[0029] Please refer to Figure 1 、 Figure 2 and Figure 3 As shown in, this embodiment provides a brush 120 for installation at the suction port 111 of a vacuum cleaner, including a brush body 121 and a brush head 122 provided on the brush body 121. The brush body 121 has a ventilation channel 1211. The two ends of the brush body 121 are respectively a connection end 1212 and an operating end 1213. The connection end 1212 is connected to the suction port 111. The operating end 1213 has an opening 1213a communicating with the ventilation channel 1211. The brush head 122 is provided at the operating end 1213.
[0030] Specifically, when using the brush 120 of the present application, the brush 120 is installed at the suction port 111 of the vacuum cleaner. First, the sticky foreign objects are removed by the brush head 122 provided at the operating end 1213. Then, the vacuum cleaner is turned on, and the opening 1213a at the operating end 1213 is aligned with the foreign objects. The foreign objects are sucked into the ventilation channel 1211 through the opening 1213a by the suction of the vacuum cleaner and conveyed to the vacuum cleaner through the ventilation channel 1211. During the cleaning process, there is no need to replace accessories. By installing the brush 120 that combines the functions of dust suction and the brush head 122, the cleaning of foreign objects is made more convenient.
[0031] The brush 120 provided by the present application is for installation at the suction port 111 of a vacuum cleaner, including a brush body 121 and a brush head 122 provided on the brush body 121. The brush body 121 has a ventilation channel 1211. The two ends of the brush body 121 are respectively a connection end 1212 and an operating end 1213. The connection end 1212 is connected to the suction port 111. The operating end 1213 has an opening 1213a communicating with the ventilation channel 1211. The brush head 122 is provided at the operating end 1213. During the cleaning process, there is no need to replace accessories. By installing the brush 120 that combines the functions of dust suction and the brush head 122, the cleaning of foreign objects is made more convenient.
[0032] In a feasible embodiment of the present application, as shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the brush head 122 includes a mounting base 1221 and bristles 1222 provided on the mounting base 1221. The brush head 122 is connected to the working end 1213 through the mounting base 1221.
[0033] Specifically, the mounting base 1221 of the present application is provided on the working end 1213. First, the mounting base 1221 is detachably mounted on the working end 1213 of the brush body 121. When the bristles 1222 of the brush head 122 are severely worn and need to be replaced, the mounting base 1221 can be removed from the working end 1213 and a new brush head 122 can be installed.
[0034] Exemplarily, the mounting base 1221 can be installed at the opening 1213a of the working end 1213 and partially cover the opening 1213a to ensure that the brush 120 combines the functions of dust suction and the brush head 122.
[0035] Another exemplarily, the mounting base 1221 can be installed on the periphery of the opening 1213a of the working end 1213 to ensure that the brush 120 combines the functions of dust suction and the brush head 122.
[0036] In a feasible embodiment of the present application, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the mounting base 1221 is rotatably connected to the opening 1213a through a rotating shaft 1223, so that the bristles 1222 on the mounting base 1221 have a working state of leaking outside the ventilation channel 1211 and an idle state of being received in the ventilation channel 1211.
[0037] Specifically, the mounting base 1221 is rotatably mounted at the opening 1213a through the rotating shaft 1223, so that the bristles 1222 on the mounting base 1221 have a working state of leaking outside the ventilation channel 1211 and an idle state of being received in the ventilation channel 1211. When using the brush 120 of the present application for operation, first rotate the mounting base 1221 so that the bristles 1222 on the mounting base 1221 are in the working state of leaking outside the ventilation channel 1211, and brush off the sticky foreign matters on the ground through the bristles 1222. Subsequently, rotate the mounting base 1221 so that the bristles 1222 are in the idle state of being received in the ventilation channel 1211, align the opening 1213a with the foreign matters, and suck the foreign matters into the ventilation channel 1211 through the opening 1213a by the suction force of the vacuum cleaner, and convey them to the vacuum cleaner through the ventilation channel 1211.
[0038] When the vacuum cleaner only needs to adsorb sundries, rotate the mounting base 1221 so that the bristles 1222 are in the idle state of being received in the ventilation channel 1211, so that the opening 1213a can better adhere to the working surface, and the cleaning effect of the vacuum cleaner is better.
[0039] In a feasible embodiment of the present application, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the ventilation channel 1211 includes a connecting section 1211a and a flared section 1211b that are interconnected. The connecting end 1212 is disposed on the connecting section 1211a, and the working end 1213 is disposed on the flared section 1211b.
[0040] Specifically, the ventilation channel 1211 is set to include a connecting section 1211a and a flared section 1211b, and the working end 1213 is disposed on the flared section 1211b. That is, the brush 120 and the opening 1213a are disposed on the flared section 1211b. That is, the area of the opening 1213a and the area of the brush 120 are increased, so as to enhance the cleaning efficiency of the brush 120.
[0041] Exemplarily, the opening 1213a is opened on the flared section 1211b. The mounting seat 1221 is rotatably mounted at the opening 1213a through a rotating shaft 1223 to partially cover the opening 1213a, so that the brush 120 has the functions of both dust suction and foreign object brushing. The rotating shaft 1223 is disposed in the middle of the opening 1213a. The mounting seat 1221 is flipped through the rotating shaft 1223 to enable the bristles 1222 to have a working state of leaking out of the ventilation channel 1211 and an idle state of being received in the ventilation channel 1211.
[0042] In a feasible embodiment of the present application, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the working end 1213 is provided with a clamping edge 1213b or an elastic limiting point, and the mounting seat 1221 is provided with a clamping plate 1221a that is in interference clamping with the clamping edge 1213b or the elastic limiting point. When the bristles 1222 are in the idle state, the clamping plate 1221a is clamped with the clamping edge 1213b or the elastic limiting point.
[0043] Specifically, when the vacuum cleaner only needs to adsorb sundries, the mounting seat 1221 is rotated until the clamping plate 1221a is clamped with the clamping edge 1213b or the elastic limiting point, so that the bristles 1222 are in the idle state of being received in the ventilation channel 1211, avoiding the mounting seat 1221 from flipping during the air extraction process and affecting the dust suction effect, enabling the opening 1213a to better adhere to the working surface, and making the cleaning effect of the vacuum cleaner better.
[0044] In a feasible embodiment of the present application, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a holding portion 1221b that abuts against the side wall of the ventilation passage 1211 is provided on one side of the mounting base 1221. When the brush bristles 1222 are in the working state, the holding portion 1221b abuts against the side wall of the ventilation passage 1211.
[0045] Specifically, a clamping protrusion 1212a is provided inside the opening 1213a, and a clamping groove is provided on the mounting base 1221. When the holding portion 1221b abuts against the side wall of the ventilation passage 1211, the clamping protrusion 1212a is engaged with the clamping groove, so as to prevent the mounting base 1221 from rotating relative to the opening 1213a when the brush bristles 1222 are in the working state, resulting in an unstable working state of the brush head 122.
[0046] When using the brush 120 of the present application for operation, first rotate the mounting base 1221 until the clamping plate 1221a is engaged with the clamping edge 1213b, so that the brush bristles 1222 on the mounting base 1221 are in a working state of being exposed outside the ventilation passage 1211, preventing the mounting base 1221 from flipping during the air extraction process, which affects the dust collection effect, enabling the opening 1213a to better adhere to the working surface, and making the cleaning effect of the vacuum cleaner better. The sticky foreign matters on the ground are brushed off by the brush bristles 1222, and then by rotating the mounting base 1221, the holding portion 1221b abuts against the side wall of the ventilation passage 1211, so that the brush bristles 1222 are in an idle state of being received in the ventilation passage 1211. The opening 1213a is aligned with the foreign matters, and the foreign matters are sucked into the ventilation passage 1211 through the opening 1213a by the suction of the vacuum cleaner and are conveyed to the vacuum cleaner through the ventilation passage 1211.
[0047] In a feasible embodiment of the present application, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, a notch 1221c is provided on the mounting base 1221, and the notch 1221c communicates with the opening 1213a.
[0048] Specifically, a notch 1221c is provided on the mounting base 1221, and the notch 1221c is provided on the side close to the rotating shaft 1223 to increase the size of the opening 1213a, thereby enhancing the suction volume of the vacuum cleaner.
[0049] It should be noted that the notch 1221c is opened on the side of the mounting base 1221 close to the rotating shaft 1223, and the brush bristles 1222 are arranged around the notch 1221c to ensure the air intake volume of the opening 1213a and the brushing area of the brush bristles 1222.
[0050] In a feasible embodiment of the present application, as Figure 1 、 Figure 2 and Figure 5As shown in the figure, a handheld vacuum cleaner 100 is provided, which includes a vacuum cleaner main body 110 and a brush 120 as described in any one of the above. The vacuum cleaner main body 110 has a suction port 111 and an air outlet 112, and the brush 120 is detachably installed at the suction port 111.
[0051] Specifically, when using the handheld vacuum cleaner 100 of the present application, the brush 120 is installed on the vacuum cleaner main body 110, the opening 1213a of the working end 1213 of the brush 120 is aligned with the foreign object, and the foreign object is sucked into the ventilation channel 1211 through the opening 1213a by the suction force of the vacuum cleaner, and is conveyed to the vacuum cleaner through the ventilation channel 1211. During the cleaning process, there is no need to replace accessories. By installing the brush 120 that combines the functions of dust suction and the brush head 122, the cleaning of foreign objects is made more convenient.
[0052] In a feasible embodiment of the present application, as Figure 1 、 Figure 2 and Figure 5 shown, an installation groove 1111 is provided on the inner wall of the suction port 111, and a clamping protrusion 1212a that is clamped with the installation groove 1111 is provided on the outer wall of the connection end 1212 of the brush 120.
[0053] Specifically, when installing the brush 120 on the vacuum cleaner main body 110, the clamping protrusion 1212a on the outer wall of the connection end 1212 of the brush 120 is clamped with the installation groove 1111 on the inner wall of the suction port 111 to ensure that the brush 120 does not detach from the suction port 111 during the suction process.
[0054] Furthermore, a marble assembly 1112 is provided in the installation groove 1111, and a groove 1212b that is clamped with the marble assembly 1112 is provided on the clamping protrusion 1212a.
[0055] When installing the brush 120 on the inner wall of the suction port 111, first, the clamping protrusion 1212a on the outer wall of the connection end 1212 of the brush 120 is clamped with the installation groove 1111 on the inner wall of the suction port 111. When the clamping is in place, the marble assembly 1112 in the installation groove 1111 will snap into the groove 1212b on the clamping protrusion 1212a, so that the brush 120 can be stably clamped.
[0056] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
