Detailed Implementation

[0028] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings.

[0029] Combination Figure 1 , Figure 2 and Figure 3 As shown, this application embodiment provides a cleaning device, which can be a floor scrubber, vacuum cleaner, carpet cleaner, mite remover, etc. The cleaning device includes a handle 10, a detection device 11 disposed on the handle 10, a roller 20, an assist motor 30, and a controller 40 electrically connected to the detection device 11 and the assist motor 30.

[0030] The handle 10 includes a gripping part 101 and a connecting part 102. The gripping part 101 is for the user's hand to hold and contact, and the connecting part 102 is rigidly connected to the gripping part 101, with both moving in the same direction. A detection device 11 is used to detect the movement of the handle 10. The roller 20 contacts the surface to be cleaned when the cleaning equipment is in operation. Surfaces to be cleaned include carpets, floors, and bed surfaces. A power assist motor 30 is connected to the roller 20 and is used to drive the roller 20 to rotate. A controller 40 is electrically connected to the detection device 11 and the power assist motor 30, and is used to control the power assist motor 30 according to the movement of the handle 10, so that the power assist motor 30 drives the roller 20 to rotate.

[0031] Using the cleaning equipment provided in this application embodiment, the movement of the handle 10 of the cleaning equipment is detected by the detection device 11. The movement of the handle 10 can accurately reflect the current movement of the cleaning equipment. Based on this, the assist motor 30 is controlled to drive the roller 20 to rotate, which can achieve more accurate assist control, which helps to reduce the difficulty of operating the cleaning equipment and improve the user experience.

[0032] In addition, since the handle 10 is relatively far from the surface to be cleaned during use, using the movement of the handle 10 as the basis for the drive control of the assist motor 30 can avoid interference from complex surface conditions and optimize the accuracy of the assist control process.

[0033] Specifically, the movement of the handle 10 includes its direction of movement. The controller 40 controls the assist motor 30 to drive the roller 20 to rotate based on the movement of the handle 10. This includes the controller 40 controlling the assist motor 30 to drive the roller 20 to move in the same direction as the handle 10. That is, driving the roller 20 to move in the same direction as the overall movement of the cleaning equipment achieves a labor-saving effect and reduces the difficulty of operating the cleaning equipment.

[0034] In some embodiments, the detection device 11 is disposed inside the handle 10. Specifically, in conjunction with Figure 4 As shown, the handle 10 includes a housing for the user to grip and a receiving cavity 100 defined by the housing, with the detection device 11 disposed within the receiving cavity 100. Thus, the impact of adding the detection device 11 on the structure is only reflected inside the handle 10, and does not affect the daily use of the cleaning equipment, ensuring a good user experience while accurately monitoring movement. Figure 5 As shown, in different embodiments, the receiving cavity 100 may be disposed at different positions within the handle 10, for example... Figure 5 Positions A, B, C, or D are used as examples. It should be noted that positions A, B, C, or D are used as examples only and do not specify any particular shape, location, volume, or number of the receiving cavity 100 within the handle 10.

[0035] Combination Figures 6 to 10 The following provides a more detailed explanation of the setup of the detection device 11.

[0036] The detection device 11 includes a movable component 110 and a direction monitoring device. The movable component 110 is movably disposed within the receiving cavity 100 and is capable of relative displacement with the inner wall of the receiving cavity 100. During implementation, a space is maintained between the receiving cavity 100 and the movable component 110 to provide space for the movable component 110 to move within the receiving cavity 100. The direction monitoring device is used to monitor the displacement direction of the movable component 110 relative to the inner wall of the receiving cavity 100. The controller 40 is electrically connected to the direction monitoring device, and the controller 40 is used to control the assist motor 30 to drive the roller 20 to rotate in the opposite direction to the displacement of the movable component 110.

[0037] When the user changes the movement state of the cleaning equipment via the handle 10, the force applied by the user acts directly on the handle 10, causing the other parts of the cleaning equipment directly connected to the handle 10 to change their movement state. Since the moving part 110 and the inner wall of the receiving cavity 100 are two relatively independent parts capable of relative displacement, when the movement state of the inner wall of the handle 10 changes, due to its own inertia, the detection device 11 will maintain its original movement state for a short time, causing relative displacement between the detection device 11 and the receiving cavity 100. Furthermore, the displacement direction of the detection device 11 relative to the inner wall of the receiving cavity 100 is opposite to the overall forward direction of the cleaning equipment. Therefore, based on the displacement direction of the moving part 110, which is movably installed within the receiving cavity 100, the overall forward direction of the cleaning equipment can be accurately determined. The controller 40 controls the assist motor 30 to drive the roller 20 to rotate in the opposite direction to the displacement direction of the moving part 110, which helps to synchronize the direction of the roller 20 with the moving direction of the cleaning equipment, thus providing assistance.

[0038] In some embodiments, the receiving cavity 100 is a cube, and the bottom wall of the receiving cavity 100 is horizontal. The movable member 110 can generate relative displacement with respect to the bottom wall of the receiving cavity 100. Considering that the cleaning device may be in different forms in the use state and the storage state, it should be noted here that the horizontal setting of the bottom wall of the receiving cavity 100 specifically means that the bottom wall of the receiving cavity 100 remains horizontal when the cleaning device is in the normal use state.

[0039] Combination Figure 6 As shown, in some embodiments, a slide rail 12 is provided within the receiving cavity 100. The moving member 110 includes a slider, which is slidably connected to the slide rail 12. Using the slider as the moving member 110 and providing the slide rail 12 can limit the movement path of the slider, which is beneficial for achieving more accurate movement direction determination, thereby improving the accuracy of the rotation direction control of the roller 20.

[0040] Specifically, in some embodiments, the extension direction of the slide rail 12 intersects the rotation axis of the roller 20. This further limits the movement path of the slider, preventing it from moving in other directions due to the instability of the cleaning device's movement process. This improves the accuracy of judging the slider's movement direction, thereby improving the accuracy of controlling the rotation direction of the roller 20. More specifically, in some embodiments, the slide rail 12 is arranged horizontally and perpendicular to the rotation axis of the roller 20. Considering that the cleaning device may be in different forms in its use and storage states, it should be noted that the slide rail 12 being arranged horizontally specifically means that the slide rail 12 is horizontal when the cleaning device is in use.

[0041] Combination Figure 7As shown, in some embodiments, the detection device 11 further includes an elastic connector 114 connected between the movable member 110 and the inner wall of the receiving cavity 100. The initial position of the movable member 110 within the receiving cavity 100 is taken when both the movable member 110 and the elastic connector 114 are relatively stationary. When the motion state of the cleaning equipment changes, the movable member 110 moves relative to the inner wall of the receiving cavity 100 due to the inertia of maintaining its original motion state, and the elastic connector 114 is stretched or compressed to a certain extent. When the motion state of the cleaning equipment returns to stability, the elastic potential energy of the deformed elastic connector 114 is converted into the kinetic energy of the movable member 110, causing the movable member 110 to return to its initial position, thus resetting the movable member 110. This avoids situations where the movable member 110 moves within the receiving cavity 100, limiting its subsequent movement distance or even touching the side wall of the receiving cavity 100 and preventing further movement. This improves the accuracy of controlling the rotation direction of the roller 20 through the displacement direction of the movable member 110. In some embodiments, the elastic connector 114 is a spring.

[0042] In some embodiments, the extending direction of the elastic connector 114 intersects the rotation axis of the roller 20. The roller 20 rotates about its rotation axis, and the direction of the rotation axis of the roller 20 is perpendicular or nearly perpendicular to the common moving direction of the moving member 110. When the moving member 110 moves, the elastic connector 114 is stretched in the moving direction of the moving member 110. Here, the extending direction of the elastic connector 114 intersects the rotation axis of the roller 20 rather than being parallel to it, which helps to avoid overstretching the elastic connector 114 in a direction perpendicular to its extending direction, improves the uniformity of the force on the elastic connector 14, and reduces the risk of damage to the elastic connector 14. Specifically, in some embodiments, the elastic connector 114 is arranged horizontally and perpendicular to the rotation axis of the roller 20. In this way, the moving path of the moving member 110 is parallel to the extending direction of the elastic connector 114, and the force on the elastic connector 114 is more uniform, which helps to improve the reset effect. It also helps to save space.

[0043] In some embodiments, the elastic connector 114 includes a first elastic connector 1141 and a second elastic connector 1142. The first elastic connector 1141 and the second elastic connector 1142 are arranged collinearly with the movable member 110 and are respectively connected to both sides of the movable member 110. Thus, the first elastic connector 1141, the movable member 110, and the second elastic connector 1142 are sequentially connected along the same straight line between the inner walls of both sides of the receiving cavity 100. After the movable member 110 moves in either direction towards the first elastic connector 1141 or towards the second elastic connector 1142, it is reset by the traction of the elastic connectors 114 distributed on both sides of the movable member 110. This provides a more stable reset effect compared to reset by only one side of the elastic connector 114. In other embodiments, the number of elastic connectors 114 can also be set to 1 or more than 2, depending on different actual needs.

[0044] The specific implementation of the aforementioned direction monitoring device will now be described.

[0045] Combination Figure 8 As shown, in some embodiments, the direction monitoring device includes a displacement sensor 111. This displacement sensor 111 is used to detect the displacement direction of the moving member 110 relative to the inner wall of the receiving cavity 100. Specifically, the displacement sensor 111 is used to detect the displacement direction of the moving member 110 relative to the bottom surface of the receiving cavity 100. Thus, by using the displacement sensor 111, accurate detection of the movement direction of the moving member 110 can be achieved, thereby improving the accuracy of the steering control of the roller 20.

[0046] In some embodiments, the displacement sensor 111 is disposed on the slider and moves synchronously with the slider.

[0047] In some embodiments, the orientation monitoring device includes a switch 113.

[0048] Combination Figure 9As shown, the movable member 110, which cooperates with the switch member 113, is provided with a contact 112. The switch member 113 is disposed on the movement path of the contact 112 of the movable member 110, and the switching state of the switch member 113 changes with the contact state of the contact 112. The controller 40 is electrically connected to the switch member 113 and is used to control the auxiliary motor 30 according to the switching state of the switch member 113 to drive the roller 20 to rotate. As can be seen from the foregoing analysis, when the movement state of the cleaning equipment changes, the position of the movable member 110 within the receiving cavity 100 changes. Since the switch member 113 is disposed on the movement path of the contact 112 of the movable member 110, the contact state between the movable member 110 and the switch member 113 changes when the movable member 110 moves, for example, from no contact to contact, or from contact to no contact. The contact state between contact 112 and switch 113 affects the switching state of switch 113. Based on the switching state of switch 113, the movement of movable member 110 within receiving cavity 100 can be determined, thereby determining the displacement direction of movable member 110 relative to the inner wall of receiving cavity 100. This allows for accurate determination of the displacement direction of movable member 110 relative to the inner wall of receiving cavity 100, which helps ensure the accuracy of the final roller 20 rotation control. Furthermore, placing contact 112, rather than switch 113, on movable member 110 reduces the impact on the weight of movable member 110, thereby reducing the impact on the movement state of movable member 110 and improving the accuracy of determining the displacement direction of movable member 110.

[0049] Among them, the switching element 113 is a micro switch. The micro switch has a small size and is suitable for the application environment of the receiving cavity 100 inside the handle 10 in this application. At the same time, the micro switch has high sensitivity and can change the switching state according to the tiny action of contacting the contact 112, so as to realize the contact state recognition of the contact 112.

[0050] Here, the configuration of the switch 113 is described in more detail. In some embodiments, the switch 113 includes a first switch and a second switch. The first switch and the second switch are respectively disposed on both sides of the moving member 110 along the moving direction of the moving member 110, and both the first switch and the second switch are electrically connected to the controller 40. The controller 40 can determine whether the displacement direction of the moving member 110 is closer to the first switch or closer to the second switch based on the on / off state of the first switch and the second switch. The controller 40 controls the power assist motor 30 to drive the roller 20 to move in the opposite direction to the displacement direction of the moving member 110, thereby achieving accurate control of the steering of the roller 20.

[0051] In some implementations, a switch 113 is provided only on one side of the moving member 110. Specifically, the switch 113 includes a first switch, which is disposed on one side of the moving member 110 along the moving direction of the moving member 110. If the switch status of the first switch indicates that the first switch is in contact with the moving member 110, then the moving direction of the moving member 110 is determined to be towards the first switch; if the switch status of the first switch indicates that the first switch is not in contact with the moving member 110, then the moving direction of the moving member 110 is determined to be away from the first switch, and this is used as a control reference. In this way, only one switch 113 is needed to determine the displacement direction of the moving member 110, which can balance structural simplification and the accuracy of controlling the rotation direction of the roller 20.

[0052] Combination Figure 10 As shown, in some embodiments, the elastic connector 114, cooperating with the switch 113, is provided with a contact 112. The switch 113 is disposed on the moving path of the contact 112 of the elastic connector 114, and the switching state of the switch 113 changes with the contact state of the contact 112. The controller 40 is electrically connected to the switch 113 and is used to control the assist motor 30 according to the switching state of the switch 113 to drive the roller 20 to rotate. The contact 112 can be disposed at any position in the elastic connector 114 except for the contact point 112 with the inner wall of the receiving cavity 100. The moving member 110 is directly connected to the elastic connector 114, and when the moving member 110 moves within the receiving cavity 100, it causes the elastic connector 114 to stretch or compress. Except for the connection point between the elastic connector 114 and the inner wall of the receiving cavity 100, any point within the elastic connector 114 will be displaced. Since the switch 113 is positioned on the moving path of the contact 112 of the elastic connector 114, the elastic connector 114 is stretched or compressed. This causes the contact 112 to shift within the receiving cavity 100, changing its contact state with the switch 113 and altering the switching state of the switch 113. Based on the switching state of the switch 113, the movement of the moving member 110 within the receiving cavity 100 can be determined, thereby determining the displacement direction of the moving member 110 relative to the receiving cavity 100. This allows for accurate determination of the displacement direction of the moving member 110 relative to the inner wall of the receiving cavity 100, which helps ensure the accuracy of the final roller 20 control.

[0053] In some embodiments, the switching element 113 includes a third switching element and a fourth switching element. The third and fourth switching elements are respectively disposed on both sides of the same contact 112 in its original state along the movement path of the contact 112, and both the third and fourth switching elements are electrically connected to the controller 40. That is, the third switching element, the contact 112 disposed on the elastic connector 114, and the fourth switching element are collinearly disposed. The controller 40 can determine whether the elastic connector 114 is compressed or stretched based on the switching state of the third and fourth switching elements, and thus determine the displacement direction of the moving element 110 in the receiving cavity 100. The controller 40 controls the assist motor 30 to drive the roller 20 to move in the opposite direction to the displacement direction of the moving element 110, so as to achieve accurate control of the direction of rotation of the roller 20.

[0054] In some embodiments, a switch 113 is provided only on one side of the contact 112 in its original state. Specifically, the switch 113 includes a third switch, which is disposed on one side of the movable member 110 along the moving direction of the contact 112. The controller 40 is electrically connected to the third switch, determines the displacement direction of the movable member 110 relative to the inner wall of the receiving cavity 100 according to the switching state of the third switch, and controls the assist motor 30 to drive the roller 20 to rotate in the opposite direction to the displacement direction of the movable member 110. Corresponding to different positional arrangements between the switch 113 and the contact 112, a change in the state of the switch 113 indicates a different displacement direction of the movable member 110. In the original state, when the contact 112 is disposed between the movable member 110 and the third switch, if the switching state of the third switch changes, it means that the elastic connecting member 114 with the contact 112 is compressed, and the moving direction of the movable member 110 within the receiving cavity 100, i.e., the displacement direction of the movable member 110, points towards the side closer to the contact 112. In the original state, with the third switch positioned between contact 112 and moving member 110, if the switching state of the third switch changes, it indicates that the elastic connecting member 114 with contact 112 is stretched. The direction of movement of moving member 110 within the receiving cavity 100, i.e., the displacement direction of moving member 110, points away from contact 112. During implementation, corresponding control logic can be set according to different relative positions between switch member 113 and contact 112. In this way, only one switch member 113 is needed to determine the displacement direction of moving member 110, achieving both structural simplification and accurate control of the rotation direction of roller 20.

[0055] It should be noted that this description of a feasible implementation where the contact 112 is provided on the elastic connector 114 does not imply that the position of the contact 112 changes entirely depending on whether the elastic connector 114 is present or not. When the detection device 11 includes the elastic connector 114, the contact 112 can also be located at the moving member 110.

Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include at least one of that feature.
