Description

Technical Field

[0001] This invention relates to the field of intelligent disinfection machine technology, specifically to an intelligent disinfection robot dog for use in hospitals. Background Technology

[0002] As a core component of infection control, hospital disinfection technology has always been closely linked to public health needs, microbiological understanding, and advancements in engineering technology. With the continuous improvement of artificial intelligence technology and modern medical service levels, intelligent disinfection machines are becoming important equipment for future hospital infection control, reducing manual workload and improving disinfection efficiency.

[0003] In hospitals, it is often necessary to spray disinfectant on corridors and staircases to achieve the purpose of disinfection and sterilization. Currently, mobile intelligent disinfection machines are used. However, it is difficult to complete the disinfection task in places with step differences, such as staircases. Moreover, when the disinfectant is present for a period of time, the disinfectant will separate into layers, which will affect the subsequent disinfection effect. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art and to propose an intelligent disinfection robot dog for use in hospitals.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A smart disinfection robot dog for hospitals includes a smart robot dog with a box mounted on its bottom wall. A U-shaped support plate is fixedly connected to the bottom wall of the box. A rotating column is rotatably connected through the top wall of the U-shaped support plate. A U-shaped plate is fixedly connected to the bottom wall of the rotating column. A rotating shaft is rotatably connected to the inner side wall of the U-shaped plate. Support plates are symmetrically fixedly connected to the side wall of the rotating shaft. A spray seat is fixedly connected to both support plates. A transmission gear is fixedly connected to the side wall of the rotating shaft. A vertical plate is fixedly connected to the side wall of the U-shaped plate. An electric push rod is installed through the inner wall of the vertical plate. A rack is fixedly connected to the movable end of the electric push rod. The box is equipped with a lifting mechanism to improve the disinfection effect.

[0006] Furthermore, the inner wall of the spray seat is provided with a chamber for liquid flow, and multiple atomizing nozzles are installed on the spray seat. Multiple pipe joints are installed on the spray seat, and the transmission gear and spur rack are meshed together.

[0007] Furthermore, the lifting mechanism includes an annular box fixedly connected to the inner wall of the bottom of the box body. Multiple reciprocating screws are rotatably connected through the sealed inner wall of the annular box. Multiple stirring blades are fixedly connected to the side wall of each reciprocating screw. A mating gear is fixedly connected to the bottom end of the reciprocating screw after penetrating the inner wall of the box body. A circular block is rotatably connected through the bottom wall of the box body. The circular block can only rotate and will not produce vertical displacement. An annular toothed belt is fixedly connected to the bottom side wall of the circular block.

[0008] Furthermore, multiple power boxes are fixedly connected to the inner wall of the top of the housing. Each power box has a piston that is sealed and slidably connected inside. A nut is threaded to the side wall of the reciprocating screw. A push rod is symmetrically fixedly connected to the top wall of the nut. The end of the push rod away from the nut passes through the inner wall of the power box and is fixedly connected to the piston.

[0009] Furthermore, a one-way inlet pipe and a one-way outlet pipe are fixedly connected through the inner wall of the power box. The end of the one-way inlet pipe away from the power box is fixedly connected to the side wall of the annular box, and the end of the one-way outlet pipe away from the power box passes through the inner wall of the box and is fixedly connected to the multi-pipe joint.

[0010] Furthermore, all the mating gears are meshed with an annular toothed belt, and the threaded portion of the reciprocating screw is located on its top sidewall.

[0011] Furthermore, a motor is fixedly connected to the inner wall of the top of the housing, and a drive shaft is fixedly connected to the output end of the motor. The end of the drive shaft away from the motor is fixedly connected to the circular block.

[0012] Furthermore, an electric clamp is fixedly connected to the side wall of the U-shaped support plate. The electric clamp is sleeved on the side of the rotating column and clamps the rotating column after being energized.

[0013] Furthermore, the U-shaped plate has symmetrically opened arc-shaped holes on its sidewalls, and each of the support plates has a limit rod fixedly connected to its sidewall, with the limit rod slidably connected to the adjacent arc-shaped hole.

[0014] Furthermore, the rotating column is connected to the circular block via a one-way bearing, the rotating column is fixedly connected to the inner ring portion of the one-way bearing, and the outer ring portion of the one-way bearing is embedded and fixedly connected to the circular block.

[0015] Compared with existing technologies, the advantages of this invention are: 1. When disinfecting the hospital's staircases, the intelligent robot dog moves up the staircase step by step, turns on the motor, and through the setting of circular blocks, gears and stirring blades, each reciprocating screw drives multiple stirring blades fixed to its side wall to rotate synchronously. The stirring blades agitate and mix the disinfectant stored inside the annular box, avoiding the stratification of the disinfectant due to long-term storage, which would affect the subsequent disinfection and sterilization effect. 2. When the reciprocating screw rotates, one half of the nuts are initially positioned at the top of the threaded part of the reciprocating screw, and the other half of the nuts are initially positioned at the bottom of the threaded part of the reciprocating screw. Then, one half of the nuts will move from bottom to top first, and the other half of the nuts will move from top to bottom first, so that the sprayer will continuously spray out a mist of disinfectant. 3. When it is necessary to disinfect the side of the hospital's staircase, since the intelligent robot dog has a built-in intelligent chip and camera, the intelligent chip can control the electric push rod. By setting up structures such as a rack and pinion, support plate and arc hole, the support plate drives the spraying seat to rotate a certain angle around the pivot. Then the multiple atomizing nozzles of the spraying seat will change from facing downward to facing tilted or horizontal, which makes it convenient to spray disinfectant on the side of the hospital's staircase. 4. When the intelligent robot dog needs to spray disinfectant on both sides of its direction of travel, de-energize the electric clamp, causing the motor output to rotate in the opposite direction. The motor output then drives the circular block to rotate in the opposite direction via the drive shaft. Under the action of the one-way bearing, the one-way bearing drives the rotating column to rotate 90 degrees. The rotating column will then drive the U-shaped plate to rotate 90 degrees, thereby causing the spraying seat to rotate 90 degrees. Then, energize the electric clamp again, and the motor output will rotate clockwise to repeat the above process, completing the disinfection and sterilization of both sides of the intelligent robot dog's direction of travel.

[0020] Reference Figures 1-6 A smart disinfection robot dog for hospitals includes a smart robot dog 1. A box 2 is installed on the bottom wall of the smart robot dog 1.

A U-shaped plate 23 is fixedly connected to the bottom wall of the rotating column 20. A rotating shaft 27 is rotatably connected to the inner side wall of the U-shaped plate 23.

An electric push rod 24 is installed through the inner wall of the vertical plate. A straight rack 25 is fixedly connected to the movable end of the electric push rod 24. A lifting mechanism to improve the disinfection effect is provided on the box 2.

[0021] The inner wall of the spray seat 3 has a chamber for liquid flow, and multiple atomizing nozzles are installed on the spray seat 3. A multi-pipe connector 32 communicating with the chamber is installed on the spray seat 3, and the transmission gear 28 and the spur rack 25 are meshed together.

[0022] The lifting mechanism includes an annular box 7 fixedly connected to the inner wall of the bottom of the box 2. Multiple reciprocating screws 8 are rotatably connected through the sealed inner wall of the annular box 7. Multiple stirring blades 16 are fixedly connected to the side wall of each reciprocating screw 8. The bottom end of the reciprocating screw 8 passes through the inner wall of the box 2 and is fixedly connected to a mating gear 19. A circular block 5 is rotatably connected through the bottom wall of the box 2. The circular block 5 can only rotate and will not produce vertical displacement. An annular toothed belt 6 is fixedly connected to the bottom side wall of the circular block 5.

[0023] Multiple power boxes 10 are fixedly connected to the top inner wall of the housing 2. Each power box 10 has a piston 11 that is sealed and slidably connected inside. A nut 12 is threadedly connected to the side wall of the reciprocating screw 8. A push rod 13 is symmetrically fixedly connected to the top wall of the nut 12. The end of the push rod 13 away from the nut 12 passes through the inner wall of the power box 10 and is fixedly connected to the piston 11.

[0024] A one-way inlet pipe 14 and a one-way outlet pipe 15 are fixedly connected through the inner wall of the power box 10. The end of the one-way inlet pipe 14 away from the power box 10 is fixedly connected to the side wall of the annular box 7. The end of the one-way outlet pipe 15 away from the power box 10 passes through the inner wall of the box body 2 and is fixedly connected to the multi-pipe connector 32.

[0025] The gear 19 meshes with the annular toothed belt 6, and the threaded part of the reciprocating screw 8 is located on its top side wall.

[0026] A motor 4 is fixedly connected to the inner wall of the top of the housing 2. A drive shaft 17 is fixedly connected to the output end of the motor 4. The end of the drive shaft 17 away from the motor 4 is fixedly connected to the round block 5.

[0027] An electric clamp 21 is fixedly connected to the side wall of the U-shaped support plate 22. The electric clamp 21 is existing technology. The electric clamp 21 is sleeved on the side of the rotating column 20. After being energized, the electric clamp 21 clamps the rotating column 20.

[0028] The U-shaped plate 23 has symmetrical arc-shaped holes 30 on its sidewalls. Each support plate 29 has a limit rod 31 fixedly connected to its sidewall. The limit rod 31 is slidably connected to the adjacent arc-shaped hole 30.

[0029] The rotating column 20 is connected to the circular block 5 via a one-way bearing 18. The one-way bearing 18 is existing technology. The inner ring of the rotating column 20 and the one-way bearing 18 are fixedly connected, and the outer ring of the one-way bearing 18 and the circular block 5 are embedded and fixedly connected.

[0030] In this invention, when disinfecting the hospital's staircases, a smart robot dog 1 moves up the staircase step by step. Disinfectant is sprayed onto the surface and sides of the staircases. Motor 4, a reversible motor, is activated. When the output of motor 4 drives the drive shaft 17, which is fixedly connected to it, to rotate clockwise, the drive shaft 17 drives the circular block 5, which is fixedly connected to it, to rotate clockwise. Under the action of the one-way bearing 18, the one-way bearing 18 does not drive the rotating column 20 to rotate. The circular block 5 then drives multiple meshing gears 19 to rotate synchronously via the annular toothed belt 6 fixedly connected to its side wall. Each meshing gear 19 drives the reciprocating screw 8, which is fixedly connected to it, to rotate. During the rotation of the reciprocating screw 8, multiple stirring blades 16 fixedly connected to its side wall rotate synchronously, causing the stirring blades 16 to agitate and mix the disinfectant stored inside the annular box 7, preventing the disinfectant from separating due to long-term storage and affecting the subsequent disinfection and sterilization effect.

[0031] At the same time, when the reciprocating screw 8 rotates, one half of the nuts 12 are initially positioned at the top of the threaded part of the reciprocating screw 8, and the other half of the nuts 12 are initially positioned at the bottom of the threaded part of the reciprocating screw 8. Then, one half of the nuts 12 will move from bottom to top first, and the other half of the nuts 12 will move from top to bottom first, so that the spray seat 3 will continuously spray out a mist of disinfectant.

[0032] As the nut 12 moves upward, it drives the piston 11 to slide upward and seal inside the power box 10 via the push rod 13 symmetrically fixed to its top wall. This allows the disinfectant, which has been stirred and mixed inside the annular box 7, to be drawn into the power box 10 through the one-way inlet pipe 14. Then, as the nut 12 moves downward, it drives the piston 11 to slide downward and seal inside the power box 10 via the two push rods 13. This allows the disinfectant inside the power box 10 to be squeezed into the multi-pipe connector 32 through the one-way outlet pipe 15, and then sprayed outward through the spray seat 3 to form a mist of disinfectant, thereby increasing the disinfection range of the hospital's staircase surface.

[0033] When disinfection is needed on the sides of the hospital's staircase, the intelligent robot dog 1, equipped with a built-in intelligent chip and camera, can control the electric push rod 24. This causes the movable end of the electric push rod 24 to move the rack 25, which is fixedly connected to it, a certain distance. The rack 25 then drives the transmission gear 28, which is meshed with it, to rotate at a certain angle (less than or equal to 90 degrees). The transmission gear 28 then drives the rotating shaft 27, which is fixedly connected to it, to rotate synchronously. The rotating shaft 27 then drives the two support plates 29 to rotate synchronously. This causes the support plates 29 to drive the spraying seat 3 to rotate around the rotating shaft 27 at a certain angle. The multiple atomizing nozzles of the spraying seat 3 will then change from a downward orientation to an inclined or horizontal orientation, making it convenient to spray disinfectant on the sides of the hospital's staircase.

[0034] When the intelligent robot dog 1 needs to spray disinfectant on both sides of its direction of travel, the electric clamp 21 is de-energized, so it no longer clamps and fixes the rotating column 20. Then, the output end of the motor 4 is rotated in the reverse direction. The output end of the motor 4 drives the circular block 5 to rotate in the reverse direction through the drive shaft 17. At this time, under the action of the one-way bearing 18, the one-way bearing 18 drives the rotating column 20 to rotate 90 degrees. The rotating column 20 will then drive the U-shaped plate 23 to rotate 90 degrees, thereby causing the spraying seat 3 to rotate 90 degrees. Then, the electric clamp 21 is energized again to clamp and lock the rotating column 20, ensuring that the spraying seat 3 will not rotate. Then, the output end of the motor 4 is rotated clockwise to repeat the above process, thus completing the disinfection and sterilization of both sides of the intelligent robot dog 1 in its direction of travel.

[0035] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
