[0049] The technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application.

[0050] Unless otherwise defined, all technical and scientific terms used in the present application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the present application solely for the purpose of describing the particular embodiments of the present application, and is not intended to be limiting of the present application.

[0051] In order to further clarify the technical means and effects taken by the present application to achieve the predetermined purpose, the following will be described in detail in combination with the drawings and preferred embodiments.

[0052] The self-moving robot provided by the embodiments of the present application comprises a chassis, a cutting assembly and a jetting assembly. The cutting assembly and the jetting assembly are arranged on the chassis. The cutting assembly comprises a cutter mechanism arranged on one side of the chassis. Specifically, the self-moving robot can be a mower or a harvester. In this case, the cutter mechanism is a cutter disc with blades. The cutter mechanism drives the blades to rotate, so as to cut grass or crops. The embodiments of the present application take the mower as an example to describe the structure of the self-moving robot. In other embodiments, the structure of the self-moving robot can also be applied to the harvester, the sweeper or other similar devices. The present application does not limit this.

[0053] Referring to Figure 1 When the self-moving robot 100 is a mower, it can comprise a chassis 10 and a housing 20 arranged above the chassis 10. The housing 20 is buckled with the chassis 10 to form a containing cavity. The containing cavity contains the cutting assembly 30 and the jetting assembly 50 arranged on the chassis 10. The chassis 10 can be provided with a plurality of walking assemblies 21. The walking assemblies 21 are used to drive the movement of the chassis 10. The walking assemblies 21 can be driven by a motor, so as to drive the self-moving robot 100 to move. In other embodiments, the self-moving robot 100 can further comprise a handle (not shown in the figure) connected with the housing 20. The user can hold the handle to control the movement of the self-moving robot 100, so as to perform the mowing work.

[0054] Referring to Figure 2 In possible embodiments, the self-moving robot 100 provided by the present application comprises a chassis 10, a cutting assembly 30 and a jetting assembly 50. The cutting assembly 30 and the jetting assembly 50 are arranged on the chassis 10.

[0055] Specifically, referring to Figure 2 and Figure 6 The cutting assembly 30 comprises a motor 31 and a cutter mechanism 33. The motor 31 is connected with the cutter mechanism 33. The motor 31 and the cutter mechanism 33 are respectively arranged on opposite sides of the chassis 10. The output shaft of the motor 31 is connected with the cutter mechanism 33, so as to drive the cutter mechanism 33 to rotate to perform the cleaning work. In the present embodiment, the cutter mechanism 33 is provided with a plurality of blades 35. The cutter mechanism 33 drives the plurality of blades 35 to rotate, so as to perform the cutting work.

[0056] In the embodiment, the number of cutter disc mechanisms 33 is two, and the two cutter disc mechanisms 33 are arranged at intervals on the chassis 10. In other embodiments, the number of cutter disc mechanisms 33 can also be one or more, which is not limited in the application. When the number of cutter disc mechanisms 33 is two, the cutter disc mechanisms 33 are arranged side by side in the width direction of the bottom of the chassis 10 to improve the mowing efficiency. When the number of cutter disc mechanisms 33 is three, they are evenly distributed on the chassis 10 to improve the mowing efficiency and cut the grass residue more finely.

[0057] Please refer to Figure 2 、 Figure 3 and Figure 4 , the air jet assembly 50 includes an air pump 51, an air guide pipe 53 and at least one nozzle 55. The air pump 51 is in communication with the nozzle 55 through the air guide pipe 53.

[0058] Exemplarily, the air jet assembly 50 and the cutter disc mechanism 33 are arranged on opposite sides of the chassis 10, that is, the air jet assembly 50 is arranged on the same side as the motor 31. The first hole 12 is formed on the chassis 10, and the first hole 12 is arranged corresponding to the gas outlet 551 of the nozzle 55, so that the gas pumped out of the gas outlet 551 of the nozzle 55 is sprayed towards the side of the chassis 10 where the cutter disc mechanism 33 is arranged through the first hole 12.

[0059] The air pump 51 includes an air inlet 511 and a first output port 513. The air inlet 511 is in communication with the atmosphere for sucking air, and the first output port 513 is used for pumping the air sucked by the air inlet 511. The air inlet 511 can include an air duct extending in any direction, so that the air pump 51 sucks air from a suitable position and avoids impurities entering the air pump 51. The first output port 513 is connected to one end of the air guide pipe 53, so that the air is pumped out of the nozzle 55 through the air guide pipe 53.

[0060] For example, when there are two nozzles 55, the air guide tube 53 is disposed inside the self-moving robot 100, and the two nozzles 55 are connected in series. Specifically, the air guide tube 53 includes a first conduit 531 and a second conduit 533. The first conduit 531 is connected to the first output port 513 of the air pump 51 and extends around the periphery of the cutting assembly 30 to avoid interference with the arrangement position of the cutting assembly 30. It is connected to the input port of the first nozzle 55a. The first nozzle 55a has an air outlet 551 for pumping out gas and a second output port 553 connected to the second conduit 533. The second output port 553 is connected to the input port of the second conduit 533. The second conduit 533 extends around the cutting assembly 30, and the output port of the second conduit 533 is connected to the second nozzle 55b. The gas pumped out from the air pump 51 can flow through the air guide tube 53 sequentially through the first nozzle 55a and the second nozzle 55b, and thus be pumped out from the air outlet 551 of the first nozzle 55a and the air outlet 551 of the second nozzle 55b, respectively. That is, the air pump 51 draws in gas from the air inlet 511 and pumps the gas out from the first output port 513 into the first conduit 531. The first conduit 531 transmits the gas to the first nozzle 55a. Part of the gas is ejected from the air outlet 551 of the first nozzle 55a, and the other part of the gas is connected to the second conduit 533 through the second output port 553 of the first nozzle 55a. The second conduit 533 then transmits this part of the gas to the second nozzle 55b, so that the gas is finally pumped out from the first nozzle 55a and the second nozzle 55b, respectively.

[0061] For example, when there are two nozzles 55, the air pressure of the air pump 51 can be split by setting a split connector with two output ports (not shown in the figure) at the first output port 513 of the air pump 51, connecting the first conduit 531 to one output port of the split connector, connecting the output port of the first conduit 531 to the first nozzle 55a, connecting the second conduit 533 to the other output port of the split connector, and connecting the output port of the second conduit 533 to the second nozzle 55b in parallel. This will not be elaborated here.

[0062] The first nozzle 55a and the second nozzle 55b are respectively disposed at both ends of the cutter head mechanism 33, so that air is blown into the cutter head mechanism 33 from two directions at the same time, so that the impurities attached to the chassis 10 and located near the cutter head mechanism 33 can be fully covered by the airflow pumped out by the nozzles 55, thereby improving the cleaning effect.

[0063] For example, the first nozzle 55a and the second nozzle 55b are respectively disposed at both ends of the gap between the two cutter disc mechanisms 33, that is, the two nozzles 55 are simultaneously located at both ends of the two cutter disc mechanisms 33. While thoroughly cleaning the impurities around each cutter disc mechanism 33, it can also clean the impurities attached to the gap between the two cutter disc mechanisms 33, thereby improving the cleaning effect.

[0064] Exemplarily, the first nozzle 55a and the second nozzle 55b are respectively located at two ends of the chassis 10 of the self-moving robot 100 along the walking direction, ensuring to cover both sides of the chassis area, and each nozzle 55 can be arranged to spray high-pressure gas flow outward, which can effectively avoid the accumulation of grass residue at the position and prevent the hindrance or interference of the grass residue to the chassis mechanical structure.

[0065] The nozzle 55 includes a plurality of gas outlets 551 arranged in sequence. Specifically, gas is pumped out through each gas outlet 551, thereby increasing the cross-sectional area of the air outlet, and thereby facilitating the expansion of the coverage area of the gas pumped out from the nozzle 55 to the chassis 10, and thereby improving the cleaning effect.

[0066] In the present embodiment, the plurality of gas outlets 551 extend along the same direction, so that the gas pumped out through the nozzle 55 is sprayed along the same direction. In other embodiments, the orientation of the gas outlets 551 can also be set according to specific needs. For example, if the impurities on the chassis 10 of the self-moving robot 100 are more concentrated in the position between the two cutter mechanisms 33, the orientation of each gas outlet 551 can be set to extend to the position between the two cutter mechanisms 33, so that the pumped-out gas is concentratedly sprayed between the two cutter mechanisms 33. If the impurities on the chassis 10 of the self-moving robot 100 are easily distributed on the entire chassis 10, the gas outlets 551 on the nozzle 55 can be arranged to face different directions, so that the sprayed gas covers the entire chassis 10 as much as possible. The self-moving robot 100 can also include a plurality of replaceable nozzles 55, so that different nozzles 55 can be replaced according to the actual use scene, which is not limited in the present application.

[0067] Please refer to Figure 5 In the present embodiment, the angle θ between the direction of the gas flow G pumped out from the gas outlet 551 and the surface of the chassis 10 is 10°-90°. Specifically, by setting the angle θ between the gas flow G and the surface of the chassis 10, the gas flow G can blow the impurities attached to the chassis 10 when sprayed, thereby blowing the impurities off the chassis 10. Moreover, the direction of the gas outlet 551 is arranged towards the cutter mechanism 33, which can better blow off the impurities attached to the chassis 10 near the cutter mechanism 33.

[0068] Please refer to Figure 2In the embodiment, the air jet assembly 50 further comprises an air flow adjusting member 57, which is configured to adjust the air flow outputted by the air pump 51 according to the accumulation degree of impurities on the chassis 10. Specifically, the air flow adjusting member 57 can comprise a sensing part and a control part (not shown in the figure), the sensing part is configured to sense the accumulation degree of impurities on the chassis 10, so as to generate sensing data, and the control part is configured to adjust the output power of the air pump 51 according to the sensing data, so as to adjust the size of the air flow pumped by the air pump 51, the more impurities accumulated, the greater the air flow pumped, and the stronger the effect of cleaning the chassis 10.

[0069] Specifically, the sensing part can be a rotating speed measuring member electrically connected with the cutter disc mechanism 33, which is configured to detect the rotating speed of the cutter disc mechanism 33, so as to determine whether the cutter disc mechanism 33 is affected by impurities and causes the rotating speed to decrease, and the control part adjusts the output power of the air pump 51 according to the rotating speed of the cutter disc mechanism 33 sensed by the sensing part. The sensing part can also be an optical sensing member, which is arranged on the side of the chassis 10 facing the ground, and is configured to obtain optical information of the chassis 10, so as to determine the accumulation degree of impurities on the chassis 10. For example, the sensing part can be an infrared sensor, which emits infrared light to the chassis 10, and receives the reflected infrared light, so as to determine the accumulation degree of impurities on the chassis 10 according to the received optical information. According to the sensed optical information, the sensing part generates corresponding sensing data, and the control part adjusts the size of the air flow pumped by the air pump 51 according to the sensing data.

[0070] The self-moving robot 100 provided in the application can pump air flow from different positions around the cutting assembly 30 through the air jet assembly 50 further comprising two nozzles 55 located at different ends of the cutter disc mechanism 33, so as to fully clean the impurities on the chassis 10, avoid the impurities affecting the rotation of the cutter disc mechanism 33, and facilitate to ensure the working efficiency of the self-moving robot 100.

[0071] Please refer to Figure 7 Another embodiment of the self-moving robot 100 provided in the application comprises a chassis 10, a cutting assembly 30 and an air jet assembly 50. The cutting assembly 30 and the air jet assembly 50 are arranged on the chassis 10. The difference from the foregoing embodiment is that the air jet assembly 50 is arranged on the same side of the cutter disc mechanism 33 relative to the chassis 10.

[0072] Specifically, the air jet assembly 50 comprises an air pump 51, an air guide pipe 53 and two nozzles 55, the air pump 51 is fixed to one side of the chassis 10, and part of the air pump 51 is located between the cutter disc mechanism 33 and the chassis 10, the air inlet 511 of the air pump 51 extends towards the direction away from the cutter disc mechanism 33, so as to avoid the impurities near the cutter disc mechanism 33 being sucked into the air pump 51.

[0073] The air guide pipe 53 is fixed on the chassis 10, and the air guide pipe 53 is arranged around the cutter disc mechanism 33 and is closer to the chassis 10 relative to the cutter disc mechanism 33 to avoid affecting the rotation of the cutter disc mechanism 33. The first nozzle 55a and the second nozzle 55b in series on the air guide pipe 53 are respectively located on both sides of the cutter disc mechanism 33, so that air is blown to the cutter disc mechanism 33 from two directions at the same time, so that the impurities attached to the chassis 10 near the cutter disc mechanism 33 can be fully covered by the air flow pumped out by the nozzle 55, thereby improving the cleaning effect. Among them, the air guide pipe 53 includes a first conduit 531 and a second conduit 533, the first conduit 531 extends from one end of the air pump 51 around the cutting assembly 30 and communicates with the first nozzle 55a, and the second conduit 533 continues to extend around the cutting assembly 30 from the other end of the first nozzle 55a, thereby communicating with the second nozzle 55b.

[0074] Exemplarily, the first nozzle 55a and the second nozzle 55b are arranged along the front-rear direction of the vehicle body, and are respectively arranged in the gap between the two cutter disc mechanisms 33 of the chassis 10, so as to realize cleaning of the cutter disc mechanism 33 and the surrounding area from the front and rear directions. At the same time of fully cleaning the impurities around each cutter disc mechanism 33, it can also clean the impurities attached to the gap between the two cutter disc mechanisms 33, thereby improving the cleaning effect.

[0075] In the scenario of mowing grass, the front and rear ends of the chassis 10 of the self-moving robot 100 along the vehicle body are prone to accumulate grass clippings. By arranging the first nozzle 55a and the second nozzle 55b to blow air to the ground side at the front and rear ends of the chassis 10 along the vehicle body, the accumulation of grass clippings in this area can be effectively avoided.

[0076] Exemplarily, the self-moving robot 100 provided is arranged such that the air blowing assembly 50 is arranged on the same side of the cutter disc mechanism 33 relative to the chassis 10, so that the air blowing assembly 50 is located on the outer surface of the chassis 10, thereby facilitating disassembly and maintenance of the air blowing assembly 50.

[0077] The self-moving robot 100 provided in another embodiment of the present application includes a chassis 10, a cutting assembly 30, and an air blowing assembly 50.
