Balloon nozzle

Abstract

This invention provides a nozzle for balloons, comprising a sleeve portion exposed on the outside of a balloon's neck, an expansion portion located inside the neck, and a plurality of openings. A portion of the neck is airtightly attached to the expansion portion. When gas with sufficient pressure is injected through an air hole in the sleeve portion, the balloon's neck is stretched apart by the gas pressure, separating it from the expansion portion, allowing gas to be filled into an inflation space defined by the balloon, causing the balloon to inflate. When gas with insufficient pressure is injected through the air holes, the balloon's neck remains airtightly attached to the expansion portion due to elasticity and atmospheric pressure, preventing air leakage from the inflation space and further maintaining the balloon in an inflated state.

Description

Technical Field

[0001] The invention relates to a nozzle for a balloon, in particular to a nozzle which is easy to inject air into the balloon and prevents the gas in the balloon from leaking out of the balloon when the blowing stops. Background Art

[0002] Generally, a balloon is blown up by injecting gas into the inflation space of the balloon from the open end of the balloon's neck, so that the gas drives an expansion part of the balloon to expand, and in order to keep the balloon in an inflated state, the neck of the balloon needs to be tied to prevent the gas from leaking out of the balloon, so that the balloon can maintain an inflated state. However, such an operation is quite time-consuming, and the traditional method of blowing a balloon cannot effectively perform continuous automatic inflation through mechanized control, so there is room for improvement. Summary of the invention

[0003] The purpose of the present invention is to provide a balloon nozzle to solve the above-mentioned technical problems existing in the prior art.

[0004] To solve this problem, the present invention provides an air nozzle for a balloon, the air nozzle comprising a sleeve portion, the sleeve portion comprising an inner end and an outer end separated from each other, the sleeve portion further comprising an air hole extending from the outer end to the inner end, the air nozzle further comprising an expansion portion separated from the sleeve portion and a connecting portion connected between the expansion portion and the inner end of the sleeve portion, an open mouth connected to the air hole is formed on the connecting portion, the expansion portion comprises an outer peripheral edge, the air nozzle is suitable for combining with a neck of a balloon, the expansion portion is accommodated in the neck of the balloon and stretches the corresponding neck, the outer end of the sleeve portion is located on the outside of the neck, the open mouth is covered in the neck, when gas without sufficient pressure is poured into the air hole, an inflation space defined inside the balloon is not connected to the air hole, and when gas with sufficient pressure is poured into the air hole, the inflation space is connected to the air hole, so that the gas enters the inflation space.

[0005] The sleeve connection part further comprises an embedding groove formed on the outer peripheral surface and between the outer end and the inner end, and the embedding groove is suitable for embedding with an open end comprised by the end of the neck of the balloon.

[0006] The balloon nozzle, the sleeve connection part also includes a coupling groove formed on the outer peripheral surface and between the embedding groove and the outer end, the coupling groove is suitable for providing a plurality of jackets included in a clamping plate for detachable coupling.

[0007] The air nozzle for the balloon, wherein the expansion portion includes a conical first surface and a second surface, and the expansion portion also includes an outer peripheral edge formed between the first and second surfaces, and the outer peripheral edge is suitable for expanding the neck of the balloon. When gas with insufficient pressure is poured into the air hole, the first surface and the neck provide the neck of the balloon for contact. When gas with sufficient pressure is poured into the air hole, the neck of the balloon is separated from the first surface and the neck, so that the air hole is connected to the inflation space.

[0008] The first surface of the expansion portion is designed to be conical, so that when not inflated, a larger portion of the balloon's neck is airtightly attached to the first surface (compared to a flat surface), providing optimal airtightness and allowing the balloon to last longer after being inflated.

[0009] The opening is located inside the outer periphery and between the first surface and the inner end.

[0010] The sleeve connection part further comprises a flange formed on the outer periphery and between the embedding groove and the inner end, and the flange is suitable for expanding the neck of the balloon.

[0011] The flange expands the neck of the balloon, so that even if the neck expands due to inflation during the inflation of the balloon, the expanded range of the flange will not be affected, and the balloon can be further prevented from being separated from the air nozzle during the inflation process.

[0012] Compared with the prior art, the present invention has the following beneficial effects: the air nozzle of the present invention provides a function of facilitating the inflation of the balloon, and after the balloon is inflated, there is no need to tie the neck or tie a knot in the neck to prevent the gas filled into the inflation space of the balloon from leaking out, which can speed up the inflation of the balloon, and can be inflated continuously and quickly through the air nozzle in conjunction with mechanical automation.

[0013] The present invention will be more clearly understood with reference to the detailed description of illustrative embodiments of the present invention described in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] All drawings are only for the purpose of explaining the basic teachings of the present invention. The numbers, positions, relationships, and dimensions of the components constituting the preferred embodiments are described in the drawings. After reading and understanding the teachings of the present invention, it is within the skill of the industry to implement related changes. In addition, after reading and understanding the teachings of the present invention, it is also within the skill of the industry to change the precise dimensions and dimensional ratios to meet specific force, weight, strength, and similar requirements.

[0023] The air nozzle of the present invention is an air nozzle 10 that can be installed in a rubber balloon to serve as an inflation medium and prevent gas from leaking out of the balloon after inflation. Referring to Figures 1 and 2, the air nozzle 10 includes a sleeve portion 20, the sleeve portion 20 includes an inner end 22 and an outer end 24 that are separated from each other, the sleeve portion 20 also includes an air hole 26 extending from the outer end 24 to the inner end 22, the sleeve portion 20 also includes an annular embedding groove 28 formed on the outer periphery and between the inner and outer ends 22 and 24, and a coupling groove 30 formed on the outer periphery and between the embedding groove 28 and the outer end 24. The sleeve portion 20 also includes a flange 31 formed on the outer periphery and between the embedding groove 28 and the inner end 22.

[0024] The air nozzle 10 further includes an expansion portion 32 separated from the sleeve portion 20 and a connecting portion 40 connected between the expansion portion 32 and the sleeve portion 20. The expansion portion 32 includes a first surface 34 and a second surface 36 of a cone shape. The expansion portion 32 further includes an outer peripheral edge 38 extending between the outer ends of the first and second surfaces 34 and 36. The connecting portion 40 is composed of a plurality of connecting strips extending between the first surface 34 of the expansion portion 32 and the inner end 22 of the sleeve portion 20 and spaced inside the outer peripheral edge 38, so that a plurality of openings 42 communicating with the air hole 26 are defined between the sleeve portion 20 and the expansion portion 32, see Figure 2 As shown, the plurality of openings 42 are substantially located inside the outer periphery 38 and between the first surface 34 and the inner end 22 .

[0025] See also Figure 3 As shown, the air nozzle 10 is installed on a neck 48 of a balloon 44, and the balloon 44 includes an expansion portion 46 extending from the neck 48 and larger than the neck 48. In addition, the neck 48 includes an open end 50 at the end, and the interior of the balloon 44 defines an inflation space 52. It should be noted that the outer contour of the expansion portion 32 is larger than the size of the neck 48 of the balloon 44, and the inner annular wall size of the embedding groove 28 is also larger than the neck 48 of the balloon 44.

[0026] The air nozzle 10 is inserted from the open end 50 of the balloon 44, the expansion portion 32 and the flange 31 of the air nozzle 10 are located in the neck 48, and the outer end 24 of the sleeve portion 20 and the coupling groove 30 are located outside the neck 48 of the balloon 44, the open end 50 of the balloon 44 is engaged with the embedding groove 28, and the expansion portion 32 and the flange 31 expand the neck 48 of the balloon 44 (such as Figure 3 As shown, the portion of the neck 48 that is stretched open by the expansion portion 32 forms an airtight fit against the outer peripheral edge 38 and the first surface 34 of the expansion portion 32, so that the inflation space 52 of the balloon 44 is not connected to the open mouth 42 and the air hole 26, and further, the air inside the inflation space 52 cannot be discharged.

[0027] When the balloon 44 is to be inflated, an inflating device 58 is placed in close contact with the air hole 26 of the air nozzle 10, so that the pressure generated by the gas output from the inflating device 58 is sufficient to counteract the elasticity of the neck 48 of the balloon 44 and the atmospheric pressure, so that the gas of the inflating device 58 pushes the neck 48 of the balloon 44 from each opening 42, so that the inner surface of the neck 48 is separated from the first surface 34 and the outer peripheral edge 38 of the expansion portion 32 to form a gap allowing gas to pass through (such as Figure 4As shown in FIG. 5 , the gas outputted from the inflating device 58 can enter the inflation space 52 of the balloon 44, further expanding the expansion portion 46 of the balloon 44. In addition, when the inflating device 58 stops operating, the neck 48 of the balloon 44 again abuts against the outer peripheral edge 38 and the first surface 34 of the expansion portion 32 due to elasticity and atmospheric pressure, and the gas further inflated into the inflation space 52 inside the balloon 44 cannot leak out (as shown in FIG. 5 ). Figure 5 As shown), the balloon 44 can remain in an inflated state.

[0028] It is worth mentioning that during the inflation of the balloon 44, even if the neck 48 of the portion adjacent to the connection portion 40 is slightly expanded by the pressure of the injected gas, the flange 31 expands the corresponding neck 48 further (e.g., Figure 4 As shown), the air nozzle 10 is not easily separated from the neck 48 of the balloon 44 during the inflation process of the balloon 44, thereby ensuring that the inflation process is safer and smoother.

[0029] Referring to Figures 6 and 7, the coupling groove 30 of the air nozzle 10 is used to couple with a clamp 54, and the clamp 54 includes a plurality of clamp sleeves 56 spaced apart from each other at an appropriate distance. The clamp 54 can clamp a plurality of air nozzles 10 and the balloons 44 coupled to the air nozzles 10 at one time, so that the plurality of balloons 44 can be quickly and continuously inflated in a cycle using an inflation device.

[0030] The air nozzle 10 of the present invention provides a function of facilitating the inflation of the balloon 44, and after the balloon 44 is inflated, there is no need to additionally tie the neck 48 or tie a knot in the neck 48 to prevent the gas in the inflation space 52 of the balloon 44 from leaking out, which can speed up the inflation of the balloon 44 and enable continuous and rapid inflation through the air nozzle in conjunction with mechanical automation.

[0031] In addition, the first surface 34 of the expansion portion 32 is designed to be conical, so that when not inflated, a larger portion of the neck 48 of the balloon 44 is airtightly attached to the first surface 34 (compared to a plane), which can provide an optimal airtight effect and allow the balloon 44 to last longer after being inflated.

[0032] The flange 31 expands the neck 48 of the balloon 44, so that even if the neck 48 expands due to inflation during the inflation of the balloon 44, the expanded range of the flange 31 will not be affected, and the balloon 44 can be further prevented from being separated from the air nozzle 10 during the inflation process.

[0033] The basic teaching of the present invention has been described, and many extensions and changes will be obvious to those with ordinary skills in the art. For example, even if the surface of the sleeve portion 20 of the air nozzle 10 of the present invention does not have the embedding groove 28, the embedding groove 28 of the sleeve portion 20 can still provide a stable sleeve for the open end 50 of the balloon 44, without hindering the stable sleeve positioning of the neck 48 of the balloon 44 around the sleeve portion 20 of the air nozzle 10. Alternatively, the first surface 34 and the second surface 36 of the expansion portion 32 can be flat. In this state, although the portion of the neck 48 of the balloon 44 that is airtightly attached to the first surface 34 when not inflated is less than that of the conical first surface 34, it still has a sufficient airtight effect. Alternatively, there can be only one opening 42, so that the connecting portion 40 can be tubular, and an opening 42 is provided in the tubular connecting portion, which can still achieve the same function.

[0034] The above description is only illustrative rather than restrictive of the present invention. Those skilled in the art will understand that many modifications, changes or equivalents may be made without departing from the spirit and scope defined by the claims, but all will fall within the scope of protection of the present invention.
