Description

Technical Field

[0001] This utility model belongs to the field of filtration equipment technology, specifically relating to a filtration device and a dehumidifier. Background Technology

[0002] Dehumidifiers often incorporate a filter structure to remove impurities from the air. Over time, impurities accumulate on the filter screen, affecting the dehumidifier's normal operation. To address this issue, Chinese utility model patent CN215113194U discloses a filter structure for dehumidifiers. This structure includes a panel and a filter screen. The lower end of the panel houses an electric push rod, and the upper end of the electric push rod has a lifting rod. The outer surface of the filter screen has a cleaning plate, and the inner and outer surfaces of the cleaning plate have cleaning brushes. A mounting plate is located on the outer side of the filter screen, and a hanging ring is positioned at the top of the mounting plate. Mounting slots are located on both sides of the upper end of the panel, and lifting grooves are located on the outer sides of the mounting slots. A sliding strip is also located at the top of the panel. The dehumidifier uses a filter structure with the advantage of automatic cleaning, which can keep the filter screen clean. In actual use, the dust on the filter screen is cleaned by periodically raising the rod to drive the bristles. However, simply using the raising rod to drive the bristles to clean the filter screen cannot remove stubborn dust. In addition, the device requires manual activation of the cleaning device at regular intervals. It cannot clean while dehumidifying, which greatly increases the workload. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a filtration device and dehumidifier that enables the filter screen to rotate relative to the cleaning mechanism, allowing the cleaning mechanism to remove dust from the filter screen, thus avoiding filter screen clogging and effectively increasing the air intake of the dehumidifier.

[0004] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0005] A filtration device includes: a housing, a filter screen, a cleaning mechanism, and a drive mechanism;

[0006] The filter screen is rotatably connected to the housing;

[0009] The above technical solution enables the filter screen to rotate relative to the cleaning mechanism, allowing the cleaning mechanism to remove the dust on the filter screen, thus avoiding the problem of filter screen clogging and effectively increasing the air intake of the dehumidifier.

[0010] In conjunction with the first aspect, optionally, the opposite sides of the housing are provided with a first notch and a second notch respectively; the filter device further includes a ring, a cylinder and a toothed ring; in specific implementation, the cross-section of the first notch and the second notch is circular;

[0019] The above technical solution provides a specific structure for a cleaning mechanism. The shaft is fixedly connected to the cylinder through the shaft fixing member and is also connected to the bristle fixing member. Since the cleaning mechanism is in a stationary state, when the filter screen is driven to rotate by the driving mechanism, the filter screen and the cleaning mechanism generate relative motion, thereby realizing the cleaning mechanism to remove the dust on the filter screen.

[0021] The first fixing post is located inside the cylinder and is connected to the shaft;

[0022] One end of the first connecting rod is connected to the first fixed column, and the other end is connected to the cylinder.

[0023] The above technical solution provides a specific structure for the shaft fixing component, which uses the first connecting rod to fix the first fixing column inside the cylinder, thereby achieving the fixation of the cleaning mechanism.

[0024] In conjunction with the first aspect, the filtration device may optionally further include a second fixed column and a second connecting rod;

[0028] The above technical solution utilizes the cooperation of the second fixed column and the second connecting rod to support the shaft, thereby improving the structural stability of the filtration device in this utility model.

[0029] In conjunction with the first aspect, optionally, the toothed ring is rotatably connected to the ring and the cylinder via a first bearing ring and a second bearing ring, respectively.

[0030] The above technical solution utilizes a first bearing ring and a second bearing ring to achieve the separation of the toothed ring from the circular ring and the cylinder, and the toothed ring can rotate relative to the circular ring and the cylinder. The structure is simple and can ensure the rotation effect.

[0031] In conjunction with the first aspect, the driving mechanism may optionally include a drive motor and gears;

[0032] The gear is connected to the output end of the drive motor and also meshes with the gear ring.

[0033] The above technical solution provides a specific structure for the drive mechanism, which includes a drive motor and gears. The structure is simple, and all components can be directly purchased from the market, thereby effectively reducing production costs.

[0034] In conjunction with the first aspect, the filtration device may optionally further include a fixing frame located outside the housing and connected to the housing.

[0035] The above technical solution proposes to set a fixing frame on the outside of the box, which facilitates the installation of the filtration equipment into the dehumidifier.

[0036] In conjunction with the first aspect, optionally, the fixing frame is provided with a fixing mechanism, the fixing mechanism including a connector and a sealing gasket, the sealing gasket being disposed between the connector and the fixing frame.

[0037] The above technical solution proposes placing a sealing gasket between the connector and the fixing frame, which can prevent gaps at the connection and improve the waterproofness of the filtration equipment.

[0038] Secondly, this utility model provides a dehumidifier, including the filtration device described in any one of the first aspects, wherein the filtration device is disposed at the inlet of the dehumidifier.

[0039] The above technical solution can avoid the problem of filter clogging and effectively increase the air intake of the dehumidifier.

[0040] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0041] The filtration device of this invention enables the filter screen to rotate relative to the cleaning mechanism, which then cleans away the dust on the filter screen, avoiding the problem of filter screen clogging and effectively increasing the air intake of the dehumidifier.

[0042] This utility model provides a mechanism that enables the filter screen to rotate. In specific applications, the drive mechanism drives the toothed ring to rotate relative to the ring and cylinder. The rotation of the toothed ring drives the filter screen to rotate. As the filter screen rotates, the cleaning mechanism cleans the dust off the filter screen, avoiding the problem of filter screen clogging, thereby effectively increasing the air intake of the dehumidifier.

[0043] This utility model provides a specific structure for the shaft fixing component, which uses a first connecting rod to fix the first fixing column inside the cylinder, thereby achieving the fixation of the cleaning mechanism.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0056] The application principle of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0057] This embodiment provides a filtration device, such as... Figures 1-3 As shown, it includes: housing 1, filter screen 3, cleaning mechanism and drive mechanism;

[0058] The filter screen 3 is rotatably connected to the housing 1;

[0059] The cleaning mechanism comes into contact with the filter screen 3;

[0060] The drive mechanism is connected to the filter screen 3 and drives the filter screen 3 to rotate relative to the cleaning mechanism.

[0061] The above technical solution enables the filter screen 3 to rotate relative to the cleaning mechanism, allowing the cleaning mechanism to remove dust from the filter screen 3, thus avoiding clogging and effectively increasing the air intake of the dehumidifier. In practical implementation, the housing 1 has a hollow structure, which effectively reduces the overall weight of the filtration equipment and facilitates installation into the dehumidifier.

[0062] In one specific embodiment of this example, the box 1 is provided with a first notch and a second notch on opposite sides; the filter device also includes a circular ring 8, a cylindrical cylinder 10 and a toothed ring 9; in the specific implementation process, the cross-sections of the first notch and the second notch are both circular, and their central axes coincide.

[0063] The ring 8 is fixedly connected to the first notch;

[0064] Both ends of the cylinder 10 are open structures, one end of which is fixedly connected to the second notch, and the other end is located inside the box 1;

[0065] The toothed ring 9 is disposed between the ring 8 and the cylinder 10 and can rotate relative to the ring 8 and the cylinder 10;

[0066] The filter screen 3 is disposed on the toothed ring 9 and covers the entire toothed ring 9.

[0067] The above technical solution provides a mechanism that enables the filter screen 3 to rotate. In specific applications, the drive mechanism drives the toothed ring 9 to rotate relative to the ring 8 and the cylinder 10. The rotation of the toothed ring 9 will drive the filter screen 3 to rotate. As the filter screen 3 rotates, the cleaning mechanism cleans the dust on the filter screen 3, thereby effectively increasing the air intake of the dehumidifier and avoiding the problem of filter screen 3 clogging.

[0068] In one specific embodiment of this example, the cleaning mechanism includes a shaft 15, a shaft fixing member, a bristle fixing member 7, and bristles 2;

[0069] One end of the shaft 15 passes through the filter screen 3 and is connected to the bristle fixing member 7, and the other end is connected to the shaft fixing member. The shaft fixing member is also connected to the cylinder 10. The filter screen 3 can rotate relative to the shaft 15.

[0070] The bristles 2 are disposed on the bristle fixing member 7 near the filter screen 3 and in contact with the filter screen 3. In specific implementation, the bristle fixing member 7 is rod-shaped, with its axis parallel to the central axis of the filter screen 3, and its length equal to the diameter of the filter screen 3. The bristles 2 cover the entire bristle fixing member 7, and the extension direction of the bristles 2 is perpendicular to the plane where the filter screen 3 is located, so that the bristles 2 can clean the entire filter screen 3. The bristle fixing member 7 is connected to the shaft 15 by at least two screws, which facilitates the disassembly of the bristle fixing member 7.

[0071] The above technical solution provides a specific structure for a cleaning mechanism. The shaft 15 is fixedly connected to the cylinder 10 through the shaft fixing member and is also connected to the bristle fixing member 7. Since the cleaning mechanism is in a stationary state, when the filter screen 3 is driven to rotate by the driving mechanism, the filter screen 3 and the cleaning mechanism will generate relative motion, thereby realizing the cleaning of dust on the filter screen 3 by the cleaning mechanism.

[0072] In one specific embodiment of this invention, the shaft fixing member includes a first fixing post 12 and a first connecting rod 11;

[0073] The first fixing post 12 is located inside the cylinder 10 and is connected to the shaft 15;

[0074] One end of the first connecting rod 11 is connected to the first fixed column 12, and the other end is connected to the cylinder 10. In specific implementation, there can be one or more first connecting rods 11. When there are multiple first connecting rods 11, the first connecting rods 11 are arranged at equal intervals, which can improve the stability of the overall structure.

[0075] The above technical solution provides a specific structure for the shaft fixing component, which uses the first connecting rod 11 to fix the first fixing column 12 inside the cylinder 10, thereby achieving the fixation of the cleaning mechanism.

[0076] In one specific embodiment of this example, the filtration device further includes a second fixed column 16 and a second connecting rod 17;

[0077] The second fixing post 16 is located inside the housing 1 and is close to or in contact with the filter screen 3;

[0078] The two ends of the second connecting rod 17 are respectively connected to the second fixed post 16 and the toothed ring 9; in specific implementation, the number of the second connecting rod 17 can be one or more. When the number of the second connecting rod 17 is multiple, each second connecting rod 17 is arranged at equal intervals, which can improve the stability of the overall structure.

[0079] The shaft 15 passes through the second fixing post 16 and the filter screen 3 in sequence and is connected to the bristle fixing member 7. The second fixing post 16 and the filter screen 3 can rotate relative to the shaft 15.

[0080] The above technical solution utilizes the cooperation of the second fixed column 16 and the second connecting rod 17 to support the shaft 15, thereby improving the structural stability of the filtration device in this utility model.

[0081] In one specific embodiment of this example, the toothed ring 9 is rotatably connected to the ring 8 and the cylinder 10 via a first bearing ring and a second bearing ring, respectively.

[0082] The above technical solution utilizes a first bearing ring and a second bearing ring to separate the toothed ring 9 from the circular ring 8 and the cylinder 10, and the toothed ring 9 can rotate relative to the circular ring 8 and the cylinder 10. The structure is simple and can ensure the rotation effect.

[0083] In one specific embodiment of this example, the driving mechanism includes a drive motor 13 and a gear 14;

[0084] The gear 14 is connected to the output end of the drive motor 13 and also meshes with the gear ring 9, facilitating the rotation of the filter screen 3. In a specific implementation, the drive motor 13 is located at the bottom inside the housing 1, and both the gear 14 and the drive motor 13 are located below the gear ring 9.

[0085] The above technical solution provides a specific structure for the drive mechanism, which includes a drive motor 13 and a gear 14. The structure is simple, and all parts can be directly purchased from the market, thereby effectively reducing production costs.

[0086] In one specific embodiment of this invention, the filtration device further includes a fixing frame 4, which is located outside the housing 1 and connected to the housing 1. In practice, the fixing frame 4 is located on the side of the housing 1 closest to the dehumidifier, facilitating the installation of the filtration device on the dehumidifier.

[0087] The above technical solution proposes to set a fixing frame 4 on the outside of the housing 1, which facilitates the installation of the filter equipment into the dehumidifier.

[0088] In one specific embodiment of this invention, the fixing frame 4 is provided with a fixing mechanism, which includes a connector and a sealing gasket 6, with the sealing gasket 6 disposed between the connector and the fixing frame 4. In a specific implementation, the connector is a bolt 5, and the four corners of the fixing frame 4 are respectively provided with threaded holes, with bolts 5 threadedly connected to the threaded holes, facilitating the fixing of the filtration equipment.

[0089] The above technical solution proposes to place the sealing gasket 6 between the connector and the fixing frame 4, which can avoid gaps at the connection and improve the waterproofness of the filtration equipment. Example 2

[0090] This embodiment provides a dehumidifier, including the filtration device described in any one of Embodiment 1, wherein the filtration device is located at the inlet of the dehumidifier.

[0091] When using it, first align the fixing frame 4 with the position reserved in advance on the dehumidifier, and rotate the bolt 5 through the threaded hole on the fixing frame 4 into the threaded hole opened in advance on the dehumidifier until the sealing gasket 6 contacts the air inlet of the dehumidifier and stop rotating.

[0092] When the dehumidifier is turned on, the drive motor 13 is activated. The output of the drive motor 13 drives the gear 14 to rotate. The gear 14 meshes with the gear ring 9 and rotates, thereby driving the gear ring 9 to rotate. The gear ring 9 rotates between the ring 8 and the cylinder 10 through the first bearing ring and the second bearing ring. Since the filter screen 3, the second connecting rod 17, and the second fixing post 16 are all fixed on the gear ring 9, and the shaft 15 and the second fixing post 16 are rotatably connected through the bearing ring, the gear ring 9 drives the filter screen 3, the second connecting rod 17, and the second fixing post 16 to rotate. Since the shaft 15 is fixed on the first fixing post 12, and the first fixing post 12 is fixed on the cylinder 10 through the first connecting rod 11, and the cylinder 10 is fixed at the second notch (i.e., the circular opening), the brush fixing part 7 and the brush 2 are also fixed. As the filter screen 3 rotates, the dust on the filter screen 3 is swept away by the brush 2, which effectively increases the air intake of the dehumidifier and avoids the problem of filter screen 3 clogging.

[0093] 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.
