter screen 56 to be blown off. This is then collected and processed by a corresponding set of collection shells 61. When the filter screen 56 is rotated, the deep-seated dust in the filter screen is also peeled off, effectively cleaning it and extending the replacement cycle. The second synchronous pulley is driven by the second motor 66. The second synchronous belt 68 drives another set of second synchronous pulleys 67 and round rods 64 to rotate. The rotating round rods 64 drive the cleaning brush cylinder 65 to rotate. The cleaning brush cylinder 65 rotates in the opposite direction to the filter screen 56 to perform multi-functional cleaning. It brushes away stubborn dust or impurities that are not easily blown off from the surface of the filter screen 56. The dust is collected or loosened in the collection shell 61 through the dust inlet 63. When it rotates to the position of another set of collection shells 61, it works with the back-blowing component 7 to blow the dust and impurities into the other set of collection shells 61 for collection, further improving the cleaning effect and reducing the maintenance cycle.
