Description

[Detailed description of the invention] [Industrial application field] This invention relates to a piston type water gun toy.

[Prior Art] Conventionally, a piston-type water gun toy has been made up of a cylinder tube with one water discharge hole provided on the tip surface, a piston that is slidably fitted into the cylinder tube, and a piston rod that pushes and pulls the piston. is known as a well-known technology.

[Problems to be solved by the invention] However, in the conventional water gun toy, a water suction operation must be performed every time water is released, by plunging the tip of the cylinder into the water and pulling up the piston, which is very troublesome. Furthermore, with a nozzle structure in which a single water discharge hole was provided on the tip of the cylinder, although it was possible to discharge water as a water gun, there was a problem in that it could not be used to switch to spraying water in the form of a mist. .

[Means for Solving the Problems] In order to solve the above-mentioned problems, this invention is equipped with a handle-shaped water tank with a water filling cap, and an outer pipe holder is fitted into the upper front protrusion of this water tank. Connect the water suction tube that curves and hangs down inside the water tank to the inward protruding port of the outer pipe holder, and insert and fix one end of the outer pipe to the outward protruding port of the outer pipe holder to connect the water suction tube to the front of the water tank. An inner pipe and a perforated piston with an O-ring inserted and fixed into the inner end of the inner pipe are slid into this outer pipe, and a grip tube is inserted and fixed into the tip of this inner pipe. An inner nozzle body having two water fountain holes and an end groove communicating between the water fountain holes is fitted into the inner hole at the tip of the grip tube, and an end wall portion that approaches and separates from the tip surface of the inner nozzle body. Then, an outer cap nozzle for switching between water sprinkling and water discharge, which has one nozzle hole provided in the center of the end wall, is screwed into the threaded end of the grip tube, so that the inside of the outer pipe holder and the grip tube It is characterized by a pair of check valves built into the inner hole at the tip.

[Operation] Fill the water tank, hold the water tank with one hand, hold the grip tube with the other hand, and pull so that the inner and outer pipes extend.The forward movement of the perforated piston will cause the tank side to reverse. The stop valve is opened and the check valve on the nozzle side is closed, and the water in the water tank is sucked into the inner and outer pipes and the grip pipe through the water suction tube.

Next, when the inner pipe is pushed into the outer pipe so that the inner and outer pipes contract, the check valve on the tank side closes and the check valve on the nozzle side opens due to the backward movement of the perforated piston. The suction water in the grip tube is discharged from the nozzle hole of the outer cap nozzle. In this case, when the outer cap nozzle is tightened so that its end wall is in contact with the end surface of the inner nozzle body, a mist-like water sprinkling state is created, and the cap nozzle is tightened so that the end wall of the nozzle comes into contact with the end surface of the inner nozzle body. When loosened, it can be used as a water gun to release water.

[Example] Hereinafter, an example of this invention will be described with reference to the drawings. In the figure, 1 is a handle-shaped water tank equipped with a removable water filling cap 2, and 3 is a handle-shaped water tank that fits into the upper front side protrusion 4 of the water tank 1. 5 is a water suction tube that is connected to the inwardly protruding port 6 of the outer pipe holder 3 via a joint pipe 7 and is curved and suspended in the water tank 1; 8 is a water suction tube of the outer pipe holder 3; 8a is an outer pipe with a diameter of about 1 cm and a length of, for example, about 14 cm, with one end inserted and fixed into the outward protrusion port 9 and protruding long forward of the water tank 1.
grip stop spring fitted and fixed on the tip of the
Reference numeral 10 denotes an inner pipe that is slidably inserted into the outer pipe 8, and 11 has a communication hole 12 in the center and an O-ring 13 on the outer periphery, and is inserted and fixed into the inner end of the inner pipe 10. A perforated piston 14 has one end inserted and fixed into the distal end of the inner pipe 10 and extends coaxially, and 15 has two water fountain holes 16 and 17 passing through in the axial direction, and a piston 15 that extends between the two water fountain holes 16 and 17. An inner nozzle body having a communicating end groove 18 and an outer peripheral O-ring 19 and fitted into the inner hole 20 at the tip of the grip tube 14; 21 is an end wall portion that comes into contact with and separates from the tip surface of the inner nozzle body 15; 22 and an outer cap nozzle 25 for switching between water sprinkling and water discharge, which has one nozzle hole 23 provided at the center of this end wall and is screwed onto the threaded end portion 24 of the grip tube 14 as shown in FIG. ，
26 is the inside of the outer pipe holder 3 and the grip tube 1
These are a pair of check valves built into the tip inner hole portion 20 of No. 4.

Note that this one check valve 25 (tank side check valve) is formed as a one-way valve that closes when the piston 11 moves backward and opens when the piston 11 moves forward, and the other check valve 25 (tank side check valve) is formed as a one-way valve that closes when the piston 11 moves backward and opens when the piston 11 moves forward. The check valve 26 is formed as a one-way valve that opens when the piston 11 moves backward and closes when the piston 11 moves forward.

Then, fill the water tank 1 with water, hold the water tank 1 with one hand, and use the other hand to hold the grip tube 1.
4 and perform a pulling operation so that the inner and outer pipes 10 and 8 extend, the forward movement of the perforated piston 11 opens the check valve 25 on the water tank 1 side, and the check valve on the nozzle 21 side opens. 26 is closed, and the water W in the water tank 1 is sucked into the outer and inner pipes 8, 10 and the grip pipe 14 via the water suction tube 5.

Next, when the inner pipe 10 is pushed into the outer pipe 8 so that the inner and outer pipes 10 and 8 are contracted, the tank side check valve 25 closes due to the backward movement of the perforated piston 11, and the nozzle side check valve 26 closes. When the valve is opened, the water injected into the inner and outer pipes 10, 8 and the grip pipe 14 is discharged from the tip nozzle hole 23. At this time, if the outer cap nozzle 21 is tightened so as to come into contact with the end surface of the inner nozzle body 15, a mist-like water sprinkling state will occur. If it is, it will be possible to fire water as a water gun.

[Effect of the invention] Since the water gun toy of this invention has the above-mentioned structure, it does not require the troublesome water absorption operation as in the past, and can be easily done by simply pushing and pulling the grip tube to expand and contract the inner and outer pipes. Even with simple operations, the water in the tank can be sucked up and released over and over again.

Moreover, if the tip nozzle structure is composed of the inner nozzle body and outer cap nozzle as described above,
By tightening or loosening this outer cap nozzle, it is possible to switch between spraying water in the form of a mist and discharging water from a water gun.
