[0021] like Figures 1 to 4 As shown, this application provides a water surface cleaning device, which includes a housing 1, a roller brush assembly 2, a storage frame 3, and an anti-backflow component 4. The housing 1 has an internal cavity 11, which extends along the length of the housing 1 and has a first opening 12. The roller brush assembly 2 is disposed at the first opening 12 of the storage cavity 11 and can rotate to carry debris in the pool into the storage cavity 11. The storage frame 3 is slidably disposed in the storage cavity 11 and can reciprocate along the length of the housing 1 to be housed in or separated from the storage cavity 11. The storage frame 3 is used to collect debris that enters the storage cavity 11. The anti-backflow component 4 is disposed in the storage frame 3 and is located on the side of the roller brush assembly 2 away from the first opening 12. The anti-backflow component 4 is used to prevent debris in the storage frame 3 from overflowing.

[0022] This application provides a receiving cavity 11 inside the housing 1, which extends through the length of the housing 1. By sliding the storage frame 3 to the receiving cavity 11, the storage frame 3 can be placed or removed from the receiving cavity 11 by sliding it back and forth along the length of the housing 1. This allows for convenient and quick removal of the storage frame 3, is simple to operate, and improves the efficiency of cleaning up debris and garbage.

[0023] Specifically, the accommodating cavity 11 extends downward from the middle of the housing 1 to the bottom of the housing 1.

[0024] refer to Figures 1 to 5The storage frame 3 includes a frame body 31, a handle 32, a baffle 33, a first buckle part 34, and a third side plate 314. The frame body 31 includes a base plate 311, a first side plate 312, and a second side plate 313. The first side plate 312, the second side plate 313, and the third side plate 314 are all disposed on the base plate 311. The first side plate 312 and the second side plate 313 are respectively disposed on opposite sides of the base plate 311. The third side plate 314 is disposed between the first side plate 312 and the second side plate 313. The third side plate 314 is detachably connected to the base plate 311.

[0025] The two ends of the baffle 33 are respectively connected to the first side plate 312 and the second side plate 313. The handle 32 and the first buckle part 34 are both located on the side of the baffle 33 away from the first opening 12. The handle 32 has a groove 321. The first buckle part 34 is located above the groove 321. There is a gap between the first buckle part 34 and the groove 321 to provide space for the first buckle part 34 to elastically deform. The handle 32 passes through the third side plate 314 and protrudes outside the housing 1, making it convenient for the user to pull out the storage frame 3.

[0026] refer to Figure 6 The housing 1 has a snap-fit ​​hole 13, and the first snap-fit ​​part 34 is elastic, capable of elastic deformation in the height direction of the housing 1, so that the first snap-fit ​​part 34 abuts against or separates from the snap-fit ​​hole 13, thereby fixing or releasing the storage frame 3 relative to the housing 1. By providing the first snap-fit ​​part 34 and the snap-fit ​​hole 13, the stability of the storage frame 3 during operation can be improved, preventing the storage frame 3 from falling off.

[0027] Specifically, the snap-fit ​​hole 13 is located on the top wall of the accommodating cavity 11.

[0028] Specifically, press down on the first latch 34 to bend it downwards. After the first latch 34 disengages from the latch hole 13, it returns to its original state. Then, pull the handle 32 to slide it away from the first opening 12 until the storage frame 3 separates from the receiving cavity 11. After that, the debris and garbage in the storage frame 3 can be cleaned.

[0029] refer to Figure 5 and Figure 7 The storage frame 3 also includes a second buckle 35, and the frame body 31 also includes a pivot 315. The pivot 315 is connected to the base plate 311. One side of the third side plate 314 is rotatably connected to the pivot 315, and the other side of the third side plate 314 is connected to the second buckle 35. The second buckle 35 is elastic and can undergo elastic deformation in the height direction of the housing 1 so that the second buckle 35 abuts against or separates from the side of the baffle 33 near the first opening 12, thereby fixing the third side plate 314 to the base plate 311 or releasing it from the base plate 311.

[0030] Specifically, the rotating shaft 315 is inserted into the end of the base plate 311 away from the anti-backflow component 4, and both ends of the rotating shaft 315 protrude outside the base plate 311. The two ends of the third side plate 314 on the same side are respectively sleeved on the two ends of the rotating shaft 315, and the two ends of the third side plate 314 are respectively provided with semi-circular openings 316. When the third side plate 314 is released from the housing 1, the third side plate 314 and the base plate 311 are movably connected, and the third side plate 314 can rotate around the rotating shaft 315, thereby separating the third side plate 314 from the rotating shaft 315 through the semi-circular openings 316. Therefore, the setting of the semi-circular openings 316 makes it easy for the third side plate 314 to be directly pulled out and separated from the rotating shaft 315.

[0031] In this embodiment, there are two second latching parts 35, which are spaced apart on the upper part of the third side plate 314.

[0032] refer to Figure 4 , Figure 6 and Figure 8 The storage frame 3 also includes sliders 14, with at least two sliders 14 respectively disposed on the first side plate 312 and the second side plate 313. Slide rails 15 are respectively provided on the two opposite inner side walls of the accommodating cavity 11. The sliders 14 are slidably connected to the slide rails 15 to drive the storage frame 3 to move along the length of the housing 1. By slidably connecting the sliders 14 to the slide rails 15 and pushing the handle 32 towards the first opening 12, the first latching part 34 bends downward under the action of the top wall of the accommodating cavity 11 and the pushing force applied by the user, until the first latching part 34 engages with the latching hole 13. The first latching part 34 then returns to its original shape, thus achieving the assembly of the storage frame 3 and the accommodating cavity 11.

[0033] refer to Figure 14 The water surface cleaning device also includes a storage expansion device 5, which includes a storage body 51 and a connecting component 52. The storage body 51 is connected to one side of the connecting component 52, and the other side of the connecting component 52 is detachably connected to the frame body 31. When the third side plate 314 is separated from the bottom plate 311, the storage expansion device 5 is configured to be connected to the frame body 31.

[0034] Specifically, the storage expansion device 5 can be a bag or a frame structure.

[0035] Specifically, the connecting component 52 includes a main frame 521, a third snap-fit ​​part 522, and a locking part 523. The main frame 521 has a ring-shaped structure. The third snap-fit ​​part 522 and the locking part 523 are located on the same side of the main frame 521. The third snap-fit ​​part 522 and the locking part 523 are respectively located on the top and bottom surfaces of the main frame 521. The third snap-fit ​​part 522 is elastic and is configured to snap-fit ​​with the baffle 33. The locking part 523 is configured to engage with the rotating shaft 315. The third snap-fit ​​part 522 and the locking part 523 cooperate to realize the connection between the storage expansion device 5 and the storage frame 3, thereby increasing the volume of miscellaneous items storage.

[0036] Furthermore, there are two of each of the third latching part 522 and the engaging part 523, with the engaging part 523 having a semi-circular opening 316 structure.

[0037] Specifically, the storage body 51 has a hollow structure to filter water.

[0038] For details, please refer to Figure 3 , Figure 6 and Figure 7 The first latching part 34, the second latching part 35, and the third latching part 522 have the same structure. Each of the three latching parts includes a connecting part 341 and a protrusion 342. The protrusion 342 protrudes from the top surface of the connecting part 341. The connecting part 341 of the first latching part 34 is connected to the baffle 33, and the protrusion 342 of the first latching part 34 is configured to insert into the latching hole 13 and abut against the inner sidewall of the latching hole 13. The connecting part 341 of the second latching part 35 is connected to the third side plate 314, and the protrusion 342 of the second latching part 35 is configured to abut against the side of the baffle 33 away from the first latching part 34. The connecting part 341 of the third latching part 522 is connected to the main frame 521, and the protrusion 342 of the third latching part 522 is configured to abut against the side of the baffle 33 away from the first latching part 34.

[0039] Furthermore, the protrusions 342 of the first latching portion 34, the second latching portion 35, and the third latching portion 522 have at least one inclined surface to reduce resistance during latching.

[0040] When the volume needs to be expanded, the storage frame 3 separates from the accommodating cavity 11, the second latch 35 is pressed down, causing the second latch 35 to bend downwards, and the third side plate 314 to rotate backwards around the pivot 315. Then, the third side plate 314 is pulled out upwards in an oblique direction, and the pivot 315 separates from the third side plate 314 from the semi-circular opening 316, completing the disassembly of the third side plate 314. Then, the engaging part 523 is engaged into the pivot 315, and the main frame 521 is rotated forward, so that the third latch 522 is engaged with the baffle 33, completing the assembly of the storage expansion device 5 and the storage frame 3.

[0041] When expansion is no longer needed, the storage expansion device 5 needs to be disassembled. The third latch 522 separates from the baffle 33, and the engaging part 523 separates from the rotating shaft 315, thus completing the disassembly of the storage expansion device 5. Then, the semi-circular opening 316 of the third side plate 314 is assembled with the rotating shaft 315. The third side plate 314 rotates forward around the rotating shaft 315, and then the second latch 35 is pushed to abut against the baffle 33, thus completing the assembly of the third side plate 314.

[0042] refer to Figure 3 and Figure 4 The storage frame 3 also includes a first float. The base plate 311 has multiple perforations. The storage frame 3 also includes a first cavity 36, which is disposed on the base plate 311. The first float is disposed within the first cavity 36. When the water surface cleaning device collects debris and garbage, the storage frame 3 becomes increasingly heavy, causing the device to sink. By providing the first cavity 36 and / or the first float, additional buoyancy can be provided, effectively offsetting some of the weight of the debris and preventing the device from sinking excessively.

[0043] For details, please refer to Figure 3 and Figure 5 The storage box 3 also includes a medicine box 37, which is set on the base plate 311 and spaced apart from the first cavity 36. The medicine box 37 is used to store medicines for water purification, disinfection, etc. in the pool.

[0044] Furthermore, the first side plate 312 and the second side plate 313 have a clearance notch 317 at the end away from the third side plate 314 to avoid the roller brush assembly 2. The bottom plate 311 is arranged in an upward arc shape at the end away from the third side plate 314.

[0045] refer to Figures 9 to 13 The anti-backflow component 4 is vertically mounted on the base plate 311, which has an insertion hole 318. The anti-backflow component 4 includes a main body 41, a fixing part 43, and a second float 42. The fixing part 43 is made of flexible material. One end of the fixing part 43 is connected to the bottom end of the main body 41, and the other end of the fixing part 43 is inserted into the insertion hole 318 to fix the anti-backflow component 4 relative to the storage frame. The top end of the main body 41 has a second cavity 411. The second cavity 411 is formed by bending the top end of the main body 41 downward to form a semi-circular structure. The second cavity 411 is arranged through the length of the main body 41. The second float 42 is disposed in the second cavity 411 and the second float 42 matches the second cavity 411.

[0046] In other embodiments, the fixing part 43 and the storage frame can also be fixed by means of adhesive bonding, other assembly structures, etc.

[0047] Specifically, the main body 41 is made of rigid material, while the flexible material can be soft rubber, silicone, rubber, or TPU.

[0048] Specifically, the main body 41 also includes a support portion 412, which is disposed on the side wall of the second cavity 411 and is used to support the second float 42. Furthermore, there are multiple support portions 412, which are spaced apart along the axial direction of the second cavity 411 on the side wall of the second cavity 411.

[0049] refer to Figure 10 The fixing part 43 includes a first flange part 431, a second flange part 432, and a connecting part 433. The first flange part 431 is disposed at the bottom end of the main body part 41, and the connecting part 433 is disposed between the first flange part 431 and the second flange part 432. The first flange part 431 and the second flange part 432 protrude relative to the connecting part 433. A channel 434 is formed between the first flange part 431, the connecting part 433, and the second flange part 432. The connecting part 433 is configured to be embedded in the socket 318. The end faces of the first flange part 431 and the second flange part 432 respectively abut and limit the corresponding port edge of the socket 318 to restrict the displacement of the fixing part 43 relative to the socket 318 in the vertical direction.

[0050] Specifically, the first flange portion 431 and the second flange portion 432 are respectively provided on opposite sides of the connecting portion 433 along the width direction of the fixing portion 43, so that grooves 434 are formed on opposite sides of the connecting portion 433 near or away from the third side plate 314.

[0051] Furthermore, the fixing part 43 also includes a first guide part 435, which is disposed at the bottom end of the second flange part 432. The first guide part 435 and the second flange part 432 are integrally disposed. The width of the first guide part 435 gradually decreases from the end connected to the second flange part 432 to the end away from the second flange part 432, so as to facilitate insertion into the insertion hole 318.

[0052] In this embodiment, the cross-section of the first flange portion 431 and the second flange portion 432 is rectangular, and the cross-section of the first guide portion 435 is trapezoidal.

[0053] refer to Figures 10 to 12 The fixing part 43 also includes a first extension part 436, one end of which is connected to the bottom end of the main body part 41, and the other end of which is connected to the first flange part 431. By providing the first extension part 436, the distance between the fixing part 43 and the main body part 41 is extended, thereby increasing the curvature of the main body part 41.

[0054] Specifically, the width of the connecting portion 433 is greater than the width of the first extension portion 436, and the widths of the first flange portion 431 and the second flange portion 432 are equal and greater than the width of the connecting portion 433.

[0055] The fixing part 43 further includes a second extension part 437, which is disposed at the bottom end of the first guide part 435. By providing the second extension part 437, it is convenient for the user to apply force to insert the connecting part 433 into the socket 318.

[0056] Specifically, the fixing part 43 is fixed to the bottom end of the main body part 41 by adhesive coating. In other embodiments, it can also be fixed by bonding, assembly or other methods.

[0057] There are multiple fixing parts 43 and multiple insertion holes 318. Multiple insertion holes 318 are arranged at intervals along the base plate 311, and multiple fixing parts 43 are arranged at intervals at the bottom end of the main body part 43.

[0058] The buoyancy of the second float is greater than or equal to the sum of the weights of the main body 41 and the fixed part 43.

[0059] When the water surface cleaning device starts working, water flows in through the first opening 12 and impacts the anti-backflow component 4. Due to the flexible nature of the fixing part 43, the anti-backflow component 4 tilts away from the first opening 12, facilitating the flow of water and debris into the storage frame 3. When the water surface cleaning device stops operating, the anti-backflow component 4 floats in the water under the action of the second float 42, that is, the anti-backflow component 4 returns to a roughly vertical state, thereby preventing the debris in the storage frame 3 from flowing out.

[0060] refer to Figure 1 and Figure 2 The water surface cleaning device of this application also includes a drive assembly 6, which is disposed at the end of the housing 1 away from the first opening 12, and is used to drive the housing 1 to move.

[0061] The drive assembly 6 includes two propellers 61. Mounting cavities 16 are respectively opened on both sides of the housing 1. The two propellers 61 are respectively disposed in the two mounting cavities 16. The propellers 61 can be driven to rotate so that the housing 1 can move.

[0062] Specifically, the drive assembly 6 also includes a propeller motor, which is connected to the propeller 61 to drive the propeller 61 to rotate. The propeller motor can rotate forward or in reverse.

[0063] Specifically, the mounting cavity 16 is provided through one end away from the first opening 12, and the bottom of the mounting cavity 16 is provided through.

[0064] The water surface cleaning device of this application also includes a radar 62 or an infrared sensor. The radar 62 is located at the other end of the housing 1. The radar 62 and the first opening 12 are located at the same end. The radar 62 is used to detect obstacles. When an obstacle is encountered, the rotation direction of the propeller motor is changed through the signal feedback of the radar 62, switching the propeller motor from forward rotation to reverse rotation.

[0065] Furthermore, there are two radars 62, which are symmetrically arranged with respect to the first opening 12.

[0066] refer to Figure 1 and Figure 3 The roller brush assembly 2 includes a roller brush 21 and a drive member 22.
