Description

Technical Field

[0001] The invention belongs to the technical field of unmanned pool cleaning, and in particular relates to a pool cleaning robot. Background Art

[0002] The stain cleaning area in the mirror fountain pool is large and the size is huge. The fountain structure cannot bear the pressure of manual cleaning operations for a long time. Each cleaning operation requires draining the water resources in the pool before cleaning, which consumes a lot of manpower, takes a long time and has low efficiency.

[0003] Therefore, a pool cleaning robot is provided to replace manual labor to complete corresponding work, reduce cleaning costs and improve cleaning efficiency. Summary of the invention

[0004] In view of the problems in the prior art that manual cleaning is inefficient, time-consuming, and easily causes damage to the pool bottom, the purpose of the present invention is to provide a pool cleaning robot that replaces manual cleaning to clean the pool.

[0005] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows:

[0006] A pool cleaning robot comprises a frame, wherein the frame is provided with a power source, a walking mechanism, a water suction motor, a filter bag, and a roller brush;

[0007] The power source is electrically connected to the walking mechanism, the water suction motor, and the roller brush, and provides electrical energy;

[0008] The frame is provided with a motor compartment for placing a water suction motor and a filter compartment for placing a filter bag, the motor compartment and the filter compartment are connected, the lower end of the filter compartment is opened from the bottom surface of the frame, the frame also includes a hatch for closing the upper end of the filter compartment, the motor compartment is connected to the outside, and the roller brush is arranged on the bottom surface of the frame and has a rotational power;

[0009] The upper end of the filter pocket is completely open, and the inner bottom surface of the filter pocket is provided with a slag inlet nozzle which is larger on the outside and smaller on the inside. The slag inlet nozzle is provided with a slag channel with an isosceles trapezoidal cross-sectional shape, the large end of the slag channel is provided with a first extension nozzle, and the small end of the slag channel is provided with a second extension nozzle.

[0010] The present invention adopts a walking mechanism to drive the frame to walk along a certain route at the bottom of the pool. During the movement of the frame, the roller brush scrubs the pool bottom by rotating itself, so that the dirt adhering to the pool surface is separated. When the dirt is separated, the water suction motor continues to rotate to generate suction. Since the motor cabin and the filter cabin are connected, the lower end of the filter cabin opens from the bottom surface of the frame, and the suction generated by the water suction motor is transmitted to the bottom surface of the frame. Under the action of the suction, the separated dirt enters the filter bag through the slag inlet nozzle, and the sucked water enters the motor cabin through the filter bag, flows out from the upper end of the motor cabin connected to the outside world, and returns to the pool. Due to the interception effect of the filter bag, the dirt continues to stay in the filter bag.

[0011] In order to facilitate the entry of dirt into the filter bag and prevent the dirt in the filter bag from flowing back, the present invention specifically limits the shape of the slag inlet nozzle to be large on the outside and small on the inside. The design of large on the outside and small on the inside has the following advantages. The isosceles trapezoidal slag channel forms a structural feature of large on the outside and small on the inside. When water is taken in, the water and dirt can flow in easily due to the large opening on the outside, and the large opening has a larger inflow range. The small opening on the inside can prevent the dirt that has entered the inside from flowing back.

[0012] The present invention drives the frame to move along a certain route at the bottom of the pool through a walking mechanism. During the walking process, the roller brush scrubs the pool bottom through its own rotation, and the dirt brushed off flows into the filter bag under the suction force of the water suction motor to be collected centrally. Therefore, the pool cleaning robot provided by the present invention can replace manual labor to effectively clean the pool by penetrating underwater, and can avoid the situation where manual cleaning requires the overall replacement of water resources in the pool, thereby effectively saving water resources. In addition, compared with manual labor, the pool cleaning robot is more compact and lightweight, and is suitable for a variety of operating occasions.

[0013] Beneficial effects of the present invention:

[0014] 1. The present invention drives the frame to walk along a certain route at the bottom of the pool through a walking mechanism. During the walking process, the roller brush scrubs the pool bottom through its own rotation. The dirt brushed off flows into the filter bag under the suction of the water suction motor to achieve centralized collection. Therefore, the pool cleaning robot provided by the present invention can replace manual labor to effectively clean the pool by penetrating into the water, and can avoid the situation where manual cleaning requires the overall replacement of water resources in the pool, thereby effectively saving water resources. In addition, the pool cleaning robot is more compact and lightweight than manual labor, and is suitable for a variety of operating occasions.

[0015] 2. It adopts wireless transmission for control, without cables, and is convenient for use in long-distance and large-scale cleaning occasions. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The technical solution of the present invention is described in detail below in conjunction with specific embodiments and their accompanying drawings. The embodiments recorded herein are specific embodiments of the present invention, which are used to illustrate the concept of the present invention; these descriptions are explanatory and exemplary and should not be construed as limitations on the embodiments of the present invention and the scope of protection of the present invention. In addition to the embodiments recorded herein, those skilled in the art can also adopt other obvious technical solutions based on the contents disclosed in the claims of this application and its specification, including technical solutions that adopt any obvious replacements and modifications to the embodiments recorded herein.

[0034] Example 1

[0035] like Figure 1 , 2 As shown in , 4, and 6, this embodiment provides a pool cleaning robot, including a frame 1, on which a power source 82, a walking mechanism 84, 2, 3, a water suction motor 88, a filter bag 7, and a roller brush are installed;

[0036] The power source 82 is electrically connected to the walking mechanism 84, 2, 3, the water suction motor 88, and the roller brush, and provides electrical energy;

[0037] The frame 1 is provided with a motor compartment 12 for placing the water suction motor 88, and a filter compartment 11 for placing the filter bag 7. The motor compartment 12 is connected to the filter compartment 11, and the lower end of the filter compartment 11 is opened from the bottom surface of the frame 1. The frame 1 also includes a hatch 5 for closing the upper end of the filter compartment 11. The motor compartment 12 is connected to the outside. The roller brush is arranged on the bottom surface of the frame 1 and has a rotating power.

[0038] The upper end of the filter bag 7 is completely open, and a slag inlet nozzle 71 which is larger on the outside and smaller on the inside is provided on the inner bottom surface of the filter bag 7. The slag inlet nozzle 71 is provided with a slag channel 711 with an isosceles trapezoidal cross-sectional shape. The large end of the slag channel 711 is provided with a first extension nozzle 712, and the small end of the slag channel 711 is provided with a second extension nozzle 713.

[0039] In this embodiment, the present invention uses walking mechanisms 84, 2, 3 to drive the frame 1 to walk along a certain route at the bottom of the pool. During the movement of the frame 1, the roller brush scrubs the pool bottom by rotating itself to separate the dirt adhering to the pool surface. When the dirt is separated, the water suction motor 88 continues to rotate to generate suction. Since the motor compartment 12 and the filter compartment 11 are connected, the lower end of the filter compartment 11 opens from the bottom surface of the frame 1. The suction generated by the water suction motor 88 is transmitted to the bottom surface of the frame 1. Under the action of the suction, the separated dirt enters the filter bag 7 through the slag inlet 71. The sucked water enters the motor compartment 12 through the filter bag 7, flows out from the upper end of the motor compartment 12 connected to the outside world, and returns to the pool. Due to the interception effect of the filter bag 7, the dirt continues to stay in the filter bag 7.

[0040] In order to facilitate the entry of dirt into the filter bag 7 and prevent the dirt in the filter bag 7 from flowing back, the present invention specifically limits the shape of the slag inlet nozzle 71 to be large on the outside and small on the inside. The design of large on the outside and small on the inside has the following advantages. The isosceles trapezoidal slag channel 711 forms a structural feature of large on the outside and small on the inside. When water is taken in, the water and dirt can flow in easily due to the large opening on the outside, and the large opening has a larger inflow range. The small opening on the inside can prevent the dirt that has entered the inside from flowing back.

[0041] The present invention drives the frame 1 to move along a certain route at the bottom of the pool through the walking mechanism 84, 2, 3. During the walking process, the roller brush scrubs the pool bottom through its own rotation, and the dirt brushed off flows into the filter bag 7 under the suction of the water suction motor to be collected centrally. Therefore, the pool cleaning robot provided by the present invention can replace manual labor to effectively clean the pool by penetrating underwater, and can avoid the situation where manual cleaning requires the overall replacement of water resources in the pool, thereby effectively saving water resources. In addition, the pool cleaning robot is more compact and lightweight than manual labor, and is suitable for a variety of operating occasions.

[0042] Example 2

[0043] like Figure 1 As shown, this embodiment provides a pool cleaning robot, which is different from the embodiment 1 in that the walking mechanism 84, 2, 3 is specifically limited to include a walking motor 84, a driving wheel 2 and a crawler 3, the walking motor 84 is installed through the frame 1, the driving wheel 2 is connected to the output end of the walking motor 84, and the crawler 3 cooperates with the driving wheel 2;

[0044] There are four travel motors 84, which are distributed at the four corners of the frame 1 in a square shape. Each travel motor 84 is independently connected to a driving wheel 2, and the driving wheels 2 on the same side cooperate with a crawler belt 3.

[0045] The outer surface of the crawler 3 is provided with striped protrusions for increasing friction.

[0046] In this embodiment, the walking motor 84 drives the driving wheel 2 to rotate, and the driving wheel 2 cooperates with the track 3 to drive the track 3 to move. The striped protrusions on the outer surface of the track 3 can effectively increase the friction with the bottom of the pool to avoid slipping, thereby improving the walking ability and climbing ability of the pool cleaning robot, so that the pool cleaning robot can adapt to some pools with steps.

[0047] Example 3

[0048] like Figure 2 As shown, this embodiment provides a pool cleaning robot, which is different from the embodiment 1 in that the frame 1 is provided with a handle 6 for holding.

[0049] In this embodiment, the handle 6 is mainly used to facilitate the staff to drag the pool cleaning robot out of the pool and to use it for daily transportation.

[0050] Example 4

[0051] like Figure 2 , 3 As shown, this embodiment provides a pool cleaning robot, which differs from Embodiment 1 in that the frame 1 is connected to a hatch filter structure 13 composed of a filter 131 and a grille 132 at the hatch of the motor compartment 12, with the grille 132 on the outside and the filter 131 on the inside.

[0052] In the present embodiment, since the water suction motor 88 will discharge the sucked pool water through the hatch of the motor compartment 12, in order to prevent the hatch from being blocked by debris in the pool and to prevent debris from entering the motor compartment 12 and causing the rotor of the water suction motor 88 to be entangled by debris, a hatch filtering structure 13 is provided, with the grille 132 on the outside to block larger and slender debris, and the filter screen 131 on the inside to provide secondary blocking for some smaller debris.

[0053] Example 5

[0054] like Figure 4 , 5 As shown, this embodiment provides a pool cleaning robot, which differs from Embodiment 1 in that the filter bag 7 is provided with a skeleton 72 and filter layers 731, 732 located between the skeleton 72, the filter layers 731, 732 include a first filter net 731 located on the outside and a second filter net 732 located on the inside, and the mesh number of the first filter net 731 is smaller than that of the second filter net 732.

[0055] In this embodiment, the skeleton 72 is mainly used to determine the shape of the filter pocket 7. Because the pool water must first come into contact with the second filter screen 732, the second filter screen 732 with a larger mesh size in the filter layers 731, 732 is arranged on the inner side, so as to filter larger dirt and debris first, and the first filter screen 731 with a smaller mesh size is on the outer side to filter smaller dirt and debris.

[0061] In this embodiment, the lithium battery pack has the advantages of low self-discharge rate, high energy density, light weight, compactness and environmental protection.

[0062] Example 8

[0063] like Figure 7 As shown, this embodiment provides a pool cleaning robot, which is different from the embodiment 1 in that it also includes a controller 81, a power source 82 connected to the controller 81, and the controller 81 is connected to a power conversion unit 85, a walking mechanism 84, 2, 3, a water suction motor 88, a position sensor 83, a wireless signal transceiver 86, and an expansion interface 87;

[0064] The power conversion unit 85 outputs the electrical energy required by the walking mechanism 84 , 2 , 3 , the water suction motor 88 , the position sensor 83 and the wireless signal transceiver 86 .

[0065] In this embodiment, the controller 81 acts as an information processor to process various control information of the pool cleaning robot. The power source 82 transmits electric energy to the controller 81, and the controller 81 transmits the electric energy to the power conversion unit 85, which converts the electric energy into a suitable power size for use by the walking mechanism 84, 2, 3, the water suction motor 88, the position sensor 83, and the wireless signal transceiver 86;

[0066] The expansion interface 87 is used to reserve interface points for adding additional components later;

[0067] The position sensor 83 is used to detect the current position of the pool cleaning robot and determine whether there are any obstacles in front, behind, left, or right;

[0068] The wireless signal transceiver 86 is used to feed back various control information to the user end, and is also used to receive instructions fed back by the user end. The pool cleaning robot can choose two moving modes to clean the pool. The first is that the user end can control the pool cleaning robot to move freely.
