Description

Technical Field

[0001] This utility model relates to the field of swimming pool cleaning technology, specifically to a cleaning robot. Background Technology

[0002] Existing pool cleaning machines typically use a screen to isolate the pump impeller from the outside environment, preventing larger impurities from entering the pump. However, during use, the screen may need to be removed for cleaning due to foreign objects getting stuck inside the nozzle. Current technology generally lacks a detection and control mechanism for the screen's installation status when it is removed. If the pump impeller can still start even without the screen installed, its high-speed rotation will expose it, potentially damaging the equipment and posing a safety hazard that could injure the user's hands or body.

[0003] Therefore, existing pool cleaning machines lack effective safety protection and start / stop control mechanisms when the grating is disassembled, resulting in insufficient operational safety. Utility Model Content

When a component is said to be "connected" to another component, it can be directly connected to the other component or it may be in a middle component.

[0020] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used in this invention includes any and all combinations of one or more of the associated listed items.

[0021] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0022] A cleaning robot 100, please refer to Figures 1-3 , Figure 6 The system includes a machine body 110, a waste collection assembly 120, a water pump assembly 130, a protective assembly 140, and a detection assembly 150. The machine body 110 has a suction port 111 and a water outlet 112. The suction port 111 is located at the bottom of the machine body 110, and the water outlet 112 is located at the top of the machine body 110. The waste collection assembly 120 is located inside the machine body 110 and is connected to both the suction port 111 and the water outlet 112, used to filter and collect dirt carried in the water flow. The water pump assembly 130 is located inside the machine body 110 and is used to pump water from the machine body 110. The machine generates suction to allow water to flow through the suction port 111 into the waste collection assembly 120 and be sprayed out from the outlet 112. The water pump assembly 130 is located inside the outlet 112. The protective assembly 140 is detachably mounted on the top of the machine body 110 and covers the outlet 112. The protective assembly 140 has several water outlet holes communicating with the outlet 112. The detection assembly 150 includes a sensor 151 and a detection element 152. The sensor 151 is mounted on the protective assembly 140, and the detection element 152 is mounted inside the machine body 110. The detection element 152 cooperates with the sensor 151 to detect whether the protective assembly 140 is installed.

[0023] The cleaning robot 100 provided by this utility model has a protective component 140 at the water outlet 112 of the machine body 110, which can isolate the water pump assembly 130 from the external environment to prevent foreign objects from entering or users from directly contacting the water pump assembly 130, thereby playing a protective role. The detachable protective component 140 can be easily opened by the user to clean the sewage channel. By setting a sensor 151 on the protective component 140 and a detection component 152 in the machine body 110, the detection component 152 and the sensor 151 work together to detect whether the protective component 140 is installed. The water pump assembly 130 can start and stop according to the sensing result of the detection component 152, realizing intelligent linkage control between the operating status of the water pump assembly 130 and the installation status of the protective component 140, which significantly improves the safety and reliability of the equipment in daily maintenance, cleaning and use.

[0024] In a specific embodiment, the cleaning robot 100 is used for pool cleaning. The cleaning robot 100 also includes a walking structure, through which the cleaning robot 100 moves; optionally, the walking structure includes a tracked structure or a wheeled structure, etc. During the movement of the cleaning robot 100, the side of the cleaning robot 100 facing the pool wall is the bottom of the machine body 110, and the side facing away from the pool wall is the top of the machine body 110; therefore, the suction port 111 faces the pool wall, and water in the pool enters the cleaning robot 100 through the suction port 111.

[0025] In a specific embodiment, both the waste collection component 120 and the water pump component 130 are disposed within the main body 110 of the machine. The water pump component 130 is used to create a negative pressure at the suction port 111, under which pool water enters the cleaning robot 100 through the suction port 111. The waste collection component 120 may include a waste bin, the side wall of which is provided with a filter screen. When the cleaning robot 100 is working, dirt and pool water are sucked into the waste bin through the suction port 111. After being filtered by the filter screen, dirt and impurities are trapped and collected in the waste bin, while the filtered clean water flows back to the outlet 112 through the water flow channel and is sprayed out from there. The water pump component 130 is used to drive the water flow circulation, thereby realizing the circulation and cleaning of the pool water.

[0026] In a specific embodiment, the protective component 140 is disposed at the water outlet 112. The protective component 140 has a hollow structure so that the filtered water can flow out through the water outlet 112. The protective component 140 is mainly used for protection, preventing the user from being injured by the water pump assembly 130 if they put their hands into the water outlet 112 during the operation of the cleaning robot 100; it can also prevent foreign objects (such as leaves, stones, etc.) from entering the robot body through the water outlet 112. Optionally, the protective component 140 is detachably disposed on the robot body 110, and the specific connection method includes, but is not limited to, snap-fit ​​connection, magnetic connection, bolt connection, etc.

[0027] In a specific embodiment, the sensing element 151 and the detection element 152 cooperate to detect whether the protective component 140 is installed on the machine body 110. The detection element 152 can detect the presence or proximity of the sensing element 151 to output a corresponding detection signal. For example, after the protective component 140 is connected to the machine body 110, the detection element 152 can detect the presence of the sensing element 151 and output a first signal indicating that the protective component 140 is connected to the machine body 110; after the protective component 140 is separated from the machine body 110, the detection element 152 can no longer detect the presence of the sensing element 151 and outputs a second signal indicating that the protective component 140 has been removed from the machine body 110.

[0028] In a specific embodiment, the signal output by the detection element 152 can be used to control the start and stop of the water pump assembly 130. For example, after the detection element 152 outputs a first signal, the water pump assembly 130 can continue to work or start according to the first signal, that is, the water pump assembly 130 continuously draws in and discharges pool water from the sewage outlet; after the detection element 152 outputs a second signal, the water pump assembly 130 can stop or remain stopped according to the second signal, that is, the water pump assembly 130 draws in water.

[0029] For some implementation methods, please refer to Figures 3-5 The protective assembly 140 includes a mounting bracket 141 and a grid 142 constructed on the mounting bracket 141. The mounting bracket 141 is detachably connected to the machine body 110. A sensor 151 is disposed on the mounting bracket 141, and a water outlet is formed in the grid 142. Specifically, the mounting bracket 141 and the grid 142 are detachably connected, and the grid 142 is mounted on the side of the mounting bracket 141 facing the machine body 110; the water outlet penetrates the grid 142 to connect to the water outlet 112.

[0030] This utility model, by setting a protective component 140 including a mounting frame 141 and a grid 142 constructed on the mounting frame 141, can form a secondary protection structure using the mounting frame 141 and the grid 142. Both the grid 142 and the mounting frame 141 can prevent foreign objects from entering the water outlet 112; and the grid 142 is mounted on the mounting frame 141, which can protect the grid 142 and prevent the cleaning robot 100 from damaging the grid 142 during operation.

[0031] In a specific embodiment, the mounting frame 141 has a perimeter and a first grille. The perimeter is arranged around the outer circumference of the first grille, and the first grille is disposed in a first space and connected to the perimeter. The first grille includes a plurality of first grille columns arranged at intervals therebetween, thereby forming a hollow structure at the first grille. The orthographic projection of the grille mesh 142 on the mounting frame 141 is located in the first space, and the grille mesh 142 is directly opposite the first grille.

[0032] In a specific embodiment, the bar screen 142 has water outlet holes, and a second bar is provided at the water outlet holes. The second bar includes a plurality of second bar columns arranged at intervals and annular bar columns connected to the second bar columns, thereby forming a hollow structure at the second bar. Optionally, there are two water outlet holes, each connected to a corresponding water outlet 112.

[0033] For some implementation methods, please refer to Figures 3-5 The mounting bracket 141 has a mounting portion 143 on its inner side, and the mounting portion 143 has an internal cavity 144 in which the sensor 151 is embedded. Specifically, the mounting bracket 141 has a mounting portion 143 on the side facing the grid 142. The mounting portion 143 is a hollow structure, and the sensor 151 is housed in the cavity 144 and exposed through the opening of the mounting portion 143.

[0034] This invention provides a mounting portion 143 on the inner side of the mounting bracket 141, and embeds the sensing element 151 in the receiving cavity 144 of the mounting portion 143. The mounting portion 143 can protect the sensing element 151 and prevent it from being damaged. At the same time, the sensing element 151 being placed in the mounting portion 143 can improve the accuracy of the sensing by the detection element 152 and avoid interference from the external environment with the sensing results.

[0035] In a specific embodiment, the mounting portion 143 may be a boss structure protruding from the inner surface of the mounting bracket 141. The mounting portion 143 may be a cylindrical structure, specifically including a cylindrical shape, a square column, etc. Alternatively, the mounting portion 143 may also be a groove structure formed on the inner surface of the mounting bracket 141, thereby forming a receiving cavity 144 to accommodate the sensor 151. Optionally, the mounting portion 143 and the mounting bracket 141 are an integral structure.

[0036] For some implementation methods, please refer to Figure 2 and Figure 3 One of the protective component 140 and the machine body 110 is provided with a snap-fit ​​protrusion 145A, and the other of the protective component 140 and the machine body 110 is provided with a snap-fit ​​groove 146A. The protective component 140 and the machine body 110 are fixed together by the snap-fit ​​engagement of the snap-fit ​​protrusion 145A and the snap-fit ​​groove 146A. Specifically, the side of the mounting bracket 141 facing the grid 142 is provided with a snap-fit ​​protrusion 145A and / or a snap-fit ​​groove 146A, and the corresponding position on the machine body 110 is provided with a matching snap-fit ​​groove 146A and / or a snap-fit ​​protrusion 145A.

[0037] This utility model features a protective component 140 and a machine body 110 connected via a snap-fit ​​protrusion 145A and a snap-fit ​​groove 146A, enabling a quick-release connection. Users can install and remove the protective component 140 without additional tools. Furthermore, the snap-fit ​​structure ensures a stable fit with the machine body 110, preventing the protective component 140 from easily loosening during water spraying. When cleaning the spray nozzles or removing internal foreign objects, users only need to apply slight external force to quickly disassemble and reassemble the protective component 140, significantly improving maintenance convenience. By adopting a quick-release structure, the installation and removal of the protective component 140 are simpler and faster, avoiding the cumbersome and time-consuming steps associated with traditional threaded or screw-fixed structures.

[0038] In a specific embodiment, the mounting bracket 141 has a strip-shaped snap-fit ​​protrusion 145A on the side facing the grid 142, and the corresponding position on the machine body 110 has a snap-fit ​​groove 146A. After the protective component 140 and the machine body 110 are installed, the snap-fit ​​protrusion 145A extends into the snap-fit ​​groove 146A. Optionally, the protective component 140 has multiple snap-fit ​​protrusions 145A arranged in a ring at intervals to ensure the stability of the protective component 140 after it is installed with the machine body 110.

[0039] In a specific embodiment, a secure connection is achieved between the snap-fit ​​protrusion 145A and the snap-fit ​​hole through elastic fit or geometric restraint. Optionally, the end of the snap-fit ​​protrusion 145A may have a barb structure, which is elastic. During the insertion or removal of the snap-fit ​​protrusion 145A from the snap-fit ​​hole, the barb structure is deformed by the compression of the snap-fit ​​hole, allowing the snap-fit ​​protrusion 145A to slide smoothly; after the snap-fit ​​protrusion 145A is inserted into the snap-fit ​​hole, the barb structure can be pushed out of the inner wall of the snap-fit ​​hole to further improve the snap-fit ​​strength.

[0040] In a specific embodiment, the snap-fit ​​protrusion 145A is inserted into and engaged within the snap-fit ​​groove 146A. The elastic fit between the snap-fit ​​protrusions 145A achieves a secure connection, ensuring that the protective component 140 is reliably fixed and not easily loosened during water spray. When the user needs to clean or inspect the water nozzle, they can easily release the snap-fit ​​by pressing or moving the snap-fit ​​protrusion 145A, enabling quick disassembly of the protective component 140.

[0041] For some implementation methods, please refer to Figure 7 One of the protective component 140 and the machine body 110 is provided with a first magnetic member 145B, and the other of the protective component 140 and the machine body 110 is provided with a second magnetic member 146B. The protective component 140 and the machine body 110 are fixed together by the magnetic attraction of the first magnetic member 145B and the second magnetic member 146B. Specifically, the side of the mounting bracket 141 facing the grid 142 is provided with the first magnetic member 145B, and the corresponding position of the machine body 110 is provided with the second magnetic member 146B. The first magnetic member 145B and the second magnetic member 146B are opposite magnets.

[0042] In a specific embodiment, there are multiple first magnetic attractors 145B and multiple second magnetic attractors 146B. The protective assembly 140 is provided with multiple first magnetic attractors 145B arranged in a ring at intervals to ensure the stability of the protective assembly 140 after it is installed with the machine body 110. Optionally, the first magnetic attractors 145B and the second magnetic attractors 146B can be circular magnets, flexible magnetic strips, etc.; or, the first magnetic attractors 145B and the second magnetic attractors 146B can be electromagnets, generating magnetism by energizing them, thereby further improving the strength of the magnetic attraction between the first magnetic attractors 145B and the second magnetic attractors 146B.

[0043] In other embodiments, a magnetic clasp can be provided for one of the protective component 140 and the machine body 110, and a metal component can be provided for the other of the two components. The two components are fixed together by the metal component and the magnetic clasp. The advantage of using only a single magnetic clasp is that it can reduce costs and avoid interference from too many magnets on the detection component 152.

[0044] For some implementation methods, please refer to Figure 2 and Figure 3One of the protective component 140 and the machine body 110 is provided with a positioning post 147, and the other of the protective component 140 and the machine body 110 is provided with a positioning hole 148. The protective component 140 and the machine body 110 form a positioning engagement through the positioning post 147 and the positioning hole 148. Specifically, the mounting bracket 141 has a positioning post 147 and / or a positioning hole 148 on the side facing the grid 142, and the corresponding positioning hole 148 and / or positioning post 147 are provided at the corresponding position on the machine body 110.

[0045] This invention utilizes a positioning post 147 and a positioning hole 148 between the protective component 140 and the machine body 110 to achieve automatic positioning and limiting when the protective component 140 is installed onto the machine body 110, ensuring that the protective component 140 can be accurately aligned and securely installed in a preset position. The positioning post 147 and the positioning hole 148 can employ a clearance fit or a flexible fit structure to balance assembly smoothness and connection reliability.

[0046] In a specific embodiment, the mounting bracket 141 has cylindrical positioning posts 147 on the side facing the grid 142, and the machine body 110 has corresponding positioning holes 148. After the protective component 140 and the machine body 110 are installed, the positioning posts 147 extend into the positioning holes 148. Optionally, the protective component 140 has multiple positioning posts 147 arranged in a ring at intervals to ensure that the protective component 140 can be correctly installed on the machine body 110.

[0047] In a specific embodiment, the shape of the positioning post 147 differs from that of the snap-fit ​​protrusion 145A described above. It is understood that the positioning post 147 serves a positioning function, and therefore does not necessarily enhance the connection. Furthermore, the volume of the positioning post 147 can be smaller than that of the snap-fit ​​protrusion 145A to avoid increasing the weight of the protective assembly 140. Preferably, the positioning post 147 can be integrally formed with the main body of the mounting bracket 141. Optionally, at least one positioning post 147 can be provided between two adjacent snap-fit ​​protrusions 145A.

[0048] For some implementation methods, please refer to Figure 2 The top of the machine body 110 has a through hole 113, and the sensor 151 and the detection element 152 are located at opposite ends of the through hole 113. Specifically, the through hole 113 communicates with the external space of the machine body 110; the detection element 152 is disposed in the through hole 113. After the protective assembly 140 and the machine body 110 are installed, the sensor 151 extends at least partially into the through hole 113. Therefore, the sensor 151 and the detection element 152 are located at opposite ends of the through hole 113, so that the detection element 152 can sense the detection element 152.

[0049] This invention provides a through hole 113 on the machine body 110, and the through hole 113 can correspond to the mounting part 143. The mounting part 143 extends into the through hole 113, which can stably fix the sensing element 151 and place it close to the detection element 152. At the same time, the through hole 113 can also prevent the detection element 152 from being exposed, thereby protecting the detection element 152.

[0050] In a specific embodiment, the through hole 113 can be a circular stepped hole, comprising a positioning section and a mounting section. The positioning section has a larger diameter and depth than the mounting section, and is used to accommodate the detection element 152. The mounting section is located away from the opening of the through hole 113, and the signal lead of the detection element 152 is led out from the mounting section. This ensures that the detection element 152 is fixed in the through hole 113 and also protects the lead of the detection element 152. Of course, in other embodiments, the through hole 113 can also be quadrilateral or other shapes, without specific limitations.

[0051] In a specific embodiment, after the protective component 140 and the machine body 110 are installed, the mounting portion 143 extends into the through hole 113, and the receiving cavity 144 of the mounting portion 143 communicates with the through hole 113. Optionally, the mounting portion 143 can be a cylindrical shape adapted to the shape of the through hole 113, or other shapes. Optionally, the mounting portion 143 and the through hole 113 can be an interference fit, so that the mounting portion 143 and the through hole 113 can fit more tightly, preventing water from entering the through hole 113 and damaging the detection element 152. In other embodiments, a rubber ring can be provided on the outer periphery of the mounting portion 143 or the inner wall of the through hole 113 to improve sealing and installation stability.

[0052] For some implementation methods, please refer to Figure 8 The cleaning robot 100 also includes a control component 160 and a prompting component 170. The control component 160 is electrically connected to both the detection component 152 and the prompting component 170. When the detection component 152 detects that the protective component 140 is not installed, the control component 160 controls the prompting component 170 to issue a prompt signal. Specifically, the control component 160 may include a microcontroller, such as a CPU, PLC, or ARM processor. The control component 160 can receive electrical signals from the detection component 152 and determine whether the protective component 140 is properly installed based on the received electrical signals, then controls the prompting component 170 to issue a prompt signal.

[0053] This invention includes a control component 160 and a prompting component 170 within the cleaning robot 100. The control component controls the prompting component 170 to issue corresponding prompts based on the detection results of the detection component 152, thereby improving the intelligence level of the cleaning robot 100 and enhancing the user experience. The prompting component 170 issues prompts to prevent the protective component 140 from being missed or misaligned during installation.

[0054] In a specific embodiment, the prompting component 170 includes a light prompting element. The light prompting element may include a color-emitting LED indicator, and may emit different colors of light to indicate whether the protective component 140 is installed or not. For example, when the detection element 152 detects that the protective component 140 is installed, the light prompting element may emit a green light to indicate installation; when the detection element 152 detects that the protective component 140 is not installed, the light prompting element may emit a red light to indicate not being installed.

[0055] In other embodiments, the prompting component 170 may further include an audio prompt and / or a visual prompt. The audio prompt may include a buzzer or voice module capable of emitting sound to prompt when the protective component 140 is detected as not installed. The visual prompt may be a display screen that can display prompt characters to prompt when the protective component 140 is detected as not installed.

[0056] For some implementation methods, please refer to Figure 6 The water pump assembly 130 includes a motor 131 and an impeller 132. The output shaft of the motor 131 is connected to the impeller 132 to drive the impeller 132 to rotate. The impeller 132 is located inside the outlet 112. Specifically, the motor 131 can be, but is not limited to, a water pump motor 131. The impeller 132 is mounted on the output shaft of the motor 131. The motor 131 drives the impeller 132 to rotate to move liquid (e.g., water). When the motor 131 drives the impeller 132 to rotate, the impeller 132 can generate suction and water flow power. Through negative pressure suction, water flows in through the suction port 111, and the water carries dirt into the machine body 110. Then, by rotating, the water flow is pushed to send the sucked dirty wastewater into the filtration device, and then the filtered clean water is pushed back into the pool, completing the suction-filtration-discharge cleaning cycle.

[0057] In some embodiments, the sensing element 151 is a magnet, and the detection element 152 is a Hall sensor. Specifically, a Hall sensor is a magnetic sensor that utilizes the Hall effect to convert a changing magnetic field into a changing output voltage. Hall sensors have advantages such as simple structure, small size, robustness, wide frequency response range, large dynamic range, long service life, high reliability, and ease of miniaturization and integrated circuit integration.

[0058] In a specific embodiment, the magnet is fixed to the protective component 140, and the Hall sensor is installed in the through hole 113 and electrically connected to the control component 160. When the protective component 140 is correctly installed on the machine body 110, the Hall sensor can sense the magnetic field signal of the magnet. After the control component 160 recognizes the signal, it allows the motor 131 to be powered on and started in normal working condition. When the protective component 140 is removed from the machine body 110, the Hall sensor will no longer detect the magnetic field signal, and the control component 160 will automatically control the motor 131 to remain in an open circuit state. Even if the user accidentally starts the equipment, the impeller 132 will not rotate, thereby effectively avoiding potential safety risks.

[0059] In other embodiments, the detection element 152 may also be a pressure sensor, and the sensing element 151 may be a pressure block. Specifically, the pressure sensor is a device that converts a pressure signal into a measurable electrical signal output. After the protective assembly 140 and the machine body 110 are installed, the pressure block can press down on the pressure sensor to make the pressure sensor continuously output a signal, and the pressure sensor stops outputting a signal after the pressure block is removed.

[0060] In other embodiments, the detection element 152 may also be an infrared sensor, and the sensing element 151 may be a reflector. Specifically, an infrared sensor is a device that uses the physical properties of infrared light to achieve non-contact detection. The infrared sensor can emit infrared light, which is reflected by the reflector, and then the infrared sensor receives the reflected signal. In this way, the infrared sensor can stop outputting a signal after the reflector is removed.
