Description

Technical Field

[0001] This utility model relates to the field of disinfection device technology, and in particular to an atomizing environmental disinfection device. Background Technology

[0002] As is well known, for large-scale outdoor disinfection operations, due to the wide treatment area and open space, the disinfection equipment is usually required to have the characteristics of large coverage area and long range. Based on the Venturi principle, jet atomizing disinfection equipment has become a common choice in such scenarios due to its large air volume and long-range delivery capability.

[0003] Chinese patent CN220308185U describes a spray disinfection device, comprising a housing, a movable base, a movable tube, a first power mechanism, a second power mechanism, and an atomizing device. The second power mechanism drives the movable base to swing left and right, thereby changing the direction of the movable tube opening and saving manpower. However, in practical use, the following problems still exist:

[0004] In traditional jet-type structures, the high-speed airflow shears and breaks down the liquid pesticide during atomization, resulting in randomness and instability. This directly leads to a wide droplet spectrum and an excessively large droplet size distribution. The droplet cluster contains a large number of large-diameter droplets. Due to their large mass and inertia, these large-diameter droplets cannot effectively follow the airflow after leaving the nozzle. Under the influence of gravity, they quickly settle to local areas on the ground and cannot remain suspended for a long time to diffuse throughout the target space. This results in a short suspension time and uneven dispersion of the pesticide in the space, which reduces the disinfection coverage efficiency and affects the final disinfection effect.

[0005] Therefore, a misting-type environmental disinfection device is proposed. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a misting environmental disinfection device.

[0007] To achieve the aforementioned objective, this utility model adopts the following technical solution:

[0008] A misting-type environmental disinfection device includes a high-speed fan, on which an adaptive pulse-enhanced jet atomization disinfection device is mounted. The adaptive pulse-enhanced jet atomization disinfection device includes a Venturi atomizing tube, a spray tube, a drug inlet tube, a drug supply tank, a flexible hose, a pulse assembly, an enhancement assembly, and an angle-adaptive nozzle scaling assembly. One end of the Venturi atomizing tube is connected to the air outlet of the high-speed fan, and the other end of the Venturi atomizing tube is fixedly connected to one end of the spray tube. The other end of the spray tube is connected to the angle-adaptive nozzle scaling assembly. The movable end of the caliber-adaptive scaling component is connected to the fixed end of the caliber-adaptive scaling component, which is connected to the outer wall of the injection tube. The bottom end of the drug inlet tube is connected to the throat of the Venturi atomizing tube, and the top end of the drug inlet tube is connected to the bottom end of the pulse component. The top end of the pulse component is connected to one end of the hose, and the other end of the hose is connected to the drug supply box. The reinforcing component is located between the pulse component and the Venturi atomizing tube and is connected to the outer wall of the drug inlet tube.

[0009] The pulse assembly includes a connecting tube and elastic valves. The bottom end of the connecting tube is connected to the top end of the drug inlet tube, and the top end of the connecting tube is connected to the flexible tube. Several elastic valves are provided. The elastic valves are uniformly fixedly connected to the inner wall of the connecting tube along the axis of the connecting tube, and the elastic valves together form an inverted conical structure.

[0010] The bottom end of the connecting tube is provided with an internal thread, the top end of the drug inlet tube is provided with an external thread, and the connecting tube is threadedly connected to the drug inlet tube. A limiting ring is provided inside the drug inlet tube, the outer wall of the limiting ring is fixedly connected to the inner wall of the drug inlet tube, and the inner wall of the limiting ring is in contact with the elastic valve.

[0011] The reinforcing component includes a pressure tube, a sealing cap, a piston, and a first spring. One end of the pressure tube is connected to the side wall of the drug inlet tube, and the other end of the pressure tube is connected to the sealing cap. The piston is located inside the pressure tube and is slidably connected to the inner wall of the pressure tube. The first spring is located inside the pressure tube, and the side of the piston away from the drug inlet tube is fixedly connected to the sealing cap through the first spring. The sealing cap is provided with a connecting hole for balancing air pressure.

[0012] The angle-adaptive aperture scaling assembly includes a fixed ring, a gravity sliding ring, a second spring, a fan-shaped baffle plate, and a pusher. The inner wall of the fixed ring is fixedly connected to the outer wall of the injection tube. Several fan-shaped baffle plates are provided and are evenly distributed circumferentially along the axis of the injection tube. The fan-shaped baffle plates are hinged to the inner wall of the injection tube at the end away from the Venturi atomizing tube by pins. The gravity sliding ring is located between the fixed ring and the fan-shaped baffle plates and is axially slidably connected to the outer wall of the injection tube by a sliding member. The second spring is sleeved on the outside of the injection tube. One end of the second spring is fixedly connected to the side of the gravity sliding ring away from the fan-shaped baffle plate, and the other end of the second spring is fixedly connected to the side of the fixed ring adjacent to the fan-shaped baffle plate. The fixed end of the pusher is connected to the gravity sliding ring, and the movable end of the pusher is connected to the surface of the fan-shaped baffle plate.

[0013] The pushing component includes a pushing rod and a connecting rod. One end of the pushing rod is fixedly connected to the side of the gravity sliding ring adjacent to the sector-shaped blocking plate. The other end of the pushing rod is hinged to one end of the connecting rod via a pin. The other end of the connecting rod is hinged to the surface of the sector-shaped blocking plate via a pin.

[0014] The fan-shaped baffle is inclined relative to the axis of the jet pipe.

[0015] Compared with existing technologies, this invention has the following advantages: By periodically opening and closing the elastic valve under the negative pressure of the Venturi tube, the continuous liquid flow from the drug supply tank is converted into an intermittent pulse jet, which initially cavitates the drug solution. This avoids the problem of excessively wide droplet size distribution and a high proportion of large droplets caused by the high randomness of continuous liquid column breakage in traditional jet atomization, thus improving the atomization effect and ensuring the coverage of disinfection. Through the cooperation of the piston and the first spring, the piston generates a suction effect and pressure disturbance, which improves the cavitation effect of the drug solution before entering the Venturi atomizing tube, thereby further refining the droplet size and improving the atomization effect to ensure the coverage of disinfection. By adjusting the angle of the gravity sliding ring and the second spring sensing device, and by adjusting the opening and closing degree of the fan-shaped baffle plate with the push rod and connecting rod, the reduced coverage caused by the insufficient adaptability of the fixed-diameter nozzle in different application scenarios is avoided, thus improving the adaptability of the device and ensuring the coverage of disinfection.

The inner wall of the fixed ring 15 is fixedly connected to the outer wall of the injection pipe 3. Several fan-shaped baffle plates 18 are provided and are evenly distributed circumferentially along the axis of the injection pipe 3. The fan-shaped baffle plates 18 are hinged to the inner wall of the injection pipe 3 at the end away from the Venturi atomizing tube 2 by a pin. The gravity sliding ring 16 is located between the fixed ring 15 and the fan-shaped baffle plate 18, and the gravity sliding ring 16 is axially slidably connected to the outer wall of the injection pipe 3 by a sliding member.

[0032] like Figure 6 and Figure 8 As shown, the pusher includes a push rod 19 and a connecting rod 20.

The other end of the push rod 19 is hinged to one end of the connecting rod 20 through a pin.

[0033] like Figure 6 As shown, the fan-shaped baffle 18 is inclined relative to the axis of the jet pipe 3.

[0034] The work process is as follows:

[0035] S1. In use, pour the disinfectant solution into the supply tank 5, start the high-speed fan 1, and the high-speed airflow generated by the high-speed fan 1 enters the Venturi atomizing tube 2. When the high-speed airflow passes through the throat of the Venturi atomizing tube 2, it accelerates again, forming a significant negative pressure. Since the inlet tube 4 is connected to the throat of the Venturi atomizing tube 2, this negative pressure is transmitted to the inlet tube 4, causing a pressure difference between the liquid pressure in the connecting tube 7 and the negative pressure in the inlet tube 4. When the pressure difference is sufficient to overcome the elastic force of the elastic valve 8, the liquid solution opens the elastic valve 8 and is sprayed into the inlet tube 4 in the form of a jet. After the jet enters, it temporarily fills the negative pressure area, reducing the pressure difference between the inside and outside of the elastic valve 8. The elastic valve 8 quickly rebounds and closes due to its own elasticity. Subsequently, the pressure difference at the throat of the Venturi atomizing tube 2... Negative pressure is established again in the drug inlet tube 4, increasing the pressure difference and opening the elastic valve 8 again. During this process, the liquid drug enters the Venturi atomizing tube 2 in an intermittent pulse form. This process discretizes the continuous liquid drug into a jet, achieving preliminary cavitation before entering the Venturi atomizing tube 2. The liquid drug is then impacted and torn into fine mist by high-speed airflow in the Venturi atomizing tube 2, and finally sprayed out through the spray tube 3 to complete the disinfection. Through the periodic opening and closing of the elastic valve 8 under the negative pressure of the Venturi, the continuous liquid flow from the drug supply tank 5 is converted into an intermittent pulse jet, which performs preliminary cavitation on the liquid drug. This avoids the problem of excessively wide droplet size distribution and a high proportion of large droplets caused by the high randomness of continuous liquid column breakage in traditional jet atomization, thus improving the atomization effect and ensuring the coverage of disinfection.

[0036] S2, during the atomization process, when the elastic valve 8 is closed, the continuous negative pressure in the drug inlet tube 4 acts on the piston 12 in the pressure tube 10. Since the sealing cap 11 has a connecting hole 14 that communicates with the outside atmosphere, the piston 12 slides along the pressure tube 10 towards the drug inlet tube 4 under the combined action of atmospheric pressure and negative pressure, stretching the first spring 13 and storing elastic potential energy. At the moment when the elastic valve 8 is opened, the liquid medicine rushes into the drug inlet tube 4 from the connecting tube 7, and the pressure on the negative pressure side of the piston 12 rises rapidly. The first spring 13 releases elastic potential energy, driving the piston 12 to slide along the pressure tube 10 away from the drug inlet tube 4. This movement of the piston 12 generates a suction effect in the drug inlet tube 4, forming a pressure disturbance, which further enhances the cavitation effect of the liquid. Through the cooperation of the piston 12 and the first spring 13, the piston 12 generates a suction effect and pressure disturbance, which improves the cavitation effect of the liquid before it enters the Venturi atomizing tube 2, thereby further refining the droplet size, improving the atomization effect and ensuring the coverage of the disinfection.

[0037] S3, during the spraying process, the angle-adaptive nozzle scaling component automatically adjusts the spray mode according to the device's posture. When the device is at a horizontal or downward angle, the elastic force of the second spring 17 pushes the gravity sliding ring 16 closer to the fan-shaped baffle plate 18. The gravity sliding ring 16 pushes the fan-shaped baffle plate 18 through the push rod 19 and connecting rod 20, causing the fan-shaped baffle plate 18 to retract inward around the hinge point with the spray pipe 3, reducing the spray nozzle diameter. The smaller diameter increases the diffusion angle of the droplets, forming a fan-shaped mist field with a wide coverage area and a short range, suitable for diffuse disinfection in large spaces. When the device is lifted towards the air, the gravity sliding ring 16, under its own weight... Under the action of the second spring 17, it overcomes the elastic force and slides downward along the outer wall of the spray pipe 3. It also pulls the fan-shaped baffle 18 outward through the push rod 19 and the connecting rod 20 to increase the spray diameter. The larger diameter makes the mist flow more concentrated, forming a columnar jet with a long range and concentrated coverage. It is suitable for disinfection of targets at high altitudes. The angle of the sensing device is sensed by the gravity sliding ring 16 and the second spring 17. The opening and closing degree of the fan-shaped baffle 18 is adjusted by the push rod 19 and the connecting rod 20. This avoids the reduction in coverage caused by the insufficient adaptability of the fixed diameter nozzle in different application scenarios, improves the adaptability of the device and ensures the coverage of disinfection.

[0038] In addition, the distance between the elastic valve 8 and the limiting ring 9 can be adjusted by the limiting ring 9 set on the inner wall of the drug inlet tube 4 and the connecting pipe 7 threadedly connected to the drug inlet tube 4, thereby controlling the maximum opening degree to adapt to disinfectants of different viscosities. The fan-shaped baffle 18 is set at an inclination relative to the axis of the spray tube 3, so that when the spray tube 3 is closed, it can guide the mist flow to form a spiral airflow, further improving the uniformity of the drug mist diffusion.
