Description

Technical Field

[0001] This utility model relates to the field of pipe brush technology, and in particular to a pipe brush for cleaning slender pipes. Background Technology

[0002] Slender pipes are widely used in many fields. In industrial production, they are used for transporting various chemical fluids and gases; in the medical field, they are used in the slender channels of some medical devices; and in daily life, they are used in ventilation ducts and water pipes for air conditioning. During use, due to fluid flow, the adhesion of substances, and the accumulation of dust, dirt and impurities gradually accumulate on the inner walls of these slender pipes, requiring regular cleaning to ensure normal operation and safe use. However, it is difficult to reach the interior of slender pipes, or one can only reach a shallow part of the pipe, making it impossible to thoroughly clean the inside. For example, gun barrels are a typical example of slender pipes, and ordinary cleaning brushes cannot effectively reach their interiors for cleaning, thus affecting the performance and lifespan of the gun. Similarly, after long-term use, sewage pipes accumulate a large amount of dirt and debris on their inner walls, and traditional cleaning brushes cannot reach the depths of the pipes for thorough cleaning, leading to blockages and contamination problems. To solve the cleaning challenges of slender pipes, specialized pipe brushes have been developed. These pipe brushes typically have special designs and structures to adapt to the shape and cleaning requirements of slender pipes.

[0003] Chinese patent application CN202221789340.3 discloses a pipe brush for cleaning long and narrow pipes. The key technical points of the invention are: the invention is equipped with an adjusting rod, an adjusting groove, and an adjusting assembly. When the length of the entire pipe brush needs to be adjusted, two sets of pull plates are pulled. The force on the two sets of pull plates drives two sets of fixed blocks to move in a direction away from the fixed groove and closer to the groove through two sets of pull rods. When the two sets of fixed blocks are completely disengaged from the fixed groove, the adjusting rod is pulled to slide in the adjusting groove. When the adjusting rod slides to the appropriate position, the two sets of pull plates are released. By utilizing the restoring property of the spring, the two sets of fixed blocks are driven to re-insert into the fixed groove.

[0004] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: when cleaning deeper and narrow pipes, the brush cannot reach the cleaning position; when the pipe is long and the hollow pipe is not replaced, it is difficult to clean some distant or deep areas; when cleaning the drain of the kitchen sink or the corner of the bathtub, the brush is not long enough to reach these areas, thus failing to effectively remove dirt and dust; therefore, in order to address the above problems, a pipe brush for cleaning narrow pipes is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability of brushes to reach the cleaning positions when cleaning deeper, narrow pipes, the difficulty in cleaning distant or deep areas when the pipes are long and the hollow pipe is not replaced, and the inability to effectively remove dirt and dust when cleaning kitchen sink drains or bathtub corners due to insufficient brush length. Therefore, this invention proposes a pipe brush for cleaning narrow pipes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pipe brush for cleaning slender pipes, comprising a brush, wherein the arc surface of the brush is provided with a replacement device, the replacement device comprising a hollow tube, the hollow tube being slidably connected to the arc surface of the brush, the inner surface of the hollow tube having two blocking holes, the arc surface of the hollow tube having two threaded holes, the arc surface of the brush having two mounting grooves, the inner surface of the mounting groove being fixedly connected to a first spring, the other end of the first spring being fixedly connected to a blocking block, and the inner surface of the hollow tube being fixedly connected to a fixing block.

[0007] The effect achieved by the above-mentioned components is as follows: by setting up the replacement device, the hollow tube can be replaced, avoiding the situation where the brush cannot reach the cleaning position when cleaning deeper and thinner pipes. When the pipe is long and the hollow tube is not replaced, it is difficult to clean some distant or deep areas. When cleaning the drain of the kitchen sink or the corner of the bathtub, the brush is not long enough to reach these areas, thus failing to effectively remove dirt and dust.

[0008] Preferably, a second spring is fixedly connected to one side of the fixing block, and a pressing block is fixedly connected to the other end of the second spring.

[0009] The effect achieved by the above components is that when the hollow tube needs to be replaced, the second spring pushes the pressing block, which in turn pushes the brush to move, thus speeding up the time for disassembling the brush.

[0010] Preferably, a threaded rod is threaded into the inner surface of the threaded hole, and a round block is fixedly connected to one end of the threaded rod.

[0011] The effect achieved by the above-mentioned components is as follows: by setting the threaded rod, the blocking block is pushed to slide to the inner surface of the placement groove, thereby releasing the blocking block from obstructing the hollow tube.

[0012] Preferably, a positioning plate is fixedly connected to the arc surface of the threaded rod, and one side of the positioning plate abuts against the hollow tube.

[0013] The effect achieved by the above components is that when the threaded rod is rotated, and one side of the positioning plate abuts against the hollow tube, the top of the blocking block is flush with the arc surface of the brush, making it easier for the user to disassemble the hollow tube.

[0014] Preferably, one end of the hollow tube is provided with a cleaning device, the cleaning device including a round tube, the round tube being fixedly connected to one end of the hollow tube, a cleaning ring being slidably connected to the arc surface of the round tube, a sliding block being fixedly connected to the inner surface of the cleaning ring, a locking block being fixedly connected to one end of the round tube, and a placement ring being fixedly connected to one side of the locking block.

[0015] The effects achieved by the above components are as follows: by setting up the cleaning device, the surface of the round tube is cleaned, and the user can easily control the round tube. Slipping of the hand will make the brush less maneuverable, making it difficult to accurately control the direction and force of the brush movement. During the cleaning process, some areas may be missed or the wiping force of the stains may be uneven, resulting in the stains not being completely removed and affecting the cleaning effect.

[0016] Preferably, the arc surface of the cleaning ring has a limiting hole, and a rod is slidably inserted into the limiting hole of the arc surface of the cleaning ring.

[0017] The effect achieved by the above components is that the insert rod limits the cleaning ring, preventing the cleaning ring from sliding on the arc surface of the round tube during the use of the brush.

[0018] Preferably, two cleaning sponges are fixedly connected to the inner surface of the cleaning ring, and the sliding block is slidably connected to the inner surface of the round tube.

[0019] The effect achieved by the above components is that when there is water stain on the arc surface of the tube, the cleaning cotton enhances the absorption of water stains, thus drying the arc surface of the tube.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] 1. In this utility model, by setting a replacement device, the hollow tube can be replaced, avoiding the situation where the brush cannot reach the cleaning position when cleaning deeper and thinner pipes. When the pipe is long and the hollow tube is not replaced, it is difficult to clean some distant or deep areas. When cleaning the drain of the kitchen sink or the corner of the bathtub, the brush is not long enough to reach these areas, thus failing to effectively remove dirt and dust.

[0022] 2. In this utility model, by setting up a cleaning device, the surface of the round tube is cleaned, and the user can control the round tube more easily. Slipping of the hand will make the brush less maneuverable, making it difficult to accurately control the direction and force of the brush movement. During the cleaning process, some areas may be missed or the wiping force of the stains may be uneven, resulting in the stains not being completely removed and affecting the cleaning effect.

[0028] Reference Figure 1 As shown, this utility model provides a technical solution: a pipe brush for cleaning slender pipes, including a brush 1. The brush 1 has a replacement device 2 on its arc-shaped surface. By setting the replacement device 2, the hollow tube 201 can be replaced, avoiding the situation where the brush 1 cannot reach the cleaning position when cleaning deeper slender pipes. When the pipe is long and the hollow tube 201 is not replaced, it is difficult to clean some distant or deep areas. When cleaning the drain of the kitchen sink or the corner of the bathtub, the brush 1 is not long enough to reach these areas, thus failing to effectively remove dirt and dust. A cleaning device 3 is provided at one end of the hollow tube 201. By setting the cleaning device 3, the surface of the tube 31 is cleaned, and the tube 31 is easily controlled by the user. Slipping of the hand will reduce the maneuverability of the brush 1, making it difficult to accurately control the direction and force of the brush 1's movement. During the cleaning process, some areas may be missed, or the wiping force on the stains may be uneven, resulting in the stains not being completely removed and affecting the cleaning effect.

[0029] The specific setup and function of the replacement device 2 and the cleaning device 3 will be explained in detail below.

[0030] Reference Figure 2 and Figure 3As shown in this embodiment: the replacement device 2 includes a hollow tube 201, which is slidably connected to the arc surface of the brush 1. Two blocking holes 202 are formed on the inner surface of the hollow tube 201, and two threaded holes 203 are formed on the arc surface of the hollow tube 201. Two mounting grooves 204 are formed on the arc surface of the brush 1. A first spring 205 is fixedly connected to the inner surface of the mounting groove 204, and the other end of the first spring 205 is fixedly connected to a blocking block 206. A fixing block 207 is fixedly connected to the inner surface of the hollow tube 201. A second spring 208 is fixedly connected to one side of the fixing block 207, and a pressing block 209 is fixedly connected to the other end of the second spring 208. When the hollow tube 201 needs to be replaced, the second spring 208 pushes the pressing block 209, thereby pushing the brush 1 to move and speeding up the disassembly time of the brush 1. A threaded rod 210 is threadedly inserted into the inner surface of the threaded hole 203, and a round block 211 is fixedly connected to one end of the threaded rod 210. By setting the threaded rod 210, the blocking block 206 is pushed to slide onto the inner surface of the mounting groove 204, thus releasing the blocking block 206 from obstructing the hollow tube 201. A positioning plate 212 is fixedly connected to the arc surface of the threaded rod 210, with one side of the positioning plate 212 abutting against the hollow tube 201. Rotating the threaded rod 210, when one side of the positioning plate 212 abuts against the hollow tube 201, the top of the blocking block 206 is flush with the arc surface of the brush 1, making it easier for the user to disassemble the hollow tube 201.

[0031] Reference Figure 4 As shown, specifically, the cleaning device 3 includes a circular tube 31, one end of which is fixedly connected to the hollow tube 201. A cleaning ring 32 is slidably connected to the arc surface of the circular tube 31, and a sliding block 33 is fixedly connected to the inner surface of the cleaning ring 32. A locking block 34 is fixedly connected to one end of the circular tube 31, and a placement ring 35 is fixedly connected to one side of the locking block 34. A limiting hole is formed on the arc surface of the cleaning ring 32, and an insert rod 36 is slidably inserted into the limiting hole. The insert rod 36 limits the cleaning ring 32 to prevent it from sliding on the arc surface of the circular tube 31 during the use of the brush 1. Two cleaning sponges 37 are fixedly connected to the inner surface of the cleaning ring 32, and the sliding block 33 is slidably connected to the inner surface of the circular tube 31. When there is water on the arc surface of the circular tube 31, the cleaning sponges 37 enhance the absorption of water, allowing the arc surface of the circular tube 31 to dry.

[0032] Working principle: When the user needs to replace the hollow tube 201 using the replacement device 2, firstly, rotating the circular block 211 drives the threaded rod 210 to rotate on the inner surface of the threaded hole 203. When the threaded rod 210 reaches the inner surface of the blocking hole 202, it presses against the blocking block 206, compressing the first spring 205 to slide on the inner surface of the mounting groove 204. When one side of the positioning plate 212 abuts against the arc surface of the hollow tube 201, the top of the blocking block 206 is flush with the arc surface of the brush 1, thus disassembling the hollow tube 201. Due to the support of the fixing block 207, the second spring 208 slides on the inner surface of the hollow tube 201, pushing the pressing block 209 to move, thereby popping the brush 1 into the inner surface of the hollow tube 201. When the operator needs to replace another... When a hollow tube 201 is installed, the rotating block 211 drives the threaded rod 210 to rotate on the inner surface of the threaded hole 203. When one side of the positioning plate 212 moves away from the arc surface of the hollow tube 201, it pushes the brush 1 to slide on the inner surface of the hollow tube 201. Due to the support of the fixing block 207, the second spring 208 slides on the inner surface of the hollow tube 201. The pressing block 209 moves, thereby pushing the brush 1 into the inner surface of the hollow tube 201, squeezing the blocking block 206, and compressing the first spring 205 to slide on the inner surface of the mounting groove 204. When the blocking block 206 is flush with the blocking hole 202, the first spring 205 rebounds and slides on the inner surface of the mounting groove 204. The blocking block 206 enters the inner surface of the blocking hole 202, and the hollow tube 201 is installed.

[0033] When the user needs to clean the round tube 31 using the cleaning device 3, the insertion rod 36 is slid in the round hole of the cleaning ring 32 until the insertion rod 36 disengages from the inner surface of the cleaning ring 32, allowing the cleaning ring 32 to slide on the surface of the round tube 31. The sliding block 33 slides on the inner surface of the round tube 31 until the cleaning ring 32 reaches the side close to the locking block 34 and the placement ring 35. After the cleaning cotton 37 inside the cleaning ring 32 has finished cleaning the surface of the round tube 31, the cleaning ring 32 is pulled to the side away from the locking block 34 and the placement ring 35. The insertion rod 36 is then slid in the round hole of the cleaning ring 32 until the insertion rod 36 enters the inner surface of the cleaning ring 32, thus limiting the cleaning ring 32.
