The invention discloses an air conditioner indoor unit and a full-space air supplying device thereof. A plurality of ventilating holes are formed in a left air sweeping blade and a right air sweepingblade, and the hole diameters of the ventilating holes in the faces, facing an air outlet, of the left air sweeping blade and the right air sweeping blade are smaller than those of the ventilating holes in the faces, back on to the air outlet, of the left air sweeping blade and the right air sweeping blade; under the situation that the air conditioner indoor unit enters into a full-space air supplying mode, the left air sweeping blade and the right air sweeping blade are in an air outlet flow pass blocking state, and the angle range of vertical swing of an air guiding plate is + / _60 degrees; an air outlet flow pass is blocked through the left air sweeping blade and the right air sweeping blade, so that most air flows flow out from the ventilating holes, and thus the better non-blowing-feeling experience effect is achieved; meanwhile through combination with limiting on the swing range of the air guiding plate, the comfort movement areas of users are widened, the indoor full-space non-blowing-feeling effect is better achieved, the comfort degree of the air conditioner indoor unit is increased, the user experience feeling is good, and the room constant temperature effect is also facilitated; and the structure is simple, and the original functions of the air conditioner indoor unit are also not influenced.

The invention discloses a multistage expansion type trolley. The trolley comprises a cargo carrying platform, a grab rail installed on the cargo carrying platform and used for pushing and pulling, andwalking wheels installed at the lower side of the cargo carrying platform, the cargo carrying platform is of a folding structure composed of a bearing plate and expansion plates arranged on the leftside and the right side of the bearing plate, the left expansion plate is hinged to the left edge of the bearing plate, the right expansion plate is hinged to the right edge of the bearing plate, andopening and closing limiting devices used for limiting the opening angles of the expansion plates are arranged between the expansion plates and the bearing plate; the left expansion plate and the right expansion plate are respectively provided with tooth parts which are matched with each other; drawing grooves with backward openings are formed in the bearing plate and the expansion plate, and drawing plates in sliding fit with the drawing grooves are arranged in the drawing grooves in a matched mode; and the drawing plates on the expansion plates are each of a turning plate type drawing platestructure. The occupied space of the trolley can be reduced, and the bearing area of the cargo carrying platform can also be expanded in a folding, drawing and turning multistage manner.

The invention discloses a pressure and flow restricting type ventilation / attraction machine for detecting a fiberoptic bronchoscopy, comprising a four way pipe arranged on an enclosure, wherein the four way pipe is respectively communicated with an intake tube, a fiberoptic bronchoscopy attraction hole, a negative pressure source and outside atmosphere; and the four way pipe comprises a valve body and an inner core sealed and connected with the inner wall of the valve body, wherein the inner core is provided with a path, a driving device is connected outside the inner core, and the path can ventilate or attract the bronchoscopy via the driving device. The invention solves the problem of hyoxemia commonly happening in the fiberoptic bronchoscopy examination; the ventilation / attraction machine can be directly used for pressure support ventilation without pulling out the fiberoptic bronchoscopy so as to maintain the normal arterial partial pressure of oxygen of patients; meanwhile, theinvention avoids barotraumas, improves the safety and the success rate for the fiberoptic bronchoscopy examination, expands the application range of the fiberoptic bronchoscopy and does not affect the original function of the fiberoptic bronchoscopy. The invention has simple structure, stable performance and high safety, and is convenient in use. The invention is suitable for any patient to do the fiberoptic bronchoscopy examination, especially patients with intensive care. The invention is especially used for neonate patients of respiratory failure.
