Description

Technical Field

[0001] The utility model relates to the technical field of air diversion in smart hospitals, in particular to a top-mounted flip diversion device for smart hospital wards. Background Art

[0002] Hospital operating rooms can be divided into general operating rooms and clean operating rooms according to environmental requirements and use departments. The current clean operating room is an important measure to prevent infection, and positive pressure and negative pressure are two air flow modes in the operating room. Positive pressure means that the pressure of the indoor air in the operating room is higher than that of the outside environment, thus forming a clean air flow. Negative pressure is the opposite, which means that the air pressure in the operating room is lower than that of the outside environment, thus forming an inflow of air to prevent the spread of pathogenic microorganisms through airflow.

[0003] The current positive and negative pressure adjustment method is mainly achieved through the air flow direction inside the ventilation duct. This method can only be achieved through the main fan. The positive and negative pressure states cannot be quickly switched and adjusted inside a single operating room, and the integration of the entire diversion mechanism and the integrated ceiling on the ceiling is not high. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the current positive and negative pressure adjustment method cannot quickly switch and adjust a single operating room, and the integration of the entire guide mechanism and the integrated ceiling on the ceiling is not high.

[0019] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Figure 1 , Figure 2 and Figure 3 A ceiling-mounted flip deflector device for a smart hospital ward is shown, comprising an integrated ceiling with an integrated ceiling aluminum gusset plate 1 installed inside and an internal mounting frame 2 installed on the integrated ceiling aluminum gusset plate 1, the internal mounting frame 2 is equipped with an electrically controlled deflector 3 inside, the electrically controlled deflector 3 is equipped with a high-speed centrifugal fan 4 inside, the electrically controlled deflector 3 comprises a main assembly hood 31 installed in the internal mounting frame 2, lateral assembly frames 32 fixed on both sides of the main assembly hood 31, an electrically controlled arc deflector 33 movably installed in the lateral assembly frame 32 through assembly axes on both sides, a lifting and closing cover 34 installed on the upper and lower ends of the main assembly hood 31, and lateral control mechanisms arranged on both sides of the main assembly hood 31.

[0022] Working principle: when it is necessary to adjust the indoor positive pressure, the electrically controlled arc-shaped air guide covers 33 on both sides of the main assembly cover 31 begin to flip, with the air outlet facing downward, and the lifting and closing cover plate 34 is lifted upward, so that the air exhaust port at the upper end of the main assembly cover 31 is opened and the air exhaust port at the lower end is closed. At this time, the high-speed centrifugal fan 4 rotates at high speed, draws air from the upper end, and then blows air into the room through the electrically controlled arc-shaped air guide covers 33 on both sides, generating positive pressure; and when it is necessary to adjust the indoor positive pressure, the electrically controlled arc-shaped air guide covers 33 on both sides of the main assembly cover 31 begin to flip, with the air outlet facing upward, and the lifting and closing cover plate 34 descends, so that the air exhaust port at the lower end of the main assembly cover 31 is opened and the air exhaust port at the upper end is closed. At this time, the high-speed centrifugal fan 4 rotates at high speed, draws air from the lower end, and then blows air into the ventilation duct through the electrically controlled arc-shaped air guide covers 33 on both sides, generating positive and negative pressure.

[0023] In order to facilitate air extraction, the upper and lower ends of the main assembly cover 31 are both provided with lateral air extraction ports that cooperate with the lifting and closing cover plate 34.

[0024] In order to cooperate with electric control, the electrically controlled arc-shaped air deflector 33 includes an adjusting motor 331 installed inside the main assembly cover 31, a lateral air deflector 332 movably installed on the inner side of the lateral assembly frame 32, and a transmission gear set 333 for transmitting the adjusting motor 331 and the lateral air deflector 332.

[0025] The transmission gear set 333 includes a control gear axially fixed on the outer rotating shaft of the adjusting motor 331 and a driven gear axially sleeved on the outer connecting shaft of the lateral air guide cover 332. The control gear and the driven gear are meshed with each other. The adjusting motor 331 drives the driven gear and the lateral air guide cover 332 to rotate through the control gear, thereby changing the angle of the air outlet.

[0026] In order to facilitate the storage of the lateral transmission mechanism, lateral adjustment grooves 35 for accommodating the lateral control mechanism and the lifting and closing cover plate 34 are opened on both side walls of the main assembly cover 31.

[0027] In order to cooperate with lateral transmission, the lateral control mechanism includes end transmission gears 6 movably connected to the transverse transmission shaft 5, axially fixed on both sides of the transverse transmission shaft 5, and a central adjustment gear 7 axially sleeved on the middle position of the transverse transmission shaft 5. The outer side surface of the lifting and closing cover 34 has a lateral adjustment tooth groove that meshes with the central adjustment gear 7.

[0028] When the lateral air guide cover 332 rotates, the lateral transmission shaft 5 is driven to rotate through the side end gear meshing with the end transmission gear 6. The rotation angles of the lateral air guide covers 332 on both sides are ensured to be opposite, thereby ensuring that the air outlets on both sides of the main assembly cover 31 are synchronously facing the room or the ventilation duct at the top. When the air outlets on both sides of the main assembly cover 31 are synchronously facing the room, the air flows from the ventilation duct at the top into the operating room, and a positive pressure is generated inside the operating room; and when the air outlets on both sides of the main assembly cover 31 are synchronously facing the ventilation duct at the top, the air flows from the operating room to the ventilation duct at the top, and a negative pressure is generated inside the operating room.

[0029] In order to avoid the inhalation of dust, a metal filter 334 is installed inside the side air intake port.

[0030] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
