Description

Technical Field

[0001] This utility model relates to the field of keyboard dust removal technology, and in particular to a multifunctional dust removal device for keyboards. Background Technology

[0002] A keyboard is a device for inputting instructions and data to operate computer equipment. It also refers to a set of function keys arranged by a system to operate a machine or device, such as a typewriter or computer keyboard. During use, impurities can accumulate on the surface of a keyboard, thus requiring the use of dust removal equipment to clean it.

[0003] According to the search, the Chinese patent "A dust removal device for a keyboard" authorized announcement number "CN219648150U" achieves the function of scraping the keyboard and adsorbing the scraped impurities into the collection drawer by using a dust removal box, a mounting box, an air inlet at the lower end of the mounting box, a first brush, and a dust removal fan.

[0004] In the aforementioned application, because the air inlet is located at the lower end of the mounting box surface, the suction is strong near the air inlet of the keyboard and weaker away from the air inlet, which in turn affects the dust removal effect on the keyboard.

[0005] Therefore, a multifunctional dust removal device for keyboards is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a multi-functional dust removal device for keyboards to solve the above-mentioned problems, thereby improving the issue of strong suction near the air inlet and weak suction away from the air inlet.

[0007] This utility model achieves the above-mentioned objectives through the following technical solution: a multi-functional dust removal device for keyboards, comprising: a dust removal cylinder, wherein an exhaust fan is provided inside the dust removal cylinder; a dust removal mechanism, wherein the dust removal mechanism includes a suction pipe snapped onto the inner wall of the dust removal cylinder, a brush ring fixedly connected to the surface of the suction pipe, a rubber filter screen provided on the inner wall of the dust removal cylinder, the surface of the rubber filter screen being frustoconical, and a sealing ring fixedly connected to one end of the suction pipe, the surface of the sealing ring abutting against the inner wall of the dust removal cylinder. Through the dust removal cylinder, exhaust fan, suction pipe, and brush ring, the keyboard is thoroughly scraped and all impurities are absorbed after scraping, thus ensuring the dust removal effect on the keyboard. The rubber filter screen prevents impurities inside the dust removal cylinder from adhering to the surface of the exhaust fan, and the sealing ring seals the connection between the suction pipe and the dust removal cylinder, thus ensuring the dust removal effect of the dust removal cylinder.

[0008] Preferably, a scraper ring is slidably connected to the inner wall of the suction tube, and two first springs are fixedly connected to the opposite ends of the brush ring and the scraper ring. The scraper ring cleans the bristles on the brush ring, facilitating the removal of impurities attached to the bristles, ensuring the cleanliness of the brush ring, and thus guaranteeing the effective scraping of the keyboard by the brush ring.

[0009] Preferably, an anti-slip pad is fixedly connected to the lower end of the surface of the dust collector. The anti-slip pad enhances the stability and comfort of holding the dust collector.

[0010] Preferably, the upper and lower ends of the inner wall of the dust collector are slidably connected to anti-shifting rods, the surface of the anti-shifting rods is engaged with the inner wall of the suction pipe, the top end of the anti-shifting rods is fixedly connected to a second spring, and the other end of the second spring is fixedly connected to the inner wall of the dust collector.

[0011] Preferably, a connecting rope is fixedly connected to the top of the anti-shifting rod, and the other end of the connecting rope passes through the dust collection cylinder and is fixedly connected to an arc-shaped block. Through the connecting rope and the arc-shaped block, the anti-shifting rod can be pulled away from the dust collection pipe, thereby facilitating the opening of the dust collection cylinder and the removal of impurities inside.

[0012] Preferably, two sliders are fixedly connected to the surface of the rubber filter screen.

[0013] Preferably, the inner wall of the dust collector cylinder has two recessed holes, and the surface of the slider is slidably connected to the inner wall of the recessed holes. Through the slider and the recessed holes, precise guidance and restriction are achieved for the position of the rubber filter screen as it slides into the dust collector cylinder.

[0014] The beneficial effects of this utility model are:

[0015] 1. By using a dust collection cylinder, exhaust fan, suction pipe, and brush ring, the keyboard is thoroughly scraped and all impurities are absorbed. Compared to existing methods that do not thoroughly clean the keyboard, this method uses a moving dust collection cylinder to clean the keyboard completely, thus ensuring effective dust removal. A rubber filter prevents impurities in the dust collection cylinder from adhering to the surface of the exhaust fan, and a sealing ring seals the connection between the suction pipe and the dust collection cylinder, thereby ensuring the effective dust collection of the dust collection cylinder.

[0016] 2. The scraping ring cleans the bristles on the brush ring, making it easier to remove impurities attached to the bristles, ensuring the cleanliness of the brush ring, and thus ensuring the effective scraping of the keyboard by the brush ring. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In practical implementation: such as Figure 1-4 As shown, a multifunctional dust removal device for keyboards includes: a dust removal cylinder 1, with an exhaust fan 2 inside; a dust removal mechanism 3, including a suction pipe 31 snapped onto the inner wall of the dust removal cylinder 1, a brush ring 32 fixedly connected to the surface of the suction pipe 31, a rubber filter screen 33 provided on the inner wall of the dust removal cylinder 1, the surface of the rubber filter screen 33 being frustoconical, and a sealing ring 34 fixedly connected to one end of the suction pipe 31, the surface of the sealing ring 34 abutting against the inner wall of the dust removal cylinder 1. The surface of the rubber filter screen 33 is tightly attached to the inner wall of the dust removal cylinder 1. The sealing ring 34 is a silicone component.

[0024] When the keyboard needs to be dusted, fully charge the dust collection cylinder 1 using the corresponding data cable. Hold the bottom of the dust collection cylinder 1 and place the bristles on the brush ring 32 against the keyboard. Press the switch button on the dust collection cylinder 1 to power on the exhaust fan 2, which will then start rotating. The exhaust fan 2 typically has a suction power of about 10,000-15,000 Pa, which has a good adsorption effect on common impurities such as dust, hair, and cookie crumbs found in keyboard crevices. It can remove impurities without damaging the keyboard due to excessive suction. This causes the air inside the dust collection cylinder 1 to be expelled, creating a negative pressure inside the dust collection cylinder 1 and generating suction. Move the dust collection cylinder 1 back and forth so that the bristles on the brush ring 32 move back and forth on the keyboard, scraping away the impurities. The suction tube 31 then picks up the scraped impurities and transports them into the dust collection cylinder 1. At this time, the rubber filter 33 prevents impurities from adhering to the exhaust fan 2, thus scraping and vacuuming the keyboard, and performing multi-functional dust removal.

[0025] like Figure 2-3 As shown, a scraper ring 35 is slidably connected to the inner wall of the suction pipe 31, and two first springs 36 are fixedly connected to the opposite end of the brush ring 32 and the scraper ring 35. The bristles on the brush ring 32 are made of nylon.

[0026] After the keyboard is cleaned, the bristles on the brush ring 32 move away from the keyboard. At this time, push the scraper ring 35 to move the inner wall of the scraper ring 35 on the bristles of the brush ring 32, thereby removing the bristles attached to the brush ring 32.

[0027] like Figure 2 As shown, an anti-slip pad 37 is fixedly connected to the lower end of the surface of the dust collector 1. The anti-slip pad 37 is a rubber component.

[0028] like Figure 4 As shown, anti-shifting rods 310 are slidably connected to the upper and lower ends of the inner wall of the dust collector 1. The surface of the anti-shifting rod 310 is snapped into the inner wall of the suction pipe 31. A second spring 311 is fixedly connected to the top end of the anti-shifting rod 310. The other end of the second spring 311 is fixedly connected to the inner wall of the dust collector 1. A connecting rope 312 is fixedly connected to the top end of the anti-shifting rod 310. The other end of the connecting rope 312 passes through the dust collector 1 and is fixedly connected to an arc-shaped block 313. Two sliders 39 are fixedly connected to the surface of the rubber filter screen 33. Two recesses 38 are opened in the inner wall of the dust collector 1. The surface of the sliders 39 is slidably connected to the inner wall of the recesses 38.

[0029] When it is necessary to clean the impurities in the dust collector 1, pull the arc block 313 to move the two connecting ropes 312, thereby moving the anti-shift rod 310 away from the suction pipe 31. Pull the suction pipe 31 to move the sealing ring 34 away from the inner wall of the dust collector 1, thereby opening one end of the dust collector 1. At this time, the impurities inside the dust collector 1 are discharged. Pull the rubber filter screen 33 to move the slider 39 away from the concave hole 38, thereby cleaning the rubber filter screen 33.

[0030] After cleaning, slide the rubber filter screen 33 into the dust collection cylinder 1, and move the slider 39 in the concave hole 38. After the rubber filter screen 33 slides into the appropriate position in the dust collection cylinder 1, snap the suction pipe 31 into the dust collection cylinder 1, so that the surface of the sealing ring 34 is tightly attached to the dust collection cylinder 1. Loosen the arc block 313, and the elastic force of the second spring 311 pushes the anti-shift rod 310 down, so that the anti-shift rod 310 is snapped into the suction pipe 31, thereby installing the suction pipe 31 on the dust collection cylinder 1.

[0031] When using this invention, hold the anti-slip soft pad 37, place the bristles on the brush ring 32 against the keyboard, and press the switch button on the dust removal cylinder 1 to power on the exhaust fan 2. The exhaust fan 2 will then start rotating, causing the air inside the dust removal cylinder 1 to be expelled. This creates a negative pressure inside the dust removal cylinder 1, generating suction. Moving the dust removal cylinder 1 back and forth causes the bristles on the brush ring 32 to move back and forth on the keyboard, scraping away impurities. The suction tube 31 then picks up and transports the scraped impurities into the dust removal cylinder 1. At this time, the rubber filter 33 prevents impurities from adhering to the exhaust fan 2, thus scraping and vacuuming the keyboard, thereby performing multi-functional dust removal on the keyboard.

[0032] It should be noted that the dust collector 1, exhaust fan 2 and suction pipe 31 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the dust collector 1 and exhaust fan 2 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
