Description

Technical Field

[0001] This invention relates to the field of disinfection technology, and more particularly to a disinfection device for preventive medicine. Background Technology

[0002] Preventive medicine is the science that studies the impact of various environmental factors on human health and explores prevention strategies. Disinfection is an important measure in preventive medicine, preventing pathogens from invading the human body and causing disease by killing them. In preventive medicine laboratories, medical departments, and public places, disinfection of the environment and objects is necessary to protect personnel health and prevent the spread of disease. Traditional methods of manually spraying disinfectant are time-consuming, labor-intensive, and inefficient, failing to meet the needs of large-scale, frequent disinfection. Fixed disinfection devices, on the other hand, are not flexible enough, resulting in limited coverage areas and potential blind spots. Therefore, this invention proposes a disinfection device for preventive medicine. Summary of the Invention

[0003] The purpose of this invention is to provide a disinfection device for preventive medicine, which solves the problems mentioned above.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This invention discloses a disinfection device for preventive medicine, comprising an AGV trolley, a box mounted on top of the AGV trolley containing disinfectant, a rotating device on top of the box, an angle adjustment mechanism at the upper end of the rotating device, a mounting base inserted into the upper end of the angle adjustment mechanism, and a disinfection spray device detachably mounted on the upper end of the mounting base, communicating with the disinfectant; the disinfection spray device can rotate from 0° to 90° under the action of the angle adjustment mechanism, and from 0° to 180° under the action of the rotating device.

[0006] Furthermore, the disinfection spray device includes a horizontally distributed protective tube, an inclined support tube at the upper middle position of the protective tube, an elbow at the top of the support tube, a hollow shaft rotatably mounted on the elbow in the horizontal direction, a bushing cavity at the other end of the hollow shaft, and a spray head integrally formed on the outer circumference of the bushing cavity; a worm gear is integrally formed at the middle position of the hollow shaft, and a fan blade assembly is mounted on the hollow shaft to the right of the worm gear; the worm gear is rotated by a drive device; and the liquid inlet pipe passes through the protective tube and the support tube in sequence and is connected to the elbow.

[0007] Furthermore, a diagonal brace is provided on the hollow shaft at a position on the left side of the worm gear, and the other end of the diagonal brace is provided on the protective tube.

[0008] Furthermore, the hollow shaft has several liquid outlet holes equidistantly opened at one end of the bushing cavity, and several through holes are equidistantly opened on the bushing cavity; the spray head includes several horn plates equidistantly distributed on the bushing cavity, and a liquid outlet channel is formed between adjacent horn plates, and the liquid outlet channel communicates with the through holes.

[0009] Furthermore, the driving device includes a worm wheel meshing with the worm gear, the worm wheel having a gear one mounted on its central shaft, the gear one meshing with a gear two, and the gear two being driven to rotate by a forward and reverse reversing motor.

[0010] Furthermore, the angle adjustment mechanism includes a rotating block, the top of which has several insertion slots, and the bottom of which is slidably provided with an arc-shaped support plate; the bottom of the arc-shaped support plate is integrally formed with a worm gear second outer shell, and the bottom of the worm gear second outer shell is integrally formed with a chassis; a rotating shaft is provided inside the worm gear second outer shell, the bottom of which is integrally formed with a worm gear second, and the bottom of the rotating block is integrally formed with teeth that match the worm gear second; the other end of the rotating shaft passes through the worm gear second outer shell and is connected to a drive mechanism.

[0015] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0016] This invention, a disinfection device for preventive medicine, enables automated, autonomous movement by placing the container on an AGV (Automated Guided Vehicle) cart, eliminating the need for manual driving or pushing, significantly reducing labor costs and avoiding the safety risks of personnel coming into contact with disinfectant. The disinfection spray device, through an angle adjustment mechanism and a rotation device, allows for three-dimensional spray coverage, reducing blind spots.

[0030] like Figures 1-7 As shown, a disinfection device for preventive medicine includes an AGV (Automated Guided Vehicle) trolley 1. A box 2 is mounted on top of the AGV trolley 1, and the box 2 contains disinfectant. The side wall of the box 2 has a cabinet door for easy replacement of the disinfectant. A rotating device 6 is mounted on the top of the box 2, and an angle adjustment mechanism 5 is mounted on the upper end of the rotating device 6. A mounting base 4 is inserted into the upper end of the angle adjustment mechanism 5, and a disinfection spray device 3, which communicates with the disinfectant, is detachably mounted on the upper end of the mounting base 4. The disinfection spray device 3 can rotate from 0° to 90° (vertically and horizontally) under the action of the angle adjustment mechanism 5, and can rotate from 0° to 360° (horizontally) under the action of the rotating device 6.

[0031] The disinfection spray device 3 includes a horizontally distributed protective tube 301. An inclined support tube 302 is installed at the upper middle position of the protective tube 301. An elbow tube 304 is installed at the top of the support tube 302. A hollow shaft 309 is rotatably mounted on the elbow tube 304 in the horizontal direction. A shaft seal is provided between the elbow tube 304 and the hollow shaft 309 to prevent disinfectant leakage. A bushing cavity 311 is installed at the other end of the hollow shaft 309. A spray head 308 is integrally formed on the outer circumference of the bushing cavity 311. A worm gear 305 is integrally formed at the middle position of the hollow shaft 309. A fan blade assembly 307 is installed on the hollow shaft 309 to the right of the worm gear 305. The worm gear 305 is rotated by a drive device 7. An inlet pipe 306 passes through the protective tube 301 and the support tube 302 in sequence and then connects to the elbow tube 304.

[0032] A diagonal brace 303 is installed on the hollow shaft 309 at the left side of the worm gear 305, and the other end of the diagonal brace 303 is installed on the protective tube 301.

[0033] The hollow shaft 309 has a plurality of liquid outlet holes 310 equidistantly opened at one end of the bushing cavity 311, and a plurality of through holes are equidistantly opened on the bushing cavity 311; the spray head 308 includes a plurality of horn plates equidistantly distributed on the bushing cavity 311, and a liquid outlet channel 312 is formed between adjacent horn plates, and the liquid outlet channel 312 communicates with the through holes.

[0034] The drive unit 7 drives the worm gear 305 to rotate, which in turn drives the hollow shaft 309 to rotate. During rotation, the disinfectant enters the hollow shaft 309 through the inlet pipe 306 and then enters the bushing cavity 311 through the outlet hole 310. It is then sprayed out through the through hole on the bushing cavity 311 along the outlet channel 312. As the horn plate rotates at high speed with the hollow shaft 309, the disinfectant is thrown towards the edge of the horn plate under the action of strong centrifugal force, forming a very thin liquid film. When it reaches the edge, it will detach and stretch into a filament. Finally, the filamentous liquid will break into countless tiny droplets, forming an atomized state. Finally, the fan blade assembly 307 sprays the atomized disinfectant forward, expanding the disinfection range.

[0035] The driving device 7 includes a worm gear 701 that meshes with the worm gear 305. A gear 702 is mounted on the worm gear 701 via a central shaft. Gear 702 meshes with a gear 703, which is driven to rotate by a reversible motor 704. The reversible motor 704 drives gear 703 to rotate, which in turn drives gear 702 to rotate. The rotation of gear 702 causes the central shaft to rotate, which in turn drives the worm gear 701 to rotate.

[0036] The angle adjustment mechanism 5 includes a rotating block 501. The top of the rotating block 501 has several insertion slots 502. The bottom of the mounting base 4 is integrally formed with insertion blocks that mate with the insertion slots 502, allowing for quick insertion and removal for convenient operation. An arc-shaped support plate 505 is slidably mounted on the bottom of the rotating block 501. Guide strips 504 are symmetrically mounted on the arc-shaped support plate 505. A guide groove 503 matching the guide strip 504 is integrally formed on the bottom of the rotating block 501, guiding the rotation of the rotating block 501 and making its rotation more stable. A worm gear outer casing 506 is integrally formed on the bottom of the arc-shaped support plate 505, and a base 507 is integrally formed on the bottom of the worm gear outer casing 506. A rotating shaft 511 is installed inside the outer casing 506 of the second worm gear. The bottom of the rotating shaft 511 is integrally formed with a second worm gear 509. The bottom of the rotating block 501 is integrally formed with teeth 510 that match the second worm gear 509. The other end of the rotating shaft 511 extends out of the outer casing 506 of the second worm gear and is connected to a drive mechanism. The drive mechanism is a motor or a rotating handle 508.

[0037] The rotating shaft 511 is driven to rotate by the drive mechanism, which in turn drives the second worm gear 509 to rotate. The teeth 510 that mesh with the second worm gear 509 rotate along the guide bar 504 on the arc-shaped support plate 505 to achieve an angle adjustment of 0°-90°.

[0038] The rotary device 6 includes a drive shaft 601 mounted together with the bottom of the angle adjustment mechanism 5. The drive shaft 601 passes through the base 602 and is connected to a reduction motor. The base 602 has an annular groove 603. The bottom of the angle adjustment mechanism 5 is equipped with a limiting block 604 that matches the annular groove 603.

[0039] The geared motor drives the chassis 507 of the angle adjustment mechanism 5 to adjust the angle relative to the base 602 from 0° to 360° via the drive shaft 601.

[0040] The working process of this invention is as follows:

[0041] First, the AGV 1 travels along the prescribed route; second, upon reaching the disinfection location, it adjusts the angle of its 360° rotation range on the horizontal plane according to the surrounding environment; finally, based on the situation of blind spots, it adjusts the angle of its 90° rotation range perpendicular to the horizontal plane, which greatly improves disinfection efficiency, eliminates blind spots, saves labor costs, and adapts to the precise disinfection needs of multiple scenarios.

[0042] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
