Abstract
Description
Technical Field
[0001] This utility model relates to the field of computer keyboard technology, and in particular to a computer keyboard with a dust removal function. Background Technology
[0002] As an important input device for human-computer interaction, computer keyboards easily accumulate dust, debris, and other contaminants during daily use, especially in the gaps between the bottom of the keycaps and the top surface of the keyboard body, which are difficult to clean thoroughly with conventional cleaning methods. Long-term dust accumulation not only affects the keyboard's appearance but can also lead to problems such as key sticking and poor contact, shortening the keyboard's lifespan.
[0003] Traditional keyboard cleaning methods typically involve using a brush, vacuuming, or directly removing the keycaps. However, brushes and vacuum cleaners are often ineffective at removing stubborn dust from the bottom of the keycaps, and frequent keycap removal is not only tedious but can also damage the mechanical switches or the keycap structure.
[0004] Therefore, there is an urgent need for a computer keyboard that can efficiently remove dust from the bottom of the keycaps and the keyboard surface without disassembling the keycaps, in order to improve cleaning efficiency and extend the life of the keyboard. Utility Model Content
[0005] The technical solution is as follows: A computer keyboard with a dust removal function includes a keyboard body, mechanical switches, keycaps, a ventilation box, a fan, and air ducts. Keycaps are detachably mounted on the top of the keyboard body via the mechanical switches. A ventilation box with a cavity is provided on one side wall of the keyboard body in the width direction. A fan is installed inside the ventilation box. An air duct is provided between two adjacent rows of keycaps on the top of the keyboard body. The air duct is located below the keycaps and protrudes from the top surface of the keyboard body with separate air duct holes. The air duct holes are angled towards the bottom of the keycaps. The air duct is connected to the cavity inside the ventilation box. When the fan is working, it sprays air through the air duct holes to remove dust from the top surface of the keyboard body and the bottom of the keycaps.
[0006] Furthermore, it also includes a closed tube, which is rotatably installed inside the air guide tube. The closed tube has a ventilation opening that is compatible with the ventilation hole on the air guide tube. When the ventilation opening is misaligned with the ventilation hole, the closed tube blocks the ventilation hole on the air guide tube.
[0007] Furthermore, the end of the closed tube away from the ventilation box is the handle end, and the outer wall of the handle end is provided with grooves evenly spaced along its circumference.
[0008] Furthermore, mounting bases are symmetrically arranged on the side wall of the keyboard body away from the ventilation box. A locking plate is slidably arranged on both mounting bases. The locking plate has a sliding groove adapted to the mounting base. An elastic element is arranged in the sliding groove. The locking plate has an arc-shaped locking groove for locking the grip stick.
[0009] Furthermore, it also includes a hinge, a storage plate, and a cleaning brush. The storage plate is mounted on the bottom of the keyboard body via a hinge, and the cleaning brush is detachably mounted on the storage plate.
[0010] Furthermore, a torsion spring is provided between the storage plate and the keyboard body, and the torsion spring is wound around the pivot.
[0011] Furthermore, the keyboard body has symmetrical supports at its bottom.
[0012] The beneficial effects of this utility model are as follows: 1. Through the combination of a fan, air duct and air duct hole, the high-speed airflow can directly blow the gap between the bottom of the keycap and the top surface of the keyboard, effectively removing the accumulated dust, avoiding the tedious operation of disassembling the keycap in the traditional cleaning method, and improving cleaning efficiency.
[0013] 2. The rotating design of the closed tube allows for flexible control of the opening or closing of the air guide hole, blocking airflow when cleaning is not required and preventing foreign objects from entering the inner cavity of the air guide tube.
[0014] 3. The design of the card plate and the arc-shaped card slot can prevent the closed tube from rotating accidentally, ensuring that the air guide hole remains open in the cleaning mode and closed in the non-cleaning mode, thus improving the reliability of use.
[0015] 4. The design of the storage plate and cleaning brush makes it easy for users to manually remove stubborn dust, especially the dust accumulated on the sides of the keycaps or the surface of the air duct, further optimizing the cleaning effect; at the same time, it makes the cleaning brush easy to carry.

[0023] The present invention will now be described in detail with reference to the accompanying drawings.
[0024] Example: A computer keyboard with a dust removal function, such as... Figures 1-5 As shown, the keyboard includes a keyboard body 1, mechanical switches 2, keycaps 3, a ventilation box 4, a fan 5, and an air duct 6. Keycaps 3 are detachably mounted on the top of the keyboard body 1 via the mechanical switches 2. The mechanical switches 2 are connected to the PCB board via metal pins / contacts, and have cross-shaped / box-shaped stem slots on the top. Keycaps 3 have cross-shaped posts (or other structures) at the bottom that match the stem, and are fixed to the stem by pressing down. A ventilation box 4 with a cavity is provided on one side wall of the keyboard body 1 in the width direction. A fan 5 is installed inside the body 4. A duct 6 is provided between the two adjacent rows of keycaps 3 on the top of the keyboard body 1. The duct 6 is located below the keycaps 3. When the fan 5 is working, the airflow enters the duct 6 from the cavity of the ventilation box 4. The duct 6 protrudes from the top surface of the keyboard body 1 and is provided with separate air duct holes. The air duct holes are obliquely facing the bottom of the keycaps 3. The duct 6 is connected to the inner cavity of the ventilation box 4. When the fan 5 is working, the high-speed airflow is ejected through the air duct holes on the duct 6, thereby blowing away the dust on the bottom of the keycaps 3 and the top surface of the keyboard body 1.
[0025] When the keyboard needs cleaning, turn on the fan 5 inside the ventilation box 4. The airflow enters the air duct 6 from the cavity of the box. The high-speed airflow is ejected through the air duct holes on the air duct 6. The airflow directly blows the gap between the bottom of the keycap 3 and the top surface of the keyboard, blowing away the accumulated dust. The dust is dispersed outward from the gap of the keycap 3 with the airflow, thereby cleaning the bottom of the keycap 3 and the top surface of the keyboard body 1. This achieves the effect of cleaning the keycap 3 and the top surface of the keyboard body 1 without disassembling the keycap 3.
[0026] like Figures 3-5As shown, it also includes a closed tube 7. The closed tube 7 is rotatably installed inside the air guide duct 6. The closed tube 7 has a vent that is adapted to the ventilation hole on the air guide duct 6. When the vent is misaligned with the ventilation hole, the closed tube 7 blocks the ventilation hole on the air guide duct 6. In use, rotating the closed tube 7 aligns the vent with the ventilation hole, allowing airflow to pass normally. Rotating the closed tube 7 misaligns the vent, and the wall of the closed tube 7 blocks the ventilation hole, blocking the airflow. This prevents foreign objects from entering the air guide duct 6 when not cleaning dust. In addition, by rotating the closed tube 7, the size of the ventilation hole can be adjusted, thereby adjusting the size of the ejected airflow and the pressure of the airflow ejected from the ventilation hole, so as to clean dust more efficiently.
[0027] Furthermore, the end of the closed tube 7 away from the ventilation box 4 is the handle end, and the outer wall of the handle end is provided with grooves 16 evenly spaced along its circumference. The grooves 16 help to increase the friction between the user's hand and the handle end, thereby rotating the closed tube 7 more efficiently.
[0028] When cleaning is not required, rotate the closing tube 7 by holding the handle end of the closing tube 7, thereby misaligning the vent on the closing tube 7 with the air guide hole on the air guide 6, thus blocking the air guide hole on the air guide 6, blocking the airflow, and preventing foreign objects from entering the inner cavity of the air guide 6.
[0029] like Figure 4 As shown, mounting bases 8 are symmetrically arranged on the side wall of the keyboard body 1 away from the ventilation box 4. A locking plate 9 is slidably arranged on both mounting bases 8. The locking plate 9 has a sliding groove adapted to the mounting base 8. The mounting bases 8 move relative to each other in the sliding groove. An elastic element 10 is arranged in the sliding groove. The two ends of the elastic element 10 are respectively connected to the top wall of the sliding groove and the top surface of the mounting base 8. The elastic element 9 is used to reset the locking plate 9 upward. The locking plate 9 has an arc-shaped locking groove for locking the grip lever.
[0030] When the closed tube 7 is rotated to the target position, the force pressing on the clamping plate 9 is released, so that the arc-shaped groove on the clamping plate 9 is engaged with the handle end of the closed tube 7, thereby preventing the closed tube 7 from rotating accidentally.
[0031] like Figure 6 As shown, it also includes a hinge 11, a storage plate 12 and a cleaning brush 13. The storage plate 12 is rotatably mounted on the bottom of the keyboard body 1 via the hinge 11. The cleaning brush 13 is detachably mounted on the storage plate 12. The cleaning brush 13 is used to manually remove dust from the top surface of the keyboard body 1.
[0032] Furthermore, a torsion spring 14 is provided between the storage plate 12 and the keyboard body 1. The torsion spring 14 is wound around the pivot 11 and is used to drive the storage plate 12 to rotate and reset so that the storage plate 12 remains in close contact with the bottom of the keyboard body 1.
[0033] When the cleaning brush 13 is needed, rotate the storage plate 12 downwards to remove the cleaning brush 13 from the storage plate 12. Use the cleaning brush 13 to manually remove stubborn dust that has not been completely blown away by the airflow, especially on the sides of the keycaps 3 or the surface of the air duct 6. After using the cleaning brush 13, put the cleaning brush 13 back on the storage plate 12. The torsion spring 14 will reset the storage plate 12 to the bottom of the keyboard body 1, thus achieving the effect of convenient access to the cleaning brush 13.
[0034] like Figure 6 As shown, a bracket 15 is symmetrically arranged at the bottom of the keyboard body 1. The tilt angle of the keyboard body 1 can be adjusted by the bracket 15 to ensure uniform airflow distribution during dust cleaning and adapt to different usage scenarios.
[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
