Refer to Fig. 1 to Fig. 3, a kind of new float chamber, including float chamber body 2, float 1 and float chamber cavity volume 3；Float 1 It is placed in float chamber cavity volume 3, the inwall of float chamber body 2 is provided with baffle plate 4, and baffle plate 4 is floating towards direction from the inwall of float chamber body 2 The protrusion of seed cell's cavity volume 3 is set, and baffle plate 4 is the first side (not shown) close to the side of the inwall of float chamber body 2, and baffle plate 4 is away from float The side of the inwall of chamber body 2 is the second side (not shown)；Baffle plate 4 is located at below the pasta F height in float chamber cavity volume 3；Baffle plate 4 wraps The first baffle 41 and second baffle 42 along the axial direction dislocation arrangement of float chamber body 2 are included, multiple rings of first baffle 41 are located at On the inwall of float chamber body 2, multiple rings of second baffle 42 are located on the inwall of float chamber body 2.

It is fuel oil depth h to define distances of the pasta F apart from the bottom of float chamber body 2, and first baffle 41 is apart from pasta F's Distance is first baffle depth L1, and second baffle 42 is second baffle depth L2,1/6*h≤L1≤L2 apart from pasta F distance ≤1/2*h；Distance apart from pasta F is bigger, and fluctuation is just smaller caused by shock energy, i.e. the fuel impingement of the bottom of float chamber body 2 The shock that can be far smaller than between pasta F fuel oil, therefore, is disposed close to pasta F by baffle plate 4, can more play reduction The effect of shock.In the present embodiment, first baffle 41 and second baffle 42 be positioned close to pasta F side, i.e. 1/5*h≤ L1≤L2≤1/3*h。

Fig. 2 and Fig. 3 is referred to, several first baffles 41 form a discontinuous ring-type in the inwall of float chamber body 2, several Second baffle 42 forms a discontinuous ring-type in the inwall of float chamber body 2, and first baffle 41 is dislocatedly distributed with second baffle 42； First baffle 41 and second baffle 42 can be sustained height, can also be highly inconsistent.In the present embodiment, L1 ＜ L2, to The fuel oil of the upper lower surface 47 for hitting first baffle 41, after the energy expenditure of lower surface 47 of first baffle 41 part is hit, Part fuel oil changes the upper surface 46 that direction hits second baffle 42, this part fuel oil impingement baffles twice in succession in a short time 4, the energy that energy expenditure will be far longer than an impingement baffles 4 and consume；The combustion of the upper surface 46 of slamming down second baffle 42 Oil, after the energy expenditure of upper surface 46 of second baffle 42 part is hit, part fuel oil changes direction and hits first baffle 41 Lower surface 47, the energy of this part fuel consumption will also be greatly improved.

Thickness of the baffle plate 4 from the first side to the second side is gradually reduced, and baffle plate 4 is in the first side connection float chamber body 2 Wall, when baffle plate 4 is impacted up and down by fuel oil, the impulsive force that the first side is subject to will be greater than the second side, then be rushed closer to the first side It is stronger to hit power, from the second side to the first side direction, the thickness of baffle plate 4 gradually increases, and avoids the damage of baffle plate 4.

Referring to Fig. 4, the upper surface 46 of baffle plate 4 is provided with least one splitter box 45, splitter box 45 with lower surface 47 Along the second lateral first side extension, i.e., along the length direction that the second lateral first side direction is splitter box 45；Wherein, preferably , the cross section of splitter box 45 is circular arc, and the cross section of splitter box 45 is circular arc by the impulsive force flexible buffer of fuel oil, when Fuel oil starts because of the vibrations of carburetor up and down when hitting, fuel oil by impingement baffles 4, fuel oil no matter from which orientation hit into The splitter box 45 of baffle plate 4, fuel oil all will move buffering along the deep-slotted chip breaker surface current of splitter box 45, so as to fuel impingement baffle plate 4 Impulsive force plays buffering；Both the mutual shock between levels fuel oil had been obstructed, has gone back flexible buffer upper strata fuel oil to upper surface 46 impulsive force and lower floor's fuel oil is to the impulsive force of lower surface 47, the further foamed for reducing fuel oil.

Further, the upper surface 46 of baffle plate 4 and lower surface 47 are provided with some splitter boxs 45 in the present embodiment, gear The splitter box 45 of the upper surface 46 of plate 4 and the splitter box 45 of the lower surface 47 of baffle plate 4 are interspersed, and the setting of splitter box 45 causes The thickness of baffle plate 4 is relatively reduced, and the splitter box 45 of upper surface 46 and the splitter box 45 of lower surface 47 are staggered, avoid baffle plate 4 the depressed area of splitter box 45 thickness it is excessively thin and fractureed under impact in fuel oil.

When the setting of baffle plate 4 make it that carburetor shakes, the mutual Impact energy of fuel oil weakens, so as to reduce fuel oil foam Produce, be fuel particle from balance pipe track overflow so as to effectively suppress fuel oil foam；The design of splitter box 45 on baffle plate 4 is right Fuel impingement plays a part of flexible buffer, reduces impulsive force of the fuel oil to baffle plate 4, so as to reduce the generation of fuel oil foam.

Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model Within the spirit and principle of utility model, any modification, equivalent substitution and improvements done etc., the utility model should be included in Within the scope of protection.
