Description

Technical Field

[0001] The present disclosure relates to the technical field of cleaning equipment, and more particularly, to a filtering and cleaning module and a laundry treatment device. Background Art

[0002] With the improvement of living standards, there have emerged many household appliances with a drying function to dry objects, providing great convenience for people's lives. In household appliances that use a dehumidifying agent with heat desorption performance, such as molecular sieves, as a dehumidification module, after the dry air passes through the object to be dried, it takes away the moisture in the object to be dried and becomes high-humidity air; the high-humidity air passes through the dehumidification module, is re-dried after absorbing moisture, and is then re-transported back to the object to be dried for dehumidification; the heating module extracts the moisture in the dehumidification module, thereby forming a drying cycle.

[0003] Existing drying modules usually need to transmit the humid gas to be dried through a filtering and cleaning module. However, the existing filtering and cleaning modules have a relatively high failure rate, affecting the user experience.

[0060] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. Like reference numerals in the figures denote like or similar structures, and thus their detailed descriptions will be omitted.

It can be understood that if the device of the icon is turned upside down, the component described as "upper" will become the component described as "lower". When a structure is "on" another structure, it may mean that a structure is integrally formed on another structure, or that a structure is "directly" disposed on another structure, or that a structure is "indirectly" disposed on another structure through another structure.

[0062] The terms "a", "an", "the", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "comprising" and "having" are used to mean an open inclusion and refer to the possibility of the existence of additional elements / components / etc. in addition to the listed elements / components / etc.; the terms "first", "second", "third", etc. are used only as labels and do not limit the quantity of their objects.

[0063] In an embodiment of the present disclosure, as Figures 1 to 3 shown, the laundry treatment device includes a filter cleaning module 10, a laundry treatment drum 20 and a drying module 30. An air inlet and an air outlet are provided on the laundry treatment drum 20. The air inlet of the drying module 30 is communicated with the air outlet of the laundry treatment drum 20 through the filter cleaning module 10, and the air outlet of the drying module 30 is communicated with the air inlet of the laundry treatment drum 20, so as to continuously dehydrate the gas in the laundry treatment drum 20 through the drying module 30, and form a circulating air flow between the laundry treatment drum 20 and the drying module 30, thereby achieving the purpose of drying the laundry in the laundry treatment drum 20.

[0064] Generally, the wet air from the laundry treatment drum 20 will carry some impurities such as lint shed from the laundry. If these impurities such as lint are not filtered, the wet air will carry these impurities into the drying module 30 and adhere to the drying module 30, thereby causing blockage of the drying module 30, and even possibly the lint adhering to the drying module 30 may be ignited when heated, causing damage to the drying module 30.

[0065] Therefore, when the moisture in the laundry treatment drum 20 enters the drying module 30 through the filter cleaning module 10, the filter element 112 in the filter cleaning module 10 usually filters impurities such as lint.

[0066] However, after the laundry treatment device has been used for a long time, more and more impurities such as lint will adhere to the filter element 112 provided in the air duct 113 of the filter cleaning module 10; if the filter element 112 is not cleaned for a long time, the impurities such as lint adhering to it will block the gas flow in the air duct 113 of the filter cleaning module 10, thereby affecting the drying efficiency of the laundry treatment device.

[0067] In response to this, as Figures 2 to 4As shown in the figure, the filtration and cleaning module 10 provided by the present disclosure includes a filtration module 110, a drive module 120, and a spraying module 130. The filtration module 110 includes a filtration housing 111 and a filtration element 112. The filtration housing 111 forms an air duct 113 having an air inlet and an air outlet. The filtration element 112 is disposed in the air duct 113 for filtering the gas passing through the air duct 113. The drive module 120 includes a drive motor assembly and a motor housing 121. The drive motor assembly is received in the motor housing 121, and a rotating shaft 122 of the drive motor assembly extends out through a through hole on the motor housing 121. The spraying module 130 includes a spraying assembly and a water supply assembly. A plurality of spraying holes 1313 for spraying the filtration element 112 are provided on the spraying assembly. The water supply assembly is communicated with the plurality of spraying holes 1313 on the spraying assembly. One end of the spraying assembly is connected to the rotating shaft 122 of the drive motor assembly to rotate under the drive of the rotating shaft 122 of the drive motor assembly. The water supply assembly includes a water inlet 132. The water inlet 132 is located between the spraying assembly and the motor housing 121, and the water inlet 132 is fixedly arranged relative to the motor housing 121.

[0068] A moisture circulation channel is formed between the laundry treatment drum 20 or the drying module 30 through the filtration housing 111. The filtration element 112 can filter impurities such as lint in the moisture passing through the air duct 113 in the filtration housing 111. When there are too many impurities such as lint on the filtration element 112, or when the filtration element 112 needs to be cleaned regularly, the filtration element 112 can be flushed through the provided spraying module 130, so that the cleaning liquid sprayed out through the spraying holes 1313 of the spray pipe 131 can remove the impurities attached to the filtration element 112, thereby ensuring the gas circulation in the air duct 113 of the filtration and cleaning module 10 and avoiding affecting the drying efficiency of the laundry treatment equipment due to filtering impurities such as lint in the moisture.

[0069] However, during the process of the drive motor assembly in the drive module 120 driving the spraying assembly to rotate and spray the filtration element 112, there is a phenomenon that the cleaning liquid flows all the way up along the rotating shaft 122 to reach the drive motor, resulting in safety problems for the drive motor.

[0070] In response to this, as Figure 5 shown, the drive module 120 provided by the present disclosure further includes a motor seal ring 123. The motor seal ring 123 is disposed at the through hole of the motor housing 121 to seal the gap between the rotating shaft 122 and the motor housing 121 at the through hole. By providing the motor seal ring 123, the sealing effect between the rotating shaft 122 of the drive motor assembly and the motor housing 121 is improved. When the cleaning liquid flows all the way up along the rotating shaft 122 to reach the rotating shaft 122 of the drive motor assembly, the motor seal ring 123 can effectively prevent the cleaning liquid from entering the interior of the motor housing 121 through the gap between the rotating shaft 122 and the motor housing 121, thereby improving the safety and service life of the drive motor assembly.

[0071] Among them, the motor sealing ring 123 can be a rubber sealing ring. The edge of the motor sealing ring 123 can be stuck on the edge of the through hole of the motor housing 121, so as to form a limit for the motor sealing ring 123 in the axial direction of the rotating shaft 122, improve the stability of the motor sealing ring 123, and further improve the sealing effect of the gap between the rotating shaft 122 and the motor housing 121.

[0072] Among them, the motor sealing ring 123 is sleeved on the rotating shaft 122. The through hole of the motor sealing ring 123 through which the rotating shaft 122 passes can be in interference fit with the rotating shaft 122, so that the motor sealing ring 123 is closely attached to the surface of the rotating shaft 122, further improving the sealing effect; by using a rubber sealing ring, through the self-deformation of the rubber sealing ring, the fitting effect between the motor sealing ring 123 and the surface of the rotating shaft 122 can be further improved.

[0073] In some embodiments, as Figures 6 to 9 shown, the filter housing 111 is provided with a through hole 1115. The rotating shaft 122 is connected to the spray pipe 131 located in the air duct 113 through the through hole 1115, that is, the driving module 120 can be set such that only one end of the rotating shaft 122 passes through the filter housing 111 and extends into one side of the air duct 113, and the motor housing 121 and the driving motor assembly are located outside the filter housing 111.

[0074] Among them, a first sealing ring 141 is sleeved on the rotating shaft 122. The first sealing ring 141 is used to seal the gap between the rotating shaft 122 and the filter housing 111 at the through hole 1115, and the gap between the motor housing 121 and the opposite surfaces of the filter housing 111 at the through hole 1115. By providing the first sealing ring 141, a seal between the rotating shaft 122 and the filter housing 111 is formed, so as to effectively prevent the cleaning liquid from reaching one side of the motor housing 121 through the gap between the rotating shaft 122 and the filter housing 111.

[0075] In some embodiments, on the surface of the first sealing ring 141 facing the motor housing 121, there is at least one annular sealing rib surrounding the rotating shaft 122, or on the surface of the first sealing ring 141 facing the filter housing 111, there is at least one annular sealing rib surrounding the rotating shaft 122, or on the surface of the first sealing ring 141 facing the motor housing 121 and the surface facing the filter housing 111, there are at least one annular sealing rib surrounding the rotating shaft 122.

[0076] In some embodiments, as Figure 10As shown, on the surface of the first sealing ring 141 facing the motor housing 121, there is provided at least one first annular sealing rib 1411, and at least one first annular sealing rib 1411 is arranged around the rotating shaft 122. When the first sealing ring 141 is in close fit with the motor housing 121, the raised first annular sealing rib 1411 can further improve the fit degree between the first sealing ring 141 and the motor housing 121, thereby enhancing the sealing effect between the first sealing ring 141 and the motor housing 121. By providing the first annular sealing rib 1411 on the first sealing ring 141, through designing the mold, the first sealing ring 141 with the first annular sealing rib 1411 can be formed by the same process when forming the first sealing ring 141, reducing the production cost. Among them, the first sealing ring 141 can be provided with one, two or more first annular sealing ribs 1411. When there are multiple first annular sealing ribs 1411, the first annular sealing ribs 1411 with different diameters can be concentrically distributed.

[0077] In some embodiments, on the surface of the motor housing 121 facing the first sealing ring 141, there can also be provided at least one first annular protrusion, and at least one first annular protrusion is arranged around the rotating shaft 122. When the motor housing 121 is in close fit with the first sealing ring 141, the first annular protrusion can further improve the fit degree between the motor housing 121 and the first sealing ring 141, thereby enhancing the sealing effect between the motor housing 121 and the first sealing ring 141. Among them, the motor housing 121 can be provided with one, two or more first annular protrusions. When there are multiple first annular protrusions, the first annular protrusions with different diameters can be concentrically distributed.

[0078] Among them, at least one first annular sealing rib 1411 can be provided only on the first sealing ring 141, or at least one first annular protrusion can be provided only on the motor housing 121, or at least one first annular sealing rib 1411 is provided on the first sealing ring 141 and at least one first annular protrusion is provided on the motor housing 121 at the same time. When at least one first annular sealing rib 1411 is provided on the first sealing ring 141 and at least one first annular protrusion is provided on the motor housing 121 at the same time, the first annular sealing rib 1411 and the first annular protrusion are arranged in a staggered manner in the radial direction of the rotating shaft 122 to avoid the overlapping of positions from affecting the sealing effect.

[0079] In some embodiments, at least one second annular sealing rib is provided on the surface of the first sealing ring 141 facing the filter housing 111, and at least one second annular sealing rib is arranged around the rotating shaft 122. When the first sealing ring 141 is in close fit with the filter housing 111, the raised second annular sealing rib can further improve the fit degree of the first sealing ring 141 and the filter housing 111, thereby improving the sealing effect between the first sealing ring 141 and the filter housing 111. By designing a mold, the first sealing ring 141 with the second annular sealing rib can be formed in the same process when the first sealing ring 141 is formed, reducing the production cost. The first sealing ring 141 may be provided with one, two or more second annular sealing ribs. When there are multiple second annular sealing ribs, the second annular sealing ribs with different diameters may be concentrically distributed.

[0080] In some embodiments, as Figure 11 shown, at least one second annular protrusion 1116 may also be provided on the surface of the filter housing 111 facing the first sealing ring 141, and at least one second annular protrusion 1116 is arranged around the rotating shaft 122. When the filter housing 111 is in close fit with the first sealing ring 141, the raised second annular protrusion 1116 can further improve the fit degree of the filter housing 111 and the first sealing ring 141, thereby improving the sealing effect between the filter housing 111 and the first sealing ring 141. The filter housing 111 may be provided with one, two or more second annular protrusions 1116. When there are multiple second annular protrusions 1116, the second annular protrusions 1116 with different diameters may be concentrically distributed.

[0081] Among them, at least one second annular sealing rib may be provided only on the first sealing ring 141, or at least one second annular protrusion 1116 may be provided only on the filter housing 111, or at least one second annular sealing rib is provided on the first sealing ring 141 and at least one second annular protrusion 1116 is provided on the filter housing 111 at the same time. When at least one second annular sealing rib is provided on the first sealing ring 141 and at least one second annular protrusion 1116 is provided on the filter housing 111 at the same time, the second annular sealing rib and the second annular protrusion 1116 are arranged in a staggered manner in the radial direction of the rotating shaft 122 to avoid overlapping positions from affecting the sealing effect.

[0082] In some embodiments, as Figure 11As shown, a counterbore surrounding the through-hole 1115 is provided at the position of the through-hole 1115 on the filter housing 111, and the part of the first sealing ring 141 located between the motor housing 121 and the water inlet 132 on the opposite surfaces of the through-hole 1115 is located in the counterbore. By assembling the first sealing ring 141 in the counterbore on the filter housing 111, a limit on the first sealing ring 141 in the radial direction of the rotating shaft 122 is formed, which can improve the fitting degree between the first sealing ring 141, the filter housing 111 and the motor housing 121, and thus improve the waterproof performance.

[0083] Among them, when a second annular protrusion 1116 is provided on the filter housing 111, the second annular protrusion 1116 is located in the counterbore. The depth of the counterbore in the axial direction of the rotating shaft 122 is less than the thickness of the first sealing ring 141, so that the first sealing ring 141 is closely attached to the filter housing 111 and the motor housing 121; the size and shape of the counterbore match the first sealing ring 141 to form an assembly positioning for the first sealing ring 141, and at the same time avoid squeezing the first sealing ring 141 in the free state.

[0084] In some embodiments, as Figure 12 shown, the spray pipe 131 is provided with a first flow channel 1314 and a second flow channel 1315 which are arranged at intervals in the radial direction of the rotating shaft 122. Some of the plurality of spray holes 1313 communicate with the first flow channel 1314, and the rest communicate with the second flow channel 1315. Among them, the spray holes 1313 communicating with the first flow channel 1314 and the spray holes 1313 communicating with the second flow channel 1315 are arranged in parallel or at intervals in the rotation direction.

[0085] Specifically, the first flow channel 1314 extends along the axial direction of the spray pipe 131, the second flow channel 1315 extends along the axial direction of the spray pipe 131, and the first flow channel 1314 and the second flow channel 1315 are arranged at intervals in the radial direction of the spray pipe 131. The plurality of spray holes 1313 on the spray pipe 131 communicating with the first flow channel 1314 are arranged at intervals along the axial direction of the spray pipe 131, and the plurality of spray holes 1313 are located at the same position in the circumferential direction of the spray pipe 131 on the spray pipe 131; the plurality of spray holes 1313 on the spray pipe 131 communicating with the second flow channel 1315 are arranged at intervals along the axial direction of the spray pipe 131, and the plurality of spray holes 1313 are located at the same position in the circumferential direction of the spray pipe 131 on the spray pipe 131.

[0086] Among them, after a plurality of spray holes 1313 on the spray pipe 131 that communicate with the first flow channel 1314 and the second flow channel 1315 are arranged at intervals along the axial direction of the spray pipe 131, a row of spray holes 1313 is formed; in the height direction of the filter element 112, this row of spray holes 1313 can generally cover the filter element 112, and through the rotation of the spray pipe 131, the plurality of spray holes 1313 communicating with the first flow channel 1314 can clean various positions of the filter element 112 in the width direction.

[0087] In some embodiments, as Figure 12 shown, the spray pipe 131 includes a first sub-spray pipe 1311 and a second sub-spray pipe 1312 connected together along its axial direction. After the first sub-spray pipe 1311 and the second sub-spray pipe 1312 are butted, they can be detachably connected together by bolts. The spray pipes 131 on the first sub-spray pipe 1311 and the second sub-spray pipe 1312 can be arranged in alignment, that is, two opposite rows of spray holes 1313 can be arranged on the first sub-spray pipe 1311 and the second sub-spray pipe 1312.

[0088] In some embodiments, as Figure 13 shown, the filter module 110 further includes a bracket 1113. The bottom of the second sub-spray pipe 1312 can be supported on the bracket 1113 and can rotate relative to the bracket 1113, thereby forming the assembly of both ends of the spray pipe 131 in its axial direction and improving the stability of its rotation process.

[0089] In some embodiments, as Figure 13 shown, the filter housing 111 includes an outer housing 1111 and an inner housing 1112. The outer housing 1111 and the inner housing 1112 are snapped together to form the filter housing 111. The outer housing 1111 forms an air duct 113, the inner housing 1112 is arranged in the inner housing 1112, a bracket 1113 is arranged on the inner housing 1112, and the filter element 112 and the spray pipe 131 are assembled on the bracket 1113 of the inner housing 1112. After the moisture enters the air duct 113 between the outer housing 1111 and the inner housing 1112, it passes through the filter element 112 and then enters the side where the spray pipe 131 is provided, and then enters the drying module 30.

[0090] Among them, when assembling the drive module 120 and the spray module 130, the drive module 120 can be fixed on the outer housing 1111, and a through hole 1115 is provided on the outer housing 1111 for the rotating shaft 122 to pass through; the water inlet 132 of the spray module 130 can be arranged on the side of the inner housing 1112 away from the outer housing 1111 to be located in the air duct 113; the water inlet 132 can be fixedly connected to the inner housing 1112, and the part of the outer housing 1111 and the inner housing 1112 that fixes the drive module 120 and the spray module 130 is clamped between the water inlet 132 and the motor housing 121.

[0091] In some embodiments, as Figure 13 shown, a seal 1114 is further provided on the filter housing 111. By providing the seal 1114, the sealing performance between the filter housing 111 and the target part during assembly is formed, so as to avoid air leakage in the air duct 113.

[0092] In some embodiments, as Figure 14 shown, a water storage space 1322 is formed on one side of the water inlet 132 along the axial direction of the rotating shaft 122 close to the filter housing 111. The water storage space 1322 is communicated with the air duct 113 outside the water inlet 132 through an overflow channel on the water inlet 132. By providing the water storage space 1322 on the water inlet 132, after the filter cleaning module 10 is used for a long time, when the first sealing ring 141 or the second sealing ring 142 fails due to a fault or a service life problem, the cleaning liquid that reaches the side of the water inlet 132 close to the inner shell 1112 along the transmission shaft 125 can be received in the water storage space 1322, so as to avoid the continuous upward spread of the cleaning liquid, and further avoid the cleaning liquid from entering the drive motor assembly.

[0093] At the same time, in order to ensure sufficient connection stability between the water inlet 132 and the inner shell 1112, the water inlet 132 and the inner shell 1112 are tightly abutted against each other in a circumferential circle. At this time, the cleaning liquid in the water storage space 1322 cannot flow out smoothly to the outside of the water inlet 132. Through the overflow channel provided on the water inlet 132, the water storage space 1322 can be communicated with the air duct 113 outside the water inlet 132, so as to timely discharge the accumulated cleaning liquid in the water storage space 1322, and further avoid the continuous upward spread of the cleaning liquid after the water storage space 1322 is filled with the cleaning liquid.

[0094] Among them, as Figure 14 shown, a groove 1323 is provided on the edge of the water inlet 132 close to the inner shell 1112. The groove 1323 serves as the overflow channel. When there is more cleaning liquid in the water storage space 1322, the cleaning liquid can flow out of the water storage space 1322 through the groove 1323. Of course, the overflow channel can also be a through hole provided on the water inlet 132; when multiple overflow channels are provided, the overflow channel can be a groove 1323 provided on the edge of the water inlet 132 close to the inner shell 1112, or a through hole provided on the water inlet 132, or include both the groove 1323 and the through hole at the same time. The present disclosure does not limit this.

[0095] In some embodiments, as Figure 15As shown, in the axial direction of the rotating shaft 122, there is a height difference h between the bottom of the groove 1323 away from the motor housing 121 and the end of the rotating shaft 122, that is, the lowest point of the overflow channel away from the motor housing 121 is lower than the lowest point of the rotating shaft 122 on the side facing the water inlet device. When the cleaning liquid overflows and flows out through the overflow channel, the liquid level height of the cleaning liquid is less than that of the rotating shaft 122 at this time and will not soak the rotating shaft 122, so that the cleaning liquid will not spread along the rotating shaft 122 to the drive motor assembly, ensuring the safety of the drive module 120.

[0096] In some embodiments, as Figure 16 shown, a water storage space 1324 is formed on one side of the water inlet device 132 along the axial direction of the rotating shaft 122 close to the spray pipe 131. After the cleaning liquid to be cleaned entering through the water inlet 1321 enters the water storage space 1324, it then enters the spray pipe 131 after being buffered by the water storage space 1324. By setting the water storage space 1324, a buffer area for the cleaning liquid is formed in the water inlet device 132, so that the cleaning liquid entering the spray pipe 131 can contain as few bubbles as possible, thereby improving the cleaning effect on the filter element 112 through the spray holes 1313.

[0097] In some embodiments, the water supply assembly further includes a water distribution member, and the water outlet of the water inlet device 132 is communicated with the water inlet hole of the water distribution member; during the rotation of the spray pipe 131, the water outlet hole of the water distribution member is communicated with the first flow channel 1314 or the second flow channel 1315.

[0098] Specifically, as Figures 17 to 20 shown, the water distribution member includes a first water distribution piece 133 and a second water distribution piece 134 stacked together along the axial direction of the rotating shaft 122. The first water distribution piece 133 is provided with a water outlet hole 1331 and is fixedly arranged on the water inlet device 132, and the cleaning liquid in the water inlet device 132 flows out through the water outlet hole 1331; the second water distribution piece 134 is provided with a first water distribution hole 1341 and a second water distribution hole 1342 and is fixedly arranged on the water inlet 1321 of the spray pipe 131. The first water distribution hole 1341 is communicated with the first flow channel 1314, and the second water distribution hole 1342 is communicated with the second flow channel 1315.

[0099] Among them, the first water distribution piece 133 is fixedly arranged on the water inlet device 132 and will not rotate with the rotation of the rotating shaft 122, and is fixedly arranged relative to the rotating shaft 122; the second water distribution piece 134 is fixedly arranged on the spray pipe 131 and rotates with the rotation of the spray pipe 131; therefore, the second water distribution piece 134 rotates relative to the first water distribution piece 133. During the rotation, one of the first water distribution hole 1341 and the second water distribution hole 1342 on the second water distribution piece 134 will have an overlapping part with the water outlet hole 1331, that is, one of the first water distribution hole 1341 and the second water distribution hole 1342 is communicated with the water outlet hole 1331, and the other is blocked from the water outlet hole 1331.

[0100] Therefore, during the rotation of the spray pipe 131, the first flow channel 1314 and the second flow channel 1315 take turns to admit water, that is, the spray holes 1313 communicating with the first flow channel 1314 and the second flow channel 1315 take turns to spray liquid. By making the spray holes 1313 communicating with the first flow channel 1314 and the second flow channel 1315 take turns to spray liquid, when the spray holes 1313 communicating with the first flow channel 1314 correspond to the filter element 112, the filter element 112 is spray-cleaned through the spray holes 1313 on the first flow channel 1314. At this time, no cleaning liquid is introduced into the second flow channel 1315, and the spray holes 1313 communicating with the second flow channel 1315 do not perform spray operations, saving cleaning liquid; when the spray holes 1313 communicating with the second flow channel 1315 correspond to the filter element 112, the filter element 112 is spray-cleaned through the spray holes 1313 on the second flow channel 1315. At this time, no cleaning liquid is introduced into the first flow channel 1314, and the spray holes 1313 communicating with the first flow channel 1314 do not perform spray operations, so as to have sufficient spray water volume during a single spray and improve the cleaning effect.

[0101] In some embodiments, such as Figure 17 and Figure 18 shown, a first protrusion 1332 and a first recess 1333 are provided on the side edge of the first water distribution piece 133. The first water distribution piece 133 is fixed on the inner wall of the water inlet device 132, that is, a groove 1323 corresponding to the first protrusion 1332 and a protrusion corresponding to the first recess 1333 can be correspondingly provided on the inner wall of the water inlet device 132, so as to form a positioning assembly between the first water distribution piece 133 and the water inlet device 132, and at the same time form a fixed installation of the first water distribution piece 133 relative to the water inlet device 132.

[0102] In some embodiments, such as Figures 19 to 21 shown, a second recess 1343 is provided on the side edge of the second water distribution piece 134. The second water distribution piece 134 is fixed on the spray pipe 131, and a second protrusion 1317 corresponding to the second recess 1343 is provided on the spray pipe 131, so as to form a positioning assembly between the second water distribution piece 134 and the spray pipe 131, and at the same time form a fixed installation of the second water distribution piece 134 relative to the spray pipe 131.

[0103] In some embodiments, the driving module 120 further includes a driving connecting piece 124 and a transmission shaft 125. The driving connecting piece 124 is provided with a first mounting hole and a second mounting hole which are arranged in a partitioned manner. The transmission shaft 125 extends into the first mounting hole to be connected with the driving connecting piece 124; a through hole is provided on the water inlet device 132, the transmission shaft 125 is arranged in the through hole, one end of the transmission shaft 125 extends out of the through hole and extends into the second mounting hole to be connected with the driving connecting piece 124, and the other end extends out of the through hole to be connected with the spray module 130.

[0104] Wherein, the drive shaft 125 and the rotating shaft 122 are connected to opposite ends of the drive connector 124, and the outer peripheral surface of the drive shaft 125 is directly connected to the drive connector 124 to improve the sealing performance at the connection between the outer peripheral surface of the drive shaft 125 and the drive connector 124; and / or, the outer peripheral surface of the rotating shaft 122 is directly connected to the drive connector 124 to improve the sealing performance at the connection between the outer peripheral surface of the rotating shaft 122 and the drive connector 124.

[0105] Wherein, the drive shaft 125 and the rotating shaft 122 are connected to opposite ends of the drive connector 124, and the bushing holes for installing the drive shaft 125 and the rotating shaft 122 on the drive connector 124 can be communicated or partitioned; partitioning the bushing holes for installing the drive shaft 125 and the rotating shaft 122 can further prevent the cleaning liquid from spreading upward from the drive connector 124 and improve the waterproof performance.

[0106] However, since the first water dividing piece 133, the second water dividing piece 134 and the water inlet device 132 are sleeved on the drive shaft 125, during the process of the drive shaft 125 driving the spray pipe 131 to rotate and spray the filter element 112, there is a phenomenon that the cleaning liquid flows upward along the drive shaft 125 all the way to the drive motor, resulting in safety problems for the drive motor.

[0107] In response to this, in some embodiments, as Figure 22 shown, a second sealing ring 142 is provided between the first water dividing piece 133 and the water inlet device 132. The second sealing ring 142 is used to seal the gap between the part of the first water dividing piece 133 other than the water outlet hole 1331 and the opposite surface of the water inlet device 132. A first water passing hole 1421 corresponding to the water outlet hole 1331 is provided on the second sealing ring 142 to conduct the water outlet hole 1331 and the first water dividing hole 1341 or the second water dividing hole 1342. By providing the second sealing ring 142, the gap between the part of the first water dividing piece 133 other than the water outlet hole 1331 and the opposite surface of the water inlet device 132 is sealed. That is, the part of the second sealing ring 142 surrounding the drive shaft 125 can be regarded as the second sealing ring 142 being sleeved on the drive shaft 125. The gap communicating with the drive shaft 125 between the first water dividing piece 133 and the water inlet device 132 is blocked by the part of the first sealing ring 141 sleeved on the drive shaft 125, forming a seal for the gap communicating with the drive shaft 125 between the first water dividing piece 133 and the water inlet device 132. Therefore, when the cleaning liquid enters the first water dividing hole 1341 or the second water dividing hole 1342 through the water outlet hole 1331, the cleaning liquid can be prevented from entering the drive shaft 125.

[0108] In some embodiments, as Figure 23As shown, a third sealing ring 143 is provided between the second water dividing piece 134 and the spray pipe 131. The third sealing ring 143 is used to seal the gap between the surface of the part of the second water dividing piece 134 other than the first water dividing hole 1341 and the second water dividing hole 1342 and the opposite surface of the spray pipe 131. The third sealing ring 143 is provided with second water passing holes 1431 corresponding to the first water dividing hole 1341 and the second water dividing hole 1342 to conduct the first water dividing hole 1341 and the first flow channel 1314, and the second water dividing hole 1342 and the second flow channel 1315. By providing the third sealing ring 143, the gap between the surface of the part of the second water dividing piece 134 other than the water outlet hole 1331 and the opposite surface of the spray pipe 131 is sealed. That is, the part of the third sealing ring 143 surrounding the transmission shaft 125 can be regarded as the third sealing ring 143 being sleeved on the transmission shaft 125. The gap between the second water dividing piece 134 and the spray pipe 131 communicating with the transmission shaft 125 is blocked by the part of the second sealing ring 142 sleeved on the transmission shaft 125, forming a seal for the gap between the second water dividing piece 134 and the spray pipe 131 communicating with the transmission shaft 125. Therefore, when the cleaning liquid enters the first flow channel 1314 through the first water dividing hole 1341 or enters the second flow channel 1315 through the second water dividing hole 1342, the cleaning liquid can be prevented from entering the transmission shaft 125.

[0109] By providing the motor sealing ring 123, the first sealing ring 141, the second sealing ring 142 and the third sealing ring 143, it is equivalent to setting four blocking parts on the path where the cleaning liquid flows along the rotating shaft 122 and the transmission shaft 125 all the way up to the driving motor, which can thoroughly improve this phenomenon and improve the safety and service life of the driving motor assembly.

[0110] In some embodiments, as Figure 24 and Figure 25 shown, a third recessed part 1422 is provided on the side of the second sealing ring 142. The second sealing ring 142 is fixed in the water inlet device 132. That is, a protrusion 1325 corresponding to the third recessed part 1422 can be provided on the inner wall of the water inlet device 132, so as to form a positioning assembly between the second sealing ring 142 and the water inlet device 132, and at the same time form a fixed installation of the second sealing ring 142 relative to the water inlet device 132.

[0111] In some embodiments, as Figure 26 and Figure 27 shown, a fourth recessed part 1432 is provided on the side of the third sealing ring 143. The third sealing ring 143 is fixed on the spray pipe 131. The spray pipe 131 is provided with a second protrusion part 1317 corresponding to the fourth recessed part 1432, so as to form a positioning assembly between the third sealing ring 143 and the spray pipe 131, and at the same time form a fixed installation of the third sealing ring 143 relative to the spray pipe 131.

[0112] In some embodiments, such as Figure 26 and Figure 27 shown, on the side of the third sealing ring 143 facing the spray pipe 131, there are also provided two limiting protrusions 1434, and on the spray pipe 131, there are provided limiting grooves 1316 corresponding to the two limiting protrusions 1434, so as to form a positioning assembly between the third sealing ring 143 and the spray pipe 131, and at the same time further improve the sealing effect.

[0113] In some embodiments, such as Figure 28 shown, on the side of the third sealing ring 143 facing the second water dividing piece 134, there are provided two third protrusion parts 1433, and the two annular third protrusion parts 1433 respectively extend into the first water dividing hole 1341 and the second water dividing hole 1342 of the second water dividing piece 134, further improving the sealing effect.

[0114] Those skilled in the art will readily conceive of other embodiments of the present disclosure after considering the specification and practicing the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present disclosure, which follow the general principles of the present disclosure and include known common knowledge or conventional technical means in the technical field not disclosed in the present disclosure.
