Technical Field

[0001] The utility model relates to a disinfection device, in particular to a disinfection device for clean laboratory personnel entering and exiting, belonging to the technical field of disinfection devices. Background Art

[0002] Cleanrooms must eliminate contaminants such as particulate matter, harmful air, and bacteria from the air within a certain range. Temperature, cleanliness, pressure, airflow velocity and distribution, noise, vibration, lighting, and static electricity must all be controlled within a specified range. Cleanrooms are typically categorized based on the number of particles in the laboratory air. Within cleanroom areas, the behavior of inspectors has the greatest impact on product inspection, presenting the highest risk and being the most uncontrollable. Therefore, inspectors should adhere to good behavioral standards within cleanrooms. A key aspect of this is disinfection upon entry to minimize the introduction of bacteria into the laboratory.

[0003] Among the disinfection measures taken when entering the laboratory, the disinfection of hands is particularly important. The existing disinfection measures for laboratory personnel's hands are usually carried out by spraying and washing with disinfectant spray. However, this disinfection method easily causes the liquid mist to spread in the isolation and disinfection space, which may cause contamination in other locations and lead to secondary contamination of the laboratory personnel, thereby making the disinfection effect poor. Therefore, in order to solve the above problems, a clean laboratory personnel entry and exit disinfection device is proposed. Utility Model Content

[0009] The above-mentioned structural form provides the necessary structural basis for forming negative pressure in the sterilization area.

[0010] Furthermore, the disinfection spray spraying mechanism includes a water mist nozzle fixedly arranged on the upper partition, a main pipe fixedly connected to the box body is arranged directly above the water mist nozzle, and a branch pipe is sealed between the main pipe and the water mist nozzle.

[0011] In the above structure, the disinfectant pumped in from the outside is sent to the main pipe and then distributed to each water mist nozzle through the branch pipe. The disinfectant sprayed from the water mist nozzle will form a fine water mist, thereby improving the disinfection effect.

[0012] Furthermore, one end of the main pipe passes through the box body and is tightly connected to the end of the delivery pipe. The disinfectant supply box contains disinfectant and is equipped with a submersible pump. The first end of the delivery pipe is tightly connected to the output interface of the submersible pump.

[0013] The above structure can pump the disinfectant contained in the disinfectant supply box to the disinfectant spray ejection mechanism by a submersible pump.

[0014] Furthermore, the air duct includes a guide inclined plate and a return inclined plate fixedly connected to the box body, the guide inclined plate and the return inclined plate are parallel to each other, and three equidistantly arranged liquefaction plates are fixedly provided on the lower end surface of the guide inclined plate. A hole is opened on the side panel of the box body and a connecting pipe is fixedly provided therein, and the connecting pipe is tightly connected to the end of the air duct.

[0015] The above-mentioned structural form can use the guide inclined plate to guide the directly liquefied disinfectant into the liquid collection drawer, and can use the liquefaction plate to prevent the liquefaction of the liquid components in the air flow, and allow the liquefied disinfectant to flow along the reflux inclined plate to the liquid collection drawer for centralized treatment.

[0016] Furthermore, a handle is fixedly provided on the outer plate of the liquid collection drawer, and the liquid collection drawer can fit tightly with the side plate of the box body when it is fully pushed in.

[0017] The above structure can facilitate the experimenter to pull out the liquid collection drawer and process the waste liquid regularly.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] In the utility model, a disinfectant mist can be sprayed out through the disinfection spray spray mechanism to carry out disinfection. At the same time, the fan works to draw air to flow, and a negative pressure is formed in the disinfection area through the air duct and the air duct, which has the effect of absorbing and collecting the disinfectant mist, so that the disinfectant mist can be immediately sucked away after it comes into contact with the hands of the experimenter and completes the disinfection, avoiding its diffusion in the space used for isolation and disinfection, causing contamination in other locations and leading to secondary contamination of the experimenter. At the same time, most of the disinfectant will be collected by the liquid collection drawer for centralized treatment. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] like Figure 1 - Figure 2As shown, the present embodiment provides a clean laboratory personnel entry and exit disinfection device, including a hand disinfection box 1 and an external disinfectant supply box 2, a fan 3, the hand disinfection box 1 and the disinfectant supply box 2 are sealed by a delivery pipe 21, and the hand disinfection box 1 and the fan 3 are sealed by an air duct 31. The hand disinfection box 1 includes a box body 11, an upper partition 12 and a V-shaped ventilation partition 13 are fixedly provided in the box body 11, and a disinfection area 14 is enclosed between the upper partition 12 and the V-shaped ventilation partition 13. A disinfection spray spray mechanism 15 is installed on the upper partition 12, and a disinfection spray spray mechanism 15 is fixed to the box body 11 on the lower side of the V-shaped ventilation partition 13. The connected air duct 16 and the liquid collecting drawer 17 are slidingly provided at the bottom of the box body 11. The above-mentioned structural form can spray mist disinfectant through the disinfection spray spray mechanism 15 for disinfection. At the same time, the fan 3 works to draw the air flow, and forms a negative pressure in the disinfection area 14 through the air duct 31 and the air duct 16, which plays a role in adsorbing and collecting the mist disinfectant, so that the mist disinfectant can be immediately sucked away after contacting with the experimenter's hands to complete the disinfection, avoiding its diffusion in the isolation and disinfection space, causing contamination in other locations and leading to secondary contamination of the experimenter. At the same time, most of the disinfectant will be collected by the liquid collecting drawer 17 for centralized treatment.

[0028] like Figure 3 As shown, a plurality of air holes 131 distributed in an array are fixedly provided on the V-shaped ventilation partition 13 . The above-mentioned structural form provides the necessary structural basis for forming negative pressure in the disinfection area 14 .

[0029] like Figure 1 、 Figure 4 As shown, the disinfection spray spraying mechanism 15 includes a water mist nozzle 151 fixedly arranged on the upper partition 12, and a main pipe 152 fixedly connected to the box body 11 is arranged directly above the water mist nozzle 151, and a branch pipe 153 is sealed between the main pipe 152 and the water mist nozzle 151. In the above structural form, the disinfectant pumped in from the outside is sent to the main pipe 152, and then distributed to each water mist nozzle 151 through the branch pipe 153. The disinfectant sprayed from the water mist nozzle 151 will form a fine water mist, thereby improving the disinfection effect. At the same time, one end of the main pipe 152 passes through the box body 11 and is sealed with the end of the delivery pipe 21. The disinfectant supply box 2 contains disinfectant and is provided with a submersible pump. The head end of the delivery pipe 21 is sealed and connected to the output interface of the submersible pump. This structural form can use the submersible pump to pump the disinfectant contained in the disinfectant supply box 2 to the disinfection spray spraying mechanism 15.

The disinfectant sprayed from the water mist nozzle 151 will form a fine water mist for disinfection and improve the disinfection effect.

[0033] When the disinfection work is in progress, the fan 3 will work synchronously to draw air flow, forming a negative pressure in the disinfection area 14 through the air duct 31 and the air duct 16, which plays a role in absorbing and collecting the mist disinfectant, so that the mist disinfectant can be immediately sucked away after the disinfection is completed by contact with the experimenter's hands, avoiding its diffusion in the isolation and disinfection space, causing contamination in other locations and leading to secondary contamination of the experimenter. At the same time, most of the disinfectant will be collected by the liquid collection drawer 17 for centralized processing, and the directly liquefied disinfectant can be introduced into the liquid collection drawer 17 by the guide inclined plate 161, wherein the liquefaction plate 163 can play a role in preventing the liquefaction of the liquid component in the air flow, and the liquefied disinfectant can flow along the reflux inclined plate 162 to the liquid collection drawer 17.
