Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a window, and more particularly to a window that automatically removes contaminants attached thereto. [Prior Art] [0002] As the demand for security increases, the security monitoring system has gradually been adopted as a basic security device for home or community. One of the most important devices in a security surveillance system is the surveillance camera. Since the surveillance camera often needs to be installed outdoors, it is usually provided with a waterproof and dustproof casing for the surveillance camera to be installed in order to protect the surveillance camera from moisture and dust, and a device will be installed on the casing. The transparent window allows the surveillance camera to monitor external images through a transparent window. [0003] However, the above transparent window is still inevitably contaminated with moisture or dust on its surface under long-term outdoor wind and rain. Over time, contaminants will gradually accumulate on the transparent window, causing the transparency of the transparent window to gradually decrease, and may even affect the photographic quality of the surveillance camera, so that the security protection effect is not as expected. Therefore, for the above reasons, it is indeed necessary to provide an automatic cleaning device for the transparent window, for example, a device similar to a vehicle wiper can be used to scrape the contaminants adhering to the transparent window. However, since the wiper is made of a soft material such as rubber that does not damage the window, such a soft material often deteriorates under long-term use and needs to be periodically replaced to maintain its usability. Generally, a general security monitoring system often uses a plurality of surveillance cameras. In addition, not only the maintenance cost is high, but also the operation of the monitoring system needs to be suspended during maintenance. 099112692 Form No. A0101 Page 3 / 21 pages 0992022441-0 201136675, also becomes the window of safety monitoring, therefore, it is necessary to improve SUMMARY OF THE INVENTION [0005] In view of the above, an object of the present invention is to provide a rotary self-cleaning window that can be driven by electromagnetic force to cause a contaminant attached to a window to be removed by centrifugal force. In order to achieve the above object, a rotary self-cleaning window of the present invention mainly comprises a base, an annular bearing, a rotating tube, a transparent window, a permanent magnet group, and an electromagnetic coil group. The base has a through hole. The annular bearing is embedded in the through hole. The rotating tube is tightly fitted in the annular bearing and is rotatable relative to the base by the annular bearing. The transparent window cover is open at one end of the rotating tube. The permanent magnet group is disposed outside the opening of the other end of the rotating tube. The electromagnetic coil assembly is disposed on the base for driving the permanent magnet group to drive the rotating tube and the transparent window to rotate relative to the base when receiving power supply. In addition, another rotary self-cleaning window of the present invention mainly comprises a base, a tube member, a transparent window, and an electromagnetic coil assembly. The base has a through hole. The tubular member has a smaller diameter than the through hole and is movably disposed in the through hole. The tubular member has a metal ring. The transparent window cover is open at one end of the tubular member. The electromagnetic coil assembly is disposed on the base and has a plurality of coils that can be independently driven by electric power, each of the coils for attracting the metal ring to drive the tubular member and the transparent window on the base when receiving power supply The movement of the seat through the hole. [Embodiment] [0008] The technical content, detailed description, and efficacy of the present invention are now matched with 099112692 Form No. A0101 Page 4 / Total 21 Page 0992022441-0 201136675 The following is a description: [0009] As shown in the second figure, the first preferred embodiment of the rotary self-cleaning window of the present invention comprises a base 10, an annular bearing 2, a rotating tube 30, and a transparent window 40. A permanent magnet group 50, an electromagnetic coil assembly 60, and a protective cover 70. [0010] The susceptor 10 has a substantially square plate shape, and the actual implementation is not limited thereto. The susceptor 10 has various shapes, and the susceptor 10 has a through hole 贯穿 extending through the upper and lower surfaces thereof. In practical applications, the pedestal 1 连接 is attached to the housing of the surveillance camera, 〇 [0011] or actually a part of the housing. The annular bearing 2 is embedded in the through hole 11. The annular bearing 2 has an inner diameter which is adapted to accommodate the rotary tube 30. The rotary tube 30 is tightly fitted within the annular bearing 20 and is rotatable relative to the base 10 by the annular bearing 2. The rotary tube 30 has opposite end openings 31, 32. The transparent view 61 40 is provided at one end opening 31 of the rotating tube 30. The material of the transparent window 40 is not limited to being made of various glass, quartz, or plastic materials. 〇 [0012] The permanent magnet group 50 is disposed outside the opening 32 of the other end of the rotating tube 30. The permanent magnet group 50 has a support ring 51 ′ disposed around the rotating tube 30 and has a plurality of permanent magnets 52 disposed on the support ring 51 . The electromagnetic coil assembly 60 is disposed on the base 1〇. The electromagnetic coil assembly 60 has an annular core 61 having an annular portion 611 'and a plurality of extending portions 612 extending inwardly from the annular portion 611. The electromagnetic coil assembly 60 has a plurality of windings respectively. The coil 6 2 099112692 on the extension portion 612 Form No. A0101 Page 5 / Total 21 Page 0992022441-0 201136675 [0013] The protective cover 70 is disposed on the base 10 and covers the periphery of the transparent window 40 for the purpose of reducing Water vapor or dust intrudes into the minute gap 80 between the base 10 and the transparent window 40. [0014] As shown in the third figure, the electromagnetic coil assembly 60 can generate an electromagnetic field to drive the permanent magnet group 50 to drive the rotating tube 30 and the transparent window 40 at a high speed relative to the base 10 when receiving external power supply. Turn. Thereby, as shown in the fourth figure, when the rotary self-cleaning window 100 of the present invention is actually applied to the outer casing 300 of the surveillance camera, when the transparent window 40 is rotated at a high speed, the transparent window 40 can be attached to the transparent window. The contaminant t such as moisture or dust on the 40 is removed from the transparent window 40 by the centrifugal force, so as to restore the original transparency of the transparent window 40, thereby effectively preventing the accumulation of contaminants on the transparent window 40, and The gradual decrease in the light transmittance of the transparent window 40 occurs. It should be noted that the rotary self-cleaning window 100 of the present embodiment is applied to the outer casing 300 of the surveillance camera. However, in practice, when it is not limited thereto, it can be applied to various indoor or outdoor windows. [0015] As shown in the fifth and sixth figures, the second preferred embodiment of the rotary self-cleaning window 200 of the present invention mainly includes a base 10, a tube member 90, a transparent window 40, and an electromagnetic The coil assembly 60, and a protective cover 70. Since the susceptor 10, the transparent window 40, the electromagnetic coil group 60, and the protective cover 70 are the same as those of the first preferred embodiment, they will not be repeatedly described in this embodiment. [0016] The rotary self-cleaning window 200 of the embodiment is different in that a tube member 90 having a smaller diameter than the through hole 11 of the base 10 is provided, so that the tube member 90 is movably disposed in the through hole. 11 inside. The pipe member 90 has a body 91 and 099112692. Form No. 1010101 Page 6 of 21 0992022441-0 201136675 ❹ [0017] A set of metal rings 92 made of a magnetic metal material provided on the body 91. The transparent window 40 is disposed on the end opening 93 of the tube member 9. As shown in the seventh embodiment, unlike the first preferred embodiment, each of the coils 62 of the electromagnetic coil assembly 60 of the present embodiment is The electric drive can be independently received to generate an electromagnetic field when the power supply is received, so as to drive the metal ring 92 to drive the body 91 and the transparent window 4 to move in the through hole 11 of the base 1 . In addition, the rotary self-cleaning window 2 of the embodiment further includes a lining ring 63 disposed in the extending portions 612 of the electromagnetic coil assembly 60 to reduce friction between the metal ring 92 and the extending portions 612. The metal ring 92 and the body 91 can be moved more smoothly. Ο [0018] By adjusting the driving manner of the coil 61, such as the driving time and the driving sequence, the movement manner of the transparent window 40 in the through hole u of the pedestal 1 呈现 can be moved, scrolled, and One of the rotations. Thereby, as shown in the seventh and eighth figures, when the transparent window 4 is moved at a high speed, the contaminant such as moisture or dust adhering to the transparent window 40 can be subjected to centrifugal force. The transparent window 40 is removed to restore the original transparency of the transparent window 40, which can effectively prevent the accumulation of contaminants on the transparent window 40, and the light transmittance of the transparent window 4 is reduced. In addition, as shown in FIG. 9 , the rotating self-cleaning window 1 of the present invention may further include a pollutant detecting module 400 for detecting whether moisture or dust is present on the transparent window 4 . Contaminants. The contaminant detection module 4 includes a light-emitting element 42A extending toward an inner surface of the transparent window 40 and a light-receiving element 410. The light-emitting element 420 is configured to emit light toward the inner surface of the transparent window 4'. The light-receiving element 410 is configured to receive light, as it is 099112692, Form No. A0101, Page 7 / 21 pages 0992022441-0 201136675 The contaminant will affect the transparency of the transparent window 40, and the intensity of the light received by the light-receiving element 41 will change correspondingly. The pollutant detection module 4 determines the intensity of the received precursor line, and determines the amount of contaminants on the transparent window 40. In addition, the rotary self-cleaning window 100 of the present invention may further include a spraying device 5 喷洒 for spraying a gas or a liquid on the outer surface of the transparent window 4 through a nozzle 51 to remove the transparent window 40. Contaminants. The spraying device 500 can be used in combination with the pollutant detecting module 4, and when the pollutant detecting module 400 detects the presence of contaminants on the transparent window 4, the spraying device 500 can be used. A gas or liquid is sprayed to remove contaminants from the transparent window 40. As shown in the tenth figure, it is an embodiment of another type of pollutant detecting module 6〇G. The black contaminant detection module 600 includes a light-emitting element 62 〇 ' extending toward the inner surface of the transparent window 4 以及 and a light-receiving element 61 延 extending toward the outer surface of the transparent window 4Q. The light-emitting element emits light toward the inner surface of the transparent window ♦, and the light-receiving element is used to receive light. Since the contaminant on the transparent window 40 reflects the transparency of the transparent window 4 (), the light-receiving element 6 The light intensity of _ (4) will change accordingly. The amount of contaminants on the transparent window 40 can be judged by the intensity of the light from the contaminant. It should be noted that the pollutant side module and the spraying and placing of the ninth and tenth drawings are attached to the self-cleaning window of the preferred embodiment as shown in the first and second embodiments. In the actual implementation, it can also be applied to the rotary self-cleaning (four) 如 according to the second preferred embodiment of the fifth and sixth figures.
