Abstract: A telephone handset universal connector is used to connect between a phone base having a set of four signal outlets, and a handset having a set of four corresponding signal ports. The telephone handset universal connector includes a universal circuitry and a selection switch. The universal circuitry has an electric output 101 for electrically connecting with the four signal outlets of the phone base and an electric output 102 for electrically connecting with the four signal ports of the handset, wherein the selection circuitry provides twelve connection combinations for selectively connecting between the four signal outlets and the four signal ports. The selection switch is electrically connected with the selection circuitry to selectively switch the selection circuitry within the twelve connection combinations.

Abstract: A food purifier includes a supporting base having an air outlet, an ozone generator supported in the supporting base for generating a flow of ozone mixing of air to form an airflow towards the air outlet, and a food container, which is supported on the supporting base, having an air inlet and a receiving cavity for containing the water and foods therein. A releasable valve is sealedly mounted at the air outlet of the supporting base for allowing the airflow to pass into the receiving cavity of the food container through the air inlet and for blocking the water from entering into the supporting base. An air dispenser is disposed at a bottom side of the receiving cavity of the food container for diffusing the airflow from the releasable valve to the water so as to guide the airflow in contact with the food.

Abstract: A portable vacuum device for extracting fluid in a container having an opening includes a handheld housing, a fluid extracting nozzle, a vacuum device and a sensor switch. The fluid extracting nozzle has a vacuum pressure corresponding to an interior pressure of the container, extended towards the handheld housing for communicating with the opening of the container. The vacuum device is supported in the handheld housing to generate a vacuum effect within the fluid extracting nozzle. The sensor switch includes a movable conductive member driven with respect to the vacuum pressure of the fluid extracting nozzle and a control member normally positioned spaced apart from the movable conductive member to allow the vacuum device to be operated, wherein when the vacuum pressure drops below a predetermined threshold pressure, the movable conductive member is driven to electrically contact with the control member to deactivate the vacuum device.

Abstract: A vacuum pump valve includes a valve body and a suction diaphragm. The valve body includes a sealing platform sealedly attached on the container at the opening thereof, and a guiding sleeve upwardly extended from the sealing platform to form a suction channel, wherein the sealing platform has an operation slot formed thereon at a position within the suction channel and at least a through ventilating groove communicating the receiving cavity of the container with an exterior thereof. The suction diaphragm is disposed within the suction channel of the valve body, including an enlarged sealing head adapted to seal on the sealing platform to enclose the ventilating groove thereof, and a guiding shaft extended from the sealing head to slidably mounted at the sealing platform at the operation slot to move the sealing head between a releasing position and a sealing position.
