Description

Screen and keyboard dual-purpose cleaning device

technical field

The utility model relates to a cleaning device, in particular to a dual-purpose cleaning device for a screen and a keyboard, which can be used for cleaning the screen and the keyboard at the same time.

Background technique

According to general screens such as TV screens, computer screens, monitor screens, etc., after a period of use, the surface of the screen will absorb foreign objects such as dust particles due to factors such as static electricity, or adhere to them due to user contact. Stains such as grease and dirt affect the clarity of these screens and reduce viewing quality.

According to general keyboards such as computer keyboards, cash register keyboards, computer keyboards, etc., the structure is usually provided with a plurality of rows of neatly arranged buttons on a plate body, with appropriate gaps between adjacent buttons so as not to interfere with each other. The pressing operation of the button.

As far as the top view is concerned, since the keys of the keyboard and the gaps between them face upward, after a period of use, dust particles in the air tend to accumulate on these keys and the gaps, and the user accidentally drops them when using or eating. Dropped small objects or such as rice grains and loose food are also easy to accumulate on the keys and the gaps, causing the keyboard to be dirty and even affecting the operation of the keyboard.

That is to say, the screen and the keyboard are objects that are easy to hide dirt, and it is necessary to clean them regularly or irregularly to keep the screen clear and the keyboard clean.

For the cleaning of the screen, conventionally, a cleaning cloth is used to wipe the surface of the screen to remove dust and dirt. For the cleaning of the keyboard, the surface of each button of the keyboard is usually cleaned with a cleaning cloth; for the cleaning of the gap, a sharp elongated object such as a pen tip is used to cover the cleaning cloth, and then inserted into the Wipe back and forth in the gap to remove dust and dirt.

However, when simply cleaning the surface of the screen or keyboard with a cleaning cloth, or cleaning the gap between the keyboard with a slender object, it has the following obvious shortcomings in use:

(1). The cleaning cloth is a sheet-like object, which is difficult to hold and apply force in the cleaning operation;

(2). During the cleaning operation, due to the concave-convex configuration of the user's hand, the contact force between the cleaning cloth and the screen surface will be uneven, so that various parts of the screen surface will be cleaned unevenly;

(3). In addition, for the cleaning of the keyboard, the surface of the keyboard keys is not flat, and the surface of the keys and the surrounding sides are multi-angle changes; the existing sheet-like cleaning cloth cannot clean the various parts of the keys. not effectively;

(4). For the cleaning of the key gap, it must be supplemented with slender objects, which is inconvenient to use;

(5). For the cleaning of the key gap, it is impossible to find a corresponding slender object; that is, if the slender object is too thick, it cannot be inserted into the key gap; if the slender object is too sharp, it may be damage to the keyboard.

Due to the above reasons, the applicability of existing keyboard cleaning elements is poor.

According to the structure of the second protruding unit 5, the pivot hole seat 53 can rotate on the pivot 52, and drive the second brush body unit 3 to rotate in an arc through the opening 51, so that the second brush body unit 3 can rotate in an arc. The second bristle body 32 protrudes outward from the second port 15 or is accommodated in the second accommodating chamber 16 .

The cleaning device of the present invention further includes a cover body 6 corresponding to the opening 51 to cover the opening 51 in normal times to prevent the intrusion of dust and foreign matter. The cover body 6 has an inner end portion 61 and an outer end portion 62 opposite to each other, and a joint hole 611 is formed through the inner end portion; and the inner wall of the second side portion 18 of the housing 1 is provided at a position corresponding to the joint hole There is a pivot tip 63, which is pivotally connected with the coupling hole 611. Therefore, the cover body 6 can be rotated by the pivot pin 63 as an axis, so that the cover body 6 is covered on the opening 51 to cover the opening; or it can be opened from the opening 51 for the second brush body unit 3 and The second protrusion unit 5 is used through this port.

The bottom edge 151 of the second port 15 and the top edge 621 of the outer end 62 of the cover body 6 match the outer circumference of the connecting rod portion 531 of the second retracting unit 5, when the second brush unit 3 is turned out for use At this time, the above-mentioned bottom edge 151 and top edge 621 can clamp the connecting rod portion 531 together, so that the second brush body unit 3 maintains a stable use state.

Also, as shown in Figure 5, the inner surface of the cover body 6 is provided with a baffle plate 64, and the pivot hole seat 53 is provided with a groove 534 corresponding to the baffle plate; When the body 6 is covered, the baffle plate 6 can just be inserted into the groove 534 to fix the position of the pivot hole seat 53, that is, to fix the position of the second brush body unit 3, thus making the second brush body unit 3 remain stable. status of use.

In addition, the cover 6 and the housing 1 are provided with at least one fastening unit 7, the fastening unit includes a buckle 71 which is arranged on the outer wall of the cover 6, and a buckle groove 72 which is arranged on the inner wall of the housing 1 and Corresponding to the position of the button body 71 , it is fastened with the button body to maintain a stable covering relationship between the cover body 6 and the housing 1 .

When using the screen and keyboard dual-purpose cleaner of the present utility model, when wanting to clean the screen, the user only needs to hold the housing 1, and then use the first retracting unit 4 to move the first brush body unit 2 through the first port 13 to Push out so that the first bristle body 22 protrudes from the outside of the first port 13 (as shown in Figure 4), that is, the first bristle body 22 contacts the screen surface, and brushes back and forth to remove the dirt on the screen surface. Dust and dirt, to achieve the effect of cleaning the surface of the screen. Similarly, when the keyboard is to be cleaned, the second brush body unit 3 is turned out through the opening 51 and the second port 15 with the second protruding unit 5, so that the second bristle body 32 protrudes from the second port 15 (as shown in FIG. 5 ), that is, the second bristle body 32 contacts the keyboard surface and the gap thereof, and brushes back and forth to remove dust and dirt on the keyboard to achieve the effect of cleaning the keyboard. If when cleaning the screen and the keyboard at the same time, as long as the first brush body unit 2 and the second brush body unit 3 are pushed out or turned out (as shown in Figure 2 ), the protruding first bristle body 22 and The second bristle body 32 cleans the screen and the keyboard.

When the cleaning device of the present utility model is not used normally, in order to prevent the first brush body unit 2 and the second brush body unit 3 from being polluted, the first brush body unit and the second brush body unit can be respectively passed through the first retracting unit. 4 and the second protruding unit 5 are accommodated in the first accommodation chamber 14 and the second accommodation chamber 16, and the cover body 6 is covered on the port 51 (as shown in Figure 1), which not only has dustproof and The function of protecting the first and second brush body units can be reduced at the same time so as to facilitate carrying and normal storage.
