The outer wall of the connecting rod is fitted with a shell, a protective shell at the left end of the shell, a precision brush device inside the protective shell, and a regular brush at the right end of the protective shell. For cylindrical cultural relics, a regular brush, a coarse brush, and a fine brush are assembled on a single device. The brushes can be freely changed according to the different structures of the cultural relic, saving time, accelerating the restoration process, and ensuring a more thorough cleaning and preservation of the relic.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following defects in this patent:

[0005] Although the patent includes a device that assembles ordinary brushes, coarse brushes, and fine brushes, the switching process is rather cumbersome and not convenient for operators to quickly select and switch between them. In addition, the dust raised by the brushes during the cleaning of cultural relics can cause health problems for the operators and also cause secondary pollution to the cultural relics.

[0006] Therefore, in response to the above problems, the applicant provides a cleaning brush for cultural relic restoration. Utility Model Content

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] This application discloses a cleaning brush for cultural relic restoration.

[0027] like Figure 1-5 As shown, a cleaning brush for cultural relic restoration includes a receiving box 1 and a handle 4. The receiving box 1 is provided with a pressing mechanism, which includes a limiting piece 2 and a fixing rod 31. A spring 32 is sleeved on the fixing rod 31, and a locking block 30 is fixedly connected to one end of the fixing rod 31. The locking block 30 is engaged in the locking groove 20.

[0028] The handle 4 is equipped with a dust collection mechanism, which includes a connecting pipe 5. The two ends of the connecting pipe 5 are respectively fixedly connected to a dust collection hood 50 and a dust collection box 8. The air inlet of the miniature suction fan 10 passes through one side of the dust collection box 8.

[0029] Please see Figure 1 and Figure 2 Four fixing rods 31 are inserted into the top of the container 1. Buttons 33 and locking blocks 30 are fixedly connected to both ends of the four fixing rods 31. Springs 32 are sleeved on the four fixing rods 31 and are located on the top of the buttons 33 and the container 1. The locking blocks 30, fixing rods 31, springs 32 and buttons 33 are combined to form a pressing component 3. Anti-slip textures are provided on two corresponding sides of the container 1 to facilitate the operator's grip.

[0030] Please see Figure 1 and Figure 2 The receiving box 1 has a limit rod 1 22 and a limit rod 24 passing through its two sides. A spring 1 23 is sleeved on the limit rod 1 22. One end of the spring 1 23 contacts the inner side of the receiving box 1. The ends of the limit rod 1 22 and the limit rod 24 that are close to each other are fixedly connected to the limit piece 2. The limit piece 2 has a release groove 21 and three locking grooves 20.

[0031] Please see Figure 1 and Figure 2 The bottom of the receiving box 1 has a sliding groove, and the bottom surface of the limiting piece 2 is fixedly connected to a slider 25. The slider 25 is slidably connected to the sliding groove. The bottom of each of the three locking blocks 30 is fixedly connected to a handle 4. The slider 25 and the sliding groove are designed to facilitate smoother linear movement of the limiting piece 2. When the operator presses one of the buttons 33 with a handle 4, the button 33 will press down and cause the second spring 32 to compress, and the locking block 30 will engage in the corresponding locking groove 20. At this time, the limiting piece 2 will move laterally to the left during the engagement of the locking block 30. At this time, the first spring 23 is compressed, and the position of the handle 4 after being pressed down is lower than the other two handles. 4. When it is necessary to switch the other two handles 4, simply press the button 33 connected to the handle 4. Pressing down the button 33 will cause the limiting piece 2 to move to the left. At this time, the initially pressed block 30 will disengage from the locking groove 20, and the spring 2 32 will rebound to reset the button 33 upward. At this time, the newly pressed block 30 will re-engage into the locking groove 20. One of the blocks 30 without a handle 4 is a release button. When the button 33 is pressed, the block 30 will fall into the release groove 21. At this time, the limiting piece 2 moves to the left, causing the block 30 in the locking groove 20 to leave and reset upward under the rebound of the spring 2 32.

[0032] Please see Figure 3 Each of the three handles 4 has a placement cavity 40, in which a connecting tube 5 is placed. A connecting rod 6 is fixedly connected to the bottom inner wall of the dust collection hood 50, and a brush 7 is fixedly connected to the connecting rod 6. The three brushes 7 are a precision brush, a coarse brush, and a fine brush, respectively. The precision brush, coarse brush, and fine brush can be easily switched by the operator to use the required brush. At the same time, the operation of the pressing mechanism ensures that the three brushes do not interfere with each other, thus facilitating flexible use by the operator. A conical air intake cavity is formed between the dust collection hood 50 and the outer periphery of the brushes 7, and the dust collection hood 50 is a transparent structure, which makes it easy for the operator to observe the cleaning situation using the brushes 7.

[0033] Please see Figure 5A sealing cover 80 is snapped onto the dust collection box 8, and a dust filter 9 is inserted into the sealing cover 80. The dust filter 9 is located between the sealing cover 80 and the dust collection box 8. A bracket is fixedly connected to the bottom of the miniature suction fan 10, which is fixedly connected to one side of the dust collection box 8. The bottom of the dust collection box 8 has a built-in power supply module. The bottom of the three handles 4 is equipped with an opening and closing switch for the dust collection box 8. The miniature suction fan 10 is started by opening and closing the switch. The miniature suction fan 10 will suck in the air from the dust collection hood 50 and enter the dust collection box 8 through the connecting pipe 5. The dust filter 9 intercepts the dust particles, and then the miniature suction fan 10 will discharge the intercepted air. A sealing ring is set between the sealing cover 80 and the dust collection box 8. On the one hand, it is convenient to remove the sealing cover 80 from the dust collection box 8 and remove the dust filter 9 for cleaning. On the other hand, it avoids air leakage caused by the sealing cover 80 and the dust collection box 8 not sealing tightly when the miniature suction fan 10 is working.

[0034] The implementation principle of a cleaning brush for cultural relic restoration in this application embodiment is as follows:

[0035] The operator presses one of the buttons 33 with handle 4. Button 33 presses down, causing spring 2 32 to compress and locking block 30 to engage in the corresponding locking groove 20. At this time, the limiting piece 2 will move laterally to the left during the engagement of locking block 30. Spring 1 23 is compressed, and the position of handle 4 after pressing down is lower than the other two handles 4. When it is necessary to switch the other two handles 4, simply press the button 33 connected to handle 4. Pressing down button 33 will cause limiting piece 2 to move laterally to the left. At this time, the initially pressed locking block 30 will disengage from the locking groove 20, and spring 2 32 will rebound, causing button 33 to return to its original position. The newly pressed locking block 30 will then re-engage in the locking groove 20. Through the above operation, the brushes 7 on the three handles 4 will be lowered to a position convenient for the operator to use as button 33 is pressed. This makes switching between precision brush, coarse brush and fine brush more convenient and quick, and can be completed by simply pressing button 33, making it easier for the operator to switch and making the operation more flexible.

[0036] The miniature suction fan 10 draws air from the dust collection hood 50 and into the dust collection box 8 through the connecting pipe 5. The dust filter 9 intercepts dust particles, and then the miniature suction fan 10 discharges the intercepted air, thereby effectively collecting the dust and dirt generated by the brush 7 during the cleaning process, preventing it from spreading to the surrounding environment, thus protecting the health of the operators. At the same time, it also reduces secondary pollution of cultural relics by dust and improves the cleaning effect.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
