In this embodiment, the launch canister 10 is substantially in a "T" shape, and includes an inner cavity 11, a water inlet 12 and a water outlet 13 respectively communicated with the inner cavity 11, and a positioning section 14 disposed at a position corresponding to the water inlet 13. Wherein the inner chamber 11 is cylindrically configured to receive water and to connect a portion of the drive assembly 20. The water outlet 13 is aligned with the partial driving assembly 20, so that the partial driving assembly 20 can rapidly eject water in the inner cavity 11. A portion of the valve nozzle assembly 30 is received and connected in the positioning section 14, and a clamping groove 141 is formed in a side wall of the positioning section 14, and the clamping groove 141 is used for being buckled and connected with the portion of the valve nozzle assembly 30 so as to be detachably connected to the positioning section 14. In other embodiments of the present invention, the launch canister 10 may not be provided with the positioning section 14.

It will be appreciated that drive assembly 20 includes a motor 21, a pusher member 22, and a gear train 23 drivingly connected between motor 21 and pusher member 22.

Wherein, the pushing element 22 comprises a U-shaped head 221 and a pushing rod 222 which are integrally arranged. The U-shaped head 221 is provided with two racks 2211 and two sliders 2212, the two racks 2211 are respectively disposed on two opposite inner sidewalls of the U-shaped head 221, and the two sliders 2212 are respectively disposed on two opposite outer sidewalls of the U-shaped head 221. It should be noted that the length of two end teeth 2213 in one diagonal direction of the two racks 2211 is greater than the length of the teeth at other positions, so as to achieve the meshing connection with the partial gear set 23. In this embodiment, the end tooth 2213 of any one rack 2211 corresponds to the tooth slot on the other end of the other rack 2211, i.e. the two opposite racks 2211 are arranged in a staggered manner. In other embodiments of the present invention, the two racks 2211 may not be arranged in a staggered manner. Two sliders 2212 are slidably attached to opposite sides of the housing 40, respectively, to guide the movement of the U-shaped head 221 under the restriction of the housing 40. The pushing rod 222 is located at the closed end of the U-shaped head 221, the pushing rod 222 is hermetically connected in the inner cavity 11, and the pushing rod 222 and the water outlet 13 are located on the same straight line and can reciprocate in the inner cavity 11 along with the U-shaped head 221.

In this embodiment, the gear set 23 includes a drive tooth 231, a first tooth 232, a second tooth 233, and a third tooth 234. The driving gear 231 is provided with a gear 2311, the gear 2311 is connected between the two racks 2211, the first gear 232 is fixed on the rotating shaft of the motor 21, the second gear 233 is meshed with the first gear 232, and the third gear 234 is respectively meshed with the second gear 233 and the driving gear 231, so as to transmit the transmission torque of the motor 21 to the driving gear 231 to drive the driving gear 231 to rotate. In other embodiments of the present invention, the gear set 23 may not have the second tooth 233 and/or the third tooth 234, and the first tooth 232 may directly mesh with the driving tooth 231 to drive the rotation thereof. Or the gear set 23 may have additional gears in the gear train.

It should be noted that the gear 2311 is combined with the two end teeth 2213, so that the gear 2311 can be respectively meshed with the two racks 2211 in the process of rotating for a circle, so as to drive the U-shaped head 221 to move axially to drive the pushing rod 222 to move back and forth in the inner cavity 11. Specifically, as shown in fig. 4 and 5, since the length of the end tooth 2213 is greater than the length of the teeth at other positions, and the two end teeth 2213 are located in the diagonal direction, during the rotation of the gear lacking 2311 in one direction for one circle, the toothed portion of the gear lacking 2311 first abuts against the end tooth 2213 of one of the racks 2211, and during the continuous rotation of the gear lacking 2311, the gear lacking 2311 is meshed with the other teeth of the rack 2211 to drive the pushing element 22 to move in one direction; as the gear 2311 continues to rotate, the toothed portion of the gear 2311 abuts the end tooth 2213 of the other rack 2211 and meshes with the other teeth of the rack 2211 during the continuous rotation to drive the pushing element 22 to move in the opposite direction. And then make pushing element 22 can cooperate the outside subassembly work of drawing water of squirt, promptly draw water the subassembly and draw water when advancing inner chamber 11 with water in backward movement work, then controlled forward promotion work to shoot water for the squirt and provide power to shoot the water column.

Compared with other injection mechanisms provided with elastic pieces, the working state of the driving assembly 20 is not easily interfered by the external environment, and the stability is higher. And the pushing element 22 can be driven to move greatly by adopting the motor with the common rotating speed, so that the requirement on the performance of the motor 21 is not high, the production cost can be reduced, the moving amplitude of the pushing element 22 can be kept, and the ejection power of the water gun can be ensured.

The valve nozzle assembly 30 is used for controlling the direction of water flow, and includes a first valve nozzle 31, a second valve nozzle 32, a nozzle 33 and a water inlet pipe 34. Wherein the first valve mouth 31 is arranged corresponding to the water inlet 12 and the second valve mouth 32 is arranged corresponding to the water outlet 13. It can be understood that the first valve nozzle 31 and the second valve nozzle 32 each have a main body 301 disposed in a hollow triangular prism shape, and a slit 302 is opened at a tip end of the main body 301, wherein the slit 302 of the first valve nozzle 31 is disposed toward the inner cavity 11, and the slit 302 of the second valve nozzle 32 is disposed toward the nozzle 33. The first valve mouth 31 and the second valve mouth 32 are arranged to open the slit 302 when the inner wall of the main body 301 is stressed, i.e. the first valve mouth 31 and the second valve mouth 32 are opened when stressed and closed when the stress is removed. The nozzle 33 is connected to the launch canister 10 and has a second valve nozzle 32 interference-connected therein for tightly connecting the second valve nozzle 32 to the water outlet 13. The water inlet pipe 34 is partially received in the positioning section 14 and is connected to the locking groove 141 in a snap-fit manner, and the water inlet pipe 34 is connected to the first valve nozzle 31 in an abutting manner, so as to tightly connect the first valve nozzle 31 to the water inlet 12.

It should be noted that the water inlet pipe 34 may be connected to an external water pumping assembly, when the water pumping assembly works, water flows through the water inlet pipe 34 to the first valve nozzle 31, and at this time, the inner wall of the body 301 of the first valve nozzle 31 opens the gap 302 thereof under the impact of the water flow, so that the water flow can enter the inner cavity 11 (at this time, the pushing element 22 moves backward, and since the pushing rod 222 is connected to the inner cavity 11 in a sealing manner, the pushing element 22 moves backward to form a negative pressure in the inner cavity 11, which is more beneficial to the water flow to enter the inner cavity 11 quickly). When the pushing element 22 is pushed forward, the inner wall of the body 301 of the first valve nozzle 31 is not forced to close the gap 302, and the water column in the inner cavity 11 impacts the inner wall of the second valve nozzle 32 under the pushing action of the pushing rod 222, so that the body 301 of the second valve nozzle 32 is forced to open the gap 302, and the water column is ejected through the nozzle 33.

The casing 40 is used for connecting the launch canister 10 and the driving assembly 20 into a whole, and it is understood that two sliding grooves 41 are respectively disposed at two opposite sides in the casing 40, two sliding grooves 41 are disposed corresponding to the two sliding blocks 2212, and a sliding block 2212 is slidably connected in each sliding groove 41 for guiding the movement of the U-shaped head 221.
