The turbulent flow device 2 is provided with a turbulent flow cavity 25 and a turbulent flow body 23 arranged in the turbulent flow cavity 25; the head end of the turbulent flow cavity 25 is communicated with the water outlet end 12 of the nozzle main body pipe 1, and the tail end of the turbulent flow cavity 25 is provided with a nozzle 13; the turbulent flow body 23 is fixedly or movably connected in the turbulent flow cavity 25, the head end of the turbulent flow body 23 faces the water outlet end 12, and the tail end of the turbulent flow body 23 faces the nozzle 13. A channel between the back side of the turbulent flow body 23 and the inner wall of the turbulent flow cavity 25 is a first side channel 251, a channel between the belly side of the turbulent flow body 23 and the inner wall of the turbulent flow cavity 25 is a second side channel 252, and the first side channel 251 and the second side channel 252 are parts of the turbulent flow cavity 25; the lengths of the first side flow channel 251 and the second side flow channel 252 are different, and there is a length difference between the two in the water flow direction, which may be that a curved path of the first side flow channel 251 in the water flow direction (i.e. the length of the first side flow channel 251 from the beginning to the end of the curve) is greater than that of the second side flow channel 252 (i.e. the length of the second side flow channel 252 from the beginning to the end of the curve), or that a curved path of the second side flow channel 252 in the water flow direction (i.e. the length of the second side flow channel 252 from the beginning to the end of the curve) is greater than that of the first side flow channel 251 (i.e. the length of the first side flow channel 251 from the beginning to the end of the curve). At least one of the first side flow passage 251 and the second side flow passage 252 is arranged along the head-to-tail direction variable cross section of the spoiler 23; in the embodiment shown in fig. 1 and 2, the first side flow channel 251 is arranged along the end-to-end direction of the spoiler 23 with a variable cross section, and the second side flow channel 252 is arranged along the end-to-end direction of the spoiler 23 with an equal cross section; of course, in other embodiments, the first side channel 251 may be disposed along the end-to-end direction of the spoiler 23 with an equal cross section, and the second side channel 252 may be disposed along the end-to-end direction of the spoiler 23 with a variable cross section; alternatively, the first side flow channel 251 and the second side flow channel 252 are arranged with variable cross sections along the head-to-tail direction of the spoiler 23.

In the tooth flushing device nozzle with the turbulence device 2, the turbulence device 2 is arranged at the water outlet end 12 of the nozzle main body pipe 1, the turbulence device 2 is provided with the turbulence containing cavity 25 and the turbulence body 23 arranged in the turbulence containing cavity 25, at least one of the first side flow channel 251 and the second side flow channel 252 between the turbulence body 23 and the inner wall of the turbulence containing cavity 25 is arranged in a variable cross section along the head-tail direction of the turbulence body 23, and the first side flow channel 251 and the second side flow channel 252 are asymmetrically arranged relative to the center line of the turbulence containing cavity. Thus, when the curved path of the first side flow channel 251 is larger than the curved path of the second side flow channel 252, or when the curved path of the first side flow channel 251 is smaller than the curved path of the second side flow channel 252, one path of liquid flowing through the first side flow channel 251 is longer, the other path of fluid flowing through the second side flow channel 252 is shorter, the two paths of fluid converge after flowing through the flow channels with different lengths, and because the water flow is incompressible fluid, and meanwhile, the speed difference occurs when the two paths flow through the paths with different lengths, the water pressure between the flow channels at two sides of the turbulent flow 23 is different, so that the turbulent flow 23 is deformed and swung due to the pressure difference between the upper and lower water pressures, the water flow is further disturbed to generate vortex and bubble, the water and the additive are fully mixed, and the efficacy exertion degree of the cleaning product is improved to a certain extent; the action of disturbing the fluid and beating the water can be presented visually, and the interest of tooth flushing is increased.

In the tooth flushing device nozzle with the flow disturbing device 2, water flow enters from the water inlet end 11 on the nozzle main body pipe 1 and flows into the flow disturbing cavity 25 from the water outlet end 12, and finally flows out from the nozzle 13 at the tail end of the flow disturbing cavity 25. As shown in fig. 1, a limiting protrusion 14 which is matched with the tooth flusher handle in a stopping manner is arranged on the nozzle main body pipe 1, and the limiting protrusion 14 is arranged at a position of the nozzle main body pipe 1 close to the water inlet end 11. As a preferred embodiment, as shown in fig. 2, the turbulent device 2 further includes an adapter cylinder 21 connected to the water outlet end 12 and a water outlet nozzle 22 connected to the rear portion of the adapter cylinder 21, the inner cavities of the adapter cylinder 21 and the water outlet nozzle 22 form a turbulent chamber 25, and the nozzle 13 is disposed at the rear end of the water outlet nozzle 22.

In the tooth flushing device nozzle with the flow disturbing device 2, when water flows through the flow disturbing cavity 25, the first side flow channel 251 and/or the second side flow channel 252 are arranged along the head-tail direction of the flow disturbing body 23 in a variable cross section manner, so that a length difference exists between the first side flow channel 251 and the second side flow channel 252 between the flow disturbing body 23 and the inner wall of the flow disturbing cavity 25, and the first side flow channel 251 and the second side flow channel 252 are asymmetrically arranged relative to the center line of the flow disturbing cavity 25. But also can lead colored or colorless mouthwash or other cleaning agents added into the turbulence containing cavity 25 to be fully fused with water, thereby increasing the interest of tooth washing and improving the efficiency and the exertion degree of the cleaning agents to a certain extent.

As before, when water flows through the baffle volume 25, the pressure difference across the baffle 23 causes the baffle 23 to oscillate. The turbulent flow body 23 may be made of one or more flexible materials, and in order to make the oscillating effect generated by the turbulent flow body 23 better, as a preferred embodiment, the turbulent flow body 23 is made of a flexible material, so that when the water flows through the turbulent flow cavity 25, the pressure difference between the two sides of the turbulent flow body 23 makes the turbulent flow body 23 made of the flexible material oscillate flexibly to enhance the water flow swirling effect. The swing amplitude of the tail 232 of the spoiler 23 is larger, and in order to make the tail 232 swing flexibly, as a preferred embodiment, the head 231 of the spoiler 23 and the tail 232 of the spoiler 23 are made of flexible materials with different hardness, and the hardness of the material of the head 231 of the spoiler 23 is larger than that of the material of the tail 232 of the spoiler 23, which is more beneficial to the tail 232 of the spoiler 23 to swing flexibly. Of course, the turbulent flow body 23 can be made of a single material, and the tail end of the turbulent flow body 23 is more easily deformed due to the smaller thickness than the head.

As shown in fig. 2, the head 231 of the spoiler 23 is connected to the inner sidewall of the spoiler housing 25 by a fixing rod 24, the fixing rod 24 is closer to the head end of the spoiler 23, the fixing rod 24 may be made of a hard material, and the spoiler 23 is inserted and sleeved on the fixing rod 24; the turbulent flow body 23 and the fixing rod 24 can also be molded into an integral structure and then are arranged on the side wall of the turbulent flow cavity 25; thus, the processing and the assembly are convenient. Fixed rod 24 may also be made of a flexible material, and fixed rod 24 made of a flexible material may make turbulent fluid 23 more susceptible to oscillation.

As shown in fig. 2, the cross-sectional dimension of the head 231 of the spoiler 23 is greater than the cross-sectional dimension of the tail 232 of the spoiler 23, the head 231 of the spoiler 23 is thicker, and the tail 232 of the spoiler 23 is thinner, so that the tail 232 of the spoiler is weaker than the head 231 due to the gradual thinning of the structure of the tail 232 of the spoiler relative to the structure of the head 231 thereof, and the spoiler 23 can be injection-molded with more than two soft materials in a split manner, so as to make the tail 232 of the spoiler easier to deform and swing. As a preferred embodiment, the turbulent flow 23 is a wing-shaped or bionic fish-shaped turbulent flow body, the wing-shaped or bionic fish-shaped turbulent flow body has a thicker head part and a thinner tail part, and the turbulent flow 23 in these shapes has a better swinging effect and generates a better vortex effect. In order to increase the turbulent flow effect of the turbulent flow body 23, comb teeth or salient points can be further arranged on the tail 232 of the turbulent flow body 23, so that turbulent flow elements are added, and the comb teeth (comb tooth-shaped structures) and the salient points can enhance the turbulent flow effect on water flow.

In order to facilitate the connection of the fixing rod 24 and the turbulence generating chamber 25, as a preferred embodiment, two opposite connecting grooves 3 are provided on the inner side wall of the turbulence generating chamber 25, and two ends of the fixing rod 24 are rotatably or fixedly connected in the connecting grooves 3. The connecting slot 3 is preferably open at the head end of the nozzle 22. As shown in fig. 3 and 4, which are schematic structural views of two different embodiments of the water outlet nozzle 22, as shown in fig. 3, the connecting groove 3 can be configured in a semi-cylindrical shape; as shown in fig. 4, the coupling groove 3 may be provided in a square groove shape.

As mentioned above, the turbulent fluid 23 is of an airfoil shape or a bionic fish shape, and is aimed at converging the first side channel 251 and the second side channel 252 of the turbulent fluid 23 when the liquid at the water outlet end 12 of the nozzle main body tube 1 flows into the turbulent flow cavity 25, and the lengths of the first side channel 251 and the second side channel 252 of the turbulent fluid 23 are different (the lengths of flow lines are different); because rivers are incompressible fluid, the velocity difference can appear in the runner route of different length of flowing through simultaneously to make the water pressure of disturbing fluid 23 back of the body both sides produce the pressure differential and arouse disturbing fluid 23 to warp and the swing, and then disturbance rivers produce the vortex, and disturbing fluid 23 can demonstrate the swing of different amplitude under the pulse rivers effect of the different gears of tooth ware shower nozzle, make multiple liquid mix more evenly and have visuality and enjoyment.

The spoiler 2 may be detachably mounted as a separate component to a variety of irrigators to fit the variety of irrigators. The mounting mode of the turbulent flow device 2 and the nozzle main body pipe 1 of the tooth flushing device comprises but is not limited to buckling, gluing, ultrasonic and secondary injection molding. The nozzle main body pipe 1 can be shortened, the turbulent fluid 23 is arranged in the nozzle main body pipe 1 with the inner diameter not changed greatly, the adapter cylinder 21 and the water outlet nozzle 22 for constructing the turbulent flow containing cavity 25 are omitted, and the integral attractiveness and the use comfort of the tooth flushing device are improved; the parts of the nozzle main body pipe 1 and the turbulence device 2 are made of engineering plastics and soft materials harmless to human bodies. The turbulence device 2 can also be made into a micro-container, which is used for dropping liquid or placing solid fragrance, mouthwash and liquid medicine with cleaning, maintenance and treatment functions, and the fragrance, the mouthwash and the liquid medicine can slowly release into water to enter the oral cavity along with the swing of the turbulence fluid 23.
