[0033] Figure 1 is a front view structural schematic diagram of a pipe body assembly shown in an embodiment of the present application, Figure 2 is a top view structural schematic diagram of a pipe body assembly shown in an embodiment of the present application. As Figure 1 and Figure 2 shown, the pipe body assembly includes a main body 11 and a gas filter 12. The main body 11 adopts a Venturi tube structure that first gradually contracts and then gradually expands. The main body specifically includes a contraction section 112, a throat 113, and a diffusion section 114 that are connected in sequence. Further, the main body 11 further includes an intake section 115. The intake section 115 is connected to the throat 113, and the gas filter 12 is disposed in the intake section 115.

[0034] The gas filter 12 can be, for example, a porous PE (polyethylene) sintered block, which can filter the high-pressure air generated by the air pump 22 to generate micron-sized bubbles, and then the filtered gas generates smaller nano-sized bubbles in the liquid.

[0035] As Figure 3 shown, the end of the contraction section 112 is connected to the water pump 21 for the liquid output by the water pump 21 to flow into the main body 11. The end of the intake section 115 is connected to the air pump 22 for the gas output by the air pump 22 to flow into the main body 11 after passing through the gas filter 12. Then, the liquid and the gas are mixed in the throat 113 and then flow out from the diffusion section 114. Thus, the liquid flowing out from the diffusion section 114 is nano-bubble water with extremely high decontamination ability, which can penetrate into the tooth gaps and oral blind spots, significantly improve the cleaning effect on the oral cavity, is convenient for users to directly use, and improves the usage convenience.

[0036] As one of the implementation manners, the main body 11 can be divided into a front pipe and a rear pipe. The front pipe includes an air inlet section 115, a contraction section 112, a throat section 113, and a diffusion section 114 that are connected in sequence. The rear pipe can be a tubular water inlet section. One end of the water inlet section is connected to the output end of the water pump 21, and the other end is ultrasonically welded to the contraction section 112 to form a Venturi tube. The water inlet section is used to extend the contraction section 112, which not only ensures the manufacturability of the mold process but also ensures the necessary sealing performance. Among them, the water inlet section and the contraction section 112 can also be integrally formed, and this is not the only limitation here.

[0037] As Figure 3 and Figure 4 As shown in the figure, as one of the implementation manners, the pipe body assembly further includes a threaded guide 13, and the threaded guide 13 is arranged in the cavity of the contraction section 112. Specifically, the threaded guide 13 is in a long strip threaded shape and is arranged in the cavity formed by the contraction section 112. When the liquid input by the water pump 21 into the main body 11 enters from the contraction section 112 and passes through the threaded guide 13, the flow direction of the water flow will change from a straight line to a spiral shape, which improves the shear force of the water flow on the bubbles.

[0038] As one of the implementation manners, a counterbore is provided at the air inlet of the air inlet section 115, and the gas filter 12 is arranged in the counterbore. Specifically, a counterbore is provided at the air inlet of the air inlet section 115 of the main body 11. By arranging the gas filter 12 in the counterbore, on the one hand, the gas filter 12 can be more firmly fixed on the air inlet section 115, thereby improving the connection stability and preventing the gas filter 12 from loosening or falling off. On the other hand, the gas filter 12 can be flush with the surface of the air inlet of the air inlet section 115, reducing the protrusion on the appearance and making the whole look more beautiful.

[0039] As one of the implementation manners, the air outlet of the air inlet section 115 is opened on the side wall of the throat section 113. Specifically, the air outlet of the air inlet section 115 can be opened in any area on the side wall of the throat section 113, thereby realizing the connection between the air inlet section 115 and the throat section 113. Preferably, the air inlet and the air outlet of the air inlet section 115 are coaxially arranged, and the air inlet section 115 can communicate with the throat section 113 at a preset angle. Among them, the preset angle can be, for example, 90°, and this is not limited here.

[0040] As one of the implementation manners, the air outlet of the air inlet section 115 is close to the end of the contraction section 112. Specifically, the flow velocity of the water flow is the most concentrated when it just enters the throat section 113 from the contraction section 112. By opening the air outlet of the air inlet end on the side wall of the throat section 113 close to the end of the contraction section 112, furthermore, the rapid water flow can shear the bubbles entering the throat section 113 from the air inlet section 115 into smaller nanoscale bubbles.

[0041] AsFigure 3 , Figure 5 and Figure 6 As shown in Figure 3 , Figure 5 and Figure 6 , as one of the embodiments, the present application also provides a dental irrigator, which includes a water pump 21, an air pump 22, a nozzle 23 and the tube assembly as described above.

[0042] As Figure 7 shown, as one of the embodiments, the output end of the water pump 21 is communicated with the contraction section 112, the air pump 22 is communicated with the air inlet of the intake section 115, and the nozzle 23 is communicated with the diffusion section 114. Among them, the water pump 21 is used to transport the liquid from the contraction section 112 to the main body 11, and mix with the high-pressure gas input by the air pump 22 from the intake section 115 when passing through the throat 113 to form nano-bubble water. The nano-bubble water continues to pass through the diffusion section 114 and the nozzle 23 in sequence under the drive of the water pump 21 and then sprays outwards to form a cleaning water flow with nano-bubbles for the user to use. The nano-bubble water can penetrate into the tooth gaps and oral blind areas, effectively remove food residues and dental plaque, and improve the oral cleaning effect.

[0043] As Figure 8 , Figure 9 and Figure 10 shown, as one of the embodiments, the nozzle 23 is connected to the diffusion section 114 and is used to extend the diffusion section 114. Furthermore, it can achieve sufficient mixing of water and gas in the path of spraying outwards.

[0044] As Figure 3 , Figure 5 and Figure 6 shown, as one of the embodiments, the dental irrigator further includes a water pump housing 24, and the water pump 21 and the tube assembly are arranged inside the water pump housing 24. Specifically, the output end of the water pump 21 is located directly above the water pump 21, and the contraction section 112 of the main body 11 is arranged on the output end of the water pump 21. In this way, the tube assembly is arranged on the water pump 21 in a form where its length direction is parallel to the axis of the water pump housing 24. The water pump housing 24 covers the water pump 21 and the tube assembly, and is used to achieve the effects of protection and sealing.

[0045] As one of the embodiments, the dental irrigator further includes a shock absorber 26, and the air pump 22 is arranged on the water pump housing 24 through the shock absorber 26. Specifically, a buckle structure can be arranged on the air pump 22, and an installation groove corresponding to the buckle structure can be arranged on the water pump housing 24. By matching the buckle structure with the installation groove, the air pump 22 can be fixed on the water pump housing 24. By arranging the shock absorber 26 between the water pump housing 24 and the air pump 22, the noise generated by the air pump 22 during operation can be effectively reduced, and the user experience can be improved. As one of the embodiments, the water pump housing 24 includes an upper housing and a lower housing, and the shock absorber 26 and the buckle structure of the air pump 22 are both arranged on the lower housing.

[0046] Among them, the shock absorber 26 can be made of materials such as rubber, foam, PU (polyurethane), EVA (ethylene-vinyl acetate copolymer), etc., which is not limited herein.

[0047] As one of the implementation manners, the oral irrigator further includes a connecting pipe 27. One end of the connecting pipe 27 is connected to the output end of the air pump 22, and the other end is connected to the air inlet of the air inlet section 115, so that the air pump 22 guides air to the air inlet section 115.

[0048] Such as Figure 5 、 Figure 6 and Figure 7 As shown, as one of the implementation manners, the oral irrigator further includes a nozzle fixing bracket 28. The nozzle fixing bracket 28 can be arranged on the diffusion section 114 through a snap structure, for example. A receiving hole can be opened on the nozzle fixing bracket 28, and the nozzle 23 is detachably arranged in the nozzle fixing bracket 28 through the receiving hole to achieve the purpose of communicating with the diffusion section 114.

[0049] Such as Figure 7 As shown, as one of the implementation manners, the pipe body assembly further includes a first seal 14 and a second seal 15. In the illustrated structure, a first seal groove is opened at a position on the outer surface of the main body 11 corresponding to the contraction section 112 near the output end of the water pump 21, and a second seal groove is opened around the counterbore at the air inlet of the air inlet section 115.

[0050] The first seal 14 is arranged in the first seal groove for sealing between the water pump 21 and the contraction section 112, and further, improving the liquid tightness of the liquid input from the water pump 21 during the process of flowing into the contraction section 112.

[0051] The second seal 15 is arranged in the second seal groove for sealing between the water pump housing 24 and the air inlet section 115, and further, improving the gas tightness of the gas input from the air pump 22 during the process of entering the air inlet section 115.

[0052] As one of the implementation manners, the oral irrigator further includes a central control module 25. The central control module 25 is arranged on the water pump housing 24 for controlling and displaying the operating states of the water pump 21 and the air pump 22. Specifically, the central control module 25 can be a circuit board, for example. As a control device, the central control module 25 can be fixed on the water pump housing 24 through fasteners, for example, for controlling the operating states of the water pump 21 and the air pump 22 and the display of the status lights. Among them, the central control module 25 can be arranged on the other side of the water pump housing 24 relative to the air inlet section 115 to avoid physical interference with the air pump 22.

[0053] As one of the implementation manners, the water pump housing 24 has opposite first and second outer sides. The water pump 21 further includes a power source which is arranged on the first outer side and corresponds to the installation position of the water pump 21. The central control module 25 is arranged on the first outer side at an interval from the power source along the height direction of the water pump housing 24 and corresponds to the installation position of the main body 11. The air pump 22 is arranged on the second outer side corresponding to the water pump 21, and the air outlet end of the air pump 22 is connected to the air inlet section 115 of the main body 11 through a connecting pipe 27.

[0054] In the technical solution of the present application, by arranging a gas filter element in the air inlet section, the gas passing through the gas filter element can be mixed with the liquid flowing in from the contraction section at the throat. Furthermore, the liquid flowing out from the diffusion section is nano-bubble water with extremely high decontamination ability, which can penetrate into the tooth gaps and oral blind areas, improving the cleaning effect on the oral cavity.
