Description

Technical Field

[0001] This utility model relates to the field of laboratory disinfection equipment, and in particular to a laboratory aerosol removal device. Background Technology

[0002] Currently, when laboratory nucleic acid testing is performed frequently and the concentration of positive nucleic acid is high, it is very easy to cause aerosol contamination in the laboratory due to improper operation, which can lead to inaccurate test results and misjudgment of test results.

[0003] Aerosols are also divided into large-particle aerosols and small-particle aerosols. Large-particle aerosols will settle on the laboratory table or floor due to gravity and other factors, and can be removed by wiping the table or floor with nucleic acid removal agents (spraying with a spray bottle or wiping with a cloth). However, a lot of small-particle aerosols are suspended in the air. When there is airflow in the laboratory, they move in the laboratory space, which is difficult to remove and tends to persist for a long time, leading to inaccurate laboratory tests. Utility Model Content

[0004] The purpose of this invention is to provide a laboratory aerosol removal device that can dynamically maintain the uniformity and activity of hydrogen peroxide disinfectant in the storage tank, effectively avoid concentration decay caused by static sedimentation, and continuously degrade nucleic acids while settling aerosols, thus improving the reliability of environmental disinfection. The device is also designed with automation to meet the needs of long-term continuous operation in laboratories.

[0005] This utility model is achieved through the following measures:

[0006] A laboratory aerosol removal device includes a humidifier body, characterized in that a solution stirring mechanism is provided inside the humidifier body, and the liquid storage tank of the humidifier body is filled with disinfectant.

[0007] Preferably, the top of the liquid storage tank is provided with a liquid injection port;

[0008] The solution stirring mechanism includes a circulating water pump located at the bottom of the storage tank. An annular circulation pipeline is provided above the circulating water pump and inside the storage tank. The annular circulation pipeline is connected to the circulating water pump through a vertical pipe.

[0009] The solution stirring mechanism also includes a stirring shaft horizontally disposed inside the liquid storage tank. One end of the stirring shaft is mounted on one side wall of the liquid storage tank via a mounting base, and the other end of the stirring shaft is mounted on the other side wall of the liquid storage tank via a mounting base, extending out of the liquid storage tank and connected to a drive motor.

[0010] The specific features of this utility model also include:

[0011] The annular circulation pipeline is provided with several liquid outlets, and the annular circulation pipeline is installed on the inner wall of the liquid storage tank by means of a snap fastener.

[0012] The stirring shaft is equipped with several stirring plates.

[0013] The drive motor is surrounded by a housing.

[0014] The disinfectant is a 3%-6% hydrogen peroxide disinfectant.

[0015] When in use, the prepared hydrogen peroxide disinfectant is injected into the storage tank, and the hydrogen peroxide disinfectant is converted into water mist by the humidifier and sprayed into the air. By increasing the humidity in the air, the aerosols are settled, and the nucleic acids are degraded at the same time.

[0016] During operation, the stirring shaft rotates slowly to mix the hydrogen peroxide disinfectant solution in the storage tank, while the solution is circulated by the circulating water pump. The two work together to prevent the disinfectant solution from separating due to settling and to ensure uniform concentration.

[0017] The beneficial effects of this invention are as follows: On the one hand, this device can dynamically maintain the uniformity and activity of hydrogen peroxide disinfectant in the storage tank, effectively avoiding concentration decay caused by static sedimentation. On the other hand, in conjunction with the humidification and atomization function, it can continuously degrade nucleic acids while settling aerosols, thereby improving the reliability of environmental disinfection. Moreover, the automated design is adapted to the long-term continuous operation requirements of the laboratory. Attached Figure Description
