Description

Technical Field

[0001] This application relates to the field of medical doors, and more specifically, to a contactless swing airtight medical door. Background Technology

[0002] Due to the special nature of the medical environment, hygiene requirements are high. As medical doors are frequently opened and closed, hygiene needs should be given even more attention.

[0003] The product's structure can be referenced from a contactless swing medical door disclosed in Chinese Patent Document 202220651969.5, belonging to the technical field of medical doors. This utility model forms a swing door by hinged installation of one side of the door body onto the door frame, adapting to installation requirements with limited doorway space. A drive motor is installed on the door frame or wall and connected to the door body via a connecting rod. Monitoring sensors are installed on the door frame, wall, or door body. The drive motor and connecting rod drive the door body to rotate, thereby achieving automatic opening and closing of the door on the door frame. Furthermore, the detection sensors detect pedestrians at the door, providing control for automatic opening and closing. No manual opening or closing is required, and no door handle is needed. This avoids hygiene contamination problems caused by manual opening and closing, as well as hygiene dead zones caused by door handles, reducing the risk of cross-infection and meeting the high hygiene requirements of medical applications.

[0004] However, this patented medical door does not have a regular dust extraction function. As medical doors are used for a long time, dust will accumulate in the gaps between the door body and the door frame. Excessive dust may affect the use of the medical door.

[0005] We now offer a contactless, airtight, swing-type medical door. Summary of the Invention

[0006] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0007] To address the technical problems mentioned in the background section, some embodiments of this application provide a contactless swing-type airtight medical door, comprising: a door frame; a sliding groove formed on the door frame; a door body movably mounted on the door frame via the sliding groove; a vacuum cleaner fan movably mounted on the door body; an air inlet pipe disposed at one end of the vacuum cleaner fan, with the air inlet pipe corresponding to the gap between the door frame and the door body; a fan hood fixedly connected to the air inlet pipe of the vacuum cleaner fan; two mounting bases symmetrically fixedly connected to the door body; and a moving assembly disposed on the door body for moving the vacuum cleaner fan up and down. A collection box is fixed to the door; an exhaust duct is located at one end of the vacuum cleaner fan, between the vacuum cleaner fan and the collection box, and the exhaust duct of the vacuum cleaner fan is connected to the collection box, and the exhaust duct of the vacuum cleaner fan is a flexible hose; a first filter is fixed inside the collection box; a cleaning component is located on the collection box for cleaning the first filter; a second filter is movably located inside the collection box and is situated to one side of the first filter; a shaking component is located on the collection box for shaking the second filter; an opening is located at the bottom of the collection box; a cover is located on the opening for sealing the opening; a fixing component is located on the collection box for fixing the cover; and an air outlet is located on the side panel of the collection box.

[0008] When cleaning dust between the door and frame, first start the vacuum fan. Dust enters the inlet pipe through the hood and then the outlet pipe into the collection box. The collection box collects the dust. Rotating the fixing bolts allows the sealing plate to be opened via the handle, enabling workers to clean the dust. The first and second filters provide double isolation for dust, preventing it from escaping. Simultaneously, the servo motor can be activated, causing its output shaft to drive the lead screw, which in turn moves the moving base up and down, thus moving the vacuum fan and improving suction efficiency. The first disc and the first belt cause the screw to rotate, which in turn causes the cleaning brush to move up and down. The cleaning brush cleans the first filter screen, preventing dust from adhering to it and affecting the airflow. The second belt and the second disc cause the connecting rod to rotate. The meshing of the driving and driven bevel gears causes the rotating rod to rotate, which in turn causes the abutment rod to rotate. The abutment rod abuts against the second filter screen, and the vibration spring causes the second filter screen to vibrate, further preventing dust from adhering to it and ensuring that the air is finally discharged through the air outlet.

[0009] Furthermore, the moving component includes a lead screw and a moving base. The moving base is disposed between two mounting bases, and the vacuum cleaner fan is fixedly connected to the moving base. The lead screw is rotatably mounted between the two mounting bases and is threadedly connected to the moving base. A servo motor is fixedly connected to one of the mounting bases, and the output shaft of the servo motor is fixedly connected to the lead screw. Furthermore, the cleaning component includes a cleaning brush, which is disposed in a collection box and contacts a first filter screen. Connecting seats are rotatably mounted on both ends of the cleaning brush, and the connecting seats are disposed in the collection box. A lifting component for moving the cleaning brush up and down is provided on the collection box.

[0010] Furthermore, the lifting assembly includes a screw, which is rotatably mounted between two side plates of the collection box and threadedly connected to the connecting seat. The screw extends to the outside, and a first linkage assembly is provided between the screw and the lead screw. A limit rod is fixedly connected to the collection box, which passes through the connecting seat and is slidably mounted with the connecting seat.

[0011] Furthermore, the first linkage component includes two first discs and a first belt. The two first discs are respectively fixed to the screw and the lead screw, and the first belt drive is installed between the two first discs.

[0012] Furthermore, the shaking assembly includes a shaking spring, which is fixedly connected to the side plate of the collection box, and a sliding rod is fixedly connected to the side plate of the collection box. A perforation is provided on the second filter screen, and the sliding rod passes through the perforation and is slidably installed with the perforation. An abutment assembly is provided on the collection box.

[0013] Furthermore, the contact assembly includes a contact rod, a rotating rod is rotatably mounted on the side plate of the collection box, and the contact rod is fixedly connected to the rotating rod, and the contact rod corresponds to the second filter screen. A driven bevel gear is fixedly connected to the rotating rod, a connecting rod is rotatably mounted on the side plate of the collection box, and a driving bevel gear is fixedly connected to the connecting rod. The driving bevel gear meshes with the driven bevel gear, and a second linkage assembly is provided between the connecting rod and the screw.

[0014] Furthermore, the second linkage component includes a second disc and a second belt, with the two second discs respectively fixed to the connecting rod and the screw, and the second belt drive installed between the two second discs.

[0015] Furthermore, the fixing component includes a fixing bolt, which is threadedly connected to the collection box and threadedly connected to the sealing plate.

[0016] Furthermore, a handle is fixedly attached to the bottom of the sealing plate.
