Description

Technical Field

[0001] This application relates to a swimming pool robot with a semi-enclosed flow channel, belonging to the field of power tool technology. Background Technology

[0002] With the continuous development of automation technology, robots have been widely applied in many areas of daily life. Pool cleaning robots are intelligent devices designed to meet the needs of efficient pool cleaning. They can automatically complete a thorough cleaning of the pool bottom and walls, while simultaneously filtering the pool water, effectively improving cleaning efficiency and water quality. During the cleaning process, the robot removes dirt, algae, and sediment from the pool walls and bottom surfaces through the rotating friction of its scrubbing rollers.

[0003] However, existing pool cleaning robots still face several technical challenges in actual operation. When the robot climbs and operates on the vertical pool wall, it needs to rely on the pump motor to provide high water flow power to generate sufficient suction force to maintain its stable adhesion to the pool wall surface. This process causes the pump motor to operate under high load for a long time, resulting in high energy consumption and affecting the overall energy efficiency and endurance of the machine.

[0004] Therefore, there is an urgent need for an optimized fluid structure design to improve the operational stability of the pump system under complex working conditions, reduce energy consumption, and effectively prevent gas from mixing in during water discharge, so as to ensure that the robot can maintain efficient and stable cleaning performance when climbing walls and in transition areas. Utility Model Content

[0005] The purpose of this application is to overcome the problems existing in the prior art and provide a swimming pool robot with a semi-enclosed flow channel, which can ensure that the water suction efficiency of the pumping mechanism operates stably under a relatively stable low energy consumption state.

[0006] To solve the above technical problems, this utility model provides a swimming pool robot with a semi-enclosed flow channel, including a shell and a pumping mechanism and a waste container disposed within the shell; the flow channel is formed inside the shell, which passes sequentially from the water inlet of the shell through the waste container and the pumping mechanism, and finally connects to the water outlet of the shell; the pumping mechanism includes an impeller, which is disposed inside an impeller guide shroud; the bottom of the impeller guide shroud has an impeller water inlet, and the top has an impeller water outlet; a water collection shroud is provided outside the impeller guide shroud, and a cavity is formed inside the water collection shroud to accommodate the liquid flowing out of the waste container.

[0007] Furthermore, a sealing box is provided inside the housing, the impeller guide cover is located on the top of the sealing box, and the periphery of the water collection cover is sealed to the top cover of the sealing box and together define a water collection cavity with an opening facing the garbage box.

[0008] Furthermore, the opening of the water collection cover is a gradually expanding opening facing the garbage box, and the height of the top wall of the water collection cover is lower than the height of the impeller outlet.

[0009] Furthermore, a roller brush is provided at the bottom of the housing, and the roller brush is located on the opposite side of the opening of the water collection cover.

[0010] Furthermore, the top wall of the water collection cover is provided with a through hole, and the top of the impeller guide shroud extends out from the through hole provided in the water collection cover, and the through hole is sealed to the impeller guide shroud.

[0011] Furthermore, a filter screen is provided between the waste box and the pumping mechanism.

[0012] Furthermore, the inlet of the impeller guide shroud is shaped like a funnel with an expanded diameter.

[0013] Furthermore, the impeller's drive motor is located inside the sealed box, and the impeller is positioned near the water outlet and is coaxially equipped with a guide cone.

[0014] Compared with the prior art, this application achieves the following beneficial effects: 1. By setting a water collection shroud outside the impeller guide shroud of the pumping mechanism to form a water collection cavity, the water flowing out of the garbage box is effectively collected and guided smoothly into the impeller inlet. This avoids the problems of easy water leakage and large pressure loss in traditional open flow channels, making the water flow path more compact and the sealing better, improving pumping efficiency and reducing energy consumption; 2. This application achieves unidirectional guidance of water flow, preventing water flowing in from the inlet from flowing out of the shell through the gaps in the shell, improving the pressure stability in the flow channel, effectively preventing air from being drawn into the pump body from the side of the roller brush during the wall climbing process, avoiding cavitation, dry running or "air lock" phenomena, and ensuring that the pumping mechanism is always in a state of high-efficiency hydraulic load.

[0018] In the following description of this application, the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not mean that the device must have a specific orientation.

[0019] To make the technical means, creative features, objectives and effects of this application easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this application.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0021] This application discloses a swimming pool robot with a semi-enclosed flow channel, comprising a shell 1 and a pumping mechanism and a waste container 2 disposed inside the shell 1. A flow channel is formed inside the shell 1, which starts from the water inlet of the shell 1, passes sequentially through the waste container 2 and the pumping mechanism, and finally connects to the water outlet of the shell 1.

[0022] The pumping mechanism includes an impeller 3, which is installed inside an impeller guide shroud 4. The impeller guide shroud 4 has an impeller inlet at the bottom and an impeller outlet at the top. A water collection shroud 5 is provided outside the impeller guide shroud 4, and a cavity is formed inside the water collection shroud 5 to collect the liquid flowing out of the garbage box 2.

[0023] The housing 1 also includes a sealing box 9, with the impeller guide shroud 4 fixed to the top of the sealing box 9. The periphery of the water collection shroud 5 is sealed to the top cover of the sealing box 9, together forming a water collection chamber with an opening facing the garbage box 2. The opening of the water collection shroud 5 is a gradually expanding opening structure facing the garbage box 2, and the height of the top wall of the water collection shroud 5 is lower than the height of the impeller outlet.

[0024] Water enters through the inlet of housing 1, flows sequentially through garbage box 2 and filter screen 7, and is collected in the water collection chamber of water collection cover 5. This structure effectively reduces water diffusion and energy loss before entering the pumping mechanism, improves the continuity of the flow channel and the stability of the flow velocity, thereby enhancing the robot's ability to clean dirt from the bottom and walls of the pool.

[0025] A roller brush 6 is located at the bottom of the housing 1, opposite the opening of the water collection cover 5. During the robot's wall climbing process, this opposing layout helps prevent air from entering the flow channel from the roller brush 6 area or other gaps in the housing 1, avoiding air-liquid mixing that could lead to a decrease in suction, ensuring efficient operation of the impeller 3, and maintaining good adhesion of the robot to the pool wall.

[0026] The top wall of the water collection cover 5 is provided with a through hole 5a. The top of the impeller guide shroud 4 passes through the through hole 5a and extends out. The through hole 5a and the impeller guide shroud 4 are connected by a sealing structure to achieve a sealed fit. This design not only improves the overall sealing performance, but also makes the structure more compact, avoiding the problem of insufficient internal space in the housing 1 due to the addition of the water collection cover 5, and also facilitates assembly and maintenance.

[0027] A filter screen 7 is installed between the waste box 2 and the pumping mechanism to intercept small impurities and prevent them from entering the pumping mechanism and causing blockage or affecting the working efficiency of the impeller 3.

[0028] The impeller guide shroud 4 has an enlarged, trumpet-shaped inlet, which helps to increase the inlet area, reduce the inlet velocity, and improve inlet stability. The drive motor of the impeller 3 is located inside the sealing box 9, providing power to the impeller 3. A guide cone 8 is coaxially mounted on the side of the impeller 3 near the outlet, which can effectively guide the water flow direction, reduce eddies and energy loss, accelerate the water discharge speed, and further improve pumping efficiency.
