Description

Technical Field

[0001] This utility model relates to the technical field of rehabilitation wards, and in particular to an air supply and diversion device for medical and elderly care rehabilitation wards. Background Technology

[0002] As iconic rooms in elderly care facilities, medical and rehabilitation wards have extremely high requirements for human thermal comfort and the health maintenance of the elderly population.

[0003] Existing air supply and diversion devices for rehabilitation wards, such as the clean and efficient air supply device for negative pressure wards disclosed in utility model patent application number 202120290568.7, mainly include a high-speed air duct, a main air duct, and a diversion device. Two high-speed air ducts are arranged on both sides of the main air duct, and a diversion device is installed at the upper end of the high-speed air duct. A static pressure box is installed inside the main air duct, and the two high-speed air ducts are installed on both sides of the static pressure box. A fan is installed inside the high-speed air duct. In use, the diversion plate of the diversion device forms an oblique block above the high-speed air duct, guiding the airflow sent by the external fan into the main air duct. The static pressure box of the main air duct achieves a smooth and quiet airflow, thereby replacing the gas in the negative pressure ward. When high-speed ventilation is required, the diversion plate is opened and placed close to the outer wall of the air supply device, the high-speed air duct is opened, and the fan in the high-speed air duct is started. The fan accelerates the airflow, speeding up the circulation of the air sent by the external fan, and realizing high-speed gas replacement in the negative pressure ward.

[0004] However, most existing air supply deflectors are fixed and cannot adjust the airflow direction, which can easily lead to excessively high wind speeds in local areas or dead air zones. Moreover, the devices are difficult to disassemble and clean, and the accumulation of impurities inside can easily cause mold and contamination, affecting the quality of air supply. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an air supply and diversion device for medical and rehabilitation wards that can not only guide the air supply direction to avoid excessive wind speed or dead air in local areas of the ward, but also facilitate the filtration of impurities and the easy disassembly and cleaning of the filter plate, thus ensuring air quality.

[0006] This utility model discloses an air supply and guiding device for a medical and rehabilitation ward, comprising an air supply mechanism; it also includes an exhaust mechanism, a filtration mechanism, multiple sets of guiding mechanisms, and a drive mechanism.

The air supply mechanism is connected to a fresh air system, the exhaust mechanism is activated to accelerate the gas delivery to the ward through the multiple sets of guiding mechanisms, the drive mechanism is activated to drive the multiple sets of guiding mechanisms to guide the gas supply direction, and the filtration mechanism filters the passing air.

[0007] Preferably, the air supply mechanism includes a connecting pipe, an air supply box, a baffle, and a knob. The connecting pipe is installed in the ward and connects to the inside of the fresh air system. The air supply box is installed on the connecting pipe and connects to the inside of the connecting pipe. The baffle is rotatably installed on the connecting pipe, and the knob is installed on the baffle. The fresh air system delivers fresh air to the air supply box through the connecting pipe, and the air supply box delivers fresh air to the ward. When the device is being maintained, the staff rotates the knob, which causes the baffle to rotate and block the connecting pipe.

[0008] Preferably, the connecting pipe is also marked with a rotary scale; by observing the relative position of the knob and the scale, the rotation angle of the knob can be easily determined, thereby determining the ventilation area.

[0009] Preferably, the exhaust system includes a thermometer, two sets of connecting plates, and two sets of exhaust fans. The thermometer is installed inside the air supply box, both sets of connecting plates are installed inside the air supply box, and the two sets of exhaust fans are installed on the two sets of connecting plates respectively. The temperature of the fresh air delivered to the ward is detected by the thermometer, and the staff controls the start of the two sets of exhaust fans to increase the flow rate of the fresh air and increase the air supply volume.

[0010] Preferably, the filtration mechanism includes a positioning frame, a sealing ring, a filter plate, two sets of connecting shafts, and hangers. The positioning frame and the sealing ring are installed inside the connecting pipe. The filter plate is slidably installed inside the positioning frame. Both sets of connecting shafts are rotatably installed on the connecting pipe, and the hangers are installed on the two sets of connecting shafts. After prolonged use, the operator removes the filter plate for cleaning. After cleaning, the filter plate is inserted back into the positioning frame. The filter plate, in conjunction with the sealing ring, filters the air to prevent air leakage. Then, the two sets of hangers are rotated to support the bottom of the filter plate.

[0011] Preferably, the guiding mechanism includes a rotating shaft, a guide plate, and a gear. The rotating shaft is rotatably installed inside the air supply box, the guide plate is installed on the rotating shaft, and the gear is installed on the rotating shaft. The driving mechanism drives the gear to rotate, the gear drives the rotating shaft to rotate, and the rotating shaft drives the guide plate to rotate to adjust the air supply direction.

[0012] Preferably, the drive mechanism includes a positioning frame, a crossbar, a solo rack, an electric cylinder, and a connecting block. The positioning frame is installed inside the air supply box, the crossbar is slidably installed inside the positioning frame, multiple racks are installed on the crossbar, the electric cylinder is installed inside the air supply box, and the connecting block is installed on the top of the electric cylinder and connected to the crossbar.
