Description

Technical Field

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

[0002] Most existing cleaning equipment is equipped with a dust collection box to collect garbage, dust, and other dirt generated during cleaning operations. The corresponding base station is equipped with a negative pressure generating device. When the cleaning equipment returns to the base station, the base station uses the negative pressure generated by the negative pressure generating device to suck the dirt out of the dust collection box, thereby achieving automatic cleaning of the dust collection box and ensuring the continuous operation of the cleaning equipment.

[0003] To prevent dirt and grime from leaking from the dust collection box and contaminating the ground, a dust discharge port cover is typically installed at the dust discharge port. When the cleaning equipment is operating normally, the dust discharge port cover is closed to reduce leakage; during base station dust collection, the cover is opened to collect dust. However, existing dust collection boxes often experience clogging of the dust discharge port when collecting dust, thus affecting the dust collection efficiency. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention provides a dust collection box and cleaning equipment to improve the technical problem that the dust discharge port of the existing dust collection box is easily blocked by garbage, which affects the dust collection effect.

[0005] To achieve the above and other related objectives, the first aspect of this utility model provides a dust collection box, which includes: a box body and a dust discharge port cover plate. A dust collection chamber is formed in the box body, and a dust discharge port communicating with the dust collection chamber is provided on the side wall of the box body. The dust discharge port cover plate is movably installed on the box body and can open and close the dust discharge port. The dust discharge port cover plate includes a protrusion, and in response to the dust discharge port cover plate closing the dust discharge port, at least part of the protrusion extends into the dust collection chamber from the dust discharge port.

[0006] The beneficial effects of this design are as follows: By incorporating a protrusion on the dust outlet cover, when the dust outlet is closed, the protrusion extends into the dust collection chamber, disturbing and dispersing the accumulation of waste near the outlet. When the dust outlet cover is open to collect dust, the waste previously accumulated at the outlet becomes loose due to the protrusion being removed, making it easier for the dust collection airflow to carry it out smoothly, thus improving the dust collection efficiency and effectiveness. Simultaneously, because the protrusion extends into the dust collection chamber, it also interferes with the movement trajectory and accumulation position of large pieces of waste near the outlet during operation, altering their accumulation angle and preventing them from densely accumulating near the outlet. This results in a relatively loose accumulation, reducing the probability of large pieces of waste clogging the outlet, further enhancing the dust collection effect and efficiency.

[0007] In one embodiment of the present invention, the protrusion includes a cone, the dust outlet cover includes a shielding surface, the cone includes a bottom surface and a top surface, the bottom surface of the cone is connected to the shielding surface, and the top surface of the cone faces the dust collection chamber.

[0008] The beneficial effects of this design are as follows: By designing the protrusion as a cone structure, the sharp tip of the cone, when extending into the dust collection chamber, can more significantly disturb the garbage accumulation process. This disturbance makes the garbage more loosely packed at the dust discharge port, further reducing the risk of garbage clogging the port and improving dust collection efficiency. Secondly, the cone shape allows garbage in the dust collection chamber to slide along its surface during accumulation, creating a more favorable discharge environment. With the cone's tip facing the dust collection chamber, garbage can smoothly slide into the discharge port when the discharge port cover is opened. This design not only reduces garbage accumulation at the discharge port but also optimizes the discharge path, making it easier for garbage to be discharged from the dust collection chamber and further improving dust collection efficiency.

[0009] In one embodiment of this utility model, the cone is symmetrically arranged along the height direction and / or the width direction of the shielding surface.

[0010] The beneficial effects of this arrangement are that, by symmetrically arranging the cones along the height and / or width of the shielding surface, this layout facilitates mold design and processing, and helps reduce manufacturing costs. Simultaneously, the symmetrical layout allows for more uniform stress distribution on the material during stamping, injection molding, and other molding processes, reducing deformation caused by uneven stress and improving the dimensional consistency of the finished product.

[0011] In one embodiment of the present invention, the cone includes a first cone portion and a second cone portion, the first cone portion and the second cone portion are connected to each other, and a top surface of the cone is formed at the connection position.

[0012] The beneficial effects of this design are as follows: By designing the cone as a combination structure including a first cone and a second cone, the shape, size, or angle of the first and / or second cones can be flexibly adjusted according to different needs, thus achieving diverse cone shape designs. This combined design not only improves the flexibility of cone shape design but also provides a more effective disturbance effect for different types of waste and their accumulation states. This further optimizes the accumulation state of waste within the dust collection chamber, reduces the risk of blockage at the dust outlet during dust collection, and ultimately improves dust collection efficiency.

[0013] In one embodiment of the present invention, the first cone portion and the second cone portion are symmetrically arranged along the width direction of the shielding surface. The first cone portion includes a first inclined surface and a first conical surface that are connected to each other, and the second cone portion includes a second inclined surface and a second conical surface that are connected to each other. The first inclined surface and the second inclined surface are connected to each other, and the first conical surface and the second conical surface are connected to each other.

[0014] The beneficial effects of this design are as follows: When the first and second cone sections are joined, on the one hand, since the first inclined surface can connect with the second inclined surface, a continuous inclined transition structure can be formed at one end of the cone. This structure can generate a relatively uniform disturbance effect during waste accumulation, making the waste easier to slide under the action of the inclined surface, thereby further reducing the accumulation density of waste near the dust discharge port. On the other hand, since the first and second cone sections are joined, a smooth and continuous cone surface structure can be formed at the other end of the cone. This cone surface structure can further improve the accumulation state of the waste, keeping it in a loose accumulation state under the action of the cone surface, thereby further reducing the risk of blockage at the dust discharge port.

[0015] In one embodiment of the present invention, the dust collection chamber includes a bottom wall, and along the height direction of the dust collection chamber, the first conical surface and the second conical surface are located on the side close to the bottom wall, and the first inclined surface and the second inclined surface are located on the side away from the bottom wall.

[0016] The beneficial effects of this design are as follows: The cone can form a near-teardrop shape. Upon entering the dust collection chamber, waste is first guided by the first and second inclined surfaces, making it easier to slide towards the bottom wall. Subsequently, the first and second conical surfaces further agitate the waste near the bottom wall, making the waste accumulation near the bottom wall more loose, thus further reducing the probability of blockage at the dust outlet during dust collection. Furthermore, since larger pieces of waste typically accumulate near the bottom wall, the impact force on the cone is relatively greater on that side. Therefore, positioning the first and second conical surfaces correspondingly on the side near the bottom wall more effectively enhances the support strength and rigidity of the cone near the bottom wall, thereby reducing the probability of damage caused by the greater impact force on that side.

[0017] In one embodiment of the present invention, a support ridge is formed at the docking position of the first inclined surface and the second inclined surface, and the support ridge is inclined relative to the shielding surface.

[0018] The beneficial effects of this design are as follows: by setting a support ridge between the first and second inclined surfaces, not only can the stress concentration at the junction of the first and second inclined surfaces be improved, thus increasing the overall support strength of the cone, but the design of the support ridge can also optimize the manufacturing process of the cone while improving its strength, thereby helping to reduce the manufacturing cost of the cone.

[0019] In one embodiment of this utility model, an intersection line is formed between the supporting edge and the shielding surface, and an intersection point is formed between the connecting line of the first conical surface and the second conical surface and the shielding surface; along the height direction of the shielding surface, the top surface of the cone is located between the intersection line and the intersection point; the minimum distance between the edge of the top surface of the cone and the intersection line is greater than the maximum distance between the edge of the top surface of the cone and the intersection point.

[0020] The beneficial effects of this design are as follows: By positioning the top surface of the cone between the intersection line and the intersection point, and ensuring that the minimum distance between its edge and the intersection line is greater than the maximum distance to the intersection point, the top surface of the cone can be eccentrically positioned close to the bottom wall. With this design, after the waste enters the dust collection chamber, it will be guided by the first and second inclined surfaces, making it easier to slide towards the bottom wall. Simultaneously, because the waste accumulates more densely in the area near the bottom wall of the dust collection chamber, the eccentric design of the cone's top surface allows it to penetrate deeper into this area, achieving a greater insertion depth. This more effectively disturbs the waste near the bottom wall, making the waste accumulation looser and further reducing the risk of clogging the dust outlet.

[0021] In one embodiment of the present invention, the side of the dust outlet cover facing the dust collection chamber includes a shielding surface, and the protrusion includes at least one bending structure. One end of the bending structure is connected to the shielding surface, and the other end bends and extends into the dust collection chamber.

[0022] The beneficial effects of this design are as follows: By incorporating a bent structure on the shielding surface, when the dust outlet cover is in the closed position, the bent structure disperses and disturbs the accumulation of waste near the dust outlet after it enters the dust collection chamber. This disturbance loosens the waste accumulation at the dust outlet, reducing the risk of blockage and improving dust collection efficiency. Furthermore, the waste within the dust collection chamber can slide along the surface of the bent structure during accumulation, creating a more favorable discharge path. This optimizes the waste discharge path, making it easier to remove from the dust collection chamber and further enhancing the dust collection effect.

[0023] In one embodiment of the present invention, the bending structure includes a first bending segment and a second bending segment. One end of the first bending segment is connected to the shielding surface, and the other end is connected to one end of the second bending segment. The other end of the second bending segment is connected to the shielding surface.

[0024] The beneficial effects of this design are as follows: By incorporating the first and second bending sections, their combination creates two bending surfaces. This design, through the synergistic effect of the first and second bending sections, loosens the accumulation of waste within the dust collection chamber, facilitating smooth discharge during subsequent dust collection processes and reducing the risk of blockage at the exhaust port.

[0025] In one embodiment of the present invention, along the height direction of the dust collection chamber, the first bending section is disposed above the second bending section, and the angle between the first bending section and the shielding surface is smaller than the angle between the second bending section and the shielding surface.

[0026] The beneficial effects of this design are as follows: By making the angle between the first bending section and the shielding surface smaller than the angle between the second bending section and the shielding surface, an asymmetrical design of the bending structure is achieved, and the connection point between the first and second bending sections is closer to the bottom wall of the dust collection chamber. When waste enters the dust collection chamber, it is initially guided by the first bending section, making it easier to slide towards the bottom wall. Subsequently, the second bending section further agitates the waste near the bottom wall, making the waste accumulate more loosely near the bottom wall. This allows the waste to be more easily and smoothly extracted from the dust discharge port during dust collection, further reducing the risk of blockage at the dust discharge port.

[0027] In one embodiment of the present invention, the side of the dust outlet cover facing the dust collection chamber includes a shielding surface, and the protrusion includes a plate-shaped body, one end of which is connected to the shielding surface, and the other end extends into the dust collection chamber.

[0028] The beneficial effects of this design are as follows: By placing a plate-like body on the shielding surface, protruding towards the dust discharge port, the plate forms a raised disturbance within the dust collection chamber. This effectively agitates the debris within the chamber, loosening the debris buildup near the dust discharge port and allowing it to slide smoothly out during dust collection, thus reducing the risk of clogging. Furthermore, the simple shape and structure of the plate facilitates its fabrication, reducing manufacturing costs for the protrusion.

[0029] In one embodiment of this utility model, the plate-shaped body is arranged perpendicularly to the shielding surface.

[0030] The advantages of this design are as follows: By positioning the plate perpendicular to the shielding surface, it facilitates the molding and fabrication of the plate on the shielding surface, reducing manufacturing costs. Simultaneously, it allows the plate to more evenly distribute the disturbance caused by the accumulation of waste near the dust outlet, preventing deformation or bending due to uneven stress on both sides of the plate, thus extending its service life.

[0031] In one embodiment of this utility model, the plate-shaped body is arranged parallel to the width direction of the shielding surface or parallel to the height direction of the shielding surface.

[0032] The advantages of this design are as follows: By aligning the plate-like structure parallel to the width and / or height of the shielding surface, the forming process of the plate-like structure on the shielding surface can be further simplified, which helps to further reduce manufacturing costs. Simultaneously, this design allows the plate-like structure to better disperse impact force when subjected to debris, reducing structural damage caused by debris accumulation and extending its service life.

[0065] Please see Figures 1 to 25 This utility model provides a dust collection box 110 and a cleaning device. By providing a protrusion 121 on the dust discharge port cover 120, when the dust discharge port 112 is closed by the dust discharge port cover 120, the protrusion 121 can extend into the dust collection chamber 111, disturbing and dispersing the accumulation of garbage near the dust discharge port 112. Thus, when the dust discharge port cover 120 is opened, the garbage originally accumulated at the dust discharge port 112 will become loose due to the removal of the protrusion 121, making it easier for it to be carried by the dust collection airflow and smoothly discharged from the dust discharge port 112, thereby improving the dust collection efficiency and dust collection effect of the dust collection box 100.

[0066] Please see Figure 1 and Figure 2 This utility model provides a cleaning device, which can be a floor scrubber, a sweeper, a cleaning robot, etc., but is not limited to these. Taking a cleaning robot as an example, in order to perform its cleaning function, the cleaning device includes at least a main body 101 and a dust collection box 110. The dust collection box 110 is installed on the main body 101 to collect and remove dust and debris from the ground during the cleaning operation.

[0067] In some embodiments, the cleaning equipment may also include a wet cleaning device for wet cleaning, which includes a cleaning head, a liquid storage tank, a pump body, and piping components. In other embodiments, the cleaning equipment may also include an intelligent control system, which may integrate multiple functions as needed. These functions may include, but are not limited to, autonomous travel planning based on sensors such as accelerometers, gyroscopes, and odometers; obstacle recognition and collision avoidance based on distance sensors and image recognition devices; autonomous walking based on mechanical mechanisms such as drive wheel sets, driven wheel sets, and drivers; human-computer interaction based on physical buttons, virtual buttons, displays, and indicator lights; energy supply based on rechargeable batteries; and intelligent control based on control circuits or control chips. These will not be elaborated further here.

[0068] Please see Figures 3 to 5 In one embodiment of this utility model, the dust collection box 110 includes a box body 113 and a dust discharge port cover 120. The shape of the box body 113 is not limited, and can be, for example, square, circular, polygonal or other irregular shapes. In this embodiment, the shape of the box body 113 is roughly a horizontally placed polygonal shape, which can be reasonably arranged with other components in the cleaning equipment to achieve a high utilization rate in a limited space.

[0069] Please see Figure 2 and Figure 3 The box body 113 has a dust collection chamber 111 inside, and a dust discharge port 112 communicating with the dust collection chamber 111 is provided on the side wall of the box body 113. The dust discharge port 112 can be provided on the side wall in the width direction of the box body 113 or on the side wall in the length direction of the box body 113; this embodiment does not limit this. Optionally, in this embodiment, please refer to... Figure 4 and Figure 5 The dust outlet 112 is located along the length of the box 113 (e.g., Figure 5 On one side of the wall (as shown in the X1 direction). The dust discharge port cover 120 is movably installed on the housing 113 and can open and close the dust discharge port 112. Figure 4 A schematic diagram showing the dust outlet 112 closed with the dust outlet cover 120. Figure 5 This is a schematic diagram showing the dust outlet cover 120 with the dust outlet 112 open. The dust outlet cover 120 can be movably mounted on the housing 113 in several ways. For example, the dust outlet cover 120 can be rotatably mounted on the housing 113 via a rotating shaft, allowing it to rotate around the shaft to open or close the dust outlet 112. Alternatively, the dust outlet cover 120 can be movably mounted on the housing 113 via a slide rail, allowing it to slide along the rail to open or close the dust outlet 112.

[0070] Specifically, in this embodiment, please refer to Figure 22 and Figure 23 The dust discharge port cover 120 is rotatably mounted on the housing 113 via a rotating shaft 140, and a torsion spring 130 is mounted on the rotating shaft 140. When the dust discharge port cover 120 rotates to open the dust discharge port 112, the torsion spring 130 stores spring force. The spring force stored in the torsion spring 130 can drive the dust discharge port cover 120 to automatically reset and close the dust discharge port 112 after the dust collection process stops.

[0071] Please see Figure 3 The dust discharge port cover 120 includes a protrusion 121. In response to the closure of the dust discharge port 112 by the dust discharge port cover 120, the protrusion 121 extends at least partially from the dust discharge port 112 into the dust collection chamber 111. The number of protrusions 121 is not limited; there can be one or more. Optionally, in this embodiment, one protrusion 121 is provided. This facilitates the manufacturing of the protrusion 121 and helps reduce the manufacturing cost of the dust discharge port cover 120. The shape and structure of the protrusion 121 are also not limited. For example, the protrusion 121 can be a single arc-shaped protrusion structure, a conical protrusion structure, a sheet-like protrusion structure, a plate-like bent protrusion structure, etc., or it can be a combination of multiple protrusion structures, such as a combination of an arc-shaped protrusion and a plate-like protrusion, or a combination of a sheet-like protrusion structure and a plate-like bent protrusion structure, etc. The protrusion 121 may be integrally formed on the dust outlet cover 120, or it may be fixedly connected to the protrusion 121 by bolts, or it may be fixedly connected to the protrusion 121 by adhesive, etc. Optionally, in this embodiment, in order to improve the assembly efficiency of the protrusion 121 and the dust outlet cover 120, the protrusion 121 is integrally formed on the dust outlet cover 120.

[0072] It should be noted that you should refer to [link / reference]. Figure 3 and Figure 4In this embodiment, the dust collection box 110 also includes an exhaust port 115, a dust inlet 114, and a filter element 116. The dust inlet 114 is located on the side wall of the box body 113 and communicates with the dust collection chamber 111. Along the height direction of the box body 113, the exhaust port 115 and the filter element 116 are both located above the dust collection chamber 111, and the exhaust port 115 communicates with the dust collection chamber 111 through the filter element 116. The filter element 116 can be made of various materials, including but not limited to HEPA (High Efficiency Particulate Air) filters, activated carbon filters, polyester fiber filters, or nylon fiber filters. When the cleaning equipment is performing cleaning operations, the dust outlet cover 120 closes the dust outlet 112, and the exhaust port 115 draws air in, sucking garbage, dust, and other dirt into the dust collection chamber 111 through the dust inlet 114. The filter element 116 traps debris, dust, and other dirt in the dust collection chamber 111, while clean air filtered by the filter element 116 is discharged through the exhaust port 115, thus achieving dust collection. When the dust collection chamber 111 needs cleaning, the exhaust port 115 stops drawing air, the dust outlet cover 120 opens the dust outlet 112, and the dust-collecting airflow draws out the debris, dust, and other dirt from the dust collection chamber 111 through the dust outlet 112, thus achieving dust collection in the dust collection chamber 111.

[0073] This embodiment provides a protrusion 121 on the dust discharge port cover 120. When the dust discharge port 112 is closed, the protrusion 121 can extend into the dust collection chamber 111, causing a disturbance and dispersing effect on the accumulation of garbage near the dust discharge port 112. Thus, when the dust discharge port 112 is opened, the garbage originally accumulated at the dust discharge port 112 becomes loose due to the removal of the protrusion 121, making it easier for the dust collection airflow to carry it out smoothly from the dust discharge port 112, thereby improving the dust collection efficiency and effect of the dust collection box 110. Meanwhile, since the protrusion 121 extends into the dust collection chamber 111, during the operation of the dust collection box 110, the protrusion 121 will also interfere with the movement trajectory and accumulation position of large pieces of garbage near the dust discharge port 112, change their accumulation angle, and prevent them from being tightly accumulated near the dust discharge port 112, so as to form a relatively loose accumulation state, reduce the probability of large pieces of garbage clogging the dust discharge port 112, thereby further improving the dust collection effect and dust collection efficiency of the dust collection box 110.

[0074] It should be noted that during one dust collection cycle of the dust collection box 110 (i.e., from the start of dust collection to the completion of dust collection), the dust discharge port cover 120 can open and close the dust discharge port 112 only once, or it can open and close the dust discharge port 112 multiple times. Each time the dust discharge port cover 120 closes the dust discharge port 112, the protrusion 121 performs a corresponding insertion action into the dust discharge port 112. During this insertion, the protrusion 121 can push at least a portion of the debris (such as sunflower seed shells, paper scraps, etc.) that was stuck at the dust discharge port 112 after the previous dust collection operation back into the dust collection chamber 111, thus removing the debris from the position of the dust discharge port 112. In this way, when the dust discharge port 112 is opened again for dust collection, the garbage that has fallen back into the dust collection chamber 111 can be discharged from the dust discharge port 112 more smoothly, reducing the probability of getting stuck at the dust discharge port 112, and thus further reducing the probability of the dust discharge port 112 becoming blocked.

[0075] Optionally, please refer to Figure 7 and Figure 8 In one embodiment of this utility model, the protrusion 121 includes a cone 123, and the side of the dust discharge port cover 120 facing the dust discharge port 112 includes a shielding surface 122. The shape and size of the shielding surface 122 are adapted to the dust discharge port 112 so that the dust discharge port cover 120 can completely shield the dust discharge port 112 when in the closed position. The cone 123 includes a cone bottom surface 1233 and a cone top surface 1234. The cone bottom surface 1233 is connected to the shielding surface 122, and the cone top surface 1234 faces the dust collection chamber 111. It should be noted that the cone top surface 1234 can be a plane, an inclined plane, a concave-convex surface, or other shapes. In addition, it can be understood that when the area of ​​the cone top surface 1234 is small enough, close to a point, the cone top surface 1234 can also be a vertex structure. Optionally, in this embodiment, the cone top surface 1234 is approximately a planar structure. A planar structure is easy to manufacture and process, which helps to reduce production costs. At the same time, the planar structure can distribute stress evenly, avoiding local pressure concentration caused by sharp corners or curved surfaces, which in turn helps to enhance the strength and stiffness of the cone 123.

[0076] In one embodiment, the cone 123 can be a regular geometric cone, such as a cone, a triangular pyramid, or a square pyramid. In other embodiments, the cone 123 can also be a composite structure, such as a stepped cone structure formed by combining multiple cone surfaces with different cone angles, a cone structure combining a polygonal pyramid and a cone, or a cone structure with a streamlined curved surface that is concave or convex. In actual design and production, the specific structure of the cone 123 needs to be determined based on various factors such as the shape and size of the dust outlet 112.

[0077] In this embodiment, by setting the protrusion 121 as a cone 123 structure, on the one hand, the sharp tip 1234 of the cone 123 can more significantly disturb the garbage accumulation process when it extends into the dust collection chamber 111. This disturbance makes the garbage accumulate more loosely at the dust discharge port 112, further reducing the risk of garbage clogging the dust discharge port 112 and improving dust collection efficiency. On the other hand, the shape of the cone 123 allows the garbage in the dust collection chamber 111 to slide along the surface of the cone 123 during the accumulation process, creating a more favorable state for discharge. The cone tip 1234 faces the dust collection chamber 111, allowing the garbage to slide smoothly into the dust discharge port 112 when the dust discharge port cover 120 is opened. This design not only reduces the accumulation of garbage at the dust discharge port 112 but also optimizes the garbage discharge path, making it easier for garbage to be discharged from the dust collection chamber 111, thereby further improving the dust collection effect.

[0078] To facilitate the manufacturing and processing of the cone 123, optionally, in one embodiment of this utility model, please refer to... Figure 10 The cone 123 can be symmetrically arranged along the height direction of the shielding surface 122, such as... Figure 10 As shown in the Y2 axis direction. In another embodiment, please refer to... Figure 8 and Figure 12 The cone 123 can also be symmetrically arranged along the width direction of the blocking surface 122, such as... Figure 12 As shown in the X2 axis direction. In other embodiments, the cone 123 can also be symmetrically arranged both along the height direction and the width direction of the shielding surface 122. By symmetrically arranging the cone 123 along the height direction and / or the width direction of the shielding surface 122, this arrangement facilitates the design and processing of the dust outlet cover 120 forming mold, which helps to reduce manufacturing costs. At the same time, the symmetrical layout can also make the material more evenly stressed during stamping, injection molding and other molding processes, reduce deformation caused by uneven stress, and improve the consistency of finished product dimensions.

[0079] Optionally, in one embodiment of this utility model, please refer to Figure 8The cone 123 includes a first cone portion 1231 and a second cone portion 1232, which are connected to each other, and a top surface 1234 is formed at the connection position. The first cone portion 1231 and the second cone portion 1232 can be symmetrical or asymmetrical. There are various ways to connect the first cone portion 1231 and the second cone portion 1232. In one embodiment, the first cone portion 1231 and the second cone portion 1232 can be separately formed and then fixedly connected by bonding, riveting, or snap-fitting. In another embodiment, the first cone portion 1231 and the second cone portion 1232 can also be integrally formed by stamping, injection molding, or 3D printing. Optionally, in this embodiment, the first cone portion 1231 and the second cone portion 1232 are integrally injection molded and connected.

[0080] By designing the cone 123 as a combination structure including a first cone 1231 and a second cone 1232, the shape, size, or angle of the first cone 1231 and / or the second cone 1232 can be flexibly adjusted according to different needs, thereby achieving diversified designs for the cone 123 shape. This combination design not only improves the flexibility of the cone 123 shape design but also provides a more effective disturbance effect for different types of waste and accumulation states, thereby further optimizing the accumulation state of waste in the dust collection chamber 111, reducing the risk of blockage of the dust discharge port 112 during the dust collection process, and thus further improving dust collection efficiency.

[0081] Optionally, in one embodiment of this utility model, please refer to Figure 8 and Figure 17The first cone portion 1231 and the second cone portion 1232 are symmetrically arranged along the width direction of the shielding surface 122. This facilitates the positioning and processing of the first cone portion 1231 and the second cone portion 1232 on the dust outlet cover plate 120. The first cone portion 1231 includes a first inclined surface 12311 and a first conical surface 12312 connected to each other, and the second cone portion 1232 includes a second inclined surface 12321 and a second conical surface 12322 connected to each other. The first inclined surface 12311 and the second inclined surface 12321 are connected by abutting, and the first conical surface 12312 and the second conical surface 12322 are connected by abutting. It should be noted that there are multiple ways in which the first inclined surface 12311 and the second inclined surface 12321 are connected by abutting. For example, the first inclined surface 12311 and the second inclined surface 12321 can be directly connected by abutting, or they can be indirectly connected by abutting through other surfaces, such as curved surfaces, planes, or inclined surfaces. Similarly, there are various ways in which the first conical surface 12312 and the second conical surface 12322 can be connected. For example, the first conical surface 12312 and the second conical surface 12322 can be directly connected, or they can be indirectly connected through other surfaces, such as curved surfaces, planes, or inclined surfaces. Optionally, in this embodiment, the first conical surface 12312 and the second conical surface 12322 are directly connected. This allows for a relatively smooth connection between the first conical surface 12312 and the second conical surface 12322.

[0082] In one embodiment, please refer to Figure 8 and Figure 17 Along the height direction of the shielding surface 122, a first inclined surface 12311 is disposed above the first conical surface 12312, and a second inclined surface 12321 is also disposed above the second conical surface 12322. In another embodiment, along the height direction of the shielding surface 122, the first inclined surface 12311 is disposed below the first conical surface 12312, and the second inclined surface 12321 is also disposed below the second conical surface 12322.

[0083] In this embodiment, when the first cone portion 1231 and the second cone portion 1232 are connected, on the one hand, since the first inclined surface 12311 can be connected to the second inclined surface 12321, a continuous inclined transition structure can be formed at one end of the cone 123. This structure can generate a relatively uniform disturbance effect during the garbage accumulation process, making the garbage easier to slide under the action of the inclined surface, thereby further reducing the accumulation density of garbage near the dust discharge port 112. On the other hand, since the first cone portion 12312 and the second cone portion 12322 are connected, a smooth and continuous cone structure can be formed at the other end of the cone 123. This cone structure can further improve the accumulation state of garbage, keeping the garbage in a loose accumulation state under the action of the cone surface, thereby further reducing the risk of blockage of the dust discharge port 112.

[0084] Optionally, please refer to Figure 3 and Figure 8 In one embodiment of this utility model, the dust collection chamber 111 includes a bottom wall 1111. At the position where the dust discharge port cover 120 closes the dust discharge port 112, along the height direction of the dust collection chamber 111, as shown... Figure 3 As shown along the Z-axis, the first conical surface 12312 and the second conical surface 12322 are located on the side closer to the bottom wall 1111, while the first inclined surface 12311 and the second inclined surface 12321 are located on the side farther from the bottom wall 1111. This arrangement allows the cone 123 to form an approximately teardrop-shaped structure. After entering the dust collection chamber 111, the waste is first guided by the first inclined surface 12311 and the second inclined surface 12321, making it easier for it to slide towards the bottom wall 1111. Subsequently, the first conical surface 12312 and the second conical surface 12322 further agitate the waste near the bottom wall 1111, making the waste accumulation near the bottom wall 1111 more loose, thereby further reducing the probability of blockage in the dust discharge port 112 during dust collection. Furthermore, when waste accumulates in the dust collection chamber 111, larger pieces of waste typically accumulate near the bottom wall 1111. This results in a relatively greater impact force on the cone 123 from the side closest to the bottom wall 1111. Therefore, by positioning the first conical surface 12312 and the second conical surface 12322 on the side closest to the bottom wall 1111, the supporting strength and rigidity of the cone 123 near the bottom wall 1111 can be more effectively improved, thereby reducing the probability of damage to the cone 123 due to the greater impact force on that side.

[0085] Optionally, please refer to Figure 8 and Figure 17 In one embodiment of this utility model, a support ridge 12313 is formed on the first inclined surface 12311 and the second inclined surface 12321 at the docking connection position. The first inclined surface 12311 and the second inclined surface 12321 are docked together by the support ridge 12313, which is inclined relative to the shielding surface 122. In another embodiment, the first inclined surface 12311 and the second inclined surface 12321 form one inclined support ridge 12313 at the docking connection position. In another embodiment, the first inclined surface 12311 and the second inclined surface 12321 form multiple inclined support ridges 12313 at the docking position to form a multi-level support structure.

[0086] Optionally, in this embodiment, please participate Figure 8 and Figure 17An inclined support ridge 12313 is formed at the mating connection position of the first inclined surface 12311 and the second inclined surface 12321. Along the width direction of the shielding surface 122, one side of the support ridge 12313 is connected to the side of the first inclined surface 12311 away from the first conical surface 12312, and the other side of the support ridge 12313 is connected to the side of the second inclined surface 12321 away from the second conical surface 12322. It should be noted that the shape of the support ridge 12313 can be various, such as a plane, an inclined surface, or an arc surface. Optionally, in this embodiment, the support ridge 12313 is an approximately arc-shaped surface structure. Specifically, along the inclined direction of the support ridge 12313, one end of the support ridge 12313 in the length direction is connected to the top surface 1234 of the cone, and the other end of the support ridge 12313 in the length direction extends toward one side of the shielding surface 122 and is connected to the shielding surface 122. Along the inclination direction of the support edge 12313, the cross-section of the support edge 12313 gradually increases from the end near the top surface 1234 of the cone to the end near the shielding surface 122, forming an approximately arc-shaped fan-shaped surface structure. This arrangement can better improve the stress concentration generated at the joint position of the first inclined surface 12311 and the second inclined surface 12321.

[0087] In the above embodiment, by providing a support ridge 12313 between the first inclined surface 12311 and the second inclined surface 12321, the stress concentration at the joint of the first inclined surface 12311 and the second inclined surface 12321 can be improved, thereby increasing the overall support strength of the cone 123. Moreover, the design of the support ridge 12313 can improve the strength of the cone 123 while optimizing the manufacturing process of the cone 123, which is conducive to reducing the manufacturing cost of the cone 123.

[0088] Optionally, please refer to Figure 7 , Figure 8 and Figure 17 In one embodiment of this utility model, the first cone portion 1231 and the second cone portion 1232 are symmetrically arranged along the width direction of the shielding surface 122, and the first inclined surface 12311 and the second inclined surface 12321 are located on the side away from the bottom wall 1111, while the first cone portion 12312 and the second cone portion 12322 are located on the side close to the bottom wall 1111. A line 1221 is formed between the supporting edge 12313 and the shielding surface 122, and a point 1222 is formed between the connecting line of the first cone portion 12312 and the second cone portion 12322 and the shielding surface 122. Along the height direction of the shielding surface 122, the top surface 1234 of the cone is located between the line 1221 and the point 1222, and the minimum distance between the edge of the top surface 1234 and the line 1221 is greater than the maximum distance between the edge of the top surface 1234 and the point 1222. The minimum distance between the edge of the cone's top surface 1234 and the intersection line 1221 is Figure 17In the middle dimension A, the maximum distance between the edge of the top surface 1234 of the cone and the intersection point 1222 is Figure 17 Dimension B in the middle.

[0089] In the above embodiment, by positioning the top surface 1234 of the cone between the intersection line 1221 and the intersection point 1222, and ensuring that the minimum distance between its edge and the intersection line 1221 is greater than the maximum distance between its edge and the intersection point 1222, the top surface 1234 of the cone is positioned eccentrically close to the bottom wall 1111. With this configuration, after waste enters the dust collection chamber 111, it is first guided by the first inclined surface 12311 and the second inclined surface 12321, making it easier to slide towards the bottom wall 1111. Simultaneously, since the waste accumulation is denser in the area near the bottom wall 1111 of the dust collection chamber 111, the eccentric design of the top surface 1234 of the cone allows it to penetrate deeper into this area, achieving a greater insertion depth. This more effectively disturbs the waste accumulation in the area near the bottom wall 1111, making the waste accumulation looser and further reducing the risk of blockage at the dust outlet 112.

[0090] Optionally, in one embodiment of this utility model, please refer to Figures 14 to 16 The protrusion 121 includes at least one bent structure 124, one end of which is connected to the shielding surface 122, and the other end extends bent toward the dust collection chamber 111. The protrusion 121 may include one or more bent structures 124, which may be interconnected or independently arranged. The bent structure 124 can be formed in various ways, such as by bending a thin sheet or by injection molding. The bent structure 124 can be located in the central region of the shielding surface 122 or at any desired location, such as the edge region of the shielding surface 122. For example, in this embodiment, the protrusion 121 includes one bent structure 124, which is located near the center of the shielding surface 122. Specifically, the width direction of the bent structure 124 is consistent with the width direction of the shielding surface 122, and the length direction of the bent structure 124 is consistent with the height direction of the shielding surface 122. This design facilitates the molding and manufacturing of the bending structure 124 on the shielding surface 122.

[0091] By providing a bending structure 124 on the shielding surface 122, when the dust discharge port cover 120 is in the closed position of the dust discharge port 112, the bending structure 124 can disperse and disturb the accumulation process of the garbage near the dust discharge port 112 after the garbage enters the dust collection chamber 111. Through this disturbance, the garbage accumulates more loosely at the dust discharge port 112, thereby reducing the risk of garbage clogging the dust discharge port 112 and improving the dust collection efficiency. On the other hand, the garbage in the dust collection chamber 111 can slide along the surface of the bending structure 124 during the accumulation process, forming a state that is more conducive to discharge, thereby optimizing the discharge path of the garbage and making it easier for the garbage to be discharged from the dust collection chamber 111, further improving the dust collection effect.

[0092] Optionally, in one embodiment of this utility model, please refer to Figure 14 and Figure 16 The bending structure 124 includes a first bending segment 1241 and a second bending segment 1242. One end of the first bending segment 1241 is connected to the shielding surface 122, and the other end is connected to one end of the second bending segment 1242. The other end of the second bending segment 1242 is also connected to the shielding surface 122. The first bending segment 1241 and the second bending segment 1242 can be symmetrical or asymmetrical, and this embodiment is not limited to either. Various bending shapes, such as U-shaped bends and V-shaped bends, can be formed between the first bending segment 1241 and the second bending segment 1242. For example, in this embodiment, an approximately V-shaped bending structure 124 is formed between the first bending segment 1241 and the second bending segment 1242. This configuration simplifies the manufacturing process of the bending structure 124 and helps reduce its manufacturing cost.

[0093] In the above embodiment, by providing a first bending segment 1241 and a second bending segment 1242, the first bending segment 1241 and the second bending segment 1242 can be combined to form two bending surfaces. With this configuration, after the waste enters the dust collection chamber 111, the synergistic effect of the first bending segment 1241 and the second bending segment 1242 makes the accumulation of waste in the dust collection chamber 111 more loose, facilitating smooth discharge during subsequent dust collection processes, thereby reducing the risk of blockage at the dust discharge port 112.

[0094] Optionally, please refer to Figure 16 In one embodiment of this utility model, along the height direction of the shielding surface 122, the first bent segment 1241 is disposed above the second bent segment 1242, and the angle between the first bent segment 1241 and the shielding surface 122 is smaller than the angle between the second bent segment 1242 and the shielding surface 122. For example... Figure 16As shown, the angle between the first bending segment 1241 and the shielding surface 122 is α, and the angle between the second bending segment 1242 and the shielding surface 122 is β, where α < β. By making the angle between the first bending segment 1241 and the shielding surface 122 smaller than the angle between the second bending segment 1242 and the shielding surface 122, this arrangement achieves an asymmetrical arrangement of the bending structure 124, and makes the connection position of the first bending segment 1241 and the second bending segment 1242 closer to the bottom wall 1111 of the dust collection chamber 111. Thus, after the waste enters the dust collection chamber 111, it will first be guided by the first bending segment 1241, making it easier to slide towards the bottom wall 1111. Subsequently, the second bending segment 1242 further agitates the waste near the bottom wall 1111, making the waste accumulate more loosely near the bottom wall 1111. This makes it easier for the waste to be smoothly extracted from the dust discharge port 112 during dust collection, thereby further reducing the risk of blockage in the dust discharge port 112.

[0095] Optionally, in one embodiment of this utility model, please refer to Figures 18 to 21 The dust outlet cover 120 includes a shielding surface 122 on the side facing the dust collection chamber 111. The protrusion 121 includes a plate-shaped body 125, one end of which is connected to the shielding surface 122, and the other end extends into the dust collection chamber 111. The plate-shaped body 125 can be integrally formed and connected to the shielding surface 122, or it can be fixedly connected to the shielding surface 122 by means of bonding, snap-fitting, or hot-melt. The plate-shaped body 125 and the shielding surface 122 can be arranged perpendicularly or inclinedly, which is not limited in this embodiment. The shape of the plate-shaped body 125 can be any plate structure such as rectangular, semi-circular, triangular, or trapezoidal. It should be noted that, in this embodiment, the plate-shaped body 125 refers to a plate structure in the thickness direction of the plate-shaped body 125 where both surfaces are straight. The number of plate-shaped bodies 125 can be one, two, or more. For example, in this embodiment, the plate-shaped body 125 is a rectangular structure, and the number of plate-shaped bodies 125 is one.

[0096] By providing a plate-shaped body 125 on the shielding surface 122, and making the plate-shaped body 125 protrude towards the dust discharge port 112, the plate-shaped body 125 can form a protruding disturbance part within the dust collection chamber 111. This disturbance part can effectively agitate the waste within the dust collection chamber 111, making the waste accumulation near the dust discharge port 112 more loose, so that it can smoothly slide out from the dust discharge port 112 during the dust collection process, thereby reducing the risk of blockage of the dust discharge port 112. At the same time, since the shape and structure of the plate-shaped body 125 are relatively simple, it is easy to form and manufacture, which helps to reduce the manufacturing cost of the protrusion 121.

[0097] Optionally, in one embodiment of this utility model, please refer to Figures 18 to 21The plate-shaped body 125 is perpendicular to the shielding surface 122. This perpendicularity facilitates the molding and fabrication of the plate-shaped body 125 on the shielding surface 122, reducing manufacturing costs. Simultaneously, it allows the plate-shaped body 125 to more evenly agitate the accumulated waste near the dust outlet 112, preventing deformation or bending of the plate-shaped body 125 due to uneven stress on both sides, thus extending its service life.

[0098] Optionally, in one embodiment of this utility model, please refer to Figure 18 and Figure 19 The plate-shaped body 125 is arranged parallel to the width direction of the shielding surface 122. The length of the plate-shaped body 125 can be equal to or smaller than the width of the shielding surface 122. Optionally, in this embodiment, the length of the plate-shaped body 125 is approximately equal to the width of the shielding surface 122. This arrangement allows the plate-shaped body 125 to significantly disturb the accumulation of waste near the dust discharge port 112 in the width direction of the shielding surface 122. In another embodiment, please refer to... Figure 20 and Figure 21 The plate-shaped body 125 is arranged parallel to the height direction of the shielding surface 122. The length of the plate-shaped body 125 can be equal to or smaller than the length of the shielding surface 122. Optionally, in one embodiment, the length of the plate-shaped body 125 is approximately equal to the length of the shielding surface 122. This arrangement allows the plate-shaped body 125 to have a greater disturbance effect on the garbage accumulation process near the dust discharge port in the height direction of the shielding surface 122.

[0099] By arranging the plate-shaped body 125 parallel to the width direction or the height direction of the shielding surface 122, the molding process of the plate-shaped body 125 on the shielding surface 122 can be further simplified, which helps to further reduce manufacturing costs. At the same time, this arrangement allows the plate-shaped body 125 to better disperse impact force when subjected to garbage impact, reducing structural damage to the plate-shaped body 125 caused by garbage accumulation and extending its service life.

[0100] Please see Figure 24 and Figure 25 In one embodiment, two plate-shaped bodies 125 are provided, respectively labeled as first plate-shaped body 1251 and second plate-shaped body 1252, wherein the first plate-shaped body 1251 is arranged parallel to the width direction of the shielding surface 122, and the second plate-shaped body 1252 is arranged parallel to the height direction of the shielding surface 122.

[0101] It is understood that in some other embodiments, multiple plate-shaped bodies 125 may be provided, wherein some plate-shaped bodies 125 are arranged parallel to the width direction of the shielding surface 122, and other plate-shaped bodies 125 are arranged parallel to the height direction of the shielding surface 122.

[0102] Of course, in some other embodiments, multiple plate-shaped bodies 125 are provided, and the multiple plate-shaped bodies can also be provided at any angle inclined to the width direction or length direction of the shielding surface 122.

[0103] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
