Description

Technical Field

[0001] This invention relates to the field of water pumps, and particularly to a flow divider bracket for a water pump and a water pump. Background Technology

[0002] Nowadays, people pursue a high quality of life, and booster pumps are frequently used when using water heaters to ensure sufficient water flow for bathing. When water enters the pump from the inlet pipe, it directly impacts the pump impeller's central shaft and bushing. Furthermore, turbulence at the inlet bend causes an imbalance in the impact force on the shaft and bushing as the water flows down the straight section, resulting in significant horizontal wobbling of the impeller. Horizontal wobbling of the impeller during pump operation negatively impacts the pump's flow rate, head, and overall performance, leading to performance degradation. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defect of water flow directly impacting the impeller of the water pump in the prior art, and to provide a flow divider bracket and water pump for the water pump.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A diversion bracket for a water pump, the diversion bracket comprising a body;

[0006] The body has an inner cavity located inside the body, a water inlet located at the first end of the body, and a water outlet located on the side of the body.

[0007] Both the inlet and outlet are connected to the inner cavity;

[0008] The second end of the body is closed;

[0009] The outlet includes one or more flow channels that extend spirally from the first end of the body toward the second end.

[0010] In this design, when water enters the inner cavity of the main body of the diversion bracket, it flows out from the spiral flow channel on the side, avoiding direct impact on the impeller shaft and bushing. The water flow forms an axial rotation, giving the water a rotational speed in advance before it enters the impeller, reducing the resistance of the water entering the impeller and ensuring that the water gains more kinetic energy after entering the impeller.

[0011] Preferably, the flow channel extends from a first end of the body to a second end of the body.

[0012] In this design, the flow channel extends from the first end of the body to the second end of the body, maximizing the extension path of the flow channel and thus outputting more fluid.

[0013] Preferably, the first end of the body is provided with an engaging portion.

[0014] In this solution, the diversion bracket is installed and fixed into the water pump through the engaging part provided at the first end of the main body.

[0015] Preferably, the body includes a plurality of partitions arranged circumferentially, with the flow channel formed between two adjacent partitions.

[0016] In this scheme, a flow channel is formed by setting multiple partitions at intervals.

[0017] Preferably, the body has a plurality of engaging portions, which are located at the end of the partition near the first end.

[0018] In this design, since there is a flow channel extending from the first end between the partitions, the ends of adjacent partitions near the first end have a certain degree of elasticity, allowing them to come together or separate, so that the engaging part can engage with the water pump's inlet pipe.

[0019] Preferably, the diversion bracket further includes a base, which is disposed at the second end of the body and closes the second end of the body. The base is provided with a drain outlet, which connects the inner cavity of the body and the outer side of the body.

[0020] In this design, the second end of the main body is sealed by the base, and the water in the inner cavity of the main body is drained through the drain port on the base to prevent water from stagnating in the inner cavity of the main body.

[0021] Preferably, the drain outlet is located on the surface of the base facing the body.

[0022] In this design, by placing the drain outlet on the surface of the base facing the main body, water flow can be prevented from directly impacting the other side of the base, thereby avoiding impact on the impeller shaft and bushing of the water pump.

[0023] Preferably, the base protrudes annularly relative to the body toward the outer periphery.

[0024] In this design, the base protrudes outward in a ring shape. This method, where water first passes through the inner cavity for a short period of storage and pressure stabilization before flowing out to the periphery and bottom, allows the water flow to be more uniform in all directions of the impeller. This makes the impeller run more smoothly and prevents large up-and-down swaying that would cause energy loss, thereby increasing the pump's flow rate and head.

[0025] A water pump includes: a housing, an impeller disposed inside the housing, and a flow divider as described above;

[0026] The housing includes an inlet pipe, and the diversion bracket is at least partially disposed inside the inlet pipe and located upstream of the impeller.

[0027] In this solution, the impeller shaft and bushing of the water pump including the aforementioned diversion bracket can be prevented from being directly impacted, and the water flow forms an axial rotation. Before the water enters the impeller, it is given a rotational speed to accelerate it in advance, reducing the resistance of the water entering the impeller and ensuring that the water obtains more kinetic energy after entering the impeller.

[0028] Preferably, the impeller rotates in a first direction, and the flow channel of the flow divider extends spirally toward the first direction.

[0029] In this design, the water flowing out of the diversion bracket rotates in the same direction as the impeller, thereby reducing the resistance to water entering the impeller.

[0030] The positive and progressive effects of this invention are as follows: when water enters the inner cavity of the body of the diversion support, it flows out from the spiral flow channel on the side, avoiding direct impact on the impeller shaft and bushing. Furthermore, the water flow forms an axial rotation, giving the water a rotational speed in advance before it enters the impeller, reducing the resistance of the water entering the impeller, and ensuring that the water obtains more kinetic energy after entering the impeller.

[0059] 1222 Detailed Implementation

[0060] The present invention will be further described below with reference to the accompanying drawings and by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0061] like Figure 1-3 As shown, this embodiment provides a water pump 100.

[0062] The water pump 100 of the present invention refers to a device that pumps fluids, and the pumped fluid is not limited to water.

[0063] The water pump 100 includes: a housing 110, an impeller 114 disposed inside the housing 110, and a flow divider bracket 120.

[0064] The housing 110 includes an inlet pipe 111, an outlet pipe 112, and a main body 113. Both the inlet pipe 111 and the outlet pipe 112 are connected to the main body 113. Fluid enters the main body 113 through the inlet pipe 111, is pressurized by the impeller 114, and is discharged through the outlet pipe 112.

[0065] The main body 113 houses the impeller 114, and the shaft of the impeller 114 is directly opposite the fluid outlet of the inlet pipe 111. When water flows in from the inlet pipe 111, without the diversion bracket 120, it will directly impact the shaft 1141 and bushing 1142 of the impeller 114.

[0066] The diversion bracket 120 is at least partially disposed within the inlet pipe 111 and located upstream of the impeller 114. For example... Figure 2 As shown, the upper half of the diversion bracket 120 is housed within the inlet pipe 111, while the lower half is housed within the main body 113, thereby engaging with the impeller 114 and being located upstream of the impeller 114. The volume of the diversion bracket 120 housed within the inlet pipe 111 is determined based on the position of the impeller 114 and the engagement method with the impeller 114.

[0067] The flow divider bracket 120 located upstream of the impeller 114 can prevent the shaft 1141 and bushing 1142 of the impeller 114 from being directly impacted.

[0068] The impeller 114 rotates in a first direction. This first direction can be either counterclockwise or clockwise.

[0069] like Figure 4-7 As shown, the diversion bracket 120 includes a body 121; the body 121 has an inner cavity 1211 disposed inside the body 121, an inlet 1212 disposed at the first end 1214 of the body 121, and an outlet disposed on the side of the body 121; the inlet 1212 and the outlet are both connected to the inner cavity 1211; the second end 1215 of the body 121 is closed; the outlet includes multiple flow channels 1216, which extend spirally from the first end 1214 of the body 121 toward the second end 1215.

[0070] The term "spiral extension" here refers to the flow channel extending into a spiral shape.

[0071] In this embodiment, the body 121 is provided with multiple flow channels 1216, but the present invention is not limited to this, and those skilled in the art can also provide only one flow channel 1216 as needed.

[0072] When water enters the inner cavity 1211 of the body 121 of the diversion bracket 120, it flows out from the spiral flow channel 1216 on the side, avoiding direct impact on the shaft 1141 and bushing 1142 of the impeller 114. The water flow forms a rotation in the direction of the shaft 1141, giving the water a rotational speed in advance before it enters the impeller 114, reducing the resistance of the water entering the impeller 114, and ensuring that the water obtains more kinetic energy after entering the impeller 114.

[0073] In this embodiment, the flow channel 1216 is formed into a long strip with a uniform width. However, the present invention is not limited to this. It can be formed into other irregular shapes. The width of the flow channel 1216 in the extension direction can also be changed according to actual needs. For example, it can gradually narrow or gradually widen from the first end 1214 to the second end 1215.

[0074] The spiral shape is formed by moving in a clockwise or counterclockwise direction during the processing from the first end 1214 to the second end 1215.

[0075] The flow channel 1216 of the diversion bracket 120 extends spirally in the first direction.

[0076] The water flowing out of the diversion bracket 120 rotates in the same direction as the impeller 114, thereby reducing the resistance of water entering the impeller 114.

[0077] In this embodiment, the flow channel 1216 extends from the first end 1214 of the body 121 to the second end 1215 of the body 121.

[0078] The flow channel 1216 extends from the first end 1214 of the body 121 to the second end 1215 of the body 121, maximizing the extension path of the flow channel 1216 and thus outputting more fluid. Furthermore, because the flow channel 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 detailed later.

[0079] Alternatively, the flow channel 1216 may extend from the middle of the body 121, or extend only in the middle section of the body 121 without extending to the end of the body 121.

[0080] The first end 1214 of the main body 121 is provided with a locking part 1217.

[0081] In this embodiment, the engaging portion 1217 is a protrusion protruding towards the outer periphery of the body 121. This protrusion matches a groove provided on the inner peripheral wall of the water inlet pipe 111. When the protrusion engages in the groove, the diverter bracket 120 is fixed in the water inlet pipe 111. In other embodiments, the engaging portion 1217 may also be a groove provided at the first end 1214 of the body 121. This groove matches a protrusion provided on the inner peripheral wall of the water inlet pipe 111. When the protrusion engages in the groove, the diverter bracket 120 is fixed in the water inlet pipe 111.

[0082] The diversion bracket 120 is installed and fixed into the water pump 100 through the engaging part 1217 provided at the first end 1214 of the main body 121.

[0083] The body 121 includes a plurality of circumferentially arranged partitions 1218, and a flow channel 1216 is formed between two adjacent partitions 1218. In this embodiment, the flow channel 1216 is formed by arranging a plurality of partitions 1218 at intervals.

[0084] In other embodiments, the flow channel 1216 may also be formed in other feasible ways, such as when the flow channel 1216 extends only in the middle section of the body 121.

[0085] The main body 121 is provided with a plurality of engaging portions 1217, which are located at the end of the partition portion 1218 near the first end 1214.

[0086] Since there is a flow channel 1216 extending from the first end 1214 between the partitions 1218, the ends of adjacent partitions 1218 near the first end 1214 have a certain elasticity and can come together or separate, so that the engaging part 1217 can engage with the water inlet pipe 111 of the water pump 100.

[0087] See Figure 2 The diversion bracket 120 is inserted into the inlet pipe 111 from below the housing 110. When the diversion bracket 120 is inserted into the inlet pipe 111 of the housing 110, the multiple partitions 1218 come together, causing the ends of the partitions 1218 near the first end 1214 to move towards the inner circumference. This reduces the diameter of the first end 1214 of the body 121 of the diversion bracket 120, so that its maximum outer diameter, including the engaging part 1217, is less than or equal to the inner diameter of the inlet pipe 111, allowing the diversion bracket 120 to be inserted into the inlet pipe 111. After the diversion bracket 120 is inserted, when the engaging part 1217 moves to the groove provided on the inner wall of the inlet pipe 111, the engaging part 1217 engages in the groove, and the partitions 1218 recover their deformation under the action of elastic force, thereby fixing the diversion bracket 120 in the inlet pipe 111. Then, the impeller 114 is installed below the diversion bracket 120.

[0088] The multiple engaging parts 1217 are preferably arranged at equal intervals to achieve uniform force distribution.

[0089] The diversion bracket 120 also includes a base 122, which is disposed at the second end 1215 of the body 121 and closes the second end 1215 of the body 121. The base 122 is provided with a drain outlet, which connects the inner cavity 1211 of the body 121 and the outer side of the body 121.

[0090] The base 122 seals the second end 1215 of the main body 121, and at the same time, the drain on the base 122 drains the water from the inner cavity 1211 of the main body 121, preventing water from stagnating in the inner cavity 1211 of the main body 121.

[0091] Alternatively, the base 122 may be omitted, and the second end 1215 of the body 121 may be sealed in another way.

[0092] Preferably, the drain outlet is located on the surface of the base 122 facing the body 121.

[0093] By placing the drain outlet on the surface of the base 122 facing the body 121, water flow can be prevented from directly impacting the other side of the base 122, thereby avoiding impact on the shaft 1141 and bushing 1142 of the impeller 114 of the water pump 100.

[0094] The drain outlet includes a plurality of drain holes 1221 evenly arranged along the circumference of the body 121. Of course, the invention is not limited to this, and those skilled in the art can also provide other forms of drain outlets as needed. The drain holes 1221 are inclined in the direction from the first end 1214 toward the second end 1215 and in the outer circumferential direction, thereby facilitating the discharge of fluid from the inner cavity 1211 of the body 121 in the direction of fluid flow.

[0095] The base 122 protrudes annularly outward relative to the body 121. This annular protrusion of the base 122 allows water to be briefly stored and stabilized within the inner cavity 1211 before flowing outward to the periphery and bottom. This ensures more even water flow in all directions towards the impeller 114, resulting in smoother operation of the impeller 114 without significant up-and-down swaying that could cause energy loss, thereby increasing the flow rate and head of the water pump 100.

[0096] A clearance groove 1222 is provided on the bottom surface of the base 122. The clearance groove 1222 is used to avoid the shaft 1141 of the impeller 114. The shaft 1141 of the impeller 114 is partially inserted into the clearance groove 1222, thereby avoiding the increase in the size of the water pump 100 due to the installation of the diversion bracket 120.

[0097] The diversion bracket 120 forms a generally cylindrical structure, and its inner cavity 1211 is also cylindrical. The cylindrical structure is adapted to the circular cross-section of the water inlet pipe 111 of the water pump 100. Of course, alternatively, the diversion bracket 120 can also be formed into other shapes. Those skilled in the art should understand that any shape can have a central axis extending from the first end 1214 toward the second end 1215, and has a circumferential direction and a diametrical direction centered on the central axis.

[0098] The fluid entering the pump 100 through the inlet pipe 111 first flows into the inner cavity 1211 of the body 121 of the diversion bracket 120 through the inlet 1212 of the diversion bracket 120, and then flows out through the flow channel 1216 on the side of the diversion bracket 120. This avoids direct impact on the shaft 1141 and bushing 1142 of the impeller 114. The water flow forms a rotation in the direction of the shaft 1141, giving the water a rotational speed in advance before it enters the impeller 114, reducing the resistance of the water entering the impeller 114, and ensuring that the water obtains more kinetic energy after entering the impeller 114.
