[0044] In one feasible implementation, the cleaning device is a mop, and the cleaning unit is the mop head of the mop.

[0045] The technical solution of this invention has the following advantages:

[0046] 1. The cleaning device provided by the present invention divides the rod into a first rod body and a second rod body, and the opening and closing component into a first connecting part and a second connecting part, which are respectively disposed in the first rod body and the second rod body. The first connecting part and the second connecting part only connect to form the opening and closing component when the first rod body and the second rod body are connected. On the one hand, this achieves a solution where the first rod body and the second rod body can be transported separately, and the first connecting part and the second connecting part can connect to form an opening and closing component that drives the switching of the state of the load-bearing base during use. This avoids the situation where the rod body cannot be disassembled for transport due to the need for an opening and closing component, and also makes it easy to install the first rod body and the second rod body during use. On the other hand, the connection of the first connecting part and the second connecting part achieves dual limiting of the first rod body and the second rod body, improving the tightness of the connection between the first rod body and the second rod body, and ensuring the stability of the cleaning device during use.

[0047] 2. In the cleaning device provided by the present invention, the transmission component is flexibly configured.

[0048] This design allows the transmission component to be tensioned and control the state switching of the bearing base when an external force is applied to drive the two parts to move along the axial direction of the rod after the second and first connecting parts are connected. It also allows the transmission component to bend when the bearing base needs to be rotated to a stacked state for storage, without the need for disassembly.

[0049] 3. The cleaning device provided by the present invention has a plurality of opening and closing limiting cavities arranged along the axial direction of the rod in the opening and closing main body. Each opening and closing limiting cavity is provided with an opening and closing through hole. The end of the transmission member passes through the opening and closing through hole and is engaged and limited by an opening and closing limiting block provided at the end with one of the plurality of opening and closing limiting cavities.

[0050] By setting several opening and closing limiting cavities, the axial length of the transmission component between the opening and closing body and the bearing base can be adjusted by selecting the opening and closing limiting cavity that is limited by the opening and closing limiting block, thereby achieving pre-tightening of the transmission component and ensuring smooth transmission. Furthermore, the opening and closing body and the transmission component can be structurally disassembled, facilitating subsequent component replacement and maintenance, and also providing a basis for the detachable connection between the first rod and the cleaning unit.

[0051] 4. In the cleaning device provided by the present invention, the second limiting end of the second connecting part is provided with a barb, and the limiting mating part of the first connecting part is provided with an elastic gripper, or the second limiting end is provided with an elastic gripper, and the limiting mating part is provided with a barb.

[0052] The second limiting end and the limiting mating part are designed to detachably engage and limit each other in the form of elastic claws and barbs. After engagement, when the stress limit of the engagement limit is not exceeded, the first connecting part receives an external force, which drives the second connecting part to move along the axial direction of the rod, thereby controlling the opening and closing of the clamping cavity. Furthermore, since the elastic claws can elastically deform under external force, when the axial pulling force on the first connecting part is further increased and exceeds the stress limit of the engagement limit of the second limiting end and the limiting mating part, the two parts can be disengaged, achieving disassembly. In summary, by applying external force to the first connecting part, the first connecting part can be driven to move. Alternatively, by adjusting the magnitude of the external force and the stroke of the first connecting part, the connection and disconnection of the two connecting parts can be controlled, simplifying the operation and improving the user experience.

Detailed Implementation

[0076] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0077] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0078] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0079] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0080] like Figures 1-21 This embodiment provides a cleaning device, specifically a mop, but it can also be a long brush or a window cleaner, etc., including: a pole and a cleaning unit.

[0081] The cleaning unit includes a decontamination structure and a support base 7. The support base 7 has a working state for clamping the decontamination structure and a replacement state for easy removal of the decontamination structure. The rod may include a first rod body 1 and a second rod body, which are detachably connected. The first rod body 1 may have a first connecting portion, and the second rod body may have a second connecting portion 4. Both the first rod body 1 and the first connecting portion are connected to the support base 7. When the first rod body 1 and the second rod body are connected, the first connecting portion and the second connecting portion 4 are connected to form an opening and closing member, used to control the support base 7 to switch from the working state to the replacement state when driven to move.

[0082] For example, the rod includes a first rod body 1 and a second rod body, which can be hollow cylindrical, coaxially arranged, and detachably connected at their ends. The first rod body 1 has a built-in first connecting portion, and the second rod body has a built-in second connecting portion 4. When the first rod body 1 and the second rod body are connected, the first connecting portion and the second connecting portion 4 can connect to form an opening / closing member. This opening / closing member is used to control the load-bearing base 7 to switch from a working state to a replacement state when driven to move. Optionally, the second connecting portion 4 can be driven to move along the axial direction of the rod, causing the first connecting portion to move in the same direction. The first connecting portion is connected to the load-bearing base 7, so when the first connecting portion moves, the load-bearing base 7 can be controlled to switch from a working state to a replacement state. In this embodiment, the driving force of the second connecting portion 4 can be the user's manual driving force, or the driving force of an added motor or push rod. As a variable implementation, the first rod body 1 and the load-bearing base 7 can also be detachably connected.

[0083] Optionally, the cleaning structure is a cleaning cloth or wiping cloth, etc. When the supporting base 7 is in the working state, the cleaning cloth or wiping cloth is clamped on the supporting base 7; when the supporting base 7 is in the replacement state, the user can remove the used dirty cleaning cloth or wiping cloth from the supporting base 7 to replace it with a new clean cleaning cloth or wiping cloth.

[0084] It should be noted that when the opening / closing member formed by the connection of the first connecting part and the second connecting part 4 is driven to move in the opposite direction, it can also control the load-bearing base 7 to switch from the replacement state to the working state. Specifically, when the second connecting part 4 is driven to move forward along the axial direction of the rod, it can drive the first connecting part to move forward in the same direction. Since the first connecting part is connected to the load-bearing base 7, it can control the load-bearing base 7 to switch from the working state to the replacement state. When the second connecting part 4 is driven to move in the opposite direction along the axial direction of the rod, it can drive the first connecting part to move in the same direction. At this time, the movement of the first connecting part can control the load-bearing base 7 to switch from the replacement state to the working state.

[0085] The supporting base 7 can be plate-shaped, with its top connected to the first rod 1, preferably by a hinge. Optionally, the supporting base 7 is provided with a clamping cavity 71, which is a chamber located between the top plate and the bottom plate of the supporting base 7. When the clamping cavity 71 is closed, the entire supporting base 7 is in a working state of clamping the decontamination structure; when the clamping cavity 71 is open, the entire supporting base 7 is in a state where the decontamination structure can be easily removed and replaced.

[0086] Optionally, the clamping cavity 71 has a built-in elastic structure, which can clamp and remove the decontamination structure under the action of the elastic structure. The elastic structure may include at least a spring, which can generate an elastic clamping force. The elastic clamping force and the force on the first connecting part when the opening and closing member is driven to move can control the clamping cavity to switch from closed to open.

[0087] For example, since the movement of the first connecting part can control the state switching of the supporting base 7, the first connecting part can control the clamping cavity 71 to switch from closed to open. Furthermore, since the clamping cavity 71 needs to clamp and remove the cleaning structure under the action of the elastic structure, the first connecting part can be drivenly connected to the elastic structure. That is, the movement of the first connecting part can control the action of the elastic structure, thereby controlling the clamping cavity 71 to switch from closed to open. Specifically, a trigger 72 is provided at the end of the first connecting part away from the second connecting part. The trigger 72 can extend into the supporting base 7 and be drivenly connected to the elastic structure. When the opening / closing member is driven to move along the axial direction of the rod, the first connecting part moves in the same direction, causing the trigger 72 to move in the same direction as well. The movement of the trigger 72 can trigger the elastic structure, so that the elastic clamping force generated by the elastic structure and the force received by the first connecting part can control the clamping cavity to switch from closed to open. The specific shape of the trigger 72 is set according to the clamping cavity 71, and can be cylindrical or prismatic with a guide bevel.

[0088] As an alternative implementation, the clamping cavity 71 may be equipped with a structure such as an electric gripper, the switch of which is connected to the first connecting part.

[0089] Optional, such as Figure 1 and Figure 3 As shown, a toggle member 75 is provided on the lower side of the top plate of the supporting base 7. The toggle member 75 is located in the clamping cavity 71, and the trigger member 72 can be connected to the toggle member 75. Since the trigger member 72 needs to be driven to be connected to the elastic structure, the trigger member 72 can be driven to be connected to the elastic structure through the toggle member 75. When the opening and closing member is driven to move along the axial direction of the rod, the first connecting part moves in the same direction, driving the trigger member 72 to move towards the top plate of the supporting base 7. The movement of the trigger member 72 can drive the toggle member 75 to move. Since the toggle member 75 is driven to be connected to the elastic structure, the movement of the toggle member 75 can trigger the elastic structure, so as to control the clamping cavity 71 to switch from closed to open.

[0090] The cleaning device provided by this invention divides the rod into a first rod body 1 and a second rod body, and the opening and closing component into a first connecting part and a second connecting part 4, which are respectively disposed in the first rod body 1 and the second rod body. The first connecting part and the second connecting part 4 only connect to form the opening and closing component when the first rod body 1 and the second rod body are connected. On one hand, this achieves a solution where the first rod body 1 and the second rod body can be transported separately, and the first connecting part and the second connecting part 4 can connect to form an opening and closing component that drives the state switching of the bearing base 7 during use. This avoids the situation where the rod body cannot be disassembled for transport due to the need for an opening and closing component, overcomes the problem in the prior art where the rod body is restricted by the opening and closing component, making it difficult to achieve convenient disassembly, and solves the defect that long rod bodies are not conducive to daily storage and product transportation. It also makes the installation of the first rod body and the second rod body more convenient during use. On the other hand, after the first rod body 1 and the second rod body are connected, the connection of the first connecting part and the second connecting part 4 can achieve double limiting of the first rod body 1 and the second rod body, improving the connection tightness of the first rod body 1 and the second rod body, and ensuring the stability of the cleaning device during use.

[0091] In one feasible implementation, the first connecting part includes a transmission member 73 and an opening / closing body 74. The opening / closing body 74 is disposed inside the first rod body 1 and is used to connect with the second connecting part 4; one end of the transmission member 73 is connected to the opening / closing body 74, and the other end is connected to the bearing base 7; the opening / closing body 74 can be used to drive the transmission member 73 to move when driven, so that the transmission member 73 can control the bearing base 7 to switch from the working state to the replacement state.

[0092] For example, when the first rod 1 and the second rod are connected, the opening / closing body 74 is connected to the second connecting part 4, such that the second connecting part 4, the opening / closing body 74, and the transmission member 73 form an opening / closing member. Optionally, the opening / closing body 74 can be detachably connected to the second connecting part 4.

[0093] Optionally, the opening / closing body 74 can be detachably connected to the transmission component 73. For example... Figure 4 As shown, the opening and closing body 74 may be provided with an opening and closing limiting cavity 741, and an opening and closing through hole 742 is provided near the bottom wall of the transmission member 73. The end of the transmission member 73 can pass through the opening and closing through hole 742 and be limited in the opening and closing limiting cavity 741. When disassembly is required, the end of the transmission member 73 can be dislodged from the opening and closing through hole 742.

[0094] The end of the transmission component 73 may also be provided with an opening and closing limiting block 731, and the side wall of the opening and closing limiting cavity 741 has an opening; the opening and closing limiting block 731 can be inserted into the opening and closing limiting cavity 741 through the opening and closing limiting cavity 741 and abut against the bottom wall of the opening and closing limiting cavity 741 for limiting. Optionally, the opening and closing through hole 742 also has an opening on the side corresponding to the opening of the opening and closing limiting cavity 741. When the transmission component 73 needs to be connected to the opening and closing body 74, the opening and closing limiting block 731 can be inserted into the opening and closing limiting cavity 741 through the opening of the opening and closing limiting cavity 741, and the transmission component 73 can enter the opening and closing through hole 742 through the opening of the opening and closing through hole 742, so that the opening and closing limiting block 731 abuts against and limits the bottom wall of the opening and closing limiting cavity 741 where the opening and closing through hole 742 is provided. When the transmission component 73 needs to be separated from the opening and closing body 74, the opening and closing limiting block 731 can disengage from the opening and closing limiting cavity 741, and the transmission component 73 can also disengage from the opening and closing through hole 742 through the opening and closing through hole 742, so that the transmission component 73 is disengaged from the opening and closing body 74.

[0095] Optionally, the opening and closing body 74 may be provided with a plurality of opening and closing limiting cavities 741 along the axial direction of the first rod 1; the end of the transmission member 73 is limited in any one of the plurality of opening and closing limiting cavities 741. For example, the opening and closing body 74 may be in the shape of an elongated block, and the opening and closing limiting cavity 741 may be provided in the shape of a groove, with the opening formed on the side wall of the groove-shaped opening and closing limiting cavity 741 in the radial direction of the rod.

[0096] The transmission component 73 is used to adjust its length between the opening / closing body 74 and the supporting base 7 by means of end-limiting in different opening / closing limiting cavities 741. On the one hand, by selecting the opening / closing limiting cavity 741 that is limited by the opening / closing limiting block 731, the axial length of the transmission component 73 between the opening / closing body 74 and the supporting base 7 can be adjusted, which can achieve pre-tightening of the transmission component 73 and ensure smooth transmission; on the other hand, when the opening / closing limiting cavity 741 and the opening / closing limiting block 731 are disengaged, the opening / closing body 74 and the transmission component 73 can be structurally separated, which is convenient for subsequent component replacement and maintenance.

[0097] For example, the transmission component 73 can be a flexible component. When the opening and closing body 74 is driven to move away from the bearing base 7 along the axial direction of the rod, it can drive the transmission component 73 to move in the same direction, so that the transmission component 73 can control the bearing base 7 to switch from the working state to the replacement state. One end of the transmission component 73 extends into the bearing base 7 and is provided with a trigger 72, which is connected to the bearing base 7. The other end passes through the first rod 1. After the second connecting part 4 and the first connecting part are connected to each other, when an external force is applied to drive both to move away from the bearing base 7 along the axial direction of the rod, the transmission component 73 can transmit the driving force to the trigger 72 through tension, so that the trigger 72 can control the clamping cavity 71 to switch from closed to open. At the same time, when the bearing base 741 is hinged to the first rod 1 and needs to be rotated to a stacked state for storage, the transmission component 73 can be bent accordingly without disassembly.

[0098] In one feasible implementation, such as Figure 8 As shown, the first rod 1 includes a hollow first rod body 11 and a receiving cavity 12 formed by the hollow portion of the first rod body 11. The receiving cavity 12 has an opening at one end away from the supporting base 7. An opening / closing body 74 is disposed within the receiving cavity 12. A transmission hole 121 is provided on the bottom wall of the receiving cavity 12, and a transmission member 73 passes through the transmission hole 121 and connects to the supporting base 7. Optionally, one end of the flexible transmission member 73 is connected to the opening / closing body 74, and the other end extends into the supporting base 7 through the transmission hole 121, and is connected to the elastic structure of the supporting base 7 via a trigger member 72.

[0099] For example, the receiving cavity 12 is provided with a first limiting groove 15, in which the opening and closing body 74 is accommodated. The first limiting groove 15 is used to limit the circumferential and radial direction of the opening and closing body 74, ensuring the accurate position of the opening and closing body 74 and facilitating accurate docking with the second connecting part. The transmission hole 121 penetrates the bottom of the first limiting groove 15 and the bottom wall of the receiving cavity 12, facilitating the transmission component 73 to pass through the transmission hole and connect with the bearing base 7. Optionally, the first limiting groove 15 is located at the bottom of the receiving cavity 12, and the bottom of the first limiting groove 15 is the bottom wall of the receiving cavity 12.

[0100] Optionally, the end of the opening and closing body 74 away from the transmission member 73 can extend out of the first limiting groove 15 to facilitate connection with the second connecting part.

[0101] For example, the first connecting part also includes a limiting engagement part 743 disposed near one end of the second connecting part 4. That is, the limiting engagement part 743 can be disposed at the end of the opening and closing body 74 away from the transmission member 73. The limiting engagement part 743 can extend out of the first limiting groove 15, thus preventing the first limiting groove from limiting the limiting engagement part 743, so that the limiting engagement part 743 and the second connecting part can be detachably connected when the first rod 1 and the second rod are connected. As an alternative implementation, the two can be threaded structures and connected by threads, or they can be in the form of snaps and grooves.

[0102] like Figure 4 and Figure 5 As shown, one of the second connecting part 4 and the limiting engagement part 743 is provided with a spring arm gripper, and the other is provided with a barb; when the first rod body 1 and the second rod body are connected, the barb extends into the spring arm gripper and engages with the spring arm gripper.

[0103] Specifically, this embodiment is illustrated by taking the limiting engagement part 743 as having a spring arm gripper and the second connecting part 4 as having a barb. The spring arm gripper can extend out of the first limiting groove 15 to facilitate connection with the barb, thereby avoiding the situation where the spring arm gripper cannot deform due to the limitation of the first limiting groove 15 on the spring arm gripper, and thus cannot be connected with the barb.

[0104] The spring-loaded gripper includes two spring arms 7431 arranged radially opposite to each other along the rod. Each spring arm 7431 has a limiting hook 7432 protruding from its top end toward the central axis of the rod. The limiting hook 7432 has an inclined first guide surface on the side away from the spring arm and a first abutment surface on the side closer to the spring arm. The barb 46 is triangular, with its apex near the limiting engagement part 743. When the first rod 1 and the second rod are connected, the triangular barb 46 extends between the two spring arms 7431. Under the action of the first guide surface of the limiting hook 7432 at the top of the two spring arms 7431, the two spring arms 7431 move away from each other to avoid the triangular barb 46 until the bottom surface of the triangular barb 46 passes the limiting hook 7432. At this point, the two spring arms 7431 move closer together, causing the first abutment surface to abut against the bottom surface of the triangular barb 46, thus limiting the triangular barb 46.

[0105] In one feasible implementation, the second connecting portion 4 includes a base 41, a first limiting end 42, and a second limiting end 43.

[0106] The base 41 is rod-shaped. The second limiting end 43 is located at the end of the base 41 facing the first connecting part and is connected to the first connecting part. Specifically, the barb can be located at the second limiting end 43. The first limiting end 42 is located at the end of the base 41 away from the first connecting part and is movably connected to the second rod body. It is adapted to be driven to move along the axial direction of the second rod body and to drive the first connecting part to move in the same direction through the second limiting end 43, so that the first connecting part can control the load-bearing base 7 to switch from the working state to the replacement state.

[0107] Optionally, the first limiting end 42 is movably connected to the second rod body and can move along the axial direction of the second rod body under the drive of an external force. As an alternative implementation, the first limiting end 42 can extend out of the second rod body, and an external force is applied to the part that extends out; or, the first limiting end 42 is made of magnetic metal, and the external force controls the movement of the first limiting end 42 through magnetic force.

[0108] The second limiting end 43 and the limiting mating part 743 are detachably engaged and limited in the form of elastic claws and barbs. On the one hand, this arrangement allows the first connecting part to be driven by an external force after engagement, when the stress limit of the engagement limit is not exceeded, so that the second connecting part 4 can move along the axial direction of the rod, thereby realizing the state switching of the bearing base 7. On the other hand, when the pulling force on the first connecting part along the axial direction of the rod is further increased and exceeds the stress limit of the engagement limit of the second limiting end 43 and the limiting mating part 743, the two can be disengaged and disassembled.

[0109] For example, the second connecting portion 4 also includes an elastic reset member 45. One end of the elastic reset member 45 abuts against the base 41, and the other end abuts against the second rod. The elastic reset member 45 is used to reset the second connecting portion 4. Specifically, when the first limiting end 42 of the second connecting portion 4 is driven to move axially along the second rod and causes the base 41 to move in the same direction, the elastic reset member 45 stores force. When the driving force on the first limiting end 42 disappears, the elastic reset member 45 releases force and causes the base 41 to move in the opposite direction, causing the first limiting end 42 to reset, thereby resetting the second connecting portion 4.

[0110] For example, the second rod is provided with a guide portion 222, and when the first limiting end 42 is driven, it moves along the axial direction of the second rod under the guidance of the guide portion 222. The guide portion 222 can be provided on the side wall of the second rod and is arranged along the axial direction of the second rod, and is connected to the first limiting end 42 to guide the movement of the first limiting end 42.

[0111] Optionally, the first limiting end 42 is provided with a lateral limiting block 421 protruding radially along the rod. The guide portion 222 includes an elongated hole extending axially along the second rod. The lateral limiting block 421 extends out of the elongated hole from the inside to the outside to facilitate the user applying driving force. The lateral limiting block 421 is driven to slide along the elongated hole, causing the first limiting end 42 to move axially along the second rod. In addition, a number of reinforcing ribs are evenly distributed on the first limiting end 42.

[0112] For example, the cleaning device also includes a guide drive unit, which is sleeved on the outside of the second rod and connected to a lateral limiting block 421 extending from the elongated hole; the guide drive unit is used to drive the lateral limiting block to slide along the elongated hole. Optionally, the guide drive unit includes a guide drive body 223, which is sleeved on the outside of the second rod and has a limiting fitting hole 225 on its side wall, into which the lateral limiting block 421 extending from the elongated hole is inserted. The guide drive body 223 can slide along the outer periphery of the second rod when driven. When the guide drive body 223 slides along the outer periphery of the second rod, it can drive the lateral limiting block 421 to slide along the elongated hole, thereby driving the first limiting end 42 to move axially along the second rod.

[0113] The guide drive unit also includes a guide limiting member 224, which is disposed at the end of the guide drive body 223 away from the support base 7, so as to form a raised flange at the end. When the user needs to change the cleaning cloth or wiping cloth, he / she can hold the guide drive body 223 and pull it to make the guide drive body 223 slide along the outer periphery of the second rod away from the support base 7. At this time, the guide drive body 223 can drive the first limiting end 42 to move along the axial direction of the second rod away from the support base 7, thereby making the entire opening and closing part move in the same direction to control the support base 7 to switch from the working state to the replacement state. At this time, the flange formed by the guide limiting member 224 at the end of the guide drive body 223 away from the support base 7 makes it easier for the user to apply force when pulling the guide drive body 223.

[0114] Specifically, the guide limiter 224 can be threadedly connected to the guide drive body 223.

[0115] In another embodiment, the guide limiter 224 can be used to tighten or loosen the guide drive body 223 radially. By tightening or loosening the guide limiter 224, the position of the guide drive body 223 along the rod can be controlled, thereby achieving effective control of the position of the second connection portion 4.

[0116] Optionally, the second rod includes a second rod body 2 and a connecting rod 3. The connecting rod 3 includes a connecting main rod 31 and a connecting end 32. The connecting main rod 31 is connected to the second rod body 2, and the connecting end 32 is located at the end of the connecting main rod 31 away from the second rod body 2. The connecting end 32 has a built-in through hole that extends into the connecting main rod 31. The base 41 passes through the through hole, so that the first limiting end 42 and the second limiting end 43 are respectively located on both sides of the through hole. When the first rod body 1 and the second rod body are connected, the connecting end 32 extends into the first rod body 1, so that the second limiting end 43 is connected to the first connecting part.

[0117] In this embodiment, the second connecting part 4 is disposed in the second rod body. Specifically, the second connecting part 4 is partially disposed in the second rod body 2 and partially disposed in the connecting rod 3. As an alternative implementation, the second connecting part 4 can also be completely disposed in the connecting rod 3. The first limiting end 42 is movably connected to the second rod body 2 and is suitable for moving along the axial direction of the second rod body 2 under the action of external force. The connecting rod 3 is disposed at the end of the second rod body 2 that faces the opening on the first rod body 1.

[0118] For example, the first rod 1 includes a first rod body 11 and a receiving cavity 12. When the first rod 1 and the second rod are connected, the connecting end 32 can be inserted into the receiving cavity 12 and detachably connected to the receiving cavity 12, and then detachably connected to the first rod body 11.

[0119] For example, a second limiting protrusion 44 protrudes from the outer periphery of the base 41, and this second limiting protrusion 44 is close to the second limiting end 43. One end of the elastic reset member 45 abuts against the second limiting protrusion 44, and the other end abuts against the inner wall of the connecting end 32, which has a through hole. At this time, the inner wall of the connecting end 32 with the through hole abuts against the elastic reset member 45, and cooperates with the second limiting protrusion 44 to limit the elastic reset member 45 from both ends. When the second connecting part 4 moves away from the bearing base 7 along the circumference of the second rod, the second limiting protrusion 44 moves towards the inner wall of the connecting end 32 with the through hole, and at this time the elastic reset member 45 is compressed and stores force. When the elastic reset member 45 extends to release the force, it can drive the second connecting part 4 to reset.

[0120] For example, the first rod 1 and the second rod can be detachably connected by a connecting limiting unit, which includes a first limiting part and a second limiting part, adapted to detachably limit the connection between the first rod 1 and the second rod along the outside and inside of the sidewall of the rod. As an alternative implementation, only one of the first limiting part and the second limiting part may be provided.

[0121] Optionally, the first rod 1 and the second rod can be detachably connected by a first limiting part; the first limiting part is used to limit the first rod 1 and the second rod in the axial direction of the rod.

[0122] Optionally, the first limiting part includes a first limiting structure 33 and a first limiting mating structure 13; the first limiting structure 33 includes a first spring piece 331 disposed on the second rod and a first limiting protrusion 332 disposed at the end of the first spring piece 331; the first limiting mating structure 13 includes a first limiting hole disposed on the first rod 1; when the second rod extends into the first rod 1, the first limiting protrusion 332 is accommodated in the first limiting hole.

[0123] For example, after the first rod 1 is connected to the second rod, it is circumferentially limited by the second limiting part.

[0124] Optionally, the second limiting part includes a second limiting structure 34 and a second limiting mating structure 14; the second limiting structure 34 is disposed on the outer periphery of the second rod along the axial direction of the rod, and the second limiting mating structure 14 is disposed on the inner wall of the first rod 1 along the axial direction of the rod; when the second rod extends into the first rod 1, the second limiting structure 34 and the second limiting mating structure 14 cooperate to limit the circumferential direction of the first rod 1 and the second rod.

[0125] Optionally, one of the second limiting structure 34 and the second limiting mating structure 14 is a protrusion and the other is a groove; when the second rod extends into the first rod 1, the protrusion is inserted into the groove.

[0126] The following description uses the example of a first rod body 1 including a first rod shaft 11 and a receiving cavity 12, and a second rod body including a second rod shaft 2 and a connecting rod 3, wherein the connecting rod 3 includes a connecting main rod 31 and a connecting end 32:

[0127] The first limiting part includes a first limiting structure 33 and a first limiting mating structure 13. The first limiting structure 33 is disposed along the side wall of the connecting end 32, and the first limiting mating structure 13 is disposed along the inner wall of the receiving cavity 12, which is suitable for detachably limiting the connection of the first limiting structure 33. Specifically, the first limiting structure 33 includes a first spring piece 331 and a first limiting protrusion 332. A spring piece mounting hole is provided on the side wall of the connecting end 32. The first spring piece 331 is disposed on the spring piece mounting hole. The end of the first spring piece 331 facing the first rod 1 is connected to the inner edge of the spring piece mounting hole. The end of the first spring piece 331 away from the first rod 1 is not in contact with the inner edge of the spring piece mounting hole. The first limiting protrusion 332 is provided along the radial outer side of the connecting end 32. The first limiting mating structure 13 includes a first limiting hole. The first limiting hole is disposed on the inner wall of the receiving cavity 12 and passes through the first rod 1, and is suitable for receiving the first limiting protrusion 332.

[0128] The second limiting part includes: a second limiting structure 34 and a second limiting mating structure 14. The second limiting structure 34 is disposed on the connecting rod 3, and is circumferentially distributed along the side wall of the connecting end 32 of the connecting rod 3, with its length direction aligned with the axial direction of the connecting end 32. The second limiting mating structure 14 is disposed on the receiving cavity 12, and is circumferentially distributed along the inner wall of the receiving cavity 12, with its length direction aligned with the axial direction of the receiving cavity 12. The second limiting mating structure 14 and the second limiting structure 34 are mutually matched and mutually limited circumferentially. Specifically, the second limiting structure 34 is a protrusion, and the second limiting mating structure 14 is a groove. The second limiting structure 34 can also be a groove, and the second limiting mating structure 14 can also be a protrusion. Further, a plurality of second limiting structures 34 are evenly distributed circumferentially along the inner wall of the receiving cavity 12, and a plurality of second limiting mating structures 14 are evenly distributed circumferentially along the outer wall of the connecting end 32.

[0129] In this embodiment, the end of the connecting end 32 is rounded to facilitate connection with the first rod.

[0130] For example, the cleaning unit also includes a movable end 8, which is connected to both the support base 7 and the first rod 1; a first connecting portion passes through the movable end 8 and connects to the support base 7. Specifically, the end of the transmission member 73 can extend into the support base 7 through the movable end 8 and be connected to the support base 7 via a trigger member 72.

[0131] In this embodiment, the movable end 8 is hinged to both the bearing base 741 and the rod, or it can be hinged to either one of them. Further, the movable end 8 includes a first hinge structure 81 and a second hinge structure 82. The axes of the first hinge structure 81 and the second hinge structure 82 are perpendicular to each other. The first hinge structure 81 is hinged to the first rod 1, and the second hinge structure 82 is hinged to the bearing base 741.

[0132] As a variable implementation, the axis of the first hinge structure 81 and the axis of the second hinge structure 82 can be arranged to cross each other.

[0133] In one feasible implementation, the second shaft 2 may further include an upper shaft 21, a lower shaft 22, and a connecting sleeve 23. The end of the lower shaft 22 away from the upper shaft 21 is connected to the connecting rod 3. The connecting sleeve 23 accommodates the shaft ends of the upper shaft 21 and the lower shaft 22, and detachably connects the upper shaft 21 and the lower shaft 22. In this embodiment, the connecting sleeve 23 limits the movement of the upper shaft 21 and the lower shaft 22 through friction.

[0134] Optionally, the upper shaft 21 and lower shaft 22 are fitted together, with a spacer ring 231 inside the connecting sleeve 23. The upper shaft 21 is provided with a stepped shoulder 211, and the spacer ring 231 is clamped at the shaft end of the lower shaft 22. As an alternative implementation, the lower shaft 22 is provided with a stepped shoulder 211, and the spacer ring 231 is clamped at the shaft end of the upper shaft 21. By providing the spacer ring 231, the connection between the upper shaft 21 and the lower shaft 22 can be effectively protected.

[0135] The lower rod body 22 includes a lower rod main body 221 and a guide portion 222. The guide portion 222 can be disposed on the outer wall of the lower rod main body 221, arranged along the axial direction of the lower rod main body 221, and is connected to the first limiting end 42 to guide the movement of the first limiting end 42. A guide drive portion is sleeved on the outside of the lower rod main body 221, connected to the first limiting end 42, and movably connected to the lower rod main body 221, suitable for reciprocating movement along the axial direction of the lower rod main body 221 under external force.

[0136] The lower shaft 22 also includes a lower end limiting part 226, which is provided along the end of the lower shaft 22 toward the connecting end 32. The connecting main shaft 31 is nested with the lower shaft 22. The connecting end 32 also includes a lower end limiting fitting part 321, which is provided along the outer wall of the connecting end 32 and is fitted with the lower end limiting part 226 to limit the lower shaft 22.

[0138] As an alternative implementation, the lower limit part 226 and the lower limit mating part 321 may be omitted, and the main rod 31 and the lower rod body 22 may be connected by an interference fit.

[0139] Optionally, the rod also includes an end rod 6, which is disposed at the end of the second rod away from the first rod 1 and is detachably connected to the second rod.

The closed end 63 is detachably connected to the end body 61. In addition, the side of the closed end 63 away from the end body 61 is rounded.

[0142] For example, the cleaning device is a mop, the cleaning unit is the mop head, and the supporting base 7 is the board body of the mop head without a cleaning cloth or wiping cloth.

[0143] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
