The technical scheme provided by the utility model is as follows:
a multifunctional air outlet for a negative pressure ward of a health building comprises an air exhaust cavity arranged on a wall body, wherein the air exhaust cavity is communicated with a negative pressure unit through an air exhaust pipe; it has high efficiency filter, its characterized in that to exhaust intracavity demountable installation: an electric control air inlet shutter is installed on one side, close to the negative pressure ward, of the air exhaust cavity, and an electric control air exhaust shutter is installed on one side, far away from the negative pressure ward, of the air exhaust cavity; ultraviolet sterilizing lamps are arranged on two sides of the high-efficiency filter in the air exhaust cavity.
Furthermore, a pressure difference detector is arranged in the exhaust cavity and positioned on two sides of the high-efficiency filter.
Furthermore, the exhaust cavity is provided with a plurality of exhaust cavities and is positioned on one side of the bed head of the sickbed.
Furthermore, the bottom of the exhaust cavity is 10-30 cm away from the ground.
The utility model has the following beneficial effects:
this application is through the automatically controlled air inlet tripe of both sides installation at the exhaust chamber and the automatically controlled tripe of airing exhaust, and install sterilamp in high efficiency filter's both sides, realize airtight sterile function, after working a period, when needing to change high efficiency filter, the automatically controlled air inlet tripe of control is closed with the automatically controlled tripe of airing exhaust, open sterilamp, can carry out effectual disinfection to high efficiency filter's both sides and exhaust chamber, prevent effectively that the virus from scattering, the polluted environment, extensively be applicable to ordinary building and such as pass catch disease health building such as hospital.
Drawings
Fig. 1 is a schematic overall structure diagram of the embodiment.
In the figure: 1. an electric control air inlet shutter; 2. electrically controlling the air exhaust louver; 3. an exhaust duct; 4. a wall body; 5. a high efficiency filter; 6. an ultraviolet germicidal lamp; 7. a differential pressure detector; 8. a ventilation cavity.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
Examples
As shown in fig. 1, a multifunctional air outlet for a negative pressure ward of a health building comprises an air exhaust cavity 8 arranged on a wall 4, wherein the air exhaust cavity 8 is communicated with a negative pressure unit through an air exhaust pipe 3; demountable installation has high efficiency filter 5, its characterized in that in 8 exhaust chambers: an electric control air inlet shutter 1 is arranged on one side of the exhaust cavity 8 close to the negative pressure ward, and an electric control exhaust shutter 2 is arranged on one side far away from the negative pressure ward; ultraviolet sterilizing lamps 6 are arranged on two sides of the high-efficiency filter 5 in the exhaust cavity 8.
The multifunctional air outlet realizes the function of closed disinfection by installing the electric control air inlet shutter 1 and the electric control air exhaust shutter 2 on two sides of the air exhaust cavity 8 and installing the ultraviolet germicidal lamps 6 on two sides of the high-efficiency filter 5. After working for a period of time, when the high-efficiency filter 5 needs to be replaced, the electronic control air inlet shutter 1 and the electronic control air exhaust shutter 2 are controlled to be closed, the ultraviolet germicidal lamp 6 is turned on, the two sides of the high-efficiency filter 5 and the air exhaust cavity 8 can be effectively sterilized, viruses are effectively prevented from scattering, the environment is prevented from being polluted, and the high-efficiency air inlet shutter is widely applied to common buildings and healthy buildings such as infectious disease hospitals.
