1. A device for alleviating obstructive sleep apnea, configured to be applied to a user's head, the device comprising: a base configured to be fitted and fixed to the user's head and the base having a passage; a suction member having a hollow-cored 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 being cup-shaped and configured to match a transverse outline of the user's tongue, forming a receiving space in communication with the channel and adapted to enclose and receive the user's tongue, wherein the suction member further has a stopping portion configured to be disposed outside the user's oral cavity to limit forward displacement of the tongue fixing portion, wherein the tongue fixing portion is adapted to, under a negative pressure, adsorb to a front end of the tongue and fittingly surround the transverse outline of the user's tongue to form a hermetic seal, such that the negative pressure is configured to act only on the user's tongue, wherein the tongue fixing portion is adapted to move freely together with the user's tongue within the user's oral cavity, wherein, when the user's tongue relaxes, the tongue fixing portion is configured to drive the user's tongue to move forward until the stopping portion stops moving, a resilient element for providing the tongue fixing portion with an elastic force required to approach the base, the elastic force configured to be not only weaker than a suction force between the suction member and the user's tongue but also 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 adapted to provide the 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.
