Abstract
The utility model discloses a funnel capable of preventing positive pressure in an oil tank. The funnel comprises a funnel body, wherein the outer wall of the funnel body is provided with an air guide channel extending from a small opening end to a large opening end of the funnel body. The air guide channel can be formed by the gas between a protruded structure arranged on the outer wall and the outer wall. Due to the air guide channel, the inside of the oil tank is communicated with the outside, thereby effectively preventing the positive pressure in the oil tank when oil is poured.
Description
Technical field
The utility model relates to a kind of oily funnel that is used in fuel tank, falling.
Background technology
At present, when in fuel tank, falling oil, often need to use funnel, existing funnel generally comprises a big opening end and an osculum end, and during use, oil gets into from big opening end, flows out from the osculum end.Not enough below existing funnel exists: funnel needs to insert the oil inlet of fuel tank in use, after funnel inserts oil inlet; The outer wall and the oil inlet of funnel are fitted fully, make fuel tank internal form an osed top chamber, along with oil constantly gets in the fuel tank; Gas in the fuel tank is made that by constantly compression the gaseous tension in the fuel tank constantly raises, when the gaseous tension in the fuel tank during greater than the gaseous tension of external environment; Just form malleation in the fuel tank; At this moment oily in fuel tank again, the resistance that fluid receives is bigger, is difficult to get in the fuel tank.
The utility model content
The technical matters that the utility model solves provides a kind of funnel oily in fuel tank that is used for that prevents to form in the fuel tank malleation.
The utility model solves the technical scheme that its technical matters adopted: funnel, comprise funnel body, and the outer wall of said funnel body is provided with the air guide channel that is extended to the big opening end of funnel body by the osculum end of funnel body.
Further be: the outer wall upper edge funnel body of said funnel body circumferentially be provided with at least one by the outer male structure that the osculum end of funnel body extends to the big opening end of funnel body, the gap between the outer wall of said outer male structure and funnel body forms said air guide channel.
Further be: comprise at least two said outer male structure, said outer male structure circumferentially being uniformly distributed with along funnel body.
Further be: said outer male structure is extended to the end face of the big opening end of funnel body by the end face of the osculum end of funnel body.
Further be: said outer male structure is the gusset of evagination.
The beneficial effect of the utility model is: through air guide channel is set, in use, can guarantee the exterior gas communication of fuel tank internal and fuel tank, can prevent effectively that like this malleation from appearring in fuel tank internal.
Description of drawings
Fig. 1 is the scheme drawing of the funnel of the utility model.
Be labeled as among the figure: 1-air guide channel, 2-outer wall, the outer male structure of 3-, 4-end face, 5-end face, 6-funnel body, 7-osculum end, 8-big opening end.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further specified.
As shown in Figure 1, the funnel of the utility model comprises funnel body 6, and the outer wall 2 of said funnel body 6 is provided with the air guide channel 1 that is extended to the big opening end 8 of funnel body by the osculum end 7 of funnel body.
During use; Funnel body 6 is connected to the oil inlet place of fuel tank, makes the part of air guide channel 1 be positioned at fuel tank internal, another part is positioned at the fuel tank outside; So just can fall in the oily process; The air pressure that remains fuel tank internal is identical with the exterior air pressure of fuel tank, and then can prevent effectively that fuel tank internal from forming malleation, helps in fuel tank, falling smoothly oily.
The embodiment of above-mentioned air guide channel 1 has multiple, and the groove of indent for example can be set on the outer wall 2 of funnel body 6, and groove extends the just above-mentioned air guide channel 1 of this groove by the osculum end 7 of funnel body 6 to the big opening end 8 of funnel body; Also can on the outer wall 2 of funnel body 6, loop configuration be set, a plurality of through holes are set on the loop configuration, this through hole one end is towards the osculum end 7 of funnel body, and the other end is towards the big opening end 8 of funnel body, the just above-mentioned air guide channel 1 of this through hole.For the ease of processing and use; The preferred implementation of above-mentioned air guide channel 1 is: as shown in Figure 1; The outer wall 2 upper edge funnel bodies 6 of said funnel body 6 circumferentially be provided with at least one by the outer male structure 3 that the osculum end 7 of funnel body extends to the big opening end 8 of funnel body, the gap between the outer wall 2 of said outer male structure 3 and funnel body 6 forms said air guide channel 1.During use, funnel body 6 is connected to the oil inlet of fuel tank, outer male structure 3 is contacted with oil inlet; Owing to be provided with outer male structure 3; Make the outer wall 2 of funnel body 6 can't be fully and oil inlet fit, can have the gap between the outer wall of evagination mechanism 3 and funnel body 6, this gap can form above-mentioned air guide channel 1; And then the air pressure of fuel tank internal and the exterior air pressure of fuel tank are consistent, prevent that effectively malleation from appearring in fuel tank internal.Above-mentioned said outer male structure 3 can be the block structure of evagination, and the list structure of evagination etc. are preferably the gusset of evagination, are convenient to processing like this, and elegant in appearance.
On the basis of the above, for the steady clamping of the oil inlet that helps funnel and fuel tank, when falling oil, the shaking degree of funnel body 6 is less, and above-mentioned funnel body 6 comprises at least two said outer male structure 3, said outer male structure 3 circumferentially being uniformly distributed with along funnel body 6.Because outer male structure 3 is uniformly distributed with, make therefore when falling oil, to help the stressed even of funnel body 6 keeping stablizing.
Better for the commonality of the funnel that makes the utility model, said outer male structure 3 is extended to the end face 4 of the big opening end 8 of funnel body by the end face 5 of the osculum end 7 of funnel body.Adopt said structure, during use, as long as funnel body 6 can with the oil inlet clamping of fuel tank, then outer male structure 3 just can contact with the oil inlet of fuel tank, and then can prevent effectively that malleation from appearring in fuel tank internal.
