Description

Technical Field

[0001] This utility model relates to the field of window cleaning machine technology, specifically a window cleaning machine with corner cleaning function. Background Technology

[0002] With the advancement of urban modernization and the increasing number of high-rise buildings, the demand for cleaning large glass windows is becoming increasingly prominent. People use window cleaning machines to meet the needs of efficient and safe window cleaning. Existing square window cleaning machines generally adopt a four-corner drop bar structure design, but this structure makes it difficult for window cleaning machines to effectively clean the corners when cleaning framed windows. The presence of the frame restricts the range of motion of the window cleaning machine, preventing it from getting close enough to the corners for thorough cleaning, thus leaving cleaning dead corners. These dead corners not only affect the cleaning effect of the windows, but may also lead to the long-term accumulation of dust and stains, thereby affecting the overall aesthetics of the building and the hygiene of the indoor environment.

[0003] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0004] Regarding the aforementioned issue that existing window cleaning machines generally employ a four-corner drop bar structure, the presence of the frame restricts the machine's range of motion when cleaning windows with frames, preventing it from fully reaching the corners and leaving cleaning blind spots. The technical solution adopted by this invention to solve this problem is: A window cleaning machine with corner cleaning function includes a body, corner wheels disposed at the corners of the body, a cleaning component located at the bottom of the body, an anti-fall mechanism connected to the body, and an optical coupler detection mechanism. The anti-fall mechanism and the corner wheels can move relative to the optical coupler detection mechanism so that the optical coupler detection mechanism can detect the working status of the window cleaning machine. The cleaning component includes a first cleaning element disposed at the bottom of the corner wheel, and the anti-fall mechanism drives the corner wheel to push the first cleaning element to fit into the cleaning area.

[0005] Furthermore, the corner wheel has a mounting groove on the side near the cleaning area, and the mounting groove is provided with Velcro, through which the first cleaning component is installed into the mounting groove.

[0006] Furthermore, the first cleaning component is a lint-covered cleaning cloth, and the corner wheel includes a cleaning end face located at the end, with the first cleaning component protruding relative to the cleaning end face.

[0007] Furthermore, the bottom of the machine body is provided with a mounting panel, and the cleaning component includes a second cleaning element that is detachably disposed on the side of the mounting panel near the cleaning area.

[0008] Furthermore, the anti-fall mechanism includes an anti-fall top cover connected to the optocoupler detection mechanism, a first elastic reset member, and an anti-fall rod. A support bracket is provided between the anti-fall top cover and the anti-fall rod. The anti-fall rod passes through the support bracket and is connected to the anti-fall top cover. One side of the first elastic reset member abuts against the anti-fall rod, and the other side abuts against the inner wall of the support bracket.

[0009] Furthermore, the anti-fall cover includes a light-shielding part extending toward the optical coupler detection mechanism. The optical coupler detection mechanism includes an optical coupler support plate, an optical coupler input end and an optical coupler output end disposed opposite to each other on the optical coupler support plate. The light-shielding part is located between the optical coupler input end and the optical coupler output end and changes its light-shielding state on the optical coupler input end and the optical coupler output end as the anti-fall cover is displaced.

[0010] Furthermore, the support bracket includes a first support portion connected to the anti-fall top cover, and a second support portion connected to the first support portion and extending toward the first cleaning component. The corner walking wheel is sleeved on the outer wall of the second support portion, and a second elastic reset component is provided between the first support portion and the inner wall of the machine body.

[0011] Furthermore, the outer wall of the anti-fall rod is provided with several limiting protrusions, and the inner wall of the support bracket is provided with several limiting grooves that engage with the limiting protrusions.

[0012] Furthermore, the light-shielding part is integrally formed on the anti-fall top cover.

[0013] Furthermore, the portion of the first cleaning component that protrudes relative to the cleaning end face is H. When the first cleaning component is in a fully compressed state, H=0; when the machine body is in a moving state, 0.5mm≤H≤1mm; when the machine body is in a non-working state, 1mm≤H≤2mm.

[0014] The beneficial effects of this utility model are as follows: 1. This utility model provides a first cleaning component at the bottom of the corner walking wheels. Since the corner walking wheels are located at the four corners of the machine body, which are closest to the window frame, the first cleaning component can clean the corner area of ​​the window when the right angle of the machine body corresponds to the right angle of the window frame. In addition, the anti-fall mechanism drives the corner walking wheels to push the first cleaning component to fit the cleaning area, which helps to ensure that the first cleaning component is in full contact with the window surface. Applying appropriate pressure during the cleaning process, the first cleaning component can fit tightly against the glass, which helps to improve cleaning efficiency and effect. This effectively solves the problem that existing window cleaning machines generally use a four-corner drop bar structure. However, when cleaning windows with frames, the presence of the frame restricts the range of motion of the window cleaning machine, causing the window cleaning machine to be unable to fully get close to the corners for cleaning, thus leaving cleaning dead corners. 2. Both the anti-fall mechanism and the corner wheels can move relative to the optical coupler detection mechanism. The optical coupler detection mechanism can detect the working status of the window cleaning machine. During the operation of the window cleaning machine, the optical coupler detection mechanism can monitor the relative position of the corner wheels and the anti-fall mechanism in real time. When an abnormality is detected, the window cleaning machine can make corresponding adjustments in a timely manner, which helps to improve the stability of the window cleaning machine.

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0017] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0018] like Figures 1 to 8 The window cleaning machine shown includes a body 1, corner wheels 2 disposed at the corners of the body 1, a cleaning component 3 located at the bottom of the body 1, an anti-fall mechanism 4 connected to the body 1, and an optical coupler detection mechanism 5. The anti-fall mechanism 4 and the corner wheels 2 can move relative to the optical coupler detection mechanism 5 so that the optical coupler detection mechanism 5 can detect the working status of the window cleaning machine. The cleaning component 3 includes a first cleaning element 31 disposed at the bottom of the corner wheel 2, and the anti-fall mechanism 4 drives the corner wheel 2 to push the first cleaning element 31 to fit into the cleaning area. This invention features a first cleaning component at the bottom of the corner wheels. Since these wheels are located at the four corners of the machine body, which are closest to the window frame, the first cleaning component can clean the corner areas of the window when the right angle of the machine body aligns with the right angle of the window frame. Furthermore, the anti-fall mechanism drives the corner wheels to push the first cleaning component against the cleaning area, ensuring full contact between the first cleaning component and the window surface. Applying appropriate pressure during the cleaning process allows the first cleaning component to adhere tightly to the glass, improving cleaning efficiency and effectiveness. This effectively solves the problem that existing window cleaning machines commonly use a four-corner drop bar structure, which restricts the machine's range of motion when cleaning windows with frames, preventing the machine from fully approaching the corners and leaving cleaning dead zones.

[0019] Furthermore, both the anti-fall mechanism 4 and the corner wheels 2 can move relative to the optical coupler detection mechanism 5. The optical coupler detection mechanism 5 can detect the working status of the window cleaning machine. During the operation of the window cleaning machine, the optical coupler detection mechanism 5 can monitor the relative position of the corner wheels 2 and the anti-fall mechanism 4 in real time. When an abnormality is detected, the window cleaning machine can make corresponding adjustments in a timely manner, which is conducive to improving the stability of the window cleaning machine.

[0020] Furthermore, by setting up an optocoupler detection mechanism 5 to detect the working status of the window cleaning machine, compared with the traditional current detection method, the optocoupler detection mechanism 5 can greatly improve the detection sensitivity, which is conducive to enhancing the safety of the machine body 1 during use.

[0021] like Figures 1 to 8 The corner wheel 2 shown is provided with a mounting groove 21 on the side near the cleaning area. The mounting groove 21 is provided with Velcro 22, and the first cleaning component 31 is installed into the mounting groove 21 through the Velcro 22. Furthermore, during the use of the window cleaning machine, the first cleaning component 31 will gradually wear down or become stained with a lot of dirt as the cleaning work progresses. When it reaches a certain level, it needs to be replaced. The first cleaning component 31 is installed into the mounting groove 21 of the corner walking wheel 2 using Velcro 22, which makes the replacement operation simple. The user only needs to peel off the Velcro 22 to remove the old first cleaning component 31 from the mounting groove 21, and then stick the new first cleaning component 31 into the mounting groove 21 using Velcro 22. Compared with traditional fixed installation methods, such as screw fixing and glue sticking, it helps to save the time and effort required to replace the first cleaning component 31 and effectively improves the efficiency of the window cleaning machine.

[0022] Furthermore, the Velcro 22 provides a tighter adhesive effect, which helps to ensure that the first cleaning component 31 is securely installed in the mounting groove 21 of the corner travel wheel 2. During the operation of the window cleaning machine, the first cleaning component 31 will not easily loosen or shift, and can always be tightly attached to the cleaning area, thereby more effectively removing dust, stains, etc., and helping to improve the cleaning quality.

[0023] Furthermore, the Velcro 22 has good durability and can be attached and detached multiple times without affecting its adhesive performance, so that the first cleaning component 31 can be installed and removed multiple times. When the first cleaning component 31 is worn or needs to be cleaned, it can simply be removed for replacement or cleaned and reinstalled, without the need to frequently replace the Velcro 22, thus reducing the cost of use.

[0024] like Figures 1 to 8 The first cleaning component 31 shown is a cleaning cloth with a velvet lining. The corner wheel 2 includes a cleaning end face 23 located at the end. The first cleaning component 31 protrudes from the cleaning end face 23. Furthermore, the fuzzy cleaning cloth has a large number of fine fibers that increase the contact area with the window surface, thus more effectively absorbing dust, stains, and fine particles. Compared to ordinary smooth cleaning cloths, the fuzzy structure can penetrate into the tiny crevices of the window surface to clean out hidden dirt, greatly improving the thoroughness of cleaning.

[0025] Furthermore, the fuzzy cleaning cloth increases friction with the window surface, allowing the window cleaning machine to more effectively wipe away dirt as it moves, reducing slippage during the cleaning process, helping the window cleaning machine complete the cleaning task more quickly, and improving overall work efficiency.

[0026] Furthermore, since the cleaning cloth with fluff has compression properties and is slightly higher than the cleaning end face 23, when the window cleaning machine moves to the cleaning area, the cleaning cloth can be quickly compressed after being subjected to the pressure of the glass surface, which will not hinder the movement of the anti-fall mechanism 4. This allows the anti-fall mechanism 4 to still work normally during the glass cleaning process, while the cleaning cloth can also fit tightly with the glass to achieve efficient cleaning.

[0027] Optionally, in some embodiments, the first cleaning element 31 can be a cleaning sponge. The sponge structure of the cleaning element has good water absorption and softness, can absorb a large amount of cleaning liquid, and at the same time, it causes less friction to the glass surface during the cleaning process, making it suitable for cleaning relatively fragile glass surfaces.

[0028] like Figures 1 to 8 The bottom of the body 1 shown is provided with a mounting panel 11, and the cleaning component 3 includes a second cleaning component 32 that is detachably disposed on the side of the mounting panel 11 near the cleaning area; Furthermore, the detachable design allows users to easily remove the second cleaning component 32 from the mounting panel 11 for cleaning, replacement, or maintenance, greatly reducing maintenance time and improving the efficiency of the window cleaning machine.

[0029] Optionally, the connection between the mounting panel 11 and the second cleaning component 32 can be achieved by threaded connection, snap-fit ​​connection, Velcro connection, or other connection methods.

[0030] Preferably, the second cleaning component 32 is a cleaning cloth with a fuzzy surface.

[0031] Furthermore, by placing the second cleaning component 32 on the mounting panel 11 at the bottom of the machine body 1, it can be ensured that the second cleaning component 32 cleans the glass surface in a large area and evenly during the movement of the window cleaning machine, so that the cleaning component 3 can cover the entire glass surface, not just the corner areas, thereby improving the overall cleaning efficiency.

[0032] Furthermore, the second cleaning component 32 on the side of the mounting panel 11 closest to the cleaning area can play a buffering and protective role to a certain extent. When the window cleaning machine moves on the glass surface, the second cleaning component 32 comes into contact with the glass first, which can reduce the wear and impact of uneven glass surface or small particles on other parts of the window cleaning machine.

[0033] like Figures 1 to 8The anti-fall mechanism 4 shown includes an anti-fall top cover 41 connected to the optocoupler detection mechanism 5, a first elastic reset member 42, and an anti-fall rod 43. A support bracket 6 is provided between the anti-fall top cover 41 and the anti-fall rod 43. The anti-fall rod 43 passes through the support bracket 6 and is connected to the anti-fall top cover 41. One side of the first elastic reset member 42 abuts against the anti-fall rod 43, and the other side abuts against the inner wall of the support bracket 6. Specifically, the first elastic reset member 42 is arranged along a first direction, which is perpendicular to the surface of the cleaned glass. The anti-fall mechanism 4 is connected to the corner travel wheel 2, and the anti-fall mechanism 4 is correspondingly arranged with the corner travel wheel 2. The corner travel wheel 2 is sleeved on the outer wall of the support bracket 6. When the corner travel wheel 2 moves, it drives the support bracket 6 to move. The anti-fall rod 43 passes through the support bracket 6 and is connected to the anti-fall top cover 41, so that the support bracket 6 can drive the anti-fall rod 43 to move. During the movement, the anti-fall rod 43 drives the anti-fall top cover 41 to move relative to the optical coupler detection mechanism 5 along the first direction, thereby enabling the optical coupler detection mechanism 5 to identify the working state of the window cleaning machine in the first direction. Secondly, one end of the first elastic reset member 42 abuts against the anti-fall rod 43, and the other end abuts against the inner wall of the support bracket 6. When the window cleaning machine leaves the cleaning area, under the action of the first elastic reset member 42, the anti-fall rod 43 automatically resets and drives the anti-fall top cover 41 to reset, thereby entering the disengagement state.

[0034] like Figures 1 to 8 The anti-fall cover 41 shown includes a light-shielding part 411 extending toward the optical coupler detection mechanism 5. The optical coupler detection mechanism 5 includes an optical coupler support plate 51, an optical coupler input terminal 52 and an optical coupler output terminal 53 disposed opposite to each other on the optical coupler support plate 51. The light-shielding part 411 is located between the optical coupler input terminal 52 and the optical coupler output terminal 53 and changes its light-shielding state on the optical coupler input terminal 52 and the optical coupler output terminal 53 as the anti-fall cover 41 is displaced. Specifically, the optocoupler input terminal 52 is used to emit infrared light, and the optocoupler output terminal 53 is used to receive infrared light. When the light-shielding part 411 moves relative to the optocoupler detection mechanism 5 following the displacement of the anti-fall cover 41, the light-shielding part 411 can change the light-shielding state of the optocoupler input terminal 52 and the optocoupler output terminal 53. That is, the optocoupler output terminal 53 can receive the infrared light emitted by the optocoupler input terminal 52, or the optocoupler output terminal 53 cannot receive the infrared light emitted by the optocoupler input terminal 52.

[0035] Furthermore, optical coupling detection is a non-contact detection method. The light-blocking part 411 changes the detection state only by blocking light, without mechanical contact. This helps to avoid wear between mechanical parts and greatly improves the service life and reliability of the optical coupling detection mechanism 5.

[0036] like Figures 1 to 8 The support bracket 6 shown includes a first support part 61 connected to the anti-fall top cover 41, and a second support part 62 connected to the first support part 61 and extending toward the first cleaning component 31. The corner walking wheel 2 is sleeved on the outer side wall of the second support part 62. A second elastic reset component 63 is provided between the first support part 61 and the inner side wall of the body 1. Specifically, the second elastic reset member 63 is arranged along the second direction, which is parallel to the cleaning glass surface. When the corner travel wheel 2 travels along the cleaning glass surface and touches the frame, the corner travel wheel 2 is subjected to the reverse force of the frame. The corner travel wheel 2 drives the second support part 62 to move in the opposite direction. At this time, the second elastic reset member 63 is in a squeezed state. The first support part 61 and the second support part 62 move synchronously, and the anti-fall top cover 41 is connected to the first support part 61. The anti-fall top cover 41 moves relative to the optical coupler detection mechanism 5 along the second direction, thereby realizing the optical coupler detection mechanism 5 to identify the working state of the window cleaning machine in the second direction.

[0037] Furthermore, the cross-section of the light-shielding part 411 is L-shaped, meaning that there is a light-transmitting opening on one side of the light-shielding part 411. When the machine body is placed on the clean glass surface, the anti-fall bar 43 moves relative to the light-transmitting part in the first direction. At this time, the first elastic reset member 42 is in a compressed state, and the anti-fall top cover 41 also moves in the first direction under the action of the anti-fall bar 43. The light-shielding part 411 moves in the first direction, and the optocoupler output terminal 53 can receive the infrared light emitted by the optocoupler input terminal 52 under the action of the light-transmitting opening, so that the optocoupler detection mechanism 5 outputs a low level to the main control structure of the machine body 1, and the main control structure recognizes it as a normal working state. When the corner wheel 2 moves to the window frame, the corner wheel 2 is subjected to the frame. The reverse force causes the corner wheel 2 to move the second support 62 in the opposite direction. At this time, the second elastic reset member 63 is in a compressed state. The first support 61 and the second support 62 move synchronously. The light-blocking part 411 moves along the second direction. At this time, the light-transmitting port is closed relative to the optical coupler input terminal 52 and the optical coupler output terminal 53. The optical coupler output terminal 53 cannot receive the infrared light emitted by the optical coupler input terminal 52. The optical coupler detection mechanism 5 outputs a high level to the main control structure of the body 1. At this time, the main control structure recognizes the high level triggered under normal working conditions as the corner wheel 2 touching the corner of the window. Furthermore, the main control structure recognizes the high level triggered under abnormal working conditions as the disengagement state.

[0038] like Figures 1 to 8 The anti-fall bar 43 shown has several limiting protrusions 431 on its outer side wall, and the support bracket 6 has several limiting grooves 64 that engage with the limiting protrusions 431 on its inner side wall. Furthermore, the engagement of the limiting protrusion 431 and the limiting groove 64 provides precise guidance for the movement of the anti-fall bar 43. When the anti-fall bar 43 moves linearly within the support bracket 6, the engagement of the limiting protrusion 431 and the limiting groove 64 restricts the displacement of the anti-fall bar in other directions, ensuring that the anti-fall bar 43 can only move along the path specified by the limiting groove 64. This helps to prevent the anti-fall bar 43 from swaying, tilting, or deviating during movement, ensuring the accuracy of its movement trajectory, thereby ensuring that the anti-fall mechanism 4 can work normally and stably.

[0039] Furthermore, the limiting protrusion 431 and the limiting groove 64 are designed to make the assembly of the anti-fall bar 43 and the support bracket 6 simpler and faster. During assembly, the user only needs to align the limiting protrusion 431 with the limiting groove 64 and insert it without complicated tools or adjustments, which greatly improves the assembly efficiency.

[0040] like Figures 1 to 8 The light-shielding part 411 shown is integrally formed on the anti-fall top cover 41; Furthermore, the integrally formed light-shielding part 411 and the anti-fall cover 41 can form an integral structure, avoiding loosening and separation caused by improper assembly or long-term use, so that the entire anti-fall mechanism 4 is more stable and helps to improve the reliability of the anti-fall cover 41 under complex working conditions.

[0041] Furthermore, the one-piece molding structure helps reduce assembly steps, eliminating the need for additional connectors or fixing devices, which not only improves assembly efficiency but also reduces quality problems caused by assembly errors.

[0042] Furthermore, since the light-shielding part 411 and the anti-fall cover 41 are integrally molded, their connection is tighter and they have better overall rigidity. When subjected to external impact, the integrally molded structure can more effectively resist deformation and maintain the shape and positional accuracy of the light-shielding part 411.

[0043] like Figures 1 to 8 The portion of the first cleaning component 31 that protrudes relative to the cleaning end face 23 is H. When the first cleaning component 31 is in a fully compressed state, H=0; when the body 1 is in a moving state, 0.5mm≤H≤1mm; when the body 1 is in a non-working state, 1mm≤H≤2mm. Furthermore, the first cleaning component 31 protrudes slightly from the cleaning end face 23. During the movement of the window cleaning machine, the protruding part can fit more closely to the window surface. When the cleaning end face contacts the window, the first cleaning component will be squeezed first due to the protrusion, generating a pressure on the window surface. This pressure can increase the wiping force and more effectively remove dust, stains and other impurities from the window surface.

[0044] Optionally, in some embodiments, H=0, that is, when the first cleaning component 31 is in a fully compressed state, the first cleaning component 31 is completely compressed within the mounting groove 21 and does not protrude relative to the cleaning end face 23. When the corner walking wheel 2 moves to the edge of the glass, the first cleaning component 31 is in a fully compressed state and does not protrude relative to the cleaning end face 23. This helps to ensure that the cleaning cloth does not obstruct the normal movement of the anti-fall bar 43, so that the anti-fall bar 43 can smoothly detect the window edge and the optocoupler detection mechanism 5 is triggered normally, so that the machine can receive the instruction in time to perform the retraction operation, effectively ensuring the safe use of the equipment. Furthermore, when the machine body 1 is on framed glass, the first cleaning component 31 performs its cleaning function normally; when on the edge of frameless glass, the first cleaning component 31 does not hinder the safety detection and triggering function of the anti-fall bar 43, so that the window cleaning machine has a wider range of applicability.

[0045] Optionally, in some embodiments, 0.5mm≤H≤1mm, when the window cleaning machine is working on the glass, the 0.5mm protrusion height minimizes the impact of the first cleaning component 31 on the up-and-down movement of the anti-fall bar 43. The first cleaning component 31 hardly hinders the normal movement of the anti-fall bar 43, ensuring the stability of the anti-fall bar 43 in operation. Secondly, even in the compressed state, the first cleaning component 31 can still maintain a certain pressure and friction to absorb or scrape off dust, water stains, etc., achieving a better cleaning effect.

[0046] Optionally, in some embodiments, 1mm≤H≤2mm, when the machine body 1 is in a non-working state, the first cleaning component 31 maintains a certain height relative to the cleaning end face 23, which is convenient for the user to observe and operate. When the cleaning cloth needs to be replaced, the appropriate height makes it easier to pick up and install the cleaning cloth, which is beneficial to improving the convenience of maintenance. Secondly, it ensures that the pile of the cleaning cloth is in a naturally stretched state when not in use, avoiding damage to the pile structure due to excessive compression, thereby ensuring that the cleaning cloth can maintain good cleaning performance in subsequent use.

[0047] The implementation method of Example 1 is as follows: A window cleaning machine with corner cleaning function includes a body 1, corner wheels 2 set at the corners of the body 1, a cleaning component 3 located at the bottom of the body 1, an anti-fall mechanism 4 connected to the body 1, and an optical coupler detection mechanism 5. The anti-fall mechanism 4 and the corner wheels 2 can move relative to the optical coupler detection mechanism 5 so that the optical coupler detection mechanism 5 can detect the working status of the window cleaning machine. The cleaning component 3 includes a first cleaning element 31 disposed at the bottom of the corner wheel 2, and the anti-fall mechanism 4 drives the corner wheel 2 to push the first cleaning element 31 to fit into the cleaning area.

[0048] This invention features a first cleaning component at the bottom of the corner wheels. Since these wheels are located at the four corners of the machine body, which are closest to the window frame, the first cleaning component can clean the corner areas of the window when the right angle of the machine body aligns with the right angle of the window frame. Furthermore, the anti-fall mechanism drives the corner wheels to push the first cleaning component against the cleaning area, ensuring full contact between the first cleaning component and the window surface. Applying appropriate pressure during the cleaning process allows the first cleaning component to adhere tightly to the glass, improving cleaning efficiency and effectiveness. This effectively solves the problem that existing window cleaning machines commonly use a four-corner drop bar structure, which restricts the machine's range of motion when cleaning windows with frames, preventing the machine from fully approaching the corners and leaving cleaning dead zones.

[0049] The implementation method of Example 2 is as follows: Based on Example 1, Example 2 also has the following implementation method: The corner walking wheel 2 is provided with a mounting groove 21 on the side near the cleaning area, and a Velcro 22 is provided in the mounting groove 21. The first cleaning component 31 is installed into the mounting groove 21 through the Velcro 22.

[0050] The implementation method of Example 3 is as follows: Based on Example 1, Example 3 also has the following implementation method: the first cleaning component 31 is a cleaning cloth with a velvet lining, and the corner wheel 2 includes a cleaning end face 23 located at the end, with the first cleaning component 31 protruding from the cleaning end face 23.

[0051] The implementation method of Example 4 is as follows: Based on Example 1, Example 4 also has the following implementation method: The bottom of the body 1 is provided with a mounting panel 11, and the cleaning component 3 includes a second cleaning component 32 that is detachably disposed on the side of the mounting panel 11 near the cleaning area.

[0052] The implementation method of Example 5 is as follows: Based on Example 1, Example 5 also has the following implementation method: The anti-fall mechanism 4 includes an anti-fall top cover 41 connected to the optocoupler detection mechanism 5, a first elastic reset member 42, and an anti-fall rod 43. A support bracket 6 is provided between the anti-fall top cover 41 and the anti-fall rod 43. The anti-fall rod 43 passes through the support bracket 6 and is connected to the anti-fall top cover 41. One side of the first elastic reset member 42 abuts against the anti-fall rod 43, and the other side abuts against the inner wall of the support bracket 6.

[0053] The implementation method of Example 6 is as follows: Based on Example 5, Example 6 further includes the following implementation: The anti-drop top cover 41 includes a light-shielding part 411 extending toward the optical coupler detection mechanism 5. The optical coupler detection mechanism 5 includes an optical coupler support plate 51, an optical coupler input end 52 and an optical coupler output end 53 disposed opposite to each other on the optical coupler support plate 51. The light-shielding part 411 is located between the optical coupler input end 52 and the optical coupler output end 53 and changes its light-shielding state on the optical coupler input end 52 and the optical coupler output end 53 as the anti-drop top cover 41 is displaced.

[0054] The implementation method of Example 7 is as follows: Based on Example 6, Example 7 also has the following implementation method: The support bracket 6 includes a first support part 61 connected to the anti-fall top cover 41 and a second support part 62 connected to the first support part 61 and extending toward the first cleaning member 31. The corner walking wheel 2 is sleeved on the outer side wall of the second support part 62. A second elastic reset member 63 is provided between the first support part 61 and the inner side wall of the body 1.
