[0029] Embodiment 1:

[0030] like Figure 1-6 As shown, the utility model provides a handheld launching device, comprising a gas cylinder 1, a bottle stopper 2, a guide tube 3, an air charging valve 4 and a medium cylinder 5; the gas cylinder 1 is used to store gas, such as nitrogen; the gas cylinder 1 comprises a bottle neck 6; the bottle stopper 2 is threadedly connected in the bottle neck 6; the guide tube 3 is coaxially sleeved outside the bottle stopper 2, and the guide tube 3 can be deformed and can contact the bottle stopper 2; specifically, the guide tube 3 needs to have a certain elastic deformation ability, and can use a soft plastic material, such as flexible polyvinyl chloride or polyurethane;

[0031] The inflation valve 4 is installed on the top of the bottle stopper 2; the medium tube 5 is detachably connected to the end of the guide tube 3 away from the gas cylinder 1; specifically, the bottle stopper 2 is provided with an inflation hole (not shown in the figure) connected to the gas cylinder 1. The inflation valve 4 is inserted into the inflation hole of the bottle stopper 2 by rotating or pushing until it is fully installed to ensure a good fit. If necessary, a layer of sealant can be applied to the interface between the inflation valve and the bottle stopper to enhance the sealing effect. Select a sealant suitable for a high-pressure gas environment and ensure that it will not affect the normal use of the inflation valve and the bottle stopper. For example, the sealant can be Viton sealant. Viton is a common fluororubber sealing material with excellent high temperature resistance, chemical corrosion resistance and high pressure resistance, and is usually used for sealing high-pressure gas systems.

[0032] Specifically, the gas cylinder 1 is made of high-strength metal materials, such as stainless steel or aluminum alloy, to ensure that it can withstand gas without deformation or leakage; the bottle stopper 2 also needs to have high strength and pressure resistance, and can be threadedly connected to the neck 6 of the gas cylinder 1 to ensure airtightness. Polyetheretherketone can be used. At the same time, in order to avoid gas leakage before opening the bottle stopper, airtightness needs to be considered. A sealant for high-pressure gas environment can be used, and it will not produce an overly strong bonding effect, such as fluororubber sealant, which usually has excellent high temperature resistance and chemical corrosion resistance and is suitable for high-pressure gas environments. They usually have good elasticity and durability, and can provide reliable sealing effects under high-pressure conditions;

[0033] The medium cylinder 5 can be made of plastic material, such as polypropylene and polyethylene, to ensure the plasticity of the production process, easy processing and molding. If necessary, the plastic material can be made of a higher modified plastic to improve the strength and durability of the medium cylinder 5. In principle, the material of the medium cylinder 5 can be sufficient to meet the requirements of the medium cylinder 5 for compression resistance and crack resistance.

[0034] Among them, the inflation valve 4 is a one-way valve, and nitrogen can only be added to the gas cylinder 1 through the inflation valve 4. The one-way valve design can ensure that the gas can only flow in one direction to prevent the gas from leaking out of the gas cylinder 1; the one-way valve is easy to operate, and only needs to connect the inflation equipment to the valve and operate according to the instructions, without the need for additional complicated steps.

[0035] The principle and beneficial effects of the above technical solution:

[0036] During assembly, thin paper is glued to both ends of the medium tube 5 so that the emission medium can be confined within the medium tube 5. Then one end of the medium tube 5 is coaxially glued to the guide tube 3, and tape is wrapped around the outer walls of both to ensure that the connection between the medium tube 5 and the guide tube 3 is stable and reduce the risk of loosening or falling off.

[0037] During operation, the guide tube 3 connected with the medium cylinder 5 is put on the outside of the bottle stopper 2. Since the guide tube 3 can undergo elastic deformation, the gas cylinder 1 is held in one hand, and the guide tube 3 is held and squeezed with the other hand, so that the bottle stopper 2 can be driven to rotate by rotating the guide tube 3. When the bottle stopper 2 is separated from the bottleneck 6, the bottle stopper 2 loses the constraint of the bottleneck 6, so that the nitrogen in the gas cylinder 1 can rush out. The rushing gas generates a thrust on the bottle stopper 2, so that the bottle stopper 2 moves toward the medium cylinder 5.

[0038] When the cork 2 is pushed by the gas, it breaks through the thin paper at the end of the medium tube 5, and then the cork 2 continues to act on the emission medium in the medium tube 5, so that the emission medium in the medium tube 5 can be pushed out by the cork 2, thereby completing the emission of the emission medium.

[0039] For reference, the launch medium can be existing confetti, existing ribbons, existing rubber balls and other materials. The launch medium can be selected according to the specific situation. In principle, the above-mentioned launch medium can be loaded alone or mixed.

[0040] It is worth noting that after the gas cylinder 1 completes the launch of the launch medium, the bottle stopper 2 is threadedly connected to the bottle neck 6, so that the bottle neck 6 is in a sealed state, and then nitrogen is added to the gas cylinder 1 again through the one-way venting inflation valve 4 to complete the gas filling. Through the above method, another medium cylinder 5 is connected to the guide tube 3, and the guide tube 3 is sleeved outside the bottle stopper 2 to complete the filling. The filled device can meet the re-launching needs, so that in the application scenario of multiple launches, only the corresponding medium cylinder 5 is stored as a disposable consumable, which effectively avoids the tediousness of replacing the gas cylinder 1 and the guide tube 3.

[0041] Secondly, the device uses one gas cylinder 1 for multiple uses, and the device can adapt to various types of emission media as needed. This configuration is not only convenient for replacing the configuration of the medium cylinder 5, but also does not require replacement of multiple components in the device, thereby reducing the use of consumable parts, which is conducive to increasing the service life of the device and avoiding one-time use. At the same time, the use of a one-way ventilated inflation valve 4 can easily add nitrogen to the gas cylinder 1 again, making the entire filling process more convenient and efficient.

[0042] Embodiment 2:

[0043] This embodiment is based on the first embodiment. Figure 3-5 As shown, the device also includes a guide assembly; the guide assembly is used to connect the bottle stopper 2 and the guide tube 3, so that the movement of the bottle stopper 2 can be guided by the guide assembly; the guide assembly includes a rotating ring 7 and a guide block 8; a first annular groove 9 is opened on the peripheral side of the bottle neck 6, and the first annular groove 9 is not connected to the bottle neck 6; the first annular groove 9 is coaxial with the gas cylinder 1 to ensure that when the guide tube 3 is rotated, the inner wall of the guide tube 3 is prevented from colliding with the bottle stopper 2; the rotating ring 7 is coaxially rotatably connected in the first annular groove 9, and the cooperation of the first annular groove 9 and the rotating ring 7 ensures that the guide tube 3 connected to the rotating ring 7 is in a limited state to avoid the guide tube 3 from accidentally detaching; the bottom end of the guide tube 3 is coaxially fixedly connected to the rotating ring 7; a guide groove 10 is opened on the inner wall of the ring of the guide tube 3; the guide groove 10 penetrates along the radial direction of the guide tube 3 to the end of the guide tube 3 away from the gas cylinder 1; the guide block 8 is fixedly connected to the peripheral side of the bottle stopper 2; the guide block 8 is in sliding contact with the guide groove 10.

[0044] The principle and beneficial effects of the above technical solution:

[0045] During the specific implementation, the medium cylinder 5 is connected to the guide tube 3 by the above method, and then the guide tube 3 is rotated with one hand and the gas cylinder 1 is held with the other hand. Since the guide block 8 is slidably connected in the guide groove 10, when the guide tube 3 is rotated, the guide block 8 is driven to follow the rotation through the guide groove 10 on the guide tube 3, and then the guide block 8 can drive the bottle stopper 2 to rotate, so that the bottle stopper 2 is gradually rotated out of the bottleneck 6, and the bottle stopper 2 is pushed to move under the action of gas. During the movement, the guide block 8 slides in the guide groove 10, so as to guide the movement of the bottle stopper 2, ensuring that the bottle stopper 2 remains in a horizontal state and moves along the axial direction of the medium cylinder 5, thereby stably launching the launch medium.

[0046] During firing, the high-pressure gas in the gas cylinder 1 is emitted, thereby driving the stopper 2 to move, and at the same time, the guide block 8 fixedly connected to the side of the stopper 2 slides in the guide groove 10. The sliding design of the guide block 8 in the guide groove 10 effectively guides the movement of the stopper 2, so that the stopper 2 maintains a horizontal state and moves axially, thereby ensuring that the firing process of the firing medium is more stable and reliable; the design of the guide block 8 and the guide groove 10 enables the movement of the stopper 2 to be well guided, reduces the problems caused by swinging or inaccurate position adjustment, and enhances the reliability of the firing process.

[0047] When filling again, the bottle stopper 2 is slid into the guide tube 3 along the guide groove 10 under the action of the guide block 8, and can be re-threaded on the bottle neck 6. If necessary, fluororubber sealant can be used to enhance the sealing performance, and then nitrogen can be re-added to the gas storage cylinder 1 through the inflation valve 4.

[0048] Compared with the method of Example 1 in which the cork 2 is screwed out by holding and squeezing the guide tube 3, it is necessary to loosen the guide tube 3 appropriately after screwing out the cork 2 to avoid getting stuck in the cork 2 and ensure that the cork 2 can be pushed by the gas; however, in the present embodiment, there is no need to squeeze the guide tube 3. Under the action of the guide assembly, the cork 2 can be immediately pushed by the gas and move along the guide groove 10 after being screwed out of the bottleneck 6, and can respond in time.

[0049] In this embodiment, Figure 3 , 4 As shown, a sliding ring 11 is sleeved on the bottle stopper 2, specifically, the sliding ring 11 is sleeved on the bottle stopper 2 by a fixed connection; the sliding ring 11 is coaxial with the medium cylinder 5; specifically, the guide block 8 is fixedly connected to the circumference of the sliding ring 11; a balancing tube 12 is coaxially welded to the bottom side of the sliding ring 11; there is a gap between the circumference of the balancing tube 12 and the inner wall of the medium cylinder 5, so as to ensure that the balancing tube 12 will not be stuck in the medium cylinder 5 during the movement of the bottle stopper 2, so that the emission medium can be smoothly pushed out; the circumference of the balancing tube 12 is flush with the circumference of the sliding ring 11.

[0050] The principle and beneficial effects of the above technical solution:

[0051] During launch, since the guide block 8 is arranged in the guide groove 10 for sliding contact, when the guide tube 3 is rotated, the slide ring 11 can be driven to rotate along with the guide block 8, thereby driving the bottle plug 2 to rotate, so that the bottle plug 2 is gradually rotated out of the bottleneck 6. In the process of the bottle plug 2 rotating away from the bottleneck 6, the guide block 8 will slide upward along the guide groove 10. When the bottle plug 2 completely leaves the bottleneck 6, the high-pressure gas in the gas storage cylinder 1 can be sprayed upward, thereby pushing the slide ring 11 to move upward, and then driving the bottle plug 2 to move, breaking through the thin paper bonded to the bottom end of the medium tube 5, thereby entering the medium tube 5, and pushing the launch medium in the medium tube 5 to move toward the top end of the medium tube 5, and breaking through the thin paper at the top end, the launch medium is pushed out, and the launch of the launch medium is completed.

[0052] The cooperation between the sliding ring 11 and the balance tube 12 can expand the space occupied by the guide tube 3, so that the gas can act more on the balance tube 12 when ejecting. Such a design can increase the thrust on the bottle stopper 2 and improve the power of the bottle stopper 2. By increasing the power, it can be ensured that the emission medium can be completely pushed out of the medium tube 5 more quickly and effectively.

[0053] Embodiment three:

[0054] This embodiment is based on the second embodiment. Figure 3 As shown, the number of guide grooves 10 in the guide tube 3 is two, and the two guide grooves 10 are symmetrically arranged on the inner wall of the ring of the guide tube 3 with the axis of the guide tube 3 as the center; at the same time, the number of guide blocks 8 matches the number of guide grooves 10, that is, the number of guide blocks 8 is also two; the two guide blocks 8 are symmetrically arranged with the axis of the sliding ring 11 as the center; each guide block 8 is slidably connected to the corresponding guide groove 10; the sliding ring 11 is slidably connected to the corresponding guide groove 10 through the two guide blocks 8.

[0055] The principle and beneficial effects of the above technical solution:

[0056] The cooperation between the two guide blocks 8 and the two guide grooves 10 makes the movement in the guide tube 3 more stable and balanced. This design ensures the cooperation between the guide blocks 8 and the guide grooves 10, thereby ensuring a good guiding effect on the movement of the cork 2; through this symmetrical arrangement, the movement in the guide tube 3 has higher accuracy and reliability, avoids unstable or uneven movement, and ensures the stability and controllability of the cork 2 during rotation and movement.

[0057] In this embodiment, Figure 4As shown, an arc-shaped strip 13 is provided on the top side of the sliding ring 11; the arc-shaped strip 13 is coaxial with the sliding ring 11; the arc-shaped strip 13 is connected to the bottom side of the sliding ring 11 through two integrally formed middle blocks 14 on the bottom side of the arc-shaped strip 13; there is a gap between the arc-shaped strip 13 and the sliding ring 11, and the distance of the gap is 2cm to 3cm, ensuring that fingers can be inserted.

[0058] The principle and beneficial effects of the above technical solution:

[0059] When filling again, under the action of the guide block 8, the sliding ring 11 drives the cork 2 to move in the guide ring. When the cork 2 contacts the bottleneck 6, put your finger into the gap to drive the cork 2 to be threadedly connected with the bottleneck 6. When a part of the cork 2 is screwed into the bottleneck 6, under the cooperation of the guide block 8 and the guide groove 10, the sliding ring 11 can be driven to rotate by rotating the guide tube 3, so that the cork 2 is gradually tightened, and then the nitrogen can be filled into the gas storage cylinder 1 through the inflation valve 4.

[0060] By inserting a finger into the gap, the bottle stopper 2 can be quickly and accurately threaded with the bottle neck 6 without the need for additional tools or equipment. The cooperation of the guide block 8 and the guide groove 10 ensures the stability and accuracy of the sliding ring 11 during the connection process, making the screwing process of the bottle stopper 2 more stable and controllable.

[0061] In this embodiment, Figure 4 As shown, there are two arc-shaped bars 13 ; the two arc-shaped bars 13 are symmetrically arranged with the axis of the sliding ring 11 as the center.

[0062] The principle and beneficial effects of the above technical solution:

[0063] The symmetrical arrangement of the two arc-shaped strips 13 can enhance the balance of the bottle stopper 2, making the bottle stopper 2 more stable when being pushed by gas, and reducing unnecessary shaking or deviation.

[0064] Embodiment 4:

[0065] This embodiment is based on the first embodiment. Figure 2 , 3 As shown, a coaxial connecting ring 15 is connected to the circumferential side of the guide tube 3. Specifically, the connecting ring 15 and the guide ring are made of plastic material, such as polyethylene, and the connecting ring 15 is integrally formed on the guide tube 3; a coaxial second annular groove 16 is opened on the top side of the connecting ring 15; an intermediate ring 17 is fixedly connected to the bottom end of the medium tube 5; specifically, the medium tube 5 and the intermediate ring 17 are made of plastic material and are integrally formed; the intermediate ring 17 is threadedly connected to the second annular groove 16.

[0066] The principle and beneficial effects of the above technical solution:

[0067] Before launching the launching medium, the medium tube 5 is threadedly connected in the second annular groove 16 through the intermediate ring 17 to fix the guide tube 3, and then the guide tube 3 is rotated, so that the sliding ring 11 is driven to rotate under the action of the guide block 8, so that the bottle stopper 2 is rotated away from the bottleneck 6, and the launching medium in the medium tube 5 is pushed out under the action of the gas, and then the medium tube 5 is rotated out in the opposite direction to complete the disassembly of the medium tube 5.

[0068] In this embodiment, Figure 2 , 6 As shown, both ends of the medium tube 5 are connected with sealing paper pieces 18; the sealing paper piece 18 is disc-shaped, and is glued to the two ends of the medium tube 5 by glue. The purpose of using the sealing paper piece 18 is to ensure that the bottle stopper 2 can break through the sealing paper piece 18, so as to push out the emission medium in the medium tube 5.

[0069] The principle and beneficial effects of the above technical solution:

[0070] In the specific implementation, first, a sealing paper piece 18 is glued to the bottom end of the medium tube 5, that is, the junction with the middle tube, and then the emission medium is poured into the medium tube 5 from the other end, and then the sealing paper piece 18 is glued to the top of the medium tube 5; when the sealing paper piece 18 is broken, the medium tube 5 is removed. In this way, the emission medium can be loaded again, and the medium tube 5 can be reused. By reusing the medium tube 5, the generation of waste is reduced, the cost is effectively saved, and the utilization rate of the medium tube 5 is improved.

[0071] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
