The present invention discloses a spinning fiber negative potential ion deriving device comprising a base, a spray device and a cotton thread； the spray device is arranged above the base, the cotton thread is inserted on one side of the base； the base comprises a female terminal , a vent, a fiber line jack and a three-stage switch. The female terminal is recessed on the upper end of the base； the air hole is disposed at the front end of the base for outputting a first negative ion； the fiber wire jack is disposed at the rear end of the base for inserting the cotton wire and outputting a first Two negative potential ion fibers； a three-stage switch is disposed at the front end of the base for switching the base to output the first negative ion or the second negative potential ion fiber. The negative ion output of the creation can be transmitted to the mask for the user to wear the mask without suffocating and can directly purify the fresh air, and the device itself has a safe electric field characteristic that the natural (non-electromagnetic wave) fiber line conducts a negative potential when the circuit operates. In addition, it has a spray effect capable of performing atomization of the liquid, effectively increasing the amount of negative ion release and the health and mental state of the user, and improving the air purification of the environment around the user and enhancing the balance of the ion potential in the body.本創作公開一種紡纖負電位離子導出裝置，包括有一基座、一噴霧裝置及一棉線；噴霧裝置設置在基座上方，棉線插接於基座的一面上；基座中包括有一母端端子、一氣孔、一纖維線插孔以及一三段式開關。母端端子是凹設於基座的上端；氣孔設於基座的前端，用以輸出一第一負離子；纖維線插孔設於該基座的後端，用以插接棉線且輸出一第二負電位離子纖維；三段式開關設於該基座的前端，用以切換該基座輸出該第一負離子或該第二負電位離子纖維。本創作的負離子輸出能傳導到口罩供使用者戴口罩不悶並可直接淨化呼吸清新空氣，以及裝置本身於電路運作時會具有天然(無電磁波)纖維線傳導出負電位之安全電場特性，再加上具有能夠執行將液體霧化的噴霧效果，有效地提升負離子釋放量與使用者的健康及精神狀態，且增進使用者周遭環境的空氣淨化與提升體內離子電位平衡的清新舒暢感。
