Small water rocket capable of being launched in arbitrary direction

Abstract

The invention relates to a small water rocket capable of being launched in an arbitrary direction, belonging to the field of physical demonstrative experiments. The small water rocket is composed of a body (1) and an inflator (2), and is characterized in that a piston (3) with a small hole in the body (1) and the periphery on the inner side of the body (1) are in smooth contact with each other, and both ends of a spring (9) are respectively fixed with the piston (3) and the body (1); during filling water, a bottle opening (4) is faced up, a proper amount of water is injected into a water filling region (7), a rubber tube (6) is inserted into the bottle opening (4), and the bottle opening (4) is faced down to start inflation; the body (1) is formed by cutting and assembling an 8ml soft plastic bottle and a 10ml plastic injector, a hole in the inner top of the body (1) is sealed with a sealant (8), and the outer top of the body (1) is provided with a streamlined soft bulb (5); and the inflator (2) is formed by sheathing the rubber tube (6) on the needle column of a 50ml plastic injector. The small water rocket is mainly designed for realizing the technique of launching a water rocket in an arbitrary direction, and has more educational functions when being used in school teaching.

Description

technical field [0001] The patent of the present invention relates to an experimental instrument for demonstrating momentum change, and belongs to the field of physical experimental instruments. Background technique [0002] So far, the water rocket demonstration experimental instruments, whether used for indoor launch or outdoor launch, we have seen water rocket instruments that launch upward or obliquely upward. Once the water is launched downward, the water cannot be ejected by the gas in the water rocket. Can not play the role of water spray, affect the experimental results. There is a lack of water rockets that can be launched upwards and downwards, especially small water rockets. How to make it simple and easy, not only for teachers' classroom use, but also for students to make it safe and inspiring water rocket. Contents of the invention [0003] The invention patent focuses on solving the technology that the water rocket can be launched in any direction. It is a ...

[0002] So far, the water rocket demonstration experimental instruments, whether used for indoor launch or outdoor launch, we have seen water rocket instruments that launch upward or obliquely upward. Once launched downward, the water cannot be ejected by the gas in the water rocket. Does not have the effect of spraying water, which affects the experimental effect

There is a lack of water rockets that can be launched upwards and downwards, especially small water rockets. How to do it is simple and easy, not only for teachers' classroom use, but also for students to make it safe and instructive water rocket
