Description

Technical Field

[0001] The utility model relates to a cleaning robot, in particular to a single suction port assembly capable of removing garbage such as cloth scraps and wool yarns. Background Art

[0002] Existing cleaning robots generally include two functions: sweeping and mopping. The sweeping function mainly relies on a rolling brush assembly. The rolling brush assembly sweeps dust to the middle position of the rolling brush through a rolling brush with a corrugated shape, and then uses negative pressure to suck the dust into the dust box of the cleaning robot. The above-mentioned cleaning robot can usually meet general use environments. However, for some special use environments, such as in clothing production workshops, barbershops and other use environments, since there are fine and long strip debris in these use environments, the cleaning effect of the above-mentioned cleaning robot is not good. Taking a clothing production workshop as an example, there are often a lot of cloth scraps and wool yarns on the workshop floor. These cloth scraps and wool yarns are easily wound around the rolling brush and cannot be sucked into the dust box. In severe cases, the rolling brush may even be stuck and unable to rotate, thus affecting the cleaning function.

[0003] Based on the above deficiencies, therefore, there is a need to develop a more suitable cleaning robot specifically for clothing factories and similar use environments. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a single suction port assembly suitable for clothing factories, capable of removing garbage such as cloth scraps and wool yarns, and having a good cleaning effect.

The side brush assembly 5 can sweep the garbage on both sides of the robot main body 2 towards the middle to facilitate the single suction port assembly 1 to collect the garbage.

[0029] Please refer to Figures 7 to 10, the single suction port assembly 1 includes a housing 11, a scraping strip 12, a fixed cover 13 and a suction port 14. The scraping strip 12 is arranged on the bottom surface of the housing 11 and can elastically abut against the ground during operation to achieve scraping of the ground. The fixed cover 13 is connected to the bottom surface of the housing 11 and clamps the scraping strip 12 with the housing 11. The horizontal projection of the scraping strip 12 is arc-shaped; the suction port 14 is arranged on the housing 11 and penetrates the surface and bottom surface of the housing 11. The suction port 14 is located in the middle of the concave side of the arc. The single suction port assembly 1 further includes a base body 15, and the housing 11 is detachably arranged on the base body 15. The base body 15 is arranged on the bottom surface of the robot main body 2.

[0030] Please refer to again Figure 9, the single suction port assembly 1 further includes a locking mechanism 16, and the locking mechanism 16 is disposed on the housing 11 to position the housing 11. This can enable the housing 11 to be quickly fixed, improving the convenience of assembly. The locking mechanism 16 includes a latch 161 and a reset member 162. A locking hole 153 is provided at a position corresponding to the latch 161 on the base 15. One end of the housing 11 is provided with a sliding groove 11a. The latch 161 is slidably disposed in the sliding groove 11a. The reset member 162 is disposed between the housing 11 and the latch 161 to make the latch 161 protrude toward the upper surface of the housing 11. When the housing 11 is mounted on the base 15, the front end of the latch 161 is engaged with the locking hole 153, so that the housing 11 and the base 15 are locked to each other.

The central axis direction of the pivot shaft is perpendicular to the traveling direction of the cleaning robot 100. The guide wheels 17 can support the housing 11, making the cleaning robot 100 walk more stably and smoothly.

[0033] Combining the above and in conjunction with the above drawings, the working principle of the cleaning robot 100 of the present invention will be described in detail as follows:

[0034] When floor sweeping is needed, start the robot main body 2. The robot main body 2 walks forward. At the same time, start the side brush assembly 5 to make the wool or cloth scraps on both sides move closer to the middle. And under the scraping of the scraping strip 12, the wool and cloth scraps gather towards the middle of the concave surface of the scraping strip 12. At this time, start the blower 3 to generate negative pressure at the inlet of the blower 3, so as to generate negative pressure at the suction port 14 and its vicinity, and thus the wool and cloth scraps located in the middle of the concave surface of the scraping strip 12 are sucked into the dust box 4. After being filtered by the dust box 4, the purified gas is discharged from the air outlet of the cleaning robot 100, which will not affect the surrounding environment, while the wool and cloth scraps remain in the dust box 4. When it is necessary to clean the single suction port assembly 1, press the pressing position 161a so that the lock catch 161 disengages from the locking hole 153. Thus, the lock catch 161 unlocks the housing 11. After that, pull out the housing 11 from the seat body 15, and finally, clean the housing 11 and the components connected to the housing 11. After the cleaning is completed, just insert the housing 11 into the seat body 15 and lock it, and the cleaning robot 100 can continue the cleaning work.

[0035] Compared with the prior art, in the present utility model, a scraping strip 12 is arranged on the housing 11, and the horizontal projection of the scraping strip 12 is arc-shaped. The fixed cover 13 and the housing 11 are used to clamp the scraping strip 12 together, so that the scraping strip 12 can directly scrape and sweep the cloth scraps, wool and other garbage on the ground, so that these garbage can be quickly concentrated in the middle of the concave surface side of the scraping strip 12. Then, the cloth scraps, wool and other garbage are directly sucked into the dust box 4 of the cleaning robot 100 through the suction port 14 arranged in the middle of the concave surface side of the scraping strip 12. This cleaning method can avoid the problem that the cloth scraps, wool and other garbage are wound around the roller brush and thus cannot be sucked away by negative pressure, and at the same time, it can also prevent the roller brush from being stuck. Therefore, the single suction port assembly 1 of the present utility model can quickly remove the cloth scraps, wool and other garbage, and is suitable for clothing factories and similar use environments, and the cleaning effect is extremely good.

[0036] The robot main body 2 involved in the cleaning robot 100 of the present utility model further includes a traveling mechanism 22 that can drive the cleaning robot to travel and a control circuit board that controls the start and stop of each electrical component. These structures are well known to those of ordinary skill in the art and will not be described in detail here.

[0037] The above-disclosed are only the preferred examples of the present utility model. Of course, the scope of rights of the present utility model cannot be limited by this. Therefore, the equivalent changes made according to the scope of the patent application of the present utility model still fall within the scope covered by the present utility model.
