[0018] Figure 1 This is a cross-sectional view of an integrated water pump and fan structure according to an embodiment of the present invention; Figure 2 for Figure 1A partial enlarged view of the integrated water pump and fan structure shown; Figure 3 for Figure 1 A schematic diagram of a partition disk with an integrated water pump and fan structure; Figure 4 for Figure 1 The diagram shows the distribution of the first and second magnets on the mounting plate in the integrated water pump and fan structure. Figures 1-4 As shown, the integrated structure of the water pump and fan includes a water pump base 1, a drive assembly 2, an impeller 3, a shaft sleeve 4, a partition disk 5, a magnetic force generating device 6, a first engaging assembly 7, and a fan 8.
[0019] The pump base 1 has a receiving cavity, and the pump base 1 has a first opening 101 and a second opening communicating with the receiving cavity at opposite axial ends. The drive assembly 2 is disposed in the receiving cavity. The impeller 3 is driven to the end of the drive assembly 2 facing the first opening 101, and the pump base 1 has a drain outlet circumferentially corresponding to the impeller 3. The bushing 4 is driven to the end of the drive assembly 2 facing the second opening. The partition disk 5 is circumferentially fixedly connected to the bushing 4 and has a first magnetic isolation groove 51 through it. The magnetic force generating device 6 is disposed on the side of the partition disk 5 facing the first opening 101, and is connected to the inner cavity of the pump base 1. The wall is fixedly connected and is set corresponding to the first magnetic isolation groove 51; the first attraction component 7 is fitted with a bushing 4, is rotatably connected to the bushing 4, and extends to the side of the partition disk 5 facing the second opening, and is set corresponding to the magnetic force generating device 6. Under the action of the magnetic force generating device 6, it is attracted to the partition disk 5 or detached from the partition disk 5; the fan 8 includes a mounting plate 81 and fan blades 82 fixed to the circumference of the mounting plate 81. The mounting plate 81 is rotatably connected to the first attraction component 7, and a plurality of first magnets 9 are fixedly fixed circumferentially on the side surface facing the first attraction component 7. The first magnets 9 are set corresponding to the first attraction component 7.
[0020] In use, the drive assembly 2 and the magnetic force generating device 6 are activated. The drive assembly 2 drives the impeller 3 connected to it to rotate synchronously. The rotation of the impeller 3 creates a low-pressure zone at its center, causing external water to be drawn in through the first opening 101 under the action of pressure difference. The centrifugal force generated by the rotation of the impeller 3 throws the water from the center of the impeller 3 to the edge, and discharges it to the outside through the drain port on the water pump base 1. At the same time, the drive assembly 2 drives the bushing 4 connected to it to rotate synchronously. The rotation of the bushing 4 causes the partition disk 5 fixedly connected to it to rotate as well. The magnetic force generated by the magnetic force generating device 6 acts on the first attraction assembly 7, causing the first attraction assembly 7 to attract the partition disk 5. Thus, the first attraction assembly 7 rotates synchronously with the partition disk 5. During the rotation, the first attraction assembly 7 is magnetized by the first magnet 9 arranged circumferentially on the mounting plate 81. The rotating induced magnetic field generated by the magnetized first attraction assembly 7 generates torque with the first magnet 9, causing the mounting plate 81 to rotate at a different speed than the partition disk 5, which in turn drives the fan blade 82 fixedly connected to the mounting plate 81 to rotate, ultimately generating airflow.
[0021] By adopting the integrated structure of the water pump and fan of the present invention, the impeller 3 of the water pump and the fan blades 82 of the fan 8 can be driven to rotate simultaneously by the same set of drive components 2. Compared with the separate structure of water pump and fan 8, the structure is simplified, which helps to reduce the space occupied and reduce the difficulty of operation. After reducing the number of structural components, fewer parts need to be maintained, thus reducing the failure rate. Moreover, the drive component 2 indirectly drives the mounting plate 81 and the fan blades 82 to rotate through the partition disk 5 and the first suction component 7, so that the fan blades 82 and the impeller 3 can rotate at different speeds at the same time, which improves the flexibility of use.
[0022] like Figures 1-4 As shown, in this embodiment, the pump base 1 is a stepped hollow shell, symmetrically arranged about the axis. The cross-sectional diameter of the inner wall is larger at the left end and smaller at the right end. The pump base 1 has a first opening 101 at the right end and a second opening at the left end. The drive assembly 2 is coaxially arranged with the pump base 1 in the receiving cavity. The right end of the drive assembly 2 is driven by the impeller 3, and the left end is driven by the bushing 4. A circular spacer disk 5 is fitted on the outer wall of the bushing 4, and the spacer disk 5 is fixedly connected to the bushing 4 by a semi-circular key. The spacer disk 5 extends circumferentially towards the inner wall of the pump base 1 and is arranged perpendicular to the axis of the bushing 4. A first magnetic isolation groove 51 is formed through the spacer disk 5, corresponding to the magnetic force generating device 6. Figure 3 As shown, in this embodiment, the first magnetic isolation groove 51 is an arc-shaped hole, and multiple first magnetic isolation grooves 51 are spaced apart along the circumference of the magnetic disk 5. Figure 2 As shown, the width of the first magnetic isolation groove 51 is much larger than the gap between the disk 5 and the first attraction component 7, as well as the gap between the disk 5 and the magnetic force generating device 6. When the magnetic field generated by the magnetic force generating device 6 propagates along the disk 5 to the first magnetic isolation groove 51, the magnetic field bypasses the first magnetic isolation groove 51 and propagates along the first attraction component 7 because the magnetic permeability of the first attraction component 7 is much stronger than that of air. Finally, it returns to the magnetic force generating device 6 to form a loop. A magnetic force generating device 6 is disposed between the partition disk 5 and the drive assembly 2, and is circumferentially fixedly connected to the inner wall of the water pump base 1. A first engaging assembly 7 is fitted with a bushing 4 and extends circumferentially between the partition disk 5 and the fan 8, parallel to the partition disk 5. The mounting plate 81 of the fan 8 is rotatably connected to the first engaging assembly 7, and the mounting plate 81 is coaxially arranged with the bushing 4. On one side of the mounting plate 81 facing the first engaging assembly 7, multiple first magnets 9 are fixedly fixed circumferentially at intervals. The magnetic pole directions of all first magnets 9 are parallel to the axial direction of the mounting plate 81, and the magnetic pole directions of adjacent first magnets 9 are opposite. Figure 4As shown, the first magnet 9 is arranged in a ring near the axis of the mounting plate 81, with adjacent colors representing opposite magnetic pole directions. Multiple fan blades 82 are spaced apart circumferentially along the mounting plate 81. The magnetic force generating device 6 is a mature existing technology, and its specific structural composition can be selected as needed. The first attraction component 7 has a certain degree of elasticity, so when the magnetic force generating device 6 is activated, the first attraction component 7 is attracted to the partition disk 5 under the action of magnetic force. When the magnetic force generating device 6 is turned off, the magnetic force disappears, the first attraction component 7 disengages from the partition disk 5, and returns to its original position.
[0023] Optionally, the drive assembly 2 includes a fixed shaft 21, a rotor 22, a first bearing 23, a stator 24, and an isolation ring 25. The fixed shaft 21 is fixedly connected to the pump base 1; the rotor 22 is fitted onto the fixed shaft 21 and rotatably connected to it, and a permanent magnet 26 is circumferentially fixed to the rotor 22; the impeller 3 is fixedly connected to the end of the rotor 22 facing the first opening 101; the first bearing 23 is fitted onto the end of the rotor 22 facing the second opening and is fixedly connected to it; the first bearing 23 is fitted onto the end of the bushing 4 facing the first opening 101 and is fixedly connected to it; the stator 24 surrounds the rotor 22 and is fixedly connected to the inner wall of the pump base 1; the isolation ring 25 is circumferentially fixed to the inner wall of the pump base 1 at the end of the stator 24 facing the first opening 101, inserted between the stator 24 and the permanent magnet 26, and extends to be fixedly connected to the outer ring of the first bearing 23. This configuration simplifies the structural composition of the drive assembly 2 and facilitates assembly and operation.
[0024] like Figure 1 and Figure 2 As shown, in this embodiment, the fixed shaft 21 is coaxially arranged with the water pump base 1 and is fixedly connected to the water pump base 1. The rotor 22 is sleeved on the outer wall of the fixed shaft 21, and the two are rotatably connected. The end of the rotor 22 facing the second opening, that is... Figure 1 A first bearing 23 is fitted onto the outer wall of the left end of the rotor 22, and the left end of the first bearing 23 is simultaneously fitted onto the outer wall of the bushing 4, and is fixedly connected to the bushing 4. The end of the rotor 22 facing the first opening 101, that is... Figure 1An impeller 3 is fixedly connected to the right end of the rotor 22. A permanent magnet 26 is fitted onto the outer wall of the rotor 22, and an isolation ring 25 is circumferentially fitted around the permanent magnet 26, with a certain gap between the isolation ring 25 and the permanent magnet 26. The isolation ring 25 includes a fixed section and an isolation section connected vertically. The fixed section is perpendicular to the axis of the water pump base 1, and its outer wall is circumferentially fixedly connected to the inner wall of the water pump base 1. The isolation section is parallel to the axis of the water pump base 1 and surrounds the permanent magnet 26. The inner wall of the left end of the isolation section is fixedly connected to the outer ring of the first bearing 23. The stator 24 is located in the space between the outer wall of the isolation ring 25 and the inner wall of the water pump base 1. Under the isolation effect of the isolation ring 25, the water flow entering through the first opening 101 is isolated in the space enclosed by the water pump base 1, the isolation ring 25, the first bearing 23, and the rotor 22, so that the water flow will not flow into the space where the stator 24, the magnetic force generating device 6, the partition disk 5, and the first attraction assembly 7 are located. The stator 24 is wound with coils around its circumference. When the coils are energized, the permanent magnet 26 on the rotor 22 cooperates with the stator 24 to provide a deflection force, driving the rotor 22 to rotate. The rotation of the rotor 22 drives the impeller 3, which is fixedly connected to it, to rotate. The rotation of the impeller 3 draws in external water through the first opening 101, and under the centrifugal force generated by the rotation of the impeller 3, it is thrown to the edge and discharged to the outside through the drain port on the water pump base 1. At the same time, the rotation of the rotor 22 drives the inner ring of the first bearing 23, which is fixedly connected to it, to rotate, and in turn, the inner ring of the first bearing 23 drives the bushing 4, which is fixedly connected to it, to rotate synchronously. The process of driving the rotor 22 to rotate is a mature existing technology, and its specific principle will not be elaborated here.
[0025] Optionally, the magnetic force generating device 6 includes a toroidal iron core 61 and a first coil 62. The toroidal iron core 61 is fitted with a first bearing 23, fixedly connected to the outer ring of the first bearing 23, and circumferentially fixed to the inner wall of the water pump base 1. A first annular groove is formed on the surface of the toroidal iron core 61 facing the magnetic disk 5. The first coil 62 is disposed within the first annular groove and corresponds to the first magnetic isolation groove 51. This configuration simplifies the structural composition of the magnetic force generating device 6 and facilitates assembly and operation.
[0026] like Figure 1 and Figure 2As shown, in this embodiment, the annular iron core 61 is fitted with a first bearing 23 and is fixedly connected to the outer ring of the first bearing 23, and is coaxially arranged with the bushing 4. A coaxial first annular groove is opened on the left end face of the annular iron core 61, and a first coil 62 is arranged in the first annular groove. Corresponding to the circumferential direction of the first coil 62, a plurality of first magnetic isolation grooves 51 are spaced apart on the spacer disk 5, and the first magnetic isolation grooves 51 are arc-shaped holes. When the rotor 22 rotates, driving the bushing 4 and the spacer disk 5, which are directly or indirectly fixed to it, to rotate, the first coil 62 is energized. The energized first coil 62 generates a magnetic field, which magnetically attracts the first engaging component 7 on the other side of the spacer disk 5, causing the first engaging component 7 to engage with the spacer disk 5 and rotate synchronously with it. Furthermore, under the torque generated by the first magnet 9, it drives the mounting disk 81 and the fan blade 82 to rotate. When the first coil 62 is de-energized, the magnetic field disappears, the attraction to the first engaging component 7 disappears, the first engaging component 7 detaches from the spacer disk 5, and can no longer rotate synchronously with it. Consequently, the mounting disk 81 and the fan blade 82 stop rotating. The first coil 62 is connected to an external control circuit via wires to control its energization or de-energization; this is mature existing technology, and its specific control circuit will not be described in detail here.
[0027] Optionally, the first engaging assembly 7 includes a first transmission disk 71, a first elastic element 72, and a first clutch disk 73. The first transmission disk 71 is fitted with a bushing 4 and is rotatably connected to the bushing 4, extending to the side of the spacer disk 5 facing the second opening and correspondingly positioned with the first coil 62. The mounting disk 81 is rotatably connected to the first transmission disk 71. The first elastic element 72 is fixedly connected to the surface of the first transmission disk 71 facing the first coil 62. The first clutch disk 73 is fixedly connected to the surface of the first elastic element 72 facing the first coil 62. This configuration simplifies the structure of the first engaging assembly 7, ensuring both a stable relative position with the bushing 4 and the ability to engage or disengage with the spacer disk 5.
[0028] like Figure 1 and Figure 2As shown, in this embodiment, a second bearing 15 is fitted and fixed on the outer wall of the left end of the bushing 4. The first transmission disk 71 includes a first fixing ring parallel to the axis of the bushing 4 and a first transmission ring perpendicular to the axis of the bushing 4. The first fixing ring is fitted with the second bearing 15 and fixedly connected to the outer ring of the second bearing 15. The first transmission ring extends circumferentially from the first fixing ring toward one end of the partition disk 5, and extends toward the inner wall of the water pump base 1 and parallel to the partition disk 5, and covers the projection of the first coil 62 on the partition disk 5. The first elastic member 72 is fixedly connected to the side surface of the first transmission ring facing the first coil 62, that is, the right side surface of the first transmission ring. The first clutch disk 73 is fixedly connected to the side surface of the first elastic member 72 facing the first coil 62, that is, the right side surface of the first elastic member 72, and maintains a certain gap with the partition disk 5. A third bearing 16 is fitted and fixed to the outer wall of the first fixing ring of the first transmission disk 71, which is fitted with the bushing 4. The mounting disk 81 of the fan 8 is fixedly connected to the outer ring of the third bearing 16, realizing a rotatable connection between the mounting disk 81 and the first transmission disk 71. After the first coil 62 is energized, the magnetic field generated by the first coil 62 acts on the first clutch disk 73, which is in clearance with the spacer disk 5, causing the first clutch disk 73 to tend to move towards the spacer disk 5. The first elastic element 72 undergoes elastic deformation, eventually causing the first clutch disk 73 to be attracted to the spacer disk 5 and rotate synchronously with the spacer disk 5, thereby driving the first elastic element 72 and the first transmission disk 71 to rotate accordingly. After the first coil 62 is de-energized, the magnetic field disappears, the first elastic element 72 recovers its deformation, and the first clutch disk 73 is disengaged from the spacer disk 5 and returns to its initial position. Depending on the actual application, the specific shape and size of the first transmission disk 71, the first elastic element 72 and the first clutch disk 73 can be adjusted. As long as the first transmission disk 71 can be stably sleeved on the bushing 4, the first elastic element 72 will deform under the action of elastic force after the first coil 62 is energized to generate a magnetic field, so that the first clutch disk 73 can be attracted to the partition disk 5, thereby driving the first transmission disk 71 to rotate synchronously.
[0029] Figure 5 for Figure 1The diagram shows an exploded view of the second engaging assembly of the integrated pump and fan structure. Optionally, the annular core 61 has a second annular groove on its surface facing the spacer disk 5. The second annular groove is located on the side of the first annular groove away from the first bearing 23, and the second coil 63 is disposed within the second annular groove. The spacer disk 5 has a second magnetic isolation groove 52, which corresponds to the second coil 63. The integrated pump and fan structure also includes a second engaging assembly 10, which includes a second transmission disk 1001, a second elastic element 1002, and a second clutch disk 1003. The second transmission disk 1001 is fitted onto the spacer disk 5 and engages with the spacer disk 5. The first drive disk 1001 is rotatably connected to and extends to the side of the partition disk 5 facing the second opening, and is correspondingly arranged with the second coil 63. The second elastic member 1002 is fixedly connected to the surface of the second drive disk 1001 facing the second coil 63. The second clutch disk 1003 is fixedly connected to the surface of the second elastic member 1002 facing the second coil 63. A plurality of second magnets 11 are fixedly fixed circumferentially on the surface of the mounting disk 81 facing the partition disk 5. The second magnets 11 are arranged corresponding to the second drive disk 1001, and the number of second magnets 11 is greater than the number of first magnets 9. With this arrangement, different speed requirements for the fan 8 can be achieved by means of the first engaging component 7 and the second engaging component 10.
[0030] like Figure 1 and Figure 2 As shown, in this embodiment, a second annular groove is formed on the left end face of the toroidal core 61, and the second annular groove is located on the side of the first annular groove away from the first bearing 23. The two are coaxially arranged, and a certain distance is maintained between the first annular groove and the second annular groove to prevent the magnetic fields generated by the first coil 62 and the second coil 63 from mutually conducting magnetism. Figure 3 As shown, multiple second magnetic isolation slots 52 are spaced through the circumference of the second coil 63 on the partition disk 5, and the second magnetic isolation slots 52 extend in an arc shape for a certain distance. The width of the second magnetic isolation slots 52 is much larger than the gap between the second clutch disk 1003 and the partition disk 5, and the gap between the second coil 63 and the partition disk 5. Their working principle is the same as that of the first magnetic isolation slot 51. Between the first magnetic isolation slot 51 and the second magnetic isolation slot 52, multiple third magnetic isolation slots 53 are also spaced through the circumference of the partition disk 5, similarly preventing the magnetic fields generated by the first coil 62 and the second coil 63 from mutually conducting magnetism. Figure 2 and Figure 5As shown, a fourth bearing 17 is fitted and fixed to the outer wall of the partition disk 5. The second transmission disk 1001 includes a second fixing ring 10011 parallel to the axis of the bushing 4 and a second transmission ring 10012 perpendicular to the axis of the bushing 4. The second fixing ring 10011 is fitted with the fourth bearing 17 and fixedly connected to the outer ring of the fourth bearing 17. The second transmission ring 10012 extends circumferentially from the second fixing ring 10011 toward one end of the fan 8 and extends parallel to the partition disk 5 toward the bushing 4, covering the second coil 63. Projected onto the spacer disk 5, the second elastic element 1002 is fixedly connected to the side surface of the second transmission ring 10012 facing the second coil 63, that is, the right side surface of the second transmission ring 10012. Three second elastic elements 1002 are spaced apart and evenly distributed circumferentially along the right side surface of the second transmission ring 10012. The second clutch disk 1003 is fixedly connected to the side surface of the second elastic element 1002 facing the second coil 63, that is, the right side surface of the second elastic element 1002, and maintains a certain gap with the spacer disk 5. Figure 4 As shown, on the side surface of the mounting plate 81 of the fan 8 facing the spacer disk 5, a plurality of second magnets 11 are fixed circumferentially. The magnetic poles of all the second magnets 11 are parallel to the axis of the mounting plate 81, and the magnetic poles of adjacent second magnets 11 are opposite. After the control coil 63 is energized, the magnetic field generated by the second coil 63 acts on the second clutch disk 1003, causing the second clutch disk 1003 to tend to move toward the spacer disk 5. The second elastic element 1002 undergoes elastic deformation, and finally the second clutch disk 1003 is attracted to the spacer disk 5 and rotates synchronously with the spacer disk 5. This, in turn, drives the second elastic element 1002 and the second transmission disk 1001 to rotate. During the rotation, the second transmission disk 1001 is magnetized by the second magnets 11 arranged circumferentially on the mounting plate 81. The rotating induced magnetic field generated by the magnetized second transmission disk 1001 generates torque with the second magnets 11, causing the mounting plate 81 to rotate at a speed different from that of the rotor 22. Because the number of second magnets 11 is greater than the number of first magnets 9, the torque generated is greater. Therefore, when the second coil 63 is energized alone, the fan 8 rotates faster than when the first coil 62 is energized alone.
[0031] By using the cooperation of the first coil 62 and the second coil 63, different speeds of the fan 8 can be driven as needed: (i) When the first coil 62 and the second coil 63 are not energized, the rotor 22 rotates, which drives the impeller 3 to rotate, and at the same time drives the bushing 4 and the partition disk 5 to rotate. However, the first clutch disk 73 and the second clutch disk 1003 are not engaged with the partition disk 5 and cannot rotate. At this time, the fan 8 does not rotate. (ii) When the first coil 62 is energized and the second coil 63 is not energized, when the rotor 22 rotates, it drives the impeller 3 to rotate, and at the same time drives the bushing 4 and the partition disk 5 to rotate. The first clutch disk 73 is attracted to the partition disk 5 under the action of the magnetic field generated by the first coil 62, while the second clutch disk 1003 is not attracted to the partition disk 5. The first clutch disk 73 drives the first transmission disk 71 to rotate synchronously. The first transmission disk 71 is magnetized by the first magnet 9. The rotating induced magnetic field generates torque with the first magnet 9, which drives the fan 8 to rotate at low speed differential speed. (III) When the first coil 62 is not energized and the second coil 63 is energized, the rotor 22 rotates, which drives the impeller 3 to rotate, and at the same time drives the bushing 4 and the partition disk 5 to rotate. The first clutch disk 73 is not attracted to the partition disk 5. The second clutch disk 1003 is attracted to the partition disk 5 under the action of the magnetic field generated by the second coil 63, which drives the second transmission disk 1001 to rotate synchronously. The second transmission disk 1001 is magnetized by the second magnet 11. The rotating induced magnetic field generates torque with the second magnet 11, which drives the fan 8 to rotate at medium speed differential speed. (iv) When the first coil 62 and the second coil 63 are both energized, the rotor 22 rotates, which drives the impeller 3 to rotate, and at the same time drives the bushing 4 and the partition disk 5 to rotate. The first clutch disk 73 is attracted to the partition disk 5 under the action of the magnetic field generated by the first coil 62, which drives the first transmission disk 71 to rotate synchronously. The first transmission disk 71 is magnetized by the first magnet 9. The rotating induced magnetic field generates torque with the first magnet 9. The second clutch disk 1003 is attracted to the partition disk 5 under the action of the magnetic field generated by the second coil 63, which drives the second transmission disk 1001 to rotate synchronously. The second transmission disk 1001 is magnetized by the second magnet 11. The rotating induced magnetic field generates torque with the second magnet 11. The two torques are superimposed, which drives the fan 8 to rotate at high speed differential speed.
[0032] Optionally, the integrated pump and fan structure also includes multiple reduction magnet assemblies 12, which are arranged circumferentially around the second transmission disk 1001. Each reduction magnet assembly 12 includes a third magnet 121 and a fourth magnet 122 arranged opposite to each other. The third magnet 121 is fixed to the second transmission disk 1001, and the fourth magnet 122 is fixed to the inner wall of the pump base 1. When the partition disk 5 rotates with the bushing 4, the second transmission disk 1001 may rotate slightly due to friction between components. The above arrangement, with the help of the reduction magnet assemblies 12, ensures that the second transmission disk 1001 remains stationary when the second coil 63 is not energized.
[0033] like Figure 1 and Figure 2As shown, in this embodiment, the second transmission disk 1001 and the partition disk 5 are rotatably connected by the fourth bearing 17. When the partition disk 5 rotates with the bushing 4 and thus drives the inner ring of the fourth bearing 17 to rotate, the outer ring may rotate due to the friction between the inner and outer rings, and drive the second transmission disk 1001 to rotate. The magnetic pole direction of the deceleration magnet group 12 is parallel to the direction of the fan axis, and the magnetic pole directions of the third magnet 121 and the fourth magnet 122 are the same. They attract each other. Under the attraction of the third magnet 121 and the fourth magnet 122 in the same deceleration magnet group 12, the rotation trend of the second transmission disk 1001 is counteracted. In this embodiment, the deceleration magnet assembly 12 is disposed on a set of surfaces opposite to the inner wall of the second transmission disk 1001 and the water pump base 1 along the axis of the rotor 22. Depending on the actual application, the deceleration magnet assembly 12 can also be disposed on other opposing surfaces of the second transmission disk 1001 and the inner wall of the water pump base 1. The number of deceleration magnet assemblies 12 can also be adjusted as needed. As long as the second transmission disk 1001 can remain stationary when the second coil 63 is not energized under the magnetic force of the deceleration magnet assembly 12, and the normal rotation of the second transmission disk 1001 is not affected when the second coil 63 is energized.
[0034] Optionally, the integrated pump and fan structure also includes a first sealing ring 13, which is disposed between the rotor 22 and the first bearing 23. This arrangement seals any gap that may exist between the inner rings of the rotor 22 and the first bearing 23, preventing water entering through the first opening 101 from flowing into the space on one side of the partition disk 5 along the gap.
[0035] like Figure 1 and Figure 2 As shown, the first sealing ring 13 surrounds the rotor 22 and is embedded between the rotor 22 and the inner ring of the first bearing 23.
[0036] Optionally, the integrated pump and fan structure also includes a second sealing ring 14, which is disposed between the isolation ring 25 and the first bearing 23. This arrangement, by means of the second sealing ring 14, seals any gaps that may exist between the outer ring of the isolation ring 25 and the first bearing 23, preventing water entering through the first opening 101 from flowing into the space of the isolation ring 25 facing the stator 24.
[0037] like Figure 1 and Figure 2 As shown, the second sealing ring 14 surrounds the first bearing 23 and is embedded between the outer ring of the first bearing 23 and the isolation ring 25.
[0038] Optionally, the fan 8 also includes a protective frame 83, which covers the fan blades 82 and the mounting plate 81 and is fixedly connected to the water pump base 1. This arrangement, by using the protective frame 83 to cover the fan blades 82 and the mounting plate 81, prevents the fan blades 82 from damaging other components during rotation and also prevents damage to the fan blades 82.
[0039] The present invention also provides a vehicle comprising the integrated structure of water pump and fan as described in any of the above embodiments.
[0040] The vehicle using this invention can simultaneously drive the impeller 3 of the water pump and the blades 82 of the fan 8 using the same drive assembly 2. Compared with the separate structure of the water pump and the fan 8, the structure is simplified, which helps to reduce the space occupied and reduce the difficulty of operation. Moreover, after reducing the number of structural components, fewer parts need to be maintained, thus reducing the failure rate. Furthermore, the drive assembly 2 indirectly drives the mounting plate 81 and the blades 82 to rotate through the partition disk 5 and the first engaging assembly 7, so that the blades 82 and the impeller 3 can rotate at different speeds at the same time, which improves the flexibility of use.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
