Description

Technical Field

[0001] This application relates to the field of peristaltic pump technology, and in particular to a peristaltic pump hose that prevents spillage. Background Technology

[0002] A peristaltic pump is a pump that delivers fluid by squeezing and releasing a flexible hose. Its working principle involves a motor driving a roller to rotate. As the roller moves within the pump tube, it squeezes the hose, creating a vacuum that draws in fluid, and then continues rolling to expel the fluid. This type of pump does not require valves; the fluid only contacts the hose and not the pump body, thus offering advantages such as no contamination, low shear force, and easy cleaning. However, existing peristaltic pump hoses are in constant contact with the rollers and require periodic replacement. Currently, during hose replacement, leakage is a common problem due to the presence of liquid inside the hose. Therefore, a leak-proof peristaltic pump hose is proposed. Utility Model Content

[0003] To address the issue of liquid leakage during peristaltic pump hose replacement due to the presence of liquid inside the hose, this application provides a peristaltic pump hose designed to prevent leakage.

[0004] The peristaltic pump hose provided in this application adopts the following technical solution:

[0005] An overflow-proof peristaltic pump hose includes a tube body. An overflow-proof layer is fixedly sleeved on the surface of the power part of the tube body. The overflow-proof layer and the outer surface of the tube body form an overflow-proof cavity. A pressure detector communicating with the overflow-proof cavity is provided on the outside of the overflow-proof layer. Both ends of the tube body are connected to a connecting pipe through an assembly mechanism. The connecting pipe is a pre-set pipe of the peristaltic pump. Each assembly mechanism includes a first connector and a second connector. The first connector is fixedly and continuously connected to the tube body, and the second connector is fixedly and continuously connected to the connecting pipe. A valve body is provided inside the second connector. The first connector and the second connector are detachably connected. An annular stop is provided at the opening of the first connector. A baffle is connected inside the first connector through a moving mechanism. The diameter of the baffle is larger than the diameter of the annular stop and smaller than the inner diameter of the first connector.

[0006] Preferably, the moving mechanism includes guide rods fixedly installed on both sides of the first connector, the guide rods being parallel to the central axis of the first connector, and sliding sleeves adapted to the guide rods being fixedly connected to both sides of the baffle, the sliding sleeves being sleeved on the surface of the guide rods, and springs being sleeved on the surface of the guide rods, the springs causing the baffle to be tightly pressed against the annular stop block, and a top rod being fixedly connected to the connecting end of the second connector, the top rod causing the baffle to move away from the annular stop block when the second connector is connected to the first connector.

[0007] Preferably, the inner surface of the annular stop is provided with an internal thread, the connecting end of the second connector is adapted to the inner surface of the annular stop, and the outer surface of the connecting end of the second connector is provided with an external thread, and the second connector is threadedly installed inside the annular stop.

[0008] Preferably, a cylindrical body is provided inside the first connector on the side near the pipe body, and the cylindrical body is located between the pipe body and the baffle.

[0009] Preferably, the side of the cylinder near the baffle is open, and the guide rod passes through the cylinder. One end of the spring is fixedly connected to the inner surface of the cylinder, and the other end of the spring is fixedly connected to the sliding sleeve on the surface of the baffle.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] This invention, by setting up a baffle and a moving mechanism, allows the baffle to move when the first connector and the second connector are disassembled, so that the baffle blocks the first connector, thereby reducing liquid spillage during disassembly and thus reducing pollution.

[0016] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0017] This application discloses an overflow-proof peristaltic pump hose, including a tube body 1. An overflow-proof layer 2 is fixedly sleeved on the surface of the power part of the tube body 1, forming an overflow-proof cavity with the overflow-proof layer 2 and the outer surface of the tube body 1. A pressure detector 3 communicating with the overflow-proof cavity is provided outside the overflow-proof layer 2. Both ends of the tube body 1 are connected to a connecting pipe 4 through an assembly mechanism. The connecting pipe 4 is a preset pipe of the peristaltic pump. The assembly mechanism includes a first connector 5 and a second connector 6. The first connector 5 is fixedly and continuously connected to the tube body 1, and the second connector 6 is fixedly and continuously connected to the connecting pipe 4. A valve body 7 is provided inside the second connector 6. The first connector 5 and the second connector 6 are detachably connected. An annular stop 13 is provided at the opening of the first connector 5. A baffle 9 is connected inside the first connector 5 through a moving mechanism. The diameter of the baffle 9 is larger than the diameter of the annular stop 13 and smaller than the inner diameter of the first connector 5.

[0018] In this embodiment, by setting an anti-overflow layer 2 to cooperate with the pipe body 1, this part of the pipeline has a double-layer structure, which is more robust. Furthermore, by setting a pressure detector 3, when the pipe body 1 is damaged, the pressure in the anti-overflow chamber changes. At this time, after the pressure detector 3 detects the pressure change, the user can close the valve body 7 on the connecting pipe 4 to cut off the pipe body 1 and the connecting pipe 4. In addition, by setting a baffle 9 to cooperate with a moving mechanism, when disassembling the first connector 5 and the second connector 6, the moving mechanism can be used to drive the baffle 9 to move, so that the baffle 9 blocks the first connector 5, thereby reducing the leakage of liquid when disassembling the first connector 5 and the second connector 6, thereby reducing pollution.

[0019] In this embodiment, the tube body 1 and the connecting tube 4 are detachable. The tube body 1 is a part that is easily damaged, and the tube body 1 can be replaced separately to save on usage costs.

[0020] In this embodiment, by setting up structures such as the anti-overflow layer 2 and the baffle 9, liquid overflow can be avoided when the pipe body 1 is damaged.

[0021] Furthermore, the moving mechanism includes guide rods 10 fixedly installed on both sides of the first connector 5. The guide rods 10 are parallel to the central axis of the first connector 5. Sliding sleeves adapted to the guide rods 10 are fixedly connected to both sides of the baffle 9, and the sliding sleeves are sleeved on the surface of the guide rods 10. Springs 12 are sleeved on the surface of the guide rods 10. The springs 12 make the baffle 9 tightly adhere to the annular stop block 13. A push rod 8 is fixedly connected to the connecting end of the second connector 6. When the second connector 6 is connected to the first connector 5, the push rod 8 makes the baffle 9 move away from the annular stop block 13.

[0022] Furthermore, the inner surface of the annular stop 13 is provided with an internal thread, the connecting end of the second connector 6 is adapted to the inner surface of the annular stop 13, and the outer surface of the connecting end of the second connector 6 is provided with an external thread, and the second connector 6 is threadedly installed inside the annular stop 13.

[0023] In this embodiment, when the first connector 5 is connected to the second connector 6, the push rod 8 moves the baffle 9 away from the annular block 13, and the spring 12 is in a compressed state. When the first connector 5 and the second connector 6 are disassembled, the push rod 8 moves out of the first connector 5, the compressed spring 12 extends, thereby driving the baffle 9 to move close to the annular block 13, thereby sealing the first connector 5 and reducing the amount of liquid overflow during disassembly. In addition, a sealing gasket can be provided on the surface of the baffle 9 and the annular block 13 to improve the sealing performance of the baffle 9 in sealing the first connector 5.

[0024] Furthermore, a cylinder 11 is provided inside the first connector 5 on the side near the tube 1. The cylinder 11 is located between the tube 1 and the baffle 9. Furthermore, the side of the cylinder 11 near the baffle 9 is set as an opening, and the guide rod 10 passes through the cylinder 11. One end of the spring 12 is fixedly connected to the inner surface of the cylinder 11, and the other end of the spring 12 is fixedly connected to the sliding sleeve on the surface of the baffle 9.

[0025] In this embodiment, by setting the cylinder 11, the baffle 9 can be prevented from moving to the port of the tube 1, thus ensuring that the port of the tube 1 is open.
