Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a remotely controllable pool cleaning robot. Background Art

[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, which can automatically clean the swimming pool without draining water.

[0004] The existing pool cleaning electric robots use multiple motors to drive tracks to control steering when turning, or use an electric pump impeller to drive a rotating device and cooperate with a limiting device to achieve water output in different directions and push the machine through the water output force. However, the use of a specially designed impeller in cooperation with a rotatable nozzle to achieve forward and reverse thrust has moving parts externally, which is prone to accidental jamming, resulting in the inability to flexibly adjust the direction; the motor controls the track to rotate, which is inconvenient for steering, occupies a large space, has a complex structure, and a high production cost.

[0034] Specific descriptions are given to the preferred implementation modes provided by the present utility model according to the attached drawings.

[0035] Figures 1 to 16 , is the preferred implementation mode of a remotely controllable pool cleaning robot provided by the present utility model. As Figures 1 to 7As shown in the figure, the remotely controllable pool cleaning robot includes a main body, which 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 in the cavity 11. The main body further includes a power device connected to the main control module 30 of the main body for discharging the water in the cavity from the outlet 13 so that the housing moves along a linear trajectory or an arc trajectory. The main body is connected with a buoy 40 for wireless remote control. A buoy control module 41 is provided inside the buoy 40. The buoy control module 41 is connected with a transceiver module 42, a first infrared emission module 43 and a first infrared reception module 44. The main control module 30 of the main body is connected with a second infrared reception module 31 corresponding to the first infrared emission module and a second infrared emission module 32 corresponding to the second infrared reception module. In this way, the controller of the operator uses a Bluetooth, WIFI, infrared or other general remote control scheme to send a control signal to the buoy. After the transceiver module 42 inside the buoy receives the control signal, it converts the control signal into a transmission signal and emits it by the first infrared emission module 43. After the second infrared reception module 31 on the main body receives the signal, it is transmitted to the main control module 30. The main control module 30 controls the direction and speed of the traveling device 20 inside the housing, realizes rotation in any direction, and can move at any time according to the will of the operator. At the same time, various states of the main body can also be transmitted to the controller on the water surface through the remote control receiving converter in the opposite way, so that the operator can understand the machine state.

[0036] The buoy 40 includes a floating seat 401 and a joint seat 402 connected to the floating seat. An insertion socket 17 for inserting the joint seat is provided on the housing 10. The buoy control module 41 and the transceiver module 42 are installed inside the floating seat 401. The first infrared emission module 42 and the second reception module 43 are installed inside the joint seat 402. During use, the joint seat 402 is inserted into the insertion hole 13 on the surface of the housing 10, and the floating seat 401 is exposed above the water surface, which is convenient for receiving the signal sent by the operator via the controller. A first transparent cover 171 is provided inside the insertion socket 17. The second infrared reception module 31 and the second infrared emission module 32 are inside the second transparent cover 10001 inside the housing 10, so as not to affect the emission and reception of infrared signals. The first transparent cover 171 is inside the insertion socket 17 and can seal the insertion socket to prevent water from entering from the top of the housing.

[0037] A photovoltaic panel 44 is further provided on the floating seat 401. The photovoltaic panel 44 is connected to the buoy control module 41. The buoy control module 41 is connected with a buoy battery 45. In this way, the photovoltaic panel 44 converts sunlight into electric energy and stores it in the buoy battery 45 to supply power to other modules. The buoy control module is further connected with a reset button 46, and the reset button 46 is installed on the back of the floating seat 401.

[0038] As Figure 12As shown, the power mechanism 20 includes a drive 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 drive motor to drive water to drain from the water outlet. The main drive shaft 211 of the drive motor 21 indirectly drives two driven shafts 22. A clutch gear assembly 23 for driving the driven shafts to rotate according to the rotation direction of the main drive shaft is arranged between the main drive shaft 211 and the driven shafts 22. 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 filter unit 14, when the drive motor 21 rotates, the clutch gear assembly 23 is used to drive the rotary drainer 24 on the front side or the rotary drainer 24 on the rear side to rotate according to the rotation direction of the main drive shaft 211, and the water is discharged from the corresponding outlet channels at high speed to generate a reaction force to push the robot to move. In this way, the forward and reverse rotations of the drive 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 that can drain water to generate power.

[0039] As Figure 10 shown, 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 drive 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 flowing out from each outlet channel are all on a horizontal straight line, the robot moves in a straight line. When the rotation speeds of the drive 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.

[0040] The two front water outlet channels 151 on both sides in the front water outlet channel 151 are arranged obliquely opposite to each other, and the two rear water outlet channels 152 on both sides in the rear water outlet channel 152 are arranged obliquely opposite to each other. Considering that the rotational speeds of the rotary drainers 24 in the same-side water outlet channels are inconsistent, it is more conducive to realizing steering. The other front water outlet channels between the front water outlet channels 151 on both sides can be arranged along a horizontal straight line, or can be arranged symmetrically along the midline parallel to the inclination direction of the front water outlet channels 151 on the side; correspondingly, the other rear water outlet channels between the rear water outlet channels 152 on both sides can be arranged along a horizontal straight line, or can be arranged symmetrically along the midline parallel to the inclination direction of the rear water outlet channels 152 on the side. 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 arranged obliquely, and the front water outlet channel in the middle is arranged along a horizontal straight line.

[0041] As Figure 13 As shown, 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, and 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.

[0042] As Figure 10As 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, and water is discharged 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, and water is discharged 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.

[0043] The drive motor 21 in each power mechanism 20 is installed in the sealing chamber 16. The sealing 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. An installation seat 163 is provided below the sealing cover 162. 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 sealing 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 sealing chamber 16 to facilitate power supply to the drive motor 21.

[0044] The housing 10 includes a base 101 and an upper housing 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 housing 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 housing 102. The filtering unit 14 is a filter screen.

[0045] The upper housing 102 includes an outer housing 1021 and an inner housing 1022. The outer housing 1021 is mounted on the base 101, and the inner housing 1022 is inserted into the outer housing 1021. The upper cavity 112 is formed within the inner housing 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 housing 1022. A sealing chamber 16 is placed between the base 101 and the inner housing 1022. Front through grooves 10211 and rear through grooves 10212 for placing the front end and the rear end of the inner housing 1022 are respectively provided at both ends of the outer housing 1021. The outer housing 1021 and the base 101 are connected by a snap connection.

[0046] 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 outward, 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, thereby achieving the purpose of draining the accumulated water. A traveling wheel 50 is further provided at the bottom of the housing 10. The traveling wheel 50 is mounted at the bottom of the base 101. The traveling wheel 50 supports 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.

[0047] As a preferred embodiment, such as Figure 10As 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.

[0048] As needed, one of the two power mechanisms 20 can be started alone, or both can be started simultaneously; when a single 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.

[0049] When both drive motors 21 are started and the main drive shaft 211 drives the corresponding driving gear 231 to rotate clockwise, as Figure 14 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 driven gear 232 on the rear side 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 generate 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 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 rotational speeds of the two drive motors 21 are the same, the rotational speeds of the two rotary drainers 24 on the front side driven by the two drive motors 21 are the same, and the robot moves backward in a straight line; when the rotational speeds of the two drive motors 21 are different, the rotational speeds of the two rotary drainers 24 on the front side driven by the two drive motors 21 are different, and the water jets generate a thrust difference, causing the direction of the robot to deviate, and the robot moves along an arc trajectory.

[0050] Similarly, when both driving motors 21 are started and the main drive shaft 211 drives the corresponding driving gear 231 to rotate counterclockwise, as Figure 15 shown, it drives the driven gear 232 on the front-side driven shaft 22 to rotate clockwise. The driven gear 232 does not drive the ratchet disc 2331, the driven shaft 22, and the rotary drainer 24 to rotate; while the driven gear 232 on the rear-side driven shaft 22 rotates clockwise, and the driven gear 232 drives the ratchet disc 2331, the driven shaft 22, and the rotary drainer 24 to rotate, discharging water from the two rear water discharge channels 152 at high speed, generating a reaction force, and the entire cleaning robot moves forward. It should be noted that when the rotational speeds of the two driving motors 21 are the same, the rotational speeds of the two rotary drainers 24 on the rear side driven by the two driving motors 21 are the same, and the robot moves straight forward; when the rotational speeds of the two driving motors 21 are different, the rotational speeds of the two rotary drainers 24 on the rear side driven by the two driving motors 21 are different, and the thrust difference generated by the ejected water flow causes the direction of the robot to deviate, and the robot moves along an arc trajectory.

[0051] 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.
