Description

Technical Field

[0001] The present invention relates to the technical field of ship air purification, and in particular to an air purification filter impurity cleaning device and a ship air purifier. Background Art

[0002] A marine air purifier is a device that filters and purifies indoor air. Its built-in filter removes pollutants such as dust particles, bacteria, viruses, and harmful gases from the air, thereby improving the air quality in the corresponding cabin and reducing harm to the human body. The filter can be an air purification filter. After an air purifier has been used for a period of time, a large amount of dust will accumulate on the filter, necessitating regular cleaning of the filter. Typically, the filter is periodically removed from the air purifier housing, cleaned, and then reinstalled into the housing. Current cleaning methods are time-consuming and labor-intensive, and can lead to untimely or excessive cleaning. Specifically, during the period of use, the filter may still function, failing to meet cleaning standards. Removing the filter for cleaning may result in over-cleaning. Alternatively, due to particularly poor environmental conditions, the filter may no longer function, but the cleaning time has not yet arrived, resulting in untimely cleaning of the filter.

[0041] In the description of the present embodiment, reference to the terms "one embodiment," "some embodiments," "illustrative embodiments," "example," "specific example," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the exemplary expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any appropriate manner in any one or more embodiments or examples.

[0042] Figure 1FIG. 1 is a schematic structural diagram of an air purification filter impurity cleaning device according to an embodiment of the present invention. Figure 1 As shown, and reference Figures 2 to 11 , an embodiment of the present invention provides an air purification filter impurity cleaning device. The air purification filter impurity cleaning device includes a collection box 10, a cleaning device 20 and a shielding device. The collection box 10 has a collection space with an opening facing upward. The cleaning device 20 is installed on the upper side of the front end of the collection box 10 so as to be movable up and down. The cleaning device 20 can clean vertically arranged planes, such as the vertical surface of the shell, the air inlet side surface and the air outlet side surface of the filter device, etc. In the initial position, the cleaning device 20 is located in the collection space. This arrangement ensures that the cleaning device 20 does not occupy additional space when not in use, and impurities such as dust carried on the cleaning device 20 will not be outside the collection box 10, causing impurities to fly around. The shielding device includes a first winding shaft 31, a second winding shaft 32 and a first shielding cloth 33. The first winding shaft 31 is rotatably installed on the cleaning device 20 so as to move up and down with the cleaning device 20. The second winding shaft 32 is rotatably mounted on the rear end of the collecting box 10 ; both ends of the first shielding cloth 33 are fixedly connected to the first winding shaft 31 and the second winding shaft 32 , and part of the first shielding cloth 33 is wound on the first winding shaft 31 or the second winding shaft 32 .

[0043] When the air purification filter impurity cleaning device of the embodiment of the present invention is working, the collection box 10 can be placed near the device to be cleaned, preferably on the lower side of the device to be cleaned, or in contact with the lower surface of the device to be cleaned. For example, a guide plate 11 is provided at the front end of the collection box 10, and the guide plate 11 extends obliquely forward and upward from the front end of the collection box 10, and the guide plate contacts the lower end of the surface to be cleaned of the device to be cleaned. The driving device is started to move the cleaning device 20 up and down for cleaning. At this time, the first winding shaft 31 moves up and down with the cleaning device 20, and the first shielding cloth 33 is expanded and retracted when the distance between the first winding shaft 31 and the second winding shaft 32 changes, so that an impurity floating space is formed between the lower side of the cleaning device 20, the device to be cleaned and the collection box 10, so that the impurities will not move to other ends, thereby preventing the impurities from flying around. In particular, when cleaning downward, the impurity floating space gradually becomes smaller, which will prompt the impurities to enter the collection space of the collection box 10. When the cleaning is completed, the cleaning device 20 enters the collection box 10. At this time, the first winding shaft 31 is at the front end of the collection box 10, and the second winding shaft 32 is at the rear end of the collection box 10. The first shielding cloth 33 can close the opening of the collection box 10. Therefore, there is no need to set a special opening and closing device for opening and closing the opening of the collection box 10, which can ensure that impurities are collected.

[0044] Moreover, in the embodiment of the present invention, when the upper side of the collecting box 10 has other devices, for example, Figure 8As shown, the first filter device and the second filter device are arranged in sequence from front to back. When the rear surface of the first filter device is cleaned, the second filter device will be on the upper side of the collection space, and one end of the first shielding cloth 33 will go around the lower end of the second filter device when it is raised and lowered along with the first winding shaft 31. In other words, when the first filter device is cleaned, the cleaning space is relatively small, and it will not affect the cleaning of the air purification filter impurity cleaning device, which significantly improves the applicability of the air purification filter impurity cleaning device, and is particularly suitable for the case where there are multiple filter devices in the ship air purifier. Further, as Figure 7 As shown, the air purification filter impurity cleaning device of the embodiment of the present invention can also clean the vertical surface of the shell, especially the inner surface of the area where the air outlet is located on the shell. As time goes by, impurities will also appear on the inner surface of the area where the air outlet is located. The air purification filter impurity cleaning device of the embodiment of the present invention can be moved to this position or set at this position for cleaning.

[0045] Therefore, the air purifier filter impurity cleaning device of the embodiment of the present invention, because it includes a cleaning device 20, can be installed within the housing of a marine air purifier to clean corresponding locations within the housing of the marine air purifier, particularly the air inlet surface of the filter device. Specifically, the device can operate according to the amount of impurities on the surface of the filter device. That is, the air purifier filter impurity cleaning device can clean the filter device in a timely manner according to the needs of the filter device, eliminating the need for cleaning based on time, making cleaning more convenient and saving manpower and material resources.

[0046] Furthermore, because there is a shielding cloth that moves up and down with the cleaning device 20, the shielding cloth can promote the cleaned impurities to enter the collection box 10 as the cleaning device 20 moves downward, preventing the impurities from flying around. After cleaning is completed, the collection box 10 can also be closed to prevent the collected impurities from entering the shell again, thereby facilitating the transfer and processing of impurities.

[0047] Furthermore, the cleaning device 20 can not only clean the air inlet side surface of the filter device, but can also be configured to clean the air outlet side surface of the filter device, and can also clean the surface on the inner surface of the shell that needs to be cleaned, such as cleaning the inner surface of the part of the shell where the air outlet is located, which can ensure the cleanliness of multiple parts in the shell, so that the ship air purifier itself is clean, further ensuring the cleanliness of the purified air.

[0048] In some embodiments of the present invention, the air purification filter impurity cleaning device further includes a bracket and a lifting device. The collection box 10 is connected to the bracket; and the bracket includes two vertically arranged mounting brackets 41, and the two mounting brackets 41 are arranged on both sides of the front end of the collection box 10. The lifting device is installed on the two mounting brackets 41, and is configured to drive the cleaning device 20 to move downward along the first path for cleaning, and move upward along the second path to the upper end of the first path; the first path is arranged in front of the second path. Figure 4 , the cleaning device 20 is on the first path.

[0049] In the embodiment of the present invention, when the lifting device drives the cleaning device 20 upward, there is a certain gap between it and the device to be cleaned. This prevents the device to be cleaned from being cleaned. Because cleaning is done upward, the first shielding cloth 33 cannot effectively cover it, causing impurities to fly around. Therefore, when the lifting device drives the cleaning device 20 downward, it contacts the device to be cleaned to clean it, ensuring overall cleanliness after cleaning and preventing other problems caused by cleaning.

[0050] For example, in some preferred embodiments of the present invention, the lifting device includes a motor and two drive belt assemblies, each mounted on a mounting frame 41. Each drive belt assembly includes a vertically arranged drive belt 43, with pulleys 42 mounted on the mounting frame 41 at the upper and lower ends of the drive belt 43. The motor drives the pulleys 42 to rotate. The ends of the cleaning device 20 are mounted on the two drive belts 43. By utilizing the spacing between the two vertical sections of the drive belt 43, continuous operation is achieved without changing the direction of motor rotation, simplifying the control of the motor that drives the drive belt assembly.

[0051] In some embodiments of the present invention, Figure 2 As shown, the lower end of each mounting bracket 41 is rotatably arranged to rotate to a horizontal state and be located outside the collection box 10. This arrangement facilitates the storage of the air purification filter impurity cleaning device, especially when the air purification filter impurity cleaning device needs to be moved, the structure of the air purification filter impurity cleaning device can be made compact and easy to move.

[0052] In some alternative embodiments of the present invention, each mounting bracket 41 is a telescopic bracket, which can be extended to the shortest state when cleaning is not performed, and can be extended to the longest state when cleaning is required. Figure 3As shown, the lower end of each mounting bracket 41 is rotatably arranged, and each mounting bracket 41 is a telescopic bracket to adapt to a smaller usage space, that is, when the cleaning space where the device to be cleaned is located is particularly small, the air purification filter impurity cleaning device of the embodiment of the present invention can also enable the telescopic bracket to expand and contract to prevent the device to be cleaned from being unable to be cleaned due to insufficient space.

[0053] In some embodiments of the present invention, in order to further improve the sealing and dustproof performance, a second shielding cloth that can be folded and unfolded is provided between each mounting frame 41 and the collection box 10, and the two second shielding cloths are located on both sides of the first shielding cloth 33.

[0054] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the bracket is also provided with a roller 45 located on the lower side of the collection box 10, and a drive device that causes the roller 45 to rotate and the collection box 10 to turn. In other words, the drive device can drive the roller 45 to move the air purification filter impurity cleaning device back and forth to the cleaning station. Moreover, when the rear surface of the filter device needs to be cleaned, the front side of the cleaning device 20 faces the rear surface of the filter device. When the rear surface of the filter device needs to be cleaned, the drive device causes the collection box 10 to turn so that the front side of the cleaning device 20 faces the front surface of the filter device, thereby achieving cleaning of both sides of the filter device.

[0055] Specifically, the bracket includes a chassis 46, on which rollers 45 are mounted. A drive mechanism is mounted on chassis 46 and includes a first drive mechanism and a second drive mechanism. The first drive mechanism drives rollers 45 forward and backward. The collection box 10 is rotatably mounted on chassis 46, while the second drive mechanism drives the collection box 10 through a full 360° rotation. The cleaning mechanism 20 and the shielding mechanism rotate synchronously with the collection box 10.

[0056] In some embodiments of the present invention, Figure 5 As shown, the air purification filter impurity cleaning device also includes an upper scraper 50. The upper scraper 50 is disposed on the cleaning device 20 and is located above the cleaning device 20. The front end of the upper scraper 50 is configured to contact the surface to be cleaned. The first winding shaft 31 is disposed below the rear end of the upper scraper 50, and the first shielding cloth 33 contacts and abuts against the upper scraper 50. In this embodiment, the upper scraper 50 can have two functions. First, it cooperates with the first shielding cloth 33 to seal the upper side of the cleaning device 20. Second, the scraper can scrape impurities that are difficult for the cleaning device 20 to remove, thereby removing as much impurities as possible.

[0057] In some preferred embodiments of the present invention, the rear end of the upper scraper 50 is provided with a perforation 51, through which the first screen 33 passes. The perforation 51 ensures a close fit between the upper scraper 50 and the first screen 33, ensuring a secure seal. The perforation 51 also limits the left-right movement of the first screen 33.

[0058] Moreover, the air purification filter impurity cleaning device further comprises an elastic device 52, which is disposed between the upper scraper 50 and the cleaning device 20 and is configured to cause the upper scraper 50 to move forward relative to the cleaning device 20. By providing the elastic device 52, it is ensured that the upper scraper 50 acts on the corresponding surface of the device to be cleaned.

[0059] In some embodiments of the present invention, the air purification filter impurity cleaning device further includes two torsion springs, which are respectively disposed on the first winding shaft 31 and the second winding shaft 32 to cause the first winding shaft 31 and the second winding shaft 32 to rotate in opposite directions, thereby keeping the first shielding cloth 33 in a taut state at all times.

[0060] The embodiment of the present invention also provides an air purifier for ships, such as Figures 6 to 11 As shown, the marine air purifier includes a housing 60, a fan 71 and a filter device 72 disposed within the housing 60, and the air purification filter impurity cleaning device of any of the above-described embodiments. The fan 71 is disposed in front of the filter device 72 and is configured to force airflow from the rear side of the filter device 72 to the front side of the filter device 72. The cleaning device 20 is disposed in the rear side of the filter device 72 and is configured to clean the rear surface of the filter device 72.

[0061] When the marine air purifier according to the embodiment of the present invention is in operation, Figure 6 As shown, the fan 71 is started, causing air to enter the housing 60 from the air inlet 61 on the housing 60. After being filtered and purified by the filter device 72, the air flows out of the housing 60 from the air outlet 62 of the housing 60. At this time, the first shielding cloth 33 is in a shielding position that blocks the opening of the collection box 10, so that the collection box 10 is closed. The airflow generated by the fan 71 will not cause the dirt in the collection box 10 to flow out of the collection box 10. When it is necessary to clean the air inlet side surface of the filter device 72, the cleaning device 20 moves upward and downward to clean it. The front end of the first shielding cloth 33 rises and falls with the cleaning device 20, allowing the raised impurities to enter the collection box 10, effectively collecting the impurities.

[0062] In some embodiments of the present invention, Figure 8As shown, there are multiple filter devices 72, which are arranged in sequence from front to back; the air purification filter impurity cleaning device is movably arranged on the lower side of the multiple filter devices 72 along the front-to-back direction. In the embodiment of the present invention, since the air purification filter impurity cleaning device is movably arranged along the front-to-back direction, when a filter device 72 needs to be cleaned, the air purification filter impurity cleaning device can be moved to the corresponding position, and then the rear surface of the corresponding filter device 72 can be cleaned. In particular, Figure 7 As shown, the air purification filter impurity cleaning device can also be moved to the corresponding position of the end where the air outlet 62 is located on the shell 60 to clean the inner surface of the end where the air outlet 62 is located on the shell 60.

[0063] In some embodiments of the present invention, Figures 9 to 11 As shown, the housing 60 includes a main housing 64 and a channel housing 65. The main housing 64 has a downward opening, and the channel housing 65 is movably arranged at the opening of the main housing 64. The front end of the main housing 64 is provided with the above-mentioned air outlet 62, and the rear end is provided with the above-mentioned air inlet 61. The fan 71 and the filter device 72 are arranged in the main housing 64. When the channel housing 65 moves upward to close the downward opening of the main housing 64, it also closes the filter device 72 to prevent the air flow from the lower side of the filter device 72 from flowing forward. After the channel housing 65 moves downward, it will define an inlet and outlet channel 67 extending forward and backward between it and the main housing 64. The air purification filter impurity cleaning device can be arranged on the rear side of the channel housing 65. After the inlet and outlet channel 67 is formed, the air purification filter impurity cleaning device can move back and forth in the inlet and outlet channel 67 to move to the corresponding cleaning station.

[0064] Furthermore, the housing 60 further includes a receiving housing 66 disposed on the lower side of the rear end of the main housing 64. The receiving housing 66 is located on the rear side of the duct housing 65. The air purification filter impurity cleaning device is detachably located within the receiving housing 66. When located within the receiving housing 66, the air purification filter impurity cleaning device can clean the rear surface of the rearmost filter device 72.

[0065] In some embodiments of the present invention, after the inlet and outlet channel 67 is formed, the air purification filter impurity cleaning device can also rotate the collection box 10 within the inlet and outlet channel 67 to clean both the front and rear surfaces of the filter device 72.

[0066] In some embodiments of the present invention, the marine air purifier includes a pressure differential detection device capable of detecting the pressure differential across each filter device 72. If the pressure differential across the filter device 72 exceeds a preset value, it is determined that the air inlet surface of the filter device 72 requires cleaning. The air inlet surface of the filter device 72 can be cleaned according to a preset cleaning duration.

[0067] At this point, those skilled in the art will recognize that, although a number of exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
