Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand, the present invention will be further explained below with reference to the following embodiments and the accompanying drawings, but the following embodiments are only the preferred embodiments of the present invention, and not all embodiments are included. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative work belong to the protection scope of the present invention.

Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

Example 1

As shown in fig. 1-3, the dust-absorbing eraser comprises an eraser 1, wherein the eraser 1 is arranged in a dust-absorbing assembly 2, extends outwards relative to the dust-absorbing assembly 2 and is used for contacting with a friction surface; the dust collection assembly 2 comprises a handle 23, a rubber cavity 22 is arranged in the handle 23, the rubber 1 is inserted into the rubber cavity 22, a pressing piece 21 is arranged on the outer wall of the handle 23 beside the rubber 1, the pressing piece 21 is fixed at the handle 23 and extends into the rubber cavity 22 to be contacted with the rubber 1;

be equipped with in the handle 23 and inhale row chamber 26, inhale row chamber 26 in rubber chamber 22 side, be used for holding the rubber bits, inhale row chamber 26 upside is equipped with miniature dust absorption unit 25, miniature dust absorption unit 25 inserts and inhales row chamber 26 port up, miniature dust absorption unit 25 below is equipped with lug 28, lug 28 is fixed in inhaling row chamber 26 inner wall, lug 28 opposite side is being located handle 23 outer wall and is being equipped with holding back 27, holding back 27 is fixed in handle 23 department, and stretch into with lug 28 formation separation piece to inhaling row chamber 26, dust absorption assembly 2 still includes the battery chamber, be equipped with battery 24 in the battery chamber, battery 24 is located same end with miniature dust absorption unit 25, and with miniature dust absorption unit 25 looks electrical connection.

The suction and discharge chamber 26 is divided into two by the blocking member formed by the protrusion 28 and the interception member 27, wherein the suction and discharge chamber 26 is a complete chamber when the interception member 27 moves inwards, and the suction and discharge chamber 26 is divided into two chambers after the interception member 27 is reset.

The inner wall of the rubber cavity 22 is adhered with rubber skin which is abutted against the rubber 1.

The suction and discharge chamber 26 is a chamber configuration in which a cylindrical chamber, which is a mounting chamber of the micro dust suction unit 25, and a tapered chamber are combined.

In this embodiment, the eraser 1 is arranged in the dust collection assembly 2, and when the original wiping effect is satisfied, the micro dust collection unit 25 arranged inside generates high-flow-rate air flow to adsorb eraser crumbs generated in wiping, so that the problem that the eraser crumbs fall everywhere, the operation surface is unclean, and the use limitation such as writing is affected is avoided.

In this embodiment, rubber 1 is arranged in rubber chamber 22, and is inconsistent with the attached rubber of cavity inner wall, namely, through the friction dynamics that produces in the contact between the object, avoids rubber 1 in wiping, because of producing the slip for the cavity, the uneven problem of the dynamics of wiping that leads to through setting up pressing member 21 in handle 23 department, and then when pressing member 21 transmits the pressing dynamics to rubber 1, more firm fixes rubber 1 position.

In this embodiment, the lug 28 and the blocking member formed by the blocking member 27 divide the suction cavity 26 into two parts, that is, when sucking and discharging the eraser crumbs, the blocking member 27 moves closer to the lug 28, so that the blocked cavity is complete, and thus the high-flow airflow is conveniently sucked and discharged in the cavity, the eraser crumbs are adsorbed, and after adsorption, the blocking member 27 resets (moves away from and forms the blocking state) relative to the lug 28, and the adsorbed eraser crumbs are placed in the cavity near the micro dust collection unit 25, so as to avoid the problem that the eraser crumbs are left in the cavity when the handle 23 is forced to move in a non-directional manner.

In this embodiment, the interception member 27 and the micro dust collection unit 25 are adaptive structures, that is, when the interception member 27 is forced to move into the suction and discharge cavity 26, the micro dust collection unit 25 is powered on and is in a running state; in contrast, when the trap 27 is reset, the micro dust suction unit 25 is powered off to be in a standby state.

In the present disclosure, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact between the first and second features, or may comprise contact between the first and second features not directly. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention.
