[0006] The magnetic sensing component is also used to determine the rotation angle of the swing arm based on changes in the magnetic field.
[0007] The magnetic sensing component includes: a magnetic element embedded in a first mounting groove; and a magnetic sensing body positioned opposite and spaced apart from the magnetic element. The magnetic element generates a magnetic field, and the magnetic sensing body detects the relative angle between itself and the rotation axis based on changes in the magnetic field, and determines the rotation angle of the swing arm based on the relative angle.
[0008] The first mounting groove is located on the side of the rotating shaft away from the drive body, and the end of the rotating shaft away from the drive body extends toward the first mounting groove and is connected to the magnetic component.
[0009] The first mounting groove has a slot, which is located on the side of the first mounting groove away from the shaft hole. The side of the magnetic component facing away from the shaft hole is exposed in the slot, and the slot is set towards the magnetic body.
[0010] The detection end and magnetic components of the magnetic sensor are coaxially arranged with the rotation axis along the center line perpendicular to the north and south poles.
[0011] The swing arm has a protrusion on the side facing away from the drive body, the protrusion extends in a direction away from the drive body, and at least part of the first mounting groove and shaft hole are formed on the protrusion.
[0012] The cleaning device includes a first housing and a second housing connected to each other. A first receiving cavity and a first opening communicating with the first receiving cavity are formed between the first housing and the second housing. One end of the swing arm with a protrusion is rotatably disposed in the first receiving cavity, and the other end extends out from the first opening. The first housing has a second mounting groove communicating with the first receiving cavity. When the end of the swing arm with the protrusion is disposed in the first receiving cavity, the second mounting groove is correspondingly disposed with the protrusion, and the magnetic induction body is disposed in the second mounting groove.
[0013] The protrusion is inserted into the second mounting groove.

[0017] The advantages of the embodiments of this application, which differ from the prior art, are as follows: This application provides a cleaning device, which includes a swing arm, a drive assembly, and a magnetic sensing assembly. The swing arm is provided with a shaft hole and a first mounting groove that connects to the shaft hole. The drive assembly includes a drive body and a rotating shaft connected to the drive body, with one end of the rotating shaft disposed in the shaft hole. The magnetic sensing assembly is at least partially disposed in the first mounting groove. The drive body drives the swing arm to rotate through the rotating shaft, and the magnetic sensing assembly is used to generate a magnetic field, which changes with the rotation of the rotating shaft. By setting a shaft hole and a first mounting groove connecting the shaft hole on the swing arm, one end of the rotating shaft of the drive component is placed in the shaft hole, and at least a part of the magnetic sensing component is placed in the first mounting groove. This allows at least a part of the magnetic sensing component to rotate synchronously as the drive body drives the swing arm to rotate through the rotating shaft. The magnetic field of the magnetic sensing component can change with the rotation of the rotating shaft. When the swing arm is obstructed, such as by a collision or interference, the swing arm will shake or vibrate, causing a change in the magnetic field of the magnetic sensing component. The magnetic sensing component can determine whether the swing arm is obstructed based on the change in the magnetic field, thereby detecting the obstruction of the swing arm. This allows the cleaning equipment to take timely measures, such as changing the swing arm's movement posture or prompting the user to remove the obstruction. This not only reduces the risk of damage or malfunction of the swing arm due to continuous obstruction, thus improving the service life of the cleaning equipment, but also allows the cleaning equipment to quickly get rid of the obstruction and continue cleaning operations, effectively improving the cleaning effect of the cleaning equipment.

[0032] Please see Figure 1 , Figure 1 This is a structural schematic diagram of the cleaning equipment provided in this application. This application provides a cleaning equipment 1000. The cleaning equipment 1000 includes, but is not limited to, a sweeping robot, a floor scrubber, or a mopping robot. The cleaning equipment 1000 includes a swing arm 10 and a drive assembly 20. The swing arm 10 is used to connect components such as a mop and side brushes. The drive assembly 20 is used to control the movement of the swing arm 10, enabling the swing arm 10 to move the mop, side brushes, and other components under the drive of the drive assembly 20. Driven by the swing arm 10, the mop, side brushes, and other components can clean areas such as floors, walls, and corners, expanding the cleaning range of the cleaning equipment 1000. Furthermore, the drive assembly 20 can flexibly change the direction of the swing arm 10 to avoid obstacles or perform edge cleaning along walls, thereby effectively cleaning complex areas and improving the cleaning effect of the cleaning equipment 1000.
[0033] Please refer to the following: Figure 2 , Figure 2 This is a schematic diagram of the structure of the drive assembly and the swing arm of the cleaning equipment provided in this application. The swing arm 10 has a shaft hole 111 and a first mounting groove 112 communicating with the shaft hole 111. The shaft hole 111 is located on the side of the first mounting groove 112 near the drive assembly 20. The drive assembly 20 includes a drive body 21 and a rotating shaft 22 connected to the drive body 21, with one end of the rotating shaft 22 disposed in the shaft hole 111. The drive body 21 drives the rotating shaft 22 to rotate, so that the rotating shaft 22 drives the swing arm 10 and the mop, side brush and other components on the swing arm 10 to rotate. In this process, the driving force generated by the drive body 21 is transmitted to the swing arm 10 through the rotating shaft 22, and then to the mop, side brush and other components through the swing arm 10, so that the mop, side brush and other components can move flexibly, and the cleaning equipment 1000 can efficiently complete the cleaning task. The drive body 21 can be a motor, an electric cylinder or a pneumatic cylinder, but is not limited to these.
[0034] The cleaning device 1000 also includes a magnetic sensing component. The magnetic sensing component is at least partially disposed within the first mounting slot 112. The drive body 21 drives the swing arm 10 to rotate via a rotating shaft 22, and the magnetic sensing component generates a magnetic field that changes with the rotation of the rotating shaft 22.
[0035] The changes in the magnetic field of the magnetic sensing component include changes in magnetic field strength and magnetic field direction. By embedding at least a portion of the magnetic sensing component in the first mounting groove 112, the first mounting groove 112 can effectively position at least a portion of the magnetic sensing component, so that when the driving body 21 drives the swing arm 10 to rotate via the rotating shaft 22, at least a portion of the magnetic sensing component will also rotate synchronously, and the magnetic field of the magnetic sensing component can change with the rotation of the rotating shaft 22.
[0036] In some embodiments, if the swing arm 10 is obstructed during its rotation, for example, when the swing arm 10 interferes with or collides with other objects, the swing arm 10 will sway or vibrate and produce a small angle of deflection. The magnetic field strength and magnetic field direction of the magnetic sensing component will also change due to the swaying or vibration of the swing arm 10. At this time, the change in the magnetic field strength and magnetic field direction of the magnetic sensing component is different from the change in the magnetic field strength and magnetic field direction of the magnetic sensing component during the normal rotation of the swing arm 10. At the same time, the magnetic sensing component can also determine whether the swing arm 10 is obstructed based on the change in the magnetic field strength and magnetic field direction.
[0037] In some embodiments, the cleaning device 1000 further includes a processor, with a magnetic sensing component connected to the processor. When the magnetic sensing component detects obstruction of the swing arm 10, it sends an abnormal signal to the processor. In response to the abnormal signal, the processor controls the drive component 20 to change the swing arm 10's posture, for example, by reversing the swing arm 10, so that the swing arm 10 automatically avoids the obstacle, allowing the cleaning device 1000 to continue cleaning operations, thereby improving the cleaning efficiency and effectiveness of the cleaning device 1000. In other embodiments, when the magnetic sensing component detects obstruction of the swing arm 10 and sends an abnormal signal, the processor controls the drive body 21 to close, stopping the swing arm 10 from rotating. Simultaneously, the processor also controls a prompting component (not shown) on the cleaning device 1000 to activate, prompting the user to remove the obstruction so that the cleaning device 1000 can continue cleaning operations. The prompting component can be a display screen, LED lights, speakers, vibrators, etc. The prompting information can be text or images displayed on the screen; light or flashing from LED lights; sound played from speakers; vibration generated by the vibrator, etc.
[0038] By providing a shaft hole 111 and a first mounting groove 112 connecting the shaft hole 111 on the swing arm 10, one end of the rotating shaft 22 of the drive assembly 20 is disposed in the shaft hole 111, and at least a portion of the magnetic sensing assembly is disposed in the first mounting groove 112. This allows at least a portion of the magnetic sensing assembly to rotate synchronously as the drive body 21 drives the swing arm 10 to rotate via the rotating shaft 22. Furthermore, the magnetic field of the magnetic sensing assembly can change with the rotation of the rotating shaft. When the swing arm 10 is obstructed, such as by a collision or interference, the swing arm 10 will shake or vibrate, causing magnetic induction. When the magnetic field of the component changes, the magnetic sensing component can determine whether the swing arm 10 is obstructed based on the change in the magnetic field. This allows the cleaning equipment 1000 to detect the obstruction of the swing arm 10, so that it can take timely measures such as changing the movement posture of the swing arm 10 or prompting the user to remove the obstruction. This not only reduces the risk of damage or malfunction of the swing arm 10 due to continuous obstruction, thereby increasing the service life of the cleaning equipment 1000, but also enables the cleaning equipment 1000 to quickly get rid of the obstruction and continue cleaning operations, effectively improving the cleaning effect of the cleaning equipment 1000.
[0039] In some embodiments, the magnetic sensing component is also used to determine the rotation angle of the swing arm 10 based on changes in the magnetic field.
[0040] The magnetic sensing component can determine the rotation angle of the swing arm 10 based on the change of the magnetic field, and determine the position of the swing arm 10 based on the rotation angle of the swing arm 10, thereby determining whether the swing arm 10 has rotated to a specific position. This enables the detection of the swing arm 10's position without the need for a separate position detection sensor, thus effectively reducing the production cost of the cleaning equipment.
[0041] In some embodiments, please continue reading Figure 2 The magnetic sensing component includes a magnetic element 30 and a magnetic sensing body. The magnetic element 30 is embedded in the first mounting groove 112. The magnetic sensing body and the magnetic element 30 are positioned opposite each other and spaced apart. The magnetic element 30 is used to generate a magnetic field, and the magnetic sensing body is used to detect the relative angle between itself and the rotation axis 22 based on the change in the magnetic field, and to determine the rotation angle of the swing arm 10 based on the relative angle between the magnetic sensing body and the rotation axis 22.
[0042] In some embodiments, the magnetic element 30 can be fixed to the end of the rotating shaft 22 away from the driving body 21, so that the magnetic element 30 can rotate with the rotating shaft 22 during the rotation of the swing arm 10 driven by the rotating shaft 22; alternatively, the magnetic element 30 can be spaced apart from the rotating shaft 22, so that the magnetic element 30 can rotate with the swing arm 10 during the rotation of the rotating shaft 22. The magnetic sensing body can be disposed on the side of the magnetic element 30 facing away from the rotating shaft 22, and is opposite to and spaced apart from the magnetic element 30.
[0043] During the rotation of the swing arm 10 and magnetic component 30 via the rotating shaft 22, driven by the main drive 21, the magnetic field strength and direction of the magnetic component 30 change. The magnetic sensor can detect the magnetic field strength and direction of the magnetic component 30 in real time and determine the rotation angle of the swing arm 10 based on these changes. The magnetic sensor detects the relative angle between itself and the rotating shaft 22 based on the changes in the magnetic field of the magnetic component 30, and determines the rotation angle of the swing arm 10 accordingly. This fast response effectively improves the detection accuracy of the swing arm 10's rotation angle. The magnetic sensor can be an angle sensor or a rotating magnetic field sensor, but is not limited to these.
[0044] In some embodiments, please continue reading Figure 2 The first mounting groove 112 is located on the side of the rotating shaft 22 away from the drive body 21. The end of the rotating shaft 22 away from the drive body 21 extends toward the first mounting groove 112 and is connected to the magnetic component 30.
[0045] Specifically, the magnetic component 30 is embedded in the first mounting groove 112 and connected to the end of the rotating shaft 22 away from the driving body 21. By connecting the magnetic component 30 to the end of the rotating shaft 22 away from the driving body 21, it can be ensured that the rotation of the magnetic component 30 is completely synchronized with the rotation of the rotating shaft 22, and the magnetic field strength and direction of the magnetic component 30 can change with the rotation of the rotating shaft 22. This allows the magnetic field strength and direction of the magnetic component 30 to accurately reflect the position of the swing arm 10, the rotation path of the swing arm 10, and the obstruction encountered by the swing arm 10 during rotation, thus facilitating accurate detection of the rotation process of the swing arm 10.
[0046] In some embodiments, please continue reading Figure 2 The first mounting groove 112 has a slot 112a, which is located on the side of the first mounting groove 112 away from the shaft hole 111. The side of the magnetic component 30 facing away from the shaft hole 111 is exposed in the slot 112a, which is oriented towards the magnetic body.
[0047] The magnetic element 30 may be completely disposed within the first mounting groove 112, and the magnetic element 30 may not extend beyond the groove opening 112a or be flush with the groove opening 112a; or at least a portion of the magnetic element 30 may also protrude from the groove opening 112a.
[0048] By exposing the side of the magnetic component 30 facing away from the shaft hole 111 in the slot 112a, and with the slot 112a facing the magnetic sensing body, there are no obstructions between the magnetic component 30 and the sensing component. This allows the magnetic sensing body to accurately detect changes in the magnetic field strength and direction of the magnetic component 30. Consequently, the magnetic sensing body can quickly and accurately determine the rotation angle of the swing arm 10, thereby improving the detection accuracy and speed of the magnetic sensing body in detecting the rotation angle of the swing arm 10.
[0049] Please refer to the following: Figures 3 to 4 , Figure 3 This is a schematic diagram of an embodiment of the magnetic component of the cleaning equipment provided in this application cooperating with the swing arm; Figure 4 yes Figure 3 Enlarged view of part A in the figure. The inner wall of the first mounting groove 112 is provided with ribs 121, which are interference-fitted with the magnetic component 30; and / or an adhesive component (not shown) is provided between the inner wall of the first mounting groove 112 and the magnetic component 30.
[0050] In some embodiments, the inner wall of the first mounting groove 112 is provided with ribs 121, and the ribs 121 are interference-fitted with the magnetic component 30. In other embodiments, an adhesive is provided between the inner wall of the first mounting groove 112 and the magnetic component 30, and the magnetic component 30 is fixed in the first mounting groove 112 by the adhesive. In other embodiments, the inner wall of the first mounting groove 112 is provided with ribs 121, and an adhesive is also provided between the inner wall of the first mounting groove 112 and the magnetic component 30.
[0051] The adhesive can be a solvent-based adhesive, a water-based adhesive, an epoxy resin adhesive, or an organosilicon adhesive, but is not limited to these.
[0052] By providing ribs 121 on the inner wall of the first mounting groove 112 and interfering with the magnetic component 30 through the ribs 121, the friction and mechanical engagement force between the magnetic component 30 and the first mounting groove 112 can be increased, effectively improving the positioning and fixing effect of the magnetic component 30. Simultaneously, the ribs 121 also enhance the vibration resistance of the magnetic component 30, further enabling the magnetic field strength and direction of the magnetic component 30 to accurately reflect the position of the swing arm 10, the rotation path of the swing arm 10, and the obstruction encountered by the swing arm 10 during rotation. By providing an adhesive between the inner wall of the first mounting groove 112 and the magnetic component 30, the magnetic component 30 can be fixed within the first mounting groove 112, effectively improving the positioning and fixing effect of the magnetic component 30.
[0053] Please refer to the following: Figures 5 to 6 , Figure 5 This is a schematic diagram of another embodiment of the magnetic component of the cleaning device provided in this application cooperating with the swing arm; Figure 6 yes Figure 5 Enlarged view of part B in the figure. The magnetic component 30 can also be installed in the first mounting groove 112 by injection molding.
[0054] In some embodiments, the detection end of the magnetic induction body and the magnetic element 30 are coaxially arranged with the rotation axis 22 along a center line perpendicular to the north and south poles.
[0055] The detection end of the magnetic induction body is used to detect changes in the magnetic field strength and direction of the magnetic component 30.
[0056] By aligning the detection end of the magnetic sensor and the magnetic component 30 coaxially with the rotation axis 22 along a centerline perpendicular to the north and south poles, the detection errors caused by positional deviations are reduced when the rotation axis 22 drives the swing arm 10 and the magnetic component 30 to rotate. This not only allows the magnetic field strength and direction of the magnetic component 30 to accurately reflect the position of the swing arm 10, its rotation path, and the obstruction encountered during rotation, but also makes the detection of the magnetic field strength and direction of the magnetic component 30 by the magnetic sensor more precise, thus improving the accuracy and stability of the detection results. Furthermore, it ensures that the detection end of the magnetic sensor is always in a relatively stable magnetic field environment, reducing the influence of external factors on the detection accuracy of the magnetic sensor, further improving the accuracy and stability of the detection results.
[0057] In some embodiments, a protrusion 11 is formed on the side of the swing arm 10 facing away from the drive body 21. The protrusion 11 extends in a direction away from the drive body 21, and at least a portion of the first mounting groove 112 and the shaft hole 111 are formed on the protrusion 11.
[0058] The protrusion 11 is integrally formed on the side of the swing arm 10 facing away from the drive body 21. The first mounting groove 112 is completely located inside the protrusion 11, and the groove opening 112a of the first mounting groove 112 is located on the end face of the protrusion 11 facing away from the drive body 21.
[0059] In some embodiments, the interior of the swing arm 10 may be a hollow structure, with at least a portion of the shaft hole 111 formed in the protrusion 11, and the other portion of the shaft hole 111 located on the side of the swing arm 10 near the drive body 21, penetrating the surface of the swing arm 10 facing the drive body 21 and the interior of the swing arm 10. The shaft hole 111 formed in the protrusion 11 and the shaft hole 111 formed on the side of the swing arm 10 near the drive body 21 are coaxially arranged. Alternatively, the interior of the swing arm 10 may be provided with a fixed shaft (not shown), which is supported between the side of the swing arm 10 near the drive body 21 and the side of the swing arm 10 away from the drive body 21. At least a portion of the shaft hole 111 is formed in the protrusion 11, and the other portion of the shaft hole 111 may be located inside the fixed shaft and extend to the surface of the swing arm 10 facing the drive body 21. The shaft hole 111 formed in the protrusion 11 and the shaft hole 111 formed on the fixed shaft are coaxially arranged.
[0060] The shaft hole 111 of the swing arm 10 serves to fix the rotating shaft 22. By extending the protrusion 11 away from the drive body 21 and forming at least a portion of the shaft hole 111 in the protrusion 11, the depth of the shaft hole 111 can be increased, thereby improving the stability of the rotating shaft 22. This prevents the rotating shaft 22 from interfering with the magnetic field strength and direction of the magnetic component 30 due to instability during rotation, effectively improving the accuracy of the detection results of the magnetic sensing body. By forming at least a portion of the first mounting groove 112 and the shaft hole 111 in the protrusion 11, the coaxiality of the rotating shaft 22 and the magnetic component 30 along the center line perpendicular to the north and south poles can be effectively improved, further enhancing the accuracy of the detection results of the magnetic sensing body.
[0061] Please refer to the following: Figures 7 to 8 , Figure 7 This is a schematic diagram of the structure of the first housing and the second housing of the cleaning equipment provided in this application. Figure 8This is a schematic diagram of the structure of the cleaning device 1000 provided in this application, including the swing arm, the first housing, and the second housing in cooperation. The cleaning device 1000 includes a first housing 40 and a second housing 50 connected to each other. A first receiving cavity 41 and a first opening 41a communicating with the first receiving cavity 41 are formed between the first housing 40 and the second housing 50. One end of the swing arm 10 with a protrusion 11 is rotatably disposed in the first receiving cavity 41, and the other end extends out from the first opening 41a. The first housing 40 has a second mounting groove 42 communicating with the first receiving cavity 41. When the end of the swing arm 10 with the protrusion 11 is disposed in the first receiving cavity 41, the second mounting groove 42 is correspondingly disposed with the protrusion 11, and the magnetic body is disposed in the second mounting groove 42.
[0062] The first housing 40 and the second housing 50 can serve as the basic carriers for the swing arm 10, providing support and protection for the swing arm 10. Meanwhile, by rotatably placing one end of the swing arm 10 with the protrusion 11 inside the first receiving cavity 41 and extending the other end from the first opening 41a, the first opening can limit the movement of the swing arm 10, enabling the swing arm 10 to have a stable rotation trajectory for effective cleaning of the area to be cleaned.
[0063] The arrangement direction of the first housing 40 and the second housing 50 is parallel to the axial direction of the rotation shaft 22, and the first housing 40 is located on the side of the second housing 50 away from the drive body 21. By setting the magnetic component 30 in the first mounting groove 112 of the protrusion 11 and setting the magnetic sensing body in the second mounting groove 42, and when the end of the swing arm 10 with the protrusion 11 is set in the first receiving cavity 41, the second mounting groove 42 is correspondingly set with the protrusion 11, which helps to improve the coaxiality of the detection end of the magnetic sensing body and the magnetic component 30 along the center line perpendicular to the north and south poles, and can improve the accuracy of the detection result of the magnetic sensing body.
[0064] The first housing 40 and the second housing 50 can be an integrally formed structure; or, the first housing 40 and the second housing 50 can be a separate structure, and the first housing 40 and the second housing 50 can be fixed together by means of bolt connection, rivet connection, snap connection or adhesive bonding.
[0065] In some embodiments, the protrusion 11 is inserted into the second mounting groove 42.
[0066] When the protrusion 11 is inserted into the second mounting groove 42, the magnetic component 30 is opposite to and spaced apart from the magnetic body.
[0067] The overall shape of the second mounting groove 42 can be adapted to the shape of the protrusion 11 on the swing arm 10, or the shape of the end of the second mounting groove 42 near the first receiving cavity 41 can be adapted to the shape of the protrusion 11 on the swing arm 10, and the size of the second mounting groove 42 is larger than the size of the protrusion 11, so that the protrusion 11 can be inserted into the second mounting groove 42.
[0068] By inserting the protrusion 11 into the second mounting groove 42, the distance between the magnetic component 30 and the magnetic sensing body can be reduced, so that the magnetic sensing body is located within a better detection range. This can increase the intensity of the magnetic field signal transmitted from the magnetic component 30 to the magnetic sensing body, thereby improving the detection accuracy of the magnetic sensing body. At the same time, it can also reduce the attenuation of the magnetic field signal of the magnetic component 30, so that the magnetic sensing body can respond to changes in the magnetic field more quickly, thereby improving the response speed of the magnetic sensing body.
[0069] In some embodiments, the second housing 50 has a second opening 50a communicating with the first receiving cavity 41, and the swing arm 10 has a rotating part 13 formed on the side of the protrusion 11 facing the second housing 50. The rotating part 13 is inserted into the second opening 50a from the first receiving cavity 41. The rotating part 13 has a second receiving cavity 131 communicating with the shaft hole 111, and the drive body 21 is disposed in the second receiving cavity 131.
[0070] By inserting the rotating part 13 from the first receiving cavity 41 into the second opening 50a, the rotating part 13 can be rotatably connected to the second opening 50a so that when the drive assembly 20 drives the rocker arm 10 to rotate, the rotating part 13 can rotate relative to the second housing 50. For example, a circumferential second slide groove (not shown) can be provided on one of the edges of the rotating part 13 and the second opening 50a, and a slide rail adapted to the second slide groove can be provided on the other edge of the rotating part 13 and the second opening 50a. When the drive assembly 20 drives the rocker arm 10 to rotate, the rotating part 13 rotates relative to the second housing 50 through the second slide groove and the slide rail.
[0071] In some embodiments, the protrusion 11 of the swing arm 10 is inserted into the second mounting groove 42, and the protrusion 11 can be rotatably disposed in the second mounting groove 42 so that when the drive assembly 20 drives the swing arm 10 to rotate, the protrusion 11 can rotate relative to the magnetic body in the second mounting groove 42.
[0072] By rotatably placing the rotating part 13 in the second opening 50a and rotatably placing the protrusion 11 in the second mounting groove 42, the fixing effect of the first housing 40 and the second housing 50 on the swing arm 10 can be improved, thereby improving the stability of the swing arm 10.
[0073] In some embodiments, the swing arm 10 is provided with a sliding part 14, and a first groove 51 is formed on the first housing 40 and / or the second housing 50, and the sliding part 14 is slidably disposed in the first groove 51.
[0074] By providing a sliding part 14 on the swing arm 10, a first groove 51 is formed on the first housing 40 and / or the second housing 50. The sliding part 14 is slidably disposed in the first groove 51. When the drive assembly 20 drives the swing arm 10 to rotate, the sliding part 14 can slide along the groove. On the one hand, the first groove 51 provides a clear guide path for the sliding part 14. The cooperation between the first groove 51 and the sliding part 14 can effectively limit the range of motion of the swing arm 10, so that the swing arm 10 can only move on a predetermined trajectory, avoiding excessive rotation or deviation from the track. On the other hand, by allowing the sliding part 14 to slide in the first groove 51, the stability of the movement of the swing arm 10 can be improved, reducing the risk of the swing arm 10 shaking or vibrating during rotation, and improving the cleaning effect of the cleaning equipment 1000.
[0075] This application provides a cleaning device, which includes a swing arm, a drive assembly, and a magnetic sensing assembly. The swing arm has a shaft hole and a first mounting groove communicating with the shaft hole. The drive assembly includes a drive body and a rotating shaft connected to the drive body, with one end of the rotating shaft disposed within the shaft hole. The magnetic sensing assembly is at least partially disposed within the first mounting groove. The drive body drives the swing arm to rotate via the rotating shaft, and the magnetic sensing assembly generates a magnetic field that changes with the rotation of the rotating shaft. The magnetic field of the magnetic sensing assembly changes with the rotation of the rotating shaft, and the magnetic sensing assembly can determine whether the swing arm is obstructed based on the change in the magnetic field. This allows the cleaning device to quickly overcome the obstruction and continue cleaning operations when the swing arm is obstructed, effectively improving the cleaning effect of the cleaning device.
