Description

Technical Field

[0001] This invention belongs to the field of keyboard cleaning technology, and in particular relates to a computer keyboard cleaning device. Background Technology

[0002] As the most commonly used and primary input device, the keyboard allows users to input English letters, Chinese characters, numbers, punctuation marks, etc., into the computer, thereby issuing commands and inputting data. Since keyboards are usually placed on the desktop, dust in the air and debris from fingers can easily fall onto the surface and crevices of the keyboard. If not cleaned for a long time, this can easily affect normal use.

[0003] Cleaning existing keyboards requires manual use of an air gun to reach into the gaps between the keys and blow out debris adhering to the keyboard surface or from the gaps, or removing the keys from the chassis for individual cleaning. This cleaning method is not only time-consuming and labor-intensive, but also has blind spots, and dust escapes during the blowing process. Summary of the Invention

[0022] Preferably, the intermittent pushing mechanism includes a toolbox arranged on the side of the frame, a drive shaft rotatably mounted on the toolbox, and a shaped wheel arranged on the drive shaft;

[0023] The outer side of the irregularly shaped wheel has multiple smooth arc surfaces in sequence, and the arc length of each smooth arc surface is equal.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0035] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0036] like Figure 1 - Figure 5 The diagram shows a structural representation of a computer keyboard cleaning device according to an embodiment of the present invention. The device includes a frame 1, a chassis 2, a dynamic clamping mechanism 100, a guiding mechanism 200, a blowing and suction mechanism 300, and an intermittent pushing mechanism 400. The chassis 2 is located at the bottom of the frame 1, and a key shaft 4 is mounted on the chassis 2, with a key 3 positioned at the top of the key shaft 4. Multiple sets of the dynamic clamping mechanism 100 are provided, symmetrically mounted on the inner wall of the frame 1. The movable ends of the dynamic clamping mechanisms 100 abut against both sides of the chassis 2 to clamp the chassis 2. The guiding mechanism 200 is rotatably mounted on the frame 1, and its bottom end is flush with the key. 3. The guide mechanism 200 is driven by an external forward and reverse motor 14 to facilitate pressing the buttons 3 one by one downwards; the blowing and dust-collecting mechanism 300 is arranged at the movable end of the guide mechanism 200. The blowing and dust-collecting mechanism 300 moves synchronously with the guide mechanism 200 and sprays gas between adjacent key shafts 4 to clean the dust adhering to their gaps and collect the dust; the intermittent pushing mechanism 400 is set on the side of the chassis 2. The outer side of the intermittent pushing mechanism 400 abuts against the chassis 2. The intermittent pushing mechanism 400 is also connected to the input end of the dynamic pressing mechanism 100 through a synchronous belt 23 to adjust its position during the process of cleaning dust on the chassis 2 and key shafts 4.

[0037] In the specific implementation of this embodiment, during the use of this cleaning device, the dynamic pressing mechanism 100 and the intermittent pushing mechanism 400 can intermittently adjust the position of the chassis 2 in the horizontal and vertical direction, adjusting one key at a time. In conjunction with the guiding mechanism 200 and the blowing and dust suction mechanism 300, the chassis 2, the key 3 and the key shaft 4 are cleaned row by row and key by key. No dead corners are left during the cleaning process, ensuring the cleaning quality while preventing dust from escaping.

[0038] In one embodiment of the present invention, when in use, the chassis 2 is fixed by the dynamic clamping mechanism 100. During the adjustment of the nozzle, the guide mechanism 200 also drives the intermittent pushing mechanism 400 to move through the synchronous belt 23, thereby pushing the chassis 2 to move horizontally and longitudinally. At the same time, the blowing and dust suction mechanism 300 cleans the dust on the chassis 2, the button 3 and the key shaft 4 and completes the dust collection.

[0039] like Figure 1 and Figure 2 As shown, in a preferred embodiment of the present invention, the dynamic clamping mechanism 100 includes a fixed rod 5 fixedly installed on the inner wall of the frame 1, a support ring 6 installed on the fixed rod 5, and a movable cylinder 7 slidably installed on the support ring 6.

[0040] The movable cylinder 7 is also provided with an elastic support 8, which is connected to the support ring 6 through a damper;

[0041] A rotating shaft 9 is rotatably mounted on the movable cylinder 7, and a roller 10 is also rotatably mounted on the rotating shaft 9.

[0042] In the specific implementation of this embodiment, when this application is used, the movable cylinder 7 is moved to both sides, the rotating shaft 9 and the roller 10 slide along the support ring 6, the elastic support member 8 undergoes elastic deformation under force, after the chassis 2 is placed on the frame 1, the elastic support member 8 restores its deformation, and the roller 10 is used to press against the chassis 2. When the chassis 2 moves under the push of the intermittent push mechanism 400, the roller 10 rotates along the rotating shaft 9, and the damper eliminates vibration.

[0043] like Figure 1 and Figure 3 As shown, in another preferred embodiment of the present invention, the guide mechanism 200 includes a positioning rod 11 fixedly installed on the inner wall of the frame 1 and a movable block 12 slidably installed on the positioning rod 11;

[0044] A drive component 13 is also rotatably mounted on the frame 1, and the drive component 13 is connected to the shaft end of an external forward and reverse motor 14 via a coupling.

[0045] The bottom end of the movable block 12 is symmetrically provided with extrusion chamfers 15.

[0046] In the specific implementation of this embodiment, when the forward and reverse motor 14 is working, it drives the drive component 13 to rotate through the coupling, thereby pushing the movable block 12 to slide along the positioning rod 11 in the horizontal direction. By adjusting the direction of the forward and reverse motor 14, the movement direction of the movable block 12 is adjusted. When the movable block 12 moves from one side of the chassis 2, the extrusion chamfer 15 contacts the button 3, and when the movable block 12 moves horizontally, the extrusion chamfer 15 presses down on the button 3.

[0047] like Figure 4 and Figure 5 As shown, in another preferred embodiment of the present invention, the blowing and dust-collecting mechanism 300 includes a fixed frame 16 symmetrically mounted on the movable end of the guide mechanism 200 and a nozzle disposed at the bottom end of the fixed frame 16.

[0048] The inner side of the fixing frame 16 is provided with a plurality of inner nozzles 19;

[0049] The fixed frame 16 is also provided with a flow channel 18, and the nozzle and the inner nozzle 19 are both connected to the flow channel 18.

[0050] In the specific implementation of this embodiment, a corrugated pipe 17 is installed on the side of the movable block 12 described in this application. One end of the corrugated pipe 17 is connected to an external air supply device, and the other end of the corrugated pipe 17 is connected to the flow channel 18. During the movement of the movable block 12, the fixed frame 16 moves synchronously, and during the movement, the gas flows along the corrugated pipe 17 and the flow channel 18 in sequence, and finally sprays out from the inner nozzle 19 and the nozzle.

[0051] like Figure 4 and Figure 5 As shown, in another preferred embodiment of the present invention, the blowing and dust collection mechanism 300 further includes a dust collection hood 20 installed at the movable end of the guide mechanism 200 and a suction nozzle 22 arranged at the bottom end of the dust collection hood 20.

[0052] The dust collection hood 20 has a chamber inside, and one end of the chamber is connected to an external corrugated pipe 21, which performs dust extraction under the action of the air extraction device.

[0053] In the specific implementation of this embodiment, while the dust is being cleaned by air jets, an external air extraction device is working. This device can draw outward-spreading dust into the dust collection hood 20 through the suction nozzle 22, where it flows within the chamber of the dust collection hood 20 and is eventually discharged outward, thereby preventing dust from polluting the environment during the cleaning process.

[0054] like Figure 1 and Figure 6As shown, in another preferred embodiment of the present invention, the intermittent pushing mechanism 400 includes a toolbox 24 arranged on the side of the frame 1, a drive shaft 25 rotatably mounted on the toolbox 24, and a shaped wheel 26 arranged on the drive shaft 25.

[0055] The outer side of the irregular wheel 26 has multiple smooth arc surfaces in sequence, and the arc length of each smooth arc surface is equal.

[0056] The smooth arc surface includes smooth arc surface one 27, smooth arc surface two 28, smooth arc surface three 29, smooth arc surface four 30, smooth arc surface five 31 and smooth arc surface six 32;

[0057] The smooth arc surface 1 27 and smooth arc surface 28, the smooth arc surface 28 and smooth arc surface 3 29, the smooth arc surface 3 29 and smooth arc surface 4 30, the smooth arc surface 4 30 and smooth arc surface 5 31, and the smooth arc surface 5 31 and smooth arc surface 6 32 are all connected by transition slopes 33.

[0058] In the specific implementation of this embodiment, the forward and reverse motor 14 and the toolbox 24 are both electrically connected to an external controller. The toolbox 24 is equipped with a switching unit, such as a telescopic component pushing a meshing gear, so that the drive component 13 completes an arc surface switch during forward and reverse rotation, driving the chassis 2 to move. When the drive component 13 rotates, it drives the toolbox 24 to work through the set synchronous belt 23, which in turn drives the transmission shaft 25 and the irregular wheel 26 installed on the transmission shaft 25 to rotate synchronously. So that when the movable block 12 moves horizontally from one end of the chassis 2 to the other end, the irregular wheel 26 rotates and pushes the chassis 2 to move horizontally longitudinally when it passes the transition slope 33. This is repeated to adjust the position of the chassis 2 and the button 3.

[0059] In summary, during use, moving the movable cylinder 7 to both sides causes the rotating shaft 9 and roller 10 to slide along the support ring 6. The elastic support 8 undergoes elastic deformation under force. After the chassis 2 is placed on the frame 1, the elastic support 8 returns to its original deformation, and the roller 10 provides a clamping action on the chassis 2. Vibration is eliminated by the damper. When the forward and reverse motor 14 is working, it drives the drive component 13 to rotate through the coupling, thereby pushing the movable block 12 to slide horizontally along the positioning rod 11. The forward and reverse motor 14 can be adjusted to achieve this. The direction of movement of the movable block 12 is adjusted by the steering of the movable block 12. When the movable block 12 moves from one side of the chassis 2, the extrusion chamfer 15 contacts the button 3. During the translation of the movable block 12, the extrusion chamfer 15 presses down on the button 3. The drive component 13 rotates and drives the toolbox 24 to work through the synchronous belt 23, thereby driving the transmission shaft 25 and the irregular wheel 26 mounted on the transmission shaft 25 to rotate synchronously. This is so that when the movable block 12 moves horizontally from one end of the chassis 2 to the other end, the... When the irregularly shaped wheel 26 rotates over the transition slope 33, it pushes the chassis 2 to move horizontally and longitudinally. This process is repeated to adjust the position of the chassis 2 and the button 3. During the movement of the movable block 12, the fixed frame 16 moves synchronously. During the movement, the gas flows sequentially along the bellows 17 and the flow channel 18, and finally is sprayed out from the inner nozzle 19 and the nozzle, blowing the dust attached to the chassis 2, button 3 and key shaft 4 outward. The external air extraction device works to suck the outward dust into the dust collection hood through the suction nozzle 22. 20, and flows within the chamber inside the dust collection hood 20. During use, this cleaning device, through the dynamic pressing mechanism 100 and the intermittent pushing mechanism 400, can intermittently adjust the horizontal and vertical position of the chassis 2, adjusting one key at a time. Combined with the guiding mechanism 200 and the blowing and suction mechanism 300, it achieves row-by-row, key-by-key cleaning of the chassis 2, buttons 3, and key shafts 4, leaving no dead corners during cleaning. While ensuring cleaning quality, it prevents dust from escaping and polluting the environment during cleaning.

[0060] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
