[0031] The present invention mainly proposes a floor cleaning robot that is equipped with a dust jet structure 200, which can clean dust in narrow spaces such as gaps in a floor, and is advantageous in improving the cleaning ability of the floor cleaning robot.

[0032] The following mainly describes the specific configuration of the floor cleaning robot.

[0033] Referring to FIG. 1 to FIG. 10, in an embodiment of the present invention, the floor cleaning robot includes: A chassis 100; The dust jet generation structure 200 is attached to the chassis 100 and has an air intake 220, an exhaust 230, and a jet passage 210 communicating between the air intake 220 and the exhaust 230, the air intake 220 is for introducing air into the jet passage 210, and the exhaust 230 is located in front of a floor brush suction port 110 of the floor cleaning robot. The floor brush suction port 110 is opened at the bottom of the chassis 100, and a roller brush is provided in the floor brush suction port 110.

[0034] Specifically, in this embodiment, the jet dust-generating structure 200 may have various shapes, such as a plate shape, a block shape, or a strip shape, but is not particularly limited here, and may have a jet passage 210 capable of jetting to obtain a dust-raising effect. The jet dust-generating structure 200 may be attached to the chassis 100 in various ways, such as snap connection, screw connection, adhesive connection, and plug connection. Of course, in some embodiments, a slot may be provided in the chassis 100, and the jet dust-generating structure 200 may be snapped into the slot. In this embodiment, the jet dust-generating structure 200 and the chassis 100 are formed as one piece. The chassis 100 may have various shapes, such as a polygonal shape, an elliptical shape, or a circular shape, but the chassis 100 is circular so that the floor cleaning robot can enter a narrower space when the volume is the same.

[0035] The relationship between the jet dust generation structure 200 and the chassis 100 may be various, for example, an attachment port may be opened in the chassis 100 and the jet dust generation structure may be attached to this attachment port, or the jet dust generation structure may be directly attached to the chassis 100 in which a via hole communicating with the jet passage 210 is formed to allow the airflow to pass through. It is only necessary to ensure that the airflow is sent from the exhaust port 230 of the jet passage 210 to the floor in front of the floor brush suction port 110.

[0036] A specific example of the jet dust generating structure 200 including a jet sheet in which a plurality of the jet passages 210 arranged along the longitudinal direction of the floor brush suction port 110 are opened will be described below. In this embodiment, the jet dust generating structure 200 is a jet sheet, and the jet passages 210 penetrate both opposing plate surfaces of the jet sheet. An attachment port is opened in the chassis 100, and the jet sheet is attached to the attachment port so that the intake port 220 of the jet passages 210 communicates with the top of the chassis 100 and the exhaust port 230 communicates with the bottom of the chassis 100. By providing a plurality of jet passages 210, all dust in front of the floor brush suction port 110 can be reliably lifted, which is advantageous for improving the cleaning effect of the floor cleaning robot. The intake ports 220 may supply air individually or collectively, but when supplying air collectively, an intake cavity is required. In this case, the jet structure further includes an enclosure 240 that is surrounded by the jet sheet to form an intake cavity, and the intake port 220 is located in the intake cavity. The enclosure 240 is provided in an elongated shape, and its cross section may be L-shaped or notched. If it is arranged in an L-shape, a barrier needs to be provided on the chassis 100, and the structure formed by the enclosure 240 and the barrier is covered on the jet sheet, and if it is arranged in a notch, the enclosure 240 is covered on the jet sheet to form the intake cavity. Of course, in some embodiments, the enclosure 240 may be provided so as to be integrally molded with the chassis 100, or may be provided so as to be integrally molded with the jet sheet. In some embodiments, the jet sheet and the chassis 100 are provided so as to be integrally molded in order to simplify the manufacturing and installation process of the jet sheet.

[0037] In this embodiment, a jet dust-generating structure 200 is provided on the chassis 100, in which a jet passage 210 penetrates the top and bottom of the chassis 100, and an airflow enters the jet passage 210 from an air intake port 220, passes through the jet passage 210, and is ejected from an exhaust port 230, lifting up dust in front of the floor brush suction port 110, and the lifted dust is sucked into the floor brush suction port 110.When the airflow is ejected, it not only lifts up dust on a flat surface, but also lifts up dust in gaps.By lifting up dust that cannot be directly sucked into the floor brush suction port 110, the floor brush suction port 110 can suck in dust in narrow spaces such as gaps, which is advantageous for improving the dust suction efficiency of the floor brush suction port 110 and improving the cleaning ability of the floor cleaning robot.

[0038] In some embodiments, the jet passage 210 can achieve a better dusting effect.

[0039] The exhaust port 230 is provided facing the direction of the floor brush suction port 110. By facing the exhaust port 230 toward the floor brush suction port 110, the airflow discharged from the jet passage 210 causes dust to drop toward the floor brush suction port 110. This makes it easier for the floor brush suction port 110 to absorb dust. The jet passage 210 extends from the top of the front side of the chassis 100 toward the floor brush suction port 110 at an incline. That is, the jet passage 210 extends rearward, and the jet passage 210 discharges the airflow rearward. By providing the intake port 220 at the top of the chassis 100, the intake of the jet passage 210 does not affect the jet of the exhaust port 230, and the inclination of the jet passage 210 can be kept top-down, which is advantageous for the transmission of the airflow.

[0040] In order to further ensure the jet effect, the angle α of the jet passage 210 with respect to the vertical direction is 20° to 70°. The angle between the jet passage 210 and the vertical direction is the deflection angle of the jet passage 210 toward the floor brush suction port 110. If the angle α is too small, the jetted airflow will be jetted to the front side of the floor brush suction port 110, which is unfavorable for directly entering the floor brush suction port 110, and if the angle α is too large, the jetted distance will be too long and there is a possibility that the air will fall to the rear side of the floor brush suction port 110, which is also unfavorable for directly being sucked into the floor brush suction port 110.

[0041] The inner wall surface of the jet passage 210 may be flat or curved, but in some embodiments, it may have both flat and curved surfaces. In the following, we will first provide an example of a flat surface, and then provide an example of a surface having both flat and curved surfaces.

[0042] The jet passage 210 extends in a straight line, and the inner wall surface of the jet passage 210 is formed of a flat surface. In this embodiment, the jet passage 210 is a straight passage, and the resistance of the airflow in the jet passage 210 is small, so that the airflow can be easily and quickly ejected from the exhaust port 230. At the same time, the straight jet passage 210 is easy to process, and it is convenient to simplify the processing. Of course, in some special cases, the jet passage 210 requires a large angle change, and in this case, it is necessary to guide the airflow with a curved surface so that the airflow can smoothly transition during the process of deflecting the angle.

[0043] In some embodiments, in order to provide a large rotation angle for the jet passage 210 within the available space, a curved section is provided in the vicinity of the exhaust port 230, and the jet passage 210 is composed of an intake section provided in the vicinity of the intake port 220 and a jet section provided in the vicinity of the exhaust port 230, the intake section extending in a straight line and the jet section extending in a curved line. In this embodiment, the airflow first passes through the straight intake section, and the direction of the airflow needs to be adjusted before the airflow is ejected from the exhaust port 230, and the provision of the jet section allows the jet angle of the ejected airflow to provide an optimal jetting effect.

[0044] In order to further improve the dust-generating effect, the cross-sectional area of ​​the jet passage 210 gradually decreases from the intake port 220 to the exhaust port 230. By gradually decreasing the cross-sectional area of ​​the jet passage 210, the air pressure of the airflow in the jet passage 210 gradually increases, and the flow rate of the airflow at the exhaust port 230 increases, which is advantageous for greatly improving the dust-generating effect. In order to further improve the accuracy of adjusting the pressure and flow rate in the jet passage 210, the ratio S1 / S2 of the area S1 of the exhaust port 230 to the area S2 of the intake port 220 is 0.2 or more and less than 1. Within a certain range, the ratio of the area of ​​the exhaust port 230 to the area of ​​the intake port 220 is inversely correlated with the increase in pressure and flow rate, but the ratio of the area of ​​the exhaust port 230 to the area of ​​the intake port 220 should not be too large. If it is equal to 1, the effect of increasing pressure and speed cannot be obtained. If it is less than 0.2, the area difference between the exhaust port 230 and the intake port 220 will be large, which will affect the normal flow of the airflow and be detrimental to the injection of the airflow.

[0045] In order to obtain a better jetting effect, the length L of the exhaust port 230 is 3 to 20 mm, and / or the width D of the exhaust port 230 is 0.5 to 3 mm. The length of the exhaust port 230 should not be too long or too short. If it is too long, the airflow flowing out in the longitudinal direction of the exhaust port 230 becomes uneven, and turbulence is likely to occur along the longitudinal direction, which is disadvantageous to accurate jetting of the airflow. If the length of the exhaust port 230 is too short, the jetting length is insufficient and the effect is not good. Similarly, the width of the exhaust port 230 should not be too large or too small. If it is too large, the airflow flowing out in the width direction of the exhaust port 230 becomes uneven, and turbulence is likely to occur along the width direction, which is disadvantageous to accurate jetting of the airflow. If the width of the exhaust port 230 is too short, the jetting width is insufficient and the effect is not good.

[0046] In order to further improve the dust-removal effect of the jet passage 210, the distance K between the exhaust port 230 and the floor brush suction port 110 is greater than 0 and less than or equal to 20 mm. The distance between the exhaust port 230 and the floor brush suction port 110 is very important, because after the airflow is injected into the ground (gap), it bounces back and is sprayed back to the floor brush suction port 110. If the distance between the exhaust port 230 and the floor brush suction port 110 is too long, it is difficult for the airflow to be injected into the floor brush suction port 110 accurately and quickly, resulting in poor dust-removal effect.

[0047] In some embodiments, in order to improve the efficiency of intake, an intake cavity having an inlet 260 for the airflow is formed in the chassis 100, and the intake port 220 is connected to the intake cavity. When the number of intake ports 220 is multiple, the multiple intake ports 220 can be connected to the intake port at the same time to supply air from the multiple intake ports 220 at the same time. In addition, by providing the intake cavity, the position of the intake port 220 is more flexible and can be easily accommodated to the floor brush inlet 110. The intake cavity extends along the longitudinal direction of the floor brush inlet 110, so that the intake port 220 and the exhaust port 230 can be accommodated to the floor brush inlet 110, while the length of the jet passage 210 can be shortened to shorten the path of the airflow.

[0048] In order to simplify the overall machine structure and supply air by utilizing the existing structure as rationally as possible, the floor cleaning robot further includes a dust suction motor 900 whose exhaust port is connected to the air intake port 220 and / or the inlet port 260 of the air intake cavity of the chassis 100. The dust suction motor 900 is connected to the dust cup 700 and the floor brush suction port 110, and is for forming a negative pressure at the floor brush suction port 110 to suck dust. In this embodiment, the airflow drawn out from the dust cup 700 is also conveyed to the jet passage 210, forming an airflow circulation. In the circulation path, the floor brush suction port 110 sucks in the airflow by the action of the negative pressure, and the airflow flows from the floor brush suction port 110 to the dust cup 700, and then enters the jet passage 210 through the dust suction motor 900, and the airflow ejected from the jet passage 210 is sucked into the floor brush suction port 110. By stacking the dust suction motors 900 in this manner, the utilization rate of the dust suction motors 900 can be significantly improved.

[0049] The air outlet of the dust suction motor 900 and the air inlet 220 and / or the air inlet 260 of the air intake cavity of the chassis 100 may be connected by a duct or directly, and may be connected by a hose 270. Specifically, the air outlet and the air inlet 220 and / or the air inlet 260 are connected by a hose 270, and the floor cleaning robot includes a mounting tube 800 formed for mounting a roller brush, and a slot is provided on the side of the mounting tube 800 facing away from the roller brush to which a part of the hose 207 is engaged. In this embodiment, the air exhaust port of the dust suction motor 900 and the air intake port 220 of the jet passage 210 are connected via a hose 270. Since the hose 270 has low rigidity, there is a possibility that it may rattle during operation. However, by providing a slot and fixing the hose 270, rattling of the hose 270 can be prevented and the stability of the operation of the hose 270 can be improved.

[0050] In some embodiments, the air outlet and the air inlet 220 and / or the air inlet 260 are connected by a hose 270, and the floor cleaning robot includes a mounting tube 800 for mounting a roll brush, and a mounting pole 760 to which a circuit board of the floor cleaning robot is attached is provided on the side of the mounting tube 800 facing away from the roller brush, and the hose 270 passes through a limiting gap surrounded by the circuit board, the mounting pole 760, and the mounting tube 800. There are two mounting poles 760, which support both ends of the circuit board, respectively, and a limiting gap is formed by being surrounded by the two mounting poles 760, the top of the mounting tube 800, and the circuit board, so that the hose 270 is less likely to rattle after passing through, and the stability of the operation of the hose 270 is improved.

[0051] In some embodiments, in order to be able to control the strength of the jet and the duration of the jet at the same position according to the current degree of ground contamination, the following two possible solutions are presented:

[0052] First, the air outlet is connected to the air inlet 220 and / or the air inlet 260 via a line, and a flow control valve is provided on the line. The hose 270 is provided with a flow control valve for controlling the flow rate passing through the hose 270 per unit time, and when there is a lot of dirt on the floor, the flow control valve is opened wider to increase the flow rate, and when there is only a little dirt on the floor, the flow control valve is opened narrower to reduce the flow rate. The flow control valve may be a manual valve or an automatic valve. In the case of an automatic valve, it is connected to a circuit board of the floor cleaning robot and adjusts the flow rate of the flow control valve according to a command from the circuit board.

[0053] Secondly, the floor cleaning robot includes a main control circuit and a detection device used for detecting soiled objects, the detection device detects the amount of soiled objects at the current position and transmits the detection result to the main control circuit, and the main control circuit obtains a set time corresponding to the current detection result based on the detection result, and controls the floor cleaning robot to stay at the current position for the set time. In this embodiment, the detection device may be of various types, such as an infrared sensor, an image capture device, a contact detection sensor, etc. The detection sensor transmits a detected signal to the main control circuit, and the main control circuit compares the received signal with a preset signal strength-time table and searches the jet time corresponding to the signal from the table. When there is a lot of soiled objects on the floor, the main control circuit selects a corresponding long jet time, and when there is a small amount of soiled objects on the floor, the main control circuit selects a corresponding short jet time. In this way, the cleaning efficiency and effectiveness of the floor cleaning robot are both achieved.

[0054] In some embodiments, in order to improve the suction efficiency of the floor brush suction port 110, a pressure boosting protrusion 120 is further provided on the bottom of the chassis 100, located in front of the floor brush suction port 110, and multiple pressure boosting protrusions 120 are arranged at intervals in the longitudinal direction of the floor brush suction port 110, and the exhaust port 230 corresponds to the interval between two adjacent pressure boosting protrusions 120.

[0055] Specifically, in this embodiment, the booster protrusions 120 are provided in front of the floor brush suction port 110, and there is a ventilation gap between the adjacent booster protrusions 120 to allow airflow to pass through. The provision of the booster protrusions 120 reduces the wind passing area and increases the wind pressure to the floor brush suction port 110, which is favorable for the floor brush suction port 110 to suck up dirt. On this basis, the exhaust port 230 of the jet passage 210 is provided corresponding to the gap so that the airflow passing through the jet passage can quickly and reliably pass through the gap and enter the floor brush suction port 110. Here, in order to ensure the full and reasonable use of the gap, the length of the exhaust port 230 is greater than the width of the corresponding gap. In order to enhance the dust suction effect, the exhaust port 230 is located in front of the booster protrusions 120. By providing the exhaust port 230 in front of the floor brush suction port 110, the injected airflow passes through the bottom of the chassis 100 before being boosted by the booster protrusion 120, thereby avoiding mutual loss between the vertical high-velocity air pressure and the horizontal high-velocity air pressure, and by positioning the transfer position between the two in the low-pressure area, this contributes to improving the utilization rate of the airflow.

[0056] In order to ensure the boosting effect, the height of the boosting protrusion 120 gradually increases from the front side of the chassis 100 toward the floor brush suction port 110, and the maximum distance between the boosting protrusion 120 and the bottom surface of the chassis 100 is 0.5 to 5 mm. The distance between the boosting protrusion 120 and the chassis 100 is the height difference between the top of the boosting protrusion 120 and the exhaust port 230. If the height difference is too small, the distance of the roller brush from the floor is small, and the resistance of the roller brush to suck the floor is large, which is disadvantageous to the work. If the height difference is too large, the distance of the floor brush suction port 110 from the floor is too large, and at this time, the roller brush has no pressure and cannot suck up dust, resulting in poor cleaning effect.
