Description

Technical Field

[0001] The utility model relates to the technical field of dust removal of touch screens, in particular to a dust removal device for a touch screen with an adsorption structure. Background Art

[0002] A touch screen, also known as a "touch screen" or "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts. When a graphic button on the screen is touched, the tactile feedback system on the screen can drive various connection devices according to a pre-programmed program. It can be used to replace mechanical button panels and create vivid audio and video effects through the LCD display.

[0003] The utility model patent with the patent announcement number CN 217911669 U discloses a dustproof device for a touch screen, including a touch screen body, a base and a bottom plate, wherein the base is fixedly connected to the bottom of the touch screen body, the bottom plate is fixedly connected to the bottom of the base, the right and left sides of the touch screen body are fixedly connected with a transmission box, and the rear side of the top of the touch screen body is fixedly connected with a limit box. The patent sets a time relay so that the time relay starts the transmission mechanism at a fixed time, so that the transmission mechanism drives the cleaning plate to remove dust from the surface of the touch screen body, thereby achieving the effect of timed dustproof, solving the problem that the surface of the touch screen does not have the function of automatic timed dustproof, dust will fall on the surface of the touch screen, and the dust will accumulate more and more over time, causing the user's hands to be covered with dust when using the touch screen, thereby reducing the user's use experience and achieving the effect of timed dustproofing of the touch screen.

[0004] However, the current touch screen dustproof device has the following problems: the surface of the touch screen will be constantly rubbed during the cleaning process by wiping with a cleaning plate, which will continuously damage the surface of the touch screen with long-term use and reduce the service life of the touch screen; and after the cleaning plate surface is adhered to dust, the dust will re-attach to the surface of the touch screen, making it impossible to clean the surface of the touch screen; and the touch screen dustproof device is not equipped with a dust collection device, which will cause personnel to clean the touch screen dustproof device again, which is more troublesome. Therefore, we propose a touch screen dust removal device with an adsorption structure. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a touch screen dust removal device with an adsorption structure, which solves the problems raised in the above background technology.

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions: a touch screen dust removal device with an adsorption structure, comprising a base, a touch screen is fixedly installed on the middle part of the base by bolts, an electrostatic adsorption device is arranged on the left side of the upper surface of the base, the electrostatic adsorption device comprises a motor and a corrugated plate, the motor is fixedly installed at the lower left corner of the upper surface of the base, and the motor is controlled by a relay, a threaded rod is fixedly connected to the output end of the motor, a threaded block is threadedly connected to the outer surface of the threaded rod, an electrostatic plate is fixedly connected to the side of the threaded block, the electrostatic plate is hollow, and a cover is installed on the upper part of the electrostatic plate, a telescopic rod is fixedly installed on the front end of the inner wall of the electrostatic plate, a brush is fixedly installed on the outer surface of the telescopic section of the telescopic rod, the corrugated plate is fixedly installed on the rear side of the inner wall of the base, the end of the telescopic rod away from the motor penetrates the electrostatic plate, the front side of the corrugated plate is wavy, the outer surface of the corrugated plate is slidably connected to the end of the telescopic rod away from the motor, a sliding rod is arranged at the rear end of the upper surface of the base, and the sliding rod is fixedly installed on the bottom by the supports at both ends. The upper surface of the seat and the outer surface of the slide rod are sleeved with a slider, and the slider is fixedly connected to the rear side of the electrostatic plate. The motor is controlled by a time relay, turned on according to the set time, and switched to counterclockwise rotation after a certain period of clockwise rotation. After a period of counterclockwise rotation, it switches to clockwise rotation, and repeats continuously. When turned on, the motor drives the threaded rod to rotate, and the threaded rod drives the threaded block to reciprocate on the threaded rod, so that the threaded block drives the electrostatic plate to reciprocate. Since the rear end of the electrostatic plate is fixed by the slider and the slide rod, it always remains perpendicular to the threaded rod during the reciprocating motion of the electrostatic plate. During the reciprocating motion of the telescopic rod, the wavy surface of the corrugated plate pushes the telescopic end of the telescopic rod, so that the telescopic end of the telescopic rod will reciprocate back and forth, and the brush fixed on the outer surface of the telescopic rod reciprocates back and forth synchronously. The brush continuously rubs the inner wall of the electrostatic plate to generate static electricity on the electrostatic plate, so that the electrostatic plate can use static electricity to absorb dust on the surface of the touch screen during the reciprocating motion, thereby achieving the effect of automatically and regularly removing dust from the surface of the touch screen.

[0007] According to the above technical solution, a beating device is arranged above the base, and the beating device includes a reset spring, the lower end of the reset spring is fixedly mounted on the upper surface of the electrostatic plate, the upper end of the reset spring is fixedly connected to a bracket, a beater is fixedly mounted on the lower surface of the horizontal section of the bracket, the end of the beater away from the bracket is in contact with the outer wall of the electrostatic plate, the lower part of the vertical section of the bracket is slidably mounted on the outside of the slider, and the lower end of the vertical section of the bracket is fixedly connected to a metal block. The flapping device also includes a sawtooth conductor, which is fixedly installed at the upper right corner of the upper surface of the base, and a grounding wire is fixedly connected to the right side of the sawtooth conductor. The sawtooth conductor is located on the movement trajectory of the metal block, and a dust box is plugged into the right side of the base. A cover plate is clamped on the surface of the base. When the bracket follows the electrostatic plate to move to the right, the metal block arranged at the lower end of the bracket will contact the sawtooth conductor at the end of the movement trajectory. Since the sawtooth conductor is connected to the grounding wire, when the bracket contacts the sawtooth conductor, the electrostatic plate will eliminate static electricity. In the process of contact between the metal block and the sawtooth conductor, the bracket will continue to rise and then fall through the reset spring, causing the entire bracket to vibrate for a period of time. The flapper on the bracket vibrates and flaps the upper surface of the electrostatic plate, so that the dust adsorbed by the electrostatic plate falls into the dust box below.

[0008] The utility model provides a touch screen dust removal device with an adsorption structure, which has the following beneficial effects:

[0009] (1) The utility model uses the arrangement of a motor, a threaded rod, a threaded block, an electrostatic plate, a slider, and a slide bar to enable the electrostatic plate to perform a periodic reciprocating motion to the left and right, thereby achieving the function of automatically and periodically removing dust from the surface of the touch screen. The arrangement of a telescopic rod, a brush, and a corrugated plate allows the electrostatic plate to continuously rub the inside of the corrugated plate to generate static electricity during its movement, thereby removing dust through electrostatic adsorption, thereby avoiding the situation where wiping and cleaning may damage the surface of the touch screen and the dust removal effect may be incomplete.

[0010] (2) The utility model uses a bracket, a metal block, a reset spring, a beater, a serrated conductor, and a grounding wire to enable the electrostatic plate to eliminate static electricity by itself during operation and shake off dust attached to the electrostatic plate into a dust box, thereby achieving the effect of automatically cleaning the electrostatic plate and preventing dust on the electrostatic plate from falling back onto the touch screen. Personnel only need to clean the dust box regularly, further simplifying the operation of personnel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figure 1-7An embodiment of the utility model is: a touch screen dust removal device with an adsorption structure, comprising a base 1, a touch screen 2 is fixedly installed in the middle of the base 1 by bolts 11, an electrostatic adsorption device 3 is arranged on the left side of the upper surface of the base 1, the electrostatic adsorption device 3 comprises a motor 33 and a corrugated plate 38, the motor 33 is fixedly installed at the lower left corner of the upper surface of the base 1, and the motor 33 is controlled by a relay, a threaded rod 31 is fixedly connected to the output end of the motor 33, a threaded block 32 is threadedly connected to the outer surface of the threaded rod 31, an electrostatic plate 35 is fixedly connected to the side of the threaded block 32, the electrostatic plate 35 is hollow, and a cover is installed on the upper part of the electrostatic plate 35, a telescopic rod 34 is fixedly installed on the front end of the inner wall of the electrostatic plate 35, a brush 36 is fixedly installed on the outer surface of the telescopic section of the telescopic rod 34, and the corrugated plate The outer surface of the corrugated plate 38 is slidably connected to the end of the telescopic rod 34 away from the motor 33. A sliding rod 37 is provided at the rear end of the upper surface of the base 1. The sliding rod 37 is fixedly mounted on the upper surface of the base 1 by means of supports at both ends. A sliding block 39 is sleeved on the outer surface of the sliding block 37. The sliding block 39 is fixedly connected to the rear side of the electrostatic plate 35. Through the arrangement of the above structure, the electrostatic plate 35 can absorb dust on the surface of the touch screen 2 by electrostatically adsorbing dust on the surface of the touch screen 2 during the reciprocating motion left and right, thereby achieving the effect of automatically and regularly removing dust on the surface of the touch screen 2. By means of electrostatic adsorption, it is avoided that wiping and cleaning will damage the surface of the touch screen 2 and the dust removal effect is not thorough.

[0021] According to the above technical scheme, a flapping device 4 is arranged above the base 1, and the flapping device 4 includes a reset spring 44, and the lower end of the reset spring 44 is fixedly installed on the upper surface of the electrostatic plate 35, and the upper end of the reset spring 44 is fixedly connected with a bracket 43, and a flapper 45 is fixedly installed on the lower surface of the horizontal section of the bracket 43, and the end of the flapper 45 away from the bracket 43 is in contact with the outer wall of the electrostatic plate 35, and the bracket 43 is slidably installed on the outside of the slider 39 below the vertical section, and the lower end of the vertical section of the bracket 43 is fixedly connected with a metal block 46. The beating device 4 also includes a sawtooth conductor 42, which is fixedly installed on the upper right corner of the upper surface of the base 1. A grounding wire 41 is fixedly connected to the right side of the sawtooth conductor 42. The sawtooth conductor 42 is located on the movement trajectory of the metal block 46. A dust box 5 is plugged into the right side of the base 1, and a cover plate 6 is clamped on the surface of the base 1. Through the setting of the above structure, the beater 45 on the bracket 43 vibrates and beats the upper surface of the electrostatic plate 35, so that the dust adsorbed by the electrostatic plate 35 falls into the dust box 5 below, thereby achieving the effect of automatically cleaning the electrostatic plate 35. Personnel only need to pull out the dust box 5 for cleaning regularly, which further simplifies the operation of personnel.

[0022] When in use, the motor 33 is controlled by a time relay, turned on at a set time, and switched to counterclockwise rotation after a certain period of clockwise rotation. After a period of counterclockwise rotation, it switches to clockwise rotation, and repeats continuously. When turned on, the motor 33 drives the threaded rod 31 to rotate, and the threaded rod 31 drives the threaded block 32 to reciprocate on the threaded rod 31, so that the threaded block 32 drives the electrostatic plate 35 to reciprocate. Since the rear end of the electrostatic plate 35 is fixed by the slider 39 and the slide rod 37, the electrostatic plate 35 always remains perpendicular to the threaded rod 31 during the reciprocating motion. The telescopic rod 34 is in the process of reciprocating motion. During the process, the wavy surface of the corrugated plate 38 pushes the telescopic end of the telescopic rod 34, so that the telescopic end of the telescopic rod 34 reciprocates back and forth, and the brush 36 fixed on the outer surface of the telescopic rod 34 reciprocates back and forth synchronously. The brush 36 continuously rubs the inner wall of the electrostatic plate 35, so that the electrostatic plate 35 generates static electricity, so that the electrostatic plate 35 can use static electricity to absorb dust on the surface of the touch screen 2 during the reciprocating movement, thereby achieving the effect of automatically and regularly removing dust from the surface of the touch screen 2. The dust removal method of electrostatic adsorption avoids the situation that wiping and cleaning will damage the surface of the touch screen 2 and the dust removal effect is not thorough.

[0023] When the bracket 43 moves to the right following the electrostatic plate 35, the metal block 46 arranged at the lower end of the bracket 43 will contact the sawtooth conductor 42 at the end of the movement trajectory. Since the sawtooth conductor 42 is connected to the grounding wire 41, when the bracket 43 contacts the sawtooth conductor 42, the static electricity of the electrostatic plate 35 will be eliminated. During the contact between the metal block 46 and the sawtooth conductor 42, the bracket 43 will continue to rise and then fall through the reset spring 44, so that the bracket 43 as a whole vibrates for a period of time. The flapper 45 on the bracket 43 vibrates and taps the upper surface of the electrostatic plate 35, so that the dust adsorbed by the electrostatic plate 35 falls into the dust box 5 below, thereby preventing the dust on the electrostatic plate 35 from falling back onto the touch screen 2, thereby achieving the effect of automatically cleaning the electrostatic plate 35. The personnel only need to pull out the dust box 5 for cleaning regularly, which further simplifies the operation of the personnel.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
