[0036] Among them, as Figure 2 and Figure 4 shown in the figure, a pulse mechanism 3 is provided on the cylinder cover 1. The pulse mechanism 3 includes a pulse component, a first driving component, and a connecting component;

[0037] The pulse component includes a connecting pipe 31 fixedly connected to the bottom end of the hose 210. A piston rod 32 is slidably connected to the inner wall of the connecting pipe 31. A fixing ring 35 is fixedly connected to the outer wall of the piston rod 32. A connecting sleeve 33 is slidably connected to the outer wall of the fixing ring 35. The bottom surface of the connecting sleeve 33 is fixedly connected to the inner bottom wall of the cylinder cover 1. A spring 34 is fixedly connected to the inner wall of the connecting sleeve 33. The left end of the spring 34 is fixedly connected to the right side of the fixing ring 35.

[0038] Among them, as Figure 2 and Figure 4 shown in the figure, the first driving component includes a U-shaped fixing plate 36 fixedly connected to the inner bottom wall of the cylinder cover 1. A third motor 37 is fixedly connected to the inner top wall of the U-shaped fixing plate 36. The output end of the third motor 37 is fixedly connected to a disturbing plate 38.

[0039] Among them, as Figure 4 shown, the connecting component includes a connecting plate 39 rotatably connected to the inner bottom wall of the cylinder cover 1. A fixing column 310 is fixedly connected to the top surface of the connecting plate 39. A first connecting shaft 311 is fixedly connected to the top surface of the connecting plate 39. A connecting rod 312 is rotatably connected to the outer wall of the first connecting shaft 311. One end of the connecting rod 312 away from the first connecting shaft 311 is hinged to one end of the piston rod 32 away from the connecting pipe 31.

[0040] By providing the pulse mechanism 3, when spraying water, the third motor 37 on the U-shaped fixing plate 36 is started, and the disturbing plate 38 will rotate. The disturbing plate 38 drives the connecting plate 39 to rotate through the fixing column 310. The connecting plate 39 pulls the piston rod 32 through the first connecting shaft 311 and the connecting rod 312. At this time, the fixing ring 35 on the piston rod 32 compresses the spring 34 and slides in the connecting sleeve 33. When the disturbing plate 38 rotates a certain angle, the spring 34 is released, and the disturbing plate 38 is separated from the fixing column 310. At this time, the piston rod 32 will slide quickly in the connecting pipe 31 once. The continuous rotation of the disturbing plate 38 will cause the piston rod 32 to slide quickly in the connecting pipe 31 at intervals, thereby pressing the water flow to cause a pulse effect. The setting of the pulse mechanism 3 can intermittently release high-pressure water flow, effectively flushing the plaque and food residues on the tooth surface, especially the stubborn dirt embedded deep in the tooth gaps, improving the cleaning effect of the cleaner. And compared with the continuous high-pressure water flow, the intermittent high-pressure water flow can reduce the water consumption while maintaining the cleaning effect, improving the environmental protection effect of the cleaner.

[0041] Among them, as Figure 2 and Figure 5 shown, a check mechanism 4 is provided on the cylinder cover 1;

[0042] The check mechanism 4 includes a check sleeve 41 fixedly connected to the bottom end of the connecting pipe 31. A sliding column 42 is slidably connected to the inner wall of the check sleeve 41. A first spring 43 is fixedly connected to the outer wall of the sliding column 42. A plurality of notches 44 are formed on the bottom surface of the sliding column 42.

[0043] By providing the check mechanism 4, the water flow can enter the inside of the check sleeve 41 from the notches 44, and then push open the sliding column 42 to compress the first spring 43 and then enter the connecting pipe 31. When the pulse mechanism 3 acts, the water flow in the connecting pipe 31 may also flow backward. At this time, the water flow presses against the sliding column 42 and cannot flow back. The setting of the check mechanism 4 can prevent the water flow from flowing backward and ensure the stability of the operation of the pulse mechanism.

[0044] Among them, as Figure 2 shown, a water storage cylinder 11 is fixedly connected to the bottom surface of the cylinder cover 1. A water suction pipe 12 is fixedly connected to the bottom end of the check sleeve 41.

[0045] By providing a water storage cylinder 11, water can be stored, facilitating the use of the cleaner. The bottom end of the check valve sleeve 41 is fixedly connected to a water suction pipe 12, which can suck the water in the water storage cylinder 11, enhancing the convenience of using the cleaner.

[0046] A specific application of this embodiment is as follows: When it is necessary to adjust the angle of the nozzle 29, the first motor 213 is started. The first worm 212 on the first support ear plate 211 rotates. The first worm 212 meshes with the first worm gear 23, driving the first sleeve 21 to rotate. Thus, the cylinder 22 can rotate. The second motor 217 on the fixed plate 216 is started, and the second worm 215 on the second support ear plate 214 rotates. The second worm 215 meshes with the second worm gear 25, driving the second sleeve 24 to rotate. The first bevel gear 26 at the top of the second sleeve 24 will also rotate accordingly. The first bevel gear 26 meshes with the second bevel gear 28, driving the connecting shaft 27 to rotate. At this time, the nozzle 29 can be adjusted according to the need. At the same time, the first limiting ring 218 and the second limiting ring 219 can limit the first sleeve 21, making its rotation smoother. The third limiting ring 220 and the first bevel gear 26 can limit the second sleeve 24, making its rotation smoother. The setting of the adjustment mechanism 2 can conveniently adjust the angle of the nozzle. When the user cleans different tooth parts, there is no need to frequently change the hand-held angle. The operation is simple. Especially when cleaning the teeth at the back of the oral cavity, it is more convenient, greatly increasing the convenience of using the oral care cleaner.

[0047] By providing a pulse mechanism 3, when spraying water, the third motor 37 on the C-shaped fixed plate 36 is started, and the disturbing plate 38 will rotate. The disturbing plate 38 drives the connecting plate 39 to rotate through the fixed column 310. The connecting plate 39 pulls the piston rod 32 through the first connecting shaft 311 and the connecting rod 312. At this time, the fixing ring 35 on the piston rod 32 compresses the spring 34 and slides in the connecting sleeve 33. When the disturbing plate 38 rotates a certain angle, the spring 34 is released, and the disturbing plate 38 separates from the fixed column 310. At this time, the piston rod 32 will slide quickly once in the connecting pipe 31. With the continuous rotation of the disturbing plate 38, the piston rod 32 will slide quickly in the connecting pipe 31 at intervals, thereby pressing the water flow to cause a pulsed effect. The setting of the pulse mechanism 3 can intermittently release high-pressure water flow, effectively flushing the plaque and food residues on the tooth surface, especially the stubborn dirt embedded deep in the tooth gaps, improving the cleaning effect of the cleaner. And compared with the continuous high-pressure water flow, the intermittent high-pressure water flow can reduce the water consumption while maintaining the cleaning effect, enhancing the environmental protection effect of the cleaner.

[0048] By providing the check mechanism 4, water can enter the inside of the check sleeve 41 from the notch 44, and then push open the slide column 42 to compress the first spring 43 to enter the connecting pipe 31. When the pulse mechanism 3 is in action, the water in the connecting pipe 31 may also flow back. At this time, the water cannot flow back against the slide column 42. The setting of the check mechanism 4 can prevent the water from flowing back and ensure the stability of the operation of the pulse mechanism 3.

[0049] By providing a water storage cylinder 11, water can be stored to facilitate the use of the cleaner. The bottom end of the check sleeve 41 is fixedly connected to a water suction pipe 12, which can absorb water in the water storage cylinder 11, thereby improving the convenience of using the cleaner.
