DETAILED DESCRIPTION

[0024] To describe the technical content, structural features, achieved purpose and effect of the utility model in detail, the technical scheme in the embodiment of the present application will be described below in conjunction with the drawings in the embodiment of the present application. Obviously, the described embodiment is only a part of the embodiment of the present application, rather than all the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the utility model. However, various exemplary embodiments may also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments may be different, but not necessarily exclusive. For example, without departing from the concept of the utility model, the specific shape, structure and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0025] An embodiment of the present application provides a floating brush tool for a vacuum cleaner. The floating brush tool is connected to the vacuum cleaner to clean a surface to be cleaned, and is particularly suitable for cleaning objects with irregular surfaces.

[0026] like Figure 1 , 2 As shown in Figures 4, the floating brush tool 100 includes an outlet connecting pipe 1 connected to a vacuum cleaner, a shell 2 with a suction chamber 201 defined therein, and a plurality of micro brush heads 3 mounted on the shell 2, the outlet connecting pipe 1 being fluidically connected to the suction chamber 201, the shell 2 having a bottom wall 203 facing the surface to be cleaned, each micro brush head 3 being mounted on the shell 2 with at least a portion of the micro brush head 3 protruding downward from the bottom wall 203, and each micro brush head 3 being provided with a suction port 301 connected to the suction chamber 201; the plurality of suction ports 301, the suction chamber 201 and the outlet connecting pipe 1 are sequentially connected to form a suction channel for transporting dust on the surface to be cleaned to the vacuum cleaner.

[0027] like Figure 1 , 3As shown in Figure 5, the shell 2 includes an upper shell 21, a lower shell 22 and a partition 23 arranged between the upper shell 21 and the lower shell 22, and the bottom wall 203 is defined by the lower shell 22; the upper shell 21 and the lower shell 22 are joined up and down to define an accommodating space, and at least part of each micro brush head 3 and the partition 23 are installed in the accommodating space. The partition 23 defines a suction chamber 201 with the upper shell 21 in the accommodating space, and defines an installation chamber 202 with the lower shell 22.

[0028] like Figure 3 , 5 As shown, the lower shell 22 and the partition 23 are provided with through holes for each micro brush head 3 to pass through in the up-down direction. Each micro brush head 3 is independently supported on the partition 23 by a spring 4. Each micro brush head 3 is configured to work independently without affecting each other. Multiple springs 4 respectively configured with multiple micro brush heads 3 are all accommodated in the installation cavity 202. Each micro brush head 3 can be installed on the shell 2 in a floating manner in the up-down direction through the corresponding spring 4. Each floating micro brush head 3 has a first limiting portion 31 and a second limiting portion 32 protruding radially outward. The first limiting portion 31 and the second limiting portion 32 are arranged opposite to each other in the upper and lower directions, and the outer diameters of the first limiting portion 31 and the second limiting portion 32 are both larger than the diameter of the through hole. The first limiting portion 31 is located in the suction cavity 201, and the second limiting portion 32 is located in the installation cavity 202. The first limiting portion 31 and the second limiting portion 32 can prevent each micro brush head 3 from sliding out of the shell 2 through the corresponding through hole. The head and tail ends of the spring 4 are respectively abutted between the second limiting portion 32 and the partition 23. The part of the micro brush head 3 protruding from the bottom wall 203 can be retracted into the accommodating space when subjected to external force. When the external force is lost, the spring 4 pushes the micro brush head 3 to extend to the lower side of the bottom wall 203 to reset.

[0029] Each micro brush head 3 has a protrusion 33 protruding downward from the bottom wall 203, and the protrusion 33 has a lower end surface 331 facing the surface to be cleaned; each micro brush head 3 is provided with an air flow channel 302 connected to the suction chamber 201, and the end of each air flow channel 302 forms a suction port 301 on the lower end surface 331; Figure 1 As shown, each protrusion 33 is also provided with one or more friction elements, and the one or more friction elements are arranged around the suction port 301; in the embodiment of the present application, the one or more friction elements are made of soft rubber material, and the floating micro brush head 3 and the flexible friction element can adapt to the uneven surface of the object to be cleaned and better fit the surface of the object.

[0030] Continue to refer to Figure 3 and Figure 5Each micro brush head 3 includes a hollow brush head body 34 and a soft rubber member 35 covering the lower end of the brush head body 34. The brush head body 34 is columnar, and the first limiting portion 31, the second limiting portion 32, the protruding portion 33 and the air flow channel 302 are all limited on the brush head body 34. The soft rubber member 35 of each micro brush head 3 has a plurality of protrusions 351, and the plurality of protrusions 351 form one or more friction elements. Each protrusion 351 protrudes downward from the lower end surface 331 and is distributed at intervals along the circumference of the suction port 301. When the micro brush head 3 contacts the surface to be cleaned, it contacts the surface to be cleaned by friction, and gaps connected to the suction port 301 are formed between adjacent protrusions 351; the protrusions 351 ensure that the plurality of micro brush heads 3 of the floating brush tool 100 can better fit the surface to be cleaned, and ensure the normal suction work of the suction port 301 on the other hand.

[0031] like Figure 1 , 4 As shown, the bottom wall 203 of the housing 2 is rectangular and has a length direction and a width direction, and a plurality of micro-motion brush heads 3 are arranged in an array along the length direction and the width direction.

[0032] When the floating brush tool 100 is used for cleaning operations, the lower ends of multiple micro brush heads 3 are placed on the surface to be cleaned, and the micro brush heads 3 are attached to the surface to be cleaned. The outward protruding parts of the surface to be cleaned push the corresponding micro brush heads 3 upwards, and when the corresponding micro brush heads 3 move out of the protruding parts, they are immediately pushed back by the springs 4.

[0033] The present application also provides a vacuum cleaner equipped with the floating brush tool 100 in the above-mentioned embodiment, the vacuum cleaner includes a vacuum main unit and an air inlet pipe, the air inlet pipe is connected to the outlet connecting pipe 1 so that the floating brush tool 100 can be installed as a whole on the vacuum main unit, the vacuum main unit includes a suction motor and a dust collecting device, the suction motor and the dust collecting device are both fluidically connected to the air inlet pipe, the suction motor forms a suction negative pressure at multiple suction ports 301 of the floating brush tool 100 through the air inlet pipe, so that the dust on the surface to be cleaned enters the dust collecting device through the suction port 301, the air flow channel 302, the suction chamber 201, the outlet connecting pipe 1 and the air inlet pipe in sequence to achieve cleaning.

[0034] The multiple independently floating micro brush heads of the present application can be extended and retracted according to the surface curvature of the object to be cleaned, so that the floating brush tool can better fit the surface to be cleaned, and the floating brush tool can be quickly adjusted according to the curvature of the surface to be cleaned during movement, thereby increasing the surface area of ​​contact between the brush head and the cleaning object and achieving a better cleaning effect.
