[0049] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0050] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0051] In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, an integral connection, or a detachable connection; it can be the internal connection of two components; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] like Figure 1 , Figure 2 As shown, a toy bubble gun of this embodiment includes a gun body 10 , a gun barrel 20 , a water storage cylinder 50 and a trigger 70 .

[0053] The improvement of this embodiment over the prior art is that, the gun barrel 20 includes a water storage section 21 and a shaped outlet section 22, the water storage section 21 and the shaped outlet section 22 are connected by a connecting portion 24, and the connecting portion 24 is provided with a Fig. 9 The elastic plug 25 shown. The elastic plug 25 separates the water storage section 21 and the formed outlet section 22. The elastic plug 25 is provided with a cutout 26 that passes through the elastic plug 25 and is configured to be sealed at the cutout under normal pressure.

[0054] In this embodiment, the tail end of the water storage section 21 is connected to a pressure release mechanism for releasing compressed gas. The pressure release mechanism is provided with a pressure relief mechanism, and a trigger is connected to the pressure relief mechanism, and the pressure relief mechanism is triggered by pulling the trigger. Its working principle is that in the initial state, the water storage section 21 is full of water. Since the incision 26 of the elastic plug 25 is sealed under normal pressure, water will not flow out from the incision. After the pressure relief mechanism is triggered by the trigger, the high-pressure compressed gas in the pressure release mechanism instantly enters the water storage section 21 through the pressure release port. Under the action of the compressed gas, the water in the water storage section opens the incision 26, and is ejected from the water storage section 21. Since the incision 26 makes the ejected water flow more scattered, the forming outlet section 22 converges the more scattered water flow, pressurizes the water flow and shapes it.

[0055] The toy bubble gun of this embodiment breaks the spraying principle of traditional water guns. It uses compressed gas to spray all the water in the water storage section at one time. The amount of water sprayed at a time is large and forms water droplets, and the spraying distance is far. In addition, the role of the trigger is to trigger the pressure relief mechanism, which requires less force and does not affect the distance and amount of water sprayed. Compared with the traditional triggering trigger, the force, speed, and amplitude will affect the amount and distance of the sprayed water flow. It is more convenient to operate and has a better experience. No matter how the trigger is operated, it can ensure that the sprayed water flow is in the best state.

[0056] The pressure release mechanism of this embodiment is as follows: Figure 2-Figure 7 As shown, it includes an air storage cylinder 30, in which an air storage cavity 31 is arranged.

[0061] In this embodiment, the air plug 34 has a first position in sealing contact with the vent pipe 32. Figure 5 , Figure 6 As shown, the gas plug 34 has a second position in sealing contact with the pressure release port 361, which is as shown in FIG. Figure 3 , Figure 4 As shown. Preferably, a sealing plug 35 is sleeved on the pressure release port 361 to ensure the sealing of the second position.

[0062] In this embodiment, the air plug 34 can move between the first position and the second position. When the air plug 34 is not in the first position, the vent pipe 32 is connected to the air storage chamber 31. Preferably, in this embodiment, a ventilation gap is provided between the outer wall of the air plug 34 and the inner wall of the sliding chamber 331.

Preferably, the elastic mechanism 72 is a compression spring. A mounting groove 73 for mounting the sealing gasket 62 is provided on the trigger.

[0070] In this embodiment, the water storage cylinder 50 is connected to the water replenishment port of the water storage section 21 . The water storage cylinder 50 is located above the gun barrel 20 . The water storage cylinder 50 is provided with a water inlet 52 and a sealing cover 53 .

[0071] In this embodiment, the water storage section 21 is provided with an inclined tube 23 extending upwardly at a position close to the pressure release mechanism, and correspondingly, the water storage cylinder is provided with an inclined tube 51 extending downwardly at a tilted angle, and the inclined tube 23 is inserted into the inclined tube 51, so that the water storage cylinder is connected with the water storage section. As a preferred embodiment, in this embodiment, Figure 2 As shown, a sealing groove 231 is provided on the inclined tube 1 23 , and a sealing ring 232 is installed in the sealing groove 231 for achieving sealing with the inclined tube 2.

[0072] As an improvement of this embodiment, a movable valve core 27 is provided between the water storage cylinder 50 and the water storage section 21, and the movable valve core 27 is installed in the inclined tube 1 23. The movable valve core 27 of this embodiment, such as Figure 8 As shown, it includes a tube 271 adapted to the inner cavity of the inclined tube 1 23, the lower end of the tube 271 is a closed end surface 272, and the upper end is open. The side wall of the tube 271 is provided with a water inlet hole 273 facing the water storage section 21.

[0073] In this embodiment, the movable valve core 27 has two movement limit positions, namely, a first sealing position and a second sealing position, and the movable valve core 27 is movable between the first sealing position and the second sealing position. Figure 3 , Figure 4 As shown, the closed end surface 272 and Fig.12 The inclined annular surface 363 of the connecting pipe 362 is in sealing contact. In the first sealing position, the water storage section 21 is connected to the water storage cylinder 50 through the water inlet hole 273. The water storage cylinder is connected to the water storage section and is separated from the pressure release port by a movable valve core.

[0074] In the second sealing position, as Figure 5 , Figure 6 As shown, the water inlet hole 273 is in sealing contact with the inner wall of the inclined tube 23. In the second sealing position, the water storage section is connected to the pressure release port and is separated from the water storage cylinder by the movable valve core.

[0075] Preferably, in this embodiment, the movable valve core 27 is axially movable with the inclined tube 1 23. In a preferred embodiment, the cross section of the movable valve core 27 is elliptical. Of course, the cross section of the movable valve core can also be other non-circular structures, and of course, it can also be a circular structure with an axial guide structure.

[0076] Preferably, in the present embodiment, a limiting ring platform adapted to the upper end surface of the movable valve core 27 is provided in the inclined tube 51 to limit the upper limit position of the movable valve core.

[0077] Preferably, in this embodiment, a reinforcing rib 274 extending along the axial direction of the movable valve core 27 is provided in the water inlet hole 273 to ensure that the movable valve core 27 has a higher structural strength during the axial movement and prevent the movable valve core from being deformed.

[0078] The working principle of the toy bubble gun of this embodiment is as follows: in the initial pressure-maintaining state, Figure 3 , Figure 4 As shown in FIG. 1 , the movable valve core is in the first sealing position under the action of gravity, and the water in the water storage cylinder flows into the water storage section until the water storage section is filled. In this state, the slider is operated back and forth to achieve inflation through the vent pipe. In this process, Figure 4 As shown in the figure, based on the inflation pressure, the air plug and the pressure release port are in a sealed state, forming high pressure in the air reservoir, the vent pipe and the transition chamber. Figure 7 As shown, by pulling the trigger, the sealing gasket contacts the seal of the vent hole, and the vent pipe is connected to the outside, so that the pressure in the air storage cylinder is greater than the pressure in the vent pipe. Figure 6 As shown, under the action of the pressure difference, the air plug is driven to seal the vent pipe, so that the pressure release port is unsealed. The compressed gas in the air storage cylinder, due to its high pressure, instantly enters the water storage section through the pressure release port. The high-pressure gas first drives the movable valve core to move to the second sealing position, and then sprays the water in the water storage section from the cutout of the elastic plug. Due to the cutout, the sprayed water flow is scattered, and the outlet forming section converges the water flow to spray out a water column.

[0079] In short, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
