DETAILED DESCRIPTION OF THE INVENTION

The detailed implementation of the present invention will be given below, and the technical solution of the present invention will be further described in combination with the drawings, but the present invention is not limited to these embodiments.

The present invention aims to improve the existing balloon with lights and solve the technical problems of inconvenient use and a short service life, so as to improve the manipulation performance of the balloon with lights and prolong its service life.

As shown in FIGS. 1-4, a pneumatically switched balloon light of the present invention comprises a balloon body 10, a battery case 20, a shield body 30, a valve cover 40 and an insulating piece 50.

The balloon body 10 is a spherical structure made of a latex material. The balloon body 10 has an air guide portion 11 in which an air inlet 12 is made. The battery case 20 is located in the balloon body 10, two adjacent batteries 21 are provided in the battery case 20, and one end of the battery case 20 towards the inside of the balloon body 20 is mounted with an LED light 22 which is electrically connected with the batteries 21. The shield body 30 is located in the air guide portion 11, the shield body 30 and the air guide portion 11 are relatively fixed and sealed there between, and one end of the shield body 30 is removably connected with the battery case 20 while the other end has a breather hole 31 which communicates with the interior of the balloon body 10. The valve cover 40 is arranged in the shield body 30 and separated from the breather hole 31. One end of the insulting piece 50 is fixedly connected with the valve cover 40, and the other end is inserted between the batteries 21.

In operation, the balloon body 10 is filled with air through the air inlet 12. When the balloon body 10 inflates and the air pressure in the balloon body 10 is greater than the atmospheric pressure outside, since the valve cover 40 is separated from the shield body 30, under the action of the air pressure in the balloon body 10, the valve cover 40 and the insulating piece 50 move synchronously within the shield body 30, until the valve cover 40 blocks up the breather hole 31, the insulating piece 50 disengages itself from the batteries 21, and the batteries 21 are electrically connected with the LED light 22, thereby enabling the LED light 22 to emit light inside the balloon body 10.

Of course, the balloon body 10 can also emit light without sufficient gas. When a small amount of gas is filled into the balloon body 10, the air pressure inside the balloon body 10 can be instantaneously increased by tapping the balloon body 10, so that the gas inside the balloon body 10 flows towards the air inlet 12, and during the flow, it will drive the valve cover 14 to move and block up the breather hole 31, which can also enable the LED light 22 to emit light.

To discharge the air out of the balloon body 10, press the valve cover 40 until it is away from the shield body 30. While air discharge of the balloon body 10 is achieved, the insulating piece 50 is inserted between the batteries 21 to turn off the LED light 22.

In the present invention, the valve cover 40 and the insulating piece 50 move in the shield body 30, which not only can achieve the air intake and discharge of the balloon body 10, but also control the on and off of the LED light 22. The balloon light is convenient to use without removing the battery case 20, and has a more stable structure and a longer service life.

It should be noted that in this structure, the breather hole 31 is blocked up by the valve cover 40, so the air guide portion 11 does not have to be knotted when the inflation of the balloon body 10 is done, which makes inflation and deflation convenient and efficient.

According to the present invention, the foregoing structure is further improved and refined.

As shown in FIGS. 2-4, an insertion-connection block 41 is provided inside the valve cover 40, and the insertion-connection block 41 is made with a slot 42 for inserting and fixing the insulating piece 50.

The insulating piece 50 is inserted and connected with the insertion-connection block 41 to fix the insulating piece 50 and the valve cover 40 together, which makes it easy to assemble and disassemble the insulating piece 50 and the valve cover 40, and convenient to replace the insulating piece 50.

As shown in FIGS. 2-4, the valve cover 40 has a tapered portion 43 at one end close to the air inlet 31, a tapered socket 32 is correspondingly provided in the shield body 30, the breather hole 31 is co-axial and communicates with the tapered socket 32, and the tapered portion 43 is pressed against the surface of the tapered socket 32.

The contact portion of the valve cover 40 and the shield body 30 is configured into a tapered structure, so that the valve cover 40 is in closer contact with the shield body 30, thereby improving the stability of the valve cover 40 when it comes into contact with the shield body 30, and also improving the seal between the valve cover 40 and the shield body 30 which prevents the balloon body 10 from leaking.

As shown in FIGS. 2-4, the outer surface of the battery case 20 is laterally provided with a retaining block 23, and the inner surface of the shield body 30 is correspondingly made with a retaining groove 33, such that the retaining block 32 is embedded in the retaining groove 33.

The fit of the retaining block 23 and the retaining groove 33 allows the battery case 20 and the shield body 30 to be connected and fixed together, so that the battery case 20 and the shield body 30 are stable and therefore do not easily move relative to each other.

Of course, when a relatively large force is applied to the battery case 20 and the shield body 30 respectively in an opposite direction, the battery case 20 and the shield body 30 can also be separated, which makes it is quite convenient to assemble and easy to disassemble the battery case 20 and the shield body 30.

As shown in FIGS. 2-4, the outer surface of the battery case 20 is laterally provided with a stop block 24 such that when the retaining block 23 is in the retaining groove 33, one end of the shield body 30 rests against the stop block 24.

In this embodiment, to assemble the battery case 20 and the shield body 30, it is necessary to push the battery case 20 and the shield body 30 with a large force so as to push the battery case 20 into the shield body 30 and the retaining block 23 into the retaining groove 33. However, if the force is too large, the retaining block 23, which has already been pushed into the retaining groove 33, will leave the retaining groove 33 under the action of inertia. By providing the stop block 24, the shield body 30 rests against the stop block 24 when the retaining block 23 enters the retaining groove 33, so that the retaining block 23 always stays in the retaining groove 33, which improves the assembly efficiency.

In addition, the fit of the retaining block 23 and the retaining groove 33 fixedly connects the battery case 20 and the shield body 30 together which do not easily move relative to each other. However, when the air has to be discharged out of the balloon body 10, if the valve cover 40 is pressed by hand, said hand will also touch the shield body 30. When the force is too large, it will also cause the retaining block 23 to leave the retaining groove 33, resulting in the shield body 30 and the battery case 20 moving relative to each other.

As shown in FIG. 3 and FIG. 4, the outer surface of the battery case 20 is made with an axially extending breather groove 25, the breather groove 25 communicates with the balloon body 10 and the shield body 30 respectively, and the breather groove 25 extends through the retaining block 23 and the stop block 24.

By making the breather groove 25, the communication among the breather hole 31, the breather groove 25, and the inside of the balloon body 10 is achieved, and the normal air intake and discharge of the balloon body 10 are ensured.

As shown in FIG. 3 and FIG. 4, the entire battery case 20 is assembled by inserting and connecting the upper case body 26 and the lower case body 27 together, which is convenient to assemble. A mounting shield 27a is permanently provided on the inner surface of the lower case body 27, and the batteries 21 are located in the mounting shield 27a. A receiving opening 27b is made in one side of the mounting shield 27a, and an insertion hole 28 corresponding to the receiving opening 27b is made in one end of the battery case 20, and the insertion hole 28 is enclosed by gaps in the upper case body 26 and the lower case body 27. The insulating piece 50 is located in the insertion hole 28 and the receiving opening 27b and moves in the insertion hole 28 and the receiving opening 27b.

The mounting shield 27a provides a mounting area for the batteries 21, while avoiding the shaking of the batteries 21, improving the stability of the batteries 21. The insulating piece 50 is located in the insertion hole 28 and the receiving opening 27b, so that the insulating piece 50 will not deviate from its normal movement path, and the movement accuracy is higher, which ensures that the insulating piece 50 can be correctly inserted between the batteries 21.

As shown in FIG. 3 and FIG. 4, one end of the battery case 20 is provided with a mounting holder 29, the inside of which is made with a mounting groove 29a, the mounting holder 29 is formed by the semi-cylindrical structures fixedly connected with the ends of the upper case body 26 and the lower case body 27, the LED light 22 is disposed on a light base, the light base is locked in the mounting groove 29a and the LED light 22 passes through the mounting holder 29.

The LED light 22 is locked in the mounting groove 29a, which provides good stability. During assembly of the battery case 20, the LED light 22 is placed in one half of the mounting groove 29a first, and then the upper case body 26 and the lower case body 27 are put together to fix the LED light 22, which makes the assembly of the LED light 22 and the battery case 22 very simple and convenient.

As shown in FIG. 1 and FIG. 2, a sealing sleeve 60 is provided outside the air guide portion 11, the air guide portion 11 is located between the shield body 30 and the sealing sleeve 60, the sealing sleeve 60 is removably connected with the shield body 30, and the air guide portion 11 is pressed against the sealing sleeve and the shield body 30 respectively. Preferably, the outer surface of the shield body 30 is circumferentially provided with a locking block 34, and the inner surface of the sealing sleeve 60 is circumferentially made with a locking groove 61, such that the locking block 34 is in the locking groove 61 and the balloon body 10 is pressed against the locking block 34 and the locking groove 61 respectively.

The air guide portion 11 of the balloon body 10 is located between the sealing sleeve 60 and the shield body 30 and clamped by the two to provide a good sealing between the shield body 30 and the balloon body 10 so that the balloon body 10 will not leak. The sealing sleeve 60 and the shield body 30 are engaged with each other by means of the locking block 34 and the locking groove 61, so that the sealing sleeve 60 is easily disassembled from the balloon body 10 and the shield body 30.

The operating principle of the present invention is as follows:

In the initial state, the valve cover 40 is away from the air inlet 31. The balloon body 10 is filled with air by blowing or with an inflating tool. When the balloon body 10 is inflated to a predetermined size and the air pressure in the balloon body 10 is greater than the atmospheric pressure outside, under the action of the air pressure in the balloon body 10, the valve cover 40 and the insulating piece 50 move synchronously within the shield body 30, until the valve cover 40 blocks up the breather hole 31, the insulating piece 50 disengages itself from the batteries 21, and the batteries 21 are electrically connected with the LED light 22, thereby enabling the LED light 22 to emit light inside the balloon body 10.

When the LED light 22 needs to be turned off and the air needs to be discharged out of the balloon body 10, the valve cover 40 is pressed away from the shield body 30, and the breather hole 31 is opened, which not only enables the air to be discharged out of the balloon body 10, also enables the insulating piece 50 to be inserted between the two batteries 21, thereby turning off the LED light 22. In such a way, the balloon light can be repeatedly used.

The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the technical field of the present invention can make various modifications or additions to the specific embodiments described or adopt similar alternates, without departing from the spirit of the present invention or going beyond the scope as defined by the attached claims.
