A transmission component is arranged inside the groove, and a cleaning component is arranged below the transmission component. A support plate A is arranged at the front end of the top plate, and a support plate B is welded to the rear end of the top plate. Through the transmission component, the cleaning component is driven to move back and forth, so as to clean the keyboard more thoroughly. The structure of the utility model is designed reasonably and compactly, and the use effect is good. By repeatedly cleaning the keyboard back and forth, the cleaning effect is enhanced, manpower is saved, and the work efficiency is improved." Another example is Chinese Patent CN212597263U, which discloses "a keyboard cleaning device for computers, including a box body and a motor. A box door is arranged on the box body. A motor is installed at one side of the bottom end of the box body. The motor is connected to a pulley I, and the pulley I is connected to a pulley II through a belt. A reciprocating lead screw is installed at the axis of the pulley II. The two ends of the reciprocating lead screw are rotationally connected to the inner wall of the box body through bearings. A movable block is installed on the reciprocating lead screw. A movable rod is welded to the lower end of the movable block, and a sliding rod is welded to the lower end of the movable rod. The sliding rod is slidably connected to a slide rail. When the distance between two fixing plates needs to be adjusted, rotate the adjusting screw rod to adjust the distance between the movable plate and the inner wall of the box body, so as to adjust the distance between the two fixing plates, which is suitable for fixing keyboards of different lengths and has a wider applicability." However, these two technologies are not suitable for household use. Therefore, there is a great demand for a small and household - suitable keyboard cleaning device. Summary of the Invention

[0041] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0042] This utility model provides an improved keyboard cleaning device for computers. The technical solution of this utility model is as follows:

[0043] like Figures 1-5 As shown, a computer keyboard cleaning device includes:

[0044] The housing 1 has a rotating shaft 4 rotatably mounted on its bottom, and the bottom of the rotating shaft 4 has a circular groove.

[0045] The cleaning component is slidably disposed within the circular groove.

[0046] Two damping sliders 14 are slidably disposed at the bottom of the housing 1, and a transmission plate 5 is provided at the bottom of each of the two damping sliders 14.

[0047] Connecting seat 6 is located at the bottom of the two transmission plates 5, and multiple through holes are opened at the bottom of the connecting seat 6;

[0048] The first brush 7 is located at the bottom of the connecting seat 6;

[0049] The negative pressure component is housed within the housing 1 and is connected to the connecting base 6.

[0050] The transmission component is set in the circular groove and is used to drive the connecting seat 6 to reciprocate.

[0051] Motor 13 is mounted on the inner wall of housing 1, and the output shaft and rotating shaft 4 of motor 13 are fixed.

[0052] During the rotation of the pivot 4, the connecting seat 6 is driven to move back and forth through the transmission component, which works with the first brush 7 to clean the surface of the keycaps. When the cleaning component slides out of the groove on the pivot 4, the smaller cleaning component is used to clean the gaps in the keyboard, thus improving the cleaning effect.

[0053] Because of its small size, this device can be used to clean keyboards by hand, making it more suitable for home use.

[0054] Furthermore, the transmission components include:

[0055] Electromagnet 17 is fixed on the inner wall of the top of the circular groove. A connecting block is slidably provided on the inner side wall of the circular groove. The cleaning component and the connecting block are fixed together.

[0056] Spring 18, one end of spring 18 is fixed to electromagnet 17, and the other end of spring 18 is fixed to connecting block;

[0057] Semi-elliptical plate 15, semi-elliptical plate 15 and connecting block are fixed;

[0058] Two transmission rods 16 are fixed to the side walls of two transmission plates 5 respectively.

[0059] When the switch of motor 13 is turned on, motor 13 drives the rotating shaft 4 to rotate.

[0060] When cleaning the keyboard surface, the switch of electromagnet 17 is turned on. Electromagnet 17 attracts the connecting block, causing the semi-elliptical plate 15 to be in a higher position. At this time, the rotating shaft 4 rotates, causing the semi-elliptical plate 15 to rotate. In conjunction with the action of the transmission rod 16, the transmission plate 5 is pushed to move. Through the two sets of transmission rods 16 and transmission plate 5, the connecting seat 6 is moved back and forth, which in turn drives the first brush 7 to move back and forth, thus cleaning the surface of the keycaps.

[0061] Furthermore, the cleaning components include:

[0062] Connecting rod 19, the connecting rod 19 is fixed to the bottom of the connecting block;

[0063] The second brush 8 is disposed on the side wall of the connecting rod 19.

[0064] When the switch of electromagnet 17 is turned off, the connecting block is pushed to move under the action of spring 18. During the movement of the connecting block, the semi-elliptical plate 15 is moved, so that the semi-elliptical plate 15 is no longer in contact with the transmission rod 16. With the action of damping slider 14, the connecting seat 6 is fixed. At the same time as the connecting block moves, the connecting rod 19 extends out of the circular groove of the rotating shaft 4, so that the second brush 8 extends out of the circular groove. The small second brush 8 is rotated to clean the gaps in the keyboard.

[0065] Furthermore, the negative pressure component includes:

[0066] Box 9, which is disposed through the inner wall of the top of the shell 1;

[0067] Filter 10 is disposed on the inner side wall of the box 9;

[0068] Air pump 11 is installed on the inner side wall of housing 1;

[0069] Connecting pipe 12, one end of which is installed through the bottom of box 9, and the other end of which is connected to the input port of air pump 11;

[0070] The hose 3 has one end inserted through the outer wall of the box 9 above the filter screen 10, and the other end of the hose 3 is connected to the connector 6.

[0071] When the air pump 11 is turned on and the cover 2 is closed, the air pump 11 creates negative pressure in the box 9 through the connecting pipe 12 and negative pressure in the connecting seat 6 through the hose 3, allowing outside air to enter the connecting seat 6 through the through hole. During the cleaning process, the dirt swept off enters the box 9 with the airflow and is then collected by the filter screen 10.

[0072] Furthermore, it also includes:

[0073] Cover 2 is hinged to the top of box 9.

[0074] Specifically, the working principle is as follows:

[0075] When in use, turn on the switch of the air pump 11 and close the cover 2. When the air pump 11 is working, it creates a negative pressure in the box 9 through the connecting pipe 12 and creates a negative pressure in the connecting seat 6 through the hose 3, so that the outside air enters the connecting seat 6 through the through hole. During the cleaning process, the dirt swept off enters the box 9 with the airflow and is then blocked by the filter screen 10 to achieve the collection of dirt.

[0076] When the switch of motor 13 is turned on, motor 13 drives the rotating shaft 4 to rotate.

[0077] When cleaning the keyboard surface, the switch of electromagnet 17 is turned on, and electromagnet 17 attracts the connecting block, so that the semi-elliptical plate 15 is in a higher position. At this time, the rotating shaft 4 rotates and drives the semi-elliptical plate 15 to rotate. With the action of the transmission rod 16, the transmission plate 5 is pushed to move. Through the two sets of transmission rods 16 and transmission plate 5, the connecting seat 6 is moved back and forth, which in turn drives the first brush 7 to move back and forth, so as to achieve the cleaning work of the keycap surface.

[0078] Next, remove the keycaps and clean the keyboard surface using the first brush 7, which moves back and forth.

[0079] After cleaning, the switch of electromagnet 17 is turned off. At this time, under the action of spring 18, the connecting block is pushed to move. During the movement of the connecting block, the semi-elliptical plate 15 is moved, so that the semi-elliptical plate 15 is no longer in contact with the transmission rod 16. With the action of damping slider 14, the connecting seat 6 is fixed. While the connecting block moves, the connecting rod 19 extends out of the circular groove of the rotating shaft 4, so that the second brush 8 extends out of the circular groove. The cleaning work of the keyboard gap is achieved by using the rotation of the smaller second brush 8.
