The funnel body is divided into a head and a neck, and the angle A of the cross section of the neck is 30°≤A≤90°. A plurality of through holes from top to bottom are provided in the wall of the funnel body. However, in actual use, when refueling, the device has no obstruction for the oil, so that the oil directly enters the fuel tank, and then the oil impacts each other, resulting in a large number of bubbles, thereby affecting the refueler's observation of the oil amount.

And the connecting plate 410, the outer wall of the connecting plate 410 is slidably connected to the inner wall of the connecting box 406, a first spring 405 is connected to one side of the connecting plate 410, and the other end of the first spring 405 is connected to one side of the inner wall of the connecting box 406, both sides of the second buffer plate 402 are connected to rotating blocks 413, and a plurality of connecting grooves are provided on the inner wall of the connecting pipe 3, and the connecting grooves are rotatably connected to the corresponding outer walls of the rotating blocks 413, a supporting groove is provided on one side of the connecting plate 410, and the inner wall of the supporting groove is slidably connected to a support rod 407, the other end of the support rod 407 is connected to one side of the inner wall of the connecting box 406, and the first spring 405 is sleeved on the outer wall of the support rod 407, sliding grooves 408 are provided on both sides of the inner wall of the connecting box 406, and a sliding block 409 is slidably connected in the sliding groove 408, and one side of the sliding block 409 is connected to one side of the connecting plate 410.

[0027] In a specific embodiment, a support rod 407 is provided to support the first spring 405 so as to avoid bending and shaking of the first spring 405 during compression, thereby affecting the rebound effect of the first spring 405. A sliding block 409 is provided to slide in the sliding groove 408, thereby avoiding offset when the connecting plate 410 moves, thereby causing jamming and affecting contraction.

[0028] The inner wall of the funnel body 1 is provided with two fixing devices 5, which include a built-in groove 501. The built-in groove 501 is opened on one side of the inner wall of the funnel body 1. The inner wall of the built-in groove 501 is slidably connected with a pin rod 503, and one end of the pin rod 503 is connected to a second spring 505. The other end of the second spring 505 is connected to one side of the inner wall of the built-in groove 501, and the inner wall of the built-in groove 501 is provided with two limiting grooves 502, and a limiting rod 504 is slidably connected in the limiting groove 502. One side of the limiting rod 504 is connected to the outer wall of the pin rod 503, and the end of the pin rod 503 away from the second spring 505 is spherical. The inner wall of the funnel body 1 is fitted with a filter plate 2, and the outer wall of the filter plate 2 is provided with two pin holes, and the two pin holes are plugged with one end of the corresponding pin rod 503.

[0029] In a specific embodiment, one end of the pin rod 503 is set to be spherical, so that when squeezing the pin rod 503, the spherical curvature makes squeezing convenient, and it is also more convenient to replace and remove, and no additional mechanism is required for operation. By setting the limit rod 504 to slide in the limit groove 502, the pin rod 503 is prevented from sliding out of the built-in groove 501 excessively due to the elastic force of the second spring 505, resulting in the pin rod 503 being unable to contact the spherical surface when being squeezed, thereby affecting the fixing operation.

[0030] Working principle: When in use, press the filter plate 2 downwards and squeeze the pin 503 at the bottom of the filter plate 2, so that the pin 503 moves inwards and squeezes the second spring 505. When the pin hole on one side of the filter plate 2 is aligned with the pin 503, the elastic force of the second spring 505 drives the pin 503 to be inserted into the pin hole, thereby fixing the filter plate 2. When it needs to be replaced, pry the filter plate 2 upwards to move the filter plate 2 to squeeze the pin 503, so that the pin 503 is disengaged from the pin hole, thereby taking out the old filter plate 2 for replacement, thereby making the device more convenient to use and operate, and then the oil product When the oil flows into the connecting pipe 3 after the funnel, it contacts the first buffer plate 401 and the second buffer plate 402, so that the side of the first buffer plate 401 and the second buffer plate 402 that are away from each other moves downward, and then drives the hinge block 411 to move through the hinge seat 412, so that the two hinge blocks 411 respectively drive the connecting box 406 and the connecting plate 410 to move, and the connecting plate 410 moves in the connecting box 406, thereby squeezing the first spring 405, causing the first spring 405 to contract and absorb the impact force, thereby reducing the flow speed of the oil and avoiding a large number of bubbles caused by the impact.
