DETAILED DESCRIPTION
[0035] The technical solutions in the embodiments of the present application will be apparently and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the protection scope of the present application.
[0036] The present application will be further described below with reference to the drawings in the description.
[0037] With reference to the drawings in the description Figures 1-9 , the present application provides the following technical solutions: a water pick component 100, specifically, including an external shell 1 and a flow guide 2 placed in the external shell 1, the external shell 1 extends along an axial direction, in the embodiment, the external shell 1 is tubular, and a flow cavity 3 is formed inside the external shell 1. The external shell 1 has a water inlet 4 and a water outlet 5 at two ends, and the flow guide 2 is placed in the flow cavity 3. The flow guide 2 extends along the axial direction and includes a scattering part 6, a spiral guide part 7 and a gasification part 8, the scattering part 6 is close to the water inlet 4 side, the spiral guide part 7 is located downstream of the scattering part along the liquid flow direction, and the gasification part 8 is located downstream of the spiral guide part 7 along the liquid flow direction, the scattering part 6 has a cone part 9 radially outwardly expanded along the liquid flow direction from the water inlet 4 side, the spiral guide part 7 has guide blades 10 distributed in a spiral, and the gasification part 8 has gasification blades 11 arranged in a grid shape.
[0038] As shown in the drawings Figures 1-5As shown, the first preferred embodiment of the present application is shown, and in the embodiment, the outer shell 1 is a hollow tubular structure, and the flow cavity 3 is inside the tubular structure, and the flow guide 2 is arranged in the flow cavity 3. Specifically, the flow guide 2 has an axial base body 14, and the extension direction of the flow guide 2 is the same as the extension direction of the outer shell 1, and the two are coaxial. It should be noted that in the embodiment, the flow guide 2 can be fixed relative to the outer shell 1 or can rotate relative to the outer shell 1, and the relative relationship between the two should not be limited. Specifically, the two ends of the flow guide 2 can be arranged to be inserted into the inner wall of the outer shell 1, and the insertion mode can be relative rotation after insertion, or relative fixation after insertion. The water inlet 4 and the water outlet 5 are formed at the two ends of the outer shell 1, and the flow guide 2 is sequentially provided with the scattering part 6, the spiral guide part 7, and the gasification part 8 along the flow direction of the liquid, and in addition, the flow guide 2 has a tail end guide part 19 close to the water outlet.
[0039] The accompanying drawings will be described below. Figure 4 、 5 The structure of the flow guide 2 will be described in detail: the scattering part 6 is formed at one end of the flow guide 2 close to the water inlet 4, and in the embodiment, the scattering part 6 is arranged in a whole conical shape, and the cone is the taper part 9 of the scattering part 6. The taper part 9 is arranged to accelerate the outward diffusion of the fluid along the taper surface, reduce the resistance of the water flow, and more easily form a spiral water flow under the action of the spiral guide part 7. The structure of the scattering part 6 can be as shown in the embodiment, arranged in a whole conical shape, or only a conical section, that is, a combination of a cylindrical section and a conical section, or a combination of a conical section and a cylindrical section; or the taper part 9 of the scattering part 6 can be replaced by a hemispherical or spherical surface that expands outward along the water flow direction. As long as it has a surface that continuously expands outward along the water flow direction, it can basically achieve the desired technical effect.
[0040] The guide vanes 10 of the spiral guide part 7 are arranged in four pieces, each guide vane 10 is spirally extended, and is equally spaced along the outer periphery of the base body 14 of the flow guide 2. The adjacent guide vanes 10 form a guide flow channel 13. Specifically, each guide vane 10 is protruded from the surface of the base body 14 and is arranged to extend spirally from the water inlet 4 to the water outlet 5. That is, as shown in the enlarged view Figure 5 As shown, the guide vanes 10 of the spiral guide part 7 have a helical guide surface 15 that spirally extends. Of course, in specific implementation, the spiral guide part 7 can be provided with at least three guide vanes 10.
[0041] The vaporization section 8 is located at the end of the spiral guide section. Vaporization blades 11 of the vaporization section 8 are protruding from the axial base 11, and each vaporization blade 11 has a rhomboid cross-section along its axis. Each vaporization blade 11 has a blade back surface 16, defined as the end of the vaporization blade 11 that is relatively far from the base 14. A vortex guide surface 17 connects the blade back surface 16 and the base 14. The blade back surface 16 is a rhomboid surface, and two opposite sides of the rhombus correspond to the base 14 to form two opposing vortex guide surfaces 17. The rhomboid vaporization blades of the vaporization section 8 are formed as follows: multiple lines L are evenly spaced along the extension direction of a cylinder with a diameter larger than the axial base 14, and multiple lines N are defined at a certain angle to this extension direction. The L and N intersect at non-perpendicular angles to form multiple grid-like rhombuses. By retaining these rhombuses at intervals, the protruding rhomboid vaporization blades 11 shown in the figure are formed. A gasification channel 12 is formed between adjacent gasification blades 11 of the gasification section 8, and the gasification channel 12 extends spirally to form a spiral channel 18. The width of the gasification channel 12 is smaller than the width of the guide channel 13.
[0042] like Figure 3 As shown, the arrows indicate the flow direction of water between the vaporization blades 11. Based on the illustrated direction, in the two vortex guide surfaces of a vaporization blade 11, the upper vortex guide surface 17 is directly impacted by the water flow and extends along the flow direction. If the surface intersecting with this vortex guide surface 17 is defined as the natural processing surface, i.e., reference numeral 2 in the illustration is natural processing surface 2, in actual implementation, to reduce the resistance to water flow and ensure that the water flowing through the vortex guide surface 17 is a high-speed flow, the angle between the vortex guide surface 17 and the natural processing surface 2 is an acute angle. Because the water flow at the back surface 16 of the blade is relatively slow, when the slower-flowing water comes into contact with the high-speed flowing water, the pressure on the back surface 16 of the blade decreases, creating a vacuum state. This accelerates water vaporization, that is, it accelerates bubble formation.
[0043] The tail end guide 19 is close to the water outlet 5 side, the tail end guide 19 is spherical, specifically, the tail end guide 19 is located at the end of the gasification part 8, the tail end guide 19 is similar to a semi-sphere. The tail end guide 19 only needs to have a spherical surface as shown in the figure, so in actual implementation, the tail end guide 19 is not limited to a semi-sphere or smaller than a semi-sphere. When the water flow flows through the gasification part 8 and flows into the tail end guide 19, due to the decrease of the impact on the water flow, plus the increase of the water flow channel 9 (the water flow channel in the gasification part 8 is a relatively narrow channel formed between the gasification blades 11, and the channel in the tail end guide 19 is formed between the outer wall of the tail end guide 19 and the outer shell 1), the water flow will flow along the outer wall of the tail end guide 19, and this flow will make the water flow area smooth, and ensure that the bubbles formed when the water flow flows out of the tail end guide 19 will not break.
[0044] By Figure 2 It can be seen that the spiral guide part 7 and the gasification part 8 both have an axial base body 14, the diameter of the end of the scattering part 6 is the same as the diameter of the base body 14, and the diameter of the head of the tail end guide 19 is the same as the diameter of the base body 14. The end of the component of the oral irrigator close to the water inlet 4 is defined as the head, and it can be understood that the end of the component away from the water inlet 4 (i.e. close to the water outlet 5) is the tail end.
[0045] Preferably, the outer shell 1 forms a tapered connecting section 20 at the position corresponding to the scattering part 6, the aperture of the tapered connecting section 20 increases from the water inlet 4 to the water outlet 5. Similarly, the outer shell 1 can further form another tapered connecting section 20 at the position corresponding to the tail end guide 19, which cooperates with the tail end guide 19, and the aperture of the tapered connecting section 20 decreases from the water inlet 4 to the water outlet 5.
[0046] The principle of this invention is described below: During use, a large flow of water is injected (generally drawn in by a pump in a water flosser). The water flow is guided by the spiral guide surface 15 to generate a rotating water flow, entering the vaporization section. The vaporization blades in the vaporization section are also spirally arranged, causing the water flow to advance in a spiral state. The water flow reduces resistance by passing through the acute angle between the vortex guide surface 17 and the processed natural surface 2. When the water flows spirally to the back surface 16 of the blade, the water flow velocity at this location is relatively slow. Contact with the high-speed flowing water causes the pressure at the back surface 16 of the blade to decrease rapidly, accelerating the mixing and diffusion of the water flow and creating a vacuum state. This vacuum causes localized vaporization of the water flow, resulting in a large number of bubbles. The water flow is pressurized through the conical connecting section 20 at the corresponding tail guide section and passes through the outlet 5 carrying a large number of bubbles. The oral irrigator component of this invention can carry a large number of air bubbles in the water flow by using the guide member 2. The vaporized water flow can improve the oral cleaning effect through the cavitation principle. By forming a spiral surface on the inner wall of the outer shell 1 and cooperating with the guide member 2, the impact of the water flow is accelerated, which further accelerates the speed of water vaporization, ensuring that more air bubbles are formed in the water flow, and further improving the oral cleaning effect.
[0047] Furthermore, when the guide member 2 is rotatable relative to the outer casing 1, when water flows in from the inlet 4, the shaft (i.e., guide member 2) rotates through the spiral guide part 7. During the water flow, the continuous impact on the vortex guide surface further accelerates the rotation of the shaft (i.e., guide member 2). The shaft rotates in the same direction as the spiral guide part, thus slowing down the drop in water pressure and ensuring that the water pressure at the outlet 5 does not drop too much. The reduced aperture at the corresponding tail end guide further accelerates the water flow. During the rotation of the guide member 2, the velocity difference between the water flow and the flow on the back of the blades 16 increases, generating more bubbles. This water flow, when brushing teeth, achieves a better cleaning effect through the cavitation effect of numerous bubbles. This principle is somewhat similar to that of ultrasonic cleaning.
[0048] As attached Figures 6-7 The diagram shows a second preferred embodiment of the present invention. Specifically, unlike the first embodiment, in this embodiment, at least a portion of the inner wall of the outer housing 1 is a threaded segment 21 with threads or a helical surface. Specifically, threaded grooves or threaded teeth can be provided in the threaded segment 21. A threaded groove refers to a groove recessed into the inner wall of the outer housing 1 in a threaded shape, while a threaded tooth refers to a protruding threaded tooth provided on the inner wall of the outer housing 1. Both threaded grooves and threaded teeth can form a helical flow channel on the inner wall of the outer housing. The formation of this helical flow channel, in conjunction with the aeration section 8, can increase the impact of the water flow and form more bubbles.
[0049] Specifically, the thread segment 21 can be arranged to correspond to a part or all of the scattering portion 6, the spiral guide portion 7 or the vaporization portion 8. That is, the thread segment 21 can be formed only at a position corresponding to the scattering portion 6, only at a position corresponding to the spiral guide portion 7, or only at a position corresponding to the vaporization portion 8. The thread segment 21 can correspond to only a part of the scattering portion 6, the spiral guide portion 7 or the vaporization portion 8, or can correspond to all of the scattering portion 6, the spiral guide portion 7 or the vaporization portion 8.
[0050] In the present embodiment, the thread segment 21 is arranged to correspond to the vaporization portion. Specifically, as shown in the figure, in the present embodiment, the thread segment 21 is arranged with a thread groove 22, and the groove width of the thread groove 22 is smaller than the width of the vaporization blade 11. In the present application, the extension thickness of the vaporization blade 11 along the axial direction is defined as the width of the blade.
[0051] As shown in the figure, the third preferred embodiment of the present application is shown. Specifically, different from the first and second embodiments, in the present embodiment, the oral irrigator component further has a plurality of impellers 23, and the vaporization blades 11 are arranged in groups on each impeller 23, and the vaporization blades 11 on each impeller 23 are uniformly distributed along the outer periphery of the impeller 23. The impellers 23 are mounted on the flow guide 2. Figure 8 9 Specifically, the spiral guide portion 8 is arranged with a groove 25 connected with the impeller 23, and the impeller 23 is arranged with a protruding structure 26 snap-fitted with the groove 25. Similarly, the adjacent impellers 23 are also connected in a snap-fitted manner. The vaporization blade 11 can be integrally formed with the impeller 23, and the material of the vaporization blade 11 and the impeller 23 can be metal or plastic. The vaporization blade 11 can also be formed on the impeller 23 by secondary molding. In the present embodiment, the structure is arranged in a laminated manner, and each impeller is made into an independent component, which simplifies the overall processing technology. The independent impeller can be processed by plastic injection molding, ceramic powder injection molding, powder metallurgy die casting, CNC, etc. 9
