[0057] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0058] Reference below Figure 1-Figure 19 The flow guide device 1 according to the embodiment of the present application is described. The flow guide device 1 according to the embodiment of the present application can be connected to the water outlet of other water channel equipment such as a water heater, a wall-mounted boiler, a dishwasher, etc., to generate bubbles in the outlet water and adjust the flow rate of the outlet water.

[0059] like Figure 6 and Fig.16 As shown, the flow guide device 1 has a first flow channel 1a and a second flow channel 1b, and the first flow channel 1a and the second flow channel 1b are both arranged between the water inlet end and the water outlet end of the flow guide device 1 to guide the water flow from the water inlet end to the water outlet end. The flow guide device 1 includes a flow guide portion 10 and a regulating portion 20, and the first flow channel 1a is arranged in the flow guide portion 10, and the first flow channel 1a penetrates the flow guide portion 10 in the axial direction of the flow guide portion 10.

[0060] In one example, if Figure 6 and Fig.16 As shown, the upper end of the guide part 10 forms a water inlet end, and the lower end of the guide part 10 forms a water outlet end. There can be multiple first flow channels 1a, and the first flow channels 1a extend from the upper end surface of the guide part 10 to the lower end surface of the guide part 10 to penetrate the guide part 10 in the axial direction of the guide part 10. Among them, the first flow channels 1a can be arranged in the vertical direction, and can also be arranged in a direction inclined relative to the vertical direction.

[0061] Further, the regulating part 20 is sleeved on the periphery of the guide part 10, and the regulating part 20 is movable relative to the guide part 10 in the axial direction to open or close the second flow channel 1b. It can be understood that since the regulating part 20 is sleeved on the periphery of the guide part 10, the regulating part 20 does not have a blocking effect on the first flow channel 1a on the guide part 10, so the first flow channel 1a is always in an open state, and the water flow can always flow from the water inlet end of the guide part 10 to the water outlet end through the first flow channel 1a. In this way, when the regulating part 20 closes the second flow channel 1b, the water flow only flows from the water inlet end of the guide part 10 to the water outlet end through the first flow channel 1a; when the regulating part 20 opens the second flow channel 1b, the water flow can flow from the water inlet end of the guide part 10 to the water outlet end through the first flow channel 1a and the second flow channel 1b at the same time, thereby increasing the flow area of ​​the water flow passing through the guide part 10. Therefore, the water outflow rate of the guide portion 10 can be adjusted by controlling the adjustment portion 20 to open or close the second flow channel 1 b.

[0062] In an example, the adjusting portion 20 can move relative to the air guiding portion 10 along the axial direction of the air guiding portion 10 (ie, the up and down direction in the figure).

[0063] For example, Figure 2 and Figure 3 As shown, when the regulating part 20 is located at the position of closing the second flow channel 1b, the regulating part 20 blocks the water inlet end of the second flow channel 1b so that the water flow cannot enter the second flow channel 1b; Figure 4 and Figure 5 As shown, the regulating part 20 moves upward relative to the guide part 10 so that the regulating part 20 is located at a position to open the second flow channel 1b. At this time, the regulating part 20 is spaced apart from the water inlet end of the second flow channel 1b so that water can enter the second flow channel 1b.

[0064] For example, Fig.12 and Fig.13 As shown, when the regulating part 20 is located at the position of closing the second flow channel 1b, the regulating part 20 closes the water inlet end of the second flow channel 1b so that the water flow cannot enter the second flow channel 1b; Fig.14 and Fig.15 As shown, the regulating part 20 moves downward relative to the guide part 10, so that the regulating part 20 is located at a position to open the second flow channel 1b, and at this time, the regulating part 20 avoids the water inlet end of the second flow channel 1b, so that water can enter the second flow channel 1b. The upper end of the second flow channel 1b forms the water inlet end of the second flow channel 1b, and the lower end of the second flow channel 1b forms the water outlet end of the second flow channel 1b.

[0065] Furthermore, the first flow channel 1 a is used to generate bubbles in the water flow passing therethrough, and thus, the flow guiding device 1 according to the embodiment of the present application can be used as a bubble generator.

[0066] In one embodiment, if Figure 6 As shown, the first flow channel 1 a may be constructed as a Venturi structure.

[0067] Specifically, the first flow channel 1a includes a contraction section 101, a transition section 102 and an expansion section 103 which are sequentially connected in the extension direction thereof (i.e., the direction from top to bottom in the figure). Among them, in the direction from top to bottom, the diameter of the contraction section 101 gradually decreases, the diameter of the transition section 102 remains unchanged, and the diameter of the expansion section 103 gradually increases. It can be understood that in the process of water flow passing through the contraction section 101, due to the gradual decrease in the cross-sectional area of ​​the contraction section 101, the flow rate of the water flow gradually increases, and the pressure of the water flow gradually decreases, the air dissolved in the water flow is precipitated and a large number of bubbles are formed; in the process of water flow passing through the expansion section 103, due to the gradual increase in the cross-sectional area of ​​the expansion section 103, the flow rate of the water flow gradually decreases, and the pressure of the water flow gradually increases, the bubbles are fragmented, thereby forming a large number of micro bubbles. As a result, the number of bubbles in the water flow flowing out through the first flow channel 1a is large and the diameter is small, which is conducive to improving the bubble generation effect.

[0068] Preferably, the diameter of the transition section 102 is 0.6-0.8 mm. It should be noted that by setting the diameter of the transition section 102 to 0.6-0.8 mm, a large number of micro-nano bubbles with a diameter of 0.1-50 μm can be formed in the water flow flowing out through the first flow channel 1a, so that the flow guide device 1 forms micro-nano bubble water. It can be understood that if the diameter of the transition section 102 is small, the water flow rate passing through the first flow channel 1a per unit time is small; if the diameter of the transition section 102 is too large, the bubble generation effect will be poor. In order to ensure both the water flow rate through the first flow channel 1a and the bubble generation effect, the diameter of the transition section 102 of the first flow channel 1a is suitable for being set within the range of 0.6-0.8 mm.

[0069] Optionally, the diameter of the second flow channel 1b remains unchanged in its extension direction, that is, the second flow channel 1b will not generate bubbles for the water flowing through it. In this way, when the regulating part 20 closes the second flow channel 1b, the water flows out only through the first flow channel 1a, and the flow rate of the water flowing out of the water outlet end of the guide part 10 is small, but the density of bubbles in the water flow is relatively large; when the regulating part 20 opens the second flow channel 1b, the water can flow out through the first flow channel 1a and the second flow channel 1b at the same time, and the flow rate of the water flowing out of the water outlet end of the guide part 10 is large, but the density of bubbles in the water flow is relatively small. In this way, the guide device 1 can have two different water flow output modes to meet different usage requirements.

[0070] According to the flow guide device 1 of the embodiment of the present application, by providing a first flow channel 1a that can generate bubbles in the water flow on the flow guide portion 10, the flow guide device 1 has the function of generating bubbles in the water flow, and by providing an adjustment portion 20 that moves relative to the flow guide portion 10 to open or close the second flow channel 1b, the water flow can flow out only through the first flow channel 1a or through the first flow channel 1a and the second flow channel 1b at the same time, so that the flow guide device 1 has the function of regulating the flow rate. Therefore, the flow guide device 1 of the embodiment of the present application solves the technical problem that the bubble generator in the related art has a single function and does not have a flow regulation function. Therefore, the flow guide device 1 of the embodiment of the present application has both the function of generating bubbles and the function of regulating the water flow rate, thereby improving the scope of application of the flow guide device 1 and meeting the various usage requirements of users.

[0071] It should be noted that, in the implementation of the flow guide device 1 of the embodiment of the present application, the arrangement of the second flow channel 1 b may be defined by the flow guide portion 10 alone, or may be defined by the flow guide portion 10 and the adjustment portion 20 together.

[0072] In one embodiment, if Figure 1-7 As shown, the second flow channel 1b is defined by the guide part 10 alone. Specifically, the guide part 10 is provided with an annular boss 12 located below the regulating part 20, and the annular boss 12 is formed by extending outward from the outer peripheral wall of the guide part 10. The second flow channel 1b is provided on the annular boss 12 and penetrates the annular boss 12 in the up and down directions. Therefore, by controlling the relative movement of the regulating part 20 to the guide part 10, the lower end face of the regulating part 20 can be abutted or separated from the upper end face of the annular boss 12. Among them, when the lower end face of the regulating part 20 abuts against the upper end face of the annular boss 12, the lower end face of the annular boss 12 blocks the water inlet end of the second flow channel 1b, so that the second flow channel 1b is in a closed state; when the lower end face of the regulating part 20 is separated from the upper end face of the annular boss 12, the lower end face of the annular boss 12 avoids the water inlet end of the second flow channel 1b, so that the second flow channel 1b is in an open state.

[0073] In one embodiment, if Figure 12-Figure 17As shown, the second flow channel 1b is defined by the guide part 10 and the regulating part 20. Specifically, the regulating part 20 is provided with a stop boss 22, which is formed by the lower end of the regulating part 20 extending in the direction toward the central axis of the regulating part 20, and the second flow channel 1b is defined between the inner peripheral wall of the stop boss 22 and the outer peripheral wall of the regulating part 20. Further, the guide part 10 is provided with an annular boss 12 located above the stop boss 22, which is formed by the outer peripheral wall of the guide part 10 extending outward. Therefore, by controlling the relative movement of the regulating part 20 to the guide part 10, the lower end surface of the annular boss 12 can be abutted or separated from the upper end surface of the stop boss 22. Among them, when the lower end surface of the annular boss 12 abuts against the upper end surface of the stop boss 22, the lower end surface of the annular boss 12 blocks the water inlet end of the second flow channel 1b, so that the second flow channel 1b is in a closed state; when the lower end surface of the annular boss 12 separates from the upper end surface of the stop boss 22, the lower end surface of the annular boss 12 avoids the water inlet end of the second flow channel 1b, so that the second flow channel 1b is in an open state.

[0074] In one embodiment, one of the adjusting part 20 and the guide part 10 is provided with a guide groove 21 extending in a spiral along the axial direction of the adjusting part 20 or the guide part 10, and the other is provided with a guide part 11 slidably matched with the guide groove 21. That is, the adjusting part 20 may be provided with a guide groove 21, and the guide part 10 may be provided with a guide part 11 matched with the guide groove 21; or, the guide part 10 may be provided with a guide groove 21, and the adjusting part 20 may be provided with a guide part 11 matched with the guide groove 21. When the adjusting part 20 and the guide part 10 rotate relative to each other, the guide part 11 slides along the guide groove 21, and because the guide groove 21 extends in a spiral in an upward or downward direction, the guide part 11 can make the adjusting part 20 or the guide part 10 relatively displace upward or downward under the guidance of the guide groove 21. In this way, by controlling one of the regulating part 20 and the guide part 10 to rotate relative to the other, the regulating part 20 and the guide part 10 can be made to move relative to each other in the axial direction, so that the regulating part 20 opens or closes the second flow channel 1b, thereby facilitating the adjustment of the flow of the guide device 1.

[0075] In one embodiment, if Figure 6-Figure 8 as well as Figure 16-Figure 18 As shown, the guide groove 21 is provided in the wall of the adjusting portion 20 and penetrates the wall in the thickness direction of the wall. The guide portion 11 is provided in the guide portion 10 and extends from the outer peripheral wall of the adjusting portion 20 to the guide groove 21 .

[0076] The guide groove 21 can extend spirally from top to bottom as shown in the figure, or can extend spirally from bottom to top as shown in the figure. Figure 8 and Fig.18In the example shown, the guide groove 21 can be formed by spirally extending from bottom to top on the wall of the adjusting portion 20. In this way, when the guide portion 10 rotates clockwise relative to the adjusting portion 20, the adjusting portion 20 moves downward relative to the guide portion 10, so that the adjusting portion 20 can be moved to a position to close the second flow channel 1b; when the guide portion 10 rotates counterclockwise relative to the adjusting portion 20, the adjusting portion 20 moves upward relative to the guide portion 10, so that the adjusting portion 20 can be moved to a position to open the second flow channel 1b. It can be understood that if the guide groove 21 is formed by spirally extending from top to bottom, when the guide portion 10 rotates clockwise relative to the adjusting portion 20, the adjusting portion 20 moves upward relative to the guide portion 10; when the guide portion 10 rotates counterclockwise relative to the adjusting portion 20, the adjusting portion 20 moves downward relative to the guide portion 10.

[0077] In one example, two guide grooves 21 may be symmetrically arranged about the central axis of the adjusting portion 20, and two guide portions 11 may be arranged one-to-one corresponding to the two guide grooves 21. The size of the guide groove 21 in the circumferential direction of the adjusting portion 20 is less than or equal to one-half of the circumferential size of the adjusting portion 20, and the two guide portions 11 are symmetrically arranged about the central axis of the guide portion 10. As a result, the cooperation between the guide portion 11 and the guide groove 21 is more reliable, and the relative movement between the guide portion 10 and the adjusting portion 20 is more stable.

[0078] In one embodiment, if Figure 1-Figure 5 as well as Figure 11-Figure 15 As shown, the flow guide device 1 further includes a sleeve 30 and a positioning joint 40. Specifically, the adjusting portion 20 and the flow guide portion 10 are both arranged in the sleeve 30, and the positioning joint 40 is rotatably matched with the sleeve 30. Among them, one of the adjusting portion 20 and the flow guide portion 10 forms a first rotating body with the sleeve 30, and the other forms a second rotating body with the positioning joint 40.

[0079] In one example, the positioning joint 40 is installed on the upper end of the sleeve 30 through the cover 50, the cover 50 and the sleeve 30 are fixedly connected by threads, at least part of the positioning joint 40 extends upward from the cover 50, and the part of the positioning joint 40 extending upward from the cover 50 can be fixedly connected to the external water outlet pipe. One of the adjustment part 20 and the diversion part 10 is positioned and matched with the sleeve 30, and the other is positioned and matched with the positioning joint 40. Among them, a sealing ring 90 can be set between the cover 50 and the sleeve 30 and between the cover 50 and the positioning joint 40 to improve the sealing of the diversion device 1.

[0080] It should be noted that the cover 50 and the positioning joint 40 can rotate relative to each other, so that one of the regulating part 20 and the flow guide part 10, the sleeve 30 and the cover 50 form a first rotating body, and the other of the regulating part 20 and the flow guide part 10 and the positioning joint 40 form a second rotating body. By rotating the sleeve 30, the first rotating body can be rotated relative to the second rotating body, so that the regulating part 20 and the flow guide part 10 rotate relative to each other, and then the regulating part 20 and the flow guide part 10 move relative to each other in the axial direction. Therefore, the regulating part 20 can open or close the second flow channel 1b by rotating the sleeve 30, so that the flow guide device 1 is more convenient for adjusting the water flow rate.

[0081] In one embodiment, if Figure 1-Figure 5 As shown, the sleeve 30 is positioned and matched with the guide part 10, and the positioning joint 40 is positioned and matched with the adjustment part 20. The guide part 10, the sleeve 30 and the cover 50 form a first rotating body, and the adjustment part 20 and the positioning joint 40 form a second rotating body, and the first rotating body and the second rotating body can rotate relative to each other.

[0082] Optionally, the inner peripheral wall of the sleeve 30 is provided with a support boss 31 extending toward the central axis thereof. The guide portion 10 is supported on the support boss 31, wherein one of the support boss 31 and the guide portion 10 is provided with a fixing groove 31a, and the other is provided with a fixing protrusion 31b matched with the fixing groove 31a.

[0083] In one example, the guide portion 10 is provided with an annular boss 12 located below the regulating portion 20, and the annular boss 12 is supported on the supporting boss 31. Specifically, the annular boss 12 is formed by extending outward from the outer peripheral wall of the guide portion 10, and the second flow channel 1b is provided on the annular boss 12 and penetrates the annular boss 12 in the up-down direction. Figure 5 As shown, the fixing protrusion 31b is formed by the lower surface of the annular boss 12 protruding downward. Fig. 9 As shown, the fixing groove 31a is formed by the upper surface of the supporting boss 31 being depressed downward, and the fixing protrusion 31b is clamped in the fixing groove 31a. Thus, the air guide 10 and the sleeve 30 form a positioning fit, so that the sleeve 30 can drive the air guide 10 to rotate together.
