Description

Technical Field

[0001] The utility model relates to the technical field of balloon inflation nozzles, in particular to a balloon inflation nozzle with adjustable air deflation. Background Art

[0002] The main materials for floating balloons are latex, rubber, plastic, and aluminum foil. Latex balloons are widely used because of their high strength, high elasticity, uniform thickness, and long inflation duration. Large tethered or floating balloons can use complex electronic mechanical devices to control the ascent height and duration of flight by reducing the counterweight or changing the inflation volume. Small balloons are generally not controlled due to cost constraints. The ascent height and duration of flight are determined by the balloon's material, quality, weight, and inflation volume. Once released, they are basically uncontrollable. Tethered balloons can cause unpredictable consequences if accidentally launched. They can be used for commercial promotions, with advertising content printed on the balloons as needed. The existing technology has the following problems:

[0003] Existing latex balloons have excellent performance and are widely used. However, the time a floating balloon stays in the air is related to the quality, weight and inflation volume of the balloon, and has a high degree of dispersion, ranging from 1 to 2 hours to more than 12 hours. Tethered balloons are large in size, and if accidentally launched, they rise to a high altitude and stay in the air for a long time, which poses a greater risk. The cost of using complex electronic mechanical devices to control them is too high. At the same time, commercial activities flying balloons for advertising require pre-customized special balloons with printed advertisements, which have a long supply cycle and are expensive. The remaining balloons cannot change the prescribed advertising content. Utility Model Content

[0004] The utility model provides a balloon inflation nozzle with adjustable air deflation to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A balloon inflation nozzle with adjustable deflation comprises an inflation tube, a conical channel fixedly installed in the middle of the inner ring of the inflation tube, the conical channel having an air vent extending up and down, the inner cavity of the conical channel being provided with a one-way valve core, the bottom end of the one-way valve core extending through to the bottom of the conical channel and being provided with a rubber sealing gasket, a sealing plug being clamped at the bottom of the inner ring of the inflation tube, the bottom end of the sealing plug being fixedly connected to a suspension tether, and the bottom end of the suspension tether being fixedly connected to a counterweight.

[0007] A further improvement of the technical solution of the present utility model is that: when the inflation tube is inflated, an inflation transition plug is clamped at the bottom of the inner ring, and a conventional helium cylinder inflation nozzle is provided through the inner ring of the inflation transition plug, and the top end of the conventional helium cylinder inflation nozzle is located below the one-way valve core.

[0008] A further improvement of the technical solution of the present invention is that a storage wheel is provided above the inner cavity of the inflation tube, and an outer wall of the storage wheel is provided with advertising paper, which can be replaced at any time.

[0009] A further improvement of the technical solution of the present utility model is that the sealing plug is made of rubber material to improve the stability of being inserted into the bottom end of the inflation tube.

[0010] Due to the adoption of the above technical solution, the present invention has achieved the following technical advancements compared to the prior art:

[0011] 1. The utility model provides a balloon inflation nozzle with adjustable deflation. Through the mutual cooperation among the inflation tube, one-way valve core, sealing plug, suspension tether, and counterweight block, the inconsistency of the balloon's airborne time is effectively reduced, the launch height and airborne time of the airborne balloon are limited, and the airborne time range can be adjusted as needed. It is used to limit the airborne time of large tethered balloons when they are accidentally launched, reducing the impact of the balloon to an acceptable range.

[0012] 2. The utility model provides a balloon inflation nozzle with adjustable deflation. Through the cooperation between the inflation tube and the storage wheel, the inner cavity of the inflation tube can be built-in with advertising. The advertising content can be changed at will, thereby improving the advertising value.

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] like Figure 1 、 Figure 2As shown, the utility model provides a balloon inflation nozzle with adjustable deflation, comprising an inflation tube 1, a tapered channel 11 fixedly mounted in the middle of the inner ring of the inflation tube 1, the tapered channel 11 having an air vent 12 extending vertically therethrough, a one-way valve core 3 provided in the inner cavity of the tapered channel 11, the bottom end of the one-way valve core 3 extending through the bottom of the tapered channel 11 and provided with a rubber sealing gasket, a sealing plug 4 clamped at the bottom of the inner ring of the inflation tube 1, a suspension tether 5 fixedly connected to the bottom end of the suspension tether 5, a counterweight 6 fixedly connected to the bottom end of the sealing plug 4, and rubber material being used to improve the stability of the sealing plug 4 when clamped into the bottom end of the inflation tube 1;

[0018] After the balloon is released, the air begins to deflate at a pre-set rate until the balloon's buoyancy becomes less than its weight and the balloon begins to fall to the ground.

[0019] like Figure 1 、 Figure 2 As shown, when the inflation tube 1 is inflated, an inflation transition plug 7 is clamped at the bottom of the inner ring. A conventional helium cylinder inflation nozzle 8 is provided through the inner ring of the inflation transition plug 7. The top of the conventional helium cylinder inflation nozzle 8 is located below the one-way valve core 3. A storage wheel 2 is provided above the inner cavity of the inflation tube 1. Advertising paper is provided on the outer wall of the storage wheel 2 and can be replaced at any time. The inflation tube 1 is made of transparent plastic material, which makes it easy to view the advertising content on the storage wheel 2.

[0020] The tethered balloon is normally prevented from taking off by the tension of the main tether. When the main tether accidentally falls off or breaks, the suspension tether 5 is stretched and stressed, and the sealing plug 4 at the bottom end of the inflation tube 1 falls off. The balloon immediately begins to deflate and can float down in a short time. The storage wheel 2 is used for promotional advertising, and the content of the promotional advertising can be changed at will, which is convenient to use. A reward-based recycling method is adopted to maximize the recovery and centralized treatment of the fallen balloons, solving the environmental pollution problem caused by the release of balloons.

[0021] The working principle of the deflation-adjustable balloon inflation nozzle will be described in detail below.

[0022] like Figure 1-2As shown, the inflation tube 1 is a pipe for inflation and deflation and a mounting bracket for the one-way valve core 3. The one-way valve core 3 is closed under normal circumstances. When the balloon is inflated, the inflation pressure is greater than the internal pressure of the balloon, the one-way valve core 3 opens, and helium enters the balloon; after the inflation is completed, the one-way valve core 3 returns to its original position, and the one-way valve core 3 cannot be completely closed, and the gas in the balloon begins to deflate at a designed rate. After covering the sealing plug 4 at the bottom end of the inflation tube 1, the bottom end of the inflation tube 1 can be completely sealed, and the helium in the balloon will no longer deflate. When the air-floating balloon is released, due to the inflation tube 1 and the mounting bracket, the one-way valve core 3 opens, and the helium in the balloon will no longer deflate. The weight of the weight block 6 is greater than the buoyancy of the balloon, so the balloon will not accidentally rise into the air. The sealing plug 4 and the counterweight block 6 at the bottom of the inflation tube 1 must be removed before the balloon can be released. After the balloon is released, it begins to deflate at a pre-designed rate until the buoyancy of the balloon is less than the weight of the balloon, and it begins to fall until it hits the ground. The tethered balloon is normally prevented from rising into the air by the tension of the main tether. When the main tether accidentally falls off or breaks, the suspension tether 5 is stretched and stressed, and the sealing plug 4 at the bottom of the inflation tube 1 can fall off, and the balloon immediately begins to deflate and can float down in a short time.

[0023] While the present invention has been generally described above, it is readily apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are intended to be within the scope of protection of the present invention.
