[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0027] Embodiment 1

[0028] Based on the existing prior art brush handle length and angle fixed, it is inconvenient to use in daily cleaning process and there is the problem of cleaning dead angle, the embodiment provides a brush convenient for adjusting handle, please refer to Figures 1-4 , the embodiment provides a brush convenient for adjusting handle, which can adjust the brush handle according to the cleaning environment. The brush convenient for adjusting handle includes the brush head 2 installed at the end of the handle 1, the adjusting mechanism 3 for adjusting the cleaning angle and length of the handle is arranged on the handle 1, the angle of the brush head 2 is adjusted through the adjusting mechanism 3, so that the dust in the corner gap is cleaned, and then the rotating cleaning assembly 34 drives the brush head 2 to rotate, so that the corner gap is cleaned, and then the length of the handle 1 is adjusted through the extension assembly 35, so that the cleaning range is extended.

[0029] Due to the fixed length and angle of the brush handle in the prior art, it is inconvenient to use in daily cleaning process and there are cleaning dead angles, so the device is provided with an adjusting mechanism 3, the adjusting mechanism 3 includes a ball head seat 31 installed at the end of the handle 1, and a ball head 32 is rotatably connected in the ball head seat 31, and the other side of the ball head 32 is connected with the brush head 2, and a positioning bolt 33 is threadedly connected in the threaded holes opened through the front and rear sides of the ball head seat 31, and a rotating cleaning assembly 34 for driving the brush head 2 to rotate to clean the corner gap is arranged between the ball head seat 31 and the handle 1, and an extension assembly 35 for adjusting the length of the handle 1 is arranged on the handle 1, when there is a certain arc in the corner gap, the positioning bolt 33 is loosened first, then the brush head 2 is rotated to drive the ball head 32 to rotate in the ball head seat 31 to adjust the cleaning angle of the brush head 2, after the angle adjustment is completed, the positioning bolt 33 is tightened to abut against the ball head 32 and fix it in the ball head seat 31, so that the adjustment and fixation of the cleaning angle of the brush head 2 are realized.

[0030] Due to the fixed length of the handle of the existing brush, it cannot be cleaned when encountering a higher place or a deeper gap, so the device is also provided with an extension assembly 35, the extension assembly 35 includes a sliding hole 351 opened on the handle 1, and an extension rod 352 is slidably connected in the sliding hole 351, and an end cover 353 is installed at the right end of the extension rod 352, a fixed hole 354 is opened on the handle 1 and communicates with the sliding hole 351, a spring cavity 355 is opened in the fixed hole 354, and a fixed plug 356 is slidably connected in the fixed hole 354, and a compression spring 357 is sleeved on the fixed plug 356 and installed in the spring cavity 355.

[0031] A plurality of fixed holes 354 are also arrayed on the side surface of the extension rod 352, when it is necessary to lengthen the handle 1, the fixed plug 356 is pulled backward to slide out of the fixed hole 354 and compress the compression spring 357, then the end cover 353 is pulled to slide the extension rod 352 out of the sliding hole 351 to the required length, then the fixed plug 356 is sent out, and under the elastic driving of the compression spring 357, it is reinserted into the fixed hole 354 on the extension rod 352, so that the adjustment and fixation of the length of the handle 1 are completed to adapt to different cleaning scenes and improve the application range of the brush.

[0032] In order to avoid the rotation of the extension rod 352 when it slides out, causing the fixed plug 356 and the fixed hole 354 to be misaligned, the device is provided with a guide sliding groove opened on the side wall of the sliding hole 351, and a guide strip 358 is slidably connected in the guide sliding groove and installed on the extension rod 352, when the extension rod 352 slides out of the sliding hole 351, the guide strip 358 on the extension rod 352 slides out of the guide sliding groove, so that the extension rod 352 is prevented from rotating, causing the fixed plug 356 and the fixed hole 354 to be misaligned.

[0033] Embodiment 2

[0034] Based on Example 1, such as Figures 1-4 As shown, due to the limited space in some corners and crevices, it is not convenient to exert force to thoroughly clean these areas. Therefore, the device is also equipped with a rotating cleaning component 34. The rotating cleaning component 34 includes a bearing 341 installed in a rotating hole at the end of the handle 1, and a rotating rod 342 rotatably connected to the bearing 341 on the side of the ball head seat 31. A bevel gear 343 is installed on the rotating rod 342, and a drive bevel gear 344 is meshed with the outer side of the bevel gear 343. A connecting rod 345 is installed on the drive bevel gear 344, and the connecting rod 345 is rotatably connected to a support bushing 346 installed on the side of the handle 1. After the brush head 2 is inserted into the crevices, the connecting rod 345 is rotated, thereby driving the drive bevel gear 344 to rotate, which in turn drives the bevel gear 343 to rotate, which in turn drives the rotating rod 342 to rotate within the bearing 341, thereby driving the brush head 2 to rotate and thoroughly clean the corners and crevices, making it more labor-saving and convenient.

[0035] Multiple support bushings 346 are arrayed and installed on the side of the handle 1. A turntable 347 is installed at the end of the connecting rod 345, and anti-slip protrusions are installed on the turntable 347. The anti-slip protrusions on the turntable 347 make it easier for the user to apply force to rotate the connecting rod 345.

[0036] It should be noted that, in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
