Embodiment

Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail, and object is to help those skilled in the art to have more complete, accurate and deep understanding to design of the present utility model, technological scheme, and contributes to its enforcement.

As shown in Figure 1, a kind of gasoline filter of the utility model, comprises shell 1 and is located at the element kit in the cavity volume of shell 1.Shell 1 is the cylindrical housings member of lower ending opening, inner hollow, and inner hollow part is the cavity volume that holds element kit and gasoline.Element kit comprises upper end cap 4, lower end cap 5 and refill sub-assembly 6, and the upper end of refill sub-assembly 6 and upper end cap 4 glueds joint and be connected, and lower end is connected with lower end cap 5 splicing, and the center of refill sub-assembly 6 is to allow gasoline after filtration flow to the center hole of oil outlet.For this gasoline filter, as shown in Figure 1, be provided with the oil inlet pipe 2 being communicated with the cavity volume of shell 1 in the upper end of shell 1, this oil inlet pipe 2 is the filler opening places at the vertical center, upper-end surface that is fixed on shell 1, oil inlet pipe 2 is connected with external oil pipe, makes gasoline enter shell 1 inside by oil inlet pipe 2.The lower end cap 5 of element kit is fixedly connected with shell 1 at the lower ending opening of shell 1, on lower end cap 5, be also provided with the oil outlet tube 3 being communicated with the center hole of refill sub-assembly 6, this oil outlet tube 3 is to stretch out towards shell 1 outside downwards, for being connected with external oil pipe, gasoline after refill sub-assembly 6 filters enters in oil outlet tube 3 through center hole, finally flows in the external oil pipe being connected with oil outlet tube 3.In addition, the refill sub-assembly 6 of element kit is made up of smart filter core 61 and coarse filter element 62, and coarse filter element 62 is the outsides that are enclosed within smart filter core 61, and links into an integrated entity with smart filter core 61.Essence filter core 61 is coaxial with coarse filter element 62, and both are equal in length, and the top and bottom of smart filter core 61 and coarse filter element 62 are connected with upper end cap 4 and lower end cap 5 respectively.Coarse filter element 62 and smart filter core 61 are set, and the gasoline entering in shell 1 first filters through coarse filter element 62, is then filtered by smart filter core 61, is finally flowed out by oil outlet tube 3.Coarse filter element 62 and smart filter core 61 are set, can improve the filtering effect to gasoline.

Specifically, oil inlet pipe 2 and oil outlet tube 3 are all coaxial with shell 1 and element kit, oil inlet pipe 2 and being formed in one with shell 1, and oil outlet tube 3 and being formed in one with lower end cap 5, convenient processing and manufacture, filter cleaner overall structure is simple.

As shown in Figure 1, because lower end cap 5 is fixedly connected with urceolus, the external diameter of lower end cap 5 is larger than the external diameter of shell 1, and lower end cap 5 is lower ends that the flange that arranges by its outward edge is enclosed within shell 1, and be welded to connect at flange place and shell 1, guarantee to be connected reliably with shell 1.The external diameter of the upper end cap 4 of element kit is less than the internal diameter of shell 1, leaves gap between the two, guarantees that entering gasoline shell 1 from oil inlet pipe 2 can flow downward and enter refill sub-assembly 6.

As depicted in figs. 1 and 2, on oil inlet pipe 2, be provided with a pipe clamp 7 for fixing external oil pipe, this pipe clamp 7 is to be sleeved on oil inlet pipe 2, pipe clamp 7 centers are provided with the center hole that allows oil inlet pipe 2 pass, on the sidewall of pipe clamp 7, be also provided with annular restraining groove 71, correspondingly on oil inlet pipe 2, be provided with radially outwardly ringwise protrudingly 9, projection 9 can embed in the restraining groove 71 of pipe clamp 7, thereby pipe clamp 7 can be fixed on oil inlet pipe 2.Also be provided with a guiding conical surface 72 at the outer surface of pipe clamp 7, this guiding conical surface 72 is the belows that are positioned at restraining groove 71, and the miner diameter end of the guiding conical surface 72 upper, bigger diameter end under, the external diameter of the bigger diameter end of the guiding conical surface 72 is larger than the external diameter of projection 9.The effect of the guiding conical surface 72 is: in oil inlet pipe 2 inserts external oil pipe time, after external oil pipe contacts with the guiding conical surface 72 of pipe clamp 7, the conical surface 72 that leads on the one hand has guide effect, can guarantee that oil inlet pipe 2 can continue to insert in external oil pipe, the conical surface 72 that leads on the other hand can make external oil pipe distending, can make external oil pipe tightly envelope pipe clamp 7, thereby realize and being fixedly connected with of external oil pipe.Therefore, the pipe clamp 7 of said structure is set on oil inlet pipe 2, can makes oil inlet pipe 2 reliable with the installation of external oil pipe, be difficult for getting loose.

As shown in figures 1 and 3, same, on oil outlet tube 3, be also provided with a pipe clamp 7 for fixing external oil pipe, the structure of the pipe clamp 7 on oil outlet tube 3 is identical with the structure of the pipe clamp 7 on oil inlet pipe 2, difference is that pipe clamp 7 on oil inlet pipe 2 and oil outlet tube 3 is for being oppositely arranged, the guiding conical surface 72 that is the pipe clamp 7 on oil outlet tube 3 is the tops that are positioned at restraining groove 71, and the miner diameter end of the guiding conical surface 72 under, bigger diameter end is upper, accordingly, on oil outlet tube 3, be also provided with one radially outwardly ringwise protruding 9, projection 9 can embed in the restraining groove 71 of pipe clamp 7.

Pipe clamp 7 on oil inlet pipe 2 and oil outlet tube 3 all adopts nylon material to make, and has certain distortion function, can coincide preferably with external oil pipe, guarantees to connect reliably, and can not damage oil inlet pipe 2, oil outlet tube 3 and external oil pipe.

Projection 9 on oil inlet pipe 2 and oil outlet tube 3, be by the sidewall of oil inlet pipe 2 and oil outlet tube 3 radially toward the outer side distending form.

As shown in Figure 1, be set with a gum cover 8 in the port, upper end of oil inlet pipe 2, this gum cover 8 be enclosed within on oil inlet pipe 2 and with oil inlet pipe 2 be drive fit, this gum cover 8 is for by the upper end port closed of oil inlet pipe 2, prevents that the impurity such as dust from entering in shell 1 from oil inlet pipe 2.Also be set with a gum cover 8 in the port, lower end of oil outlet tube 3, this gum cover 8 be enclosed within on oil outlet tube 3 and with oil outlet tube 3 be drive fit, this gum cover 8 is for by the lower end port closed of oil outlet tube 3, prevents that the impurity such as dust from entering in shell 1 from oil outlet tube 3.

Below by reference to the accompanying drawings the utility model is exemplarily described.Obviously, the utility model specific implementation is not subject to the restrictions described above.As long as having adopted the improvement of the various unsubstantialities that method of the present utility model design and technological scheme carry out; Or without improvement, above-mentioned design of the present utility model and technological scheme are directly applied to other occasion, all within protection domain of the present utility model.
