The terms "vertical," "horizontal," "left," "right" and similar expressions used in this specification are for illustrative purposes only.

[0026] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by technicians in the technical field of the present invention. The terms used in this specification are only for the purpose of describing specific embodiments and are not used to limit the present invention. The terms "and / or" used in this specification include any and all combinations of one or more related listed items.

[0027] The present application embodiment provides a cleaning accessory 1 for a dust removal device (hereinafter directly described as the cleaning accessory 1), see Figures 1 to 4 The cleaning accessory 1 includes a base 100 and a cleaning element 200. The base 100 is used to be installed on the output shaft 22a. The base 100 is provided with a storage chamber 110. The storage chamber 110 is used to store cleaning materials. The storage chamber 110 has a powder outlet 111 connected to the outside. The cleaning element 200 is fixed to the base 100, and the cleaning element 200 can clean the surface to be cleaned by moving. When the cleaning accessory 1 rotates, the movement path of the powder outlet 111 and the movement path of the cleaning element 200 at least partially overlap.

[0028] For the above base 100, see Figures 1 to 4The base 100 includes a first base 120, a connecting body 130 and a second base 140 connected in sequence. The first base 120 is a cylindrical ring structure. The first base 120 is coaxially provided with a cylindrical suction hole 121. The second base 140 is a cylindrical structure, and the outer contour diameter of the second base 140 is smaller than the outer contour diameter of the first base 120. A mounting shaft 141 is provided on the side of the second base 140 away from the first base 120. The connecting body 130 is a rod structure, and the connecting body 130 is set at an angle of 20° with the axis of the first base 120. The number of connecting bodies 130 is 3, and the 3 connecting bodies 130 are arranged in a circular array around the axis of the first base 120. One end of the connecting body 130 is connected to the first base 120, and the other end is connected to the second base 140. When the user uses the cleaning accessory 1 , after starting the cleaning accessory 1 , the garbage swept by the cleaning part passes through the suction hole 121 of the first base body 120 , and then goes around the side of the second base body 140 and is sucked into the suction port 21 a 1 . The structural setting of the base 100 facilitates the suction of the swept garbage into the dust removal device. The garbage does not need to go around the outside of the first base 120 and then be sucked into the dust chamber. Because the outside of the first base 120 deviates from the dust suction port 21a1, the suction force here is relatively small, and the garbage is not easily sucked into the dust removal device. However, the present application does not limit the specific structure of the base 100. In the embodiment provided in the present application, the outer contours of the first base 120 and the second base 140 and the suction hole 121 are all set to be cylindrical so that the cleaning accessory 1 can run more smoothly during the rotation cleaning process, and the dust removal device can have a more balanced suction force when sucking in the garbage swept by the cleaning accessory 1. However, the present application does not limit the specific shapes of the first base 120 and the second base 140. In other embodiments of the present application, the outer contours of the first base 120 and the second base 140 and the suction hole 121 are limited. In other embodiments of the present application, the outer contours of the first base 120 and the second base 140 and the suction hole 121 can also be elliptical or polygonal such as a triangle, rectangle, or hexagon. It should be understood that in the embodiment of the present application, the connecting body 130 is set at an angle of 20° with the axis of the first substrate 120 in order to reduce the outer diameter of the second substrate 140 while reasonably avoiding the air flow channel while ensuring the connection strength between the first substrate 120 and the second substrate 140, but the present application does not make specific limitations on this. In some embodiments of the present application, the angle between the axis of the connecting body 130 and the first substrate 120 may be 35°, 40° or 53°, etc., or in some embodiments, the outer diameters of the first substrate 120 and the second substrate 140 are the same. In this case, the connecting body 130 may be set perpendicular to the first substrate 120, that is, the angle between the axis of the connecting body 130 and the first substrate 120 is 0°.It should also be understood that the number of connectors 130 is for the overall strength of the base 100 and the spatial avoidance of the air flow channel, but the present application does not limit the specific shape and number of the connectors 130. In other embodiments of the present application, the number of connectors 130 can also be 2 or 5 or more, and the multiple connectors 130 are distributed in a circular array around the axis of the first substrate 120, or while ensuring the connection strength between the first substrate 120 and the second substrate 140, the number of connectors 130 can be set to only 1.

[0029] For the first substrate 120, see Figures 1 to 4 The first base body 120 includes a hair implanting piece 122 and a material storage piece 123. Both the hair implanting piece 122 and the material storage piece 123 are annular columnar structures, and their cross-sectional profile shapes and sizes are the same. The hair implanting piece 122 and the material storage piece 123 are detachably installed by screwing.

[0030] The following describes the hair implanting part 122 and the material storage part 123 in sections.

[0031] For the above-mentioned hair implant 122, please refer to Figures 1 to 4 , the hair implant 122 is in the shape of a circular cylinder as a whole, the cleaning element 200 is fixed on the hair implant 122, and the hair implant 122 is provided with 5 cylindrical powder outlet holes 111, and the 5 powder outlet holes 111 are distributed in a circular array around the axis of the hair implant 122. It should be noted that the present application does not limit the specific shape and number of the powder outlet holes 111. In other embodiments of the present application, the cross-sectional shape of the powder outlet holes 111 can also be a polygon such as an ellipse, a triangle or a rectangle, and the number of powder outlet holes 111 can also be 2, 4, etc., or the powder outlet hole 111 can be directly set to 1 while ensuring the powder output. It should also be noted that in the embodiment of the present application, the 5 powder outlet holes 111 are distributed in a circular array around the axis of the hair implant 122 in order to make the powder output range more uniform, but the present application does not limit this. In other embodiments of the present application, the 5 powder outlet holes 111 can also be distributed in an uneven manner on the hair implant 122.

[0032] For the above-mentioned storage part 123, please refer to Figures 1 to 4The storage part 123 is an annular columnar structure, and a storage chamber 110 is provided in the storage part 123. The storage chamber 110 has an opening 112 on the side facing the hair implant 122. The hair implant 122 can block the opening 112 when it is installed on the storage part 123. The storage chamber 110 is used to contain powders such as carbon powder, talcum powder or fluff powder that can absorb grease. The powder can be released through the powder outlet 111 to the surface to be cleaned for cleaning. The setting of the storage part 123 allows the user to release the cleaning powder through the powder outlet 111 to assist in cleaning while cleaning the surface to be cleaned, thereby improving the user experience. It should be noted that the present application does not limit the type and function of the powder contained in the storage chamber 110. In other embodiments of the present application, the cleaning accessory 1 can also be used in other scenarios where powder needs to be applied to the working area, such as applying magnesium powder with water absorption to the working area. It should also be noted that in the embodiments of the present application, in order to simplify the structure and facilitate parts processing, the storage chamber 110 is arranged on the storage piece 123, but the present application is not limited to this. In other embodiments of the present application, the storage chamber 110 can also be arranged on the hair implantation piece 122, or the hair implantation piece 122 and the storage piece 123 are both provided with the storage chamber 110, so that the hair implantation piece 122 and the storage piece 123 can jointly enclose the storage chamber 110.

[0033] For the cleaning element 200 described above, see Figures 1 to 4The cleaning elements 200 are bristles, which are fixed on the bristle implant 122 in a clustered form, and the cross-sectional shape of each cluster of cleaning elements 200 is circular. There are multiple cleaning elements 200, and the multiple cleaning elements 200 are distributed in a circular array around the central axis of the base 100 in the form of 5 clusters of bristle groups. The cleaning elements 200 are arranged in clusters and at intervals to facilitate the dust removal device to suck in the garbage on the surface to be cleaned, and the garbage is not easy to get stuck between the cleaning elements 200. In the case of the same number of cleaning elements 200, the cleaning elements 200 are arranged in a single cluster to reduce the cross-sectional area of ​​the bristle group, and the user can also more easily clean the garbage attached to the cleaning elements 200. It should be supplemented that in other embodiments of the application, the cleaning element 200 can also be a sponge head or a silicone head, so as to remove the garbage attached to the surface to be cleaned or evenly apply the cleaning powder to the working surface. On the other hand, the purpose of achieving detachable installation between the hair implant 122 and the material storage member 123 by screw connection is to increase the connection area between the hair implant 122 and the material storage member 123, so as to achieve the sealing effect of the material storage chamber 110, but the present application does not limit this. In some embodiments of the present application, the hair implant 122 and the material storage member 123 can also be fixedly installed by other means such as clamping or bonding. It should also be noted that the cross-sectional shape of each cluster of cleaning elements 200 is set in a circular shape in order to make the movement process of the cleaning elements 200 smoother, but the present application does not limit this. In other embodiments of the present application, the cross-sectional shape of each cluster of cleaning elements 200 can be a polygon such as an ellipse, triangle or rectangle. It should also be noted that the present application does not limit the number of bristle groups. In other embodiments of the present application, the number of bristle groups can also be 2, 3 or 7, etc.

[0034] For further information, see Figure 5 , the powder outlet holes 111 and the bristle group are spaced and located on the circular contour line of the same diameter, and the cross-sectional diameter of the powder outlet holes 111 is the same as the cross-sectional diameter of the bristle group, the powder outlet holes 111 and the bristle group are located on the circular contour line of the same diameter, when the cleaning accessory 1 rotates for cleaning, the position where the powder outlet holes 111 discharge the powder overlaps with the motion trajectory of the cleaning element 200, and the user does not need to move the position of the cleaning accessory 1 according to the naked eye, and the bristles can contact and evenly spread the cleaning powder on the cleaning surface. It should also be noted that in the embodiment of the present application, the powder outlet holes 111 are arranged in a cylindrical shape and are evenly spaced with the bristle group in a number of 5, which can make the powder output of the cleaning accessory 1 more uniform, and the bristle group can also evenly spread the cleaning powder on the surface to be cleaned. However, the present application does not limit this. In other embodiments of the present application, the diameters of the circles of the powder outlet holes 111 and the bristle group array may be different, and the sizes and shapes of the powder outlet holes 111 and the bristle group may be different, so that the motion trajectories of the powder outlet holes 111 and the bristle group at least partially overlap and intersect.

[0035] On the other hand, in order to achieve a balanced coating effect, the number of powder outlet holes 111 and the number of bristle groups are the same, both being 5, and the powder outlet holes 111 and the bristle groups are arranged in sequence and at intervals, but the present application is not limited to this. In other embodiments of the present application, the powder outlet holes 111 and the bristle groups may not be arranged in sequence and at intervals, so that at least some of the powder outlet holes 111 and the bristle groups are arranged in sequence and at intervals.

[0036] Furthermore, in order to control the amount of powder discharged from the powder outlet 111, a powder amount control member (not shown) is provided at the position of the hair implant 122 corresponding to the powder outlet 111. The powder amount control member is a non-woven fabric, and the powder amount control member is bonded to the side of the hair implant 122 facing the storage member 123. The powder amount control member is used to block the powder in the storage chamber 110 from being released directly from the powder outlet 111, so that the user cannot control the amount of powder discharged, thereby causing waste or requiring additional cleaning of secondary garbage. The setting of the powder amount control member prevents the powder in the storage chamber 110 from being released directly from the powder outlet 111 without the action of external force. When the user needs powder for cleaning during use, the cleaning accessory 1 is knocked on the surface to be cleaned. The force on the powder will pass through the fiber holes inside the powder amount control member and then be released from the powder outlet 111 to the surface to be cleaned, thereby controlling the release speed of the powder outlet 111. It should be noted that, although the powder quantity control member is not shown in the embodiment of the present application, in order to facilitate the processing and assembly of the powder quantity control member, the powder quantity control member is configured in a circular shape and is adapted to the contour of the storage chamber 110, but the present application does not limit the specific shape of the powder quantity control member. For example, in some embodiments of the present application, the powder quantity control member can be in multiple circular shapes, and multiple powder quantity control members are individually fixed to the hair implant 122 and at least partially cover the powder outlet 111. It should also be noted that the present application does not limit the installation method of the powder quantity control member on the hair implant 122. For example, in other embodiments of the present application, the powder quantity control member can be set as a separate part directly assembled in the storage chamber 110, and the user needs to take out the powder quantity control member first when replenishing the powder. It should also be understood that in other embodiments of the present application, the specific material of the powder quantity control member can also be other fabrics with fiber meshes, such as knitted fabrics, so that the powder in the storage chamber 110 can seep out of the fabric under the action of external force, thereby achieving the purpose of controlling the powder output.

[0037] Preferably, in order to facilitate the installation of the cleaning accessory 1 on the output shaft 22a, the cleaning accessory 1 is provided with an installation chamfer 142 on the side of the second base 140 away from the first base 120. The installation chamfer 142 is conducive to the central alignment of the cleaning accessory 1 during installation, thereby facilitating the user's disassembly and replacement, thereby improving the user experience. The installation shaft 141 is also provided with an assembly chamfer 141a, which has a similar function to that of the above-mentioned installation chamfer 142, and will not be described in detail here.

[0038] Preferably, the mounting shaft 141 is made of magnetic material, and the end of the output shaft 22a is also provided with magnetic material, and the magnetism of the two is opposite. While the cleaning accessory 1 is installed by plug-in, it can also be detachably installed by magnetic attraction. Compared with the tight-fitting plug-in installation method, the installation and disassembly process of the magnetic assembly is more labor-saving and easy, and there is a feeling of being fully assembled during use.

[0039] The cleaning accessory 1 of the embodiment of the present application is provided with a material storage chamber 110 and a powder outlet hole 111. The user can install cleaning powder in the material storage chamber 110 and release it to the surface to be cleaned through the powder outlet hole 111 during cleaning, thereby allowing the user to directly use the cleaning powder to clean the working surface, which improves the cleaning efficiency.

[0040] The utility model also provides a dust removal device 2, see Figure 6 and Figure 7 The dust removal device 2 includes the above-mentioned cleaning accessory 1, a shell 21, a first driving source 22, a filtering module 23 and a second driving source 24. The shell 21 has a cavity 21a and a dust suction port 21a1 connecting the cavity 21a and the outside. The cleaning accessory 1 is arranged in the cavity 21a and partially extends out of the dust suction port 21a1, and the cleaning accessory 1 cleans the surface to be cleaned by movement. The first driving source 22 is arranged in the cavity 21a, and the cleaning accessory 1 is installed on the output shaft 22a of the first driving source 22, and the first driving source 22 is used to drive the cleaning accessory 1 to move. The filtering module 23 is arranged in the cavity 21a, and the filtering module 23 is used to filter solid waste from the airflow. The second driving source 24 is arranged in the cavity 21a, and the second driving source 24 is used to provide wind pressure so that external garbage can enter the cavity 21a through the dust suction port 21a1.

[0041] Since the dust removal device 2 of the embodiment of the present application includes the above-mentioned cleaning accessory 1, the dust removal device 2 of the embodiment of the present application has the beneficial effects of the above-mentioned cleaning accessory 1, which will not be described one by one here. The dust removal device 2 of the embodiment of the present application is equipped with a cleaning accessory 1, and the cleaning accessory 1 can drive the cleaning accessory 1 to rotate through the first driving source 22 while vacuuming, so that the swept garbage can be sucked into the dust removal device 2, and the cleaning powder in the cleaning accessory 1 can also be directly sucked into the dust removal device 2 after cleaning is completed, and the user does not need additional cleaning, and the cleaning force is strong and the operation is convenient.
