In this embodiment, the second structure 160 is disposed between the first support mechanism 220 and the second support mechanism 230, and as the second structure 160 is deployed simultaneously with the deployment of the first side branch 153, a skeleton is disposed within the second structure 160 to maintain the shape of the second structure 160. As shown in fig. 2 and 3, a cross beam 800 is further disposed between the first telescopic rod 222 and the second telescopic rod 232 to ensure the tension at the first side branch 153 of the second structural body 160, and cooperate with the framework to better maintain the shape of the second structural body 160. As shown in fig. 9, 13 and 14, the second structural body 160 is partially received in the first cavity 110 to further improve the strength of the second structural body 160. The two ends of the beam 800 are further provided with a stop 801 to prevent the beam 800 from moving relative to the first telescopic rod 222 and the second telescopic rod 232. Crossbeam 800 includes a plurality of branches 810, and articulated and folding each other of accomodating through hinge 820 between the adjacent branch 810 still is provided with round pin shaft coupling assembling 830 between the adjacent branch 810, and each branch 810 is fixed through round pin shaft coupling assembling 830 after expanding to guarantee crossbeam 800 integral rigidity.
Further, the third supporting mechanism 240 includes a third body 241, a first exhaust mechanism 600 is disposed in the third body 241, the second air inlet 610 is communicated with the first cavity 110, the bottom of the third body 241 is provided with a roller 210, and the third body 241 accommodates a third telescopic rod 242 which can extend out from the top of the third body 241. The first air outlet end 520 and the second air inlet end 610 are arranged diagonally, which is beneficial for rapid diffusion of the gas entering the first cavity 110, for example, for a patient needing oxygen inhalation, air with higher oxygen content can be introduced from the first channel 530; when the first cavity 110 needs to be sterilized, sterilizing atmosphere can be introduced from the first channel 530; when it is necessary to remove or react the harmful material in the first chamber 110, a corresponding atmosphere may be introduced from the first passage 530.
Further, the fourth supporting mechanism 250 includes a fourth body 251, and a backup battery may be disposed in the fourth body 251 to ensure that the negative pressure system 10 can still operate when the external power supply to the negative pressure system 10 is stopped. The fourth body 251 is provided at the bottom thereof with a roller 210, and the fourth body 251 accommodates a fourth telescopic rod 252 which can be extended from the top thereof.
When the supporting device 200 is contracted, the first supporting mechanism 220, the second supporting mechanism 230, the third supporting mechanism 240 and the fourth supporting mechanism 250 can surround to form an accommodating space 280, and the closed structure 100 can be accommodated in the accommodating space 280 after being contracted and the cross beam 800 is folded, so that the portability of the negative pressure system 10 when being contracted is improved.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention, and it is therefore to be understood that the invention is not limited by the scope of the appended claims.
