The invention relates to an anti-drowning automatic life-saving necklace and a working method thereof. The necklace comprises an annular collar, on which a plurality of life-saving beads are evenly connected in series. The collar is hollow inside, and a pendant is connected to the bottom end of the collar. The pendant is hollow inside, and a water-expanding object is arranged near the upper end of the pendant. The lower end of the water-expanding object is connected to a steel wire via a movable push rod. The steel wire extends upward into the collar and is connected to the inside of the life-saving bead via a plurality of branch steel wires. The life-saving bead comprises a hemispherical gas cylinder, one branch steel wire of which is connected to the gas cylinder via a gas cylinder switch, the gas cylinder switch is communicated with an air bag via an air inlet pipe, and the other branch steel wire is connected to an upper cover pop-up device. The pendant is provided with a plurality of water inlet holes. The anti-drowning automatic life-saving necklace has a reasonable structure and can effectively protect the life safety of people who cannot swim.

The embodiment of the utility model discloses an externally worn suspender vest with a bra structure, which is characterized by comprising a vest main body and shoulder straps, two ends of the shoulder straps are connected with the vest main body; the vest main body comprises a chest wrapping layer and a waist girdling layer; the chest wrapping layer is used for wrapping the chest of a user; the girdling layer is used for tightening the area from the lower chest edge to the waist of the user; wherein an included angle between a line segment formed from the midpoint of the shoulder strap to the lowest point of the armpit of the breast wrapping layer and a line segment formed from the midpoint of the shoulder strap to the bending point of the neckline of the breast wrapping layer is 23-32 degrees. According to the embodiment of the utility model, the structures of the vest main body and the shoulder straps are adjusted, so that the bearing force of the shoulder straps is stronger. And when facing people with big breasts, a user can wear the underwear more comfortably, and the phenomena of collapse, falling off and the like are avoided.

The utility model provides a light quick-drying garment material, and relates to the technical field of garment materials. Through the multi-layer structural design of the skin-friendly layer, the antibacterial layer, the water guide layer, the protective layer and the anti-static layer which are sequentially compounded from inside to outside, perfect combination of multiple functions is achieved, and the fabric has the remarkable beneficial effects that specifically, the skin-friendly layer is formed by blending cotton fibers and modal fibers, the surface is mercerized through alkali liquor, and the anti-static effect is good; the fabric is softer and more comfortable and has no irritation when being worn next to the skin; the antibacterial layer is formed by interweaving viscose fibers carrying silver ions and bamboo charcoal fibers, the growth of bacteria is effectively inhibited through the synergistic effect of the silver ions and the bamboo charcoal fibers, clothes are kept clean, and the health of a wearer is protected; the water guide layer adopts the double-rib weave woven by the special-shaped section polyester fibers and the spandex fibers, and the section of the fibers is Y-shaped, so that the water guide performance of the fabric is enhanced, sweat can be quickly diffused and evaporated, and clothes are kept dry and comfortable.

The invention provides a bacteriostatic high-end ES composite fiber preparation process and a device thereof.The preparation process comprises the following steps that S1, during use, multiple different silk threads are conveyed into a first silk thread collecting mechanism through a silk thread collecting plate, the multiple silk threads are twisted together, then the multiple silk threads are heated through a heating mechanism, and the multiple silk threads are heated through a second silk thread collecting mechanism; therefore, the silk threads are fused together to form one silk thread; s2, the fused silk threads are cooled through a cooling mechanism, so that the silk thread cooling and shaping effect can be achieved, then the silk threads are guided and stretched through a second silk collecting mechanism, and finally the silk threads are wound through a winding roller; s3, a plurality of different silk threads are prepared from, by weight, 61%-64% of bamboo charcoal fibers, 6%-9% of spandex fibers and 30% of nylon fibers; therefore, the bacteriostatic composite fiber can be formed and manufactured; the bamboo charcoal fiber, the spandex fiber and the nylon fiber can be matched, preparation of the antibacterial composite fiber can be achieved, and the antibacterial composite fiber has antibacterial performance and wear resistance.

The utility model relates to the technical field of wearing equipment, especially earphone, its technical scheme's main point is: including open type loudspeaker part, ear clamping part and ear beam, open type loudspeaker part and ear clamping part set up in the both ends of ear beam respectively, be equipped with the sound hole on open type loudspeaker part, on the horizontal plane projection under the wearing state, the spacing center between open type loudspeaker part and ear clamping part makes a perpendicular center line, the included angle range that the sound hole's sound direction formed with perpendicular center line is 37 degrees 85 degrees, and the application has the directional sound transmission function, makes the sound to be able to complete transmission to the ear canal, and the use experience of earphone is optimized and promotes.

The present invention relates to the technical field of respiratory masks, specifically to an intelligent respiratory mask, comprising: a mask shell, a rubber pressing plate is installed on one side of the mask shell, a cavity is opened in the rubber pressing plate, an inflation port is arranged on the rubber pressing plate, and a fixing belt is installed on the rubber pressing plate to make the rubber pressing plate tightly placed on the human face; a pipe is connected to the side of the mask shell away from the rubber pressing plate, a circular ring plate is fixedly connected in the pipe, the pipe is slidably connected to a connecting plate through a limiting sliding sleeve, a rubber plate is fixedly connected to one side of the connecting plate, and a first filter is fixedly installed on the rubber plate. The parallelogram-shaped groove and sliding column that can be moved up and down cooperate to move the first filter to the outside for easy replacement; the first fan can guide the gas when the mask is in use, so that people can breathe clean and healthy air.
