[0022] 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.

[0023] like Figure 1 and Figure 2 As shown, an embodiment of the utility model proposes a brush, which includes: bristles 4, a vibration pump and a combined brush body. The vibration pump includes a connecting rod. The material of the bristles 4 can be a composite material with high structural strength or a stainless steel material, which is not easy to be damaged and durable. The combined brush body includes: a first brush body 1 and a second brush body 2. In other words, the brush body structure is composed of two main parts, the first brush body 1 and the second brush body 2, and the first brush body 1 and the second brush body 2 are fixedly connected, so that the connection between the first brush body 1 and the second brush body 2 can be more stable, and the brush can work better. The material of the first brush body 1 and the second brush body 2 can be nylon material.

[0024] The first brush body 1 and the second brush body 2 both play the main role of installation and support. A first through hole 11 is provided inside the first brush body 1, and a second through hole 21 is provided inside the second brush body 2. The first through hole 11 and the second through hole 21 are arranged opposite to each other, that is, the first through hole 11 and the second through hole 21 are connected to each other, so that the connecting rod on the vibration pump can pass through the first through hole 11 and the second through hole 21 at the same time to connect with the first brush body 1 and the second brush body 2.

[0025] In addition, the bristles 4 can pass through the first through hole 11 and the second through hole 21 to the outside of the first brush body 1 and the second brush body 2 to facilitate cleaning of the inner wall of the barrel. During installation, the bristles 4 can be installed on the first brush body 1 and the second brush body 2 respectively, and then the first brush body 1 and the second brush body 2 with the bristles 4 installed are connected.

[0026] Therefore, compared with the existing integral structure, the combined brush body structure composed of the first brush body 1 and the second brush body 2 can install the bristles 4 on the first brush body 1 and the second brush body 2 separately, and then connect the first brush body 1 and the second brush body 2 after the installation of the bristles 4 is completed. Since the first brush body 1 and the second brush body 2 are shorter and have a relatively larger internal space than the integral structure, it is easier to thread the bristles 4, thereby facilitating the installation of the bristles 4.

[0027] In addition, the cross-sectional shapes of the first brush body 1 and the second brush body 2 are both circular. Since the cross-sectional shape of the inner wall of the gun barrel is circular, the cross-sectional shapes of the first brush body 1 and the second brush body 2 are set to be circular, so that the first brush body 1 and the second brush body 2 can be more adapted to the inner wall shape of the gun barrel, thereby making the design more reasonable. After the bristles 4 are installed on the first brush body 1 and the second brush body 2, it is easier to clean the inner wall of the gun barrel.

[0028] It should be noted that since the first brush body 1 and the second brush body 2 are cylindrical structures, the bristles 4 installed on the first brush body 1 and the second brush body 2 are approximately annular in shape when viewed in the axial direction. The diameter of this annular structure is larger than the diameter of the inner wall of the barrel, so that the bristles 4 can fully contact the inner wall of the barrel, thereby facilitating the cleaning of the inner wall of the barrel.

[0029] The first brush body 1 is provided with a first connecting portion 12 at one end close to the second brush body 2, and the second brush body 2 is provided with a second connecting portion 22 at one end close to the first brush body 1, and the second connecting portion 22 is connected to the first connecting portion 12. Through the connection between the first connecting portion 12 and the second connecting portion 22, the connection between the first brush body 1 and the second brush body 2 can be made more stable, so that the structure of the combined brush body can be made more stable.

[0030] As an optional embodiment, the first connection portion 12 is an internal thread, and the second connection portion 22 is an external thread. The connection between the internal thread and the external thread is more convenient and easy to install.

[0031] As an optional embodiment, the first connection portion 12 is a slot, and the second connection portion 22 is a buckle. Both the buckle and the slot are common technologies in the prior art, and have simple structures and are easy to process.

[0032] It should be noted that after the first connection part 12 is connected to the second connection part 22 , a fastening adhesive is used for bonding, so that the connection between the first brush body 1 and the second brush body 2 is more secure and stable.

[0033] In addition, a plurality of brush holes 3 are provided on the first brush body 1 and the second brush body 2. The brush holes 3 are mainly used for installation, and the bristles 4 are installed in the brush holes 3, so that the bristles 4 can be supported and installed. Specifically, a plurality of bristles 4 are provided, and the plurality of bristles 4 pass through the corresponding brush holes 3 to the outside of the first brush body 1 and the second brush body 2.

[0034] In addition, all the brush holes 3 on the first brush body 1 form a plurality of brush hole arrays, which are spaced apart in the axial direction of the first brush body 1 , each brush hole array includes a plurality of brush holes 3 , and the plurality of brush holes 3 in each brush hole array are distributed at equal angles along the circumference of the first brush body 1 .

[0035] That is, all the brush holes 3 on the first brush body 1 are evenly spaced on the first brush body 1, so that the contact area between the bristles 4 installed on the first brush body 1 and the inner wall of the barrel can be increased, so that the inner wall of the barrel can be better cleaned. Moreover, the spacing between the multiple brush holes 3 can also reduce the impact on the structural strength of the first brush body 1.

[0036] Similarly, all the brush holes 3 on the second brush body 2 form a plurality of brush hole arrays, which are spaced apart in the axial direction of the second brush body 2 , each brush hole array includes a plurality of brush holes 3 , and the plurality of brush holes 3 in each brush hole array are distributed at equal angles along the circumference of the second brush body 2 .

[0037] That is, all the brush holes 3 on the first brush body 1 are evenly spaced on the first brush body 1, so that the contact area between the bristles 4 installed on the first brush body 1 and the inner wall of the barrel can be increased, so that the inner wall of the barrel can be better cleaned. Moreover, the spacing between the multiple brush holes 3 can also reduce the impact on the structural strength of the first brush body 1.

[0038] Furthermore, the inner wall of the first brush body 1 and the inner wall of the second brush body 2 are both provided with wire grooves 5, and the parts of the bristles 4 located in the first through hole 11 and the second through hole 21 are arranged in the wire grooves 5. The wire grooves 5 mainly play a role of storage. Since the bristles 4 need to be passed through the interior of the first brush body 1 and the second brush body 2 respectively during installation, in order to reduce the interference between the bristles 4 and the interference between the bristles 4 and the upper connecting rod of the vibration pump, the parts of the bristles 4 located in the first brush body 1 and the second brush body 2 are stored in the wire grooves 5. This arrangement is more reasonable and can better avoid interference.

[0039] In addition, the brush further includes: a first connection seat 6 and a second connection seat 7, the first connection seat 6 is arranged in the first through hole 11, and the first connection seat 6 is connected to the inner wall of the first brush body 1, and a third through hole 61 is provided on the first connection seat 6. The second connection seat 7 is arranged in the second through hole 21, and the second connection seat 7 is connected to the inner wall of the second brush body 2, and a fourth through hole 71 is provided on the second connection seat 7, and the connecting rod passes through the third through hole 61 and the fourth through hole 71 and is connected to the first connection seat 6 and the second connection seat 7.

[0040] The first connection seat 6 and the second connection seat 7 both mainly play a connecting role. The first connection seat 6 is arranged in the first through hole 11, and the first connection seat 6 is connected to the inner wall of the first brush body 1, so that the connection between the first connection seat 6 and the inner wall of the first brush body 1 can be more stable. Similarly, the second connection seat 7 is arranged in the second through hole 21, and the second connection seat 7 is connected to the inner wall of the second brush body 2, so that the connection between the second connection seat 7 and the inner wall of the second brush body 2 can be more stable.

[0041] In addition, a third through hole 61 is provided on the first connection seat 6, a fourth through hole 71 is provided on the second connection seat 7, and the connecting rod passes through the third through hole 61 and the fourth through hole 71 to connect with the first connection seat 6 and the second connection seat 7. In other words, the connecting rod is fixedly connected through the third through hole 61 and the fourth through hole 71, so that it can be indirectly connected with the first connection seat 6 and the second connection seat 7, so that the first brush body 1 and the second brush body 2 can be protected, and the first connection seat 6 and the second connection seat 7 can be replaced, which is more convenient to use.

[0042] Furthermore, a first boss 63 is provided on the inner wall of the first brush body 1, and a first groove 62 is provided on the outer wall of the first connecting seat 6, and the first boss 63 is engaged with the first groove 62. Through the engagement between the first boss 63 and the first groove 62, the first connecting seat 6 can be limited, so that the connection between the first connecting seat 6 and the first brush body 1 can be more stable.

[0043] Similarly, a second boss 73 is provided on the inner wall of the second brush body 2, and a second groove 72 is provided on the outer wall of the first connecting seat 6, and the second boss 73 is engaged with the second groove 72. Through the engagement between the second boss 73 and the second groove 72, the second connecting seat 7 can be limited, so that the connection between the second connecting seat 7 and the second brush body 2 can be more stable.

[0044] As an optional embodiment, the first boss 63 and the second boss 73 are annular structures, and the first groove 62 and the second groove 72 are annular structures. The first boss 63 and the first groove 62 are designed as annular structures, which can increase the matching area between the first boss 63 and the first groove 62, so that the connection between the first boss 63 and the first groove 62 can be more stable. Similarly, the second boss 73 and the second groove 72 are designed as annular structures, which can increase the matching area between the second boss 73 and the second groove 72, so that the connection between the second boss 73 and the second groove 72 can be more stable.

[0045] As an optional embodiment, the length of the bristles 4 in the middle of the combined brush body extending out of the first brush body 1 and the second brush body 2 is greater than the length of the bristles 4 on both sides of the combined brush body extending out of the first brush body 1 and the second brush body 2. It should be noted that the inner bore of the gun barrel is divided into a negative line and a positive line, and the diameter of the negative line is greater than the diameter of the positive line. Therefore, the length of the bristles 4 in the middle of the combined brush body extending out of the first brush body 1 and the second brush body 2 is greater than the length of the bristles 4 on both sides of the combined brush body extending out of the first brush body 1 and the second brush body 2. The design is more reasonable, and the bristles 4 in the middle of the combined brush body can be used to better clean the negative line, while the bristles 4 on both sides of the combined brush body can better clean the positive line.

[0046] As an optional embodiment, the density of the bristles 4 in the middle of the combined brush body is less than the density of the bristles 4 on both sides of the combined brush body. Among them, the bristles 4 in the middle of the combined brush body mainly play a guiding role. Since the vibration pump will only reciprocate along the axial direction of the barrel inside the barrel, the movement direction of the vibration pump can be determined according to the direction of the bristles 4 falling forward or backward. For example, when the bristles 4 fall backward, the connecting rod of the vibration pump moves forward. In addition, the density of the bristles 4 in the middle of the combined brush body is less than the density on both sides, which can reduce the friction between the bristles 4 in the middle of the combined brush body and the inner wall of the barrel, reduce the resistance of the brush when moving inside the barrel, and facilitate the movement of the combined brush body inside the barrel.

[0047] It should be noted that the bristles 4 at both ends of the combined brush body can be made of steel wire or composite material, and the bristles 4 in the middle part can be made of composite material. The steel wire has a certain rigidity, which not only ensures the effective removal of copper, plastic and rust, but also is not easy to deform plastically, which is conducive to the bristles 4 to peel off the stains on the inner wall of the gun barrel.

[0048] It should be noted that when a component is referred to as being "mounted on" another component, it may be directly on the other component or there may be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a central component at the same time. When a component is considered to be "fixed to" another component, it may be directly fixed on the other component or there may be a central component at the same time.
