It has a professional position, and the surface gas circuit extends to the periphery of the tank lock seat and communicates with the outside, and has a vent hole on the ventilation circuit to communicate with the inside of the tank lock seat, so that it can be drawn through the ventilation circuit when refueling The outside air enters the tank lock seat. The ventilation is greatly improved, which makes the fuel flow smoother and rides smoother. However, in the above-mentioned conventional fuel tank lock seat, the connection between the ventilation circuit and the fuel tank lock seat is set to the lack of σ; in addition, most of the fuel tank caps of today's vehicle types are not placed at the rear end of the vehicle, and are inclined upward. At the rainy day, the rainwater will flow in through the gap between the oil lock seat and the ventilation circuit, and even penetrate into the ventilation circuit through the gap between the fuel tank lock and the fuel tank lock cover, and then flow into the fuel tank. In the above case, if the locomotive is refueling, the water that has penetrated into the venting circuit will be quickly fed into the tank lock seat through the intake passage with the central air of the external air. SUMMARY OF THE INVENTION The present invention relates to a multiple circuit of a fuel tank lock external vent pipe, which is improved to solve the lack of external ventilation passage of the above-mentioned conventional fuel tank lock, so as to effectively prevent external rainwater from entering the fuel tank lock with air suction. Insider. 1284606 The utility model comprises a fuel tank lock seat and a waterproof pad, wherein: a ventilation circuit connected to the inner side of the fuel tank lock seat is arranged on the outer side of the oil tank lock seat, and a file is arranged on the ventilation circuit at the junction with the outside, and is ventilated. Opened on the circuit - the air inlet through the external atmosphere, and a vent pipe extending corresponding to the air inlet hole at the bottom of the tank lock seat; the viscous circuit corresponding to the fuel tank lock seat is formed on the waterproof pad surface to cover When it is on the fuel tank lock seat, the convex edge of the waterproof pad is blocked on the side edge of the ventilation circuit, so that the ventilation circuit is self-contained. Therefore, the present invention can effectively block the external water from directly penetrating into the inner portion of the tank lock to achieve an excellent waterproof effect. [Embodiment] As shown in the first and second figures, the present invention includes a fuel tank lock seat (1) and a waterproof pad (2), and is relatively covered with a fuel tank lock cover (3), wherein: the fuel tank lock seat (1) A ventilation circuit (11) is disposed on the outer seat surface, and the path of the ventilation circuit (11) extends from the inside to the outside, and the end point of the extension does not communicate with the outer periphery of the tank lock seat (1), and the ventilation circuit The starting point of (11) is a first air inlet hole (1U) communicating with the inside of the fuel tank lock seat (1), and the first end of the air circulation circuit (11) is provided with a first connection with the outer side of the fuel tank lock seat (1). Two air inlet holes (112), and corresponding to the second air inlet hole (112) at the bottom of the fuel tank lock seat (1), extending a suitable length of the air pipe (12), and protruding from the periphery of the air pipe (12) The 垣 (121) is abutted, and a plurality of perforations (13) are provided on the tank lock seat (1). The waterproof 塾 (2) surface is corresponding to the venting circuit (11) of the fuel tank lock seat (1) and the convex portion 1284606 21 (21) 'and corresponding to the perforation 〇 3 on the tank lock seat (!) and the through hole is opened (22) ). The fuel tank lock cover (3) is provided corresponding to the fuel tank lock seat 〇), and a locking hole (magic) is provided on the corresponding hole (13) of the oil lock seat (1). By the way, in the group setting, as shown in the first and third figures, the waterproof pad (2) is placed on the surface of the fuel tank lock seat (1) to pass through the convex surface of the waterproof pad (2) (21). Block the two side edges of the ventilation circuit (11) so that the ventilation circuit (11) and the tenon (21) form a closed channel; the fuel tank lock cover (3) is opposite to the waterproof pad on the fuel tank lock seat (1). (2) Covering the locking hole of the bolt (4) with respect to the perforation (13) of the tank lock seat and the through hole (22) of the waterproof mat (2), and locking the lock on the tank lock cover (3) ( 31), through the tank lock cover (3) face relative to the tank lock 〇), the bulge (21) on the waterproof mat (2) is completely blocked against the venting circuit of the tank lock 〇丨) On the two sides; in this way, even if the rainwater is not covered by the tank lock (1), it can not penetrate into the second intake hole (2) of the ventilation circuit (8) due to the waterproof (2) barrier, so as to avoid the liquid and the external The air is blown together into the inside of the tank lock seat (1); in addition, the bottom of the tank lock seat (1) is provided with a vent pipe (10), so that the rainwater can be effectively guided by the vent pipe (12) at the end, even if the outside air by When the trachea (12) draw, rain would be difficult to seat will lock into the tank (1) inside. ^, the vent pipe (12) of the fuel tank lock seat (1) is set as a tapered pipe body, or as shown in the fourth figure, the snorkel pipe (12) of the fuel tank lock seat (1) is connected in a step-by-step manner. ^The conduit (5)' makes the ventilation; ^(12) the length of the tube can be extended even more, because the snorkel (12) is provided with abutting 垣(m), so when the catheter (5) is attached thereto, The positioning of the crucible (m) can be prevented from rotating the duct (5) on the vent tube (10). Moreover, the catheter (3) disclosed in the present invention can be provided with a plurality of partitions (9) at the inner circumference of the tube of the conduit (5) 7 Ϊ 284606 as shown in the fifth figure, and the outer partition can be used as the partition (51). The staggered arrangement allows the air to be fed back into the snorkel to effectively prevent rainwater from being directly inhaled with the air. In addition, or as shown in the sixth figure, the duct (6) is arranged in an L shape, so that the direction of the air inlet of the duct (6) is opposite to the direction in which the raindrops fall, and the duct (6) is more like the seventh duct. (6) The inner tube is further interlaced to form a number of partitions (δ1), which also have the same effect of preventing the inhalation of water from the outside air. ,
