Therefore, they should not be construed as limiting this invention.
[0044] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "contact," and "communication" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0045] like Figure 1 As shown, the existing waterproof rubber ring 1' of air conditioner motors generally adopts a horn-shaped structure, which has the following problems: when the waterproof rubber ring of the motor is not completely fitted with the fan housing and there is a gap, water will be sucked into the fan housing by the internal centrifugal fan blades and then blown out through the air outlet, affecting the user's use. The direction indicated by the arrow in the figure is the flow path of water intruding into the fan housing.
[0046] Based on this, the following embodiments are proposed.
[0047] Example 1:
[0048] like Figure 2-7 As shown, this embodiment provides a water-blocking component, including: a body portion 6, having a first through hole 101 extending along a first direction; a water-blocking rib, located at one end of the body portion 6 in the first direction, the water-blocking rib being arranged around the outer peripheral wall of the body portion 6 and protruding outward from the outer peripheral wall of the body portion 6, the water-blocking rib being configured to cooperate with the inner groove of the fan housing 7 and being embedded in the inner groove of the fan housing 7; and a mating connection portion 1, located at the other end of the body portion 6 in the first direction, the mating connection portion 1 being configured to extend outward from the outer peripheral wall of the body portion 6, the mating connection portion 1 being configured to be fastened to one end face of the motor 2, such that the rotating shaft 201 of the motor 2 passes through the first through hole 101 and is inserted into the fan cavity formed by the fan housing 7.
[0049] In this embodiment, a water-blocking rib is designed on the mating connection part 1 connected to the motor 2. The water-blocking rib cooperates with the inner groove of the fan housing 7 inside the air conditioner, thereby effectively blocking water from the connection part between the water-blocking component and the fan housing 7 from the circumferential direction, and improving the overall water-blocking performance of the water-blocking component.
[0050] Specifically, the water-blocking component's mating connection part 1 is fastened to one end face of the motor 2; a shaft hole 703 is provided on the fan housing 7, and an inner groove is formed on the fan housing 7 at the shaft hole 703; the water-blocking rib of the water-blocking component is embedded in the inner groove; a fan blade 8 is provided inside the fan cavity of the fan housing 7; the rotating shaft 201 of the motor 2 passes through the first through hole 101 and the shaft hole 703 and is inserted into the fan cavity of the fan housing 7, where it is connected to the fan blade 8 for transmission. The water-blocking rib is embedded in the inner groove of the fan housing 7, resulting in a larger connection area between the water-blocking rib and the fan housing 7, such as... Figure 7 As shown, the upper part of the water-blocking rib is designed in an inverted U-shape to fit into the inner groove of the upper part of the fan housing 7. The upper part of the water-blocking rib acts as a water-blocking rubber ring inserted into the inner groove of the upper part of the fan housing 7. The outermost rib of the inner groove of the upper part of the fan housing 7 serves as the first waterproof rib, which can block most of the rainwater. When a small amount of water splashes up from the bottom gap, the upper part of the water-blocking rib acts as the inner rib, which plays a second waterproof role, effectively preventing the water on the outside from splashing into the inside of the fan housing 7 and being sucked in by the centrifugal fan blades 8 inside, and then blown out through the air outlet, affecting the user's use.
[0051] Furthermore, the lower part of the water-retaining rib mates with the inner groove of the lower part of the fan housing 7, and the lower part of the water-retaining rib is embedded in the inner groove of the lower part of the fan housing 7, so that there is a larger connection area between the water-retaining rib and the fan housing 7, such as... Figure 2 , 7 As shown, the upper part of the water-blocking rib and the inner groove of the upper part of the fan housing 7 are designed in a U-shape. When outdoor rainwater comes in from the bottom, the outermost rib of the inner groove of the lower part of the fan housing 7 first acts as the first layer of waterproofing, and the lower part of the water-blocking rib acts as a water-blocking rubber ring to serve as the second layer of waterproofing. This effectively prevents water from splashing into the fan housing 7 and being sucked in by the internal centrifugal fan blades 8, and then blown out through the air outlet, thus affecting the user's use.
[0052] In this embodiment, the proposed water-blocking component is designed to be configured to cooperate with the inner groove of the fan housing 7 and embedded in the inner groove of the fan housing 7, thereby forming multiple water-blocking barriers and effectively preventing rainwater from passing through. This prevents rainwater from entering the motor 2 and the fan housing 7, thus achieving a more reliable water-blocking effect.
[0053] Optionally, such as Figure 2-7As shown, in one implementation of this embodiment,
[0054] The water-blocking rib includes a first water-blocking rib 3 located at the top, which is constructed as a semi-ring structure. The outer peripheral ring wall of the first water-blocking rib 3 is constructed as a first inclined wall 301. The first inclined wall 301 is inclined in the direction close to the axis of the first through hole 101 in the direction from the first end face 302 to the second end face 303. The first end face 302 is the end face of the first water-blocking rib 3 facing away from the mating connection part 1, and the second end face 303 is the end face of the first water-blocking rib 3 facing the mating connection part 1.
[0055] In this embodiment, preferably, the tilt angle of the first inclined wall 301 relative to the first direction is α, where 10°≤α<70°. The first water-blocking rib 3, as the upper part of the water-blocking rib, is designed in an inverted U-shape to cooperate with the inner groove of the upper part of the fan housing 7. The first water-blocking rib 3, as a water-blocking rubber ring, is inserted into the inner groove of the upper part of the fan housing 7. The outermost rib of the inner groove of the upper part of the fan housing 7, as the first waterproof rib, can block most of the rainwater. When a small amount of water splashes up from the bottom gap, the upper part of the water-blocking rib, as the inner rib, plays a second waterproof role. At the same time, the first inclined wall 301 at the top is designed with an inclination angle between 10° and 70°. In this way, the splashed water will flow back along the first inclined wall 301, preventing water from seeping onto the motor shaft along the outer edge of the first inclined wall 301. At the same time, it can also prevent the water on the outside from splashing into the inside of the fan housing 7 and being sucked in by the internal centrifugal fan blades 8, and then blown out through the air outlet, affecting the user's use.
[0056] Optionally, such as Figure 2-7 As shown, in one implementation of this embodiment,
[0057] The water-blocking rib includes a second water-blocking rib 4 located below, which is constructed as a semi-ring structure. The second water-blocking rib 4 has a third end face 402 and a fourth end face 403. The third end face 402 is away from the mating connection part 1, and the fourth end face 403 faces the mating connection part 1. The third end face 402 is closer to the mating connection part 1 than the fifth end face 404. The third end face 402 and the fifth end face 404 are connected by a second inclined wall 401. The fifth end face 404 is the end face of the body part 6 on the side away from the mating connection part 1.
[0058] In this embodiment, a first water-blocking rib 3 and a second water-blocking rib 4 with different structures are designed on the mating connection part 1 connected to the motor 2. The first water-blocking rib 3 and the second water-blocking rib 4 are respectively connected to the upper part and the lower part of the fan housing 7 in the air conditioner, thereby achieving effective water blocking from two different directions, namely the connection part between the water-blocking component and the fan housing 7, and improving the overall water blocking performance of the water-blocking component.
[0059] In one embodiment, the fan housing 7 includes a first half-housing 701 and a second half-housing 702. The first half-housing 701 and the second half-housing 702 together constitute a fan housing 7 with a shaft hole 703. A first inner groove 704 is formed in the first half-housing 701 near the shaft hole 703, and a second inner groove 705 is formed in the second half-housing 702 near the shaft hole 703. A portion of the water-blocking rib is embedded in the first inner groove 704, and another portion is embedded in the second inner groove 705.
[0060] Specifically, the first water-blocking rib 3 is embedded in and connected to the first inner groove 704, and the first water-blocking rib 3 is connected to the mating connection part 1, and is constructed as a semi-ring structure. The semi-ring structure fits the shape of the first half-shell 701. The second water-blocking rib 4 is embedded in and connected to the second inner groove 705, and the second water-blocking rib 4 is connected to the mating connection part 1, and is constructed as a semi-ring structure. The semi-ring structure fits the shape of the second half-shell 702.
[0061] Preferably, the outer edge of the third end face 402 is provided with a first chamfer 405, and the outer edge of the fourth end face 403 is provided with a second chamfer 406. For example... Figure 7 As shown, the two chamfers replace the right angle design, which can make the stress borne by the second water-blocking rib 4 evenly distributed along the chamfered slope, greatly reducing the local stress peak and preventing the second water-blocking rib from developing micro-cracks under long-term working conditions, thus causing water-blocking failure.
[0062] The two chamfers guide the water flow smoothly, preventing water from accumulating at the right-angled edges and forming pooled water. Furthermore, replacing right angles with chamfers avoids hard interference between the right-angled edges and the inner wall of the second inner groove 705 during assembly, preventing issues such as jamming or scraping, which could lead to assembly difficulties or even scratches on the inner wall of the second inner groove 705, resulting in water leakage.
[0063] Optionally, such as Figure 2-4 As shown in Figures 7 and 8, in one implementation of this embodiment,
[0064] A drainage groove 407 is provided on the lower part of the inner sidewall of the first through hole 101. The drainage groove 407 is configured to extend from the sidewall of the first through hole 101 toward the fifth end face of the body part 6 and to slope downward.
[0065] In this embodiment, preferably, the inclination angle between the bottom wall of the drainage ditch 407 and the first direction is β, where 10°≤β≤70°. Figure 2 , 7 As shown, the second water-blocking rib 4 and the second half-shell 702 are designed in a U-shape. When outdoor rainwater enters from the bottom, the outermost rib of the second half-shell 702 acts as the first layer of waterproofing, and the second water-blocking rib 4, as a water-blocking rubber ring, acts as the second layer of waterproofing. The drainage groove 407 has a length of more than 15mm and a width of 5-10mm. The inclination angle between the bottom wall of the drainage groove and the first direction is β, 10°≤β≤70°. This allows water located on the inner circumference of the second water-blocking rib 4 to flow to the outside along the drainage groove 407, effectively preventing water from flowing back onto the rotating shaft 201 and invading the motor from the connection point, corroding the motor, and causing motor damage.
[0066] Optionally, such as Figure 3 , 5 As shown in Figures 7 and 8, in one implementation of this embodiment,
[0067] The mating connection part 1 has a connecting groove 102 adapted to the end contour of the motor 2, and the connecting groove 102 is fastened to the end of the motor 2; the connecting groove 102 includes at least two stepped grooves 1021, and the at least two stepped grooves 1021 respectively mate with two connected end faces of the motor.
[0068] In this embodiment, a plurality of first connecting protrusions 202 corresponding to the stepped grooves 1021 are formed at the end of the motor 2. When the connecting grooves 102 are fastened to the end of the motor 2, the first connecting protrusions 202 are connected to the corresponding stepped grooves 1021. By providing a partition ring 103 in the connecting grooves 102, a plurality of stepped grooves 1021 are divided in the connecting grooves 102. The plurality of stepped grooves 1021 are a plurality of annular connecting areas, which are connected to the annular first connecting protrusions 202 formed at the end of the motor 2 to form a plurality of connecting parts. This makes the end of the motor 2 and the mating connecting part 1 have a tighter connection relationship and are not easy to fall off. At the same time, a plurality of stepped waterproof parts are formed at the connection between the two to achieve a sealed connection between the mating connecting part 1 and the motor 2 and prevent water from flowing into the motor 2.
[0069] Optionally, such as Figure 2-5 As shown, in one implementation of this embodiment,
[0070] The outer wall of the connecting groove 102 is formed with a first connecting groove 1022 and a second connecting groove 1023, and the first connecting groove 1022 and the second connecting groove 1023 are different in at least one of the dimensions and shapes.
[0071] In this embodiment, the end of the motor 2 is formed with a plurality of second connecting protrusions corresponding one-to-one with the first connecting protrusion 1022 and the second connecting protrusion 1023 in the water-blocking component. When the connecting groove 102 of the water-blocking component is fastened to the end of the motor 2, the plurality of second connecting protrusions are respectively inserted into the corresponding first connecting protrusion 1022 and the second connecting protrusion 1023. By designing the first connecting protrusion 1022 and the second connecting protrusion 1023 with different sizes, different shapes, or both different sizes and shapes, the mating connection part 1 as a whole has the function of preventing reverse installation, thereby improving the overall assembly efficiency of the water-blocking component. The first connecting protrusion 1022 and the second connecting protrusion 1023 are located on the upper and lower sides of the mating connection part 1, respectively. The width of the first connecting protrusion 1022 and the second connecting protrusion 1023 can be designed to differ by more than 4mm, and the height can differ by more than 2mm, making it easier to distinguish them during production and assembly. The water-blocking component proposed in this embodiment can solve the problems of existing motor water-blocking rings having high assembly requirements for mating parts, low assembly efficiency, and being prone to improper assembly, thus affecting the waterproofing effect.
[0072] Optionally, such as Figure 2 , 7 As shown, in one implementation of this embodiment,
[0073] The main body 6 is constructed as a ring structure, and the ring diameter of the main body 6 gradually increases along the direction from the mating connection part 1 to the water-blocking rib.
[0074] In this embodiment, the main body 6 has a trumpet-shaped structure and serves as a connecting component between the mating connection part 1 and the first water-blocking rib 3 and the second water-blocking rib 4. Preferably, the mating connection part 1, the main body 6, the first water-blocking rib 3, and the second water-blocking rib 4 are integrally formed. The arrangement of the main body 6 ensures that there is a certain distance between the mating connection part 1 and the first water-blocking rib 3 and the second water-blocking rib 4. This distance provides more water-blocking space for the water-blocking component to be assembled between the motor 2 and the fan housing 7. The outermost rib of the first half-shell 701, which serves as the first waterproof rib, is inserted into this water-blocking space. The outermost rib of the second half-shell 702, which serves as the first waterproof rib, is also inserted into this water-blocking space. This allows a multi-layer waterproof structure to be formed on the outside of the fan housing 7, improving the water-blocking performance of the water-blocking component on the fan housing 7.
[0075] Example 2
[0076] like Figure 6 , 7As shown, this embodiment provides an assembly component, including: a water-blocking component as in Embodiment 1; a motor 2, wherein the mating connection part 1 of the water-blocking component is fastened to one end face of the motor 2; a fan, wherein the fan includes a fan housing 7, the fan housing 7 has a shaft hole 703, an inner groove is formed on the fan housing 7 and located at the shaft hole 703, the water-blocking rib of the water-blocking component is embedded in the inner groove, a fan blade 8 is provided in the fan cavity of the fan housing 7, and the rotating shaft 201 of the motor 2 passes through the first through hole 101 and the shaft hole 703 and is inserted into the fan cavity of the fan housing 7 and is connected to the fan blade 8 for transmission.
[0077] In this embodiment, the assembly component includes a water-blocking rib on the mating connection part 1 connected to the motor 2. This rib engages with the inner groove of the fan housing 7 inside the air conditioner, effectively blocking water from the connection between the water-blocking component and the fan housing 7 from the circumferential direction, thus improving the overall water-blocking performance of the water-blocking component. The mating connection part 1 of the water-blocking component is fastened to one end face of the motor 2. The fan housing 7 has a shaft hole 703, and an inner groove is formed on the fan housing 7 at the shaft hole 703. The water-blocking rib of the water-blocking component is embedded in the inner groove. A fan blade 8 is installed inside the fan cavity of the fan housing 7. The rotating shaft 201 of the motor 2 passes through the first through hole 101 and the shaft hole 703 and is inserted into the fan cavity of the fan housing 7, where it is connected to the fan blade 8. The water-blocking rib is embedded in the inner groove of the fan housing 7, resulting in a larger connection area between the water-blocking rib and the fan housing 7. Figure 7 As shown, the upper part of the water-blocking rib is designed in an inverted U-shape to fit into the inner groove of the upper part of the fan housing 7. The upper part of the water-blocking rib acts as a water-blocking rubber ring inserted into the inner groove of the upper part of the fan housing 7. The outermost rib of the inner groove of the upper part of the fan housing 7 serves as the first waterproof rib, which can block most of the rainwater. When a small amount of water splashes up from the bottom gap, the upper part of the water-blocking rib acts as the inner rib, which plays a second waterproof role, effectively preventing the water on the outside from splashing into the inside of the fan housing 7 and being sucked in by the centrifugal fan blades 8 inside, and then blown out through the air outlet, affecting the user's use.
[0078] Furthermore, the lower part of the water-retaining rib mates with the inner groove of the lower part of the fan housing 7, and the lower part of the water-retaining rib is embedded in the inner groove of the lower part of the fan housing 7, so that there is a larger connection area between the water-retaining rib and the fan housing 7, such as... Figure 2 , 7As shown, the upper part of the water-blocking rib and the inner groove of the upper part of the fan housing 7 are designed in a U-shape. When outdoor rainwater comes in from the bottom, the outermost rib of the inner groove of the lower part of the fan housing 7 first acts as the first layer of waterproofing, and the lower part of the water-blocking rib acts as a water-blocking rubber ring to serve as the second layer of waterproofing. This effectively prevents water from splashing into the fan housing 7 and being sucked in by the internal centrifugal fan blades 8, and then blown out through the air outlet, thus affecting the user's use.
[0079] In this embodiment, the proposed assembly component, by having water-blocking ribs in the water-blocking component configured to cooperate with the inner groove of the fan housing 7 and embedded in the inner groove of the fan housing 7, can form multiple water-blocking barriers, effectively preventing rainwater from passing through and preventing rainwater from entering the motor 2 and the fan housing 7, thereby achieving a more reliable water-blocking effect.
[0080] Optionally, such as Figure 6 , 7 As shown, in one implementation of this embodiment,
[0081] The fan housing 7 includes a first half-housing 701 and a second half-housing 702. The first half-housing 701 and the second half-housing 702 together constitute a fan housing 7 with a shaft hole 703. The first half-housing 701 has a first inner groove 704 formed near the shaft hole 703, and the second half-housing 702 has a second inner groove 705 formed near the shaft hole 703. A portion of the water-blocking rib is embedded in the first inner groove 704, and another portion is embedded in the second inner groove 705.
[0082] In this embodiment, the first water-blocking rib 3 is embedded in and connected to the first inner groove 704. The first water-blocking rib 3 is connected to the mating connection part 1 and is constructed as a semi-ring structure, which fits the shape of the first half-shell 701. The second water-blocking rib 4 is embedded in and connected to the second inner groove 705. The second water-blocking rib 4 is connected to the mating connection part 1 and is constructed as a semi-ring structure, which fits the shape of the second half-shell 702. The mating connection part 1, where the water-blocking component connects to the motor 2, is designed with different structures for the first water-blocking rib 3 and the second water-blocking rib 4. The first water-blocking rib 3 and the second water-blocking rib 4 are respectively connected to the first half-shell 701 and the second half-shell 702 in the fan housing 7 inside the air conditioner, thereby achieving effective water blocking from two different directions (top and bottom) at the connection between the water-blocking component and the fan housing 7, improving the overall water-blocking performance of the water-blocking component.
[0083] Optionally, such as Figure 8 As shown, in one implementation of this embodiment,
[0084] When the fan housing 7 is assembled inside the air conditioner, the first half-housing 701 is located on the upper side of the second half-housing 702; the lower end of the second inner groove 705 is provided with a drain hole 706 facing outward.
[0085] In this embodiment, the second water-blocking rib 4 and the second half-shell 702 are designed in a U-shaped fit. When rainwater from the outside comes in from the bottom, the outermost rib of the second half-shell 702 first acts as the first layer of waterproofing, and the second water-blocking rib 4, as a water-blocking rubber ring, acts as the second layer of waterproofing. The U-groove formed by the second water-blocking rib 4 and the second half-shell 702 catches the water splashing in from the outside. The drainage hole 706 allows the water at this location to be discharged outwards, preventing water from accumulating at the bottom of the U-groove. The drainage groove 407 can guide the water located on the inner circumference of the second water-blocking rib 4 to the outside and discharge it outwards through the drainage hole 706, effectively preventing water from flowing back onto the rotating shaft 201 and invading the motor from the connection point, corroding the motor and causing damage.
[0086] Optionally, such as Figure 6 , 7 As shown, in one implementation of this embodiment,
[0087] The end of the motor 2 is formed with a plurality of second connecting protrusions that correspond one-to-one with the first connecting protrusion 1022 and the second connecting protrusion 1023 in the water baffle. When the connecting groove 102 of the water baffle is fastened to the end of the motor 2, the plurality of second connecting protrusions are respectively inserted into the corresponding first connecting protrusion 1022 and second connecting protrusion 1023.
[0088] In this embodiment, multiple second connecting protrusions are formed at the end of the motor 2, corresponding one-to-one with the first connecting protrusion 1022 and the second connecting protrusion 1023. When the connecting groove 102 is fastened to the end of the motor 2, the multiple second connecting protrusions are respectively connected to the corresponding first connecting protrusion 1022 and second connecting protrusion 1023. By designing the first connecting protrusion 1022 and the second connecting protrusion 1023 with different sizes, shapes, or both sizes and shapes, the mating connection part 1 as a whole has the function of preventing reverse installation, thereby improving the overall assembly efficiency of the assembly component. The first connecting protrusion 1022 and the second connecting protrusion 1023 are located on the upper and lower sides of the mating connection part 1, respectively. The width of the first connecting protrusion 1022 and the second connecting protrusion 1023 can be designed to differ by more than 4mm, and the height can differ by more than 2mm, making it easier to distinguish them during production and assembly.
[0089] By forming multiple first connecting protrusions 202 corresponding to the stepped grooves 1021 at the end of the motor 2, when the connecting grooves 102 are fastened to the end of the motor 2, the first connecting protrusions 202 are connected to the stepped grooves 1021. A partition ring 103 is provided in the connecting grooves 102 to divide the connecting grooves 102 into multiple stepped grooves 1021. The multiple stepped grooves 1021 are multiple annular connecting areas, which are connected to the annular first connecting protrusions 202 formed at the end of the motor 2 to form multiple connecting parts. This makes the end of the motor 2 and the mating connecting part 1 have a tighter connection relationship and are not easy to fall off. At the same time, multiple stepped waterproof parts are formed at the connection between the two to achieve a sealed connection between the mating connecting part 1 and the motor 2, preventing water from flowing into the motor 2.
[0090] Example 3
[0091] like Figure 2-8 As shown, this embodiment provides an air conditioner, including: the assembly component in embodiment two.
[0092] In this embodiment, the air conditioner includes the assembly components from Embodiment 2, and therefore has all the beneficial effects of the assembly components, which will not be described in detail here.
[0093] In summary, the ingenious design of the water-blocking component lies in:
[0094] In the water-blocking component, the mating connection part connected to the motor is designed with a first water-blocking rib and a second water-blocking rib. The first water-blocking rib and the second water-blocking rib are respectively connected to the upper and lower parts of the fan housing inside the air conditioner, thereby achieving effective water blocking from different circumferential directions at the connection part between the water-blocking component and the fan housing. The water-blocking ribs in the water-blocking component, together with the fan housing, can form multiple water-blocking barriers, effectively preventing rainwater from passing through and preventing rainwater from entering the motor and fan housing, thus achieving a more reliable water-blocking effect and improving the overall water-blocking performance of the water-blocking component.
[0095] By embedding the first water-blocking rib into the first inner groove and connecting it to the connecting part, a semi-ring structure is constructed. The semi-ring structure fits the shape of the first half-shell, and the two have a larger connection area. The outer peripheral ring wall of the first water-blocking rib is constructed as the first inclined wall. The first water-blocking rib and the first half-shell are designed to fit together in an inverted U-shape. The first water-blocking rib, as a water-blocking rubber ring, is inserted into the first inner groove in the first half-shell. The outermost rib of the first half-shell, as the first waterproof rib, can block most of the rainwater. When a small amount of water splashes up from the bottom gap, the first water-blocking rib, as the inner rib, plays a second waterproof role. The splashed water will flow back along the first inclined wall, preventing water from seeping onto the motor shaft along the outer edge of the first inclined wall. At the same time, it can also prevent water from splashing into the fan housing to the maximum extent, and then being sucked in by the internal centrifugal fan blades and blown out through the air outlet, affecting the user's use.
[0096] Furthermore, the second water-blocking rib is embedded in the second inner groove and connected to the connecting part, forming a semi-ring structure. The second water-blocking rib and the second half-shell are designed to fit in a U-shape. When rainwater from the outside comes in from the bottom, the outermost rib of the second half-shell first acts as the first layer of waterproofing, and the second water-blocking rib, as a water-blocking rubber ring, acts as the second layer of waterproofing. The drainage groove can guide the water located on the inner circumference of the second water-blocking rib to the outside along the water-guiding groove structure, effectively preventing water from flowing back onto the shaft and invading the motor from the connection point, corroding the motor and causing damage.
