[0029] This application proposes a self-cleaning device 100 for a track robot 300, which is applied to a robot charging dock 200. When the track robot 300 enters the chamber of the robot charging dock 200, the self-cleaning device 100 performs cleaning work on the track robot 300. Please refer toFigures 1 to 4 In an embodiment of the present application, the robot charging dock 200 includes a housing 201 installed on the track 400. The housing 201 is provided with a bin for the track robot 300 to dock. The self-cleaning device 100 includes a centrifugal fan 10, an air outlet pipeline 20, and an air outlet nozzle assembly 30.

[0030] It can be understood that the track robot 300 is provided with a battery to store electrical energy to maintain daily work through electrical energy. When the electrical energy of the track robot 300 is too low, the track robot 300 cannot work properly or even cannot work. Therefore, the track robot 300 needs to move to the robot charging dock 200 regularly to replenish electrical energy in time.

[0031] The centrifugal fan 10 is fixedly arranged on the housing 201. The air outlet nozzle assembly 30 includes a movably arranged nozzle 33. The air outlet nozzle assembly 30 is installed on the housing 201 and is located at the entrance 202 of the bin. The air outlet of the centrifugal fan 10 is communicated with the nozzle 33 through the air outlet pipeline 20 to blow air on the track robot 300 entering the bin through the nozzle 33.

[0032] It should be noted that the bin of the housing 201 usually has an entrance 202 and an exit. In one embodiment, the entrance 202 and the exit of the bin are the same opening, that is, the track robot 300 can enter or leave the bin along the same opening. In another example, the entrance 202 and the exit of the bin are different openings, that is, the track robot 300 can enter the bin along one opening and leave the bin along another opening. Considering the self-cleaning device 100 proposed in the present application, which is applied to the robot charging dock 200, a clean surface of the track robot 300 is convenient for electrical connection with the charging dock. Therefore, in the present application, the air outlet nozzle assembly 30 is movably arranged on the housing 201 and is located at the entrance 202 of the bin.

[0033] There are various ways to install the air outlet nozzle assembly 30 on the housing 201. The air outlet nozzle assembly 30 can be installed on the housing 201 by a detachable fixed connection method, such as: screw connection, snap connection; the air outlet nozzle assembly 30 can also be installed on the housing 201 by a non-detachable fixed connection method, such as: welding, riveting; the air outlet nozzle assembly 30 can also be installed on the housing 201 by a movable connection method, such as: rotational connection. Considering that in the present application, the air outlet nozzle assembly 30 includes a movably arranged nozzle 33, preferably, the air outlet nozzle assembly 30 is installed on the housing 201 by a fixed connection method.

[0034] Through the above technical solution, the air outlet nozzle assembly 30 of the present application includes a movably arranged nozzle 33. The air outlet nozzle assembly 30 is installed on the housing 201 and is located at the entrance 202 of the bin body. The air outlet of the centrifugal fan 10 is communicated with the air outlet nozzle assembly 30 through an air outlet pipeline 20. In this way, when the self-cleaning device 100 enters the bin body of the robot charging dock 200, the movably arranged nozzle 33 can change the orientation of the nozzle 33 to adjust the air flow direction generated by the centrifugal fan 10, and then blow air on the track robot 300 entering the bin body through the nozzle 33 to efficiently clean the surface of the track robot 300. It can be seen that the technical solution of the present application can efficiently clean the surface of the track robot 300 to avoid the problem that dust accumulates on the surface of the track robot 300 for a long time, forming a dust accumulation that affects the normal operation of the track robot 300. In addition, the clean surface of the track robot 300 also facilitates the establishment of a stable electrical connection between its power receiving contacts and the electrodes of the robot charging dock 200, and also reduces the participation of manual labor.

[0035] In some examples, such as Figure 1 and Figure 2 shown, the self-cleaning device 100 includes two air outlet nozzle assemblies 30. The two air outlet nozzle assemblies 30 are located above the track 400 and are spaced apart on both sides of the track 400. Such a setting aims to further improve the cleaning efficiency of the self-cleaning device 100 for the track robot 300.

[0036] In some examples, such as Figures 1 to 4 shown, the air outlet nozzle assembly 30 includes a mounting base 31 and a movable base 32. The mounting base 31 is installed on the housing 201, the movable base 32 is rotatably installed on the mounting base 31, and the nozzle 33 is fixedly installed on the movable base 32. Such a setting aims to change the orientation of the nozzle 33 by rotating the nozzle 33 to adjust the air flow direction generated by the centrifugal fan 10, so as to further improve the cleaning efficiency of the self-cleaning device 100 for the track robot 300.

[0037] Preferably, the mounting base 31 is fixedly installed on the housing 201 by means of threaded connection.

[0038] In some examples, such as Figure 4As shown in the figure, the mounting base 31 includes two mounting plates 311 and a connecting plate 312. The connecting plate 312 is connected to the housing 201. The two mounting plates 311 are fixedly connected to the opposite sides of the connecting plate 312 respectively and are arranged in parallel with each other. The movable seat 32 includes two movable plates 321 and a fixing plate 322. The fixing plate 322 is fixedly installed with a spray head 33. The two movable plates 321 are fixedly connected to the opposite sides of the fixing plate 322 respectively and are arranged in parallel with each other. One ends of the two movable plates 321 away from the fixing plate 322 are respectively rotatably connected to the corresponding mounting plates 311. Such a setting aims to improve the stability of the spray head 33 and facilitate the rotation of the spray head 33.

[0039] In some examples, as Figure 4 shown, the mounting plate 311 is provided with a track groove 313 having a preset track, and the movable plate 321 is convexly provided with a limit protrusion 323 inserted and matched with the track groove 313. Such a setting aims to limit the rotation stroke range of the spray head 33 through the insertion and matching of the limit protrusion 323 and the track groove 313, making the spray head 33 easier to control. In addition, the spray head 33 is more stable during the rotation process.

[0040] In some examples, as Figure 1 shown, an air filter 40 is also connected and provided at the air inlet of the centrifugal fan 10. Such a setting aims to improve the cleanliness of the air flow generated by the centrifugal fan 10, thereby improving the cleaning efficiency of the air flow. In addition, the air flow with high cleanliness can prevent dust from clogging the centrifugal fan 10 and affecting the normal operation of the centrifugal fan 10.

[0041] In some examples, as Figure 1 and Figure 2 shown, the self-cleaning device 100 further includes an air inlet pipeline 50. One end of the air inlet pipeline 50 is connected and provided with the air inlet, and the other end of the air inlet pipeline 50 extends in a direction away from the air inlet and is connected and provided with an air filter 40. Such a setting aims to arrange the air filter 40 in a place with a better air environment through the air inlet pipeline 50 and improve the service life of the air filter 40.

[0042] In some examples, as Figure 1 shown, the self-cleaning device 100 further includes a position sensor 60. The position sensor 60 is installed on the housing 201 and is located at the entrance 202 of the bin body. The position sensor 60 is used to detect the track robot 300. The position sensor 60 is also communicatively connected to the centrifugal fan 10 to transmit detection information to the centrifugal fan 10, and the centrifugal fan 10 starts to work according to the detection information.

[0043] There are many types of the in-place sensor 60. The in-place sensor 60 may be a proximity switch. When the track robot 300 moves along the track 400 to a preset position, the proximity switch is triggered by the track robot 300 and generates a trigger signal. When the track robot 300 moves along the track 400 and deviates from the preset position, the in-place sensor 60 is not triggered and does not generate a trigger signal.

[0044] The in-position sensor 60 can also be a micro switch. When the track robot 300 moves along the track 400 to a preset position, the track 400 inspection robot contacts and triggers the micro switch. After the micro switch is triggered, a trigger signal is generated. When the track robot 300 moves along the track 400 and is completely offset from the preset position, the micro switch is not triggered and no trigger signal is generated.

[0045] Such a configuration is intended to improve the intelligence of the self-cleaning device 100 through the in-place sensor 60, so as to reduce energy consumption while improving the cleaning efficiency of the self-cleaning device 100 on the track robot 300.

[0046] In one example, a timing relay is further provided in the power supply circuit of the centrifugal fan 10 to control the time for the self-cleaning device 100 to clean the track robot 300 through the timing relay.

[0047] In another example, a status indicator light is further provided in the power supply circuit of the centrifugal fan 10 to remind whether the self-cleaning device 100 is in a working state through the status indicator light.

[0048] In some examples, such as Figures 1 to 3 As shown, the self-cleaning device 100 further includes a box body 70 with a built-in mounting cavity 71, the box body 70 is fixedly mounted on the housing 201, and the centrifugal fan 10 is fixedly mounted on the mounting cavity 71, so as to be fixedly mounted on the housing 201 through the box body 70. Such a setting is intended to protect the centrifugal fan 10 from interference from external factors through the box body 70. At the same time, the mounting cavity 71 can also be used to install and fix other components of the self-cleaning device 100.

[0049] In some examples, such as Figure 2 and Figure 3 As shown, the shell 201 is also provided with a mounting hole connected to the mounting cavity 71, and the air outlet duct 20 includes a first air outlet section 21, a second air outlet section 22 and a connector 23. The connector 23 is installed in the mounting hole and is partially exposed on the outer surface of the shell 201. One end of the first air outlet section 21 is connected to the air outlet, and the other end of the first air outlet section 21 is fixedly connected to the connector 23 and connected. One end of the second air outlet section 22 is detachably fixedly connected to the connector 23 and connected, and the other end of the second air outlet section 22 is connected to the nozzle 33.

[0050] With such a setting, it is aimed to improve the modularity of the self-cleaning device 100, so that while the self-cleaning device 100 can be adapted to different robot charging docks 200, it is also convenient for the self-cleaning device 100 to be installed on the housing 201.

[0051] The above are only alternative embodiments of the present application, and do not limit the patent scope of the present application accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present application under the inventive concept of the present application, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
