[0044] The technical solution of the present utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0045] As Figures 1 to 4As shown in the figure, this embodiment provides a high-pressure water jet cleaning device, which includes an installation base 1, a cleaning structure 2 and a detection structure 3. Among them, the installation base 1 is configured to be detachably connected to the cleaning robot. An installation cavity 10 and a water inlet channel 11 are provided on the installation base 1, and the installation cavity 10 communicates with the water inlet channel 11. The cleaning structure 2 includes a nozzle pipe 21 and a nozzle 22. One end of the nozzle pipe 21 is rotatably clamped in the installation cavity 10, and the other end is connected to the nozzle 22. When the nozzle pipe 21 or the nozzle 22 is collided, the nozzle pipe 21 will rotate relative to the installation cavity 10 without deformation. A sealing component 23 is arranged between the nozzle pipe 21 and the installation cavity 10 to prevent high-pressure water from entering the gap between the nozzle pipe 21 and the side wall of the installation cavity 10. The detection structure 3 includes a control component, a sensor 31 and an induction head 32. The control component is arranged on the cleaning robot and is communicatively connected to the sensor 31. The sensor 31 is fixedly arranged on the installation base 1, and the induction head 32 is fixedly arranged on the side wall of the nozzle pipe 21. The sensor 31 can monitor the position information of the induction head 32. Under normal conditions, the induction head 32 always faces the sensor 31 directly. When the nozzle pipe 21 or the nozzle 22 rotates after being collided, the sensor 31 cannot detect the position information of the induction head 32. The sensor 31 will transmit a signal to the control component to warn the operator that the cleaning structure 2 has rotated, and remind the operator to reset the cleaning structure 2 in time to ensure the smooth progress of subsequent part cleaning. This cleaning device can effectively avoid damage to the nozzle pipe 21 caused by collision, which is beneficial to reducing the use cost.

[0046] Specifically, the control component is a single-chip microcomputer disclosed in the prior art. A relevant control program is burned on the single-chip microcomputer. The sensor 31 sends the obtained position information of the induction head 32 to the single-chip microcomputer. Combining with the control program, the control component issues a corresponding feedback signal. The sensor 31 and the induction head 32 are both existing devices disclosed in the prior art. Their specific structures and principles refer to the prior art and will not be elaborated here.

[0047] Optionally, as Figure 2 and Figure 3 shown, the installation base 1 includes a connecting flange 12 and a connecting seat 13. Among them, the connecting flange 12 is configured to be connected to the cleaning robot; the connecting seat 13 is detachably connected to the connecting flange 12, and the installation cavity 10 and the sensor 31 are both arranged on the connecting seat 13. Water inlet channels 11 are provided on both the connecting flange 12 and the connecting seat 13. Specifically, the connecting seat 13 is screwed onto the connecting flange 12, which is convenient for the assembly of this cleaning device and improves the cleaning efficiency.

[0048] Specifically, as Figure 1 shown, the sensor 31 is detachably connected to the connecting seat 13 by bolts, and the induction head 32 is also detachably connected to the side wall of the nozzle pipe 21 by bolts, which is convenient for the assembly and replacement of the sensor 31 and the induction head 32.

[0049] Furthermore, the mounting base 1 further includes a plurality of fasteners (not shown in the figure). As Figure 1 shown, the connecting flange 12 is circumferentially provided with a plurality of fastening holes 121 at intervals, and the plurality of fasteners are respectively inserted into the plurality of fastening holes 121 to realize the connection between the cleaning device and the cleaning robot.

[0051] Optionally, the sealing assembly 23 includes an end cap 231, a first sealing ring 232 and a second sealing ring 233. Among them, the end cap 231 is detachably connected to the mounting base 1, and the spray pipe 21 passes through the end cap 231 and extends into the installation cavity 10. The first sealing ring 232 is arranged between the bottom wall of the installation cavity 10 and the spray pipe 21, and the second sealing ring 233 is sleeved on the spray pipe 21 and abuts against the end cap 231 to seal the gap between the spray pipe 21 and the installation cavity 10 and the gap between the installation cavity 10 and the end cap 231, so as to prevent a large amount of high-pressure water from seeping into the installation cavity 10 and ensure the smooth progress of the cleaning process.

[0052] Specifically, in this embodiment, the end of the spray pipe 21 extending into the installation cavity 10 is spherical, and both the first sealing ring 232 and the second sealing ring 233 are spherical sealing rings.

[0053] Furthermore, an elastic member 4 is arranged between the first sealing ring 232 and the bottom wall of the installation cavity 10. Under the elastic force of the elastic member 4, the first sealing ring 232 can be stably pressed against the spray pipe 21, and at the same time, the second elastic member 4 can also stably abut against the end cap 231 to further improve the sealing performance.

[0054] Specifically, the elastic member 4 is a spring commonly used in the art. Exemplarily, referring to Figure 4 , a spring sleeve 5 is arranged between the elastic member 4 and the first sealing ring 232. The arrangement of the spring sleeve 5 can protect the spring and extend the service life of the spring.

[0055] Even further, the sealing assembly 23 further includes a plurality of connecting members 234. As Figure 4 shown, the mounting base 1 is circumferentially provided with a plurality of first connecting holes (not marked in the figure) at intervals, and the end cap 231 is circumferentially provided with a plurality of second connecting holes (not marked in the figure) at intervals. The plurality of connecting members 234 are respectively inserted into the plurality of first connecting holes and the plurality of second connecting holes to realize the detachable connection between the end cap 231 and the mounting base 1. At the same time, by screwing the connecting member 234, the compression amount of the elastic member 4 can be adjusted, ensuring the stability of the first sealing ring 232 and the second sealing ring 233, and at the same time, preventing the spray pipe 21 from being squeezed and deformed.

[0056] Exemplarily, one of the first connection hole and the second connection hole is a through hole, and the other is a threaded hole; the connecting member 234 is a commonly used bolt or screw in the art.

[0057] Optionally, the sealing assembly 23 further includes an O-ring 235. The O-ring 235 is disposed between the end cover 231 and the second sealing ring 233, and the O-ring 235 abuts against the side wall of the installation cavity 10. The above arrangement can further improve the sealing performance between the end cover 231 and the installation cavity 10.

[0058] Specifically, in this embodiment, an O-ring 235 is also provided between the spring sleeve 5 and the first sealing ring 232 to further improve the sealing performance between the spring sleeve 5 and the first sealing ring 232.

[0059] Optionally, a connection assembly 24 is provided between the nozzle tube 21 and the nozzle 22. As Figure 3 shown, the connection assembly 24 includes a union 241 and an elbow 242. One end of the union 241 is screwed onto the nozzle tube 21 in a threaded manner, and the other end is threadedly connected to the elbow 242. The end of the elbow 242 away from the union 241 is connected to the nozzle 22. The above arrangement can facilitate the assembly and replacement of the nozzle 22 and the nozzle tube 21.

[0060] Specifically, in this embodiment, the elbow 242 is a 45° elbow; in other embodiments, the elbow 242 can also be an elbow at other angles.

[0061] Optionally, the detection structure 3 further includes an alarm, and the alarm is connected to the control component. When the control component receives a signal that the sensor 31 cannot detect the position information of the sensing head 32, the alarm can emit an alarm signal to remind the operator. Specifically, the alarm signal can be a warning sound, as long as it can play a role in warning the operator, and no specific limitation is made here.

[0062] On the other hand, this embodiment also provides a cleaning robot, including the above-mentioned high-pressure water jet cleaning device, which has all the beneficial effects of the above-mentioned high-pressure water jet cleaning device, and will not be specifically described herein again.
