Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to waste collection devices and cleaning equipment. Background Technology

[0002] With economic development and social progress, people have increasingly higher demands for quality of life, and various cleaning devices have begun to appear in people's lives. Common cleaning devices include vacuum cleaners, robotic vacuum cleaners, and floor scrubbers, among which floor scrubbers are widely used because they combine washing and mopping functions.

[0003] A floor scrubber includes components such as a clean water tank, a water spray system, floor brushes, a motor, and a recycling bin. The water spray system is connected to the clean water tank. When the scrubber is working, the water spray system sprays water, and the floor brushes assist in scrubbing the floor to clean it. The recycling bin contains a filter bag. The motor provides suction to send the mixture (including airflow, wastewater, and dry waste) sucked in by the floor brushes into the filter bag. Dry waste is filtered and collected inside the filter bag, while airflow and wastewater flow out through the mesh of the filter bag. Wastewater remains in the recycling bin, and airflow is then sucked into the motor.

[0004] Typically, after a period of use, users need to remove the filter bag and empty the waste stored inside. However, in related technologies, users are prone to getting their hands dirty when removing the filter bag due to the wastewater adhering to it, resulting in a poor user experience. Summary of the Invention

[0005] Based on this, a garbage collection device and cleaning equipment are provided so that users do not get their hands dirty when removing the filter bag, resulting in a better user experience.

[0006] A waste collection device, comprising:

[0007] The recycling bin has a recycling chamber with an air inlet for communicating with the outlet of the floor brush and an air outlet for communicating with the suction inlet of the motor.

[0008] A filter assembly is installed inside the recycling chamber. The filter assembly includes a filter bag and a handle that are fixedly connected. The filter bag has an inner cavity for containing waste and a bag opening that communicates with the inner cavity. The bag opening communicates with the air inlet.

[0009] A mounting bracket is located inside the recovery chamber and connected to the chamber wall. The filter bag is connected to the mounting bracket. The recovery chamber includes an isolation space formed by the mounting bracket. The filter bag is located outside the isolation space. The bag inlet flow path passes through the isolation space. The handle is located in the isolation space and outside the bag inlet flow path. The bag inlet flow path is the path through which the inhaled material sucked in by the floor brush flows into the inner chamber from the air inlet.

[0010] In one embodiment, the recycling chamber is provided with a conduit located on the bag inlet flow path, the bag opening and the air inlet are connected through the conduit, and the handle is located on the outside of the conduit.

[0011] In one embodiment, the filter assembly includes a filter cover fixedly installed at the bag opening, the filter cover having a notch communicating with the bag opening, the notch communicating with the air inlet via the conduit, and the handle being fixedly connected to the filter cover.

[0012] In one embodiment, the bag opening is located at one end of the filter bag opposite to the bottom wall of the recycling chamber along the depth direction of the recycling chamber, and the handle protrudes from the filter cover toward the side opposite to the filter bag.

[0013] In one embodiment, the filter cover is provided with two handles, and the two handles are symmetrically arranged about the notch.

[0014] In one embodiment, the waste collection device includes a water level detection component, a chamber body, and a chamber cover. The chamber cover is detachably connected to one end of the chamber body away from the bottom wall of the recycling chamber along the depth direction. The chamber body and the chamber cover define the recycling chamber. A conduit is connected to the chamber cover, and a filter bag is connected to the chamber body. The water level detection component includes a probe connected to the chamber body and a connecting terminal connected to the chamber cover. The probe is in contact with and electrically connected to the connecting terminal. The connecting terminal and one end of the probe near the connecting terminal are located outside the conduit.

[0015] In one embodiment, the waste collection device includes a mounting frame located within the recycling chamber and connected to the chamber wall, a filter bag connected to the mounting frame, one end of a probe passing through the mounting frame along the depth direction protruding from the mounting frame toward the connecting terminal, and the other end protruding from the mounting frame toward the bottom wall of the recycling chamber, and the connecting terminal extending from the cover toward the probe.

[0016] In one embodiment, the connecting terminal is connected to the compartment cover by an elastic element, and the probe elastically abuts against the connecting terminal.

[0017] In one embodiment, the waste collection device includes a limiting member connected to the mounting frame, the limiting member having a mounting cavity and a communicating hole, the mounting cavity being connected to the recycling cavity through the communicating hole, and the filter bag extending at least partially into the mounting cavity.

[0018] In one embodiment, the limiting member extends along the depth direction, and one end of the limiting member opposite to the bottom wall of the recycling chamber along the depth direction has an installation port, the filter cover covers the installation port, and the filter bag extends into the mounting chamber through the installation port.

[0019] In one embodiment, one end of the filter bag near the bag opening is connected to the limiting member.

[0020] In one embodiment, the filter assembly includes a suspension ring connected to one end of the filter bag near the bag opening. The suspension ring extends from the bag opening in a first direction toward a side opposite to the inner cavity. The suspension ring is fixedly connected to the filter cover along its own thickness direction on one side. The filter cover abuts against the limiting member via the suspension ring along its own thickness direction away from the filter cover, so that the limiting member abuts against the mounting bracket. The first direction is perpendicular to the depth direction.

[0021] In one embodiment, the limiting member includes a limiting body and a connecting plate. The limiting body surrounds the mounting cavity. The connecting plate is connected to one end of the limiting body near the mounting opening along the depth direction. The connecting plate extends from the limiting body along the first direction toward the side opposite to the mounting cavity. The filter cover abuts against the connecting plate through the suspension ring, so that the connecting plate abuts against the mounting bracket.

[0022] In one embodiment, the mounting bracket includes a baffle extending along the depth direction, the recovery chamber includes a first space located on one side of the baffle along its own thickness direction, and a second space located on the other side, the first space, the second space, and the air outlet being sequentially connected, and the limiting member being installed in the first space.

[0023] In one embodiment, the mounting frame further includes a base plate, a top plate, and a side plate. The top plate and the base plate are spaced apart along the depth direction. The baffle is connected to the base plate and the top plate. The side plate, extending along the depth direction, extends from the top plate toward the base plate. Both the side plate and the base plate abut against the cavity wall of the recovery chamber. There is a gap between the baffle and the cavity wall of the recovery chamber. The base plate is provided with a through hole. The connecting plate can abut against the top plate. The limiting body extends between the baffle, the base plate, and the side plate.

[0024] In one embodiment, the filter cover is snapped into the limiting member, and the filter bag is clamped between the filter cover and the limiting member at one end near the bag opening.

[0025] In one embodiment, along the depth direction, the conduit is located on the side of the filter cover opposite to the filter bag, the conduit extends along a first direction, the conduit has a first opening aligned with and communicating with the air inlet, and a second opening aligned with and communicating with the notch, the first opening being located on the side wall of the conduit along the first direction near the air inlet, and the second opening being located on the end wall of the conduit along the depth direction near the filter bag, wherein the first direction is perpendicular to the depth direction.

[0026] In one embodiment, the waste collection device further includes a recycling pipe located outside the recycling bin, one end of which is aligned with and connected to the first opening, and the other end of which is connected to the discharge outlet.

[0027] In one embodiment, the recovery chamber is provided with a defoaming element, and the airflow flowing out of the filter bag flows through the defoaming element to the air outlet.

[0028] In one embodiment, the defoaming element is located outside the suction range of the motor, wherein the suction range is the range within which the motor can draw in liquid.

[0029] In one embodiment, the waste collection device includes a mounting frame located inside the recycling chamber and connected to the chamber wall, a filter bag connected to the mounting frame, the mounting frame having a mounting groove, and a foam-reducing component being a sponge, the sponge being larger than the size of the mounting groove, and the sponge being interference-fitted with the groove wall of the mounting groove.

[0030] The aforementioned waste collection device includes a filter assembly installed within the recycling chamber, comprising a connected filter bag and a handle. The filter bag's opening connects to an air inlet, which in turn connects to the exhaust outlet of the floor brush. The exhaust outlet connects to the motor's intake port. Therefore, when the motor provides suction, the material drawn in by the floor brush (including airflow, wastewater, and dry waste) is drawn into the filter bag's inner cavity through the air inlet. Dry waste is filtered and retained within the filter bag, while airflow and wastewater flow out through the filter bag's mesh. Wastewater sinks under gravity and remains within the recycling chamber, while airflow exits through the exhaust outlet. Since the filter bag is fixedly connected to the handle, users can remove it from the recycling chamber by lifting the handle when emptying the waste. The recycling chamber includes an isolated space divided by the mounting bracket. The bag inlet flow path is the path through which the inhaled material flows into the inner chamber from the air inlet. The filter bag is located outside the isolated space, and the bag inlet flow path passes through the isolated space. The handle is located in the isolated space and outside the bag inlet flow path. Therefore, the inhaled material will not pass through the handle during the process of flowing into the inner chamber of the filter bag from the air inlet. The chance of the handle being contaminated by sewage and garbage is greatly reduced. As a result, users are less likely to get their hands dirty when taking out the filter bag by lifting the handle, resulting in a better user experience.

[0031] A cleaning device includes the aforementioned garbage collection device, and further includes the motor and the floor brush, wherein the outlet of the floor brush is connected to the air inlet, and the suction inlet of the motor is connected to the air outlet.

[0032] The aforementioned cleaning equipment, by applying the aforementioned waste collection device, makes it easier for users to remove the filter bag without getting their hands dirty, resulting in a better user experience. Attached Figure Description

[0059] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0060] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not 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 application.

[0061] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0062] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0063] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0064] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0065] See Figure 1 The cleaning equipment provided in this application is a floor scrubber, which includes components such as a dust collection device 10, a floor brush 20, a pole 30, a handle 40, a body 50, and a battery pack 60. The floor brush 20 is installed at one end of the pole 30 along its length, and the handle 40 is installed at the other end of the pole 30. The dust collection device 10, the body 50, and the battery pack 60 are arranged along the length of the pole 30 and are all mounted on the pole 30. A motor is installed inside the body 50 to provide suction power, the battery pack 60 powers the motor and other components, and the handle 40 is for the user to hold.

[0066] See Figure 1 and Figure 3 The garbage collection device 10 has an air inlet 131 for airflow and an air outlet 132 for airflow. The exhaust outlet of the floor brush 20 is connected to the air inlet 131, and the suction inlet of the motor is connected to the air outlet 132. When the cleaning equipment is working, the suction material sucked in by the floor brush 20 includes airflow and dirt (dirt includes dry garbage and sewage). The dirt is carried by the airflow from the air inlet 131 into the garbage collection device 10, and finally the dirt is retained in the garbage collection device 10. The airflow flows from the air outlet 132 through the motor and is discharged.

[0067] See Figure 2 , Figure 5 , Figure 11 and Figure 13In some embodiments, the waste collection device 10 includes a recycling bin 100, a mounting frame 400, and a filter assembly. The recycling bin 100 has a recycling chamber 130, which has the aforementioned air inlet 131 and air outlet 132. The filter assembly is installed within the recycling chamber 130 and includes a filter bag 210 and a handle 240 fixedly connected together. The filter bag 210 has an inner cavity 211 for containing waste and a bag opening 2111 communicating with the inner cavity 211, which is connected to the air inlet 131. See also... Figure 4 , Figure 11 and Figure 15 The mounting bracket 400 is located inside the recovery chamber 130 and connected to the chamber wall of the recovery chamber 130. The filter bag 210 is connected to the mounting bracket 400. The recovery chamber 130 includes an isolation space 1341 formed by the mounting bracket 400. The filter bag 210 is located outside the isolation space 1341. The bag inlet flow path passes through the isolation space 1341. The handle 240 is located in the isolation space 1341 and outside the bag inlet flow path. The bag inlet flow path is the path through which the inhaled material sucked in by the floor brush 20 flows into the inner chamber 211 from the air inlet 131.

[0068] In the aforementioned waste collection device 10, the opening 2111 of the filter bag 210 is connected to the air inlet 131, which is connected to the outlet of the floor brush 20. The air outlet 132 is connected to the suction port of the motor. Therefore, when the motor provides suction, the material sucked in by the floor brush 20 (including airflow, sewage, and dry waste) can be drawn into the inner cavity 211 of the filter bag 210 through the air inlet 131. Dry waste will be filtered and retained inside the filter bag 210, while airflow and sewage will flow out through the mesh of the filter bag 210. Sewage will sink under gravity and remain in the recycling chamber 130, and airflow will flow out through the air outlet 132 of the recycling chamber 130. The filter bag 210 is fixedly connected to the handle 240. When it is necessary to remove the filter bag 210 to empty the waste, the user can lift the handle 240 to remove the filter bag 210 from the recycling chamber 130. The recycling chamber 130 includes an isolation space 1341 formed by the mounting bracket 400. The bag inlet flow path is the path through which the inhaled material flows from the air inlet 131 into the inner chamber 211. The filter bag 210 is located outside the isolation space 1341, and the bag inlet flow path passes through the isolation space 1341. The handle 240 is located in the isolation space 1341 and outside the bag inlet flow path. Therefore, the inhaled material will not pass through the handle 240 during its flow from the air inlet 131 into the inner chamber 211 of the filter bag 210, greatly reducing the chance of the handle 240 being contaminated by sewage and garbage. During the airflow outflow, since the airflow is already relatively clean, even if it touches the handle 240, it will not contaminate the handle 240. Therefore, users are less likely to get their hands dirty when removing the filter bag 210 by lifting the handle 240, resulting in a better user experience.

[0069] See Figure 5 , Figure 11 and Figure 13 Specifically, in some embodiments, the recycling chamber 130 is provided with a conduit 500 located in the bag inlet flow path, the bag opening 2111 and the air inlet 131 are connected by the conduit 500, and the handle 240 is located on the outside of the conduit 500.

[0070] Specifically, the conduit 500 is also located within the isolation space 1341, forming the aforementioned bag inlet flow path. Since the bag opening 2111 and the air inlet 131 are connected via the conduit 500, dirt and airflow flow into the filter bag 210 through the conduit 500. The handle 240 is located outside the conduit 500; therefore, dirt will not come into contact with the handle 240 during its flow through the conduit 500. When the user lifts the handle 240 to remove the filter bag 210, their hands will not become dirty.

[0071] See Figure 5 , Figure 9 and Figure 13 Furthermore, in some embodiments, the filter assembly includes a filter cover 230 fixedly installed at the bag opening 2111. The filter cover 230 has a notch 231 communicating with the bag opening 2111. The notch 231 is connected to the air inlet 131 through a conduit 500. A handle 240 is fixedly connected to the filter cover 230.

[0072] Since the filter bag 210 is a flexible bag, a filter cover 230 is fixedly connected to it to facilitate installation. Dirt and airflow flow in through the conduit 500, pass through the notch 231 to the bag opening 2111, and then flow into the filter bag 210. A handle 240 is fixedly connected to the filter cover 230, allowing the filter cover 230 and filter bag 210 to be removed together by lifting the handle 240. The handle 240 can be integrally formed with the filter cover 230, or the two can be fixed together by welding or other methods.

[0073] Furthermore, the bag opening 2111 is located on the filter bag 210 at one end away from the bottom wall of the recovery chamber 130 along the depth direction of the recovery chamber 130, and the handle 240 protrudes from the filter cover 230 toward the side away from the filter bag 210.

[0074] Specifically, from the perspective of the attached drawing, the bag opening 2111 is located at the upper end of the filter bag 210, and the filter bag 210 is fixedly installed at the lower end of the filter cover 230. The handle protrudes upward from the top surface of the filter cover 230.

[0075] See Figure 5 and Figure 9 Preferably, in some embodiments, two handles 240 are symmetrically arranged on the filter cover 230 about the notch 231.

[0076] Specifically, two handles 240 are symmetrically positioned at the edges of the filter cover 230, and the guide tube 500 is located between the two handles 240. Users can simultaneously pull both handles 240 to remove the filter cover 230 and the filter bag 210, making the operation more stable.

[0077] See Figure 2 , Figure 6 and Figure 11 In some embodiments, the waste collection device 10 includes a water level detection component, a bin body 110, and a bin cover 120. The bin cover 120 is detachably connected to one end of the bin body 110 away from the bottom wall of the recycling chamber 130 along the depth direction of the recycling chamber 130. The bin body 110 and the bin cover 120 define the recycling chamber 130. A conduit 500 is connected to the bin cover 120, and a filter bag 210 is connected to the bin body 110. See also... Figure 4 , Figure 13 and Figure 14 The water level detection assembly includes a probe 710 connected to the tank body 110 and a connection terminal 720 connected to the tank cover 120. The probe 710 is in contact with and electrically connected to the connection terminal 720. The connection terminal 720 and the end of the probe 710 near the connection terminal 720 are located outside the conduit 500.

[0078] Specifically, from the perspective of the attached drawings, the chamber cover 120 is detachably connected to the upper end of the chamber body 110, and the two can be detachably installed through conventional methods such as snap-fit. The conduit 500 extends from the chamber cover 120 toward the chamber body 110. Preferably, the conduit 500 and the chamber cover 120 are integrally formed. The filter assembly is located inside the chamber body 110. The aforementioned air inlet 131 is located on the side wall of the chamber body 110 along the first direction, and the air outlet 132 is located on the chamber cover 120. A HEPA filter 121 is installed at the air outlet 132 to further filter the outgoing airflow, ensuring the cleanliness of the airflow flowing into the motor. Both the connecting terminal 720 and the probe 710 extend vertically. The lower end of the probe 710 can extend into the water for detecting the water level, and the upper end of the probe 710 is used to contact and electrically connect with the connecting terminal 720 to transmit signals to the connecting terminal 720. The end of the probe 710 closest to the connection terminal 720 is the upper end of the probe 710. With both the upper end of the probe 710 and the connection terminal 720 located outside the conduit 500, dirt will not come into contact with the connection area between the probe 710 and the connection terminal 720 during the flow of dirt through the conduit 500. This reduces the chance of water entering the area and thus reduces the probability of short circuit in the connection area.

[0079] Furthermore, compared to the method of setting the entire water level detection component on the tank cover 120 and extending it into the tank body 110 from the tank cover 120, in this embodiment, since the connecting terminal 720 and the probe 710 are set separately, it is more convenient to install the tank cover 120. It is only necessary to make the connecting terminal 720 and the probe 710 contact each other.

[0080] It should be noted that, from the perspective shown in the attached figures, the vertical direction is the depth direction of the recovery chamber 130, which is also the length direction of the rod 30, and the direction perpendicular to the vertical direction is the first direction. All depth directions mentioned in this article refer to the depth direction of the recovery chamber 130.

[0081] See Figure 11 and Figure 13 In some embodiments, along the depth direction of the recovery chamber 130, the conduit 500 is located on the side of the filter cover 230 opposite to the filter bag 210. The conduit 500 extends along a first direction and has a first opening 510 aligned with and communicating with the air inlet 131, and a second opening 520 aligned with and communicating with the notch 231. The first opening 510 is located on the side wall of the conduit 500 along the first direction near the air inlet 131, and the second opening 520 is located on the end wall of the conduit 500 along the depth direction of the recovery chamber 130 near the filter bag 210.

[0082] Specifically, from the perspective of the attached drawings, the air inlet 131 is located above the notch 231 in the vertical direction. The duct 500 is located entirely above the filter cover 230 and has a regular shape extending along the first direction, which facilitates manufacturing and installation. When the chamber body 110 and the chamber cover 120 are connected, the duct 500 abuts against the filter cover 230, and the second opening 520 is aligned with and connected to the notch 231, realizing the connection between the air inlet 131 and the bag opening 2111. When the chamber cover 120 is separated from the chamber body 110, the duct 500 also separates from the filter cover 230.

[0083] In other embodiments, the duct 500 can also be configured with other shapes and positions, simply adjusted according to the positions of the air inlet 131 and the notch 231. For example, see... Figure 15 and Figure 16 The catheter 500 includes a first segment 530 extending along a first direction and a second segment 540 extending along the depth direction of the recovery chamber 130. The first segment 530 and the second segment 540 are connected, and the first segment 530 is provided with a first opening 510 at one end away from the second segment 540, and the second segment 540 is provided with a second opening 520 at one end away from the first segment 530.

[0084] Preferably, a second seal 640 is provided between the second opening 520 and the notch 231, and a third seal 650 is provided between the first opening 510 and the air inlet 131 to enhance the sealing of the connection and ensure that dirt and airflow do not leak through the gaps. Preferably, the second seal 640 and the third seal 650 can be integrally molded with the conduit 500 as a single component to simplify the assembly and disassembly process.

[0085] See Figure 5 , Figure 7 , Figure 10 and Figure 13 In some embodiments, one end of the probe 710, which passes through the mounting frame 400 along the depth direction of the recovery chamber 130, protrudes from the mounting frame 400 toward the connection terminal 720, and the other end protrudes from the mounting frame 400 toward the bottom wall of the recovery chamber 130. The connection terminal 720 extends from the cover 120 toward the probe 710.

[0086] Specifically, the mounting frame 400 is located inside the chamber 110, and it is interference-fitted with the side wall of the recovery chamber 130. The filter bag 210 extends into the mounting frame 400. From the perspective of the attached drawings, the mounting frame 400 has a top plate 430 and a bottom plate 420 arranged at intervals in the vertical direction, and both the top plate 430 and the bottom plate 420 extend in a first direction. The mounting frame 400 has an elongated hole 480 extending vertically. A probe 710 passes through the elongated hole 480 vertically. The upper end of the probe 710 protrudes upward above the top plate 430 to facilitate contact and electrical connection with the connecting terminal 720; the lower end of the probe 710 protrudes downward below the bottom plate 420 to facilitate contact with wastewater for water level detection.

[0087] See Figure 5 and Figure 14 Preferably, in some embodiments, the connecting terminal 720 is connected to the cover 120 by an elastic member 730, and the probe 710 elastically abuts against the connecting terminal 720.

[0088] Specifically, the compartment cover 120 has a connection hole 122, and the connection terminal 720 is installed in the connection hole 122. The elastic element 730 is also located in the connection hole 122 and is sleeved on the outside of the connection terminal 720. From the perspective of the attached drawings, when the compartment body 110 is not connected to the compartment cover 120, the lower end of the connection terminal 720 extends beyond the connection hole 122; when the compartment body 110 is connected to the compartment cover 120, the upper end of the probe 710 abuts against the lower end of the connection terminal 720, compressing the elastic element 730, causing the connection terminal 720 to retract into the connection hole 122. In this way, when the probe 710 and the connection terminal 720 come into contact, they elastically abut against each other, avoiding wear caused by hard contact, and also improving the fit during contact.

[0089] See Figure 5 , Figure 8 , Figure 10 and Figure 11 In some embodiments, the waste collection device 10 includes a limiting member 300 connected to the mounting frame 400. The limiting member 300 has a mounting cavity 310 and a communicating hole 320. The mounting cavity 310 is connected to the recycling cavity 130 through the communicating hole 320. The filter bag 210 extends at least partially into the mounting cavity 310.

[0090] Since the filter bag 210 extends at least partially into the mounting cavity 310 of the limiting member 300, the range of motion of the portion of the filter bag 210 extending into the mounting cavity 310 is limited by the limiting member 300. In other words, the limiting member 300 can, to a certain extent, restrict the position of the filter bag 210, preventing it from swinging excessively. Therefore, when the motor provides suction, the filter bag 210 and the dry waste collected inside it are less likely to swing wildly within the recycling chamber 130, thus preventing blockage of the air outlet 132 of the recycling chamber 130. Airflow can then be smooth, and the motor is less likely to malfunction as a result.

[0091] See Figures 10 to 12 In some embodiments, one end of the filter bag 210 near the bag opening 2111 is connected to the mounting bracket 400, and the other end of the filter bag 210 away from the bag opening 2111 extends into the mounting cavity 310.

[0092] Specifically, from the perspective of the attached drawings, the bag opening 2111 of the filter bag 210 is located at its upper end, and the lower end of the filter bag extends into the mounting cavity 310. It is understandable that when the motor starts suction, since the upper end of the filter bag 210 near the bag opening 2111 is connected to the mounting frame 400, and further connected to the recovery chamber 100, the lower end away from the bag opening 2111 will experience the greatest swing amplitude. Therefore, extending the lower end away from the bag opening 2111 into the mounting cavity 310 can more effectively limit the swing of the filter bag 210. Of course, in other embodiments, the filter bag 210 can also pass through the mounting cavity 310, so that both the upper end near the bag opening 2111 and the lower end away from the bag opening 2111 are exposed outside the mounting cavity 310, with the area between these two ends contained within the mounting cavity 310.

[0093] See Figures 10 to 12 Preferably, in some embodiments, the filter bag 210 extends completely into the mounting cavity 310. In this way, the swing of the filter bag 210 will be completely restricted by the limiting member 300, resulting in a better limiting effect.

[0094] See Figures 10 to 12 In some embodiments, the limiting member 300 extends along the depth direction of the recovery chamber 130, and the end of the limiting member 300 away from the bottom wall of the recovery chamber 130 along the depth direction of the recovery chamber 130 has an installation port 311, the filter cover 230 covers the installation port 311, and the filter bag 210 extends into the installation chamber 310 through the installation port 311.

[0095] Specifically, from the perspective of the accompanying drawings, the limiting member 300 extends vertically, and its upper end has a mounting opening 311 communicating with the mounting cavity 310. The filter bag 210 can extend downward into the mounting cavity 310 from the mounting opening 311. The size of the filter cover 230 matches the mounting opening 311, and it can cover the mounting opening 311. The cross-section of the mounting cavity 310 in the vertical direction is elliptical. Of course, in other embodiments, the limiting member 300 can also be set to other shapes and arrangements. For example, the cross-section of the mounting cavity 310 in the vertical direction can also be circular or polygonal, as long as it can limit the swing of the filter bag 210.

[0096] See Figure 8 In some embodiments, the limiting member 300 has a plurality of connecting holes 320 on the bottom wall opposite to the mounting port 311 along the depth direction of the recovery cavity 130 and on the side wall along the first direction.

[0097] Specifically, the connecting holes 320 can be elongated, elliptical, circular, polygonal, or other shapes. Multiple connecting holes 320 are evenly arranged, and the limiting member 300 is entirely perforated. Airflow and wastewater exiting through the mesh of the filter bag 210 can flow out through each connecting hole 320, thus making the outflow process smoother.

[0098] See Figures 10 to 12 In some embodiments, when the chamber body 110 is connected to the chamber cover 120, one end of the filter bag 210 near the bag opening 2111 is connected to the limiting member 300. Specifically, from the perspective of the accompanying drawings, the upper end of the filter bag 210 is detachably connected to the upper end of the limiting member 200, and the limiting member 200 is detachably connected to the mounting bracket 400.

[0099] See Figure 8 , Figure 9 and Figure 12 Furthermore, in some embodiments, the filter assembly includes a suspension ring 220 connected to one end of the filter bag 210 near the bag opening 2111. The suspension ring 220 extends from the bag opening 2111 in a first direction toward the side opposite to the inner cavity 211. The suspension ring 220 is fixedly connected to the filter cover 230 along its own thickness direction. The filter cover 230 can abut against the limiting member 300 through the side of the suspension ring 220 away from the filter cover 230 along its own thickness direction, so that the limiting member 300 abuts against the mounting bracket 400.

[0100] Specifically, from the perspective of the attached drawings, the suspension ring 220 is annular and surrounds the outer side of the bag opening 2111 at the upper end of the filter bag 210. The thickness direction of the suspension ring 220 is the same as the depth direction of the aforementioned recovery chamber 130. The upper end face of the suspension ring 220 is fixedly connected to the lower end face of the filter cover 230, and the filter cover 230 can abut against the limiting member 300 through the lower end face of the suspension ring 220, so as to suspend the filter bag 210 connected to the suspension ring 220 in the mounting cavity 310.

[0101] The top plate 430 of the mounting bracket 400 is provided with a mounting hole 431, and the limiting member 300 extends downward into the mounting bracket 400 through the mounting hole 431. The filter cover 230 can abut against the limiting member 300 through the suspension ring 220, so that the limiting member 300 abuts against the top plate 430, thereby suspending the limiting member 300 and the filter bag 210 inside the mounting bracket 400.

[0102] Preferably, the hanging ring 220 and the filter bag 210 are made of the same material and are integrally formed. The opening of a bag with mesh can be folded outwards to form the hanging ring 220. Specifically, both are made of white PP non-woven fabric or white PA mesh with a mesh size of 30 mesh.

[0103] In other embodiments, the suspension ring 220 can also be made of rigid plastic or other materials. In this way, the filter bag 210 can be installed directly through the rigid suspension ring 220 without the need for a filter cover 230.

[0104] In some embodiments, the suspension ring 220 is fixed to the filter cover 230 by ultrasonic welding.

[0105] In some embodiments, the limiting member 300 is made of transparent ABS.

[0106] See Figure 8 , Figure 9 and Figure 12 In other embodiments, the suspension ring 220 can be removed, and the filter bag 210 near the bag opening 2111 can be directly clamped between the filter cover 230 and the limiting member 300. This reduces a component, lowers costs, and allows users to directly purchase common filter bags for replacement, increasing versatility. Specifically, the filter cover 230 and the limiting member 300 can be fixed by snap-fit, clamping the filter bag 210 near the bag opening 2111 between them. For example, a locking block can be provided on the filter cover 230, and a locking groove can be provided on the limiting member 300, with the locking block engaging the locking groove. Alternatively, the positions of the locking block and the locking groove can be interchanged.

[0107] See Figure 8 , Figures 10 to 12Furthermore, in some embodiments, the limiting member 300 includes a limiting body 330 and a connecting plate 340. The limiting body 330 surrounds the mounting cavity 310. The connecting plate 340 is connected to one end of the limiting body 330 near the mounting opening 311 along the depth direction of the recovery cavity 130. The connecting plate 340 extends from the limiting body 330 in a first direction toward the side away from the mounting cavity 310. The filter cover 230 can abut against the connecting plate 340 through the suspension ring 220 so that the connecting plate 340 abuts against the mounting frame 400.

[0108] Specifically, the limiting member 300 is similar in shape to the open filter bag 210. The bottom and side walls of the limiting body 330 form an installation cavity 310. The connecting plate 340 is annular and surrounds the outside of the installation opening 311 at the upper end of the limiting body 330. The filter bag 210 extends into the limiting body 330, and the suspension ring 220 is suspended from the connecting plate 340. The filter cover 230 abuts against the connecting plate 340 through the suspension ring 220, so that the connecting plate 340 abuts against the top plate 430 of the mounting bracket 400.

[0109] See Figure 12 Preferably, an "L"-shaped first sealing element 630 is provided between the connecting plate 340 and the top plate 430 to protect the connecting plate 340 and the top plate 430 from being crushed. The filter cover 230 abuts against the connecting plate 340 through the suspension ring 220, so that the connecting plate 340 abuts against the first sealing element 630, and then against the top plate 430 of the mounting bracket 400.

[0110] See Figure 5 , Figure 7 and Figure 11 Furthermore, in some embodiments, the mounting bracket 400 includes a baffle 410 extending along the depth direction of the recovery chamber 130. The recovery chamber 130 includes a first space 133 located on one side of the baffle 410 along its own thickness direction and a second space 134 located on the other side. The first space 133, the second space 134, and the air outlet 132 are connected in sequence, and the limiting member 300 is installed in the first space 133.

[0111] Specifically, the air inlet 131 is located in the first space 133; the air outlet 132 is partially located in the second space 134 and partially in the first space 133, but the air outlet 132 only communicates with the second space 134 and not with the first space 133. The baffle 410 is an arc-shaped plate; in other embodiments, the baffle 410 can also be a straight plate. There is a gap between the baffle 410 and the cavity sidewall of the recovery chamber 130, through which the first space 133 and the second space 134 located on both sides of the baffle 410 can communicate. The limiting member 300 and the filter assembly are both located in the first space 133, and the airflow flowing out of the filter bag 210 finally flows to the second space 134 and flows out from the second space 134 toward the air outlet 132. In the above embodiment, the filter bag 210 and the air inlet 131 are located in the first space 133, and the air outlet 132 is connected to the second space 134, rather than directly connected to the air inlet 131 or the first space 133. Therefore, the airflow has a longer path from the air inlet 131 to the air outlet 132 and can stay in the recovery chamber 130 for a longer time, so that the dirt can be fully filtered by the filter bag 210 and the filtration effect is better.

[0112] See Figure 5 , Figure 7 and Figure 12 Furthermore, in some embodiments, the mounting frame 400 also includes a side plate 440, a baffle 410 connected to the bottom plate 420 and the top plate 430, the side plate 440 extending along the depth direction of the recovery chamber 130 extending from the top plate 430 toward the bottom plate 420, the side plate 440 and the bottom plate 420 both abutting against the cavity wall of the recovery chamber 130, the bottom plate 420 is provided with a through hole, and the limiting body 330 extends into the space between the baffle 410, the bottom plate 420 and the side plate 440.

[0113] Specifically, from the perspective of the attached drawings, the top plate 430 is connected to the top of the baffle 410, and the bottom plate 420 is connected to the bottom of the baffle 410. The top surface of the top plate 430 also has an upwardly extending vertical plate 460, which surrounds the outside of the mounting hole 431. The filter cover 230, the filter bag 210, and the limiting member 300 are all accommodated in the area inside the vertical plate 460. The area on the top plate 430 located inside the vertical plate 460 is used to suspend the limiting member 300 and the filter bag 210. The side plate 440 is arc-shaped, matching the shape and size of the sidewall of the recovery chamber 130, thus enabling it to abut against the sidewall of the recovery chamber 130. The outer edge of the bottom plate 420 is arc-shaped, matching the shape and size of the sidewall of the recovery chamber 130, thus enabling it to abut against the sidewall of the recovery chamber 130. The base plate 420 is provided with a first through hole 421 and a second through hole 422. The first through hole 421 is located in the first space 133, and the second through hole 422 is located in the second space 134. Wastewater flowing out of the filter bag 210 can flow through the first through hole 421 under the action of gravity and be stored in the space under the base plate 420. The second through hole 422 is used to achieve air pressure balance. Of the airflow flowing out of the filter bag 210, part flows through the first through hole 421 to the space under the base plate 420, and then flows into the second space 134 through the second through hole 422. The other part flows directly into the second space 134 from the gap between the baffle 410 and the cavity sidewall of the recovery chamber 130.

[0114] The edge of the base plate 420 is also connected to an upwardly extending first extension plate 471. A second extension plate 472, substantially parallel to the base plate 420, is connected around the upper edge of the first extension plate 471. Both the base plate 420 and the second extension plate 472 abut against the sidewall of the recovery chamber 130. The base plate 420, the first extension plate 471, and the second extension plate 472 form a groove 473. A fourth sealing element 660 is inserted into the groove 473 to enhance the seal between the base plate 420, the first extension plate 471, and the sidewall of the recovery chamber 130. The limiting body 330 extends into the space between the second extension plate 472, the first extension plate 471, the base plate 420, the baffle 410, the top plate 430, and the side plate 440.

[0115] In the embodiment shown in the attached drawings, the first space 133 is open on the side opposite to the second space 134, and the lower end of the side plate 440 does not extend to connect with the second extension plate 472. In other embodiments, the lower end of the side plate 440 may also extend to connect with the second extension plate 472.

[0116] See Figure 5In some embodiments, a duckbill valve 620 is provided at the first through hole 421. Under the impact of water flow, the duckbill valve 620 can open, allowing sewage to flow towards the underside of the base plate 420. When there is no water flow impact, the duckbill valve 620 automatically closes, preventing sewage from flowing back upwards from the underside of the base plate 420. It should be noted that although a second through hole 422 is also provided on the base plate 420, because the first through hole 421 is located on the side closer to the ground and the second through hole 422 is located on the side away from the ground during the use of the cleaning equipment, sewage on the underside of the base plate 420 is not easily backflowed through the second through hole 422.

[0117] See Figure 5 , Figure 7 and Figure 12 In other embodiments, the limiting member 300 and the mounting member 400 can also be integrally formed as a single component to simplify the assembly and disassembly process. Specifically, this embodiment is equivalent to... Figure 12 Based on the illustrated embodiment, the bottom wall of the limiting body 330 in the limiting member 300 is removed, and the side wall of the limiting body 330 is extended downwards to be integrated with the base plate 420 in the mounting member 400. At this time, the duckbill valve 620 can be eliminated, and several through holes can be directly provided on the base plate 420 to connect the space above and below the base plate 420, so that sewage can flow through these through holes to the area below the base plate 420.

[0118] See Figure 5 , Figure 7 and Figure 10 In some embodiments, the recovery chamber 130 is provided with a defoaming element 610, and the airflow flowing out of the filter bag 210 flows through the defoaming element 610 to the air outlet 132.

[0119] If detergent is added during the use of the floor scrubber, foam may be present in the sucked-in wastewater. Because foam is light, even if the foam exceeds the upper limit water level, the water level sensor in the recovery chamber 130 may not be able to accurately detect and trigger an alarm. Therefore, foam may be sucked into the motor, potentially causing motor malfunction. In this embodiment, by incorporating an anti-foaming component 610, after the wastewater is discharged from the filter bag 210 and remains in the recovery chamber 130, if foam floats on the surface of the wastewater, the anti-foaming component 610 will absorb the foam as the water level gradually rises until it contacts the foam. This reduces the risk of foam being sucked into the motor along with the airflow when it approaches the air outlet 132, thus preventing motor malfunction.

[0120] See Figure 5 , Figure 7 , Figure 10 and Figure 11In some embodiments, the baffle 410 is provided with a plurality of hollow mounting plates 450 extending toward the second space 134 and abutting against the cavity wall of the recovery cavity 130. The plurality of mounting plates 450 surround the mounting groove 451, and the defoaming component 610 is engaged in the mounting groove 451.

[0121] Specifically, the mounting plate 450 has multiple holes and is hollow in shape, allowing airflow and wastewater to flow through these holes. The shape and size of the end of the mounting plate 450 facing away from the baffle 410 match the sidewall of the recovery chamber 130, so that the edge of the mounting plate 450 can abut against the sidewall of the recovery chamber 130. The side of the mounting groove 451 facing away from the baffle 410 is open, allowing the defoaming component 610 to be inserted into the mounting groove 451 for installation.

[0122] In some embodiments, the defoaming element 610 is a sponge, which can block and absorb foam through its porous material.

[0123] In some embodiments, the size of the sponge is larger than the size of the mounting groove 451, and the sponge is interference-fitted with the groove wall of the mounting groove 451. In other embodiments, other porous materials may be used to make the defoaming component 610.

[0124] Specifically, the defoaming component 610 has a certain degree of elasticity. Therefore, it is only necessary to set a mounting groove 451 with a size slightly smaller than that of the defoaming component 610, so that the fixation can be completed by the rebound force of the defoaming component 610. The fixing structure and installation method are relatively simple.

[0125] Understandably, since the airflow exits the recovery chamber 130 through the air outlet 132 and flows into the motor's suction port, when the motor is working, the closer the foam is to the air outlet 132, the easier it is to be sucked into the motor. Therefore, the risk area for foam to be sucked into the motor is mainly the end area near the air outlet 132 in the direction of airflow outward. Placing the foam defoaming component 610 closer to the air outlet 134 in the second space 134 can more accurately solve the problem of foam being easily sucked in.

[0126] See Figure 11 In some embodiments, the defoaming element 610 is located outside the suction range of the motor, wherein the suction range is the range in which the motor can draw in liquid.

[0127] As mentioned earlier, placing the defoaming component 610 closer to the air outlet 134 in the second space 134 can more accurately solve the problem of foam being easily sucked in. Furthermore, within the second space 134, the defoaming component 610 is positioned further away from the air outlet 132, ensuring it is outside the motor's suction range. Because the defoaming component 610 is outside the motor's suction range, foam is absorbed by it at a greater distance from the air outlet 132, allowing for earlier foam adsorption and further improving safety.

[0128] Furthermore, the distance between the center of the defoaming component 610 and the air outlet 132 in the vertical direction is not greater than a preset length, and the preset length s is in the range of 90mm≤s≤110mm.

[0129] See Figure 10 and Figure 11 In some embodiments, the recovery chamber 130 is provided with a plurality of defoaming elements 610 arranged along the depth direction.

[0130] Specifically, from the perspective of the accompanying drawings, the recovery chamber 130 is provided with multiple defoaming components 610 arranged vertically. For example, in the embodiment shown in the drawings, two defoaming components 610 are provided. By providing multiple defoaming components 610, the adsorption capacity can be enhanced, further reducing the risk of foam being sucked into the motor.

[0131] In some embodiments, the mesh size of the defoaming element 610 is 30 mesh.

[0132] See Figure 4 , Figure 5 , Figure 11 and Figure 15 In some embodiments, the mounting bracket 400 further includes a partition 480, one end of which is connected to the top plate 430 and the other end to the mounting plate 450. The partition 480 extends along the depth direction of the recovery chamber 130. The aforementioned isolation space 1341 is formed by the partition 480, the top plate 430, and the mounting plate 450. The isolation space 1341 is part of the second space 134, specifically, it is located in the end region of the second space 134 near the air outlet 134.

[0133] See Figure 1 and Figure 2 The waste collection device also includes a recycling pipe 800 located outside the recycling bin 100. One end of the recycling pipe 800 is aligned with and connected to the first opening 510 on the conduit 500, and the other end is used to connect to the outlet of the floor brush 20.

[0134] Specifically, the recycling pipe 800 is installed inside the rod body 30, and the recycling chamber 100 is detachably connected to the body 50. Compared with the structure in related technologies where the recycling pipe 800 is built into the recycling chamber 130, in this embodiment, since the recycling pipe 800 is located outside the recycling chamber 100, the internal structure is simpler and the cleaning is more thorough when the recycling chamber 130 is cleaned after the recycling chamber 100 is removed. Furthermore, the volume of the recycling chamber 130 can be used entirely to hold sewage and garbage, resulting in a larger capacity.

[0135] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0136] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
