Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted air pumps, in particular to a vehicle-mounted air pump with oxygen supply and inflation functions. Background Art

[0002] With the improvement of people's living standards, self-driving cars are used more and more frequently; when going out, for the sake of convenience and safety, car owners will equip corresponding vehicle-mounted products and emergency products. Vehicle-mounted vacuum cleaners, emergency starting power supplies, air pumps, etc. are all commonly used vehicle-mounted emergency products on the market at present. At present, the functions of vehicle-mounted products are relatively single, and different functions require different products. On the one hand, it causes car owners to need to buy multiple products. On the other hand, multiple products occupy a relatively large storage space in the vehicle. Therefore, it is very important to obtain a multifunctional air pump device.

[0003] A multifunctional air pump device with the publication number of CN221690790U includes a dust collection main body and a handle main body arranged at an angle with the dust collection main body. An installation cavity is formed by internal communication between the dust collection main body and the handle main body. An air suction port and a blowing port are opened on the dust collection main body. A vacuum cleaner motor is arranged between the air suction port and the blowing port. An air pump assembly is arranged in the installation cavity. The handle main body is internally provided with or externally connected with a battery assembly. The battery assembly is connected with a car emergency starting clamp through a wire. The above-mentioned blowing port can not only balance the air pressure in the installation cavity when using the vacuum cleaner function, but also be used as a blowing port to blow air with this component, for example, to realize the operation of blowing dust on the in-vehicle display screen. Compared with the prior art, the beneficial effects of the utility model are as follows: the structure of the utility model is simple, and it has multiple functions such as vacuum cleaning, blowing, inflating, serving as a car emergency starting power supply, lighting, and warning. Only by carrying the utility model in the vehicle can multiple functions be realized.

[0004] The above-mentioned equipment can be effectively used in the conventional vehicle use environment. However, with the rise of self-driving tours, self-driving on the plateau has become an increasingly common phenomenon.

[0005] When off-roading in high-altitude areas, it is often necessary to carry an oxygen generator to provide oxygen for users to relieve the lack of oxygen at high altitudes. At the same time, when driving on the plateau, if passing through deserts, swamps, etc., the tire pressure needs to be lowered to increase the contact area for passage. However, when driving on paved roads, inflation is required to ensure normal tire pressure, and an air pump must be carried, which will increase the weight of the driving equipment and the purchase cost of the equipment. Therefore, it is necessary to improve the existing air pump technology. Summary of the Utility Model
