[0063] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0064] Figure 1 A pool cleaner 100 is shown.
[0065] refer to Figures 1 to 3 The pool cleaner 100 includes a main unit 200 and replaceable cleaning components 500 (e.g., pool bottom cleaning component 510 or...). Figure 4 The water surface cleaning assembly 520 shown is included. The main unit 200 includes a housing 201, a water spray assembly 220, a water pump assembly 300, and a filter 400. The housing 201 is hollow to form an inner cavity 202. The water spray assembly 220 is mounted on the housing 201 and includes a spray nozzle 203. The inner cavity 202 of the housing 201 is in fluid communication with the spray nozzle 203 of the water spray assembly 220. The water pump assembly 300 is mounted within the inner cavity 202 of the housing 201 and drives water to be sprayed from the spray nozzle 203. The sprayed water exerts a reaction force on the pool cleaner 100, thereby propelling the pool cleaner 100 to move within the pool. For example, the spray nozzle 203 is positioned rearward (e.g.,...). Figure 6 Water jets out in the X direction (as shown), and the pool cleaner 100 moves forward (e.g., in the X direction). Figure 6 (Movement in the Y direction as shown).
[0066] like Figure 3 As shown, in this embodiment, the water pump assembly 300 includes a motor 301, an impeller 302, and a battery 303. The battery 303 is electrically connected to the motor 301, supplying power to the motor 301. The motor 301 drives the impeller 302 to rotate, causing water to be sprayed from the nozzle 203, providing power for the movement of the pool cleaner 100 within the pool. This embodiment uses the battery 303 as the power source to drive the impeller 302 through the motor 301, thus eliminating the need for external water pipes or cables to power the pool cleaner 100, making the pool cleaner 100 easy to operate.
[0067] like Figure 2 and Figure 3 As shown, the housing 201 of the main unit 200 includes a main unit interface 204, and the filter element 400 includes a frame 410 and a filter screen 413. The frame 410 has a plurality of filter ports 411, and the filter screen 413 covers the filter ports 411. The outer periphery of the frame 410 of the filter element 400 is connected to the inner periphery of the main unit interface 204 and is recessed into the inner cavity 202 of the main unit 200. When water flows from the cleaning component through the filter ports 411 to the inner cavity 202, the filter screen 413 filters the water entering the inner cavity 202.
[0068] like Figure 1 and Figure 4 As shown, the replaceable cleaning components 500 include a bottom cleaning component 510 and a surface cleaning component 520, and the main unit 200 can selectively connect to both the bottom cleaning component 510 and the surface cleaning component 520. Specifically, the bottom cleaning component 510 includes a bottom interface 514 and a bottom suction port 511, and the bottom interface 514 matches the main unit interface 204. When the main unit 200 is connected to the bottom cleaning component 510, the bottom interface 514 and the main unit interface 204 are mated, and the bottom suction port 511 communicates with the inner cavity 202. That is, water and dirt (such as garbage, leaves, etc.) enter the inner cavity 202 through the suction port 511 at the bottom of the pool and are filtered by the filter element 400 in the inner cavity 202, leaving the dirt in the pool cleaner 100. The water flowing through the filter element 400 is sprayed out from the spray nozzle 203 under the rotation of the impeller 302, achieving cleaning while providing forward power for the pool cleaner 100.
[0069] refer to Figures 4 to 6 The aforementioned water surface cleaning component 520 includes a water surface interface 529 and at least one water surface suction port 521, with the water surface interface 529 mating with the host interface 204. When the host 200 is connected to the water surface cleaning component 520, the water surface interface 529 and the host interface 204 are connected, and the water surface suction port 521 communicates with the inner cavity 202. That is, water and dirt (such as garbage, leaves, etc.) entering through the water surface suction port 521 enter the inner cavity 202 and are filtered by the filter element 400 inside the inner cavity 202, leaving the dirt inside the pool cleaner 100. The water flowing through the filter element 400 is sprayed out from the spray nozzle 203 under the rotation of the impeller 302, achieving cleaning while providing forward propulsion for the pool cleaner 100.
[0070] In other words, the pool cleaner 100 has two working configurations: a pool bottom cleaning configuration and a... Figure 1 (as shown) and surface cleaning configuration ( Figure 4As shown, the main unit 200 is connected to the pool bottom cleaning component 510, enabling pool bottom cleaning (i.e., pool bottom cleaning configuration). The main unit 200 is also connected to the water surface cleaning component 520, enabling water surface cleaning (i.e., water surface cleaning configuration).
[0071] Using the above technical solution, refer to Figures 1 to 3 When the pool bottom cleaning component 510 is used in conjunction with the main unit 200, the pool cleaner 100 will submerge in the pool bottom to clean the dirt deposited there. Driven by the motor 301, the impeller 302 rotates, creating suction between the pool bottom suction port 511 and the pool bottom. Water and dirt (such as garbage, leaves, etc.) from the pool bottom enter the inner cavity 202 through the suction port 511 and are filtered by the filter element 400 within the inner cavity 202, leaving the dirt inside the pool cleaner 100. The water flowing through the filter element 400 is then sprayed out from the spray nozzle 203 by the rotation of the impeller 302, thus cleaning the pool bottom while providing the power for the pool cleaner 100 to move.
[0072] refer to Figures 4 to 6 When the surface cleaning component 520 is used in conjunction with the main unit 200, the pool cleaner 100 floats on the water surface to clean up floating debris. Water and debris (such as garbage, leaves, etc.) entering through the surface suction port 521 enter the inner cavity 202 and are filtered by the filter element 400 inside the inner cavity 202, leaving the debris inside the pool cleaner 100. The water flowing through the filter element 400 is sprayed out from the spray nozzle 203 by the rotation of the impeller 302, achieving surface cleaning while providing forward propulsion for the pool cleaner 100.
[0073] That is, by setting up replaceable pool bottom cleaning component 510 and water surface cleaning component 520, this embodiment allows them to be detachably connected to the main unit 200 for different cleaning needs of the pool (such as pool bottom cleaning and water surface cleaning). When pool bottom cleaning is needed, the main unit 200 is connected to the pool bottom cleaning component 510, and when water surface cleaning is needed, the main unit 200 is connected to the water surface cleaning component 520. Thus, the pool cleaner 100 of this application has both pool bottom cleaning and water surface cleaning functions at the same time, eliminating the need to equip separate cleaning products for the pool bottom or water surface, and eliminating the need for manual cleaning, thereby saving product costs and labor costs.
[0074] Additionally, refer to Figure 1 , Figure 3 , Figure 7 and Figure 8The water spray assembly 220 is rotatably mounted on the housing 201 of the main unit 200. The water spray assembly 220 has a water nozzle 203 and a positioning protrusion 221 extending outward from the water nozzle 203. For example, when the water spray assembly 220 is not prevented from rotating, the rotational force of the impeller 302 will drive the water spray assembly 220 to rotate. When the water spray assembly 220 rotates circumferentially in the horizontal direction relative to the housing 201, the orientation of the water nozzle 203 will correspondingly change relative to the housing 201, thereby achieving the purpose of adjusting the direction of the water nozzle 203 and further changing the movement direction of the pool cleaner 100.
[0075] The host 200 in this embodiment further includes a reversing assembly 210, which includes a reversing member 230 and a handle 232. The reversing member 230 includes a plurality of stops 231 spaced apart along the rotation path of the water spray assembly 220. The plurality of stops 231 are adapted to reciprocate to enter and leave the rotation path of the positioning protrusion 221, so as to correspondingly prevent the water spray assembly 220 from rotating and allow the water spray assembly 220 to pass through, thereby changing the orientation of the water nozzle 203 relative to the housing 201.
[0076] When using the reversing assembly 210 of this application, by moving one stop 231 into the rotation path of the positioning protrusion 221, the water spray assembly 220 can be stopped at a certain angle. Correspondingly, the water nozzle 203 faces a certain angle relative to the housing 201, thus allowing the pool cleaner 100 to move in a specific direction. When the stop 231 is moved away from the rotation path of the positioning protrusion 221 and another stop 231 is moved into the rotation path of the positioning protrusion 221, the water spray assembly 220 will rotate a certain angle range and stop at another angle. Consequently, the water nozzle 203 also switches to face another angle relative to the housing 201, thus allowing the pool cleaner 100 to move in another direction.
[0077] Therefore, by replacing the stop 231 in the rotation path of the positioning protrusion 221, the movement direction of the pool cleaner 100 can be accurately changed, avoiding the phenomenon of the pool cleaner 100 spinning in place and improving the cleaning efficiency of the pool cleaner 100.
[0078] The handle 232 is connected to multiple stops 231. During use of the pool cleaner 100, as the pool cleaner 100 stops moving (e.g., by touching a pool wall or obstacle), the handle 232 stands upright near a neutral position due to its own buoyancy. The water spray assembly 220 rotates 180 degrees due to the rotational force of the impeller 302, is stopped by the stops 231, reaches a stable state, and completes the reversal, continuing to operate in the opposite direction. That is, the pool cleaner 100 of this embodiment achieves automatic reversal without manual control or processor control, greatly facilitating user operation, significantly improving pool cleaning efficiency, and reducing the cost of the pool cleaner 100.
[0079] The following section will first describe in detail the pool bottom cleaning configuration of the pool cleaner 100 with reference to the accompanying drawings.
[0080] like Figures 1 to 3 As shown, in the pool bottom cleaning configuration, the pool cleaner 100 is submerged in the pool. The main unit 200 of the pool cleaner 100 is located above the pool bottom cleaning component 510. The pool bottom cleaning component 510 is equipped with four wheels 512. The wheels 512 are in contact with the pool bottom and can drive the pool cleaner 100 to move on the pool bottom to clean various parts of the pool bottom.
[0081] Specifically, the pool bottom cleaning component 510 includes an internal chamber 513, which communicates with the inner cavity 202 of the housing 201 and with the pool bottom suction port 511 provided in the pool bottom cleaning component 510. The bottom suction port 511 and the bottom docking port 514 are arranged opposite to each other on the bottom cleaning component 510. The bottom suction port 511 faces the bottom of the pool. During the movement of the pool cleaner 100, the battery 303 supplies power to the motor 301. The motor 301 drives the impeller 302 to rotate, forming a suction force between the bottom suction port 511 and the bottom of the pool. This suction force draws dirt from the bottom of the pool into the internal chamber 513 along with the water. The dirt flows with the water into the inner cavity 202 of the main unit 200 and passes through the filter element 400. The filter element 400 intercepts the dirt. The filtered water continues to flow to the spray nozzle 203 and is sprayed out from the spray nozzle 203 under the drive of the rotation of the impeller 302, returning the water to the pool. This achieves the cleaning of the bottom of the pool while providing power for the movement of the pool cleaner 100.
[0082] In this embodiment, the main unit 200 has protrusions 205 on both sides, and the pool bottom cleaning component 510 has a slot 501 that mates with the protrusions 205. That is, the protrusions 205 are embedded in the slots 501, thereby detachably connecting the pool bottom cleaning component 510 and the main unit 200, so that different cleaning components 500 can be replaced for the main unit 200. However, those skilled in the art will understand that in other embodiments, the main unit 200 and the cleaning component 500 can also be connected in other ways, such as by screws.
[0083] The following section will describe in detail the water surface cleaning configuration of the pool cleaner 100 with reference to the accompanying drawings.
[0084] refer to Figure 1 and Figure 4 Compared to the bottom-cleaning configuration, the surface-cleaning pool cleaner 100 differs in two ways: firstly, the bottom-cleaning component 510 is replaced with a surface-cleaning component 520; secondly, the entire pool cleaner 100 is rotated 180°. That is, the pool cleaner 100 floats on the water surface, with the main unit 200 located below the surface-cleaning component 520, which contacts the water surface to clean it.
[0085] Specifically, refer to Figures 3 to 6 The water surface cleaning component 520 includes a water surface chamber 522 communicating with the inner cavity 202 of the housing 201. A water surface inlet 521 communicating with the water surface chamber 522 is provided on the side of the water surface cleaning component 520, with its upper edge 523 above the water surface and its lower edge 524 below the water surface. That is, the water level line S of the pool is located between the upper edge 523 and the lower edge 524 of the water surface inlet 521. Thus, dirt floating on the water surface can enter the water surface chamber 522 along with the water from the water surface inlet 521, and then flow into the inner cavity 202 of the housing 201. The dirt entering the inner cavity 202 is intercepted at the filter element 400. The filtered water continues to flow to the spray nozzle 203 and is sprayed out from the spray nozzle 203 under the drive of the rotating impeller 302, returning the water to the pool. This achieves water surface cleaning while providing power for the movement of the pool cleaner 100.
[0086] In some possible implementations, to provide buoyancy to the pool cleaner 100, a buoyancy structure (not shown in the figure) is provided in the water surface chamber 522 of the water surface cleaning assembly 520. This buoyancy structure can be an air cavity or a foam block. In this embodiment, the water surface cleaning assembly 520 is rectangular, and its four corners within the water surface chamber 522 are provided with enclosed chambers filled with air, i.e., air cavities, which provide buoyancy to the water surface cleaning assembly 520 while ensuring balance. Those skilled in the art will understand that the buoyancy structure is not limited to the two types described above. In other embodiments, other buoyancy structures, such as buoyancy wings, can also provide buoyancy to the pool cleaner 100.
[0087] refer to Figures 4 to 6The aforementioned water surface intake 521 includes a first water surface intake 525 and a second water surface intake 526 disposed opposite to each other. Both the first water surface intake 525 and the second water surface intake 526 are connected to the water surface chamber 522 and are in fluid communication with the water surface interface 529, respectively. Exemplarily, the first water surface intake 525 and the second water surface intake 526 are located on the sides of the pool cleaner 100, where the water surface cleaning assembly 520 is located, in the direction of movement.
[0088] In the first direction of movement Y (which can also be understood as the forward direction) of the pool cleaner 100, the first water surface inlet 525 is located in front of the second water surface inlet 526, with the first water surface inlet 525 open and the second water surface inlet 526 closed. That is, when the pool cleaner 100 moves along the first direction of movement Y, the first water surface inlet 525 is located at the front end of the pool cleaner 100 in the first direction of movement Y, facing the water flow directly. The second water surface inlet 526 is located at the rear end of the pool cleaner 100 in the first direction of movement Y, facing away from the water flow.
[0089] The first water surface inlet 525, facing the water flow, is opened to allow dirt on the water surface to enter the water surface chamber 522 along with the water flow. The water then flows into the inner cavity 202 of the housing 201, where it is filtered by the filter element 400. The filtered water continues to flow to the spray nozzle 203 and, driven by the rotation of the impeller 302, is sprayed out of the nozzle, returning the water to the pool. The water flow direction inside the pool cleaner 100 is as follows: Figure 6 As indicated by the middle arrow Z. The second water surface inlet 526, which faces away from the water flow, is closed to prevent dirt entering the water surface chamber 522 from the first water surface inlet 525 from flowing directly out of the second water surface inlet 526, thus preventing filtration.
[0090] refer to Figure 9 In the second direction of movement X (which can also be understood as the backward direction) of the pool cleaner 100, the second water surface inlet 526 is located in front of the first water surface inlet 525, the second water surface inlet 526 is open, and the first water surface inlet 525 is closed; the first direction of movement Y and the second direction of movement X are opposite directions.
[0091] The first direction of movement Y mentioned in this embodiment can also be described as the direction from the second water surface inlet 526 to the first water surface inlet 525. Correspondingly, the second direction of movement X is the direction from the first water surface inlet 525 to the second water surface inlet 526. It can be understood that the orientation of the open nozzles in the first water surface inlet 525 and the second water surface inlet 526 is opposite to the orientation of the spray nozzle 203.
[0092] That is, when the pool cleaner 100 moves along the second direction of motion X, the second water surface inlet 526 is located at the front end of the pool cleaner 100 in the second direction of motion X, facing the water flow directly. The first water surface inlet 525 is located at the rear end of the pool cleaner 100 in the second direction of motion X, facing away from the water flow.
[0093] The second water surface inlet 526, facing the water flow, is opened to allow dirt on the water surface to enter the water surface chamber 522 along with the water flow, and then flow into the inner chamber 202, where filtration is achieved. The water flow direction inside the pool cleaner 100 is as follows: Figure 9 As indicated by the middle arrow U. The first water surface inlet 525, which faces away from the water flow, is closed to prevent dirt entering the water surface chamber 522 from the second water surface inlet 526 from flowing directly out of the first water surface inlet 525, thus preventing filtration.
[0094] like Figure 6 and Figure 9 As shown, the water surface cleaning assembly 520 also includes a first water-blocking plate 530 and a second water-blocking plate 540.
[0095] The first water-blocking plate 530 is rotatably installed in the water surface chamber 522 of the water surface cleaning component 520 and is located at the position of the first water surface suction port 525 to close the first water surface suction port 525.
[0096] The first water-blocking plate 530 includes a first end 531 and a second end 534. The second end 534 of the first water-blocking plate is rotatable relative to the first end 531 of the first water-blocking plate toward the interior of the water surface cleaning assembly 520, thereby opening the first water surface suction port 525. Exemplarily, when the pool cleaner 100 moves along a first direction of movement Y, the first water-blocking plate 530 opens the first water surface suction port 525; when the pool cleaner 100 moves along a second direction of movement X, the first water-blocking plate 530 closes the first water surface suction port 525. Exemplarily, the first water-blocking plate 530 is plate-shaped.
[0097] For example, refer to Figures 9 to 11 The first end 531 of the first water-blocking plate is provided with a first rotating shaft 532, which is inserted into a first rotating groove 533 provided on the cavity wall of the water surface chamber 522, thereby forming a rotating connection between the first water-blocking plate 530 and the cavity wall of the water surface chamber 522.
[0098] For example, such as Figure 9 and Figure 10As shown, the area of the first water-blocking plate 530 is larger than the area of the first water surface inlet 525, thereby facilitating the formation of sufficient shielding of the first water surface inlet 525 by the first water-blocking plate 530, so as to prevent dirt entering through the second water surface inlet 526 from leaking through the gap between the first water surface inlet 525 and the first water-blocking plate 530 when the pool cleaner 100 moves along the second direction of movement X.
[0099] In this embodiment, a first buoyancy device 535 is fixedly installed on the first water-blocking plate 530. When the first water-blocking plate 530 is in the position of closing the first water surface inlet 525, the first end 531 of the first water-blocking plate is located between the second end 534 of the first water-blocking plate and the housing 201 of the pool cleaner 100 (the working process of the first water-blocking plate 530 will be described in detail below). For example, the first buoyancy device 535 is a foam box, which provides buoyancy to the first water-blocking plate 530, that is, provides power for the first water-blocking plate 530 to close the first water surface inlet 525.
[0100] refer to Figure 9 , Figure 12 and Figure 13 In other embodiments, the first water-blocking plate 530 provides power to close the first water surface intake 525 via a first torsion spring 536. Specifically, the first torsion spring 536 is disposed at the first end 531 of the first water-blocking plate, and provides the torque to close the first water surface intake 525. Exemplarily, the first torsion spring 536 includes a first end 537 and a second end 538, wherein the first end 537 is fixed to the cavity wall of the water surface chamber 522, and the second end 538 is connected to the first water-blocking plate 530. Thus, without the application of an external force (such as the force of water), the first water-blocking plate 530 always blocks the first water surface intake 525 under the action of the first torsion spring 536.
[0101] by Figure 6 and Figure 9 Taking the first water-blocking plate 530 as an example, the working process is described. Figure 9 When the pool cleaner 100 is stationary, the first water-blocking plate 530 is in an upright position, closing the first water surface inlet 425. At this time, the first end 531 of the first water-blocking plate is located between the second end 534 of the first water-blocking plate and the housing 201 of the pool cleaner 100. When the pool cleaner 100 moves along the first direction of motion Y, the first water surface inlet 525 faces the water flow directly. The force of the water flow causes the first water-blocking plate 530 to rotate downward from its original upright position, opening the first water surface inlet 525 and allowing water to enter. Figure 6At this point, the first end 531 and the second end 534 of the first water-blocking plate are roughly arranged horizontally, so the first end 531 of the first water-blocking plate is no longer between the second end 534 of the first water-blocking plate and the housing 201 of the pool cleaner 100. When the pool cleaner 100 hits the pool wall or an obstacle and changes direction under the action of the reversing component 210, switching from the first direction of movement Y to the second direction of movement X (e.g., from forward to backward), the first water-blocking plate 530 rotates upward under the action of the buoyancy of the water or the first torsion spring 536 to restore it to an upright state, thereby shielding the first water surface inlet 525, that is, closing the first water surface inlet 525. At this time, the first end 531 of the first water-blocking plate returns to the space between the second end 534 of the first water-blocking plate and the housing 201 of the pool cleaner 100.
[0102] Correspondingly, such as Figure 6 and Figure 9 As shown, the second water-blocking plate 540 is rotatably installed in the water surface chamber 522 of the water surface cleaning assembly 520 and is positioned at the second water surface inlet 526 to close the second water surface inlet 526.
[0103] The second water-blocking plate 540 includes a first end 541 and a second end 544. The second end 544 of the second water-blocking plate is rotatable relative to the first end 541 towards the interior of the water surface cleaning assembly 520, thereby opening the second water surface suction port 526. Exemplarily, when the pool cleaner 100 moves along the second direction of movement X, the second water-blocking plate 540 opens the second water surface suction port 526; when the pool cleaner 100 moves along the first direction of movement Y, the second water-blocking plate 540 closes the second water surface suction port 526. Exemplarily, as... Figure 9 , Figure 10 and Figure 14 As shown, the first end 541 of the second water-blocking plate is provided with a second rotating shaft 542, which is inserted into a second rotating groove 543 provided on the cavity wall of the water surface chamber 522, thereby forming a rotating connection between the second water-blocking plate 540 and the cavity wall of the water surface chamber 522.
[0104] For example, the area of the second water-blocking plate 540 is larger than the area of the second water surface inlet 526, thereby facilitating the formation of sufficient shielding of the second water surface inlet 526 by the second water-blocking plate 540, so as to prevent dirt entering through the first water surface inlet 525 from leaking through the gap between the second water surface inlet 526 and the second water-blocking plate 540 when the pool cleaner 100 moves along the first direction of movement Y.
[0105] In this embodiment, a second buoyancy device 545 is fixedly installed on the second water-blocking plate 540. When the second water-blocking plate 540 is in the position of closing the second water surface inlet 526, the first end 541 of the second water-blocking plate is located between the second end 544 of the second water-blocking plate and the housing 201 of the pool cleaner 100. The second buoyancy device 545 provides buoyancy to the second water-blocking plate 540, which is the power for the second water-blocking plate 540 to close the second water surface inlet 526. For example, the second buoyancy device 545 is a foam box.
[0106] In other embodiments, such as Figure 15 and Figure 16 As shown, the second water-blocking plate 540 provides power to close the second water surface suction port 526 via a second torsion spring 546. Specifically, the second torsion spring 546 is disposed at the first end 541 of the second water-blocking plate, and the second torsion spring 546 provides the torque to close the second water surface suction port 526.
[0107] For example, the second torsion spring 546 includes a third end 547 and a fourth end 548, wherein the third end 547 is fixed to the cavity wall of the water surface chamber 522, and the fourth end 548 is connected to the second water blocking plate 540. In the absence of an external force (such as the force of water), the second water blocking plate 540 always blocks the second water surface intake port 526 under the action of the second torsion spring 546.
[0108] refer to Figure 3 , Figure 6 and Figure 9 When the pool cleaner 100 is stationary, the second water-blocking plate 540 is in an upright position, closing the second water surface inlet 526. At this time, the first end 541 of the second water-blocking plate is located between the second end 544 of the second water-blocking plate and the housing 201 of the pool cleaner 100. When the pool cleaner 100 moves along the second direction of motion X, the second water surface inlet 526 faces the water flow directly. The force of the water flow causes the second water-blocking plate 540 to rotate downward from its original upright position, that is, the second water-blocking plate 540 opens the second water surface inlet 526, allowing water to enter. Figure 9At this point, the first end 541 and the second end 544 of the second water-blocking plate are roughly aligned horizontally, so the first end 541 of the second water-blocking plate is no longer between the second end 544 of the second water-blocking plate and the housing 201 of the pool cleaner 100. When the pool cleaner 100 hits the pool wall or an obstacle and is reversing under the action of the reversing component 210, switching from the second direction of movement X to the first direction of movement Y, the second water-blocking plate 540 rotates upward under the action of buoyancy or the second torsion spring 546 to restore it to an upright state, thereby shielding the second water surface inlet 526, i.e., closing the second water surface inlet 526. At this time, the first end 541 of the second water-blocking plate returns to the space between the second end 544 of the second water-blocking plate and the housing 201 of the pool cleaner 100.
[0109] In summary, when the pool cleaner 100 moves along the first direction of motion Y, the first water-blocking plate 530 opens the first water surface suction port 525, and the second water-blocking plate 540 closes the second water surface suction port 526. When the pool cleaner 100 moves along the second direction of motion X, the second water-blocking plate 540 opens the second water surface suction port 526, and the first water-blocking plate 530 closes the first water surface suction port 525.
[0110] like Figure 9 and Figure 15 As shown, the water surface cleaning assembly 520 also includes a screen 550, which is fixed between the first water surface inlet 525 and the second water surface inlet 526. The screen 550 is used to prevent dirt entering through the first water surface inlet 525 from flowing into the second water surface inlet 526, and to prevent dirt entering through the second water surface inlet 526 from flowing into the first water surface inlet 525. Exemplarily, the upper end of the screen 550 is connected to the top wall of the water surface chamber 522, and the lower end is connected to the filter element 400, thereby dividing the water surface chamber 522 into a first portion 527 and a second portion 528.
[0111] For example, when the pool cleaner 100 moves along the first direction of movement Y, dirt on the water surface enters the water surface chamber 522 along with the water from the first water surface inlet 525. While it flows towards the filter element 400, some dirt and water may also flow towards the second water surface inlet 526. The screen 550 located between the first water surface inlet 525 and the second water surface inlet 526 can filter the dirt and water flowing towards the second water surface inlet 526, intercepting the dirt in the first part 527 of the water surface chamber 522 and preventing it from entering the second part 528, that is, preventing it from approaching the second water surface inlet 526. This prevents the second water surface inlet 526 from opening directly when the pool cleaner 100 changes direction, causing the dirt at the second water surface inlet 526 to flow back into the pool and affect the cleaning effect on the pool.
[0112] Correspondingly, when the pool cleaner 100 moves along the second direction of motion X, dirt on the water surface enters the water surface chamber 522 along with the water from the second water surface inlet 526. While it flows towards the filter element 400, some dirt and water may also flow towards the first water surface inlet 525. The screen 550 located between the first water surface inlet 525 and the second water surface inlet 526 can filter the dirt and water flowing towards the first water surface inlet 525, intercepting the dirt in the second part 528 of the water surface chamber 522, preventing it from entering the first part 527, that is, near the first water surface inlet 525. This prevents the first water surface inlet 525 from opening directly when the pool cleaner 100 changes direction, causing the dirt at the first water surface inlet 525 to flow back into the pool, affecting the cleaning effect on the pool.
[0113] like Figure 5 , Figure 9 and Figure 15 As shown, the water surface cleaning component 520 defines at least one water flow channel 561, which is arranged through the water flow channel 561 parallel to the movement direction of the pool cleaner 100, wherein the host interface 204 is connected to the water surface interface 529.
[0114] In this embodiment, two water flow channels 561 are provided. The two water flow channels 561 are respectively defined by two water guide tubes 560 located on both sides of the water surface cleaning component 520. Each water guide tube 560 extends along the movement direction of the pool cleaner 100 and runs through the front and back.
[0115] Because the water jet from nozzle 203 is propelled by the rotation of impeller 302, and because impeller 302 rotates at high speed and the housing 201 of main unit 200 itself has a curvature, the water jet has a certain angle when it is sprayed out. Without any intervention, the trajectory of the pool cleaner 100 will be arc-shaped. If the curvature is too large, the pool cleaner 100 will simply circle on the water surface, failing to clean the surface.
[0116] To reduce the curvature of the movement path of the pool cleaner 100, two water guide tubes 560 are provided on the water surface cleaning assembly 520 to define two water flow channels 561. The two water guide tubes 560 are connected end to end, that is, one end of each water guide tube 560 is on the same side as the first water surface inlet 525, and the other end is on the same side as the second water surface inlet 526. When the pool cleaner 100 is running, the water guide tubes 560 are partially or completely submerged below the water surface (for example, the height of the submerged part of the water guide tube 560 is 80% or more of its total height), providing guidance for the movement of the pool cleaner 100 to make it move in a straight line. After the curvature of the movement path of the pool cleaner 100 is reduced, the pool cleaner 100 runs on the water surface, and after colliding with the pool wall, it runs in the opposite direction, thus cleaning the entire water surface.
[0117] like Figure 12 and Figure 15 As shown, the top of the water surface cleaning assembly 520 is provided with a drain outlet 570 that communicates with the water surface chamber 522. The drain outlet 570 and the water surface interface 529 are respectively provided on opposite sides of the water surface cleaning assembly 520.
[0118] When the sink cleaner 100 is operating normally, the drain outlet 570 is above the water surface and does not affect the operation of the sink cleaner 100. When the sink cleaner 100 has finished working and needs to be removed for cleaning, the sink cleaner 100 is flipped over, and the water will be discharged from the drain outlet 570. This prevents water from remaining in the inner cavity 202 and the water surface chamber 522, which would make the machine heavier and make it difficult to remove dirt left in the inner cavity 202 and the water surface chamber 522.
[0119] Furthermore, the drain outlet 570 is covered with a filter screen to prevent dirt from flowing out of the drain outlet 570.
[0120] Thus, this application satisfactorily describes the structure of the pool cleaner 100 and its two working configurations (pool bottom cleaning configuration and water surface cleaning configuration). By replacing different cleaning components 500 with the main unit 200, this application enables the pool cleaner 100 to have both pool bottom cleaning and water surface cleaning functions, thereby eliminating the need for separate pool bottom cleaners and water surface cleaners and effectively reducing costs.

Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
