[0022] In the embodiment, first, the water gun head is connected to the robot through the first mounting frame 1, the second mounting frame 2 and the third mounting frame 3. The first mounting frame 1 and the second mounting frame 2 are provided with mounting holes, which can be referred to in the attached manual. Figure 1, and then let the robot cooperate with the use of the water blowing gun head, then, the clean water is sent into the water pipe 8 and flows through the connecting piece 7 to be sprayed out from the flat first nozzle 4 and the circular second nozzle 5, and a control valve 6 is installed on the water pipe 8. The control valve 6 can control the clean water to be sprayed from the flat first nozzle 4 or the circular second nozzle 5, and the flat first nozzle 4 has a wider range and the circular second nozzle 5 has a higher pressure, and then the control valve 6 controls the use of different nozzles to meet the use needs, and then the clean water passes through the flat first nozzle 4 and the circular second nozzle 5 and will be filtered by the internal filter net 10, thereby reducing impurities blocking the outlets of the flat first nozzle 4 and the circular second nozzle 5, thereby playing a role in preventing blockage.

[0023] It should be noted that the connecting piece 7 is connected to one end of the water pipe 8, and then the clean water can be sent to the flat first nozzle 4 and the circular second nozzle 5 through the connecting piece 7 along the water pipe 8. The threaded connection between the connecting piece 7 and the flat first nozzle 4 and the circular second nozzle 5 belongs to the existing mature technology, and thus the connecting piece 7 will not be described in detail.

[0024] Embodiment 2

[0025] See also Figure 1-4 A thread groove is provided at the top of the docking block 14, and the protruding portion at the bottom of the connecting block 13 is matched with the thread groove and is threadedly connected.

[0026] Preferably, the filter screen 10 is conical and connected to the connecting block 13 as a whole, and the filter screen 10 is threadedly connected to the connecting block 13 and the docking block 14 .

[0027] In the embodiment, according to the description of the above embodiment 1, the filter 10 will be clogged after long-term use. If the filter 10 needs to be replaced, at this time, the fingers are staggered at the front and rear ends of the two protrusions 12, and then the rotating protrusions 12 drive the filter 10 to rotate, and then the filter 10 drives the connecting block 13 to rotate along the threaded groove at the top of the docking block 14. As the protrusions 12 rotate, the connecting block 13 is disconnected from the docking block 14, and then the filter 10 is pulled upward, and then the filter 10 is taken out from the inside of the flat first nozzle 4 and the circular second nozzle 5, and the filter 10 can be replaced and reinstalled.

[0028] It should be noted that the filter screen 10 is conical. Figure 2 and 3 When the conical filter 10 filters impurities, the impurities slide along the surface of the filter 10, so that the impurities will be at the top of the connecting block 13, thereby alleviating the clogging of the filter 10 and preventing the clean water from flowing.

[0029] Embodiment 3

[0030] See also Figure 1-4A sealing ring 11 is installed inside the connecting member 7, and the connection end surfaces of the flat first nozzle 4 and the round second nozzle 5 are fixedly connected to the limiting block 9.

[0031] Preferably, threads are provided on the connection end surfaces of the flat first nozzle 4 and the circular second nozzle 5 , and threaded connection is formed between the flat first nozzle 4 and the circular second nozzle 5 and the connection piece 7 .

[0032] Preferably, the flat first nozzle 4 and the round second nozzle 5 are sealedly connected to the connecting member 7 via the sealing ring 11 .

[0033] In the embodiment, according to the description of the second embodiment, the flat first nozzle 4 and the circular second nozzle 5 need to be disassembled and assembled when the filter screen 10 is blocked and replaced. At this time, the flat first nozzle 4 and the circular second nozzle 5 are rotated to disengage from the connecting member 7, and then the filter screen 10 is replaced and installed. At this time, the sealing ring 11 will seal the gap between the flat first nozzle 4 and the circular second nozzle 5 and the connecting member 7, thereby playing a role in sealing and leak-proofing. At the same time, the limit block 9 is fitted with the connecting member 7, thereby reducing the exposure of the connecting ends of the flat first nozzle 4 and the circular second nozzle 5 to the outside, allowing the threads to be affected by dust, resulting in the inability to tighten the threads to the specified position, resulting in loose connection or failure.

[0034] In summary, according to the description of embodiments one to three, the filter net 10 is used to filter impurities in the water, so as to prevent the flat first nozzle 4 and the circular second nozzle 5 from being blocked by water pollution when the water blowing gun head is used, thereby playing an anti-blocking role. At the same time, the use of the sealing ring 11 improves the sealing between the flat first nozzle 4 and the circular second nozzle 5 and the connecting piece 7, thereby reducing water leakage. At the same time, the limit block 9 fits with the connecting piece 7, thereby reducing the exposure of the connecting ends of the flat first nozzle 4 and the circular second nozzle 5 to the outside, so that the threads are affected by dust, resulting in the inability to tighten the threads to the specified position, resulting in loose connections or failures.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
