3results about How to "Inflatable effect is good" patented technology

This invention relates to the field of inflatable equipment technology, and particularly to an air valve for manual mouth-blowing air intake and a garment with an inflatable collar using the same valve. The mouth-blowing air valve includes a first air exchange device, a second air exchange device, a regulating device, and a connecting assembly. The first air exchange device has at least two areas with different thicknesses. The second air exchange device has a shape that allows the first air exchange device to fit snugly against it. The area of ​​the second air exchange device that fits against the first air exchange device has a through-hole for ventilation. The regulating device is used to position the first air exchange device. The garment with an inflatable collar includes a garment body and a collar located at the neck of the garment body. The collar has an air bladder and a mouth-blowing air valve that works in conjunction with the air bladder. This invention is easy to operate, has a simple appearance, and is waterproof and dustproof in actual use, providing great convenience for daily life.

The utility model discloses a replaceable air filter core air inlet pressure stabilization chamber, internal combustion engine and unmanned plane, include: the pressure stabilization chamber body, its inside constitution is used for stabilizing the main cavity of airflow, throttle flange, set up in the upstream end of pressure stabilization chamber body, be used for connecting throttle body, air inlet flange, set up in the downstream end of pressure stabilization chamber body, be used for connecting engine, air filter core box, it is connected with the installation mouth of being set up on the pressure stabilization chamber body wall surface in detachable mode to embed in main cavity, air filter core, its accommodation is in the inside of air filter core box, wherein, the airflow of flowing through throttle flange is after entering main cavity, passes through air filter core and filters, finally is transported to engine through air inlet flange.

The utility model discloses a paper-plastic film tearing line mould and paper-plastic film buffer wrappage, the paper-plastic film tearing line mould comprises a cutter body, one side of the cutter body is provided with a first cutter tooth part, a second cutter tooth part and a third cutter tooth part, the other side of the cutter body is provided with a plurality of U-shaped mounting grooves, the first cutter tooth part comprises a plurality of first cutter teeth, the second cutter tooth part comprises a plurality of second cutter teeth, and the third cutter tooth part comprises a plurality of third cutter teeth. The first cutter tooth part comprises a plurality of first cutter teeth, the tooth width of each first cutter tooth is not larger than the tooth pitch of every two adjacent first cutter teeth, the second cutter tooth part comprises a plurality of second cutter teeth, the tooth height of each second cutter tooth is larger than that of each first cutter tooth, the third cutter tooth part comprises a plurality of third cutter teeth, the tooth width of each third cutter tooth is larger than the tooth pitch of every two adjacent third cutter teeth, and the tooth height of each second cutter tooth is larger than that of each third cutter tooth.
