[0002] As people's living standards improve, cleaning equipment such as vacuum cleaners and mite removers, as members of the household appliance family, have provided great convenience to people's lives. However, due to the presence of low-lying areas in the environment, such as under sofas and beds, that require cleaning, users often need to squat, bend over, or even lie down to reach the extension rod. Currently, few vacuum cleaners on the market have extension rods with bending capabilities, and those that do tend to get stuck in their original position during use. This requires users to unlock the rod again to continue using the product, increasing the cumbersome operation and resulting in a poor user experience. Utility Model Content

[0042] To make the objectives, technical solutions, and advantages of this disclosure clearer, the disclosure will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.
[0043] The terminology used in the embodiments of this disclosure is for the purpose of describing particular embodiments only and is not intended to limit the disclosure.

[0047] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that an article or device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such an article or device. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the article or device that includes said element.
[0048] In home use, cleaning low areas like under sofas and beds often requires squatting, bending over, or even lying down to reach the extension rod. Currently, few cleaning devices on the market offer extension rod bending functionality. Those that do use buttons for bending or resetting, which suffer from inaccurate resetting. This increases the complexity of operation and leads to a poor user experience. Furthermore, the button design requires users to directly overcome spring force, requiring significant effort to unlock and increasing finger fatigue.
[0049] This disclosure provides a connecting component, including: a first joint member; a second joint member connected to the first joint member, wherein the first joint member and the second joint member have three connection states: a locked state, an unlocked state, and an active state. In the locked state, the relative position between the first joint member and the second joint member is locked; in the unlocked state, the second joint member and the first joint member are unlocked and can switch to one of the other two connection states; in the active state, the second joint member can rotate relative to the first joint member within a preset angle range, the preset angle being 0-90 degrees; and a clamp movably disposed on the first joint member, the clamp having a first position, a second position, and a third position relative to the first joint member; wherein, in response to the clamp being in the first position, the first joint member and the second joint member are in the locked state; in response to the clamp being in the second position, the first joint member and the second joint member are in the unlocked state; and in response to the clamp being in the third position, the first joint member and the second joint member are in the active state.
[0050] The connecting assembly provided in this disclosure includes a clamp. When the clamp is in the first position, the clamp teeth engage with the connecting cover to restrict the rotation of the second joint. At this time, the user only needs to switch the clamp from the first position to the second position to release the rotation restriction on the second joint. The connecting assembly provided in this disclosure has a simple overall structure and is easy to operate, meeting the need for bending the cleaning rod in specific situations and improving the user experience.
[0051] In view of the above, the optional embodiments of this disclosure will be described in detail below with reference to the accompanying drawings.
[0052] A first aspect of this disclosure provides a connecting assembly, including: a first joint 100, a second joint 200, a connecting cover 300, and a clamp 400.
[0053] like Figure 1 , Figure 2 As shown, the first joint 100 and the second joint 200 can be hollow cylindrical structures, movably connected by the connecting cover 300. The clamp 400 is sleeved on the outside of the first joint 100 and configured to move in the axial direction of the first joint 100 to change the connection state between the first joint 100 and the second joint 200. The axial direction of the first joint 100 is the height extension direction of the cylindrical structure.
[0054] In some embodiments, the first joint 100 and the second joint 200 have three connection states: a locked state, an unlocked state, and an active state. In the locked state, the first joint 100 and the second joint 200 are locked, that is, the relative position between the first joint 100 and the second joint 200 is locked, and the first joint 100 and the second joint 200 cannot rotate relative to each other, and the axial extension directions of the first joint 100 and the second joint 200 are the same. In the active state, the second joint 200 rotates relative to the first joint 100, and the axial extension directions of the first joint 100 and the second joint 200 are different. In the unlocked state, the second joint 200 can selectively rotate with the first joint 100, that is, the first joint 100 and the second joint 200 can selectively rotate relative to each other or not rotate. The unlocked state is an unconventional state used for state switching, that is, in the unlocked state, it is possible to switch to either the locked state or the active state. Normally, the unlocked state mainly serves as an intermediate state for transitioning from the locked state to the active state.
[0055] In some embodiments, such as Figure 1 , Figure 2 As shown, the clamp 400 can be a sleeve structure, sleeved on the outside of the first joint member 100, and configured to move along the axial direction of the first joint member 100. The clamp 400 has a first position, a second position, and a third position in the axial direction of the first joint member 100, and the clamp 400 can switch between the first position, the second position, and the third position to meet the user's usage needs.
[0056] When the clamp 400 is in the first position, the clamp 400 is engaged with the connecting cover 300. At this time, the second joint 200 cannot rotate relative to the first joint 100. That is, the first joint 100 and the second joint 200 are in a locked state, and the second joint 200 and the first joint 100 have the same axial extension direction.
[0057] When the clamp 400 is in the second position, the clamp 400 moves away from the connecting cover 300 to release the rotation restriction between the first joint 100 and the second joint 200. At this time, the second joint 200 and the first joint 100 are in an unlocked state, that is, the first joint 100 and the second joint 200 are in an unlocked state, and the first joint 100 and the second joint 200 can switch from the unlocked state to the locked state or the active state.
[0058] When the clamp 400 is in the third position, at least a portion of the clamp 400 is inside the connecting cover 300, and the second joint 200 can rotate relative to the first joint 100. That is, the first joint 100 and the second joint 200 are in an active state. At this time, the second joint 200 can rotate relative to the first joint 100 within a preset angle, and the axial extension directions of the second joint 200 and the first joint 100 may be different.
[0059] In some embodiments, such as Figure 2 As shown, the first joint 100 has a connecting outer hole 101, and the second joint 200 has a connecting inner hole 201. The connecting inner hole 201 can be installed inside the connecting outer hole 101, and the connecting inner hole 201 is engaged with the connecting outer hole 101. Specifically, the connecting cover 300 can be disposed through the connecting outer hole 101 and the connecting inner hole 201 to assemble the first joint 100 and the second joint 200. In response to the first joint 100 being assembled with the second joint 200, the center of the connecting outer hole 101 and the connecting inner hole 201 coincides in the axial direction of the connecting cover 300. When the first joint 100 and the second joint 200 are in an unlocked state or an active state, the first joint 100 and the second joint 200 can rotate around the connecting cover 300 in the circumferential direction, so as to make the first joint 100 and the second joint 200 rotate stably.
[0060] In some embodiments, such as Figure 3 As shown, the second joint member 200 further includes a fixing connection hole 202, configured to fix the connecting cover 300 to the second joint member 200. When the connecting cover 300 connects the first joint member 100 and the second joint member 200, at least a portion of the connecting cover 300 is connected to the fixing connection hole 202. When the second joint member 200 rotates, the connecting cover 300 rotates synchronously with the second joint member 200. Figure 4 As shown, the connecting cover 300 has a locking claw 310 on one side facing the axis of the second joint member 200. The locking claw 310 has a certain elasticity and is configured to connect the first joint member 100 and the second joint member 200. Specifically, in the axial direction of the first joint member 100, the locking claw 310 is installed through the connecting outer hole 101 towards the center of the first joint member 100 to engage the first joint member 100 and the second joint member 200. The locking claw 310 is configured to engage with the inner sidewall of the second joint member 200 to ensure a stable connection between the first joint member 100 and the second joint member 200.
[0061] In some embodiments, the connecting cover 300 includes a limiting tooth 320, which is disposed on one side of the connecting cover 300 facing the axis of the second joint member 200. In the axial direction of the second joint member 200, the limiting tooth 320 is directly opposite the fixed connecting hole 202. Figure 4 , Figure 5 As shown, the limiting tooth 320 is a polygonal protrusion structure configured to be fixedly connected to the fixed connection hole 202. In response to the assembly of the first joint member 100 and the second joint member 200, the claw 310 engages with the inner wall of the second joint member 200, and the limiting tooth 320 connects to the fixed connection hole 202. At this time, the connecting cover 300 can rotate synchronously with the second joint member 200.
[0062] In some embodiments, the connecting cover 300 further includes a limiting groove 330, such as Figure 4 As shown, the limiting groove 330 is recessed toward the axial direction of the connecting cover 300 and is configured to engage with a portion of the clamp 400 to restrict the rotation of the second joint 200.
[0063] In some embodiments, such as Figure 6 As shown, the clamp 400 further includes a notch 401 and a clamp insert 410. The notch 401 is located at the bottom end of the side wall of the clamp 400 and is configured to accommodate at least a portion of the connecting cover 300. The clamp insert 410 is located on the inner side wall of the clamp 400 and extends at least partially to the notch 401. The clamp insert 410 is configured to engage with the limiting groove 330 to restrict the rotation of the second joint member 200. When the clamp 400 is in a first position relative to the first joint member 100, the clamp insert 410 engages with the limiting groove 330, and the first joint member 100 and the second joint member 200 are in a locked state.
[0064] In some embodiments, the limiting groove 330 further includes a protrusion 331, which is disposed on the inner sidewall of the limiting groove 330 and configured to abut against the clamp tooth 410 when the clamp 400 is in the first position, so as to assist the clamp tooth 410 in stable engagement with the connecting cover 300.
[0065] In some embodiments, such as Figure 7As shown, the first joint member 100 is further provided with a first sliding groove 130. The first sliding groove 130 is disposed on the outer side wall of the first joint member 100 and communicates with at least a portion of the connecting outer hole 101. At least a portion of the clamping tooth 410 slides inside the first sliding groove 130. The first sliding groove 130 is configured to limit the movement range of the clamp 400 along the axial direction of the first joint member 100, so as to prevent the clamp 400 from dislodging from the first joint member 100 during movement.
[0066] In some embodiments, such as Figure 2 , Figure 7 As shown, the first joint member 100 includes a clamp guide groove 110, which is disposed on the side wall of the first joint member 100. At least a portion of the clamp 400 is movably disposed within the clamp guide groove 110, allowing the clamp 400 to slide along the axial direction of the first joint member 100. The height of the clamp guide groove 110 along the axial direction of the first joint member 100 limits the range of movement of the clamp 400, preventing the clamp 400 from dislodging from the first joint member 100 during movement.
[0067] In some embodiments, such as Figure 8 As shown, the inner wall of the clamp guide groove 110 is provided with an elastic element fixing seat 111. The elastic element fixing seat 111 is used to connect the first elastic element 120. The first elastic element 120 is disposed between the first joint 100 and the clamp 400. One end of the first elastic element 120 abuts against the elastic element fixing seat 111, and the other end of the first elastic element 120 abuts against the clamp 400. Further, when the clamp 400 switches from the first position to the second position, the first elastic element 120 is compressed and contracts. The first elastic element 120 causes the clamp 400 to have a tendency to return from the second position to the first position, which is configured to assist the clamp 400 in returning to its original position.
[0068] In response to the first elastic member 120 extending to its maximum extended length, the clamp 400 is in a first position or a third position; in response to the first elastic member 120 shortening to its minimum compressed length, the clamp 400 is in a second position.
[0069] In some embodiments, the inner wall of the clamp guide groove 110 is further provided with a locking portion 112. The locking portion 112 is disposed at the bottom of the elastic element fixing seat 111 and extends in a direction away from the axis of the first joint member 100. It is configured to at least partially abut against the clamp 400 to assist the clamp 400 in being installed on the first joint member 100, while limiting the movement distance of the clamp 400 on the first joint member 100.
[0070] In some embodiments, such as Figure 4 As shown, the connecting cover 300 includes a second sliding groove 340, which is disposed on at least a portion of the circumferential surface of the connecting cover 300 and has a certain depth in the radial direction of the connecting cover 300. The second sliding groove 340 extends circumferentially along the connecting cover 300, allowing the connecting cover 300 to rotate relative to the clamp 400. The second sliding groove 340 communicates with the limiting groove 330 and is configured to accommodate the clamp insert 410. When the first joint member 100 and the second joint member 200 switch from the unlocked state to the active state, the second joint member 200 rotates synchronously with the connecting cover 300, and the clamp insert 410 slides within the second sliding groove 340, realizing that the first joint member 100 rotates relative to the second joint member 200 within a preset angle.
[0071] In some embodiments, the range of rotation of the second joint 200 is limited by the second sliding groove 340. When the second joint 200 rotates synchronously with the connecting cover 300, the clamping tooth 410 moves within the second sliding groove 340. When the clamping tooth 410 abuts against the inner wall of the second sliding groove 340, the second joint 200 stops rotating. At this time, the angle between the second joint 200 and the first joint 100 is the maximum rotation angle of the second joint 200. The maximum rotation angle is the maximum cleaning angle that the user can make the first joint 100 rotate relative to the second joint 200 during use.
[0072] In some embodiments, there is a preset height difference between the bottom wall of the second sliding groove 340 and the bottom wall of the limiting groove 330. The height difference is equal to the maximum moving distance of the clamping tooth 410, which is the distance the clamp 400 moves when it switches from the first position to the second position. When the clamp 400 is in the first position, the clamping tooth 410 abuts against the side wall of the limiting groove 330 to restrict the rotation of the second joint 200. When the user switches the clamp 400 from the first position to the second position, the clamping tooth 410 disengages from the limiting groove 300, thus releasing the clamp 400 from restricting the rotation of the second joint 200. When the clamp 400 is in the second position, the clamp tooth 410 disengages from the limiting groove 300. There is a rotational gap between the lower edge of the clamp tooth 410 and the bottom wall of the second sliding groove 340. The rotational gap allows part of the clamp tooth 410 to enter the second sliding groove 340. After the clamp tooth 410 enters the second sliding groove 340, the user can remove the external force acting on the clamp 400. At this time, the clamp tooth 410 can slide in the second sliding groove 340. When the second joint 200 is rotated, the second joint 200 will rotate synchronously with the connecting cover 300. When the second joint 200 rotates relative to the first joint 100, the clamp tooth 410 will slide in the second sliding groove 340. The second sliding groove 340 has the function of limiting the rotation angle of the second joint 200.
[0073] In some embodiments, the preset height difference between the bottom wall of the second sliding groove 340 and the bottom wall of the limiting groove 330 is less than the maximum moving distance of the clamping tooth 410. When the user switches the clamp 400 from the first position to the second position, the clamp 400 releases the rotation restriction on the second joint 200. At this time, rotating the second joint 200 will cause the second joint 200 to rotate synchronously with the connecting cover 300. That is, when the second joint 200 rotates relative to the first joint 100, the clamping tooth 410 can fall into the second sliding groove 340 and slide within the second sliding groove 340, thereby achieving a relative bending of the second joint 200 relative to the first joint 100.
[0074] In some embodiments, after the clamp 400 switches from the first position to the second position, when the clamp 400 remains in the second position, the second joint member 200 can rotate relative to the first joint member 100. At this time, as the second joint member 200 rotates, when the clamp insert 410 is located in the second sliding groove 340 and the bottom of the second sliding groove 340 just abuts against the end of the clamp insert 410, the clamp 400 is in the third position. Since the position of the clamp 400 relative to the first joint member 100 does not change during the switching from the second position to the third position, in this embodiment, the second position and the third position of the clamp 400 are the same.
[0075] In some embodiments, such as Figure 2 , Figure 8 As shown, the connecting assembly further includes a support member 500, which has a first connecting hole 501. The first connecting hole 501 is disposed on both sides of the support member 500 and configured to connect with the connecting outer hole 101. The support member 500 has a guide block 510 and a fixing block 520. The guide block 510 is disposed around the first connecting hole 501 and configured to guide the support member 500 to connect with the first joint member 100. The fixing block 520 is located at the center of the inner circumferential surface of the support member 500 and is configured to engage with at least a portion of the first joint member 100 and the second joint member 200, so that the axial position of the second joint member 200 is directly opposite the position of the first joint member 100, ensuring that the connecting inner hole 201 and the connecting outer hole 101 can be accurately aligned. Specifically, the fixing block 520 can be slidably connected with the clamp guide groove 110.
[0076] In some embodiments, such as Figure 8 , Figure 9As shown, the surface of the fixing block 520 is provided with a second connecting hole 502, and the surface of the clamp guide groove 110 is provided with a mounting hole 102. When the support member 500 is installed on the first joint member 100, the fixing block 520 is fixedly connected to the first joint member 100, for example, by screw connection. Specifically, the screw passes through the second connecting hole 502 and the mounting hole 102 to fix the support member 500 to the first joint member 100, and the support member 500 moves synchronously with the first joint member 100. At this time, in response to the clamp 400 being in the second position, the first joint member and the second joint member are in an unlocked state, and the first joint member 100 can rotate relative to the second joint member 200. When the first joint 100 and the second joint 200 rotate relative to each other, the support 500 rotates synchronously with the first joint 100. The connecting cover 300 restricts the position of the first joint 100 or the second joint 200 in its own axial direction. The connecting cover 300 is engaged with the inner wall of the second joint 200. Under the action of external force, the first joint 100 and the second joint 200 can rotate about the axis of the connecting cover 300.
[0077] In some embodiments, such as Figure 10 As shown, the clamp 400 also includes a spring seat 412, which is disposed on the inner side wall of the clamp 400 and configured to install the first elastic member 120, so that the clamp 400 has a tendency to switch from the second position to the first position under the action of the first elastic member 120.
[0078] Specifically, the two ends of the first elastic element 120 abut against the spring seat 412 and the elastic element fixing seat 111, respectively. When the clamp 400 switches from the first position to the second position, the first elastic element 120 is compressed and contracts, causing the clamp 400 to tend to return from the second position to the first or third position, thus assisting the clamp 400 in resetting. The first elastic element 120 not only assists the clamp 400 in resetting but also provides the user with good tactile feedback.
[0079] In some embodiments, the clamp 400 further includes a mounting hook 413, which is disposed on the inner sidewall of the clamp 400, located on the side of the spring seat 412 away from the clamp insert 410, and configured to assist the clamp 400 in connecting with the first joint member 100. Figure 11As shown, when the clamp 400 is installed on the first joint 100, the two ends of the first elastic member 120 abut against the elastic member fixing seat 111 and the spring seat 412, respectively. When the clamp 400 switches from the first position to the second position, the first elastic member 120 is compressed, the spring seat 412 approaches the elastic member fixing seat 111, and the mounting hook 413 moves away from the locking part 112; when the clamp 400 switches from the second position to the first position or the third position, the first elastic member 120 is relaxed, the spring seat 412 moves away from the elastic member fixing seat 111, and the locking part 112 approaches the mounting hook 413 until the locking part 112 abuts against the mounting hook 413.
[0080] In some embodiments, in response to the clamp 400 being in a first position, the clamp tooth 410 engages with the connecting cover 300 to restrict rotation of the second joint 200; in response to the clamp 400 being in a second position, the clamp tooth 410 disengages from the connecting cover 300 to release the rotation restriction on the second joint 200. When the clamp 400 switches between the first and second positions, the first elastic member 120 can cause the clamp 400 to have a tendency to move from the second position to the first position.
[0081] In some embodiments, the clamping tooth 410 further includes a second elastic element 411, such as... Figure 4 , Figure 6 As shown, the portion of the clamp insert 410 that contacts the protrusion 331 may be provided with a second elastic element 411. The second elastic element 411 is disposed on at least one side of the clamp insert 410 and configured to elastically connect with the protrusion 331, thus solving the problem of easy jamming during reset. When the cleaning rod connection assembly is used in a bent state, the first joint 100 and the second joint 200 are reset. During the process of the user applying force to reset the clamp 400 to the first position, the second elastic element 411 and the protrusion 331 are squeezed and undergo elastic deformation, and the clamp insert 410 is re-inserted into the limiting groove 330. At this time, the clamp 400 is in the first position. Thus, it not only meets the need for bending of the cleaning rod under certain circumstances, but also solves the problem of easy jamming during reset. Furthermore, when the clamp 400 is in the first position, the protrusion 331 can prevent the clamp tooth 410 from switching from the first position to the second position without the user applying force, thus preventing the user from accidentally dislodging the clamp tooth 410 from the limiting groove 330.
[0082] In some embodiments, due to the provision of the second elastic member 411, when the clamp 400 switches from the second position to the first position, the second elastic member 411 is elastically engaged with the protrusion 331. The second elastic member 411 has the function of improving the operating feel, allowing the user to more clearly experience the switching of the clamp 400 state and improving the user's user experience.
[0083] In some embodiments, such as Figure 4 , Figure 6 As shown, when the clamp 400 is in the first position, the clamp insert 410 engages with the limiting groove 330. At this time, the second elastic member 411 is pressed against the side wall of the limiting groove 330, so that the clamp insert 410 is accurately engaged with the limiting groove 330. When the clamp 400 is switched from the first position to the second position, the user needs to hold the clamp 400 and move it away from the connecting cover 300 to pull the clamp insert 410 out of the limiting groove 330. When the clamp 400 is switched to the second position, the first joint member 100 and the second joint member 200 can switch from the unlocked state to the locked state or the active state. When the first joint member 100 and the second joint member 200 are in the active state, the clamp 400 is in the third position.
[0084] When the first joint 100 and the second joint 200 are switched to the active state, the connecting component bends. After the cleaning equipment has cleaned the area after the bend, the first joint 100 and the second joint 200 can be switched from the active state to the unlocked state. Furthermore, the clamp 400 is switched from the third position to the second position, and then reset from the second position to the first position. That is, the clamp tooth 410 engages with the limiting groove 330 again to restrict the free rotation of the second joint 200.
[0085] In some embodiments, when the first joint 100 and the second joint 200 are in the unlocked state, the second joint 200 can rotate relative to the first joint 100. When the rotation angle of the second joint 200 relative to the first joint 100 is sufficient to cause the clamping tooth 410 to deviate from the limiting groove 330, the external force applied to the clamp 400 is removed. At this time, under the action of the first elastic member 120, the clamping tooth 410 of the clamp 400 will fall into the second sliding groove 340, that is, the clamp 400 switches from the second position to the third position. In this embodiment, the first position and the third position of the clamp 400 are different positions. In the axial direction of the first joint 100, the first position of the clamp 400 is lower than the third position of the clamp 400. When the clamp 400 is in the third position, the first joint 100 and the second joint 200 are in the active state, and the second joint 200 can rotate relative to the first joint 100.
[0086] In some embodiments, the maximum rotation angle of the second joint 200 can be 90°. In response to the clamp being in the second position, the first joint 100 and the second joint 200 can switch between the unlocked state and the active state. The preset rotation angle between the second joint 200 and the first joint 100 is 0-90 degrees. When the clamp 400 is in the first position, the first joint 100 and the second joint 200 are in the locked state, the clamp tooth 410 is inserted into the limiting groove 330, and the second joint 200 cannot rotate relative to the first joint 100. When the clamp 400 is in the third position, the first joint 100 and the second joint 200 are in the active state, such as... Figure 13 As shown, at this time, the clamping tooth 410 disengages from the limiting groove 330, and the second joint 200 can rotate relative to the first joint 100. The rotation angle between the second joint 200 and the first joint 100 can be 0-85 degrees.
[0087] In other embodiments, such as Figure 14 As shown, the connecting cover 300 is provided with a third sliding groove 350, which has a first end wall 351 and a second end wall 352. A limiting block 353 is provided between the first end wall 351 and the second end wall 352. In response to the clamp 400 being in the first position, the clamp insert 410 engages between the limiting block 353 and the first end wall 351, and the first joint member 100 and the second joint member 200 are in a locked state, that is, the second joint member 200 cannot rotate relative to the first joint member 100.
[0088] In other embodiments, after the clamp 400 switches from the first position to the second position, the clamp 400 moves away from the connecting cover 300 and releases the rotation restriction on the second joint 200. The first joint 100 and the second joint 200 are in an unlocked state, and the first joint 100 and the second joint 200 can switch to a locked state or an active state. When the clamp 400 is in the second position, if the second joint 200 rotates relative to the first joint 100, the user can remove the external force acting on the clamp 400. Under the action of the first elastic member 120, the clamp 400 can move along the height extension direction of the first joint 100 to react on the connecting cover 300. In this state, at least a portion of the clamp insert 410 falls back into the third sliding groove 350 of the connecting cover 300. Specifically, the clamp insert 410 slides between the second end wall 352 and the limiting block 353, and the third sliding groove 350 can restrict the rotation angle of the second joint 200. At this time, the clamp 400 is in the third position, and the first joint 100 and the second joint 200 are in a movable state. For example... Figure 15 As shown, the clamp 400 is in the third position, and the clamp insert 410 can move between the limiting block 353 and the second end wall 352 as the second joint member 200 rotates, so as to realize the rotation of the second joint member 200 relative to the first joint member 100. In this embodiment, the first position and the third position of the clamp 400 relative to the first joint member 100 are the same.
[0089] It should be noted separately that when the clamp 400 is in the first or third position, its position relative to the first joint 100 is approximately the same, but its function differs between the two positions. In the first position, the clamp 400 restricts the switching between the unlocked and active states of the first joint 100 and the second joint 200. In the third position, both joints are in the active state. Simultaneously, due to the limiting block 353, the clamp tooth 410 can move between the limiting block 353 and the second end wall 352 as the second joint 200 rotates, thus allowing the second joint 200 to rotate relative to the first joint 100 while limiting its rotation range. During use, the second joint 200 can rotate within this range, allowing for flexible operation of the cleaning rod or cleaning device using this connecting component.
[0090] A second aspect of this disclosure provides a cleaning rod, comprising: a connecting assembly provided in the first aspect of this disclosure and a cleaning tube 600. The cleaning tube 600 is disposed inside the connecting assembly and configured to draw dust from the operating surface into a dust collection assembly under the action of a power assembly of a cleaning device. The cleaning tube 600 can be a flexible cleaning tube, rotating with the second joint 200 when the second joint 200 rotates relative to the first joint 100. The cleaning rod includes: a first coupling 140, a second coupling 210, and a cleaning tube insertion end 610. The first coupling 140 is disposed at the end of the first joint 100 away from the second joint 200 and configured to connect the first joint 100 to the cleaning rod or other components in the cleaning device. The second coupling 210 is disposed at the end of the second joint 200 away from the first joint 100 and configured to connect the second joint 200 to the cleaning rod or other components in the cleaning device. The cleaning tube connector 610 is located at the end of the cleaning tube 600 furthest from the first joint 100, and is configured to connect the cleaning tube 600 to the second joint 200 or other components in the cleaning equipment. This allows the cleaning tube to collect dirt and dust from the work surface into the dust collection assembly, thus cleaning the work surface.
[0091] A third aspect of this disclosure provides a cleaning device, which may be a vacuum cleaner, a mite remover, or a robotic vacuum cleaner, etc. This cleaning device at least includes a cleaning rod with the aforementioned connecting component. The cleaning device using the connecting component and cleaning rod can be bent at the connecting component according to the user's actual needs to clean narrow crevices or low surfaces. The connecting component has a simple structure and is easy to operate, satisfying the need for bending the cleaning rod in specific situations and solving the problem of the clamp 400 easily getting stuck during use, thus improving the user experience.
[0092] The specific structure, working principle, and beneficial effects of the connecting components, cleaning rods, and cleaning equipment provided in this disclosure can be found in any of the above embodiments, and will not be repeated here.
