Description

Technical Field

[0001] This utility model belongs to the field of water rocket launch, and in particular relates to a small water rocket pressurization integrated launch device. Background Technology

[0002] Water rockets are toys designed using mass ratio and air pressure. They are also a well-known case study in physics teaching, which can cultivate students' interest in learning physics. The physical principles they contain are an important foundation for understanding mechanics in physics.

[0003] During the use of water rockets, water and high-pressure gas are usually added into the water rocket, and then the valve is released, causing the water rocket to be ejected under high pressure. Currently, most of the devices for adding gas into water rockets are large in size and need to be placed on the ground. The water rocket is pressurized by an air pump or air cylinder.

[0004] However, these pressurizing devices are generally large and suitable for use in large outdoor spaces, but they are not easy to carry or move during teaching, and they are also not convenient for younger or weaker students to use. Utility Model Content

[0005] In view of this, the present invention aims to provide a small water rocket pressurization integrated launch device to miniaturize the water rocket pressurization connection part so as to facilitate the carrying of the connection part.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] A small water rocket pressurization integrated launch device, comprising:

[0008] The connecting part includes a connector for fixing the water rocket and communicating with the internal space of the water rocket;

[0009] A pressurized chamber, the internal space of which can be compressed or expanded;

[0010] The connecting unit is provided with a first connection port and a second connection port. The pressurizing chamber and the connecting part are respectively connected to the first connection port and the second connection port. A first one-way valve is provided between the connecting part and the connecting unit. When the pressurizing chamber space is compressed, the medium in the pressurizing chamber can flow to the connecting part through the first one-way valve.

[0011] Furthermore, the communication unit also includes a third connection port, which is connected to the outside through a second one-way valve, and when the internal space of the pressurization chamber expands, the external medium can enter the pressurization chamber.

[0012] Furthermore, it also includes a pressurizing bottle, which contains a piston that divides the internal space of the pressurizing bottle into a pressurizing chamber and a movable chamber that are not connected to each other.

[0013] Furthermore, the active cavity has breathing holes on its wall.

[0014] Furthermore, the piston is fixedly connected to a push-pull rod, and the end of the push-pull rod extends outward from the pressurized bottle.

[0015] Furthermore, the inlet of the second one-way valve is provided with a connecting nozzle, which can be connected to a hose.

[0016] Furthermore, the launching device also includes a housing, the communication unit is placed inside the housing, and a water baffle is fixed to the housing near the first one-way valve.

[0017] Furthermore, an extension rod is fixedly provided on the movable outer ring of the connector, and a trigger is provided at the end of the extension rod in a direction away from the connector.

[0018] Furthermore, a slot is provided on the water shield, through which the extension rod can pass. The trigger and connector are respectively located on both sides of the water shield.

[0019] Furthermore, the outlet of the first check valve is connected to the connection part through a connecting pipe, and a pressure gauge is fixed on the connecting pipe.

[0020] Compared with existing technologies, the small water rocket pressurization integrated launch device of this utility model has the following advantages:

[0021] This invention utilizes the cooperation of two one-way valves and a piston to fill the water rocket with water and gas. Compared with existing technologies, it reduces the volume of water and gas required for filling the water rocket, thereby reducing launch preparation time and making the launch process more convenient and faster. During operation, when used with a small water rocket, it can reduce the air pressure required for launch, as well as the time and difficulty of filling. It also opens up more possibilities for the use of water rockets, such as indoor use or handheld launchers, enhancing the application and teaching fun of water rockets.

[0022] The connection between the nozzle and hose facilitates the connection between the launch device and the water source, making it easier for operators to inject the right amount of water precisely into the water rocket.

[0023] A water shield is used to prevent water vapor from spraying onto the operators when the water rocket is fired. Attached Figure Description

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] The small water rocket pressurization integrated launch device of this utility model includes a connecting part 1, which includes a connector 11 for fixing the water rocket and communicating with the internal space of the water rocket. Specifically, the specific structure of the connector 11 is prior art, which includes a movable outer ring 12 that can move along the axial direction of the connector 11 and a quick connector for communicating with the water rocket. In use, the water rocket is connected to the quick connector and fixed by the movable outer ring 12. Then, by pressing down the movable outer ring 12, the water rocket is separated from the connecting structure and ejected outward under the action of internal air pressure. Those skilled in the art can make the connecting part 1 themselves or purchase an existing water rocket launcher as the connecting part 1. The connecting part 1 is connected to a pressurization chamber 22 through a communication unit 3, and gas and / or liquid are filled into the connecting part 1 through a pressurization bottle 2. The connecting unit 3 includes a first connecting port 31 and a second connecting port 32. In this embodiment, the first connecting port 31 is connected to the connecting part through a first one-way valve, and the pressurizing bottle is connected to the second connecting port 32. A connecting space 36 is left between the first connecting port 31 and the second connecting port 32. When the pressure in the connecting space 36 is greater than the pressure in the connecting part 1, the first one-way valve 34 opens, allowing the medium in the connecting space 36 to enter the water rocket through the first one-way valve 34 and the connecting part 1. Specifically, the internal space of the pressurizing chamber can be compressed or expanded. When the internal space of the pressurizing chamber is compressed, the air pressure increases due to the reduction in the internal volume of the pressurizing chamber, thus causing the squeezing... The pressure inside the pressurization chamber can be greater than the internal pressure of the water rocket, allowing the medium in the pressurization chamber to enter the water rocket and complete the internal pressurization process. In this embodiment, the pressurization chamber is located inside a pressurization bottle, and a piston that cooperates with the pressurization bottle compresses or expands the internal space of the pressurization chamber. In other embodiments, the pressurization chamber can also be a rubber or other inflatable balloon, which may have a one-way valve to allow gas to be repeatedly injected into the water rocket through the first one-way valve 34. Alternatively, the pressurization bottle can be an air pump, where the change in the pump's cup during movement creates a one-way valve effect, allowing gas to be repeatedly injected into the water rocket through the first one-way valve 34. During use, the operator can pre-add a preset amount of water or other medium to the water rocket as needed, then install the water rocket on the connector, pressurize the water rocket with high-pressure gas through the pressurization chamber to reach the preset pressure, and then move the movable outer ring of the connector to separate the water rocket from the connector under pressure.Thus, the device, consisting of a pressurization bottle, a connecting unit, and a connecting part, can complete the connection, pressurization, and launch of the water rocket. This reduces the number of components required for the use of the water rocket, thereby reducing the size of the launch device and making it easier for operators to carry and use. During operation, if used with a small water rocket, it reduces the air pressure required for the water rocket launch, as well as the time and difficulty of inflation. It also opens up more possibilities for the use of water rockets, such as indoor use or as a handheld launcher, and adds fun to the application and teaching of water rockets.

[0037] In this embodiment, the communication unit is further provided with a third connection port 33. One end of the third connection port 33 is connected to the communication space 36, and the other end is connected to the outside through a second one-way valve. When the pressure inside the communication space is less than that outside, the second one-way valve opens, allowing external gas or liquid media to enter the communication space. Specifically, when the internal space of the pressurizing chamber expands, the air pressure in the pressurizing chamber and the communication space decreases, so that the air pressure in the pressurizing chamber and the communication space is equal to the external air pressure. The external air pressure opens the second one-way valve, allowing the medium to enter the communication space and / or the pressurizing chamber, and enter the water rocket through the first one-way valve during the contraction of the pressurizing chamber space.

[0038] In this embodiment, the pressurization chamber is placed inside a pressurization bottle, and a piston is provided inside the pressurization bottle. The piston divides the space inside the pressurization bottle into a non-communicating pressurization chamber and a movable chamber, and the piston can move inside the pressurization bottle, causing changes in the internal volume of the pressurization chamber and the movable chamber. Thus, a water rocket launch device is constructed with a relatively simple structure, making it easier to handle and carry. During use, water and / or air can be injected into the water rocket by repeatedly pulling the piston 21, thereby ensuring that the internal air pressure of the water rocket meets the launch conditions.

[0039] The pressurizing bottle 2 also includes a movable chamber 23. In other words, the space inside the pressurizing bottle 2 is divided into a pressurizing chamber 22 and a movable chamber 23 by a piston 21. An exhalation hole is opened on the wall of the movable chamber 23. The piston 21 is fixed to the end of a pull rod 25. The pull rod 25 passes through the wall of the end of the movable chamber 23, so that the end of the pull rod 25 away from the piston 21 is placed outside the pressurizing bottle 2, so as to facilitate the operator's operation.

[0040] The second one-way valve 35 has a connecting nozzle 37 at its medium inlet. A flexible hose can connect to the connecting unit 3 through the connecting nozzle 37. During use, the connecting unit 3 can be connected to a water source via the hose. The water source can be natural water or a container such as a measuring cup containing the medium to be injected into the water rocket. Then, by pulling the piston 21, an appropriate amount of water from the water source is forced into the water rocket through the first one-way valve 34, thus completing the water injection into the water rocket. Afterward, the hose is removed or moved away from the water source, and the piston 21 is pulled again to allow outside air to enter the water rocket, completing the pressurization of the water rocket. It is worth noting that when the hose is not connected to this launching device, the operator can also fill the second one-way valve 35 with water and inject water into the water rocket by pulling the piston 21, or directly connect the water-filled water rocket to the connector 11 and pressurize the water rocket by pulling the piston 21 for use.

[0041] The medium outlet of the first one-way valve 34 is also connected to a connecting pipe 8, that is, the first one-way valve 34 is connected to the connector 11 through the connecting pipe 8. The connecting pipe 8 is equipped with a pressure gauge 7 to measure the pressure inside the water rocket.

[0042] Optionally, in some embodiments, the small water rocket pressurization integrated launching device described in this application further includes a housing 9. The connection positions of the connecting unit 3, the first one-way valve 34, the second one-way valve 35, and the pressurization bottle 2 are placed inside the housing 9 to protect each connection position. In this embodiment, the housing 9 is designed with a shape similar to a gunstock for easy grip by the operator. At the same time, a water shield 6 is provided on the housing 9 near the first one-way valve 34. The water shield 6 is arc-shaped, and its opening faces the connection part 1, so that when the water rocket is ejected, the ejected water and air impact the water shield 6, preventing water and air from directly injuring the operator. An extension rod 5 is fixedly mounted on the movable outer ring 12 of the connector 11, and the extension rod 5 extends away from the connector 11. A slot is opened on the water shield 6, through which the extension rod 5 can pass. A trigger 51 is fixedly mounted at the end of the extension rod 5, away from the connector 11. When in use, the operator can hold the launching device through the outer casing 9, and by pulling the trigger 51, move the extension rod 5, causing the movable outer ring 12 to move, thus disengaging the water rocket and allowing it to be ejected outwards under internal pressure. This allows the launching device to be held in the hand, controlling the launch direction and increasing the fun of the activity.

[0043] In another embodiment, the connecting part 1 can also be fixed on a launcher, and the launch angle can be adjusted by the launcher. The connecting unit 3 is connected to the connecting part 1 through a flexible tube to fill the water rocket with water and / or gas. Then, the movable outer ring 12 is moved to unlock the water rocket by means of pulling or other methods to complete the launch.

[0044] Those skilled in the art should know that the connection between various pipes, heads and other parts can be made by screwing or plugging, and the specific connection methods and structures are existing technologies. The structure of the one-way valve is also existing technology and will not be described again.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
