Definitions

• the present invention relates to an exhaust purification device that reduces and purifies nitrogen oxides (NOx) in exhaust using a liquid reducing agent, and when the liquid reducing agent is replenished to a container that stores the liquid reducing agent. It relates to an infusion hose used.
• NOx nitrogen oxides
• an exhaust purification system that purifies NOx into a harmless component by catalytically reducing NOx in the exhaust and a liquid reducing agent. Proposed.
• This exhaust purification device uses a reducing agent supply device controlled by a control unit, and supplies the required amount of liquid reducing agent according to the engine operating state upstream of the reduction catalyst disposed in the engine exhaust system. This is a mechanism for supplying fuel to the jet.
• the reduction reaction mainly uses ammonia that has a good reaction with NOx
• the liquid reducing agent is mainly an aqueous urea solution that is hydrolyzed by exhaust heat and steam in the exhaust to generate ammonia. Used.
• a liquid reducing agent such as an aqueous urea solution is stored in a dedicated storage container mounted on the vehicle.
• the liquid reducing agent stored in the container mounted on the vehicle decreases as the vehicle travels, so it is necessary to replenish appropriately.
• a new liquid reduction provided in a hand-held tank of a specified capacity (for example, a tank similar to a kerosene plastic can or a cardboard tank lined with a resin bag inside). Transfer the agent by hand to the on-board container.
• the liquid reductant tank containing the liquid reductant for replenishment is configured such that a flexible injection hose can be attached to the spout, and a container for transferring the liquid reductant The injection hose is inserted into the injection port so that the injection can be performed. After replenishing the liquid reducing agent, remove the injection hose, and the removed injection hose can be used for the liquid reductant tank at the next replenishment and can be turned!

• an object of the present invention is to appropriately and easily store an injection hose removed from a liquid reducing agent tank without incurring additional costs.
• the present invention is inserted into an end portion having a shape attachable to a spout of a liquid reducing agent tank and an inlet provided in a container for transferring the liquid reducing agent from the tank.
• An end portion having a possible shape and a flexible intermediate portion connecting between the two end portions, and at least an outer peripheral surface of one of the two end portions.
• one ridge (or groove) is provided around and at least one groove (or ridge) is provided around the other inner peripheral surface, and the engagement between these ridges and the grooves
• the present invention proposes a liquid reducing agent injection hose characterized in that the intermediate part can be kept annular by connecting the two ends. The invention's effect
• the injection hose according to the present invention can be formed into an annular shape (endless shape) by connecting the two end portions by engaging the ridges and the recesses after being removed from the tank, It is possible to store the hollow middle part in a closed space where at least foreign matter such as dust does not enter.
• the present invention only the ridges or ridges are provided around the two end portions located with the intermediate portion interposed therebetween, so that it is possible to cope with only slight modification of the mold, such as the opening cover. No new parts are required, and no additional cost is required.
• the hose for injection has been used up and the tank power has been removed, the concave and convex strips at the two ends are engaged with each other just as if they were a “snap feed”. Therefore, an injection hose that solves the conventional problems and is optimal for the liquid reducing agent of the exhaust gas purification apparatus is provided.
• FIG. 1 is an external view including a partial cross section showing an injection hose according to an embodiment of the present invention in a straight line state.
• FIG. 2 is an external view showing the injection hose of FIG. 1 in an annular state.
• FIG. 1 A preferred embodiment of the present invention will be described with reference to the drawings.
• the injection hose according to the present embodiment is schematically shown in FIG. 1 as a straight state and as shown in FIG. 2 as an annular shape by engaging two ends.
• the injection hose 1 has an end 2 having a shape that can be attached to a spout (not shown) of a hand-held tank containing a liquid reducing agent, and a storage container for an exhaust purification device that transfers the liquid reducing agent.
• An end portion 3 having a shape that can be inserted into an inlet (not shown) and an intermediate portion 4 having flexibility connecting the end portion 2 and the end portion 3 are configured.
• the intermediate part 4 of this embodiment is a bellows type and can be bent freely. In addition to the bellows type, it is necessary to use a material that does not affect the liquid reducing agent.
• a structure in which the material is formed into a bellows type to increase the thickness and strength is suitable.
• the end portion 2 includes an outer diameter large diameter portion 2a fitted to the inner diameter of the tank outlet, and a funnel portion 2b gradually tapering from the large diameter portion 2a, the funnel portion A recess 2c is provided around the inner peripheral surface of 2b.
• the concave strip 2c is not limited to the position shown in the figure, that is, provided at the boundary position between the end portion 2 and the intermediate portion 4.
• the inner diameter of the recess 2c of the present embodiment is larger than the inner diameter of the intermediate portion 4, and when the two end portions 2, 3 are connected to each other, the end portion 3 becomes the end portion 2 It is designed not to go deeper than the concave 2c.
• the recess 2c can have the same diameter as the intermediate part 4 or a small diameter.
• the large-diameter portion 2a of the end 2 is provided with a locking step 2d on the outer peripheral surface thereof, and when the end 2 is fitted into the tank outlet, the inner peripheral surface of the outlet The step 2d is locked to the step provided in the hose so that the hose 1 does not easily fall off during injection.
• a flange 2e is provided on the outer peripheral surface so as to partition the boundary between the large diameter portion 2a and the funnel portion 2b, and when the large diameter portion 2a is fitted into the tank outlet, the outlet The flange 2e abuts on the edge of the nozzle, and serves as a stopper that prevents the end 2 from entering the back of the spout and a lid that closes the gap.
• the end portion 3 Since the end portion 3 is more rigid than the need to be flexible, it is formed in a cylindrical shape that is thicker than the intermediate portion 4. And on the outer peripheral surface of the tip of this end portion 3, A protrusion 3a that engages with the recess 2c of the end 2 is provided around the periphery.
• the position of the ridge 3a is not limited to this, and may be an intermediate portion of the end 3 or the like.
• the present embodiment shows an example in which the recess 2c is provided around the inner peripheral surface of the end 2 and the protrusion 3a is provided around the outer periphery of the end 3.
• a protruding line may be provided around the inner peripheral surface of the part 2, and a concave line may be provided around the outer peripheral surface of the end part 3.
• two or more ridges and ridges can be provided around, thereby increasing the engagement force between them.
• the diameter of the end 2 may be smaller than the diameter of the end 3, but in this case, a ridge or a groove is provided on the inner peripheral surface of the end 3 having the larger diameter. Then, it is only necessary to provide a recess or protrusion on the outer peripheral surface of the end 2 having the smaller diameter.

• a liquid reducing agent tank When storing it after it has been used and removed from the tank, store it in an annular shape as shown in Fig. 2. That is, by bending the intermediate part 4 and inserting the end part 3 into the end part 2 and engaging the protrusion 3a with the recess 2c in a snap-fit manner, the two ends 2 and 3 are joined together.
