[0027] The present disclosure will be described in further detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are merely exemplary and are not limiting to the present disclosure. In addition, it should also be understood that for the convenience and clarity of the description, only parts of the relevant are shown in the drawings.

[0028] It should be noted that the embodiments and features of the embodiments in the present disclosure can be combined with each other without conflict. The technical solutions of the present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.

[0029] Unless otherwise specified, the exemplary embodiments / examples shown will be understood as providing exemplary features of various details of some ways in which the technical concepts of the present disclosure can be implemented in practice. Therefore, unless otherwise specified, the features of various embodiments / examples can be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of the present disclosure.

[0030] In the drawings, cross-hatching and / or shading are generally used to make the boundaries of adjacent components clear. As such, unless specifically stated otherwise, the presence of cross-hatching or shading in a figure is not meant to imply that a particular material, material property, dimension, ratio, etc. is being represented in a specific manner. In addition, for clarity and / or descriptive purposes, the dimensions and / or relative dimensions of the components shown in the figures can have been exaggerated or can otherwise not be drawn to scale. When exemplary examples can be practiced differently, a specific process sequence can be performed in a different order than the described order or sequentially. For example, two sequentially described processes can be performed at substantially the same time or in the reverse order as described. Moreover, like reference numerals designate like components.

[0031] When a component is referred to as being "on" or "over" another component, "connected to" or "coupled to" another component, it can be directly on, directly connected to, or directly coupled to the other component, or intervening components can be present. However, when a component is referred to as being "directly on", "directly connected to", or "directly coupled to" another component, there are no intervening components present. For this reason, the term "connected" can refer to a physical connection, an electrical connection, etc., with or without intervening components.

[0032] For descriptive purposes, the disclosure can use spatially relative terms, such as "below," "lower," "under," "less than," "above," "upper" and "on" and the like, to describe the relative relationship between one component and another component as the figure(s) illustrated. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientations depicted in the figures. For example, if the device in the figures is turned over, then a component described as "below" or "under" another component or feature would then be oriented "above" the other component or feature. Thus, the exemplary term "below" can encompass both an orientation of above and below. Moreover, the device can be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0033] The terminology used herein is for the purpose of describing particular examples only and is not intended to be limiting. As used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. Furthermore, to the extent that the terms "including," "includes," "containing," "contains," or "containing," "contains," or variants thereof are used in either the detailed description or the claims, such terms are intended to be inclusive in a manner similar to the term "comprising" as an open term with the most

[0034] Among various surface cleaning heads, a cleaning head for soft surfaces is suitable for cleaning soft floor surfaces such as bed surfaces, sofa surfaces, and carpets. Such a cleaning head is typically designed to be compact in space to facilitate the user's flexible operation on the above-mentioned surfaces. However, such a cleaning head can face some problems in later maintenance. Due to the limitation of the design space, the roller brush cavity space is small, which is easy to accumulate dirt particles, and the roller brush is more likely to entangle hair or long lines due to the smaller diameter. Therefore, it is inconvenient to remove the roller brush from the cleaning head or clean the accumulated particle residues on the cleaning head.

[0035] Examples of the present disclosure provide a roller brush cavity in a cleaning head to be detachable from the cleaning head, so that the detached roller brush cavity is convenient for the user to clean by washing, and after the roller brush cavity is detached, the roller brush is exposed to a relatively open space, which is convenient for maintenance and cleaning thereof.

[0036] Figure 1A cleaning head 100 is shown. The cleaning head 100 is adapted to be attached to a suction nozzle of a surface cleaning apparatus for cleaning a surface to be cleaned. The cleaning head 100 has a main body portion 110 and a connecting portion 120 for attaching the cleaning head 100 to a surface cleaning apparatus, for example to a suction nozzle of a surface cleaning apparatus.

[0037] The main body portion 110 comprises a housing 111 and side faces 112, 113 which together form a roll brush cavity 116 within the cleaning head 100. A suction opening 114 is provided on the underside of the main body portion 110. A roll brush 130 is normally housed within the roll brush cavity 116.

[0038] As Figure 2 shown, the main body portion 110 comprises a support 115, the suction opening 114 being located at the bottom of the support 115 and in communication with the roll brush cavity 116. In one example, the support 115 is configured to be pivotally connected to the main body portion 110 about a longitudinal axis. In a preferred example, the support 115 is formed as an integral part of the main body portion 110 and is pivotally connected to the cleaning head 100 about the longitudinal axis L of the roll brush 130 together with the main body portion 110.

[0039] In use, the roll brush 130 acts to beat and agitate dirt and dust on the surface being cleaned. The roll brush 130 can be provided with nylon bristle strips and rows of bristles to help improve the pick-up performance of the cleaning head.

[0040] The roll brush cavity 116 can sometimes become clogged with dirty particles inside and elongate particles such as hair can become entangled around the roll brush 130. When this happens, it is necessary to be able to remove the roll brush cavity 116 from the cleaning head 100 and to dismount the roll brush 130 for thorough cleaning and then to re-mount it back in place in the cleaning head 100 once the cleaning has been completed.

[0041] As Figure 2 shown, the main body portion 110 is able to be mounted on and dismounted from the cleaning head 100 in relation to the cleaning head main body along the direction of the longitudinal axis L of the roll brush 130. The dismounting of the roll brush 130 is dependent on the dismounting of the main body portion 110. That is, when the main body portion 110 is dismounted, the roll brush 130 is exposed on the cleaning head 100, thereby providing a free end 130A which can be grasped by a user to facilitate the dismounting of the roll brush from the cleaning head 100.

[0042] As Figure 2 , Figure 4 and Figure 5As shown, the roller brush mounting end 130B is held within the roller brush cavity 116 on the cleaning head due to its proximity to the pivot point. A snap-fit ​​structure 200 can be provided to hold the mounting end 100B of the roller brush 130 on the cleaning head. The snap-fit ​​structure 200 can be, for example, in the form of a groove, which engages with a complementary engagement portion 201 on a support structure 118 provided on the side wall 100A of the cleaning head. The engagement portion 201 can be, for example, in the form of a spring.

[0043] Figure 5 The image shows the cleaning head 100 in a state where the roller brush 130 has been removed from the drive member 118A. In one example, at least a portion of the support structure 118 includes the drive member 118A, which is pivotally fixed to the inside of the sidewall 100A of the cleaning head 100 to provide self-rotational power for the roller brush. The drive member 118A internally houses the drive motor of the roller brush 130, and the power is transmitted to a power output end via a transmission mechanism. A drive claw 118B is disposed on the power output end. When the roller brush 130 is positioned on the drive member 118A, the drive claw 118B engages with a structure on the interior of the roller brush 130. In use, rotation of the drive motor causes the drive claw 118B to rotate, and the roller brush 130 subsequently rotates within the roller brush cavity 116 of the cleaning head 100.

[0044] like Figure 2 Combination Figure 6 As shown, during the process of removing the main body 110 from the cleaning head, the main body of the roller brush 130 is passed through the guide hole 112B on the side wall 112A of the main body 110. Then as... Figure 5 The removal of the roller brush 130 is performed by axially sliding the roller brush 130 away from the drive member 118A. The reinstallation of the roller brush 130 and the main body in the cleaning head 100 is performed by performing the above steps in reverse.

[0045] like Figure 4 and Figure 6 As shown, since the main body 110 needs to be fixed to the cleaning head, a fixing structure 300 is provided on one end of the cleaning head to fix the main body 110 to the cleaning head. The fixing structure 300 can be, for example, a guide groove structure, to engage with a complementary connecting portion 301 of the main body 110. The connecting portion 301 can be, for example, a guide rib structure that mates with the guide groove.

[0046] An end cap 110B may be provided at one end of the main body 110, and a connecting part is provided on the end cap 110B so that when the user twists the end cap 110B, the connecting part 301 is fastened or unfastened to the fixing structure 300, thereby fixing it to one end of the cleaning head, or removing the end cap 110B from one end of the cleaning head, so as to realize the fixing and removal of the main body 110 on the cleaning head.

[0047] In one example, the end cap 110B is pivotable relative to the support 115, such that when the end cap 110B is secured to the cleaning head, the cleaning head is able to pivot relative to the support 115. It is useful to enable the cleaning head to pivot relative to the support 115, such that the cleaning head can swing back and forth as the support 115 is engaged with the surface to be cleaned. Such swinging of the cleaning head as it is pushed and pulled across the surface to be cleaned does not interfere with the engagement of the support 115 with the surface to be cleaned, thereby allowing the suction openings 114 on the support 115 to remain in close proximity to the surface to be cleaned, reducing the loss of air pressure from the vacuum.

[0048] After the end cap 110B is unlocked from the cleaning head, the main body 110 is pulled out of the cleaning head along the longitudinal axis of the roller brush 130 to disassemble the cleaning head, and the first end of the main body 110 can not necessarily have a side wall. In particular, the guide hole 112B on the aforementioned first end of the main body 110 can have a diameter sufficient to allow the first end side wall of the cleaning head to cooperate with the rest of the main body to form the roller brush cavity 116 when the main body 110 is mounted on the cleaning head. Generally, the guide hole 112B should have a diameter greater than the cross-sectional profile of the roller brush to avoid interference during disassembly of the main body 110. However, it is also advantageous for the guide hole 112B to have a reduced diameter, particularly when it is substantially the same as or slightly smaller than the cross-sectional diameter of the roller brush 130. During disassembly of the main body, the guide hole 112B interferes with the bristles of the roller brush away from its longitudinal axis, and as the disassembly process progresses, the dirt particles adhering to the surface of the roller brush 130 are scraped off and collected into the roller brush cavity 116. That is, the guide hole 112B can play a role in preliminary removal of dirt from the surface of the roller brush 130.

[0049] The main body 110 can form the main part of the cleaning head alone, but in order to ensure the reliability of the overall structure, in one example, as shown in Figure 3 the cleaning head 100 further comprises a frame part 119. When the main body 110 is mounted on the cleaning head, the frame part 119 and the main body 110 have a common overlap in the direction extending along the longitudinal axis L of the roller brush 130, to ensure the stability and air tightness of the overall structure.

[0050] In one example, as shown in Figure 3 , Figure 5 and Figure 6As shown, the frame portion 119 includes an opening 119A formed therein, which is in flow communication with the air passage on the connecting portion 120 to provide a gas flow path from the opening 119A to the air passage. The main body portion 110 has an opening 119B formed in a position corresponding to the opening 119A in the area of the overlap of the shell 111 and the frame portion 119 to provide a gas flow path in communication with the opening 119A. In this way, when the cleaning head is in operation, the gas flow with the dirt particles entrained is directed through the suction opening 114, the opening 119A and the opening 119B to the air passage on the connecting portion 120, thereby facilitating the recovery of the dirt particles by the surface cleaning apparatus.

[0051] In the description of the specification, the description of the terms "one example / way", "some examples / ways", "example", "specific example", or "some examples" and the like means that the specific features, structures, materials or characteristics described in connection with the example / way or example are included in at least one example / way or example of the present application.
