[0047] The present invention is described below based on embodiments, but the present invention is not limited to these embodiments. In the following detailed description of the present invention, some specific details are described in detail, but well-known methods, processes, procedures, and elements are not described in detail in order to avoid obscuring the essence of the present invention.
[0048] Furthermore, those skilled in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.
[0049] Unless the context explicitly requires it, the words "comprising," "including," and similar terms throughout the specification and claims should be interpreted as encompassing rather than being exclusive or exhaustive; that is, meaning "including but not limited to."
[0050] In the description of this invention, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.
[0051] To intelligently and promptly clean the area beneath the toilet bowl, thereby reducing the workload of cleaning personnel and providing a cleaner user environment, this embodiment discloses a cleaning device for toilet bowls. Please refer to [link / reference needed]. Figure 1 , Figure 1This is a schematic diagram illustrating the installation of a cleaning device for a toilet as disclosed in this embodiment. The cleaning device 10 is fixedly installed on the toilet 20, which is fixedly installed on the wall 30. Using the cleaning device 10, the area beneath the toilet 20 is automatically cleaned after use, allowing for timely cleaning of this area. This reduces the workload of cleaning personnel and provides a cleaner environment for the restroom. In practice, the cleaning device 10 can be integrated with the toilet 20 or be a separate design, fixedly connected by connectors.
[0052] like Figure 1 As shown, the cleaning device 10 includes a cleaning mechanism 1, a stain detection sensor 3, and a controller. The cleaning mechanism 1 is fixedly installed at the bottom of the toilet bowl 20 and is used to clean a preset area at the bottom of the toilet bowl 20. The stain detection sensor 3 is used to collect feature images. It can collect a first feature image of the preset area before a person approaches the toilet bowl 20, a second feature image of the preset area when a person approaches the toilet bowl 20, and a third feature image of the preset area after the person leaves the toilet bowl 20. In specific implementation, the stain detection sensor 3 is mainly used to detect whether there are liquid stains and the degree of stains in the preset area under the toilet bowl 20. Therefore, the stain detection sensor 3 can be a camera, an infrared sensor array, or an optical rain sensor, etc., which can be selected according to the actual situation.
[0053] In this embodiment, the first feature image can be the original feature image of the preset area floor when no one is using the toilet 20. When someone approaches the toilet 20, the stain detection sensor 3 can collect a second feature image of the preset area floor. It is understood that the stain sensor 3 is not limited to collecting the second feature image at the specific moment a person approaches, but can collect it during the process of a person approaching the toilet 20. After the person leaves the toilet 20, the stain detection sensor 3 collects a third feature image of the preset area, which is the feature image of the preset area floor after use.
[0054] The stain detection sensor 3 sends the collected first feature image, second feature image, and third feature image to the controller. The controller performs a fusion algorithm on these three images and compares them with the stain condition of the preset area to determine whether the preset area needs to be cleaned. When the controller calculates that there are stains in the preset area, it outputs a cleaning command to the cleaning mechanism 1, controlling the cleaning mechanism 1 to clean the preset area; when the controller calculates that there are no stains in the preset area or that there is still a person in the current preset area, it does not clean.
[0055] In practical implementation, the cleaning device 10 can reuse the human body sensor on the toilet 20 to sense whether someone is currently using the toilet. It can acquire a first feature image when the human body sensor detects no user in front of it, and even if the controller calculates that there are stains in a preset area that need cleaning when the human body sensor detects a user, it will not clean them until the human body sensor detects no user in front of it, at which point the preset area will be cleaned. It is understood that the controller can also reuse the controller for the human body sensor.
[0056] like Figure 1 As shown, the cleaning device 10 also includes a receiving compartment 2, wherein both the cleaning mechanism 1 and the receiving compartment 2 are fixedly installed at the bottom of the toilet 20. In this embodiment, the cleaning mechanism 1 and the receiving compartment 2 can be fixedly installed at the bottom of the toilet 20 one in front of the other. Preferably, the cleaning mechanism 1 can be installed on the inside and the receiving compartment 2 on the outside, so that the receiving compartment 2 can accommodate some components of the cleaning mechanism 1.
[0057] Please refer to Figure 2 , Figure 2 This is a schematic diagram of the cleaning mechanism in a cleaning device for a toilet disclosed in this embodiment. Figure 2 As shown, the cleaning mechanism 1 includes a drive assembly 11 and a cleaning assembly 12. The drive assembly includes a first drive part 111 and a second drive part 112. One end of the second drive part 112 is fixedly connected to the first drive part 111, and the other end of the second drive part 112 is fixedly connected to the cleaning assembly 12. The first drive part 111 is used to drive the second drive part 112 and the cleaning assembly 12 to rotate in the xOy plane, and the second drive part 112 is used to drive the cleaning assembly 12 to rotate in the xOz plane.
[0058] In this embodiment, the drive assembly 11 is used to drive the cleaning assembly 12 to move. Specifically, the first drive part 111 in the drive assembly 11 can drive the cleaning assembly 12 to move horizontally on the xOy plane. During this process, the cleaning assembly 12 scrubs the ground. The second drive part 112 in the drive assembly 11 can drive the cleaning assembly 12 to move vertically on the xOz plane. During this process, the cleaning assembly 12 can rotate from the ground and be stored in the storage compartment 2 to complete the storage.
[0059] In the specific implementation process, the first drive unit 111 can be fixedly installed at the bottom of the toilet 20. It can be understood that the first drive unit 111 can be directly installed at the bottom of the toilet 20, or it can be installed at the bottom of the toilet 20 through other components.
[0060] In an optional embodiment, the cleaning mechanism 1 further includes a mounting shell 13, wherein the mounting shell 13 partially surrounds the drive assembly 11 and the cleaning assembly 12. In this embodiment, the mounting shell 13 can surround the left and right sides and the rear side of the drive assembly 11 and the cleaning assembly 12, which can not only protect the internal structure of the drive assembly 11 and the cleaning assembly 12, but also improve the overall aesthetics.
[0061] like Figure 1 As shown, the receiving compartment 2 is also fixedly installed at the bottom of the toilet 20. The cleaning component 12 can rotate on the xOz plane under the drive of the drive component 11 to be at least partially stored inside the receiving compartment 2. In this embodiment, the receiving compartment 2 can store the cleaning component 12, thereby storing the cleaning component 12 when cleaning is not required, improving the overall aesthetics, and also avoiding the external placement of the cleaning component 12 when cleaning is not required, thereby improving the cleaning effect of the cleaning component 12.
[0062] Please refer to Figure 3 , Figure 3 This is a schematic diagram of the drive assembly in a cleaning device for a toilet disclosed in this embodiment. Figure 3 As shown, the first drive unit 111 includes a first motor 1111 and a fixing frame 1112. The fixing frame 1112 is fixedly installed at the bottom of the toilet 20, and the first motor 1111 is fixedly installed on the fixing frame 1112. That is, the first motor 1111 is fixedly installed through the fixing frame 1112. Furthermore, the motor shaft of the first motor 1111 is fixedly connected to the second drive unit 112, so that when the first motor 1111 is working, it can drive the second drive unit 112 to rotate in the xOy plane, thereby realizing the function of driving the cleaning component 12 to rotate back and forth on the ground to scrub the floor.
[0063] In the specific implementation process, a positioning hole is provided on the top of the fixing frame 1112. The positioning hole on the top of the fixing frame 1112 is bolted to the positioning hole provided on the bottom of the toilet 20, so that the entire cleaning mechanism 1 is fixed to the bottom of the toilet 20 through the fixing frame 1112.
[0064] The first motor 1111 is fixedly mounted on the mounting bracket 1112. In this embodiment, the first drive unit 111 also includes a first motor mounting bracket. A positioning hole is provided below the first motor 1111, and a positioning hole is also provided above the first motor mounting bracket. The first motor 1111 is fixedly connected to the first motor mounting bracket via bolts through the positioning holes. The mounting bracket 1112 also has a positioning hole below it, and is bolted to the lower part of the first motor mounting bracket, thereby fixing the first motor 1111 on the mounting bracket 1112. Furthermore, the motor shaft of the first motor 1111 is fixedly connected to the second drive unit 112. When the first motor 1111 rotates in the xOy plane, the motor shaft of the first motor 1111 outputs power, thereby driving the second drive unit 112 to rotate in the xOy plane as well. Simultaneously, the second drive unit 112, which is fixedly connected to it, also rotates in the xOy plane.
[0065] like Figure 3 As shown, the second drive unit 112 includes a rotating base 1121, a second motor 1122, a main rocker arm 1123, and a connecting rod assembly 1124. The rotating base 1121 is fixedly connected to the first drive unit 111. Specifically, a positioning hole can be provided below the first motor 1111, and this positioning hole is bolted to the positioning hole provided above the rotating base 1121, thereby fixing the first motor 1111 to the rotating base 1121, which also achieves the fixing between the first drive unit 111 and the second drive unit 112.
[0066] The second motor 1122 is fixedly mounted on one side of the rotating base 1121. The second motor 1122 can be fixed to the rotating base 1121 by a second motor mounting bracket. Similarly, the side of the rotating base 1121 can also be provided with positioning holes that are bolted to the positioning holes on the front of the second motor mounting bracket. The positioning holes on the back of the second motor mounting bracket are bolted to the mounting holes on the front of the second motor 1122. The output end of the second motor 1122 is bolted to the positioning holes on the front of the motor shaft of the second motor 1122, so as to firmly fix the second motor 1122 to the rotating base 1121.
[0067] One end of the main joystick 1123 is rotatably connected to the rotating base 1121, and the motor shaft of the second motor 1122 is fixedly connected to the end of the main joystick 1123 connected to the rotating base 1121. In other words, when the second motor 1122 is working, it can drive the main joystick 1123 to rotate around the rotating base 1121. Specifically, the motor shaft of the second motor 1122 is bolted to the positioning hole on the main joystick 1123.
[0068] The linkage assembly 1124 is rotatably connected to the other end of the main rocker arm 1123. The linkage assembly 1124 is also rotatably connected to the cleaning assembly 12 and the rotating base 1121. The linkage assembly 1124 is rotatably connected to the other end of the main rocker arm 1123, so that when the second motor 1122 drives the main rocker arm 1123 to rotate, the main rocker arm 1123 can drive the linkage assembly 1124 to rotate, thereby driving the cleaning assembly 12 connected to the linkage assembly 1124 to rotate in the xOz plane, thereby realizing the lowering or retraction of the cleaning assembly 12.
[0069] In optional embodiments, such as Figure 3 As shown, the linkage assembly 1124 includes a first linkage 11241, a second linkage 11242, a third linkage 11243, and a gear set 11244. One end of the first linkage 11241 is rotatably connected to the other end of the main rocker arm 1123, and the other end of the first linkage 11242 is connected to the gear set 11244. In specific implementation, the connecting hole on the other end of the main rocker arm 1123 and the corresponding hole on the first linkage 11242 are positioned and rotatedly connected through the main rocker arm shaft.
[0070] One end of the second connecting rod 11242 is rotatably connected to the first gear in the gear set 11244, and the other end of the second connecting rod 11242 is rotatably connected to the rotating base 1121. In the specific implementation process, a positioning hole is provided on the upper part of the second connecting rod 11242 and is positioned and connected to the positioning hole on the right side of the rotating base 1121 through the second connecting rod shaft. The first gear in the gear set 11244 has a positioning hole and is bolted to the positioning hole below the second connecting rod 11242. The positioning hole on the first connecting rod 11241 is rotatably connected to the first gear in the gear set 11244 and the second connecting rod 11242 through the second connecting rod gear shaft.
[0071] One end of the third connecting rod 11243 is rotatably connected to the second gear in the gear set 11244, and the other end of the third connecting rod 11243 is fixedly connected to the cleaning component 12. In this embodiment, the first gear connected to the second connecting rod 11242 and the second gear connected to the third connecting rod 11243 are different gears, and the first gear and the second gear have a meshing relationship. In specific implementation, the second gear in the gear set 11244 has a positioning hole that is bolted to the positioning hole on the left side of the third connecting rod 11243, and the positioning hole on the first connecting rod 11241 is rotatably connected to the second gear in the gear set 11244 and the third connecting rod 11243 through the third connecting rod gear shaft.
[0072] In optional embodiments, such as Figure 3As shown, the second drive unit 112 also includes a buffer 1125. The end of the third link 11243 connected to the cleaning component 12 is provided with a connecting shaft. The third link 11243 has a fixing hole that is rotatably connected to the connecting shaft. The buffer 1125 is sleeved on the connecting shaft of the third link 11243. When the third link 11243 is connected to the cleaning component 12, the buffer 1125 is fixed between the fixing hole on the third link 11243 and the corresponding hole on the cleaning component 12. The buffer 1125 enables the cleaning component 12 to have an adaptive parallel function to the ground. In specific implementation, the buffer 1125 can be a snap ring.
[0073] Please see Figure 4 , Figure 4 This is an exploded view of the cleaning component in the cleaning device for a toilet disclosed in this embodiment. Figure 4 As shown, the cleaning assembly 12 includes a connecting shell 121, a cloth 122, a water spray component 123, and a water absorber 124. The connecting shell 121 is the outer casing of the cleaning assembly 12 and is connected to the second drive unit 112, specifically to the linkage assembly 1124 within the drive unit 112. The connecting shell 121 has a semi-enclosed cavity for housing the water spray component 123 and the water absorber 124. The cloth 122 is detachably attached to the water spray component 123. It can be understood that when the cloth 122 is attached to the water spray component 123, it substantially closes the opening of the connecting shell 121. In other words, the water spray component 123 and the water absorber 124, located within the cavity of the connecting shell 121, are enclosed within the connecting shell 121, completing the assembly of the cleaning assembly 12. In specific implementations, the cloth 122 can be attached to the water spray component 123 using Velcro.
[0074] The water spray component 123 is fixedly disposed within the semi-enclosed cavity of the connecting shell 121, and a positioning groove 1231 is also provided inside the water spray component 123. The water suction component 124 is at least partially fixedly disposed within the positioning groove 1231 of the water spray component 123. By fixing the water spray component 123 within the semi-enclosed cavity of the connecting shell 121 and the water suction component 124 within the cavity of the water spray component 123, the space utilization rate can be improved, thereby making the overall volume of the cleaning component 12 thinner for easier storage.
[0075] In this embodiment, the water sprayer 123 sprays water during the cleaning process to wet the rag 122, thereby improving the cleaning effect, while the water absorber 124 sucks up the water sprayed during the cleaning process to avoid leaving too much water stains on the ground after cleaning, prevent slipping, and reduce safety hazards.
[0076] In the specific implementation process, the positioning hole provided inside the connecting shell 121 is bolted to the threaded positioning hole provided on the water spraying component 123 to firmly fix the water spraying component 123 inside the connecting shell 121, while the water suction component 124 can be installed in the positioning groove 1231 of the water spraying component 123. Preferably, the positioning groove 1231 is located in the middle of the water spraying component 123.
[0077] In an optional embodiment, the cleaning assembly 12 further includes a filter screen 125, which covers the surface of the water-absorbing component 124 and is disposed together with the water-absorbing component 124 within the positioning groove 1231 of the water-spraying component 123. In this embodiment, the water-absorbing component 124 cooperates with the filter screen 125 to filter out some debris, thereby ensuring that the water-absorbing component 124 can absorb water normally and will not become clogged during long-term operation, thus extending its service life.
[0078] In an optional embodiment, the water spraying component 123 is provided with a first water spray nozzle 1232 and a second water spray nozzle 1233, which are located on both sides of the positioning groove 1231. When the cleaning component 12 sweeps to the right, the first water spray nozzle 1232 of the water spraying component 123 sprays water to supply water to the mop 122, and the middle water suction component 124 sucks away the discharged water. When the cleaning component 12 sweeps to the left, the second water spray nozzle 1233 of the water spraying component 123 sprays water to supply water to the mop 122, and the middle water suction component 124 sucks away the discharged water. This cycle is repeated to achieve simultaneous water spraying and water suction. The water spraying component 123 sprays water from the side of the nozzle facing the cleaning component 122, achieving a better cleaning effect with less water consumption. This saves water and avoids leaving too much water on the floor after cleaning, preventing slips and reducing safety hazards.
[0079] Please see Figure 5 , Figure 5 This is a schematic diagram of the structure of the receiving compartment in the cleaning device for a toilet disclosed in this embodiment. Figure 5 As shown, the receiving chamber 2 includes a chamber body 21, which is fixedly installed at the bottom of the toilet bowl 20, and two chamber doors 22 (only one chamber door 22 is shown in the figure). The two chamber doors 22 are rotatably mounted on the chamber body 21, and the two chamber doors 22 rotate in opposite directions to open or close the receiving chamber 2. In this embodiment, when cleaning is required, the two chamber doors 22 open outwards, and the cleaning component 12 stored inside the receiving chamber 2 is released. After cleaning is completed, the cleaning component 12 is re-stored into the receiving chamber 2, and the two chamber doors 22 close inwards, closing the receiving chamber. During the cleaning process, the two chamber doors 22 can remain open outwards, or they can close first after the cleaning component 12 is released, and then close again when the cleaning component 12 needs to be stored after cleaning is completed.
[0080] It is understandable that the back of the containment chamber 2 can provide a certain amount of moving space for the second drive unit 112, such as a through groove, so that the second drive unit 112 can drive the cleaning component 12 to be stored in the containment chamber 2 or extend out of the containment chamber 2.
[0081] In practice, the upper part of the chamber body 21 has a positioning hole that is bolted to the positioning hole below the toilet bowl 20. One side of the chamber door 22 is fixedly connected by a hinge, and the lower hinge of the chamber door 22 is fixedly connected to the pivot by bolts, thereby realizing the opening or closing of the chamber door 22. The pivot of the chamber door is bolted to the corresponding hole below the chamber body 21, and the two chamber doors 22 and the pivot of the chamber door are installed symmetrically.
[0082] In an optional embodiment, the containment chamber 2 further includes a spray head 23, which is fixedly mounted on the inner top side wall of the chamber body 21. A drain trough 211 is provided at the bottom of the chamber body 21, and a drain outlet 212 is provided at the bottom of the drain trough 211. In this embodiment, the spray head 23 is mounted on the inner top wall of the chamber body 21. When the cleaning component 12 is housed in the containment chamber 2, the spray head 23 can spray clean water, cleaning agent, or disinfectant to clean the cleaning component 12; specifically, it cleans the cloth 122 of the cleaning component 12. The wastewater after cleaning flows into the drain trough 211 and is discharged through the drain outlet 212 at the bottom of the drain trough 211.
[0083] When the cleaning device 10 for the toilet is working, the controller controls the stain detection sensor 3 to start when the human body sensor detects that there is no user in front of it. First, it collects a first feature image of the floor when there is no user. When the human body sensor detects that there is a user, the stain detection sensor 3 collects a second feature image of the floor when it is in use. The human body sensor detects once every 5 seconds. When it detects that the user has left, the stain detection sensor 3 takes a third feature image of the floor after use. The above three feature images are processed by a fusion algorithm to compare the dripping situation on the floor. If the calculation shows that the floor is clean or that a user continues to use the floor, a signal not to clean is issued.
[0084] When it is calculated that there is no user and there is dripping liquid on the ground, the controller controls the first motor 1111 and the second motor 1122 in the cleaning mechanism 1 to start. At this time, the two doors 22 of the receiving chamber 2 open, and the second motor 1122 sends the cleaning component 12 to the ground. The first motor 1111 controls the cleaning component 12 to move left and right to clean the preset area. When the cleaning component 12 cleans to the right, the first spray nozzle 1232 of the water spray component 123 sprays water to supply water to the mop 122, and the middle water suction component 124 sucks away the discharged water. When the cleaning component 12 cleans to the left, the second spray nozzle 1233 of the water spray component 123 sprays water to supply water to the mop 122, and the middle water suction component 124 sucks away the discharged water. This cycle is repeated to achieve cleaning while spraying water and sucking water at the same time.
[0085] The controller can determine the cleaning range and degree of cleaning based on the calculated ground conditions within a preset area, and then control the first motor 1111 to drive the cleaning component 12 for cleaning. During the operation of the cleaning component 12, the indicator light can flash and the speaker can play prompt music to indicate that cleaning is in progress. After the cleaning component 12 is retracted, the indicator light flashing and music playback will stop.
[0086] After the cleaning component 12 is retrieved into the containment chamber 2, the spray head 23 sprays water outward to wash the cleaning cloth 122 of the cleaning component 12. The wastewater after washing is discharged into the drain trough 211 at the bottom of the chamber 21 and discharged through the drain outlet 212 at the bottom of the drain trough 211. It can be understood that the cleaning effect of the cleaning component 12 can be maintained by regularly replacing the cleaning cloth 122.
[0087] A cleaning device for a toilet according to an embodiment of the present invention includes a cleaning mechanism, a stain detection sensor, and a controller. The stain detection sensor acquires a first feature image before a person approaches the toilet, a second feature image when the person approaches the toilet, and a third feature image after the person leaves the toilet. The controller determines whether there are stains in a preset area near the toilet based on the first, second, and third feature images sent by the stain detection sensor. When stains are present, the controller outputs a cleaning command to control the cleaning mechanism to clean the preset area. Through the stain detection sensor and controller, automatic cleaning can be performed when stains are detected in the preset area, which not only reduces the workload of cleaning personnel but also improves the timeliness of cleaning, thereby providing a cleaner hygienic environment.
