The head is disposed on the mouth and includes a main body having outlet, inlet, and communication channels, a handle, and a pressure-relief device disposed in the communication channel and including a stopper, an elastic member for driving the stopper to block communication between the outlet channel and the communication opening, and a ring located above the outlet channel and sleeving the stopper. The handle is pivoted to the main body and inserted into the stopper for moving the stopper upward. When an internal pressure of the bottle body is greater than a predetermined value, the stopper is moved upward by the internal pressure to make the outlet channel communicated with the communication opening. ## Claims ### Claim 1 A bubble liquid bottle comprising: a bottle body having a mouth, the bottle body being used for containing liquid; a pad covering the mouth of the bottle body and having a communication opening; a straw connected to the communication opening and inserted into the bottle body; and a head disposed on the mouth and covering the pad, the head comprising: a main body having an outlet channel, an inlet channel, and a communication channel, the outlet channel being communicated with the communication opening via the communication channel, the inlet channel being communicated with the communication channel and being used for connecting to a gas filling bottle so as to make gas provided by the gas filling bottle enter the bottle body via the communication opening and then dissolve in the liquid contained in the bottle body to generate a bubble liquid; a pressure-relief device disposed in the communication channel, the pressure-relief device comprising: a stopper movably disposed in the communication channel; an elastic member disposed in the communication channel and abutting against the stopper for providing an elastic force to drive the stopper to block communication between the outlet channel and the communication opening; and a ring sleeving the stopper, the ring being located above the outlet channel for preventing the bubble liquid or the liquid from overflowing out of the communication channel; and a handle pivoted to the main body and inserted into the stopper for moving the stopper upward along the communication channel when the handle is pressed so as to make the bubble liquid driven by an internal pressure of the bottle body to flow out of the outlet channel through the straw, the communication opening, and the communication channel; wherein when the internal pressure of the bottle body is greater than a first predetermined value, the stopper is driven to move upward by the internal pressure of the bottle body, so as to make the outlet channel communicated with the communication opening. ### Claim 2 (depends on 1) The bubble liquid bottle of claim 1, wherein the inlet channel has a connection opening, and the head further comprises: a cover detachably connected to the connection opening, the gas provided by the gas filling bottle entering the bottle body via the communication opening and then dissolving in the liquid contained in the bottle body to generate the bubble liquid when the cover is detached from the connection opening and the gas filling bottle is then connected to the connection opening; and a check valve disposed in the inlet channel for blocking communication between the inlet channel and the communication opening when a filling pressure of the gas filling bottle is greater than or equal to a second predetermined value. ### Claim 3 (depends on 1) The bubble liquid bottle of claim 1, wherein a guiding slot is concaved from an inner wall of the outlet channel. ### Claim 4 (depends on 1) The bubble liquid bottle of claim 1 further comprising: a liquid level sleeve disposed through the mouth and suspended in the bottle body, the straw penetrating the liquid level sleeve to be inserted into the bottle body, the liquid being driven by the internal pressure to flow into the liquid level sleeve when a level of the liquid is higher than a bottom of the liquid level sleeve. ### Claim 5 (depends on 1) The bubble liquid bottle of claim 1, wherein the head is locked with the mouth in a trapezoid-tooth engaging manner. ### Claim 6 (depends on 1) The bubble liquid bottle of claim 1, wherein a bulge structure is formed inwardly from a bottom of the bottle body. ### Claim 7 (depends on 1) The bubble liquid bottle of claim 1, wherein the liquid is water, and the gas is carbon dioxide. ### Claim 8 (depends on 1) The bubble liquid bottle of claim 1, wherein the bottle body is made of stainless steel material. ### Claim 9 (depends on 1) The bubble liquid bottle of claim 1, wherein a diameter of the mouth is between 36 mm and 46 mm. ### Claim 10 (depends on 1) The bubble liquid bottle of claim 1, wherein the pad, the straw, and the main body are doped with antiseptics.
