Description

Technical Field

[0001] This utility model belongs to the field of air purification technology, specifically relating to a dust-free indoor air purification device. Background Technology

[0002] A cleanroom is a room equipped with air filtration, distribution, optimization, construction materials, and devices. Specific operating procedures are used to control the concentration of airborne particulate matter to achieve an appropriate level of particulate cleanliness. Cleanrooms require air purification devices to filter and purify the incoming air.

[0003] When existing air purifiers filter dust from the air, the dust gradually adheres to the filter screen, and some dust becomes embedded in the filter pores. Because dust is sticky and the space inside the filter pores is relatively enclosed, this embedded dust is difficult to clean, thus affecting the air purifier's subsequent air filtration and purification capabilities.

[0004] Therefore, a dust-free indoor air purification device is proposed. Utility Model Content

[0005] This invention provides a dust-free indoor air purification device, the purpose of which is to solve the problems mentioned above.

[0006] This utility model provides a cleanroom air purification device, including an air purification body; a dust filter assembly disposed on the outer wall of the air purification body; and a dust shaking assembly disposed on the inner wall of the dust filter assembly. The dust filter assembly includes: a fixed frame fixed to one side of the outer wall of the air purification body; fixed platforms respectively fixed to the top and bottom of the fixed frame; a vertical rope fixed between the two fixed platforms; an electric push rod fixed to one side of the outer wall of the fixed frame; a movable platform fixed to the output end of the electric push rod; two rotating disks rotatable on one side of the outer wall of the movable platform; and two horizontal ropes, horizontal rope one and horizontal rope two, respectively fixed to the center of the outer walls of the two rotating disks, with horizontal rope one located on one side of the vertical rope and horizontal rope two located on the other side of the vertical rope. The dust shaking assembly includes: a control box fixed to the inner wall of the fixed frame, with the other ends of horizontal rope one and horizontal rope two located inside the control box.

[0007] Furthermore, the dust shaking assembly also includes a servo motor fixed to the inner wall of the control box; a drive gear fixed to the output end of the servo motor; and driven gear one and driven gear two rotating on the inner wall of the control box. The center of the outer wall of driven gear one is fixed to one end of horizontal rope one, and the center of the outer wall of driven gear two is fixed to one end of horizontal rope two.

[0008] Furthermore, the top of the air purifier body is provided with a dust back-blowing assembly; the dust back-blowing assembly includes a back-blowing fan fixed to the top of the air purifier body; and a back-blowing nozzle fixed to the inner wall of the air purifier body.

[0009] Furthermore, the driving gear and the driven gear two are connected to the driven gear one through gear meshing;

[0010] By adopting the above technical solution, power is transmitted through meshing connection, so that when the driving gear rotates, the driven gear two and the driven gear one rotate synchronously.

[0011] Furthermore, the inner wall of the fixed frame is provided with a groove for housing the movable platform, and the outer wall of the movable platform is provided with a through slot for the fixed platform to be inserted.

[0012] By adopting the above technical solution, the grooves and through slots ensure smooth movement of the moving platform and prevent obstruction of its movement.

[0013] Furthermore, the vertical rope, horizontal rope one, and horizontal rope two form a filter mesh layer structure with rectangular filter holes, and the vertical rope, horizontal rope one, and horizontal rope two are all made of high-strength synthetic fiber rope.

[0014] By adopting the above technical solution, the filter mesh structure can filter dust in the air, giving it filtering ability. The vertical rope, horizontal rope one, and horizontal rope two are made of high-strength synthetic fiber rope, which can give them high strength and low elasticity.

[0015] Furthermore, a gas flow channel is provided inside the air purifier body near the back blower and the back blow nozzle, and an exhaust fan and a filling layer for air purification are provided inside the air purifier body.

[0016] By adopting the above technical solution, air is drawn into the gas flow channel by the operation of the back blower, and the air is blown towards the dust filter component through the back blow nozzle. The filling layer can filter, adsorb and purify the air.

[0017] The beneficial effects of this utility model are as follows:

[0018] This invention allows for the control of the relative movement of the moving platform, enabling the adjustment of the filter mesh layer structure (comprising horizontal rope one, horizontal rope two, and vertical rope) to maintain a loose or tight state. This control over the size of the filter pores facilitates the cleaning of dust embedded within them. Applying rotational force to the loose horizontal rope one and horizontal rope two, along with centrifugal force and vibration generated by impacting the vertical rope, causes dust adhering to the outer walls of the horizontal rope one, horizontal rope two, and vertical rope to detach, achieving self-cleaning of the filter mesh layer structure. This ensures that the dust within the filter pores is thoroughly cleaned, guaranteeing the air purifier's subsequent air filtration and purification capabilities.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Reference Figure 1-6 This utility model embodiment proposes a cleanroom air purification device, including an air purification body 1. A fixed frame 21 for a dust filter assembly 2 is provided on one outer wall of the air purification body 1. Fixed platforms 22 are provided at the top and bottom of the fixed frame 21. Several vertical ropes 23 are equally spaced between the two fixed platforms 22. Two electric push rods 24 are symmetrically arranged on one outer wall of the fixed frame 21. The two electric push rods 24 are fixedly connected to a moving platform 25 through their output ends. A groove is provided on the inner side wall of the fixed frame 21 for the moving platform 25 to be received. A through groove is provided on the outer side wall of the moving platform 25 for the fixed platform 22 to be inserted. The groove and through groove ensure smooth movement of the moving platform 25 and prevent obstruction of movement. The side of the moving platform 25 away from the output end of the electric push rod 24... Several sets of rotating disks 26 are equidistantly rotating on the outer wall. Each set of rotating disks 26 consists of two disks. Horizontal rope 1 27 and horizontal rope 28 are respectively set at the center of one side of the outer wall of the two rotating disks 26. Horizontal rope 1 27 is located above and to the side of horizontal rope 28. Vertical rope 23, horizontal rope 1 27 and horizontal rope 28 form a filter mesh layer structure with rectangular filter holes. The filter mesh layer structure can filter dust in the air, giving it filtering ability. Vertical rope 23, horizontal rope 1 27 and horizontal rope 28 are all made of high-strength synthetic fiber rope, such as nylon rope and polypropylene rope, which have high strength and low elasticity. This avoids the vertical rope 23, horizontal rope 1 27 and horizontal rope 28 from deforming when pulled, which would cause the rectangular filter holes on the filter mesh layer structure to become larger, thus ensuring the filtering effect of the filter mesh layer structure on small dust particles.

[0030] A control box 31 for the dust shaking assembly 3 is installed on one inner wall of the fixed frame 21 at a position opposite to the moving platform 25. A servo motor 32 is installed on one inner wall of the control box 31. The servo motor 32 is fixedly connected to the drive gear 33 through its output end. Several gear sets are rotatably connected on one inner wall of the control box 31. The gear sets consist of driven gear 1 34 and driven gear 2 35. The drive gear 33 and driven gear 2 35 are connected to driven gear 1 34 through gear meshing. Power is transmitted through meshing, so that when the drive gear 33 rotates, driven gear 2 35 and driven gear 1 34 rotate synchronously. The center of one outer wall of driven gear 1 34 is fixedly connected to one end of horizontal rope 1 27, and the center of one outer wall of driven gear 2 35 is fixedly connected to one end of horizontal rope 2 28.

[0031] The top of the air purifier body 1 is provided with a back-blowing fan 41 in the dust back-blowing assembly 4, and four back-blowing nozzles 42 are symmetrically arranged on the inner side wall of the air purifier body 1. A gas flow channel is provided inside the air purifier body 1 near the back-blowing fan 41 and the back-blowing nozzles 42. An exhaust fan and a filling layer for air purification are provided inside the air purifier body 1. The back-blowing fan 41 draws air into the gas flow channel and blows the air towards the dust filter assembly 2 through the back-blowing nozzles 42. The airflow in the opposite direction blows the dust shaken off from the vertical rope 23, horizontal rope 1 27 and horizontal rope 2 28 away from the air purifier body 1, preventing dust from entering the air purifier body 1. The back-blowing nozzles 42 face the dust filter assembly 2.

[0032] The specific implementation method is as follows: When filtering and purifying the air entering the cleanroom, the exhaust fan inside the air purification body 1 works, and the external air passes through the dust filter component 2 and enters the air purification body 1 under the action of negative pressure, and is filtered, adsorbed and purified by the adsorption of the filling layer.

[0033] When air passes through the dust filter assembly 2, it passes through the filter layer structure composed of vertical rope 23, horizontal rope one 27, and horizontal rope two 28. The rectangular filter holes in the filter layer structure intercept dust in the air, thus achieving air filtration. After the air purifier body 1 has been used for a period of time, the controller inside the air purifier body 1 controls the electric push rod 24 and the servo motor 32 to start. The electric push rod 24 drives the moving platform 25 to move through its output end on one side. The moving platform 25 moves towards the control box 31. The horizontal rope one 27 and horizontal rope two 28 between the moving platform 25 and the control box 31 are in a slack state. The horizontal rope one 27 and horizontal rope two 28 are in a slack state with the vertical rope. As the filter holes 23 enlarge, the servo motor 32 drives the drive gear 33 to rotate through its output end on one side. Under meshing transmission, the driven gear 1 34 and driven gear 2 35 rotate, which in turn pulls the horizontal rope 1 27 and horizontal rope 2 28 to rotate. Since the horizontal rope 1 27 and horizontal rope 2 28 are in a slack state, the high-speed rotation of the horizontal rope 1 27 and horizontal rope 2 28 will throw off the dust on the outer wall. The centrifugal force generated by the rotation causes the horizontal rope 1 27 and horizontal rope 2 28 to collide with the vertical rope 23. The vertical rope 23 vibrates after being impacted, and the vibration force is used to throw off the dust on its outer wall, thus cleaning the dust clogging the filter mesh structure.

[0034] When cleaning dust from the filter layer structure, the back air blower 41 draws air into the gas flow channel and blows the air towards the dust filter assembly 2 through the back air nozzle 42. The reverse airflow blows the dust shaken off from the vertical rope 23, horizontal rope 1 27 and horizontal rope 2 28 away from the air purification body 1, preventing dust from entering the air purification body 1.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
