Description

Technical Field

[0001] This invention relates to the field of electric vehicle technology, and in particular to a gas-liquid separation and drying structure. Background Technology

[0002] A vent valve is a sealed installation component formed by combining a waterproof, oil-proof, and breathable membrane with other materials such as plastics, metals, and silicone through injection molding, ultrasonic welding, or other methods. The main types are threaded and snap-on vent valves. The main performance indicators of a vent valve are air permeability and protection level.

[0003] The waterproof and oil-proof breathable membrane inside the vent valve can prevent water and oil from entering, but it has a certain impact on the breathability of the valve body. Due to the obstruction of the breathable membrane, the air permeability of the vent valve is reduced, so this needs to be improved. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies, such as reduced air permeability of vent valves, by providing a novel gas-liquid separation and drying structure.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] A gas-liquid separation and drying structure includes a motor, a gas-liquid separation valve, a drying box, and an air pipe. The gas-liquid separation valve is mounted on the motor and communicates with the internal space of the motor. The air pipe connects the gas-liquid separation valve to the drying box. The drying box is filled with a desiccant and has a drying air outlet. The gas-liquid separation valve is vertically positioned.

[0007] The gas-liquid separator valve is used to separate gas and oil. It connects to the outside air via a gas pipe and a drying box. The drying box absorbs liquid carried in the gas entering and exiting the separator. This design effectively separates gas and oil inside the motor, while the drying box absorbs moisture from the gas, ensuring the motor's internal dryness and improving its lifespan and performance.

[0008] Preferably, in the gas-liquid separation and drying structure described above, the gas-liquid separation valve includes an upper valve body and a lower valve body. The upper surface of the upper valve body forms a gas pipe connection space. The bottom of the upper valve body is connected to the lower valve body and encloses it to form a separation space. The gas pipe connection space is connected to the separation space. The gas pipe is inserted into the gas pipe connection space. An oil inlet / outlet hole is provided at the lower part of the upper valve body. The oil inlet / outlet hole connects the separation space and the internal space of the motor.

[0009] The gas-liquid separator valve has an interconnected gas pipe connection space and a separation space. Air and oil in the motor enter the separation space through the oil inlet and outlet holes. The gas rises and enters the gas pipe connection space, then enters the drying box through the gas pipe and is discharged.

[0010] Preferably, in the gas-liquid separation and drying structure described above, the upper surface of the lower valve body is provided with an annular boss that extends into the separation space. The upper valve body is provided with a connecting extension that extends into the space enclosed by the annular boss. The connecting extension is provided with a connecting hole that connects the gas pipe connection space and the separation space. The lower surface of the connecting hole is lower than the top surface of the annular boss.

[0011] The lower surface of the connecting hole is lower than the top surface of the annular boss, which prevents the oil from flowing back into the air intake pipe when entering the separation space.

[0012] Preferably, in the gas-liquid separation and drying structure described above, the annular boss is provided with an oil outlet hole.

[0013] The oil outlet is used for the inlet and outlet of oil.

[0014] Preferably, in the gas-liquid separation and drying structure described above, the connecting hole is provided with a valve body support, and the gas pipe abuts against the upper surface of the valve body support.

[0015] The valve body support is designed to prevent the air tube from extending excessively into the gas-liquid separator valve, and also to prevent the desiccant in the drying box from entering the gas-liquid separator valve through the air tube.

[0016] Preferably, in the gas-liquid separation and drying structure described above, the lower valve body has an upward convex center.

[0017] The upward protrusion in the middle of the lower valve body can prevent oil from accumulating in the gas-liquid separator, allowing the oil to flow out naturally under the action of gravity.

[0018] Preferably, in the gas-liquid separation and drying structure described above, the gas-liquid separation valve is provided with a gas pipe sealing plug, which is placed within the gas pipe connection space.

[0019] The tracheal sealing plug serves two purposes: firstly, it reinforces the trachea and the gas-liquid separation valve plug, and secondly, it provides a seal.

[0020] As a preferred embodiment, in the gas-liquid separation and drying structure described above, an oil-draining groove is provided on the top of the upper valve body, and the oil-draining groove is connected to the gas pipe in space.

[0021] The grease trap prevents liquid from accumulating at the top of the gas-liquid separator.

[0022] Preferably, in the gas-liquid separation and drying structure described above, the gas-liquid separation valve is threadedly connected to the motor.

[0023] The gas-liquid separation valve is threadedly connected to the motor, which is simple to connect and the threaded connection can also provide a sealing effect.

[0024] Preferably, in the gas-liquid separation and drying structure described above, the gas-liquid separation valve is provided with a separation valve sealing ring.

[0025] The sealing ring of the separator valve further enhances the sealing performance at the connection between the gas-liquid separator valve and the motor.

[0026] Preferably, in the gas-liquid separation and drying structure described above, the drying box is provided with a drying air inlet, and the air pipe is connected to the drying air inlet.

[0027] The air outlet and air inlet of the drying box are used for ventilation. The air passing through the drying box will have its moisture absorbed by the desiccant, ensuring ventilation while preventing external moisture from entering the motor.

[0028] Preferably, in the gas-liquid separation and drying structure described above, the drying box includes a vent cover and a box body. The vent cover is connected to the box body, the desiccant is placed inside the box body, and a drying air outlet and a drying air inlet are provided on the box body. The vent cover is provided with an air pipe positioning part, the air pipe is connected to the air pipe positioning part, and the air pipe positioning part connects the drying air inlet and the air pipe.

[0029] The vent cover is used to fix the air pipe, so that all air entering and leaving the motor must pass through the desiccant inside the box.

[0030] Preferably, in the gas-liquid separation and drying structure described above, the drying vent is located at the top of the box body, the vent cover covers the drying vent, and the vent cover has a vent hole on its side.

[0031] The vent cover covers the top of the drying vent, and the vent cover has a vent on the side. The gas that is discharged from the drying vent is discharged through the vent on the side of the vent cover. This design can prevent external liquids or debris from entering the box through the drying vent and thus affecting the drying effect of the desiccant.

[0032] Preferably, in the gas-liquid separation and drying structure described above, the drying outlet is provided with a box support.

[0033] The box support is used to prevent the desiccant inside the box from escaping.

[0034] Preferably, in the gas-liquid separation and drying structure described above, the air tube positioning part is provided with a breathable support, and the breathable support abuts against the air tube.

[0035] The ventilated support is designed to prevent the air tube from extending into the box, which would prevent the desiccant inside the box from being used effectively.

[0036] Preferably, in the gas-liquid separation and drying structure described above, the box body is provided with a positioning protrusion, and the vent cover is provided with a positioning groove, wherein the positioning protrusion cooperates with the positioning groove.

[0037] The positioning protrusion cooperates with the positioning groove to fix the vent cover.

[0038] Preferably, in the gas-liquid separation and drying structure described above, the vent cover is provided with an air inlet protrusion, which is inserted into the drying air inlet hole.

[0039] The air intake protrusion can be used to enhance the airtightness of the drying box.

[0040] As a preferred embodiment, in the gas-liquid separation and drying structure described above, the edge of the drying vent hole is recessed on the surface of the box to form an vent groove, and the vent cover is provided with an vent protrusion that is inserted into the vent groove.

[0041] The vented protrusions can enhance the airtightness of the drying box.

[0042] As a preferred embodiment, in the gas-liquid separation and drying structure described above, the box body includes an upper box and a bottom cover, with the bottom of the upper box engaging with the bottom cover.

[0043] The bottom cover facilitates the replacement of the desiccant inside the box.

[0044] Preferably, in the gas-liquid separation and drying structure described above, the vent cover is provided with a motor connection part, and the drying box is connected to the motor through the cooperation of the motor connection part and screws.

[0045] The drying box is connected to the motor via a motor connector and screws, making the connection simple.

[0046] As a preferred embodiment, in the gas-liquid separation and drying structure described above, the drying box is provided with a breathable sealing plug, which is fixed inside the air pipe positioning part and sleeved on the air pipe.

[0047] The vented sealing plug enhances both the stability of the connection between the air tube and the drying box and improves airtightness. Attached Figure Description
