Description
The utility model relates to a kind of gasoline engine mixed air heater.
At present automobile engine heater kind is a lot, publication number CN20589351 and two patent disclosures of CN92243915 two kinds of air inlet pipe heaters, relatively simple for structure, compact; But because the PTC potsherd is to be bonded on the radiator by conducting resinl, make the resistance and the heating properties of heater all can not get guaranteeing like this, simultaneously influenced by ambient temperature very big, easily aging, life-span is short, and complicated operation, is not easy to produce in batches, because of being provided with, its assembling face realizes sealing again, heater internal components vulnerable to pollution, corrosion under the inner adverse circumstances of air inlet pipe and influence its performance and life-span.
The purpose of this utility model be to provide a kind of gasoline engine with the mixed air heater to overcome the deficiency that prior art exists.
Overall structure of the present utility model is:
Gasoline engine mixed air heater comprises housing (8), conductivity ceramics sheet (6); Rear pressing cover (5) is connected with housing (8) rear portion tight fit, rear pressing cover (5) inboard is provided with location-plate (4), location-plate (4) inboard is provided with wire column (1) and lead (3), conductivity ceramics sheet (6) and anterior inboard concavo-convex cooperation of housing (8), connected spring (2) between lead (3) and the conductivity ceramics sheet (6), wire column (1) front end connects conduction plug connector (12), and housing (8) one side external surfaces are provided with thermal column (7).
Concrete structure of the present utility model also has:
Be provided with sealing column (11) between housing (8) front end and the wire column (1).
The anterior arranged outside of housing (8) has packing ring (9) and retaining member (10).
Be provided with fluid sealant between rear pressing cover (5) and the housing (8).
Accompanying drawing of the present utility model has:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the right view of Fig. 1.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
The overall structure of present embodiment as shown in Figure 1, 2, 3, wherein adopt between rear pressing cover (5) and the housing (8) after screw (13) immovable fitting again with refractory seals glue and realize sealing between the two, PTC conductivity ceramics sheet (6) and housing (8) are inboard concavo-convexly to be cooperated and compresses by spring (2), the retaining member (10) that is arranged at behind the packing ring (9) is elastic washer and nut, thermal column (7) and housing (8) integrated molding, thermal column (7) is the circular platform type thermal column, be distributed in housing (8) surface, all the other structures as described above.
The utility model is work like this:
This heater is inserted in the engine charge tube cavity of automobile carburetor bottom, the conduction plug connector of heater is connected to power supply in the car, PTC conductivity ceramics sheet is heatable and distributes by housing and thermal column.
The obtained technological progress of the utility model is:
This heater has structurally been exempted the conducting element premature oxidation, and conducting resinl quality and bonding quality The bad impact that causes, and convenient operation easily realize batch production, saves energy and production cycle, heating The life-span of device can be enhanced about more than once than like product.
