Description

Technical Field

[0001] This utility model relates to the field of cleaning tool technology, specifically to a concealable cleaning head and cleaning tool. Background Technology

[0002] As the main functional component of cleaning tools, the cleaning head is used for cleaning. However, since the cleaning head is used for cleaning, it will inevitably have some dirt after use. When the cleaning head is left outside when not in use, it will affect the appearance and may also cause secondary pollution to the environment.

[0003] How to properly handle the above problems is a common issue faced by cleaning tools. Utility Model Content

[0004] To address at least one of the aforementioned problems, according to one aspect of the present invention, a concealable cleaning head is provided.

[0005] The retractable cleaning head includes a first cleaning head; a first storage member having a first receiving cavity for accommodating the first cleaning head and a first opening for the first cleaning head to extend from the first receiving cavity, the first cleaning head having a first state retracted in the first receiving cavity and a second state located outside the first receiving cavity; a limiting structure disposed on the first storage member for limiting the first cleaning head in the first state; and a locking structure for locking the first cleaning head in the second state relative to the first storage member.

[0006] Therefore, when the first cleaning head is not in use, it can be stored in the first receiving cavity to ensure the aesthetics of the cleaning tool equipped with the retractable cleaning head, while avoiding secondary pollution to the environment. When the first cleaning head is in use, it can be locked onto the first storage member by a locking structure. At this time, the first storage member can be used as the handle of the first cleaning head. Therefore, the lengths of both the first storage member and the first cleaning head can be set to be relatively short, so that the overall length of the first storage member containing the first cleaning head can be relatively short.

[0007] In some embodiments, the first cleaning head is configured to reciprocate between a first state and a second state relative to the first storage component. Therefore, the first cleaning head can be switched between the first and second states by moving relative to the first storage component, making operation convenient.

[0008] In some embodiments, the limiting structure is a limiting block disposed in the first receiving cavity of the first storage component. Therefore, the limiting block can limit the first cleaning head by moving relative to the first storage component until the first cleaning head abuts against the limiting block, making operation convenient.

[0009] In some embodiments, the limiting structure is a first snap-fit ​​structure disposed on at least one of the first cleaning head and the first storage component. Thus, the first snap-fit ​​structure can stably limit the positioning of the first cleaning head and the first storage component without the use of external tools.

[0010] In some embodiments, the locking structure is a second snap-fit ​​structure disposed on at least one of the first cleaning head and the first storage component. Thus, a stable locking of the first cleaning head and the first storage component can be achieved via the second snap-fit ​​structure without the use of external tools.

[0011] In some embodiments, the locking structure is a screw-on mechanism located on at least one of the first cleaning head and the first storage component. This allows for a stable locking of the first cleaning head and the first storage component without the use of external tools.

[0012] In some embodiments, the second snap-fit ​​structure includes a second snap-fit ​​position disposed on one of the first cleaning head and the first storage component, and a second snap-fit ​​block disposed on the other, wherein at least one of the second snap-fit ​​block and the second snap-fit ​​position is capable of elastic deformation.

[0013] In some embodiments, the tightening structure includes a rotary expansion structure disposed on the first cleaning head and located in the first receiving cavity. Thus, by rotating the first cleaning head, the rotary expansion structure can be tightened within the first receiving cavity, achieving locking of the first cleaning head relative to the first receiving component, making operation convenient.

[0014] In some embodiments, the limiting structure includes a first thread on the first cleaning head and a second thread on the inner wall of the first receiving cavity of the first receiving member, adapted to the first thread. Thus, after the first cleaning head and the first receiving member are connected by the first and second threads, not only can they be limited, but they can also support each other.

[0015] In some embodiments, the locking structure includes a third thread on the first cleaning head and a second thread on the inner wall of the first receiving cavity of the first receiving member, adapted to the third thread. Thus, after the first cleaning head and the first receiving member are connected by the third and second threads, they can be locked together. In particular, when the limiting structure includes a first thread on the first cleaning head and a second thread on the inner wall of the first receiving cavity of the first receiving member, adapted to the first thread, the first cleaning head can be stably confined within the first receiving cavity of the first receiving member by the connection of the first and second threads.

[0016] In some embodiments, the retractable cleaning head further includes a second storage member disposed at the end of the first storage member opposite to the first opening, or one end of the second storage member is provided with a fourth thread adapted to the third thread. Thus, the handle of the cleaning head can be extended via the second storage member; and the second storage member can be detachably connected to the first cleaning head via threads.

[0017] In some embodiments, the retractable cleaning head further includes a third storage member. The third storage member has a fourth receiving cavity capable of accommodating the first storage member and a fourth opening communicating with the outside. The fourth opening is located on the same side as the first opening and is configured to allow the first cleaning head to pass through, enabling the third storage member to move relative to the first storage member along the line connecting the first and fourth openings. Thus, the first and third storage members can form a telescopic storage structure, such as a telescopic rod.

[0018] In some embodiments, the end of the first or second storage member facing away from the first opening is provided with a second receiving cavity and a second opening communicating with the outside. A second cleaning head is detachably connected to the second receiving cavity, and at least one of the second cleaning head and the first storage member is provided with a hanging hole. Thus, the first storage member can also store the second cleaning head to increase the cleaning function; moreover, the retractable cleaning head can be suspended through the hanging hole.

[0019] In some embodiments, at least one of the first, second, and third storage components is a tubular structure, and the first storage component and at least one of the second and third storage components constitute a retractable rod. This allows for the extension of the handle of the first cleaning head while maintaining the compactness of the retractable cleaning head structure.

[0020] In some embodiments, the second cleaning head is provided with a third receiving cavity, which houses the third cleaning head. Thus, by housing the third cleaning head within the second cleaning head, the number of cleaning heads can be increased while maintaining structural compactness.

[0021] In some implementations, one of the first cleaning head and the second cleaning head is a duster, and the other is a brush. Thus, dust can be removed by the duster, and cleaning can be performed by the brush.

[0022] According to another aspect of this utility model, a cleaning tool is provided, which includes the aforementioned retractable cleaning head. Thus, when the cleaning head is not in use, its aesthetic appeal can be achieved by concealing it, while maintaining environmental cleanliness and preventing the cleaning head from causing further environmental pollution.

[0054] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0055] Figures 1 to 9 The concealable cleaning head according to a first embodiment of the present invention is shown schematically.

[0056] like Figure 3 and Figure 9 As shown, the retractable cleaning head includes a first cleaning head 20, a first storage component 30, a limiting block 331, and a second snap-fit ​​structure 341. Figure 3 and Figure 9 As shown, the first receiving member 30 is integrally formed or machined with a first receiving cavity 31 and a first opening 32 communicating the first receiving cavity 31 with the outside. The first receiving cavity 31 and the first opening 32 are configured to allow the first cleaning head 20 to extend from the first receiving cavity 31 through the first opening 32. The first cleaning head 20 has a first state in which it is received in the first receiving cavity 31 (e.g., Figure 1 , Figure 3 (as shown) and the second state located outside the first receiving cavity 31 (as shown) Figure 8 and Figure 9 As shown). Figure 3 , Figure 5 and Figure 9 As shown, the limiting block 331 is integrally formed, processed, or connected to the first receiving member 30 and is located in the first receiving cavity 31, for abutting against the first cleaning head 20 when the first cleaning head 20 is located in the first receiving cavity 31. Figure 8 and Figure 9 As shown, the second snap-fit ​​structure 341 can lock the first cleaning head 20 in the second state relative to the first storage member 30.

[0057] Therefore, when the first cleaning head 20 is not in use, it can be stored in the first receiving cavity 31 to ensure the aesthetics of the cleaning tool with the retractable cleaning head and to prevent the first cleaning head 20 from causing secondary pollution to the environment. At this time, the limiting block 331 can ensure that the first cleaning head 20 is stored in the limit position in the first receiving cavity 31. When the first cleaning head 20 is in use, it can be locked onto the first storage member 30 by the second snap-fit ​​structure 341. At this time, the first storage member 30 can be used as the handle of the first cleaning head 20. Therefore, the lengths of the first storage member 30 and the first cleaning head 20 can be set to be relatively short so that the overall length of the first storage member 30 containing the first cleaning head 20 can be relatively short.

[0058] Some embodiments of the second snap-fit ​​structure 341, such as Figure 3 , Figure 5 , Figure 8 and Figure 9 As shown, the second latching structure 341 includes a second latching block 3411a connected to the first rod 21 of the first cleaning head 20; and a second latching position 3411b adapted to the second latching block 3411a; the side of the second latching block 3411a facing away from the first cleaning head 20 is integrally formed or machined with a first step 3411a-1; the end of the first opening 32 of the first receiving member 30 constitutes the second latching position 3411b of one embodiment of this application. Preferably, the second latching block 3411a is elastically deformable. Preferably, at least two sets of second latching blocks 3411a are provided to form a first through groove 3411a-3 between adjacent second latching blocks 3411a so that the second latching blocks 3411a can deform. Preferably, the side of the second latching block 3411a facing the first cleaning head 20 is integrally formed or machined with a first guide 3411a-2, for example, with a rounded corner or chamfer.

[0059] In some preferred embodiments, the first cleaning head 20 is configured to reciprocate between a first state and a second state relative to the first receiving member 30. Thus, by moving the first cleaning head 20 relative to the first receiving member 30, the first cleaning head 20 in its first state (e.g., ...) can be achieved. Figure 1 and Figure 3 (as shown) and the second state (as shown) Figure 8 and Figure 9 Switching between (as shown) is convenient.

[0060] In some preferred embodiments, such as Figure 3 , Figure 8 and Figure 9As shown, the retractable cleaning head also includes a third storage member 50. The third storage member 50 is provided with a fourth receiving cavity 51 that can accommodate the first storage member 30 and a fourth opening 52 that connects the fourth receiving cavity 51 to the outside. The fourth opening 52 is located on the same side as the first opening 32 and is configured to allow the first cleaning head 20 to pass through, so that the third storage member 50 can move relative to the first storage member 30 along the line connecting the first opening 32 and the fourth opening 52. Thus, the first storage member 30 and the third storage member 50 can form a telescopic storage structure, such as a telescopic rod.

[0061] In some preferred embodiments, such as Figures 1 to 4 , Figure 8 and Figure 9 As shown, the end of the first storage member 30 opposite to the first opening 32 is integrally formed or machined with a second receiving cavity 35 and a second opening 36 communicating the second receiving cavity 35 with the outside. A second cleaning head 41 is detachably connected to the second receiving cavity 35. At least one of the second cleaning head 41 and the first storage member 30 is provided with a hanging hole 411. Thus, the first storage member 30 can also store the second cleaning head 41 to increase the cleaning function; moreover, the retractable cleaning head can be suspended through the hanging hole 411. The second cleaning head 41 is detachably connected to the second receiving cavity 35 by means that the second receiving cavity 35 of the first storage member 30 is integrally formed or machined with a fourth slot 37 that can engage with the second cleaning head 41.

[0062] In some preferred embodiments, such as Figure 3 , Figure 4 , Figure 7 and Figure 9 As shown, a third receiving cavity 412 is integrally formed or machined on the second cleaning head 41, and the third cleaning head 42 is accommodated in the third receiving cavity 412. Thus, by accommodating the third cleaning head 42 in the second cleaning head 41, the number of cleaning heads can be increased while maintaining the compactness of the structure.

[0063] In some embodiments, such as Figure 3 , Figure 4 , Figure 7 and Figure 9 As shown, one of the first cleaning head 20 and the second cleaning head 41 is a duster, and the other is a brush. Thus, dust can be removed by the duster, and cleaning can be done by the brush.

[0064] In some embodiments, such as Figure 3 , Figure 4 , Figure 7 and Figure 9 As shown, the third cleaning head 42 is a dust collection shovel, used to collect dirt swept out by the first cleaning head 20 and / or the second cleaning head 41.

[0065] In some embodiments, at least one of the first storage member 30 and the third storage member 50 is a tubular structure, and the first storage member 30 and the third storage member 50 constitute a retractable rod. Thus, while extending the handle of the first cleaning head 20, the compactness of the retractable cleaning head structure can be maintained.

[0066] The limiting block 331 constitutes a limiting structure 33 in one embodiment of this application, which can limit the first cleaning head 20 in the first state.

[0067] The second snap-fit ​​structure 341 constitutes a locking structure 34 in one embodiment of this application, which is capable of locking the first cleaning head 20 in the second state relative to the first storage member 30.

[0068] Figures 10 to 17 The diagram schematically illustrates a retractable cleaning head according to a second embodiment of the present invention. The main differences between the retractable cleaning head of this embodiment and the retractable cleaning head of the first embodiment are: the limiting structure 33 is different and / or the locking structure 34 is different.

[0069] like Figure 11 and Figure 12 As shown, in some embodiments, the limiting structure 33 is a first snap-fit ​​structure 332 disposed on at least one of the first cleaning head 20 and the first storage member 30. Thus, the first snap-fit ​​structure 332 can stably limit the first cleaning head 20 and the first storage member 30 without the use of external tools.

[0070] As one embodiment of the first snap-fit ​​structure 332, such as Figure 11 and Figure 12 As shown, the first snap-fit ​​structure 332 includes a first slot 3322 integrally formed or processed on the first rod 21 of the first cleaning head 20; and a first block 3321 integrally formed, processed or connected to the first storage member 30, wherein the first block 3321 is adapted to the first slot 3322.

[0071] The second snap-fit ​​structure 341 constitutes a locking structure 34 in one embodiment of this application, which is capable of locking the first cleaning head 20 in the second state relative to the first storage member 30.

[0072] As one embodiment of the second snap-fit ​​structure 341, such as Figure 16 and Figure 17 As shown, the second snap-fit ​​structure 341 includes a first slot 3322 integrally formed or processed on the first rod 21 of the first cleaning head 20; and a third block 3412a integrally formed or processed on the first storage member 30, the third block 3412a being adapted to the first slot 3322.

[0073] Figures 18 to 23 The diagram schematically illustrates a retractable cleaning head according to a third embodiment of the present invention. The main differences between the retractable cleaning head of this embodiment and the retractable cleaning head of the first embodiment are: the limiting structure 33 is different and / or the locking structure 34 is different.

[0074] In some preferred embodiments, such as Figure 19 and Figure 20 As shown, the limiting structure 33 includes a first thread 333 disposed on the first rod 21 of the first cleaning head 20, and a second thread 334 disposed on the inner wall of the first receiving cavity 31 of the first receiving member 30, which is adapted to the first thread 333. Thus, after the first cleaning head 20 and the first receiving member 30 are connected by the first thread 333 and the second thread 334, not only can they be limited, but they can also support each other.

[0075] In some preferred embodiments, such as Figures 21 to 23 As shown, the locking structure 34 includes a third thread 335 disposed on the first cleaning head 20 and a second thread 334 disposed on the inner wall of the first receiving cavity 31 of the first receiving member 30 and adapted to the third thread 335. Thus, after the first cleaning head 20 and the first receiving member 30 are connected by the third thread 335 and the second thread 334, they can be locked together, allowing the first receiving member 30 to act as a handle for the first cleaning head 20; in particular, when the limiting structure 33 includes the first thread 333 disposed on the first cleaning head 20 and the second thread 334 disposed on the inner wall of the first receiving cavity 31 of the first receiving member 30 and adapted to the first thread 333, the first cleaning head 20 can be stably limited in the first receiving cavity 31 of the first receiving member 30 by the connection of the first thread 333 and the second thread 334. Preferably, the third thread 335 is disposed on the side of the first thread 333 away from the first cleaning head 20, and the second thread 334 is disposed on the end of the first storage member 30 near the first opening 32, so that when the first cleaning head 20 is connected to the second thread 334 of the first storage member 30 through the third thread 335 thereon, the first storage member 30 can act as a handle for the first cleaning head 20.

[0076] In some preferred embodiments, such as Figures 18 to 21As shown, the retractable cleaning head also includes a second storage member 35a. The second storage member 35a is disposed at the end of the first storage member 30 opposite to the first opening 32, or one end of the second storage member 35a is provided with a fourth thread 35a-1 adapted to the third thread 335. The fourth thread 35a-1 is disposed in the second storage member 35a, which has a third opening 35a-2 for the third thread 335 to enter and exit. Thus, the handle of the cleaning head can be extended by the second storage member 35a; and the second storage member 35a and the first cleaning head 20 can be detachably connected by threads.

[0077] The difference between the retractable cleaning head of this embodiment and the retractable cleaning head of the first embodiment is that: Figure 19 As shown, a second receiving cavity 35 containing a second cleaning head 41 and a second opening 36 are disposed on a second storage member 35a, with the second opening 36 disposed at one end of the second storage member 35a opposite to the third opening 35a-2.

[0078] In some embodiments, the second thread 334 and the third thread 335 constitute a locking structure 34 of one embodiment of this application.

[0079] In some embodiments, at least one of the first storage member 30, the second storage member 35a, and the third storage member 50 is a tubular structure, and at least one of the first storage member 30 and the second storage member 35a and the third storage member 50 constitutes a retractable rod. Thus, while extending the handle of the first cleaning head 20, the compactness of the retractable cleaning head structure can be maintained.

[0080] Figures 24 to 27 The diagram schematically illustrates a retractable cleaning head according to a fourth embodiment of the present invention. The main difference between the retractable cleaning head of this embodiment and the retractable cleaning head of the first embodiment lies in the different locking structure 34.

[0081] In some preferred embodiments, such as Figures 24 to 27 As shown, the locking structure 34 is a tightening structure 342 disposed on at least one of the first cleaning head 20 and the first storage member 30. Therefore, the first cleaning head 20 and the first storage member 30 can be stably locked together without the use of external tools by tightening the structure 342. In some embodiments, the tightening structure 342 includes a rotational expansion structure disposed on the first rod 21 of the first cleaning head 20 and located in the first receiving cavity 31. Thus, by rotating the first cleaning head 20, the rotational expansion structure can be tightened within the first receiving cavity 31, thereby locking the first cleaning head 20 relative to the first storage member 30, making operation convenient.

[0082] As one embodiment of the rotational expansion structure, such as Figure 27As shown, the rotary expansion structure includes a deformable open ring 3421 with a second through groove 3421a and capable of elastic deformation, sleeved on the first rod 21. A fifth locking block 3422 is integrally formed, machined, or connected to the first rod 21. A fifth locking groove 3421b, which can be adapted to the fifth locking block 3422, is also integrally formed or machined on the inner diameter of the deformable open ring 3421 away from the second through groove 3421a. The first rod 21 is configured to drive one side of the deformable open ring 3421 located on either side of the second through groove 3421a to move relative to the other side, and to enable the fifth locking block 3422 to engage in the fifth locking groove 3421b (so that the deformable open ring 3421...). 21 expands and deforms in the first receiving cavity 31 so that the first rod 21 can no longer rotate automatically relative to the first storage member 30, thereby realizing the function of locking the first cleaning head 20 relative to the first storage member 30); the first rod 21 is also configured to drive one side of the deformable opening ring 3421 located on both sides of the second through groove 3421a to move relative to the other side, and to enable the fifth locking block 3422 to move out of the fifth locking groove 3421b (so that the deformable opening ring 3421 contracts and deforms in the first receiving cavity 31, so that the first rod 21 can rotate automatically again relative to the first storage member 30, thereby realizing the function of unlocking the first cleaning head 20 relative to the first storage member 30).

[0083] According to another aspect of this utility model, a cleaning tool is provided, which includes the aforementioned retractable cleaning head. Thus, when the cleaning head is not in use, the tool's aesthetics can be achieved by concealing it, while maintaining environmental cleanliness and preventing the cleaning head from causing further environmental pollution. Furthermore, other cleaning heads can be connected to storage components (first storage component 30, second storage component 35a, or third storage component 50 to act as operating levers).

[0084] In this invention, the connection or installation is a fixed connection unless otherwise specified.
