Description

Technical Field

[0001] The present invention relates to the technical field of anti-motion sickness, and in particular to a vehicle-mounted anti-motion sickness device and a control method. Background Art

[0002] Motion sickness is a common physiological phenomenon. During the driving process, especially when the car is frequently started and braked, it is easy for the passengers to experience nausea, dizziness, cold sweats and other discomfort symptoms. Some people who are not used to riding in a car may even vomit, which not only brings pain to the individual, but may also affect work efficiency and travel quality, and even affect driving safety in some cases. Although opening the window to breathe fresh air can effectively relieve motion sickness, it may affect other passengers, causing them to feel cold and uncomfortable, and vomitus will also dirty the car. The unpleasant smell and unsightly vomit will seriously affect the riding experience of other passengers in the car.

[0003] Currently, the main methods available on the market for preventing motion sickness include taking motion sickness medication, wearing motion sickness patches, and using natural relief methods such as ginger or lemon. However, motion sickness medication can cause side effects such as drowsiness, which can affect daily activities. While motion sickness patches can relieve symptoms, some people may be allergic to their ingredients. Traditional natural remedies, on the other hand, can be effective from person to person, making consistent results difficult to guarantee.

[0004] At the same time, there are also many devices designed to prevent motion sickness. Among them, the Affiliated Hospital of Hangzhou Normal University (Hangzhou Second People's Hospital) has proposed an anti-motion sickness mask (publication number: CN 220675223 U). This mask helps alleviate motion sickness symptoms by installing an adjustable motion sickness patch (containing medicinal ingredients) on the mask. The motion sickness patch is connected to the tension strap of the mask via a connector, and its position can be adjusted according to user needs to provide a personalized user experience. The mask itself contains multiple layers, such as a non-woven fabric layer, a meltblown fabric layer, and a pharmacological layer. The pharmacological layer contains anti-motion sickness extracts such as calamus, datura, and Uncaria rhynchophylla to enhance the anti-motion sickness effect.

[0005] Nanjing Seeler Automotive Electronics Co., Ltd. has proposed a new type of anti-motion sickness massage chair for cars and its massage method (CN 113335165A). This invention performs acupoint massage on the neck and hands of people who suffer from motion sickness. The massage rollers are driven by electric pressing components and micro motors to simulate the massage effect of human hands and alleviate the symptoms of motion sickness. The mounting base of the seat can be adjusted in height, and the massage bracket moves according to the position of the person who suffers from motion sickness, ensuring that the massage can accurately act on the required acupoints. In addition, the airbag cushion and air pump system can adjust the inflation and deflation according to the user's pressure data to achieve comfortable curvature adjustment. However, this invention requires a more sophisticated design and also requires a larger economic investment.

[0006] Zunyi Southern Liquor Secondary Vocational School has also developed an anti-motion sickness mask (publication number CN 211021068 U). This mask features popping beads containing anti-motion sickness flavorings (such as orange peel, ginger, mint, and lemon). When the user experiences motion sickness, they can squeeze the popping beads to release the flavorings, alleviating the discomfort.

[0007] Jinxu Environmental Protection Products (Shenzhen) Co., Ltd. has developed a novel biomass fiber anti-motion sickness mask (publication number CN208783818U). This mask features a replaceable, specially crafted scent patch that emits a scent containing anti-motion sickness ingredients to alleviate motion sickness symptoms. The scent patch can be made from fruit, floral, and certain medicinal ingredients, is non-toxic, and can help alleviate discomfort for passengers.

[0008] Based on the above situation, the current anti-motion sickness devices have the following problems: anti-motion sickness masks are basically disposable, and each mask needs to be designed with a layered and pharmacological layer, which has high economic costs and is not sustainable. In addition, some anti-motion sickness masks also have certain requirements for the user's body shape. Summary of the Invention
