[0031] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0032] like Figures 1-12As shown, the present invention provides a technical solution: an oxygen cabin automatic door device, comprising a cabin body 1 and a door body 7, a cabin door frame 2 is fixed on the left side of the cabin body 1, and two cabin door frames 3 are fixed on the inner side of one cabin door frame 2, and the surfaces of the two cabin door frames 3 are provided with first latching teeth 4, a base 5 is fixed on the side of the left side of the cabin body 1, and the surface of the base 5 is rotatably connected to a door arm 6 through a rotating shaft, and the side of the door arm 6 away from the base 5 is rotatably connected to the door body 7, and a driving motor 8 is fixed on the surface of the door arm 6, and the driving motor 8 is connected to a driving gear 9 through an output shaft on the side facing the door body 7, and a cabin door frame 10 is fixed on the outer peripheral surface of the door body 7, and the side of the driving gear 9 is meshed with an arc-shaped rack 11, and the inner side of the cabin door frame 10 is provided with a second latching tooth 12, and the surface of the arc-shaped rack 11 is provided with a positioning block 13, and the positioning block 13 A first limit block 14 and a second limit block 15 are respectively provided below and above the door frame 10, a first position sensor 16 is provided in parallel to the side of the first limit block 14, and a second position sensor 17 is provided in parallel to the side of the second limit block 15. The cabin body 1 is engaged with the second tooth 12 on the inner side of the cabin door frame 10 through the first tooth 4, and the first tooth 4 and the second tooth 12 are distributed in a ring shape, and the angular interval between each tooth of the first tooth 4 and the second tooth 12 is 10°, the arc-shaped rack 11 is fixed to the outer side of the cabin door frame 10, and the arc-shaped rack 11 and the first limit block 14 and the second limit block 15 are not in the same plane, the first limit block 14, the second limit block 15, the first position sensor 16, and the second position sensor 17 are all fixed to the inner side of the door arm 6, and the four are located in the same plane;

[0033] The specific operation is as follows: after a person enters the inner wall of the cabin body 1, he pulls up the door body 7. At this time, the door body 7 is closed but not locked, and the second latch 12 is stuck between the latch teeth of the first latch 4, and the two are misaligned. At this time, the driving motor 8 drives the driving gear 9 to rotate counterclockwise, and the driving gear 9 drives the arc-shaped rack 11 to make the positioning block 13 on its surface and the cabin door frame 10 rotate counterclockwise. The cabin door frame 10 rotates with the second latch 12, thereby making it further misaligned and engaged with the first latch 4, so that the door body 7 can no longer be opened;

[0034] When the positioning block 13 rotates counterclockwise, it contacts the second limit block 15. At this time, the positioning block 13 triggers the second position sensor 17, and the second position sensor 17 feeds back a signal to the drive motor 8 to stop the operation, thereby controlling the rotation angle of the second latch 12.

[0035] When the door body 7 needs to be opened, the driving motor 8 drives the driving gear 9 to rotate clockwise, so that the positioning block 13 rotates to contact the first limit block 14. At this time, the first position sensor 16 is triggered to stop the driving motor 8. At this time, the teeth of the second latch 12 rotate to between the teeth of the first latch 4. At this time, the door body 7 can be opened by pushing or pulling it outward;

[0036] Based on the above description, compared with the existing method of manually rotating the cabin door to achieve opening and closing, the present invention only needs to remotely control the output direction of the drive motor 8 to automatically lock or unlock the door body 7, avoiding the problem of certain physical strength requirements for traditional manual rotation to lock or open the cabin door. By saving manpower, it is more friendly to the elderly, thereby improving the user experience.

[0037] like Figures 1-12 As shown, a cylinder 18 is fixed to the inner side of the second cabin door frame 3, and the piston rod of the cylinder 18 passes through the second cabin door frame 3. The connection portion between the cylinder 18 and the second cabin door frame 3 is provided with a sealing silicone gasket, and the piston rod of the cylinder 18 passes through the sealing silicone gasket. A stopper 19 is fixed to the outer peripheral surface of the hatch door frame 10, and after the hatch door frame 10 is unlocked, the stopper 19 coincides with the end of the piston rod of the cylinder 18.

[0038] The specific operation is as follows: an oxygen sensor is installed inside the cabin 1. Based on the changes in oxygen content, when the oxygen content drops to a preset value at the end of the oxygen inhalation therapy, the drive motor 8 can automatically start to unlock the door 7. At this time, the cylinder 18 pushes the piston rod to extend to push the stopper 19, so that the door 7 and the door arm 6 are opened through the shaft on the base 5, allowing outside air to enter the cabin 1;

[0039] Based on the above description, the present invention is based on monitoring the oxygen content inside the cabin 1, so as to automatically control the cylinder 18 and the drive motor 8 to start at the end of the treatment course, so that the door 7 is automatically opened after being unlocked to allow outside air to enter the cabin 1, thereby avoiding the problem of hypoxia caused by the user in the cabin 1 being unable to push open the door 7 by himself due to sleep or other similar reasons.

[0040] like Figures 1-12 As shown, an armrest handle 20 is provided on the inner side of the door body 7, and the armrest handle 20 is located on the cabin body 1 after the door body 7 is closed. There are two armrest handles 20 in total, and a pressure sensor is embedded in each armrest handle 20;

[0041] The specific operation is as follows: in an emergency situation such as a power outage or when the person in the cabin needs to interrupt the treatment course and go out for an unexpected reason, the user in the cabin holds the armrest handle 20, and the pressure sensor inside the armrest handle 20 senses that the pressure value is higher than the preset value, and the duration exceeds the preset time, the drive motor 8 and the cylinder 18 are automatically started to unlock the door 7 and then automatically open. In order to prevent power outages, the cabin 1 is equipped with an emergency power supply, which switches to the emergency power supply in the event of a power outage so that the door 7 can still be opened automatically;

[0042] Based on the above description, the present invention allows users who need to exit the cabin midway due to emergencies to simply continue holding the armrest handle 20 so that the pressure value and duration are higher than the preset value to feedback signals to the drive motor 8 and cylinder 18, so that the two can start in turn and control the door body 7 to automatically open, thereby preventing the user from being locked in the cabin due to emergencies.

[0043] In summary, when the oxygen cabin automatic door device is used, first, a person enters the inner wall of the cabin body 1 and pulls up the door body 7. At this time, the door body 7 is closed but not locked, and the second latch 12 is stuck between the latch teeth of the first latch 4, and the two are misaligned. At this time, the driving motor 8 drives the driving gear 9 to rotate counterclockwise, and the driving gear 9 drives the arc-shaped rack 11 to make the positioning block 13 on its surface and the cabin door frame 10 rotate counterclockwise. The cabin door frame 10 rotates with the second latch 12, thereby causing it to further misalign and engage with the first latch 4, so that the door body 7 can no longer be opened;

[0044] When the positioning block 13 rotates counterclockwise, it contacts the second limit block 15. At this time, the positioning block 13 triggers the second position sensor 17, and the second position sensor 17 feeds back a signal to the drive motor 8 to stop the operation, thereby controlling the rotation angle of the second latch 12.

[0045] When the door body 7 needs to be opened, the driving motor 8 drives the driving gear 9 to rotate clockwise, so that the positioning block 13 rotates to contact the first limit block 14. At this time, the first position sensor 16 is triggered to stop the driving motor 8. At this time, the teeth of the second latch 12 rotate to between the teeth of the first latch 4. At this time, the door body 7 can be opened by pushing or pulling it outward;

[0046] An oxygen sensor is installed inside the cabin 1. Based on the changes in oxygen content, when the oxygen content drops to a preset value at the end of the oxygen inhalation therapy, the drive motor 8 can automatically start to unlock the door 7. At this time, the cylinder 18 pushes the piston rod to extend to push the stopper 19, so that the door 7 and the door arm 6 are opened through the shaft on the base 5, allowing outside air to enter the cabin 1.

[0047] In an emergency situation such as a power outage or when the people in the cabin need to interrupt their treatment and go out due to an emergency, the user in the cabin holds the armrest handle 20. The pressure sensor inside the armrest handle 20 senses a pressure value higher than a preset value, and after the pressure lasts for more than a preset time, the drive motor 8 and the cylinder 18 are automatically started to unlock the door 7 and then automatically open. In order to prevent power outages, the cabin 1 is equipped with an emergency power supply, which switches to the emergency power supply during a power outage so that the door 7 can still be opened automatically.

[0048] The embodiments of the present invention are presented for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described in order to better illustrate the principles of the invention and its practical application and to enable those skilled in the art to understand the invention and design various embodiments with various modifications as suited for specific applications.
