Abstract
Description
Technical Field
[0001] The utility model relates to the field of oil-gas separation devices, in particular to an oil-gas separation device for a motorcycle fuel tank. Background Art
[0002] In the motorcycle tank, the fuel will continue to evaporate as the temperature changes and the vehicle moves, producing fuel vapor. If these vapors are not controlled, they may be directly discharged into the atmosphere, causing environmental pollution. As part of the fuel evaporation control system, the oil-gas separation device is used to capture and store these evaporated fuel vapors to prevent them from being directly discharged into the atmosphere.
[0003] When the existing oil-gas separation device is in use, it is necessary to regularly discharge waste liquid from the liquid discharge end of the device. If it is not discharged for a long time, it will cause internal accumulation and affect the subsequent oil-gas separation. Since the internal phenomena of the oil-gas separation device cannot be viewed from the outside, it needs to be discharged regularly, which increases the complexity.
[0004] In order to solve the above problems, the present application proposes an oil-gas separation device for a motorcycle fuel tank. Utility Model Content
[0005] (I) Purpose of the utility model
[0006] In order to solve the technical problems existing in the background technology, the utility model proposes an oil-gas separation device for a motorcycle fuel tank. The utility model is provided with a self-discharge mechanism so that when the waste liquid at the waste pipe of the separator body increases, it is discharged, and at the same time it plays a role of indicating the need for discharge, thereby playing a role of auxiliary reminder for discharge.
[0007] (II) Technical solution
[0008] In order to solve the above problems, the utility model provides an oil-gas separation device for a motorcycle fuel tank, comprising a separator body, wherein a self-discharging mechanism is provided at the discharge end of the separator body;
[0009] A sealing plug for sealing the discharge end is provided at the discharge end of the separator body.
[0010] Preferably, the self-discharge mechanism includes a discharge pipe, a piston and a spring, the discharge pipe is fixedly connected to the separator body, the piston is slidably sleeved inside the discharge pipe, the piston is connected to the inner wall of the discharge pipe through the spring, and a leak is opened on the discharge pipe.
[0011] Preferably, the piston is fixedly connected to an indicator rod, and one end of the indicator rod slides out of the discharge pipe.
[0012] Preferably, the sealing plug is threadably sleeved with the discharge end of the separator body.
[0013] Preferably, the sealing plug is connected to a scraper ring via a connecting rod.
[0014] The above technical solution of the utility model has the following beneficial technical effects:
[0015] As the waste liquid gradually increases at the waste pipe of the separator main body, the height of the waste liquid continues to increase, and the waste liquid strongly acts on the piston. The piston squeezes the spring to drive the indicator rod to increase the length of the discharge pipe, which plays a role of auxiliary indication, and then feeds back the amount of waste liquid inside the waste pipe of the separator main body. As the piston continues to move away from the separator main body and passes through the leakage port of the discharge pipe, the leakage port plays a role of assisting the discharge of waste liquid. When the user observes the amount of the indicator rod moved out, the blockage can be released by rotating the sealing plug, and the sealing plug can be pulled to drive the connecting rod and the scraper ring to scrape the inner wall of the discharge pipe, thereby increasing the cleanliness and rate of waste discharge.

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.
[0021] like Figure 1-3 As shown, the utility model proposes an oil-gas separation device for a motorcycle fuel tank, comprising a separator body 1, and a self-discharging mechanism 2 is provided at the discharge end of the separator body 1;
[0022] A sealing plug 3 for sealing the discharge end is provided at the discharge end of the separator body 1 .
[0023] In an optional embodiment, the self-discharge mechanism 2 includes a discharge pipe 21, a piston 22 and a spring 23. The discharge pipe 21 is fixedly connected to the separator body 1, and the piston 22 is slidably sleeved inside the discharge pipe 21. The piston 22 is connected to the inner wall of the discharge pipe 21 through the spring 23, and a leak is opened on the discharge pipe 21.
[0024] Furthermore, the piston 22 is fixedly connected to an indicator rod 24 , and one end of the indicator rod 24 slides out of the discharge pipe 21 .
[0025] It should be noted that a scale is provided on the indicator needle 24 so that the volume of the waste liquid inside the waste pipe of the separator body 1 can be judged according to the moving length.
[0026] In an optional embodiment, the sealing plug 3 is threadedly connected to the discharge end of the separator body 1 .
[0027] It should be noted that the threaded connection is used to increase the convenience of blocking or unblocking.
[0028] In an optional embodiment, the sealing plug 3 is connected to the scraper ring 5 via a connecting rod 4 .
[0029] It should be noted that the scraper ring 5 is slidably connected to the waste discharge pipe of the separator body 1 to scrape the waste discharge pipe of the separator body 1.
[0030] In the utility model, as the waste liquid gradually increases at the waste pipe of the separator main body 1, the height of the waste liquid continues to increase, and the waste liquid strongly acts on the piston 22. The piston 22 squeezes the spring 23 to drive the indicator rod 24 to increase the length of the discharge pipe 21, which plays a role of auxiliary indication, and then feeds back the amount of waste liquid inside the waste pipe of the separator main body 1. As the piston 22 continues to move away from the separator main body 1, it passes through the leakage port of the discharge pipe 21, and the leakage port plays a role of assisting the discharge of waste liquid. When the user observes the amount of the indicator rod 24 moved out, the blockage can be released by rotating the sealing plug 3, and the sealing plug 3 can be pulled to drive the connecting rod 4 and the scraper ring 5 to scrape the inner wall of the discharge pipe 21, thereby increasing the cleanliness and rate of waste discharge.
