[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0040] The embodiment of the present application provides a precision instrument cleaning tool, which can solve the problem that the existing precision instrument cleaning method is only immersion and blowing, resulting in the inability to completely clean the stubborn dirt inside the atomizer and atomization chamber, low cleaning efficiency, poor cleaning effect, and thus requiring frequent cleaning and maintenance.

[0041] See also Figure 1-6 As shown, the embodiment of the present application is a precision instrument cleaning tool, comprising:

[0042] The cleaning mechanism includes a cleaning brush head assembly that can vibrate for cleaning and adapt to different inner cavities, and a snake-bone rod structure 3 that is used to allow the cleaning brush head assembly to extend into the interior of an instrument for cleaning and can adjust the angle. The snake-bone rod structure 3 can actively adjust different directions to allow the cleaning brush head assembly to adapt to different internal space cavities of the instrument. One end of the snake-bone rod structure 3 is provided with a fixed seat 1 for installing and connecting the cleaning brush head assembly.

[0043] The snake-bone rod structure 3 allows the cleaning brush head assembly to extend into a complex cavity for cleaning, or it needs to enter an internal space through the cavity for cleaning. The snake-bone structure itself can be bent at will, and after the cleaning brush head assembly uses the snake-bone rod structure 3 to extend into the internal space, the individual snake-bone nodes in the snake-bone rod structure 3 can also be controlled to change the angle and orientation of the snake-bone nodes where the cleaning brush head assembly is provided, so that the cleaning brush head assembly can contact the dirt and then vibrate to clean.

[0044] Cleaning the inside of precision instruments by vibration makes residual dirt fall off more easily, thus improving cleaning efficiency and the accuracy of precision instruments when in use, avoiding the presence of dirt inside the instrument that may reduce the accuracy of instrument detection.

[0045] The cleaning brush head assembly can also adapt to different inner cavity structures, so that the cleaning brush head assembly can change its angle, further improving the flexibility of the cleaning mechanism, and avoiding the dead angle of the snake-bone rod structure 3 that makes it impossible for the cleaning brush head assembly to clean. The cleaning brush head assembly can also be suitable for inner cavity structures with different arcs, so that the cleaning brush head assembly can adjust different arcs to adapt to the internal shape of the cavity. For example, if the interior of the atomization chamber is an arc-shaped structure, the cleaning brush head assembly can be adjusted to adapt to the arc-shaped inner wall inside the atomization chamber, so that the cleaning range is increased and the cleaning angle is further improved.

[0046] In some optional embodiments, see Figure 1-3 As shown, in the precision instrument cleaning tool, the cleaning brush head assembly includes a brush head 27, a first adjustment mechanism that rotates around the X-axis to adjust the angle of the brush head 27, and a second adjustment mechanism that is arranged on the fixed base 1 and enables the first adjustment mechanism to rotate around the Y-axis.

[0047] In this embodiment, the second adjustment mechanism includes two oppositely arranged first support plates 9 and second support plates 15 on the fixed base 1, and a first rotating rod 28 rotatably connected between the first support plates 9 and the second support plates 15. The first rotating rod 28 is provided with a first connecting rod 8 connected to the first adjustment mechanism.

[0048] In this embodiment, a motor compartment is opened inside the second supporting plate 15 , and a first motor 14 is arranged in the motor compartment of the second supporting plate 15 . The output shaft of the first motor 14 is drivingly connected to the first rotating rod 28 .

[0049] The first adjustment mechanism and the second adjustment mechanism have the same structure and principle, except that the adjustment directions and angles of the first adjustment mechanism and the second adjustment mechanism are different. For example, the adjustment direction of the first adjustment mechanism is rotation around the X-axis direction or the front and back sides, and the adjustment direction of the second adjustment mechanism is rotation around the Y-axis direction or the left and right sides. Of course, when the snake-bone rod structure 3 moves, the first adjustment mechanism will also be adjusted to rotate around the Y-axis direction or the left and right sides, and the second adjustment mechanism will be adjusted to rotate around the X-axis direction or the front and back sides, as long as the first adjustment mechanism and the second adjustment mechanism are in two different directions.

[0050] The first adjustment mechanism includes a first motor 14, a first support plate 9, a second support plate 15, a first rotating rod 28 and a first connecting rod 8, and also includes a base 13 arranged at an end of the first connecting rod 8 away from the first rotating rod 28, and a brush head 27 is detachably connected to the base 13.

[0051] When the cleaning brush head assembly enters the interior of the instrument for cleaning, the first motor 14 drives the first rotating rod 28 to rotate, so that the first rotating rod 28 can drive the first connecting rod 8 to rotate, and the first connecting rod 8 can drive the first adjusting assembly to rotate and adjust the direction. For example, the second adjusting mechanism is used to make the first adjusting mechanism rotate left and right, and then the first motor 14 in the first adjusting mechanism drives the first rotating rod 28 to rotate, so that the brush head 27 connected to the first rotating rod 28 rotates back and forth, and the brush head 27 can achieve multi-directional adjustment angles by using the first adjustment mechanism and the second adjustment mechanism to adjust the angle in multiple directions, thereby avoiding the inconvenience of adjusting the angle after the snake-bone rod structure 3 is extended, or when the angle is limited, the dirt cannot be cleaned, the cleaning angle range of the brush head 27 is increased, and the flexibility of the cleaning mechanism is improved.

[0052] The cleaning brush head assembly in this embodiment is not limited to the snake-bone rod structure 3, and can also be used on other rods that are elastic and can change angles.

[0053] In some optional embodiments, see Figure 1 and Figure 5-6 As shown, in the precision instrument cleaning tool, the cleaning brush head assembly includes a connecting rod 20 detachably connected to the fixed seat 1 and a brush head holder mechanism 22 which is arranged on the outside of the connecting rod 20 and can be expanded and retracted. The connecting rod 20 is a hollow structure, and a plurality of long holes 21 arranged in a ring around the center of the rod are opened on the outer wall of the connecting rod 20. The long holes 21 are connected to the interior of the connecting rod 20, and a driving mechanism for expanding and retracting the brush head holder mechanism 22 is arranged inside the connecting rod 20.

[0054] In this embodiment, the driving mechanism includes a second motor 26 arranged on the inner side of the bottom of the connecting rod 20 and a lifting block 18 arranged above the second motor 26. The lifting block 18 is provided with a first threaded hole 25 on the side facing the second motor 26. A threaded rod 17 is connected to the first threaded hole 25 of the lifting block 18. The end of the threaded rod 17 away from the lifting block 18 is transmission-connected to the second motor 26. The lifting block 18 is connected to the brush head holder mechanism 22.

[0055] In this embodiment, the brush head rack mechanism 22 includes a plurality of support rod structures 19 arranged in a ring around the center of the connecting rod 20, a top rod 29 arranged at the end of the connecting rod 20 away from the fixed seat 1, and bristles 23 arranged on the side wall of the support rod structure 19. One end of the support rod structure 19 is hinged to the lifting block 18 through the long hole 21, and the other end of the support rod structure 19 is hinged to the top rod 29. The support rod structure 19 is composed of a plurality of arc-shaped short rods hinged to each other.

[0056] The support rod structure 19 in this embodiment can be unfolded into an arc shape, so that it can fit the inner wall of the internal cavity of the instrument at more angles, so that it can clean multiple dirts and multiple angles over a large area, avoiding the brush head 27 cleaning in only one direction and only one dirt at a time.

[0057] When it is necessary to use a cleaning brush head assembly with a support rod structure 19, an external thread is provided on the outer wall of one end of the connecting rod 20 connected to the fixing seat 1, which can be threadedly connected to the second threaded hole on the fixing seat 1. When the cleaning brush head assembly is extended into the instrument through the snake-bone rod structure 3, the second motor 26 drives the threaded rod 17 to rotate, and the threaded rod 17 rotates to make the lifting block 18 rise and fall to adjust the height. The support rod structure 19 is composed of a plurality of arc-shaped short rods hinged to each other, and one end of the support rod structure 19 is hinged to the lifting block 18, and the other end is hinged to the top rod 29. When the lifting block 18 is raised, the distance between the top rod 29 and the lifting block 18 becomes shorter, so that the support rod structure 19 is squeezed, and the support rod structure 19 will expand toward the outside, so that the support rod structure 19 expands into an arc shape to adapt to the distance between the top rod 29 and the lifting block 18, and the short rods are all arc-shaped. When the support rod structure 19 is unfolded, the support rod structure 19 can be spherically unfolded through the arc-shaped short rods.

[0058] Because there are several support rod structures 19 and they are arranged in a ring around the center of the connecting rod 20, the brush head frame mechanism 22 will have a spherical skeleton, which can enable the cleaning brush head assembly to clean dirt at multiple angles and multiple dirt at one time, thereby increasing the cleaning area and improving the cleaning efficiency.

[0059] When cleaning is completed, the lifting block 18 descends to drive the support rod structure 19 to shrink and recover, thereby reducing the volume of the space so that the support rod structure 19 can pass through the narrow cavity again.

[0060] In some optional embodiments, see Figure 1 As shown, in the precision instrument cleaning tool, the brush head 27 includes a fixed rod and fiber bristles.

[0061] In some optional embodiments, see Figure 1 As shown, in the precision instrument cleaning tool, a second threaded hole is formed on the fixing seat 1 , and the fixing rod is threadedly connected to the second threaded hole of the fixing seat 1 .

[0062] In some optional embodiments, see Figure 1 As shown, in the precision instrument cleaning tool, a vibration motor for vibrating the cleaning brush head assembly is arranged in the fixing seat 1, and a control rod 5 for controlling the adjustment direction and a switch 4 for controlling the vibration of the vibration motor are arranged at one end of the snake-bone rod structure 3 away from the cleaning brush head assembly.

[0063] Working principle and process of this application:

[0064] The snake-bone rod structure 3 can be used to extend the cleaning brush head assembly into a complex cavity for cleaning, or when it needs to enter an internal space through a cavity for cleaning, the snake-bone structure itself can be bent at will, and after the cleaning brush head assembly extends into the internal space using the snake-bone rod structure 3, the individual snake-bone nodes in the snake-bone rod structure 3 can also be controlled, and the angle orientation of the cleaning brush head assembly can be changed through the snake-bone rod structure 3, so that the cleaning brush head assembly can contact the dirt and then vibrate to clean.
