[0002] In clinical practice, medical staff need to regularly clean the patient's mouth, so they use corresponding oral care appliances. Currently, the oral care sticks commonly used in clinical practice can only be used for oral care. If oral irrigation is required, it is necessary to use other tools to assist, and it requires the assistance of both hands or a second person to assist, which wastes manpower.

[0003] In the prior art, the utility model patent with announcement number CN209984340U discloses a negative pressure suction toothbrush for oral care. By setting a negative pressure suction head and an atomizing nozzle, it can realize negative pressure suction and atomizing flushing while cleaning the patient's mouth, that is, the same device can achieve the effects of cleaning, flushing and suction discharge.

[0004] However, the above structure has the following problems in actual use:

[0005] Since the above structure has both negative pressure suction and positive pressure atomization flushing, in actual use, it is easy for the water sprayed from the atomization nozzle to be sucked out through the negative pressure suction head under the action of negative pressure before it is fully cleaned. That is, the operation of negative pressure will affect the cleaning effect of the sprayed water. In order to avoid this phenomenon, medical staff have to manually close the switch valve of the negative pressure suction device when performing spray flushing. The frequent switching between positive pressure flushing and negative pressure suction brings great inconvenience to the operation of medical staff, and sometimes even another medical staff is required to operate the switch valve of the negative pressure suction device. Utility Model Content

[0024] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0025] As shown in the accompanying drawings, this embodiment provides an oral irrigator, which includes a cleaning rod 1, the end of which is connected to a cleaning brush head 2, and a negative pressure suction port 31 is provided on the surface of the cleaning brush head 2; the cleaning rod 1 includes a mutually fixed and independent negative pressure tube 3 and a water inlet pipe 4, wherein the negative pressure tube 3 is a hard tube structure with a certain support force, which facilitates the handheld cleaning rod 1 to be inserted into the patient's oral cavity; the input port of the negative pressure tube 3 is connected to the negative pressure suction port 31, and the output port of the water inlet pipe 4 is connected to the liquid outlet 41, which is provided on the cleaning rod 1 (specifically, on the water inlet pipe 4) near the cleaning brush head 2. In other embodiments, the liquid outlet 41 can also be provided on the cleaning brush head 2.

[0026] The cleaning stick 1 is also provided with a reservoir 5 for storing oral care liquid, and the outlet of the reservoir 5 is connected to the water inlet pipe 4. When rinsing is required, the oral care liquid in the reservoir 5 can be squeezed, and the care liquid is sprayed out through the liquid outlet 41 to reach the area to be rinsed. The reservoir 5 is provided with an inlet (not shown in the drawings) for pouring oral care liquid into it, and the inlet is closed after the oral care liquid is poured.

[0027] In this embodiment, the output end of the negative pressure tube 3 is connected to a connection port 32 for connecting to a negative pressure suction device. The negative pressure tube 3 is also provided with a side opening 6 that communicates with the interior of the negative pressure tube 3. The side opening 6 is located on the output side of the connection port 32, and a corresponding sealing plug 7 is provided at the side opening 6. When the negative pressure suction device is in operation, inserting the sealing plug 7 into the side opening 6 allows the negative pressure tube 3 to form a passage, allowing the negative pressure suction device to function properly. When the sealing plug 7 is removed, the negative pressure tube 3 is depressurized at the side opening 6, and the negative pressure suction port 31 no longer forms a negative pressure suction effect.

[0028] Before use, the connection port 32 is connected to a negative pressure suction device, and the storage capsule 5 stores oral care liquid.

[0029] When in use, the negative pressure suction is activated, and the side opening 6 is open, that is, the sealing plug 7 is not inserted to seal it; the cleaning rod 1 is held and the cleaning brush head 2 is inserted into the patient's oral cavity, and the care liquid in the storage bag 5 is squeezed to be sprayed out through the liquid outlet 41 to reach the area to be rinsed. At this time, no negative pressure is generated at the negative pressure suction port 31, thereby avoiding the interference of negative pressure on the spraying and brushing, that is, the sprayed care liquid will not be sucked away by the negative pressure, and the cleaning brush head 2 can be used for effective brushing; as the brushing progresses, when it is necessary to suck out the waste liquid in the oral cavity, the sealing plug 7 can be inserted into the side opening 6 to seal it, and negative pressure is generated at the negative pressure suction port 31, and the waste liquid is smoothly sucked out through the negative pressure suction port 31; when it is necessary to rinse again, the sealing plug 7 can be pulled out. Since the side opening 6 and the sealing plug 7 that cooperates with it are arranged on the negative pressure tube, a single person can complete the operations such as operating the cleaning rod and removing the plug, without the cooperation of other personnel, and without repeatedly turning the negative pressure suction device on and off, which makes the operation more smooth and convenient.

[0030] In a preferred embodiment of the present invention, the side opening 6 is arranged close to the storage bag 5, which is more convenient for the operator to operate and switch between negative pressure suction and extrusion spray.

[0031] In a preferred embodiment of the present invention, a one-way flow structure is provided at the connection between the outlet of the reservoir 5 and the water inlet pipe 4. The purpose is to ensure that the liquid outlet 41 can spray liquid only when the reservoir 5 is actively squeezed, and to avoid the phenomenon of the care liquid in the reservoir 5 flowing out naturally due to gravity. Figure 2 As shown, the one-way flow structure is a silicone tube 8, one end of which is open and fixed on the inner wall of the storage bag 5 or the inner wall of the water inlet pipe 4, and the other end of the silicone tube 8 is facing the output direction of the water inlet pipe 4, and this end is in a closed state with the inner wall in a natural state, so as to prevent the care liquid in the storage bag 5 from flowing out naturally. When the storage bag 5 is squeezed hard, the care liquid enters the silicone tube and opens this end to form a water outlet passage.

[0032] In a preferred embodiment of the present invention, the water inlet pipe 4 is located on both sides of the negative pressure pipe 3 and fixed on its outer wall. Figure 3 As shown, the two are integrated into a cleaning rod, which can avoid redundant pipelines, improve the integrity, and ensure the liquid output of the two water inlet pipes.

[0033] In a preferred embodiment of the present invention, the cleaning brush head 2 is a sponge brush 21 structure, and a bristle brush 22 is provided at the side end of the sponge brush 21. The cleaning brush head with both sponge brush 21 and bristle brush 22 structures has a better cleaning effect.

[0034] In addition, the oral irrigator of this solution can also be designed as a disposable item to meet clinical needs.
