Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a cleaning mechanism and a cleaning device. Background Technology

[0002] With the popularization of smart home technology, robot vacuums with sweeping and mopping functions have become essential appliances in many households. To improve cleaning efficiency and achieve intelligent cleaning, modern robot vacuums are usually equipped with a mop dirt detection function. This function determines the cleanliness of the floor by detecting the degree of dirt on the mop, and then decides whether to return to the base station to clean the mop, whether to repeat cleaning of specific areas, or to notify the user to replace the mop, thereby significantly improving cleaning results and user experience.

[0003] Currently, mainstream mop dirt detection technologies are mainly based on optical detection principles, including transmission and reflection principles, to achieve dirt detection. By detecting the wavelength and intensity of the reflected light from the dirt on the mop, the dirt level of the cleaning area is reflected. After the dirt is carried away by the mop, it will reach the sensor at the detection end after a maximum of one rotation, which is more timely than the transmission method.

[0004] However, during operation, dirt from the mop can easily splatter onto the sensor's lens surface, causing inaccurate detection due to dirt. Currently, the common solution is to remove the mop and clean the sensor's lens surface; however, this process is cumbersome and results in a poor user experience. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a cleaning mechanism and cleaning equipment to solve the problem that when the lens surface of the sensor is contaminated, the usual method is to remove the mop to clean the lens surface of the sensor. However, this method is cumbersome to disassemble and install, resulting in a poor user experience.

[0006] To achieve the above objectives, this utility model provides a cleaning mechanism, which includes: The mounting housing has a recessed receiving space; The mop is rotatably mounted within the housing, allowing it to rotate and roll along the floor to clean it. A dirt detection mechanism is installed on the inner wall of the mounting housing for detecting dirt on the mop. In a wet state, the distance between the surface of the mop and the dirt detection mechanism is 1~10mm. In a dry state, the surface of the mop comes into contact with the dirt detection mechanism to clean the dirt detection mechanism.

[0007] Optionally, the inner wall of the mounting housing is provided with a groove to accommodate the dirt detection mechanism.

[0008] Optionally, the dirt detection mechanism is mounted on the mounting housing via a displacement adjustment mechanism, which is used to adjust the gap between the dirt detection mechanism and the mop.

[0009] Optionally, the displacement adjustment mechanism includes: A limiting mechanism is provided on the mounting housing and connected to the dirt detection mechanism to limit the displacement of the dirt detection mechanism; A pushing mechanism, disposed on the mounting housing and in contact with the dirt detection mechanism, is used to generate thrust to adjust the gap between the dirt detection mechanism and the mop.

[0010] Optionally, the limiting mechanism includes: At least two mounting cylinders are spaced apart on the inner wall of the mounting housing, and each mounting cylinder is provided with an elastic mechanism that can extend under tension. At least two pull rods are provided, with one pull rod inside each of the mounting cylinders. One end of each pull rod is connected to the elastic mechanism, and the other end is connected to the dirt detection mechanism.

[0011] Optionally, the elastic mechanism is a spring, rubber, or silicone.

[0012] Optionally, the actuation mechanism includes: A rotating shaft is rotatably mounted on the mounting housing. At least one cam is provided on the rotating shaft. The cam contacts the dirt detection mechanism. The rotating shaft drives the cam to rotate and generate thrust to adjust the gap between the dirt detection mechanism and the mop. A drive motor is mounted on the mounting housing, and the drive shaft of the drive motor is connected to the rotating shaft to drive the rotating shaft to rotate.

[0013] Optionally, a wear-resistant plate is provided at the position where the dirt detection mechanism contacts the cam.

[0014] Optionally, the mounting housing is provided with at least one threaded hole; The pushing mechanism includes: at least one screw located in the corresponding threaded hole, the adjusting end of the screw located outside the mounting housing, and the connecting end of the screw connected to the dirt detection mechanism via a bearing. By rotating the screw, the gap between the dirt detection mechanism and the mop can be adjusted.

[0015] On the other hand, this utility model provides a cleaning device, the cleaning device comprising: Organism; The aforementioned cleaning mechanism is mounted on the machine body.

[0016] This technical solution utilizes the property that the diameter of the mop is larger when dry than when wet to optimize the setting distance between the mop and the dirt detection mechanism. This allows the mop to come into contact with the dirt detection mechanism when dry, achieving self-cleaning of the dirt detection mechanism without disassembling the mop, ensuring the accuracy of the dirt detection mechanism and improving the user experience.

Detailed Implementation

[0020] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0021] In this embodiment of the utility model, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use.

[0022] The terms “first,” “second,” “third,” etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0023] The terms "parallel" and "perpendicular" do not mean that the components must be absolutely parallel or perpendicular, but rather that they can be slightly tilted. For example, "parallel" simply means that its direction is more parallel than "perpendicular," not that the structure must be completely parallel, but that it can be slightly tilted.

[0024] The terms "horizontal," "vertical," and "sag" do not imply that a component must be absolutely horizontal, vertical, or sagging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

[0025] Furthermore, terms like "roughly" and "basically" are used to indicate that the content does not require absolute precision, but rather allows for a certain degree of deviation. For example, "roughly equal" does not simply mean absolute equality; in actual production and operation, achieving absolute "equality" is difficult, and a certain degree of deviation is generally present. Therefore, besides absolute equality, "roughly equal to" also includes the aforementioned situation where a certain degree of deviation exists. Using this as an example, in other cases, unless otherwise specified, terms like "roughly" and "basically" have similar meanings.

[0026] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Example 1: like Figure 1 As shown, this embodiment provides a cleaning mechanism, which includes: Mounting housing 1 has a recessed receiving space; The mop 2 is rotatably mounted in the housing 1 and can rotate and roll to clean the floor. The dirt detection mechanism 3 is installed on the inner wall of the mounting housing 1 and is used to detect dirt on the mop 2; In a wet state, the distance between the surface of the mop 2 and the dirt detection mechanism 3 is 1~10mm. In a dry state, the surface of the mop 2 comes into contact with the dirt detection mechanism 3 to clean the dirt detection mechanism 3.

[0029] Specifically, in this embodiment, the mounting housing 1 has a concave, semi-enclosed receiving space. The mop 2 is disposed at the open end of the receiving space, with most of it located within the space and the remainder in contact with the ground. The mop 2 is mounted on a roller or track, and the motor outputs rotational power to drive the roller or track to rotate, thereby rotating the mop 2 and cleaning the ground. Simultaneously, a dirt detection mechanism 3 is disposed within the receiving space of the mounting housing 1 to detect dirt on the mop 2. The ambient light within the receiving space is relatively fixed, reducing the impact of the external environment on the detection results. Furthermore, this technical solution utilizes the property that the mop 2 has a larger diameter when dry than when wet to optimize the distance between the mop 2 and the dirt detection mechanism 3. This allows the mop 2 to contact the dirt detection mechanism 3 when dry, achieving self-cleaning of the mechanism without disassembling the mop 2, ensuring the accuracy of the dirt detection and improving the user experience. Specifically, the distance between the surface of the mop 2 and the dirt detection mechanism 3 is in the range of 1 to 10 mm. The specific distance can be determined based on the fluffiness of the mop 2 from its wet to its dry state. For example, for a mop 2 that is almost not fluffi from wet to dry, the distance between the surface of the mop 2 and the dirt detection mechanism 3 can be set to a minimum of 1 mm; for a mop 2 that becomes significantly fluffier from wet to dry, the distance between the surface of the mop 2 and the dirt detection mechanism 3 can be set to a maximum of 10 mm. Preferably, in the wet state, the distance between the surface of the mop and the dirt detection mechanism is 3 to 5 mm.

[0030] In one implementation, such as Figure 2 As shown, the dirt detection mechanism 3 of the cleaning system is configured to include a PCB board 31 and at least one diode group 32 disposed on the PCB board 31. Each diode group 32 includes one emitting diode 321 and two receiving diodes 322. The two receiving diodes 322 are spaced apart on both sides of the emitting diode 321. The emitting diode 321 emits a signal, and the two receiving diodes 322 receive it, increasing the detection area and achieving a high-density array arrangement of diodes. The structure is compact, with small overall vertical structural space requirements, optimizing the structural dimensions. Furthermore, the detection of the corresponding area of ​​the mop 2 is achieved through a single diode group 32, resulting in low cost per unit detection area and easy cleaning. In addition, to optimize the vertical structural space requirements, a recessed mounting groove is provided on the inner wall of the mounting housing 1, and the dirt detection mechanism 3 is disposed within this mounting groove.

[0031] More specifically, the mounting housing 1, the mop 2, and the PCB board 31 all have a certain length. The diode group 32 set on the PCB board 31 is arranged in sequence along the length direction and is aligned with the mop 2. The center of the diode group 32 is an RGB emitting diode 321, and the two sides are red light receiving diodes 322. The degree of dirtiness is judged by detecting the wavelength and intensity of the light reflected by the mop.

[0032] More specifically, such as Figure 4 As shown, PCB board 31 is equipped with a microprocessor unit, signal conversion circuit, amplification and filtering circuit, analog-to-digital conversion circuit, counter, and other circuit structures. The on / off timing of the emitting LEDs is controlled by the microprocessor unit. The receiving LEDs can be a single monochromatic LED in an unbiased or reverse-biased state, or one or more multi-color LEDs. Their photoelectric signals are converted into current, voltage, and time signals by the signal conversion circuit. For the converted current and voltage signals, the weak signals are first amplified and noise filtered by the amplification and filtering circuit, and then converted into digital signals that the microprocessor can process by the analog-to-digital conversion circuit. For the converted time signals, they are first converted into digital signals that the microprocessor can process by the counter. The microprocessor further processes the collected signals and outputs the current dirt status of the mop. The microprocessor unit, signal conversion circuit, amplification and filtering circuit, analog-to-digital conversion circuit, counter, and other circuit structures are all structures and working principles known to those skilled in the art, and are all prior art, which will not be described in detail here.

[0033] More specifically, in one implementation, 31 RGB LEDs are used as the transmitters. The MCU controls the lighting of only one RGB LED at a time, emitting one of the three colors. Experiments have shown that red LEDs are sensitive to both RGB light; therefore, this scheme can use 64 parallel red LEDs (two red LEDs arranged on either side of each RGB LED) without bias voltage as the receivers. The photocurrent is converted into a voltage signal using a transimpedance amplifier (TIA). To reduce the influence of AC mains power on the detection signal, the voltage signal converted by the TIA is fed into a dual-T network notch filter with a center frequency of 50Hz. After filtering, the signal is further amplified by a differential amplifier and then fed into the ADC on the MCU. The MCU is responsible for reading and processing the ADC output signal, and, combined with the currently lit RGB LED sequence number and color, calculating the level of dirt in a specific detection area.

[0034] In one embodiment, by providing a groove 101 on the inner wall of the mounting housing 1 and placing the dirt detection mechanism 3 in the groove 101 of the mounting housing, the longitudinal structural space requirement can be effectively reduced, so as to optimize the overall layout.

[0035] In one implementation, such as Figure 1 As shown, the cleaning mechanism also includes a spraying component 4 and a scraping component 5, both mounted on the mounting housing 1. The liquid can be water, disinfectant, cleaning solution, etc. The spraying component 4 sprays liquid onto the mop 2, cleaning the mop 2. After spraying the liquid, the scraping component 5 scrapes off the liquid from the mop 2, preventing dirt from the mop 2 from re-contaminating the ground after it rotates and contacts the floor, thus ensuring effective cleaning. More specifically, the spraying component 4 includes a delivery pipe and a nozzle. A through hole is formed in the mounting housing 1, and the nozzle is mounted on the inner surface of the mounting housing 1. The delivery pipe passes through the through hole and connects to the nozzle. Alternatively, the nozzle can be mounted on the outer surface of the mounting housing 1, passing through the through hole towards the mop. The delivery pipe connects to the nozzle, and a liquid tank supplies liquid to the nozzle through the delivery pipe. The liquid is then sprayed evenly onto the surface of the mop 2. The liquid tank is mounted on the body of the cleaning equipment and connected to the delivery pipe. The scraping component 5 includes a scraper and a collection tank. The collection tank is mounted on the mounting housing 1, and the scraper is mounted on the collection tank. The scraper is the same length as the mop and contacts the surface of the mop 2 when scraping is required. When the mop 2 rotates, the scraper scrapes the liquid off the surface of the mop 2 and it flows into the collection tank. In addition, in order to collect waste liquid, a waste liquid tank is provided on the body of the cleaning equipment, and a through hole is provided on the collection tank. Waste liquid is transported to the waste liquid tank for temporary storage through a pipe.

[0036] In one embodiment, the dirt level on the surface of the mop 2 is first detected by the dirt detection mechanism 3, and then the amount of liquid sprayed by the spraying component 4 is determined based on the dirt level on the surface of the mop 2. Then, the liquid is scraped off the mop 2 by the scraping component 5. Therefore, by setting the dirt detection mechanism 3, the spraying component 4 and the scraping component 5 in sequence according to the rotation direction of the mop 2, the cleaning effect on the mop 2 is further guaranteed.

[0037] In another embodiment, the dirt detection mechanism 3, the spraying component 4, and the scraping component 5 are arranged in a triangular structure. The spraying component 4 is positioned above the mop 2, and the dirt detection mechanism 3 and the scraping component 5 are positioned on opposite sides of the mop 2. The liquid is sprayed and scraped more effectively by utilizing its own gravity, thus optimizing the overall layout and ensuring cleaning results.

[0038] In one implementation, such as Figure 3 As shown, the cleaning mechanism also includes a sterilization and disinfection mechanism 6, which is installed on the inner wall of the mounting housing 1 and is used to sterilize and disinfect the mop. Since the mop 2 is prone to the growth of bacteria, viruses, and other microorganisms during and after cleaning the floor, the sterilization and disinfection mechanism 6 is installed on the inner wall of the mounting housing 1 to sterilize and disinfect the mop 2, achieving better cleaning results and quality, and improving user satisfaction.

[0039] Preferably, the sterilization and disinfection mechanism 6 is configured with at least one UVC band ultraviolet light-emitting diode (UVLED). The UVLED continuously irradiates the mop 2 at close range, achieving sterilization and disinfection of the mop 2. In this design, at least one diode group 32 is provided on the PCB board 31. Each diode group 32 includes one emitting diode 321 and two receiving diodes 322 spaced apart on either side of the emitting diode 321, achieving a high-density array arrangement and compact structure. Since the PCB board 31 still has additional mounting space, the UVLED is also placed on the PCB board 31. Specifically, the diode group 32 and the UVLED are arranged alternately in a straight line to ensure that the UV light emitted by the UVLED completely covers the mop 2. Furthermore, to avoid the influence of UV light on the dirt detection results, the UVLED only starts working after each cleaning cycle is completed, performing sterilization and disinfection.

[0040] In one implementation, such as Figure 5 Figures (a) and (b) show schematic diagrams illustrating the positional relationship between the mop 2 and the dirt detection mechanism 3 in both wet and dry states on the roller, and, respectively. Figure 6 Figures (a) and (b) illustrate the positional relationship between the mop 2 and the dirt detection mechanism 3 in wet and dry states, respectively. During the cleaning process, when the mop 2 is wetted, its overall diameter or height decreases. At this time, the mop 2 does not contact the lenses of the emitting diode 321 and the receiving diode 322. In the dry state, the mop 2 becomes fluffy, its overall diameter or height increases, and it comes into contact with the lens surfaces of the emitting diode 321 and the receiving diode 322. Through friction, it achieves self-cleaning of the lens surfaces of the emitting diode 321 and the receiving diode 322, thus ensuring the effectiveness of dirt detection. Specifically, the cleaning effect can be ensured by controlling the rotation of the mop 2.

[0041] In one embodiment, after a period of use, the mop 2 will wear down. Even when the mop 2 is dry, this will increase the gap between the mop 2 and the emitting diode 321 and receiving diode 322, resulting in poor contact and ineffective cleaning. Therefore, in this embodiment, a displacement adjustment mechanism 7 is provided to adjust the gap between the dirt detection mechanism 3 and the mop 2. After the mop 2 has been used for a period of time, the displacement adjustment mechanism 7 adjusts the extension of the dirt detection mechanism 3, thereby adjusting the gap between the dirt detection mechanism 3 and the mop 2. This ensures that the mop 2, when dry, can contact the lens surfaces of the emitting diode 321 and receiving diode 322, improving the cleaning effect and ensuring the accuracy of dirt detection.

[0042] In one embodiment, the PCB board 31 is integrated into the protective housing, and the displacement adjustment mechanism 7 is connected to the protective housing, thereby ensuring that the protective housing bears the force during the adjustment of the gap between the dirt detection mechanism 3 and the mop 2, so as to protect the PCB board 31 and the diode group 32 and increase the service life.

[0043] In one embodiment, for a certain type of mop 2, the diameter is 45.5 mm in the wet state and 51.6 mm in the dry state, with a difference of 6.1 mm between the wet and dry states. Therefore, the optimal distance between the lens surfaces of the emitting diode 321 and the receiving diode 322 and the surface of the wet mop 2 is about 3 to 5 mm.

[0044] In another embodiment, the displacement adjustment mechanism 7 can be set in the groove of the mounting housing, thereby effectively reducing the longitudinal structural space requirement.

[0045] In one implementation, such as Figure 7 As shown, the displacement adjustment mechanism 7 includes: The limiting mechanism 71 is installed on the inner wall of the mounting housing 1 and connected to the dirt detection mechanism 3 to limit the displacement of the dirt detection mechanism 3. The pushing mechanism 72 is disposed on the inner wall of the mounting housing 1 and contacts the dirt detection mechanism 3. It is used to generate thrust to adjust the gap between the dirt detection mechanism 3 and the mop 2.

[0046] Specifically, to ensure normal dirt detection and reduce the displacement of the dirt detection mechanism 3 during the detection process, which could lead to inaccurate results, the dirt detection mechanism 3 needs to be in a fixed state. Therefore, a limiting mechanism 71 is provided to fix the dirt detection mechanism 3. In addition, to achieve displacement adjustment of the dirt detection mechanism 3 (adjustment of the amount of protrusion of the dirt detection mechanism 3 relative to the inner wall of the mounting housing 1) so that the dirt detection mechanism 3 can be closer to the mop 2, a pushing mechanism 72 is provided on the mounting housing 1 to generate an outward pushing force, pushing the dirt detection mechanism 3 to move outward. With the limiting mechanism 71 limiting and the pushing mechanism 72 generating a pushing force, the two work together to not only meet the requirements of stable fixation of the dirt detection mechanism 3 in daily use, effectively reducing shaking, but also to adjust the displacement of the dirt detection mechanism 3 (i.e., the amount of protrusion of the dirt detection mechanism 3 relative to the inner wall of the mounting housing 1) when needed.

[0047] In one implementation, such as Figure 9 As shown, the limiting mechanism 71 is configured to include: At least two mounting cylinders 711 are spaced apart on the inner wall of the mounting housing 1. Each mounting cylinder 711 is provided with an elastic mechanism 712, which can extend under tension. There are at least two pull rods 713. Each mounting cylinder 711 is equipped with one pull rod 713. One end of the pull rod 713 is connected to the elastic mechanism 712, and the other end is connected to the dirt detection mechanism 3.

[0048] Specifically, in this embodiment, the mounting cylinder 711 is hollow inside, and its fixed end is directly fixed to the inner wall of the mounting housing 1 via a first connecting piece. Simultaneously, an elastic mechanism 712 is provided inside the mounting cylinder 711. One end of the elastic mechanism 712 is fixed inside the mounting cylinder 711, and the other end is connected to a pull rod 713. The end of the pull rod 713 connected to the elastic mechanism 712 is always located inside the mounting cylinder 711, and the other end of the pull rod 713 is connected to the dirt detection mechanism 3 via a second connecting piece. In this way, the elastic mechanism 712 always generates a pulling force, pulling the pull rod 713 inward, thereby limiting the dirt detection mechanism 3. Furthermore, to ensure that the dirt detection mechanism 3 does not shake or vibrate, matching grooves and protrusions are provided on the mounting cylinder 711 and the pull rod 713 respectively (e.g., a slot is provided on the outer wall of the pull rod 713, and a protrusion is provided on the inner wall of the mounting cylinder 711, with the protrusion always located in the slot), achieving radial limiting. Furthermore, the first and second connecting pieces are provided with connecting holes, and are fixed by screws passing through the connecting holes respectively. The first and second connecting pieces can also increase the contact area, thereby ensuring the stability of the connection.

[0049] Preferably, the PCB board 31 in the dirt detection mechanism 3 adopts a rectangular structure. To ensure that the dirt detection mechanism 3 does not shake or vibrate, resulting in inaccurate dirt detection, four mounting cylinders 711 are provided, and the four mounting cylinders 711 are distributed in a rectangular structure, respectively fixedly connected to the four corners of the PCB board 31, thereby increasing the overall stability. In addition, to achieve modular installation, the fixed ends of all mounting cylinders 711 are mounted on a connecting plate, and then the connecting plate is fixed to the inner wall of the mounting housing 1 for quick installation and disassembly.

[0050] Preferably, the elastic mechanism 712 is made of spring, rubber or silicone, which has a certain elastic deformation capability, so that when the dirt detection mechanism 3 is pushed outward by the pushing mechanism 72, it can generate a reverse inward pulling force to ensure the stability of the dirt detection mechanism 3.

[0051] In one implementation, such as Figure 10 As shown, the driving mechanism 72 includes: A rotating shaft 721 is rotatably mounted on the mounting housing 1. At least one cam 722 is provided on the rotating shaft 721. The cam 722 contacts the dirt detection mechanism 3. The rotating shaft 721 drives the cam 722 to rotate, generating thrust. A drive motor 723 is mounted on the mounting housing 1. The drive shaft of the drive motor 723 is connected to the rotating shaft 721 and is used to drive the rotating shaft 721 to rotate.

[0052] Specifically, in this embodiment, the cam 722 is positioned on the back side of the dirt detection mechanism 3, meaning it is pushed from the back side of the dirt detection mechanism 3 to adjust the gap between the dirt detection mechanism 3 and the mop 2. A mounting hole is provided on the mounting housing 1, and the rotating shaft 721 is installed through the mounting hole, allowing the rotating shaft 721 to rotate. Furthermore, at least one cam 722 (e.g., an elliptical structure) is provided on the rotating shaft 721, and the cam 722 is always in contact with the dirt detection mechanism 3, thereby restricting the position of the dirt detection mechanism 3. Under normal circumstances, the part corresponding to the smallest outer diameter of the cam 722 is in contact with the dirt detection mechanism 3. When it is necessary to push the dirt detection mechanism 3 outward, the rotating shaft 721 drives the cam 722 to rotate, causing the diameter of the contact part to gradually increase, increasing the outward thrust. When the part with the largest diameter of the cam 722 is in contact with the dirt detection mechanism 3, the thrust applied to the dirt detection mechanism 3 is the largest, and at this time, the displacement of the dirt detection mechanism 3 is also the largest. Preferably, in this embodiment, a drive motor 723 is used to apply rotational force to the rotating shaft 721 to achieve rapid and precise adjustment.

[0053] In another embodiment, in order to protect the dirt detection mechanism 3, a wear-resistant plate is provided at the position where the dirt detection mechanism 3 contacts the cam 722 to reduce friction and prevent wear on the dirt detection mechanism 3 (PCB board 31).

[0054] In another implementation, such as Figure 8 As shown, an external power source (manual adjustment, external motor drive, etc.) is used to adjust the gap between the dirt detection mechanism 3 and the mop 2. At least one threaded hole is provided on the mounting housing 1; and the pushing mechanism 52 includes at least one screw 724 located in the corresponding threaded hole. The adjusting end of the screw 724 is located outside the mounting housing 1 and is provided with slotted, Phillips, and perforated grooves to adapt to the corresponding parts and achieve rapid adjustment. The connecting end of the screw 724 is connected to the dirt detection mechanism 3 through a bearing 725. By rotating the screw 724, the screw 724 can be extended relative to the mounting housing 1. At this time, the screw 724 pushes the dirt detection mechanism 3 to adjust the gap between the dirt detection mechanism 3 and the mop 2. More specifically, the end of the screw 724 is connected to the dirt detection mechanism 3 via a bearing 725. That is, the inner ring of the bearing 725 is connected to the end of the screw 724, and the outer ring of the bearing 725 is connected to the dirt detection mechanism 3. This converts rotation into linear movement, which can improve the stability of the contact area between the screw 724 and the dirt detection mechanism 3 and reduce vibration.

[0055] In another embodiment, when the cam 722 and the dirt detection mechanism 3 are positioned vertically on the same side, the rotating shaft 721 is rotatably mounted on the mounting housing 1. At least one cam 722 is mounted on the rotating shaft 721. The cam 722 contacts the dirt detection mechanism 3 via a lever (i.e., the first end of the lever contacts the cam 722, and the second end of the lever contacts the dirt detection mechanism 3). The lever is rotatably mounted on the mounting housing 1 via a rotating shaft. When the rotating shaft 721 is used, it drives the cam 722 to rotate, pushing the first end of the lever. At this time, the second end of the lever moves in the opposite direction to the movement of the first end, thereby pushing the dirt detection mechanism 3 to move, and thus adjusting the gap between the dirt detection mechanism 3 and the mop 2. Specifically, a drive motor 723 is mounted on the mounting housing 1, and the drive shaft of the drive motor 723 is connected to the rotating shaft 721 to drive the rotating shaft 721 to rotate.

[0056] In another embodiment, besides using a drive motor 723 to generate driving force for rotation adjustment, manual adjustment can also be used. In this case, there is no need to set up a drive motor 723; instead, the rotating shaft 721 is driven to rotate by external force. The rotating shaft 721 is connected to the inner wall of the mounting housing 1 through a ratchet mechanism. Specifically, a ratchet is provided on the drive shaft 721, and an active pawl and a non-active pawl are provided at corresponding positions on the inner wall of the mounting housing 1. Both the active pawl and the non-active pawl are inserted into the tooth grooves of the ratchet to achieve engagement and limiting of the rotating shaft 721, so that the rotating shaft 721 only has the ability to rotate in one direction, maintaining the current outward pushing state.

[0057] Example 2: This embodiment also provides a cleaning device, which includes: Organism; The aforementioned cleaning mechanism is mounted on the machine body.

[0058] Specifically, in this embodiment, the cleaning equipment's body includes: a movement mechanism (such as wheels to enable movement), a dust collection and removal mechanism (such as for storing and processing waste), a sensing and navigation system (such as radar and various sensors to collect data on itself and the environment, providing data support for control), an energy system (such as a battery to provide the electrical energy required for the entire cleaning equipment), and a control center (such as a main controller to integrate all sensor data, run path planning algorithms (such as SLAM), and control all actuators (motors, wheels, brushes, etc.) to work together). Simultaneously, the aforementioned cleaning mechanisms are installed at corresponding positions on the body, enabling the cleaning of the floor. More specifically, the cleaning equipment can be a robotic vacuum cleaner, a floor scrubber, a vacuum cleaner, or other similar devices.
