[0002] With the improvement of people's material living standards, in order to pursue a higher quality of life, swimming pools have become a common place for people's leisure and entertainment. Whether it is a private swimming pool or a public swimming pool, the cleanliness of the pool water is the primary concern of people. Usually, to keep it clean, the swimming pool water needs to be changed regularly, and the swimming pool also needs to be cleaned regularly. The traditional cleaning method is generally manual cleaning, which is not only time-consuming and laborious but also causes waste of water resources.

[0003] In recent years, in order to save water resources and reduce manual labor, automatic swimming pool cleaners have been introduced, which can automatically clean the swimming pool without draining the water.

[0004] The existing electric robots for cleaning pools use multiple motors to drive the tracks to control steering when turning, or use an electric pump impeller to drive a rotating device in cooperation with a limiting device to achieve water discharge in different directions and push the machine through the water discharge force. However, a specially designed impeller is used in cooperation with a rotatable nozzle to achieve forward and reverse thrust. There are moving parts outside, which are prone to accidental jamming, resulting in the inability to flexibly adjust the direction; and multiple motors are placed in the sealed compartment inside the robot, occupying a large space, having a complex structure, and a relatively high production cost.

[0030] Specific descriptions are made for the preferred embodiments provided by the present utility model according to the attached drawings.

[0031] Figures 1 to 12 , which is a preferred embodiment of a single - power dual - direction moving pool cleaning robot provided by the present utility model. As Figures 1 to 12As shown in the figure, the single-power two-way moving pool cleaning robot includes a housing 10. A cavity 11 is formed inside the housing 10. An inlet 12 and an outlet 13 communicating with the cavity 11 are provided on the housing 10. A filtering unit 14 for filtering debris is provided inside the cavity 11. A power mechanism 20 for driving the water in the cavity to be discharged from the outlet to drive the movement of the housing is further provided inside the housing 10. The power mechanism 20 includes a driving motor 21 connected to a main control module 40 and two rotary drainers 24 respectively arranged on the front side and the rear side of the driving motor for driving the water to be discharged from the outlet. The main driving shaft 211 of the driving motor 21 indirectly drives two driven shafts 22. A clutch gear assembly 23 for driving the driven shaft to rotate according to the rotation direction of the main driving shaft is provided between the main driving shaft 211 and the driven shaft 22. The driven shaft 22 drives the rotary drainer 23 to rotate. The housing 10 is provided with a front water outlet channel 131 and a rear water outlet channel 132 corresponding to the two rotary drainers 24 respectively. The front water outlet channel 131 and the rear water outlet channel 132 are both communicated with the cavity 11. When working, water enters the cavity 11 from the inlet 12. After being filtered by the filtering unit 14, when the driving motor 21 rotates, by using the clutch gear assembly 23, according to the rotation direction of the main driving shaft 211, the rotary drainer 24 at the front end or the rotary drainer 24 at the rear end is driven to rotate, and the water is discharged from the corresponding water outlet channel at a high speed, generating a reaction force to push the robot to move. In this way, the forward and reverse rotations of the driving motor 21 are fully utilized to drive the single-power two-way movement of the robot, reducing the overall cost and saving the space of the sealed chamber. The rotary drainer 24 can be an impeller or other structures that can drain water to generate power.

[0032] The clutch gear assembly 23 includes a driving gear 231 that rotates synchronously with the main driving shaft 211 and a driven gear 232 sleeved on the driven shaft 22. The driven gear 232 meshes with the driving gear 231. A ratchet 233 for controlling the synchronous rotation of the driven shaft and the driven gear is provided inside the driven gear 232. The ratchet 233 includes a ratchet disc 2331 that rotates synchronously with the driven shaft 22. A plurality of pawls 2332 are provided on the ratchet disc 2331 through pin shafts. A ratchet groove 2321 for cooperating with the front end of the pawl is provided inside the driven gear 232. A return spring piece 2333 is cooperated with the tail end of the pawl 2332. The return spring piece 2333 is installed on the ratchet disc 2331. The pawl 2332 is in an open state under the action of the return spring piece 2333. When the rotation direction of the driven gear 232 is opposite to the opening direction of the pawl 2332, the ratchet groove 2321 on the driven gear 232 cooperates with the front end of the pawl 2332 to drive the ratchet disc 2331 to rotate, and the driven shaft 22 rotates synchronously, thereby driving the rotary drainer 24 on the driven shaft 22 to rotate.

[0033] As Figure 6As shown in the figure, when the main drive shaft 211 of the drive motor 21 drives the driving gear 231 to rotate clockwise, the driven gear 232 on the front driven shaft 22 is driven to rotate counterclockwise. The rotation direction of the driven gear 232 is opposite to the opening direction of the pawl 2332. The front end of the opened pawl 2332 on the ratchet disc 2331 is inserted into the ratchet groove 2321. When the driven gear 232 continues to rotate, it pushes the ratchet disc 2331 to rotate counterclockwise. In this way, the front driven shaft 22 and the rotary drainer 24 rotate synchronously, discharging water from the front water outlet channel 131 at high speed, generating a reaction force, and the entire cleaning robot moves backward. The driven gear 232 on the rear driven shaft 22 meshes with the driving gear 231. The rear driven gear 232 rotates counterclockwise, and the rotation direction of the rear driven gear 232 is the same as the opening direction of the pawl 2332. The side wall of the ratchet groove 2321 in the rotating driven gear 232 will exert a squeezing force on the opened pawl 2332, causing the pawl 2332 to close towards the center of the ratchet disc 2331. In this way, the driven gear 231 on the rear driven shaft 22 will not drive the ratchet disc 2321, the driven shaft 22 and the rotary drainer 24 to rotate. Similarly, when the main drive shaft 211 of the drive motor 21 drives the driving gear 231 to rotate counterclockwise, the driven gear 231 on the front driven shaft 22 rotates clockwise, and the driven gear 231 will not drive the ratchet disc 2331, the driven shaft 22 and the rotary drainer 24 to rotate. The driven gear 231 on the front driven shaft 22 rotates clockwise, driving the ratchet disc 2331, the driven shaft 22 and the rotary drainer 24 to rotate, discharging water from the rear water outlet channel 132 at high speed, generating a reaction force, and the entire cleaning robot moves forward. The ratchet disc 2331 is placed inside the driven gear 231, and the driven gear 232 is provided with a placement groove for placing the ratchet disc 2331. And for aesthetics and to protect the ratchet 233, the driven gear 231 is also equipped with a cover body, and the cover body covers the placement groove.

[0034] The drive motor 21 is installed in the sealed chamber 30, and the sealed chamber 30 is placed in the housing 10. The sealed chamber 30 includes a chamber body 31 and a sealing cover 32 that cooperates with the chamber body. The drive motor 21 is placed inside the chamber body 31. There is an installation seat 33 below the sealing cover 32. The driving gear 231 and the two driven gears 232 are all placed on the installation seat 33. The main drive shaft 211 of the drive motor 21 passes through the installation seat 33 and is connected to the driving gear 231. One end of the driven shaft 22 passes through the sealing cover 32 and is connected to the ratchet disc 2331 inside the driven gear 232, and the other end of the driven shaft 22 is connected to the rotary drainer 24. A battery 100 is also placed inside the sealed chamber 30 to facilitate power supply to the drive motor 21.

[0035] The housing 10 includes a base 101 and an upper shell 102 mounted on the base. The cavity 11 is divided into a lower cavity 111 inside the base and an upper cavity 112 inside the upper shell 102. The filtering unit 14 is located between the upper cavity 112 and the lower cavity 111. The lower cavity 111 is connected to a water inlet 12, and the upper cavity 112 is connected to a water outlet 13. The water outlet 12 is provided at the front end and the rear end of the upper shell 102, and the water outlet 12 is connected to the front water outlet channel and the rear water outlet channel. The filtering unit 14 is a filter screen.

[0036] As Figure 10 shown, a front wing 15 is installed above the water outlet corresponding to the front water outlet channel 131. A front flap 16 is pivotally installed below the front wing. The bottom plate of the front wing 15 is provided with a plurality of front positioning grooves 151, and the front flap 16 is provided with front positioning protrusions 161 that cooperate with the front positioning grooves 151; As Figure 11 shown, a rear wing 17 is installed above the channel outlet of the rear water outlet channel on the housing. A rear flap 18 is pivotally installed below the rear wing 17. The bottom plate of the rear wing 17 is provided with a plurality of rear positioning grooves 171, and the rear flap 18 is provided with rear positioning protrusions 181 that cooperate with the rear positioning grooves; The water thrown out at high speed by the rotary drainer 24 flows through the front flap 34 or the rear flap 36. By adjusting the angle of the front flap 34 or the rear flap 36 as needed, the curvature of the robot's walking trajectory can be adjusted, facilitating the cleaning of the swimming pool.

[0037] The upper shell 102 includes an outer shell 1021 and an inner shell 1022. The outer shell 1021 is installed on the base 101, and the inner shell 1022 is sleeved inside the outer shell 1021. The upper cavity 112 is formed inside the inner shell 1022. The front water outlet channel 131 and the rear water outlet channel 132 are respectively arranged inside the front end and the rear end of the inner shell 1022. The sealing chamber 30 is placed between the base 101 and the inner shell 1022; Front through grooves 10211 and rear through grooves 10212 for placing the front end and the rear end of the inner shell 1022 are respectively provided at both ends of the outer shell 1021. The front wing 15 and the rear wing 17 are also pivotally installed at both ends of the outer shell 1021. The outer shell 1021 and the base 101 are connected by a snap connection, which is convenient for disassembly and assembly and reduces the weight.

[0038] At least one drain port 1011 is further provided on the base 101, and each drain port 1011 is provided with a movable check valve cover 1012; The check valve cover 1012 can be pivotally installed on the base 101. The drain port 1011 and the check valve cover 1012 can be used to drain the accumulated water inside the machine; When the machine is working, due to the rotation of the impeller to drain water outward, negative pressure is generated inside the machine. Under the action of the external water flow, the check valve cover 1012 is in a closed state, closing the drain port 1011; When the machine stops working and is lifted out of the water surface by the user, the water pressure of the accumulated water inside the machine will push open the check valve cover 1012 and flow out from the drain port 1011, thereby achieving the purpose of draining the accumulated water.

[0039] The bottom of the housing 10 is also provided with traveling wheels 50. The traveling wheels 50 are installed at the bottom of the base 101. The traveling wheels 50 support the housing 10, so that the housing 10 has a certain ground clearance, ensuring that water can enter the cavity 11 from the water inlet 12.

[0040] The main control module 40 is placed in the sealed chamber 30. The main control module 40 is connected to the drive motor 21. A capacitance induction module 41 is installed at the top of the housing 10. The capacitance induction module 41 is connected to the main control module 40. When there is water here, the capacitance induction module 41 will generate an inductance signal. Through this signal, it is judged whether the machine is in the water inlet state, so as to facilitate the control of the motor startup.

[0041] The specific working process of this pool cleaning robot is as follows: (1) Water enters from the water inlet 12 at the bottom of the lower cavity 111, passes through the filtering unit 14 for filtering, and enters the upper cavity 112; (2) When the drive motor 21 is started and the drive motor 21 drives the driving gear 231 to rotate clockwise, it drives the rotary drainer 24 on the driven shaft 22 at the front side to rotate, and the water is discharged at high speed from the front water outlet channel 131, generating a reaction force, so that the whole cleaning robot moves backward; when the drive motor 21 drives the driving gear 231 to rotate counterclockwise, it drives the rotary drainer 24 on the driven shaft 22 at the rear side to rotate, and the water is discharged at high speed from the rear water outlet channel 132, generating a reaction force, so that the whole cleaning robot moves forward; (3) According to needs, adjust the angles of the front paddle 16 and the rear paddle 18, and the water flow angles discharged from the front water outlet channel 131 and the rear water outlet channel 132 can be changed, thereby changing the movement trajectory of the robot.

[0042] In summary, the technical solution of the present invention can fully and effectively achieve the above-mentioned invention purpose, and the structure and functional principle of the present invention have been fully verified in the embodiments, and can achieve the expected effect and purpose.
