Description
Technical Field
[0001] The invention relates to the field of sweeping machines, in particular to a sweeping machine with multiple suction ports. Background Art
[0002] With the advancement of technology and the improvement of living standards, sweepers, as an efficient floor cleaning tool, play an increasingly important role in people's daily lives. They can not only reduce the burden of manual cleaning, but also improve cleaning efficiency. They are widely used in homes, offices, shopping malls and other places. However, despite the continuous optimization of the design and function of sweepers, there are still some obvious problems in the design of the suction port, especially the limited number of suction ports, usually only one, which greatly limits its cleaning effect. Summary of the invention
[0003] The purpose of the present invention is to solve the above-mentioned technical problems and to provide a sweeping machine with multiple suction ports. The present application improves the cleaning effect of the sweeping machine by increasing the number of suction ports.
[0004] A sweeping machine with multiple suction ports, including a chassis and a first scraper of the sweeping machine, the chassis having a first suction port and a second suction port, the first scraper comprising a straight portion and an oblique portion, the straight portion being arranged at the rear side of the first suction port, the oblique portion extending obliquely relative to the straight portion to the side of the first suction port, a notch being arranged between the straight portion and the oblique portion, the sweeping machine having a traveling direction during cleaning, in the traveling direction, the first suction port and the first scraper being arranged in front of the second suction port so that the notch is opposite to the second suction port.
[0005] According to the sweeping machine with multiple suction ports of the present application, the sweeping machine can be used to sweep and wipe the ground. Therefore, a general sweeping machine is equipped with a scraper to gather water stains on the ground. In order to enable the water stains to gather on the suction port of the sweeping machine, the scraper will be semi-enclosed and arranged on the rear side of the suction port, so that the water stains on the ground can gather at the suction port and be sucked into and stored by the sweeping machine. Since the shape of the scraper is not a straight strip but a semi-enclosed shape, if the scraper is set to be complete, it will easily cause abnormal noise when hanging water. Therefore, it is necessary to set the scraper to multiple sections, forming gaps between the multiple sections, so as to avoid abnormal noise when scraping water. This results in that if there are too many water stains, a water line will be formed on the rear side of the sweeping machine's travel direction. The present application improves the suction port and newly sets a second suction port on the basis of the first suction port. The water line left by the first suction port is sucked through the second suction port, thereby avoiding leaving a water line on the rear side of the sweeping machine.
[0006] Furthermore, the second suction port can be closed, opened, and the opening size can be adjusted. When no water line is generated, the second suction port can be closed to avoid affecting the suction force of the first suction port, and the opening size of the second suction port can be adjusted according to the amount of water on the water line to adjust the suction force.
[0007] Furthermore, it also includes a dust collection box, which is provided with a first inlet and a second inlet, the first inlet is connected to the first suction port, the second inlet is connected to the second suction port, and the dust collection box is provided with an openable cover at the second inlet, and the cover can be opened and closed so that the second suction port can be closed, opened and the opening size can be adjusted.
[0008] Furthermore, it also includes a driving device, which is connected to the cover plate through a transmission system, and the driving device drives the cover plate to translate or flip.
[0009] Furthermore, the first scraper is provided with a detection device at the notch, and the detection device is used to detect whether there is water leakage from the notch. When water leakage from the notch occurs, the second suction port is controlled to open and the size of the opening.
[0010] Furthermore, the detection device includes detection electrodes arranged on two side walls of the gap by the first scraper. When water stains leak from the gap, the detection electrodes form a conductive circuit through the water stains, thereby detecting whether water stains leak from the gap.
[0011] Furthermore, it also includes a dust suction fan, the dust suction box has an outlet, the dust suction fan is connected to the outlet, and the dust suction box is provided with a filtering device between the first inlet and the second inlet and the outlet.
[0012] Furthermore, the filtering device is a filter net, and the first inlet and the second inlet share a filter net.

In the moving direction, the first suction port 11 and the first scraper 2 are arranged in front of the second suction port 12, so that the gap 23 is opposite to the second suction port 12. The position of the second suction port 12 can make the water line leaking from the gap 23 when there is too much water stains can be sucked into the sweeping machine by the second suction port 12, avoiding leaving a water line behind the moving direction of the sweeping machine.
[0022] The second suction port 12 can be closed, opened and the size of the opening can be adjusted. The second suction port 12 can be closed when there is no water line to avoid affecting the sewage suction effect of the first suction port 11. When the water line appears, the second suction port 12 can be opened, so that the water line leaked from the first suction port 11 can be sucked into the sweeper through the second suction port 12 at the rear.
