Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, technical solution of the present invention is described in detail, to be further understood that the purpose of the present invention, scheme and effect, but is not intended as the restriction of claims protection domain of the present invention.
Consulting the partial sectional view of the first embodiment of the carburetor that Fig. 2 to Fig. 3, Fig. 2 are the present invention, Fig. 3 is the E place enlarged drawing of Fig. 2.As it can be seen, the carburetor of the present invention includes carburetor body 10, oil feeder 20 and check valve 30.Oil feeder 20 is connected on carburetor body 10, and check valve 30 is connected on oil feeder 20.
Oil feeder 20 includes oil feeder mounting seat 21, pump oil part 22, pump oil part ring for fixing 23 and oil feeder spring 24.
Oil feeder mounting seat 21 is connected on carburetor body 10.Carburetor body 10 includes intake channel 11 and lower cover 12, and lower cover 12 has district in oil, and intake channel 11 is connected with district in oil.
Oil feeder mounting seat 21 includes inlet channel 211, and intake channel 11 is connected with inlet channel 211.
Pump oil part 22 has air inlet 221, and wherein, air inlet 221 is preferably provided in the bottom of pump oil part 22.Pump oil part 22 is compressible, and the pump oil part 22 of the present invention is for pump outermost layer of skin bowl, but is not limited.Pump oil part 22 is connected in oil feeder mounting seat 21 by pump oil part ring for fixing 23, thus forming an appearance gas chamber 25 between pump oil part 22 and oil feeder mounting seat 21, holding gas chamber 25 and being connected with inlet channel 211.
Oil feeder mounting seat 21 also includes spring butting section 212, and oil feeder spring 24 is arranged in appearance gas chamber 25, and oil feeder spring 24 one end compresses the bottom of pump oil part 22, and the other end compresses the spring butting section 212 of oil feeder mounting seat 21.
Gas enters from the air inlet 221 of pump oil part 22 and holds gas chamber 25, and is entered the intake channel 11 of carburetor body 10 by inlet channel 211, and then enters the district in oil of lower cover 12.
Check valve 30 includes one-way valve seat 31, spheroid 32 and one-way valve spring 33.Wherein, one-way valve seat 31, spheroid 32 and one-way valve spring 33 are set in turn in the inlet channel 211 of carburetor mounting seat 21 according to airintake direction.Wherein, airintake direction specifically refers to the direction in district in oil that the air inlet 221 of air from pump oil part 22 enters the lower cover 12 of carburetor body 10.So, the inlet channel 211 of oil feeder 20 and the intake channel 11 of carburetor body 10 are controlled by check valve 30, unilaterally connected between the district in oil of the lower cover 12 of oil feeder 20 to carburetor body 10.
Wherein, inlet channel 211 has stage portion 213, and one-way valve spring 33 one end compresses spheroid 32, and the other end compresses stage portion 213.
Consulting the partial sectional view of the second embodiment of the carburetor that Fig. 4 and Fig. 5, Fig. 4 are the present invention, Fig. 5 is the F place enlarged drawing of Fig. 4.Intake channel 11 is divided into the first intake channel 111 and the second intake channel 112.Wherein, the first intake channel 111 is connected with inlet channel 211, and the second intake channel 112 is connected with the district in oil of lower cover 12.In the present embodiment, the one-way valve seat 31 of check valve 30, spheroid 32 and one-way valve spring 33 are set in turn in the first intake channel 111 according to airintake direction.Wherein, the first intake channel 111 has support portion 113, and one-way valve spring 33 one end compresses spheroid 32, and the other end compresses support portion 113.
Consulting the partial sectional view of the 3rd embodiment of the carburetor that Fig. 6 and Fig. 7, Fig. 6 are the present invention, Fig. 7 is the G place enlarged drawing of Fig. 6.In the present embodiment, the one-way valve seat 31 of check valve 30, spheroid 32 and one-way valve spring 33 are set in turn in the second intake channel 112 according to airintake direction.Wherein, the second intake channel 112 has stage portion 114, and one-way valve spring 33 one end compresses spheroid 32, and the other end compresses stage portion 114.
Hereinafter the work process of carburetor and oil feeder thereof is introduced.When oil feeder 20 does not work, check valve 30 is in closed mode, and namely one-way valve spring 33 compresses spheroid 32, by spheroid 32 tight abutment on the blow vent of one-way valve seat 31.During oil feeder work, extrusion pump oil part 22, oil feeder spring 24 shrinks, and the air inlet 221 of air from pump oil part 22 enters to appearance gas chamber 25 and then the spheroid 32 of promotion check valve 30, and air enters carburetor body 10 from the blow vent of one-way valve seat 31.When oil feeder 20 does not work, stop extrusion pump oil part 22, one-way valve spring 33 return makes spheroid 32 and one-way valve seat 31 closely cooperate, the district in oil of the lower cover 12 of carburetor body 10 does not connect because check valve 30 is closed with the appearance gas chamber 25 of oil feeder 20, thus stoping the gasoline in district in oil to enter from carburetor body 10 the pump oil part 22 of oil feeder 20.
Additionally, the material of the spheroid 32 of check valve 30 can be steel ball or the copper ball of metal class, it is also possible to be the baton round of non-metal kind, as long as intensity and hardness reach the requirement of the present invention.
Certainly; the present invention also can have other various embodiments; when without departing substantially from present invention spirit and essence thereof; those of ordinary skill in the art are when can make various corresponding change and deformation according to the present invention, but these change accordingly and deformation all should belong to the scope of the claims appended by the present invention.
