[0038] Embodiment 1:

[0039] As Figures 1-9 shown, the present utility model provides a dust removal duster 1, including: a connecting head 10, a cleaning head 20, a first cleaning piece 30, a second cleaning piece 40, and a locking member 50. The cleaning head 20 is rotatably connected to the connecting head 10. A first connecting portion and a second connecting portion are provided on the cleaning head 20. The first cleaning piece 30 is detachably connected to the first connecting portion; and / or the second cleaning piece 40 is detachably connected to the second connecting portion. The locking member 50 is movably connected to the connecting head 10, and the locking member 50 can selectively move to cooperate with the cleaning head 20 to fix the cleaning head 20 to the connecting head 10, thereby controlling the rotation angle of the cleaning head 20 relative to the connecting head 10.

[0040] In some embodiments, the connecting head 10 includes: a mounting rod and at least one connecting ear. The mounting rod is adapted to be connected to a cleaning rod. One end of each of the at least one connecting ear on the same side is respectively connected to the mounting rod. The at least one connecting ear is respectively rotatably connected to the cleaning head 20. The locking member 50 is movably disposed in the mounting hole 11, and the locking member 50 moves to selectively cooperate with the cleaning head 20, thereby fixing the cleaning head 20 to the connecting ear.

[0041] It is worth mentioning that the number of connecting ears can be 1, 2, 3 or other numbers, which is not limited herein. Preferably, when the number of connecting ears is at least two, the at least two connecting ears are spaced apart from each other. A rotating block 21 is provided on the cleaning head 20, and the rotating block 21 is rotatably disposed between the at least two connecting ears.

[0042] It can be understood that when the locking member 50 does not cooperate with the cleaning head 20, the cleaning head 20 can rotate relative to the connecting ear. When the cleaning head 20 rotates to a certain angle, the locking member 50 moves and cooperates with the cleaning head 20, thereby fixing the cleaning head 20 to the connecting ear, and further fixing the cleaning head 20 to the said angle, realizing the flexible rotation and fixation of the cleaning head 20. The user can use the first cleaning piece 30 and the second cleaning piece 40 at different angles to clean an object, improving the cleaning efficiency.

[0043] For example, after decoration, there is a visible gap between the ceiling board and the purlin board in the room. When using the dust removal duster 1 of the present application, the user can optionally connect the first cleaning piece 30 and / or the second cleaning piece 40 to the cleaning head 20, and rotate the cleaning head 20 relative to the connecting head 10 to a certain angle and fix it. At this time, the shape of the dust removal duster 1 is similar to a "T" or "L" shape (when it is in the "T" shape, both the first cleaning piece 30 and the second cleaning piece 40 are used; when it is in the "L" shape, only the first cleaning piece 30 or the second cleaning piece 40 is used), so as to facilitate the user to use the first cleaning piece 30 and / or the second cleaning piece 40 to clean the visible gap. Of course, for example, the tops of higher household appliances or higher furniture (such as wardrobes and washing machines, etc.) can also be cleaned in the above manner, avoiding the user climbing up and down, and improving the cleaning efficiency of the user.

[0044] At the same time, when cleaning a wall surface or the like, the user can optionally fix the cleaning head 20 to the connecting head 10. When the cleaning head 20 is fixed relative to the connecting head 10, the first cleaning piece 30 and / or the second cleaning piece 40 have good cleaning ability for the wall surface and can be used for cleaning relatively dirty wall surfaces or the like; when the cleaning head 20 is rotatable relative to the connecting head 10, the user can control the rotation angle of the first cleaning piece 30 and / or the second cleaning piece 40 on the wall surface to achieve flexible cleaning of the wall surface, and can improve the cleaning efficiency of the wall surface or the like, and is applicable to the cleaning work of wall surfaces with a certain amount of dust.

[0045] In some embodiments, it may be that the first connecting portion is detachably connected to the first cleaning piece 30, and the second connecting portion is fixedly connected to the second cleaning piece 40; it may also be that the first connecting portion is fixedly connected to the first cleaning piece 30, and the second cleaning portion 31 is detachably connected to the second cleaning piece 40; it may also be that the first connecting portion is detachably connected to the first cleaning piece 30, and the second cleaning portion 31 is detachably connected to the second cleaning piece 40, and there is no limitation here. It should be noted that the above fixed connection can be bonding, fusion bonding, integrally formed, etc., and there is no limitation here.

[0046] It can be understood that for different application scenarios, for example, the cleaning surface areas of different objects to be cleaned are different, and the user can adaptively assemble the dust removal duster 1. In some embodiments, the user can only connect the first cleaning piece 30 or the second cleaning piece 40 to the cleaning head 20. At this time, the user can use the first cleaning piece 30 or the second cleaning piece 40 to clean the object to be cleaned. At this time, the cleaning surface area of the object to be cleaned is small (if the cleaning area of the dust removal duster is too large, it will cause the dust removal duster to be stuck or the cleaning effect on the object to be cleaned to be poor).

[0047] In some other embodiments, the user can connect the first cleaning sheet 30 and the second cleaning sheet 40 to the cleaning head 20 simultaneously. At this time, the user can use the first cleaning sheet 30 and the second cleaning sheet 40 to clean the surface of the object to be cleaned simultaneously. At this time, the area of the surface to be cleaned of the object to be cleaned is large (if the cleaning area of the dust removal duster is too small, the cleaning efficiency of the object to be cleaned will be reduced).

[0048] According to the dust removal duster 1 of the present utility model, by detachably arranging the first cleaning sheet 30 and / or the second cleaning sheet 40 on the cleaning head 20, and the locking member 50 moves to selectively control the rotation angle of the cleaning head 20 relative to the connecting head 10, the dust removal duster 1 has high flexibility. The user can optionally control the cleaning head 20 to rotate to a certain angle or keep the cleaning head 20 rotating relative to the connecting head 10 to clean the object to be cleaned, and the user can optionally use the first cleaning sheet 30 and / or the second cleaning sheet 40 to clean the object to be cleaned, so that the dust removal duster 1 of the present application can be applied to cleaning work in different scenarios and has good cleaning effects in the cleaning work environments of different scenarios.

[0049] Embodiment 2:

[0050] Based on Embodiment 1, in this embodiment, the first cleaning sheet 30 includes a cleaning portion 31 and a third connecting portion connected to each other, and the first connecting portion is detachably connected to the third connecting portion, and the second cleaning sheet 40 is integrally formed with the second connecting portion.

[0051] It can be understood that the second cleaning sheet 40 is integrally formed with the second connecting portion, that is, the second cleaning sheet 40 is integrally formed with the cleaning head 20, which facilitates the production and manufacture of the dust removal duster 1 and improves the production efficiency of the dust removal duster 1. The first cleaning sheet 30 is provided with a third connecting portion, and the first connecting portion is detachably connected to the third connecting portion. Thus, through the above arrangement, the user can selectively disassemble and assemble the first cleaning sheet 30 according to different scenarios, which is convenient for the user to carry out cleaning work. At the same time, when the first cleaning sheet 30 is worn, only the first cleaning sheet 30 can be replaced, avoiding replacing the entire dust removal duster 1 and reducing the use cost of the dust removal duster 1.

[0052] According to some embodiments of the present utility model, one of the first connecting portion and the third connecting portion is configured as a clamping groove 22, and the other of the first connecting portion and the third connecting portion is configured as a clamping block.

[0053] In some embodiments, the first connecting portion is configured as a clamping block. At this time, the cleaning head 20 is provided with a clamping block, and the first cleaning sheet 30 is provided with a clamping groove 22. The clamping block is received in the clamping groove 22 to fix the first cleaning sheet 30 to the cleaning head 20. In other embodiments, the first connecting portion is configured as a clamping groove 22. At this time, the cleaning head 20 is provided with a clamping groove 22, and the first cleaning sheet 30 is provided with a clamping block. The clamping block is received in the clamping groove 22 to fix the first cleaning sheet 30 to the cleaning head 20, and no limitation is made here.

[0054] According to some embodiments of the present invention, the clamping block includes: clamping inserts 321, the clamping inserts 321 are configured as two and are spaced apart from each other. One ends of the two clamping inserts 321 on the same side are respectively adapted to be connected to the cleaning portion 31, and the other ends of the two clamping inserts 321 on the same side are respectively provided with clamping protrusions 322; wherein the two clamping inserts 321 can be selectively deformed towards or away from each other.

[0055] In some embodiments, one end of the cleaning portion 31 is provided with two clamping inserts 321, the two clamping inserts 321 are spaced apart from each other, and the two clamping inserts 321 can be selectively deformed towards or away from each other to facilitate the cooperation of the clamping inserts 321 with the clamping groove 22. At the same time, after the clamping inserts 321 are received in the clamping groove 22, the two clamping protrusions 322 respectively abut against the inner wall of the clamping groove 22 under the action of a restoring force, so that the clamping inserts 321 can be stably received in the clamping groove 22, thereby improving the connection stability between the first cleaning sheet 30 and the cleaning head 20.

[0056] Preferably, the cleaning head 20 is further provided with first clamping holes 23 corresponding to the two clamping protrusions 322 respectively. After the clamping inserts 321 are received in the clamping groove 22, the two clamping inserts 321 move away from each other under the action of a restoring force, so that the clamping protrusions 322 can be received in the first clamping holes 23, and the first clamping holes 23 can limit the freedom degree of the clamping protrusions 322 in the insertion direction, avoiding the clamping inserts 321 from disengaging from the clamping groove 22, and further improving the connection stability between the first cleaning sheet 30 and the cleaning head 20. It should be noted that when it is necessary to disassemble the first cleaning sheet 30, the user can press the two clamping protrusions 322, so that the two clamping inserts 321 are deformed towards each other, and then the clamping inserts 321 can be disengaged from the clamping groove 22. Thus, through the above settings, the disassembly and assembly of the first cleaning sheet 30 and the cleaning head 20 can be facilitated, and the use flexibility of the dust removal duster 1 is improved.

[0057] According to some embodiments of the present utility model, the first cleaning sheet 30 further includes: a limiting convex block, which is disposed between the clamping insert 321 and the cleaning portion 31, and the limiting convex block is adapted to abut against the end of the clamping groove 22. It can be understood that after the clamping insert 321 is received in the clamping groove 22, the limiting convex block can abut against the end of the clamping groove 22, thereby preventing the first cleaning sheet 30 from continuing to move towards the inside of the clamping groove 22, thus ensuring the matching effect between the first cleaning sheet 30 and the cleaning head 20.

[0058] According to some embodiments of the present utility model, a fixing block 14 is provided on the connecting head 10, and a fixing groove 331 is provided on the first cleaning sheet 30. The fixing block 14 can be selectively received in the fixing groove 331 to fix the disassembled first cleaning sheet 30 to the connecting head 10. It can be understood that the cleaning portion 31 is connected to the mounting insert 33, the mounting insert 33 is disposed between the two clamping inserts 321, and a fixing groove 331 adapted to cooperate with the fixing block 14 on the connecting head 10 is provided on the mounting insert 33. After the first cleaning sheet 30 is disassembled, it can be fixed to the connecting head 10 through the cooperation of the fixing groove 331 and the fixing block 14, realizing the stable fixation of the first cleaning sheet 30 in the disassembled state.

[0059] The first cleaning sheet 30 further includes: a connecting strip 34, which is disposed between the clamping insert 321 and the mounting insert 33. One end of the connecting strip 34 is connected to the end of the clamping insert 321, and the other end of the connecting strip 34 is connected to the mounting insert 33 and / or the cleaning portion 31.

[0060] It can be understood that after the two clamping inserts 321 are deformed towards each other, the connecting strip 34 will generate a restoring force. The restoring force of the connecting strip 34 can drive the two clamping inserts 321 to move away from each other, so that the two clamping inserts 321 can be more stably matched with the clamping groove 22, further improving the connection stability between the first cleaning sheet 30 and the cleaning head 20.

[0061] Embodiment Three:

[0062] Based on Embodiment Two, in this embodiment, the connecting head 10 is provided with a mounting hole 11. The locking member 50 includes: a connecting rod 51 and a locking block 52. The connecting rod 51 is movably disposed in the mounting hole 11, and the locking block 52 is disposed on at least a part of the outer peripheral wall of the connecting rod 51. Wherein, the cleaning head 20 is provided with a rotating hole 211, at least a part of the connecting rod 51 is movably disposed in the rotating hole 211, the cleaning head 20 is provided with a plurality of locking grooves 212 spaced apart circumferentially, and the plurality of locking grooves 212 communicate with the rotating hole 211. The connecting rod 51 can be selectively moved axially to receive the locking block 52 in the corresponding locking groove 212.

[0063] In some embodiments, the connecting rod 51 is movably disposed in the mounting hole 11, and at least a part of the outer peripheral wall of the connecting rod 51 is provided with a locking block 52. A rotating block 21 is provided on the cleaning head 20, and a rotating hole 211 is provided on the rotating block 21. The rotating block 21 is rotatably sleeved on at least a part of the outer periphery of the connecting rod 51 through the rotating hole 211. A plurality of rotating grooves are provided on the rotating block 21, and the plurality of rotating grooves communicate with the rotating hole 211 respectively. Thus, when the cleaning head 20 rotates relative to the connecting head 10 by a certain angle, the connecting rod 51 moves and drives the locking block 52 to move towards the locking groove 212, so that the locking block 52 is received in the corresponding locking groove 212, thereby realizing the fixation of the cleaning head 20 relative to the connecting head 10. It should be noted that the extending direction of the locking block 52, the extending direction of the connecting rod 51, the extending direction of the mounting hole 11, and the extending direction of the rotating hole 211 are all parallel.

[0064] Embodiment 4:

[0065] Based on Embodiment 3, the connecting rod 51 of this embodiment includes: a first split part 511 and a second split part 512. The second split part 512 is disposed at one axial end of the first split part 511, and a locking block 52 is provided on the second split part 512; wherein the thickness of the locking block 52 gradually decreases in the direction towards the first split part 511.

[0066] It can be understood that the first split part 511 and the second split part 512 are connected axially. The first split part 511 and the second split part 512 can be fused or welded, etc., which is not limited here. The outer peripheral wall of the second split part 512 is provided with a locking block 52. When the first split part 511 is received in the rotating hole 211, the cleaning head 20 can rotate relative to the connecting head 10. When the second split part 512 is received in the rotating hole 211, the locking block 52 is received in the locking groove 212 to fix the cleaning head 20 and the connecting head 10.

[0067] It should be noted that the locking block 52 has a thickness in the circumferential direction, and the thickness of the locking block 52 gradually decreases in the direction towards the first split part 511, so that a guiding part is formed at the end of the locking block 52 towards the first split part 511, which further facilitates the reception of the locking block 52 in the locking groove 212, makes the cooperation between the locking block 52 and the locking groove 212 easier, facilitates the operation of the dusting brush 1, and improves the user's convenience of use.

[0068] Preferably, the locking block 52 has a center line in the circumferential direction, and both ends of the end of the locking block 52 towards the first split part 511 extend towards the center line. Thus, when the locking block 52 moves towards the locking groove 212, both sides of the end of the locking block 52 towards the first split part 511 can be guided, which further facilitates the cooperation between the locking block 52 and the locking groove 212.

[0069] According to some embodiments of the present utility model, a chute 12 extending axially is provided on the inner peripheral wall of the mounting hole 11. The chute 12 extends away from the connecting rod 51 in the radial direction. The locking block 52 is movably received in the chute 12. Thus, the chute 12 can limit the movement of the locking block 52, making the movement of the locking block 52 more stable. Furthermore, the cooperation between the locking block 52 and the locking groove 212 is more stable, improving the working stability of the dust removing duster 1.

[0070] Embodiment Five:

[0071] Based on Embodiment Four, a limiting block 13 is provided on the inner peripheral wall of the mounting hole 11. A channel extending axially is provided in the connecting rod 51. The connecting rod 51 is further provided with a through hole communicating with the channel. The connecting rod 51 further includes: a deformation strip 513. The two ends of the deformation strip 513 are respectively connected to the two axial ends of the through hole. The deformation strip 513 is provided with a first limiting groove 5131 and a second limiting groove 5132 that are axially spaced apart and adapted to receive the limiting block 13. The projection of the first limiting groove 5131 in the radial direction is located within the locking block 52, and the projection of the second limiting groove 5132 in the radial direction is staggered with the locking block 52.

[0072] It can be understood that a limiting block 13 extending towards the connecting rod 51 in the radial direction is provided on the inner peripheral wall of the mounting hole 11. When the connecting rod 51 moves, the deformation strip 513 can be selectively deformed to allow the limiting block 13 to be received in the first limiting groove 5131 or the second limiting groove 5132, thereby fixing the connecting rod 51 at the first position and the second position. When at the first position, the limiting block 13 is received in the first limiting groove 5131. At this time, the first split part 511 is located in the rotation hole 211, and the cleaning head 20 can rotate relative to the connecting head 10.
