Description

Technical Field

[0001] The present invention relates to the technical field of spraying equipment, and particularly relates to an automatic disinfectant spraying equipment. Background Art

[0002] Medical disinfectant spraying equipment refers to equipment specifically designed to evenly and precisely spray disinfectants onto target areas in medical scenarios according to specific requirements to achieve the purpose of disinfection and sterilization, ensuring the safety of the medical environment and the health of personnel. The hydrogen peroxide dry fog disinfection device is one of the disinfectant spraying equipment. The hydrogen peroxide dry fog disinfector is a device that uses dry fog technology to convert hydrogen peroxide into tiny particles for disinfection.

[0003] Currently, the following technical problems are found in the existing automatic disinfectant spraying equipment:

[0004] First, in the previous hydrogen peroxide dry fog disinfection device, its atomizing nozzle is usually fixed at a certain position, with a fixed spraying angle and limited coverage. In places such as hospitals with complex spatial layouts and large areas, such as ward buildings and outpatient halls, it is difficult to achieve full - coverage and dead - angle - free disinfection. If the entire area needs to be comprehensively disinfected, staff need to frequently move the equipment, which is a cumbersome and inefficient operation process. Moreover, during the process of moving the equipment, some areas may be missed, unable to ensure the comprehensiveness of disinfection. For example, when disinfecting the corridors in large hospitals, the fixed - angle nozzles cannot simultaneously cover the walls and floors on both sides of the corridor, resulting in poor disinfection effects.

[0005] Second, in some special areas of hospitals, such as enclosed laboratories and basements, the air flow is poor. When the traditional hydrogen peroxide dry fog disinfection device is used in these places, the sprayed disinfectant dry fog is difficult to fully diffuse, easily accumulates in local areas, and some areas cannot be reached, forming disinfection blind spots, which makes it difficult to ensure the disinfection effect in these places and poses a greater health and safety hazard. For example, in the microbiology laboratory of a hospital, if the disinfection is not thorough, the remaining microorganisms may interfere with the experimental results and even cause cross - infection.

[0006] Third, in most of the existing hydrogen peroxide dry fog disinfection devices, there is a lack of an effective solution stirring device. When using disinfectants such as hydrogen peroxide, due to insufficient stirring of the solution, the solution concentration is uneven. When the part with too high a concentration enters the atomizing nozzle, it is easy to cause nozzle blockage, reducing the spraying amount or even unable to spray, and too low a concentration will greatly reduce the disinfection effect. Summary of the Invention

[0007] In order to solve the above - mentioned technical problems, the present invention provides an automatic disinfectant spraying equipment to solve the above problems.

[0008] An automatic disinfectant spraying device, comprising a disinfector body, a disinfectant liquid bucket is provided on the disinfector body, a rotating shaft is rotatably installed through the disinfectant liquid bucket, stirring blades are provided on the rotating shaft, a circular support column is fixedly installed on the disinfector body, a ventilation duct is provided on the circular support column, an atomizing nozzle is fixedly installed through the ventilation duct, an air inlet channel is provided at the lower end of the atomizing nozzle, a solution channel is provided on the air inlet channel, a fixed bracket is fixedly installed on the ventilation duct, a lever is provided on the fixed bracket, a strengthening fan is fixedly installed at the right end of the lever, a rectifying sleeve is fixedly installed at the left end of the lever, a filter mesh plate for filtering dust is provided between the ventilation duct and the strengthening fan, a second spur gear is fixedly installed through the circumferential surface of the rotating shaft, a first spur gear is fixedly installed through the circumferential surface of the atomizing nozzle, and a gear synchronous belt is engaged between the second spur gear and the first spur gear.

[0009] Preferably, the number of the stirring blades is two, and both of the two stirring blades rotate inside the disinfectant liquid bucket. A motor bracket is fixedly installed at the upper end of the disinfector body, and a servo motor is fixedly installed on the motor bracket. The lower end of the servo motor is fixedly connected to the rotating shaft through an output shaft.

[0010] Preferably, a rotating ring column is rotatably installed on the circular support column through a sealing bearing. The rotating ring column is fixedly installed at the lower end of the ventilation duct. The atomizing nozzle and the air inlet channel are rotatably connected through a sealing bearing. The shape of the lever is Z-shaped, and the lever is rotatably installed on the fixed bracket through a rotating rod. A support plate is fixedly installed on the fixed bracket.

[0011] Preferably, a locking screw is installed through the support plate in a threaded manner. Two limit holes are opened on the side end of the lever. The locking screw is clamped with the limit holes opened on the lever. A circular through hole is opened in the rectifying sleeve and is communicated with the atomizing nozzle.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, when disinfecting precision instruments, etc., by clamping the rectifying sleeve at the port of the atomizing nozzle, the dry mist can naturally settle through its circular channel and gently adhere to the surface of the device, reducing the risk of physical damage to the device. While achieving effective disinfection, the damage to precision instruments is minimized to the greatest extent, ensuring the normal operation and service life of the instruments, and ensuring that medical testing and scientific research work are not affected.

[0014] In the present invention, through the cooperation of the second spur gear, the first spur gear and the gear synchronous belt, when the servo motor drives the rotation of the rotating shaft, the rotating ring column and the ventilation duct can be rotated, realizing the 360-degree rotation of the fog outlet of the atomizing nozzle, so that the hydrogen peroxide dry fog can be sprayed more evenly in every corner of the hospital, improving the disinfection work efficiency. In this process, the atomizing nozzle can cover the disinfection area in all directions. The operator does not need to frequently adjust the position of the equipment during the disinfection process. Only by determining the position of the equipment during the initial setting, the nozzle can automatically rotate to complete the large-area disinfection task. Taking the ward area of the hospital as an example, one placement of the equipment can achieve effective disinfection of every corner of the ward, greatly improving the efficiency of the disinfection work and reducing the time and labor costs required for the disinfection operation.

[0015] In the present invention, in a place with poor air fluidity, by rotating the strengthening fan to the right end of the ventilation duct and turning it on, the dry fog of the disinfectant sprayed by the atomizing nozzle can be further diffused. The strengthening fan will supply air into the ventilation duct. Under the action of the wind force of the strengthening fan, the dry fog of the disinfectant sprayed by the atomizing nozzle will be further diffused around, which can promote the full mixing of the dry fog with the surrounding air, make the concentration distribution of hydrogen peroxide in the air more uniform, and ensure the consistency of the disinfection effect. For areas with ventilation dead corners where the dry fog is not easily reached naturally, the blowing of the strengthening fan can guide the dry fog into these areas, reducing the disinfection blind spots and enhancing the overall disinfection effect.

[0016] In the present invention, by arranging a filter screen plate between the ventilation duct and the strengthening fan, it can effectively prevent the strengthening fan from bringing the dust in the air into the interior of the ventilation duct. The filter screen plate is like a barrier that can intercept the dust, ensuring that the air entering the ventilation duct is relatively clean. This can not only maintain the normal operation of the atomizing nozzle, ensure the uniformity and stability of its spraying, but also reduce the situation of frequent cleaning or replacement of the nozzle due to nozzle blockage, reduce the equipment maintenance cost, extend the service life of the equipment, and improve the continuity and reliability of the disinfection work.

[0017] In the present invention, by providing a servo motor to drive the rotation of the rotating shaft, and then the stirring blades stir the hydrogen peroxide solution in the disinfectant solution barrel, it can promote the solution to enter the interior of the disinfection machine body more evenly, reduce the blockage or abnormal atomization of the atomizing nozzle, improve the atomization quality, and enhance the disinfection effect. The stirring blades of the present invention are designed to be two. Driven by the rotating shaft, a good stirring flow field can be formed in the disinfectant solution barrel, so that the hydrogen peroxide molecules in the solution are fully dispersed. Such a uniform solution can ensure stable pressure and smooth liquid flow in the nozzle after entering the atomization system, thereby generating fine and uniform dry fog particles. These high-quality dry fog particles have a longer suspension time and a wider diffusion range in the air, can contact with microorganisms more effectively, and significantly enhance the disinfection effect.

Detailed implementation manners

[0028] The following further describes the implementation manners of the present invention in detail in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0029] Please refer to Figure 1 - Figure 9, the present invention provides an automatic disinfectant spraying device, including a disinfector body 37. A disinfectant solution bucket 38 is provided on the disinfector body 37. A rotating shaft 33 is installed through the disinfectant solution bucket 38 in a rotating manner. Stirring blades 36 are provided on the rotating shaft 33. A circular support column 24 is fixedly installed on the disinfector body 37. A ventilation duct 11 is provided on the circular support column 24. An atomizing nozzle 23 is fixedly installed through the ventilation duct 11. An air intake passage 21 is provided at the lower end of the atomizing nozzle 23. A solution passage 22 is provided on the air intake passage 21. A fixed bracket 15 is fixedly installed on the ventilation duct 11. A lever 14 is provided on the fixed bracket 15. A strengthening fan 19 is fixedly installed at the right end of the lever 14. A rectifying sleeve 13 is fixedly installed at the left end of the lever 14. A filter mesh plate 16 for filtering dust is provided between the ventilation duct 11 and the strengthening fan 19. A second spur gear 35 is fixedly installed through the circumferential surface of the rotating shaft 33. A first spur gear 31 is fixedly installed through the circumferential surface of the atomizing nozzle 23. A gear synchronous belt 32 is engaged between the second spur gear 35 and the first spur gear 31. An appropriate amount of hydrogen peroxide solution with a required concentration, such as a solution with a concentration of 3% - 6% commonly seen, is added to the disinfectant solution bucket 38 to meet the requirements of different disinfection scenarios. Then, operations are carried out through the existing technology inside the disinfector body 37. The control system is turned on to preheat and self-check the device, and check whether each component is operating normally. When the device passes the self-check, the control system issues an instruction to start the liquid pump. The liquid pump transports the hydrogen peroxide solution in the disinfectant solution bucket 38 to the atomizing system through a pipeline. The high-speed air flow generated by the air pump inside the disinfector body 37 passes through the air intake passage 21 at the lower end of the atomizing nozzle 23. According to the Venturi effect, a negative pressure is formed inside the atomizing nozzle 23, and the hydrogen peroxide solution is sucked into the nozzle through the solution passage 22. The high-speed air flow and the solution meet in the mixing chamber of the atomizing nozzle 23, and the air flow cuts the solution into tiny droplets to form dry fog. The formed dry fog can be sprayed out through the atomizing nozzle 23, thereby disinfecting various places in the hospital.

[0030] The number of stirring blades 36 is two, and both of the two stirring blades 36 rotate inside the disinfectant solution barrel 38. A motor bracket 39 is fixedly installed at the upper end of the disinfectant machine body 37, and a servo motor 34 is fixedly installed on the motor bracket 39. The lower end of the servo motor 34 is fixedly connected to a rotating shaft 33 through an output shaft. When the hydrogen peroxide disinfectant in the disinfectant solution barrel 38 is in use, the servo motor 34 can be controlled to work, so that the servo motor 34 drives the rotating shaft 33 to rotate through the output shaft. At this time, the rotating shaft 33 drives the two groups of stirring blades 36 to rotate, and the two groups of stirring blades 36 will stir in the hydrogen peroxide disinfectant. The stirring prompts the hydrogen peroxide solution to enter the inside of the disinfectant machine body 37 in a more uniform state, reducing the blockage or abnormal atomization of the atomizing nozzle 23 caused by uneven solution. If there are areas with too high or too low local concentration in the solution, it may affect the pressure and liquid flow inside the nozzle. Stirring can make the liquid pass through the nozzle smoothly and steadily, improving the atomization quality. In the process of atomization of a uniform solution, it is easier to form small and uniform dry fog particles. These small and uniform fog droplets have better suspension and more uniform diffusion in the air, which can effectively increase the contact area with microorganisms and enhance the disinfection effect.

[0031] A rotating ring column 25 is rotatably installed on the circular support column 24 through a sealed bearing. The rotating ring column 25 is fixedly installed at the lower end of the ventilation duct 11. The atomizing nozzle 23 and the air inlet channel 21 are rotatably connected through a sealed bearing. The shape of the lever 14 is Z-shaped, and the lever 14 is rotatably installed on the fixed bracket 15 through a rotating rod. A support plate 18 is fixedly installed on the fixed bracket 15. While the servo motor 34 is working to drive the rotating shaft 33 to rotate, it will drive the second spur gear 35 to rotate. At this time, the second spur gear 35 and the first spur gear 31 are connected through a gear synchronous belt 32. Therefore, the rotation of the second spur gear 35 will drive the first spur gear 31 to rotate through the gear synchronous belt 32. At this time, the first spur gear 31 will drive the rotating ring column 25 and the ventilation duct 11 to rotate. Since the atomizing nozzles 23 inside the rotating ring column 25 and the ventilation duct 11 are both installed in the circular support column 24 and the air inlet channel 21 through sealed bearings, the rotating ring column 25 and the ventilation duct 11 can both rotate. At this time, the fog outlet port of the atomizing nozzle 23 can rotate 360 degrees, so that the hydrogen peroxide dry fog can be sprayed more evenly in every corner of the hospital. There is no need to frequently move the disinfection equipment itself. Just rotating the atomizing nozzle 23 can change the spraying direction, which greatly saves the time and energy for adjusting the equipment position. In large-area disinfection work, the operator can complete a large-scale disinfection task by rotating the spray head at a fixed position, reducing the number of times the equipment is moved and improving the work efficiency.

[0032] A locking screw rod 17 is installed through the support plate 18 by means of threads. Two limit holes are provided at the side end of the lever 14. The locking screw rod 17 is clamped with the limit holes provided on the lever 14. A circular through-hole is provided in the rectifying sleeve 13 and is connected in communication with the atomizing nozzle 23. When disinfecting in some places with poor air fluidity, such as a closed laboratory or basement in a hospital, the user only needs to place the filter mesh plate 16 at the right end of the ventilation duct 11, and then rotate the locking screw rod 17. Through the threaded connection between the locking screw rod 17 and the support plate 18, the locking screw rod 17 is separated from the lever 14. Then, the lever 14 is rotated to rotate the booster fan 19 (the power source used by the booster fan 19 is an independent lithium battery, which is installed inside itself and will not be affected by the rotation of the ventilation duct 11) to the right end of the ventilation duct 11. At this time, the filter mesh plate 16 is clamped between the ventilation duct 11 and the booster fan 19. After the booster fan 19 is located at the side end of the ventilation duct 11, the rectifying sleeve 13 will be opened from the left end of the ventilation duct 11 to provide an open channel for the port of the ventilation duct 11. At this time, the booster fan 19 is controlled to start, and the booster fan 19 will supply air into the ventilation duct 11. Under the action of the wind force of the booster fan 19, the dry mist sprayed out by the atomizing nozzle 23 will be further diffused around, which can promote the full mixing of the dry mist with the surrounding air, make the concentration distribution of hydrogen peroxide in the air more uniform, and ensure the consistency of the disinfection effect. For areas with ventilation dead corners where the dry mist is not easily reached naturally, the booster fan 19 can blow to guide the dry mist into these areas, reduce the disinfection blind area, and improve the overall disinfection effect. When the booster fan 19 is not needed, the user can operate the locking screw rod 17 and the support plate 18 again, and then rotate the lever 14. At this time, the booster fan 19 will return to its original position and thus be separated from the ventilation duct 11. The filter mesh plate 16 located between the ventilation duct 11 and the booster fan 19 can be removed for cleaning. The filter mesh plate 16 can prevent the booster fan 19 from bringing dust in the air into the ventilation duct 11 and avoid the dust from clogging the atomizing nozzle 23. When the booster fan 19 returns to its original position, the rectifying sleeve 13 will be clamped at the port of the atomizing nozzle 23. At this time, a circular channel will be formed at the fog outlet of the atomizing nozzle 23. When disinfecting the surfaces of some precision instruments and electronic devices, the dry mist can pass through the circular channel of the rectifying sleeve 13, and the natural settlement can more gently adhere to the device surface, avoiding the impact of the dry mist particles on the device due to the air flow and reducing the risk of physical damage to the device. For example, when disinfecting precision instruments such as nuclear magnetic resonance instruments and electron microscopes, the dry mist of natural settlement can complete the disinfection without affecting the performance of the device.

[0033] Working principle: When the device performs disinfection work in a hospital, the following steps are required for operation.

[0034] First step, add an appropriate amount of hydrogen peroxide solution with a required concentration into the disinfectant solution bucket 38, such as a solution with a common concentration of 3% - 6%, to meet the requirements of different disinfection scenarios. Then, operate through the existing technology inside the disinfection machine body 37. Turn on the control system, preheat and self-check the device, and check whether each component is operating normally. When the device passes the self-check, the control system issues an instruction to start the liquid pump. The liquid pump transports the hydrogen peroxide solution in the disinfectant solution bucket 38 to the atomization system through a pipeline. The high-speed air flow generated by the air pump inside the disinfection machine body 37 passes through the air intake channel 21 at the lower end of the atomization nozzle 23. According to the Venturi effect, a negative pressure is formed inside the atomization nozzle 23, and the hydrogen peroxide solution is inhaled into the nozzle through the solution channel 22. The high-speed air flow meets the solution in the mixing chamber of the atomization nozzle 23, and the air flow cuts the solution into tiny droplets, forming dry fog. The formed dry fog can be ejected through the atomization nozzle 23 to disinfect various places in the hospital.

[0035] Second step, when using the hydrogen peroxide disinfectant in the disinfectant solution bucket 38, the servo motor 34 can be controlled to operate, so that the servo motor 34 drives the rotating shaft 33 to rotate through the output shaft. At this time, the rotating shaft 33 drives the two groups of stirring blades 36 to rotate, and the two groups of stirring blades 36 will stir in the hydrogen peroxide disinfectant. Stirring promotes the hydrogen peroxide solution to enter the inside of the disinfection machine body 37 in a more uniform state, reducing the blockage or abnormal atomization of the atomization nozzle 23 caused by uneven solution. If there are areas with too high or too low local concentration in the solution, it may affect the pressure and liquid flow inside the nozzle. Stirring can make the liquid pass through the nozzle smoothly and stably, improving the atomization quality. In the process of atomizing the uniform solution, it is easier to form fine and uniform dry fog particles. These fine and uniform fog droplets have better suspension and more uniform diffusion in the air, can effectively increase the contact area with microorganisms, and enhance the disinfection effect.

[0036] In the third step, while the servo motor 34 is working to drive the rotation of the rotating shaft 33, it will drive the rotation of the second spur gear 35. At this time, the second spur gear 35 and the first spur gear 31 are connected by a gear synchronous belt 32. Therefore, the rotation of the second spur gear 35 will drive the rotation of the first spur gear 31 through the gear synchronous belt 32. At this time, the first spur gear 31 will drive the rotation of the rotating ring column 25 and the ventilation duct 11. Since the atomizing nozzles 23 inside the rotating ring column 25 and the ventilation duct 11 are installed in the circular support column 24 and the air inlet passage 21 through sealed bearings, both the rotating ring column 25 and the ventilation duct 11 can rotate. At this time, the mist outlet ports of the atomizing nozzles 23 can rotate 360 degrees, so that the hydrogen peroxide dry mist can be sprayed more evenly in every corner of the hospital. There is no need to frequently move the disinfection equipment itself. Just rotating the atomizing nozzle 23 can change the spraying direction, greatly saving the time and effort of adjusting the equipment position. In large-area disinfection work, the operator can complete the disinfection task in a larger range by rotating the spray head at a fixed position, reducing the number of times the equipment moves and improving the work efficiency.

[0037] In the fourth step, when disinfecting in some places with poor air fluidity, such as enclosed laboratories and basements in hospitals, the user only needs to place the filter mesh plate 16 at the right end of the ventilation duct 11, and then rotate the locking screw 17. Through the threaded connection between the locking screw 17 and the support plate 18, the locking screw 17 is separated from the pry bar 14. Since the shape of the pry bar 14 is Z-shaped, when the pry bar 14 rotates, the enhanced fan 19 (the power source used by the enhanced fan 19 is an independent lithium battery installed inside itself and will not be affected by the rotation of the ventilation duct 11) can be rotated to the right end of the ventilation duct 11, and the rectifying sleeve 13 is lifted up so that the rectifying sleeve 13 will not affect the enhancement of the spray by the enhanced fan 19. At this time, the filter mesh plate 16 is clamped between the ventilation duct 11 and the enhanced fan 19. After the enhanced fan 19 is located at the side end of the ventilation duct 11, the rectifying sleeve 13 will open from the left end of the ventilation duct 11 to provide an open channel for the port of the ventilation duct 11. At this time, the enhanced fan 19 is controlled to start, and the enhanced fan 19 will supply air into the ventilation duct 11. Under the action of the wind force of the enhanced fan 19, the disinfectant dry mist sprayed by the atomizing nozzles 23 will be further diffused to the surrounding, which can promote the full mixing of the dry mist with the surrounding air, make the concentration distribution of hydrogen peroxide in the air more uniform, and ensure the consistency of the disinfection effect. For areas with ventilation dead ends where the dry mist is not easily reached naturally, the enhanced fan 19 can blow to guide the dry mist into these areas, reducing the disinfection blind spots and improving the overall disinfection effect.

[0038] In the fifth step, when the enhanced fan 19 is not needed, the user can operate the locking screw 17 and the support plate 18 again, and then rotate the lever 14. At this time, the enhanced fan 19 will return to its original position, thus separating from the ventilation duct 11. The filter screen plate 16 located between the ventilation duct 11 and the enhanced fan 19 can be removed for cleaning. The filter screen plate 16 can prevent the enhanced fan 19 from bringing dust in the air into the interior of the ventilation duct 11 and avoid clogging the atomizing nozzle 23 with dust. When the enhanced fan 19 returns to its original position, the rectifying sleeve 13 will be clamped at the port of the atomizing nozzle 23. At this time, a circular channel will be formed at the fog outlet port of the atomizing nozzle 23. When disinfecting the surfaces of some precision instruments and electronic devices, the dry fog can pass through the circular channel of the rectifying sleeve 13, and the natural sedimentation can more gently adhere to the device surface, avoiding the impact of dry fog particles on the device due to air flow and reducing the risk of physical damage to the device. For example, when disinfecting precision instruments such as nuclear magnetic resonance spectrometers and electron microscopes, the naturally sedimented dry fog can complete the disinfection without affecting the performance of the device.

[0039] In the present invention, a servo motor 34 is provided to drive the rotation of a rotating shaft 33, thereby causing the stirring blades 36 to stir the hydrogen peroxide solution in the disinfectant solution barrel 38, which can promote the solution to enter the interior of the disinfection machine body 37 more evenly, reduce the blockage or abnormal atomization of the atomizing nozzles 23, improve the atomization quality, and enhance the disinfection effect. The stirring blades 36 of the present invention are designed to be two. Driven by the rotating shaft 33, a good stirring flow field can be formed in the disinfectant solution barrel 38, enabling the hydrogen peroxide molecules in the solution to be fully dispersed. After such a uniform solution enters the atomization system, it can ensure stable pressure inside the nozzle and smooth liquid flow, thereby generating fine and uniform dry fog particles. These high-quality dry fogs can suspend in the air for a longer time and have a wider diffusion range, can come into contact with microorganisms more effectively, and significantly enhance the disinfection effect. In the present invention, through the cooperation of the second spur gear 35, the first spur gear 31, and the gear synchronous belt 32, when the servo motor 34 drives the rotation of the rotating shaft 33, the rotating ring column 25 and the ventilation duct 11 can be rotated, realizing a 360-degree rotation of the mist outlet of the atomizing nozzle 23, making the hydrogen peroxide dry fog spray more evenly in all corners of the hospital, improving the disinfection work efficiency. During this process, the atomizing nozzle 23 can cover the disinfection area in all directions. The operator does not need to frequently adjust the position of the equipment during the disinfection process. Only by determining the position of the equipment during the initial setting, the nozzle can automatically rotate to complete the large-area disinfection task. Taking the ward area of the hospital as an example, one placement of the equipment can achieve effective disinfection of all corners of the ward, greatly improving the efficiency of the disinfection work and reducing the time and labor costs required for the disinfection operation. In the present invention, in places with poor air fluidity, by rotating the strengthening fan 19 to the right end of the ventilation duct 11 and turning it on, the disinfectant dry fog sprayed by the atomizing nozzle 23 can be further diffused. The strengthening fan 19 will supply air into the ventilation duct 11. Under the action of the wind force of the strengthening fan 19, the disinfectant dry fog sprayed by the atomizing nozzle 23 will be further diffused around, which can promote the full mixing of the dry fog with the surrounding air, make the concentration distribution of hydrogen peroxide in the air more uniform, and ensure the consistency of the disinfection effect. For areas with ventilation dead ends where the dry fog is not easily reached naturally, the blowing of the strengthening fan 19 can guide the dry fog into these areas, reducing the disinfection blind spots and enhancing the overall disinfection effect. In the present invention, by providing a filter plate 16 between the ventilation duct 11 and the strengthening fan 19, it can effectively prevent the strengthening fan 19 from bringing dust in the air into the interior of the ventilation duct 11. The filter plate 16 is like a barrier that can intercept dust, ensuring that the air entering the ventilation duct 11 is relatively clean. This can not only maintain the normal operation of the atomizing nozzle 23, ensure the uniformity and stability of its spraying, but also reduce the situation of frequent cleaning or replacement of the nozzle due to nozzle blockage, reduce the equipment maintenance cost, extend the service life of the equipment, and improve the continuity and reliability of the disinfection work. In the present invention, when disinfecting precision instruments, etc., by clamping the rectifying sleeve 13 at the port of the atomizing nozzle 23, the dry fog can naturally settle through its circular channel.Gently adhere to the surface of the device, reducing the risk of physical damage to the device. While achieving effective disinfection, it minimizes the damage to precision instruments, safeguards the normal operation and service life of the instruments, and ensures that medical testing and scientific research work are not affected.
