The spray unit 70 is composed of a plurality of spray heads, and the spray head is connected to the water tank on the frame 10.

[0043] Further, in the present embodiment, the dust suction unit 20 comprises: a base 21, a dust suction area 22 is provided on the bottom surface of the base 21, a dust blocking member 23 arranged in a "V" shape is provided in the dust suction area 22, a dust suction port 24 is provided at a position corresponding to the middle of the dust suction area 22 and the dust blocking member 23, a first rubber strip 25 is further provided on one side of the dust suction area 22, the first rubber strip 25 is arranged opposite to the dust blocking member 23, and the dust suction port 24 is located between the first rubber strip 25 and the dust blocking member 23;

[0044] Furthermore, the dust collection unit 20 further includes: a mounting seat 27 and a pull-out seat 35; the pull-out seat 35 is slidably arranged in the mounting seat 27, the base 21 is fixedly connected to the bottom surface of the pull-out seat 35, both ends of one side of the mounting seat 27 are sloped in a manner that expands toward the middle, the pull-out seat 35 is adapted to the mounting seat 27, and a limiting device 28 is further provided on the top surface of the mounting seat 27, the limiting device 28 is used to fix the pull-out seat 35 in the mounting seat 27, and a side wall opening 33 at one end of the mounting seat 27 is provided for the pull-out seat 35 to slide in laterally;

[0045] Furthermore, a limiting member 34 is further provided on the side wall of the mounting seat 27 away from the limiting device 28, and a limiting hole 351 adapted to the limiting member 34 is provided at one end of the drawer seat 35;

[0046] Specifically, Figure 2-Figure 7 As shown, the base 21 is fixedly arranged in the pull-out seat 35, and a dust suction area 22 is provided on the bottom surface of the base 21. The dust suction area 22 is composed of a dust shield 23 arranged in a V shape, wherein the dust shield 23 is glued and fixed to the base 21, and the direction of the inner concave is the forward direction, so that the V-shaped dust shield 23 can guide the dust to be concentrated in the middle of the dust shield 23 during the moving work, and a dust suction port 24 is also provided on the base 21, and the dust suction port 24 is connected to the external suction equipment, and the dust suction port 24 is connected to the external suction equipment. 4 is located in front of the middle of the dust shield 23. When the dust is concentrated in the middle of the dust shield 23, the dust suction port 24 sucks the dust. In this way, the sweeper can be moved first, and the dust is concentrated in the middle through the dust shield 23 before the dust suction unit 20 is turned on to suck the dust. In this way, the dust suction unit 20 is turned on only when dust suction is needed, and is turned off after the suction is completed, waiting for the next dust suction, which effectively avoids long-term uninterrupted noise pollution during the cleaning process, thereby improving the user experience.

[0047] Among them, a first rubber strip 25 is provided in front of the dust shield 23, the dust suction port 24 is located between the first rubber strip 25 and the dust shield 23, and a second rubber strip 26 is provided behind the dust shield 23. The first rubber strip 25 can prevent larger dust from entering the dust suction area 22, and cooperate with the second rubber strip 26 to form a relatively closed space in the area surrounded by the first rubber strip 25 and the second rubber strip 26 to facilitate dust suction. In order to make the space surrounded by the first rubber strip 25 and the second rubber strip 26 in a relatively closed state when the sweeper is working, the end of the first rubber strip 25 needs to be longer than or equal to the end of the second rubber strip 26 so that during the movement, the first rubber strip 25 can be A rubber strip 25 can block the angle between it and the second rubber strip 26, so as to facilitate the absorption of dust. If the end of the first rubber strip 25 is shorter than the end of the second rubber strip 26, a gap will appear in the angle between the first rubber strip 25 and the second rubber strip 26, which will easily affect the dust absorption effect. A plurality of slots are provided at the bottom of the first rubber strip 25, and the slots are used to allow dust smaller than the volume of the slots to enter the dust absorption area 22 to avoid being blocked outside the first rubber strip 25. The dust blocking member 23 is preferably a brush. The structural design of the brush can prevent dust from passing through the dust blocking member 23 when moving, so as to avoid the inability to concentrate dust or poor dust concentration effect.

[0048] The mounting seat 27 is fixedly connected to the lifting assembly 40. The bottom opening 33 of the mounting seat 27 is shell-shaped. The two ends of one side of the mounting seat 27 are respectively inclined to the middle, that is, the interval between the two ends of one side of the mounting seat 27 and the other side gradually expands, and the direction of expansion is that the closer to the middle of the mounting seat 27, the larger the interval.

When the driving chain 42 is connected to the sprocket 43, the stopper can limit the driving chain 42 to the outside of the sprocket 43 to ensure stability in use.

[0055] Among them, a main direction wheel 53 is also provided below the first end of the main bracket 48, which cooperates with the direction wheel of the frame 10 to control the moving direction. The main direction wheel 53 is a universal wheel. An auxiliary wheel 52 is also connected to the end of the two sub-brackets 50 away from the lower connecting swing arm 44 to prevent the cleaning bracket 45 from excessively descending. When the cleaning bracket 45 descends to a certain extent, the auxiliary wheel 52 will press against the cleaning bracket 45 to limit its further descent.

[0056] Working process: when the driving device 41 retracts (reverse) movement, the first end of the main bracket 48 rises under the pull of the driving chain 42, and when the first end continues to rise, due to the height difference, the second end drives the upper connecting swing arm 51 to rotate clockwise, resulting in a sinking movement. The sinking of the second end drives the sub-bracket 50 to sink, and drives the dust collection unit 20 to sink and contact the ground. When sinking, due to the limitation of the lower connecting swing arm 44, the sub-bracket 50 is prevented from shaking back and forth; when the driving device 41 extends (forward) movement, the first end of the main bracket 48 descends under its own gravity, and pushes the second end and the upper connecting swing arm 51 to rotate counterclockwise, resulting in an upward movement until it is nearly horizontal. The rise of the second end drives the dust collection unit 20 to rise and leave the ground.

[0060] Furthermore, in this embodiment, an upper connecting member 66 is fixedly provided in the cleaning frame 64, a lifting push rod 67 is connected to the middle of the upper connecting member 66, and a lower connecting member 68 is connected to the output end of the lifting push rod 67, and the lower connecting member 68 is fixedly connected to the external structure;

[0061] Specifically, Figure 11-13As shown, the high-pressure water pipe 631 is used to connect with the water tank placed on the frame 10. A plurality of water outlet holes 632 are opened on the side of the high-pressure water pipe 631 facing the cleaning rag 61. The high-speed water flow is sprayed out by the high-pressure water pipe 631 to perform preliminary cleaning on the cleaning rag 61. The high-pressure water flow is used to wash off the stubborn stains adhering to the cleaning rag 61. The cleaning rag 61 is scraped by the cleaning bristles 633. Since the cleaning rag 61 itself rotates continuously, the cleaning bristles 633 The cleaning rag 61 can be scraped and brushed without driving, and the stains can be further scraped off the cleaning rag 61; the cloth washing nozzle 634 is connected to the external suction equipment, and when the stains and sewage are scraped off the cleaning rag 61, the cloth washing nozzle 634 sucks away the stains and sewage to avoid adhering to the cleaning rag 61 again, thereby ensuring the cleaning power of the cleaning rag 61; wherein the cleaning frame 64 is used to support the cleaning rag 61, and two rollers 65 arranged at intervals are respectively arranged at both ends of the cleaning frame 64, one of the rollers 65 is connected to the driving device 41 through a belt transmission, and the roller 65 is driven to rotate by the driving device 41, and at the same time, the roller 65 contacts the cleaning rag 61, and drives the cleaning rag 61 to rotate through friction or transmission, wherein the other three rollers 65 are all freely rotatably arranged on the cleaning frame 64, and the cleaning rag 61 rotates, driving the three rollers 65 to rotate synchronously, thereby reducing the friction resistance generated on the cleaning rag 61; in order to realize the lifting and lowering of the mopping unit 60, the middle part of the upper connecting member 66 is fixed A lifting push rod 67 is connected, and a lower connecting member 68 is also connected to the output end of the lifting push rod 67. The lower connecting member 68 is fixedly connected to the frame 10. When the lifting push rod 67 is lifted, since the lower connecting member 68 is fixed and cannot move, and the mopping unit 60 is movable, the force of the lifting push rod 67 will be transmitted back to the upper connecting member 66. Through the fixed connection between the upper connecting member 66 and the cleaning frame 64, the cleaning frame 64 is driven to rise and fall, thereby realizing the lifting and falling of the mopping unit 60 as a whole relative to the frame 10.

[0062] In summary, the present application integrates the dust suction unit 20 and the mopping unit 60 in the frame 10, so that the sweeping machine can perform dust suction operations and mop operations at the same time, thereby improving the practicality of the product.
