The water sprayed from the water spray port 31 enters the auxiliary water spray device 4 through the auxiliary water inlet 411, and the auxiliary water spray port 421 is used for spraying water to adjust the running trajectory of the water surface cleaner.

[0036] When it is necessary to clean the swimming pool or other artificial pools, the water surface cleaner is placed in the corresponding artificial pool, and the impeller assembly 2 rotates relative to the housing 1 to generate suction, so that water near the first water inlet 12 flows through the first water inlet 12 into the water inlet channel 11, then enters the impeller assembly 2 through the water outlet 13 and then enters the volute 3, and finally flows out from the water spray port 31. The water sprayed from the water spray port 31 then enters the auxiliary water spray device 4 through the auxiliary water inlet 411, and finally is sprayed out from the auxiliary water spray port 421. The present application is provided with a volute assembly, and the volute 3 can rotate relative to the shell 1 under the drive of the water flow to change the travel direction of the water surface cleaner. The present application is also provided with an auxiliary water spraying device 4, and the auxiliary water inlet 411 is arranged toward the first water inlet 12, so that the water flow sprayed from the water spray port 31 can utilize its own impact force, and there is no need to add an additional power mechanism to provide power for the water flow to enter the auxiliary water inlet 411. The sprayed water flow can be sprayed into the auxiliary water spraying device 4, and then sprayed out again from the auxiliary water spray port 421, so that the kinetic energy of the water sprayed from the water spray port 31 can be reused. The present application drives the water surface cleaner to move through the force when the water spray port 31 and the auxiliary water spray port 421 spray water, adjusts the running trajectory of the water surface cleaner, and can save energy and improve the utilization rate of water energy.

[0037] refer to Figure 1-Figure 3 The auxiliary water spraying device 4 includes a first pipe 41 and a second pipe 42 that are connected to each other. An auxiliary water inlet 411 is opened on the side of the first pipe 41 close to the first water inlet 12, and an auxiliary water spraying port 421 is opened on the side of the second pipe 42 away from the first water inlet 12. When the volute 3 sprays water toward the first direction 15, the water spraying port 31 and the auxiliary water inlet 411 are arranged opposite to each other, and the water surface cleaner keeps moving forward. When the volute 3 sprays water toward the second direction 16, the water spraying port 31 and the auxiliary water inlet 411 are arranged away from each other, and the water surface cleaner keeps moving backward.

[0038] Specifically, the first pipe 41 is arranged in the middle of the second pipe 42, the first pipe 41 is arranged vertically, and the diameter of the auxiliary water inlet 411 is not less than the diameter of the water spray port 31, the second pipe 42 is arranged horizontally, and the number of the auxiliary water spray ports 421 is at least two. When the number of the auxiliary water spray ports 421 is two, the two auxiliary water spray ports 421 are arranged at opposite ends of the second pipe 42, and the auxiliary water inlet 411 is arranged between the two auxiliary water spray ports 421.

[0039] Specifically, the second pipe 42 includes a main pipe 422 and at least two branch pipes 423. The first pipe 41 is arranged in the middle of the main pipe 422. When the number of branch pipes 423 is two, the two branch pipes 423 are arranged at opposite ends of the main pipe 422. Each branch pipe 423 is provided with an auxiliary water spray port 421, and the axial direction of the branch pipe 423 is parallel to the first direction 15, so that the water spraying direction of the auxiliary water spray port 421 is roughly parallel to the moving direction of the water surface cleaner.

[0040] refer to Figure 2 The water surface cleaner of the present application further comprises a water inlet platform 5, which is arranged at the first water inlet 12, and a through hole 51 is opened on the side wall of the water inlet platform 5, and the through hole 51 is used for the inflow of water flow.

[0041] Specifically, there are multiple through holes 51 , and the multiple through holes 51 are arranged at intervals. Furthermore, the through holes 51 are in a long strip shape.

[0042] refer to Figure 5 The water surface cleaner of the present application also includes a baffle 52, one end of which is rotatably connected to the side wall of the water inlet platform 5, and the end of the baffle 52 away from the water inlet platform 5 can be rotated in a direction close to or away from the water inlet platform 5. The baffle 52 is used to open or close the first water inlet 12. Water flows in through the first water inlet 12, flows through the top surface of the water inlet platform 5 and the top surface of the baffle 52 in sequence, and then enters the water inlet channel 11.

[0043] When the water surface cleaner is working normally, the water inlet platform 5 is located below the horizontal plane and has a certain height difference with the horizontal plane. The baffle 52 is arranged below the water inlet platform 5, and there is a certain height difference between the top surface of the baffle 52 and the top surface of the water inlet platform 5. When the water surface cleaner starts to work, the water flow impacts the baffle 52, causing the baffle 52 to rotate to be parallel to the horizontal plane, so as to facilitate the entry of garbage in the swimming pool. When the water surface cleaner stops working, the baffle 52 returns to its natural state. At this time, the baffle 52 is roughly vertical to the horizontal plane, preventing the garbage inside the shell 1 from being discharged to the outside of the shell 1 through the first water inlet 12.

[0044] The present application is provided with a water inlet platform 5, which can play a role in guiding the water flow. There is a certain height difference between the water inlet platform 5 and the baffle 52, and the combination of the two facilitates the accelerated entry of water.

[0045] refer to Figure 1 , Figure 5 and Figure 8The water surface cleaner of the present application also includes a filter assembly 6, which is disposed in the water inlet channel 11. The filter assembly 6 includes a first filter screen 61 and a second filter screen 62, both of which are disposed in the water inlet channel 11, and the second filter screen 62 is disposed in the first filter screen 61, and the aperture of the filter hole of the second filter screen 62 is smaller than the aperture of the filter hole of the first filter screen 61. The present application is provided with a double-layer filtering device, one layer of coarse filtering and one layer of fine filtering, the first filter screen 61 is used to filter large garbage such as leaves and fruits, and the second filter screen 62 can filter fine garbage such as dust.

[0046] refer to Figure 4 and Figure 7 The water surface cleaner of the present application also includes a motor 7. A accommodating chamber 14 is also provided inside the shell 1. The accommodating chamber 14 and the water inlet channel 11 are arranged adjacent to each other. The motor 7 is arranged in the accommodating chamber 14. The motor 7 passes through the accommodating chamber 14 and is connected to the impeller assembly 2. The motor 7 can output positive and negative torques. The motor 7 is used to drive the impeller assembly 2 to rotate.

[0047] Specifically, the accommodating chamber 14 is sealed to prevent water from entering the accommodating chamber 14 .

[0048] refer to Figure 6 and Fig. 9 The present application also includes a base 71, which is arranged at the water outlet 13, the volute 3 is rotatably arranged at the bottom of the base 71, the impeller assembly 2 is arranged between the volute 3 and the base 71, and the base 71 is also provided with a second water inlet 711, the motor 7 is also connected to the impeller assembly 2 through the second water inlet 711, and the second water inlet 711 is connected to the water spray port 31.

[0049] Specifically, the volute 3 is detachably mounted on the base 71 .

[0050] The present application also includes a limit assembly, which is disposed at the bottom of the base 71 and is used to limit the rotation angle of the volute 3 relative to the base 71 .

[0051] Specifically, the limit assembly includes a first limit block and a second limit block that are relatively arranged. The first limit block and the second limit block are spaced apart at the bottom of the base 71. When the volute 3 rotates to abut against the first limit block, the volute 3 sprays water toward the first direction 15, and the water surface cleaner moves toward the second direction 16. The first direction 15 and the second direction 16 are in opposite directions. When the volute 3 rotates to abut against the second limit block, the volute 3 sprays water toward the second direction 16, and the water surface cleaner moves toward the first direction 15.

[0052] Specifically, the first direction 15 is the backward direction of the water surface cleaner, and the second direction 16 is the forward direction of the water surface cleaner.

[0053] The motor 7 outputs torque to drive the impeller assembly 2 to rotate, and the water flows into the impeller assembly 2 through the first water inlet 12, and then drives the volute 3 to rotate under the impact of the water flow. When the volute 3 rotates to the first limit block, it is limited and cannot continue to rotate, thereby determining the direction of the water outlet 31. The water flow is accelerated by the impeller assembly 2 and thrown out to the water outlet 31, driving the water surface cleaner to move in the direction opposite to the water outlet 31.

[0054] Switching the output torque direction of the motor 7 can change the rotation direction of the impeller assembly 2 and the volute 3. When the volute 3 rotates in the other direction to the second limit stop, the volute 3 is limited and cannot continue to rotate, thereby determining the water spraying direction of the water spray port 31, thereby changing the moving direction of the water surface cleaner.

[0055] refer to Fig.10 The impeller assembly 2 includes a first cover plate 21, a second cover plate 23, and a plurality of blades 22 arranged between the first cover plate 21 and the second cover plate 23. The first cover plate 21 is connected to the second cover plate 23. Specifically, the output shaft of the motor 7 passes through the first cover plate 21 and is connected to the second cover plate 23 to drive the first cover plate 21 and the second cover plate 23 to rotate.

[0056] refer to Fig.10 Each blade 22 has a hinged end 221 and a swing end 212, the hinged end 221 is hinged to the first cover plate 21 and / or the second cover plate 23, and the impeller assembly 2 further includes a plurality of retaining ribs 24 mounted on the first cover plate 21 and / or the second cover plate 23 for limiting the position of the swing end 212. After being impacted by the water flow, the blade 22 swings with the hinged end 221 as the center of the circle, and the swing end 212 cannot continue to swing after abutting against the corresponding retaining rib 24, forming a fixed angle.

[0057] refer to Fig.12 When the impeller assembly 2 rotates clockwise, each blade 22 is subjected to water flow resistance and swings in the direction of the arrow in the figure until it abuts against the corresponding retaining rib 24, forming a high-efficiency backward curved impeller state as shown in the figure. Fig.11 When the impeller assembly 2 rotates counterclockwise, each blade 22 is subjected to water flow resistance and swings in the direction of the arrow in the figure until it abuts against another retaining rib 24, forming a high-efficiency backward curved impeller state as shown in the figure. Therefore, the impeller assembly 2 in this embodiment can automatically adjust the angle of each blade 22 according to the rotation direction to adapt to the water flow and improve work efficiency.

[0058] Specifically, if the retaining ribs 24 are not provided, the rotation angle of the blade 22 is 360°. In this embodiment, two adjacent retaining ribs 24 limit the swing angle range of the corresponding blade 22 to 90°-160°.

[0059] The water surface cleaner also includes a circuit board, which is in communication with the motor 7. The circuit board is used to control the start and stop of the motor 7. The circuit board 00 is also used to adjust the speed of the motor shaft of the motor 7. The circuit board is also used to switch the forward and reverse rotation of the motor 7. In this embodiment, the circuit board is arranged in the accommodating cavity 14 to prevent water from entering the circuit board.

[0060] refer to Figure 1 The water surface cleaner also includes a sensor 8, which is arranged on the outer wall of the housing 1. The sensor 8 is connected to the circuit board in communication. When the water surface cleaner touches the wall, a signal is sent, and the signal is transmitted to the circuit board. At the same time, the circuit board switches the operation of the motor 7, thereby changing the movement direction of the water surface cleaner. The sensor 8 can determine whether the water surface cleaner hits an obstacle or a swimming pool wall. When the sensor 8 detects that the water surface cleaner hits an obstacle or a swimming pool wall, it sends a signal to the circuit board, so that the circuit board switches the rotation direction of the motor 7, thereby changing the movement direction of the water surface cleaner.

[0061] Furthermore, the running track of the water surface cleaner can be set in advance, and then the sensor 8 and the circuit board can be used to control the water surface cleaner to clean the artificial pool to be cleaned along the set running track. Specifically, the sensor 8 determines whether the water surface cleaner reaches the turning point of the running track, and then feeds back to the circuit board. The circuit board controls the motor 7 according to the feedback of the sensor 8 to ensure that the water surface cleaner does not deviate from the preset running track.

[0062] The water surface cleaner further comprises a power supply structure, which is used to supply power to the water surface cleaner, and the power supply structure is arranged in the accommodating cavity 14 .

[0063] The water surface cleaner also includes a solar panel, which is arranged at the top of the inner surface of the shell 1. The solar panel is electrically connected to the power supply structure to supply power to the power supply structure.
