Description

Technical Field

[0001] This utility model relates to the field of household appliances technology, and in particular to a rotating component and a duster. Background Technology

[0002] A duster is a common cleaning tool, mainly used to remove dust from the surfaces of furniture, appliances, decorations, etc. A duster typically consists of a handle and a duster head. The handle is easy for the user to hold, while the duster head effectively attracts dust using electrostatic adsorption. The angle between the handle and the duster head is usually adjustable, allowing for cleaning surfaces from different angles.

[0003] Currently, in related technologies, a rotating device is provided between the handle and the dust head of the duster. When the button on the rotating device is pressed, the angle between the handle and the dust head can be adjusted. For example, when the user holds the handle, pressing the button on the rotating device will cause the dust head to rotate relative to the handle.

[0004] However, with the aforementioned rotating device, when the user holds the handle and presses the button to rotate the duster head relative to the handle, the button will rotate along with the duster head, causing friction between the user's hand and the button. This makes it inconvenient for the duster head to rotate and also makes the user's hand uncomfortable, resulting in a poor user experience. Utility Model Content

[0005] This utility model provides a rotating component and a duster to solve the problem that when adjusting the angle between the handle and the duster head using the rotating device in the related technology, the user's hand will rub against the button, which is inconvenient for the duster head to rotate and also makes the user's hand uncomfortable, resulting in a poor user experience.

[0006] This utility model provides a rotating assembly, including: a first connector, a second connector, and two buttons;

[0007] The first connector has two connecting rings with through holes facing each other, and the second connector has a connecting ring disposed between the two connecting rings, with the through holes of the connecting ring facing each other.

[0008] The two buttons are respectively inserted into the through holes of the two connecting rings, and the snap-fit ​​part on each button extends into the through hole of the connecting ring to snap the second mating part on the connecting ring and the first mating part on the opposite connecting ring, so as to restrict the relative rotation between the connecting ring and the two connecting rings.

[0009] Press each of the buttons to move its locking part toward the connecting ring on the opposite side until its locking part disengages from the second mating part, and the connecting ring supports relative rotation with the two connecting rings.

[0010] According to the present invention, a rotating assembly is provided in which a plurality of second mating parts are provided circumferentially inside the through hole of the connecting ring;

[0011] The relative rotation of the connecting ring and the two connecting rings allows any one of the multiple second mating parts to be opposite to the first mating part. The snap-fit ​​part of each button extends into the through hole of the connecting ring and snaps into the opposite first and second mating parts to restrict the relative rotation between the connecting ring and the two connecting rings.

[0012] In this embodiment, a plurality of second mating parts are arranged circumferentially inside the through hole of the connecting ring located between the two connecting rings. Relative rotation of the connecting ring can make any one of the second mating parts face the first mating part on the connecting ring. When different second mating parts face the first mating parts, the connecting ring and the connecting ring will present different angles. When the user rotates to the required angle, the snap-fit ​​part of the button is inserted into the through hole of the connecting ring and snaps into both the corresponding first and second mating parts. This can lock the angle between the connecting ring and the connecting ring, preventing them from continuing to rotate relative to each other, and achieving the effect of locking the connecting ring and the connecting ring at different angles.

[0013] According to the present invention, when the connecting ring rotates relative to the two connecting rings so that any one of the second mating parts is opposite to the first mating part of the opposite connecting ring, the button is driven to move its locking part away from the opposite connecting ring until its locking part re-enters the through hole of the connecting ring and engages with the opposite second mating part, thereby restricting the relative rotation between the connecting ring and the two connecting rings again.

[0014] In this embodiment, after unlocking the relative rotation between the connecting ring and the two connecting rings by pressing the button, the user can adjust the angle by aligning one of the second mating parts with the first mating part of the opposite connecting ring. When rotating to align one of the second mating parts with the first mating part, if the user stops pressing the button, it will drive the button to move its locking part away from the opposite connecting ring until the locking part re-enters the through hole of the connecting ring and engages with the opposite second and first mating parts, preventing them from continuing to rotate relative to each other. This achieves the effect of locking the connecting ring and the connecting ring at different angles.

[0015] According to the present invention, each of the buttons includes a hook portion, which is used to hook onto the opposite connecting ring when the locking portion locks the connecting ring and the opposite connecting ring, so as to restrict the locking portion from moving away from the opposite connecting ring and disengaging from the opposite connecting ring.

[0016] This embodiment provides a specific implementation of the button. Each button is equipped with a hook-and-loop part. When the hook-and-loop part engages with the connecting ring and the opposite connecting ring, the hook-and-loop part can engage with the opposite connecting ring to restrict the hook-and-loop part from moving away from the opposite connecting ring and thus detaching from it. This ensures the locking effect of the hook-and-loop part on the first and second connecting members and improves the stability of the rotating assembly.

[0017] According to the present invention, a rotating assembly is provided, each of the connecting rings is provided with a first limiting part, the button further includes an elastic arm, the hook part is provided on the elastic arm, the elastic arm can undergo elastic deformation when it interferes with the first limiting part during the process of the hook part moving to the connecting ring on the opposite side, so that the hook part passes over the first limiting part, and after passing over, the elastic deformation of the elastic arm recovers, so that the hook part hooks with the first limiting part.

[0018] In this embodiment, the button also includes an elastic arm, which can elastically deform as the hook portion moves toward the connecting ring on the opposite side, facilitating the hook portion to pass over the first limiting portion provided on the connecting ring on the opposite side. After passing over, the elastic deformation of the elastic arm returns to normal, allowing the hook portion to engage with the first limiting portion on the connecting ring on the opposite side. The elastic arm facilitates the hook portion to engage with the first limiting portion, and the first limiting portion facilitates the engagement between the connecting ring and the hook portion. The structure is simple, the installation is firm, and the locking effect between the first connecting member and the second connecting member is effectively guaranteed, improving the stability of the rotating component.

[0019] According to the present invention, a rotating assembly is provided, wherein the snap-fit ​​portion is disposed on the elastic arm, and the snap-fit ​​portion and the hook portion are arranged along the axial direction of the connecting ring.

[0020] In this embodiment, the aforementioned snap-fit ​​portion is disposed on the elastic arm, and the specific snap-fit ​​portion and hook portion are arranged along the axial direction of the connecting ring, resulting in a more regular arrangement structure that facilitates processing and subsequent installation.

[0021] According to the present invention, a rotating component is provided, wherein the locking part is a locking block, the locking block is disposed between the hook part and the pressing part of the button, the locking block is connected to the hook part, the first mating part is a locking groove disposed on the first limiting part, the second mating part is a locking groove, the locking block is locked in the two locking grooves to restrict the relative rotation between the connecting ring and the two connecting rings, and the hook part is hooked to the position on the first limiting part where the locking groove is disposed.

[0022] This embodiment provides a specific implementation of the locking part, the first mating part, and the second mating part. The locking part can be a locking block, the first mating part can be a locking groove provided on the first limiting part, and the second mating part can be a locking groove. When the button auxiliary connecting ring and the connecting ring are locked, the locking block on the button will simultaneously engage in the two locking grooves to restrict the relative rotation between the connecting ring and the connecting ring. In addition, the hook part on the button can also hook into the locking groove on the first limiting part. This double-stabilized restriction of the relative rotation between the connecting ring and the connecting ring results in high operational stability of the rotating component.

[0023] According to the rotating assembly provided by this utility model, each of the connecting rings is further provided with a second limiting part, which is used to limit the movement distance of the button to the opposite connecting ring.

[0024] In this embodiment, each connecting ring is also provided with a second limiting part to limit the movement distance of the button to the opposite connecting ring, so as to prevent the button from being pressed too deeply and affecting the normal operation of the rotating component.

[0025] According to the present invention, a rotating assembly further includes a return spring;

[0026] The reset spring is located between the two buttons. Pressing each button causes its locking part to move toward the connecting ring on the opposite side, which compresses the reset spring and stores force. After the pressing force on the button is removed, the reset spring releases force and drives each button to move in the opposite direction until its locking part locks the connecting ring and the connecting ring on the opposite side again.

[0027] In this embodiment, the rotating assembly also includes a return spring, which is disposed between the two buttons. When each button is pressed, causing its locking part to move towards the connecting ring on the opposite side, the return spring is compressed and stores force. At this time, the connecting ring and the connecting ring can rotate relative to each other. After the pressing force on the button is removed, the return spring will release the force and drive each button to move in the opposite direction until its locking part locks the connecting ring and the connecting ring on the opposite side again. At this time, the connecting ring and the connecting ring are in a locked state and cannot rotate relative to each other. The setting of the return spring ensures the normal operation of the rotating assembly, and the structure is simple and reliable.

[0028] This utility model also provides a duster, comprising:

[0029] handle;

[0030] Dusting;

[0031] Rotating assembly as described in any of the above embodiments;

[0032] The handle and the duster head are connected by the rotating assembly. The first connecting member of the rotating assembly is fixedly disposed at one end of the handle, and the second connecting member of the rotating assembly is fixedly disposed at one end of the duster head.

[0033] In the rotating assembly and duster provided by this utility model, the rotating assembly achieves relative rotation between the first connecting member and the second connecting member by pressing a button. Each button is engaged with a connecting ring and the opposite connecting ring. After pressing the button, the engaging part of the button moves towards the opposite connecting ring and disengages from the connecting ring. Therefore, the rotation of the connecting ring will not cause the button to rotate together. Thus, the relative rotation will not cause friction between the user's hand and the button. On the one hand, it facilitates the rotation of the second connecting member relative to the first connecting member, and on the other hand, it solves the problem of discomfort for the user's hand and improves the user experience.

[0052] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0053] The rotating component and dust removal duster of this utility model are described below with reference to the accompanying drawings.

[0054] According to one aspect, the present invention provides a specific embodiment of a rotating assembly. Figure 1 This is a schematic diagram of the rotating assembly provided by this utility model, as shown below. Figure 1 As shown, the rotating assembly 10 includes: a first connector 101, a second connector 102, and two buttons 103;

[0055] Figure 2 This is a schematic diagram of the structure of the first connecting member in the rotating assembly provided by this utility model. Figure 3 This is a schematic diagram of the structure of the second connecting member in the rotating assembly provided by this utility model, as shown below. Figure 2 and Figure 3 As shown, the first connector 101 is provided with two connecting rings 1011 with through holes A facing each other, and the second connector 102 is provided with a connecting ring 1021. The connecting ring 1021 is disposed between the two connecting rings 1011, and the through hole B of the connecting ring 1021 is opposite to the through hole A of the two connecting rings 1011.

[0056] Figure 4 This is a schematic diagram of the button structure in the rotating assembly provided by this utility model. Figure 5 This is a schematic diagram of the rotating component provided by this utility model when it is not pressed. Figure 6 This is a schematic diagram of the rotating component provided by this utility model when it is pressed, as shown below. Figures 2 to 6 As shown, the two buttons 103 are respectively inserted into the through holes A of the two connecting rings 1011, and the snap-fit ​​portion 1031 on each button 103 extends into the through hole B of the connecting ring 1021 to snap the second mating portion 10211 on the connecting ring 1021 and the first mating portion 10111 on the opposite connecting ring 1011, thereby restricting the relative rotation between the connecting ring 1021 and the two connecting rings 1011;

[0057] Press each of the buttons 103 to move its locking part 1031 toward the connecting ring 1011 on the opposite side until its locking part 1031 disengages from the second mating part 10211, and the connecting ring 1021 supports relative rotation with the two connecting rings 1011.

[0058] In related technologies, for dust dusters, users can press a button on the rotating device to rotate the dust head relative to the handle while holding the handle. However, for the aforementioned rotating device, when the user holds the handle and presses the button to rotate the dust head relative to the handle, the hooks on the button that engage with the two connecting rings (fixed on the handle) are pressed into the middle connecting ring (fixed on the dust head). Therefore, the middle connecting ring supports relative rotation with the two connecting rings, but the button will rotate with the rotation of the middle connecting ring, that is, the button will rotate with the rotation of the dust head. This causes friction between the user's hand and the button, making it inconvenient for the dust head to rotate and uncomfortable for the user's hand, resulting in a poor user experience.

[0059] To address the aforementioned issues, this application provides a rotating component in which the relative rotation between the first connector and the second connector does not cause the button to rotate when the user presses the button.

[0060] Specifically, the rotating assembly 10 includes a first connector 101, a second connector 102, and two buttons 103. The first connector 101 is provided with two connecting rings 1011 with through holes A facing each other. The second connector 102 is provided with a connecting ring 1021, which is disposed between the two connecting rings 1011. The through hole B of the connecting ring 1021 is opposite to the through holes of the two connecting rings 1011, forming an inner cavity that can accommodate the buttons 103.

[0061] When installing and locking the buttons 103, the two buttons 103 are respectively inserted into the through holes A of the two connecting rings 1011, and the snap-fit ​​portion 1031 on each button 103 extends into the through hole B of the connecting ring 1021 to snap the second mating portion 10211 on the connecting ring 1021 and the first mating portion 10111 on the opposite connecting ring 1011, thereby restricting the relative rotation between the connecting ring 1021 and the two connecting rings 1011.

[0062] When unlocking using button 103, each button 103 is pressed to move its locking part 1031 toward the connecting ring 1011 on the opposite side until its locking part 1031 disengages from the second mating part 10211. At this time, the locking part 1031 of each button 103 is only located inside the connecting ring 1011 on the opposite side, which does not affect the rotation of the connecting ring 1021. Therefore, the connecting ring 1021 and the two connecting rings 1011 support relative rotation.

[0063] For button 103, after button 103 is pressed to unlock, the locking part 1031 of button 103 is only located in the connecting ring 1011 on the opposite side, and is relatively independent from the connecting ring 1021. Therefore, the connecting ring 1021 will not drive button 103 to rotate during the rotation of the connecting ring 1011.

[0064] In this embodiment, the rotating assembly 10 achieves relative rotation between the first connecting member 101 and the second connecting member 102 by pressing the button 103. Each button 103 is engaged with a connecting ring 1021 and a connecting ring 1011 on the opposite side. After pressing the button 103, the engaging part 1031 of the button 103 moves towards the connecting ring 1011 on the opposite side and disengages from the connecting ring 1021. Therefore, the rotation of the connecting ring 1021 will not cause the button 103 to rotate together. Thus, the relative rotation will not cause friction between the user's hand and the button 103. This facilitates the rotation of the second connecting member 102 relative to the first connecting member 101 and also solves the problem of discomfort for the user's hand, thus improving the user experience.

[0065] In some embodiments, a specific implementation of the connecting ring 1021 is provided. For example... Figure 3 As shown, a plurality of second mating parts 10211 are provided circumferentially inside the through hole B of the connecting ring 1021;

[0066] Combination Figure 5 and Figure 6 As shown, the relative rotation of the connecting ring 1021 and the two connecting rings 1011 allows any one of the multiple second mating parts 10211 to be opposite to the first mating part 10111. The snap-fit ​​part 1031 of each button 103 extends into the through hole B of the connecting ring 1021 and snaps into the opposite first mating part 10111 and second mating part 10211, thereby restricting the relative rotation between the connecting ring 1021 and the two connecting rings 1011.

[0067] Specifically, a plurality of second mating parts 10211 are arranged circumferentially inside the through hole B of the connecting ring 1021 located between the two connecting rings 1011. Relative rotation of the connecting ring 1021 can make any one of the second mating parts 10211 face the first mating part 10111 on the connecting ring 1011. When different second mating parts 10211 face the first mating part 10111, the connecting ring 1021 and the connecting ring 1011 will present different angles. When the user rotates to the required angle, the snap-fit ​​part 1031 of the button 103 is inserted into the through hole B of the connecting ring 1021 and snaps into both the corresponding first mating part 10111 and the second mating part 10211. This can lock the angle between the connecting ring 1021 and the connecting ring 1011 relative to each other, preventing them from continuing to rotate relative to each other. This achieves the effect of locking the connecting ring 1021 and the connecting ring 1011 at different angles.

[0068] It should be noted that the number of the second mating parts 10211 on the connecting ring 1021 can be set according to the actual situation, and the second mating parts 10211 can be evenly or unevenly arranged in the through hole B along its circumference. This application does not impose any restrictions on either.

[0069] In some other embodiments, there may be only one second mating part 10211.

[0070] In some embodiments, combined with Figures 3 to 6 As shown, when the connecting ring 1021 rotates relative to the two connecting rings 1011, causing any one of the second mating parts 10211 to be opposite to the first mating part 10111 of the opposite connecting ring 1011, the button 103 is driven to move its locking part 1031 away from the opposite connecting ring 1011 until its locking part 1031 re-enters the through hole B of the connecting ring 1021 and engages with the opposite second mating part 10211, thereby restricting the relative rotation between the connecting ring 1021 and the two connecting rings 1011 again.

[0071] Specifically, after unlocking the relative rotation between the connecting ring 1021 and the two connecting rings 1011 by pressing button 103, the user can adjust one of the second mating parts 10211 to face the first mating part 10111 of the opposite connecting ring 1011 to a suitable angle. When rotating to face one of the second mating parts 10211 to face the first mating part 10111, if the user stops pressing button 103, it will drive button 103 to move its locking part 1031 away from the opposite connecting ring 1011 until the locking part 1031 re-enters the through hole B of the connecting ring 1021 and engages with the opposite second mating part 10211 and the first mating part 10111, preventing them from continuing to rotate relative to each other. This achieves the effect of locking the connecting ring 1021 and the connecting ring 1011 at different angles.

[0072] In some embodiments, a specific implementation of button 103 is provided. For example... Figure 4 As shown, each of the buttons 103 includes a hook portion 1032, which is used to hook onto the opposite connecting ring 1011 when the locking portion 1031 locks onto the connecting ring 1021 and the opposite connecting ring 1011, so as to restrict the locking portion 1031 from moving away from the opposite connecting ring 1011 and disengaging from the opposite connecting ring 1011.

[0073] Specifically, the button 103 includes a hook portion 1032. When the latching portion 1031 engages with the connecting ring 1021 and the opposite connecting ring 1011, the hook portion 1032 can engage with the opposite connecting ring 1011 to restrict the latching portion 1031 from moving away from the opposite connecting ring 1011 and disengaging from the opposite connecting ring 1011. This ensures the locking effect of the latching portion 1031 on the first connecting member 101 and the second connecting member 102, and improves the stability of the rotating assembly 10 during operation.

[0074] In some embodiments, combined with Figures 2 to 6 As shown, each of the connecting rings 1011 is provided with a first limiting part 10112. The button 103 also includes an elastic arm 1033. The hook part 1032 is provided on the elastic arm 1033. The elastic arm 1033 can undergo elastic deformation when it interferes with the first limiting part 10112 during the process of the hook part 1032 moving towards the connecting ring 1011 on the opposite side, so that the hook part 1032 passes over the first limiting part 10112. After passing over, the elastic deformation of the elastic arm 1033 returns to normal, so that the hook part 1032 hooks with the first limiting part 10112.

[0075] Specifically, the button 103 also includes an elastic arm 1033, which can elastically deform as the hook portion 1032 on it moves toward the connecting ring 1011 on the opposite side, so that the hook portion 1032 can pass over the first limiting portion 10112 provided on the connecting ring 1011 on the opposite side. After passing over, the elastic deformation of the elastic arm 1033 returns to normal, so that the hook portion 1032 can hook with the first limiting portion 10112 on the connecting ring 1011 on the opposite side. The setting of the elastic arm 1033 facilitates the hook portion 1032 and the first limiting portion 10112 to be hooked and installed. The setting of the first limiting portion 10112 facilitates the hooking of the connecting ring 1011 and the hook portion 1032. The structure is simple, the installation is firm, and the locking effect between the first connecting member 101 and the second connecting member 102 is effectively guaranteed, thereby improving the working stability of the rotating assembly 10.

[0076] In some embodiments, such as Figure 4 As shown, the snap-fit ​​part 1031 is provided on the elastic arm 1033, and the snap-fit ​​part 1031 and the hook part 1032 are arranged along the axial direction of the connecting ring 1021.

[0077] Specifically, the aforementioned snap-fit ​​portion 1031 is disposed on the elastic arm 1033, and the snap-fit ​​portion 1031 and the hook portion 1032 are arranged along the axial direction of the connecting ring 1021, resulting in a more regular arrangement structure that facilitates processing and subsequent installation.

[0078] In some embodiments, a specific implementation of the snap-fit ​​portion 1031, the first mating portion 10111, and the second mating portion 10211 is provided. (In conjunction with...) Figures 2 to 6As shown, the latching part 1031 is a latching block, which is disposed between the hooking part 1032 and the pressing part 1034 of the button 103. The latching block is connected to the hooking part 1032. The first mating part 10111 is a slot provided on the first limiting part 10112, and the second mating part 10211 is a slot. The latching block is latched into the two slots to restrict the relative rotation between the connecting ring 1021 and the two connecting rings 1011. The hooking part 1032 is hooked to the position where the slot is provided on the first limiting part 10112.

[0079] Specifically, the locking part 1031 can be a locking block, the first mating part 10111 can be a locking groove provided on the first limiting part 10112, and the second mating part 10211 can be a locking groove. When the auxiliary connecting ring 1021 of the button 103 is locked with the connecting ring 1011, the locking block on the button 103 will simultaneously engage in the two locking grooves to restrict the relative rotation between the connecting ring 1021 and the connecting ring 1011. In addition, the hooking part 1032 on the button 103 can also hook into the position of the locking groove on the first limiting part 10112. The double stability restricts the relative rotation between the connecting ring 1021 and the connecting ring 1011, and the working stability of the rotating component 10 is high.

[0080] In other embodiments, the snap-fit ​​part 1031 can also be a snap-fit ​​groove, the first mating part 10111 can also be a snap-fit ​​block provided on the first limiting part 10112, and the second mating part 10211 can also be a snap-fit ​​block. When the auxiliary connecting ring 1021 of the button 103 is locked with the connecting ring 1011, the snap-fit ​​groove on the button 103 will simultaneously snap onto the two snap-fit ​​blocks to restrict the relative rotation between the connecting ring 1021 and the connecting ring 1011. In addition, the hook part 1032 on the button 103 can also hook onto the position of the snap-fit ​​block on the first limiting part 10112. The double stability restricts the relative rotation between the connecting ring 1021 and the connecting ring 1011, and the working stability of the rotating component 10 is high.

[0081] In some embodiments, combined with Figures 2 to 6 As shown, each of the connecting rings 1011 is also provided with a second limiting part 10112, which is used to limit the movement distance of the button 103 to the opposite connecting ring 1011.

[0082] Specifically, each connecting ring 1011 is also provided with a second limiting part 10112, which is used to limit the movement distance of the button 103 to the opposite connecting ring 1011, so as to prevent the button 103 from being pressed too deeply and affecting the normal operation of the rotating component 10.

[0083] In some embodiments, the rotating assembly 10 further includes a return spring, which is not shown in the figure above;

[0084] Combination Figure 5 and Figure 6 As shown, the reset spring is disposed between the two buttons 103. Pressing each button 103 causes its locking part 1031 to move toward the connecting ring 1011 on the opposite side, which compresses the reset spring and stores force. After the pressing force on the button 103 is removed, the reset spring releases force and drives each button 103 to move in the opposite direction until its locking part 1031 locks the connecting ring 1021 and the connecting ring 1011 on the opposite side again.

[0085] Specifically, the rotating assembly 10 also includes a return spring, which is disposed between the two buttons 103. When each button 103 is pressed, causing its locking part 1031 to move toward the connecting ring 1011 on the opposite side, the return spring is compressed and stores force. At this time, the connecting ring 1021 and the connecting ring 1011 can rotate relative to each other. After the pressing force on the button 103 is removed, the return spring will release the force and drive each button 103 to move in the opposite direction until its locking part 1031 locks the connecting ring 1021 and the connecting ring 1011 on the opposite side again. At this time, the connecting ring 1021 and the connecting ring 1011 are in a locked state and cannot rotate relative to each other. The setting of the return spring ensures the normal operation of the rotating assembly 10, and the structure is simple and reliable.

[0086] In another aspect, this utility model provides a specific embodiment of a dust removal duster. Figure 7 This is a schematic diagram of the structure of the duster provided by this utility model, as shown below. Figure 7 As shown, the duster includes:

[0087] Handle 20;

[0088] Dusting 30;

[0089] Rotating assembly 10 as described in any of the above embodiments;

[0090] The handle 20 and the duster head 30 are connected by the rotating assembly 10. The first connecting member 101 of the rotating assembly 10 is fixedly disposed at one end of the handle 20, and the second connecting member 102 of the rotating assembly 10 is fixedly disposed at one end of the duster head 30.

[0091] Specifically, the user can hold the handle 20 and use the duster head 30 for cleaning. When it is necessary to adjust the angle between the duster head 30 and the handle 20, the user can press the button 103 on the rotating assembly 10 to adjust the angle between the duster head 30 and the handle 20. For specific implementation details, please refer to the above embodiment of the rotating assembly, which will not be repeated here. When the user presses the button 103 and adjusts the angle between the duster head 30 and the handle 20, the button 103 does not rotate with the rotation of the duster head 30, so there will be no friction between the button and the user's hand. This facilitates the rotation of the second connector relative to the first connector and also solves the problem of discomfort in the user's hand, thus improving the user experience.

[0092] The following examples illustrate the rotating assembly and dust removal duster provided by this utility model.

[0093] The duster includes a handle 20 and a dust head 30, which are rotatably connected by a rotating assembly 10 so that the rotation angle of the dust head 30 is adjustable;

[0094] The rotating assembly 10 includes two connecting rings 1011 located at the end of the handle 20 near the duster head 30, a connecting ring 1021 located at the end of the duster head 30 near the handle 20, two buttons 103, and a return spring (not shown in the figure).

[0095] The connecting ring 1011 and the connecting ring 1021 are both provided with slots, and the two buttons 103 are both provided with a locking block (i.e., a locking part 1031) and a locking hook (i.e., a hooking part 1032). During assembly, the connecting ring 1021 on the duster head 30 is placed between the two connecting rings 1011 on the handle 20, the return spring is placed into the cavity formed by the connecting ring 1021 and the two connecting rings 1011, and then the two buttons 103 are installed into the cavity from both sides of the two connecting rings 1011. During the installation of the buttons 103, the locking hooks and locking blocks on them need to be inserted into the slots on the connecting ring 1011 and the connecting ring 1021 and pressed in until the locking hooks abut against the limiting surface (i.e., the first limiting part 10112) on the connecting ring 1011, and the installation is completed.

[0096] Since the locking block simultaneously engages in the slots on the connecting ring 1011 and the connecting ring 1021, the relative rotation of the connecting ring 1011 and the connecting ring 1021 is restricted, thereby fixing the rotation angle of the duster head 30.

[0097] When it is necessary to adjust the rotation angle of the duster head 30, press both buttons 103 simultaneously to compress the springs. At the same time, the locking blocks on the two buttons 103 move to the other button 103, eventually disengaging from the middle connecting ring 1021. This allows the locking blocks to no longer restrict the connecting ring 1021, enabling the connecting ring 1021 to rotate relative to the two connecting rings 1011. In other words, the duster head 30 can rotate relative to the handle 20. When the duster head 30 is rotated to the appropriate position, release the two buttons 103. Under the action of the springs, the two buttons 103 return to their original positions, causing the locking blocks to engage again with the slots on the connecting ring 1021. This repositions the connecting ring 1021, thus repositioning the duster head 30. During the adjustment of the duster head 30, this not only facilitates the rotation of the second connecting member 102 relative to the first connecting member 101 but also solves the problem of hand discomfort for the user, improving the user experience.

[0098] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
