Description

Technical Field

[0001] This utility model discloses a swimming pool cleaning robot, particularly a pump-push device with switchable nozzle direction and a swimming pool cleaning robot, belonging to the field of automatic cleaning equipment technology. Background Technology

[0002] A pool cleaning robot is a device specifically designed for cleaning swimming pools. It typically consists of a shell made of high-strength, corrosion-resistant engineering plastics that can adapt to the pool's aquatic environment and protect internal components; a drive system composed of a motor and tracks or wheels that allows the robot to move within the pool; some robots are also equipped with multiple drive wheels for flexible steering; and a cleaning system that includes brushes, a suction port, and a filtration system. The brushes are used to scrub dirt off the pool walls and bottom, the suction port is responsible for sucking up impurities from the water, and the filtration system filters the sucked-in water and returns the clean water to the pool.

[0003] Pool cleaning robots, with their high efficiency, intelligence, and convenience, have become a powerful assistant in pool cleaning, providing people with a more relaxed and comfortable pool experience.

[0004] Existing pool cleaning robots are usually equipped with a propulsion pump, which sprays water from the filtration system to generate thrust and assist in propulsion. Currently, the nozzles of the propulsion pumps are located behind the robot's forward direction, and the nozzle direction cannot be adjusted, which brings many inconveniences to the use of the robot. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the fixed nozzle direction of the pool robot propulsion pump in the prior art, which is inconvenient to use, this utility model provides a pump propulsion device and a pool cleaning robot with switchable nozzle direction. It can realize the automatic switching of nozzle direction by driving the baffle to rotate through a counterweight block.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a pump pushing device with switchable nozzle direction. The pump pushing device includes a pump body shell, a baffle assembly and a water pump assembly. The pump body shell is provided with a water inlet, a top nozzle and a rear nozzle. The water pump assembly is located at the water inlet position. The baffle assembly is located inside the pump body shell between the top nozzle and the rear nozzle. The baffle assembly can switch between two states and can block the top nozzle or the rear nozzle respectively.

[0007] A swimming pool cleaning robot includes a pump-push device with switchable nozzle direction and a housing as described above. The pump-push device with switchable nozzle direction is installed inside the housing of the swimming pool cleaning robot. The housing of the swimming pool cleaning robot has a water inlet at the position corresponding to the water inlet, a top water outlet at the position corresponding to the top nozzle, and a rear water outlet at the position corresponding to the rear nozzle.

[0008] The technical solution adopted by this utility model to solve its technical problem further includes:

[0009] The bottom of the pump body housing is provided with a pump body bottom cover.

[0010] The water pump assembly includes a motor and a propeller, with the propeller mounted on the motor shaft and positioned corresponding to the water inlet.

[0011] The top nozzle is located on the top of the pump body housing, and the rear nozzle is located at the rear of the pump body housing. The axes of the top nozzle and the rear nozzle are perpendicular to each other.

[0012] The baffle assembly includes a baffle, a cantilever, and a counterweight. The baffle is installed inside the pump housing and can rotate inside the pump housing. As the baffle rotates, it can switch positions between the top nozzle and the rear nozzle. One end of the cantilever is connected to the baffle, and the other end is connected to the counterweight.

[0013] One end of the baffle is provided with a round shaft, which is installed inside the pump body housing. The other end of the baffle is provided with a drive shaft, which is coaxial with the round shaft.

[0014] The drive shaft extends to the outside of the pump body housing, and the cantilever is set on the outside of the pump body housing.

[0015] The counterweight is made of a high-density material.

[0016] The cantilever of the counterweight is assembled with the baffle at a 90° angle.

[0017] The beneficial effects of this utility model are: the structure of this utility model enables the robot to be applicable to more application scenarios. For example, when cleaning the surface of a swimming pool, the water pump nozzle of the robot faces the rear of the robot, which makes it easier to use the reverse thrust of the pump to propel the robot on the water surface; when cleaning the side wall of the pool, the water pump nozzle is directed towards the top of the machine, which helps to increase the robot's adhesion when cleaning the side wall.

[0026] This embodiment is a preferred embodiment of the present invention. All other embodiments that are the same as or similar to this embodiment in principle and basic structure are within the protection scope of the present invention.

[0027] Please refer to the appendix for details. Figure 1 To be continued Figure 4 This utility model mainly protects a pump pusher device with switchable nozzle direction, which mainly includes a pump body shell 1, a baffle assembly and a water pump assembly. The pump body shell 1 is provided with a water inlet 10, a top nozzle 11 and a rear nozzle 12. The water pump assembly is located at the water inlet 10. The baffle assembly is located inside the pump body shell 1 between the top nozzle 11 and the rear nozzle 12. The baffle assembly can switch between two states and can block the top nozzle 11 or the rear nozzle 12 respectively.

[0028] In this embodiment, a pump body bottom cover 9 is provided at the bottom of the pump body housing 1. The pump body bottom cover 9 can be opened to install baffle components and the like inside, which facilitates assembly operations.

[0029] In this embodiment, the water pump assembly includes a motor 2 and a propeller 3. The propeller 3 is mounted on the shaft of the motor 2 and is positioned corresponding to the water inlet 10. The motor 2 can be mounted on the pump housing 1 or inside the pool cleaning robot. The specific installation position can be set according to actual needs.

[0030] In this embodiment, the top nozzle 11 is located on the top of the pump housing 1 and is typically used to spray water to push the pool cleaning robot downwards. The rear nozzle 12 is located at the rear of the pump housing 1 and is typically used to spray water to propel the pool cleaning robot forward. The water inlet 10 is located at the front of the pump housing 1. In this embodiment, the axes of the top nozzle 11 and the rear nozzle 12 are perpendicular to each other. However, in actual implementation, they can be set to other angles according to actual needs.

[0031] In this embodiment, the baffle assembly includes a baffle 4, a cantilever 7, and a counterweight 8. The baffle 4 is installed inside the pump housing 1 and can rotate within the pump housing 1. As the baffle 4 rotates, it can switch positions between the top nozzle 11 and the rear nozzle 12. One end of the cantilever 7 is connected to the baffle 4, and the other end is connected to the counterweight 8. The counterweight 8 can drive the baffle 4 to rotate. In this embodiment, one end of the baffle 4 is provided with a round shaft 5, which is installed inside the pump housing 1. The other end of the baffle 4 is provided with a drive shaft 6, which is coaxial with the round shaft 5 and extends to the outside of the pump housing 1. The cantilever 7 is located on the outside of the pump housing 1, and the end of the cantilever 7 has a hole. This hole is fixedly fitted onto the drive shaft 6 and tightly fitted into it, allowing it to rotate together with the drive shaft. In specific implementations, the cantilever 7 and the counterweight 8 can also be located inside the pump housing 1 as needed. In this embodiment, the baffle 4 also has a hole, which is tightly fitted into the drive shaft 6. Because the baffle 4, counterweight 8, and drive shaft 6 are all tightly fitted, the baffle 4 and counterweight 8 form a fixed whole. In specific implementation, the baffle 4 and drive shaft 6 can also be designed and manufactured as a single unit. In this embodiment, the counterweight 8 is made of a high-density material to achieve its counterweight effect in water. The cantilever 7 of the counterweight 8 is assembled at a 90° angle with the baffle 4. Under the influence of gravity, the counterweight 8 is always perpendicular to the center of the earth. Because the assembly between the cantilever 7 of the counterweight 8 and the baffle 4 is at a right angle, the baffle 4 is always in a relatively horizontal position.

[0032] In this embodiment, a circular hole is provided inside the pump body housing 1, and a circular shaft 5 is inserted into the circular hole on the pump body housing 1. A clearance fit is formed between the circular shaft 5 and the circular hole on the pump body housing 1 so that the baffle assembly can have a relatively free range of rotation with this shaft hole as the axis in the pump body housing 1.

[0033] This utility model also protects a swimming pool cleaning robot. The aforementioned pump-push device with switchable nozzle direction is installed inside the housing of the swimming pool cleaning robot. A water inlet is provided on the housing of the swimming pool cleaning robot at the position corresponding to the water inlet 10, a top water outlet is provided on the housing of the swimming pool cleaning robot at the position corresponding to the top nozzle 11, and a rear water outlet is provided on the housing of the swimming pool cleaning robot at the position corresponding to the rear nozzle 12. In this embodiment, the motor 2 is fixedly installed inside the housing of the swimming pool cleaning robot.

[0034] Please refer to the appendix for details. Figure 4 To be continued Figure 6 This utility model has the following two main states when in use:

[0035] (1) When the pump pusher is in a horizontal position (see Appendix for details) Figure 5 Under the action of the counterweight 8, the baffle 4 also remains horizontal. At this time, the baffle 4 just covers the top nozzle 11 of the pump body shell 1. The motor 2 drives the propeller 3 to do work, and the water drawn in from the inlet 10 will be discharged from the rear nozzle 12.

[0036] (2) When the pump pusher is switched to a vertical position (see Appendix for details) Figure 6 The counterweight 8 will remain vertical to the center of the earth under the action of gravity. Since the counterweight 8 and the baffle 4 form a fixed assembly at a 90-degree angle, as the vertical angle increases, the top nozzle 11 will be farther away from the baffle 4, and the rear nozzle 12 will be closer to the baffle 4. At this time, the motor 2 drives the propeller 3 to do work, and the water drawn in from the inlet 10 will be discharged from the top nozzle 11.

[0037] The pump-push device in this invention is mainly used in multi-functional pool cleaning robots, typically mounted at the rear of the robot. This robot can clean both the bottom and sidewalls of the pool. Since the pool sidewalls and bottom are approximately at a 90-degree angle, the robot's main body angle changes by 90 degrees when transitioning from the bottom to the sidewall. Based on the characteristics of the pump-push device, when cleaning the bottom of the pool, the pumped water is discharged from the rear nozzle 12. When the robot transitions to cleaning the sidewall, the pumped water is discharged from the top nozzle 11. The discharge from the top nozzle 11 generates a force opposite to the direction of discharge, causing the robot to adhere more tightly to the pool wall, thus increasing friction and improving the cleaning effect on the sidewalls.

[0038] This invention enables the robot to be used in more application scenarios. For example, when cleaning the surface of a swimming pool, the robot's water pump nozzle faces the rear of the robot, which makes it easier to use the reverse thrust of the pump to propel the robot on the water surface. When cleaning the side walls of the pool, the water pump nozzle faces the top of the machine, which helps to increase the robot's adhesion when cleaning the side walls.
