Description

Technical Field

[0001] This utility model relates to the field of cleaning tool technology, and in particular to a mop bucket and its cleaning components. Background Technology

[0002] A mop bucket is a common cleaning tool in daily life. Used in conjunction with a mop, it's a container for washing and wringing out the mop. With the continuous development of electronic technology, some mop buckets have begun to integrate an electrically driven motor (hereinafter referred to as an electric mop bucket). These electric mop buckets are powered by an electric motor, and users can control the motor to wash and wring out the mop simply by operating buttons or pedals.

[0003] Since motorized mop buckets typically rotate the mop during washing or wringing, users are usually required to hold the mop during this process to ensure it remains securely within the bucket and prevent it from wobbling or slipping out.

[0004] However, this additional mop-holding operation is not welcomed by users and has a negative impact on the actual user experience of electric mops. Utility Model Content

[0005] The mop bucket and cleaning components provided by this utility model can overcome the shortcomings of existing electric mop buckets, which require the user to hold the mop when washing and wringing it.

[0006] In a first aspect, this utility model provides a mop bucket. The mop bucket includes: a mop bucket body, the interior of which forms a cavity with an open top; an inner bucket, rotatably disposed within the cavity of the mop bucket body, dividing the cavity into a washing space for accommodating a mop and a water storage space; a driving device, disposed within the mop bucket body and pulsatorically connected to the inner bucket, the driving device driving the inner bucket to rotate around the bucket body axis; and a mop bucket handle, spanning the open top of the mop bucket body and rotatably connected to the mop bucket body; wherein the mop bucket handle is provided with a limiting groove adapted to the mop, so that the mop bucket handle engages with the mop inserted into the washing space.

[0007] Secondly, this utility model embodiment also provides a cleaning component. The cleaning component includes: a mop bucket and a mop as described above; wherein, when the mop is inserted into the cleaning space, the mop bucket handle, which is rotated to a preset limit position, engages with the mop.

[0008] At least one advantage of the mop bucket provided by this utility model is that by providing a limiting groove on the mop bucket handle that is adapted to the mop, the mop bucket handle can be engaged with the mop inserted into the washing space, thereby reliably positioning the mop in the mop bucket and preventing the mop from shaking or being thrown out due to centrifugal force during the rotation washing or spin-drying process. This structural design eliminates the need for the user to hold the mop during washing or spin-drying, reducing the user's operational burden. Attached Figure Description

Detailed Implementation

[0012] The present application will now be described in detail with reference to specific embodiments. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope and application of the present application.

[0013] It should be noted that, unless otherwise expressly specified and limited, the terms "center," "longitudinal," "lateral," "upper," "lower," "vertical," "horizontal," "inner," and "outer," etc., used in this specification to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. The terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0014] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features; thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. "Several" means one or more, and "multiple" means two or more; "and / or" includes any and all combinations of one or more of the associated listed items. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0015] Figure 1 This is a schematic diagram of a mop bucket provided in an embodiment of this application. Figure 2 for Figure 1 The diagram shows a cross-sectional view of the mop bucket along the AA direction. Figure 1 and Figure 2 As shown, the mop bucket 1 includes: a mop bucket body 10, an inner bucket 20, a drive device 30, a trigger pedal 40, and a control device 50.

[0016] The mop body 10 is the main structure of the entire mop 1. Its specific size and shape can be chosen to suit any appropriate needs. For example, Figure 1 The image shows a generally cylindrical mop body. Alternatively, the mop body could also be an elliptical cylinder or other three-dimensional structure.

[0017] The mop body 10 is a container with an open top. It has an internal cavity K1 for holding water. Specifically, for electrical waterproofing requirements, please refer to [further details]. Figure 2 The tub body 10 also has an isolation structure 11 inside. The isolation structure 11 forms an isolated equipment receiving cavity K2 in the cavity K1, providing a waterproof area for the installation and housing of some electrical-related functional modules that have waterproof requirements and cannot come into contact with liquids.

[0018] The inner tub 20 is a container slightly smaller in size than the cavity K1. It is rotatably disposed within the cavity K1 formed by the tub body 10, thereby dividing the cavity K1 into two relatively independent spaces.

[0019] In this embodiment, as Figure 2 As shown, the space enclosed by the inner tub 20 is used to accommodate the mop and is called the "cleaning space K11", while the space formed by the gap between the outer surface of the inner tub 20 and the mop body 10 is called the "water storage space K12".

[0020] Ideally, please continue reading. Figure 2 The inner tub 20 may have a step 27 inside. The step 27 forms a recessed area K14 at the bottom of the cleaning space K11 for accommodating the cleaning strip of the mop.

[0021] The recessed area K14 allows the mop's cleaning strips 203 to move relatively freely and remain unfolded during the rotation of the inner tub, preventing them from being compressed by the inner wall of the inner tub 20, thus improving the cleaning and wringing effect.

[0022] Specifically, such as Figure 4 As shown, the inner tub 20 includes: a tub bottom 21 and an inner tub side wall 22.

[0023] The bucket bottom 21 is a closed bottom. It is detachably assembled inside the bucket body 10 and is connected to the drive unit 30 via transmission.

[0024] The inner tub sidewall 22 is a continuous wall structure extending from the edge of the tub bottom 21 along the tub axis x1 for a predetermined inner tub height. Together with the tub bottom 21, it encloses the aforementioned cleaning space K11.

[0025] Preferably, a locking structure 23 can also be provided on the side of the bottom 21 away from the drive device 30. The locking structure 23 is used to engage with the mop 2 inserted in the cleaning space so that the mop head 202 of the mop 2 can be fixed in the cleaning space K11, preventing the mop from colliding with the inner tub when the inner tub 20 rotates.

[0026] The drive unit 30 is a power device used to output torque and drive the inner tub 20 to rotate. It is installed inside the tub body 10 and is connected to the inner tub 20 installed in the cavity K1.

[0027] For details, please continue reading. Figure 2 The drive device 30 includes a drive motor 31 and a transmission assembly 32.

[0028] The drive motor 31 is a drive device that converts electrical energy into mechanical energy and outputs rotational motion through the motor output shaft. As an electrical device, it is housed and fixed within the equipment housing cavity K2.

[0029] The transmission assembly 32 is a structural component that forms the power transmission path between the drive motor 31 and the inner tub 20. It passes through the isolation structure 11 via a sealing member, and its two ends are connected to the drive motor 31 and the inner tub 20 respectively, thereby realizing the power transmission from the drive motor 31 to the inner tub 20.

[0030] Depending on the specific application requirements, the sealing component can be any suitable type of structural component (e.g., a sealed rolling bearing), as long as it can ensure the watertightness of the isolation structure 11 and prevent liquid from entering the equipment housing cavity K2.

[0031] The trigger pedal 40 is an interactive device used to collect user interaction operations. When the user applies external force to the trigger pedal 40 by stepping or pressing, it generates a pedal signal in the form of an electrical signal, allowing the user's interaction operation to be sensed by the control device of the mop. This pedal signal can be any suitable type of electrical signal (e.g., a specific high-level signal), and is not specifically limited herein.

[0032] Specifically, at least a portion of the trigger pedal 40 is located outside the mop body 10, near the bottom of the mop body 10, so that the user can interact by stepping on it.

[0033] It is understandable that, based on the actual needs, any other suitable form of interactive device may be adopted, not limited to the pedal form shown in the accompanying drawings.

[0034] The control device 50 is the main control core of the entire tub. As an electrical device, it is also housed within the equipment housing cavity K2 of the tub body 10. Figure 16 As shown, the control device 50 can be electrically connected to the trigger pedal 40 and the drive device 30 respectively by means of connecting wires or the like.

[0035] Specifically, such as Figure 3 As shown, the control device 50 includes a circuit board 51 and a rechargeable battery 52.

[0036] The circuit board 51 is a board-shaped structure integrating control circuitry. It can accommodate multiple electronic components required by the control circuitry and provide electrical connections between these components, depending on the specific needs of the application. Technicians can choose to use any suitable type of control circuitry based on the actual requirements; no specific limitations are imposed here.

[0037] The rechargeable battery 52 is a device for storing electrical energy (e.g., a lithium-ion battery or a lithium iron phosphate battery). It is electrically connected to the control circuitry integrated on the circuit board 51, serving as the power supply for the trolley 1 and for powering the aforementioned drive motor 31 and other electrical equipment.

[0038] Preferably, the control device 50 may further include a charging port 53 and a switch 54 disposed on the outer surface of the mop body 10. The charging port 53 is used to connect to an external power source for charging the rechargeable battery 52. ​​The switch 54 is an interactive device for controlling the power supply on and off. The user can control the rechargeable battery 52 to supply power or stop power by pressing the switch 54, thereby switching the control device 50 between an operating state and an off state.

[0039] Specifically, the switch 54 can be any suitable type of input device used to convert user interaction operations into corresponding switch control signals to enable user interaction. Examples include mechanical push-button switches, touch switches, capacitive inductive switches, infrared inductive switches, pressure-sensitive switches, and toggle switches.

[0040] The generated switch control signal instructs the control device 50 to switch states. That is, when the control device 50 is in the off state, it will be turned on upon receiving the switch control signal, switching back to the running state. Conversely, when the control device 50 is in the running state, it will stop supplying power and switch back to the off state upon receiving the switch control signal.

[0041] By incorporating a rechargeable battery 52 within the mop body 10, the ease of use of the mop can be improved. The mop can be used in any position without being restricted by an external power supply cable. Furthermore, the control device, which is entirely encapsulated within the device housing K2, also enhances waterproof performance, preventing safety accidents such as electric leakage caused by the external power supply cable being immersed in liquid.

[0042] In this embodiment, the control device 50 detects the pedal signal fed back by the trigger pedal 40 and controls the operation of the drive device 30 according to whether the preset trigger conditions are met, so as to complete a specific operation task.

[0043] In some embodiments, the control device 50 controls the drive device 30 to perform a spin-drying operation each time the first trigger condition is detected.

[0044] The first triggering condition includes receiving a pedal signal. In other words, when the control device 50 detects that the trigger pedal has been pressed, it generates a corresponding control signal to control the drive device 30 to perform a spin-drying operation.

[0045] The "spin-drying operation" refers to the process of removing water from the mop 2 inserted in the cleaning space, reducing the amount of water remaining in the mop. This can be achieved in various ways. In this embodiment, the spin-drying operation utilizes centrifugal force, driving the inner tub 20 to rotate at a preset first speed for a preset first time, so that the water in the cleaning space K11 enters the water storage space K12 under the action of centrifugal force.

[0046] For details on the specific implementation of the spin-drying operation described above, please refer to [link / reference needed]. Figure 4 The inner tub 20 has several drain outlets 25 and elastic sealing components 24 for sealing the drain outlets 25.

[0047] The elastic sealing component 24 is a sealing member with elastic deformation capability. In the initial state where no external force is applied or the external force is insufficient to overcome the elastic force, it is tightly attached to the inner tub 20 to block the corresponding drain outlet 25. However, when subjected to a sufficiently strong external force, it will undergo elastic deformation, moving away from the inner tub 20 and thus opening the corresponding drain outlet 25.

[0048] Therefore, when the drive device 30 drives the inner tub 20 to rotate at a preset first speed around the tub axis x1, it can generate sufficient external force to cause the elastic sealing component 24 to undergo elastic deformation, open the drain outlet 25, and realize the spin-drying function.

[0049] In this application, "corresponding" refers to the matching relationship between the elastic sealing component 24 and the drain outlet 25. For example, one elastic sealing component 24 can be paired with one drain outlet 25 to block or open the paired drain outlet 25 respectively, or one elastic sealing component 24 can also be configured to correspond to two or more drain outlets 25 at the same time to block or open multiple corresponding drain outlets simultaneously.

[0050] The specific matching relationship between the elastic sealing component 24 and the drain outlet 25 can be selected or appropriate structural settings can be used according to actual needs, and no specific limitations are made here.

[0051] Preferably, a plurality of drain outlets 25 are evenly arranged along the circumference of the inner barrel sidewall 22 and are located close to the barrel bottom 21. In other words, the distance between the drain outlet 25 and the barrel bottom 21 is less than the distance between the drain outlet and the top of the inner barrel sidewall 22, and the drain outlet 25 is closer to the barrel bottom 21.

[0052] This placement of the drain outlet 25, positioned as low as possible, helps ensure that water in the cleaning space is reliably drained, thus ensuring the mop's spin-drying effect.

[0053] Specifically, this "close position" can also be defined by whether the distance on the bucket axis x1 meets a preset value. In other words, when the distance between the drain outlet 25 and the bottom of the bucket 21 is less than the preset value, it indicates that they are in a close position.

[0054] This preset value is a permissible error value pre-set based on actual application requirements and structural design limitations, and is not specifically limited here. For example, it can be determined based on factors such as the drain outlet diameter and the bottom thickness of the tank.

[0055] In other embodiments, when the mop also has an automatic cleaning function, the control device 50 is further configured to: control the drive device to sequentially perform a cleaning operation and a spin-drying operation each time a first trigger condition is detected.

[0056] The "cleaning operation" refers to the process of cleaning the mop 2 inserted in the cleaning space with water to reduce the contaminants it carries. In this embodiment, the cleaning operation can be achieved by rotating the inner tub 20 in a preset pattern, using inertial force to make the water in the cleaning space rinse the mop.

[0057] Specifically, the preset mode includes: the inner tub rotating at a preset second speed for a preset second time. This second speed is a rotational speed significantly lower than the first speed during the spin-drying operation. For example, the second speed is 10% or 20% of the first speed. This relatively low speed ensures that the water in the washing space rinses the mop without causing elastic deformation of the elastic sealing component 24, thus ensuring that the drain outlet 25 is blocked during the washing operation.

[0058] Alternatively, the preset mode may also include: the inner tub rotating alternately a preset number of times. "Alternating rotation" refers to the regular alternation of forward and reverse rotations, consisting of several alternating forward and reverse rotations. Each forward or reverse rotation represents one complete rotation of the inner tub in the corresponding direction.

[0059] "Forward rotation" and "reverse rotation" are relative concepts, corresponding to two opposite directions of rotation of the inner tub. The specific number of forward and reverse rotations is not limited here and can be set according to actual needs.

[0060] Preferably, the inner bucket 20 can also be equipped with additional brush heads or similar cleaning components. The mop is cleaned by the relative movement between these cleaning components and the mop inserted into the cleaning space, thereby improving the cleaning effect of the mop.

[0061] In some embodiments, "cleaning operation" may also refer to soaking a mop inserted in the cleaning space K11 for a preset period of time.

[0062] In some embodiments, please continue reading Figure 4 The resilient sealing assembly 24 includes a spring 241 and a sealing element 242.

[0063] The spring piece 241 is a long, strip-shaped elastic element. Its two ends, which are far apart from each other along its length, are referred to as the "first end" and the "second end," respectively. The first end of the spring piece 241 is connected to the outer surface of the inner barrel side wall 22.

[0064] The sealing component 242 is a part used to seal the drain outlet 25. It is fixed to the second end of the spring piece 241, and under the elastic force of the spring piece 241, it is tightly attached to the outer surface of the inner barrel side wall, thereby sealing the drain outlet 25.

[0065] Ideally, for even better sealing, please refer to [link / reference needed]. Figure 4 An inclined annular arc surface 243 may be provided on the outer surface of the inner barrel sidewall, surrounding the outer periphery of the drain outlet. The sealing member 242 is provided with a spherical outer surface adapted to the annular arc surface. When the sealing member 242 is in close contact with the outer surface of the inner barrel sidewall, the spherical outer surface is in contact with the annular arc surface 243.

[0066] This surface contact between the spherical outer surface and the annular arc surface achieves a tighter and more uniform fit, effectively improving sealing performance. Furthermore, the inclined annular arc surface structure guides the sealing element 242 to automatically align during repositioning, providing a degree of self-correction and further enhancing the stability and reliability of the seal.

[0067] In other embodiments, the sealing element 242 in the resilient sealing assembly 24 can be omitted, and the drain outlet 25 can be sealed directly through the second end of the spring piece 241.

[0068] In practical applications, such as Figure 5 As shown, as the inner tub 20 rotates at a high speed in the direction indicated by the arrow, the spring piece 241 will undergo elastic deformation due to a strong external force. Correspondingly, the deformation of the spring piece 241 causes the sealing member 242 to move away from the side wall of the inner tub. At this time, the drain outlet 25 is opened, and water can flow through the drain outlet 25 into the water storage space K12.

[0069] Conversely, when the inner tub 20 rotates at a low speed or not at all, the spring 241 will remain in its initial state, pressing the sealing member 242 tightly against the outer surface of the inner tub side wall, blocking the drain outlet 25, so that the water in the cleaning space K11 will not flow out.

[0070] It is understandable that the rotation direction of the inner tub 20 is related to the installation and fixing method of the spring piece 241. The relative positional relationship between the first end of the spring piece 241 fixed to the side wall 22 of the inner tub and the second end whose position changes due to the elastic deformation of the spring piece determines the rotation direction of the inner tub 20.

[0071] Specifically, to ensure that the second end of the spring is subjected to a centrifugal force away from the inner tub when the inner tub 20 rotates, the second end of the spring is located behind the first end of the spring in the direction of rotation of the inner tub. In other words, starting from any point outside the arc length corresponding to the spring, along the direction of rotation of the inner tub, the spring will first pass through the second end and then through the first end.

[0072] As previously described, during the cleaning and spin-drying operations, the drive unit drives the inner drum 20 to rotate about the axial direction at two significantly different rotational speeds. In some embodiments, the drive unit 30 may be a power unit with multiple different output modes, used to meet the different inner drum rotational speeds required for the aforementioned cleaning and spin-drying operations.

[0073] For example, the drive device 30 has two output modes: a first output mode and a second output mode. The first output mode is an output mode with a faster rotation speed, driving the inner tub to rotate at a first speed, while the second output mode is an output mode with a larger output torque, driving the inner tub to rotate at a slower second speed.

[0074] In some embodiments, the drive device 30 can switch between various output modes by changing the output power or operating state of the drive motor 31.

[0075] In other embodiments, the drive device 30 with multiple different output modes is implemented using a transmission assembly 32 with different gear ratios. The transmission assembly 32 can switch between multiple gear ratios, thereby enabling the drive device 30 to operate in different output modes.

[0076] In other words, each gear of the transmission assembly 32 corresponds to an output mode. For example, the transmission assembly 32 may have a high-speed gear with a large transmission ratio and low-speed gears with a small transmission ratio, corresponding to the first output mode and the second output mode of the drive device 30, respectively.

[0077] To further simplify operation and control, in some embodiments, the drive device 30 has an automatic output mode switching function. Each time it receives a trigger command, it runs sequentially in various output modes until each output mode has been run once, after which it stops running. In other words, the drive device 30 automatically executes all of its output modes once according to a preset switching order and running time.

[0078] The switching order between various output modes and the runtime of each output mode are preset according to actual needs and are not specifically limited here. For example, each time a trigger command is received, the drive device 30 first runs in the second output mode for a preset second time to complete a washing operation. Then, it switches to the first output mode and runs for a preset first time to complete a spin-drying operation.

[0079] By using a drive device 30 that automatically switches output modes, the user's operation process can be effectively simplified. The user only needs to issue an output trigger command, and the drive device 30 can automatically switch output modes sequentially according to a preset order and running time, avoiding the problems of manual switching and repetitive operations.

[0080] To fully describe the inventive concept of this application, the specific implementation of the transmission component with different gears is described in detail below with reference to the accompanying drawings.

[0081] like Figure 6 and Figure 9 As shown, the transmission assembly 32 includes: a transmission mechanism housing 321, multiple transmission components 322, a power output shaft 323, and an automatic shifting mechanism 324.

[0082] The transmission mechanism housing 321 is an outer shell that provides installation space and structural support. It extends approximately along the transmission axis x2, with a power output shaft 323 extending from one end of the transmission axis x2, and the other end connected to the motor output shaft of the drive motor 31 as a power input end.

[0083] Multiple transmission components 322 are assembled and housed inside the transmission mechanism housing 321. These transmission components 322 form a multi-stage planetary gear set connected in series to complete the power transmission between the drive motor 31 and the power output shaft 323.

[0084] The power output shaft 323 is the power output end of the transmission assembly and is connected to the load. The first end of the power output shaft 323 is connected to the last stage planetary gear in the multi-stage planetary gear set, and the second end, which is away from the first end, extends to the water storage space K12 and is connected to the inner tank 20.

[0085] Specifically, a snap-fit ​​element 325 may also be provided at the second end of the power output shaft 323. Please refer to the following: Figure 5 The bottom of the inner tub 20 is provided with a recess 26 that is compatible with the snap-fit ​​component 325. After the snap-fit ​​component 325 is inserted into the recess 26 at the bottom of the inner tub 20, a detachable snap-fit ​​connection is formed between the transmission component and the inner tub.

[0086] This locking connection enables axial positioning and power transmission, allowing the inner tub 20 to rotate with the power output shaft 323. Depending on the specific application requirements, the locking component 325 can be a radial protrusion, a raised block, a slot structure, or other limiting components capable of achieving a locking connection; no specific limitations are specified here.

[0087] The automatic shift mechanism 324 is a device used to control and switch the gears of the transmission assembly 32. It is fixed outside the transmission mechanism housing 321 and achieves gear switching of the transmission assembly 32 by changing the relative position or operating state of some transmission components 322.

[0088] In this embodiment, one stage of the multi-stage planetary gear set is configured as a planetary gear set with a variable transmission ratio. The ring gear of this stage of the variable transmission ratio planetary gear set is a shift ring gear 3221 that can switch between locked and unlocked states.

[0089] When the shift ring gear 3221 is locked and cannot rotate, the planet carrier and sun gear of this stage of the planetary gear set have a first transmission ratio. When the shift ring gear 3221 is unlocked and can rotate with the planet gears, the transmission path of the planetary gear set changes, and the planet carrier and sun gear have a second transmission ratio.

[0090] The automatic shift mechanism 324 is connected to the shift ring gear 3221 and is used to control the shift ring gear 3221 to switch between locked and unlocked states, thereby switching the planetary gear set between the first transmission ratio and the second transmission ratio, and thus controlling the gear position of the transmission component 32.

[0091] Alternatively, the automatic shift mechanism 324 can be replaced with other suitable types of mechanical shift mechanisms. These mechanisms, through manually operable components (e.g., levers, knobs, or sliders) extending outside the hopper body, allow the user to lock or release the shift gear ring by applying external force, thereby controlling the gear position of the transmission assembly 32.

[0092] For example, Figure 7 and Figure 8 The diagram shows a configuration of multiple transmission components 322 forming a three-stage planetary gear set (labeled as first-stage planetary gear set 322a, second-stage planetary gear set 322b, and third-stage planetary gear set 322c, respectively).

[0093] In this transmission assembly, the sun gear of the first-stage planetary gear set 322a is connected to the output shaft of the drive motor 31, serving as the power input end. The planet carrier of the first-stage planetary gear set 322a is connected to the sun gear of the second-stage planetary gear set 322b, further transmitting power to the second-stage planetary gear set 322b.

[0094] The second-stage planetary gear set 322b is configured as a planetary gear set with a variable transmission ratio. The ring gear of this new gear set is a shift ring gear 3221. When the shift ring gear 3221 is in the locked state, the sun gear of the second-stage planetary gear set 322b transmits power to the planet carrier of the second-stage planetary gear set 322b according to a first transmission ratio. When the shift ring gear 3221 is in the unlocked state, the sun gear of the second-stage planetary gear set 322b transmits power to the planet carrier of the second-stage planetary gear set 322b according to a second transmission ratio.

[0095] The planet carrier of the second-stage planetary gear set 322b is connected to the sun gear of the third-stage planetary gear set 322c, further transmitting power to the third-stage planetary gear set 322c. The planet carrier of the third-stage planetary gear set 322c is connected to the first end of the power output shaft 323, thereby driving the power output shaft 323 to rotate.

[0096] In some embodiments, the switching between the locked and unlocked states of the shift gear ring 3221 can be achieved by changing the relative position of the shift gear ring 3221 within the transmission mechanism housing 321.

[0097] like Figure 7 and Figure 8 As shown, a series of locking protrusions 326 are provided inside the transmission mechanism housing 321. These locking protrusions 326 are arranged in a circumferential direction.

[0098] Correspondingly, the shift ring 3221 has a degree of freedom of movement on the drive axis x2 and is provided with recesses 327 that are adapted to the locking protrusions 326. These recesses 327 are also arranged around the circumference of the shift ring 3221 and are located on the side surface of the shift ring 3221 facing the locking protrusions 326.

[0099] In the actual state transition process, such as Figure 7 As shown, when the shift gear ring 3221 moves along the transmission axis x2 to the locking position where the recess 327 of the shift gear ring engages with the locking protrusion 326, the shift gear ring 3221 is restricted by the locking protrusion 326 and cannot rotate freely, thus being in a locked state.

[0100] like Figure 8 As shown, when the shift ring 3221 moves in the opposite direction along the transmission axis x2 and the recess 327 of the shift ring is disengaged from the locking protrusion 326, the shift ring 3221 will not be affected by the shift ring 3221 and can rotate freely with the planetary gear to switch to the unlocked state.

[0101] In some embodiments, please continue reading Figure 6 The automatic gear shifting mechanism 324 includes: a gear shifting motor 3241 and a gear ring actuation structure 3242.

[0102] The gear shifting motor 3241 is connected to the shift gear ring 3221 via the gear ring actuation structure 3242. Powered by the gear shifting motor 3241, the gear ring actuation structure 3242 converts the rotational motion output by the gear shifting motor 3241 into linear motion of the shift gear ring 3221, thereby driving the shift gear ring 3221 to move between a locked position and a free position along the transmission axis x2.

[0103] Specifically, such as Figure 9 As shown, the gear ring actuation structure 3242 for realizing the conversion between rotary motion and linear motion includes: a shift paddle 3242a and a shifting component 3242b. Correspondingly, the outer peripheral surface of the shift gear ring 3221 is provided with an annular groove 3222 extending in the circumferential direction, and the transmission mechanism housing 321 is provided with a through groove 3211 extending in the direction of the transmission axis.

[0104] The shift paddle 3242a is sleeved on the outside of the transmission mechanism housing 321 and can rotate relative to the transmission mechanism housing 321 between a preset first position and a second position.

[0105] In this embodiment, "first position" and "second position" refer to the positions of the shift paddles when the transmission assembly is in the first gear and the second gear, respectively. In other words, when the shift paddle 3242a is in the first position, the shift gear ring 3221 is in the locked position, and when the shift paddle 3242a is in the second position, the shift gear ring is in the free position.

[0106] For example, the shift paddle 3242a is generally arc-shaped. It cooperates with the cylindrical surface of the transmission mechanism housing 321 and can rotate between a first position and a second position along a set trajectory under the action of the guide mechanism.

[0107] Alternatively, other suitable shapes or structures of shift paddles 3242a can be used, as long as they can form a rotation guide mechanism to ensure that the shift paddles 3242a can rotate stably along the set trajectory.

[0108] In some embodiments, the gear shifting motor 3241 can drive the shift paddles via toothed engagement. For example, as... Figure 9 As shown, a shift gear A1 is provided on the output shaft of the gear shifting motor 3241, and a shift rack A2 of a preset length is correspondingly provided on the surface of the shift paddle 3242a. Thus, by meshing the shift gear A1 and the shift rack A2, the gear shifting motor 3241 can drive the shift paddle 3242a to rotate between a preset first position and a preset second position.

[0109] The actuating component 3242b is an arc-shaped component fitted within the annular groove 3222 of the shift ring 3221. It also has a protrusion 3242c that protrudes from the transmission mechanism housing via a through groove 3211.

[0110] Please continue reading. Figure 9 The shift paddle 3242a has a guide groove 3242d. The guide groove 3242d has a first groove end and a second groove end that are spaced at a preset distance on the drive shaft, and a connecting portion that connects the first groove end and the second groove end.

[0111] The protrusion 3242c, which protrudes from the transmission mechanism housing 321, is fitted into the guide groove 3242d. As the shift paddle 3242a rotates, the protrusion 3242c also moves along the guide groove 3242d between the end of the first groove and the end of the second groove, realizing the conversion between rotational and linear motion.

[0112] Furthermore, as the protrusion 3242c of the actuating component 3242b moves between the end of the first groove and the end of the second groove, it will correspondingly drive the shift gear ring 3221 to move between the locked position and the free position along the transmission axis x2.

[0113] Preferably, the protrusion 3421c can be arranged in pairs, and the guide groove 3242d is also set to two accordingly, so that the shift ring 3221 can be subjected to force on both sides at the same time and reliably move linearly along the transmission axis x2.

[0114] In other embodiments, to determine the current gear position of the transmission assembly 32 and achieve automatic gear switching and control, please refer to [further details needed]. Figure 6 The automatic gear shifting mechanism 324 also includes a gear position detection device 3243.

[0115] The gear position detection device 3243 is a sensor used to detect the position of the shift paddle 3242a. It can be fixed in a position close to the transmission mechanism housing and the shift paddle 3242a, and outputs different electrical signals based on the different positions of the shift paddle 3242a.

[0116] For example, when the shift paddle 3242a is detected to be in the first position, the gear position detection device 3423 outputs a first electrical signal, and when the shift paddle 3242a is detected to be in the second position, the gear position detection device 3243 outputs a second electrical signal, so that the control device 50 can determine the gear currently used by the transmission assembly 32.

[0117] Depending on the needs of the actual application, the gear position detection device 3243 can employ any suitable type of sensor device based on various principles. For example, the gear position detection device 3243 can be a Hall sensor, which detects the position of the shift paddle 3242a by detecting changes in the magnetic field signal caused by the shift paddle 3242a.

[0118] To avoid erroneous triggering and ensure that the mop is reliably and correctly positioned within the cleaning space when the drive unit initiates the aforementioned spin-drying and cleaning operations, in some embodiments, such as... Figure 16 As shown, the mop also includes a detection device 60.

[0119] The detection device 60 is a sensor used to detect whether the mop is properly inserted. It is installed on the mop bucket body and can generate a positioning signal when the mop 1 is positioned in the cleaning space, and generate a disengagement signal, which is different from the positioning signal, when the mop 1 is detected to have left the cleaning space.

[0120] The detection device 60 is further electrically connected to the control device 50, enabling the control device 50 to detect whether the mop is properly inserted via the positioning / disengagement signal provided by the detection device 60. Accordingly, the control device 50 switches to the positioned state when it receives the positioning signal, and remains in the disengaged state when it does not.

[0121] Specifically, the first triggering condition set by the control device 50 includes receiving a pedal signal in the positioned state. In other words, the control device 50 only considers the first triggering condition met when it receives the pedal signal after acquiring the positioned signal and switching to the positioned state (confirming that the mop is now inserted). The control device 50 then controls the drive device 30 to sequentially perform one cleaning operation and one spin-drying operation. If the device is in the disengaged state, it will not be considered that the first triggering condition has been met regardless of whether a pedal signal is received.

[0122] like Figure 10 As shown, a typical mop 2 mainly consists of a relatively long mop handle 201 and a relatively wide and flat mop head 202. Multiple cleaning strips 203 are fixed to the mop head 202. These cleaning strips 203 are made of flexible strip-shaped materials such as fibers and are fixed to the mop head 202 for cleaning the floor.

[0123] During cleaning and wringing operations, the mop head 202 can be reliably housed and fixed within the inner tub 20 via a locking mechanism 23 located at the bottom of the tub. However, the mop handle 201 may still swing or shift position as the inner tub rotates, requiring the user to hold it to ensure the mop handle 201 remains stable.

[0124] In some embodiments, in order to effectively support the mop handle 201 and simplify the user's operation, such as... Figure 11 and Figure 12 As shown, the mop bucket may also include: a mop bucket handle 70.

[0125] The mop handle 70 is positioned across the top opening of the mop body 10 and can rotate around a set handle axis x3 between a limiting position away from the mop body and a storage position close to the mop body.

[0126] Depending on the needs of practical applications, the mop handle 70 can be in various shapes and lengths. For example, as Figure 13 As shown, the mop handle 70 can be an arc-shaped handle that extends along the arc direction for a predetermined length, and a limiting groove 71 is provided in the middle of the arc-shaped handle to lock and accommodate the mop handle 201.

[0127] Alternatively, a raised structure is provided in the middle of the arc-shaped handle, and a limiting groove adapted to the raised structure is provided at the mop handle 201 to achieve a snap-fit ​​between the two.

[0128] In this embodiment, the two ends of the mop handle 70 that are far apart from each other in the length direction are referred to as the "first handle end" and the "second handle end". The first handle end and the second handle end are arranged opposite each other along the handle axis x3 and are respectively connected to the side wall pivot of the mop body, so that the mop handle 70 as a whole can rotate around the set handle axis x3.

[0129] Please continue reading. Figure 12 When the mop handle 70 is rotated to the limit position, the mop handle 70 engages with the mop handle 201 of the mop 2 inserted in the cleaning space, thereby positioning the mop. The user does not need to hold the mop handle 201 to maintain its position during cleaning and wringing operations.

[0130] In some embodiments, the limiting groove 71 is a recess that is adapted to the mop handle 201, so that when the mop handle 70 is rotated to the limiting position, the mop handle 201 can be locked in the limiting groove 71, thereby achieving a locking engagement between the two.

[0131] Specifically, the "matching recess" refers to the fact that the limiting groove has space to accommodate the mop handle 201, so that the mop handle 201 can be locked in the limiting groove. The recessed space formed by the limiting groove 71 can be greater than or equal to the cross-section of the corresponding position of the mop handle 201.

[0132] For example, when the mop handle 201 is basically cylindrical, at least a portion of the limiting groove 71 is set as a semicircle that matches the outer periphery of the cylinder, so that the mop handle 201 is reliably locked in the semicircular recess of the limiting groove 71 and is not easy to come out.

[0133] Specifically, the "limited position" refers to the position where the mop handle 70 rotates to engage with the mop handle 201. For example, as Figure 11 As shown, the limiting position is when the mop handle 70 is rotated to a position substantially perpendicular to the top opening of the mop body.

[0134] Alternatively, the limiting position can also be any position where the mop handle 70 is rotated to other angles, as long as it can engage with the mop handle 201 and remain basically stable.

[0135] Preferably, when the mop handle 70 is rotated to the limit position, the limiting groove 71 is aligned with the axis x1 of the bucket body. This positioning can support the mop handle 201, keeping it aligned with the axis of the bucket body, which helps to keep the position of the mop 2 stable when the inner bucket 20 rotates around the axis of the bucket body.

[0136] Here, "alignment" means that the center of the limiting groove 71 is substantially located on the barrel axis x1. For example, when using the aforementioned limiting groove 71 that is at least partially semi-circular, the center of the semi-circle coincides with the barrel axis x1.

[0137] Based on the aforementioned practical application scenario of using the mop handle 70 to engage and position the mop inserted in the cleaning space, in some embodiments, the detection device 60 can be a positioning sensor for detecting the current position of the mop handle 70.

[0138] When it detects that the mop handle 70 has rotated to the limit position, it outputs a positioning signal. When it detects that the mop handle 70 has left the limit position and started to rotate towards the storage position, it outputs a disengagement signal, thereby indirectly realizing the detection of whether the mop has been correctly positioned.

[0139] Depending on the specific application requirements, any suitable implementation method can be used to implement the position sensor's detection function. For example, such as... Figure 14 and Figure 15 As shown, the end of the first handle is also provided with a trigger protrusion 72. Correspondingly, the detection device includes a micro switch 61 disposed on the main body of the mop.

[0140] The trigger protrusion 72 is an elongated strip-shaped structure extending in a preset direction. The microswitch 61 is a controllable switching element. Through its internal spring mechanism and contact structure, it can convert changes in the force exerted by an external mechanical structure into changes in the on / off state of an electrical circuit. The microswitch 61 is equipped with a drive unit 62 for receiving direct forces from the external mechanical structure. This drive unit 62 transmits these direct forces to the contact mechanism inside the microswitch 61, thereby realizing the switching action control of the microswitch 61.

[0141] like Figure 15 As shown, the micro switch 61 is positioned close to the end of the first handle, and the distance between it and the end of the first handle is less than the extension length of the trigger protrusion 72. Therefore, the trigger protrusion 72 can contact the drive portion 62 of the micro switch 61 as the end of the first handle rotates.

[0142] In actual use, when the mop handle 70 rotates to the limit position, the trigger protrusion 72 at the end of the first handle contacts the drive part 62 of the micro switch 61, controlling it to switch from the off state to the on state (or from the on state to the off state), thereby changing the circuit connection and triggering the detection device 60 to generate a positioning signal. When the mop handle 70 rotates in the reverse direction to the storage position, the trigger protrusion 71 at the end of the first handle also rotates in the reverse direction, contacting the drive part 62 of the micro switch 61 to control it to return to the off state (or the on state), thereby restoring the circuit connection to its initial state and maintaining the output disconnection signal from the detection device.

[0143] As mentioned earlier, after one spin-drying operation, the water in the washing space K11 is drained into the water storage space K12. To facilitate the next mop washing and spin-drying operation, in some embodiments, please refer to [the relevant documentation / reference needed]. Figure 16 The tub also includes a water filling device 80.

[0144] The water injection device 80 forms a conveying channel connecting the cleaning space K11 and the water storage space K12, and can actively pump the water in the water storage space K12 back into the cleaning space K11 to complete the water injection operation.

[0145] For details, please continue reading. Figure 3 The inlet J1 of the conveying channel is located inside the water storage space K12, while the outlet J2 of the conveying channel is higher than the inner barrel side wall 22, so that the water sprayed from the outlet J2 can smoothly enter the cleaning space K11.

[0146] Preferably, the outlet J2 of the delivery pipe can be further configured to protrude from the inner wall of the tub body 10. This protrusion of the outlet J2 into the cavity K1 facilitates the flow of water sprayed from it into the cleaning space K11.

[0147] In this embodiment, the water injection device 80 is also electrically connected to the control device 50. The control device 50 controls the operation of the water injection device 80 based on whether a preset trigger condition is met.

[0148] To distinguish it from the triggering conditions for the aforementioned cleaning and spin-drying operations, the term "second triggering condition" will be used below to refer to the triggering condition for the water injection operation. In other words, each time the control device 50 detects that the second triggering condition is met, it controls the water injection device 80 to perform a water injection operation, re-injecting the water in the water storage space K12 into the cleaning space K11.

[0149] Specifically, the second triggering condition includes: a preset first waiting time elapsed after the spin-drying operation ends. This preset first waiting time is set according to actual needs. This method of automatically refilling the mop after the first waiting time improves the automation level of the mop and reduces the number of user operations.

[0150] Alternatively, the second triggering condition can also be: detecting a disengagement signal after the spin-drying operation has ended and a preset second waiting time has elapsed, or detecting a pedal signal after the spin-drying operation has ended. When a disengagement signal is detected or a pedal signal actively applied by the user is detected, it can be reasonably assumed that the mop has been removed from the cleaning space and is now in the process of mopping. Therefore, initiating a water filling operation accordingly ensures that preparations for both the cleaning and spin-drying operations are completed before the mop is inserted, saving time and improving efficiency.

[0151] It should be noted that the first waiting time and the second waiting time can be set to the same duration or to different durations to adapt to different practical application scenarios.

[0152] In some embodiments, such as Figure 14 As shown, the water injection device 80 includes a water pump 81 and a delivery pipe 82.

[0153] Among them, the water pump 81 is a liquid driving device that drives the liquid to flow in a set direction. It can convert electrical energy into mechanical energy and apply pressure to the liquid, so that the liquid entering from the water pump inlet is pumped out from the water pump outlet at a set pressure.

[0154] Please refer to the following in this application: Figure 3The water pump 81, as an electrical device, is also fixed in the equipment housing cavity K2, with only the water pump inlet passing through the isolation structure 11 and being placed in the water storage space K12 as the water inlet J1 of the conveying channel.

[0155] The conveying pipe 82 is a hollow pipe with a predetermined length. Its two ends, which are far apart in the length direction, are respectively called the "inlet end" and the "outlet end". The inlet end of the conveying pipe 82 is sealed to the outlet of the water pump, and the outlet end of the conveying pipe 82 forms the outlet J2 of the conveying channel.

[0156] Therefore, when the water pump 81 is started, the water in the water storage space K12 will enter from the water pump inlet under the action of the water pump 81 and then be discharged from the outlet of the conveying pipe 82 and re-enter the cleaning space K11.

[0157] To further improve cleaning performance and enhance the water quality used for rinsing the mop, in some embodiments, please refer to... Figure 3 The mop also includes a filter device 83. Accordingly, an additional filter chamber K13 is formed within the cavity of the mop body 10.

[0158] The filter chamber K13 is a relatively independent cavity formed within the cavity K1 by the isolation structure 11. It is connected to the water storage space K11 through the filter device 83. The water inlet J1 (i.e., the water pump inlet) is located inside the filter chamber K13. Thus, the water in the water storage space K11 is filtered by the filter device 83 before entering the water pump 81, removing larger impurities and contaminants.

[0159] The additional filter device 83 and filter chamber K13 reduce backflow of dirt and prevent secondary pollution when washing the mop. Furthermore, they prevent larger particles from entering the water pump, thus avoiding pump blockage or component wear and extending the pump's lifespan.

[0160] To fully describe the inventive concept of the embodiments of this application, the specific usage process of the mop bucket is described in detail below. For example... Figure 17 As shown, the process of using the mop bucket includes the following steps: S110. Pour an appropriate amount of water into the water storage space K12.

[0161] The specific amount of water injected can be determined by one or more prompts, such as setting a water level indicator on the mop body 10, to help the user determine the amount.

[0162] In some embodiments, before filling the mop body 10 with water, the inner tub 20 can be removed to facilitate water filling. Then, after water filling is completed, the inner tub 20 is rotatably reassembled into the mop body 10 to establish a transmission connection with the drive device.

[0163] Alternatively, water can be directly injected into the tub body 10 equipped with the inner tub 20, filling the water storage space K12. This simplifies the disassembly and assembly of the inner tub 20.

[0164] S120: The user performs an interactive operation on switch 54 to start control device 50 and switch it to the running state.

[0165] As mentioned above, switch 54 is the main control switch for starting the mop bucket operation. Users can apply corresponding interactive operations to activate the control device 50 and put it into operation, depending on the specific settings of the switch. For example, switch 54 can be a spring-loaded button on the mop bucket body, allowing users to switch the state of the control device 50 by pressing the spring-loaded button.

[0166] S210 After the control device 50 switches to the running state, it outputs the corresponding control signal to the water injection device 80 to control the water injection device 80 to perform the first water injection operation.

[0167] When the control device 50 is activated, it first controls the water injection device 80 to inject water, so that the cleaning space K11 has enough water to prepare for cleaning the mop.

[0168] After receiving the control signal from the control device 50, the water injection device 80 performs the first water injection operation, pumping part of the water in the water storage space K12 into the cleaning space K11.

[0169] S130. The user inserts the mop 2 into the inner tub 20 so that the mop head 202 of the mop 2 engages with the locking structure 23 of the inner tub 20, thereby fixing the mop head 202 in the position within the inner tub 20.

[0170] The locking structure 23 can be a protrusion extending from the bottom of the bucket. The center of the protrusion coincides with the axis of the bucket body to ensure that the mop head 202 remains in a stable position during the rotation of the inner bucket.

[0171] S140, The user rotates the mop handle 70 to a limit position away from the mop body, and engages with the mop handle 201 of the mop 2.

[0172] The snap-fit ​​between the mop bucket handle 70 and the mop handle 201 provides another support point for the mop. This, together with the inner bucket 20 and the mop head 202, forms a support point to achieve the positioning of the mop 2 inserted in the cleaning space K11.

[0173] S230. As the mop handle 70 is rotated to the limit position, the detection device 60 will detect the position change of the mop handle 70 and output a position signal to the control device 50.

[0174] S150, The user performs an interactive operation on the trigger pedal 40 and presses down the trigger pedal 40.

[0175] After completing step S140 and positioning the mop 2 in the mop bucket 1, the user can trigger the mop bucket to perform cleaning and wringing operations on the mop 2 by lightly stepping on the trigger pedal 40 once.

[0176] S240. As the trigger pedal 40 receives an applied external force, the trigger pedal 40 will generate a pedal signal and output it to the control device 50.

[0177] S250: After receiving the pedal signal, the control device 50 determines that the first triggering condition is met because the detection device 60 is continuously outputting a position signal. Therefore, it outputs a corresponding triggering command to the drive device 30.

[0178] The trigger command can be any suitable type of electrical signal as needed, and no specific limitation is made here.

[0179] Since the control device 50 automatically outputs a control signal to trigger the cleaning and spin-drying operations after detecting the pedal signal, in step S140, the user only needs to press the trigger pedal 40 briefly or once, without needing to keep the trigger pedal 40 pressed for an extended period.

[0180] Furthermore, by using the positioning signal output by the detection device 60 as a judgment condition, the inner tub can be prevented from rotating incorrectly before the mop is fully and reliably positioned.

[0181] S260: After receiving the trigger command from the control device 50, the drive device 30 sequentially performs a cleaning operation and a spin-drying operation.

[0182] The cleaning operation involves using a larger torque to drive the inner tub to rotate at a smaller speed for a set time, during which the water in the cleaning space K11 rinses the mop 1, thus cleaning the mop. The spin-drying operation involves using a smaller torque to drive the inner tub 20 to rotate at a larger speed continuously for a set time, using centrifugal force to spin the water in the cleaning space K11 and the water in the mop head 22 into the water storage space K12 for temporary storage.

[0183] S160. After the spin-drying operation is completed, the user rotates the mop handle 70 back to the storage position, releases the locking engagement between the mop handle 70 and the mop handle 201, and removes the mop 2 from the mop bucket 1.

[0184] As the bucket handle 70 rotates away from the limit position, the detection device 60 outputs a disengagement signal and no longer provides a positioning signal to the control device 50.

[0185] S270 After detecting that the second triggering condition is met, the control device 50 outputs a corresponding control signal to the water injection device 80 to control the water injection device 80 to perform a water injection operation.

[0186] The second trigger condition can be a preset time elapsed after the spin-drying operation ends. The control device 50 can use built-in electronic devices such as a timer to keep track of this preset time.

[0187] After receiving the control signal from the control device 50, the water injection device 80 performs the corresponding water injection operation, pumping part of the water in the water storage space K12 back into the cleaning space K11.

[0188] After the water filling device 80 completes the water filling operation, the cleaning space K11 is replenished with sufficient water for cleaning. The mop bucket 1 allows the mop 2 to be reinserted for the next cleaning and wringing operation.

[0189] In summary, in actual use, the mop provided in this application only requires the user to step on the trigger pedal once to enable the mop to automatically complete the complete work cycle of cleaning, wringing, and water filling in sequence.

[0190] This type of mop significantly reduces the user's workload and simplifies the interactive operations required. Compared to the cumbersome methods of existing electric mops, it offers greater human-computer interaction friendliness.

[0192] Furthermore, when the technical features involved in different embodiments are not explicitly described or explained in the relevance and association section as conflicting with each other, they can be combined to obtain more embodiments.

Those skilled in the art can make various modifications and improvements without departing from the concept of this application, and all of these fall within the scope of protection of this application.
