Description

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a dual-power pool cleaning robot. Background Technique

[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 maintain cleanliness, the swimming pool water needs to be replaced 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, pool automatic cleaning machines have been introduced to automatically clean swimming pools without draining water.

[0004] The existing pool cleaning electric robots 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 special-designed impeller is used in cooperation with a rotatable nozzle to achieve forward and reverse thrusts. There are moving parts outside, which are prone to accidental jamming, resulting in the inability to flexibly adjust the direction; and the motor controls the track rotation, which is inconvenient for steering, occupies a large space, has a complex structure, and a high production cost.

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

[0031] Figures 1 to 12 , which is a preferred embodiment of a dual - power pool cleaning robot provided by the present utility model. As Figures 1 to 12 shown, the dual - power moving pool cleaning robot includes a housing 10. A cavity 11 is formed inside the housing. An inlet 12 and an outlet 13 communicating with the cavity 11 are provided on the housing. A filtering unit 14 for filtering debris is provided inside the cavity 11; A power device for discharging the water in the cavity from the outlet 13 so that the housing moves along a linear trajectory or an arc - shaped trajectory is further provided inside the housing 10. The power device includes at least two power mechanisms 20 for individual use or combined use. By using a single power mechanism 20 or multiple power mechanisms 20 in combination, thrusts of different magnitudes or different directions are generated to achieve the movement of the machine along a linear trajectory or an arc - shaped trajectory, reducing the overall cost.

[0032] The power mechanism 20 includes a driving motor 21 connected to the main control module 30 and two rotary drainers 24 respectively arranged on the front side and the rear side of the driving motor to drive water to drain from the water outlet. The main driving shaft 211 of the driving motor 21 indirectly drives two driven shafts 22. A clutch gear assembly 23 is arranged between the main driving shaft 211 and the driven shafts 22 to drive the driven shafts to rotate according to the rotation direction of the main driving shaft. The driven shafts 22 drive the rotary drainers 24 to rotate. An outlet channel group 15 corresponding to each rotary drainer 24 is arranged in the housing 10. The outlet channel group 15 is communicated with the water outlet 13 and the cavity 11. When working, water enters the cavity 11 from the water inlet 12. After being filtered by the filtering unit 14, when the driving motor 21 rotates, by using the clutch gear assembly 23, the rotary drainer 24 on the front side or the rotary drainer 24 on the rear side is driven to rotate according to the rotation direction of the main driving shaft 211, and the water is discharged from the corresponding outlet channel at a high speed to generate 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 robot to move in two directions, reducing the overall cost and saving the space of the sealed chamber. The rotary drainer 24 can be an impeller or other structures capable of draining water to generate power.

[0033] The outlet channel group 15 includes at least two front outlet channels 151 arranged at the front end of the housing and at least two rear outlet channels 152 arranged at the rear end of the housing. Each front outlet channel 151 corresponds to the rotary drainer 24 on the front side respectively, and each rear outlet channel 152 corresponds to the rotary drainer 24 on the rear side respectively. In this way, by controlling the start, forward rotation or reverse rotation of the driving motor 21 in different power mechanisms, thrusts in different directions are generated to realize the movement of the machine along a straight track or an arc track. When the reaction forces of the water flows discharged from each outlet channel are all on a horizontal straight line, the robot moves in a straight line. When the rotation speeds of the driving motors 21 on the same side are inconsistent, the rotation speeds of the rotary drainers 24 in the outlet channels on the same side are inconsistent, and the ejected water flows generate a thrust difference to realize the turning of the robot.

[0034] Two front outlet channels 151 on the two side edges in the front outlet channels 151 are arranged obliquely opposite to each other, and two rear outlet channels 152 on the two side edges in the rear outlet channels 152 are arranged obliquely opposite to each other. Combining with the inconsistent rotation speeds of the rotary drainers 24 in the outlet channels on the same side, it is more conducive to realizing turning.

[0035] Among the other front water outlet channels in the front water outlet channel 151 that are between the two side front water outlet channels 151, they can be arranged along a horizontal straight line, or symmetrically along the center line and parallel to the inclination direction of the side front water outlet channels 151; correspondingly, among the other rear water outlet channels in the rear water outlet channel 152 that are between the two side rear water outlet channels 152, they can be arranged along a horizontal straight line, or symmetrically along the center line and parallel to the inclination direction of the side rear water outlet channels 152. For example, when there are 5 front water outlet channels at the front end of the housing, 4 of the front water outlet channels are inclined, and the front water outlet channel in the middle is arranged along a horizontal straight line.

[0036] The clutch gear assembly 23 includes a driving gear 231 that rotates synchronously with the main drive 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 that cooperates with the front end of the pawl is provided inside the driven gear 232. A return spring piece 2333 is provided at 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.

[0037] Such 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, it drives the driven gear 232 on the front driven shaft 22 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 at high speed from the front water outlet channel 131, generating a reaction force, and the entire cleaning robot moves backward; while the driven gear 232 on the rear driven shaft 22 meshes with the driving gear 231, and the rear driven gear 232 rotates counterclockwise. 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; while the driven gear 231 on the front driven shaft 22 rotates clockwise, the driven gear 231 drives the ratchet disc 2331, the driven shaft 22 and the rotary drainer 24 to rotate, discharging water at high speed from the rear water outlet channel 132, 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 fitted with a cover body, and the cover body covers the placement groove.

[0038] The drive motor 21 in each power mechanism 20 is installed in the sealed chamber 16. The sealed chamber 16 includes a chamber body 161 and a sealing cover 162 that mates with the chamber body. The drive motor 21 is placed inside the chamber body 161. Below the sealing cover 162 is provided an installation seat 163. The driving gear 231 and the two driven gears 232 are all placed on the installation seat 163. The main drive shaft 211 of the drive motor 21 passes through the installation seat 163 and is connected to the driving gear 231. The driven shaft 22 of the driven gear 232 passes through the sealing cover 162 and is connected to the rotary drainer 24. The main control module 30 is placed in the sealed chamber 16. The main control module 30 is connected to each drive motor 21, and the main control module 30 is used to control the start, forward rotation and reverse rotation of each drive motor 21. A battery 100 is also placed in the sealed chamber 16 to facilitate power supply to the drive motor 21.

[0039] 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 within the base and an upper cavity 112 within 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. The filtering unit 14 is a filter net.

[0040] The upper shell 102 includes an outer shell 1021 and an inner shell 1022. The outer shell 1021 is mounted on the base 101, and the inner shell 1022 is inserted into the outer shell 1021. The upper cavity 112 is formed within the inner shell 1022. A front water outlet channel 151 and a rear water outlet channel 152 are respectively provided within the front end and the rear end of the inner shell 1022. A sealing chamber 16 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 outer shell 1021 and the base 101 are connected by a snap-fit method.

[0041] At least one drain port 1011 is further provided on the base 101, and each drain port 1011 is equipped with a movable check valve cover 1012. The check valve cover 1012 can be pivotally mounted 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, since the rotary drainer 24 rotates to drain water outwards, negative pressure is generated inside the machine. Under the action of 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 the water will flow out from the drain port 1011, thus achieving the purpose of draining the accumulated water. A traveling wheel 40 is further provided at the bottom of the housing 10. The traveling wheel 40 is mounted at the bottom of the base 101. The traveling wheel 40 supports the housing 10, enabling the housing 10 to have a certain clearance from the ground, ensuring that water can enter the cavity 11 from the water inlet 12.

[0042] As a preferred embodiment, such as Figure 8As shown, the power device includes two power mechanisms 20, and the two power mechanisms 20 are provided with four rotary drainers 24. For the convenience of processing and installation, the two power mechanisms 20 are arranged side by side left and right, and the four rotary drainers 24 are arranged in pairs opposite to each other; correspondingly, the water outlet channel group 15 includes four water outlet channels, which are divided into two front water outlet channels 151 and two rear water outlet channels 152. The two front water outlet channels 151 and the two rear water outlet channels 152 are arranged obliquely opposite to each other. The intersection of the center lines of the two front water outlet channels at the rear end is outside the housing and outside the robot, and the intersection of the center lines of the two rear water outlet channels at the front end is outside the housing, that is, the front water outlet channels 151 and the rear water outlet channels 152 on the same horizontal line are arranged in a V shape.

[0043] As needed, either one of the two power mechanisms 20 can be started independently, or both can be started simultaneously; when only one power mechanism 20 is started, according to the rotation direction of the drive motor 21, the rotary drainer 24 on the front side discharges water at high speed or the rotary drainer 24 on the rear side discharges water at high speed, and discharges water from the corresponding water outlet channel, generating a reaction force to push the robot to move.

[0044] When both drive motors 21 are started and the main drive shaft 211 drives the corresponding drive gear 231 to rotate clockwise, as Figure 10 shown, it drives the driven gear 232 on the driven shaft 22 on the front side 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 slot 2321. When the driven gear 232 continues to rotate, it pushes the ratchet disc 2331 to rotate counterclockwise. In this way, the driven shaft 22 and the rotary drainer 24 on the front side rotate synchronously, discharging water from the two front water outlet channels 151 at high speed, generating a reaction force, and the entire cleaning robot moves backward; while the driven gear 232 on the rear side 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 slot 2321 in the rotating driven gear 232 will exert an extrusion 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 232 on the rear side will not drive the ratchet disc 2331, the driven shaft 22 and the rotary drainer 24 to rotate. It should be noted that when the two drive motors 21 drive the two rotary drainers 24 on the front side to rotate at the same speed, the robot moves backward in a straight line; when the two drive motors 21 drive the two rotary drainers 24 on the front side to rotate at different speeds, the direction of the robot deviates, and the robot moves along an arc trajectory.

[0045] Similarly, when both drive motors 21 are started and the main drive shaft 211 drives the corresponding drive gear 231 to rotate counterclockwise, as Figure 11As shown, it drives the driven gear 232 on the front-side driven shaft 22 to rotate clockwise. The driven gear 232 will not drive the ratchet disc 2331, the driven shaft 22 and the rotary drainer 24 to rotate. However, when the driven gear 232 on the rear-side driven shaft 22 rotates clockwise, the driven gear 232 drives the ratchet disc 2331, the driven shaft 22 and the rotary drainer 24 to rotate, and discharges water from the two rear water discharge channels 152 at high speed, generating a reaction force, and the whole cleaning robot moves forward. It should be noted that when the two drive motors 21 drive the two rear-side rotary drainers 24 to rotate at the same speed, the robot moves straight forward; when the two drive motors 21 drive the two rear-side rotary drainers 24 to rotate at different speeds, the direction of the robot deflects and the robot moves along an arc trajectory.

[0046] In summary, the technical solution of the present utility model can fully and effectively achieve the above-mentioned utility model purpose, and the structure and functional principle of the present utility model have been fully verified in the embodiments, and can achieve the expected efficacy and purpose. Without departing from the principle and essence of the present utility model, various changes or modifications can be made to the embodiments of the utility model. Therefore, the present utility model includes all replacement contents within the scope mentioned in the patent application scope, and any equivalent changes made within the patent application scope of the present utility model fall within the scope of the patent applied for in this case.
