Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0030] like Figure 1~Figure 4 As shown, this embodiment proposes a water outlet device with a flow limiting function, including a support 1, the outer surface of the support 1 is respectively fixedly connected to a water inlet pipe 2 and a water outlet pipe 3, the surface of the support 1 is rotatably connected to a power shaft 4, the other end of the power shaft 4 is connected to a main motor 5 that provides power to the power shaft 4, the middle of the water outlet pipe 3 is connected to a flow limiting structure 6, and the surface of the power shaft 4 is connected to a fine-tuning structure 7;

[0031] The flow limiting structure 6 includes a regulating box 61 fixedly connected to the outer surface of the water outlet pipe 3, a detachable protective shell 62 is connected between the upper end of the regulating box 61 and the water outlet pipe 3, a movable rod 63 is connected through the surface of the regulating box 61, a cross bar 64 is fixedly connected to the top of the movable rod 63, a screw rod 65 is connected through the outer surface of the cross bar 64, one end of the screw rod 65 is connected to a lifting motor 60 for providing rotational power to the screw rod 65, the lower end of the movable rod 63 is fixedly connected to a push rod 66, and a flow limiting component for cooperating with the push rod 66 to adjust the flow is arranged inside the regulating box 61.

[0032] The current limiting assembly includes a shaft 68 rotatably arranged inside the regulating box 61, the outer surface of the shaft 68 is fixedly connected to an inclined plate 67, the inner surface of the inclined plate 67 is hinged with a buffer plate 69, and a buffer spring 610 and a damping member 611 are respectively connected between the buffer plate 69 and the inclined plate 67.

[0033] The interior of the adjustment box 61 is a cavity structure, and the protective shell 62 is used to protect the cross rod 64, the movable rod 63, the screw rod 65 and the lifting motor 60. The movable rod 63 slides up and down along the adjustment box 61, and the screw rod 65 and the cross rod 64 are threadedly connected; a group of cross rods 64 corresponds to two groups of movable rods 63 and are symmetrically distributed, the output end of the lifting motor 60 is fixedly connected to the screw rod 65, and the number of cross rods 64 is two groups and is symmetrically distributed.

[0034] The two ends of the push rod 66 are fixedly connected to the two groups of movable rods 63 on the same side, the inclined plate 67 is rotatably connected to the adjustment box 61 through the shaft 68, the buffer spring 610 is an arc-shaped structure arranged between the buffer plate 69 and the inclined plate 67, and the two end ends of the buffer spring 610 are respectively fixedly connected to the inclined plate 67 and the buffer plate 69; the damping member 611 is composed of two groups of arc-shaped and mutually socketed pipes, the two groups of pipes are respectively fixedly connected to the buffer plate 69 and the inclined plate 67, and the damping member 611 and the buffer spring 610 are used to cooperate with the buffer plate 69 to form a buffer.

[0035] In this embodiment, the size of the cross-sectional opening of the regulating box 61 can be freely adjusted to allow water to flow through, and the flow diameter of the water flow can be automatically controlled according to the needs of the user, thereby achieving the effect of flow limiting. At the same time, it can effectively reduce the impact force when the water outlet device is just started, making the structure outside the device that maintains the flow of water more durable.

[0036] When the flow rate of water outlet needs to be adjusted, the user can control the lifting motor 60 to drive the screw rod 65 to rotate forwardly. At this time, the cross bar 64 will move downward along the screw rod 65, and the movable rod 63 will move downward synchronously through the downward movement of the cross bar 64. At the same time, the inclined plate 67 is pushed downward by the movable rod 63 to rotate downward. The opening formed by the two sets of inclined plates 67 cooperating with the regulating box 61 limits the caliber of the water flow out of the opening. The size of the opening of the two sets of inclined plates 67 can be adjusted by the forward and reverse rotation of the screw rod 65.

[0037] Through the action of the buffer plate 69, the buffer spring 610 and the damping member 611, a buffering effect can be formed when the water flows upward from the bottom. Through the reverse pushing of the buffer spring 610 and the damping member 611, and the blocking of the buffer plate 69, the impact force of the water when it just starts to flow is effectively reduced. At the same time, a certain interval is formed between the buffer plate 69 and the inclined plate 67 separated by the buffer spring 610 and the damping member 611. When the water flows from the bottom to the top, the two groups of inclined plates 67 can be automatically flipped upward by the impact of the water flow to reduce the diameter, and then the push rod 66 pushes the inclined plate 67 downward, so that the two groups of inclined plates 67 can be freely adjusted to cooperate with the adjustment box 61 to adjust the diameter of the water flow. While achieving the flow limiting function, the impact force of the water flow on the pipeline when the equipment is just started can be reduced. Example

[0038] like Figure 5~Figure 6 As shown, on the basis of Example 1, a fine-tuning structure 7 is further proposed, which includes a stabilizing bracket 71 arranged on the outside of the power shaft 4, the outer surface of the stabilizing bracket 71 is fixedly connected to the longitudinal frame 72, the inner side of the longitudinal frame 72 is slidably connected to the sliding plate 73, the outer surface of the sliding plate 73 is penetrated by a rotating rod 74, the outer surface of the rotating rod 74 is provided with two groups of symmetrical threaded portions 75, the outer surface of the stabilizing bracket 71 is fixedly connected to a servo motor 76 at one end of the rotating rod 74 corresponding to the outer surface of the stabilizing bracket 71, one end of the sliding plate 73 is hinged to a connecting rod 77, one end of the connecting rod 77 is hinged to a connecting block 78, and the lower end of the connecting block 78 is connected to a universal ball 79.

[0039] There are three groups of longitudinal frames 72 and they are symmetrically distributed. The surface of the sliding plate 73 has a protrusion that can slide in the slide groove 70 along its length direction. The rotating rod 74 is threadedly connected to the sliding plate 73, and the rotating rod 74 is rotatably connected to the stabilizing bracket 71 through a bearing; the number of rotating rods 74 is equal to the longitudinal frames 72, and the positions of the two correspond one to one. One group of rotating rods 74 corresponds to two groups of sliding plates 73 and they are symmetrically distributed. One group of rotating rods 74 corresponds to two groups of connecting rods 77 corresponding to one group of connecting blocks 78; one group of connecting blocks 78 corresponds to two groups of universal balls 79 and they are symmetrically distributed. The bracket part of the universal ball 79 is fixedly connected to the connecting block 78, the spherical part of the universal ball 79 is point-connected to the power shaft 4, and when the power shaft 4 rotates, the universal ball 79 and the power shaft 4 are rollingly connected.

[0040] In this embodiment, the position of the power shaft 4 can be fine-tuned. By applying forces of different magnitudes to the power shaft 4 in multiple directions, the rotational position of the power shaft 4 can be limited and fixed, thereby achieving a fine-tuning effect, making the power shaft 4 run smoothly and reducing the offset of the power shaft 4 during rotation.

[0041] During use, when the rotation of the power shaft 4 produces a certain offset, the servo motor 76 can be used to drive the rotating rod 74 to rotate in the forward direction, and the two sets of sliding plates 73 can be brought close to each other through the cooperation of the threaded portion 75, the rotating rod 74 and the sliding plate 73. At this time, the two sets of connecting rods 77 can push the connecting block 78 toward the direction of the power shaft 4, and the universal ball 79 on the connecting block 78 will press the surface of the power shaft 4. The two sets of universal balls 79 push the power shaft 4 to reduce the offset of the rotation of the power shaft 4. At the same time, multiple sets of connecting blocks 78 push the power shaft 4 and can push out forces of different sizes, thereby effectively maintaining the stability of the power shaft 4 during rotation.

[0042] In summary, the working principle of the present invention is as follows:

[0043] When in use, the main motor 5 can be used to start the operation, and the main motor 5 drives the power shaft 4 to rotate, and the rotation of the power shaft 4 drives the impeller to rotate, so that the water at one end of the pipe connected to one end of the water inlet pipe 2 is transported to one end of the water outlet pipe 3, thereby achieving the effect of water outlet;

[0044] During use, when the flow rate of water needs to be adjusted, the user can control the lifting motor 60 to drive the screw rod 65 to rotate forwardly. At this time, the cross bar 64 will move downward along the screw rod 65, and the downward movement of the cross bar 64 will drive the movable rod 63 to move downward synchronously. At the same time, the movable rod 63 pushes the inclined plate 67 downward to rotate downward. The opening formed by the two sets of inclined plates 67 cooperating with the regulating box 61 limits the caliber of the water flow out of the opening. The size of the opening of the two sets of inclined plates 67 can be adjusted by the forward and reverse rotation of the screw rod 65.

[0045] Through the action of the buffer plate 69, the buffer spring 610 and the damping member 611, a buffering effect can be formed when the water flows upward from the bottom. Through the reverse pushing of the buffer spring 610 and the damping member 611, and the blocking of the buffer plate 69, the impact force of the water when it just starts to flow is effectively reduced. At the same time, a certain interval is formed between the buffer plate 69 and the inclined plate 67 separated by the buffer spring 610 and the damping member 611. When the water flows from the bottom to the top, the two groups of inclined plates 67 can be automatically flipped upward by the impact of the water flow to reduce the diameter, and then the push rod 66 pushes the inclined plate 67 downward, so that the two groups of inclined plates 67 can be freely adjusted to cooperate with the adjustment box 61 to adjust the diameter of the water flow. While achieving the flow limiting function, the impact force of the water flow on the pipeline when the equipment is just started can be reduced.

[0046] During use, when the rotation of the power shaft 4 produces a certain offset, the servo motor 76 can be used to drive the rotating rod 74 to rotate in the forward direction, and the two sets of sliding plates 73 can be brought close to each other through the cooperation of the threaded portion 75, the rotating rod 74 and the sliding plate 73. At this time, the two sets of connecting rods 77 can push the connecting block 78 toward the direction of the power shaft 4, and the universal ball 79 on the connecting block 78 will press the surface of the power shaft 4. The two sets of universal balls 79 push the power shaft 4 to reduce the offset of the rotation of the power shaft 4. At the same time, multiple sets of connecting blocks 78 push the power shaft 4 and can push out forces of different sizes, thereby effectively maintaining the stability of the power shaft 4 during rotation.

[0047] It should be noted that one end of the power shaft 4 extends through the interior of the support 1, and the power shaft 4 is fixedly connected to a partial surface corresponding to the interior of the support 1 with an impeller, which is used to transport water from one end of the outlet pipe 3 to the other end of the outlet pipe 3 to achieve the purpose of water discharge, wherein components such as the impeller are not shown in the present invention.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
