## Title
Hydration device

## Abstract

A hydration device includes a bag having a water outlet frame connected thereto an outlet connector is connected to the water outlet frame. The outlet connector is connected with a first end of a hose and a second end of the hose is connected to a first end of a mixing unit. A second end of the mixing unit is connected with a mouth piece unit or a two-way switch. The mixing unit is made of flexible material and has a room defined therein. An inner tube is located in the room and connected between a one-way inlet valve and a moisture-water mixing valve. The two-way switch includes a hose mount, a main part, a sealing unit and a release unit, wherein the user can have water directly from the sealing unit and the water can be dispensed to share with others by operation of the release unit.

## Background
FIELD OF THE INVENTION
The present invention relates to a hydration device wherein the user can introduce pressure into the water bag so that the water is supplied by the pressure in the water bag.
BACKGROUND OF THE INVENTION
One of the conventional personal hydration devices uses pressure to allow the users to have sufficient water from the device, and generally includes a bottle, a control switch, a hose and compressing unit. The hose and the compressing unit are sealed to the bottle which forms an air-tight space, wherein the hose and the compressing unit are in communication with the space. The control switch is connected with the hose. The compressing unit can be a pressurized tank and the control switch is a push-type switch or a threading-type switch. By introducing pressure into the bottle, the water in the bottle can be supplied to the user's mouth via the operation of the control switch. Another conventional personal hydration device is disclosed in US2008/0308578A1, and includes a reservoir having an air inlet and water outlet, the air inlet can be operated by using pump or squeezing an air bladder to increase pressure in the reservoir. A hose is connected to the water outlet and a mouth piece is connected the other end of the hose, or the hose is connected between the air bladder and the water outlet. The hose can be switched to provide pressure to the water in the reservoir. Both of the two published hydration devices include two individual pumping part and drinking part, and are connected to the reservoir. This increases the manufacturing cost and is inconvenient for carriage. During operation, the pumping action and the drinking action are two separated actions, and the water can only be obtained when there is sufficient pressure. If the pressure is too low, the water cannot be completely expelled. When the pressure is sufficient and the water is full, the water will flow so fast that the user get choke on water. When the water is less and the pressure will be low so that the water flows slow and cannot meet the user's need.
The present invention intends to provide a hydration device which improves the problems of the conventional hydration devices and the water supplying device can be increased the pressure in the water bag to improve the speed of the water flow so as to convenient have the water from the water bag.

A hose connector 3211 is connected to a top end of the first inlet member 321 and an air inlet chamber 3212 is connected to a lower end of first inlet member 321. The air inlet chamber 3212 has outer threads 3214 defined in an outer surface thereof and an air inlet hole 3213 is defined through a wall of the air inlet chamber 3212. An enlarged opening 3215 is defined in an underside of the air inlet chamber 3212. The communication tube 322 has a top tube 3224 connected to a top end thereof so as to press the inlet valve 323 against a top end of the air inlet chamber 3212. A lower end of the communication tube 322 has an inner tube connector 3222 which is connected with the inner tube 34 such that the first inlet member 321 communicates with the communication tube 322 to form a water path. The flange 3221 has an aperture 3223 which communicates with the air inlet chamber 3212 and the room 310. The moisture-water mixing valve 33 comprises a second inlet member 331, a connection member 332, a mixing valve 333 and a collar 334. The second inlet member 331 has an inner tube connector 3311 connected to a top end thereof so as to be connected with the inner tube 34. A mixing chamber 3312 is connected to a lower end of the second inlet member 331 and includes an inlet hole 3313 defined therein and an insertion portion 3314 is located at a mediate portion of the mixing chamber 3312. The mixing valve 333 is mounted to the insertion portion 3314 so as to seal the inlet hole 3313.
