[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In the field of household and commercial cleaning, the row brush is an important cleaning tool, widely used in cleaning floors, walls and other surfaces. As consumers' requirements for the performance of cleaning tools increase, the limitations of traditional fixed row brushes are gradually revealed, especially when cleaning irregular surfaces, small gaps and difficult locations. Therefore, it is particularly important to develop a highly adjustable row brush.

[0031] Embodiment 1:

[0032] The surfaces to be cleaned often vary in shape, such as uneven walls, corners, the bottom of furniture, etc. In order to solve the above problems, Figure 1-Figure 3As shown, the adjustable brush provided by the present invention comprises a housing, a brush is provided at the bottom of the housing, a hand-held component is provided on the housing, and an adjustment component for adjusting the angle of the brush is provided on the housing. The user can easily adjust the angle of the brush according to different cleaning tasks and usage scenarios. This makes the cleaning work more efficient, especially when cleaning hard-to-reach areas. A cleaning component for cleaning impurities on the brush is also provided, which can quickly clean impurities on the brush and save more time and energy. No other tools or manual processing are required, making the overall cleaning process smoother.

[0033] When cleaning different types of surfaces (such as walls, furniture, floors, etc.), the lack of adjustable angles limits the scope of application of the tool and cannot be optimized for different tasks. In order to solve the above problems, the adjustment component includes a frame, a transmission shaft is rotatably mounted on the frame, a transmission frame is mounted on the transmission shaft, and the outer shell is fixed to the transmission frame. The two sides of the frame are designed with openings. When the brush angle needs to be adjusted, the transmission shaft rotates to drive the transmission frame to rotate, and the outer shell moves with the transmission frame, so that the angle of the brush on the outer shell can be adjusted, which can provide a smooth operating experience. By rotating the transmission shaft, the brush angle can be conveniently adjusted, and users can achieve quick and smooth adjustments without any effort.

[0034] Since the brush itself is a cleaning tool, it is rather troublesome to use electric angle adjustment. In order to solve the above problem, a rotating rod is rotatably installed on the frame, a worm is mounted on the rotating rod, and a worm wheel meshing with the worm is mounted on the transmission shaft. When the rotating rod is rotated, the worm rotates with the rotating rod, and the worm drives the transmission shaft to rotate through the worm wheel, thereby adjusting the angle of the brush on the outer shell. No electric components are required, and the brush angle can be adjusted manually. In addition, the worm and worm wheel have a self-locking function.

[0035] People's heights vary greatly, and fixed-height brushes may not be suitable for all users. For shorter people, the fixed high position may be difficult to reach, and for taller people, the low-position brush may not be able to effectively clean, resulting in inconvenience in use. In order to solve the above problems, the handheld assembly includes a connecting rod fixed to the frame, a threaded groove is provided on the upper part of the connecting rod, and a sliding sleeve is threadedly connected to the threaded groove. When the height distance between the brush and the user needs to be adjusted, the sliding sleeve is rotated to move on the connecting rod through the threaded groove, so that the use height of the brush can be adjusted.

[0036] The sliding sleeve is provided with a protective pad, which is made of a flexible material. The provision of the protective pad can improve the comfort of the user when using the device.

[0037] According to the embodiment, by adjusting the angle of the brush, the user can make the brush fit the cleaning surface better, thereby improving the cleaning effect. For example, when cleaning the gaps or corners of tiles, the angle adjustment can effectively remove dirt.

[0038] Embodiment 2:

[0039] Different cleaning tasks may require different bristle lengths. Unadjustable bristles may not be effective in dealing with stubborn dirt or cleaning small gaps, resulting in incomplete cleaning. In order to solve the above problems, combined with Figure 5 and Figure 6 As shown, on the basis of the first embodiment, a connecting plate is fixedly connected to the brush, the connecting plate is slidably connected to the inner cavity of the shell, a plurality of vertically distributed slots are opened in the shell, a pillar is fixedly connected to the connecting plate, a transmission sleeve is fixedly connected to the pillar, a transmission sheet is slidably connected to the transmission sleeve, a spring 1 is fixedly connected between the transmission sheet and the inner wall of the transmission sleeve, a transmission bar is fixedly connected to the transmission sheet and slidably connected to the transmission sleeve, a block corresponding to the slot is fixedly connected to the end of the transmission bar, a handle is fixedly connected to the other end of the transmission bar, and the end of the transmission sleeve extends to the outside of the shell through the slide slot. When it is necessary to adjust the extended length of the brush at the shell, the handle is held by hand, and then the transmission bar is pulled by the handle to drive the block to move, and the block is disengaged from the slot. Then, the position of the brush is moved according to the usage, and then the handle is released. The spring pushes the transmission sheet to move, and the transmission bar moves with the transmission sheet, driving the block on the transmission bar to move, so that the block is inserted into the slot, thereby controlling the extended length of the bristles on the brush at the shell. The length of the brush can be adjusted according to the requirements of different cleaning tasks and surfaces to ensure the best effect during cleaning. For example, for deep cleaning or cleaning tight spaces, a longer brush can be used, while for tight areas, a shorter brush length can be used.

[0040] Specifically, the transmission frame is a U-shaped structure, and the transmission frame does not contact the frame and the worm, which can avoid the transmission frame from contacting the frame and the worm when rotating, and prevent the transmission frame from getting stuck when transmitting.

[0041] Furthermore, the end of the rotating rod extends to the upper part of the frame, and the rotating rod is rotatably connected to the frame through a bearing.

[0042] According to the embodiments, different cleaning objects (such as floors, walls, furniture, etc.) may require brushes of different lengths. The adjustable length design enables the brush to adapt to a variety of surfaces and situations, thereby improving its versatility.

[0043] Embodiment three:

[0044] When the brush is entangled with hair, the user needs to clean the bristles by hand, otherwise the cleaning effect will be affected. The user cleans by hand during use, which reduces the user's experience. In order to solve the above problem, a method is combined with Figure 3 and Figure 4As shown, on the basis of embodiment 1, the cleaning component includes a limiting groove opened on the shell, a slider is slidably connected to the limiting groove, a spring 2 is fixedly connected between the slider and the bottom wall of the limiting groove, a transmission plate is fixedly connected to the end of the slider, a cleaning claw plugged with the brush is fixedly connected to the bottom of the transmission plate, and a pedal is fixedly connected to the transmission plate. When the brush is cleaning hair or floc-like or filamentous garbage, the hair will be entangled on the brush. At this time, the pedal is stepped on to make it lower, and the transmission plate moves with the pedal, which can then drive the cleaning claw on the transmission plate to move, and the cleaning claw cleans the garbage on the brush. The operation is simple, and the user can clean the brush without bending over, thereby further improving the user's experience.

[0045] It can be seen from the above embodiments that: first, the user adjusts the distance between the brush and his or her arm according to his or her height, and rotates the sliding sleeve to make it move on the connecting rod through the threaded groove, so as to adjust the use height of the brush. After the adjustment is completed, the angle of the brush is adjusted according to the use scenario, and the rotating rod is rotated. The worm rotates with the rotating rod, and the worm drives the transmission shaft to rotate through the worm gear, and then the angle of the brush on the shell can be adjusted, and then the user can use the brush.

[0046] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
