DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0021] like Figures 1 to 5 As shown, the flushing and suction oral protection sputum suction tube includes a handle 1, a cleaning head 2, a suction tube 3, a water injection structure 4, a suction tube closing structure 6 and a water injection driving wheel 5; the cleaning head 2 is connected to the front end of the handle; the handle 1 is provided with a liquid cavity 11, a liquid hole 14, a suction hole 15 and a guide hole 12, the liquid cavity 11 is arranged along the length direction of the handle 1 and is located at the rear end of the handle 1, the liquid hole 14 extends from the front end of the liquid cavity 11 to the cleaning head 2, the guide hole 12 is arranged along the length direction of the handle 1, and the suction hole 15 extends to the cleaning head 2; the water injection structure 4 includes a piston 44, a piston rod 4 1 and a driving bar 42, a piston 44 is located in the liquid chamber 11 and cooperates with the liquid chamber 11, a piston rod 41 is connected to the piston 44, the driving bar 42 is inserted into the guide hole 12 and cooperates with the guide hole 12, a rear end of the driving bar 42 is connected to a rear end of the piston rod 41, and a rack 421 is provided on the driving bar 42; a water injection driving wheel 5 is connected to the handle 1 and can rotate, and the water injection driving wheel 5 includes a gear 51, and the gear is meshed with the rack 421; the suction tube 3 is connected to the handle 1 and communicates with the suction hole 15; the suction tube closing structure 6 is connected to the handle 1 and can clamp the suction tube 3.

[0022] When the utility model is used, the cleaning head 2 is inserted into the clean water, and then the water injection structure 4 is pulled back, and the piston 44 moves backward so that the clean water is sucked into the liquid cavity 11; and the suction tube 3 is connected to the negative pressure suction device. When cleaning the oral cavity, the palm, middle finger, ring finger and little finger of one hand hold the handle 1, the thumb of the hand faces the water injection drive wheel 5, and the index finger faces the suction tube closing structure 6; then the oral cleaning care can be started. The cleaning head 2 is inserted into the oral cavity and the handle 1 is moved to brush the teeth. The thumb moves the water injection drive wheel 5, and the water injection drive wheel 5 drives the drive bar 42 forward through the engagement of the gear 51 and the rack 421, and then drives the piston rod 41 and the piston 44 forward, so that the clean water in the liquid cavity 11 can be pressed out to achieve flushing. The index finger operates the suction tube closing structure 6 to control the suction tube 3 switch, thereby controlling the water absorption. It can be seen that the utility model can realize various operations required for cleaning the oral cavity with a flushing and suction mouth protection sputum suction tube with one hand, and it is more convenient to use.

[0023] If the gear 51 is directly toggled by hand, the gear 51 can be driven to rotate, but the hand feeling is poor. Therefore, the utility model preferably includes two toggling wheels 52, which are coaxially arranged with the gear 51 and respectively located on both sides of the gear 51, and the diameter of the toggling wheel 52 is larger than the diameter of the gear 51. In this way, the finger contacts the toggling wheel 52 to toggle, which has a better hand feeling and improves the comfort of operation. In order to further toggle, it is preferred that the toggling wheel 52 has a pattern for increasing friction.

[0024] The diameter of the toggle wheel 52 is larger than the diameter of the gear 51, so that it is easy to ensure that the finger contacts the toggle wheel 52 instead of the gear 51. Since the toggle wheel 52 has a large diameter and needs to partially extend into the handle 1, a groove should be provided on the handle 1 to avoid the toggle wheel 52, and grooves are provided on both sides of the guide hole 12.

[0025] As mentioned above, when the utility model is used, the cleaning head 2 is first inserted into the cleaning water, and then the water injection structure 4 is pulled back, and the piston 44 moves back so that the cleaning water is sucked into the liquid chamber 11. This can be achieved by pulling back the piston rod 41. For greater convenience, the water injection structure 4 preferably includes a pull ring 43, which is located behind the piston rod 41 and the drive bar 42, and the piston rod 41 and the drive bar 42 are both connected to the pull ring 43. In this way, the pull ring 43 can be pulled back by holding it with a finger to achieve the backward movement of the piston 44, which is more convenient.

[0026] The specific arrangement of the suction tube 3 is preferably as follows: the rear end of the suction hole 15 is located in front of the liquid cavity 11 , the handle 1 has a suction tube hole 13 extending forward from the rear end of the handle 1 , the suction tube 3 passes through the suction tube hole 13 and is connected to the suction hole 15 .

[0027] The specific structure of the suction tube closing structure 6 is preferably: the suction tube closing structure 6 includes a pressing plate 61 and a pressing head 62 connected to the pressing plate 61, the pressing plate 61 is hinged to the handle 1, and when the pressing plate 61 is pressed, the pressing head 62 can press the suction tube 3 to close the suction tube 3. The suction tube 3 is the same as the prior art and is an elastic hose. When the suction tube 3 is not pressed, it opens naturally. When the pressing plate 61 is pressed, the pressing plate 61 swings, and the pressing head 62 presses the suction tube 3 to close the suction tube 3. Since the pressing head 62 is to press the suction tube 3 located in the handle 1, a hole for the pressing head 62 to pass through should be provided on the handle 1.

[0028] The guide hole 12 and the suction tube hole 13 should be located at both sides of the liquid chamber 11. This is to facilitate the above-mentioned operation: the palm, middle finger, ring finger and little finger hold the handle 1, the thumb turns the water injection drive wheel 5, and the index finger operates the suction tube closing structure 6.

[0029] As described in the background technology, the brush head and handle of the existing flushing and suction oral protection phlegm suction brush are arranged in the same direction. When cleaning the teeth on the left and right sides, it is necessary to change hands or reverse the operation, which is inconvenient. In order to solve this problem, the utility model preferably sets the cleaning head 2 to be perpendicular to the handle 1. When cleaning the teeth on the left and right sides, the handle 1 is moved left and right to move the brush head 2 left and right, and the part of the brush head 2 protruding from the handle 1 on the left and right extends into the deep sides of the patient's mouth to achieve oral cleaning, without the need for changing hands or reverse operation, which is more convenient.
