Abstract

The present invention provides a cleaning device capable of switching washing and mopping functions, comprising a mop component and a rotating support arranged at the bottom of a housing of the cleaning device. The mop component comprises a water absorption surface and a hydrophobic surface, which are sleeved on the rotating support and connected to form an annular structure.

Technical Field

[0002] The present invention relates to the technical field of cleaning equipment, and in particular to a cleaning equipment with switchable washing and mopping functions and a mop switching method thereof. Background Art

[0003] The sweeping / floor scrubbing cleaning equipment is a type of smart home appliance. The body is a movable device with automated technology. It is combined with a vacuum cleaner with a dust collection box. It cooperates with the body to set the control path, walks repeatedly in the room, and automatically / manually completes the floor cleaning work in the room.

[0004] With the development of cleaning equipment, sweeping / scrubbing machines have added functions such as water storage and mopping. However, in the current existing technology, when cleaning blankets, stains on the rags can easily stain the blankets. Therefore, when cleaning blankets and other items with strong water absorption, hydrophobic rags are replaced. Although there are cleaning equipment on the market that can automatically switch the type of rag, the switching process may not be in place, or the mop may get stuck, causing the blanket to continue to be cleaned, resulting in damage to the blankets and other items, and a poor user experience.

[0005] Summary of the Invention

[0006] The main purpose of the present invention is to provide a cleaning device with switchable washing and mopping functions and a mop switching method thereof, aiming to solve the technical problem in the prior art that the rag fails to automatically switch into place, resulting in damage to items such as blankets and poor user experience.

[0007] To achieve the above objectives, the present invention provides a cleaning device with switchable washing and mopping functions, comprising:

[0008] case;

[0009] A rotating bracket, wherein the rotating bracket is arranged on the housing;

[0010] A mop assembly, the mop assembly being arranged on the rotating bracket, and the rotating bracket being used to switch the mop assembly to a carpet mopping state or other mopping state;

[0011] The first detection component is arranged above the mop component, and is used to detect that the mop component is rotated into place when the rotating bracket switches the mop component to the carpet mopping state.

[0012] Optionally, the mop assembly includes a water-absorbing surface and a hydrophobic surface, one end of the hydrophobic surface is connected to one end of the water-absorbing surface, and the other end of the hydrophobic surface is connected to the other end of the water-absorbing surface to form an annular structure, and the annular structure is sleeved on the rotating bracket;

[0013] Wherein, when the mop assembly is in the carpet mopping state, the water-absorbing surface faces upward and the hydrophobic surface faces downward; when the mop assembly is in the other mopping states, the rotating bracket drives the mop assembly to rotate at a preset speed.

[0014] Optionally, the first detection component includes:

[0015] A magnetic member, the magnetic member being arranged on the water absorbing surface;

[0016] A magnetic induction component is arranged above the mop assembly. When the mop assembly is in the carpet mopping state, the magnetic component is located directly below the magnetic induction component.

[0017] Optionally, the magnetic member is arranged at the center of the water absorbing surface.

[0018] Optionally, the magnetic induction element is a Hall element.

[0019] Optionally, the mop assembly further includes a plurality of scraping bars, which are arranged at intervals on the hydrophobic surface, and the length direction of the scraping bars is parallel to the rotation axis of the mop assembly.

[0020] Optionally, the mop switching device further includes a second detection component, which is disposed at the bottom of the shell and is used to detect a carpet. When the second detection component detects a carpet, the rotating bracket switches the mop assembly to the carpet mopping state.

[0021] Optionally, the second detection component is an ultrasonic sensor.

[0022] Optionally, the mop switching device further includes a driving member, and the rotating bracket is electrically connected to the driving member and the second detection component respectively;

[0023] The driving member is used to drive the housing to move a preset distance when the second detection component detects that the housing has left the carpet;

[0024] The rotating bracket is also used to switch the mop assembly to other mopping states after the driving member drives the shell to move a preset distance.

[0025] Wherein, in the other mopping and washing states, the hydrophobic surface of the mop assembly is basically facing upwards and the hydrophilic surface is basically facing downwards, and the rotating bracket drives the mop assembly to rotate at a preset speed.

[0026] The rotating bracket drives the mop assembly to rotate at a preset speed, including: the mop assembly rotates in a clockwise direction (ie, forward rotation) and the mop assembly rotates in a counterclockwise direction (ie, reverse rotation).

[0027] Optionally, the forward rotation and the reverse rotation are performed alternately.

[0028] Optionally, when the forward rotation and the reverse rotation are performed alternately, the hydrophobic surface is basically facing upward.

[0029] Optionally, the hydrophobic surface material includes rubber, latex, silicone or other materials that are not easily dissolved in water.

[0030] Since the hydrophobic surface material mentioned above is prone to generate noise due to friction when it comes into contact with non-carpet surfaces, such as floors, tiles, cement floors, glass, etc., the driving member drives the mop assembly to rotate forward and reverse alternately by alternating forward and reverse rotations. Within one alternating cycle, the rotation angle of the forward and reverse rotations is less than 180 degrees, thereby ensuring that the hydrophobic surface is always basically located above the hydrophilic surface, so that the hydrophobic surface has little or no contact with the non-carpet surface.

[0031] Optionally, in the non-carpet mopping state, the hydrophobic surface of the mop assembly is basically facing upward and the hydrophilic surface is basically facing downward, and the driving member controls the bracket assembly to rotate forward and reverse respectively, so that the mop assembly rotates forward and reverse respectively, and the forward / reverse angle of the mop assembly is 30 degrees, 60 degrees or 90 degrees.

[0032] The above solution greatly reduces friction noise, reduces the loss of the mop assembly, and increases the service life of the consumable part; at the same time, the back-and-forth wiping of the mop assembly also greatly improves the dirt cleaning effect.

[0033] In addition, in order to solve the above problems, the present invention also proposes a cleaning device, which is applied with the mop switching device as described above.

[0034] The cleaning equipment referred to in the above technical solution includes sweeping robots, mopping robots, floor scrubbers, etc., which can be automatic walking cleaning equipment or semi-automatic / manual walking cleaning equipment.

[0035] The technical solution of the present invention uses the rotating bracket to switch the mop assembly between different mopping modes to adapt to different cleaning situations. When cleaning highly absorbent items such as carpets, the mop assembly switches to the carpet mopping mode. After switching, the first detection component checks the mop assembly to ensure it is properly rotated, avoiding damage to carpets and other items. This improves the user experience.

[0046] The present invention proposes a mop switching device. Please refer to Figure 1. The mop switching device includes a shell 10, a rotating bracket 20, a mop assembly 30 and a first detection assembly 40. The rotating bracket 20 is arranged on the shell 10; the mop assembly 30 is arranged on the rotating bracket 20, and the rotating bracket 20 is used to switch the mop assembly 30 to a carpet mopping state or other mopping states; the first detection assembly 40 is arranged above the mop assembly 30, and the first detection assembly 40 is used to detect that the mop assembly 30 is rotated into place when the rotating bracket 20 switches the mop assembly 30 to the carpet mopping state; the other mopping states include a non-carpet mopping state.

[0047] The housing 10 is a chassis or base of the sweeping robot.

[0048] The rotating bracket 20 can be an annular bracket, which realizes the rotation function by connecting to the output shaft of the motor. Referring to Figure 2, the mop assembly 30 includes a water-absorbing surface 31 and a hydrophobic surface 32. One end of the hydrophobic surface 32 is connected to one end of the water-absorbing surface 31, and the other end of the hydrophobic surface 32 is connected to the other end of the water-absorbing surface 31 to form an annular structure. The annular structure is mounted on the rotating bracket 20.

[0049] When the rotating bracket 20 rotates, the mop assembly 30 is driven to rotate synchronously.

[0050] When the carpet needs to be cleaned, the rotating bracket 20 drives the mop assembly 30 to rotate and switch to the carpet mopping state, that is, the hydrophobic surface 32 is rotated downward to contact the carpet, and the water-absorbing surface 31 is rotated upward to avoid contact with the carpet.

[0051] When it is necessary to clean floors made of other materials such as tiles and wooden floors, the rotating bracket 20 drives the mop assembly 30 to rotate and switch to other mopping states, that is, the rotating bracket 20 drives the mop assembly 30 to rotate at a preset speed, thereby cyclically cleaning the floor.

[0052] The first detection component 40 is installed above the mop assembly 30 to detect the mop assembly 30 and determine whether the mop assembly 30 is rotated into place.

[0053] Specifically, the area of ​​the mop's hydrophobic surface 32 and the area of ​​the water-absorbing surface 31 each account for half of the entire mop assembly 30. Therefore, when switching to the carpet mopping mode, it is necessary to ensure that the entire water-absorbing surface 31 rotates to the upper half of the rotating bracket 20 to avoid contact with the carpet at the bottom. Therefore, the first detection component 40 is used to detect and ensure that the mop assembly 30 is rotated into place.

[0054] Specifically, the first detection component 40 includes a magnetic component 41 and a magnetic induction component 42. The magnetic component 41 is arranged on the water absorption surface 31; the magnetic induction component 42 is arranged above the mop component 30. When the mop component 30 is in the carpet mopping state, the magnetic component 41 is located directly below the magnetic induction component 42.

[0055] The magnetic sensing element 42 uses a Hall effect element. When the mop assembly 30 rotates, the magnetic element 41 passes under it. This Hall effect element detects changes in the magnetic field. Through debugging, the detection value when the magnetic element 41 is directly below the Hall effect element can be calculated. This detection value, or a value slightly lower than it, is used as the preset value. When the detected magnetic field strength is greater than or equal to this detection value, it indicates that the mop assembly 30 has been detected in place.

[0056] It is understandable that in order to ensure that the mop assembly 30 rotates into place, the magnetic member 41 can be set at the center of the water absorbing surface 31 to ensure that after rotation, the entire water absorbing surface 31 is located in the upper half of the rotating bracket 20.

[0057] Please refer to Figure 3 for another structural schematic diagram of the mop switching device. The main difference from Figure 1 is that the magnetic component 41 of the first detection component 40 is located on the back of the water-absorbing surface 31 of the mop component 30, that is, on the inner side of the annular mop component 30. The specific switching process is as follows: the robot vacuum cleaner stops moving, the preset rotation speed n of the rotating bracket 20 before the switching is recorded, the rotation speed of the rotating bracket 20 is gradually reduced to the switchable rotation speed m, and the rotation speed of the rotating bracket 20 is rotated at the switchable rotation speed m until the mop component rotates into place, that is, the first detection component stops rotating when it detects that the signal strength is within the preset range. This prevents the rotating bracket 20 from rotating at a high speed, which makes it difficult for the Hall element to accurately detect.

[0058] The first detection component detects that the signal strength is within a preset range, which includes: the Hall element detects that the magnetic field strength is greater than or equal to the detection value.

[0059] In order to improve compatibility, the installation positions of the magnetic component 41 and the magnetic induction component 42 can be appropriately adjusted for the shell 10 with different structures. It is only necessary to ensure that when the magnetic component 41 moves to the corresponding position of the magnetic induction component 42, the water absorption surface 31 is located in the upper half of the rotating bracket 20.

[0060] The present invention utilizes the rotating bracket 20 to switch the mop assembly 30 between different mopping modes to accommodate various cleaning situations. When cleaning highly absorbent items such as carpets, the mop assembly 30 switches to the carpet mopping mode. After this mode is switched, the first detection component 40 inspects the mop assembly 30 to ensure it is properly rotated, preventing damage to carpets and other items. This improves the user experience.

[0061] Furthermore, the mop assembly 30 further includes a plurality of scraping bars 50 , which are spaced apart and arranged on the hydrophobic surface 32 . The length direction of the scraping bars 50 is parallel to the rotation axis of the mop assembly 30 .

[0062] The scraper strip 50 may be made of rubber.

[0063] When the mop assembly 30 is in the carpet mopping state, the scraping bar 50 is moved to contact the stains on the carpet and remove the stains from the carpet; when the mop assembly 30 is in other mopping states, the rotating bracket 20 drives the mop assembly 30 to rotate continuously, so that the scraping bar 50 scrapes the garbage toward the side of the suction port of the sweeping robot, thereby improving the cleaning effect.

[0064] The movement includes the rotation of the mop assembly 30 or the walking movement of the cleaning device.

[0065] Furthermore, the mop switching device also includes a second detection component 60, which is arranged at the bottom of the shell 10. The second detection component 60 is used to detect the carpet. When the second detection component 60 detects the carpet, the rotating bracket 20 switches the mop component 30 to the carpet mopping state.

[0066] The second detection component 60 is installed at the bottom of the housing 10 to detect the cleaning surface.

[0067] The second detection component 60 may be an ultrasonic sensor, which utilizes the difference in ultrasonic reflection ability on different materials to realize the material recognition function.

[0068] In this embodiment, when the second detection component 60 does not detect a carpet, it continuously sends a high-level signal to the controller or the rotating bracket 20. Upon receiving the high-level signal, the controller or the rotating bracket 20 switches the mop assembly 30 to another mopping state, that is, the rotating bracket 20 keeps driving the mop assembly 30 at a preset speed. When the second detection component 60 detects a carpet, it sends a low-level signal to the controller or the rotating bracket 20, which switches the mop assembly 30 to the carpet mopping state.

[0069] Furthermore, the mop switching device also includes a driving member, and the rotating bracket 20 is electrically connected to the driving member and the second detection component 60 respectively; the driving member is used to drive the shell 10 to move a preset distance when the second detection component 60 detects that the carpet has left the carpet; the rotating bracket 20 is also used to switch the mop assembly 30 to other mopping states after the driving member drives the shell 10 to move a preset distance.

[0070] The driving member may include a stepper motor and an encoder, which is connected to the driving wheel of the sweeping robot, and drives the driving wheel to rotate, thereby driving the entire housing 10 to move. The encoder can record the speed of the stepper motor and thus calculate the moving distance.

[0071] It is understandable that due to installation space limitations, when the second detection component 60 leaves the carpet, the shell 10 may not completely leave the carpet. Therefore, in order to ensure the reliability of the mop switching device, the shell 10 can be driven by the driving member to continue moving a preset distance, and then switched to other mopping states through the rotating bracket 20.

[0072] Specifically, according to the different sizes of the housing 10 , different preset distances can be calculated by the encoder to control the rotation of the stepping motor.

[0073] In addition, in order to solve the above problems, the present invention also proposes a cleaning device, which is applied with the mop switching device as described above.

[0074] The housing 10 is a chassis or base of the sweeping robot.

[0075] The rotating bracket 20 can be an annular bracket, which realizes the rotation function by connecting with the output shaft of the motor.

[0076] The mop assembly 30 includes a water-absorbing surface 31 and a hydrophobic surface 32 , one end of the hydrophobic surface 32 is connected to one end of the water-absorbing surface 31 , and the other end of the hydrophobic surface 32 is connected to the other end of the water-absorbing surface 31 to form an annular structure, which is sleeved on the rotating bracket 20 .

[0077] When the rotating bracket 20 rotates, the mop assembly 30 is driven to rotate synchronously.

[0078] When the carpet needs to be cleaned, the rotating bracket 20 drives the mop assembly 30 to rotate and switch to the carpet mopping state, that is, the hydrophobic surface 32 is rotated downward to contact the carpet, and the water-absorbing surface 31 is rotated upward to avoid contact with the carpet.

[0079] When it is necessary to clean floors made of other materials such as tiles and wooden floors, the rotating bracket 20 drives the mop assembly 30 to rotate and switch to other mopping states, that is, the rotating bracket 20 drives the mop assembly 30 to rotate at a preset speed, thereby cleaning the floor in a cycle.

[0080] The first detection component 40 is installed above the mop assembly 30 to detect the mop assembly 30 and determine whether the mop assembly 30 is rotated into place.

[0081] Specifically, the area of ​​the mop's hydrophobic surface 32 and the area of ​​the water-absorbing surface 31 each account for half of the entire mop assembly 30. Therefore, when switching to the carpet mopping mode, it is necessary to ensure that the entire water-absorbing surface 31 rotates to the upper half of the rotating bracket 20 to avoid contact with the carpet at the bottom. Therefore, the first detection component 40 is used to detect and ensure that the mop assembly 30 is rotated into place.

[0082] Specifically, the first detection component 40 includes a magnetic component 41 and a magnetic induction component 42. The magnetic component 41 is arranged on the water absorption surface 31; the magnetic induction component 42 is arranged above the mop component 30. When the mop component 30 is in the carpet mopping state, the magnetic component 41 is located directly below the magnetic induction component 42.

[0083] The magnetic sensing element 42 uses a Hall effect element. When the mop assembly 30 rotates, the magnetic element 41 passes under it. This Hall effect element detects changes in the magnetic field. Through debugging, the detection value when the magnetic element 41 is directly below the Hall effect element can be calculated. This detection value, or a value slightly lower than it, is used as the preset value. When the signal strength is within the preset range, it indicates that the mop assembly 30 has been detected in place.

[0084] The first detection component detects that the signal strength is within a preset range, which includes: the Hall element detects that the magnetic field strength is greater than or equal to the detection value. It is understood that to ensure that the mop assembly 30 rotates into position, the magnetic member 41 can be positioned at the center of the water absorbing surface 31, so that after rotation, the entire water absorbing surface 31 is located in the upper half of the rotating bracket 20.

[0085] The specific switching process is as follows: the robot vacuum cleaner stops moving, records the preset rotation speed n of the rotating bracket 20 before the switching, gradually reduces the rotation speed of the rotating bracket 20 to the switchable rotation speed m, and rotates at the switchable rotation speed m until the Hall element detects that the magnetic field strength is greater than or equal to the detection value, and then stops rotating. This prevents the Hall element from being unable to accurately detect the rotating bracket 20 due to the high rotation speed of the rotating bracket 20.

[0086] In order to improve compatibility, the installation positions of the magnetic component 41 and the magnetic induction component 42 can be appropriately adjusted for the shell 10 with different structures. It is only necessary to ensure that when the magnetic component 41 moves to the corresponding position of the magnetic induction component 42, the water absorption surface 31 is located in the upper half of the rotating bracket 20.

[0087] The present invention utilizes the rotating bracket 20 to switch the mop assembly 30 between different mopping modes to accommodate various cleaning situations. When cleaning highly absorbent items such as carpets, the mop assembly 30 switches to the carpet mopping mode. After this mode is switched, the first detection component 40 inspects the mop assembly 30 to ensure it is properly rotated, preventing damage to carpets and other items. This improves the user experience.

[0088] In the other mopping and washing states, the hydrophobic surface of the mop assembly 30 is basically facing upward and the hydrophilic surface is basically facing downward, and the rotating bracket 20 drives the mop assembly 30 to rotate at a preset speed.

[0089] The rotating bracket 20 drives the mop assembly 30 to rotate at a preset speed, including: the mop assembly 30 rotating in a clockwise direction (ie, forward rotation) and the mop assembly 30 rotating in a counterclockwise direction (ie, reverse rotation).

[0090] Optionally, the forward rotation and the reverse rotation are performed alternately.

[0091] Optionally, when the forward rotation and the reverse rotation are performed alternately, the hydrophobic surface is basically facing upward.

[0092] Optionally, the hydrophobic surface material includes rubber, latex, silicone or other materials that are not easily dissolved in water.

[0093] Since the hydrophobic surface material mentioned above is prone to generate noise due to friction when it comes into contact with non-carpet surfaces, such as floors, tiles, cement floors, glass, etc., the driving member drives the mop assembly 30 to rotate forward and reverse alternately by alternating forward and reverse rotations. In addition, within one alternating cycle, the rotation angle of the forward and reverse rotations is less than 180 degrees, thereby ensuring that the hydrophobic surface is always basically located above the hydrophilic surface, so that the hydrophobic surface has little or no contact with the non-carpet surface.

[0094] Optionally, in the non-carpet mopping state, the hydrophobic surface of the mop assembly 30 is basically facing upward and the hydrophilic surface is basically facing downward. During the cleaning process of the non-carpet surface, the driving member controls the rotating bracket 20 to rotate forward and reverse respectively, so that the mop assembly 30 rotates forward and reverse respectively, wherein the forward / reverse angle of the mop assembly 30 is 30 degrees, 60 degrees or 90 degrees.

[0095] The sweeping machines / cleaning equipment referred to in the above technical solution include sweeping robots, mopping robots, floor scrubbers, etc., which can be automatic walking cleaning equipment or semi-automatic / manual walking cleaning equipment.

[0096] The above solution greatly reduces friction noise, reduces the loss of the mop assembly, and increases the service life of the consumable part; at the same time, the back-and-forth wiping of the mop assembly also greatly improves the dirt cleaning effect.

[0097] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
