Description

Technical Field

[0001] This application relates to the field of environmental cleaning electrical appliances, and in particular to a main unit of a cleaning device and a cleaning device. Background Technology

[0002] The dust cup of existing vacuum cleaners is usually made of plastic, with a swivel end at the bottom that mates with the bottom cover of the dust cup. The swivel end enables rotational sealing and facilitates one-button dust emptying. The upper part of the dust cup connects to the main body assembly, while the bottom cover of the main body serves as a support structure, allowing the vacuum cleaner to be placed stably on a horizontal surface.

[0003] However, when a vacuum cleaner is accidentally dropped, the shaft end is prone to breakage, which in turn affects the opening and closing and sealing of the dust cup. Utility Model Content

[0004] Based on this, this application provides a main unit and a cleaning device for a cleaning device to address the shortcomings of related technologies.

[0005] In a first aspect, this application provides a main unit for a cleaning device, comprising:

[0006] The dust cup assembly includes a cup body, a cup lid, and a rotating shaft. The cup lid is rotatably connected to the first end of the cup body via the rotating shaft.

[0007] The body assembly has a second end of the cup body connected to it. The body assembly has a support surface and a clearance groove. The support surface, clearance groove and cup lid are located at the same end of the cup body. At least part of the sidewall of the clearance groove protrudes from the support surface. The pivot is located in the clearance groove.

[0008] The main unit of the cleaning device in this embodiment of the application is provided with a cup body for collecting dirt, a cup lid for opening or closing the cup body, thereby facilitating the cleaning of dirt inside the cup body, and a rotating shaft for rotatably connecting the cup lid and the cup body, so that the cup lid can rotate relative to the cup body, thereby facilitating the opening or closing of the cup body. A support surface is provided to stably stand the main unit of the cleaning device, thereby facilitating the placement or storage of the main unit of the cleaning device. An obstacle groove is provided to provide rotation space for the rotating shaft. Since the rotating shaft is set in the obstacle groove and the side wall of the obstacle groove protrudes from the support surface, the side wall of the obstacle groove can provide good protection for the rotating shaft, thereby improving the structural strength and support stability of the rotating shaft under drop or external force, thereby preventing the rotating shaft from breaking.

[0009] In one possible implementation, the clearance groove includes a first sidewall and a second sidewall, which are arranged opposite to each other along the axial direction of the shaft.

[0010] Along the axis of rotation, the orthographic projection of the shaft lies within the orthographic projection of the first sidewall, and the orthographic projection of the shaft lies within the orthographic projection of the second sidewall.

[0011] In this way, both the first and second sidewalls protrude from the pivot, and the first and second sidewalls can better protect the pivot.

[0012] In one possible implementation, the first and second sidewalls are arranged symmetrically.

[0013] Thus, the symmetrical design simplifies the machining process of the clearance groove, and the first and second sidewalls can provide comprehensive protection for the shaft, thereby effectively preventing the shaft from breaking when subjected to external forces.

[0014] In one possible implementation, the first sidewall includes a first sub-sidewall and a second sub-sidewall connected to each other, the second sub-sidewall being disposed relative to the first sub-sidewall toward a first end of the cup body, and the first sub-sidewall protruding from the support surface.

[0015] Thus, since the first sub-sidewall protrudes from the support surface, it can form a protective barrier on the outside of the shaft. The first sub-sidewall can improve the support performance of the body components on the shaft, thereby effectively preventing the shaft from breaking due to impact when the main unit of the cleaning equipment is subjected to impact.

[0016] In one possible implementation, the first sub-sidewall is a flexible element.

[0017] This allows the first sub-sidewall to have elasticity, thereby improving the buffering performance of the first sub-sidewall and preventing it from cracking when subjected to impact.

[0018] In one possible implementation, the outer edge of the first sub-sidewall extends along an arc away from the second sub-sidewall.

[0019] In this way, stress concentration can be avoided on the first sub-sidewall when the main unit of the cleaning equipment falls, thereby increasing the strength of the first sub-sidewall and preventing damage to it.

[0020] In one possible implementation, the body assembly includes an interconnected main body and a lower cover, with the cup body connected to the main body and the clearance groove and support surface located on the lower cover.

[0021] In this way, dividing the fuselage assembly into the main body and the lower cover makes it easier to process the main body and the lower cover separately, and also makes it easier to process the clearance groove and support surface on the lower cover, and then install the lower cover onto the main body, thereby assembling a relatively complete fuselage assembly.

[0022] In one possible implementation, the cup body includes a cup body body and a first rotatable connection part connected to each other, and the cup lid includes a lid body and a second rotatable connection part connected to each other, with the first rotatable connection part being rotatably connected to the second rotatable connection part via a rotating shaft.

[0023] At least a portion of the first rotating connection is located within the clearance groove, and at least a portion of the second rotating connection is located within the clearance groove.

[0024] Thus, through the cooperation of the first rotating connecting part, the second rotating connecting part, and the rotating shaft, a rotating connection between the lid and the cup body can be achieved, thereby facilitating the opening and closing of the cup lid. Furthermore, since the first and second rotating connecting parts can be partially or entirely located within the clearance groove, the sidewalls of the clearance groove can also protect the first and second rotating connecting parts.

[0025] In one possible implementation, the cup lid also includes a reinforcing rib, which connects the lid body and the second rotating connection portion, and the reinforcing rib is located outside the clearance groove.

[0026] Thus, by setting reinforcing ribs on the cup lid and connecting the lid body and the second rotating connection part through the reinforcing ribs, the strength of the second rotating connection part can be improved. As a result, when the rotating shaft and the second rotating connection part are integrally formed, the reinforcing ribs can improve the strength of the rotating shaft, thereby effectively improving the impact resistance of the rotating shaft.

[0027] Secondly, this application provides a cleaning device, comprising:

[0028] The main unit of the cleaning equipment provided in the first aspect above;

[0029] A cleaning brush head, which is connected to the main unit of the cleaning device.

[0030] Cleaning brush head, which is connected to the main unit of the cleaning equipment.

[0044] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0045] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0046] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on 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.

[0047] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0048] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0049] The dust cup of existing vacuum cleaners is usually made of plastic, with a swivel end at the bottom that mates with the bottom cover of the dust cup. The swivel end enables rotational sealing and facilitates one-button dust emptying. The upper part of the dust cup connects to the main body assembly, while the bottom cover of the main body serves as a support structure, allowing the vacuum cleaner to be placed stably on a horizontal surface.

[0050] However, because the bottom surface of the lower cover is higher than the pivot end, the lower cover provides insufficient support for the pivot end. When the vacuum cleaner is accidentally dropped, the pivot end is prone to breakage. This not only affects the durability of the vacuum cleaner, but also causes the dust cup and bottom cover to fail to open and close, and affects the sealing performance between the dust cup and the bottom cover, resulting in dust leakage.

[0051] In view of the above problems, this application provides a main unit of a cleaning device and a cleaning device, wherein the rotating shaft is hidden in a relief groove to protect the rotating shaft, and part of the side wall of the relief groove protrudes from the support surface so that when the main unit of the cleaning device is accidentally dropped, the side wall of the relief groove can provide support and cushioning for the rotating shaft, thereby preventing the impact force from acting directly on the rotating shaft and thus preventing the rotating shaft from being damaged.

[0052] The following describes in detail, with reference to the accompanying drawings, the main unit of the cleaning equipment and the specific implementation of the cleaning equipment provided in this application.

[0053] Reference Figures 1 to 6 As shown, the main unit of the cleaning equipment provided in this application embodiment includes a dust cup assembly 100 and a body assembly 200. The dust cup assembly 100 includes a cup body 110, a cup lid 120 and a rotating shaft 130. The cup lid 120 is rotatably connected to the first end of the cup body 110 through the rotating shaft 130, and the second end of the cup body 110 is connected to the body assembly 200.

[0054] The body assembly 200 has a support surface 210 and a clearance groove 220. The support surface 210, the clearance groove 220 and the cup lid 120 are located at the same end of the cup body 110. At least a portion of the sidewall of the clearance groove 220 protrudes from the support surface 210, and the pivot 130 is located within the clearance groove 220.

[0055] The main unit of the cleaning device in this embodiment can collect dirt under the action of negative pressure suction, thereby completing the cleaning operation of the surface to be cleaned.

[0056] It should be noted that the main unit of the cleaning equipment may also include a fan and a battery. The fan and battery are installed in the body assembly 200. The battery can power the fan, thereby driving the fan to operate. The fan can provide negative pressure suction to the dust cup assembly 100, thereby sucking the dirt on the surface to be cleaned into the dust cup assembly 100.

[0057] The dust cup assembly 100 can be used to cyclone separate dust and airflow, thereby collecting the dust inside the dust cup assembly 100 and discharging the airflow from the dust cup assembly 100.

[0058] Specifically, the dust cup assembly 100 may include a cup body 110 and a cup lid 120 connected to each other, thereby defining a dust collection chamber together with the cup body 110 and the cup lid 120. Since the cup lid 120 is rotatably connected to the cup body 110 through a rotating shaft 130, the cup lid 120 can rotate about the axis of the rotating shaft 130 toward the cup body 110 so that the cup lid 120 closes the dust collection chamber. Alternatively, the cup lid 120 can rotate about the axis of the rotating shaft 130 away from the cup body 110 so that the cup lid 120 opens the dust collection chamber, thereby facilitating the cleaning of dirt in the dust collection chamber.

[0059] The rotating shaft 130 can be set independently, or the rotating shaft 130 can be integrally formed with one of the cup body 110 and the cup lid 120. This application embodiment does not limit this.

[0060] In this embodiment, part of the sidewall of the cup body 110 is fitted to the body assembly 200. The cup body 110 can be detachably connected to the body assembly 200 so that the dust cup assembly 100 can be completely removed from the body assembly 200, thereby facilitating deep cleaning of the dust cup assembly 100.

[0061] The dust cup assembly 100 is disassembled and assembled along the direction of... Figure 2 In the up-down direction, when the dust cup assembly 100 moves downward relative to the body assembly 200, the dust cup assembly 100 can be removed from the body assembly 200.

[0062] Understandably, if the rotating shaft 130 deforms or breaks, it will affect the rotation of the cup lid 120, causing the cup lid 120 to be unable to open or close smoothly, thus affecting the normal use of the dust cup assembly 100. In some cases, the cup lid 120 may even separate from the cup body 110, causing the dust cup assembly 100 to malfunction.

[0063] To solve this problem, the fuselage assembly 200 of this application embodiment is provided with a clearance groove 220, in which the rotating shaft 130 can be placed. A portion of the sidewall of the clearance groove 220 can protrude from the support surface 210, thereby making the sidewall of the clearance groove 220 protrude from the rotating shaft 130, and thus enabling the sidewall of the clearance groove 220 to protect the rotating shaft 130.

[0064] In this way, when the main unit of the cleaning equipment is accidentally dropped or subjected to external force, the impact or external force will act on the side wall of the relief groove 220 first, instead of directly acting on the rotating shaft 130. The side wall of the relief groove 220 can play a buffering role, disperse the force and enhance local support, thereby preventing the rotating shaft 130 from being damaged.

[0065] For example, when Figure 2 When the main unit of the illustrated cleaning equipment falls to the ground, because the lowest point of the side wall of the clearance groove 220 is lower than the pivot 130, the side wall of the clearance groove 220 contacts the ground, and the pivot 130 does not directly contact the ground. The side wall of the clearance groove 220 can better protect the pivot 130. The side wall of the clearance groove 220 can protect the pivot 130 in both the vertical and horizontal directions as well as the front and back directions.

[0066] The support surface 210 of the body assembly 200 is flat, so that the main unit of the cleaning equipment can be stably erected on a horizontal surface, making it convenient to place or store the main unit of the cleaning equipment. The bottom surface of the dust cup assembly 100 can be slightly lower than the support surface 210, so that the main unit of the cleaning equipment can cooperate with the cleaning base station to perform self-dust collection operation.

[0067] The main unit of the cleaning device in this embodiment includes a dust cup assembly 100 and a body assembly 200. The dust cup assembly 100 includes a cup body 110, a cup lid 120 and a rotating shaft 130. The body assembly 200 includes a support surface 210 and a clearance groove 220. The cup body 110 is designed to collect waste, and the cup lid 120 is designed to open or close the cup body 110, thus facilitating the cleaning of waste inside the cup body 110. The rotating shaft 130 is designed to rotatably connect the cup lid 120 and the cup body 110, allowing the cup lid 120 to rotate relative to the cup body 110, thereby facilitating the opening or closing of the cup body 110. The support surface 210 is designed to stably support the main unit of the cleaning equipment, thus facilitating the placement or storage of the main unit of the cleaning equipment. The clearance groove 220 is designed to provide rotation space for the rotating shaft 130. Since the rotating shaft 130 is located in the clearance groove 220 and the side wall of the clearance groove 220 protrudes from the support surface 210, the side wall of the clearance groove 220 can provide good protection for the rotating shaft 130, thereby improving the structural strength and support stability of the rotating shaft 130 under drop or external force, thus preventing the rotating shaft 130 from breaking.

[0068] Reference Figure 4 As shown, in one possible implementation, the clearance groove 220 includes a first sidewall 221 and a second sidewall 222, which are arranged opposite to each other along the axial direction of the rotating shaft 130. Along the axial direction of the rotating shaft 130, the orthographic projection of the rotating shaft 130 is located within the orthographic projection of the first sidewall 221, and the orthographic projection of the rotating shaft 130 is located within the orthographic projection of the second sidewall 222.

[0069] In other words, in the axial direction of the rotating shaft 130, the orthographic projection of the first sidewall 221 covers the orthographic projection of the rotating shaft 130, and the orthographic projection of the second sidewall 222 also covers the orthographic projection of the rotating shaft 130. When the main unit of the cleaning equipment follows... Figure 2 When the shaft is placed upright, the rotating shaft 130 is hidden in the clearance groove 220.

[0070] In this way, the lowest point of the first sidewall 221 and the lowest point of the second sidewall 222 are both lower than the rotating shaft 130, and the first sidewall 221 and the second sidewall 222 can better protect the rotating shaft 130.

[0071] In some embodiments, the first sidewall 221 and the second sidewall 222 are symmetrically arranged.

[0072] Thus, the symmetrical design simplifies the machining process of the clearance groove 220, and the first sidewall 221 and the second sidewall 222 can provide more comprehensive protection for the shaft 130 in the axial direction, thereby effectively preventing the shaft 130 from breaking when subjected to external forces.

[0073] Reference Figure 5 , Figure 7 and Figure 8 As shown, in some embodiments, the first sidewall 221 includes a first sub-sidewall 2211 and a second sub-sidewall 2212 connected to each other. The second sub-sidewall 2212 is disposed relative to the first sub-sidewall 2211 toward the first end of the cup body 110, and the first sub-sidewall 2211 protrudes from the support surface 210.

[0074] In this way, since the first sub-sidewall 2211 protrudes from the support surface 210, the first sub-sidewall 2211 can form protection on the outside of the rotating shaft 130. The first sub-sidewall 2211 can improve the support performance of the body assembly 200 on the rotating shaft 130, thereby effectively preventing the rotating shaft 130 from breaking due to impact force when the main unit of the cleaning equipment is impacted.

[0075] Similarly, the second sidewall 222 may include a third sub-sidewall and a fourth sub-sidewall that are connected to each other. The fourth sub-sidewall is disposed relative to the third sub-sidewall toward the first end of the cup body 110, and the third sub-sidewall protrudes from the support surface 210.

[0076] In some embodiments, the first sub-sidewall 2211 is a flexible element.

[0077] It is understandable that the first sub-sidewall 2211 and the second sub-sidewall 2212 can be processed separately, and then the first sub-sidewall 2211 and the second sub-sidewall 2212 can be connected. For example, the second sub-sidewall 2212 can be made of ABS (acrylonitrile-butadiene-styrene copolymer). ABS has high hardness. The first sub-sidewall 2211 can be made of materials such as silicone rubber or natural rubber to make the first sub-sidewall 2211 elastic, thereby improving the cushioning performance of the first sub-sidewall 2211 and preventing the first sub-sidewall 2211 from cracking when it is impacted.

[0078] Alternatively, the first sub-sidewall 2211 can be integrally formed with the second sub-sidewall 2212. That is, the second sub-sidewall 2212 can be processed first, and then the first sub-sidewall 2211 and the second sub-sidewall 2212 can be formed as a whole by injection molding.

[0079] Reference Figure 7As shown, in some embodiments, the outer edge of the first sub-sidewall 2211 extends along an arc away from the second sub-sidewall 2212.

[0080] If the outer edge of the first sub-sidewall 2211 facing away from the second sub-sidewall 2212 extends in a straight line, the outer edge of the first sub-sidewall 2211 forms a sharp angle, which is not conducive to improving the structural strength of the first sub-sidewall 2211. Therefore, the outer edge of the first sub-sidewall 2211 facing away from the second sub-sidewall 2212 extends in an arc, which can prevent stress concentration in the first sub-sidewall 2211 when the main unit of the cleaning equipment falls, thereby improving the strength of the first sub-sidewall 2211 and preventing damage to the first sub-sidewall 2211.

[0081] For example, the outer edge of the first sub-sidewall 2211 can be a semi-circular arc, or the outer edge of the first sub-sidewall 2211 can be wavy.

[0082] Reference Figure 3 , Figure 4 As shown, in one possible implementation, the body assembly 200 includes a body body 200a and a lower cover 200b connected to each other, the cup body 110 is connected to the body body 200a, and the clearance groove 220 and the support surface 210 are located on the lower cover 200b.

[0083] Thus, dividing the fuselage assembly 200 into the fuselage body 200a and the lower cover 200b is beneficial for processing the fuselage body 200a and the lower cover 200b separately, and for machining the clearance groove 220 and the support surface 210 on the lower cover 200b, and then installing the lower cover 200b onto the fuselage body 200a, thereby assembling a relatively complete fuselage assembly 200.

[0084] The main body 200a has a fan cavity and a battery cavity, with the fan installed in the fan cavity and the battery installed in the battery cavity.

[0085] Reference Figure 3 , Figure 8 As shown, in some embodiments, the cup body 110 includes a cup body 111 and a first rotatable connecting portion 112 connected to each other, and the cup lid 120 includes a lid body 121 and a second rotatable connecting portion 122 connected to each other. The first rotatable connecting portion 112 is rotatably connected to the second rotatable connecting portion 122 via a rotating shaft 130. At least a portion of the first rotatable connecting portion 112 is located within a clearance groove 220, and at least a portion of the second rotatable connecting portion 122 is located within a clearance groove 220.

[0086] In this way, through the cooperation of the first rotating connecting part 112, the second rotating connecting part 122, and the rotating shaft 130, the lid 121 and the cup body 111 can be rotatably connected, thereby facilitating the opening and closing of the cup lid 120 and the cup body 110. Furthermore, since the first rotating connecting part 112 and the second rotating connecting part 122 can be partially or entirely located within the relief groove 220, the sidewall of the relief groove 220 can also protect the first rotating connecting part 112 and the second rotating connecting part 122.

[0087] The rotating shaft 130 can be integrally formed with the first rotating connecting part 112, and the rotating shaft 130 can be connected with the second rotating connecting part 122, thereby realizing the rotatable connection between the cup lid 120 and the cup body 110. Alternatively, the rotating shaft 130 can be integrally formed with the second rotating connecting part 122, and the rotating shaft 130 can be connected with the first rotating connecting part 112, thereby realizing the rotatable connection between the cup lid 120 and the cup body 110.

[0088] Reference Figure 7 , Figure 8 As shown, in one possible implementation, the cup lid 120 further includes a reinforcing rib 123, which connects the lid body 121 and the second rotating connection portion 122, and the reinforcing rib 123 is located outside the relief groove 220.

[0089] Thus, by providing reinforcing ribs 123 on the cup lid 120 and connecting the lid body 121 and the second rotating connection part 122 through the reinforcing ribs 123, the strength of the second rotating connection part 122 can be improved. As a result, when the rotating shaft 130 and the second rotating connection part 122 are integrally formed, the reinforcing ribs 123 can improve the strength of the rotating shaft 130, thereby effectively improving the impact resistance of the rotating shaft 130.

[0090] In addition, this application embodiment also provides a cleaning device, which includes a cleaning brush head and a main unit of the cleaning device provided in the above embodiment, wherein the cleaning brush head is connected to the main unit of the cleaning device.

[0091] The structure and working principle of the main unit of the cleaning equipment have been described in detail in the foregoing embodiments, and will not be repeated here.

[0092] The main unit of the cleaning device can provide suction to the cleaning brush head and collect dirt. Since the cleaning brush head is detachably connected to the main unit of the cleaning device, the cleaning brush head can be selected according to the needs of the usage scenario.

[0093] For example, when cleaning the floor, the cleaning brush head can be a floor brush; or, when cleaning corners and crevices, the cleaning brush head can be a flat-nozzle brush. This application does not limit the specific structure of the cleaning brush head.

[0094] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
