[0002] As people's living standards improve, home-use cabins are becoming increasingly popular, with various types of cabins, including hyperbaric oxygen chambers, atmospheric oxygen chambers, and safety cabins, attracting widespread attention.

[0003] With the large-scale construction of high-rise buildings, the related issues of high-rise building fires have attracted increasing attention. In the event of a fire, the existence of high floors forces people on higher floors to spend more time escaping and they are more likely to become exhausted during the escape process. This also shows that traditional escape methods are difficult to deal with high-rise fires.

[0004] However, due to limited home space, most users cannot install both an oxygen chamber and a safety chamber at the same time. Therefore, there is a need for a multi-functional chamber that has ventilation, cooling and oxygen supply functions to protect people in emergency situations, while also allowing people to rest and engage in activities in the chamber under normal conditions.

[0050] Furthermore, a control method for a multi-functional cabin is proposed to achieve control over its use, comprising the following steps: S1. After personnel enter cabin 1 or when a preset time is reached, the multi-functional cabin can collect external environmental status data through sensors to understand the external environmental status. Personnel can also actively set the environmental status. When the external environmental status is in an emergency state, proceed to step S2; when the external environmental status is in a normal state, proceed to step S3. S2.

S3. Under normal conditions, the ventilation system ventilates the air inside the cabin, while the oxygen supply system and refrigeration system supply oxygen and cool the cabin environment according to the needs of the personnel inside the cabin, in order to increase the oxygen content and regulate the cabin temperature under normal conditions.

[0051] Furthermore, in step S1, if the multi-functional cabin detects that the external conditions have reached a preset value (such as the temperature and flue gas reaching a specified standard), it will start directly.

[0052] Furthermore, step S2 includes the following specific steps: S21. Open exhaust module 3, open the first intake pipe, and close the second intake pipe; S22. After the harmful gas sensor detects that the smoke level inside the cabin 1 is lower than the preset value, the ventilation system is shut down. S23. After the oxygen content sensor detects that the oxygen content in the internal environment of the cabin 1 is lower than the preset value, the first oxygen supply module 7 is activated to supply oxygen to the internal environment of the cabin 1. S24. After the second temperature sensor detects that the temperature of the internal environment of the cabin 1 is higher than the preset value, the first cooling module 5 is activated to cool down the internal environment of the cabin 1.

[0053] Furthermore, in step S22, if the external temperature of the chamber 1 exceeds the standard during the ventilation operation, gas will no longer be introduced from the outside, or the first air intake pipe will be closed when the air filtration device has been used for a period of time exceeding a certain value (e.g., 30 minutes).

[0054] Furthermore, step S3 includes the following specific steps: S31. Open exhaust module 3, open the second intake pipe, and close the first intake pipe; S32. After the harmful gas sensor detects that the harmful gas in the internal environment of the chamber 1 is lower than the preset value and the internal pressure of the chamber 1 stabilizes, the ventilation system switches to silent mode. S33. Activate the second oxygen supply module 8 to supply oxygen to the internal environment of the cabin 1, and adjust the oxygen content as needed. S34. Start the second cooling module 6 to cool the internal environment of the cabin 1, and adjust the cabin temperature as needed.

[0055] Furthermore, such as Figure 4 As shown, step S31 includes an intake step A and an exhaust step B, wherein: Step A includes the following steps: A1. The ventilation system is started. The main control unit confirms whether it is a reservation. If yes, proceed to step A3. If not, proceed to step A2. A2. Set the intake fan (i.e., the second fan) to the maximum speed and run it for a period of time before proceeding to step A3. A3. The pressure inside the chamber 1 is detected by the chamber pressure sensor. If the chamber pressure is too high, the speed of the intake fan is reduced. At this time, the exhaust module 3 is also working in coordination until the chamber pressure is lower than the preset value and reaches stability, and then proceed to step A4. A4. Detect whether the harmful gas has been completely exhausted by the harmful gas sensor. If not, adjust the intake fan to the maximum speed. If it has been completely exhausted, complete intake step A and switch to silent mode. Step B includes the following steps: B1. The ventilation system is started. The main control unit confirms whether it is a reservation. If not, proceed to step B3. If yes, proceed to step B2. B2. Set the exhaust fan (i.e., the first fan) to the maximum speed and run it for a period of time before proceeding to step A3. B3. Detect the internal pressure of chamber 1 using the chamber pressure sensor. If the chamber pressure is too high, increase the speed of the exhaust fan until the chamber pressure is lower than the preset value and stabilizes, then proceed to step A4. B4. Detect whether the harmful gas has been completely exhausted using the harmful gas sensor. If not, adjust the exhaust fan to the maximum speed. If it has been completely exhausted, complete intake step B and switch to silent mode.

[0056] To further explain, in step A2, the running time is preferably 30~60s. In silent mode, the first and second fans are at their lowest speeds, which makes the ventilation system less noisy and ensures that users can rest.
