For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] See also Figure 1 and Figure 2 The pool bottom cleaning device of the embodiment of the utility model includes a cleaning assembly 10 and a lowering member 20.

[0032] The cleaning assembly 10 includes an agitator 11 and a filter 12. The agitator 11 is adapted to drive the water at the pool bottom 92 to move by agitation so as to drive the debris at the pool bottom 92 to move. The filter 12 is connected to the agitator 11 and is located on the moving path of the debris, and is used to filter the water so as to trap the moving debris in the filter 12.

[0033] In other words, after the agitator 11 stirs the pool bottom 92, the water at the pool bottom 92 will move, and the water movement will carry the debris at the pool bottom 92 away from the pool bottom and move to the filter element 12. The filter element 12 filters the water and the debris carried by the water. The water passes through the filter element 12, and the debris remains in the filter element 12.

[0034] Preferably, the agitator 11 has a plurality of stirring impellers 111 that can rotate in a horizontal plane. The plurality of stirring impellers 111 are suitable for driving the water body at the pool bottom 92 to move from bottom to top, so as to drive the debris at the pool bottom 92 to move from bottom to top. The filter element 12 is located on the falling path of the debris, and is used to intercept the debris when the debris falls under the action of gravity, so that the debris remains in the filter element 12.

[0035] The lower end of the lowering member 20 is connected to the cleaning assembly 10, and the upper end extends out of the pool top opening 904, so as to lower the cleaning assembly 10 to the pool bottom 92 or pull it out from the pool top opening 904. In this way, the lowering member 20 can lower the cleaning assembly 10 to the pool bottom 92 before the cleaning assembly 10 is cleaned, so as to clean the debris on the pool bottom 92, and can also pull the cleaned cleaning assembly 10 out of the pool top opening 904 after cleaning, so as to separate the cleaned debris from the pool 91.

[0036] Therefore, when the pool bottom cleaning device of the embodiment of the utility model cleans the debris on the pool bottom 92, a person can stand on the ground 93 and operate the lowering member 20 to lower the cleaning component 10 into the pool bottom 92. Then, after the agitator 11 stirs the pool bottom 92, the movement of the water at the pool bottom 92 will carry the debris on the pool bottom 92 away from the pool bottom and move to the filter element 12. At this time, the filter element 12 filters the moving water and debris, so that the debris is trapped in the filter element 12. Then, the cleaning component 10 is pulled out of the pool top opening 904 through the lowering member 20, so that the debris is separated from the pool bottom 92 as the filter element 12 is lifted, thereby achieving the purpose of cleaning the debris on the pool bottom 92.

[0037] In this way, during the cleaning of the pool bottom 92, a person only needs to stand on the ground 93 to lower and lift the lowering member 20 to complete the cleaning of the debris on the pool bottom 92, thereby avoiding manual cleaning in the pool and achieving high cleaning safety and efficiency.

[0038] According to some preferred embodiments of the present invention, refer to Figure 1 and Figure 2 The lowering member 20 is a lowering rope. The lowering rope is flexible and convenient for manual folding and release, so that the cleaning assembly 10 can be pulled out of the pool top opening 904 or placed in the bottom of the pool 91 by folding and releasing the lowering rope.

[0039] According to some preferred embodiments of the present invention, refer to Figure 1 and Figure 2 The agitator 11 is a submersible agitator. The submersible agitator has a motor. A plurality of agitating impellers 111 are connected to the motor. In this way, when the motor is started by remote signal control or electric control, the agitating impellers 111 of the submersible agitator rotate in a horizontal plane, and the agitating impellers 111 can drive the surrounding water to generate strong circulation and tangential flow, thereby driving the debris on the pool bottom 92 to move from bottom to top, so that the debris on the pool bottom 92 can quickly break away from the pool bottom 92.

[0040] According to some preferred embodiments of the present invention, refer to Figure 1 and Figure 2 The cleaning assembly 10 further includes a cable 13. The lower end of the cable 13 is connected to the motor of the submersible mixer, and the upper end extends out of the pool top opening 904. In this way, the submersible mixer can be started or stopped by controlling the power supply or non-power supply of the cable 13.

[0041] According to some preferred embodiments of the present invention, refer to Figure 1 and Figure 2A filter cavity 1201 is formed in the filter element 12 , an upper filter inlet 1202 communicating with the filter cavity 1201 is formed at the top of the filter element 12 , and a lower filter inlet 1203 communicating with the filter cavity 1201 is formed at the bottom of the filter element 12 .

[0042] The cleaning assembly 10 further includes a guide tube 14. The guide tube 14 is connected to the lower filter inlet 1203 and is spaced apart from the pool bottom 92. A guide channel 1401 is formed in the guide tube 14 and is connected in the vertical direction. The agitator 11 is arranged in the guide channel 1401, so that a guide gap 1402 is formed between the agitator 11 and the inner wall of the guide tube 14, which is connected to the lower filter inlet 1203 and suitable for the passage of the debris.

[0043] In this way, when the agitator 11 stirs the pool bottom 92, a portion of the water will move from bottom to top in the guide gap 1402, and then enter the filter chamber 1201 through the lower filter inlet 1203. Then, when this portion of the water and the debris it carries fall downward under the action of gravity, the water passes through the filter element 12 and the debris carried by the water remains in the filter chamber 1201.

[0044] Another part of the water will move from bottom to top outside the guide tube 14. This part of the water can carry the debris into the filter chamber through the upper filter inlet 1202. Then, when this part of the water and the debris it carries fall downward under the action of gravity, the water passes through the filter element 12 and the debris carried by the water also remains in the filter chamber 1201.

[0045] In this way, the water in the pool 91 can be circulated and filtered through the internal and external paths. The filter element 12 has a good interception effect on debris, especially large-volume garbage, which is beneficial to improving the cleaning effect of the debris. The filtered debris can be easily poured out through the upper filter inlet 1202, and the filter element 12 is easy to clean.

[0046] Preferably, see Figure 1 and Figure 2 A stable bracket 142 is formed in the guide tube 14, and the agitator 11 is stably arranged in the guide tube 14 through the stable bracket 142. Further, the guide tube 14 and the stable bracket 142 are both made of stainless steel. The guide tube 14 made of stainless steel has high strength and long service life.

[0047] According to some preferred embodiments of the present invention, refer to Figure 1 and Figure 2 The filter element 12 is a filter net bag, and the pool bottom cleaning device also includes a float 30, and the float 30 is connected above the filter net bag.

[0048] The filter net bag has low cost and is easy to manufacture, but it is easily affected by gravity in water and the upper and lower parts are stacked together, which makes it impossible for the filter element 12 to maintain the above-mentioned internal and external circulation filtering state. The float 30 can float on the liquid surface 905, thereby playing a pulling role on the upper part of the filter net bag, so that the filter net bag always floats above the guide tube 14 in an open state, thereby ensuring that the filter element 12 maintains the internal and external path circulation filtering state for a long time.

[0049] In addition, the float 30 can also accurately display the cleaning area of ​​the cleaning component 10, and when the agitator 11 begins to be placed in the pool bottom 92, the length of the rope and the length of the cable 13 below the float 30 can be adjusted according to the depth of the pool 91, and then the cleaning component 10 is lowered into the pool 91 through the lowering member 20 to clean the pool bottom 92. In addition, during the cleaning process, the more debris the filter net bag intercepts, the heavier the weight of the filter net bag, the deeper the float 30 enters the water, and the lower the height of the portion of the float 30 above the liquid surface 905. By observing the height of the portion of the float 30 above the liquid surface 905, it can be judged whether the filter net bag has reached the corresponding interception amount and whether it is necessary to clean the debris in the filter net bag.

[0050] According to some preferred embodiments of the present invention, refer to Figure 1 and Figure 2 The pool bottom cleaning device further comprises a connecting ring 40, the connecting ring 40 is connected below the float 30, and the upper end of the filter net bag is hung on the connecting ring 40. In this way, the upper port of the filter net bag can be kept open for a long time, so that the sundries can enter conveniently.

[0051] More preferably, the connecting ring 40 is flexible, and the float 30 is connected to the center of the connecting ring 40 via a flexible bracket.

[0052] According to some preferred embodiments of the present invention, refer to Figure 1 and Figure 2 The pool bottom cleaning device also includes a connecting cloth cover 50, the upper end of the connecting cloth cover 50 is hung on the connecting ring 40, and the lower end is hung with the filter net bag, and a connecting channel 501 that runs through the upper and lower parts is formed in the connecting cloth cover 50, and the connecting channel 501 is connected to the filter cavity 1201 to guide the debris entering from the connecting ring 40 into the filter net bag.

[0053] Such a configuration can enhance the connection strength between the filter net bag and the connection ring 40, and the connection cloth cover 50 has a certain flexibility, can better adapt to the flow of water in the pool 91 without damage, and has a long service life. In addition, debris is not easy to be dispersed from the connection cloth cover 50, so that the debris can be fully intercepted by the filter net bag.

[0054] Furthermore, the connecting cloth cover 50 is made of plastic cloth, which is water-proof, thereby making it more difficult for debris to be dispersed.

[0055] According to some preferred embodiments of the present invention, refer to Figure 1 and Figure 2 The pool bottom cleaning device also includes a plurality of anti-dumping brackets 60, which are spaced apart around the outer peripheral wall of the guide tube 14, and the upper end of each anti-dumping bracket 60 is connected to the outer peripheral wall of the guide tube 14, and the lower end is arranged away from the outer peripheral wall of the guide tube 14 relative to its upper end, and the lower end is suitable for abutting against the pool bottom 92.

[0056] In this way, when the stirrer 11 stirs the debris on the pool bottom 92, the water on the pool bottom 92 will flow, which will cause the guide tube 14 to easily tip over, thereby affecting the cleaning effect of the debris on the pool bottom 92. The multiple anti-tipping brackets 60 can effectively prevent the guide tube 14 from tipping over during the debris cleaning process, thereby ensuring the cleaning effect of the debris on the pool bottom 92. In addition, the anti-tipping brackets 14 can also support the guide tube 14, ensuring that the guide tube 14 can always be a certain distance away from the pool bottom 92.

[0057] In a specific example, there are eight anti-dumping brackets 60 , and the eight anti-dumping brackets 60 are evenly spaced along the outer peripheral wall of the guide tube 14 at an interval angle of 45 degrees.

[0058] According to some preferred embodiments of the present invention, refer to Figure 1 and Figure 3 The pool bottom cleaning device further comprises an operating rod 70. The lower end of the operating rod 70 is connected to the cleaning assembly 10, and the upper end thereof extends out of the pool top opening 904, so as to drive the cleaning assembly 10 to move.

[0059] In this way, after cleaning an area of ​​the pool bottom 92, the operating rod 70 can be driven to move, thereby driving the cleaning component 10 to move in the pool 91, and then the cleaning component 10 is moved to different areas of the pool bottom 92, and different areas of the pool bottom 92 are cleaned, thereby achieving the purpose of comprehensive cleaning of the pool bottom 92.

[0060] According to some preferred embodiments of the present invention, refer to Figure 1 and Figure 3 The operating rod 70 includes an operating handle 71, a first connecting rod 72 and a second connecting rod 73. The operating handle 71 is located above the pool top opening 904. The upper end of the first connecting rod 72 is hinged to the operating handle 71. One end of the second connecting rod 73 is hinged to the lower end of the first connecting rod 72, and the other end is hinged to the cleaning assembly 10.

[0061] By way of further example, the first connecting rod 72 includes an upper supporting rod 721 and a lower supporting rod 722 arranged in sequence along the up-down direction. The two ends of the upper supporting rod 721 are respectively hinged to the lower supporting rod 722 and the operating handle 71. The second connecting rod 73 includes a first supporting rod 731, a second supporting rod 732 and a third supporting rod 733 arranged in sequence along the horizontal direction. The first supporting rod 731 is hinged to the lower supporting rod 722. The two ends of the second supporting rod 732 are respectively hinged to the first supporting rod 731 and the third supporting rod 733. The third supporting rod 733 is hinged to the cleaning assembly 10.

[0062] In this way, when a person stands in a fixed position and operates the operating handle 71 to move the cleaning component 10, the operating rod 70 can be flexibly deformed, thereby driving the cleaning component 10 to move to multiple different areas, avoiding the defect that the cleaning component 10 cannot be moved to a corner position due to the limitation of the operating rod 70 by the pool wall 91, thereby expanding the cleaning range of the cleaning component 10.

[0063] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
