Description

Technical Field

[0001] This utility model relates to the field of intelligent underwater equipment technology, especially swimming pool cleaning technology, and more specifically, to a walking device for a swimming pool robot and a swimming pool robot. Background Technology

[0002] In the field of smart homes, the application of robots is becoming more and more widespread and in-depth. They are frequently seen in every corner of the home, undertaking diverse tasks such as cleaning and security, gradually replacing human labor to complete complex home and yard work, and greatly improving the convenience and comfort of people's lives.

[0003] In the realm of pool cleaning technology, pool robots, as professional automated pool cleaning devices, are increasingly popular among users, with more and more families choosing to use them to maintain the cleanliness of their pools. They can move autonomously underwater, efficiently cleaning dirt and debris from the bottom and walls of the pool, providing a convenient and efficient solution for daily pool maintenance.

[0004] However, in practical use, current pool cleaning robots have revealed a series of problems that urgently need to be solved. Among them, the clogging of the trash collection device is particularly prominent. With long-term operation, the robot accumulates a large amount of trash, such as leaves, hair, and sand, during the cleaning process. This accumulated trash easily leads to clogging of the collection device. Once clogged, the robot cannot effectively collect trash, severely impacting the continuity and effectiveness of its cleaning work, reducing user experience, and limiting the further promotion and application of pool cleaning robots in the pool cleaning market.

[0005] For example, Chinese utility model patent 202420040003.7, published on December 3, 2024, includes a shell and at least two wheels, each wheel defining a first plane. A flow channel is formed at the bottom of the shell from the water inlet to the end of the pool robot, and the flow channel has an arc-shaped guiding surface. The main purpose is to provide an arc-shaped flow channel on the bottom surface, ensuring that no tangent line on the arc-shaped structure is parallel to the plane of travel, thereby allowing water to flow backward along the flow channel during the pool robot's movement. This allows most of the water flow in the travel direction to flow backward along the flow channel, preventing excessive resistance at the front end of the first plane and thus reducing energy consumption.

[0006] Therefore, how to enable pool robots to effectively collect garbage even when the garbage collection device is clogged is a technical problem that the industry urgently needs to solve. Utility Model Content

[0007] The present invention aims to overcome the shortcomings of the prior art and provide a garbage collection device and a swimming pool robot to solve the problem that when the garbage collection device in the existing swimming pool robot becomes clogged, the swimming pool robot can no longer effectively collect garbage.

[0008] The technical solution adopted by this utility model is to provide a garbage collection device, which is installed inside a swimming pool robot. It includes a shell set inside the swimming pool robot body, a water inlet at the bottom of the shell, which is connected to the sewage suction port of the body, and a number of filter holes through the top wall and / or side wall of the shell.

[0009] At least one drain pipe is provided through the side wall and / or top wall of the shell. A filter collection screen is detachably provided on the inner wall of the drain pipe. A first valve is provided on the drain pipe. The first valve is normally closed. When the filter hole is blocked or the water flow is not smooth, the first valve on the drain pipe is opened, so that the liquid in the shell is discharged to the outside of the shell through the drain pipe.

[0010] In one method, the mesh size of the filter collection screen is larger than the aperture of the filter through-holes. Debris that could clog the filter through-holes will not completely block the filter collection screen, allowing water to flow out of the housing through the drain pipe.

[0011] In one embodiment, a second valve is installed inside the water inlet to prevent debris inside the casing from flowing back into the suction port.

[0012] In one embodiment, a filter collection screen is installed at one end of the drain pipe near the interior of the housing. This reduces the occurrence of drain pipe blockage and prevents debris inside the drain pipe from affecting the opening or closing of the first valve.

[0013] In one embodiment, the first valve is a solenoid valve, which is electrically connected to a controller inside the machine body. The solenoid valve offers more powerful control functions and a higher degree of automation, allowing the controller to more flexibly control the opening and closing of the first valve and reducing the possibility of malfunction.

[0014] In one embodiment, a pressure sensor is installed inside the housing and electrically connected to the controller. The pressure sensor detects the pressure value inside the housing and transmits the detected pressure value to the controller. When the controller detects an abnormal pressure inside the housing based on the value transmitted from the pressure sensor, the controller controls the first valve to open, allowing the liquid inside the housing to be discharged into the housing through the drain pipe.

[0015] In one embodiment, a flow sensor is installed inside the suction port. The flow sensor is electrically connected to the controller and is used to detect the liquid flow rate at the suction port, transmitting the detected flow rate value to the controller. When the controller detects a decrease in the flow rate at the suction port based on the value transmitted from the flow sensor, the controller controls the first valve to open, ensuring that the liquid inside the housing is not blocked and unable to drain out of the housing.

[0016] In one embodiment, the first valve is a mechanical safety valve. The first valve also does not require electrical connection to the controller, reducing initial installation costs and simplifying maintenance.

[0017] A swimming pool robot includes a body with a processing chamber inside. A suction port communicating with the processing chamber is located at the bottom of the body, and a drain port communicating with the processing chamber is located on the side and / or top of the body. A vane pump is located near the drain port within the processing chamber. A controller is located within the body and electrically connected to the vane pump. The vane pump is used to discharge water from the processing chamber to the drain port and create a negative pressure within the processing chamber, allowing water to enter the processing chamber from the suction port. A walking device is located at the bottom of the body for moving the swimming pool robot. A waste collection device is located within the processing chamber to treat the water entering the processing chamber from the suction port, leaving waste inside the waste collection device. The treated water continues to be discharged from the processing chamber swimming pool robot through the drain port.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This utility model provides a garbage collection device and a swimming pool robot, which solves the problem that when the garbage collection device of the existing swimming pool robot becomes clogged, the swimming pool robot cannot continue to effectively collect garbage, thus enabling the swimming pool robot to collect garbage more effectively.

Detailed Implementation

[0024] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0025] Example 1

[0026] This embodiment provides a swimming pool robot, including a body 100, a processing chamber 104 formed within the body 100, a suction port 101 communicating with the processing chamber 104 at the bottom of the body 100, and a drain port 102 communicating with the processing chamber 104 at the side and / or top of the body 100. A vane pump 103 is disposed within the processing chamber 104 near the drain port 102. A controller is disposed within the body 100, and the controller is electrically connected to the vane pump 103. The vane pump 103 is used to pump water from the processing chamber 104 to the drain port 102. The water is discharged externally, and a negative pressure is formed in the treatment chamber 104, allowing water to enter the treatment chamber 104 from the suction port 101. A walking device 700 is provided at the bottom of the body 100. The walking device 700 is used to move the position of the pool robot, so that the pool robot can collect garbage from multiple places. A garbage collection device is provided in the treatment chamber 104. The garbage collection device is used to treat the water entering the treatment chamber 104 from the suction port 101, leaving the garbage in the garbage collection device. The treated water continues to be discharged from the treatment chamber 104 from the drain port 102.

[0027] In this embodiment, the walking device 700 is a walking wheel or a walking track. In this embodiment, the walking wheel has a simple structure and flexible motion control, which can quickly adjust the turning and posture of the pool robot. The walking track has a large contact area, high stability, and can easily cross obstacles and climb slopes. When there is a lot of garbage in the pool, the walking track can be used to collect the garbage.

[0028] Example 2

[0029] This embodiment provides a waste collection device installed inside the aforementioned swimming pool robot. It includes a shell 200 disposed inside the body 100. The bottom end of the shell 200 is provided with a water inlet 201, which is connected to the suction port 101 of the body 100. The top wall and / or side wall of the shell 200 are provided with a plurality of filter holes 202. By increasing a sufficient number of filter holes 202 and drain pipes 300, the shell 200 is less likely to be blocked.

[0030] At least one drain pipe 300 is provided through the side wall and / or top wall of the housing 200. A filter collection screen 400 is detachably provided on the inner wall of the drain pipe 300. A first valve 500 is provided on the drain pipe 300. The first valve 500 is normally closed. When the filter passage 202 is blocked or the water flow is obstructed, the first valve 500 on the drain pipe 300 opens, allowing the liquid inside the housing 200 to be discharged to the outside of the housing 200 through the drain pipe 300. By adding the drain pipe 300, water can be discharged from the housing 200 more easily through the drain pipe 300 when the filter passage 202 is blocked.

[0031] In a more specific embodiment, the mesh size of the filter collection screen 400 is larger than the aperture of the filter through-hole 202. In this embodiment, debris that could clog the filter through-hole 202 will not completely block the filter collection screen 400, allowing water to flow out of the housing 200 through the drain pipe 300.

[0032] In a more specific embodiment, a second valve 600 is provided inside the inlet 201. The second valve 600 is used to prevent debris inside the housing 200 from flowing back into the suction port 101. In this embodiment, the second valve 600 is preferably a one-way valve made of rubber or silicone (such as a butterfly one-way valve and a swing one-way valve. One-way valves control the flow of fluid and have various embodiments in the prior art. The specific structure of the one-way valve will not be described in detail here). The one-way valve does not require connection to a controller, which helps to reduce equipment costs. The rubber or silicone one-way valve is made of simple and readily available materials, thereby further reducing production costs.

[0033] In a more specific embodiment, the filter collection net 400 is disposed at one end of the drain pipe 300 near the inside of the housing 200, thereby reducing the occurrence of blockage in the drain pipe 300 and preventing the presence of debris in the drain pipe 300 from affecting the opening or closing of the first valve 500.

[0034] In a more specific embodiment, the first valve 500 is a solenoid valve, which is electrically connected to a controller inside the body 100 (solenoid valves control fluid flow and switching in various embodiments in the prior art; the specific structure of the solenoid valve will not be described in detail here). The solenoid valve has a more powerful control function and a higher degree of automation, making it easier for the controller to flexibly control the opening and closing of the first valve 500, and reducing the possibility of the first valve 500 malfunctioning.

[0035] In this embodiment, a pressure sensor is installed inside the housing 200. The pressure sensor is electrically connected to the controller. The pressure sensor is used to detect the pressure value inside the housing 200 and transmit the detected pressure value to the controller. When the controller detects an abnormal pressure inside the housing 200 based on the value transmitted from the pressure sensor, the controller controls the first valve 500 to open, so that the liquid inside the housing 200 is discharged into the housing 200 through the drain pipe 300 (the pressure sensor has various embodiments in the prior art, and the specific structure of the pressure sensor will not be described in detail here).

[0036] In this embodiment, a flow sensor is installed inside the suction port 101. The flow sensor is electrically connected to the controller. The flow sensor is used to detect the liquid flow rate at the suction port 101 and transmit the detected flow rate value to the controller. When the controller detects a decrease in the flow rate at the suction port 101 based on the value transmitted from the flow sensor, the controller controls the first valve 500 to open, so that the liquid in the housing 200 will not be unable to drain into the housing 200 due to blockage (the flow sensor has various embodiments in the prior art, and the specific structure of the flow sensor will not be described in detail here).

[0037] Example 3

[0038] In this embodiment, a pressure sensor and / or a flow sensor are provided in the processing chamber 104, or a pressure sensor and / or a flow sensor are provided in the drain outlet 102, and both the pressure sensor and the flow sensor are electrically connected to the controller. When the pressure value of the pressure sensor decreases, or when the flow value of the flow sensor decreases, the controller controls the first valve 500 to open.

[0039] In this embodiment, the effect is the same as that in Embodiment 2 (where the pressure sensor is located inside the housing 200 and the flow sensor is located inside the suction port 101).

[0040] Other technical features are the same as in Embodiment 2, and have the same technical effects as in Embodiment 2, and will not be described in detail in this embodiment.

[0041] Example 4

[0042] In this embodiment, the first valve 500 is a mechanical safety valve (such as a full-bore spring-loaded safety valve and a wear-resistant safety valve). When the filter through-hole 202 is blocked, the housing 200 continues to absorb water and debris, causing the internal pressure of the housing 200 to increase. This pressure then applies to the valve disc of the mechanical safety valve. The pressure acting on the valve disc overcomes the spring force on the mechanical safety valve, causing the valve disc to open and allowing water to flow through the first valve 500 and out of the housing 200.

[0043] In this embodiment, compared with embodiment 2, it is not necessary to install a pressure sensor inside the housing 200, nor is it necessary to install a flow sensor at the suction port 101, and the first valve 500 does not need to be electrically connected to the controller to achieve the same effect.

[0044] Other technical features are the same as in Embodiment 2, and have the same technical effects as in Embodiment 2, and will not be described in detail in this embodiment.

[0045] This embodiment provides a garbage collection device and a swimming pool robot, which solves the problem that when the garbage collection device of an existing swimming pool robot becomes clogged, the swimming pool robot cannot continue to effectively collect garbage, thus enabling the swimming pool robot to collect garbage more effectively.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the technical solution of this utility model, and are not intended to limit the specific implementation of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the claims of this utility model should be included within the protection scope of the claims of this utility model.
