Description

Technical Field

[0001] This utility model relates to an anti-clogging rotor, and also to a water pump. Background Technology

[0002] Submersible pumps are commonly used in aquariums for water purification and pet water fountains. Submersible pumps typically use a motor to drive an impeller to rotate within the working chamber, drawing water in from the inlet and pumping it out from the outlet. In existing submersible pumps, the impeller is usually mounted directly on the motor shaft, which creates a gap between the impeller and the motor. After prolonged operation, dirt, hair, and other debris can easily become entangled in this gap, causing the impeller to rotate unevenly.

[0003] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0004] To address the technical problem mentioned above in the prior art where, after prolonged operation, dirt, hair, and other debris easily become entangled in the gap between the impeller and the motor, causing the impeller to rotate unevenly, the technical solution adopted by this utility model is: an anti-clogging rotor, comprising: a base, a rotating shaft, and an impeller. The rotating shaft is rotatably connected to the base. The impeller includes: a rotating wheel and multiple blades connected to the rotating wheel. The rotating wheel has a circular groove. The base has a connecting positioning part rotatably connected to the side wall of the groove. The rotating shaft passes through the connecting positioning part. One end of the rotating shaft has a driving component. The groove has a blocking block that cooperates with the driving component to drive the rotating shaft to rotate the impeller. A permanent magnet is connected to the rotating shaft.

[0005] As described above, in the anti-clogging rotor, the sidewall of the groove is provided with an annular groove, and the connecting positioning part is provided with an annular protrusion that can be inserted into the annular groove, and the annular protrusion is rotatably connected to the annular groove.

[0006] In the anti-clogging rotor described above, a sealing ring is provided between the rotating shaft and the connecting positioning part.

[0007] As described above, in an anti-clogging rotor, the blocking block has a fan-shaped cross-section, and the bottom surface of the groove is provided with a positioning groove into which the blocking block can be inserted, with one end of the blocking block located in the positioning groove.

[0008] As described above, in an anti-clogging rotor, the blocking block is made of an elastic material.

[0009] As described above, in the anti-clogging rotor, the base is provided with a bushing for positioning the rotating shaft.

[0010] This utility model discloses a water pump, comprising: a pump casing, an impeller cover, an anti-clogging rotor as described above, and a motor winding. The pump casing is provided with a mounting groove for installing the anti-clogging rotor. The base of the anti-clogging rotor is connected to the pump casing.

[0015] 2. In this embodiment, the cross-section of the blocking block is fan-shaped, and the bottom surface of the groove is provided with a positioning groove into which the blocking block can be inserted. One end of the blocking block is located in the positioning groove. With this design, the rotor has an angle of "no-load" stroke when starting. At the same time, the blocking block can be made of elastic material, such as silicone or rubber, which can further reduce the vibration and noise of the water pump during operation.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1 to 5 As shown, an anti-clogging rotor of this embodiment includes: a base 11, a rotating shaft 12, and an impeller 13. The rotating shaft 12 is rotatably connected to the base 11. The impeller 13 includes: a rotating wheel 131 and multiple blades 132 connected to the rotating wheel 131. The rotating wheel 131 is provided with a circular groove 13101. The base 11 is provided with a connecting positioning part 111 rotatably connected to the side wall of the groove 13101. The rotating shaft 12 passes through the connecting positioning part 111. One end of the rotating shaft 12 is provided with a driving member 121. The groove 13101 is provided with a blocking block 133 that cooperates with the driving member 121 to drive the rotating shaft 12 to rotate the impeller 13. A permanent magnet 14 is connected to the rotating shaft 12. The anti-clogging rotor of this utility model has a connecting and positioning part on the base that is rotatably connected to the side wall of the groove. At the same time, the rotating shaft passes through the connecting and positioning part, which can minimize the gap between the impeller and the base, prevent dirt, hair and other debris from entering the gap between the impeller and the base, and thus enable the impeller to rotate smoothly relative to the base.

[0028] To achieve a rotatable connection between the impeller's rotating wheel and the connecting positioning part, an annular groove 13102 is provided on the side wall of the groove 13101, and an annular protrusion 1111 is provided on the connecting positioning part 111 that can be engaged with the annular groove 13102. The annular protrusion 1111 is rotatably connected to the annular groove 13102. The rotatable connection between the rotating wheel and the connecting positioning part is achieved through the cooperation of the annular groove and the annular protrusion. Because the edge of the annular protrusion 1111 has rounded corners or chamfers, external force is applied to make the annular protrusion 1111 engage with the annular groove 13102. Similarly, the annular groove can also be provided on the connecting positioning part 111, and the annular protrusion 1111 can be provided on the side wall of the groove 13101.

[0029] In order to improve the sealing effect between the rotating shaft 12 and the connecting positioning part 111, a sealing ring 122 is provided between the rotating shaft 12 and the connecting positioning part 111.

[0030] In this embodiment, the blocking block 133 has a fan-shaped cross-section, and the bottom surface of the groove 13101 is provided with a positioning groove 13103 into which the blocking block 133 can be inserted. One end of the blocking block 133 is located in the positioning groove 13103. With this design, the rotor has an angled "no-load" stroke during startup. At the same time, the blocking block 133 can be made of an elastic material, such as silicone or rubber, which can further reduce vibration and noise during pump operation.

[0031] In order to make the shaft rotate more smoothly, a bushing 15 for positioning the shaft 12 is provided on the base 11.

[0032] This embodiment of a water pump includes: a pump casing 2, an impeller cover 3, an anti-clogging rotor 1 as described above, and a motor winding 4. The pump casing 2 has a mounting groove 200 for mounting the anti-clogging rotor 1. The base 11 of the anti-clogging rotor 1 is connected to the pump casing 2. The impeller cover 3 is connected to the pump casing 2. A working chamber 201 is provided between the pump casing 2 and the impeller cover 3. The impeller 13 of the anti-clogging rotor 1 is located within the working chamber 201. The impeller cover 3 has an inlet 202 communicating with the working chamber 201. The pump casing 2 has an outlet 203 communicating with the working chamber 201. The motor winding 4 is connected to the pump casing 2 to drive the anti-clogging rotor 1 to rotate. This utility model's water pump uses an anti-clogging rotor, allowing the impeller to rotate smoothly and preventing dirt from clogging the gap between the impeller and the base. It also has the advantages of low vibration and low noise.

[0033] In this embodiment, a filter grille 5 is connected to the pump casing 2 and located outside the impeller cover 3. The filter grille 5 is used to filter out dirt in the water.

[0034] A suction cup 6 is provided on the filter screen 5 to facilitate the positioning of the water pump.
