[0022] This application provides a cleaning robot 100. Please refer to... Figure 1 and Figure 2 The cleaning robot 100 includes a body 10, a roller brush 20, and a suction fan 30. The body 10 has a first channel 111 and a second channel 112; the first channel 111 has a first inlet 11111 and a first outlet 11121; the second channel 112 has a second inlet 1121 and a second outlet 1122. The roller brush 20 is connected to the body 10, with the first inlet 11111 located in front of the roller brush 20 along the travel direction X, and the second inlet 1121 located behind the roller brush 20 along the travel direction X. The suction fan 30 is connected to the body 10, and its air inlet connects to the first outlet 11121 and the second outlet 1122.

[0023] The body 10 can support the roller brush 20 and the suction fan 30.

[0024] The air inlet of the suction fan 30 is used for air intake. The air inlet of the suction fan 30 is connected to the first discharge port 11121 and the second discharge port 1122, meaning the suction fan 30 draws air through the first channel 111 and the second channel 112. The first discharge port 11111 and the second discharge port 1121 are inlets for collecting waste. Suction is generated at both the first discharge port 11111 and the second discharge port 1121, thus drawing waste into the first channel 111 and the second channel 112. The first discharge port 11121 is the outlet for waste in the first channel 111, allowing waste to be discharged from the first channel 111. The second discharge port 1122 is the outlet for waste in the second channel 112, allowing waste to be discharged from the second channel 112.

[0025] The direction of travel X includes the forward and backward directions of the cleaning robot 100. The first feed inlet 11111 is located in front of the roller brush 20 along the direction of travel X, that is, the first feed inlet 11111 is located on one side of the roller brush 20 along the forward direction of the cleaning robot 100.

[0026] As the cleaning robot 100 moves forward, the suction fan 30 can pre-suction the debris on one side of the roller brush 20 along the forward direction of the cleaning robot 100 through the first feed port 11111 and the first channel 111. Since debris such as hair is relatively light, the suction fan 30 can pre-suction the hair into the first channel 111 to prevent the hair from getting tangled on the roller brush 20. The roller brush 20 can push away other debris and heavier debris attached to the ground.

[0027] The second feed inlet 1121 is located behind the roller brush 20 along the traveling direction X, that is, the second feed inlet 1121 is located on the side of the roller brush 20 along the backward direction of the cleaning robot 100. The suction fan 30 can suck the garbage pushed by the roller brush 20 into the second channel 112 through the second feed inlet 1121.

[0028] When the cleaning robot 100 is used to clean up garbage, as the cleaning robot 100 moves forward, the suction fan 30 starts and generates suction in the first channel 111 and the second channel 112. The suction fan 30 sucks light garbage such as hair in front of the roller brush 20 into the first channel 111 through the first feed port 11111. Then the roller brush 20 cleans up the garbage that was not sucked into the first feed port 11111, and the suction fan 30 then sucks the garbage pushed by the roller brush 20 into the second channel 112 through the second feed port 1121.

[0029] The beneficial effects of this embodiment are as follows: By setting up a first channel 111 and a second channel 112, and connecting the air inlet of the suction fan 30 with the first discharge port 11121 and the second discharge port 1122, garbage can be sucked into the first channel 111 and the second channel 112 through the first feed port 11111 and the second feed port 1121. With the first feed port 11111 and the second feed port 1121 respectively positioned in front of and behind the roller brush 20 along the traveling direction X, when the cleaning robot 100 moves forward, the suction fan 30 can suck hair and other garbage from the area not cleaned by the roller brush 20 into the first channel 111 through the first feed port 1111, preventing hair from getting tangled on the roller brush 20. The suction fan 30 can also suck garbage pushed by the roller brush 20 into the second channel 112 through the second feed port 1121. As the cleaning robot 100 moves forward, the suction fan 30 draws in debris from the area being cleaned twice through the first feed inlet 11111 and the second feed inlet 1121, resulting in better cleaning. This embodiment of the application solves the technical problem of hair easily getting tangled on the roller brush 20.

[0030] In some embodiments, please refer to Figure 1 and Figure 2 The first channel 111 includes a feeding section 1111 and a discharging section 1112 connected to one end of the feeding section 1111. The first inlet 11111 is located at the end of the feeding section 1111 away from the discharging section 1112. The feeding section 1111 extends forward from the discharging section 1112 along the direction of travel X, and the feeding section 1111 slopes downward from the discharging section 1112 to the first inlet 11111.

[0031] One end of the feeding section 1111 is connected to the discharge section 1112 along its own extension direction, and the other end is provided with a first feed inlet 11111. The feeding section 1111 can guide the garbage sucked in by the first feed inlet 11111 into the discharge section 1112.

[0032] The discharge section 1112 can discharge waste through the first channel 111, and the first discharge port 11121 is located on the discharge section 1112.

[0033] The feeding section 1111 extends forward from the discharge section 1112 along the travel direction X, and the feeding section 1111 slopes downward from the discharge section 1112 to the first feed inlet 11111. That is, from the end where the feeding section 1111 connects to the discharge section 1112 to the first feed inlet 11111, the feeding section 1111 extends slightly downward and forward along the travel direction X towards the discharge section 1112. The extension direction of the feeding section 1111 is inclined relative to both the travel direction X and the vertical direction. After the suction fan 30 sucks the garbage into the feeding section 1111, the garbage is located on the channel wall of the feeding section 1111. The channel wall of the feeding section 1111 can support the garbage upward and prevent the garbage in the feeding section 1111 from falling downward out of the machine body 10.

[0034] In some embodiments, please refer to Figure 1 and Figure 2 The machine body 10 also has a receiving cavity 113, with part of the roller brush 20 located inside the receiving cavity 113, and the second feed port 1121 connected to the receiving cavity 113.

[0035] A portion of the roller brush 20 is located inside the receiving cavity 113, with the bottom end of the roller brush 20 needing to contact the ground, while the bottom end of the roller brush 20 is located outside the receiving cavity 113. When the portion of the roller brush 20 located outside the receiving cavity 113 rotates into the receiving cavity 113, it can push the waste into the receiving cavity 113. The second feed port 1121 is connected to the receiving cavity 113, so the suction fan 30 can easily suck the waste in the receiving cavity 113 into the second channel 112 through the second feed port 1121.

[0036] In some embodiments, please refer to Figure 1 and Figure 2 The machine body 10 has a guide wall 13 that extends downward from the bottom of the second feed port 1121 and also extends forward from the bottom of the second feed port 1121 in the direction of travel X. The roller brush 20 is used to push the garbage toward the guide wall 13, and the guide wall 13 is used to guide the garbage cleaned by the roller brush 20 to the second feed port 1121.

[0037] The guide wall 13 extends downward from the bottom end of the second feed inlet 1121. The guide wall 13 also extends forward from the bottom end of the second feed inlet 1121 along the travel direction X, meaning it extends slightly downward and forward from the bottom end of the second feed inlet 1121 along the travel direction X. The guide wall 13 is inclined relative to both the travel direction X and the vertical direction. The roller brush 20 is located in front of the second feed inlet 1121 along the travel direction X, and the guide wall 13 extends forward from the bottom end of the second feed inlet 1121 along the travel direction X, meaning it extends closer to the roller brush 20.

[0038] The roller brush 20 pushes waste towards the guide wall 13, and the guide wall 13 guides the waste cleaned by the roller brush 20 to the second feed inlet 1121. That is, the roller brush 20 can move the waste from the bottom to the top of the guide wall 13, allowing it to enter the second feed inlet 1121 from the top of the guide wall 13. Since the guide wall 13 extends slightly upwards and backwards from the roller brush 20 along the travel direction X, when the roller brush 20 rotates in direction P, the bristles or strips at the bottom of the roller brush 20 first pass behind the axis of the roller brush 20 along the travel direction X and then rotate upwards. The roller brush 20 can push the waste upwards and backwards along the travel direction X, allowing it to enter the second feed inlet 1121 along the guide wall 13. Direction P is the direction about the axis of rotation of the roller brush 20. For example, as shown... Figure 1 and Figure 2 As shown, direction P is counterclockwise around the axis of rotation of the roller brush 20.

[0039] Optionally, the end of the guide wall 13 away from the second feed inlet 1121 is located directly below a portion of the structure of the roller brush 20, making it easier for the roller brush 20 to push the waste onto the guide wall 13. Optionally, in the direction of the rotation axis of the roller brush 20, the bristles or strips of the roller brush 20 are located between the two ends of the guide wall 13, allowing the roller brush 20 to push the waste onto the guide wall 13 from different positions.

[0040] The beneficial effects of this application embodiment are as follows: the guide wall 13 extends from the second feed port 1121 to the roller brush 20, and the roller brush 20 pushes the garbage towards the guide wall 13, which can push the garbage along the extension direction of the guide wall 13 and approach the second feed port 1121. The suction fan 30 can stably suck the garbage swept by the roller brush 20 into the second channel 112 through the second feed port 1121.

[0041] In some embodiments, please refer to Figure 1 and Figure 2The body 10 also has a dust collection chamber 123, which is connected to the first discharge port 11121 and the second inlet port 1121; the cleaning robot 100 also includes a filter 40 connected to the body 10, and the air inlet of the blower 30 is connected to the dust collection chamber 123 through the filter 40.

[0042] The dust collection chamber 123 can hold waste. The first discharge port 11121 and the second discharge port 1122 are the waste outlets of the first channel 111 and the second channel 112, respectively. The dust collection chamber 123 is connected to the first discharge port 11121 and the second discharge port 1122, and the air inlet of the suction fan 30 is connected to the dust collection chamber 123. That is, the suction fan 30 is connected to the first discharge port 11121 and the second discharge port 1122 through the dust collection chamber 123, and the suction fan 30 can suck the waste in the first channel 111 and the second channel 112 into the dust collection chamber 123.

[0043] The filter 40 allows air to pass through and filters out debris. The air inlet of the suction fan 30 is connected to the dust collection chamber 123 through the filter 40. In other words, the filter 40 separates the air inlet of the suction fan 30 from the dust collection chamber 123. The filter 40 can prevent debris in the dust collection chamber 123 from entering the suction fan 30, and the suction fan 30 can draw air from the dust collection chamber 123 into the suction fan 30.

[0044] The beneficial effects of this embodiment are as follows: the dust collection chamber 123 can collect the garbage sucked up by the suction fan 30 through the first channel 111 and the second channel 112, making it convenient to clean up the garbage uniformly after the cleaning robot 100 has finished cleaning. The filter 40 can prevent the garbage in the dust collection chamber 123 from entering the suction fan 30, and can also allow the suction fan 30 to draw in air, so that the suction fan 30 can operate stably.

[0045] In some embodiments, please refer to Figure 1 and Figure 2 The cleaning robot 100 also includes a partition 50 connected to the body 10. The partition 50 is located in the dust collection chamber 123 and divides the dust collection chamber 123 into a first chamber 1231 and a second chamber 1232. The partition 50 is provided with a vent 51 that connects the first chamber 1231 and the second chamber 1232. The first chamber 1231 is connected to the first feed inlet 11111, and the second chamber 1232 is connected to the second feed inlet 1121. The air inlet of the suction fan 30 is connected to the first chamber 1231 through a filter 40.

[0046] The partition 50 separates the waste in the first chamber 1231 and the second chamber 1232. Optionally, the partition 50 can be horizontally arranged, with its thickness direction aligned with the vertical direction, and the first chamber 1231 and the second chamber 1232 located on opposite sides of the partition 50 along the vertical direction. Optionally, the partition 50 can also be vertically arranged, with its thickness direction aligned with a horizontal direction, and the first chamber 1231 and the second chamber 1232 located on opposite sides of the partition 50 along the horizontal direction.

[0047] The air inlet of the suction fan 30 is connected to the first chamber 1231 through the filter 40, and the first chamber 1231 is connected to the first feed inlet 11111. Thus, the suction fan 30 is connected to the first feed inlet 11111 through the filter 40 and the first chamber 1231, and the suction fan 30 can suck the garbage in the first channel 111 into the first chamber 1231.

[0048] The first chamber 1231 is connected to the second chamber 1232 through the vent 51. The suction fan 30 is connected to the second chamber 1232 through the filter 40 and the first chamber 1231. The second chamber 1232 is connected to the second feed inlet 1121. The suction fan 30 is connected to the second feed inlet 1121 through the filter 40, the first chamber 1231, and the second chamber 1232, allowing it to draw waste from the second channel 112 into the second chamber 1232. Optionally, multiple vents 51 can be provided, with each individual vent having a smaller diameter and the overall cross-sectional area of ​​the multiple vents 51 being larger. This ensures effective ventilation while allowing the partition 50 to separate the waste in the first chamber 1231 and the second chamber 1232.

[0049] The cleaning robot 100 typically sweeps up debris as it moves forward. The first feed inlet 11111 is located in front of the roller brush 20 along the direction of travel (X). As the cleaning robot 100 moves forward, the suction fan 30 draws debris such as hair from areas not cleaned by the roller brush 20 into the first channel 111 via the first feed inlet 1111 and ultimately into the first chamber 1231. After the roller brush 20 sweeps up debris adhering to the ground and larger pieces of debris, the suction fan 30 draws the debris from the roller brush 20 into the second channel 112 via the second feed inlet 1121 and ultimately into the second chamber 1232.

[0050] A partition 50 is provided between the second chamber 1232 and the filter 40. The partition 50 can prevent the garbage in the second chamber 1232 from moving towards the filter 40, thereby reducing the amount of large garbage adsorbed on the filter 40.

[0051] Optionally, the end of the first channel 111 away from the first chamber 1231 is a funnel-shaped structure, and the opening of the first feed port 11111 is relatively large, which makes it easier to suck up hair on the ground more efficiently.

[0052] The beneficial effects of this embodiment are as follows: A partition 50 divides the dust collection chamber 123 into a first chamber 1231 connected to the first air inlet and a second chamber 1232 connected to the second air inlet, and a ventilation hole 51 is provided on the partition 50. When the cleaning robot 100 moves forward, the suction fan 30 can suck hair and other debris from areas not cleaned by the roller brush 20 into the first chamber 1231 through the first feed inlet 11111, and can also suck debris cleaned by the roller brush 20 into the second chamber 1232 through the second feed inlet 1121. The partition 50 separates the debris in the first chamber 1231 and the second chamber 1232, allowing for separate processing of hair and other debris after cleaning. The suction fan 30 is connected to the first chamber 1231 through the filter 40. A partition 50 is provided between the second chamber 1232 and the filter 40. The partition 50 can prevent the garbage in the second chamber 1232 from moving to the filter 40, thereby reducing the garbage adsorbed on the filter 40 and enabling the filter 40 to ventilate stably.

[0053] In some embodiments, please refer to Figure 1 and Figure 2 The first chamber 1231 is located above the second chamber 1232. The first chamber 1231, the partition 50, and the second chamber 1232 are arranged sequentially from top to bottom.

[0054] When the cleaning robot 100 moves forward to clean up debris, the suction fan 30 sucks hair and other debris into the first chamber 1231, and sucks other small particles of debris attached to the ground into the second chamber 1232. By positioning the first chamber 1231 above the second chamber 1232, larger, lightweight debris such as hair is less likely to fall into the second chamber 1232 through the vent 51. When the suction fan 30 stops, small particles of debris such as dust can fall into the second chamber 1232 through the vent 51. After cleaning, hair and other small particles can be cleaned separately.

[0055] In some embodiments, please refer to Figure 1 and Figure 2 At least part of the first channel 111 extends upward from the first discharge port 11121 to the outside of the first chamber 1231, and other parts of the first channel 111 may extend upward or in other directions.

[0056] The beneficial effect of this application embodiment is that: a portion of the first channel 111 extends upward from the first discharge port 11121 to the outside of the first chamber 1231, so the garbage in the first chamber 1231 is difficult to move upward from the first discharge port 11121 into the first channel 111, thus preventing the garbage in the first chamber 1231 from falling out of the machine body 10 from the first channel 111.

[0057] In some embodiments, please refer to Figure 1 and Figure 2 At least part of the first channel 111 extends horizontally from the first discharge port 11121 to the outside of the first chamber 1231, and the other part of the first channel 111 may extend upward or in other directions.

[0058] The beneficial effect of this application embodiment is that: part of the first channel 111 extends horizontally from the first discharge port 11121 to the outside of the first chamber 1231, which can prevent the garbage in the first chamber 1231 from falling out of the machine body 10 from the first channel 111 under the action of gravity.

[0059] In some embodiments, please refer to Figure 1 and Figure 2 At least part of the second chamber 1232 is located below the second discharge port 1122.

[0060] Optionally, a portion of the second chamber 1232 may be located below the second discharge port 1122, and another portion of the second chamber 1232 may be at the same height as the second discharge port 1122. The overall height of the second chamber 1232 and the second channel 112 is relatively small, resulting in a more compact structure for the machine body 10. Optionally, the entire second chamber 1232 may also be located below the second discharge port 1122.

[0061] The beneficial effects of this application embodiment are as follows: at least part of the second chamber 1232 is located below the second discharge port 1122, so the garbage in the second chamber 1232 falls below the second discharge port 1122 under the action of gravity, and the garbage in the second chamber 1232 is difficult to move upward from the second discharge port 1122 into the second channel 112, thus preventing the garbage in the second chamber 1232 from falling outside the machine body 10 from the second channel 112.

[0062] In some embodiments, please refer to Figures 1 to 3 The body 10 includes a support body 11 and a dust box 12. The dust box 12 is detachably connected to the support body 11, and the dust collection chamber 123 is located inside the dust box 12.

[0063] The support body 11 can support the roller brush 20, the suction fan 30 and the dust box 12.

[0064] The dust box 12 is detachably connected to the support body 11, and the dust collection chamber 123 is located inside the dust box 12. The dust box 12 can be removed from the support body 11 and the garbage in the dust collection chamber 123 can be emptied, which can quickly clean the garbage in the dust collection chamber 123.
