Description

Technical Field

[0001] This utility model relates to the technical field of cleaning tools, specifically to a handle structure, cleaning equipment, and cleaning system. Background Technology

[0002] Cleaning equipment such as floor scrubbers or carpet scrubbers generally include a main body, a floor brush mechanism at the bottom of the main body, and a handle structure at the top of the main body. During cleaning, users hold the handle structure to adjust and control the working direction of the floor scrubber. Floor scrubbers or carpet scrubbers are relatively large and heavy, so users may feel tired if they operate them manually for a long time. To improve user comfort, modern floor scrubbers are equipped with auxiliary wheels on the floor brush mechanism. These auxiliary wheels rotate forward or backward on the ground, moving the cleaning equipment and reducing the force applied by the user, thus making the floor scrubber or carpet scrubber easier to use.

[0003] However, the movement direction of traditional auxiliary wheels is unclear and inconsistent with the user's intention. Furthermore, the auxiliary wheels are not sensitive when changing their rotation direction. In other words, the user cannot promptly and accurately convey their movement intention to the cleaning equipment to change the speed and direction of the auxiliary wheels, resulting in a poor user experience. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is that the movement trend of the auxiliary wheel of traditional cleaning equipment fails to meet the user's intention, resulting in a poor user experience.

[0018] Each of the aforementioned sensing elements is configured as a mechanical micro switch, a Hall effect switch, or a photoelectric switch; or,

[0019] The trigger part is integrally formed with the handle.

[0020] Optionally, the handle is cylindrical, and the handle body is movably sleeved inside the handle; the handle structure also includes a trigger connected to the inside of the handle, and the trigger part is disposed on the trigger.

[0021] The trigger is disposed between the handle and the handle body, and one of the trigger and the handle body is provided with a groove, while the other is provided with a sliding post that is slidably inserted into the groove. The groove extends along the axial direction of the handle.

[0022] Optionally, the groove is provided on the handle body;

[0023] The handle structure further includes a connector that connects the handle and the trigger and is at least partially protruding from the trigger to slide into the groove, the connector forming the sliding post.

[0024] Optionally, two connectors are provided, and the slide groove includes a first groove segment and a second groove segment that are separated along the axial direction of the handle, and the two connectors are slidably inserted into the first groove segment and the second groove segment respectively;

[0025] In the first operating state, the connector located within the first slot abuts against the end of the first slot facing away from the second slot; in the second operating state, the connector located within the second slot abuts against the end of the second slot facing away from the first slot; and / or,

[0027] Optionally, the handle structure also has an initial state between the first working state and the second working state, in which both trigger parts are located outside the sensing areas of the two sensing parts.

[0030] This utility model also provides a cleaning device, including:

[0034] This utility model also provides a cleaning system, including the above-mentioned cleaning equipment and a base station, wherein the base station can be used to house the cleaning equipment.

[0035] The technical solution provided by this utility model has the following advantages:

[0036] This utility model provides a handle structure for cleaning equipment, including a handle body, a handle rod, a triggering part, and a sensing part. The handle body is for the user to hold, and moving the handle body drives the entire cleaning equipment to move in the corresponding direction. The handle rod connects the handle body and the equipment body, allowing the handle body to be positioned at a suitable height for the user to hold, making operation of the cleaning equipment easier and allowing for a wider cleaning range when the user is standing still. When the handle structure is applied to the cleaning equipment, one end of the handle rod is fixed to the equipment body, while the handle body can move relative to the axial, length, or circumferential direction of the handle rod, allowing the handle body to move in the corresponding direction. The movement of the handle moves the sensing unit, allowing the trigger unit to move into the sensing area of ​​the sensing unit. This triggers the sensing unit to issue a corresponding working command, controlling the auxiliary wheel on the main body of the device. The operation of the auxiliary wheel can be controlled by moving the handle. Furthermore, the force applied by the user can be less than the force required to move the cleaning device. When the user's force on the handle tends to move forward or backward, the coordination of the sensing unit and the trigger unit drives the auxiliary wheel to rotate, making operation more convenient. Simultaneously, the active rotation of the auxiliary wheel makes the cleaning device move more smoothly and requires less effort from the user. Moreover, when the user adjusts the cleaning direction of the device, for example, by pushing the device forward, a forward force is applied directly to the handle. This force drives the handle to move, and through the movement of the sensing unit, the trigger unit is positioned within the sensing area. The signal from the sensing unit activates the drive mechanism to rotate the auxiliary wheel forward, and vice versa. Users do not need to provide additional driving force or force to the handle structure. They only need to provide a moving force to the handle body to drive the auxiliary wheel to rotate. This makes it simpler and less strenuous for users to operate, and the cleaning equipment works more smoothly. Attached Figure Description

Detailed Implementation

[0048] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described solution is only a part of the solution of this utility model, not all of it. The present utility model will be described in detail below with reference to the accompanying drawings and the solution. It should be noted that, unless otherwise specified, the solutions and features of this utility model can be combined with each other.

[0049] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0050] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0051] This utility model provides a handle structure 100 for use in cleaning equipment. The handle structure 100 is adaptable to cleaning equipment, allowing users to move the equipment by gripping it. For details, please refer to... Figures 1 to 2 The handle structure 100 includes a handle body 1, a handle 2, a triggering part, and a sensing part; one end of the handle 2 is movably connected to the handle body 1, and the other end is adapted to be connected to the main body of the device; the triggering part is provided on the handle 2; the sensing part is provided on the handle body 1 and is provided corresponding to the triggering part; when the handle body 1 is subjected to external force, it moves relative to the handle 2 in the axial, length, or circumferential direction, causing the sensing part to move together, so that the sensing part can be triggered by the triggering part to work.

[0052] In this design, the handle body 1 is for the user to hold, and moving the handle body 1 drives the entire cleaning device to move in the corresponding direction. The handle 2 connects the handle body 1 and the device body, allowing the handle body 1 to be positioned at a height suitable for the user's grip, making operation of the cleaning device easier and allowing for a wider cleaning range when the user is standing still. When the handle structure 100 is applied to the cleaning device, one end of the handle 2 is fixed to the device body, and the handle body 1 can move relative to the handle 2 in the axial, length, or circumferential direction. This movement of the handle body 1 drives the sensing part to move as well, allowing the trigger part to move into the sensing area of ​​the sensing part, thereby triggering the sensing part to work and issue a corresponding working command, thus controlling the auxiliary wheel on the device body. The operation of the auxiliary wheel can be controlled by the movement of the handle body 1. The force applied by the user can be less than the force required to move the cleaning device. This allows the auxiliary wheel to rotate when the user's force on the handle body 1 tends to move forward or backward, through the cooperation of the sensing and triggering units. The active rotation of the auxiliary wheel makes the cleaning device move more smoothly and requires less effort from the user. Furthermore, when the user adjusts the cleaning direction, for example, by pushing the device forward, a forward force is directly applied to the handle body 1. This force drives the handle body 1 to move, and through the movement of the sensing unit, the triggering unit is positioned within its sensing area. The signal from the sensing unit activates the drive mechanism to rotate the auxiliary wheel forward, and vice versa. The user does not need to provide additional driving or force to the handle structure 100; only a single moving force is required to rotate the auxiliary wheel. This makes operation simpler and less strenuous, and the cleaning device operates more smoothly.

[0053] Among them, combined Figure 1 and Figure 2As shown, the handle body 1 includes a grip portion 11 and a connecting portion 12. The grip portion 11 is ring-shaped, providing a cavity for the hand to extend into. The outer ring of the grip portion 11 is arc-shaped, which is more ergonomic and provides better comfort for the user's hand. The connecting portion 12 is used to connect to the handle 2, and the connecting portion 12 can move relative to the handle 2 after being connected. For example, the connecting portion 12 can rotate, translate, or rotate relative to the handle 2. The movement of the connecting portion 12 makes the entire handle body 1 movable, thereby driving the sensor provided on the connecting portion 12 to move, so that a relative displacement is formed between the trigger portion and the sensor portion. The trigger portion can move to the sensing area and outside the sensing area of ​​the sensor portion. When the sensor portion moves to a position where the trigger portion is within the sensing area of ​​the sensor portion, the trigger portion activates the sensor portion. When the handle structure 100 is applied to a cleaning device, by electrically connecting the sensing unit to the drive mechanism on the cleaning device and driving the drive mechanism to the auxiliary wheel on the cleaning device, the driving mechanism is activated by the sensing unit, thereby driving the auxiliary wheel on the cleaning device to rotate, thereby improving the smoothness of the cleaning device's movement and saving the user's physical effort.

[0054] Preferably, the shape of the handle 2 is adapted to the shape of the connecting part 12. Connecting the device body and the handle body 1 via the handle 2 allows the handle body 1 to be positioned relatively higher, enabling the user to grip it without bending over, thus improving comfort when using the cleaning equipment. The handle 2 is generally cylindrical with openings at both ends. One end of the connecting part 12 is connected to the grip part 11, and the other end is fitted into one end of the handle 2. The other end of the handle 2 is adapted to be connected to the device body. The handle 2 is detachably connected to the device body, making the handle structure 100 easy to detach from the device body, facilitating the use and storage of the cleaning equipment.

[0055] Moreover, combined Figure 2 and Figure 4As shown, the gripping part 11 is disposed outside the handle 2, and the connecting part 12 is movably sleeved inside the handle 2. A recess or protrusion 122 is formed on the outer peripheral side of the connecting part 12, so that a gap suitable for communicating between the inner cavity of the handle 2 and the outside is formed between the connecting part 12 and the handle 2. Preferably, a protrusion 122 extending axially is provided on the outer peripheral side of the connecting part 12, and multiple protrusions 122 are provided. The multiple protrusions 122 are arranged at intervals along the circumference of the connecting part 12, and an airflow gap is formed between each two adjacent protrusions 122. During the movement of the connecting part 12 relative to the handle 2, multiple protrusions 122 contact the inner wall of the handle 2. Through the airflow gap between each pair of adjacent protrusions 122, the airflow gap can connect the inside of the handle 2 with the outside. Thus, when the handle body 1 moves downward relative to the handle 2, the downward movement of the handle body 1 will not be restricted due to the gradual increase of the internal pressure of the handle 2, nor will the movement of the handle body 1 be difficult. Similarly, when the handle body 1 moves upward, the upward movement of the handle body 1 will not be restricted due to the gradual decrease of the internal pressure of the handle 2, nor will the movement of the handle body 1 be difficult. This makes it easier and smoother for the user to operate the handle body 1.

[0056] It should be noted that when the cleaning device is in normal placement, the handle 2 is axially positioned in the vertical direction, the handle body 1 is located at the top of the handle 2, and the bottom of the handle 2 is connected to the main body of the cleaning device. Unless otherwise specified, all descriptions of orientation in this utility model shall be taken as above.

[0057] Furthermore, preferably, the handle body 1 has a reciprocating stroke along the axial direction of the handle 2, so that the linear movement of the handle body 1 drives the sensing part to move, so that the sensing part can approach the triggering part to trigger the sensing part to be in different working states.

[0058] It is understandable that, depending on the different working states of the cleaning equipment, different numbers of sensors and triggers can be set to achieve multiple functions of the cleaning equipment. In this solution, when the trigger triggers the sensor, the sensor is mainly used to control the operation of the drive mechanism on the floor brush mechanism of the cleaning equipment, and the drive mechanism drives the auxiliary wheel to rotate forward or backward to assist the cleaning equipment in moving forward or backward. Therefore, preferably, the handle structure 100 has at least two working states: a first working state that causes the auxiliary wheel to rotate forward, and a second working state that causes the auxiliary wheel to rotate backward. Specifically, the rotation direction of the auxiliary wheel can be controlled by controlling the rotation direction of the drive mechanism. Therefore, the two working states can be switched by triggering different triggers and different sensors.

[0059] In one embodiment, there is one triggering unit and two sensing units. One triggering unit can activate both sensing units respectively, so that the handle structure 100 can be in a first working state and a second working state respectively. The two sensing units can be a first sensing unit 41 and a second sensing unit 42, which trigger the operation of the auxiliary wheel by applying external force to the handle body 1. Because the entire handle structure 100 is tilted during cleaning, when the user pushes the handle body 1 forward to control the cleaning device to move forward, the handle body 1 receives a downward force, causing it to move downward relative to the handle 2. Simultaneously, this causes the first sensing part 41 and the second sensing part 42 to move, moving the trigger part into the sensing area of ​​the first sensing part 41. This triggers the auxiliary wheel to rotate forward, providing forward assistance to the cleaning device. Conversely, when the user pulls the handle body 1 backward to control the cleaning device to move backward, the handle body 1 receives an upward force, causing it to move upward relative to the handle 2. This also causes the first sensing part 41 and the second sensing part 42 to move, moving the trigger part into the sensing area of ​​the second sensing part 42. This triggers the auxiliary wheel to rotate backward, providing backward assistance to the cleaning device. Therefore, the auxiliary wheel's rotation provides better forward and backward movement power, making the cleaning device move more smoothly.

[0060] In another embodiment, two triggering parts and one sensing part are provided. The two triggering parts can respectively activate the sensing part, so that the handle structure 100 can be in a first working state and a second working state. The two triggering parts can be a first triggering part 31 and a second triggering part 32. By applying an external force to the handle body 1, the auxiliary wheel can be activated. Similarly, when the user pushes the handle body 1 forward to control the cleaning device to move forward, the handle body 1 can be subjected to a downward force, which drives the handle body 1 to move downward relative to the handle 2, thereby moving the sensing part and causing the first triggering part 31 to move into the sensing area of ​​the sensing part, thereby triggering the auxiliary wheel to rotate forward, thus providing forward assistance to the cleaning device. Conversely, when the user pulls the handle body 1 backward to control the cleaning device to move backward, the handle body 1 can be subjected to an upward force, which drives the handle body 1 to move upward relative to the handle 2, thereby moving the sensing part and causing the second triggering part 32 to move into the sensing area of ​​the sensing part, thereby triggering the auxiliary wheel to rotate backward, thus providing backward assistance to the cleaning device.

[0061] Preferably, combined with Figures 3 to 5As shown, there are two triggering parts and two sensing parts. The two triggering parts can each trigger one of the two sensing parts to work, so that the handle structure 100 can be in a first working state and a second working state, respectively. This allows the handle structure 100 to have a first working state where one triggering part triggers a corresponding sensing part, and a second working state where the other triggering part triggers another corresponding sensing part. The two triggering parts can be a first triggering part 31 and a second triggering part 32, and the two sensing parts can be a first sensing part 41 and a second sensing part 42. The first triggering part 31 and the second triggering part 32 are arranged at intervals along the axial direction of the handle 2, and the first sensing part 41 and the second sensing part 42 are also arranged at intervals along the axial direction of the handle 2. Figure 3 As shown, when the user pushes the handle body 1 forward to control the cleaning device to move forward, the handle body 1 can be subjected to a downward force, causing the handle body 1 to move downward relative to the handle 2, thereby driving the first sensing part 41 and the second sensing part 42 to move together. This causes the first trigger part 31 to move into the sensing area of ​​the first sensing part 41, while the second trigger part 32 is located outside the sensing area of ​​the second sensing part 42. At this time, the first trigger part 31 triggers the first sensing part 41 to work, thereby causing the auxiliary wheel to rotate forward to provide forward assistance to the cleaning device; conversely, combined with Figure 4 As shown, when the user pulls the handle body 1 backward to control the cleaning device to move backward, the handle body 1 receives an upward force, causing it to move upward relative to the handle 2. This moves the first sensing part 41 and the second sensing part 42, causing the second trigger part 32 to move into the sensing area of ​​the second sensing part 42, while the first trigger part 31 is located outside the sensing area of ​​the first sensing part 41. This triggers the auxiliary wheel to rotate backward, providing a backward assist force to the cleaning device. Through the interaction between the first trigger part 31 and the first sensing part 41, and through the interaction between the second trigger part 32 and the second sensing part 42, compared to a single sensing part or a single trigger part, the relative travel distance between the first sensing part 41 and the second sensing part 42 can be reduced. Therefore, the overall movement of the handle body 1 can be smaller, saving space and reducing operating effort. When the force applied by the user to the handle body 1 is less than the friction between the brush mechanism and the surface to be cleaned (such as the ground), the drive mechanism can be activated through the cooperation of the sensing and triggering parts to drive the auxiliary wheel to rotate. The user can drive the auxiliary wheel to rotate without pushing the cleaning device, so the user can operate the cleaning device with less effort, and the active rotation of the auxiliary wheel makes the movement of the cleaning device smoother.

[0062] In one embodiment, each trigger can be mounted on the main body of the handle 2 and integrated with the handle 2, resulting in fewer assembly parts and easier installation of the handle structure 100.

[0063] In another embodiment, each trigger is formed on a separate component. Specifically, the handle structure 100 also includes a trigger member connected to the inside of the handle 2. The trigger member is located between the handle 2 and the handle body 1, and the trigger part is formed on the trigger member. The trigger member is fixedly connected to the handle 2, and the sensing part can move relative to the trigger member by moving the handle body 1. Furthermore, the trigger member is detachably connected to the handle 2, resulting in fewer external disassembly parts, a simpler appearance, lower cost, and easier assembly and disassembly. It also facilitates the maintenance of the trigger member, making the manufacturing process of the handle 2 simpler. Moreover, by fixing the trigger member to the inside of the handle 2, when the handle structure 100 changes position during operation of the cleaning equipment, the trigger member will not move relative to the body due to the change in position. Therefore, the impact on the sensing of the trigger and sensing parts is smaller, which better ensures the sensing sensitivity of the trigger and sensing parts, and the status recognition is more accurate.

[0064] In one embodiment, the trigger can be a sheet-like object formed on one side of the handle body 1. The triggering parts at both ends of the trigger trigger the upper sensing part of the handle body 1, thereby switching between a first working state and a second working state.

[0065] In another embodiment, the trigger element is a trigger cylinder 3, which is a cylindrical shape open at both ends and fitted onto the outside of the connecting part 12 of the handle body 1. The trigger element is fixedly connected to the handle 2, and two trigger parts are respectively located at both ends of the axial direction of the trigger cylinder 3. Specifically, the trigger element and the handle 2 can be connected by a connector, which can be a stud or pin, etc., to ensure a more reliable connection between the trigger element and the handle 2. Moreover, multiple connectors can be provided, and multiple connectors are arranged at intervals along the axial direction of the trigger cylinder 3 to ensure a more stable connection of the trigger cylinder 3 inside the handle 2 and to prevent it from shaking.

[0066] The trigger cylinder 3 may include two radially connected semi-cylinders, which are connected and fixed by a snap-fit ​​structure, so as to allow the trigger cylinder 3 to be fitted onto the outside of the handle body 1. During assembly, the trigger cylinder 3 and the handle body 1 can be assembled first, and then the whole assembly can be fitted onto the inside of the handle 2, making assembly more convenient.

[0067] Moreover, combined Figure 7 and Figure 8As shown, a groove 121 is provided on one of the trigger and the handle body 1, and a sliding post is provided on the other, which is slidably inserted into the groove 121. The groove 121 extends axially along the handle 2. Through the cooperation of the groove 121 and the sliding post, on the one hand, the handle body 1 is less likely to wobble when moving relative to the trigger; on the other hand, the sliding post, in cooperation with the groove 121, can limit the movement stroke of the handle body 1, preventing excessive movement. Preferably, the connecting member can form the sliding post. While connecting the handle 2 and the trigger cylinder 3, at least a portion of the connecting member can extend into the groove 121 to guide and limit the movement of the handle body 1.

[0068] Preferably, such as Figure 8 As shown, there are two connectors. The slide groove 121 includes a first groove segment 1211 and a second groove segment 1212 that are separated along the axial direction of the handle 2. The two connectors are slidably inserted into the first groove segment 1211 and the second groove segment 1212, respectively. In the first working state, the connector located in the first groove segment 1211 abuts against the end of the first groove segment 1211 facing away from the second groove segment 1212, thereby restricting the handle body 1 from moving downward continuously. In the second working state, the connector located in the second groove segment 1212 abuts against the end of the second groove segment 1212 facing away from the first groove segment 1211, thereby restricting the handle body 1 from moving upward continuously and better preventing the handle body 1 from dislodging from the handle 2.

[0069] Moreover, combined Figure 5 As shown, the handle structure 100 also has an initial state between a first working state and a second working state. In the initial state, both trigger parts are located outside the sensing areas of the two sensing parts, so that the auxiliary wheel does not rotate. When the cleaning device is in a stationary cleaning or placement state, the cleaning device does not need to move forward or backward. At this time, the handle structure 100 can remain in the initial state, so that the auxiliary wheel does not rotate, and the drive mechanism does not need to work, thus saving more energy.

[0070] Specifically, the handle structure 100 also includes two elastic telescopic members 5. When the handle structure 100 is in a first working state under the action of an external force, and when the external force on the handle structure 100 is removed, the handle structure 100 can automatically switch from the first working state to the initial state under the action of one of the elastic telescopic members 5. When the handle structure 100 is in a second working state under the action of an external force, and when the external force on the handle structure 100 is removed, the handle structure 100 can automatically switch from the second working state to the initial state under the action of the other elastic telescopic member 5. The user does not need to manually restore the position of the handle structure 100, making operation simpler and less strenuous. Moreover, the elastic telescopic member 5 can also provide a certain amount of moving resistance, so that the auxiliary wheel will only rotate when the user provides a certain forward or backward force, and will not rotate easily, thus improving stability.

[0071] Furthermore, the aforementioned elastic telescopic member 5 is provided in multiple sets. Each set of elastic telescopic members 5 includes two elastic telescopic members 5 arranged opposite each other along the axial direction of the trigger cylinder 3. The two elastic telescopic members 5 in the same set are respectively connected between the two ends of the trigger member in the axial direction and the handle body 1. The multiple sets of elastic telescopic members 5 are arranged circumferentially, so that the force on each side of the handle body 1 is more uniform during automatic reset, and it is not easy to shake. Preferably, there are two sets of elastic telescopic members, and the two sets of elastic telescopic members 5 are symmetrically arranged along the radial direction of the trigger cylinder 3. Therefore, setting the trigger member in a cylindrical shape can better ensure the stability of the handle body 1 when it moves. In the first working state, of the two elastic telescopic members in the same set, the upper elastic telescopic member 5 is in a compressed state, and the lower elastic telescopic member 5 is in a stretched state; in the second working state, of the two elastic telescopic members in the same set, the upper elastic telescopic member 5 is in a stretched state, and the lower elastic telescopic member 5 is in a compressed state, so that the handle body 1 can be reset better after the user removes the force.

[0072] Furthermore, the connecting portion 12 of the handle body 1 is generally cylindrical, with a partially thinned outer periphery to form a grooved area. The trigger cylinder 3 is fitted into the grooved area, and the cross-section of the grooved area is generally elliptical. The shape of the trigger cylinder 3 matches the shape of the grooved area, and it will not rotate relative to the handle body 1 after being fitted outside the grooved area. First protrusions are provided at both ends of the trigger cylinder 3 along the axial direction, and second protrusions are provided at both ends of the grooved area of ​​the handle body 1 along the axial direction. Each elastic telescopic member 5 is connected to the corresponding first and second protrusions.

[0073] The sensing element can be located on one side of the handle body 1 and on one side of the elastic telescopic member 5. The triggering element is located on one side of the first protrusion. Preferably, each triggering element includes a trigger protrusion 311 protruding from the inside of the handle 2, with the trigger protrusion 311 located between the handle 2 and the handle body 1. Each sensing element is configured as a mechanical micro switch, Hall effect switch, or photoelectric switch, etc. For example, when the sensing element is configured as a mechanical micro switch, moving the handle body 1 allows the mechanical micro switch to move as well. When one of the trigger protrusions 311 presses against the corresponding mechanical micro switch, the drive mechanism is activated, driving the auxiliary wheel to rotate. Furthermore, the trigger protrusion 311 has a chamfer in the direction of movement of the corresponding sensing element, allowing the mechanical micro switch to be better pressed by the trigger protrusion 311 to form a micro-motion, making the sensing element more sensitive and the triggering effect more obvious.

[0074] This utility model also provides a cleaning device, which includes a device body and the aforementioned handle structure 100. The handle 2 of the handle structure 100 is connected to the device body, so that the handle structure 100 can be better fixed to the device body for easy gripping and use by the user.

[0075] Furthermore, the main body of the device includes a floor brush structure, an auxiliary wheel rotatably mounted on the floor brush structure, and a drive mechanism connected to the auxiliary wheel. The drive mechanism can be a drive motor, and is electrically connected to a sensing unit on the handle structure 100. A controller can also be installed within the cleaning device. The controller is electrically connected to both the sensing unit and the drive mechanism. After being triggered by a triggering unit, the sensing unit emits a sensing signal. Upon receiving the sensing signal, the controller controls the drive motor to rotate forward or backward, thereby controlling the forward or reverse rotation of the auxiliary wheel. When the handle structure 100 is in the first working state, the drive mechanism drives the auxiliary wheel to rotate in a first direction; when the handle structure 100 is in the second working state, the drive mechanism drives the auxiliary wheel to rotate in a second direction. The first and second directions are opposite. The first direction represents the direction of rotation when the auxiliary wheel moves forward, and the second direction represents the direction of rotation when the auxiliary wheel moves backward. This allows for control of the auxiliary wheel's rotation by moving the handle structure 100, simplifying operation and making the cleaning device work more smoothly. The working principle of the auxiliary wheel's forward or backward movement has been described above and will not be repeated here.

[0076] This utility model also provides a cleaning system, which includes the aforementioned cleaning equipment and a base station, where the cleaning equipment can be placed. After the cleaning equipment is placed on the base station, the base station can be connected to the cleaning equipment. Through the base station, dirt stored in the cleaning equipment can be sucked into the base station or discharged into a sewage pipe, and / or the base station can also charge the cleaning equipment and / or clean the cleaning components on the cleaning equipment. Furthermore, the handle structure 100 of the cleaning equipment allows the auxiliary wheels to rotate when the cleaning equipment is placed on or removed from the base station, making it easier to place and remove, thus improving the user experience.

[0077] Obviously, the solutions described above are only a part of the solutions of this utility model, not all of them. Based on the solutions of this utility model, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the scope of protection of this utility model.
