【Technical field】

The invention relates to a female hygiene product, in particular to a sanitary napkin.

【Background technique】

Referring to FIG. 1 , a conventional sanitary napkin 1 includes a base material 11 formed with two leak-proof side wings 111 , and an absorbent body 12 protruding from the base material 11 . Although the absorbent body 12 protruding from the base material 11 can fit more closely in the pudendum or groin of the user, so as to quickly absorb secretions and avoid the secretions from flowing backward.

However, due to the lack of positioning effect of the absorber 12, if the user lies on his side or changes his posture, the absorber 12 cannot closely fit the user's pudendum or groin, which greatly affects the function of the absorber 12. .

In order to overcome the above disadvantages, related companies have developed a sanitary napkin 2 as shown in FIG. 2 . The sanitary napkin 2 includes a base material 21 and an absorbent body 22 made of a soft and water-absorbent material. The absorber 22 includes two side wall parts 221 spaced left and right, a central part 222 connected to the side wall parts 221 and spaced up and down with the base material 21, and a The lifting part 223.

Utilize the side wall portion 221 that gradually rises from front to back, so that the central portion 222 and the lifting portion 223 also gradually extend upward from front to back, so that they can closely fit the user’s genitals, and cooperate with the lifting portion 223 Can be clamped and positioned between the user and the base material 21, not only can position the absorbent body 22, but also can absorb secretions overflowing backward. However, due to the lack of breathable design of the absorber 22 structure, it is easy to produce stuffy feeling.

【detailed description】

The present invention will be described in detail below with reference to the drawings and embodiments. Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same numerals.

Referring to Figures 3, 4, and 5, the first embodiment of the sanitary napkin 3 of the present invention includes an absorbent layer 4 defined with a length direction X and a width direction Y perpendicular to each other, and a soft and water-absorbent material. The flow guide unit 5 formed. The flow guide unit 5 includes a flow guide mechanism 51, a pull-up mechanism 52 integrally extended backwards from the flow guide mechanism 51 along the longitudinal direction X and generally in the shape of a strip, and a pull mechanism 52 formed on the flow guide mechanism 51. Position the ventilation mechanism 53 .

The flow guide mechanism 51 has a front end portion 511 at the front, a body portion 512 integrally connecting the front end portion 511 and the lifting mechanism 52, and a plurality of protrusions along the width direction Y, which are left-right symmetrical and along the width direction Y. The flow guiding parts 513 spaced apart from each other in the longitudinal direction X. The positioning ventilation mechanism 53 has a through hole 531 formed in the main body portion 512 , and an auxiliary connecting member 532 located in the through hole 531 . The auxiliary connector 532 has a first connecting end 533 integrally connected to the main body 512 and a second connecting end 534 connected to the absorbent layer 4 , the first connecting end 533 faces the direction of the front end 511 .

Since the flow guiding mechanism 51 is only connected to the absorbent layer 4 by the auxiliary connecting piece 532 of the positioning ventilating mechanism 53, the lifting mechanism 52 can be clamped and positioned between the absorbent layer 4 and the user during practical application. , effectively locate the flow guide mechanism 51 to avoid displacement, and make the body part 512, flow guide part 513 and the lifting mechanism 52 of the flow guide mechanism 51 spaced from the absorbent layer 4 as shown in FIG. Rear upwards, and because the front end 511 is not connected to the absorbent layer 4, therefore, the front end 511 can be tilted up as shown in Figure 5 to touch the user's vulva, and then the flow guiding mechanism 51 The lifting mechanism 52 can be closely attached to the user to enhance the effect of diversion and absorption. And because the body portion 512 of the flow guide mechanism 51, the flow guide portion 513, and the lifting mechanism 52 are spaced from the absorbent layer 4, the perforations 531 formed in the body portion 512 of the flow guide mechanism 51 can be used to make the air Airflow improves breathability and prevents stuffiness.
