Description

Grass-mowing machine carburetor pump cover
Technical field
The present invention relates to carburetor pump cover technical field, especially a kind of pump cover structure of grass-mowing machine carburetor.
Background technique
Currently, diaphragm flat-absorpting type band oil vacuole grass-mowing machine carburetor generallys use ZAMA money structure type, and diaphragm flat-absorpting type Chain saw carburetor is that magnificent Boluo carburetor is in the majority again, poor in the main structure of two carburetor for carburetor manufacturer Different very big, special machine tool cannot be general, and process equipment is caused to increase, and it is inconvenient to cause much to produce.Diaphragm flat-absorpting type band oil vacuole is beaten Careless machine carburetor body cannot be general with diaphragm flat-absorpting type chain saw carburetor ontology, produces two kinds of carburetors and respective ontology is needed to open Mould processing, the tooling for needing to process and assemble is many kinds of, and the pattern of accessory is also very more, so that production cost increases.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of grass-mowing machine carburetor pump cover, structurally reasonable, does not need another ZAMA ontology is done in outer die sinking, saves great amount of cost.
The present invention provides a kind of grass-mowing machine carburetor pump cover, including lid, and oil vacuole, the oil vacuole are provided on the lid It combining to form pressing chamber with lid end face, the covered body wall is provided with oil-recovery tank, it is formed with the first guide groove in the pressing chamber, First guide groove is connected with oil-recovery tank, and unidirectional valve component is provided in first guide groove and forms closing to the first guide groove, The second guide groove for being connected with carburetor oil pocket is additionally provided on the lid, second guide groove one end and pressing chamber connect Logical, the other end extends to outside lid and is formed on lid the connector be connected with carburetor oil pocket, is arranged at the connector There is the check valve assembly for preventing reflux.
The beneficial effect being arranged in this way is: being arranged to this form, when pressing oil vacuole, pressing chamber becomes smaller and pressure increases Greatly, so that the pressure of pressing chamber is greater than beat the grass sump and carburetor oil pocket pressure, so that unidirectional valve component is opened, and non-return Valve module encloses the second guide groove, so that gas enters sump of beating the grass in pressing chamber, when unclamping oil vacuole, oil vacuole is being agitated During reset, presses pressure in chamber and be less than carburetor oil pocket and sump pressure of beating the grass, but have unidirectional valve component Effect, the first guide groove be in closed state, and check valve assembly is opened so that carburetor oil pocket with press chamber and be connected so that Gas in carburetor oil pocket enters pressing chamber, so that pressure is strong less than oil pressure of beating the grass in carburetor oil pocket, to realize vapour Oil sucks carburetor oil pocket from fuel tank, and oil, making is sucked out from sump of beating the grass by pressing and unclamping oil vacuole energy auxiliary carburetor Full of oil in oily device oil pocket, oil vacuole pump oil function is realized, meets the demand of grass-mowing machine, while overall structure processing, assembly Simply, cost is saved.It can allow China's Boluo money ontology and produce diaphragm flat-absorpting type band oil vacuole carburetor;It only need to the ontology of Boluo magnificent A small amount of modification is made in processing, is not needed in addition to be opened and is done ZAMA ontology, eliminates the matched accessory of ZAMA ontology, this chaeta Mold tool, ontology processing special plane and frock clamp etc. used, largely save cost.
It includes several leaflets that the present invention, which is further arranged to the unidirectional valve component, in described leaflet one end and the first guide groove Wall connection, the other end are free end and separate pressing chamber setting, and adjacent leaflet free end is bonded to each other to be formed to the first guide groove Closing.
The beneficial effect being arranged in this way is: using the above scheme, the unidirectional valve component being arranged in this way is pressed in oil vacuole When pressure, pressing chamber becomes smaller and pressure increases, so that the pressure of pressing chamber is greater than sump pressure of beating the grass, so that leaflet is washed open, Realize with the conducting of oil-recovery tank, when unclamping oil vacuole, since leaflet free end is arranged far from pressing chamber, will not because of pressure difference and It opens, to realize unidirectional blocking, this structure is simple, is conducive to realize, effectively realizes the effect of unidirectional blocking.
It includes valve block and valve seat that the present invention, which is further arranged to the check valve assembly, and the valve seat is arranged in connector In, the conducting that link slot is formed outside the second guide groove and lid is provided on the valve seat, the valve block is slidably arranged in link slot Closing or unlatching of the middle formation to connector, the link slot are provided with positioning ring, the positioning ring far from one end of connector Several collision arm, which are extended with, to valve block forms the limit slid to valve block.
The beneficial effect being arranged in this way is using the above scheme, check valve assembly to be arranged to this form, oil vacuole by To when pressing, pressing chamber becomes smaller and pressure increases, so that pressure is greater than carburetor oil pocket pressure, so that valve block is under pressure It is fixed contradict at connector, form the closing to connector, when unclamping oil vacuole, oil vacuole during agitating reset, Press chamber in pressure be less than carburetor oil pocket pressure, thus diaphragm by another lateral pressure effect and float so that change Gas in oily device oil pocket enters pressing chamber, so that pressure is strong less than oil pressure of beating the grass in carburetor oil pocket, to realize gasoline From the sucking of fuel tank.Positioning ring is set simultaneously, and collision arm is set, avoid when valve block is by carburetor oil pocket pressure action and Link slot is closed, guarantees that there are the gaps that gas flows, this structure is simple, is conducive to realize, has effectively played the work of check-valves With.
The present invention is further arranged to circumferentially arranged defining flange in the link slot and is formed to valve block abjection valve seat Limit.
The beneficial effect being arranged in this way is: using the above scheme, effectively limiting to valve block, valve block is avoided to deviate from, protect Demonstrate,prove integrally-built using effect.
The present invention is further arranged to be provided with locating slot on the lid end face, and the oil vacuole extends simultaneously into locating slot Cooperate with locating slot swelling, is circumferentially additionally provided with door along locating slot on the lid, the door lid is located at shape on locating slot The fixation of pairs of oil vacuole.
The beneficial effect being arranged in this way is: using the above scheme, can effectively be fixed to oil vacuole, while seal effect Fruit is good, guarantees integrally-built using effect, while structure is simple, is conducive to realize.
