[0024] Please refer to Figures 1-6The embodiment provides a durable toy water spraying mechanism, which comprises a shell 1, a launching barrel 2 fixed to one end of the shell 1, a motor 3 fixed in the shell 1, a tail top 4 fixed to the other end of the shell 1 relative to the launching barrel 2, and a piston rod 5 capable of reciprocating in the launching barrel 2 under the action of elasticity and the power of the motor 3, wherein the piston rod 5 is elastically connected to the shell 1 through a spring (not shown in the figure), and the piston rod 5 is drivingly connected to the output end of the motor 3 through a gear set 6.

[0025] The shell 1 comprises a first shell 11 and a second shell 12 which are detachably fixed, and meanwhile, the shell 1 is provided with a switch groove 13 at a position corresponding to a trigger, and an electric control switch 7 is clamped and fixed in the switch groove 13. It can be understood that the electric control switch 7 is electrically connected with the motor 3 and is used for controlling the motor 3 to start or stop. In the embodiment, the first shell 11 and the second shell 12 are oppositely provided with limiting holes 14, each limiting hole 14 extends along the front-rear direction of the shell 1, and each limiting hole 14 movably connects the piston rod 5, so as to limit the moving direction and distance of the piston rod 5, and plays a role of improving the moving stability of the piston rod 5. In other embodiments, the limiting holes 14 can be adjusted to limiting grooves, limiting horizontal strips or other structures capable of playing a role of limiting and stable connection according to requirements, and the first shell 11 and the second shell 12 can not be provided with the limiting holes 14.

[0026] In the embodiment, the launching barrel 2 comprises a barrel body 21, a water inlet joint 22 and a water jet joint 23. The barrel body 21 is provided with an inner cavity 211 for movably connecting the piston rod 5, the side end of the barrel body 21 is provided with a water inlet pipeline 212 which is in communication with the inner cavity 211, and the front end of the barrel body 21 is provided with a water outlet pipeline 213 which is in communication with the inner cavity 211. The water inlet pipeline 212 is sequentially provided with a first sealing ring 24 and a first water passing step 25 along the water inlet direction, and a first light weight block 26 is movably installed between the first sealing ring 24 and the first water passing step 25. The water outlet pipeline 213 is sequentially provided with a second sealing ring 27 and a second water passing step 28 along the water outlet direction, and a second light weight block 29 is movably installed between the second sealing ring 27 and the second water passing step 28.

It can be understood that the water inlet joint 22 is used for connecting an external water tank, so that the water source in the external water tank can enter the water inlet joint 22, the water inlet pipeline 212 and the inner cavity 211 in sequence. The launching port of the water jet joint 23 is exposed on the shell 1, so that the water in the inner cavity 211 can be sequentially jetted out of the shell 1 through the water outlet pipeline 213 and the water jet joint 23. In other embodiments, the launching barrel 2 can only comprise the barrel body 21.

[0027] It should be noted that the first water passing step 25 and the second water passing step 28 are both provided as a plurality of step blocks 201 distributed at intervals, so that when the first water passing step 25 and the second water passing step 28 abut against the corresponding light weight blocks, there is still a gap between any two step blocks 201 for water flow, showing an open state of the pipeline. In the embodiment, the first water passing step 25 is located in the water inlet pipeline 212 adjacent to the inner cavity 211, and the plurality of step blocks 201 in the first water passing step 25 extend to the port of the water inlet pipeline 212 through the flow guide ribs 202, so as to play a better flow guiding role. The second water passing step 28 is located in the water jet connector 23 away from the inner cavity 211, and the plurality of step blocks 201 in the second water passing step 28 also extend to the port of the water jet connector 23 through the flow guide ribs 202, so as to also play a better flow guiding role. In other embodiments, the first water passing step 25 and / or the second water passing step 28 can not be provided with flow guide ribs 202.

[0028] It should be noted that in the embodiment, the first light weight block 26 and the second light weight block 29 are both solid spherical structures, and the outer surfaces of the solid spherical structures are smooth arc surfaces, which is beneficial to reduce water flow resistance and ensure that water can flow at a faster flow rate. The first light weight block 26 and the second light weight block 29 can be made of light weight materials such as foam materials, rubber materials, plastic materials or wooden materials, so that when the air pressure in the inner cavity 211 changes due to the movement of the piston rod 5, the first light weight block 26 and the second light weight block 29 can be relatively easily forced to move outward or inward at the same time. In other embodiments, the first light weight block 26 and the second light weight block 29 can also be other polyhedrons or cylinders, and the first light weight block 26 and the second light weight block 29 can also adopt a hollow structure.

[0029] The motor 3 is controlled to start by the electric control switch 7, and is used to provide driving force for the movement of the piston rod 5.

[0030] The spring of the piston rod 5 is sleeved on the tail top 4, so that the spring is not easy to be forced to displace. The spring is used to store energy when being extruded by the piston rod 5, so that the spring can drive the piston rod 5 to move reversely when the piston rod 5 is separated from the gear set 6.

[0031] The piston rod 5 comprises an integral connecting section 51 and a piston section 52, wherein the connecting section 51 abuts one end of the spring, the connecting section 51 is outwardly convex with a connecting block 511 opposite to the side wall of the limiting hole 14, and the connecting block 511 is movably connected in the limiting hole 14. The connecting section 51 is further provided with a gear rack 512, which is drivingly connected to the output end of the motor 3 through the gear set 6. The piston section 52 is respectively connected with a third sealing ring 521 and a gasket 522 at both ends, the third sealing ring 521 movably abuts the cavity wall of the inner cavity 211 to form a sealed space in the inner cavity 211, and the gasket 522 is abuttingly connected with the end wall of the launching barrel 2 to buffer the impact force.

[0032] In the embodiment, the gear set 6 comprises six gears connected in sequence, one of the terminal gears of the gear set 6 is fixed on the output end of the motor 3, and the other terminal gear of the gear set 6 is provided with a toothless gear part 61, which is separably meshingly connected with the gear rack 512. In the process of continuous rotation of the motor 3, the gear set 6 can continuously act the driving force on the piston rod 5 through the cooperation of the toothless gear part 61 and the gear rack 512, and since the toothless gear part 61 is separably connected with the gear rack 512, the toothless gear part 61 and the spring can cooperate to drive the piston rod 5 to reciprocate between the launching barrel 2 and the tail fin 4. In other embodiments, the gear set 6 can be provided as other number of gear chain structures, for example, the gear set 6 can be composed of five gears, four gears, three gears and the like connected in sequence.

[0033] It should be noted that when the piston rod 5 moves outwardly from the inner cavity 211 under the power of the motor 3, a negative pressure is formed in the inner cavity 211, the first lightweight block 26 and the second lightweight block 29 are forced to move into the inner cavity 211, so that the first lightweight block 26 can abut on the first water passage step 25, and the second lightweight block 29 can abut on the second sealing ring 27 to present a state of closed pipeline, thereby realizing the function of one-way opening of the water inlet pipeline 212. When the piston rod 5 moves rapidly into the inner cavity 211 under the elastic force, the water flow in the inner cavity 211 rapidly impacts the first lightweight block 26 and the second lightweight block 29 to drive them to move outwardly from the inner cavity 211, so that the first lightweight block 26 can abut on the first sealing ring 24, and the second lightweight block 29 can abut on the second water passage step 28, thereby realizing the function of one-way opening of the water outlet passage 213, and further enabling the water flow to be shot out of the water jet connector 23 at high speed.

[0034] For the sake of clarity, some features described in separate embodiments of the present application can be combined in a single embodiment. Moreover, various features of the present application described in a single embodiment can also be used in separate or in any suitable form in sub-combinations.
