Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a base structure with suction cup adsorption function and a cleaning device including the base structure. Background Technology

[0002] Currently, household appliances and storage containers are typically secured by simply contacting the outer bottom wall against a load-bearing surface. This method often results in the device tipping over due to accidental collisions, affecting usability, especially for tall or lightweight devices, thus impacting the user experience. While suction cup-based fixation devices exist, they suffer from inconvenience (requiring manual pressure to release air) or difficulty in quick separation (requiring forceful disassembly), further affecting the user experience. Utility Model Content

[0003] Therefore, it is necessary to provide a base structure and cleaning device to address the problem that household appliances or storage containers are usually simply fixed by directly contacting the outer bottom wall with the load-bearing surface during use, which often leads to the device tipping over due to accidental collisions and affecting its use.

[0004] A base structure includes: a housing assembly with a through hole at its bottom; a suction cup disposed on the outer bottom wall of the housing assembly for adhering to the installation position of the base structure, the suction cup having an adsorption cavity having an air vent communicating with the through hole; an on / off assembly including a transmission rod and a piston, at least a portion of the piston being movably disposed at the through hole to open or close the through hole and / or the air vent, the transmission rod being rotatably disposed on the housing assembly and having at least a first position and a second position, wherein when the transmission rod is in the first position, the transmission rod drives the piston to close the through hole and / or the air vent, and when the transmission rod is in the second position, the transmission rod allows the piston to open the through hole and / or the air vent; and an operating assembly movably connected to the housing assembly and the transmission rod, the operating assembly being used to lift the base structure and to switch the transmission rod between the first position and the second position.

[0005] This application provides a base structure, in which a suction cup is provided at the bottom of the housing assembly. The suction cup’s adsorption chamber can communicate with the outside through the air vent and the through hole of the housing assembly. An on / off component and an operating component are provided. The on / off component includes a transmission rod and a piston rotatably mounted on the housing assembly. The operating component is movably connected to the housing assembly and can drive the transmission rod, so that the piston can open or close the through hole and / or the air vent under the driving action of the transmission rod. Therefore, when the base structure is placed on the ground, the transmission rod will drive the piston to close the through hole and / or vent hole under the action of the operating component. Under the gravity of the housing component and other components, the suction cup is squeezed downward by the housing component, causing the air in the suction chamber to be squeezed out through the connection between the suction cup and the ground, thus forming a sealed vacuum space between the suction cup and the ground, so that the base structure can be firmly attached to the ground and avoid collision and tipping. When it is necessary to move the base structure, the user can operate the operating component to lift the base structure and drive the piston away from the through hole, so that the through hole and / or vent hole are opened. At this time, external air can enter the suction chamber of the suction cup through the through hole and vent hole, easily achieving the separation of the suction cup from the ground, which greatly facilitates the user to move and transport the base structure.

[0006] In one embodiment, the through hole is disposed opposite to the vent hole.

[0007] In one embodiment, the operating component includes a handle and a connecting rod. The handle is movably mounted on the housing assembly and is rotatable relative to the housing assembly, having at least a used state and a retracted state. One end of the connecting rod is movably connected to the handle, and the other end extends downward and is drively connected to the transmission rod. The connecting rod is configured to rise or fall relative to the housing assembly when the handle rotates, thereby driving the transmission rod to rotate. When the handle is in the retracted state, the transmission rod is in the first position; when the handle is in the used state, the transmission rod is in the second position. By adopting the above structure, the handle can be mounted on the top of the housing assembly and connected to the transmission rod via the connecting rod, thereby effectively reducing the size of the handle and the space occupied by the device. Furthermore, the use of a connecting rod drive allows for easy conversion between rotation, swing, and movement, simplifying the fit between the operating component and the transmission rod and making it easier to manufacture and maintain.

[0008] In one embodiment, a support base is formed at the bottom of the housing assembly. The support base is rotatably connected to the transmission rod and provides a fulcrum for the transmission rod. The transmission rod has a first end and a second end located on different sides of the fulcrum. The piston is configured to extend or retract relative to the through hole under the drive of the first end of the transmission rod to open or close the through hole and / or the vent hole. The second end of the transmission rod is configured to drive the transmission rod to rotate around the fulcrum under the drive of the connecting rod and switch between the first position and the second position. Compared to an assembly structure where the transmission rod is hinged to the housing assembly at its end, the lever structure described above reduces the impact of the transmission rod's own weight on the operation of the operating component, facilitates a labor-saving design for the operating component, makes the handle more sensitive to the transmission of the transmission rod, and improves the user experience.

[0009] In one embodiment, the distance between the first end of the transmission rod and the fulcrum is less than the distance between the second end of the transmission rod and the fulcrum. By employing this structure, the length of the power arm of the lever structure can be greater than the length of the resistance arm, allowing the user to control the on / off component with less force. Furthermore, when the base structure is designed to utilize the weight of the handle to stabilize it in the storage / use state, it allows manufacturers to use lightweight materials, reducing the device's weight and making it easier to carry.

[0010] In one embodiment, the first end of the transmission rod is located above the piston and the through hole. This makes the installation of the on / off assembly more convenient. Specifically, when the second end of the transmission rod is pressed down by the connecting rod, the first end of the transmission rod will rise upward, causing the piston to lose the downward force from the transmission rod. Then, driven by the first end of the transmission rod or by the elastic action of the spring, the piston will move upward away from the through hole. Thus, external air can enter the suction chamber of the suction cup through the through hole and the air vent, easily achieving the separation of the suction cup from the ground.

[0011] In one embodiment, the handle has a positioning post, and the end of the connecting rod away from the transmission rod has a groove extending along the length of the connecting rod. The positioning post is slidably inserted into the groove. When the handle rotates relative to the housing assembly, the positioning post can rotate around the rotation axis of the handle and slide against the inner wall of the groove, thereby driving the connecting rod to rise or fall relative to the housing assembly. By adopting the above structure, when the positioning post is driven by the handle to rotate around its rotation axis, the horizontal height of the positioning post will change simultaneously. Thus, the connecting rod, through its groove and sliding contact with the positioning post, can be driven to rise or fall by the positioning post, causing a change in the force applied to the transmission rod, thereby enabling the transmission rod to switch between a first position and a second position. The cooperation structure of the groove and the positioning post simplifies the assembly of the connecting rod and the handle and improves the flexibility of the connecting rod's movement trajectory, thereby reducing the machining accuracy requirements of the cooperation structure between the handle, connecting rod, and transmission rod.

[0012] In one embodiment, the handle includes a body, a pivot, and a limiting member. A first mounting hole is provided on the side wall of the housing assembly. The body is rotatably disposed on the outside of the housing assembly via the engagement of the pivot with the first mounting hole. The end of the pivot away from the body is connected to the limiting member. The side wall of the housing assembly with the first mounting hole is sandwiched between the body and the limiting member. The limiting member forms the positioning post. By using the limiting member to engage with the pivot, the handle body can be rotatably disposed on the outside of the housing assembly and securely installed. Simultaneously, the limiting member forms the positioning post for a sliding groove engagement with the connecting rod, thereby allowing the connecting rod to be positioned on the inside of the housing assembly for transmission. This reduces the possibility of collision damage and makes the base structure more aesthetically pleasing.

[0013] In one embodiment, one end of the rotating shaft is fixedly connected to one of the body and the limiting member, and the other end of the rotating shaft has a first locking portion. The other of the body and the limiting member has a second locking portion, and the first locking portion and the second locking portion are adapted to each other for installation. By fixing the rotating shaft to one of the body / limiting member and providing the first and second locking portions respectively in the rotating shaft and the other of the body / limiting member, the cooperation of the first and second locking portions facilitates the quick and easy installation of the body and the limiting member, ensuring that the limiting member can rotate synchronously around the rotating shaft as the body rotates.

[0014] In one embodiment, the body has a first connecting hole, the rotating shaft has a second connecting hole, and the limiting member has a third connecting hole. The first connecting hole, the second connecting hole, and the third connecting hole are connected to the body, the rotating shaft, and the limiting member by fasteners. By adopting the above structure, the connection strength of the body, the rotating shaft, and the limiting member can be further strengthened by using the first connecting hole, the second connecting hole, and the third connecting hole with fasteners, effectively preventing the handle from becoming loose from the housing assembly during use.

[0015] In one embodiment, the main body and the limiting member are located on opposite sides of the rotating shaft in the radial direction. When the handle rotates from the stored state to the used state, the positioning post slides against the inner wall of the groove, thereby causing the connecting rod to descend relative to the housing assembly. Specifically, by adopting the above structure, when the handle is in the used state, its main body will be vertically positioned above the housing assembly for easy lifting by the user, while the limiting member and the connecting rod will be driven to be vertically positioned at the end of the rotating shaft away from the main body. This allows the connecting rod to press down on the transmission rod under the abutment of the positioning post, while the center of gravity of the connecting rod can be lowered and aligned with the force line of the lifting force applied by the user to the main body. This makes it easier to maintain stability and reduce sway during the movement of the base structure.

[0016] In one embodiment, the end of the connecting rod away from the handle is hinged to the end of the transmission rod away from the piston. By adopting the above-mentioned hinge method, it is possible to facilitate the swinging and lifting of the connecting rod in conjunction with the rotation of the limiting member of the handle, while ensuring that the transmission rod can rotate synchronously under the lifting and lowering of the connecting rod to achieve the switching between the first position and the second position.

[0017] In one embodiment, the bottom of the housing assembly or the transmission rod is provided with a limiting part, the limiting part having a limiting hole extending along the height direction, the limiting hole being located above and opposite to the transmission rod, and the end of the connecting rod away from the handle being movably inserted into the limiting hole. By providing the limiting part, the limiting hole can limit the connecting rod, ensuring that while the handle rotates and drives the connecting rod to rise and fall relative to the housing assembly, the end of the connecting rod away from the handle remains inserted in the limiting hole and opposite to the transmission rod. This allows the connecting rod to smoothly engage with the transmission rod without requiring assembly, thus simplifying installation.

[0018] In one embodiment, the housing assembly includes an outer shell and an inner shell, the inner shell being disposed within the outer shell. The outer wall of the inner shell and the inner wall of the outer shell enclose a mounting cavity. The outer shell has a through hole communicating with the mounting cavity. At least a portion of the on / off component and / or the operating component is disposed within the mounting cavity. By adopting the above structure, an independent mounting cavity is formed between the outer shell and the inner shell for mounting the on / off component and / or the operating component. This facilitates the separation of the on / off component and connecting rods from other functional components mounted in the inner shell, thereby reducing the possibility of collision displacement of the on / off component and ensuring that the piston can be aligned and seal the through hole and / or the vent hole.

[0019] In one embodiment, the piston is mounted on the drive rod. The drive rod's transmission of the piston is achieved through a simple structure, easily moving the piston closer to or away from the through-hole.

[0020] In one embodiment, an elastic element is further included, which is disposed in the housing assembly along the height direction. The two ends of the elastic element abut against the transmission rod and the housing assembly, respectively. When the transmission rod moves from the first position to the second position, the elastic element undergoes elastic deformation and tends to return to its original shape. Due to the elastic element, when the user lifts the handle to switch from the storage state to the use state, the elastic restoring force generated by the deformation of the elastic element can drive the transmission rod to quickly move the piston away from the through hole and / or vent hole. This allows external air to enter the suction cup's suction chamber through the through hole and vent hole, easily separating the suction cup from the ground and greatly facilitating the user's movement and handling of the base structure.

[0021] A second aspect of this application provides a cleaning device.

[0022] A cleaning device includes the aforementioned base structure. The cleaning device disclosed in the second aspect of this application, by employing any of the aforementioned base structures, allows the following functionality: When the cleaning device is placed on the ground, the transmission rod, driven by the operating component, drives the piston to close the through hole and / or air passage. Under the weight of the housing assembly and cleaning module, the suction cup is compressed downwards by the housing assembly, causing air in the suction chamber to be squeezed out through the connection between the suction cup and the ground, thus forming a sealed vacuum space between the suction cup and the ground. This allows the base structure to be firmly adhered to the ground, preventing collisions and tipping. When the base structure needs to be moved, the user operates the operating component to lift the cleaning device, simultaneously moving the piston away from the through hole, opening the through hole and / or air passage. This allows external air to enter the suction chamber of the suction cup through the through hole and air passage, easily separating the suction cup from the ground and greatly facilitating the user's movement and handling of the base structure.

[0037] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0039] The base structure of some embodiments of the present invention is described below with reference to the accompanying drawings.

[0040] like Figures 1 to 7 As shown, this embodiment discloses a base structure, including: a housing assembly 1, the bottom of which has a through hole 101; a suction cup 2, which is disposed on the outer bottom wall of the housing assembly 1, and is used to adhere to the installation position of the base structure, the suction cup 2 having an adsorption cavity 201, the adsorption cavity 201 having an air passage 202 communicating with the through hole 101; and an on / off assembly 3, which includes a transmission rod 31 and a piston 32, at least a portion of which is movably disposed at the through hole 101 to open or close the through hole 101 and / or the air passage 202. The actuator 31 is rotatably mounted on the housing assembly 1 and has at least a first position and a second position. When the actuator 31 is in the first position, it drives the piston 32 to close the through hole 101 and / or the vent hole 202. When the actuator 31 is in the second position, it allows the piston 32 to open the through hole 101 and / or the vent hole 202. The operating assembly 4 is movably connected to the housing assembly 1 and the actuator 31 respectively. The operating assembly 4 is used to lift the base structure and can drive the actuator 31 to switch between the first position and the second position.

[0041] This application provides a base structure in which a suction cup 2 is provided at the bottom of the housing assembly 1. The suction chamber 201 of the suction cup 2 can be connected to the outside through the air passage 202 and the through hole 101 of the housing assembly 1. An on / off component 3 and an operating component 4 are provided. The on / off component 3 includes a transmission rod 31 and a piston 32 rotatably mounted on the housing assembly 1. The operating component 4 is movably connected to the housing assembly 1 and can drive the transmission rod 31, so that the piston 32 can open or close the through hole 101 and / or the air passage 202 under the driving action of the transmission rod 31. Therefore, when the base structure is placed on the ground, the transmission rod 31 will drive the piston 32 to close the through hole 101 and / or the air vent 202 under the action of the operating component 4. Under the gravity of the components such as the housing component 1, the suction cup 2 is squeezed downward by the housing component 1, causing the air in the suction chamber 201 to be squeezed out through the connection between the suction cup 2 and the ground, thus forming a sealed vacuum space between the suction cup 2 and the ground, so that the base structure can be firmly attached to the ground and avoid collision and tipping. When it is necessary to move the base structure, the user can operate the operating component 4 to lift the base structure and drive the piston 32 to move away from the through hole 101, so that the through hole 101 and / or the air vent 202 are opened. Thus, external air can enter the suction chamber 201 of the suction cup 2 through the through hole 101 and the air vent 202, easily separating the suction cup 2 from the ground, which greatly facilitates the user to move and transport the base structure. The suction cup (2) can be made of nitrile rubber with a thickness of 2-3mm; the elastic element (5) is preferably a compression spring with an elastic coefficient of 5-10N / mm, in order to balance the adsorption force and ease of operation.

[0042] like Figure 3 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the through hole 101 and the vent hole 202 are arranged opposite to each other.

[0043] like Figures 1 to 5As shown, in addition to the features of the above embodiments, this embodiment further defines: the operating component 4 includes a handle 41 and a connecting rod 42. The handle 41 is movably disposed on the housing component 1. The handle 41 is rotatable relative to the housing component 1 and has at least a use state and a storage state. One end of the connecting rod 42 is movably connected to the handle 41, and the other end of the connecting rod 42 extends downward and is tractively connected to the transmission rod 31. The connecting rod 42 is configured to rise or fall relative to the housing component 1 when the handle 41 rotates, so as to drive the transmission rod 31 to rotate. When the handle 41 is in the storage state, the transmission rod 31 is in a first position, and when the handle 41 is in the use state, the transmission rod 31 is in a second position. By adopting the above structure, the handle 41 can be set on the top of the housing assembly 1 and connected to the transmission rod 31 through the connecting rod 42. This can effectively reduce the size of the handle 41 and reduce the space occupied by the device. Furthermore, the use of the connecting rod 42 for transmission can easily realize the mutual conversion between rotation, swing and movement, thereby making the cooperation structure between the operating assembly 4 and the transmission rod 31 simpler and easier to manufacture and maintain.

[0044] like Figure 3 , Figure 6 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further defines: a support base 13 is formed at the bottom of the housing assembly 1, the support base 13 is rotatably connected to the transmission rod 31 and provides a fulcrum for the transmission rod 31, the transmission rod 31 has a first end 311 and a second end 312 located on different sides of the fulcrum, the piston 32 is configured to extend and retract relative to the through hole 101 under the drive of the first end 311 of the transmission rod 31 to open or close the through hole 101 and / or the vent hole 202, the second end 312 of the transmission rod 31 is configured to drive the transmission rod 31 to rotate around the fulcrum under the drive of the connecting rod 42 and switch between the first position and the second position. Compared with the assembly structure in which the transmission rod 31 is hinged to the housing assembly 1 through its end, by forming the above lever structure, the influence of the weight of the transmission rod 31 on the operation of the operating component can be reduced, and the operating component 4 can be made to achieve a labor-saving design, making the transmission of the transmission rod 31 by the handle 41 more sensitive, which is beneficial to improving the user experience.

[0045] like Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the distance between the first end 311 of the transmission rod 31 and the fulcrum is less than the distance between the second end 312 of the transmission rod 31 and the fulcrum. By adopting the above structure, the length of the power arm of the lever structure can be greater than the length of the resistance arm, so that the user can control the on / off component 3 with a smaller force. Furthermore, when the base structure is designed to use the weight of the handle 41 itself to stabilize the handle 41 in the storage / use state, it is beneficial for the manufacturer to use lightweight manufacturing materials to reduce the weight of the device and facilitate carrying.

[0046] like Figure 3 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the first end 311 of the transmission rod 31 is located above the piston 32 and the through hole 101. This makes the installation of the on / off assembly 3 more convenient. Specifically, when the second end 312 of the transmission rod 31 is pressed down by the connecting rod 42, the first end 311 of the transmission rod 31 will rise upward, causing the piston 32 to lose the downward force from the transmission rod 31. Then, driven by the first end 311 of the transmission rod 31 or by the elastic action of the spring, it will move upward away from the through hole 101. Thus, external air can enter the suction chamber 201 of the suction cup 2 through the through hole 101 and the air passage 202, easily achieving the separation of the suction cup 2 from the ground.

[0047] like Figure 2 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the handle 41 is formed with a positioning post 4131, and the end of the connecting rod 42 away from the transmission rod 31 is provided with a sliding groove 401. The sliding groove 401 extends along the length direction of the connecting rod 42, and the positioning post 4131 is slidably inserted into the sliding groove 401. When the handle 41 rotates relative to the housing assembly 1, the positioning post 4131 can rotate around the rotation axis of the handle 41 and slide against the inner wall of the sliding groove 401, thereby driving the connecting rod 42 to rise or fall relative to the housing assembly 1. By adopting the above structure, when the positioning post 4131 is driven by the handle 41 to rotate around its rotation axis, the horizontal height of the positioning post 4131 will change simultaneously. Thus, the connecting rod 42 can be driven to rise or fall by the positioning post 4131 through the sliding groove 401, causing the force applied to the transmission rod 31 to change, thereby realizing the rotational switching of the transmission rod 31 between the first position and the second position. By utilizing the mating structure of the slide groove 401 and the positioning post 4131, the assembly of the connecting rod 42 and the handle 41 can be made simpler, and the flexibility of the moving trajectory of the connecting rod 42 can be improved. This helps to reduce the machining accuracy requirements of the mating structure between the handle 41, the connecting rod 42 and the transmission rod 31.

[0048] like Figure 6 and Figure 7As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the handle 41 includes a body 411, a rotating shaft 412, and a limiting member 413. The side wall of the housing assembly 1 is provided with a first mounting hole. The body 411 is rotatably disposed on the outside of the housing assembly 1 through the cooperation of the rotating shaft 412 with the first mounting hole. The end of the rotating shaft 412 away from the body 411 is connected to the limiting member 413. The side wall of the housing assembly 1 with the first mounting hole is sandwiched between the body 411 and the limiting member 413. The limiting member 413 forms a positioning post 4131. By using the limiting member 413 to cooperate with the rotating shaft 412, the handle 41 body 411 can be rotatably disposed on the outside of the housing assembly 1 and securely installed. At the same time, the limiting member 413 forms a positioning post 4131 for the sliding groove 401 of the connecting rod 42 to cooperate with it. Thus, the connecting rod 42 will be disposed on the inside of the housing assembly 1 for transmission, which can reduce the possibility of collision damage and make the appearance of the base structure simpler and more beautiful.

[0049] In addition to the features of the above embodiments, this embodiment further specifies that: one end of the rotating shaft 412 is fixedly connected to one of the body 411 and the limiting member 413, the other end of the rotating shaft 412 forms a first locking portion, and the other of the body 411 and the limiting member 413 forms a second locking portion, the first locking portion and the second locking portion being adapted for installation. By fixing the rotating shaft 412 to one of the body 411 / limiting member 413, and respectively providing the first locking portion and the second locking portion adapted for installation in the other of the rotating shaft 412 and the body 411 / limiting member 413, the cooperation of the first locking portion and the second locking portion facilitates the quick and easy installation of the body 411 and the limiting member 413, ensuring that the limiting member 413 can rotate synchronously around the rotating shaft 412 with the rotation of the body 411.

[0050] In addition to the features of the above embodiments, this embodiment further specifies that: the body 411 is provided with a first connecting hole, the rotating shaft 412 is provided with a second connecting hole, and the limiting member 413 is provided with a third connecting hole. The first connecting hole, the second connecting hole, and the third connecting hole are connected to the body 411, the rotating shaft 412, and the limiting member 413 by fasteners. By adopting the above structure, the connection strength of the body 411, the rotating shaft 412, and the limiting member 413 can be further strengthened by using the first connecting hole, the second connecting hole, and the third connecting hole with fasteners, effectively preventing the handle 41 from becoming loose from the housing assembly 1 during use.

[0051] like Figure 2 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the body 411 and the limiting member 413 are respectively located on opposite sides of the rotating shaft 412 in the radial direction. When the handle 41 rotates to switch from the storage state to the use state, the positioning post 4131 slides against the inner wall of the slide groove 401 to drive the connecting rod 42 to descend relative to the housing assembly 1. Specifically, by adopting the above structure, when the handle 41 is in the use state, its body 411 will be arranged vertically above the housing assembly 1 for easy lifting by the user, while the limiting member 413 and the connecting rod 42 will be driven to be arranged vertically at the end of the rotating shaft 412 away from the body 411. This allows the connecting rod 42 to press down on the transmission rod 31 under the abutment of the positioning post 4131, while the center of gravity of the connecting rod 42 can be lowered and aligned with the force line of the lifting force applied by the user to the body 411. This makes it easier to maintain stability and reduce swaying during the movement of the base structure.

[0052] In addition to the features of the above embodiments, this embodiment further specifies that the end of the connecting rod 42 away from the handle 41 is hinged to the end of the transmission rod 31 away from the piston 32. By adopting the above hinge method, it is possible to facilitate the swinging and lifting of the connecting rod 42 in conjunction with the rotation of the limiting member 413 of the handle 41, while ensuring that the transmission rod 31 can rotate synchronously under the lifting and lowering drive of the connecting rod 42 to achieve its switching between the first position and the second position.

[0053] like Figure 6 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the bottom of the housing assembly 1 or the transmission rod 31 is provided with a limiting part 14, the limiting part 14 is provided with a limiting hole 102 extending along the height direction, the limiting hole 102 is located above the transmission rod 31 and opposite to the transmission rod 31, and the end of the connecting rod 42 away from the handle 41 is movably inserted into the limiting hole 102. By setting the limiting part 14, the limiting hole 102 can limit the connecting rod 42, ensuring that while the handle 41 rotates and drives the connecting rod 42 to rise and fall relative to the housing assembly 1, the end of the connecting rod 42 away from the handle 41 can always be inserted into the limiting hole 102 and remain opposite to the transmission rod 31, so that the connection with the transmission rod 31 can smoothly engage with the transmission rod 31 without assembly connection, specifically, this simplifies the installation work.

[0054] like Figure 2 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further defines: the housing assembly 1 includes an outer shell 11 and an inner shell 12, the inner shell 12 is disposed in the outer shell 11, the outer wall of the inner shell 12 and the inner wall of the outer shell 11 enclose to form a mounting cavity 103, the outer shell 11 is provided with a through hole 101 communicating with the mounting cavity 103, and at least a portion of the switching component 3 and / or the operating component 4 is disposed in the mounting cavity 103. By adopting the above structure, an independent mounting cavity 103 is formed between the outer shell 11 and the inner shell 12 for installing the switching component 3 and / or the operating component 4, which can facilitate the separation of the switching component 3 and the connecting rod 42 from other functional components installed in the inner shell 12, thereby reducing the possibility of collision displacement of the switching component 3 and ensuring that the piston 32 can be aligned and seal the through hole 101 and / or the vent hole 202.

[0055] like Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the piston 32 is mounted on the transmission rod 31. The transmission rod 31 can drive the piston 32 through a simple structure, easily moving the piston 32 closer to or further away from the through hole 101.

[0056] like Figure 6 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further includes an elastic element 5, which is disposed in the housing assembly 1 along the height direction. The two ends of the elastic element 5 abut against the transmission rod 31 and the housing assembly 1, respectively. When the transmission rod 31 moves from the first position to the second position, the elastic element 5 undergoes elastic deformation and tends to return to its original shape. Through the elastic element 5, when the user lifts the handle 41 to switch from the storage state to the use state, the elastic restoring force generated by the deformation of the elastic element 5 can drive the transmission rod 31 to move the piston 32 quickly away from the through hole 101 and / or the vent hole 202. This allows external air to enter the suction chamber 201 of the suction cup 2 through the through hole 101 and the vent hole 202, easily separating the suction cup 2 from the ground and greatly facilitating the user's movement and handling of the base structure.

[0057] A second aspect of this application provides a cleaning device.

[0058] A cleaning device includes the aforementioned base structure. The cleaning device provided in the second aspect of this application, by adopting the base structure of any of the aforementioned, when the cleaning device is placed on the ground for use, the transmission rod 31 will drive the piston 32 to close the through hole 101 and / or the air passage 202 under the drive of the operating component 4. Under the gravity of the housing component 1 and the cleaning module and other components, the suction cup 2 is squeezed downward by the housing component 1, causing the air in the suction chamber 201 to be squeezed out through the connection between the suction cup 2 and the ground, thereby forming a sealed vacuum space between the suction cup 2 and the ground, so that the base structure can be firmly adsorbed on the ground, avoiding collision and tipping. When it is necessary to move the base structure, the user can operate the operating component 4 to lift the cleaning device and drive the piston 32 to move away from the through hole 101, thereby opening the through hole 101 and / or the air passage 202. As a result, external air can enter the suction chamber 201 of the suction cup 2 through the through hole 101 and the air passage 202, easily achieving the separation of the suction cup 2 from the ground, greatly facilitating the user to move and transport the base structure.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
