FLOW DIVIDING VALVE STRUCTURE FOR TOY GUN

Abstract

A flow dividing valve structure for a toy gun includes: a propulsion portion; a rotating auxiliary portion extended from one face of the propulsion portion; and a latching portion, configured on one end of the rotating auxiliary portion far away from the propulsion portion, where the rotating auxiliary portion is configured with a plurality of wing portions each twisted toward a direction away from the propulsion portion so as to be allowed to have at least one twisted face. Whereby, high pressure gas will drive the rotating auxiliary portion to rotate through the wing portions when flowing through the rotating auxiliary portion, and further remove the frost generated inside a gas chamber so as to prevent the unsmooth operation of the flow dividing valve.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Referring to FIGS. 1 and 2, a flow dividing valve 1 of the present invention mainly includes: a propulsion portion 11, a concave groove portion 111 for the gathering of gas being configured on one face thereof far away from a rotating auxiliary portion 12 mentioned below; the rotating auxiliary portion 12, extended from another face of the propulsion portion 11, a flow dividing hole 121 allowing gas to be passed through being configured thereon, a plurality of wing portions 122 being further configured on the rotating auxiliary portion 12, where an included angle between each two adjacent wing portions 122 is ranged from 115 to 125 degrees, and each wing portion 12 being twisted in a 90 degrees rotation toward a direction away from the propulsion portion 11, allowing the wing portions 122 to respectively have at least one twisted face 123; and a latching portion 13, configured on one end of the rotating auxiliary portion 12 far away from the propulsion portion 11, and allowing an elastic element to be engaged therewith.

[0015] Referring to FIGS. 1 to 7, the flow dividing valve 1 of the present invention is installed in a gas chamber 21 of a bolt 2, and the flow dividing 121 is adjacent to an airway 22. When high pressure gas 3 is passed through the airway 22 to the flow dividing valve 1, a part of the gas will flow toward the flow dividing hole 121, and another part thereof to one side face of the concave groove portion 111. Specifically, the gas 3 will first e contact with the twisted faces 123 when passed through the flow dividing hole 121 toward the front end of the gas chamber 21, and then press the twisted faces 123 after in contact with the twisted face 123 to cause the wing portions 122 to drive the entire flow dividing valve to rotate since the twisted faces 123 are set to be inclined. In addition, the part of gas 3 flowing forward behind the concave groove portion 111 is bounced back to the concave groove portion 111 after striking a piston 4 so as to allow the gas to be more gathered in the concave groove portion 111 that is formed to gather up gas, which generates a better push force to push the flow dividing valve 1 forward to squeeze the elastic elements. Finally, the entire bolt 2 is reset completely after the gas chamber 21 is allowed to be airtight. It can be seen from the description mentioned above that the above actions can not only push the piston 4 to move only using a small amount of gas, and most importantly, but remove conveniently the frost in the gas chamber 21 generated from the heat absorption of fuel gas upon the high-speed rotation of the flow dividing valve 1, allowing the flow dividing valve 1 to be very smoothly moved without any hindrance during the operation.

[0016] However, the above description is merely a preferred embodiment of the present invention, and therefore the scope of the present invention is not so limited, so that the simple modifications and equivalent structural changes applied in the use of the present description and drawings are to be construed in a similar manner and included within the scope of the present invention and expressly incorporated herein by reference.

[0017] Accordingly, the present invention has the following advantages compared to the prior art: [0018] 1. the flow dividing valve 1 is allowed to be rotated upon action through the wing portions 122 configured on the rotating auxiliary portion 12, thereby removing the frost generated inside the gas chamber 21 effectively. [0019] 2. the gas 3 can be gathered up through the design of the concave groove portion 111, allowing the gas chamber 21 to be sealed more smoothly, and further moving the piston 4 more smoothly, allowing the piston 4 to be reset completely.
