[0039] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a sweeping robot, comprising a robot body 1, a liquid detection mechanism 2, a dust box 3, and a roller brush 4;

[0040] The liquid detection mechanism 2 includes a movable rod assembly 20 and a conductive metal wire 21. The movable rod assembly 20 is arranged at the bottom of the robot body 1. The conductive metal wires 21 are respectively a positive wire 22 and a negative wire 23. The positive wire 22 and the negative wire 23 are respectively wound around the movable rod assembly 20.

[0041] The liquid detection mechanism 2 is provided at the bottom of the robot body 1, the roller brush 4 is provided at the rear end of the liquid detection mechanism 2, and the dust box 3 is provided at the rear end of the roller brush 4;

[0042] Among them, when there is liquid on the ground corresponding to the bottom of the robot body 1, the positive wire 22 and the negative wire 23 will touch the liquid at the same time to achieve electrical conduction. The robot body 1 will execute the avoidance program after receiving the electrical conduction signal to make the robot body 1 leave the liquid ground.

[0043] In this embodiment, the liquid detection mechanism 2 is set to detect whether there is liquid at the bottom of the robot body 1. When it is detected that there is liquid at the bottom of the robot body 1, the liquid detection mechanism 2 can send a signal of the liquid detection to the robot body 1, so that the robot body 1 can be controlled to turn or retreat to avoid the liquid; the conductive metal wire 21 is set to detect the liquid at the bottom of the robot body 1 by winding it on the movable rod assembly 20. When the positive wire 22 and the negative wire 23 of the conductive metal wire 21 touch the liquid at the same time, the conductive metal wire 21 is electrically conductive, and the robot body 1 will start the turning or retreat program to avoid the liquid and then continue cleaning. The dust box 3 The setting of the roller brush 4 can integrate and collect the adsorbed garbage; the setting of the roller brush 4 can rotate and clean the garbage on the ground; the movable rod assembly 20 is set in front of the dust box 3 and the roller brush 4 in the forward direction, which can prevent the dust box 3 and the roller brush 4 from touching the liquid during the movement of the robot body 1. When the conductive metal wire 21 on the movable rod assembly 20 detects the presence of liquid on the ground, the conductive metal wire 21 will transmit the conductive signal to the robot body 1, and the robot body 1 will start the turning or retreat program, thereby effectively preventing the roller brush 4 from touching the liquid and causing the roller brush 4 to become wet and affect the cleaning effect, and can prevent the dust box 3 from entering with liquid and not being cleaned in time, which will cause bacteria to grow and stink. Specifically, during the movement and cleaning process of the robot body 1, the conductive metal wire 21 is wound around the movable rod assembly 20 and is located at the bottom of the robot body 1. When the positive wire 22 and the negative wire 23 in the conductive metal wire 21 touch the liquid, electrical conduction will be achieved. The conductive metal wire 21 transmits the conduction signal to the robot body 1, and the robot body 1 will start a turning or retreat program to prevent the liquid from entering the robot body 1. After avoiding the liquid, the robot body 1 continues to clean, thereby solving the problem that the machine in the prior art cannot effectively detect the presence of liquid on the ground and avoid it during the cleaning process.

[0044] like Figure 3 As shown, the robot body 1 is further provided with a lifting assembly 5, which is connected to the movable rod assembly 20. In this embodiment, the setting of the lifting assembly 5 can drive the movable rod assembly 20 to move up and down. When the robot body 1 is not working, the lifting assembly 5 can drive the movable rod assembly 20 to be retracted into the robot body 1. When the robot body 1 is working, the lifting assembly 5 can drive the movable rod assembly 20 to extend a certain distance outside the robot body 1, thereby facilitating the liquid detection mechanism 2 to detect liquid on the floor.

[0045] like Figure 3As shown, further, the lifting assembly 5 includes an electric push rod 50 and a connecting carrier plate 51. The electric push rod 50 is provided on the robot body 1 and is connected to the connecting carrier plate 51 via a movable end. The movable rod assembly 20 is connected to the connecting carrier plate 51. In this embodiment, when the robot body 1 is not started, the electric push rod 50 can drive the connecting carrier plate 51 upward through the movable end, so that the connecting carrier plate 51 drives the movable rod assembly 20 to rise and be retracted into the robot body 1; when the robot body 1 is started, the electric push rod 50 can drive the connecting carrier plate 51 downward through the movable end, so that the connecting carrier plate 51 drives the movable rod assembly 20 to descend a certain distance outside the robot body 1, so that the conductive metal wire 21 on the movable rod assembly 20 can detect whether there is liquid on the floor.

[0046] like Figure 4 As shown, further, the movable rod assembly 20 includes a support rod 201 and a swing rod 202, one side of the support rod 201 is connected to the connecting carrier plate 51, and the other side of the support rod 201 is hinged to the swing rod 202, and a through slot 13 is provided at the bottom of the robot body 1, and the swing rod 202 is inserted into the through slot 13;

[0047] When the robot body 1 is not started to clean, the electric push rod 50 drives the connecting plate 51 to rise through the movable end, and the connecting plate 51 drives the swing rod 202 to rise through the support rod 201, and the swing rod 202 extends into the robot body 1 through the through slot 13;

[0048] When the robot body 1 starts cleaning, the electric push rod 50 drives the connecting plate 51 to descend through the movable end, and the connecting plate 51 drives the swing rod 202 to descend through the support rod 201. The swing rod 202 extends out of the robot body 1 through the through slot 13.

[0049] In this embodiment, the movable rod assembly 20 is set up, the support rod 201 can be connected to the swing rod 202, and the connecting carrier plate 51 can drive the swing rod 202 to move up and down through the support rod 201. When the robot body 1 is not started to clean, the electric push rod 50 drives the connecting carrier plate 51 to rise through the movable end, so that the connecting carrier plate 51 drives the swing rod 202 to rise through the support rod 201, and the swing rod 202 extends into the robot body 1 through the through slot 13, thereby preventing the conductive metal wire 21 on the swing rod 202 from being damaged when not working and affecting the detection; when the robot body 1 starts to clean, the electric push rod 50 drives the connecting carrier plate 51 to descend through the movable end, so that the connecting carrier plate 51 drives the swing rod 202 to descend through the support rod 201, and the swing rod 202 will extend part of its length outside the robot body 1 through the through slot 13, and the conductive metal wire 21 will start to detect the ground liquid.

[0050] like Figure 6 As shown, further, a waterproof soft adhesive 203 is correspondingly provided on the through groove 13. The movable rod assembly 20 is inserted into the waterproof soft adhesive 203. A groove 2030 is provided within the waterproof soft adhesive 203, which is an interference fit with the movable rod assembly 20. The groove 2030 is funnel-shaped, with a diameter at the top of the groove 2030 being larger than a diameter at the bottom. The length of the waterproof soft adhesive 203 is shorter than the length of the movable rod assembly 20. In this embodiment, the provision of the waterproof soft adhesive 203 prevents liquid adhering to the movable rod assembly 20 from entering the robot body 1 when the movable rod assembly 20 is retracted. The funnel-shaped groove 2030 can scrape off any adhering liquid when the movable rod assembly 20 is retracted into the robot body 1. Supplementary explanation: When the movable rod assembly 20 is extended from the robot body 1, due to the interference fit between the movable rod assembly 20 and the funnel-shaped bottom of the groove 2030, the waterproof soft adhesive 203 will not affect the length of the conductive metal wire 21 that is driven by the movable rod assembly 20 and extends outside the robot body 1.

[0051] like Figure 6 As shown, the bottom of the swing link 202 is spherical, and the bottom of the support rod 201 is provided with a spherical groove 2010. The swing link 202 is connected to the spherical groove 2010 to form a spherical hinge. In this embodiment, the spherical structure of the bottom of the swing link 202 can reduce friction between the swing link 202 and the ground, which is highly practical. The spherical hinge formed by the swing link 202 and the spherical groove 2010 allows the swing link 202 to rotate 360 ​​degrees around the hinge position, achieving flexible swinging.

[0052] Furthermore, the swing rod 202 is a flexible wire;

[0053] When the sweeping robot stops working, the flexible wire is retracted into the sweeping robot, and the waterproof soft glue 203 can scrape off the water drops on the outer wall of the flexible wire.

[0054] like Figure 3 As shown, the lifting assembly 5 further includes a compression spring 53 mounting post 52 and a compression spring 53. The compression spring 53 mounting post 52 is slidably connected to the connecting carrier plate 51, and a compression spring 53 is provided between the compression spring 53 mounting post 52 and the connecting carrier plate 51. In this embodiment, the arrangement of the compression spring 53 and the compression spring 53 mounting post 52 can make the connecting carrier plate 51 more stable during lifting and lowering. The compression spring 53 provides a cushioning effect, thereby increasing the service life of the movable rod assembly 20.

[0055] In another embodiment, the robot body 1 further includes a front wheel assembly 10 and a driving wheel assembly 11, which are respectively disposed at the bottom of the robot body 1, with the front wheel assembly 10 disposed on a side away from the roller brush 4, and the driving wheel assembly 11 disposed between the roller brush 4 and the liquid detection mechanism 2. The driving wheel assembly 11 can drive the robot body 1 to move, and the front wheel assembly 10 is used to assist the robot body 1 in balanced movement.

[0056] like Figure 1 As shown, further, an ultrasonic module 12 is included;

[0057] When the ultrasonic module 12 detects that there is a carpet at the bottom of the robot body 1, the ultrasonic module 12 transmits a signal of detecting the carpet to the lifting assembly 5, and the lifting assembly 5 drives the movable rod assembly 20 to extend into the robot body 1;

[0058] When the ultrasonic module 12 detects that the bottom of the robot body 1 has passed through the carpet, the ultrasonic module 12 transmits the signal of detecting that the carpet has been passed to the lifting assembly 5, and the lifting assembly 5 drives the movable rod assembly 20 to extend a portion of its length outside the robot body 1.

[0059] In this embodiment, the ultrasonic module 12 is set to detect whether there is a carpet at the bottom of the robot body 1. When the ultrasonic module 12 detects the robot body 1, the ultrasonic module 12 transmits the signal of detecting the carpet to the lifting assembly 5, so that the lifting assembly 5 drives the movable rod assembly 20 to extend into the robot body 1, thereby preventing the conductive metal wire 21 from generating static electricity due to friction with the carpet, causing the conductive metal wire 21 to be conductive, thereby misjudging the signal of detecting liquid, resulting in the robot body 1 not cleaning the carpet; when the ultrasonic module 12 detects that the bottom of the robot body 1 has passed the carpet, the ultrasonic module 12 transmits the signal of detecting the carpet to the lifting assembly 5, so that the lifting assembly 5 drives the movable rod assembly 20 to extend a part of the length outside the robot body 1, and the conductive metal wire 21 will resume normal detection of liquid on the ground.

[0060] In another embodiment, the sweeping robot further includes a control module, and the control module is electrically connected to the liquid detection mechanism.

[0061] Furthermore, the sweeping robot further includes a lifting mechanism, which is connected to the driving wheel assembly 11 through a transmission;

[0062] When the liquid detection mechanism 2 detects the presence of liquid on the ground, the lifting mechanism will push out a certain distance, causing the driving wheel assembly 11 to extend a certain distance, so that the dust box 3 and the roller brush 4 are raised to the first position;

[0063] When the liquid detection mechanism 2 detects that the bottom of the robot body 1 has left the liquid ground, the lifting mechanism will drive the driving wheel assembly 11 to reset, so that the dust box 3 and the roller brush 4 return to the second position and resume normal operation.

[0064] In another feasible embodiment, the lifting mechanism can lift or lower the driving wheel assembly 11 by controlling it, so as to facilitate the robot body 1 to pass through the ground with less liquid; when the liquid detection mechanism 2 detects that there is less liquid at the bottom of the robot body 1, the lifting mechanism will push out a distance, so that the driving wheel assembly 11 extends a distance, so that the dust box 3 and the roller brush 4 are raised to the first position, thereby effectively preventing the dust box 3 and the roller brush 4 from touching the liquid on the ground, causing the roller brush 4 to touch the liquid and become wet, affecting the cleaning effect, and preventing liquid from entering the dust box 3 and not being cleaned in time, causing bacteria to grow and stink; when the liquid detection mechanism 2 detects that the bottom of the robot body 1 has left the liquid ground, the lifting mechanism will drive the driving wheel assembly 11 to reset, so that the dust box 3 and the roller brush 4 are restored to the second position and resume normal operation, thereby improving practicality.

[0065] By adopting the above-mentioned technical solutions, in the sweeping robot of the present invention, the liquid detection mechanism 2 can detect whether there is liquid at the bottom of the robot body 1, and detect whether there is conduction through the conductive metal wire 21. When the positive wire 22 and the negative wire 23 in the conductive metal wire 21 touch the liquid, electrical conduction will be achieved, and the conductive metal wire 21 will transmit the conduction signal to the robot body 1. The robot body 1 will start a turning or retreat program to prevent liquid from entering the robot body 1. After avoiding the liquid, the robot body 1 continues to clean, thereby solving the problem in the prior art that the machine cannot effectively detect the presence of liquid on the ground and avoid it during the cleaning process.
