Description

Technical Field

[0001] This application relates to the field of air purification, and more specifically, to an air purification device for enclosed spaces. Background Technology

[0002] As living standards improve, people have higher requirements for the environmental quality of office environments and other public places, so devices for indoor air purification are emerging one after another. For example, in a closed office workshop, a lot of dust is generated due to work; and long-term exposure to this environment can have a negative impact on the health of employees.

[0003] Existing air purification devices all have filters for dust purification, but they need to be removed and cleaned periodically; this operation is rather cumbersome. Therefore, there is reason to design an air purification device for enclosed spaces that can automatically clean the filter to improve the purification effect. Summary of the Invention

[0006] The air duct, located inside the housing, is constructed as an air guide channel connecting the air inlet and the air outlet;

[0007] Air purification equipment for enclosed spaces also includes:

[0008] Two wind deflectors are installed at both ends of the air duct;

[0009] The filter assembly is located inside the air duct and connected to two baffles to filter dust from the air.

[0010] The cleaning component is slidably installed in the air guide channel and partially connected to the filter component;

[0012] The cleaning component includes a cleaning plate that is slidably disposed in the air guide channel and a cleaning ring disposed on the cleaning plate and connected to the filter component;

[0013] During operation, the self-cleaning component cleans the filter components, thereby improving the air purification effect. Specifically, during the purification process, since the cleaning ring is always in contact with the filter components, moving the cleaning plate allows the cleaning ring to clean the filter components in real time, thus cleaning the filter components and further improving the purification effect.

[0014] Furthermore, a guide groove is formed through the inner part of the air duct near the water tank to guide the cleaning plate to move along the axis of the air duct;

[0015] A connecting block that slides within the guide groove and is fixed to the cleaning ring;

[0016] A water inlet hole is formed on the surface of the connecting block, extending into the interior of the cleaning ring.

[0021] The cleaning ring has cleaning cotton that comes into contact with the filter assembly.

[0022] Furthermore, a water-flowing chamber is formed inside the cleaning ring;

[0024] A filter plate connected to the cleaning surface is fixedly installed on the inner wall of the water flow chamber, and the surface of the filter plate has slag removal holes with a mesh size larger than the filter holes.

[0025] Furthermore, the filtering component includes:

[0026] The rotating rod connects two wind deflectors and is located inside the air duct;

[0027] A filter screen, wrapped around the surface of the rotating rod, is used to filter dust from the air;

[0028] An air guide plate is installed on the side wall of the rotating rod, located at the end of the filter screen;

[0029] The fan, which rotates inside the air duct, is used to draw in air.

[0030] The surface of the rotating rod is formed into a guide section to direct the airflow in a spiral pattern on the filter screen surface.

[0031] Furthermore, the baffle plate near the air inlet is defined as the first baffle plate;

[0032] Position the baffle plate furthest from the air inlet as the second baffle plate;

[0033] One end of the rotating rod is rotatably connected to the surface of the first baffle plate located inside the air duct;

[0034] The surface of the first baffle plate is partially perforated to form an air intake hole corresponding to the rotating rod, allowing air to enter the interior of the air duct.

[0035] The air intake holes are arranged in a ring along the circumference of the rotating rod;

[0036] Within this, on the same plane, there is a gap between the inner wall of the air intake hole and the outer wall of the rotating rod.

[0037] Furthermore, the air guide is recessed on the surface of the rotating rod, and the recessed part extends along the axial direction of the rotating rod and rotates at a certain angle along the circumference of the rotating rod during the extension process.

[0038] Several air guide sections are provided and evenly distributed along the circumference of the rotating rod.

[0039] Furthermore, the surface of the air guide plate near the air inlet forms an air guide surface, which is arc-shaped;

[0040] The surface of the air guide surface is perforated to form air leakage holes.

[0041] Furthermore, one end of the rotating rod is rotatably mounted on the second wind deflector;

[0042] The end portion of the rotating rod protrudes from the surface of the second baffle.

[0043] The portion of the rotating rod protruding from the surface of the second baffle plate is connected to the fan via a drive structure, so that the fan drives the rotating rod to rotate.

[0044] Furthermore, the drive structure includes a fixed gear disposed on the portion of the rotating rod protruding from the surface of the second baffle plate; a gear ring disposed on the surface of the second baffle plate and meshing with the fixed gear; and a connecting rod connecting the gear ring and the central shaft on the fan.

[0068] It should also be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings. Unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other.

[0069] It should be noted that the concepts of "first" and "second" mentioned in this disclosure are used only to distinguish different devices, modules or units, and are not used to limit the order of functions performed by these devices, modules or units or their interdependencies.

[0070] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0071] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0072] Reference Figure 1-11An air purification device for a closed space includes: a housing 1, a fan duct 2, a baffle plate, a filter assembly 3, a cleaning assembly 6, and a water tank 5;

[0073] The housing 1 is rectangular, with a bracket on its surface for hanging the housing 1 on a wall, thus allowing the device to be hung on the wall; the housing 1 is configured to have an air inlet a1 and an air outlet a11 entering the housing 1; an air duct 2 is provided inside the housing 1, which is configured to have an air guide channel a2 connecting the air inlet a1 and the air outlet a11, and two wind baffles are provided at both ends of the air duct 2; preferably, a filter assembly 3 is provided inside the air guide channel a2 to connect the two wind baffles for filtering dust in the air;

[0074] Specifically, the filter assembly 3 includes: a rotating rod 31, a filter screen 32, an air guide plate 33, and a fan 34;

[0075] The baffle plate near the air inlet a1 is defined as the first baffle plate 21, and the baffle plate away from the air inlet a1 is positioned as the second baffle plate 22. One end of the rotating rod 31 is rotatably connected to the surface of the first baffle plate 21 located inside the air duct 2. A portion of the surface of the first baffle plate 21 is formed to create an air inlet hole a21 corresponding to the rotating rod 31, allowing air to enter the air duct 2. The air inlet hole a21 is distributed in a ring along the circumference of the rotating rod 31. In the same plane, there is a gap between the inner wall of the air inlet hole a21 and the outer wall of the rotating rod 31. A fan 34 is rotatably installed at the end of the air duct 2 away from the first baffle plate 21. The fan 34 is driven by a motor to create a negative pressure inside the air duct 2, and begins to draw air in from the air inlet hole a21. The air entering through the air inlet hole a21 is thus arranged to flow along the rotating rod 31.

[0076] More specifically, the filter screen 32 is wrapped around the surface of the rotating rod 31; preferably, the surface of the rotating rod 31 forms an air guide portion a3 for guiding the air to flow in a spiral shape on the surface of the filter screen 32; the air guide portion a3 is partially concave on the surface of the rotating rod 31, and the concave portion extends along the axial direction of the rotating rod 31 and rotates at a certain angle along the circumference of the rotating rod 31 during the extension process; wherein, several air guide portions a3 are provided and are evenly distributed along the circumference of the rotating rod 31; with this arrangement, after the air enters from the air intake hole, it will flow along the extension direction of the air guide portion a3 and adhere to the filter screen 32 in a spiral direction on the surface of the filter screen 32, thereby increasing the contact area between the air and the filter screen 32 and improving the filtration effect.

[0077] More specifically, the rotating rod 31 is provided with an air guide plate 33. The surface of the air guide plate 33 near the air inlet a21 forms an air guide surface, which is arc-shaped. A leakage hole a33 is formed through the surface of the air guide surface. With this arrangement, when the air is filtered, it will flow to the air guide surface. Then, part of the air will be discharged through the leakage hole a33, and the other part will flow out along the extension trajectory of the air guide surface. This can disperse the air flow and prevent the air from gathering together, so that the purified air is more evenly dispersed.

[0078] In another preferred embodiment, one end of the rotating rod 31 is rotatably mounted on the second baffle plate 22, and the end portion of the rotating rod 31 protrudes from the surface of the second baffle plate 22; the fan 34 is rotatably mounted on the second baffle plate 22, and the second baffle plate 22 has a plurality of wind holes a22; the portion of the rotating rod 31 protruding from the surface of the second baffle plate 22 is connected to the fan 34 through a drive structure, so that the fan 34 drives the rotating rod 31 to rotate.

[0079] More specifically, the drive structure includes a fixed gear 4 disposed on the portion of the rotating rod 31 that protrudes from the surface of the second baffle plate 22; a gear ring 41 disposed on the surface of the second baffle plate 22 that meshes with the fixed gear 4; and a connecting rod 42 connecting the gear ring 41 and the central shaft on the fan 34. With this configuration, when the fan 34 rotates, it drives the gear ring 41 to rotate through the connecting rod 42, which in turn drives several fixed gears 4 to rotate. This allows each rotating rod 31 to rotate independently, thus enabling the air inside the air duct 2 to come into contact with the filter screen and improving the filtration effect.

[0080] A cleaning component 6 for cleaning the filter screen 32 is slidably disposed within the air guide channel a2. Specifically, a water tank 5 for storing cleaning water is disposed on the housing 1. The cleaning component 6 includes a cleaning plate 61 slidably disposed within the air guide channel a2 and a cleaning ring 62 disposed on the cleaning plate 61 that partially abuts against the filter screen 32. A cleaning chamber a61 for water supply is formed inside the cleaning plate, and the cleaning ring is rotatably disposed on the inner wall of the cleaning chamber a61. Louvers 65 are arranged along the annular extension direction of the cleaning chamber a61 on the inner wall of the cleaning chamber a61. The cleaning plate is movably disposed on the inner wall of the air guide channel a2. Preferably, the cleaning plate is driven to reciprocate by a driver. The driver that drives the cleaning plate to reciprocate can be an electric telescopic rod, a cylinder, or other mechanical components. The type of driver is not limited and is existing technology, so it will not be described in detail in this embodiment.

[0081] More specifically, the air duct 2 forms an air guide channel a2 near the inner wall of the water tank 5, forming a guide groove a23 for guiding the cleaning plate 61 to move along the axis of the air duct 2. A connecting block 611 fixed to the cleaning plate 61 is slidably disposed in the guide groove a23. The surface of the connecting block 611 extends into the interior of the cleaning plate 61 to form a water inlet hole a61. A water pipe 612 is provided on the water tank 5 to connect with the water inlet hole a61 so that water in the water tank 5 can enter the cleaning chamber a61. Preferably, the connecting block 611 is connected to the side wall of the guide groove a23 by a folding plate 613 to seal the guide groove a23. In this way, the connecting block 611 can prevent air in the air duct a2 from leaking out of the guide groove a23 when the guide groove a23 moves.

[0082] More specifically, a cleaning groove a62 is formed on the surface of the cleaning plate for the rotating shaft to pass through. The cleaning ring is rotatably mounted on the inner wall of the cleaning chamber a61, and the axis of the cleaning ring is collinear with the axis of the cleaning groove a62. A cleaning cotton 621 is fixed in the inner ring of the cleaning ring and contacts the filter screen 32. The cleaning cotton 621 is used to brush the dust off the surface of the filter screen 32.

[0083] Preferably, the cleaning ring protrudes to form a mating block 622 and is inserted into the air guide section a3; when the cleaning plate moves along the guide groove a23, the mating block 622 moves along the extension direction of the air guide section a3, thereby driving the cleaning ring to rotate, thus improving the cleaning capacity; more specifically, a rotating groove a31 into which the mating block 622 is embedded is formed at the end of the air guide section a3, the rotating groove a31 extends around the circumference of the rotating rod 31 and docks with the air guide section a3, and the docking part forms a chamfer; thus, in the initial state, the mating block 622 is embedded in the rotating groove a31 and does not affect the rotation of the rotating rod 31.

[0084] More specifically, a water-supplying flow chamber a621 is formed inside the cleaning ring; the outer wall of the cleaning ring extends into the flow chamber a621, forming a plurality of filter holes a622; a filter plate a623 connected to the cleaning surface is fixedly provided on the inner wall of the flow chamber a621, and the surface of the filter plate a623 has slag-removing holes a624 with a mesh size larger than that of the filter holes a622; the surface of the cleaning chamber a61 forms the filter plate a623, and the filter plate a623 is evenly laid along the circumference of the cleaning chamber a61; preferably, one side of the filter plate a623 is fixedly provided on a surface with a filter plate a624 connected to the cleaning surface. The filter plate a623 is located on the inner wall of the water flow chamber a621 with filter holes a622 and is positioned between two adjacent rows of filter holes a622. The other side of the filter plate a623 is fixedly connected to the cleaning surface. The surface extension direction of the filter plate a623 is inclined to the diameter direction of the cleaning ring. This arrangement allows for water filtration, thus enabling the water to be filtered before cleaning the filter screen 32, improving the cleaning effect. Furthermore, the rotation of the cleaning ring during cleaning generates centrifugal force, causing the water in the inner water flow chamber a621 to be thrown onto the filter plate a623.

[0085] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
