The chemical drugs used for disinfection are called disinfectants. Airborne transmission is an important route of transmission for pathogenic microorganisms. Spray disinfection of the air is an important method to prevent the spread of pathogenic microorganisms. Patent: CN2609554Y relates to the structure of an air collection and disinfection device in a ward.

The device has a reasonable structure, is easy to install and use, has low cost, is fully capable of effectively collecting the air in the atypical pneumonia ward and effectively killing the SARS virus therein, and has the advantage of not polluting the environment; In the above-mentioned technology, the position of the exhaust pipe is fixed at different levels, and the range of the purified air sprayed out is limited, resulting in slow air purification efficiency.

It simply diverts the flow into the disinfectant, which cannot ensure that the disinfectant is in complete contact with the air. Improvement is needed.

[0019] like Figure 1 and Figure 5 As shown, the linkage mechanism 4 includes two fixed blocks 401, a guide rod 402 is fixedly connected between the two fixed blocks 401, a connecting piece 403 is slidably connected to the outer wall of the guide rod 402, a rack 404 is integrally formed at the front end of the connecting piece 403, a sector gear 405 is meshedly connected to the front surface of the rack 404, and a through-type adjustment slot 406 is formed on the upper surface of the sector gear 405. A screw 407 is rotatably connected to the interior of the adjustment slot 406 via a rotating shaft, and a screw block 408 is threadedly connected to the outer wall of the screw 407; The front end of the screw 407 passes through the front end of the sector gear 405 and is fixedly connected to the knob 409. The bottom of the fixed block 401 is fixedly connected to the upper surface of the disinfection box 1. The lower surface of the sector gear 405 is rotatably connected to the upper surface of the disinfection box 1 through a rotating shaft. When the motor 302 is started, the sector gear 405 will be driven to swing back and forth through the traction rod 307, so that the engagement of the sector gear 405 with the rack 404 can drive the connecting piece 403 to move back and forth left and right along the outer wall of the guide rod 402. The screw rod 407 is rotated and the screw block 408 is controlled to move by the hand-held knob 409, so that the amplitude of the reciprocating swing of the sector gear 405 is controlled to be different during the movement of the traction rod 307, thereby controlling the amplitude of the repeated left and right movement of the connecting piece 403.

[0020] like Figure 1 、 Figure 6 Shown and Figure 7 The lifting mechanism 7 includes a lifting seat 701, the inner side of the lifting seat 701 is rotatably connected to a screw rod 2 702 via a rotating shaft, the outer wall of the screw rod 2 702 is threadedly connected to a screw block 2 703, the top of the screw rod 2 702 is located above the lifting seat 701 and is fixedly connected to an eccentric disk 3 704, the upper surface of the eccentric disk 3 704 is rotatably connected to a traction rod 2 705 via a rotating shaft, and the left end of the traction rod 2 705 is rotatably connected to the upper surface of the connecting piece 403 via a rotating shaft; A notch 706 is provided on the upper surface of the second screw block 703, and a cylinder 707 is provided inside the notch 706. A spiral groove 708 is slidably connected to the outer wall of the cylinder 707, and a toggle column 709 is slidably connected to the inner side of the spiral groove 708. A toggle rod 710 is fixedly connected to the top of the toggle column 709. A spring 711 is fixedly connected between the toggle rod 710 and the spiral groove 708. The right end of the toggle rod 710 passes through the front of the second screw block 703 and is fixedly connected to a trapezoidal pressure block 712. A plurality of blocking blocks 713 are fixedly connected to the inner front surface of the lifting seat 701. The upper surface of the base 10 is fixedly connected to the bottom of the lifting seat 701 and the bottom of the atomizing pump 5; The front and rear ends of the atomizing nozzle 8 are fixedly connected to the shaft column 3 9. The front and rear ends of the shaft column 3 9 respectively pass through the interior of the two recesses 706 and are fixedly connected to the opposite sides of the two cylinders 707. The second screw rod 702 is a screw rod with a large pitch. A single rotation can control the second screw block 703 to descend a large distance, thereby increasing the single movement range. During the repeated left and right movement of the connecting piece 403, or by driving the eccentric disk 3 704 to rotate back and forth through the second traction rod 705, the second screw rod 702 can be controlled to rotate back and forth, thereby controlling the second screw block 703 to move up and down repeatedly, and then controlling the atomizing nozzle 8 to move up and down repeatedly, thereby increasing the spray range of the purified gas. Moreover, since the movement range of the connecting piece 403 can be adjusted, the range of the repeated up and down movement of the atomizing nozzle 8 can be adjusted, thereby controlling the spray range of the purified air according to the different sizes of the wards, thereby improving the applicability of the device and improving its applicability. In addition, during the repeated up and down movement of the screw block 703, the trapezoidal pressure block 712 will be blocked by multiple blocks 713, and then with the cooperation of the spring 711, the toggle rod 710 will be controlled to move left and right repeatedly, thereby toggling the cylinder 707 back and forth through the cooperation of the toggle column 709 and the spiral groove 708, so that the atomizing nozzle 8 can swing back and forth during the up and down movement, further improving the spray range, compensating for the problem of incomplete spraying during the up and down movement, further improving the disinfection range, and better disinfection range, which can avoid excessive spraying or omission in local areas.

[0021] Working process: When the device is started, the vacuum pump 12 is started to extract the waste air with viruses in the ward. During the extraction, the dust in the air will be filtered through the filter box 13. The extracted air with viruses will be introduced into the disinfection box 1 through the output end. The introduced waste air with viruses will be mixed with the disinfection liquid pre-stored in the disinfection box 1. The motor 302 in the drive mechanism 3 starts running, and its output shaft drives the eccentric disk 1 303 to rotate, which in turn causes the eccentric disk 2 305 to rotate synchronously via the shaft 1 304. During this process, the engaging head 308 at the bottom of the shaft 2 306 drives the engaging seat 205 of the stirring mechanism 2 to rotate, thereby driving the stirring shaft 203 and stirring rod 204 to fully stir the disinfectant in the disinfection box 1, ensuring that the disinfectant is fully mixed with the waste air containing viruses drawn into the disinfection box 1. At the same time, shaft 1 (304) on the outside of eccentric disc 1 (303) pulls screw 1 (408) via traction rod 1 (307). Because screw 1 (408) is located within adjustment slot 406 of linkage mechanism 4 and is threadedly connected to screw 1 (407), its movement drives sector gear 405 to oscillate back and forth around the axis of rotation. Sector gear 405 meshes with rack 404, pushing connecting piece 403 to slide left and right along guide rod 402, ultimately driving eccentric disc 3 (704) of lifting mechanism 7 to rotate via traction rod 2 (705). The rotation of eccentric disk 3 704 drives screw 2 702 to rotate, causing screw block 2 703 to move up and down along screw 2 702, thereby achieving the lifting and lowering of atomizing nozzle 8. During the lifting and lowering process of screw block 2 703, the trapezoidal pressure block 712 above it will squeeze the block 713 inside the lifting seat 701. The pressure of trapezoidal pressure block 712 drives the toggle rod 710 to compress spring 711, which slides within the spiral groove 708 through the toggle column 709, ultimately causing the cylinder 707 to drive the atomizing nozzle 8 to swing back and forth, achieving dynamic adjustment of the spray angle. The above configuration significantly improves the existing technology and achieves multiple functions: The vacuum pump 12 extracts the waste air containing viruses in the ward, and during the extraction, the dust and the like in the air are filtered through the filter box 13. The extracted virus-containing air is introduced into the disinfection box 1 through the output end. The introduced virus-containing waste air is mixed with the disinfection liquid pre-stored in the disinfection box 1, effectively extracting and purifying the virus-containing air in the ward. The stirring mechanism 2 is detachable. The side plate 201 is detachably connected to the disinfection box 1 by bolts, and the bottom plate 202 is engaged with the inner side of the disinfection box 1. When cleaning is required, the bolts can be directly removed, and the stirring shaft 203 and the stirring rod 204 can be pulled out from the disinfection box 1. This effectively prevents the adhesion of impurities after long-term use and affects the disinfection effect. The detachable design of the stirring mechanism 2 allows cleaning to be completed quickly. Compared with the traditional fixed stirring structure, the maintenance efficiency is significantly improved, effectively reducing equipment failures and attenuation of disinfection effects caused by residual impurities. The adjustment function of linkage mechanism 4: By rotating knob 409, screw rod 1 407 rotates, adjusting the position of screw block 1 408 within adjustment slot 406. The change in the position of screw block 1 408 changes the swing amplitude of traction rod 1 307, thereby controlling the swing angle of sector gear 405. Ultimately, the range of elevation of atomizing nozzle 8 can be flexibly adjusted to meet the space height requirements of different wards. The compound motion of the lifting mechanism 7: The large pitch design of screw rod 2 702 allows screw block 2 703 to move a greater distance in a single lift, quickly covering a wider range of heights. At the same time, the cooperation between the blocking block 713 and the trapezoidal pressure block 712 causes the atomizing nozzle 8 to swing horizontally during the lifting process, compensating for the blind spots of spraying during simple up and down movement, ensuring air purification without blind spots. Improved disinfection efficiency: The stirring mechanism 2 ensures uniform mixing of the disinfectant and virus-laden waste air. The atomizing pump 5 sprays the purified air through the atomizing nozzle 8, significantly increasing the contact area with the air and broadening the purification range. The synergistic effect of the lifting mechanism 7 and the swing mechanism expands the spray coverage area.
