[0060] Figure 1 and Figure 2 The present application provides an embodiment of a smart toilet cleaning device, which can be positioned at the barrel of the toilet and extend the spray head 2 into the toilet to spray high-pressure water flow to clean the dirt on the inner wall of the toilet.

[0061] Please refer to Figures 3 to 4 The smart toilet cleaning device provided in the embodiment comprises a rack 1, a spray head 2, a first rotary drive mechanism 3 and a second rotary drive mechanism 4. Among them,

[0062] The rack 1 at least comprises a positioning part that can be positioned on both sides of the toilet and a rack body that is at least partially located above the toilet bowl part when positioned on the barrel of the toilet;

[0063] The spray head 2 is arranged on the side of the rack body of the rack 1 facing the toilet bowl part, and when the rack 1 is positioned on the barrel of the toilet and in the cleaning state, the spray head 2 is at least partially located inside the toilet bowl part. The so-called cleaning state refers to the state that the smart toilet cleaning device is installed and can start working at any time.

[0064] The first rotary drive mechanism 3 is arranged on the rack body of the rack 1 and is configured to drive the spray head 2 to rotate around the first pivot axis;

[0065] The second rotary driving mechanism 4 is used to connect the first rotary driving mechanism 3 and the spray head 2, and is configured to drive the spray head 2 to rotate around a second pivot axis, and the first pivot axis and the second pivot axis are not parallel. In the embodiment, the first pivot axis and the second pivot axis are orthogonal. Of course, in other embodiments, the first pivot axis and the second pivot axis can be arranged at any angle, which is related to the design structure of the frame 1 and other parameters, and those skilled in the art can make other angle designs under the premise that the first pivot axis and the second pivot axis are not parallel according to the corresponding frame 1 structure or other factors.

[0066] In this way, by arranging the first rotary driving mechanism 3 and the second rotary driving mechanism 4, the spray head 2 has two different rotation degrees of freedom, the rotation angle is variable, and a larger area can be covered when cleaning the toilet, and the cleaning effect is stronger.

[0067] Specifically, please refer to Figures 3 to 5 The first rotary driving mechanism 3 includes a base member 30, a first driving motor 31, and a first speed reduction gear set 32. Among them,

[0068] The base member 30 is hinged to the lower bottom surface of the frame body of the frame 1 towards the toilet bowl part around the first pivot axis, and the first pivot axis extends in the horizontal direction. Specifically, in the embodiment, when the human body sits on the toilet, the direction facing the human body is regarded as the front, and the first pivot axis is parallel to the left-right direction of the human body. Of course, in other embodiments, the first pivot axis can also be parallel to the front-back direction of the human body, and the first pivot axis can also be an inclined direction at an angle with the horizontal direction.

[0069] The first driving motor 31 is arranged at the lower bottom surface of the frame body of the frame 1 towards the toilet bowl part, and the first driving motor 31 is connected with the base member 30 through the first speed reduction gear set 32, that is, the first speed reduction gear set 32 is arranged on the load path between the base member and the first driving motor 31, so that the first driving motor 31 can drive the base member 30 to rotate around the first pivot axis at a proper speed.

[0070] In an embodiment, the base member 30 includes a first arm 303 and a second arm 304. Among them, 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 hingedly connected to the lower bottom surface of the frame body of the frame 1 towards the toilet bowl part, the other end of the first arm 303 is connected to one end of the second arm 304, and the included angle between the first arm 303 and the second arm 304 is an obtuse angle, and the other end of the second arm 304 is connected with the second rotary driving mechanism 4 and the spray head 2.

[0071] In this way, the spray head 2 arranged at the other end of the second arm 304 can obtain a larger adjustment angle.

[0072] Please see Figure 3 , Figure 4 and Figure 6 In a further embodiment, the second rotary drive mechanism 4 includes a second drive motor 40 and a second reduction gear set 41. Wherein,

[0073] The second drive motor 40 is disposed on the second arm 304 of the base member 30, and the second drive motor 40 is connected to the nozzle 2 through the second reduction gear set 41. That is, the second reduction gear set 41 is disposed 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.

[0074] Specifically, in this embodiment, the second pivot axis extends vertically, meaning it is orthogonal to the first pivot axis. Furthermore, to facilitate the installation of the second rotary drive mechanism 4, the base structure also includes a cylinder. The cylinder is positioned along the second pivot axis (i.e., vertically), with its upper end connected to the second arm 304 and its lower end rotatably connected to the nozzle 2. The cylinder has an internal cavity 301, within which the second drive motor 40 and the second reduction gear set 41 are disposed.

[0075] A sealing partition 302 is also provided in the internal cavity 301 of the cylinder, dividing the internal cavity 301 into an upper cavity and a lower cavity. The second drive motor 40 is disposed in the upper cavity, and the second reduction gear set 41 is disposed in the lower cavity and connected to the nozzle 2 to drive the nozzle 2 to rotate. The sealing partition 302 also has a water pipe, which passes through the sealing partition 302 and the lower cavity from the upper cavity and is rotatably and sealingly connected to the nozzle 2. The upper end of the cylinder also has a through hole, through which the water pipe can pass and extend to the upper cavity to connect with the upper end of the water pipe, thereby forming a water passage. Water in the water tank 6 can be supplied to the nozzle 2 through the water pipe. In addition, in this embodiment, the second reduction gear set 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 sleeved on the water pipe and meshes with the first gear. The end face of the second gear is connected to the nozzle 2, so that the second drive motor 40 can drive the nozzle 2 to rotate.

[0076] Please see Figure 3 , Figure 4 and Figure 7 In a further embodiment, the intelligent toilet cleaning device also includes a roller brush mechanism 5, which is disposed on the frame 1 and includes a linear drive assembly 51 and at least one cylindrical roller brush 50. The at least one roller brush 50 is rotatable about its own axis and slidably disposed on the frame 1. The linear drive assembly 51 is also disposed on the frame 1 and configured to drive the at least one roller brush 50 to slide back and forth on the frame 1 along a first direction.

[0077] In this embodiment, the roller brush 50 is a common cylindrical roller brush 50, and the linear driving assembly 51 can be a pneumatic cylinder, a linear motor or other driving mechanism capable of achieving linear motion, which is not specifically limited herein. When a human body is seated on the toilet, the direction facing the human body is regarded as the front direction, and the front-rear direction of the human body is regarded as the first direction, i.e., the first direction is orthogonal to the first pivot axis and the second pivot axis.

[0078] Therefore, the linear driving mechanism can drive the at least one roller brush 50 to move back and forth along a straight line to clean the toilet cover or the toilet cushion.

[0079] Further, the linear driving assembly 51 comprises a third driving motor 510 and at least one linear motion component 511, the at least one linear motion component 511 being connected with the at least one roller brush 50, and the third driving motor 510 being connected with the at least one linear motion component 511 to drive the at least one roller brush 50 to move linearly along the first direction through the at least one linear motion component 511.

[0080] Specifically, the linear motion component 511 comprises a screw rod 511A and a linear slider 511B. The screw rod 511A is connected with the output end of the third driving motor 510 and is driven by the third driving motor 510. The linear slider 511B is threadedly connected with the screw rod 511A, and the linear slider 511B is connected with the at least one roller brush 50. When the third driving motor 510 drives the screw rod 511A to rotate, the screw rod 511A can drive the linear slider 511B to move linearly along the first direction. In this embodiment, a linear guide rail extending along the first direction is arranged on the frame 1, and the linear slider 511B is slidingly installed on the linear guide rail, so that the linear slider 511B can move linearly along the first direction.

[0081] In this application, when there is only one linear motion component 511, the linear motion component 511 can be arranged at one side of the roller brush 50 and connected with one end of the roller brush 50, and the other end of the roller brush 50 can be arranged in suspension, or the linear motion component 511 is arranged at the middle part of the roller brush 50, but the roller brush 50 is connected with the linear motion component 511 through an intermediate component, so that the roller brush 50 can move linearly along the first direction while keeping its rotation. The intermediate component can be a bracket, and the roller brush 50 is rotatably arranged on the bracket, and the bracket is connected with the linear motion component 511. When there are two linear motion components 511, the two linear motion components 511 can be arranged at the two ends of the roller brush 50 and connected with the two ends of the roller brush 50, respectively. This embodiment adopts the scheme of arranging two linear motion components 511.

[0082] In a further embodiment, two of the rolling brushes 50 are provided and arranged vertically, referred to as an upper rolling brush 501 and a lower rolling brush 502, i.e. the at least one rolling brush 50 comprises the upper rolling brush 501 and the lower rolling brush 502. The lower rolling brush 502 is connected to the at least one linear motion component 511 and driven by the at least one linear motion component 511 to move linearly in the first direction. The upper rolling brush 501 is arranged above the lower rolling brush 502 and configured to rotate around its own axis while rotating around the third pivot axis. In this embodiment, the own axis of the upper rolling brush 501, the own axis of the lower rolling brush 502 and the third pivot axis are arranged parallel to each other, but the third pivot axis is not coaxial with the own axis of the upper rolling brush 501.

[0083] In this way, a rolling brush 50 space is formed between the upper rolling brush 501 and the lower rolling brush 502, which can hold the toilet cover or the toilet cushion during cleaning to clean the toilet cover or the toilet cushion more carefully. Since the third pivot axis is not coaxial with the own axis of the upper rolling brush 501, the upper rolling brush 501 can rotate around the third pivot axis to adjust the size of the rolling brush 50 space to adapt to different toilet covers or toilet cushions.

[0084] In a further embodiment, the upper rolling brush 501 comprises at least one adapter plate 501A, one end of the adapter plate 501A is hinged to the at least one linear motion component 511, and the other end of the adapter plate 501A extends in the first direction and is connected to the upper rolling brush 501 so that the upper rolling brush 501 is located obliquely above the lower rolling brush 502 in the first direction. In this embodiment, two adapter plates 501A are provided, and the two adapter plates 501A are respectively connected to the two linear motion components 511. Specifically, one end of the adapter plate 501A extends downward and is hinged to the mounting seat on the linear sliding block 511B, and the other end extends obliquely above the lower rolling brush 502 and is rotatably connected to one end of the upper rolling brush 501.

[0085] In this way, the upper rolling brush 501 can be pressed on the toilet cover or the toilet cushion under the action of its own gravity, and the upper rolling brush 501 will not easily separate from the toilet cover or the toilet cushion during the cleaning process without external interference, effectively ensuring the cleaning effect.

[0086] The linear motion component 511 further comprises 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. The first linear motion component is arranged at the first end side of the roller brush 50, the second linear motion component is arranged at the second end side of the roller brush 50, the first driven wheel 511C is connected with the first linear motion component, the second driven wheel 511D is connected with the second linear motion component, the transmission chain / belt 511E is in transmission connection with the first driven wheel 511C and the second driven wheel 511D, and one of the first driven wheel 511C and the second driven wheel 511D is driven connected with the third driving motor 510.

[0087] In the embodiment, the first linear motion component and the second linear motion component are identical in structure and each comprises a screw rod 511A and a linear slide 511B. The first driven wheel 511C and the second driven wheel 511D can be a chain wheel or a belt wheel, and the transmission chain / belt 511E can be a chain or a belt. The first driven wheel 511C is connected with the screw rod 511A of the first linear motion component, the second driven wheel 511D is connected with the screw rod 511A of the second linear motion component, and the transmission chain / belt 511E is in transmission connection with the first driven wheel 511C and the second driven wheel 511D, so that the first driven wheel 511C and the second driven wheel 511D rotate synchronously, and the third driving motor 510 is in rotation connection with the first driven wheel 511C through a pair of transmission gears. In this way, the third driving motor 510 drives the two ends of the lower roller brush 502 to move linearly in the first direction through the structure of the belt wheel or the chain wheel.

[0088] In addition, the rack 1 is further provided with a water pump 7 and a water tank 6. The water tank 6 is connected with the water inlet end of the spray head 2 through a water pipe, and the water pump 7 is used to pump the water in the water tank 6 to the spray head 2 to form a high-pressure jet. The water pipe can pass into the internal cavity 301 from the through hole at the upper end of the cylinder and be connected with the water passing pipe, so as to form a water passing channel in the cylinder.

[0089] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
