[0018] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0019] like Figures 1-5 As shown, this application proposes a public space disinfection robot, including a robot body 1, a mounting platform 2, a storage compartment 3, a guide seat 4, an output pipe 5, a drive assembly 6, a support frame 7, a support rod 8, a nozzle 9, a conveying assembly 10, and an adjustment assembly 11. The mounting platform 2 is fixedly connected to the top of the robot body 1, the storage compartment 3 is fixedly connected to one side of the top of the mounting platform 2, the guide seat 4 is fixedly connected to the other side of the top of the mounting platform 2, and the bottom of the output pipe 5 is slidably engaged with the guide seat 4 via a snap-fit ​​plate 51. The drive assembly 6 is mounted on... The drive assembly 6 is mounted on the top of the mounting platform 2, and the end of the drive assembly 6 is connected to one end of the output pipe 5. The support frame 7 is fixedly connected to the top of the mounting platform 2. One end of the support rod 8 is rotatably connected to the inner wall of the other end of the output pipe 5. The nozzle 9 is mounted on the other end of the support rod 8. The conveying assembly 10 is mounted on the top of the support frame 7. The storage compartment 3 and the nozzle 9 are connected by the conveying assembly 10. The adjusting assembly 11 is mounted on the end of the snap plate 51, and the end of the adjusting assembly 11 is connected to the outer wall of the support rod 8.

[0020] It should be noted that the robot dog body 1, mounting platform 2, and various disinfection components described in this embodiment adopt a modular assembly structure. The mounting platform 2 is fixed to the robot dog body 1 with high-strength bolts, which can effectively prevent the disinfection components from shifting or loosening during the movement of the robot dog. The output pipe 5 adopts an anti-jamming design through the sliding cooperation between the snap-fit ​​plate 51 and the guide seat 4. With the driving action of the drive component 6 and the linkage action of the adjustment component 11, the horizontal position and tilt angle of the nozzle 9 can be flexibly adjusted. At the same time, the components are compactly arranged on the mounting platform 2, which will not occupy too much space and will not affect the flexible movement performance of the robot dog body 1, such as turning and climbing. It can be adapted to different types of public spaces such as shopping malls, stations, and corridors.

[0021] Specifically, during the operation of the epidemic prevention and killing machine dog, the machine dog body 1 autonomously moves to drive the whole killing structure on the mounting table 2 to traverse the public space. After the driving assembly 6 is started, the output pipeline 5 can be driven to reciprocate along the guide seat 4, thereby adjusting the horizontal coverage position of the spray head 9. After the adjusting assembly 11 is started, the support rod 8 can be driven to rotate relative to the output pipeline 5, thereby changing the inclination posture of the spray head 9. The conveying assembly 10 synchronously stably conveys the killing liquid in the storage bin 3 to the spray head 9 for spraying. Through the cooperation of the driving assembly 6 and the adjusting assembly 11, the position and angle of the spray head 9 can be adjusted. The problem that the angle of the spray head 9 cannot be adjusted and it is difficult to consider the killing of both open areas and narrow areas in the background technology is solved. The spray head 9 can be in a high position to realize large-area spraying in an open area, and the spray head 9 can be adjusted to extend into a corner, a gap or other narrow area for precise spraying, thereby completely eliminating the killing blind area.

[0022] As shown in Figures 1-5 the driving assembly 6 includes a mounting plate 61, a first driving device 62, a driving arm 63 and a connecting head 64. The mounting plate 61 is fixedly connected to the top of the mounting table 2. The first driving device 62 is installed on the top of the mounting plate 61. One end of the driving arm 63 is fixedly connected to the output end of the first driving device 62. The connecting head 64 is arranged between one end of the output pipeline 5 and the other end of the driving arm 63 and is connected through the connecting head 64.

[0023] It should be noted that the mounting plate 61 described in the embodiment adopts a thickened steel plate structure, which can provide stable mounting support for the first driving device 62, so as to avoid shaking of the first driving device 62 during operation. The connecting head 64 adopts a flexible universal joint structure, which can adapt to the slight angle deviation of the output pipeline 5 during sliding, so as to avoid damage of the connecting part of the output pipeline 5 and the driving arm 63 due to rigid stress. The first driving device 62 can adopt a servo motor, which can accurately control the swing amplitude of the driving arm 63, thereby accurately adjusting the sliding distance of the output pipeline 5, and ensuring that the horizontal position adjustment of the spray head 9 is accurately controllable. The first driving device 62 is a pneumatic cylinder.

[0024] Specifically, after the first driving device 62 is powered on, the driving arm 63 is driven to reciprocate around the output end thereof. The driving arm 63 drives the output pipeline 5 to synchronously move through the connecting head 64, so that the output pipeline 5 stably slides along the guide seat 4 through the clamping plate 51 at the bottom, thereby driving the spray head 9 to adjust the position in the horizontal direction. This assembly realizes flexible adjustment of the horizontal position of the spray head 9 through a mechanical transmission structure. In cooperation with the movement of the machine dog body 1, the killing coverage range can be greatly expanded, thereby solving the problem of limited coverage range of the fixed spray head 9 in the background technology, long time consumption for killing in an open area, and improving the killing efficiency in a public space.

The connection between the input pipeline 102 and the storage bin 3, the pump body 101 and the connection between the conveying pipeline 103 and the pump body 101, the spray head 9 are all provided with sealing joints, which can ensure that there is no leakage during the conveying of the disinfectant.

[0027] Specifically, the pump body 101 generates negative pressure after being powered on, the disinfectant in the storage bin 3 is extracted to the inside of the pump body 101 through the input pipeline 102, and after being pressurized by the pump body 101, it is stably conveyed to the spray head 9 through the conveying pipeline 103, and sprayed to the target area by the spray head 9. This assembly can continuously and stably convey disinfectant to the spray head 9, and the flexible pipeline design can adapt to various adjustment actions of the spray head 9, ensuring that the spray head 9 can normally spray at different positions and angles, solving the problem of poor adaptability of the fixed spray head 9 liquid supply structure in the background art, which leads to interruption of disinfection due to pipeline restrictions, and ensuring the continuity of disinfection work.

[0028] As shown in Figures 1-5 The adjusting assembly 11 comprises a fixed frame 111, a support side plate 112, a second driving device 113, a driving rod 114, a limiting plate 115 and a guide hinge seat 116, wherein the fixed frame 111 is fixedly connected to the outer wall of the clamping plate 51, the support side plate 112 is fixedly connected to the top of the fixed frame 111, the second driving device 113 is mounted on one side of the support side plate 112, one end of the driving rod 114 is fixedly connected to the output end of the second driving device 113, the limiting plate 115 is fixedly connected to the outer wall of the support rod 8, one side of the guide hinge seat 116 is slidingly clamped on the limiting plate 115, and the other side of the guide hinge seat 116 is rotatably sleeved on the other end of the driving rod 114.

The second driving device 113 is a pneumatic cylinder.

[0030] Specifically, the second driving device 113 is energized to drive the driving rod 114 to reciprocate, the driving rod 114 drives the guide hinge seat 116 at the end to move synchronously, the guide hinge seat 116 slides along the sliding groove of the limiting plate 115, and at the same time, through the rotating fit of the guide hinge seat 116 and the driving rod 114, the limiting plate 115 and the supporting rod 8 fixed thereto are driven to rotate around the rotating groove of the output pipe 5, and then the nozzle 9 is adjusted to adjust the inclination angle. This assembly realizes accurate adjustment of the angle of the nozzle 9 through a mechanical transmission structure, can adjust the nozzle 9 from a vertical state to a horizontal state, so that it can extend into narrow areas such as corners of walls and gaps of equipment, solves the problem that the fixed nozzle 9 cannot penetrate into narrow areas in the background art and is easy to form a blind area for disinfection, and realizes global disinfection without dead angle.

[0031] As shown in Figures 1-5 , the other end of the output pipe 5 is provided with a rotating groove for supporting the rotation of one end of the supporting rod 8.

[0032] It should be noted that the rotating groove in this embodiment is provided in the inner wall of the end of the output pipe 5, the inner diameter of the rotating groove is matched with the outer diameter of the supporting rod 8, the inner wall of the rotating groove is polished and treated, and lubricating grease is applied, which can further reduce the friction of the supporting rod 8 during rotation and avoid jamming. At the same time, the depth of the rotating groove is reasonably set, which can provide a stable rotating fulcrum for the supporting rod 8 and avoid axial deviation or falling of the supporting rod 8 during rotation, thereby ensuring the stability of the adjusting action.

[0033] As shown in Figures 1-5 , the top of the storage bin 3 is provided with an inlet, and the inlet is threadedly connected with a sealing cover.

[0036] It should be noted that the atomizing nozzle and the spray head 9 described in this embodiment are connected in a threaded manner, which can be detached and replaced, and different nozzle sizes can be replaced according to different disinfection scene requirements. The atomized disinfectant liquid has a wider coverage and stronger adhesion, which can improve the disinfection effect. The detachable design facilitates cleaning or replacement of the nozzle, avoiding clogging of the nozzle and affecting the spraying effect. The atomizing nozzle is made of corrosion-resistant material, which can adapt to different types of disinfectant liquid and prolong the service life.
