[0013] The beneficial effects of this utility model are as follows: This solution incorporates a locking device between the sparkling water machine body and the gas cylinder cover. The locking device includes a locking switch and a locking position, which are respectively located on the sparkling water machine body and the gas cylinder cover. The locking switch includes a locking element, a driving part, and a return spring. When the gas cylinder cover is installed on the sparkling water machine body, the locking element engages with the locking position under the action of the return spring. Simultaneously, the relative movement direction between the locking position and the locking element opposes the movement direction of the gas cylinder cover when it is removed from the mounting base. Therefore, after the locking element engages with the locking position, the gas cylinder cover cannot move in the direction of removal from the mounting base, thus fixing the gas cylinder cover to the sparkling water machine body. When it is necessary to remove the gas cylinder cover, the driving part needs to drive the locking switch to move, thereby disengaging the locking element from the locking position, allowing the gas cylinder cover to be removed smoothly. Compared with existing technologies, this is safer. Attached Figure Description

[0026] Reference Figures 1 to 7 A sparkling water machine with a gas cylinder cover designed to prevent it from falling off, comprising:

[0027] The sparkling water machine body 10 is provided with a mounting base 11. The mounting base 11 is provided with a cylinder mounting port for connecting to a carbon dioxide cylinder. The mounting base 11 is detachably provided with a cylinder cover 20 for fitting the carbon dioxide cylinder inside it.

[0028] A locking device is provided, comprising a locking switch 30 and a locking position. The locking switch 30 is provided with a locking element that movably engages with the locking position. The locking switch 30 is provided with a return spring 40 that drives the locking element to move toward the locking position. The locking switch 30 is provided with a driving part that drives the locking element to move against the return spring 40. The locking switch 30 and the locking position are respectively provided on the main body 10 of the sparkling water machine or the gas cylinder cover 20. When the gas cylinder cover 20 is installed on the mounting base 11, the locking element engages with the locking position under the action of the return spring 40. The relative movement direction of the locking position and the locking element is opposite to the movement direction of the gas cylinder cover 20 when it is removed from the mounting base 11.

[0029] This solution incorporates a locking device between the sparkling water machine body 10 and the gas cylinder cover 20. The locking device includes a locking switch 30 and a locking position, which are respectively located on the sparkling water machine body 10 and the gas cylinder cover 20. The locking switch 30 includes a locking element, a driving unit, and a return spring 40. When the gas cylinder cover 20 is installed on the sparkling water machine body 10, the locking element engages with the locking position under the action of the return spring 40. Simultaneously, the relative movement direction between the locking position and the locking element opposes the movement direction of the gas cylinder cover 20 when it is removed from the mounting base 11. Therefore, after the locking element engages with the locking position, the gas cylinder cover 20 cannot move in the direction of removal from the mounting base 11, thus fixing the gas cylinder cover 20 to the sparkling water machine body 10. When it is necessary to remove the gas cylinder cover 20, the driving unit drives the locking switch 30 to move, thereby disengaging the locking element from the locking position, allowing the gas cylinder cover 20 to be removed smoothly. This method is safer than existing technologies.

[0030] In the above scheme, preferably the locking switch 30 is disposed on the main body 10 of the sparkling water machine, the driving part is disposed on the surface of the main body 10 of the sparkling water machine, and the locking position is disposed on the gas cylinder cover 20.

[0033] In the above scheme, preferably, the outer periphery of the mounting base 11 is provided with a plurality of locking pins 111, and the inner side of the gas cylinder cover 20 is provided with a plurality of vertical entry grooves 22 and a transverse rotation groove 23 located at the end of the vertical entry groove 22 and arranged laterally. The width of the locking pins 111 is not greater than the width of the vertical entry groove 22. When the gas cylinder cover 20 is fitted onto the outer periphery of the mounting base 11, and the locking pins 111 move along the vertical entry groove 22 to the end of the vertical entry groove 22 and then rotate to the end of the transverse rotation groove 23, the locking pins 31 are aligned with the locking grooves 21.

[0034] In another embodiment, the mounting base 11 is provided with an external thread on its outer periphery, and the gas cylinder cover 20 is provided with an internal thread that is screwed into the external thread. However, using a threaded method requires a higher level of fit between the locking switch 30 and the gas cylinder cover 20.

[0035] In other embodiments, the locking element can be disposed on the pin of the gas cylinder cover 20, the end of the locking switch 30 extends into the gas cylinder cover 20, the locking element is a pin hole that cooperates with the pin, and the return spring 40 drives the locking switch 30 to move laterally so that the pin hole is sleeved on the pin.

[0036] In other embodiments, the drive unit includes a motor and a control panel. The control panel is disposed on the surface of the sparkling water machine body 10. The motor abuts against the locking switch 30. When the user touches the control panel, the motor can be driven to move the locking switch 30.

[0037] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
