Technical Field

[0001] The utility model relates to the technical field of swimming pool cleaning machines, in particular to an upper shell and an automatic swimming pool cleaning machine capable of reducing walking resistance. Background Art

[0002] A swimming pool cleaning machine is a machine that can clean stains on the bottom or wall of a swimming pool and the like on the surface of the swimming pool. In order to facilitate the movement of the swimming pool cleaning machine, a handle is often provided on the swimming pool cleaning machine.

[0003] For example, the Chinese design patent publication number: CN307532580S discloses a swimming pool cleaning machine. In the prior art, the handle of the swimming pool cleaning machine often protrudes outside the upper shell. When the swimming pool cleaning machine is moving, the design of the handle generates a large resistance to the oncoming water flow, which increases the walking resistance of the swimming pool cleaning machine, reduces the speed of the swimming pool cleaning machine, and thus reduces the cleaning efficiency of the swimming pool cleaning machine. Therefore, the present utility model proposes an upper shell and an automatic swimming pool cleaning machine that reduce the walking resistance, which are different from the prior art, to solve the above technical problems. Utility Model Content

[0012] The outer walls of the outer side of the outer shell and the outer side of the inner shell are both provided with protrusions, and the two groups of protrusions transition to one side of the outer side of the inner shell and the outer side of the outer shell respectively.

[0013] By adopting the above technical solution, the protrusions are transitionally processed toward the outer side surfaces on both sides of the inner shell and the outer side surfaces on both sides of the outer shell, so that water flows through the outer side surfaces on both sides of the inner shell and the outer side surfaces on both sides of the outer shell, reducing the resistance of the water flow to the automatic swimming pool cleaner.

[0014] Optionally, a groove is provided on the second shell, and the groove and the protrusion are matched and engaged with each other.

[0021] The automatic swimming pool cleaning machine comprises the upper shell for reducing walking resistance mentioned above.

[0022] In summary, the present invention has at least one of the following beneficial effects:

[0023] First, during the walking process, since the handle, the outer side of the outer shell and the outer side of the inner shell are on the same smooth and streamlined arc surface, the handle generates less resistance to the oncoming water flow, thereby reducing the walking resistance of the automatic swimming pool cleaner, increasing the speed of the automatic swimming pool cleaner, and thus improving the cleaning efficiency of the automatic swimming pool cleaner;

DETAILED DESCRIPTION

[0039] The following is combined with Figure 1-13 The utility model is described in further detail.

[0040] Please refer to the attached figure in the instruction manual Figure 1-11 The utility model provides an embodiment: an upper shell for reducing walking resistance, including an inner shell 2, an outer shell 1 is installed on the outer wall of the inner shell 2, and an outer shell positive outer side surface 4 is arranged on the outer wall of the outer shell 1. The inner shell 2 includes a first shell 10 and a second shell 13, and the first shell 10 is installed on the outer wall of the second shell 13. The handle 3 is integrally formed with the first shell 10, and an inner shell positive outer side surface 5 is arranged on the outer wall of the inner shell 2. The outer shell positive outer side surface 4, the inner shell positive outer side surface 5 and the outer side surface of the handle 3 are on the same arc surface, and the arc surface is a smooth streamlined surface. The outer shell 1 is provided with outer shell side side surfaces 8 on both sides, and the inner shell 2 is provided with outer shell side side surfaces 7 on both sides.

[0041] When the automatic pool cleaner moves inside the swimming pool, since the handle 3, the outer side surface 4 of the outer shell and the outer side surface 5 of the inner shell are on the same smooth and streamlined arc surface, the handle 3 generates little resistance to the oncoming water flow, thereby reducing the resistance of the automatic pool cleaner, increasing the speed of the automatic pool cleaner, and thus improving the cleaning efficiency of the automatic pool cleaner.

[0042] Please refer to the attached figure in the instruction manual Figure 1-11 A through hole is formed between the inner shell 2 and the handle 3. After the water flows through the outer side surfaces 8 on both sides of the outer shell, part of the water flows through the through hole between the inner shell 2 and the handle 3, and the other part of the water flows through the outer side surface of the handle 3, further reducing the resistance of the water flow to the automatic pool cleaning machine.

[0043] Please refer to the attached figure in the instruction manual Figure 3 and 4 The outer walls of the outer shell front side 4 and the inner shell front side 5 are both provided with protrusions 11, and the two groups of protrusions 11 transition to the outer shell side sides 7 and the outer shell side sides 8, respectively. Since the protrusions 11 transition to the outer shell side sides 7 and the outer shell side sides 8, the water flows through the outer shell side sides 7 and the outer shell side sides 8, reducing the resistance of the water flow to the automatic swimming pool cleaning machine.

[0044] Please refer to the attached figure in the instruction manual Figure 3 and 4 The second housing 13 is provided with a groove 12, and the groove 12 is matched and engaged with the protrusion 11. The design of the protrusion 11 and the groove 12 being matched and engaged with each other can prevent the first housing 10 and the second housing 13 from being misaligned.

[0045] Please refer to the attached figure in the instruction manual Fig. 9 The first shell 10 and the second shell 13 are fixedly connected by a fastener 14, and the fastener 14 is fixedly connected to the inner wall of the first shell 10 and the inner wall of the second shell 13. The fastener 14 is arranged in the inner cavity of the upper shell to prevent the fastener 14 from forming resistance to the water flow.

[0046] Please refer to the attached figure in the instruction manual Fig.12 , 13 The second housing 13 is provided with a display light 6 penetrating the first housing 10. The step surface at the outer end of the display light 6 abuts against the inner wall of the first housing 10, and fixing members 9 are provided on both sides of the inner end of the display light 6, and the fixing members 9 are fixedly connected to the second housing 13. The display light 6 and the fixing members 9 are made of polycarbonate material, which has excellent transparency, heat resistance and impact resistance. The display light 6 can conveniently indicate the position of the automatic pool cleaning machine, and the fixing members 9 can fix the position of the display light 6 to prevent it from shaking.

[0047] The automatic swimming pool cleaning machine comprises the upper shell for reducing walking resistance mentioned above.

[0048] Working principle: when using the upper shell for reducing walking resistance, the upper shell structure is installed on the automatic swimming pool cleaner, and the automatic swimming pool cleaner is started to walk inside the swimming pool. During the walking process, since the handle 3, the outer side surface 4 of the outer shell and the outer side surface 5 of the inner shell are on the same smooth and streamlined arc surface, the handle 3 generates little resistance to the oncoming water flow, thereby reducing the walking resistance of the automatic swimming pool cleaner, increasing the speed of the automatic swimming pool cleaner, and thus improving the cleaning efficiency of the automatic swimming pool cleaner.

[0049] Furthermore, since the projections 11 are transitionally processed toward the outer side surfaces 7 on both sides of the inner shell and the outer side surfaces 8 on both sides of the outer shell, the water flows through the outer side surfaces 7 on both sides of the inner shell and the outer side surfaces 8 on both sides of the outer shell, thereby reducing the resistance of the water flow to the automatic swimming pool cleaner. At the same time, after the water flows through the outer side surfaces 8 on both sides of the outer shell, part of the water flows through the through holes between the inner shell 2 and the handle 3, and the other part of the water flows through the outer side surface of the handle 3, thereby further reducing the resistance of the water flow to the automatic swimming pool cleaner.

[0050] The design of the protrusion 11 and the groove 12 fitting together can prevent the first shell 10 and the second shell 13 from being misaligned. The position of the automatic swimming pool cleaner can be conveniently indicated by the display light 6. The position of the display light 6 can be fixed by the fixing part 9 to prevent it from shaking.
