airflow control device for toy guns

Abstract

This invention relates to an airflow control device for a toy gun. The device includes a sliding nozzle, an air outlet, an air inlet, an air outlet channel, an air outlet channel, an airflow control component, an elastic element, a closed end, at least one positioning part, a limiting slide rail, and a limiting member, all disposed within the toy gun. When the toy gun fires a projectile, gas enters through the air inlet of the sliding nozzle, exits through the air outlet channel, and completes firing. The airflow control component then moves forward due to the pressure difference, causing the closed end to seal the air outlet channel, resulting in a reverse flow of gas and generating recoil. The elastic element then pushes the airflow control component backward. Due to the design of the positioning part and the limiting member, the airflow control component can only move within the range of the limiting slide rail. This prevents the airflow control component from getting stuck at one end, affecting air exchange, and especially avoids high-speed circulation jamming and incomplete stroke switching during continuous fire.

Description

airflow control device for toy guns Technical Field

[0001] This invention provides an airflow control device for a toy gun that can improve positioning accuracy, stabilize high-speed switching, and improve the consistency of continuous firing. Prior Technology

[0002] Note that the structure of pneumatic toy guns widely adopts a combination of nozzle and floating valve to switch the airflow for propelling BBs and the recoil air passage of the slide. The floating valve is also known as an airflow switching valve, or commonly referred to as an airplane or dart. It is generally a slender movable part. The movement of the floating valve mostly relies on the inner wall of the cylindrical nozzle for guidance and is positioned by a spring. During shooting, it moves back and forth in the inner cavity of the nozzle to complete the two functions of propelling BBs and recoil circulation. Current improvements are only based on simplifying the number of parts and reducing manufacturing costs.

[0003] However, under continuous firing (rapid fire) conditions, the floating valve is prone to jamming, commonly known as "floating valve jamming." The causes are often related to structural tolerances, material wear, insufficient lubrication, uneven spring force, air pressure fluctuations, and momentary eccentricity caused by high-speed circulation. However, players generally report that it's not simply due to wear or lack of lubrication, but rather related to inherent design limitations of the existing structure. Specifically, during high-speed circulation, the floating valve needs to complete the switch between two positions—"fully front-closed" and "fully rear-closed"—in a very short time. If either position fails to reach the designed stroke, it will cause abnormal air path switching. Some conventional designs use a single, slender guide surface without a matching auxiliary positioning structure, making the floating valve prone to slight eccentricity during high-frequency reciprocating motion. This causes friction to concentrate in a localized area, significantly increasing the probability of jamming.

[0004] The jamming problem under continuous firing conditions manifests as mid-fire stagnation. The floating valve may remain in a position between forward extension and backward retraction, causing the airflow to be neither fully used for propelling the bullet nor fully guided to the recoil. Ultimately, due to uneven rate of fire, insufficient recoil, increased bullet dispersion, single-shot energy decay, and abnormal gas consumption, shooting instability occurs. Even the instantaneous pressure difference fluctuation of gas during continuous firing can create additional bias force on the floating valve, easily causing it to get stuck in a single position, resulting in unexpected actions such as "propelling the bullet without recoil" or "recoiling without propelling the bullet." This is a structural design defect, rather than simply a matter of material wear.

[0005] Existing manufacturers often try to improve the situation by increasing lubrication or replacing springs, but the effects are limited. The root cause lies in design factors such as insufficient guide stroke margin, a single positioning interface, or failure to consider transient air pressure. Therefore, burst fire jamming is considered a known bottleneck in the design of floating valves for pneumatic toy guns, and it is particularly prone to malfunctions in high-speed firing modes, representing a technical problem that still needs improvement.

[0006] Therefore, how to solve the aforementioned problems and shortcomings of conventional methods is the direction that the applicant of this new type of invention and related manufacturers in this industry urgently want to study and improve. Summary of the Invention

[0007] Therefore, in view of the above-mentioned deficiencies, the applicant of this invention collected relevant information, conducted multiple evaluations and considerations, and, based on years of experience accumulated in this industry, through continuous trial and modification, designed this new patent holder for an airflow control device for toy guns that can improve positioning accuracy, stabilize high-speed switching, and improve burst firing consistency.

[0008] The main purpose of this new invention is to limit the pushing position limit of the airflow control component by using the design of the positioning part, the limiting part and the limiting slide rail, so as to control the movement stroke and time of the airflow control component, ensure the smoothness of the airflow direction switching, avoid jamming at one end and affecting the ventilation, and especially avoid high-speed circulation jamming and incomplete stroke switching during continuous firing.

[0009] To achieve the above objectives, the structure of this novel component includes: a sliding nozzle, an air outlet, an air inlet, an air nozzle channel, an airflow control component, an elastic element, a closed end, at least one positioning part, a limiting slide rail, and a limiting component. The sliding nozzle is located inside a toy gun. The air outlet is formed at one end of the sliding nozzle and connects to the chamber of the toy gun. The air inlet is formed on the side of the sliding nozzle opposite to the air outlet. The air outlet channel is formed between the air outlet and the air inlet. The airflow control component is movably disposed in the air outlet channel and moves between a push position with the air outlet open and a recoil position with the air outlet closed. The elastic element is disposed on the airflow control component to use elastic force to return the airflow control component to the push position. The closed end is formed at the end of the airflow control component opposite to the elastic element to close the air outlet channel when the airflow control component is in the recoil position. The positioning part is disposed on the sliding nozzle. The limiting slide rail is disposed on the airflow control component, and the limiting component is fixed on the positioning part and passes through the limiting slide rail to limit the movement range of the airflow control component.

[0010] When the user applies this new design to the airflow control of a toy gun, each time the toy gun fires and propels a bullet, gas enters through the air inlet of the sliding nozzle, exits through the nozzle channel, and completes the firing action. Immediately, the airflow control component moves towards the outlet due to the pressure difference, sealing the nozzle channel and causing the gas to flow in reverse, generating recoil. The elastic element then pushes the airflow control component in the opposite direction. At this point, due to the design of the positioning and limiting parts, the airflow control component can only move within the range of the limiting slide rail. Because the travel distance of the airflow control component is shortened, it avoids the component getting stuck at one end, affecting air exchange, and especially avoids problems such as high-speed gas circulation jamming and incomplete stroke switching during continuous fire.

[0011] By employing the aforementioned technologies, we can overcome the problems of high-speed cycle jamming, incomplete stroke switching, and lack of consideration for transient air pressure in the floating valve design of conventional pneumatic toy guns, thus achieving the practical advancements mentioned above.

Implementation

[0013] To achieve the above objectives and effects, the technical means and structure adopted by this invention are described in detail below with reference to the preferred embodiment of this invention, so as to facilitate a complete understanding.

[0014] Please refer to Figures 1-4, which are perspective views and schematic diagrams of the first preferred embodiment of the present invention. The figures clearly show that the present invention includes:

[0015] A sliding air nozzle 1 is installed inside a toy gun 9;

[0016] An air outlet 11 is formed at one end of the sliding sleeve nozzle 1 and is connected to the chamber 91 of the toy gun 9;

[0017] An air inlet 12 is formed on the side of the sliding sleeve nozzle 1 opposite to the air outlet 11;

[0018] An air nozzle channel 13 is formed between the air outlet 11 and the air inlet 12;

[0019] An airflow control component 2 is movably disposed within the air nozzle channel 13 and moves between a push-button position where the air outlet 11 is open and a recoil position where the air outlet 11 is closed.

[0020] An elastic element 3 is provided on the airflow control component 2 to use elastic force to return the airflow control component 2 to the push position;

[0021] A closed end 21 is formed at the end of the airflow control member 2 away from the elastic element 3, so as to close the air nozzle passage 13 when the airflow control member 2 is in the rear seat position;

[0022] At least one positioning part 14 is provided on the sliding sleeve nozzle 1;

[0023] A limiting slide rail 22 is mounted on the airflow control component 2; and

[0024] A limiting member 4 is fixed on the positioning part 14 and passes through the limiting slide rail 22 to limit the movement range of the airflow control member 2. The limiting member 4 has at least one pressing part 41 for pressing the inner wall of the positioning part 14.

[0025] For ease of understanding, the front and rear positions of all components are defined uniformly with the muzzle direction of the toy gun 9 as the front. The sliding nozzle 1 is an existing structure within the pneumatic toy gun 9, and its air intake method is exemplified by an open-joint type. Therefore, when it moves backward, it makes way for the BB pellet's feeding path, and the resetting action allows the BB pellet to enter the chamber 91 to complete loading (ready to fire). At the same time, the front air outlet 11 is sealed and connected to the chamber 91, and the air inlet 12 is also connected to the high-pressure air source channel 93. The specific linkage mechanism of the sliding nozzle 1 will not be described in detail. The positioning part 14 is a through hole, screw hole, or slot. In this embodiment, the upper and lower screw holes are used as an example. The limiting part 4 is a bolt or screw. In this embodiment, the upper and lower screw holes are used as an example. Taking the screw corresponding to the positioning part 14 as an example, the pressing part 41 is its thread. In this embodiment, an internal hexagon screw is used as an example. The airflow control component 2 is a bullet-shaped floating valve (also known as an airflow switching valve, or commonly known as an airplane or dart). Its closed end 21 at the rear end is a flat-headed conical structure with a diameter larger than that of the airflow control component 2 body. The limiting slide rail 22 is a capsule-shaped hole or groove that penetrates the airflow control component 2 body. In this embodiment, a hole is used as an example. The elastic element 3 is a compression spring, with one end fixed to the airflow control component 2 and the other end abutting against the inside of the air outlet 11. However, the corresponding forms of the above-mentioned components are only examples of preferred embodiments. Any form with the same function is within the scope of this invention and is not limited to the above examples.

[0026] The above explanation has provided an understanding of the structure of this technology. By matching this structure with other technologies, it is possible to achieve advantages such as improved positioning accuracy, stable high-speed switching, and improved consistency of continuous firing. A detailed explanation will follow below.

[0027] Please refer to Figures 1-9 for a perspective view of the first preferred embodiment of this invention. As can be clearly seen from the figures, when the above components are assembled, the airflow control component 2 and the sliding nozzle 1 are connected by simply placing the airflow control component 2 into the nozzle channel 13 and aligning the limiting slide rail 22 roughly with the positioning part 14. Then, the limiting component 4 is inserted from the positioning part 14 on the upper side of the sliding nozzle 1 and, after passing through the limiting slide rail 22, is connected to the positioning part 14 on the lower side of the sliding nozzle 1. This completes the setting of the airflow control component 2. Compared with the traditional floating valve, although an additional action of setting the limiting component 4 is required, this action is simple and quick, and the required design changes are also very simple, yet it can achieve the multiple functions of this invention. The specific explanation is as follows.

[0028] Before each firing of the toy gun 9, the sliding gas nozzle 1, along with the bolt 92, is pulled backward, separating the gas outlet 11 from the chamber 91 and creating space for the BB pellet 8 to enter. Then, the sliding gas nozzle 1 returns to its forward position due to the elastic force, using the end wall on one side of the gas outlet 11 to push the BB pellet 8 into the chamber 91. At this time, the gas outlet 11 and the chamber 91 are sealed and connected. At the same time, the gas inlet 12 is also connected to the high-pressure gas source channel 93. Therefore, the output of high-pressure gas will enter through the gas inlet 12 of the sliding gas nozzle 1 and fill the gas nozzle channel 13 and the cylinder (the space freed up by the bolt 92 moving backward). However, since the air pressure around the airflow control component 2 is uniform and it is not pushed by the gas pressure, the airflow control component 2 is limited by the elastic force of the elastic element 3 and can only be located on the side of the BB-pushing position P1.

[0029] When the toy gun 9 is fired, the bolt 92 is instantly pushed forward, causing the gas in the cylinder to be pushed towards the sliding nozzle 1 and discharged from the outlet 11 through the nozzle channel 13. This gas pressure is used to push out the BB pellet 8, completing the firing action. At the same time, the airflow control component 2 is also pushed forward by this gas pressure. In addition, after the BB pellet 8 leaves the barrel, the high-pressure gas in the barrel, chamber 91 and nozzle channel 13 is released, and the gas pressure drops instantly. This causes the airflow control component 2 to move towards the outlet 11 due to the pressure difference. The airflow control component 2 overcomes the elastic force of the elastic element 3, causing the sealing end 21 to close the nozzle channel 13. At this time, the airflow control component 2 is located in the recoil position P2. However, because the air inlet 12 is still connected to the high-pressure gas source channel 93, the high-pressure gas can only act backward on the cylinder head 921. The reverse flow of gas pushes the bolt 92 again, generating recoil force.

[0030] Next, because the rearward movement of the bolt carrier 92 also cuts off the supply of high-pressure gas, the airflow control component 2, which has lost the push of high-pressure gas, is pushed backward by the elastic element 3 to return to its original position. At this time, due to the design of the positioning part 14 and the limiting part 4, the airflow control component 2 can only move within the range of the limiting slide rail 22. This ensures that the position of the airflow control component 2 after returning to its original position allows the air inlet 12 to connect with the air nozzle channel 13, and it will not be unable to return to the recoil position P2 because it is too close to the cylinder head 921. In this way, the airflow control component 2 is prevented from getting stuck at one end and affecting the air exchange. Also, because the movement stroke of the airflow control component 2 is shortened, the problems of high-speed gas circulation jamming and incomplete stroke switching during continuous fire can be avoided in particular.

[0031] Please refer to Figures 10-12, which are exploded views to perspective sectional views of the second preferred embodiment of this invention. As can be clearly seen from the figures, the main differences between this embodiment and the above embodiments include: the limiting slide rail 22 has a supporting height 221 on the side away from the closed end 21, and the contact area between the supporting height 221 and the limiting member 4 is larger than the contact area between the limiting slide rail 22 and the limiting member 4; the airflow control member 2 has at least one reinforcing part 222, which extends from one side of the supporting height 221; a fixing part 23 is provided between the reinforcing part 222 and the supporting height 221 for mounting the elastic element 3; and the closed end 21 has at least one slide rail guide part 211 for guiding the limiting slide rail 22 to correspond to the position of the positioning part 14. Accordingly, the main change in this embodiment is to the detailed structure of the airflow control component 2, changing the original bullet-shaped body part to a cross-shaped structure, so as to reduce the space occupied by the airflow control component 2 in the air nozzle channel 13, thereby increasing the actual air passage cross area and making the airflow smoother. In addition, the longitudinal wall of the cross-shaped structure can be used to support the limiting component 4 over a large area, avoiding the limiting slide rail 22 from being subjected to excessive pressure concentration due to the small contact area when supporting the limiting component 4, which would increase the risk of the limiting component 4 breaking. Therefore, the supporting height 221 is the longitudinal wall of the cross-shaped structure, the reinforcing part 222 is a cross-shaped structure, and the fixing part 23 is the groove between the reinforcing part 222 and the supporting height 221 to provide the fixing action of the elastic element 3. Furthermore, two inferior arcs are cut off from both sides of the originally circular closed end 21 to form two cross sections. At the same time, two planes 15 corresponding to these two cross sections are designed on the inner wall of the sliding sleeve nozzle 1. These cross sections are the slide rail guide part 211. In this way, when the airflow control component 2 is set inside the sliding sleeve nozzle 1, as long as the position of the slide rail guide part 211 corresponds to the position of the plane 15 inside the sliding sleeve nozzle 1, the position of the limiting slide rail 22 and the positioning part 14 can be ensured, and the limiting component 4 can pass through the limiting slide rail 22 normally. Since the airflow control component 2 is very small, it is difficult to make the position of the limiting slide rail 22 and the positioning part 14 correspond in a narrow and dark space. Therefore, by using the design of the slide rail guide part 211, the concept of setting direction to prevent mistakes can be used to effectively solve the above problems.

[0032] In addition, a stop portion 42 is provided at the end of the limiting member 4. In this embodiment, the limiting member 4 is a plug. Therefore, the part of the limiting member 4 whose diameter is larger than that of the positioning part 14 is defined as the tight part 41, and the side flange at the top of the plug is defined as the stop portion 42, which is used to ensure the connection between the limiting member 4 and the positioning part 14. If it is a large-head screw, the screw head is the stop portion 42. Otherwise, if it is an internal hex screw, the stop portion 42 does not exist.

[0033] However, the above description is only a preferred embodiment of the present invention and does not limit the scope of the patent of the present invention. Therefore, any simple modifications and equivalent structural changes made using the contents of the present invention's specification and drawings should also be included within the scope of the patent of the present invention and are hereby stated.

[0034] Therefore, the key to improving upon conventional technologies lies in the airflow control device of this new toy gun:

[0035] First, by utilizing the design of the positioning part 14, the limiting part 4 and the limiting slide rail 22, the pushing position P1 limit of the airflow control part 2 is limited, so as to control the movement stroke and time of the airflow control part 2, ensure the smoothness of the airflow direction switching, avoid jamming at one end and affecting ventilation, and especially avoid high-speed cycle jamming and incomplete stroke switching during continuous firing.

[0036] Secondly, by placing the elastic element 3 at the front end of the airflow control component 2, the airflow switching time can be advanced. Combined with the limiting component 4, the stroke of the airflow control component 2 can be shortened, and the switching speed can be accelerated. This provides more stable support for lightweight BB bullets 8 or higher firing rates.

[0037] Third, by utilizing the design of the reinforcing part 222, the volume of the airflow control component 2 is reduced and the airflow is increased, while the structural strength of the airflow control component 2 is increased and its service life is extended.

[0038] Fourth, by utilizing the design of the supporting high part 221, the force application point of the limiting slide rail 22 against the limiting member 4 is dispersed, so as to avoid excessive pressure concentration and increase the risk of breakage of the limiting member 4.

[0039] Fifth, by utilizing the design of the tight part 41, the action of fixing the limiting part 4 to the positioning part 14 can be simplified, achieving the advantage of easy assembly.

[0040] Sixth, by utilizing the design of the stop part 42, the engagement depth of the limiting member 4 can be limited, so that it engages with the positioning part 14 in the best fit position, thereby indirectly improving the fixing strength of the limiting member 4.

[0041] Seventh, by utilizing the design of the guide rail 211, the limiting slide rail 22 and the positioning part 14 can be accurately aligned, thus ensuring that the limiting member 4 can be properly inserted into the limiting slide rail 22.
