[0040] The sliding piece 2.3.2 comprises a sliding block, the sliding block is provided with a groove, the sliding rail 2.3.1 is provided with a protrusion along the length direction, and the groove is matched with the protrusion. The cross-sectional shape of the sliding rail 2.3.1 can be concave or convex, and correspondingly, the cross-sectional shape of the sliding block can be convex or concave.

[0041] The magnetic assembly 2.3.3 comprises a base 2.3.3.1, an electromagnet 2.3.3.2, and an elastic assembly 2.3.3.3. The base 2.3.3.1 is fixedly connected with the sliding piece 2.3.2. The electromagnet 2.3.3.2 is arranged on the base 2.3.3.1. The elastic assembly 2.3.3.3 is arranged on the base 2.3.3.1 and is located on the side close to the door frame 2.1. The elastic assembly 2.3.3.3 comprises a spring and a spring mounting seat. The spring is arranged on the base 2.3.3.1 through the spring mounting seat. When the door panel of the pressure-bearing door is closed, the spring is in abutment with the door frame 2.1 and is in a compressed state. The magnetic assembly 2.3.3 further comprises a permanent magnet. The permanent magnet is arranged on the bottom of the door panel 2.2 and is located on the side away from the door frame 2.1.

In this embodiment, the electric push rod is preferably adopted.

[0043] In specific use, the automatic closing and opening device for the pressure-bearing door provided in this embodiment is installed on the position close to the door frame on the opening and closing path of the door panel. The door panel of the pressure-bearing door is manually closed to a certain angle, so that the permanent magnet on the door panel and the electromagnet 2.3.3.2 (not powered) are in mutual adsorption. The booster fan is turned on, the fan starts to operate, the electromagnet 2.3.3.2 is powered, and the electromagnet 2.3.3.2 has a large magnetic force to be closely combined with the permanent magnet on the door panel when powered. The electric push rod is extended and is in contact with the sliding piece 2.3.2, the sliding piece 2.3.2 is pushed to move towards the door frame, the electromagnet 2.3.3.2 on the base 2.3.3.1 moves towards the door frame and simultaneously drives the door panel to move towards the door frame, until the door panel preliminarily contacts the door frame and compresses the sealing strip arranged on the door frame (at this time, the sealing strip is compressed by about 2 mm). Subsequently, under the condition that the pressure difference between the inside and outside of the booster sleeping cabin gradually increases, the door panel gradually compresses the sealing strip, so that the sealing between the door panel and the door frame is realized. At this time, the spring is in a compressed state. When the pressure difference between the inside and outside of the cabin reaches a certain level (equivalent to that the fan works for about 30 s), the electric push rod is automatically retracted (the electric push rod is not connected with the sliding piece 2.3.2, therefore, the sliding piece 2.3.2 does not move together with the electric push rod when the electric push rod is retracted), and simultaneously the power supply of the electromagnet 2.3.3.2 is stopped.

[0044] When the device suddenly stops working or there is a sudden power outage, the pressure relief sleep cabin will automatically open the pressure relief. When the air pressure inside and outside the cabin is balanced, the spring installed on the base 2.3.3.1 is compressed and acts on the door frame. Under the spring's rebound force, the sliding part 2.3.2 moves the base away from the door frame. At the same time, since the electromagnet 2.3.3.2 is inside the permanent magnet (close to the door frame), it can push the door panel away from the door frame. At this time, the door panel is opened at a certain angle to prevent the person living in the pressure relief sleep cabin from being poisoned by carbon dioxide due to lack of air circulation. At the same time, the electromagnet 2.3.3.2 is adsorbed with the permanent magnet, and the spring rebound distance is limited, and the electric push rod also limits the sliding distance of the sliding part 2.3.2. Therefore, the opening angle of the pressure-bearing door will not be too large, ensuring the privacy and comfort of the occupants and improving the quality of life.

[0052] The present invention also provides a control method for a pressurized sleep chamber, applicable to the pressurized sleep chamber described above, comprising the following steps: Users select operating modes and issue operating mode commands through the control system. The operating mode commands include leisure sleep mode, oxygen therapy mode, and oxygenation mode. According to the operation mode command, the oxygen supply system and the pressurized fresh air system 3 are controlled to operate, so as to adjust at least one of the parameters of equivalent altitude, oxygen concentration, carbon dioxide concentration and fresh air volume in the pressurized sleep chamber body 1.

[0053] When the operating mode is leisure sleep mode, the pressurized fresh air system 3 is controlled to ensure that the equivalent altitude inside the main cabin is ≤2500m and the fresh air volume is ≥20m³. 3 / ph, CO2 concentration ≤1000ppm; In this mode, only the pressurized fresh air system 3 operates, pressurizing the cabin according to the set pressure to reduce the equivalent altitude inside the cabin to 2500m or below. The relationship between the air pressure inside the cabin and the equivalent altitude can be calculated using the following formula: ; in: Altitude (meters); The air pressure at the desired altitude (Pascals); The standard atmospheric pressure at sea level is usually taken as 101325 Pascals. The standard temperature at sea level is generally taken as 288.15 Kelvin. The vertical temperature lapse rate is typically taken as 0.0065 Kelvin / meter. The gas constant for dry air is approximately 287.05 joules per kilogram. Kelvin); The acceleration due to gravity is approximately 9.80665 m / s². 2 ; The relaxation sleep mode primarily uses a booster fan to pressurize the cabin, creating an equivalent space at low altitudes to prevent insomnia caused by high-altitude environments. Through the coordinated operation of the flow meter and the booster fan, it provides the required fresh air volume (≥20m³) to meet the body's needs for relaxation sleep. 3 The carbon dioxide concentration is controlled to ≤1000ppm by adjusting the air quality sensor and the opening angle of the oxygen supply valve, thereby providing a comfortable and relaxing sleeping space.

[0054] When the operating mode is oxygen therapy mode, the pressurized fresh air system 3 is controlled to operate until the equivalent altitude inside the pressurized sleep chamber 1 is ≤2000m and then stops operating; the oxygen supply system is controlled to keep the oxygen concentration inside the pressurized sleep chamber 1 between 24% and 30%; after the preset time is reached, it automatically switches to leisure sleep mode or exits the chamber. This mode primarily controls the concentration of oxygen and carbon dioxide by adjusting the opening angle of the oxygen supply valve. When the carbon dioxide concentration approaches the control value, the booster fan is activated to increase the fresh air volume and reduce the carbon dioxide concentration; when the oxygen concentration approaches the control value, the oxygen supply is reduced. The relationship between the oxygen supply and the oxygen concentration inside the cabin is as follows: ; in: This refers to the oxygen concentration inside the cabin. It is the amount of oxygen supplied into the cabin by the oxygen generator per unit time. It is the amount of oxygen consumed by the human body through respiration per unit of time; It is the total volume of gas inside the cabin per unit time.

[0055] When switching from oxygen therapy mode to relaxation sleep mode, it is necessary to control the rate of oxygen decay to avoid excessive fluctuations in oxygen concentration that could cause discomfort. The relationship between the amount of fresh air introduced and the oxygen concentration is as follows: ; in: Indicates mode switching t The oxygen concentration in the cabin after minutes; Indicates the oxygen concentration inside the cabin at the initial stage of mode switching; This indicates the amount of fresh air introduced during the mode switching phase; The effective volume inside the cabin; Based on the set oxygen decay rate, in Given the information, the mode switching can be calculated. t Minutes later, the oxygen concentration in the cabin This allows us to determine the amount of fresh air introduced, and by controlling the amount of fresh air introduced, we can avoid excessive fluctuations in oxygen concentration that could cause discomfort to the human body.

[0056] When the operation mode is the oxygen-increasing mode, the booster fresh air system 3 and the oxygen supply system are controlled to operate simultaneously, so that the equivalent altitude in the cabin is ≤2500m, the fresh air volume is ≥20m 3 p.h, the oxygen concentration is maintained between 23% and 25%, and the CO2 concentration is ≤1000ppm; the calculation formula of the oxygen concentration in the cabin is as follows: ; Wherein: is the oxygen concentration in the cabin; is the oxygen amount supplied by the oxygen generator into the cabin per unit time; is the oxygen amount brought into the cabin per unit time by the booster fan, which depends on the ventilation volume of the booster fan and the oxygen content in the external air. Generally, the oxygen content in the external air is about 21%, if the ventilation volume of the booster fan is (unit: L / min), then ; is the oxygen amount discharged from the cabin per unit time by the booster fan, which is related to the oxygen concentration in the cabin and the ventilation volume of the booster fan, and can be expressed as . It should be noted that in actual calculation, since is the unknown quantity to be solved, it is an iterative calculation process, usually an initial value is assumed for calculation, and then the true value is approached by iteration; is the oxygen amount consumed by the human body per unit time, which is related to the number of people in the cabin and the activity state of the human body. If there are people in the cabin, and each person consumes oxygen milliliters per minute on average, then ; is the total volume of the cabin per unit time, and in the case that the booster fan and the oxygen generator are working simultaneously and there is no other gas generation or consumption in the cabin, .

[0057] In this embodiment, when the booster fresh air system 3 is controlled to operate, the power of the booster fan in the booster fresh air system 3 is P determined by the following relationship: ; Wherein: represents the altitude correction coefficient; is the actual altitude, is the target equivalent altitude, is the fresh air volume, is the integration efficiency of the booster fan and the air conditioner. Through the above formula, the power of the booster fan can be determined, which realizes low-energy-consumption operation while meeting the requirements of fresh air volume and equivalent altitude.
