TECHNICAL FIELD

The present invention relates to a water spray structure and pertains to the technical field of toy products.

BACKGROUND

A toy water gun is a type of toy gun that can be filled with water and shoots out water streams. In comparison to toy guns that shoot solid projectiles, water guns are safer as they utilize water as ammunition. Most toy water guns currently available are designed to utilize tap water pressure and external force to increase the water pressure inside a rubber tube within the toy gun. This design allows the water pressure to surpass that of tap water, resulting in a longer shooting range and creating a more exhilarating and enjoyable experience for users. Moreover, water guns contribute to cognitive development of children, particularly during group games where they foster teamwork and enhance emotional intelligence among children and their companions. It is no surprise that water guns have become highly coveted toys for children, with many longing to possess a large water gun. However, traditional toy water guns have drawbacks such as requiring users to manually squeeze a water storage chamber inside the gun with their fingers, resulting in a slow shooting rate and potential discomfort and soreness in the fingers after prolonged use due to the release of only one water stream with each squeeze.

SUMMARY

An objective of one embodiment of the present invention is to provide a water spray structure of a continuous shooting toy water gun, which addresses the problem in the prior art that traditional toy water guns require users to manually squeeze a water storage chamber inside the gun with their fingers, resulting in a slow shooting rate and potential discomfort and soreness in the fingers after prolonged use due to the release of only one water stream with each squeeze.

The objective of the present invention can be achieved by the following technical solution. In an embodiment of the present invention, a water spray structure of a continuous shooting toy water gun with a water storage chamber, comprises:

• • a housing;
  • a water spray chamber, provided at a front end of the housing;
  • a rear end of the water spray chamber, the rear end of the water spray chamber being fixedly connected to the front end of the housing to form an integral unit;
  • a nozzle provided at a front end of the water spray chamber;
  • a water inlet provided at a bottom surface of the water spray chamber, the bottom surface of the water spray chamber being connected to the water storage chamber by the water inlet;
  • a piston positioned inside the water spray chamber;
  • an electric motor installed at a rear end of the housing;
  • a swinging mechanism; and
  • a driving mechanism connected to a motor shaft of the electric motor and thereby drives the piston through the swinging mechanism.

Further, the driving mechanism comprises a motor gear, a driving gear assembly, and a transition gear assembly; the motor gear is coaxially and fixedly sleeved and mounted on the motor shaft of the electric motor, the transition gear assembly and the driving gear assembly are sequentially arranged inside the housing from front to rear, the motor gear is connected to the driving gear assembly, the driving gear assembly is connected to the transition gear assembly, and the transition gear assembly is meshed with the swinging mechanism.

Further, the driving gear assembly comprises a first gear and a second gear which are coaxially and fixedly connected, the first gear being engaged with the motor gear, and the second gear being meshed with the transition gear assembly.

Further, wherein the transition gear assembly comprises a third gear and a fourth gear which are coaxially and fixedly connected, the third gear being engaged with the second gear, and the fourth gear being meshed with the swinging mechanism.

Further, the swinging mechanism comprises a swing rod and a swing rod driving gear, the swing rod driving gear being pivotally connected to an inner shaft of the housing and engaged with the fourth gear, and the swing rod being pivotally connected at a rear end to an edge of the swing rod driving gear and pivotally connected at a front end to the piston.

Compared to the prior art, the present invention has the following advantages: 1. By utilizing an electric motor to drive the piston in a reciprocating motion within the water spray chamber, the present invention enables continuous shooting of water streams from the water gun. As a result, users only need to press down a trigger of the water gun to shoot water streams continuously, eliminating the potential discomfort and soreness in the fingers that may occur with prolonged use of traditional toy water guns.

2. The present invention achieves reciprocating motion of the piston through a combined driving method that combines continuous gear driving and swing rod driving. This not only ensures high transmission reliability but also provides a simple structure, making it convenient for replacement and maintenance purposes.

Working Principle

The electric motor 4 drives the motor gear 5 to rotate, the motor gear 5 in turn rotates the first gear 6. The second gear 7, which rotates coaxially with the first gear 6, causes the third gear 8 to rotate. The fourth gear 9, rotating coaxially with the third gear 8, causes the swing rod driving gear 11 to rotate. The rotation of the swing rod driving gear 11 transfers force through the swing rod 10 to the piston 3, resulting in reciprocating motion of the piston 3 inside the water spray chamber 2. When the piston 3 moves backward in the water spray chamber 2, a negative pressure is created, drawing water from the water storage chamber of the water gun through the water inlet 202 into the water spray chamber 2. Conversely, when the piston 3 moves forward, a positive pressure is generated, expelling the water from the water spray chamber 2 through the nozzle 201. Through continuous reciprocating motion of the piston 3 within the water spray chamber 2, water is continuously drawn from the water storage chamber and shot out through the nozzle 201, realizing continuous shooting of water streams.
