Description

Technical Field

[0001] This utility model relates to the field of pool cleaning machine technology, specifically to a waste collection component and a pool cleaning machine. Background Technology

[0002] Existing pool cleaning machines typically incorporate magnets and other sensors on the waste collection components and Hall effect sensors within the machine to detect whether the waste bins are properly installed using magnetic induction signals. However, over long-term use, the environment to be cleaned may contain fine metal impurities or iron filings, which are easily attracted to the magnets. When these iron filings adhere to the magnet's surface, they are often located inside the waste collection components and are firmly attached, making them difficult for users to clean during routine maintenance. This increases maintenance complexity and inconvenience. Furthermore, these metal impurities can alter the strength and distribution of the magnetic field, affecting the overall detection accuracy of the machine. Utility Model Content

[0003] The purpose of this invention is to provide a waste collection component and a pool cleaning machine that can avoid interference from iron filings and other debris on the magnetic sensing element, improve the in-situ detection accuracy of the waste collection component, and facilitate subsequent waste cleaning and equipment maintenance.

[0004] To achieve the objectives of this utility model, the following technical solution is provided: In a first aspect, this utility model provides a waste collection component for a swimming pool cleaner. The waste collection component includes a bottom wall, side walls, and a magnetic sensor. The bottom wall has a suction port and a shielding component, which is movably disposed at the suction port to shield it when not in operation. The side walls and the bottom wall enclose a collection space for containing waste. The side walls extend away from the bottom wall to form an extension, which is spatially isolated from the collection space. The magnetic sensor is placed on the outer side wall of the extension and is used to cooperate with a magnetic sensor on the swimming pool cleaner to detect whether the waste collection component is installed on the swimming pool cleaner.

[0005] In one embodiment, the extension has a mounting portion protruding outwards in a direction away from the extension, and the mounting portion has an internal cavity for receiving, and the magnetic sensing element is disposed in the cavity.

[0006] In one embodiment, the magnetic sensing element is arranged laterally within the receiving cavity.

[0007] In one embodiment, the bottom wall includes a first bottom wall and a second bottom wall, the first bottom wall and the second bottom wall being disposed at a distance on both sides of the suction port, and the first bottom wall and the second bottom wall being offset from each other in the extending direction of the side wall.

[0008] In one embodiment, the first bottom wall is lower than the second bottom wall, and the magnetic sensing element is located on the side wall near the second bottom wall.

[0009] In one embodiment, the sidewall is provided with an opening and a filter unit, the filter unit being connected to the sidewall and covering the opening, for filtering the garbage stream entering the collection space through the suction port.

[0010] In one embodiment, a flip cover is rotatably provided on the side wall, the flip cover being located on the side of the side wall away from the bottom wall, for opening or closing the waste collection assembly.

[0011] Secondly, this utility model also provides a swimming pool cleaning machine, including a waste collection component as described in any one of the various embodiments of the first aspect.

[0012] In one embodiment, the pool cleaning machine further includes a body, a track wheel assembly, a cleaning roller brush, and a magnetic induction sensor. The waste collection assembly is detachably disposed within the body. The track wheel assembly is disposed on the left and right sides of the body for driving the body to move on the bottom or wall of the pool. The cleaning roller brush is disposed at the bottom or front end of the body for cleaning waste in the pool. The magnetic induction sensor is disposed within the body and corresponds to the magnetic sensing element for detecting whether the waste bin assembly is installed in place.

[0013] In one embodiment, the body includes a blocking part for connecting with and enclosing the bottom wall of the waste collection assembly to form an isolation cavity. The suction port and the isolation cavity are located on opposite sides of the blocking part, and the magnetic sensing element is disposed in the isolation cavity.

[0014] By placing the magnetic sensing element on the extension formed by the side wall away from the bottom wall, the magnetic sensing element and the collection space are effectively misaligned in space, thereby preventing iron filings or metal impurities in the collection space from being adsorbed onto the side wall corresponding to the magnetic sensing element. This avoids the impurities affecting the magnetic field strength and distribution of the magnetic sensing element, which can improve the detection accuracy and operational stability of the whole machine. At the same time, it also avoids the difficulty in cleaning impurities adsorbed on the side wall, making subsequent waste cleaning and equipment maintenance easier. Attached Figure Description

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] With the increasing prevalence of home and commercial swimming pools, pool cleaning machines have garnered significant attention. Over time, pool bottoms inevitably accumulate debris such as leaves, twigs, plastic bags, and pebbles. If left unattended, this debris can pollute the pool water. Furthermore, sharp objects can endanger swimmers' health. Due to the complex underwater environment and limited underwater visibility, manual cleaning is inefficient, while pumping water out for cleaning incurs considerable costs. Therefore, the demand for pool cleaning machines is growing.

[0023] Existing pool cleaning machines typically incorporate magnetic sensors, such as magnets, on the waste collection components and Hall effect sensors within the machine to detect whether the waste bins are properly installed. However, over time, small metal impurities or iron filings in the environment being cleaned easily attract the magnets. When these filings adhere to the magnet's surface, they are difficult to clean during routine maintenance due to their location within the waste collection components and their strong adhesion, increasing maintenance complexity and inconvenience. Furthermore, the iron filings covering the magnetic sensor surface alter the magnetic field strength and distribution, causing signal deviations or even loss from the sensor, potentially leading to misjudgments. For example, even if the waste collection components are actually installed, interference with the magnetic field may prevent the sensor from correctly identifying the installation status, causing the system to incorrectly determine that the components are not installed, resulting in the machine failing to start or frequent alarms. Therefore, the problem of iron filings easily attracting magnetic sensors in existing technologies not only increases the user's cleaning and maintenance burden but also directly affects the detection accuracy and reliability of the pool cleaning machine, reducing its intelligent performance and user experience.

[0024] The waste collection component of the pool cleaning machine in this embodiment will be described in detail below.

[0025] Please refer to Figures 1 to 5 This utility model embodiment provides a garbage collection component 10 for a swimming pool cleaner 100, the garbage collection component 10 including a bottom wall 11, a side wall 12 and a magnetic sensing element 15.

[0026] A suction port 111 is provided on the bottom wall 11, and a cover 16 is provided. The cover 16 is movably provided at the suction port 111 to cover the suction port 111 when not in operation. The side wall 12 and the bottom wall 11 enclose a collection space 13 for containing garbage. The side wall 12 extends in a direction away from the bottom wall 11 to form an extension 14. The extension 14 is spatially isolated from the collection space 13.

[0027] Optionally, the waste collection component 10 includes a waste bin, which comprises a bottom wall 11, side walls 12, and an extension 14. The waste bin can be made of a material with high structural strength, specifically metal, high-strength plastic, ceramic, etc. Metal materials include aluminum, aluminum alloy, magnesium alloy, iron, and iron alloys. Optionally, the waste bin can be a one-piece structure, meaning it is manufactured using a single molding process, such as stamping or casting, without limitation. The waste bin can also be a modular structure, with the bottom wall 11, side walls 12, and extension 14 connected and fixed by welding, bonding, snap-fitting, plugging, screwing, riveting, etc. Optionally, the wall thickness of the bottom wall 11, side walls 12, and extension 14 can be approximately the same, meaning the thickness of the side walls 12 can be approximately uniform, and the thicknesses of the bottom wall 11, side walls 12, and extension 14 can also be approximately the same.

[0028] Optionally, there are multiple sidewalls 12, each connected to the bottom wall 11, forming a collection space 13. The end of the collection space 13 opposite to the bottom wall 11 is open, and the extension 14 is connected to at least one of the sidewalls 12. Optionally, the extension 14 is disposed near the bottom wall 11 and extends in a direction away from the bottom wall 11; in other embodiments, the extension 14 is connected to the end of the sidewall 12 away from the bottom wall 11, that is, the extension 14 is disposed near the opening of the collection space 13 and extends in a manner away from the opening of the collection space 13. All of the above embodiments are possible and no specific limitation is imposed.

[0029] The shield 16 is movable relative to the suction port 111 to open or block the suction port 111. For example, the shield 16 is movable relative to the suction port 111 to open or block the suction port 111; or, the shield 16 is rotatable relative to the suction port 111 to open or block the suction port 111, without limitation.

[0030] Optionally, the shape of the shield 16 is adapted to the suction port 111. In the non-working state, when the shield 16 blocks the suction port 111, the suction port 111 is located inside the shield 16 in the orthographic projection of the shield 16, preventing dirt from falling out of the suction port 111.

[0031] With this configuration, the suction port 111 can be covered by the shield 16 to prevent dirt from flowing back or overflowing.

[0032] The magnetic induction element 15 is placed on the outer wall 12 of the extension 14 and is used to cooperate with the magnetic induction sensor 50 on the pool cleaner 100 to detect whether the garbage collection assembly 10 is installed on the pool cleaner 100.

[0033] The magnetic sensing element 15 can be, but is not limited to, a magnet, a magnetoresistive element, an AMR element, a TMR element, etc. Optionally, the magnetic sensing element 15 is disposed on the side of the extension 14 facing away from the collection space 13. The magnetic sensing element 15 and the extension 14 can be connected and fixed by means of bonding, snap-fitting, screwing, riveting, etc., without limitation.

[0034] In this embodiment of the utility model, the garbage collection component 10 places the magnetic sensing element 15 on the extension 14 formed by the side wall 12 away from the bottom wall 11. The magnetic sensing element 15 and the collection space 13 are effectively misaligned in space, thereby preventing iron filings or metal impurities in the collection space 13 from being adsorbed onto the side wall 12 corresponding to the magnetic sensing element 15. This avoids the impurities affecting the magnetic field strength and distribution of the magnetic sensing element 15, which can improve the detection accuracy and operational stability of the whole machine. At the same time, it also avoids the impurities adsorbed on the side wall 12, which is difficult to clean, and facilitates subsequent garbage cleaning and equipment maintenance.

[0035] In one implementation, such as Figure 1 and Figure 2 As shown, an installation part 17 is protruding on the extension 14. The installation part 17 protrudes in a direction away from the extension 14. The internal structure of the installation part 17 has a receiving cavity 171, and the magnetic sensing element 15 is disposed in the receiving cavity 171.

[0036] The mounting part 17 and the extension part 14 can be an integral structure, that is, the mounting part 17 and the extension part 14 are integrally molded. The integral molding process can be stamping, casting, etc., without limitation. The mounting part 17 and the extension part 14 can also be a separate structure, and the mounting part 17 and the extension part 14 can be connected and fixed by welding, bonding, snap-fitting, plugging, screwing, riveting, etc.

[0037] Optionally, the mounting portion 17 is disposed on the side of the extension 14 facing away from the bottom wall 11 and the collecting space 13, and protrudes from the surface of the extension 14 facing away from the bottom wall 11. The interior of the mounting portion 17 is a hollow structure to form a receiving cavity 171 for accommodating the magnetic sensing element 15. Optionally, the magnetic sensing element 15 is disposed in the receiving cavity 171 and can be fixed in the receiving cavity 171 by means of bonding, snap-fitting, or injection molding, so that the magnetic sensing element 15 can be securely installed and not easily fall off.

[0038] Optionally, the inner wall surface of the receiving cavity 171 is also provided with a snap-fit ​​part (not shown in the figure), which is used to abut against the magnetic sensing element 15 to better fix the magnetic sensing element 15.

[0039] By placing the magnetic sensor 15 inside the receiving cavity 171 of the mounting portion 17, the magnetic sensor 15 can be effectively covered and protected, preventing it from being displaced or damaged by water flow or garbage collisions during long-term use. On the other hand, the magnetic sensor 15 is placed on the outside of the extension portion 14 and isolated from the collection space 13, further reducing the magnetic sensor 15's adsorption effect on metal impurities such as iron filings inside the collection space 13.

[0040] In one embodiment, the magnetic sensing element 15 is horizontally disposed within the receiving cavity 171. It is understood that, taking a magnet as an example, the height direction of the magnet is parallel to the depth direction of the receiving cavity 171. This arrangement results in a more uniform distribution of the magnetic field in the vertical direction, with the magnetic field lines on both sides extending further along the height direction of the magnet, while the influence range in the cross-sectional direction is smaller. This facilitates the cooperation between the magnetic sensing element 15 and the magnetic induction sensor 50, while preventing the magnetic sensing element 15 from attracting iron filings or metal impurities within the collection space 13.

[0041] In one implementation, such as Figure 1 and Figure 2 As shown, the bottom wall 11 includes a first bottom wall 112 and a second bottom wall 113. The first bottom wall 112 and the second bottom wall 113 are spaced apart on both sides of the suction port 111, and the first bottom wall 112 and the second bottom wall 113 are staggered in the extending direction of the side wall 12.

[0042] Optionally, a suction port 111 is formed between the first bottom wall 112 and the second bottom wall 113. The trash can also includes a connecting wall 114, one end of which is connected to one of the first bottom wall 112 and the second bottom wall 113, and the other end extends toward the other of the first bottom wall 112 and the second bottom wall 113 in the extending direction of the side wall 12.

[0043] Specifically, taking the connection between the connecting wall 114 and the first bottom wall 112 as an example, one end of the connecting wall 114 is connected to the first bottom wall 112, and the other end extends toward the second bottom wall 113 in the extension direction of the side wall 12, and can extend to be approximately flush with the second bottom wall 113. In the extension direction of the side wall 12, the connecting wall 114 is located between the first bottom wall 112 and the second bottom wall 113, and a suction port 111 is formed between the connecting wall 114 and the second bottom wall 113. The shielding member 16 is movably connected to the second bottom wall 113 and the connecting wall 114.

[0044] With this configuration, the bottom wall 11 includes a first bottom wall 112 and a second bottom wall 113 that are offset in the extension direction of the side wall 12. The height difference between the first bottom wall 112 and the second bottom wall 113 allows dirt to be stored in the collection space 13 and accumulate at the lower bottom wall 11, preventing dirt from accumulating on the shield 16 and preventing sewage from entering the collection space 13 through the suction port 111, thus ensuring the cleaning efficiency of the pool cleaner 100.

[0045] In one implementation, such as Figure 2 As shown, the first bottom wall 112 is lower than the second bottom wall 113, and the magnetic sensing element 15 is located on the side wall 12 near the second bottom wall 113.

[0046] Understandably, when the pool cleaner 100 is placed on a horizontal surface, the first bottom wall 112 is lower than the second bottom wall 113, meaning the first bottom wall 112 is positioned below the second bottom wall 113, and the first bottom wall 112 is closer to the horizontal surface than the second bottom wall 113. With this arrangement, after waste enters the collection space 13, heavier waste falls under gravity and accumulates on the first bottom wall 112. The magnetic sensor 15 is positioned on the side wall 12 near the second bottom wall 113, at a greater distance from the first bottom wall 112, avoiding any influence from the magnetic sensor 15 on the adsorption of metallic impurities within the collection space 13. This improves the overall detection accuracy and operational stability of the machine, facilitating subsequent waste cleaning and equipment maintenance.

[0047] In one implementation, such as Figure 1 As shown, the side wall 12 is provided with an opening 121 and a filter unit 122. The filter unit 122 is connected to the side wall 12 and covers the opening 121, and is used to filter the garbage flow that enters the collection space 13 through the suction port 111.

[0048] The filter unit 122 is used to filter various impurities in the water flow, preventing impurities from entering the collection component and then entering the water pump assembly 70 through the opening 121, thus affecting the normal operation of the water pump assembly 70. The filter unit 122 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 122 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.

[0049] Optionally, the filter unit 122 is in the shape of a grid, and has multiple elongated filter holes arranged in an array. The grid-like structure achieves the interception effect of dirt, allowing the dirt to be collected in the collection space 13. In actual use, the structure of the filter unit 122 can also be modified according to the usage requirements to enable it to clean specific debris. This utility model does not impose specific limitations in this regard.

[0050] Optionally, the filter unit 122 can be disposed within the collection space 13 or on the side of the side wall 12 facing away from the collection space 13, without limitation. The filter unit 122 can be fixedly connected to the side wall 12 or it can be detachably connected. The specific connection method can be welding, bonding, snap-fitting, screwing, riveting, magnetic connection, etc., without limitation.

[0051] By setting up an opening 121 and a filter unit 122, water mixed with sewage flows into the trash can. The filter unit 122 can retain the sewage in the trash can, while the water can pass through the filter unit 122 and flow out from the opening 121, thereby achieving the filtration and collection of sewage by the pool cleaner 100.

[0052] In one implementation, such as Figure 1 and Figure 2 As shown, a flip cover 18 is rotatably provided on the side wall 12. The flip cover 18 is located on the side of the side wall 12 away from the bottom wall 11 and is used to open or close the waste collection assembly 10.

[0053] Optionally, the flip cover 18 is located at the opening of the collection space 13 opposite to the bottom wall 11, and is used to open or cover the opening of the collection space 13. Optionally, the flip cover 18 and the side wall 12 can be rotatably connected by means of snap-fit, screw-fit, riveting, etc., without limitation. One end of the flip cover 18 is rotatably connected to the side wall 12, and the other end can move toward or away from the opening of the collection space 13.

[0054] Optionally, a handle 19 is provided on the flip cover 18, which allows the operator to hold the handle 19 and move the waste collection component 10, and also to hold the handle 19 and rotate the flip cover 18, facilitating the movement and opening and closing of the waste collection component 10.

[0055] With this configuration, when in operation, the flip cover 18 closes the waste collection component 10 to prevent waste from overflowing from the collection space 13; when the waste is collected or the collection space 13 is full, the flip cover 18 rotates to open the waste collection component 10 and empty the waste. The waste collection component 10 can be reused, and the operation is simple and convenient.

[0056] Please refer to Figures 3 to 5 This utility model provides a swimming pool cleaning machine 100, including the waste collection component 10 of this utility model embodiment. The swimming pool cleaning machine 100, using the waste collection component 10 of this utility model embodiment, can effectively prevent the magnetic sensing element 15 of the waste collection component 10 from adsorbing iron filings, thereby avoiding magnetic field interference, ensuring the in-situ detection accuracy of the waste collection component 10 and the reliable operation of the swimming pool cleaning machine 100.

[0057] In one implementation, such as Figure 3 and Figure 4 As shown, the pool cleaning machine 100 also includes a body 20, a track wheel assembly 30, a cleaning roller brush 40, and a magnetic induction sensor 50. The waste collection assembly 10 is detachably installed inside the body 20.

[0058] The body 20 can be made of materials with high structural strength, such as metals, high-strength plastics, ceramics, etc. Metals include aluminum, aluminum alloys, magnesium alloys, iron, and iron alloys. The body 20 can be a one-piece structure, meaning it is a one-piece structure manufactured using a single molding process. The single molding process can be stamping, casting, etc., without limitation.

[0059] The body 20 can also be a split structure. Optionally, the body 20 includes a chassis 21 and an upper shell 22, which can be connected and fixed by welding, bonding, snap-fitting, screwing, etc. Optionally, the upper shell 22 forms a compartment for placing the waste collection component 10, facilitating centralized collection and storage of waste; the chassis 21 is provided with a sludge inlet, which communicates with the waste collection component 10, for directly sucking up waste located at the bottom of the pool during the movement of the pool cleaner 100. Through the coordinated operation of the chassis 21 and the upper shell 22, water flows through the sludge inlet into the body 20 and then into the waste collection component 10. At the same time, the split structure of the chassis 21 and the upper shell 22 facilitates manufacturing and assembly, ensures modularity of parts and structural strength, and helps with later maintenance and replacement. Thus, while improving sludge suction efficiency and reducing energy consumption, it also enhances the structural rationality and reliability of the equipment.

[0060] It is understood that the body 20 can also adopt any feasible body 20 structure in the field, and this utility model does not impose any specific limitations.

[0061] Track wheel assemblies 30 are disposed on the left and right sides of the body 20 and are used to drive the body 20 to move on the bottom or wall of the pool. Specifically, the pool cleaning machine 100 also includes a drive assembly (not shown in the figure) disposed inside the body 20. The drive assembly is drivenly connected to the track wheel assembly 30 and is used to drive the track wheel assembly 30 to move.

[0062] A cleaning roller brush 40 is located at the bottom or front end of the body 20 and is used to clean dirt and debris in the pool. It is understood that the swimming pool cleaner 100 travels in a forward-backward direction, and the body 20 has a front and rear end facing opposite directions in this direction. Optionally, the cleaning roller brush 40 is located at the front end of the body 20 to scrub dirt and debris on the travel surface of the swimming pool cleaner 100. In other configurations, the cleaning roller brush 40 may also be located at the bottom of the swimming pool cleaner 100, and positioned near the rear end of the body 20. With this configuration, after the front cleaning roller brush 40 scrubs and cleans the travel surface, the rear cleaning roller brush 40 can also clean any remaining wastewater and dirt and debris on the travel surface, improving cleaning efficiency.

[0063] A magnetic induction sensor 50 is installed inside the body 20 and corresponds to the magnetic induction element 15, used to detect whether the waste collection component 10 is installed in place.

[0064] The magnetic induction sensor 50 includes, but is not limited to, a Hall sensor or a reed switch. Optionally, after the waste collection assembly 10 is installed in place, the magnetic induction sensor 50 detects the position information of the magnetic sensing element 15, then the circuit is connected, and the magnetic induction sensor 50 sends an installation signal. When the waste collection assembly 10 is not installed in place, the magnetic induction sensor 50 cannot detect the position information of the magnetic sensing element 15. Depending on the calculation logic in the actual application, the magnetic induction sensor 50 may respond by not sending any signal or sending an installation-in-place signal.

[0065] Optionally, the waste collection component 10 includes a plurality of magnetic sensing elements 15 spaced apart, and a plurality of magnetic sensing sensors 50 are correspondingly provided inside the body 20. The plurality of magnetic sensing sensors 50 are correspondingly provided with the plurality of magnetic sensing elements 15 to detect whether the waste collection component 10 is installed in place from different positions, thereby more accurately locating the position status of the waste collection component 10.

[0066] Optionally, a motor housing assembly 60 is provided within the main body 20. The motor housing assembly 60 includes a motor housing and electronic components. The motor housing can be any waterproof structure feasible in the art, and its material can be any waterproof material feasible in the art, without limitation. The motor housing is used to install waterproof electronic components, including but not limited to the magnetic induction sensor 50, circuit board, motor, battery, etc., to prevent short circuits caused by contact with water.

[0067] With this configuration, the pool cleaner 100 can improve the in-situ detection accuracy of the waste collection component 10 and ensure the reliable operation of the pool cleaner 100.

[0068] In one implementation, such as Figure 4 As shown, the pool cleaning machine 100 also includes a water pump assembly 70 disposed inside the body 20. The top of the body 20 is provided with a water outlet 23. The water pump assembly 70 is used to generate suction inside the body 20 so that water flows sequentially through the inlet and the suction port 111 into the collection space 13 and is discharged through the water outlet 23.

[0069] Optionally, the water pump assembly 70 is sandwiched between the chassis 21 and the upper shell 22, and the water pump assembly 70 is also connected to the collection space 13 of the waste collection device. In one specific embodiment, the opening 121 of the side wall 12 is provided facing the water pump assembly 70, and the water flowing out of the opening 121 through the filter unit 122 can be discharged from the outlet 23 under the suction of the water pump assembly 70.

[0070] In some other embodiments, the water pump assembly 70 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.

[0071] With this configuration, the water pump assembly 70 is located inside the body 20, which can draw water from the suction port 111, filter it through the garbage collection assembly 10, and then spray it out through the water outlet 23, thereby achieving automatic cleaning of the travel surface.

[0072] In one implementation, such as Figure 5 As shown, the body 20 includes a blocking part 24, which is used to connect with the bottom wall 11 of the garbage collection assembly 10 and enclose to form an isolation cavity 25. The suction port 111 and the isolation cavity 25 are located on opposite sides of the blocking part 24, and the magnetic sensing element 15 is disposed in the isolation cavity 25.

[0073] Optionally, one end of the blocking portion 24 is connected to the chassis 21, and the other end extends toward the waste collection assembly 10 and is used to connect with the bottom wall 11 to form an isolation cavity 25. Optionally, both the extension portion 14 and the mounting portion 17 are located within the isolation cavity 25.

[0074] With this configuration, the isolation chamber 25 and the space containing the suction port 111 are isolated from each other. Unfiltered water flowing from outside the suction port 111 is guided by the connecting wall 114 and the blocking part 24 before entering the collection space 13, instead of flowing directly into the isolation chamber 25. This structural arrangement ensures that the magnetic sensing element 15 is in a relatively closed and clean environment, completely preventing wastewater containing iron filings, gravel, or other metal impurities from contacting the magnetic sensing element 15, thus eliminating the possibility of the magnetic sensing element 15 adsorbing iron filings and other debris at the source. This design not only prevents metal particles such as iron filings from being adsorbed around the magnetic sensing element 15 or onto the side wall 12, reducing the difficulty of cleaning for users, but also ensures a long-term stable magnetic field environment, preventing external interference with the signal detected by the magnetic induction sensor 50, thereby significantly improving the accuracy and reliability of in-situ detection of the waste collection assembly 10.
