[0020] The present invention is further described below through specific implementation methods.
[0021] The dust duster structure includes a dust removal rod 12 and a cleaning component 11. Figure 4 This is one of the specific implementation cases of the dust removal rod. The dust removal rod includes an inserting piece 121 and a hand-held portion 122. The cleaning component 11 is detachably sleeved on the inserting piece 121. Figure 1 This is one of the specific implementation cases in which the cleaning component is sleeved on the inserting piece 121 .
[0022] The direction in which the hand-held portion 122 of the dust removal rod 12 extends toward the inserting portion 121 is defined as the length direction Y. Figure 3 The inserting piece portion 121 includes a left inserting piece 1211 and a right inserting piece 1212. The left and right inserting pieces are symmetrical about the central axis Y1. The left and right inserting pieces 1211 and 1212 are both provided with a serrated edge 1213 on one side. The number of serrations can be multiple, preferably 2-6. The serration tips of the serrated edges are rounded. The rounded design can reduce the obstruction of relative movement when contacting other objects. The left and right inserting pieces each have a first end 1211a, 1212a away from the hand-held portion and a second end 1211b, 1212a close to the hand-held portion. b. The left and right inserts both have first ends 1211a and 1212a away from the handheld portion, which are also rounded. There is a first spacing X1 between the first ends 1211a and 1212a of the left and right inserts away from the handheld portion, and there is a second spacing X2 between the second ends 1211b and 1212b of the left and right inserts away from the handheld portion. The first spacing X1 is greater than the second spacing X2. Preferably, the first spacing X1 is 1.5-5 times the second spacing X2. When in use, the first spacing X1 can be temporarily reduced under the action of external force to meet the needs. When the external force is removed, the first spacing X1 returns to its original size. Figure 6 This is a specific implementation example of a state in which the first spacing X1 is reduced. The rounded corner design and the left and right insert angle design can make it easier for the insert to be inserted into the cleaning component. Figure 7 is the state when the insert piece is completely inserted into the cleaning component under the action of external force, and the state after the external force is removed can be Figure 1 Presentation.
[0023] The cleaning component 11 includes a first base cloth 112, a second base cloth 113 and a fiber bundle 111. The fiber bundle 111 is fixed to a first surface of the first base cloth 112 through a fixing portion 11a. The second base cloth 113 is fixed to a second surface of the first base cloth 112. A joining portion 11b and a non-joining portion are provided between the first base cloth 112 and the second base cloth 113. The non-joining region forms an accommodating space for accommodating the insert portion 121. Figure 1 , Figure 2 , Figure 5 , Figure 6 This is one of the specific implementation cases of the joint 11b. The joint 11b can also be a continuous joint or include a partially scattered joint and a partially continuous joint. The connecting edge of the first base cloth 112 and the second base cloth 113 has an opening 117, and the insert portion 121 can be inserted into the cleaning component from the opening. The base cloth at the opening can be provided with embossing or other significant features to improve recognition.
[0024] like Figure 2 When the insert portion 121 and the cleaning component 11 are in a combined state, that is, the insert portion 121 is accommodated in the accommodating space of the cleaning component 11, the serrations of the serrated side edge 1213 of the insert portion 121 have two first edges 1213a and second edges 1213b with different orientations. The area of the cleaning component 11 near the second edge 1213b of the second edge 1213b is an adjacent area of the second edge 1213b, and a joint portion 11b1 of the cleaning component 11 is provided in the adjacent area. The joint portion 11b1 has an obstructive effect on the movement of the insert portion 121 toward the hand-held portion, thereby enhancing the socketing stability between the insert portion and the cleaning component, making it difficult for the cleaning component of the dust duster to detach during cleaning, thereby improving the efficiency of the cleaning process and the user's satisfaction.
[0025] The above are only a few specific implementation methods of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
