Description

Technical Field

[0001] This invention relates to an amusement device, and more particularly to an amusement water cannon. Background Technology

[0002] A water cannon is an amusement device that uses water as "ammunition." It consists of a cannon barrel and a support column. The barrel is supported on the column, and a high-pressure cylinder is connected to the rear end of the barrel. The high-pressure cylinder is connected to the inside of the barrel via a pipe, the flow of which is controlled by a solenoid valve. To use it, water is first filled into the barrel, then a switch is pressed to energize the solenoid, connecting the pipe. High-pressure gas from the cylinder quickly enters the barrel, causing the water to spray out. This type of water cannon can also launch balls. The ball is placed inside the water-filled barrel, and the sprayed water propels the ball out. However, this type of water cannon requires water to be added to the barrel before each launch, therefore it cannot fire continuously or at any time, and the water spray is diffused rather than concentrated.

[0003] Patent application CN115645939A discloses another type of amusement water cannon, which includes a cannon barrel, a support base, and a pressing device. The cannon barrel is supported on the support base, and the pressing device is connected to the rear end of the cannon barrel via a connecting pipe to provide high-pressure water flow to the cannon barrel. In use, a ball is inserted into the cannon barrel, and pulling the movable plug allows the high-pressure water flow from the pressing device to enter the cannon barrel, launching the ball out. This type of water cannon uses a pressing device connected to the rear end of the cannon barrel, allowing for continuous and timely high-pressure water flow; however, the water emitted from the cannon barrel is still diffused and cannot form a jet. Summary of the Invention

[0004] The purpose of this invention is to provide a water cannon for recreational use, which uses water as projectiles and can be fired continuously and at any time, and the water that is fired can be bundled together and not scattered.

[0005] The amusement water cannon of the present invention includes a cannon barrel and a support column. The cannon barrel is supported on the support column. It also includes a water pump, a water spray pipe, a water inlet pipe, a water blocking device, and a driving device. The water spray pipe is located inside the cannon barrel and parallel to the cannon barrel, with its spray nozzle facing the cannon barrel opening. One end of the water inlet pipe is connected to the water inlet of the water spray pipe, and the other end extends out of the cannon barrel and is connected to the water pump. The water blocking device and the driving device are located inside the cannon barrel. Under the action of the driving device, the water blocking device is activated to expose the spray nozzle of the water spray pipe, so that the water sprayed from the water spray pipe is sprayed out of the cannon barrel, or to block the spray nozzle of the water spray pipe, so that the water sprayed from the water spray pipe flows back to the water source. The water-blocking device is a U-shaped water-blocking pipe, with its outlet end rotatably supported inside the barrel. A return spring is connected between the water-blocking pipe and the inner wall of the barrel. A limit block is provided on the inner wall of the barrel. When not in operation, under the action of the return spring, the water-blocking pipe abuts against the limit block, and its inlet end is located directly in front of the nozzle of the spray pipe, blocking the nozzle of the spray pipe. The driving device includes a first electromagnet and a second electromagnet. The first electromagnet is set on the water-blocking pipe near the inlet end of the water-blocking pipe, and the second electromagnet is set on the inner wall of the barrel. The first electromagnet and the second electromagnet are positioned opposite each other. When they are energized, the first electromagnet and the second electromagnet attract each other, causing the water-blocking pipe to rotate against the force of the return spring, thus exposing the nozzle of the spray pipe.

[0006] The amusement water cannon of the present invention includes a cannon barrel and a support column. The cannon barrel is supported on the support column. It also includes a water pump, a water spray pipe, a water inlet pipe, a water blocking device, and a driving device. The water spray pipe is located inside the cannon barrel and parallel to the cannon barrel, with its spray nozzle facing the cannon barrel opening. One end of the water inlet pipe is connected to the water inlet of the water spray pipe, and the other end extends out of the cannon barrel and is connected to the water pump. The water blocking device and the driving device are located inside the cannon barrel. Under the action of the driving device, the water blocking device is activated to expose the spray nozzle of the water spray pipe, so that the water sprayed from the water spray pipe is sprayed out of the cannon barrel, or to block the spray nozzle of the water spray pipe, so that the water sprayed from the water spray pipe flows back to the water source. The water-blocking device is a U-shaped water-blocking pipe, with its outlet end rotatably supported inside the barrel. The driving device includes a pneumatic cylinder, the piston rod of which is hinged to the water inlet end of the water-blocking pipe near the water-blocking pipe. The cylinder body of the pneumatic cylinder is hinged to the inner wall of the barrel. When the piston rod is extended, the water inlet end of the water-blocking pipe is located directly in front of the nozzle of the water spray pipe, blocking the nozzle of the water spray pipe. When the piston rod retracts, it causes the water-blocking pipe to rotate, exposing the nozzle of the water spray pipe.

[0007] It also includes a return water pipe installed and fixed inside the barrel, wherein the outlet end of the water baffle pipe is inserted into the inlet end of the return water pipe and rotates to engage with the inlet end of the return water pipe, and the outlet end of the return water pipe extends out from inside the barrel.

[0008] The support column is a hollow cylindrical structure, and its interior is connected to the inside of the gun barrel. The other end of the water inlet pipe passes through the inside of the gun barrel, through the inside of the support column, and then through the bottom of the support column to connect with the water pump.

[0009] The outlet end of the return water pipe extends out of the barrel and connects to the inside of the support column.

[0010] A flange is provided at the inlet end of the return water pipe, and a countersunk hole is provided on its end face. A step is provided at the outlet end of the baffle pipe. The outlet end of the baffle pipe is rotatably supported in the inlet end of the return water pipe by a bearing. The step is located in the countersunk hole. A retaining ring is fitted on the baffle pipe, and the retaining ring is fixed to the flange by bolts.

[0011] In use, connect the inside of the support column to the water source, connect the water pump inlet to the water source, and start the water pump. High-pressure water flows into the spray pipe through the inlet pipe and is ejected from the nozzle of the spray pipe. When the electromagnet is not energized or the pneumatic cylinder is not activated, the inlet of the baffle pipe is located directly in front of the nozzle of the spray pipe, blocking the nozzle. The water flow from the nozzle of the spray pipe will enter the baffle pipe and flow back to the water source through the return pipe and the inside of the support column. At this time, no water jet is fired from the water cannon. To fire, press the switch to energize the electromagnet or activate the pneumatic cylinder. The baffle pipe rotates relative to the return pipe, exposing the nozzle of the spray pipe, and a jet of water is then fired from the barrel.

[0012] The water cannon of this invention sprays water jets powered by a water pump. The water jets are actually ejected from the spray pipe inside the cannon barrel, thus ensuring that the water is sprayed in a concentrated stream rather than scattering. Because a water-blocking device is installed inside the cannon barrel, the water jet launch can be controlled by obstructing or exposing the spray nozzle. The action of the water-blocking device is controlled by a drive mechanism. Although the water flow is constantly spraying under the action of the water pump, the operator can control the launch of the water jet by manipulating the drive mechanism. Therefore, a concentrated water jet can be launched continuously and at any time. When not launching, the water flow returns from inside the cannon barrel to the water source, preventing water waste.

[0013] This invention uses water as projectiles, enabling the continuous and high-frequency cutting and restoration of the ejected water flow. During the high-frequency cutting and restoration process, the water flow can be cut off instantly and completely, and the water pressure, velocity, and flow rate can be restored immediately. The ejected water is concentrated in a bundle and does not diverge, thus simulating the scenario of firing a single projectile and firing a series of projectiles at high speed. It is simple and convenient to operate and full of fun. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0021] Implementation Method 1:

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the amusement water cannon includes a cannon barrel 1, a support column 8, a water spray pipe 2, a water inlet pipe 5, a water baffle pipe 10, a water return pipe 9, a water pump 7, and a chassis frame 6. The support column 8 is a hollow cylindrical structure, and the cannon barrel 1 is supported on the support column 8. The interior of the cannon barrel 1 is connected to the interior of the support column 8, and the support column 8 is rotatably supported on the chassis frame 6. The water spray pipe 2 is located inside the cannon barrel 1 and parallel to the cannon barrel 1, with its spray nozzle facing the cannon barrel opening. One end of the water inlet pipe 5 is connected to the water inlet of the water spray pipe 2, and the other end passes through the cannon barrel 1, through the interior of the support column 8, and then through the bottom of the support column 8 to connect with the water pump 7. The water return pipe 9 is installed and fixed inside the cannon barrel 1 by a bracket connected to the inner wall of the cannon barrel 1. The outlet end of the water return pipe 9 passes through the cannon barrel 1 and connects to the interior of the support column 8. The water-blocking pipe 10 is U-shaped and located inside the barrel 1. Its outlet end is inserted into the inlet end of the return water pipe 9 and rotates to engage with the inlet end of the return water pipe 9. Figure 6 As shown, a flange 91 is provided at the inlet end of the return water pipe 9, and a countersunk hole 92 is provided on its end face. A step 101 is provided at the outlet end of the baffle pipe 10. The outlet end of the baffle pipe 10 is rotatably supported in the inlet end of the return water pipe 9 by a bearing 19. At the same time, the step 101 is located in the countersunk hole 92. A retaining ring 13 is fitted on the baffle pipe, and the retaining ring 13 is fixed to the flange 91 by bolts 18, thereby axially restricting the outlet end of the baffle pipe 10, so that it can only rotate relative to the return water pipe 9 and cannot move axially. A return spring 15 is connected between the baffle pipe 10 and the inner wall of the barrel 1. The return spring 15 is a tension spring. A limit block 14 is provided on the inner wall of the barrel 1. When not in operation, under the action of the return spring 15, the baffle pipe 10 abuts against the limit block 14, and its inlet end is located in front of the nozzle of the spray pipe 2, blocking the nozzle of the spray pipe 2.

[0023] A first electromagnet 11 is installed on the water-blocking pipe 10 near the water inlet end of the water-blocking pipe 10, and a second electromagnet 12 is installed on the inner wall of the cannon barrel 1. The first electromagnet 11 and the second electromagnet 12 are positioned opposite each other. The first electromagnet 11 and the second electromagnet 12 are connected in the control circuit of the electromagnet. The switch 4 of the electromagnet control circuit is installed on the water cannon handle 3. When the first electromagnet 11 and the second electromagnet 12 are energized, the first electromagnet 11 and the second electromagnet 12 attract each other, causing the water-blocking pipe 10 to overcome the return spring force and rotate relative to the return water pipe 9, thus exposing the spray nozzle of the spray pipe 2.

[0024] In use, connect the inside of the support column 8 to the water source, connect the inlet of the water pump 7 to the water source, start the water pump 7, and high-pressure water flows into the spray pipe 2 through the inlet pipe 5 and sprays out from the nozzle of the spray pipe 2. When the first electromagnet 11 and the second electromagnet 12 are not energized, the inlet of the baffle pipe 10 is located directly in front of the nozzle of the spray pipe 2, blocking the nozzle of the spray pipe 2. The water flow sprayed from the nozzle of the spray pipe 2 will enter the baffle pipe 10 and flow back to the water source through the return pipe 9 and the inside of the support column 8. At this time, no water jet is fired from the water cannon. When firing, press the switch 4 to energize the first electromagnet 11 and the second electromagnet 12. The baffle pipe 10 overcomes the return spring force and rotates relative to the return pipe 9, exposing the nozzle of the spray pipe 2. Then, a jet of water is fired from the barrel 1. When switch 4 is pressed again, the first electromagnet 11 and the second electromagnet 12 are de-energized, the water-blocking pipe 10 returns to its original position under the action of the return spring 15, and the water nozzle of the water spray pipe 2 is blocked again. The water cannon no longer shoots out water, and the water sprayed out by the water spray pipe 2 enters the water-blocking pipe 10 again, and flows back to the water source through the return pipe 9 and the support column 8.

[0025] Implementation Method Two:

[0026] like Figure 1 , Figure 4 and Figure 5 As shown, the amusement water cannon includes a cannon barrel 1, a support column 8, a water spray pipe 2, a water inlet pipe 5, a water baffle pipe 10, a water return pipe 9, a water pump 7, and a chassis frame 6. The support column 8 is a hollow cylindrical structure, and the cannon barrel 1 is supported on the support column 8. The interior of the cannon barrel 1 is connected to the interior of the support column 8, and the support column 8 is rotatably supported on the chassis frame 6. The water spray pipe 2 is located inside the cannon barrel 1 and parallel to the cannon barrel 1, with its spray nozzle facing the cannon barrel opening. One end of the water inlet pipe 5 is connected to the water inlet of the water spray pipe 2, and the other end passes through the cannon barrel 1, through the interior of the support column 8, and then through the bottom of the support column 8 to connect with the water pump 7. The water return pipe 9 is installed and fixed inside the cannon barrel 1 by a bracket connected to the inner wall of the cannon barrel 1. The outlet end of the water return pipe 9 passes through the cannon barrel 1 and connects to the interior of the support column 8. The water-blocking pipe 10 is U-shaped and located inside the barrel 1. Its outlet end is inserted into the inlet end of the return water pipe 9 and rotates to engage with the inlet end of the return water pipe 9. Figure 6 As shown, a flange 91 is provided at the inlet end of the return water pipe 9, and a countersunk hole 92 is provided on its end face. A step 101 is provided at the outlet end of the baffle pipe 10. The outlet end of the baffle pipe 10 is rotatably supported in the inlet end of the return water pipe 9 by a bearing 19. At the same time, the step 101 is located in the countersunk hole 92. A retaining ring 13 is fitted on the baffle pipe. The retaining ring 13 is fixed to the flange 91 by bolts 18, thereby axially restricting the outlet end of the baffle pipe 10, so that it can only rotate relative to the return water pipe 9 and cannot move axially. A pneumatic cylinder is installed inside the barrel 1. The pneumatic cylinder is controlled by a control air circuit. The switch 4 of the control air circuit is located on the handle 3. The piston rod 16 of the pneumatic cylinder is hinged to the water inlet end of the water baffle pipe 10 near the water inlet end of the water baffle pipe 10. The cylinder body 17 of the pneumatic cylinder is hinged to the inner wall of the barrel 1. When the piston rod 16 is in the extended state, the water inlet end of the water baffle pipe 10 is located in front of the water nozzle of the water spray pipe 2, blocking the water nozzle of the water spray pipe 2. When the piston rod 16 is retracted, the water baffle pipe 10 rotates relative to the return water pipe 9, exposing the water nozzle of the water spray pipe 2.

[0027] In use, connect the inside of the support column 8 to the water source, connect the inlet of the water pump 7 to the water source, and start the water pump 7. High-pressure water flows into the spray pipe 2 through the inlet pipe 5 and is sprayed out from the nozzle of the spray pipe 2. When the pneumatic cylinder is not activated, the piston rod 16 is in the extended state, and the inlet of the baffle pipe 10 is located directly in front of the nozzle of the spray pipe 2, blocking the nozzle of the spray pipe 2. The water flow sprayed from the nozzle of the spray pipe 2 will enter the baffle pipe 10 and flow back to the water source through the return pipe 9 and the inside of the support column 8. At this time, no water jet is fired from the water cannon. When firing, press the switch 4 to activate the pneumatic cylinder, retract the piston rod 16, and the baffle pipe 10 will rotate relative to the return pipe 9, exposing the nozzle of the spray pipe 2. Then, a jet of water is fired from the barrel 1. When switch 4 is pressed again, piston rod 16 extends and water baffle 10 returns to its original position, blocking the nozzle of water spray pipe 2 again. No water jet is ejected from the water cannon, and the water sprayed from water spray pipe 2 enters water baffle 10 again, and flows back to the water source through return pipe 9 and support column 8.
