[0017] Therefore, the utility model provides the following effects and / or advantages:

[0018] 1. The present application sets a blade water outlet structure with a rectifying part, so that after the water flow is input into the water inlet channel to the water inlet area, the water flow is blocked by the water retaining part, turns outward and flows through the slow flow area, then turns inward to the water outlet area, and finally turns forward to enter the water outlet channel and output high-pressure blade water through the blade water jet hole. Thus, the rectifying part allows the water flow to pass through the slow flow effect of three turns, inner and outer, outer and front, before entering the water outlet channel of the blade water outlet structure, which can mitigate the flow rate of the high-speed water flow input into the water inlet channel, improve the water splash effect of the high-pressure blade water output by the blade water jet hole at the outlet end of the subsequent water outlet channel, avoid the blade water splash in the form of a spray, and improve the stability of the blade water output by the blade water outlet structure, so as to improve the user experience. In addition, the rectifying part is simple to assemble and has low cost, which improves the economic benefits while ensuring the stability of the water splash, and has a very high cost performance.

[0019] 2. The water outlet and the water retaining part of the present application are plugged into the water inlet end of the water outlet channel through a plurality of connecting parts, the water inlet part is arranged against the outer end of the water inlet end of the water outlet channel, the water inlet part, the plurality of connecting parts and the water retaining part are enclosed to form a water inlet area, the water outlet, the plurality of connecting parts and the water retaining part are enclosed to form a water outlet area, and the water retaining part, the plurality of connecting parts and the water outlet channel are enclosed to form a slow flow area. Thus, under the premise of ensuring the slow flow effect of the water inlet area, the water outlet area and the slow flow area, the water outlet, the water retaining part and the water inlet are connected by a plurality of connecting parts, so as to achieve the effect of hollowing out the outer wall of the rectifying part to reduce the overall manufacturing cost, improve the practicality of the rectifying part, and further reduce the overall cost of the blade water outlet structure while ensuring the stability of the blade water outlet.

[0020] 3. The present application can facilitate the insertion of the rectifying component into the water inlet end of the water outlet channel through the inclined guiding of several mounting parts, and can stably insert the rectifying component into the water outlet channel through the interference fit between several abutting parts and the water outlet channel. At the same time, by setting the outer diameter of the water inlet part to be larger than the water inlet end of the water outlet channel, it is convenient to pull the rectifying component outward to separate it from the water outlet channel.

[0021] 4. The inner diameter of the water outlet of the present application gradually increases in the direction away from the water retaining part. Thus, the water outlet area of ​​the water outlet is increased, so that most of the water that first turns outward to the water inlet area and flows through the slow flow area turns inward to the water outlet area and then turns forward to the water outlet hole to discharge water. Only a very small amount of water in the slow flow area directly enters the water outlet channel along the gap between the several installation parts and the water outlet part and the water inlet end of the water outlet channel. The influence of the very small amount of water on most of the water after the slow flow effect of the rectifying part is so low that it can be ignored.

[0022] 5. The outlet end of the water outlet channel of the present application is arc-shaped and retracted to form a buffer portion connected to the water inlet end of the blade water jet hole. Therefore, before the water flows through the water outlet channel to the blade water jet hole after the water flow passes through the slow flow effect of the rectifying component, it first flows slowly through the buffer portion before outputting high-pressure blade water from the blade water jet hole, further improving the slow flow effect of the overall blade water outlet structure, ensuring the stability of the blade water splash, and avoiding the generation of spray.

[0023] 6. The present invention has several blade water outlet structures arranged in annular intervals, and several blade water injection holes are arranged in parallel and on different planes. Thus, the blade water outputted by the blade water injection holes of the several blade water outlet structures is parallel and on different planes, avoiding the overlapping and collision of several blade water to produce water mist, ensuring the stability of the blade water splash, and further improving the water outlet stability of several blade water.

[0024] It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the accompanying drawings:

[0033] refer to Figure 1-7 , a high-stability blade water outlet device, comprising:

[0034] The water outlet body 1 has a water inlet channel 2 extending to the inside through the water inlet end. Specifically, the water outlet body 1 can be a body of a water outlet device such as a nozzle;

[0035] A plurality of blade water outlet structures are arranged in the water outlet end of the water outlet body 1, each of the blade water outlet structures includes a water outlet channel 3 whose water inlet end is connected to the water outlet end of the water inlet channel 2, a rectifying member 4 detachably arranged in the water inlet end of the water outlet channel 3, and a blade water injection hole 5 connected to the water outlet end of the water outlet channel 3 and flatly penetrating the water outlet end of the water outlet body 1. The water inlet end and the water outlet end of the rectifying member 4 are penetrated by a water inlet area 41 and a water outlet area 42 respectively connecting the water inlet channel 2 and the water outlet channel 3. The rectifying member 4 includes a water retaining portion 43 disposed between the water inlet area 41 and the water outlet area 42, and a slow flow area 44 disposed outside the water retaining portion 43 and connecting the water inlet area 41 and the water outlet area 42.

[0036] The above structure is provided with a blade water outlet structure with a rectifying part 4, so that after the water flow is input into the water inlet channel 2 to the water inlet area 41, the water flow is blocked by the water retaining part 43, turns outward, flows through the slow flow area 44, then turns inward to the water outlet area 42, and finally turns forward to enter the water outlet channel 3 and outputs high-pressure blade water through the blade water injection hole 5. Thus, the rectifying part 4 makes the water flow go through the slow flow effect of three turns, namely, the inner and outer turns, the outer turns and the front turns, and then enters the water outlet channel 3 of the blade water outlet structure, which can mitigate the flow rate of the high-speed water flow input into the water inlet channel 2, improve the water splash effect of the high-pressure blade water output by the blade water injection hole 5 at the outlet end of the subsequent water outlet channel 3, avoid the blade water splash in the form of a spray, improve the stability of the blade water output by the blade water outlet structure, and improve the user experience. In addition, the rectifying part 4 is simple to assemble and has low cost, which improves the economic benefits while ensuring the stability of the water splash, and has a very high cost performance.

[0037] In order to ensure the slow-flow effect of the rectifying member 4 and reduce the overall cost of the rectifying member 4, the outer wall of the rectifying member 4 can be hollowed out so that the outer wall of the water retaining portion 43 and the inner wall of the water outlet channel 3 are spaced to form a slow-flow area 44 connecting the water inlet area 41 and the water outlet area 42, so as to reduce the manufacturing cost of the rectifying member 4. Specifically, the ends of the water inlet end and the water outlet end of the rectifying member 4 are respectively set as a water inlet portion 45 and a water outlet portion 46 including a water inlet hole 451 and a water outlet hole 461. The water inlet portion 45 and the water outlet portion 46 are connected by a plurality of connecting portions 47 arranged at intervals in annular shapes. The water retaining portion 43 is provided with a slow-flow area 44 for connecting the water inlet area 41 and the water outlet area 42. A plurality of connecting portions 47 are fixedly connected to the outer periphery between the water inlet hole 451 and the water outlet hole 461, the water outlet portion 46 and the water retaining portion 43 are plugged in the water inlet end of the water outlet channel 3 through the plurality of connecting portions 47, the water inlet portion 45 is disposed against the outer end portion of the water inlet end of the water outlet channel 3, the water inlet portion 45, the plurality of connecting portions 47 and the water retaining portion 43 form the water inlet area 41, the water outlet portion 46, the plurality of connecting portions 47 and the water retaining portion 43 form the water outlet area 42, the water retaining portion 43, the plurality of connecting portions 47 and the water outlet channel 3 form the slow flow area 44. Therefore, under the premise of ensuring the slow flow effect of the water inlet area 41, the water outlet area 42 and the slow flow area 44, the water outlet part 46, the water retaining part 43 and the water inlet part 45 are connected by a plurality of connecting parts 47, so that the outer wall of the rectifying part 4 is hollowed out to reduce the overall manufacturing cost, thereby improving the practicality of the rectifying part 4, and further reducing the overall cost of the blade water outlet structure while ensuring the stability of the blade water outlet.

[0038] In order to improve the convenience of disassembly and assembly of the rectifying part 4, the water inlet part 45, the water retaining part 43, and the water outlet part 46 are arranged in parallel and perpendicular to the several connecting parts 47. The connecting parts 47 are fixed in the middle of the several connecting parts 47. The outer walls of one end of the several connecting parts 47 close to the water inlet part 45 are expanded outward to form several abutting parts 471 whose outer diameter is larger than the outer diameter of the water outlet part 46. The outer walls of the other ends of the several connecting parts 47 are arranged to be inclined and retracted inward in a direction away from the abutting parts 471 to a mounting part 472 whose outer diameter is adapted to the outer diameter of the water outlet part 46. The outer diameter of the water inlet part 45 is larger than the outer diameter of the water inlet end of the water outlet channel 3. Specifically, the several abutting parts 471 are arranged with interference fit with the water outlet channel 3. Thus, the rectifying component 4 can be conveniently inserted into the water inlet end of the water outlet channel 3 through the inclined guidance of the several mounting portions 472, and the rectifying component 4 can be stably inserted in the water outlet channel 3 through the interference fit between the several abutting portions 471 and the water outlet channel 3. At the same time, by setting the outer diameter of the water inlet portion 45 to be larger than the water inlet end of the water outlet channel 3, the rectifying component 4 can be conveniently pulled out to separate it from the water outlet channel 3.

[0039] Based on the above structure, after the water outlet portion 46 and the water retaining portion 43 are plugged in the water inlet end of the water outlet channel 3 through the plurality of the mounting portions 472 and the abutting portion 471, a gap is set between the plurality of the mounting portions 472 and the water outlet portion 46 and the water inlet end of the water outlet channel 3. Therefore, in order to facilitate the installation of the rectifying member 4 and avoid excessive influence of the gap between the plurality of the mounting portions 472 and the water outlet portion 46 and the water inlet end of the water outlet channel 3 on the slow flow effect of the rectifying member 4, the inner diameter of the water outlet hole 461 gradually increases in the direction away from the water retaining portion 43. Thereby, the water outlet area of ​​the water outlet hole 461 is increased, so that most of the water that first turns outward to the water inlet area 41 and flows through the slow flow area 44 turns inward to the water outlet area 42 and then turns forward to the water outlet hole 461 to discharge water. Only a very small amount of water in the slow flow area 44 directly enters the water outlet channel 3 along the above-mentioned gap. The influence of the above-mentioned very small amount of water on most of the water after the slow flow effect of the rectifying component 4 is low to be negligible. Therefore, on the premise of facilitating the installation of the rectifying component 4, the stability of the slow flow effect of the rectifying component 4 is ensured, and then the splash stability of the blade water is ensured.

[0040] In order to improve the structural stability of the fairing 4 and reduce the production cost, the outer wall of the water retaining part 43 extends outward to the middle of the adjacent connecting parts 47, and the water inlet 45, the water outlet 46, the water retaining part 43, and the connecting parts 47 are integrally formed. Specifically, the fairing 4 can be formed as a whole by injection molding. Thereby, the connection strength between the water retaining part 43 and the connecting parts 47 is improved, and the various parts of the fairing 4 are integrated to improve the overall structural strength, and can be integrally formed by injection molding to reduce the manufacturing cost.

[0041] In order to further improve the slow flow effect of the blade water outlet structure as a whole, the outlet channel 3 is arranged in a columnar shape, the blade water jet hole 5 is arranged in a flat fan shape with an inner diameter gradually increasing in the direction away from the outlet channel 3, the inner diameter of the water inlet end of the blade water jet hole 5 is smaller than the inner diameter of the water outlet end of the outlet channel 3, and the outlet end of the outlet channel 3 is arc-shaped and shrinks inward to form a buffer portion 31 connected to the water inlet end of the blade water jet hole 5. Therefore, before the water flow passes through the outlet channel 3 to the blade water jet hole 5 after the slow flow effect of the rectifying member 4, it first flows slowly through the buffer portion 31 and then outputs high-pressure blade water from the blade water jet hole 5, further improving the slow flow effect of the blade water outlet structure as a whole, ensuring the stability of the blade water splash, and avoiding the generation of spray.

[0042] In order to avoid the blade water outputted from several blade water outlet structures from overlapping and colliding to produce water mist, several blade water outlet structures are arranged at intervals in a ring, several blade water injection holes 5 are arranged in parallel and on different planes, and the outlet ends of several blade water injection holes 5 are arranged in a plane with the outer wall of the outlet end of the water outlet body 1. In this embodiment, the number of blade water outlet structures is set to two. In other embodiments, the number can be adjusted adaptively according to specific circumstances. As a result, the blade water outputted from the blade water injection holes 5 of several blade water outlet structures are parallel and on different planes, avoiding the overlap and collision of several blade water to produce water mist, ensuring the stability of the blade water splash, and further improving the outlet stability of several blade water. In addition, the outlet ends of several blade water injection holes 5 are arranged in a plane with the outer wall of the outlet end of the water outlet body 1, which can improve the flatness of the outlet end surface of the water outlet device for easy cleaning.

[0043] Specifically, the water outlet device can be set as a water outlet nozzle, etc. The water outlet body 1 includes a main shell 11 and a water outlet shell 12 detachably arranged in the water outlet end of the main shell 11, a plurality of blade water outlet structures are arranged in the water outlet shell 12, and a plurality of conventional water outlet structures 8 are also penetrated in the water outlet shell 12, the water inlet channel 2 is arranged in the main shell 11 and the water outlet end includes a first water channel 21 and a plurality of second water channels 22 respectively connected to the conventional water outlet structure 8 and a plurality of the water inlet areas 41, and the main shell 11 includes a switch valve 6 for controlling the opening and closing of the water outlet channel 3, and a switching valve 7 for controlling the opening and closing of the first water channel 21 and a plurality of the second water channels 22. The switch valve 6, the switching valve 7 and the conventional water outlet structure 8 are prior art, and their specific structures are not the main invention points of this application, and are not described in detail here.

[0044] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
