By starting the suction pump 34, negative pressure is generated, and the dirt and liquid are conveyed through the hose 32 to be stored inside the suction bottle 33, and thus the flushing and suction of the oral and maxillofacial region can be completed. The suction nozzle 29 is inserted and movably arranged on one side of the auxiliary plate 28. After the suction of the dirt and liquid is completed, the suction nozzle 29 is moved towards the side close to the auxiliary plate 28, and the first magnet disk 30 and the second magnet disk 31 gradually approach. Due to their magnetic connection, the suction nozzle 29 can be received on one side of the auxiliary plate 28.

[0037] A flushing method for a portable oral and maxillofacial flushing and suction device includes the following steps:

[0038] First step: The patient's chin is abutted against the surfaces of two rubber pads 36, the mouth is opened. One end of the third L-shaped tube 17 is connected to physiological saline in advance, and then the water pump 14 is started. The physiological saline will be conveyed along the corrugated pipe 11, the first L-shaped tube 12 and the second L-shaped tube 13 to the inside of the flushing nozzle 16.

[0039] Second step: The physiological saline is used to flush the oral and maxillofacial region through the flushing nozzle 16, and the dirt and liquid in the mouth are flushed down to keep the mouth clean.

[0040] Third step: The staff circularly pulls the pull plate 24 to make the cleaning plate 23 rotate circularly inside the chute. At this time, one ends of a plurality of brush strips 25 are respectively rubbed against the inner surface of the flushing cylinder 1, and the bottom surface of the scraping plate 26 is rubbed against the bottom end inside the flushing cylinder 1. After rotating one circle, the dirt attached to the inner wall of the flushing cylinder 1 can be scraped to one side, which is convenient for the staff to centrally clean.

[0041] Fourth step: The staff pulls the suction nozzle 29 to one side, the first magnet disk 30 and the second magnet disk 31 are gradually separated, the end of the suction nozzle 29 is aligned with the dirt and liquid in the oral and maxillofacial region, and the suction pump 34 is continuously started to generate negative pressure. The dirt and liquid are conveyed through the hose 32 to be stored inside the suction bottle 33, and thus the flushing and suction of the oral and maxillofacial region can be completed.

[0042] The working principle and usage process of the present invention: The portable oral and maxillofacial irrigation and suction device is a device used for cleaning and care of the oral and maxillofacial areas. It is widely used in dental clinics, hospitals and home care. It is mainly used to remove food residues, plaque, blood debris in the oral cavity, and help clean the postoperative area to reduce the risk of infection. Its portability makes it suitable for use in mobile environments, such as emergency, postoperative care, and home oral care scenarios. The device draws cleaning liquid from the water tank through a water pump and transports it to the nozzle through a hose, forming a water flow with a certain pressure, which is sprayed into the oral cavity and maxillofacial area for irrigation. Before use, make sure there is enough cleaning liquid in the water tank, check the hose, nozzle and suction device, and adjust the water flow pressure, suction and working force as needed. Mode, put the nozzle and suction device into the oral cavity and the area to be cleaned, start the equipment, rinse and suction. After the oral and maxillofacial rinsing, dirt will adhere to the inner wall of the cylinder storing the cleaning liquid, and the dirt cannot be cleaned in a centralized manner. There are dead corners, and the staff will need to spend more time cleaning in the later stage, which is time-consuming and labor-intensive. The height of the nozzle used for rinsing cannot be adjusted, and the scope of use is limited. The space for storing the liquid after rinsing is limited. For this reason, a portable oral and maxillofacial rinsing and suction device and a rinsing method thereof are designed. The patient's chin rests on the surface of two rubber pads 36, and the mouth is opened. The rubber pad 36 made of rubber reduces the squeezing force between the chin and the jaw support frame 35, and improves the use of the device. One end of the third L-shaped tube 17 is connected to physiological saline in advance. Then start the water pump 14, and the physiological saline will be guided to the inside of the flushing nozzle 16 along the bellows 11, the first L-shaped tube 12 and the second L-shaped tube 13. The physiological saline will be flushed to the oral cavity and maxillofacial area through the flushing nozzle 16 to flush out the dirt and liquid in the oral cavity and keep the oral cavity clean. After turning the torsion rod 19 clockwise, the screw rod 7 fixedly connected thereto is driven to rotate, which also drives the adjustment block 8 mounted thereon to move upward. Under the connection of the adjustment plate 9, the height of the guide tube 15 and the flushing nozzle 16 gradually increases, and the bellows 11 can be extended and stretched after being stressed. By turning the torsion rod 19, the position height of the flushing nozzle 16 can be adjusted, thereby increasing the use range of the device. The staff pulls the pull plate 24 in a circle so that the cleaning plate 23 is moved in a circle inside the slide groove. The washing tube 1 is rotated in circles. At this time, one end of the multiple brush strips 25 scrapes against the inner surface of the washing tube 1 respectively, and the bottom surface of the scraper 26 scrapes against the bottom end of the inside of the washing tube 1. After one circle of rotation, the dirt attached to the inner wall of the washing tube 1 can be scraped to one side, which is convenient for the staff to concentrate on cleaning. The physiological saline used for flushing is guided to the inside of the wrapping cover 2 for collection through the multiple leakage holes 22. The overflow cover 18 increases the wrapping area of ​​the outer periphery of the washing tube 1. The overflow cover 18 can collect the physiological saline used for flushing. Through the coordinated use of the wrapping cover 2 and the overflow cover 18, the storage area of ​​the physiological saline is increased. The staff pulls the suction nozzle 29 to one side, and the first magnet disk 30 and the second magnet disk 31 are gradually separated. One end of the suction nozzle 29 is aligned with the dirt and liquid on the oral and maxillofacial surface.Continue to start the suction pump 34 to generate negative pressure, and guide the dirt and liquid to the internal storage of the suction bottle 33 through the hose 32, then the flushing and suction of the oral and maxillofacial region can be completed. The suction nozzle 29 moves in an interspersed manner on one side of the auxiliary plate 28. After the suction of the dirt and liquid is completed, move the suction nozzle 29 towards the side close to the auxiliary plate 28. The first magnet disk 30 and the second magnet disk 31 gradually approach. Since the two are magnetically connected, the suction nozzle 29 can be received on one side of the auxiliary plate 28. By pulling the suction nozzle 29, the distance between the suction nozzle 29 and the oral and maxillofacial region can be adjusted.

[0043] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
