Abstract
Description
Technical Field
[0001] This utility model relates to a toy water gun spraying device, and more specifically to a toy water gun spraying structure with reasonable structure and parts that are not easily damaged. Background Technology
[0002] Toy water guns, because they fire water, have low lethality and high safety, making them suitable for both adults and children, and thus gain increasing market acceptance. For example, Chinese patent document CN217465510U, entitled "Water Gun Spraying Mechanism," discloses a water gun spraying mechanism including a firing tube with an inner cavity; and a drive assembly including a motor, a pushing element, and a gear set connected to the motor and the pushing element. The pushing element includes a U-shaped head and a pushing rod. A rack is respectively provided on the inner sidewall of the U-shaped head, and the length of the two end teeth on one of the racks along a diagonal direction is greater than the length of the teeth at other positions. The pushing rod is sealed within the inner cavity. The gear set includes driving teeth with missing gears connected between the two racks. During one revolution, the missing gear meshes with both racks to drive the U-shaped head axially, causing the pushing rod to reciprocate within the inner cavity.
[0003] The applicant discovered that while the aforementioned technology avoids the use of easily rusted parts such as springs, its power conversion section employs a U-shaped head with a rack and pinion mechanism to achieve the longitudinal reciprocating motion of the U-shaped head. Due to uneven force distribution on the U-shaped head, deformation occurs. Power transmission is achieved through the meshing of the two meshing parts, but these teeth are prone to wear during use. Once the wear reaches a certain level, or the deformation of the U-shaped head accumulates to a certain extent, the U-shaped head and pinion will no longer be able to mesh properly to achieve the longitudinal reciprocating motion of the U-shaped head. Therefore, although the water gun's spray mechanism of this technology can extend its service life, its structural shortcomings determine that the power conversion section (i.e., the U-shaped head and pinion) is prone to damage, resulting in a still short service life. Moreover, the unique structure of the U-shaped head and pinion, requiring precise meshing, makes its cost high and difficult to reduce. Utility Model Content
[0004] The purpose of this invention is to provide a rationally structured toy water gun spraying structure. This rationally structured structure allows for a more efficient power conversion mechanism, reducing the likelihood of damage and effectively extending its service life. The technical solution adopted is as follows:
[0005] A reasonably structured toy water gun spraying mechanism includes a spraying structure housing, a launching tube, a pumping component, and a reciprocating pumping mechanism. The launching tube and the reciprocating pumping mechanism are respectively installed inside the spraying structure housing. The pumping component is characterized by being composed of a pumping piston and a motion conversion groove. The pumping piston is inserted from the rear opening of the launching tube. The motion conversion groove is slidably disposed within the spraying structure housing along its axial direction and extends radially along the spraying structure housing. The reciprocating pumping mechanism includes a power turntable installed within the spraying structure housing and positioned opposite the motion conversion groove. A drive rod is located on the side of the power turntable near the motion conversion groove, offset from the center, and is inserted into the motion conversion groove. When the power turntable of the reciprocating pumping mechanism rotates, the drive rod rotates along with the power turntable, and the rotation of the drive rod is converted into the motion conversion groove sliding along the axial direction of the spraying structure housing, thereby realizing the action of the pumping piston pumping water backward and pushing water forward (spraying it out from the front opening of the launching tube) within the launching tube.
[0006] In a preferred embodiment, the reciprocating pushing mechanism further includes a motor and a gear set. The motor and gear set are respectively installed inside the spray structure housing. The gear set includes an output gear, which is coaxially fixed with the power turntable. The motor drives the power turntable to rotate through the gear set.
[0007] In a more preferred embodiment, the gear set further includes multiple sequentially driven transmission gears, one of which is mounted on the output shaft of the motor.
[0008] A preferred embodiment includes an upwardly protruding reinforcing protective cover on the side of the motion conversion slot away from the power turntable. The reinforcing protective cover protects the drive rod located within it and strengthens the motion conversion slot, reducing deformation and thus extending its service life.
[0009] A better embodiment is that the side wall of the push-pull piston is provided with reinforcing ribs, which are connected to the reinforced protective cover. The reinforcing ribs can enhance the strength of the push-pull piston, making it less prone to deformation, and the connection between the reinforcing ribs and the reinforced protective cover can further enhance the strength of the push-pull piston and the motion conversion groove.
[0010] In a preferred embodiment, the motion conversion groove has guide sliders on both sides, and the spray structure housing has two guide grooves. The guide sliders correspond one-to-one with the guide grooves, and each guide slider is inserted into its corresponding guide groove.
[0011] The beneficial effect of this utility model compared with the prior art is that, due to the improvement of the structure of the power conversion part, the rotation of the drive rod of the motion conversion groove and the drive rod of the power turntable are used to realize the conversion of the rotation of the drive rod into the linear reciprocating motion of the motion conversion groove. There is only rolling friction between the two, so the motion conversion groove and the drive rod of the power turntable are not easily damaged, effectively extending the service life of the parts (motion conversion groove and power turntable).

[0018] like Figure 1-6As shown, a reasonably structured toy water gun spraying structure in one embodiment of this application includes a spraying structure housing 1, a launching tube 2, a pusher 3, and a reciprocating pusher mechanism 4. The launching tube 2 and the reciprocating pusher mechanism 4 are respectively installed inside the spraying structure housing 1. The pusher 3 is formed by connecting a pusher piston 301 and a motion conversion groove 302. The pusher piston 301 is inserted from the rear end opening of the launching tube 2. The motion conversion groove 302 is slidably disposed inside the spraying structure housing 1 along the axial direction and extends radially along the spraying structure housing 1. The reciprocating pusher mechanism 4 includes a power turntable 401, which is installed inside the spraying structure housing 1 and is disposed opposite to the motion conversion groove 302. A drive rod 4011 is provided on the side of the power turntable 401 near the motion conversion groove 302, off-center. The drive rod 4011 is inserted into the motion conversion groove 302. When the power turntable 401 of the reciprocating pumping mechanism 4 rotates, the drive rod 4011 rotates with the power turntable 401, and the rotation of the drive rod 4011 is converted into the motion conversion groove 302 sliding along the axial direction of the spray structure housing 1, thereby realizing the action of the pumping piston 301 pumping water backward and pushing water forward (spraying it out from the front opening of the launch tube 2) inside the launch tube 2.
[0019] like Figure 3-5 As shown in one embodiment of this application, the reciprocating pushing mechanism 4 further includes a motor 402 and a gear set 403. The motor 402 and the gear set 403 are respectively installed in the spray structure housing 1. The gear set 403 includes an output gear 4031, which is coaxially fixed with the power turntable 401. The motor 402 drives the power turntable 401 to rotate through the gear set 403.
[0020] like Figure 3-5 As shown in one embodiment of this application, the gear set 403 further includes a plurality of sequentially driven transmission gears 4032, one of which is mounted on the output shaft of the motor 402. The power of the motor is transmitted sequentially to the output gear 4031 through these transmission gears 4032, thereby driving the power turntable 401 to rotate.
[0021] like Figure 3-6 As shown in one embodiment of this application, a reinforcing protective cover 3021 protruding upwards is provided on the side of the motion conversion groove 302 away from the power turntable 401. The function of the reinforcing protective cover 3021 is to protect the drive rod 4011 located inside the reinforcing protective cover 3021 and to reinforce the motion conversion groove 302, reducing the deformation of the motion conversion groove 302, thereby extending the service life of the motion conversion groove 302.
[0022] like Figure 4 , 5As shown in one embodiment of this application, the side wall of the push-pull piston 301 is also provided with reinforcing ribs 3011, which are connected to the reinforcing protective cover 3021. The reinforcing ribs 3011 can enhance the strength of the push-pull piston 301, making it less prone to deformation, and the connection between the reinforcing ribs 3011 and the reinforcing protective cover 3021 can further enhance the strength of the push-pull piston 301 and the motion conversion groove 302.
[0023] like Figure 1 , 2 As shown in one embodiment of this application, the motion conversion groove 302 has guide sliders 3022 on both sides, and the spray structure housing 1 has two guide grooves 101. The guide sliders 3022 correspond one-to-one with the guide grooves 101, and each guide slider 3022 is inserted into the corresponding guide groove 101.
[0024] like Figure 3-6 As shown in one embodiment of this application, the push piston 301 and the motion conversion groove 302 are integrally formed.
[0025] like Figure 1 , 2 As shown in one embodiment of this application, the spray structure housing 1 is composed of two housing assemblies 102.
[0026] like Figure 3 As shown in one embodiment of this application, a nozzle 201 is installed at the front end outlet of the launch tube 2.
[0027] like Figure 1-3 As shown in one embodiment of this application, a water inlet pipe 202 is installed at the front of the launching tube 2.
[0028] The following is combined with Figure 1-6 Let me introduce the work process:
[0029] The motor 402 operates, driving the power turntable 401 to rotate via the gear set 403. The drive rod 4011 of the power turntable 401 rotates with the power turntable 401, converting its own rotation into a linear reciprocating motion of the motion conversion groove 302 along the axial direction of the spray structure housing 1. In this way, the pumping piston 301 continuously and alternately performs the actions of pumping water backward and pushing water forward (spraying it out from the front opening of the launch tube 2) inside the launch tube 2.
[0030] Since the power conversion part (drive rod 4011 of power turntable 401 and motion conversion groove 302) does not have a tooth and rack meshing structure, it is not easily damaged, which effectively extends the service life of power turntable 401 and push part 3, and also extends the service life of toy water guns made using the toy water gun spraying structure of this embodiment.
[0031] Furthermore, it should be noted that the names of the various parts of the specific embodiments described in this specification may differ. All equivalent or simple variations made to the structure, features, and principles described in this utility model patent concept are included within the protection scope of this utility model patent. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not deviate from the structure of this utility model or exceed the scope defined in these claims, they should all fall within the protection scope of this utility model.
