[0039] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0040] As Figures 1 to 11 shown, in this embodiment, a bottle mouth fixing device for a sparkling water machine is disclosed, which includes a fixing base 1, a bottle mouth joint 2, a pressing structure 3 and a locking structure 4. One end of the bottle mouth joint 2 is detachably connected to the fixing base 1, and the other end is adapted to be connected to the bottle mouth of a gas cylinder 5; an air outlet is provided on the bottle mouth joint 2, and a gas valve 21 which can be opened and closed is arranged at the air outlet; the pressing structure 3 is movably arranged on the fixing base 1 and is adapted to control the opening and closing of the gas valve 21; the locking structure 4 is movably connected to the fixing base 1, and one end is clamped between the bottle mouth joint 2 and the fixing base 1; the other end has a locking position for locking the pressing structure 3 when the bottle mouth joint 2 and the fixing base 1 are not installed in place, and an unlocking position for unlocking the pressing structure 3 when the bottle mouth joint 2 and the fixing base 1 are installed in place.

[0041] When the bottle mouth joint 2 and the fixing base 1 are not installed in place, the locking structure 4 is in the locking position, the pressing structure 3 cannot be pressed and moved, the gas valve 21 is in the closed state and cannot be changed, and sparkling water cannot be made, and no leakage of carbon dioxide gas will occur; when the bottle mouth joint 2 and the fixing base 1 are installed in place, the locking structure 4 is in the unlocking position, the pressing structure 3 can be normally pressed and used, the gas valve 21 can be opened or closed under the control of the pressing structure 3, and the user can normally make sparkling water. The user can also judge whether the gas cylinder 5 is installed in place according to the state of the pressing structure 3, so as to further judge whether there is a possibility of gas leakage, and can timely detect installation defects and avoid gas leakage.

[0042] like Figures 5 to 10 As shown, the bottle mouth fixing device of the sparkling water machine of this embodiment, the bottle mouth joint 2 and the pressing structure 3 are respectively arranged on both sides of the fixing base 1, the locking structure 4 includes a fixing part 41, a slider 42 and a push rod 43, the fixing part 41 is arranged on the side of the pressing structure 3, and is fixedly connected to the fixing base 1, and a sliding hole is provided on the fixing part 41; one end of the slider 42 is slidably arranged in the sliding hole, and the other end cooperates with the pressing structure 3, and has a locking position and an unlocking position; the slider 42 is provided with a pushing hole 423; the push rod 43 is movably connected to the fixing base 1, one end of which is clamped between the bottle mouth joint 2 and the fixing base 1, and the other end is suitable for extending into the pushing hole 423 during the connection process of the bottle mouth joint 2 and the fixing base 1, and pushing the slider 42 to move toward the pressing structure 3.

[0043] The push rod 43 is located between the bottle joint 2 and the fixing seat 1. The movement of the push rod 43 is affected by the bottle joint 2. When the bottle joint 2 is connected to the fixing seat 1, the push rod 43 moves up and extends into the push hole 423, pushing the slider 42 to move to the unlocking position. After the slider 42 moves to the unlocking position, the pressing structure 3 is unlocked, and the bubble water can be made normally. When the bottle joint 2 and the fixing seat 1 are not installed in place, the slider 42 cannot reach the unlocking position, the pressing structure 3 is in a locked state, and the bubble water cannot be made.

[0044] like Figure 7 and Figure 10 As shown, in the bottle mouth fixing device of the sparkling water machine of this embodiment, a first pushing inclined surface 4231 and a limiting surface 4232 are provided on the hole wall of the pushing hole 423 away from the pressing structure 3; the first pushing inclined surface 4231 is connected to the limiting surface 4232 and is located on the side close to the fixing seat 1; and a second pushing inclined surface 4321 cooperating with the first pushing inclined surface 4231 is provided on the push rod 43.

[0045] During the upward movement of the push rod 43, the second push inclined surface 4321 on the push rod 43 applies force to the first push inclined surface 4231 on the push hole 423, and the slider 42 is forced to move in the direction away from the pressing structure 3, and gradually separates from the pressing structure 3, until the second push inclined surface 4321 moves to the limit surface 4232, and the slider 42 is completely separated from the pressing structure 3 and is in the unlocked position. When the push rod 43 moves downward, the second push inclined surface 4321 moves downward from the limit surface 4232 to the bottom of the first push inclined surface 4231, and the first push inclined surface 4231 no longer applies force to the second push inclined surface 4321, and the slider 42 returns to the locked position.

[0046] As a transformable embodiment, it is also possible that a first pushing inclined surface 4231 and a limiting surface 4232 are provided on the hole wall of the pushing hole 423 away from the pressing structure 3, and the second pushing inclined surface 4321 is not provided on the ejector rod 43. Or, the pushing hole 423 is a conventional hole, and the second pushing inclined surface 4321 is provided on the ejector rod 43.

[0047] As Figure 4 As shown in the figure, for the bottle mouth fixing device of the sparkling water machine in this embodiment, the ejector rod 43 includes a collar 431 and a rod body 432. The collar 431 is sleeved on the outside of one end of the bottle mouth joint 2 and is clamped between the bottle mouth joint 2 and the fixed seat 1; one end of the rod body 432 is connected to the outer circumference of the collar 431, and the other end is provided with a second pushing inclined surface 4321.

[0048] The collar 431 is sleeved on the outside of one end of the bottle mouth joint 2 and is clamped between the bottle mouth joint 2 and the fixed seat 1; it can sense the installation between the bottle mouth joint 2 and the fixed seat 1 in the circumferential direction, and the installation not in place in all directions can be detected, making the locking effect of the locking structure 4 better and avoiding gas leakage caused by misdetection resulting in improper installation. Since there is a certain distance between the bottle mouth joint 2 and the pressing structure 3, it is necessary to use the rod body 432 to control the position of the slider 42. In a specific embodiment, a through hole is provided on the fixed seat 1, and one end of the rod body 432 provided with the second pushing inclined surface 4321 passes through the through hole and is arranged at the other end of the fixed seat 1.

[0049] As Figure 2 As shown in the figure, for the bottle mouth fixing device of the sparkling water machine in this embodiment, the locking structure 4 further includes a first elastic member 44. A limiting portion 433 is provided at one end of the rod body 432 connected to the collar 431. The rod body 432 is adapted to be limited on the fixed seat 1 through the limiting portion 433, and the first elastic member 44 abuts between the limiting portion 433 and the fixing portion 41.

[0050] When the bottle mouth joint 2 and the fixed seat 1 are disassembled, the ejector rod 43 moves downward under the action of gravity and the elastic force of the first elastic member 44. The pushing hole 423 is no longer subjected to the thrust of the ejector rod 43, and the slider 42 returns to the locked position, and the pressing structure 3 cannot be used. In a specific embodiment, the first elastic member 44 is a spring, and the spring is sleeved outside the rod body 432 to prevent the spring from bending.

[0051] As Figure 3 As shown in the figure, for the bottle mouth fixing device of the sparkling water machine in this embodiment, the locking structure 4 further includes a second elastic member 45. The slider 42 includes a strip-shaped body 421 and a limiting lug 422. The pushing hole 423 is provided on the strip-shaped body 421; the limiting lug 422 protrudes from the side of the strip-shaped body 421, and the second elastic member 45 abuts between the limiting lug 422 and the fixing portion 41.

[0052] When the bottle mouth connector 2 is disassembled from the fixed seat 1, the ejector rod 43 moves downward under the action of gravity and the elastic force of the first elastic member 44. The pushing hole 423 no longer receives the thrust of the ejector rod 43, and the strip-shaped body 421 returns to the locked position under the elastic force of the second elastic member 45, and the pressing structure 3 cannot be used. In a specific embodiment, both the limiting lug 422 and the fixing portion 41 are provided with protruding columns. The second elastic member 45 is a spring, and both ends of the spring are respectively sleeved on the protruding columns of the limiting lug 422 and the fixing portion 41. In a preferred embodiment, there are two limiting lugs 422, which are respectively arranged on both sides of the strip-shaped body 421. There are two second elastic members 45, and each second elastic member 45 abuts between the limiting lug 422 and the fixing portion 41. The elastic force of the second elastic member 45 is uniform, preventing the slider 42 from skewing during movement and generating noise.

[0053] As Figure 6 , Figure 7 , Figure 9 and Figure 10 shown, for the bottle mouth fixing device of the sparkling water machine in this embodiment, a limiting groove 321 is provided on the side of the pressing structure 3. One end of the strip-shaped body 421 is adapted to extend into the limiting groove 321 to lock the pressing structure 3, and is adapted to be disengaged from the limiting groove 321 under the push of the ejector rod 43 to unlock the pressing structure 3. The limiting groove 321 cooperates with the strip-shaped body 421. When the strip-shaped body 421 is located in the limiting groove 321, it is the locked position of the strip-shaped body 421, and the locking effect is good in the locked position. When the strip-shaped body 421 is located outside the limiting groove 321, it is the unlocking position of the strip-shaped body 421.

[0054] In a preferred embodiment, a reducing slope is provided on the end face of the strip-shaped body 421 close to the limiting groove 321. The reducing slope is arranged at a position close to the bottom of the strip-shaped body 421, which neither affects the locking effect of the top of the strip-shaped body 421 nor reduces the volume of one end of the strip-shaped body 421 due to the existence of the reducing slope, making it easier for the strip-shaped body 421 to extend into the limiting groove 321.
