DETAILED DESCRIPTION

[0022] In order to enable the above-mentioned purposes, features and advantages of the present application to be more clearly understood, the present application will be further described below with reference to the drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be practiced in other ways different from those described herein, therefore, the present application is not limited to the specific embodiments disclosed in the following description.

[0024] Embodiment one: as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the present application provides an energy-saving type tap water supply booster pump, comprising an asynchronous motor 1 and a pump shell 3, an asynchronous motor 1 and a pump shell 3 are fixedly connected with a coupling 2, one side of the pump shell 3 is fixedly connected with an energy-saving assembly 4;

[0025] The energy-saving assembly 4 comprises a pipe 41, a filling ring 44, a guide plate 45 and a partition plate 46, one end of the pipe 41 is fixedly connected with the pump shell 3, the filling ring 44 is slidably connected on the inner wall of the pipe 41, one end of the guide plate 45 is fixedly connected with one side of the filling ring 44, the other end of the guide plate 45 is fixedly connected with the edge of the partition plate 46, the partition plate 46 is located on one side of the pump shell 3, and the adjacent two guide plates 45 are provided with an opening 49;

[0026] One end of the coupling 2 is fixedly connected with an impeller 6, the impeller 6 is located in the interior of the pump shell 3, an arc-shaped flow channel 5 is formed on the inner wall of the pump shell 3, and an arc-shaped slope 7 is arranged on the side surface of the impeller 6.

[0027] Now the specific settings and effects of the present embodiment will be described, the output shaft of the asynchronous motor 1 is fixedly connected with the impeller 6 in the interior of the pump shell 3 through the coupling 2, in use, when the impeller 6 rotates at high speed in the pump shell 3, the water will generate centrifugal force, under the action of the centrifugal force, the water is thrown from the center of the impeller 6 to the edge, and then is sent to the outlet along the arc-shaped flow channel 5 of the pump shell 3, so as to increase the pressure of the water, and the arc-shaped slope 7 arranged on the side surface of the impeller 6 can ensure that the impeller 6 does not contact with the energy-saving assembly 4.

[0028] The energy-saving assembly 4 is installed at the water inlet of the pump shell 3. In use, the centrifugal force will draw water from the pipeline 41 into the pump shell 3. In this process, the impact of the water flow will push the partition plate 46 into the interior of the pump shell 3 together. Finally, the partition plate 46 and the guide plate 45 will be at the junction of the pump shell 3 and the pipeline 41. The filling ring 44 can ensure that the guide plate 45 and the partition plate 46 will not shake, but the partition plate 46 will not contact the impeller 6. Under the guidance of the guide plate 45, the water will flow into the pump shell 3 from the opening 49. In this process, high-intensity impact on the impeller 6 will not be generated, the energy loss of the impeller 6 is reduced, thereby playing a role in energy saving.

[0029] The asynchronous motor 1 is prior art, and will not be described in detail here.

[0030] Embodiment two: as shown in Figure 2 and Figure 3 The inner wall of the pipeline 41 is fixedly installed with a limiting ring 42. The intersection between the limiting ring 42 and the pipeline 41 is fixedly installed with an annular convex strip 48. One side of the filling ring 44 is fixedly connected with a guide rod 43. The other end of the guide rod 43 is slidingly connected in the interior of the limiting ring 42. The intersection between the limiting ring 42 and the guide rod 43 is provided with a through hole 47. The limiting ring 42 and the filling ring 44 are fixedly connected with a tensile spring 410, which is sleeved on the outer wall of the guide rod 43.

[0031] The effect of the whole embodiment is that the limiting ring 42 is fixed in the interior of the pipeline 41 through the annular convex strip 48. The annular convex strip 48 is embedded on the inner wall of the pipeline 41, which ensures the stability of the overall structure. When the water flow pushes the partition plate 46, the partition plate 46 will drive the filling ring 44 through the guide plate 45. The filling ring 44 pulls the guide rod 43 to move along the direction of the through hole 47, so that the partition plate 46 and the guide plate 45 can smoothly enter the pump shell 3. When there is no water flow subsequently, the rebound of the tensile spring 410 will pull the filling ring 44 back to the initial position, so that the partition plate 46 moves back to the interior of the pipeline 41, which is used for simple partitioning, reduces the total amount of air entering the pump shell 3, and prolongs the service life of the impeller 6.

[0032] The working principle and method of using the device are as follows: in use, when the impeller 6 rotates at high speed in the pump shell 3, water will generate centrifugal force under the action of the centrifugal force. The water is thrown from the center of the impeller 6 to the edge, and then is sent to the outlet along the arc-shaped flow channel 5 of the pump shell 3, thereby increasing the pressure of the water.

[0033] The centrifugal force can draw the water from the pipeline 41 into the pump shell 3, in the process, the impact of the water flow can push the partition plate 46, the partition plate 46 drives the filling ring 44 through the guide plate 45, the filling ring 44 pulls the guide rod 43 to move along the direction of the through hole 47, so that the partition plate 46 and the guide plate 45 can smoothly enter the pump shell 3, finally the partition plate 46 and the guide plate 45 can be at the junction of the pump shell 3 and the pipeline 41, under the guidance of the guide plate 45, the water can flow into the pump shell 3 from the opening 49, in the process, the high-intensity impact on the impeller 6 can not be generated;

[0034] When no water flow passes subsequently, the extension spring 410 can pull the filling ring 44 back to the initial position, so that the partition plate 46 moves back to the inside of the pipeline 41, the total amount of air entering the pump shell 3 is reduced, and the service life of the impeller 6 is prolonged.

[0035] The above is only the preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields. However, any simple modification, equivalent change and modification of the above embodiments made according to the technical essence of the present application without departing from the technical scheme of the present application still belongs to the protection scope of the present application.
