Description
Technical Field
[0001] The utility model belongs to the technical field of valves, and particularly relates to an adjustable micro-air oxygen outlet device for an in-vehicle oxygen supply system of a new energy vehicle. Background Technique
[0002] With the rapid popularization of new energy vehicles, users' demands for vehicle cockpit functions are becoming increasingly diverse. Optimizing the oxygen supply in the cockpit has become an important part of enhancing the driving experience. For example, in congested urban roads, the air quality outside the vehicle is poor and it is not suitable to open the window for ventilation, which easily leads to a decrease in the oxygen concentration inside the vehicle; when driving in high-altitude areas, the environmental oxygen concentration is low, and the demand for in-vehicle oxygen supply is more urgent. The existing in-vehicle oxygen supply systems generally adopt fixed oxygen outlet devices, which have the following technical defects: (1) The oxygen outlet air flow is not adjustable: The air flow rate of the existing oxygen outlet devices is fixed and cannot be adjusted according to the needs of the occupants or environmental changes. For example, users cannot increase the oxygen supply in a low-oxygen environment or reduce the air flow to save oxygen resources when a large amount of oxygen supply is not required. (2) The oxygen outlet angle is fixed: The spraying angle of the oxygen outlet device cannot be adjusted, resulting in uneven oxygen distribution and difficult to meet the personalized needs of different occupants.
[0003] In response to the above problems, the solutions adopted in the prior art are to improve the oxygen supply effect by increasing the volume of the oxygen supply equipment or using complex air flow control valves. However, the cockpit space of new energy vehicles is limited, and it is difficult to install large oxygen supply equipment; and the complex valve structure not only has a high cost but also is cumbersome to operate, making it difficult to meet the users' requirements for lightweight and ease of use. Therefore, there is an urgent need for an adjustable micro-air oxygen outlet device for an in-vehicle oxygen supply system of a new energy vehicle with adjustable oxygen outlet air flow and oxygen outlet angle to solve the above problems.
