Abstract
Description
Technical Field
[0001] This disclosure relates to a cleaning head for a surface cleaning device and a surface cleaning device. Background Technology
[0002] As residents' living standards improve, vacuum cleaners are entering more and more homes and gradually becoming a daily cleaning tool.
[0003] However, the floor brush on traditional vacuum cleaners is not very effective at cleaning the side areas, which means that some areas cannot be cleaned when the vacuum cleaner is working close to the edge, seriously affecting the user experience.
[0004] To address this technical problem, some existing vacuum cleaners have a side cleaning function. However, this function is mainly achieved by setting outward-protruding bristles inside the roller brush, or by installing a small side brush for lateral cleaning on the motor end via a bevel gear.
[0005] For designs with outward-protruding bristles inside the roller brush, the bristles interfere with the housing, resulting in a shorter lifespan. For designs using a small side brush for lateral cleaning mounted on the motor end via a bevel gear, the added bevel gear and other structures complicate the cleaning head's structure, consequently leading to a shorter overall lifespan.

[0043] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.
[0044] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0045] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.
[0046] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.
[0047] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.
[0048] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.
[0049] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values that would be recognized by one of ordinary skill in the art.
[0050] Figure 1 This is a schematic diagram of the structure of the cleaning head of a surface cleaning device according to one embodiment of the present disclosure. Figure 2 This is a structural schematic diagram of the cleaning head of a surface cleaning device according to one embodiment of the present disclosure from another angle.
[0051] like Figure 1 and Figure 2 As shown, the cleaning head of the surface cleaning device of this disclosure may include a housing 100, a cleaning brush 200, and a stirring element 300.
[0052] When the surface cleaning device of this disclosure is in use, it can be pushed by the user and moved forward. Therefore, the direction of the cleaning head of the surface cleaning device can be defined according to the direction of its movement; that is, the forward direction of the surface cleaning device is the forward direction of the cleaning head, and the direction opposite to this forward direction is the backward direction of the cleaning head. Correspondingly, the direction perpendicular to the forward-backward direction is the left-right direction of the cleaning head.
[0053] like Figure 1 and Figure 2 As shown, the housing 100 includes a first accommodating space and a second accommodating space, the first accommodating space being used to accommodate at least the stirring component 300, and the second accommodating space being used to accommodate at least the cleaning brush 200.
[0054] Specifically, the housing 100 of this disclosure includes two sidewalls in the left-right direction, wherein one sidewall 110 is formed as a space between a first receiving space and a second receiving space, that is, the first receiving space and the second receiving space are separated by the sidewall 110, that is, one surface of the sidewall 110 is used to define the first receiving space and the other surface of the sidewall 110 is used to define the second receiving space.
[0055] In a preferred embodiment, the second receiving space may be formed as a recessed portion of the housing 100, that is, the second receiving space of this disclosure is located entirely within the outline of the housing 100.
[0056] The housing 100 of this disclosure may also include a suction port, which may be located behind the first receiving space, and accordingly, dust disturbed by the agitator 300 can be sucked out through the suction port.
[0057] Although this disclosure Figure 1 and Figure 2 The cleaning head of the surface cleaning device shown is for use in dry surface cleaning devices. However, those skilled in the art should know that the cleaning brush 200 and other structures disclosed herein can also be used in wet surface cleaning devices. In this case, wastewater after use can be sucked up through the suction port.
[0058] In this disclosure, a cleaning brush 200 is rotatably mounted on a housing 100 and has at least one flexible bristle 220 extending radially outward from its axis of rotation, the at least one flexible bristle 220 being configured to rotate and engage with the surface to be cleaned; an agitator 300 is rotatably mounted within the housing 100; the cleaning brush 200 and the agitator 300 are arranged to rotate about a common axis of rotation, and at least a portion of the cleaning brush 200 is located outside a sidewall 110 on one side of the housing 100.
[0059] The structure of the cleaning brush and agitator of the surface cleaning apparatus of this disclosure will be described in detail below with reference to the accompanying drawings.
[0060] Figure 3 This is a partial structural diagram of the cleaning head of a surface cleaning device according to one embodiment of the present disclosure. Figure 4 This is a schematic diagram of the mounting connector 310 of the cleaning head of a surface cleaning device according to one embodiment of the present disclosure.
[0061] like Figure 3 and Figure 4 As shown, the stirring member 300 of this disclosure includes a first end and a second end opposite to the first end, wherein the first end and the second end are rotatably disposed on two side walls of the housing 100. The first end of the stirring member 300 is disposed close to the second receiving space.
[0062] like Figure 3 As shown, at least a portion of the first end of the agitator 300 passes through the side wall 110 of the housing 100 and is located outside the side wall 110. In a specific embodiment, the first end of the agitator 300 may include a rotating shaft portion 320 and a mounting connector 310. The rotating shaft portion 320 is rotatably disposed on the side wall 110 of the housing 100, and the mounting connector 310 can be fixed to the rotating shaft portion 320 and is located within a second receiving space, thereby enabling the mounting connector 310 to rotate synchronously with the agitator 300. Of course, the mounting connector 310 of this disclosure may also be integrally formed with the rotating shaft portion 320.
[0063] like Figure 4 As shown, the mounting connector 310 of this disclosure may include a base portion 311, a second axial limiting portion 312, and a second circumferential limiting portion 313.
[0064] The base portion 311 is formed as a cylindrical structure with a predetermined diameter. The second axial limiting portion 312 is formed as a protrusion that extends radially from the surface of the base portion 311 by a predetermined height, and the second axial limiting portion 312 extends circumferentially along the base portion 311 by a predetermined length, thereby forming the second axial limiting portion 312 as a protruding structure.
[0065] In a preferred embodiment, the second axial limiting portion 312 can be provided in multiple ways, for example, three. These three second axial limiting portions 312 can be distributed at equal intervals along the circumferential direction of the base portion 311.
[0066] The second circumferential limiting portion 313 of this disclosure is formed on one surface of the second axial limiting portion 312, and the second circumferential limiting portion 313 is disposed near the side wall 110 of the housing 100. Preferably, the second circumferential limiting portion 313 extends from one surface of the second axial limiting portion 312 along the axial direction of the base portion 311. Thus, the second axial limiting portion 312 and the second circumferential limiting portion 313 of this disclosure are integrally formed as the second joint portion of this disclosure, and the second joint portion is formed as a joint protrusion.
[0067] Figure 6 This is a schematic diagram of the structure of a cleaning brush of a surface cleaning device according to one embodiment of the present disclosure.
[0068] In this disclosure, the cleaning brush 200 is mounted to the first end outside the side wall 110 of the housing 100. That is, the cleaning brush 200 of this disclosure is located outside the side wall 110, and correspondingly, most of the agitator 300 is located inside the side wall 110.
[0069] In a preferred embodiment, the cleaning brush 200 is generally located within or flush with the outline of the housing 100. That is, when the cleaning head of the surface cleaning device of this disclosure is projected onto the surface to be cleaned, the cleaning brush 200 is not located outside the projection of the housing 100, thereby the cleaning brush 200 can be protected by the housing 100 and the service life of the cleaning brush 200 is improved.
[0070] Structurally, the cleaning brush 200 of this disclosure may include a hub 210 and flexible bristles 220; wherein the outer peripheral surface of the hub 210 is formed as a cylindrical surface, one end of the flexible bristles 220 is fixed to the outer peripheral surface of the hub 210, and the flexible bristles 220 are arranged radially along the hub 210.
[0071] Those skilled in the art will understand that the flexible bristles 220 of this disclosure can be configured in multiple ways, and these flexible bristles 220 can be arranged at equal or unequal intervals along the outer peripheral surface of the hub 210.
[0072] Based on the above structure, in this disclosure, the cleaning brush 200 can be installed onto the mixing element 300 by mounting the hub 210 onto the mounting joint 310; conversely, the cleaning brush 200 can be removed from the mixing element 300 by removing the hub 210 from the mounting joint 310. That is, the hub 210 of this disclosure is removably mounted onto the first end of the mixing element 300.
[0073] like Figure 6As shown, the hub 210 of this disclosure has a recessed groove, the diameter of which is the same as the diameter of the base portion 311, or the diameter of the recessed groove is slightly larger than the diameter of the base portion 311. Thus, at least a portion of the mounting joint 310 of this disclosure can be inserted into the recessed groove of the hub 210, thereby limiting the radial position of the hub 210 by the mounting joint 310.
[0074] Furthermore, the mounting joint 310 of this disclosure includes a connecting end and a free end, wherein the connecting end of the mounting joint 310 is one end of the rotating shaft portion 320 connected to the mounting joint 310. When the mounting joint 310 is connected to the hub 210, the end face of the free end of the mounting joint 310 can contact the bottom wall surface of the groove of the hub 210, thereby restricting the position of the mounting joint 310 and the hub 210 in one axial direction.
[0075] In this disclosure, the position of the mounting joint 310 and the hub 210 in another axial direction is achieved by the cooperation between the first joint and the second joint.
[0076] Specifically, the hub 210 includes a first axial limiting portion 211, which is formed by protruding inward from the side wall of the groove along the radial direction of the hub 210. The first axial limiting portion 211 extends a predetermined length along the circumferential direction of the hub 210.
[0077] One end of the first axial limiting portion 211 forms a limiting block 212, which extends from one surface of the first axial limiting portion 211 (the surface close to the bottom wall of the groove) along the axial direction of the hub 210. Thus, the first axial limiting portion 211 and the limiting block 212 can form a first joint portion of the hub, and when the cleaning brush 200 is connected to the agitator 300, the first joint portion and the second joint portion are complementaryly engaged.
[0078] Specifically, the first engagement portion includes an engagement groove, and the second engagement portion includes an engagement protrusion complementary to the engagement groove. When the cleaning brush 200 is attached to the agitator 300, the engagement protrusion is configured to be fixed (e.g., detachably fixed) within the engagement groove.
[0079] In a preferred embodiment, the engaging groove and engaging protrusion are configured to engage and fix each other in a first circumferential direction of the agitator 300, the first circumferential direction being the same as the rotation direction of the agitator 300, thereby preventing the cleaning brush 200 and the agitator 300 of this disclosure from disengaging from each other during rotation.
[0080] More preferably, a receiving groove 213 may be provided on one surface of the first axial limiting portion 211 (the surface near the bottom wall of the groove), which can accommodate the second circumferential limiting portion 313 described above. Thus, a more stable connection relationship can be formed between the cleaning brush 200 and the stirring member 300 of this disclosure.
[0081] Based on the above structure, when the cleaning head of the surface cleaning device disclosed herein is in use, the stirring element 300 is driven to rotate. At this time, one end of the second axial limiting part 312 of the mounting joint 310 will make pressure contact with the limiting block 212, and based on this pressure, the cleaning brush 200 is driven to rotate, thereby realizing the synchronous rotation of the cleaning brush 200 and the stirring element 300.
[0082] Furthermore, both the mating groove and the mating protrusion of this disclosure extend along a common axis.
[0083] In this disclosure, the rotating shaft portion 320 of the stirring component 300 can pass through the side wall 110 of the housing 100, and the cleaning brush 200 is removably mounted on the free end of the rotating shaft portion 320, that is, the mounting connector 310 can be fixed to the free end of the rotating shaft portion 320, and the cleaning brush 200 is removably mounted on the free end of the rotating shaft portion 320 through the mounting connector 310.
[0084] When in use, the cleaning head of the surface cleaning device disclosed herein rotates the agitator 300, which in turn drives the cleaning brush 200 to rotate, thus achieving the edge cleaning function of a vacuum cleaner. Therefore, the cleaning head of the surface cleaning device of this disclosure does not require an additional transmission mechanism, saving costs. Furthermore, the cleaning brush 200 of this disclosure can be easily disassembled, facilitating its maintenance.
[0085] According to another aspect of this disclosure, a surface cleaning device is provided, which includes the cleaning head of the surface cleaning device described above.
