AUTOMATIC SELF-SEALING BALLOON

Description

TECHNICAL FIELD

The present application relates to a technical field of balloons, in particular to an automatic self-sealing balloon.

BACKGROUND

Water balloons are one of the children's favourite toys. After filling balloons with water, children can play games with water balloons, throwing water balloons to each other. Water balloons are made from rubber. Children put the balloons on the faucet for filling water and manually seal the balloons after the balloons are full of water.

However, the following problems may exist for younger children when manually sealing balloons:

Children's arm strength is not sufficient to quickly and efficiently tie the balloons tightly;

Due to children's improper operation in sealing the balloons, water may splash out of the balloons and clothes may get wet.

The technical solution adopted by the present application for the technical problems is:

An automatic self-sealing balloon, includes a balloon body and a water injection port arranged on the balloon body. A cavity is formed inside the balloon body, and the water injection port communicates the cavity with the external environment. A sealing member is provided in the cavity, and the sealing member is made from materials with a density less than water. The sealing member's peripheral contour is greater than the water injection port's inner contour.

As a further improvement of the above technical solution, the sealing member is of a spherical structure and the water injection port is of a columnar structure.

As a further improvement of the above technical solution, the sealing member is made from foam materials.

As a further improvement of the above technical solution, the sealing member is made from plastic materials.

As a further improvement of the above technical solution, the balloon body is made from rubber materials.

As a further improvement of the above technical solution, the balloon body and the water injection port are integral.

As a further improvement of the above technical solution, a ratio of the water injection port's cross-sectional diameter to the sealing member's diameter is 1:1.5.

As a further improvement of the above technical solution, patterns are printed on the outer surface of the balloon body.

The beneficial effects achieved by the present application are:

The present application provides an automatic self-sealing balloon, which includes a balloon body, a sealing member arranged in the balloon body's cavity, and a water injection port arranged on the balloon body. The sealing member is made from materials of less dense than water, and further the sealing member's peripheral contour is greater than the water injection port's inner contour. When the balloon body's cavity is filled with water or inflated with gas to the full extent, the sealing member blocks the water injection port to realize automatic self-sealing function. The balloon of the present application is specially suitable for children in that it is easy for a child to seal the water injection port to prevent water from splashing out when playing.

DESCRIPTION OF EMBODIMENTS

The following will clearly and completely describe the concept, specific structure and technical effects of the present application in combination with the embodiments and figures, so as to fully understand the purpose, characteristics and effects of the present application. Obviously, the described embodiments are only one part of the embodiments of the present application, rather than all of them. Based on the embodiments of the present application, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present application. In addition, all the connection relationships involved in the present application do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the present application can be combined interchangeably without conflicting with each other.

Referring to FIGS. 1 and 2, the present application provides an automatic self-sealing balloon with a sealing member 3 arranged in the cavity 10. When the cavity 10 of the balloon body 1 is filled with water or inflated with gas to the full extent, the sealing member 3 blocks the water injection port 2 to realize automatic self-sealing function due to the sealing member 3 made from materials of a less dense than water and the sealing member's peripheral contour greater than the water injection port's inner contour. The balloon of the present application is specially suitable for children in that it is easy for a child to seal the water injection port to prevent water from splashing out when playing.

In particular, the present application provides an automatic self-sealing water balloon, including balloon body 1 and a water injection port 2 arranged on the balloon body. A cavity 10 is formed inside the balloon body 1, and the water injection port 2 communicates the cavity 10 with the external environment. Users fill water into the cavity 10 of the balloon body 1 through the water injection port 2.

In this embodiment, a sealing member 3 is provided in the cavity 10, and the sealing member 3 is made from materials of less dense than water. When the cavity 10 of the balloon body 1 is filled with enough water, the sealing member 3 floats on the water.

Furthermore, the peripheral contour of the sealing member 3 is greater than the inner contour of the water injection port 2. It can be understood that the sealing member 3 is always floating on the water in the process of filling water into the cavity 10. Once the cavity 10 is filled with water to the full extent, the sealing member 3 blocks the water injection port 2 and automatically seals the water injection port 2. Because the size of the sealing member 3 is larger than that of the water injection port 2, the sealing member 3 fails to move out of the balloon body 1 along the water injection port 2 to the external environment, as a result of which the sealing member 3 keeps the water injection port 2 in a blocked status.

In this embodiment, the ratio of the cross-sectional diameter of the water injection port 2 to the diameter of the sealing member 3 is 1:1.5.

In this embodiment, the water injection port 2 is of a columnar structure. Users fill water into the cavity by attaching the columnar structure to a faucet. Correspondingly, the sealing member 3 is of a spherical structure. When the cavity 10 is filled with enough water, the sealing member 3 blocks the columnar structure to realize automatic self-sealing function.

In this embodiment, the sealing member 3 is made from foam materials. In another embodiment, the sealing member 3 is made from plastic materials.

In this embodiment, the balloon body 1 is made from rubber materials. Furthermore, the balloon body 1 and the water injection port 2 are integral.

In this embodiment, patterns are printed on the outer surface of the balloon body 1. In particular, the patterns can be customized as cartoon characters, expressions or animal patterns. With simple interesting, colorful and cute patterns printed on surface, the balloon can easily attract the children's attention.

The present application provides a method of use of the automatic self-sealing balloon as follows:

Keep the water injection port 2 upwards and connect the water injection port 2 with a water filling device to fill water into the cavity 10. The sealing member 3 moves towards the water injection port 2 subject to buoyancy force and pressure, and the water injection port 2 is blocked by the sealing member 3 to realize the function of automatic self-sealing and prevent the leakage of liquid.

In addition, the automatic self-sealing balloon of the present application is also applicable in the scenario of gas inflation. The water injection port 2 becomes an inflation inlet, and gas is inflated into the cavity 10 through the inflation inlet. When the cavity 10 is inflated with gas to the full extent, put the balloon body 1 upside down and the sealing member 3 will fall to the inflation inlet subject to gravity, and then the inflation inlet is automatically blocked.

It can be understood that, under the guidance of the above embodiments, those skilled in the art can combine various implementation methods in the above embodiments to obtain a technical solution of multiple implementation methods.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application are all within the protection scope of the present application.
