[0020] The above main component symbols are combined with the accompanying drawings and specific implementation methods to further illustrate the present invention in detail. DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1 As shown, the embodiment of the utility model provides a brush, which includes: a vibration pump and a brush body structure. The vibration pump includes a connecting rod, which is connected to the brush body structure to provide power for the brush body structure.

[0023] The brush body structure includes: a brush body 1, which includes: a support rod 11 and a brush strip 12. The brush strip 12 is a spiral structure, and the brush strip 12 surrounds the outer peripheral side of the support rod 11. The two ends of the brush strip 12 are respectively connected to the two sides of the support rod 11.

[0024] Among them, the support rod 11 mainly plays the role of support and installation, and the brush strip 12 mainly plays the role of cleaning. The brush strip 12 is designed as a spiral structure. Compared with the existing bristle structure, since the brush strip 12 is an integral structure, the brush strip 12 has better rigidity and strength, and can better clean the inner wall of the barrel. In addition, since the brush strip 12 has good rigidity, it is not easy to deform or be damaged during the cleaning process.

[0025] In addition, the pitch of the brush strip 12 is a, a>0. That is to say, the brush strip 12 is in a relaxed state, and there is a gap between adjacent spiral turns. Due to the friction between the brush strip 12 and the inner wall of the barrel, the brush strip 12 will undergo a certain deformation during the reciprocating movement inside the barrel, and the gap is a space reserved for the deformation of the brush strip 12, reducing damage to the brush strip 12. In addition, the gap also facilitates the removal of dust after wiping.

[0026] In addition, the outer diameter of the brush strip 12 is larger than the inner diameter of the gun barrel. That is to say, when the brush strip 12 extends into the inner wall of the gun barrel, the brush strip 12 can fully contact the inner wall of the gun barrel, thereby better cleaning the inner wall of the gun barrel.

[0027] In addition, the support rod 11 includes: a main body 111, a first step portion 112 and a second step portion 113, the first step portion 112 and the second step portion 113 are respectively connected to both sides of the main body 111, and the diameters of the first step portion 112 and the second step portion 113 are both smaller than the diameter of the main body 111. The first step portion 112 is sleeved with a first support ring 2, and the first support ring 2 is used to support the first step portion 112. The second step portion 113 is sleeved with a second support ring 3, and the first support ring 2 is used to support the second step portion 113.

[0028] It should be noted that the two ends of the brush strip 12 are respectively fixedly connected to the two ends of the main body 111. The first support ring 2 and the second support ring 3 can both play a supporting role. During the cleaning process, the support rod 11 can be prevented from contacting the inner wall of the barrel, thereby protecting the support tube and the inner wall of the barrel.

[0029] In addition, the diameter size of the first support ring 2 and the second support ring 3 can be the same as the diameter size of the inner wall of the barrel, so that the axis of the support rod 11 can be colinear with the axis of the inner wall of the barrel, thereby reducing the radial displacement of the support rod 11 on the inner wall of the barrel during movement, thereby making the movement of the support rod 11 more stable.

[0030] As an optional embodiment, the diameter of the first support ring 2 and the second support ring 3 may also be slightly smaller than the diameter of the inner wall of the barrel, so that the axis of the support rod 11 is approximately collinear with the axis of the inner wall of the barrel.

[0031] Furthermore, the materials of the first support ring 2 and the second support ring 3 are both rubber. Due to the deformable characteristics of the rubber material, it is convenient to insert the first support ring 2 and the second support ring 3 into the barrel. In addition, during the movement of the first support ring 2 and the second support ring 3, the noise generated by the friction between the rubber material and the inner wall of the barrel is small.

[0032] In addition, the first step portion 112 is sleeved with a first gasket 4, and the first gasket 4 is located between the first support ring 2 and the first step portion 112. The second step portion 113 is sleeved with a second gasket 5, and the second gasket 5 is located between the second support ring 3 and the second step portion 113.

[0033] Among them, the first gasket 4 and the second gasket 5 mainly play the role of sealing and pressing. The first gasket 4 is set between the first support ring 2 and the first step portion 112, so that the connection between the first support ring 2 and the first step portion 112 can be tighter, thereby making the setting of the first support ring 2 more reliable and stable.

[0034] Similarly, the second gasket ring 5 is set between the second support ring 3 and the second step portion 113, so that the connection between the second support ring 3 and the second step portion 113 can be tighter, thereby making the setting of the second support ring 3 more secure and stable.

[0035] In addition, a first mounting groove 21 is provided on a side of the first support ring 2 away from the main body 111, a first fastener 6 is provided in the first mounting groove 21, a first connecting portion 7 is provided on a side of the first step portion 112 away from the main body 111, and the first fastener 6 is connected to the first connecting portion 7. A second mounting groove 31 is provided on a side of the second support ring 3 away from the main body 111, a second fastener 8 is provided in the second mounting groove 31, a second connecting portion 9 is provided on a side of the second step portion 113 away from the main body 111, and the second fastener 8 is connected to the second connecting portion 9.

[0036] The first installation groove 21 and the second installation groove 31 can both provide installation space. The first fastener 6 is arranged inside the first installation groove 21, and the first fastener 6 is connected to the first connecting portion 7, so that the first fastener 6 can be used to limit the first support ring 2 in the axial direction of the support rod 11, further improving the stability of the first support ring 2 on the first step portion 112. Moreover, the first fastener 6 can be prevented from contacting and colliding with the inner wall of the barrel.

[0037] Similarly, the second fastener 8 is disposed inside the second mounting groove 31, and the second fastener 8 is connected to the second connecting portion 9, so that the second fastener 8 can be used to limit the second support ring 3 in the axial direction of the support rod 11, further improving the stability of the second support ring 3 on the second step portion 113. Moreover, the second fastener 8 can be prevented from contacting and colliding with the inner wall of the barrel.

[0038] Furthermore, the first connection part 7 and the second connection part 9 can both be internal threads, the first fastener 6 is a self-locking nut, and the second fastener 8 is an extended nut. By using the self-locking nut to thread the first fastener 6 with the first connection part 7, the loosening between the first fastener 6 and the first connection part 7 can be reduced, and the installation is more convenient.

[0039] It should be noted that after the lengthened nut is connected to the second connecting portion 9, it is bonded with a fastening glue to make the connection between the lengthened nut and the second connecting portion 9 more stable. In addition, the connection on the vibration pump is connected to the second step portion 113 on the support rod 11 by cooperating with the lengthened nut.

[0040] In addition, the brush body structure further includes: a first protection pad 10, a second protection pad 20, a third protection pad 30 and a fourth protection pad 40. The first protection pad 10 to the fourth protection pad 40 can all play a protective role.

[0041] Specifically, the first protective pad 10 and the second protective pad 20 are both sleeved on the first step, the first protective pad 10 is located between the first support ring 2 and the main body 111, and the second protective pad 20 is located between the first fastener 6 and the bottom of the first mounting groove 21. The first protective pad 10 is arranged between the first support ring 2 and the main body 111, so that the first support ring 2 can be separated from the main body 111, and the squeezing force of the main body 111 on the first support ring 2 can be reduced, thereby protecting the first support ring 2. The second protective pad 20 is arranged between the first fastener 6 and the bottom of the first mounting groove 21, so that the first support ring 2 can be separated from the first fastener 6, and the squeezing force of the first fastener 6 on the first support ring 2 can be reduced, thereby further protecting the first support ring 2.

[0042] Similarly, the third protection pad 30 and the fourth protection pad 40 are both sleeved on the second step, the third protection pad 30 is located between the second support ring 3 and the main body 111 , and the fourth protection pad 40 is located between the second fastener 8 and the bottom of the second installation groove 31 .

[0043] The third protective pad 30 is arranged between the second support ring 3 and the main body 111, so that the second support ring 3 can be separated from the main body 111, the squeezing force of the main body 111 on the second support ring 3 can be reduced, and the second support ring 3 can be protected. The fourth protective pad 40 is arranged between the second fastener 8 and the bottom of the second mounting groove 31, so that the second support ring 3 can be separated from the second fastener 8, the squeezing force of the second fastener 8 on the second support ring 3 can be reduced, and the second support ring 3 can be further protected.
