    (a) Technical field of the invention
    The present invention relates to a toy gun, and more particularly to a flow-splitting valve structure for a toy gun capable of removing frost in a gas chamber thereof. (b) Description of the Prior Art
    Currently, toy guns are prevalent among adults and children; they fully satisfy the desire of players during shooting games such as a survival game, and which can be considered safe and meet the needs of players. However, toy gun structures have been continuously improved to allow the feel or timing of toy gun fire to be closer to the true texture of a weapon. Among these, taking as an example the flow-splitting valve structure of a gas pistol, the general flow-dividing valve is very simple, mainly comprising a long rod, one end of which is provided with a seat engagement member for securing an elastic member, and another end having a flat surface which allows the impact of the gas to act upon it in such a manner that an air cylinder can be pushed back steadily through the flow-dividing valve to effect a return action of the bolt in its original position.
    However, when the conventional flow-dividing valves are in a state of use, the following problems and defects are to be overcome: although the conventional flow-splitting valve may push an air cylinder to effect a return action. original position of the bolt, the propellant gas will absorb heat during the flow of gas, which causes the formation of frost in the gas chamber. As a result, the flow-dividing valve does not move smoothly and will be prevented from operating once the gas chamber is frosted.
    SUMMARY OF THE INVENTION
    The present invention is provided to overcome the above-mentioned defects.
    The main object of the present invention is to provide a flow splitter valve for a toy gun, allowing a flow splitter valve to rotate due to fin forming portions on a rotating auxiliary portion, thereby effectively eliminating ice formation. generated inside a gas chamber.
    Another object of the present invention is to provide a flow splitter valve for a toy pistol, able to accumulate gas due to the design of a concave groove-shaped portion, allowing the gas chamber to be closed in a more progressive manner and furthermore to move a piston more evenly for its complete return to the starting position.
    To achieve the above-mentioned objects, the present invention provides a flow-splitting valve structure for a toy gun, comprising: a propulsion portion; a rotating auxiliary portion extending from a face of said propulsion portion, a flow-splitting hole being provided thereon, permitting the passage of gas therethrough, the rotating auxiliary portion being arranged with a plurality of fin portions each being twisted in a direction away from said propulsion portion, allowing said plurality of fin portions to each have at least one twisted face; and an engagement portion, provided on one end of said rotatable auxiliary portion remote from said propulsion portion, allowing engagement of an elastic member therewith.
    The high pressure gas thus contacts the twisted faces as it is guided through the flow-splitting hole to cause the entire flow-dividing valve to rotate, thereby removing frost from the gas chamber. and a portion of the gas will be returned to the concave groove portion after a plunger stroke, allowing the flow-dividing valve to be urged in a direction away from the piston by the gas pressure.
    In addition, a bolt can be completely returned to the starting position after the gas chamber has been made airtight, and the piston can be urged to move even if the gas is insufficient. In addition, an eddy current will be provided due to the rotation of the flow divider valve, allowing the pressurized gas to push a ball forward to stabilize the bale velocity.
    According to another aspect of the invention, a portion forming a concave groove adapted to collect gas is provided on a face of said propulsion portion remote from said rotating auxiliary portion.
    According to another aspect of the invention, said flow-dividing valve is installed inside a gas chamber of a moving bolt.
    According to another aspect of the invention, the angle between each of the two parts forming adjacent fins is between 115 and 125 degrees.
    According to another aspect of the invention, each said fin portion is twisted at 90 degrees of rotation toward a direction away from said propulsion portion.

    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
    With reference to FIGS. 1 and 2, it will be apparent that a flow-split valve 1 according to the present invention mainly comprises: a propulsion portion 11; a portion 111 forming a concave groove for gas collection, provided on one side of the remote portion 11 of a rotating auxiliary portion 12 mentioned below; the rotating auxiliary portion 12, extending from another face of the propulsion portion 11; a hole 121 of flow division, allowing the passage of gas through it, is arranged on the latter; a plurality of fin-forming portions 122 further provided on the rotating auxiliary portion 12, the angle between each of the two adjacent fin portions 122 being between 115 and 125 degrees and each fin portion 12 being twisted on a rotation 90 degrees in a direction away from the propulsion portion 11, which allows the portions 122 forming fins to each have at least one twisted face 123; and an engagement portion 13, arranged on one end of the rotating auxiliary portion 12, remote from the propulsion portion 11, and allowing the engagement with it of an elastic member.
    With reference to FIGS. 1 to 7, it appears that the flow-dividing valve 1 according to the present invention is installed in a gas chamber 21 of a moving breech 2 and that the flow division 121 is adjacent to a passage of 22. When high-pressure gas 3 passes through the air passage 22 to the flow-dividing valve 1, some of the gas will flow to the flow split hole 121 and another portion thereof will flow to a side face of the portion 111 forming a concave groove. In particular, the gas 3 will first contact the twisted faces 123 as it passes through the flow-splitting hole 121 towards the front end of the gas chamber 21, and then presses the twisted faces 123 after being in contact with the twisted face 123 to cause the fin-forming portions 122 to drive the entire flow-dividing valve to be rotated since the twisted faces 123 are inclined. In addition, the part of the gas 3 flowing forwards behind the concave groove portion 111 is returned to the concave groove portion 111 after bearing against a piston 4 so as to allow the gas to be further collected in the portion 111 forming a concave groove which is formed to generate a gas buildup, which generates a better thrust force, to urge the flow-dividing valve 1 forward to press the elastic members. Finally, the whole of the bolt 2 is put back in place completely after the gas chamber 21 is made airtight. It can be seen from the foregoing description that the above actions can not only push the piston 4 to move only using a small amount of gas and, more importantly, can properly remove the frost in the chamber. with gas 21 generated by the thermal absorption of the propellant gas during the high speed rotation of the flow-dividing valve 1, allowing the flow-dividing valve 1 to be moved very easily and without any hindrance during operation .
    The foregoing description is that of a preferred embodiment of the present invention and, therefore, the scope of the present invention is not limited thereto, so that simple modifications and equivalent structural changes applied in the use of the subject of the present description and the drawings must be interpreted in a similar manner and included within the scope of the present invention.
    Consequently, the present invention has the following advantages over the prior art: 1. the flow-dividing valve 1 is allowed to rotate during its action due to the fins 122 formed on the rotating auxiliary part 12, thereby effectively removing the frost generated within the gas chamber 21; 2. the gas 3 can be accumulated due to the design of the portion 111 forming the concave groove, allowing the gas chamber 21 to be closed more evenly, and further to move the piston 4 more regularly , allowing the piston 4 to be completely returned to the starting position.
