[0063] To illustrate the technical solutions described in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0064] Please see Figure 1 and Figure 2 As shown, this application first provides a toilet cleaning device 100, which is used to install on a toilet 90 (please refer to...). Figure 11 (As shown) on the outside side, and used to clean the surface of the toilet 90.

[0065] like Figure 1 and Figure 2 As shown, the toilet cleaning device 100 includes a base 2, a movable arm assembly 3, and at least one cleaner 4. The base 2 is fixedly mounted on the outer side of the toilet 90, and the movable arm assembly 3 is disposed on the base 2 and is used to move the cleaner 4. The cleaner 4 is used to clean the surface of the toilet 90 by contacting or not contacting the surface of the toilet 90.

[0066] Figure 1 Only the mounting surface 900 on the outer side of the toilet 90 is shown. This mounting surface 900 is a fixed surface within the space; specifically, it can be a fixed surface on the toilet 90, or a surface within the space that is stationary relative to the toilet 90. The base 2 is fixedly mounted on this mounting surface 900.

[0067] like Figure 2 and Figure 5As shown, in the embodiments of this application, the movable arm assembly 3 includes a first arm 31, a second arm 32, a third arm 33, a fourth arm 34, a fifth arm 35, and a sixth arm 36 that are rotatably connected in sequence; wherein, the first arm 31 is also rotatably mounted on the base 2. The cleaner 4 is connected to the end of the sixth arm 36 opposite to the fifth arm 35, as shown. Figure 1 and Figure 2 As shown. The end of the sixth arm 36 that is opposite to the fifth arm 35 is the end of the sixth arm 36, which is also the end of the movable arm assembly 3.

[0068] Thus, through the individual movements of the first arm 31, the second arm 32, the third arm 33, the fourth arm 34, the fifth arm 35, and the sixth arm 36, the cleaner 4 can reach different points in the space to clean the surface of the toilet 90.

[0069] The toilet cleaning device 100 provided in this application embodiment has a movable arm assembly 3 rotatably connected to the base 2. The movable arm assembly 3 includes a first arm 31, a second arm 32, a third arm 33, a fourth arm 34, a fifth arm 35, and a sixth arm 36 rotatably connected in sequence. Each adjacent arm can rotate relative to the other. The toilet cleaning device 100 has multiple degrees of freedom, which allows the cleaner 4 to flexibly reach more positions in the space, adapt to various types and models of toilets 90, avoid cleaning blind spots, and improve the cleaning effect on the surface of the toilet 90.

[0070] The cleaner 4 and the end of the sixth arm 36 can be fixedly connected or detachably connected. For example... Figure 4 As shown, the number of cleaners 4 can be one or more. In some embodiments, such as... Figure 4 As shown, there are multiple cleaners 4, and each cleaner 4 is detachably connected to the end of the sixth arm 36. The cleaners 4 are of different types; for example, they can be brush heads (including disc brushes, roller brushes, etc.), air blowers, etc. When one cleaner 4 is connected to the end of the sixth arm 36, the other cleaners 4 can be temporarily stored away.

[0071] The base 2 of the toilet cleaning device 100 is fixedly installed relative to the toilet 90 within a space. The toilet 90 has a specific orientation during installation and use. For ease of description, we define various directions of the toilet 90 within the space and provide an exemplary description of the toilet cleaning device 100 based on these multiple orientations. Please refer to [reference needed]. Figure 11As shown, we define the X direction as the width direction of the toilet seat 90, the Y direction as the depth direction of the toilet seat 90, and the Z direction as the height direction of the toilet seat 90. The width direction X of the toilet seat 90 can also be understood as the left-right direction, the depth direction Y of the toilet seat 90 can also be understood as the front-back direction, and the height direction Z of the toilet seat 90 can also be understood as the up-down direction. Here, "left," "right," "front," "back," "up," and "down" are determined based on the user's orientation when using the toilet seat 90.

[0072] When the toilet cleaning device 100 is installed on the mounting surface 900, its specific orientation is not particularly limited. The first axis L1 can be parallel to the Z direction or inclined to the Z direction. When the first axis L1 is parallel to the Z direction, the space occupied by the movable arm assembly 3 during rotation can be saved, especially the space in the width direction. For ease of explanation, this application illustrates and describes the first axis L1 as being parallel to the Z direction, as shown below. Figure 2 As shown.

[0073] like Figure 2 and Figure 5 As shown, in some embodiments of this application, the first arm 31 is rotatably mounted on the base 2 about the first axis L1; the second arm 32 is rotatably mounted on the first arm 31 about the second axis L2, with the second axis L2 perpendicular to the first axis L1; the third arm 33 is rotatably mounted on the second arm 32 about the third axis L3, with the third axis L3 parallel to the second axis L2; ​​the fourth arm 34 is rotatably mounted on the third arm 33 about the fourth axis L4, with the fourth axis L4 perpendicular to the third axis L3; the fifth arm 35 is rotatably mounted on the fourth arm 34 about the fifth axis L5, with the fifth axis L5 perpendicular to the fourth axis L4; and the sixth arm 36 is rotatably mounted on the fifth arm 35 about the sixth axis L6, with the sixth axis L6 perpendicular to the fifth axis L5.

[0074] The toilet cleaning device 100 has six degrees of freedom, which further improves the flexibility of the cleaner 4 in moving within space, thereby further enhancing the adaptability of the toilet cleaning device 100 to various parts of the toilet 90 surface.

[0075] It should be noted that the terms "parallel" and "perpendicular" mentioned above, as well as the terms used below, are not limited to strict mathematical standards, but allow for certain deviations. For example, when the angle between two lines is in the range of 0° to 10°, they can be considered within the parallel range of this application; when the angle between two lines is in the range of 80° to 100°, they can be considered within the perpendicular range of this application.

[0076] like Figure 2As shown, the first axis L1 is parallel to the Z direction. The toilet cleaning device 100 is located on one side of the width direction of the toilet 90, for example, on the right or left side of the toilet 90. The first arm 31 drives the second arm 32, the third arm 33, the fourth arm 34, the fifth arm 35, and the sixth arm 36 to rotate in the horizontal plane to reach multiple points in the horizontal plane; the second arm 32 drives the third arm 33, the fourth arm 34, the fifth arm 35, and the sixth arm 36 to move in the vertical plane to reach multiple points in the vertical plane. Furthermore, through the cooperation of the third arm 33, the fourth arm 34, the fifth arm 35, and the sixth arm 36, the cleaner 4 at the end can reach different planes in space and different positions within each plane. In this way, the toilet cleaning device 100 can be adapted to toilets 90 with complex shapes and surfaces.

[0077] The toilet cleaning device 100 has an unfolded state and a folded state. The unfolded state is not a single state, but rather includes multiple states with different relative positions between the first arm 31, second arm 32, third arm 33, fourth arm 34, fifth arm 35, and sixth arm 36. The folded state, relative to the unfolded state, refers to a state where the first arm 31, second arm 32, third arm 33, fourth arm 34, fifth arm 35, and sixth arm 36 have a smaller volume, such as... Figure 3 and Figure 6 , Figure 7 and Figure 9 As shown. In the folded state, the toilet cleaning device 100 is stored in a small volume in the area near the base 2 and the mounting surface 900.

[0078] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments of this application, the toilet cleaning device 100 further includes a storage compartment 1, which is fixedly mounted on the mounting surface 900, and the base 2 is fixedly disposed on the storage compartment 1. The storage compartment 1 is used to accommodate at least a portion of the movable arm assembly 3 in a folded state.

[0079] In addition, the storage compartment 1 is also used to accommodate each cleaner 4. When no cleaner 4 is connected to the end of the sixth arm 36, all cleaners 4 are located in the storage compartment 1. When one cleaner 4 is connected to the end of the sixth arm 36, the other cleaners 4 are located in the storage compartment 1. The movable arm assembly 3 can release one cleaner 4 into the storage compartment 1 by changing its extended state, and connect another cleaner 4 from the storage compartment 1.

[0080] Optionally, such as Figure 1 As shown, at least a portion of the base 2 can be located within the storage compartment 1. Further optionally, the base 2 is located below the movable arm assembly 3, with at least a portion of the base 2 located within the storage compartment 1. Figure 3As shown, on the upper side of the base 2, in the folded state, at least a portion of the movable arm assembly 3 can be located inside the storage compartment 1. In the Z direction, the upper end of the movable arm assembly 3 in the folded state can protrude beyond the upper end of the storage compartment 1, or it can be flush with or lower than the upper end of the storage compartment 1, so as to be completely located inside the storage compartment 1.

[0081] like Figure 3 , Figure 10 and Figure 11 As shown, in some embodiments of this application, in the folded state, the base 2 and the movable arm assembly 3 are completely located inside the storage compartment 1. In some optional embodiments, the storage compartment 1 includes a compartment body and a cover (not shown) that is openable and closable at the upper end of the compartment body.

[0082] The opening of the storage compartment 1, or its main body, is located on the upper side of the storage compartment 1. The movable arm assembly 3 retracts downwards into the storage compartment 1 and unfolds upwards to perform cleaning work.

[0083] The storage compartment 1, or rather the main body of the storage compartment 1, is not limited to a closed form. The shape of the storage compartment 1 only corresponds to the minimum volume of the movable arm assembly 3, and it is sufficient to roughly accommodate the movable arm assembly 3 in the folded state.

[0084] It should be noted that the "extension direction" of an arm mentioned below refers to the direction from one end of the arm to the other, and also the direction from the axis of rotation at one end to the axis of rotation at the other. For example, the extension direction of the first arm 31 refers to the direction from the first axis L1 to the second axis L2, and is also the arrangement direction of the first axis L1 and the second axis L2. The extension direction of the second arm 32 refers to the direction from the second axis L2 to the third axis L3, and is also the arrangement direction of the second axis L2 and the third axis L3. And so on.

[0085] like Figure 5 As shown, in some embodiments of this application, the base 2 includes a base body 21 and a first drive assembly 22 disposed on the base body 21. The first drive assembly 22 has an output end that rotates about a first axis L1, and a first arm 31 is connected to the output end of the first drive assembly 22.

[0086] The first arm 31 includes a first bracket 311 and a second drive assembly 312 disposed on the first bracket 311. The first bracket 311 is connected to the output end of the first drive assembly 22. The second drive assembly 312 has an output end that rotates about the second axis L2. The second arm 32 is connected to the output end of the second drive assembly 312.

[0087] The second arm 32 includes a second bracket 321 and a third drive assembly 322 disposed on the second bracket 321. The second bracket 321 is connected to the output end of the second drive assembly 312. The third drive assembly 322 has an output end that rotates about a third axis L3. The third arm 33 is connected to the output end of the third drive assembly 322.

[0088] The third arm 33 includes a third bracket 331 and a fourth drive assembly 332 disposed on the third bracket 331. The third bracket 331 is connected to the output end of the third drive assembly 322. The fourth drive assembly 332 has an output end that rotates about a fourth axis L4. The fourth arm 34 is connected to the output end of the fourth drive assembly 332.

[0089] The fourth arm 34 includes a fourth bracket 341 and a fifth drive assembly 342 disposed on the fourth bracket 341. The fourth bracket 341 is connected to the output end of the fourth drive assembly 342. The fifth drive assembly 342 has an output end that rotates about a fifth axis L5. The fifth arm 35 is connected to the output end of the fifth drive assembly 342.

[0090] The fifth arm 35 includes a fifth bracket 351 and a sixth drive assembly 352 disposed on the fifth bracket 351. The fifth bracket 351 is connected to the output end of the fifth drive assembly 342. The sixth drive assembly 352 has an output end that rotates about a sixth axis L6. The sixth arm 36 is connected to the output end of the sixth drive assembly 352.

[0091] In some embodiments, the switching positions of any one of the first drive component 22, the second drive component 312, the third drive component 322, the fourth drive component 332, and the fifth drive component 342 described above are also possible. For example, the first drive component 22 is disposed on the first bracket 311 of the first arm 31, and its output end is connected to the base body 21 of the base 2; the second drive component 312 is disposed on the second bracket 321 of the second arm 32, and its output end is connected to the first bracket 311; as... Figure 5 As shown, the third drive assembly 322 is mounted on the third bracket 331 of the third arm 33, and its output is connected to the second bracket 321; the fourth drive assembly 332 is mounted on the fourth bracket 341 of the fourth arm 34, and its output is connected to the third bracket 331; the fifth drive assembly 342 is mounted on the fifth bracket 351 of the fifth arm 35, and its output is connected to the fourth bracket 341; and the sixth drive assembly 352 is mounted on the sixth bracket 361 of the sixth arm 36, and its output is connected to the fifth bracket 351.

[0092] In some embodiments of this application, such as Figure 2 and Figure 5 As shown, the sixth arm 36 is used to drive the cleaner 4 to rotate about the seventh axis L7. This arrangement aims to improve cleaning efficiency by having the cleaner 4 clean the surface of the toilet seat 90 in a rotating manner. In some alternative embodiments, the seventh axis L7 is perpendicular to the sixth axis L6.

[0093] Specifically, such as Figure 5 As shown, the sixth arm 36 includes a sixth bracket 361 and a seventh drive assembly 362 disposed on the sixth bracket 361. The sixth bracket 361 is connected to the output end of the sixth drive assembly 362. The seventh drive assembly 362 has an output end that rotates about the seventh axis L7. The cleaner 4 can be connected to the output end of the seventh drive assembly 362. Of course, depending on the specific type of cleaner 4, the seventh drive assembly 362 can be selectively rotatably connected to the cleaner 4 or not connected. For example, for a cleaner 4 that is a blower, the sixth arm 36 is connected to the blower along the seventh axis L7, but the seventh drive assembly 362 does not need to drive the blower to rotate.

[0094] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments of this application, the fourth axis L4 is parallel to the extending direction of the fourth arm 34. In conjunction with the above, the fifth axis L5 is also perpendicular to the fourth axis L4; therefore, the fifth arm 35 can rotate about the fifth axis L5 toward the third arm 33. That is, the end of the fifth arm 35 that connects to the sixth arm 36, and the sixth arm 36, etc., can all rotate toward the third arm 33 to be as close as possible to the surface of the fourth arm 34. Thus, at least the fifth arm 35 and the fourth arm 34 are folded together.

[0095] like Figure 2 and Figure 5 As shown, in some embodiments of this application, the thickness of the fourth arm 34 along the fifth axis L5 is less than the width of the fourth arm 34 in the direction perpendicular to the fourth axis L4 and the fifth axis L5. This arrangement aims to ensure that, when the fifth arm 35 is folded onto the surface of the fourth arm 34, both the fourth arm 34 and the fifth arm 35 have a relatively small overall thickness along the fifth axis L5.

[0096] like Figure 7 and Figure 9 As shown, in the folded state, the end of the fifth arm 35 that connects to the sixth arm 36 faces the third arm 33. At this time, the extension direction of the fifth arm 35 is parallel to the extension direction of the third arm 33, that is, the extension direction of the fifth arm 35 is perpendicular to the third axis L3 and the sixth axis L6.

[0097] like Figure 7As shown, since the seventh axis L7 is perpendicular to the sixth axis L6, in the folded state, the extension direction of the sixth arm 36 is perpendicular to both the sixth axis L6 and the third axis L3, that is, the extension direction of the sixth arm 36 is parallel to the fourth axis L4. The sixth arm 36 and the fifth arm 35 are folded together with the fourth arm 34. Thus, the sixth arm 36 extends along the seventh axis L7 as a whole. This also makes the movable arm assembly 3 have a small folded volume.

[0098] Furthermore, such as Figure 7 As shown, since the sixth axis L6 is perpendicular to the fifth axis L5, it is also perpendicular to the fourth axis L4. In the folded state, as... Figure 7 As shown, in the direction parallel to the fifth axis L5, the sixth arm 36 is located on one side of the third arm 33 and the fourth arm 34. Specifically, in the direction parallel to the fifth axis L5, the fifth arm 35 and the sixth arm 36 are both located on one side of the third arm 33 and the fourth arm 34. That is, the fifth arm 35 and the sixth arm 36 are folded in the same direction to be side by side with the fourth arm 34 and the third arm 33.

[0099] like Figure 5 and Figure 7 As shown, in some embodiments of this application, the third arm 33 includes a first portion 3311, which is connected to the fourth arm 34. The thickness of the first portion 3311 along the third axis L3 is less than the width of the first portion 3311 in the direction perpendicular to the third axis L3 and the fourth axis L4.

[0100] like Figure 6 and Figure 7 As shown, in the folded state, the thickness direction of the first part 3311 is consistent with the thickness direction of the fourth arm 34, the sixth arm 36 is positioned toward the third arm 33, and the projection of the sixth arm 36 in the direction of the fifth axis L5 at least partially falls within the first part 3311.

[0101] The purpose of this arrangement is that the fourth arm 34 is connected to the first part 3311 of the third arm 33 and both have a small thickness. When the fifth arm 35 and the sixth arm 36 rotate in the direction and fold together with the fourth arm 34 and the third arm 33, the third arm 33, the fourth arm 34, the fifth arm 35 and the sixth arm 36 as a whole have a small thickness in the direction along the third axis L3.

[0102] like Figure 3 , Figure 6 and Figure 7 As shown, in some embodiments of this application, the fourth axis L4 is parallel to the extension direction of the third arm 33, the thickness of the first portion 3311 is equal to the thickness of the fourth arm 34, and the width of the first portion 3311 is equal to the width of the fourth arm 34.

[0103] The purpose of this arrangement is that the fourth arm 34 and the first part 3311 of the third arm 33 are of equal width and thickness, and in the folded state, the fourth arm 34 and the third arm 33 are completely aligned in the thickness direction and the width direction.

[0104] In some embodiments of this application, such as Figure 3 As shown, in the folded state, the fifth axis L5 is parallel to the second axis L2 and the third axis L3. This arrangement aims to ensure that the second arm 32, the third arm 33, the fourth arm 34, and the fifth arm 35 are all parallel, allowing them to fold together and approach each other in the same direction. Specifically, folding occurs in a direction perpendicular to the second axis L2, the third axis L3, and the fifth axis L5. In other words, the third arm 33, the fourth arm 34, and the fifth arm 35 can all fold downwards and approach the second arm 32.

[0105] like Figure 7 As shown, in some embodiments of this application, the fifth axis L5 is very close to the second axis L2. In some embodiments, the fourth axis L4 may be parallel to the extension direction of the second arm 32, or in other words, the fourth axis L4 is parallel to the perpendicular line connecting the second axis L2 and the third axis L3. Similarly, as mentioned above, "parallel" here refers to a very small angle, for example, within 10°. The purpose of this arrangement is to minimize the space between the third arm 33, the fourth arm 34, and the second arm 32.

[0106] like Figure 3 , Figure 7 As shown, the fifth axis L5 is parallel to the third axis L3 and the second axis L2, which also makes the fifth arm 35 located on the side of the fourth arm 34 along the fifth axis L5.

[0107] like Figure 3 As shown, on the vertical line connecting the second axis L2 and the third axis L3, there is a gap between the side of the fourth arm 34 facing away from the fourth axis L4 and the second drive assembly 312. In other words, on the vertical line connecting the second axis L2 and the third axis L3, the total length of the third arm 33 and the fourth arm 34 is less than the total length of the second arm 32. This arrangement aims to allow the third arm 33, the fourth arm 34, and the fifth arm 35 to fully enter the space between the second axis L2 and the third axis L3, so as to be as parallel as possible to the second arm 32. The first bent arm 3212 and the second bent arm 3213 can be chosen individually or simultaneously. Figure 5 As shown, in some embodiments of this application, the two ends of the second support body 3211 are respectively connected to the first bent arm 3212 and the second bent arm 3213.

[0108] Optionally, such as Figure 7 , Figure 8 and Figure 9 As shown, the first bending arm 3212 and the second bending arm 3213 are disposed on one side of the second support body 3211 along its width direction. That is, in a direction parallel to the second axis L2, the first bending arm 3212 and the second bending arm 3213 are offset from the center of the second support body 3211. In the folded state, as... Figure 7 , Figure 8 and Figure 9 As shown, the first bent arm 3212 and the second bent arm 3213 are disposed on the side of the second support body 3211 facing away from the fifth arm 35 along its width direction, that is, on the side close to the third arm 33 and the fourth arm 34. The purpose of this arrangement is to facilitate the connection between the second support 321, the third drive assembly 322 and the third arm 33, and in particular, to adapt to the positional relationship between the output ends of the second support 321 and the third drive assembly 322, and, in the Z direction, to make the second support body 3211 as aligned as possible with and covering the third arm 33, the fourth arm 34, the fifth arm 35 and the sixth arm 36.

[0109] like Figure 5 and Figure 7 As shown, in some embodiments of this application, the third arm 33 further includes a second portion 3312, which connects to the end of the first portion 3311 opposite to the fourth arm 34; the thickness of the second portion 3312 is greater than the thickness of the first portion 3311. Therefore, in a direction parallel to the third axis L3, the first portion 3311 is recessed relative to the second portion 3312 along its thickness direction to form a first clearance space 3315.

[0110] In the folded state, at least a portion of the sixth arm 36 is located within the first clearance space 3315, so that the sixth arm 36 can be as close as possible to the surface of the third arm 33 in the thickness direction.

[0111] like Figure 5 As shown, in some embodiments of this application, at least a portion of the third drive assembly 322 is located within the second portion 3312 of the third arm 33, and the output end of the third drive assembly 322 is connected to the second bracket 321.

[0112] The purpose of this arrangement is that the second part 3312 is thicker and is farther away from the sixth arm 36 in the direction parallel to the fourth axis L4. Therefore, the second part 3312 does not affect the storage of the sixth arm 36, and the larger space inside the second part 3312 is used to set up the third drive assembly 322.

[0113] That is, such as Figure 5As shown, in some embodiments of this application, a portion of the third drive assembly 322 is disposed within the second portion 3312, and the output end of the third drive assembly 322 is connected to the end of the second arm 32 facing away from the base 2. Thus, the second drive assembly 312 does not need to occupy space inside the second arm 32, and the second arm 32 can remain largely flat, facilitating the folding of the fifth arm 35 and the sixth arm 36 onto one side of the third arm 33.

[0114] In some embodiments of this application, such as Figure 5 , Figure 7 and Figure 9 As shown, at one end of the second portion 3312 near the first portion 3311, a second clearance space 3316 is provided on one side of the first portion 3311 in the width direction. In the folded state, at least a portion of the end of the sixth arm 36 away from the fifth arm 35 is located in the second clearance space 3316. Figure 7 As shown, when the toilet cleaning device 100 is switched from the unfolded state to the folded state, the fifth arm 35 rotates around the fifth axis L5, which drives the sixth arm 36 to rotate around the fifth axis L5, so that the sixth arm 36 can enter the second clearance space 3316 from the width direction of the first part 3311 and fold to be parallel to the first part 3311.

[0115] like Figure 5 , Figure 7 and Figure 9 As shown, in a direction parallel to the fourth axis L4, the second clearance space 3316 communicates with the first clearance space 3315 and is adapted to the shape of the end of the sixth arm 36 (e.g., the output end of the seventh drive assembly 362, specifically the output shaft). The end of the sixth arm 36 is used to connect the cleaner 4 and is relatively small. Therefore, forming the second clearance space 3316 on the second part 3312 can both accommodate the end of the sixth arm 36 and ensure that the second part 3312 still has sufficient internal space.

[0116] like Figure 4 As shown, in some embodiments of this application, the storage compartment 1 is provided with a storage section 11, and the storage section 11 has multiple storage slots (not shown). Different cleaners 4 can be stored in the corresponding storage slots. Since the types of cleaners 4 are different, their connection adaptation methods with the output terminal of the seventh drive component 362 may be different. In some cases, such as... Figure 4 In this case, the installation height of different cleaners 4 in the storage compartment 1 may vary.

[0117] In some embodiments of this application, such as Figure 5 , Figure 7 and Figure 9As shown, in a direction perpendicular to the third axis L3 and the fourth axis L4, a third clearance space 3317 is provided on one side of the third arm 33 and at the end near the third axis L3. The third clearance space 3317 is used to avoid at least one cleaner 4 on the storage part 11 of the storage compartment 1. Alternatively, in a direction perpendicular to the third axis L3 and the fourth axis L4, the third clearance space 3317 is provided on one side of the second part 3312. Or, the width of the second part 3312 is smaller than the width of the first part 3311, thereby forming the third clearance space 3317 on one side of the width direction of the second part 3312. Thus, when the movable arm assembly 3 is folded and stored in the storage compartment 1, the third clearance space 3317 can be adapted to one or more cleaners 4 at a higher position, such that at least a portion of at least one cleaner 4 is located within the third clearance space 3317. Meanwhile, since the second part 3312 still has a large thickness in the direction parallel to the third axis L3, the second part 3312 still has sufficient internal space.

[0118] like Figure 3 , Figure 6 and Figure 7 As shown, in the folded state, the extension direction of the third arm 33 is the same as that of the second arm 32, and the end of the third arm 33 used to connect with the fourth arm 34 is positioned towards the first arm 31. That is, in the folded state, the third arm 33 can be rotated in the opposite direction to get as close as possible to the surface of the second arm 32, and simultaneously, the fourth arm 34 also moves closer to the surface of the second arm 32 as the third arm 33 rotates in the opposite direction. In this way, the third arm 33 and the fourth arm 34 are folded together with the second arm 32.

[0119] In some embodiments of this application, such as Figure 3 As shown, in the folded state, the fifth axis L5 is parallel to the second axis L2 and the third axis L3. In the unfolded state, the fifth axis L5 may not be parallel to the second axis L2 and the third axis L3. Specifically, by rotating the output end of the fourth drive assembly 332, the fourth arm 34 can be rotated to a state corresponding to the first part 3311 of the third arm 33, so that the first part 3311 of the third arm 33 and the fourth arm 34 together form an integral thin plate structure.

[0120] The purpose of this arrangement is to ensure that the second axis L2, the third axis L3, and the fifth axis L5 all run in the same direction. Figure 3Taking the second axis L2, third axis L3, and fifth axis L5 shown as horizontal as an example, this allows the second arm 32, third arm 33, fourth arm 34, and fifth arm 35 to approach and fold together in the same direction. Specifically, folding occurs in a direction perpendicular to the second axis L2, third axis L3, and fifth axis L5. In other words, the third arm 33, fourth arm 34, and fifth arm 35 can all fold downwards and approach the second arm 32.

[0121] like Figure 6 and Figure 7 As shown, the third arm 33, the fourth arm 34 and the fifth arm 35 can approach the second arm 32 and fold together with the second arm 32 side by side.

[0122] Furthermore, the fifth arm 35 and the sixth arm 36 are also folded together with the second arm 32. Thus, in the movable arm assembly 3, the second arm 32, the third arm 33, the fourth arm 34, the fifth arm 35, and the sixth arm 36 are folded into a generally rectangular structure, realizing the folding of the movable arm assembly 3.

[0123] like Figure 6 and Figure 7 As shown, in some embodiments of this application, the width of the second support 321 along the second axis L2 is greater than the thickness of the second support 321, and the thickness direction of the second support 321 is perpendicular to the second axis L2 and perpendicular to the extension direction of the second arm 32. The purpose of this arrangement is that the second support 321 is generally thin-plate shaped, and when the third arm 33, fourth arm 34, fifth arm 35, and sixth arm 36 are folded to one side of the thickness direction of the second support 321, the second arm 32, third arm 33, fourth arm 34, fifth arm 35, and sixth arm 36 have a relatively small overall size.

[0124] like Figure 5 and Figure 7 As shown, in some embodiments of this application, the second support 321 includes a second support body 3211, a first bent arm 3212, and a second bent arm 3213. The extension direction of the second support body 3211 is parallel to the arrangement direction of the second axis L2 and the third axis L3. One end of the first bent arm 3212 is rotatably connected to the third arm 33, and the other end of the first bent arm 3212 is inclined and fixedly connected to the second support body 3211. One end of the second bent arm 3213 is rotatably connected to the first arm 31, and the other end of the second bent arm 3213 is inclined and fixedly connected to the second support body 3211.

[0125] It should be noted that the aforementioned "tilted connection" refers to a non-parallel connection. That is, the first bent arm 3212 and the second support body 3211 form a certain angle, and the second bent arm 3213 and the second support body 3211 form a certain angle.

[0126] Since both the first bent arm 3212 and the second bent arm 3213 are inclined towards the second support body 3211, a generally trapezoidal semi-open space is formed between the first bent arm 3212, the second support body 3211, and the second bent arm 3213. Figure 3 and Figure 5 As shown.

[0127] like Figure 3 As shown, in the folded state, at least a portion of the third arm 33 is aligned with the first bent arm 3212 and the second bent arm 3213 in the extending direction of the second support body 3211. That is, the first bent arm 3212 and the second bent arm 3213 are configured to leave space for the third arm 33 located close to the second support body 3211, so that the third arm 33 can extend in a direction parallel to the second support body 3211, thereby being as close as possible to the second support body 3211.

[0128] like Figure 3 , Figure 6 , Figure 7 and Figure 9 As shown, in the folded state, in directions perpendicular to the second axis L2, the third axis L3, and the fourth axis L4, the third arm 33, the fourth arm 34, the fifth arm 35, and the sixth arm 36 are all located on one side of the second arm 32. Along the direction of the fifth axis L5, the fifth arm 35 and the sixth arm 36 are both located on one side of the fourth arm 34 and the third arm 33.

[0129] like Figure 1 , Figure 2 , Figure 10 and Figure 11 As shown, in some embodiments of this application, the dimension of the storage compartment 1 along the width direction of the toilet 90 is smaller than its dimension along the depth direction of the toilet 90. The storage compartment 1 is generally in the shape of a cuboid along the depth direction of the toilet 90. The purpose of this arrangement is that the volume occupied by the storage compartment 1 is small on both sides of the width direction of the toilet 90, which is beneficial to the arrangement of the toilet cleaning device 100 in the space around the toilet 90.

[0130] like Figure 4As shown, since the storage compartment 1 has a large dimension in the depth direction of the toilet bowl 90, multiple cleaners 4 can be arranged in the depth direction of the toilet bowl 90. Optionally, the multiple cleaners 4 are arranged at intervals along the depth direction of the toilet bowl 90. This allows the positions of the multiple cleaners 4 to fit the rectangular shape of the storage compartment 1, and also ensures that the multiple cleaners 4 do not interfere with each other, facilitating the independent connection and disconnection of each cleaner 4 to the end of the sixth arm 36.

[0131] like Figure 3 , Figure 4 and Figure 7 As shown, in some embodiments of this application, the first arm 31 is rotatably mounted on the base 2 around a first axis L1, the first axis L1 including the extending direction of the first arm 31. In the folded state, the first arm 31 is arranged along the height direction of the toilet 90, and the second arm 32, third arm 33, fourth arm 34, fifth arm 35 and sixth arm 36 are all arranged along the depth direction of the toilet 90. After the first arm 31, second arm 32, third arm 33, fourth arm 34, fifth arm 35 and sixth arm 36 are folded in this orientation, a relatively regular cuboid can be formed, which fits the rectangular space in the storage compartment 1.

[0132] In this embodiment, the first axis L1 includes the extending direction of the first arm 31, that is, the first arm 31 extends along the first axis L1. Figure 5 and Figure 6 As shown, the first axis L1 passes through the second axis L2 and is perpendicular to the second axis L2.

[0133] Please combine participation Figure 1 , Figure 2 as well as Figure 10 and Figure 11 As shown, in some optional embodiments of this application, in the folded state, along the depth direction of the toilet seat 90, the first arm 31 is located behind the cleaner 4, and along the height direction of the toilet seat 90, the second arm 32, third arm 33, fourth arm 34, fifth arm 35, and sixth arm 36 are all located above the cleaner 4. The purpose of this arrangement is to further adapt the relative position between the movable arm assembly 3 and the cleaner 4 to the rectangular space within the storage compartment 1, allowing the second arm 32, third arm 33, fourth arm 34, fifth arm 35, and sixth arm 36 to unfold forward as a whole and reach different positions on the surface of the toilet seat 90.

[0134] This application embodiment also provides a toilet seat system 200, such as Figure 10 As shown, it includes a toilet seat cover 92 and a toilet cleaning device 100 as described in the above embodiments. The toilet seat cover 92 includes a fixing part 921 and a flip cover 922 that are rotatably connected to each other. The fixing part 921 is used to fix it to the toilet body 91 (please refer to the reference). Figure 11The outer side of the toilet seat body 91, for example, the upper surface of the toilet seat body 91. The base 2 is fixed to the fixing part 921 and does not rotate with the rotation of the flip cover 922.

[0135] The base 2 of the toilet cleaning device 100 is used to fix to the outer side of the toilet seat 92, for example, one side surface of the fixing part 921. The mounting surface 900 can be one side surface of the fixing part 921.

[0136] This application also provides a toilet assembly 300, such as... Figure 11 As shown, it includes a toilet seat 90 and a toilet cleaning device 100 as described in the above embodiments. The base 2 is fixed to the outer side of the toilet seat 90.

[0137] Specifically, in some embodiments, the toilet 90 includes a toilet body 91 and a toilet lid 92 that is flipped onto the toilet body 91. The toilet body 91 has an internal cavity 910, and at least a portion of the toilet lid 92 is rotatably disposed on the toilet body 91 to open the cavity 910 of the toilet body 91 and close the cavity 910 of the toilet 90. Alternatively, the toilet lid 92 is closable on the toilet body 91.

[0138] The toilet seat cover 92 can be rotatably mounted on the toilet body 91 as a whole, or the toilet seat cover 92 includes a fixing part 921 and a flip cover 922 that are rotatably connected to each other. The fixing part 921 is used to fix it to the outer side surface of the toilet body 91, such as the upper surface.

[0139] The toilet cleaning device 100 is mounted on the fixing part 921 of the toilet seat 92 or on the toilet body 91. Accordingly, the mounting surface 900 can be one side surface of the fixing part 921, or, as... Figure 11 As shown, the mounting surface 900 can be one outer surface of the toilet body 91.

[0140] Please continue reading. Figure 11 As shown, in one embodiment, the toilet seat cover 92 further includes a washer 923, which is rotatably mounted on the fixing part 921 or the toilet body 91 and can rotate independently relative to the flip cover 922. Furthermore, the washer 923 is located between the toilet body 91 and the flip cover 922. It is understood that when the flip cover 922 is in the open state, the washer 923 can be in either the open or closed state; when the flip cover 922 is in the closed state, the washer 923 is in the closed state.

[0141] The base 2 of the toilet cleaning device 100 is fixed to the outer side of the toilet body 91, such as the outer left or right surface. The toilet cleaning device 100 can be fixed to one side of the toilet 90 in the width direction X. In some embodiments, to avoid obstructing the user's use of the toilet 90, the toilet cleaning device 100 can be fixed to the rear end of the toilet 90 in the depth direction Y, i.e., the end furthest from the user. In some embodiments, to prevent the toilet cleaning device 100 from interfering with the opening and closing of the toilet seat 92, the toilet cleaning device 100 can be fixed to the part of the toilet 90 with the largest or largest size (greater than a preset size) in the width direction Y.

[0142] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
