Specific implementation mode
The illustrative embodiments of the disclosure are more fully described below with reference to accompanying drawings.Although showing this public affairs in attached drawing
The illustrative embodiments opened, it being understood, however, that may be realized in various forms the disclosure without the reality that should be illustrated here
The mode of applying is limited.It is to be able to be best understood from the disclosure on the contrary, providing these embodiments, and can be by this public affairs
The range opened completely is communicated to those skilled in the art.
Embodiment according to the present utility model proposes a kind of integrated fuel filter device.As shown in Figure 1, this reality
Include fuel preliminary filter 1, secondary fuel oil filter 2, fuel filter filter block 3 and hand pressure with novel integrated fuel filter device
Pump 4.Wherein, fuel preliminary filter 1, secondary fuel oil filter 2 and handlance 4 are arranged on fuel filter filter block 3, and handlance 4 is set
The downstream of secondary fuel oil filter 2 is set in the downstream of fuel preliminary filter 1 and be located at, handlance oil is provided in fuel filter filter block 3
Road so that fuel oil enters handlance oil duct after capable of being filtered via fuel preliminary filter 1 when opening handlance 4, and passes through hand pressure
Pump oil road is by the fuel pumping after coarse filtration to secondary fuel oil filter 2.Preferred embodiment according to the present utility model, handlance 4
It is plunger pump.
Preferred embodiment according to the present utility model, as shown in Figures 2 to 4, handlance 4 include pump cover 5 and pump seat
6, return spring 7 is provided between pump cover 5 and pump seat 6, pump cover 5 is provided with the first self-locking structure, and pump seat 6 is provided with can be with
