Description

Technical Field

[0001] The utility model belongs to the technical field of indoor cleaning tools, and particularly relates to a cleaning duster that is easy to use. Background Art

[0002] In the prior art, a duster with a rod body usually has a long rod body, and the end of the long rod body is connected to a soft duster part. The extended rod body helps users easily reach higher or farther positions for cleaning. However, in actual use, due to the long rod body, the user needs to use the handheld end as a fulcrum during operation, and move the duster part to the position that needs to be cleaned by changing the angle of the rod body. In this process, the user's two hands actually form a laborious lever. In order to move a lighter load (i.e., the duster part), the user needs to apply a greater force to the handheld end. This force amplification effect not only increases the burden on the user's hands, but may also cause the cleaning action to become less smooth, and even affect the cleaning effect.

[0003] In addition, the design of this laborious lever also directly affects the cleaning efficiency. On the one hand, since it takes more effort to move the duster, the user may reduce the number of times or strength of cleaning, resulting in incomplete cleaning. On the other hand, due to the effect of the laborious lever, it may be difficult for the user to accurately control the position and angle of the duster, making the cleaning process less precise, and some hard-to-reach corners or gaps may not be effectively cleaned. And if the rod is too long, the duster part may shake during the movement, which also affects the cleaning effect. Utility Model Content

[0026] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] First embodiment, this example discloses a cleaning duster that is easy to use. Refer to Figures 1 - 5 for understanding, which includes a main rod body 100. A hollow cylinder 200 is sleeved on the outer periphery of the main rod body 100. Both ends of the main rod body 100 extend beyond both ends of the hollow cylinder 200. The main rod body 100 and the hollow cylinder 200 are coaxially arranged. One end of the main rod body 100 is an operation end, and the other end is a cleaning end 120. The cleaning end 120 has a duster part 130 for cleaning. The main rod body 100 is provided with a first rotary connection part 140, and the hollow cylinder 200 is provided with a second rotary connection part 210. The first rotary connection part 140 and the second rotary connection part 210 form a rotary connection structure, and the rotary connection structure rotates around the axes of the hollow cylinder 200 and the main rod body 100.

[0028] When in use, the user places one hand on the operation end of the main rod body 100 and the other hand on the hollow cylinder 200. Ensure a firm grip to facilitate stable operation. Before rotating the cleaning duster, the user applies appropriate force to maintain balance and stability, which can avoid losing control during rotation. Subsequently, the user starts to rotate the operation end of the main rod body 100, which can be achieved by the rotational movement of the wrist, and gradually increases the rotation speed. The rotation direction can be one-way or reciprocating, but it is necessary to ensure control and avoid the cleaning duster losing balance due to too fast rotation. By rotating the cleaning duster, the user can effectively clean the target surface or area. According to the cleaning needs, the rotation speed and direction can be adjusted to achieve the best cleaning effect.

[0029] Compared with the traditional non-rotatable feather duster, the structure of this embodiment has greater convenience and efficiency during the cleaning process. Traditional feather dusters are usually fixed and can only be used for cleaning along a fixed direction, which may cause certain difficulties when dealing with different angles or hard-to-reach areas. In contrast, the cleaning duster in this example adopts a rotatable structure, allowing users to easily adjust the direction and angle of the cleaning duster by rotating the operating end to meet different cleaning needs. This rotation function enables the cleaning duster to more flexibly handle different cleaning scenarios, making it easier to clean both the floor and the dust in high places. In addition, users can also adjust the rotation speed and direction according to the cleaning requirements to achieve the best cleaning effect. The specific structure can be further understood in combination with the subsequent embodiments.

[0030] Second Embodiment: Based on the foregoing embodiment, in one example, the operating end is a sheet-like structure extending out of the hollow cylinder 200, and the sheet-like structure is wrapped with a soft material (not shown in the figure). In some examples, the soft material is sponge.

[0031] In this example, for understanding, Figure 1 the duster part 130 is formed by several steel wires extending from the cleaning end 120. The steel wires are in a horn shape as a whole, and a feather duster (not shown in the figure) can be wound around each steel wire. As mentioned above, a feather duster can be wound around each steel wire, and the duster part 130 can be replaced according to different cleaning needs. In addition, in some examples, the steel wire structure of the cleaning end 120 can have barbs, which are used to ensure the firm fixation of the feather duster, avoiding loosening or falling off during the cleaning process, thus ensuring the durability and stability of the cleaning effect.

[0032] Compared with the feather dusters in the prior art, the horn-shaped structure of the cleaning duster in this example makes its edge part present a slender shape. This shape feature enables the edge of the cleaning duster to more easily penetrate into the gaps on the ceiling. Compared with traditional feather dusters that may be difficult to fully cover or enter these narrow gaps due to structural limitations, the horn-shaped cleaning duster can effectively pass through the gaps and sweep out dust and dirt, thus ensuring the cleanliness of the ceiling surface.

[0033] Third Embodiment. Based on the foregoing embodiments, the operating end is connected with a handle 300. In one example, one end of the handle 300 facing the operating end is provided with a connection groove 310. The operating end has a connecting rod 110, and the connecting rod 110 is a rectangular bar extending from the operating end in the direction of the handle 300. The rectangular bar and the connection groove 310 match each other, that is, the connection groove 310 is a rectangular groove body, and the rectangular bar is inserted into the rectangular groove body. The structure formed by the two can effectively limit the rotational freedom of the connecting rod 110 relative to the handle 300. It is not difficult to understand that the handle 300 can have different structures. In one case, it can be as Figure 2 shown.

[0034] The rectangular bar and the rectangular groove are spliced together to form an axial integral structure. This integral structure can not only effectively transmit the rotational force applied by the user on the handle 300, but also stably connect the main rod body 100 and the handle 300. Since the rotational freedom of the connecting rod 110 is restricted by the combination of the rectangular bar and the rectangular groove, the rotational force will be effectively transmitted to the main rod body 100, causing the cleaning duster to rotate. The user can easily control the rotation of the cleaning duster through the handle 300 without losing balance or control due to excessive rotation speed.

[0035] In a specific example, the handle 300 is a bent structure. Specifically, reference can be made to Figure 2 for understanding. In this example, the bent part is an L-shaped structure, and the L-shaped structure includes a first bent part 320 and a second bent part 330, and the two are integrally formed to form the L-shaped structure.

[0036] Combined with the foregoing example, in this example, the first bent part 320 has the connection groove 310, and the connection groove 310 is a rectangular connection groove 310 for matching the rectangular bar. The second bent part 330 has an annular structure 340. The annular structure 340 further includes a plurality of protrusions 341 and grooves 342 matching the physiological structure of the human hand. The height and spacing of the protrusions 341 are such that the fingers and palm can be naturally embedded therein, forming a tight grip feeling to prevent the handle 300 from sliding or rotating during use. The groove 342 part is located between the protrusions 341 to provide a gap between the hand and the handle 300, thereby increasing the flexibility and comfort of the grip. The design of these groove 342 parts allows the fingers to stretch and bend more freely without feeling overly crowded or restricted. At the same time, it also helps with heat dissipation and sweating, reducing the discomfort of the hand caused by long-term use.

[0037] Fourth Embodiment. Based on the foregoing embodiments, in this example, reference is made to Figure 3It is understood that in order to realize the relative rotation of the hollow cylinder 200 and the main rod body 100 to realize the corresponding function, it is necessary to ensure that a rotation connection structure is formed between the main rod body 100 and the hollow cylinder 200. As mentioned in the first embodiment, the main rod body 100 is provided with a first rotation connection part 140, and the hollow cylinder 200 is provided with a second rotation connection part 210. These two connection parts form a rotation connection structure, with the axis of the main rod body 100 and the hollow cylinder 200 as the rotation center. The specific structure is described in this example.

[0038] The first rotating connection portion 140 is a disc body 141 extending from the main rod body 100 . In some examples, the disc body 141 can be replaced by other similar structures, such as a ratchet structure, a friction pair structure, etc.

[0039] exist Figure 3 In the example shown, the disc 141 is provided at the extension of the axis direction of the main rod body 100, the plane of the disc 141 is perpendicular to the axis of the main rod body 100, and the diameter of the disc 141 needs to be larger than the outer diameter of the hollow cylinder 200. As mentioned above, the second rotating connection part 210 should match the first rotating connection part 140. In this example, the second rotating connection part 210 is a hollow disc 211 extending from the hollow cylinder 200, and the inner cavity of the hollow disc 211 matches the outer shape of the disc 141. The second rotating connection part 210 is a hollow disc 211 extending from the hollow cylinder 200, and its inner cavity matches the outer shape of the disc 141 extending from the main rod body 100. Thereby ensuring that the hollow cylinder 200 and the main rod body 100 form a stable rotating connection to achieve the corresponding function. The hollow structure of the hollow disc 211 allows it to be sleeved on the disc 141 of the main rod body 100 to form a relatively tight connection. During the rotation process, the relative position between the main rod body 100 and the hollow cylinder 200 remains relatively stable, and because the shape of the disc body 141 matches the inner cavity of the hollow disc body 211, the stability of the connection is ensured.

[0040] Specifically, the inner cavity of the hollow disc 211 matches the outer shape of the disc 141 extending from the main rod 100. This matching enables the hollow cylinder 200 to rotate relatively around the axis of the main rod 100 during the rotation process, and maintains a stable connection during the rotation without obvious swinging or separation. At the same time, the extension structure of the hollow disc 211 enables it to be completely sleeved on the disc 141 of the main rod 100, forming a continuous rotation connection structure, thereby ensuring stability and reliability during the rotation process.

[0041] The fifth embodiment, based on the above embodiment, the structure in this example can refer to Figure 4It is understood that the first rotary connection part 140 includes a first upper connection part and a first lower connection part; the second rotary connection part 210 includes a second upper connection part and a second lower connection part.

[0042] The first upper connection part is arranged on the cleaning end 120, and the first lower connection part is arranged on the operation end. In this example, reference can be made to Figure 3 To understand the structure of the first upper connection part, the first upper connection part is a disc body 141 extending from the main rod body 100. The disc body 141 extends in a direction perpendicular to the axis of the main rod body 100, and the diameter of the disc body 141 exceeds the outer diameter of the hollow cylinder 200.

[0043] Continue to refer to Figure 4 As shown in the structure, the first lower connection part is a first arc-shaped hollow shell 142 arranged in the groove of the handle 300, and the first arc-shaped hollow shell 142 faces the connecting rod 110.

[0044] Refer to Figure 3 As shown, the second upper connection part is a hollow disc body 211 on the hollow cylinder 200. The inner cavity of the hollow disc body 211 matches the outer shape of the disc body 141, and the hollow disc body 211 is sleeved outside the disc body 141. It is not difficult to understand that the second upper connection part that matches the first upper connection part

[0045] Refer to Figure 4 As shown, the second lower connection part is a second arc-shaped hollow shell 212 extending from one end of the hollow cylinder 200 towards the handle 300. The first arc-shaped hollow shell 142 and the second arc-shaped hollow shell 212 have the same structure and are sleeved inside and outside. It is not difficult to understand that the second lower connection part that matches the first lower connection part.

[0046] As described above, the first rotary connection part 140 includes a first upper connection part and a first lower connection part. The first upper connection part is arranged on the cleaning end 120, while the first lower connection part is arranged on the operation end. This setting enables the connection structure to fully play its role during use. The disc body 141 of the first upper connection part extends along the axis direction of the main rod body 100, and its diameter exceeds the outer diameter of the hollow cylinder 200. Such a design ensures the stability and reliability of the connection. The first lower connection part is a first arc-shaped hollow shell 142 arranged in the groove of the handle 300, facing the connecting rod 110, corresponding to the first upper connection part, and forming the upper rotary connection point.

[0047] The second rotating connection part 210 includes a second upper connection part and a second lower connection part. The second upper connection part is a hollow disk body 211 on the hollow cylinder 200, and its inner cavity matches the outer shape of the disk body 141 on the main rod body 100. Such a match ensures a stable connection during rotation. The hollow disk body 211 is sleeved outside the disk body 141 of the main rod body 100 to form the upper part of the connection. The second lower connection part is a second arc-shaped hollow shell 212 extending from one end of the hollow cylinder 200 towards the handle 300, corresponding to the first lower connection part, and they are sleeved inside and outside to form the lower part of the connection.

[0048] The design of the upper and lower connection parts enables the main rod body 100 and the hollow cylinder 200 to rotate relative to each other and maintain a stable connection during rotation. When in use, the user can control the rotation direction and speed of the cleaning duster by operating the handle 300 and the main rod body 100 to meet the cleaning requirements.

[0049] Sixth embodiment, based on the foregoing embodiments, in this example, the hollow cylinder 200 is a bendable metal tube (not shown in the figure), refer to Figure 5 the shown structure, the main rod body 100 is a segmented rod having a plurality of sub-rod bodies 150, and each sub-rod body 150 is rotationally connected. Specifically, the sub-rod bodies 150 are rotationally connected through a bearing structure, and when full extension is required, it is adjusted by the user, and the corresponding structural adjustment of the bendable metal tube is performed to achieve the bending function.

[0050] Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
