Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an intake shunorkel for intake of air for engine combustion from above the vehicle body in a truck or the like.

(Prior Art) An example of a conventional intake snorkel is shown in FIGS. 4 and 5, where 01 is a duct that is installed on the rear side of the cabin and extends upward, and 02 is a duct 0.
It is a cap connected to the top of 1.

Air is taken in through the intake port located on the underside of the cap 02, reverses inside the cap 02, enters the duct 01, descends through this, passes through the air duct, air cleaner, intake manifold, etc., and enters the combustion chamber of the engine. enter.

(Problems to be solved by the invention) In the above-mentioned conventional intake snorkel, rainwater that flows down the surface of the cap 02 during rainy weather is caught up in the air taken in from the intake port and is sucked into the engine together with it. I was afraid.

Therefore, as shown in FIG. 6, the rain gutter 03 is formed by bending the lower end of the cap 02.
It has been proposed to form the drain port 05 by cutting out a part of the rising piece 04, but this requires manufacturing the cap 02 separately from the duct 01 and then connecting the two. There was a problem in that manufacturing cost and time was required. Further, as shown in FIG. 7, a rain gutter 03 is formed by attaching a drip rail 06 to the outer periphery of the lower end of the cap 02 with rivets 07, and by cutting out a part of the rising piece 06a of the drip rail 06. A device in which a drain port 05 is formed has been proposed, but this has the problem of not only increasing the number of parts but also increasing costs because it takes time and effort to attach the drip rail 06.

(Means for solving the problem) The present invention was proposed to solve the above problem, and its gist is that the duct is installed above the vehicle body and In the intake shunorkel formed by integrally molding a cap with an intake port opening downward from a resin, at least one
a recess extending upward and downward, and a recess extending downward continuously from the lower end of the recess formed on the outer surface of the duct; By fitting the drip rail, a gutter is formed that surrounds the entire circumference of the cap, and at the same time, a drain port communicating with the gutter is formed by the inner peripheral surface of the drip rail and the recess of the cap. The intake snorkel is characterized by this.

(Function) Since the present invention has the above-mentioned configuration, by fitting the drip rail to the outer periphery of the lower part of the cap, a gutter surrounding the cap is formed and at the same time a drain port is formed. .

(Embodiment) An embodiment of the present invention is shown in FIGS. 1 to 3.

The duct 1 and the cap 2 are manufactured by integrally molding resin. Recesses 3 and 4 formed on both sides of the duct 1 and the cap 2 are continuous with each other. A protrusion 6 is protruded from the lower part of the cap 2 over the entire circumference except for the recess 4. Reference numeral 7 denotes an annular drip rail made of a stretchable elastic material such as rubber, and a groove 7a formed on the inner peripheral surface of the drip rail is connected to the projection 6.
The cap 2 is fitted into the lower part of the cap 2 by fitting into the cap 2. Thus, a gutter 8 that opens upward is formed by the outer peripheral surface of the cap 2, the upper surface 7b of the drip rail 7, and the flange 7c rising on the outer peripheral side thereof, and at the same time, a gutter 8 that opens upward is formed by the inner peripheral surface of the drip rail 7 and the recess 4. A drain port 9 communicating with the gutter 8 is formed.
Reference numeral 10 denotes an intake port formed on the lower surface of the cap 2 and opening downward.

The air sucked in from the intake port 10 is reversed in the cap 2, moves down in the duct 1, passes through an air duct, an air cleaner, etc., and is sucked into the engine where it is combusted. Rainwater flowing down the outer surface of the cap 2 during rainy weather enters the gutter 8, flows through the gutter 8, enters the recess 4 through the drain port 9, and is discharged through the recess 3.

(Effects of the invention) In the invention, by fitting the drip rail to the outer periphery of the lower part of the cap, the gutter and the drain port can be formed all at once.

Since the drip rail is made of an elastic material that can be expanded and contracted, by expanding and contracting the drip rail, it can be easily and quickly attached to and removed from the cap.

Since the drain port communicating with the gutter can be formed by the inner circumferential surface of the drip rail and the recess of the cap, there is no need to cut out a part of the rising piece of the drip rail to form the drain port as in the conventional case.

Since there is no need to cut out the rising piece of the drip rail, there is no risk that the cutout will locally expand and break even if the drip rail is extended, and the cross-sectional shape of the drip rail can be made uniform over the entire circumference. The drip rail can be manufactured at low cost and the securing force to the cap can be made uniform over the entire circumference.

The water that has entered the gutter flows downward from the drain opening through the continuous recesses formed on the outer surfaces of the cap and duct, so that the flowing water is caught up in the wind from the vehicle and flows into the cap's intake port. It will not be sucked in.

Since these recesses can be formed all at once when the cap and duct are integrally molded, they can be formed easily and inexpensively.

Claims (1)

[Scope of utility model registration request] In an intake snorkel formed by integrally molding a resin duct with a duct raised above the vehicle body and a cap disposed above the duct and equipped with an intake port opening downward, there is provided at least one vertically extending duct on the outer surface of the lower part of the cap. A recess is formed in the outer surface of the duct, and a recess that extends downward continuously from the lower end of the recess is formed on the outer surface of the duct, and an annular drip rail made of an elastic material that can be expanded and contracted is fitted to the outer periphery of the lower part of the cap. By doing so, a gutter is formed that surrounds the entire circumference of the cap, and at the same time, a drain port that communicates with the gutter is formed by the inner circumferential surface of the drip rail and the recess of the cap.
