[0020] The application will be further described with reference to the drawings and specific examples. It is to be understood that the description applies to all embodiments of the application. The following examples are illustrative only and are not intended to limit the scope of the application in any way.

[0021] Referring to Figure 1 The application discloses a cleaning device 100, comprising:

[0022] a main shell 10;

[0023] a driving device 20 fixedly installed inside the main shell 10, the driving device 20 being provided with a driving connection part 21;

[0024] a rotating support 30 located outside the main shell 10, the rotating support 30 being detachably connected to the driving connection part 21, and the rotating support 30 being capable of rotating relative to the main shell 10 under the driving of the driving device 20;

[0025] a non-contact inductor 40 fixedly arranged inside the main shell 10, the non-contact inductor 40 being used for collecting an induction signal towards a side where the rotating support 30 is located;

[0026] a controller 50 electrically connected to the non-contact inductor 40 and the driving device 20, the controller 50 being used for judging whether the rotating support 30 is installed in place according to whether the induction signal of the non-contact inductor 40 to the rotating support 30 satisfies a preset threshold condition.

[0027] The application has the following beneficial effects: the non-contact inductor 40 is fixedly arranged in the interior of the main shell 10, and is used for collecting an induction signal from the side where the rotating support 30 is located, so that the non-contact inductor 40 can adapt to the stationary state and the non-stationary state of the rotating support 30 to collect signals; and the controller 50 is electrically connected with the non-contact inductor 40 and the driving device 20, and judges whether the rotating support 30 is installed in place according to whether the induction signal of the non-contact inductor 40 to the rotating support 30 meets a preset threshold condition. It can be seen that the non-contact inductor 40 is not in contact with the rotating support 30, and only needs to further judge whether the rotating support 30 is installed in place through the strength of the induction signal, that is, can judge whether the rotating support 30 falls off from the cleaning device 100 or is taken off by a user, and the like, so that the driving device 20 can be prevented from entering an idle state and unable to normally perform a cleaning work.

[0028] It can be understood that the cleaning device 100 can be a cleaning robot, for example, the cleaning device 100 can be a sweeping robot, a mopping robot, a sweeping and mopping integrated robot, a wiping robot, a washing robot or an air purification robot, etc., which is not limited herein; the cleaning device 100 can also be a handheld cleaning device 100, for example, the cleaning device 100 can be a handheld sweeper, a handheld mop, a handheld washer or a handheld wiper, etc., which is not limited herein.

[0029] In the embodiment, the rotating support 30 is a mop support, and the rotating axis direction of the rotating support 30 is substantially parallel to the height direction of the cleaning device 100, that is, the rotating axis direction of the rotating support 30 is substantially perpendicular to the surface to be cleaned. The rotating support 30 is substantially disc-shaped, and the surface of the rotating support 30 away from the bottom side of the main shell 10 can be provided with a cleaning pad, so that the driving device 20 can drive the rotating support 30 and the cleaning pad to rotate synchronously, and then the surface to be cleaned is wiped.

[0030] In other embodiments, the rotating support 30 can also be a side brush support, and the rotating axis direction of the rotating support 30 is substantially parallel to the height direction of the cleaning device 100, that is, the rotating axis direction of the rotating support 30 is substantially perpendicular to the surface to be cleaned. One or more than two groups of brush bodies can be arranged on the circumferential side of the rotating support 30, so that the driving device 20 can drive the rotating support 30 and the one or more than two groups of brush bodies to rotate synchronously, and then the dust and debris on the surface to be cleaned are swept.

[0031] In other embodiments, the rotating bracket 30 can also be a rolling brush bracket, and the rotating axis of the rotating bracket 30 is substantially perpendicular to the height direction of the cleaning device 100, that is, the rotating axis of the rotating bracket 30 is substantially parallel to the surface to be cleaned. The rotating bracket 30 is substantially columnar, and the circumferential side of the rotating bracket 30 can be provided with one or a combination of two or more cleaning media such as brush bristles, rubber strips, fluff, cloth strips, or fiber layers, so that the driving device 20 can drive the rotating bracket 30 and the one or the combination of two or more cleaning media to rotate synchronously, thereby cleaning the dust and debris on the surface to be cleaned.

[0032] In the present embodiment, the shape of the main housing 10 is not limited here, and those skilled in the art can set it according to actual needs. The main housing 10 has an inner cavity and can provide mounting space and bearing action for the driving device 20. It can be understood that the main housing 10 can be the main part of the cleaning device 100, that is, the main housing 10 can also provide mounting space for the main board, battery assembly, cable, sensing system, and driving device 20 of the cleaning device 100. Of course, in other embodiments, the main housing 10 can also be a partial housing structure of the cleaning device 100, that is, the main housing 10 can be assembled on the device main body of the cleaning device 100, and the main housing 10 can be detached from the device main body of the cleaning device 100 as a detachable module.

[0033] The driving device 20 includes a driving motor 22, at least one transmission member, and a driving connection portion 21, and the at least one transmission member is transmissionally connected between the driving motor 22 and the driving connection portion 21. The at least one transmission member can include a transmission gear set, so that the driving motor 22 can drive the driving connection portion 21 to rotate through the transmission gear set; or the at least one transmission member can include a transmission belt, so that the driving motor 22 can drive the driving connection portion 21 to rotate through the transmission belt.

[0034] In some embodiments, the driving connection portion 21 is provided with a convex shaft, and the rotating bracket 30 is provided with a concave portion that is detachably connected with the convex shaft. In other embodiments, the driving connection portion 21 is provided with a concave portion, and the rotating bracket 30 is provided with a convex shaft that is detachably connected with the concave portion.

[0035] It can be understood that the sensing signal of the non-contact sensor 40 is positively correlated with the distance between the non-contact sensor 40 and the rotating support 30, that is, the distance between the non-contact sensor 40 and the rotating support 30. When the rotating support 30 is connected to the driving connection part 21, the non-contact sensor 40 is close enough to the rotating support 30, and the non-contact sensor 40 can generate a significant sensing signal to the rotating support 30, so that the sensing signal of the non-contact sensor 40 meets the preset threshold condition, thereby being able to represent that the rotating support 30 is installed in place. The specific value of the preset threshold condition is not limited here, and those skilled in the art can adjust the specific value of the preset threshold condition according to the actual application needs.

[0036] Please refer to Figure 2 In the embodiment, the non-contact sensor 40 can include a Hall sensor, and the rotating support 30 is provided with a magnetic part. The Hall sensor can generate a sensing signal by sensing the magnetic field of the magnetic part. The controller 50 judges that the rotating support 30 is installed in place according to that the sensing signal of the non-contact sensor 40 to the rotating support 30 meets the preset threshold condition. The controller 50 judges that the rotating support 30 is not installed in place according to that the sensing signal of the non-contact sensor 40 to the rotating support 30 does not meet the preset threshold condition, and then controls the driving device 20 to stop working to avoid continuous idling of the driving device 20 and damage.

[0037] Please refer to Figure 3 In other embodiments, the non-contact sensor 40 can also include a light emitter 401 and a light receiver 402. The light emitter 401 is used to emit a detection light signal to the side where the rotating support 30 is located, and the light receiver 402 is used to receive a reflected light signal to the side where the rotating support 30 is located. The emitted light signal can be formed by the detection light signal encountering the rotating support 30 and being reflected. Similarly, the controller 50 judges that the rotating support 30 is installed in place according to that the sensing signal of the non-contact sensor 40 to the rotating support 30 meets the preset threshold condition. The controller 50 judges that the rotating support 30 is not installed in place according to that the sensing signal of the non-contact sensor 40 to the rotating support 30 does not meet the preset threshold condition, and then controls the driving device 20 to stop working to avoid continuous idling of the driving device 20 and damage.

[0038] Please refer to Figure 2Further, the rotating support 30 is provided with a non-contact sensing member 60, and the minimum interval distance between the non-contact sensing member 60 and the non-contact inductor 40 is less than or equal to a preset distance threshold during the rotation of the rotating support 30 relative to the main housing 10. The preset distance threshold is 5 mm to 16 mm. For example, the preset distance threshold can be 5 mm, 8 mm, 13 mm, or 15 mm. By setting the minimum interval distance between the non-contact sensing member 60 and the non-contact inductor 40 to be less than or equal to the preset distance threshold, the overall structure is compact, and in-situ detection can be achieved without interfering with the rotation of the rotating support 30. The non-contact sensing member 60 can be the magnetic part. In other embodiments, the non-contact sensing member 60 can also be a structure that reflects the probe light signal.

[0039] During the rotation of the rotating support 30 relative to the main housing 10, the interval distance between the non-contact sensing member 60 and the non-contact inductor 40 changes periodically, i.e., between the minimum interval distance and the maximum interval distance; or the interval distance between the non-contact sensing member 60 and the non-contact inductor 40 remains a fixed value during the rotation of the rotating support 30 relative to the main housing 10.

[0040] Please refer to Figure 2 and Figure 4 In the present embodiment, the non-contact sensing member 60 is in a block shape, and is located on one side of the rotation axis of the rotating support 30. During the rotation of the rotating support 30 relative to the main housing 10, the non-contact sensing member 60 does not continuously appear in the sensing path direction of the non-contact inductor 40.

[0041] The sensing path direction of the non-contact inductor 40 is the signal collection path direction of the non-contact inductor 40. The non-contact sensing member 60 is located on one side of the rotation axis of the rotating support 30, i.e., the non-contact sensing member 60 is spaced apart from the rotation axis of the rotating support 30, so that the non-contact sensing member 60 does not need to occupy the rotation center position of the rotating support 30, thereby facilitating the arrangement of other connection structures 32 at the center position of the rotating support 30, avoiding the case that the non-contact sensing member 60 occupies the rotation center position of the rotating support 30 while other connection structures 32 are arranged at the center position of the rotating support 30, so that the overall structure is compact, which is beneficial to reduce the height dimension of the rotating support 30.

[0042] Wherein, during the rotation of the rotating bracket 30 relative to the main housing 10, the non-contact sensing member 60 discontinuously appears in the sensing path direction of the non-contact inductor 40, i.e. the non-contact sensing member 60 can switch between the position directly opposite the non-contact inductor 40 and the position away from the non-contact inductor 40 during the rotation of the rotating bracket 30 relative to the main housing 10.

[0043] When the rotating bracket 30 is in place, during the rotation of the rotating bracket 30 relative to the main housing 10, the sensing signal of the non-contact inductor 40 to the non-contact sensing member 60 presents an up-and-down waveform, wherein when the non-contact sensing member 60 appears in the sensing path direction of the non-contact inductor 40 and directly opposite the non-contact inductor 40, the minimum interval distance between the non-contact sensing member 60 and the non-contact inductor 40 is reached, so that the sensing signal of the non-contact inductor 40 to the non-contact sensing member 60 reaches the maximum value, so that the controller 50 can determine whether the rotating bracket 30 is installed in place according to whether the maximum value of the sensing signal of the non-contact inductor 40 to the rotating bracket 30 meets the preset threshold condition. In other embodiments, the controller 50 can determine whether the rotating bracket 30 is installed in place according to whether the average value of the sensing signal of the non-contact inductor 40 to the rotating bracket 30 meets the preset threshold condition.

[0044] Wherein, when the non-contact sensing member 60 appears in the sensing path direction of the non-contact inductor 40, and the minimum interval distance between the non-contact sensing member 60 and the non-contact inductor 40 is less than or equal to the preset distance threshold, the non-contact sensing member can generate a sensing signal that meets the preset threshold condition. Wherein, the preset distance threshold is 5mm to 16mm. For example, the preset distance threshold can be 5mm, 8mm, 13mm or 15mm.

[0045] Please refer to Figure 5In other embodiments, the non-contact sensing member 60 is annular, and is arranged around the rotation axis of the rotating support 30. During rotation of the rotating support 30 relative to the main housing 10, the non-contact sensing member 60 is always arranged opposite the sensing path direction of the non-contact sensor 40. During rotation of the rotating support 30 relative to the main housing 10, the spacing distance between the non-contact sensing member 60 and the non-contact sensor 40 remains a fixed value. Thus, the non-contact sensor 40 has consistency in sensing signals of the non-contact sensing member 60 when the rotating support 30 is in a stationary state or a rotating state, and can accurately determine whether the rotating support 30 is installed in place, and the determination result has consistency.

[0046] Further, when the controller 50 determines whether the rotating support 30 is installed in place, the controller 50 first controls the driving device 20 to drive the rotating support 30 to rotate relative to the main housing 10,

[0047] If the controller 50 determines that the sensing signal of the non-contact sensor 40 to the non-contact sensing member 60 reaches a preset threshold condition, it is determined that the rotating support 30 is in place.

[0048] If the controller 50 determines that the sensing signal of the non-contact sensor 40 to the non-contact sensing member 60 does not reach the preset threshold condition, it is determined that the rotating support 30 is not in place, and the driving device 20 is controlled to stop working.

[0049] In the embodiment, the rotating speed of the rotating support 30 relative to the main housing 10 is greater than or equal to 100 RPM (Revolutions Per Minute) and less than or equal to 250 RPM (Revolutions Per Minute), for example, the rotating speed of the rotating support 30 relative to the main housing 10 can be 120 RPM to 150 RPM, or the rotating speed of the rotating support 30 relative to the main housing 10 can be 150 RPM to 200 RPM. By limiting the rotating speed of the rotating support 30 relative to the main housing 10 within the above range, the rotating speed of the rotating support 30 relative to the main housing 10 is fast and within a reasonable range (convenient for cleaning and meeting the long-term use performance of the motor), so that even if the non-contact sensing member 60 does not continuously appear in the sensing path direction of the non-contact inductor 40, the number of times the non-contact sensing member 60 appears in the sensing path direction of the non-contact inductor 40 per minute is sufficient, the sensing signal of the non-contact sensing member 60 by the non-contact inductor 40 presents an up-and-down waveform, and the distance between adjacent two wave peaks of the waveform is narrow, which is beneficial to realize that the non-contact inductor 40 generates obvious sensing signal in a short time, thereby facilitating the in-situ rapid detection of the rotating support 30.

[0050] Please refer to Figure 2 and Figure 4 Further, the horizontal spacing distance between the non-contact sensing member 60 and the rotating axis of the rotating support 30 is less than or equal to 20 mm, for example, the horizontal spacing distance between the non-contact sensing member 60 and the rotating axis of the rotating support 30 can be 13 mm, 15 mm, 16 mm or 20 mm, so that the rotation radius of the non-contact sensing member 60 around the rotating axis of the rotating support 30 is small enough, thereby making the non-contact sensing member 60 move in the annular area with small radius during the rotation of the rotating support 30 relative to the main housing 10, and the sensing signal of the non-contact sensing member 60 by the non-contact inductor 40 presents a relatively continuous up-and-down waveform, which is beneficial to realize that the non-contact inductor 40 generates obvious sensing signal in a short time, thereby facilitating the in-situ rapid detection of the rotating support 30.

[0051] In other embodiments, the horizontal spacing distance between the non-contact sensing member 60 and the rotating axis of the rotating support 30 can also be greater than 20 mm, so that the sensing signal of the non-contact sensing member 60 by the non-contact inductor 40 presents a non-continuous up-and-down waveform during the rotation of the rotating support 30 relative to the main housing 10.

[0052] Please refer toFigure 2 、 Figure 4 and Figure 6 Further, the rotating bracket 30 is provided with a rotating body 31 and a connecting structure 32 connecting the rotating body 31, the rotating body 31 is connected to the driving connecting part 21 through the connecting structure 32, and the non-contact sensing part 60 is fixedly arranged on the connecting structure 32 or the rotating body 31.

[0053] In the embodiment, the rotating bracket 30 can be one of a mop bracket, an edge brush bracket, or a roller brush bracket, which will not be described here again in detail with reference to the foregoing description. The rotating body 31 is a main part of the rotating bracket 30, which plays a role of bearing and driving the cleaning part. The connecting structure 32 is located at the rotation center of the rotating body 31. The non-contact sensing part 60 can be fixedly arranged on the connecting structure 32 or the rotating body 31 by means of gluing, hot melting, clamping, embedding, welding, or one-piece injection molding.

[0054] Please refer to Figure 2 and Figure 4 Further, the non-contact sensing part 60 is arranged obliquely on one side of the rotation axis of the rotating bracket 30, and the sensing path direction of the non-contact inductor 40 is arranged at an angle with the axis direction of the driving connecting part 21. Among them, the horizontal interval distance between the non-contact sensing part 60 and the rotation axis of the rotating bracket 30 is less than or equal to 20 mm. By arranging the non-contact sensing part 60 obliquely on one side of the rotation axis of the rotating bracket 30, the non-contact sensing part 60 is close enough to the rotation axis of the rotating bracket 30, and is arranged obliquely towards the side close to the rotation axis of the rotating bracket 30, so that the central part structure of the rotating bracket 30 is compact enough to meet the installation requirements of narrow space and the spacing requirements of the non-contact sensing part 60 and the non-contact inductor 40 (refer to the foregoing description). And because the non-contact sensing part 60 is arranged obliquely on one side of the rotation axis of the rotating bracket 30, the spacing between the non-contact sensing part 60 and the ground is increased, when the non-contact sensing part 60 is a magnetic part, the magnetic field of the non-contact sensing part 60 is not easy to attract iron filings on the ground, thereby avoiding the iron filings to continuously adhere to the bottom side of the rotating bracket 30 to interfere with its normal work.

[0055] In other embodiments, the non-contact sensing part 60 is arranged horizontally on one side of the rotation axis of the rotating bracket 30, and the sensing path direction of the non-contact inductor 40 is parallel to the axis direction of the driving connecting part 21.

[0056] Please refer toFigure 2 and Figure 4 Further, the main housing 10 is provided with a bottom surface 11 and a groove 12 recessed in the bottom surface 11, the rotating support 30 is provided with a rotating body 31 and a connecting structure 32 connected to the rotating body 31, the rotating body 31 is arranged in a spaced manner with the bottom surface 11, the connecting structure 32 is at least partially accommodated in the groove 12 and detachably connected with the driving connection part 21, the non-contact sensing part 60 is fixedly arranged on the connecting structure 32, and the non-contact sensing part 60 is at least partially accommodated in the groove 12.

[0057] Please refer to Figure 2 and Figure 4 Further, the connecting structure 32 includes a sleeve 321 and a floating support assembly 322, the sleeve 321 is fixedly connected to the central position of the rotating body 31, and the floating support assembly 322 is arranged in a floating manner inside the sleeve 321, the floating support assembly 322 is used for detachably connecting the driving connection part 21, and the non-contact sensing part 60 is embedded on the outer peripheral sidewall of the sleeve 321. Wherein, the horizontal spacing distance between the non-contact sensing part 60 and the rotation axis of the rotating support 30 is less than or equal to 20mm, for example, the horizontal spacing distance between the non-contact sensing part 60 and the rotation axis of the rotating support 30 can be 13mm, 15mm, 16mm or 20mm. By arranging the non-contact sensing part 60 in a tilted manner on one side of the rotation axis of the rotating support 30, and embedding the non-contact sensing part 60 on the outer peripheral sidewall of the sleeve 321, the non-contact sensing part 60 is close enough to the rotation axis of the rotating support 30, and is arranged in a tilted manner towards the side close to the rotation axis of the rotating support 30, so that the non-contact sensing part 60 occupies a smaller wall thickness dimension of the sleeve 321, and additional thickening of the sleeve 321 is not required, so that the central part structure of the rotating support 30 is compact enough to meet the installation requirements of a narrow space, and to meet the spacing requirements of the non-contact sensing part 60 and the non-contact inductor 40 (refer to the foregoing description).

[0058] Please refer to Figure 6 In other embodiments, the non-contact sensing part 60 is fixedly arranged on the rotating body 31. The side surface of the rotating body 31 is recessed with a recessed part, and the non-contact sensing part 60 is fixed in the recessed part, wherein the recessed part is located on the side of the rotating body 31 close to the main housing 10 or away from the main housing 10.
