The right side of the exhaust pipe 10 passes through to the right side of the placement box 11.

[0027] A control terminal 12 is fixedly connected to the left side of the classified storage cabinet 1. A hazardous gas detector 9 is fixedly connected to the middle of the top of the inner wall of the classified storage cabinet 1. The hazardous gas purifier 8 is a photocatalytic exhaust gas purifier that is currently available on the market. It uses the principle of photocatalytic oxidation to purify hazardous gases. The hazardous gas detector 9 can detect combustible gases such as methane and propane, toxic and harmful gases such as carbon monoxide, hydrogen sulfide, and ammonia, as well as oxygen concentration. It detects gas concentration through an electrochemical sensor.

[0028] refer to Figure 1 The control terminal 12 has a heat dissipation hole 13 on its left side, and the heat dissipation hole 13 is elongated.

[0029] As a technical optimization of this utility model, by providing heat dissipation holes 13, the control terminal 12 can be cooled to prevent it from being damaged due to overheating.

[0030] refer to Figure 1 The bottom of the classified temporary storage cabinet 1 is fixedly connected with an anti-slip block 14.

[0031] As a technical optimization of this utility model, by setting the anti-slip block 14, the friction between the classification temporary storage cabinet 1 and the ground can be increased, making the classification temporary storage cabinet 1 more stable.

[0032] refer to Figure 2 A dust filter 15 is fixedly connected to the inner wall of the box 11 and to the left side of the air intake fan 2.

[0033] As a technical optimization of this utility model, by setting a dust filter 15, dust can be filtered to prevent dust from entering the intake fan 2.

[0034] refer to Figure 4 An activated carbon filter 16 is fixedly connected to the inner wall of the air outlet pipe 10.

[0035] As a technical optimization of this utility model, by setting an activated carbon filter 16, harmful substances in the gas can be adsorbed, which makes it convenient for users to use.

[0036] refer to Figure 1 The placement box 11 is made of aluminum alloy.

[0037] As a technical optimization of this utility model, by setting an aluminum alloy placement box 11, the strength of the placement box 11 can be increased, making the placement box 11 less prone to damage.

[0038] refer to Figure 2 Both the first branch pipe 3 and the second branch pipe 6 are made of stainless steel.

[0039] As a technical optimization of this utility model, by setting up the first diversion pipe 3 and the second diversion pipe 6 made of stainless steel, it is possible to prevent the first diversion pipe 3 and the second diversion pipe 6 from rusting and to prevent the first diversion pipe 3 and the second diversion pipe 6 from being damaged due to rusting.

[0040] The working principle and usage process of this utility model are as follows: First, the harmful gas detector 9 detects the harmful gas in the classified storage cabinet 1. The detection data is transmitted to the control terminal 12. The control terminal 12 analyzes and judges the detection data. When harmful gas is detected, the control terminal 12 starts the intake fan 2 and the exhaust fan 5, and opens the intake solenoid valve 4 and the exhaust solenoid valve 7. Fresh air is discharged from the output end of the intake fan 2 and delivered into the classified storage cabinet 1 through the first diversion pipe 3. At the same time, the input end of the exhaust fan 5 generates suction, which absorbs the harmful gas in the classified storage cabinet 1 through the second diversion pipe 6, causing the harmful gas to be discharged from the output end of the exhaust fan 5 and enter the harmful gas purifier 8. The harmful gas purifier 8 purifies the harmful gas, and finally, the purified harmful gas is discharged through the exhaust pipe 10. At this time, ventilation can be performed, thus achieving the effect of automatic ventilation.

[0041] In summary, this laboratory hazardous waste sorting and temporary storage cabinet, by incorporating a sorting and temporary storage cabinet 1, an intake fan 2, a first diversion pipe 3, an intake solenoid valve 4, an exhaust fan 5, a second diversion pipe 6, an exhaust solenoid valve 7, a hazardous gas purifier 8, a hazardous gas detector 9, an exhaust pipe 10, a storage box 11, and a control terminal 12, solves the problem that traditional sorting and temporary storage cabinets lack ventilation structures, leading to the accumulation of toxic and harmful gases emitted by hazardous waste during storage, which significantly increases the risk of explosion or poisoning due to the large accumulation of these gases within the cabinet.
