Problems solved by technology

[0002] The existing menstrual cup structure is put into the female vagina and forms a closed space with the vagina. When the menstrual blood is discharged, it will enter this closed space. When the human body is in an upright state, the menstrual blood will flow into and concentrate due to its own weight. In the cup body of the menstrual cup, because the cup body of the menstrual cup is an open structure, the spatial structure changes when the human body is in a lying posture or an upside-down posture, and the menstrual cup becomes horizontal to the vagina or even located on the upper part of the vagina. At this time, the menstrual blood that was originally put into the menstrual cup will flow back into the vagina

Abstract

The invention discloses a backflow preventing menstrual cup, and belongs to the technical field of articles for menstrual period. The menstrual cup comprises a cup body, wherein a cup cavity is formed in the cup body; at the top of the cup cavity, the cup body is provided with a round cup opening; at the opposite side of the round cup opening, a stream guidance pipe is arranged at the bottom of the cup body; a valve is arranged on the stream guidance pipe; a membrane valve, which can seal the round cup opening, is arranged in the cup body; and the membrane valve can be opened in a one-way mode towards the inner side of the cup cavity. According to the backflow preventing menstrual provided by the invention, adding the membrane valve on the basis of a conventional menstrual cup, an effect of one-way sealing is achieved on the inner side of the round cup opening; therefore, when liquid flows into the cup body from the round cup opening, the membrane valve becomes deformed so as to permit the liquid to enter the cup body, while when the cup body is inverted, the liquid in the cup body, due to own gravity, exerts pressure to the membrane valve so as to seal the round cup opening by virtue of the membrane valve, so that a good sealing effect is achieved, and a good backflow preventing function is realized.

Description

technical field [0001] The invention is used in the technical field of sanitary products, and in particular relates to an anti-backflow menstrual cup. Background technique [0002] The existing menstrual cup structure is put into the female vagina and forms a closed space with the vagina. When the menstrual blood is discharged, it will enter this closed space. When the human body is in an upright state, the menstrual blood will flow into and concentrate due to its own weight. In the cup body of the menstrual cup, because the cup body of the menstrual cup is an open structure, the spatial structure changes when the human body is in a lying posture or an upside-down posture, and the menstrual cup becomes horizontal to the vagina or even located on the upper part of the vagina. At this time, the menstrual blood that has been put into the menstrual cup body will flow back into the vagina. Contents of the invention [0003] In order to solve the above problems, the present inv...
