Description

Technical Field

[0001] This utility model relates to the field of cleaning robots, specifically to a foldable toilet bowl autonomous cleaning robot. Background Technology

[0002] Squat toilets are widely used in homes and public health facilities due to their simple structure and hygienic use. Their cleanliness directly affects the user's experience and health. Traditional cleaning methods rely mainly on manual labor, which is inefficient and difficult to clean promptly. If user-left-behind garbage and excrement are not cleaned in time, it will affect the hygiene of the toilet floor and the squat toilet, leading to the growth of bacteria and other microorganisms. Utility Model Content

[0003] This invention provides a foldable toilet bowl self-cleaning robot, which improves upon the problem of difficulty in timely cleaning of toilet bowls in the prior art, and can clean toilet bowls in a timely manner.

[0004] To achieve the above objectives, this utility model provides a foldable toilet bowl self-cleaning robot, comprising:

[0005] The storage cavity has an opening, and a first drive rod is provided inside the storage cavity. The first drive rod is arranged parallel to the plane where the opening is located.

[0006] A flipping mechanism includes a first slider and a working plate. The first slider is slidably connected to the first driving rod along the extension direction of the first driving rod. The working plate is hinged to the first slider, and the axis of the hinge is perpendicular to the axial direction of the first driving rod. The contour of the working plate matches the opening, and the working plate includes an inner side.

[0007] A cleaning mechanism, which is slidably connected to the inner side, is used to clean the toilet bowl and / or the floor;

[0008] The flipping mechanism has a first state and a second state. In the first state, the first slider slides to one end of the first drive rod, and the working plate rotates relative to the first slider towards the storage cavity, causing the working plate and the cleaning mechanism to be stored in the storage cavity from the opening, with the inner side facing the inside of the storage cavity. In the second state, the first slider slides to the other end of the first drive rod, and the working plate rotates relative to the first slider away from the storage cavity, causing the working plate to unfold from the storage cavity, with the normal of the plane containing the inner side parallel to the axis of the first drive rod. In use, the robot is installed corresponding to the toilet bowl, so that in the first state, the working plate is located above the toilet bowl; the flipping mechanism switches to the first state, with the working plate above the toilet bowl, and the cleaning mechanism slides along the inner side to clean the toilet bowl; after cleaning, the flipping mechanism switches to the second state, and the working plate and the cleaning mechanism are stored in the storage cavity to reduce space occupation and prepare for the next cleaning. The toilet bowl is no longer obstructed by the working plate, allowing the toilet bowl to be used by the user.

[0009] As an optional technical solution, a sewage shielding mechanism is also included. The sewage shielding mechanism includes a driving component, a telescopic plate assembly, and a top plate. The driving component is connected to the receiving cavity along the normal direction of the plane containing the inner side in the first state. The top plate is connected to the driving component and is detachably connected to the side of the working plate opposite to the hinge axis of the first slider. The driving component is used to drive the top plate to move along the direction of the line connecting the working plate and the hinge side of the first slider to the opposite side. The telescopic plate assembly is connected to the top plate on both sides of the working plate opposite to the hinge axis of the first slider. The telescopic plate assembly includes multiple side plates, which are stacked along the thickness direction and slidably connected along the direction of movement of the top plate. When the flipping mechanism switches to the first state, the driving component drives the top plate to move towards the end of the working plate away from the first slider and connects it to the end of the working plate away from the first slider. The multiple side plates slide along the movement direction of the top plate, so that the working plate, the top plate, and the telescopic plate group surround the toilet bowl. At this time, when the cleaning mechanism cleans the toilet bowl, the splashing sewage will be blocked by the working plate, the top plate, and the telescopic plate group, preventing sewage from splashing to the outside and causing pollution. After the cleaning mechanism completes cleaning, the flipping mechanism switches to the second state, and the driving component drives the top plate and the telescopic plate group to retract, thereby reducing the space occupied.

[0010] As an optional technical solution, the driving assembly includes a second driving rod, a second slider, and a telescopic rod assembly. The second driving rod is arranged parallel to the first driving rod, and the second slider is slidably connected to the second driving rod. One end of the telescopic rod assembly is connected to the top plate, and the other end is connected to the second slider. The telescopic rod assembly includes multiple telescopic units connected sequentially along the moving direction of the top plate. Each telescopic unit includes two connecting rods that are hinged to each other in the middle. In the telescopic unit connected to the second slider, the end of one of the two connecting rods is hinged to the second slider, and the end of the other connecting rod is hinged to the frame. When the second slider slides in a direction that moves the ends of the two connecting rods away from each other, the telescopic unit formed by the two connecting rods is stretched axially along the second driving rod and compressed radially along the second driving rod, causing the telescopic rod assembly to shorten along the sliding direction of the top plate, thereby causing the top plate to retract towards the second slider; when the second slider slides in a direction that moves the ends of the two connecting rods closer to each other, the telescopic unit formed by the two connecting rods is compressed axially along the second driving rod and stretched radially along the second driving rod, causing the telescopic rod assembly to lengthen along the sliding direction of the top plate, thereby causing the top plate to slide away from the second slider.

[0011] As an optional technical solution, a water supply mechanism is also included. This mechanism comprises a water supply component, a nozzle mounting plate, and a first nozzle. The nozzle mounting plate is disposed opposite to the top plate. The water supply component is located on the side of the nozzle mounting plate facing away from the top plate. The first nozzle is mounted on the nozzle mounting plate and faces the top plate, and is connected to the water supply component. When the cleaning mechanism cleans the toilet bowl, the water supply mechanism can spray water through the first nozzle to soften dirt and carry away contaminant debris, thereby improving the cleaning effect of the cleaning mechanism.

[0012] As an optional technical solution, the system also includes a second nozzle and a nozzle mounting bracket. The nozzle mounting bracket is located on the side of the working plate near the top plate and installed on its inner side. The second nozzle is mounted on the nozzle mounting bracket and is positioned corresponding to the cleaning mechanism. The second nozzle is connected to the water supply assembly via a pipe. The second nozzle has a different orientation than the first nozzle, allowing it to rinse away dirt at different angles, which helps improve the cleaning effect.

[0013] As an optional technical solution, the inner side is provided with a first guide rail and a second guide rail, both of which are annular tracks, the second guide rail surrounds the first guide rail, and the first and second guide rails are provided with transmission teeth;

[0014] The cleaning mechanism is slidably mounted on the first guide rail and / or the second guide rail. The cleaning mechanism includes a moving gear that meshes with the transmission gear. Rotation of the moving gear drives the cleaning mechanism to slide on the first or second guide rail, thereby cleaning the area corresponding to the first or second guide rail. The first guide rail corresponds to the interior of the toilet bowl, and the second guide rail corresponds to the surrounding floor of the toilet bowl. Both the first and second guide rails are equipped with cleaning mechanisms, allowing simultaneous cleaning of both the interior and surrounding areas of the toilet bowl.

[0015] As an optional technical solution, the cleaning mechanism further includes a movable joint and a cleaning brush. The movable joint includes a first sub-part and a second sub-part. The first sub-part is connected to the moving gear, and the second sub-part is hinged to the first sub-part, with the hinge axis parallel to the plane of the first guide rail. The cleaning brush is connected to the second sub-part. When the flipping mechanism switches from the first state to the second state, the cleaning mechanism can be folded through the movable joint, thereby reducing the space occupied when it is stored in the storage cavity.

[0016] As an optional technical solution, the cleaning mechanism further includes a telescopic component connected to the second sub-part in a direction away from the hinge point between the first and second sub-parts. The cleaning brush is mounted on the end of the telescopic component away from the hinge point between the first and second sub-parts. The telescopic component is used to drive the cleaning brush closer to or away from the hinge point between the first and second sub-parts. The inner wall surface of the toilet bowl is curved, and the telescopic component can push the cleaning brush to conform to the surface of the toilet bowl, thereby cleaning the curved inner wall surface of the toilet bowl.

[0017] As an optional technical solution, the flipping mechanism further includes a support rod, one end of which is hinged to the frame and the other end to the working plate. The rotation plane of the support rod is parallel to the axial direction of the first drive rod. In the first state, the vertical distance between the end of the support rod hinged to the frame and the first slider along the axial direction of the first drive rod is greater than 0. In the second state, the vertical distance between the two ends of the support rod along the radial direction of the first drive rod is greater than 0. The support rod can provide a force opposite to the normal direction of the inner plane at the beginning of the switching process between the first and second states, thereby preventing the working plate from jamming during the switching process between the first and second states.

[0018] As an optional technical solution, a camera is also included. The camera is installed on the inner side and positioned corresponding to the cleaning mechanism, and its signal is connected to the cleaning mechanism. The camera can monitor the toilet bowl in real time during the cleaning process and provide feedback to the cleaning mechanism, which helps improve the cleaning effect.

[0019] One or more technical solutions provided by this utility model have at least the following technical effects or advantages:

[0020] This utility model provides a foldable toilet bowl self-cleaning robot. A first drive rod is installed within the storage cavity, along with a first slider and a working plate that are hinged together. A cleaning mechanism is located on the inner side of the working plate. The first slider is slidably connected to the first drive rod. The first drive rod, by driving the first slider, can unfold the working plate and cleaning mechanism from the storage cavity after the toilet bowl has been used to clean the toilet bowl and the floor, or retract them into the storage cavity to reduce space occupation and make the toilet bowl usable, thus achieving timely cleaning of the toilet bowl.

[0041] This utility model provides a foldable toilet bowl self-cleaning robot, comprising:

[0042] The storage cavity 1 has an opening, and a first drive rod 11 is provided inside the storage cavity 1. The first drive rod 11 is arranged parallel to the plane where the opening is located.

[0043] The flipping mechanism 2 includes a first slider 21 and a working plate 22. The first slider 21 is slidably connected to the first drive rod 11 along the extension direction of the first drive rod 11. The working plate 22 is hinged to the first slider 21, and the axis of the hinge shaft is perpendicular to the axis of the first drive rod 11. The contour of the working plate 22 matches the opening, and the working plate 22 includes an inner side 221.

[0044] Cleaning mechanism 3 is slidably connected to the inner side 221. The cleaning mechanism is used to clean the toilet bowl and / or the floor.

[0045] The flipping mechanism 2 has a first state and a second state. In the first state, the first slider 21 slides to one end of the first drive rod 11, and the working plate 22 rotates relative to the first slider 21 toward the storage cavity 1, so that the working plate 22 and the cleaning mechanism 3 are stored in the storage cavity 1 from the opening, with the inner side 221 facing the inside of the storage cavity 1. In the second state, the first slider 21 slides to the other end of the first drive rod 11, and the working plate 22 rotates relative to the first slider 21 away from the storage cavity 1, so that the working plate 22 unfolds from the storage cavity 1, with the normal of the plane containing the inner side 221 parallel to the axis of the first drive rod 11. In use, the robot is installed on the toilet bowl, so that in the first state, the working plate 22 is located above the toilet bowl; the flipping mechanism switches to the first state, with the working plate 22 located above the toilet bowl, and the cleaning mechanism 3 slides along the inner side 221 to clean the toilet bowl; after cleaning, the flipping mechanism 2 switches to the second state, and the working plate 22 and the cleaning mechanism are stored in the storage cavity 1 to reduce space occupation and prepare for the next cleaning. The toilet bowl is no longer blocked by the working plate 22, so that the toilet bowl can be used by the user.

[0046] As an optional implementation, the flipping mechanism 2 further includes a support rod 23, one end of which is hinged to the frame and the other end to the working plate 22. The plane of rotation of the support rod 23 is parallel to the axial direction of the first drive rod 11. In the first state, the vertical distance between the end of the support rod 23 hinged to the frame and the first slider 21 along the axial direction of the first drive rod 11 is greater than 0. In the second state, the vertical distance between the two ends of the support rod 23 along the radial direction of the first drive rod 11 is greater than 0. The support rod 23 can provide a force opposite to the normal direction of the plane containing the inner side 221 at the beginning of the switching process between the first and second states, thereby preventing the working plate 22 from jamming during the switching process between the first and second states.

[0047] In a preferred embodiment, the support rod 23 is L-shaped, with its short side hinged to the frame and its long side hinged to the work plate 22.

[0048] Specifically, the first drive rod 11 drives the first slider 21 to slide towards the top of the storage cavity 1, the working plate 22 is raised on the hinged side with the first slider 21, and the other side of the working plate 22 moves closer to the opening of the storage cavity 1 under the action of gravity and the constraint of the support rod 23. The cleaning mechanism 3 is closed into the storage cavity 1 by the working plate 22, thus completing the switch to the first state; the first drive rod 11 drives the first slider 21 to move towards the bottom of the storage cavity 1, the working plate 22 is lowered on the hinged side with the first slider 21, and the other side of the working plate 22 moves away from the opening of the storage cavity 1 under the constraint of the support rod 23, thus completing the switch to the second state.

[0049] The first drive rod 11 can be a lead screw driven by a motor, or a hydraulic rod, cylinder, etc. can be used as the first drive rod 11; in addition, guide rods, guide rails and other components can be provided to slide and connect with the first slider 21 to stabilize the movement trajectory of the first slider 21.

[0050] Example 2

[0051] Based on Embodiment 1, a sewage shielding mechanism 4 is also included. The sewage shielding mechanism 4 includes a drive assembly 41, a telescopic plate assembly 42, and a top plate 43. The drive assembly 41 is connected to the receiving cavity 1 along the normal direction of the plane where the inner side 221 is located in the first state. The top plate 43 is connected to the drive assembly 41 and is detachably connected to the side of the working plate 22 away from the hinge axis of the first slider 21. The drive assembly 41 is used to drive the top plate 43 to move along the direction of the line connecting the hinge side of the working plate 22 and the first slider 21 to the opposite side. The telescopic plate assembly 42 is connected to the two sides of the top plate 43 along the direction of the working plate 22 away from the hinge axis of the first slider 21. The telescopic plate assembly 42 includes multiple side plates, which are stacked along the thickness direction and slidably connected along the direction of movement of the top plate 43. When the flipping mechanism 2 switches to the first state, the drive assembly 41 drives the top plate 43 to move towards the end of the working plate 22 away from the first slider 21 and connects with the end of the working plate 22 away from the first slider 21. Multiple side plates slide along the movement direction of the top plate 43, so that the working plate 22, the top plate 43 and the telescopic plate assembly 42 surround the toilet bowl. At this time, when the cleaning mechanism 3 cleans the toilet bowl, the splashed sewage will be blocked by the working plate 22, the top plate 43 and the telescopic plate assembly 42, preventing sewage from splashing to the outside and causing pollution. After the cleaning mechanism 3 completes the cleaning, the flipping mechanism 2 switches to the second state, and the drive assembly 41 drives the top plate 43 and the telescopic plate assembly 42 to retract, thereby reducing the space occupied.

[0052] As an optional implementation, the drive assembly 41 includes a second drive rod 411, a second slider 412, and a telescopic rod assembly 413. The second drive rod 411 is arranged parallel to the first drive rod 11, and the second slider 412 is slidably connected to the second drive rod 411. One end of the telescopic rod assembly 413 is connected to the top plate 43, and the other end is connected to the second slider 412. The telescopic rod assembly 413 includes a plurality of telescopic units connected in sequence along the moving direction of the top plate 43. Each telescopic unit includes two connecting rods 4131 that are hinged to each other in the middle. In the telescopic unit connected to the second slider 412, the end of one of the two connecting rods 4131 is hinged to the second slider 412, and the end of the other connecting rod 4131 is hinged to the frame. When the second slider 412 slides in a direction that moves the ends of the two connecting rods 4131 away from each other, the telescopic unit formed by the two connecting rods 4131 is stretched axially along the second drive rod 411 and compressed radially along the second drive rod 411, causing the telescopic rod assembly 413 to shorten along the sliding direction of the top plate 43, thereby causing the top plate 43 to retract toward the second slider 412; when the second slider 412 slides in a direction that moves the ends of the two connecting rods 4131 toward each other, the telescopic unit formed by the two connecting rods 4131 is compressed axially along the second drive rod 411 and stretched radially along the second drive rod 411, causing the telescopic rod assembly 413 to extend along the sliding direction of the top plate 43, thereby causing the top plate 43 to slide away from the second slider 412.

[0053] The second drive rod 411 can be a lead screw driven by a motor, or a hydraulic rod, cylinder, etc. can be used as the second drive rod 411; in addition, guide rods, guide rails and other components can be provided to slide and connect with the second slider 412 to stabilize the movement trajectory of the second slider 412.

[0054] As an optional implementation, a water supply mechanism is also included. This mechanism includes a water supply component, a nozzle mounting plate 52, and a first nozzle 53. The nozzle mounting plate 52 is positioned opposite the top plate 43. The water supply component is located on the side of the nozzle mounting plate 52 facing away from the top plate 43. The first nozzle 53 is mounted on the nozzle mounting plate 52 and faces the top plate 43, and is connected to the water supply component. When the cleaning mechanism 3 cleans the toilet bowl, the water supply mechanism can spray water through the first nozzle 53 to soften dirt and carry away contaminant debris, thereby improving the cleaning effect of the cleaning mechanism 3.

[0055] As an optional implementation, it also includes a second nozzle 54 and a nozzle mounting bracket 55. The nozzle mounting bracket 55 is disposed on the side of the working plate 22 near the top plate 43 and installed on the inner side 221. The second nozzle 54 is mounted on the nozzle mounting bracket 55 and is disposed corresponding to the cleaning mechanism 3. The second nozzle 54 is connected to the water supply assembly through a pipe. The second nozzle 54 faces a different direction than the first nozzle 53, allowing it to rinse dirt at different angles, which helps to improve the cleaning effect.

[0056] The water supply assembly may include a water tank 51b and a water pump 51a connected to the water tank 51b, and a first nozzle 53 and a second nozzle 54 connected to the water pump 51a. When the water supply is good, the first nozzle 53 and the second nozzle 54 may be directly connected or a booster pump may be used to connect to the toilet's water supply pipeline.

[0057] As an optional implementation, the inner side 221 is provided with a first guide rail 221a and a second guide rail 221b. Both the first guide rail 221a and the second guide rail 221b are annular tracks. The second guide rail 221b surrounds the first guide rail 221a. The first guide rail 221a and the second guide rail 221b are provided with transmission teeth.

[0058] The cleaning mechanism 3 is slidably mounted on the first guide rail 221a and / or the second guide rail 221b. The cleaning mechanism 3 includes a moving gear 31, which meshes with a transmission gear. Rotation of the moving gear 31 drives the cleaning mechanism 3 to slide on the first guide rail 221a or the second guide rail 221b, thereby cleaning the area corresponding to the first guide rail 221a or the second guide rail 221b. The first guide rail 221a corresponds to the interior of the toilet bowl, and the second guide rail 221b corresponds to the ground surrounding the toilet bowl. Both the first guide rail 221a and the second guide rail 221b are equipped with the cleaning mechanism 3, allowing simultaneous cleaning of the interior and surrounding areas of the toilet bowl.

[0059] As an optional implementation, the cleaning mechanism 3 further includes a movable joint 32 and a cleaning brush 33. The movable joint 32 includes a first sub-part 321 and a second sub-part 322. The first sub-part 321 is connected to the movable gear 31, and the second sub-part 322 is hinged to the first sub-part 321, with the hinge axis parallel to the plane of the first guide rail 221a. The cleaning brush 33 is connected to the second sub-part 322. When the flipping mechanism 2 switches from a first state to a second state, the cleaning mechanism 3 can be folded through the movable joint 32, thereby reducing the space occupied when it is stored in the storage cavity 1.

[0060] It should be noted that the cleaning mechanism 3 installed on the first guide rail 221a and the cleaning mechanism 3 installed on the second guide rail 221b can use different cleaning brushes 33. The cleaning mechanism 3 installed on the first guide rail 221a needs to clean the toilet bowl with a curved inner wall and relatively limited space, so it can use a smaller cleaning brush 33 with a convex cleaning surface and an overall long strip shape to reduce cleaning dead corners and improve cleaning effect. The cleaning mechanism 3 installed on the second guide rail 221b is responsible for cleaning the flatter floor, so it can use a larger cleaning brush 33 with an overall round shape to improve cleaning efficiency.

[0061] As an optional implementation, the cleaning mechanism 3 further includes a telescopic component 34. The telescopic component 34 is connected to the second sub-part 322 in a direction away from the hinge point between the first sub-part 321 and the second sub-part 322. A cleaning brush 33 is mounted on one end of the telescopic component 34 away from the hinge point between the first sub-part 321 and the second sub-part 322. The telescopic component 34 is used to drive the cleaning brush 33 closer to or further away from the hinge point between the first sub-part 321 and the second sub-part 322. The inner wall surface of the toilet bowl is curved, and the telescopic component 34 can push the cleaning brush 33 to conform to the surface of the toilet bowl, thereby cleaning the curved inner wall surface of the toilet bowl.

[0062] The telescopic component 34 can be an electric actuator, a cylinder, or a hydraulic rod, etc., and this embodiment is not limited to these. The cleaning brush 33 can be rotatably connected to the telescopic component 34 via a motor such as a servo motor, so that it rotates during cleaning to improve the cleaning effect.

[0063] As an optional implementation, a camera 24 is also included. The camera 24 is installed on the inner side 221 and is positioned corresponding to the cleaning mechanism 3. The camera 24 is connected to the cleaning mechanism 3 via a signal. The camera 24 can monitor the toilet bowl in real time during the cleaning process of the cleaning mechanism 3 and provide feedback to the cleaning mechanism 3, which helps to improve the cleaning effect.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0065] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
