Abstract: A wireless speaker apparatus includes a signal transmission module and a wireless speaker unit. The signal transmission module electrically connects to an audio output of the multimedia device, and is arranged to send out wireless signal corresponding to the audio output. The wireless speaker unit includes a speaker housing configured to stand on a flat surface, a signal receiver, a control circuitry, and a speaker. The signal receiver is arranged to receive wireless signal from the signal transmission module. The speaker electrically connects to the control circuitry, and is configured to deliver audible sound corresponding to the audio output of the multimedia device.

Abstract: A vacuum pump valve includes a valve body and a suction element. 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 hole 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 element 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 mount at the sealing platform at the operation hole to move the sealing head between a releasing position and a sealing position.

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.

Abstract: A remote controlled telephone handset that allows an end user to remotely dial one of at least two telephone numbers stored in the handset. The handset includes a receiver that receives a remote control signal and a memory circuit that is adapted to store at least two telephone numbers. The telephone handset also has a off hook and ring detection circuit that can couple the handset to a telephone line. The receiver, memory and off hook and ring detection circuit are coupled to a central processing unit which can answer an incoming call, hang up a call, or dial one of the telephone numbers in response to the receipt of a control signal(s).

Abstract: A photo-assisted secondary keypad for a telephone. The secondary keypad includes a plurality of openings that expose a number of membrane switch keypads. Depression of a keypad dials a telephone number stored in a memory of the phone unit. Each opening has at least one slot which receives and captures a paper insert. The insert may be a photograph or a graphic image of an individual, police car, etc. The phone numbers associated with each keypad correspond to the images of the inserts. The inserts can be easily installed into the openings by sliding a corner of an insert into the slot.

Abstract: A phone light accessory comprising a light producing element and a conductor element which is integrated into the hand set apparatus of many standard telephone designs.
