Hygiene-maintaining device of an underpressure-activated valve for a drinking receptacle

A hygiene-maintaining device of an underpressure-activated valve (2) for a drinking receptacle. Whilst in position of use, the valve (2) encloses a downstream side of an outlet opening (12) in a partition (6) associated with the drinking receptacle. The partition (6) may be a wall portion of the drinking receptacle, or a wall portion of a cap (4) for the receptacle. The valve (2) comprises a movable operating member, a bracing element (24, 70) and a seal member (22) that, whilst in position of rest, seals off said partition opening (12). The operating member is connected to a suction chamber (50) within which an underpressure (P2) may be established in order to activate and move the operating member into a valve-opening position. Thereby, liquid may flow out via the partition opening (12) and further onwards through a liquid outlet path in the valve (2), the operating member being pressure-balanced against the ambient pressure (P1) of the drinking receptacle. The suction chamber (50) is connected to at least one activation opening (52) through which the underpressure (P2) in the chamber (50) may be established. The distinctive characteristic of the invention is that the suction chamber (50) is separated from said liquid outlet path through the valve (2), which fully or partially prevents liquid residues from entering into the suction chamber (50) so as to create subsequent unhygienic conditions therein.

Elevator with air self-purification function

The invention discloses an elevator with an air self-purification function. An air purification mechanism is arranged in a car and comprises a rack, an electrolysis mechanism, an ultrasonic vibrator and a diffusion mechanism. The electrolysis mechanism comprises a water storage chamber used for storing water, a salt water storage chamber used for storing salt water, an extracting and mixing unit, an airflow inductor, a first control unit and an electrolyzer. The extracting and mixing unit is used for extracting the water of the water storage chamber and the salt water of the salt water storage chamber and mixing the water and the salt water in proportion. The airflow inductor is used for inducting the intensity and direction of airflow in the elevator. The first control unit is used for determining the mixing proportion of the water and the salt water according to the intensity and direction, inducted by the airflow inductor, of the airflow, and is connected with the extracting and mixing unit. The electrolyzer is used for electrolyzing a mixed solution of the water and the salt water, and connected with the extracting and mixing unit. Air can be effectively purified, the purification effect is good, and effective purification treatment can be achieved on every corner of the elevator in an omnibearing manner.
