Description

Technical Field

[0001] The utility model belongs to the technical field of dust-removing duster structures, in particular to a dust-removing duster. Background Art

[0002] At present, there are many types of dust dusters on the market. The dust duster includes a main body and a dust removal sleeve. The main body includes a handle. A flat plate is provided at the front end of the handle. The dust removal sleeve is mounted on the flat plate for cleaning. The above-mentioned dust duster is suitable for cleaning angle positions and plane positions, but is not conducive to cleaning arc surface positions and other special positions. Therefore, the defects of the dust duster are more obvious and bring many inconveniences to users.

[0003] Therefore, adjustable dust dusters have appeared on the market, such as Chinese patent 202320609258.6, which discloses a dust duster comprising a main body and a dust cover, wherein the main body comprises a handle and a dust collection frame arranged at the front end of the handle, and the dust collection frame is mounted on the dust collection frame for cleaning; the characteristic is that the dust collection frame comprises a rotating frame and a main frame, the rotating frame and the main frame are rotatably connected, when the rotating frame rotates to the same angle relative to the main frame, the dust collection frame is in a flat state, and when the rotating frame rotates to different angles relative to the main frame, the dust collection frame is in an extended state; since the dust collection frame of the utility model has a transformable form, the dust collection cover can be transformed between a flat state and an extended state, so that the dust duster is suitable for cleaning in various environments. In order to make the dust duster have a faster cleaning effect, the duster body is longer, so the rotating frame is longer. The rotating frame is a ring-shaped part, and the rotating frame formed by processing is easy to twist and deform. The rotating seats at the upper and lower ends of the rotating frame need to be coaxially set, and there are coaxiality requirements. Therefore, the production and processing accuracy of the rotating frame is required to be high. After long-term use, the slender rotating frame is also prone to aging and deformation, affecting the rotation experience; and this product has only two rotating frames, and the product in the expanded state does not form a good cylindrical shape, and the appearance is not good. Summary of the Invention

[0004] The utility model aims to provide a dust-removing duster which can be expanded and retracted.

[0005] The purpose of this utility model is achieved in this way:

[0020] 2. The dust collection rack of this utility model is equipped with an extension device on both sides, and an arc-shaped surface is provided on the outer side of the swing member. When the swing member is extended, the arc-shaped surfaces of the swing members abut the dust collection sleeve in the horizontal direction, and the dust collection rack abuts the dust collection sleeve in the longitudinal direction, so that the dust collection sleeve abuts and forms a cylindrical shape. The linkage rod can also provide auxiliary support for the dust collection sleeve. While ensuring stability, the dust duster in the extended state is more beautiful.

[0021] 3. The pusher of the present invention can be connected to the swinging member or linkage; pushing the pusher drives the swinging member or linkage, causing the swinging member to rotate, thereby deploying the extension mechanism. Simply pushing the pusher deploys the extension mechanism, and the user only needs one hand to do so. The user simply grasps the handle and pushes the pusher forward with their thumb, making operation simple. Preferably, the handle is provided with a limit structure to allow the pusher to be held in different positions, thereby maintaining the swinging member at a specified deployment angle.

When the extension device 4 is kept in a folded state, the dust removal sleeve 9 is kept in a retracted state. Figure 7-8As shown, when the extension device 4 is deployed, it pushes the dust collection sleeve 3 to deform and maintain the extended state. The extension device 4 includes a plurality of swinging members 41 rotatably mounted on the dust collection frame. The swinging members 41 are arranged along the length of the dust collection frame. Preferably, there are at least three swinging members 41. The more swinging members, the better the support effect. The specific number is determined by the manufacturer. As shown in the figure, there are six swinging members. The swinging members 41 are connected to each other by a linkage rod 42. The plurality of swinging members 41 connected by the linkage rod 42 can rotate synchronously on the dust collection frame 3. The linkage adopts a hinged linkage. A fixed rod 31 is fixedly mounted in the middle of the dust collection frame 3. A plurality of fixed rod hinge seats 311 are provided in the longitudinal direction of the fixed rod 31. One side of the swinging member 41 is rotatably connected to the fixed rod hinge seat 311. The linkage rod 42 is provided with a linkage rod hinge seat 421. The other side of the swinging member 41 is rotatably connected to the linkage rod hinge seat 421. The dust removal sleeve 9 is an elastic member, which is pressed against the swing member and / or the linkage rod and gives the stretching device a folding force.

[0038] A pusher 2 is slidingly provided on the handle 1, and the pusher 2 can be connected to the swinging member or the linkage rod; when the pusher 2 is pushed, the pusher 2 drives the swinging member or the linkage rod and causes the swinging member to rotate, thereby allowing the stretching device 4 to unfold. There are at least the following connection methods between the pusher 2 and the stretching device 4: Method 1, the connection method between the pusher and the swinging member / linking rod is abutment, and when the pusher is pushed upward, the pusher can push the swinging member / linking rod to move and unfold it. When the pusher is released, the dust cover shrinks and resets and allows the stretching device to remain in a folded state. Method 2, the pusher and the swinging member / linking rod are connected by a transmission rod, one end of the transmission rod is hinged to the pusher, and the other end of the transmission rod is hinged to the swinging member / linking rod. When the pusher moves upward, the stretching device is pushed to unfold, and when the pusher moves downward, the stretching device is pulled to fold. Mode 3: A sliding sleeve is slidingly provided on the connecting rod 411 of the swinging member. The sliding sleeve moves along the connecting rod 411 and is hinged on the pushing member. When the pushing member moves upward, the stretching device is pushed to unfold, and when the pushing member moves downward, the stretching device is pulled to fold.

[0039] The outer side of the swinging member 41 is provided with an arcuate surface. When the swinging member is extended, the arcuate surface abuts the dust collection sleeve 9. When the extension device 4 remains extended, the arcuate surfaces of the multiple swinging members simultaneously support the dust collection sleeve 9. A linkage rod 42 is hinged to the outer side of the arcuate surface and can provide auxiliary support for the dust collection sleeve.
