1. Technical Field
The disclosure generally relates to lens cleaners and, particularly, to a lens cleaner with an air blowing member for removing dust on a lens.
2. Description of Related Art
Currently, a typical way for cleaning a lens is to blow off dust attracted on the lens by using an air gun. However, it is very difficult for the air gun to clean the lenses, as the dust may be attracted to the lenses by an electrostatic force.
What is needed, therefore, is a lens cleaner which can overcome the limitations described.
Many aspects of the disclosure can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present lens cleaner. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
Embodiment of the lens cleaner will now be described in detail below and with reference to the drawings.
Referring to
The fixture 10 is in the form of a chamber with a receiving space 10A. The loading plate 13, the guide member 14, and the cleaning members 15 are received in the fixture 10. The air blowing member 17 and the air evacuating member 16 are arranged outside the fixture 10. In this embodiment, the fixture 10 is substantially cuboid-shaped, and includes a top board 101, a bottom board 103, two first side boards 105 in parallel, and two second side boards 107 in parallel. The top board 101 and the bottom board 103 are substantially parallel with one another. The first side boards 105 and the second side boards 107 each are located between, and adjoins the top board 101 and the bottom board 103. Each of the second side boards 107 is located between and adjoins the two first side boards 105.

In this embodiment, the through hole 180 is substantially cylindrical. It is noted, when the tray 18 is secured in the loading plate 13, two opposite edge portions of the tray 18 is fittingly received in the two second slots 133, and a central portion of the tray 18 is exposed at the first slot 132.

The cleaning members 15 each includes a main body 150, an air blowing block 152, and an air evacuating block 154. In this embodiment, the two main bodies 150 each are substantially cuboid-shaped, and has a groove 1500 defined in a bottom thereof. The two grooves 1500 receive the two respective rails 140. Thereby the two cleaning members 15 are slidably attached on the two respective guide members 14.
The two main bodies 150 each includes a first upper surface 150A and a first lateral surface 150B adjoining the first upper surface 150A. The two first lateral surfaces 150B are substantially parallel to the loading surface 18A of the tray 18. In this embodiment, each main body 150 has a first receiving recess 150C and a second receiving recess 150D defined in the lateral surface 150B. Each of the first receiving recess 150C and the second receiving recess 150D is exposed at the first upper surface 150A. The air blowing block 152 is substantially cuboid-shaped, and is partially received in the first receiving recesses 15C. The air evacuating block 154 is substantially cuboid-shaped, and is partially received in the second receiving recess 150D.
The air blowing block 152 and the air evacuating block 154 each include a second upper surface 156 and a second lateral surface 158 adjoining the second upper surface 156. Each of the two second lateral surfaces 158 is inclined relative to the first lateral surface 150B of the main body 150. A lengthwise direction of the second lateral surface 158 of the air blowing block 152 intersects with a lengthwise direction of the second lateral surface 158 of the air evacuating block 154. In this embodiment, the two second lateral surfaces 158 are substantially perpendicular to each other in the lengthwise directions thereof. The air blowing block 152 has a first air inlet 152C defined in the second upper surface 156 thereof, and has a number of first air outlets 152D defined in the second lateral surface 158 thereof. The first air inlet 152C communicates with the first air outlets 152D. The air evacuating block 154 has a number of second air inlets 154C defined in the second lateral surface 158 thereof, and has a second air outlet 154D defined in the second upper surface 156 thereof. The second air inlets 154C communicate with the second air outlet 154D. The first air outlets 152D and the second air inlets 154C open toward the loading plate 13. In this embodiment, the first air outlets 152D of any of the cleaning members 15 face the second air inlets 154C of the other cleaning member 15.
The air blowing member 17 and the air evacuating member 16 are arranged on the first side board 105 (see
In operation, the two cleaning members 15 can be moved along two corresponding guide members 14 to locate at two opposite sides of the tray 18. When the first air outlets 152D and the second air inlets 154C open toward the loading surfaces 18A of the tray 18, the air blowing member 17 introduces airflow to the first air inlets 152C of the air blowing blocks 152 through the second pipes 170. The airflow is discharged from the first air outlets 152D to blow off dust on the surfaces of the lenses. Thus, the lenses are cleaned. In this embodiment, the first air outlets 152D blow air toward the loading plate 13 at an inclined angle. The air evacuating member 16 is configured for evacuating the air with the dust into the second air inlets 154C, and further out of the fixture 10 through the first pipes 170.
In alternative embodiments, the cleaning members 15 may be moved along the two guide members 14 to located between the trays 18 in sequence, thus cleaning the lenses efficiently.
The lens cleaner 100 may further include a dust gathering enclosure 19 and a vessel 20. In this embodiment, the enclosure 19 has a frusto-polygonal shape, and tapers away from the loading plate 13. That is, the enclosure 19 tapers toward the bottom board 103 of the fixture 10 in a vertical direction. The enclosure 19 includes a first opening 190 and a second opening 192 at two opposite sides thereof. The first opening 190 opens toward the loading plate 13, or the top board 101. A configuration of the first opening 190 is shaped to confirm to that of the fixture 10 in the receiving space 10A. The vessel 20 is connected to the dust gathering enclosure 19 at the second opening 192 thereof. The second opening 192 opens toward an inner surface (not labeled) of the vessel 20. In operation, dust that is not vented into the second air inlets 154C can fall off due to gravity and evacuating, thus the enclosure 19 thus can be used to gather the dust into the vessel 20.
In this embodiment, a third pipe 201 can be provided to connect an inner space of the vessel 20 to the air evacuating member 16. Thus, the dust gathered in the vessel 20 can be vented out of the fixture 10 by the air evacuating member 16. The lens cleaner 100 may include a dust gathering net 30 for gathering the dust thereon before the dust is vented into the vessel 20. The dust gathering net 30 can be arranged in the enclosure 19 between the first opening 190 and the second opening 192. In use, the dust gathering net 30 can be easily detached from the enclosure 19 to be cleaned.
In alternative embodiments, the lens cleaner 100 may include only one guide member 14 and only one cleaning member 15. In use, the cleaning member 15 can be moved along a side of the loading plate 13 to clean the lenses. It is noted, the lens cleaner 100 including only one guide member 14 and only one cleaning member 15 should also be considered within the scope of the disclosure.
It is understood that the above-described embodiment is intended to illustrate rather than limit the disclosure. Variations may be made to the embodiment without departing from the spirit of the disclosure. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the scope of the disclosure.
