  • Patent number: 11771847
    Abstract: An assembly method of an apparatus suitable for pressurized liquid transfusion is disclosed. In one step, a nozzle is to be inserted into the through hole of an elastomeric ring. Because the dimension of the nozzle is larger than the through hole, the internal wall of the elastomeric ring is tensioned and deformed so as to fit the nozzle. In one step, the elastomeric ring along with the nozzle is inserted into a receptacle. The dimension of the outer contour of the elastomeric ring needs to be decreased so as to be accommodated by the receptacle. Due to the flexibility of the elastomeric ring, it resumes at least partially to its original shape. Therefore, proper seal is created and maintained between the elastomeric ring and the nozzle such that leakage and pressure loss may be prevented. The foregoing is capable of working under high-pressured environment for prolonged use.

  • Patent number: 11752280
    Abstract: An apparatus suitable for pressurized liquid transfusion is disclosed. The apparatus includes a nozzle assembly enclosed by the combination of a casing and a check nut. The nozzle assembly includes an elastomeric ring and a nozzle received by the combination of a cap and a receptacle. The elastomeric ring surrounds the nozzle and a proper seal is created therebetween. The dimension of the internal contour of the elastomeric ring is a bit smaller than the nozzle. The elastomeric ring is stretched so as to receive the nozzle. Additional processing may be applied to the elastomeric ring to achieve a different type of proper seal. Pressurized liquid passes through the apparatus so as to be transfused. The aforementioned seal serves to avoid leakage or pressure loss at the apparatus so as to avoid undesired aerosolization effects of an aerosolizer the apparatus is installed in.

  • Patent number: 11110232
    Abstract: An aerosol generating apparatus is disclosed. The apparatus includes a liquid container, an adaptor detachably engaged with the liquid container, and a driving element accommodated by the adaptor. A perforated membrane, through which a liquid can pass through, is disposed at an exit of the liquid container. Moreover, the perforated membrane faces the driving element. The driving element includes a substrate coupled with a piezoelectric element. The substrate includes an aperture that corresponds to the perforated membrane when the liquid container and the adaptor are engaged so as to receive liquid. Moreover, when the liquid container and the adaptor are engaged, the perforated membrane is in contact with the substrate at the proximity of the aperture, which is about the substrate's center. The adaptor is configured to contact the substrate's periphery only. The resulting apparatus generates aerosol at a desired efficiency with less energy needed.
