[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 like Figure 1-4 As shown, this utility model provides a technical solution: a flow control device for a large flow pump, comprising: a pump body 1, an outlet pipe 2 fixedly connected to the outer surface of the pump body 1, a flow control mechanism 3 provided on one side of the pump body 1, the flow control mechanism 3 including a spring 31, a support column 32 sleeved on the inner wall of the spring 31, an L-shaped plate 33 slidably connected to the outer surface of the support column 32, an L-shaped plate 34 slidably connected to the outer surface of the support column 32, a pressure plate 35 fixedly connected to the outer surface of the L-shaped plate 34, and a pressure plate 36 fixedly connected to the outer surface of the L-shaped plate 33. The outer surface of the control plate 33 is fixedly connected to the control plate 37, and the outer surface of the control plate 37 is fixedly connected to the waterproof pad 38. The inner wall of the L-shaped plate 34 is slidably connected to the outer surface of the support rod 310. Multiple control slots 313 are symmetrically opened. The inner wall of the flow control mechanism 3 is slidably connected to the outer surface of the control plate 37. The outer surface of the pressure plate 35 is slidably connected to the inner wall of the flow control mechanism 3. The outer surface of the pressure plate 36 is slidably connected to the inner wall of the flow control mechanism 3. One end of the spring 31 is fixedly connected to the outer surface of the L-shaped plate 33, and the other end of the spring 31 is fixedly connected to the outer surface of the L-shaped plate 34.

[0020] In this embodiment, the design of the outlet pipe 2 ensures the water output of the pump body 1, and the design of the flow control mechanism 3 controls the water flow rate. The support column 32 is sleeved on the inner wall of spring 31, and one end of spring 31 is fixedly connected to the outer surface of L-shaped plate 33, while the other end of spring 31 is fixedly connected to the outer surface of L-shaped plate 34. L-shaped plates 33 and 34 are slidably connected to the outer surface of the support column 32, respectively. Meanwhile, the outer surface of L-shaped plate 33... A pressure plate 36 is fixedly connected to the surface of the L-shaped plate 34, and a pressure plate 35 is fixedly connected to the outer surface of the L-shaped plate 34. Pressing the pressure plate 35 and the pressure plate 36 simultaneously can drive the L-shaped plate 33 and the L-shaped plate 34 to move. A control plate 37 is fixedly connected to the outer surface of the L-shaped plate 33 and the L-shaped plate 34 respectively, and a waterproof pad 38 is fixedly connected to the outer surface of the control plate 37. This allows the control plate 37 and the waterproof pad 38 to move simultaneously with the movement of the L-shaped plate 33 and the L-shaped plate 34.

[0021] Example 2 like Figure 1-4 As shown, a support rod 310 is slidably connected to the inner wall of the L-shaped plate 33. A spring 39 is sleeved on the outer surface of the support rod 310. A fixing block 311 is fixedly connected to one end of the support rod 310, and a fixing block 312 is fixedly connected to the other end of the support rod 310. A control groove 313 is provided on the inner wall of the water pump body 1. One end of the spring 39 is fixedly connected to the inner wall of the L-shaped plate 33, and the other end of the spring 39 is fixedly connected to the outer surface of the L-shaped plate 34.

[0022] In this embodiment, a support rod 310 is sleeved on the inner wall of spring 39, and one end of spring 39 is fixedly connected to the outer surface of L-shaped plate 33, while the other end of spring 39 is fixedly connected to the outer surface of L-shaped plate 34. The outer surface of the support rod 310 is slidably connected to the inner walls of L-shaped plate 33 and L-shaped plate 34, respectively. At the same time, fixing blocks 311 and 312 are fixedly connected to both ends of the support rod 310, respectively, to achieve the stability of L-shaped plate 33 and L-shaped plate 34 during movement and to prevent them from falling off. The flow rate is controlled by the design of multiple control slots 313.

[0023] Working principle: like Figure 1-4 As shown, When pressure plates 35 and 36 are pressed simultaneously, springs 31 and 39 are compressed. Since pressure plate 35 is fixed to L-shaped plate 34 and pressure plate 36 is fixed to L-shaped plate 33, the pressure directly causes L-shaped plates 33 and 34 to move relative to each other. L-shaped plates 33 and 34 are respectively fitted onto support column 32 and support rod 310, and can slide stably along these two rods. As L-shaped plates 33 and 34 move, control plate 37 and waterproof pad 38, which are fixedly connected to them, move synchronously. The cooperation between control plate 37 and control groove 313 enables the waterproof pad 38 on control plate 37 to correspond with multiple preset control grooves 313. When control plate 37 moves to different control groove 313 positions, control plate 37 and waterproof pad 38 block the control groove 313, thereby controlling the water pump output flow.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
