It is further comprises an exhaust structure comprising an exhaust hole penetrating the body, whereby exhaust air flow can escape via the exhaust hole to outside the bottle. ## Claims ### Claim 1 A portable chargeable bottle comprising: a body having an upper part and a lower part; a dispensing mechanism provided at the upper part; and a liquid charging structure provided at the lower part, wherein said lower part of the bottle is configured to incorporate part of an exhaust structure, wherein the liquid charging structure comprises: a stepped liquid charging mouth at said lower part; a protuberant piston provided to the liquid charging mouth; and a resetting structure of the piston, wherein a liquid charging passage is arranged in the piston and is fitted with a discharging opening, wherein a stop block with one flared end is provided on a top of the piston, and wherein a first sealing ring capable of performing sealing is arranged on the stop block. ### Claim 2 (depends on 1) The bottle of claim 1, wherein at least one exhaust hole is provided to the lower part of the bottle that corresponds to a groove on the piston, and wherein said exhaust structure further comprises an air duct interconnected with the exhaust hole and extending to the upper part of the bottle, and a gap between the piston and the body, whereby at uncharged state the sealing ring blocks a gap from the air duct. ### Claim 3 (depends on 2) The bottle of claim 2, wherein a second sealing ring is provided in the groove of the piston sealing said air duct from said exhaust hole, wherein when said piston is pushed inwardly, said second sealing ring is moved so as to allow air to outwardly escape through said exhaust hole. ### Claim 4 (depends on 1) The bottle of claim 1, wherein at least one exhaust hole is provided in the lower part of the bottle and wherein said exhaust structure is further provided with an air duct interconnected with the exhaust hole and extending to the upper part of the bottle, and a gasket is provided at a bottom of the exhaust hole. ### Claim 5 (depends on 4) The bottle of claim 4, wherein the gasket comprises silicon rubber. ### Claim 6 A portable chargeable bottle comprising: a body having an upper part and a lower part; a dispensing mechanism provided at the upper part; and a liquid charging structure provided at the lower part, wherein said lower part of the bottle is configured to incorporate part of an exhaust structure, wherein at least one exhaust hole is provided in the lower part of the bottle, wherein said exhaust structure is further provided with an air duct interconnected with the exhaust hole and extending to the upper part of the bottle, wherein a gasket is provided at a bottom of the exhaust hole, and wherein the gasket further comprises at least one pore extending therethrough, whereby pressurized air inside the bottle impels the pores to have a radial extension, such that the pores are enlarged and the pressurized air can be drained away via the exhaust hole, and when exhaust is complete, the gasket resets to block and seal the exhaust hole. ### Claim 7 (depends on 4) The bottle of claim 4, wherein the liquid charging structure comprises a stepped liquid charging mouth at the lower part of the bottle, a protuberant piston equipped on the liquid charging mouth, and a resetting structure of the piston, wherein a liquid charging passage is arranged in the piston and is fitted with a discharging opening. ### Claim 8 (depends on 1) The bottle of claim 1, wherein the liquid charging structure comprises a liquid charging mouth at the lower part of the bottle, a spring and a bead, wherein the spring is configured to urge the bead thereby sealing off the interior of the bottle from the charging mouth, and to be elevated when filling the bottle, wherein the bead no longer blocks the charging mouth and thereby allows liquid into the bottle, and wherein the exhaust structure comprises an exhaust hole provided in the lower part of the bottle, and an air duct interconnected with the exhaust hole and extending to the upper part of the bottle, wherein a bead is equipped at the bottom of the exhaust hole and on a compression spring, and the compression spring is set in the lower part of bottle. ### Claim 9 (depends on 1) The bottle of claim 1, wherein the liquid charging structure comprises a liquid charging mouth at the bottom of the bottle, and a piston comprising a bottom pliable and resilient part and a top hard part to which the bottom pliable part is permanently attached, whereby the bottom pliable part, when not forced upward, seals off the interior of the bottle from the charging mouth, and when forced upward, the bottom pliable part is compressed, allowing liquid to enter the bottle via at least one gap between the piston and a wall of the bottle defining the charging mouth. ### Claim 10 (depends on 9) The bottle of claim 9, wherein the exhaust structure comprises an exhaust hole provided on the lower part of bottle and an air duct interconnected with the exhaust hole and extending to the upper part of the bottle, wherein a gasket is provided at the bottom of the exhaust hole. ### Claim 11 (depends on 10) The bottle of claim 10, wherein the gasket comprises silicon rubber. ### Claim 12 (depends on 10) The bottle of claim 10, wherein the gasket further comprises at least one pore extending therethrough, whereby pressurized air inside the bottle impels the pores to have a radial extension, such that the pores are enlarged and the pressurized air can be drained away via the exhaust hole, and when exhaust is complete, the gasket resets to block and seal the exhaust hole.
