Water rocket

Abstract

The invention relates to a water rocket, which comprises a rocket body, a base, a sealing device and an inflating device, wherein the inner part of the rocket body is hollow, and a first connecting part formed on the lower end part of the rocket body; the base comprises a mounting seat and a plurality of elastic tail wings detachably connected to the mounting seat, a first through hole is formed in the mounting seat, and the mounting seat is detachably connected to the first connecting part; the sealing device comprises a sealing column and a sealing ring arranged at the upper end part of the sealing column, and the upper end part of the sealing column is inserted into the first through hole; and the inflating device comprises an inflating pipeline and an inflating cylinder, one end of the inflating pipeline is connected with the inflating cylinder, and the other end of the inflating pipeline is connected with the sealing device. According to the technical scheme, the base is arranged at the lower end of the rocket body, the sealing device is connected with the base, one end of the inflating pipeline is connected with the sealing device, and the other end of the inflating pipeline is connected with the inflating cylinder, so that the water rocket does not flow back during inflation, the inflating pipeline can be lengthened, the flight height can be controlled by setting the number of the sealing rings, and the water rocket has good applicability.

Description

technical field [0001] The invention relates to the field of educational toys, in particular to a water rocket. Background technique [0002] Water rockets, also known as pneumatic water-jet rockets and water-propelled rockets, are experimental devices / equipment designed using mass ratio and air pressure. The principle is to inject gas into the airtight arrow body filled with a certain amount of water, and as the air pressure in the arrow body rises, the sealing plug at the bottom is washed away, so that the water is ejected quickly, so that the arrow body obtains an upward reverse thrust, and the arrow body rises It shoots out like a rocket, so it is named Water Rocket. [0003] Existing water rockets all comprise rocket bodies, bases, sealing devices and inflatable devices, but the existing water rockets have a single way of playing and few changes, so entertainment and practicability are relatively poor. The existing base cannot be deformed, so that the water rocket can...

[0003] Existing water rockets all include rocket bodies, bases, sealing devices and inflatable devices, but the existing water rockets have a single way of playing and few changes, so entertainment and practicability are poor

The existing base cannot be deformed, so that the water rocket can only rise in a straight line, lacks changes, and has poor practicability; the existing sealing device can only play a sealing role, and cannot control the water rocket by changing the degree of sealing. Therefore, the existing water rockets have poor adaptability to different sites; the inflatable device includes an inflatable pipeline and an inflatable cylinder, and the existing inflatable pipeline can only maintain the original length, and several shorter pipeline bodies cannot be combined into one The pipeline body is relatively long, so the distance between the user and the water rocket cannot be changed according to actual needs, and the practicability is poor; and the existing inflators are not effective in preventing gas backflow, and it is time-consuming and labor-intensive for the user to inflate
