[0016] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The self-luminous toy water gun involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0017] Reference Figures 1 to 4 This utility model provides a self-illuminating toy water gun, including an outer sleeve assembly 1 and a movable, push-pullable lever assembly 2 disposed within the outer sleeve assembly. The outer sleeve assembly 1 includes a pearl cotton protective sleeve 21 and an outer cylinder 22, which are fixedly connected from the outside to the inside. The front end of the outer sleeve assembly 1 is a water outlet. From the water outlet to the lever assembly, an outer end cap 24, a shower head cap 25, a spray end cap 26, a flange 29, a fan blade end cap 30, and a water-holding pipe 23 are fixedly connected sequentially on the inner side of the outer cylinder. A generator 27 and an LED light 271 are installed on one side of the flange 29, and a drive impeller 28 connected to the input shaft of the generator 27 is installed on the other side of the flange 29. The lever assembly 2 includes a piston rod 201 movably disposed within the water-holding pipe 23 and a piston sleeve 202 fixedly connected to the front end of the piston rod. A sealing ring 203 is installed on the piston sleeve 202. The lever assembly 2 can be manually pushed and pulled to move back and forth within the water-holding pipe 23.
[0018] The outer end cap 24 has a through hole in the center, which allows water to spray outward from the through hole when the pull rod assembly 2 is pushed forward, forming a high-pressure water column.
[0019] The shower head cover 25 has multiple closely spaced small holes to facilitate water flow.
[0020] The side wall of the fan blade end cover 30 is provided with a water inlet hole 31, so that when the pull rod assembly 2 is pushed forward, water flows from the water pipe 23 into the inside of the fan blade end cover 30 through the water inlet hole 31, driving the impeller 28 to rotate.
[0021] The flange 29 has water guide holes 291 on both sides, which facilitates the water flow to continue forward after passing through the drive impeller 28, and finally be ejected from the central through hole of the outer end cover 24 after passing through the shower cover 25.
[0022] The aforementioned "fixed connection" generally uses glue to fix the various parts together. In some cases, tight fitting or threads can also be used for fixed connection.
[0023] The generator 27 and LED light 271 are both coated with a waterproof adhesive layer on the outside, which is existing technology and its working principle will not be described in detail here.
[0024] The working principle of this utility model is as follows:
[0025] 1. When the pull rod assembly 2 is pushed forward, water flows from the water pipe 23 through the water inlet hole 31 on the side wall of the fan blade end cover into the inside of the fan blade end cover 30, driving the impeller 28 to rotate.
[0026] 2. The impeller 28 drives the input shaft and magnet of the generator to rotate, cutting the coil inside the generator and generating induced current.
[0027] 3. The induced current drives the LED lamp 271 to emit light, producing a light-emitting effect.
[0028] 4. The water gun is fully covered with a soft pearl cotton protective layer to ensure the safety of children when they hit each other while playing.
[0029] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
