Description

Technical Field

[0001] This application belongs to the technical field of household appliances, and particularly relates to an adapter assembly and a cleaning device. Background Art

[0002] For the cleaning devices on the market currently, the extension rod can be bent by setting joints to clean low and deep spaces such as under the bed and under the sofa. During the cleaning process, the cleaning device needs to be repeatedly moved to completely clean the ground covered by the areas under the bed and under the sofa. During the process of moving the cleaning device, the bending angle of the extension rod will also change accordingly.

[0003] For the existing cleaning devices, when the two ends of the extension rod become straight, the extension rod will automatically lock and no longer bend. If you want to continue cleaning under the bed and under the sofa, the user needs to manually adjust the joints multiple times to make the extension rod bendable, which increases the complexity of use and results in a poor user experience. Summary of the Utility Model

[0004] This application aims to at least solve to some extent the technical problems that the extension rod of the existing cleaning device is prone to automatic locking during the cleaning operation and the user experience is poor. For this purpose, this application provides an adapter assembly and a cleaning device.

[0005] In the first aspect of this application, an adapter assembly is provided, including:

[0006] A first joint and a second joint connected to the first joint;

[0007] A switch assembly, installed on the first joint or the second joint. When the switch assembly is in the first position, the first joint and the second joint can remain in an unlocked state; when the switch assembly is in the second position and the first joint and the second joint are rotated to a preset angle, the first joint and the second joint can remain in a locked state.

[0008] In some embodiments, the switch assembly includes:

[0009] A locking member, installed on the first joint or the second joint;

[0010] A triggering member, installed on the first joint or the second joint. The triggering member can drive the locking member to separate from at least one of the first joint and the second joint, so that the first joint and the second joint remain in an unlocked state; the triggering member can drive the locking member to connect with the first joint and the second joint, so that the first joint and the second joint remain in a locked state.

[0011] In some embodiments, the locking member includes a connecting portion, a locking portion, and a driving portion. The driving portion and the locking portion are respectively connected to two ends of the connecting portion. The connecting portion is rotatably connected to the first joint or the second joint. The trigger member has a driving portion that cooperates with the driving portion.

[0012] In some embodiments, the driving portion has a driving surface, the driving portion has a receiving surface, and the driving portion can operably bring the driving surface into contact with the receiving surface.

[0013] In some embodiments, when the trigger member is installed on the first joint, the first joint is provided with a stop portion, and the trigger member is provided with a protrusion portion. The stop portion can abut against the protrusion portion to make the trigger member located at the first position.

[0014] In some embodiments, the first joint has a limiting groove, the trigger member is installed in the limiting groove, and the stop portion is provided on the side wall or the bottom wall of the limiting groove.

[0015] In some embodiments, the stop portion protrudes toward the trigger member and has a guiding surface.

[0016] In some embodiments, under the condition that the locking member is installed on the first joint, the second joint is provided with a locking hole, and the locking member can be snap-connected with the locking hole to keep the first joint and the second joint in a locked state.

[0017] In some embodiments, the locking portion has a guiding surface. When the trigger member is in the second position and the first joint and the second joint rotate relative to each other, the second joint can slide relative to the guiding surface to make the locking member snap-connected with the locking hole.

[0018] In some embodiments, the trigger member is provided with a first guiding portion, and the first joint or the second joint is provided with a second guiding portion. The first guiding portion and the second guiding portion are slidably connected to make the trigger member slide between the first position and the second position.

[0019] In some embodiments, under the condition that the locking member is installed on the first joint, the switch assembly further includes a reset member. The reset member is disposed between the locking member and the first joint. When the trigger member is in the second position, the reset member can lock the first joint and the second joint by the locking member.

[0020] In some embodiments, the first joint is provided with a receiving cavity and a mounting opening communicating with the receiving cavity. At least a part of the locking member is mounted in the receiving cavity, a part of the triggering member is located outside the receiving cavity, and a part of the triggering member passes through the mounting opening.

[0021] In some embodiments, the first joint is provided with a mounting member, and the locking member is mounted on the mounting member.

DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0047] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0048] The suction head of the cleaning equipment currently on the market is hinged on the extension rod so that the user can keep the suction head facing the ground when using the cleaning equipment. However, due to the height limitations of the suction head and the handle, the cleaning equipment cannot cope with cleaning operations in low and deep spaces such as under beds and sofas. Therefore, some cleaning equipment provides a joint on the extension rod to make the extension rod bendable.

[0049] However, during the cleaning process, the cleaning device needs to be repeatedly moved to completely clean the ground covered by furniture such as beds and sofas. During the process of moving the cleaning device, the bending angle of the extension rod will also change accordingly. In the existing cleaning device, when the two ends of the extension rod become straight, the extension rod is automatically locked and no longer bends. If you want to continue cleaning under the bed and under the sofa, the user needs to manually adjust the joint multiple times to make the extension rod bend again, which increases the complexity of use. Moreover, the user needs to be vigilant during use to avoid the joint being locked again as much as possible, resulting in a poor user experience. The embodiments of the present application provide an adapter assembly and a cleaning device, which can at least solve the above technical problems to a certain extent. The adapter assembly and the cleaning device provided by the embodiments of the present application can reduce the number of adjustments during the use of the adapter assembly, reduce the situation of repeated unlocking, reduce the complexity of operation, and improve the user experience.

[0050] The following describes the present application with reference to the accompanying drawings and specific embodiments:

[0051] As Figures 1 - 16 shown, the embodiments of the present application provide an adapter assembly 10. The adapter assembly 10 provided by the embodiments of the present application can reduce the number of times of adjusting the switch assembly 300 during the use of the adapter assembly 10, reduce the situation of repeated unlocking, and reduce the complexity of operation.

[0052] As Figure 1 and Figure 2 shown, the adapter assembly 10 includes a first joint 100, a second joint 200 connected to the first joint 100, and a switch assembly 300. The switch assembly 300 is installed on the first joint 100 or the second joint 200. When the switch assembly 300 is in the first position, the first joint 100 and the second joint 200 can remain in an unlocked state; when the switch assembly 300 is in the second position and the first joint 100 and the second joint 200 are rotated to a preset angle, the first joint 100 and the second joint 200 can remain in a locked state.

[0053] Both the first joint 100 and the second joint 200 are structural members, which are respectively used to connect other structural components. The structural components can be rod-shaped members, tubular members, the main body of the cleaning device, the cleaning part, etc. The relative positions between the first joint 100 and the second joint 200 can be fixed or changed, so that the other structural components connected by the first joint 100 and the second joint 200 can present different states; the first position and the second position are respectively the positions that the switch assembly 300 can reach. By switching the switch assembly 300 between the first position and the second position, the first joint 100 and the second joint 200 can be switched between the unlocked state and the locked state.

[0054] The first joint 100 and the second joint 200 are connected, and the connection methods include but are not limited to hinged connection, pivotal connection, ball joint connection, sliding connection or a combination of the above. There is no clear restrictive relationship between the first joint 100 and the second joint 200, so it is feasible for the trigger member 320 and the locking member 310 to be set at the first joint 100 or the second joint 200.

[0055] like Figure 3 and Figure 4 As shown, when the switch assembly 300 is in the first position, the first joint 100 and the second joint 200 can remain in the unlocked state. In the unlocked state, the relative position between the first joint 100 and the second joint 200 can change with the driving of the external force. In the process of the relative position between the first joint 100 and the second joint 200 changing, the first joint 100 and the second joint 200 in the unlocked state will not be locked in the process of the relative position between the two changing. That is, by setting the switch assembly 300 in the adapter assembly 10, the state between the first joint 100 and the second joint 200 can be switched between the unlocked state and the locked state through the switch assembly 300 and is not easy to be in the locked state, so that the device using the adapter assembly 10 can adapt to a variety of usage scenarios.

[0056] For example, when the adapter component 10 is applied to a cleaning device, one of the first joint 100 and the second joint 200 is connected to the main unit of the cleaning device, and the other is connected to the cleaning unit of the cleaning device. The user can hold the main unit to clean the object to be cleaned. During the cleaning process, the cleaning may be performed on low-height and deep cleaning scenes such as the bottom of a sofa and a bed. Therefore, during the cleaning process, the angle of the cleaning unit and the angle between the main unit need to change to adapt to different cleaning scenes.

[0057] During the cleaning process, the switch assembly 300 can be placed in the first position, that is, the first joint 100 and the second joint 200 are always kept unlocked. During the cleaning process, no matter how the angle between the cleaning unit and the main unit changes, the first joint 100 and the second joint 200 will not be locked, that is, the positional relationship between the cleaning unit and the main unit will not be locked, and the angle between the cleaning unit and the main unit can be adjusted arbitrarily to adapt to application scenarios with low height and deep depth. During the cleaning process, the first joint 100 and the second joint 200 are always kept unlocked, and there is basically no situation where the first joint 100 and the second joint 200 are locked due to the rotation of the cleaning unit and the main unit to a certain angle, which reduces the repeated unlocking operations during the cleaning process and improves the user experience.

[0058] When the switch assembly 300 is in the second position and the angle between the first joint 100 and the second joint 200 is not within the preset angle, the relative position between the first joint 100 and the second joint 200 can still change.

[0059] Among them, there is a change in the angle between the first joint 100 and the second joint 200. Thus, the angle formed after the extension line of the length direction of the first joint 100 intersects with the extension line of the length direction of the second joint 200 is the angle between the first joint 100 and the second joint 200.

[0060] As Figure 5 shown, when the angle between the first joint 100 and the second joint 200 is within the preset angle, the switch assembly 300 will cause the first joint 100 and the second joint 200 to be in a locked state. In the locked state, the relative position between the first joint 100 and the second joint 200 will remain unchanged and will not change with the drive of an external force.

[0061] After setting the switch assembly 300 to the second position, then rotating the first joint 100 and the second joint 200 to the preset angle can make the adapter assembly 10 remain in the locked state. Of course, it is also possible to rotate the first joint 100 and the second joint 200 to the preset angle and then set the switch assembly 300 to the second position, which can also make the first joint 100 and the second joint 200 remain in the locked state.

[0062] That is, if the cleaning device is no longer in use or the working scenario no longer requires the adapter assembly to be in the unlocked state, the switch assembly 300 can be placed in the second position to make the first joint 100 and the second joint 100 move relative to each other. When the first joint 100 and the second joint 200 are rotated to the preset angle, the first joint 100 and the second joint 200 are locked to each other, making the cleaning part and the host form a whole, which is convenient for the storage of the entire cleaning device or its use at the preset angle.

[0063] It is easy to understand that when the switch assembly 300 is in the second position, the first joint 100 and the second joint 200 can be in an unlocked state or a locked state. The state between the first joint 100 and the second joint 200 can be changed by adjusting the angle between the first joint 100 and the second joint 200. That is, when the angle between the first joint 100 and the second joint 200 is adjusted to a preset angle, the first joint 100 and the second joint 200 are switched from the unlocked state to the locked state. When the first joint 100 and the second joint 200 need to be switched from the locked state to the unlocked state, the switch assembly 300 needs to be switched from the second position to the first position. When it is necessary to switch from the unlocked state to the locked state, the switch assembly 300 needs to be switched from the first position to the second position and the angle between the first joint 100 and the second joint 200 is adjusted so that the first joint 100 and the second joint 200 are switched from the unlocked state to the locked state.

[0064] Through the cooperation of the switch assembly 300 with the first joint 100 and the second joint 200, when the switch assembly 300 is in the first position, the entire adapter assembly 10 will remain in the unlocked state. During use, regardless of how the included angle between the first joint 100 and the second joint 200 changes, the first joint 100 and the second joint 200 will not be locked, and it is possible to avoid as much as possible the situation where the first joint 100 and the second joint 200 are locked due to the change in the included angle between the first joint 100 and the second joint 200 during use, reduce the number of times of adjusting the switch assembly 300 during the use of the adapter assembly 10, reduce the situation of repeated unlocking, reduce the cumbersome degree of operation, and the user experience is good. If it is necessary to lock the first joint 100 and the second joint 200, only need to set the switch assembly 300 in the second position and make the included angle between the first joint 100 and the second joint 200 be at the preset angle, then the first joint 100 and the second joint 200 can be locked, the operation is simple, and the user experience is greatly improved.

[0065] In some embodiments, the movement angle between the first joint 100 and the second joint 200 is 0 - 180°.

[0066] The movement angle is the included angle between the first joint 100 and the second joint 200 during the relative movement of the first joint 100 and the second joint 200. When the first joint 100 and the second joint 200 are in the unlocked state, the first joint 100 and the second joint 200 can perform arbitrary relative movement within the movement angle, with high flexibility.

[0067] The movable angle between the first joint 100 and the second joint 200 is 0-180°, wherein when the angle between the first joint 100 and the second joint 200 is 0°, the first joint 100 and the second joint 200 are in a folded state, and the length of the adapter assembly 10 will be shortened for easy storage; when the angle between the first joint 100 and the second joint 200 is greater than 0°, the first joint 100 and the second joint 200 are in an open state, and the first joint 100 and the second joint 200 can rotate arbitrarily within the movable angle, which is convenient for coping with different usage scenarios.

[0068] For example, one of the first joint 100 and the second joint 200 is connected to a main body of the cleaning device, and the other one is connected to a cleaning part of the cleaning device.

[0069] By rotating the first joint 100 and the second joint 200 so that the angle between the first joint 100 and the second joint 200 is 0°, the main body and the cleaning part of the cleaning device can be located on the same side of the adapter assembly 10, thereby lowering the height of the cleaning device so that the cleaning device can be easily stored in a shorter storage space. Of course, the height of the outer packaging used to package the cleaning device is also correspondingly shorter, thereby reducing the packaging cost.

[0070] When using the cleaning device, the 0-180° active angle also allows the cleaning part to fit the bottom surface as closely as possible when the user operates the main unit, ensuring the cleaning effect.

[0071] It should be noted that, when the first joint 100 and the second joint 200 are in an unlocked state, the preset angle does not affect the relative movement between the first joint 100 and the second joint 200. For example, the preset angle is 90°. When the first joint 100 and the second joint 200 are in a locked state, and the angle between the first joint 100 and the second joint 200 is 90°, the cleaning device equipped with the adapter assembly 10 can be applied to some scenes that require a right angle bend between the main unit and the cleaning unit, such as vacuuming operations on a house ceiling. For another example, the preset angle is 180°. When the first joint 100 and the second joint 200 are in a locked state, and the angle between the first joint 100 and the second joint 200 is 180°, the cleaning device equipped with the adapter assembly 10 can be applied to some scenes that require a straight line between the main unit and the cleaning unit, such as vacuuming operations on ordinary floors. Regardless of whether the preset angle is 45°, 60°, 90°, 120°, 150° or any other angle, as long as the first joint 100 and the second joint 200 are switched from a locked state to an unlocked state through the switch assembly 300, the first joint 100 and the second joint 200 can still move relative to each other within an active angle of 0-180°, the main unit and the cleaning unit have high flexibility, and the user experience is good.

[0072] Of course, in some other embodiments, the angle of movement between the first joint 100 and the second joint 200 is 90 - 180°.

[0073] At this time, the minimum value of the included angle between the first joint 100 and the second joint 200 is 90°. When the first joint 100 and the second joint 200 are in the unlocked state, the first joint 100 and the second joint 200 can rotate arbitrarily within 90 - 180°.

[0074] For example, one of the first joint 100 and the second joint 200 is connected to the main body of the cleaning device, and the other is connected to the cleaning part of the cleaning device.

[0075] When the first joint 100 and the second joint 200 are in the unlocked state, when the user holds the main body and moves the cleaning device for cleaning operations, the user holds the main body and pushes or drags the main body to move. The force applied by the user to the main body is transmitted to the cleaning part through the transfer assembly 10, so that the cleaning part moves. The first joint 100 and the second joint 200 can only rotate within 90 - 180°, that is, the cleaning device will not be in a folded state. No matter how the user pushes or drags the main body, the cleaning part can be driven to move in the direction of the force applied by the user. At the same time, when performing dust suction operations on the ceiling of a house, it is not necessary to lock the first joint 100 and the second joint 200 through the switch assembly 300. The user's operation of the cleaning device is more convenient and the experience is good.

[0076] Of course, in some embodiments, the angle of movement between the first joint 100 and the second joint 200 can also be in intervals such as 60 - 180°, 90 - 210°, 90 - 270°, 0 - 270°, etc. Different angles of movement in cooperation with different preset angles can enable the transfer assembly to adapt to the application scenarios of a variety of devices.

[0077] As Figure 6 shown, in some embodiments, the first joint 100 is provided with a receiving cavity 130 and a mounting opening 140 communicating with the receiving cavity 130. At least part of the locking member 310 is installed in the receiving cavity 130, and part of the triggering member 320 is located outside the receiving cavity 130, and part of the triggering member 320 passes through the mounting opening 140.

[0078] The locking member 310 can be installed in the receiving cavity 130. By disposing the locking member 310 in the receiving cavity 130, the exposure of parts can be reduced, the possibility of the parts being accidentally touched or damaged can be lowered, the comfort of the user during the use of the adapter assembly 10 can be improved, and at the same time, the neatness of the exterior of the adapter assembly 10 can be enhanced. Of course, the portion of the locking member 310 for contacting the triggering member 320 can be located within the mounting opening 140 to shorten the length of the portion of the triggering member 320 passing through the mounting opening 140. At this time, part of the locking member 310 is located within the receiving cavity 130. Part of the triggering member 320 is located outside the receiving cavity 130, enabling the user to manually operate the triggering member 320 to achieve the change of the state between the first joint 100 and the second joint 200.

[0079] In some embodiments, the switch assembly 300 includes a locking member 310 and a triggering member 320. The locking member 310 is installed on the first joint 100 or the second joint 200, and the triggering member 320 is installed on the first joint 100 or the second joint 200. The triggering member 320 can drive the locking member 310 to separate from at least one of the first joint 100 and the second joint 200, so that the first joint 100 and the second joint 200 remain in an unlocked state. The triggering member 320 can drive the locking member 310 to connect with the first joint 100 and the second joint 200, so that the first joint 100 and the second joint 200 remain in a locked state. Specifically, when the triggering member 320 is in the first position, the locking member 310 can separate from the first joint 100 and the second joint 200, so that the first joint 100 and the second joint 200 remain in an unlocked state. When the triggering member 320 is in the second position and the first joint 100 and the second joint 200 are rotated to a preset angle, the locking member 310 can connect with the first joint 100 and the second joint 200, so that the first joint 100 and the second joint 200 remain in a locked state.

[0080] Among them, the first position that the triggering member 320 can reach is the first position that the switch assembly 300 can reach, and the second position that the triggering member 320 can reach is the second position that the switch assembly 300 can reach.

[0081] The switch member 300 includes a locking member 310 and a triggering member 320. That is, the relative position between the locking member 310 and the triggering member 320 can be adaptively set according to the connection manner between the first joint 100 and the second joint 200, so that the triggering member 320 can drive the locking member 310 to lock the first joint 100 and the second joint 200 more smoothly and will not affect the relative movement between the first joint 100 and the second joint 200.

[0082] Among them, the locking member 310 is installed on the first joint 100 or the second joint 200, and the triggering member 320 is installed on the first joint 100 or the second joint 200. It is possible that the locking member 310 and the triggering member 320 are both set on the first joint 100, or the locking member 310 and the triggering member 320 are both set on the second joint 200. It is also possible that the locking member 310 and the triggering member 320 are respectively set on the first joint 100 or the second joint 200. The specific installation positions of the locking member 310 and the triggering member 320 may not be limited, as long as the functions of locking and unlocking the first joint 100 and the second joint 200 can be achieved.

[0083] As Figure 6 shown, when the triggering member 320 is in the first position, the locking member 310 can be separated from the first joint 100 and the second joint 200, keeping the first joint 100 and the second joint 200 in an unlocked state. In the unlocked state, regardless of how the relative positions between the first joint 100 and the second joint 200 change, the first joint 100 and the second joint 200 will not be locked.

[0084] As Figure 7 shown, when the triggering member 320 is in the second position and the first joint 100 and the second joint 200 are rotated to a preset angle, the locking member 310 can be connected to the first joint 100 and the second joint 200, keeping the first joint 100 and the second joint 200 in a locked state. Specifically, when the triggering member 320 is in the second position, the included angle between the first joint 100 and the second joint 200 is not within the preset angle, and the locking member 310 will not lock the first joint 100 and the second joint 200. The relative positions between the first joint 100 and the second joint 200 can still change, and at this time, the first joint 100 and the second joint 200 are still in an unlocked state. When the included angle between the first joint 100 and the second joint 200 reaches the preset angle, the locking member 310 locks the first joint 100 and the second joint 200. When the triggering member 320 is in the second position and the included angle between the first joint 100 and the second joint 200 is within the preset angle, the locking member 310 can lock the first joint 100 and the second joint 200, and the relative positions between the first joint 100 and the second joint 200 will no longer change with the drive. At this time, the first joint 100 and the second joint 200 are in a locked state.

[0085] As Figure 6 、 Figure 7 and Figure 8As shown, in some embodiments, the locking member 310 includes a connecting portion 311, a locking portion 312, and a driving portion 313. The driving portion 313 and the locking portion 312 are respectively connected to two ends of the connecting portion 311. The connecting portion 311 is rotatably connected to the first joint 100 or the second joint 200. The triggering member 320 has a driving portion 321. The locking member 310 is disposed on the first joint 100 or the second joint 200. The connecting portion 311 can rotate around the first joint 100 or the second joint 200, and the driving portion 313 and the locking portion 312 are respectively located at two ends of the locking member 310.

[0086] It can be understood that the locking member 310 is a lever structure, the connecting portion 311 is the fulcrum, the driving portion 313 and the driving portion 321 are respectively located on two force arms of the lever structure. When the driving portion 321 abuts against the driving portion 313, when the driving portion 313 is stressed and rotates around the connecting portion 311 in one direction, the locking portion 312 rotates around the connecting portion 311 in the opposite direction.

[0087] The locking member 310 adopts a lever structure. If the length of the force arm where the driving portion 313 is located is less than the length of the force arm where the locking portion 312 is located, the moving path when the triggering member 320 drives the locking member 310 is shorter, and the space occupied by installing the driving portion 313 is correspondingly reduced, which is more suitable for the small-sized adapter assembly 10. If the length of the force arm where the driving portion 313 is located is greater than the length of the force arm where the locking portion 312 is located, a smaller force can be used to make the triggering member 320 drive the locking member 310, and it is not laborious for the user to push the triggering member 320, and the comfort during use is high.

[0088] In the present application, for the convenience of description, in the following embodiments, the entire locking member 310 and the triggering member 320 are set on the first joint 100 as an example for illustration, and it can be analogized when the locking member 310 and the triggering member 320 are set on the second joint 200.

[0089] When the driving portion 313 rotates around the connecting portion 311 and approaches the second joint 200, the locking portion 312 moves away from the second joint 200 under the lever action. When the driving portion 313 rotates around the connecting portion 311 and moves away from the second joint 200, the locking portion 312 approaches the second joint 200 under the lever action.

[0090] In the case where the triggering member 320 is in the first position, the driving portion 321 can abut against the driving portion 313, and the locking portion 312 located on the other force arm of the locking member 310 is separated from the second joint 200, so that the first joint 100 and the second joint 200 are kept in an unlocked state.

[0091] When the driving portion 321 pushes against the bearing portion 313 to move toward the second joint 200, the locking portion 312 moves toward the second joint 200 until the locking portion 312 is separated from the second joint 200. The restriction of the locking portion 312 on the first joint 100 and the second joint 200 disappears, and the locking portion 312 will no longer lock the first joint 100 and the second joint 200. At this time, the first joint 100 and the second joint 200 are in an unlocked state.

[0092] In the unlocked state, the first joint 100 and the second joint 200 are relatively rotatable. When the first joint 100 and the second joint 200 are not rotated to the preset angle, there is also an angle between the outer wall of the first joint 100 and the outer wall of the second joint 200, and the locking portion 312 is not in a condition capable of connecting the first joint 100 and the second joint 200. In this state, the first joint 100 and the second joint 200 are still relatively rotatable.

[0093] When the trigger member 320 is in the second position, the driving part 321 can be separated from the bearing part 313, and when the first joint 100 and the second joint 200 are rotated to a preset angle, the locking part 312 can be connected to the first joint 100 and the second joint 200 to keep the first joint 100 and the second joint 200 in a locked state.

[0094] When the first joint 100 and the second joint 200 rotate to a preset angle, the locking portion 312 will further rotate toward the second joint 200 and finally connect with the second joint 200. The locking portion 312 restricts the first joint 100 and the second joint 200. Even when the first joint 100 or the second joint 200 is subjected to force, relative rotation will no longer occur. At this time, the adapter assembly 10 is in a locked state.

[0095] As described above, the locking member 310 has a connecting portion 311, a locking portion 312 and a supporting portion 313, and has a simple structure. The user only needs to cooperate the trigger member 320 with the supporting portion 313 to make the locking portion 312 lock the first joint 100 and the second joint 200 or make the locking portion 312 disengage from the second joint 200. The operation is simple and the user experience is good.

[0096] In some embodiments, the driving portion 321 has a driving surface 3211, and the bearing portion 313 has a bearing surface 3131. When the trigger member 320 slides in the first direction, the driving surface 3211 can contact the bearing surface 3131 and push the bearing portion 313 to move toward the second joint 200, so that the locking portion 312 can move away from the second joint 200, so that the first joint 100 and the second joint 200 are no longer restricted and are in an unlocked state.

[0097] During the process of the trigger 320 moving in the second direction, the driving part 321 can cause the driven part 313 to move away from the second joint 200, so that under the lever action of the trigger 310, the locking part 312 can move towards the second joint 200. The locking part 312 connects the first joint 100 and the second joint 200 and locks the first joint 100 and the second joint 200 in a locked state.

[0098] In some embodiments, when the locking member 310 is installed on the first joint 100, the second joint 200 is provided with a locking hole 210, and the locking member 310 can be engaged with the locking hole 210 to keep the first joint 100 and the second joint 200 in a locked state.

[0099] Specifically, when the included angle between the first joint 100 and the second joint 200 is a preset angle, the positions of the locking hole 210 and the locking part 312 match, and the locking part 312 can be engaged into the locking hole 210. When the trigger 320 is in the second position, the locking part 312 will remain engaged in the locking hole 210, and the first joint 100, the second joint 200 and the locking part 312 are connected. At this time, the first joint 100 and the second joint 200 are in a locked state; when the included angle between the first joint 100 and the second joint 200 is not the preset angle, the positions of the locking hole 210 and the locking part 312 are misaligned. At this time, the locking part 312 will not be engaged into the locking hole 210, and the locking part 312 will not limit the relative position between the first joint 100 and the second joint 200, and the first joint 100 and the second joint 200 are in an unlocked state.

[0100] In order to facilitate the first joint 100 and the second joint 200 to smoothly rotate to the preset angle, in some embodiments, the locking part 312 has a guiding surface 3121. When the trigger 320 is in the second position and the first joint 100 and the second joint 200 rotate relative to each other to the preset angle, the second joint 200 can slide relative to the guiding surface 3121 so that the locking part 312 is engaged with the locking hole 210. At this time, the engagement between the locking member 310 and the locking hole 210 is completed.

[0101] The guiding surface 3121 can be an arc surface or an inclined surface. When the first joint 100 and / or the second joint 200 rotates, at least part of the hole wall of the locking hole 210 can abut against the guiding surface 3121 and move along the guiding surface 3121, reducing the jamming situation during the rotation of the first joint 100 and the second joint 200, and improving the user experience of rotating the adapter assembly 10.

[0102] Among them, the first direction refers to the direction of moving from the second position to the first position, and the second direction refers to the direction of moving from the first position to the second position. The specific directions of the first direction and the second direction may not be limited, as long as the trigger member 320 can move from the first position to the second position.

[0103] For example, the trigger member 320 is disposed on the first joint 100. Both the first direction and the second direction can be parallel to the length direction of the first joint 100. The trigger member 320 slides on the first joint 100 so that the driving surface 3211 abuts against the driven surface 3131 and pushes the driven part 313 to move. At this time, whether the trigger member 320 is at the first position or the second position on the first joint 100 is easy to observe. The user can quickly understand the state between the first joint 100 and the second joint 200 of the current adapter assembly 10 based on the position of the trigger member 320 and whether the first joint 100 and the second joint 200 can move relative to each other, and then it is convenient for the user to judge whether it is necessary to drive the locking member 310 to lock or unlock the first joint 100 and the second joint 200 according to the current needs.

[0104] In order to enable the driving surface 3211 to drive the driven surface 3131 during the movement along the first direction, the driving surface 3211 faces the driven part 313 and the angle between the driving surface 3211 and the first direction is an acute angle. It can be understood that the width of the driving part 321 along the first direction is decreasing. When the driving surface 3211 moves along the first direction, the widest position of the driving part 321 will gradually approach the driven surface 3131 and finally abut against the driven surface 3131. During the continuous movement of the driving part 321 along the first direction, the driven surface 3131 rotates around the connecting part 311, and the locking part 312 will move away from the second joint 200.

[0105] The driving surface 3211 and the driven surface 3131 may be in surface contact. Of course, as the locking member 310 rotates, there is also line contact between the driving surface 3211 and the driven surface 3131. Compared with point contact, when the driving surface 3211 abuts against the driven surface 3131, the pressure received at the contact area between the driving surface 3211 and the driven surface 3131 is smaller, and the driving surface 3211 and the driven surface 3131 are not easily damaged due to stress. The process of the user pushing the trigger member 320 is smooth, which can improve the use feel and the user experience is good.

[0106] In addition to the cooperation between the driving surface 3211 and the bearing surface 3131, in some other embodiments, a connecting member may be provided between the driving portion 321 and the bearing portion 313. When the trigger member 320 moves along the second direction, the driving portion 321 will pull the bearing portion 313 to rotate in the opposite direction through the connecting member, and the locking portion 312 will approach the second joint 200. After the first joint 100 and the second joint 200 are rotated to a preset angle, the first joint 100 and the second joint 200 can be in a locked state.

[0107] In some embodiments, the first joint 100 is provided with a mounting member 150, and the locking member 310 is installed on the mounting member 150. When the first joint 100 and the second joint 200 remain in a locked state, the two ends of the mounting member 150 are connected or abutted against the first joint 100 and the second joint 200.

[0108] The mounting member 150 can be detachably arranged on the first joint 100 by means of a connection method such as a snap connection or a screw connection, so as to reduce the difficulty of assembling the adapter assembly 10, facilitate replacement, and reduce production and maintenance costs. When the first joint 100 and the second joint 200 remain in a locked state, the locking member 310 connects the first joint 100 and the second joint 200. When an external force acts on the first joint 100 and / or the second joint 200, the locking member 310 will also be subjected to force, thereby transmitting the force to the first joint 100 and the second joint 200 through the mounting member 150, reducing the force acting on the locking member 310, and further reducing the probability of damage to the locking member 310. The adapter assembly 10 is not easy to be damaged, and the locking member 310 will maintain a relatively accurate connection effect on the first joint 100 and the second joint 200 for a long time, and it is not easy to cause the first joint 100 and the second joint 200 to be unable to lock or unlock, thereby improving the user experience. Of course, the mounting member 150 is provided with an escape opening 151 for evading the locking member 310 , so that the locking member 310 can smoothly connect the first joint 100 and the second joint 200 .

[0109] like Figure 9 As shown, in some embodiments, when the locking member 310 is installed on the first joint 100, the switch assembly 300 also includes a reset member 330, and the reset member 330 is arranged between the locking member 310 and the first joint 100. When the trigger member 320 is in the second position, the reset member 330 can enable the locking member 310 to lock the first joint 100 and the second joint 200.

[0110] When the trigger member 320 is located at the first position, the first joint 100 and the second joint 200 are in an unlocked state. When the trigger member 320 is located at the second position, the reset member 330 provides a force to drive the locking member 310 to lock the first joint 100 and the second joint 200 . Specifically, when the trigger member 320 is located in the first position, the driving part 321 will abut against and squeeze the bearing part 313, so that the bearing part 313 is in a position close to the mounting member 150. At this time, the reset member 330 is compressed and stored under the thrust of the locking member 310; when the trigger member 320 is located in the second position, the driving part 321 and the bearing part 313 are no longer in contact or the driving part 321 and the bearing part 313 abut against each other, but the force of the driving part 321 on the bearing part 313 is less than the restoring force of the reset member 330. The reset member 330 is reset under the action of its own restoring force and pushes the locking member 310 to rotate, so that the bearing part 313 is away from the second joint 200. Under the action of the lever, the locking part 312 is engaged with the locking hole 210, so that the first joint 100 and the second joint 200 are in a locked state. It can be understood that the locking function of the locking member 310 is realized by a mechanical mechanism.

[0111] Among them, the reset member 330 can be a torsion spring, which has two torsion arms, one torsion arm is against or connected to the first joint 100, and the other torsion arm is against or connected to the locking member 310. The thickness of the torsion spring is relatively thin and the space occupied is small. The thickness of the adapter assembly 10 is reduced accordingly, thereby enabling the adapter assembly 10 to be applied to a narrower space to be cleaned.

[0112] like Figure 10 and Figure 11 As shown, in some embodiments, when the trigger member 320 is installed on the first joint 100, the first joint 100 is provided with a stopper 120, and the trigger member 320 is provided with a protrusion 323, and the stopper 120 can abut against the protrusion 323, so that the trigger member 320 is located in the first position. When the stopper 120 abuts against the protrusion 323, the stopper 120 will provide resistance to the trigger member 320, so that when there is no external force pushing the trigger member 320 along the second direction or the external force pushing the trigger member 320 is small, the trigger member 320 will remain in the first position, so that the first joint 100 and the second joint 200 are in an unlocked state. Of course, the resistance of the stopper 120 to the protrusion 323 will not be too large, so as to ensure that the trigger member 320 can move to the second position along the second direction under the action of the external force.

[0113] When an external force drives the trigger 320 to move from the first position to the second position, the protrusion 323 will squeeze the stopper 120, and the protrusion 323 and / or the stopper 120 will undergo elastic deformation under the force, so that the protrusion 323 can cross over the stopper 120. Of course, when the trigger 320 moves from the second position to the first position, the stopper 120 abuts against the protrusion 323 and provides a certain resistance, so that the trigger 320 will not easily change its position, reducing the probability that the first joint 100 and the second joint 200 are in a locked state due to accidental touch.

[0114] As Figure 11 shown, in some embodiments, when the first direction is parallel to the length direction of the first joint 100, the stopper 120 protrudes towards the trigger 320 and has a guiding surface 1201. The guiding surface 1201 can be an arc surface or an inclined surface to play a guiding role, making the process of the protrusion 323 moving from the first position to the second position or from the second position to the first position smoother, improving the user experience and being not easily damaged.

[0115] In some embodiments, the first joint 100 has a limiting groove 110, the trigger 320 is installed in the limiting groove 110, and the stopper 120 is arranged on the side wall or the bottom wall of the limiting groove 110.

[0116] It can be understood that the limiting groove 110 has a limiting effect on the trigger 320, enabling the trigger 320 to move only within the limiting groove 110 and not exceeding the first position or the second position during the movement, reducing the probability of damage to the trigger 320.

[0117] When the locking member 310 is arranged in the accommodating cavity 130, the mounting opening 140 provided on the first joint 100 is arranged on the bottom wall of the limiting groove 110. At this time, the accommodating cavity 130 is communicated with the limiting groove 110, so that the driving portion 321 of the trigger 320 installed in the limiting groove 110 can pass through the mounting opening 140 and drive the actuating portion 313 of the locking member 310.

[0118] As Figure 12 and Figure 13 shown, the stopper 120 is arranged on the side wall of the limiting groove 110. Correspondingly, the protrusion 323 of the trigger 320 can be arranged on the bottom wall or the side wall of the trigger 320, as long as the stopper 120 can abut against the protrusion 323 and the protrusion 323 can cross over the stopper 120 under the action of an external force.

[0119] As Figures 14 - 15As shown, in some embodiments, the stop portion 120 is arranged on the bottom wall of the limiting groove 110, and correspondingly, the protrusion 323 of the trigger member 320 can be arranged on the bottom wall or side wall of the trigger member 320. At this time, when the trigger member 320 is installed in the limiting groove 110, the force of the protrusion 323 on the stop portion 120 is toward the bottom wall of the limiting groove 110, the stop portion 120 is not easily damaged, and the defective rate of the adapter assembly 10 is reduced.

[0120] like Figure 16 and Figure 17 As shown, the stopper 120 can abut against the protrusion 323 , and under the action of an external force, the protrusion 323 can go over the stopper 120 , so that the trigger member 320 remains in the first position.

[0121] In some embodiments, the trigger member 320 is provided with a first guide portion 322 , and the first joint 100 is provided with a second guide portion 160 . The first guide portion 322 and the second guide portion 160 are slidably connected to enable the trigger member 320 to slide between the first position and the second position.

[0122] The sliding connection between the first guide portion 322 and the second guide portion 160 limits the moving range of the trigger member 320, so that the trigger member 320 will not exceed the first position or the second position during the movement, thereby reducing the probability of damage to the trigger member 320. For example, the first guide portion 322 may be a slider, and the second guide portion 160 may be a bar-shaped hole, and the slider may be slidably connected to the bar-shaped hole to limit the position of the trigger member 320.

[0123] Based on the same inventive concept, the embodiment of the present application also provides a cleaning device, such as Figure 18 As shown, the cleaning device includes an adapter assembly 10 .

[0124] The cleaning device generally further includes a hose 20 . The first joint 100 and the second joint 200 are both hollow tubes. The hose 20 is sleeved inside the first joint 100 and the second joint 200 to rotate with the rotation of the first joint 100 and the second joint 200 .

[0125] During the use of the cleaning device, the state of the hose 20 is restricted by the adapter assembly 10. The user sets the switch assembly 300 to the first position, and the first joint 100 and the second joint 200 remain unlocked. The cleaning device provided with the adapter assembly 10 will be able to achieve multi-form changes. The angle between the hose 20 of the cleaning device and the ground can be adapted to the user's usage method, and can cope with low-height and deep cleaning scenes such as the bottom of the sofa and the bottom of the bed; after setting the switch assembly 300 to the second position, the first joint 100 and the second joint 200 are rotated to a preset angle, so that the adapter assembly 10 can remain in a locked state. Of course, the first joint 100 and the second joint 200 can also be rotated to a preset angle, and then the switch assembly 300 is set to the second position, which can also keep the first joint 100 and the second joint 200 locked. At this time, the relative position of the hose 20 in the first joint 100 and the second joint 200 no longer changes, and the user can apply the cleaning device to a specific angle usage scenario or store the cleaning device.

[0126] Of course, the cleaning device generally also includes a main unit and a cleaning unit, which are connected by an extension rod, and the adapter assembly 10 is arranged on the extension rod so that the extension rod can be bent, and the hose 20 can be sleeved in the extension rod. When the trigger 320 is in the first position, no matter how the user drags the cleaning device and changes the relative position between the main unit and the cleaning unit, or changes the state of the extension rod, the adapter assembly 10 will not lock. Before finishing the cleaning operation of the cleaning device, the user does not need to carefully adjust the state of the relative position between the main unit and the cleaning unit to avoid the locking of the adapter assembly 10, nor does the user need to repeatedly adjust the adapter assembly 10 so that the first joint 100 and the second joint 200 are in an unlocked state. Before finishing the cleaning operation of the cleaning device, there is no need to adjust the adapter assembly 10 multiple times, and the use is less cumbersome and the user experience is good.
