Description
Technical field
The utility model relates to sensor field, especially a kind of liquid level sensor with heating function.
Background technology
Now for the liquid level sensor of vehicle many be all do not possess heating function, when vehicle in the winter time or the work of some cold districts time, often cause liquid level sensor normally not use because of freezing.
Summary of the invention
The technical matters that the utility model mainly solves is to provide a kind of efficient, practical liquid level sensor being applicable to cold environment
The utility model is the technical scheme solving the problems of the technologies described above employing:
A kind of liquid level sensor with heating function, include and be arranged at the holder on top, the base of bottom and the pipe structure between holder and base, described pipe structure comprises electron tube, pipette and liquid back pipe, be provided with between described pipette and liquid back pipe and independently heat pipette, PTC calandria is placed in heating pipette, and described PTC calandria is clamped and fastened in heating pipette;
Filter was established in described base lower end, filter was provided with some filter bores;
Described pipe structure outside covers screen pack, and described screen pack bottom of crossing is connected with base.
Further, described liquid level sensor is provided with NTC temperature sensor.
Further, described screen pack is arranged around pipette, heating pipette and liquid back pipe.
Further, the bottom of described pipette, heating pipette and recirculatory pipe is provided with the concave surface for assembling screen pack.
Further, described screen pack is fixed by intermediate plate and pipe structure.
Further, described filter and base are connected together.
Further, described filter is provided with the hole supporting with liquid back pipe.
Further, the duroplasts material that is formed in one of described filter.
The beneficial effects of the utility model are:
1. the utility model by arranging PTC calandria on liquid level sensor, can ensure the normal use at cold conditions lower sensor.
The mounting means of 2.PTC calandria is fast very convenient, does not need extra setting tool, only needs the relevant position at the two ends of PTC calandria in heating pipette to offer shrinkage pool, namely can realize the fixing of PTC calandria, the very cost-saving and set-up time.
3. PTC calandria is arranged on pipette interior, effectively can ensures the bulk temperature of liquid in carrier fluid case, not only ensure the normal use of liquid level sensor, ensure work efficiency and the accuracy of the utility model liquid level sensor simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Fig. 2 is the structural representation of a kind of embodiment filter plate of the utility model.
Fig. 3 is a kind of embodiment concave surface of the utility model partial schematic diagram.
In figure: 1 is holder, 2 is liquid back pipe, and 3 is filter, and 4 is screen pack, and 5 is pipette, and 6 is heating pipette, and 7 is geometrical clamp, and 8 is liquid outlet, and 9 is electron tube, and 10 is filter bores, and 11 is hole, and 12 is intermediate plate, and 13 is concave surface, and 14 is base.
Embodiment
Refer to Fig. 1, be a kind of embodiment of the utility model, comprise: holder 1, liquid back pipe 2, filter 3, screen pack 4, pipette 5, heating pipette 6, geometrical clamp 7, liquid outlet 8.
Liquid level sensor of the present utility model in use, switch on power, when environment temperature is too low, start PTC calandria, at this moment PTC calandria can heat the liquid in carrier fluid case, ensure the normal work of pipette and liquid back pipe, also ensure that the normal work of the floating drum on electron tube simultaneously, ensure that high efficiency and the stability of working sensor.
As shown in the figure, it is inner that PTC calandria is arranged on heating pipette 6, by carrying out clipping operation to PTC calandria in heating pipette 6, can be very easy fix PTC calandria, PTC calandria is made to be difficult to come off, be arranged between pipette and liquid back pipe 2 by heating pipette 6 simultaneously, heating pipette 6 is provided with the geometrical clamp 7 in order to fixing heating pipette, geometrical clamp 7 is by firmly firm to pipette 5, liquid back pipe 2 and heating pipette 6.
By screen pack 4 part being covered pipette 5, liquid back pipe 2 and heating pipette 6, not comprising electron tube 9, both effectively can ensure the filter effect to liquid, effectively reducing again the impact of filtration unit on electron tube 9 simultaneously.
The bottom of pipette 5, heating pipette 6 and liquid back pipe 2 is provided with the concave surface for assembling screen pack.
NTC calandria is installed on holder or on pipe structure or on filtration unit.
Refer to Fig. 2, comprising: filter bores 10, hole 11.
The size of hole 11 by matching with pipette 6, the absorption efficiency reduction that because of the obstruction of filter 3 cause of pipette when imbitition can be prevented, simultaneously by arranging filter bores 10 on filter 3, namely filter effect can be ensured, dismounting is simultaneously very convenient, greatly reduces assembly difficulty.
Filter 3 surrounding is provided with some projections, and the base 14 of liquid level sensor is provided with the shrinkage pool matched with the projection of filter 3, when assembling filter, directly projection and shrinkage pool one_to_one corresponding can be realized being connected together.
Refer to Fig. 3, be the partial schematic diagram of the utility model screen pack, comprise: intermediate plate 12, concave surface 13.
Screen pack fixed by intermediate plate 12, and screen pack is placed in concave surface 13, can realize highly stable placement
The utility model, by arranging PTC calandria on liquid level sensor, can ensure the normal use at cold conditions lower sensor.The mounting means of PTC calandria is fast very convenient, does not need extra setting tool, only needs the relevant position at the two ends of PTC calandria in heating pipette 6 to offer shrinkage pool, namely can realize the fixing of PTC calandria, the very cost-saving and set-up time.PTC calandria is arranged on heating pipette in 6, effectively can ensure the bulk temperature of liquid in carrier fluid case, not only ensure the normal use of liquid level sensor, ensure work efficiency and the accuracy of the utility model liquid level sensor simultaneously.
