Description

Toy water cannon gun

Technical Field

The utility model belongs to the technical field of the toy squirt, in particular to toy squirt gun.

Background

The child water gun indirectly utilizes tap water pressure and exerts external force on the basis, so that the water pressure in the rubber tube in the water gun can be higher than the tap water pressure, the water gun can spray water at a long range, and the safety is stronger than that of a solid bullet gun. Common water guns all use water as bullets, and shoot by pressurizing, the shooting effect is single line or multiple lines, and the shooting effect is single.

The main working principles of the water gun are as follows:

the first method comprises the following steps: as shown in FIG. 1, the syringe type single shot type uses water as a bullet, and the trigger is pulled to pressurize a single shot, and the pressurized shot linear water bullet is decompressed, and when the trigger is reset, the shooting is stopped, and the process is repeated. The working process is as follows: adding water into a water storage container E, pulling a trigger A to compress a spring B and push a piston C to pressurize the water storage container E through a one-way valve D, and extruding the water out through a water pipe F through a pinhole gun mouth G under the pressure; when the trigger A is released, the spring B resets the trigger A, the piston C resets to suck air, and the check valve D prevents water and air in the water storage container E from flowing back. Trigger a is again pulled to repeat this. The advantages are that: the size is small and the cost is low; the disadvantages are as follows: the water storage container is small, the shooting distance is short, and only point shooting can be performed.

And the second method comprises the following steps: as shown in FIG. 2, the accumulator continuous shooting type uses water as a bullet and has an independent pressurizing device, and the pressurizing device pressurizes for many times and then triggers a trigger to shoot, so that continuous linear shooting can be realized. The working process is as follows: adding water into the water storage and pressure accumulation container E, moving the pressurizing rod A in a reciprocating mode, pushing the piston C to pressurize the water storage and pressure accumulation container E through the one-way valve D, closing the gate valve F in the pressurizing process, preventing water and air from flowing back to the piston C through the one-way valve D, pulling the trigger B to open the gate valve F after pressurization is completed, continuously extruding the water in a linear mode through the water pipe G through the pinhole muzzle H, and shooting until the internal and external pressures of the water storage and pressure accumulation container E are balanced to finish shooting, so that the reciprocating mode is achieved. The advantages are that: the water storage container is large, the shooting distance is long, and continuous shooting can be realized; the disadvantages are as follows: linear shooting and small water flow.

Detailed Description

The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.

As shown in fig. 3, a toy water cannon gun comprising: a pressurizing device 1, a pressure container 2, a water storage container 3, a gun barrel 4 and a trigger 5.

Wherein the pressurizing device 1 comprises an air pump and a first one-way valve 11.

The air pump comprises a cylinder 14, a piston 13 and a pressurizing rod 12, wherein the piston 13 is provided with a concave rubber bowl, and the pressurizing rod 12 is fixedly connected with the piston 13.

The pressure container 2 is provided with a first input port 21 and an output port 22, and the first input port 21 is connected with the air pump through the first one-way valve 11.

The water storage container 3 is used for storing liquid water, and the lower end of the water storage container is provided with a second one-way valve 31.

The diameter of the gun barrel 4 is 1 cm-5 cm. The gun barrel 4 is provided with a water bullet bin 41, a second input port 42 and a water spraying port 43, wherein the second input port 42 is connected with the output port 22 of the pressure container 2; be equipped with water magazine 41 on the gun barrel 4, water container 3 passes through second check valve 31 fixed connection be in the top of water magazine 41, the both ends of water magazine 41 all are equipped with check valve 44, water magazine 41 with be equipped with gate valve 45 between the second input port 42. The trigger 5 is connected to the gate valve 45 and is used for controlling the opening and closing of the gate valve 45.

The check valve 44 includes a valve seat 441, a valve core 442 and a blocking piece 443, the valve seat 441 is fixed on the inner side of the barrel 4, the valve core 442 is connected with the valve seat 441 through an elastic member 444, the blocking piece 443 is centrally provided with a counter bore matched with the valve core 442, and the valve core 442 sinks into the counter bore under the elastic force of the elastic member 444. The elastic member 444 is a spring.

The blocking pieces 443 of the check valves 44 at both ends of the water magazine 41 are disposed at a side close to the second input port 42. The spool 442 of the check valve 44 has a spring but is not so resilient as to prevent the water in the cartridge 41 from flowing out when not in a shot state. Because the water in the water magazine 41 is at atmospheric pressure, the pressure on the check valve 44 is small. The right check valve 44 prevents water from flowing into the pressure vessel 2 by opening the gate valve 45 by pulling the trigger when the pressure vessel 2 is at normal pressure (non-pressurized state).

The pipe diameter of the water gun barrel 4 is thicker, and meanwhile, the diameter of the check valve 44 is also thicker, so that the stress area is larger, and the high-pressure air can push water to pass through very quickly, and finally the spraying effect can be achieved.

After pressurizing the pressure vessel 2, the trigger is triggered to open the gate valve 45, the air pressure in the pressure vessel 2 is far greater than the water pressure of the water magazine 41 and the spring resistance of the valve core 442 of the check valve 44, the water amount in the water magazine 41 is small, the water can be instantly and quickly sprayed out of the water spraying port 43 of the gun barrel 4 by high-pressure air, the water cannot flow back, and the kinetic energy for spraying out the water is derived from the high-pressure air in the pressure vessel 2.

The working process is as follows: adding water into the water storage container 3, supplementing water to the water magazine 41 through the second one-way valve 31, stopping water leakage from the check valve 44 to the gun barrel 4 and the pressure container 2, moving the pressurizing rod 12 in a reciprocating mode, pushing the piston 13 to pressurize the pressure container 2 through the first one-way valve 11, stopping air leakage from the pressure container 2 to the piston 13 side through the first one-way valve 11, turning on a trigger after pressurization is completed, pushing high-pressure air in the pressure container 2 to push the right check valve 44 away instantly, pushing water in the water magazine 41 to jet out through the gun barrel 4 through the left check valve 44, closing the second one-way valve 31 by high-pressure water gas in the water magazine 41 during shooting, preventing water from flowing back to the water storage container 3, and completing shooting. The water storage container 3 continues to add water to the water magazine 41, and moves the pressurizing rod 12 to pressurize, thereby reciprocating. The operation is simple, and the suitable age group is wide; simple structure and low production cost.
