[0022] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0023] The following is combined with Figure 1-Figure 3This embodiment will be described in further detail.

[0024] Please see Figure 1-Figure 2 This embodiment of an ergonomic brush handle includes an outer cylinder 100, an open telescopic cavity 200 inside the outer cylinder 100, a movable connecting post 130 extending out of the telescopic cavity 200, a shock-absorbing cavity 230 at the extended end of the connecting post 130, a brush head 140 extending out of the shock-absorbing cavity 230, and a buffer assembly for buffering the brush head 140 inside the shock-absorbing cavity 230. Multiple positioning holes 202 are evenly provided along the axial direction on the outer side wall of the connecting post 130. A through hole 210 is provided on the outer cylinder 100 corresponding to the positioning holes 202, and a control assembly is provided on the outer cylinder 100 corresponding to the through hole 210. The control assembly includes a positioning pin 112 that can extend into the corresponding positioning hole 202.

[0025] In this embodiment, a handle is formed between the outer cylinder 100 and the connecting post 130, and the brush head 140 is installed on the extended end of the connecting post 130. Thus, a brush is preferably formed. In actual use, the brush head 140 can be driven to perform brushing and cleaning by holding the handle. In actual use, the outer side of the outer cylinder 100 is provided with a grip part 101 that fits in contact with the palm. The grip part 101 is designed to facilitate the user's grip, thereby achieving the ergonomic design of this embodiment and making it more comfortable to use.

[0026] The movable arrangement of the connecting post 130 within the telescopic cavity 200 allows for adjustment of the extension distance of the connecting post 130, thereby enabling adjustment of the handle length. This facilitates the user's grip on the handle to drive the brush head 140 for brushing and cleaning, thus improving the applicability of the brush.

[0027] The buffer component allows the user to hold the handle and drive the brush head 140 to clean. When the brush head 140 hits the surface of the object, the buffer component can cushion the brush head 140 so that it will not break due to excessive force and affect subsequent normal use.

[0028] The extension and retraction of the connecting post 130 can be controlled by the control components. When the positioning pin 112 extends out of the positioning hole 202, the connecting post 130 can move within the telescopic cavity 200 to adjust the length of the connecting post 130 extending out of the telescopic cavity 200. When the positioning pin 112 extends into the positioning hole 202, the connecting post 130 can be fixed, thus fixing the length of the connecting post 130 extending out of the telescopic cavity 200, thereby fixing the length of the handle for easy use.

[0029] like Figure 1 and Figure 2As shown, in this embodiment, the telescopic cavity 200 is provided with a first spring 201 for driving the connecting column 130 to move outward; the control component includes connecting blocks 110 disposed on the outer side wall of the outer cylinder 100, and a control cavity is formed between the connecting blocks 110. A connecting shaft 111 is provided in the control cavity. The positioning pin 112 includes an L-shaped control rod 211. One end of the control rod 211 forms a positioning rod portion. The connecting shaft 111 passes through the control rod 211. A torsion spring for driving the positioning rod portion to extend into the corresponding positioning hole 202 is sleeved on the connecting shaft 111.

[0030] In this embodiment, the first spring 201 pushes the connecting post 130 to move out of the telescopic cavity 200, enabling the connecting post 130 to move automatically out of the telescopic cavity 200. Through the torsion spring, the control rod 211 can rotate around the connecting shaft 111. When the control rod 211 rotates, the positioning rod passes through the through hole 210 and extends into the corresponding positioning hole 202, thus fixing the connecting post 130. At this time, pressing the other end of the control rod 211 causes one end of the control rod 211 to tilt upwards, thus tilting the positioning rod and disengaging it. After removing the positioning hole 202 and releasing the fixing of the connecting post 130, the connecting post 130 is pushed out of the telescopic cavity 200 under the action of the first spring 201. Therefore, when adjusting the length of the handle, by pressing the other end of the control rod 211 and pushing the connecting post 130 to telescopically move within the telescopic cavity 200, the corresponding positioning hole 202 moves to the positioning pin 112. Releasing the control rod 211 allows the torsion spring to drive the positioning rod to penetrate the through hole 210 and extend into the positioning hole 202. The operation is simple and convenient.

[0031] The diameter of the through hole 210 is slightly larger than the diameter of the positioning hole 202. With this structure, it is easier for the control rod 211 to be raised so that the positioning rod part passes through the through hole 210 and extends into or out of the positioning hole 202.

[0032] In actual use, since the positioning holes 202 are evenly distributed along the axial direction of the connecting post 130 on the outer surface of the connecting post 130, when the positioning pin 112 extends into the positioning holes 202 at different positions, the extension length of the connecting post 130 can be controlled so that it can adapt to different usage requirements.

[0033] like Figure 1-Figure 3 As shown, in this embodiment, the sidewall of the telescopic cavity 200 is provided with a sliding groove 300 along its axial direction, and the connecting column 130 is provided with a sliding block 301 that moves within the corresponding sliding groove 300.

[0034] In this embodiment, by setting the sliding groove 300 and the sliding block 301, the connecting column 130 can only move along the sliding groove 300, so that the connecting column 130 will not rotate during the movement in the telescopic cavity 200, thereby ensuring that the positioning hole 202 is always aligned with the through hole 210, so that the positioning pin 112 can extend into the positioning hole 202 from the through hole 210.

[0035] like Figure 1-Figure 2 As shown, the opening of the telescopic cavity 200 is provided with a removable second sealing ring 120 for sealing it.

[0036] In this embodiment, the second plug ring 120 is threadedly connected to the outer cylinder 100, thereby achieving a detachable connection at the opening of the telescopic cavity 200. One end of the connecting post 130 extends through the second plug ring 120. At the same time, the second plug ring 120 can limit the sliding block 301, thereby preventing the connecting post 130 from completely detaching from the telescopic cavity 200.

[0037] like Figure 1-Figure 2 As shown, in this embodiment, the opening of the damping cavity 230 is provided with a detachable first blocking ring 131; the buffer assembly includes a movable plate 232 that is slidably disposed in the damping cavity 230, and the first blocking ring 131 through which one end of the brush head 140 passes is connected to the movable plate 232. The damping cavity 230 is also provided with a buffer spring 231 for buffering the movable plate 232.

[0038] In this embodiment, the first plugging ring 131 is threaded to the protruding end of the connecting post 130 and is used to seal the damping cavity 230, thereby enabling the installation and removal of the buffer assembly within the damping cavity 230.

[0039] The brush head 140 includes a brush rod connected to the moving plate 232 through the first blocking ring 131 at one end and brush bristles distributed on the extended end of the brush rod. The moving plate 232 and the shock-absorbing cavity 230 have matching rectangular cross sections. With this structure, when the moving plate 232 moves in the shock-absorbing cavity 230, it can only move along the axial direction of the shock-absorbing cavity 230 and will not rotate around the shock-absorbing cavity 230, thereby causing the brush head 140 to rotate and affecting the brush head 140 to perform brushing and cleaning.

[0040] The brush rod is threaded through the first sealing ring 131 and connected to the movable plate 232, so that the first sealing ring 131 can be fitted on the brush rod. The two ends of the buffer spring 231 abut against the bottom wall of the movable plate 232 and the shock-absorbing cavity 230, respectively, to push the movable plate 232 to fit against the first sealing ring 131. In actual use, rubber pads are provided at both ends of the buffer spring 231. The cooperation between the buffer spring 231 and the rubber pads can better buffer the movable plate 232, that is, buffer the brush head 140.

[0041] Working principle: When the length of the handle needs to be adjusted, press the other end of the control lever 211 to lift one end of the control lever 211, causing the positioning rod to disengage from the positioning hole 202. At this time, the drive connecting column 130 moves telescopically within the telescopic cavity 200, causing the corresponding positioning hole 202 to move to the positioning pin 112. Release the control lever 211, and the torsion spring will drive the positioning rod to penetrate the through hole 210 and extend into the positioning hole 202. The operation is simple and convenient.

[0042] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
