Description

Technical Field

[0001] This invention relates to the field of water pump technology, specifically a water pump. Background Technology

[0002] A water pump is a machine that transports or pressurizes liquids. A water pump typically includes components such as a pump body, impeller, motor, and sealing structure. It can transfer the mechanical energy of a prime mover or other external energy to a liquid, increasing the liquid's energy. It is mainly used to transport liquids. Water pumps can be used in washing machines to quickly drain water from the drum during the washing or spin-drying stages.

[0003] In actual use, water often contains debris such as fibers and hair. These small debris can easily enter the drainage pump and become entangled in the impeller or shaft, leading to a decrease in drainage efficiency, or even causing pump jamming or motor overload, affecting the safety and reliability of the entire machine. Summary of the Invention

[0004] The technical problem to be solved by the present invention is water pump blockage, and a water pump is provided.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: including a driving component, a pump body device and a sealing device, wherein the driving component is connected to a control system; the driving component includes a motor.

[0006] The pump body assembly includes a cleaning mechanism, a drainage mechanism, and a connecting mechanism. The cleaning mechanism is installed on one side of the drive component, and the sealing device is installed inside the connecting mechanism. The cleaning mechanism can remove small impurities that are entangled in the impeller and shaft, preventing impurities from affecting the rotation of the impeller. The drainage mechanism can discharge water, and the connecting mechanism is used to install the sealing device.

[0007] The drainage mechanism includes a water outlet component, which is installed at one end of a support component. The support component is installed on one side of a debris removal mechanism. A water inlet component is installed at one end of the water outlet component, and the water inlet component is installed on one side of a connecting mechanism. Water enters through the water inlet component and exits through the water outlet component.

[0008] The impurity removal mechanism includes a support assembly mounted on a drive unit. A transmission assembly is installed inside the support assembly and is mounted at the output end of the drive unit. A switching assembly is mounted on one side of the transmission assembly, and a linkage assembly is mounted on the other side of the switching assembly. The transmission assembly converts the forward rotation transmitted by the motor into bidirectional rotation. The support assembly supports the transmission assembly. The switching assembly switches the direction of rotation output to the linkage assembly according to the rotational speed. The linkage assembly outputs the direction of rotation transmitted by the switching assembly.

[0009] The switching assembly includes a sliding element and a fixed element. The sliding element slides on the linkage assembly, and the fixed element is installed between the transmission assembly and the linkage assembly. A wedge-shaped element is slidably installed inside the sliding element. When the impeller rotates normally, the fixed element drives the sliding element to rotate, and the sliding element drives the linkage assembly to rotate. When the impeller speed decreases, the sliding element slides on the fixed element, the transmission assembly drives the sliding element to rotate in the opposite direction, and the sliding element drives the linkage assembly to rotate in the opposite direction.

[0010] The sliding element includes a sliding bushing that slides on a fixed element. A first friction disc is mounted on one side of the sliding bushing. A transmission groove is provided inside the sliding bushing, a rotating groove is provided on one side of the transmission groove, a spline groove is provided on one side of the rotating groove, and a moving groove is provided on the other side of the transmission groove. The wedge-shaped element slides in the moving groove. When the impeller rotates normally, the wedge-shaped element leaves the surface of the wedge block, and the fixed block is located in the transmission groove. The transmission rod drives the fixed block to rotate, the fixed block drives the sliding bushing to rotate, and the sliding bushing drives the linkage assembly to rotate. When the impeller speed decreases, the wedge-shaped element presses against the surface of the wedge block, and the wedge-shaped element drives the sliding bushing to move closer to the motor. The fixed block leaves the transmission groove and is now located in the rotating groove. The first friction disc abuts against the transmission assembly, and the transmission assembly drives the first friction disc to rotate in the opposite direction. The first friction disc drives the sliding bushing to rotate in the opposite direction, and the sliding bushing drives the linkage assembly to rotate in the opposite direction.

[0011] The fixed element includes a transmission rod that rotates on a linkage assembly. A fixed block is mounted on the outer side of the transmission rod, located within a rotating groove. A wedge-shaped block is mounted on one side of the transmission rod, also mounted on the transmission assembly. After impurities are removed from the impeller or shaft, the impeller's speed returns to normal, the wedge-shaped element returns to its initial position, and the linkage assembly drives the sliding sleeve to move away from the motor until the fixed block leaves the rotating groove and enters the transmission groove. The fixed block then drives the sliding sleeve to rotate forward.

[0012] The wedge element includes a wedge-shaped column that slides within a moving groove. A wedge head is mounted on one side of the wedge-shaped column, located at the wedge block. A limit block is mounted on the outer side of the wedge-shaped column. A first elastic element is sleeved on the wedge-shaped column, with one end mounted on the limit block and the other end mounted on the moving groove. The first elastic element includes a first spring. When the impeller rotates normally, the wedge-shaped column is subjected to centrifugal force, causing it to move away from the drive rod within the moving groove. The wedge-shaped column drives the wedge head away from the surface of the wedge block. When the impeller rotates and descends, the first spring stretches, causing the wedge-shaped column to move closer to the drive rod. The wedge-shaped column causes the wedge head to press against the wedge block, and the wedge-shaped column causes the sliding bushing to move closer to the motor.

[0013] The transmission assembly includes a rotating shaft mounted on the output end of the drive component. A wedge block is mounted on the rotating shaft, and a first bevel gear is mounted on the rotating shaft. A support plate is mounted on a support assembly, and the rotating shaft rotates on the support plate. An outer shaft and a third bevel gear are rotatably mounted on the support plate, meshing with the first and third bevel gears. A second bevel gear is mounted on the outer shaft, meshing with the third bevel gear. A second friction disc is mounted on the outer shaft. A motor drives the rotating shaft to rotate, which in turn drives the first bevel gear and the wedge block to rotate. The first bevel gear drives the third bevel gear to rotate, which in turn drives the second bevel gear to rotate. The second bevel gear drives the outer shaft to rotate, and the outer shaft drives the second friction disc to rotate.

[0014] The linkage assembly includes a linkage sleeve, within which a transmission rod rotates. A spline is mounted on the linkage sleeve, located within a spline groove. A limit plate is also mounted on the linkage sleeve. A second elastic element is sleeved on the linkage sleeve, with one end mounted on the limit plate and the other end mounted on a sliding sleeve. An impeller is mounted on one side of the linkage sleeve. The second elastic element includes a second spring. When the impeller rotates normally, the sliding sleeve drives the linkage sleeve to rotate, which in turn drives the impeller to rotate. When the impeller speed decreases, the sliding sleeve slides away from the impeller on the linkage sleeve.

[0015] The water outlet assembly includes a water outlet chamber, which is installed on one side of the support assembly. A water outlet pipe is installed on the water outlet chamber, and the impeller is located inside the water outlet chamber. The water inlet assembly includes an inlet chamber mounted on a connecting mechanism, and an inlet pipe installed on the inlet chamber. Water enters the inlet chamber through the inlet pipe, flows through the filter plate into the outlet chamber, and the impeller discharges the water from the outlet pipe.

[0016] The sealing device includes a sealing plate that rotates within a connecting mechanism. A connecting plate is mounted on one side of the sealing plate, a guide plate is mounted on one side of the connecting plate, and a filter plate is mounted on the guide plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This invention employs automatic anti-clogging technology, which automatically detects the pump impeller's rotational speed through a mechanical structure, thereby enabling real-time identification of clogging conditions. When the impeller is entangled with debris, it controls the impeller to briefly rotate in the opposite direction, generating torque and instantaneous impact force opposite to the original forward rotation. This breaks the mechanical balance formed by the entanglement of the foreign object during forward rotation, causing the debris entangled in the impeller or shaft to loosen or detach. Simultaneously, the reverse water flow smoothly carries the loosened foreign object away from the impeller area and out of the pump body, preventing impeller jamming or motor overload, and improving the safety and reliability of the pump operation.

The support component is installed on one side of the impurity removal mechanism 21. A water inlet component 222 is installed at one end of the water outlet component 221, and the water inlet component 222 is installed on one side of the connecting mechanism 23. Water enters through the water inlet component 222 and exits through the water outlet component 221.

[0024] The impurity removal mechanism 21 includes a support assembly mounted on the drive member 1. A transmission assembly 212 is installed inside the support assembly and is mounted at the output end of the drive member 1. A switching assembly 211 is mounted on one side of the transmission assembly 212, and a linkage assembly 213 is mounted on the other side of the switching assembly 211. The transmission assembly 212 can convert the forward rotation transmitted by the motor into bidirectional rotation. The support assembly supports the transmission assembly 212. The switching assembly 211 can switch the direction of rotation output to the linkage assembly 213 according to the rotational speed. The linkage assembly 213 can output the direction of rotation transmitted by the switching assembly 211.

[0025] The switching assembly 211 includes a sliding element 2111 and a fixed element 2112. The sliding element 2111 slides on the linkage assembly 213. The fixed element 2112 is installed between the transmission assembly 212 and the linkage assembly 213. The sliding element 2111 slides on the fixed element 2112, and a wedge-shaped element 2113 is slidably installed inside the sliding element 2111. When the impeller 2133 rotates normally, the fixed element 2112 drives the sliding element 2111 to rotate, and the sliding element 2111 drives the linkage assembly 213 to rotate. When the speed of the impeller 2133 decreases, the sliding element 2111 slides on the fixed element 2112, the transmission assembly 212 drives the sliding element 2111 to rotate in the opposite direction, and the sliding element 2111 drives the linkage assembly 213 to rotate in the opposite direction.

[0026] The sliding element 2111 includes a sliding bushing 21111, which slides on the fixed element 2112. A first friction disc 21115 is installed on one side of the sliding bushing 21111.

When the impeller 2133 rotates normally, the wedge element 2113 moves away from the surface of the wedge block 21121, and the fixed block 21123 is located in the transmission groove 21112. The transmission rod 21122 drives the fixed block 21123 to rotate, the fixed block 21123 drives the sliding bushing 21111 to rotate, and the sliding bushing 21111 drives the linkage assembly 213 to rotate. When the speed of the impeller 2133 decreases, the wedge element 2113 presses against the surface of the wedge block 21121, and the wedge element 2113... 113 drives the sliding bushing 21111 to move closer to the motor, and the fixed block 21123 leaves the transmission groove 21112. At this time, the fixed block 21123 is located in the rotating groove 21113. The first friction disc 21115 abuts against the transmission assembly 212.

The first friction disc 21115 drives the sliding bushing 21111 to rotate in the opposite direction. The sliding bushing 21111 drives the linkage assembly 213 to rotate in the opposite direction.

[0027] The fixed element 2112 includes a transmission rod 21122, which rotates on the linkage assembly 213. A fixing block 21123 is installed on the outer side of the transmission rod 21122, and the fixing block 21123 is located in the rotation groove 21113. A wedge block 21121 is installed on one side of the transmission rod 21122, and the wedge block 21121 is installed on one side of the transmission assembly 212. After the impurities in the impeller 2133 or the shaft are removed, the rotation speed of the impeller 2133 returns to normal, the wedge element 2113 returns to its initial position, and the linkage assembly 213 drives the sliding sleeve 21111 to move away from the motor until the fixing block 21123 leaves the rotation groove 21113. The fixing block 21123 then enters the transmission groove 21112, and the fixing block 21123 drives the sliding sleeve 21111 to rotate in the forward direction.

[0028] The wedge element 2113 includes a wedge post 21131 that slides in a moving groove. A wedge head 21132 is installed on one side of the wedge post 21131 and is located at the wedge block 21121. A limit block is installed on the outside of the wedge post 21131. A first elastic element 21133 is sleeved on the wedge post 21131. One end of the first elastic element 21133 is installed on the limit block, and the other end of the first elastic element 21133 is installed on the moving groove. The first elastic element 21133 includes a first spring. When the impeller 2133 rotates normally, the wedge column 21131 is subjected to centrifugal force. The wedge column 21131 moves away from the transmission rod 21122 in the moving groove. The wedge column 21131 drives the wedge head 21132 to leave the surface of the wedge block 21121. When the impeller 2133 rotates and descends, the first spring stretches and drives the wedge column 21131 to move closer to the transmission rod 21122. The wedge column 21131 drives the wedge head 21132 to squeeze the wedge block 21121. The wedge column 21131 drives the sliding bushing 21111 to move closer to the motor.

The first bevel gear 2122 drives the third bevel gear 2126 to rotate, which in turn drives the second bevel gear 2124 to rotate. The second bevel gear 2124 drives the outer shaft 2125 to rotate, which in turn drives the second friction disk 2127 to rotate. When the first friction disk 21115 abuts against the second friction disk 2127, the second friction disk 2127 drives the first friction disk 21115 to rotate in the opposite direction. The first friction disc 21115 drives the sliding bushing 21111 to rotate in the opposite direction. The sliding bushing 21111 drives the connecting bushing 2131 to rotate in the opposite direction. The connecting bushing 2131 drives the impeller 2133 to rotate in the opposite direction, causing the impeller to generate torque and instantaneous impact force opposite to the original forward rotation. This can break the entanglement mechanical balance formed by foreign objects during forward rotation, causing the debris entangled in the impeller or shaft to loosen or detach. At the same time, the reverse water flow smoothly carries the loosened foreign objects away from the impeller area and discharges them from the pump body, preventing impeller jamming or motor overload.

[0030] The linkage assembly 213 includes a linkage bushing 2131, a transmission rod 21122 that rotates within the linkage bushing 2131, a spline mounted on the linkage bushing 2131, the spline located within a spline groove 21114, a limit plate 2134 mounted on the linkage bushing 2131, a second elastic element 2132 sleeved on the linkage bushing 2131, one end of the second elastic element 2132 mounted on the limit plate 2134, and the other end of the second elastic element 2132 mounted on a sliding bushing 21111, and an impeller 2133 mounted on one side of the linkage bushing 2131. The second elastic element 2132 includes a second spring. When the impeller 2133 rotates normally, the sliding bushing 21111 drives the connecting bushing 2131 to rotate, and the connecting bushing 2131 drives the impeller 2133 to rotate. When the speed of the impeller 2133 decreases, the sliding bushing 21111 slides away from the impeller 2133.

[0031] The water outlet assembly 221 includes a water outlet chamber 2211, which is installed on one side of the support assembly. A water outlet pipe 2212 is installed on the water outlet chamber 2211, and an impeller 2133 is located inside the water outlet chamber 2211. The water inlet assembly 222 includes an inlet chamber 2221, which is mounted on the connecting mechanism 23. An inlet pipe 2222 is installed on the inlet chamber 2221. Water enters the inlet chamber 2221 through the inlet pipe 2222, flows through the filter plate 34 to the outlet chamber 2211, and the impeller 2133 discharges the water from the outlet pipe 2212.

[0032] The sealing device 3 includes a sealing plate 31, which rotates within the connecting mechanism 23. A connecting plate 32 is installed on one side of the sealing plate 31, and a guide plate 33 is installed on one side of the connecting plate 32. A filter plate 34 is installed on the guide plate 33.

[0033] Working principle of the invention: When the water pump is in use, the motor drives the rotating shaft 2121 to rotate. The rotating shaft 2121 drives the first bevel gear 2122 and the wedge block 21121 to rotate. The first bevel gear 2122 drives the third bevel gear 2126 to rotate. The third bevel gear 2126 drives the second bevel gear 2124 to rotate. The second bevel gear 2124 drives the outer shaft 2125 to rotate. The outer shaft 2125 drives the second friction disc 2127 to rotate. The rotating shaft 2121 drives the wedge block 21121 to rotate. The wedge block 21121 drives the transmission rod 21122 to rotate. 1122 drives the fixed block 21123 to rotate. At this time, the wedge element 2113 leaves the surface of the wedge block 21121. The fixed block 21123 is located in the transmission groove 21112. The fixed block 21123 drives the sliding bushing 21111 to rotate. The sliding bushing 21111 drives the connecting bushing 2131 to rotate. The connecting bushing 2131 drives the impeller 2133 to rotate. Water enters the inlet chamber 2221 from the inlet pipe 2222. The water flows through the filter plate 34 to the outlet chamber 2211. The impeller 2133 discharges the water from the outlet pipe 2212.

[0034] When the impeller 2133 or shaft of the water pump is entangled with small impurities, the rotational speed of the impeller 2133 will decrease. The first spring stretches, causing the wedge-shaped column 21131 to move closer to the transmission rod 21122. The wedge-shaped column 21131 drives the wedge-shaped head 21132 to press against the wedge block 21121. The wedge-shaped column 21131 drives the sliding bushing 21111 to move closer to the motor. The fixed block 21123 leaves the transmission groove 21112. At this time, the fixed block 21123 is located in the rotating groove 21113. The first friction disc 21115 abuts against the second friction disc 2127. 2127 drives the first friction disc 21115 to rotate in the opposite direction, the first friction disc 21115 drives the sliding bushing 21111 to rotate in the opposite direction, the sliding bushing 21111 drives the connecting bushing 2131 to rotate in the opposite direction, and the connecting bushing 2131 drives the impeller 2133 to rotate in the opposite direction, so that the impeller generates torque and instantaneous impact force opposite to the original forward rotation, which can break the entanglement mechanical balance formed by foreign objects during forward rotation, so that the debris entangled in the impeller or shaft is loosened or detached. At the same time, the loosened foreign objects are smoothly carried away from the impeller area and discharged from the pump body by the reverse water flow, preventing the impeller from jamming or the motor from overloading.

[0035] After the impurities in the impeller 2133 or shaft are removed, the rotational speed of the impeller 2133 returns to normal, the wedge element 2113 returns to its initial position, the second spring is compressed and drives the sliding sleeve 21111 to move away from the motor, the first friction disc 21115 leaves the surface of the second friction disc 2127 until the fixed block 21123 leaves the rotating groove 21113, the fixed block 21123 enters the transmission groove 21112, the fixed block 21123 drives the sliding sleeve 21111 to rotate in the forward direction, the sliding sleeve 21111 drives the connecting sleeve 2131 to rotate in the forward direction, the connecting sleeve 2131 drives the impeller 2133 to rotate in the forward direction, the impeller 2133 works normally and continues to discharge the water in the water inlet chamber 2221.
