This utility model relates to the field of medical device technology, and in particular to a dual-threshold non-contact water level alarm for a ventilator humidifier. It includes a connecting assembly, with an alarm structure fixedly connected to its front end. A first-order sealing plastic sticker is fixedly connected to the right side of the front end of the connecting assembly, and a second-order sealing plastic sticker is fixedly connected to the front end of the first-order sealing plastic sticker. Both the first and second-order sealing plastic stickers are adhered and fixedly connected to the connecting assembly. The alarm structure includes a sensor, with a connecting layer fixedly connected to its front end. Three first-order connectors are fixedly connected at equal intervals laterally at the lower end of the connecting layer. Each of the three first-order connectors has a connecting wire fixedly connected to its lower end, and each of the three connecting wires has a second-order connector fixedly connected to its lower end. This dual-threshold non-contact water level alarm for a ventilator humidifier, through its connecting assembly and alarm structure, facilitates the water level alarm process during ventilator humidification.

The utility model provides a peep-proof film convenient for fingerprint unlocking, which comprises a peep-proof film structure, the peep-proof film structure comprises a peep-proof film layer, a use layer and a transparent adhesive layer, the peep-proof film layer is provided with a through hole for exposing a fingerprint identification module or a transparent film is arranged at a position corresponding to the fingerprint identification module on the peep-proof film layer, and the peep-proof film layer is provided with a transparent adhesive layer. The using layer is adhered to the outer side surface of the peep-proof film layer through (optical) transparent glue, and the transparent adhesive layer is adhered to the inner side surface of the peep-proof film layer. According to the peep-proof film facilitating fingerprint unlocking, the through hole or the transparent film is formed in the peep-proof film layer, the fingerprint unlocking function is not affected, the problem that a traditional peep-proof film is difficult in fingerprint unlocking or cannot be unlocked is solved, the peep-proof film not only has the anti-explosion and anti-scraping functions, but also can effectively prevent peeping, meanwhile, the sensitivity of fingerprint unlocking is not affected, and the peep-proof film is convenient to use. The method is suitable for screen protection of electronic equipment such as smart phones and tablet personal computers.

The utility model discloses a micro differential pressure sensor. The micro differential pressure sensor comprises a substrate, an outer shell and a chip module, the outer shell is fixedly connected with the base plate, and the outer shell and the base plate are enclosed to form an accommodating cavity; the chip module is located in the containing cavity and fixed to the substrate. A pressure equalizing groove is formed in the base plate, an air hole penetrating through the outer shell is formed in the outer shell, and the pressure equalizing groove is matched with the air hole to form a pressure equalizing channel so that the interior of the containing cavity can be communicated with the external environment. Through the arrangement of the technical characteristics, the air leakage efficiency of the micro differential pressure sensor can be improved, and the working reliability of the micro differential pressure sensor is further improved.
