The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

Referring to fig. 1-3, a plasma liquid crystal display, including display housing 1, display housing 1 screen body both sides all are provided with spout 2, and the inside sliding connection of spout 2 has sliding block 3 to be provided with cleaning member 4 between two sliding blocks 3, cleaning member 4 can offset the setting with the screen body on display housing 1, in order to realize that sliding block 3 drives cleaning member 4 rebound's in-process, can realize cleaning member 4 and clean the screen body on display housing 1.

And further be provided with slip chamber 5 in display housing 1 inside, the inside magnetic plate 6 that is provided with of slip chamber 5, opposite sex attracts between magnetic plate 6 and the sliding block 3 to the realization adsorbs sliding block 3 through magnetic plate 6, with the realization that sliding block 3 can be stable stop inside spout 2, and can realize driving the removal of sliding block 3 through the removal of magnetic plate 6.

Wherein the removal of magnetic plate 6 can be realized through actuating mechanism 7, and actuating mechanism 7 includes driving motor 71 and threaded rod 72, and the vertical rotation of threaded rod 72 is connected inside sliding chamber 5, and threaded rod 72 runs through magnetic plate 6 and with magnetic plate 6 threaded connection, driving motor 71 fixed connection in display housing 1 bottom, and output and threaded rod 72 fixed connection. In order to realize that driving motor 71 drives threaded rod 72 pivoted in-process, threaded rod 72 will drive magnetic plate 6 rebound, and then realizes driving sliding block 3 through magnetic plate 6 and reciprocates.

The cleaning elements 4 can further be configured such that: cleaning member 4 comprises two cleaning plates 41, and nonparallel arrangement between two cleaning plates 41, also be for the dog-ear to constitute between two cleaning plates 41, and rotate on sliding block 3 and be connected with axis of rotation 8, axis of rotation 8 and cleaning member 4 fixed connection, be provided with between sliding block 3 and the display casing 1 with axis of rotation 8 matched with steering mechanism 9.

The steering mechanism 9 includes a steering wheel 91, a rotating groove 92 and a friction groove 93, the rotating groove 92 is provided on the sliding block 3, the rotating shaft 8 extends into the rotating groove 92 and is fixedly connected with the steering wheel 91, the friction groove 93 is provided on the display housing 1, and the side portion of the steering wheel 91 is abutted against the friction groove 93.

When the sliding block 3 moves downwards, the cleaning piece 4 deflects through the action of friction force between the friction groove 93 and the steering wheel 91, so that the cleaning plate 41 on the lower side of the cleaning piece 4 is abutted against the screen body to clean the screen body; when the sliding block 3 moves upwards, the steering wheel 91 can drive the cleaning element 4 to rotate by the action of the friction force between the friction groove 93 and the steering wheel 91, so that the cleaning plate 41 on the upper side of the cleaning element 4 is abutted to the screen body. And in the process of cleaning, when the sliding block 3 and the cleaning piece 4 move downwards, the cleaning plate 41 on the lower side of the cleaning piece 4 cleans the screen body, and when the sliding block 3 and the cleaning piece 4 move upwards, the cleaning plate 41 on the upper side of the cleaning piece 4 cleans the screen body. So as to prevent dust on the upper cleaning plate 41 from rubbing against the screen body and adhering to the screen body again during the downward movement; in the upward movement, the dust on the lower cleaning plate 41 is again attached to the screen body by friction with the screen body.

In the above-described configuration, a rubber layer may be provided on the outer ring side of the steering wheel 91, and the side wall of the friction groove 93 that abuts against the steering wheel 91 may be made of a frosted material, so that a certain frictional force may be provided between the steering wheel 91 and the friction groove 93.

Now, the operation principle of the present invention is described as follows:

when the screen body needs to be cleaned, the rotation of the threaded rod 72 can be realized by controlling the driving motor 71, so that the threaded rod 72 can drive the magnetic plate 6 to move up and down, the sliding block 3 can be controlled to move up and down under the action of magnetic force in the process of moving up and down the magnetic plate 6, and the sliding block 3 can drive the cleaning piece 4 to move up and down to clean the screen body; and because the sliding block 3 is through the magnetic force effect between 6 with the magnetic force in order to realize stable being located inside spout 2, so can the personnel convenient take off sliding block 3 from spout 2 to realize convenient cleaning 4.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
