Description

Technical Field

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

[0002] The suction port of existing cleaning robots is usually located at the bottom of the device. Water flows towards the suction port along the direction of travel as the cleaning robot moves, and then enters the trash can through the suction port. Since the suction port is mostly set vertically, the water flow is prone to sharp deflections, turbulence, and energy loss at the point where the flow direction changes, resulting in greater water resistance and affecting the smoothness of sewage flow into the trash can and the suction efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a cleaning robot that can avoid turbulence and large water resistance caused by rapid water flow, effectively reduce energy loss, and improve the smoothness of water flow and the efficiency of sewage suction.

[0004] To achieve the objectives of this utility model, the following technical solution is provided: In a first aspect, this utility model provides a cleaning robot, including a machine body and a waste collection component. The machine body has a first suction port and a water inlet channel. The first suction port is located at the bottom of the machine body, and the water inlet channel is connected to the first suction port. The waste collection component is located inside the machine body and has a second suction port and a collection space. The second suction port is connected to both the first suction port and the collection space, so that water flows sequentially through the first suction port, the water inlet channel, and the second suction port into the collection space. The water inlet channel includes a first flow channel and a second flow channel connected together. The first flow channel is inclined and forms an angle with the second flow channel. The first flow channel is connected to the first suction port. One end of the second flow channel is connected to the first flow channel, and the other end of the second flow channel is connected to the second suction port.

[0005] In one embodiment, the extension length of the first flow channel is greater than the extension length of the second flow channel.

[0006] In one embodiment, the cross-sectional area of ​​the first flow channel gradually decreases from the end where the first flow channel is connected to the first suction port to the end where the first flow channel is connected to the second flow channel.

[0007] In one embodiment, the machine body includes a chassis and an upper shell, the first suction port is disposed on the chassis, the upper shell is connected to the chassis, and the upper shell has a compartment for placing the waste collection component; The first flow channel includes a first sub-flow channel and a second sub-flow channel. The first sub-flow channel is formed on the chassis, and the second sub-flow channel and the second flow channel are formed on the hopper body.

[0008] In one embodiment, the cross-sectional area of ​​the first suction port gradually increases along the direction of water flow.

[0009] In one embodiment, the end of the first flow channel that connects to the first suction port is provided with an arc-shaped transition section.

[0010] In one embodiment, the waste collection assembly further includes a movable baffle, which is disposed at the second suction port and is used to open or close the second suction port.

[0011] In one embodiment, the waste collection assembly further includes a waste bin and a filter unit, the second suction port is disposed at the bottom of the waste bin, the collection space is formed inside the waste bin, an opening is provided on the side wall of the waste bin, and the filter unit is disposed on the side wall and covers the opening.

[0012] In one embodiment, the cleaning robot further includes a water pump assembly disposed inside the main body of the machine. The top of the main body of the machine is provided with a water outlet. The water pump assembly is used to generate suction within the main body of the machine so that water flows sequentially through the first suction port, the water inlet channel and the second suction port into the collection space, and is discharged through the water outlet.

[0013] In one embodiment, the extension direction of the second flow channel is perpendicular to the travel direction of the cleaning robot.

[0014] With the above structural design, water enters from the first suction port at the bottom of the machine body, is first guided by the first flow channel, then smoothly transitions to the second flow channel, and finally enters the second suction port and flows into the collection space.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or it can be in a middle component. 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] Cleaning robots can automatically complete cleaning tasks in homes or commercial spaces, improving cleaning efficiency and reducing manpower burden. In particular, with the widespread use of home and commercial swimming pools, robots for pool cleaning are receiving increasing attention. Over time, the bottom of swimming pools inevitably accumulates debris such as fallen leaves, twigs, plastic bags, and pebbles. If left unattended, this debris will pollute the pool water. Furthermore, sharp debris can endanger swimmers' health. Due to the complex underwater environment and limited underwater visibility, manual cleaning is inefficient, while draining the pool for cleaning incurs significant costs. Therefore, the demand for water-cleaning robots for pool cleaning is growing.

[0023] Existing cleaning robots typically have their suction inlets located at the bottom of the device. Water flows towards the suction inlet as the robot moves, then enters the waste collection assembly. Since the suction inlets are usually vertically positioned, the water flow must change from horizontal to vertical after entering the suction inlet before continuing into the waste collection assembly. During this process, the water flow is prone to abrupt deflections, turbulence, and energy loss at the point of change, resulting in significant water resistance. This not only affects the smooth flow of waste into the waste collection assembly and the suction efficiency but also increases the pump load, leading to higher energy consumption, reduced cleaning effectiveness, and shorter equipment lifespan.

[0024] Please refer to Figures 1 to 6 This utility model provides a cleaning robot 100, including a machine body 10 and a waste collection component 20. The machine body 10 has a first suction port 13 and a water inlet channel 12. The first suction port 13 is located at the bottom of the machine body 10, and the water inlet channel 12 communicates with the first suction port 13. The waste collection component 20 is disposed inside the machine body 10. The waste collection component 20 has a second suction port 21 and a collection space 22. The second suction port 21 communicates with both the first suction port 13 and the collection space 22, so that water flows sequentially through the first suction port 13, the water inlet channel 12, and the second suction port 21 into the collection space 22.

[0025] First, define the direction. Please refer to [the relevant documentation / reference]. Figure 1X is the first direction X, and Y is the second direction Y, which intersect. Optionally, the first direction X and the second direction Y are perpendicular. Optionally, the cleaning robot 100 travels in the first direction X, and when the cleaning robot 100 travels along the horizontal plane (i.e., the first direction X is parallel to the horizontal plane), the second direction Y is the direction of gravity.

[0026] Optionally, the waste collection component 20 is fixedly connected to the machine body 10, or the waste collection component 20 is detachably connected to the machine body 10, without limitation. Optionally, the second suction port 21 is located at the bottom of the waste collection component 20, and when the cleaning robot 100 is placed on a horizontal surface, the first suction port 13 and the water inlet channel 12 are both located below the waste collection component 20.

[0027] The water inlet channel 12 includes a first flow channel 121 and a second flow channel 122 connected together. The first flow channel 121 is inclined and forms an angle with the second flow channel 122. The first flow channel 121 is connected to the first suction port 13. One end of the second flow channel 122 is connected to the first flow channel 121, and the other end of the second flow channel 122 is connected to the second suction port 21.

[0028] Optionally, the first flow channel 121 forms an angle with the travel direction (i.e., the first direction X) of the cleaning robot 100. It is understood that the cleaning robot 100 has a front end and a rear end in the first direction X, and the travel direction of the cleaning robot 100 is from the rear end to the front end. The first flow channel 121 slopes towards the rear end of the cleaning robot 100 from the first suction port 13, that is, the end of the first flow channel 121 that connects to the second flow channel 122 is located behind the first suction port 13, so that sewage can smoothly enter the first flow channel 121. Optionally, the first flow channel 121 and the second flow channel 122 form an angle, so that the slope between the second flow channel 122 and the horizontal plane is steeper than the slope between the first flow channel 121 and the horizontal plane, facilitating water flow from the second flow channel 122 through the second suction port 21 into the collection space 22.

[0029] The cleaning robot 100 in this embodiment of the present invention, through the above-described structural configuration, allows water to enter from the first suction port 13 at the bottom of the main body 10 of the machine, be guided by the first flow channel 121, then smoothly transition to the second flow channel 122, and finally enter the second suction port 21 and flow to the collection space 22. The water inlet channel 12 can achieve a smooth transition of water flow direction, avoiding turbulence and large water resistance generated when the water flow is sharply turned, thereby effectively reducing energy loss, improving the smoothness of water flow and suction efficiency, and helping the waste flow to enter the garbage collection component 20 more concentratedly, reducing the risk of blockage.

[0030] In one embodiment, the extension length of the first flow channel 121 is greater than the extension length of the second flow channel 122. This configuration, with a longer first flow channel 121, allows the water flow to gradually transition from the direction of travel to the vertical direction along a longer, inclined path after entering the inlet channel 12, reducing the magnitude and speed of the change in flow direction and avoiding eddies and turbulence caused by excessively abrupt deflections. Compared to the shorter second flow channel 122, the longer first flow channel 121 not only effectively reduces water flow resistance and energy loss but also allows debris to be more smoothly guided to the second flow channel 122 and into the second suction port 21 under the propulsion of the water flow, thereby improving the efficiency of debris collection.

[0031] Optionally, the extension length of the first flow channel 121 is L1 (not shown in the figure), and the extension length of the second flow channel 122 is L2 (not shown in the figure), satisfying: 1 < L1 / L2 ≤ 3. When L1 is too large, the extension length of the first flow channel 121 is too long, which will increase the size of the machine body 10 and may cause the water flow to be too slow to enter the second suction port 21, reducing the efficiency of dirt collection; when L1 is too small, the extension length of the first flow channel 121 is too small, which cannot effectively slow down the magnitude and speed of the change in water flow direction. Optionally, the ratio of L1 / L2 can be 1.1, 1.3, 1.5, 1.8, 2, 2.2, 2.5, 2.8, or 3.

[0032] In one embodiment, from the end of the first flow channel 121 that is connected to the first suction port 13 to the end of the first flow channel 121 that is connected to the second flow channel 122, the cross-sectional area of ​​the first flow channel 121 gradually decreases.

[0033] Optionally, the cross-sectional area of ​​the first flow channel 121 may gradually and continuously decrease. In some other embodiments, the cross-sectional area of ​​the first flow channel 121 may also decrease abruptly, without limitation. Optionally, the cross-sectional shape of the first flow channel 121 may be approximately circular, square, elliptical, regular polygonal, irregular shape, etc., without limitation.

[0034] With this configuration, the fluid entering the first flow channel 121 from the first suction port 13 can flow in more smoothly, reducing the local resistance when the fluid enters. As the water flows forward in the first flow channel 121 along the flow direction, the cross-sectional area of ​​the first flow channel 121 gradually and continuously decreases. As the area decreases, the flow velocity increases accordingly. The high-velocity water flow can generate strong power, thereby enhancing the waste transport capacity of the entire system and improving the cleaning effect and work efficiency.

[0035] In one implementation, such as Figure 2 and Figure 6 As shown, the machine body 10 includes a chassis 14 and an upper shell 15. The first suction port 13 is located on the chassis 14, and the upper shell 15 is connected to the chassis 14.

[0036] Both the chassis 14 and the upper shell 15 can be made of materials with high structural strength, such as metal materials, high-strength plastics, ceramics, etc. Metal materials include aluminum, aluminum alloys, magnesium alloys, iron and iron alloys, etc.

[0037] The chassis 14 can be a one-piece structure, meaning it is manufactured using a single molding process, such as stamping or casting, without limitation. Alternatively, the chassis 14 can be a split structure, with its various parts connected and fixed by welding, bonding, snap-fitting, screwing, or other methods. Similarly, the structure of the upper shell 15 is similar to that of the chassis 14, and will not be described further. Optionally, the connection method between the chassis 14 and the upper shell 15 can be welding, bonding, snap-fitting, screwing, riveting, magnetic connection, etc., without limitation. It is understood that the chassis 14 and the upper shell 15 can adopt any feasible structure in the art, and this utility model does not impose specific limitations.

[0038] The upper shell 15 has a compartment 151 for placing the waste collection component 20, which facilitates the centralized collection and storage of waste. The first flow channel 121 includes a first sub-flow channel 123 and a second sub-flow channel 124. The first sub-flow channel 123 is formed on the chassis 14, and the second sub-flow channel 124 and the second flow channel 122 are formed on the compartment 151.

[0039] Optionally, the first suction port 13 is located at the bottom of the chassis 14 for directly sucking up waste located at the bottom of the pool during the movement of the equipment, while the second suction port 21 is formed at the chamber 151 of the upper shell 15. Between the first suction port 13 and the second suction port 21, the chamber 151 of the upper shell 15 is internally constructed with a second sub-flow channel 124 and a second flow channel 122, while the chassis 14 is correspondingly constructed with a first sub-flow channel 123. The first sub-flow channel 123 and the second sub-flow channel 124 are connected during assembly to form a complete first flow channel 121, which is sequentially connected to the second flow channel 122 to form the water inlet channel 12.

[0040] Through the cooperative cooperation of the chassis 14 and the upper shell 15, after the water flow enters from the first sewage suction port 13, it can first be guided by the first sub-flow channel 123 of the chassis 14, then smoothly transition to the second sub-flow channel 124 of the upper shell 15, and finally be steadily guided to the second flow channel 122 and enter the second sewage suction port 21. Such arrangement not only optimizes the guiding path of the water flow, avoids turbulence and large water resistance caused by sharp turning of the water flow, but also makes the dirt flow more concentrated and smoothly into the garbage collection assembly 20, reducing the probability of blockage at the inlet. At the same time, the structure that the chassis 14 and the upper shell 15 form the water inlet channel 12 in sections is convenient for manufacturing and assembly, ensures the modularization and structural strength of the parts, and facilitates later maintenance and replacement. As a result, while improving the sewage suction efficiency and reducing energy consumption, the structural rationality and use reliability of the equipment are also enhanced.

[0041] In one embodiment, the cross-sectional area of the first sewage suction port 13 gradually increases along the water flow entering direction.

[0042] Optionally, the water flow enters the first sewage suction port 13 along the traveling direction of the cleaning robot 100, that is, the direction of the water flow entering the first sewage suction port 13 is parallel to the first direction X. In this direction, the cross section of the first sewage suction port 13 gradually increases, that is, the edge of the first sewage suction port 13 is roughly in the shape of an outward flaring bell mouth, so that the range of water flow entering the first sewage suction port 13 is larger, and the sewage suction coverage is wider.

[0043] In other words, in the second direction Y, from the edge of the first sewage suction port 13 adjacent to the traveling surface to the edge where the first sewage suction port 13 communicates with the first flow channel 121, the first sewage suction port 13 is gradually inclined inward. Such arrangement makes the cross-sectional area of the first sewage suction port 13 gradually increase along the water flow entering direction.

[0044] In some embodiments, as Figure 6 shown, the edge of the first sewage suction port 13 is further provided with a flow guiding structure 16, so as to expand the range of water flow entering the first sewage suction port 13, increase the sewage suction coverage, and improve the sewage suction cleaning effect.

[0045] In addition, the flow guiding structure 16 is disposed on the side of the first sewage suction port 13 close to the rear end of the cleaning robot 100, and can also collect impurities that have not entered the first sewage suction port 13. Optionally, in addition to the side of the first sewage suction port 13 close to the rear end of the cleaning robot 100, the flow guiding structure 16 can also extend to both sides of the rear part of the first sewage suction port 13, and the flow guiding structure 16 is roughly in a "U" shape, which facilitates the water flow to enter the first sewage suction port 13.

[0046] In one embodiment, as Figure 3 and Figure 6 shown, an arc transition portion 17 is configured at the end of the first flow channel 121 communicating with the first sewage suction port 13.

[0047] Optionally, the arc-shaped transition section 17 is formed in the chassis 14. When water flows from the first suction port 13 into the first flow channel 121, if the angle at the connection point is relatively sharp, the water flow will collide and become turbulent at that location. This turbulent water flow state will lead to the loss of water flow energy and create greater water resistance. This will not only reduce the water flow speed and affect the efficiency of waste transport, but may also generate greater noise and vibration.

[0048] By setting an arc-shaped transition section 17 between the first flow channel 121 and the first suction port 13, the change in water flow direction is made more gradual, and the water flow in the direction of travel can flow backward along the streamline of the arc-shaped transition section 17, thereby reducing water resistance and thus reducing energy consumption.

[0049] In one implementation, such as Figure 3 As shown, the waste collection assembly 20 also includes a movable baffle 23, which is located at the second suction port 21 and is used to open or close the second suction port 21.

[0050] Optionally, the movable baffle 23 can move relative to the second suction port 21. For example, the movable baffle 23 can move relative to the second suction port 21 to open or close the second suction port 21; or, the movable baffle 23 can rotate relative to the second suction port 21 to open or close the second suction port 21, without limitation.

[0051] Optionally, the shape of the movable baffle 23 is adapted to the second suction port 21, and when the movable baffle 23 is used to close the second suction port 21, the second suction port 21 is located inside the movable baffle 23 in the orthographic projection of the movable baffle 23, so as to prevent dirt from falling from the second suction port 21.

[0052] With this configuration, the second suction port 21 can be covered by the movable baffle 23 to prevent backflow or overflow of waste.

[0053] In one implementation, such as Figure 2 and Figure 3 As shown, the garbage collection assembly 20 also includes a garbage bin 24 and a filter unit 25. The second suction port 21 is located at the bottom of the garbage bin 24, the collection space 22 is formed inside the garbage bin 24, and an opening is provided on the side wall of the garbage bin 24. The filter unit 25 is located on the side wall and covers the opening.

[0054] Optionally, the waste collection component 20 can be detachably connected to the compartment 151 of the upper shell 15. The connection method can be snap-fit, magnetic connection, plug-in connection, etc., without limitation. This setting facilitates the removal of the waste bin 24 when it is necessary to empty waste or replace and clean the waste bin 24.

[0055] Optionally, the movable baffle 23 is located at the bottom of the trash can 24 and is movably connected to the trash can 24. The movable baffle 23 and the trash can 24 can be slidably connected or rotatedly connected, and the specific connection method is not limited.

[0056] The filter unit 25 is used to filter various impurities in the water flow, preventing impurities entering the trash can 24 from entering the water pump assembly 30 through the opening and affecting the normal operation of the water pump assembly 30. The filter unit 25 can be made of materials with good sealing and water-proofing effects, high rigidity, high pressure resistance, high signal penetration, and corrosion resistance, such as aluminum plates with anti-corrosion coatings or stainless steel. Optionally, the filter unit 25 includes a filter screen. Since the filter screen is subjected to strong water flow for a long time, the material selection process needs to select materials with high rigidity and corrosion resistance to ensure the stability of the filter screen's operation.

[0057] Optionally, the filter unit 25 can be installed inside the trash can 24 or connected to the outer periphery of the trash can 24, without limitation. The filter unit 25 and the trash can 24 can be connected and fixed or detached. The specific connection method can be welding, bonding, snap-fitting, screwing, riveting, magnetic connection, etc., without limitation.

[0058] By setting up a waste collection component 20 including a waste bin 24 and a filter unit 25, water mixed with sewage flows into the waste bin 24. The filter unit 25 can retain the sewage in the waste bin 24, while the water can flow out through the filter unit 25 and out of the opening of the waste bin 24, thereby enabling the cleaning robot 100 to filter and collect sewage.

[0059] In one implementation, such as Figure 2 As shown, the cleaning robot 100 also includes a water pump assembly 30 disposed inside the machine body 10. The top of the machine body 10 is provided with a water outlet 18. The water pump assembly 30 is used to generate suction in the machine body 10 so that water flows sequentially through the first suction port 13, the water inlet channel 12 and the second suction port 21 into the collection space 22 and is discharged through the water outlet 18.

[0060] Optionally, the water pump assembly 30 is sandwiched between the chassis 14 and the upper shell 15, and the water pump assembly 30 is also connected to the collection space 22 of the garbage collection device. In one specific embodiment, the opening of the garbage bin 24 is oriented towards the water pump assembly 30, and the water flowing out of the opening through the filter unit 25 can be discharged from the outlet 18 under the suction of the water pump assembly 30.

[0061] In some other embodiments, the water pump assembly 30 may also be replaced by any device that can provide negative pressure, such as a fan or suction cup, and this invention does not limit this.

[0062] Optionally, in the direction of travel of the cleaning robot 100, the first suction port 13, the water inlet channel 12, the second suction port 21, the opening and the water outlet 18 are arranged in sequence to facilitate the smooth flow of water inside the cleaning robot 100.

[0063] With this configuration, the water pump assembly 30 is located inside the machine body 10, which can draw water from the first suction port 13, filter it through the garbage collection assembly 20, and then spray it out through the water outlet 18, thereby achieving automatic cleaning of the travel surface.

[0064] In one implementation, such as Figure 3 As shown, the extension direction of the second flow channel 122 is perpendicular to the travel direction of the cleaning robot 100.

[0065] Optionally, when the cleaning robot 100 travels along the horizontal plane, the extension direction of the second flow channel 122 is the second direction Y, that is, the extension direction of the second flow channel 122 is perpendicular to the first direction X.

[0066] This design allows the water flowing vertically into the trash can 24 to more quickly separate solid waste and liquid under the influence of gravity. Solid waste, due to its higher density, will quickly sink to the bottom of the trash can 24. If the angle at which the water enters the trash can 24 is too small, some trash may bounce back or flow back to the suction port under the impact of the water flow, or even return to the cleaning area, reducing the cleaning effect. The vertical water flow into the trash can 24 ensures that the trash falls smoothly to the bottom, reducing the possibility of backflow and ensuring the continuity and efficiency of the cleaning work. Furthermore, the second flow path, positioned perpendicular to the direction of travel of the cleaning robot 100, can reduce the size of the trash can 24 in the direction of travel, making the overall design of the cleaning robot 100 more compact.

[0067] Please refer to Figure 1 , Figure 2 and Figure 6 The cleaning robot 100 in this embodiment of the present invention also includes a track wheel assembly 40 and a roller brush 50.

[0068] A roller brush 50 is located at the front end of the machine body 10 and is used to wipe away dirt on the travel surface of the cleaning robot 100. Optionally, roller brushes 50 can be provided at both the front and rear ends of the cleaning robot 100. After the front roller brush 50 wipes and cleans the travel surface, the rear roller brush 50 can also clean the residual sewage and dirt on the travel surface, thereby improving cleaning efficiency.

[0069] Track wheel assemblies 40 are located on the left and right sides of the machine body 10 and are used to drive the cleaning robot 100 to move. It is understood that the left and right directions of the machine body 10 are perpendicular to both the first direction X and the second direction Y.

[0070] Specifically, the cleaning robot 100 also includes a drive component (not shown in the figure) disposed inside the machine body 10. The drive component is drivenly connected to the track wheel assembly 40 and is used to drive the track wheel assembly 40 to move.

[0071] In the description of the embodiments of this utility model, it should be noted that the orientation or positional relationship of the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and other indicators are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0072] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the present utility model.
