Detailed description of the invention
Fig. 1 is the structural schematic diagram of the embodiments of the present invention one；
Fig. 2 is the circuit diagram of the embodiments of the present invention one；
Fig. 3 is the circuit diagram of the embodiments of the present invention two.
Specific embodiment
Below with reference to embodiment and attached drawing, the utility model is described in further detail.
Embodiment one is arranged at the headstock of car body as shown in Figure 1, a kind of Pcv system antifreeze vehicle, is provided with car body
There are engine and vehicle power supply, which is provided with Pcv system, which is provided with full load respiratory siphon 1 and snorkel
2, the snorkel 2 and full load respiratory siphon 1 are successively connected to air induction hose 3 along the airintake direction of the air induction hose 3 of engine.For
The air mass flow of control air induction hose 3 is provided with air throttle in air induction hose 3 between snorkel 2 and full load respiratory siphon 1
4。
One end of the snorkel 2 is connected to air induction hose 3, and the other end is connected to the crankcase 5 of engine, and the full load is exhaled
One end of suction pipe 1 is connected to air induction hose 3, and the other end is connected to crankcase 5, the full load respiratory siphon 1 and oil through gs-oil separator 6
The connectivity part of gas separating device 6 is provided with Pcv valve 7, being turned on and off for full load respiratory siphon 1 is controlled by Pcv valve 7, to control
The breathing of engine processed.
After the separation of gs-oil separator 6, the machine oil in oil gas is separated for oil gas in crankcase 5, again into
Enter in oil sump.And the gasoline and steam in oil gas then pass through Pcv valve 7 and enter in full load respiratory siphon 1, and exhale along full load
Suction pipe 1 enters in air induction hose 3.
Since the cold air in air induction hose 3 can make steam congeal into ice in full load respiratory siphon 1, blocking full load is exhaled
Suction pipe 1 interrupts the ventilation of crankcase 5.In order to avoid steam condenses in full load respiratory siphon 1, in full load respiratory siphon 1
It is coated with electric heating sheets 8 on inner wall, full load respiratory siphon 1 is heated by electric heating sheets 8, steam is avoided to exhale in full load
Condensation in suction pipe 1.
In order to improve heat conduction efficiency, the full load respiratory siphon 1 is made of metal material, such as aluminium.It is described complete negative
Lotus respiratory siphon 1 is connected to through adapter 9 with air induction hose 3, which is made of heat-barrier material, such as glass fibre, such energy
Completely cut off the heat transfer on full load respiratory siphon 1 to air induction hose 3.
The electric heating sheets 8 connect vehicle power supply through temperature detect switch (TDS), and in the present embodiment, temperature detect switch (TDS) is that KSD301 is normally closed
Type temperature detect switch (TDS), one of contact of the temperature detect switch (TDS) connect the anode of vehicle power supply through resistance R1, and another contact connects through conducting wire
The anode of electric heating sheets 8, the cathode ground connection of electric heating sheets 8.
Upon a drop in temperature, two contact conductings, are connected between electric heating sheets 8 and vehicle power supply, and electric heating sheets 8 obtain electric hair
Heat heats full load respiratory siphon 1, and when temperature increases, contact is disconnected.
Embodiment two, embodiment two is roughly the same with embodiment one, and the main distinction is: the electric heating sheets 8 are through switching
Control circuit connects vehicle power supply, since Pcv system is more easily impacted under extreme environment temperature, and in extreme environment
At a temperature of, conventional switch controller cannot work well, and therefore, the ON-OFF control circuit of the present embodiment is provided with luminous two

Other end ground connection, the normal open switch of the relay are serially connected between electric heating sheets 8 and vehicle power supply.
The vehicle-mounted ECU is connected with the temperature sensor for detecting environment temperature, and vehicle-mounted ECU is examined by temperature sensor
Ambient temperature is surveyed, when ambient temperature drops to the temperature threshold of setting, vehicle-mounted ECU control I/O interface persistently exports electricity
Ordinary mail number, light emitting diode obtain electroluminescence.Phototriode sense light emitting diode issue light after be connected, thus make after
Electric apparatus coil is powered, and the normal open switch closure of relay is connected, electric heating sheets 8 obtain electric hair between electric heating sheets 8 and vehicle power supply
Heat heats full load respiratory siphon 1.
Due to phototriode at low temperatures photoelectric current be affected by temperature it is smaller than the influence that dark current is subject to,
So at low temperatures, phototriode can more accurately detect the light of light emitting diode sending, to more accurately control
Electric heating sheets 8 processed are heated.
It is obtained by actual tests:
Under subzero 20 degrees Celsius of environment temperature, the test vehicle for not installing heating device travels 2h in continuous high speed
Afterwards, check that ice cube just occur in respiratory siphon and inlet manifold river conjunction.And this by cold wind to blow swiped through ice cube very hard, will exhale
Suction pipe neck blocks 85%, and dramatically increases with crankcase pressure, and abnormal jump out also occurs in dipstick.
Under subzero 20 degrees Celsius of environment temperature, the test vehicle of heating device is installed after continuous high speed travels 5h,
Without ice cube in crankcase bleed pipe, and crankcase pressure is without dramatically increasing.
Finally, it should be noted that foregoing description is only the preferred embodiment of the utility model, the common skill of this field
Art personnel are under the enlightenment of the utility model, under the premise of without prejudice to the utility model aims and claim, can make
