Detailed Description

The invention will be further illustrated by way of example with reference to the accompanying drawings, without thereby limiting the scope of the invention to the examples.

As shown in fig. 1-3, the present embodiment provides a water pump 100.

The water pump 100 of the present invention refers to a device that has a pumping action on a fluid, and the pumped fluid is not limited to water.

The water pump 100 includes: a housing 110, an impeller 114 disposed within the housing 110, and a splitter support 120.

The housing 110 includes a water inlet pipe 111, a water outlet pipe 112, and a main body portion 113, and both the water inlet pipe 111 and the water outlet pipe 112 are communicated with the main body portion 113. Fluid enters the main body portion 113 through the water inlet pipe 111, is pressurized by the impeller 114, and is discharged through the water outlet pipe 112.

The main body portion 113 accommodates the impeller 114, and the axial center of the impeller 114 faces the fluid outlet of the water inlet pipe 111. When water enters from the inlet tube 111, such as without the diverter bracket 120, it will directly impinge on the shaft 1141 and sleeve 1142 of the impeller 114.

The splitter support 120 is at least partially disposed within the inlet tube 111 and upstream of the impeller 114. As shown in fig. 2, the upper half of the diverting bracket 120 is accommodated in the water inlet pipe 111, and the lower half is accommodated in the main body portion 113, thereby being engaged with the impeller 114 and located on the upstream side of the impeller 114. The volume of the splitter support 120 received within the inlet tube 111 is determined by the location at which the impeller 114 is positioned and the manner of engagement with the impeller 114.

The diverting bracket 120 provided at the upstream side of the impeller 114 can prevent the shaft 1141 and the sleeve 1142 of the impeller 114 from being directly impacted.

The impeller 114 rotates in a first direction. The first direction may be a counterclockwise direction or a clockwise direction.

As shown in fig. 4-7, the shunt support 120 includes a body 121; the body 121 has an interior cavity 1211 disposed within the body 121, a water inlet 1212 disposed at a first end 1214 of the body 121, and a water outlet disposed at a side of the body 121; both the water inlet 1212 and the water outlet are in communication with the interior cavity 1211; the second end 1215 of the body 121 is closed; the water outlet comprises a plurality of flow channels 1216, the flow channels 1216 extending helically in a direction from the first end 1214 towards the second end 1215 of the body 121.

"spiral extension" herein means that the flow channel extends in a spiral shape.

In the present embodiment, the body 121 is provided with a plurality of flow passages 1216, but the present invention is not limited thereto, and one skilled in the art may provide only one flow passage 1216 as needed.

When water enters the inner cavity 1211 of the body 121 of the split bracket 120, the water flows out of the spiral flow channel 1216 on the side surface, so that the direct impact on the shaft 1141 and the shaft sleeve 1142 of the impeller 114 is avoided, the water flow forms a shaft 1141-direction rotation, the water is accelerated at a rotation speed before entering the impeller 114, the resistance of the water entering the impeller 114 is reduced, and more kinetic energy is obtained after the water enters the impeller 114.

In the present embodiment, the flow passage 1216 is formed in an elongated shape and has a uniform width, but the present invention is not limited thereto, and may be formed in other irregular shapes, and the width of the flow passage 1216 in the extending direction may be changed according to actual needs, for example, gradually narrowed or gradually widened from the first end 1214 to the second end 1215.

The spiral shape is formed by movement in a clockwise or counterclockwise direction during processing from first end 1214 to second end 1215.

The flow channels 1216 of the shunt support 120 extend helically in a first direction.

The rotational direction of the water flowing out of the diverting bracket 120 coincides with the rotational direction of the impeller 114, thereby reducing the resistance of the water entering the impeller 114.

In this embodiment, the flow passage 1216 extends from the first end 1214 of the body 121 to the second end 1215 of the body 121.

The flow passage 1216 extends from the first end 1214 of the body 121 to the second end 1215 of the body 121 such that the path of extension of the flow passage 1216 is maximized, thereby outputting more fluid. And because the flow passage 1216 extends from the first end 1214 of the body 121 to the second end 1215 of the body 121, the first end 1214 of the body 121 forms an elastically deformable structure, as described in greater detail below.

Alternatively, the flow channels 1216 may extend from the middle of the body 121 or only in the middle of the body 121, not to the ends of the body 121.

The first end 1214 of the body 121 is provided with an engagement portion 1217.

In the present embodiment, the engaging portion 1217 is a protrusion protruding toward the outer peripheral side of the body 121, which is matched with a groove provided on the inner peripheral wall of the water inlet pipe 111, and the diverting bracket 120 is fixed in the water inlet pipe 111 when the protrusion is engaged in the groove. In other embodiments, the engaging portion 1217 may be a groove provided at the first end 1214 of the body 121, the groove matching with a protrusion provided on the inner peripheral wall of the water inlet pipe 111, and the diverting bracket 120 is fixed in the water inlet pipe 111 when the protrusion is engaged in the groove.

The split bracket 120 is mounted and fixed to the water pump 100 by the engagement portion 1217 provided at the first end 1214 of the body 121.

The body 121 includes a plurality of partitions 1218 arranged circumferentially, and a flow passage 1216 is formed between two adjacent partitions 1218. In this embodiment, the flow passage 1216 is formed by providing a plurality of partitions 1218 at intervals.

In other embodiments, the flow channels 1216 may be formed in other possible ways, such as where the flow channels 1216 extend only in the middle section of the body 121.

The body 121 is provided with a plurality of engaging portions 1217, and the engaging portions 1217 are provided at an end of the partition portion 1218 near the first end 1214.

Since the flow passage 1216 extending from the first end 1214 is provided between the partition portions 1218, the end portion of the adjacent partition portion 1218 near the first end 1214 has a certain elasticity and can be gathered or separated from each other, so that the engaging portion 1217 can be engaged with the water inlet pipe 111 of the water pump 100.

Referring to fig. 2, the diverting bracket 120 is put into the water inlet pipe 111 from below the housing 110, when the diverting bracket 120 is inserted into the water inlet pipe 111 of the housing 110, the plurality of partition portions 1218 are gathered together, that is, the end portion of the partition portion 1218 near the first end 1214 is moved toward the inner circumferential side, so that the diameter of the first end 1214 of the body 121 of the diverting bracket 120 is reduced, so that the maximum outer diameter thereof including the engaging portion 1217 is less than or equal to the inner diameter of the water inlet pipe 111, so that the diverting bracket 120 can be inserted into the water inlet pipe 111, and after the diverting bracket 120 is inserted, when the engaging portion 1217 is moved to the groove provided on the inner wall of the water inlet pipe 111, the engaging portion 1217 is engaged into the groove, and the partition portion 1218 is deformed by elastic force, whereby the diverting bracket 120 is fixed in the water inlet pipe 111. The impeller 114 is then mounted under the splitter support 120.

The plurality of engaging portions 1217 are preferably arranged at equal intervals to achieve uniform force.

The diverting bracket 120 further comprises a base 122, wherein the base 122 is arranged at the second end 1215 of the body 121 and seals the second end 1215 of the body 121, the base 122 is provided with a water outlet, and the water outlet is communicated with the inner cavity 1211 of the body 121 and the outer side of the body 121.

The second end 1215 of the body 121 is closed by the base 122 while water in the interior 1211 of the body 121 is drained through a drain opening in the base 122 to avoid water retention in the interior 1211 of the body 121.

Alternatively, the base 122 may not be provided, and the second end 1215 of the body 121 may be closed in other manners.

Preferably, the drain opening is provided on a surface of the base 122 facing the body 121.

By providing the drain opening on the surface of the base 122 facing the body 121, direct impingement of water flow on the other side of the base 122 is avoided, thereby impacting the shaft 1141 and sleeve 1142 of the impeller 114 of the water pump 100.

The drain port includes a plurality of drain holes 1221 uniformly provided along the circumferential direction of the body 121. Of course, the present invention is not limited thereto, and those skilled in the art can provide other forms of drain ports as desired. The drain hole 1221 is inclined in a direction from the first end 1214 toward the second end 1215 and in a peripheral direction to facilitate draining the flow path from the interior cavity 1211 of the body 121 along the direction of fluid flow.

The base 122 protrudes annularly toward the outer peripheral side with respect to the body 121. The base 122 protrudes towards the outer circumference in a ring shape, and the water flows out to the periphery and the bottom after being stored and stabilized in a short time by the inner cavity 1211, so that the water flow can be more uniform when flowing to all directions of the impeller 114, the impeller 114 can run more stably without great up-and-down shaking, and energy loss is caused, thereby improving the flow and the lift of the water pump 100.

The bottom surface of the base 122 is provided with a relief groove 1222, and the relief groove 1222 is used for relieving the shaft 1141 of the impeller 114, and the shaft 1141 of the impeller 114 is partially inserted into the relief groove 1222, so that the size of the water pump 100 is prevented from being increased due to the installation of the split bracket 120.

The shunt support 120 is formed in a generally cylindrical configuration with an inner lumen 1211 that is also cylindrical. The cylindrical structure fits the circular cross-section of the inlet pipe 111 of the water pump 100. Of course, alternatively, the shunt support 120 may be formed in other shapes, and those skilled in the art will appreciate that any shape may have a central axis extending from the first end 1214 toward the second end 1215, and having a circumferential direction centered on the central axis, as well as a diametrical direction.

After the fluid of the water pump 100 enters from the water inlet pipe 111, the fluid flows into the inner cavity 1211 of the body 121 of the split support 120 through the water inlet 1212 of the split support 120, then flows out from the flow passage 1216 on the side surface of the split support 120, so that the direct impact on the shaft 1141 and the shaft sleeve 1142 of the impeller 114 is avoided, the water flow forms a rotation in the axial direction 1141, the water is accelerated in advance at a rotation speed before entering the impeller 114, the resistance of the water entering the impeller 114 is reduced, and more kinetic energy is ensured after the water enters the impeller 114.

In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present invention.
