[0003] For example, the Chinese patent with the announcement number CN218501255U discloses a self-sealing latex balloon with a pull-wire, which includes a balloon body that can be used to inflate and expand, the balloon body is provided with a spherical body and an air nozzle, the spherical body can be expanded and expanded by inflating the air nozzle, and a self-sealing plug with a pull-wire is provided, the self-sealing plug with a pull-wire is also provided with a sealing head and a pull-wire, the pull-wire and the sealing head are connected to each other, the sealing head is placed inside the spherical body, the pull-wire passes through the air nozzle and is exposed to the balloon body, when the balloon body is inflated, the pull-wire can be pulled to make the sealing head plug into the air nozzle to prevent the balloon body from leaking. The embodiment of the present invention provides a self-sealing latex balloon with a pull-wire, which can achieve rapid sealing of the latex balloon after inflation by arranging a sealing head for sealing inside the latex balloon, and arranging a pull-wire on the sealing head to make the position of the sealing head controllable, which is suitable for quickly injecting air and other gases and water and other liquids into the latex balloon, and can achieve the effect of sealing by pulling after filling, and can seal by itself without tying a knot.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: most of the latex balloons are inflated by an air pump, so when the user inflates the latex balloon, in order to prevent the balloon from leaking, the user needs to pinch the air inlet with his hand to inflate it. When a large number of balloons are needed for festivals, the user needs to pinch the air inlet with his hand for a long time to prevent the balloon from leaking. Because of the long-term pinching of the air inlet, the user's fatigue increases, which is not conducive to use. In view of this, we propose a latex balloon. Utility Model Content
