Description

Technical Field

[0001] The utility model belongs to the technical field of air purification devices, and in particular relates to an air purification device suitable for a cabin. Background Art

[0002] As an important carrier for carrying out specific tasks, special shelters have extremely high requirements for the quality of the internal environment. Recently, the air purification equipment of special shelters still uses ordinary electric ventilation devices, which have low purification efficiency and cannot quickly remove pollutants such as particulate matter, harmful gases and microorganisms in the air. They have low adaptability in extreme environments such as the wild and desert, and cannot provide a clean and safe breathing environment for the personnel in the cabin, which directly affects the successful completion of the mission.

[0003] Special cabin air purification device is a key equipment to ensure the environmental quality in the cabin. The existing mobile vehicle-mounted panel-type building cabin ventilation and sterilization technology is lacking in application. There is a need for an air purification device with good air tightness, high electromagnetic shielding performance, high-efficiency and environmentally friendly air purification capacity, adaptability to complex environments and small thickness.

[0004] The patent document with publication number CN105134044A discloses a dual-circulation purification window, wherein an indoor end air duct and an outdoor end air duct are provided on the window stile; an outdoor air inlet with an air inlet door driven to be opened and closed by a motor A is provided on the window stile at the lower end of the outdoor end air duct; an outdoor air outlet with an exhaust door driven to be opened and closed by a motor B is provided on the window stile at the upper end of the outdoor end air duct; a group of filters are installed in the outdoor end air duct at the air inlet, an air inlet unit is installed in the indoor end air duct, another group of filters is installed at the upper end of the air inlet unit, and an internal circulation air door is installed at the upper end of the other group of filters; an indoor air inlet is provided on the window stile at the indoor end of the air inlet unit; an electrostatic adsorption brush is installed on the upper part of the indoor air inlet; an exhaust unit with an indoor exhaust outlet on the window stile at the indoor end is installed in the indoor end air duct at the exhaust outlet.

The filter 11 is electrically connected to the disinfection lamp 7, the limit device 9, the window opener 10 and the system control unit 12. The ventilation plate 13 is made of stainless steel, and a honeycomb ventilation portion 28 is arranged on the ventilation plate 13. The filter 11 can effectively block external electromagnetic interference signals from entering the interior of the cabin, prevent the signals generated by the internal electronic equipment from radiating outward, and at the same time ensure that the device can work normally in a complex electromagnetic environment and reduce mutual interference; the ventilation plate 13 plays a role in taking into account both EMI shielding and good ventilation.

[0040] The ventilation component 3 includes a window frame 5, a cover plate 6, a disinfection lamp 7, a window opener 10 and a drive control system. The window frame 5 is arranged on a fixed wall 4. One side of the cover plate 6 is hinged to the window frame 5. The disinfection lamp 7 and the window opener 10 are arranged on the window frame 5.

[0047] S1: The air purification device is provided with an opening and closing button. When the air purification device is in the closed state of the cover plate 6 and the window frame 5, the fork 24 contacts the micro limit switch A22. After the opening and closing button is pressed to power on the device, the drive motor 26 drives the chain tightening reel 25 to rotate, and the chain 27 extends outward. As the chain 27 continues to extend outward, the opening angle of the cover plate 6 gradually increases. When the fork 24 contacts the micro limit switch B23, the opening angle of the cover plate 6 reaches the maximum, and the drive motor 26 stops working to complete the opening step.

[0048] S2: Press the opening and closing button to make the drive motor 26 receive the closing signal. The drive motor 26 drives the chain tightening reel 25 to rotate in the opposite direction, the chain 27 shrinks, and the cover 6 gradually closes. When it is fully closed, the shift fork 24 contacts the micro limit switch A22, and the drive motor 26 stops working, completing the closing step.

[0049] The disinfection ventilation operation includes the following steps:

[0050] S1: The ventilation component 3 is powered on, the device is pressed to start the disinfection button switch, the disinfection lamp 7 starts to work and emits ultraviolet light, the window opener 10 drives the cover plate 6 to quickly rotate along the upper side of the window frame 5 to open, and the limit device 9 controls the opening angle of the cover plate 6 and the window frame 5. After the cover plate 6 rotates to a fixed angle, the limit device 9 feeds back an electrical signal to the drive control system, and the drive control system controls the window opener 10 to stop working, completing the disinfection and opening and closing actions.

[0051] S2: Press the device to turn off the disinfection button switch, the window opener 10 drives the cover 6 to quickly rotate and close along the upper side of the window frame 5. After the cover 6 is completely closed, the limit device 9 feeds back an electrical signal to the drive control system, and the drive control system then controls the window opener 10 to stop working, and the disinfection lamp 7 is delayed to extinguish. At this time, the sealing strip 8 is compressed and deformed by force, and the cover 6 and the sealing strip 8 are tightly fitted together to achieve airtight isolation between the inside and outside of the cabin.

[0052] The utility model adopts the control technology of chain window opener and limit device, and the window frame 5, cover plate 6 and the like adopt integrated aluminum alloy die-casting technology, so as to control the overall embedded thickness of ventilation components to be less than 50mm. The utility model is mainly suitable for use in enclosed places of plate-type shelter buildings such as special military vehicle-mounted shelters, medical shelters, and ship-mounted shelters. The key to the utility model device lies in the core mechanism of the airtight performance control of the cover plate 6 and the window frame 5, which is mainly realized by the fusion of the chain window opener 10 and the limit device 9.
