[0002] Sweepers and floor scrubbers have been widely used by sanitation, cleaning, property management and corporate units, and the baffle is one of the indispensable accessories for each device. The baffle structure refers to the roller brush baffle structure of the sweeping robot. The roller brush baffle structure is generally installed at the bottom of the sweeper, specifically around the roller brush. The roller brush baffle mainly plays the role of fixing the roller brush, preventing dust from spreading and combing garbage. Since the baffle needs to be adjusted and replaced frequently, the rapid adjustment and disassembly of the baffle becomes a condition that must be met by the vehicle to facilitate daily cleaning of the baffle.

[0003] The defects of the barrier structure in the prior art are:

[0004] 1. Patent document JP3231715U discloses a floor brush assembly, which cannot quickly adjust the height of the cover plate according to usage requirements, has a limited range of use, reduces cleaning efficiency, and cannot guarantee the cleaning area and cleaning quality of the floor brush.

[0005] 2. Patent document CN216876262U discloses a roller brush cover assembly for a sweeping machine that is easy to disassemble. The roller brush cover assembly cannot ensure the stability of its connection with the sweeping machine through the auxiliary spring and the mounting block limiter, and is not easy to disassemble and assemble, which reduces the enthusiasm of users for maintenance. During use, the cover assembly is prone to deviation relative to the sweeping machine body, which has an adverse effect on the use of the roller brush.

[0006] 3. Patent document CN217185916U discloses a roller brush structure that can be quickly disassembled and assembled. During use, the roller brush structure cannot detect the working status of the roller brush, cannot clean foreign objects wrapped around the outside of the roller brush, and may easily cause damage to the roller brush, and cannot guarantee the cleaning effect of the sweeper.

[0007] 4. Patent document CN216876202U discloses a roller brush cover structure for an intelligent sweeping machine. The roller brush cover structure is easily worn during use, resulting in incomplete cleaning of garbage and a decrease in cleaning ability. It cannot cushion the impact force of the bottom collision during the cleaning process, shortening the service life of the cover and failing to ensure the good performance of the intelligent sweeping machine.

The barrier driving module is electrically connected to the electromagnet and the micro hand lever, and the signal reading module receives the output signals of the squeeze contact sensor and the speed measuring instrument, and the signal reading module is electrically connected to a speed comparison unit.

[0018] Preferably, the steps for using the barrier structure are as follows:

[0019] S1. First, bolts are passed through the bolt connection holes and assembly holes to ensure a secure installation between the guard frame and the guard mounting bracket. After the guard frame and the guard mounting bracket are assembled, the fixed arc plate is fitted with the connection at the bottom of the sweeper. The equipment connection bolts are passed through the inner side of the threaded connection holes and matched with the threaded connection holes of the sweeper to achieve preliminary fixation. The electromagnet and the iron sheet at the bottom of the sweeper are magnetically attracted to each other.

[0020] S2. Press the docking convex frame to press the extrusion spring and locate it inside the extrusion groove, pull the height adjustment seat, and the height adjustment seat drives the sliding block to slide inside the retaining skin mounting frame to adjust the height of the retaining skin frame. Engage the sweeping roller brush slot with the sweeping machine roller brush. After installation, the docking convex frame pops outward under the elastic force of the extrusion spring and engages with the inner side of the docking limit hole to achieve limit fixation of the height adjustment seat in use position, and the speed measuring instrument cooperates with the roller brush shaft;

[0021] S3. The bottom end of the sweeper's roller brush contacts the ground through the roller brush working groove. When the sweeper is running, the roller brush shaft is driven. The roller brush continuously rotates to sweep the ground garbage and collect it into the sweeper's garbage bin. The speed measuring instrument continuously monitors the speed of the roller brush shaft.

[0022] S4. When the sweeper is subjected to friction and impact during operation, the bottom contact plate is compressed to squeeze the telescopic spring. The damper and the telescopic spring cooperate to buffer the impact force transmitted from the bottom. When cleaning a lot of garbage, the bottom contact plate is compressed to a large extent and contacts the squeeze contact sensor. The squeeze contact sensor transmits a signal to the sweeper control system to alert the user.

[0023] Preferably, the step S3 further includes the following steps:

[0024] S31. When the speed measuring instrument detects abnormal changes in the speed of the roller brush shaft, it indicates that hair and debris are entangled in the roller brush. The sweeper control system drives the micro hand lever to work. The micro hand lever pushes the support seat to make the scraping table higher than the long storage tank. During the rotation of the roller brush, the scraping table scrapes off the impurities attached to the outer surface of the roller brush. The scraped impurities fall to the top of the expansion inclined plate in the long storage tank under the blocking effect of the anti-fall baffle.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The present invention provides a lifting adjustment component on the inner side of the barrier mounting frame. When the barrier structure is assembled with the sweeping machine roller brush, the docking convex frame is pressed to press the extrusion spring and be located inside the extrusion groove, and the height adjustment seat is pulled. The height adjustment seat drives the sliding block to slide inside the barrier mounting frame, and the height of the barrier frame is adjusted to engage the sweeping machine roller brush slot with the sweeping machine roller brush. After installation in place, the docking convex frame pops outward under the elastic force of the extrusion spring and engages inside the docking limit hole to achieve limited fixation of the use position of the height adjustment seat. The height of the barrier frame can be quickly adjusted according to the use requirements of the sweeping machine to meet the use requirements of sweeping machine roller brushes of different specifications, improve the cleaning efficiency while ensuring the cleaning area and cleaning quality.

[0027] 2. The present invention installs a fixed arc plate on the outer top of the skin barrier mounting frame. When the skin barrier structure is installed, bolts pass through the bolt connection holes and the assembly holes to achieve a stable installation between the skin barrier frame and the skin barrier mounting frame. After the skin barrier frame and the skin barrier mounting frame are assembled, the fixed arc plate is fitted with the bottom connection of the sweeper. The equipment connection bolts pass through the inner side of the threaded connection hole and cooperate with the thread of the sweeper connection hole to achieve preliminary fixation. The mutual magnetic adsorption between the electromagnet and the iron sheet at the bottom of the sweeper further ensures the stability of the connection between the two, facilitates disassembly and assembly, and improves the enthusiasm of users for maintenance. The double fixation prevents the skin barrier structure from being offset relative to the sweeper body during use, which has an adverse effect on the use of the roller brush.

[0028] 3. The present invention is provided with a load-reducing cleaning component on the inner side of the baffle frame. The bottom end of the sweeper's roller brush contacts the ground through the roller brush working groove. The sweeper drives the roller brush shaft when it is running. The dust-blocking thin angle frame can effectively block the space under the roller brush to prevent dust from spreading. The speed measuring instrument continuously monitors the speed of the roller brush shaft. When the speed measuring instrument detects abnormal changes in the speed of the roller brush shaft, it indicates that hair and debris are entangled in the roller brush. The micro hand lever pushes the support seat to make the height of the scraping table higher than the long storage tank. During the rotation of the roller brush, the scraping table scrapes off impurities attached to the outer surface of the roller brush. The scraped impurities fall to the top of the expansion inclined plate in the long storage tank under the blocking effect of the anti-fall baffle. The automatic cleaning of foreign matter entangled on the surface of the roller brush prevents the roller brush from being damaged by foreign matter, thereby improving the cleaning effect of the sweeper.

[0029] 4. The present invention provides a wear-resistant protection component at the bottom of the barrier frame. When the sweeper is subjected to friction and impact during operation, the bottom touch plate is compressed to squeeze the telescopic spring. The damper and the telescopic spring cooperate to buffer the collision impact force transmitted from the bottom, thereby protecting the roller brush of the sweeper from collision and reducing the degree of damage to the roller brush when the sweeper is working. The bottom touch plate and the wear-resistant pad prevent the sweeper from wearing out the bottom of the barrier frame due to long-term use, thereby extending the service life of the barrier structure. When cleaning a large amount of garbage, the bottom touch plate is subjected to a large degree of pressure and contacts the extrusion contact sensor. The extrusion contact sensor transmits the signal to the sweeper control system to warn the user, thereby ensuring the good performance of the cleaning equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] See also Figure 1 and Figure 8 , a quick-disassembly and quick-assembly cleaning equipment retaining leather structure;

[0058] Including a speed measuring instrument 28, a long storage tank 6 and a scraping table 33, the inner side of the leather frame 1 is provided with a load-reducing cleaning component, the load-reducing cleaning component includes a long storage tank 6, a speed measuring instrument 28, a miniature hand lever 30, a support seat 32 and a scraping table 33, the long storage tank 6 is symmetrically opened on the bottom wall of the leather frame 1, the speed measuring instrument 28 is installed on the inner wall of the leather frame 1, and the speed measuring instrument 28 cooperates with the roller brush shaft of the sweeper, and the miniature hand lever 30 is installed on the long storage tank 6. On the bottom wall, the support seat 32 is installed at the telescopic end of the miniature hand lever 30, the scraping platform 33 is installed on the top of the support seat 32, and the anti-fall baffle 29 is symmetrically installed on the bottom wall of the baffle frame 1, and the anti-fall baffle 29 cooperates with the long storage tank 6. An auxiliary groove 31 is opened on the inner wall of the long storage tank 6, and the outer end of the support seat 32 slides on the inner side of the auxiliary groove 31. An expansion ramp 34 is installed on the other side of the support seat 32, and a rubber pad 35 is installed on the outer end of the expansion ramp 34;

[0059] When the sweeper is running, the roller brush shaft is driven, and the roller brush rotates continuously to sweep the garbage on the ground and collect it into the garbage bin of the sweeper. The speed measuring instrument 28 continuously monitors the speed of the roller brush shaft. When the speed measuring instrument 28 detects an abnormal change in the speed of the roller brush shaft, it indicates that hair and debris are entangled in the roller brush. The accumulation of garbage will slow down the speed of the roller brush shaft. The sweeper control system drives the micro hand lever 30 to work, and the micro hand lever 30 pushes the support seat 32 to make the scraping gear platform 33 higher than the long storage tank 6. The support seat 32 slides inside the auxiliary groove 31 to ensure the stability of the moving process. During the rotation of the roller brush, the scraping gear platform 33 scrapes off impurities attached to the outer surface of the roller brush, and the scraped impurities fall to the top of the expansion inclined plate 34 in the long storage tank 6 under the blocking effect of the anti-fall baffle 29;

[0060] The expansion ramp 34 increases the storage space while protecting the miniature hand lever 30 to prevent the water vapor in the garbage disposal from adversely affecting its performance. The rubber pad 35 blocks the gap between the expansion ramp 34 and the inner wall of the long storage tank 6 without causing wear on the inner wall of the long storage tank 6. The staff only needs to clean the inside of the long storage tank 6 regularly. The scraping table 33 is not always in working condition because when there is less garbage attached to the outside of the roller brush, the contact between the scraping table 33 and the roller brush will affect its rotation speed, resulting in poor cleaning effect.

[0061] The steps for using the skin barrier structure are as follows:

[0062] S1. First, bolts are passed through the bolt connection holes 23 and the assembly holes 10 to achieve a stable installation between the barrier frame 1 and the barrier mounting bracket 2. After the barrier frame 1 and the barrier mounting bracket 2 are assembled, the fixed arc plate 3 is fitted with the connection at the bottom of the sweeper. The equipment connection bolts 16 are passed through the inner side of the threaded connection holes 14 and matched with the threaded connection holes of the sweeper to achieve preliminary fixation. The electromagnet 17 is magnetically attracted to the iron sheet at the bottom of the sweeper.

[0063] S2. Press the docking cam 20 to press the extrusion spring 21 and locate it inside the extrusion groove 19, pull the height adjustment seat 4, and the height adjustment seat 4 drives the sliding block 18 to slide inside the retaining wall mounting frame 2, adjust the height of the retaining wall frame 1, and engage the sweeping roller brush slot 7 with the sweeping machine roller brush. After installation, the docking cam 20 pops outward under the elastic force of the extrusion spring 21 and engages with the inner side of the docking limit hole 12 to achieve the limit fixation of the use position of the height adjustment seat 4, and the speed measuring instrument 28 cooperates with the roller brush shaft;

[0064] S3, the bottom end of the sweeper's roller brush contacts the ground through the roller brush working groove 8, and the roller brush shaft is driven when the sweeper is running. The roller brush continuously rotates to sweep the ground garbage and collect it into the sweeper's garbage bin. The speed measuring instrument 28 continuously monitors the speed of the roller brush shaft;

[0065] S4. When the sweeper is subjected to friction and impact during operation, the bottom contact plate 25 is compressed to squeeze the telescopic spring 24. The damper 5 and the telescopic spring 24 cooperate to buffer the impact force transmitted from the bottom. When cleaning a large amount of garbage, the bottom contact plate 25 is compressed to a large extent and contacts the squeeze contact sensor 27. The squeeze contact sensor 27 transmits a signal to the sweeper control system to warn the user.

[0066] In step S3, the following steps are also included:

[0067] S31. When the speed measuring instrument 28 detects abnormal changes in the speed of the roller brush shaft, it indicates that hair and debris are entangled in the roller brush. The sweeper control system drives the micro hand lever 30 to work. The micro hand lever 30 pushes the support seat 32 to make the scraping table 33 higher than the long storage tank 6.

[0070] The bottom end of the sweeper's roller brush contacts the ground through the roller brush working groove 8. When the sweeper is running, the roller brush shaft is driven, and the roller brush rotates continuously to sweep the garbage on the ground and collect it into the garbage bin of the sweeper. The speed measuring instrument 28 continuously monitors the speed of the roller brush shaft. When the speed measuring instrument 28 detects an abnormal change in the speed of the roller brush shaft, it indicates that hair and debris are entangled in the roller brush. The sweeper control system drives the micro hand lever 30 to work, and the micro hand lever 30 pushes the support seat 32 to make the scraping gear platform 33 higher than the long storage tank 6. During the rotation of the roller brush, the scraping gear platform 33 scrapes off impurities attached to the outer surface of the roller brush. The scraped impurities fall to the top of the expansion inclined plate 34 in the long storage tank 6 under the blocking effect of the anti-fall baffle 29;

[0071] When the sweeper is subjected to friction and impact during operation, the bottom contact plate 25 is compressed to squeeze the telescopic spring 24. The damper 5 and the telescopic spring 24 cooperate to buffer the collision impact force transmitted from the bottom. When cleaning a large amount of garbage, the bottom contact plate 25 is under great pressure and contacts the squeeze contact sensor 27. The squeeze contact sensor 27 transmits a signal to the sweeper control system to alert the user.
