The connector 100 is further provided with a rotatable operating member, a rotation-translation conversion mechanism is arranged between the operating member and the air outlet member 5, and the rotation-translation conversion mechanism can convert the rotation of the operating member into the internal and external movement of the air outlet member 5.

The operating element is a handle 7 hinged on the cover body 4, the handle 7 has a laying-down state and a fully lifting state, and the air outlet element 5 blocks the conduction of the air bottle 2 and the air outlet structure 115 (see figure 6) when the handle 7 is in the fully lifting state; handle 7 is under the state of putting down, gas outlet member 5 switches on gas cylinder 2 and the structure 115 of giving vent to anger (see fig. 4), when getting the gas cylinder subassembly in holding chamber 11 like this, snatch the inevitable lifting and putting down that can involve handle 7 of gas cylinder subassembly, make handle 7 put down or mention completely through rotating handle 7, switch the state of switching on of gas cylinder 2 and the structure 115 of giving vent to anger and block the state, the messenger snatchs the gas cylinder subassembly, gas outlet member 5 switches on or blocks gas cylinder 2 and the structure 115 of giving vent to anger, these two can put in place by one step, other extra actions are not needed, thereby make installing and removing of gas cylinder subassembly more convenient.

As shown in fig. 4, the air outlet channel 31 is provided with an air valve 9 for controlling air outlet of the air bottle 2. The front side of the cover body 4 is provided with a third opening 44, a rocker switch 8 for controlling the opening and closing of the air valve is arranged in the cover body 4, and the rocker switch 8 passes through the third opening 44 and penetrates out of the joint 100. The front side wall of the housing 1 is further opened with a notch 116, and when the gas cylinder assembly is placed in the accommodating cavity 11, the rocker switch 8 can extend to the outside of the housing 1 through the notch 116, so that the rocker switch 8 is operated to open the gas valve 9. The structure of the air valve 9 and the action principle of the rocker switch 8 for controlling the air valve 9 refer to the prior art.

The left side wall and the right side wall of the cover body 4 are respectively provided with a shaft hole 43 (see figure 7), each shaft hole 43 is internally provided with a rotatable transmission piece 6, the outer end of each transmission piece 6 is respectively fixedly connected with the corresponding end of the handle 7, the rotation-translation conversion mechanism comprises a gear part 61 arranged at the inner end of each transmission piece 6 and rack parts 52 arranged on the air outlet pipe 5 and positioned at two sides of the air outlet pipe 51, and each rack part 52 extends along the front-back direction and is respectively meshed with the corresponding gear part 61 (see figure 2), so that the rotation of the handle 7 drives the transmission piece 6 to rotate, and further the rack parts 52 are driven to drive the air outlet pipe 5 to move, and the rotation-translation conversion mechanism is simpler. Two sliding grooves are formed in the top of the joint base 3 at intervals, each sliding groove extends horizontally, and each rack portion 52 is slidably disposed in the corresponding sliding groove. One side of the cover body 4 is recessed with a receiving groove 42, and the handle 7 is seated in the receiving groove 42 in a laid-down state (see fig. 5 and 6), so that the handle 7 is conveniently received. The gas cylinder of device is prepared to aerated water installs and removes structure fast in this embodiment, can allow to accomplish earlier 2 and connect 100 being connected of gas cylinder in the bigger casing in space 1 outside, it is more convenient to make the installation of gas cylinder 2, arrange the gas cylinder subassembly in holding chamber 11 again, can avoid 2 external gas cylinders, can not only make the aerated water prepare the device more pleasing to the eye, thereby it is better still to make 2 gas cylinders be difficult to be touched by the mistake and make the leakproofness that the device gas circuit was prepared to the aerated water, still realize switching on or blocking of gas cylinder 2 and the structure 115 of giving vent to anger through controlling the operating parts, it is more convenient to make 2 loading and unloading operations of gas cylinder.

The gas cylinder of the aerated water preparation device in the embodiment is quickly assembled and disassembled according to the assembly and disassembly principle that:

when the gas cylinder 2 needs to be replaced, the handle 7 is grabbed, and the handle 7 is rotated upwards clockwise (downwards in the left view, namely according to the figure 3) to a complete lifting state. During the upward rotation of the handle 7, the transmission piece 6 rotates clockwise synchronously with the handle 7, drives the rack portion 52 to move backwards, and drives the air outlet pipe 51 to move backwards, so that the air outlet pipe 51 is separated from the air outlet structure 115 and retracts into the mounting base 100, and the air bottle 2 is blocked from the air outlet structure 115. The gas cylinder assembly is lifted upward to take out the gas cylinder assembly from the accommodating chamber 11. Subsequently, the gas cylinder 2 is rotated to separate the gas cylinder 2 from the joint base 3, thereby detaching the gas cylinder 2 from the joint 100.

A new gas cylinder 2 is taken and the gas cylinder 2 is rotated to connect the gas cylinder 2 with the joint socket 3, thereby mounting the gas cylinder 2 on the joint 100. The grasping handle 7 places the gas cylinder assembly into the receiving cavity 11 through the first opening 114, so that the joint 100 rests on the step 113 and is located in the upper chamber 111, and the gas cylinder 2 is located in the lower chamber 112. Subsequently, the handle 7 is rotated counterclockwise (downward in the left-side view, i.e., according to fig. 3) to be seated in the receiving groove 42, so that the handle 7 is in a lowered state. In the process that the handle 7 rotates downwards, the transmission piece 6 rotates anticlockwise synchronously with the handle 7, drives the rack portion 52 to move forwards, and drives the air outlet pipe 51 to move forwards, so that the air outlet pipe 51 penetrates out of the joint 100 through the second opening 41 and is inserted into the air outlet structure 115, and the air bottle 2 is communicated with the air outlet structure 115. Finally, the rocker switch 8 is pressed to open the air valve 9 by the rocker switch 8, so that the gas in the gas cylinder 2 can flow out through the gas outlet structure 115.

It should be noted that in the description of the present embodiment, the terms "front, back", "left, right", "upper, lower", "clockwise", "counterclockwise", etc. indicate the orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
