Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 to 3, there are shown schematic views of a mechanism for launching high-pressure water according to an embodiment of the present invention, which may be applied to a toy water gun or the like for spraying water. The mechanism for launching high pressure water of this embodiment includes a trigger assembly, a transmission assembly, and a spray assembly for attachment to the water outlet end of the high pressure water circuit 50.

The transmission assembly is connected with the trigger assembly, the transmission assembly can move by pulling the trigger assembly (enabling the trigger assembly to move from the stroke starting point to the stroke end point), then the transmission assembly drives the spraying assembly to spray out the liquid in the high-pressure water channel, and the transmission assembly releases the spraying assembly when the trigger assembly reaches a preset position (namely a certain position between the stroke starting point and the stroke end point) in the stroke, so that the spraying assembly stops spraying the liquid.

Thus, when the trigger assembly is pulled, the spraying assembly sprays liquid from the stroke starting point to the preset position, and when the trigger assembly is pulled from the preset position to the stroke end point, the spraying assembly stops spraying the liquid, namely the trigger assembly is pulled once, and the mechanism for emitting high-pressure water sprays the liquid once. When the mechanism for launching high-pressure water is applied to the toy water gun, the effect similar to that of launching water bullets can be realized, and the playability of the toy water gun is greatly improved. Also, since the liquid ejection time is short, the water pressure in the high-pressure water path 50 can be well maintained, thereby enhancing the range of liquid ejection.

In one embodiment of the present invention, the spray assembly includes a shooting pot 21, a shooting pipe 22, a first elastic member 23 and a sealing member 24, wherein the shooting pot 21 is fixed at a water outlet end of the high-pressure waterway 50 and communicated with the high-pressure waterway 50, and one end of the shooting pot 21 far away from the high-pressure waterway 50 is provided with a first mounting hole; the seal 24 is installed in the shooting pot 21.

The launch tube 22 includes an inlet 2211, a jet port, and a fluid passage for communicating the inlet 2211 with the jet port. The discharging tube 22 is installed at the first installation hole of the discharging cylinder 21 in such a manner that the liquid inlet 2211 is located in the discharging cylinder 21 and the discharge port is exposed out of the discharging cylinder 21, and the liquid inlet 2211 is blocked by the sealing member 24 under the elastic force of the first elastic member 23 of the discharging tube 22. For example, in FIG. 2, first resilient member 23 urges launch tube 22 to the left so that inlet 2211 is surrounded by seal 24, preventing liquid from high pressure waterway 50 from entering launch tube 22 through inlet 2211.

The transmission assembly is connected to the portion of the launching tube 22 outside the launching cylinder 21, and the launching tube 22 is driven by the transmission assembly to move against the elastic force of the first elastic member 23 (for example, as shown in fig. 3, the transmission assembly pushes the launching tube 22 to move to the right), so that the liquid inlet 2211 is separated from the sealing member 24, and thus the liquid from the high-pressure water path 50 can enter the liquid inlet 2211, and the liquid entering the high-pressure water path of the liquid flow channel through the liquid inlet 2211 is ejected by the ejection port. That is, the driving assembly drives the launch tube 22 to remove the liquid inlet 2211 on the launch tube 22 from the seal 24, thereby achieving liquid injection. Accordingly, when the transmission assembly is reset (i.e., no further force is applied to the barrel 22, such as when the trigger assembly reaches a predetermined position of travel), the first resilient member 23 urges the barrel 22 to the left, and the inlet port 2211 is again blocked by the seal 24, such that liquid ceases to be ejected from the ejection port of the barrel 22.

In one embodiment of the present invention, the transmission assembly includes a launching rod 31, a sliding sleeve 32 and a guide rod 33, wherein the guide rod 33 is assembled to the launching cylinder 21, the guide rod 33 is parallel to the launching tube 22, one end of the launching rod 31 is fixedly installed by a first pivot 34, and the sliding sleeve 32 is assembled to the launching rod 31 by a pin 35 and is connected with the part of the launching tube 22 exposed out of the launching cylinder 21. When the launching rod 31 rotates around the first pivot 34, the sliding sleeve 32 moves along the guiding direction of the guiding rod 33 by the pin 35, and drives the launching tube 22 to move along the axial direction of the launching cylinder 21. Specifically, the sliding sleeve 32 may have a guide hole therein, through which a guide rod 33 mounted to the shooting cylinder 21 passes and guides the moving direction of the sliding sleeve 32.

The trigger assembly further comprises a movable push block 36, a fixed stop 38 and a second elastic member 37, wherein the movable push block 36 is assembled to the trigger assembly through a second pivot 39, the second elastic member 37 is located between the movable push block 36 and the trigger assembly, and the movable push block 36 abuts against the firing rod 31 (i.e. the end of the firing rod 31 away from the first pivot 34) under the elastic force of the second elastic member 37 and pushes the firing rod 31 to rotate around the first pivot 34 (e.g. counterclockwise in fig. 2 and 3) under the driving of the trigger assembly, so that the firing tube 22 moves rightwards, and the liquid inlet 2211 is disengaged from the sealing member 24, thereby realizing the liquid injection.

The fixed stopper 38 is located on the travel track of the movable push block 36. Referring to fig. 4, the movable push block 36 includes a first inclined surface 3611, the first inclined surface 3611 may be located at an end of the movable push block 36 away from the second pivot 39, and when the trigger assembly moves from the start of the stroke to the end of the stroke and reaches the predetermined position, the fixed stopper 38 contacts the first inclined surface 3611 of the movable push block 36 and pushes the movable push block 36 to rotate around the second pivot 39 (e.g. clockwise in fig. 2 and 3) against the elastic force of the second elastic member 37 via the first inclined surface 3611, so that the movable push block 36 releases the firing rod 31, and at the same time, the first elastic member 23 pushes the firing tube 22 to reset (e.g. leftward in fig. 2 and 3), and the sealing member 24 blocks the liquid inlet 2211 again, and the liquid stops being ejected. In particular, the fixed stopper 38 may have a chamfer thereon, so that the movable push block 36 is pressed down to release the striking rod 31 by the cooperation of the chamfer with the first inclined surface 3611. Specifically, the first inclined surface 3611 may be located on the side protrusion 361 protruding from the side surface of the movable push block 36, and the first inclined surface 3611 faces away from the second pivot 39.

The trigger assembly may specifically include a pull handle 11, a link 12, and a third elastic member 13, wherein the link 12 is elongated and extends below the transmission assembly, the pull handle 11 is connected to the link 12 and drives the link 12 to move in the axial direction of the shooting cylinder 21, and the third elastic member 13 is connected to the link 12 and applies a force to the link 12 to return the link 12 to the stroke starting point. Specifically, as shown in fig. 1-3, the connecting rod 12 is driven to move towards the stroke end by moving the buckle handle 11 to the right, and the third elastic element 13 drives the connecting rod 12 to reset, i.e. return to the stroke start point, after the buckle handle 11 is released.

The movable push block 36 is mounted on the connecting rod 12 through a second pivot 39, specifically, the connecting rod 12 may have a mounting protrusion thereon, and the second pivot 39 is located on the mounting protrusion; the second elastic member 37 is located between the connecting rod 12 and the movable pushing block 36, and during the operation of the trigger assembly (i.e. the connecting rod 12) from the starting point of the stroke to the preset position, the end of the movable pushing block 36 away from the second pivot 39 is away from the connecting rod 12 by the elastic force of the second elastic member 37 and pushes the firing rod 31 to rotate around the first pivot 34; when the trigger assembly reaches the preset position, the first inclined surface of the movable push block 36 pushes the movable push block 36 against the elastic force of the second elastic member 37 by the fixed stopper 38, moves toward the link 12 (e.g., rotates clockwise about the second pivot 39 in fig. 2 and 3) and releases the firing rod 31.

As shown in fig. 4, the movable pushing block 36 includes a protrusion 362 protruding toward the transmission assembly, the protrusion 362 may be located at an end of the movable pushing block 36 away from the second pivot 39, and the movable pushing block 36 pushes the firing rod 31 to rotate around the first pivot 34 through the protrusion 362. The side of the projection 362 facing the second pivot 39 is provided with a second inclined surface 3621, when the link 12 runs from the end of the stroke to the beginning of the stroke under the action of the third elastic member 13, the launching rod 31 pushes the movable push block 36 to rotate clockwise around the second pivot 39 by overcoming the elastic force of the second elastic member 37 through the second inclined surface 3621, so that the projection 362 goes around the end of the launching rod 31 far away from the first pivot 34 to reach the beginning position, that is, after the projection 362 goes around the end of the launching rod 31, the projection rotates counterclockwise around the second pivot 39 under the action of the elastic force of the second elastic member 37. In particular, the end of the firing rod 31 distal from the first pivot 34 may be chamfered to facilitate engagement with a second ramp on the tab 362 to depress the tab 362 back.

In one embodiment of the present invention, an inner bracket 25 may be disposed inside the shooting cylinder 21, the inner bracket 25 is adapted to the inner wall of the shooting cylinder 21 and is sleeved on the inner wall of the shooting cylinder 21, and the inner bracket 25 has a second mounting hole. The second mounting hole and the first mounting hole on the launching cylinder 21 are both arranged along the axial direction of the launching cylinder 21, and the sealing piece 24 is fixed at the end part of the launching cylinder 21 through the inner support 25 in a pressing mode. Accordingly, the launching tube 22 includes a mounting portion 223, a connecting portion 222 and a tubular portion 221, which are connected in sequence and coaxial, the liquid inlet 2211 and the injection port are both located in the tubular portion 221 (the liquid flow channel may also be located in the tubular portion 221), the injection port is located at the free end of the tubular portion 221 and is arranged along the axial direction of the tubular portion 221, and the liquid inlet 2211 is adjacent to the connecting portion 222 and is arranged along the radial direction of the launching cylinder 21.

The diameter of the connecting portion 222 is larger than the diameters of the mounting portion 223 and the tubular portion 221, and when the launching tube 22 is mounted to the launching cylinder 21, the mounting portion 223 is inserted into the second mounting hole, the first elastic member 23 is sleeved on the mounting portion 223 (at this time, the first elastic member 23 may be a spring), the tubular portion 221 is inserted into the first mounting hole, and the sealing member 24 is disposed around the tubular portion 221, that is, the front end of the launching tube 22 is supported by the first mounting hole, and the tail end of the launching tube 22 is supported by the second mounting hole, so that when the launching tube 22 moves to a certain position along the axial direction of the launching cylinder 21, the sealing member 24 can block the liquid inlet 2211 on the tubular portion 221.

Specifically, as shown in fig. 2, the sealing member 24 may close the liquid inlet 2211 on the tubular portion 221 by: the liquid inlet 2211 on the tubular part 221 is blocked at the left side by the sealing member 24 together with the connecting part 222 of the launching tube 22, so that water in the launching cylinder 21 cannot enter the liquid inlet 2211. Also, in order to facilitate the engagement with the sealing member 24, the connecting portion 222 of the launch tube 22 may have a tapered surface on the side facing the sealing member 24, thereby improving the sealing effect.

Furthermore, the sealing member 24 may also close the liquid inlet 2211 on the tubular portion 221 by: inlet 2211 on tubular portion 221 moves to the plane of seal 24 and inlet 2211 is directly covered by seal 24.
