Abstract

The invention discloses a single-motor double-duct electric mask and belongs to the technical field of electric masks. The single-motor double-duct electric mask comprises a mask body; the mask body includes a fan body, a valve, a first bypass mechanism, a second bypass mechanism and an exhaust port; one side of the mask body is provided with a passage; an empty cavity is arranged in the mask body; one side of the mask body is provided with a circular opening matched with a fan body; the circular opening is positioned in the middle of the passage; the fan body is arranged in the empty cavity via the circular opening; one side of the fan body is provided with a plurality of air outlets at equal intervals; the air outlets are jointly communicated with the passage. Without changing the working condition of the fan body, the first bypass mechanism and the second bypass mechanism are alternated to switch inhaling state and exhaling state; therefore, the problem is solved that the provisionof a single air supply mechanism causes air flowing out of other parts of the mask body.

Description

technical field [0001] The invention relates to an electric mask with single fan and double air channels, which belongs to the technical field of electric masks. Background technique [0002] The existing traditional masks have poor air permeability, and the passing effect is not ideal, because most electric masks only have an air supply structure. As breathing progresses, the air pressure in the internal cavity of the electric mask will increase, which will Cause the exhaled gas to overflow from other parts of the electric mask, affect the use effect, and bring discomfort to the user. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electric mask with single fan and double air ducts, which solves the problem that gas flows out from other parts of the electric mask because the electric mask only needs a single air supply mechanism. [0004] The technical problem to be solved by the present invention takes the ...
