2. A device for alleviating obstructive sleep apnea, comprising: a base configured to be fitted and fixed to a user's head and the base having a passage; a suction member having a channel extending and passing through the passage to enter the user's oral cavity and undergo displacement within the passage, with the channel connected to a tongue fixing portion, the tongue fixing portion configured to be disposed at a front end of the user's tongue, wherein the suction member has a stopping portion for limiting forward displacement of the tongue fixing portion; a resilient element for providing the tongue fixing portion with an elastic force required to approach the base, the elastic force configured to be both weaker than a suction force between the suction member and the user's tongue and weaker than a pulling force configured to be generated by the user's tongue in tongue motion; a negative pressure source in communication with the channel and configured to provide a negative pressure to the user's tongue in contact with the tongue fixing portion; and an adjustment element configured to be disposed outside the user's oral cavity, connected to the base, and capable of moving forward and rearward relative to the base, wherein the resilient element is received in the adjustment element, and the resilient element has an end connected to the adjustment element, wherein an extent to which the resilient element is stretched or compressed remains unchanged in the course of forward and rearward movement of the adjustment element relative to the base.
