Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments may be combined with each other without conflict.

The walking drive structure of traditional pool cleaning robots usually requires a combination of underwater propellers, pulley drives and other motor systems to drive the robot to the target area. Its complex structure not only increases the weight of the equipment, but also occupies the internal space, and also increases the Product Cost. For swimming pool cleaning robots, fish pond cleaning robots, etc., an additional motor suction cleaning system needs to be installed for cleaning operations, and the operating efficiency of the equipment is low.

To this end, embodiments of the present application provide a driving device and pool cleaning equipment, so that the structure of the driving device is simple.

Referring to Figure 1, an embodiment of the present application provides a pool cleaning device 1000, which can clean sediments, floating objects (such as fallen leaves, dead insects, etc.) and settled debris (such as sand and gravel, etc.) attached to the wall of the pool. At least one of the debris must be cleaned. Pools can include swimming pools, fish ponds, etc.

Referring to FIG. 1 , the pool cleaning equipment 1000 includes a driving device 100 and a body 200 . The driving device 100 is connected to the fuselage 200 . The driving device 100 is used to drive the body 200 to move back and forth in the pool and perform cleaning operations according to actual needs.

Referring to FIG. 1 , in some embodiments, the body 200 includes a main body 201 and support wheels 202 . The driving device 100 and the supporting wheel 202 are both connected to the main body 201 .

Referring to FIGS. 1 and 2 , in some embodiments, the driving device 100 includes a liquid flow channel 10 , a fluid driving mechanism 20 and a flow adjustment mechanism 30 . The liquid flow channel 10 includes a liquid supply flow channel 11 , a first liquid outlet flow channel 12 and a second liquid outlet flow channel 13 . Both the first liquid outlet channel 12 and the second liquid outlet channel 13 can communicate with the liquid supply channel 11 . The fluid driving mechanism 20 is used to drive fluid to flow in the liquid channel 10 . The flow adjustment mechanism 30 is used to distribute the flow rate of the fluid flowing out of the liquid supply channel 11 between the first liquid outlet channel 12 and the second liquid outlet channel 13 . The flow adjustment mechanism 30 is used to adjust the flow rate difference between the flow rate of the first liquid outlet channel 12 and the flow rate of the second liquid outlet channel 13 to control the movement of the pool cleaning equipment 1000 .

In the driving device 100 of the above embodiment, when the first liquid outlet channel 12 discharges liquid, it generates a first recoil driving force; when the second liquid outlet channel 13 discharges liquid, it generates a second recoil driving force, which is adjusted by the flow adjustment mechanism 30 The flow rate difference between the flow rate of the first liquid outlet channel 12 and the flow rate of the second liquid outlet channel 13 controls the resultant force of the first recoil driving force and the second recoil driving force, thereby controlling the movement of the pool cleaning device 1000 to the target area. The driving device 100 can use water flow to drive the swimming pool cleaning equipment 1000 to move, without the need to set up two independent motor systems to drive the swimming pool cleaning equipment 1000 to move and clean operations respectively. It has a simple structure, low cost, low power consumption, energy saving and environmental protection, and the equipment The high operating efficiency expands the application of the pool cleaning equipment 1000.

For example, when the resultant force of the first recoil driving force and the second recoil driving force is zero, the pool cleaning device 1000 is stationary. When the resultant force of the first recoil driving force and the second recoil driving force is non-zero, the pool cleaning device 1000 can be caused to walk to the target area to perform cleaning operations.

In some embodiments, the flow adjustment mechanism 30 is adjusted to adjust the flow difference and control the working power of the fluid driving mechanism 20, thereby controlling the movement of the pool cleaning device 1000.

For example, when the pool cleaning device 1000 is in the cleaning working mode, the fluid driving mechanism 20 is controlled to work with a larger working power (such as a first preset working power). The water flow sucked into the liquid supply channel 11 increases correspondingly as the working power of the fluid driving mechanism 20 increases, and the water flow discharged from the first liquid outlet channel 12 and/or the second liquid outlet channel 13 also increases accordingly. At this time, the position of the flow adjustment mechanism 30 can be adjusted so that the water flow discharged from the first liquid outlet flow channel 12 and the water flow discharged from the second liquid outlet flow channel 13 are both larger, and the water flow discharged from the first liquid outlet flow channel 12 The flow rate difference between the water flow and the water flow discharged from the second liquid outlet flow channel 13 is the first preset flow rate difference (the flow rate difference between the two is small at this time), so that the pool cleaning equipment 1000 can be used with a smaller flow rate. Speed walking enables the whole machine to clean in slow forward motion, with good cleaning effect, which improves the cleaning efficiency of the pool cleaning equipment 1000. In the cleaning working mode, the flow rate adjustment mechanism 30 can also be used to control the flow difference between the water flow discharged from the first liquid outlet channel 12 and the water flow discharged from the second liquid outlet channel 13 to be zero. At this time, the pool cleaning equipment 1000 can stop at the target area for cleaning, which is conducive to better cleaning in the target area.

For example, when the pool cleaning equipment 1000 is in the walking working mode, the demand for cleaning is small at this time. The fluid driving mechanism 20 is controlled to work with a smaller working power (such as a second preset working power, the second preset working power is smaller than the first preset working power). At this time, the position of the flow adjustment mechanism 30 can be adjusted so that the water flow discharged from the first liquid outlet channel 12 and the water flow discharged from the second liquid outlet channel 13 are both the second preset flow rate difference (at this time, the difference between the two is the second preset flow rate difference). (the second preset flow rate difference is greater than the first preset flow rate difference), for example, one of the first liquid outlet flow channel 12 and the second liquid outlet flow channel 13 is completely different from the liquid supply flow channel. 11 is connected, allowing the pool cleaning equipment 1000 to move quickly, reducing the power consumption of the fluid driving mechanism 20, and improving the operating efficiency of the equipment.

The pool cleaning equipment 1000 of the above embodiment can push water to flow in the liquid channel 10 through the fluid driving mechanism 20, and the underwater thrust generated by the flow adjustment mechanism 30 can achieve cleaning and walking with less propulsion system, and effectively Reduce the power consumption of the entire machine, thereby improving work efficiency and reducing hardware costs. In addition, the working power and underwater walking speed of the fluid driving mechanism 20 can be set respectively according to actual needs to adjust the walking of the pool cleaning equipment 1000, which is easy to adjust, has strong operability and strong practicability. When the working power of the fluid driving mechanism 20 is constant, the walking speed and/or direction of the pool cleaning device 1000 can be adjusted by adjusting the flow adjustment mechanism 30 .

In some embodiments, the flow adjustment mechanism 30 is used to adjust the flow rate difference between the flow rate of the first liquid outlet channel 12 and the flow rate of the second liquid outlet channel 13, thereby controlling the pool cleaning device 1000 to move in the first direction and / Or turning, so that the pool cleaning equipment 1000 can flexibly walk to the target area to perform cleaning operations.

It can be understood that the first direction may be a forward direction or a left-right direction of the pool cleaning device 1000 .

In some embodiments, when the flow rate difference between the flow rate of the first liquid outlet flow channel 12 and the flow rate of the second liquid outlet flow channel 13 is zero, the pool cleaning device 1000 is stationary in the first direction.

In some embodiments, when the flow rate difference between the flow rate of the first liquid outlet flow channel 12 and the flow rate of the second liquid outlet flow channel 13 is non-zero, the pool cleaning device 1000 moves and/or turns along the first direction.

In some embodiments, when the flow rate difference between the flow rate of the first liquid outlet flow channel 12 and the flow rate of the second liquid outlet flow channel 13 is greater than zero, the pool cleaning device 1000 moves in the positive direction of the first direction and/or Steering.

In some embodiments, when the flow rate difference between the flow rate of the first liquid outlet channel 12 and the flow rate of the second liquid outlet channel 13 is less than zero, the pool cleaning device 1000 moves in the negative direction of the first direction and/or Steering.

Illustratively, the flow adjustment mechanism 30 is used to adjust the flow rate difference between the flow rate of the first liquid outlet channel 12 and the flow rate of the second liquid outlet channel 13, thereby controlling the pool cleaning device 1000 to move in the first direction. The positive direction of the first direction is shown as the +X direction in Figure 3. The negative direction of the first direction is shown as the -X direction in Figure 3.

Please refer to FIGS. 3 to 5 . In some embodiments, when the fluid driving mechanism 20 is activated, the water flow ejected from the first liquid outlet channel 12 generates a first recoil driving force F1 , and the water flow from the second liquid outlet flow channel 12 generates a first recoil driving force F1 . The water jetted in the channel 13 generates the second recoil driving force F2. The ejected water flow is used to generate corresponding recoil driving force, thereby adjusting the walking direction along the first direction and changing the walking trajectory.

Referring to FIG. 3 , for example, the liquid outlet of the first liquid outlet channel 12 and the liquid outlet of the second liquid outlet channel 13 are in opposite directions. The axial centerline of the first liquid outlet channel 12 and the axial centerline of the second liquid outlet channel 13 all coincide with the first direction. At this time, adjusting the working power of the flow adjustment mechanism 30 and controlling the fluid driving mechanism 20 can adjust the walking direction of the pool cleaning equipment 1000 to form a straight walking track.

Please refer to Figures 4, 5 and 6. As another example, the liquid outlet of the first liquid outlet channel 12 and the liquid outlet of the second liquid outlet channel 13 are in opposite directions. The axial centerline of the first liquid outlet channel 12 forms an angle greater than zero with the first direction (shown as the S0 direction in FIG. 6 ), and the axial centerline of the second liquid outlet channel 13 forms an angle with the first direction (shown as the S0 direction in FIG. 6 ). form an included angle greater than zero. Universal wheels or driving wheels are provided on the fuselage 200 . The pool cleaning device 1000 is driven forward by an additional motor or an additional fluid jet propulsion system. The water flow sprayed through the first liquid outlet flow channel 12 and the water flow sprayed from the second liquid outlet flow channel 13 exert a force in the deflection direction on the pool cleaning device 1000, so that the pool cleaning device 1000 turns to form a curved walking track, thereby making the pool The cleaning equipment 1000 can flexibly turn to the target area when cleaning the pool to prevent the area to be cleaned from being missed or missed.

Illustratively, the flow adjustment mechanism 30 is used to adjust the flow rate difference between the flow rate of the first liquid outlet channel 12 and the flow rate of the second liquid outlet channel 13, thereby controlling the pool cleaning device 1000 to move in the first direction. The first direction is the actual walking direction of the pool cleaning equipment 1000, as shown in the S0 direction of Figure 6 or Figure 7 .

In some embodiments, the flow adjustment mechanism 30 is used to adjust the flow rate difference between the flow rate of the first liquid outlet channel 12 and the flow rate of the second liquid outlet channel 13, thereby controlling the pool cleaning device 1000 to turn in the first direction. The first direction is the left and right direction of the pool cleaning device 1000 .

Please refer to FIGS. 7 and 8 . As another example, both the first liquid outlet channel 12 and the second liquid outlet channel 13 can rotate relative to the fuselage 200 . For example, a rotation mechanism 40 can be added to drive the first liquid outlet channel 12 and the second liquid outlet channel 13 to rotate. By controlling the rotation of the first liquid outlet channel 12 and/or the rotation of the second liquid outlet channel 13, the pool cleaning device 1000 forms a curved walking trajectory, thereby allowing the pool cleaning device 1000 to flexibly turn to the direction when cleaning the pool. Target area to prevent the area to be cleaned from being missed or missed. For example, the liquid outlet of the first liquid outlet channel 12 and the liquid outlet of the second liquid outlet channel 13 face opposite directions. It can be understood that the axial centerline of the first liquid outlet channel 12 can coincide with the axial centerline of the second liquid outlet channel 13 , or they can be parallel, or they can form an included angle greater than zero, as long as they can pass through the flow adjustment mechanism 30 Just adjust the flow rate difference between the flow rate of the first liquid outlet channel 12 and the flow rate of the second liquid outlet channel 13 to control the movement and/or steering of the pool cleaning equipment 1000. For example, the axis center line of the first liquid outlet flow channel 12 can coincide with the axis center line of the second liquid outlet flow channel 13, which simplifies processing and can more conveniently control the walking trajectory of the pool cleaning device 1000.

Referring to FIG. 8 , by way of example, the rotating mechanism 40 includes a rotating motor 41 , a gear 42 , a ring gear 43 and a rotating platform 44 . The first liquid outlet channel 12 and the second liquid outlet channel 13 are provided on the rotating platform 44 . The rotating motor 41 drives the rotating platform 44 to rotate through the gear 42 and the ring gear 43, and then drives the first liquid outlet channel 12 and the second liquid outlet channel 13 on the rotating platform 44 to rotate.

Referring to FIGS. 9 to 11 , in some embodiments, the fluid driving mechanism 20 includes a driving motor 21 and an impeller assembly 22 . The driving motor 21 is provided in the liquid supply channel 11 . The impeller assembly 22 is connected to the drive motor 21 . The impeller assembly 22 is disposed in the liquid supply flow channel 11 . When the driving motor 21 is started, the impeller assembly 22 connected to the driving motor 21 causes the water and debris in the pool to be sucked into the liquid supply channel 11 through the liquid inlet (not labeled) of the liquid supply channel 11 .

Illustratively, the drive motor 21 includes an outer rotor motor. The impeller assembly 22 is connected to the outer rotor of the outer rotor motor. The external rotor motor is driven by external rotation, and the rotational torque of the external rotor motor is significantly increased, thereby being able to drive the larger-sized impeller assembly 22 to rotate, significantly improving cleaning efficiency; on the premise of ensuring cleaning performance, the external rotor motor has low power consumption. , extending the working time of the external rotor motor. The impeller assembly 22 is wrapped around the outer side of the outer rotor of the outer rotor motor. The impeller assembly 22 is integrated with the appearance of the outer rotor motor and is compact in size.

For example, the impeller assembly 22 is detachably connected to the outer rotor motor, which facilitates disassembly, assembly and maintenance of the outer rotor motor. For example, the impeller assembly 22 is threadedly connected to the outer rotor of the outer rotor motor. Illustratively, the top of the impeller assembly 22 has a built-in nut, and the top of the outer rotor motor is provided with threads that match the nut. The impeller assembly 22 is rotated and tightened to the outer rotor motor, which facilitates the assembly of the impeller assembly 22 and/or the outer rotor motor. Quickly remove and replace after damage.

In other embodiments, the impeller assembly 22 can also be fixedly connected to the outer rotor of the outer rotor motor through screws.

In other embodiments, the driving motor 21 may also include an inner-rotor motor.

In other embodiments, the driving motor 21 may be replaced by a driving component such as a water pump.

Referring to FIGS. 9 and 10 , in some embodiments, the liquid supply channel 11 includes a water tank 111 and a liquid guide channel 112 . The liquid guide flow channel 112 is connected with the water tank 111. The fluid driving mechanism 20 is located in the liquid guide flow channel 112. Both the first liquid outlet flow channel 12 and the second liquid outlet flow channel 13 can be connected with the liquid guide flow channel 112. The liquid inlet of the liquid supply channel 11 is provided on the water tank 111 . The liquid outlet of the liquid supply channel 11 is the liquid outlet 1122 of the liquid guide channel 112 . The liquid outlet of the water tank 111 is connected with the liquid inlet 1121 of the liquid guide channel 112 .

For example, the liquid inlet of the liquid supply channel 11 is provided at the bottom of the water tank 111 .

Referring to FIGS. 9 and 10 , in some embodiments, the liquid guide channel 112 includes a fixed base 51 and a rectifying member 52 . The driving motor 21 is installed on the fixed base 51 . The rectifying member 52 is connected to the fixed seat 51 , and the rectifying member 52 is located behind the impeller assembly 22 in the direction of liquid flow. For example, the impeller assembly 22 and the rectifying member 52 are arranged sequentially along the liquid flow direction. The rectifying member 52 is used to rectify the liquid flowing through the liquid guide channel 112 so that the liquid rotates in the opposite direction to the rotation direction of the impeller assembly 22 .

For example, the impeller assembly 22 and the rectifying member 52 are arranged in sequence along the liquid flow direction in the liquid guide channel 112 . The rectifier 52 can absorb the wake vortex energy of the impeller assembly 22 and improve the working efficiency of the impeller assembly 22 and the drive motor 21 .

For example, the flow direction of the liquid after flowing through the rectifier 52 is substantially linear.

Please refer to Figure 12(a) and Figure 12(b). In some embodiments, the liquid inlet 1121 and the liquid outlet 1122 of the liquid guide flow channel 112 are arranged non-facingly so that the liquid guide flow channel 112 is a meandering flow. road. Compared with the driving structure in which the liquid inlet and the liquid outlet of the flow channel are directly opposite to each other, in the driving device 100 of this embodiment, the liquid inlet 1121 and the liquid outlet 1122 of the liquid guide flow channel 112 are not arranged oppositely, so that The liquid guide channel 112 is a curved channel. In this way, the size of the liquid supply channel 11 along the axial direction of the fluid driving mechanism 20 can be reduced, thereby reducing the height of the pool cleaning equipment 1000. The structure is reasonable, compact and beneficial to Achieve miniaturization.

Please refer to FIGS. 3 and 4 . In some embodiments, the liquid inlet 1121 of the liquid guide channel 112 is provided on the side of the fixed seat 51 , and the liquid outlet 1122 of the liquid guide channel 112 is provided on the rectifier 52 . In this way, the overall structure of the driving device 100 is compact and reasonable, which is conducive to the miniaturization design of the product; and the liquid flowing out from the impeller assembly 22 can be rectified by the rectifier 52 and then discharged from the liquid outlet 1122 of the liquid guide channel 112 .

Referring to FIG. 12(a) and FIG. 12(b) , illustratively, the rectifying member 52 includes a hollow shell 521 , an intermediate portion 522 and a rectifying blade 523 . At least part of the middle portion 522 is provided in the hollow shell 521 . The middle part 522 is spaced apart from the hollow shell 521 . One end of the rectifying blade 523 is connected to the outer periphery of the intermediate portion 522 . The other end of the rectifying blade 523 is connected to the inner wall of the hollow shell 521 .

The number of rectifying blades 523 can be designed according to actual requirements, such as two, three, four, five, six, seven, eight or more, which are not limited here. Exemplarily, a plurality of array blades are distributed along the circumference.

Referring to Figure 12(c) and Figure 12(d), in some embodiments, the rectifying blade 523 has a first side 5231 and a second side 5232 arranged oppositely along the liquid flow direction. The projections of the first side 5231 and the second side 5232 on the cross section of the hollow shell 521 are spaced apart to ensure that the rectifier 52 can cause the liquid flowing out of the impeller assembly 22 to rotate in the opposite direction of the rotation direction of the impeller assembly 22 to achieve rectification. Effect. Exemplarily, the second side 5232 and the first side 5231 are arranged sequentially along the liquid flow direction.

It can be understood that the relative positions of the projections of the first side 5231 and the second side 5232 on the cross-section of the hollow shell 521 are determined according to the rotation direction of the impeller assembly 22 or the rotation direction of the blades of the impeller assembly 22 . For example, if the rotation direction of the impeller assembly 22 or the rotation direction of the blades of the impeller assembly 22 is counterclockwise, then the projection of the first side 5231 on the cross section of the hollow shell 521 deviates from the second side 5232 in the clockwise direction. The projections on the cross-section of the hollow shell 521 are preset separation distances.
