[0020] Figures 1 and 2 show a smart toilet cleaning device according to an embodiment of the present invention, which is positioned on the body of the toilet and can clean dirt on the inner wall of the toilet by inserting the nozzle 2 into the toilet and spraying a high-pressure water stream.
[0021] Referring to Figures 3 and 4, the smart toilet cleaning device according to this embodiment includes a frame 1, a nozzle 2, a first rotary drive mechanism 3, and a second rotary drive mechanism 4. Frame 1 includes positioning parts that can be positioned on at least both sides of the toilet, and a frame body that, when positioned on the body of the toilet, is at least partially above the toilet bowl portion of the toilet. Nozzle 2 is installed on the frame body of frame 1 on the side facing the toilet bowl, and when frame 1 is positioned on the toilet body and in a cleaning waiting state, nozzle 2 is at least partially located inside the toilet bowl. The cleaning waiting state refers to the state in which the smart toilet cleaning device has been installed and is ready to start operation at any time.
[0022] The first rotational drive mechanism 3 is installed on the frame body of the frame 1 and is configured to drive the nozzle 2 to rotate around the first pivot axis. The second rotational drive mechanism 4 is used to connect the first rotational drive mechanism 3 and the nozzle 2, and is configured to drive the nozzle 2 to rotate around a second pivot axis, with the first and second pivot axes not being parallel. In this embodiment, the first and second pivot axes are orthogonal. Of course, in other embodiments, the first and second pivot axes may be set at any angle, depending on the design structure of the frame 1 and other parameters, and a person skilled in the art can design other angles based on the structure of the frame 1 or other elements, assuming that the first and second pivot axes are not parallel.
[0023] By designing it in this way and installing the first rotary drive mechanism 3 and the second rotary drive mechanism 4, the nozzle 2 is given two different degrees of rotational freedom, allowing for a variety of rotation angles, which in turn allows it to cover a larger area when cleaning the toilet, resulting in a higher cleaning effect.
[0024] Specifically, referring to Figures 3 to 5, the first rotary drive mechanism 3 includes a base member 30, a first drive motor 31, and a first reduction gear train 32. Here, The base member 30 is hinged to the lower bottom surface portion of the frame 1, where the frame body faces the toilet bowl, around the first pivot axis, and the first pivot axis extends along the horizontal direction. Specifically, in this embodiment, when a person sits on the toilet, if the direction the person faces is forward, the first pivot axis is parallel to the left-right direction of the person. Of course, in other embodiments, the first pivot axis may be parallel to the front-back direction of the person, or it may be in an oblique direction that forms an angle with the horizontal direction.
[0025] The first drive motor 31 is installed on the lower bottom surface of the frame 1, where the frame body faces the toilet bowl portion of the toilet. The first drive motor 31 is connected to the base member 30 via a first reduction gear train 32. That is, the first reduction gear train 32 is installed on the load path between the base member and the first drive motor 31, thereby enabling the first drive motor 31 to drive the base member 30 at an appropriate rotational speed and rotate it around the first pivot axis.
[0026] In one embodiment, the base member 30 includes a first arm 303 and a second arm 304. Here, the first arm 303 is a short arm, and the second arm 304 is a long arm. One end of the first arm 303 is hinged to the lower bottom surface of the frame 1, where the frame body faces the toilet bowl portion of the toilet. The other end of the first arm 303 is connected to one end of the second arm 304. The angle between the first arm 303 and the second arm 304 is an obtuse angle. The other end of the second arm 304 is connected to a second rotary drive mechanism 4 and a nozzle 2.
[0027] By designing it in this way, the nozzle 2 installed at the other end of the second arm 304 can achieve a larger adjustment angle.
[0028] Referring to Figures 3, 4, and 6, in a further embodiment, the second rotary drive mechanism 4 includes a second drive motor 40 and a second reduction gear train 41. Here, The second drive motor 40 is mounted on the second arm 304 of the base member 30, and the second drive motor 40 is connected to the nozzle 2 via a second reduction gear train 41, that is, the second reduction gear train 41 is mounted on the load path between the second drive motor 40 and the nozzle 2, and the second drive motor 40 is configured to drive the nozzle 2 to rotate along the second pivot axis.
[0029] Specifically, in this embodiment, the second pivot axis extends along the vertical direction, that is, the second pivot axis and the first pivot axis are perpendicular to each other. In order to facilitate the mounting of the second rotary drive mechanism 4, the base member further includes a cylinder, which is positioned along the second pivot axis (i.e., the vertical direction), and the upper end of the cylinder is connected to the second arm 304, and the lower end of the cylinder is rotatably connected to the nozzle 2. The inside of the cylinder has an internal cavity 301, and the second drive motor 40 and the second reduction gear train 41 are installed in the internal cavity 301 of the cylinder.
[0030] A sealing partition plate 302 is further installed in the internal cavity 301 of the cylinder, and the sealing partition plate 302 divides the internal cavity 301 into an upper cavity and a lower cavity. A second drive motor 40 is installed in the upper cavity, and a second reduction gear train 41 is installed in the lower cavity and connected to the nozzle 2 to drive the nozzle 2 to rotate. The sealing partition plate 302 further has a water passage pipe, which passes from the upper cavity through the sealing partition plate 302 and the lower cavity and is sealed and rotatably connected to the nozzle 2. The upper end of the cylinder further has a through hole, and the water passage pipe passes through the through hole and extends to the upper cavity and is connected to the upper end of the water passage pipe, further forming a water passage, and water in the water tank 6 can be supplied to the nozzle 2 via the water passage pipe. In this embodiment, the second reduction gear train 41 includes a first gear and a second gear. The first gear is connected to the output shaft of the second drive motor 40, and the second gear is rotatably fitted onto the water pipe and meshes with the first gear. The end face of the second gear is connected to the nozzle 2, thereby allowing the second drive motor 40 to drive and rotate the nozzle 2.
[0031] Referring to Figures 3, 4 and 7, in a further embodiment, the smart toilet cleaning device further includes a roller brush mechanism 5, which is mounted on a frame 1 and includes a linear drive assembly 51 and at least one cylindrical roller brush 50, where at least one roller brush 50 is rotatable about its own axis and slidably mounted on the frame 1, and the linear drive assembly 51 is also mounted on the frame 1 and is configured to drive at least one roller brush 50 to reciprocate and slide along a first direction on the frame 1.
[0032] In this embodiment, the roll brush 50 is a general cylindrical roll brush 50, and the linear drive assembly 51 may be an air cylinder, a linear motor, or other drive mechanism capable of achieving linear motion, and is not specifically limited here. When a person sits on the toilet, if the direction the person faces is forward and the front-to-back direction of the person is the first direction, then the first direction, the first pivot axis, and the second pivot axis are perpendicular to each other.
[0033] Therefore, the linear drive mechanism can drive at least one roll brush 50 to move back and forth along a straight line, thereby cleaning the toilet lid or toilet seat with the roll brush 50.
[0034] Furthermore, the linear drive assembly 51 includes a third drive motor 510 and at least one linear motion component 511, the at least one linear motion component 511 being connected to at least one roll brush 50, and the third drive motor 510 is connected to at least one linear motion component 511 to drive at least one roll brush 50 by at least one linear motion component 511 to move linearly along a first direction.
[0035] Specifically, the linear motion component 511 includes a screw rod 511A and a linear slider 511B. The screw rod 511A is connected to the output terminal of a third drive motor 510 and is driven by the third drive motor 510. The linear slider 511B is screwed onto the screw rod 511A and is connected to at least one roll brush 50. When the third drive motor 510 drives the screw rod 511A to rotate, the screw rod 511A drives the linear slider 511B to move linearly along a first direction. In this embodiment, a linear guide rail extending along a first direction is installed on the frame 1, and the linear slider 511B is slidably mounted on the linear guide rail, thereby enabling the linear slider 511B to move linearly along a first direction.
[0036] In this application, when only one linear motion component 511 is installed, this linear motion component 511 may be installed on one side of the roll brush 50 and connected to one end of the roll brush 50, and the other end of the roll brush 50 may be suspended, or this linear motion component 511 may be installed in the middle of the roll brush 50, and the roll brush 50 may be connected to the linear motion component 511 via an intermediate member, thereby allowing the roll brush 50 to maintain its own rotation and simultaneously move linearly along a first direction, the intermediate member may be a bracket, the roll brush 50 may be rotatably mounted on the bracket, and the bracket may be connected to the linear motion component 511. When two linear motion components 511 are installed, the two linear motion components 511 may each be installed at both ends of the roll brush 50 and each connected to both ends of the roll brush 50. This embodiment adopts a method of installing two linear motion components 511.
[0037] In a further embodiment, there are two roller brushes 50, one above the other along the height direction, and are referred to as the upper roller brush 501 and the lower roller brush 502, that is, at least one roller brush 50 includes the upper roller brush 501 and the lower roller brush 502. Here, the lower roller brush 502 is connected to at least one linear motion component 511 and moves linearly along a first direction by the drive of the linear motion component 511, and the upper roller brush 501 is installed above the lower roller brush 502 and is configured to rotate around a third pivot axis and simultaneously around its own axis. In this embodiment, the axis of the upper roller brush 501 itself, the axis of the lower roller brush 502 itself, and the third pivot axis are installed parallel to each other, but the third pivot axis and the axis of the upper roller brush 501 itself are not coaxial.
[0038] By installing them in this manner, the space between the upper roller brush 501 and the lower roller brush 502 forms a single roller brush 50 space. When cleaning, the toilet lid or toilet seat can be held in this space of the roller brush 50, allowing for thorough cleaning of the toilet lid or toilet seat. The third pivot axis and the axis of the upper roller brush 501 itself are not coaxial, so the upper roller brush 501 rotates around the third pivot axis to adjust the size of the space of the roller brush 50, allowing it to adapt to different toilet lids or toilet seats.
[0039] In a further embodiment, the upper roll brush 501 includes at least one adapter plate 501A, one end of which is hinged to at least one linear motion component 511, and the other end of which extends along a first direction and is connected to the upper roll brush 501, thereby positioning the upper roll brush 501 obliquely above the lower roll brush 502 along the first direction. In this embodiment, a total of two adapter plates 501A are installed, and each of the two adapter plates 501A is connected to two linear motion components 511, specifically, one end of the adapter plate 501A extends downward and is hinged to a mounting seat on a linear slider 511B, and the other end extends obliquely above the lower roll brush 502 and is pivotally connected to one end of the upper roll brush 501.
[0040] With this design, the upper roller brush 501 can be pressed against the toilet lid or toilet seat by its own gravity, and unless there is interference from external forces, the upper roller brush 501 will not easily detach from the toilet lid or toilet seat during the cleaning process, effectively ensuring the cleaning effect.
[0041] The linear motion component 511 further includes a first linear motion component, a second linear motion component, a first driven wheel 511C, a second driven wheel 511D, and a transmission chain / belt 511E. Here, the first linear motion component is installed on the first end of the roll brush 50, the second linear motion component is installed on the second end of the roll brush 50, the first driven wheel 511C is connected to the first linear motion component, the second driven wheel 511D is connected to the second linear motion component, the transmission chain / belt 511E transmits power between the first driven wheel 511C and the second driven wheel 511D, and a third drive motor 510 is driven to one of the first driven wheel 511C and the second driven wheel 511D.
[0042] In this embodiment, the structures of the first linear motion component and the second linear motion component are identical and both include a screw rod 511A and a linear slider 511B. The first driven wheel 511C and the second driven wheel 511D may be sprockets or pulleys, and the transmission chain / belt 511E may be a chain or a belt. The first driven wheel 511C is connected to the screw rod 511A of the first linear motion component, and the second driven wheel 511D is connected to the screw rod 511A of the second linear motion component. The transmission chain / belt 511E transmits the first driven wheel 511C and the second driven wheel 511D, causing them to rotate synchronously. The third drive motor 510 rotates via a pair of transmission gears and the first driven wheel 511C. In this way, the third drive motor 510 drives both ends of the lower roll brush 502 to move linearly along the first direction simultaneously by the structure of the pulley or chain sprocket.
[0043] Furthermore, a pump 7 and a water tank 6 are installed on the frame 1. The water tank 6 is connected to the water inlet end of the nozzle 2 via a water pipe, and the pump 7 is used to send water from the water tank 6 to the nozzle 2 to form a high-pressure jet. Here, the water pipe can be inserted through a through hole at the top end of the cylinder and inserted into the internal cavity 301 and connected to a water passage, thereby forming a water passage on the cylinder.
[0044] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art can easily conceive of various equivalent modifications and substitutions within the technical scope disclosed herein, and all such modifications and substitutions should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be the same as the scope of protection of the claims. [Explanation of Symbols]
