Description

Technical Field

[0001] The invention belongs to the field of toy products, in particular to a device for providing smoke effects in toy products. Background Art

[0002] Pneumatic toys include various air chambers, cylinders and other structures with air compression and propulsion, which can generate compressed airflow and mainly have the effects of shooting, blowing, and bubbling. For example, bubble gun toys, shooting toys of gun models, and weapons-type toy products such as chariots and tanks are widely popular among young players. Among these toy products, guns and weapons provide a sense of experience and perceptual cognition by imitating the shooting actions of real weapons and guns, meeting the exercise and psychological needs of young players. Some of these toy products use a combination of cylinders and pistons to provide high-pressure airflow to imitate shooting operations and improve the simulation level of the game. Some toys also add electronic circuit devices to generate sound and photoelectric effects to further enhance the fun of the product. The real weapons and guns imitated by shooting toys will produce smoke due to the combustion of gunpowder when shooting live ammunition. Therefore, in order to further enhance the simulation effect of such toy products, adding a smoke-generating structure to the product is an important choice, which can enhance the fun and attractiveness of the product. Currently, most of the related toy products on the market do not have such structural settings and need further improvement to meet the needs of the consumer market, which is also what toy manufacturers pursue. Summary of the invention

[0003] The purpose of the present invention is to provide a smoke tube type smoke generator for a pneumatic toy, which is used as a smoke generating mechanism of a simulation toy, and cooperates with a switch device of a toy product, such as a loading device and a firing device, to add a smoke spraying process to the toy product, thereby generating other dynamic effects, such as blowing bubbles, and smoke effects that simulate the shooting process, etc. The action of the smoke mechanism can be used to simulate the actual use of weapons, firearms, etc., and enhance the play function of the toy product.

[0004] To achieve the above-mentioned purpose, the technical solution of the present invention is a smoke tube type smoke generator for a pneumatic toy, comprising a main cylinder, a piston cylinder and a range hood assembly. The piston cylinder is mounted inside the main cylinder, and the piston cylinder is a hollow structure, in which a compression spring is installed. The main cylinder is connected to a push-pull mechanism, and a cylinder body one-way valve is installed on the inner side of the front air outlet. An elastic sealing cap is mounted on the front end of the piston cylinder, and a through hole cavity is formed in the middle of the sealing cap, in which a plug body one-way valve is installed. The range hood assembly comprises a range hood and an air guide rod, and the air guide rod is a hollow tubular structure, and the front and rear ends of the tubular cavity are both open. The range hood consists of a smoke generating device and an air storage cavity, and the opening of the air storage cavity is connected to the rear end opening of the tubular cavity of the air guide rod. The air guide rod is mounted in the middle of the compression spring of the piston cylinder.

[0005] The cylinder one-way valve and the plug one-way valve can adopt a ball-bead closed one-way valve or a diaphragm one-way valve. The structure of the ball-bead closed one-way valve includes a housing with openings at both ends, and a spring and a ball-bead sequentially installed and encapsulated inside the housing. The ball-bead closes one opening of the housing. When the air pressure outside the opening on one side of the ball-bead is relatively high, the air flow pushes the ball-bead away from the opening to form an air flow passage, and the air flow enters the housing body from the opening on one side of the ball-bead. When the air pressures on both sides of the ball-bead are restored to balance, the ball-bead is pushed back to its original position by the restoring force of the spring to close the opening. This structural setting enables the air flow to pass through the one-way valve in only one direction, which is beneficial to the concentration of the smoke and can generate a larger amount of smoke. At the same time, the present invention realizes the transfer and storage of the smoke from the smoke generating device to the main cylinder with the structure of a piston cylinder sleeved on the air guide rod of the oil fume device. As a component device for generating smoke in a toy product, it has the characteristics of a compact structure and can be applied to various types of pneumatic weapon and firearm products with different sizes and specifications, whether large or small.

[0006] The operation process of the present invention is as follows: The pushing and pulling mechanism guides the main cylinder and drives the piston cylinder to move backward and then reset. During the process of loading the chamber, the plug one-way valve of the piston cylinder is opened, and the smoke stored in the air guide rod and the oil fume device is inhaled into the cylinder body of the main cylinder. Subsequently, the switch device or the trigger device is triggered to cause the piston cylinder to quickly move forward and reset. Under the action of the high air pressure in the main cylinder, the cylinder one-way valve is opened, and the smoke is ejected outward from the air outlet.

[0007] Preferably, for the smoke pipe type smoke generator of the pneumatic toy with the above structure, the plug one-way valve has a sealing member, and when the piston cylinder moves backward, the sealing member blocks the front end opening of the air guide rod.

[0008] The sealing member of the plug one-way valve can be a sealing ring made of rubber material or a sealing cap with a through hole in the middle, which can completely seal the gap between the one-way valve and the air guide rod. Its advantage is that during the process of loading the chamber, when the main cylinder moves forward and resets, the negative air pressure difference formed between the inside of the main cylinder and the inner bore of the air guide rod is larger and more stable, making the conduction force of the plug one-way valve better, and the smoke in the air guide rod will not drift out from the gap between the one-way valve and the rod body, making the smoke generating effect of the toy more stable and obvious.

[0009] Optionally, for the smoke pipe type smoke generator of the pneumatic toy with the above structure, the cylinder one-way valve installed at the front end of the main cylinder body is outside the air outlet.

[0010] Setting the one-way valve of the main cylinder body outside the air outlet can better be combined and installed with other toy structures at the front end of the main cylinder, such as the ammunition loading mechanisms of the gun barrel, the cannon barrel, etc., so that the smoke generated by the smoke generator of the present invention can be concentrated and ejected outward from the opening of the ammunition loading mechanism, making the smoke effect imitating the high-intensity live ammunition shooting of submachine guns, anti-aircraft guns, etc. more realistic.

[0011] Further, for the smokestack-type smoke generator of the pneumatic toy with the above structure, the push-pull mechanism of the main cylinder is a push-pull block or a card slot structure formed on the outer wall surface, and the loading mechanism is connected to the push-pull block or inserted into the card slot for connection and fixation.

[0012] The loading mechanism refers to the structure of guns, cannons and other toys that is linked with the ammunition loading device and is used for actual loading or simulating the loading of ammunition. The main air cylinder of the present invention generates a push-pull block or a card slot structure, which is used to set the main air cylinder as a movable structure, so that the main air cylinder cooperates with the loading mechanism to realize the loading operation. The movement of the main cylinder drives the piston cylinder to slide backward, and opens the one-way valve of the plug body to inhale the smoke flowing through the inner cavity of the air guide rod, realizing the functions of simultaneous loading action (or switch startup) and the series of actions of the smoke generating mechanism to emit smoke and store smoke, simulating the action process of real weapons and firearms, and having the outstanding advantage of more prominent simulation effect.

[0013] Alternatively, for the smokestack-type smoke generator of the pneumatic toy with the above structure, the push-pull mechanism of the main cylinder has a gear rack structure on the outer wall surface and is meshed and connected with the gear disc of the gear transmission device.

[0014] Since the gear transmission device usually adopts mechanical shaking or is controlled by the cooperation of an electronic circuit and a motor, the present invention adopts a structure in which the gear transmission device is matched with the gear rack of the main cylinder for transmission. The advantage is that only by setting a certain startup program or cyclic action process for the gear transmission device, it is possible to accurately start the above-mentioned smoke generating mechanism only at the link where smoke injection is required at a fixed time, perform actions to achieve the smoke effect, and is suitable for use in some model or scenario toys.

[0015] The structural feature of the present invention is that the main cylinder serves as both a high-pressure air flow generating mechanism and a power mechanism for launching, and also as a smoke absorption and storage mechanism. Compared with other structures with similar functions, it reduces the corresponding air guide structure, minimizes the ineffective space for smoke flow, has the characteristics of a larger amount of smoke and more concentrated injection, and the advantage that the smoke injection is consistent with the timing of the shooting operation of the toy. It meets the requirements of some types of toy products for a larger amount of smoke to create a realistic effect, and is suitable for use as a structural component of a bubble gun, a toy gun, a toy war vehicle, etc. Description of the Drawings

[0019] The following will describe a preferred embodiment of the present invention with reference to the accompanying drawings.

[0020] As shown in the Figure 1 accompanying drawings, a smoke tube smoke generating device for a pneumatic toy comprises a main cylinder 1, a piston cylinder 2 and an oil fume device assembly. The oil fume device assembly includes an oil fume device 3 and a gas guide rod 4. The piston cylinder 2 is of a hollow structure, and a compression spring 5 is installed in the cavity. It can be used as a combined structure for toy products such as ordnance, firearms, and bubble guns.

[0021] Referring to the Figure 2 accompanying drawings, the outer wall surface of the main cylinder has a gear rack structure 11, which is meshed and connected with the gear disc of the gear transmission device 6. The front end of the main cylinder has an air outlet 10, and a cylinder one-way valve 12 is installed inside the air outlet. The one-way valve 12 is a tubular body, one side is installed and connected inside the air outlet, and the other side shrinks inward to form a smaller opening, and the opening is closed by a solid plastic ball 120. A soft spring 121 is placed inside the body, and the plastic ball is fixed between the air outlet and the soft spring. A return spring 13 is connected to the outer wall surface of the main cylinder, and the other end of the return spring is fixed in front of the main cylinder inside the toy product.

[0022] The piston cylinder 2 is sleeved inside the main cylinder 1, with an open front end, and a sealing cap 20 is sleeved. The sealing cap generates a ventilation hole 21, and a plug body one-way valve 22 is installed inside the ventilation hole. The plug body one-way valve 22 is a tubular body with the same structure as the cylinder one-way valve, with a spherical sealing bead 220 inside, and is limited and fixed by a soft spring 221. The sealing ball bead blocks the inside of the ventilation port.

[0023] The oil fume device 3 of the oil fume device assembly is composed of glycerin or fuming gasoline in cooperation with an electric heating device to form a smoke generating device, which is installed on the fixed structure of the toy product. The gas guide rod is connected to the smoke outlet of the smoke generating device and is inserted into the middle of the compression spring of the piston cylinder, so that the compression spring 5 is sleeved between the main cylinder 1 and the smoke generating device. The smoke generated by the smoke generating device is stored in the air storage cavity and the inner cavity of the gas guide rod.

[0024] The operation process of this embodiment is as follows: After triggering the switch device, the motor 7 and the gear transmission device 6 act, and the gear rack 11 moves accordingly, pulling the main cylinder, moving backward together with the piston cylinder, and the compression spring is compressed until the one-way valve of the piston cylinder contacts the front end opening of the gas guide rod and stops. Subsequently, the gear transmission mechanism guides the main cylinder to move forward and reset, and the piston cylinder is temporarily fixed by being stuck by the trigger structure or switch structure of the toy, completing a loading process. As shown in the Figure 2As shown, the reset spring 13 assists in returning the main cylinder to its initial position during the loading operation. During the above operation, while the main cylinder is moving forward for reset, a vacuum state is formed inside it. Under the action of the air pressure difference, the spherical sealing bead 220 of the plug check valve moves forward, opening the vent port, and the smoke stored in the air storage cavity and the air guide rod of the oil fume device assembly is sucked into the main cylinder body.

[0025] See the appendix Figure 3 Refer to the attached figure. Pull the trigger or activate the switch device to release the piston cylinder 2. Under the action of the reset elastic force of the compression spring 5, the piston cylinder rapidly moves forward for reset. The air inside the main cylinder body 1 is compressed, and the sealing bead 220 of the plug check valve 22 closes the rear opening under the action of the soft spring 221. After the air inside the main cylinder body is compressed, the air pressure difference with the outside causes the ball 120 of the cylinder check valve 12 to leave the rear opening of the check valve, and the main cylinder body is connected to the outside. Under the push of the piston cylinder, as the gas inside the main cylinder body is continuously compressed, a greater pressure difference state is generated, and the smoke stored in the main cylinder body rapidly jets outwards through the air outlet 10. At the same time, the high-speed airflow leaving the main cylinder body can also push the bullet 7 or other launching objects placed in front of it to move, completing the shooting action. Through this series of mechanical transmissions, a large amount of smoke can be generated while actually or simulating ammunition firing, and it jets out from the toy's launch port. It has the characteristics of concentrated smoke and the jet position being consistent with the launch position, strengthening the simulated shooting function of the pneumatic toy, and the effect is more realistic.

[0026] As above, a preferred embodiment of the present invention has been described with reference to the accompanying drawings, but it does not mean that it is limited to the structure of the embodiment. All kinds of modifications, equivalent replacements, and additions within the technical scope expressed by the claims of the present invention. For example, the main cylinder body is set to be fixed, and the smoke generation process is only achieved by pulling the piston cylinder to slide back and forth through an external structure; other pushing and pulling mechanisms such as a pushing and pulling block or a clamping groove structure are arranged on the outer wall surface of the main cylinder body, and similar structural changes certainly also belong to the technical scope described by the present invention.
