[0020] The simple airtightness inspection device of the utility model is described in detail below through the accompanying drawings and embodiments.

[0021] This embodiment discloses a simple airtightness inspection device, such as Figure 1 As shown, it includes a bracket 1 and a hood 2; the hood 2 is hung on the bracket 1 through a hanging rod 3; in the disclosed embodiment, the bracket 1 adopts a carbon fiber tube with an outer diameter of 25mm; the size is about 3600*1150*2160mm; the hood 2 is made of stainless steel.

[0022] In this embodiment, the head cover 2 is provided with a control unit and a spreading unit; the control unit includes a control module 5, a power supply module 4, a voice broadcast module 10, an alarm module and a monitoring module 11; the power supply module 4, the voice broadcast module 10, the alarm module and the monitoring module 11 are all electrically connected to the aforementioned control module 5; the spreading unit includes a reagent bottle 8; a spray atomization device is provided at the bottle mouth of the reagent bottle 8; the spray atomization device is electrically connected to the aforementioned control module 5; in this embodiment, the spray atomization device converts the liquid inspection agent into an aerosol state through high-frequency vibration of the atomization plate, thereby achieving an atomization effect.

[0023] The aforementioned spray atomization device, voice broadcast module 10, alarm module and monitoring module 11 are all arranged in the aforementioned hood 2. In the disclosed embodiment, the control module 5 adopts an MCU module; the monitoring module 11 adopts an infrared human body sensor; and the alarm module adopts an alarm indicator 9. The MCU module is mainly used to control each module; the monitoring module 11 mainly monitors whether a person enters the hood 2. When a person enters / leaves the hood 2, the monitoring module 11 feeds back the electrical signal of the person entering / leaving to the MCU module; the alarm module is used to prompt the monitoring status of the person. The same as the indoor inspection, when the person wearing the mask to be detected does not stay in the hood 2 for the required time, the alarm indicator 9 alarms; the voice broadcast module 10 is used to broadcast the monitoring status of the person in real time. When the person does not stay in the hood 2 for the required time, the voice prompt "test failed"; when the person stays for the required time, the voice prompt "test passed, please leave" is given.

[0024] In the disclosed embodiment, six hoods 2 are arranged on the support 1. The height of the hood 2 is set according to the height of the person, and there are four heights of S, M, L, and XL. The S height is suitable for people with a height of 160-170cm, the M height is suitable for people with a height of 170-175cm, the L height is suitable for people with a height of 175-180cm, and the XL height is suitable for people with a height of 180-185cm. Among them, two hoods 2 of M and L heights are set, and one hood 2 of S and XL heights is set. By setting six hoods 2 on the support 1, multiple air tightness inspections can be carried out simultaneously, which can significantly improve the inspection efficiency. A transparent enclosure is arranged on the periphery of the hood 2. In this embodiment, the enclosure selects a transparent waterproof soft film, and the external supervisor can directly see the state of the person entering the hood 2. By setting the enclosure, a relatively closed space inside the hood 2 can be guaranteed to achieve the inspection agent concentration required for the air tightness inspection.

The charging interface 6 and the power indicator light 7 are both electrically connected to the aforementioned power supply module 4. By providing the charging interface 6 and the power indicator light 7, a charging operation is provided for the power supply module, reducing the dependence of the airtightness inspection device on the wired power supply, further improving the simplicity of the airtightness inspection device, and improving the convenience of outdoor airtightness inspection.

[0026] When conducting an airtightness inspection, the person wears the mask to be inspected and enters the hood 2. When the person enters the hood 2, the infrared human body sensor detects the person's position information, and then feeds back the electrical signal to the MCU module. After receiving the person's entry signal, the MCU module issues a command to start the spraying system, and the inspection agent is sprayed from the spraying atomization device at the outlet of the reagent bottle 8 to reach a certain reagent concentration in the hood 2. If within the specified time, the person is stimulated by the airtightness inspection agent and leaves the hood 2, it means that the person has not put on the mask properly, the alarm indicator light 9 alarms, and the voice broadcast module 10 voice prompts "test failed". When the person reaches the specified time in the hood 2, it means that the person wears the mask well, the voice broadcast module 10 voice prompts "test passed, please leave", and the spraying atomization device is turned off.
