[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 and Figure 3 As shown, a defogging cleaning brush is used to clean car windshields, front and rear mirrors, mobile phone screens, TV screens, etc. It includes a base 1, a brush cloth 5, a connecting rod 2, and a linkage mechanism 3. The brush cloth 5 is installed on one side of the base 1 by means of Velcro or other detachable means. The detachable means are existing technology and will not be described in detail here. The brush cloth 5 is made of microfiber material, which has stronger water absorption and is soft and will not damage the screen. The connecting rod 2 can be a single straight rod or a telescopic rod, preferably a telescopic rod, which can be used by people with different arm lengths. One end of the connecting rod 2 is connected to the base 1 through the linkage mechanism 3 to realize the relative rotation of the two. The other end of the connecting rod 2 is equipped with a handle 4.

[0022] like Figure 1 As shown, it can be understood that the base 1 has an overall isosceles triangular structure, and the sharp corners are all treated with rounded transitions, which can improve safety and cleaning effect.

[0023] like Figure 3 and Figure 4As shown, the linkage mechanism 3 includes a first connecting member, a second connecting member 11, and a third connecting member 32. The first connecting member is connected to the connecting rod 2 and consists of a first bracket 33 and a second bracket 31. The first bracket 33 and the second bracket 31 are fixedly connected by bolts and nuts. A ball head 311 is integrally formed on the second bracket 31. The second connecting member 11 is fixedly connected to the side of the base 1 away from the brush cloth 5. The second connecting member 11 is provided with a first constraint groove 111 for accommodating the lower part of the ball head 311. The opening diameter of the constraint groove 111 is smaller than the diameter of the ball head 311; the third connector 32 is installed on the second connector 11 by fasteners, preferably the first screws. The second connector 11 is provided with a second constraint groove 322 for constraining the upper part of the ball head 311. The lower opening diameter of the second constraint groove 322 is larger than the diameter of the ball head 311, and the upper opening diameter of the second constraint groove 322 is smaller than the diameter of the ball head 311. By adjusting the tightness of the fasteners, the damping between the third connector 32 and the ball head 311 can be changed.

[0024] It is worth mentioning that, such as Figure 4 As shown, there are four first screws, and the four first screws are symmetrically distributed in pairs.

[0025] Understandably, during assembly, the lower part of the ball head 311 is first placed into the first constraint groove 111 of the second connector 11, and then the second constraint groove 322 of the third connector 32 passes through the second bracket 31 and covers the second connector 11, so that the upper part of the ball head 311 protrudes from the second constraint groove 322. Then, the first screw is tightened to fix the third connector 32 and the second connector 11 together. At this time, the ball head 311 is constrained in the cavity formed by the first constraint groove 111 and the second constraint groove 322.

[0026] Understandably, by adjusting the tightness of the first screw, the clamping force of the third connector 32 on the ball head 311 can be changed, thereby adjusting the damping required for rotation. This allows the base 1 to drive the brush 5 to rotate freely around the center point of the ball head 311, perfectly conforming to the various curves and corners of the cleaning surface, achieving thorough cleaning. In addition, the user can adjust the damping as needed, ensuring smoother adjustment while preventing accidental rotation between the base 1 and the ball head 311, thus improving the flexibility and cleaning efficiency of the brush 5.

[0027] As a preferred option, such as Figure 3 and Figure 4 As shown, a bracket cover 34 for covering the second connector 11 and the third connector 32 is installed on the base 1. A hook 341 is fixedly connected inside the bracket cover 34, and a locking block 321 for cooperating with the hook 341 is fixedly connected to the outer edge of the third connector 32.

[0028] Understandably, when the bracket cover 34 is fastened, the hook 341 and the locking block 321 engage with each other, thereby enabling the bracket cover 34 to be quickly installed and fixed, improving the product's aesthetics and protecting the internal structure.

[0029] As a preferred option, such as Figure 1 and Figure 3 As shown, the first bracket 33 is provided with an installation groove 332 for inserting one end of the connecting rod 2 and a limiting hole 331 connected to the installation groove 332. The end side of the connecting rod 2 is provided with an installation hole, and a limiting post 21 is slidably connected in the installation hole. A spring is installed between the limiting post 21 and the installation hole to push the limiting post 21 into the limiting hole 331.

[0030] Understandably, when assembling the connecting rod 2, the limiting post 21 is pressed down so that it is completely submerged in the mounting hole. Then, the end of the connecting rod 2 is inserted into the mounting groove 332 of the first bracket 33. When the limiting post 21 is aligned with the limiting hole 331, the spring will push the limiting post 21 into the limiting hole 331, thereby achieving quick connection and locking between the first bracket 33 and the connecting rod 2. When disassembly is required, the connecting rod 2 can be pulled out simply by pressing the limiting post 21 again. This quick-release structure greatly improves the portability and practicality of the product, making it convenient for transportation, packaging, and replacement.

[0031] As a preferred option, such as Figure 1 and Figure 2 As shown, an inner plug sleeve 41 is fixedly connected to one end of the connecting rod 2 near the handle 4, the handle 4 is threaded onto the inner plug sleeve 41, and several anti-slip grooves are provided on the outer side of the handle 4.

[0032] Understandably, using the inner sleeve 41 and the handle 4 threaded connection not only facilitates assembly but also increases the connection's firmness, while the anti-slip groove enhances grip comfort and anti-slip effect.

[0033] As a preferred option, such as Figure 2 As shown, the handle 4 is fixedly connected to the fixing block 42 by fixing screws. The handle 4 is provided with a positioning groove 44. The fixing block 42 is provided with a positioning post 421 for locking into the positioning groove 44. The side of the fixing block 42 away from the handle 4 is hemispherical.

[0034] Understandably, the cooperation between the positioning pin 421 and the positioning groove 44 can improve the assembly accuracy of the fixing block 42 during installation.

[0035] As a preferred option, such as Figure 2 As shown, a silicone sleeve 43 is installed on the outside of the fixing block 42, and a gap groove is formed between the fixing block 42 and the handle 4. The silicone sleeve 43 has an integrally formed edge 431 for engaging in the gap groove.

[0036] Understandably, using a silicone sleeve 43 can further improve the feel and prevent slippage during use.
