Abstract
The utility model relates to a waterproof ventilative structure of controller for electric fuel pump, including insulating support, insulating support one end connect the upper cover and with the upper cover between form the controller installation cavity, install controller, its characterized in that in the controller installation cavity: the one end that insulating support was kept away from to the upper cover is equipped with the exhaust branch who is linked together with the controller installation cavity, the one end that the controller installation cavity was kept away from to the exhaust branch is provided with waterproof ventilative structure, the beneficial effects of the utility model are that: be provided with waterproof ventilative structure, solved the harm that the breathing phenomenon caused between to controller and upper cover, insulation, and the ventilated membrane protection tube that sets up has promoted the life of waterproof ventilated membrane, can use widely.
Description
Technical Field
The utility model relates to an electronic fuel pump field, concretely relates to a waterproof ventilative structure of controller for electronic fuel pump.
Background
Generally can be sealed with whole controller casing for preventing that water from getting into in the controller cavity among the electronic fuel pump, because the controller generates heat at the in-process of operation, lead to inside the heating expansion of whole controller, long-term opening stops work and can make the controller cavity have one kind and breathe the same expansion and contraction like, all has certain harm to controller, controller casing, and this will lead to the controller casing to leak in the past.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to solve the above-mentioned deficiencies of the prior art,
a waterproof ventilative structure of controller for electric fuel pump is provided.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a waterproof ventilative structure of controller for electric fuel pump, including insulating support, insulating support one end is connected the upper cover and is formed the controller installation cavity between the upper cover, install the controller in the controller installation cavity, its characterized in that: the one end that the insulating support was kept away from to the upper cover is equipped with the exhaust branch who is linked together with the controller installation cavity, the one end that the controller installation cavity was kept away from to the exhaust branch is provided with waterproof ventilative structure.
Adopt above-mentioned technical scheme, the exhaust branch who is linked together with the controller installation cavity is set up through the one end of keeping away from insulating support at the upper cover, the one end of keeping away from the controller installation cavity at exhaust branch sets up waterproof ventilative structure, make the gas that the respiratory effect produced pass through waterproof ventilative structure discharge controller installation cavity, and waterproof ventilative structure makes outside moisture can't get into the controller installation cavity again, guarantee that the waterproof performance of controller installation cavity has solved respiratory effect again, the life of controller has been promoted greatly.
The waterproof and breathable structure for the controller of the electric fuel pump can be further configured as follows: the waterproof breathable structure comprises a waterproof breathable film arranged at one end of the exhaust branch pipe, a breathable film protection pipe is sleeved on the outer end face of the exhaust branch pipe, and a drainage structure is arranged on the breathable film protection pipe.
Adopt above-mentioned technical scheme, because the ventilated membrane is extremely thin and the touching is breakable, and is impaired easily, consequently establish the ventilated membrane protection tube at the outer terminal surface cover of exhaust branch, protect waterproof ventilated membrane through the ventilated membrane protection tube, nevertheless have the intraductal ponding problem of ventilated membrane protection after increasing the ventilated membrane protection tube, consequently set up drainage structure on the ventilated membrane protection tube, even guarantee that the intraductal ponding of ventilated membrane protection, the surface of water also can not contact with waterproof ventilated membrane.
The waterproof and breathable structure for the controller of the electric fuel pump can be further configured as follows: the drainage structure is at least two drain holes which are arranged on the outer wall of the breathable film protection pipe at intervals on the same plane.
Adopt above-mentioned technical scheme, even two at least wash ports that ventilated membrane protection tube outer wall set up in the coplanar guarantee that even also can restrict the water level below the wash port through the wash port with the intraductal ponding of ventilated membrane protection, wash port to the straight-line distance between the waterproof ventilated membrane be greater than 0 all the time, guarantee that the water of going out in the wash port can not contact with waterproof ventilated membrane.
The utility model has the advantages that: be provided with waterproof ventilative structure, solved the harm that the breathing phenomenon caused between to controller and upper cover, insulation, and the ventilated membrane protection tube that sets up has promoted the life of waterproof ventilated membrane, can use widely.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
Referring to FIG. 1: the utility model provides a waterproof ventilative structure of controller for electric fuel pump, including insulating support 1, 1 one end of insulating support is connected upper cover 2 and is formed controller installation cavity 3 between the upper cover 2, install controller 4 in the controller installation cavity 3, the one end that insulating support 1 was kept away from to upper cover 2 is equipped with the exhaust branch 21 that is linked together with controller installation cavity 3, the one end that controller installation cavity 3 was kept away from to exhaust branch 21 is provided with waterproof ventilative structure, waterproof ventilative structure is including setting up in the waterproof ventilated membrane 22 of exhaust branch 21 one end, the outer terminal surface cover of exhaust branch 21 is equipped with ventilated membrane protection tube 23, be provided with drainage structures on ventilated membrane protection tube 23, drainage structures is two at least wash ports 24 that ventilated membrane protection tube 23 outer wall set up the interval on the coplanar.
