CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Chinese Patent Application No. 202310040417.X, filed on Jan. 13, 2023, the content of which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The application relates to the technical field of a swimming pool cleaning device, and in particular to a robot swimming pool cleaner with a convenient-to-replace battery.

BACKGROUND

With the rapid development of the present age, a swimming pool (including an underground or over-ground swimming pool) may be installed in many families. The swimming pool is a place for joy and entertainment. Whatever an outdoor swimming pool or an indoor swimming pool, some garbage, bacteria and sludge would be generated at the bottom of the swimming pool after use for a period of time and be easily accumulated in the swimming pool to form dirt. Moreover, while being adsorbed on the bottom of the swimming pool, the dirt would not be effectively cleaned by normally circulating and filtering the water, therefore, the swimming pool is required for periodic cleaning.

A robot swimming pool cleaner (including an over-ground or underground robot) may perform an operation of swimming pool cleaning. Most of common swimming pool robots in the market are wireless and are powered by a battery. However, the biggest drawback lies in that they are short in duration time. When power out, a user needs to salvage the whole robot swimming pool cleaner out of the swimming pool, charges it for a long time, and transports it to the swimming pool which may not be swept cleanly at this time, thereby resulting in low cleaning efficiency and poor user experience.

SUMMARY

For the technical problem in a related art, the present application provides a robot swimming pool cleaner with a convenient-to-replace battery, which may avoid the troublesome process of frequent salvage and charging of a user, and enable a battery pack to be disengaged, when powers out, from a machine and to float on a water surface. The user may directly replace a fully charged battery pack without waiting or salvage, thereby improving the user experience and cleaning efficiency.

All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

The present application provides a robot swimming pool cleaner with a convenient-to-replace battery. As shown in FIGS. 1-5, the robot swimming pool cleaner includes a body 1; the body 1 is provided with a garbage bin 13 and an ejection bin 11 therein. The ejection bin 11 includes a top opening. The garbage bin 13 is located on one side of the ejection bin 11. The garbage bin 13 communicates with an outside world through a sewage suction port 131.

A winding component 2 and a battery module 4 are sequentially installed in the ejection bin 11, preferably an elastic component 3 is disposed in the ejection bin 11 and installed between the winding component 2 and the battery module 4. The battery module 4 is located on top opening, and the battery module 4 is a buoyancy member. An overall density of the battery module 4 is smaller than the density of the water in the swimming pool. An electric wire 5 is wound on the winding component 2. A first end of the electric wire 5 is electrically connected with the body 1, and a second end of the electric wire 5 is wound on the winding component 2, penetrates through the elastic component 3, and electrically connected with a waterproof sealed plug 6. The battery module 4 and the waterproof sealed plug 6 are detachably connected. The waterproof sealed plug 6 is an aviation plug and is provided with a buoyancy plate 43 which facilitates floating thereof on a water surface.

The robot swimming pool cleaner further includes a control component. The control component is respectively connected with the winding component 2 and the battery module 4. When the battery module 4 is fully charged, the control component controls the winding component 2 to wind the electric wire 5, and the waterproof sealed plug 6 and the battery module 4 overcome the elastic force of elastic component 3 under an action of the winding component 2 and are located in the ejection bin 11. When the battery module 4 is in low battery, the control component controls the winding component 2 to unwind the electric wire 5, and the waterproof sealed plug 6 and the battery module 4 are disengaged from the ejection bin 11 under the action of the elastic component 3. For further facilitating replacement for the battery of the robot swimming pool cleaner, when the robot swimming pool cleaner is in low battery, and before the battery module 4 is disengaged from the ejection bin 11, the robot swimming pool cleaner may move towards an edge of the swimming pool automatically, which may be specifically implemented through a sensor or an infrared ray.

In the present embodiment, as the ejection bin 11, the winding component 2, the elastic component 3, the battery module 4 and the control component are provided, on the one hand, a troublesome process of frequent salvage and charging of a user may be avoided, and the battery pack 4 may be disengaged, when powers out or in low battery, from a machine and floats on a water surface, the user may directly replace a fully charged battery pack 42, retract the battery pack 4 into the ejection bin 11 after replacement, and continue to work without waiting or salvage, thereby improving the user experience and cleaning efficiency. On the other hand, even if salvage is needed, the user may directly pull up the electric wire 5 without a hook to pull the machine out of the water surface and then carries the machine ashore, thereby omitting excessive steps. Specifically, the robot swimming pool cleaner may access close to a wall automatically in a state of low battery. When the robot swimming pool cleaner is about to be power off, the control component of the robot swimming pool cleaner releases a signal to a detection circuit of the winding component 2, such that the winding component 2 stops winding. When the waterproof sealed plug 6 and the battery module 4 lose a traction force of the winding component, the elastic component 3 in the ejection bin 11 ejects the whole waterproof sealed plug 6 and the battery module 4 rapidly to be separated from the ejection bin 11, then the battery module 4 floats on the water surface under the action of a buoyancy force, and the user on the bank may pull the battery module ashore, then unscrew the waterproof sealed plug 6, reinsert the charged battery pack 42 into the machine, and then put the machine back to the water surface. Upon reception of an electric signal, the control component controls the winding component 2 to start winding, and the waterproof sealed plug 6 and the battery module are pulled back to the ejection bin 11.

One end of the winding drum 22 is fixedly connected with the output shaft of the winding motor 7, and the other end of the winding drum 22 is rotatably connected with the inner wall of the ejection bin 11 through the rotating shaft 21. The rotating joint 23 is rotatably installed in the winding drum 22, the second end of the electric wire 5 is wound on the winding drum 22, and the first end of the electric wire 5 is electrically connected with the body 1 through the rotating joint.

The fixed plate 31 is fixedly installed in the ejection bin 11 and is located above the winding component 2. The movable plate 33 is slidably installed in the ejection bin 11. Two ends of the spring 32 are fixedly connected with the fixed plate 31 and the movable plate 33 respectively. The fixed plate 31 and the movable plate 33 are respectively provided with a through hole for enabling the electric wire 5 to penetrate through.
